Core Values Essay Example for Free
Core Values Essay Inspired by the charism of Saint Marcellin Champagnat, Notre Dame of Marbel University anchors its faith and life on the following core values as foundational qualities with which the Marist Brothers, Mission Partners, and students approach the entire educational process and academic atmosphere of the University: Family Spirit, Marian, Love of Work, Preference for the Least Favored, Quality Education, Integrity of Creation, and Culture-sensitivity. Family Spirit St. Marcellin Champagnatââ¬â¢s great desire and legacy was in the style of relationship he encouraged between teachers and students- a relationship premised on love and expressed in a style which Marcellin called ââ¬Å"family spirit. â⬠Akin to the characteristic of a good family are: a warmth of welcome, acceptance, belongingness and authentic concern which should prevail where everyone has a sense of being valued and believed in, regardless of their role or their social standing. Marian Mary is for us the perfect model of the Marist Educator, as she was for Marcellin. As a woman, a layperson and Jesusââ¬â¢ first follower, she is our inspiration in living out personal faith and virtue of simplicity. As an educator of Jesus at Nazareth, she inspires our pedagogical approach. The Marian aspect of our spirituality is expressed above all, in our identifying with her attitudes towards others and to God. She is in our midst, a symbol of unity and mission, a witness to Godââ¬â¢s solidarity with people in their needs and sufferings. Love of Work Love of work implies a cheerful and careful preparation of all the things one does. It values the dignity of work as a powerful means of self-fulfillment, of giving purpose and meaning to life, and of contributing to the general economics, social and cultural well-being. It is manifested through a deep sense of personal planning and motivation that shows itself in the good use of time, talent and initiative. Preference for the Least Favored Preference for the least favored is to be with those who are excluded from the mainstream of society, and those whose material poverty leads to deprivation in relation to health, family life, schooling, and educational values. With the emergence of social and cultural challenges confronting the world, preference to the least favored means being concerned toward the youth who are affected by the social, political, and cultural problems of the society. Quality Education A Marist school is a center of learning, of life and of evangelizing. It leads students ââ¬Å"to learn, to know, to be competent, to live together and most especially, to grow as persons.â⬠Quality education is characterized as holistic where students are progressively initiated into their life-long challenge of harmonizing faith, culture and life. It provides educational programmes, curriculum contents, and teaching methods that meet the aspirations of students, parents and the community with regard to subject choices, career possibilities and educational needs of the community. It gives emphasis to educating students by teaching them through good examples and inculcating in them the importance of the craft of teaching and its support systems. Integrity of Creation ââ¬Å"Respect for the value of lifeâ⬠and ââ¬Å"care for the mother earthâ⬠are two major themes in valuing the integrity of creation. It upholds life-giving values and promotes stewardship of the earth. Culture Sensitivity Culture must be accepted as the gift of every people, the expression of their dignity, liberty and creativity, and the testimony of their unique place in the history of humanity. Culture sensitivity means openness and respect to the different culture of peoples. It promotes dialogue as a way of enhancing unity in diversity. On the individual level, it is a communication between two persons with different views, different values and traditions, to learn from each other in order for them to change and grow. Culture sensitivity as a value promotes respect for the tri-people of Mindanao, develops programs for inter-faith dialogue and upholds advocacy on issues as a result of the emerging culture of the global world.

Health Essays Power Empowertment Promotion
Health Essays Power Empowertment Promotion Power and empowerment in health promotion: Discuss the implications of power and empowerment in community based health promotion. Chronic disease is now a major concern for the western world. No longer are infectious and acute diseases the leading causes of death in the UK, but chronic diseases such as cancers and obesity related disorders have now taken over as the biggest health threats to the general population. Many chronic disorders are a result, to some degree, of behavioural factors like lifestyle choices or diet. Lung cancer from smoking and Type II Diabetes through poor diet (obesity) and sedentary lifestyle are prime examples of the link between modern life and a shift towards chronic disease. As a result of this partially behavioural foundation to illness, there is the opportunity to change open to many people, and ultimately the ability to improve health and health outcomes such as life expectancy or quality of life. Health can thus be seen to be potentially determined by our actions. One way of letting people know what they should be doing to stay healthy or to improve their health is through health promotion. As set out in the Ottawa Charter for Health Promotion (WHO, 1986), health promotion can be defined as the process of enabling people to increase control over, and to improve their health. To reach a state of complete physical, mental and social well-being, an individual or group must be able to identify and to realize aspirations, to satisfy needs, and to change or cope with the environment. The strategies used in health promotion programmes have been reported as diverse, through engaging in; awareness, information provision, influencing social policy, fighting for change and intervention type programmes. (Speller et al 1997) Traditionally health promotion has focused around education, prevention and protection interventions (Tannahill, 1985) and has been designed, implemented and evaluated from a top-down approaches and programmes. This is where behaviour change is generally the focus of outcome, and the issues that are being investigated are set by some form of authority, like a local health authority or even at a national level through the Government. Top down is thus where a small number of select people make the choices for people lower down the chain effectively a minority with power over the majority. Health promoters who operate in this capacity can thus be seen to hold and exert power over the population or different communities through their setting of the health promotion programmes, and through acting as gatekeepers of the information they choose to share. People in such decision-making positions may also have control over issues such as resource allocation and funding or who is given decision-making responsibilities (Laverack Laonte, 2000) and all of these factors work to take away power from the grass-roots / individual level. Real power is possessed by those who define the problem. (McKnight, 1999) Decision makers such as health promoters or authorities that dictate what people need, and what they can and cannot have in relation to health information, promotion and intervention also exert power over the population through creating individual dependency on health professionals for maintaining and responsibility for their health and wellbeing. The Ottawa Charter highlighted the need for health promotion to move beyond what is an essentially person-passive approach of receiving health promotion information and interventions, to one where individuals are enabled to become much more active participants with greater control over their health and well-being, and through instigating greater action on a community and group level. A concept known as empowerment with roots in social psychology constructs such as self-efficacy and health locus of control, refers to processes of social interaction of individuals and groups, which aim at enabling people to enhance their individual and collective skills and the scope and range of controlling their lives. (Erben, Franzkowiak Wenzel, 2000) Empowerment can thus occur at both individual and group levels, such as within communities. The basis of empowerment is essentially associated with the so-called bottom-up approach to health promotion (where the decision making process begins at the individual or group level, and these ideas are taken up the chain for approval and implementation) which has given focus to issues of concern to particular groups or individuals, and regards some improvement in their overall power or capacity as the important health outcome. (Laverack Labonte, 2000) Empowerment is seen as a particularly important strategy in enabling more marginalized groups of society, those who may be powerless in many other aspects of their lives as well as in regards to control over their health (Bergsma, 2004). The Ottawa Charter (WHO,1986) outlined the 8 fundamental pre-requisites it believed were necessary for attaining improvement in health and well-being; peace, shelter, education, food, income, a stable natural environment, sustainable resources, and lastly social justice and equity. People from marginalized groups or those who are from a lower socio-economic-status (SES) background may have the basics of these elements, but not in the quantities or to the levels of those from higher SES groups. Difficulties in these areas that are common amongst marginalized and low SES groups each in themselves have implications for health (Bergsma, 2004). Low income families are more likely to have an unhealthier and less nutritious diet. This is thought to stem from financial considerations of buying some foods, but may also be a consequence of poorer education. Low SES neighborhoods are also generally found to be more stressful places to live. Higher crime rates, poorer community facilities and educational institutions have the potential of confounding the problem further. Types of work amongst different SES groups can affect health some of the blue-collar jobs types associated with low SES groups are catergorised as some of the most stressful work environments; those with low control and low decision authority such as factory work are thought more stressful than typical white-collar jobs like managerial work. Stress is well established as linked to poorer health through work like PNI (psychoneuroimmunology) where psychological stress can be translated by the body into physiological responses and cause short-term and long-term health problems (Karasek, Baker, Marxer, Ahlborn Thorell, 1981) as well as psychological distress. As factors such as low income (money worries) crime rates (living in dangerous neighborhoods) and work all and feelings of powerlessness and have the potential to cause high levels of stress, those that are experiencing a good number of these factors are likely to have poorer health (Bergsma, 2004) than those who do not have such worries or uncontrollable stressors. These factors can thus be seen to be to a large extent, difficult to control, and as such people can feel powerless to make any changes in regards to such difficulties, either through feeling that they would be unable to make any change especially making change as a lone individual (Erben, Franzkowiak Wenzel, 2000) or where through education or poor health people are not aware of what changes could help them, or being in a position to take any action. It is for reasons such as these that research have found that change in knowledge did not necessarily translate into behaviour change through action, or ultimately improved health of those within health promotion education programmes. Health promotion at an individual level may thus not be effective for all individuals who come to the education or intervention with different experiences or backgrounds. Educational level may dictate the level to which people can understand health promotion campaigns or the medical reasons why they may need to alter their behaviour. Health education promotion may also be unable to interest everyone due to the different motivations for change that people may have someone who is struggling to pay the mortgage bills to keep their house may have less motivation to ensure they are eating healthily to make sure they do not develop diabetes. These individual differences in regards to health may exert a potentially large detrimental effect on the efficacy of health promotion programmes when decision making in regards to targeted behaviour, resource allocation etc, have been made without consultation with those the intervention is designed for, as is the case in typically top-down programming approaches. Some authors have however argued that top-down and bottom-up programmes for health promotion need not necessarily operate on a mutually exclusive basis. (Laverack Labonte, 2000) These authors argue that the way in which bottom-up approaches can be incorporated into top-down programmes is through more subtle targeting of behaviours for change. The example provided by Laverack Labonte (2000) is through concern more with the group members experiences of empowerment in terms of the quality of their social relationships and self-identities than with changes in specified health behaviours. Programmes with this focus may create an environment conducive to, and a support network for people to begin to critically evaluate their health behaviour. A study involving a sample of lower income women and their concerns about themselves (body image, parental ability, managing household budgets etc) found that within the supportive environment of the group, the women began to perceive they had more control over their situation and through this an increased feeling of self-esteem through which they began to evaluate health concerns such as smoking. (Labonte, 1996; Kort 1990) In this capacity health promoters and authorities can retain control of resources and project design, although the direction of the project will be guided by a need raised by the community. Greater priority is thus gained from understanding what a group or community needs through its participation in early stages, and not assuming what may be effective (Laverack Labonte, 2000). Through this kind of design stra tegy the powerless are becoming empowered to participate in the orientation and type of health promotion they receive. Empowerment within health promotion can thus be seen to involve enabling people to take more control over their health, through teaching them the skills they need to do this; developing self-efficacy (confidence in ones ability to perform / complete a task) decision making and problem solving skills, and life skills like communication, in general. Empowerment reestablishes the individual with autonomy over their health. (Hubley, 2002) Implications of empowering people on an individual level with their health, means that people have the chance to assess what is important to them, and to be in a position of making an informed choice about what they could do to improve or resolve their health problem, and to have the skills and knowledge of knowing where to start in the correction process if they come to the decision that they do want to change. Giving someone the capacity to make an informed choice over their health does not however guarantee that they will always make the same choices as health promoters or authorities may wish them to, simply that the power has been given back to them on deciding how to proceed. Empowered individuals may subsequently decide to give up drinking but continue smoking for example. There will be consequences of individual decisions at higher levels resulting from empowerment; those that continue to engage in unhealthy behaviours that have also received empowering health promotion interventions have used health promotion resources as well as potentially needing healthcare resources such as hospital stays, surgery or palliative care later on in their life as a result of behaviours they engage in. People may also experience guilt and psychological distress after making decisions that result in a poor health outcome, or may feel under stress from the responsibility of making choices that can affect their health. Those that through empowerment have taken positive action in regards to their health may reduce their future needs for resources from the health service, and may spread knowledge such as health dieting and exercise engagement with their family and friends. There are therefore both positive and negative implications for enabling people to take the driving seat in decision-making for their health. Western contemporary society does however favor the notion of personal control rather than state control, and this therefore is complimentary to the notion of health empowerment within the health promotion perspective. Personal empowerment can be complemented through community empowerment. This model from a bottom-up approach, takes into account the many social inequalities that exist within society, and the effect that such inequalities have on the health outcomes for minority / marginalized or low SES groups, and the extent to which they can bring about change in themselves and their situations socially. Community empowerment looks at re-establishing peoples power in relation to these factors at a social and community level that is theoretically proposed as benefiting health. A community can be defined as a geographical construct, but can also relate to a group of people who share a sense of social identity, common norms, values, goals and institutions. (Bergsma, 2004) The community empowerment construct seeks to help people develop these skills within small groups or communities, in order to allow them to be in a position to participate in the decision making process within their wider community, over issues that will affect their health and their lives and control over personal, social, economic and political forces in order to take action to improve their lives. (Israel et al, 1994) One way through which communities can do this is through participatory action research, which is when professionals work in collaboration with communities to define issues, designing the research questions gathering and evaluating the data, and designing resolutions to the problems investigated and finally in acting out the change required. (Gebbie, Rosenstock Hernandez, 2002) Action within a community setting towards health is one of the five principles that were outlined in the Ottawa Charter, as the WHO believed that people needed to hold some degree of control over their living and working conditions in order to develop lifestyles conducive to health, (WHO, 1986) as community empowerment health promotion allows individuals to gain mastery and impact the social, environmental ad economic conditions that determine their health (Bergsma, 2004). Implications of working from a community empowerment model within a bottom-up health promotion strategy, can be seen to be more informed decision makers within health authorities and those in charge of resource allocation, through being better informed about community level need through the use of local knowledge. Through this strategy a number of positive implications are potentially viable in comparison to tradition top-down programmes. Decisions based on local knowledge of need are likely to result in better health change and outcome as resources are more appropriately targeted with a better understanding of the people the services are aimed at. Closer collaboration between health authorities and communities is likely to create stronger collaborative relationships, which can create an environment of trust and openness. This has positive implications two ways, firstly through a more open relationship individuals within a community may more honestly assess their health behaviours and need through which authorities will be able to target resources even more efficiently. Within the community itself, collaborative work will continue to empower individuals allowing community participation to evolve to higher capabilities over time. On the more negative side, community empowerment initiatives that do not reflect the community perspective are likely to be construed as a waste of time by those who have participated, and this may cause distrust within the community towards health authorities and future health promotion initiatives, through the community disengaging with the health authority, health services, or future research, or resisting health promotion programmes. In summary, traditional top-down health promotion programmes can be seen to have operated in a way in which a minority had power over those which it aimed to help, through the control it exerted in regards to targeting health behaviours for change, resource allocation, information gate keeping, and dependency of health professionals to make decisions over individual health. This is compounded further for groups who are already marginalized within society, who have little control over other aspects of their living and working conditions, which have the potential to influence their health status power is associated with health to the extent to which those with the least power, have the poorest health. Bottom-up approaches to health promotion have begun to readdress the balance of power, through the use of empowerment strategies on both an individual and community level, in order to get people back involved (and capable) of making decisions about their health. It is found that empowerment on both these levels has a number of implications (positive and negative) for the individual and society in general, although it is felt that empowerment is more conducive to our notion of what society should be, and the power that individuals should have of making informed decisions over their own health.

Ultra High Temperature Ceramics for Thermal Protection
Ultra High Temperature Ceramics for Thermal Protection Recent Developments in Oxidation Resistance and Fracture Toughness of Ultra High Temperature Ceramics for Thermal Protection Systems Katrin Abrahams (Dated: February 3, 2015) For safer and faster space vehicles a reduction of the tipradius of the leading edges is inevitable. This leads to temperatures exceeding 2200 à °C which the used material has to withstand. ZrB2/SiC and HfB2/SiC have suitable properties, but the oxidation resistance and fracture toughness at high temperatures have to be improved. This review describes the recent approaches to handle these problems that base mainly on the addition of a third material (La2O3, Gd2O3 or graphite). The addition of either La2O3 or Gd2O3 led to increased oxidation resistance, but the processing, the amount of additive and the testing methods have to be improved. Due to the addition of graphite à ¯Ã ¬Ã¢â¬Å¡akes the fracture toughness of ZrB2/SiC (20 vol%) increased from 1. INTRODUCTION The Thermal Protection System (TPS) of space veà hicles is one of the most important parts of the whole vehicle [1ââ¬â3]. This protects it from the heating during re-entry. During this process the temperatures are very high, especially at the nose cone and leading edges as shown in Fig. 1. Figure 1: Temperature proà ¯Ã ¬Ã le of a space vehicle during reà entry prepared by the NASA. The dark red colour represents the highest temperatures and the light blue regions are coolest parts (copied from [4]). The tip of the leading edge has a radius of 10 cm, but a radius in the range of millimetres is wished so that sharp leading edges instead of blunt leading edges can be used [5]. This would have the advantage to ââ¬Å"help reduce the vehicles drag, enhance maneuverability and performance, and also improve safety due to an increased cross-range-capabilityâ⬠[5]. The problem of a smaller tip radius is that this leads to higher surface temperatures, which can exceed 2000 à °C [6, 7]. Jin et al. [8] investigated the maximum surface temperaà ture depending on the radius of the tip using an oxyacetyà lene torch. Fig. 2 shows that the temperature increases from 1930 à °C with a radius of 1.5 mm to 2100 à °C with the radius of 0.15 mm. Due to the high requirements for these materials only a few can be considered. Very good potential for the usage show Ultra high temperature ceramics (UHTC). These are ceramic materials with high melting points (> 3000 à °C), good thermal shock resistance and chemà ical and mechanical stability e.g. ZrB2, ZrC, HfB2 or HfC [6, 9, 10]. Although the carbides have a higher meltà ing point than the diborides, their thermal conductivity is lower, which is very important because the heat on the surface has to be transported as fast as possible away [5]. Therefore the main focus of research is on ZrB2 and HfB2. The problem with these diborides is their brittleness and their oxidation at temperatures exceeding 1200 à °C [11]. To fabricate a more ductile material SiC was added to ZrB2 or HfB2 [12]. Although ZrB2/SiC and HfB2/SiC are promising materià als for the usage in TPS, there are still two main problems which have to be solved. On the one hand side there is still the problem with the oxidation resistance at higher temperatures [11, 13]. On the other hand the fracture toughness decreases with the temperature to rather low values which also leads to mechanical problems [14]. This review gives an overview over solution attempts that have been made in the last years, with the main focus on ZrB2/SiC. 2. OXIDATION RESISTANCE The oxidation resistance of MeB2/SiC (Me = Zr, Hf) depends on the ratio of MeB2/SiC [10, 15], the presà sure [10, 16, 17], the temperature [18], the exposure time [19], on the processing [20, 21] and in case of the addition of additives also on their chemical structure and the amount of additive [22, 23]. Considering just ZrB2, the following happens during oxà idation [24]: The liquid B2O3 forms a protection layer for the porous ZrO2 layer, where oxygen can dià ¯Ã ¬Ã¢â ¬use very fast and easily through. But at 1100 à °C this protective layer evaporates and cannot prevent the oxidation of the bulk material anymore. The addition of SiC leads to the following additional reà actions [10, 25, 26]: During oxidation four dià ¯Ã ¬Ã¢â ¬erent layers can form (Fig. 3). Above the bulk material the SiC depleted zone forms, where SiC oxidizes to SiO2 which forms a borosilicate (BS) glass on the surface. This layer is porous due to the formation and evaporation of CO (Eq. (2)). Above this layer there is the oxidized layer, which consists of porous ZrO2 and the upper layer is the Silica rich layer which consist of the BS glass, that also à ¯Ã ¬Ã lls partly the pores of the ZrO2 layer. Due to the evaporation of B2O3, the protection layer is shrinking over time and shows an oxidation resistance up to 1600 à °C [24, 26]. In general the oxidation resistance is measured by the thickness of the reaction zone under the given parameters of the experiment. But also the dià ¯Ã ¬Ã¢â ¬usion coeà ¯Ã ¬Ãâcient of O2 is important but rarely measured. 2.1. Ratio ZrB2/SiC The dependency of the oxidation resistance on the raà tio of ZrB2/SiC was investigated by many researchers [10, 12, 15, 27ââ¬â29]. The addition of SiC led in all cases to a reà duction in grain size, a homogeneous distribution of SiC, higher viscosity and higher density. Karlsdottir et al. [29] investigated not only the reaction Figure 3: Schematic demonstration of the dià ¯Ã ¬Ã¢â ¬erent layers that form during oxidation of ZrB2/SiC and their arrangement. zone thickness but also the viscosity depending on the volume fraction of SiC. The results are shown in Table I and an increase in viscosity with the amount of SiC can be seen. This reduces the dià ¯Ã ¬Ã¢â ¬usion coeà ¯Ã ¬Ãâcient of O2 in the layer. Seong et al. [10] compared ZrB2, ZrB2/SiC (20 vol%), ZrB2/SiC (30 vol%) and ZrB2/SiC (40 vol%) and meaà sured the resulting thickness of the reaction zone. All samples were densià ¯Ã ¬Ã ed by hot pressing and exhibit a hoà mogeneous distribution of SiC. The grain sizes were beà tween 1.0 à µm and 3.0 à µm. They investigated the oxià dation under low and high pressure and the results are shown in Figure 4. The SiC depletion layer did not form and therefore the reaction zone consisted only of the Silica rich layer and the oxidized zone. In air (2âËâ"104 Pa) the thickness of the reaction zone was in ZrB2 the thickest due to the missing protecting silica layer and with increasing amount of SiC the thickness deà creases. The problem with high amounts of SiC (30 vol%) is, that it does not form single grains anymore, but inà stead a network, which leads to higher porosity. Under low pressure the behaviour is vice versa. Because the space shuttle has to deal with low and normal pressure ZrB2/SiC with 20 vol% or 30 vol% SiC is the best choice. Apart from the improvements of oxidation resistance due to optimization of the ZrB2/SiC ratio, at temperà atures above 1800 à °C active oxidation (Eq. (4)) of SiC takes place and this hinders the formation of the BS layer. 2.2. Additives To increase the oxidation resistance at higher temperà atures transition metals were added to the ZrB2/SiC maà trix [21, 30ââ¬â32]. They are suitable due to their high meltà ing points and low reactivity with the environment [30]. The transition metal cations can be enclosed in the BS layer to form a higher viscous layer that decreases O2 dià ¯Ã ¬Ã¢â ¬usion [11]. Furthermore this may lead to a higher evaporation point of the protective layer so that the maà terials are stable at T > 2000 à °C. This is based on an assumption, the mechanism how the transition cations interact with ZrB2 and SiC is not understood yet but in general a positive trend to higher oxidation resistance can be seen [11]. Several attempts were made with many dià ¯Ã ¬Ã¢â ¬erent transià tion metal oxides [9, 30], borides [11, 33], carbides [21, 31] and silicates [32]. This review focuses on La2O3 and Gd2O3 because they are the most promising additives and introduce two dià ¯Ã ¬Ã¢â ¬erent processing methods that efà fect the properties [30]. 2.2.1. Addition of La2O3 The addition of La2O3 to ZrB2/SiC was investigated by several researchers and led to dià ¯Ã ¬Ã¢â ¬erent results, espeà cially various new phases were found [6, 9, 22, 23]. Taà ble II gives an overview over the composition, the proà cessing routes to densify the material and the new phases that were discovered. Although Table II shows many dià ¯Ã ¬Ã¢â ¬erent results, genà eral trends due to the addition of La2O3 despite the usage of dià ¯Ã ¬Ã¢â ¬erent processing routes (hot pressing, spark plasma sintering (SPS)) were observed [6, 22, 23]: â⬠¢ Higher density Higher Vickers Hardness Reduction of grain sizes Besides the use of La2O3 leads to a more homogenized distribution of SiC, because it is always close to it and therefore prevents agglomeration [9]. In the case of fracture toughness there are contradictory statements: Li et al. [22] measured an increased fracture toughness compared to the material without additive and Guo et al. [23] published a lower fracture toughness due to the addition of La2O3. After hot pressing at 1900 à °C for 60 min Li et al. [22] disà covered the formation of new phases: La2Zr2O7 (melting point: 2295 à ± 10 à °C [9]) and La2Si2O7 due to the followà ing reactions: 2ZrO2(s)+ La2O3(s) ââ â La2Zr2O7(s) (5) 2SiO2(s)+ La2O3(s) ââ â La2Si2O7(s) (6) La2Zr2O7 was also observed by Zapata et al. [6] and Jayaseelan et al. [9] but no other working group detected the formation of La2Si2O7. The addition of 10 wt% La2O3, densià ¯Ã ¬Ã ed by SPS and oxidized for 1 h in air at 1600 à °C led to the formation of two dià ¯Ã ¬Ã¢â ¬erent oxidized layers [9]. On the surface a Laà BS-glass formed (Eq. (7)), below it two oxidized layers, one consisting of La2Zr2O7 (Eq. (5)) and the other one of ZrO2. SiO2 + La2O3 ââ â La âËâ BS âËâ glass (7) The large expansion coeà ¯Ã ¬Ãâcient of La2O3 causes à ¯Ã ¬Ã lling of the pores that appear after the evaporation of B2O3 and therefore still protects the bulk material. The same composition and the same processing was used by Guo et al. [23] but they could not detect the new phases. Instead they found out that La2O3 reacts Table II: Overview over the composition (always ZrB2/SiC (20 vol%) + the given amount La2O3), the processing route and the new phases that formed. amount La2O3 processing new phase 5 vol% hot pressing La2Zr2O7 (1900 à °C, 60 min) La2Si2O7 3 vol% hot pressing La2O3-SiO2 (1900 à °C, 60 min) 10 wt% SPS La2Zr2O7 oxidized (1600 à °C, 1 h, air) La-BS-glass 2 wt% SPS La2Zr2O7 oxidized (1400 à °C, 16 h, air) La-BS-glass with SiO2 to form La2O3-SiO2 as a protective layer. Further studies were made by Zapata et al. [6] who used less La2O3 (2 wt%). Due to the proximity of the La2O3 particles to the SiC particles they are also included in the BS melt whereby this results in a higher viscosity, a higher thermal stability and in general a better protecà tion against O2 dià ¯Ã ¬Ã¢â ¬usion. The oxidation tests show that at 1400 à °C the sample with La2O3 has a better oxidation resistance but at 1500 à °C and 1600 à °C it is worse. The reason is that because of the addition of La2O3 the BS layer has a higher viscosà ity and therefore the ZrO2 particles cannot precipitate directly to the top of the surface layer. This leads to a more homogeneous mixing with the BS melt. The oxyà gen dià ¯Ã ¬Ã¢â ¬usion through ZrO2 is much easier than through B2O3 and therefore a homogeneous distribution of ZrO2 makes it easier for O2 to dià ¯Ã ¬Ã¢â ¬use through this layer, alà though the La-BS-glass has a higher viscosity due to the addition of La2O3. Mo reover at 1600 à °C ZrOxCy and SiOxCy form with difà ferent O/C ratios which were found in the BS melt and in the oxide layer [6]. This can be seen as another proà tection layer because when O2 dià ¯Ã ¬Ã¢â ¬uses into the oxidation layer it will react with ZrOxCy or SiOxCy, so it can be seen as a puà ¯Ã ¬Ã¢â ¬er zone and it takes longer until the oxygen reaches the bulk material. HfB2 dià ¯Ã ¬Ã¢â ¬ers from ZrB2 because the formation of HfO2 is more dià ¯Ã ¬Ãâcult [6]. Therefore a smaller amount is formed which leads to a lower amount of B2O3 and therefore a thinner protection layer compared to ZrB2. But it has the advantage that the dià ¯Ã ¬Ã¢â ¬usion coeà ¯Ã ¬Ãâcient for O2 through HfO2 is smaller. Another problem in the case of HfB2 is that SiC is not as homogeneously distributed as in ZrB2 and it forms large agglomerates. When these agglomerates become oxidized they leave behind a highly porous material where O2 can easily dià ¯Ã ¬Ã¢â ¬use throug h. This shows that further improvements are inevitable in a more homogeneous distribution, further analysis of the new formed phases must be made and the C/O ratio can Figure 5: Topview (a) and sideview (b) of the surface with the dimensions of the cavities for Gd2O3. oxidation layer was 15 à ± 3 à µm and formed in accordance with the following reaction equation [9]: 2Gd2O3(s)+2ZrO2(s) ââ â Gd2Zr2O7(s) (8) Gd2O3(s)+ SiO2(s)+ B2O3(l) ââ â Gd âËâ BS âËâ glass (9) The thickness of the layer below it was 160 à µm and consisted mainly of porous ZrO2 due to the oxidation and evaporation of the glassy phase. The advantage of Gd-BS-glass compared to BS glass is the higher viscosity and therefore the reduced dià ¯Ã ¬Ã¢â ¬usion of O2 through this coating. At higher Gd2O3 fractions Gd stops ZrO2 particles at the glassy phase and they cannot dià ¯Ã ¬Ã¢â ¬use further. This leads to O2 vacancies which is the driving force for inward O2 dià ¯Ã ¬Ã¢â ¬usion. Using a distance of 20 à µm between the cavià ties, the Gd2O3 fraction is high enough to get a higher viscosity in the BS melt but ZrO2 can still precipitate so that no O2 inward dià ¯Ã ¬Ã¢â ¬usion occurs. 3. FRACTURE TOUGHNESS In 2009 the à ¯Ã ¬Ã rst tests were made to include graphite in the ZrB2/SiC matrix [34, 35]. Hu et al. [34] investigated the fraction of additive graphite to ZrB2/SiC (20 vol%). They found out that the addition of graphite led to a 1high dense material with an increasing fracture toughness be optimized. But the addition of La2O3 is already a from 4.5 MPam (ZrB2 + SiC (20 vol%)) to 6.1 MPam1 22 very promising approach for a better oxidation resistance although further research is necessary. 2.2.2. Addition of Gd2O3 For an improved surface and at the same time unà changed bulk material a new processing method was inà vented [11]: At à ¯Ã ¬Ã rst the sample was prepared and densià à ¯Ã ¬Ã ed using the bulk material ZrB2/SiC. Afterwards they used a laser to make equal sized cavities on the surface that were à ¯Ã ¬Ã lled with Gd2O3 nanopowder. The dimenà sions of the best sample can be seen in Fig. 5. Due to this new processing it was possible to create only a thin protection layer that consisted of BS mixed with Gd2O3 ( Eq. (9)). After 1 h in air under 1600 à °C the thickness of the outer (ZrB2 + SiC (20 vol% + graphite)). The dià ¯Ã ¬Ã¢â ¬erences beà tween 10 vol% and 15 vol% graphite were negligible small. Moreover there were investigations about the inà ¯Ã ¬Ã¢â¬Å¡uence of the diameter size of the graphite à ¯Ã ¬Ã¢â¬Å¡akes [36]. They found out that in the range of micrometres the diameter size does not change the fracture toughness. Asl et al. [14] used soft graphite nano-à ¯Ã ¬Ã¢â¬Å¡akes. They found out that ZrB2 + SiC (20 vol%) + graphite (10 vol%) showed a higher density than the samples without graphite. Furthermore the addition of graphite led to a decrease in grain size from 6.9 à µm to 3.2 à µm. The reason is the homogeneous distribution of graphite which stopped grain growth. Because of the reactions of graphite with the surface impurities the addition of graphite results in higher dense samples: ZrO2(s)+ B2O3(l)+5C(s) ââ â ZrB2(s)+5CO(g) (10) The particles that form due to this reactions can à ¯Ã ¬Ã ll the pores in the ZrB2/SiC matrix and therefore lead to a higher density. The resulting fracture toughness can be seen in Fig. 6. An increase in fracture toughness due to the addition of graphite is obvious. The following mechanisms led in this case to a higher fracture toughness: nano-à ¯Ã ¬Ã¢â¬Å¡akes pull-out, crack bridging, branching and deà ¯Ã ¬Ã¢â¬Å¡ection. 1 Figure 6: Fracture toughness depending on the composition of the sample at RT [14]. Wang et al. [37] investigated the dependency of the fracture toughness of ZrB2 + SiC (20 vol%) + 1 graphite (15 vol%) on the temperature in vacuum and in air (Fig. 7). Over the whole temperature range the fracture toughness in air was higher than that in vacà uum. In vacuum the fracture toughness decreases from This oxidation layer densià ¯Ã ¬Ã es with higher temperaà ture and yields in higher fracture toughnesses than withà out this layer. That is the reason why there is nearly no decrease in fracture toughness between 1200 à °C and 1300 à °C. Moreover crack deà ¯Ã ¬Ã¢â¬Å¡ection which absorbs the energy leads to higher fracture toughnesses at higher temperature. These mechanisms all result in a slower decrease in fracà ture toughness in air than in vacuum. Figure 7: Fracture toughness depending on the environment and on the temperature [37]. 4. CONCLUSION The recent developments to improve the oxidation reà sistance and the fracture toughness based mainly on the addition of a third component (La2O3, Gd2O3 or graphite). Concerning the oxidation resistance, the best matrix composition is ZrB2/SiC (20 vol%) because it shows the best oxidation protection over the whole range of O2 partial pressure. Above 1800 à °C active oxidation of SiC begins and oxidation resistance is not given anymore. at 1300 à °C because The approaches for a better oxidation resistance at higher ual thermal stresses between the ZrB2/SiC matrix and temperatures due to the addition of La2O3 or Gd2O3 arethe graphite inclusions are released. The residual stresses very promising, but more research to understand the real acted at low temperature as toughening mechanism and function of the additives and the interaction with the maà with the release of these stresses the fracture toughness trix is necessary. Furthermore there are many parameecreases. At 1300 à °C the group observed a brittle to ductile transà formation which leads to a slight increase of fracture toughness. But afterwards the fracture toughness deà creases further due to the distorted graphite and the larger ZrB2 grain sizes. In air at higher temperature the material starts to oxà idize and a oxidation layer forms on the surface due to ters that have to be optimized, e.g the amount of adà ditive, the processing route and especially the analytical approaches. Due to the varying experimental parameters and insuà ¯Ã ¬Ãâcient analytical tests it is dià ¯Ã ¬Ãâcult to compare results. To solve this problems standard tests have to be introduced and a wider temperature range for oxidation has to be investigated. The fracture toughness increased due to the addition of Eq. (1), (2) and the following reaction: graphite from 4.5 MPam to 7.1 MPam creases, but also this is slowed down due to the graphite tives, because extensive testing of the dià ¯Ã ¬Ã¢â ¬erent samples à ¯Ã ¬Ã¢â¬Å¡akes. is missing. Especially tests under real atmospheric and Taken into account the oxidation resistance and the frac-re-entry conditions are important but not done yet. ture toughness it is dià ¯Ã ¬Ãâcult to announce the best addiÃ

Sir Gawain and the Green Knight :: Essays Papers
Sir Gawain and the Green Knight Passage Analysis Sir Gawain and the Green Knight was written in the fourteenth century in Northern dialect by an anonymous author who was a contemporary of Chaucer. The story begins in King Arthur's court. The Green Knight, a green monster who challenges the court to a Christmas game, Sir Gawain, a brave, loyal knight of the court, and King Arthur, the lord of the court, are the main characters. Lines 279 through 365, which deal with the Christmas game, also known as the beheading game, foreshadow the Green Knight's supernatural powers, Sir Gawain's victory over the Green Knight, and his bravery and loyalty to King Arthur. The events surrounding the proposal of the game foreshadow what will happen next. It is New Year's, and everyone in King Arthur's court is feasting when the Green Knight arrives and challenges the court to a Christmas game. The rule of the game is that the knight, Sir Gawain, will strike at the Green Knight, and then in a year and a day, the Green Knight will return the strike. This is indicated when the Green Knight says, "â⬠¦So you grant me the guerdon to give him another, sans blame. In a twelve month and a day he shall of me the same"(Norton 208). A guerdon is a reward and sans means without. So when the Green Knight receives his reward for the game, which will be to return the strike in a year and a day, it will not be his fault when Sir Gawain dies because it is part of the game. This foreshadows the Green Knight's supernatural powers and Sir Gawain's confrontation with death. If Sir Gawain chops off the Green Knight's head, one would think that the Green Knight would die. So why does the Green Knight ask to meet Sir Gawain in a year and a day to return the strike? The answer to this question shows the Green Knight's supernatural powers because he knows that he is not going to die because of the strike. The Green Knight appears to have a hidden agenda, which will be revealed at the end of the story. As a reward for the knight who is brave enough to participate in the game, the Green Knight gives him his ax to keep and use for the game. The ax is first given to King Arthur, who has volunteered to participate in the game so that his court will not appear to be full of cowards.

Brain Development Essay -- Ancient History, Homo Erectus, Evolution
It is 400,000 years ago. A man sits in the mist of the jungle observing two rocks in his hands. Perplexed by their texture and strength, he strikes them together igniting a short spark. Amazed by the phenomenon he has created, he keeps striking the rocks until a huge spark ignites, not only burning his fingers, but setting the plants in front of him on fire. This man, classified as Homo erectus, has set the turning point to the human evolution. Neurobiologists and researchers claim that the discovery of fire has allowed humans to cook food, obtain warmth and protection, and increase over all human activity, all leading to the terrific growth of the human brain. Today, our brains have evolved so complexly that we are not only able to think and communicate, but believe and process both the transcendental and experiential aspects of religion. 500,000 thousand years ago, the hominid brain tripled in its size. Recent studies from Timothy Rowe at the University of Texas in Austin revealed that the first big increases in the brain size were in the olfactory bulb, suggesting that the early humans heavily relied on their noses, helping them sniff out food (Robson, 4). Through the use of fire, early humans were eating more nutritious food that in effect, helped grow their brains. Much of the brain's expansion took place in the neocortex. This part of the brain is involved in processing higher order cognitive functions that are connected with human religiosity. The neocortex is associated with self consciousness, language and emotion. According to Dunbar's theory, "the relative neocortex size of any species correlates with the level of social complexity of the particular species. The neocortex size correlates with social variables such as... ...opment of language, tools, and belief systems all lead to the ultimate creation of religion. Religions are practiced by over 90% of human beings on earth today. The feelings of connection people experience from religion are a function of neurochemistry. Rituals and social or religious gatherings act as serotonin factories to the brain, uplifting oneââ¬â¢s moods. Humans created religion to have hope and purpose in their lives when it was dark ad difficult. They wanted to find ways to strengthen their commitments when they felt adrift. Our brain has evolved over centuries, adjusting to circumstances, and growing rapidly to make us more complex beings. It has provided us with religion, giving us a sense of community when we felt isolated and alone. Our brain has provided with morals and principles that are impossible for us to outgrow today. After all, it made us humans!

Developmental Analysis Essay
Abstract The field of study that examines patterns of growth, change, and stability in behavior that occur throughout the entire lifespan is called lifespan development. Lifespan development takes a scientific approach in its study of growth, change, and stability. This development emphases on human development. Developmentalists study the course of development in nonhuman species, the most popular examine growth and change in people. In contrast I will focus on the ways people and myself change and grow during our lives, with the consideration of stability in our live span. Together, these findings suggest that we will go through different developments and stages from Infancy, through childhood and adolescence, and to marriage and parenthood. 11% of infants are born earlier than normal. Infants who are born prior to 38 weeks after conception is called preterm infants. When coming into this world I was born as a premature infant, I was born at 6 months due to my mother suffering from an illness called pneumonia. I was hospitalized for 4 months with tubes and monitors hooked up to me to help me eat, breathe and regain enough strength to go home to be with my family. Rupert (2006) discusses the prevention of premature birth, what you can do to prevent from having a premature baby. It is said that tension and stress can play a part and having a premature baby the less stress and tension on the body will prevent having a premature baby. Seeing a doctor regularly, taking prenatal pills, vitamins, eating healthy and making sure you have a good amount of rest can prevent premature birth as well. Being pregnant is a wonderful time for any women but it also require for you to be healthy as possible being pregnant can cause for you to go through a lot changing carrying a baby for nine months. Also, depending on your body you can go through more than otherà women when becoming pregnant, if you didnââ¬â¢t go through anything with your first child sometimes you can have some minor problems with your second child thatââ¬â¢s why it is important for you to take care of yourself when being pregnant. In my case I was my motherââ¬â¢s third child and coming down with an illness serious enough as pneumonia can be caused by stress and or from not taking care of yourself enough to remain healthy when pregnant. There are many factors on why prematurity will occur in women, rates of preterm births differ between racial groups, not because of race per se, but because members of racial minorities have disproportionately lower incomes and higher stress as a result Feldman (2014, p.95). Growing into the life cycles of infancy I stayed with my grandmother something I didnââ¬â¢t not find out until I was an adult. My mother expressed to me that she wasnââ¬â¢t able to care for me at the time because I was too small for her to feel comfortable caring for me at the time. When hearing this it did take me by surprise and hurt me a little only because I felt like she could have said something sooner than when it came out to me. I felt like there was a little detachment there because my mother wasnââ¬â¢t caring for me the first couple months I was born and/or when I was released from the hospital. Hotelling (2004) states not all parenting styles are alike. What individuals do as parents depends somewhat on how they were raised as a child, what they observed in other families, and what they have been taught. Two very different styles have emerged: Attachment Parenting and Baby wise. Parenting Oneââ¬â¢s own developed style of parenting will probably fall somewhere between the two. Attachment Parenting is a highly respected approach that promotes securely attached children. The problems with Baby wise Parenting, however, have been known to include detachment, behavioral disorders, dehydration, failure to thrive, irritability, infant anorexia, and even infant death (Hotelling, 2004).Parenting is never easy. Perspective parents are encouraged to seek out resources for support and information, starting now, to help ease the way. One thing is for sure: No recipe for parenting will guarantee a good nightââ¬â¢s sleep every night or perfect children (Hotelling, 2004). As stated in the article Bowlby (1982) defined attachment as a child being ââ¬Å"strongly disposed to seek proximity to and contact with a specific figure and to do so in certain situation, notably when he is frightened, tired or illâ⬠. Typically, preferred attachment emerges clearly in the latterà part of the 1st year of life, as evidenced by the appearance of separation protest and stranger wariness. Under usual conditions, preferred attachment unfolds gradually over the 1st year of life (Zeanah and Fox, 2004). Preferred attachments to caregivers may develop at any time after infants reach a cognitive age of 7 to 9 months, provided that the new caregivers have sufficient involvement with the child. Thus, young child ren adopted out of foster care or institutions readily form attachments to their new caregivers (Zeanah and Fox, 2004). Zeanah and Fox (2004) states there are four patterns of attachment, secure, avoidant, resistant, and disorganized have described individual differences in the organization of an infantââ¬â¢s attachment behaviors with respect to an attachment figure in this procedure. RAD was first introduced into the diagnostic nosologies just over 20 years ago, with the publication of the Diagnostic and Statistical Manual of Mental Disorders (3rd ed. [DSM-III], American Psychiatric Association, 1980).The criteria were substantially revised in DSM-I. The disorder is defined by aberrant social behavior that appears in early childhood and is evident cross-contextually. Two patterns have been described, an emotionally withdrawn ââ¬âinhibited pattern and an indiscriminately social ââ¬âdisinhibited pattern, each of which have been observed in children raised in institutions and in maltreated children (Zeanah and Fox, 2004). Growing into an adult after finding out that I wasnââ¬â¢t raised by my mother the first few months I felt some emotional distress, I felt from looking back on my childhood that there were some favoritism between me and my other brother and sisters. Feldman (2014) states developmentalists believe a true emotion has three components: a biological arousal component (such as increased breathing rate or heartbroken), a cognitive component (awareness of feeling anger or fear), and a behavioral component (displaying that one feels unhappy by crying, for example). Growing up my father was in my life after I came home from my grandmothers, but only for short amount of time. My father was abusive to my mother which caused for him to break up and get a divorce. After the divorce we didnââ¬â¢t really see our father that because of how abusive he could be and once he moved out he moved back to his hometown of New York, NY. We spoke occasionally on the phone and he even visited from time to time but as time went on the calling and the visiting stopped. It was very difficult to adjust to him not being there and not hearing from him the older me and myà brother and sisters got. Meyer (2010) discuss the influence of children on womenââ¬â¢s decisions to seek help when experiencing intimate partner violence. Intimate partner violence (IPV) has a detrimental effect on the wellbeing of victims and their children. Meyer (2010) states the role (unborn) children has been examined together with other demographic and situational factors to reveal their influence on victimsââ¬â¢ help-seeking decision. The two items were used to measure the role of children, including victimsââ¬â¢ pregnancy at the time of the abuse and children residing with the victim and witnessing the abuse. While the presence of unborn children (i.e., pregnancy) had no effect on victimsââ¬â¢ help-seeking decisions, children witnessing the abuse emerged as the strongest predictor of general and more formalized help ââ¬â seeking decisions. In conclusion, whil e the involvement of unborn children had no effect on victims help-seeking decisions, children who resided with the victim and directly witnessed the abuse had the largest effect on all examined help-seeking decisions. Seeing my mother abused at a child does take a piece of you and the reality if you will be yourself in the same situation when you get older to experience being an relationship yourself, also the fact of dealing with the fact that your father has been in and out of your life does cause emotional and physical damage. You can grow up with bitterness in your heart not willing to love or open yourself to feelings and emotions that will help you bond with others or make it hard for you to fall in love. As a child you learn how too really love from your parents but how to love another of the opposite sex you feel that emotion from your father as far relationships with other men. Wilcox (2012) argues is parent abuse a form of domestic violence, in this situation I would say there are many similarities between domestic violence and parent abuse since both entail a constellation of abusive behaviors embedded in the family relationship. In both cases, the majority of victims/survivors are fema les /mothers. Both involve a continuing process of social harm requiring day to day management. As with domestic violence, parent abuse involves everyday stresses which shape a parentââ¬â¢s ability to ââ¬Ëparent effectively ââ¬Ë. There are similarities but I would go as far to say same itââ¬â¢s a form of domestic violence because on the other hand had stated in the article, the parent has an ongoing responsibility to parent, versus making the option of ending or leaving the relationship inappropriate. If you have ever experienced loveà from your father how do you know how to love another man if your own father didnââ¬â¢t show you how a man is to love you? The role of the father in child development; parents donââ¬â¢t think having the father around while pregnant can affect the unborn child. As stated in this article studies investigating the role of the father in child development have focused on a range of different aspects of fathers and the father ââ¬â child relationship, such as paternal emotional well- being, father ââ¬â child attachment, and the quality of father ââ¬â child interactive. The study have shown that fathersââ¬â¢ active and regular engagement with their children has a positive effect on childrenââ¬â¢s social, behavioral, psychological, and cognitive development later in life. In conclusion this study was meant as an exploratory and preliminary investigation of fathers; experience during pregnancy Vreeswijk,M.J.M.,C., Maas,B.M.A.,J., Rijk,H.A.M.,C., Bakel ,V.J.A. H., (2013). Over the years as growing into an adult it has really been a struggle for me to maintain a healthy relationship with the opposite sex, because I am always questioning is this person who they say they are? Will they give up and leave and be abusive as my father was? Will I ever feel real love that I am wanting so badly to experience? As a young adult it was difficult to maintain a healthy longevity relationship or friendship, I would put more into the relationships and friendships and they would still end with my feeling being hurt because I was being so nice to gain and keep friends not knowing that it goes both ways it cannot be no one way street, when being in a relationship or friendship. I think this took me until I was almost 30 years of age to know that not everyone will treat you how you treat them. I was so naà ¯ve to think that everyone will treat you the way you treat them but a lot of people didnââ¬â¢t grow up that way. Every house hold is different and everyone is bor n into different lifestyles and parenting styles which causes them to react or act on what they seen as children growing up. Being an adult it is very challenging you see how your parents held the family together and what surfaces one has to take in order to take care of an family there are so many ups and downs you will go through when coming into adult hood. For me I was so excited being able to do things on my own without my parents but then reality really hit when I couldnââ¬â¢t lean on my parents anymore for things because they too was adjusting to being on their own again without caring for their children anymore. Today, at 32 it isà still a struggle as I am still growing into the women I was set out to be no one is perfect and it takes years for one to become fully mature and I know I will reach my potential success with growth, time, patience and having a healthy relationship with God. Some of the beliefs and I developed while growing up were in the Catholic Church. The Catholic Church is the Church that Jesus Christ established. Thus the Church subsists in the Catholic Church. However, member s of other Christian churches and denominations are also in communion with the Catholic Church by virtue of their sacraments. The accepted Churches possess fully valid sacraments, and are true particular Churches, whereas Christians are in communion with the Catholic Church on account of their baptism; still, this communion is impaired. The Church in one, because it is unified in Christ across regions. The Church is Holy on account of the grace of Christ given to it and the holy sacraments it provides. The Catholic Church contains the fullness of the Deposit of Faith, thus is it truly ââ¬Å"according to the wholeâ⬠and ââ¬Å"universal?â⬠Finally, the Church is Apostolic because its Teachings and power come from the Apostles themselves. Some of the beliefs I developed in the terms of right and wrong behavior were divorce, pre-marital sex, and same-sex relationships having a relationship with Christ always putting Christ and family first. The new Christian is capable of being a doer of the Word, enabled by the Spirit; then change in the problem areas can occur. I gather information to understand the problem and the underlying issues. We build a Christ-centered relationship of care and trust. 2 Timothy 3:16-17 (NIV) states encouragement from Godââ¬â¢s Word, outlining the certainty of being able to be equipped and strengthened to change with Godââ¬â¢s help. ââ¬Å"Spiritual development is likely a wellspring for the best of human life (e.g., generosity, unit, sacrifice, altruism, social justice) as well as for our darkest side (e.g., genocide, terrorism, slavery). Using social science to examine this potent force in society and individual lives of young people has been neglected for too longâ⬠(p. 210). The Handbook of Spiritual Development in Childhood and Adolescence seeks to ensure that this oversight does not persist. Spiritual development may be at a ââ¬Å"tipping pointâ⬠for becoming a major theme in child and adolescent development. A growing number of scholars in various disciplines have invested themselves in this field. The public imagination appears to be ready in numerous cultures, traditions,à and contexts, all of which are struggling with social changes that threaten to undermine the spiritual lives of young people.
