Youth and Religion: The Gameboy Generation Goes to Church

Using the secularization theory and the Marxist notion of religion as masking class conscience one would expect the importance of religion and religious involvement today to wane and be limited to lower class members. To challenge this expectation, using a representative national telephone survey of 2004 youth (ages 11–18) and their parents, we attempt to answer the following two questions: How religious are teenagers, and what may explain variation in religious perception and involvement among teens. Findings suggest that religion remains perceived as very important by most teenagers and parents report that about two-thirds of teenagers attended a place of worship at least monthly and that two out of five attended a social group sponsored by a religious organization. These findings do not support the secularization theory. As expected, parental attendance of religious worship, teen’s age, and teen’s ethnicity and gender were significantly associated with three variables of religious behavior and attendance. In contrast to the Marxist notion of religion, measures of socio-economic status indicate that, in the contemporary United States, religious participation, but not beliefs, is largely the domain of the middle-upper classes

Adolescent Risk Behaviors and Religion: Findings from a National Study

Too few studies have assessed the relationship between youth risk behaviors and religiosity using measures which captured the varied extent to which youth are engaged in religion. This study applied three measures of religiosity and risk behaviors. In addition, this study ascertained information about youths’ participation in religious activities from a parent or caretaker. Based on a national random sample of 2,004 teens (ages 11-18), this study indicates that youth perceive religion as important, are active in religious worship and activities, and further shows that perceived importance of religion as well as participation in religious activities are associated with decreased risk behaviors. Looking at ten risk behaviors, religiosity variables were consistently associated with reduced risk behaviors in the areas of: smoking, alcohol use, truancy, sexual activity, marijuana use, and depression. In the case of these six risk variables, religiosity variables were significantly associated with reduced risk behaviors when controlling for family background variables and self esteem. The study highlights the importance of further understanding the relationship between religious variables, background variables, self esteem, and youth risk behaviors

Single crystals of metal solid solutions

The following definitions were sought in the research on single crystals of metal solid solutions: (1) the influence of convection and/or gravity present during crystallization on the substructure of a metal solid solution; (2) the influence of a magnetic field applied during crystallization on the substructure of a metal solid solution; and (3) requirements for a space flight experiment to verify the results. Growth conditions for the selected silver-zinc alloy system are described, along with pertinent technical and experimental details of the project

Managing a non-profit hospitality platform conversion: The case of Couchsurfing.com

Couchsurfing (CS) was founded in 2003 as a non-profit for those interested in creating a common resource for world-wide hospitality exchange and low cost tourism. Built around a non-market communal sharing model, it became a for-profit in August 2011. Applying a discourse relational model approach, this study characterizes how competing discursive articulations over the conversion led to a discursive strategy of moral justification as management sought to retain its non-profit, alternative, democratic imaginary. The study finds that the justifications gained initial appeal, but ultimately lost credibility due to a mismanaged conversion. By articulating the competing discourses through the sacred value protection model (SVPM), this study provides insights into the way in which a management strategy can be interpreted at a micro-analysis level. It recommends that management decisions need to start from the activities of the organizations members, groups and networks so as to account for their emotions, motivations and actions

A critique of the revised Conflict Tactics Scales-2 (CTS-2)

The purpose of this review is to critically evaluate the Conflict Tactics Scales-2, a measure used worldwide for research and clinical practices. The reliability, validity and normative samples of the CTS-2 are considered and compared with similar psychometric measures. The limitations of the original CTS have been discussed alongside the CTS-2. Reliability is considered to be good to excellent by alpha coefficient and the variance explained by differing samples or methods of administration. Caution is recommended when interpreting the CTS-2 in clinical settings. Researchers point toward a five-factor structure to the CTS-2. The importance of appropriate norms is discussed and considered crucial when using the tool in settings where reporting patterns may differ. Difficulties in comparing CTS-2 scores across samples, cultures and countries are highlighted. Overall, the CTS-2 is a robust psychometric measure, although it holds limited clinical utility if it is used separately from other sources of information gathering (i.e. psychometric measures or interview). In order to enhance clinical utility, it should be administered alongside measures or clinical interviews that can provide added context regarding violence in the family. More research is required in diverse population samples, cultures/countries and languages

The Polarized Image of a Synchrotron-emitting Ring of Gas Orbiting a Black Hole

Abstract: Synchrotron radiation from hot gas near a black hole results in a polarized image. The image polarization is determined by effects including the orientation of the magnetic field in the emitting region, relativistic motion of the gas, strong gravitational lensing by the black hole, and parallel transport in the curved spacetime. We explore these effects using a simple model of an axisymmetric, equatorial accretion disk around a Schwarzschild black hole. By using an approximate expression for the null geodesics derived by Beloborodov and conservation of the Walker–Penrose constant, we provide analytic estimates for the image polarization. We test this model using currently favored general relativistic magnetohydrodynamic simulations of M87*, using ring parameters given by the simulations. For a subset of these with modest Faraday effects, we show that the ring model broadly reproduces the polarimetric image morphology. Our model also predicts the polarization evolution for compact flaring regions, such as those observed from Sgr A* with GRAVITY. With suitably chosen parameters, our simple model can reproduce the EVPA pattern and relative polarized intensity in Event Horizon Telescope images of M87*. Under the physically motivated assumption that the magnetic field trails the fluid velocity, this comparison is consistent with the clockwise rotation inferred from total intensity images
