Purpose – In order to study how religious behaviour is evolving in contemporary societies, the chapter looks at the relation between the individuals' position in social stratification and their participation to the weekly mass, and at its evolution in contemporary Italy.

Design/Methodology/Approach – The data come from the Italian National Election Study (ITANES) database, including national representative surveys from 1968 to 2006, and are analyzed with logit models.

Findings – Weekly mass participation has decreased from 1968 to 2006. The trend was rapid in the 1960s and 1970s, has slowed in the 1980s, but it has started again in the 1990s. Ceteris paribus, the upper class, shows a consistently more religious behaviour than the intermediate and the lower ones, and that the least educated are more religious. There is also evidence of a strong and consistent cohort effect, persisting across the considered period. Each cohort does not change much its participation to the weekly mass over time, but each new cohort shows a lower level of participation.

Research limitations/Implications – The findings give support to the classical secularization thesis, despite the many critiques addressed to it since the 1990s. Given that Italy is one of the most religious Western countries, this is a quite important finding. Some support is also given to the hypothesis of religion as an ‘instrumentum regni’, according to which it is in the interest of the higher social strata to be more religious, as religion supports and legitimates existing patterns of social inequality. Findings concerning cohorts point to socialization as the actual mechanism changing behaviours and attitudes.

Acts of mass violence are not a new phenomenon in the United States. Law enforcement and homeland security officials prepare, prevent, respond, investigate, and assist in prosecuting offenders in these events. How then can the greater homeland security community effectively avert future acts of mass violence with its even broader mission set? Physical and technological security countermeasures are not enough to prevent these types of incidents from occurring. The purpose of this chapter is to briefly give an overview of some of the research into the indicators and traits exhibited by perpetrators of mass violence and the best practices that have evolved to intervene as a result. Recognizing the common traits and behaviors displayed by past attackers, their surrounding influences and the common traumas most of them have experienced, is an essential first step in developing effective strategies to prevent acts of mass violence.

Past studies have shown wide variation in the obesity rates of Asian American ethnic subgroups. However, whether weight-related behaviors that occur during acculturation are associated with obesity disparities among Asian American ethnic subgroups is unknown. This study examines the differences in body mass index (BMI) across Asian American ethnic subgroups and assesses how acculturation and weight-related behaviors influence these differences. The linear regression models employed in this study use data pools from 2011 to 2014 released by the California Health Interview Survey (CHIS). The sample comprises 3,248 foreign-born Asian Americans aged 18–59 years. Asian Americans who spoke fluent English had significantly lower BMIs than those who spoke poor English, but English fluency did not explain body size disparities among Asian American ethnic subgroups. Filipino Americans had the highest average BMI (25.89 kg/m²) and obesity rate (53.12%), and they were particularly prone to engage in unhealthy weight-related behaviors, such as consuming fast food, drinking soda, and engaging in sedentary lifestyles. However, weight-related behaviors did not explain their high risk of obesity compared to other Asian American ethnic subgroups. The results underscore the potential for misinterpretation when pan-ethnic labels, such as Asian American, collapse the unique experiences of different immigrant origin groups. Future research may investigate whether other factors that affect the acculturation process, such as attitudes, self-identity, beliefs, or experiences with racism and discrimination, explain obesity disparities among Asian American ethnic subgroups.

Various mass shooters have explained their violent actions as a response to failing at dominant forms of masculinity, including rejection from women and negative social comparisons to other men. The affect control theory of self (ACT-Self) posits that interactions that violate one's sense of self cause inauthenticity. This disequilibrium motivates behaviors that restore self-meanings, which may partially explain the link between challenges to the self and compensatory violence.

In Study 1, we use ACT-Self to examine the relationship between inauthenticity, violent fantasies, and physical aggression in the autobiography of one mass shooter. We quantify self-sentiments and inauthenticity using ACT-Self measures and methods, and perform a thematic analysis of the shooter's interpretations of and responses to disconfirming events. In Study 2, we examine the relationship between these same concepts in a survey of 18-to-32-year-old men (N = 847).

Study 1 shows that the shooter's inability to achieve popularity, wealth, sex, and relationships with beautiful women (compared to other men) produced inauthenticity that he resolved through violent fantasies, increasingly aggressive behavior, and ultimately, mass violence. Study 2 finds that inauthenticity arising from reflected appraisals from women predicts self-reported violent fantasies and physical aggression in a convenience sample of men in emerging adulthood.

This work leverages a formal social psychological theory to examine the link between self-processes and violence. Our findings suggest that men's inauthenticity, particularly produced by reflected appraisals from women, is positively associated with violent fantasies and acts. Further work is needed to assess whether this relationship is causal and for whom.

Independent travelers are those vacationers who have booked only a minimum of their transportation and accommodation arrangements prior to departure on the vacation. Independent travel is an important and growing sector of worldwide tourism. Choice of vacation itinerary for the independent vacation represents a complex series of decisions regarding purchase of multiple leisure and tourism services. This chapter builds and tests a model of independent traveler decision-making for choice of vacation itinerary. The research undertaken employs a two-phase, inductive–deductive case study design. In the deductive phase, the researcher interviewed 20 travel parties vacationing in New Zealand for the first time. The researcher interviewed respondents at both the beginning and the end of their New Zealand vacations. The study compares pre-vacation research and plans, and actual vacation behaviors, on a case-by-case basis. The study examines case study narratives and quantitative measures of crucial variables. The study tests two competing models of independent traveler decision-making, using a pattern-matching procedure. This embedded research design results in high multi-source, multi-method validity for the supported model. The model of the Independent Vacation as Evolving Itinerary suggests that much of the vacation itinerary experienced in independent travel is indeed unplanned, and that a desire to experience the unplanned is a key hedonic motive for independent travel. Rather than following a fixed itinerary, the itinerary of an independent vacation evolves as the vacation proceeds. The independent traveler takes advantage of serendipitous opportunities to experience a number of locations, attractions and activities that they had neither actively researched nor planned.

This chapter examines possible relationships between use of social media in online mobilization and mainstream print media coverage during the June 2013 protests in Brazil, a series of demonstrations which happened throughout the country initially around bus ticket prices.

In order to develop the research, we compared news from leading Brazilian newspapers (O Globo, Folha de S. Paulo, Estadão, and O Dia) with the activities of most influential Twitter users in the dissemination of messages about these events in the country during the period from June 01 to 30, 2013. The results show trends in the emerging dynamics of social organization that may indicate the role of old and new media in today’s Brazilian politics.

The research analyzed the extent to which the events occurring on the streets shaped and/or reflected user-generated social media content.

This chapter examines the role mass media plays in the maintenance of social control and policy formulation and implementation in the Trump political era. First, an historical survey of mass media theory is presented and used as an analytic lens through which to identify that mass media has long been recognized as a powerful tool of social control or disruption and in public policy formulation and implementation. Second, this chapter explores the challenges posed to society and policy when a president uses mass media to spread misinformation and disinformation. Third, this chapter identifies the divisive nature of US political attitudes in the Trump era and how social media contributes to cleavage. Fourth, this chapter explores efforts by foreign actors, particularly Russian, to spread discursive and thus social chaos through disinformation campaigns in the United States and other western democracies. This chapter concludes that mass media has been both a divisive and uniting force, although the rise of social media and its susceptibility to manipulation poses a danger to social cohesion and effective public policy formulation and implementation. These factors have contributed to civil divisiveness and lack of policy clarity.

Using a framework based on dimensions of economic theory and behavioral sciences for understanding and mass market versus individual customers as the unit of analysis, this article looks at the development of marketing theory primarily during the last century. It looks at the common goal of understanding markets and their functioning as well as the differences in attaining this goal imposed by the very nature of the economic of behavioral foundations brought to bear on the problem. The paper concludes with the observation that, while we have come a long way toward reaching the goal, we have a long way to go to complete the journey.
