The phoenix population: Demographic crisis and rebound in Cambodia

The study of mortality crises provides an unusual and valuable perspective on the relationship between mortality and fertility changes, a relationship that has puzzled demographers for decades. In this article, we combine nationally representative survey and demographic-surveillance system data to study fertility trends around the time of the Khmer Rouge (KR) regime, under which 25% of the Cambodian population died. We present the first quantitative evidence to date that attests to a one-third decline of fertility during this regime, followed by a substantial "baby boom" after the fall of the KR. Further analyses reveal that the fertility rebound was produced not only by a two-year marriage bubble but also by a surge in marital fertility that remained for nearly a decade above its precrisis level. Our results illustrate the potential influence of mortality on fertility, which may be more difficult to identify for more gradual mortality declines. To the extent that until recently, Cambodian fertility appears to fit natural fertility patterns, our findings also reinforce recent qualifications about the meaning of this core paradigm of demographic analysis.     

Diversity and change in Cambodian households, 1998–2006

Extant ethnographic studies suggest that the nuclear family has been the predominant living arrangement in Cambodia, and the country’s rapid socioeconomic transformation since the early 1990s may have accentuated that dominance. To examine these claims, we analyse here household structure in Cambodia between 1998 and 2006, based on data from the 1998 Census, two nationally-representative surveys (2000 and 2005), and a continuing demographic surveillance system (from 2000 on). Our analysis confirms the large prevalence of nuclear families, but not an unequivocal trend toward their increasing prevalence. First, nuclear families are less prevalent in urban than in rural areas, and nationwide, they appear to have receded slightly between 2000 and 2005. We find that increases in the prevalence of extended households correspond to periods of faster economic growth, and interpret these contrasted trends as signs of tensions during this transitional period in Cambodia. While the nuclear family may still be the cultural norm, a high degree of pragmatism is also evident in the acceptance of other living arrangements, albeit temporary, as required by economic opportunities and housing shortage in urban areas.     

Stress,Depression, and Drug Use Among Aging Mexican American Men Living in the Barrio

Residing in Mexican American barrios might place individuals at heightened risk for chronic financial and acute stress, which are associated with adverse mental health outcomes. Stressors could be exacerbated for substance users. This research explores relations between chronic financial stress, acute stress, and depressive symptomatology among aging Mexican American heroin and other drug-using men. A prospective cohort study and field-intensive outreach methodology were used to recruit 227 men for in-depth interviews. Participants were categorized into depressed and nondepressed groups based on symptomatology measured by the Center for Epidemiological Studies Depression Scale. Chronic financial stress (i.e., poverty) and acute stress (i.e., Life Events Questionnaire) associated with depressive symptomatology were tested using logistic regression. Findings suggest scores of depressive symptoms among substance users are highly related to chronic financial stress. Community-level interventions targeting chronic stressors present in the barrio could be especially salient in improving the mental health of Latino drug users.     

Barossa Night: cohesion in the British Army officer corps

Contrasting the classical explanation of military group cohesion as sustained by interpersonal bonds, recent scholars have highlighted the importance of ritualized communication, training and drills in explaining effective military performance in professional armies. While this has offered a welcome addition to the cohesion literature and a novel micro‐sociological method of examining cohesion, its primary evidential base has been combat groups. Indeed, despite their prominent role in directing operations over the past decade, the British Army's officer corps has received relatively little attention from sociologists during this period. No attempt has been made to explain cohesion in the officer corps. Using a similar method to recent cohesion scholars, this paper seeks to address this imbalance by undertaking a micro‐sociology of one ritual in particular: ‘Barossa Night’ in the Royal Irish Regiment. Firstly, it draws on the work of Durkheim to examine how cohesion amongst the officer corps is created and sustained through a dense array of practises during formal social rituals. It provides evidence that the use of rituals highlights that social solidarity is central to understanding officer cohesion. Secondly, following Hockey's work on how private soldiers negotiate order, the paper shows how this solidarity in the officer corps is based on a degree of negotiated order and the need to release organizational tensions inherent in a strictly hierarchical rank structure. It highlights how the awarding of gallantry medals can threaten this negotiated order and fuel deviancy. In examining this behaviour, the paper shows that even amongst an officer class traditionally viewed as the elite upholders of organizational discipline, the negotiation of rank and hierarchy can be fluid. How deviant behaviour is later accepted and normalized by senior officers indicates that negotiated order is as important to understanding cohesion in the British Army's officer corps as it is amongst private soldiers.     

Time preferences and consumer behavior

We investigate the predictive power of survey-elicited time preferences. The discount factor elicited from choice experiments using real payments predicts various health, energy, and financial outcomes, including overall self-reported health, smoking, installing energy-efficient lighting, and credit card balance. Allowing for time-inconsistent preferences, both the long-run and present-bias discount factors (δ and β) are also significantly associated in the expected direction with several outcomes. We consider several hypotheses regarding the strength of the association between discount factors and outcomes, such as salience of the outcome or liquidity constraints.     

Romancing the nation,effacing history: reading Kenya through patriotic choral music

This article looks at music as one of the channels used by oppressive regimes to persuade the public to pledge loyalty to the nation and government of the day while at the same time blinding citizens from acknowledging the social, economic and political realities on the ground. Music composed, performed and accompanied by dance and visual images, and subsequently broadcast through different media channels, can be effective in achieving this mission. This article examines the song Tuishangilie Kenya (1984, revised 2012) as an example of the way music and performance in the Kenyan context become tools to efface substantial historical realities in order to project an imagined vision of a united nation. This article draws on Stuart Hall’s argument that music channelled through mass media can instil a sense of patriotism and national consciousness, and Nicholas Cook’s analysis of music in television commercials, to argue that the 2012 remaking of Tuishangilie Kenya provides a potential avenue for constructing a kind of double meaning, one overtly intended and one subverted at the end. Through an analysis of the song’s lyrical, musical and visual parameters I demonstrate how the audience is “hoodwinked” but how propaganda can backfire.     

EM algorithm-based likelihood estimation for a generalized Gompertz regression model in presence of survival data with long-term survivors: an application to uterine cervical cancer data

In this paper we develop a regression model for survival data in the presence of long-term survivors based on the generalized Gompertz distribution introduced by El-Gohary et al. [The generalized Gompertz distribution. Appl Math Model. 2013;37:13–24] in a defective version. This model includes as special case the Gompertz cure rate model proposed by Gieser et al. [Modelling cure rates using the Gompertz model with covariate information. Stat Med. 1998;17:831–839]. Next, an expectation maximization algorithm is then developed for determining the maximum likelihood estimates (MLEs) of the parameters of the model. In addition, we discuss the construction of confidence intervals for the parameters using the asymptotic distributions of the MLEs and the parametric bootstrap method, and assess their performance through a Monte Carlo simulation study. Finally, the proposed methodology was applied to a database on uterine cervical cancer.     

Training users to counteract phishing

Phishing is an increasingly more prevalent form of online, social engineered scams that escalate costs and risks to society year to year. This study demonstrates an association between anti-phishing training techniques used in previous research and individual differences which could affect phishing susceptibility. Results indicated that anti-phishing training in both a simple comic and more complex video game form is helpful in decreasing phishing susceptibility as measured by Miss rates for all individuals including college aged and computer savvy participants. Based on the results of the present study, implications for future efforts to combat phishing are discussed.
