Economic Hardship and Adolescent Problem Drinking: Family Processes as Mediating Influences

Alcohol is the most commonly used substance among adolescents in the United States, and adolescent drinking is associated with various health risk behaviors. Given the prevalence and consequences of adolescent drinking, understanding family factors that contribute to adolescent drinking is an important area for research. This study used three waves of data to evaluate a family stress model in which economic hardship is indirectly related to adolescent problem drinking through maternal psychological distress, parenting behaviors, and adolescent externalizing behaviors. Respondents included 300 mothers (71 % Black, 29 % White) and adolescents (51 % male) who were interviewed when adolescents were ages 10, 14, and 16. Structural equation modeling was used to test the hypothesized model and findings supported our hypothesized model. Economic hardship was positively related to maternal psychological distress. Maternal psychological distress was negatively associated with supportive parenting, which in turn was negatively associated with externalizing problems. Externalizing problems were positively associated with problem drinking. In support of our hypothesis regarding indirect effects, economic hardship was indirectly related to problem drinking through maternal psychological distress, parenting behaviors, and adolescent externalizing problems. The findings from this study highlight the role of family processes in adolescent problem drinking.     

Does border enforcement deter unauthorized immigration? The case of Mexican migration to the United States of America

This paper asks whether the migration decisions of unauthorized Mexican immigrants to the USA have been influenced by stronger US border enforcement efforts since 1993 that have sharply increased the physical risk and financial cost of illegal immigration. These measures were supposed to have decreased the probability of successful entry, thereby lowering the expected benefits of migration. We carried out a logistic regression analysis of data from a recent survey of 603 returned migrants and potential first‐time migrants in rural Mexico. Our findings indicate that tougher border controls have had remarkably little influence on the propensity to migrate illegally to the USA. Political restrictions on immigration are far outweighed by economic and family‐related incentives to migrate. An alternative, labor‐market approach to immigration control with higher probability of effectiveness is outlined.     

Democracy as Procedure and Democracy as Regime

In the intellectual confusion prevailing since the demise of Marxism and "marxism", the attempt is made to define democracy as a matter of pure procedure, explicitly avoiding and condemning any reference to substantive objectives. It can easily be shown, however, that the idea of a purely procedural "democracy" is incoherent and self-contradictory. No legal system whatsoever and no government can exist in the absence of substantive conditions which cannot be left to chance or to the workings of the "market" but must be posited as objectives of political activity. The confusion results from a deficient understanding of what makes a society and an empty idea of "freedom". The objective of politics is not happiness, an affair to be left to the individuals, but it certainly is liberty understood as participation in the governance of the polity; it is also the pursuit of the common good, defined as the sum of the prerequisites and facilitations of individual autonomy depending on collective action, and as the realization of commonly agreed collective goals.     

Clinical and forensic examinations of glycemic marker 1,5-anhydroglucitol by means of high performance liquid chromatography tandem mass spectrometry

Postmortem diagnosis of diabetes and a diabetic coma can be difficult because of the lack of characteristic morphological findings. 1,5-Anhydroglucitol (1,5-AG), the 1-deoxy form of glucose, competes with glucose for reabsorption in the kidneys. Therefore, diabetics with a permanent hyperglycemia show significantly lower serum concentrations of 1,5-AG than non-diabetics. A liquid chromatography-mass spectrometric method for the determination of 1,5-AG in serum and postmortem blood was developed and validated according to international guidelines. Linearity was given between 1μg/ml and 50μg/ml. Recovery rates ranged between 70.8% and 89.8%, the limit of quantification of the procedure was 0.20μg/ml, limit of quantification was 0.55μg/ml. Serum of 199 diabetics and 116 non-diabetics and femoral blood of 31 diabetic and 27 non-diabetic deceased was measured. Average concentrations were significantly (p<0.001) higher in non-diabetics compared to diabetics ante and postmortem. Seven of the diabetics may have died because of a hyperglycemic coma indicated by a sum formula of Traub>450mg/dl. 1,5-AG average concentrations in these deceased were not significantly different to diabetics which did not die because of a diabetic coma. Concentrations of 1,5-AG give a hint for not well controlled diabetes antemortem and postmortem and can be assumed as an additional and alternative information postmortem to the measurement of HbA1c or fructosamine.     

Pubertal Timing and Early Sexual Intercourse in the Offspring of Teenage Mothers

Early puberty is associated with stressful family environments, early sexual intercourse, and teenage pregnancy. We examined pubertal timing and sexual debut among the 14-year-old offspring of teenage mothers. Mothers (71% Black, 29% White) were recruited as pregnant teenagers (12–18 years old). Data were collected during pregnancy and when offspring were 6, 10 and 14 years old (n = 318). Adolescents (50% male) compared the timing of their pubertal maturation to same-sex peers. There was a significant 3-way interaction effect of race, sex, and pubertal timing on sexual debut (n = 305). This effect remained significant in a model controlling for maternal age at first intercourse, substance use, exposure to trauma, authoritative parenting, and peer sexual activity (n = 255). Early maturation was associated with early sex in daughters, and may be one pathway for the inter-generational transfer of risk for teenage pregnancy among daughters of teenage mothers.     

Full STR profile of a 67-year-old bone found in a fresh water lake

DNA extraction from and DNA typing of fresh water-exposed aged bone specimens poses a challenging task and is not very well examined. This study presents a new method to extract typable DNA from such problematic bone specimens. The procedure comprises low-heat drilling and cryogrinding, mild lysis conditions, and silica-column-based DNA cleaning. DNA quantity is assessed by quantitative PCR prior to short tandem repeat (STR) amplification. The procedure was employed with a 67-year-old tibia bone fragment recovered from a fresh water lake and succeeded to produce a full STR profile using the MPX-SP1 and MPX-SP2 mini-STR kits and a partial profile with 12 successfully amplified STRs using the Identifiler STR kit. The new method for the extraction of DNA from aged fresh water-exposed bone specimens presented herein was successfully applied to prepare DNA of sufficient quality and quantity to generate a full STR profile.     

Self-Reported Communication Variables and Dating Violence: Using Gottman’s Marital Communication Conceptualization

Communication behaviors, while extensively studied within the marital field, have received only peripheral attention in violent dating relationships. The purpose of this research was to better establish empirical continuity between the marital and dating literatures by exploring communication variables that have been identified in marital relationships broadly and their self-reported manifestation in violent dating relationships. Using Gottman’s (1999) marital communication conceptualization, individuals were assessed on adaptive and maladaptive communication variables and relationship aggression. Results suggested that negative communication behaviors were associated with, and predicted, aggression in participants’ dating relationships, consistent with findings from the marital literature. However, repair attempts, generally considered an adaptive communication behavior, predicted aggression victimization. Implications and how these data fit within the context of recent research on positive marital communication behaviors are explored.     

Using the personal influence model to guide theory building for participatory communication in Africa

Abstract

This article argues that the personal influence model (PIM) be used strategically to resolve conflicts and social crises in Africa. It presents PIM as a complementary, analytic discourse to participatory communication, a development paradigm commonly used globally in a variety of social programs. That discourse, as a framework for theory building, is grounded in Africa's emerging and enduring realities: (a) the growing interest of the international community to assist Africa to meet the U.N. Millennium Development Goals, whose focus is to reduce extreme poverty by 2015; (b) the ephemeral nature of Africa's political and social stability that necessitates reducing fear, improving community security, nurturing public trust, and building inter-group relationships, all as preconditions for attaining social development, and for using a community-agency- contracts-partnerships approach to deliver development services; and (c) the palpable congruence of PIM with Africa's extensive social networks, which are typically used as communication tools for social development. Those realities guide four propositions that serve as a heuristic template for testing and refining the participatory approach, thereby guiding theory building in participatory communication in African communities. That template identifies an expansive three-concept research agenda – culture, community governance and rule of law, and economic freedom – that raises questions, defines concepts, measures key variables, and assesses outcomes.
