Quality of Life,Hegemony, and Social Change in Rural Ireland: W. Bence Jones, 'A Landlord Who Tried to do His Duty'

Numerical indexes of quality of lifeprovide a date-specific representation of society, and a time series extends our grasp of events. However, the social processesundergirding date-specific indexes and therelated intervals in time fail to convey therealities of the human experience. Indicesabstract meaning from events and the people whoparticipate in them.Quality of life can rise and fall, and maymove in both directions in a lifetime. Withinthose processes some people are agents ofchange, a status derived from social positionand wealth. The retrospective appraisal of hisexperiences as a resident landlord is used as aschema for an appraisal of William Bence Jones'role in the evolving quality of life inVictorian Ireland.     

“Feeling Warmth and Close to Her”: Communication and Resilience Reflected in Turning Points in Positive Adult Stepchild–Stepparent Relationships

With the goal of understanding the development of positive stepchild–stepparent relationships, the researchers focused on turning points characterizing the interaction of adult stepchildren who have a positive bond with a stepparent. Engaging a relational turning points perspective, 38 stepchildren (males and females, ages 25 to 52 years old) who reported a positive stepparent relationship were interviewed, generating 269 turning points which were categorized into 15 turning point types and coded by valence. Turning points occurring most frequently were: prosocial actions, quality time, conflict/disagreement, changes in household/family composition, and rituals. Findings are discussed, including implications for developing and enacting resilient and positive stepchild–stepparent relationships and future directions for researchers wanting to focus on positive family interaction.     

Individual Actual or Perceived Property Flood Risk: Did it Predict Evacuation from Hurricane Isabel in North Carolina, 2003?

Individual perception of risk has consistently been considered an important determinant of hurricane evacuation in published studies and reviews. Adequate risk assessment is informed by environmental and social cues, as well as evacuation intentions and past disaster experience. This cross‐sectional study measured perceived flood risk of 570 residents of three coastal North Carolina counties, compared their perception with actual risk determined by updated flood plain maps, and determined if either was associated with evacuation from Hurricane Isabel in 2003. Census blocks were stratified by flood zone and 30 census blocks were randomly selected from each flood zone. Seven interviews were conducted at random locations within selected blocks. Bivariate and multivariable analyses were conducted to produce crude and adjusted risk differences. Neither the designated flood zone of the parcel where the home was located nor the residents' perceived flood risk was associated with evacuation from Hurricane Isabel in the bivariate analysis. In the multivariable analysis, intention to evacuate and home type were important confounders of the association between actual risk and evacuation. The belief that one is at high risk of property damage or injury is important in evacuation decision making. However, in this study, while coastal residents' perceived risk of flooding was correlated with their actual flood risk, neither was associated with evacuation. These findings provide important opportunities for education and intervention by policymakers and authorities to improve hurricane evacuation rates and raise flood risk awareness.     

Intergenerational Profiles of Socioeconomic (Dis)advantage and Obesity During the Transition to Adulthood

Investigations of socioeconomic status (SES) and health during the transition to adulthood in the United States are complicated by the later and more varied transitions in residence, employment, schooling, and social roles compared with previous generations. Parental SES is an important influence during adolescence but cannot sufficiently capture the SES of the independent young adult. Typical, single SES indicators based on income or education likely misclassify the SES of young adults who have not yet completed their education or other training, or who have entered the labor force early with ultimately lower status attainment. We use a latent class analysis (LCA) framework to characterize five intergenerational SES groups, combining multidimensional SES information from two time points—that is, adolescent (parental) and young adult (self) SES data. Associations of these groups with obesity, a high-risk health outcome in young adults, revealed nuanced relationships not seen using traditional intergenerational SES measures. In males, for example, a middle-class upbringing in adolescence and continued material advantage into adulthood was associated with nearly as high obesity as a working poor upbringing and early, detrimental transitions. This intergenerational typology of early SES exposure facilitates understanding of SES and health during young adulthood.     

Non‐governmental organisations and informal associations in service delivery for African migrants in China: Evidence of voluntary sector failure?

As the Chinese government has purposefully built economic, social and political links with several African states in recent decades, new patterns of international migration have emerged. Notably, mixed‐race families are increasingly visible in southern China, particularly Guangzhou, where there is a concentration of African traders. The few existing studies on this population have failed to pay attention to how, in the absence of state provision of or support for key public resources including health care and education, African‐Chinese families are raising their children. We examined factors contributing to NGO successes and failures in facilitating these families’ wellbeing and integration into mainstream society, drawing on the theory of voluntary sector failure. Mixed‐raced families are relatively isolated from mainstream society as well as formal/informal civil society organisations. We found select features of philanthropic paternalism, philanthropic amateurism, and what we term philanthropic mistrust, with implications for understanding voluntary sector growth in the Chinese context.     

Analytic bounds on causal risk differences in directed acyclic graphs involving three observed binary variables

We apply a linear programming approach which uses the causal risk difference (R_DC)$(R{D}_C)$ as the objective function and provides minimum and maximum values that R_DC$R{D}_C$ can achieve under any set of linear constraints on the potential response type distribution. We consider two scenarios involving binary exposure X, covariate Z and outcome Y. In the first, Z is not affected by X, and is a potential confounder of the causal effect of X on Y. In the second, Z is affected by X and intermediate in the causal pathway between X and Y. For each scenario we consider various linear constraints corresponding to the presence or absence of arcs in the associated directed acyclic graph (DAG), monotonicity assumptions, and presence or absence of additive-scale interactions. We also estimate Z-stratum-specific bounds when Z is a potential effect measure modifier and bounds for both controlled and natural direct effects when Z is affected by X  . In the absence of any additional constraints deriving from background knowledge, the well-known bounds on R_Dc$R{D}_c$ are duplicated: -Pr(Y≠X)?R_DC?Pr(Y=X)$-\mathit{Pr}(Y\ne X)?R{D}_C?\mathit{Pr}(Y=X)$. These bounds have unit width, but can be narrowed by background knowledge-based assumptions. We provide and compare bounds and bound widths for various combinations of assumptions in the two scenarios and apply these bounds to real data from two studies.     

A Comparative Analysis of the Relative Effectiveness of Four Dynamic Lot-Sizing Techniques on Return on Investment

The relative performance of dynamic lot-sizing techniques has been of considerable interest to researchers in recent years. While research has addressed performance in terms of cost-effectiveness, researchers have not determined the impact of dynamic lot-sizing techniques on return on investment (ROI) as it applies to finished goods' schedules. The purpose of this research is to explore the relative performance of four dynamic lot-sizing techniques with regard to ROI, namely the Wagner-Whitin, Incremental Part Period, Silver-Meal, and Groff techniques. Computer graphics are employed to analyze the relative ROI effectiveness.
