Parental reactions to developmental disabilities in Chinese American families

Families of Chinese American children with mental retardation and developmental disabilities were interviewed regarding their attitudes and coping experiences. Chinese American parents, like other American parents, reacted to the crisis with intense feelings and needs. The parents revealed a lack of knowledge and understanding of the diagnosis. Chinese belief systems about health and illness were present in the parents' concepts of causation and treatment.Hunter College School of Social Work.     

“THE WAR FOR THE FARE”: HOW DRIVER COMPENSATION AFFECTS BUS SYSTEM PERFORMANCE

Prior to 2007, two systems of bus driver compensation coexisted in Santiago, Chile: one paid drivers per passenger transported, while the other paid a fixed wage. Per‐passenger drivers engaged in “The War for the Fare,” altering their driving patterns to compete for passengers. Examining these systems on similar routes in Santiago, we observed two key findings. Compared with the fixed‐wage system, the per‐passenger system leads to (1) 13% shorter passenger wait times, via reduced bunching of buses and (2) 67% more accidents per kilometer driven, via more aggressive driving. We discuss implications for the design of incentives in public transit. (JEL L92, M52, R41)     

Risk Detection and Self‐Protection Among Homeless Youth

Utilizing qualitative interviews with a large sample of 145 homeless youth seeking services at homeless youth service agencies from across three U.S. cities (Los Angeles, Denver, and Austin), this study sought to explore youths' perspectives on ways in which they detect risk and protect themselves on the streets. Results indicated that youth use a combination of internal cues (affective responses) and external cues (reading people) to detect danger, although many times danger was described as undetectable. Certain contexts, includes those that were unfamiliar, difficult to escape, or involved drugs were described as most dangerous. In response to these dangers, youth employed self‐protection strategies such as carrying weapons, banding together with trusted others, isolating, or seeking programing to leave the streets.     

Marital Satisfaction,Family Emotional Expressiveness,Home Learning Environments,and Children's Emergent Literacy

The current study investigates associations among marital satisfaction, family emotional expressiveness, the home learning environment, and preschool‐aged children's emergent literacy skills among 385 Midwestern mothers and their children. Path analyses examined how marital satisfaction related to emotional expressiveness in the home and whether this path was associated with the home learning environment and children's literacy skills. Higher maternal satisfaction was associated with higher levels of positive and lower levels of negative family emotional expressiveness. Additionally, family emotional environments characterized by mothers with higher positive expression were related to better home learning environments, which in turn were associated with higher literacy skills in children. Study findings underscore the importance of marital and family processes when considering young children's academic development.     

Do the Kids Think They're Okay? Adolescents' Views on the Impact of Marriage and Divorce

A sample (N?=?365) of middle school and high school students from both divorced and intact families were surveyed with regard to their opinions about the impact of their parents' relationships (divorced or married) on a variety of areas of their lives. Adolescents from separated or divorced (S/D) families tended to rate their parents' relationships and impact on them more negatively than adolescents from living together or married (L/M) families. However, both groups consistently rated their parents in the same direction on a variety of topics. Gender was not a factor in the responses of either group. However, age (middle school vs. high school) was related to significant differences in adolescents' views about parents.     

Can Carbon Nanomaterials Improve CZTS Photovoltaic Devices? Evaluation of Performance and Impacts Using Integrated Life‐Cycle Assessment and Decision Analysis

In emergent photovoltaics, nanoscale materials hold promise for optimizing device characteristics; however, the related impacts remain uncertain, resulting in challenges to decisions on strategic investment in technology innovation. We integrate multi‐criteria decision analysis (MCDA) and life‐cycle assessment (LCA) results (LCA‐MCDA) as a method of incorporating values of a hypothetical federal acquisition manager into the assessment of risks and benefits of emerging photovoltaic materials. Specifically, we compare adoption of copper zinc tin sulfide (CZTS) devices with molybdenum back contacts to alternative devices employing graphite or graphene instead of molybdenum. LCA impact results are interpreted alongside benefits of substitution including cost reductions and performance improvements through application of multi‐attribute utility theory. To assess the role of uncertainty we apply Monte Carlo simulation and sensitivity analysis. We find that graphene or graphite back contacts outperform molybdenum under most scenarios and assumptions. The use of decision analysis clarifies potential advantages of adopting graphite as a back contact while emphasizing the importance of mitigating conventional impacts of graphene production processes if graphene is used in emerging CZTS devices. Our research further demonstrates that a combination of LCA and MCDA increases the usability of LCA in assessing product sustainability. In particular, this approach identifies the most influential assumptions and data gaps in the analysis and the areas in which either engineering controls or further data collection may be necessary.     

Defender–Attacker Decision Tree Analysis to Combat Terrorism

We propose a methodology, called defender–attacker decision tree analysis, to evaluate defensive actions against terrorist attacks in a dynamic and hostile environment. Like most game‐theoretic formulations of this problem, we assume that the defenders act rationally by maximizing their expected utility or minimizing their expected costs. However, we do not assume that attackers maximize their expected utilities. Instead, we encode the defender's limited knowledge about the attacker's motivations and capabilities as a conditional probability distribution over the attacker's decisions. We apply this methodology to the problem of defending against possible terrorist attacks on commercial airplanes, using one of three weapons: infrared‐guided MANPADS (man‐portable air defense systems), laser‐guided MANPADS, or visually targeted RPGs (rocket propelled grenades). We also evaluate three countermeasures against these weapons: DIRCMs (directional infrared countermeasures), perimeter control around the airport, and hardening airplanes. The model includes deterrence effects, the effectiveness of the countermeasures, and the substitution of weapons and targets once a specific countermeasure is selected. It also includes a second stage of defensive decisions after an attack occurs. Key findings are: (1) due to the high cost of the countermeasures, not implementing countermeasures is the preferred defensive alternative for a large range of parameters; (2) if the probability of an attack and the associated consequences are large, a combination of DIRCMs and ground perimeter control are preferred over any single countermeasure.     

Model-based clustering,classification, and discriminant analysis of data with mixed type

We propose a mixture of latent variables model for the model-based clustering, classification, and discriminant analysis of data comprising variables with mixed type. This approach is a generalization of latent variable analysis, and model fitting is carried out within the expectation-maximization framework. Our approach is outlined and a simulation study conducted to illustrate the effect of sample size and noise on the standard errors and the recovery probabilities for the number of groups. Our modelling methodology is then applied to two real data sets and their clustering and classification performance is discussed. We conclude with discussion and suggestions for future work.     

Beyond the Self: External Influences in the Career Development Process

The purpose of this article is to explore the wide spectrum of external influences that affect career decision making across the life span and, in particular, how these factors may directly or indirectly alter one's career trajectory and the extent of one's work volition. Career development practitioners are encouraged to respect externally oriented frameworks, explore the social influence of career choice alternatives faced by clients, encourage clients to voice their emotional responses to external constraints, and use career decision‐making strategies that seek an optimal balance of internal and external influences.     

印度东北与中国西南的民族志诗歌

印度东北与中国西南在地域上山水相连,相互之间的文化交流是非常密切的。这个区域里居住着众多的民族或族群,他们的文化相似性和可比性是很明显的。从跨国的视角来探寻文化互动或文化个性,这是一个理想的地域。这些不同民族或族群身份的诗人写作的民族志诗歌是探寻各自文化共性和个性的较好途径：虽然诗歌创作过程中采用不同的语言,印度东北的土著诗人通常用英语写作,中国西南少数民族诗人经常用汉语写作,但是这些诗人都受到了近代西方现代主义诗歌潮流的影响。同时,这些诗人的诗歌也受到了当下全球化的影响,比如本民族传统文化与文化教育现代化、全球生态环境日益恶化等等冲突的影响。因为受到了相似的影响,这个区域内的民族志诗歌的风格和肌理是可以比较的;诗歌的主题和内容也是可以展开对比研究的。
