社交电商中的社交-消费转换机制

社交情境和消费情境之间可以相互转换是社交电商的重要特征, 然而这种相互转换在现有社交电商采纳行为研究中却没有得到应有的重视。社交-消费转换概念的提出很好地弥补了上述研究不足。社交-消费转换是指用户从社交情境到消费情境的转换过程。基于边界理论, 从社群和用户两方面系统分析社交-消费转换的影响因素与促进机制, 有望构建体现社交电商专属特性的新理论, 帮助人们更加完整地理解社交电商采纳行为, 并为促进社交-消费转换提供切实可行的实践建议。研究内容具体包括以下4个方面：(1)社交电商中社交-消费转换的内涵与外延; (2)社群边界整合供给对整合型社交边界与社交-消费转换的影响; (3)用户边界分割偏好对整合型社交边界与社交-消费转换的影响; (4)社群边界定制氛围对整合型社交边界与社交-消费转换关系的调节作用。     

Parental negotiations of the moral terrain of risk in relation to young people with intellectual disabilities

This paper draws upon parental accounts from a study of the process of transition for a cohort of 28 young people with relatively severe intellectual disabilities who left special schools in 2004 and 2005 in two adjacent English localities. This paper examines how parents negotiate these boundaries and position themselves in relation to risk. A primary concern identified by parents during this transition period focuses on the risk of harm facing these vulnerable young people (whether through accidents or through sexual, emotional, physical or financial abuse) as they move into the adult world. These concerns are juxtaposed with discourses that increasingly promote the possibilities for people with intellectual disabilities to express and follow their own wishes and aspirations. For example, the policy agenda in England and Wales actively endorses the start of adult life as a time of opportunity for young people and promotes the values of independence and choice. In accounting for the management of risk in the young people's lives, we conclude that parents navigate complex boundaries between being seen to be over‐protective and ‘letting go’; between trusting others to act in the young adults' best interests and allowing these young people the autonomy to negotiate risk.

Morning Passages from Home to Work Among Managers in Israel: Intergender Differences

This paper presents a study on morning passages from home to work. The sample consisted of 226 Israeli parents working in managerial positions (136 men and 90 women). Eighty percent of the participants were Israeli-born, and the rest immigrated to Israel at a young age. In the study, I examined gender differences in emphasis on domestic and work activities at 3 main transitional stages in the morning: home transitions (30 min before leaving for work), on the way to work, and at work (the first 30 min after arrival at work). The findings indicate that in the home-transition women focused more on domestic tasks than on work tasks, whereas men showed the opposite tendency. On the way to work, women tended to intensify their involvement in work activities, but remained strongly concerned with domestic activities. Men, however, focused primarily on work tasks during this transition. In the work transition, both men and women were more concerned with work tasks than domestic tasks. Therefore, even though men and women focused on different tasks in the initial transition, by the time they arrived at the workplace, they were immersed to the same extent in work activities. Furthermore, the participants' age, children's ages, and years of marriage correlated negatively with emphasis on domestic tasks during the home transition regardless of gender.     

Age-Related Differences in the Transition from Adolescence to Adulthood and Links with Family Relationships

This study examined differences on major aspects of attaining adult status in the transition from adolescence into young adulthood. The attainment of developmental tasks and the quality of parent–child relationships were compared across adolescence and young adulthood. In addition, the extent to which relationships with parents are related to the attainment of young adulthood developmental tasks was also investigated. The study was conducted on 169 Israeli adolescents, early young adults, and late young adults. Results showed that developmental tasks are attained at different stages, and that the consolidation of adult status is achieved closer to the end of the third decade of life. Relationships with parents were found to be more positive following the transition from adolescence to early young adulthood. Adaptation of young adults was explained by the quality of relationships with parents and especially with fathers.     

Transition from School to Adult Life: Empowering Youth Through Community Ownership and Accountability

The evolution of transition services for youth with disabilities illustrates the transformation that has occurred from a systems-driven to a youth-centered support approach. This article documents how this shift has occurred. We review research that has influenced the direction of national policies and practices. A chronology of the policies that best represent the seminal foundation for current transition best practices for youth with emotional disturbance (ED) is presented. The field of special education led the way toward articulating the new vision for providing transition support by defining services as the coordination of multiple systems to address life domains (e.g., post-secondary education, employment, independent living, and community adjustment). Promising practices, within the context of the conversion to an ecological model of support that contributes to youth self-determination, include utilization of a youth-centered, strengths-based approach to transition planning, beginning in the middle school years. There remain significant barriers to adoption of the practices that may best support the successful transition of youth. These include lack of coordinated efforts across systems, socioeconomic, and community factors. Committed actions by government, the business sector, and private citizens are essential to address these challenges.     

The nanoeconomics of concurrent choice behavior

We introduce to behavior analysis a way of analyzing choice behavior that exploits recent developments in nanoeconomics, financial economics, and econometrics. A response return, modeled on an economic return, is the log differenced count of responses allocated to each of two alternatives during a short time window, compared with that in the immediately preceding window. The response return is a new dependent variable which offers a novel and useful way of looking at operant behavior, especially at the molecular level of analysis. The response–return series is a near‐instantaneous measure of an organism's dynamic preferences for each of two alternatives. Analyzing such a series requires time‐analytic techniques, including Auto‐Regressive Conditional Heteroskedastic (ARCH) models. We illustrate these techniques by analyzing choices between combinations of arithmetic and exponential variable‐interval schedules with pigeon subjects. All response–return series were well‐fitted by one of three ARCH‐family models. The fitted models were differentially sensitive to transition versus steady‐state data samples. The particular insights that the ARCH analyses offer are improved understanding of the effects of the instantaneous effects of reinforcers and their absence, of how the distribution of reinforcers in time affects choice, and of the differences between choice in transition and at steady state.     

Romantic attachment,dyadic coping,and parental adjustment across the transition to parenthood

This study explored the mediating role of common dyadic coping (common DC) on the longitudinal associations between attachment‐related anxiety and avoidance and parental adjustment to the first year postpartum. A total of 92 Portuguese couples completed self‐report questionnaires of romantic attachment, common DC, parenting stress, and parental confidence. Results showed that more avoidant parents (at mid‐pregnancy) engaged less in common DC (at 6 weeks postpartum), which consequently increased their partner's parenting stress (only in mothers) and decreased their partner's parental confidence (in both parents) at 6–9 months postpartum. Anxious attachment did not predict parents' adjustment directly or indirectly. Interventions aimed at preventing adjustment difficulties to early parenthood in more avoidant parents should focus on enhancing their common DC strategies soon after childbirth.     

The Next American Revolution？ Reflections on Gar Alperovitz,What Then Must We Do？

Marx is concerned with theory that not only interprets but also changes the world. A central issue is thus the transition from capitalism to communism, a topic rarely considered by critics of capitalism today. An important exception is Gar Alperovitz, who, although eschewing the word ＂communism,＂ argues that we need ＂a new system＂ and sketches a transition strategy for moving ＂beyond capitalism.＂ This paper elaborates and evaluates this strategy.     

Chest reconstructive surgeries in transmasculine youth: Experience from one pediatric center

Background: For many trans males, having chest reconstruction is a very important part of the transitioning process. Guidelines from WPATH and the Endocrine Society suggest 16 to 18 years old as an acceptable age for this surgical intervention. In clinical practice, the decision depends on factors such as a person's desires, insurance coverage, and availability of local surgical experts. We present data about chest reconstructive surgeries in transgender youth from a Pediatric Gender Management (GeM) clinic.

Methods: For this retrospective, observational study, data were collected from GeM clinic patients seen from 10/1/2011 to 1/31/2017. All subjects consented or assented to being included in an IRB-approved clinical database.

Results: Of 210 patients from our clinic, 167 consented to being added to an institutional review board–approved database and followed prospectively. The average age at the initial visit was 15.2 years (range, 4.7–20.9). Among consenting subjects, 55 were trans females, 108 were trans males, and four identified as nonbinary. Fourteen subjects had chest reconstruction with the mean age being 17.2 years (range, 13.4–19.7); three subjects were under age 16. For five subjects, including the youngest one, insurance paid for the procedure. All participants but one were receiving testosterone treatment. Per the surgeons' preferences, testosterone was usually not temporarily stopped prior to the procedure. Six subjects had the procedure done locally; others sought surgical care out of the town, state, or country. All subjects were very satisfied with the aesthetics of the surgical outcome. The self-reported complication rate was low. Many more GeM clinic patients wish to have breast/chest surgery but lack of insurance coverage makes the surgery cost prohibitive.

Conclusion: For many trans males, chest reconstructive surgery is an integral part of the transition process. Patients' age at the time of surgical procedure varies greatly; some have chest surgery before age 16. In the United States, chest reconstruction surgery is usually not covered by insurance. Therefore, many patients seeking surgical care are forced to pay out of pocket.     

The efficacy of a pilot pediatric cognitive remediation summer program to prepare for transition of care

This study assessed the efficacy of a time-sensitive cognitive remediation summer program (CRSP) that provided patients and their families with tools to help mitigate neurocognitive deficits and promote independence to foster precursor transition of medical care skills. A total of 38 participants (aged 9–15) were included in one of the CRSPs offered yearly from 2013 to 2016. A longitudinal design was employed and at each evaluation time point, one week before start of the CRSP (pre-testing) and within three weeks after the end of the program (post-testing)), participants were administered measures of executive functioning in addition to parent ratings of behavior, executive functioning, and adaptive skills (Year 1–Year 4). In Year 4, additional measures were collected, including parenting style and parent engagement and involvement in the program. Results from Year 1 to Year 4 (n = 35) demonstrated that participants in the CRSP showed significant improvement on neuropsychological testing in sustained and selective attention, planning, and cognitive flexibility. Robust changes in parent ratings of adaptive functioning from pre- to post-treatment were also found. Specific to Year 4 (n = 13), results revealed that participants showed improvement in levels of independence with at least one of the individualized goals focused on during the program. This study provided a systematic method to gauge the levels of instruction necessary to reach goals, a crucial tool in skill-teaching. Overall, our study provides evidence for the efficacy of the CRSP and validates a feasible intervention that can be integrated into standard of care for pediatric medical populations.
