College-bound friends and college application choices: Heterogeneous effects for Latino and White students

Friends are among the most influential social forces affecting adolescent behavior, yet little work has focused on the influence of friends on the decision to apply to college. Using data from the senior cohort of the Texas Higher Education Opportunity Project, we employed propensity score matching with sensitivity analyses to investigate links between having college-oriented friends and applying to college. We found that college-oriented friends increased the likelihood of applying to any college and to 4-year colleges, both for White and Latino students. However, Latino students benefited less from college-oriented friends compared to White students. Our findings suggest that college-choice models should more directly account for the influence of friends in applying to college, taking account of racial and ethnic differences, and future research should explore why Latino students benefit less.     

Level of choice in older women’s decisions to retire or continue working and associated well-being

Retirement is a complex life transition. Women’s retirement, like their work lives, may be further complicated, for example, by family or financial obligations; they may feel forced to retire or to continue working or feel they have the choice to do so. This study examines the role of voluntary versus involuntary retirement or continued work participation among retirement-age women; specifically, the relationships between choice, work status, and well-being. Compared to women forced to retire, women who chose retirement or continuing to work had higher levels of life satisfaction. Findings highlight the importance of examining retirement within the life course context.     

High value manufacturing (HVM) in the UK: case studies and focus group insights

This paper studies the internal mechanisms that allow organisations to become high value manufacturing (HVM). Using a qualitative methodology, three UK manufacturing companies formed in-depth case studies with semi-structured interviews, observations and historical data. The HVM value matrix of Martinez and co-workers is used to categorise each organisation’s value proposition. Wider benchmarking of the three organisations was carried out against a focus group with an additional seven manufacturing organisations. Thus, data from 10 manufacturing organisations are included in this research. The cases follow the ‘customer intimacy’ HVM discipline. The business processes supporting these value propositions were identified. Interestingly, each organisation’s desired value proposition differs from their current one. ‘Technological integrators’ predominantly rely on new product development (NPD) and Strategy processes, whereas ‘Socialisors’ rely predominantly on Strategy and Customer Relationship processes. Companies can use the findings to better understand their current HVM value proposition and, where necessary, plan their transition to a future desired HVM value proposition.     

College-conocimiento: toward an interdisciplinary college choice framework for Latinx students

This paper builds upon Perna’s college choice model by integrating Anzaldúa’s theory of conocimiento to propose an interdisciplinary college choice framework for Latinx students. Using previous literature, this paper proposes college-conocimiento as a framework that contextualizes Latinx student college choices within the inequitable distribution of institutional resources in the K-12 system. In particular, the framework centers on the notion that a lack of adequate college guidance can influence a cyclical Latinx college choice process. College-conocimiento is defined as a serpentine process where Latinx students reflect on the college information that they receive, in relation to their intersectional identities when preparing for college. The pathway of college-conocimiento entails seven cyclical spaces and aims for students to develop a reflective college consciousness, exemplified through self-advocacy and supporting peers with the college choice process. This paper challenges college choice as a sequential process by noting that students can repeat stages as needed.     

基于ART及多风险规避的交通网络均衡模型

随着对交通系统不确定性认识的深入,以绝对理性为基础的“期望效用理论”在风险环境下的路径选择分析中显示出局限性,而“预期后悔理论”则为之提供了新的分析思路.将预期后悔理论应用到风险环境下的路径选择分析中,将出行者一致风险规避的假设扩展到多风险规避,建立了基于后悔理论及多风险规避出行特征的交通网络随机用户均衡变分不等式模型,并给出了求解算法.通过算例分析发现,后悔心理对出行者的路径选择并不总是显著的.在非风险环境及极端风险环境中,后悔心理对出行者的路径选择影响是微弱的,但是当环境处于极端风险与非风险之间时,后悔心理对出行者路径选择有着较为显著的影响.     

The time‐dependent “cure‐death” model investigating two equally important endpoints simultaneously in trials treating high‐risk patients with resistant pathogens

A variety of primary endpoints are used in clinical trials treating patients with severe infectious diseases, and existing guidelines do not provide a consistent recommendation. We propose to study simultaneously two primary endpoints, cure and death, in a comprehensive multistate cure‐death model as starting point for a treatment comparison. This technique enables us to study the temporal dynamic of the patient‐relevant probability to be cured and alive. We describe and compare traditional and innovative methods suitable for a treatment comparison based on this model. Traditional analyses using risk differences focus on one prespecified timepoint only. A restricted logrank‐based test of treatment effect is sensitive to ordered categories of responses and integrates information on duration of response. The pseudo‐value regression provides a direct regression model for examination of treatment effect via difference in transition probabilities. Applied to a topical real data example and simulation scenarios, we demonstrate advantages and limitations and provide an insight into how these methods can handle different kinds of treatment imbalances. The cure‐death model provides a suitable framework to gain a better understanding of how a new treatment influences the time‐dynamic cure and death process. This might help the future planning of randomised clinical trials, sample size calculations, and data analyses.     

Housing of Seniors in the Czech Republic: Challenges for Social Services

The article focuses on the housing market, the behavior and motivations of senior households to move or to stay in place. Knowing if and why seniors decide to move at retirement is a critical factor for the establishment of social service policies in terms of their structure, location, and provision.

This study uses secondary data based on information about Czech households collected by the Czech Statistical Office (CSO). The data are annually collected via sample surveys of the income and living conditions of households (EU-SILC). The sample covers more than eight thousands of households. Analyzed data cover the period 2007–2012 when the abolishment of rent regulation in the Czech Republic took place. It is hypothesized that an impact like this might increase the willingness to move and reveal the factors which underlie the decisions of particular households.

The results indicated that most Czech households that decided to move during the study period were driven by the increased financial burden of housing. Other factors, including the availability of social services and public utilities within the current location, played only minor roles. It seems that Czech senior households act in a very pragmatic and rational manner when deciding whether to stay in place or move, with the majority of households preferring not to move. Social policies should, therefore, concentrate on providing services for the current locations rather than on the construction of new social housing.     

论图书馆的信息推送服务

信息推送服务是一种个性化的主动信息服务,图书馆在服务过程中必须贯彻以人为本、主动服务、一站式服务、个性化服务理念;网络环境下,基于RSS的信息推送模式比较好的解决信息推送的技术手段,图书馆根据学校的特性选择信息,建立用户需求库、信息资源库,定制用户界面并协同数据库完成信息推送。因此,以用户为中心的信息推送技术必将成为未来信息获取技术的一个重要发展方向。     

基于Logit模型的区域集镇系统需求分析及规模确定研究

集镇迁建并非简单的将集镇按照原规模从一个地方搬到另一个地方,集镇迁建规模的大小．应该根据迁入区的实际需求（需求规模）来确定,需求的大小主要取决于村民对集镇的选择行为,即越多的人选择到某个集镇进行活动,该集镇的需求规模越大,反之越小。影响集镇需求的因素很多,包括交通时间、交通费用、集镇服务种类、服务质量等,本文将其概括为广义费用和集镇效用（服务能力）,建立反映村民选择行为的Logit模型分析集镇需求情况,并将其应用于区域集镇系统布局优化中,以我国西部某地为例进行实证分析,反映搬迁前后一定区域内各榘镇需求规模的变化,同时计算出新集镇的需求规模,为集镇迁建规模的确定及其布局优化提供科学的参考。     

高职院校学生的生育道德观现状与实证研究

研究分别以分层丛集式问卷与子女价值量表对24岁以下的高职学生进行生育道德观的实证分析,旨在探讨生育道德观与未来希望生育子女数及生育挟择的整体关系。结果发现：高职学生以“权力成就”、“亲密情感”、“家庭愉悦”为最主要的认同层面;生育道德观因性剐、交友情况、父母教育程度等成长经验的不同而有所差异;生育道德观中“生育价值”、“生育代价”、“生育挟择”因素对未来希望生育子女数有一定程度的预测力。
