Gendered images of international research collaboration

Joan Acker's theory on gendered organizations offers important tools for understanding subtler forms of inequalities and gendered practices in the workplace. According to Acker, invisible mechanisms in organizations such as the symbolic and material/structural aspects of organizations reproduce gendered inequalities. My application of Acker's theory demonstrates how imagery itself assigns value to collaborative practices in gender stereotypical ways. In an institutional context that devalues international research collaboration among faculty, gendered images of exploiter, patronizing helper, partner, or friend ultimately serve to construct glass fences ‐ obstacles to international collaborative engagement ‐ particularly for women. The reflection and potential recreation of gendered inequalities among academics simultaneously reconstructs inequalities between the U.S. and abroad, as institutional reward structures attach gendered symbolic and material values that (re)shape (international) collaborations themselves. Together, these processes construct the gendered organization of global science and academia.     

工程软件的小世界效应探究

工程信息具有形式复杂和内容分散的特点，其结构的关联性和数据的兼容性直接影响着数字化工程信息资源的有效管理和充分利用。特别是在工程信息的长期安全保存和可靠调用过程中，存在着信息和其使用系统之间的兼容问题和对信息定期检查、移存、转化的时间和效率问题。目前国内外对这两类问题还没有可行的解决方法和技术。根据“六度分离”现象和小世界网络模型，对工程软件的输入输出格式之间的转换关系进行实验分析，验证了其小世界效应，进一步通过Protégé 构建的本体查询格式转换的路径，为解决大量级和分散性工程信息的移存提供了可靠的科学依据。     

Volunteerism and Older Adults

Abstract

This study was designed to examine differences in care-giver and care recipient characteristics, caregiving and work demands and resources, and role strain among Black, Hispanic, Asian, and White employed family caregivers. Significant differences were found with respect to caregiver and care recipient characteristics, types of assistance provided, and workplace support. Minority caregivers were economically disadvantaged and provided higher levels of care. Whites reported higher levels of role strain than Black and Hispanic caregivers, after controlling for caregiver and care recipient characteristics, demands, and resources. The findings indicate that care giving policies and programs must be broadened to incorporate the strengths and needs of ethnically diverse caregivers. Family practitioners need to be able to assess the applicability and differential impact of particular interventions, policies, and benefits, and to design relevant programs for ethnically diverse care-givers and their families.     

论胡塞尔在《内时间意识现象学讲座》中的内时间意识结构理论

胡塞尔现象学是一门意识哲学,而内时间意识是诸意识形式中最基础的一种。在《内时间意识现象学》中,胡塞尔通过细致的分析,完成了对内时间意识之基本结构——由滞留——原印象——前摄共同构成的现在域——的描述,并且由此回答了奥古斯丁与布轮塔诺留下的时间难题。     

建设性后现代主义视域下的跨学科研究

从建设性后现代主义立场出发，认真分析现代社会中学科独立界限森严、STEM学科垄断一切、知识分类与标准绝对化等现象的形成原因、局限性及因此而带来的危害性，认为没有一种学科可以垄断一切。为了寻求真正的智慧，为了知识理解本身，为了更好地解决人类与生态福祉等综合性实际问题，我们必须超越传统的学科独立观念，走向现代社会更迫切需要的交叉学科和跨学科思维。     

人力资源管理系统与研发人员留职意愿——工作家庭促进与工作家庭冲突的中介效应

面对激烈的市场竞争,研发人员日益成为企业可持续发展的支柱力量。在既有研究的基础上重构了基于研发人员的双元（dual-concern model）人力资源管理模型（维持导向与绩效导向人力资源管理子系统）,探索了绩效与维持导向人力资源管理子系统通过工作家庭促进与工作家庭冲突中介影响留职意愿的作用机制。     

Are Self‐Service Customers Satisfied or Stuck?

This paper investigates the impact of self‐service technology (SST) usage on customer satisfaction and retention. Specifically, we disentangle the distinct effects of satisfaction and switching costs as drivers of retention among self‐service customers. Our empirical analysis examines 26,924 multi‐channel customers of a nationwide retail bank. We track each customer's channel usage, overall satisfaction, and retention over a 1‐year period. We find that, relative to face‐to‐face service, customers who use self‐service channels for a greater proportion of their transactions are either no more satisfied, or less satisfied with the service they receive, depending on the channel. However, we also find that these same customers are predictably less likely to defect to a competitor if they are heavily reliant on self‐service channels characterized by high switching costs. Through a mediation model, we demonstrate that, when self‐service usage promotes retention, it does so in a way that is consistent with switching costs. As a robustness check, we examine the behavior of channel enthusiasts, who concentrate transactions among specific channels. Relative to more diversified customers, we find that self‐service enthusiasts in low switching cost channels defect with greater frequency, while self‐service enthusiasts in high switching cost channels are retained with greater frequency.     

论国际保理商与供应商前手卖方间的权利冲突

在国际保理业务中,保理商与保留了货物所有权的供应商前手卖方之间可能发生权利冲突,这种所有权保留可能会影响保理商应收账款债权的实现.一旦发生冲突,谁将享有优先权?若无条件地认定所有权保留条款可对抗第三方,将不利于保护正常的交易秩序以及善意第三人的利益,使保理商的权利处于一种不可预知的不稳定状态.反之,过分强调第三人的利益也将不恰当地消弱所有权保留的物权担保功能.当前,关于此项权利冲突的问题上尚存在许多争议,各国的立法与司法实践亦有不同.在冲突解决时,应当遵循物权优先于债权、所有权保留公示、善意诚信等原则,以平衡各方的利益.其具体解决路径包括所有权保留登记立法例下冲突的解决,以及不要求所有权保留登记立法例下冲突的解决.     

“It's wicked hard to fight covert racism”: The case of microaggressions in science research organizations

The intersection of race and gender discrimination has resulted in the pervasive under-representation of women of color (WOC) in science careers, with research identifying that microaggressions are a key contributory factor to the imbalance. This study aims to compare individual experiences of microassaults, microinsults, and microinvalidations with institutional responses, thereby outlining the disconnects between the perspectives of minoritized scientists and those in positions of power. This paper draws on a constructivist paradigm to compare the experiences of women of color scientists with organizational representatives through 31 interviews conducted in science research organizations in the United Kingdom. The results find that organizational understandings of microaggressions differ substantially from those of WOC scientists. Furthermore, organizational responses favor policy-based solutions that fail to address the slippery and deniable nature of microaggressions. The paper concludes that, contrary to the more prevalent popular diversity initiatives, a greater belief in the testimony of WOC scientists amplified by institutional responses that empower their identity as scientists would be more effective strategies to reduce the sense of shame and isolation caused by subtle forms of discrimination.     

Truncated location-scale non linear regression models

We present a class of truncated non linear regression models for location and scale where the truncated nature of the data is incorporated into the statistical model by assuming that the response variable follows a truncated distribution. The location parameter of the response variable is assumed to be modeled by a continuous non linear function of covariates and unknown parameters. In addition, the proposed model also allows for the scale parameter of the responses to be characterized by a continuous function of the covariates and unknown parameters. Three particular cases of the proposed models are presented by considering the response variable to follow a truncated normal, truncated skew normal, and truncated beta distribution. These truncated non linear regression models are constructed assuming fixed known truncation limits and model parameters are estimated by direct maximization of the log-likelihood using a non linear optimization algorithm. Standardized residuals and diagnostic metrics based on the cases deletion are considered to verify the adequacy of the model and to detect outliers and influential observations. Results based on simulated data are presented to assess the frequentist properties of estimates, and a real data set on soil-water retention from the Buriti Vermelho River Basin database is analyzed using the proposed methodology.
