In this study, we investigate linear regression having both heteroskedasticity and collinearity problems. We discuss the properties related to the perturbation method. Important observations are summarized as theorems. We then prove the main result that states the heteroskedasticity-robust variances can be improved and that the resulting bias is minimized by using the matrix perturbation method. We analyze a practical example for validation of the method. 相似文献

This qualitative study focuses on the different ways time is experienced by children in families who face time challenges because of a family member's job that required work travel. Data are from a family‐level study that includes interviews of all family members older than age 7. Using grounded theory methodology, this study illustrates the ways in which job demands and family processes interact. The analysis centers on 75 children's perspectives from 43 families. Holding together assessments of having enough time while wanting more time with their parents, children express emotion, generally unrecognized by parents, around the topic of family time. Children's experience of time with parents is rushed or calm, depending on the activities done in time and the gender of the parent with whom they spend time. Findings are interpreted through a feminist social constructionist lens. 相似文献

In this interpretive case study the researchers examined the beliefs of 13 self-identifying race-conscious secondary social studies teachers from diverse racial or ethnic, gender, and school-context backgrounds. The researchers found that the teachers' beliefs and views of practice were generally aligned with the main assertions of critical race theory. The teachers described their personal and professional experiences as a major influence on their race-conscious beliefs and views of practice. Moreover, teachers in diverse contexts described having to learn how to navigate the different racial experiences of the students in their classrooms, while teachers in racially segregated contexts (predominately White, Black, or Latino) emphasized the importance of teaching their students about others. Finally, despite the teachers' regular integration of race-related issues into their required and elective courses, they expressed a desire to have more opportunities to teach about race. 相似文献

Public works programmes (PWPs) are popular social protection instruments in the context of chronic poverty but very little has been published in the way of implementation and outcomes of these programmes. This paper presents a formative process and outcome evaluation of the recovery PWP in Blantyre City, Malawi. The evaluation used longitudinal household survey data of PWP beneficiaries, programme records and interview responses from programme staff and community leaders. Largely, the process evaluation findings showed an agreement between actual and planned activities. The outcome evaluation found indications that the PWP community assets offered some potential benefits to the communities, and that PWP wages allowed the beneficiaries to purchase some food. This however, did not translate into more meals per day, nor did the earnings prevent the decline in household assets as expected. Given a plausible PWP theory and high implementation fidelity, the PWP wage rate or number of days was either just enough to smooth participant income, or insufficient altogether, to enable achievement of more distal outcomes. 相似文献

In this experiment, I examine the extent to which competitive social preferences can explain over-bidding in rent-seeking contests. The Human treatment is a standard two-player contest. In the Robot treatment, a single player bids against a computerized player, eliminating potential social preference motives. The results show no difference in bids between treatments at the aggregate level. Further analysis shows evidence of heterogeneous treatment effects between impulsive and reflective subjects. Moreover, impulsive subjects are more likely than reflective subjects to deviate qualitatively from the shape of the theoretical best response function. 相似文献

This paper presents findings from research about how practice teachers in social care education in Ireland view their role, in particular what elements they prioritise and what they see as relatively unimportant. The aim of the research was exploratory, seeking to discover commonalities and differences in how practice teachers saw their role in the supervision of social care students. Q methodology was used to compare the participants’ viewpoints. Twenty practice teachers, from varying practice backgrounds and levels of experience, sorted statements outlining aspects of the practice teacher’s role, during individual interviews. Analysis indicates participants had two ways of conceptualising the role. One focuses within the agency, prioritising students’ awareness of the clients using the social care service and policies as guiding practice. The second encapsulates a broader view of learning beyond the agency, focusing on the practice teacher assisting the student to integrate theory with practice and using reflection as a learning tool. Conclusions are drawn in relation to social care education. 相似文献

Psychosocial benefits of activism include increased empowerment, social connectedness, and resilience. Yet sexual minority women (SMW) and transgender individuals with multiple oppressed statuses and identities are especially prone to oppression-based experiences, even within minority activist communities. This study sought to develop an empirical model to explain the diverse meanings of social justice activism situated in SMW and transgender individuals’ social identities, values, and experiences of oppression and privilege. Using a grounded theory design, 20 SMW and transgender individuals participated in initial, follow-up, and feedback interviews. The most frequent demographic identities were queer or bisexual, White, middle-class women with advanced degrees. The results indicated that social justice activism was intensely relational, replete with multiple benefits, yet rife with experiences of oppression from within and outside of activist communities. The empirically derived model shows the complexity of SMW and transgender individuals’ experiences, meanings, and benefits of social justice activism. 相似文献

The contested definitions of “swinging” and “polyamory” reveal profound inconsistencies in the logics of sex, love, commitment, and coupledom. In this article, I use a number of non-monogamy blogs and online glossaries as examples of the way these two words are often deployed against each other in an effort to position the speaker in relation to mononormative practices of sex and love. Leaving aside questions of the accuracy of particular definitions, I map a range of definitions against two existing scholarly/activist tools for describing relationship styles, specifically Gayle Rubin’s “Charmed Circle” and Meg-John Barker’s sex/love continuums. This exercise is doubly fruitful: first, the tools reveal the political stakes of the definitional debates; second, the definitions demonstrate that the distinctions we commonly use to distinguish between types of relationships—including types of non-monogamous relationships—in fact rely on mononormative assumptions about sex, love, and friendship. If “mononormativity” is defined as the system of ideas, institutions, and practical orientations that provide the backdrop against which the idea of monogamy as coherent, common, natural, and right congeals, the sex/love skirmishes of “swinging” and “polyamory” remind us that its logics are both pervasive and deeply fractured. 相似文献
