Parents’ perspectives of social support and social cohesion in urban contexts of diversity

Although provisions for young children are increasingly considered as ideal places to foster an inclusive and socially just society by embracing issues of social support and social cohesion, there is no in-depth understanding of the role these provisions can play in enabling supportive and cohesive encounters in contexts of diversity. Even more striking is the absence of parents’ voices in this discussion. Based on an analysis of qualitative interviews with 18 parents who use childcare services in urban contexts of diversity, our findings show the relevance of ephemeral contacts with diverse people that could offer bridging opportunities in terms of social connectedness to familiarise within diversity while decoding the other in urban contexts of diversity. However, neither bonding nor bridging contacts appear as self-evident. Our research shows that the role of childcare services might be vital in creating light and temporal communities as the prerequisite for social cohesion to flourish, in both individual as well as collective dimensions.     

Key Determinants to using Telehealth Technology to Serve Medically Ill and Depressed Homebound Older Adults

Despite the increasing evidence for the effectiveness of telehealth technology in screening and treating chronic diseases, and comorbid depression among older adults, they have been slowly adopted by home health care (HHC) agencies. Therefore, this study aimed to identify factors that determine telehealth technology adoption. Twenty directors from the National Association for Homecare & Hospice member agencies completed a 45-min telephone interview. Questions were asked regarding their perceptions of telehealth, the key determinants of telehealth adoption and use, and recommendations they would give on telehealth adoption. The majority of the participants perceived telehealth as effective for managing symptoms and reducing cost. Meanwhile, some participants had a mixed feeling toward telehealth for depression care as they did not recognize their agency as equipped with the necessary resources and trained staff. Moreover, significant determinants of telehealth adoption included the agency-related characteristics, the patient-home environment, reimbursement and cost-related factors, and staff telehealth perception. Findings imply that there is a need for financial support both at the state and the federal levels to encourage telehealth adoption among HHC agencies. Future studies should consider exploring strategies used by successful programs to overcome barriers.     

‘Before they kill my spirit entirely’: insights into the lived experiences of American Indian Alaska Native faculty at research universities

American Indian and Alaska Natives (AIAN) comprise about 2% of the US population and 0.5% of the faculty in higher education. While scholars have documented the experiences of underrepresented minority (URM) faculty, the perspectives of AIAN faculty at elite universities are largely absent. Although AIAN faculty share many of the same barriers to success as URM colleagues, their unique status as Tribal peoples and their relationship to settler colonialism pose particular challenges and resistance strategies. Findings from a mixed methods study of 25 AIAN faculty at research universities, employing a decolonizing, survivance-oriented framework, examines their lived institutional experiences. The data yielded five themes regarding (1) institutional climate, (2) mentorship, (3) family–work balance, (4) cultural taxation and role stress, and (5) discrimination. The authors conclude that decolonization involves the repatriation of Indigenous epistemologies and Indigenous ‘place’ in the growth of science, research, and knowledge production, creating liberatory spaces within the academy.     

Reclaiming ourselves through Testimonio pedagogy: reflections on a curriculum design lab in teacher education

This article details one teacher preparation course centering Latin American Testimonio narratives of struggle/survival amid structural oppression for use in secondary curriculum. As our class of predominantly Latina/o students and two Latina instructors engaged Testimonio pedagogy, we fashioned a hopeful alternative to our own experiences of intergenerational oppression. While research indicates that the experiences and histories of pre-service Teachers of Color lend pedagogical strength and critical consciousness to teacher education, three Latina pre-service students highlight the ways in which Testimonio became more than a pedagogical approach. Testimonio’s collectivity, resistance, hope, and assertions of voice and dignity moved through them not as educators first but as (great-grand)daughters of oppressed though still-resilient People(s). Testimonio emboldened these Latina pre-service educators to recognize and validate their own inherited multiliteracies, (re)claim their connectedness to land, and articulate their visions for more equitable schooling. This work advances research into the essentiality of engaging race and ethnicity in K-12 and teacher education curriculum and pedagogy.     

SOME COMMENTS ON “A SYSTEMS PERSPECTIVE ON MATERIALS REQUIREMENTS PLANNING”*

We believe there are some serious deficiencies in the Morecroft article on MRP problems which appeared in a recent issue of this journal. The article, at the most, shows that MRP, inappropriately imposed on an existing production system, can result in undesirable system performance. This does not represent a new or startling conclusion. Four problem areas in the article are discussed, and suggested alternative approaches are offered.     

A ONE-PERIOD STOCHASTIC INVENTORY PROBLEM WITH A LUMP-SUM PENALTY COST

This paper presents an inventory problem related to the one-period stochastic inventory (or “newsboy”) problem. In this problem, the firm has to decide how much product to order to meet a random one-period demand. The version of the problem presented is novel in two respects. First, demand is explicitly permitted to be negative, and second, the penalty (or shortage) cost is assumed to be independent of the magnitude of the shortage. This situation is shown to change the form of the cost function and to complicate the determination of optimal policies. The form of the optimal policy is developed, and two example problems are presented in some detail.

尿液中氯胺酮的固液提取方法比较

研究了液-液提取法和固相提取法对尿液中氯胺酮提取的差异,并明确了两种提取方法的适用条件.结果表明,两种提取方法均能有效地将氯胺酮从尿液中提取,但液-液提取法操作简单,省时高效,适合于筛选检验;而固相提取法污染少,操作人员与试剂接触少,但操作时间相对较长,适用于氯胺酮的定量分析.
