‘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.
