Review of Native Americans in the School System: Family, Community, and Academic Achievement by Carol J. Ward

The title of this volume promises more than the content delivers. The heart of the book is information from Ward's 1992 University of Chicago doctoral dissertation, which focused on the social and cultural reasons leading to students dropping out of school. Her first two chapters provide a good review of research on dropouts and Indian education; the following six focus on the results of her 1987-1989 study of 698 Northern Cheyenne, Crow, and white high school students attending the Colstrip Public, St. Labre Catholic, and Busby Tribal Schools in Montana. Fifty-two percent of the students in this study were Indian, with a dropout rate of 45% .

Educational Investment, Family Context, and Children’s Math and Reading Growth from Kindergarten through the Third Grade

Drawing on longitudinal data from the Early Childhood Longitudinal Study, Kindergarten Class of 1998–1999, this study used IRT modeling to operationalize a measure of parental educational investments based on Lareau’s notion of concerted cultivation. It used multilevel piecewise growth models regressing children’s math and reading achievement from entry into kindergarten through the third grade on concerted cultivation and family context variables. The results indicate that educational investments are an important mediator of socioeconomic and racial/ethnic disparities, completely explaining the black-white reading gap at kindergarten entry and consistently explaining 20 percent to 60 percent and 30 percent to 50 percent of the black-white and Hispanic-white disparities in the growth parameters, respectively, and approximately 20 percent of the socioeconomic gradients. Notably, concerted cultivation played a more significant role in explaining racial/ethnic gaps in achievement than expected from Lareau’s discussion, which suggests that after socioeconomic background is controlled, concerted cultivation should not be implicated in racial/ethnic disparities in learning.

Work and Family: a complex interplay. An Italian application of the DISC Model on health care workers

The present thesis investigates the issue of work-family conflict and facilitation in a sanitarian contest, using the DISC Model (De Jonge and Dormann, 2003, 2006). The general aim has been declined in two empirical studies reported in this dissertation chapters. Chapter 1 reporting the psychometric properties of the Demand-Induced Strain Compensation Questionnaire. Although the empirical evidence on the DISC Model has received a fair amount of attention in literature both for the theoretical principles and for the instrument developed to display them (DISQ; De Jonge, Dormann, Van Vegchel, Von Nordheim, Dollard, Cotton and Van den Tooren, 2007) there are no studies based solely on psychometric investigation of the instrument. In addition, no previous studies have ever used the DISC as a model or measurement instrument in an Italian context. Thus the first chapter of the present dissertation was based on psychometric investigation of the DISQ. Chapter 2 reporting a longitudinal study contribution. The purpose was to examine, using the DISC model, the relationship between emotional job characteristics, work-family interface and emotional exhaustion among a health care population. We started testing the Triple Match Principle of the DISC Model using solely the emotional dimension of the strain-stress process (i.e. emotional demands, emotional resources and emotional exhaustion). Then we investigated the mediator role played by w-f conflict and w-f facilitation in relation to emotional job characteristics and emotional exhaustion. Finally we compared the mediator model across workers involved in chronic illness home demands and workers who are not involved. Finally, a general conclusion, integrated and discussed the main findings of the studies reported in this dissertation.

Inhibition of FcepsilonRI-dependent mediator release and calcium flux from human mast cells by sialic acid-binding immunoglobulin-like lectin 8 engagement

BACKGROUND: Sialic acid-binding immunoglobulin-like lectins (Siglecs) are a family of glycan-binding inhibitory receptors, and among them, Siglec-8 is selectively expressed on human eosinophils, basophils, and mast cells. On eosinophils, Siglec-8 engagement induces apoptosis, but its function on mast cells is unknown. OBJECTIVE: We sought to study the effect of Siglec-8 engagement on human mast cell survival and mediator release responses. METHODS: Human mast cells were generated from CD34+ precursors. Apoptosis was studied by using flow cytometry. Mast cell mediator release or human lung airway smooth muscle contraction was initiated by FcepsilonRI cross-linking with or without preincubation with Siglec-8 or control antibodies, and release of mediators was analyzed along with Ca++ flux. RBL-2H3 cells transfected with normal and mutated forms of Siglec-8 were used to study how Siglec-8 engagement alters mediator release. RESULTS: Siglec-8 engagement failed to induce human mast cell apoptosis. However, preincubation with Siglec-8 mAbs significantly (P < .05) inhibited FcepsilonRI-dependent histamine and prostaglandin D(2) release, Ca++ flux, and anti-IgE-evoked contractions of human bronchial rings. In contrast, release of IL-8 was not inhibited. Siglec-8 ligation was also shown to inhibit beta-hexosaminidase release and Ca++ flux triggered through FcepsilonRI in RBL-2H3 cells transfected with full-length human Siglec-8 but not in cells transfected with Siglec-8 containing a tyrosine to phenylalanine point mutation in the membrane-proximal immunoreceptor tyrosine-based inhibitory motif domain. CONCLUSION: These data represent the first reported inhibitory effects of Siglec engagement on human mast cells.

Human basophils and eosinophils are the direct target leukocytes of the novel IL-1 family member IL-33

In mice, interleukin-18 (IL-18) regulates Th1- or Th2-type immune responses depending on the cytokine environment and effector cells involved, and the ST2-ligand, IL-33, primarily promotes an allergic phenotype. Human basophils, major players in allergic inflammation, constitutively express IL-18 receptors, while ST2 surface expression is inducible by IL-3. Unexpectedly, freshly isolated basophils are strongly activated by IL-33, but, in contrast to mouse basophils, do not respond to IL-18. IL-33 promotes IL-4, IL-13 and IL-8 secretion in synergy with IL-3 and/or FcepsilonRI-activation, and enhances FcepsilonRI-induced mediator release. These effects are similar to that of IL-3, but the signaling pathways engaged are distinct because IL-33 strongly activates NF-kappaB and shows a preference for p38 MAP-kinase, while IL-3 acts through Jak/Stat and preferentially activates ERK. Eosinophils are the only other leukocyte-type directly activated by IL-33, as evidenced by screening of p38-activation in peripheral blood cells. Only upon CD3/CD28-ligation, IL-33 weakly enhances Th2 cytokine expression by in vivo polarized Th2 cells. This study on primary human cells demonstrates that basophils and eosinophils are the only direct target leukocytes for IL-33, suggesting that IL-33 promotes allergic inflammation and Th2 polarization mainly by the selective activation of these specialized cells of the innate immune system.

Cross-cultural perspectives on adolescents’ religiosity and family orientation

This chapter explores cultural and individual religious roots of adolescents' family orientation on the basis of multilevel analyses with data from 17 cultural groups. Religion and the family are seen as intertwined social institutions. The family as a source of social support has been identified as an important mediator of the effects of religiosity on adolescent developmental outcomes. The results of the current study show that religiosity was related to different aspects of adolescents' family orientation (traditional family values. value of children, and family future orientation), and that the culture-level effects of religiosity on family orientation were stronger than the individual-level effects. At the cultural level, socioeconomic development added to the effect of religiosity, indicating that societal affluence combined with nonreligious secular orientations is linked to a lower family orientation, especially with regard to traditional family values. The authors suggest that individual religiosity may be of special importance for adolescents' family orientation in contexts where religiosity has lost some significance but religious traditions are still alive and can be (re-)connected to.

S100A4 is a molecular mediator of endometrial carcinoma invasion

The molecular mechanisms of endometrail cancer invasion are poorly understood. S100A4, a member of the S100 Ca2+-binding protein family, was identified by oligonucleotide microarray qRT-PCR, and IHC, to be highly overexpressed in invasive endometrial carcinomas compared to non-invasive tumors. HEC-1A endometrial cancer cells transfected with S100A4 siRNA had undetectable S100A4 protein, decreased migration and invasion. The mechanism of S100A4 upregulation in endometrial cancer remains unclear. Methylation of the S100A4 gene was detected in benign endometrial glands and grade 1 tumors with no S100A4 expression. In contrast, grade 3 endometrioid tumors with high S100A4 expression showed no methylation of the gene. 5-Aza-2'-deoxycytidine, an inhibitor of DNA methyltransferase, induced the expression of S100A4 in the less invasive EC cell line, KLE, in which the S100A4 gene is hypermethylated and minimally expressed. S100A4 was induced during TGF-β1-triggered cell scattering in HEC-1A cells, in which S100A4 was demethylated. Transfection of HEC-1A cells with S100A4 siRNA significantly reduced the effect of TGF-β1 on basal migration and invasion. Our preliminary data suggested that this upregulation was mediated by the transcription factor Snail. One Snail binding consensus site was found in the region where DNA methylation was closely correlated with S100A4 gene expression. Chromatin immunoprecipitation assay confirmed the binding of Snail to this consensus site in HEC-1A cells. In SPEC2 endometrial cancer cells, loss of Snail leads to repressed S100A4 gene expression. Similar to S100A4, Snail was overexpressed in aggressive endometrial tumors. Our study suggested that the S100A4 gene was demethylated and further upregulated by the TGF-β1 and Snail pathway in invasive endometrial cancer. S100A4 could potentially serve as a good molecular marker for invasiveness and a target for therapeutic intervention for advanced endometrial cancer. ^

Assembly of RecA-like recombinases: Distinct roles for mediator proteins in mitosis and meiosis

Members of the RecA family of recombinases from bacteriophage T4, Escherichia coli, yeast, and higher eukaryotes function in recombination as higher-order oligomers assembled on tracts of single-strand DNA (ssDNA). Biochemical studies have shown that assembly of recombinase involves accessory factors. These studies have identified a class of proteins, called recombination mediator proteins, that act by promoting assembly of recombinase on ssDNA tracts that are bound by ssDNA-binding protein (ssb). In the absence of mediators, ssb inhibits recombination reactions by competing with recombinase for DNA-binding sites. Here we briefly review mediated recombinase assembly and present results of new in vivo experiments. Immuno-double-staining experiments in Saccharomyces cerevisiae suggest that Rad51, the eukaryotic recombinase, can assemble at or near sites containing ssb (replication protein A, RPA) during the response to DNA damage, consistent with a need for mediator activity. Correspondingly, mediator gene mutants display defects in Rad51 assembly after DNA damage and during meiosis, although the requirements for assembly are distinct in the two cases. In meiosis, both Rad52 and Rad55/57 are required, whereas either Rad52 or Rad55/57 is sufficient to promote assembly of Rad51 in irradiated mitotic cells. Rad52 promotes normal amounts of Rad51 assembly in the absence of Rad55 at 30°C but not 20°C, accounting for the cold sensitivity of rad55 null mutants. Finally, we show that assembly of Rad51 is induced by radiation during S phase but not during G1, consistent with the role of Rad51 in repairing the spontaneous damage that occurs during DNA replication.

Affective Commitment and Job Satisfaction among Non-family Employees: Investigating the Roles of Justice Perceptions and Psychological Ownership

Due to numerous characteristics often attributed to family firms, they constitute a unique context for non-family employees’ justice perceptions. These are linked to non-family employees’ pro-organizational attitudes and behaviors, which are essential for family firms’ success. Even though scholarly interest in non-family employees’ justice perceptions has increased, more research is still needed, also because the mechanism connecting justice perceptions and favorable outcomes is not fully understood yet. We address this gap by explicitly investigating non-family employees’ justice perceptions and by introducing psychological ownership as a mediator in the relationships between justice perceptions (distributive and procedural) and common work attitudes (affective commitment and job satisfaction). Our analysis of a sample of 310 non-family employees from Germany and German-speaking Switzerland reveals that psychological ownership mediates the relationships between distributive justice and affective commitment as well as job satisfaction. This represents valuable contributions to family business research, organizational justice and psychological ownership literature, and to practice.

The Committed and the Happy: Exploring the Effects of Justice and Ownership Perceptions among Non-family Employees

A main challenge that family businesses face is fostering non-family employees' val-ue-creating attitudes, such as affective commitment and job satisfaction. While justice perceptions have been identified as being critical in the creation of these outcomes, the process how they actually evolve is less clear, especially in family firms. We address this gap by introducing psychological ownership as a mediator in the relationships between justice perceptions (distributive and procedural) and common work attitudes (affective commitment and job satisfaction). Our analysis of a sample of 310 non-family employees from family firms in German-speaking Switzerland and Germany reveals that psychological ownership mediates the relationships between distributive justice and affective commitment as well as job satisfaction. This leads to valuable contributions to family business research, organizational justice and psychological ownership literatures, and to practice.

Stressors, mediators, and health care outcomes of home enteral nutrition in family caregivers and their older adult care recipients

Family caregivers manage home enteral nutrition (HEN) for over 77% of an estimated 1 of every 400 Medicare recipients. Increasing usage of HEN in older adults combined with reliance on family caregivers raises concerns for the quality, outcomes, and costs of care. These concerns are relevant in light of Medicare limitations on nursing assistance and non-reimbursement for nutrition services, despite annual costs of over $600 million. This study applied stress process theories to assess stressor, mediator, and outcome variables salient to HEN and caregiving. In-home structured interviews occurred with a multi-ethnic sample of 30 caregiving dyads at 1–3 months after discharge on HEN. Care recipients were aged ≥60 (M = 68.4 years) and did not have dementia. Caregivers were aged ≥21, unpaid, and lived within 45 minutes of care recipients. Caregivers performed an average of 19.7 tasks daily for 61.9 hours weekly. Training needs were identified for 33 functional, care management, technical, and nutritional tasks. Preparedness scores were low (M = 1.73/4.0), and positively correlated with competence, self-rated quality of care and positive feelings, and negatively with overload, role captivity, and negative feelings (Ps < .05). Caregivers had multiple changes in lifestyle and dietary behaviors. Lifestyle changes positively correlated with overload, and negatively with preparedness and positive feelings. Dietary changes positively correlated with number of tasks, overload, role captivity and negative feelings, and negatively with preparedness (Ps < .01). Fifty-seven percent of caregivers aged >50 were at nutrition risk. Care recipients fared worse. Average weight change was −4.35 pounds (P < .001). Physical complications interrupted daily enteral infusions. Water intake was half of fluid need and associated with signs of dehydration (P < .001). Physical and social function was poor, with older subjects more impaired ( P < .04). Those with better prepared or less overloaded caregivers had higher functionality and QOL (P < .002). Complications, type of feeding tube, and caregiver preparedness correlated with frequency of health care utilization (Ps < .05). Efficacy of HEN in older adults requires specialized caregiver training, attention to caregivers' needs, and frequent monitoring from a highly skilled multidisciplinary team including dietitians. ^

Once a Catholic : a novel in stories and poems

"Once A Catholic" is a novel about the indelible effects of growing up Catholic. The novel is told in a series of stories and poems. The first story, "Credo," offers an overview of the rich culture of Catholicism that binds the Daley family together. "Before The Fall" recalls the safety and warmth of that Catholic faith. Subsequent stories focus on individual family members and events, and the Catholicity that lies at their core. "Holy Orders" tells the story the firstborn male child whose destination is the priesthood. "Finding Ecstasy" is a daughter's story of rebellion through sexual exploration. "Sweet Reconciliation" is the story of a search within oneself for forgiveness, the cornerstone of Catholic upbringing. "Acts of the Apostle" demonstrates the hopelessness of a faith under attack. The final story, "Holy Relics," demonstrates the never-ending desire for redemption and the important act of returning sacredness to its rightful place.

Long-term Success of Family Firms: Investigating Specific Aspects of Firm-level Entrepreneurship and Individual-level Antecedents

Long-term success of family firms is of utmost social and economic importance. Three of its determinants are in the center of this Dissertation: firmlevel entrepreneurial orientation (EO), managers' entrepreneurial behavior, and value-creating attitudes of non-family employees. Each determinant and respective research gaps are addressed by one paper of this cumulative dissertation. Referring to firm-level EO, scholars claim that EO is a main antecedent to firms' both short- and long-term success. However, family firms seem to be successful across generations despite rather low levels of EO. The first paper addresses this paradox by investigating EO patterns of long-lived family firms in three Swiss case studies. The main finding is that the key to success is not to be as entrepreneurially as possible all the time, but to continuously adapt the EO profile depending on internal and external factors. Moreover, the paper suggest new subcategories to different EO dimensions. With regard to entrepreneurial behavior of managers, there is a lack of knowledge how individual-level and organizational level factors affect its evolvement. The second paper addresses this gap by investigating a sample of 403 middle-level managers from both family and non-family firms. It introduces psychological ownership of managers as individual-level antecedent and investigates the interaction with organizational factors. As a central insight, management support is found to strengthen the psychological ownership-entrepreneurial behavior relationship. The third paper is based on the fact that employees' justice perceptions are established antecedents of value-creating employee attitudes such as affective commitment and job satisfaction. Even though family firms are susceptible to nonfamily employees´ perceptions of injustice, corresponding research is scarce. Moreover, the mechanism connecting justice perceptions and positive outcomes is still unclear. Addressing these gaps, the analysis of a sample of 310 non-family employees reveals that psychological ownership is a mediator in the relationships between distributive justice perceptions and both affective commitment and job satisfaction. Altogether, the three papers offer valuable contributions to family business literature with respect to EO, entrepreneurial behavior, and value-creating employee attitudes. Thus, they increase current understanding about important determinants of family firms' long-term success, while opening up numerous ways of future research.

Stephen Dedalus' Search for Identity in Catholic Ireland

The purpose of my research was to explore the interplay between religion and art in James Joyce’s novel, A PORTRAIT OF THE ARTIST AS A YOUNG MAN. My aim was to trace the development of the protagonist, Stephen Dedalus by analyzing how Catholicsim is an institution that forms him, yet must reject to realize his artistic potential. I researched Joyce’s background to gain an understanding of the exilic experience on the literature. Through the exilic lens, I realized that Catholicism was the predominant influence on Stephen’s need to embark on a self-imposed exile at the end of the novel. Complicating his decision is the fact that he does not stop believing in religious constructs such as heaven and hell. In conclusion I found by following his artistic longing, and turning away from the church he is committing a sin and, as a result, damning his soul.
