The fantastic in the family sagas : implications for saga authorship

There is increasing acceptance that characterisation in the family sagas is complex enough to include the subtle incorporation of protagonists’ inner lives. Thus, despite saga authors’ apparent desire to pass on traditional stories, saga characterization brings with it the possibility of a connection between the medieval author and the early Icelandic community represented in the sagas, a break in the saga code of objective narration that adds further weight to recent arguments that saga authorship was conceived in broader terms than merely the preservation of oral tales. One such break in objectivity occurs in the range of responses to the fantastic, when characters are forced to interpret the supernatural or strange events in their lives. At such times, the author allows glimpses of the inner lives of characters, focussing our attention on the way in which characters perceived and dealt with extraordinary occurrences, but also highlighting and thematising the distinctive social context of the early Icelandic community.

UpaG, a new member of the Trimeric Autotransporter family of Adhesins in Uropathogenic Escherichia coli

The ability of Escherichia coli to colonize both intestinal and extraintestinal sites is driven by the presence of specific virulence factors, among which are the autotransporter (AT) proteins. Members of the trimeric AT adhesin family are important virulence factors for several gram-negative pathogens and mediate adherence to eukaryotic cells and extracellular matrix (ECM) proteins. In this study, we characterized a new trimeric AT adhesin (UpaG) from uropathogenic E. coli (UPEC). Molecular analysis of UpaG revealed that it is translocated to the cell surface and adopts a multimeric conformation. We demonstrated that UpaG is able to promote cell aggregation and biofilm formation on abiotic surfaces in CFT073 and various UPEC strains. In addition, UpaG expression resulted in the adhesion of CFT073 to human bladder epithelial cells, with specific affinity to fibronectin and laminin. Prevalence analysis revealed that upaG is strongly associated with E. coli strains from the B2 and D phylogenetic groups, while deletion of upaG had no significant effect on the ability of CFT073 to colonize the mouse urinary tract. Thus, UpaG is a novel trimeric AT adhesin from E. coli that mediates aggregation, biofilm formation, and adhesion to various ECM proteins.

The hereditary transmission of the glutathione transferase hGSTT1-1 conjugator phenotype in a large family

The polymorphism of human glutathione transferase hGSTT1-1 is expressed in three phenotypes. Experimentally, individuals can be classified as non-conjugators, low conjugators and 'high' conjugators depending on the enzyme activity in blood towards methylene chloride using a gas chromatographic assay. Non-conjugators do not have a functional hGSTT1 gene; however, little is known about the molecular basis of the three conjugator phenotypes. The higher hGSTT1-1 activity in high conjugators may be the result of enzyme induction or be genetically determined. Twenty-nine members of a large family, including three generations were phenotyped and genotyped with respect to hGSTT1-1. The hGSTT1-1 enzyme activity of high conjugators was twice as high as that of low conjugators. The distribution of hGSTT1-1 phenotypes strongly indicates a Mendelian intermediary inheritance, in which a gene-dosage effect results in a doubled enzyme expression in the presence of two functional alleles. The Mendelian intermediary inheritance is further supported by the findings of a semiquantitative polymerase chain reaction method designed to distinguish the three genotypes of hGSTT1 for rapid screening of large study groups.

Evidence of associations between cytokine gene polymorphisms and quality of life in patients with cancer and their family caregivers

PURPOSE/OBJECTIVES: To identify latent classes of individuals with distinct quality-of-life (QOL) trajectories, to evaluate for differences in demographic characteristics between the latent classes, and to evaluate for variations in pro- and anti-inflammatory cytokine genes between the latent classes. DESIGN: Descriptive, longitudinal study. SETTING: Two radiation therapy departments located in a comprehensive cancer center and a community-based oncology program in northern California. SAMPLE: 168 outpatients with prostate, breast, brain, or lung cancer and 85 of their family caregivers (FCs). METHODS: Growth mixture modeling (GMM) was employed to identify latent classes of individuals based on QOL scores measured prior to, during, and for four months following completion of radiation therapy. Single nucleotide polymorphisms (SNPs) and haplotypes in 16 candidate cytokine genes were tested between the latent classes. Logistic regression was used to evaluate the relationships among genotypic and phenotypic characteristics and QOL GMM group membership. MAIN RESEARCH VARIABLES: QOL latent class membership and variations in cytokine genes. FINDINGS: Two latent QOL classes were found: higher and lower. Patients and FCs who were younger, identified with an ethnic minority group, had poorer functional status, or had children living at home were more likely to belong to the lower QOL class. After controlling for significant covariates, between-group differences were found in SNPs in interleukin 1 receptor 2 (IL1R2) and nuclear factor kappa beta 2 (NFKB2). For IL1R2, carrying one or two doses of the rare C allele was associated with decreased odds of belonging to the lower QOL class. For NFKB2, carriers with two doses of the rare G allele were more likely to belong to the lower QOL class. CONCLUSIONS: Unique genetic markers in cytokine genes may partially explain interindividual variability in QOL. IMPLICATIONS FOR NURSING: Determination of high-risk characteristics and unique genetic markers would allow for earlier identification of patients with cancer and FCs at higher risk for poorer QOL. Knowledge of these risk factors could assist in the development of more targeted clinical or supportive care interventions for those identified.

Conserved signaling through vascular endothelial growth (VEGF) receptor family members in murine lymphatic endothelial cells

Lymphatic vessels guide interstitial fluid, modulate immune responses by regulating leukocyte and antigen trafficking to lymph nodes, and in a cancer setting enable tumor cells to track to regional lymph nodes. The aim of the study was to determine whether primary murine lymphatic endothelial cells (mLECs) show conserved vascular endothelial growth factor (VEGF) signaling pathways with human LECs (hLECs). LECs were successfully isolated from murine dermis and prostate. Similar to hLECs, vascular endothelial growth factor (VEGF) family ligands activated MAPK and pAkt intracellular signaling pathways in mLECs. We describe a robust protocol for isolation of mLECs which, by harnessing the power of transgenic and knockout mouse models, will be a useful tool to study how LEC phenotype contributes to alterations in lymphatic vessel formation and function.

Connecting the person with dementia and family : a feasibility study of a telepresence robot

Background Maintenance of communication is important for people with dementia living in long-term care. The purpose of this study was to assess the feasibility of using “Giraff”, a telepresence robot to enhance engagement between family and a person with dementia living in long-term care. Methods A mixed-methods approach involving semi-structured interviews, call records and video observational data was used. Five people with dementia and their family member participated in a discussion via the Giraff robot for a minimum of six times over a six-week period. A feasibility framework was used to assess feasibility and included video analysis of emotional response and engagement. Results Twenty-six calls with an average duration of 23 mins took place. Residents showed a general state of positive emotions across the calls with a high level of engagement and a minimal level of negative emotions. Participants enjoyed the experience and families reported that the Giraff robot offered the opportunity to reduce social isolation. A number of software and hardware challenges were encountered. Conclusions Participants perceived this novel approach to engage families and people with dementia as a feasible option. Participants were observed and also reported to enjoy the experience. The technical challenges identified have been improved in a newer version of the robot. Future research should include a feasibility trial of longer duration, with a larger sample and a cost analysis.

Domestic and family violence

This chapter introduces domestic and family violence. It defines the terms and the types of violence they encompass, and summarizes patterns in perpetration and victimisation. The chapter reviews the historical development of domestic and family violence as recognizable social problems. It also explains how domestic violence and family violence are shaped by gender norms. Finally, it explains some key differences between these and other crimes.

The impact of work-family programs on the relationship between gender diversity and performance

Work–family programs signal an employer's perspective on gender diversity to employees, and can influence whether the effects of diversity on performance are positive or negative. This article tests the interactive effects of nonmanagement gender diversity and work–family programs on productivity, and management gender diversity and work–family programs on financial performance. The predictions were tested in 198 Australian publicly listed organizations using primary (survey) and secondary (publicly available) data based on a two-year time lag between diversity and performance. The findings indicate that nonmanagement gender diversity leads to higher productivity in organizations with many work–family programs, and management gender diversity leads to lower financial performance in organizations with few work–family programs. The results suggest different business cases at nonmanagement and management levels for the adoption of work–family programs in gender-diverse organizations.

To be well is to be not unwell : the new battleground inside our children’s heads

A number of factors are thought to increase the risk of serious psychiatric disorder, including a family history of mental health issues and/or childhood trauma. As a result, some mental health advocates argue for a pre-emptive approach that includes the use of powerful anti-psychotic medication with young people considered at-risk of developing bipolar disorder or psychosis. This controversial approach is enabled and, at the same time, obscured by medical discourses that speak of promoting and maintaining youth “wellbeing”, however, there are inherent dangers both to the pre-emptive approach and in its positioning within the discourse of wellbeing. This chapter critically engages with these dangers by drawing on research with “at-risk” children and young people enrolled in special schools for disruptive behaviour. The stories told by these highly diagnosed and heavily medicated young people act as a cautionary tale to counter the increasingly common perception that pills and “Dr Phil’s” can cure social ills.

The special branch : governing mentalities through alternative-site placement

"…one should try to locate power at the extreme points of its exercise, where it is always less legal in character." (Foucault, 1980, p.97) Studies of schooling practices as techniques deriving from a particular art of governing that Foucault (2003b) called ‘governmentality’ have shown how psychopathologising discourses work to construct particular student-subjects and legitimise various practices of exclusion (Gram, 2007b). Here I extend this work to consider the use of alternative-site placement as an intensification in response to governmentality being put ‘at risk’. Governing ‘at a distance’ conjures an illusion of individual freedom which relies on the production of subjects who ‘choose’ to make choices that are consistent with the aspirations of government. In this chapter, it is argued that the designation of a child as ‘disorderly’ legitimises the intrusion of state into the private domain of the family via the Trojan horse of early intervention. This is enabled by the psy-sciences, whose technologies and aims amount to the moral retraining of ‘improper’ future-citizens who, in choosing to choose otherwise, threaten to make visible invisible relations of power. Alternative-site placement in special schools running intensive behaviour modification programs allows for a ‘redoubled insistence’ (Ewald, 1992) of these norms and limits that a ‘disorderly’ child threatens to transgress.

Shifting from production to purpose : facilitating design-led change in a small family-owned enterprise

This research was embedded as a Design-led Innovation catalyst within a family-owned small business, to explore the application of a design program to achieve organizational change. Based on the findings two new models for increasing design integration within an organisation were proposed, establishing a range of pre-requisites needed for a firm to progress. Struggling firms may leverage their use of design and strategy by embedding a catalyst in a new cross-disciplinary role providing the necessary internal assistance. The study demonstrated that even non-design or strategy-inclined family-owned SMEs could benefit from embarking on a design-led journey to boost their competitive preparedness.

Family structure and change through middle childhood : the impact on children's adjustment and achievement

This research project investigated the influence of family transitions on children's adjustment and school achievement across the primary school years, in single-parent, re-partnered and two-parent families. The quality of children's relationships with parents, teachers and peers were predictive of more positive outcomes, regardless of family structure. The research analysed data from the Kindergarten Cohort participating in Growing Up in Australia: The Longitudinal Study of Australian Children. Across the age span of the children studied, cumulative effects of any residential or school changes, or decreased family income, associated with family transitions, were more likely to predict poorer child outcomes in behaviour adjustment and school achievement.

Work and family : the perception of balance among female teachers in northern Malaysia

Women’s participation in paid employment has become a common scenario even in non-western developing countries. For example in Malaysia, the trend is growing although the traditional gender role remains strong in Malaysian society. Even though working, women are still expected to assume major responsibilities at home. Thus, as opposed to men, women in this society face the challenge to satisfactorily balance work and family. This study was carried out to explore how Malaysian women perceive the meaning of a balanced work-family life. Sampling women teachers, the interview findings revealed that work-family balance was mainly perceived in terms of an individual’s ‘ability to fulfill role obligation’ appropriately in both the work and family domains. A few participants also viewed balance in the context of role satisfaction and role interference. Overall, the results support the assumption in the literature that perceptions of work-family experience are not universal, rather, the construct of work-family balance is culture-specific.
