Plasma functionalization of textiles: Specifics and possibilities

Plasma technology offers many interesting possibilities for the production of high-value-added textiles. Nevertheless, textiles can have a considerable structural and chemical complexity, and their properties must be taken into account for the implementation of plasma processes. The influences of some of these properties are highlighted through several examples of recent interesting applications, such as the metallization of polyester yarns, the enhancement of fabric moisture wicking and the surface functionalization with plasma polymerizatio

Aboriginal Well-being in Four Countries: An Application of the UNDP’s Human Development Index to Aboriginal People in Australia, Canada, New Zealand, and the United States

An adaptation of the UNDP’s Human Development Index is used to compare the wellbeing of Aboriginal and non-Aboriginal populations in Australia, Canada, New Zealand, and the United States between 1991 and 2001. Using Census education and income measures, and official estimates of life expectancy, we find that despite improvements in the overall well-being of Aboriginal populations, disparities between Aboriginal and non-Aboriginal people widened in some cases. Aboriginal people in most of these countries fell behind in educational attainment, compared to non-Aboriginal populations. Incomes improved over the entire period, but fell in most of these countries between 1991 and 1996. Overall, Aboriginal populations in Australia and New Zealand had lower scores than in Canada and the U.S. However, whereas the Maori scores improved considerably between 1991 and 2001, those of the Australian Aboriginal population did not. American Indians and Alaska natives had the highest overall development scores, and smallest gaps between Aboriginal and non-Aboriginal people were found in the U.S

Exploring psychological mechanisms of collective action: Does relevance of group identity influence how people cope with collective disadvantage?

Two studies examined how the relevance of group identity influences two psychological mechanisms of collective action: Emotion- and problem-focused coping with collective disadvantage. Extending Van Zomeren, Spears, Fischer, and Leach's (2004) integrative theoretical model of coping with collective disadvantage, we predicted that when group identity is more relevant to disadvantaged group members, it increases their collective action tendencies through their feelings of group-based anger about their group's disadvantage. When group identity is less relevant and hence emotion-focused coping processes are less likely, group-efficacy beliefs become more predictive of disadvantaged group members' collective action tendencies because people focus more instrumentally on whether collective action will be effective (and benefit them) or not. A field study and a follow-up experiment both showed that the relevance of group identity facilitated emotion-focused coping and moderated problem-focused coping with collective disadvantage. We discuss these results in terms of two distinct psychological mechanisms of collective action

Sulfatase‐mediated manipulation of the astrocyte‐Schwann cell interface

Schwann cell (SC) transplantation following spinal cord injury (SCI) may have therapeutic potential. Functional recovery is limited however, due to poor SC interactions with host astrocytes and the induction of astrogliosis. Olfactory ensheathing cells (OECs) are closely related to SCs, but intermix more readily with astrocytes in culture and induce less astrogliosis. We previously demonstrated that OECs express higher levels of sulfatases, enzymes that remove 6‐O‐sulfate groups from heparan sulphate proteoglycans, than SCs and that RNAi knockdown of sulfatase prevented OEC‐astrocyte mixing in vitro. As human OECs are difficult to culture in large numbers we have genetically engineered SCs using lentiviral vectors to express sulfatase 1 and 2 (SC‐S1S2) and assessed their ability to interact with astrocytes. We demonstrate that SC‐S1S2s have increased integrin‐dependent motility in the presence of astrocytes via modulation of NRG and FGF receptor‐linked PI3K/AKT intracellular signaling and do not form boundaries with astrocytes in culture. SC‐astrocyte mixing is dependent on local NRG concentration and we propose that sulfatase enzymes influence the bioavailability of NRG ligand and thus influence SC behavior. We further demonstrate that injection of sulfatase expressing SCs into spinal cord white matter results in less glial reactivity than control SC injections comparable to that of OEC injections. Our data indicate that sulfatase‐mediated modification of the extracellular matrix can influence glial interactions with astrocytes, and that SCs engineered to express sulfatase may be more OEC‐like in character. This approach may be beneficial for cell transplant‐mediated spinal cord repair. GLIA 2016 GLIA 2017;65:19–3

Genetic and Environmental Influences on Individual Differences in Attitudes Toward Homosexuality: An Australian Twin Study

Previous research has shown that many heterosexuals hold negative attitudes toward homosexuals and homosexuality (homophobia). Although a great deal of research has focused on the profile of homophobic individuals, this research provides little theoretical insight into the aetiology of homophobia. To examine genetic and environmental influences on variation in attitudes toward homophobia, we analysed data from 4,688 twins who completed a questionnaire concerning sexual behaviour and attitudes, including attitudes toward homosexuality. Results show that, in accordance with literature, males have significantly more negative attitudes toward homosexuality than females and non-heterosexuals are less homophobic than heterosexuals. In contrast with some earlier findings, age had no significant effect on the homophobia scores in this study. Genetic modelling showed that variation in homophobia scores could be explained by additive genetic (36%), shared environmental (18%) and unique environmental factors (46%). However, corrections based on previous findings show that the shared environmental estimate may be almost entirely accounted for as extra additive genetic variance arising from assortative mating for homophobic attitudes. The results suggest that variation in attitudes toward homosexuality is substantially inherited, and that social environmental influences are relatively minor

Enhancing Employability for Autistic Graduates: Using TRIZ Theory to Design Virtual Reality Solutions for Fostering Inclusive Communications in Workplace Environments

The underemployment of post-secondary graduates with autism (AP-PSD) is a critical concern. This issue often stems from difficulties in workplace integration and communication. This research explores the potential of virtual reality (VR) systems to alleviate these challenges by simulating work environments. The methodology, rooted in the TRIZ Theory, a problem-solving algorithm, refines the use of VR systems for enhanced adaptability and efficiency. The primary objectives include enhancing employers\u27 understanding of AP-PSD-related issues and identifying significant workplace challenges faced by AP-PSDs. Through literature reviews, surveys, and focus groups, the study investigates the factors impacting AP-PSDs and identifies key components to develop a more effective VR system to support their workplace integration

Guidance on patient Identification and Administration of Recombinant Human Activated protein C for the Treatment of Severe Sepsis

Approximately one-third of cases of severe sepsis result in death. Endogenous activated protein C (ApC) plays a key role in the regulation of the inflammation, fibrinolysis and coagulation associated with severe sepsis. In a recently published phase III trial, protein C Worldwide Evaluation in Severe Sepsis (pROWESS), intravenous administration of recombinant human ApC (rhApC) 24 µg/kg/h for 96 h to patients with severe sepsis resulted in a 6.1% reduction in absolute mortality and a 19.4% reduction in the relative risk of death from any cause within 28 days (number needed to treat = 16). This dose is now being applied in clinical practice

Virtual reality at workplace for autistic employees: Preliminary results of physiological-based well-being experience

Emotional health problems in the workplace often hinder the integration and retention of autistic employees (AE), a challenge identified in many sectors. Recent literature highlights the consequences of these problems, such as burnout leading to reduced productivity and resignation. Previous research supports the effectiveness of virtual reality (VR) for training a variety of specific skills (e.g. riding a bus or plane travel), as well as more complex social skills, such as emotion recognition and functional communication. In addition, existing studies on using physiological self-monitoring in AE training offer a promising approach to promoting improved emotional health. The present paper reports on implementing a VR system that simulates workplace training and integration and enables real-time monitoring of three physiological signals, in five post-secondary autistic students. Using an Oculus Quest 2 and non-clinical grade sensors, the researchers delivered the VR intervention over three days to each participant. At the end of these interventions, the researchers measured the perceived satisfaction of these integrated systems, based on several technological criteria, on a 5-point scale. The integrated system received an overall rating of 4, suggesting its likelihood of acceptance and use. A preliminary analysis of a participant’s physiological responses to this VR intervention is also presented. This preliminary report suggests the efficacy of a VR workplace simulation and physiological self-monitoring in promoting emotional well-being and basic task training for post-secondary AE. The researchers’ observations and the proposal of a theoretical framework to enhance real-time emotional communication based on physiological markers for AE are also discussed
