The collection of this specimen is a new state record for Missouri and represents a significant range extension south and westward for this species

Influence of cell surface characteristics on adhesion of Saccharomyces cerevisiae to the biomaterial hydroxylapatite

The influence of the physicochemical properties of biomaterials on microbial cell adhesion is well known, with the extent of adhesion depending on hydrophobicity, surface charge, specific functional groups and acid–base properties. Regarding yeasts, the effect of cell surfaces is often overlooked, despite the fact that generalisations may not be made between closely related strains. The current investigation compared adhesion of three industrially relevant strains of Saccharomyces cerevisiae (M-type, NCYC 1681 and ALY, strains used in production of Scotch whisky, ale and lager, respectively) to the biomaterial hydroxylapatite (HAP). Adhesion of the whisky yeast was greatest, followed by the ale strain, while adhesion of the lager strain was approximately 10-times less. According to microbial adhesion to solvents (MATS) analysis, the ale strain was hydrophobic while the whisky and lager strains were moderately hydrophilic. This contrasted with analyses of water contact angles where all strains were characterised as hydrophilic. All yeast strains were electron donating, with low electron accepting potential, as indicated by both surface energy and MATS analysis. Overall, there was a linear correlation between adhesion to HAP and the overall surface free energy of the yeasts. This is the first time that the relationship between yeast cell surface energy and adherence to a biomaterial has been described

Digital, material and networked: some emerging themes for SET education

Boundaries between the digital and material worlds are becoming blurred as the internet increasingly connects us to things as well as people and information. This is increasingly relevant to education as initiatives which significantly combine digital and material elements in networks are becoming a reality for Science, Engineering and Technology (SET) learning. Our paper reports on the initial findings of a project to carry out a ‘state of the art’ review of literature to establish the key themes, opportunities and obstacles that are emerging from the development and use of these ‘hybrid’ systems in learning. We wanted to explore the extent to which this new domain of study is being reported in the literature and to identify work representative of this area. Our aim was to investigate the depth of research in this area by going beyond the technologically descriptive to focus on pedagogical and organisational issues raised in the literature. To identify the state of current research in the area we carried out a systematic search of databases of Science, Engineering and Technology education literature. We found 808 papers relating to the hybrid learning initiatives we are interested in, of which the majority, 81%, involved the Engineering and Technology disciplines while 6.8% related to Science. The vast majority of papers referred to remote laboratories and most of these were concerned with describing the technologies involved. In order to explore issues emerging from the research, we carried out an in-depth text review of a particular subset of the papers found that focussed on pedagogical issues. The three main themes that emerged were: the importance of real data and authenticity in learning; the importance of a sense of presence (e.g. telepresence, social presence and/or immersion) and the locus of control in, and responsiveness of, a hybrid system. We conclude that these new digital ‘hybrid’ pedagogies offer a lens with which to view both the more traditional material pedagogies, e.g. laboratory-based learning, and purely digital pedagogies, e.g. virtual labs. Finally, issues of authenticity, presence and control/responsiveness will be of increasing pedagogical importance to other ‘hybrid’ systems, such as those involving ubiquitous computing

The Role of Performance Anxiety Within the Music Therapist

The purpose of this study was to examine the manifestation of anxiety, the role it plays in the life and practice of the music therapist, as well as exploring the techniques and exercises utilized by the therapist for this or her own care. This explorative research study used a survey approach to gather qualitative data based on both practicing music therapists and music therapy students’ perceptions and experiences related to performance anxiety within their training and clinical work. A total of 100 surveys were completed online by music therapy students, interns, novice clinicians, as well as seasoned music therapists and was then analyzed by the researcher to find what factors contribute to anxiety within the profession of music therapy. The factors explored were interpersonal skill, ability to transition through interventions, and musical ability, with the addition of the participant’s ability to contribute their own opinion. In some cases, participants voiced potential issues of anxiety beyond the clinical setting. Performance anxiety can affect an individual in their ability to complete certain skills and tasks; it can manifest through combinations of affective, cognitive, somatic, and behavioral symptoms and it can have a direct impact on the therapeutic process and the client-therapist relationship (Kenny, 2011). After a review of literature, it became apparent that the research and material relating to the dynamic of stress and anxiety within the clinician and the clinical setting is scarce. In addition to the limitation of resources on the subject, a large number of the sample group found that anxiety does exist within the day-to-day clinical work and that it is a common issue within the developing practice of music therapy. The study found that performance anxiety might be more common in the field than it is accounted for especially within the student, intern, and novice clinician

Evaluating the Constitutionality of Marital Status Classifications in the Regulation of Posthumous Reproduction and Postmortem Sperm Retrieval

In Eisenstadt v. Baird, the Supreme Court held that a state law prohibiting the provision of contraceptives to unmarried persons violated the Fourteenth Amendment’s rational basis test because of the disparate treatment it afforded to married and unmarried individuals. Eisenstadt stands for an individual’s right to make their own procreative decisions, free from governmental intrusions which impose arbitrary classifications on privacy and freedom. This Note focuses on posthumous reproduction and, more specifically, postmortem sperm retrieval: the process of using a deceased male’s frozen sperm after his death to produce his biological children at the request of his spouse or intimate partner. It provides a survey of judicial decisions relating to assisted reproductive technology, posthumous reproduction, and the constitutional right to privacy as it relates to procreative decision-making, as well as model statutes, state laws, and institutional guidelines that seek to regulate posthumous reproduction. Ultimately, this Note argues that judicial decisions, legislation, and medical facility regulations or policies that prohibit unmarried partners from posthumously reproducing with their deceased partner’s gametes on the basis of their marital status are unconstitutionally discriminatory

Pregnancy, prison and perinatal outcomes in New South Wales, Australia: a retrospective cohort study using linked health data

BACKGROUND Studies from the United States and the United Kingdom have found that imprisoned women are less likely to experience poorer maternal and perinatal outcomes than other disadvantaged women. This population-based study used both community controls and women with a history of incarceration as a control group, to investigate whether imprisoned pregnant women in New South Wales, Australia, have improved maternal and perinatal outcomes. METHODS Retrospective cohort study using probabilistic record linkage of routinely collected data from health and corrective services in New South Wales, Australia. Comparison of the maternal and perinatal outcomes of imprisoned pregnant women aged 18-44 years who gave birth between 2000-2006 with women who were (i) imprisoned at a time other than pregnancy, and (ii) community controls. OUTCOMES OF INTEREST onset of labour, method of birth, pre-term birth, low birthweight, Apgar score, resuscitation, neonatal hospital admission, perinatal death. RESULTS Babies born to women who were imprisoned during pregnancy were significantly more likely to be born pre-term, have low birthweight, and be admitted to hospital, compared with community controls. Pregnant prisoners did not have significantly better outcomes than other similarly disadvantaged women (those with a history of imprisonment who were not imprisoned during pregnancy). CONCLUSIONS In contrast to the published literature, we found no evidence that contact with prison health services during pregnancy was a "therapunitive" intervention. We found no association between imprisonment during pregnancy and improved perinatal outcomes for imprisoned women or their neonates. A history of imprisonment remained the strongest predictor of poor perinatal outcomes, reflecting the relative health disadvantage experienced by this population of women.This work was undertaken with funding from the National Health and Medical Research Council of Australia.

Expectations and Experiences of Fathers Who Have Parented Children With and Without Intellectual Disabilities

The parenting experience is as diverse as the children parented. Each child has diverse personality traits requiring flexibility and specificity in parenting strategy. This need for flexibility and specificity is more complex when one or more children within a family has an intellectual disability. Although research in this area is abundant, investigators have historically focused on mothers\u27 attitudes, beliefs, and behaviors to represent the entire family (Essex, Seltzer, & Krauss, 2001; Greenberg, 2002) rather than focusing on fathers and their caregiving relationships with their children in need of malleable but consistent parenting. Using a qualitative descriptive design, this qualitative study explored expectations and subsequent experiences of men who have fathered children with and without intellectual disabilities. The investigator collected data through face-to-face semistructured interviews with 8 fathers in Tennessee. During these interviews fathers discussed each of their children, specifically their expectations of and experiences with their children prior to birth, reactions to the differences among their children, getting through the day, and their responsibilities in teaching each child. NVivo 9.0 data management software was used. Four main themes were inductively derived from the data: Learning to Dance in the Rain, Just Do What Needs Doing, The Power of Patience, and Nurturing Uniqueness. These themes contribute to nursing knowledge by delineating the perspectives of men as they father children of differing intelligences. The results from this study suggest strategies for educators and practicing healthcare professionals working with fathers in similar situations to increase mindfulness of this all-important relationship between fathers and their children with differing intellectual capacities; the investigator also proposes areas of continued research in this field
