Higher education learner identity for successful student transitions

ABSTRACT Student success in higher education (HE) is dependent on the possession of a positive learner identity, the development of which is a complex longitudinal process of change. Exploring the growth of learner identity within the transition between school and university is therefore apposite, especially for learners from disadvantaged backgrounds who may not have sufficient cultural capital to make an easy intellectual transition from school pupil to university student. Learner identity is positively linked with both the academic and social context of learning as well as with concepts of engagement and a sense of belonging in HE. This article explores the findings of a Scottish study involving 30 students who took part in a unique widening participation model based on immersing learners in the university environment whilst still at school. Findings include evidence of the development of a transformative HE learner identity which is enabled by an immersive experience of university prior to entry. A model for HE learning identity formation is suggested. In the context of the current dialogue on fair access and widening participation to HE internationally, findings point policy makers to the benefits of long-term immersion in HE prior to entry for successful transition to university.
The Role of Aspects in Modeling Product Line Variabilities

As of today, it is unclear whether aspect-oriented modeling can benefit the model-driven development of software product lines. Although some preliminary studies exist at the requirements and implementation level that investigate the interaction of crosscutting behaviors and product-line variabilities, to the best of our knowledge these interactions at the modeling level are not yet investigated. The contribution of this work is a preliminary study of the object-oriented and aspect-oriented approaches for handling crosscutting variabilities. This study helps us identify desired characteristics of aspect-oriented modeling techniques for product lines. A pacemaker product line, extracted from the real industry case, serves as a running example to illustrate our findings.
Effects of landscape matrix on population connectivity of an arboreal mammal, Petaurus breviceps

Abstract Ongoing habitat loss and fragmentation is considered a threat to biodiversity as it can create small, isolated populations that are at increased risk of extinction. Tree‐dependent species are predicted to be highly sensitive to forest and woodland loss and fragmentation, but few studies have tested the influence of different types of landscape matrix on gene flow and population structure of arboreal species. Here, we examine the effects of landscape matrix on population structure of the sugar glider (Petaurus breviceps) in a fragmented landscape in southeastern South Australia. We collected 250 individuals across 12 native Eucalyptus forest remnants surrounded by cleared agricultural land or exotic Pinus radiata plantations and a large continuous eucalypt forest. Fifteen microsatellite loci were genotyped and analyzed to infer levels of population differentiation and dispersal. Genetic differentiation among most forest patches was evident. We found evidence for female philopatry and restricted dispersal distances for females relative to males, suggesting there is male‐biased dispersal. Among the environmental variables, spatial variables including geographic location, minimum distance to neighboring patch, and degree of isolation were the most important in explaining genetic variation. The permeability of a cleared agricultural matrix to dispersing gliders was significantly higher than that of a pine matrix, with the gliders dispersing shorter distances across the latter. Our results added to previous findings for other species of restricted dispersal and connectivity due to habitat fragmentation in the same region, providing valuable information for the development of strategies to improve the connectivity of populations in the future.
Contextual Factors Explain Risk-Seeking Preferences in Rhesus Monkeys

In contrast to humans and most other animals, rhesus macaques strongly prefer risky rewards to safe ones with similar expected value. Why macaques prefer risk while other animals typically avoid it remains puzzling and challenges the idea that monkeys provide a model for human economic behavior. Here we argue that monkeys’ risk-seeking preferences are neither mysterious nor unique. Risk-seeking in macaques is possibly induced by specific elements of the tasks that have been used to measure their risk preferences. The most important of these elements are (1) very small stakes, (2) serially repeated gambles with short delays between trials, and (3) task parameters that are learned through experience, not described verbally. Together, we hypothesize that these features will readily induce risk-seeking in monkeys, humans, and rats. Thus, elements of task design that are often ignored when comparing studies of risk attitudes can easily overwhelm basal risk preferences. More broadly, these results highlight the fundamental importance of understanding the psychological basis of economic decisions in interpreting preference data and corresponding neural measures.
Electrophysiological Evidence for the Continuous Processing of Linguistic Categories of Regular and Irregular Verb Inflection in German

A central question concerning word recognition is whether linguistic categories are processed in continuous or categorical ways, in particular, whether regular and irregular inflection is stored and processed by the same or by distinct systems. Here, we contribute to this issue by contrasting regular (regular stem, regular suffix) with semi-irregular (regular stem, irregular suffix) and irregular (irregular stem, irregular suffix) participle formation in a visual priming experiment on German verb inflection. We measured ERPs and RTs and manipulated the inflectional and meaning relatedness between primes and targets. Inflected verb targets (e.g., leite, “head”) were preceded either by themselves, by their participle (geleitet, “headed”), by a semantically related verb in the same inflection as the target (führe, “guide”) or in the participle form (geführt, “guided”), or by an unrelated verb in the same inflection (nenne, “name”). Results showed that behavioral and ERP priming effects were gradually affected by verb regularity. Regular participles produced a widely distributed frontal and parietal effect, irregular participles produced a small left parietal effect, and semi-irregular participles yielded an effect in-between these two in terms of amplitude and topography. The behavioral and ERP effects further showed that the priming because of participles differs from that because of semantic associates for all verb types. These findings argue for a single processing system that generates participle priming effects for regular, semi-irregular, and irregular verb inflection. Together, the findings provide evidence that the linguistic categories of verb inflection are processed continuously. We present a single-system model that can adequately account for such graded effects.
Preparation and Photocatalytic Activity of Potassium-Incorporated Titanium Oxide Nanostructures Produced by the Wet Corrosion Process Using Various Titanium Alloys

Nanostructured potassium-incorporated Ti-based oxides have attracted much attention because the incorporated potassium can influence their structural and physico-chemical properties. With the aim of tuning the structural and physical properties, we have demonstrated the wet corrosion process (WCP) as a simple method for nanostructure fabrication using various Ti-based materials, namely Ti–6Al–4V alloy (TAV), Ti–Ni (TN) alloy and pure Ti, which have 90%, 50% and 100% initial Ti content, respectively. We have systematically investigated the relationship between the Ti content in the initial metal and the precise condition of WCP to control the structural and physical properties of the resulting nanostructures. The WCP treatment involved various concentrations of KOH solutions. The precise conditions for producing K-incorporated nanostructured titanium oxide films (nTOFs) were strongly dependent on the Ti content of the initial metal. Ti and TAV yielded one-dimensional nanowires of K-incorporated nTOFs after treatment with 10 mol/L-KOH solution, whereas TN required a higher concentration (20 mol/L-KOH solution) to produce comparable nanostructures. The obtained nanostructures revealed a blue-shift in UV absorption spectra due to the quantum confinement effects. A significant enhancement of the photocatalytic activity was observed via the chromomeric change and the intermediate formation of methylene blue molecules under UV irradiation. This study demonstrates the WCP as a simple, versatile and scalable method for the production of nanostructured K-incorporated nTOFs to be used as high-performance photocatalysts for environmental and energy applications.
In vivo brain concentrations of N-acetyl compounds, creatine, and choline in Alzheimer disease.

BACKGROUND Alzheimer disease (AD) and normal aging result in cortical gray matter volume deficits. The extent to which the remaining cortex is functionally compromised can be estimated in vivo with magnetic resonance spectroscopic imaging. OBJECTIVE To assess the effects of age and dementia on gray matter and white matter concentrations of 3 metabolites visible in the proton spectrum: N-acetyl compounds, present only in living neurons; creatine plus phosphocreatine, reflecting high-energy phosphate metabolism; and choline, increasing with membrane synthesis and degradation. METHOD Fifteen healthy young individuals, 19 healthy elderly individuals, and 16 patients with AD underwent 3-dimensional magnetic resonance spectroscopic imaging and memory and language testing. RESULTS Gray matter N-acetyl compound concentrations (signal intensity corrected for the amount of brain tissue contributing to the magnetic resonance spectroscopic imaging signal) was significantly reduced only in patients with AD, even though both the AD and elderly control groups had substantial gray matter volume deficits relative to the young control group. Both the healthy elderly and AD groups had abnormally high gray matter creatine plus phosphocreatine concentrations. Gray matter choline concentrations were higher in the elderly than the younger controls, and even higher in the AD group than in the elderly control group. Functional significance of these findings was supported by correlations between poorer performance on recognition memory tests and lower gray matter N-acetyl compounds in elderly controls and higher gray matter creatine plus phosphocreatine and choline concentrations in patients with AD. CONCLUSION Cortical gray matter volume deficits in patients with AD are accompanied by disease-related increases in gray matter choline concentrations suggestive of cellular degeneration and reduced N-acetyl compound concentrations, with possible effects on behavioral function.
A Hidden Role of the Inactivated FANCD2: Upregulating ΔNp63

A compromised Fanconi Anemia (FA) signaling pathway, often resulting from an inactivated FANCD2, was recently recognized to contribute to the development of non-FA human tumors. However, it is largely unknown as to how an impaired FA pathway or an inactivated FANCD2 promotes tumorigenesis. Here we unexpectedly found that ΔNp63 mRNA was expressed at high levels in human cancer cells carrying an impaired FA pathway compared to the corresponding control cells carrying an intact FA pathway. This observation was recapitulated upon conditionally managing the status of FANCD2 monoubiquitination /activation in 293T cells. Importantly, ΔNp63 elevation upon FANCD2 inactivation was confirmed in human fibroblasts derived from FA patients. Moreover, we have identified a 189 bp DNA fragment downstream of the ΔNp63 promoter (P2) that can mediate the upregulation of ΔNp63 by an inactivated FANCD2, and determined that elevated ΔNp63 is high enough to promote cancer cell proliferation and metastasis. In vivo, the elevation of FAVL, a tumor promotion factor that inhibits FANCD2 activation, was found to be positively associated with ΔNp63 expression in human cancer tissues. Collectively, these results document a novel role of an inactivated FANCD2 in upregulating ΔNp63, advancing our understanding of how an impaired FA pathway contributes to the pathogenesis of human cancer.
Students’ physical education experiences in a multi-ethnic class

ABSTRACT As western countries have become increasingly diverse, education is often emphasized as one of the most important arenas for social integration. However, research within physical education over the past decades has highlighted how students with non-western backgrounds experience processes of ‘othering’, exclusion, and marginalization in the subject. In the Norwegian context, we have little knowledge about how these processes work within multi-ethnic PE lessons. In addition, scholars have pointed to the tendency of PE research on race/racism and ethnicity to focus on the minoritized ‘other’, while leaving out the complexity of the multi-ethnic encounter. By applying an intersectional lens, our aim is to investigate students’ experiences in a multi-ethnic co-educational PE context. Specifically, we ask how the students’ multiple identities may influence their experiences within PE, and what processes of inclusion and exclusion are revealed through their narratives. The study is based on ethnographic fieldwork in two PE classes, in an urban secondary school in Norway. Data for this article is drawn from one of the classes and consists of written field notes from observation of 26 PE lessons and semi-structured interviews with 11 students. Selection criteria for the interviews were based on gender, ethnic background, visible skills, and attitudes expressed towards the subject, as well as students belonging to different social groupings within the class. Data were analyzed using thematic narrative analysis. In the article, three students’ narratives are discussed. The findings indicate that, while the multi-ethnic learning context is experienced as an arena in which to develop social relations across cultural differences, the students’ stories also reveal how ethnic and cultural differences cause tensions in relation to students’ interaction during activities and in the changing room. In these tensions, power relations embedded across students’ ethnic, gender, and class identities become manifest.
Opportunities for Corrective Feedback During Study Abroad: A Mixed Methods Approach

ABSTRACT The provision of corrective feedback during oral interaction has been deemed an essential element for successful second language acquisition (Gass & Mackey, 2015a). However, corrective feedback—especially corrective feedback provided by peer interlocutors—remains understudied in naturalistic settings. The present mixed methods study aimed to identify the target and type of corrective feedback provided by both native-speaker and peer interlocutors during conversation groups while abroad. U.S. study abroad students (N = 19) recorded group conversations with native speakers (N = 10) at the beginning, middle, and end of a 6-week stay in Barcelona, Spain. Results indicate a significant decrease in the provision of corrective feedback by both native speakers and peer learners over the course of the program. Qualitative analyses revealed that both learners and natives alike engage in negotiations for meaning throughout the program, which for learners resulted in successful recall on tailor-made quizzes. The use of the first language by both the study abroad students and the native speakers promoted these opportunities in some instances. Results are discussed in terms of their contribution to the study abroad literature as well as to research into the effects of feedback on second language development.
Pain and Attention

Attention plays a pivotal role in the experience of pain and its impact upon daily activities. Accordingly, research on the interplay between attention and pain has a long scientific history. This chapter discusses the theoretical frameworks that aim to explain the relationship between attention and pain. It argues for a motivational perspective on pain that highlights the critical role of cognitive, affective, and contextual factors in explaining the interplay between attention and pain. To substantiate this argument, the chapter provides an overview of available research addressing the bottom-up capture of attention by pain and the top-down modulation (both inhibition and facilitation) of attention for pain. It concludes with guidelines and suggestions for future research and discusses clinical implications of adopting a motivational perspective on pain.
Awareness about the use, Ethics and Scope of Dental Photography among Undergraduate Dental Students Dentist Behind the lens

Aim: Evaluating the awareness of use, scope and ethics of dental photography in everyday practice among undergraduate dental students. Background: Photography often represents the best method to collect and preserve evidences. The attention towards the advanced photographic presentation in dentistry has increased significantly over the past several decades. Advancements in technology, computers, the internet and communication systems have greatly affected and shaped modern society. The main purpose of photography in dentistry is the registration of clinical information in the oral cavity. It also finds application for the purposes of dento legal documentation, to improve the learning process, communication and dental marketing. These applications improve the status of the dental practice as well as the quality of work and services. Materials and Methods: This is a cross sectional institution based study conducted among 176 undergraduate dental students. 176 undergraduate dental students of 3rd, 4th and 5th year of age group 21-25 years were included in the study. Each student was given a questionnaire. The questionnaire consisted of a set of 11 questions. Both yes or no and multiple choice questions were present. The answers were tabulated and statistically analyzed. Results: All the students in the study were found to routinely use dental photography in their regular practice.82% of the students took some form of consent from the patient before taking the photograph and 93% maintained the confidentiality if the patient in social forums, Presentations and research publications. 62% of the participants are aware of a course called dental photography and 34% have already attended a course in dental photography. Conclusion: Combining a passion for photography with a dedication to dentistry will help us to successfully record patients cases and have a better proposition in teaching, motivation, treatment and follow up.
Ultrastructural Studies on Oocyte Development and Vitellogenesis associated with Follicle Cells in Female Scapharca subcrenata (Pelecypoda: Arcidae) in Western Korea

Ultrastructural studies on oocyte development and vitellogenesis in oocytes, and the functions of follicle cells during oogenesis and oocyte degeneration were investigated to clarifyb the reproductive mechanism on vitellogenesis of Scapharca subcrenata using electron microscope observations. In this study, vitellogenesis during oogenesis in the oocytes occured by way of autosynthesis and heterosynthesis. Of two processes of vitellogenesis during oogenesis, the process of endogenous autosynthesis involved the combined activity of the Golgi complex, mitochondria and rough endoplasmic reticulum. However, the process of exogenous heterosynthesis involved endocytotic incorporation of extraovarian precursors at the basal region of the oolema of the early vitellogenic oocytes before the formation of the vitelline coat. In this study, follicle cells, which attached to the previtellogenic and vitellogenic oocytes, were easily found. In particular, the follicle cells were involved in the development of previtellogenic oocytes by the supply of nutrients, and vitellogenesis in the early and late vitellogenic oocytes by endocytosis of yolk precursors. Based on observations of follicle cells attached to degenerating oocytes after spawning, follicles of this species are involved in lysosomal induction of oocyte degeneration for the resorption phagosomes (phagolysosomes) in the cytoplasm for nutrient storage, as seen in other bivalves. In this study, the functions of follicle cells can accumulate reserves of lipid granules and glycogen particles for vitellogenesis from degenerating oocytes after spawning.
Collectivism, propensity to trust and self‐esteem as predictors of organizational citizenship in a non‐work setting

This study examined organizational citizenship of residents in a housing cooperative setting where roles were not influenced by traditional employee–employer work relationships. Results demonstrate that the individual differences of collectivism and propensity to trust predicted organizational citizenship (assessed six months later). In addition, organizational-based self-esteem fully mediated the effects of collectivism and propensity to trust on organizational citizenship, and tenure moderated the trust—self-esteem relationship. We discuss the implications of these results given the changing nature of work and the increasing importance of non-work organizations. Copyright © 2000 John Wiley & Sons, Ltd.
Plasmablasts as a biomarker for IgG4-related disease, independent of serum IgG4 concentrations

Objectives We examined the utility of circulating total and IgG4+ plasmablasts as biomarkers of diagnosis and disease activity in IgG4-related disease (IgG4-RD). Materials methods We evaluated patients with active, untreated, biopsy-proven IgG4-RD affecting various organs. Flow cytometry was used to measure total plasmablast and IgG4+ plasmablast counts by gating peripheral blood for CD19lowCD38+CD20−CD27+ cells and CD19lowCD38+CD20−CD27+IgG4+ cells. Serum IgG4 concentrations were measured by nephelometry. We compared 37 IgG4-RD patients to 35 controls, including healthy individuals (n=14) and patients with other inflammatory diseases before treatment (n=21). Results The IgG4-RD patients’ mean age was 59, and 68% were male. Fourteen patients (38%) had three or more organs involved. The IgG4-RD patients had substantially elevated total plasmablast counts (median 4698/mL, range 610–79524/mL) compared to both untreated disease controls (median 592/mL, range 19–4294/mL; p < 0.001) and healthy controls (median 94/mL, range 1–653/mL; p < 0.001). Thirteen IgG4-RD patients (36%) had normal serum IgG4 concentrations (mean 60 mg/dL, range 5–123 mg/dL, normal <135 mg/dL). However, the median plasmablast count was not significantly lower in that subset with normal serum IgG4 concentrations (3784/mL) compared to those with elevated serum IgG4 (5155/mL) (p = 0.242). Among the 12 rituximab (RTX)-treated patients, the median plasmablast level during disease flare was 6356/mL (range 1123–41589/mL), declining to 1419/mL (range 386/mL–4150/mL) during remission (p < 0.01). Conclusions Circulating plasmablasts are elevated in active IgG4-RD, even in patients with normal serum IgG4 concentrations. Plasmablast counts are a potentially useful biomarker for diagnosis, assessing response to treatment, and determining the appropriate time for re-treatment.
Directionally Reinforced Random Walks

Abstract This paper introduces and analyzes a class of directionally reinforced random walks. The work is motivated by an elementary model for time and space correlations in ocean surface wave fields. We develop some basic properties of these walks. For instance, we investigate recurrence properties and give conditions under which the limiting continuous versions of the walks are Gaussian diffusion processes.
