Studying parental involvement and university access and choice: An ‘interacting multiple capitals’ model

Capital-embedded parental involvement in education is essential in enhancing university enrolment and maximising the educational potentials for equality and excellence. Previous studies in this field have mainly utilised Perna's (2000, 2006) model, which defines parental involvement as social capital and identifies the additive influences of different types of capital (including social, economic and cultural capital) on university access and choice. Yet, little research to date theorises and disaggregates the interplay among various types of capital as well as the multiplicative capital effects on enrolment. This study addressed this gap. We proposed an ‘interacting multiple capitals’ (IMC) model and hypothesised that parental social capital could moderate the effects of cultural and economic capital on entry to university. To validate the model, a pilot survey was administered to 216 university students of Korean ethnicity in China and investigated the models of involvement adopted by Korean parents in the context of the increasing labour mobility of the Korean adult population. Moderated multiple regression analysis was employed and the results confirmed the hypothesis that capital effects upon university access and choice were multiplicative in nature, with social capital moderating the cultural capital influence on students’ educational aspirations. The study findings show that the interaction of various types of capital variables is sufficiently statistically significant to warrant future research and policy and practical discussion of how to promote parental involvement in university preparation and planning.
The Effects of Professors’ Race and Clothing Style on Student Evaluations

Abstract:This study examined the effects of professors’ race and clothing style on student evaluations. Students were randomly assigned to one of four conditions in which they received a photograph and description of a professor. The only difference between conditions was the photograph, which systematically varied race (Black or White) and clothing style (casual or formal). Both Black and White students rated the Black professor less favorably than the White professor. Students trusted the Black professor more when he was pictured in formal compared to casual clothing, while the reverse was true for the White professor. The authors’ results support previous research showing that Black professors have a significant disadvantage in the student evaluation process when compared to White professors.
Time and Performance Pressure

Abstract. Time pressure and performance pressure are among the most crucial job demands of today’s workforce. However, the literature on psychological stress barely distinguishes between these constructs. Therefore, we aimed to examine time pressure and performance pressure as two qualitatively different job demands in terms of unique moderators for both demands. We investigated whether time control would moderate the relationship between time pressure and both emotional exhaustion and work engagement. As a vulnerability factor for dealing with performance pressure, we investigated perfectionism. The cross-sectional data of 167 employees showed that time control was a significant moderator of the stress–strain relationship, but only for time pressure. By contrast, perfectionism acted as a personal risk factor only for performance pressure, strengthening the negative impact of performance pressure on strain. Our findings suggest that dealing with time and performance pressure seems to be affected by differ.
Bergman approximations of harmonic maps into the space of Kahler metrics on toric varieties

We generalize the results of Song-Zelditch on geodesics in spaces of Kahler metrics on toric varieties to harmonic maps of any compact Riemannian manifold with boundary into the space of Kahler metrics on a toric variety. We show that the harmonic map equation can always be solved and that such maps may be approximated in the C^2 topology by harmonic maps into the spaces of Bergman metrics. In particular, WZW maps, or equivalently solutions of a homogeneous Monge-Ampere equation on the product of the manifold with a Riemann surface with S^1 boundary admit such approximations. We also show that the Eells-Sampson flow on the space of Kahler potentials is transformed to the usual heat flow on the space of symplectic potentials under the Legendre transform.
Nursing within primary care settings in Atlantic Canada: a research practicum

Background: Newfoundland and Labrador (NL) ranks the highest in Canada for prevalence of chronic diseases and risk factors for chronic disease. To address this health system issue, the Government of NL has committed to primary healthcare reform, which includes implementing interdisciplinary team-based models of primary care. Successful integration of Nurse Practitioners (NP), Registered Nurses (RN), and Licensed Practical Nurses (LPN) into primary care teams requires better understanding of their current roles in primary care, barriers and facilitators of role optimization, and nursing contributions to patient and system-level outcomes. Purpose: The goal of this Master of Nursing (MN) research practicum project was to develop quantitative research skills by engaging in a variety of nursing research activities, which included examining and synthesizing the current state of knowledge related to nursing within primary care settings in Atlantic Canada, and engaging in knowledge translation activities. Methods: A scoping review of literature related to nursing in primary care settings in Atlantic Canada was conducted using Joanna Briggs Institute (JBI) methodology. The review was guided by the Nursing Role Effectiveness Model. A scoping review manuscript was prepared and submitted to the Canadian Journal of Nursing Research. Abstracts were submitted for oral presentations to three conferences taking place during Spring and Summer 2017, including the Community Health Nurses of Canada Conference, Primary Healthcare Partnership Forum, and Eastern Health Nursing Education and Research Council Nursing Research Symposium. In addition, a reflection article of research experiences was submitted to the Canadian Nurse. Results: A total of 20 articles met inclusion criteria and were reviewed. Approximately half of these articles discussed RNs and half discussed NPs in primary care settings. No literature focused on LPNs. Four studies were conducted in NL. Emphasis on interdisciplinary collaboration was evident across studies. The function of nurses within teams was found to be limited by institutional constraints and influence of other providers. Roles of RNs and NPs in primary care settings consisted primarily of chronic disease management, education, and health promotion. Primary care settings that incorporate nurses were associated with positive patient health outcomes, improved access to services, and high patient satisfaction. Conclusions: Emerging literature demonstrates the effectiveness of NPs and RNs in primary care settings across Atlantic Canada. However, there is a need to clarify the roles of NPs, RNs, and LPNs with respect to chronic disease management, health promotion, and preventive care within these settings. There is considerable opportunity for future research to investigate specific attributes of nursing within primary care teams that result in high-quality patient and system-level outcomes.
Openness and Postsecondary Academic Performance: A Meta-Analysis of Facet-, Aspect-, and Dimension-Level Correlations

Openness to experience has often been linked to academic achievement because it subsumes traits such as curiosity, open-mindedness, thoughtfulness, and intellectuality. However, recent meta-analyses have reported rather small true correlation estimates. In this article, we first provide a comprehensive rationale for a relationship between openness and academic performance with a distinct focus on specific components of openness (i.e., facets and aspects). We then extend prior research by presenting our own meta-analysis (k = 28, N = 5,861) on the relationship between 6 openness facets and postsecondary academic performance. Furthermore, we report results from meta-analytic structural equation modeling (k = 19, N = 3,627) that describe the effects of 2 openness aspects, which form an intermediate construct-level between dimension and facets, on academic achievement. Finally, we investigate 2 possible moderators in a dimension-level meta-analysis (k = 149, N = 50,449). Overall, our findings suggest that (a) only 2 openness facets are positive predictors of academic performance, (b) the 2 openness aspects have contrary effects on academic achievement, and (c) the correlation between openness and academic performance is moderated by openness scales and academic majors. We conclude that the true potential of openness for predicting academic performance is concealed within the heterogeneity of the construct and discuss according perspectives for future research.
HC-MAC: A Hardware-Constrained Cognitive MAC for Efficient Spectrum Management

Radio spectrum resource is of fundamental importance for wireless communication. Recent reports show that most available spectrum has been allocated. While some of the spectrum bands (e.g., unlicensed band, GSM band) have seen increasingly crowded usage, most of the other spectrum resources are underutilized. This drives the emergence of open spectrum and dynamic spectrum access concepts, which allow unlicensed users equipped with cognitive radios to opportunistically access the spectrum not used by primary users. Cognitive radio has many advanced features, such as agilely sensing the existence of primary users and utilizing multiple spectrum bands simultaneously. However, in practice such capabilities are constrained by hardware cost. In this paper, we discuss how to conduct efficient spectrum management in ad hoc cognitive radio networks while taking the hardware constraints (e.g., single radio, partial spectrum sensing and spectrum aggregation limit) into consideration. A hardware-constrained cognitive MAC, HC-MAC, is proposed to conduct efficient spectrum sensing and spectrum access decision. We identify the issue of optimal spectrum sensing decision for a single secondary transmission pair, and formulate it as an optimal stopping problem. A decentralized MAC protocol is then proposed for the ad hoc cognitive radio networks. Simulation results are presented to demonstrate the effectiveness of our proposed protocol.
On the convergence of regret minimization dynamics in concave games

We study a general sub-class of concave games which we call socially concave games. We show that if each player follows any no-external regret minimization procedure then the dynamics will converge in the sense that both the average action vector will converge to a Nash equilibrium and that the utility of each player will converge to her utility in that Nash equilibrium. We show that many natural games are indeed socially concave games. Specifically, we show that linear Cournot competition and linear resource allocation games are socially-concave games, and therefore our convergence result applies to them. In addition, we show that a simple best response dynamics might diverge for linear resource allocation games, and is known to diverge for linear Cournot competition. For the TCP congestion games we show that "near" the equilibrium the games are socially-concave, and using our general methodology we show the convergence of a specific regret minimization dynamics.
Deficiencies of Cardiovascular Risk Prediction Models for Type 1 Diabetes A table elsewhere in this issue shows conventional and Système International (SI) units and conversion factors for many substances.

OBJECTIVE—Cardiovascular risk prediction models are available for the general population (Framingham) and for type 2 diabetes (U.K. Prospective Diabetes Study [UKPDS] Risk Engine) but may not be appropriate in type 1 diabetes, as risk factors including younger age at diabetes onset and presence of diabetes complications are not considered. Therefore, our objective was to examine the accuracy of Framingham and UKPDS models for predicting coronary heart disease (CHD) in a type 1 diabetic cohort. RESEARCH DESIGN AND METHODS—Ten-year follow-up data from the Pittsburgh Epidemiology of Diabetes Complications (EDC) study, a prospective cohort study of 658 subjects with childhood-onset type 1 diabetes diagnosed between 1950 and 1980 first seen in 1986–1988, were analyzed. EDC study data were used to calculate the 10-year probability of CHD (fatal CHD, nonfatal myocardial infarction, or Q-waves) applying to the Framingham and UKPDS equations. RESULTS—Mean age at CHD onset was 39 years. When fatal/nonfatal myocardial infarction and CHD death were modeled, both the UKPDS and Framingham models showed significant lack of calibration (P < 0.0001) but moderate discrimination (0.76 UKPDS, 0.77 Framingham men, and 0.88 Framingham women). Both the UKPDS and Framingham models underestimated probability of events in highest risk deciles. CONCLUSIONS—Currently available CHD models poorly predict events in type 1 diabetes. Future research should focus on determining the risk factors accounting for the lack of fit and developing prediction models specific to this high-risk group.

A STUDY ON TIME MANAGEMENT: CASE OF NORTHEAST NORMAL UNIVERSITY INTERNATIONAL STUDENTS

This study was carried out to investigate the issues of time management by the international students in Northeast Normal University (NENU) Hostel in terms of what activities were done as a schedule of daily life in priority order and how much time was allocated and spend in each prioritized activities as sealed in five Linkert scale basis ranging from never to more than fifteen hours. The research design implied for the study was a phenomenological study where time was taken as a phenomenon. The data was collected via purposive participatory observation. The time duration of the study was one week. The data was analyzed qualitatively but the presentation was made in pyramid diagram to some extent. There were three Research questions led by two research objectives. The result revealed that study, social media, Sleeping/Rest, Eating and Drinking, Travelling, Grooming, Leisure/sports and Working for job-related activities as the top priority activities as the perception of students. The core activities were divided into the time interval series scales including Never, 1-5 Hours, 6-10 Hours, 11-15 Hours and above than 15 Hours. The above table shows that more than 80% of students have the time allocation to study in the range of 6-10 hours and 20%of students enjoy the time less than 6 hours. Maximum students have reported having the time utilization on the use of social media from 1-5 hours’ time allocation.80%of students were founded to use the time to have the talk with teachers and friends in the range of 1-5 hours whereas 20% student consumed the time for communication about the range 6-10 hours. Almost all students were reported to have not regular physical exercise for their health and 20% students have used about 1-5 hours of time for physical exercise. During the campus hours and the days all students have used about 1-5 hours on campus and in the days of off-campus, more than 80% of students were allocating their time in off-campus activities in the range of more than 11 hours. The time allocating for Television Watching for 50% student was zero and other 50% student they were found to watch TV as 1-5 hours range time period. All students were found in the use of social media tools in the time 1-5 hours daily. Maximum students have utilized the 6-10 hours for the daily rest. Article visualizations:
Respiratory sinus arrhythmia during sleep in children with upper airway obstruction

Upper airway obstruction during adulthood is associated with cardiovascular morbidity; cardiovascular consequences of childhood upper airway obstruction are less well established. This study aimed at investigating the effect of childhood upper airway obstruction on respiratory sinus arrhythmia as a measure of cardiac vagal modulation during night‐time sleep. Overnight polysomnography was conducted in 40 healthy children (20 M; age: 7.5 ± 2.6 years; body mass index percentile: 60.7 ± 26.4%) and 40 children with upper airway obstruction (24 M; age: 7.5 ± 2.7 years; body mass index percentile: 65.8 ± 31.9%). We used the phase‐averaging technique to compute respiratory sinus arrhythmia amplitude and phase delay. To study sleep stage effects and the effect of upper airway obstruction, respiratory sinus arrhythmia was measured during all artefact‐free sleep episodes, and after exclusion of respiratory events. A significant increase in respiratory sinus arrhythmia amplitude and phase delay was observed during stage 4 sleep as compared with rapid eye movement sleep in both groups (amplitude: controls = 0.10 ± 0.03 versus 0.07 ± 0.02 s, P < 0.01, respectively, and upper airway obstruction = 0.07 ± 0.03 versus 0.05 ± 0.03 s, P < 0.05, respectively; phase delay: controls = 3.1 ± 0.1 versus 3.0 ± 0.1 rad, P < 0.05, respectively, and upper airway obstruction = 3.13 ± 0.04 versus 3.04 ± 0.08 rad, P < 0.01, respectively). A significant association between respiratory sinus arrhythmia and apnea/hypopnea index was observed during stage 2 sleep in children with upper airway obstruction. Compared with healthy controls, a significant decrease in respiratory sinus arrhythmia amplitude during stage 2 sleep was observed in children with upper airway obstruction (0.09 ± 0.03 versus 0.06 ± 0.03 s, P < 0.05). However, this difference was not apparent when respiratory events were excluded from analysis. Importantly, respiratory sinus arrhythmia showed a strong negative correlation with body mass index. In conclusion, night‐time respiratory sinus arrhythmia in children is sleep stage dependent and normal during quiet sleep in children with relatively mild upper airway obstruction.
Simulation of emotional behaviours for virtual agents with personalities

The last decade has witnessed an explosion of research interest on human emotion modelling for generating intelligent virtual agents. A number of computational emotion models are proposed. Among them, the OCC model is popularly accepted by affective computing researchers for its strong ability in emotion appraisal. Inspired by the OCC model, some other emotion models are also proposed including EM model and FLAME model. However, these models generally do not take personality into consideration. There exist a few emotion models that include consideration for personality, such as ALMA model, WASABI model etc. However, almost all of them use highly stylized stereotypes of personality types, which make emotional responses pale and unrealistic, far from the real world. Additionally, in most of the existing emotion models, virtual agents have very little sense of self-protection. They just passively accept all sorts of stimuli, even when the stimuli are harmful, with no ability nor intention to resist or dodge a harmful event so to protect themselves. Another problem for many existing emotion models is that they only produce a final emotional type without providing any detailed distinctions on Emotion Intensity (EI). For instance, smile, laugh and laugh-out-loud are usually treated equally, all regarded as happiness. Finally, almost all the existed emotion models do not have the ability to present the emotional changes as a dynamic process. The change of emotion should be a progression process, not a final result. Unfortunately this is missing in most of the existing models. This thesis is aiming on establishing an emotion model with consideration on certain personalities. This model should also include a self-protection principle to increase its autonomy and help virtual agent against bad stimuli. Emotions are represented with various intensity levels in this model. In addition, the emotional changes subjected to external stimuli are modelled as a dynamic process that can be clearly represented and monitored through the changing values of PAD (Pleasure, Arousal and Dominance). This thesis implements a basic emotion model including considerations of emotion, mood, instantaneous stimulus, duration stimulus and emotion decay. The well-known PAD (Pleasure, Arousal, and Dominance) model is embedded into the proposed model. All five basic emotional types fear, anger, happiness, disgust and sadness are well supported in the proposed model. This thesis assumes that changes of emotion from a stable status are caused by external stimuli. Once the applied stimulus is removed, emotion starts to decay and tends to go back to its neutral status. Two types of stimuli are considered in this work:
The deep optical imaging of the Extended Groth Strip

We present u',g' R optical images taken with the MMT/Megacam and the Subaru/Suprime telescopes of the Extended Groth Strip survey. The total survey covers an area of about similar to 1 degree(2), including four sub-fields and is optimized for the study of galaxies at z similar to 3. Our methods for photometric calibration in AB magnitudes, the limiting magnitude and the galaxy number count are described. A sample of 1642 photometrically selected candidate Lyman-Break Galaxies (LBGs) to an apparent R(AB) magnitude limit of 25.0 is presented. The average sky surface density of our LBG sample is similar to 1.0 arcmin(-2), slightly higher than the previous finding.
Spontaneous Opening of T-Type Ca2+ Channels Contributes to the Irregular Firing of Dopamine Neurons in Neonatal Rats

During early postnatal development, midbrain dopamine (DA) neurons display anomalous firing patterns and amphetamine response. Spontaneous miniature hyperpolarizations (SMHs) are observed in DA neurons during the same period but not in adults. These hyperpolarizations have been shown to be dependent on the release of Ca2+ from internal stores and the subsequent activation of Ca2+-sensitive K+ channels. However, the triggering mechanism and the functional significance of SMHs remain poorly understood. To address these issues, using brain slices, we recorded spontaneous miniature outward currents (SMOCs) in DA neurons of neonatal rats. Two types of SMOCs were identified based on the peak amplitude. Both types were suppressed by intracellular dialysis of ruthenium red, a ryanodine receptor (RyR) antagonist, yet none of the known Ca2+-releasing messengers were involved. T-type Ca2+ channel blockers (Ni2+ and mibefradil) inhibited large-amplitude SMOCs without affecting the small-amplitude ones. The voltage dependence of SMOCs displayed a peak of approximately -50 mV, consistent with the involvement of low-threshold T-type Ca2+ channels. Blockade of SMOCs with cyclopiazonic acid or ryanodine converted the irregular firing of DA neurons in neonatal rats into an adult-like pacemaker pattern. This effect was reversed by the injection of artificial currents mimicking SMOCs. Finally, amphetamine inhibited SMOCs and transformed the irregular firing pattern into a more regular one. These data demonstrate that Ca2+ influx through T-type Ca2+ channels, followed by Ca2+-induced Ca2+ release via RyRs, contributes to the generation of SMOCs. We propose that SMOCs-SMHs may underlie the anomalous firing and amphetamine response of DA neurons during the postnatal developmental period.
