We analyze the performance of the recently proposed screened exchange constant functional (SX) (Phys. Rev. X \textbf{2016}, 10, 642) on the GW100 test set, and we discuss results obtained at different levels of self-consistency. The SX functional is a generalization of dielectric dependent hybrid functionals to finite systems, it is non-empirical and depends on the average screening of the exchange interaction. We compare results for ionization potentials obtained with SX to those of CCSD(T) calculations and experiments and we find excellent agreement, on par with recent state of the art methods based on many body perturbation theory...

BACKGROUND: Positive parenting practices and environmental supports have been linked to physical activity (PA) levels in youth, yet factors associated with positive parenting styles have been understudied in African American adolescents. PURPOSE: This study expands on previous literature by examining associations between motivation, parenting factors associated with Self-Determination Theory's psychological needs (competence, autonomy, and relatedness) including authoritative parenting, autonomy support and emotional and tangible support, and adolescent moderate-to-vigorous PA (MVPA) and light PA (LPA)...

BACKGROUND: Although motivation of health workers in low- and middle-income countries (LMICs) has become a topic of increasing interest by policy makers and researchers in recent years, many aspects are not well understood to date. This is partly due to a lack of appropriate measurement instruments. This article presents evidence on the construct validity of a psychometric scale developed to measure motivation composition, i.e., the extent to which motivation of different origin within and outside of a person contributes to their overall work motivation...

Burkhard Gniewosz, Helen M G Watt
This study examines whether and how student-perceived parents' and teachers' overestimation of students' own perceived mathematical ability can explain trajectories for adolescents' mathematical task values (intrinsic and utility) controlling for measured achievement, following expectancy-value and self-determination theories. Longitudinal data come from a 3-cohort (mean ages 13.25, 12.36, and 14.41 years; Grades 7-10), 4-wave data set of 1,271 Australian secondary school students. Longitudinal structural equation models revealed positive effects of student-perceived overestimation of math ability by parents and teachers on students' intrinsic and utility math task values development...

Conditions that cause cognitive impairment and behavioural and personality changes, such as Alzheimer's disease (AD) and related dementia, have global impact across cultures. However, the experience of dementia care can vary between individuals, families, formal caregivers, and social groups from various cultures. Self-reported measures, caregiving stress models, and conceptual theories have been developed to address the physical, financial, psychological, and social factors associated with the experience of dementia care...

Ruiping Wen, Hui Duan
In this paper, a parallel multisplitting iterative method with the self-adaptive weighting matrices is presented for the linear system of equations when the coefficient matrix is an H-matrix. The zero pattern in weighting matrices is determined in advance, while the non-zero entries of weighting matrices are determined by finding the optimal solution in a hyperplane of α points generated by the parallel multisplitting iterations. Especially, the nonnegative restriction of weighting matrices is released. The convergence theory is established for the parallel multisplitting method with self-adaptive weightings...

Rui Zhang, Kenneth S Schweizer
We formulate a microscopic, force-level statistical mechanical theory for the activated diffusion of dilute penetrants in dense liquids, colloidal suspensions, and glasses. The approach explicitly and self-consistently accounts for coupling between penetrant hopping and matrix dynamic displacements that actively facilitate the hopping event. The key new ideas involve two mechanistically (at a stochastic trajectory level) coupled dynamic free energy functions for the matrix and spherical penetrant particles...

The few previous studies investigating regulation of gender in trans-specific healthcare are mainly based on text material and interviews with care-providers or consist solely of theoretical analyses. There is a lack of studies analysing how the regulation of gender is expressed in the care-seeker's own experiences, especially in a Nordic context. The aim of this study is to analyse narratives of individuals with trans experiences (sometimes called transgender people) to examine how gender performances can be regulated in trans-specific care in Sweden...

School adjustment determines long-term adjustment in society. Yet, immigrant youth do better in some countries than in others. Drawing on acculturation research (Berry, 1997; Ward, 2001) and self-determination theory (Ryan and Deci, 2000), we investigated indirect effects of adolescent immigrants' acculturation orientations on school adjustment (school-related attitudes, truancy, and mathematics achievement) through school belonging. Analyses were based on data from the Programme for International Student Assessment from six European countries, which were combined into three clusters based on their migrant integration and multicultural policies: Those with the most supportive policies (Belgium and Finland), those with moderately supportive policies (Italy and Portugal), and those with the most unsupportive policies (Denmark and Slovenia)...

Stefan Landmann, Nicolas Preuss, Ulrich Behn
We consider self-tolerance and its failure -autoimmunity- in a minimal mathematical model of the idiotypic network. A node in the network represents a clone of B-lymphocytes and its antibodies of the same idiotype which is encoded by a bitstring. The links between nodes represent possible interactions between clones of almost complementary idiotype. A clone survives only if the number of populated neighbored nodes is neither too small nor too large. The dynamics is driven by the influx of lymphocytes with randomly generated idiotype from the bone marrow...

Attachment theory has been proposed as one explanation for the relationship between childhood maltreatment and problematic mental and physical health outcomes in adulthood. This study seeks to determine whether: (1) childhood physical abuse and neglect lead to different attachment styles in adulthood, (2) adult attachment styles predict subsequent mental and physical health outcomes, and (3) adult attachment styles mediate the relationship between childhood physical abuse and neglect and mental and physical health outcomes...

BACKGROUND: Communication about physical activity (PA) frames PA and influences what it means to people, including the role it plays in their lives. To the extent that PA messages can be designed to reflect outcomes that are relevant to what people most value experiencing and achieving in their daily lives, the more compelling and effective they will be. Aligned with self-determination theory, this study investigated proximal goals and values that are salient in everyday life and how they could be leveraged through new messaging to better support PA participation among women...

In medical education, students are increasingly regarded as active seekers of feedback rather than passive recipients. Previous research showed that in the intentions of students to seek feedback, a learning and performance goal can be distinguished. In this study, we investigated the intentions (defined as level and orientation of motivation) of different performing students (low, average, and high performing students) to seek feedback in the clinical workplace using Self-Determination Theory. We conducted a quantitative study with students in their clinical clerkships and grouped them based on their performance...

Metacognitive verbs (MCVs) such as believe, know and think allow a speaker to describe the thoughts, feelings and perspectives of the self and others. As such, these words reflect the speaker's awareness of differing mental events and activities, or Theory of Mind (ToM). This study investigated the use of MCVs in adolescents with typical language development in relation to the production of complex sentences. It was of interest to determine the frequency with which adolescents used MCVs and to explore the links between MCVs and different types of subordinate clauses...

BACKGROUND: Family caregivers of people living with dementia can have both positive and negative experiences of caregiving. Despite this, existing outcome measures predominately focus on negative aspects of caregiving such as burden and depression. This review aimed to evaluate the development and psychometric properties of existing positive psychology measures for family caregivers of people living with dementia to determine their potential utility in research and practice. METHOD: A systematic review of positive psychology outcome measures for family caregivers of people with dementia was conducted...

INTRODUCTION: Self-Determination Theory explores the process through which a person acquires motivation to initiate new behaviours related to health and to maintain them over time. This study aimed to determine the overall fit of Self-Determination Theory Model for Health Behavior to the data obtained from a sample of smokers hospitalized with acute coronary syndrome, and to identify the predictors of smoking status six months after clinical discharge. MATERIAL AND METHODS: The sample included 110 participants, regular smokers, hospitalized due to acute coronary syndrome...

BACKGROUND: Self-determination theory (SDT) provides a model to improve pharmacy students' well-being or functioning in their study context. According to SDT, students need a context that satisfies their needs for autonomy, relatedness and competence in order to function optimally. Contextual factors that could have an impact on a student's functioning are lecturers, family, peers and workload. OBJECTIVES: To investigate whether there is a difference between the contributions family, lecturers, peers and workload make towards the satisfaction of pharmacy students' basic psychological needs within a university context...

BACKGROUND: Unhealthy eating and physical activity behaviours are common among nurses but little is known about determinants of eating and physical activity behaviour in this population. The present study used a theoretical framework which summarises the many possible determinants of different health behaviours (the Theoretical Domains Framework; TDF) to systematically explore the most salient determinants of unhealthy eating and physical activity behaviour in hospital-based nurses. METHODS: Semi-structured qualitative interviews based on the TDF were conducted with nurses (n = 16) to explore factors that behavioural theories suggest may influence nurses' eating and physical activity behaviour...
