description: The strategy of constraining the lepton flavor mixing from remnant CP symmetry is investigated in a rather general way. The neutrino mass matrix generally admits four remnant CP transformations which can be derived from the measured lepton mixing matrix in the charged lepton diagonal basis. Conversely, the lepton mixing matrix can be reconstructed from the postulated remnant CP transformations. All mixing angles and CP violating phases can be completely determined by the full set of remnant CP transformations or three of them. When one or two remnant CP transformations are preserved, the resulting lepton mixing matrix would depend on three real parameters or one real parameter respectively in addition to the parameters characterizing the remnant CP, and the concrete form of the mixing matrix is presented. The phenomenological predictions for the mixing parameters are discussed. The conditions leading to vanishing or maximal Dirac CP violation are studied.

description: The effects of a single non-magnetic impurity on superconducting states in the Penson-Kolb-Hubbard model have been analyzed. The investigations have been performed within two steps: (i) the homogeneous system is analysed using the Bogoliubov transformation, whereas (ii) the inhomogeneous system is investigated self-consistent Bogoliubova-de Gennes equations (by exact diagonalization and the kernel polynomial method). We analysed both signs of pair hopping, which correspond to s-wave and $η$-wave superconductivity. Our results show that an enhancement of the local superconducting gap at the impurity-site occurs for both cases. We obtained that Cooper pairs are scattered (at the impurity site) into the states which are from the neighborhoods of the states, which are commensurate ones with the crystal lattice. Additionally, in the $η$-phase there are peaks in the local-energy gap (in momentum space), which are connected with long-range oscillations in the spatial distribution of the energy gap, superconducting order parameter as well as effective pairing potential. Our results can be contrasted with the experiment and predicts how to experimentally differentiate these two different symmetries of superconducting order parameter by scanning tunneling microscopy technique.

description: Phase I finds that board gender diversity is significantly related to women's political and economic empowerment at national level. Phase II finds a significant negative relationship between state ownership and board gender diversity in China (2009 and 2015). In India, a positive relationship between state ownership and board gender diversity in India in 2009 had disappeared by 2015, following the 2013 introduction of a one woman director rule for all listed companies. A positive relationship between female workforce participation and board gender diversity was found in both countries. Phase III examines individual beliefs and attitudes regarding board gender diversity.

description: Depression disproportionately affects LGBTQ (lesbian, gay, bisexual, transgender, or queer) adolescents and young adults. Cognitive behavioral therapy (CBT) is an evidence-based treatment approach; however, there has been limited work to adapt and evaluate CBT with LGBTQ young people. This study examined the feasibility of an intervention called Being Out With Strength (BOWS), which is an 8-session, small-group, CBT-based intervention to reduce depression among LGBTQ young people. We used a descriptive cross-sectional mixed-methods feasibility study design to evaluate the feasibility of BOWS. Survey data were collected from 79 LGBTQ young adults, and interview data were collected from nine mental health professionals. Almost half of the young adults had clinically significant depressive symptoms. All providers indicated depression as a problem facing this population and a need for BOWS. Two-thirds of young people were interested in participating in BOWS. Providers believed that BOWS would be acceptable for LGBTQ-identified individuals, those in late adolescence or early/young adulthood, and those with mild or moderate depression. Youth and providers also made implementation recommendations concerning settings to implement BOWS, times of day for BOWS sessions, number of sessions, group size, and facilitator composition. There is a demand for BOWS, and it is likely acceptable for the target population. Study findings can be used in the future to successfully implement BOWS and evaluate preliminary efficacy.

description: We present explicit solutions of the time-symmetric initial value constraints, expressed in terms of freely specfiable harmonic functions for examples of supergravity theories, which emerge as effective theories of compactified string theory. These results are a prequisite for the study of the time-evolution of topologically non-trivial initial data for supergravity theories, thus generalising the "Geometrodynamics" program of Einstein-Maxwell theory to that of supergravity theories. Specifically, we focus on examples of multiple electric Maxwell and scalar fields, and analyse the initial data problem for the general Einstein-Maxwell-Dilaton theory both with one and two Maxwell fields, and the STU model. The solutions are given in terms of up to eight arbitrary harmonic functions in the STU model. As a by-product, in order compare our results with known static solutions, the metric in isotropic coordinates and all the sources of the non-extremal black holes are expressed entirely in terms of harmonic functions. We also comment on generalizations to time-nonsymmetric initial data and their relation to cosmological solutions of gauged so-called fake supergravities with positive cosmological constant.

description: Objective: This review systematically (1) describes the characteristics of psychosocial interventions for siblings of children with cancer (SCC); (2) assesses the effect of the psychosocial interventions on SCCs' outcomes, and (3) describes SCCs' experiences and perceptions of these interventions. Methods: Seven databases were systematically searched for relevant literature. We included both quantitative and qualitative studies of psychological interventions designed to improve the adjustment of SCCs. Results: Our database searches yielded 19 publications. We found a range of psychosocial interventions being used among SCCs, with group interventions being the most common. The primary outcomes focused on the SCCs' depression, anxiety, and quality of life. Quantitative studies provided insufficient evidence to draw definitive conclusions about the interventions' effects, whereas the qualitative studies indicated that SCCs can derive benefits from these interventions, including an enhanced sense of belonging and bonding, improved family relationships, increased self-awareness and confidence, increased cancer knowledge, and decreased somatic symptoms. Conclusions: Although a growing number of psychosocial interventions have been developed to improve the adjustment of SCCs, research evidence of the effects of these interventions on SCCs' adjustment remains limited. Future research needs to rigorously evaluate the effects of these interventions.

description: Background: Although welfare programs in China provide a safety net for low-income people by directly lifting their incomes, receiving benefits has the potential to affect recipients’ mental health because of the demanding and demeaning means-testing application process required by Chinese policymakers. However, little research has examined the relationship between welfare participation and mental health symptoms—particularly those of depression—among Chinese youth. This study aims to examine the relationship between family participation in the Dibao income-assistance program in China and symptoms of depression among youth. Methods: This study used a youth sample (n = 4192) of nationally representative data from the China Family Panel Studies (CFPS) survey. Multiple imputation was used to deal with missing data. The imputed data were analyzed using aggregated robust multiple regression. The Center for Epidemiological Studies Depression (CES-D-20) scale was used to measure depression symptoms. In addition, a variety of subgroup analyses were conducted to explore whether the relationship between Dibao participation and symptoms of depression differs significantly by the sociodemographic characteristics. Results: Youth whose families received Dibao assistance had significantly greater risk for symptoms of depression when compared with peers who did not receive assistance. Results also showed that young women—and especially young mothers—whose families participated in the Dibao program in rural areas were at significantly higher risk compared with others. Conclusion and Discussion: The relationship between welfare participation and symptoms of depression varies significantly by the characteristics of youths and their families. As a marker for collective disadvantage and adversity, welfare participation warrants research to study program processes and to distinguish pathways—possibly differentiated by gender—that may elevate risk for depression among Dibao program recipients.

Inverse Magnetic Catalysis in the three-flavor NJL model with axial-vector interaction

description: In this paper we explore the chiral phase transition in QCD within the three-flavor Nambu-Jona-Lasinio (NJL) model with a negative coupling constant in the isoscalar axial-vector channel, which is associated with a polarized instanton--anti-instanton molecule background. The QCD phase diagram described in this scenario shows a new first order phase transition around the transition temperature $T_c$ toward a phase without chiral condensates, but with nontrivial dynamic chiral chemical potentials for the light quarks, spontaneously giving rise to local $\mathcal {CP}$ violation and local chirality imbalance. The corresponding critical temperature $T_{5c}$ for this phase transition decreases with the magnetic field and it gives a natural explanation to the inverse magnetic catalysis effect for light quarks when incorporating a reasonable value of the coupling constant in the isoscalar axial-vector channel. Furthermore, when the isoscalar axial-vector interaction is dominant in light quark sector and suppressed in strange quark sector, it is found that there is no inverse magnetic catalysis for strange quark condensate, which agrees with lattice results.

description: Using historical capital market data for Germany (1950-2022) we analyze and compare (individual) defined contribution (IDC-) and collective defined contribution (CDC) pension plans. To this end we define simple asset liability management rules that govern a CDC pension plan and compare these to IDC-plans with the same asset allovation. Our main result is, that the CDC pension plans allow for a significant improvement of the risk return profile compared to individual pension plans. Hereby we consider different risk measures. This empirical study affirms the theoretical results based on stochastic CDC-models.

description: As China’s economy is rapidly changing from a planned to a capitalist economy, many families find themselves financially struggling. In some cases, conflicting values and attitudes may contribute to mental health challenges such as depression that would lead to further feelings of helplessness and immobilization. Using a random sample of 1006 low-income households from Pudong District of Shanghai, China, this study aims to examine the relationships between household assets, beliefs about government as the primary way to improve economic circumstances and self-reported depressive symptoms. In addition, this study investigates the mediation effects of beliefs that government is the best change agent for improved life circumstances on the relationship between household assets and depression. We found those who indicated that government was the main means for attaining a better life had significantly higher depression levels whereas higher numbers of household assets were associated with lower depression levels. We also found that viewing government as the most important change agent only partially mediated the relationship between household assets and depression (p <.001). Findings from this study support anti-poverty policies and social work related practice initiatives aimed at assisting low income families in China, in particular the need to address psychological as well as economic needs.

description: Excerpts from the report Introduction: The Office of Civil Defense is assigned the responsibility for development of civil defense preparedness measures by Executive Order 10952. One important concern of civil defense is the availability of food supplies and the number of days during which a given population can be fed from stocks on hand in emergency situations. With an abundance of food on a national basis, the problem centers on the geographic distribution of the available supply in relation to population. Executive Order 10998 directs the U. S. Department of Agriculture to assess periodically food resources available from all sources in order to estimate availability under an emergency situation. Executive Order 10958 gives the Department of Agriculture responsibility for any food stockpiling. This report was prepared to meet the needs of the Office of Civil Defense and the Department of Agriculture and others concerned with civil defense. The data by counties. States, and regions are not precise. They are intended to show where available food supplies might be large or small in a national emergency. Even if different assumptions were made regarding the ability to transport food and minimum civilian food requirements in an emergency, the picture would remain relatively the same. Local food surpluses and deficits, in this case, might be greater or less than those shown here.

description: Background: Latinos in the USA have reported more frequent discriminatory treatment in healthcare settings when compared to their White counterparts. In particular, foreign-born Latinos report discrimination more than Latinos born in the USA. Such patient-reported racial/ethnic discrimination appears to contribute to specific health consequences, including treatment seeking delays, interruptions in care, and medical mistrust. Immigrant Latino adolescents in the USA experience a variety of health disparities, yet little is known about their views of the healthcare experience, their perceptions of discriminatory treatment, or ways in which they would like their relationships with healthcare providers to be different. Methods: This work, based in a larger interdisciplinary social work-led initiative, used photovoice with two groups of immigrant Latino adolescents to explore the topic “what I wish the doctor knew about my life.” The findings were used to engage healthcare stakeholders as part of a pilot intervention aimed at decreasing provider bias toward immigrant Latino youth. Results/Discussion: Findings illuminated ways that the immigrant experience affects the lives and health of Latino adolescents in North Carolina. To improve their health, it is critical to understand, from their perspectives, the ways their lives can be complicated by experiences of migration, stereotypes, and cross-cultural communication challenges and how their interactions with authority figures in one sector, such as education, influence interactions in health care. Understanding the healthcare barriers faced by immigrant Latino youth is critical to any effort to improve the system of care for immigrant Latino populations.

description: We study a noncommutative theory of gravity in the framework of torsional spacetime. This theory is based on a Lagrangian obtained by applying the technique of dimensional reduction of noncommutative gauge theory and that the yielded diffeomorphism invariant field theory can be made equivalent to a teleparallel formulation of gravity. Field equations are derived in the framework of teleparallel gravity through Weitzenbock geometry. We solve these field equations by considering a mass that is distributed spherically symmetrically in a stationary static spacetime in order to obtain a noncommutative line element.This new line element interestingly reaffirms the coherent state theory for a noncommutative Schwarzschild black hole. For the first time, we derive the Newtonian gravitational force equation in the commutative relativity framework, and this result could provide the possibility to investigate examples in various topics in quantum and ordinary theories of gravity.

description: Bullying threatens the mental and educational well-being of students. All states have enacted antibullying laws. This study surveyed 634 educators about the implementation of the North Carolina School Violence Prevention Act, which enumerated social classes protected from bullying: race, national origin, gender, socioeconomic status, sexual orientation, gender identity, appearance, and disability. Results showed that local antibullying policies most often included race as a protected class and least often included sexual orientation and gender identity. More educators had been trained on bullying based on race than any other social class. Students were more often informed that bullying based on race was prohibited and were least often informed about prohibitions regarding sexual orientation and gender identity. Reporting, investigating, and remediating bullying was highest for racial bullying, followed by disability bullying, and was lowest for bullying based on sexual orientation and gender identity.
Self-similarity relations for cooling superfluid neutron stars

description: We consider models of cooling neutron stars with nucleon cores which possess moderately strong triplet-state superfluidity of neutrons. When the internal temperature drops below the maximum of the critical temperature over the core, $T_{\rm C}$, this superfluidity sets in. It produces a neutrino outburst due to Cooper pairing of neutrons which greatly accelerates the cooling. We show that the cooling of the star with internal temperature $T$ within $0.6\,T_{\rm C} \lesssim T \leq T_{\rm C}$ is described by analytic self-similar relations. A measurement of the effective surface temperature of the star and its decline, supplemented by assumptions on star's mass, radius and composition of heat-blanketing envelope, allows one to construct a family of cooling models parametrized by the value of $T_{\rm C}$. Each model reconstructs cooling history of the star including its neutrino emission level before neutron superfluidity onset and the intensity of Cooper pairing neutrinos. The results are applied to interpret the observations of the neutron star in the Cassiopeia A supernova remnant.

description: Using a novel electronic implementation of a well-known time-delayed system, the Mackey-Glass (MG) system, we investigate the organization of the trajectories in the phase space, and classify the coexisting solutions, both, in observations and in model simulations. The numerical simultations are performed using a discrete-time equation that approximates the exact solutions of the MG model and in particular, models the delay line in the electronic circuit. In wide parameter regions, different periodic or aperiodic solutions, but with similar waveforms exhibiting the alternation of peaks of different amplitudes, coexist. A symbolic algorithm is proposed to classify those solutions. The system's phase-space was explored by varying the parameter values of two families of initial functions.

Publisher: name: SAGE Publications Inc.
Year: 2018

description: Bullying is a significant problem in U.S. schools. Policies have been developed to reduce bullying, yet policy implementation by educators is an essential yet difficult and complex process. Few studies have investigated factors that act as barriers to or facilitators of bullying policy implementation and teacher protection of students. This study examined the influence of school context on educators’ capacity to implement a statewide bullying law and protect students from bullying following the enactment of the policy. Data were collected from 505 educators in 324 schools. School administrators tended to rate fidelity of policy implementation and teacher protection of students higher than teachers, education support professionals, and student service professionals. Policy implementation fidelity scores were higher in high schools than elementary schools. School size and the prevalence of student suspensions were inversely related to implementation fidelity. Higher levels of teacher protection were reported in elementary schools.

description: In this paper we introduce a LTB-Bianchi I (plane symmetric) model of Universe. We study and solve Einstein field equations. We investigate the effects of such model of Universe in particular these results are important in understanding the effect of the combined presence of an inhomogeneous and anisotropic Universe. The observational magnitude-redshift data deviated from UNION 2 catalog has been analyzed in the framework of this LTB-anisotropic Universe and the fit has been achieved without the inclusion of any dark energy.

description: We consider a six dimensional (1,0) hypermultiplet model coupled to an external field of vector/tensor system and study the structure of the low-energy effective action of this model. Manifestly a (1,0) supersymmetric procedure of computing the effective action is developed in the framework of the superfield proper-time technique. The leading low-energy contribution to the effective action is calculated.

description: This work introduces a methodology for determination of energy balance for solar water heater (SWH). Solar legislation in Israel requires installation of solar water heaters in new buildings up to 9 floors from roof. The legislation from year 1980 is based on technology of late 70's. This publication compares old types of installation (steel pipe) with the current common practice (2017) of installation of solar water heaters in Israel. The results are energy losses for circulation pipes, hot water supply pipes and storage tank. The publication introduces also the Israeli system of determination of size of solar water heater and describes the procedure to determine amount of energy gained by the heater every month. It analyzes thermosyphonic systems, but may be helpful to analyze also forced circulation systems. The balance is for demand scenario as determined using national statistics (unique for Israel). The balance shows that in most months of the year SWH supplies more hot water than required for sanitary use. Most of the hot water from solar energy is used for showers while the rest may be used for other applications like washing machines and dishwashers. The balance shows that the main losses of energy are for storage tank envelope, while hot water supply pipes are minor energy users. This work may be helpful for techno-economic evaluation of water heating options and determination of the optimum solutions. It also contains large volume of useful data and information and can serve as solar water heating manual or basic material for solar energy study.

description: We study the space of local operators in the sinh-Gordon model in the framework of the bootstrap form factor approach. Our final goal is to identify the operators obtained by solving bootstrap equations with those defined in terms of the Lagrangian field. Here we try to identify operators at some very particular points, where the phenomenon of operator resonance takes place. The operator resonance phenomenon being perturbative, nevertheless, results in exact identities between some local operators. By applying an algebraic approach developed earlier for form factors we derive an infinite set of identities between particular descendant and exponential operators in the sinh-Gordon theory, which generalize the quantum equation of motion. We identify the corresponding descendant operators by comparing them with the result of perturbation theory.

description: We discuss the universality and self-similarity of void density profiles, for voids in realistic mock luminous red galaxy (LRG) catalogues from the Jubilee simulation, as well as in void catalogues constructed from the SDSS LRG and Main Galaxy samples. Voids are identified using a modified version of the ZOBOV watershed transform algorithm, with additional selection cuts. We find that voids in simulation are self-similar, meaning that their average rescaled profile does not depend on the void size, or -- within the range of the simulated catalogue -- on the redshift. Comparison of the profiles obtained from simulated and real voids shows an excellent match. The profiles of real voids also show a universal behaviour over a wide range of galaxy luminosities, number densities and redshifts. This points to a fundamental property of the voids found by the watershed algorithm, which can be exploited in future studies of voids.

description: Negative attitudes and discrimination against Latinos exist in the dominant U.S. culture and in healthcare systems, contributing to ongoing health disparities. This article provides findings of a pilot test of Yo Veo Salud (I See Health), an intervention designed to positively modify attitudes toward Latinos among medical trainees. The research question was: Compared to the comparison group, did the intervention group show lower levels of implicit bias against Latinos versus Whites, and higher levels of ethnocultural empathy, healthcare empathy, and patient-centeredness? We used a sequential cohort, post-test design to evaluate Yo Veo Salud with a sample of 69 medical trainees. The intervention setting was an academic medical institution in a Southeastern U.S. state with a fast-growing Latino population. The intervention was delivered, and data were collected online, between July and December of 2014. Participants in the intervention group showed greater ethnocultural empathy, healthcare empathy, and patient-centeredness, compared to the comparison group. The implicit measure assessed four attitudinal dimensions (pleasantness, responsibility, compliance, and safety). Comparisons between our intervention and comparison groups did not find any average differences in implicit anti-Latino bias between the groups. However, in a subset analysis of White participants, White participants in the intervention group demonstrated a significantly decreased level of implicit bias in terms of pleasantness. A dose response was also founded indicating that participants involved in more parts of the intervention showed more change on all measures. Our findings, while modest in size, provide proof of concept for Yo Veo Salud as a means for increasing ethno-cultural and physician empathy, and patient-centeredness among medical residents and decreasing implicit provider bias toward Latinos.

description: Welfare programs play important roles in the lives of vulnerable populations. However, since their inception, welfare programs have been accompanied by contentious debate about their impact on the wellbeing of participants and, hence, about their collective value as a strategy for alleviating poverty. This study uses welfare participation as a marker of lower socioeconomic status to identify and synthesize the relationship between welfare participation and depression among youth. A systematic review was undertaken based on literature published between 1997 and 2017 through a search of 9 electronic databases, 15 reports met criteria for study inclusion. Four descriptive studies reported mixed findings. Of the 11 comparison studies, 10 studies showed consistent findings that participation in welfare programs was associated with a higher vulnerability for depression. Discussion includes the effects of stigma related to welfare and mental health treatment, and the implications for policy makers, social workers, and future research.

description: The 2014 Research Excellence Framework (REF2014) formally introduced Research Impact as one of the measures used to assess the quality of research produced by UK Higher Education Institutions (HEIs). Whilst impact assessment represented a significant shift in the assessment of research (Comunian et al 2014) by moving beyond conventional forms of peer-review and professional standing, it was also forged from long-standing academic traditions. Impact assessment was designed through interactions with the academic community (Wroblewska, 2021) and rooted in established academic commitments to epistemic responsibility (Chubb & Reed, 2017). Rather than seeking to significantly change research or researcher behaviour, impact can therefore be viewed as a change to discourses, creating additional ways to value research and opportunities to renegotiate academic identities.
This Case Study focusses on the role of the underpinning research environment in supporting the development of research impact. Drawing on data from across the 2014 and 2021 REF periods, it provides an in-depth depiction of how one School of Art and Design responded to the introduction of impact assessment. Document analysis, quantitative analysis and semi-structured interviews with research active staff were used to explore the research environment from multiple perspectives and identify strategies to help staff effectively demonstrate the impact of Art and Design (A&D) research.
The Case reveals a School and University with a maturing research environment that has made substantial strides in incorporating impact into its research operations. It highlights that, for A&D researchers who are already engaged in collaborative, interdisciplinary and/or co-participatory research, the concept of impact is well understood and accepted. However, context-specific approaches to developing research environments are required to bridge the gap between institutional strategies and researcher’s needs to ensure that research remains accessible pathway for Emerging Career Researchers and, in doing so, fosters a sustainable, high-performing research environment capable of supporting impactful research.
