Relationships among cyber dating abuse, binge drinking, and emotion dysregulation in college students

Aims: Cyber dating abuse (CDA) is an emerging problem for college students, with prevalence ranging from 20% to 74%. Students experiencing CDA are at increased risk of experiencing poor emotional control (i.e., emotion dysregulation). Additionally, more than half of students report drinking alcohol in the past month with two-thirds binge drinking. Alcohol use is shown to negatively affect emotional responses. Thus, this study examined the relationships among CDA, binge drinking, and emotion dysregulation in college students. Methods: A longitudinal, descriptive correlational design was used for this secondary analysis of data from a parent study of 2,092 students from 27 college health or counseling centers in Pennsylvania and West Virginia. Students completed CDA, binge drinking, and emotion dysregulation surveys at baseline and 4- and 12-month follow-up. This sample consisted of 740 students who completed all survey items. A clustered negative binomial model with a generalized estimating equation was used to test the effects of baseline CDA on binge drinking at 4- and 12-month follow-up. A linear mixed model was used to test the association between baseline CDA on emotion dysregulation at 12-month follow-up, and binge drinking at 4- and 12-month follow-up on emotion dysregulation at 12-month follow-up. All analyses accounted for clustering of students nested within schools. Results: Results showed CDA significantly predicted binge drinking at 4- and 12- month-follow- up in the unadjusted models but not in the adjusted models. However, in the adjusted models, baseline binge drinking significantly predicted binge drinking at 4- and 12-month follow-up. There was no significant association between CDA and emotion dysregulation at 12-month follow-up and no significant association between binge drinking at 4- and 12-month follow-up and emotion dysregulation at 12-month follow-up. Conclusion: Although CDA did not significantly predict binge drinking at 4- and 12-month follow-up, this finding may be attributed to the highly significant covariate of baseline binge drinking. Previous research found that baseline binge drinking is a strong predictor of future drinking in students. This study is impactful for guiding future research in developing and examining prevention and intervention strategies for students who experience a combination of CDA, binge drinking, and emotion dysregulation

Eigenvalue Algorithm for Hausdorff Dimension on Complex Kleinian Groups

In this manuscript, we present computational results approximating the Hausdorff dimension for the limit sets of complex Kleinian groups. We apply McMullen\u27s eigenvalue algorithm \cite{mcmullen} in symmetric and non-symmetric examples of complex Kleinian groups, arising in both real and complex hyperbolic space. Numerical results are compared with asymptotic estimates in each case. Python code used to obtain all results and figures can be found at \url{https://github.com/WXML-HausDim/WXML-project}, all of which took only minutes to run on a personal computer

Parametrization and distillability of three-qubit entanglement

There is an ongoing effort to quantify entanglement of quantum pure states for systems with more than two subsystems. We consider three approaches to this problem for three-qubit states: choosing a basis which puts the state into a standard form, enumerating ``local invariants,'' and using operational quantities such as the number of maximally entangled states which can be distilled. In this paper we evaluate a particular standard form, the {\it Schmidt form}, which is a generalization of the Schmidt decomposition for bipartite pure states. We show how the coefficients in this case can be parametrized in terms of five physically meaningful local invariants; we use this form to prove the efficacy of a particular distillation technique for GHZ triplets; and we relate the yield of GHZs to classes of states with unusual entanglement properties, showing that these states represent extremes of distillability as functions of two local invariants.Comment: 17 pages RevTeX 3.0 including 2 figures (encapsulated Postscript) Final version, to appear in Physics Letters

The cholesterol transporter ABCG1 links cholesterol homeostasis and tumour immunity

ATP-binding cassette transporter G1 (ABCG1) promotes cholesterol efflux from cells and regulates intracellular cholesterol homeostasis. Here we demonstrate a role of ABCG1 as a mediator of tumour immunity. Abcg1-/- mice have dramatically suppressed subcutaneous MB49-bladder carcinoma and B16-melanoma growth and prolonged survival. We show that reduced tumour growth in Abcg1-/- mice is myeloid cell intrinsic and is associated with a phenotypic shift of the macrophages from a tumour-promoting M2 to a tumour-fighting M1 within the tumour. Abcg1-/- macrophages exhibit an intrinsic bias towards M1 polarization with increased NF-κB activation and direct cytotoxicity for tumour cells in vitro. Overall, our study demonstrates that the absence of ABCG1 inhibits tumour growth through modulation of macrophage function within the tumour, and illustrates a link between cholesterol homeostasis and cancer. © 2015 Macmillan Publishers Limited.

Socio-demographic predictors associated with capacity to engage in health care

Patient engagement is essential to improve outcomes and reduce healthcare costs. This study aimed to examine the socio-demographic factors associated with one’s capacity to engage in their health care. An observational, cross-sectional study was performed including patients from five medical/surgical units of four health systems. Patients’ engagement capacity was assessed using the person engagement index (PEI) instrument which contains four subscales: engagement in health care, technology use in health care, proactive approach to health care, and psychosocial support for health care. Separate general linear models were applied for the PEI total score and each of the four subscale scores. Our results show that younger age was associated with greater technology use in health care. Individuals with higher educational levels have a greater overall engagement and the use of technology in their health care. A higher level of psychosocial support was found among blacks and those being employed. No difference in the proactive approach was found by one’s socio-demographic factors. This study illustrated that an individual’s age, race, educational level, and employment status were associated with the capacity to engage in different aspects of health care activities. Providers need to assess one’s readiness for engagement to deliver customized interventions based on their needs and capacity to engage.

Bounds on relative entropy of entanglement for multi-party systems

We present upper and lower bounds to the relative entropy of entanglement of multi-party systems in terms of the bi-partite entanglements of formation and distillation and entropies of various subsystems. We point out implications of our results to the local reversible convertibility of multi-party pure states and discuss their physical basis in terms of deleting of information.Comment: 4 pages, no figure

Vnímání, kauzalita a pozornost Roger Bacon a Petr Olivi

[Sensation, Causality, and Attention: Roger Bacon and Peter Olivi] This paper investigates what conditions are to be met for sensory perception to occur. It introduces two diff erent theories of perception that were held by two medieval Franciscan thinkers — namely, Roger Bacon (1214/1220–1292) and Peter Olivi (ca. 1248–1298). Bacon analyses especially the causal relation between the object and the sensory organ in his doctrine of the multiplication of species. In his view, a necessary condition of perception is the reception of the species in a fully disposed sensory organ. On the contrary, Olivi stresses the active role of the sensory power. A necessary condition of sensation is the aspectus — i.e. the focus of our power’s attention on the object. Furthermore, the paper investigates whether and how each of the two thinkers can deal with the arguments proposed by his opponent — namely whether Bacon’s theory is able to explain attention and what the causal role of the object in Olivi’s theory is

Tripartite entanglement and quantum relative entropy

We establish relations between tripartite pure state entanglement and additivity properties of the bipartite relative entropy of entanglement. Our results pertain to the asymptotic limit of local manipulations on a large number of copies of the state. We show that additivity of the relative entropy would imply that there are at least two inequivalent types of asymptotic tripartite entanglement. The methods used include the application of some useful lemmas that enable us to analytically calculate the relative entropy for some classes of bipartite states.Comment: 7 pages, revtex, no figures. v2: discussion about recent results, 2 refs. added.

Three-qubit pure-state canonical forms

In this paper we analyze the canonical forms into which any pure three-qubit state can be cast. The minimal forms, i.e. the ones with the minimal number of product states built from local bases, are also presented and lead to a complete classification of pure three-qubit states. This classification is related to the values of the polynomial invariants under local unitary transformations by a one-to-one correspondence.Comment: REVTEX, 9 pages, 1 figur

The effect of substituents on the syn-anti conformer ratio in naphthyl-based imidazolinium salts and their corresponding N-heterocyclic carbenes

Eight new N-heterocyclic carbenes (NHCs) featuring substituted naphthyl side chains were synthesized. These molecules are present in solution as a stable mixture of antiand synconformers. Through careful tuning of the substituents on position 2 and 2,7 of the naphthyl moieties, it was possible to synthesize molecules that display a strong preference for the anticonformation (up to 95:5). This will greatly facilitate their optimized use as single isomeric ligands in metal-catalysis and as organocatalysts
