Sexual Diversity Bullying and Cyberbullying Questionnaires: An Inclusive Approach to Measure Sexuality-Based Bullying.

LGBTQ+ bullying is a specific type of stigma-based bullying with a high prevalence among LGBTQ+ people. However, instruments to assess this phenomenon are scarce and focus on homophobic aggressions, and the motivations therefor, mainly in relation to gay and lesbian youths. In this study, we introduce and validate an instrument to assess LGBTQ+ bullying.

Outlining Individual and Contextual Factors Related to LGBTQ+ Bullying: A Systematic Review of Two Decades of Research.

Scientific interest in lesbian, gay, bisexual, transgender, queer and any other sexual orientation, gender identity and/or expression (LGBTQ+) bullying in educational settings has grown exponentially in recent years. However, the varied ways of measuring its occurrence and associated factors have made it difficult to achieve a holistic understanding of this problem. Therefore, this systematic review aimed to provide an updated overview of individual and contextual factors related to LGBTQ+ bullying over the past two decades, based on the measurement approach to this phenomenon.

Traditional and cyber dating violence among adolescents: Profiles, prevalence, and short-term associations with peer violence.

There is a paucity of studies on dating violence profiles that incorporate the forms of cyber and sexual dating violence. Moreover, the results on the predictive role of peer violence on dating violence are inconsistent. Our aim was to identify dating violence profiles and to study the predictive value of peer violence profiles on dating violence profiles using a short-term longitudinal design.

Sexting Among Adolescents: The Emotional Impact and Influence of the Need for Popularity.

Sexting refers to the exchange of sexual content material technological devices. The definitions of this phenomenon vary greatly, mainly, depending on the types of sexting: primary and secondary. Besides the above, there is no common perspective on whether sexting is a risk behavior that entails some type of impact by itself or not and, in such a case, whether this impact varies according to gender.

Body Image and Sexual Dissatisfaction: Differences Among Heterosexual, Bisexual, and Lesbian Women.

Gender-based differences in body image dissatisfaction are not conclusive. Women's body experiences and their impact on sexual satisfaction may advance knowledge on how heterosexual, bisexual, and lesbian women internalize heterosexist values. In this study, we quantitatively examined the degree of body image and sexual dissatisfaction experienced by heterosexual, bisexual, and lesbian women, to determine whether body dissatisfaction can predict sexual dissatisfaction.

Development and Validation of an Instrument to Assess the Impact of Cyberbullying: The Cybervictimization Emotional Impact Scale.

Cyberbullying is a phenomenon with important adverse consequences on victims. The emotional impact of this phenomenon has been well established. However, there is to date no instrument with good psychometric properties tested to assess such impact.

Homophobic Bullying and Cyberbullying: Study of a Silenced Problem.

Bullying and cyberbullying have been studied extensively. In lesbian, gay, bisexual, and questioning (LGBQ) students, these phenomena seem to be overrepresented so that, although they share some common elements, homophobic bullying and cyberbullying could be considered as specific phenomena. This study analyzed homophobic bullying and cyberbullying, with the participation of 533 Spanish secondary school students aged from 12 to 20 (M = 14.

Canthotomy and cantholysis prior to ultrasound circular cyclocoagulation (UC3 Eye Tech Care) in refractory glaucoma.

Case Report: The case is presented on a patient with primary open-angle glaucoma treated with the novel ultrasound circular cyclocoagulation technique (UC3 [EyeTechCare, Rillieux La Pape, France]), who had previously undergone glaucoma surgery. Due to having extreme palpebral rigidity, worsened by the pre-operative local anesthesia injections, a canthotomy and cantholysis were needed to correctly position of the UC3 probe cone. Clinical outcome as regards the IOP and the surgical wound was very satisfactory.

Search for patterns by combining cosmic-ray energy and arrival directions at the Pierre Auger Observatory.

Energy-dependent patterns in the arrival directions of cosmic rays are searched for using data of the Pierre Auger Observatory. We investigate local regions around the highest-energy cosmic rays with [Formula: see text] eV by analyzing cosmic rays with energies above [Formula: see text] eV arriving within an angular separation of approximately 15[Formula: see text]. We characterize the energy distributions inside these regions by two independent methods, one searching for angular dependence of energy-energy correlations and one searching for collimation of energy along the local system of principal axes of the energy distribution.

Bullying and cyberbullying: overlapping and predictive value of the co-occurrence.

Several studies show certain co-occurrence of the traditional bullying and the cyberbullying. However, the results about relation and homogeneity among the roles of each of them are not unanimous. The present study intends to advance in the knowledge about the above-mentioned co-occurrence by exploring the dimensions of victimization and traditional aggression and cyber-victimization and cyber-aggression and by identifying its eventual directionality.

Comparative disposition and metabolism of paraherquamide in sheep, gerbils, and dogs.

The disposition and metabolism of paraherquamide (PHQ), a potent and broad-spectrum anthelminthic, were examined in sheep, dogs, and gerbils. The metabolism of PHQ in these species was extensive and marked by significant species differences both in vitro and in vivo. In sheep and gerbils, PHQ metabolism occurs mainly at the pyrrolidine moiety, generating several metabolites that, for the most part, retained nematodicidal activity in vitro.

A novel 4-oxo-2(E)-nonenal-derived endogenous thiadiazabicyclo glutathione adduct formed during cellular oxidative stress.

Cellular oxidative stress causes increased lipid peroxidation with the concomitant formation of DNA and protein reactive bifunctional electrophiles. Glutathione (GSH) detoxifies these bifunctional electrophiles by forming GSH adducts. Several years ago we discovered 4-oxo-2(E)-nonenal (ONE) as a major bifunctional electrophile derived from lipid hydroperoxides.

Application of LC-NMR for the study of the volatile metabolite of MK-0869, a substance P receptor antagonist.

LC-NMR was applied to identify the polar volatile metabolite of MK-0869. MK-0869, a morpholine-based compound containing a triazolone ring, is a very potent NK(1) receptor antagonist. Currently, it is in development as an anti-emesis agent in chemotherapy treatments.

Identification of metabolites of a substance P (neurokinin 1 receptor) antagonist in rat hepatocytes and rat plasma.

[3R,5R,6S]-3-(2-cyclopropyloxy-5-trifluoromethoxyphenyl)-6-phenyl-1-oxa-7-azaspiro[4.5]decane is a substance P (Neurokinin 1 receptor) antagonist. Substance P antagonists are proven in concept to have excellent potential for the treatment of major depression, and they allow superior and sustained protection from acute and delayed chemotherapy-induced emesis.

Incorporation of stable organic radicals into cyclotriphosphazene: preparation and characterization of mono- and diradical adducts.

Stable cyclotriphosphazenes 4 and 5, incorporating one and two carbon radical centers, respectively, have been easily prepared and characterized. EPR spectroscopic studies in fluid solution at room temperature were carried out for both compounds and also for diradical 5 in frozen solvent matrixes. Spectral results are consistent with a triplet or degenerate singlet triplet ground state for 5.

Complete reduction of oscillators in resonance p:q.

This paper extends to any type of resonance (p:q) the Lissajous transformation that handles the resonance (1:1) in a Hamiltonian composed of two harmonic oscillators. The manifolds of constant energy for such a system are two-dimensional surfaces of revolution that are spheres for the resonance 1:1, spheres pinched once for the resonances (1:q) when 1 View Article and Find Full Text PDF

Bifurcations in biparametric quadratic potentials. II.

Quadratic Hamiltonians with the phase space on the S (2) sphere represent numerous dynamical systems. There are only two classes of quadratic Hamiltonians depending on two parameters. We analyze the occurrence of bifurcations and we obtain the bifurcation lines in the parameter plane for one of these classes, thus complementing the work done in a previous paper where the other class was analyzed.

Bifurcations in biparametric quadratic potentials.

Numerous dynamical systems are represented by quadratic Hamiltonians with the phase space on the S (2) sphere. For a class of these Hamiltonians depending on two parameters, we analyze the occurrence of bifurcations and we obtain the bifurcation lines in the parameter plane. As the parameters evolve, the appearance-disappearance of homoclinic orbits in the phase portrait is governed by three types of bifurcations, the pitchfork, the teardrop and the oyster bifurcations.
