Normal and Maladaptive Personality Traits as Predictors of Motives for Social Media Use and Its Effects on Well-Being.

This study aimed to identify the motives for social media sites use in the general population and determine what personality traits (normal and maladaptive) predict different motives for social media sites use. Another objective was to analyze which motives for SMSs use are related to well-being. The sample consisted of 420 subjects (211 men, 209 women), mean age 40.

State, but not trait gratitude is associated with cardiovascular responses to acute psychological stress.

Recent research suggests that gratitude is associated with better cardiovascular health. Here, we investigated whether trait and/or state gratitude was associated with cardiovascular responses to acute stress. Eighty-six young adults completed measures of gratitude and had their cardiovascular responses monitored throughout a standardized stress testing protocol.

Dysfunctional personality traits: relationship with Five Factor Model, adaptation and symptomatology in a community sample from Buenos Aires.

The paper introduces an analysis of the dimensional maladaptive personality traits model stated in the section III of Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5), conducted on a community sample composed of 906 adults from Buenos Aires, Argentina. Data were gathered using a socio-demographic survey as well as the Personality Inventory for DSM-5 (PID-5), the Big Five Inventory (BFI), the Symptom Check List 90-R (SCL-90-R), and the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.

Do Transgender People Respond According to Their Biological Sex or Their Gender Identity When Confronted With Romantic Rivals?

This study examined the hypothesis that gender identity and biological sex represent independent modules and that transgender individuals respond to romantic rivals in line with their gender identity and not with their biological sex. Additionally, associations of jealousy with intrasexual competitiveness (ISC) and social comparison orientation (SCO) were explored. A total of 134 male-to-female and 94 female-to-male transgender individuals from Greater Buenos Aires, Argentina, responded to a questionnaire.

PERSONALITY ASSESSMENT INVENTORY: PSYCHOMETRIC ANALYSES OF ITS ARGENTINEAN VERSION.

This psychometric analysis of the Argentinean version of the Personality Assessment Inventory employed a convenience sample of 998 non-clinical adults from Buenos Aires, Argentina, stratified by sex and age (50% men; M age = 40.4 yr., SD = 16.

Preparation of alginate-chitosan fibers with potential biomedical applications.

The preparation of alginate-chitosan fibers, through wet spinning technique, as well as the study of their properties as a function of chitosan's molecular weight and retention time in the coagulation bath, is presented and discussed in this work. Scanning electron microscopy (SEM) revealed that the fibers presented irregular and rough surfaces, with a grooved and heavily striated morphology distributed throughout the structure. Dynamic mechanical analysis (DMA) showed that, with the exception of elongation at break, the incorporation of chitosan into the fibers improved their tensile properties.

Dent-Wrong disease and other rare causes of the Fanconi syndrome.

Dent-Wrong disease, an X-linked recessive disorder of the proximal tubules, presents with hypercalciuria, nephrocalcinosis, nephrolithiasis, renal insufficiency, low-molecular-weight proteinuria, rickets and/or osteomalacia. Dent and Friedman initially characterized the disorder in 1964 following studies of two patients with rickets who presented with hypercalciuria, hyperphosphaturia, proteinuria and aminoaciduria. Since then, extensive investigation identified two genetic mutations (CLCN5 and OCRL1) to be associated with Dent-Wrong disease.

Character strengths: a study of Argentinean soldiers.

The primary objective of this research was to study the differences in positive traits between military and civilian college students and between cadets in their first and final years at a military academy. Second, the research aimed to study the relations between positive traits and the academic and military performance of cadets in their first and final years, according to the classification of positive traits by Peterson and Seligman (2004). To accomplish these objectives, a sample of university students from a military educational institution and a sample of civilian university students were studied.

Conflicting preferences of parents and offspring over criteria for a mate: a study in Argentina.

Current evolutionary research on human mating has largely ignored the fact that mating decisions may be heavily influenced by parents. Recent research, however, shows that parents and children may have conflicting mate preferences. Specifically, parents tend to have a relatively stronger preference for children to pair with mates with characteristics signaling high parental investment and cooperation with the in-group, whereas children tend to have a relatively stronger preference to pair with mates with characteristics signaling genetic quality.

Remote position substituents as modulators of conformational and reactive properties of quinones. Relevance of the pi/pi intramolecular interaction.

Several studies have described that quinoid rings with electron-rich olefins at remote position experience changes in their redox potential. Since the original description of these changes, different approaches have been developed to describe the properties of the binding sites of ubiquinones. The origin of this phenomenon has been attributed to lateral chain flexibility and its effect on the recognition between proteins and substrates associated with their important biological activity.
