Background: The International Index of Erectile Function (IIEF) stands out for its utility and widespread use to measure sexual function in men. However, it lacks consistency in its internal latent structure across studies, has not been evaluated for measurement invariance, and has not undergone psychometric validation for its 15-item form in Spanish among South American countries.
Aim: To examine the IIEF's psychometric evidence (ie, structural/criterion validity and reliability) in a sample of adult men and determine its measurement invariance across relationship status (single vs in a relationship) and age generations (generations Z, Y/millennials, and X).
Given the ubiquitous nature of love, numerous theories have been proposed to explain its existence. One such theory refers to love as a commitment device, suggesting that romantic love evolved to foster commitment between partners and enhance their reproductive success. In the present study, we investigated this hypothesis using a large-scale sample of 86,310 individual responses collected across 90 countries.

Therefore, they are dissolved in organic solvents to reach suitable concentrations in the reaction milieu of the Fenton system. However, these solvents may react with •OH and iron, leading to significant errors in the results.

During both periods, friendships play an increasingly significant role and can significantly impact individuals positively or negatively. Despite the evolving nature of these relationships, parents remain crucial to the development of both adolescents and emerging adults, playing a key role in their well-being.

The generation of •OH and light emission due to oxidative damage to EGTA may depend on the buffer and pH of the reaction milieu. In this study, we evaluated the effect of pH from 6.

Guided by this perspective, we examined in a multinational and multicultural study (61 countries; N = 15,039) how narcissism forms are linked to cognitions and behaviors prompted by the COVID-19 pandemic. As expected, differences in cognitions and behaviors across narcissism forms emerged.

Our overarching goal was to analyze contemporary perceptions of masculinity and femininity using quantitative and qualitative methods, marking a groundbreaking effort in social science research. The data collection took place between January 2018 and February 2020, and involved undergraduate students who completed a series of randomized scales and the data was collected through the SurveyMonkey or Qualtrics platforms, with paper surveys being used in rare cases.

The present study examined associations among attitudes toward sugar relationships and relevant variables (e.g.

Kidney transplantation reduces oxidative stress and HO production by blood polymorphonuclear leukocytes (PMNs). Kidney transplant recipients (KTRs) may be predisposed to an impairment of lung diffusing capacity due to chronic inflammation.

Because loneliness has been suggested to be both commonly experienced and detrimental, we examine if there are similar patterns between humor styles, gender, and age with loneliness in samples of individuals from diverse backgrounds. Across the country samples, affiliative and self-enhancing humor styles negatively correlated with loneliness, self-defeating was positively correlated, and the aggressive humor style was not significantly related.

In this scenario, the general objective of this cross-cultural longitudinal study is to examine the relationship between identification with proximate categories (i.e.

Plant polyphenols reveal the afore-mentioned activities, and their cumulative net effect may determine anti- or pro-oxidant actions. We investigated the influence of 17 phenolics on ultra-weak photon emission (UPE) from a modified Fenton system (92.

Greene et al. (2009) showed that psychological and situational factors (for example, the intent of the agent or the presence of physical contact between the agent and the victim) can play an important role in moral dilemma judgements (for example, the trolley problem).

We asked whether the measurement of this fear is trustworthy and comparable across countries. In particular, we explored the measurement invariance and cross-cultural replicability of the widely used Fear of COVID-19 scale (FCV-19S), testing community samples from 48 countries (N = 14,558).

Objective: This participatory research sought to understand how engagement in awareness-raising multicultural activities strengthens well-being and group efficacy among immigrants and host nationals. We also examined the mediating role of self-transcendent emotions and shared flow.
Method: We tested our predictions across three studies, each focused on one awareness-raising activity organized by a nongovernmental organization, SOS Racismo-Mugak, working closely with the local community.
Fomitopsis officinalis is a popular species of therapeutic arboreal mushroom with a documented history of use in traditional European and Asian medicine. It was chosen as a research material not only due to its anti-inflammatory, antimicrobial, and immunostimulatory properties but also because it is endangered in Poland. The aim of this study was to determine the effects of supplementing inorganic zinc and magnesium salts to the culture medium in which F.

However, in the presence of Fe/Fe ions and HO, it may behave as a pro-oxidant by accelerating and enhancing the formation of hydroxyl radicals (OH). Therefore, in this study we evaluated the effect of AA at concentrations of 1 to 200 µmol/L on OH-induced light emission (at a pH of 7.

In this model, two dimensions (valence and dominance) underpin social judgements of faces. Because this model has primarily been developed and tested in Western regions, it is unclear whether these findings apply to other regions.
