This study examines some of the perceptions amongst Spanish LGBTQ+ youth during the first wave of the COVID-19 pandemic and the subsequent confinement and lockdown measures, between March and May 2020. During this time, many of these young people were forced to return to their family homes and restrict their social relations. This new situation often exposed them to forms of violence from which there was no escape, with negative consequences for their psychosocial health. The study evaluates the correlations between (...) perceived social support, burdensomeness, thwarted belongingness and the people with whom LGBTQ+ youth lived during confinement. A descriptive and multivariate analysis of variance and bivariate correlations is used to examine the responses of 394 LGBTQ+ youth, between 17 and 21 years of age, residing in Spain. Overall, the study finds that gender is key when explaining the differences between the experiences of LGBTQ+ youth, with women and non-binary individuals experiencing a greater perception of stigma in the places where they lived during the lockdown. Moreover, trans men and women and non-binary individuals reported receiving less support and a greater feeling of burdensomeness then the other participants. These results suggest that LGBTQ+ youth must be given special consideration during times of crisis, like the COVID-19 pandemic, and may benefit from intervention with an intersectional and transfeminist perspective.

Research Ethics Committees (RECs) are frequently a focus of complaints from researchers, but evidence about the operation and decisions of RECs tends to be anecdotal. We conducted a systematic study to identify and compare the ethical issues raised in 54 letters to researchers about the same 18 applications submitted to three RECs over one year. The most common type of ethical trouble identified in REC letters related to informed consent, followed by scientific design and conduct, care and protection of research (...) participants, confidentiality, recruitment and documentation. Community considerations were least frequently raised. There was evidence of variability in the ethical troubles identified and the remedies recommended. This analysis suggests that some principles may be more institutionalized than others, and offers some evidence of inconsistency between RECs. Inconsistency is often treated as evidence of incompetence and caprice, but a more sophisticated understanding of the role of RECs and their functioning is required. (shrink)

In this paper a formalized logic of propositions, PA1, is presented. It is proven consistent and its relationships to traditional logic, to PM ([15]), to subjunctive (including contrary-to-fact) implication and to the “paradoxes” of material and strict implication are developed. Apart from any intrinsic merit it possesses, its chief significance lies in demonstrating the feasibility of a general logic containing theprinciple of subjunctive contrariety, i.e., the principle that ‘Ifpwere true thenqwould be true’ and ‘Ifpwere true thenqwould be false’ are incompatible.

ABSTRACT Various mechanisms to ensure the protection of subjects in human research have been suggested, including the presence of witnesses during the informed consent process. For our commentary on the use of witnesses and their potential role and responsibility during the consent process, we start by addressing current guidelines for human subjects research in four Latin American countries. By using examples from public health research, we highlight some of the practical difficulties of using witnessed consent, from becoming a meaningless ritual (...) at one end of the spectrum to the research subject feeling intimidated or coerced to participate at the other. Apart from these practical difficulties, it is unclear what responsibility the witness could and should have. We argue that there are important ethical questions about the role of witnesses that have not been adequately addressed in national and international regulations. This work addresses these gaps and argues that more debate is required to define the role and responsibilities of witnesses in the consent process, their training requirements and whether a universal legal requirement for witnessed consent, regardless of the type of research, is desirable.

Anyone, today, with even a slight interest in the methodology of science will be aware of the heated debate which has raged in regard to the thesis of the logical symmetry between explanation and prediction, which is entailed by the hypotheticodeductive account of scientific theory. The symmetry thesis, which received its classical exposition in a well-known article by Hempel and Oppenheim [2], has been subject to a steadily growing criticism by several eminent thinkers. My intention, in this article, is to (...) argue that the current reaction to the Hempel-Oppenheim position, as exemplified by Professors Hanson, Scriven, et al., represents a retrograde movement in the philosophy of science, which, as the number of its converts grows, could undermine the progress, which has been accomplished in the broad tradition that extends from Mach and Poincaré through the Vienna Circle to the present day. Specifically, it is my contention that the aforementioned reaction is symptomatic of a contemporary trend in the direction of irrationalism which, of all branches of philosophy, the philosophy of science should seek to dispel rather than to foster. For the sake of brevity, I propose to focus my remarks wholly on the original widely read article of Hanson on this subject [1]. That I single out this particular source should not be taken to belie the admiration I hold for the masterful scholarship of its author. (shrink)

Philosophers have long debated whether, if determinism is true, we should hold people morally responsible for their actions since in a deterministic universe, people are arguably not the ultimate source of their actions nor could they have done otherwise if initial conditions and the laws of nature are held fixed. To reveal how non-philosophers ordinarily reason about the conditions for free will, we conducted a cross-cultural and cross-linguistic survey (N = 5,268) spanning twenty countries and sixteen languages. Overall, participants tended (...) to ascribe moral responsibility whether the perpetrator lacked sourcehood or alternate possibilities. However, for American, European, and Middle Eastern participants, being the ultimate source of one’s actions promoted perceptions of free will and control as well as ascriptions of blame and punishment. By contrast, being the source of one’s actions was not particularly salient to Asian participants. Finally, across cultures, participants exhibiting greater cognitive reflection were more likely to view free will as incompatible with causal determinism. We discuss these findings in light of documented cultural differences in the tendency toward dispositional versus situational attributions. (shrink)

Purpose This study aims to understand the allure and danger of fake news in social media environments and propose a theoretical model of the phenomenon. Design/methodology/approach This qualitative research study used the uses and gratifications theory approach to analyze how and why people used social media during the 2016 US presidential election. Findings The thematic analysis revealed people were gratified after using social media to connect with friends and family and to gather and share information and after using it as (...) a vehicle of expression. Participants found a significant number of fake news stories on social media during the 2016 US presidential election. Participants tried to differentiate between fake news and real news using fact-checking websites and news sources and interacted with the social media users who posted fake news and became part of the echo chamber. Behaviors like these emerged in the analysis that could not be completely explained by UGT and required further exploration which resulted in a model that became the core of this study. Research limitations/implications This is a small-scale exploratory study with eight diverse participants, findings should not be generalized to larger populations. Time-specific self-reporting of information from social media and fake news during the 2016 US presidential election. Upgrading public policies related to social media is recommended in the study, contributing to burgeoning policy discussions and provides recommendations for both purveyors of social media and public policymakers. Practical implications Upgrade in public policies related to social media is recommended in the study and contributes to burgeoning policy discussions and provides recommendations for both purveyors of social media and public policymakers. Social implications Social media users are spending increased time on their preferred platforms. This study increases the understanding of the nature, function and transformation of virtual social media environments and their effects on real individuals, cultures and societies.What is original/of value about the paper?This exploratory study establishes the foundation on which to expand research in the area of social media use and fake news.

Angiogenesis plays an essential role in tumor growth, invasion and metastasis. After initial pessimism about the usefulness of the antiangiogenic therapeutic approach for cancer, interest has increased in the development of antiangiogenic compounds after the first clinical approval of an antiangiogenic therapy. The anti‐vascular endothelial growth factor (VEGF) antibody bevacizumab has recently been approved for use in combination with chemotherapy for the treatment of metastatic colorectal and non‐small cell lung cancer patients. However, no survival benefit has been demonstrated in anti‐VEGF (...) monotherapy trials, probably due to the high complexity of tumor angiogenesis regulation. Experimental and clinical data, including the approval of the multitargeted drugs sunitinib and sorafenib, indicate that exciting results, including tumor regression, can be expected from the combined targeting of different pathways in the tumor angiogenesis scenario. Several obstacles, including the high cost of new molecular targeted drugs make this therapeutic approach difficult. BioEssays 29:1159–1168, 2007. © 2007 Wiley Periodicals, Inc. (shrink)

This study investigates the relationship between mental health and emotional intelligence among senior high school students in a public school. Thus, the study employed a correlational design to measure the relationship between mental health and emotional intelligence among 152 Grade 12 senior high school students in a public school.

Based on the inferential statistics, the r coefficient of 0.32 indicates a low positive correlation (...) between the variables and a p-value of 0.00, indicating a significant relationship between the respondents' mental health and emotional intelligence. Implications and recommendations were discussed in the study. (shrink)

According to kin selection theory, indirect reproductive advantages may induce individuals to care for others with whom they share genes by common descent, and the amount of care, including self-sacrifice, will increase with the proportion of genes shared. Twins represent a natural situation in which this hypothesis can be tested. Twin pairs experience the same early environment because they were born and raised at the same time and in the same family but their genetic relatedness differs depending on zygosity. We (...) compared the degree of willingness to fight and sacrifice for the co-twin among monozygotic and dizygotic pairs in a sample of 1443 same-sex and opposite-sex twins. We also analyzed the effect of the subject’s gender and that of the co-twin on those altruistic behaviors. Results partly supported the postulated explanation. MZ twins were significantly more likely than DZ twins to self-sacrifice for their co-twins, but zygosity did not affect willingness to fight for him/her. The genders of the subject and of the co-twin, not genetic relatedness, were the best predictors of aggressive altruistic intentions. (shrink)

Because of the COVID-19 pandemic, procrastination has become commonplace due to changes in teaching and learning, which trigger students' academic burnout. As a result, it has increased the intensity of procrastination among students who are enrolled in online learning programs. As a result, students have difficulty as a result of the rapid change from in-person learning to online learning. The study investigates the relationship between academic burnout and procrastination among 150 grade 12 senior high school students. Hence, this study employed (...) a correlational design. Based on the inferential analysis, the r coefficient of 0.71 indicates a high positive correlation between the variables. The p-value of 0.00, which is less than 0.05, leads to the decision to reject the null hypothesis. Hence, a significant relationship exists between academic burnout and academic procrastination among grade 12 senior high school students. (shrink)
