Like predatory journals, predatory conferences are a growing part of the academic landscape, but unlike their journal counterparts, to date predatory conferences have not been extensively investigated, and many unanswered questions about their workings exist. From a positive ethics perspective, a more complete understanding of predatory conferences is desirable, as it can support researchers in making ethically appropriate choices about conference attendance. Ten predatory conference organisations were the focus of this study. The investigation first set out to identify and document the attributes of such conferences. They were then analysed to understand which attributes can most easily and reliably be used to distinguish them from legitimate conferences. A tool to assist prospective participants is introduced. The implications for positive ethics, in terms of making decisions about conference attendance, are discussed.

Mixed methods refers to the use of both qualitative and quantitative approaches and methods in one study or sequentially in two or more studies. Without a mixed methods approach there is – to our minds ‐ a risk that only part of a phenomenon or experience is being explored. Our own involvement in mixed methods research has grown out of a shared interest in the concept ‘research‐practitioner’. Psychotherapy is a notoriously complex and ever‐developing field, and our growing sense has been that mixed methods research can contribute to a more complete – both broad and deep ‐ sense of knowledge and understanding.  相似文献

Loneliness is a significant public health issue that affects young adults. This investigation drew from interpersonal acceptance-rejection theory to understand how remembrances of parental rejection contributed to psychological maladjustment and loneliness in Bangladeshi college students (N = 300; 50% female). Students reported their remembrances of mothers' and fathers' acceptance-rejection, their current psychological maladjustment, and loneliness. Remembrances of rejection by parents in childhood were associated with psychological maladjustment (hostility/aggression, negative self-esteem, negative self-adequacy, emotional unresponsiveness, emotional instability, and negative worldview) for young adult men and women. Psychological maladjustment, in turn, was associated with feelings of loneliness in young adulthood for young men, but not women. Remembrances of parental rejection were also associated with greater hostility and aggression over and above general psychological functioning among both men and women. Findings are discussed in the context of different social and structural features of young adulthood for women and men in Bangladesh.  相似文献

Large health disparities exist between stigmatized and nonstigmatized groups. In addition to experiencing and anticipating greater discrimination, members of stigmatized groups also tend to demonstrate greater ruminative tendencies in response, which may lead to these poor health outcomes. Even among stigmatized groups, differences in the visibility of stigma lead to different mechanisms through which stigma takes its toll. Previous work has primarily focused on the impact of belonging to a single marginalized group; however, people often belong to multiple marginalized groups, and this likely affects both their health outcomes and their anticipation of stigma. In the current study, we focused on individuals with concealable stigmatized identities (CSIs)—socially stigmatized identities that are not immediately apparent to others—and created a measure of concealable marginalization that captures multiple group memberships. We predicted that those possessing a greater number of CSIs would anticipate more stigma from others, and, in turn, ruminate more about the stigma, which would negatively impact the health. Surveying N = 288 adults with CSIs, we found that possessing a greater number of marginalized concealable identities predicted worse self-reported physical quality of life. These relationships were partially mediated by greater anticipated stigma and brooding rumination in regard to their CSI. This work illuminates a more complete picture of how living with CSIs can take its toll on health.  相似文献

Job advertising is a common and useful recruitment marketing method that is available to a wide range of candidates and offers a practical way to widen the applicant pool. Frequently, retail advertisements only briefly introduce job requirements, but others provide more detailed information. Existing message studies, however, are inconclusive about the effectiveness of message specificity. A scenario‐based experiment that included 164 participants revealed that the type of decision maker (maximizer or satisficer) moderates the specificity effects in recruitment messages. After receiving a detailed job message, more satisficers stop their search process, but only maximizers perceive the company as more attractive and increase intentions toward the advertised job. A follow‐up qualitative study involving 30 participants provided further insights.  相似文献

This paper describes conceptual, methodological, and practical insights from a longitudinal social psychological project that aims to build cardiovascular disease (CVD) competence in a poor community in Accra, Ghana's capital. Informed by a social psychology of participation approach, mixed method data included qualitative interviews and household surveys from over 500 community members, including people living with diabetes, hypertension, and stroke, their caregivers, health care providers, and GIS mapping of pluralistic health systems, food vending sites, bars, and physical activity spaces. Data analysis was informed by the diagnosis‐psychosocial intervention‐reflexivity framework proposed by Guareschi and Jovchelovitch. The community had a high prevalence of CVD and risk factors, and CVD knowledge was cognitive polyphasic. The environment was obesogenic, alcohol promoting, and medically pluralistic. These factors shaped CVD experiences and eclectic treatment seeking behaviours. Psychosocial interventions included establishing a self‐help group and community screening and education. Applying the “AIDS‐competent communities” model proposed by Campbell and colleagues, we outline the psychosocial features of CVD competence that are relatively easy to implement, albeit with funds and labour, and those that are difficult. We offer a reflexive analysis of four challenges that future activities will address: social protection, increasing men's participation, connecting national health policy to community needs, and sustaining the project.  相似文献

In three studies we examined the associations between resource sharing (RS) and attachment, and the enhancement of RS using attachment security primes. In Study 1, we showed that attachment avoidance was negatively associated with RS. We also identified differences and similarities between RS and pro‐sociality. In Studies 2 and 3, we showed that research participants were more likely to share their monetary resources after they were primed with attachment security. Study 3 further revealed that security priming affected mainly people low on state attachment anxiety. Our findings extend previous work on pro‐sociality into the specific realm of RS, provide behavioral evidence, and tie attachment and close relationships in with game theory and research on economic decision making.  相似文献

Sexual coercion is receiving much attention with the #MeToo movement. Not all of the tactics that perpetrators use to coerce sex are perceived to be equally unacceptable. This study examined factors that may mitigate negative perceptions, including features of the perpetrator's tactics (verbal vs. physical tactics, relationship‐focused vs. self‐focused reasons to coerce sex) and raters' own current relationship (commitment, dependence, sexually coercive experiences). College women (N = 498) rated whether the perpetrator's behavior was acceptable, was excusable, and would adversely affect a relationship. Verbal (vs. physical) coercion, dependence on a current partner, and sexually coercive experiences in a current relationship mitigated negative perceptions. However, participant ratings were not influenced by the perpetrator's use of relationship‐focused reasons for coercing sex (vs. self‐focused reasons), suggesting that women may resist male attempts to sugar‐coat sexual coercion.  相似文献

Language acquisition depends on the ability to detect and track the distributional properties of speech. Successful acquisition also necessitates detecting changes in those properties, which can occur when the learner encounters different speakers, topics, dialects, or languages. When encountering multiple speech streams with different underlying statistics but overlapping features, how do infants keep track of the properties of each speech stream separately? In four experiments, we tested whether 8‐month‐old monolingual infants (N = 144) can track the underlying statistics of two artificial speech streams that share a portion of their syllables. We first presented each stream individually. We then presented the two speech streams in sequence, without contextual cues signaling the different speech streams, and subsequently added pitch and accent cues to help learners track each stream separately. The results reveal that monolingual infants experience difficulty tracking the statistical regularities in two speech streams presented sequentially, even when provided with contextual cues intended to facilitate separation of the speech streams. We discuss the implications of our findings for understanding how infants learn and separate the input when confronted with multiple statistical structures.  相似文献
