Alcohol consumption is the leading risk factor for morbi‐mortality in many Latin American Countries. However, epidemiologic studies are relatively scarce. Among factors such as limited research capacity, disciplinary traditions and an emphasis on psychopathology within the field of psychology, have been postulated to account for this. The aim of this article is to review epidemiologic research on alcohol in Spanish Speaking Latin American Countries, and to measure the contribution of psychology to the field. A systematic search was performed in English and Spanish using regional and international data bases. We identified 269 articles. Most focused on consumption patterns in youth, with samples from a single school and using a variety of measures. With the exception of multinational efforts like Emergency Room Collaborative Alcohol Analysis Project or those supported by World Health Organization/Pan American Health Organization, studies reviewed reflected little cross country collaboration. Mexico accounted for most of the productivity, while many countries had very few or no articles. Most research was performed by health science researchers with a small contribution from psychology, but which increased significantly over time. The results of this review provide a broad identification of patterns regarding epidemiologic research on alcohol, and demonstrate the need for national scientific policies to promote research on public health topics. 相似文献

Symbols are communicative tools with performative functions in all cultures. Apart from their decorative functions, non‐Christian symbols adopted into Christianity have had a tremendous impact on Christian life since the early times, especially in liturgical practices. Through Western missionary activities, Ghana inherited Christian biblical‐liturgical art as has been developed in the home countries of the missionaries. However, since the 1960s Adinkra symbols have been incorporated into Christian worship and theology, receiving attention within secular and religious circles because of their communicative potential. On the religious level, some churches have adopted them as logos or incorporated them into architectural designs and liturgical art. This paper seeks to investigate what motivates various missions to choose particular Adinkra symbol(s) and what they hope to achieve with them. Furthermore, it attempts a theological reflection on the communicative potential of artefacts in Ghanaian Christianity as a response to the “Great Commission. “We approach the subject from a historical, contextual, and theological perspective, using selected Roman Catholic and Methodist churches in Ghana as case studies. The study employed unstructured in‐depth interviews and photo elicitations to trace the relationship between visual arts and religion, with particular emphasis on Christian visual arts and how they have informed Christianity in Ghana. 相似文献

Sierra Leone has endured a turbulent history, including a decadelong civil war and the devastation of Ebola virus disease. Despite the psychological consequences of such events, only limited therapeutic services are available. The authors review mental health services in Sierra Leone and document the emergence of counseling as a profession in the face of challenges. They conclude by highlighting the multiple contributions that professional counselors can make to address critical mental health needs in Sierra Leone. 相似文献

The effect of student‐to‐school‐counselor ratios on academic outcomes has been widely studied, yet few researchers have taken a multilevel approach. Using the nationally representative High School Longitudinal Study: 2009 dataset, the authors found ratios were significantly associated with student grade point average (GPA) and graduation. Attending a Title I school also was associated with students’ GPA, advanced placement/international baccalaureate credits earned, and postsecondary course taking. The authors discuss implications for advocacy and practice, contextualizing their findings within an ecological framework. 相似文献

We investigate the emergence of iconicity, specifically a bouba‐kiki effect in miniature artificial languages under different functional constraints: when the languages are reproduced and when they are used communicatively. We ran transmission chains of (a) participant dyads who played an interactive communicative game and (b) individual participants who played a matched learning game. An analysis of the languages over six generations in an iterated learning experiment revealed that in the Communication condition, but not in the Reproduction condition, words for spiky shapes tend to be rated by naive judges as more spiky than the words for round shapes. This suggests that iconicity may not only be the outcome of innovations introduced by individuals, but, crucially, the result of interlocutor negotiation of new communicative conventions. We interpret our results as an illustration of cultural evolution by random mutation and selection (as opposed to by guided variation). 相似文献

Are Words Easier to Learn From Infant‐ Than Adult‐Directed Speech? A Quantitative Corpus‐Based Investigation

We investigate whether infant‐directed speech (IDS) could facilitate word form learning when compared to adult‐directed speech (ADS). To study this, we examine the distribution of word forms at two levels, acoustic and phonological, using a large database of spontaneous speech in Japanese. At the acoustic level we show that, as has been documented before for phonemes, the realizations of words are more variable and less discriminable in IDS than in ADS. At the phonological level, we find an effect in the opposite direction: The IDS lexicon contains more distinctive words (such as onomatopoeias) than the ADS counterpart. Combining the acoustic and phonological metrics together in a global discriminability score reveals that the bigger separation of lexical categories in the phonological space does not compensate for the opposite effect observed at the acoustic level. As a result, IDS word forms are still globally less discriminable than ADS word forms, even though the effect is numerically small. We discuss the implication of these findings for the view that the functional role of IDS is to improve language learnability. 相似文献

The common ground that conversational partners share is thought to form the basic context for language use. According to the classic view, inferences about common ground, or mutual knowledge, are guided by beliefs about the physical, cognitive, and attentional states of one's communicative partners. Here, we provide a first test of the attention assumption for common ground, the proposal that common ground for a co‐present entity—such as an object or an utterance—can only be formed if a person has evidence that his or her partner has also attended to it. In three experiments, a participant speaker and two partners learned names for novel monster pictures as a group. The speaker was then asked to describe the monsters to each partner separately in a referential communication task. The critical manipulation was the (in)attentiveness of one partner at different points in the study. Analysis of the speaker's referring expressions revealed that speakers assumed their partner shared common ground for the monster names only when that partner exhibited engaged attention as the names were learned. These findings provide key and novel support for the classic proposal that formation of common ground critically depends on assumptions about the attentional state of one's conversational partner. 相似文献

Cultural Effects Rather Than a Bilingual Advantage in Cognition: A Review and an Empirical Study

The bilingual advantage hypothesis contends that the management of two languages in the brain is carried out through domain‐general mechanisms, and that bilinguals possess a performance advantage over monolinguals on (nonlinguistic) tasks that tap these processes. Presently, there is evidence both for and against such an advantage. Interestingly, the evidence in favor has been thought strongest in children and older adults, leading some researchers to argue that young adults might be at peak performance levels, and therefore bilingualism is unable to confer an improvement. We conducted a large‐scale review of the extant literature and found that the weight of research pointed to an absence of positive evidence for a bilingual advantage at any age. We next gave a large number of young adult participants a task designed to test the bilingual advantage hypothesis. Reasoning from the literature that young adults from an East Asian (Korean) culture would likely outperform those from a Western (British) culture, we also compared participants on this factor. We found no evidence for a bilingual advantage but did find evidence for enhanced performance in the Korean group. We interpret these results as further evidence against the bilingual advantage hypotheses. 相似文献
