英语学习切忌机械对应

所谓机械对应,就是英语学习者在头脑里自觉或不自觉地把某个汉语词和某个英语词划上了等号。这在英语学习中是一种普遍存在的错误倾向,它严重地阻碍着我们整体英语水平的提高。机械对应的起源可以追溯到英语课本中常见的汉英对照词汇表。比如把单词wear解释为"穿",把level解释成"水

Serious case reviews: learning to use expertise

While undertaking an analysis of 20 serious case reviews for the Welsh Assembly Government, the authors became aware of important, largely unexplored, practice issues with implications for training, service delivery and the role of the lead professional. The reviews were studied using a ‘layered reading’ methodology to ensure that emerging themes were grounded entirely in the reports. In looking beyond the familiar recurring themes and practice failings, findings emerged about the use of expertise in its widest sense. The need for more skilled use of expertise was identified, from external specialists and child protection specialists, and from children, siblings and parents. Professionals from agencies who contribute less routinely to the process of safeguarding children should be consulted as experts and be empowered to play a fuller part. Consultation could often be used prior to, or in place of referral. The barrier to the collation and analysis of relevant information often appeared to be a failure to recognize and understand expertise rather than a lack of communication as often postulated in review reports. Skilled use of expertise and consultation in a coordinated manner could result in more rigorous assessments and promote greater professional trust, confidence and challenge.

Media use and political learning: Comparing Trump supporters to celebrity candidate voters

This study examines whether political media use behaviors of voters who supported Donald Trump in the 2016 presidential election align with those of “celebrity candidate voters” portrayed in the literature. The study used a national online survey (N = 1,608) conducted during the 2016 primary, and findings reveal that Trump supporters, more than other voters, are driven by entertainment motivations and follow campaign news using entertainment media: specifically, the video-sharing site YouTube. Although Trump voters are interested in the campaign, their level of political knowledge is lower than other voters, and no one media outlet made a significant contribution to their learning. A comparison group of other voters showed significant knowledge gains from news websites and Twitter. Results for Trump voters are consistent with scholars’ characterization of the celebrity candidate audience, particularly in studies suggesting that celebrity politicians may increase citizens’ engagement through entertainment gratifications rather than by a desire to become informed.     

The road to a world health organization global strategy for reducing the harmful use of alcohol

Harmful alcohol use and the related health effects are a global problem and therefore need to be addressed not only by individual nations but also on an international level. For example, the World Health Organization (WHO) noted that harmful alcohol use is the third leading risk factor for premature deaths and disabilities in the world, accounting for approximately 2.5 million deaths worldwide (corresponding to 3.8 percent of all deaths) in 2004 (WHO 2010). Moreover, harmful alcohol use was considered responsible for 4.5 percent of the global burden of disease as measured in disability-adjusted life-years lost in the same year. Given this scope of the impact, the WHO initiated a series of efforts that culminated in the development of a global strategy for reducing the harmful use of alcohol. This article reviews the alcohol-related activities of the WHO over the years and summarizes the central issues addressed by the global strategy.     

Efficient and effective learning for safety from incidents

Learning from incidents is important for improving safety. Many companies spend a great deal of time and money on such learning procedures. The objectives of this paper are to present some early results from a project aimed at revealing weaknesses in the procedures for learning from incidents and to discuss improvements in these procedures, especially in chemical process industries. The empirical base comes from a project assessing organizational learning and the effectiveness of the different steps of the learning cycle for safety and studying relations between safety-specific transformational leadership, safety climate, trust, safety-related behavior and learning from incidents. The results point at common weaknesses in the organizational learning, both in the horizontal learning (geographical spread) and in vertical learning (double-loop learning). Furthermore, the effectiveness in the different steps of the learning cycle is low due to insufficient information in incident reports, very shallow analyses of reports, decisions that focus at solving the problem only at the place where the incident took place, late implementations and weak solutions. Strong correlations with learning from incidents were found for all safety climate variables as well as for safety-related behaviors and trust. The relationships were very strong for trust, safety knowledge, safety participation and safety compliance.     

Mothers' use of touch across infants' development and its implications for word learning: Evidence from Korean dyadic interactions

Caregivers' touches that occur alongside words and utterances could aid in the detection of word/utterance boundaries and the mapping of word forms to word meanings. We examined changes in caregivers' use of touches with their speech directed to infants using a multimodal cross-sectional corpus of 35 Korean mother-child dyads across three age groups of infants (8, 14, and 27 months). We tested the hypothesis that caregivers' frequency and use of touches with speech change with infants' development. Results revealed that the frequency of word/utterance-touch alignment as well as word + touch co-occurrence is highest in speech addressed to the youngest group of infants. Thus, this study provides support for the hypothesis that caregivers' use of touch during dyadic interactions is sensitive to infants' age in a way similar to caregivers' use of speech alone and could provide cues useful to infants' language learning at critical points in early development.     

Condom negotiation strategy use and effectiveness among college students

College students may engage in risky sexual behaviors, such as inconsistent condom use, which increase their risk of sexually transmitted infections. This study examined the association between six condom influence strategies (CIS) and reported condom use among a diverse group of college students. Differences in CIS and condom use were examined by gender, race or ethnicity, and relationship status (casual, monogamous, or no current relationship). The study also used a cluster analysis to investigate how the CIS were used relative to one another, and how patterns of CIS use were related to condom use. Results showed interesting differences in CIS use by gender, race or ethnicity, and relationship status. Four patterns of CIS usage emerged, and results suggested that using all CIS frequently and using more assertive CIS may be particularly important for increased condom use. Men reported more condom use than women overall, but results indicated that using CIS were especially vital for increasing condom use for women. Surprisingly, there were no differences in condom use found for race or ethnicity and relationship type. Programs aimed at increasing students' condom use could benefit from promoting and practicing CIS, and recognizing potential differences among demographic groups.     

The use software ERGOSHOW in the education of health and safety at work to regardin the safety to children

It is believed that health and safety of workers should be worked with children and early teenagers, the perspective that adults are more aware of these issues by providing them with health and quality of life in their daily lives, this is want the ERGOSHOW. The choice of media means for transmitting content of Ergonomics, Health and Safety (OSH) is justified because of the great popularity of computer games are among the public of the study, thereby providing a greater assimilation of the content worked. Therefore, the aim of this study was to work with OSH issues related to children between 08 and 12 years old, city of, State of Minas Gerais, Brazil. To achieve this we used the software ERGOSHOW, quizzes, and lecture. One can see that the use of multimedia tools in the learning, especially when considering the reports of mothers according to the different behavior of children after the development of activities, such as parents in correcting posture in relation to computer use.
