What We Know about Emotional Intelligence: How It Affects Learning, Work, Relationships, and Our Mental Health

Abstract: Sorting out the scientific facts from the unsupported hype about emotional intelligenceEmotional intelligence (or EI)?the ability to perceive, regulate, and communicate emotions, to understand emotions in ourselves and others?has been the subject of best-selling books, magazine cover stories, and countless media mentions It has been touted as a solution for problems ranging from relationship issues to the inadequacies of local schools But the media hype has far outpaced the scientific research on emotional intelligence In What We Know about Emotional Intelligence, three experts who are actively involved in research into EI offer a state-of-the-art account of EI in theory and practice They tell us what we know about EI based not on anecdote or wishful thinking but on scienceWhat We Know about Emotional Intelligence looks at current knowledge about EI with the goal of translating it into practical recommendations in work, school, social, and psychological contexts

Nutrient requirements for growth of the extreme oligotroph ‘ Candidatus Pelagibacter ubique’ HTCC1062 on a defined medium

Abstract: Chemoheterotrophic marine bacteria of the SAR11 clade are Earth’s most abundant organisms. Following the first cultivation of a SAR11 bacterium, ‘Candidatus Pelagibacter ubique’ strain HTCC1062 (Ca. P. ubique) in 2002, unusual nutritional requirements were identified for reduced sulfur compounds and glycine or serine. These requirements were linked to genome streamlining resulting from selection for efficient resource utilization in nutrient-limited ocean habitats. Here we report the first successful cultivation of Ca. P. ubique on a defined artificial seawater medium (AMS1), and an additional requirement for pyruvate or pyruvate precursors. Optimal growth was observed with the collective addition of inorganic macro- and micronutrients, vitamins, methionine, glycine and pyruvate. Methionine served as the sole sulfur source but methionine and glycine were not sufficient to support growth. Optimal cell yields were obtained when the stoichiometry between glycine and pyruvate was 1:4, and incomplete cell division was observed in cultures starved for pyruvate. Glucose and oxaloacetate could fully replace pyruvate, but not acetate, taurine or a variety of tricarboxylic acid cycle intermediates. Moreover, both glycine betaine and serine could substitute for glycine. Interestingly, glycolate partially restored growth in the absence of glycine. We propose that this is the result of the use of glycolate, a product of phytoplankton metabolism, as both a carbon source for respiration and as a precursor to glycine. These findings are important because they provide support for the hypothesis that some micro-organisms are challenging to cultivate because of unusual nutrient requirements caused by streamlining selection and gene loss. Our findings also illustrate unusual metabolic rearrangements that adapt these cells to extreme oligotrophy, and underscore the challenge of reconstructing metabolism from genome sequences in organisms that have non-canonical metabolic pathways.

Light at Night Co‐distributes with Incident Breast but not Lung Cancer in the Female Population of Israel

Abstract: Recent studies of shift‐working women have reported that excessive exposure to light at night (LAN) may be a risk factor for breast cancer. However, no studies have yet attempted to examine the co‐...

Promoting Organizational Citizenship Behavior in Schools: The Impact of Individual and Organizational Characteristics

Abstract: Purpose:The success of schools fundamentally depends on teachers’ willingness to go above and beyond the call of duty, namely, to exhibit organizational citizenship behaviors (OCBs). Attempts to understand the causes of OCB frequently focus on individual characteristics; only recently have researchers begun to direct their attention to more contextual variables. The present study continues this line of research and proposes an integrative model. This allows the authors to examine simultaneously the relative impact of individual characteristics (dispositional variables of positive affectivity, negative affectivity, and teacher attitude) to perceived superior support and an organizational characteristic (of organizational values of individualism versus collectivism) on OCB at school.Method:Data were collected from a survey of 104 teachers and their principals at eight elementary schools in northern Israel.Results: A mixed models analysis demonstrates that perceived supervisor support and collectivism were p...
