Urban areas are increasing in number, extent, and human population density worldwide. There is potential to mitigate negative impacts of urbanization to native pond-breeding amphibians by providing habitat in both remnant natural and constructed wetlands. This study examines amphibian use of potential breeding sites in natural and constructed ponds in a large metropolitan area to investigate habitat characteristics that are associated with successful breeding. I surveyed 62 ponds over three breeding seasons in Portland, Oregon, measuring eleven habitat characteristics that may influence their successful breeding: pond depth, nitrate level, aquatic refugia, aquatic vegetation, surrounding vegetation, pond permanence, presence of fish and of introduced bullfrogs, surrounding road density and forest cover, and whether they were constructed or remnant natural ponds. Five of the six native pond-breeding species that occur in the region were regularly found breeding in city ponds. Surrounding forest cover and amount of aquatic vegetation were highly associated with breeding, indicating that preserving and planting vegetation likely benefits urban amphibians. Non-native bullfrogs were not associated with native species richness. Surprisingly, whether a pond was natural or constructed was also only weakly associated with native species breeding, and the trend was towards higher presence for all species in constructed ponds. This indicates that novel, human-dominated areas can provide habitat for these species. Consideration of habitat characteristics associated with breeding success in urban pond management will likely benefit native amphibians in these rapidly expanding landscapes. 相似文献

Evidence suggests that parenting is associated cross‐generationally and that children's genes may elicit specific parenting styles (evocative gene‐environment correlation). This study examined whether the effect of children's genotype, specifically 5‐HTTLPR, on mothers' parenting behaviors was moderated by her own parenting experiences from her mother. Two independent samples of three‐year‐olds (N = 476 and 405) were genotyped for the serotonin transporter gene, and observational measures of parenting were collected. Mothers completed measures of the parenting they received as children. The child having a short allele on 5‐HTTLPR was associated with more maternal hostility (Samples 1 and 2) and with less maternal support (Sample 1), but only if the mother reported lower quality grandmothers' parenting (abuse and indifference in Sample 1 and lower levels of grandmother care in Sample 2). Results support the possibility of a moderated evocative gene‐environment correlation. 相似文献

The ongoing COVID‐19 pandemic is having a profound impact on organizations across the world, as businesses and societies face their greatest challenges for many decades. Over the past 20 years, the International Journal of Management Reviews (IJMR) has published many reviews of research that bring together the key findings across important bodies of research relevant to understanding how organizations might confront grand challenges such as these. Reflecting on this work, we have chosen a number of recent reviews published in the journal which have relevance both for practitioners and scholars in the current crisis. We invited the authors of these papers to offer some comments, which we have drawn from in the discussion below. 相似文献

Police court columns were a popular and flourishing representation of the courtroom in the early nineteenth-century British and Irish press. Despite this, they have been little used by historians, perhaps due to their often humorous and comic depictions of the courtroom. This article re-evaluates the Irish police court columns as a site of debate around Irish national identity at the beginning of the nineteenth century. It argues that these representations were not only sophisticated, but allowed the Irish to reformulate the stereotype of the stage Irishman. Moreover, as representations that captured behaviours of individuals within the courtroom, they provided an opportunity for a broad swathe of the community to engage in broader debates around the nature of Irishness and Irish political rights. 相似文献

What are the minimal requirements of rational choice? Arguments from the sequential-decision setting
Katie Siobhan Steele 《Theory and Decision》2010,68(4):463-487
There are at least two plausible generalisations of subjective expected utility (SEU) theory: cumulative prospect theory (which
relaxes the independence axiom) and Levi’s decision theory (which relaxes at least ordering). These theories call for a re-assessment
of the minimal requirements of rational choice. Here, I consider how an analysis of sequential decision making contributes
to this assessment. I criticise Hammond’s (Economica 44(176):337–350, 1977; Econ Philos 4:292–297, 1988a; Risk, decision and
rationality, 1988b; Theory Decis 25:25–78, 1988c) ‘consequentialist’ argument for the SEU preference axioms, but go on to
formulate a related diachronic-Dutch-book-style’ argument that better achieves Hammond’s aims. Some deny the importance of
Dutch-book sure losses, however, in which case, Seidenfeld’s (Econ Philos 4:267–290, 1988a) argument that distinguishes between
theories that relax independence and those that relax ordering is relevant. I unravel Seidenfeld’s argument in light of the
various criticisms of it and show that the crux of the argument is somewhat different and much more persuasive than what others
have taken it to be; the critical issue is the modelling of future choices between ‘indifferent’ decision-tree branches in
the sequential setting. Finally, I consider how Seidenfeld’s conclusions might nonetheless be resisted. 相似文献

Membership‐based associations are critical to their local communities and the overall social impact of the nonprofit sector. This study examines how organizational social responsibility within nonprofit membership associations influences positive member involvement behaviors, including volunteering, speaking positively about the club, and member loyalty. Self‐administered online questionnaires were completed by 735 members within seven grassroots membership associations in Ontario, Canada offering community‐based sport programs. Results show that members are somewhat aware of and felt positively about their organization's socially responsible efforts. Awareness of these efforts had a positive direct effect on the involvement behaviors of members, including intention to stay involved with their club and speaking positively about their club to others (i.e., word of mouth). Members' level of social consciousness was found to have a positive direct effect on word of mouth. Furthermore, members' positive evaluation of sport clubs' socially responsible initiatives was found to partially mediate the positive relationship between social consciousness and involvement behavior, as well as partially mediate the positive relationship between awareness of those efforts and involvement behavior. Results of this research provide grassroots membership associations with an in‐depth understanding of how their organization's efforts toward social responsibility influence member perceptions and behaviors, which may help them focus their efforts and more effectively manage their social change agenda moving forward. 相似文献

Recent evidence suggests that during the first year of life, a preference for consonant information during lexical processing (consonant bias) emerges, at least for some languages like French. Our study investigated the factors involved in this emergence as well as the developmental consequences for variation in consonant bias emergence. In a series of experiments, we measured 5‐, 8‐, and 11‐month‐old French‐learning infants orientation times to a consonant or vowel mispronunciation of their own name, which is one of the few word forms familiar to infants at this young age. Both 5‐ and 8‐month‐olds oriented longer to vowel mispronunciations, but 11‐month‐olds showed a different pattern, initially orienting longer to consonant mispronunciations. We interpret these results as further evidence of an initial vowel bias, with consonant bias emergence by 11 months. Neither acoustic‐phonetic nor lexical factors predicted preferences in 8‐ and 11‐month‐olds. Finally, counter to our predictions, a vowel bias at the time of test for 11‐month‐olds was related to later productive vocabulary outcomes. 相似文献

Parent–child discussions about emotion are a key socialization influence on children’s socio‐emotional development. Extant research on parent–child discussions about emotion largely focuses on three main types of discourse content: parental elaboration, parental use of emotion labels and explanations, and parental emotion coaching. A new direction involves distinguishing between parents’ direct and indirect communication of discourse content. This distinction may be vital when considering the role of children’s communicative competence in their developing socio‐emotional competence. We integrate literature on (in)direct communication, a concept prominent in linguistics, and emotion socialization. We argue that parental indirect communication can teach children communicative competence in the context of emotion talk. We discuss literature from the developmental and linguistic fields on parents’ teaching of communicative skills, as well as potential cognitive, relational, and emotional functions of indirectness, with communication and its socialization embedded within cultural context. Finally, we suggest new research directions examining the role of parental indirect communication in children’s socio‐emotional development. By integrating developmental and linguistic literatures, we provide a novel approach to the study of parental emotion socialization through parent–child discourse. 相似文献

This article describes research undertaken in 2018 in a therapeutic residential home for young women with multiple and complex needs in out-of-home care in England. Based on qualitative interviews with five young women, aged 16–18, and four professionals working with the home, the article analyses the under-researched leaving care needs and experiences of this group of young women. The findings highlight the tensions between notions of childhood and expectations of adulthood surrounding this group of young people. These converge around reaching the age of 18 and foreground vulnerability on the one side, and responsibility on the other. 相似文献
