Many studies have provided evidence that, in birds, inexperienced breeders have a lower probability of breeding successfully. This is often explained by lack of skills and knowledge, and sometimes late laying dates in the first breeding attempt. There is growing evidence that in many species with deferred reproduction, some prebreeders attend breeding places, acquire territories and form pairs. Several behavioural tactics assumed to be associated with territory acquisition have been described in different species. These tactics may influence the probability of recruiting in the breeding segment of the population, age of first breeding, and reproductive success in the first breeding attempt. Here we addressed the influence of behaviour ('squatting') during the prebreeding period on demographic parameters (survival and recruitment probability) in a long-lived colonial seabird species: the kittiwake. We also investigated the influence of behaviour on reproductive trajectory. Squatters have a higher survival and recruitment probability, and a higher probability of breeding successfully in the first breeding attempt in all age-classes where this category is represented. The influence of behaviour is mainly expressed in the first reproduction. However, there is a relationship between breeding success in the first occasion and subsequent occasions. The influence of breeding success in the first breeding attempt on the rest of the trajectory may indirectly reflect the influence of behaviour on breeding success in the first occasion. The shape of the reproductive trajectory is influenced by behaviour and age of first breeding. There is substantial individual variation from the mean reproductive trajectory, which is accounted for by heterogeneity in performance among individuals in the first attempt, but there is no evidence of individual heterogeneity in the rate of change over time in performance in subsequent breeding occasions  相似文献

Max Boholm 《Risk analysis》2019,39(6):1243-1261
In risk analysis and research, the concept of risk is often understood quantitatively. For example, risk is commonly defined as the probability of an unwanted event or as its probability multiplied by its consequences. This article addresses (1) to what extent and (2) how the noun risk is actually used quantitatively. Uses of the noun risk are analyzed in four linguistic corpora, both Swedish and English (mostly American English). In total, over 16,000 uses of the noun risk are studied in 14 random (n = 500) or complete samples (where n ranges from 173 to 5,144) of, for example, news and magazine articles, fiction, and websites of government agencies. In contrast to the widespread definition of risk as a quantity, a main finding is that the noun risk is mostly used nonquantitatively. Furthermore, when used quantitatively, the quantification is seldom numerical, instead relying on less precise expressions of quantification, such as high risk and increased risk. The relatively low frequency of quantification in a wide range of language material suggests a quantification bias in many areas of risk theory, that is, overestimation of the importance of quantification in defining the concept of risk. The findings are also discussed in relation to fuzzy‐trace theory. Findings of this study confirm, as suggested by fuzzy‐trace theory, that vague representations are prominent in quantification of risk. The application of the terminology of fuzzy‐trace theory for explaining the patterns of language use are discussed.  相似文献

How can an organization repair trust through communication after an ethical failure? This study examines how trust is repaired after an integrity-based trust violation using three different accounts: apology, excuse, and refusal. In our approach, we rely on two strands of attribution theory, which suggests that different attributions for responsibility and credibility affect trust. An experiment with n = 368 was conducted to explore trust repair effectiveness of apology versus refusal and apology versus excuse after an integrity-based trust violation. Results revealed apology as a double-edged sword; it repairs trust more successfully than refusal and excuse because it is evaluated as more credible. However, it is less successful than refusal and excuse because it is evaluated as more responsible.  相似文献

A driving force behind the establishment of a qualitative data archive in the United Kingdom has been the oral historian, Paul Thompson. He has complained that there is a ‘strange silence’ among qualitative sociologists on re‐analysis, and that many have been reluctant to deposit data. The first part of the paper suggests that the common ethical and practical objections can be overcome in establishing an archive in Australia. However, there is a more serious underlying ideological objection: that archiving promotes and institutionalises a narrow empiricist version of qualitative research. The rest of the paper makes this case by examining teaching materials on a British website, by reviewing Thompson's arguments, and by considering some examples of re‐analysis by sociologists. It is argued that qualitative researchers should respond critically, but that it is possible to address and overcome these problems when developing an Australian archive.  相似文献

This paper describes a strategy designed to catalyse a processof civic dialogue and social learning in an economically distressedsection of Virginia typically referred to as Southside or theDan River Region. The model underpinning this initiative employsthe arts and a grassroots leadership programme simultaneouslyto encourage a broad-scale civic conversation concerning thepast and potential future of the principal communities locatedin the Southside region. The combination of broad participationand development of an effective leadership cadre at the grassrootslevel should encourage the creation of robust community problemsolving coalitions across the region. The initiative aims toengender specific forms of locally driven community-based problem-solvingcoalitions: those that emphasize inclusiveness and value thefull participation of historically disenfranchised individuals.The project also employs non-traditional forums to promote creativedialogue and to encourage reflection among the broader citizenryon the significance and possible character of a new and regionalidentity.  相似文献

The aim of this article is to review existing goodness-of-fit tests for the exponential distribution under progressive Type-II censoring and to provide some new ideas and adjustments. In particular, we consider two-parameter exponentially distributed random variables and adapt the proposed test procedures to our scenario if necessary. Then, we compare their power by an extensive simulation study. Furthermore, we propose five new test procedures that provide reasonable alternatives to those already known.  相似文献

This article asks whether hymns written prior to and following the Second Vatican Council (Vatican II) differ significantly in their use of self- and divine-referential pronouns and answers this question by content analyzing the lyrics of 196 hymns in two different hymnals used in Catholic parishes today. It finds that hymns written post-Vatican II contain significantly more self-referential pronouns as well as an interestingly different mix of divine-referential pronouns than hymns written pre-Vatican II. These findings contribute to our knowledge of how shifts in religious organizations’ identities find expression in liturgical texts, which is important for understanding how the religious identities of individuals and communities are socially constructed over time.  相似文献

In New Zealand a simple pop-up message feature that provides gambling session information and forces a break in play is mandatory on all electronic gaming machines in all venues (EGMs). Previous research has demonstrated small effects of more sophisticated pop-up messages tested predominantly in laboratory environments. The present research examined gambler engagement with and views on the New Zealand pop-up messages and on the relationship between pop-up messages and EGM expenditure. A sample of gamblers was recruited at casino and non-casino (pub) EGM venues. Most participants were aware of pop-up messages (57 %) and many saw them often (38 %). Among gamblers who reported seeing pop-up messages, half read the message content, and a quarter believed that pop-up messages helped them control the amount of money they spend on gambling. Participants who reported being likely to stop gambling in response to pop-up messages spent significantly less money on gambling when variables that were independently associated with EGM expenditure were controlled for. A modest harm minimisation effect of the pop-up message feature that has been operating in New Zealand for 5 years was evident. Suggestions for improvement of the harm minimisation potential of the current pop-up message feature are discussed.  相似文献
