Free/Libre Open Source Software (FLOSS) development teams provide an interesting and convenient setting for studying distributed work. We begin by answering perhaps the most basic question: what is the social structure of these teams? We conducted social network analyses of bug-fixing interactions from three repositories: Sourceforge, GNU Savannah and Apache Bugzilla. We find that some OSS teams are highly centralized, but contrary to expectation, others are not. Projects are mostly quite hierarchical on four measures of hierarchy, consistent with past research but contrary to the naive image of these projects. Furthermore, we find that the level of centralization is negatively correlated with project size, suggesting that larger projects become more modular, or possibly that becoming more modular is a key to growth. The paper makes a further methodological contribution by identifying appropriate analysis approaches for interaction data. We conclude by sketching directions for future research. 相似文献

The current study evaluated the benefits of free‐recall, cognitive load, and closed‐ended questions on children's (ages 6 to 11; N = 147) true and false eyewitness disclosures. Children witnessed an experimenter find a stranger's wallet and were then asked to make a false denial, false accusation, true denial, or true accusation regarding an alleged theft. Overall, the free‐recall question resulted in longer, more forthcoming and more detailed disclosures from older children and those who made a truthful accusation; however, children under the age of 9 and lie‐tellers mostly relied on the closed‐ended questions to discuss the theft. Although the cognitive load questions resulted in newly recalled information, there were no significant narrative differences between true and false statements on these questions. These findings suggest that forensic professionals should consider a child's developmental level, statement veracity, and disclosure‐type (denial vs. accusation) when examining the efficacy of these commonly used questioning strategies. 相似文献

Do egalitarians always express greater compassion toward the disadvantaged than toward the advantaged? A closer look at existing scholarship on the topic suggests that they likely do. Here, we investigated whether such tendency is also apparent within interdependent, high power distance cultures where the high‐status privilege prevails. Given the emphasis on harmony in social relations in interdependent cultures, we reasoned that egalitarians might experience a dissonance between their private equity values and a societal norm prescribing high‐status privilege, which we refer to as the value‐norm conflict. We therefore proposed and found evidence in Malaysia (N = 273) that egalitarians succumbed to the normative high‐status privilege in their culture: They displayed greater compassion towards higher than lower status victims, but only when the political cost of doing so was low. Interestingly, anti‐egalitarians displayed equitable levels of compassion for high‐ and low‐status victims, but only when the political cost for taking such action also was low. Hence, we show that even egalitarians can, at times, favor the privileged and that anti‐egalitarians can act equitably, so long as the political cost of doing so is trivial for them. 相似文献

Data documenting poor understanding among research participants and real-time efforts to assess comprehension in large-scale studies are focusing new attention on informed consent comprehension. Within the context of biobanking consent, we previously convened a multidisciplinary panel to reach consensus about what information must be understood for a prospective participant’s consent to be considered valid. Subsequently, we presented them with data from another study showing that many U.S. adults would fail to comprehend the information the panel had deemed essential. When asked to evaluate the importance of the information again, panelists’ opinions shifted dramatically in the direction of requiring that less information be understood. Follow-up interviews indicated significant uncertainty about defining a threshold of understanding and what should happen when prospective participants are unable to grasp key information. These findings have important implications for urgently needed discussion of whether consent comprehension is an ethical requirement or an ethical aspiration. 相似文献

This study compared the Stepwise Interview, Cognitive Interview, and Reality Interview in detecting deception with inmates. The dependent measures were the amount of unique details provided during the free narrative and mnemonics and the number of words provided during the free narrative and mnemonics of each interview. The Stepwise Interview generated 58.3% accuracy, the Cognitive Interview generated 70.0% accuracy, and the Reality Interview generated 93.3% accuracy. The different tasks of these interviews increased the differences between honest and deceptive statements and therefore, increased the accuracy in detection of deception. Differential recall enhancement is used to explain the findings. 相似文献

Cognitive behavior therapy (CBT) is an effective treatment for obsessive-compulsive disorder (OCD). However, less is known about how obsessions and compulsions change during treatment, either in tandem, sequentially, or independently. The current study used latent difference score analysis to show path-analytic dynamic modeling of OCD symptom change during CBT. Four competing models of the temporal relationship between obsessions and compulsions were examined: no coupling (obsessions and compulsions are not dynamically related), goal directed (obsessions lead to subsequent changes in compulsions), habit driven (compulsions lead to subsequent changes in obsessions), and reciprocal. Treatment seeking participants (N = 84) with a principal diagnosis of OCD completed 12 weeks of CBT group therapy and completed measures assessing obsession and compulsion severity at pretreatment, Sessions 4 and 8, and end of treatment. Bivariate results supported the goal directed traditional CBT model, where obsession scores are temporally associated with subsequent changes in compulsion scores. These results have implications for theoretical and treatment modelling of obsessions and compulsions in OCD treatment. 相似文献

Information obtained via direct observation of children's sleep disturbance throughout the night in their home can guide the assessment and treatment process, but watching live or via recorded video might be impractical in terms of time expenditures. In Experiment 1, we assessed the accuracy and reliability of a motion‐detection camera with human motor movements. In Experiment 2, we tested the system's generality by using it to obtain in‐home measures of sleep disturbance for three children with autism spectrum disorder and compared the accuracy to a continuous measurement system. We also measured scoring efficiency and assessed parents' acceptability of the camera. Results provide preliminary support for motion detection in measuring sleep disturbance, but further evaluation of motion detection to improve accuracy is warranted. 相似文献

Technological advances have allowed professionals to obtain extended recordings of caregiver–client interactions in natural settings, but scoring recorded video at normal speed to identify instances of low‐rate problem behavior is impractical in terms of scoring time. Fast forwarding is a continuous measurement system in which all seconds of an observation are viewed at a speed faster than normal. In Study 1, we evaluated whether three groups of five observers could discriminate problem behavior at three fast‐forwarding speeds across 10‐min observations. We analyzed the efficiency of using fast forwarding compared to continuous scoring, and interobserver agreement across the fast‐forwarding speeds. In Study 2, we compared the accuracy, efficiency, and social acceptability of fast forwarding (3.5x) and momentary time sampling (3.5 s) across 90‐min observations. Results support the use of 3.5x fast forwarding as a viable measurement system of improving the practicality of scoring problem behavior from video. 相似文献

This study examined the effects of goal difficulty, negative affectivity (NA), and positive affectivity (PA) on performance and task attitudes on a complex task. Research participants played an air traffic controller (ATC) simulation and were assigned either an easy or difficult goal at 2 different points in time: early during skill acquisition, and after several experimental trials. We hypothesized that the effect of difficult goals would vary depending on whether they were administered early and late during skill acquisition. We also hypothesized that NA and PA would moderate the effect of goal difficulty. Neither the early nor late goal assignments related to performance or task attitudes as hypothesized. Instead, PA and NA both moderated goal‐outcome relationships. 相似文献
