This article describes the characteristics of innovative organizations as perceived by employees of nonprofit and government organizations in three quite different countries, South Korea, China, and Argentina. A total of 44 employees participated in the studies (13 from South Korea; 16 from China; and 13 from Argentina). At the first stage of the study they were asked to free list characteristics of innovative organizations. At the second stage of the study, country‐specific measures containing characteristics of innovative organizations were created, and participants were asked to rate each characteristic on a Likert scale (1 = not characteristic at all of an innovative organization; 5 = extremely characteristic of an innovative organization). This task produced ratings of perceived characteristics of innovative organizations for each country. Cultural consensus analysis widely used in the field of cognitive anthropology was employed next to assess the degree of agreement among the participants on what consistutes an innovative organization. Among the common perceived characteristics of innovative organizations were participation in decision making, teamwork, responsiveness to emerging client and societal needs, adaptability, employee support and value, and accepting failure. While the characteristics produced through the free listing technique showed a lot of similarities, the importance of those characteristics was rated quite differently across the three samples.  相似文献

To understand social issues and practices such as those related to climate change and technological change that are clearly future-oriented – collectively experienced events that are “not yet” – and co-constructed by different actors, we need nuanced conceptualizations of how people think about, negotiate and co-create futures that allow us to understand not only what people (can) think and do about future-related issues but also how that happens, what for and with which implications. However, so far, one of the key theoretical approaches that has conceptualised how people make meaning in situations of change and uncertainty – the socio-psychological social representations theory (SRT) – has not often engaged with the future or with different forms of temporality. By contrast, the French pragmatic sociology of engagements and critique (PS) has engaged with these notions, conceptualising them in relation to materiality and a plurality of moral orientations – two dimensions often seen as key to how collective futures are made and imagined. To offer a more nuanced and systematic conceptualization of how people represent the future and with what consequences, this paper will present, compare and synthesise SRT and PS, as a first step towards an interdisciplinary research agenda on social change and representations of the future.  相似文献

In many medical studies, there are covariates that change their values over time and their analysis is most often modeled using the Cox regression model. However, many of these time-dependent covariates can be expressed as an intermediate event, which can be modeled using a multi-state model. Using the relationship of time-dependent (discrete) covariates and multi-state models, we compare (via simulation studies) the Cox model with time-dependent covariates with the most frequently used multi-state regression models. This article also details the procedures for generating survival data arising from all approaches, including the Cox model with time-dependent covariates.  相似文献

The present study overcomes the limited empirical evidence on the association between well-being and school engagement in times of adversity by exploiting available data from two large and comparable samples of eighth graders; one obtained prior to the COVID-19 pandemic and the second obtained during the pandemic. Results suggest that adolescents were less engaged with their learning context during the pandemic, as well as lower in positive and negative affect, but slightly more satisfied with life. Through SEM we found a stronger positive association between positive affect and school engagement in the COVID-19 group compared with the pre-COVID-19 group. This finding highlights the important role of positive affect in supporting better academic functioning in the aftermath of a global crisis.  相似文献

The international standard ISO 9612:2009, regarding the determination of occupational noise exposure through an engineering method, establishes a methodology for evaluating the exposure of workers to occupational noise, through the specification of three different strategies, namely: task-based measurement (TBM); job-based measurement (JBM) and; full day measurement (FDM). In this work, questions are raised, "resulting in a literature review regarding the need to test the functionality of the three strategies, through the systematic comparison between them and analysis of their application impact at several levels. There is a need to test the compare these three strategies, since there are no peer-review studies in this domain. In fact, there are still no studies that systematically do the comparison between them and analyze the impact of their application at various levels, such as the precision and accuracy of the results, the required equipment, time spent and, most important, the estimation of the uncertainty associated to the measurements.  相似文献

The DSM-5 was published in 2013 and it included two substantive revisions for gambling disorder (GD). These changes are the reduction in the threshold from five to four criteria and elimination of the illegal activities criterion. The purpose of this study was to twofold. First, to assess the reliability, validity and classification accuracy of the DSM-5 diagnostic criteria for GD. Second, to compare the DSM-5–DSM-IV on reliability, validity, and classification accuracy, including an examination of the effect of the elimination of the illegal acts criterion on diagnostic accuracy. To compare DSM-5 and DSM-IV, eight datasets from three different countries (Canada, USA, and Spain; total N = 3247) were used. All datasets were based on similar research methods. Participants were recruited from outpatient gambling treatment services to represent the group with a GD and from the community to represent the group without a GD. All participants were administered a standardized measure of diagnostic criteria. The DSM-5 yielded satisfactory reliability, validity and classification accuracy. In comparing the DSM-5 to the DSM-IV, most comparisons of reliability, validity and classification accuracy showed more similarities than differences. There was evidence of modest improvements in classification accuracy for DSM-5 over DSM-IV, particularly in reduction of false negative errors. This reduction in false negative errors was largely a function of lowering the cut score from five to four and this revision is an improvement over DSM-IV. From a statistical standpoint, eliminating the illegal acts criterion did not make a significant impact on diagnostic accuracy. From a clinical standpoint, illegal acts can still be addressed in the context of the DSM-5 criterion of lying to others.  相似文献

We consider a stochastic logistic growth model with a predation term, and a diffusive stochastic part with a power-type coefficient. We provide criteria for the persistence of the population and for the existence and uniqueness of a stationary measure. Furthermore, we perform a detailed study of the densities of the stationary measures resorting to the forward Kolmogorov equation. We compile our results in a stochastic bifurcation diagram, drawing comparisons with the corresponding deterministic model.  相似文献

The present research evaluates people’s perception of serial murders, analysing the effects of controllability in counterfactual reasoning about the past and the future, as well as attributions of responsibility and blame. Besides, the research analyses the effects of perspective (one’s own versus other people’s) in these attributions. Participants were 442 students who answered open-ended questions designed for this study. The first experiment shows that people focus on controllable factors previous to these events. When considering the avoidance and prevention of general serial murders, they focus on representatives of formal authority. Moreover, when judging from their own perspective, blame is attributed to the perpetrator and responsibility to both parties; while from another person´s perspective, they attribute feelings of either responsibility or guilt to the representatives of formal authority and a lack of these feelings to the perpetrator. The second experiment shows identical results regarding the specific case of a well-known serial killer in England and Spain. These findings demonstrate that this perception has implications for the legal framework and the prevention of violent crimes.  相似文献
