High population growth in the tropics is driving urbanisation, removing diverse natural ecosystems. This is causing native species to suffer while introduced synanthropes flourish. City planners are developing urban greenspace networks, in part trying to address this issue. Architects contribute to these greenspace networks by designing elevated and ground level green spaces on large-scale buildings. However, little evidence is available on whether building green spaces support native fauna. This is true for birds in tropical Singapore that support important ecosystem services and have existence value. Therefore, in this study, we conducted bird surveys and statistical analyses to determine, if and how vegetation on three building green space types (ground gardens, roof gardens and green walls) have a positive impact on native or introduced bird species. We found that elevated greenery (roof gardens and green walls) on large-scale buildings supported a higher richness of birds and abundance of urban native birds than control roofs and walls without vegetation. Ground gardens supported similar levels of native species as roof gardens but also a larger proportion of generalist synanthropes. However, we found no tropical forest habitat specialists across any space type. Therefore, we recommend roof gardens and ground gardens as a potential space for urban natives outside of a less competitive ground-level urban environment. Our study also found certain building design elements (height of elevated space, presence of specific plants) supported different species groups. Therefore, we suggest that these ecological requirements for different species groups are considered when designing a building’s green space.
Teenage parenting is a challenging venture—particularly when parenting while homeless. The present study explores in‐depth through case‐based analysis the lived experiences of three young homeless and parenting teens (one mother and two fathers). It is the first known study of teenage parenting and homelessness among Native Hawaiian youth, a key affected population. Interpretative phenomenological analysis of participants' individual interviews revealed three themes that characterize the experience of parenting as a teen while homeless: (a) They never raised me up (childhood experiences); (b) becoming mommy and daddy (early experiences of teen pregnancy and parenting while homeless); and (c) finding our place (current experiences of teen parenting and perspectives on teen pregnancy and homelessness). Implications for direct practice, social policy, and future research are discussed in the context of this complex reality. 相似文献
We present a theoretical model of Rabin’s famous calibration paradox that resolves confusions in the literature and that makes it possible to identify the causes of the paradox. Using suitable experimental stimuli, we show that the paradox truly violates expected utility and that it is caused by reference dependence. Rabin already showed that utility curvature alone cannot explain his paradox. We, more strongly, do not find any contribution of utility curvature to the explanation of the paradox. We find no contribution of probability weighting either. We conclude that Rabin’s paradox underscores the importance of reference dependence.

Contrary to the general belief, systemic risk does not only regard the risk posed by balance sheet relationships and interdependencies among institutions. It also features a temporal dimension related to the inappropriate responses of financial market participants to changes in risk over time. This paper proposes a method to simultaneously address the cross-sectional and the time dimension in which systemic risk materializes. The method is based on the TOPHITS algorithm. It provides three scores, namely borrowing, lending and time scores: the first two represent the systemic importance of the borrowing and the lending activity associated with each financial institution,while the third represents an empirical Early Warning Signal of the financial crisis. Our findings reveal that the identification of the time score as an indicator for an incoming market distress could be relevant to design macro prudential policies. 相似文献

We propose that the purposeful sharing of strategic decisions and the process of making and taking those between the dominant coalition of an organization (Strategic Shared Leadership or SSL thereafter), initiated and supported by a focal strategic leader or small team, engenders Organizational Dynamic Capabilities (ODCs) though the transfer of individually-residing DCs within the SSL team, the transformation -co-creation of novel ones and their embeddedness-institutionalization within the organization. It also enhances organizational cognition which mediates the relationship by enriching co-created ODCs and their capacity to deliver reliably change through sensing, seizing and reconfiguring. Accordingly, SSL serves as a co-creator and key predictor of the emergence of ODCs. This helps address the challenges of DCs to marry stability with change, be predictable and to be capable of predicting. 相似文献
Legal case histories are a basic and essential part of the law. It is proposed that evaluation case histories would be valuable to the evaluation profession in that they would serve both to accumulate knowledge and experience and as examples of how to do evaluations. Part I of the paper is a discussion of the nature, place and use of case histories in law. The format of a reported case, the use of cases by attorneys and how case decisions are reported and categorized are also discussed. Part II of the paper tries to envision the nature and use of evaluation case histories as a parallel to legal case histories. Matters discussed include the possible function and use of evaluation case histories, the difference between an evaluation report and an evaluation case history, information an evaluation case history could contain, and how case histories might be reported and categorized. 相似文献
