浅谈国内外生态建筑的发展状况

生态建筑作为建筑界积极迎接可持续发展挑战做出的选择,是建筑界为应对能源危机和生态危机所做出的积极回应。国外对生态建筑的理论研究和实践探索已经历了相当长的时间,取得了丰硕的成果;而生态建筑在我国由于种种原因尚在起步阶段。当前我国生态建筑的研究缺乏广泛的实践,生态建筑研究的经济合理性始终不能解决,生态建筑应当符合地方自然、社会、经济、资源条件等。     

Clinical characteristics and resource utilization of patients with bipolar disorder who have frequent psychiatric interventions

Abstract

Objective:

To compare the demographics, clinical characteristics and resource utilization of patients with bipolar disorder who required frequent psychiatric interventions (FPIs) with those needing fewer interventions in the Duke Healthcare System database between 1999 and 2005.

Methods:

This retrospective analysis was conducted using electronic medical records of bipolar patients with FPIs, defined as having ≥4 clinically significant events (CSEs) in any 12-month period while in the Duke University Healthcare System. CSEs were composed of emergency room visits, inpatient hospitalizations, or a change in psychotropic medication due to psychiatric symptoms (score ≥4 on the Clinical Global Impressions–Severity scale). Data were compared between patients with and without FPIs.

Results:

Of 632 patients with bipolar disorder 52.5% were identified as having FPIs. These patients were younger and more often female and African American than those with fewer interventions (p?<?0.01 for all). Patients with FPIs were generally prescribed more psychotropic and non-psychotropic medications, utilized more healthcare resources and experienced more psychiatric co-morbidities than those who did not require FPIs (p?<?0.01 for all).

Limitations:

These results are from a single healthcare system and may not be generalizable to all patients with bipolar disorder. This analysis was retrospective and relied on availability of adequate information recording and coding of diagnoses by physicians.

Conclusions:

Patients with bipolar disorder who required FPIs were significantly different from those with fewer clinically defined interventions with respect to their demographic and clinical characteristics and prescribed medications.     

Green multi-tier supply chain management: An enabler investigation

Stakeholder pressure, from actors including regulators, consumers and non-governmental organizations, has made organizations more responsible for poor environmental performance of their direct and sub-suppliers. Thus, green multi-tier supplier management (GMSM) has become an emergent topic. Yet it is still unclear how to enable GMSM practices effectively, i.e. how to enable sub-suppliers' environmental performance improvement. To help address the gap in the literature, this paper aims to identify enablers for sub-suppliers' environmental performance improvement, and it further applies a Decision-Making Trial and Evaluation Laboratory (DEMATEL)-based case study method to evaluate inter-relationships among these enablers and improve the focal company's GMSM practices, by using action research (AR) method principles. The data analysis and discussion with a follow-up evaluation after two years provided insights for the successful implementation of GMSM. The results show that top managers’ support from the organizations is a prominent and necessary foundational enabler. An interesting observation is that close proximity of supply chain members is regarded as a very prominent enabler. Evaluation and feedback on these enablers two years later found that the enabler mapping was beneficial, allowing them to address the most influential enablers, and thus the GMSM practices of the focal company has been highly improved. This paper concludes with directions for further research.     

Problematizing socioemotional wealth in family firms: a systems-theoretical reframing

The concept of socioemotional wealth (SEW) seeks to present an independent paradigmatic basis for family-firm research, and in doing so aims to establish a sound basis for the scientific legitimacy of family-firm research. Establishing that legitimacy requires scholars to demonstrate that SEW is based on coherent assumptions on several theoretical levels. This paper uses the problematization methodology to challenge the coherence of the theoretical assumptions underpinning SEW and to advance theory development. The results of this problematization show that SEW is built on a theoretical level close to the object of research (in-house assumptions), but that more deeply-rooted theoretical levels (e.g. paradigmatic assumptions) are not sufficiently elaborated. Moreover, the original conceptualization is based on a positivist-mechanistic view, which hinders SEW reflecting the complex reality of family firms. Based on the results of this problematization, new systems theory is applied to reframe SEW’s theoretical grounding. Thereby the main contribution of the paper is a critical reflection on the theoretical underpinnings of SEW (in particular root-metaphor and paradigmatic assumptions), serving as the basis for advancing a coherent theoretical understanding of this important concept in family business research.     

Supply chain risk analysis: a shipbuilding industry case

A lack of empirical studies on Supply Chain Risk Management (SCRM) is observed, especially in the industries of large projects. Therefore, this paper conducts a risk analysis on the Brazilian Shipbuilding Industry by generating an initial risk profile. A panel was conducted with executives from major shipyards, and the primary risks were identified, assessed, and evaluated. Findings corroborate the academic literature, reinforcing that companies recognise the importance of SCRM, but the concept is incipient and far from being successfully implemented in real life. Despite the fact that the shipyards identified important risks, the focus was on internal factors. Because the industry was exposed to risks from the external environment, no risk mitigation actions existed, resulting in the bankruptcy of many shipbuilders. This research is an initial step toward investigating SCRM techniques, offering academics a novel empirical approach that can serve as a systematic risk management tool for supply chain planning.     

Being Good Parents or Being Good Citizens: Dilemmas and Contradictions of Urban Families in Middle‐Class Enclaves and Mixed Neighbourhoods in Germany

In recent years, cities have become ever more attractive to middle‐class families. On the one hand, middle‐class families tend to withdraw into (often newly built) socially homogeneous middle‐class neighbourhoods. On the other hand, they are also known to move into inner‐city and socially mixed areas, thus triggering processes of gentrification. Academic literature has often denounced these housing choices as being either ‘separatist’ or ‘revanchist’, more broadly categorized as strategies of ‘middle‐class disaffiliation’. Although there is a grain of truth in these interpretations, the reality is certainly more complicated. In our research on middle‐class parents’ housing and neighbourhood choices as well as their patterns of neighbourhood use, carried out in each of the two types of residential area mentioned above, we have only very rarely found an explicit desire to draw boundaries that exclude those ‘beneath’ them. We rather argue that the housing choices and neighbourhood‐related activities of middle‐class family households are heavily influenced by the specific dilemmas the interviewees face as (working) urban parents. While a significant number of respondents worry about the social sustainability, justice and cohesion of urban society, they are also concerned about the future prospects of their children. Many find it difficult to reconcile these conflicting normative demands under the prevailing circumstances.     

Strategic Flexibility in New High‐Technology Ventures

Strategic flexibility is a vital capability for new ventures to update their strategies in a timely manner. However, the role of external knowledge sources in new ventures’ endeavours to develop strategic flexibility are unclear. Drawing on the knowledge‐based and relational views, we explore the effect of two sources of external knowledge: new product development (NPD) alliances, representing tightly coupled sources, and loosely coupled sources such as industry associations. Our field study of 148 high‐tech ventures found that the extent to which firms utilize knowledge from NPD alliances has a curvilinear relationship with strategic flexibility, whereas the extent to which firms utilize loosely coupled sources has a positive linear relationship with strategic flexibility. We also found that in new ventures, decentralization of decision‐making and institutional support enhance knowledge integration, positively moderating these relationships.
