养老建筑室内建筑环境的构建——以某市社会养老服务中心为例

养老地产在我国是一项新兴产业,作为该类建筑中的一个重要组成部分——供暖、通风与空气调节工程,其设计合理与否,对于居住环境和老年人身体健康的影响至关重要。设计人员为了力求打造一个更为适合老年人居住的建筑环境,结合具体工程,做了较为细致的探讨。文章对工程设计方案,包括采暖、空调方式,室内空气质量的控制,气流组织,工程材料选择,振动噪声控制,共五大方面,逐一作了介绍。     

恶劣环境对船舶焊接的影响

在船舶建造过程中焊接工作量约占全部的30%~40%,焊接是保证质量的重中之重。焊接质量出问题,就可能造成严重的后果。我厂沿江堤而建,空气中湿度大,工作条件差。密集性气孔很严重。所以,在这种情况下,对我厂焊接质量控制提出更高的要求。

Logics,Leaders, Lab Coats: A Multi‐Level Study on How Institutional Logics are Linked to Entrepreneurial Intentions in Academia

Situated in the context of academia, this study integrates ideas from institutional theory, person‐environment fit theory and leadership research to conceptualize and examine the cross‐level link between the organizational‐level institutional logic of research commercialization and the entrepreneurial intentions of researchers. Multi‐level analyses based on a sample of 254 researchers working for 85 research group leaders in 49 German research institutes reveal that two distinct attributes of research group leaders – that is, their track records of entrepreneurial behaviour and their entrepreneurial intentions – play a significant role in transmitting the organizational‐level logic to the individual level. We also observe a complementary interaction between organizational‐level commercialization logic and the entrepreneurial track records of leaders. We discuss how these findings advance our understanding of science commercialization through academic entrepreneurship and how they inform institutional theory and theory development in other domains of entrepreneurship research.     

制造业习性成本结构和经营安全程度分析

本文以制造业上市公司为研究对象,从收入动因成本中分解出收入动因固定成本和收入动因变动成本,进而计算出习性成本结构指标、保本点指标以及经营安全程度（安全边际率）指标。通过习性成本结构和经营安全程度分析可以得出以下研究结论：（1）以收入动因成本和营业净收入为基础进行的习性成本结构和经营安全程度分析是合理的、可靠的;（2）制造业整体上变动成本比重较高,行业整体营业净收入中变动成本比重为89.44%;（3）制造业整体经营风险较低,行业整体安全边际率为77.71%,处于“很安全”的范围。     

城市立交桥下空间的利用与设计

分析了立交桥下空间利用现状,针对桥下空间形态、桥墩形态的特征及功能利用取向,从公共性与适宜性结合、个性化与人性化结合、连续性与整体性结合、艺术性与生态性结合、安全性与适度性结合等六个方面,探讨了桥下空间的利用及设计原则。认为立交桥下的空间环境是一种宝贵的人工环境,应科学地利用这一环境,应从城市设计的角度对立交桥进行综合性的艺术设计。     

Dynamism and realignment in the HR architecture: Online labor platform ecosystems and the key role of contractors

Given the widespread contribution of independent contractors to organizational innovation and competitive advantage, it is timely to reassess assumptions about the HRM practices appropriate to their management and the rationale for organizations to work with them. In the original and highly influential HR architecture model of Lepak and Snell (1999), contractor status is viewed as an outcome of the low value and/or low uniqueness of human capital resulting in the proposition to externalize and manage them using either none or minimal compliance-based HRM practices. Developments in digital technologies and algorithmic management epitomized by online labor platforms prompt us to reconsider these assumptions and to challenge the proposed links between value/uniqueness of human capital, employment mode and HRM practices that are assumed by the HR architecture model. Using insights from online labor platforms, we argue that the significant benefits to firms of working with contractors, coupled with the possibilities offered by algorithmic management to efficiently monitor and regulate their behavior, provide a compelling reason for organizations to choose external employment modes even when workers are key to value creation. We challenge the alignment and stability of the relationships proposed by the HR architecture model, and offer propositions to extend the model by reconsidering the rationale for, and nature of, HRM practices associated with contractors. This reassessment is both timely and relevant given the growing prominence of business models where externalizing workers is central alongside the development of new forms of algorithmic human resource management to control them.     

VERTICAL GEOGRAPHIES,POLYVOCALITY AND THE EVERYDAY IN A DIVIDED CITY

The vertical turn in urban scholarship is a critique of the overly horizontal perspectives used in studying cities in academic research. This article broadens this scholarship by engaging with the ways that horizontal perspectives on urban conditions dominate not only scholarly perspectives but also professional responses to urban change. By drawing on research in the divided city of Mostar in Bosnia and Herzegovina, it argues for a ‘polyvocal’ approach to studying professional responses to urban conditions, one that facilitates a productive juxtaposition of those responses with city dwellers’ everyday engagements with the vertical qualities of the built environment. It also seeks to understand how vertical geographies—here, tall landmarks—in divided cities are seen as part of the complex urban realities of city dwellers in strategies of urban planning and heritage-making related to postwar reconciliation. These findings are compared with ethnographic data about how people make sense of tall landmarks in divided cities and how they experience and interpret them in relation to senses of togetherness and belonging to divided cities. By putting these two lines of research in a dialogue, the ‘polyvocal' approach offers a way to rethink conventional strategies of urban reconciliation and taken-for-granted ways of conceptualizing cities.     

CFO事务所经历与公司自愿信息披露——基于业绩预告的经验证据

CFO作为公司财务负责人,对公司盈余信息披露具有重要影响。基于业绩预告披露视角,以2006—2020年沪深A股上市公司为研究样本,探究CFO事务所经历对公司自愿信息披露的影响,研究发现,CFO有事务所经历的公司更倾向于自愿发布业绩预告并提高业绩预告精确度。并且,上述效应在CFO有“四大”会计师事务所经历时更为显著。横截面分析发现,当外部环境不确定性较高或公司信息环境较差时,CFO事务所经历更可能通过自愿发布精确度高的业绩预告来改善信息环境。业绩预告异质性分析表明,CFO有事务所经历的公司会发布更及时、高频和准确的盈余信息,从而提高业绩预告披露质量。
