Indoor Climate and Thermal Comfort from a Long-Term Perspective

ABSTRACT

This article discusses how a Swedish wooden burgher house, the mid-1660s Burmeister House, was adapted over the course of 250 years to satisfy ever-changing expectations of thermal comfort. The investigation is based on the climatic conditions of the Nordic Region, where the issue of thermal comfort is crucial when attempting to understand the development of indoor environments. The article explores how spatiality, heating, and interior decor and furnishing operated and affected the inhabitants' experiences of indoor climate and thermal comfort. The results show that Burmeister House followed a general pattern of improvement, especially with regard to innovations in heating. Burmeister House ceased to be a private residence when it was restored and turned into a historic house museum. Rather than revealing its history, restorations carried out in the twentieth century worked to conceal or remove most of the building's more recent history. As a consequence, the house has become more difficult to use since it can no longer be efficiently heated.     

On an application of the diffusion approximation of the generalized birth and death process for stochastic population projection

Assuming that both birth and death rates are density and time dependent, a diffusion approximation of the generalized birth and death process has been considered in this paper to obtain a suitable stochastic population model describing the population size and its moments. A simple method of estimating the parameters of the model Is discussed. The predictions of the expected size of the population, and the variance are made and compared with the corresponding census figures as well as with another deterministic projection series made for the corresponding period.     

Organizational climate and burnout in a New Zealand social service agency

Abstract

A two-phase study was conducted on the relationship between organizational climate variables and burnout among personnel in a multifunction community service agency. Initial interviews with a small pilot sample identified major sources of stress, which were then incorporated into a second-phase questionnaire to all staff. Multiple regression analyses illustrated that perceived interactions between head office administrators and sections of the agency contributed significantly to emotional exhaustion, whereas perceptions of within-section interactions and involvement in decision-making had a positive impact on personal accomplishment. Perceived communication levels, however, were negatively related to personal accomplishment. The findings suggest the importance of organizational variables and highlight strategies for burnout reduction and effective stress management in human service organizations.     

投影CRT用磁聚焦电子枪

论述了一种成功运用于１２２ｃｍ背投式彩色投影电视机阴极射线管（ＣＲＴ）中的磁聚焦电子枪。该枪采用了预聚焦发射系统和磁聚焦主透镜构成的双聚焦系统。经测试发现，当阴极电流为０．５～１．０ｍＡ时，其上屏束斑直径仅为０．０６５～０．０８０ｍｍ。     

Cayley-Klein模型在研究罗氏平面直线中的应用

由于平行公理不同，导致罗氏平面直线与欧氏平面直线有很大差异。本文利用Cayley-Klein模型探讨罗氏平面直线的特性。     

科技英语文体中的类比与隐喻

类比和隐喻是认知语言学中常见的两种语义建构机制,其最终目的是降低认知难度,因此经常被运用在以阐释为目的的科技英语文体中。两者常因映射机制的相似性而被混淆。然而,从结构映射及概念隐喻理论可以看出,类比侧重系统结构的映射对接,而隐喻侧重概念特征单向投射。即使显性或隐性地共同呈现出“A is B”的语言结构,在具体语境中也有类比或隐喻的侧重性,而非完全雷同,但在某些语境下又可能存在相互补充的糅合关系。     

冲动性购买情境下消费者后悔影响的实证研究

采用情境投射与普通问卷相结合的多样化研究方法,探讨冲动性购买负面后果的影响以及不同归因的消费者受影响程度是否不同。结果表明,如果第一次冲动性购买行为带来负面后果,再次遇到类似情境时消费者的购买冲动性和认知评价都会受到较大影响,他们往往降低自身的购买冲动性,倾向于不再购买,并且对下一次购买具有负面的认知评价。同时,不同归因的消费者对再次冲动性购买的认知评价存在差异。     

投射偏差视角下的服务类品牌消费--以农村信息消费支付意愿为例

现将投射偏差模型框架引入服务类耐用品消费者均衡中,从理论上阐述投射偏差如何会导致消费者在服务类商品消费时无法达到效用最大化。研究采用实验和实地调研的方法,一共有251名人员参与了实验与调研,分析上网体验对于未来一年宽带的支付意愿影响。研究结果发现,人们在体验上网前后对于信息的认知状态有显著差异,没有上过网的人会基于当前的认知状态而低估未来一年宽带的效用,其支付意愿明显低于上过网的人,投射偏差在服务类耐用品的消费均衡中发挥了重要作用。     

Minority government and marginal members: new issues for political and policy legitimacy in Australia

A steady decline in major party support in Commonwealth nations has resulted in changing parliamentary compositions, including the growing prevalence of minority government. Such situations pose new questions for notions of government legitimacy within Westminster systems. For instance, is negotiation with cross-benchers an example of government illegitimacy? What is the legitimate role of non-ministerial members when the composition of parliament gives them the final say on the enabling legislation for public policy? What is the legitimate response of the public sector regarding policy-making in the context of minority government? In this paper, we reflect on how a ‘marginal member’ concept can provide new insights into such issues and their implications.
