CCM构件实现框架的分析与研究

CCM构件实现框架(CIF）为构造构件实现定义了的编程模型。作为编程抽象，CIF不但能与现存POA框架兼容，而且还能使编程人员与它的复杂性隔离。CIF使用CIDL描述创建编程框架自动化构件的基本行为。该文对CIF的架构和语义进行了剖析，描述了CCM构件的实现，然后CIF内部元素的关系进行了研究。     

“It’s Just a Matter of Adjustment”: Residents’ Perceptions and the Potential for Low-impact Home Practices

In addition to material, spatial and thermal standards and norms that influence the resource intensity of home environments, a key indicator of the environmental impact related to housing is found in residents’ ways of life. Of interest to the study presented in this paper is how residents’ perceptions of home and living standards relate to opinions on environmental issues and the reduction of resource use, exploring the potential and willingness to engage in low-impact ways of living. Empirical material from a questionnaire (n = 156) and interview study (n = 22) with residents in a tenant-owned housing association in Sweden provides insights into conventions and perceptions surrounding practices primarily linked to voluntary simplicity, living smaller as well as sharing spaces and resources. The study emphasizes the need for understanding residents’ perspectives and the implications this might have for targeting the resource intensity of homes in future development and policy.     

Work-related musculoskeletal disorders in home care nurses: Study of the main risk factors

BackgroundNurses are a risk group for work-related musculoskeletal disorders (WMSDs). Several studies reveal that nurses have high prevalence rates of injuries and symptoms related to WMSDs. However, many of these studies focus mostly on hospital nurses. Worldwide, few studies include home care nurses.ObjectiveThis work aimed to identify the body region most affected by musculoskeletal complaints in home care nursing, and subsequently develop a statistical model, that includes the main risk factors, to predict the risk of having musculoskeletal complaints in the identified region.MethodsThe research method was based on the Standardised Nordic Questionnaire applied to home care nurses working at Health Centres of northern Portugal. Univariate and multivariate models of logistic regression were used to meet the goals of this work.ResultsHome care nurses have a three times greater chance of having lumbar complaints than their counterparts working only at Health Centres (OR = 3.19 (p < 0.05), with a 95% confidence interval [1.256; 8.076]). A statistical model with seven variables (forearm posture; static postures; arm posture; arm supported; bed height; job satisfaction; assistive devices) was obtained to predict lumbar complaints.ConclusionsThe lumbar region was identified as the most affected by musculoskeletal complaints. These complaints were associated with seven factors.     

The impact of government subsidies and enterprises’ R&D investment: A panel data study from renewable energy in China

In this research, we aim to understand the influence of government subsidies on enterprises’ research and development (R&D) investment behavior, particularly in China’s renewable energy sector. We are also interested in examining how the attributes of enterprise ownership act as a moderating variable for the relationship between government subsidies and R&D investment behavior. Three classical panel data analysis models including the pooled ordinary least squares (OLS) model, the fixed effect model and the random effect model are employed. We find that government subsidies have a significant crowding out influence on enterprises’ R&D investment behavior and that the influence is further moderated by the attributes of enterprise ownership. Moreover, a panel threshold regression model is used to demonstrate how the influence of government subsidies on enterprises’ R&D investment behavior will change when government subsidies increase. Two thresholds, 0.6% and 10.1%, are identified. We recommend that relevant government departments should motivate enterprise R&D investment behavioral intention by increasing subsidies within a certain range. Different attributes of enterprise ownership should also be considered as part of policy reform and re-structuring relating to government subsidies.     

Design and validation of a motion-tracking system for ROM measurements in home rehabilitation

This work deals with the design, implementation and experimental validation of a home rehabilitation system capable of bringing a real-time 3D reconstruction of human posture to the therapist’s desk. The system has been validated against two commercial systems, capable of providing joint angle measurements and commonly used in rehabilitation gyms, which are used profitably to assist clinics in limb motor dysfunction treatment. Early experimental results promise to provide measurements accurate enough to complement the subjective therapist’s perception with objective observations, leading to quantitative evaluation.     

China’s electric vehicle subsidy scheme: Rationale and impacts

To promote the market penetration of electric vehicles (EV), China launched the Electric Vehicle Subsidy Scheme (EVSS) in Jan 2009, followed by an update in Sep 2013, which we named phase I and phase II EVSS, respectively. In this paper, we presented the rationale of China’s two-phase EVSS and estimated their impacts on EV market penetration, with a focus on the ownership cost analysis of battery electric passenger vehicles (BEPV). Based on the ownership cost comparison of five defining BEPV models and their counterpart conventional passenger vehicle (CPV) models, we concluded that in the short term, especially before 2015, China’s EVSS is very necessary for BEPVs to be cost competitive compared with CPVs. The transition from phase I to phase II EVSS will generally reduce subsidy intensity, thus resulting in temporary rise of BEPV ownership cost. However, with the decrease of BEPV manufacturing cost, the ownership cost of BEPV is projected to decrease despite of the phase-out mechanism under phase II EVSS. In the mid term of around 2015–2020, BEPV could become less or not reliant on subsidy to maintain cost competitiveness. However, given the performance disadvantages of BEPV, especially the limited electric range, China’s current EVSS is not sufficient for the BEPV market to take off. Technology improvement associated with battery cost reduction has to play an essential role in starting up China’s BEPV market.     

(Re)conceptualising the boundaries between home and homelessness: the unheimlich

A burgeoning cross-disciplinary literature signifies a move towards diversifying understandings of the meanings of ‘home’. Homelessness is inextricably bound up in these definitions. While earlier work has considered meanings of homelessness, attempts to advance understandings of the relationship between home and homelessness have been sporadic. This article attempts to reinvigorate discussion around the home–homelessness relationship by problematizing the binaries in current understandings and poses a different way of theorizing the interplay between the two concepts. Drawing on interviews with women accessing homelessness services in the North of England, discussion interweaves women’s meanings of home and homelessness with the Freudian notion of the ‘unheimlich’. The ‘unheimlich’ captures the uncanny process of inversion whereby the familiar domestic sphere of the house turns into a frightening place; and a typical space of homelessness—the hostel—is considered home. The article seeks to contribute more adequate theoretical tools for future research to better understand and articulate the complexities of home and homelessness.

Electric vehicle technology in China: An exploratory patent analysis

Currently, the electric vehicle (EV) technology is of great interest in China and around the world. This paper first conducts a comprehensive review of China's EV policies and the development of China's EV technology, and then analyzes the domestic performances of China's EV technology and its international competitiveness by adopting the recently developed concept of transnational patents. The results show an outstanding performance for China's EV technology in the domestic market, but a relatively poor performance in the international markets. Finally, several main factors causing the inconsistent performance of China's EV technology are proposed and discussed.
