Technological innovations have been investigated by means of substitution and diffusion as well as evolution models, each of them dealing with different aspects of the innovation problem. In this paper we follow the well known research traditions on self-organisation models of complex systems. For the first time in the literature we show the existence of a specific niche effect, which may occur in the first stage of establishment of a new technology. Using a stochastic Master equation approach, we obtain analytical expressions for the survival probabilities of a new technology in smaller or larger ensembles. As a main result we demonstrate how a hyperselection situation might be removed in a stochastic picture and thresholds against the prevailing of a new technology in a step-by-step process can be overcome. 相似文献

To what degree has the development of alternative mortgage funding channels promoted the recent boom and bust in U.S. housing markets? Past research examined whether Alt‐A and subprime market shares are correlated with the housing bubble. This article expands the analysis to include the share of specific “alternative” lending terms and finds that the shares of interest‐only and negative amortization loans are important factors in explaining the housing bubble. This result suggests that research on the housing market bubble should focus on the impacts of loan contract terms rather than loan channel. 相似文献

Residents’ views are pertinent in urban-park design and management, yet they are often ignored. Social-empirical studies could enhance socially relevant park design. As a compact city, Hong Kong's limited greenspaces are often too small, surrounded by incompatible activities, and fail to meet user demands and expectations. This study explores the response of citizens living in the crowded urban milieu to inadequate greenspace provision. A questionnaire survey gleaned opinion from residents in representative residential neighbourhoods in old city and new towns. Green sites are appreciated more for pragmatic microclimatic and amenity benefits than social and high-order environmental functions. The principal limitations are deficiency in sports facilities and greenery. Respondents favour more trees, dispersed seating design and large parks. The preferences are mainly related to age, income, education and retirement status. The high-density living milieu may have weakened attitude and perception towards urban nature. The findings could inform public policies and programmes on urban parks. They call for an institutional restructuring to facilitate active public engagement in greenspace planning and management. 相似文献

AbstractGlobalization has led to an increase in international mobility in many occupational fields. Therefore, scholars from a variety of disciplines have studied the topic of skilled migration. The purpose of this study is to review and synthesize the empirical research on skilled migrants’ qualification-matched employment across multiple disciplines. Skilled migrants are people on the move who possess university degrees or extensive work experience in professional fields when they leave their countries of origin to seek employment elsewhere. This review synthesizes findings of 106 empirical studies published from 1990 to mid-2017 on skilled migrants’ employment. We develop a conceptual model that includes antecedent conditions associated with skilled migrant qualification-matched employment in their host country and its outcomes. We also highlight the role of multilevel factors and moderating variables associated with skilled migrants’ possibility of obtaining qualification-matched employment. Our review has implications for human resource scholars and practitioners concerned with skilled migrants’ employment and labor market. 相似文献

Firms need to respond to the increasing competition and change of the current New Normal environment by being more innovative, and especially in developing new business models. This paper seeks to explore how microfoundations, particularly with respect to human resource management, play a key role in facilitating innovation in business models through the development of key needed capabilities. Four themes are identified with respect to business model innovation (BMI) in the New Normal: BMI as an enabler to create and operate across industries and product-markets; BMI as a mechanism for firms to better navigate changing institutional landscapes; BMI as giving rise to business model portfolios; and concurrent and cumulative innovations that can lead to BMI. This paper also develops a conceptual framework that presents a synoptic view of the five essential capabilities for BMI, which include analogical reasoning, sensemaking, dynamic capabilities, organisational ambidexterity, and organisational learning. Finally, it is shown how the microfoundations of a bespoke, development-oriented BMI HR architecture can support the advancement of these capabilities and thus contribute to the strategic HR literature. 相似文献

This article examines the main determinants of divorce rates in Spain for the period 1995 to 2010. According to the results, the so-called Express Divorce Law (passed in 2005) seems to be positively associated with divorce rates in the short term. Income level and growth, female employment rate, and the proportion of foreign population are also positively related to divorce rates. However, as expected, the percentage of conservative vote seems to have a negative impact. 相似文献
