To review and address current approaches and limitations to modeling change over time in social entrepreneurship research.

The article provides a narrative review of different practices used to assess change over time. It also shows how different research questions require different methodologies for assessing changes over time. Finally, it presents worked examples for modeling these changes.

Our review suggests that there is a lack of research in social entrepreneurship that takes into account the many different considerations for addressing how time influences outcomes.

This chapter introduces an analytic technique to social entrepreneurship that effectively models changes in predictors and outcomes even when data are non-normal or nested across time or levels of analysis.

Clusters of foreign manufacturing plants are traditionally explained by characteristics of the entry location such as immobile resources or agglomeration advantages, but an alternative explanation is that social or economic relations among firms in the home country facilitate interorganizational learning about entry locations. Such interorganizational learning reduces uncertainty, leading to heterogeneous diffusion of the plant location choices among organizations that are socially proximate in the home country. We examine this hypothesis through analysis of the effect of industry, lending ties, and board interlocks among Japanese firms on their entries into Europe, and find that shared industry and structural equivalence in the board interlock network are strong predictors of mimetic nation choice. The findings suggest that nation choices follow an innovation diffusion pattern, and that Japanese firms have paths of influence like those of U.S. firms.

Examines the effects of a three‐year mentoring programme on the academic achievement of high ability year 13 students at a New Zealand high school. The programme’s purpose was to improve the academic results in the university bursary examination. The study covered a period of six years. The programme matched each selected student with a staff member in a flexible mentoring arrangement which focused on generic skills such as study skills, goal setting and time management. Protégés and mentors felt that the programme was enjoyable and successful. Protégés felt that they gained from the skills they were taught. Statistical analysis indicates that the programme did not have a measurable effect on the academic achievement of the mentored students. Reasons for this and implications for programmes of this kind are discussed.

The literature on international entrepreneurship offers two competing views on why new ventures internationalize: (a) the nature of the opportunity pulls them international or (b) the founder pushes the firm international. While these two internationalization drivers are not independent, they do represent unique causal mechanisms. Previously, the tools available to understand the entrepreneur’s disposition toward internationalization were limited. The present study uses the theoretical foundation of the international entrepreneurial orientation construct and from it develops and tests an attitudinally-based individual-level measure of disposition toward internationalization. To ensure the validity and reliability of the new measure, termed International Entrepreneurial Orientation Disposition, studies were conducted to: develop new scale items, examine their psychometric properties and construct validity, and demonstrate criterion validity. A strong measurement model is developed using structural equation modeling (CFI = 0.93, RMSEA = 0.07), and the measure is shown to be useful as a predictor of perceived international venture attractiveness.

In this study, the foam dyeing technology was applied to dye cotton knitted fabric for achieving the surface-dyed result. The T-shirt made by this surface-dyed fabric could easily obtain the wash-out effect after garment laundering. The pigment dyeing performances in foam dyeing were system studied. Colour strength, colourfastness and serviceability of fabrics dyed with the methods of foam-padding and liquid-padding were evaluated and compared. Results show that surface dyeing for cotton-knitted fabric with foam media could overcome the shortcoming of poor penetration in foam dyeing method, and turn the poor penetration into the superiority for obtaining the surface-dyed result. The serviceability such as water absorption and handle property was also well improved in foam dyeing method. Finally, the advantages of energy saving and reducing chemical usage were implemented throughout the dyeing process.

THE study of the flight of birds has provided and will still provide much valuable information for tiie progress of human flight. Many suggestions for the improvements of wings by the use of special wing tips owe their existence to the observation of nature. In spite of such suggestions, free‐flight experimentation—as far as published work goes—is still rather rare and restricted in scope. This reluctance may be due to practical design considerations (handling) as well as to the necessity of making the conventional aileron as efficient as possible; it may also be caused by the impression that experiment in this direction is not worth the effort.

The purpose of this paper is to explore relationships between proactive personality and organizational citizenship behaviors (OCBs). Moderators between these constructs are proposed in order to explain varying levels of dispositional impact on work behavior. These relationships were also tested to see whether proactive personality should be considered a strong or weak trait. Trait activation theory and social exchange theory are used to develop hypotheses.

Data collected via a targeted sampling strategy from 178 supervisor-subordinate dyads spanning multiple industries and organizations were used. Hypotheses were tested using hierarchical linear regression.

Results indicate a positive relationship exists between proactive personality and organizationally directed citizenship behaviors, and that this relationship is moderated by both job autonomy and job meaning.

The paper is one of the first to explore the relationship between proactive personality and citizenship behaviors directed at the organization. It also bolsters the strong trait argument by demonstrating that, even in conditions of low autonomy and meaning, highly proactive individuals will still perform OCBs.

IN the tailless aeroplane, side‐slip motions during take‐off and landing manoeuvres are specially undesirable, since it tends to be deficient in lateral stability, as we have seen. Hence, arrangements which provide for early compensation of unintentional side‐slipping may have some justification.

Retailers have long been aware that weather affects the sales of a myriad of products, but until now, most were not in a position to manage the risks weather presents. Rising weather variability combined with advances in weather-index financial instruments have prompted new interest in investigating the relationship between sales and weather. The purpose of this paper is to explore the impact of changes in weather on UK retail sales, to estimate the contribution of weather to sales, and evaluate the maximum potential loss caused by adverse weather, for each season and retail sector.

The authors present a methodology to identify and quantify the extent to which a company is exposed to weather risks, in order to incorporate them into its risk management policy and take actions to mitigate these risks. For each season and each retail category, the authors provide a measure of the impact of weather on sales that can be used as a benchmark to analyse sales performance.

The authors propose a new risk assessment indicator to evaluate the potential losses caused by adverse weather (WeatherRisk). The authors show that intra-annual changes in weather significantly affect retail sales. The exposure of retail categories to weather are not the same depending on the season, and the response of individual retail categories to the same change in weather varies considerably. Although temperature is a predominant explanatory variable, the authors show that weather-sensitivity analysis should include precipitation, humidity rate and wind.

One limitation of this study is that the authors individually compute WeatherRisk for each significant weather variable. Further research could explore new approaches to evaluate Total WeatherRisk, which take into account potential multicollinearity issues between weather variables.

The methodology allows retailers to measure the effects of weather on sales performance, evaluate the risks at stake, and protect sales and margins from weather risks, with newly available index-based financial instruments. Managers may now actively use weather as a differential advantage, and at the same time focus their efforts on improving resiliency to increasing climate variability.

In this paper, the authors produce a detailed analysis of the exposure of each retail sectors to unseasonal weather. This is the first time all retail sectors are analysed and ranked per season at a national level. The authors provide managers with actionable information to improve their understanding of how weather impact sales over each season, and to allow them to structure weather-index-based instruments with financial partners.
