A resistance element for an electrical strain gauge comprising, a thin elongated element of a substantially uniform mixture of finely divided carbon and silica and a resilient binder having an elasticity similar to that of phenolic resin.

As long ago as 1948, at the Royal Society Conference on Scientific Information, Professor E. N. da C. Andrade was protesting about scientists who write “matter that is unintelligible not on account of its difficulty but on account of the confusion of thought, the lack of sequence and the tangled, sometimes ungrammatical jargon in which it is expressed”. Have our university departments made any attempts to improve the speech? and writing of their students? Most employers complain strongly about the lack of linguistic skill among new graduates.

The Annual Fall Symposium took place on 11–12 November, 1985, at the Marriott‐LAX Hotel, Los Angeles, focusing on the theme: ‘PC Technology: Materials, Processes and Requirements for Entry to the '90s’.

This study examines the collaborative value practices of cause-based social entrepreneurship alliances. We investigate key drivers of value creation in such alliances.

The study utilizes a longitudinal case study design approach involving four northern Italian businesses for investigating the cause-based social alliances.

The study findings suggest that cause-based alliance differ from other business relationships due to social mission of the alliance and orientation of partners to a specific social cause. However, over time involved firm may pursue commercial interests.

The study utilizes a qualitative case study approach to examine the issues. This may have implications on generalizability of study findings. Further, the sample is limited to small firms, which limit its relevance for large firms.

Managers can utilize the study findings to guide the organizing process of a successful cause-based alliance and can implement it with positive outcomes for their firm.

This is one of the first study on the emerging phenomenon of cause-based social alliance. It contributes to the literature on social entrepreneurship. It informs and guides practitioners about motivations and drivers of such alliances.

This paper aims to contribute to the existing literature on social enterprises and business model innovation. Particularly, it sheds some light on those factors that turn a social innovation initiative into a success, both in terms of meeting social needs and achieving economic sustainability.

By using a grounded theory approach, an inductive comparative case study is conducted. Two work integration social enterprises in the hospitality and tourism sector are selected. Both companies are located in Barcelona (Spain) under the same legal regulation and economic situation and initially run a manufacturing business. Due to the economic crisis they were forced to reinvent themselves to survive. Data were collected from different sources and coded using content analysis procedures.

Results indicate that three factors, namely, value proposition, appropriate market research and stakeholder involvement, heavily contributed to firm’s success, corroborating previous studies. Furthermore, our study reveals that social need pressures and managerial trust on employees are additional factors that drive social business model innovation.

Changes in the demand, the rules governing the market or economic downturns are external drivers for demand-pull innovations. In such context, firms need to reformulate their business models if they wish to survive. Acknowledging the factors that help firms overcome these obstacles is of great interest for both academics and entrepreneurs.

Social innovation in business models is a topic still poorly defined in the literature, yet, its boundaries to other fields are still fuzzy. This paper aims to fulfill this gap by presenting the theoretical domain in which this topic fits in and evidencing those successful factors that should be considered when designing and implementing a business model innovation which may help other firms facing a similar process.

Social entrepreneurship is gradually becoming a potent driving force for economic and social development in developing countries as a result of governance deficits. The purpose of this study is to examine the determinant factors of successful social entrepreneurship in the emerging circular economy of Lebanon. The objective extends to exploring the mediating role of non-governmental organizations (NGOs) in the success of social entrepreneurship in Lebanon.

Using a cross-sectional survey design, the authors collected primary data from 389 social entrepreneurs through questionnaires in selected locations in Lebanon. The data collected were analyzed using descriptive and inferential statistics. The hypotheses were tested using linear regression and structural equation modeling (SEM) for predicting the impact of independent variable on the dependent variable. The validity, progressive and various models fits were tested using root mean square of approximation, root mean square of residuals, standard root mean square residuals, incremental fit index, fitness of the extracted and non-normal fit index.

The SEM estimations reveal that three main factors determine the success of social entrepreneurs in Lebanon, namely, environmental factors, psychological factors and prior experience. Moreover, the results reveal that support of NGOs positively moderates the relationships between the success of social entrepreneurship and two different variables (psychological factors and environmental factors), but failed to moderate the relationships between success of social entrepreneurship and four variables (experience, education, leadership and founding team composition).

The study contributes to the entrepreneurship and circular economy literature by explicating empirically the determinant factors of successful social entrepreneurship in Lebanon’s emerging circular economy. It also provides a fact-based social awareness on the role of local and international NGOs in supporting the social entrepreneurs in driving the idea of a circular economy. The study also validates multiple entrepreneurship theories.
