AI planning systems tend to be disembodied and are not situated within the environment for which plans are generated, thus losing information concerning the interaction between the system and its environment. This paper argues that such information may potentially be valuable in constraining plan formulation, and presents both an agent- and domain-independent architecture that extends the classical AI planning framework to take into account context, or the interaction between an autonomous situated planning agent and its environment. The paper describes how context constrains the goals an agent might generate, enables those goals to be prioritised, and constrains plan selection.

The entrepreneurship literature teaches us that the aspirations and competence of SME owner-managers as well as their strategic management behaviour can influence both the development and performance of their firm. However the research issues that surround the owner-manager's business venturing mode, that is, whether he or she has created a new firm, acquired an already existing firm, or acceded to a family firm's leadership and ownership by succession and/or inheritance, have rarely been addressed in an integrated manner. Now, founders, acquirers and successors may have fundamentally different strategic profiles, that is, in terms of the strategic capabilities they aim to develop and the type of performance they seek for their firm. In aiming to identify individual correlates and organizational effects of the entrepreneur's business venturing mode, an empirical study of 357 Canadian and French SMEs was thus undertaken. The results reveal significant differences between the three groups of owner-managers, that is, between the 196 founders, 96 acquirers and 65 successors with regard to their competence and motivations and with regard to the strategic capabilities and business performance of their firm. The results also reveal the owner-manager's business venturing mode to be a significant predictor of the firm's market and HR capabilities as well as its growth, productivity and profitability.

The objective of this study is to explore entrepreneurial motivation in a least developed country (LDC), which can be divided into push factors and pull factors, without a priori separation between those which are necessity-driven and those which are opportunity-driven. This study shows that the premise "For people who start their own business in an LDC, push factors are more important than pull factors" can be rejected. In contrast to the findings from prior studies on entrepreneurship in LDCs, this study shows that push factors and pull factors are not mutually exclusive. In addition, this study shows that pull factors are even more important than push factors, and that therefore push factors only play a minor role for entrepreneurs. The overall implications are that motivation is a more combined, and nuanced construct, and that the Western concept of entrepreneurial motivation and method of measuring entrepreneurial motivation, are globally applicable.

The number of small businesses owned by women in the United States is on the rise, due to a variety of reasons. One business model, which is attractive to mothers who lead busy lives, is multi-level marketing. The purpose of this study is to examine the motives of mompreneurs and gain a better understanding of their experiences with the multi-level marketing business model. Data collection involved both a survey and phenomenological interviews. The results identified a variety of motivations for engaging in multi-level marketing, ranging from economic to brand relationships. The women utilised social media tools to access their social capital in order to advertise and sell products to a large network of other women. Moreover, they received significant support from their family and friends related to their business. Several success factors and challenges were identified, as was a finding related to the serial nature of multi-level marketing business ownership. Theoretical and managerial implications are discussed.

Despite the significant contributions of women in economic development nationally, the unrecognized attitude of the government, lack of existing legal framework and policies, vagaries of informal economy and changes in the social–economic landscape have accounted largely for the closure of female enterprises in the informal economy. Using Yoruba female textile traders as a case study because these women have broken the "glass ceiling" and made a success of their textile trading, this paper examined the dynamics of entry and motivations of Yoruba women in textile trading. The paper synthesized Social Capital Theory by Coleman and Social Action Theory by Max Weber to explain the issue. It utilized a qualitative method of data collection. Eight focus group discussions and forty in-depth interviews were used to collect information from the women participants who were purposively chosen. The data reveal that parents, family/kinship members and friends had great influence in the strategic entry of women into textile trading in the Balogun market and the subsequent development of women's entrepreneurial activities. Yoruba female textile traders were motivated into textile trading because of economic and cultural values attached to the trade. This data is essential toward policy formulation for women's entrepreneurial development in the informal economy. This paper argues that any policies implemented for women entrepreneurs in the informal economy must be conceived, formulated and implemented with an in-depth understanding of the nuanced elements in the cultural domain within the social system, which the existing literature has yet to capture.

Contemporary national development policy in many parts of the world is focused on the promotion of entrepreneurship. This is because policy makers see entrepreneurship as an important driver of economic development. Drawing on in-depth research in Ghana and Uganda, this paper provides a comparative analysis of the characteristics of entrepreneurs and their enterprises, their motives for choosing self-employment and the constraints to their businesses in Ghana and Uganda. Using a sample of over 1,000 micro and small entrepreneurs in each country, we found that Ghanaian entrepreneurs are much more motivated by necessity-driven motives while Ugandans are motivated by a combination of opportunity- and necessity-driven motives. Specifically, the factor analysis indicated that whereas Ghanaian entrepreneurs are significantly motived by “Work-family consideration” and “Low opportunity,” entrepreneurs in Uganda rated “Career consideration” and “Survival consideration” as their main motives for engaging in self-employment activities. On success, a much higher fraction of Ugandan entrepreneurs are found to be more successful than their Ghanaian counterparts. Comparatively, we found that Ghanaian businesses are significantly challenged with access to finance or credit; however, their counterparts in Uganda significantly face problems related to institutional weaknesses. Thus, from the factor analysis, “Financial problem” and “Institutional problem” were found to be significantly higher for Ghana and Uganda respectively. Hence, among others, Ghanaian policy makers can stimulate entrepreneurship by taking steps to reduce the level of financial constraints facing its entrepreneurs while in Uganda, much effort should be geared toward improving the business institutional environment.

It is well established in previous research that female and minority entrepreneurs are less successful with business ventures in comparison to whites and males. In that same literature, motivation and growth expectations have been shown to be positively associated with business success. This paper examines how motivations and business goals differ by gender and race and how they affect disparity in business outcomes. Using data from the Second Panel Study of Entrepreneurial Dynamics (PSED II), we find that stronger motivations for financial gain have a negative effect on business survival rate for black women and Hispanic men. In contrast, the effect is positive for black men and Hispanic women. When considering interactions between financial motivations, race and gender, various significant effects were found and are detailed in the paper. It is important for researchers and practitioners who want to promote entrepreneurship to understand the differences and adapt advisory and training curricula accordingly.

Entrepreneurs play a critical role in the socio-economic development of societies. Among these change agents, women entrepreneurs have drawn the attention of entrepreneurship scholars and policymakers recently. Nevertheless, there is a lack of attention to these entrepreneurs, especially in Arab countries. This chapter reviews the state of Algeria as an Arabic and Berber society. Therefore, after introducing the context, the chapter provides a historical overview of the country. Then, the authors review the main characteristics, motivations, and impacts of the Algerian female entrepreneurs. Afterwards, the gender-specific and constraints to women entrepreneurship in Algeria are discussed and finally, the chapter concludes with some future directions.

Recently the computational-neuroscience literature on animals' learning has proposed some models for studying organisms' decisions related to the energy to invest in the execution of actions ("vigor"). These models are based on average reinforcement learning algorithms which make it possible to reproduce organisms' behaviours and at the same time to link them to specific brain mechanisms such as phasic and tonic dopamine-based neuromodulation. This paper extends these models by explicitly introducing the dynamics of hunger, driven by energy consumption and food ingestion, and the effects of hunger on perceived reward and, consequently, vigor. The extended model is validated by addressing some experiments carried out with real mice in which reinforcement schedules delivering lower amounts of food can lead to a higher vigor compared to schedules delivering larger amounts of food due to the higher perceived reward caused by higher levels of hunger.
