The objective in this study is to evaluate the mediating role of personal factors affecting the Web behaviour and in turn the length of Web sessions as a highly‐subjective variable among individuals. This could be used to explain and improve the users’ experience of being and acting in the Web. The present study uses a flow‐ versus goal‐directed theoretical and practical approach to determine the influence of personal factors on Web behaviours and session lengths. A field study of 209 Web users was conducted to validate measures used to operationalise model variables and to test the hypothesised network of relationships using partial least squares (PLS) as a second‐generation multivariate analysis technique. The study findings indicate that experiential behaviour, followed by goal‐directed behaviour, has the largest influence on the lengths of Web sessions.

Performance feedback about whether responses are correct or incorrect provides valuable information to help guide learning. Although feedback itself has no extrinsic value, it can produce subjective feelings similar to “rewards” and “punishments.” Therefore, feedback can play both an informative and a motivational role. Over the past decade, researchers have identified a neural circuit that processes reward value and promotes reinforcement learning, involving target regions of dopaminergic input (e.g., striatum and ventromedial prefrontal cortex). Importantly, this circuit is engaged by performance feedback even in the absence of reward. Recent research suggests that feedback-related brain activity can be modulated by motivational context, such as whether feedback reflects goal achievement, whether learners are oriented toward the informative versus evaluative aspect of feedback, and whether individual learners are motivated to perform well relative to their peers. This body of research suggests that the brain responds flexibly to feedback, based on the learner’s goals.

A systems approach to the family as a self‐regulating, goal‐directed system is developed. It is viewed in terms of socio‐legal boundaries delimiting certain role relationships and interactional patterns or action‐strategies, which are regulated by a hierarchy of steering principles and meta‐principles. Steering principles include adaptation, self‐regulation, control of interaction and morphogenesis, while meta‐principles include values, identity and meaning. The applicability of systems theory to family policy is discussed; its predictive possibilities should not be used to control, but to facilitate morphogenesis.

The rapid progress of neuroscience and the interdisciplinary collaboration between neuroscience and psychology have begun to provide valuable insights for understanding the dynamic and implicit nature of human motivation by identifying the in vivo neural mechanism of motivation. One of the fundamental questions in the field of the neuroscience of motivation is what neural mechanisms underlie the direction, intensity, and guidance of our motivation and subsequent actions. This prologue explains how neuroscience can contribute to the understanding of human motivation. To accomplish this purpose, we present what neuroscientific data look like, identify 13 key motivation-relevant brain structures, and introduce 3 key motivation-centric brain circuits – namely, the reward circuit, the value-based decision-making pathway, and the self-regulation/self-control network.

In recent years, it has become evident that self-regulation plays a central role in human functioning, including learning and achievement in school. Although there are different definitions of self-regulation, there is general consensus that it refers to a multi-component, iterative, self-steering process that targets one's own cognitions, feelings, and actions, as well as features of the environment for modulation in the service of one's own goals (Boekaerts, Maes, & Karoly, 2005). Educational psychologists agree that learning in the classroom involves cognitive and affective processing and is heavily influenced by social processes. This implies that students should be able and willing to regulate their cognitions, motivation, and emotions, as well as to adapt to the social context in order to facilitate their learning. Yet, there is at present neither a uniformly accepted definition of self-regulation nor that of self-regulated learning. Most theorists agree that self-regulation in the classroom is neither an all-or-none process nor a property of the learning system. Rather, it consists of multiple processes and components that interact in complex ways. Definitions have focused either on the structure of self-regulation, describing the different components of the self-regulation process, or on the processes that are involved.

Imprisonment is associated with far-reaching restrictions of personal autonomy, which critically depends on the sense of agency (SoA), i.e. the experience of control over one’s own actions and the consequences of these actions. Lack of personal choice and coercion to engage in specific actions disrupt the neurocognitive basis of SoA, which can have a profound impact on social behaviour, self-reliance and well-being. The purpose of this conceptual paper is to address the relationship between autonomy, choice restrictions and SoA in prisoners and the ability to reenter society after release.

This conceptual paper integrates existing empirical evidence from research on the role of personal autonomy and lack of freedom in prison and recent research using neurocognitive methods to study the processes underlying the effects of choice restrictions and coercion on SoA.

Building on prior empirical observations, the authors suggest that investigating how and when imprisonment undermines SoA through the restriction of personal choice can provide valuable insights into prisoners’ challenges in regulating and organizing their behavior and to accommodate the rules of society.

This conceptual paper offers directions for future research to further our understanding of autonomy restrictions on SoA in prison and its downstream consequences for societal reintegration.

Twenty-five years ago IJPDLM published “Integrating the Supply Chain” (Stevens, 1989). The purpose of that original work was to examine the state-of-the-art in supply chain management (SCM). There have been substantial changes to the landscape within which supply chains function and changes to supply chains themselves. Given these changes it is appropriate to re-visit what is the new state-of-the art and determine whether the 1989 conceptualization requires extending. The authors also attempt to assess whether the evolution of SCM is associated with improved financial performance. The paper aims to discuss these issues.

The authors take a conceptual approach to suggest that SCM is undergoing a transition to devolved, collaborative supply chain clusters. In addition, the authors consider imperatives and models for supply chain change and development. In line with the 1989 work, many of the observations in this invited paper are based on the primary author’s experience. The authors use a selection of financial data from leading firms to assess whether benefits attributed to SCM and changes in supply chain operating models have affected financial performance.

The authors formalize a model for the dynamics of SCM change. The authors also synthesize a number of models of SCM that extend the original, highly cited work. These include goal-oriented networks and devolved, collaborative supply chain clusters. The authors also find the associations between the evolution of SCM and measures of firm financial performance over time to be equivocal.

This work proposes two additional operating models that firms can implement in order to improve the efficacy of their supply chains.

The authors extend Stevens (1989) original work by synthesizing a number of additional models for SCI.

The purpose of this paper is to identify the key values individuals believe in and their interpretation in the context of entrepreneurial behaviour. The study is predicated on the prior work of Krueger (2007) and specifically on the premise that “deep beliefs” underpin sense making, decision making and subsequent entrepreneurial behaviour.

The study utilised an inductive and interpretive research design within a constructivist paradigm. In phase one, Schwartz’s (1992) 54 values inventory was used to discover a core value-set associated with entrepreneurial behaviour. The results were later used as an “aide-memoire” during the second phase of in-depth interviews with 30 self-selected entrepreneurs. Interviews focused primarily on the meaning individuals attributed to those fundamental values they associated with entrepreneurial behaviour. The resulting narrative was subjected to discourse analysis and categorised into relevant themes.

Self-determined human action is based on a specific set of values which the individual uses to make decisions about how to behave in situations that are meaningful to them. Engaging in entrepreneurship is one form of self-determined behaviour that enables the individual to express and satisfy a variety of different fundamental needs. Four specific values are believed to be critical to the motivation of entrepreneurial behaviour, namely, independence, creativity, ambition and daring. The meaning attributed to each of these values is consistent with that attributed to self-determinism, self-efficacy and the identity of participants associated with entrepreneurship.

There are limitations to this research and the extension of the findings to a generalised population comprising individuals who may, or may not, behave entrepreneurially. This is not to say that such individuals hold values substantially different in other roles or areas of their lives outside a purely business context. The values rated by participants in this study had relevance to their view of entrepreneurial behaviour and were confined to a business perspective.The variability in meaning attributed to these values is however likely to produce a common thread focusing on control, creativity and goal-directed behaviour.

The study strongly suggests the presence of a specific value-set associated with entrepreneurial behaviour. The shift in emphasis to independence and being ambitious, at the expense of being creative and daring, represents one explanation for the episodic nature of entrepreneurial behaviour among individuals. The data further reveal differences in entrepreneurial behaviour within urban and rural contexts with the former being more tolerant of entrepreneurial activity because of its inherent cultural diversity

Similarly, all participants have assimilated several different identities for the different social roles they occupy. Within those varying roles there is the possibility that both individual and group values will differ from what is reported here. The purpose of the study was to isolate as far as possible entrepreneurial behaviour and its core values independently from other types of behaviour and values. However, the likelihood does exist that values held by some individuals from other spheres of their lives could take precedence over their entrepreneurial role and thus influence their survey results.

The value of this study lies in exposing the underlying motivations that cause entrepreneurial behaviour. The study also discovered that shifts occur in the belief structure causing individuals to engage in managerial behaviour in preference to entrepreneurial behaviour at critical stages in the business life-cycle. The study further identifies cultural differences in individualistic vs collectivist cultures and the degrees to which entrepreneurial behaviour is accepted within urban vs rural environments.

The aim of this study is to diagnose the Egyptian political system from the perspective of the viable system model (VSM). That in turn gives us significant insights on how to improve the distribution and control of power in Egypt to warrant greater autonomy and representativeness in the branches of government.

The proposed diagnostic framework in this study was accomplished by applying the principles and aspects of Stafford Beer's VSM to the three state powers of Egypt: the executive, legislative and judiciary. In addition, it adopts the guidelines for applying the VSM described by both Stafford Beer and José Pérez Ríos.

The presented framework in this study shows a comprehensive explanation of the essential functions and their distribution among the entities of the Egyptian political system. In addition to that, the findings give us insights about the need for greater autonomy and self-organization among the political system's entities. Greater communication, consensus, cooperation and coordination is needed to achieve balance, regulate the interactions between them and to monitor each other without intervention. This, in turn, would ensure greater representation of citizen demands and expectations, and protect and guarantee their rights and freedoms.

The modeling of the Egyptian political system from a VSM perspective suggests the necessity of reform of the political system by a clear division of functions and tasks within the operational entities and subentities, decentralization of power structures and utilization of the decision marketing mechanism to reach public acceptance. The application of the VSM, for the sake of diagnosing and designing the viability of separation of power, can be considered as highly original.
