In approaching this Special Issue on Foresight, Innovation and Entrepreneurship (FI&E) we considered that globalisation and rapid modernisation were increasingly creating the need for social reflexivity. We thought that in respect to the production and diffusion of innovations, both social and technical, that the landscape for new enterprise was characterised by widening change horizons and deeper ethical concerns. As a consequence of the greater demand for innovation to achieve economic prosperity, it was conceived that 'unforesightful' innovation may have irreparable affects on social and ecological systems and uncertain implications for our futures. Therefore, we considered a new intellectual alliance between FI&E was potentially a matter of human survival. New approaches to thinking about how and what we innovate, the choices we face for new enterprise creation and the influence of infrastructure for generating entrepreneurship, we considered, would need to emerge if we are to positively impact human and planetary sustainability in the 21st century. Hence this special issue was designed to bring together cross-disciplinary research aimed at exploring the synergies between foresight, innovation and entrepreneurship and the way in which these connections may be taking place in both the practical and theoretical sense.

Action learning / research is a broad field of research with deep roots in the 20th century. Unlike futures studies, which is more content oriented (i.e., the futures of health, peace futures, global futures), action learning / research is process and methodology oriented – addressing the manner in which research is done, rather than what is researched. At its core it is collaborative learning for social change. This is particularly important because, in this age of heterogenous changes and multi-fold social challenges, we need to be able to bridge learning about our futures with action and innovation in the present, in a way that is effective and accessible for lay communities and organisations, not just experts.

It is a very rare event when a book by a senior Chinese policy adviser gets published in English. More often the accepted format is biography or auto-biography, generally published once the person has retired. This book was first published by Xinhua Press in Chinese in a longer version in 2009. Initially it was directed at the Chinese reader, more specifically the Chinese cultural academic, and for this reason some of the material is not repeated in this abridged version. Nevertheless, it is important to point out that the author represents four speaking positions, and the messages that emerge from this work need to be contextualized accordingly.

Service oriented architecture (SOA) is an architectural style for building software systems based on services. Especially in those scenarios where services implement business processes, complex conversations between the services occur. Service choreographies are a means to capture all interaction obligations and constraints from a global perspective. This article introduces choreographies as an important artifact for SOA, compares them to service orchestrations and surveys existing languages for modeling them.

In the university education arena, it is becoming apparent that traditional methods of conducting classes are not the most effective ways to achieve desired learning outcomes. The traditional class/method involves the instructor verbalizing information for passive, note-taking students who are assumed to be empty receptacles waiting to be filled with knowledge. This method is limited in its effectiveness, as the flow of information is usually only in one direction. Furthermore, “It has been demonstrated that students in many cases can recite and apply formulas in numerical problems, but the actual meaning and understanding of the concept behind the formula is not acquired (Crouch & Mazur)”. It is apparent that memorization is the main technique present in this approach. A more effective method of teaching involves increasing the students’ level of activity during, and hence their involvement in the learning process. This technique stimulates self- learning and assists in keeping these students’ levels of concentration more uniform. In this work, I am therefore interested in studying the influence of a particular TLA on students’ learning-outcomes. I want to foster high-level understanding and critical thinking skills using active learning (Silberman, 1996) techniques. The TLA in question aims to promote self-study by students and to expose them to a situation where their learning-outcomes can be tested. The motivation behind this activity is based on studies which suggest that some sensory modalities are more effective than others. Using various instruments for data collection and by means of a thorough analysis I present evidence of the effectiveness of this action research project which aims to improve my own teaching practices, with the ultimate goal of enhancing student’s learning.

The focus of this special volume of CSI on research with and by children reflects a major paradigm shift in child research - a shift from a focus on the child as object of to a focus on the child as subject (and actor) in research (see Mason and Hood 2010). In his lead article in the first issue of this journal (2008), Asher Ben-Arieh highlighted the way in which the child indicators movement reflects this paradigm shift, outlining the way in which new directions in measuring and monitoring child well-being were leading to new roles for children in this process. He noted the importance of including children’s own perspectives on their well-being and argued that ‘incorporating children’s subjective perceptions is both a pre-requisite and a consequence of the changes historically in the measuring and monitoring of child well-being’ (p.13). This special issue again takes up this agenda of the child as subject in research...

In this volume we compile and comment on a collection of some of the most important works on nascent entrepreneurship that have appeared in the last two decades. We do not go further back than that because up until1992 hardly any systematic research on the pre-operational stage of business creation was undertaken. In that year, the terms 'nascent entrepreneur' and 'nascent venture' appear for the first time in the research literature (Reynolds and Miller, Chapter l, 1992; Reynolds and White, 1992). This signals the emergence of a new research paradigm designed to study• business creation processes empirically at very early stages, before an operational firm has come into existence. The most central feature of this type of research is that it identifies a statistically representative sample of nascent entrepreneurs (NEs)- people engaged in ongoing but not yet operational business start-ups- via screening interviews with a very large random sample of adults. The overarching research questions pursued in this emerging research tradition are the following: 1. What proportion of individuals (in various population subgroups) are trying to start a new business at any given time? 2. What led them to engage in the creation of a new business? 3. What characteristics and behaviors associated with the founder(s), the venture, the environment and the process are associated with persistence, progress and success in trying to start a new business?

On 20 September 2001, the former US President, George W. Bush, declared what is now widely, and arguably infamously, known as a ‘war on terror’. In response to the fatal 9/11 attacks in New York and Washington, DC, President Bush identified the US military response as having far-reaching and long-lasting consequences. It was, he argued, ‘our war on terror’ that began ‘with al Qaeda, but … it will not end until every terrorist group of global reach has been found, stopped and defeated’ (CNN 2001). This was to be a war that would, in the words of former British Prime Minister, Tony Blair, seek to eliminate a threat that was ‘aimed at the whole democratic world’ (Blair 2001). Blair claimed that this threat is of such magnitude that unprecedented measures would need to be taken to uphold freedom and security. Blair would later admit that it was a war that ‘divided the country’ and was based on evidence ‘about Saddam having actual biological and chemical weapons, as opposed to the capability to develop them, has turned out to be wrong’ (Blair 2004). The failures of intelligence ushered in new political rhetoric in the form of ‘trust me’ because ‘instinct is no science’ (Blair 2004). The war on terror has been one of the most significant international events in the past three decades, alongside the collapse of the former Soviet Union, the end of apartheid in South Africa, the unification of Europe and the marketization of the People's Republic of China. Yet, unlike the other events, it will not be remembered for advancing democracy or sovereignty, but for the conviction politics of particular politicians who chose to dispense with international law and custom in pursuit of personal instincts that proved fatal. Since the invasions of Afghanistan in October 2001 and …

In this study, we explore the population genetics of the Russian wheat aphid (RWA) (Diuraphis noxia), one of the world’s most invasive agricultural pests, in north-western China. We have analysed the data of 10 microsatellite loci and mitochondrial sequences from 27 populations sampled over 2 years in China. The results confirm that the RWAs are holocyclic in China with high genetic diversity indicating widespread sexual reproduction. Distinct differences in microsatellite genetic diversity and distribution revealed clear geographic isolation between RWA populations in northern and southern Xinjiang, China, with gene flow interrupted across extensive desert regions. Despite frequent grain transportation from north to south in this region, little evidence for RWA translocation as a result of human agricultural activities was found. Consequently, frequent gene flow among northern populations most likely resulted from natural dispersal, potentially facilitated by wind currents. We also found evidence for the longterm existence and expansion of RWAs in China, despite local opinion that it is an exotic species only present in China since 1975. Our estimated date of RWA expansion throughout China coincides with the debut of wheat domestication and cultivation practices in western Asia in the Holocene. We conclude that western China represents the limit of the far eastern native range of this species. This study is the most comprehensive molecular genetic investigation of the RWA in its native range undertaken to date and provides valuable insights into the history of the association of this aphid with domesticated cereals and wild grasses.

Does heat have a cooling effect on culture? Sweat argues the reverse: culture thrives in the subtropical zones. While acknowledging that the subtropical generates ambivalence—being cast as alternately idyllic or hellish—Sweat nonetheless seeks to develop the specific voices of subtropical cultures. The uneasy place of this sweaty discourse is explored across art, literature, architecture, and the built environment. In particular, Sweat focuses on the most commonly experienced situation, the everyday house. While it addresses subjects from Japan, Brazil, and France, Sweat centres on Brisbane, Queensland—long in the shadow of Sydney and Melbourne in the Australian cultural psyche—due to its enduring and self-conscious attention to subtropical living.

Volume 15 of Sociological Studies of Children and Youth (SSYC) presents a rich description of children’s and young people’s disputes. Children and young people live and experience their youth in a variety of contexts, settings and situations in contemporary society, and the studies discussed in this volume draw on empirical data to investigate the interactional procedures used by children and young people as disputes arise in varying contexts of their everyday life. The aim of this volume is to extend current understandings of on children’s disputes by examining how, in the varying arenas and social worlds of children and young people, matters of ownership, alignment and social and moral order are always at play. Applying a sociological perspective, the research papers in this special volume show that disputes can offer analytic opportunities to examine, and make visible typically unseen social and moral orders. This consideration provides rich accounts of dispute practices within social and institutional contexts.

The skyrocketing trend for social media on the Internet greatly alters analytical Customer Relationship Management (CRM). Against this backdrop, the purpose of this paper is to advance the conceptual design of Business Intelligence (BI) systems with data identified from social networks. We develop an integrated social network data model, based on an in-depth analysis of Facebook. The data model can inform the design of data warehouses in order to offer new opportunities for CRM analyses, leading to a more consistent and richer picture of customers? characteristics, needs, wants, and demands. Four major contributions are offered. First, Social CRM and Social BI are introduced as emerging fields of research. Second, we develop a conceptual data model to identify and systematize the data available on online social networks. Third, based on the identified data, we design a multidimensional data model as an early contribution to the conceptual design of Social BI systems and demonstrate its application by developing management reports in a retail scenario. Fourth, intellectual challenges for advancing Social CRM and Social BI are discussed.
