Project-based organisations : overcoming lack of trust and social networks within small and medium project teams

In sustainable development projects, as well as other types of projects, knowledge transfer is important for the organisations managing the project. Nevertheless, knowledge transfer among employees does not happen automatically and it has been found that the lack of social networks and the lack of trust among employees are the major barriers to effective knowledge transfer. Social network analysis has been recognised as a very important tool for improving knowledge transfer in the project environment. Transfer of knowledge is more effective where it depends heavily on social networks and informal dialogue. Based on the theory of social capital, social capital consists of two parts: conduits network and resource exchange network. This research studies the relationships among performance, the resource exchange network (such as the knowledge network) and the relationship network (such as strong ties network, energy network, and trust network) at the individual and project levels. The aim of this chapter is to present an approach to overcoming the lack of social networks and lack of trust to improve knowledge transfer within project-based organisations. This is to be done by identifying the optimum structure of relationship networks and knowledge networks within small and medium projects. The optimal structure of the relationship networks and knowledge networks is measured using two dimensions: intra-project and inter-project. This chapter also outlines an extensive literature review in the areas of social capital, knowledge management and project management, and presents the conceptual model of the research approach.

Mechanical properties of advanced tissue engineering scaffold architectures

In tissue engineering, porous scaffolds are used as a temporal support for tissue regeneration through cell adhesion, proliferation and differentiation. Besides applying a suitable material that is both biocompatible and biodegradable, the architectural design of the porous scaffold can be of essential for successful tissue regeneration. The architecture is of great influence on mechanical properties and transport properties of nutrients and metabolites1.

Collaboration based on web services

Web services are software components designed to support interoperable machine-to-machine interactions over a network, through the exchange of SOAP messages. Since the underlying technology is independent of any specific programming language, Web Services can be effectively used to interconnect business processes across different organizations. However, a standard way of representing such interconnections has not yet emerged and is the subject of an ongoing debate.

Extending Alexander’s ecological dominance-social competition (EDSC) evolutional model

Alexander’s Ecological Dominance and Social Competition (EDSC) model currently provides the most comprehensive overview of human traits in the development of a theory of human evolution and sociality (Alexander, 1990; Finn, Geary & Ward, 2005; Irons, 2005). His model provides a basis for explaining the evolution of human socio-cognitive abilities. Our paper examines the extension of Alexander’s model to incorporate the human trait of information behavior in synergy with ecological dominance and social competition as a human socio-cognitive competence. This paper discusses the various interdisciplinary perspectives exploring how evolution has shaped information behavior and why information behavior is emerging as an important human socio-cognitive competence. This paper outlines these issues, including the extension of Spink and Currier’s (2006a,b) evolution of information behavior model towards a more integrated understanding of how information behaviors have evolved (Spink & Cole, 2006).

Object identification based on 3D spatial models of construction sites

On obstacle-cluttered construction sites, understanding the motion characteristics of objects is important for anticipating collisions and preventing accidents. This study investigates algorithms for object identification applications that can be used by heavy equipment operators to effectively monitor congested local environment. The proposed framework contains algorithms for three-dimensional spatial modeling and image matching that are based on 3D images scanned by a high-frame rate range sensor. The preliminary results show that an occupancy grid spatial modeling algorithm can successfully build the most pertinent spatial information, and that an image matching algorithm is best able to identify which objects are in the scanned scene.

Challenges in the supervisory boardroom : an exploratory study in the Netherlands

As a consequence of recent corporate governance reforms, the work of supervisory board members in the Dutch two-tier system has become more complex. The objectives of this study are to gain more insight in the current challenges that supervisory board members face and assess whether they are well-equipped to manage them. Based on a combination of an analysis of self-assessment reports, a web-based survey and semi-structured interviews, we conclude that the major challenges of supervisory board members lie in the field of interaction and collaboration with executives. Distinct ‘challenge areas’ were relatively often perceived as problematic as well as important, highlighting the need to improve the current functioning of boards. With regard to the skills that are present on supervisory boards, we find that individual qualities, like integrity, professionalism and knowledge, are better recognized than collective qualities for the supervisory board as a whole. In particular, openness and honesty are seen as important, but often lacking. The paper highlights several implications for scholars and practitioners.

Adam Smith's dinner

In 1961, the East German government erected what they claimed was an anti-capitalist barricade. In 1989, this barricade was dismantled by those whom it was supposed to keep apart: the forces it was intended to contain had overwhelmed it. In the aftermath, the victims of Stalinist oppression and the planned economy opted for radical change. Some might have hoped that they would intellectually march resolutely westwards towards the forms of social democracy that had proven so successful in their nearest neighbours – Scandinavia, Germany and Austria – and stop when they had reached a point on the political spectrum with which they felt comfortable, and which worked for them. Unfortunately, they went to the opposite end of political economy. That choice was celebrated by those theorists who wanted our own countries to move in the same direction. Eastern Europe suffered a decline of 50% in its GDP. Much earlier in 1653, Peter Stuyvesant had erected an earth and wooden wall to protect the westernmost settlement of a great commercial nation from those they imagined to be barbarians. In 1699 Stuyvesant’s barrier was dismantled by the British, who replaced it with a street named after the wall. So it came to be that one of the most inconsequential walls in history became one of history’s most famous streets. I am not sure if the Dutch had left some tulip bulbs on either side of the wall, perhaps as a reminder of capitalism’s first bubble, and an inspiration to later bubbles. However, many of the victims of the latest burst bubble are pretty keen to tear down that Wall.1 As in 1989, they want to take action against the guardians of the system that failed them. And the more they suffer, the more likely it is that they will demand radical change, and the more likely that the resulting change will go too far – as seems to have been the case in Eastern Europe after the terminal crisis of communism, and in the majority of democracies that fell in the dozen years following the Great Crash. The current reaction is so strong that some are even wondering what role there will be for markets. I was invited to address a conference in the EU Parliament last November on the topic ‘Capitalism: Quo Vadis?’, where I apologized to the international audience that the topic was posed in a dead European language because the answer to this question is not going to be determined by the west alone. The problems we have been addressing emerged in the west and have affected the rest. However, the answers will not come, solely from the west, and may even come primarily from the south and the east.

The changing role of the supervisory board chairman: the case of the Netherlands (1997-2007)

Over the last ten years, the corporate governance context in most Western countries has changed as a result of irregularities, increased regulation, heightened societal expectations and shareholder activism. This paper examines the impact of the changing context on the role of chairmen of supervisory boards in the Netherlands. Based on a combination of thirty semi-structured interviews with board members of leading Dutch corporations and secondary data on the position of supervisory board chairmen at the top-100 listed firms in the Netherlands, the study reveals that board chairmen have become increasingly involved in both their control and service roles. While the demographics (i.e., age, tenure, gender and nationality) of chairmen have hardly changed over the last decade, chairmen are spending considerably more time on boards and committees, have reduced the number of board interlocks and have become more active on the forefront of the corporate governance discussion. The paper highlights several implications for scholars and practitioners.

Georg Calixtus, Isaac Casaubon, and the Consensus of Antiquity

This article explores the relationship between Georg Calixtus (1586-1656) and Isaac Casaubon (1559-1614). It does this in order to highlight an oversight in the existing literature concerning Calixtus, and to encourage scholars to revisit the work of Early Modern figures who have previously been considered only from modern disciplinary perspectives. By emphasizing the relationship between Calixtus and Casaubon, this article argues that Calixtus was potentially exposed to much broader circles of intellectual debate than has previously been considered, and that a reevaluation of his work in light of these debates is therefore in order.

A human factors investigation into the unavailability of active warnings at railway level crossings

This paper discusses human factors issues of low cost railway level crossings in Australia. Several issues are discussed in this paper including safety at passive level railway crossings, human factors considerations associated with unavailability of a warning device, and a conceptual model for how safety could be compromised at railway level crossings following prolonged or frequent unavailability. The research plans to quantify safety risk to motorists at level crossings using a Human Reliability Assessment (HRA) method, supported by data collected using an advanced driving simulator. This method aims to identify human error within tasks and task units identified as part of the task analysis process. It is anticipated that by modelling driver behaviour the current study will be able to quantify meaningful task variability including temporal parameters, between participants and within participants. The process of complex tasks such as driving through a level crossing is fundamentally context-bound. Therefore this study also aims to quantify those performance-shaping factors that contribute to vehicle train collisions by highlighting changes in the task units and driver physiology. Finally we will also consider a number of variables germane to ensuring external validity of our results. Without this inclusion, such an analysis could seriously underestimate risk.

Case studies of statutory interventions into the common law concept of charity

This paper considers four examples of statutory interventions into the common law concept of charity, namely, those of Pennsylvania, Barbados, the definition recommended by the Report of the Inquiry into the Definition of Charities in Australia, and the Recreational Charities legislation of the United Kingdom. It comments on some issues affecting each style of intervention. The paper does not argue against statutory intervention but submits that legislative changes are best made by deeming a particular purpose to be charitable, or not charitable, so that, except to that extent, the common law concept remains intact – this is the approach adopted by the Recreational Charities legislation.

Digital Storytelling within a Service-Learning Partnership: Technology as Product and Process for University Students and Culturally and Linguistically Diverse High School Youth

This chapter describes a university/high school partnership focused on digital storytelling. It also explains the multi-stage process used to establish this successful partnership and project. The authors discuss the central role that technology played in developing this university/high school partnership, a collaboration that extended the impact of a digital storytelling project to reach high school students, university students, educators, high school administrators, and the local community. Valuing a reflective process that can lead to the creation of a powerful final product, the authors describe the impact of digital storytelling on multiple stakeholders, including the 13 university students and 33 culturally and linguistically diverse high school youth who participated during the fall of 2009. In addition, the chapter includes reflections from university and high school student participants expressed during focus groups conducted throughout the project. While most participants had a positive experience with the project, complications with the technology component often caused frustrations and additional challenges. Goals for sharing this project are to critically evaluate digital storytelling, describe lessons learned, and recommend good practices for others working within a similar context or with parallel goals.

Predicting deadline tansgressions using event logs

Effective risk management is crucial for any organisation. One of its key steps is risk identification, but few tools exist to support this process. Here we present a method for the automatic discovery of a particular type of process-related risk, the danger of deadline transgressions or overruns, based on the analysis of event logs. We define a set of time-related process risk indicators, i.e., patterns observable in event logs that highlight the likelihood of an overrun, and then show how instances of these patterns can be identified automatically using statistical principles. To demonstrate its feasibility, the approach has been implemented as a plug-in module to the process mining framework ProM and tested using an event log from a Dutch financial institution.

Comparing retail union strategy in a neoliberal context

Amongst the most vulnerable workers in a neoliberal world are retail employees. In many countries these low paid workers comprise around 10 per cent of the workforce. The retail labour market is highly feminised, in some countries quite youthful and often part time or in various forms of precarious employment. The industry and its unions have however rarely been studied by academics. A three-country research team (United Kingdom, Australia and New Zealand) is investigating retail union strategy across these Anglophone countries in order to determine how, and how effectively, unions are contributing to workplace justice for retail workers.

One size fits one : customizing work through manager-employee exchange

While prior research has addressed how collective workplace outcomes are negotiated between employers and trade unions, less attention has been afforded to the ‘everyday’, micro-level exchanges between managers and employees in adjusting work, alongside the ‘standard’ terms and conditions set out in employment contracts. Building on previous work on idiosyncratic deals and requests for flexible scheduling, this article presents the findings from a survey of Australian parents which addressed manager-employee exchanges which led to customized work arrangements. The survey examined the frequency with which various employment terms and conditions were negotiated, who initiated the interactions, where they occurred, and the extent of perceived compromise. The study revealed that manager-employee exchanges occur frequently in the context of roles in nuclear and extended families, and are influenced by the parameters around which formal childcare and educational settings function. Women rated the exchanges as more important than men, but men and women were similarly comfortable with the interactions and satisfied with outcomes. The findings have important implications for managers and organizations in terms of balancing the goals of efficiency with employees’ preferences for workplace flexibility and other terms beyond those which are standardized.
