The emergence of human capital: Roles of social capital and coordination that drive unit performance

Empirical work on human capital has tended to focus on the direct effects of human capital on performance, whereas little attention has been paid to behaviours through which human capital influences performance. This study uses the “human capital emergence” model to examine relationships among human capital, social capital, coordination, and performance over a 2‐year period of time. Findings indicate that human capital, social capital, and coordination each influence performance. Human capital and social capital also positively predict coordination. Lastly, coordination mediates the relationships between human capital and performance and social capital and performance.     

Risk communication and social media during food safety crises: a study of stakeholders’ opinions in Ireland

Social media is a particular communication platform which has witnessed an exponential growth in use and influence in recent years, democratising the communication process, and offering risk communicators a way of putting into practice those principles which are advocated to be at the core of risk management and communication. However, little is known about stakeholders’ willingness to embrace this new form of communication in a food crisis. The current study presented an exploratory investigation of the opinions of Irish stakeholders on the position of risk communication in a crisis, with a particular focus on understanding what application social media may have. In-depth one-to-one interviews were carried out with key stakeholders holding frontline positions in managing and communicating about risk in the food sector in Ireland. The stakeholders identified risk communication as a central activity in a food safety crisis, driven by an obligation to protect both consumer health and the reputation of the Irish food sector. Stakeholders relied primarily on risk communication to disseminate information in a crisis so to educate and inform the public on a risk and to prevent confusion and alarmism; most did not explicitly value two-way risk communication in a crisis. The ability to effectively manage future crises may depend on stakeholders’ willingness to adapt to the changing communication landscape, namely – their willingness to adopt social media and use it effectively. The findings indicate that the stakeholders interviewed are appreciative of the need to engage with social media in times of a food safety crisis. However, most valued social media as a one-way channel to help spread a message and there was little reference to the interactive nature of this medium. Implications for integrating social media into crisis risk communication strategies are discussed.     

Touring the ‘comuna’: memory and transformation in Medellin,Colombia

The objective is to explore the touristification of some peripheral neighbourhoods of Medellin. The focus is on urban areas built by war-displaced populations commonly referred to as ‘comunas’ and often associated with crime and narco-traffic. Some tours generally labelled as ‘comuna tours’ have been emerging during the last three years and are largely included in the promotion of the ‘new Medellin’, focusing on its transformation from ‘the most violent to the most innovative city in the world’. Examining the role of the different stakeholders, including local community leaders, private entrepreneurs or state representatives, it will show that this practice is above all multiform and has to be analysed along with the general process of city branding ongoing in Medellin. Between the acknowledgement of past violent events and the will to look forward, competing narratives are at stake in this touristic and memorial arena.     

Farmer Brown v. Rancher Wyatt: Teaching the Coase Theorem

The Coase Theorem is a fundamental tenet of environmental economics and is taught to thousands of principles of microeconomics students each year. Its counterintuitive conclusion, that a Pareto optimal solution can result between private parties regardless of the initial allocation of property rights over a scarce resource, is difficult for students to understand. By using a mock trial that centers on a property dispute, students can be taught how the Coase Theorem works in practice with minimal preparation. The strong assumptions on which the Coase Theorem relies also can be included to show why the theorem may not hold. By using a unique, active learning technique, students will be more engaged and may have a better understanding of a difficult but seminal theory of economics.     

A decision support system to investigate dynamic last-mile distribution facilitating cargo-bikes

This work presents a decision support system to facilitate efficient urban last-mile distribution. Orders are collected and delivered by a fleet of both conventional vehicles owned by a logistics provider and cargo-bikes operated by freelancers. Additionally, micro-hubs are operated to perform transshipments between multiple vehicles. To investigate the corresponding problem setting, an agent-based simulation is developed, which uses dynamic optimisation procedures to generate and select vehicle routes and transshipment points. Experiments motivated by dynamic real-world urban restaurant delivery services investigate the impact of cargo-bikes, urban consolidation and guaranteed delivery times. Potentials are discussed and implications for successful implementations are provided. Results highlight the importance of having a sufficient number of active cargo-bikes available and benefits of incorporating consolidation strategies to guarantee timely deliveries.

The buyers’ perspective on security design: Hedge funds and convertible bond call provisions

We provide evidence that security design reflects the interplay of capital supplier and security issuer preferences. While call provisions have historically been the default option in convertible security design, only a minority of post-2005 issues are callable. Because hedge funds dominate the market for new convertibles today and because convertible arbitrage is less risky without callability, the recent diminution in the frequency of call provisions in new convertible bond issues illustrates the importance of the preferences of the suppliers of capital in security design.     

Croatia’s Dairy Sector—Can it Compete in the European Market?

Croatia is very close to meeting the requirements for becoming a member of the European Union (EU). Obviously, the agricultural sector and food processing chain are core issues within the negotiation process. This paper discusses the competitiveness of Croatia’s agro-food sector, specifically dairy products, within the EU-25 market. Two analytical methods are employed: (1) the domestic resource costs (DRC) and (2) the revealed comparative export advantage index (RXA). The DRC analysis is based on a 2007 survey of dairy farms. Primary data was complemented with trade figures from 2000 to 2007. The analyses indicate that Croatia’s dairy production is not competitive in its present structure. This lack of competitiveness at the farm level can be compensated somewhat at the processing level.
