Approaches towards a generic methodology for storage of hazardous energy carriers and waste products

Energy carriers – either conventional or ‘new’ ones – have to be provided in large amounts to meet the requirements of permanent availability and reliable supply of electricity. Depending on their state of aggregation, energy carriers are either stored in large masses (if solid or liquid) or at elevated pressures (if gaseous). Both impose the hazard of large-scale fire, in the latter case additionally the danger of explosion or unintended release. Very similar hazards occur for wastes. Solid wastes are present in large masses and only a small part is recycled. Most of the solid wastes are used in energy conversion. The main gaseous waste is CO₂. During capturing also the hazard of unintended release exists. In this article, existing approaches for safe storage and fire prevention are discussed and a generic methodology is outlined. This methodology consists of the following steps:

? gaining knowledge about the behaviour of the material stored (reactivity, thermal stability, etc.),

? assessing the environmental conditions for the storage site (neighbourhood, safety distances, etc.),

? assessment of prospective consequences of an incident and

? development of individual loss prevention conceptions.

All steps require both experimental testing and theoretical considerations about accident scenarios as integral parts of the methodology.     

The Institutional Foundations of Public Policy: A Transactions Approach with Application to Argentina

Public policies are the outcomes of complex intertemporal exchangesamong politicians. The political institutions of a country constitutethe framework within which these transactions are accomplished.We develop a transactions theory to understand the ways in whichpolitical institutions affect the transactions that politicalactors are able to undertake, and hence the quality of the policiesthat emerge. We argue that Argentina is a case in which thefunctioning of political institutions has inhibited the capacityto undertake efficient intertemporal political exchanges. Weuse positive political theory and transaction cost economicsto explain the workings of Argentine political institutionsand to show how their operation gives rise to low-quality policies.     

Value Creation in the Insurance Industry

Using the insights of current research in corporate finance and financial institutions, the authors briefly present a consistent economic framework for looking at insurance. Shareholders of insurance companies provide risk capital that is invested in financial assets and therefore earns the market return of the assets it is invested in. However, due to the legal and fiscal environment insurance companies are in, they have a competitive disadvantage at investing, and this gives rise to frictional capital costs. The core competence of insurers is in managing the size of these frictional capital costs. Insurers must ensure that they can sell insurance for a price in excess of what they need to produce the cover they sell and compensate the incurred frictional costs on risk capital. It is through the ability to do so that insurers create shareholder value.     

Rate of Return Regulation: The Case of Spanish Ports

An original model is put forward in this article to explain and consider the behavior of some of the most important public services in Spain. The cost function approach and the input distance function approach are used to estimate the existence of overcapitalization as a result of rate of return regulation. The results show that overcapitalization generated by this regulation is too significant not to be taken into account.     

Uncertain availability,spatial location and regulation: An application to the airline industry

This paper presents an analysis of industries characterized by both uncertain availability and spatial location of the product. The analyis is applied to the US airline industry and is used to analyze the differential effect of price regulation on different markets and firms. From this analysis we obtain insights into which firms and markets may have benefited most from the deregulation of the industry in 1978. Previous works on the regulation of the airline industry implicitly assume that markets have the same demand structure. If airline services are of homogeneous quality, men we do not expect the unregulated solution to depend on demand structures. If on the other hand airline services vary in their quality component, then different markets may have different equilibrium price-quality combinations depending on the characteristics of demand. This paper explores the implication of different demand structures on the impact of (de)regulation.     

Microenterprise Dynamics in Developing Countries: How Similar are They to Those in the Industrialized World? Evidence from Mexico

A rich panel data set from Mexico is used to study the patternsof entry, exit, and growth of microenterprises and to comparethese with the findings of the mainstream theoretical and empiricalwork on firm dynamics. The Mexican self-employment sector ismuch larger than its counterpart in the United States, whichis reflected in higher unconditional rates of entry into thesector. The evidence for Mexico points to the significant presenceof well-performing salaried workers among the likely entrantsinto self-employment, as opposed to the higher incidence ofpoorer wageworkers among the entrants into the U.S. self-employmentsector. Despite these differences, however, the patterns ofentry, survival, and growth with respect to age, education,and many other covariates are very similar in Mexico and theUnited States. These strong similarities suggest that mainstreammodels of worker decisions and firm behavior are useful guidesfor policymaking for the developing-country microenterprisesector. Furthermore, they suggest that, as a first approximation,the developing-country microenterprise should probably be viewedas they are in the advanced countries as offering potentiallydesirable job opportunities to low-productivity workers.     

The double-edged sword of purpose-driven behavior in sustainable venturing

This paper examines the relationship between purpose and purposeful organizing and how such arrangements influence the entrepreneurial journey as sustainable ventures move from idea to markets. We leverage an iterative multi-stage process-tracing design to understand the mechanisms whereby 14 different B Corp certified organizations embed purpose before, during and after the certification process. Our analyses reveal three types of venture paths for purpose-driven entrepreneurs, which are shaped by distinct imprinting sequences with three critical sensitive windows playing a pivotal role: the definition of scope of purpose, timing of purpose formalization through B Corp Certification and shifts in the source of feedback. Different imprinters occurring within the critical sensitive windows shape particular imprinting sequences triggering situations of both productive and counterproductive path development. Our results challenge the assumed linear relationship between purpose and purposeful organizing and more specifically the belief that seeking (purposeful) B Corp certification at firm foundation is necessarily productive for society and for the ventures themselves regardless of when the certification is achieved.     

Trauma epidemiology in Puerto Rico: in-hospital morbidity and mortality from 2002 to 2011

This study aimed to describe the distribution of injury mechanisms and to assess the impact of those mechanisms on the morbidity and mortality of trauma. All patients admitted to Puerto Rico Trauma Hospital (2002–2011) for road-traffic collisions (RTCs, 5,371), gunshot wounds (GSWs, 2,946), falls (2,319), pedestrian accidents (1,652), and stab wounds (SWs, 1,073) were selected. Gunshot victims were 1.19 (95%CI: 1.07–1.33) times as likely as road-traffic victims to have an ISS ≥25. Pedestrians were 1.76 (95%CI: 1.49–2.09) times more likely to have a GCS ≤8 than road-traffic victims were. The risk of dying was 2.64 (95%CI: 2.20–3.16) times higher for gunshot victims and 1.51 (95%CI: 1.23–1.86) times higher for pedestrians compared to patients who had had RTCs. Gunshot victims and pedestrians had the worst clinical outcomes. Accordingly, these patients should receive the most aggressive clinical management. Furthermore, it is imperative to develop public health campaigns on trauma prevention.
