From waste to hydrogen: An optimal design of energy production and distribution network

This paper focuses on evaluating the economic potential and infrastructure requirements of hydrogen production from agricultural residues, a representative green energy pathway. A mixed-integer nonlinear programming model is constructed for finding the most efficient and economical configuration of the whole pathway. Using northern California case studies, we found that hydrogen from agricultural wastes can be delivered at costs similar to producing hydrogen from natural gas, a non-renewable energy source. The potential impact of this energy pathway on local freight transport is also discussed depending on the choice of hydrogen delivery mode.     

A Credible Path for Ending Too Big to Fail

The high degree of concentration in the U.S. financial system has been intensified in the wake of the 2007–09 financial crisis. Implicit government support of banks that are deemed “too big to fail” has resulted in excessive risk taking and a focus on short-term rewards rather than long-term performance. This paper proposes a three-step plan to limit the federal safety net to commercial depository institutions and to restructure institutions so that no one institution poses systemic risk in the event of failure and that the largest banks face the same kind of risks of closure and market risk as the smallest.     

Consciousness at Work: A Review of Some Important Values,Discussed from a Buddhist Perspective

This article reviews the element of consciousness from a Buddhist and a non-Buddhist (Western) perspective. Within the Buddhist perspective, two practices toward attaining expanded and purified consciousness will be included: the Seven-Point Mind Training and Vipassana. Within the Western perspective, David Hawkins’ works on consciousness will be used as a main guide. In addition, a number of important concepts that contribute to expanded and purified consciousness will be presented. Among these concepts are impermanence, karma, non-harming (ahimsa), ethics, kindness and compassion, mindfulness, right livelihood, charity, interdependence, wholesome view, collaboration, and fairness. This article may be of use to students and workforce members who consider a transdisciplinary approach on human wellbeing in personal and professional environments.     

Tracking a changing copula

A copula models the relationships between variables independently of their marginal distributions. When the variables are time series, the copula may change over time. Recursive procedures based on indicator variables are proposed for tracking these changes over time. Estimation of the unknown parameters is by maximum likelihood. When the marginal distributions change, pre-filtering is necessary before constructing the indicator variables on which the recursions are based. This entails estimating time-varying quantiles and a simple method based on time-varying histograms is proposed. The techniques are applied to the Hong Kong and Korean stock market indices. Some interesting and unexpected movements are detected, particularly after the attack on the Hong Kong dollar in 1997.     

Factors influencing repeat visits to a destination: The influence of group composition

This paper is an analysis of the likelihood for repeat visits to a sun and sand destination by tourists. For this purpose, an empirical study was conducted using tourists who had visited the destination. The analysis took into account the travelling group composition. The results showed that, for the total tourist sample, overall satisfaction had the biggest influence on the decision of whether to revisit a destination, while the least important influence was the tourist's perceived image. These influences varied, however, when different travelling group compositions were considered. The results are of vital importance in tourism management policies, because they can contribute to the better design and development of tourism promotion strategies.     

Socially Responsible Investing: An Investor Perspective

Given the growing importance of Socially Responsible Investing (SRI), it is surprising that there is no consensus of what the term SRI means to an investor. Further, most studies of this question rely solely on the views of investors who already invest in SRI funds. Our study surveys a unique pool of approximately 5,000 investors that contains both investors who have used SRI criteria in investment decisions and those who have not, and involves a broad array of criteria associated with SR investing. Our findings offer new insight into the SRI debate. For both sets of investors, environmental and sustainability issues dominate as the major category associated with SR investing. We find strong agreement in the ranking of the relative importance of various SRI factors despite differences between these two groups in their opinion of their overall importance. We also find that investors prefer to consider the SRI question in more holistic terms rather than using the exclusionary format favored by most SRI funds. Investors seem to prefer to reward firms who display overall positive social behavior rather than to exclude firms on the basis of certain products or practices. These findings can help providers of SR investment vehicles to improve the SRI products that they offer to the general investor, thus both encouraging the initial adoption of SR criteria by investors and increasing overall investment in SR choices.     

Beyond the Toledo agreement: the intergenerational impact of the Spanish Pension Reform

The paper examines the intergenerational impact of the Spanish public pension system after the 1997 Pension Reform Act. Within a Generational Accounting framework, we find that the new legal setting could leave future generations with liabilities as high as 176% of 1996 GDP. Hence, we analyse the impact of alternative reforms. Holding the pay-as-you-go setting, a further improvement to tax-benefit linkage in line with the Toledo Agreement proposals is shown to yield an intergenerationally more balanced outcome, than an increase in the retirement age or an expansion of public subsidies financed through indirect taxes. Finally, a move toward a partially funded pension system which restores the intergenerational balance is simulated.     

Technological experience and the technology adoption decisions in small manufacturing firms

This paper investigates changes in factors bearing on technology adoption decisions in small manufacturing firms. It is hypothesized that, as a firm's experience with technology increases and its technological capabilities grow, the decision process is gradually modified and puts more weight on those factors which are more closely related to the true potential of the technology. An empirical study shows the more innovative firms to have an outward orientation dominated by clients and suppliers, and to pay more attention to the added flexibility brought about by new technology. It is also shown that functional groups within the company play a more important role in the decision-making process.     

The Risk Exposure of Emerging Equity Markets

The low correlation between returns in emerging equity marketsand industrial equity markets implies that the global investorwould benefit from diversification in emerging markets. Thisarticle explores the sensitivity of the emerging-market returnsto measures of global economic risk. When these traditionalmeasures of risk are used, the emerging markets have littleor no sensitivity. This finding is consistent with these markets'being segmented from world capital markets. However, the correlationbetween the emerging-market returns and the risk factors appearsto be changing over time.
