World Market Risk, Country-Specific Risk and Expected Returns in International Stock Markets

This paper determines whether the world market risk, country-specific total risk, and country-specific idiosyncratic risk are priced in an international capital asset pricing model (ICAPM). Portfolio-level analyses, country-level cross-sectional regressions, stacked time-series, and pooled panel regressions indicate that the world market risk is not, but country-specific total and idiosyncratic risks are significantly priced in an ICAPM framework with partial integration. This result is robust to different methods for estimating risk measures, different investment horizons, and after controlling for the countries' aggregate dividend yield, earnings-to-price ratios, inflation risk, exchange rate uncertainties, aggregate volatility risk, and past return characteristics. The main findings turn out to be insensitive to the choice of one-factor vs. multifactor models used to estimate systematic and idiosyncratic risk measures.
Indirect Reciprocity in Contributions to a Peer-to-Peer Music Sharing Network - An Empirical Analysis of Individual Level Data

This study assesses the influence of indirect reciprocity on individual contribution to a peer-topeer network. We find that individuals’ level of contributions increases with number of contributors in the peer-to-peer network but decrease with number of free riders in the networks, indicating that individual contributions are reciprocal in nature. Moreover, we show that individuals have strong incentive to punish free riders and reward contributors in the peer-to-peer network. They do so through the setting of servers that allows discrimination among downloaders. When number of free riders increases, individuals are more likely to change the server settings to provide priority services to contributors and lesser services to free riders. The phenomena are consistent with findings from economic experiments which suggest that reciprocity and the ability to punish free riders could sustain contribution to pubic goods. The findings have important implications on the design and practical management of peer-to-peer networks.
Friend or Foe? The Effects of Managerial Politics on NPD Team Communication, Collaboration and Project Success

Much existing work on new product development (NPD) team integration takes an economically rational perspective, specifying appropriate systems, structures and interactions. Few studies however have explored the effects of politics on working relationships between technically trained managers (TTMs; e.g., research and development managers) and marketing managers (MMs) during NPD. Our results reveal that intra‐team politics has positive and negative effects on TTM/MM communication. This is important because communication positively influences collaboration and NPD success. Moreover, the effects of communication variables on these two outcome variables differ depending on whether one is a TTM or MM.
Cuba's Aborted Reform: Socioeconomic Effects, International Comparisons, and Transition Policies

This volume analyzes Cuban socioeconomic policies and evaluates their performance since the collapse of the Soviet Union and the socialist camp. It provides a brief historical background to the crisis and analyzes in detail the deterioration and incomplete recovery since 1990. Comparing Cuba's performance with that of other Latin American and former socialist countries, it summarizes the views of noted Cuban economists and proposes policies that architects of the Cuban transition might wish to put in place after the passing of Castro. Focusing on economic and social policies and performance during the "Special Period in Time of Peace" (1990-2004), the authors draw on an impressive array of statistics to show that in 2005 Cuba has yet to return to economic levels of the late 1980s, and the access and quality of many of the highly touted social services - education, health care, social security, housing - also have not been restored to the levels achieved prior to the economic crisis triggered by the collapse of the Soviet Union. The authors demonstrate that governmental concerns about a strengthening private sector resulting in loss of political control finally prompted the Cuban leadership to prioritize political over economic ends. Centralized economic control has been fully restored, even though it will undoubtedly result in further deterioration of economic conditions and declining standards of living.
A Directional Distance Approach Applied to Higher Education: An Analysis of Teaching‐Related Output Efficiency

This paper applies a data envelopment analysis (DEA) method to assess technical efficiency of both private and public universities in Italy. A directional distance function approach has been applied in order to handle both desirable (i.e. number of graduates) and undesirable (i.e. number of dropouts) outputs. The findings based on a panel from academic year 2003/2004 to 2007/2008 reveal the presence of interesting geographical (both by macro areas and regions) and ownership (private, public) effects. Several quality and quantity proxies have also been used in order to check whether the estimates depend on the output specification. Finally, the possible evidence of variation in the universities’ performances by subject of study has been taken into account in order to check whether the results are still consistent comparing universities within subject rather than across subjects.
Ethical investing - why not? An evaluation of financial performance of ethical indexes in comparison to conventional indexes

Title: Ethical investing - why not? An evaluation of financial performance of ethical indexes in comparison to conventional indexes. Problem : Do ethical investments perform better than conventional investments? Purpose: To evaluate whether Shariah-compliant indexes and/or socially responsible indexes can improve financial performance of an investment portfolio. Sub-problem: What kind of relationship exists between socially responsible investments and faith-based investments, represented by Shariah-compliant investments? Sub-purpose: To discover how two types of ethical investments, socially-responsible and Shariah-compliant, are related. Method: Quantitative study, covering three types of investment styles of four index families during the period from 2000 until 2011. Financial performance evaluation through the Sharpe ratio, Treynor ratio and Jensen’s alpha. Conclusions: Conventional, socially responsible, and Shariah-compliant indexes do not have any significant differences in financial performance on a global basis. However, Shariah-compliant indexes could slightly over-perform conventional and socially responsible indexes during financial downturns. In the same time socially responsible indexes were noticed to be the most volatile during the whole period of study, to compare with conventional and Shariah-compliant. Regarding relationships, high correlations were found between ethical indexes, as well as between ethical and conventional indexes.
Students' Ratings of Professors: The Teaching Style Contingency for Latino/a Professors

This article examines the influence of gender, ethnicity (Latino/a or Anglo), and teaching style (lenient or strict) on students' perceptions of professors teaching a social science course. Undergraduates read and responded to a syllabus and rated the course and the instructor on dimensions such as warmth, knowledge, and political bias. Contrary to previous research, there were no significant effects associated with professor gender. However, there were several ethnicity by teaching style interactions. Latino/a professors received either the least or most favorable marks depending on whether they presented the course with a strict or lenient teaching style, respectively. Results are discussed in terms of aversive racism and the contingent nature of evaluation for Latino/a professors.
[PI-RADS classification: structured reporting for MRI of the prostate].

PURPOSE To flesh out the ESUR guidelines for the standardized interpretation of multiparametric magnetic resonance imaging (mMRI) for the detection of prostate cancer and to present a graphic reporting scheme for improved communication of findings to urologists. MATERIALS AND METHODS The ESUR has recently published a structured reporting system for mMRI of the prostate (PI-RADS). This system involves the use of 5-point Likert scales for grading the findings obtained with different MRI techniques. The mMRI includes T2-weighted MRI, diffusion-weighted imaging, dynamic contrast-enhanced MRI, and MR spectroscopy. In a first step, the fundamentals of technical implementation were determined by consensus, taking into account in particular the German-speaking community. Then, representative images were selected by consensus on the basis of examinations of the three institutions. In addition, scoring intervals for an aggregated PI-RADS score were determined in consensus. RESULTS The multiparametric methods were discussed critically with regard to implementation and the current status. Criteria used for grading mMRI findings with the PI-RADS classification were concretized by succinct examples. Using the consensus table for aggregated scoring in a clinical setting, a diagnosis of suspected prostate cancer should be made if the PI-RADS score is 4 or higher (≥ 10 points if 3 techniques are used or ≥ 13 points if 4 techniques are used). Finally, a graphic scheme was developed for communicating mMRI prostate findings. CONCLUSION Structured reporting according to the ESUR guidelines contributes to quality assurance by standardizing prostate mMRI, and it facilities the communication of findings to urologists.
Physical Implementation and Evaluation of Ad Hoc Network Routing Protocols using Unmodified Simulation Models

Simulation and physical implementation are both valuable tools in evaluating ad hoc network routing protocols, but neither alone is sufficient. In this paper, we present the design and implementation of a new system that allows existing simulation models of ad hoc network routing protocols to be used —without modification —to create a physical implementation of the same protocol. We have evaluated the simplicity and portability of our approach across multiple protocols and multiple operating systems through example implementations in our architecture of the DSR and AODV routing protocols in FreeBSD and Linux using the existing, unmodified ns-2 simulation models. We also illustrate the ability of the resulting protocol implementations to handle real, demanding applications by presenting a demonstration of this DSR implementation transmitting real-time video over a multihop mobile ad hoc network including mobile robots being remotely operated based on the transmitted video stream.
No-Reflow Phenomenon in Central Retinal Artery Occlusion: Incidence, Risk Factors, and Clinical Implications

Purpose To investigate the incidence and risk factors of the no-reflow phenomenon in central retinal artery occlusion (CRAO) patients and to determine its effects on visual and anatomic outcomes. Methods In 102 eyes with CRAO in which arterial recanalization was obtained within 1 week from baseline, fluorescein angiography images obtained at baseline and 1 week were retrospectively reviewed. The no-reflow phenomenon in the retina was defined as macular capillary nonperfusion following arterial recanalization on fluorescein angiographs. We investigated the incidence and risk factors for the no-reflow phenomenon and compared the anatomical and visual outcomes between eyes with and without the phenomenon. Results Among the 102 CRAO eyes with arterial recanalization, 39 exhibited the no-reflow phenomenon, resulting in an incidence of 38.2%. The incidence among the eyes with treatment-induced and spontaneous recanalization was 43.4% and 15.8%, respectively, and it increased with the CRAO stage. CRAO stage and increased central macular thickness were risk factors for the phenomenon, with an odds ratio of 4.47 [95% confidence interval (CI), 1.19–16.8; P = 0.027] and 1.69 (95% CI, 1.12–2.55; P = 0.012) per 100-μm increase, respectively. The visual outcome was significantly poorer and retinal atrophy and photoreceptor disruption was greater in eyes with the no-reflow phenomenon than in those without. Conclusions The no-reflow phenomenon may occur after arterial recanalization in approximately one-third of CRAO patients and can affect anatomical and visual outcomes. This phenomenon may provide an additional explanation regarding the permanent retinal damage and vision loss in eyes with CRAO.
Essays on the limits of borrowing

The aim of this PhD dissertation is to provide new insights about the limits of borrowing. It includes four essays which provide theoretical, methodological and empirical results. The first chapter contributes to the theory of limits of borrowing by a study of lender of last resort (LOLR) in an original model. The second chapter contributes to methodology by introducing a new approach to test and measure the limits of borrowing econometrically. It also contributes to the empirical understanding of the limits of borrowing by applying the new approach to test the cyclical behavior and the effects of regulation on the limits of borrowing. The third chapter contributes to our empirical understanding of the effect of limits of borrowing on consumption. The fourth chapter yields new insight about the effect of bank ownership on the limits of borrowing during a financial crisis.
Head Cooling for Neonatal Encephalopathy: The State of the Art

The possibility that hypothermia started during or after resuscitation at birth might reduce brain damage and cerebral palsy has tantalized clinicians for a long time. The key insight was that transient severe hypoxia-ischemia can precipitate a complex biochemical cascade leading to delayed neuronal loss. There is now strong experimental and clinical evidence that mild to moderate cooling can interrupt this cascade, and improve the number of infants surviving without disability in the medium term. The key remaining issues are to finding better ways of identifying babies who are most likely to benefit, to define the optimal mode and conditions of hypothermia and to find ways to further improve the effectiveness of treatment.
Sport marketing in Cyprus - the dynamics of the sport sponsorship context: emergence, development and management practices in the football industry

This thesis investigates the underlying mechanisms and processes that shape sport sponsorship in Cyprus. A systematic review of the international sport sponsorship literature (1980-2009) is undertaken and used as the guide for the qualitative empirical study concentrating on football sponsorship activity undertaken in Cyprus as a developing sport sponsorship market. The systematic review reveals sponsorship management structures, practices, tendencies, and models adopted at a range of national settings, and discloses contrasts that exist in different contexts. The findings of the systematic review highlight the management practices employed by sponsors, such as their motives, decision-making practices, activation and leveraging initiatives, objectives, and evaluation processes. With regard to the empirical investigation, sponsorship activity is viewed and interpreted within the broader social and cultural context in which it takes place. The analysis of the findings is informed by critical realism paradigm, so that the underlying causal mechanisms and structures shaping (or influencing) sponsorship activity in Cyprus are identified and discussed. Specifically, the findings of study, which focused on the top division of the national professional league, revealed the existence of a sponsorship continuum involving four significantly different sponsorship approaches, ranging from purely philanthropic to heavily rational and commercial. Interestingly, the study revealed the interdependence of global and local processes within the sponsorship-related practices, suggesting that sponsorship arrangements in this specific context are marked culturally by processes of glocalisation. Such processes appeared to be vividly expressed in sponsorship-related projects in Cyprus, and involved an amalgamation of several local and cultural factors such as a strong prevalence of localism, nationalism, political clientelism, and reliance on personal relations. Community pressures seemed to have a central role in sponsorship related decision-making, whilst sponsorship activity appeared also to be influenced by the structure of the sponsors industry, the organisational structure and corporate culture, as well as by the structure and local specificity of the football market in Cyprus. More specifically, competitive imbalance of the national league, politicisation of football, the level of competition within a particular industry, and centrality of authority and control (both organisational and cultural), are additional factors that appeared to impact sponsorship activity in the specific market.
Ambulatory Blood Pressure Monitoring and Organ Damage

Several papers have suggested that 24-hour average blood pressure (BP) is superior to office BP in relation to hypertension target organ damage. This review article will specifically address the evidence provided in this regard by either cross-sectional or longitudinal studies. It will also critically discuss the available data supporting the concept that not only 24-hour average BP values, but also specific BP patterns occurring within the 24 hours may have clinical relevance. This is the case for daytime versus nighttime BP, the day/night BP difference, the morning BP rise, and overall BP variability.
Low-Wage Work in the United Kingdom

The United Kingdom's labor market policies place it in a kind of institutional middle ground between the United States and continental Europe. Low pay grew sharply between the late 1970s and the mid-1990s, in large part due to the decline of unions and collective bargaining and the removal of protections for the low paid. The changes instituted by Tony Blair's New Labour government since 1997, including the introduction of the National Minimum Wage, halted the growth in low pay but have not reversed it. Low-Wage Work in the United Kingdom explains why the current level of low-paying work remains one of the highest in Europe. The authors argue that the failure to deal with low pay reflects a policy approach which stressed reducing poverty, but also centers on the importance of moving people off benefits and into work, even at low wages. The U.K. government has introduced a version of the U.S. welfare to work policies and continues to stress the importance of a highly flexible and competitive labor market. A central policy theme has been that education and training can empower people to both enter work and to move into better paying jobs. The case study research reveals the endemic nature of low paid work and the difficulties workers face in escaping from the bottom end of the jobs ladder. However, compared to the United States, low paid workers in the United Kingdom do benefit from in-work social security benefits, targeted predominately at those with children, and entitlements to non-pay benefits such as annual leave, maternity and sick pay, and crucially, access to state-funded health care. Low-Wage Work in the United Kingdom skillfully illustrates the way that the interactions between government policies, labor market institutions, and the economy have ensured that low pay remains a persistent problem within the United Kingdom.
Very low-metallicity massive stars: - Pre-SN evolution models and primary nitrogen production

Context. Precise measurements of the surface abundances of extremely low-metallicity stars have recently been obtained, and they provide new constraints for the stellar evolution models. Aims. Stellar evolution models were computed in order to explain the surface abundances observed, in particular of nitrogen. Methods. Two series of models were computed. The first series consists of 20 $M_\odot$ models with varying initial metallicity ($Z=0.02$ down to $Z=10^{-8}$) and rotation ($\rm \upsilon_{ini}=0{-}600$ km s -1 ). The second one consists of models with an initial metallicity of $Z=10^{-8}$, masses between 9 and 85 $M_\odot$, and fast initial rotation velocities ($\rm \upsilon_{ini}=600{-}800$ km s -1 ). Results. The most interesting models are those with $Z=10^{-8}$ ([ Fe/H$]\sim-6.6$). In the course of helium burning, carbon and oxygen are mixed into the hydrogen-burning shell. This boosts the importance of the shell and causes a reduction of the CO core mass. Later in the evolution, the hydrogen shell deepens and produces a large amount of primary nitrogen. For the most massive models ($M\ga 60$ $M_\odot$), significant mass loss occurs during the red supergiant stage. This mass loss is due to the surface enrichment in CNO elements via rotational and convective mixing. The 85 $M_\odot$ model ends up as a WO-type Wolf-Rayet star. Therefore the models predict SNe of type Ic and possibly long and soft GRBs at very low metallicities. The rotating 20 $M_\odot$ models can best reproduce the observed CNO abundances at the surface of extremely metal-poor (EMP) stars and the metallicity trends when their angular momentum content is the same as at solar metallicity (and therefore have an increasing surface velocity with decreasing metallicity). The wind of the massive-star models can reproduce the CNO abundances of the most metal-poor carbon-rich star known to date, HE1327-2326.
Development and Evaluation of a Quantitative PCR Assay Targeting Sandhill Crane (Grus canadensis) Fecal Pollution

ABSTRACT While the microbial water quality in the Platte River is seasonally impacted by excreta from migrating cranes, there are no methods available to study crane fecal contamination. Here we characterized microbial populations in crane feces using phylogenetic analysis of 16S rRNA gene fecal clone libraries. Using these sequences, a novel crane quantitative PCR (Crane1) assay was developed, and its applicability as a microbial source tracking (MST) assay was evaluated by determining its host specificity and detection ability in environmental waters. Bacteria from crane excreta were dominated by bacilli and proteobacteria, with a notable paucity of sequences homologous to Bacteroidetes and Clostridia. The Crane1 marker targeted a dominant clade of unclassified Lactobacillales sequences closely related to Catellicoccus marimammalium. The host distribution of the Crane1 marker was relatively high, being positive for 69% (66/96) of the crane excreta samples tested. The assay also showed high host specificity, with 95% of the nontarget fecal samples (i.e., n = 553; 20 different free-range hosts) being negative. Of the presumed crane-impacted water samples (n = 16), 88% were positive for the Crane1 assay, whereas none of the water samples not impacted by cranes were positive (n = 165). Bayesian statistical models of the Crane1 MST marker demonstrated high confidence in detecting true-positive signals and a low probability of false-negative signals from environmental water samples. Altogether, these data suggest that the newly developed marker could be used in environmental monitoring studies to study crane fecal pollution dynamics.
