Policy and regulatory framework for renewable energy and energy efficiency development in Ghana

What external support is needed to assist Ghana's domestic policies to overcome domestic barriers and increase the scope, scale and speed of adoption of renewable energy and energy efficiency technologies? Although Ghana has a well-established regulatory environment and institutional set-up, international cooperation and support are required to leverage domestic policy and create an enabling environment to accelerate the transition to affordable and reliable renewable energy. International support can also be used to enhance the activities of the Energy Foundation and energy service companies (ESCOs) as well as to increase the adoption of energy efficiency technologies through residential and industrial demand-side management (DSM) activities. Policy relevance: Despite domestic and international financial incentives, barriers from the regulatory framework and from conventional practice prevent the utilization of renewable resources in both grid-connected and off-grid applications. Tackling these barriers requires both government commitment towards a comprehensive strategy and support from different stakeholders to explore viable solutions. Such action can be supported, but not replaced, with international support for capacity building, technical assistance and finance. Experience from Ghana points to some success for such a strategy for energy efficiency measures but also highlights the importance of domestic and international structures that ensure continuity of an institution with sufficient resources for programme and project execution.
Society and HRM in China

In this contribution to the Symposium, we shall look at the relationship between Society and Human Resource Management (HRM) not only in its general context but also in its Chinese setting. Our argument is that there needs to be a minimum degree of consonance between the two – if HRM is to be sufficiently underpinned by social reality. A review of how Chinese society and its organizations have changed in the last half-century and how its economy and management, including HRM, have been transformed since the post-1978 economic reforms is then set out. Our main findings are that much of the research published in this Symposium if no doubt relatively ‘representative’ of the social changes found in PRC today is, however, mostly ‘cross-sectional’ and ‘specialized’. What is missing are studies we might judge to be both ‘longitudinal’ and ’broad’ in scope. We conclude by suggesting that it is only in a wider framework that ‘people-management’ can be best understood, whether we are looking at theory or practice, both in general and vis-à-vis the PRC.
Options, Futures, and Other Derivatives in Russia: An Overview

This work provides a descriptive overview of Russian markets for financial derivatives. Available figures for the exchange-traded and over-the-counter-traded derivatives in Russia show that the Russian derivatives markets experienced enormous growth rates since the financial crisis in 1998. Starting from a very low level, turnover of exchange-traded derivatives in Russia rose from 2000 to 2006 on average 168 percent per year and reached a total turnover of EUR 102 billion in 2006. Among futures, equity futures, followed by currency futures, are the most traded exchange-traded derivatives in Russia. Turnover of exchange-traded derivatives on interest rates, bonds or even commodities represent only a very small fraction of the total turnover. Available figures for the Russian OTC foreign exchange derivatives market suggest for the period between April 2004 and 2007 an annual turnover growth rate of 47 percent. Foreign exchange swaps in RUR against USD and in USD against EUR and other currencies were the most popular OTC foreign exchange derivatives in April 2004 and 2007.
Principal component models for generating large GARCH covariance matrices

type="main" xml:lang="en"> The implementation of multivariate GARCH models in more than a few dimensions is extremely difficult: because the model has many parameters, the likelihood function becomes very flat, and consequently the optimization of the likelihood becomes practicably impossible. There is simply no way that full multivariate GARCH models can be used to estimate directly the very large covariance matrices that are required to net all the risks in a large trading book. This paper begins by describing the principal component GARCH or ‘orthogonal GARCH’ (O-GARCH) model for generating large GARCH covariance matrices that was first introduced in Alexander and Chibumba (1996) and subsequently developed in Alexander (2000, 2001b). The O-GARCH model is an accurate and efficient method for generating large covariance matrices that only requires the estimation of univariate GARCH models. Hence, it has many practical advantages, for example in value–at–risk models. It works best in highly correlated systems, such as term structures. The purpose of this paper is to show that, if sufficient care is taken with the initial calibration of the model, equities and foreign exchange rates can also be included in one large covariance matrix. Simple conditions for the final covariance matrix to be positive semi-definite are derived. (J.E.L.: C32, C53, G19, G21, G28).
The Influence of Price Discount versus Bonus Pack on the Preference for Virtue and Vice Foods

The authors find that consumers prefer a bonus pack to a price discount for virtue foods but they prefer a price discount to a bonus pack for vice foods. Prior research has shown that, all else being equal, consumers prefer bonus packs to price discounts. The authors propose that this preference does not hold for vice food, because consumers cannot generate good justifications for buying such food when a bonus pack is offered because this would mean consuming more of the vice. However, a price discount on a vice food can be justified because it acts as a guilt-mitigating mechanism. For virtue foods, the absence of both anticipated postconsumption guilt and the resultant need to justify leads consumers to prefer a bonus pack to a price discount. The authors demonstrate the proposed effect and test its underlying process across five experiments.
What’s in a name? Intolerance of uncertainty, other uncertainty-relevant constructs, and their differential relations to worry and generalized anxiety disorder*

Abstract A number of studies have examined the association of intolerance of uncertainty (IU) to trait worry and generalized anxiety disorder (GAD). However, few studies have examined the extent of overlap between IU and other psychological constructs that bear conceptual resemblance to IU, despite the fact that IU-type constructs have been discussed and examined extensively within psychology and other disciplines. The present study investigated (1) the associations of IU, trait worry, and GAD status to a negative risk orientation, trait curiosity, indecisiveness, perceived constraints, self-oriented and socially prescribed perfectionism, intolerance of ambiguity, the need for predictability, and the need for order and structure and (2) whether IU is a unique correlate of trait worry and of the presence versus absence of Probable GAD, when overlap with other uncertainty-relevant constructs is accounted for. N = 255 adults completed self-report measures of the aforementioned constructs. Each of the constructs was significantly associated with IU. Only IU, and a subset of the other uncertainty-relevant constructs were correlated with trait worry or distinguished the Probable GAD group from the Non-GAD group. IU was the strongest unique correlate of trait worry and of the presence versus absence of Probable GAD. Indecisiveness, self-oriented perfectionism and the need for predictability were also unique correlates of trait worry or GAD status. Implications of the findings are discussed, in particular as they pertain to the definition, conceptualization, and cognitive-behavioral treatment of IU in GAD.
Should Higher Education Subsidies Depend on Parental Income

In many countries, student grants, tuition fees, and subsidized loans depend on parental income. This paper examines the efficiency and distributional effects of such conditioning, and assesses whether it is optimal practice when the government wants to reduce after-tax income inequality in the most efficient manner. Increasing the mean level of education among the work-force compresses wage differentials by level of education and thereby the pre-tax income distribution. Hence, subsidizing education may be part of an optimal redistribution policy. However, education subsidies mainly benefit high-ability students, limiting their redistributive virtues. Conditioning education subsidies on parental income may enable the government to reduce inframarginal subsidies, mainly benefiting high-ability students, while preserving the marginal subsidy, and thus the favourable effect on the mean education level which leads to wage compression.
Ingestion and killing of Listeria monocytogenes by blood and milk phagocytes from mastitic and normal cattle

Human listeriosis resulting from consumption of listeria-contaminated dairy products is emerging as a significant public health concern. There is a need to understand better the processes involved in the pathogenesis of Listeria monocytogenes-induced bovine mastitis. In the present report, we describe the results of the in vitro interaction of L. monocytogenes with bovine blood and milk leukocytes. Induction of an experimental L. monocytogenes mastitis resulted in a rapid and dramatic increase in neutrophils in the milk of infected cows. Blood neutrophils and mononuclear cells and milk leukocytes from listeria-infected and uninfected cows readily ingested L. monocytogenes in the presence of serum opsonins. These leukocytes also killed a portion of the ingested listeriae. Ingestion of listeriae evoked a vigorous chemiluminescence response by blood neutrophils and a relatively weak response by blood mononuclear cells. Ingestion, killing, and chemiluminescence by milk leukocytes were directly related to the percentage of neutrophils that were present. Blood neutrophils from healthy donor cattle ingested and killed L. monocytogenes when leukocyte-depleted milk and whey from mastitic cows were the sole sources of opsonins, although fewer listeriae were ingested than when normal bovine serum was present. These results indicate that bovine blood and milk phagocytes, like blood and inflammatory phagocytes from other mammalian species, can ingest and kill L. monocytogenes in vitro.
Human Development Index-like Small Area Estimates for Africa Computed from IPUMS-International Integrated Census Microdata

Abstract This paper analyzes 24 African census samples from 13 countries available via the African Integrated Census MicroData website to illustrate how microdata may be used to assess development and pinpoint basic human needs at local administrative levels over time. We calculate a Human Development Index-like measure for small administrative areas, where much of the responsibility lies for executing policies related to health, education and general well-being. The methodological proposals introduced in this paper are particularly pertinent for the case of Africa. While it is true that data for much of Africa is not appropriate for economic growth rates or per-capita income estimates, the analysis in this paper demonstrates that they are good enough for many other purposes. Indeed, a major aggravating problem that contributes to the “African statistical tragedy” is the lack of accessibility to existing census microdata. This paper aims to illustrate the usefulness of census microdata—which are vastly under-utilized in Africa—and hopefully contribute to make them more transparent and freely accessible.
Running on the spot? A review of twenty years of research on the management of human resources in comparative and international perspective

Research using a comparative and international perspective on the management of human resources is examined, drawing on articles published in leading human resource management, management/organizational behaviour and related social science journals between 1977 and 1997. In total a little under 2 per cent of the articles under review focused on the management of human resources in a comparative and international perspective. The largest group of these articles was comparative in nature (44 per cent), followed by those with an international perspective (35 per cent). A smaller number adopted a combined approach (17 per cent) and a few were separately classified as foreign national studies (4 per cent). Over time, there has been some progress made in terms of the number of articles published and the scope of topics covered. However, many of the articles displayed similar shortcomings to those noted in earlier reviews of cross-national management/organization studies: in particular, an over-reliance on a sma.
Evaluation of an Urban Tourism Destination

Abstract Using the Tourist City model, this study evaluates Tel Aviv's tourism product and visitor satisfaction and asks three major questions. What tourism components does the city offer? How do tourists relate to these components? And what differences, if any, emerged in the responses of the different visitor groups? This article employs two primary research tools: objective examination and structured interviews (n = 199). Respondents were classified into four tourist groups according to visitor motivation: (1) vacation, (2) business, (3) culture, (4) visiting friends and relatives (VFR). The findings indicate that the tourist and VFR groups experienced higher levels of satisfaction than business and culture visitors. Tel Aviv's strengths were its beach and leisure components, while its weaknesses related to the city's physical aspects: transportation, cleanliness, architecture, and accommodation. Tel Aviv possesses a sufficient quantity of diverse attractions and has the potential to attract and satisfy not only VFR tourists and vacation tourists, but also ‘touring’ and business tourists. To attract all four tourist groups, the industry must focus more on secondary products and internal accessibility.
EXACT AND SUPERLATIVE WELFARE CHANGE INDICATORS

An exact welfare change indicator is defined to be a known function of the price and quantity data for two periods (for a utility maximizing consumer) which is exactly equal to the Hicksian equivalent variation. A welfare change indicator is termed superlative if it is exactly equal to the equivalent variation for an expenditure function that has a second-order approximation property. The paper exhibits a number of superlative welfare change indicators, and also reviews the earlier attempts of J. R. Hicks and M. L. Weitzman to obtain equivalent variation measures that had a second-order approximation property. Copyright 1992 by Oxford University Press.
Timing-Anomaly Free Dynamic Scheduling of Task-Based Parallel Applications

Multicore architectures can provide high predictable performance through parallel processing. Unfortunately, computing the makespan of parallel applications is overly pessimistic either due to load imbalance issues plaguing static scheduling methods or due to timing anomalies plaguing dynamic scheduling methods. This paper contributes with an anomaly-free dynamic scheduling method, called Lazy, which is non-preemptive and non-greedy in the sense that some ready tasks may not be dispatched for execution even if some processors are idle. Assuming parallel applications using contemporary taskbased parallel programming models, such as OpenMP, the general idea of Lazy is to avoid timing anomalies by assigning fixed priorities to the tasks and then dispatch selective highestpriority ready tasks for execution at each scheduling point. We formally prove that Lazy is timing-anomaly free. Unlike all the commonly-used dynamic schedulers like breadth-first and depth-first schedulers (e.g., CilkPlus) that rely on analytical approaches to determine an upper bound on the makespan of parallel application, a safe makespan of a parallel application is computed by simulating Lazy. Our experimental results show that the makespan computed by simulating Lazy is much tighter and scales better as demonstrated by four parallel benchmarks from a task-parallel benchmark suite in comparison to the state-of-the-art.
IN VITRO AND IN VIVO ENCYSTMENT OF THE CERCARIAE OF ECHINOSTOMA CAPRONI

In vitro and in vivo studies were conducted on the cercariae of Echinostoma caproni. Of the 15 media tried, 2 resulted in effective in vitro encystment in petri dish cultures maintained at 23 ± 1 C. They were a Locke's–artificial springwater (ASW) (1:1) medium (67% encystment) and a Biomphalaria glabrata embryonic cell line medium (23% encystment). To obtain large numbers of in vitro–formed cysts, finger bowl cultures containing 40 ml of the Locke's–ASW (1:1) medium were used at 23 ± 1 C. Of 3,000 cercariae tested, 1,890 (63%) were encysted in this medium by 48 hr. Most of these cysts looked similar to those formed in vivo, although some showed abnormalities in the outer cyst wall and other malformations. A total of 200 in vitro–formed cysts treated in an alkaline trypsin–bile salts (TB) medium for 2 hr at 41 C showed 94% excystation. In vitro–formed cysts fed to mice produced ovigerous adults within 2 wk postinfection (PI). Eggs from these worms gave rise to miracidia that produced patent intramolluscan infections in B. glabrata snails. In vivo encystment was studied in lab-raised juvenile Helisoma trivolvis (Colorado strain) snails, 1–3 mm in shell diameter. From 6 to 24 hr PI, 93–100% of the cercariae were recovered as metacercarial cysts in the snail tissue. Treatment of these cysts in the TB medium resulted in 96% excystation within 2 hr at 41 C.
Human Cytomegalovirus-Encoded US2 Differentially Affects Surface Expression of MHC Class I Locus Products and Targets Membrane-Bound, but Not Soluble HLA-G1 for Degradation 1

Human CMV (HCMV) can elude CTL as well as NK cells by modulating surface expression of MHC class I molecules. This strategy would be most efficient if the virus would selectively down-regulate viral Ag-presenting alleles, while at the same time preserving other alleles to act as inhibitors of NK cell activation. We focused on the HCMV unique short (US) region encoded protein US2, which binds to newly synthesized MHC class I H chains and supports their dislocation to the cytosol for subsequent degradation by proteasomes. We studied the effect of US2 on surface expression of individual class I locus products using flow cytometry. Our results were combined with crystal structure data of complexed US2/HLA-A2/β2-microglobulin and alignments of 948 HLA class I database sequences of the endoplasmic reticulum lumenal region inplicated in US2 binding. This study suggests that surface expression of all HLA-A and -G and most HLA-B alleles will be affected by US2. Several HLA-B alleles and all HLA-C and -E alleles are likely to be insensitive to US2-mediated degradation. We also found that the MHC class I endoplasmic reticulum-lumenal domain alone is not sufficient for degradation by US2, as illustrated by the stability of soluble HLA-G1 in the presence of US2. Furthermore, we showed that the membrane-bound HLA-G1 isoform, but also tailless HLA-A2, are targeted for degradation. This indicates that the cytoplasmic tail of the MHC class I H chain is not required for its dislocation to the cytosol by US2.
On style momentum strategies

Barberis and Shleifer (2003) suggest that US investors classify assets into different styles based on, for example, market capitalization or B/M ratios. They find that prices can deviate substantially from fundamental values as a style's popularity changes over time. In this paper, we discuss implications of this prediction and empirically investigate the profitability of style momentum strategies for the UK stock market. Results suggest that a simple trading rule can generate significant positive returns, but for our sample of FTSE 350 stocks those strategies are less profitable and more risky compared to regular momentum strategies.
Gender and Racial Earnings Differentials in Academic Labor Markets

This study estimates earnings differentials across racial and gender groups among college faculty, and decomposes these differentials into the components attributable to differences in individual and institutional characteristics and that which remains unexplained. We find that white females earn approximately 4 percent less than white males; black males earn 7.4 percent more; black females earn one percent more; Hispanic males earn 2.7 percent more; Hispanic females earn 1.7 percent less; and Asian males earn 7.7 percent more than comparable white males. We also find a significant earnings penalty for being a naturalized citizen or noncitizen versus an U.S.-born citizen. Copyright 2000 by Oxford University Press.
The Comparative Effects of Risperidone Long-Acting Injection and Paliperidone Palmitate on Social Functioning in Schizophrenia: A 6-Month, Open-Label, Randomized Controlled Pilot Trial

Purpose: The aim of this study was to compare the effects of risperidone long-acting injection (RLAI) and paliperidone palmitate (PP) on non-acute-phase social functioning in patients with schizophrenia. Patients and Methods: In this 6-month pilot, open-label, randomized controlled study, 30 patients with schizophrenia who had been treated with RLAI were randomly allocated to the RLAI continuation group or switched to the PP group. Patients were evaluated at baseline and 6 months with the Social Functioning Scale (SFS) as the primary outcome variable and University of California San Diego Performance-Based Skills Assessment Brief (UPSA-B), Social Emotional Cognition Task (SECT), Positive and Negative Syndrome Scale (PANSS), and Drug-Induced Extrapyramidal Symptoms Scale (DIEPSS) scores as secondary outcomes. Results: At baseline, the two groups did not significantly differ in demographic or clinical features. The two groups did not differ in total score changes for the UPSA-B, the SECT, the PANSS, and the DIEPSS. However, the total scores and the two subscales of the SFS, i.e. independence-competence and independence-performance, were more improved in the PP group compared to the RLAI group (total scores, p = 0.038; competence, p = 0.001, and performance, p = 0.007, respectively). Conclusion: These results suggest that PP may improve the total social functioning, independent life competence, and performance as compared to the RLAI group. However, these results are preliminary and need independent replication in larger samples before any definitive statement can be made.
Strategic Politicians and U.S. House Elections, 1874–1914

One of the most fundamental changes in post-World War II congressional elections has been the rise of candidate-centered campaigns. This phenomenon has given rise to considerable theoretical and empirical literature demonstrating the strategic behavior of congressional candidates. Yet very few scholars have assessed the effect or existence of strategic candidate behavior for the pre-World War II era. We seek to fill part of this void by exploring the extent to which experienced or quality candidates played a role in influencing the electoral fortunes of incumbent House members in elections spanning the late nineteenth and early twentieth centuries. Our findings suggest that in terms of strategic emergence and electoral performance, congressional candidates exhibited patterns of behavior which are strikingly similar to those seen in modern-day campaigns, suggesting that individual ambition is the best explanation for candidate behavior in both eras.
