Evaluating Programs for the Gifted: Four Questions About the Larger Issues

This paper discusses four major issues concerning the evaluation of programmes for the gifted. 1 The need to evaluate gifted programmes so that planning, development and accountability form a natural sequence of educational objectives. 2 Decisions for change and improvement can only be made in the light of sound evaluation and this evaluation must consider the practical as well as the educational issues. 3 Evaluation should be diagnostic and specific to a particular programme. 4 It must be recognised that the evaluation of gifted programmes requires awareness of the problems associated with assessing ‘higher level’ objectives; the unsuitability of conventionally standardized tests and the practical demand on time, money and trained personnel.
Fdi technology spillovers in China: Implications for developing countries

Since the 1980s, multinational corporations (MNCs) have increasingly invested in production and service facilities in developing countries. In the meantime, developing countries adopted preferential policies to attract foreign direct investment (FDI) in the hope that FDI can bring in advanced technology. However, FDI is a double-edged sword, generating positive as well as negative technology spillovers. Extant studies focus on the simple issue of whether the presence of FDI affects domestic firms, and have limited policy implications for developing countries. This paper is intended to fill this research gap. Differing from extant studies, the paper tries to identify the individual channels through which positive and negative FDI technology spillovers take place in different entry modes, and draws practical implications for developing countries in making policies on MNC entry modes and investment priorities. The paper distinguishes between different forms of FDI presence, including tangible assets and intangible assets, exported products and domestically sold products, new products and traditional products, employment of skilled workers and employment of unskilled workers, and takes them as different channels by which FDI technology spillovers take place. Meanwhile, the paper distinguishes between wholly foreign owned enterprise and joint venture, and takes the two entry modes as different organizational settings in which FDI technology spillovers occur. The paper then examines how FDI technology spillovers take place through each of these channels under each of the entry modes, and tests hypotheses against firm-level data from China. The study finds that positive FDI technology spillovers take place through tangible rather than intangible assets, domestically sold rather than exported products, traditional rather than new products, and employment of unskilled rather than skilled workers in joint ventures. In contrast, negative FDI technology spillovers take place through exported products and employment of skilled workers in wholly foreign owned enterprises. The findings suggest that developing countries should encourage MNCs to enter their markets in the form of joint ventures rather than wholly foreign owned enterprises. Moreover, they should encourage MNCs to invest in tangible assets, production of domestically-consumed products and traditional products, and employment and training of unskilled local workers in joint ventures. Furthermore, they should help domestic firms overcome the adverse effect of market stealing and skill stealing generated by wholly foreign owned enterprises.
Immature development and adult eclosion of Ufens principalis Owen (Hymenoptera: Trichogrammatidae), an egg parasitoid of Homalodisca spp. (Hemiptera: Cicadellidae) in southern California

Abstract The biology of the immature stages and adult eclosion of Ufens principalis Owen, an important parasitoid of Homalodisca eggs in southern California, were studied. The duration of the egg, larval and pupal stages at 26.7°C were 0–1, 7 and 9 days, respectively. Sacciform larvae, which developed gregariously within host eggs, were motile until about five days of age, and then became sessile. Parasitized host eggs changed from whitish and soft when freshly-laid to yellow-orange and hard at five days and older. This change was accompanied by formation of septal walls separating the mature larvae and pupae. The rate of immature development had a strong positive linear relationship (R2=0.853, n=98) with temperatures in the range of 20.0–30.3°C. The theoretical minimum threshold for immature development was 13.5°C, and the required heat units were 241.0 degree-days. Adult eclosion from host eggs occurred mostly (85%) on the first two days of emergence. Although most females emerged during the morning hours (0600–1200 h), males tended to emerge earlier than females with equal emergence during the morning and late night hours (2400–0600 h). The rate of successful adult emergence was high (88%). The ratio of eclosed adults to the number of exit holes was 1.18, indicating that most adults tended to independently cut their exit holes. The number of exit holes had a strong negative relationship (R2=0.711, n=125) with exit hole size, suggesting that larger numbers of developing immatures per host egg result in an overall decrease in adult size.
Resource management for Sustainable Development of Island Economies

What is the role of resource management in sustaining competitiveness for island economies such as the Republic of the Philippines and Hawaii? We review the history of thought on sustainable resource management and sustainable development and then turn to the threats to sustainability from the resource curse and the parallel curse of paradise. We show how the resource curse undermines the pursuit of sustainability and describe innovations in governance that can transform the curse into a blessing.
Satisfaction or Quality Comes First: An Empirical Analysis

ABSTRACT This article assesses and compares two different models that include (a) the relationships of quality dimensions with satisfaction and associated intended future behavior and (b) the relationships of satisfaction with quality dimensions and associated intended future behavior for visitors who attended entertainment events/shows at two venues. A structural analysis of 8,446 responses provided by the Charlotte Regional Visitors Authority in Charlotte, North Carolina, suggests that both models are statistically acceptable and some significant relationships are found among satisfaction, three quality dimensions (the entertainment show offered, the services associated with the venue, and the treatment by staff), and intended future behavior. A brief comparison of the two models is discussed in terms of the structural relationships, the strengths, and the values of goodness-of-fit indices. The findings may contribute to the conceptual development of the existing literature as one of the first few works to study satisfaction, quality, and future behavior intentions in the entertainment and event area. The article ends by providing practical facilitation of related managerial directions in the entertainment industry and suggests directions for future research.
Ownership Identity and Concentration: A Study of Their Joint Impact on Corporate Diversification

This paper examines the impact of ownership on product and international diversification. While ownership concentration has received considerable attention from agency theorists we argue that a more nuanced analysis is necessary. We consider how the identity of owners moderates the impact of ownership concentration on diversification strategies. We develop a framework that explains how the combination of different motivations, resources and capabilities associated with different types of owners results in significantly variable relationships between ownership concentration and both product and international diversification. From a theoretical perspective this suggests a social contextualization and extension of the agency theoretic approach that characterizes the field. Based on a study of 222 European firms between 1994 and 2007 we show that family ownership concentration has a positive impact on product and a negative impact on international diversification while the impact of institutional and state ownership concentration is negative on product diversification and positive on international diversification compared with family ownership. This is the first study to provide a comprehensive framework explaining how ownership concentration and identity interact and affect both international and product diversification.
Financial Volatility and Economic Activity

Does capital markets uncertainty affect the business cycle? We find that financial volatility predicts 30% of post-war economic activity in the United States, and that during the Great Moderation, aggregate stock market volatility explains, alone, up to 55% of real growth. In out-of-sample tests, we find that stock volatility helps predict turning points over and above traditional financial variables such as credit or term spreads, and other leading indicators. Combining stock volatility and the term spread leads to a proxy for (i) aggregate risk, (ii) risk-premiums and (iii) monetary policy, which is found to track, and anticipate, the business cycle. At the heart of our analysis is a notion of volatility based on a slowly changing measure of return variability. This volatility is designed to capture long-run uncertainty in capital markets, and is particularly successful at explaining trends in the economic activity at horizons of six months and one year.
Comparative Analysis of Recent Trends in Private Sector Development in CEE Transition Economies

Abstract We investigate developments in private sector activity as proxied by business ownership (BO) rates in four Central and East European (CEE) transition economies (the Czech Republic, Hungary, Poland and the Slovak Republic) and compare them with similar developments in other OECD countries in the period 1989–2008. Our analysis reveals that BO rates in the four CEE countries have been converging rapidly towards the levels of other OECD countries, and these CEE countries were able to rebuild their private sectors in a relatively short period of transition. We also find sizable differences among the four CEE countries under study in the level and dynamics of change of BO since 1989.
Cancer larynx detection using glottal flow parameters and statistical tools

One of the most interesting application of speech processing is the identification and classification of pathological voice. Such area of research is still a challenging task. In this paper, we are interested in the severe case of the pathological voice; larynx cancer. This work concentrates on developing a feature extraction for detecting and classifying larynx cancer by investigating different glottal flow parameters. Once the glottal flow is extracted, temporal and frequency parameters are calculated. From the large obtained set of parameters, we choose the most pertinent in terms of pathologic/normal discrimination. For this purpose, a deep analysis of statistical tools such as boxplot and probability density permits to select and ordered the most significant parameters. The detection and the classification of the larynx cancer is achieved by artificial neural network (ANN). A rate about 96.9 % of the discrimination accuracy is achieved using the developed technique.
When trade unions succeed: Cases of blocked liberalisation in the common market

Despite the generally accepted weakness of trade unions at the European Union level, an analysis of two high profile cases - the Services Directive and the Port Directive - shows that trade unions are able to mobilise effectively at the European level and, within constellations of actors, crucially impact EU decision making. In contrast to common claims that a lack of access to EU institutions makes such groups powerless, it is argued here that the exclusion of large opposing societal groups from consultations is neither a quick nor a sure fire recipe for dismantling opposition.On the contrary,it politicises the process and may lead to opposing groups mobilising in more contentious ways.
ASSESSING THE IMPACT OF DISTRIBUTIVE POLICIES ON THE BRAZILIAN ECONOMY USING AN SCGE MODEL

This study investigates the impact of macroeconomic policies on the Brazilian economy. We present a two-sector, open-economy, Structuralist Computable General Equilibrium model that distinguishes among three economic classes and assumes no financial sector. The Social Accounting Matrix for Brazil in 2006 serves as a benchmark for our model. We compare the medium-run effects of five experiments: an income transfer towards formal workers, a transfer to informal labour, an investment shock, an exchange rate depreciation, and a policy mix that combines (exchange rate) depreciation with income transfer towards modern (sector) workers. The policy measures reinforce each other in terms of their potential to enhance growth. Our findings underscore the importance of redistributive policies to foster economic expansion.
Dairy cow cleanliness and milk quality on organic and conventional farms in the UK

A subjective cow cleanliness scoring system was validated and used to assess the cleanliness score of dairy cows at different times in the year. A longitudinal study followed a number of farms from summer to winter, and a larger, cross-sectional study assessed a greater number of farms during the housed winter period. The scoring system was demonstrated to be both a repeatable and practical technique to use on-farm and showed that cows become dirtier in the transition from summer grazing to winter housing. Although farming system (organic or conventional) had no effect on cow cleanliness when cows were at grass, when housed in the winter, organic cows were significantly more likely to be cleaner. There was a link between cow cleanliness scores and milk quality, with herds having lower bulk tank somatic cell counts (BTSCC) tending to have a lower (cleaner) median cow cleanliness score; with this relationship strongest for the organic herds. There was no significant link between cleanliness score and Bactoscan (BS) count or clinical mastitis incidence. No major mastitis pathogens were cultured from bulk tank milk samples from the quartile of herds with the cleanest cows in contrast to the quartile of herds with the dirtiest cows, where significant mastitis pathogens were cultured. Based on this study, all farms, especially organic systems, should attempt to keep cows clean as part of subclinical mastitis control.
Handling the Two Conflicting Discourses of Partnerships and Participation in Regional Planning

Abstract This article argues that regional planning is dominated by two conflicting discourses that have different principles of involvement: the discourse of partnerships and the discourse of broad participation. These discourses and principles are not easy to reconcile in practice. On the basis of studies in the literature and a comprehensive case study, this article discusses how these conflicting discourses in regional planning challenge democratic norms, and how this problem is dealt with by the regional political leadership. The article shows that the use of meta-governance strategies and broad arenas of participation might be used in this respect, for example, by constantly having a focus on maintaining democratic anchorage when partnerships are used in regional planning processes.
Clinical and Molecular epidemiologic analyses of norovirus‐associated sporadic gastroenteritis in adults from Beijing, China

Noroviruses (NoVs) are a major cause of nonbacterial acute gastroenteritis. The molecular epidemiology of NoV infections in China has not been well characterized. To study the incidence of NoV infections and the nature of the circulating NoV genotypes, 403 specimens were collected from adult outpatients with acute gastroenteritis in Beijing, China, between October 2007 and September 2008. Samples were examined for NoV by reverse transcriptase‐polymerase chain reaction (RT‐PCR) and sequences corresponding to both the NoV polymerase and capsid regions were characterized. Among the 403 specimens, 48 (11.9%) were positive for NoV and 1/3 NoV‐associated gastroenteritis cases occurred during the colder months (November and December). Based on polymerase region sequences, 6 NoV genotypes (GII‐4, GII‐b, GII‐6, GI‐2, GI‐3, and GI‐4) were identified with GII‐4 2006b being the most predominant genotype (37/48, 77.1%). Eleven distinct genotype sequences in polymerase and capsid regions were identified, indicating a genetic diversity among NoV isolates. This study suggested NoVs were an important pathogen responsible for sporadic acute gastroenteritis in adults in Beijing, China. J. Med. Virol. 83:1078–1085, 2011. © 2011 Wiley‐Liss, Inc.
Mutational Analysis of the Escherichia coli PhoQ Sensor Kinase: Differences with the Salmonella enterica Serovar Typhimurium PhoQ Protein and in the Mechanism of Mg2+ and Ca2+ Sensing

ABSTRACT The PhoP-PhoQ two-component system plays a role in Mg2+ homeostasis and/or the virulence properties of a number of bacterial species. A Salmonella enterica serovar Typhimurium PhoQ sensor kinase mutant, in which the threonine at residue 48 in the periplasmic sensor domain is changed to an isoleucine, was shown previously to result in elevated expression of PhoP-activated genes and to affect mouse virulence, epithelial cell invasion, and sensitivity to macrophage killing. We characterized a complete set of proteins having amino acid substitutions at position 48 in the closely related Escherichia coli PhoQ protein. Numerous mutant proteins having amino acid substitutions with side chains of various sizes and characters displayed signaling phenotypes similar to that of the wild-type protein, indicating that interactions mediated by the wild-type threonine side chain are not required for normal protein function. Changes to amino acids with aromatic side chains had little impact on signaling in response to extracellular Mg2+ but resulted in reduced sensitivity to extracellular Ca2+, suggesting that the mechanisms of signal transduction in response to these two divalent cations are different. Surprisingly, the Ile48 protein displayed a defective phenotype rather than the hyperactive phenotype seen with the S. enterica serovar Typhimurium protein. We also describe a mutant PhoQ protein lacking the extracellular sensor domain with a defect in the ability to activate PhoP. The defect does not appear to be due to reduced autokinase activity but rather appears to be due to an effect on the stability of the aspartyl-phosphate bond of phospho-PhoP.
SOME PROPERTIES OF WEAK DOMINATION IN AN EXCHANGE MARKET WITH INDIVISIBLE GOODS*

We investigate general properties of weak domination in the Shapley-Scarf exchange model with indivisible goods. We prove that every weakly dominated allocation is weakly dominated by some competitive allocation. Furthermore, if an allocation does not weakly dominate some other allocation, it is a weakly dominated allocation or the two allocations are indifferent. By using these results, we show that every non-competitive allocation is weakly dominated by some competitive allocation. The nonempty strong core proves to be a von Neumann-Morgenstern solution. We give also a necessary and sufficient condition for the equivalence of the strong core and the competitive allocations.
Testing the Educational Screening Hypothesis

Human capital theorists have traditionally argued that individuals invest in education until the marginal gain in productivity is equal to the marginal opportunity cost. However, the observed correlations among income, education, and ability measures are also consistent with education being used to screen for exogenous ability differences. This paper tests for such an informational role, arguing that screening will be much more important in some occupations than in others. Subsamples of "screened" and "unscreened" occupations are isolated and compared. It is concluded that observed differences, not readily explained by the traditional model, are consistent with the educational screening hypothesis.
Tissue Factor and Tissue Factor Pathway Inhibitors TFPI and TFPI2 in Human Secretory Endometrium—Possible Link to Female Infertility

The aim of this study was to investigate tissue factor (TF) and its inhibitors TFPI and TFPI2 in secretory endometrium of fertile women and in women with unexplained infertility in relation to endometrial receptivity. In addition, common variation in the regulatory area of TF and TFPI genes was studied. Immunostaining of TF and TFPI, together with the appearance of pinopodes, revealed similar expression pattern in fertile endometrium throughout the secretory phase, being highest at the time of implantation. When compared protein expression levels at the time of implantation, infertile women demonstrated significantly higher TFPI expression in luminal epithelium. Furthermore, polymorphism TF -603 A/G was associated with the endometrial protein level in infertile women, being highest in women with GG genotype, and variation TFPI -287 T/C was associated with unexplained infertility, where infertile women presented more frequently T allele than fertile women. Contrary to TF and TFPI, TFPI2 showed different mRNA and protein expression patterns in fertile endometrium, and no differences between fertile and infertile women were detected. We conclude that the TF pathway is involved in normal endometrial maturation, where TF and TFPI seem to have important roles at the time of embryo implantation. Higher TFPI expression level during the time of embryo implantation and TFPI -287 T allele could be risk factors for unexplained infertility. No distinct involvement of TFPI2 in the regulation of endometrial receptivity and unexplained infertility was found.
Numbers, nuances and moving targets: converging the use of corruption indicators or descriptors in assessing state development

This article is concerned with three issues: the convergence of donors over a shared development agenda, on why dealing with corruption is seen as a key aspect of the agenda, and the means to assess corruption within the context of monitoring development progress. The article reviews the genesis of the agenda, and why corruption is often used as an indicator or measure of progress. It distinguishes between two general approaches—quantitative indicators and qualitative descriptors—for assessing types and levels of corruption before considering methodological and interpretative issues relating to each approach. It suggests that, while each has a role, cognizance should be made of the awareness of the limitations of either for policy- or reform-related issues, particularly in terms of the exercise of political power or the nature and direction of development. The necessary convergence of the use of the two approaches has not been fully achieved to date and, until such time as a convergence is achieved, an over-reliance on one or other approach may not provide an effective basis for reform and aid initiatives, nor for assessing the progress and impact of both in delivering the development agenda.
