Accounting for the Uncertainty in the Evaluation of Percentile Ranks

In a recent paper entitled "Inconsistencies of Recently Proposed Citation Impact Indicators and how to Avoid Them," Schreiber (2012, at arXiv:1202.3861) proposed (i) a method to assess tied ranks consistently and (ii) fractional attribution to percentile ranks in the case of relatively small samples (e.g., for n < 100). Schreiber's solution to the problem of how to handle tied ranks is convincing, in my opinion (cf. Pudovkin & Garfield, 2009). The fractional attribution, however, is computationally intensive and cannot be done manually for even moderately large batches of documents. Schreiber attributed scores fractionally to the six percentile rank classes used in the Science and Engineering Indicators of the U.S. National Science Board, and thus missed, in my opinion, the point that fractional attribution at the level of hundred percentiles-or equivalently quantiles as the continuous random variable-is only a linear, and therefore much less complex problem. Given the quantile-values, the non-linear attribution to the six classes or any other evaluation scheme is then a question of aggregation. A new routine based on these principles (including Schreiber's solution for tied ranks) is made available as software for the assessment of documents retrieved from the Web of Science (at this http URL).
The Bridge to Retirement

Older workers’ choice of bridging employment (self-employment and wage-and-salary employment) was surveyed. Health status was found to be the only shared factor positively influencing both work commitment and the intention to work. Other than the aforementioned, those choosing entrepreneurship or wage-and-salary employment exhibited different demographics and answered dissimilar psycho-social needs. In terms of demographics, self-employed older workers included more unmarried, female respondents, whereas significantly more married males occupied wage-and-salary positions. In terms of psycho-social factors, the commitment and intention to work in the self-employed were significantly associated with responding to needs for personal fulfilment and independence. In contrast, those choosing wage-and-salary employment were significantly responding to needs for generativity, continued contribution, work connection and new experiences.
Rent-Seeking Bureaucracies and Oversight in a Simple Growth Model

Following recent cross-country empirical work, research on public policy and growth has come to examine the impact of inefficient or corrupt bureaucracies. Most of this work has emphasized the interactions of bureaucracies with private markets. By contrast, this paper focuses on the relationship between rent-seeking bureaucracies and their political authority. We show that when oversight is relatively costly, as in many developing economies, the political authority exercises little monitoring of its agencies which reduces the effectiveness of productive government spending. Moreover, when the technology used to provide public services is poor, bureaus better succeed in requesting overly large budgets before triggering any monitoring. Both of these characteristics contribute to reducing the growth rate of already poor economies.
Chondrocytes from Different Zones Exhibit Characteristic Differences in High Density Culture

Superficial and middle/deep zone chondrocytes were isolated from goat femoral cartilage by a zonal abrasion method. The cells were expanded 100-fold through two passages, then seeded into agarose wells to form high-density constructs through a self-assembling process. After 4 weeks in culture, the superficial zone constructs contracted into a dense cell mass, while middle/deep zone chondrocytes formed constructs with four distinct regions. Middle/deep zone chondrocytes produced 250% more glycosaminoglycans per dry weight and more collagen per dry weight than superficial zone chondrocytes. The superficial and middle/deep zone chondrocytes were found to retain characteristic differences even after 100-fold expansion, as evidenced by construct morphology and extracellular matrix content. This study uniquely demonstrated the ability of expanded superficial and middle/deep zone chondrocytes to form constructs of distinct characteristics without a scaffold. The goal of tissue engineering different zones of cartilage is to eventually replicate the specific function of each zone.
THE CAPITAL BUDGETING BEHAVIOUR AND CORPORATE CHARACTERISTICS OF CAPITAL‐CONSTRAINED FIRMS

This paper addresses (1) the nature and pervasiveness of organisational constraints, frnancial and otherwise, on investment, and (2) the corporate characteristics and capital budgeting behaviour of capital-constrained firms for a sample of 126 UK companies. The results indicate that corporate size, risk and profitability are important corporate characteristics in this regard, and that financially-constrained firms tend to adopt naive capital budgeting methods in resolving the capital rationing problem.
A location‐inventory model with lateral transshipments

We study an infinite horizon periodic stochastic inventory system consisting of retail outlets and customers located on a homogenous line segment. In each period, the total demand, generated by the customers on the line, is normally distributed. To better match supply and demand, we incorporate lateral transshipments. We propose a compact model in which the strategic decisions—the number and locations of retail outlets—are determined simultaneously with the operational decisions—the inventory replenishment and transshipment quantities. We find the optimal balance between the risk‐pooling considerations, which drive down the optimal number of retail outlets, and lateral transshipments, which drive up the optimal number of retail outlets. We also explore the sensitivity of the optimal number of retail outlets to various problem parameters. This article presents a novel way of integrating lateral transshipments in the context of an inventory‐location model. © 2011 Wiley Periodicals, Inc. Naval Research Logistics, 2011
Neuropsychological Prediction of Decline to Dementia in Nondemented Elderly

This study examined whether baseline neuropsychological performance in elderly assessed at a research clinic could accurately predict subsequent decline to dementia. Logistic regression analyses were applied to (1) 213 nondemented elderly with a Global Deterioration Scale (GDS) score of 1, 2, or 3, of whom 74 (35%) subsequently declined to any diagnosis of dementia, and (2) a diagnostically more restricted subset of this sample (N = 179), of whom 56 (31%) declined to a diagnosis of probable Alzheimer's disease (AD). The mean follow-up intervals were 3.8 and 3.7 years, respectively. A small set of baseline neuropsychological measures (especially a Paragraph Delayed Recall Test) significantly differentiated decliners from nondecliners to dementia or AD, after accounting for the contribution of age, sex, education, follow-up interval, and the rating of global clinical status. When examined in combination with the other factors or alone, the cognitive tests produced reasonably high specificities (91%-97%) and sensitivities (73%-89%). Using the obtained regression model, a similar level of classification accuracy was replicated on an independent sample of 119 nondemented elderly. A subanalysis of the high-risk GDS 3 subgroup indicated that cut scores from the paragraph test distinguished nondecliners from decliners (overall accuracies 87%-91%), implying that this assessment may accurately predict future cognitive status in elderly with mild cognitive impairment.

Explaining IPOs Underpricing in the Tunisian Market

This article tests four hypotheses (signalling, market tendency, market characteristics and the ex ante uncertainty and information asymmetry) to explain the initial public offerings (IPOs) underpricing in the Tunisian market. Most of the empirical studies focus mainly on developed markets and only a few studies analyse the climates of IPOs in emerging markets. The Tunisian business environment is motivating because of the institutional reforms that have been successfully implemented since 1994. The study analyses all the Tunisian IPOs from March 1992 to April 2008 in order to explain underpricing in IPOs. The findings show that IPOs underpricing is mainly explained by the signalling and the market characteristics hypotheses. The phenomenon of underpricing in IPOs is important for portfolio managers who are expected to make optimal (value-maximising) financing choices. Also, results of this study provide insight into the business environment in the case of the Tunisian market.
Explaining Wage Inequality in Telecommunications Services: Customer Segmentation, Human Resource Practices, and Union Decline

This study examines factors related to within-occupation wage inequality among service and sales workers in the telecommunications industry. The author draws on a 1998 survey of a nationally representative sample of 354 service and sales centers in the industry to examine the importance of management practices and union institutions in shaping wage variation. The results strongly indicate that business strategies of customer segmentation and human resource practices explain variation in wages over and above that explained by the human capital of the work force. In addition, despite extensive deregulation and de-unionization of the industry, the union wage premium is 22%.

Posttraumatic Embitterment Disorder

Background: Adjustment and reactive disorders are a heterogeneous group of mental disorders. Diagnostic criteria are vague and scientific research is limited despite the fact that these disorders play a major role in clinical practice. Methods: The ‘posttraumatic embitterment disorder’ (PTED) is introduced as a new concept for a subgroup of adjustment disorders. A case vignette and diagnostic criteria are presented. Results: Core criteria of PTED are: (1) a single exceptional negative life event precipitates the onset of the illness; (2) the present negative state developped in the direct context of this event; (3) the emotional response is embitterment and feelings of injustice; (4) repeated intrusive memories of the event; (5) emotional modulation is unimpaired, patients can even smile when engaged in thoughts of revenge, and (6) no obvious other mental disorder that can explain the reaction. Additional symptoms are feelings of helplessness, self-blame, rejection of help, suicidal ideation, dysphoria, aggression, down-heartedness, seemingly melancholic depression, unspecific somatic complaints, loss of appetite, sleep disturbances, pain, phobic symptoms in respect to the place or to persons related to the event, reduced drive. Duration is longer than 3 months. Performance in daily activities and roles is impaired. Conclusions: PTED is a frequent disorder. The diagnosis of PTED can lead to specific therapeutic interventions. PTED can be discriminated from PTSD, depression, anxiety disorders, and other adjustment disorders.
Local Input and Productivity Growth in U.S. Manufacturing: 1972-2002

This research analyzes manufacturing growth and decline across metropolitan and nonmetropolitan regions during the 1972-2002 period. We decompose real value added growth across local labor market areas in the lower 48 U.S. states into contributions from labor, capital, and total factor productivity. We then estimate a model describing the long-run growth of labor, capital, and productivity and find that increased productivity increases the growth of labor and capital, as well as a positive correlation between labor and capital stock growth. We also find evidence that human capital investment and agglomeration economies encourage productivity growth, while unionization discourages it.
Cloning of a Gene Cluster Encoding Enzymes Responsible for the Mevalonate Pathway from a Terpenoid-antibiotic-producing Streptomyces Strain

A gene cluster encoding enzymes responsible for the mevalonate pathway was isolated from Streptomyces griseolosporeus strain MF730-N6, a terpenoid-antibiotic terpentecin producer, by searching a flanking region of th 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase gene, which had been previously isolated by complementation. By DNA sequencing of an 8.9-kb BamHI fragment, 7 genes encoding geranylgeranyl diphosphate synthase (GGDPS), mevalonate kinase (MK), mevalonate diphosphate decarboxylase (MDPD), phosphomevalonate kinase (PMK), isopentenyl diphosphate (IPP) isomerase, HMG-CoA reductase, and HMG-CoA synthase were suggested to exist in that order. Heterologous expression of these genes in E. coli and Streptomyces lividans, both of which have only the nonmevalonate pathways, suggested that the genes for the mevalonate pathway were included in the cloned DNA fragment. The GGDPS, MK, MDPD, PMK, IPP isomerase, and HMG-CoA synthase were expressed in E. coli. Among them, the recombinant GGDPS, MK, and IPP isomerase were confirmed to have the expected activities. This is the first report, to the best of our knowledge, about eubacterial MK with direct evidence.
High Frequency of Clonal Immunoglobulin Receptor Gene Rearrangements in Sporadic Histiocytic/Dendritic Cell Sarcomas

The diagnosis of histiocytic/dendritic cell (H/DC) sarcomas is currently based on morphology and the presence of immunophenotypic features of H/DC differentiation. The issue whether clonal immunoglobulin receptor gene rearrangements are present in H/DC sarcomas has been debated over decades until the recent data by Feldman et al, which provided compelling evidence that patients with follicular lymphoma and concurrent/synchronous H/DC sarcoma share identical genotypic features, suggested the possibility of transdifferentiation or dedifferentiation of 2 otherwise morphologically and immunophenotypically distinctive neoplasms. Here we investigated the molecular characteristics of 23 patients with sporadic H/DC sarcoma. Nine of the 23 cases (39%) showed clonal IGH (±IGK) gene rearrangements, whereas 2 (9%) cases showed only clonal IGK gene rearrangements, which were further validated and confirmed by direct DNA sequencing. One histiocytic sarcoma showed t(14;18) by quantitative-polymerase chain reaction, which was confirmed by fluorescence in situ hybridization analysis showing IGH/BCL2 fusions in neoplastic histiocytes. Notably, all IGH/IGK-positive H/DC sarcomas were negative for B-cell–associated transcription factors PAX5 and BOB.1, whereas 4 of 7 IGH/IGK-positive histiocytic sarcoma cases were positive for Oct2. In addition, no evidence of Epstein-Barr virus infection was detected in 8 of 11 IGH/IGK-positive H/DC sarcoma cases by in situ hybridization, suggesting that Epstein-Barr virus infection may not play an important role in the pathogenesis of these tumors. This study provides evidence that clonal immunoglobulin receptor gene rearrangements may be detected at a high frequency in sporadic H/DC sarcomas. The findings suggest that a large subset of H/DC sarcomas have inherited B-cell genotypes, thus providing new insights for the pathogenesis of these rare but aggressive neoplasms.
Expanding Enrollments and Contracting State Budgets

The Great Recession heightened a growing conflict in the United States between expanding enrollments in postsecondary education and contracting public budget support. Weak labor market conditions during the Great Recession encouraged college enrollments, with much of the increase in enrollment occurring outside the most selective institutions. While federal aid policies, including the Pell grant, became more generous, dramatic reductions in state budget allocations made it difficult for colleges and universities to maintain programming and accommodate student demand. As a result, the Great Recession has accelerated the cost-shifting from public subsidies to individual payments in higher education.
Contribution of Axial Arm Rotation to Humeral Head Translation

The contribution of axial arm rotation to translation of the humeral head with the arm in the hanging position was examined using nine fresh-frozen cadaveric shoulders. Three standard clinical tests were simulated: anterior and posterior translation and sulcus tests. In both the anterior translation and sulcus tests, anterior and infe rior displacements were significantly restricted in inter nal rotation but not in neutral and external rotation. In the posterior translation test, no significant differences in displacement could be observed in internal, neutral, or external rotation. Since anterior and inferior translations of the humeral head were significantly affected by the rotation of the arm, we recommend that the anterior translation and sulcus tests be performed in various rotations.
Building Effective Employment Programs for Unemployed Youth in the Middle East and North Africa

This study surveys active labor market programs (ALMPs) in selected countries of the Middle East and North Africa (MENA) region, identifies key challenges to their effective and efficient delivery, and proposes a policy framework for reforming public service provision. This study draws on data collected through surveys administered to public social, employment, and education agencies in selected MENA countries to identify key constraints and options for reforming publicly provided employment programs. Recent political transitions arising from the Arab Spring have contributed to the deterioration of labor market outcomes in the MENA region. In this context, ALMPs could become an important policy lever to address some of the challenges facing labor markets. These include: joblessness, skills mismatches, lack of labor market mobility, large and expanding informal sector, and lack of formal employment networks. The study also provides specific details on the beneficiaries, targeting, and expenditures of ALMPs during this same period.
Prothrombin Synthesis in the Adult and Fetal Liver

Summary Plasma levels of blood coagulation zymogens are lower in the newborn than in the adult, with the lowest levels being in preterm infants. It is not known if the lower coagulation factor levels reflect differences in synthesis, secretion or catabolism. Using a rabbit model we have compared prothrombin synthesis in the fetus and adult. In previous studies we attempted to compare transcription in the adult and fetal liver by extraction of mRNA, immobilization on a membrane and hybridization with a labeled cDNA for rabbit prothrombin. Comparison was impaired by the markedly dissimilar composition of fetal and adult rabbit liver; fetal liver is approximately fifty percent hematopoietic tissue even at term (1). In the present study, to obtain a more meaningful comparison we have employed in situ hybridization to compare directly prothrombin expression in adult and fetal liver. We report here that fetal liver contains more prothrombin mRNA than does adult liver. We have further compared prothrombin levels in protein extracts of adult and fetal liver and found that per microgram of extract, fetal liver contains as much prothrombin as does the adult. We conclude that the lower plasma prothrombin levels in the fetus do not reflect a lower rate of synthesis.
Competition and Innovation: Evidence from US Patent and Productivity Data

Is there any evidence that innovation and technological progress are constrained by competition and fostered by monopoly power? Our results, based on a constructed dataset of U.S. manufacturing industries observed over more than two decades, suggest that this is not the case. On the contrary, using both patent statistics and productivity growth as alternative measures of innovation and technological change, we observe faster technological advances in more competitive markets. These results are robust to changes in the econometric techniques used to model nonlinearity in the competition-innovation relationship and to alternative methods of computing market power.
The Strange Birth of Liberal Denmark: Danish Trade Protection and the Growth of the Dairy Industry Since the Mid‐Nineteenth Century

The usual story of the ‘first era of globalization’ at the end of the nineteenth century sees Denmark as something of an outlier: a country which, like the UK, resisted the globalization backlash in the wake of the inflow of cheap grain from the New World, but where agriculture, rather than going into decline, in fact flourished. Key to the success of Danish agriculture was an early diversification towards dairy production. This article challenges this simple story which sees Denmark as something of a liberal paragon. Denmark's success owed much to a prudent use of trade policy which favoured dairy production. Moreover, this favouritism continued even after a more general movement to free trade in the 1860s. Using micro‐level data from individual dairies, we quantify the implied subsidy to dairy production from the tariffs, and demonstrate that in many cases this ensured the profitability of individual dairies.
Specific reduction of alcohol's motivational properties by the positive allosteric modulator of the GABAB receptor, GS39783--comparison with the effect of the GABAB receptor direct agonist, baclofen.

BACKGROUND Activation of the GABA(B) receptor--either by means of direct agonists (like baclofen) or positive allosteric modulators (like GS39783)--has been observed to suppress alcohol drinking and reinforcement in rats and mice. The present study was conducted to assess and compare the effect of baclofen and GS39783 on the motivational properties of alcohol. METHODS Selectively bred Sardinian alcohol-preferring (sP) rats were initially trained to respond on a lever (on an fixed ratio 4 schedule of reinforcement) to orally self-administer alcohol (15%, v/v) or sucrose (3%, w/v) in daily 30-minute sessions. Once lever-responding reached stable levels, rats were exposed to sessions with a progressive ratio schedule of reinforcement. The effect of nonsedative doses of baclofen (0, 1, and 3 mg/kg, i.p.) and GS39783 (0, 25, 50, and 100 mg/kg, i.g.) on breakpoint for alcohol and sucrose (defined as the lowest response requirement not achieved by each rat and used as index of the motivational strength of alcohol and sucrose) was determined. RESULTS Baclofen administration resulted in a dose-dependent decrease in breakpoint for alcohol; this effect was not specific, as baclofen also reduced--to a comparable extent--breakpoint for sucrose. Conversely, GS39783 administration resulted in a dose-dependent and completely specific reduction in breakpoint for alcohol. CONCLUSIONS The present results (i) confirm previous data on baclofen's capacity to suppress, although nonspecifically, alcohol's motivational properties, and (ii) extend to alcohol's motivational properties the capacity of GS39783 to inhibit alcohol drinking and reinforcement in rats.
