Inflation, Uncertainty, and Growth in Colombia

It has been argued that higher levels of inflation lead to greater uncertainty about future inflation and to greater dispersion of relative prices. In either case, inflation could reduce the efficiency of market prices in coordinating economic activities. This paper shows that the rise of inflation in Colombia, from low levels in the 1950s to average rates of 18-22 percent since the 1970s, has been accompanied by increased uncertainty and relative price dispersion; and that inflation has had a negative and persistent effect on real GDP growth.
Urban school reform : lessons from San Diego

An indispensable book for administrators, policymakers, scholars, and practitioners, "Urban School Reform" presents a revealing portrait of reform efforts while identifying the full range of issues that education reformers will need to address in districts across the country in the years ahead. Today's urban school reformers face a bewildering array of challenges. Urgent problems pertaining to governance, management, labor relations, classroom instruction, and numerous other areas face those who wish to reform and improve urban schools. Having undergone one of the nation's most comprehensive school reform efforts in recent years, San Diego has been a site of nationwide interest--one that is uncommonly well suited to learning about the challenges facing all reformers. This timely book addresses the full range of critical issues pertaining to urban school reform by looking closely at the recent reform efforts in San Diego. In essays by an impressive gathering of scholars and practitioners from across the country, the book considers crucial dimensions of reform efforts in the San Diego schools, including performance, governance, the external environment, central leadership and management, district infrastructure, support services, and school-level instructional efforts. The result is a full-scale assessment of San Diego's reform efforts--a record of unmistakable relevance and value to other urban reform movements throughout the United States.
Investigating the relationships between CEO duality, shareholding and entrepreneurial performance: the mediating effect of R&D intensity

This study aims to explore the mediating effect of R&D intensity (RDI) on the relationships between chief executive officer (CEO) duality, shareholding and firm performance. One hundred twenty-seven companies in the semiconductor industry are included in this study. Statistical approaches on three years of data (2006? 2008) are used to examine the theoretical model. It is found that CEO duality and shareholding have positive and significant effects on RDI. On the contrary, CEO duality and shareholding have significant and yet negative effects on firm performance. In addition, RDI mediates the relationships between CEO duality, shareholding and firm performance. It is argued that the effect of RDI on firm performance is not easily predicted in areas of overspill or time lag, due to market competitiveness or time constraint. Suggestions and recommendations for future research are discussed.
Sonoelastography in the Evaluation of Plantar Fasciitis Treatment: 3-Month Follow-Up After Collagen Injection

Objective The aim of this study was to investigate whether ultrasound elastography can demonstrate the outcome of the treatment in comparison with gray-scale imaging. Methods Sixteen patients (mean age, 46.9 years) with plantar fasciitis were prospectively enrolled after unsuccessful conservative treatment. Individuals graded their heel pain on a 100-mm visual analogue scale (VAS) and underwent gray-scale ultrasonography and sonoelastography. Collagen was injected in the heels. Fascial thickness and hypoechogenicity, perifascial edema, and plantar fascial elasticity were evaluated. Follow-up sonoelastography and VAS grading were done 3 months after the injection. Statistical analyses were performed by the paired t test and the Fisher exact test. A P < 0.05 was considered statistically significant. Results Mean plantar fascial thickness showed insignificant decrease on follow-up (from 4.30 [1.37] to 4.23 [1.15] mm, P = 0.662). Fascial hypoechogenicity and perifascial edema did not change significantly after treatment. The mean strain ratio of the plantar fascia was significantly increased (from 0.71 [0.24] to 1.66 [0.72], P = 0.001). Softening of the plantar fascia decreased significantly after injection (from 12 to 3 ft, P = 0.004). Twelve (75%) of 16 patients showed significant VAS improvement at the follow-up. Conclusions Sonoelastography revealed a hardening of the plantar fascia after collagen injection treatment and could aid in monitoring the improvement of the symptoms of plantar fasciitis, in cases where gray-scale imaging is inconclusive.
WTP–WTA disparity among competitive and non-competitive subjects – an experimental study

Recent studies have questioned the existence and interpretation of a possible gap between Willingness-To-Pay (WTP) and Willingness-To-Accept (WTA). The study analyses the bidding patterns in buying and selling lottery tickets that represent financial assets using second price auction, and then tests for the existence of the WTP and WTA gap. It is shown that for lotteries, this gap is not significant for the group of all subjects, but that it may exist for a sub-group of subjects. Subjects were classified according to their degree of competitiveness and a negative gap was found for non-competitive subjects and a positive gap for competitive subjects. These gaps offset each other when the group of all the subjects was used.
Tripartite Adjudication - An Endangered Species

This article focuses on the role of lay members in tripartite employment tribunals, arguing that tribunals' legitimacy has been undermined by restrictions on the use of members' workplace experience, by the growth of the law, by changes to the method of lay member appointment and because judges now decide certain cases alone.
Daily consumption of red grape cell powder in a dietary dose improves cardiovascular parameters: a double blind, placebo-controlled, randomized study

Abstract Consumption of polyphenol-rich food and food ingredient such as grape and grape products improved various cardiovascular parameters. In this study, we investigate the effect of dietary daily consumption of red grape cell powder (RGC) on blood pressure (BP) and flow-mediated dilatation (FMD) as well as on oxidative stress in 50 subjects with prehypertension and mild hypertension. The subjects were randomized into groups that consumed 200, 400 mg RGC or placebo daily for 12 weeks. RGC consumption was associated with an improvement of FMD (p = 0.013). There was a significant decrease in lipid peroxidation (p = 0.013) after 12 weeks in a combined RGC-treated group. The diastolic BP decreased significantly in the 200 mg RGC group compared to the placebo group (p = 0.032). Our results indicate that a daily supplementation, of red grape cell powder, for 12 weeks affects endothelial function, diastolic BP and oxidative stress without any adverse effects.
ENVIRONMENTAL CHANGE AND THE CONTRIBUTION OF BIODIVERSITY TO ECOSYSTEM ADAPTATION

Abstract This paper develops a measure of the contribution of biodiversity in enhancing ecosystem performance that is subject to environmental fluctuation. The analysis draws from an ecological model that relates high phenotypic variance with lower short‐term productivity (due to the presence of suboptimal species) and higher long‐term productivity (due to better ability to respond to environmental fluctuations). This feature, which is a notable extension to existing economic‐ecological models of biodiversity, enables assessment of the interactions between diversity and a range of environmental fluctuations to highlight that biodiversity could be rendered economically disadvantageous when environmental fluctuation is insufficient. The resulting economic‐ecological model generates discounted present value of harvests for an ecosystem with diverse set of species. This value is compared with the harvest value of a similar economic‐ecological model with no diversity and that of an ecosystem where the dynamics of phenotypes in response to environmental fluctuations is disregarded. The results show that diversity positively contributes to the performance of ecosystems subject to sufficiently large environmental fluctuation. In addition, neglecting an ecosystem's increasing ability to adapt to match environmental conditions is also shown to be more costly than having no diversity in an otherwise identical ecosystem.
Remembering the past: two facets of episodic memory explored with positron emission tomography.

OBJECTIVE This study used positron emission tomography to examine two kinds of personal memory that are used in psychiatric evaluation: focused episodic memory (recall of past experience, employed in "taking a history") and random episodic memory (uncensored thinking about experience, examined during analytic therapy using free association). For comparison, a third memory task was used to tap impersonal memory that represents general information about the world ("semantic memory"). METHOD Thirteen subjects were studied using the [15O]H2O method to obtain quantitative measurements of cerebral blood flow. The three conditions were subtracted and their relative relationships examined. RESULTS The random episodic condition produced activations in widely distributed association cortex (right and left frontal, parietal, angular/supramarginal, and posterior inferior temporal regions). Focused episodic memory engaged a network that included the medial inferior frontal regions, precuneus/retrosplenial cingulate, anterior cingulate, thalamus, and cerebellum. The use of medial frontal regions and the precuneus/retrosplenial cingulate was common to both focused and random episodic memory. The major difference between semantic and episodic memory was activation of Broca's area and the left frontal operculum by semantic memory. CONCLUSIONS These results indicate that free-ranging mental activity (random episodic memory) produces large activations in association cortex and may reflect both active retrieval of past experiences and planning of future experiences. Focused episodic memory shares some components of this circuit (inferior frontal and precuneus), which may reflect the time-linked components of both aspects of episodic memory, and which permit human beings to experience personal identity, consciousness, and self-awareness.
Income inequality and mortality: importance to health of individual income, psychosocial environment, or material conditions

Studies on the health effects of income inequality have generated great interest. The evidence on this association between countries is mixed,1–4 but income inequality and health have been linked within the United States,5–11 Britain,12 and Brazil.13 Questions remain over how to interpret these findings and the mechanisms involved. We discuss three interpretations of the association between income inequality and health: the individual income interpretation, the psychosocial environment interpretation, and the neo-material interpretation. #### Summary points Income inequality has generally been associated with differences in health A psychosocial interpretation of health inequalities, in terms of perceptions of relative disadvantage and the psychological consequences of inequality, raises several conceptual and empirical problems Income inequality is accompanied by many differences in conditions of life at the individual and population levels, which may adversely influence health Interpretation of links between income inequality and health must begin with the structural causes of inequalities, and not just focus on perceptions of that inequality Reducing health inequalities and improving public health in the 21st century requires strategic investment in neo-material conditions via more equitable distribution of public and private resources We reviewed the literature through traditional and electronic means and supplemented this with correlational analyses of gross domestic product and life expectancy and of income inequality and mortality trends based on data from the World Bank,14 the World Health Organization,15 and two British sources.16 17 According to the individual income interpretation, aggregate level associations between income inequality and health reflect only the individual level association between income and health. The curvilinear relation between income and health at the individual level 18 19 is a sufficient condition to produce health differences between populations with the same average income but different distributions of income.3 20 This interpretation assumes that determinants …
Opposing actions of TGFβ1 and FGF2 on growth, differentiation and extracellular matrix accumulation in prostatic stromal cells

TGFβ1 and FGF2 are autocrine growth factors in prostatic stroma and are elevated in benign prostatic hyperplasia (BPH), a disease characterized by enlargement of the stromal compartment of the prostate. TGFβ1 has a biphasic effect on proliferation of prostatic stromal cells, inducing proliferation at low doses ( < 1 ng/ml), but inhibiting growth above 1 ng/ml. This study investigated the role of TGFβ1 and FGF2 on growth factor bioavailability and extracellular matrix (ECM) accumulation synthesis in cultured prostatic stromal cells. Real-Time-PCR showed that TGFβ1 expression is auto-inductive, whereas FGF2 is auto-repressive. FGF2 also induced TGFβ1 secretion in the absence of increased TGFβ1 mRNA expression. TGFβ1 and FGF2 have opposing actions on Type 1 collagen expression, a finding confirmed by Western blotting. The bioavailability of TGFβ1 regulated by FGF2 may represent part of a negative feedback mechanism controlling stromal growth, differentiation and ECM. Dysregulation of this pathway in favour of TGFβ1 bioactivity may exacerbate BPH.
Can area-based regeneration programmes ever work? Evidence from England's New Deal for Communities Programme

The New Deal for Communities (NDC) Programme is one of the most intensive area-based initiatives (ABIs) ever launched in England. Between 1998 and 2011, 39 Partnerships were charged with improving conditions in relation to six outcomes within deprived neighbourhoods, each accommodating around 9800 people. The evaluation of the Programme points to only modest net change for NDC areas and their residents, much of which reflects improving attitudes towards the area, rather than for the people-related outcomes of health, education and worklessness. The Programme's architecture was based on four key principles each of which impacted on change. Community engagement reaped fewer benefits, and proved more problematic, than had been anticipated; working with other delivery agencies was complex, providing less in the way the way of direct financial support than was true for other English ABIs; central government impacted on change through an initial over-emphasis on spending annual financial allocations combined with a later marginalisation of ABIs; and outcome change at the neighbourhood level is anyway largely beyond the control of local regeneration schemes. Nevertheless, there are reasons why area-based regeneration schemes might be pursued, including evidence that individuals benefit from local interventions, even if such effects are difficult to measure.
The phylogeny of marine and freshwater caulobacters reflects their habitat

Caulobacter is a distinctive genus of prosthecate bacteria. Because caulobacters adhere to surfaces and are found in diverse locales, their role in oligotrophic environments and bacterial biofilm communities is of interest. The phylogenetic relationships of a group of marine and freshwater caulobacters were examined in part to address whether the taxonomic grouping of these bacteria (based primarily on morphological characters) was consistent with 16S rRNA sequence divergence. The caulobacters examined (9 marine and 11 freshwater species or strains) were affiliated with the alpha proteobacteria. They made up a diverse yet, with the possible exception of a strain of Caulobacter subvibrioides, coherent assemblage. The diversity was most apparent in a comparison of freshwater and marine isolates; an early divergence within the main caulobacter lineage generally corresponded to strains isolated from freshwater and marine habitats. The marine caulobacter assemblage was not exclusive; it also embraced strains of marine hyphomonads and Rhodobacter capsulatus. We hypothesize that these genera are derived from more ancestral caulobacters. Overall, the data are consistent with the interpretation that all of the caulobacters examined, with the possible exception of C. subvibrioides, are ancestrally related, albeit anciently, and that most often division by terrestrial and marine habitats corresponds to an early evolutionary divergence within the genus.
Efficacy and safety of secukinumab, a fully human anti-interleukin-17A monoclonal antibody, in patients with moderate-to-severe psoriatic arthritis: a 24-week, randomised, double-blind, placebo-controlled, phase II proof-of-concept trial

Objective To evaluate the efficacy and safety of secukinumab, a fully human, anti-interleukin (IL)-17A monoclonal antibody, in patients with psoriatic arthritis (PsA). Methods 42 patients with active PsA fulfilling ClASsification for Psoriatic ARthritis (CASPAR) criteria were randomly assigned (2:1) to receive two intravenous secukinumab doses (10 mg/kg; n=28) or placebo (n=14) 3 weeks apart. The primary endpoint was the proportion of American College of Rheumatology (ACR) 20 responses at week 6 for secukinumab versus placebo (one-sided p<0.1). Results Primary endpoint: ACR20 responses at week 6 were 39% (9/23) for secukinumab versus 23% (3/13) for placebo (p=0.27). ACR20 responses were greater with secukinumab versus placebo at week 12 (39% (9/23) vs 15% (2/13), p=0.13) and week 24 (43% (10/23) vs 18% (2/11), p= 0.14). At week 6, ‘good’ European League Against Rheumatism response was seen in 21.7% (5/23) secukinumab versus 9.1% (1/11) placebo patients. Compared with placebo at week 6, significant reductions were observed among secukinumab recipients for C reactive protein (p=0.039), erythrocyte sedimentation rate (p=0.038), Health Assessment Questionnaire Disability Index (p=0.002) and Short Form Health Survey (SF-36; p=0.030) scores. The overall adverse event (AE) frequency was comparable between secukinumab (26 (93%)) and placebo (11 (79%)) recipients. Six serious AEs (SAEs) were reported in four secukinumab patients and one SAE in one placebo patient. Conclusions Although the primary endpoint was not met, clinical responses, acute-phase reactant and quality of life improvements were greater with secukinumab versus placebo, suggesting some clinical benefit. Secukinumab exhibited satisfactory safety. Larger clinical trials of secukinumab in PsA are warranted.
Human resource management practice and institutional constraints The case of Mozambique

Purpose – This article aims to explore the nature of contemporary HRM practice in Mozambique, and the extent to which “best practice” HRM strategies are likely to emerge, given present institutional realities.Design/methodology/approach – The research was based on an extensive survey of Mozambican employers concentrated in the major urban centres of the country.Findings – The survey revealed little evidence of innovation or of leading edge practices, other than in a small minority of firms. It is concluded that the diffusion of higher value added managerial strategies is only likely to take place in a more supportive institutional context.Practical implications – The failure of innovative HRM techniques to diffuse across the economy, despite heightened external pressures, highlights organizational inertia, including the continued reliance of many firms on low‐paid and low‐skilled workers, and on autocratic paternalism. It remains uncertain whether a more “high value” added path is viable in a context of c.
Benefits of genetically modified herbicide tolerant canola in Western Canada

Commercial production of genetically modified herbicide tolerant (GMHT) canola began in Western Canada in 1997. By 2007, it generated between $374 million and $422 million in net direct and indirect benefits for producers, partly attributed to lower input costs and better weed control. Prior to GMHT canola, weeds were controlled by herbicides and tillage. Much of the tillage associated with GMHT canola production has been eliminated now that 66% of producers use conservation tillage. A reduction in the total number of chemical applications has resulted in a decrease of 1.3 million kg of herbicide active ingredient being applied annually. When comparing canola production in 1995 and 2006, the environmental impact of herbicides applied to canola decreased 53% per hectare and producer exposure to chemicals decreased 56%.
Localization in Europe's Periphery: Tourism Development in Sardinia

As a part of the south Italian Mezzogiorno the island of Sardinia is one of the most peripheral and least favoured regions in the European Union (EU). This article deals with the strategies that have been pursued to restructure the Sardinian economy during the post-war period. In particular, focus is on experiences with local tourism development. After a sketch of the key features of Sardinia, the fruitless top-down strategies of the Italian government to industrialize the island are discussed. After that, the efforts of local parties to promote tourism that builds upon locality-specific assets are analysed. Furthermore, the effects of this localized approach for Sardinia have been generally positive. Moreover, the growing interest among tourists for Sardinia's natural and cultural heritage offers perspectives for bottom-up tourism development as well. Here, however, it is important to balance the short-run benefits of tourism with the possible costs of long-term environmental and socio-cultural degradation. For the future development of Sardinia, therefore, 'eco-tourism' might be an additional tool worth considering in the island's present localized tourism strategy.
Impact of exchange rate regime reform on asset returns in China

Employing monthly data over the period 1999–2010, this paper examines the impact of China's exchange rate regime reform in July 2005 on three major asset markets: house, land, and stocks. We test whether the reform, which switches from a fixed exchange rate regime to a managed floating one, has brought forward structural changes to asset return dynamics. The results suggest that the exchange rate regime switch exerted the most significant impact on house and land returns at the national level, in terms of both returns and their volatilities. In contrast, its impact on China's stock market was moderate, with no structural change being detected in its returns and only weak structural change being found in the dynamics of its volatility. We also find that in comparison with other popular explanatory variables, broad money supply and inflation have the largest explanatory power on housing and land returns in China after the policy reform.
