Studies of the preceding crop effect of ley in ecological agriculture.

Two field experiments were conducted from 1991 to 1996 on clay soils in central Sweden to provide information for improving soil fertility, minimizing N leaching, and increasing the benefits of ley to subsequent crops in organic farming. The results show that it is possible to calculate the amount of N mineralized during the 2-year period following incorporation of ley-crop residues, based on the proportion of incorporated organic matter stabilized in the more resistant humus fractions (i.e., the humification coefficient, calculated to be 35-40%), C:N ratios of the ley biomass, and ley age (humification appears to be higher in older crop residues). The fractions of potentially mineralizable N that are actually mineralized in the first and second years after ley incorporation vary depending on ley age and botanical composition and climatic conditions.
Institutional Investors and Equity Prices

This paper analyzes institutional investors' demand for stock characteristics and the implications of this demand for stock prices and returns. We find that "large" institutional investors nearly doubled their share of the stock market from 1980 to 1996. Overall, this compositional shift tends to increase demand for the stock of large companies and decrease demand for the stock of small companies. The compositional shift can, by itself, account for a nearly 50 percent increase in the price of large-company stock relative to small-company stock and can explain part of the disappearance of the historical small-company stock premium.
Signaling and the Valuation of Unseasoned New Issues

This paper is an empirical examination of the relation between firm value and two potential actions by entrepreneurs attempting to signal to investors information about otherwise unobservable firm features. The signals investigated are the proportion of equity ownership retained by entrepreneurs and the dividend policy of the firm; both signals are hypothesized to be positively related to firm value. Using a sample of unseasoned new equity issues, the empirical results are consistent with the entrepreneurial ownership retention hypothesis, but the dividend signaling hypothesis is rejected.
Simultaneous Measurement of Multiple Mechanical Properties of Single Cells Using AFM by Indentation and Vibration

Objective: The mechanical properties of cells, which are the main characteristics determining their physical performance and physiological functions, have been actively studied in the fields of cytobiology and biomedical engineering and for the development of medicines. In this study, an indentation-vibration-based method is proposed to simultaneously measure the mechanical properties of cells in situ, including cellular mass (m), elasticity (k), and viscosity (c). Methods: The proposed measurement method is implemented based on the principle of forced vibration stimulated by simple harmonic force using an atomic force microscope (AFM) system integrated with a piezoelectric transducer as the substrate vibrator. The corresponding theoretical model containing the three mechanical properties is derived and used to perform simulations and calculations. Living and fixed human embryonic kidney 293 (HEK 293) cells were subjected to indentation and vibration to measure and compare their mechanical parameters and verify the proposed approach. Results: The results that the fixed sample cells are more viscous and elastic than the living sample cells and the measured mechanical properties of cell are consistent within, but not outside of the central region of the cell, are in accordance with the previous studies.Conclusion: This work provides an approach to simultaneous measurement of the multiple mechanical properties of single cells using an integrated AFM system based on the principle force vibration and thickness-corrected Hertz model. Significance: This study should contribute to progress in biomedical engineering, cytobiology, medicine, early diagnosis, specific therapy and cell-powered robots.
Coatomer-dependent protein delivery to lipid droplets

Lipid droplets (LDs) are cytoplasmic organelles that store neutral lipids for use as an energy supply in times of nutrient deprivation and for membrane assembly. Misregulation of LD function leads to many human diseases, including lipodystrophy, obesity and neutral lipid storage disorders. A number of proteins have been shown to localize to the surface of lipid droplets, including lipases such as adipose triglyceride lipase (ATGL) and the PAT-domain proteins ADRP (adipophilin) and TIP47, but the mechanism by which they are targeted to LDs is not known. Here we demonstrate that ATGL and ADRP, but not TIP47, are delivered to LDs by a pathway mediated by the COPI and COPII coatomer proteins and their corresponding regulators.
Examining Factors that Influence School Administrators' Responses to Large-Scale Assessment.

This study examined factors at the school, district, and provincial level that influenced school administrators’ responses to large-scale assessment. To understand administrators’ perspectives, 5 secondary and 4 elementary administrators from a suburban school district in southern Ontario, Canada were interviewed. Key factors noted by administrators included school improvement planning (elementary versus secondary), departmental structures and teacher resistance within schools, lack of professional development opportunities, inadequate resources and direction from districts, ministry initiative overload, lack of an easily identifiable provincial assessment and evaluation policy document, and pressure to reach provincial achievement targets. The findings underscore the need for greater initial and ongoing professional development for school administrators as well as more thoughtful support from district leaders and provincial policy-makers.
Are the Beneficial Effects of Ischemic Preconditioning on Performance Partly a Placebo Effect?

Abstract The acute effect of ischemic preconditioning (IPC) on the maximal performance in the 100-m freestyle event was studied in recreational swimmers. 15 swimmers (21.0±3.2 years) participated in a random crossover model on 3 different days (control [CON], IPC or SHAM), separated by 3–5 days. IPC consisted of 4 cycles of 5-min occlusion (220 mmHg)/5-min reperfusion in each arm, and the SHAM protocol was similar to IPC but with only 20 mmHg during the occlusion phase. The subjects were informed that both maneuvers (IPC and SHAM) would improve their performance. After IPC, CON or SHAM, the volunteers performed a maximal 100-m time trial. IPC improved performance (p=0.036) compared to CON. SHAM performance was only better than CON (p=0.059) as a tendency but did not differ from IPC performance. The individual response of the subjects to the different maneuvers was very heterogeneous. We conclude that IPC may improve performance in recreational swimmers, but this improvement could mainly be a placebo effect.
Firm performance, corporate governance and executive compensation in high-tech businesses

Most previous researchers believe that the connection between executive compensation and company performance will resolve agency problems between the principal and the agent. However, this method will lead to an unlimited increase in agency costs and make executives pay attention to only short-term company performance, therefore ignoring long-term growth. Thus, this research includes firm performance and two other mechanisms, institutional investors and boards directors, to assess the impact of these on executive compensation. The samples used in this study were listed companies in high-tech businesses during 2004–2006. This article's conclusion is as follows: (1) executive compensation as a control mechanism to reduce the agency problem is applied efficiently to high-tech businesses; (2) executive compensation will be lower when institutional investors' control is relatively effective. This explains the substitutive characteristic between pay-for-performance and control mechanisms from corporate governance.
Immigrant Performance in the Labour Market: Bonding and Bridging Social Capital

To what extent can different forms of social capital help immigrants make headway on the labour market? An answer to this pressing question begins here. Taking the Netherlands and Germany as case studies, the book identifies two forms of social capital that may work to increase employment, income and occupational status and, conversely, decrease unemployment. New insights into the concepts of bonding and bridging arise through quantitative research methods, using longitudinal and crosssectional data. Referring to a dense network with 'thick' trust, bonding is measured as family ties, co-ethnic ties and trust in the family. Bridging is seen in terms of interethnic ties, thus implying a crosscutting network with 'thin' trust. Immigrant Performance in the Labour Market reveals that although bonding allows immigrants to get by, bridging enables them to get ahead.
A case study of DIY ICT

Purpose – This paper seeks to present a case study of a rural Do It Yourself (DIY) Information and Communication Technology (ICT) project in a Japanese depopulated rural community.Design/methodology/approach – The paper consists of two parts. First, the technology that enables the project is presented together with policy considerations about why such a technology had to be deployed. An analysis of the results from surveys and interviews is then presented.Findings – In order to achieve sustainable development of a rural ICT project, which is the key to enabling economic development, it is essential to involve residents' participation. A test‐bed DIY project was constructed in a Japanese rural community in 2004, and surveys were conducted in 2004 and 2006 in order to identify residents' needs and awareness of ICT, determine the information literacy level, and evaluate the attitude toward the acceptance of ICT. Also, individual interviews were conducted to look at the qualitative side of residents' percepti.
Equivalent osteoblastic differentiation function of human mesenchymal stem cells from rheumatoid arthritis in comparison with osteoarthritis.

OBJECTIVE To evaluate the osteoblastic differentiation of human mesenchymal stem cells (hMSCs) in patients with RA. METHODS Heparinized bone marrow aspirate was obtained from patients with OA and RA. Mononuclear cells were cultured for 2 weeks and a colony-forming assay was performed. The phenotype of cells was analysed by flow cytometry. Passage 2 cells were cultured with beta-glycerophosphate (bGP) in the control group and bGP, ascorbic acid and dexamethasone in the differentiation group. After 2 weeks, ALP staining and activity were performed. After 3 weeks, Alizarin Red S assay was performed. Total RNA was extracted from cells cultured for 2 and 3 weeks. Gene expression of bone formation factor was examined by real-time PCR. RESULTS The phenotype of cells was identical in both OA and RA and the content was thought to be hMSCs. The results of ALP activity and Alizarin Red S assay showed higher levels in the differentiation group for both OA and RA samples compared with the control group. The results of a colony-forming assay were identical in both OA and RA samples. Gene expression in the differentiation group was higher than in the control group in both OA and RA samples. There was no significant difference between OA and RA samples in all experiments. CONCLUSION The function of osteoblastic differentiation of hMSCs is similar between OA and RA.
Website ratings of physicians and their quality of care.

Website Ratings of Physicians and Their Quality of Care One-third of consumers in the United States who consulted physician website ratings reported selecting and/or avoiding physicians because of these ratings.1 However, little is known about the validity of these ratings. Available studies have focused mostly on hospital website ratings or non-US website ratings.2,3 We partially address this gap by measuring the association between US physician website ratings and traditional quality measures (QMs) of clinical and patient experience.
Service failure and recovery: evidence from the hotel industry

This paper is focused on service failure and recovery in the hotel industry in the UK. The objectives of the research were to: assess the types and magnitude of service failures experienced by hotel guests; evaluate the service recovery strategies used by hotels and their effectiveness; and discover whether or not there were differences in attitudes and behaviour between business and leisure guests. Data were collected from a sample of guests in a four‐star hotel. Discussion of the findings leads to some suggestions for improvements for hotel management.
Deconstructing the Theory of Comparative Advantage

This article critically examines the theory of comparative advantage, which underlies the wide-spread support of worldwide trade liberalisations. Both the classical and neoclassical formulations of it are shortly discussed and its essential assumptions are scrutinised. These include the international immobility of capital and labour, balanced trade, the existence of an adjustment mechanism which is responsible for the transformation of comparative production advantages into absolute price advantages, full employment and the perception of international trade as a static and harmonious phenomenon. It is shown that all these assumptions are neither theoretical valid nor do they coincide with empirical research. The whole rationale why international trade exists according this theory is deficient. The New Trade Theory, which claims to enhance the theory of comparative advantage, is unconvincing as a complement. It is concluded that the theory of comparative advantage should be dismissed. International trade theory, by relying on this theory, risks ignoring the most relevant and important elements with regard to international trade. The deficiencies of the theory of comparative advantage are especially crucial for trade policies that are derived from this theory, which is discussed with reference to the WTO and its ongoing Doha Round.
STUDENT PERSPECTIVES OF THE NATURE, EFFECTIVENESS, AND VALUE OF THE MINNESOTA FARM BUSINESS MANAGEMENT EDUCATION PROGRAM

The Minnesota Farm Business Management Education Program provides business management education to farmers. Over 100 instructors currently provide instruction that assists 4,000 to 4,350 farmers annually in meeting their financial, family, and personal goals. This evaluation study sought to determine how the contemporary students viewed selected instructional activities, elements, and program outcomes. The results show that individualized instruction and telephone communications were the highest-ranking instructional methods and instructional media, respectively. Instruction relating to the practice of keeping and analyzing records, and making management decisions were highly desired. The effectiveness of the FBM program in delivering selected instructional topics, activities and/or benefits was highly related to the level of importance placed upon each topic, activity, and benefit by the students. The students were very satisfied with the program as evident by the positive nature of their recommendations to potential students and their belief that they receive an annual improvement in net farm income of nearly $5,000.
Creating a profession of educators with the living-theories of master and doctor educators

In our last paper in GEI we presented an argument for teachers to engage in Living Educational Theory research as Continuing Professional Development. In this paper we extend our analysis to show how this can empower educators to improve their practice and, by offering as a gift the knowledge they generate in the process, contribute to the creation of a profession of educators. The extension is grounded in the idea of enhancing professionalism in education through recognising and accrediting accounts of living-educational-theories as knowledge generated by professional practitioners as master and doctor educators. We distinguish Living Educational Theory research from a living-educational-theory. Living Educational Theory research refers to the conceptual principles that distinguish the research approach. A living-educational-theory is a values-based explanation offered by an individual of their educational influence in their own learning, the learning of others and the learning of social formations. It is argued that for this knowledge to be legitimated by universities, in the form of accredited awards, an extension and transformation will be required in the dominating forms of knowledge. It is also argued that educators teaching in continuing professional development programmes need to develop their talents, knowledge and expertise by researching their own practice in the same way as the teachers they are supporting. In doing so they exemplify an educational pedagogy appropriate to providing gifted education internationally for students of any age.
Income, Housing Wealth and Gender Inequality

Gender inequalities in income are relatively widely documented, but their realisation in the housing system is less well understood. This paper examines the relationship between incomes, access to housing and housing costs among widowed, divorced, separated and never-married single people in Australia. While the relative financial advantages of single men are sustained throughout the housing system, there is some evidence that gender discrepancies in income are reduced once housing costs are taken into account. Lone mothers, however, fare least well, and face a disproportionate loss of disposable income through housing expenditures.
Acute exposure to pure cylindrospermopsin results in oxidative stress and pathological alterations in tilapia (Oreochromis niloticus)

Cylindrospermopsin (CYN) is increasingly recognized as a potential threat to drinking water safety, due to its ubiquity. This cyanotoxin has been found to cause toxic effects in mammals, and although fish could be in contact with this toxin, acute toxicity studies on fish are nonexistent. This is the first study showing that single doses of CYN pure standard (200 or 400 μg CYN/kg fish bw) by oral route (gavage) generate histopathological effects in fish (Tilapia—Oreochromis niloticus) exposed to the toxin under laboratory condition. Among the morphological changes, disorganized parenchymal architecture in the liver, dilated Bowman's space in the kidney, fibrolysis in the heart, necrotic enteritis in the intestines, and hemorrhages in the gills, were observed. Moreover, some oxidative stress biomarkers in the liver and kidney of tilapias were altered. Thus, CYN exposure induced increased protein oxidation products in both organs, NADPH oxidase activity was significantly increased with the kidney being the most affected organ, and decreased GSH contents were also detected in both organs, at the higher dose assayed. © 2012 Wiley Periodicals, Inc.

The role of the intestinal microbiota in the pathogenesis of necrotizing enterocolitis

Abstract Development of necrotizing enterocolitis (NEC) requires a susceptible host, typically a premature infant or an infant with congenital heart disease, enteral feedings and bacterial colonization. Although there is little doubt that microbes are critically involved in the pathogenesis of NEC, the identity of specific causative pathogens remains elusive. Unlike established normal adult gut microbiota, which is quite complex, uniform, and stable, early postnatal bacterial populations are simple, diverse, and fluid. These properties complicate studies aimed at elucidating characteristics of the gut microbiome that may play a role in the pathogenesis of NEC. A broad variety of bacterial, viral, and fungal species have been implicated in both clinical and experimental NEC. Frequently, however, the same species have also been found in physiologically matched healthy individuals. Clustered outbreaks of NEC, in which the same strain of a suspected pathogen is detected in several patients suggest, but do not prove, a causative relationship between the specific pathogen and the disease. Studies in Cronobacter sakazakii, the best characterized NEC pathogen, have demonstrated that virulence is not a property of a bacterial species as a whole, but rather a characteristic of certain strains, which may explain why the same species can be pathogenic or non-pathogenic. The fact that a given microbe may be innocuous in a full-term, yet pathogenic in a pre-term infant has led to the idea of opportunistic pathogens in NEC. Progress in understanding the infectious nature of NEC may require identifying specific pathogenic strains and unambiguously establishing their virulence in animal models.
Wrongdoing, Whistle-Blowing, and Retaliation in the U.S. Government

Much of the unethical behavior occurring in modern organizations that comes to light is first identified and reported by insiders: organization members who are willing to blow the whistle. Data from surveys of federal employees conducted since 1980 by the U.S. Merit Systems Protection Board (MSPB) have been analyzed by researchers. These studies have taught us quite a lot about whistle-blowing, but we still need to learn much more. We present here a summary of results from research on the incidence of wrongdoing and whistleblowing, predictors of whistle-blowing, predictors of retaliation against whistle-blowers, and predictors of overall effectiveness of whistle-blowers in getting wrongdoing stopped. We describe key findings and suggest new directions for future research and policy to address the critical questions still remaining concerning whistle-blowing.
Estimating country-specific environmental Kuznets curves from panel data: a Bayesian shrinkage approach

Designing an efficient global climate policy turns out to be a difficult yet crucial task since there are noteworthy cross-country differences in energy and carbon intensities. In this article, the environmental Kuznets curve (EKC) hypothesis is tested for carbon dioxide (CO2) emissions, and as a modelling technique, the iterative Bayesian shrinkage procedure is employed to handle the cross-country differences. The results suggest that first the EKC hypothesis is rejected for 47 out of the 51 countries considered when the heterogeneity in countries’ energy efficiencies and cross-country differences in the CO2 emissions trajectories are accounted for; second, a classification of the results with respect to the development levels of the countries concerned reveals that the emergence of an overall inverted U-shaped curve is due to the fact that in high-income countries increase in gross domestic product (GDP) decreases emissions, while in low-income countries emissions and GDP are positively correlated.
Visioning with the Public: Incorporating Public Values in Landscape Planning

This article focuses on the incorporation of values in visioning, an early stage of landscape planning from a social learning perspective. After an introduction of social learning in planning and visioning directed at expert knowledge and public values, two visioning cases are evaluated. The authors assess methods of making public values manifest and ways to include them in the visioning process. The cases show that surveys, semi-structured interviews and the emphasis on values during the visioning exercise itself were suitable methods to acquaint civilians with both their own values and those of others. The explicit values made communication more effective and enhanced social learning. In both cases, the civilians proved to be capable of expressing their values and visioning in conjunction with experts. The article concludes with the impact of integrating values in landscape planning, the learning process that emerged between the stakeholders and the implication of the findings for visioning practices elsewhere.
