Does education affect risk aversion? Evidence from the British education reform

Individual risk attitudes are frequently used to predict decisions regarding education. However, using risk attitudes as a control variable for decisions about education has been criticized because of the potential for reverse causality. Causality between risk aversion and education is unclear, and disentangling the different directions it may run is difficult. In this study, we make the first attempt to investigate the causal effects of education on risk aversion by examining the British education reform of 1972, which increased the duration of compulsory schooling from age 15 to age 16. Using regression discontinuity design, we find that this additional year of schooling increases the level of risk aversion, which is contrary to previous findings in the literature, and we also find that this result is particularly strong for individuals with less education. This positive causal effect of education on risk aversion might alleviate concerns regarding the endogeneity/reverse causality issue when using risk aversion as an explanatory variable for decisions about education; the sign would remain credible because the coefficients are underestimated.
Meaning in work and emerging work identities of housing support workers: A quest for a comprehensible plot.

BACKGROUND Work and employees are often marginalized in studies on community-based psychiatric care and support systems. This paper highlights the role of the worker at congregated supported housing for people with severe mental illness (SMI). Housing support workers (HSW) are a fairly new professional role and have developed as a result of major changes in Swedish mental health care and services. The development of new roles is not unproblematic and raises intriguing questions. OBJECTIVE The purpose of this article is to describe housing support workers' experiences of meaning in their work, and in addition illuminate how the work identity of HSWs can be negotiated and constructed. METHODS Four focus group interviews were conducted with a total of 25 participants. Additionally, three follow up sessions were conducted with the same participants. The material consists of employees from four different sites. The intepretation of the material was inspired by a constructionist approach. RESULTS The analysis generated three themes: to do a good job, everyday needs and the formal role. The work identity for HSWs is complex and not easily interpreted. CONCLUSIONS The experience of an unclear assignment affects the description of what is meaningful and important-the work identity and significant affiliations for HSWs. In the long run, this fragmented world can have negative implications for the HSW.
Does Audit Market Concentration Harm the Quality of Audited Earnings? Evidence from Audit Markets in 42 Countries

Audit regulators around the world have expressed concern over market dominance by Big 4 accounting firms and the potential adverse effect it may have on the quality of audited financial statements. We use cross-country variation in the audit market structure of 42 countries to examine two separate aspects of Big 4 dominance: (1) Big 4 market concentration as a group relative to non-Big 4 auditors; and (2) concentration within the Big 4 group in which one or more of the Big 4 firms is dominant relative to the other Big 4 firms. We find that in countries where the Big 4 (as a group) conduct more listed company audits, both Big 4 and non-Big 4 clients have higher quality audited earnings compared to clients in countries with smaller Big 4 market shares. In contrast, in countries where there is a greater concentration within the Big 4 group, we find that Big 4 clients have lower quality audited earnings compared to countries with more evenly distributed market shares among the Big 4. Thus concentration within the Big 4 group appears to be detrimental to audit quality in a country and of legitimate concern to regulators and policymakers. However, Big 4 dominance per se does not appear to harm audit quality and is in fact associated with higher earnings quality, after controlling for other country characteristics that potentially affect earnings quality.
Why Has U.S. Inflation Become Harder to Forecast?

Forecasts of the rate of price inflation play a central role in the formulation of monetary policy, and forecasting inflation is a key job for economists at the Federal Reserve Board. This paper examines whether this job has become harder and, to the extent that it has, what changes in the inflation process have made it so. The main finding is that the univariate inflation process is well described by an unobserved component trend-cycle model with stochastic volatility or, equivalently, an integrated moving average process with time-varying parameters; this model explains a variety of recent univariate inflation forecasting puzzles. It appears currently to be difficult for multivariate forecasts to improve on forecasts made using this time-varying univariate model.
Job Search by Employed and Unemployed Youth

Analysis of data from the New Youth Cohort of the National Longitudinal Survey yields evidence that young unemployed job seekers chose higher levels of search effort (as measured by number of methods used and time spent per method) and lower reservation wages (relative to offered wages) than did comparable employed job seekers in 1981. These differences in search choices at least partly explain differences in search outcomes between the two groups: unemployed searchers apparently were more likely than employed searchers to gain new employment, and the wages they obtained were slightly lower. The author argues that the greater search effort by unemployed job seekers is due to the higher costs of search they bear because of foregone earnings.
The organization of influence on the EC's common agriculturalpolicy: A network approach

The common agricultural policy of the EC with its market regulations is decided at EC level by a multilevel system of government, in which the Commission and the parliamentary parties of the European Parliament play the supranational role and the national ministries of agriculture act as parts of the intergovernmental system of the Council of Ministers. National interest groups have thereby three major access routes to the EC system, first through their national governments, or second indirectly, transmitted by their European peak organizations, or third directly to the supranational EC actors. The network approach is applied to study empirically the densities of access through these various routes. The links between actors in the agricultural policy domain are conceptualized as links for the exchange of resources, the most important resource of a policy domain being the final control of policy decisions. The political actors of the governance system originally hold full control of this valuable resource which they exchange for influence resources possessed by the interest groups, as public support or expert knowledge. Empirically, answers to the network questions depend on the type of resource and the viewpoint of the interviewed actors. An index is developed which indicates the resource flows between actors and the distribution of equilibrium control of policy decisions. It is shown that the national ministers of agriculture depend very much on the support and expertise of their national farmers'; lobby, whereas the Commission relies more on contacts within the political sector itself. Multilevel systems need a lot of political coordination, so that the political actors within such systems, especially at the supranational level, seem to deal first of all with each other and not so much with the demand side of politics, compared to the national ministers of agriculture.
Nitric oxide synthase 3 (NOS3) 4b/a, T-786C and G894T polymorphisms in association with diabetic retinopathy susceptibility: A meta-analysis

Aims: To assess the association between the NOS3 4b/a, T-786C and G894T polymorphisms and diabetic retinopathy (DR) susceptibility. Materials and Methods: Twenty-one studies covering 8,111 subjects were included. The fixed or random effect model used was based on heterogeneity. Results: A significant association of the intron 4a allele in the NOS3 4b/a polymorphism with reduced risk of DR was found in dominant (OR 0.778, 95% CI 0.654–0.926) and additive (OR 0.809, 95% CI 0.698–0.937) models. Subgroup analysis revealed that the intron 4a allele additive model (OR 0.807, 95% CI 0.697–0.935) was associated with DR risk in type 2 diabetic patients. We also found a marginally significant association of the C allele in the T-786C polymorphism with reduced risk of proliferative DR. In contrast, no statistically significant association was observed between the G894T polymorphism and DR risk, either in the overall or subgroup analyses. Conclusions: The intron 4a allele of the 4b/a polymorphism in the eNOS gene has protective effects against DR, especially in type 2 diabetic patients. The C allele of the T-786C polymorphism may be a protective factor for proliferative DR. However, the G894T polymorphism does not appear to influence the development of DR. This conclusion warrants confirmation by further studies.
Mandibular rest position: a reliable position influenced by head support and body posture.

This prospective study was designed to establish how the positions of the molars and the condyles are related to incisor position in the mandibular rest position and how their positions are altered by changing head posture. Measurements of the mandibular rest position were taken on 24 men (age range, 23 to 35) with normal Class I occlusion, skeletal patterns, and temporomandibular joint function. The movements of 5 landmarks (lower incisor, and condyles and molars bilaterally) were tracked from maximum intercuspation into 4 independent rest positions (upright supported, upright unsupported, supine supported, and supine unsupported) using an optoelectric (Optotrak; Northern Digital, Waterloo, Ontario, Canada) computer system. The positions were based on minimal electromyographic and verbal instructions to swallow, lick the lips, and say "Mississippi. " The results showed significant (P <.01) movements of the incisors, the molars, and the condyles into each of the 4 rest positions. Movements of the molars and the condyles into the supported upright posture and the unsupported upright posture differed slightly but significantly because of greater movement into the supported posture. Patterns of mandibular movement were entirely different between the upright and the supine rest positions; the mandible rotated anteriorly in the supine position and posteriorly in the upright position. We concluded that movement into the mandibular rest position from the intercuspal position is not a simple opening rotation of the mandible, and that the pattern of movement is influenced by head support and body postures.
Hubs and High Fares: Dominance and Market Power in the U.S. Airline Industry

This article estimates the importance of route and airport dominance in determining the degree of market power exercised by an airline. The results indicate that an airline's share of passengers on a route and at the endpoint airports significantly influences its ability to mark up price above cost. The high markups of a dominant airline, however, do not create much of an "umbrella" effect from which carriers with smaller operations in the same markets can benefit. The article suggests a number of possible explanations for this asymmetry.
Home Country Determinants of Outward FDI from Developing Countries

This article examines various home country determinants of outward FDI from developing economies, which have received limited attention in empirical studies. The role of home country determinants is investigated for a large sample of developing economies, as against a handful of developing economies, for the most recent period, 1996–2010, using a panel data econometric framework. The results indicate that source country’s level of economic development, globalisation, political risk and science and technology investments contribute significantly to outward FDI from developing countries. While outward FDI might be unavoidable in the course of economic development and globalisation, developing countries need to emphasise improving political governance in order to prevent capital outflow arising out of high domestic political risk. On the flip side, science and technology investments could contribute to higher outward FDI, thereby yielding complementary benefits of internationalisation in the long-run. Thus, given the evolving role of developing countries in the global economic scenario, a balance between domestic and international investments is crucial for them to harness the benefits of globalisation, which can be achieved through suitable governance and policy reforms in specific fields.
Longevity insurance markets and Money's worth ratios in Korea*

Abstract The rare annuitization, thin immediate annuity market, and date limitation have prevented the attempts to analyze the longevity insurance market in Korea. The purpose of this paper is to examine the relative value of Korean annuity rates to theoretical ones and to provide a new evidence on the function of the voluntary annuity market in terms of the money's worth ratio (MWR). Our results show that the immediate annuity market in Korea is reasonably efficient. For example, the money's worth ratio of an immediate annuity of a 10-year guarantee period for a 65-year-old male is estimated to be about 0.8 with the general population mortality rate, while it improves to 0.9 with the annuitant mortality table. Average MWR is similar to that of other countries with thin annuity market, which show that annuitants in Korea pay a comparable cost to that in other countries.
Impact of Water Content on the Electrical Behavior of Epoxy Insulators

Polymers are widely used in indoor insulation. We analyze three epoxy samples with varying matrix and filler properties to determine the influence of water on their insulating properties. We observed a strong dependency of the leakage current and the sample temperature, under electrical stress, on the amount of absorbed water. Tri- hydrated alumina filler reduced the leakage current and temperature rise under electrical stress.
Hypervascular hepatocellular carcinoma 1 cm or smaller in patients with chronic liver disease: characterization with gadoxetic acid-enhanced MRI that includes diffusion-weighted imaging.

OBJECTIVE The purpose of this study was to determine the finding most predictive for characterizing hypervascular hepatocellular carcinoma (HCC) measuring 1 cm or less at gadoxetic acid-enhanced MRI that includes diffusion-weighted images. MATERIALS AND METHODS In this retrospective study, between May 2008 and June 2009, 66 patients with 108 hypervascular HCCs 1 cm or smaller underwent gadoxetic acid-enhanced 3-T MRI that included diffusion-weighted images. The diagnosis of HCC was determined by surgical resection in 32 cases, percutaneous biopsy in three cases, or interval growth to larger than 1 cm on follow-up images in accordance with the American Association for the Study of Liver Diseases guidelines in 73 cases. MRI findings of HCC and 33 benign hypervascular lesions in a control group were analyzed by two radiologists in consensus. They based their assessments on the presence or absence of the following five findings: hyperintensity on T2-weighted images, hyperintensity on diffusion-weighted images with low b values, washout pattern, capsular enhancement, and hypointensity on gadoxetic acid-enhanced hepatobiliary phase images. The findings were compared by use of univariate and multivariate analyses. RESULTS No HCC with capsular enhancement was found. Fifty-seven HCCs (52.8%) had four findings, 36 (33.3%) had three, nine (8.3%) had two findings, and six (5.6%) had one finding. Univariate analysis showed significant differences between the HCC and control groups with respect to four findings (p < 0.0001). Multivariate analysis showed that hyperintensity on T2-weighted (p < 0.0001) and diffusion-weighted (p = 0.0081) images were statistically significant MRI findings for predicting HCC. CONCLUSION Hyperintensity on both T2- and diffusion-weighted images is helpful in the diagnosis of hypervascular HCC smaller than 1 cm in diameter.
Age Differences in Hindsight Bias: The Role of Episodic Memory and Inhibition

Background/Study Context: After learning an event’s outcome, people’s recollection of their former prediction of that event shifts towards the actual outcome. This hindsight bias (HB) phenomenon tends to be stronger in older compared with younger adults; however, it is unclear whether age-related changes in other cognitive abilities mediate this relationship. Methods: Sixty-four younger adults (Mage = 20.1; range = 18–25) and 60 community-dwelling older adults (Mage = 72.5; range = 65–87) completed a memory design HB task. Two aspects of HB, its occurrence and magnitude, were examined. Multiple regression and mediation analyses were conducted to determine whether episodic memory and inhibition mediate age differences in the occurrence and magnitude of HB. Results: Older adults exhibited a greater occurrence and magnitude of HB as compared with younger adults. The present findings revealed that episodic memory and inhibition mediated age-related increases in HB occurrence. Conversely, neither cognitive ability mediated age-related increases in HB magnitude. Conclusion: Older adults’ susceptibility to the occurrence of HB is partly due to age-related declines in episodic memory and inhibition. Conversely, age differences in the magnitude of HB appear to be independent of episodic memory and inhibition. These findings have important implications for understanding the mechanisms by which susceptibility to HB changes across the adult life span.
Transforming growth factor‐beta1 inhibits tissue engineering cartilage absorption via inducing the generation of regulatory T cells

The objective of the present study was to explore the mechanisms of transforming growth factor (TGF)‐β1 inhibiting the absorption of tissue engineering cartilage. We transfected TGF‐β1 gene into bone marrow mesenchymal stem cells (BMMSCs) and co‐cultured with interferon (IFN)‐γ and tumour necrosis factor (TNF)‐α and CD4+CD25− T lymphocytes. We then characterized the morphological changes, apoptosis and characterization of chondrogenic‐committed cells from TGF‐β1+BMMSCs and explored their mechanisms. Results showed that BMMSCs apoptosis and tissue engineering cartilage absorption in the group with added IFN‐γ and TNF‐α were greater than in the control group. In contrast, there was little BMMSC apoptosis and absorption by tissue engineering cartilage in the group with added CD4+CD25− T lymphocytes; Foxp3+T cells and CD25+CD39+ T cells were found. In contrast, no type II collagen or Foxp3+T cells or CD25+CD39+ T cells was found in the TGF‐β1–BMMSC group. The data suggest that IFN‐γ and TNF‐α induced BMMSCs apoptosis and absorption of tissue engineering cartilage, but the newborn regulatory T (Treg) cells inhibited the function of IFN‐γ and TNF‐α and protected BMMSCs and tissue engineering cartilage. TGF‐β1not only played a cartilage inductive role, but also inhibited the absorption of tissue engineering cartilage. The pathway proposed in our study may simulate the actual reaction procedure after implantation of BMMSCs and tissue engineering cartilage in vivo. Copyright © 2013 John Wiley & Sons, Ltd.
Intra- and intersectoral effects in environmental disclosures: evidence for legitimacy theory?

Environmental disclosures were recorded from the annual reports of a sample of ten UK FTSE 100 companies in five sectors between 1974 and 2000. ‘Environmental sensitivity’ was employed as a proxy for corporate vulnerability to environmental concern, and intra- and intersectoral differences were tested for in the belief that difference in industry response will signify differing perceptions on the need to provide voluntary disclosure and hence restore or maintain legitimacy. Intrasectoral agreements at given points in time were also taken to be evidence for legitimacy theory in that more than one company in a sector perceived a need to change disclosure behaviour at the same time. Legitimacy theory as an explicator for variability in environmental disclosure is supported. Copyright © 2003 John Wiley & Sons, Ltd and ERP Environment.
Genetic transformation of Streptococcus pneumoniae by heterologous plasmid deoxyribonucleic acid

A number of heterologous plasmid deoxyribonucleic acids (DNAs) coding for erythromycin, tylosin, lincomycin, tetracycline, or chloramphenicol resistance have been introduced into Streptococcus pneumoniae via genetic transformation with frequencies that varied between 10(-5) to as high as 5 x 10(-1) per colony-forming unit. Transformation with plasmid DNA required pneumococcal competence, was competed by chromosomal DNA, and showed a saturation at about 0.5 micrograms/ml (with a recipient population of 3 x 10(7) colony-forming units of competent cells per ml). Plasmid transformation did not occur with a recipient strain, 410, defective in endonuclease I activity and in chromosomal genetic transformation. All erythromycin-resistant transformants examined contained covalently closed circular DNA with the same electrophoretic mobility on agarose gels as the donor DNAs, and when examined in detail the plasmid reisolated from the transformants had the same restriction patterns and the same specific transforming activity as the donor DNA. In the cases of two plasmids examined in detail--pAM77 and pSA5700 Lc9--most of the transforming activity was associated with DNA monomers; DNA multimers present in pSA5700 Lc9 also had biological activity. An unexpected finding was the demonstration of transformation (2 x 10(-5) per colony-forming unit) with plasmid DNAs linearized by treatment with S1 nuclease or with restriction endonucleases.
Students’ Perception of the Role of Counsellors in the Choice of a Career: a study of the Mfantseman Municipality in Ghana

This study investigated students’ perception of the role of counsellors in the choice of career using two schools in the Mfantseman Municipality in the Central Region. The study aimed at finding out the available counselling services in schools, the frequency of access to counselling in schools, and the perception students hold about the role of counsellors in the choice of careers. The descriptive research design was used in this study. Student respondents numbered 349 while 2 counsellors were involved in the study. Questionnaires and an interview guide were used to gather the necessary data for the study. The study revealed that counselling services are available in schools and include educational, vocational, and person-social counselling. Secondly, the study found that students had access to counselling but their frequency of access was inhibited by counsellor characteristics and other factors. Lastly, the study uncovered that students thought counsellors to be central to the process of making career choices. The government, Ghana Education Services, and school authorities should give much heed to counselling especially career guidance by making resources available to counsellors for work. Career guidance programmes should be routinized in schools for greater benefits to students. Counsellors should also endeavour to seek opportunities for skill upgrade and higher training so that they can become more relevant to the needs of students. 479510173
