Gender-Typical Responses to Sexual and Emotional Infidelity as a Function of Mortality Salience Induced Self-Esteem Striving

The authors propose that gender-differentiated patterns of jealousy in response to sexual and emotional infidelity are engendered by the differential impact of each event on self-esteem for men and women. Study 1 demonstrated that men derive relatively more self-esteem from their sexlives, whereas women’s self-esteem is more contingent on romantic commitment. Based on terror management theory, it is predicted that if gender-differentiated responses to infidelity are motivated by gender-specific contingencies for self-esteem, they should be intensified following reminders of mortality. In Study 2, mortality salience (MS) increased distress in response to sexual infidelity for men and emotional infidelity for women. Study 3 demonstrated that following MS, men who place high value on sexin romantic relationships exhibited greater distress in response to sexual infidelity, but low-ex-value men’s distress was attenuated. The authors discuss the implications for evolutionary and self-esteem-based accounts of jealousy as well as possible integration of these perspectives.
How and Why Educators Use Twitter: A Survey of the Field

Abstract While the microblogging service Twitter is increasingly popular among educators and offers numerous affordances for learning, its relationship with formal education systems remains complicated by generally ambivalent educator attitudes and institutional policies. To better understand the role Twitter plays in education, we conducted a survey of 755 K–16 educators that yielded quantitative and qualitative data concerning how and why the medium is used. Respondents reported intense and multifaceted utilization of the service, with professional development (PD) uses more common than interactions with students or families. Educators valued Twitter's personalized, immediate nature, and the positive and collaborative community it facilitated. Many cited Twitter's role in combating various types of isolation and described it as superior to traditional professional development. We finish by discussing implications for educators, researchers, and educational institutions.
Internal Fixation of Proximal Humerus Fractures Using the Screw-Tension Band Technique

Summary: Many of the current techniques of internal fixation of proximal humerus fractures use tension band wires to achieve secure fixation, allowing immediate postoperative exercise of the affected limb. In addition, the use of a cancellous lag screw placed from the humeral shaft into the humeral head may have several advantages. In particular, this lag screw does not violate the subacromial space and provides initial stability between the head and shaft, which facilitates placement of the tension band wires. This technique was used in 13 patients whose average age was 71 years (range 54-86). Follow-up averaged 20 months. Eight patients had two-part fractures and five patients had three-part fractures. This technique used a deltopectoral approach with manual impaction of the humeral head and shaft. A 6.5-mm AO screw was used for lag screw fixation in addition to two 18-gauge tension band wires: one placed through the tuberosities and one under the rotator cuff tendons. Passive range of motion of the involved shoulder was begun within the first postoperative week, and active range of motion and strengthening were allowed after the fourth postoperative week. At follow-up patients were evaluated for range of motion, function, pain, and radiographic appearance of the fracture. Average forward flexion was 160°, external rotation was 46°, and internal rotation was to the 10th thoracic vertebra. According to the functional scale proposed by Hawkins, 10 of the 13 patients had achieved a good result. Two of the remaining patients had a fair score, and one had a poor outcome. Five of the 13 patients reported occasional, mild pain. Radiographically there was one instance of slight varus settling. There were no instances of avascular necrosis. In one patient, one tension band wire had broken; however, revision was not necessary. Tension band wiring combined with lag screw fixation afforded sufficient fracture stability to allow early, aggressive rehabilitation in this elderly patient cohort. As a method of internal fixation, this technique may have particular advantages in elderly osteoporotic patients.
The impact of regional entrepreneurial contexts upon enterprise education

Growing evidence demonstrates the significance of regional contexts in shaping entrepreneurship capital, and the importance of this for entrepreneurial knowledge and learning. We report the findings of a six-country study into enterprise education within schools, in less and more developed European regions. The fieldwork exposes differences by regional type, across enterprise education objectives, outcomes, resources and social constructions of the entrepreneur. Regional context can be seen as developing local narratives of entrepreneurial identities and careers. Context-setting within schools takes the form of storying entrepreneurship, of presenting credible local identities and expressing the meaning of entrepreneurship for these communities.
Comparing an experimental agent to a standard agent: relative merits of a one-arm or randomized two-arm Phase II design

Background Phase II clinical trials in cancer are used to assess whether a new agent has sufficiently promising efficacy to proceed on to a larger definitive study comparing the new agent to a standard agent. Purpose A crucial issue in determining the usefulness of a one-arm design is the uncertainty of the historical response rate of the standard therapy. Therefore, we contrast the usual one-arm design of a Phase II trial with a randomized two-arm design that uses the same number of patients. Methods We use simulations and analytical approximations to compare the two designs under a range of realistic values for the historical rate uncertainty and a range of treatment effects. We also extend the simulation model to compare the efficiency of the two designs in settings where multiple Phase II studies are used to make decisions about moving on to a Phase III study. Results For a one-arm design the probability of correctly identifying an effective experimental agent tends to be at least 0.7 in the cases considered, with the corresponding value for a randomized two-arm design within 0.05-0.10 above or below the one-arm design. An increase in total sample size from 30 patients to 80 patients tends to increase the probability of correctly identifying an effective experiment agent more in the two-arm design than the the one-arm design, particularly when the uncertainty in the historical response rate is large. Limitations These results for binary response measures are derived from the specific scenarios and assumptions considered in the simulation study and may not apply to situations outside the range considered. Conclusions We find that a one-arm design is preferred for small sample sizes, but a two-arm design may be preferred with larger sample sizes or if the uncertainty in the historical response rates is large.
Firm Level Performance Implications of Nonmarket Actions

This article draws from theories of business-government relations and Austrian economics to develop a model relating firm performance to the firm’s market and nonmarket actions. Nonmarket actions represent one mechanism for the implementation of firm strategies. The model is tested using an original data set covering airlines serving international routes in the North Atlantic region. Results suggest that nonmarket actions have a positive and significant impact on performance, measured in three ways: profits, market share, and capacity utilization.
A nova agenda internacional de segurança põe a democracia brasileira em risco

The international security agenda in the Post-Cold War world has changed. New threats, mostly internal, rather than external, have gained importance and challenge traditional theories of security. This article analyzes official documents produced by national and international actors. It is possible to identify political and legal incentives for the participation of military forces in police activities. This, however, might endanger a democratic regime.
Explaining Japan&Apos;S Innovation and Trade: a Model of Quality Competition and Dynamic Comparive Advantage

In this paper, I develop a model of dynamic comparative advantage based on endogenous innovation. Firms in each of two countries devote resources to R&D in order to improve the quality of high-technology products. Research successes generate profit opportunities in the world market. The model predicts that a country such as Japan, with abundance of skilled labor and scarcity of natural resources, will specialize relatively in industrial innovation and in the production of high-technology goods. Data are provided to support this prediction. I use the model to explore the effects of R&D subsidies, production subsidies and trade policies on the long-run rates of innovation in trade partner countries and on the long-run pattern of trade.
Consumer Heterogeneity in the Willingness to Pay for Local and Organic Food

Due to growth and changing distribution channels for organic food in Germany, there is some concern that organic food is losing authenticity. Contrarily, local food production is seen as a new trend and is gaining market share. This article analyzes whether those alternative concepts of organic and local food production rather support or threaten each other in consumers’ choice. Results of a Bavarian survey, including a choice experiment for bread, beer, and milk on the attributes price, brand, local, and organic, are analyzed using a mixed logit model. Willingness-to-pay estimations confirm the importance of local production to the surveyed consumers, especially in interaction with organic production, leading to the conclusion that the two production methods can support each other in achieving price premiums. The estimated standard deviations show significant heterogeneity of the parameters for all three products for most attributes.
Incentives, Selection and Productivity in Labor Markets: Evidence from Rural Malawi

An observed positive relationship between compensation and productivity cannot distinguish between two channels: (1) an incentive effect and (2) worker selection. We use a simplified Becker-DeGroot-Marschak mechanism, which provides random variation in piece rates conditional on revealed reservation rates, to separately identify the two channels in the context of casual labor markets in rural Malawi. A higher piece rate increases output in our setting, but does not attract more productive workers. Among men, the average worker recruited at higher piece rates is actually less productive. Local labor market imperfections appear to undermine the worker sorting observed in well-functioning labor markets.
A Compact Convolutional Neural Network for Textured Surface Anomaly Detection

Convolutional neural methods have proven to outperform other approaches in various computer vision tasks. In this paper we apply the deep learning technique to the domain of automated visual surface inspection. We design a unified CNN-based framework for segmentation and detection of surface anomalies. We investigate whether a compact CNN architecture, which exhibit fewer parameters that need to be learned, can be used, while retaining high classification accuracy. We propose and evaluate a compact CNN architecture on a dataset consisting of diverse textured surfaces with variously-shaped weakly-labeled anomalies. The proposed approach achieves state-of-the-art results in terms of anomaly segmentation as well as classification.
Understanding consumer interest in product and process‐based attributes for fresh produce

The choices consumers make about fresh produce, such as where it is purchased and what they are willing to pay, are likely influenced by a range of private and public attributes. This study uses factor and cluster analysis techniques to explore the preferences of consumers who responded to a 2006 national survey to determine the dimensions over which consumers make purchasing decisions and to identify key market segments. Analysis is based on a variety of survey questions relating to preferences for various fresh produce traits and process attributes, as well as willingness to pay for a subset of these attributes. We find that although there is only a small degree of correlation between tested variables, four consumer clusters can be identified as market segments: Urban, Assurance Seekers, Price Conscious Consumers, Quality and Safety Consumers, and Personal Value Buyers. Each cluster values both private and public attributes, though with differing intensities and focus. lEconLit citations: Q130, D120r. © 2008 Wiley Periodicals, Inc.
Urban rapid rail transit and gentrification in Canadian urban centres: A survival analysis approach

Despite the existing knowledge that urban rapid rail transit has many effects on surrounding areas, and despite some attempts to understand the links between transit and gentrification, there remain methodological gaps in the research. This study addresses the relationship between the implementation of urban rapid rail transit and gentrification, which is conceived of as an event. As such, an event analysis approach using ‘survival analysis’ is adopted as the statistical analytical tool. It tests whether proximity to rail transit is related to the onset of gentrification in census tracts in Canada’s largest cities. It is found that proximity to rail transit, and to other gentrifying census tracts, have a statistically significant effect on gentrification in two of the three cities analysed. By providing a methodological framework for the empirical analysis of the impact of urban rail transit on gentrification, this paper is a reference for both researchers and transportation planners.
Multi-level toxicity assessment of engineered cellulose nanofibrils in Daphnia magna

Abstract Cellulose nanofibril (CNF)-based materials are increasingly used in industrial and commercial applications. However, the impacts of CNF on aquatic life are poorly understood, and there are concerns regarding their potential toxicity. Using a combination of standard ecotoxicological tests and feeding experiments, we assessed the effects of CNF exposure (0.206–20.6 mg/L) on the feeding (food uptake and gut residence time) and life-history traits (growth and reproduction) in the cladoceran Daphnia magna. No mortality was observed in a 48 h acute exposure at 2060 mg/L. Moreover, a 21-day exposure at low food and moderate CNF levels induced a stimulatory effect on growth, likely driven by increased filtration efficiency, and, possibly, partial assimilation of the CNF by the animals. However, at low food levels and the highest CNF concentrations, growth and reproduction were negatively affected. These responses were linked to caloric restriction caused by dilution of the food source, but not an obstruction of the alimentary canal. Finally, no apparent translocation of CNF past the alimentary canal was detected. We conclude that CNF displays a low toxic potential to filter-feeding organisms and the expected environmental risks are low.
Consuming nostalgia? The appreciation of authenticity in local food production

Many consumers consider local food a more sustainable choice than conventional food because of the shorter transport distances involved as well as the support provided to local economies. In addition, consumers value the perceived safety benefits, ethical associations and improved taste of local food. In this study, we focus on the cultural meanings of locally produced food among Finnish consumers. Based on interviews with 22 consumers, our analysis suggests that, besides consumers valuing sustainable, healthy and tasty locally produced food, they perceived self-produced, self-processed items, including those they have gathered, hunted and fished themselves, as the most authentic local food. Furthermore, local food is associated with craftsmanship and artisan production. We also found that interviewees tended to historicize their relationship to food through local production. Thus, consumers seem to be in search of ‘real’ or ‘true’ food that is embedded in their personal and shared social histories.
The NAIRU, Aggregate Demand and Investment

The nature of the non-accelerating inflation rate of unemployment (NAIRU) is analysed. The focus of our analysis is the role of aggregate demand and capacity in the context of the NAIRU. Two aspects of the relationship between the level of aggregate demand and the NAIRU are of particular significance. First, it is argued that the real wage-employment relationship based on enterprise decisions cannot be fully articulated without reference to the level of aggregate demand. Second, a model which allows for variable returns to labour and the notion of full capacity is used to explore the effects of shifts in the capital stock on the real wage-employment relationship. The model is specifically used to explore whether a sufficiently expansionary environment can generate sufficient investment to shift that relationship until the NAIRU is compatible with full employment. A number of limitations on the conclusions reached are considered, and the policy implications are briefly considered.
Uveal melanoma: Finland v India

We have read with great interest the article by Eskelin and Kivela.1 This study provides information as to how uveal melanoma can be diagnosed and treated early if fundus examination is done by an ophthalmologist and also emphasises that routine indirect ophthalmoscopy should be done even in asymptomatic patients having an ophthalmic check up. We feel that indirect ophthalmoscopic evaluation of the dilated fundus is essential for …
A Proteolytic NH2-terminal Truncation of Cardiac Troponin I That Is Up-regulated in Simulated Microgravity*

In a tail suspension rat model, we investigated changes in myofilament protein during cardiac adaptation in simulated microgravity. Contractile force and velocity of cardiac muscle were decreased in the tail suspension rats as compared with the control. Ca2+-dependent actomyosin ATPase activity was also decreased; however, sensitivity of cardiac muscle to Ca2+ activation was unchanged. There was no change in expression of myosin heavy chain, tropomyosin, troponin T, or troponin I isoforms in hearts of tail suspension rats. A novel finding is a fragment of cardiac troponin I (cTnI) that had increased amounts in the heart of tail suspension rats. Binding of this cTnI fragment by a monoclonal antibody that specifically recognizes the COOH terminus indicates an intact COOH terminus. NH2-terminal sequence analysis of the cTnI fragment revealed truncations primarily of amino acids 1–26 and 1–27 and smaller amounts of 1–30, including Ser23 and Ser24, which are substrates of protein kinase A phosphorylation. This cTnI fragment is present in normal cardiac muscle and incorporated into myofibrils, indicating a role in regulating contractility. This proteolytic modification of cTnI up-regulated during simulated microgravity suggests a potential role of the NH2-terminal segment of cTnI in functional adaptations of cardiac muscle.
Plurality Rule, Proportional Representation, and the German Bundestag: How Incentives to Pork-Barrel Differ Across Electoral Systems

This paper examines the importance of electoral rules for legislators’ behavior. The German electoral system includes a mechanism which assigns whether legislators are elected under the “first-past-the-post” (FPTP), or the proportional representation (PR) electoral rule. Using this institution, we identify the effect of electoral rules on legislators’ behavior and disentangle whether so-called pork barrel politics are due to political climate in a country or due to the electoral rule employed. We find significant differences in committee membership, depending whether the legislator is elected though FPTP or PR. legislators elected through FPTP system are members of committees that allows them to service their geographically based constituency. Legislators elected through PR are members of committees that service the party constituencies, which are not necessarily geographically based.
Infraclavicular Brachial Plexus Block Versus Humeral Approach: Comparison of Anesthetic Time and Efficacy

Most upper arm regional anesthesia techniques are successful and differences in efficacy should not dictate the choice of technique. In the present study, we compared humeral block (HB) and infraclavicular brachial plexus block (ICB) using anesthetic time (i.e., duration of the procedure + onset time) as the primary outcome measure. The block was successful when a complete sensory block was obtained in the four major nerves of the arm, and the time to complete block was recorded. Patients undergoing orthopedic surgery of the upper limb were included in a prospective randomized study and received ICB (group I, n = 60 patients) or HB (group H, n = 60 patients). Total anesthetic time was 19.5 min (95% confidence interval [CI], 17.4—21.6 min) for ICB and 20.8 min (95% CI, 18.7--22.9 min) for HB (not significant). Time to perform the block was 4.5 min (95% CI, 4-5 min) for ICB and 9.8 min (95% CI, 8.9--10.7 min) for HB (P < 0.05). The onset time was 15 min (95% CI, 13-17 min) for ICB and 11 min (95% CI, 9--13 min) for HB (P < 0.05). The success rate was 92% for ICB and 95% for HB (not significant). One self-limited vascular puncture was made in each group. HB had a faster onset time but ICB using a double-stimulation technique was faster to perform. Anesthetic time was similar with the two techniques.
Do Unions Increase Labor Shares? Evidence from US Industry-Level Data

We explore the relationship between union membership rates and labor shares using panel data on 35 industries, spanning the entire US economy, for the years 1983–2005. For the full sample, a standard deviation increase in union membership rates is associated with an increase in an industry’s labor share of about 10%. Starting from the mean labor share in our sample (0.614), this effect amounts to about 6 percentage points. However, the effect is weaker and not statistically significant for manufacturing industries. We control for the capital-to-output ratio in all of our estimations, and the results are consistent with an elasticity of substitution between capital and labor that is less than unity. As such, the positive union effect on labor share is consistent with either the right-to-manage or the efficiency bargaining model of unions.
Rural Reforms and Agricultural Growth in China.

This paper employs province-level panel data to assess the contributions of decollectivization, price adjustments, and other reforms to China's agricultural growth in the reform period. Decollectivization is found to improve total factor productivity and to account for about half of the output growth during 1978-84. The adjustment in state procurement prices also contributed positively to output growth. Its impact came mainly from the responses in input use. The effect of other market-related reforms on productivity and output growth was very small. Reasons for slowdown in agricultural growth after 1984 are also analyzed.
