Developing Country Superwomen: Impacts of Trade Liberalisation on Female Market and Domestic Work

This study analyses the effects of trade liberalisation on male and female work in Nepal. Our contribution is principally based upon the leisure activities modeling on one hand, and the effects of male participation in domestic work with trade policy analysis on the other hand. While previous studies explicitly incorporate leisure activities that required data about which little is known, we use a microeconomic model and alternative calibration procedures to avoid arbitrariness. The experiment conducted in this study shows that the complete elimination of tariffs on imported goods in Nepal benefits women more than men in terms of earnings as their wage increases relatively to men. Generally, female market work expands in rural households and contracts in urban households. It appears that the entrance into market production has not been met with an equivalent reduction in the time they spend in domestic work. Consequently the leisure time of women declines as they enter the labor market. Furthermore, the study indicates that leisure time consumed by men, which is already greater than that consumed by women, increases with trade reform. The extend of male participation in domestic work significantly conditions the impacts on male and female wage rates and household labor supply decisions. When male participation in domestic work activities is low, women generally devote less time to market labor. However, their contribution to household income strill increases following trade reform as their wage rates rise relative to male market wage rates. Women are more responsive to the market when there is greatest scope to substitute between female domestic and market work, as occurs when men are more involved in domestic work. However, even in these cases their domestic work does not necessarily decrease in the same proportion.
C-Myc regulation by costimulatory signals modulates the generation of CD8+ memory T cells during viral infection

The signalling mechanisms of costimulation in the development of memory T cells remain to be clarified. Here, we show that the transcription factor c-Myc in CD8+ T cells is controlled by costimulatory molecules, which modulates the development of memory CD8+ T cells. C-Myc expression was dramatically reduced in Cd28−/− or Ox40−/− memory CD8+ T cells, and c-Myc over-expression substantially reversed the defects in the development of T-cell memory following viral infection. C-Myc regulated the expression of survivin, an inhibitor of apoptosis, which promoted the generation of virus-specific memory CD8+ T cells. Moreover, over-expression of survivin with bcl-xL, a downstream molecule of NF-κB and intracellular target of costimulation that controls survival, in Cd28−/− or Ox40−/− CD8+ T cells, reversed the defects in the generation of memory T cells in response to viral infection. These results identify c-Myc as a key controller of memory CD8+ T cells from costimulatory signals.
Sociocultural and Demographic Risk Factors for the Development of Multiple Sclerosis in Kuwait: A Case - Control Study

Introduction Immunological, genetic and environmental factors are believed to play important roles in the pathogenesis of Multiple Sclerosis (MS). There have been many studies on risk factors for MS but these have been mainly in Caucasian populations; robust studies in Arab populations remain relatively uncommon. This study therefore aimed to identify behavioral, socio-cultural, and demographic factors associated with development of MS in Kuwait, a high income Arab country, currently undergoing a demographic transition. Subjects and methods In this case- control study, 195 Kuwaiti MS patients and 146 healthy age and sex-matched controls were recruited. Both groups of subjects were interviewed using a structured questionnaire, in relation to anthropometric, socio-cultural and demographic data, residence during the 1990/91 Gulf War and current and past medical history, including medications. We also clinically evaluated, and retrospectively reviewed medical records of patients to derive appropriate clinical information, including associated chronic medical illness requiring long-term treatment. Results On multiple logistic regression analysis after adjustment for potential confounders including age, gender and BMI, in all the subjects, a positive associations prevail with presence of MS and some sociocultural and demographic factors, which included non-Bedouin ethnicity (AOR 2, 95% CI 1.0-3.9, p 0.049), positive family history of MS (AOR 10.6, 95% CI 3.0-36.9), p < 0.001), and low daily sunlight exposure of < 15min/day (AOR 5.3, 95% CI 2.7-10.5 p < 0.001). In addition, while 41.8% of MS patients indicated at least one comorbidity, only 26.8% of the controls reported any associated physical illness, with the suggestion that presence of certain comorbidities might increase MS risk (AOR 2.4, 95% CI 1.3-4.7, p < 0.001). Other risk variables such as smoking status and mode of routine outdoor dressing were not significant in all the MS subjects taken as a whole, but demonstrated variably positive associations in the MS subgroup classified as those with established disease and those who were newly diagnosed and drug naïve. Conclusions This study suggests that a positive family history of MS and presence of certain comorbidities appeared to be associated with an increased risk of developing MS. In contrast, relatively increased amount of daily sunlight exposure and Bedouin ethnicity appear to somewhat be protective. It is speculated that the relationship of sunlight exposure with MS might be due to vitamin D availability, and is deserving of further study.
Out of Africa: Biogeography and diversification of the pantropical pond skater genus Limnogonus Stål, 1868 (Hemiptera: Gerridae)

Abstract Gondwanan vicariance, long‐distance dispersal (LDD), and boreotropical migration have been proposed as alternative hypotheses explaining the pantropical distribution pattern of organisms. In this study, the historical biogeography of the pond skater genus Limnogonus was reconstructed to evaluate the impact of biogeographical scenarios in shaping their modern transoceanic disjunction. We sampled almost 65% of recognized Limnogonus species. Four DNA fragments including 69 sequences were used to reconstruct a phylogram. Divergence time was estimated using a Bayesian relaxed clock method and three fossil calibrations. Diversification dynamics and ancestral area reconstruction were investigated by using maximum likelihood and Bayesian approaches. Our results showed the crown group of Limnogonus originated and diversified in Africa in the early Eocene (49 Ma, HPD: 38–60 Ma), subsequently expanding into other regions via dispersal. The colonization of the New World originated from the Oriental Region probably via the Bering Land Bridge in the late Eocene. Two split events between the Old World and New World were identified: one between Neotropics and Oriental region around the middle Oligocene (30 Ma, HPD: 22–38 Ma), and the other between Neotropics and Africa during the middle Miocene (14 Ma, HPD: 8–21 Ma). The evolutionary history of Limnogonus involved two biogeographical processes. Gondwanan vicariance was not supported in our analyses. The diversification of Limnogonus among Africa, Oriental, and Neotropical regions corresponded with the age of land bridge connection and dispersed as a member associated with the broad boreotropical belt before local cooling (34 Ma). The current transoceanic disjunctions in Limnogonus could be better explained by the disruption of “mixed‐mesophytic” forest belt; however, the direct transoceanic LDD between the Neotropics and Africa could not be ruled out. In addition, the “LDD” model coupled with island hopping could be a reasonable explanation for the diversification of the Oriental and Australian regions during the Oligocene.
Effects of sport participation on adolescent self-esteem and body-image: differences in gender and types of sports explored

Sport participation has been shown to positively influence self-esteem and body-image of adolescent youth. This effect was measured in a sample of Icelandic participants, with the effects of gender and participation in individual and team sports explored. The study used previously gathered data “Ungt Fólk á Íslandi 2010” (Youth in Iceland) collected by The Icelandic Centre for Social Research in the fall of 2010. The study was implemented on a sample of 1994 participants from the previously gathered data. The Rosenberg scale of self-esteem was used to measure participants’ selfesteem and the Offer scale of body-image to measure participants’ body-image. Participants ́ weekly sport participation and type of sports they practiced, individual or team-sports, were also measured. The results show that participants who practice sports on a weekly basis have significantly higher self-esteem and body-image than participants who do not. Participants who practice individual sports have significantly higher self-esteem than participants in team-sports. Male participants had significantly higher body-image than female participants.
Farmer participation in supermarket channels and technical efficiency: The case of vegetable production in Kenya

Supermarkets and high-value exports are currently gaining ground in the agri-food systems of many developing countries. While recent research has analyzed income effects in the small farm sector, impacts on farming efficiency have hardly been studied. Using a survey of Kenyan vegetable growers and a stochastic frontier approach, we show that participation in supermarket channels increases mean technical efficiency by 19%. This gain is bigger at lower levels of efficiency, suggesting the potential for positive income distribution effects. However, disadvantaged farms often have problems in meeting strict supermarket requirements. Innovative market linkage initiatives can increase the probability of participation significantly.
Velocity and the Variability of Money Growth: Evidence from Granger-Causality Tests Reevaluated

Hall and Nobel (1987) use the Granger-causality test to show that volatility influences velocity, leading them to conclude that the recent decline in the velocity of Ml is due to increased volatility of money growth which is alleged to be caused by the Federal Reserve's new operating procedures. This note shows that such a conclusion is unwarranted, because the causality result reported in their paper is not robust. When the test is implemented either using first differences of the volatility variable or using the volatility and velocity variables that are based on the broad definition of money or over the sample period that includes the 1985-86 episode of the decline in the velocity of Ml, then the test results do not support the inference that volatility influences velocity.
Monitoring Macroeconomic Imbalances: Is EU Surveillance More Effective than IMF Surveillance?

The paper examines the macroeconomic imbalance procedure (MIP) with the purpose of assessing its potential effectiveness compared to International Monetary Fund (IMF) surveillance. The comparison reveals that the MIP performs better than the Fund's surveillance in terms of the provision of clear and practical advice, knowledge of domestic polities and ease of activating sanctions. Neither the MIP nor the IMF, however, provide for mechanisms to prevent political considerations from interfering with the activation of sanctions and the distribution of the burden of adjustment. The MIP also does not attenuate problems of asymmetric treatment that create the conditions for public backlashes. Its single-country focus and the limited integration of macroeconomic and financial analysis are further factors that may undermine the effectiveness of the MIP. In the conclusions, the paper reflects on the factors that may help explain the limited incorporation of the lessons available from the Fund's experience into the MIP.
Inverter VAR control for distribution systems with renewables

Motivated by the need to cope with rapid and random fluctuations of renewable generation, we presents a model that augments the traditional Volt/VAR control through switched controllers on a slow timescale with inverter control on a fast timescale. The optimization problem is generally nonconvex and therefore hard to solve. We propose a simple convex relaxation and prove that it is exact provided over-satisfaction of load is allowed. Hence Volt/VAR control over radial networks is efficiently solvable. Simulations of a real-world distribution circuit illustrates that the proposed inverter control achieves significant improvement over the IEEE 1547 standard in terms of power quality and power savings.
Selective RNAVersus DNA G-Quadruplex Targeting by In Situ Click Chemistry

It all clicks into place: A potent telomere-targeting small molecule has been identified by using the copper-free 1,3-dipolar cycloaddition of a series of alkyne and azide building blocks catalyzed by a non-Watson-Crick DNA secondary structure (see picture). This method rapidly identifies, otherwise unanticipated, potent small-molecule probes to selectively target a given RNA or DNA.
Looking Inward for Transformative Growth in China

Export led growth has been very effective in modernising China’s economy and establishing a large high-saving middle class. Notwithstanding political opposition from trading partners, this growth strategy has also offered the rest of the world improved terms of trade in both product and financial markets, in the form of cheaper light manufactures and cheaper credit. Yet slowing demand in export destinations has forced a transition to inward-sourced growth. This paper uses a numerical model of the Chinese economy with oligopoly behaviour to examine the available “inward” sources of transformative growth along with the policies needed to exploit them. The potential for considerable further “transformative” growth is shown to be considerable though it will require accelerated skilled labour supply growth and the politically difficult extension of industry policy reform to heavy manufacturing and services.
Non-Tariff Measures Faced by Philippine Agricultural Exports in East Asia

Many consider non-tariff measures (NTMs) as another protectionist stratagem to prevent exports, especially of agriculture, from developing countries. Philippine exporters seem to be taking things in stride, however. The estimated cost of less than 3% of sales borne by a Philippine food exporter due to compliance with certification requirements is less than three percent of sales—relatively insignificant. However, the increased cost from NTMs can adversely affect small-scale industries and exporters that sell products to low-margin foreign markets. The paper also traces the Philippine export products affected by non-tariff measures imposed by East Asian markets. In all, the NTMs of Japan, Korea, and China affect a total of US million of Philippine agriculture exports to these markets, or 2% to 22% of Philippine agricultural exports in these three countries.
The Accrual Effect on Future Earnings

Earnings manipulation has become a widespread practice for US corporations. However, most studies in the literature focus on whether certain incentives would facilitate managers to manipulate earnings and there has been little evidence documenting the consequences of earnings manipulation. This paper fills this gap by examining how current accruals affect future earnings (the accrual effect) and measuring the size of this effect. We find that the aggregate future earnings will decrease by $0.046 and $0.096, respectively, in the next one and three years for a $1 increase of current accruals. Over the very long-term (25 years), 20% of current accruals will reverse. This negative accrual effect is more significant for firms with high price-earnings ratios, high market-to-book ratios and high accruals where earnings management is more likely to occur. We show that incorporating the accrual effect is useful in improving the accuracy of earnings forecasts for these firms. Accordingly, the empirical results are consistent with the notion that earnings management causes the negative relationship between current accruals and future earnings. In addition, this paper shows that one recently developed accrual model has better performance than the popularly cited model in identifying manipulated earnings.
A hybrid equivalent capacity admission control algorithm for ATM congestion control

Admission control is an important method for congestion control in ATM networks. The authors propose an efficient hybrid algorithm for the calculation of the required equivalent bandwidth of a virtual circuit call given a traffic descriptor consisting of its class, average bit rate, peak bit rate and mean burst length. The algorithm is a hybrid of the class related rule and planar approximation methods thus accommodating homogeneous traffic as well as heterogeneous quality of service requirements traffic. The algorithm employs a limited statistical multiplexing method for improved network bandwidth exploitation. The combination of efficient operation for homogeneous virtual channels and a high statistical multiplexing gain for heterogeneous calls results in a more effective admission control strategy than either method alone. <<ETX>>
Emotion recognition method using entropy analysis of EEG signals

This paper proposes an emotion recognition system using EEG signals, therefore a new approach to emotion state analysis by approximate (ApEn) and wavelet entropy (WE) is described. We have used EEG signals recorded during emotion in five channels (FP1, FP2, T3, T4 and Pz), under pictures induction environment (calm- neutral and negative excited) for participants. After a brief introduction to the concept, the ApEn and WE were extracted from two different EEG time series. The result showed that, the classification accuracy in two emotion states was 73.25% using the support vector machine (SVM) classifier. The simulations showed that the classification accuracy is good and the proposed methods are effective. During an emotion, the EEG is less complex compared to the normal, indicating reduction in active neuronal process in the brain.
A Dynamic Programming Model of Retirement Behavior

This paper formulates a model of retirement behavior based on the solution to a stochastic dynamic programming problem. The workers objective is to maximize expected discounted utility over his remaining lifetime. At each time period the worker chooses how much to consume and whether to work full-time, part-time, or exit the labor force. The model accounts for the sequential nature f the retirement decision problem, and the role of expectations of uncertain future variables such as the worker's future lifespan, health status, marital and family status, employment status, as well as earnings from employment, assets, and social security retirement, disability and medicare payments. This paper applies a "nested fixed point" algorithm that converts the dynamic programming problem into the problem of repeatedly recomputing the fixed point to a contraction mapping operator as a subroutine of a standard nonlinear maximum likelihood program. The goal of the paper is to demonstrate that a fairly complex and realistic formulation of the retirement problem can be estimated using this algorithm and a current generation supercomputer, the Cray-2.
Body fat measurement among Singaporean Chinese, Malays and Indians: a comparative study using a four-compartment model and different two-compartment models

This cross-sectional study compared body fat percentage (BF%) obtained from a four-compartment (4C) model with BF% from hydrometry (using 2H2O), dual-energy X-ray absorptiometry (DXA) and densitometry among the three main ethnic groups (Chinese, Malays and Indians) in Singapore, and determined the suitability of two-compartment (2C) models as surrogate methods for assessing BF% among different ethnic groups. A total of 291 subjects (108 Chinese, seventy-six Malays, 107 Indians) were selected to ensure an adequate representation of age range (18–75 years) and BMI range (16–40 kg/m2) of the general adult population, with almost equal numbers from each gender group. Body weight was measured, together with body height, total body water by 2H2O dilution, densitometry with Bodpod® and bone mineral content with Hologic® QDR-4500. BF% measurements with a 4C model for the subgroups were: Chinese females 33.5 (SD 7.5), CHINESE MALES 24.4 (sd 6.1), Malay females 37.8 (sd 6.3), Malay males 26.0 (sd 7.6), Indian females 38.2 (sd 7.0), Indian males 28.1 (sd 5.5). Differences between BF% measured by the 4C and 2C models (hydrometry, DXA and densitometry) were found, with underestimation of BF% in all the ethnic-gender groups by DXA of 2.1–4.2 BF% and by densitometry of 0.5–3.2 BF%). On a group level, the differences in BF% between the 4C model and 2H2O were the lowest (0.0–1.4 BF% in the different groups), while differences between the 4C model and DXA were the highest. Differences between the 4C model and 2H2O and between the 4C model and DXA were positively correlated with the 4C model, water fraction (fwater) of fat-free mass (FFM) and the mineral fraction (fmineral) of FFM, and negatively correlated with density of the FFM (DFFM), while the difference between 4C model and densitometry correlated with these variables negatively and positively respectively (i.e. the correlations were opposite). The largest contributors to the observed differences were fwater and DFFM. When validated against the reference 4C model, 2C models were found to be unsuitable for accurate measurements of BF% at the individual level, owing to the high errors and violation of assumptions of constant hydration of FFM and DFFM among the ethnic groups. On a group level, the best 2C model for measuring BF% among Singaporeans was found to be 2H2O.
A review of patient and carer participation and the use of qualitative research in the development of core outcome sets

Background To be meaningful, a core outcome set (COS) should be relevant to all stakeholders including patients and carers. This review aimed to explore the methods by which patients and carers have been included as participants in COS development exercises and, in particular, the use and reporting of qualitative methods. Methods In August 2015, a search of the Core Outcomes Measures in Effectiveness Trials (COMET) database was undertaken to identify papers involving patients and carers in COS development. Data were extracted to identify the data collection methods used in COS development, the number of health professionals, patients and carers participating in these, and the reported details of qualitative research undertaken. Results Fifty-nine papers reporting patient and carer participation were included in the review, ten of which reported using qualitative methods. Although patients and carers participated in outcome elicitation for inclusion in COS processes, health professionals tended to dominate the prioritisation exercises. Of the ten qualitative papers, only three were reported as a clear pre-designed part of a COS process. Qualitative data were collected using interviews, focus groups or a combination of these. None of the qualitative papers reported an underpinning methodological framework and details regarding data saturation, reflexivity and resource use associated with data collection were often poorly reported. Five papers reported difficulty in achieving a diverse sample of participants and two reported that a large and varied range of outcomes were often identified by participants making subsequent rating and ranking difficult. Conclusions Consideration of the best way to include patients and carers throughout the COS development process is needed. Additionally, further work is required to assess the potential role of qualitative methods in COS, to explore the knowledge produced by different qualitative data collection methods, and to evaluate the time and resources required to incorporate qualitative methods into COS development.
