Can the Stochastic Equilibrium Job Search Models Fit Transition Economies

The aim of this study is to apply the stochastic job search framework to the analysis of three transition economies (Poland, Hungary, and the Czech Republic). Two versions of equilibrium unemployment models have been developed resembling Mortensen and Pissarides’ models, namely the dynamic and stochastic models. The dynamic model’s properties were briefly examined by evaluating the Jacobian matrix and plotting the phase plane of the economy. In the primary analysis of the stochastic model, job destruction decisions are endogenous as a response to random productivity changes. A martingale, i.e. a discrete-space version of the geometric Brownian motion with the drift and volatility parameter, was used to enable fluctuation of endogenous variables and to perform numerical simulations. The results are promising, although ambiguous in some points, e.g. the main model-generated time-series are close to the empirical time-series, including reasonable fluctuations, correlation signs, and autocorrelations. However, the model was unable to capture some subtle differences in productivity and job destruction rate series across the countries, which is its main limitation.
Positive Effect of Nitric Oxide on Morphine-Induced Place Conditioning inWistar Rats Treated by Colchicine Intra-Hippocampal CA1

Colchicine is a potent alkaloid neurotoxin known as a selective neurotoxin of granular cells of hippocampal formation. This research aimed to assess the consequences of hippocampal reward circuitry damaged by colchicine. Male Wistar rats were examined for saline conditioning a week after receiving of colchicine (1-8μg/rat, intra-CA1). Control group was simply microinjected saline (1μl/rat, intra-CA1). In addition, two categories of animals pre-treated by colchicine (2,8μg/rat, intra-CA1) were evaluated for place preference induced of morphine (2.5-7.5 mg/kg, s.c.) using a three-day schedule of unbiased paradigm. Also sham operated legend “normal” group passed the conditioning by morphine. This group was pre-treated saline (1μl/rat, intra-CA1) instead of colchicine. According to the results, the injection of colchicine (1-8μg/rat, intra-CA1) induced a place aversion in saline conditioning at the higher doses (8μg/rat). Furthermore, the colchicine treated rats showed histologically a significant ( p<0.001 ) decrease in numbers of pyramidal cells of CA1. On the other hand, morphine induced a significant place preference in animals pre-treated by colchicine (2,8μg/rat, intra-CA1). Moreover, pre-microinjection of L-arginine (0.3- 3μg/rat, intra-CA1), a precursor of nitric oxide (NO), pre-testing of morphine response caused a positive effect on expression of response to morphine. However, this effect was reversed when L-NAME (0.3-3μg/rat, intra-CA1) was injected into the CA1 prior to the administration of L-arginine (3μg/rat, intra-CA1). Based on data the neurotoxin, colchicine, may affect the place conditioning reward circuitry via decreasing of pyramidal cells in the CA1 area ( p<0.01 ), an effect which most likely can be improved by morphine administration peripherally. In conclusion the molecule NO into CA1 may have a positive force on morphine-induced place conditioning in Wistar rats received colchicine intra-CA1.
THE EFFICIENCY OF PROTEIN UTILIZATION IN DIFFERENT BROILER STRAINS

The objective of this work was to study the protein utilization and protein turnover of different broiler strains and was carried out in completely randomized design. One hundred and forty four sexed doc from each strain (Cobb =A, Ingham = B and Steggels = C) were divided into a factorial arrangement (three dietary protein, two sexes and three strains). Two regimens of composite mixes of a summit and dilution diet and a free choice between these two diets. Diets were changed weekly, with notional crude protein levels at one day-old of 240g/kg for all chickens, and at 42 days of age of 120 or 180 g/kg in the low and high protein. Protein utilization efficiency (PRE) was measured from 39-42 d of age. PRE increased with the increasing of dietary protein in strains A and C and had much higher response than in strain B. The moisture: protein ratios were 2.51, 2.65 and 2.58 in strains A, B and C, indicating strain B contained higher moisture and body fat and less protein. Involvement of genetic controls as the selection effect seems to increase the capacity of chickens in improving nutrient utilization.
CUR Based Initialization Strategy for Non-Negative Matrix Factorization in Application to Hyperspectral Unmixing

Hyperspectral unmixing is a powerful tool for the remote sensing image mining. Nonnegative matrix factorization (NMF) has been adopted to deal with this issue, while the precision of unmixing is closely related with the local minimizers of NMF. We present two novel initialization strategies that is based on CUR decomposition, which is physically meaningful. In the experimental test, NMF with the new initialization method is used to unmix the urban scene which was captured by airborne visible/infrared imaging spectrometer (AVIRIS) in 1997, numerical results show that the initialization methods work well.
Many Children Left Behind? Textbooks and Test Scores in Kenya

A randomized evaluation suggests that a program which provided official textbooks to randomly selected rural Kenyan primary schools did not increase test scores for the average student. In contrast, the previous literature suggests that textbook provision has a large impact on test scores. Disaggregating the results by students? initial academic achievement suggests a potential explanation for the lack of an overall impact. Textbooks increased scores for students with high initial academic achievement and increased the probability that the students who had made it to the selective final year of primary school would go on to secondary school. However, students with weaker academic backgrounds did not benefit from the textbooks. Many pupils could not read the textbooks, which are written in English, most students? third language. The results are consistent with the hypothesis that the Kenyan education system and curricular materials are oriented to the academically strongest students rather than to typical students. More generally, many students may be left behind in societies that combine 1) a centralized, unified education system; 2) the heterogeneity in student preparation associated with rapid expansion of education; and 3) disproportionate elite power.
Circuit and multipolar approaches to investigate the balance of powers in 2D scat-tering problems

Circuit and multipolar approaches are presented to investigate the correlation between absorption and scattering processes in 2D problems. This investigation was inspired by earlier works of R. E. Collin, which pointed out deflciencies of the Thevenin/Norton circuit models to evaluate the scattered and absorbed powers associated with receiving antennas and, thus, encouraged research on new analytical tools to address these problems. Power balance results are obtained with both circuit and multipolar approaches that are fully consistent. This analysis serves to illustrate how the correlation between absorption and scattering processes results in upper bounds for their power magnitudes, as well as stringent design trade-ofis in both far-fleld and near-fleld source and scattering technologies.
Optimization of Data Density and Energy inWireless Sensor Network

Wireless sensor networks consist of sensor nodes with sensing and communication capabilities. We focus on data aggregation problems in energy constrained sensor networks. The main goal of data aggregation algorithms is to gather and aggregate data in an energy efficient manner so that network lifetime is enhanced. In this paper, we present a survey of data aggregation algorithms in wireless sensor networks. We compare and contrast different algorithms on the basis of performance measures such as lifetime, latency and data accuracy. We conclude with possible future research directions. Since sensors have limited lifetime, the need for developing algorithms for aggregating sensors' data forms an important concern in the area of WSNs. We present W-LEACH, a data-stream aggregation algorithm for WSNs that extends LEACH algorithm. W-LEACH is able to handle non-uniform networks as well as uniform networks, while not affecting the network lifetime. It, instead, increases the average lifetime for sensors. We simulate our algorithm to evaluate its performance. Results show that WLEACH increases the network lifetime and the average lifetime for sensors for uniform and non-uniform WSNs.
of Hypertension and Management

Background: Elderly stroke outpatients, without aphasia, hemiplegia, or spatial neglect in their post-acute phase, are typically monitored on a quarterly, or fewer, physician-visit schedule. Thus, the patient’s status goes unreported between visits unless a remarkable untoward event occurs. Methods: We devised an electronic diary (e-diary) to serve as an adjunct to physician visit-to-visit management of BP in elderly stroke patients. In phase 1 implementation, the e-diary was used by eight adults up to three times per day to monitor BP (via Bluetooth), to report biopsychological factors, and then to coach BP self-management. In phase 2, the e-diary supported BP self-management. Results: E-diary monitoring provided earlier detection of four, otherwise undetected, spikes in SBP and HR that generated prompter referrals in three patients. E-diary-mediated coaching of improved health practices produced BP self-management gains: 5/6 patients showed statistically significant reductions in BP. The statistically significant reductions in SBP were into the 120-129 mm Hg range in three and were below 120 in a fourth. In a sixth patient, self-management reduced the number of SBP spikes (i.e., SBP ≥ 130). The data of a seventh patient revealed that their frequent, undiagnosed episodes of altered consciousness - i.e., feeling “not-with-it” - were correlated with variations in their lower, but broad-ranged SBP. Conclusion: Our findings illustrate the efficacy of our e-diary-based adjunct for elderly stroke patient BP self-management and for facilitating differential diagnosis involving SBP. They also suggest the feasibility of using a customized diary remotely, for chronic diseases more broadly in an aging population.
Effect of transcutaneous electromyostimulation on pressure pain threshold and tolerance in athletes under eccentric exercise

Exercise-induced hypoalgesia typically reported during and / or following exercise. In this study, we investigated the role of transcutaneous electromyostimulation (EMS) on pressure pain threshold and tolerance in athletes under eccentric exercise. Eleven male athletes aged 23,125 ± 0,99 years with 10,25 ± 2,66 years of athletic training were recruited for this study. Following baseline measurements of pressure pain threshold and tolerance from m. biceps brachii and m. triceps brachii muscle and myofascial regions of the dominant upper extremity by using a digital algometer, subjects were underwent an acute bout of eccentric exercise. Participants were completed 4 sets of eccentric exercise each comprising 20 repetitions of lifting 80% of their 1 RM by using a dumbbell. Pressure pain threshold and tolerance tests were repeated 10, 20 and 30 minutes, and 24 and 48 hours following exercise. One week after acute exercise protocol, EMS protocol was applied to the participants immediately following eccentric exercise, and all measurements were repeated at the same timeline as eccentric exercise. Standard EMS protocol at active recovery mode for 10 minutes was applied to the m. biceps brachii muscle by using surface electrodes. Results are presented as mean + standarts deviation. Data of the same timeline were analyzed by using repeated measures of ANOVA followed by Tukey’s post hoc test. A level of p<0.05 was accepted statistical significant. Eccentric exercise resulted to increase the pain tolerence in athletes, and EMS was found to decrease the pain tolerence 10 and 20 minutes at the muscle region, and 10 and 30 minutes, and 24 hours at the myofascial region of m. biceps brachii, 10 min and 24 hr from muscle region, 10 and 30 min and 24 hr from myofascial region of M. triceps brachii following acute bout of eccentric exercise. We concluded that EMS at active recovery phase mitigates the the hypoalgesic response following single bout of eccentric exercise.
Gender Gaps Across the Earnings Distribution in Britain: Are Women Bossy Enough?

This paper investigates gender differences between the log wage distributions of full-time British employees in the public and private sectors. After allowing for positive selection into full-time employment by women, we find significant and substantial gender earnings gaps, and evidence of glass ceilings, in both sectors. The earnings gaps amongst the higher income earners are found to be related to there being a scarcity of senior women in high skilled, white-collar occupations, especially in the public sector.
Numerical simulation of a continental-scale Saharan dust event

[1] Using an integrated dust-storm modeling system, we simulate the severe Saharan dust episode between 1 and 10 March 2004. The simulations are compared with surface synoptic data and satellite images and are found to agree well with the observations. The synoptic systems that generated the dust storms and the evolution of the dust patterns are analyzed. It is revealed that a cyclogenesis over central Sahara, accompanied by an anticyclone over the Atlantic and a monsoon trough in the tropics, was responsible for the widespread continental-scale dust storms in North Africa. Dust first appeared in west Sahara, then in east Sahara and much of the dust emitted from east Sahara was transported to the monsoon trough, resulting in high concentrations of suspended dust over the Sahel (column dust load up to 10 g m−2). The main dust source regions were (1) Mauritania, (2) Chad and Niger, and (3) Libya, Egypt, and Sudan. The region between 10°N and 17°N was one of net dust deposition. We estimate that 715.8 megatons (Mt) of dust was emitted from North Africa during the episode, 608.2 Mt of which was deposited to the continent, and the net dust emission was 107.6 Mt. Of the 107.6 Mt, with respect to the model domain, 7.3 Mt was deposited to the ocean, 79.8 Mt was transported across the domain boundaries, and 20.5 Mt was suspended in the atmosphere.
An analysis of the impacts of consumer shopping characteristics and perceived website quality on purchase intention from a private sales site

The current study explored the impacts of shopping characteristics and perceived website quality on purchase intention from a private sales site. Data were collected from 164 female respondents who are members of at least one private sale website. Fashion leadership (two dimensions) bargain shopping, impulse buying, and hedonic motivations were the five shopping characteristics chosen, and it was found that impulse buying and bargain shopping were significant predictors of purchase intention. Of the three dimensions of website quality found, ease of use was the only dimension of website quality to be a significant predictor of purchase intention. Furthermore, the relationships between shopping characteristics, perceived website quality, and purchase intention were tested and partially supported.

Impact of Indian Cultural Values and Lifestyles on Meaning of Branded Products: Study on University Students in India

ABSTRACT In recent years, India has witnessed a transformation not only in economic standards but also in sociocultural factors. The traditional values, norms, and behaviors are being altered into more Westernized and global values. This is what meets the eyes of a typical observer. This research was directed toward ascertaining the transition of Indian society from a collectivist society to an individualist society with focus on individuals’ lifestyles and values. The purpose of the research was to understand the role of collectivist/individualist lifestyle variables on brand meanings by Indian university students. Correlation and multiple regression tests were administered to analyze the data. The findings suggest that Indian youths may appear to endorse Western values, but family traditions, group values, and national traditions play a pivotal role in determining brand meanings.
QML INFERENCE FOR VOLATILITY MODELS WITH COVARIATES

The asymptotic distribution of the Gaussian quasi-maximum likelihood estimator (QMLE) is obtained for a wide class of asymmetric GARCH models with exogenous covariates. The true value of the parameter is not restricted to belong to the interior of the parameter space, which allows us to derive tests for the significance of the parameters. In particular, the relevance of the exogenous variables can be assessed. The results are obtained without assuming that the innovations are independent, which allows conditioning on different information sets. Monte Carlo experiments and applications to financial series illustrate the asymptotic results. In particular, an empirical study demonstrates that the realized volatility can be a helpful covariate for predicting squared returns.
Facilitation cascade maintains a kelp community

There is increasing interest in how facilitation cascades — nested positive indirect inter- actions involving at least 3 species — maintain com- munity structure. Here we investigated whether the positive relationship between the kelp Ecklonia radiata and the gastropod Phasianotrochus eximius is mediated by a third species, the sea urchin Holopneustes purpurascens, via a facilitation cas- cade. Both the urchin and the gastropod are found enmeshed within the lamina of the common kelp E. radiata, which the urchin is known to consume. Sampling of urchin and gastropod abundances at 4 sites in Sydney, Australia, over 2 yr revealed that both H. purpurascens and P. eximius were more abundant on kelp than on other algal substrates and that the gastropod was more abundant on kelp with than without the urchin. Large P. eximius were found only on plants inhabited by H. pur- purascens, suggesting that either P. eximius is able to survive longer when it is part of this association or that adults actively move onto this substrate. When the presence/absence of H. purpurascens on kelp plants was manipulated experimentally in the field, greater recolonisation by P. eximius of kelp with than without urchins was observed. Urchins, by contrast, did not differentially respond to kelp with and without the gastropod, indicating that the association between the kelp and the urchin is maintained by a unidirectional facilitation cascade. Our study adds to growing evidence that facilita- tion cascades are a common mechanism by which community structure is maintained. Studies are now needed to assess their sensitivity to environmental change.

Household location and income: a spatial analysis for British cities

Using information on the exact location of urban households in Britain for the period 2009-2013 we explore the validity of standard urban land use models by estimating the extent to which distance of residence from the city centre is a function of income. This is the first study of its kind for British cities. After controlling for household characteristics and access to transport, as well as city and time effects, and taking account of both spatial and serial correlation, we find a strong positive association between household’s income and distance from the city centre. We also estimate the income elasticity of demand for land and find that this is not large enough to support the view that richer households locate further from the city centre mainly because they prefer larger dwellings. Finally, we find that while poorer households live closer to the city centre, they have experienced increasing real incomes over the period relative to those who live further away. This supports the view that cities in Britain attract poor people rather than generate poverty.
