Parental worklessness and children’s early school achievement and progress

In this paper we investigate the relationship between repeated parental worklessness and the academicprogress made by children in England in their first full year of primary school. We draw on data from two recent longitudinal birth cohort studies with multiple rounds of data collection in the very early years up to age 5. We use the Avon Longitudinal Study of Parents and Children (ALSPAC) which started collecting data from more than 14,000 children and their families in a geographically defined catchment area in 1991/2, and the Millennium Cohort Study (MCS), which is a sample of 19,000 children and their families born across the UK around the turn of this century. We constructed measures of repeated (persistent) and temporary (intermittent) worklessness and found that both were associated with lower levels of early academic achievement and progress of children. This association cannot be fully explained by a number of other socio-demographic risks factors (including parental education, income, housing conditions and health), indicating independent risk effects. We furthermore could identify beneficial effects of a stimulating early home-learning environment, which were significant even after controlling for previous levels of children’s cognitive and behavioural adjustment.
Evaluation of Interferon-Beta Protein Expression in HEK293T Cell-Line Transfected by Recombinant Construction, Pbud.Ifnβ-1a

Cytokines are a group of signaling glycoproteins that are expressed in respond to stimulus factors and antigens. IFNâ is an important cytokine that play role in immune processes, inflammation and host defense against external factors. In this study, the expression level of IFNβ protein in HEK293T cell line transfected by recombinant construction pBud. IFNβ examine via Dot blot and Elisa protein tests. Sequence of IFNβ gene with using of primers containing Kozak conserved sequence and enzyme restriction site of Kpnl and BglII amplified from pSVMdhfr vector. After treatment by above mentioned enzymes, IFNâ gene cloned in linearized pBud.CE4. 1. Structure of recombinant vector were examined via RFLP, Colony PCR and sequencing and finally transformed into competent Ecoli.TOP10 bacteria and next transfected to HEK293T cells. The results of protein tests indicate that recombinant IFNâ gene expressed successfully in HEK293T cell line under eEf1a promoter of selected vector. Proteins produced in prokaryotic systems are lacking glycosylation and thus have different physicochemical properties in comparison with normal protein production in the body. This causes side effects in the patient so the production of IFNâ protein in human HEK293T cells and high expression level of this protein is the benefits of this research.

A Profitability Analysis of Dairy Feeding Systems in the Northeast

This study analyzes the use and profitability of three distinct feeding systems; confinement feeding, traditional grazing, and management-intensive grazing from a randomly selected sample of northeastern dairy farms. The confinement feeding farms were significantly larger and produced more milk per cow, while the farms using management-intensive grazing incurred the lowest production costs. Both confinement feeding and management-intensive grazing generated significantly higher rates of return to farm assets relative to farms using a mixed system. Multiple regression analysis confirms the critical importance of herd size, milk production per cow, debt level and veterinary expenses to farm profitability in all production systems.
EFFECTS OF CLIMATE CHANGE ON LIVESTOCK PRODUCTION AND MITIGATION STRATEGIES - A REVIEW

Climate change is a long-term shift in the statistics of the weather such as temperature, radiation, wind and rainfall characteristics of a particular region. Climate change has profound effect on livestock. The anticipated rise in temperature due to climate change is likely to aggravate the heat stress in livestock, adversely affecting their productive and reproductive performance. The predicted negative impact of climate change on agriculture would also adversely affect livestock production by aggravating the feed and fodder shortages. The livestock sector which will be a sufferer of climate change is itself a large source of methane emissions, an important greenhouse gas. The paper mainly reviews the contribution of livestock to climate change and impacts of climate change on livestock milk production, reproduction, livestock diseases and mitigation strategies to counteract climate change effects.
Escalation Game with Endogenous Demands and The Nash Bargaining Solution

The paper examines the behavior of two agents who need to make a joint decision but they have conflicting preferences about the choice of the outcome. Conventionally such problem is considered as the bargaining problem described as the situation of dividing a pie. But we introduce the model that sheds a different light on the problem in question. The problem is described as the conflict situation modelled as a two-stage game. In the first stage players propose outcomes. The settlement is made if the proposed outcomes are the same. If not, the game moves onto the second stage where they play the concession game called the escalation game. In the escalation game, each player, in turn, has the choice between either to submit by accepting the other’s demand or to escalate by way of insisting his demand to be accepted. Each escalation generates a probability of an inefficient outcome. There are two main findings: (1) it is shown that the player’s decision is determined by his risk limit which measures his intensity towards winning. (2) if the escalation game allocates the demand of the player with the highest risk limit, then players propose the Nash cooperative solution.
Surgical Management of Liver Metastases from Colorectal Carcinoma

Abstract Colorectal carcinoma continues to be a leading cause in cancer-related mortality with more than 130,000 new cases diagnosed annually in the United States. About 50% of patients will develop colorectal cancer liver metastasis (CRLM). Liver resection continues to be the mainstay therapy in the management of CRLM and is associated with 25 to 60% 5-year survival. Alternative nonsurgical therapies offer modest survival when CRLM is unresectable. Herein, we provide an overview of key aspects of surgical approaches to the treatment of CRLM.
Model-Driven Security based on A Unified System of Security Design Patterns

Model-Driven Security (MDS) for secure systems development still has limitations to be more applicable in practice. A recent systematic review of MDS shows that current MDS approaches have not dealt with multiple security concerns systematically. Besides, catalogs of security patterns which can address multiple security concerns have not been applied efficiently. This paper presents an MDS approach based on a unified System of Security design Patterns (SoSPa). In SoSPa, security design patterns are collected, specified as reusable aspect models to form a coherent system of them that guides developers in systematically addressing multiple security concerns. SoSPa consists of not only interrelated security design patterns but also a refinement process towards their application. We applied SoSPa to design the security of crisis management systems. The result shows that multiple security concerns in the case study have been addressed by systematically integrating different security solutions.
Simulation of unified static VAr compensator and power system stabilizer for arresting subsynchronous resonance

In the literature, the co-ordination of static VAr compensators (SVC) and power system stabilizers (PSS) using generator speed deviation or modal speeds such as stabilizing signals is shown to damp power system oscillations. Though such schemes are able to damp the SSR modes for small disturbances, they are unable to damp transient SSR due to large disturbances. In this report, an improvement in the control aspect of the SVC at the midpoint of the power transmission line is suggested. This scheme attempts different auxiliary signals that include line current, computed internal frequency and bus angle deviations. A system of configuration similar to IEEE First Bench Mark model is considered, eigenvalue analysis has been carried out and results indicate that bus angle deviation signal as an auxiliary control signal for SVC was able to damp most of the modes leaving some of them still oscillatory. The main feature of the proposed work is to use a combination of the deviation in speed and electrical power output of the generator as input signals to PSS which operates simultaneously along with SVC. Such a simultaneous PSS and SVC scheme is found to improve power system damping under large disturbances, i.e. the growth of system oscillations is arrested. Control simulations are carried out on PSCAD. The efficacy of controllers to damp SSR under steady state and faulted conditions, where one of the torsional modes is excited, is presented and discussed.
Analyses on the mechanism of a Convective Cloud System over the ishikari Plain on September 23, 1988

Most severe storms that occur over the Ishikari Plain are concentrated in a specific area: the eastern suburb of Sapporo and the central area of the Ishikari Plain. To analyze the structure and mechanism of a convective cloud system which developed over the Ishikari Plain, Hokkaido, we investigated a severe storm which developed on September 23, 1988 using the results of the Doppler radar observation, ground and upper meteorological data, and three-dimensional numerical simulations using the moist cloud model developed by Y oshizaki and Ogura (1988). The results of the Doppler radar observation show that this convective cloud system propagated from the seaside area to the inland area over the Ishikari Plain. The convective cloud system was organized as a line oriented north-south propagating from the seaside area to the inland area. The orientation of the system upon reaching the inland area changed to southwest-northeast. From the results of the surface observations, a difference in the wind direction and speed near the ground between the seaside area and the inland area is considered in performing the numerical simulations and we obtained the results that this difference brought about the change in the orientation of the convective cloud system derived from the convergent area between the lower inflow (generally southerly or southeasterly wind) and the divergent flow from the system.
Impact of climate change on water balance of forest sites in Rhineland-Palatinate, Germany

Abstract. It is expected that the biomass productivity of forest stands will be influenced by global climate change. In order to adapt forest management to this fact a model based approach was developed in cooperation with forestry experts. The concept aims at detecting the link between climate, terrain and soil parameters with the biomass productivity of some tree species. This article gives an insight into the first two steps of this approach. At first the WaSiM-ETH 8.2 model was parameterised to simulate various forest sites. Furthermore, different drought stress indices were applied to the simulated water balance time series. The impact of variations of climate, topography and soil characteristics on water balance was plausibly simulated. All drought stress indices detected years which were dominated by dry conditions. However, the indices related to soil water content were more selective than those related to evapotranspiration. Drought stress indices for one future climate projection have shown an increasing frequency of drought stress during vegetation period. Thus, the first two steps are capable components to detect the link between water balance with climate, terrain and soil parameters.
Model of Emotional Expressions in Movements.

This paper presents a new approach to automated identification of human emotions based on analysis of body movements, a recognition of gestures and poses. Methodology, models and automated system for emotion identification are considered. To characterize the person emotions in the model, body movements are described with linguistic variables and a fuzzy hypergraph for temporal events, which are transformed into the expression in a limited natural language.
Tsunami damping by mangrove forest: A laboratory study using parameterized trees

Abstract. Tsunami attenuation by coastal vegetation was examined under laboratory conditions for mature mangroves Rhizophora sp. The developed novel tree parameterization concept, accounting for both bio-mechanical and structural tree properties, allowed to substitute the complex tree structure by a simplified tree model of identical hydraulic resistance. The most representative parameterized mangrove model was selected among the tested models with different frontal area and root density, based on hydraulic test results. The selected parameterized tree models were arranged in a forest model of different width and further tested systematically under varying incident tsunami conditions (solitary waves and tsunami bores). The damping performance of the forest models under these two flow regimes was compared in terms of wave height and force envelopes, wave transmission coefficient as well as drag and inertia coefficients. Unlike the previous studies, the results indicate a significant contribution of the foreshore topography to solitary wave energy reduction through wave breaking in comparison to that attributed to the forest itself. A similar rate of tsunami transmission (ca. 20%) was achieved for both flow conditions (solitary waves and tsunami bores) and the widest forest (75 m in prototype) investigated. Drag coefficient CD attributed to the solitary waves tends to be constant (CD = 1.5) over the investigated range of the Reynolds number.
Analysis Based Music Ratification

The aim of this paper is to present an approach to music rating by performing sentiment analysis using supervised learning methods. The recent boost of use of web has resulted in large quantities of user generated data being created every day. People use the web now, to review any product from different sectors like food, electronics. Enterprises too have realized the value of online feedback for future sales. Though sentiment analysis has largely been employed in movie reviews and product recommendation systems, it has largely been kept away for the music portal. The current music charts largely rely on the number of downloads, number of air plays, and physical sales of the songs. This paper though limited to theoretical discussion, aims to create a new ranking system with more emphasis on user opinion, to see if there is a disparity in these two approaches and also reviews the related work done in this field.
COMPILER OPTIMIZATIONS FOR POWER-

In embedded systems, off-chip buses and memory (i.e., L2 memory as opposed to the L1 memory which is usually on-chip cache) consume significant power, often more than the processor itself. In this paper, for the case of an embedded system with one processor chip and one memory chip, we propose frequency and voltage scaling of the off-chip buses and the memory chip and use a known micro-architectural enhancement called a store buffer to reduce the resulting impact on execution time. Our benchmarks show a system (processor + off-chip bus + off-chip memory) power savings of 28% to 36%, an energy savings of 13% to 35%, all while increasing the execution time in the range of 1% to 29%. Previous work in power-aware computing has focused on frequency and voltage scaling of the processors or selective power-down of sub-sets of off-chip memory chips. This paper quantitatively explores voltage/frequency scaling of off-chip buses and memory as a means of trading off performance for power/energy at the system level in embedded systems.

Performance of Sudanese Agricultural Exports: A Gravity Model Analysis

This paper aims at identifying the determinants of Sudanese agricultural exports using a gravity model for for a sample of 31 trading partners, over the period 1995-2011. In addition, the paper investigates whether there is unexploited trade potential between Sudan and its trading partners within this sector. The empirical results show that importer’s GDP and population size exert positive and significant impact on agricultural exports. The results also point out that both domestic and trading partner’s infrastructure play positive and significant role in enhancing exports performance. The impact of geographical distance is found to be negative and significant on exports as expected. Moreover, the results reveal that Arabic speaking countries and COMESA members have strong tendency to receive agricultural exports from Sudan. Furthermore, the analysis shows that export potential exists with a number of trading partners such as Oman, Spain, Poland, Singapore and Japan. Finally, the paper ends with some policy recommendations aiming at guiding effective strategy to improve the perfromance of Sudanese agricultural exports.
School Uniforms: Tradition, benefit or predicament?

Abstract This article focuses on the controversies surrounding school uniforms. Roleplayers in this debate in South Africa are parents, learners and educators, and arguments centre on aspects such as identity, economy and the equalising effect of school uniforms, which are considered in the literature to be benefits. Opposing viewpoints highlight the fact that compulsory uniforms infringe on learners’ constitutional rights to self-expression. The aim of this research was to determine the perspectives of parents, learners and educators at public schools in Vanderbijlpark, South Africa, on obligatory school uniforms. A structured questionnaire was used to gather data. A random stratified sample of learners, and their parents and educators was chosen. Results revealed that most parents and educators, and nearly two-thirds of the learners were highly in favour of school uniforms. Regarding the advantages and disadvantages of eight factors pertaining to obligatory school uniforms, the educators rated seven of .

Entrepreneurs as authentic leaders: impact on employees' attitudes

Purpose – The leadership of entrepreneurs/business founders, as perceived by their employees, has received limited research attention. Using the Authentic Leadership Model as a guiding framework, this study seeks to provide an exploratory examination of the linkage between employees' perception of the business founder as an authentic leader and the employees' attitudes and happiness.Design/methodology/approach – Participants are employees (n=179) of 62 newer, smaller businesses. Each business represented in the study had been founded by a single owner still active in the daily operations of the company. Hierarchical linear modeling was used to analyze the two levels of data (individual and business level) gathered in the study.Findings – As hypothesized, the employees' perception of authentic leadership serves as the strongest single predictor of employee job satisfaction (t=6.453, p=0.000), organizational commitment (t=6.665, p=0.000), and work happiness (t=5.488, p=0.000).

TITRE DE LA THESE NMDA RECEPTOR EXPRESSION CHANGES ON VENTRAL TEGMENTAL (VTA) DOPAMINE NEURONS AFTER ACUTE COCAINE EXPOSURE THESE

Drug-evoked synaptic plasticity in the mesolimbic dopamine system reorganizes neural circuits that may lead to addictive compulsive behavior. The first cocaine exposure potentiates AMPAR excitatory postsynaptic currents (EPSCs) onto DA neurons of the VTA, but reduces the amplitude of NMDAR-EPSCs. While the plasticity of AMPA transmission is expressed by insertion of calcium (Ca2+)-permeable GluA2-lacking receptors, little is known about the expression mechanism for the altered NMDAR transmission. Combining ex vivo patch clamp recordings, mouse genetics and subcellular Ca2+ imaging, we observe that cocaine drives the insertion of NMDARs that are quasi Ca2+-impermeable and contain GluN3A and GluN2B subunits. These GluN3A-containing NMDARs appear necessary for the expression of cocaine-evoked plasticity of AMPARs. We identify an mGluR1 dependent mechanism to remove these "non-canonical" NMDARs that requires Homer/Shank interaction and protein synthesis. Our data provide insight into the early cocaine-driven reorganization of glutamatergic transmission onto DA neurons and offers GluN3A-containing NMDARs as a
