Wiseman–Milburn control for the Lipkin–Meshkov–Glick model

We apply a measurement-based closed-loop control scheme to the dissipative Lipkin–Meshkov–Glick model. Specifically, we use the Wiseman–Milburn feedback master equation to control its quantum phase transition. For the steady state properties of the Lipkin–Meshkov–Glick system under feedback we show that the considered control scheme changes the critical point of the phase transition. We show that entanglement measures such as concurrence allow one to unambiguously locate precursors of quantum-critical behaviour in the finite-size regime, unlike conventionally used operator expectation values. We find that with feedback, the position of the critical point can be shifted to smaller spin–spin interactions, which is potentially useful for setups with limited control on these.
Cyclic vectors and invariant subspaces for Bergman and Dirichlet shifts

It is shown that the invariant subspaces for the Bergman and Dirichlet shifts on the right half-plane correspond to the common invariant subspaces of the right shift operators on certain weighted Lebesgue spaces on the half-line. As a particular instance, the corresponding result for invari- ant subspaces of multipliers induced by weak-star generators ofH ¥ (D) on weighted Bergman spaces of the unit disc is deduced. Finally, cyclic vectors for the Bergman and Dirichlet shifts are also studied.
EFFECT OF PEER EDUCATION ON HEALTH PROMOTING BEHAVIORS OF JUNIOR HIGH SCHOOL STUDENTS

Background and Objective: One of the ways to achieve healthy communities is training adolescents in healthy behaviors. This study was conducted to assess the impact of peer education approach to health promoting behaviors in Bastak junior high school students. Methods: The study population was junior high school students in Bastak coun - ty, Hormozgan. In this semi-experimental study 201 students were placed in the intervention group and 157 students in the control group. The data were collected through The Adolescent Health Promotion Scale. The questionnaire measures health promoting behaviors in six areas, including nutrition, social protection, health personal responsibility, valuation of health, exercise and stress management. Intervention was performed through peer education. Data were collected before and two months after the intervention and analyzed by using SPSS19 and independent and paired t-test. Results: Health promoting behaviours scores showed a significant increase in the intervention group except health valuation area compared with pre-train - ing (p<0.001) while the control group showed a significant decrease in average behavioral in all domains (p<0.05). After the intervention, students' health pro - moting behaviors in all six areas including nutrition, social protection, health personal responsibility, valuing health, exercise and stress management in the intervention group were statistically significant compared with control group (p<0.001). Conclusion: This study showed that peer education approach can be effective in changing the behavior of young adults towards healthy behaviors. Paper Type: Research Article.
The Long-Run Effects of Attending an Elite School: Evidence from the UK

This paper estimates the impact of elite school attendance on long-run outcomes including completed education, income and fertility. Our data consists of individuals born in the 1950s and educated in a UK district that assigned students to either elite or non-elite secondary schools. Using instrumental variables methods that exploit the school assignment formula, we find that elite school attendance had large impacts on completed education. For women, we find that elite school attendance generated positive effects on labor market outcomes and significant decreases in fertility; for men, we find no elite school impacts on any of these later-life outcomes.
Mesh-free methods for transient heat conduction

The paper deals with transient heat conduction in functionally gradient materials. The spatial variation of the temperature field is approximated by using alternatively two various mesh free approximations, while the time dependence is treated either by the Laplace transform method and/or by the polynomial interpolation in the time stepping method. The accuracy and convergence of the numerical results as well as the computational efficiency of various approaches are compared in numerical test example.
A global model of meteoric sodium

A global model of sodium in the mesosphere and lower thermosphere has been developed within the framework of the National Center for Atmospheric Research's Whole Atmosphere Community Climate Model (WACCM). The standard fully interactive WACCM chemistry module has been augmented with a chemistry scheme that includes nine neutral and ionized sodium species. Meteoric ablation provides the source of sodium in the model and is represented as a combination of a meteoroid input function (MIF) and a parameterized ablation model. The MIF provides the seasonally and latitudinally varying meteoric flux which is modeled taking into consideration the astronomical origins of sporadic meteors and considers variations in particle entry angle, velocity, mass, and the differential ablation of the chemical constituents. WACCM simulations show large variations in the sodium constituents over time scales from days to months. Seasonality of sodium constituents is strongly affected by variations in the MIF and transport via the mean meridional wind. In particular, the summer to winter hemisphere flow leads to the highest sodium species concentrations and loss rates occurring over the winter pole. In the Northern Hemisphere, this winter maximum can be dramatically affected by stratospheric sudden warmings. Simulations of the January 2009 major warming event show that it caused a short‐term decrease in the sodium column over the polar cap that was followed by a factor of 3 increase in the following weeks. Overall, the modeled distribution of atomic sodium in WACCM agrees well with both ground‐based and satellite observations. Given the strong sensitivity of the sodium layer to dynamical motions, reproducing its variability provides a stringent test of global models and should help to constrain key atmospheric variables in this poorly sampled region of the atmosphere.
The Green Paradox in Open Economies

This paper explains how, in the context of incomplete coordination among all countries, unilateral policies that might at first sight seem pro-green could actually turn out to harm the global environment. The free-riding motives and the difficulty of reaching an effective international environmental agreement are reviewed. As a first step, the various channels that lead to carbon leakage in static models of open economies are identified, and some simulation results are reported. This is complemented by a review of the possibility of green paradox outcomes in dynamic open-economy models with an exhaustible resource exploited by far-sighted firms. It is shown that border tax adjustments can lead to a green paradox outcome. Directions for future research are suggested.
A study of Improving Energy Efficiency of small supermarkets by modelling interaction between building, HVAC, Refrigeration and display product.

There is evidence that food retail has shifted towards smaller stores and food products requiring less time for cooking. Small supermarkets (<400m) usually located within urban areas have higher energy intensity than larger supermarkets because of the high ratio of food against non-food products. An energy and thermal small supermarket model was developed based on EnergyPlus using a coupling approach on the interdependence of subsystems and verified with operational data. Simulations of energy efficient retrofits indicate savings of up to 17% with integrated improvements of building design, lighting, refrigeration and HVAC systems. Analysis of refrigeration type and food ratios indicates reduction of total and refrigeration energy consumption with decreasing frozen foods, but increase for the HVAC system making its choice more critical. Location within the urban heat island also has a small impact on the total energy use more pronounced for the HVAC and depending on the refrigeration system.

Diacylglycerol acyltransferase ( DGAT ) activity in relation to muscle fat content and DGAT 1 genotype in two different breeds of

To circumvent the obvious waste of resources when producing good marbled beef, research is needed to clarify mechanisms which are involved in intramuscular fat storage in cattle. The possible association between the activity of diacylglycerol acyltransferase (DGAT) and muscle fat content was examined in samples of longissimus dorsi (LD) and semitendinosus (ST) muscle from Holstein and Charolais bulls. The Holstein bulls exhibited higher fat content in both muscles and higher marbling score. In Holstein, DGAT activity was enhanced in the LD muscle, and there was a tentative positive relationship between DGAT activity and the fat content in ST muscle. When muscle DGAT activity was examined as a function of DGAT1 genotype for all animals, regardless of breed, the DGAT activity of LD muscle of the K/K genotype was about five-fold greater than for either the K/A or A/A genotypes. Further investigation on the relationship between DGAT1 genotype and i.m. fat is required before this may be developed as a selection tool for marbling.
The magnitude, determinants and barriers for physical activities among diabetic patients in Qassim area of Saudi Arabia

Background: To review the level of physical activity (PA) among adult diabetics and barriers to PA in this population. Methods: This survey was performed in 2017 and enrolled adult diabetics from primary health center of the National Guard in Qassim, Saudi Arabia. International Physical activity questionnaire was used to grade the level of PA. The three intensities of PA (walking, moderate and vigorous exercise), and number of days per week and hours per day were queried for each participant. Metabolic equivalent (MET), a proxy indicator of PA was calculated. Data were analyzed for associations to demographic and diabetes-related factors. Participants were queried on barriers to PA such as time, space, high cost, physical disability, preoccupation with other priorities and languor. Results: We interviewed 395 diabetic patients. The low and moderate levels of PA were noted for 320 (81%) and 75 (19%) participants respectively. None had a high level of PA. Gender (P=0.4), age (P=0.45), body mass index (P=0.66) were not associated to PA. Joint problems (43%), languor (35.2%) and family time (33.9%) were the main barriers that lowered PA. Conclusions: There was a low level of PA among diabetics in Qassim. Barriers to PA should be proactively addressed during patient counseling to improve PA in this population. Counseling direct towards increasing PA may mitigate the physically disabling complications of cardiovascular events among diabetics.
A Method of Inquiring Ontology with Semantic Templates

It is always a challenge by using statistical method in corpus database to analyze semantics of natural language Sentences (NLS). This paper proposes a method of recognizing and translating ontology query in natural language, called OntoQuery-NLP. With the help of pre-create semantic templates, the OntoQuery-NLP maps NLSs matching the format of the semantic templates into formal semantic expressions. By parsing these semantic expressions, the OntoQuery-NLP recognizes the queries and gets the correct answers from ontology. Compared with other methods, the OntoQuery-NLP, without the support of any corpus, has faster retrieving speed and higher retrieving accuracy.
Interactive comment on “Early warning signals in complex ecosystems” by I. S. Weaver and J. G. Dyke

The manuscript uses an abstract set of multidimensional, coupled nonlinear ODEs to model a conceptual ecosystem. They find the model has fixed point solutions and these fixed point solutions can loose stability through local bifurcations when parameters are varied via critical slowing down. They confirm this (i) by analytical computation of the fixed point and its Jacobian using the model equations directly and (ii) by computing the usual early warning signals of impending local bifurcations autocorrelation, variance and skewness of numerical simulations of the variable’s time series.
Enhanced Physics Schemes for the 2D NS-alpha Models of Incompressible Flow

In this thesis, we study algorithms for the 2D NS-α model of incompressible flow. These schemes conserve both discrete energy and discrete enstrophy in the absence of viscous and external forces, and otherwise admit exact balances for them analogous to those of true fluid flow. This model belongs to a very small group that conserves both of these quantities in the continuous case, and in this work, we develop finite element algorithms for the vorticity-stream formulation of this model that will preserve numerical energy and enstrophy in the computed solutions.
Data-informed Instructional Leadership: Improving the Instructional Program in South African Primary Schools

Abstract Managing an instructional program is recognized as constituting a major area of focus for successful school leadership. Linked to this recognition is the acknowledgement of the importance of the school principal in improving performance in this area and accounting for decisions made in the process. To improve learner performance and strengthen accountability, principals are encouraged to turn to data. This enables them to examine performance, generate informed decisions and plan for sustainable improvement. In this study, current school performance and leadership practices in South Africa are examined against a literature background. Based on a qualitative study, this paper examines specifically how principals in South African primary schools use data to manage the instructional program. The paper shows challenges which principals face in improving learner performance without the capacity for effective data use. One key finding is that school leaders lack capacity to create a culture of collaborative enquiry in schools.
Disturbance-related patterns in unstable rocky benthic habitats of the north-eastern Baltic coast

Distinct patterns of benthic flora and fauna are produced when unstable rocky substrata are disturbed by water motion. This study investigated occurrence of disturbance-related patterns in benthic boulder habitats on the north-eastern Baltic coast. Sessile assemblages, mostly algae on tops of boulders and barnacles and bryozoans underneath, were found to differ between small (50–150 cm2 upperside surface area) and large (200–800 cm2) boulders. Densities of motile gammaridean amphipods were negatively correlated with boulder size. These patterns may be due to small boulders being displaced by water motion more frequently than large ones. Most of the barnacle shells/tests were remnant empty ones, and the proportion of empty tests and living barnacles was similar underneath small and large boulders, suggesting that degradation/removal of empty tests was not influenced by disturbance associated with boulder size. There was no consistent evidence of algae being affected by boulder size, but the tops of boulders had less algae than the edges, a pattern that is typically associated with high rates of overturning. Confirmation of disturbance as having caused these patterns and thus being an important process for structuring benthic biota in this region could be achieved by further manipulative experimentation.
Market Access and Rural Poverty in Tanzania

Economic reforms in Tanzania have resulted in low inflation and solid economic growth, but many observers question whether the standard of living of ordinary Tanzanians has improved. Furthermore, there is a strong suspicion that the benefits have been concentrated among the urban population and among rural households with good market access, leaving remote rural households behind. In this paper, we demonstrate a new approach to measuring poverty trends over time. First, the relationship between poverty and household characteristics is estimated using household budget survey data. Second, this relationship is applied to the same characteristics in Demographic and Health Surveys, four of which have been carried out in Tanzania. The results suggest that the headcount poverty rate has declined by almost 9 percentage points over 1991-2003. The percentagepoint decline has been similar in rural and urban areas. Although remote rural areas tend to be poorer than other rural areas, there is no evidence that remote areas have gained any less than other rural areas in terms of poverty reduction.
Enzymatic Chromium (VI) Reduction by Cytoplasmic and Cell Membrane Fractions of Chromate-Reducing Bacterium Isolated From Sewage Treatment Plant

Hexavalent chromium is a toxic heavy metal in environment. To remove it from the system, reduction to the trivalent form using microorganisms is an alternative cost-effective method compared to the conventional physicochemical methods. Bacillus cereus Pf-1was isolated and tested for the reduction potential of Cr (VI) using different sub-cellular fractions. Diphenylcarbazide method was used to measure the remaining Cr (VI) concentration in supernatant after centrifugation, and the pellet was used for Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray (EDX) analysis. Almost complete reduction of Cr (VI) was reported for initial Cr (VI) concentration from 10-50 mg/L. Assay with permeabilized cells (treated with Toluene and Triton X-100) and cells free assay demonstrated that Cr (VI) reduction activity was mainly associated with the cytoplasmic fraction of the cells. Considering the major amount of Cr (VI) being reduced within 24 h, the chromate reductase could have been released during growth. Additionally, SEM analysis showed that Bacillus cereus treated with Cr (VI) grew well and had uniform size. EDX analysis revealed certain amounts of chromium in cells treated with Cr (VI). Based on this, Bacillus cereus Pf-1 could be considered as a potential reducing agent for Cr (VI) in aqueous solutions.
Lightning fast asynchronous distributed k-means clustering

One of the most fundamental data processing approach is the clustering. This is even true in distributed architectures. Here, we focus on the problem of designing efficient and fast K-Means approaches which work in fully distributed, asynchronous networks without any central control. We assume that the network has a huge number of computational units (even orders of magnitude more than the number of computational units in a general cloud). Our approaches apply online learning clustering models which take different random walks in the network, while they update themselves using the data points stored by the computational units, and various ensemble techniques combine them to get a faster convergence. We define different instantiations of the general framework that apply various ensemble techniques. We evaluate them empirically against several state-of-the-art distributed baseline algorithms in different computational scenarios. The experiments show that our methods are not only robust against network failure, but they also provide accurate clustering and converge extremely fast.
Family Influences on Intermarriage Attitudes: A Sibling Analysis in the Netherlands

This study examined the influence of the family on native Dutch attitudes toward having ethnic minority members as kin through marriage using multiactor data from the Netherlands Kinship Panel Study (N = 1,652). Results from multilevel models showed that 28% of the variation in ethnic attitudes can be ascribed to the family. We investigated different pathways through which the family affects these attitudes; 60% of the family influence was explained. Results revealed that the intergenerational congruence of attitudes and the transmission of attitudes and structural and cultural positions are important mechanisms. Furthermore, family characteristics in adulthood—strength and warmth of family relationships—related to intermarriage attitudes, and the strength of family relationships moderated attitude congruence within families.
Online Advertising: An Investigation of Factors Affecting Positive Attitude among the Malays in Malaysia

The aim of this research is to inestigate about attitudes toward online advertising (ATOA) among Malays. Data were collected from Malays above eighteen years old with Internet usage experiences. Four belief factors that underline Malays consumers’ attitudes toward online advertising were identified: informativeness, hedonism, credibility and good for economy. The findings from this research indicated that informativeness, hedonism and good for economy had significant impacts on ATOA among Malays. The research provides potentially useful insights and directions for marketers in order to optimize the results of their online advertising campaigns among Malays in Malaysia.
IMPACT OF LEADERSHIP STYLE AND TEAM CONTEXT ON PSYCHOLOGICAL EMPOWERMENT IN CONSTRUCTION PROJECT TEAMS

The empowerment process makes huge demands on organizations and its constituents. The team as the proximal work environment creates a social environment for interactions that can change individual behaviour, attitudes and perceptions. Leadership provides a direct channel through which individuals interpret organizational policies and practices. The impact of leadership style and team context on psychological empowerment in project teams was examined using data from a parallel questionnaire survey of construction client, consultant and contractor organizations in Hong Kong. It was posited that span of control and interdependence will positively and significantly influence psychological empowerment. Person orientated leadership style was expected to positively impact psychological empowerment while task orientated leadership style was expected to have a negative impact. No significant relationship was found between span of control and psychological empowerment while team interdependence had a positive and significant relationship with psychological empowerment. Task orientated leadership was positively and significantly related to psychological empowerment in the full sample and contractor teams but not in consultant and client teams. Person orientated leadership was positively and significantly related to psychological empowerment in the full sample, consultant and client teams but not in contractor teams. The distinct findings in relation to the leadership style-empowerment link are consistent with a systems perspective of the construction process. Client and consultant teams constitute a "managing sub-system" and rely on management of interrelationships (i.e. person orientated leadership) to succeed while contractor teams constitute the "operating/task sub-system" and rely on task performance (i.e. task orientated leadership). The findings add to the growing evidence of lack of support for the stereotypical views on how task and person orientated leadership styles manifest. In project settings where "getting the job done" and "teamwork" are inseparable both leadership styles can produce positive outcomes through "leadership adjustment".
