The orchestration of processes in relation to the product, and the role of psychological variables in written composition

We studied the timing of writing processes using a direct retro- spective online technique, and differences in the textual product from the earliest school years where such a study is feasible to the final years of compulsory education. We also analysed a range of psychological variables to determine their modulating effect on writing. Participants comprised a highly purified sample of 348 students aged between 9 and 16 years old who presented standard development and average levels of curricular and writing competence. Our results reveal complex patterns in the develop- ment of the writing process and its orchestration, compared with the textu- al product, and no direct relationship was observed between development of the writing process and its timing, and improvement in the textual prod- uct. Among the youngest students, all this was mediated by psychological variables related to the existence of inaccurate perceptions of self-efficacy as regards the deployment and use of writing processes and causal attribu- tions to external factors. The implications, limitations and future perspecti- ves are discussed.
Characterization of Historical Seasonal and Annual Rainfall and Temperature Trends in Selected Climatological Homogenous Rainfall Zones of Uganda

There is general lack of scientific consensus on the trend and distribution of annual and seasonal rainfall and temperature in Uganda. This study used both observational and AgMerra rainfall and temperature data for the period 1980-2010 to characterize the trend and variability in seasonal and annual rainfall, maximum and minimum temperatures across 12 different rainfall homogenous zones (K, H, ME, L, J, F, MW, D, E, A1, A2, and I) of Uganda. Trends analysis was done using regression method, while coefficient of variation and ANOVA techniques were used to analyze variability. The results show statistically significant increasing trends (P ≤ 0.05) in annual rainfall amount in zone A1 and a declining trend for zone K (P<0.05).
Survivability of IEEE 802.11 Wireless LAN Against AP Failure

In IEEE 802.11 WLAN, if an access-point fails, some or all the mobile stations connected to the network via the access-point may lose connectivity. In this paper, the problem of enhancing the survivability of IEEE 802.11 WLAN focusing on tolerating Access Point (AP) failures is addressed. In particular, focus on the problem of overcoming these APs failure working with reconfiguration of the remaining APs by changing parameters like the neighboring AP’s MAC address is done. This approach consists of two main phases: Design Phase and Fault Response. In Design phase, we deal with quantifying, placement and setting up of APs according to both area coverage and performance criteria. In Fault Response phase we consider the reconfiguration of the active APs in order to deal with AP fault in the service area.
Psychological and psychobiological stress in the relationship between basic cognitive function and school performance

This study analyses the role played by daily stress, assessed through self-report and at the psychobiological level, in relation to basic cognitive function when predicting school performance. The sample com- prised 100 schoolchildren (55 girls and 45 boys, age range 8 to 11 years) from a state school in the city of Malaga (Spain). Daily stress was assessed through the Children"s Daily Stress Inventory (IIEC in Spanish; Trianes et al., 2009). Psychobiological stress was measured through the corti- sol/DHEAS ratio, derived from saliva samples taken in the morning on two consecutive days. Basic cognitive skills were assessed by means of the Computerized Cognitive Assessment System (CDR battery; Wesnes et al., 2003, 2000). Finally, the measure of school performance was the mean val- ue of the final grades recorded in the child"s school report. In addition to descriptive and correlational statistical analyses, multiple regression analyses were conducted in order to assess the model. The results show that chil- dren"s daily stress self-reported contributes to predict school performance, and has proven to be more influential than basic cognitive function when it comes to predict school performance. Therefore, in order to achieve good school performance, a pupil not only requires good basic cognitive func- tion, but must also present low levels of self-reported daily stress. These findings suggest a new way of explaining and predicting school failure.
My Collaboration with Raj Mittra: Contributions to the Theory of Perfectly Matched Layers

It is impossible to imagine a young researcher in the vast field of applied electromagnetics to not have encountered the name of Raj Mittra during the first few months of his research activities. In 1980, I came across an article written by Professor Mittra when I was working on my M.Sc. thesis, on transient electromagnetics, long before I met him personally in October 1995, in Urbana-Champaign. During the interim 15 years, comprising my Master’s and Ph.D. thesis and post-doctoral studies, I came to read and use several of Mittra’s papers and books, as his contributions span nearly the entire field of electromagnetics, and distinguished by the elegance of his intuition, mastery of analytical and numerical methods and pertinence of problem selection to the real world. I was thus quite excited on the evening of October 15, 1995 when, for the first time, I met Raj Mittra at Urbana-Champaign airport. This was the first day of my approximately one year visit to the University of Illinois as a NATO scholar. We talked about several things during the ride to my apartment but I remember that he was especially pleased to learn that my major research area is FEM (Finite Element Method), since it was also an area Prof. Mittra had worked in extensively. The next day I visited the Electromagnetic Communications Laboratory and, as a lucky coincidence, happened to be a seminar on one of the year’s hot topics. The speaker was one of Mittra’s Ph.D. students, J. C. Veihl, and the subject was the utilization of PMLs (Perfectly Matched Layers) in FDTD applications. Though unable to recall the details of this talk (as I was under the spell of severe jet-lag) I do remember being intrigued by the idea of a layer capable of absorbing electromagnetic waves irrespective of frequency and direction of incidence. During the seminar, I did not know that this topic would be one of my favourite research subjects in the coming years. In the first few months of my collaboration with Raj Mittra, we concentrated on the usage of PMLs in FEM applications. The PML concept was originally introduced by J. P. Berenger in his 1994 paper as a grid truncation approach in FDTD applications [1]. Berenger’s approach was based on a field-splitting approach yielding non-Maxwellian fields within the PML. A formulation where the PML was realized as an anisotropic layer was achieved by Sacks et al. [2] and our main concern was to extend the idea of this layer sandwiched between planar surfaces to an arbitrary layer between curved surfaces. The main motivation behind this was the possibility of designing a PML conformal to the surface of a scatterer (or antenna). I remember working on this exciting project during the winter of 1995–96. Our joint work spanned a few short months, but was extremely exciting for me since the subject was very interesting and our
Definition of Done from Academy to the Industry: An Exploratory Survey

— Definition of Done (DoD) assures a balance between short-term delivery of features and long-term product quality. The state of the art of this area was documented in a Systematic Literature Review (SLR), which found 8 papers. This study reports findings on the usage of DoD based on the SLR results, focusing on aspects such as which criteria are used and the process in which they are defined and assessed. A survey was carried out using on-line questionnaires answered by practitioners. Data was collected from agile practitioners from 16 countries and different team sizes, and the main findings are: 1) Quality management is the most popular type of criteria; (2) DoD are not defined following a standard; 3) Most projects use a single level DoD; 4) DoD is emergent during a project; 5) The criteria are visible; 6) Most projects assess DoD manually; 7) There are no empirical evidence of its effectiveness; (8) Most challenges are related to the risk of over effort and reaching agreement among stakeholders; and (9) a new criteria were reported, deploy. The main implication for research is a need for empirical studies exploring the its use. For the industry, the results can assist the definition of their own.
Environmental Determinants of Child Mortality in Rural China: A Competing Risks Approach

We use a competing risk model to analyze environmental determinants of child mortality using the 1992 China National Health Survey, which collects information on cause of death. Our primary question is whether taking into account of cause of death using a competing risk model, compared with a simple model of all-cause mortality, affects conclusions about the effectiveness of policy interventions. There are two potential analytical advantages in using cause of death information: (1) obtaining more accurate estimates and (2) validating causal relationships. Although, we do not find significant differences between estimates obtained from the competing risk model and those from simpler hazard models, we do find evidence supporting the causal interpretations of the effect of access to safe water on child mortality. Our analysis also suggests that a respondent-based health survey can be used to collect relatively reliable information on cause of death. Modifying future demographic and health survey (DHS) instruments to collect cause of death information inexpensively may be worthwhile for enhancing the analytical strength of the DHS.
Kefir - grains and beverages: a review

Kefir is a fermented milk beverage produced by the action of bacteria and yeasts that exist in symbiotic association in kefir grains. The large number of microorganisms present in kefir and their microbial interactions, the possible bioactive compounds resulting of microbial metabolism, and the benefits associated with the use this beverage confers kefir the status of a natural probiotic, designated as the 21th century yoghurt. The importance of probiotics in food industry is growing nowadays and further research should be performed on the symbiotic relations between different microorganisms and how these interactions can result in nutritional and therapeutic benefits as curing and preventing human diseases and other disorders. This review includes a thorough and detailed discussion on the structure, microbiological and chemical composition, and the production and utilization of kefir will be presented covering different aspects.
Two Hybrid Methods for Solving Two-Dimensional Linear Time-Fractional Partial Differential Equations

A computationally efficient hybridization of the Laplace transform with two spatial discretization techniques is investigated for numerical solutions of time-fractional linear partial differential equations in two space variables. The Chebyshev collocation method is compared with the standard finite difference spatial discretization and the absolute error is obtained for several test problems. Accurate numerical solutions are achieved in the Chebyshev collocation method subject to both Dirichlet and Neumann boundary conditions. The solution obtained by these hybrid methods allows for the evaluation at any point in time without the need for time-marching to a particular point in time.
Prevalence of metabolic syndrome in young adults: a study from North India

Background: Metabolic syndrome is a cluster of risk factors for CVD and is on rise globally as well as in india. Methods: This was a population based study conducted on 356 individuals of the age of 16-45 years, attending Medicine OPD for routine check-up at Sri guru ram das institute of medical sciences and research. Participants were subjected for anthropometric measurements, complete physical examination and evaluation of biochemical parameters in context of metabolic syndrome. Results: On applying, NCEP-ATPIII criteria, the prevalence of MS was found to be 22.47%. The prevalence of MS was comparable in both genders, though MS was significantly higher in females of 36-45 years age group (25.64%). About 82% of the participants were either overweight or obese. Conclusions: Since obesity was the most common entity prevalent and a major risk factor for MS and CVD, early detection and lifestyle modifications to prevent obesity and dyslipidemia should be promoted at all levels in community.

Analysing wellbeing: a framework for development practice

This article presents a framework for analysing wellbeing in development practice, drawing on the work of the Wellbeing in Developing Countries Research Group (WeD). Wellbeing is viewed as a social process with material, relational, and subjective dimensions. Wellbeing may be assessed at individual and collective levels, but at base is something that happens in relationship – between individual and collective; between local and global; between people and state. The article considers potential hazards in taking wellbeing as focus, and concludes by considering what real difference such a focus could make.
Why the determinacy condition is a weak criterion in rational expectations models

This paper disputes what Blanchard and Kahn have reported as the solution of linear rational expectation(RE) systems many years ago. Their method leads to traditional determinacy condition which is used very much nowadays. In this paper we have a new look to the mathematical procedure of this solution method and the main problem in their solution will be shown. We introduce a new methodology for modeling the systems with expectation, while in future this way of modeling can be used to replace traditional RE models.
THE RELATIONSHIP BETWEEN ACADEMIC ACHIEVEMENT AND SATISFACTION: EVIDENCE OF MODERATING EFFECTS FOR ACADEMIC AND SOCIAL INTEGRATION

Building on previous research, this study examined the reciprocal relationship between academic achievement and satisfaction of 1001 seniors at the University of Missouri-Columbia. Students completed a survey which measured overall satisfaction, ratings of academic and social experiences, whether the student would recommend the university to a friend, perceived academic effort, satisfaction with their achievement, and perceived social integration. Survey results were compared with the students' academic ability and achievement data. Data were analyzed using two sets of structural equation models. Results indicated that the relationship between satisfaction and achievement was an artifact of other aspects of students' college experiences, namely academic and social integration.

The KMOS Deep Survey (KDS) II: The evolution of the stellar-mass Tully-Fisher relation since z ~ 4

We use KMOS Deep Survey (KDS) galaxies, combined with results from a range of spectroscopic studies in the literature, to investigate the evolution of the stellar-mass Tully-Fisher relation since z ~ 4. We determine the slope and normalisation of the local rotation-velocity -- stellar-mass (Vc - $M_{\star}$) relationship using a reference sample of local spiral galaxies; thereafter we fix the slope, and focus on the evolution of velocity normalisation with redshift. The rotation-dominated KDS galaxies at z ~ 3.5 have rotation velocities ~ -0.1 dex lower than local reference galaxies at fixed stellar mass. By fitting 16 distant comparison samples spanning 0 1. We investigate the addition of pressure support, traced by intrinsic velocity dispersion ($\sigma_{int}$) to the KDS dynamical mass budget by adopting a 'total' effective velocity of form $V_{tot} = (Vc^{2} + 4.0\sigma_{int}^{2})^{0.5}$. The rotation-dominated and dispersion-dominated KDS galaxies fall on the same locus in the total-velocity versus stellar-mass plane, removing the need for debate over the precise selection threshold for rotation-dominated galaxies. The comparison sample offsets are in the range +0.08 to +0.15 dex in total-velocity zero-point (-0.30 to -0.55 dex in stellar-mass zero-point) from the local Tully-Fisher relation at z > 1, consistent with steady evolution of the ratio of dynamical to stellar mass with cosmic time.
Particle Production in Ultrarelativistic Heavy-Ion Collisions: A Statistical-Thermal Model Review

The current status of various thermal and statistical descriptions of particle production in the ultrarelativistic heavy-ion collisions experiments is presented in detail. We discuss the formulation of various types of thermal models of a hot and dense hadron gas (HG) and the methods incorporated in the implementing of the interactions between hadrons. It includes our new excluded-volume model which is thermodynamically consistent. The results of the above models together with the experimental results for various ratios of the produced hadrons are compared. We derive some new universal conditions emerging at the chemical freeze-out of HG fireball showing independence with respect to the energy as well as the structure of the nuclei used in the collision. Further, we calculate various transport properties of HG such as the ratio of shear viscosity-to-entropy using our thermal model and compare with the results of other models. We also show the rapidity as well as transverse mass spectra of various hadrons in the thermal HG model in order to outline the presence of flow in the fluid formed in the collision. The purpose of this review article is to organize and summarize the experimental data obtained in various experiments with heavy-ion collisions and then to examine and analyze them using thermal models so that a firm conclusion regarding the formation of quark-gluon plasma (QGP) can be obtained.
Regions of pollution with particulate matter in Poland

The study presents the temporal and spatial variability of particulate matter concentration in Poland in the calendar winter season (December-February). The basis for the study were the hourly and daily values of particulate matter PM10 concentration from the period 2005/06 – 2014/15, obtained from 33 air pollution monitoring stations. In Poland, the obligation to monitor the concentration of the finer fraction of particles smaller than 2.5µm in aerodynamic diameter was introduced only in 2010. Consequently, data on PM 2.5 concentration refer to a shorter period, i.e. 2009/10 – 2014/15, and were obtained from 23 stations. Using the cluster analysis (k-means method), three regions of comparable variability of particulate matter concentration were delineated. The largest region, i.e. Region I, comprises the northern and eastern central area of Poland, and its southern boundary is along the line Gorzow Wlkp-Bydgoszcz-Konin-Łodź-Kielce-Lublin. Markedly smaller Region II is located to the south of Region I. By far the smallest area was designated to Region III which covers the south west area of Poland. The delineated regions show a marked variability in terms of mean concentration of both PM fractions in winter (PM 10 : region I - 33 µg·m -3 , region II - 55 µg·m -3 , region III - 83 µg·m -3 ; PM 2,5 : region I - 35 µg·m -3 , region II - 50 µg·m -3 , region III - 60 µg·m -3 ) and, in the case of PM 10 , the frequency of excessive daily limit value.
Spin photocurrents in quantum wells

Spin photocurrents generated by homogeneous optical excitation with circularly polarized radiation in quantum wells (QWs) are reviewed. The absorption of circularly polarized light results in optical spin orientation due to the transfer of the angular momentum of photons to electrons of a two-dimensional electron gas. It is shown that in QWs belonging to one of the gyrotropic crystal classes a non-equilibrium spin polarization of uniformly distributed electrons causes a directed motion of electrons in the plane of the QW. A characteristic feature of this electric current, which occurs in unbiased samples, is that it reverses its direction upon changing the radiation helicity from left-handed to right-handed and vice versa. Two microscopic mechanisms are responsible for the occurrence of an electric current linked to a uniform spin polarization in a QW: the spin polarization-induced circular photogalvanic effect and the spin-galvanic effect. In both effects the current flow is driven by an asymmetric distribution of spin-polarized carriers in k-space of systems with lifted spin degeneracy due to k-linear terms in the Hamiltonian. Spin photocurrents provide methods to investigate spin relaxation and to reach a conclusion as regards the in-plane symmetry of QWs. The effect can also be utilized to develop fast detectors for determining the degree of circular polarization of a radiation beam. Furthermore, spin photocurrents under infrared excitation were used to demonstrate and investigate monopolar spin orientation of free carriers.
A Unified Model for Soil Shrinkage, Subsidence, and Cracking

Many clayey soils shrink as they dry, causing a shift of porosity from inside to outside the soil aggregates and leading to the formation of shrinkage cracks and/or surface subsidence. During swelling, shrinkage cracks begin to seal and/or the soil surface rises. Previous models have focused on describing shrinkage at the aggregate level, with little success in predicting soil cracking and subsidence. To remedy this shortcoming, we provide a unified, physically based set of governing equations for these three pore domains (aggregates, cracks, and subsidence) and predict the porosity distribution among domains as a function of soil water content and minimal (up to six) additional parameters. Examples collected from a variety of soils show how these functions describe shrinkage of soil samples in the laboratory; quantify the relationships among soil suction, soil shrinkage, and water content using the same set of parameters; and predict sealing of soil cracks in the field. This approach provides the framework for accurate and unified hydromechanical modeling of swelling soils.
