Parent and Student Perceptions of Parent Engagement at a Cyber Charter High School.

As enrollments in cyber charter schools grow, it becomes increasingly important to understand how parents engage in their students’ learning. Researchers have hypothesized that parental engagement is even more critical when online students learn from home, but few researchers have examined parents’ engagement behavior—especially parents of adolescent learners. In this case study we addressed this gap using parent and student interviews at a full-time online charter school. Our analysis of 19 interviews with 9 parents and 10 interviews with 10 students identified five primary types of parental engagement within this setting: (1) nurturing relationships and interactions, (2) advising and mentoring, (3) organizing, (4) monitoring and motivating student engagement, and (5) instructing. We also identified obstacles to effective parental engagement, and in this paper we discuss how programs can work with parents to foster more collaborative relationships.
Représentation et gestion de l'incertitude pour l'action

Nos entrees sensorielles, comme nos mouvements, sont entaches d’incertitudes. Pourtant, notre systeme nerveux central semble etre aussi precis que possible compte tenu de ces incertitudes: il les gere de maniere optimale, par exemple en ponderant des informations sensorielles redondantes en fonction de leur fiabilite, ou en prenant en compte ses incertitudes motrices lors de la realisation de mouvements. Si les modalites des combinaisons d’informations redondantes sont bien connues lors de tâches statiques, elles le sont moins en conditions dynamiques, lors de mouvements. La partie experimentale de cette these a permis de confirmer l’existence de mecanismes d’estimation et de controle optimaux des mouvements chez l’humain. En effet, nous avons mis en evidence l’integration optimale d’information visuelle lors de la realisation de saccades a la lumiere: lors de sequences de saccades, le systeme visuomoteur est capable d’utiliser l’information visuelle pour mettre a jour ses estimations internes de la position de l’œil. Une etude complementaire des sources de variabilite des saccades suggere un role similaire pour la proprioception extra-oculaire. Par une troisieme experience, novatrice, nous avons montre que le toucher est pris en compte en temps reel lors de mouvements de la main en contact avec une surface. Nous avons egalement infere une mesure de la variance de l'information tactile. Enfin, a partir des connaissances sur la representation des variables sensorimotrices dans le systeme nerveux, nous avons construit plusieurs reseaux de neurones qui implementent de maniere proche de l'optimum statistique la planification et le controle de mouvements
The last-mile logistical challenges of an omnichannel grocery retailer: A South African perspective

Background: The intense competition between grocery retailers to access new revenue streams has seen brick-and-mortar retailers broadening their services to offer consumers the option of ordering their groceries over the Internet. This is implemented through the implementation of different platforms such as their computer or mobile application − known as omnichannel retailing. Omnichannel grocery retailers are facing several challenges with the last mile of their online supply chain, especially with relation to the home delivery of groceries.Objectives: The purpose of the article was to gain an understanding of the nature of last-mile logistical challenges hindering the efficiency of an omnichannel grocery retailer in South Africa.Method: A qualitative methodology was employed; data were collected through an interview with the e-commerce operation manager of a well-known omnichannel grocery retailer in South Africa as well as through two focus group discussions conducted with consumers who regularly purchase items online and those who have never purchased any item online. Data were analysed using thematic analysis.Results: The findings suggested that there are four major last-mile logistical challenges facing the South African omnichannel grocery retailer considered in this study. The challenges are reliable order fulfilment, cold distribution chain requirements, physical distribution and reverse logistics.Conclusion: The findings of this article suggest that many of the last-mile challenges experienced by the omnichannel grocery retailer stem from the inefficient management of information (data) along the supply chain. To alleviate the last-mile logistical challenges identified in this article, emphasis should be placed on implementing a fully integrated information sharing system.
THE REFLECTIVE SUPERVISION MODEL: AN EFFORT TO INCREASE NURSE JOB SATISFACTION

Background: Job satisfaction influences the quality of health services in hospitals. However, low job satisfaction of nurses exists in the literature and influenced by various factors, including supervision. Thus, a reflective supervision model is considered effective in improving nurse job satisfaction. Objective: This study aims to analyze the effect of the reflective supervision model on nurse job satisfaction. Methods: This was a quasi-experimental study with control group design conducted between May-July 2017 in the Tugurejo Hospital and Dr. Moewardi hospital. There were sixty-eight nurses selected using purposive sampling, with 34 nurses assigned in the experiment and control group. Data were collected using questionnaires and then analyzed by paired t-test. Results: Paired t-test obtained p-value of 0.000, which indicated that the reflective supervision model has a significant influence to nurse work satisfaction. Conclusion: The reflective supervision model has a significant effect in increasing nurse job satisfaction. Therefore, this model could be applied by the head nurses to improve nurse outcome indicator, especially for nurse job satisfaction.
ALPHA-THALASSEMIA:DELETION ANALYSIS IN IRAN

Background-Alpha-thalassemia is one of the most prevalent hemoglobin disorders in the world. The molecular basis of α -thalassemia is deletions of variable lengths involving one or both α -genes at the α -globin gene cluster. Functional point mutations leading to inactivation of the α -genes are less frequent. So far, no comprehensive population screening for α -thalassemia has been performed in Iran and no molecular diagnostic services are available for this disease. As a result, a considerable number of patients with microcytic, hypochromic anemia and normal Hb A2 levels might be misdiagnosed as silent β-thalassemia. The aim of the present study was to determine the spectrum of common α thalassemia mutations in Iran. Methods-A total of 57 Iranian subjects were randomly chosen from a pool of patients with microcytic hypochromic anemia and negative β-thalassemia genotyping. They were tested for the 2 most frequent α -thalassemia deletions (-α 3.7, -α 4.2). Analysis was performed using deletion-specific PCR amplification followed by agarose gel electrophoresis of the resulting PCR fragments. Results- No -α 4.2 deletion was detected, however, 18 (31.6%) out of 57 analyzed cases demonstrated the -α 3.7 deletion, either in the homozygous or heterozygous state. Conclusion-This study suggests that the -α 3.7 deletion is a common cause of microcytic hypochromic anemia in Iran. The results are in accordance with previous studies, which report a remarkably high frequency of -α 3.7 in the Middle East. Routine screening for this mutation will improve the molecular diagnosis of anemia in Iran.
Recent interests on positron (e+ ), positronium (Ps) and antihydrogen (H)

A brief survey is made to highlight the recent interests in positron, positronium and antimatter physics. Positron is the first antiparticle observed which was predicted by Dirac. Positronium is itself its antiparticle and bi-positronium molecule is recently observed in laboratory which was predicted by Wheeler in 1946. The simplest antiatom i.e. antihydrogen is observed in the laboratory and the process to achieve the stable confinement of antihydrogen within the trap are in progress to test the standard model.
A numerical study of the effect of wetland shape and inlet-1 outlet configuration on wetland performance 2

Department of Industrial Engineering, University of Padua, via F. Marzolo 9, 35131 Padova, Italy, nima.sabokrouhiyeh@unipd.it, 4 andrea.marion@unipd.it, jevgenijs.savickis@studenti.unipd.it. 5 School of Mechanical, Aerospace and Civil Engineering, University of Manchester, Manchester, M13 9PL, UK, 6 andrea.bottacinbusolin@manchester.ac. uk 7 Department of Civil and Environmental Engineering, Massachusetts Institute of Technology, Cambridge, MA 02139, USA, 8 hmnepf@mit.edu. 9 10 Abstract. The hydraulic efficiency of wetlands for wastewater treatment was investigated as 11 a function of wetland shape and vegetation density using a 2D depth-averaged numerical 12 model. First, the numerical model was calibrated and validated against field data and then 13 was applied to 8 hypothetical wetlands of rectangular and elliptical shape and different aspect 14 ratio (i.e. 1:1 to 4:1). The vegetation density was varied from 0 to 1000 stems/m. The effect 15 of inlet-outlet configuration was analyzed by simulating the hydraulic response of wetlands 16 with different alignment of the flow inlet and outlet and wetlands with multiple inlets. The 17 resulting Residence Time Distributions (RTDs) were derived from numerical simulations of 18 the flow field and the temporal evolution of the outlet concentration of a passive tracer 19 injected at the inlet. The simulated velocity field demonstrated that wetland shape can have 20 significant impact on the size of dead zone areas, which is also reflected in the RTD. 21 Efficiency metrics associated with detention time and degree of mixing improved for an 22 elliptical shape compared to a rectangular shape. An ellipse shape improved the wetland 23 performance by reducing the area of dead zones at the corners, and thereby increasing the 24 effective wetland volume contributing to the treatment process. Configurations in which inlet 25 and outlet were located at opposite corners of the wetland, and wetlands with multiple inlets 26 produced smaller dead zones, which reduced the variance of the RTD. The simulation results 27 also revealed an interesting threshold behavior with regard to stem density. For stem density 28 above 300 stems/m, which is typical of treatment wetlands, the model predictions were not 29 sensitive to the exact value of stem density selected, which simplifies the parameterization of 30 models. This quantitative analysis of the effect of wetland shape, inlet-outlet configuration 31 and vegetation density can help engineers to achieve more efficient and cost-effective design 32 solutions for wastewater treatment wetlands. 33
Personality and Career - She’s Got What it Takes

The female share in management positions is quite low in Germany. The higher the hierarchical level, the fewer women there are in such positions. Men have numerous role models to follow whereas women lack this opportunity: In the executive boards of the top 200 private companies in Germany, only 2.5 percent of members are female. Many studies have focused on the influence of human capital and other "objective" factors on career opportunities. In our study, we go a step further by also looking at the impact of self-reported personality traits on gender differences in career chances. We compare managers and other white-collar employees in Germany's private sector. While bivariate results based on data from the German Socio-Economic Panel (SOEP) in 2005 show that there are significant gender differences in personality traits, multivariate estimations clearly indicate that these differences cannot account for gender differences in career opportunities. Nevertheless, personality traits might indeed play a role, albeit more indirectly: Some of the stronger career effects, such as work experience, long working hours, and labour market segregation, can also reflect differences in personality traits. These might have been influenced at an early stage by a gender-biased environment. Our results strongly stress the need for a gender-neutral environment outside and inside companies in order to enforce equal career opportunities for women and men.
A Didactic Reconstruction of the Financial and Economic Crisis

Theoretical approaches to constructivism have put learner autonomy into the spotlight of didactic discourse. Apart from the matter of pedagogic actions on how (constructivisticly) organised education might be arranged, this paper focuses on the perspective of didactic reconstruction. Thus, an observation-based research perspective is being adopted in this paper. The epistemic beliefs that have emerged over the course of the global financial and economic depression are reconstructed. The goal of the paper is to provide an insight into these different interpretations. In order to do this, university students were surveyed regarding this topic and the results of this qualitative study on these epistemic beliefs will be represented in this article. The paper tries to give answers on how students, who have been experiencing the financial and economic depression for nearly three years now, define its causes and what subsequent actions they would recommend. The results show that the main issue is not misinterpretation of political and economic knowledge but rather incomplete constructs based on only approximate knowledge.
Human Resources, Information Technology, and Performance of Public Health Institutions in Embu County, Kenya

The health sector plays a significant role in the economic development of a country by improving the livelihoods her citizens. Despite the heavy investment in the health sector by the Kenya government, enjoying the right to health has been a mere dream for many Kenyans across counties. The study sought to investigate the effect of human resources and information technology on performance of public health institutions in Embu County, Kenya. The study used explanatory and descriptive research designs and targeted 550 employees and 769 outpatients drawn from the five public hospitals in Embu County. The sample size comprised of 165 employees and 232 outpatients. Data was collected using semi-structured questionnaires and an interview guide. Quantitative data was analyzed using descriptive statistics and inferential statistics, while content analysis was used to analyse qualitative data. The findings of the study demonstrated that there was a positive and statistical significant effect of human resources and information technology on performance of public health institutions. Policy implications of study findings have been discussed. Keywords: strategic human resources, information technology, performance of public health institutions
SIGNATURES OF MAGNETIC RECONNECTION AT BOUNDARIES OF INTERPLANETARY SMALL-SCALE MAGNETIC FLUX ROPES

The interaction between interplanetary small-scale magnetic flux ropes and the magnetic field in the ambient solar wind is an important topic in the understanding of the evolution of magnetic structures in the heliosphere. Through a survey of 125 previously reported small flux ropes from 1995 to 2005, we find that 44 of them reveal clear signatures of Alfvénic fluctuations and thus classify them as Alfvén wave trains rather than flux ropes. Signatures of magnetic reconnection, generally including a plasma jet of ∼30 km s−1 within a magnetic field rotational region, are clearly present at boundaries of about 42% of the flux ropes and 14% of the wave trains. The reconnection exhausts are often observed to show a local increase in the proton temperature, density, and plasma beta. About 66% of the reconnection events at flux rope boundaries are associated with a magnetic field shear angle larger than 90° and 73% of them reveal a decrease of 20% or more in the magnetic field magnitude, suggesting a dominance of anti-parallel reconnection at flux rope boundaries. The occurrence rate of magnetic reconnection at flux rope boundaries through the years 1995–2005 is also investigated and we find that it is relatively low around the solar maximum and much higher when approaching solar minima. The average magnetic field depression and shear angle for reconnection events at flux rope boundaries also reveal a similar trend from 1995 to 2005. Our results demonstrate for the first time that boundaries of a substantial fraction of small-scale flux ropes have properties similar to those of magnetic clouds, in the sense that both of them exhibit signatures of magnetic reconnection. The observed reconnection signatures could be related either to the formation of small flux ropes or to the interaction between flux ropes and the interplanetary magnetic fields.
The Role Of Farm Size And Resource Constraints In The Choice Between Risky Technologies

This paper investigates the relationship between farm size and technology adoption by applying a model recently developed by Just and Zilberman to the choices of a sample of southwestern soybean farmers. The adoption of double cropping soybeans with wheat is evaluated with an expanded model which includes availability of specialized equipment and human capital. It is found that the empirical farm size-technology adoption relationship is consistent with risk aversion and a high covariance of returns between the old and new technologies. Accounting for human and physical capital differences across farms improves the power of the hypothesis tests.
Changes in the composition of the non-copepod zooplankton assemblage in St Helena Bay (southern Benguela ecosystem) during a six day drogue study

Marked changes in the composition and structure of the non-copepod components of a zooplankton assemblage were observed during the course of a 6 d drogue study in the southern Benguela ecosystem. These changes reflected in part the spiraled nature of the drogue and were linked to the settlement of meroplankton from the surface waters and to the nocturnal recruitment, and subsequent accumulation, of migratory holoplankton and zoobenthos from depth. The presence of large numbers of benthic species in the plankton is hypothesised to reflect their upward migration at night owing to food limitation, since little of the overlying diatom bloom was sedimenting out. The presence of low-oxygen bottom water is hypothesised to account for the failure of the detritivorous zoobenthos to return to the seafloor during the day. The results suggest that the composition of zooplankton assemblages in upwelling areas is not only driven by the dynamism of the physical environment, but that, under certain circumstances, a more subtle interplay between the biological and physical environment may result in strong changes in assemblage composition.
Evolutionary quantitative genetics of non-linear developmental 1 systems 2

9 In quantitative genetics, the effects of developmental relationships among traits on microevolu10 tion are generally represented by the contribution of pleiotropy to additive genetic covariances. 11 Pleiotropic additive genetic covariances arise only from the average effects of alleles on mul12 tiple traits, and therefore the evolutionary importance of non-linearities in development are 13 generally neglected in quantitative genetic views on evolution. However, non-linearities in rela14 tionships among traits at the level of whole organisms are undeniably important to biology in 15 general, and therefore critical to understanding evolution. I outline a system for characterising 16 key quantitative parameters in non-linear developmental systems, which yields expressions for 17 quantities such as trait means and phenotypic and genetic covariance matrices. I then develop 18 a system for quantitative prediction of evolution in non-linear developmental systems. I apply 19 the system to generating a new hypothesis for why direct stabilising selection is rarely observed. 20 Other uses will include separation of purely correlative from direct and indirect causal effects 21 in studying mechanisms of selection, generation of predictions of medium-term evolutionary 22 trajectories rather than immediate predictions of evolutionary change over single generation 23 time-steps, and the development of efficient and biologically-motivated models for separating 24 additive from epistatic genetic variances and covariances. 25 Morrissey, non-linear evolutionary quantitative genetics 3
AP1- and NF-κB-binding sites conserved among mammalian WNT10B orthologs elucidate the TNFα-WNT10B signaling loop implicated in carcinogenesis and adipogenesis

: WNT signals are context-dependently transduced to canonical and non-canonical signaling cascades. We cloned and characterized wild-type human WNT10B, while another group cloned aberrant human WNT10B with Gly60Asp amino-acid substitution. Proto-oncogene WNT10B is expressed in gastric cancer, pancreatic cancer, breast cancer, esophageal cancer, and cervical cancer. Because WNT10B blocks adipocyte differentiation, coding SNP of WNT10B gene is associated with familial obesity. In 2001, we reported WNT10B upregulation by TNFalpha. Here, comparative integromics analyses on WNT10B orthologs were performed to elucidate the transcriptional mechanism of WNT10B. Chimpanzee WNT10B and cow Wnt10b genes were identified within NW_001223159. 1 and AC150975.2 genome sequences, respectively, by using bioinformatics (Techint) and human intelligence (Humint). Chimpanzee WNT10B and cow Wnt10b showed 98.7% and 95.1% total-amino-acid identity with human WNT10B, respectively. N-terminal signal peptide, 24 Cys residues, two Asn-linked glycosylation sites, and Gly60 of human WNT10B were conserved among mammalian WNT10B orthologs. Transcription start site of human WNT10B gene was 106-bp upstream of NM_003394. 2 RefSeq 5'-end. Number of GC di-nucleotide repeats just down-stream of WNT10B transcription start site varied among primates and human population. Comparative genomics analyses revealed that double AP1-binding sites in the 5'-flanking promoter region and NF-kappaB-binding site in intron 3 were conserved among human, chimpanzee, cow, mouse, and rat WNT10B orthologs. Because TNFalpha signaling through TNFR1 and TRADD/RIP/TRAF2 complex activates JUN kinase (JNK) and IkappaB kinase (IKK) signaling cascades, conserved AP1- and NF-kappaB-binding sites explain the mechanism of TNFalpha-induced WNT10B upregulation. TNFalpha-WNT10B signaling loop is the negative feedback mechanism of adipogenesis to prevent obesity and metabolic syndrome. On the other hand, TNFalpha-WNT10B signaling loop is implicated in carcinogenesis. Inhibitors of TNFalpha-WNT10B signaling loop could be utilized for the prevention or treatment of cancer associated with chronic inflammation, such as gastric, liver, breast and pancreatic cancer.

LONG TERM MORPHOLOGICAL MODELLING

A morphological modelling concept for long term nearshore morphology is proposed and examples of its application are presented and discussed. The model concept combines parameterised representations of the cross-shore morphology, with a 2DH area model for waves, currents and sediment transport in the surf zone. Two parameterization schemes are tested for two different morphological phenomena: 1) Shoreline changes due to the presence of coastal structures and 2) alongshore migration of a nearshore nourishment and a bar by-passing a harbour. In the case of the shoreline evolution calculations, a concept often used in one-line modelling of cross-shore shifting of an otherwise constant shape cross-shore profile is applied for the case of a groyne and a detached breakwater. In the case of alongshore bar/nourishment migration an alternative parameterization is adopted. All examples are presented, analysed and discussed with respect to the question of realistic representation, time scale and general applicability of the model concept.
