Point-of-Admission Serum Electrolyte Profile of Children less than Five Years Old with Dehydration due to Acute Diarrhoea

Background/Objective: Fluid, electrolytes and acid base disturbances are responsible for most deaths due to acute diarrhoea. The aim of this study is to describe the point-of-admission serum electrolyte profile of children with dehydration due to acute diarrhoea. Methods: In this cross-sectional study, the serum electrolyte levels of 185 children with dehydration due to acute diarrhoea were assessed at the point of admission at the Diarrhoea Treatment and Training Unit of the University of Benin Teaching Hospital. The age of the study population ranged from 29 days to 59 months. Results: Out of a total of 185 subjects, 30 (16.2%), 114 (61.6%), and 41 (22.2%) had severe, moderate and mild dehydration, respectively. In addition, hyponatraemic dehydration was the most common type of dehydration, accounting for 60.5% of cases. Metabolic acidosis and hypokalaemia occurred in 59.5% and 44.3% of cases, respectively. Only the serum bicarbonate level was significantly affected by degree of dehydration (p = 0.001). Age of more than 12 months and presence of vomiting were significantly associated with hyponatraemia (p = 0.005 & p = 0.02), while age of less than or equal 12 months and absence of vomiting were associated with metabolic acidosis (p = 0.04 & p = 0.03). Conclusion: The degree of dehydration appears to be a good predictor of the occurrence of metabolic acidosis while age is a risk factor for hyponatraemia and metabolic acidosis.
Portable Option Discovery for Automated Learning Transfer in Object-Oriented Markov Decision Processes

We introduce a novel framework for option discovery and learning transfer in complex domains that are represented as object-oriented Markov decision processes (OO-MDPs) [Diuk et al., 2008]. Our framework, Portable Option Discovery (POD), extends existing option discovery methods, and enables transfer across related but different domains by providing an unsupervised method for finding a mapping between object-oriented domains with different state spaces. The framework also includes heuristic approaches for increasing the efficiency of the mapping process. We present the results of applying POD to Pickett and Barto's [2002] Policy-Blocks and MacGlashan's [2013] Option-Based Policy Transfer in two application domains. We show that our approach can discover options effectively, transfer options among different domains, and improve learning performance with low computational overhead.
K-12 Teacher Perceptions Regarding the Flipped Classroom Model for Teaching and Learning

A great deal of evidence can be cited from higher education literature on the effectiveness of the flipped classroom; however, very little research was discovered on the flipped classroom at the K-12 level. This study examined K-12 teachers’ perceptions regarding the flipped classroom and differences in teachers’ perceptions based on grade level and content area taught. A researcher-developed survey instrument was used to collect data from K-12 teachers that utilize a flipped classroom in Southwest and South Central Minnesota. Survey participants totaled 44, which included 27 high school teachers, 15 middle school teachers, and 2 teachers that identified as other. It was found that participants perceived that the flipped classroom creates time for varied instructional techniques, including active learning and higher order thinking, along with increased student-to-teacher interaction. The insights from the study inform teachers in the field about benefits and best practices in regard to the flipped classroom instructional model.
Fractional frequency reuse-based resource sharing strategy in two-tier femtocell networks

In this paper, we propose a downlink resource sharing strategy in two-tier networks with the co-channel femtocell deployment. The proposed resource sharing strategy adopts the fractional frequency reuse (FFR) framework to maximize the spectral efficiency and overcome the femto-to-macro interference (FMI) problem at the same time. In the proposed strategy, resource units in each frequency partition (FP) are divided into a macro-privileged group and a femto-dedicated group. To protect the macrocell from the FMI, the resource usage of the femtocells is controlled according to the FP assignments of the nearby macrocell users. In addition, the per-FP resource division is determined to maximize the spectral efficiency while balancing macrocell/femtocell user throughputs. Simulation results show that the proposed resource sharing strategy can achieve high spectral efficiency while suppressing the FMI effectively.
1 0 O ct 2 00 2 A new integrable hierarchy , parametric solution and traveling wave solution

This paper gives a new integrable hierarchy of nonlinear evolution equations. In this hierarchy there are the following representative equations: ut = ∂ 5 xu − 2 3 , ut = ∂ 5 x (u 1 3 )xx − 2(u 1 6 )x u ; uxxt + 3uxxux + uxxxu = 0. The first two are in the positive order hierarchy while the 3rd one is in the negative order hierarchy. The whole hierarchy is shown integrable through solving a key 3×3 matrix equation. The 3×3 Lax pairs and their adjoint representations are nonlinearized to be two Liouvilleintegrable canonical Hamiltonian systems. Based on the integrability of 6N -dimensional systems we give the parametric solution of the positive hierarchy. In particular, we obtain the parametric solution of the equation ut = ∂ 5 xu − 2 3 . Finally, we give the traveling wave solution (TWS) of the above three equations. The TWSs of the first two equations have singularity, but the TWS of the 3rd one is continuous. For the 5th-order equation, its smooth parametric solution can not include its singular TWS. We also analyse the initial Gaussian solutions for the equations ut = ∂ 5 xu − 2 3 , and uxxt + 3uxxux + uxxxu = 0. Both of them are stable.
‘I just find it boring’: Findings from an affective adolescent reading intervention

Research suggests that reading engagement and motivation are strong predictors of reading performance. Reading motivation may decline as students approach adolescence, resulting in less time spent with text. To date, there has been no research on how practitioners might directly support students to address affective factors in reading. In this exploratory case study, three disengaged, Year 8 readers received five sessions of an affective intervention aimed at helping them explore and challenge their own ambivalence towards reading. Quantitative and qualitative data from pre-, post- and three-month follow-up indicated a range of benefits in relation to reading engagement and motivation, including improved self-efficacy, increased participation and the usefulness of talking about affective factors in reading. Findings are further examined and implications for practitioners are discussed. [ABSTRACT FROM AUTHOR]
HUBUNGAN HARGA DIRI DENGAN PERILAKU KONSUMTIF REMAJA DI BANDA ACEH

Some adolescence among at Banda Aceh could not to accept their physical self either excess or a deficiency in themself so that the adolescence doing the imitating behavior others people as a model (the idol) with consumptive behavior a manner in order to change the appearance for the sake of to cover their a deficiency. This objective research is to know the relationship between self esteem and consumptive behavior on adolescence at Banda Aceh and the hypothesis presented in this objective research are there is a negative relationship between self esteem and consumptive behavior on adolescence at Banda Aceh. The sample in this objective research involving 84 adolescence and sampling design by using simple random sampling. Data collected by using psychology scales is Self Esteem Scales compiled with reference to the Coopersmith theory (1967) and Consumptive Behavior Scales compiled with reference to the Sumartono theory (2002). Data to analys by using Product Moment correlation technique with correlation coefisient (r) was -0,324 and significant value (p) was 0,003 (p<0,01). The result showed that there is a negative relationship significantly between self esteem and consumptive behavior, it means the more higher self esteem for adolescence Banda Aceh, then the more lower consumptive behavior, Instead the more lower self esteem for adolecence Banda Aceh, then the more higher consumptive behavior for the student/girl student.
The Social Contagion of Generosity

Why do people help strangers when there is a low probability that help will be directly reciprocated or socially rewarded? A possible explanation is that these acts are contagious: those who receive or observe help from a stranger become more likely to help others. We test two mechanisms for the social contagion of generosity among strangers: generalized reciprocity (a recipient of generosity is more likely to pay it forward) and third-party influence (an observer of generous behavior is more likely to emulate it). We use an online experiment with randomized trials to test the two hypothesized mechanisms and their interaction by manipulating the extent to which participants receive and observe help. Results show that receiving help can increase the willingness to be generous towards others, but observing help can have the opposite effect, especially among those who have not received help. These results suggest that observing widespread generosity may attenuate the belief that one’s own efforts are needed.
Signal region characterization and exact phase recovery for constant envelope precoding in single-user large-scale MISO channels

This paper considers constant envelope (CE) precoding in single-user MISO downlink systems. CE precoding is a transmission scheme recently proposed for very large antenna arrays, in which the use of highly power-efficient RF amplifiers is a requirement. There are two important issues in CE precoding, namely the characterization of the region of all possible noise-free receive signals, and the recovery of the phases of the transmitting signal. An existing result by Mohammed and Larsson showed that the noise-free receive signal region can be geometrically interpreted as a region between two circles centered at the origin of the complex plane. However, this result did not prove the expression of the radius of the inner circle. We provide a new analysis approach to characterize the noise-free receive signal region. Our result shows that the radius of the inner circle has a simple closed-form expression, there by completing the result by Mohammed and Larsson. In addition, we propose an algorithm that can recover the phases of the transmitting signal exactly with a complexity linear in the number of antennas. Simulation results show that the proposed method can be significantly faster than an existing phase recovery algorithm.
A global perspective on disparity of gender and disability for deaf female athletes

Abstract Although the significance of gender and disability issues has gradually increased in the global society during the past three decades, there are only few studies with regard to the deaf community and sport. This article examines the level of Deaf or Hard-of-Hearing women’s participation in sports and the factors for their continued underrepresentation. The WomenSport International’s Task Force on Deaf and Hard of Hearing Girls and Women in Sport conducted a world-wide survey to determine and assess the needs of deaf and hard of hearing girls and women in sport. A snapshot of the results and issues and future aspirations are provided.
Intra- and inter-chip voltage droop analysis using a power delivery grid model

Connection of power supply for chips and cores is a complex model. Due to both the physical structure of the silicon and the temporal workload, significant voltage variation can be observed at the power grid. Especially, voltage droop can be severe and causes problems, such as signal propagation delay or even faults. Thorough understanding about the cause of voltage droop may give a more reliable prediction on how the power supply varied so the power can be utilized effectively. In this paper, an intra- and inter-chip power delivery model is developed and is used for analyzing the voltage droop with different cores and tasks scheduled. This multi-chip power grid model is an extension from the single chip model and is capable for integrating intra- and interchip networks. To verify the design, we can simulate the synthetic current workloads using SPICE. Based on this model, we can outline that the voltage droop, which can be reduced significantly when the tasks are scheduled with spatial and temporal changes.
RISK MANAGEMENT AND INFORMATION TECHNOLOGY PROJECTS

IT projects management is not free from risks which are created from various sources of the environment. Thus a comprehensive understanding of these possible risks and creating strategic policies to confront them are one of the fundamental requirements for successful implementation of IT projects. The risks faced during the implementation of IT Projects are not just related to financial aspects. IT Project Managers must embrace these fundamental issues with more holistic view, rather than merely focusing on the financial matters. In order to prevent the potential problems from arising or escalating into bigger magnitude, serious attention must be given to it before the implementation of any IT project. The main focus of this paper is to investigate the impacts of Knowledge Management (KM) on Risk Management (RM) in IT project implementation process.
A framework for testing safety and effective computability of extended datalog

This paper presents a methodology for testing a general logic program containing function symbols and built-in predicates for safety and effective computability. Safety is the property that the set of answers for a given query is finite. A related issues is whether the evaluation strategy can effectively compute all answers and terminate. We consider these problems under the assumption that queries are evaluated using a bottom-up fixpoint computation. We also approximate the use of function symbols by considering Datalog programs with infinite base relations over which finiteness constraints and monotonicity constraints are considered. One of the main results of this paper is a recursive algorithm, check_clique, to test the safety and effective computability of predicates in arbitrarily complex cliques. This algorithm takes certain procedures as parameters, and its applicability can be strengthened by making these procedures more sophisticated. We specify the properties required of these procedures precisely, and present a formal proof of correctness for algorithm check_clique. This work provides a framework for testing safety and effective computability of recursive programs, and is based on a clique by clique analysis. The results reported here form the basis of the safety testing for the LDL language, being implemented at MCC.
Querying Streaming XML Big Data with Multiple Filters on Cloud

Nowadays, we enter a new era of data explosion which introduces the new problems for big data processing. Current methods for querying streaming XML big data are mostly based on events filtering techniques. It is well known that during the filtering, some data items have to be buffered before the filter can make the proper decision for adopting strategies to deal with them. Furthermore, for a single filter system, the buffer size often increases exponentially in the real application. Cloud is an ideal platform for big XML data processing with its massive storage and powerful computation capability. In this paper, we propose a new multi-filters strategy for querying streaming XML big data on Cloud. We show that the proposed multi-filters strategy can effectively share and reduce the filtering space and time consumption by fully exploit the scalability of Cloud. Furthermore, by deploying our multi-filters collaboration technique, the querying systems together can break the limitation of the theoretic concurrency lower bound. The empirical study shown in this paper demonstrates that our multi-filters strategy outperforms the single filter querying significantly.
MO-ABC/DE - Multiobjective Artificial Bee Colony with Differential Evolution for unconstrained multiobjective optimization

Multiobjective optimization (MO) is attracting much attention of researchers in the last years. This is because most of the currently addressed optimization problems need to optimize multiple conflicting objective functions simultaneously. In this work, we propose a new algorithm called Multiobjective Artificial Bee Colony with Differential Evolution (MO-ABC/DE) for solving a set of unconstrained multiobjective optimization problems. The MO-ABC/DE algorithm is a new hybrid approach that combines the collective intelligence of the honey bee swarms (Artificial Bee Colony - ABC) with the properties of the Differential Evolution (DE). To analyse the performance of our metaheuristics we solve ten unconstrained multiobjective problems defined for the CEC 2009 Special Session on “Performance Assessment of Constrained / Bound Constrained Multiobjective Optimization Algorithms”. These test problems optimize two or three objective functions and present different properties of separability, modality, and geometry in their Pareto fronts. As we will see, the MO-ABC/DE algorithm works well on most test problems, proving to be an important tool to solve multiobjective unconstrained optimization problems.
High-Resolution Mapping of H1 Linker Histone Variants in Embryonic Stem Cells

H1 linker histones facilitate higher-order chromatin folding and are essential for mammalian development. To achieve high-resolution mapping of H1 variants H1d and H1c in embryonic stem cells (ESCs), we have established a knock-in system and shown that the N-terminally tagged H1 proteins are functionally interchangeable to their endogenous counterparts in vivo. H1d and H1c are depleted from GC- and gene-rich regions and active promoters, inversely correlated with H3K4me3, but positively correlated with H3K9me3 and associated with characteristic sequence features. Surprisingly, both H1d and H1c are significantly enriched at major satellites, which display increased nucleosome spacing compared with bulk chromatin. While also depleted at active promoters and enriched at major satellites, overexpressed H10 displays differential binding patterns in specific repetitive sequences compared with H1d and H1c. Depletion of H1c, H1d, and H1e causes pericentric chromocenter clustering and de-repression of major satellites. These results integrate the localization of an understudied type of chromatin proteins, namely the H1 variants, into the epigenome map of mouse ESCs, and we identify significant changes at pericentric heterochromatin upon depletion of this epigenetic mark.
Reaching out or missing out: approaches to outreach with family carers in social care organisations

Outreach is advocated as a way of improving the uptake of services among underserved populations and of filling the gaps between mainstream services and the populations they are intended to support. Despite the policy emphasis on providing better help for family carers, research consistently shows that many of those providing unpaid care to a family member or friend report difficulties in finding out about the assistance to which they are entitled. This article presents results from a concurrent mixed-methods study, which aimed to describe different ways of working with family carers in adult social care departments and to collect the views of a range of stakeholders about the advantages and disadvantages of the approaches that were identified. A total of 86 semi-structured face-to-face interviews were undertaken with a purposive sample of funders, carers' workers, representatives of voluntary organisations and family carers based in four contrasting localities. An email survey was sent to all local councils in England with social care responsibilities and resulted in a 53% response rate. Data collection took place in 2012, with a small number of interviews being completed in 2011. Our approach to data analysis combined methodological, data and theoretical triangulation. The findings presented here mainly draw on the interview data to highlight the different models of outreach that we identified. The article highlights important differences between outreach and the provision of information. It concludes that organisations providing support for carers need to consider the advantages and disadvantages of different models of outreach as they develop carers' support and the extent to which different models might be more effective than others in reaching particular types of carer.
Novel Oligoamine Analogues Inhibit Lysine-Specific Demethylase 1 and Induce Reexpression of Epigenetically Silenced Genes

Purpose: Abnormal DNA CpG island hypermethylation and transcriptionally repressive histone modifications are associated with the aberrant silencing of tumor suppressor genes. Lysine methylation is a dynamic, enzymatically controlled process. Lysine-specific demethylase 1 (LSD1) has recently been identified as a histone lysine demethylase. LSD1 specifically catalyzes demethylation of mono– and dimethyl–lysine 4 of histone 3 (H3K4), key positive chromatin marks associated with transcriptional activation. We hypothesized that a novel class of oligoamine analogues would effectively inhibit LSD1 and thus cause the reexpression of aberrantly silenced genes. Experimental Design: Human colorectal cancer cells were treated with the oligoamines and changes in mono- and dimethyl-H3K4 and other chromatin marks were monitored. In addition, treated cells were evaluated for the reexpression of the aberrantly silenced secreted frizzled-related proteins (SFRP) Wnt signaling pathway antagonist genes. Finally, the effects of the LSD1 inhibitors were evaluated in an in vivo xenograft model. Results: Treatment of HCT116 human colon adenocarcinoma cells in vitro resulted in increased H3K4 methylation and reexpression of silenced SFRP genes. This reexpression is also accompanied by a decrease in H3K9me2 repressive mark. Importantly, cotreatment with low doses of oligoamines and a DNA methyltransferase inhibitor highly induces the reexpression of the aberrantly silenced SFRP2 gene and results in significant inhibition of the growth of established tumors in a human colon tumor model in vivo. Conclusions: The use of LSD1-inhibiting oligoamine analogues in combination with DNA methyltransferase inhibitors represents a highly promising and novel approach for epigenetic therapy of cancer.
