Evolving Clinical Strategies for Transplantation in the HIV-Positive Recipient

The transplant community has been slow to recognize the efficacy of highly active antiretroviral therapy in changing the course of human immunodeficiency virus (HIV) infection to a chronic condition. People infected with HIV are dying less often from progression of HIV to acquired immune deficiency syndrome. Unfortunately, there is an increasing rate of morbidity and mortality from comorbidities resulting in end-stage liver and kidney disease, prompting some transplant centers to eliminate HIV infection as a contraindication to transplantation. This overview will describe the evolving clinical strategies that have resulted in good outcomes after solid organ transplantation in the HIV-positive recipient.
Sentence Ordering based on Cluster Adjacency in Multi-Document Summarization

In this paper, we propose a cluster-adjacency based method to order sentences for multi-document summarization tasks. Given a group of sentences to be organized into a summary, each sentence was mapped to a theme in source documents by a semi-supervised classification method, and adjacency of pairs of sentences is learned from source documents based on adjacency of clusters they belong to. Then the ordering of the summary sentences can be derived with the first sentence determined. Experiments and evaluations on DUC04 data show that this method gets better performance than other existing sentence ordering methods.
A query based graph-oriented load-shedding for RDF stream processing

To cope with heterogeneity of data in streams, Semantic Web technologies (RDFVSPARQL2) have recently been used for annotation, publication and reasoning on these data. To deal with this new kind of streams, researchers have proposed new systems named RDF Stream Processing (RSP). Unfortunately, in limited system resources environment, these systems are fallible as soon as their maximum supported speed is reached. To overcome these problems, some efforts have been done in this area. Most of them, based on a triple-oriented approach and according to a probabilistic method, decrease the volume of RDF data stream using load-shedding techniques. In this paper we propose an enhancement of a Graph-Oriented approach for load-shedding semantic data streams, by considering the continuous query as input. Conducted experiments show that we can keep the RSP's recall at 100% even if we drop more than half of data.
Unraveling bed slope from relative roughness in initial sediment motion

Understanding incipient sediment transport is crucial for predicting landscape evolution, mitigating flood hazards, and restoring riverine habitats. Observations show that the critical Shields stress increases with increasing channel bed slope, and proposed explanations for this counterintuitive finding include enhanced form drag from bed forms, particle interlocking across the channel width, and large bed sediment relative to flow depth (relative roughness). Here we use scaled flume experiments with variable channel widths, bed slopes, and particle densities to separate these effects which otherwise covary in natural streams. The critical Shields stress increased with bed slope for both natural gravel (ρs = 2.65 g/cm3) and acrylic particles (ρs = 1.15 g/cm3), and adjusting channel width had no significant effect. However, the lighter acrylic particles required a threefold higher critical Shields stress for mobilization relative to the natural gravel at a fixed slope, which is unexpected because particle density is accounted for directly in the definition of Shields stress. A comparison with model predictions indicates that changes in local velocity and turbulence associated with increasing relative roughness for lighter materials are responsible for increasing the critical Shields stress in our experiments. These changes lead to concurrent changes in the hydraulic resistance and a nearly constant critical stream power value at initial motion. Increased relative roughness can explain much of the observed heightened critical Shields stresses and reduced sediment transport rates in steep channels and also may bias paleohydraulic reconstructions in environments with exotic submerged densities such as iron ore, pumice, or ice clasts on Titan.
Can We Increase Psychological Well-Being? The Effects of Interventions on Psychological Well-Being: A Meta-Analysis of Randomized Controlled Trials

Background There is a rapidly growing interest in psychological well-being (PWB) as outcome of interventions. Ryff developed theory-based indicators of PWB that are consistent with a eudaimonic perspective of happiness. Numerous interventions have been developed with the aim to increase PWB. However, the effects on PWB measured as coherent outcome have not been examined across studies yet. This meta-analysis of randomized controlled trials of behavioral interventions aims to answer the question whether it is possible to enhance PWB. Methods A systematic literature search was performed in PsycINFO, Cochrane and Web of Science. To be included, studies had to be randomized controlled trials of behavioral interventions with psychological well-being as primary or secondary outcome measure, measured with either Ryff’s Psychological Well-Being Scales or the Mental Health Continuum—Short Form. The meta-analysis was performed using a random effects model. From the 2,298 articles found, 27 met the inclusion criteria. The included studies involved 3,579 participants. Results We found a moderate effect (Cohen’s d = 0.44; z = 5.62; p < .001). Heterogeneity between the studies was large (Q (26) = 134.12; p < . 001; I2 = 80.62). At follow-up after two to ten months, a small but still significant effect size of 0.22 was found. There was no clear indication of publication bias. Interventions were more effective in clinical groups and when they were delivered individually. Effects were larger in studies of lower quality. Conclusions It appears to be possible to improve PWB with behavioral interventions. The results are promising for the further development and implementation of interventions to promote PWB. Delivering interventions face-to-face seems to be the most promising option. We recommend to keep including clinical groups in the research of psychological well-being. Heterogeneity is a limitation of the study and there is need for more high-quality studies.
A Zero Structure Theorem for Differential Parametric Systems

Abstract We present a zero structure theorem for a differential parametric system: p1 = 0,…,pr = 0, d1 ≠ 0,…,d3 ≠ 0 where pi and di are differential polynomials in K{u1,…, um, x1 ,…, xn} and the u are parameters. According to this theorem we can identify all parametric values for which the parametric system has solutions for the xi and at the same time giving the solutions for the xi in an explicit way, i.e., the solutions are given by differential polynomial sets in triangular form. In the algebraic case, i.e. when pi and di are polynomials, we present a refined algorithm with higher efficiency. As an application of the zero structure theorem presented in this paper, we give a new algorithm of quantifier elimination over differential algebraic closed fields. The algorithm has been implemented and several examples reported in this paper show that the algorithm is of practical value.
Where You Work Matters : Student Affairs Administration at Different Types of Institutions

This volume challenges the widely held assumption that the professional practice of student affairs administration transcends the influence of organizational culture. Based on data and commentaries from more than 1,100 practitioners, this book describes how the experience of student affairs administrators varies by institutional type. The findings paint a multifaceted and integrated portrait of the profession.
Processor scheduling in shared memory multiprocessors

Existing work indicates that the commonly used “single queue of runnable tasks” approach to scheduling shared memory multiprocessors can perform very poorly in a multiprogrammed parallel processing environment. A more promising approach is the class of “two-level schedulers” in which the operating system deals solely with allocating processors to jobs while the individual jobs themselves perform task dispatching on those processors. In this paper we compare two basic varieties of two-level schedulers. Those of the first type, static, make a single decision per job regarding the number of processors to allocate to it. Once the job has received its allocation, it is guaranteed to have exactly that number of processors available to it whenever it is active. The other class of two-level scheduler, dynamic, allows each job to acquire and release processors during its execution. By responding to the varying parallelism of the jobs, the dynamic scheduler promises higher processor utilizations at the cost of potentially greater scheduling overhead and more complicated application level task control policies. Our results, obtained via simulation, highlight the tradeoffs between the static and dynamic approaches. We investigate how the choice of policy is affected by the cost of switching a processor from one job to another. We show that for a wide range of plausible overhead values, dynamic scheduling is superior to static scheduling. Within the class of static schedulers, we show that, in most cases, a simple “run to completion” scheme is preferable to a round-robin approach. Finally, we investigate different techniques for tuning the allocation decisions required by the dynamic policies and quantify their effects on performance. We believe our results are directly applicable to many existing shared memory parallel computers, which for the most part currently employ a simple “single queue of tasks” extension of basic sequential machine schedulers. We plan to validate our results in future work through implementation and experimentation on such a system.
Homological algebra of homotopy algebras

We define closed model category structures on different categories connected to the world of operad algebras over the category C(k) of (unbounded) complexes of k-modules: on the category of operads, on the category of algebras over a fixed operad, on the category of modules over a fixed operad algebra. In Sections 2 - 6 we define the necessary structures and provide some standard comparison results. In Section 7 we define cotangent complex. In Section 8 we define a canonical structure of homotopy Lie algebra on the tangent complex.
Recombinant LH supplementation during IVF cycles with a GnRH-antagonist in estimated poor responders: A cross-matched pilot investigation of the optimal daily dose and timing

Although it is widely accepted that patients, who are considered poor responders to in vitro fertilization (IVF) benefit from recombinant luteinizing hormone (rLH) supplementation during an in vitro fertilization cycle, particularly when gonadotropin-releasing hormone (GnRH) antagonist (ant) treatment is used the optimal administration timing and daily dose of rLH remains to be elucidated. The aim of the present study was to investigate the optimal timing of rLH-supplementation to improve ovarian response, embryo quality, endometrial thickness and pregnancy rate in infertile, estimated poor responders to IVF, undergoing GnRH-ant treatment. In addition, the present study aimed to evaluate the optimal daily dose to achieve the same outcomes. A prospective-randomized-cross-matched investigation was performed on 40 patients undergoing a GnRH-ant-treatment-cycle The patients were randomly assigned to either group A (rLH-75 IU/day) or group B (rLH-150 IU/day) and further randomized into subgroup A1/B1, in which rLH was administered at recombinant follicle stimulating hormone (rFSH) administration, and subgroup A2/B2, in which rLH was administered at GnRH-ant administration. Patients who did not become pregnant during the first cycle (35 patients), were treated a second time, cross-matched for groups and subgroups. Improved ovarian response, embryo quality and pregnancy rate were achieved by administering rLH at 150 IU/day, starting from GnRH-ant administration, independently from the total rLH dose administered. Improved endometrial thickness at oocyte retrieval day was achieved by administering rLH at 150 IU from the start of rFSH administration. These data led to the hypothesis that ovarian responses are affected by the timing of administration more than the total-dose of rLH. The optimal window to administer rLH appears to be the mid-to-late follicular phase, despite the fact that rLH-supplementation in the early follicular phase appeared to increase endometrial thickness and to enhance its morphology. Standardization of the optimal daily dose and supplementation timing of rLH may resolve the debate regarding its efficacy in increasing the number of pregnancies and neonatal survival rates.
On examining the role of English education knowledge structures in pedagogic practices : case study of English educators in a higher education institution.

This study examines how English Education knowledge structures impact on pedagogy to serve students who are becoming English educators. The study investigates the English Education discipline within the School of Education, University of KwaZulu – Natal. The study responds to the critical question: how do English Education knowledge structures impact on pedagogy to serve students who are becoming English educators? This question seeks to uncover underlying structures, mechanisms and events at play in the English Education discipline, and how these inform knowledge structures to impact on pedagogy the way they do. The study is located on an interpretive research paradigm, and is framed within the Critical Realism (Bhaskar, 1978) and Social Realism (Archer, 1995) theories. These theories are used to critically engage with data by uncovering the underlying structures and mechanisms at play in the English Education discipline. The study further draws on Bernstein (1999) and Bourdieu (1986) as substantive theories used to develop a profound understanding of Knowledge Structures and Cultural Capital, respectively. Using qualitative methods of data collection, the study uncovers the role of a 2-Track System in the teaching of English Education students. Data collected in the study is analysed and critiqued to demonstrate how and why the structuring of English Education knowledge breaks away from unintended curricular impositions by the former University of Natal English Department’s curriculum. The study argues that the 2-Track System adopted in the English Education discipline is appropriate to serve students to be competent educators of English. Of paramount importance, data collected in the study also show how the structuring of English Education knowledge in the 2-Track System empowers and ‘give voice to’ the majority (Bernstein,
Security Evaluation for Information Assurance

In general, threat agents' primary goals may fall into three categories: unauthorized access, unauthorized modification or destruction of important information assets, and denial of authorized access. Security countermeasures are implemented to prevent threat agents from successfully achieving these goals. Because the general systems of today are composed of a number of components such as servers and clients, protocols, services, and so on, the possibility of success of attack may be increased. As though Systems connected to network have become more complex and wide, unfortunately, the researches for the systems are focused on the 'performance' or 'efficiency'. While most of the attention in system security has been focused on encryption technology and protocols for securing the data transaction, it is critical to note that a weakness (or security hole) in any one of the components may comprise whole system. Security engineering is needed for reducing security holes may be included in the Information systems. This paper proposes a method for securing the Information systems by evaluation of security functions of system component. This paper proposes Information system security evaluation and certification for achieving some level of assurance each owners of their Information systems want to get.
Phenotypic and genomic differentiation of Arabidopsis thaliana along altitudinal gradients in the North Italian alps

Altitudinal gradients represent short-range clines of environmental parameters like temperature, radiation, seasonality and pathogen abundance, which allows to study the foot-prints of natural selection in geographically close populations. We investigated phenotypic variation for frost resistance and light response in five Arabidopsis thaliana populations ranging from 580 to 2,350 meters altitude at two different valleys in the North Italian Alps. All populations were resequenced as pools and we used a Bayesian method to detect correlations between allele frequencies and altitude while accounting for sampling, pooled sequencing and the expected amount of shared drift among populations. The among population variation to frost resistance was not correlated with altitude. An anthocyanin deficiency causing a high leaf mortality was present in the highest population, which may be non-adaptive and potentially deleterious phenotypic variation. The genomic analysis revealed that the two high-altitude populations are more closely related than the geographically close low-altitude populations. A correlation of genetic variation with altitude revealed an enrichment of highly differentiated SNPs located in genes that are associated with biological processes like response to stress and light. We further identified regions with long blocks of presence absence variation suggesting a sweep-like pattern across populations. Our analysis indicate a complex interplay of local adaptation and a demographic history that was influenced by glaciation cycles and/or rapid seed dispersal by animals or other forces.

Problems and Solutions of DHCP-Experiences with DHCP implementation and Operation-Akihiro Tominaga

An implementation of DHCP (called WIDE version) has been made and beta-tested in some practical uses since March 1994. WIDE version DHCP achieves full semantical compatibilities with the exisiting UNIX system architecture, the architectural independency, the administration e ciency on the UNIX environment, and the interoperability with BOOTP-based clients and other DHCP implementations. As the results of the experiences, several problems of DHCP have been found: a) The DHCP client is unable to perform a veri cation simultaneously with a lease extension. b) A design di culty was claimed since the usage of a DHCP message is too complicated. c) There is no acknowledgement mechanism for releasing addresses. d) A concentration of address reuse requests were detected under some circumstances. These problems have been solved by modifying DHCP speci cations. Other problems have also been found such as ; a) lack of fault-torelancy in DHCP, b) no active noti cation from server to client, and c) no mechanism to retrieve addresses by server. This paper describes the design and implementation, encountered problems during the beta-tests, and proposes their solutions. Requirements for the future possible changes on the protocol also are discussed.
Discourse Structures of English Exposition

Van Kuppevelt's approach to discourse structure emphasizes that topicality is the general organizing principle. His discourse structure consisting of MAIN STRUCTURE and SIDE STRUCTURE has been applied to conversations and discourse segmentations rather than expository essays. In this paper two discourse structures of expository essays are proposed in Van Kuppevelt's framework. The proposed structure can test the soundness of the ways of developing expository essays.
On Linear-Quadratic Stackelberg Games With Time Preference Rates

This note deals with linear-quadratic Stackelberg differential games including time preference rates with an open-loop information structure. The properties of the characteristic matrix associated with the necessary conditions for a Stackelberg strategy are pointed out. It is shown that such a matrix exhibits a special symmetry property of its eigenvalues. Sufficient conditions to guarantee a predefined degree of stability are given based on the distribution of the eigenvalues in the complex plane.
Fiscal Transparency, Measurement and Determinants: Evidence from 27 Developing Countries

Fiscal transparency has been consistently identified as a key feature of efficient fiscal policy and a prerequisite for good public governance. However, measuring fiscal transparency remains an empirical challenge, and extant literature on developing countries is still sparse. To that end, this paper examines the determinants of fiscal transparency in developing countries. We add to the existing literature by proposing a new replicable index of fiscal transparency that is consistent with the definition provided by the International Monetary Fund (IMF) and the World Bank. Additional determinants of fiscal transparency, which are exclusively relevant in the study of developing countries, are also examined. In particular, we introduce such factors as natural resources, the openness of the economy, the literacy rate of the population, and the quality of institutions. Because of possible endogeneity arising from interdependence among some variables, two-stage least squares (2SLS) is used to ensure that the estimators are consistent. As a robustness check, the same estimation procedure was replicated by replacing our index of fiscal transparency with respectively the index of Andreula et al. (2009) and the Open Budget Index, both of which use a significant similar number of developing countries of our selected sample. The results provide additional credence to our suggested procedure. The paper found that the level of natural resources and the openness of the capital account negatively affect fiscal transparency. However, the quality of institutions and literacy were found to positively affect fiscal transparency. The findings of this paper provide an explanation of why, after a decade of fiscal transparency programs, many developing countries are still lagging behind, thereby losing the potential benefits mentioned in the literature. These findings could help guide policies directed at improving fiscal transparency in the case of developing countries.
