Retrospective Study of Fire Setting Among Boys in a Child Welfare Sample

This study aimed to assess fire-setting behaviors within a child welfare sample. The youth were divided into four groups based on their fire-setting behavior (e.g., no incidents, one incident, multiple minor incidents, and multiple severe incidents). Groups were compared based on five factors: overt antisocial behavior, covert antisocial behavior, global adjustment, psychiatric history, and learning deficits. Fire setters displayed more delinquent behavior and had more extensive psychiatric histories than non-fire-setting youth. Further, the youth with multiple serious incidents of fire-setting behavior displayed more delinquent behavior and had more extensive psychiatric histories than any of the fire-setting groups. These findings clearly suggest that fire setters, as a group, are not homogeneous with respect to antisocial behavior or psychiatric impairment and that gravity of fire setting increased as a function of greater psychopathology and greater delinquency when compared to their peers.
Overlay Cognitive Radio NOMA Networks with Selected Relay and Direct Link

In this paper, we propose an overlay cognitive radio (CR) non-orthogonal multiple access (NOMA) network to improve the performance of the primary receiver (PR) as well as the secondary receiver (SR). To accomplish the purpose, firstly, we adapt combining technology, selection combining (SC) and maximal ratio combining (MRC) which utilizing both signals from an indirect path and a direct path for the PR. Secondly, we select a relay which provides the spatial diversity gain among the candidate secondary sources (SSs) for the SR. The performance of the PR and the SR is derived in closed-form and verified through simulation. Numerical results demonstrate that the performance of the PR with SC or MRC always better than that of the PR of a conventional overlay CR NOMA system which receives from the indirect path only. Also, to maintain the same outage probability of the PR with MRC compared to that with SC at the given condition, 2 dB less transmit power is noticed. Furthermore, the performance of the SR with the selected relay improves with the increase of the number of the SSs. Consequently, we show that the proposed network, which assumes a direct link and adapts a selected relay, has better performance than the conventional overlay CR NOMA network.
The community‐level scaling relationship between leaf nitrogen and phosphorus changes with plant growth, climate and nutrient limitation

The scaling relationship between the concentrations of leaf nitrogen (N) and phosphorus (P), which can be formulated as [N] = α[P]β, shows the relative investment of plants in nutrient uptake. Most of the current knowledge on this topic is based on studies at the individual or species level. However, patterns at these levels can hardly reflect the response of vegetation or ecosystems along environmental gradients. Here, we explored how the nutrient demands of vegetation as a whole vary with productivity, climate and soil nutrient availability by generalizing the scaling relationship from the individual to the community level using community‐weighted mean data from shrub communities at 1,080 shrubland sites and tree communities at 2,087 forest sites across China. By comparing the community‐level leaf N–P scaling exponents under different conditions and using a bootstrapping method to construct continuous environmental gradients, we found that the scaling exponents declined with increased primary productivity (i.e. growth rate at the community level), temperature and water availability, indicating a higher P demand relative to N under these conditions. In addition, the scaling exponent of shrub communities had a declining trend, while that of tree communities had a rising trend, with higher soil N availability, showing a more resistant response of shrub communities to nutrient limitation. Synthesis. Our study demonstrates that leaf N–P scaling exponents could be used as indicators of plant growth conditions and, more importantly, that communities, as assemblages of plants, exhibits varied nutrient preferences and utilization strategies among different habitat conditions.
Overcoming Barriers in Supply Chain Analytics—Investigating Measures in LSCM Organizations

While supply chain analytics shows promise regarding value, benefits, and increase in performance for logistics and supply chain management (LSCM) organizations, those organizations are often either reluctant to invest or unable to achieve the returns they aspire to. This article systematically explores the barriers LSCM organizations experience in employing supply chain analytics that contribute to such reluctance and unachieved returns and measures to overcome these barriers. This article therefore aims to systemize the barriers and measures and allocate measures to barriers in order to provide organizations with directions on how to cope with their individual barriers. By using Grounded Theory through 12 in-depth interviews and Q-Methodology to synthesize the intended results, this article derives core categories for the barriers and measures, and their impacts and relationships are mapped based on empirical evidence from various actors along the supply chain. Resultingly, the article presents the core categories of barriers and measures, including their effect on different phases of the analytics solutions life cycle, the explanation of these effects, and accompanying examples. Finally, to address the intended aim of providing directions to organizations, the article provides recommendations for overcoming the identified barriers in organizations.

Research on Resource Allocation Optimization of Information Management System Based on Big data Association Mining

Aiming at the problem that the resource allocation accuracy of information management system in cloud computing environment is not high, the resource allocation method of information management system in cloud computing environment is improved and designed. A resource allocation algorithm of information management system is proposed based on big data association mining. The information of resource distribution in information management system is fused and reconstructed according to the key words and semantic association features, and then the feature extraction of association rules of information management system resources in cloud computing environment is carried out. The extracted association rules are used for big data training set to allocate the resources of information management system, and big data association mining and adaptive scheduling method are used for adaptive optimization control of resource allocation. The simulation results show that this method can improve the resource allocation accuracy of information management system, the anti-interference ability of resource allocation, and the efficiency of resource utilization and information management.
Methods and formal models of intelligent analysis of weakly structured data

The article presents a formal presentation of four ontologies of knowledge bases of the software environment: ontology of a problem area, linguistic ontology, ontology of precedents, ontology of rules for analyzing texts in natural language. When developing the knowledge base of the software environment, it is necessary to formulate requirements for the model of knowledge representation, the ontology. The development of a unified environment for semantic analysis of flows of weakly structured information that implements modern intelligent algorithms for processing text information will greatly facilitate the decision-making process by a specialist in the time constraint mode, due to the possibility of using a single unified bank of expert knowledge in the work of the question-answer system, and will also allow an automated semantic verification of information flows in order to provide information ion safety organization.
Advantages, Disadvantages, and Future Trends on the Use of Design of Experiments in Cross-Over Trials in Nutritional Clinical Investigation

The use of clinical trials to demonstrate effect of foods consumption on human health has increased significantly in recent years at the global level. As in other areas of human health, some authors choose to use parallel trial designs, while others prefer to use crossover designs for these trials. Because crossover trials have the advantage of reducing the number of subjects needed and the economic cost to be performed, they have many advocates within the scientific community. However, these types of tests also have numerous drawbacks, due to the difficulty of carrying out adequate statistical analyses, the lack of reliable standards adapted to them or confounding factors. In this chapter, the advantages and disadvantages of crossover designs and whether they are a recommended option for human nutrition research are shown. The usefulness of design of experiments coupled to crossover trials, especially when comparing various levels of the dependent variable, are also discussed.
Folic acid deficiency related to hyperhomocystinemia has less correlation with Gestational Diabetes Mellitus (GDM)

Gestational diabetes mellitus (GDM) is a different degree of the glucose intolerance that begins during pregnancy. GDM affects maternal and child health and is associated with a potential for preeclampsia, caesarean delivery due to macrosomic baby and type 2 diabetes in the mother, and with higher rates of perinatal mortally and many abnormalities in the infant. Homocysteine is a naturally occurring amino acid. Hyperhomocysteinemia(Hcy) is increased homocysteine levels which are associated folic acid deficiency. Hcy is regulated by several factors including genetically determined metabolic enzyme alteration, nutritional status, underlying disease, certain medication, age and pregnancy. A total of (40 case+40control) 80 patients are included in this study, it was observed that majority 21(52.5%) patients were age belonged to 31-35 years in case group and 17(42.5%) patients were age belonged to 31-35 years in control group. The mean age was found 30.5±4.2 years in case group and 29.05±4.2 years in control group. Majority 19(47.5%) patients had 3 rd gravida in case group and 20(50.0%) patients had 3 rd gravida in control group. Majority patients BMI belonged to 25-29.9 kg/m 2 (over weight) in both groups which was 21(52.5%) in case and 32(80.0%) in control group. The mean BMI was found 28.9±3.4 kg/m 2 in case and 28.53±2.9 kg/m 2 in control group. The difference was not statistically significant (p>0.05) between two groups. Studies have shown that folate deficiency is associated with increased homocysteine levels in blood. Update Dent. Coll. j: 2016; 6 (1): 01-07
Reproducibility of Diagnosis of ASC-US, Reflection of Diagnostic Criteria to Cervical Histopathological Results and Investigation of p16 Antibodies in Cervical Biopsies

Introduction: We aimed to investigate reproducibility of diagnosis, presence of Bethesda criteria and their reflection to histopathology in Papanicolau (PAP) smears with atypical squamous cells of undetermined significance (ASC-US). We also searched for p16 antibody positivity in cervical biopsy specimens of the patients with diagnosis of ASC-US. Methods: 33 patients who had undergone cervicopathologic evaluation were chosen from patients given ASCUS diagnosis in our department between 2006 and 2013 for this study. All the Pap smear specimens were reevaluated simultaneously by two pathologists. The specimens were evaluated for positivity of each Bethesda ASC-US diagnostic criteria separately. The biopsy specimens were stained with p16 antibody. Results: The reproducibility rate of cytology reports for Pap smear specimens diagnosed as ASC-US was found 88%. Neither of the Bethesda diagnostic criteria showed significant precedence over each other for frequency of
Lumbar corticospinal tract in rodents modulates sensory inputs but does not convey motor command

It is generally assumed that the main function of the corticospinal tract (CST) is to convey motor commands to bulbar or spinal motoneurons. Yet the CST has also been shown to modulate sensory signals at their entry point in the spinal cord, through primary afferent depolarization (PAD). By sequentially investigating different routes of corticofugal pathways, we here demonstrate that motor and PAD commands in mice belong to segregated paths within the CST. PAD is carried out exclusively by the CST via a population of lumbar interneurons located in the deep dorsal horn. In contrast, the cortex conveys the motor command via a relay in the upper spinal cord or supraspinal motor centers. At lumbar level, the main role of the CST is thus the modulation of sensory inputs, which is an essential component of the selective tuning of sensory feedback, to ensure well-coordinated and skilled movement. Impact statement While the corticospinal tract is often considered exclusively as a motor path, we here demonstrate that, in the mouse lumbar cord, its main role is the modulation of sensory inputs.

Analysis of profile of childhood kerosene poisoning in a tertiary care medical college hospital

Background: Children are very vulnerable to acute accidental poisoning. One of the most important poisoning in children is accidental ingestion of kerosene which is a common household substance. Its prevention plays a major role in reducing its morbidity and mortality in children. Objective: To understand the profile of accidental kerosene poisoning in children with special reference to symptoms, complications, radiological changes, course and outcome after treatment. Materials and Methods: Children hospitalized with acute poisoning at the paediatric intensive care unit (PICU) between January 1st 2010 and December 31st 2015 were retrospectively evaluated from hospital records. A detailed history was taken using the proforma having special reference to age, sex, poisoning agents and route of intake ,time of admission of the poisoned patients,socio- economic status of the family and cases with acute kerosene poisoning (AKP) were analysed. Results: In the PICU out of a total of 5806 patients admitted, 401 (6.9%) were due to acute poisoning . Among them AKP was noted in 91 (22.7%) patients and was second only to pharmaceutical medicine poisoning in 128 (28.7%) cases. All the children were admitted to the PICU, but most only required supportive care. There was no mortality following AKP during the study period. Conclusion: All paediatric age groups are at risk of AKP. Most children suffer due to unintentional poisoning because of easy availability of kerosene in their house itself. As AKP is preventable it must be given due importance in health control programs at all levels of health care.
Escalated BEACOPP Versus ABVD-Like Chemotherapy for Hodgkin Lymphoma Patients: a Cochrane Review.

Abstract 3705 Poster Board III-641 Introduction The main challenge in treating Hodgkin lymphoma (HL) is to find the optimal treatment with the best efficacy and least toxicity. So far there are two different international standards for the treatment of intermediate and advanced stage HL: chemotherapy with ABVD regime and chemotherapy with escalated BEACOPP regime. This review aims to clarify advantages and disadvantages of both treatments. Methods MEDLINE, CENTRAL and EMBASE were systematically searched for randomised controlled trials from 1985 to 2008. Trials comparing treatment with at least 2 cycles escalated BEACOPP versus chemotherapy with at least 4 cycles of ABVD within patients in intermediate or advanced stages HL were included. Trials without any published results will be excluded from the meta-analysis. Trial selection, quality assessment and data extraction were done independently by two review authors. Time-to-event outcome were analyzed with hazard ratios (HR) and 95% confidence interval (CI) in a fixed effects model. Results A total of 683 references were screened. Four eligible trials with 1970 patients were identified and included in the main analysis: the HD9 and HD14 trials from Germany, the HD2000 and GSM-HD trials from Italy. The escalated BEACOPP regime was more toxic during treatment than ABVD. Progression free survival (PFS) was statistically significantly longer for escalated BEACOPP: HR was 0.53 (95% CI [0.42, 0.67], I2=0%). In the main analysis of overall survival (OS), escalated BEACOPP was statistically significantly better than ABVD: HR was 0.70 (95% CI [0.50, 0.98], I2=0%). However, this result is not robust. In the OS-analysis restricted to advanced stage trials, the HR was 0.93 (95% CI [0.52, 1.04], I2=0%). Due to the high weight of the HD9 trial (57%), the OS-results are strongly influenced by this trial. In a sensitivity OS analysis without the HD9 trial the HR was 0.83 (95% CI [0.50, 1.38]). Only one trial (HD9) had a follow-up of over 5 years; the median of the other trials was approx. 3 years. Conclusions This meta-analysis showed a better PFS and suggests a benefit in OS for escalated BEACOPP in comparison to ABVD-like regimen. However, many trials had a short follow-up. Longer follow-up and the inclusion of the ongoing EORTC 20012 trial should allow a more definitive answer concerning OS. Disclosures: No relevant conflicts of interest to declare.
Prospects for Anion-Exchange Membranes in Alkali Metal–Air Batteries

Rechargeable alkali metal–air batteries have enormous potential in energy storage applications due to their high energy densities, low cost, and environmental friendliness. Membrane separators determine the performance and economic viability of these batteries. Usually, porous membrane separators taken from lithium-based batteries are used. Moreover, composite and cation-exchange membranes have been tested. However, crossover of unwanted species (such as zincate ions in zinc–air flow batteries) and/or low hydroxide ions conductivity are major issues to be overcome. On the other hand, state-of-art anion-exchange membranes (AEMs) have been applied to meet the current challenges with regard to rechargeable zinc–air batteries, which have received the most attention among alkali metal–air batteries. The recent advances and remaining challenges of AEMs for these batteries are critically discussed in this review. Correlation between the properties of the AEMs and performance and cyclability of the batteries is discussed. Finally, strategies for overcoming the remaining challenges and future outlooks on the topic are briefly provided. We believe this paper will play a significant role in promoting R&D on developing suitable AEMs with potential applications in alkali metal–air flow batteries.

Hybrid Massive MIMO Two-Way Relaying With Users and Relay Hardware Impairments

Most of the existing spectral efficiency (SE) investigations for massive multi-input multi-output (MIMO) relaying assume that each antenna has a dedicated radio-frequency (RF) chain with high-quality user and relay hardware. We consider a hybrid massive MIMO multi-pair two-way half-duplex relay, wherein each RF chain steers multiple antennas and assume that both users and relay have hardware impairments. We derive i) a novel closed-form SE expression using large-scale approximation; and ii) asymptotic SE expressions for two different power scaling schemes. We numerically demonstrate that i) a hardware-impaired hybrid relay has measurably degraded SE than a hardware-impaired conventional full-RF chain relay; and ii) the impact of hardware impairments do not vanish asymptotically as $N\rightarrow \infty$, mainly due to users hardware impairments.
