Whither Women's Fear? Perceptions of Sexual Violence in Public and Private Space

This paper assesses explanations for women's fear of sexual violence. Many existing analyses share a common theoretical basis, but certain conflicts arise in the empirical evidence. These concern a number of paradoxes between fear and violence, in terms of their extent, their nature and in particular their spatial situation. A research project on women's fear of crime in Edinburgh aimed to improve understanding of these. Evidence from the questionnaire survey showed a further mismatch between women's common sense knowledge about general risks and their perceptions of personal risk. Many women know that the usual location of violence is private space, yet only fear attack in public places. Data from qualitative interviews suggest that this contradiction is preserved by the tendency to distance violence from the self, a process which is central to the management of danger and consequent lifestyle adaptation.
Burnout in Child Life Specialists: The Relation of Role Stress

The purpose of this research was to examine burnout in full-time child life specialists and to determine whether a relation existed between burnout and role stress (role ambiguity and role conflict) The relationship of individual and organizational variables to burnout were included as controls It was found that burnout exists for child life specialists, bur to a lesser degree than in other human service professionais Role ambiguity was a stronger predictor vanable of burnout than role conflict Additionally, the organizational variables contributed more to predicting burnout than the individual variables.
Analysis of stream-dependent tying structure for HMM-based speech synthesis

In conventional HMM-based speech synthesis framework, spectral features are modeled in one stream, and stream-dependent tree-based clustering was then applied for tying the model parameters. In this paper, we investigate several different stream-dependent tying structures for spectral features by splitting the feature vector into several streams. One splitting approach is to split each feature dimension into each stream. Another one is to split the static and dynamic features into different streams. Although splitting spectral features into different streams would ignore the correlation of context dependency between them, the number of model parameters can be optimized for each stream after stream-dependent clustering. From the experimental results, both splitting approaches can improve the quality of synthesized speech. However, the quality of synthesized speech became worse when we combined these two splitting approaches.
Children with Learning Disabilities within the Family Context: A Comparison with Siblings in Global Self–Concept, Academic Self–Perception, and Social Competence

This study examined the global self–concept, academic self–perception, social competence, and behavioral problems of 19 children with learning disabilities within the family context. Comparisons were made between the target children and their close–age siblings and family psychological correlates were identified. The participants were administered child assessment scales and rated by their parents, who also completed family psychosocial measures. The results show that although children with learning disabilities do not differ from their siblings in global self–concept and academic self–perception, their parents rated them to have less social competence and more behavior problems than their siblings. Moreover, the social competence and behavioral problems of children with learning disabilities are related to their parents’ stress. Educational and research implications are drawn.
Conversations among Coal Miners in a Campaign to Promote Hearing Protection

Although working in a coal mine can diminish one's hearing capabilities by 50%, not until 2000 did federal laws require companies to establish noise standards in order to help prevent hearing loss among their employees. Since then, researchers have worked with safety administrators to develop effective messages promoting hearing protection and testing. This research assessed the effects of campaign messages on discussing campaign postcards and talking with others about a helmet-sticker incentive. The results, which are discussed with a focus on future campaigns, indicate that hearing-related attitudes, intentions, and behaviors are the most influenced by messages that were affectively neutral and least influenced by messages that were affectively negative.
Surge Step Stress Testing ( SSST ) of Tantalum Capacitors

A misunderstanding of the failure mechanism of tantalum capacitors has created the fear of using these capacitors in high current applications. A capacitor depends on the dielectric as an insulative material and the plates as a conductive material. If the current was the trigger mechanism for failure, then the plates should be suspect throughout the life of the capacitor. This is not the case as the failures with this capacitor are normally related to initial power-on occurrences. As such, the failure mechanism is most likely the breakdown of the dielectric when exposed to a specific critical strain for the first time. The high available current ensures that the failure does not heal itself, but breaks down the dielectric so catastrophically that the dielectric loses most of its insulative properties. This Surge Step Stress Test (SSST) is intended to identify the critical stress level of any batch of capacitors to give some predictability to the power-on failure mechanism.
Building Knowledge and Community through Online Discussion

A web conference “adds value by generating discussion among a diverse student group” (Skinner, 2004a, p. 12). Or does it? A significant concern is the extent to which learners construct knowledge and develop a learning community through online discussion. Critics argue that genuine knowledge construction is difficult to achieve. This study examines two potentially innovative discussion ideas and finds that a lack of trust damages the sense of community and activities will fail for some students if knowledge construction is left to chance. Risks can be reduced by careful design where the specific characteristics of community and knowledge construction are deliberately planned.
Granular Material Interactive Manipulation: Touching Sand with Haptic Feedback

We present a novel approach for a virtual granular material interactive manipulation with force feedback. A user can interactively change a height-field model of sand by dragging objects inside. The virtual sand behaves like real sand moving to the sides and falling back, filling holes and irregularities on the surface. The dragging object position is controlled by a haptic device that provides a position in 3D space that correspondingly changes the sand model. The sand model provides force feedback to the haptic device resulting in two principal forces; the repulse that has vertical direction and the viscous drag. The resulting force is delivered back to the haptic device. The user can sense the sand’s response as the dragging object moves through the virtual sand. This results in the haptic-visual feedback providing a higher degree of plausibility than visual feedback alone.
Pancreatic Neuroendocrine Tumors: How Much Surgery is Safe?

Background: Neuroendocrine tumors of the pancreas (pNET) are rare. Often the patients are asymptomatic for a long time and present late with metastasized disease. Although there are guidelines for the treatment of these tumors, there is no clear consensus whether the resection of liver metastases may be combined with the primary tumor. Method: We retrospectively analyzed the patients operated at our institution between 1/2003 and 12/2012. The patients were analyzed for demographic and clinical data, surgical treatment, tumor size and stage, histology, complications, survival and tumor recurrence over time. Results: We analyzed 53 patients, 23 females, 30 males. Patients with a one-step surgical approach to pancreas and liver had similar morbidity and mortality compared to patients with disease confined to the pancreas. The primary tumors were smaller in tumors confined to the pancreas. Angioinvasion as well as positive lymph nodes were strongly correlated with synchronous or metachronous liver metastases. Progression free survival was shorter in patients with primary metastasized disease. Conclusion: The treatment of pNET is challenging. The surgical approach should be tailored to the patient’s general condition. Patients benefit from extended and combined resections even in metastasized or locally advanced situations. Combined pancreatic and hepatic surgery may be performed safely.
A Survey of the Stable Marriage Problem and Its Variants

The stable marriage problem is to find a matching between men and women, considering preference lists in which each person expresses his/her preference over the members of the opposite gender. The output matching must be stable, which intuitively means that there is no man- woman pair both of which have incentive to elope. This problem was introduced in 1962 in the seminal paper of Gale and Shapley, and has attracted researchers in several areas, including mathematics, economics, game theory, computer science, etc. This paper introduces old and recent results on the stable marriage problem and some other related problems.

How to use high aspect ratio anodic aluminum oxide (AAO) membranes as the etching and evaporation mask is one of the unsolved problems in the application of nanostructured arrays. Here we describe that the versatile utilizations of the highly ordered AAO membranes with high aspect ratio more than 20 as universal masks for formations of various nanostructure arrays on various substrates. The result shows that the fabricated nanopore and nanoparticle arrays of substrates inherit the regularity of the AAO membranes completely. The flat AAO substrates and uneven AAO frontages were attached to the Si substrates respectively as an etching mask, which demonstrates that the two kinds of the positive replication and negative replication are the replication of mirror of Si substrates relative to the flat AAO substrates and uneven AAO frontages. Our work is a breakthrough for the broad research field of surface nano-masking.
Assessing Citizenship Behavior in Educational Contexts

The present study developed a measure to assess citizenship behavior in educational settings and examined its antecedents and consequences in the cultural context. The results of this study provided discriminant validity for the newly extracted two-factor structure, that is, self-regulation and other-orientation. The authors identified both factors' motivation and personality correlates and added self-construals to predict citizenship behavior. Self-regulated citizenship behavior was positively related to intrinsic motivation and conscientiousness but negatively related to amotivation, whereas other-oriented citizenship behavior was significantly related to interdependent self-construal. Their differential effects on predicting life satisfaction showed that citizenship behavior has its own specific characteristics in educational contexts compared with industrial and organizational settings. Our findings also demonstrated the importance of cultural self-views in understanding communal behavior.
ANALYSIS STUDY ON CACHING AND REPLICA PLACEMENT ALGORITHM FOR CONTENT DISTRIBUTION IN DISTRIBUTED COMPUTING NETWORKS

Recently there has been significant research focus on distributed computing network massively caching and replica placement problems for content distribution in globally. Peer -to-Peer (P2P) network provides dynamically decentralized, self organized, scalable objects in distributed computing system. However such networks suffer from high latency, network traffic and cache update problems. The existing caching and replica placement techniques for placing objects across peer -to-peer network have no complete s olution to these problems. This paper presents an overview of the current challenges present in P2P overlay networks, followed by describes briefly the analysis study of the existing algorithms and their merits and demerits. And also suggest a new popular ity based QoS-aware(Quality of Service) smart replica placement algorithm for content distribution in peer - to-peer overlay networks which overcomes the access latency, fault tolerance, network traffic and redundancy problems with low cost. The new algo rithm suggested is based on the outcome of the analysis study.
Can We Get A Better Retrieval Function From Machine?

The quality of an information retrieval system heavily depends on its retrieval function, which returns a similarity measurement between the query and each document in the collection. Documents are sorted according to their similarity values with the query and those with high rank are assumed to be relevant. Okapi BM25 and their variations are very popular retrieval functions and they seem to be the default retrieval function for the IR research community; and there are many other widely used and well studied functions, for example, Pivoted TFIDF and INQUERY. Most of these retrieval functions being used today are made based on probabilistic theories and they are adjusted in real world according to different contexts and information needs. In this paper, we propose the idea that a good retrieval function can be discovered by a pure machine learning approach, without using probabilistic theories and knowledge-based techniques. Two machine learning algorithms, Support Vector Machine (SVM) and Genetic Programming (GP) are used for retrieval function discovery, and GP is found to be a more effective approach. The retrieval functions discovered by GP might be hard for human interpretation, but their performance is superior to Okapi BM25, one of the most popular functions. The new retrieval function is combined with query expansion techniques and the retrieval performance is improved significantly. Based on our observations in the empirical study, the GP function is more reliable and effective than Okapi BM25 when query expansion techniques are used.
The Internal Reliability of a General Mattering Scale in Homeless Men

199 homeless men were administered the General Mattering Scale to assess their belief that they mattered to others in their community. Analysis indicated that homeless men felt that they were important to others, that others pay attention to them, that they would be missed by others if they went away, that people were interested in what they had to say, and that others depended on them. The General Mattering Scale displayed strong internal consistency (Cronbach alpha of .85).
Complex, Corpus-Driven, Syntactic Features for Word Sense Disambiguation

Although syntactic features offer more speciﬁc information about the context surrounding a target word in a Word Sense Disambiguation (WSD) task, in general, they have not distinguished themselves much above positional features such as bag-of-words. In this paper we offer two methods for increasing the recall rate when using syntactic features on the WSD task by: 1) using an algorithm for discovering in the corpus every possible syntactic feature involving a target word, and 2) us-ing wildcards in place of the lemmas in the templates of the syntactic features. In the best experimental results on the SENSEVAL-2 data we achieved an F-measure of 53.1% which is well above the mean F-measure performance of of-ﬁcial SENSEVAL-2 entries, of 44.2%. These results are encouraging considering that only one kind of feature is used and only a simple Support Vector Machine (SVM) running with the defaults is used for the machine learning.
Research note Individual characteristics and expectations about opportunities in Australia among prospective Vietnamese migrants

The objective of this study was to describe the expectations about future opportunities in Australia among prospective Vietnamese migrants, and the association of these expectations with individual characteristics. We surveyed 1,352 prospective Vietnamese migrants aged 16 years or more who were recruited from a pre-departure medical screening programme for an Australian visa. Prospective migrants generally believed that future educational, socio-economic and employment opportunities in Australia were better than in Vietnam. Pre-migration socio-demographic characteristics and perceived health status were significantly and independently associated with expectations about future opportunities in Australia. Migrant expectations about educa tional, socio-economic and employment opportunities in Australia are modified by individual socio-demographic and health-related characteristics, which may also influence experiences post-migration.
Non-Hodgkin's lymphoma in childhood: clinical and epidemiological characteristics and survival analysis at a single center in Northeast Brazil.

OBJECTIVE To describe the clinical and demographic characteristics of non-Hodgkin's lymphoma patients diagnosed at the Pediatric Oncology Unit at the Instituto Materno-Infantil Professor Fernando Figueira (IMIP) over a 9-year period, and also to describe their survival rates and possible associations between the survival rates and the clinical and demographic characteristics analyzed in the study. METHODS This was a cross-sectional study. Data were collected by a retrospective review of the charts of all 110 patients admitted to our unit during the period of May 1994 through May 2003. Probability of survival was calculated in accordance with the techniques of Kaplan-Meier, using log rank to evaluate differences between the groups. RESULTS The average age was 6.1 years. The male/female ratio was 2.4:1. The most frequent histological subtype was Burkitt's lymphoma. The majority of patients had been diagnosed with advanced disease (stage III or IV of Murphy's Classification) and was from rural areas. Family income per capita was lower than 1/2 minimum wage in 36.4% of cases; maternal illiteracy was observed in 12.7% of cases. The 5-year overall survival and disease-free survival rates were 70+/-4% and 68.4+/-4%, respectively. None of the clinical-demographic characteristics had a significant association with the probability of survival (p > 0.05). CONCLUSION Children admitted to the IMIP seemed to be affected by non-Hodgkin lymphoma at a younger age, with a higher incidence of Burkitt's lymphoma and with survival rates similar to those described in the literature of developed countries. No clinical demographic characteristics had a statistically significant association with prognosis
Scaffolding bacterial genomes and probing host-virus interactions in gut microbiome by proximity ligation (chromosome capture) assay

Two proximity ligation approaches are used to probe the gut’s phage-bacteria infection network using Meta3C and GRAAL scaffolding. The biochemical activities of microbial communities, or microbiomes, are essential parts of environmental and animal ecosystems. The dynamics, balance, and effects of these communities are strongly influenced by phages present in the population. Being able to characterize bacterium-phage relationships is therefore essential to investigate these ecosystems to the full extent of their complexity. However, this task is currently limited by (i) the ability to characterize complete bacterial and viral genomes from a complex mix of species and (ii) the difficulty to assign phage sequences to their bacterial hosts. We show that both limitations can be circumvented using meta3C, an experimental and computational approach that exploits the physical contacts between DNA molecules to infer their proximity. In a single experiment, dozens of bacterial and phage genomes present in a complex mouse gut microbiota were assembled and scaffolded de novo. The phage genomes were then assigned to their putative bacterial hosts according to the physical contacts between the different DNA molecules, opening new perspectives for a comprehensive picture of the genomic structure of the gut flora. Therefore, this work holds far-reaching implications for human health studies aiming to bridge the virome to the microbiome.
The Effects of Long-term Exercise on Cerebral Function and the Maintenance of Concentration in the Elderly

The purpose of this study was to clarify the effect of long-term exercise on the maintenance of concentration, as an indicator of the activity level of the cerebral cortex, and on the Profile of Mood States (POMS) in healthy elderly persons. Forty-six subjects were divided into three groups: a long-term exercise group (LTE-G) of 21 subjects (mean age: 67 years); a health exercise group (HE-G) of 12 subjects (mean age: 69 years); and a sedentary control group (SC-G) of 13 subjects (mean age: 70 years). We assessed the target aiming function (TAF), the POMS, and the presence in the urine of the following compounds: 8-hydroxydeoxyguanosine (8-OHdG) and acrolein (ACR) as indicators of oxidative stress; adrenaline, noradrenaline, and dopamine as indicators of sympathetic nervous activity. The mean TAF-L values, which represent the level of mental concentration, were statistically lower in the LTE-G and HE-G than in the SC-G. The mean TAF-D values, indicating deviation levels, were significantly lower in the HE-G than in the SC-G. Total Mood Disturbance (TMD) scores, which are the scored totals of POMS tests, and the scores on the "Confusion" factor were clearly lower in the LTE-G and HE-G than in the SC-G. On the other hand, there were no significant differences in 8-OHdG, ACR, adrenaline, noradrenaline or dopamine values among the three groups. These results suggest that the continuation of exercise improves the cerebral cortical activity, the maintenance of concentration, and the POMS scores of healthy elderly persons.
