CRIME‐RELATED POST‐TRAUMATIC STRESS DISORDER IN ELDERLY PSYCHIATRIC PATIENTS: A CASE SERIES

Previous research has shown that fear of crime among the elderly is very common, and being a victim is not uncommon. There have been no descriptions of the impact of crimes on the mental health of the victims. In this study, 350 psychiatric patients were screened for post‐traumatic stress disorders (PTSD). One hundred of the patients had been victims, and five of the victims (5%) had PTSD. Their clinical characteristics are described. In this series, most crimes were not complicated by PTSD.
Trait-Behavior Relations and Dispositional Inference

Perceivers hold implicit expectations about the range of behavior implied by any given trait. This article distinguishes among four types of traits: capacities, morality traits, attitudes, and frequency based traits. Each type is described as having a unique pattern of trait-behavior relations, and several of these patterns are shown to relate to dispositional inference. The place of trait behavior relations within a general model of dispositional inference is outlined. The model describes a set of antecedents for the correction stage and divides correction into several interrelated operations: retrieval of attribution-relevant information (usually situational information), a decision-making operation in which the relevance of situational factors is considered along with trait-behavior relations, and an adjustment operation.
Signs, Symptoms, and Ill-Defined Conditions in Persian Gulf War Veterans: Findings From the Comprehensive Clinical Evaluation Program

Objective The purpose of this study was to analyze the type and frequency of signs, symptoms, and ill-defined conditions (SSID; International Classification of Diseases-9th Revision, Clinical Modification (ICD-9-CM) codes 780-799) identified by physicians evaluating Persian Gulf War veterans; to determine the influence of the extent of evaluation on the type and frequency of SSID diagnoses; and to search for evidence for a new illness, or illness related to wartime exposures, in veterans with ill-defined conditions. Method Comprehensive examinations were provided for 21,579 consecutive Persian Gulf War veterans with symptoms or health concerns after the war. Data recorded on all individuals includes demographics, self-reported exposures, symptoms, and physician-assigned ICD-9-CM primary and secondary diagnoses. A detailed psychosocial history, including a multidisciplinary discussion, was incorporated for a subset of participants. Results SSID conditions were primary diagnoses for 17.2% of veterans, and either primary or secondary diagnoses for 41.8%. Although some SSIDs were objective conditions (eg, sleep apnea), most were simply symptoms. More comprehensive evaluation, especially the multidisciplinary discussion of findings, decreased the frequency of symptoms as diagnoses and increased the number of DSM-IV psychiatric diagnoses. Ill-defined conditions were not associated with particular self-reported exposures or demographic variables. Conclusions Ill-defined conditions identified by physicians in Gulf War veterans are most often symptoms. More definitive, often psychological, diagnoses can be made by increasing the intensity of the evaluation and by multidisciplinary input. Evidence for a new or unique illness related to wartime exposures did not emerge from this analysis.
A Study of Online Misrepresentation, Self-Disclosure, Cyber-Relationship Motives, and Loneliness among Teenagers in Taiwan

The purpose of this study was to investigate the relationships between online misrepresentation (OM), self-disclosure (SD), cyber-relationship motives (CRM), and loneliness in teenagers. A survey was conducted using a sample of 608 Taiwanese teenagers (13 to 18 years of age). The instruments used include scales of loneliness, OM, and SD in real life (SD-R) and in cyberspace (SD-C). The findings show that 70.23% of teenagers report engaging in OM, indicating that it is a universal phenomenon. This study found no gender differences in reported OM and found that teenagers with online dating experiences exhibited different SD behavior online and offline. A multiple regression analysis showed that a lower valence of SD-R and an increase in the depth of control and accuracy of both SD-C and OM were predictive of teenagers' CRM with an overall middle level of explanatory power; further, lower accuracy and increased intent of SD-R, as well as increases in intentions of easier communication and sexual partners of CRM, were predictive of teenagers' OM, with overall low levels of explanatory power. Recommendations for future research are suggested.
FoxM1 Inhibition Sensitizes Resistant Glioblastoma Cells to Temozolomide by Downregulating the Expression of DNA-Repair Gene Rad51

Purpose: Recurrent glioblastoma multiforme (GBM) is characterized by resistance to radiotherapy and chemotherapy and a poor clinical prognosis. In this study, we investigated the role of the oncogenic transcription factor FoxM1 in GBM cells' resistance to alkylator temozolomide (TMZ) and its potential molecular mechanism. Experimental Design: FoxM1 expression levels were measured by immunohistochemical analysis in 38 pairs of primary and recurrent GBM tumor samples. Expression levels were also measured in primary recurrent GBM cell lines, and their responses to TMZ were characterized. In a mechanistic study, an siRNA array was used to identify downstream genes, and a chromatin immunoprecipitation assay was used to confirm transcriptional regulation. Results: Recurrent tumors that were TMZ resistant expressed higher levels of FoxM1 than did primary tumors. Recurrent GBM cell lines expressed higher levels of FoxM1 and the DNA damage repair gene Rad51 and were resistant to TMZ. TMZ treatment led to increased FoxM1 and Rad51 expression. FoxM1 knockdown inhibited Rad51 expression and sensitized recurrent GBM cells to TMZ cytotoxicity. FoxM1 directly regulated Rad51 expression through 2 FoxM1-specific binding sites in its promoter. Rad51 reexpression partially rescued TMZ resistance in FoxM1-knockdown recurrent GBM cells. A direct correlation between FoxM1 expression and Rad51 expression was evident in recurrent GBM tumor samples. Conclusion: Targeting the FoxM1-Rad51 axis may be an effective method to reverse TMZ resistance in recurrent GBM. Clin Cancer Res; 18(21); 5961–71. ©2012 AACR.
Anchoring data quality dimensions in ontological foundations

of an organization. A leading computer industry information service firm indicated that it “expects most business process reengineering initiatives to fail through lack of attention to data quality. ” An industry executive report noted that more than 60% of surveyed firms (500 medium-size corporations with annual sales of more than $20 million) had problems with data quality. The Wall Street Journal also reported that, “Thanks to computers, huge databases brimming with information are at our fingertips, just waiting to be tapped. They can be mined to find sales Anchoring Data Quality Dimensions Ontological Foundations
Efficient search for approximate nearest neighbor in high dimensional spaces

We address the problem ofdesigning data structures that allow efficient search f or approximate nearest neighbors. More specifically, given a database consisting ofa set ofvectors in some high dimensional Euclidean space, we want to construct a space-efficient data structure that would allow us to search, given a query vector, for the closest or nearly closest vector in the database. We also address this problem when distances are measured by the L1 norm and in the Hamming cube. Significantly improving and extending recent results ofKleinberg, we construct data structures whose size is polynomial in the size ofthe database and search algorithms that run in time nearly linear or nearly quadratic in the dimension. (Depending on the case, the extra factors are polylogarithmic in the size ofthe database.)

Freedom of Choice and Poverty Alleviation

Abstract The Capability Approach (henceforth CA) views poverty as a multidimensional phenomenon that is not only characterised by lows levels of achievement in the various dimensions but also by a restricted opportunity to choose among different ways of life. The CA thus puts a lot of emphasis on (limited) freedom of choice as a crucial aspect of poverty. If poverty is seen in this way there are two ways to improve the situation of the poor: by broadening the set of opportunities open to them or by strengthening their ability to choose. The paper concentrates on the latter. Although the CA discusses several possibilities for strengthening the ability to choose it does not explicitly consider the role of enhancing the capability of choosing as a means of poverty alleviation. The paper summarizes which circumstances are seen in the CA as suitable for strengthening freedom of choice. Namely, the paper discusses the market as an institution that trains the ability to choose, democracy as a political institution that is based on freedom of choice and participatory methods as an attempt to build explicitly on freedom of choice of the participants. Two shortcomings in the theoretical conceptualization of freedom of choice in the CA are identified by discussing these institutions and circumstances: first, the interplay between social structures and individual agency is not modelled in much detail within the CA. Second, the CA does not provide an explicitly temporal model of agency. The paper takes a closer look at these shortcomings from a sociological perspective since the questions they raise are core questions of sociology. The problems are intertwined. In order to tackle the problem of social embedding in the CA one needs to introduce time and processes as well. Sociological approaches show how social structures evolve from the interaction of individuals. The paper gives an example of how sociological concepts of this interaction can be used for drawing a model of social work for strengthening the agency of the poor. The paper proceeds as follows: first the view of poverty as capability deprivation is presented. The second section gives an overview of the areas in which the CA discusses the strengthening of individual choice: the market, democracy and participatory projects. The third section elaborates on the shortcomings of the CA identified in the preceding section from a sociological perspective and introduces a concept of social work developed in a similar theoretical context. The conclusion summarizes the lessons and outlines further lines of research.
Optimized Distributed Inter-Cell Interference Coordination (ICIC) Scheme Using Projected Subgradient and Network Flow Optimization

In this paper, we tackle the problem of multi-cell resource scheduling, where the objective is to maximize the weighted sum-rate through inter-cell interference coordination (ICIC). The blanking method is used to mitigate the inter-cell interference, where a resource is either used with a predetermined transmit power or not used at all, i.e., blanked. This problem is known to be strongly NP-hard, which means that it is not only hard to solve in polynomial time, but it is also hard to find an approximation algorithm with guaranteed optimality gap. In this work, we identify special scenarios where a polynomial-time algorithm can be constructed to solve this problem with theoretical guarantees. In particular, we define a dominant interference environment, in which for each user the received power from each interferer is significantly greater than the aggregate received power from all other weaker interferers. We show that the originally strongly NP-hard problem can be tightly relaxed to a linear programming problem in a dominant interference environment. Consequently, we propose a polynomial time distributed algorithm that is not only guaranteed to be tight in a dominant interference environment, but which also computes an upper bound on the optimality gap without additional computational complexity. The proposed scheme is based on the primal-decomposition method, where the problem is divided into a master-problem and multiple subproblems. We solve the master-problem iteratively using the projected-subgradient method. We also show that each subproblem has a special network flow structure. By exploiting this network structure, each subproblem is solved using the network-based optimization methods, which significantly reduces the complexity in comparison to the general-purpose convex or linear optimization methods. In comparison with baseline schemes, simulation results of the International Mobile Telecommunications-Advanced (IMT-Advanced) scenarios show that the proposed scheme achieves higher gains in aggregate throughput, cell-edge throughput, and outage probability.
Preschoolers' Communicative Functions During Shared Book Reading With Mothers and Fathers

Research Findings: This study examined whether the communicative behaviors of preschoolers during shared-reading interactions differ according to child age or parent gender. Twenty Italian preschoolers (from 3.1 to 5.11 years) were observed during book reading with each parent separately. Communicative behaviors were analyzed according to the speech act theory. The findings showed that older children produced significantly more requests with fathers than with mothers but significantly more assertions with mothers than with fathers. Sequential analysis showed that only the fathers' reading utterances were significantly followed by older children's requests. These results suggest that older children adjusted their communicative functions to elicit richer conversations from their fathers. Practice or Policy: These findings have implications for the assessment and support of preschoolers' conversational skills.
Embodied imitation-enhanced reinforcement learning in multi-agent systems

Imitation is an example of social learning in which an individual observes and copies another’s actions. This paper presents a new method for using imitation as a way of enhancing the learning speed of individual agents that employ a well-known reinforcement learning algorithm, namely Q-learning. Compared with other research that uses imitation with reinforcement learning, our method uses imitation of purely observed behaviours to enhance learning, with no internal state access or sharing of experiences between agents. The paper evaluates our imitation-enhanced reinforcement learning approach in both simulation and with real robots in continuous space. Both simulation and real robot experimental results show that the learning speed of the group is improved.
VEP: a virtual machine for extended proof-carrying code

One of the key issues with the practical applicability of Proof-Carrying Code (PCC) and its related methods is the difficulty in communicating the proofs which are inherently large. One way to alleviate this problem is to transmit, instead, a proof generator for the program in question in a generic extended PCC framework (EPCC). The EPCC needs to provide the execution of the proof generator at the consumer side in a secure manner. The ability to securely run arbitrary untrusted proof generator is a challenging problem. We explore the design of a small and safe virtual machine (VEP) which provides the EPCC with a robust security guarantee. The VEP is a minor TCB extension of less than 300 lines of code which works as a safe execution environment and brings about a practical solution to thecommon security and resource management issues.
“Welcome to Salón 110”: The Consequences of Hybrid Literacy Practices in a Primary-Grade English Immersion Class

Abstract This paper presents an analysis of the literacy practices in a primary-grade English immersion class in California during the first year of implementation of Proposition 227, the initiative that mandated English immersion education for a majority of the state’s linguistically diverse students. The data issue from a yearlong qualitative study of Room 110, a class consisting of 20 native Spanish-speaking children. The author utilizes the notion of hybrid literacy practices to conceptualize the blending of Spanish and English and home and school registers that permeated the class’s reading and writing activities. Findings illustrate the dynamic contexts of development created by these practices and ways that the linguistic hegemony operating within the school eclipsed the practices. A discussion of the findings emphasizes the ambivalence of hybridity as a conceptual tool and as a guide for instructional practice. The paper concludes with three interrelated principles gleaned from the analysis of Room 110’s literacy practices that elaborate dimensions of effective literacy learning environments for Latina/o children.
Bifrost : A Novel Anonymous Communication System with DHT

An immense amount of information is processed on the Internet due to its spread, increasing the severity of such problems as the disclosure of personal information; privacy protection is required. Research to protect anonymity has become crucial. Anonymous communication systems must consider a sudden breakaway of nodes. However existing systems isn't considering this enough. This paper proposes separating a node management layer from an anonymous communication layer. A novel anonymous communication system is realized by a node management layer that uses Chord, which is a distributed hash table, and the anonymous communication layer uses multiplex encryptions.
The Precision of Change Scores Under Absolute and Relative Interpretations

Although some progress has been made in rehabilitating change scores by showing that they are not necessarily unreliable, they are still generally thought to be less reliable than the measures from which they are derived. However, the focus on reliability or generalizability as a measure of the precision of change scores may be misguided because both reliability and generalizability coefficients assume a norm-referenced interpretation, whereas many applications of change scores rely on an absolute interpretation of the change. We examined the precision of change scores in terms of error-tolerance (E/T) ratios for both relative and absolute interpretations of change scores. E/T ratios are used to evaluate the error in estimating the change relative to the tolerance for error in a particular context. Achievement test data in which people are crossed with items within categories are used to illustrate the results.
Breakfast, attachment styles and health of female university students

The present research was carried out on the relationship between breakfast, attachment patterns and health of university students. Correlation research method was used in the study. Purposive sampling was used to collect the sample. Purpose of the study was to explore the link between the breakfast, attachment pattern and health of university students. A sample of 200 university students was selected for the research. Instruments used were Adult Nutrition and Performance Questionnaire, Relationship Questionnaire and General Health Questionnaire. Independent sample chi square was used to explore the relationship between breakfast and health outcome. It was concluded that university student who daily had their breakfast, had better health than those who had irregularity or they omitted breakfast. Analysis of variance was applied to determine the health among three models of attachment. Health among the three attachment styles was slightly insignificant.
Designing a knowledge management performance framework

Measuring the business benefits of knowledge management is difficult. Even more so for public sector agencies whose outcomes are social benefits, rather than simple profit. Describes an approach for measuring the performance of knowledge management strategies for a public sector agency in Victoria, Australia. Knowledge management is defined as those actions which support collaboration and integration. Two models are presented for measuring knowledge management performance and knowledge management behaviours: a performance framework based on the balanced scorecard approach, and a behaviour framework that identifies levels of practice demonstrated by individuals. The Knowledge Management Performance Scorecard maps the objectives for knowledge management across the balanced scorecard’s key result areas The Knowledge Management Behaviour Framework identifies seven levels of knowledge management skills for demonstrating collaborative behaviour. The framework also outlines what might be typical behaviours of managers and the roles they would assume in relation to individuals at each level.
Construction of algebraic-differential equations with given smooth and impulsive behaviour

The paper proposes a new method for the construction of a class of systems of algebraic and differential equations of the form A (ρ)β (t) = 0, ρ := dt where A (ρ) = A0 + A1ρ + · · ·+Aqρ ∈ R [ρ]r×r and det [A (ρ)] 6= 0 (A (ρ) is regular) with given smooth and impulsive behavior.
Probabilistic sonar filtering in scan matching localization

This paper describes a probabilistic sonar Altering technique dealing with sonar cross-talking and multiple reflections. The filtered sonar data is then used to feed the probabilistic scan matching algorithm spIC, which is also described. This scan matching algorithm deals with sonar range and angular errors. Experimental results demonstrate the utility of the combined use of probabilistic filtering and scan matching by evaluating the robustness, accuracy and computational cost. Also, the results obtained with spIC are compared with those provided by well known scan matching algorithms such as ICP and IDC.
Fuzzy Logic Based Objective Function Construction for Evolutionary Test Generation

The test case generation problem can be stated as an optimization problem whereby the closeness of test cases to violating the postcondition of a formal specification is maximized, subject to satisfying its precondition. This is usually implemented by constructing an objective function which provides a real-valued estimate of how distant all of the constraints are from being violated, and then trying to minimize it. A problem with this approach is that such objective functions may contain plateaux, which make their minimization hard. We propose a similar approach, grounded on fuzzy logic, which uses, instead of a "distance from violation" objective function, a fuzzy degree of proximity to postcondition violation and produces plateaux-free objective functions by construction. The approach is illustrated with the help of a case study on the functional (black-box) testing of computer programs.
A Two-Stage Ranking Scheme for Pseudo Relevance Feedback

As for the majority methods of Pseudo Relevance Feedback (PRF), the document in pseudo relevant set is generally divided into the relevant and the non-relevant according to user query. It is so coarse that the lower robustness of PRF, because there is still some relevant information in the non-relevant document and non-relevant information in the relevant document. A novel ranking scheme is proposed in this paper in order to accomplish a higher quality of pseudo relevant set. We try to realize automatically topic content analysis for pseudo relevant set, and divide pseudo relevant set into the relevant and the non-relevant at the document content level, so as to extract semantic relevant content for further selecting good expansion terms based on a smaller granularity, which would not worry about the cases that the top-ranked documents contain very few relevant documents. The experimental results on real Chinese collection show that our scheme can significantly improve the performance of retrieval.
