Xbox 360 Kinect Exergames for Health

Abstract This “eye-opener” review briefly surveys the current Kinect exergame titles for the Xbox 360 (Microsoft, Redmond, WA) (up to July 2012), focusing on possible uses by different age groups, from kids to older people, for improving players' physical, mental/cognitive, and psychological/emotional health and fitness. A quick survey of existing related research is also provided, and links are made to it. There are already many published studies about digital exergames in general, but very little about Kinect exergames. More research is needed to establish the evidence base concerning the latter (e.g., in relation to obesity management [pediatric and adult] or cognitive state improvement in older people, etc.): What works in each condition, what does not, and under which settings and criteria.
Evaluating the psychometric properties of the AUDIT-C among college students

Abstract Aims: Despite the various settings and diverse populations in which the utility of the AUDIT-C has been examined, college students have remained conspicuously absent from the vast majority of these studies. We evaluated the psychometric properties of the AUDIT-C with a sample of college student bar patrons. Methods: Intercept interviews were used to recruit currently enrolled college students (n = 347) exiting bars. A brief face-to-face interview assessed demographic data, alcohol-related behaviors (AUDIT-C), and breath alcohol concentration (BrAC). AUDIT-C responses were subjected to a principal component analysis. BrAC was used as a measure of concurrent validity against two distinct gender-based AUDIT-C cut-off scores. Results: All AUDIT-C items loaded on a single factor, accounting for 68% of total variance. Pearson’s product–moment correlation coefficients between BrAC and both hazardous drinking AUDIT-C cut-offs (r = 0.32; r = 0.38) were statistically significant (p < 0.001). Moreover, those meeting each hazardous drinking gender-based criteria exhibited significantly higher (p < 0.001) BrAC readings than those not meeting these criteria. Effect sizes for these group differences were considerable (Cohen’s d > 0.70). Reliability and stability statistics indicated strong internal consistency. Conclusions: Results reported herein highlight the sound psychometric qualities of the AUDIT-C and its ability to produce valid and reliable scores among college students.
INFLUENCE OF STRATEGIC BUYER SUPPLIER ALLIANCE ON PROCUREMENT PERFORMANCE IN PRIVATE MANUFACTURING ORGANIZATIONS

As firms increasingly emphasize cooperative relationships with critical suppliers, executives of buyer firms are using supplier evaluations to ensure that their performance objectives are met. Supplier evaluations, one type of supplier development program (SDP), are an attempt to meet current and future business needs by improving supplier performance and capabilities. The purpose of this study was to determine how suppliers perceive the buying firm’s supplier evaluation communication process and its impact on suppliers’ performance. Therefore, understanding strategic buyer supplier alliance will have an impact on procurement performance The main objective of the study was to examine the influence of strategic buyer supplier alliance on procurement performance in a private sector organization. The specific objectives of the study were: to assess the effects of governance structure on the procurement performance of Glaxo Smithkline ; to find out how technology impacts on the procurement performance of Glaxo Smithkline ; to establish how top management support affects the procurement performance of Glaxo Smithkline and to establish the effect of awareness of procurement policy and legal framework on the procurement performance of Glaxo Smithkline . A case study design was used for this study and targeted 100 management staff of Glaxo Smithkline . They were stratified according to departments of interest for the purposes of the study, i.e. Administration,
HPRS: A Hybrid P2P Reputation System using File and Peer Rating

Peer-to-peer file sharing networks have gained a lot of popularity and are burgeoning day by day. The widespread use inevitably produces malicious peers who try to disrupt the network by flooding it with in authentic files. This necessitates the need for a robust reputation system to identify bad peers and files. The former has been extensively studied and many peer based reputations already exist. In this paper we present a novel framework for a Hybrid P2P Reputation System (HPRS) using peer and file rating. This combined rating enables good peers to judge individual files and thus eliminate any in authentic downloads. It also helps a peer extract the maximum from the system by enabling him to get those occasional good files from bad peers and reject accidental bad files from good peers. Simulation results illustrate that HPRS significantly improves performance in a network.
EFFECT OF CROSSWORD CONTEXT ON PLOSIVE IDENTIFICATION IN NOISE FOR NATIVE AND NON-NATIVE LISTENERS

Studies of second language speech perception can highlight the role of prior knowledge in native language processing. The current study compared native and non-native identification of plosives in words spliced from natural utterances when presented in noise, with and without the context of the preceding word. Both listener groups performed at the same level in the absence of context at high noise, suggesting that the cues surviving energetic masking and splicing were similar for the two languages or that they had already been acquired by the non-native group. However, native listeners gained significantly more when contextual information in the preceding word was present, indicating that cross-word, extra-syllabic, cues are not so easily exploited by non-native listeners. An acoustic analysis revealed subtle durational differences in the preceding word rhyme, knowledge of which may contribute to the native advantage. Other possible explanations for the native benefit from cross-word context are discussed.
Development of high‐grade lymphoma in Helicobacter pylori‐infected C57BL/6 mice

Helicobacter pylori infection is associated with chronic gastritis, peptic ulcer disease, gastric adenocarcinoma and MALT lymphoma. Mice with H. pylori infection develop severe gastritis and atrophic changes in their stomachs after 6 months. We followed H. pylori‐infected animals for 13 months to find out whether dysplasia, carcinoma or lymphoma developed. Six‐week‐old C57BL/6 mice were infected with the CagA‐positive and VacA‐positive H. pylori mouse‐passaged strain 119/95, fed a low antioxidant diet, and kept in microisolated cages. Histopathological changes were examined after 13 months' infection. All H. pylori‐inoculated mice (n=5) developed a gastric squamous papilloma with nagging of the lamina muscularis after 13 months. Three out of five animals developed high‐grade B‐cell lymphoma derived from a MALT lymphoma at the squamous‐corpus border with manifestations also in the liver, spleen and kidney. There was a suspicion of local gastric lymphoma in the two remaining mice but with no significant changes in the liver, spleen or kidney. The normal control mice showed no pathological changes in any of these organs. It is concluded that this mouse model with infection by the CagA‐positive, vac‐toxin‐producing H. pylori strain 119/95 is suitable for use in the study of lymphoma development and also development of squamous cell papilloma with proliferative features.
Neural Coding of Movement Direction in the Healthy Human Brain

Neurophysiological studies in monkeys show that activity of neurons in primary cortex (M1), pre-motor cortex (PMC), and cerebellum varies systematically with the direction of reaching movements. These neurons exhibit preferred direction tuning, where the level of neural activity is highest when movements are made in the preferred direction (PD), and gets progressively lower as movements are made at increasing degrees of offset from the PD. Using a functional magnetic resonance imaging adaptation (fMRI-A) paradigm, we show that PD coding does exist in regions of the human motor system that are homologous to those observed in non-human primates. Consistent with predictions of the PD model, we show adaptation (i.e., a lower level) of the blood oxygen level dependent (BOLD) time-course signal in M1, PMC, SMA, and cerebellum when consecutive wrist movements were made in the same direction (0° offset) relative to movements offset by 90° or 180°. The BOLD signal in dorsolateral prefrontal cortex adapted equally in all movement offset conditions, mitigating against the possibility that the present results are the consequence of differential task complexity or attention to action in each movement offset condition.
Epidemiological investigation of expressive language delay at age two

Two studies are presented investigating the feasibility of using the Language Development Survey (LDS), a vocabulary checklist completed by parents, for the epidemiological investigation of the prevalence of expressive language delay in 2-year-olds. Two samples of upper-middle class toddlers were studied (Study 1: N = 108; Study 2: N = 92). Mean vocabulary reported was 195 words in Study 1 and 184 words in Study 2, with 13% and 15% of the respective samples reported to have fewer than 50 words of vocabulary. The correlation between reported LDS vocabulary and total number of Bayley objects and Stanford-Binet pictures named by the child was 0.78 in Study 1 and 0.82 in Study 2. In both studies, the LDS exhibited excellent sensitivity and specificity for the identification of language delay at 2 years old. Results of the two studies suggest that the LDS can be a useful and practical tool for the epidemiological identification of expressive language delay in 2-year-olds in the general population.
Assessing Cognitive Complexity in Java-Based Object-Oriented Systems: Metrics and Tool Support

Software cognitive complexity refers to how demanding the mental process of performing tasks such as coding, testing, debugging, or modifying source code is. Achiev- ing low levels of cognitive complexity is crucial for ensuring high levels of software main- tainability, which is one of the most rewardful software quality attributes. Therefore, in
Prefrontal Cortex Activity Associated with Source Monitoring in a Working Memory Task

Using functional magnetic resonance imaging (fMRI), we investigated prefrontal cortex (PFC) activity during remembering specific source information (format, location judgments) versus remembering that could be based on undifferentiated information, such as familiarity (old/new recognition ON, recency judgments). A working memory (WM) paradigm with an immediate test yielded greater activation in the lateral PFC for format and location source memory (SM) tasks than ON recognition; this SM-related activity was left lateralized. The same regions of PFC were recruited in Experiment 2 when information was tested immediately and after a filled delay. Substituting recency for location judgments (Experiment 3) resulted in an overall shift in task context that produced greater right PFC activity associated with ON and recency tasks compared to the format task, in addition to left SM-related activity. These data extend to WM previous findings from long-term memory (LTM) indicating that the left and right PFC may be differentially involved in memory attributions depending on the specificity of information evaluated. The findings also provide evidence for the continuity of evaluative processes recruited in WM and LTM.
Reduced nuclear export of HuR mRNA by HuR is linked to the loss of HuR in replicative senescence

The RNA-binding protein, HuR, associates with the HuR mRNA, but the consequences of this interaction are unknown. Here, we use human diploid fibroblasts (HDFs) and cervical carcinoma cells to study this regulatory paradigm. Ectopic overexpression of HuR potently enhanced the translation and cytoplasmic levels of endogenous HuR, but did not affect HuR mRNA levels. Inhibition of CRM1 function by Lemptomycin B or by knockdown of CRM1 greatly diminished the cytoplasmic levels of endogenous HuR mRNA and hence blocked the induction of endogenous HuR by exogenous HuR. Further studies showed that HuR interacted with the 3′-untranslated region (UTR) of HuR and that overexpression of HuR increased the cytoplasmic levels of a chimeric luciferase-HuR 3′-UTR reporter transcript, as well as luciferase activity; conversely, HuR knockdown reduced both parameters. Moreover, the loss of HuR in senescent, late-passage HDFs was accompanied by a reduced cytoplasmic presence of endogenous HuR mRNA, ectopic Luc-HuR-3′UTR reporter transcript, and luciferase activity relative to what was observed in young, early-passage cells. Our results reveal a positive feedback mechanism for the regulation of HuR, which may play an important role in the regulation of HuR during replicative senescence.
Face Authentication System for Information Security

This paper proposes the combination two facial feature methods and probabilistic neural network for facial recognition. Firstly, we use horizontal projection of 2-D image to obtain accumulated energy profile signal. Secondly, we obtain the statistical distribution of facial gray images. Finally, we adopt wavelet transform to extract low frequency coefficients from 1-D energy profile signal and statistical distribution of facial gray images as feature vectors, which is applied with probabilistic neural network in facial identification and facial matching. Thus, the proposed method is evaluated on the ORL face database for face recognition. Besides, the face authentication system is also built on PC, and it is evaluated on real data set by the proposed algorithm. The experiment results show that the proposed method possesses the excellent performance. Because of low complexity, it is also suitable for a hardware-friendly and resource-constrained embedded environment.
Cognitive function, gait speed decline, and comorbidities: the health, aging and body composition study.

BACKGROUND Emerging evidence indicates an association between cognitive function and physical performance in late life. This study examines the relationship between cognitive function and subsequent gait speed decline among high-functioning older adults. METHODS Measures of global cognitive function (Modified Mini Mental State Examination [3MS]) and executive control function (ECF) (a clock drawing task [CLOX 1] and the 15-item Executive Interview [EXIT 15]) were obtained in the Health, Aging, and Body Composition Study in 1999-2000. Gait-speed (meters/second) was assessed over 20 meters at usual pace. Using a mixed model, we assessed the relationship between baseline cognitive function and gait-speed change over 3 years. RESULTS Two thousand, three hundred forty-nine older adults (mean age 75.6 +/- 2.9 years) completed the assessments. After adjustment for baseline gait speed, a 1-standard-deviation (SD) lower performance on each cognitive test was associated with greater gait-speed decline over 3 years: 0.016 m/s for the 3MS (SD = 8.1), 0.009 m/s for CLOX 1 (SD = 2.4), and 0.012 m/s for EXIT 15 (SD = 4.1) (p <.0005 for all). After adjustment for comorbidities, the effect size was attenuated for 3MS and CLOX 1, and the association for EXIT 15 was no longer significant. Depression score was most strongly associated with the EXIT 15 effect reduction. CONCLUSION Global and executive cognitive functions predict declines in gait speed. The association of ECF with gait speed decline is attenuated by comorbid conditions, particularly depression. Elucidation of the mechanisms underlying these associations may point to new pathways for the treatment of physical decline associated with diminished cognitive function.
Aflatoxin B1 Degradation by Stenotrophomonas Maltophilia and Other Microbes Selected Using Coumarin Medium

Aflatoxin B1 (AFB1) is one of the most harmful mycotoxins in animal production and food industry. A safe, effective and environmentally sound detoxification method is needed for controlling this toxin. In this study, 65 samples were screened from various sources with vast microbial populations using a newly developed medium containing coumarin as the sole carbon source. Twenty five single-colony bacterial isolates showing AFB1 reduction activity in a liquid culture medium were selected from the screen. Isolate 35-3, obtained from tapir feces and identified to be Stenotrophomonas maltophilia, reduced AFB1 by 82.5% after incubation in the liquid medium at 37 °C for 72 h. The culture supernatant of isolate 35-3 was able to degrade AFB1 effectively, whereas the viable cells and cell extracts were far less effective. Factors influencing AFB1 degradation by the culture supernatant were investigated. Activity was reduced to 60.8% and 63.5% at 20 °C and 30 °C, respectively, from 78.7% at 37 °C. The highest degradation rate was 84.8% at pH 8 and the lowest was only 14.3% at pH 4.0. Ions Mg2+ and Cu2+ were activators for AFB1 degradation, however ion Zn2+ was a strong inhibitor. Treatments with proteinase K, proteinase K plus SDS and heating significantly reduced or eradicated the degradation activity of the culture supernatant. The results indicated that the degradation of AFB1 by S. maltophilia 35-3 was enzymatic and could have a great potential in industrial applications.

Multi-scale modelling of the dynamics of cell colonies: insights into cell-adhesion forces and cancer invasion from in silico simulations

Studying the biophysical interactions between cells is crucial to understanding how normal tissue develops, how it is structured and also when malfunctions occur. Traditional experiments try to infer events at the tissue level after observing the behaviour of and interactions between individual cells. This approach assumes that cells behave in the same biophysical manner in isolated experiments as they do within colonies and tissues. In this paper, we develop a multi-scale multi-compartment mathematical model that accounts for the principal biophysical interactions and adhesion pathways not only at a cell–cell level but also at the level of cell colonies (in contrast to the traditional approach). Our results suggest that adhesion/separation forces between cells may be lower in cell colonies than traditional isolated single-cell experiments infer. As a consequence, isolated single-cell experiments may be insufficient to deduce important biological processes such as single-cell invasion after detachment from a solid tumour. The simulations further show that kinetic rates and cell biophysical characteristics such as pressure-related cell-cycle arrest have a major influence on cell colony patterns and can allow for the development of protrusive cellular structures as seen in invasive cancer cell lines independent of expression levels of pro-invasion molecules.
Evaluating sustainability in organisations with a fuzzy logic approach

– The aim is to determine whether the organisations more strategically committed to their stakeholders present better social and financial performance and, based on this relationship, to determine the state of the art of the Spanish sectors' approach to sustainable development. , – This paper analyses the sustainability approach of a sample of 52 Spanish listed firms. This process is based on the study of different indexes generated in order to evaluate the company's commitment through its stakeholders, the social and financial performance of these organisations, and the relationship between them. Previous results showed a positive and not significant relationship between these variables and a positive financial performance. This paper replicates a former research by introducing a fuzzy‐ logic‐based methodology in order to generate the aforementioned indexes. , – The current results support the conclusions formerly obtained and simultaneously demonstrate that big Spanish companies are at an incipient stage of development of a clearly sustainability‐oriented management. , – The unavailability of a long series of organisations' sustainability information is an obstacle for a broader analysis. This research could motivate the usefulness of the fuzzy logic methodology for analysing the business sustainability approach and to develop studies on the corporate social performance. , – The use of fuzzy logic methodology for the generation of indexes related to the organisation's social responsibility and sustainability results.
The Analysis of Extension Theory on Wealth Effect in Stock Market of China

Stock market's wealth effect is-remarkable in developed country. In recent years, the question about stock market's wealth effect of China had become the focal thesis which many domestic and foreign scholars pay attention to. The conclusion of these researches is that stock market's wealth effect is faint from theory and demonstration in China, although development of stock market has more and more influence on the whole national economy in China. The article studies the question again proceeding with the concept of wealth effect. But this article tries to explain the reason of faint wealth effect of stock market in China further through four aspects such as the goal, the characteristic of market environment, supervising and other factors which using the basic theory and method of a new developing science - the extension theory, which solves incompatible problems by transforming and utilizing special symbol and formula. Then we know that stock market's wealth effect is faint in China from the goal, depth and extent (such as the amount of investors and the quantity of fund), the steady extent of run, the quality of company, the extent of supervising and others. Finally, the article advises several proposals to strengthen wealth effect of stock market in China by establishing the model of the matter element analysis: (1) building a stable, durative and flourishing securities market; (2) expanding stock market scale step by step; (3) enhancing the credit-building of listed corporation (such as establishing the true modern enterprise system, raising and establishing one batch appraisal organization which have social credit, establishing reporting and complaint station to enhance supervision of social and public); (4) protecting the interest of small investors; (5) strengthening supervising and management of the stock market; (6) reducing the stock market transaction cost. These proposals are useful to government of our country at presents
Sahlqvist theory and transfer results for hybrid logics

In the first part, we prove completeness for Sahlqvist extensions of the basic hybrid logic, and we prove that the basic hybrid logic has the Beth property. We also show that extensions of the basic hybrid logic that contain Sahlqvist formulas as well as pure formulas are in general not complete. In the second part, we define for every Kripke complete modal logic L its hybrid companion LH and investigate which properties transfer from L to LH . For a specific class of logics, we present a satisfiability-preserving translation from LH to L. We prove that for this class of logics, complexity, (uniform) interpolation, and finite axiomatization transfer from L to LH . We also provide examples showing that, in general, none of complexity, decidability or the finite model property transfer.
