Fast Sublinear Sparse Representation using Shallow Tree Matching Pursuit

Sparse approximations using highly over-complete dictionaries is a state-of-the-art tool for many imaging applications including denoising, super-resolution, compressive sensing, light-field analysis, and object recognition. Unfortunately, the applicability of such methods is severely hampered by the computational burden of sparse approximation: these algorithms are linear or super-linear in both the data dimensionality and size of the dictionary. We propose a framework for learning the hierarchical structure of over-complete dictionaries that enables fast computation of sparse representations. Our method builds on tree-based strategies for nearest neighbor matching, and presents domain-specific enhancements that are highly efficient for the analysis of image patches. Contrary to most popular methods for building spatial data structures, out methods rely on shallow, balanced trees with relatively few layers. We show an extensive array of experiments on several applications such as image denoising/superresolution, compressive video/light-field sensing where we practically achieve 100-1000x speedup (with a less than 1dB loss in accuracy).

Comparing telework locations and traditional work arrangements: Differences in work‐life balance support, job satisfaction, and inclusion

Purpose – The purpose of this paper is to examine differences in work‐life balance (WLB) support, job satisfaction, and inclusion as a function of work location.Design/methodology/approach – Web‐based survey data were provided by 578 employees working at one of four locations (main office, client location, satellite office, and home). Multiple regression analyses were used to identify differences in WLB support, job satisfaction, and inclusion across employees working at the four locations.Findings – Results showed that main office and home‐based workers had similar high levels of WLB support and job satisfaction. Main office workers reported higher levels of WLB support than satellite and client‐based workers. Additionally, main office workers reported the highest levels of workplace inclusion.Research limitations/ implications – Data were originally gathered for practical purposes by the organization. The research design does not allow for manipulation or random assignment, therefore extraneous variable.
The Relationship Between Alexithymia, Wellness, and Substance Dependence

This study examined the relationship between alexithymia, wellness, and substance dependence. Exploration of the relationship between alexithymia, emotional development, and wellness is largely absent in the literature, as is the use of wellness orientation in substance dependence treatment. This study was constructed from two samples, substance dependent clients in residential treatment in New Orleans, LA, and Austin, TX, and undergraduates from the University of New Orleans and the University of Texas at Austin. The total sample size for the study was n = 200. Each participant was administered the TAS-20 and the WEL. Four groups of n = 50 were formed from undergraduates and substance dependent clients based on their scores on the TAS-20: alexithymic undergraduates, non-alexithymic undergraduates, alexithymic substance dependent clients, and non-alexithymic substance dependent clients. Overall wellness as measured by the WEL was found to be greater for non-alexithymic participants than alexithymic participants using four different ANOVA group comparisons. These results are important to clinicians working with substance abuse, to researchers interested in alexithymia, emotional development, and wellness; and to counselors and counselor educators.
LEARNING IN DOING: SOCIAL, COGNITIVE AND COMPUTATIONAL PERSPECTIVES

The authors in this collection use Vygotsky’s cultural-historical theory of human development to frame their analyses of schooling, with particular emphasis on the ways in which literacy practices are mediated by social interaction and cultural artifacts. This volume extends Vygotsky’s cultural-historical theoretical framework to embrace nuances of learning and development that are influenced by culture as instantiated through the experiences of race, ethnicity, and language variation. Rather than seeking to provide definitive answers to social questions using Vygotsky’s core principles, the authors wrestle with educational problems through the mediation of Vygotsky’s theory. In doing so, they both sharpen their focus on the problems and speak back to Vygotsky, helping to extend the foundation of his work to address modern problems. This collection serves as a form of collaborative inquiry that itself will stimulate further consideration of these topics and further learning with Vygotsky about the ways in which individuals and social groups inquire and learn.
Cognitive performance and the thymus among HIV-infected subjects receiving HAART

Objective: To evaluate the impact of alcohol use, which is widespread in human immunodeficiency virus (HIV)+ individuals, on highly active antiretroviral therapy (HAART)-associated immune and cognitive improvements and the relationship between those two responses. Methods: In a case-control longitudinal study, thymic volume, cognition, and immune responses were evaluated at baseline and after 6 months therapy in HIV+ and HIV- controls. Cognitive performance was evaluated using the HIV Dementia Score (HDS) and the California Verbal Learning Test (CVLT). Results: Prior to HAART, thymic volume varied considerably from 2.7 to 29.3 cm3 (11 ± 7.2 cm3). Thymic volume at baseline showed a significantly inverse correlation with the patient’s number of years of drinking (r2 = 0.207; p < 0.01), as well as HDS and the CVLT scores in both HIV-infected (r2 = 0.37, p = 0.03) and noninfected (r2 = 0.8, p < 0.01). HIV-infected individuals with a small thymic volume scored in the demented range, as compared with those with a larger thymus (7 ± 2.7 vs. 12 ± 2.3, p = 0.005). After HAART, light/moderate drinkers exhibited thymus size twice that of heavy drinkers (14.8 ± 10.4 vs. 6.9 ± 3.3 cm3). Conclusions: HAART-associated increases of thymus volume appear to be negatively affected by alcohol consumption and significantly related to their cognitive status. This result could have important clinical implications.
Methyl group metabolism gene polymorphisms and susceptibility to prostatic carcinoma

Alterations of DNA methylation are very frequent in prostatic carcinoma. A possible cause underlying altered DNA methylation could be an insufficient level of S‐adenosylmethionine as a consequence of nutritional imbalances or of weaker alleles of genes for its synthesis, i.e., encoding methylene‐tetrahydrofolate reductase (MTHFR), methionine synthase (MS), and β‐cystathione synthetase (CBS). Therefore, homozygosity or heterozygosity for such weaker alleles may underlie susceptibility to prostatic carcinoma.
Spin manifolds, Einstein metrics, and differential topology

We show that there exist smooth, simply connected, fourdimensional spin manifolds which do not admit Einstein metrics, but nevertheless satisfy the strict Hitchin-Thorpe inequality. Our construction makes use of the Bauer/Furuta cohomotopy re nement of the Seiberg-Witten invariant [4, 3], in conjunction with curvature estimates previously proved by the second author [17]. These methods also easily allow one to construct examples of topological 4-manifolds which admit an Einstein metric for one smooth structure, but which have in nitely many other smooth structures for which no Einstein metric can exist.
Issue Forum: Can we Enhance People's Lives?

Ours is a voluntary walk of life. A person can fall into being a store manager or broker, but not a professor. We must choose it, aim at it, and persist in it for many years. This highlights the importance of our personal motivations, matters that are systematically omitted from our research reports and CV’s. Some of us come to this profession for no more reason than that it is intellectually engaging. But many choose this path (or hold to it) because it offers the chance of helping people, individually or in groups. This motivation can vary from radical activism at one extreme to quiet supportiveness on the other. We hope, of course, that we are improving the lives of the students we teach. Some aim to do this with their research as well. This forum is concerned with what some would regard as a primary goal of research in communication*the chance that our theories and investigations can help people have better lives. This might be reflected in their relational satisfactions, their emotional or physical health, the opportunity to find peace in a challenging moment, or some other private benefit. This Forum’s four contributing scholars are each notable for having done work that is simultaneously recognized as being both theoretically advanced and immediately beneficial. The three essays of course began with the writers’ own work, but insistently expanded to more general matters. Can we develop procedures that will reliably improve the quality of other people’s lives? Can we extend emotional resources to people who need them? Can we learn to control our angry verbal impulses? The papers have value not only for their answers to these particular questions, but also as exemplars of work that has been self-consciously directed at improving the lives of people outside the academy.
Why Do I Feel Valued and Why Do I Contribute? A Relational Approach to Employee's Organization‐Based Self‐Esteem and Job Performance

Drawing on the relational perspective and self‐consistency theory, we theorize how relationships involving work‐centric, off‐work‐centric, and/or personal components can affect an employee's organization‐based self‐esteem and job performance in Chinese organizational contexts. Matched data were collected from a multi‐source sample that included 219 employee–supervisor dyads from a Chinese bank. Results based on hierarchical regression analyses reveal that a high‐quality relationship with a supervisor through work and off‐work domains (leader–member exchange and guanxi) is positively related to organization‐based self‐esteem. Organization‐based self‐esteem plays a mediating role in the relationship between guanxi and job performance. Additionally, career mentoring from a supervisor (a work‐centric relationship involving personal components) moderates the relationship between organization‐based self‐esteem and job performance.

Visually Interacting with k-medoid-based Algorithms ?

Although database management systems supply basic tools to data recovery and analysis through standard transactions in large amounts of data, the analysis of these data in high dimensional spaces is an overwhelming job. On the other hand, human beings have a great capacity to quickly absorb and understand information presented in graphical form. As data clustering is one of the key techniques in the KDD process, this work aims to use the human visual perception to help in the iterative clustering analysis done by the k-medoid-based algorithms. Our technique takes advantages of the interpretation obtained from the user, through his interaction with the presented visualizations, and allows subsequent data analysis tasks to use these results automatically.
Graph theoretic approach for analysing the readiness of an organisation for adapting lean thinking

Purpose – A literature review revealed that in recent times, many companies have attempted organization‐wide change management through the philosophy and principles of Lean Thinking (LT). Although some organizations have transformed and reaped significant benefits in this endeavour, many organizations have failed in this attempt. One of the reasons can be attributed to the fact that not many organizations are attempting to “assess the organizational readiness” before implementing/adapting LT. This paper aims to address this issue.Design/methodology/approach – Hence in this paper, an attempt has made to address this problem by presenting a hypothetical case study of an Indian organization to comprehensively assess organizational readiness of the case organisation using a graph theoretic approach (GTA), which has the ability to integrate and model multiple inter‐related factors.Findings – From the obtained results, it was found that the case organization is not fully ready to embrace LT. It needs to work on.
Orbital metastasis from hepatocellular carcinoma.

A 70 year-old woman with personal history of hepatitis C virus compensated cirrhosis. Three years before she was diagnosed with HCC in segment VI of the right hepatic lobe. She was first treated with radiofrequency and then she required three sessions of adriamycin-lipiodol transarterial chemoembolization. The computed tomography (CT) practiced four months later revealed a 38 mm hypodense lesion in segment VI, without radiological evidence of tumor activity. The patient presented with four weeks of occasional diplopia and right proptosis. Physical examination showed exophthalmos, conjunctival hyperemia and limited lateral mobilization of the right eye with normal visual acuity. Orbital CT after intravenous contrast revealed a solid, well-defined, hyperdense lesion, located in the right temporal fossa, which destroyed the greater wing of the right zygomatic bone and the ipsilateral orbital wall, penetrating the orbit and displacing anteriorly the lateral rectus muscle and the eyeball. The administration of contrast showed an increase in density of 20 HU and the presence of a nutrient vessel dependent of the ipsilateral carotid artery. This finding was confirmed by magnetic resonance imaging (MRI). Biopsy was performed through an incision in the superior sulcus, and the histological examination revealed the presence of tumor cells with an immunohistochemistry consistent with metastasis from a hepatocellular carcinoma. Tc-99m scintigraphy was performed, showing osteogenic response in right orbital region, consistent with secondary deposit. At follow-up, the patient referred significant pain in right orbital and therefore she received palliative radiotherapy. Four months later, after ten sessions of radiotherapy the patient is still alive with adequate pain control but a limited daily life (ECOG 3).
Massively Multiplayer Online Role-Playing Games: Problematic Use

ABSTRACT Massively Multiplayer Online Role-Playing Games: Problematic Use by Andrew M. Byrne April 2013 Director: Shari M. Sias Department of Addictions and Rehabilitation Studies Massively Multiplayer Online Role Playing Games (MMORPGs) are a form of mass media with potential for behavioral addiction among some users. In past literature on internet addiction MMORPG users have been included alongside other internet users. The outcomes of MMORPG participation usage frequency and demographics have not been adequately analyzed apart from users of other internet-based functions. Screening instruments developed for internet addiction have not been validated on MMORPG users. This study addressed the lack of screening research on MMORPG users using the Internet Addiction Test (IAT) the most used screening instrument for this media. It also explored demographic and frequency traits on a robust sample of MMORPG users. The population sampled was 5313 users of the MMORPG World of Warcraft. Three research questions resulted from the literature search: an exploratory factor analysis demographic and frequency exploration and face validity. The first research question asked "What is the factor structure for the IAT when administered to a sample of MMORPG internet users? " The exploratory factor analysis yielded a two-factor oblique factor structure which included 18 of the original 20 IAT questions. The second research question asked "What is the relationship of demographic variables (age race gender weekly playing/gaming and length of experience playing/gaming) to the final IAT score? " Weak and moderate main effects on IAT score were found for age and weekly hours playing. The third research question asked "What is the relationship between score severity as reported by the IAT and respondents' impressions on whether they identify themselves as `addicted to MMORPGs'? " The IAT was found to be predictive of respondent perceptions of addiction. This research was the first to explore a factor structure for MMORPG users on a behavioral addiction instrument and among the largest validation studies on the IAT in English. The results were conceptualized through Uses and Gratifications theory as unique user media choices and consistent with elements of behavioral addiction. The results also provided a distinct profile for MMORPG users. This research demonstrated the importance to counselors and counselor educators of robust sampling of homogeneous media user groups and individualized screening for addiction.
Improving the Prediction Accuracy of Gene Structures in Eukaryotic DNA with Low C + G Contents

have developed a gene prediction program GeneKey. When trained with the widely used dataset lected by Kulp and Reese, GeneKey can achieve high prediction accuracy for genes with derate and high C+G contents. However, the prediction accuracy is much lower for CG-poor es. To tackle this problem, we construct a new LCG316 dataset composed of gene sequences h low C+G contents. For CG-poor genes, the prediction accuracy of GeneKey when trained with G316 dataset has been improved prominently. Further statistical analysis demonstrates that some cture features, such as splicing signals and codon usage, of CG-poor genes are quite different m that of CG-rich ones. The combination of the two datasets enables GeneKey to get high and anced prediction accuracy for both CG-rich and CG-poor genes. The results of this work imply t careful construction of training dataset is very important for improving the performance of ious prediction tasks. The GeneKey program is available at http://infosci.hust. edu.cn. ywords: DNA sequence, prediction of gene structure, prediction of protein coding region
Policing the police service

Recently public interest in the police service in Australia has emanated from extensive media coverage and from rising public accountability expectations. In light of this, the current paper explores how far the accounting, accountability and performance management systems within “new public management” ideals have evolved within the Australian police services. More specifically, it explores the accountability framework, information for performance evaluation and public sector reform implications for an Australian state police service as a whole, and an individual police station, in particular. The findings suggest that the police service in Australia has a rigid accountability structure and is continuously subject to performance evaluations. Further, it has been found that there is considerable rise of “new public management” ideals within the police services in Australia. It was apparent that the reforms in the police service had a dual purpose – legitimizing the police service to the electorate and ordinary citizens, while encouraging efficiencies of resource use.
Reasoning From Fossils: Learning from the Local Black Hole Population about the Evolution of Quasars

We discuss a simple working scenario for the growth of supermassive black holes (BHs) at the center of spheroidal stellar systems. In particular, we assess the hypotheses that (1) star formation in spheroids and BH fueling are proportional to one another, and (2) the BH accretion luminosity stays near the Eddington limit during luminous quasar phases. With the aid of this simple picture, we are able to interpret many properties of the QSO luminosity function, including the puzzling steep decline of the characteristic luminosity from redshift z ≈ 2 to z = 0: indeed the residual star formation in spheroidal systems is today limited to a small number of bulges, characterized by stellar velocity dispersions a factor of 2-3 smaller than those of the elliptical galaxies hosting QSOs at z ≳ 2. A simple consequence of our hypotheses is that the redshift evolution of the QSO emissivity and of the star formation history in spheroids should be roughly parallel. We find this result to be broadly consistent with our knowledge of the evolution of both the global star formation rate and the QSO emissivity, but we identify interesting discrepancies at both low and high redshifts, to which we offer tentative solutions. Our hypotheses allow us to present a robust method to derive the duty cycle of QSO activity, based on the observed QSO luminosity function and the present-day relation between the masses of supermassive BHs and those of their spheroidal host stellar systems. The duty cycle is found to be substantially less than unity, with characteristic values in the range (3-6) × 10-3, and we compute that the average bolometric radiative efficiency is ϵ ≈ 0.07. Finally, we find that the growth in mass of individual BHs at high redshift (z ≳ 2) can be dominated by mergers and is therefore not necessarily limited by accretion.
Researching into English for research publication purposes from an applied crosscultural perspective

Spanish scholars have begun requesting courses in skills relevant to publishing in English in order to enhance their chances of seeing their work accepted by international journals. I argue that it would be pedagogically useful to include tasks to raise their awareness of English-Spanish crosscultural variation in academic writing. To support this, more crosscultural research into academic discourses in English and Spanish using rigorous comparative designs is still necessary. After reviewing previous crosscultural studies, I suggest some features of methodology and research design that would allow us to yield increasingly comparable, reliable and explanatory findings on which practical teaching applications could usefully draw.
