Attitude Predictability and Helpfulness in Online Reviews: The Role of Explained Actions and Reactions

This article examines explanation type in online word of mouth (WOM), focusing on what individuals explain: their actions ("I chose this product because …") or their reactions ("I love this product because …"). Results show that review writers explain their actions more than their reactions for utilitarian products, but they explain their reactions more than their actions for hedonic products. They do so to be helpful to review readers, who find explained actions more helpful for utilitarian products and explained reactions more helpful for hedonic products. Explained actions and reactions are differentially helpful across product type because they increase readers’ ability to predict their attitude toward the reviewed product: explained actions increase attitude predictability for utilitarian products, whereas explained reactions increase attitude predictability for hedonic products. These increases in attitude predictability and review helpfulness ultimately increase readers’ choice of the product in question. This article contributes to the explaining and the WOM literatures by focusing on what individuals explain, rather than on how they explain, by identifying product type as a novel moderator of what review writers explain (actions or reactions), and by examining when and why review readers prefer different types of explanations.
Build Order Optimization in StarCraft

In recent years, real-time strategy (RTS) games have gained interest in the AI research community for their multitude of challenging subproblems — such as collaborative pathfinding, effective resource allocation and unit targeting, to name a few. In this paper we consider the build order problem in RTS games in which we need to find concurrent action sequences that, constrained by unit dependencies and resource availability, create a certain number of units and structures in the shortest possible time span. We present abstractions and heuristics that speed up the search for approximative solutions considerably in the game of StarCraft, and show the efficacy of our method by comparing its real-time performance with that of professional StarCraft players.
The frontier of data discoverability: Why we need to share our data1

We are now in an era where sharing and making data widely accessible are not only expected within many disciplines, but also required by federal granting agencies and many scientific journals. In addition, there are practical reasons why authors should deposit their data into permanent data repositories: (1) it prevents data loss due to accidents, theft, or death of the researcher; (2) it enables published research to be reproduced by others; (3) publications associated with accessible data sets can have higher citation rates; (4) deposited data sets are increasingly recognized for scholarly recognition and professional advancement; and (5) stored and accessible data can be used in the future for projects that are unanticipated today. Applications in Plant Sciences requires that data underlying its articles be publicly accessible as a condition of publication to promote the continued advancement of the field of plant biology.
Bridging the gap between simulation and experimental evaluation in computer networks

Simulation and experimentation are two complementary techniques for performance evaluation, each one of them having opposite characteristics and advantages. While one allows total control and abstraction in the experiment, the other provides greater detail and realism. Though ideally it would be desirable to perform both, it is hard to direct the required efforts to develop a performance evaluation twice, once over a simulator and then again on a real network. In this paper, a new approach is explored through a tool called Simmcast testbed, which allows one to execute, from a single codebase, experiments both in simulation and experimentation mode. A didactic example is discussed in detail, and the correlation of the simulated and experimental results is presented.
Water, water, everywhere: sodium and water balance and the injured brain

Purpose of review This review focuses on water shift and oedema in acute brain injury, with particular aspects on pathophysiology of water movements, the role of aquaporins and the potential of new therapies. This review reports on update of both significant experimental and clinical findings on factors implicated in oedema formation. Recent findings The main inputs came from the demonstrated role of aquaporins (especially AQP4) in brain oedema control. The absence of aquaporin agonist or antagonist does not help to clarify the net effect of aquaporins on brain oedema. The clinical practice of osmotherapy, especially with hypertonic saline failed to improve neurological outcome in a large randomized clinical trial. Colloid treatment was not proven efficient and potentially dangerous. Some hopes might come from targeting inflammatory cascade and neurogenic mediators to reduce lesion severity and to limit the blood–brain barrier dysrupture. Summary Water content control and partition can be better assessed in clinic with NMR helping to make decisions, but with limited proven therapies. The timing for such interventions might be crucial and future biomarkers might be very helpful.
Disorders of binocular convergent fusion and stereoscopic space perception following acquired brain damage : treatment and neuroanatomical implications

III ABSTRACT The unified and three-dimensional percept we perceive through the two of our eyes is the result of multiple interacting functional and neural processing stages in the visual brain. They range from convergence eye movements and sensory merging of the two disparate monocular images (binocular convergent fusion) up to an elaborated stereoscopic percept containing spatial depth (stereoscopic vision). Acquired disorders of binocular convergent fusion and stereoscopic vision of varying degrees are frequent sequels following damage to the brain, e.g. after a stroke or traumatic injury, among others. Typical symptoms of fusion impairment are blurred vision and/or diplopia after short periods of sustained binocular near space activities like reading or PC-work, usually accompanied by asthenopic symptoms like fatigue or eye pressure. Since fusion is a prerequisite of stereoscopic vision, difficulties in tasks that require precise judgements in visuo-spatial depth like grasping or taking staircases can occur. As a result, fusion impairment and associated deficits in stereoscopic vision can result in plain difficulties in almost all visual near-space activities of daily or vocational routines. The probably most severe deficit in stereoscopic vision can manifest in a complete failure to process or integrate any visual depth cues from the monocular images provided by our eyes resulting in a completely " flat " visual world (" flat vision "). In the context of the constantly aging population alongside with an increased number of survivors from brain damage requiring reintegration in daily-and work-life, it appears unexpected, that no systematically evaluated treatment options have been available for these conditions so far. This circumstance surprises even more with regard to neurorehabilitation techniques in other visual domains, as there exist well-evaluated restitutional treatment strategies using perceptual (re-)learning paradigms grounding on repetitive systematic visual practice. Consequently, the principal objective of this thesis was to evaluate in three consecutive studies the effectiveness of a novel binocular vision treatment designed for patients with acquired binocular convergent fusion and stereovision impairments of differential etiology: Study 1 and Study 2 addressed the potential effects of this treatment in three different patient groups with impairments in convergent fusion and stereoscopic vision after cerebral hypoxia (Study 1), stroke and traumatic brain injury (Study 2). It was examined whether repetitive and ABSTRACT IV graded training of binocular convergent fusion with dichoptic devices could lead to improvements in binocular fusion and stereoscopic vision and to which extent the possible benefits might transfer to functionally relevant binocular …
Dysarthric speech database for universal access research

This paper describes a database of dysarthric speech produced by 19 speakers with cerebral palsy. Speech materials consist of 765 isolated words per speaker: 300 distinct uncommon words and 3 repetitions of digits, computer commands, radio alphabet and common words. Data is recorded through an 8-microphone array and one digital video camera. Our database provides a fundamental resource for automatic speech recognition development for people with neuromotor disability. Research on articulation errors in dysarthria will benefit clinical treatments and contribute to our knowledge of neuromotor mechanisms in speech production. Data files are available via secure ftp upon request.
Artefacts malléables et perméables (AMP) pour mener des activités pédagogiques

Nous presentons ici differentes experimentations montrant la difficulte pour des utilisateurs finaux (enseignants et apprenants) de s’approprier la malleabilite d’un dispositif numerique de formation dans un cadre reel. Cette appropriation est facilitee si l’on definit ce dispositif dans le cadre elargi du Web 2.0, comme un agglomerat de Blogs heteroclites, eux-memes agglomerant diverses fonctionnalites du Web 2.0. L'artefact que nous avons realise, le « Personal Teaching Environment » (PTE) permet l’exploitation pedagogique de cet environnement. Nous analysons cet artefact au moyen d’une enquete qualitative et en le rapprochant de la notion d’heterotopie propre a Michel Foucault. Ce rapprochement eclaire la possibilite d’accompagner la notion de permeabilite des espaces et de porosite des spheres sociales.
Uso de escalas para avaliação da doença de Parkinson em fisioterapia

The Parkinson' disease (PD) is a degenerative illness of the central nervous system, the main features of which are tremor, rigidity and bradykinesia. Therapeutic progress has brought about several clinical scales to assess PD patients, in an attempt to monitor disease development and to evaluate the effectiveness of different treatments. This study aims at reviewing main scales used to assess individuals with PD, discussing their application onto physical therapy practice. Scales found include: Degree of Disability or Hoenn and Yahr Scale; Unified Parkinson's Disease Rating Scale (UPDRS); Webster's PD Rating Scale; Sydney Scale; Northwestern University Disability Scales (NUDS); PD Questionnaire (PDQ-39) and PD Quality of Life (PDQL) ; and Parkinson's Activity Scale (PAS). Webster's scale rates the patient according to the degree of disability; however, its reliability hasn't been attested. Sydney Scale assesses mainly the structural and corporal function levels, while NUDS focuses daily functional activities. The PDQ - 39 and PDQL questionnaires are specifically designed to evaluate patients' perception of their quality of life, me PAS was recently developed based on physical therapy objectives, but so far its reliability has not been established. Both the Hoehn and Yahr and the UPDR scales stand out for their reliability and may be used by physical therapists, allowing for better evaluation of patients' functional status.
Hill-climbing attack to an Eigenface-based face verification system

We use a general hill-climbing attack algorithm based on Bayesian adaption to test the vulnerability of an Eigenface-based approach for face recognition against indirect attacks. The attacking technique uses the scores provided by the matcher to adapt a global distribution, computed from a development set of users, to the local specificities of the client being attacked. The proposed attack is evaluated on an Eigenface-based verification system using the XM2VTS database. The results show a very high efficiency of the hill-climbing algorithm, which successfully bypassed the system for over 85% of the attacked accounts.
Walking the Talk: The Relationship Between Leadership and Communication Competence

Executive Summary This study suggests that communication competence is a prerequisite for effective leadership. One-hundred fifty-one employees of nine organizations rated their immediate supervisor's communication competence and using a three dimensional integrated model of leadership categorized that supervisor's perceived leadership effectiveness. Each of the leadership dimensions, as well as the model as a whole, was highly correlated with competent communication by the supervisor.
Feedback-based gameplay metrics

The application of gameplay metrics to empirically express a player's engagement with the game system has become more appealing to a broader range of researchers beyond the computer sciences. Within game studies, the appropriation and use of gameplay metrics not only further shifts these methods beyond formalized user testing (e.g. with the aim of product improvement) but creates a demand for a more universal approach to game metric extraction that can be applied to a wider range of games and account for different social science research agendas. Set in the context of a study into player experiences with participants aged 14-16 years of age, a method of articulating and identifying key moments of game-play pertinent to an analysis of experience with simulated violence was required [38]. This paper describes a pragmatic solution to the need to study a range of games that were determined not by the researchers but the study's participants. The solution exploits and examines the audio-video feedbacks presented to the player as part of their engagement with a game system. This paper broadly outlines this mode of metric extraction and its application to research that seeks to understand the nature of engagement and player motivations across a mixed methodology approach.
Effects of cyclin D1 gene silencing on cell proliferation, cell cycle, and apoptosis of hepatocellular carcinoma cells

This study aims to investigate the effects of Cyclin D1 silencing on cell cycle, cell proliferation, and apoptosis of hepatocellular carcinoma cells (HCC). Cells were divided into the blank group, negative control group (HCC cells transfected with control shRNA), Cyclin D1 shRNA group (HCC cells transfected with Cyclin D1 shRNA), and the normal group (human normal liver L‐02 cells). Expressions of Cyclin D1, Caspase‐3, Bcl‐2, and C‐myc were detected by RT‐qPCR and Western blotting. Cell proliferation was detected by Cell Counting Kit‐8. Cell cycle and apoptosis were detected by flow cytometry. Tumor xenograft in nude mice was performed to detect in vivo tumorigenesis. HCC tissues and HCC cells exhibited elevated expression levels of Cyclin D1. Cyclin D1 expression levels was found to be correlated with tumor size and tumor staging. Compared with the normal group, the blank group showed enhanced cell proliferation, a reduction in the amount of cells in G0/G1 phase, increased number cells in S and G2/M phase, reduced apoptosis, elevated expressions of Cyclin D1, Bcl‐2, and C‐myc, decreased Caspase‐3 activity and significant tumorigenicity. In comparison with the blank group, the Cyclin D1 shRNA group revealed weakened cell proliferation, reduced cells in S and G2/M phase, increased cells in G0/G1 phase, increased Annexin V positive cell ratio, decreased expression of Cyclin D1, Bcl‐2, and C‐myc, elevated Caspase‐3 activity and inhibited tumorigenicity. In conclusion, Cyclin D1 gene silencing suppresses cell proliferation and inhibits cell apoptosis, which may be a new target approach in the treatment and management for HCC.
Vascular Toxicity of Cocaine

Cocaine acts on the vascular system by a number of mechanisms including monoamine re-uptake inhibition, local anesthesia, anti-cholinergic activity, alpha-adrenergic stimulation, regulation of various vasoconstrictor and vasodi- lator agents and promotion of prothrombotic state. These effects lead to a number of clinical syndromes via vasoconstric- tion, platelet activation, thrombus formation and early atherosclerosis in almost every organ of the body. Many of these effects may be under appreciated. Furthermore, cocaine is commonly associated with the use of tobacco and alcohol which can lead to superadditive effects and/or prolonged toxicity.
Stalking: Psychiatric Perspectives and Practical Approaches.

Stalking: Psychiatric Perspectives and Practical Approaches is edited by Debra A. Pinals, who worked with members of the Committee on Psychiatry and the Law of the Group for the Advancement of Psychiatry (GAP) to conceptualize and prepare the book. The authors’ stated goals include: presenting stalking from several perspectives, identifying and appraising current clinical research about stalking, and providing practical guidance with original commentary. They accomplish the latter goal by including excerpts from the committee’s discussions and reviews of the current stalking literature, along with comments about potential directions for future research. The book is divided into four parts: “Introduction,” “Clinical Aspects of Stalking,” “Stalking and the Law,” and “Special Issues. ” The introduction by Paul Mullen provides an excellent overview of the history of stalking and contemporary clinical questions raised regarding the evaluation of stalkers. Some of the challenges associated with stalking research are arriving at a commonly accepted definition of stalking and establishing a classification system of stalking behavior. This book applies the classification scheme proposed by Mullen and his colleagues, which uses a stalker’s motivation as the primary factor in categorization. Most authors of the chapters are nationally recognized scholars. The chapters by Phillip J. Resnick and James Knoll present clinically useful information about the risk assessment and risk management of stalking. The volume includes chapters that focus on various statutory schemes and forensic evaluations of stalkers. Excellent summaries of stalking in special populations are reviewed in the chapters about stalking among juveniles, cyberstalking, and targeting of celebrities and presidents. Perhaps the most interesting component of the book is the commentary provided by the GAP Committee on Psychiatry and the Law. Their comments are present throughout the book and shed light on the discussions, debates, and conclusions drawn by the committee. One of the book’s weaknesses is the absence of a chapter on clinical treatment of stalkers. Dr. Knoll’s chapter, “Risk Management of Stalking,” provides some guidelines but lacks a comprehensive discussion of the efficacy of biological and psychological treatment as outlined in the scientific literature. In conclusion, Stalking: Psychiatric Perspectives and Practical Approaches is well written and informative. I recommend it to clinicians and forensic evaluators who work with this population. The book is useful as a framework for individuals who treat stalkers, but is not a comprehensive source of treatment methodologies. Book Reviews
Sulfur Fertilization Changes the Community Structure of Rice Root-, and Soil- Associated Bacteria

Under paddy field conditions, biological sulfur oxidation occurs in the oxidized surface soil layer and rhizosphere, in which oxygen leaks from the aerenchyma system of rice plants. In the present study, we examined community shifts in sulfur-oxidizing bacteria associated with the oxidized surface soil layer and rice roots under different sulfur fertilization conditions based on the 16S ribosomal RNA (rRNA) gene in order to explore the existence of oligotrophic sulfur-oxidizing bacteria in the paddy rice ecosystem. Rice plants were grown in pots with no fertilization (control) or CaCO3 or CaSO4 fertilization. A principal-coordinates analysis (PCoA) showed that CaSO4 fertilization markedly affected bacterial communities associated with rice roots and soil, whereas no significant differences were observed in plant growth among the fertilizer treatments examined. In rice roots, the relative abundance of Acidobacteria, Alphaproteobacteria, Gammaproteobacteria, and TM7 was significantly higher in CaSO4-fertilized pots than in control pots. Alphaproteobacteria, Bradyrhizobiaceae, and Methylocystaceae members were significantly more abundant in CaSO4-fertilized roots than in control roots. On the other hand, the abundance of Actinobacteria and Proteobacteria was lower in CaSO4-fertilized soil than in control soil. These results indicate that the bacteria associated with rice roots and soil responded to the sulfur amendment, suggesting that more diverse bacteria are involved in sulfur oxidation in the rice paddy ecosystem than previously considered.
Superconductivity and the quantum hard-core dimer gas.

On discute du systeme de liaisons de valence resonnantes a courte distance realise par un gaz de dimeres a cœur dur quantique de densite arbitraire sur un reseau carre a deux dimensions. Quand les dimeres couvrent completement le reseau, on pense qu'il y a une transition du premier ordre a partir d'un cristal de dimeres vers un etat liquide quantique isolant possedant des excitations de basse energie, neutres et sans spin appelees «resonons». En dessous des densites d'empilement compact, l'etat fondamental est superfluide. En plus du mode habituel en Goldstone, il y a des excitations de basse energie, sans spin de limite de zone
Emotional Risk Factors and Postconcussional Disorder

Emotional risk factors were examined in 129 litigant and nonlitigant patients diagnosed with Postconcussional Disorder (PCD) following Mild Traumatic Brain Injury (MTBI). According to Millon Clinical Multiaxial Inventory (MCMI) criteria, four subgroups emerged: (a) 14.7% met criteria for an Axis I disorder, (b) 24.8% for an Axis II disorder, (c) 24.0% for bout Axis I and II disorders, and (d) 36.4% fell below threshold for psychopathology. Thus, 63.5% endorsed emotional pathology. Of the four groups, those with both Axis I and II psychopathology presented the greatest number of emotional complaints in a clinical interview and manifested the lowest neurocognitive test scores. Motor skills, verbal abilities, memory functioning, and IQ were primarily affected. With the exception of post-morbid emotional complaints, no significant differences were identified between litigants and nonlitigants. Our analysis suggests that the combination of both Axis I and II psychopathology is associated with greater impairment following MTBI.
New Functions for Non-collagenous Domains of Human Collagen Type IV

Collagen type IV is a major component of the basal lamina of blood vessels. Six genetically distinct collagen type IV chains have been identified and are distributed in a tissue-specific manner. Here we define a novel function for soluble non-collagenous (NC1) domains of the α2(IV), α3(IV), and α6(IV) chains of human collagen type IV in the regulation of angiogenesis and tumor growth. These NC1 domains were shown to regulate endothelial cell adhesion and migration by distinct αv and β1integrin-dependent mechanisms. Systemic administration of recombinant α2(IV), α3(IV), and α6(IV) NC1 domains potently inhibit angiogenesis and tumor growth, whereas α1(IV), α4(IV), and α5(IV) showed little if any effect. These findings suggest that specific NC1 domains of collagen type IV may represent an important new class of angiogenesis inhibitors.
