Exploring the success factors of health information service adoption

Diffusion of electronic services in the medical industry has gather speed with the help of recent developments in the information and communication technologies. Health information service is one of these services that deal with repository, retrieval and make use of medical information in order to improve service quality and reduce cost. Users - including medical staff, administrative staff and patients - of these systems cannot benefit them in a full capacity unless using them comfortably. Behavior of these adopters is affected by various factors related to both of the technology characteristics, user characteristics, social environment and organizational environment in the adoption process. This research will evaluate determinants of health information service adoption among users and analyze relationship of these determinants with the behavior of the user. Moreover, taxonomy about factors that affect technology usage in medical industry will be developed at the end of the study.
Human cyclins A and B1 are differentially located in the cell and undergo cell cycle-dependent nuclear transport

We have used immunofluorescence staining to study the subcellular distribution of cyclin A and B1 during the somatic cell cycle. In both primary human fibroblasts and in epithelial tumor cells, we find that cyclin A is predominantly nuclear from S phase onwards. Cyclin A may associated with condensing chromosomes in prophase, but is not associated with condensed chromosomes in metaphase. By contrast, cyclin B1 accumulates in the cytoplasm of interphase cells and only enters the nucleus at the beginning of mitosis, before nuclear lamina breakdown. In mitotic cells, cyclin B1 associates with condensed chromosomes in prophase and metaphase, and with the mitotic apparatus. Cyclin A is degraded during metaphase and cyclin B1 is precipitously destroyed at the metaphase----anaphase transition. Cell fractionation and immunoprecipitation studies showed that both cyclin A and cyclin B1 are associated with PSTAIRE-containing proteins. The nuclear, but not the cytoplasmic form, of cyclin A is associated with a 33-kD PSTAIRE- containing protein. Cyclin B1 is associated with p34cdc2 in the cytoplasm. Thus we propose that the different localization of cyclin A and cyclin B1 in the cell cycle could be the means by which the two types of mitotic cyclin confer substrate specificity upon their associated PSTAIRE-containing protein kinase subunit.
MR Imaging of Metronidazole-Induced Encephalopathy: Lesion Distribution and Diffusion-Weighted Imaging Findings

BACKGROUND AND PURPOSE: MR imaging features of metronidazole-induced encephalopathy (MIE) have not been fully established. This study was undertaken to determine the topographic distributions and diffusion-weighted imaging (DWI) findings of MIE. MATERIALS AND METHODS: We retrospectively evaluated the initial MR images (n = 7), including DWI (n = 5), and follow-up MR images (n = 4) after drug discontinuation in 7 patents with clinically diagnosed MIE. The topographic distributions of lesions were evaluated on MR images, and DWI signal intensities and apparent diffusion coefficient (ADC) values of the lesions were assessed. RESULTS: MR images demonstrated bilateral symmetric T2 hyperintense lesions in the cerebellar dentate nucleus (n = 7), midbrain (n = 7), dorsal pons (n = 6), medulla (n = 4), corpus callosum (n = 4), and cerebral white matter (n = 1). Brain stem lesions involved the following: tectum (n = 5), tegmentum (n = 4), red nucleus (n = 3) of the midbrain, vestibular nucleus (n = 6), and a focal tegmental lesion involving the superior olivary nucleus (n = 6) and abducens nucleus (n = 4) of the pons and vestibular nucleus (n = 4) and inferior olivary nucleus (n = 1) of the medulla. DWI (n = 5) showed isointensity or hyperintensity of lesions, and the decreased ADC value was found only in the corpus callosum lesions (n = 2). All detected lesions were completely reversible at follow-up except for the single corpus callosum lesion with an initial low ADC value. CONCLUSION: Brain lesions were typically located at the cerebellar dentate nucleus, midbrain, dorsal pons, medulla, and splenium of the corpus callosum. According to DWI, most of the lesions in MIE probably corresponded to areas of vasogenic edema, whereas only some of them, located in the corpus callosum, corresponded to cytotoxic edema.
Gangsters Without Borders: An Ethnography of a Salvadoran Street Gang

Youth gangs have become a tricky subject for sociologists and anthropologists now that we define our research in terms of solidarity with the oppressed. Gang youth certainly are marginalized, and at least some of their bad press is exaggerated. They are also victims of our current economic order. So is widespread apprehension about youth gangs a moral panic? Are they actually scapegoats, symbolic villains for popular anger that should be directed against elites and their power structures? Or are gang youth so dangerous to themselves and everyone else that they need to be suppressed? This is an important question in El Salvador, Guatemala and Honduras where homicide rates have skyrocketed, youth gangs seem to be part of the problem, and out-ofcontrol street crime has become a vote-getter for conservative politicians. No gang is more demonized than Mara Salvatrucha (aka MS-13). On more than one occasion Salvatruchans have massacred bus passengers in El Salvador and Honduras. They are also famous for tattooing their faces and worshipping Satan. The organization is customarily traced to Salvadorans who escaped the civil war in their country by coming to the United States. In inner city Los Angeles, Salvadoran youth had to protect themselves from black and Latino gangs; when U.S. courts deported them, they spread Los Angeles gang culture to San Salvador and other poorly policed Central American capitals. So goes the usual story, but participant-observation research in this realm is rare and I’ve never seen anything on MS-13. Now we have T. W. Ward’s Gangsters Without Borders, based on eight and a half years (1993-2001) experience with MS-13 cliques in Los Angeles and another decade of follow-up.

Commentary response: Addressing the challenges – response to the commentary of Jarrold and Hall (2012)

We thank the Editors for this opportunity to respond to the commentary by Jarrold and Hall (2012) on our article describing the impact of attention deficit/ hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) both individually and in combination on various aspects of memory functioning (Rhodes et al., 2012). This was the first study to provide a detailed investigation of memory functioning in ODD and is notable for having identified that ODD, even in the absence of ADHD or other psychopathology, is associated with significant and wide ranging disruption of both executive and nonexecutive aspects of short term working memory and in long term memory functioning. We were also able to replicate findings from our previous studies (Rhodes et al., 2005 Rhodes et al., 2004) and those of others (Martinussen et al., 2005) that ADHD is also associated with significant executive and non-executive deficits in short term memory and deficits in longer term recognition memory. An additional, and interesting finding was that whilst those with ADHD, when compared to healthy controls, were only impaired on spatial memory tasks, the ODD group demonstrated deficits in both verbal and spatial aspects of memory. Whilst the findings for ODD are new, those for ADHD again replicate those previously described by others (Willcutt et al., 2005). Interestingly these deficits appear to be additive in nature with the comorbid group (ADHD + ODD) representing a hybrid of the two disorders. As pointed out by Jarrold and Hall, we adopted a theoretically driven approach to our analyses. By using a confirmatory rather than exploratory approach to factor analysis we were able to derive theoretically relevant factors that could then be used to examine the differential functioning between the clinical groups and the healthy controls.

Cyc: toward programs with common sense

Cyc is a bold attempt to assemble a massive knowledge base (on the order of 108 axioms) spanning human consensus knowledge. This article examines the need for such an undertaking and reviews the authos' efforts over the past five years to begin its construction. The methodology and history of the project are briefly discussed, followed by a more developed treatment of the current state of the representation language used (epistemological level), techniques for efficient inferencing and default reasoning (heuristic level), and the content and organization of the knowledge base.
MITOSCISSOR: A Useful Tool for Auto-Assembly of Mitogenomic Datasets in the Evolutionary Analysis of Fishes

As a result of the development of rapid and efficient sequencing technologies, complete sequences of numerous mitochondrial genomes are now available. Mitochondrial genomes have been widely used to evaluate relationships between species in several fields, including evolutionary and population genetics, as well as in forensic identification and in the study of mitochondrial diseases in humans. However, the creation of mitochondrial genomes is extremely time consuming. In this paper, we present a new tool, MITOSCISSOR, which is a rapid method for parsing and formatting dozens of complete mitochondrial genome sequences. With the aid of MITOSCISSOR, complete mitochondrial genome sequences of 103 species from Tetraodontiformes (a difficult-to-classify order of fish) were easily parsed and formatted. It typically takes several days to produce similar results when relying upon manual editing. This tool could open the . gb file of Genbank directly and help us to use existing mitogenomic data. In the present study, we established the first clear and robust molecular phylogeny of 103 tetraodontiform fishes, a goal that has long eluded ichthyologists. MITOSCISSOR greatly increases the efficiency with which DNA data files can be parsed and annotated, and thus has the potential to greatly facilitate evolutionary analysis using mitogenomic data.

Joint Source and Channel Coding using Punctured Ring Convolutional Coded CPM

In this paper, a novel trellis source encoding scheme based on punctured ring convolutional codes is presented. Joint source and channel coding (JSCC) using trellis coded continuous phase modulation (CPM) with punctured convolutional codes over rings is investigated. The channels considered are the additive white gaussian noise (AWGN) channel and the Rayleigh fading channel. Optimal soft decoding for the proposed JSCC scheme is studied. The soft decoder is based on the a posteriori probability (APP) algorithm for trellis coded CPM with punctured ring convolutional codes. It is shown that these systems with soft decoding outperform the same systems with hard decoding especially when the systems operate at low to medium signal-to-noise ratio (SNR). Furthermore, adaptive JSCC approaches based on the proposed source coding scheme are investigated. Compared with JSCC schemes with fixed source coding rates, the proposed adaptive approaches can achieve much better performance in the high SNR region. The novelties of this work are the development of a trellis source encoding method based on punctured ring convolutional codes, the use of a soft decoder, the APP algorithm for the combined systems and the adaptive approaches to the JSCC problem.
Vasa recta pericyte density is negatively associated with vascular congestion in the renal medulla following ischemia reperfusion in rats.

Recent evidence suggests that a greater density of pericytes in renal cadaveric allografts is associated with better recovery following transplant. The physiological mechanism(s) through which pericyte density may be beneficial is not well understood. The goal of this study was to test the hypothesis that lower medullary pericyte density is associated with greater renal injury following ischemia reperfusion (IR) in a rat model, providing a basis for future studies to better understand pericytes in a pathological environment. To test our hypothesis, we determined the association between medullary pericyte density and renal injury in spontaneously hypertensive rats (SHR) following 45 min of warm bilateral IR. We found that there was a significant negative relationship between pericyte density and plasma creatinine (slope = -0.03, P = 0.02) and blood urea nitrogen (slope = -0.5, P = 0.01) in female but not male SHR. Pericyte density was negatively associated with medullary peritubular capillary (PT) congestion in both sexes following IR (male: slope = -0.04, P = 0.009; female: slope = -0.03, P = 0.0001). To further test this relationship, we used a previously reported method to reduce pericyte density in SHR. Medullary erythrocyte congestion in vasa recta (VR) and PT significantly increased following IR in both sexes when pericyte density was pharmacologically decreased (VR: P = 0.03; PT: P = 0.03). Our data support the hypothesis that pericyte density is negatively associated with the development of IR injury in SHR, which may be mediated by erythrocyte congestion in the medullary vasculature.
Factorized variational approximations for acoustic multi source localization

Estimation based on received signal strength (RSS) is crucial in sensor networks for sensor localization, target tracking, etc. In this paper, we present a Gaussian approximation of the Chi distribution that is applicable to general RSS source localization problems in sensor networks. Using our Gaussian approximation, we provide a factorized variational Bayes (VB) approximation to the location and power posterior of multiple sources using a sensor network. When the source signal and the sensor noise have uncorrelated Gaussian distributions, we demonstrate that the envelope of the sensor output can be accurately modeled with a multiplicative Gaussian noise model. In turn, our factorized VB approximations decrease the computational complexity and provide computational robustness as the number of targets increases. Simulations are provided to demonstrate the effectiveness of the proposed approximations.
Coupled Aquifer‐Borehole Simulation

A model coupling fluid hydraulics in a borehole with fluid flow in an aquifer is developed in this paper. Conservation of momentum is used to create a one‐dimensional steady‐state model of vertical flow in an open borehole combined with radially symmetric flow in an aquifer and with inflow to the well through the wellbore screen. Both laminar and turbulent wellbore conditions are treated. The influence of inflow through the wellbore screen on vertical flow in the wellbore is included, using a relation developed by Siwoń (1987) . The influence of inflow reduces the predicted vertical variation in head up to 15% compared to a calculation of head losses due to fluid acceleration and the conventional Colebrook‐White formulation of friction losses in a circular pipe. The wellbore flow model is embedded into the MODFLOW‐2000 ground water flow code. The nonlinear conservation of momentum equations are iteratively linearized to calculate the conductance terms for vertical flow in the wellbore. The resulting simulations agree favorably with previously published results when the model is adjusted to meet the assumptions of the previous coupled models.

Aurones have a limited occurrence − thefirst aurone was discovered only in 1943 and, because ofthe limited methods of synthesis [1,3], aurones havereceived very limited attention. Analogy with flavonoidssuggests that aurones could have interesting biologicalproperties [2]. We have already reported that five-membered ringcompounds with a carbonyl group, like tetronic acid [3a],pyrazolone [3b], thiohydanthoin [3c] or indanone [3d],exhibit a high carbon acidity due to the pseudo-planarstructure. These compounds consequently can becondensed easily with aldehydes in the presence of a solidcatalyst (alumina, clay, Al2O3-KF) without solvent (drycondensation). We report herein the extension of this reaction to thesynthesis of 2-arylmethylene-3(2)-naphthofuranones.Naphthofuranone (1), the homologue of 2-coumaranone(2), can be derived from 2-naphthoxyacetic acid (3), anuseful auxin hormone [4]. We are also interested instudying the biological properties of such 3(2)-naphthofuranones described in older literature [5] butpoorly studied to date.
Coronary artery fistula: an abnormality affecting all age groups.

A coronary artery fistula is an abnormal communication between a coronary artery and a cardiac chamber, great vessel, or other vascular structure. It is an infrequent but potentially important abnormality that can affect any age group. Most are congenital in origin, although other etiologies, in particular trauma, have been identified. Many are small and found incidentally during coronary arteriography, while others are identified as the cause of a continuous murmur, myocardial ischemia, congestive heart failure, or, rarely, bacterial endocarditis. The diagnosis should be considered in any patient presenting with a continuous murmur or in the setting of congestive heart failure, myocardial ischemia, or bacterial endocarditis without an obvious etiology. The pathophysiologic mechanisms resulting in symptoms include cardiac volume overload due to the shunting of blood and reduction of the myocardial blood supply due to "coronary steal. " The diagnosis of coronary artery fistula may be suggested by the finding of a continuous murmur in a precordial location, which is atypical for patent ductus arteriosus. Two-dimensional echocardiography may demonstrate dilated coronary arteries, and pulse-wave and color-flow Doppler examinations can display turbulent flow in the suspected fistula and its receiving chamber or vessel. Angiography is generally needed to confirm the diagnosis and elucidate anatomic detail. The natural history of coronary artery fistula is variable, with long periods of stability in some patients and gradual progression of symptoms in others. Small fistulas detected incidentally at the time of angiography do not require immediate surgical correction, but careful follow-up is indicated because the potential for enlargement with physiologically important shunting exists and cannot readily be predicted. Spontaneous closure is uncommon. Surgical repair of the fistula is recommended for symptomatic patients and for some without symptoms because a quantitatively small shunt does not predict freedom from future symptoms or complications. Those selected for medical management must be followed closely.
Understanding repeated actions: Examining factors beyond anxiety in the persistence of compulsions

Two decades of research on obsessive-compulsive disorder (OCD) has helped us develop a strong understanding of why obsessions are often followed by the performance of a compulsive act. What we have understood less well is why that act is repeated, even though it often results in an increase, rather than decrease, in discomfort. Emergent research on compulsive checking implicates a number of beliefs—including perceived responsibility, perceived harm, need for certainty, and beliefs about one’s memory— that may influence behavioural parameters (e.g., check duration) of checking episodes. Furthermore, it has also been suggested that the act of compulsive checking may recur in part because of a self-perpetuating mechanism in which checking has paradoxical effects on these beliefs. Finally, some researchers have proposed that attentional focus (e.g., focus on threat) during checking may be related these paradoxical outcomes. At present, these ideas are mostly speculative, in part because there have been so few detailed studies of the actual phenomenology of compulsive rituals. The purpose of the present research was to gather phenomenological data on compulsions as performed by a clinical sample under ecologically valid conditions. Study 1 extended emergent research suggesting that compulsions may persist because the act of checking has a number of ironic effects on beliefs. Individuals with a diagnosis of obsessive-compulsive disorder (OCD) and anxious controls (AC) completed a naturalistic stove task in our laboratory kitchen. Participants were fitted with portable eyetracking equipment and left on their own to boil a kettle, turn the stove off, and check to ensure that the stove is safe before leaving the kitchen. Surrounding the stove were household items that are “threatening” (e.g., matches) or “non-threatening” (e.g., mugs). Ratings of mood, responsibility, harm (severity, probability) and memory confidence were taken pre- and post-task and a portable eyetracker was used to monitor attention throughout the stove task. We examined the relations between behavioural indices (check duration, attentional focus) and pre- and post-task ratings of responsibility, perceived harm, mood, and memory confidence. Although we found that OCD (as compared to AC) participants took significantly longer to leave the kitchen after using the stove, we found no evidence that stronger pre-task ratings of responsibility, perceived harm, or memory confidence were associated with longer check duration. However, we found some evidence of an ironic effect whereby greater check duration was associated with greater perceived harm and decreased certainty about having properly ensured the stove was off. Of note, these ironic effects were not unique to participants with OCD, but were also observed in the AC group. With respect to the eyetracking data, we found minimal evidence linking threat fixations and beliefs in participants with OCD. In contrast, a number of interesting relations emerged in the eyetracking data of our anxious control…
Low-complexity face recognition using contour-based binary descriptor

Face recognition has become a popular topic due to its applications in security, surveillance and so on. Current local methods such as the local binary pattern (LBP) or local derivative pattern (LDP) perform better than holistic methods since they are more stable on local changes such as misalignment, expression or occlusion, but their high computational complexity limit their applications. While LBP is a good feature method, the scale invariant feature transform (SIFT) is widely accepted as one of the best features to capture edge or local shape information. However, SIFT-based schemes are sensitive to illumination variation. Thus, the authors propose an LBP edge-mapped descriptor that uses maxima of gradient magnitude points. It accurately illustrates facial contours and has low computational complexity. Under variable lighting, experimental results show that the authors' method has a 16.5% higher recognition rate and requires 9.06 times less execution time than SIFT under FERET fc. Besides, when applied to the Extended Yale Face Database B, the authors' method outperformed SIFT-based approaches as well as saving about 70.9% in execution time. In uncontrolled conditions, their method has a 0.82% higher recognition rate than LDP histogram sequences in the Unconstrained Facial Images database.
