Visual Saliency Detection via Sparsity Pursuit

Saliency mechanism has been considered crucial in the human visual system and helpful to object detection and recognition. This paper addresses a novel feature-based model for visual saliency detection. It consists of two steps: first, using the learned overcomplete sparse bases to represent image patches; and then, estimating saliency information via low-rank and sparsity matrix decomposition. We compare our model with the previous methods on natural images. Experimental results on both natural images and psychological patterns show that our model performs competitively for visual saliency detection task, and suggest the potential application of matrix decomposition and convex optimization for image analysis.
The Liminality of Temporary Agency Work: Exploring the Dimensions of Danish Temporary Agency Workers’ Liminal Experience

The concept of liminality refers to the experience to be betwixt-and-between social structures and the associated positions, statuses, and roles. We advance the original use of the concept by introducing the various meanings that the experience of being in a liminal state can take. Drawing on political anthropology we identify the dimensions of ‘types of subjects,’ ‘time,’ ‘space,’ and ‘scale’ in order to analytically unlock the liminal experience. Exemplifying our concept we present the findings from an own study of temporary agency workers in Denmark. Exploring the workers’ interpretations allows us to illustrate to what extent their employment situation constitutes a multi-dimensional liminal experience between established social structures and employment categories. The article emphasizes the complexity of the liminal experience. Theoretically and empirically, we show the many meanings along which liminality can unfold in organizational and work-related contexts. We argue that future studies should explore the various dimensions in other contexts of passages from one relatively stable state to another. In doing so, similarities and differences between various liminal experiences and the role the various dimensions play could be identified.
Premedication with Granisetron Reduces Shivering during Spinal Anaesthesia in Children

This study evaluates the effect of prophylactic granisetron on the incidence of postoperative shivering after spinal anaesthesia in children. Eighty children, American Society of Anesthesiologists physical status I to II and aged two to five years were scheduled for surgery of the lower limb under spinal anaesthesia. The children were randomised to receive 10 μg/kg granisetron diluted in 10 ml saline 0.9% intravenously (group 1, n=40) or placebo (10 ml 0.9% saline, group 2, n=40) to be given over five minutes just before spinal puncture. Shivering, core temperature and the levels of motor and sensory block were assessed. No patients shivered in group 1. However, six patients shivered in Group 2 (P=0.025). There were no significant differences in the other measured variables between the groups. Granisetron is an effective agent to prevent shivering after spinal anaesthesia in children from two to five years of age.
Automatic discovery of meaningful object parts with latent CRFs

Object recognition is challenging due to high intra-class variability caused, e.g., by articulation, viewpoint changes, and partial occlusion. Successful methods need to strike a balance between being flexible enough to model such variation and discriminative enough to detect objects in cluttered, real world scenes. Motivated by these challenges we propose a latent conditional random field (CRF) based on a flexible assembly of parts. By modeling part labels as hidden nodes and developing an EM algorithm for learning from class labels alone, this new approach enables the automatic discovery of semantically meaningful object part representations. To increase the flexibility and expressiveness of the model, we learn the pairwise structure of the underlying graphical model at the level of object part interactions. Efficient gradient-based techniques are used to estimate the structure of the domain of interest and carried forward to the multi-label or object part case. Our experiments illustrate the meaningfulness of the discovered parts and demonstrate state-of-the-art performance of the approach.
Ownership Structure andthe Performance of Belgian Listed Firms

In this study we investigate empirically the relationship between ownership structure of Belgian listed firms, and their performance measured by Tobin’s Q. We focus on the management and the largest shareholders equity ownership. We use first a cross-sectional estimation from 1991 to 1996. Second, we use panel data estimation to control whether the results found cross-sectionally are not due to unobserved firm heteroeneity. The use of panel data confirms the results obtained cross-sectionally for managerial ownership, that is, the relationship between the fraction of equities held by managers and Tobin’s Q is negative. However, panel data results for the relationship between largest sharholders equities ownership and Tobin’s Q become positive, while it is negative cross-sectionally. These results indicate that there is firm heterogeneity which is not captured in the cross-section estimation.
Young Women Have Poorer Outcomes than Men after Stroke

Background and Purpose: Gender differences in stroke outcome have not been fully assessed in young patients. Methods: We conducted an observational study of consecutive young ischemic stroke patients (≤50 years of age) admitted to a stroke unit (January 1999 to December 2009). Basal data, subtype of ischemic stroke, stroke severity [Canadian Neurological Scale (CNS)], length of hospital stay, inhospital complications, mortality and functional outcome at discharge [modified Rankin Scale (mRS) score] were analyzed. For stroke severity and outcome analyses, 2 age groups were established: 15–30 (very young group) and 31–50 years old (middle-aged young group). Results: A total of 310 patients were enrolled; 128 females and 182 males. The mean age was similar in women and men (41.07 ± 8.6 vs. 42.12 ± 8.2, NS). Migraine was more frequent in women, whereas arterial hypertension, hyperlipidemia, alcohol abuse, current smoking and atherothrombotic infarction were more frequent in men (p < 0.05). Females presented greater stroke severity than men [median CNS (IQR) = 8 (3.5) vs. 9 (2.5), p = 0.014] except in the very young group [median CNS (IQR) = 9 (1.8) vs. 8 (5), p = 0.022]. Female sex was a predictor of unfavorable outcomes (mRS >2) at discharge in the total sample (OR = 3.33; 95% CI = 1.41–7.84) and in the middle-aged young group (OR = 2.62; 95% CI = 1.05–6.53), adjusted by baseline data, stroke subtype, inhospital complications, length of stay and stroke severity. Conclusions: Female gender is associated with worse outcomes in adult ischemic stroke patients up to 50 years old. However, this effect is not observed in younger patients (15–30 years).
Therapy against murine collagen‐induced arthritis with T cell receptor Vβ‐specific antibodies

Immunization with native type II collagen (CII) of susceptible strains of mice (H‐2q) induces a rheumatoid arthritis‐like disease. Collagen‐induced arthritis (CIA) is an experimental model for T cell‐mediated autoimmune disease. To investigate the T cell receptor (TcR) repertoire involved in the pathogenesis of CIA, CII‐primed DBA/1 mice were treated with various TcR VbT‐specific monoclonal antibodies (mAb) using a protocol resulting in a long‐term elimination of the target T cells. In vivo treatment with anti‐CD4 mAb led to nearly complete protection against CIA. Mice injected with anti‐Vβ8. 1,2 or anti‐Vβ5. 1,2 mAb had a reduced incidence of arthritis (respectively 28.6% and 50% vs 84.6% for the control group). Administration of anti‐VbT2 mAb delayed the onset of the disease whereas injection of anti‐VbT6 or anti‐VbT11 mAb did not alter CIA. Moreover, the combined treatment with anti‐VbT2 and anti‐Vβ5 mAb efficiently reduced the development of CIA. The humoral response to CII was down‐regulated only in the groups of mice that were improved by the treatment. In vitro proliferative response to CII of lymph node cells from primed DBA/1 was partially blocked by addition of several anti‐VbT mAb. Thus, our findings suggest that the overall T cell response to CII may be polyclonal while the T cell clones involved in the pathogenesis of CIA express a limited number of Vβ chains.
The Relationship Rights of Children

This book develops a comprehensive and foundational account of children's moral and constitutional rights in connection with state decisions to create or dissolve legal and social relationships between children and adults. The theory creates a framework for critiquing laws governing parentage (paternity, maternity, adoption), custody of children by parents and non-parents, child maltreatment intervention, and termination of parental rights.
Morphogenesis defects are associated with abnormal nervous system regeneration following roboA RNAi in planarians

The process by which the proper pattern is restored to newly formed tissues during metazoan regeneration remains an open question. Here, we provide evidence that the nervous system plays a role in regulating morphogenesis during anterior regeneration in the planarian Schmidtea mediterranea. RNA interference (RNAi) knockdown of a planarian ortholog of the axon-guidance receptor roundabout (robo) leads to unexpected phenotypes during anterior regeneration, including the development of a supernumerary pharynx (the feeding organ of the animal) and the production of ectopic, dorsal outgrowths with cephalic identity. We show that Smed-roboA RNAi knockdown disrupts nervous system structure during cephalic regeneration: the newly regenerated brain and ventral nerve cords do not re-establish proper connections. These neural defects precede, and are correlated with, the development of ectopic structures. We propose that, in the absence of proper connectivity between the cephalic ganglia and the ventral nerve cords, neurally derived signals promote the differentiation of pharyngeal and cephalic structures. Together with previous studies on regeneration in annelids and amphibians, these results suggest a conserved role of the nervous system in pattern formation during blastema-based regeneration.
A Hybrid Algorithm With Artifact Detection Mechanism for Region Filling After Object Removal From a Digital Photograph

This work aims to develop a novel function of the digital camera, i.e., region-filling after object removal from a digital photograph. This problem is defined as how to "guess" the Lacuna region after removal of an object by replicating a part from the remainder of the whole image with visually plausible quality. We propose a hybrid region-filling algorithm composed of a texture synthesis technique and an efficient interpolation method with a refinement approach: 1) the "subpatch texture synthesis technique" can synthesize the Lacuna region with significant accuracy; 2) the "weighted interpolation method" is applied to reduce computation time; and 3) the "artifact detection mechanism" integrates the Kirsch edge detector and color ratio gradients to detect the artifact blocks in the filled region after the first pass of filling the Lacuna region when the result may not be satisfactory. This can lead to resynthesizing the artifact blocks without user intervention and can be compliant to the unsuccessful results of other algorithms. In the procedure of region-filling, color texture distribution analysis is used to choose whether the subpatch texture synthesis technique or the weighted interpolation method should be applied. In the subpatch texture synthesis technique, the actual pixel values of the Lacuna region are synthesized by adaptively sampling from the source region. The experimental results show that our proposed algorithm can achieve a better performance than previous methods. Particularly, the regular computation of our proposed algorithm is more suitable for implementation of the hardware in a digital camera
Reasons Reviewers Reject and Accept Manuscripts: The Strengths and Weaknesses in Medical Education Reports

Purpose Scientific journals rely on peer review to maintain the high quality and standards of papers accepted for publication. The purpose of this study was to explore the strengths and weaknesses of medical education reports by analyzing the ratings and written comments given by external reviewers. Method The author conducted a content analysis of reviewers' comments on 151 research manuscripts submitted to the 1997 and 1998 Research in Medical Education conference proceedings. The negative comments on 123 manuscripts that received “questionable, probably exclude” or “definitely exclude” overall ratings from at least one reviewer were evaluated. A similar analysis was performed on reviewers' positive comments for 28 manuscripts recommended unanimously for acceptance. Results On average, four peers (4.1, SD = 0.97, range = 2–6) reviewed each manuscript. Of those recommended for exclusion, a mean of 2.3 reviewers recommended exclusion and each reviewer wrote a mean of 8.1 (SD = 5.7) reasons. The top ten reasons for rejection were: inappropriate or incomplete statistics; overinterpretation of results; inappropriate or suboptimal instrumentation; sample too small or biased; text difficult to follow; insufficient problem statement; inaccurate or inconsistent data reported; incomplete, inaccurate, or outdated review of the literature; insufficient data presented; and defective tables or figures. The main strengths noted in accepted manuscripts were the importance or timeliness of the problem studies, excellence of writing, and soundness of study design. Conclusion While overstating the results and applying the wrong statistics can be fixed, other problems that the reviewers identified (ignoring the literature, designing poor studies, choosing inappropriate instruments, and writing poor manuscripts) are likely to be fatal flaws warranting rejection.
Particulate matter in new technology diesel exhaust (NTDE) is quantitatively and qualitatively very different from that found in traditional diesel exhaust (TDE).

Diesel exhaust (DE) characteristic of pre-1988 engines is classified as a "probable" human carcinogen (Group 2A) by the International Agency for Research on Cancer (IARC), and the U.S. Environmental Protection Agency has classified DE as "likely to be carcinogenic to humans. " These classifications were based on the large body of health effect studies conducted on DE over the past 30 or so years. However, increasingly stringent U.S. emissions standards (1988-2010) for particulate matter (PM) and nitrogen oxides (NOx) in diesel exhaust have helped stimulate major technological advances in diesel engine technology and diesel fuel/lubricant composition, resulting in the emergence of what has been termed New Technology Diesel Exhaust, or NTDE. NTDE is defined as DE from post-2006 and older retrofit diesel engines that incorporate a variety of technological advancements, including electronic controls, ultra-low-sulfur diesel fuel, oxidation catalysts, and wall-flow diesel particulate filters (DPFs). As discussed in a prior review (T. W. Hesterberg et al.; Environ. Sci. Technol. 2008, 42, 6437-6445), numerous emissions characterization studies have demonstrated marked differences in regulated and unregulated emissions between NTDE and "traditional diesel exhaust" (TDE) from pre-1988 diesel engines. Now there exist even more data demonstrating significant chemical and physical distinctions between the diesel exhaust particulate (DEP) in NTDE versus DEP from pre-2007 diesel technology, and its greater resemblance to particulate emissions from compressed natural gas (CNG) or gasoline engines. Furthermore, preliminary toxicological data suggest that the changes to the physical and chemical composition of NTDE lead to differences in biological responses between NTDE versus TDE exposure. Ongoing studies are expected to address some of the remaining data gaps in the understanding of possible NTDE health effects, but there is now sufficient evidence to conclude that health effects studies of pre-2007 DE likely have little relevance in assessing the potential health risks of NTDE exposures.
Human Immunodeficiency Virus Type 1 Mutations Selected in Patients Failing Efavirenz Combination Therapy

ABSTRACT Efavirenz is a potent and selective nonnucleoside inhibitor of human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT). Nucleotide sequence analyses of the protease and RT genes (coding region for amino acids 1 to 229) of multiple cloned HIV-1 genomes from virus found in the plasma of patients in phase II clinical studies of efavirenz combination therapy were undertaken in order to identify the spectrum of mutations in plasma-borne HIV-1 associated with virological treatment failure. A K103N substitution was the HIV-1 RT gene mutation most frequently observed among plasma samples from patients for whom combination therapy including efavirenz failed, occurring in at least 90% of cases of efavirenz-indinavir or efavirenz-zidovudine (ZDV)-lamivudine (3TC) treatment failure. V108I and P225H mutations were observed frequently, predominantly in viral genomes that also contained other nonnucleoside RT inhibitor (NNRTI) resistance mutations. L100I, K101E, K101Q, Y188H, Y188L, G190S, G190A, and G190E mutations were also observed. V106A, Y181C, and Y188C mutations, which have been associated with high levels of resistance to other NNRTIs, were rare in the patient samples in this study, both before and after exposure to efavirenz. The spectrum of mutations observed in cases of virological treatment failure was similar for patients initially dosed with efavirenz at 200, 400, or 600 mg once a day and for patients treated with efavirenz in combination with indinavir, stavudine, or ZDV-3TC. The proportion of patients carrying NNRTI resistance mutations, usually K103N, increased dramatically at the time of initial viral load rebound in cases of treatment failure after exposure to efavirenz. Viruses with multiple, linked NNRTI mutations, especially K103N-V108I and K103N-P225H double mutants, accumulated more slowly following the emergence of K103N mutant viruses.
Multiple ‘hits’ during postnatal and early adulthood periods disrupt the normal development of sensorimotor gating ability in rats

In the present study, we evaluated a multiple-hit animal model of schizophrenia in an attempt to capture the complex interactions among various adverse developmental factors in schizophrenia. Sprague–Dawley rats were assigned to receive either repeated daily 3-h maternal separation for eight days (first ‘hit’) on postnatal days (PND) 3 to 10, and/or avoidance conditioning for six days (second ‘hit’) on PND 49–56, and/or repeated phencyclidine treatment (third ‘hit’, 3.0 mg/kg, sc) immediately after each daily avoidance conditioning. Prepulse inhibition (PPI) of acoustic startle reflex was assessed at late adolescence (PND 41–43) and early adulthood (PND 62–63). The change in %PPI from the adolescence phase to adulthood phase was used to index the maturation-related improvement of sensorimotor gating ability. Maternal separation, avoidance conditioning and PCP treatment had a complex three-way interaction on the functional improvement of sensorimotor gating. Maternal separation impaired PPI improvement preferentially in the saline rats that were not subjected to avoidance conditioning. Avoidance conditioning had no effect on PPI improvement in the non-maternally separated rats, but restored the maternal separation-induced disruption. However, this restoration effect was abolished by PCP treatment. The present study also identified a number of behavioral, emotional and learning abnormalities caused by these three developmental insults which may precede their interactive disruption of normal development of sensorimotor gating ability.
Enabling school structure, collective responsibility, and a culture of academic optimism : Toward a robust model of school performance in Taiwan

Purpose – The purpose of this research is twofold: to test a theory of academic optimism in Taiwan elementary schools and to expand the theory by adding new variables, collective responsibility and enabling school structure, to the model.Design/methodology/approach – Structural equation modeling was used to test, refine, and expand an organizational path model of student achievement first developed in the USA.Findings – The proposed organizational model was supported in Taiwan and was consistent with the initial studies done in the USA. Further, two concepts were added to the model, enabling structure and collective responsibility, both of which had significant indirect effects on student achievement through academic optimism. Moreover, the theoretical foundations (efficacy, trust, and academic emphasis) of the latent construct of academic optimism were confirmed again in this sample of schools in Taiwan.Originality/value – The findings support an organizational model of student achievement, which has app.
Using Eye-Tracking Procedures to Evaluate Generalization Effects: Practicing Target Words During Repeated Readings Within Versus Across Texts

Abstract. Repeated readings is a frequently studied and recommended intervention for improving reading fluency. Typically, researchers investigate generalization of repeated readings interventions by assessing students' accuracy and rate on researcher-developed high word overlap passages. Unfortunately, this methodology may mask intervention effects given that the dependent measure is reflective of time spent by students reading both practiced and unpracticed words. Eye-tracking procedures have the potential to overcome this limitation. The current study examined the eye movements of participants who were (a) not provided with any intervention (n = 28), (b) provided with repeated readings on a single passage containing a set of target words (n = 28), or (c) provided the opportunity to read four different passages each containing the same set of target words (n = 28). Students' reading of a novel passage containing the target words provides evidence to support recommendations that schools use repeated readings.
Prospective and longitudinal long-term employment outcomes after resective epilepsy surgery

Objective: To investigate long-term employment outcomes after resective epilepsy surgery in a national population-based cohort of adults. Methods: In the Swedish National Epilepsy Surgery Register, all adults who were operated with resective epilepsy surgery from 1995 to 2010 were identified. Two-year follow-up was available for 473/496, 5-year follow-up for 220/240, 10-year follow-up for 240/278, and 15-year follow-up for 85/109 patients. Results: There were no significant changes in employment outcome over time at group level, but for those with full-time employment at baseline, 79%, 79%, 57%, and 47% of seizure-free patients were in full-time work at 2-, 5-, 10-, and 15-year follow-up, compared to patients with benefits at baseline, where 16%, 27%, 31%, and 33% of seizure-free patients worked full time at these time points (p = 0.018 at 10 years). More patients with full-time work had ability to drive, a family of their own, and higher educational status than patients in part-time work or on benefits. Univariate predictors for employment at long term were having employment preoperatively, higher education, favorable seizure outcome, male sex, and younger age at surgery. Multivariate predictors were having employment preoperatively, favorable seizure outcome, and younger age. Conclusions: The best vocational outcomes occurred in seizure-free patients who were employed or students at baseline, which may reflect a higher general psychosocial level of function. Younger age also predicted better employment outcomes and it therefore seems plausible that early referral for surgery could contribute to better vocational outcomes.
