Narcissism assessment in social – personality research : Does the association between narcissism and psychological health result from a confound with self-esteem ?

Influential social and personality psychology research indicates that narcissism is related to psychological health. Such inferences are open to question, however, because they nearly all rely on the same selfreport instrument—the Narcissistic Personality Inventory (NPI; Raskin & Hall, 1979, 1981)—to operationalize and measure narcissism. This is problematic because numerous NPI items do not appear to correspond to common definitions or manifestations of narcissism, and may instead be indicative of selfesteem. Two studies demonstrate that the NPI’s confound with self-esteem accounts for the purported relationship between narcissism and psychological health. This suggests that inferences about narcissism and psychological health may need to be reinterpreted. Results also highlight the need for measures that correspond more directly to core components of narcissism. 2010 Elsevier Inc. All rights reserved.
Two problems in Classical Mechanics

A problem about the present structure of dimensional analysis, and another one about the differences between solids and fluids are suggested. Both problems appear to have certain foundational aspects.
A role for human Dicer in pre-RISC loading of siRNAs

RNA interference is a powerful mechanism for sequence-specific inhibition of gene expression. It is widely known that small interfering RNAs (siRNAs) targeting the same region of a target-messenger RNA can have widely different efficacies. In efforts to better understand the siRNA features that influence knockdown efficiency, we analyzed siRNA interactions with a high-molecular weight complex in whole cell extracts prepared from two different cell lines. Using biochemical tools to study the nature of the complex, our results demonstrate that the primary siRNA-binding protein in the whole cell extracts is Dicer. We find that Dicer is capable of discriminating highly functional versus poorly functional siRNAs by recognizing the presence of 2-nt 3' overhangs and the thermodynamic properties of 2-4 bp on both ends of effective siRNAs. Our results suggest a role for Dicer in pre-selection of effective siRNAs for handoff to Ago2. This initial selection is reflective of the overall silencing potential of an siRNA.
A scientometric analysis of knowledge management and intellectual capital academic literature (1994-2008)

Purpose – The purpose of this study is to conduct a scientometric analysis of the body of literature contained in 11 major knowledge management and intellectual capital (KM/IC) peer-reviewed journals. Design/methodology/approach – A total of 2,175 articles published in 11 major KM/IC peer-reviewed journals were carefully reviewed and subjected to scientometric data analysis techniques. Findings – A number of research questions pertaining to country, institutional and individual productivity, co-operation patterns, publication frequency, and favourite inquiry methods were proposed and answered. Based on the findings, many implications emerged that improve one’s understanding of the identity of KM/IC as a distinct scientific field. Research limitations/implications – The pool of KM/IC journals examined did not represent all available publication outlets, given that at least 20 peer-reviewed journals exist in the KM/IC field. There are also KM/IC papers published in other non-KM/IC specific journals. However, the 11 journals that were selected for the study have been evaluated by Bontis and Serenko as the top publications in the KM/IC area. Practical implications – Practitioners have played a significant role in developing the KM/IC field. However, their contributions have been decreasing. There is still very much a need for qualitative descriptions and case studies. It is critically important that practitioners consider collaborating with academics for richer research projects. Originality/value – This is the most comprehensive scientometric analysis of the KM/IC field ever conducted.
Employment Effects of Different Innovation Activities: Microeconometric Evidence

Using the model recently developed by Jaumandreu (2003) this paper reports new results on the relationship between innovation and employment growth in Germany. The model is tailor-made for analysing firm-level employment effects of innovations using specific information provided by CIS data. It establishes a theoretical link between employment growth and innovation output. The econometric analysis confirms that product innovations have a positive impact on employment. In contrast to previous studies, this effect is independent of the novelty degree. Moreover, different employment effects between manufacturing and service firms regarding process innovations were found. Finally, from a cross country perspective the results for Germany are similar to those found for Spain and the UK.
3 DCNN for Lung Nodule Detection And False Positive Reduction

The diagnosis of pulmonary nodules can be roughly divided into three steps: lung area extraction, lung nodule detection, false positive reduction. This article focuses on the nodule detection and false positive reduction. For nodule detection, we design a 3D nodule detector network motivated by the work of Feature Pyramid Networks and the 1st place team of Kaggle Data Science Bowl competition. For the large number of candidates detected by the detection model, we use two 3DCNN classifiers to determine which candidates are false-positive. A 3D network performs better than a 2D network as it also captures the vertical information of nodules. Also, focal loss [2] function is used to replace the cross-entropy loss function, which has been proved that it can deal with the problem of unbalanced classification. Furthermore, we use Batch Normalization [3] and weight initialization of convolution kernel by Xavier [4] and obtained good result.
Phyllodes tumors: race-related differences.

BACKGROUND
Phyllodes tumors (PT) are rare breast malignancies accounting for 0.5% to 1% of all breast tumors. PT have unpredictable behavior, with recurrence rates as high as 40%. A dearth of information exists about racial differences; elucidation of these differences is the objective of this study.


STUDY DESIGN
A retrospective review of patients treated for PT at either Moffitt Cancer Center or University of Texas Health Science Center San Antonio from 1999 to 2010.


RESULTS
Of the 124 patients, 71 (57%) were treated at Moffitt Cancer Center and 53 (42%) at University of Texas Health Science Center San Antonio. Mean age at diagnosis was 44 years (15 to 70 years). Thirty-three patients required mastectomy. Combining both cohorts, 42% of the patients were Caucasian, 43% were Hispanic, and 12% were black. Tumors were benign in 49% patients, borderline in 35%, and malignant in 16%, with a higher percentage of borderline and malignant tumors in Hispanic patients (p < 0.01). Hispanic patients tended to have larger tumors and higher mitotic rates (p = 0.01; p = 0.03). At a median follow-up time of 13 months, the local recurrence rate (6.4%) was associated with tumor size, tumor grade, mitotic rate, and close margin status (<2 mm) (p <0.01; p = 0.01; p = 0.01; p = 0.04). However, these findings did not translate into a survival difference by race.


CONCLUSIONS
In this multi-institutional review of PT we found substantial pathologic differences by race with higher-grade tumors present more often in Hispanic patients. These differences did not substantially affect outcomes at short-term follow-up. Further investigation into additional molecular, biologic factors, geographic impact, and socioeconomic factors is needed to more clearly delineate this finding.
Lifestyle counseling in hypertension-related visits – analysis of video-taped general practice visits

BACKGROUND
The general practitioner (GP) can play an important role in promoting a healthy lifestyle, which is especially relevant in people with an elevated risk of cardiovascular diseases due to hypertension. Therefore, the aim of this study was to determine the frequency and content of lifestyle counseling about weight loss, nutrition, physical activity, and smoking by GPs in hypertension-related visits. A distinction was made between the assessment of lifestyle (gathering information or measuring weight or waist circumference) and giving lifestyle advice (giving a specific advice to change the patient's behavior or referring the patient to other sources of information or other health professionals).


METHODS
For this study, we observed 212 video recordings of hypertension-related visits collected within the Second Dutch National Survey of General Practice in 2000/2001.


RESULTS
The mean duration of visits was 9.8 minutes (range 2.5 to 30 minutes). In 40% of the visits lifestyle was discussed (n = 84), but in 81% of these visits this discussion lasted shorter than a quarter of the visit. An assessment of lifestyle was made in 77 visits (36%), most commonly regarding body weight and nutrition. In most cases the patient initiated the discussion about nutrition and physical activity, whereas the assessment of weight and smoking status was mostly initiated by the GP. In 35 visits (17%) the GP gave lifestyle advice, but in only one fifth of these visits the patient's motivation or perceived barriers for changing behavior were assessed. Supporting factors were not discussed at all.


CONCLUSION
In 40% of the hypertension-related visits lifestyle topics were discussed. However, both the frequency and quality of lifestyle advice can be improved.
Long-term safety and efficacy of ramelteon in Japanese patients with chronic insomnia.

OBJECTIVE
To evaluate the safety of ramelteon, a highly selective MT₁/MT₂ melatonin receptor agonist, during 24 weeks' treatment of Japanese patients with chronic insomnia.


METHODS
In a single-blind, flexible-titration, multicenter study incorporating placebo run-in and run-out periods, 190 adults with chronic insomnia received ramelteon 4 or 8 mg, titrated up to 16 mg if necessary, for 24 weeks. Primary endpoints included adverse events, residual effects, rebound insomnia, withdrawal symptoms, and dependence. Secondary endpoints included subjective sleep latency and total sleep time.


RESULTS
Drug-related adverse events occurred in 11.6% of patients. No clinically important changes occurred in biochemical, hematological or endocrine parameters. There were no signs of next-day residual effect, rebound insomnia, withdrawal symptoms or dependence. Mean subjective sleep latency decreased significantly, and total sleep time increased significantly; both reached a plateau by week 20 and were sustained thereafter (P<0.0001).


CONCLUSIONS
Ramelteon was well tolerated in adult Japanese patients with chronic insomnia and did not cause deterioration of efficacy, residual effects, rebound insomnia, withdrawal symptoms, or dependence after 24 weeks' treatment.
Luminescence of Eu-doped langanite nanopowders synthesized by a citrate sol–gel method

Abstract Eu-doped langanite nanopowders were prepared by a citrate sol–gel method and annealed in air at various temperatures between 700 °C and 1000 °C. For annealing temperatures up to 800 °C, only the langanite phase is observed. For higher annealing temperatures, part of the langanite powder transforms in perovskite (LaGaO 3 ), as evidenced in both XRD and luminescence spectra. Regardless the annealing temperature, the lifetime of 5 D 0 remains close to 1 ms. The reddish color of the powders due to color centers associated to oxygen defects intensifies with increasing annealing temperature. The best efficiency of the Eu-langanite nanopowders was obtained for the sample annealed at 700 °C (∼60% of the efficiency of the bulk material).
Fitting Smooth Surfaces to Dense Polygon Meshes

Recent progress in acquiring shape from range data permits the acquisition of seamless million-polygon meshes from physical models. In this paper, we present an algorithm and system for converting dense irregular polygon meshes of arbitrary topology into tensor product B-spline surface patches with accompanying displacement maps. This choice of representation yields a coarse but efficient model suitable for animation and a fine but more expensive model suitable for rendering. The first step in our process consists of interactively painting patch boundaries over a rendering of the mesh. In many applications, interactive placement of patch boundaries is considered part of the creative process and is not amenable to automation. The next step is gridded resampling of each boundedsection of the mesh. Our resampling algorithm lays a grid of springs across the polygon mesh, then iterates between relaxing this grid and subdividing it. This grid provides a parameterization for the mesh section, which is initially unparameterized. Finally, we fit a tensor product B-spline surface to the grid. We also output a displacement map for each mesh section, which represents the error between our fitted surface and the spring grid. These displacement maps are images; hence this representation facilitates the use of image processing operators for manipulating the geometric detail of an object. They are also compatible with modern photo-realistic rendering systems. Our resampling and fitting steps are fast enough to surface a million polygon mesh in under 10 minutes important for an interactive system.

A Sharp Nonlinear Gagliardo-Nirenberg-Type Estimate and Applications to the Regularity of Elliptic Systems

The seminal paper of Coifman et al. (1993) has triggered numerous new applications of Hardy spaces and the space BMO of functions of bounded mean oscillation to nonlinear partial differential equations. These applications include various problems of variational and geometric origin: harmonic and p-harmonic maps, H-systems, wave maps; (see, e.g., Bethuel, 1993; Evans, 1991; Hélein, 1998, 2002; Toro and Wang, 1995) and many others. In a vague sense, a common feature of all those works is that the duality of BMO and the Hardy space 1 are much more subtle than the duality of L and L1. In many instances, the local BMO norm of a function
A KNOWLEDGE REPOSITORY FOR BEHAVIORAL MODELS IN ENGINEERING DESIGN

Computer simulations and behavioral modeling are becoming increasingly important in product development processes. Simulations can result in better decisions in less time by providing the designers with greater understanding of the products behavior. However, behavior model creators (i.e. analysts) and behavior model users (i.e. designers) often do not have the same level of understanding of the model, thus limiting the reuse of a model. Our goal in this research is to develop a clean interface that reduces the knowledge gap between engineering design and analysis by facilitating reuse of behavioral models. To achieve a higher level of reuse in the product design process, we propose a meta-data representation for formally characterizing behavioral models. The meta-data representation captures the assumptions, limitations, accuracy, and context of engineering behavioral models. Based on this knowledge representation, a proof-of-concept repository is implemented for archiving and exchanging reusable behavioral models. The knowledge representation and implementation is illustrated with a simple cantilever beam example.
Characteristics of Suicide Attempts in Anorexia and Bulimia Nervosa: A Case–Control Study

OBJECTIVE
Compared to other eating disorders, anorexia nervosa (AN) has the highest rates of completed suicide whereas suicide attempt rates are similar or lower than in bulimia nervosa (BN). Attempted suicide is a key predictor of suicide, thus this mismatch is intriguing. We sought to explore whether the clinical characteristics of suicidal acts differ between suicide attempters with AN, BN or without an eating disorders (ED).


METHOD
Case-control study in a cohort of suicide attempters (n = 1563). Forty-four patients with AN and 71 with BN were compared with 235 non-ED attempters matched for sex, age and education, using interview measures of suicidal intent and severity.


RESULTS
AN patients were more likely to have made a serious attempt (OR = 3.4, 95% CI 1.4-7.9), with a higher expectation of dying (OR = 3.7,95% CI 1.1-13.5), and an increased risk of severity (OR = 3.4,95% CI 1.2-9.6). BN patients did not differ from the control group. Clinical markers of the severity of ED were associated with the seriousness of the attempt.


CONCLUSION
There are distinct features of suicide attempts in AN. This may explain the higher suicide rates in AN. Higher completed suicide rates in AN may be partially explained by AN patients' higher desire to die and their more severe and lethal attempts.
Maintenance treatment of schizophrenia with risperidone or haloperidol: 2-year outcomes.

OBJECTIVE
Most controlled studies comparing second-generation and conventional antipsychotics have focused on the acute treatment of schizophrenia. The authors compared symptom outcomes, side effects, and social adjustment in stable schizophrenia outpatients who received 2 years of maintenance treatment with risperidone or haloperidol.


METHOD
This was a 2-year, randomized, double-blind comparison of 6 mg of risperidone versus haloperidol in 63 patients with stabilized DSM-IV schizophrenia. Study patients also received 15 months of standard behavioral skills training or enhanced training with a case manager who promoted patients' use of their skills in the community.


RESULTS
The risk of psychotic exacerbations and the risk of leaving the study were similar for both drug treatment groups. However, patients who received both risperidone and the enhanced community-based skills training were more likely to remain in the study than those in the other treatment groups. Patients demonstrated significant improvement in score on the Brief Psychiatric Rating Scale over time with both medications. There were no between-group differences in cluster scores for thought disturbance, hostile-suspiciousness, and withdrawal-retardation. A significant between-group difference favoring risperidone was found for the anxious-depression cluster. Risperidone resulted in significantly greater reductions in tremor and akathisia and greater improvements in most items on the SCL-90-R.


CONCLUSIONS
When compared with patients given a low dose of haloperidol, risperidone-treated patients experienced similar improvements in positive and negative symptoms and similar risks of psychotic exacerbations. However, risperidone-treated patients appeared to feel subjectively better, as indicated by less anxiety and depression and fewer extrapyramidal side effects.
Security injections: modules to help students remember, understand, and apply secure coding techniques

With our global reliance on software, secure and robust programming has never been more important. Yet academic institutions have been slow to add secure coding to the curriculum. We present a model using checklist-based security injection modules to increase student awareness and ability to apply secure coding principles, specifically - identify, understand, and correct key security issues in code. The model is evaluated by mapping assessment questions to the cognitive dimension of the revised Bloom's taxonomy. Experiments with students in four sections of CS0 and CS1 show that students using our modules perform significantly better at remembering, understanding and applying secure coding concepts. Students exposed to the modules also show increased ability to write code to address specific security issues.
Titration of Insulin Glargine in Patients with Type 2 Diabetes Mellitus in Asia: Physician- Versus Patient-Led? Rationale of the Asian Treat to Target Lantus Study (ATLAS).

OBJECTIVE
the AT-LANTUS Study demonstrated that a simple subject-administered titration algorithm significantly improved glycemic control with a low incidence of severe hypoglycemia compared with a physician-managed titration. However, in the AT-LANTUS Study Asian patients were under-represented, and more than 70% of the patients were already treated with insulin. The Asian Treat to Target Lantus Study (ATLAS) will compare the effectiveness of a patient- versus physician-led initiation of insulin glargine-based basal management in the specific setting of Asia and Russia (as is routinely used in Western countries). This report presents the study design of ATLAS.


METHODS
subjects are 40-75 years old (body mass index ≥ 20 and ≤ 40 kg/m(2)) with type 2 diabetes mellitus (T2DM) of >2 years in duration, suboptimally controlled (hemoglobin A1c [HbA1c] ≥ 7.0% and ≤ 11%) with stable doses of two oral antidiabetes drugs (OADs) (sulfonylureas, biguanides, α-glucosidase inhibitors, dipeptidyl peptidase-IV inhibitors, and glinides) for more than 3 months, and not using insulin. The subjects will be randomized to either the patient-led or the physician-led titration arm, where the insulin dose will be adjusted to achieve a target fasting plasma glucose (FPG) value of 110 mg/dL (6.1 mmol/L).


STUDY OUTCOMES
the primary outcome will be change in mean HbA1c at 6 months from baseline. The analysis plan prespecifies a hierarchical testing procedure for the primary outcome. If noninferiority is achieved using a 0.3% HbA1c boundary, we will go on to undertake a test for superiority. Secondary outcomes will also include number of patients reaching American Diabetes Association target HbA1c with or without hypoglycemia and analysis of FPG profiles in the two groups.


CONCLUSIONS
ATLAS will provide information on the relative safety and efficacy of a patient- versus physician-led titration strategy for insulin glargine-based basal insulin initiation in patients who are not controlled with two OADs in Asia and Russia. The results of the study may guide policymakers to translate data into clinical practice.
Conventional Orthography for Dialectal Arabic

Dialectal Arabic (DA) refers to the day-to-day vernaculars spoken in the Arab world. DA lives side-by-side with the official language, Modern Standard Arabic (MSA). DA differs from MSA on all levels of linguistic representation, from phonology and morphology to lexicon and syntax. Unlike MSA, DA has no standard orthography since there are no Arabic dialect academies, nor is there a large edited body of dialectal literature that follows the same spelling standard. In this paper, we present CODA, a conventional orthography for dialectal Arabic; it is designed primarily for the purpose of developing computational models of Arabic dialects. We explain the design principles of CODA and provide a detailed description of its guidelines as applied to Egyptian Arabic.
