Use of body knowledge and cloud computing tools to develop software projects based in innovation

A Body of Knowledge (BOK) is a term used to represent the complete set of concepts, terms, and activities that make up a professional domain. It encompasses the core teaching skills and research in a field or industry [13]. One of the main concerns of the software industry is to develop the talent of its human resources since the quality and innovation of its products and services depend of a great extent on the Knowledge, the ability, and the talent of technical engineers. In the educational area the used of BOK and Cloud Computing Tools are becoming the best way to provide solutions that meet the current need for greater collaboration between business, industry, education, and society; for this reason, the development of software products based in innovation is important for the professional life of a software engineering, since it leads to transform routine tasks into automated tasks; in the same way, it allows to manage processes focused on aligning services of Information Technology (IT) to the needs of companies with an emphasis on the benefits that the final customer added may perceive to the factor of I+D+I in order to create an innovative product. The current study focuses on the use of computer tools in the cloud in its phases: definition, planning, and control of software project based on the innovation as a tool for development and knowledge generation based in BOK. The tools of Computing in the Cloud analyzed were: Alfresco, Redbooth, DotProject, Dealines, and Redmine. The use of these tools permitted to obtain information to formulate a BOK in the context of projects.

Empirical likelihood based hypothesis testing

Omnibus tests for various nonparametric hypotheses are developed using the empirical likelihood method. These include tests for symmetry about zero, changes in distribution, independence and exponentiality. The approach is to localize the empirical likelihood using a suitable "time" variable implicit in the null hypothesis and then form an integral of the log-likelihood ratio statistic. The asymptotic null distributions of these statistics are established. In simulation studies, the proposed statistics are found to have greater power than corresponding Cramer-von Mises type statistics.
Characteristics and Recovery Performance of VSC-HVDC DC Transmission Line Fault

As a new approach of DC transmission scheme, Voltage Sourced Converter based HVDC (VSC-HVDC) transmits electric energy by connecting rectifier and inverter through DC transmission line, which is the same as LCC-HVDC. However, the fault performance and relevant restart demand are different due to that VSC-HVDC is based on voltage sourced converter. This paper analyzes the mechanism of DC line-to-ground fault and line-to-line fault in VSC-HVDC scheme, and then proposes the recovery demand of temporary faults at overhead line scheme. By establishing an electromagnetic transient model under PSCAD/EMTDC, the performance under DC transmission line transients has been thoroughly investigated. According to the characteristics under simulation, the solutions of key points during recovery process are proposed, which include the grounding design, adopting monopolar topology and modifying the transformer type etc. Keywords-VSC-HVDC; DC transmission line; grounding design; fault recovery; bipolar transmission system; monopolar transmission system
Your morals might be your moods

We test the effect of mood on behavior in a gift-exchange game. To induce a ‘bad mood’, second movers watched a sad movie before playing the game; to induce a ‘good mood’, they watched a funny movie. Mood induction was effective: subjects who saw the funny movie reported a significantly better mood than those who saw the sad movie. These two moods lead to significant differences in behavior. We find that a bad mood implies more reciprocity while a good mood implies more generosity. Furthermore, first movers make more money when second movers are in a bad mood. © 2005 Elsevier B.V.

A comprehensive framework for modeling set-based business rules during conceptual database design

Business rules are the basis of any organization. From an information systems perspective, these business rules function as constraints on a database helping ensure that the structure and content of the real world—sometimes referred to as miniworld—is accurately incorporated into the database. It is important to elicit these rules during the analysis and design stage, since the captured rules are the basis for subsequent development of a business constraints repository. We present a taxonomy for set-based business rules, and describe an overarching framework for modeling rules that constrain the cardinality of sets. The proposed framework results in various types constraints, i.e., attribute, class, participation, projection, co-occurrence, appearance and overlapping, on a semantic model that supports abstractions like classification, generalization/specialization, aggregation and association. We formally define the syntax of our proposed framework in Backus-Naur Form and explicate the semantics using first-order logic. We describe partial ordering in the constraints and define the concept of metaconstraints, which can be used for automatic constraint consistency checking during the design stage itself. We demonstrate the practicality of our approach with a case study and show how our approach to modeling business rules seamlessly integrates into existing database design methodology. Via our proposed framework, we show how explicitly capturing data semantics will help bridge the semantic gap between the real world and its representation in an information system. r 2003 Elsevier Ltd.

La Classification non Supervisée (Clustering) de Documents Textuels par les Automates Cellulaires

Résumé : Dans cet article nous présentons un automate cellulaire (Class_AC) pour résoudre un problème de text mining en l’occurrence la classification non supervisée (Clustering). Avant de procéder à l’expérimentation par l’automate cellulaire, nous avons vectorisés nos données en procédant à l’indexation des documents textuels provenant de la base de donnée REUTERS 21578 par l’approche Wordnet. L’automate que nous proposons dans cet article est une grille de cellules de structure plane avec un voisinage découlant de cette structure (planaire). Trois fonctions de transitions ont servi à faire varier l’automate ayant quatre états pour chaque cellule. Les résultats obtenus montrent que la machine virtuelle à calcul parallèle (Class_AC) regroupe efficacement des documents similaires à un seuil prés.
Servo performance of a BLDC drive with instantaneous torque control

Brushless DC (BLDC) drives with permanent-magnet motors are suitable as servo-motors if properly controlled. Their performance can be superior to that of conventional DC servos if NdFeB or rare-earth cobalt magnets are used for motor excitation and novel control techniques are implemented for its servo performance. The availability of inexpensive but high-performance digital signal processors allows the implementation of a novel instantaneous torque control algorithm for the BLDC drive applications. Described are the servo performances of a BLDC drive with instantaneous torque control. To assess the quality of this controller, its performance is compared with those obtained using conventional current controllers. Details of the control strategies are also described.<<ETX>>
American physicians and dual loyalty obligations in the "war on terror"

BACKGROUND
Post-September 11, 2001, the U.S. government has labeled thousands of Afghan war detainees "unlawful combatants". This label effectively deprives these detainees of the protection they would receive as "prisoners of war" under international humanitarian law. Reports have emerged that indicate that thousands of detainees being held in secret military facilities outside the United States are being subjected to questionable "stress and duress" interrogation tactics by U.S. authorities. If true, American military physicians could be inadvertently becoming complicit in detainee abuse. Moreover, the American government's openly negative views towards such detainees could result in military physicians not wanting to provide reasonable care to detainees, despite it being their ethical duty to do so.


DISCUSSION
This paper assesses the physician's obligations to treat war detainees in the light of relevant instruments of international humanitarian law and medical ethics. It briefly outlines how detainee abuse flourished in apartheid South Africa when state physicians became morally detached from the interests of their detainee patients. I caution U.S physicians not to let the same mindset befall them. I urge the U.S. medical community to advocate for detainee rights in the U.S, regardless of the political culture the detainee emerged from. I offer recommendations to U.S physicians facing dual loyalty conflicts of interest in the "war on terror".


SUMMARY
If U.S. physicians are faced with a conflict of interest between following national policies or international principles of humanitarian law and medical ethics, they should opt to adhere to the latter when treating war detainees. It is important for the U.S. medical community to speak out against possible detainee abuse by the U.S. government.

A social networked learning adoption model for higher education institutions in developing countries

Purpose – The purpose of this paper is to establish a model for adopting social networked learning in higher institutions of learning in developing countries of Africa. Design/methodology/approach – Mixed methods research methodology involving survey and interviews was adopted in the collection of data for building the model. The model was theoretically underpinned by the Technology Acceptance Model and the social constructivist learning theory, and was built and validated using structural equation modelling and Delphi techniques respectively. Findings – Adoption of social networked learning in developing countries of Africa requires self efficacy, reliable technical and administrative support, infrastructure, system interactivity, adequate budgeting and accountability, and a flexible organisational culture. Practical implications – The model provides a framework for integrating social software tools with the traditional learning systems of developing countries of Africa. This has a positive outcome of providing social constructivist information and communication technology (ICT) supported learning at low or no cost. Social implications – The model has the potential to encourage formation of communities of practice to encourage development of social learning and a student-centered pedagogy. Originality/value – The novelty of this research lies in the extension of the traditional technology acceptance models with constructs for proper budgeting and accountability and organisational culture. Time and other resources need to be devoted to developing social networked learning and the model takes this into account.

Towards a Forensic-Based Service Oriented Architecture Framework for Auditing of Cloud Logs

Cloud computing log digital investigations relate to the investigation of a potential crime using the digital forensic evidence from a virtual machine (VM) host operating system using the hypervisor event logs. In cloud digital log forensics, work on the forensic reconstruction of evidence on VM hosts system is required, but with the heterogeneous complexity involved with an enterprise's private cloud not to mention public cloud distributed environments, a possible Web Services-centric approach may be required for such log supported investigations. A data cloud log forensics service oriented architecture (SOA) audit framework for this type of forensic examination needs to allow for the reconstruction of transactions spanning multiple VM hosts, platforms and applications. This paper explores the requirements of a cloud log forensics SOA framework for performing effective digital investigation examinations in these abstract web services environments. This framework will be necessary in order to develop investigative and forensic auditing tools and techniques for use in cloud based log-centric SOAs.
Adjuvant chemotherapy is associated with improved overall survival in pelvic node-positive penile cancer after lymph node dissection: a multi-institutional study.

OBJECTIVES
We determined whether adjuvant chemotherapy (AC) would be associated with improved survival after lymph node dissection (LND) for patients with penile cancer (PeCa) who have positive pelvic lymph nodes (PPLNs).


METHODS
We retrospectively identified patients across 4 centers with penile squamous cell carcinoma who underwent LND from 1978 to 2013 and were found to have PPLNs. Patients who received chemotherapy before surgery or in the presence of recurrent disease were excluded. Cox regression was used to evaluate the association of AC with overall survival (OS), which was estimated using the Kaplan-Meier method. Differences in OS were determined with the log-rank test.


RESULTS
During the study period, 141 patients who underwent LND for PeCa had PPLNs, and 84 of them met inclusion criteria. Median number of PPLNs was 2 (interquartile range [IQR]: 4-7), with 10% of cases occurring bilaterally and 55% having pelvic extranodal extension. AC was used in 36 (43%) patients. Patients who received AC were younger (P = 0.014), had less-aggressive penile tumor pathology (P<0.01), were less likely to receive adjuvant radiation (P<0.01), had less bilateral inguinal disease (P = 0.019), and had more inguinal extranodal extension (P = 0.042). Median follow-up was 12.1 months. Estimated median OS was 21.7 months (IQR: 11.8-104) in patients who received AC vs. 10.1 (IQR: 5.6-48.1) in those who did not (P = 0.048). AC was independently associated with improved OS on multivariate analysis (hazard ratio: 0.40; 95% CI: 0.19-0.87; P = 0.021).


CONCLUSIONS
AC is associated with improved OS in patients with PeCa who have PPLNs after LND. Prospective studies are needed to demonstrate causality.

ALVEOLAR BONE HEIGHT IN PATIENTS WITH MILD HYPODONTIA

The purpose of the present study is to investigate whether there are significant differences in the alveolar bone height of a group of individuals with mild hypodontia when compared to a matched in age and gender control group of unaffected individuals. A retrospective cross-sectional analytical study of panoramic radiographs (OPTs) of patients with mild hypodontia who attended Aberdeen Dental Hospital, UK, aged 11 to 18 years, and of radiographs of patients of a matched in age and gender control group. Twenty two alveolar bone height measurements were recorded on OPT radiographs of 65 mild hypodontia and 65 ageand gender-matched control individuals with the aid of a digital calliper as described in previous studies. These variables were compared between the two groups using an Independent samples t-test. No statistically significant differences were found between a group of patients with mild hypodontia and a matched in age and gender control group (p>0.05) for any of the alveolar bone height measurements. The results of this study support the use of dental implants in the multidisciplinary management of patients with mild hypodontia for the restoration of their congenitally missing teeth.

National Prostate Cancer Screening Rates After the 2012 US Preventive Services Task Force Recommendation Discouraging Prostate-Specific Antigen-Based Screening.

PURPOSE
In 2012, the US Preventive Services Task Force (USPSTF) discouraged prostate-specific antigen (PSA) -based prostate cancer screening. Previous USPSTF recommendations did not appreciably alter prostate cancer screening. Therefore, we designed a trend analysis to determine the population-based impact of the 2012 recommendation.


METHODS
The nationally representative National Health Interview Survey was used to estimate the proportion of men age 40 years and older who saw a physician and were screened for prostate cancer in 2013. An externally validated 9-year mortality index was used to analyze screening rates based on remaining life expectancy. Screening rates from 2005, 2010, and 2013 were compared using logistic regression.


RESULTS
PSA-based screening did not significantly change from 2010 to 2013 among 40- to 49-year-old men (from 12.5% to 11.2%; P = .4). Screening rates significantly declined in men age 50 to 59 years (from 33.2% to 24.8%; P < .01), age 60 to 74 years (from 51.2% to 43.6%; P < .01), and age 75 years or older (from 43.9% to 37.1%; P = .03). A large percentage of men were screened for prostate cancer despite a high risk (> 52%) of 9-year mortality, including approximately one third of men older than age 75 years. Approximately 1.4 million men age 65 years or older with a high risk (> 52%) of 9-year mortality were screened in 2013.


CONCLUSION
Prostate cancer screening significantly declined among men older than age 50 years after the 2012 USPSTF guideline discouraging PSA-based screening. A significant proportion of men continue to be screened despite a high risk of 9-year mortality, including one third of men age 75 years and older.
Paclitaxel plus bevacizumab versus paclitaxel alone for metastatic breast cancer.

BACKGROUND
In an open-label, randomized, phase 3 trial, we compared the efficacy and safety of paclitaxel with that of paclitaxel plus bevacizumab, a monoclonal antibody against vascular endothelial growth factor, as initial treatment for metastatic breast cancer.


METHODS
We randomly assigned patients to receive 90 mg of paclitaxel per square meter of body-surface area on days 1, 8, and 15 every 4 weeks, either alone or with 10 mg of bevacizumab per kilogram of body weight on days 1 and 15. The primary end point was progression-free survival; overall survival was a secondary end point.


RESULTS
From December 2001 through May 2004, a total of 722 patients were enrolled. Paclitaxel plus bevacizumab significantly prolonged progression-free survival as compared with paclitaxel alone (median, 11.8 vs. 5.9 months; hazard ratio for progression, 0.60; P<0.001) and increased the objective response rate (36.9% vs. 21.2%, P<0.001). The overall survival rate, however, was similar in the two groups (median, 26.7 vs. 25.2 months; hazard ratio, 0.88; P=0.16). Grade 3 or 4 hypertension (14.8% vs. 0.0%, P<0.001), proteinuria (3.6% vs. 0.0%, P<0.001), headache (2.2% vs. 0.0%, P=0.008), and cerebrovascular ischemia (1.9% vs. 0.0%, P=0.02) were more frequent in patients receiving paclitaxel plus bevacizumab. Infection was more common in patients receiving paclitaxel plus bevacizumab (9.3% vs. 2.9%, P<0.001), but febrile neutropenia was uncommon (<1% overall).


CONCLUSIONS
Initial therapy of metastatic breast cancer with paclitaxel plus bevacizumab prolongs progression-free survival, but not overall survival, as compared with paclitaxel alone. (ClinicalTrials.gov number, NCT00028990 [ClinicalTrials.gov].).
What is eating you? Stress and the drive to eat

Non-human animal studies demonstrate relationships between stress and selective intake of palatable food. In humans, exposure to laboratory stressors and self-reported stress are associated with greater food intake. Large studies have yet to examine chronic stress exposure and eating behavior. The current study assessed the relationship between stress (perceived and chronic), drive to eat, and reported food frequency intake (nutritious food vs. palatable non-nutritious food) in women ranging from normal weight to obese (N=457). Greater reported stress, both exposure and perception, was associated with indices of greater drive to eat-including feelings of disinhibited eating, binge eating, hunger, and more ineffective attempts to control eating (rigid restraint; r's from .11 to .36, p's<.05). These data suggest that stress exposure may lead to a stronger drive to eat and may be one factor promoting excessive weight gain. Relationships between stress and eating behavior are of importance to public health given the concurrent increase in reported stress and obesity rates.
