Rating Prediction for Software Developers by Integrating OSS Community and Crowd Sourcing

Success of software developping project depend on skills of developers in the teams, however, predicting such skills is not a obvious problem. In crowd sourcing services, such level of the skills is rated by the users. This paper aims to predict the rating by integrating open source software (OSS) communities and crowd soursing services. We show that the problem is reduced into the feature construction problem from OSS communities and proposes the s-index, which abstract the level of skills of the developers based on the developed projects. Specifically, we inetgrate oDesk (a crowd sourcing service) and GitHub (an OSS community), and construct prediction model by using the ratings from oDesk as a training data. The experimental result shows that our method outperforms the models without s-index for the aspect of nDCG.
A survey of individual social capital and mental wellbeing of older persons, living in a residential facility in Durban, KwaZulu-Natal and the readiness of the setting for technology driven mental health promotion.

Aim The aim of the study was to describe the individual social capital and mental wellbeing of older persons (60+) living in a residential facility in Durban, KwaZuluNatal, and the readiness of staff and residents for the projected introduction of technologically assisted communication (TAC). The findings of the study were intended to facilitate planning for and implementation of, future interventions using technologically assisted communication for the purpose of improving individual social capital and mental wellbeing. Methods The research design was a non-experimental quantitative two part descriptive survey using self-administered questionnaires for residents (75) and direct care staff (35). There was purposive sampling for the residential facility and convenient sampling of the respondents (residents and direct care staff) who met the inclusion criteria. Merging the Canadian Policy Research Initiative framework and the Technology Acceptance Model provided the structure for the study. The residents’ questionnaire consisted of questions from the Australian Bureau of Statistics Indigenous Questionnaire, four well validated scales and the same questions to assess technological readiness in the staff and residents. Data was entered into SPSS v 21 and analysed using measures for central tendency, nonparametric tests as well as a logistic regression. Results The 75 respondents were representative of the residential facility’s population in all the demographic characteristics, but not generalizable to the South African older person population. The WHO-5 cut off score of 13, showed that the majority had a good sense of mental wellbeing, while measuring with any negative category showed residents’ having a moderate sense of mental wellbeing. There was consistency between the Kessler-6 and the WHO-5. The levels of Loneliness were high. Social connectedness with outside activities was a strong predictor of
Immunobiology of IFRD1, a novel genetic modifier of cystic fibrosis lung disease.

Cystic fibrosis is the most common, lethal autosomal recessive disorder in the United States. Lung disease is the major cause of morbidity and mortality in CF. In the CF lung, chronic infection and dysregulated neutrophilic inflammation lead to progressive airway destruction. Despite the molecular insights afforded by identification of disease-causing gene, CFTR, a clear understanding of the pathogenesis of lung disease in CF remains elusive. There is a poor correlation of genotype with phenotype in lung disease in CF, which strongly suggests that the expression of lung disease in CF is influenced by environmental exposures and/or modifier genes. To search for genes modifying CF lung disease, the Karp lab performed a genome-wide association study in collaboration with GMSG cohort, validating top candidates in collaboration with the CFTSS cohort. Using this approach, genetic variation in IFRD1 was identified and verified as a modifier of lung disease severity in CF. IFRD1 is a HDAC-dependent transcriptional co-activator or co-repressor whose expression is particularly enriched in neutrophils.The goal of my dissertation studies was mechanistic insight into the modulation of CF lung disease by IFRD1. This dissertation research provides evidence in favor of the hypothesis that IFRD1 modulates the course of airway disease in CF through regulation of neutrophil effector function. This study also strongly suggests a mechanism by which IFRD1 modulates neutrophil function in a HDAC-dependent manner to co-suppress the expression of ATF3, a transcriptional repressor of NF-B activity in neutrophils. Finally, this research emphasizes the translational implications for therapeutic targeting of ii neutrophils in CF. This study suggests that the IFRD1/HDAC axis may provide a tractable therapeutic target in CF, and the plethora of other diseases in which neutrophils play an important pathogenic role.

Multiple Sequence Alignment based on Developed Genetic Algorithm

Background: Multiple Sequences Alignment (MSA) is the one of the most important research themes in bioinformatics as well known that the Genetic Algorithm (GA) working on finding the optimal solution, but it may take long generations to get to the solution and this is a problem especially in protein. Methods: In this research the dataset has been used in the form of Deoxyribonucleic acid (DNA) sequences, and protein sequences for the purpose of global alignment all these sequences belong to a human. Aligning several sequences cannot be done in polynomial time and therefore, heuristic methods such as GA can be used to found approximate solutions of MSA problems. Several algorithms based on genetic algorithms have been developed for this problem in recent years. In this paper, a new evaluation process, good mutation probability, new recombination operators, and a strong condition for termination have been used by developed genetic algorithm. Findings: The strength of the proposed GA is excellent matching and a good time with less storage. The experimental results show that the proposed algorithm is capable of finding good Multiple Sequence Alignment in contrast to a traditional genetic algorithm while it uses low computational complexity. The weaknesses of the traditional GA have been solved by the developed GA. Applications: Multiple sequence alignment by using genetic algorithm plays a vital role in our day-to-day life for various biological purpose especially in a clinical laboratory.
Requirement Pattern Extraction using Cluster Based Framework - RAPID

Background/Objectives: In Software Engineering discipline, requirement phase plays vital role in success of a project. To make the requirement analysis process more effective, developers adopt several methods like goal-oriented, aspect-oriented, pattern-oriented etc. In the current scenario recurring requirements can be addressed effectively with requirement patterns rather applying a common procedure to all projects. Methods/Statistical analysis: While adopting common procedure to all project results in increasing cost of quality or even project failure due to the fact that every project is not having similar characteristics. To perform requirement process effectively, it is necessary to select a suitable requirement pattern for a project. Selecting relevant, applicable and reliable pattern is challengeable and prior knowledge is required. Findings: The proposed framework groups project characteristics and the pattern sets into k-clusters based on the clustering algorithm. The best suitable pattern will be filtered from the available pattern clusters by applying the filtering algorithm. The suggested patterns along with the situational constraints for a given situation will be stored in the data store. The stack holder can add new pattern details or can update the details of existing patterns. Applications/Improvements: Finds the analysis patterns that matches with the given situational characteristics and requirement of a project. Clustering enhanced with fuzzy to bring the improvement.
Exposure of Screen Time in Relationship with Obesity in Junior High School Adolescence in Yogyakarta

Obesity has been increasing throughout the world that also will impact to the increasing of non communicable disase realated to obesity. Obesity which is occurred since adolescence can worsen the problem because it will carry over until adult so it was necessary to prevent obesity by controlling the obesity risk factor. Some studies reveal that increasing obesity was emerged because of high screen time. Too much screen time can increase exposure of unhealthy snack and increase sedentary activity that was obesity risk factor. Objectives; to determine the relationship of screen time and obesity in adolescent in Junior High School in Yogyakarta. Material and Method; the type of research used was observational with a case control study approach. This research was conducted in 4 junior high schools in the city of Yogyakarta. The sample of this study was 120 students aged 12-15 years consisting of 60 students in the case group and 60 students in the control group selected by the proportionate random sampling method which then matched age and sex. Results; in this study it was found that there was a significant relationship between screen time of more than 2 hours/day and the risk of obesity in adolescent junior high school in Yogyakarta City (p=0.019) with an Odds Ratio of 2.6 (1.160-5.750). Higher screen time is significantly associated with a higher level of energy intake (p=0.037) with a Prevalence Ratio of 1.3 (1.025-1.638). Conclusion; it was found that there was a relationship between screen time and obesity in adolescent junior high school in Yogyakarta City.

Parallelization of the Alternating-Least-Squares Algorithm With Weighted Regularization for Efficient GPU Execution in Recommender Systems

Collaborative filtering recommender systems have become essential to many Internet services, providing, for instance, book recommendations at Amazon’s online e-commerce service, music recommendation in Spotify and movie recommendation in Netflix. Matrix factorization and Restricted Boltzmann Machines (RBMs) are two popular methods for implementing recommender systems, both providing superior accuracy over common neighborhood models. Both methods also shift much of the computation from the prediction phase to the model training phase, which enables fast predictions once the model has been trained. This thesis suggests a novel approach for performing matrix factorization using the Alternating-Least-Squares with Weighted-λ-Regularization (ALS-WR) algorithm on cuda (ALS-CUDA). The algorithm is implemented and evaluated in the context of recommender systems by comparing it to other commonly used approaches. These include an rbm and a stochastic gradient descent (SGD) approach. Our evaluation shows that significant speedups can be achieved by using cuda and gpus for training recommender systems. The als-cuda algorithm implemented in this thesis provided speedup factors of up to 175.4 over the sequential cpu als implementation and scales linearly with the number of cuda threads assigned to it until the gpus shared memory has been saturated. Comparing the performance of the als-cuda algorithm to cuda implementations of the sgd and the rbm algorithms shows that the als-cuda algorithm outperformed the rbm. For a sparse dataset, results indicate that the als-cuda algorithm performs slightly worse than the sgd implementation, while for a dense dataset, als-cuda outperforms the sgd. However, generally the advantage of the als-cuda algorithm does not necessarily lie in its speed, but also in the fact that it requires fewer parameters than the sgd. It therefore represents a viable option when some speed can be traded off for algorithmic stability, or when the dataset is dense.

Domenico Dragonetti in England (1794-1846): The Career of a Double Bass Virtuoso

Dragonetti devoted his life to the double bass. His career in England (1794-1846) is one of the most remarkable success stories in the annals of musical history. His unprecedented virtuosity elevated the double bass to a new status. In combination with his charismatic personality his musical talent dominated the English cultural world for more than fifty years. As performer, composer, collector, and friend, he exposed the unforeseen potential of the double bass. His formidable talent as a musician and businessman provides an unusual insight into nineteenth-century entrepreneurship. This first substantial biography and assessment of Dragonetti's career allows us to understand his importance in the history of music in general and of double-bass performance in particular.
Pre‐Columbian Tuberculosis in Northwest Argentina: Skeletal Evidence from Rincón Chico 21 Cemetery

Systematic excavation of collective burial sites makes possible the recovery of skeletal series which may show bony evidence of infectious pathological conditions. This paper presents the first evidence of the existence of tuberculosis in prehistoric populations of NW Argentina with a subsistence economy based on agriculture and pastoralism. The study was carried out on individuals from Rincon Chico 21 cemetery, a burial site located in the Santa Maria Valley, Catamarca, used between the Late Ceramic Period and the onset of the Inca empire expansion (AD 1000–1400). Six individuals out of the 70 so far excavated showed destructive lesions in the vertebral bodies and periosteal reactions in other bones. The morphology and distribution of bone lesions led us to rule out several diseases from a broad spectrum of possible diseases that could have affected the skeletal system. Thus, the lesions were interpreted as caused by mycobacterial infections (Mycobacterium tuberculosis Complex). Considering previous studies on the dynamics of biocultural interactions which take into account information related from contextual associations and chronology, we can conclude that a tuberculosis-like disease was present in prehistoric populations from NW Argentina.

Campus Responses to Dating Violence and Sexual Assault: Information from University Representatives

ABSTRACT Universities have an obligation to provide student victims with services that are easily accessible. This study focused on the provision of sexual assault and dating violence services of large, public 4-year institutions, as reported by university representatives. The sample included security officers from 45 universities who completed phone interviews between February and May 2013. Phone interviews consisted of 15 open-ended questions. The findings point to highly variable practices and services offered across campuses. The services most frequently reported by university representatives include counseling and police services. The findings also suggest that public 4-year institutions not only offer varied levels of services, but such services might not be readily available to student victims. Although many representatives identified underserved groups and suggestions for improvement, a sizable portion did not acknowledge any. Further, university representatives did not distinguish between services provided for dating violence and sexual assault.
Ruffs in rough times

De Kemphaan, Philomachus pugnax, een steltloper die in het binnenland van Eurasie broedt en in West Afrika overwintert is sterk in aantal afgenomen. Op basis van een lange termijn ring-terugvangprogramma in een belangrijke voorjaars pleisterplaats in de Noord-Nederlandse graslanden, wilden we inzicht verkrijgen in de mechanismen die de aantalsafname veroorzaakten. Noorwaarts trekkende Kemphanen die in Nederland pleisteren namen af van 20000 in eind 1990 tot 5000 in 2008, waarna hun aantal stabiliseerde. De restpopulatie is heterogeen. De meeste kemphanen overwinteren in draslanden ten zuiden van de Sahara en gebruiken gedurende de trek naar het noorden waarschijnlijk landbouwgrond en rijstvelden, zij vliegen niet linea recta terug. Voor de kleine populatie mannen die in Europa overwintert is Nederland ook een belangrijke pleisterplaats. Lagere jaarlijkse overleving van de meest aan Nederland trouwe vrouwelijke pleisteraars suggereren selectieve sterfte van vrouwen, mogelijk door kwetsbaarheid voor de jacht in Afrika en veranderende landbouwpraktijken langs hun trekweg. De intensivering van het graslandbeheer heeft repercussies voor de opvetsnelheid van Kemphanen in alle fasen van hun trek. Lokaal hebben we een verschuiving van de fourageergebieden van de Kemphanen vastgesteld richting nieuw gecreeerd binnenlands drasland. We toonden aan dat Kemphanen daar graag voedselzoeken, en dat ze gedurende de dag visuele stimuli gebruiken om regenwormen in de bovenste laag van de bodem te detecteren. Regenwormen, maar ook insecten bepalen waarschijnlijk in belangrijke mate de haalbare opvetsnelheid voor de Kemphaan. Daarom is duurzaam beheer van land en water cruciaal voor de bescherming van de Kemphaan en andere binnenlandse trekkende steltlopers.
An Analysis of Professional Adult Education Programs in Northwest Arkansas

Professional adult education (PAE) has been described as structured educational activities that are designed or intended to support the continuing development of professional or career skills, knowledge, competencies, and abilities. Previous research has shown that professional adult education is a vehicle for adult learners to continue their education and gain valuable skills which can aide in career mobility. Given the importance of professional adult education as it relates to further development of adult learners, the purpose for conducting this study was to develop a profile of professional adult education providers and programming offered in Northwest Arkansas. In order to develop this profile, the study utilized a case study research design. Internet searches, along with interviews of local professional adult education providers, were conducted to collect data. The study examined Northwest Arkansas adult education providers, characteristics of programming offered, how programming needs are identified and sustained, programming thematically linked to the region, and implications for state and local policy. The findings suggest there are a variety of non-profit and for-profit adult education providers in the region, management and leadership development programming is the most widely offered program type, there are unique professional adult education offerings in the area targeted to the local workforce, and there is programmatic duplication. The results are important for professional adult education providers looking to evaluate the landscape of professional adult education in Northwest Arkansas. The results also improve learning access for adult learners.
Wireless Multihop Communications for First Responder Connectivity

First responders, using current radio communication technologies, entering a large building can lose radio communications with their incident command due to propagation loss of the radio signal with distance and obstruction. Multihop wireless networks, using intermediate nodes to relay the signal over multiple, shorter hops from source to the destination, have generally been proposed as a means of extending radio coverage. In this thesis we demonstrate real-time deployment of a multihop network to maintain communications between incident command and a first responder entering a building. The system continuously assesses the channel and determines when a new relay needs to be deployed. As the first responder moves deeper into a building, a communications link is automatically configured over which data traffic is transmitted end-to-end. In addition to the deployment algorithm we present how power control of the relay nodes can be used to maintain good radio link quality. To access the network we present a routing protocol, which is particularly adapted for this type of fast changing ad-hoc network. The prototype system of this thesis is implemented on 900 MHz Crossbow mica2 motes supporting periodic transmission of sensor values (e.g., vital signs of the first responder) to the incident command as well as two-way text messaging and Radio Frequency Identification (RFID) information captured by the first responder. We evaluate the prototype system inside a common American five floor office building. The achieved results show that the proposed system is well suited for first responder connectivity.
Educational use of information and communications technology: teachers’ perspective

This study investigated teachers’ perceptions about how information and communications technology (ICT) is being incorporated into teaching and learning, the level of teachers’ digital competence and what factors, in their opinions, might be hindering the use of ICT in schools. A total of 292 Finnish teachers took part in the survey. Activity Theory was chosen for a pedagogical framework. Descriptive statistics, frequency distribution, cross-tabulation and thematic analysis were used to analyse the data statistically. Conclusions include that teachers who have advanced ICT competence use ICT frequently in education. The majority of teachers do not have the means or knowledge to fully use ICT in promoting learning. There still are contradictions between the formal structures of educational institutions and daily classroom practices.
