A Large Scale Study of Long-Time Contributor Prediction for GitHub Projects

The continuous contributions made by long time contributors (<italic>LTCs</italic>) are a key factor enabling open source software (OSS) projects to be successful and survival. We study <sc>Github</sc> as it has a large number of OSS projects and millions of contributors, which enables the study of the transition from newcomers to <italic>LTCs</italic>. In this paper, we investigate whether we can effectively predict newcomers in OSS projects to be <italic>LTCs</italic> based on their activity data that is collected from <sc>Github</sc>. We collect <sc>Github</sc> data from GHTorrent, a mirror of <sc>Github</sc> data. We select the most popular 917 projects, which contain 75,046 contributors. We determine a developer as a <italic>LTC</italic> of a project if the time interval between his/her first and last commit in the project is larger than a certain time <inline-formula><tex-math notation="LaTeX">$T$</tex-math><alternatives><mml:math><mml:mi>T</mml:mi></mml:math><inline-graphic xlink:href="xia-ieq1-2918536.gif"/></alternatives></inline-formula>. In our experiment, we use three different settings on the time interval: 1, 2, and 3 years. There are 9,238, 3,968, and 1,577 contributors who become <italic>LTCs</italic> of a project in three settings of time interval, respectively. To build a prediction model, we extract many features from the activities of developers on <sc>Github</sc>, which group into five dimensions: developer profile, repository profile, developer monthly activity, repository monthly activity, and collaboration network. We apply several classifiers including naive Bayes, SVM, decision tree, kNN and random forest. We find that random forest classifier achieves the best performance with AUCs of more than 0.75 in all three settings of time interval for <italic>LTCs</italic>. We also investigate the most important features that differentiate newcomers who become <italic>LTCs</italic> from newcomers who stay in the projects for a short time. We find that the number of followers is the most important feature in all three settings of the time interval studied. We also find that the programming language and the average number of commits contributed by other developers when a newcomer joins a project also belong to the top 10 most important features in all three settings of time interval for <italic>LTCs</italic>. Finally, we provide several implications for action based on our analysis results to help OSS projects retain newcomers.
Western Mediterranean Subcontinental Mantle Emplacement by Continental Margin Obduction

Obduction is the tectonic process that results from thrusting of an oceanic lithosphere section (ophiolite) onto a continent. In contrast, thrusting of subcontinental mantle, observed in several mountain belts, remains a major unknown of plate tectonics. In the western Mediterranean, the Ronda and Beni Bousera peridotites are the largest worldwide subcontinental mantle exposure. From a geological point of view, the Ronda peridotites are exhumed by hyperstretching of the continental lithosphere in a back‐arc immediately followed by thrusting, explaining their present‐day position inside the Alboran crust. Using 2‐D and 3‐D modeling of new gravimetric data combined with local seismic tomography, we show that the Ronda peridotites are rooted inside the Alboran mantle along the entire Gibraltar arc. On these bases, we propose that the emplacement of the Ronda peridotites occurred in a back‐arc setting and corresponds to the thrusting of an entire hyper‐stretched continental margin onto a continent, a process that we define as continental margin obduction. This results from two successive deformation events: continental upper plate extension driven by slab roll‐back, immediately followed by upper plate shortening, likely triggered when a buoyant continental domain enters the subduction. We propose that this process affected the entire western Alboran domain, with peridotite bodies embedded within the crust along the whole Gibraltar Arc. We suggest that other examples such as the Alps Ivrea mantle body could likely represent continental margin obduction at the onset of continental collision.
A Grounded Theory of Music Teacher Large Scale Conference Professional Development Implementation

The purpose of this study was to understand the process of music teacher large-scale conference professional development (PD) implementation (i.e., the integration of conference-derived learnings into classroom practice). The context of this investigation was two national music conferences, the Midwest Clinic and the National Association for Music Education National In-Service Conference, and one state music conference, the Texas Music Educators Association Clinic/Convention. Using purposive maximum variation sampling, active music teachers (n = 32) who each attended one of these conferences were recruited. Data collection occurred in a series of three participant interview phases, staggered according to which conference participants attended and when each conference was held. Twenty-eight participants were interviewed twice, and four participants were interviewed once, yielding a total of 60 interview transcripts, which were then openly, axially, and selectively coded in accordance to grounded theory method. The principal finding, the cycle of music teacher large scale conference professional development implementation (C-MTPDI), revealed an implementation process in three phases. First, the consideration phase (before/during conference) entailed needs assessment, direct engagement, change articulation, and, for some participants, deterrent factors/contingencies. Second, the realization phase (immediate post-conference) included translation, integration, and recalibration. Third, and finally, the decision phase (3-5 weeks post-conference) included evaluation. The core category, or main theme of the research, was seeking convergence: relevance, practicability, and impact. Contextual conditions included PD worldview and PD policy environment. Avenues for future scholarship include clarifying differences in design and effectiveness among and within music-specific PD models, more fully understanding the status of large-scale conference PD in music education and its effect on practice, and theorizing PD implementation in non-conference contexts. Practical implications include developing new theory-aligned PD policies, putting into place more robust infrastructures of implementation support for large-scale conference attendees, addressing PD funding inequities between teachers in music and non-music disciplines, and helping practitioners to newly conceive "one-off" PD events (e.g., large-scale conferences) as sustainable investments in long-range professional growth.

RLWE-Oriented High-Speed Polynomial Multiplier Utilizing Multi-Lane Stockham NTT Algorithm

Cryptography based on ring learning with error (RLWE) problem has become increasingly popular due to its resistance against quantum analysis. The most time-consuming operation in RLWE cryptosystem is polynomial multiplication. This brief presents a novel polynomial multiplier based on Stockham fast Fourier transform (FFT) algorithm. We propose a multi-lane number theoretic transform (NTT) algorithm which can achieve <inline-formula> <tex-math notation="LaTeX">${n}$ </tex-math></inline-formula>-degree polynomial multiplication in <inline-formula> <tex-math notation="LaTeX">${(nlgn)/d+2n/d}$ </tex-math></inline-formula> clock cycles with <inline-formula> <tex-math notation="LaTeX">${d}$ </tex-math></inline-formula> lanes of butterfly units. In addition, we also customize a memory addressing strategy and a round constant managing scheme for the proposed multi-lane NTT algorithm. Based on our proposed algorithm, a high-speed polynomial multiplier is accomplished on FPGA platform. Implementation results on Spantan-6 FPGA show that our proposed algorithm can achieve a speed up factor of no less than 2.7 times compared with the state of art designs.

Comparison of Body Composition Two Months after High Caloric-Tofu Intake and Body Composition Six Months after the Experiment—In the Case of Elderly People

Japan becomes the super aged society. It is expected from now on that the population of the elderly person increases more and more. Therefore, disease prevention such as sarcopenia and frailty in the elderly person is required. This study tried the improvement of meal contents by taking in soy protein using caloric-tofu in daily life. The ten elderly people (one man, 9 women: from age 55 years old to 83 years old) who submitted the written consent of the subject participated in this study. We performed the gene analysis (β3AR, UCP1, β2AR) of the subject. The subject lived a normal life every day. The subject had eaten two high caloric-tofu a day. A caloric-tofu has 100 kcal. The subject participated in a study for two months. As for the subject, body composition was measured on the first day and two months after the start of the experiment, and six months after the end of the experiment. As a result, skeletal muscle rates of five people increased slightly, and body fat rate decreased slightly. However, five people changed into neither the skeletal muscle rate nor the body fat rate. Six months after the end of the experiment, the pair composition results were kept almost the same as at the end of the experiment. It can be highly appreciated that in the effective group, the pair composition could be maintained in a better condition than at the beginning of the experiment. For elderly people, the effective group, it is significant that intake of high caloric-tofu is effective in increasing the rate of skeletal muscle, and the effect is maintained even after half a year.
Innovation Through Linkage, Leverage, and Learning: The Case of Monk Fruit Corporation

Abstract This study investigates the role of Chinese-foreign linkages in the innovation trajectory of Guilin GFS Monk Fruit Corporation (Monk Fruit Corp.). Using the linkage-leverage-learning (LLL) framework as our starting point for analysis and integrating complementary theory, we build a relationally and contextually oriented framework for assessing innovation. Longitudinal analysis of archival data, and insights from key respondents, demonstrates that the firm’s innovative and organizational development is inextricably entwined with the process of learning, achieved overtime by leveraging linkages with both domestic and foreign partners. The results also reveal how independent research and development (R&D), coupled with skill in relationship building, applied by the Chinese firm and the individuals within it, can provide an equally important support structure to Sino-foreign innovation. Our results reaffirm the importance of collaboration, but also demonstrate its limits as collaborative organizational relationships evolve from being socially to equity-based over time.
Research Article 1: Towards a Public Health Model of Child Protection in Australia

Most current child protection systems in Australia are unsustainable and potentially harmful. It is time to reconsider the direction in which child protection policy is heading in this country. To this end we need to understand the historical processes that have led to the current situation, explore the potential of a public health approach to child protection, enhance the capacity to translate research into policy and practice, and transplant effective and sustainable innovations on a system-wide basis.

Assessment of Knowledge, Attitudes and Practices Related to Contraceptive Use among Teenagers in High Schools and Colleges in Dakar, Senegal

Introduction: In Senegal, adolescents aged 10 to 19 years represent 22.9% of the total population. The unmet need for contraception in this part of the population remains high despite the health interventions implemented to promote their sexual health. The aim of this study is to analyze the practice of modern contraception in schools in Dakar high schools in Senegal during the year 2018. Methods: A cross-sectional study was conducted in high schools and colleges in Dakar from March 1 to April 30, 2018. This study involved 452 students. This was a self-administration of the questionnaires. After univaried and bivaried analyses, a multivariate logistic analysis identified the factors associated with students’ use of modern contraception. Results: The prevalence of modern contraceptive use among students is 8.84%. Factors associated with the use of modern contraceptive methods among students were age over 18 years (AR: 4.7, 95% CI [1.02 - 22.5]), male sex (AR: 27.8, 95% CI [6.8 - 100.0]), secondary school level (AR: 10.6, 95% CI [2.1 - 53.0]), access to a youth socio-educational home (AR: 3.9, 95% CI [1.1 - 14.9]) and having a child (AR: 25.6, 95% CI [2.2 - 100.0]). Conclusion: Our results concluded that modern contraceptive needs were better met among older male students, those who had an unfortunate experience of unwanted pregnancy and those attending school’s youth socio-educational homes. This suggests shortcomings in the promotion of sexual health among younger students, particularly those in the secondary grades.
ISL-1: a new potential marker of stem/progenitor cells in the developing human uterus

The human uterus is a highly dynamic organ with peculiar plasticity and marked reproductive ability, due to the presence of a vast number of multiple stem/progenitor cell types, including endometrial, stromal and vascular progenitor cells. Conflicting results have been published regarding which uterine population might represent the real stem/progenitor cell fraction in terms of in vivo stem cell activity. Human endometrial side population (ESP) cells were shown to differentiate into multiple endometrial lineages in the stem cell niche provided by whole endometrial cells, suggesting that ESP cells might represent the most important stem/progenitor cells responsible of the cyclical regeneration of the endometrium throughout a woman’s reproductive life. This study was aimed at analyzing the localization, composition, and occurrence of stem cell niches in the human fetal uterus at different stages of development. To this end, the whole uterus was obtained at autopsy by 12 human fetuses and newborns, ranging in gestational age from 12 up to 39 weeks of gestation. Tissue paraffin sections were immunostained with antibodies against insulin gene enhancer protein (ISL-1), a transcription factor previously utilized as a marker of stem/progenitor cells in the pancreas, heart and nervous system. Reactivity for ISL-1 was detected in both epithelial and stromal uterine precursors, at all gestational ages, allowing the detection of uterine progenitor cells. The loss of reactivity for ISL-1 in some stromal cell precursors was interpreted as a sign of differentiation. These preliminary data indicate ISL-1 as a useful marker for the detection of stem/progenitor cells in the human fetal endometrium. Further studies are needed to verify the utility of ISL-1 as a marker of stem/progenitor cells in the adult endometrium.
The Gender Gap in International Trade: Female-run Firms and the Exporter Productivity Premium

Female-run firms are less likely to be exporters although they exert positive influence in various aspects in an economy and society. With a new and comprehensive data set on manufacturing plants, I investigate the exporter productivity premium of female-run firms in Germany. The results show that female-run firms gain a higher exporter-productivity premium than male-run firms. I find evidence for selection into exporting but no impact for learning from exporting for female-run exporting firms. These results give hint to discrimination barriers that female-run firms face when they are exporting as compared to male-run firm exporters.
The Serum Levels of CCL2 and CCL16 Expression in Patients with Irritable Bowel Syndrome.

Background Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder characterized by altered bowel habits and abdominal pain in the absence of a recognizable structural anomaly. The pathogenesis of IBS has been associated with inflammation and the expression of pro-inflammatory chemokines, such as CCL2 and CCL16. Our study aimed to investigate the relationship between the serum levels of CCL2 and CCL16 and IBS. Additionally, we examined how serum levels of these chemokines relate to IBS subtypes. Methods Patients with IBS diagnosed according to the Rome III criteria participated in this study (n= 96). Healthy individuals with no history of allergic, autoimmune, chronic or active gastrointestinal infectious diseases were used as controls (n= 44). The serum levels of CCL2 and CCL16 was measured via enzyme-linked immunosorbent assay (ELISA). Results A significant decrease in the serum levels of CCL16 and CCL2 was observed in the patients with IBS. Additionally, the serum levels of CCL16 in IBS patients with diarrhea (D-IBS) was significantly higher than those with the mixed IBS (M-IBS) subtype. Conclusion The significant increase in the serum levels of CCL-16 in patients with D-IBS compared to patients with M-IBS suggests that CCL-16 may be used as an immunological biomarker to differentiate between these two subtypes.
Moroccan Arabic: The Battlefield of Language Ideologies

The debate on the use of Moroccan Arabic (also known as Moroccan darija) dates back to the medieval period when literary critics have discussed the effectiveness of writing in Moroccan Arabic lyrics of Muslim Spain, muwashshahat and zajal. This debate was later sharpened in the protectorate era (1912-1955) by the French colonial administration in its attempt to use MA in education as a tool to divide Morocco into Arabs and Amazigh, separate the country from the Arab world and pave the way for French to flourish in society. Nowadays, the use of MA in education came to the fore front of the interests of Moroccan intelligentsia. A new current of Francophone academics called for the legitimacy of using MA in education and media to fight illiteracy and maximize access to education in the country. They held many conferences for the sake of discussing the utility of MA as an alternative for SA in education and designed dictionaries and books to ease its instruction. Such attempts raised the hostility of Arabists and Amazigh activists. They regarded the defense of MA use in education as an ideology of language to eradicate Moroccan official languages in favor of French and the Francophone culture. The present empirical research examines the status of MA in education and the different ideologies backing its use by Moroccan teachers and students.
