Pull request latency evaluation is an essential application of effort evaluation in the pull-based development scenario. It can help the reviewers sort the pull request queue, remind developers about the review processing time, speed up the review process and accelerate software development. There is a lack of work that systematically organizes the factors that affect pull request latency. Also, there is no related work discussing the differences and variations in characteristics in differentarXiv:2108.09946v1 fatcat:zzsagpa2y5betbpuha6rtco4k4

Then we assessed their relative importance in five scenarios and six different contexts using the mixed-effects linear regression model. We find that the relative importance of factors differs in different scenarios, e.g., the first response time of the reviewer is most important when there exist comments. Meanwhile, the number of commits in a pull request has a more significant impact on pull request latency when closing than submitting due to changes in contributions brought about by the review process.
Chest wall primitive neuroectodermal tumor (PNET) is a rare tumor necessitating a prompt diagnosis. Unfortunately, the diagnosis of this tumor can be extremely challenging and misdiagnosis is at times unavoidable. Case Report: Here we present one such rare case of chest wall PNET. Patient initially had complaints of pain and lump in the right breast. Contrast enhanced computed tomography (CECT) of thorax showed large mass with both intra-thoracic and extra-thoracic extension.

Later patient was treated with induction chemotherapy with alternating VAC/IE followed by right chest wall resection. Post-operative histopathology was suggestive of complete pathological response. 18 FDG PET-CT done subsequently was suggestive of complete metabolic response. Conclusion: Chest wall PNETs may mimic as breast lump, posing diagnostic dilemma. Multimodality treatment may yield excellent outcome as in our case.
Personality plays a pivotal role in our understanding of human actions and behavior. Today, the applications of personality are widespread, built on the solutions from psychology to infer personality. In software engineering, for instance, one widely used solution to infer personality uses textual communication data. As studies on personality in software engineering continue to grow, it is imperative to understand the performance of these solutions. This paper compares the inferential abilityarXiv:2107.05829v2 fatcat:w364ryjr6jep5odrptjimq22dy

We explore the challenges and potential solutions to improve the inferential ability of personality tests. Our study shows that solutions for inferring personality are far from being perfect. Software engineering communications data can infer individual developer personality with an average error rate of 41%. In the best case, the error rate can be reduced up to 36% by following our recommendations.
The Delta Maintainability Model: Measuring Maintainability of Fine-Grained Code Changes - 2nd International Conference on Technical Debt (TechDebt 2019) - Montréal, Canada - May 26–27, 2019 Technical Report for the paper and dataset available at: https://zenodo.org/record/2542535doi:10.5281/zenodo.2606632 fatcat:xlazrjqozjclxecyuttexjdh6e
Existing maintainability models are used to identify technical debt of software systems. Targeting entire codebases, such models lack the ability to determine shortcomings of smaller, fine-grained changes. This paper proposes a new maintainability model -the Delta Maintainability Model (DMM) -to measure fine-grained code changes, such as commits, by adapting and extending the SIG Maintainability Model. DMM categorizes changed lines of code into low and high risk, and then uses the proportion ofdoi:10.1109/techdebt.2019.00030 dblp:conf/icse/BiaseRBD19 fatcat:fxdgjekztrcp3bp6mp2y4nofue

The goal of the DMM is twofold: first, producing meaningful and actionable scores; second, compare and rank the maintainability of fine-grained modifications. We report on an initial study of the model, with the goal of understanding if the adapted measurements from the SIG Maintainability Model suit the fine-grained scope of the DMM. In a manual inspection process for 100 commits, 67 cases matched the expert judgment. Furthermore, we report an exploratory empirical study on a data set of DMM scores on 3,017 issue-fixing commits of four open source and four closed source systems. Results show that the scores of DMM can be used to compare and rank commits, providing developers with a means to do root cause analysis on activities that impacted maintainability and, thus, address technical debt at a finer granularity.

In the face of chronic and emerging resistance of parasites to currently available drugs and constant need for new anti-malarials, natural plant products have been the bastion of anti-malarials for thousands of years. Moreover natural plant products and their derivatives have traditionally been a common source of drugs, and represent more than 30% of the current pharmaceutical market. The present study shows evaluation of anti-malarial effects of compound conessine isolated from plantdoi:10.1186/1475-2875-12-194 pmid:23758861 pmcid:PMC3685520 fatcat:mgdc7q5eqrc4tafhakqajqqxzm

Methods: In vitro anti-plasmodial activity of compound was assessed using schizont maturation and parasite lactate dehydrogenase (pLDH) assay. Cytotoxic activities of the examined compound were determined on L-6 cells of rat skeletal muscle myoblast. The four-day test for anti-malarial activity against a chloroquine-sensitive Plasmodium berghei NK65 strain in BALB/c mice was used for monitoring in vivo activity of compound. In liver and kidney function test, the activity of alkaline phosphatase (ALP) was examined by p-NPP method, bilirubin by Jendrassik and Grof method. The urea percentage was determined by modified Berthelot method and creatinine by alkaline picrate method in serum of mice using ENZOPAK/CHEMPAK reagent kits. Results: Compound conessine showed in vitro anti-plasmodial activity with its IC 50 value 1.9 μg/ml and 1.3 μg/ml using schizont maturation and pLDH assay respectively. The compound showed cytotoxity IC 50 = 14 μg/ml against L6 cells of rat skeletal muscle myoblast. The isolated compound from plant H. antidysenterica significantly reduced parasitaemia (at 10 mg/kg exhibited 88.95% parasite inhibition) in P. berghei-infected mice. Due to slightly toxic nature (cytotoxicity = 14), biochemical analysis (liver and kidney function test) of the serum from mice after administration of conessine were also observed. Conclusion: The present investigation demonstrates that the compound conessine exhibited substantial antimalarial property. The isolated compound could be chemically modified to obtain a more potent chemical entity with improved characteristics against malaria.

Results and Conclusion We observed structural differences in pull request acceptance rates across 17 countries. Countries with no apparent similarities such as Switzerland and Japan had one of the highest pull request acceptance rates while countries like China and Germany had one of the lowest pull request acceptance rates. Notably, higher acceptance rates were observed for all but one country when pull requests were evaluated by developers from the same country.
The appeal of delivering new features faster has led many software projects to adopt rapid releases. However, it is not well understood what the effects of this practice are. This paper presents an exploratory case study of rapid releases at ING, a large banking company that develops software solutions in-house, to characterize rapid releases. Since 2011, ING has shifted to a rapid release model. This switch has resulted in a mixed environment of 611 teams releasing relatively fast and slow.

We followed a mixed-methods approach in which we conducted a survey with 461 participants and corroborated their perceptions with 2 years of code quality data and 1 year of release delay data. Our research shows that: rapid releases are more commonly delayed than their non-rapid counterparts, however, rapid releases have shorter delays; rapid releases can be beneficial in terms of reviewing and user-perceived quality; rapidly released software tends to have a higher code churn, a higher test coverage and a lower average complexity; challenges in rapid releases are related to managing dependencies and certain code aspects, e.g. design debt.

Results obtained for indicators under each thematic area, were then divided into four categories: a) ≥90 % -good, b) 70-90%-fair, c) 50-70 % -average and d) < 50 % -poor. Setting: The review was undertaken in five high-priority states -Bihar, Madhya Pradesh, Maharashtra, Rajasthan and Uttar Pradesh. Four districts were selected base on a scoring criterion from each state. Results: The programme implementation was found average ranging from 53.6 % to 63.8 % and the mechanism of vaccine logistic and cold chain was fair ranging from 71.0 % to 79.4 % across all the states. The mechanism of data recording and reporting was poor in Madhya Pradesh (36.8 %) and Maharashtra (47.0 %) and average in the remaining three states. Programme communication needs considerable improvement. Except Madhya Pradesh (62.4 %), the communication activities were poor in the other four states. Conclusion: The methodology of the review will help in identifying critical gaps and strengths in the immunization processes and in formulating an immunization coverage improvement plan (ICIP) in the states.
