IP Geolocation databases are widely used in online services to map end-user IP addresses to their geographical location. However, they use proprietary geolocation methods, and in some cases they have poor accuracy. We propose a systematic approach to use reverse DNS hostnames for geolocating IP addresses, with a focus on end-user IP addresses as opposed to router IPs. Our method is designed to be combined with other geolocation data sources. We cast the task as a machine learning problem where, for a given hostname, we first generate a list of potential location candidates, and then we classify each hostname and candidate pair using a binary classifier to determine which location candidates are plausible. Finally, we rank the remaining candidates by confidence (class probability) and break ties by population count. We evaluate our approach against three state-of-the-art academic baselines and two state-of-the-art commercial IP geolocation databases. We show that our work significantly outperforms the academic baselines and is complementary and competitive with commercial databases. To aid reproducibility, we open source our entire approach and make it available to the academic community.

AbstractNeoplasms of the urachus are exceedingly rare, representing 0.17% of all bladder cancers. The mucinous cystic tumor of low malignant potential (MCTLMP) subtype is particularly rare with just 25 previous cases reported in the literature. Although rare, MCTLMPs are important to identify due to potential devastating complications and good cure rates with surgical removal. We present a 43 year old female with a nuanced constellation of comorbidities and confirmed MCTLMP following a workup for abdominal pain and irritative lower urinary tract symptoms. Notably, this tumor did not change in size over a 3-year course of serial imaging prior to surgical excision. This urachal MCTLMP represents roughly the 26th and one of the smallest of its subtype reported in the literature. This case illustrates the diagnosis and management of this rare urachal MCTLMP. Individual patient medical history, clinical considerations, and neoplasm characteristics are examined. Although rare, the potential for increased malignancy and potential complications necessitates surgical management and further investigation by the academic community.

Arrogant individuals are individuals who tend to position themselves in the center, both in their daily lives and in organizational life, and their relationships with others. While they exaggerate their importance, they tend to take over success in any case. Arrogance, which has the potential to adversely affect the organizational climate, can turn into an obstacle to the state of collective engagement and have a devastating effect on the science discipline, for example, in the academic community. In this context, this study aims to examine the arrogance orientations of academicians working in universities, which are higher education organizations. For this purpose, phenomenology, which is a qualitative research design, was used, and thirteen participants consisting of undergraduate and graduate students and graduates were reached with the maximum variation sampling method. The data obtained through focus group interviews using semi-structured questions were analyzed in terms of content using the Maxquda qualitative data analysis program. Findings obtained as a result of the analyses reveal that the arrogance orientations of academicians were gathered under the dimensions of individuality, comparison, contempt, and discrediting. Based on these results, it is possible to indicate that it affects the academic organization climate negatively and feeds on individuality. In this context, it can contribute to reducing the potentially destructive effects of arrogance by encouraging collective work in academic organizations.

The Brassicaceae plant family contains many economically important crops such as Brassica napus L., Brassica rapa L., Brassica oleracea L., Brassica juncea L., Eruca sativa Mill., Camelina sativa L. and Raphanus sativus L. Insufficient data on the genetic regulation of agronomic traits in these species complicates the editing of their genomes. In recent years, the attention of the academic community has been drawn to anthocyanin hyperaccumulation. This trait is not only beneficial for human health, but can also increase plant resistance to stress. MYB transcription factors are the main regulators of flavonoid biosynthesis in plants. Some of them are well studied in Arabidopsis thaliana. The AtMYB60 gene is a transcriptional repressor of anthocyanin biosynthesis, and it also negatively impacts plant responses to drought stress. Myb60 is one of the least studied transcription factors with similar functions in Brassicaceae. There is a high degree of homology between predicted MYB60 genes of A. thaliana and related plant species. However, functions of these homologous genes have never been studied. Gene knockout by CRISPR/Cas technology remains the easiest way to perform genome editing in order to discover the role of individual plant genes. Disruption of genes acting as negative regulators of anthocyanin biosynthesis could result in color staining of plant tissues and an increase in stress tolerance. In the present study, we investigated the AtMYB60 gene and its homologs in Brassicaceae plants and suggested universal gRNAs to knockout these genes.

The academic community frequently engages with OpenStreetMap (OSM) as a data source and research subject, acknowledging its complex and contextual nature. However, existing literature rarely considers the position of academic research in relation to the OSM community. In this paper we explore the extent and nature of engagement between the academic research community and the larger communities in OSM. An analysis of OSM-related publications from 2016 to 2019 and seven interviews conducted with members of one research group engaged in OSM-related research are described. The literature analysis seeks to uncover general engagement patterns while the interviews are used to identify possible causal structures explaining how these patterns may emerge within the context of a specific research group. Results indicate that academic papers generally show few signs of engagement and adopt data-oriented perspectives on the OSM project and product. The interviews expose that more complex perspectives and deeper engagement exist within the research group to which the interviewees belong, e.g., engaging in OSM mapping and direct interactions based on specific points-of-contact in the OSM community. Several conclusions and recommendations emerge, most notably: that every engagement with OSM includes an interpretive act which must be acknowledged and that the academic community should act to triangulate its interpretation of the data and OSM community by diversifying their engagement. This could be achieved through channels such as more direct interactions and inviting members of the OSM community to participate in the design and evaluation of research projects and programmes.

Conducting an international research study may bear various challenges; however, during the global COVID-19 crisis, such a study undertakes unpredictable trajectories. This paper explores the challenges experienced by researchers studying Syrian refugees’ physical and mental health and aid workers serving under humanitarian organizations in Lebanon. It includes information about the changes in the study’s goals and design with the emergence and spread of SARS-CoV-2, as necessitated by the circumstances COVID-19 imposed. It focuses on the unique perspectives of the research team of two students and their mentor who faced multiple challenges while involved in the study, and their narratives and subjective experiences that led to new opportunities for growth in the project. The research team specifically engaged in humanistic and existential psychology in order to conduct research in a manner conducive to personal and professional development, productivity and growth. To conclude, the researchers propose recommendations to the academic community on mitigating some of the challenges faced when conducting international research, and suggestions to the humanitarian sector serving vulnerable populations in conflict zones during COVID-19.

Abstract Background The problems for training in interprofessional education (IPE) of health professionals for this new century are systemic: limitation in competencies for teamwork, persistent stratification of gender relations in the status of health workers, a focused emphasis on technical skills, difficulty in analysis and understanding of broader problematic issues of the context, sporadic instead of continuous care, quantitative and qualitative imbalances in the professional labor market, and fragility in leadership skills to improve the performance of the health system. This study evaluated the perception of students and teachers of health area courses at a private university in São Paulo regarding interprofessional education. Methods A sociodemographic questionnaire to delineate the participants’ profile and the RIPLS questionnaire that assesses the attitudes and perceptions of students and professionals to determine their readiness for interprofessional learning were applied. RIPLS is proposed to measure the change in attitudes, the effects of different interventions, and the effectiveness of interventions in changing attitudes and perceptions. Results The main results were that training in Medicine and Nursing is easier for interprofessional education than that in Physiotherapy. By comparing the perception of the academic community regarding gender, we find that participating women are more available for teamwork and collaborative practices. Conclusion To improve the perception of students and teachers in collaborative practice, the need for a teacher training program on IPE principles and an early and more frequent insertion of IPE practices in the curricula of courses is evident.

Informed by the poststructuralist theory, this study investigates the case of Ming, a Chinese professor of English, about the impacts of his first language (L1) and second language (L2) learning experience, and the changes of social contexts on his L1 and L2 identities construction. It was found that being a learner of English as a Foreign Language (EFL), Ming’s identities development aligned with the poststructuralist theory, in which it is considered dynamic, fluid and conflicting. Ming negotiated and renegotiated his identities in various social contexts in China and the United States and finally gained acceptance into the L2 academic community. This study not only analyzes Ming’s experience with his language learning and identities, but also unravels that conflicts may be part of the process of identities construction, and encourages learners to be persistent and emotionally resilient, while using certain strategies to retain a stable L1 identity so that they can navigate through the negative encounters during the second language acquisition (SLA) process to sustain the development of their identities and L2 abilities.
