Geolocation Prediction in Twitter Using Social Networks: A Critical Analysis and Review of Current Practice
Authors: Jurgens David , Finethy Tyler , McCorriston James , Xu Yi , Ruths Derek 
Published: November 2022

Geolocated social media data provides a powerful source of information about place and regional human behavior. Because little social media data is geolocation-annotated, inference techniques serve an essential role for increasing the volume of annotated data. One major class of inference approaches has relied on the social network of Twitter, where the locations of a user's friends serve as evidence for that user's location. While many such inference techniques have been recently proposed, we actually know little about their relative performance, with the amount of ground truth data varying between 5% and 100% of the network, the size of the social network varying by four orders of magnitude, and little standardization in evaluation metrics. We conduct a systematic comparative analysis of nine state-of-the-art network-based methods for performing geolocation inference at the global scale, controlling for the source of ground truth data, dataset size, and temporal recency in test data. Furthermore, we identify a comprehensive set of evaluation metrics that clarify performance differences. Our analysis identifies a large performance disparity between that reported in the literature and that seen in real-world conditions. To aid reproducibility and future comparison, all implementations have been released in an open source geoinference package.
An Analysis of Exercising Behavior in Online Populations
Authors: Jurgens David , McCorriston James , Ruths Derek 
Published: November 2022

Exercise plays a central role in many peoples' fitness goals. While prior work has examined how individuals pursue these health and fitness goals on general purpose platforms such as Twitter, the lack of precise activity recording has limited detailed analyses of individual and group behaviors. In this study, we explore a recent social media platform dedicated to exercise and use nearly four years of longitudinal exercising history of over 188,000 users to discover large-scale exercising patterns corresponding to different motivations such as sports or general fitness.

Authors: Ghosh Priyankar , Chakrabarti P. , Dasgupta Pallab 
Published: November 2022

In this paper we consider finding solutions for problems represented using AND/OR graphs, which contain tasks that can fail when executed. In our setting each node represent an atomic task which is associated with a failure probability and a rollback penalty. This paper reports the following contributions - (a) an algorithm for finding the optimal ordering of the atomic tasks in a given solution graph which minimizes the expected penalty, (b) an algorithm for finding the optimal ordering in the presence of user defined ordering constraints, and (c) a counter example showing the lack of optimal substructure property for the problem of finding the solution graph having minimum expected penalty, and a pseudo-polynomial algorithm for finding the solution graph with minimum expected penalty.
Motion Planning With Differential Constraints as Guided Search Over Continuous and Discrete Spaces
Authors: Plaku Erion 
Published: November 2022

To compute a motion trajectory that avoids collisions, reaches a goalregion, and satisfies differential constraints imposed by robotdynamics, this paper proposes an approach that conducts a guidedsearch over the continuous space of motions and over a discrete spaceobtained by a workspace decomposition. A tree of feasible motions anda frontier of workspace regions are expanded simultaneously by firstdetermining the next region along which to expand the search and thenusing sampling-based motion planning to add trajectories to the treeto reach the selected region. When motion planning is not able toreach the selected region, its cost is increased sothat the approach has the flexibility to expand the search along newregions. Comparisons to related work show significant computationalspeedups.
Mário de Sá-Carneiro nas publicações periódicas do Modernismo: ‘impressões de guerra’/ Mário de Sá-Carneiro in the periodicals of Modernism: ‘impressions of war’
Authors: Marques Ricardo 
Published: November 2022

Resumo: O presente trabalho pretende analisar a importância de Mário de Sá-Carneiro nas publicações periódicas do seu tempo. Começando por fazer um voo rasante entre o estado da arte deste tópico e a participação do poeta português em revistas literárias, falaremos, nomeadamente, da sua colaboração, durante a guerra, com A Restauração e Ilustração Portuguesa. O primeiro destes dois periódicos tem uma duração efémera no início da primeira guerra mundial (1914), sendo um diário monárquico que antecede a revista A Ideia Nacional (1915-16) também fundada e dirigida por Homem Cristo Filho. É, no entanto, em Ilustração Portuguesa, por seu turno, que a sua crónica de guerra parece mais desenvolta e interessante. Veremos, enfim, como Sá-Carneiro, residente em Paris, assume a descrição do cenário urbano desta nova guerra envolvendo as maiores potências mundiais, e como isso se relaciona com a sua própria obra literária.Palavras-chave: Mário de Sá-Carneiro; Literatura Portuguesa Moderna; Estudos Modernistas; Periódicos; Primeira Guerra Mundial.Abstract: The present work intends to analyze the importance of Mário de Sá-Carneiro to the periodical publications of his time. Starting with a general view crossing between the state of the art on this topic and the Portuguese poet’s participation in literary magazines, we will talk in particular about his collaboration, during the first world war, with the periodicals A Restauração and Ilustração Portuguesa. The first of these two periodicals had an ephemeral duration at the beginning of the first world war (1914), being a monarchical newspaper that preceded the magazine A Ideia Nacional (1915-16) also founded and directed by Homem Cristo Filho. It is, however, in Ilustração Portuguesa, on the other hand, that his war chronicle seems more resourceful and interesting.We will thus see how Sá-Carneiro, resident in Paris, assumes the description of the urban scenario of this new war involving the major world powers, and how this relates to his own literary work.Keywords: Mário de Sá-Carneiro; Modern Portuguese Literature; Modernist Studies; Periodicals; First World War.
Redefining Violence against Women and Framing Issues
Authors: Kaygisiz Dilse 
Published: November 2022

Previous studies have highlighted the importance of attitudinal and social change in making laws effective in their implementation. Moreover, scholarship on social movements found that one of the drivers of getting demands across the right platforms and being appropriately represented was by framing movements’ goals into collective identities. How can framing issues and the socio-political context explain the progress of women’s movements regarding violence against women?
I argue that in Turkey and the Philippines, women’s movements redefined violence against women as a public issue by contesting the state rhetoric that domestic violence was an ungendered family matter, which led to the passing of protective laws against violence against women and more specifically on domestic violence. However, these movements’ attempts in the two countries to affect policy saw different consequences given the unified agenda that they could follow and the political climate in which they could operate.
Dampak Politik Hukum dan Respon Masyarakat atas Pembaharuan Undang-Undang Minerba
Authors: Al Idrus Nur Fadilah 
Published: November 2022

Undang-Undang No. 4 Tahun 2009 tentang Pertambangan Mineral dan Batubara dianggap masih belum memiliki kemajuan dalam menangani masalah yang terjadi dalam bidang pertambangan di Indonesia. Pembaruan Undang-Undang Minerba menjadi Undang-Undang No. 3 Tahun 2020 diharapkan dapat memperbaiki pertambangan minerba sehingga memiliki partisipasi nyata terhadap masyarakat. Namun RUU yang dirancang tahun 2019 nyatanya mengalami resistensi dari masyarakat. Penelitian ini bertujuan untuk mengetahui bagaimana politik hukum pemerintah dan respon masyarakat atas pembaruan UU Minerba. Penelitian ini dilakukan dengan menggunakan metode penelitian yuridis normatif dengan sumber hukum yang berasal dari peraturan perundang-undangan, buku, jurnal ilmiah dan website. Hasil penelitian menunjukan bahwa politik hukum dalam UU Minerba mengarah pada perkembangan hukum yang praktis serta mendukung sektor pertambangan dan mengatur mengenai hak dan kewajiban serta perlindungan pengusaha pertambangan dan lain sebagainya. Selain itu politik hukum yang terlihat jelas yaitu mengenai pemberian perlindungan ekonomi untuk rakyat dan Negara, sekalipun terdapat kerugian yang ditimbulkan. Poin yang perlu diperhatikan dalam UU Minerba yang baru yaitu terkait kewenangan pengelolaan serta perizinan, perpanjangan izin operasi, hilirisasi atau peningkatan nilai tambah, divestasi, tidak berdasarkan landasan tata ruang, serta pertambangan rakyat, reklamasi dan pasca tambang. Respon masyarakat terkait pembaruan perundangan ini tergolong menjadi dua yaitu pro dan kontra. Pihak pro bernggapan bahwa pembaruan ini lebih jelas dan sesuai. Sedangkan pihak yang kontra beranggapan bahwa regulasi baru terkait minerba hanya untuk kepentingan pemilik modal utama sehingga perlu dilakukan kritik. Selain itu, pembentukan UU ini juga dianggap terlalu kilat dan tidak disertai adanya keterlibatan masyarakat karena dilakukan pada saat wabah Covid-19.
David Ellis: um consultor norte-americano no desenvolvimento de centros e museus de ciências brasileiros
Authors: Norberto Rocha Jessica 
Published: November 2022

Em 2006, quando ainda era uma graduanda na Universidade Federal de Minas Gerais (UFMG), tive a oportunidade de conhecer David Ellis em um evento destinado à discussão sobre a construção e operação de centros e museus de ciências. Como estagiária no Centro de Divulgação Científica (CDC/UFMG) – departamento responsável pela organização do evento e pela construção de dois centros de ciências – eu não imaginava que depois de quinze anos, eu teria a oportunidade de encontrar David novamente no Museum of Science (MOS) em Boston (EUA) onde estive como pesquisadora Fulbright em 2021.
David foi diretor e presidente do MOS de 1990 até 2002. Também foi consultor da Fundação Vitae, no Brasil, auxiliando na construção de centros e museus de ciências com sua experiência em planejamento, desenvolvimento organizacional, captação de recursos, administração e gerência. A Fundação Vitae surgiu em 1984, após a dissolução de um grupo empresarial responsável por mineradoras na América do Sul. Após esta dissolução, a Vitae redirecionou seu foco para pautas sociais. A proposta era estimular um pensamento filantrópico para contribuir com a melhoria da qualidade de vida de comunidades da região, dando apoio no campo da educação, da cultura e promovendo demais pautas sociais.
Em nossa conversa, pudemos fazer uma retrospectiva, resgatar memórias, descrever o legado da Fundação Vitae e entender como o esforço de determinadas pessoas e organizações governamentais ajudou na concepção de novos centros e museus de ciências e no auxílio ao desenvolvimento daqueles já existentes. Na entrevista, David Ellis também comenta os atuais e futuros desafios dos museus de ciência ao redor do mundo e como os EUA e o Brasil podem trabalhar juntos de forma a avançar na missão da educação e comunicação científica no século XXI.

Published: November 2022

Proper vertex coloring c of a graph G is a graceful coloring if c is a graceful k-coloring for k∈{1,2,3,…}. Definition graceful k-coloring of a graph G=(V,E) is a proper vertex coloring c:V(G)→{1,2,…,k);k≥2, which induces a proper edge coloring c':E(G)→{1,2,…,k-1} defined c'(uv)=|c(u)-c(v)|. The minimum vertex coloring from graph G can be colored with graceful coloring called a graceful chromatic number with notation χg (G). In this paper, we will investigate the graceful chromatic number of vertex amalgamation of tree graph family with some graph is path graph, centipede graph, broom and E graph.

L’étude s’est proposé de diagnostiquer le système scolaire du territoire de Mahagi en République Démocratique du Congo (RDC), devant son harmonisation. Le diagnostic révèle qu’il y a des différences significatives entre les chefferies au niveau du taux brut de scolarisation (CV=0,73 > 0,30). Cette différence, génère des déséquilibres quant aux efforts fournis sur l’ensemble du territoire de Mahagi en matière de scolarisation; il s’est avéré également des différences significatives au niveau du taux d’occupation des locaux et de l’encadrement des élèves (0,58>0,30) et non significatives au niveau de la taille d’écoles (CV=0,26 compris entre 0,15 et 0,30). Cependant, le pourcentage d’enseignants qualifiés est de 100% dans toutes les chefferies du territoire de Mahagi y compris le centre justifiant ainsi l’absence de différence entre les chefferies quant à la qualification des maitres. Pour réduire les disparités retrouvées, l’étude propose, la création de 4197 écoles en territoire de Mahagi dont 250 écoles en Mahagi centre, 144 écoles à Alur djuganda, 1252 écoles à Anghal, 994 écoles à Djukot, 596 écoles à Mukambo, 409 écoles à Panduru, 98 écoles à Wagongo, 57 écoles à Walendu watsi et, 495 écoles à Warpalara.

The study aims to diagnose the school system of the territory of Mahagi in the Democratic Republic of Congo, in order to harmonize it. The assessment reveals that there are significant differences between the chiefdoms in terms of the gross rate of schooling (CV=0.73 > 0.30) this result, although not significant, shows imbalances in the efforts made throughout the territory of Mahagi in terms of schooling. There were significant differences at the level of the rate of occupation of the premises and supervision of the pupils (0.58>0.30) found and not significant at the level of the school size (0.26 between 0.15 and 0.30). However, the rate of qualified of teachers is 100% in all chiefdoms of Mahagi territory including the center. Hence, no difference between the chiefdoms as to the qualification of the professors is demonstrated. To reduce the found disparities, the study proposes the creation of 4197 schools in Mahagi territory, including 250 schools in Mahagi center, 144 schools in Alur djuganda, 1252 schools in Anghal, 994 schools in Djukot, 596 schools in Mukambo, 409 schools in Panduru, 98 schools in Wagongo, 57 schools in Walendu watsi and 495 schools in Warpalara.
The Loss of a Clan: Abandoning Ethos of the East African Revival by the Contemporary Kenyan Christian
Authors: Mwangi Perminus Mburu , Pam Gyang David , Nkansah-Obrempong James 
Published: November 2022

This study investigated two practises of the East African Revival (EAR) movement; the public testimony of one’s salvation and the public confession of all known sins. The study further sought to know the attitude of the contemporary Christian on the same. The study was qualitative in strategy with a phenomenological design. Criterion based purposive sampling was used to select the participants. The tools for gathering data were In-depth interviews, Focus Group Discussions, and Document Review. Thematic Coding Analysis was used to analyse the data. The EDNA model for practical theology was applied as the theological framework. Findings show that the EAR members held the public testimony and public confession of sin as foundational to their doctrine and practice. The two practices helped them to create a unique identity and cohesiveness, after separating from their familial clans at conversion, hence forming a new spiritual clan of their own. The contemporary Christian on the other hand finds these two tenets of the EAR,
intrusive and unacceptable. With no alternative ways of building cohesiveness and a unique identity, the younger believers are left without a clan hence becoming spiritual orphans. Traditional Anglicanism, with its focus on sacraments and liturgy, and African Traditional Religions are among the formations fighting to adopt these spiritual orphans. The study recommends that the church and society revisit these practices and apply them appropriately in the fight against corruption and tribalism, among other ills in Kenyan society.

Abstract
Background
PCOS is a common endocrine and metabolic disease related to infertility in women. Klotho, an anti-aging factor, was reported up-regulated in PCOS and related to excessive androgens. However, the role of Klotho in poor oocytes quality of PCOS who underwent IVF-ET has not been clarified.
Methods
72 PCOS and 70 healthy participants who underwent IVF-ET were enrolled and the follicular fluid was collected. Granulosa cells were collected from 15 patients. The level of Klotho in follicular fluid was tested by ELISA. The mRNA level of relative genes in granulosa cell were detected by qRT-PCR.
Results
the mRNA level of Klotho, Caspase-3, Caspase-9, IL-6 and TNF in PCOS group was significantly higher, especially in the group of PCOS with hyperandrogenism, while PCNA and GDF9 was down-regulated. Correlation analysis shown that level of Klotho in follicular fluid of PCOS group was negatively correlated with the number of mature oocytes. Similarly, we divided the PCOS group into two groups according to the median of Klotho level and found that the number of mature oocytes is significantly lower in the group of high level of Klotho. In addition, the Klotho level in follicular fluid was also positively correlated with serum testosterone, LH, LH/FSH, menstrual cycle and number of total antral follicles in the group of PCOS.
Conclusion
These data suggested that Klotho may act as a new biomarker evaluating the quality of oocytes in patients with PCOS, indicating the severity of PCOS and the outcome of IVF in PCOS patients.

Abstract
Smith-Magenis syndrome (SMS) is a neurodevelopmental disorder characterized by cognitive and behavioral symptoms, obesity, and sleep disturbance. There is no therapy to alleviate its symptoms or delay disease onset. SMS occurs due to haploinsufficiency of the retinoic acid-induced-1 (RAI1) gene caused by either chromosomal deletion (SMS-del) or RAI1 missense/nonsense mutation. The molecular mechanisms underlying SMS are not known. Here, we generated and characterized primary cells derived from four SMS patients, two carrying SMS-del and two carrying RAI1 point mutations, and four control subjects to investigate the pathogenetic processes underlying SMS. By combining transcriptomic and lipidomic analyses, we show altered expression of lipid and lysosomal genes, deregulation of lipid metabolism, accumulation of lipid droplets, and a block of autophagic flux. SMS cells show increased cell death associated with mitochondrial pathology and reactive oxygen species production. Treatment with N-acetylcysteine reduces cell death and lipid accumulation, suggesting a causative link between metabolic dyshomeostasis and cell viability. Our results highlight the pathological processes in human SMS cells involving lipid metabolism, autophagy defects and mitochondrial dysfunction and suggest new potential therapeutic targets for patient treatment.
