Analisis Koneksi Matematika Ditinjau dari Tipe Kepribadian Sanguinis, Koleris, Melankolis, dan Plegmatis
Authors: Anggreini Dewi , Eko Priyojadmiko  , Dwi Setiana
Published: July 2020

Mathematics is a subject that has the concept of interrelation between one material with another. Understanding the interrelated material required the existence of a basic ability that is the ability to connect mathematics. The obstacle experienced by students is that when given a problem and the solution is related to the previous material, students are unable to remember the material that is the key to solving the problem. The inability of students is due to lack of memory of previous material and students pay less attention when the teacher is explaining in class. Personality differences make students have different mathematical connection abilities. The purpose of this study is to describe the ability of students' mathematical connections in terms of sanguinis, koleris, melancholy, and plegmatic personality types. This type of research is a qualitative descriptive study in the form of case study research. Methods of data collection used personality type questionnaires, math connection test questions, and interviews. The results showed that the sanguinis and plegmatic personality types were able to meet all the connection indicators. Koleris personality type is able to fulfill 4 indicators. Melancholy personality types produce different connection capabilities, namely the ability of connections that meet 4 indicators and 1 indicator. This research can provide benefits for students to improve their mathematical connections and understand their personality types. Students who understand their personality types can minimize negative traits that inhibit mathematical connections.

BIM tool development enhancing collaborative scheduling for pre-construction
Authors: Tallgren Mikael Viklund , Roupé Mattias , Johansson Mikael , Bosch-Sijtsema Petra
Published: July 2020

Construction projects often suffer from backlashes in relation to poor plans and schedules. Especially pre-construction planning has been challenging due to a high complexity, an extensive amount of information, and a lack of site managers time to make the schedule. To solve these issues for pre-construction planning; new planning processes, methods and tools have been developed over the last decade. However, due to a disregard of the current planning processes these tools have been difficult to adopt in practice. In addition, these developed tools and methods are seldom developed from the user’s point of view. A promising development is the introduction of integrated planning as a concept in construction companies. It involves the use of BIM models in concert with a planning approach where the subcontractors engage in the planning. However, currently available tools are more geared towards experienced users such as expert planners and does not allow for a fully collaborative and integrated planning approach. While many current tools would tick many of the requirements identified, they still fail to address the base requirements from the collaborative work environment literature. This paper contributes with a user-centric design and development of a collaborative planning application showing the integration of the existing collaborative planning process. By adopting a socio-technical approach, the paper focuses on combining technology and processes supporting the users and their way of working in order to enable adoption of the solution. A design science research approach has been used to gather requirements and develop and evaluate the Visual Project Planner (VPP) application. The VPP application applies a collaborative, visual approach supporting interdisciplinary knowledge sharing between all parties involved where the subcontractors actively can contribute to schedule. The VPP application has potential to reduce time for pre-construction planning regardless of the planning approach used.

Artikel ini disusun berdasarkan hasil kajian dengan tujuan mengetahui dan memahami strategi menghadapi tantangan arus budaya global melalui pendidikan karakter berbasis budaya. Penelitian ini menggunakan metode kualitatif. Data diperoleh melalui observasi, wawancara, dokumentasi, dan studi pustaka dalam latar alamiah. Analisis data dilakukan melalui tiga kegiatan secara bersamaan yaitu reduksi data, penyajian data, dan simpulan atau verifikasi. Hasil kajian  menunjukkan bahwa dunia pendidikan dewasa ini tengah menghadapi tantangan arus budaya global, yakni proses dan sistem ekspansi ekonomi pasar bebas bersifat transnasional yang merambah ke dalam berbagai bidang kehidupan seperti politik, agama, sosial budaya, dan pendidikan. Pada era keterbukaan yang ditandai dinamika masyarakat lokal, nasional, dan global, berbagai dampak tidak dapat dihindari. Oleh karena itu, betapa penting suatu bangsa perlu memiliki karakter dan jati diri dalam menghadapi arus budaya global agar tetap berdiri kokoh di atas nilai-nilai luhur budaya bangsanya. Pendidikan karakter berbasis budaya dapat dijadikan strategi edukatif dan investasi simbolis disertai upaya-upaya untuk mewujudkan lingkungan sosial yang kondusif melalui tripusat pendidikan (keluarga, sekolah, dan masyarakat). Menghidupkan kembali nilai-nilai kebudayaan lokal dalam kemasan tertentu merupakan salah satu pendekatan kebudayaan untuk pemberdayaan. Dengan demikian, revitalisasi nilai-nilai budaya lokal dalam era globalisasi sangat penting. Hal itu perlu dilakukan mengingat perilaku budaya di kalangan anak-anak dan remaja mulai berubah seiring semakin kuatnya tekanan arus budaya global.
ZONE OF PROXIMAL DEVELOPMENT AND SOCIAL CONSTRUCTIVISM BASED EDUCATION ACCORDING TO LEV SEMYONOVICH VYGOTSKY
Authors: Payong Marselus Ruben
Published: July 2020

This article is a theoretical study of Vygotsky's idea of zone of proximal development. Its aimed at finding out of its relevance to contemporary educational practices that are increasingly complex. Through the description of the background of the emergence of this idea the author concludes that the idea of zone of proximal development is still relevant in modern education, especially to support the educational practices that are friendly toward student’s individual differences at school. Vygotsky's criticism of the practice of levering in schooling is a warning for teachers and education practicioners to consider learning interventions based on individual students' backgrounds especially their mental development differences so that education can be an effective medium to help children's growth and development optimally.

Authors: Widyawati Fransiska , Jenita Afriana
Published: July 2020

Artikel ini mendeskripsikan kegiatan pengabdian kepada masyarakat yang dilakukan oleh tim katekese Program Studi Pendidikan Teologi Universitas Katolik Indonesia Santu Paulus Ruteng. Katekese dilakukan sebagai pendidikan iman bagi umat pada Komunitas Basis Gerejawi dalam rangka Tahun Penggembalaan, Keuskupan Ruteng. PkM dilatarbelakangi oleh terbatasnya kegiatan pembinaan umat yang menjangkau seluruh umat di Paroki Santa Maria Assupta. Masalah ini terjadi karena minimnya tenaga pastoral dan keterbatasan sumber daya lainnya. Padahal, umat membutuhkan penyegaran iman, tambahan pengetahuan dan penguatan satu sama lain, khususnya dalam rangka mengisi Tahun Penggembalaan yang dicananangkan oleh Keuskupan Ruteng. Solusi yang ditawarkan oleh tim PkM adalah melaksanakan kegiatan katekese umat. Metode yang dipakai adalah metode “lonto leok” atau musyawarah tukar menukar pengalaman iman umat. Hasilnya umat memiliki peningkatan pengetahuan dan kesadaran mengenai Tuhan sebagai Gembala dan umat dapat saling menguatkan iman satu sama lain. Kesimpulannya PkM ini berhasil membantu mengatasi masalah umat setempat. Saran lanjutannya adalah agar kegiatan ini lebih sering dilakukan dan perlu adanya pembaharuan tema, pengetahuan dan metode demi memeroleh hasil yang lebih memuaskan.

Main vectors of develovpment of portrait sculpture in Lviv of 90s of the XX century in the context of the time. Changes, which occured in art, were identified; where new environment is being formed, in which portrait sculpture becomes an object of preservation and transmission of information. It’s proved that visualization of Ukrainian history is mainly due to developments in individual personification of events of prominent leaders of their time. The analysis of a number of sources related to the peculiarities of artistic and critical understanding of complex creative processes specific to Lviv sculpture of the period, was done. Portrait sculpture of Lviv of of 90s of the XX century is a complex of artistic phenomenon, which is rich in innovations and authentic artistic discoveries. Contemporary portrait sculpture is a history and culture of the people and their country, immortalized in stone and bronze.
Themes of heroism, patriotism, courage, creative work, love and family prevail in works of Lviv sculptors. Most of masters are turning to the historical past of their land. In the image-structural solutions portraits influenced the previous days, and plastic language primarily focused on traditional solutions. Portrait sculpture of Lviv artists resist to platitudes, engagement, technocracy, contrasting its naturalness, sensitivity and anxiety.
Gender theory, which asserts that the very fact the differences are not so important how important their socio-cultural assessment and interpretation, as well as construction of power systems based on these differences, dominated in portrait sculpture of contemporary Lviv artists.

Published: July 2020

The preconditions for the emergence of professional art education in the field of art glass in Lviv and Galicia are considered. The history of artistic glass and its influence on the development of the modern center in Lviv on the basis of the Lviv National Academy of Arts is analyzed. The history of the Department began in 1961 with an experiment, when at Lviv State Institute of Applied and Decorative Art (today Lviv National Academy of Arts) a small department of plastic and glass art was opened. Full formation of the unit took place in 1963–1964 and corresponded to the needs of provision with the specialists of experimental workshop of glass art of Lviv Experimental Ceramic and Sculpture Factory of those times. The curriculum of basic art disciplines is formed in accordance with the specificity of the material – glass art and is focused on consideration of the importance of imaginative or constructive thinking, according to selected specialized direction. For decades, the staff of the Glass Department keep contact with glass artists in the whole world, participates in organization of international symposiums and exhibitions, meetings with students, lectures, workshops with the participation of the most famous artists in the world. Since 1989, the teachers and staff of the Department have been actively participating in the organization of International Symposiums of Blown Glass that are the most long-lasting continuous forums of glass artists in the world nowadays. On the base of the Department, mini-symposiums for students took place, and in 2013 and 2016, a scientific and creative workshop (glass-melting furnace) became the main base for the work of famous glass artists from different countries of the world. Every three years the students have an opportunity to observe the work of the most world well-known glass artists from various countries, participate in workshops and lectures. The purpose of the article is to analyze the activities of the Department of Art Glass of the Lviv National Academy of Arts in the modern studio movement.
Pure $\mathcal{O}$-Sequences arising from $2$-Dimensional PS Ear-Decomposable Simplicial Complexes
Authors: Klee Steven , Nugent Brian
Published: July 2020

We show that the $h$-vector of a $2$-dimensional PS ear-decomposable simplicial complex is a pure $\mathcal{O}$-sequence. This provides a strengthening of Stanley's conjecture for matroid $h$-vectors in rank $3$.  Our approach modifies the approach of combinatorial shifting for arbitrary simplicial complexes to the setting of $2$-dimensional PS ear-decomposable complexes, which allows us to greedily construct pure multicomplex corresponding to each PS ear-decomposable complex.
Exploring Ex Ante Impacts and Social and Sportive Challenges of Hosting a Future New International Major Event: a Case Study of the World Roller Games in Barcelona
Authors: Saló Albert , López Laia
Published: July 2020

This analysis arises from the decision of the current local council of Barcelona regarding the post-ponement of the sporting mega-event "World Roller Games," due to a lack of a social and sportive implication in this event. This research tries to shed some light on the matter and give
evidence to the local council to become the world capital of skating. The research question is to analyze whether non-economic impacts could be relevant enough to organize a mega-event. The methodology is based on the perception and experience of spectators and participants on four main impacts
(social, economic, sports city image, and sports practice) using a survey from a National Roller Skating Championship in Spain, considering that this profile of respondents have a better knowledge of the current situation of this sport. There are positive expected future consequences of this
mega-event to be held in Barcelona in social and sportive terms. We can also conclude that the local council must still introduce some social and sportive policies in the city in order to improve the chances of success in social, sports practice, and sportive brand image development. It is
demonstrated that a mega-event should not be seen purely from a perspective of business generation, especially with minority sports like roller skating. There is a clear opportunity to develop social and sportive practice initiatives that can push social cohesion throughout the city thanks
to a mega-event such as this one.

Published: July 2020

It can be difficult for families with young children to navigate early childhood development supports. In particular, newcomer families often encounter additional barriers and require resources, programs, and services that are tailored to their unique assets, experiences, and needs. We conducted a scoping review of the literature published between 2000 and 2019 to explore what is known about newcomer families’ experiences with programs and services to support early childhood development in Canada. We searched 12 databases, screened 2390 articles, and included 34 articles for synthesis and analysis. Three common and connected themes were identified: 1) effective intercultural understanding, responsiveness, and communication are critical to ensuring full access to meaningful programs and services; 2) some newcomer families face systemic barriers exacerbated by their immigration status, and; 3) feelings and perceptions of families and service providers, as well as social supports, networks, and relationships influence how programs and services are accessed and experienced. Our review identifies the requirement for additional, participatory research that centres the voices and perspectives of newcomer children and their families and the need to expand that research to less populated and rural areas of the country to inform meaningful and culturally relevant policies, programs, and services for newcomer families to support their children’s well-being.

Simultaneous equation models describe a two-way flow of influence among variables. Simultaneous equation models using panel data, especially for fixed effect where there are spatial autoregressive and spatial errors with exact solutions, still require to be developed. In this paper, we develop the new models that it consist of spatial autoregressive and spatial errors. We call it as general spatial. This paper proposes feasible generalized least squares-three-stage least squares (FGLS-3SLS) to find all the estimators with exact solution and the numerical approximation estimators by concentrated log-likelihood formulation with method of forming sequence. All proposed estimators especially for closed-form estimators are proved to be consistent.

Analisis Jual Beli Manggis Sistem Borongan Sekali Musim Panen Dalam Perspektif Ekonomi Syari’ah Di Desa Wanasari Kecamatan Wanayasa Kabupaten Purwakarta
Authors: Sari Ayi Puspita , Saepudin Ahmad , Rohmat Siti
Published: July 2020

Tujuan dari penelitian ini yaitu untuk mengetahui sistem jual beli manggis secara borongan dengan akad perjanjian sekali musim panen manggis sudah sesuai berdasarkan akad Syari’ah atau masih terdapat unsur gharar dalam jual beli manggis ini.

Metode penelitian yang digunakan yaitu metode kualitatif dengan pendekatan studi kasus. Teknik pengumpulan data dilakukan secara triangulasi, yaitu mengumpulkan data tentang sistem jual beli manggis secara borongan melalui observasi, wawancara, dan dokumentasi kepada penjual dan pembeli manggis di tempat tersebut. Kemudian hasil dari penelitian akan dianalisis dengan cara mereduksi data, melakukan penyajian data dan menarik kesimpulan.

Hasil dari penelitian ini menunjukkan bahwa jual beli manggis secara borongan dengan menggunakan akad perjanjian sekali musim panen, dilakukan sebelum manggis layak dipanen dengan perjanjian penyerahan manggis diserahkan ketika musim panen tiba dengan syarat manggis berbuah lebat, sedangkan penyerahan uang dilakukan ketika terjadi awal akad. Apabila gagal panen buah lebat, maka uang pembeli tidak kembali, tetapi menunggu panen manggis lebat berikutnya. Jual beli manggis secara borongan dalam perspektif ekonomi Islam termasuk jual beli gharar atau jual beli ghaib karena tidak memenuhi syarat dan rukun jual beli, tidak ada kejelasan dalam penyerahan manggis.

Saran dari penulis, jual beli manggis lebih baik dilakukan ketika manggis sudah layak dipanen, guna menghindari gharar jual beli.

Authors: Sankhyayan Dr. Akhilesh , Sharma Dr. Anil , Jindal Vidushi , Thakur Dr. Malvika , Jindal Dr. Vikas , Singla Ayushi
Published: July 2020

Periodontitis has been a chronic inflammatory disease of the gingiva which eventually result in periodontal pocket formation with loss of the associated periodontal ligament and alveolar bone around teeth. Guided tissue regeneration (GTR), which is often a target for periodontal treatment, has the ability to promote periodontal regeneration. The development of the periodontal attachment is primarily concerned with tissue regeneration.Based on such concept, guided tissue regeneration is being utilized to varying degree of success to restore periodontal defects. In order to remove epithelium as well as gingival corium from the root and/or existing bone walls on the assumption that they interfere with regeneration, barrier techniques have been applied, using elements like expanded polytetrafluoroethylene, polyglactine, polylactic acid, calcium sulfate and collagen.

Published: July 2020

In South Sumatra Palembang, Light Rail Transit (LRT) which is one type of mass transportation has been built. LRT is a rail-based mass transportation facility with electric drive and can be used to carry passengers on a larger scale, but in the implementation of LRT operations require very large operational funds. The generated income from monthly sales ticket was unequal to the costs incurred for LRT operations. In this study, researchers used three options to obtain other income besides ticket sales, which are the income from ad space rent (stations, poles, railroad walls and LRT trains), trade stall rent, and ATM stall rent. The questionnaire survey was conducted on 400 sample companies in Palembang with the aim of getting the company's perception about the willingness to pay (WTP) for renting the advertising space and the ATM stall so that income generation can be predicted from the three options offered to the South Sumatra LRT operations. The analysis conducted in this study was a quantitative analysis with descriptive statistics. From the analysis it was found that the total income that would be received by the manager if all available locations had been occupied or rented were Rp. 10,080,715,996 once a year with the income proportion from advertising rent at 96.25%, income from trade stalls rent 2.08% and income from ATM stalls rent is 1.67%. It is expected that the existing income can help in funding operational in South Sumatra LRT.
Thermodynamic Study on Density and Viscosity of Binary Mixtures of Ethyl acetoacetate with (C4-C9) Aliphatic Ketones at (303.15 and 308.15) K
Authors: Kemeakegha Ayasen Jermaine , Jumbo Benjamin Amabebe
Published: July 2020

Investigation on Density (ρ) and viscosity (η) of various binary mixtures of ethylacetoacetate and straight chain aliphatic ketones (butan-2-one, pentan-2- one, hexan-2-one, heptan-2-one, octan-2-one and nonan2-one) have been carried out over the entire solvents composition range at temperatures of 303.15K and 308.15K. From the data obtained, the excess molar volumes (V E ), the excess viscosity (η E ) and excess Gibbs free energy of activation for viscous flow (ΔG*E) have been calculated from the experimental density and viscosity measurements at the working temperatures. Excess molar volumes, V E results are negative and positive over the entire range of mole fractions and become more positive as the chain length increases. The excess viscosities, η E were both positive and negative over the entire mole fraction range. While the observed excess Gibbs free energies of activation of viscous flow, ΔG*E data are positive throughout the entire mole fraction range of solvents composition at all investigated temperatures. These observed results of the excess functions have been interpreted in terms of possible molecular interactions in the binary mixtures.

Radio Echo in the Turbulent Corona and Simulations of Solar Drift-pair Radio Bursts
Authors: Kuznetsov Alexey A. , Chrysaphi Nicolina , Kontar Eduard P. , Motorina Galina
Published: July 2020

Drift-pair bursts are an unusual type of solar low-frequency radio emission, which appear in the dynamic spectra as two parallel drifting bright stripes separated in time. Recent imaging spectroscopy observations allowed for the quantitative characterization of the drifting pairs in terms of source size, position, and evolution. Here, the drift-pair parameters are qualitatively analyzed and compared with the newly developed Monte Carlo ray-tracing technique simulating radio-wave propagation in the inhomogeneous anisotropic turbulent solar corona. The results suggest that drift-pair bursts can be formed due to a combination of refraction and scattering processes, with the trailing component being the result of turbulent reflection (turbulent radio echo). The formation of drift-pair bursts requires an anisotropic scattering with the level of plasma density fluctuations comparable to that in type III bursts, but with a stronger anisotropy at the inner turbulence scale. The anisotropic radio-wave scattering model can quantitatively reproduce the key properties of drift-pair bursts: the apparent source size and its increase with time at a given frequency, the parallel motion of the source centroid positions, and the delay between the burst components. The trailing component is found to be virtually cospatial and following the main component. The simulations suggest that drift-pair bursts are likely to be observed closer to the disk center and below 100 MHz due to the effects of free–free absorption and scattering. The exciter of drift pairs is consistent with propagating packets of whistlers, allowing for a fascinating way to diagnose the plasma turbulence and the radio emission mechanism.
Hidden AGNs in Dwarf Galaxies Revealed by MaNGA: Light Echoes, Off-nuclear Wanderers, and a New Broad-line AGN
Authors: Mezcua Mar , Domínguez Sánchez Helena
Published: July 2020

Active galactic nuclei (AGNs) in dwarf galaxies could host the relics of those early universe seed black holes that did not grow into supermassive black holes. Using MaNGA integral field unit (IFU) spectroscopy we have found a sample of 37 dwarf galaxies that show AGN ionization signatures in spatially resolved emission line diagnostic diagrams. The AGN signatures are largely missed by integrated emission line diagnostics for 23 of them. The bolometric luminosity of these 23 new AGN candidates is ≲1040 erg s−1, fainter than that of single-fiber SDSS AGNs, X-ray AGNs, and radio AGNs in dwarf galaxies, which supports IFU spectroscopy as a powerful tool for identifying hidden and faint AGNs in dwarf galaxies. The AGN emission is in most cases offset from the optical center of the dwarf galaxy and shows a symmetric morphology, which indicates that either the AGNs are off-nuclear, that the central emission of the galaxy is dominated by star formation, or that the AGNs are turned off and we are observing a past ionization burst. One of the new AGNs shows a broad Hα emission line component, from which we derive a black hole mass in the realm of intermediate-mass black holes. This constitutes the first hidden type 1 AGN discovered in a dwarf galaxy based on IFU spectroscopy. The finding of this sample of hidden and faint AGNs has important implications for population studies of AGNs in dwarf galaxies and for seed black hole formation models.
Detection of Fe i Emission in the Dayside Spectrum of WASP-33b*

Published: July 2020

We analyze the high-resolution emission spectrum of WASP-33b taken using the High Dispersion Spectrograph (R ≈ 165,000) on the 8.2 m Subaru telescope. The data cover λ ≈ 6170–8817 Å, divided over 30 spectral orders. The telluric and stellar lines are removed using a de-trending algorithm, SysRem, before cross-correlating with planetary spectral templates. We calculate the templates assuming a 1D plane-parallel hydrostatic atmosphere including continuum opacity of bound–free H− and Rayleigh scattering by H2 with a range of constant abundances of Fe i. Using a likelihood-mapping analysis, we detect an Fe i emission signature at 6.4σ located at

of 226.0

km s−1 and v
sys of −3.2

km s−1—consistent with the planet’s expected velocity in the literature. We also confirm the existence of a thermal inversion in the dayside of the planet, which is very likely to be caused by the presence of Fe i and previously detected TiO in the atmosphere. This makes WASP-33b one of the prime targets to study the relative contributions of both species to the energy budget of an ultra-hot Jupiter.

Background/aim: The aim of the study was to evaluate the protective effect of Botulinum A toxin injection against ischemia-reperfusion injury.Materials and methods: Thirty-two Sprague-Dawley rats were divided into: control, ischemia-reperfusion, ischemic preconditioning, and botulinum groups. In all groups the musculocutaneous pedicle flap was occluded for 4 h, and then reperfused to induce ischemia-reperfusion injury. Serum and tissue myeloperoxidase (MPO) and nitric oxide (NO) levels were measured at 24 h and at 10 days.Results: Tissue MPO levels did not differ significantly between the ischemic preconditioning and botulinum groups at 24 h but was significantly lower in the botulinum group at 10 days. Tissue NO levels were significantly higher in the ischemic preconditioning group compared to the botulinum group at 24 h and at 10 days. Serum MPO showed no significant difference between these two groups at 24 h but was significantly lower in the ischemic preconditioning group compared to the botulinum group at 10 days. Serum NO levels were not significantly different at 24 h but significantly higher in the botulinum group at 10 days.Conclusion: Findings show that botulinum has a protective effect against the ischemia-reperfusion injury via increased NO and decreased MPO levels in tissue. Based on tissue NO levels, ischemic preconditioning was significantly higher than botulinum.

Published: July 2020

Liver surgery is one of the most complex surgical interventions with high risk and potential for complications. Posthepatectomy liver failure (PHLF) is a serious complication of liver surgery that occurs in about 10% of patients undergoing major liver surgery. It is the main source of morbidity and mortality. Appropriate surgical techniques and intensive care management are important in preventing PHLF. Early start of the liver support systems is very important for the PHLF patient to recover, survive, or be ready for a liver transplant.

Background/aim: Nailfold video capillaroscopy is considered as a reliable method for evaluating peripheral microangiopathy in rheumatologic diseases. In this study, we aimed to demonstrate the utility of handheld dermatoscopy as an easy-to-use nailfold capillaroscopic instrument in patients with rheumatoid arthritis.Materials and methods: This cross-sectional study included patients with rheumatoid arthritis and healthy subjects. A handheld dermatoscopic examination of proximal nail fold was performed in each subject. The possible correlation of capillaroscopic findings with disease activity was evaluated using the disease activity score 28 (DAS28).Results: A total of 59 patients with rheumatoid arthritis and 60 healthy subjects were enrolled in the study. The presence of capillaryenlargement, avascular areas, capillary deformities, and capillary vascular anomalies in the group of patients showed a statistically significant difference when compared with the healthy subjects. No correlation was found between the nail fold capillaroscopic findings and DAS28 score.Conclusion: Hand-held dermatoscopy seems to be a useful technique in the evaluation of nail fold capillary changes. We suggest that in patients with rheumatoid arthritis, when capillaroscopic examination is needed, it can be evaluated using handheld dermatoscopy. Selected patients who showed findings using this method can be further examined with classical capillaroscopy to obtain more quantitative data.
Accéder à l’automobile dans les villes d’Afrique subsaharienne : usages et usagers dakarois
Authors: Diaz Olvera Lourdes , Plat Didier , Pochet Pascal
Published: July 2020

L’Afrique subsaharienne, qui compte pour 13 % de la population mondiale en 2015, ne représente à cette date que 2 % du parc automobile et l’importance des modes motorisés individuels reste très faible dans nombre de villes. Ces dernières années, la croissance des parcs des pays africains est cependant bien réelle, avec une concentration dans les capitales et grandes villes. Mais leur taille actuelle suggère que la motorisation et l’usage de la voiture représentent aujourd’hui un rêve inaccessible pour le plus grand nombre. Qu’en est-il vraiment ? Nous analysons ici la place de la voiture à travers ses usagers et ses usages à Dakar (Sénégal) : qui la possède, qui peut en disposer, pour quels usages et pour quelles pratiques de mobilité, avec quelles évolutions ? Nous mobilisons une catégorisation qui distingue trois types d’utilisateurs, selon que leur ménage possède ou non une voiture et, dans l’affirmative, selon leur capacité à y accéder en permanence. Des analyses secondaires de deux enquêtes ménages mobilité réalisées à Dakar en 2000 et 2015 et d’entretiens semi-directifs auprès des citadins menés en 2015 montrent que la concentration de l’équipement en voiture s’est renforcée en quinze ans, les plus riches possédant proportionnellement plus de véhicules, le poids de Dakar s’étant accentué par rapport à celui des autres départements de la métropole. Les profils des usagers et leurs usages révèlent qu’en dépit de sa rareté et des coûts d’utilisation élevés, la voiture est diffusée au-delà du cercle restreint des citadins pouvant en disposer en permanence. Mais les trois types d’utilisateurs se retrouvent dans des situations inégales vis-à-vis de l’automobile. La mise en regard de 2000 et 2015 suggère des évolutions à venir, portées par des effets de génération et par les dynamiques spatiales.
La participación de las mujeres empresarias en redes de colaboración
Authors: Fischer de la Vega Laura Estela , Saavedra García María Luisa , Camarena Adame María Elena
Published: July 2020

L’objectif de cet article est de déterminer comment les femmes d’affaires participent aux réseaux collaboratifs, et si cette participation est liée aux caractéristiques de l’entreprise et de la femme d’affaires. Un questionnaire a été appliqué par le biais d’un travail sur le terrain à un échantillon de 272 femmes d’affaires bénévoles de Mexico. Les principales conclusions sont les suivantes: les femmes d’affaires ne connaissent pas et ne participent donc pas à des réseaux collaboratifs qui pourraient leur être utiles pour la croissance et la consolidation de leur entreprise, ni ne participent à des programmes publics qui pourraient leur fournir des conseils et un soutien financier. Enfin, nous ignorons qui sont leurs clients et leurs concurrents. L’utilisation des réseaux est liée aux caractéristiques de l’entreprise et de la femme d’affaires.

Factors Predicting the Onset of Amnestic Mild Cognitive Impairment or Alzheimer's Dementia in Persons With Subjective Cognitive Decline
Authors: Ahn Sangwoo , Mathiason Michelle A. , Salisbury Dereck , Yu Fang
Published: July 2020

The objective of the current retrospective cohort study was to identify vascular and/or neuropsychiatric risk factors predicting clinical progression in persons with subjective cognitive decline (SCD). Information on 1,525 persons with SCD (mean age = 73.8 [
SD
= 8.1] years) was obtained from the National Alzheimer's Coordinating Center. Clinical progression occurred from SCD to either amnestic mild cognitive impairment or Alzheimer's dementia over an average of 4.7 (
SD
= 2.9) years. Stepwise Cox regression was used. Compared to obesity (hazard ratio [HR] = 0.59) in the univariate unadjusted model, obesity (HR = 0.64), current smoking (HR = 2.02), and depressive symptoms (HR = 1.35) were significant after adjusting for covariates in the univariate model. In the multivariate adjusted model, obesity (HR = 0.64), current smoking (HR = 2.04), and depressive symptoms (HR = 1.36) remained significant predictors. Interventions should be designed to minimize transition by managing smoking and depressive symptoms. Further research is required for associations between obesity and clinical progression to test the hypothesis of obesity paradox. [

Dementia-Focused Person-Directed Care Training With Direct Care Workers in Nursing Homes: Effect on Symptom Reduction
Authors: Reinhardt Joann P. , Burack Orah R. , Cimarolli Verena R. , Weiner Audrey S.
Published: July 2020

The majority of older adult nursing home residents have dementia and are at risk of not having their care needs met, largely due to communication deficits. Promoting comfort and minimizing distress for these residents is important. Direct care workers (DCW) and clinical staff completed a 6-day training on a person-directed care (PDC) model—a model guided by the needs of the individual that focuses on empowering DCW to understand and support resident preferences and remaining abilities supported by relationship development and consistent staffing. A retrospective comparison was conducted of residents in two PDC communities with matched residents (
n
= 72) and three traditional communities (
n
= 72) on functional and clinical outcomes over a 6-month period. A two-way analysis of variance showed a significant interaction between group and time, where only those in the PDC group had a decreased number of clinical symptoms (e.g., pain, depression, agitation) over time. This study found support for the benefit of PDC on clinical outcomes of interest over time. PDC training for DCW and clinical staff promotes quality care and the reduction of clinical symptoms, leading to improved quality of life. [

We Are the One: Subcultural Politics and Leisure in Early San Francisco Punk
Authors: Foley Michael Stewart
Published: July 2020

This essay examines the ways in which politics and leisure were entangled in early San Francisco punk. Although San Francisco is perhaps uniquely associated with the counterculture of the 1960s, the city was, by the late 1970s, also home to a punk scene largely defined by its fierce engagement with political issues. At the same time, punks experienced this scene — which existed at a time of sustained national, state, and local crisis — as deliriously fun. Their idea of fun was vastly different than mainstream ideas of American leisure, but there is no denying that punk, like most subcultures, was experienced at least in part as a leisure activity. I argue that punks acted deliberately to not only intertwine fun and politics, but to make fun and play vehicles for political struggle, if not revolution. At least in this one major American city, punk was equal parts political engagement and diversion, equally confrontational and escapist. More importantly, the leisure and fun elements contributed to the building of a prefigurative community as a micro-model of what punks hoped could be achieved on a larger scale. In that way, fun and politics contributed to a fundamentally utopian vision in a subculture marked not by nihilism — as punk is so often cast — but by possibility.
(Re)inventing a People on the Sea: Instances of Creolization in Amitav Ghosh’s Sea of Poppies
Authors: Mulla Ahmed
Published: July 2020

While the East India Company made huge profits from the opium trade between its Indian dominion and China in the 1830s, many people in the colony, Indians and Europeans alike, felt their future was hopeless. Ruined by the compulsory cultivation of opium to the detriment of traditional agriculture that guaranteed self-reliance, or condemned by social prejudice, men and women were left with no other option than to seek a future elsewhere. Forced to share a confined place during a lengthy boat trip to an unknown destination in the Indian Ocean, people of opposed social and cultural backgrounds had to adjust to the unwritten laws of a community formed by chance. The characters of Amitav Ghosh's historical novel, Sea of Poppies, belong to the early waves of indentured workers that traveled throughout the Indian Ocean in the hope of a less arduous future. Notwithstanding their individual fate, Ghosh’s narrative shows that the ship constitutes a transitory “society” where each one has to re-negotiate his or her relationship to diversity.
