Dieudonné : antisémitisme, panique morale et communauté déviante
Authors: Proust Serge , Michalon Jérôme , Maurin Marine , Noûs Camille
Published: November 2020

À partir d’une enquête sur plusieurs spectacles de Dieudonné, cet article analyse l’articulation entre l’antisémitisme et une critique réactionnaire des sociétés occidentales centrée sur la disparition des normes hétérosexuelles. Nous montrons que l’adhésion à cette articulation est d’autant plus forte qu’elle s’exprime dans l’espace-temps des représentations publiques, où Dieudonné met en scène sa stigmatisation tout autant qu’il la transcende. Dans l’interaction avec un public se sentant également stigmatisé, se constitue ainsi une « communauté déviante », à travers la transgression d’« interdits » perçus comme participant de l’effondrement moral des sociétés occidentales.
Le (double) passeport des élites africaines. Être et rester cosmopolite au Mali grâce à l’acquisition d’une seconde citoyenneté
Authors: Mary Kevin
Published: November 2020

Cet article interroge les différentes significations que peut prendre l’acquisition d’une seconde citoyenneté et donc d’un second passeport chez les élites africaines. Basé sur un travail de terrain au Mali, l’article passe en revue les multiples avantages relatifs à la possession d’un tel document d’identification : facilitation de circulation mais aussi outil de distinction et source d’une certaine forme de sécurité, pour soi et pour sa famille. L’article plaide ainsi pour la prise en compte des citoyennetés dans la définition des classes sociales.
Du réfugié yéménite à l’entrepreneur. Quand l’exil de guerre devient opportunité économique à Djibouti
Authors: Lauret Alexandre
Published: November 2020

En s’appuyant sur des données empiriques récoltées auprès des réfugiés yéménites à Djibouti, cet article traite de l’articulation entre réfugiés, opportunité économique et formation d’une classe sociale en exil. La guerre au Yémen a entraîné l’exode d’une partie de la population yéménite vers les États voisins. Sur la rive africaine, Djibouti accueille une partie de ces réfugiés. Certains sont envoyés au camp de réfugiés de Markazi à Obock et d’autres intègrent les réseaux « arabes » de Djibouti présents depuis la colonisation française. Ces populations commencent alors à travailler au sein de la diaspora. Au Yémen, la guerre qui se prolonge paralyse l’économie du pays. Quelques années après le premier exode, de nouveaux réfugiés yéménites arrivent à Djibouti. Ils sont en contact avec les premiers réfugiés urbains : ce sont des amis ou des membres de la famille. Ils représentent une nouvelle classe de réfugiés en quête de travail localement, tout en restant en lien avec leurs familles au Yémen.
Le corps et l’esprit dans les mouvements spirituels californiens et Internet aux États-Unis (années 1960 et années 2010)
Authors: Kogiso Kohei , Miura Atsushi
Published: November 2020

La culture spirituelle californienne des années 1960 a à la fois popularisé la pratique corporelle du yoga et stimulé le développement de la technologie informatique et celui d’Internet. Cet article cherche à comprendre la situation actuelle de la pratique spirituelle et de la méditation à travers la comparaison de ces mouvements californiens entre les deux époques. Dans les années 1960, les jeunes se sentant menacés par la culture industrielle et urbaine du capitalisme cherchaient à reconstruire l’unité du corps et de la conscience afin de se libérer de ce monde à travers l’exploration du spiritualisme asiatique, comme le montrent les cas de l’Institut Esalen et du Whole Earth Catalog. Ces jeunes explorèrent la méditation et développèrent la nouvelle technologie numérique comme moyen de créer des communautés virtuelles. Alors que, dans les années 2010, la méditation ainsi qu’Internet sont largement diffusés, comme le montre Search Inside Yourself, les jeunes négligent pourtant le corps et perdent l’intérêt pour l’autre monde ; ils cherchent simplement à contrôler leurs corps pour s’adapter au monde actuel.

Business Intelligence-Driven Supply Chain Optimization in Emerging Markets
Authors: Asiegbu Gregory Uche
Published: November 2020

Organizations produce churns of complex, opaque, and meaningless data. Business intelligence systems (BIS) help organizations efficiently use their data in promptly making quality decisions. The limitations of conventional BIS in processing the volume, variety, and veracity of data available in organizations and the operational cost of maintaining its infrastructure gave rise to implementing Cloud BIS, which describes the deployment of BIS over the cloud platform enabling resource elasticity, moderate usage cost, unlimited resources, and offering greater value at a reduced cost than the traditional BIS. BIS aids a productive supply chain and given the complexities of Africa's supply chain and high volatility of its business environment, BIS over the cloud platform would be a great enabler. This chapter aims to provide an understanding of how BIS will transform supply chain management in Africa's emerging market.

The Role of Social Media in Event Marketing
Authors: Serin Karacaer Serap
Published: November 2020

Activities, which include events that are not all intangible, include large-scale service components, and hence, their marketing includes service marketing. From this point of view, it is possible to state that it is very difficult to market activities that the participants cannot take home and consume physically. In this context, it is very important that the event marketing activities convey the feeling to the target audience that they will have fun and be entertained. Therefore, social media is one of the most important tools used in the effective transfer of the organization to the target audience within the scope of event marketing activities. As the most effective current communication and interaction tool, social media has become the most important tool for event marketers who are trying to appeal to large audiences and promote a certain destination, product, or service.
Co-Production and Educational Change
Authors: Jensen Hanne , Morris Aaron Lee
Published: November 2020

For programs promoting responsive practices in education, and in particular learning through play, equating ‘scalable' with ‘formulaic, easily replicable trainings' carries the risk of achieving superficial shifts in participants' attitudes and practices, rather than sustained change. Part of the reason is the fundamental mismatch between the practices in focus (i.e., responsive practices) and the training approach itself (i.e., prescriptive). As an alternative, this chapter explores the merits of co-production for meaningfully and sustainably equipping educators at scale. From a microlevel view of co-productive processes in education settings, the authors illustrate two distinct potentials, which combine to form a flexible program strategy: first, co-production as a sense-making process to contextualize programs, and secondly, co-production as a catalyst for capacity building. The chapter concludes with future research needed to better understand flexible program strategies based on co-production, and the change journeys of educator learners participating in such programs.
Exploring the Effectiveness of Storytelling in Advertising Through Eye-Tracking
Authors: Casado-Aranda Luis-Alberto , Sánchez-Fernández Juan , Paço Arminda
Published: November 2020

From a marketing perspective, storytelling involves creating, through advertising and communication strategies, an image of the company, brand, and products that makes it different from the competition. Advertising literature has shown that good stories have a way of inspiring, entertaining, explaining, and convincing, and can engage the emotional, attentional, and cognitive schemes of the customers. This is the first research that defines and makes an overview of the evolution of eye-tracking systems in the field of advertising which employs storytelling techniques. Particularly, the current chapter identifies the evolution of topics and relations between them, within the field of advertising research. The current study, therefore, advances an agenda for future research and constitutes a starting point for academics and professionals working in the field of advertising who intend to resort to eye-tracking techniques.
No More Drama
Authors: Rojas-Lamorena Álvaro J. , del Barrio-García Salvador , Alcántara-Pilar Juan Miguel
Published: November 2020

The undeniable development of the television series sector in recent years has resulted in viewers having access to a large amount of television content, thanks largely to the development of technologies such as the internet and the emergence of video on demand. Given the scarcity of academic works that categorise these television contents, this chapter comes to conceptually delimit the television drama genre, as well as its different sub-genres. With this, the authors seek to centralise in a single academic work the main characteristics of each dramatic sub-genre that causes a series to be ascribed to a certain category, serving as a guide for potential academic works related to this growing sector.
Unmasking Gender-Based Violence in Venezuelan Media
Authors: Garrido Mariateresa
Published: November 2020

The Venezuelan government has been instrumental to implement different types of gender-based violence and discrimination. Reports demonstrate that women have been killed, that their economic power decreased, and that they experienced problems related to access to education, health services, jobs, etc. This reality affects all women; however, there is not updated and systematized information about the problems faced by Venezuelan women journalists. This chapter uses Mohanty's theory and Hernandez's approach to illustrate the situation. It begins with an overview of the Venezuelan context, highlighting cases of gender-based violence and discrimination experienced by women. It also considers cases of economic exploitation, exclusion, disempowerment, cultural imperialism, and direct violence between 2018 and 2019. The chapter demonstrates the deteriorating situation and reveals patterns of oppression experienced by female journalists in Venezuela.

Authors: Bampasidis Georgios , Galani Apostolia , Koutromanos George
Published: November 2020

The aim of this study was to explore the development of pre-service primary school teachers' STEM skills with Raspberry Pi activities. Data were collected from 16 pre-service teachers through semi-constructed interviews, reports, and a questionnaire. The results of the qualitative analysis showed that the participants developed the STEM skills mentioned in the literature such as confidence, computing, problem-solving, creativity, technological skills, and enhanced the learning potential of robotics. Moreover, the ready-to-use Python codes on Raspberry Pi platform could be an effective strategy for pre-service teachers with lack of programming to provide solutions on real-world problems. In addition, the participants successfully connected the Raspberry Pi, sensor kits, and Python scripts with real-world problems. This equipment motivated them to transpose a real-world problem to school knowledge. According to the results the combination of Raspberry Pi, sensors, and Python helped the participants upskill in computing.

Authors: Chien Ting Fang Claire , Fahey Patrick G.
Published: November 2020

In this chapter, the authors demonstrate how a university Art Education program assists the university art museum and trains students to lead tours for BRAINY (BRinging Arts INtegration to Youth), the museum's educational program for Title I schools. The authors present how they guide student educators to develop tours for BRAINY by applying different interpretive strategies. The impacts that BRAINY creates for the visiting students and local communities include 1) the enhancement of civic engagement for young citizens, 2) high-quality art experiences for Title I schools, 3) the extended community program—Family Day. The impacts on student art educators are 1) knowing how to teach art in different learning contexts that are outside of the classroom, 2) applying the questioning strategies to their classroom teaching for probing art dialogues with students, 3) learning to be prepared but also flexible for unexpected situations. This chapter provides a practical and positive example to address a wonderful collaboration between an art museum, community members, and higher education.

Authors: Dessie Dereje Bekele , Nigussie Abay Sahle
Published: November 2020

The postnatal period is defined as the first six weeks after birth; it is critical to the health and survival. The study was conducted to determine the key factors of maternal postnatal care using Bayesian multilevel analysis using 7,192 mothers aged between 15-49 of EDHS 2016 data. Descriptive statistics revealed that 675 (9.4%) women received postnatal care. The Bayesian multilevel model used to analyze postnatal care utilization of woman. The predictor variables like mother's age, region, place of residence, media exposure, religion, wealth index, parents' education level, and mothers' occupation were found to be significant determinants of variation in women postnatal care utilization in Ethiopia. The Bayesian multilevel logistic regression analysis also estimates the variance of random effect at the regional level. Thus, the value of var (u0j) = δ2= 0.127 is significant at the 5% level of significance. In order to convey policies, it is important not only to comprehend the effect of reforms on the issues, but also on the how it diverges with demographic and economic characteristics.

Authors: Alsultanny Yas A. , Alharbi Eiman
Published: November 2020

The renewable energy sources were considered as a potentially promising and far less harmful alternative to traditional methods of electrical production. The main aim of this paper is to evaluate the seasonal weather influence on the electrical power generation from solar cells. Experimental and quantitative methodologies were used to analysis the data were collected from two sources the primary data were collected from PhotoVoltaic (PV) system of capacity 1200W for one year. The second source of data were collected from the Kuwait Directorate General of Civil Aviation. The key findings of the results showed that the daily sunlight hours are considered an important factor for electrical power generation; the temperature had reverse impact when it raised to more than 30oC, and the relative humidity had reverse impact when it raised to more than 49%. The CO2 avoided by this system was 1.325tonnes per year. The recommendation of this study is to depend on PV cells to reduce dependence on fossil fuels.

Authors: Nour Amro A. , Bostani Ali , Awadhwal Girish
Published: November 2020

A tapered fork-shaped antenna having small ground for ultra-wide band (UWB) antenna is proposed in this paper. Finite element method has been successfully employed to simulate and optimize the feed line, ground, and tapered fork-shaped diameter to enhance the performance of the antenna in terms of bandwidth obviously for the ultra-wideband purposes. An acceptable impedance matching performance has been achieved, which is a band wider than the UWB band that is defined by the Federal Communications Commission (FCC). In this paper, the detailed design parameters including the key elements in bandwidth enhancement is presented. The results of the finite element simulations have been presented as well indicating the return loss and radiation pattern of the proposed antenna.
Video Summarization Based on Multimodal Features
Authors: Zhang Yu , Liu Ju , Liu Xiaoxi , Gao Xuesong
Published: November 2020

In this manuscript, the authors present a keyshots-based supervised video summarization method, where feature fusion and LSTM networks are used for summarization. The framework can be divided into three folds: 1) The authors formulate video summarization as a sequence to sequence problem, which should predict the importance score of video content based on video feature sequence. 2) By simultaneously considering visual features and textual features, the authors present the deep fusion multimodal features and summarize videos based on recurrent encoder-decoder architecture with bi-directional LSTM. 3) Most importantly, in order to train the supervised video summarization framework, the authors adopt the number of users who decided to select current video clip in their final video summary as the importance scores and ground truth. Comparisons are performed with the state-of-the-art methods and different variants of FLSum and T-FLSum. The results of F-score and rank correlation coefficients on TVSum and SumMe shows the outstanding performance of the method proposed in this manuscript.
High-Fidelity AeroAcoustic Optimization Tool for Flexible Rotors
Authors: Wang Li , Diskin Boris , Lopes Leonard  V. , Nielsen Eric  J. , Lee-Rausch Elizabeth , Biedron Robert  T.
Published: November 2020

A high-fidelity multidisciplinary analysis and gradient-based optimization tool for rotorcraft aero-acoustics is presented. Tightly coupled discipline models include physics-based computational fluid dynamics, rotorcraft comprehensive analysis, and noise prediction and propagation. A discretely consistent adjoint methodology accounts for sensitivities of unsteady flows and unstructured, dynamically deforming, overset grids. The sensitivities of structural responses to blade aerodynamic loads are computed using a complex-variable approach. Sensitivities of acoustic metrics are computed by chain-rule differentiation. Interfaces are developed for interactions between the discipline models for rotorcraft aeroacoustic analysis and the integrated sensitivity analysis. The multidisciplinary sensitivity analysis is verified through a complex-variable approach. To verify functionality of the multidisciplinary analysis and optimization tool, an optimization problem for a 40% Mach-scaled HART-II rotor-and-fuselage configuration is crafted with the objective of reducing thickness noise subject to aerodynamic and geometric constraints. The optimized configuration achieves a noticeable noise reduction, satisfies all required constraints, and produces thinner blades as expected. Computational cost of the optimization cycle is assessed in a high-performance computing environment and found to be acceptable for design of rotorcraft in general level-flight conditions.
Orthostatic hypotension in older adults: the role of medications
Authors: Rivasi Giulia , Ungar Andrea
Published: November 2020

Orthostatic hypotension (OH) is defined as an abnormal blood pressure reduction when standing and is frequently diagnosed in older adults. Pharmacological therapy is one of the main causes of orthostatic blood pressure impairment, leading to iatrogenic OH. Indeed, several medications may induce hypotensive effects and influence the blood pressure response to orthostatism. Hypotensive medications may also overlap with other determinants of OH, thus increasing the burden of symptoms and the risk of complications. Potentially hypotensive medications include both cardiovascular and psychoactive drugs, which are frequently prescribed in older patients. According to the available evidence, the antihypertensive treatment “per se” does not seem to predispose to OH, even if a higher risk is associated with polypharmacy and drug classes such as with diuretics and vasodilators. As concerns psychoactive medications, OH is a well-known adverse effect of tricyclic antidepressants, trazodone and antipsychotics. The knowledge of hemodynamic consequences of drug therapy may be helpful to improve OH treatment. A medication review is advisable in all patients presenting with OH, particularly at advanced age, aiming at optimizing medical treatment with a view to minimize the risk of iatrogenic OH.
Antithrombotic therapy in acute coronary syndrome: undertreatment of elderly?
Authors: Muraca Iacopo , Ciatti Francesca , Migliorini Angela , Marchionni Niccolò , Valenti Renato
Published: November 2020

The appropriate use of dual antiplatelet therapy (DAPT) in elderly patients with acute coronary syndrome (ACS) is largely debated. Due to the "demographic transition" in western countries, the elderly represent a growing percentage of patients admitted to hospitals for ACS, and among this high risk setting population most of early and late adverse outcomes occur. The presence of several concomitant “comorbidities” complicate the management strategy of both medical or invasive treatment and the clinical decision making process is challenging. Moreover, elderly people are constantly underrepresented in clinical trials and studies. As a result, there is no specific evidence about the optimal antithrombotic therapy in elderly and no specific recommendations are mentioned in the current ACS guidelines. Currently, the best practice for old people is still rudimentary and principally extrapolated from general cardiovascular guidelines. The management of elderly patients should be based on the evaluation of ischemic and hemorrhagic risk, life expectancy, comorbidities and parameters that are not included in the scores recommended by the current guidelines such as frailty and disability. In the era of “precision medicine”, the evaluation of bleeding and ischaemic risk in elderly patients must be a dynamic process because of the risk changing over time. A“tailored therapy by individualized medicine” is the key of management strategy.
Phacoemulsification vs manual small incision cataract surgery in eyes affected by pseudo exfoliation syndrome with grade II and III cataracts
Authors: Subudhi Praveen , Khan Zahiruddin , Subudhi B. Nageswar Rao , Sitaram Silla , Patro Sweta
Published: November 2020

PURPOSE:

To compare the postoperative alteration of central corneal thickness (CCT) and visual outcomes between phacoemulsification (group A) and manual small incision cataract surgery (MSICS) (group B) in grade II and III nuclear cataracts (NS II and III) with pseudoexfoliation syndrome (PXF).

METHODS:

It is a double masked prospective randomised interventional study. A total of 60 eyes of 60 patients were assigned randomly to either the phacoemulsification (group A) or MSICS (group B) groups. All eyes had nuclear sclerosis grade II and III (LOCS II grading system) with pseudoexfoliation material either over the pupillary margin, anterior lens capsule, or both. All surgeries were done by a single surgeon. Postoperative evaluation was scheduled on the 1st, 30th, 90th, and 180th-day. Statistical analyses were done using appropriate methods. Outcome of the study were measured with changes in central corneal thickness (CCT), Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA) and the spherical equivalent in the operated eye up to 6 months post surgery.

RESULTS:

The mean preoperative CCT showed no difference between the groups (0.9659). The mean rise in CCT on the 1st postoperative day (POD) showed a significant difference between the groups {24.65 (SD 9.32) [group A (Phacoemulsification)] and 33.34 (SD11.68) [group B (MSICS)] (P < 0.0023)}. At the 1st, 3rd, and 6th month postoperative visits, there was no significant difference. The mean uncorrected distance visual acuity (UDVA) on the 1st POD was 0.189 (SD 0.118) in Group A and 0.302 (SD 0.121) in group B (P < 0.0005) which was significantly better with the phacoemulsification procedure. At the 1st month it was 0.039 (SD 0.084) in group A and 0.148 (SD 0.089) in group B (P < 0.004), which remained almost stable after that. The mean corrected distance visual acuity (CDVA) at the 1st, 3rd, and 6th-month postoperative visits showed no significant difference (P 0.8). The mean spherical equivalent was 0.29 in group A and 0.8 in group B.

CONCLUSION:

In moderately hard nuclear cataracts with PXF, phacoemulsification provides better unaided visual outcomes with less endothelial dysfunction than MSICS in the immediate and subsequent postoperative period.
Incidence and quantification of corneal haze by Pentacam Scheimpflug densitometry following photorefractive keratectomy for myopia in virgin and post corneal transplant eyes with dark irides
Authors: Khattak Ashbala , An-Nakhli Fouad
Published: November 2020

PURPOSE:

To assess the incidence and quantification of corneal haze after myopic photorefractive keratectomy in virgin and post corneal transplant eyes with dark irides.

METHODS:

In this retrospective study at the tertiary eye hospital, the corneal haze was evaluated by slit-lamp and quantified by Pentacam Scheimpflug densitometry after myopic photorefractive keratectomy with mitomycin C in virgin eyes (group I) and post corneal transplant eyes (group II) with dark irides over 12 months.

RESULTS:

Group I compromised 126eyes from 77patients (35males and 42females) aged 31.31 years (24.11–36.18 years), and group II compromised 44eyes from 33patients (18males and 15females) aged of 32.25 years (26.15–36.66 years). The incidence of corneal haze was 9.5% (95%CI: 5.0%–16%) and 6.8% (95%CI: 1.4–18.7%) in group I and II respectively (P = 0.587). The corneal densitometry was 22.69 ± 8.28GSU preoperatively and 17.98 ± 3.13GSU at 12 months postoperatively (P = 0.010) in group I. The corneal densitometry was 21.86 ± 6.22GSU preoperatively and 21.23 ± 4.29GSU at 12 months postoperatively (P = 0.815) in group II. High corneal maximal densitometry was associated with the thin central corneal thickness (P = 0.027), the presence of haze (P = 0.028), post-keratoplasty (P = 0.004), steep keratometry (P = 0.035).

CONCLUSION:

The incidence of corneal haze was comparable in virgin and post corneal transplant eyes. The Pentacam Scheimflug densitometry can be helpful in the diagnosis of corneal haze; however, the cutoff values need to be studied further in larger studies.

Published: November 2020

PURPOSE:

To determine the prevalence of refractive errors among Saudi adults in Riyadh, Saudi Arabia.

METHODS:

A cross-sectional study was conducted targeting healthy Saudi adults (20–40 years old) at two major gatherings in Riyadh, Saudi Arabia from December 2018 to January 2019. Refractive errors were measured, and data pertaining to age, sex, region of origin, and spectacle use was collected. Clinically significant myopia was defined as SE ≥ -0.50 D, hyperopia as SE ≥ 0.50D, and astigmatism as cylindrical error ≥ 0.50D. Refractive error measurements were assessed using Topcon's Auto-Kerato-Refractometer, KR-800.

RESULTS:

A total of 660 adult individuals (1,319 eyes) were included in this study, of which 321 participants (48.7%) were found to be myopes, 167 subjects (25.2%) were hyperopes, and 438 individuals (66.3%) had astigmatism. With regards to correlations, myopia was highly correlated with being male (P-value = 0.036), belonging to age group 20–25 years (P-value = 0.033), originating from the northern regions of Saudi Arabia (P-value <0.001). Similarly, hyperopia was significantly correlated with being male (P-value = 0.048), age groups 20–25 years (P-value = 0.04), and 31–35 years (P-value = 0.011) and was higher in people from northern region (P-value = 0.011). In contrast, astigmatism was only found to be correlated with age group 36–40 years (P-value = 0.002). Additionally, 71.7% of myopic participants and 76.1% of astigmatic individuals opted not to wear spectacles (P-value <0.001).

CONCLUSION:

In this study, the refractive error with the highest prevalence among Saudis was astigmatism, followed by myopia and hyperopia. Gender, region of origin, and spectacle wear were all observed to be highly correlated with higher rates of refractive error.

Presently the management of glaucoma is limited to lowering of intra-ocular pressure (IOP). Since this modality does not appear to be successful in all cases there is increasing focus on non-IOP lowering medications. Coenzyme Q is a naturally occurring compound similar to vitamins. There are a few reports suggesting the neuroprotective efficacy of this agent in glaucoma models. The present systematic review was undertaken to study the pharmacology, physiology, metabolism and role of Coenzyme Q in glaucoma. An English-language search for relevant items was undertaken using PubMed, Google Scholar, Scopus and other databases. The present review found a positive outcome of Coenzyme Q as a neuroprotectant being reported in all studies. However, the review also found that the majority of studies on Coenzyme Q have been reported by a single group of researchers. In order to have a more wide-ranging impact regarding the efficacy of Coenzyme Q in glaucoma, it would be useful to undertake further multi- center trials.

Геометрические оценки решений квазилинейных эллиптических неравенств
Authors: Kon'kov Andrej Alexandrovich
Published: November 2020

Предположим, что $p>1$ и $p-1 \leqslant \alpha \leqslant p$ - некоторые вещественные числа, а $\Omega$ - непустое открытое подмножество $\mathbb{R}^n$, $n \geqslant 2$. Рассмотрим неравенство
$$
\operatorname{div} A (x, D u)+b (x) |D u|^\alpha\geqslant 0,
$$
где $D=(\partial/\partial x_1, \partial/\partial x_2, …, \partial/\partial x_n)$ - оператор градиента, $A\colon \Omega \times \mathbb{R}^n \to \mathbb{R}^n$ и $b\colon \Omega \to [0, \infty)$ - некоторые функции, причем
$$
C_1|\xi|^p\leqslant\xi A (x, \xi),\quad |A (x, \xi)|\leqslant C_2|\xi|^{p-1},\qquad C_1, C_2=\mathrm{const}>0, \quad p>1,
$$
для почти всех $x \in \Omega$ и всех $\xi \in \mathbb{R}^n$. Для решений этого неравенства получены оценки, учитывающие геометрию $\Omega$. Из этих оценок, в частности, следуют условия регулярности граничной точки.

Authors: UNUTULMAZ Sevim , DULUPÇU Murat Ali
Published: November 2020

İnsanlık tarihinde geniş coğrafyalara yayılan ve toplu ölümlere neden olan pek çok salgın hastalık yaşanmıştır. Bu hastalıkların ortaya çıkmasının önlenmesi, izlenmesi ve kontrol altına alınması yıllarca birincil öneme sahip halk sağlığı sorunu olarak görülmüştür. Temas ağları, enfeksiyonların popülasyonda yayılmasını görselleştirmek, modelleme yaklaşımlarının temelini oluşturmak ve müdahale için kilit bireyleri tanımlamak için kullanılmaktadır. Bu çalışmada bulaşıcı hastalıkların yayılmasını anlamak için sosyal ağ analizlerinin sağladığı olanaklar ele alınmaktadır. Hem epidemiyolojide kullanılan tekniklere hem de sosyal ağ analizinde yeni perspektifler açan son çalışmalara odaklanılmıştır. Sosyal ağ analizi temaslar arasındaki çok sayıda ara bağlantı ve yoğun döngüsel şekilleri göstererek enfekte vaka hastaları ve temaslar arasında yakın ilişkiler olduğunu ortaya koymuştur. Ayrıca temas ağırlıkları kullanılarak, bireysel enfeksiyon riskinin tahmin edilebileceği ve koruyucu aşılama gibi hedefe yönelik müdahalelerin etkin bir şekilde uygulanabileceği görülmüştür. Sosyal ağ analizi aracılığı ile elde edilen kilit bilgiler Kovid-19 denetleyicileri için ileriyi tahmin etmeye olanak sağlayarak salgın hastalıların yayılımını önlemeye yardımcı olabilir.

This study examined the effect of normative learning on employee cognitive engagement. Survey research design was adopted to assess the subject matter. Five hundred and forty-one hundred (541) respondents were surveyed across all the selected pharmaceutical companies in Nigeria with the usage of purposive and stratified sampling technique. Only four hundred and thirty-four (434) copies of questionnaire representing (80.2%) response rate was correctly filled, returned and analysed for this study. Structural Equation Model (AMOS 23) was adopted for the analysis of the effect of normative learning on employee cognitive engagement and efficacy of employee engagement to work and job task. The results from the test of hypotheses showed that normative learning significantly influence employee cognitive engagement (R2= 0.840 p-value = 0.000). The study recommends that management of the selected firms should develop functional systems that ensure transfer of best practices among various areas of work and encourage individual members in teams to have clear understanding of the problem to be addressed. The insights from this study would be of great value to the management of pharmaceutical industry, and other stakeholders to develop and invest in normative learning that will enhance job commitment and engagement of employees
The Invisibility of Labour Trafficking in Spain. A Critical Analysis of Cases and Policies
Authors: Rodríguez López Silvia
Published: November 2020

One of the most remarkable challenges concerning global migration policies nowadays has to do with impeding the trafficking of migrant workers for the purposes of labour exploitation. This paper aims to examine whether Spain has adequately fulfilled its obligations to prevent and prosecute labour trafficking and protect trafficking victims. To do so, it offers a critical analysis of public policies concerning labour trafficking, contrasting them with case-law and data regarding its implementation in practice. Thus, the most recent available data concerning inspection, investigation and prosecution of labour trafficking cases, as well as the identification and protection of labour trafficking victims in Spain is evaluated here. The results highlight the invisibility of human trafficking victims for the purposes of labour exploitation, partly caused by the lack of measures that specifically address this form of trafficking.

Zaman dulu batik dipakai berdasarkan tujuan yang melingkupinya. Banyak orang tertipu dengan harga mahal yang ditawari pembeli menilai batik tulis maupun batik cap yang asli, dihargai jutaan rupiah. Adapun metode penulisan dalam penelitian skripsi ini memakai studi normatif, melalui pendekatan peraturan perundang-undangan ITE dengan batik tulis. Jika diamati tiruan bati alias bukan batik asli karena diproses dengan cara memadukan sablon. Motif batik ditutup menggunakan malam dengan alat printing untuk sablon setelah proses pencelupan warna seperti proses pembatikan. Ketidaktahuan  serta  kesalahan  persepsi  konsumen  yang  menganggap  produk  tekstil printing motif batik adalah sama dengan produk batik, ternyata memberikan kerugian untuk produsen batik dan  konsumen  itu  sendiri.  Omset  penjualan  produsen  batik  menjadi  turun,  karena  konsumen cenderung  membeli  produk  tekstil printing motif  batik  yang  memiliki  harga  jauh    lebih  murah dibanding produk batik dan konsumen menjadi rentan dengan upaya penipuan dari produsen batik yang  tidak  jujur,  yang  menyebutkan  bahwa  produk  yang  dijualnya  tersebut  adalah  produk  batiknamun sebenarnya adalah produk tekstil printing motif batik.
