Coletivo em Silêncio: o encontro que cria um corpo político e produz vida
Authors: Oliveira Paula Gorini
Published: June 2021

Este ensaio é um recorte de uma pesquisa mais ampla, a pesquisa de tese que observa a produção do corpo político como parte da manifestação das lutas contemporâneas. Nesse recorte, apresenta-se um relato de experiência, a partir de minha observação participante em um coletivo feminista de arte e educação, de luta antipunitivista e pelo desencarceramento – o Coletivo em Silêncio. A narrativa do trabalho apresenta também depoimentos, poesias e entrevistas concedidas à autora por mulheres atingidas pelo sistema prisional e de justiça, mulheres que foram historicamente e socialmente estigmatizadas como pessoas que não servem à sociedade e por isso podem ser descartadas. Este trabalho, que assume um caráter ensaístico, procura tornar evidentes estratégias de resistência através de práticas comunicativas e da expressão artística, e, por fim, criar espaço para que as falas dessas mulheres ressoem e possam ser escutadas.

Definimos, como aspectos e categorias de análise das reportagens, a contextualização, os desafios e estratégias de apuração da violência de gênero e cultura do estupro como formas de organização social e questões de saúde pública. Como resultados, reforçamos a necessidade da abordagem feminista no jornalismo para gerar a reflexão pela sociedade, o enfrentamento da violência e da desigualdade de gênero.
Amerika’da Aşırı Sağ Şiddet ve Terörizm
Authors: Kemiksiz Nigar Neşe
Published: June 2021

Amerika’da aşırı sağ şiddetin uzun bir geçmişi bulunmaktadır. İç savaşın ardından Ku Klux Klan Örgütü’nün Afrikalı Amerikalılara ve “işbirlikçi” beyazlara yönelik sistematik ve örgütlü şiddet uygulamaları aşırı sağ şiddetin gelişiminde önemli rol oynamıştır. 1960’lardan sonra neo-Nazilerin, Hıristiyan Kimlik doktrinine bağlı grupların ve hükümet karşıtlarının aşırı sağ sahnesine girmesi, aşırı sağda ideolojik ve örgütsel çeşitliliğe yol açmıştır. Amerika’daki aşırı sağ şiddet ve teröre ilişkin veriler, sağ kanat aşırılıkçı saldırı veya saldırı planlarının ABD’deki tüm terörist olayların çoğunluğunu oluşturduğunu, 2013’ten bu yana büyük ölçüde artmış olduğunu ve ölümcül saldırıların büyük bölümünün -11 Eylül terör eylemleri dışında- sağ kanat saldırılardan kaynaklandığını göstermektedir. 2020 başkanlık seçimlerinin ardından yaşanan Kongre binasını işgal girişimleri, aşırı sağ şiddetin boyutlarını ortaya koymuştur. Aşırı sağ şiddet ve terör eylemlerindeki düzenli artışı gösteren veriler ve son yıllarda artan kutuplaşmanın yanı sıra, COVID 19 salgınının yol açtığı ekonomik ve sosyal problemler ışığında Amerika’da aşırı sağ şiddet ve terörünün yükselişini sürdüreceği düşünülmektedir.

Published: June 2021

Proses pembangunan membutuhkan keterlibatan perempuan. Perempuan sebagai bagian dari masyarakat memiliki peran penting dalam perubahan sosial. Peningkatan peran perempuan salah satunya dipengaruhi oleh kebijakan yang dikeluarkan pemerintah. Ketika kebijakan yang dikeluarkan pemerintah belum dipahami oleh perempuan menjadikannya sebagai kelompok yang terkungkung dalam ketidaknyamanan. Permasalahan tersebut dapat ditanggulangi dengan mengadakan pendekatan dengan perempuan dalam kelompoknya melalui literasi dalam bentuk sosialisasi, diskusi dan pelatihan. Perempuan yang tergabung dalam PKK terutama yang berusia lebih dari 50 tahun dari Desa Wirogunan Kecamatan Kartasura Kabupaten Sukoharjo belum mampu memahami kebijakan pemerintah terkait pencegahan terhadap penularan Virus Corona. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pemahaman anggota PKK terhadap penyebaran virus yang berskala internasional, kebijakan pemerintah dan melatih menggunakan gawai secara bijak agar bisa memilah informasi secara benar. Metode yang digunakan dalam kegiatan ini berupa sosialisasi dan pelatihan. Kegiatan tersebut� berjalan lancar dan sesuai rencana. Anggota PKK mengalami perubahan positif yakni semakin paham sekaligus menaati kebijakan pemerintah yang berwujud peraturan serta lebih bijaksana dalam menggunakan gawai.The development process requires the involvement of women. Women as part of the community have an important role in social change. One of the increasing roles of women is influenced by government�s policies. When the government�s policies are not yet understood by women, making them a group that is confined in discomfort. These problems can be overcome by approaching women in their groups through literacy in the form of socialization, discussion and training. Women who are members of the PKK especially those aged over 50 years from Wirogunan Village, Kartasura District, Sukoharjo Regency have not been able to understand government policies related to prevention of Corona Virus transmission. This community service activity aims to increase PKK members' understanding of the spread of the virus on an international scale, government policy and train to use smartphone wisely so that they can sort out information correctly. Method that used in this activity are socialization and training. This activity went well and according to the plan. PKK members experienced positive changes, which increasingly understood and obeyed government policies in the form of regulations and wiser in using smartphone.

The ecotourism potential of the beach area in Bone Bolango regency, if developed optimally, is very high. Ecotourism development is a tourism activity that incorporates the principles of environment-friendly attitudes. It emphasizes the aspects of nature conservation, empowerment of the local community’s economic, social, and cultural competence, as well as education. Botutonuo beach is among the coastal areas in Bone Bolango regency with high ecotourism potential. The present study aimed to analyze the ecotourism potential of Botutonuo beach based on the physical, sociocultural, economic, and institutional parameters. It employed an ecological-spatial approach by involving the Geographic Information System (GIS). The research method comprised field observation; the data were retrieved by field measurement, interview, and questionnaire. The data were analyzed in a quantitative manner with descriptive statistical analysis, scoring analysis, and qualitative descriptive analysis to result in the final evaluation score of the site’s ecotourism potentials. The analysis result on the site’s physical parameters (vegetation, environmental hygiene, materials, and water brightness) indicated that the Botutonuo beach has high potential. The same criteria were also given in other physical parameters that consisted of distance, facilities, accessibility, and site attractiveness. Moreover, high ecotourism potential was also shown by the site’s other parameters (institutional, sociocultural, economic, and environmental parameters). The site’s high ecotourism potential was due to the beach’s characteristics. The site is a sandy beach that is naturally formed. On top of that, the community’s contribution to constructing tourism facilities was influential in boosting the ecotourism potentials.

The mediating role of hotel employees’ job satisfaction and performance in the relationship between authentic leadership and organizational performance
Authors: Kaštelan Mrak Marija , Grudić Kvasić Sanda
Published: June 2021

Authentic leadership is a positive leadership theory, conceptualized under the influence of positive psychology and positive organizational behaviour movement. Although it has become a recognized leadership theory, it is still somewhat neglected in the hospitality literature. To address this gap, the paper seeks to develop and test a conceptual model linking authentic leadership to organizational performance in the hospitality context. Hypotheses were tested using hierarchical multiple regression analysis on a sample of 226 employees from 24 hotels in Croatia. The research results confirmed the positive impact of authentic leadership on hotels’ operational performance, which was mediated by followers’ job satisfaction and performance. There was no empirical support for the hypothesized impact of authentic leadership on hotels’ financial performance. The findings suggest that authentic leadership behaviours, together with positive organisational settings, characterized by flexible organizational structure, are more likely to enhance desirable employees’ attitudes and behaviours, resulting in improved organizational performance.

Food quality scores and indexes are simple but effective tools for the overall diets assessment. It has been shown that they are closely linked to the suitability of these diets for nutritional recommendations, and that they correctly reflect their quality. These indexes have also proven to be good indicators of household food security, as well as children nutritional status, especially their growth. The use of these scores and indexes has been very successful in both developed, and developing countries, after several efforts to harmonize their calculation methods. The diet quality index methodology focuses on dietary diversity, or on adequacy to nutritional recommendations. Among these, several scores, and indexes have been developed to assess adherence to the Mediterranean diet. The aim of this review is to present the different nutritional scores and indexes developed worldwide, and in the Mediterranean region to assess the diets quality.

Introduction. Essential oils and their components are currently of great interest as a potential source of highly bioactive natural molecules. They are being studied for their possible use as safe alternative for food protection against oxidation and microbial spoilage. Objective. This study aimed on the phytochemical prospection of Thymus capitatus and Rosmainus officinalis essential oils and their oral toxicity evaluation. Material and methods. Chemical analysis of tested essential oils was carried out using gas chromatography combined to mass spectroscopic (GC-MS). Their safety limit was evaluated by acute toxicity. The antioxidant activity was estimated using in vitro methods. The antimicrobial activity was evaluated against twelve pathogenic germs. Results. Results showed that carvacrol and 1,8-cineol were the major compounds of Thymus capitatus and Rosmarinus officinalis essential oils. Acute toxicity results exhibited that both tested essential oils were inoffensive at 2000 mg/kg. Additionally, Thymus capitatus essential oil presented higher antioxidant activity than Rosmarinus officinalis: 2,2-diphényl-1-picrylhydrazyl (DPPH) assay results showed lower IC50 for Thymus capitatus essential oil than Rosmarinus officinalis. Concerning the antimicrobial results, Thymus capitatus essential oil presented greater efficacy than R. officinalis. Indeed, the minimal growth inhibition diameter generated by thyme essential oil exceeded 38 mm (except for Salmonella typhirium) and reached 60 mm (against C. tropicalis and C. albicans). However, the maximal growth inhibition diameter generated by R. officinalis essential oil was limited to 36 mm (against Shigella sonnei). Conclusion. Overall, Thymus capitatus and Rosmarinus officinalis essential oils have strong potential applicability for pharmaceutical industries.
Uchyot and Foucault: Drug Users and Migrants in Post-Soviet Central Asia and Russia
Authors: Turaeva Rano , Turaeva Muyassar
Published: June 2021

In this paper, we unpack the uchyot (“registration”) system using Foucault’s regime-based approach. Uchyot is a Soviet tool for controlling populations by requiring them to register personal information and then sharing this information with the relevant state institutions. This paper explores how uchyot is used to control drug users in Uzbekistan and Central Asian migrants in Russia. It argues that social and economic pressures, combined with strict policies, push unwanted citizens and migrants to engage in risky behaviors or into the shadows of informality and illegality.
Central Asian Regionalism or Central Asian Order? Some Reflections
Authors: Costa Buranelli Filippo
Published: June 2021

This article reflects on how the concept of regionalism has been used to explain and interpret Central Asian politics since independence. It argues that regionalism, often a norm-laden analytical category based on Eurocentric assumptions, tends to paint the region as “failed” and regional states as incapable of institutionalizing multilateral relations. In its place, the article suggests the concept of order, which is more neutral and—through its focus on the operation of sovereignty, diplomacy, international law, authoritarianism, and great power management—is able to incorporate elements of both the conflict and cooperation that have marked the region’s politics since 1991.
STEM Pathways of Rural and Small-Town Students: Opportunities to Learn, Aspirations, Preparation, and College Enrollment
Authors: Saw Guan K. , Agger Charlotte A.
Published: June 2021

Using the nationally representative High School Longitudinal Study of 2009 (HSLS:09), this study documents that rural and small-town students were significantly less likely to enroll in postsecondary STEM (science, technology, engineering, and mathematics) degree programs, compared with their suburban peers. This study also shows that schools attended by rural and small-town students offered limited access to advanced coursework and extracurricular programs in STEM and had lower STEM teaching capacity. Those opportunities to learn in STEM were linked to the widening geographic gaps in STEM academic preparation. Overall, our findings suggest that during high school rural and small-town students shifted away from STEM fields and that geographic disparities in postsecondary STEM participation were largely explained by students’ demographics and precollege STEM career aspirations and academic preparation.
BIOGEOCHEMICAL AND MECHANICAL CHARACTERIZATION OF THE LANDFILL FRACTION GENERATED BY MECHANICAL WASTE SORTING
Authors: Andersson Emelie , Jobs Marit , Lagerkvist Anders , Elfgren Lennart
Published: June 2021

As the resource recovery from mixed waste streams are performed, new mixed waste streams are generated. Some of these waste streams does not fit well to existing waste management options, for example, they may hold a to low heating value to sustain combustion and they may have a too high carbon content to be accepted at non-hazardous landfills. Also various health and pollution risks may arise as well as practical handling issues due to the physical properties of such wastes.

One such waste is the under sieve fraction generated when recovering metals and fuel from mixed waste streams using mechanical and magnetic separation tools. Such mechanical sorting is typically used for mixed wastes of different properties and particle sizes, such as houshold bulky wastes, construction and demolition waste, and at landfill mining materials.
In this work, we examine the properties of one case of mechanical sorting of bulky wastes, including construction and demolition wastes. We analyse a broad spectrum of chemical, physical, and mechanical properties as well as some biological. Based on the data we develop recommendations for landfilling, what potential problems might arise and how to counteract them.
PYROLYSIS OF SOLID WASTE AND ITS COMPONENTS IN A LAB SCALE INDUCTION-HEATING REACTOR
Authors: Sosa Oscar , Valin Sylvie , Thiery Sébastien , Salvador Sylvain
Published: June 2021

The present study investigates the thermochemical conversion of Solid Recovered Fuel (SRF), represented by selected “model materials”. A laboratory-scale induction heated device was specifically developed to achieve fast pyrolysis conditions close to those encountered in a fluidized bed reactor. The novel device can handle up to 5 grams of solid, allowing fast heating rates (near 70°C/s) and a homogeneous distribution of temperature all along the reactor. Pyrolysis tests of a SRF sample and four model materials (Polyethylene, Polyethylene Terephthalate, beech wood, cardboard) were performed at 800°C. The yield and composition of the produced gas for each sample were determined. Experimental results will help to elucidate the relation between the initial components of waste derived fuels and the obtained reaction products.
Existence of an initial value problem for time-fractional Oldroyd-B fluid equation using Banach fixed point theorem
Authors: TRI Vo Viet
Published: June 2021

In this paper, we study the initial boundary value problem for time-fractional Oldroyd-B fluid equation. Our model contains two Riemann-Liouville fractional derivatives which have many applications, for example, in viscoelastic flows. For the linear case, we obtain regularity results under some different assumptions of the initial data and the source function. For the non-linear case, we obtain the existence of a unique solution using Banach's fixed point theorem.

COVID-19 impacts the daily lives of millions of people. This radical change in our daily activities affected many aspects of life, but acted as well as a natural experiment for research into the spatial distribution of 911 calls. We analyse the impact of the COVID-19 measures on the spatial pattern of police interventions. Crime is not uniformly distributed across street segments, but how does COVID-19 affect these spatial patterns? To this end, a proportion differences spatial point pattern test is applied to compare the similarity of the patterns of incidents before, during, and after the first lockdown in Antwerp, Belgium. With only essential mobility being allowed, the emergency call pattern has not significantly changed before, during or after this lockdown, however, a qualitative shift in police officer’s daily work may have had an effect on the daily operation of the Antwerp police force.
Differential expression of aurora kinase A in human epithelial ovarian cancer.
Authors: Mamoor Shahan
Published: June 2021

Epithelial ovarian cancer (EOC) is the most lethal gynecologic cancer (1). We performed discovery of genes associated with epithelial ovarian cancer and of the high-grade serous ovarian cancer (HGSC) subtype, using published microarray data (2, 3) to compare global gene expression profiles of normal ovary or fallopian tube with that of primary tumors from women diagnosed with epithelial ovarian cancer or HGSC. We identified the gene encoding aurora kinase A, AURKA, as among the genes whose expression was most different in epithelial ovarian cancer as compared to the normal fallopian tube. AURKA expression was significantly higher in high-grade serous ovarian tumors relative to normal fallopian tube. AURKA expression correlated with overall survival in patients with ovarian cancer. These data indicate that expression of AURKA is perturbed in epithelial ovarian cancers broadly and in ovarian cancers of the HGSC subtype. AURKA may be relevant to pathways underlying ovarian cancer initiation (transformation) or progression.

Social nudges for vaccination: How communicating herd behaviour influences vaccination intentions

Objectives: This Registered Report attempted to conceptually replicate the finding that communicating herd immunity increases vaccination intentions (Betsch, et al., 2017, Nat. Hum. Behav., 0056). An additional objective was to explore the roles of descriptive social norms (vaccination behaviour of others) and the herd-immunity threshold (coverage needed to stop disease transmission).Design: An online experiment with a 2 (herd-immunity explanation: present vs. absent) x 3 (descriptive norm: high vs. low vs. absent) x 2 (herd-immunity threshold: present vs. absent) between-subjects fractional design.Methods: Sample consisted of 543 people (aged 18–64) residing in the United Kingdom. Participants first received an explanation of herd immunity emphasising social benefits (protecting others) in both textual and animated-infographic form. Next, they were faced with fictitious information about the disease, the vaccine, their country’s vaccination coverage (80% or 20%), and the herd-immunity threshold (90%). Vaccination intention was self-rated.Results: Compared to the control, communicating social benefits of herd immunity was effective in increasing vaccination intentions (F(1,541) = 6.97, p = .009, Partial Eta-Squared = 0.013). Communicating the descriptive norm or the herd-immunity threshold alongside the herd-immunity explanation demonstrated no observable effect.Conclusion: Communicating social benefits of herd immunity increased self-reported vaccination intentions against a fictitious disease, replicating previous findings. Although this result is positive, the practical relevance may be limited. Further research into the effect of social nudges to motivate vaccination is required, particularly with respect to the recent pandemic context and varying levels of vaccine hesitancy.

Computational Electromagnetics for Efficient Control Design of Massive MIMO and Beyond

As Multiple Inputs Multiple Outputs (MIMO) is becoming one of the enable techniques in modern wireless communication like 5G/6G and beyond, it is important to design efficient controls for the MIMO antenna arrays to realize critical functions such as high-throughput communication and beamforming. Efficient and rigorous Computational Electromagnetics (CEM) algorithms are key for such control design problem, especially for massive MIMO antenna arrays and beyond. Here we present such universal Fast Fourier Transform (FFT) based iterative CEM algorithm for efficient control design of massive MIMO antenna array and beyond, for example Reconfigurable Intelligent Surface and Large Intelligent Surface (RIS/LIS) MIMO. Our FFT-based iterative CEM algorithm is universal and works for both discrete MIMO and quasi-continuous RIS/LIS MIMO under various realistic amplitude and phase control constraints. It makes use of the translation invariant property of the dyadic function of the MIMO antenna arrays and compute the convolution operator in the spectral domain. Then it updates the control parameters iteratively under the control amplitude and control phase constraints, with the incident field and the target output field as inputs. Due to the use of FFT, the computational effort of the algorithm scales as NlogN for N = Nx Ny MIMO antennas, compared to N^3 of the direct solving method of the linear equation. Numerical simulation for 6G beamforming of both discrete MIMO and RIS/LIS MIMO under various control design constraints has been carried out to show the efficiency of the algorithm.
Mind wandering at encoding, but not at retrieval, disrupts one-shot stimulus-control learning
Authors: Whitehead Peter S. , Mahmoud Younis , Seli Paul , Egner Tobias
Published: June 2021

The one-shot pairing of a stimulus with a specific cognitive control process, such as task switching, can bind the two together in memory. The episodic control-binding hypothesis posits that the formation of temporary stimulus-control bindings, which are held in event-files supported by episodic memory, can guide the contextually appropriate application of cognitive control. Across two experiments, we sought to examine the role of task-focused attention in the encoding and implementation of stimulus-control bindings in episodic event-files. In Experiment 1, we obtained self-reports of mind wandering during encoding and implementation of stimulus-control bindings. Results indicated that, whereas mind wandering during the implementation of stimulus-control bindings does not decrease their efficacy, mind wandering during the encoding of these control-state associations interferes with their successful deployment at a later point. In Experiment 2, we complemented these results by using trial-by-trial pupillometry to measure attention, again demonstrating that attention levels at encoding predict the subsequent implementation of stimulus-control bindings better than attention levels at implementation. These results suggest that, although encoding stimulus-control bindings in episodic memory requires active attention and engagement, once encoded, these bindings are automatically deployed to guide behavior when the stimulus recurs. These findings expand our understanding of how cognitive control processes are integrated into episodic event files.
Demographic theory and population ethics
Authors: Kolk Martin
Published: June 2021

Demographic theory is concerned with how population systems regulate themselves given available resources and external shocks to population size. This chapter provides an overview of demographic theory, focusing specifically on relationships between population size, population growth, and welfare. It then discusses four implications of demographic theory for population ethics. Speaking broadly, these four implications concern (1) the overreliance by some population ethicists on Malthusian assumptions about the average welfare of population declining with increasing population size, (2) the likelihood of certain hypothetical scenarios that feature in thought experiments used in population ethics, (3) the prioritization of extinction risks by population ethicists, and (4) the patterns of intergenerational and intertemporal inequality that population ethicists may anticipate over the long run. The chapter closes with a discussion of demographic theory in relation to historical and future demographic change.
Vanishing borders: ethnicity and trade costs at the origin of the Yugoslav market
Authors: Chilosi David , Nikolic Stefan
Published: June 2021

This article exploits the creation of a paradigmatic multi-ethnic state, Yugoslavia, to examine if, to what extent, and why the effect of ethnic ties on trade costs changes over time. We compile and examine a panel of over 550,000 inter-urban price gaps spanning the area of Yugoslavia in the decades before and after the Yugoslav uni?cation of 1918. Controlling for observable trade costs, we ?find that crossing the border between Serbia and Austria-Hungary signifi?cantly increased price gaps before the First World War. Ethno-religious differences explained a large share of this border effect in pre-uni?cation Yugoslavia, but their influence vanished over time. This decline began about twelve years before the uni?cation, and is visible both in city-pairs that were separated by the pre-war border and in those that were not. These patterns suggest that nation-building, rather than a weakening incentive to rely on private order institutions, was the main unifying factor.
