Published: March 2021

The cusp–core problem is one of the main challenges of the cold dark matter paradigm on small scales; the density of a dark matter halo is predicted to rise rapidly toward the center as ρ(r) ∝ r

α
with α between −1 and −1.5, while such a cuspy profile has not been clearly observed. We have carried out the spatially resolved mapping of gas dynamics toward a nearby ultradiffuse galaxy (UDG), AGC 242019. The derived rotation curve of dark matter is well fitted by the cuspy profile as described by the Navarro–Frenk–White model, while the cored profiles including both the pseudo-isothermal and Burkert models are excluded. The halo has α = −(0.90 ± 0.08) at the innermost radius of 0.67 kpc, M
halo = (3.5 ± 1.2) × 1010
M
⊙, and a small concentration of 2.0 ± 0.36. The UDG AGC 242019 challenges alternatives of cold dark matter by constraining the particle mass of fuzzy dark matter to be <0.11 × 10−22 or >3.3 × 10−22 eV, the cross section of self-interacting dark matter to be <1.63 cm2 g−1, and the particle mass of warm dark matter to be >0.23 keV, all of which are in tension with other constraints. The modified Newtonian dynamics is also inconsistent with a shallow radial acceleration relationship of AGC 242019. For the feedback scenario that transforms a cusp to a core, AGC 242019 disagrees with the stellar-to-halo mass ratio dependent model but agrees with the star formation threshold dependent model. As a UDG, AGC 242019 is in a dwarf-sized halo with weak stellar feedback, late formation time, normal baryonic spin, and low star formation efficiency (SFR/gas).

Ultra-diffuse galaxies have generated significant interest due to their large optical extents and low optical surface brightnesses, which challenge galaxy formation models. Here we present resolved synthesis observations of 12 H i-bearing ultra-diffuse galaxies (HUDs) from the Karl G. Jansky Very Large Array, as well as deep optical imaging from the WIYN 3.5 m telescope at Kitt Peak National Observatory. We present the data processing and images, including total intensity H i maps and H i velocity fields. The HUDs show ordered gas distributions and evidence of rotation, important prerequisites for the detailed kinematic models of Mancera Piña et al. We compare the H i and stellar alignment and extent, and find that H i extends beyond the already extended stellar component and the H i disk is often misaligned with respect to the stellar one, emphasizing the importance of caution when approaching inclination measurements for these extreme sources. We explore the H i mass–diameter scaling relation, and find that, although the HUDs have diffuse stellar populations, they fall along the relation with typical global H i surface densities. This resolved sample forms an important basis for more detailed study of the H i distribution in this extreme extragalactic population.
On Strong Correlation between Shifted Velocity and Line Width of Broad Blueshifted [O iii] Components in Quasars
Authors: Zhang XueGuang
Published: March 2021

We report strong linear correlation between shifted velocity and line width of the broad blueshifted [O iii] components in Sloan Digital Sky Survey (SDSS) quasars. Broad blueshifted [O iii] components are commonly treated as indicators of outflows related to a central engine; however, it is still an open question whether the outflows are related to central accretion properties or related to local physical properties of narrow emission-line regions (NLRs). Here, the reported strong linear correlation with Spearman rank correlation coefficient 0.75 can be expected under the assumption of active galactic nuclei (AGNs) feedback-driven outflows, through a large sample of 535 SDSS quasars with reliable blueshifted broad [O iii] components. Moreover, there are very different detection rates for broad blueshifted and broad redshifted [O iii] components in quasars, and no positive correlation can be found between shifted velocity and line width of the broad redshifted [O iii] components, which provides further and strong evidence to reject the possibility of local outflows in NLRs leading to the broad blueshifted [O iii] components in quasars. Thus, the strong linear correlation can be treated as strong evidence for the broad blueshifted [O iii] components being better indicators of outflows related to central engine in AGNs. Furthermore, rather than central black hole masses, Eddington ratios and continuum luminosities have key roles in the properties of the broad blueshifted [O iii] components in quasars.

Published: March 2021

The spatiotemporal variations of megazoobenthos on soft bottoms in Buena Vista (BV) and San Juan de Los Remedios (SJR) bays, Cuba, were assessed to infer the effects of the elimination of bottom trawl fisheries and the creation of protected areas. Data were collected at 11 sites in 2010-2013 (six routines and five exploratories) and 11 sites in 2014-2017 (four routines and seven exploratories). Samples were obtained by dredging. Mollusks were the most frequent and diverse group, followed by echinoderms and crustaceans. Total density (7.60 ind m-2) and biomass (15.82 g m-2) of the benthic community were highest in SJR in 2015. Although total biomass was lower at BV (t = 2.21; P = 0.032), there were no significant differences in density between bays (t = 0.77; P = 0.444). The site with a lower total density and biomass was located at BV. There were no differences between years except at one site, where density increased between 2010 and 2017. Total density and biomass were not significantly different inside and outside of the Zone Under Special Regime of Use and Protection (ZUSRUP) at the beginning of the sampled period. However, both density and biomass were significantly higher within the ZUSRUP at the end (2017), which suggests this protected area’s effectivity. The progressive increase in density at one site and greater density and biomass values at SJR, where bottom trawl fisheries were more intensive, suggest eliminating bottom trawl nets may have contributed to the benthic fauna recovery.

Published: March 2021

The study of forest regeneration allows the diagnosis of conservation status of fragments and estimating population parameters that are essential for management projects. This study evaluated the structure, diversity and dynamics of the tree regenerating component of a remnant of mixed ombrophilous forest, aiming to support management actions for this forest type. The study was developed at the Parque Estadual das Araucárias (PEAR), located in the western region of the state of Santa Catarina, southern Brazil. A total of 100 plots of 25 m2 (0.25 ha) were allocated, all individuals with height ≥ 1.0 m and DBH < 5 cm were sampled. Shannon’s diversity index (H’), Pielou’s equability index (J) and total natural regeneration rate (TNR) were estimated. We sampled 1,425 individuals from 99 species and 39 families, with an estimated total density of 5,700 individuals by hectare. The richest families were Fabaceae (13), Myrtaceae (10) and Lauraceae (7). The H’ was 3.76 and the J was 0.80. The TNR rate ranged from 0.05 to 8.12%, highlighting Trichilia elegans, with the highest rate and Araucaria angustifolia with low potential for natural regeneration. The analysis of the results indicated a high diversity in the regenerating component of the PEAR compared to other studies, probably because the area presents itself as a successional mosaic due to past disturbances.
Négocier et contester au Conseil des droits de l’homme des Nations Unies
Authors: Albaret Mélanie
Published: March 2021

À partir d’un travail de recherche empirique mené au Conseil des droits de l’homme (CDH) (observation directe de la 41 e  session du CDH, discussions informelles avec des acteurs, entretiens semi-directifs), je démontre que la forme des négociations au CDH participe de l’euphémisation de la contestation, de son intégration dans le jeu classique des négociations, ce qui permet au jeu de continuer de se dérouler malgré les conflits. Le contexte de négociation genevois se distingue de celui de New York qui paraît moins prévisible aux acteurs. Couplée à la relative ouverture du CDH et à la fluidité des acteurs, cette configuration favorise l’expression de la contestation par les prises de parole (Hirschman, 1995). Celles-ci n’interrompent pas les négociations qui se poursuivent, même si elles se déplacent vers d’autres enjeux, dans d’autres lieux comme à New York, ce qui conduit à réinscrire ces processus dans un contexte structurel plus large (Strauss, 1978). Ce faisant, je mets en avant que ce qui se joue au CDH n’est ni strictement genevois, ni même uniquement lié aux droits humains. Se renégocient constamment l’« ordre onusien » et ses caractéristiques hiérarchiques, interétatique et libérale.
Uncertainty propagation and sensitivity analysis: results from the Ocular Mathematical Virtual Simulator
Authors: Prud'homme Christophe , Sala Lorenzo , Szopos Marcela
Published: March 2021

We propose an uncertainty propagation study and a sensitivity analysis with the Ocular Mathematical Virtual Simulator, a computational and mathematical model that predicts the hemodynamics and biomechanics within the human eye. In this contribution, we focus on the effect of intraocular pressure, retrolaminar tissue pressure and systemic blood pressure on the ocular posterior tissue vasculature. The combination of a physically-based model with experiments-based stochastic input allows us to gain a better understanding of the physiological system, accounting both for the driving mechanisms and the data variability.
Covid‑19, réseaux sociaux et culture pop dans la péninsule Arabique
Authors: Lagrange Frédéric
Published: March 2021

La crise pandémique qui s’est abattue sur le monde depuis février 2020 s’est traduite, dans les pays de la péninsule Arabique comme ailleurs, en une grande diversité de productions culturelles médiatisés : chansons, poèmes, plaisanteries, sketches vidéos comiques, mèmes internet, programmes de divertissement diffusés sur les réseaux sociaux ou sur les chaines de télévision officielles et satellitaires, s’inscrivant dans la « culture populaire digitale » de la région. Certaines reflètent les politiques des États face à l’urgence, relayées par des artistes et des « influenceurs » au service spontané ou commandé des autorités. D’autres laissaient observer des réactions individuelles à la crise, exprimant (dans les limites tolérables par une surveillance pointilleuse des discours diffusés) la peur, l’ennui, ou une attitude sarcastique sur les comportements de sociétés obligées de bouleverser leurs habitudes. Que disent ces vidéos, ces mèmes ou chansons de propre aux sociétés de la péninsule Arabique ? Si une partie reproduit dans une déclinaison locale des thématiques planétaires, d'autres formes sont davantage régionales : les « chansons‑corona », sur un ton martial, satirique ou pathétique ; les plaisanteries sur la présence des hommes dans l’espace domestique privé homosocial, ou encore l’encodage du rapport local‑étranger qu’on y retrouve, que l’étranger soit « de l’intérieur », comme le travailleur immigré, qu’il soit le voisin régional allié ou ennemi, ou enfin celui par qui le mal arrive ou qu’il frappe, dans un ailleurs lointain. Cet essai analyse comment ces productions traduisent ou négocient leur décodage des politiques étatiques et des défis posés par la présence de ces « citoyens impossibles » (Neha Vora) dans les monarchies de la région ayant adopté un modèle de gestion des migrations transnationales anti-intégrateur devant une menace sanitaire plaçant l’ensemble de la population face à un même péril.
Digital Business Transformations
Authors: Matricano Diego
Published: March 2021

This chapter is designed with the aim of analyzing digital business transformations (i.e., digital transformations that companies decide to start in order to respond to market changes). Nowadays, these changes are due to the affirmation of a new paradigm of doing business that is strongly characterized by the role of information and communications technologies (ICT) and information and communication infrastructures (ICI). This has led to the point that digital business transformations are increasingly being considered as a topic exclusively related to information technology and engineering fields of research. In contrast with the above promise, the present research aims to investigate digital business transformations according to a managerial perspective that is often sacrificed in practice. The preponderant role of technologies often leads—in an incorrect way—to neglect the basic concepts of management that, on the other hand, persist in change and, indeed, constitute the backbone of change itself.

Technological breakthroughs are the reasons for industrial revolution to occur. However, it may take time to exert its effects on social and technological domains. Artificial intelligence is the branch of computer science which tries to replicate human intelligence in machines that are programmed to think like humans and mimic their actions. It is acquiring increasing importance in industrial application, revolutionizing the entire industrial system enough to be referred as “Fourth Industrial Revolution.” This chapter describes the impacts of artificial intelligence on the economy and society at large. Specifically, it analyzes the enablers and barriers behind the automatization of the working force and how the digital transformation may entail opportunities and challenges for the current economic and working dynamics as well as for society in general.

Published: March 2021

Modern supply chain applications are complex systems that play an important role in many different sectors. Supply chain management systems are implemented to handle increasing complexity and flows of goods. However, most of these systems are also increasing the complexity of providing trust and a global view of transactions in a distributed supply chain system. Blockchain technology introduces a new architectural style to support the traceability and trust of transactions performed by participants in a network. This chapter uses this emerging technology to realize a supply chain use case from JLP Meats in the UK with improved transparency, trust, and end-to-end querying while discussing potential challenges of realizing large-scale enterprise blockchain applications. The process of farm-to-fork is implemented and tested for traceability, item recall, block analysis, congestion enabling food safety, and sustainable agriculture. Potential challenges are highlighted in complex supply chains that need heterogeneous trade compliance and scalability.
Effect of MnZn Ferrite Nanofluids on the Wettability and Oil-Water Interfacial Tension
Authors: Mokhtar Nurul Afiqah Mohd , Guan Beh Hoe
Published: March 2021

MnZn Spinel ferrite with the chemical formula of MnxZn1-xFe2O4 (x = 0, 0.25, 0.5, 0.75, 1.0) were synthesized by a sol-gel auto-combustion method. Structural and morphological properties of synthesized samples were characterized by X-ray diffraction (XRD) and Field Emission Microscopy (FESEM). XRD patterns revealed characteristic peaks corresponding to spinel Mn-Zn ferrite structures. In addition, the structural analysis demonstrates that the average crystallite size of the synthesized samples varied in the range of 30.0-40.0 nm. The FESEM micrographs reveal agglomerated particles with particles size ranging from 60-80nm. Interfacial tension (IFT) and contact angle measurement for MnZn ferrite nanofluids were performed. The results showed that the use of MnZn ferrite nanofluid significantly decrease the oil-water IFT and contact angle.
Evaluation of 3-D Computational Model of Oscillating Water Column Converter with Constructal Design with Three Degrees of Freedom and Limited Chimney Height

Published: March 2021

Theoretically, ocean waves contain enough mechanical energy to supply the entire world’s demand and, as of late, are seen as a promising source of renewable energy. To this end, several different technologies of Wave Energy Converters (WEC) have been developed such as Oscillating Water Column (OWC) devices. OWCs are characterized by a chamber in which water oscillates inside and out in a movement similar to that of a piston. This movement directs air to a chimney where a turbine is attached to convert mechanical energy. The analysis conducted was based on the Constructive Design Method, in which a numerical study was carried out to obtain the geometric configuration that maximized the conversion of wave energy into mechanical energy. Three degrees of freedom were used: the ratio of height to length of the hydropneumatic chamber (H1/L), the ratio of the height of the chimney to its diameter (H2/d) and the ratio of the width of the hydropneumatic chamber to the width of the wave tank (W/Z). A Design of Experiments (DoE) technique coupled with Central Composite Design (CCD) allowed the simulation of different combinations of degrees of freedom. This allowed the construction of Response Surfaces and correlations for the efficiency of the system depending on the degrees of freedom (width and height of the chamber), as well as the optimization of the system based on the Response Surfaces.

Environmental concern has encouraged development related to polluted water treatment. Produced water originated from oil exploration has been submitted to different separation processes such as settling tanks, floaters, two-phase and three-phase separators, hydrocyclones, and membranes. On the use of membranes, the goal is to separate soluble components from solutions based on the size, charge, shape, and molecular interactions between the solute and membrane surface. In the present work, a numerical study was developed on the oil-water mixture separation process using a porous ceramic membrane module. The mathematical model used in this research is composed of mass and momentum conservation equations coupled to Darcy ́s law and SST k-ω turbulence model. Simulations were carried out employing the Ansys CFX commercial software. Results of the pressure, velocity, oil concentration distribution inside the device and membrane are presented and discussed. The results showed that the geometric aspects of the proposed microfiltration module and the membrane distribution within the separation module had a significant influence on the hydrodynamic flow leading to polarized layer dispersion.
Thermal Conductivity and Oxygen Tracer Diffusion of Yttria Stabilized Zirconia by Molecular Dynamics
Authors: Momenzadeh Leila , Belova Irina V. , Murch Graeme E.
Published: March 2021

One of the most technologically beneficial engineering ceramics is yttria stabilized zirconia (YSZ). As a result, research interest about YSZ has been intensive for many years. In this study, the lattice thermal conductivity and oxygen diffusion coefficient of YSZ are investigated at different temperatures (from 700 K to 1300 K) and zero pressure with the Green-Kubo formalism. We find that the lattice thermal conductivity decreases as the temperature increases, particularly at low temperatures and it shows a slightly temperature independence at high temperatures. The results demonstrate that the YSZ has quite a low thermal conductivity compared with pure zirconia. We also show that the oxygen tracer diffusion coefficient, as calculated from the mean square displacements, has an activation energy of 0.85eV.

Published: March 2021

Bushmint (Hyptis suaveolens Poit) is a weed with pesticidal properties that have been explored in managing pests of agricultural and medicinal importance. The objective of this study was to evaluate the repellence ability of Hyptis suaveolens to prevent infestation of stored maize grain seed. The study involved evaluation of the olfactory responses of adult weevil to maize (Zea mays L.) grains treated with 5, 10, 15 and 20% concentrations of leaf powder (LP) and methanol extract (ME) of Hyptis suaveolens in the laboratory, with a static air four-chamber olfactometer. Also, the insecticidal effects of the substances on adult mortality and oviposition on maize grains treated with LP and ME were determined in a completely randomised design, with four replicates. The number of weevils in ME chambers decreased with increase in concentration of extracts; while the LP chambers had consistently fewer weevils with numbers, ranging from 2.5 to 3.75. Adult mortality in maize treated with LP was the least and varied between 0.00 (15% concentration) and 2.54% (20% concentration). Maize grains with ME caused significant mortalities that ranged from 65.50% at 15% concentration to 94.92% at 10% concentration. More eggs (3.5 to 5.75) were laid on maize with LP compared with ME treated maize. Generally, ME was richer in phytochemicals than LP. Hyptis suaveolens repellence manifested more in the form of LP than as ME; though ME caused more adult mortality and reduced oviposition than LP.

Published: March 2021

Lipase is a hydrolytic enzyme and commonly used for the diagnosis of pancreatitis with amylase. Except for pancreatitis, lipase is elevated in many clinical conditions such as hepatobiliary disorders, bowel diseases, malignancies, renal impairment. Celiac disease (CD) should be considered as one of the causes. In patients with CD, the frequency of pancreatic hyperenzymemia and possible pathophysiological mechanisms are not well studied. To date, several mechanisms explaining pancreatic hyperenzymemia in CD are reported. Malnutrition, disease bowel induced pancreatic dysfunction, autoimmune pancreatic inflammation, and macroenzymemia are the main ones. Herein, we report a patient with newly diagnosed CD, representing markedly elevated serum lipase level with normal amylase.

Published: March 2021

Introduction: Thyroid fine needle aspiration biopsy (FNAB) is performed under ultrasound guidance to make a diagnosis. According to EU-TIRADS (European Thyroid Imaging and Reporting Data System) category, the morphologic characteristics of the nodule is described. Histopathological results are classified according to the Bethesda system. In this single centre, retrospective study, to investigate which EU-TIRADS groups had no malignancy as a result of FNAB was aimed.

Methods: Ultrasonography findings and pathology reports of the patients whom FNAB was performed at the State Hospital between January 2016 and December 2018 were reviewed. 251 patients (201 female, 50 male) who were over 18 years of age (mean age 52.62 ± 12.29) were included.

Ultrasonographic findings were classified according to EU-TIRADS. Distribution of EU-TİRADS categories by Bethesda Classification was shown. Frequency tables, descriptive statistics, Kruskal-Wallis H test, and cross-tabulation were used. The analysis was performed using SPSS 25.0.

Ethics Committee approval and written informed consent were obtained.

Results: Of the 7 cases in Bethesda group V, which were ‘Suspicious for papillary carcinoma’, 42.9% were in ‘High-Risk Category’in EU-TIRADS and 57.1% were in ‘Intermediate-Risk Category’.

No benign cases in EU-TIRADS were in Bethesda IV, V and VI groups.

Conclusions: None of the benign cases in EU-TIRADS were found to be in the Bethesda IV-V-VI groups. By carrying out studies with larger number of cases, it can be investigated whether it will be considered safe to follow-up the cases in benign EU-TIRADS group without applying FNAB.
The evaluation of the relationship between antibody response and COVID-19 disease severity
Authors: GULLU Yusuf Taha , TUNA Tibel , GÜLLÜ KOCA Tuba
Published: March 2021

Background: World Health Organization (WHO) reported COVID-19 as a pandemic, on March 11th, 2020. The quick and accurate diagnosis is crucial to provide the appropriate treatment and isolation process. Immunity against COVID-19 is essential for disease control. There is scant information about antibody response and disease severity. In this study, we aimed to investigate the relationship between clinical severity and COVID antibody response.

Methods: Hospitalized PCR (n=10) and/or radiologically (n=31) proven 35 COVID-19 patients were included in the study. The blood samples were collected at least eight days after the onset of symptoms and studied by using the COVID-19 IgG/IgM Rapid Test. Patients were divided as mild (n= 14), severe (n=12) and critical (n=9) according to COVID-19 disease severity. The results were compared among the groups.

Results: A total of 35 COVID-19 patients’ (mean age: 54.65±16.51 years, Male/Female: 23/12) rapid test results were compared according to clinical severity. A significant correlation was observed between disease severity and IgG results in both PCR positive (p=0.007) and whole patients (p=0.026). The positive IgG ratio was significantly low in the mild patient group while it was higher in severe and critical patients.

Conclusions: Our study reveals that the greater antibody response occurs with the more serious COVID-19 disease. The application of the rapid test, in addition to PCR, may be used as a clue to foresee the clinical progression. These tests not only have an important role in diagnosis with PCR tests but also are associated with disease severity.
La crise financière au sein des écoles du Conseil des églises protestantes du Cameroun (CEPCA), 1987-2016
Authors: CLÉMENCE MAWA MIRAILLE
Published: March 2021

Fondée en 1969 des cendres de la Fédération des églises et missions évangéliques de l’Afrique Équatoriale Française, la FEMEC[1] a eu pour ambition de coordonner l’action spirituelle et sociale des églises protestantes présentes au Cameroun. Devenu Conseil des églises protestantes du Cameroun (CEPCA) en 2005, cet organisme œcuménique, dans son action sociale, s’intéresse à la scolarisation de la population en créant, entre autres, des écoles. Au cours des années 80, celles-ci se retrouvent de plus en plus dans l’incapacité d’assurer leurs différentes prestations. De cette situation, il est né une crise financière qui a affecté l’essor de l’enseignement privé protestant. L’assainissement de ce milieu éducatif et l’arrimage du CEPCA en général et de son département éducatif en particulier à la bonne gouvernance financière serait salutaire pour un rehaussement de l’image des écoles protestantes au Cameroun.

ComplexTrans – global land transportation system The best way ahead for railways and roads is coherent cooperation, not the competition
Authors: Hofman Jiri , Cermak Roman
Published: March 2021

The land-transportation cannot meet its demands anymore. Jammed highways and cities, dangerous emissions, omnipresent traffic accidents, delays, expensive railways.

Solutions are being sought to transfer a large part of passenger- and especially freight-traffic to (high-speed) rail and the efforts are shifting towards electromobility, car-sharing, 5G-connectivity, autonomous ride, MaaS-transport-coordination or Hyperloop-type solutions.

However, all these solutions have further problems and limitations.

Solutions are not sought where they really exist - in the mutual adaptation of the road and rail vehicles and their deep cooperation.

The ComplexTrans-project shows that simply adapting dimensions and functions of the road and rail vehicles can eliminate (or at least substantially reduce) all the problems of existing land transport. The main features of the ComplexTrans system are sufficient parking spaces, reduced traffic density inside and outside of the cities, electric-vehicles with unlimited range and cheaper than the standard cars, cheaper and affordable recharging of batteries, autonomous ride, self-financing rail-transport, transfer of intercity freight to rail, replacement of part of the continental air-transport and many others.

Aeromonas salmonicida is a fish pathogen that has resulted in significant losses to the aquaculture industry worldwide. In the winter of 2018/2019, a serious outbreak of A. salmonicida infection of grass carp (Ctenopharyngodon idella) occurred in China. Since C. idella do not feed at low water temperatures, antibiotics cannot be delivered orally, thus the use of disinfectants is the only viable option to control the disease in the winter months. Therefore, the aim of this study was to elucidate the inhibitory effects of different disinfectants against A. salmonicida at various temperatures and pH values. The microdilution method was used to determine the minimum inhibitory concentration (MIC) of five disinfectants against A. salmonicida at different temperatures. The results showed that A. salmonicida was highly adaptable to temperatures ranging from 8 to 35 °C and pH values from 5 to 9. Moreover, based on the results, benzalkonium bromide (BB) had the strongest inhibitory effect at every temperature. Since A. salmonicida has strong environment adaptability, BB should be chosen to control the disease at low temperatures.

Para una constelación espiritual constitutiva de Theodor W. Adorno
Authors: Larrauri Olguín Gibrán
Published: March 2021

Este trabajo pretende responder a una pregunta axial en el acercamiento al es- tudio de la obra de Adorno. ¿Cómo germinó en él el espíritu crítico? Entender esto, supone, desde mi perspectiva, conocer su vida más temprana, su infancia y juventud. La sensibilidad que subyace y de hecho motoriza el trabajo crítico de Adorno tiene como telón de fondo una infancia y una juventud invadidas, dañadas, por la convicción de que la verdad del drama humano deambula en lo negativo y sintomático, en lo disonante y lo no-idéntico. Se propone, entonces, hacer un recorrido por cómo fue que Adorno conoció personalidades que le ayu- darían a dar forma a su discurso, uno que combina la intensidad del afecto con el rigor del concepto. En esta historia, su encuentro con Alban Berg es capital.
Persuasive Gaming in Context
Authors: La Hera Teresa , Jansz Jeroen , Raessens Joost , Schouten Ben
Published: March 2021

The rapid developments in new communication technologies have facilitated the popularization of digital games, which has translated into an exponential growth of the game industry in recent decades. The ubiquitous presence of digital games has resulted in an expansion of the applications of these games from mere entertainment purposes to a great variety of serious purposes. In this edited volume, we narrow the scope of attention by focusing on what game theorist Ian Bogost has called 'persuasive games', that is, gaming practices that combine the dissemination of information with attempts to engage players in particular attitudes and behaviors.

This volume offers a multifaceted reflection on persuasive gaming, that is, on the process of these particular games being played by players. The purpose is to better understand when and how digital games can be used for persuasion by further exploring persuasive games and some other kinds of persuasive playful interaction as well. The book critically integrates what has been accomplished in separate research traditions to offer a multidisciplinary approach to understanding persuasive gaming that is closely linked to developments in the industry by including the exploration of relevant case studies.
Gambling and social gambling: An exploratory study of young people's perceptions and behaviour
Authors: Carran Margaret , Griffiths Mark
Published: March 2021

Background and aims: Gambling-type games that do not involve the spending of money (e.g., social and ‘demo’ [demonstration] gambling games, gambling-like activities within video games) have been accused in both the legal and psychological literature of increasing minors’ propensity towards prohibited forms of gambling thus prompting calls for gambling regulation to capture address such games and subject them to age restrictions. However, there is still a shortage of empirical data that considers how young people experience monetary and non-monetary gambling, and whether they are sufficiently aware of the differences. Methods: Data was collected from 23 qualitative focus groups carried out with 200 young people aged between 14 and 19 years old in schools based in London and Kent. As the study was exploratory in nature, thematic analysis was adopted in order to capture how pupils categorise, construct, and react to gambling-like activities in comparison to monetary forms of gambling without the constrains of a predetermined theoretical framework. Results: Despite many similarities, substantial differences between monetary and non-monetary forms of gambling were revealed in terms of pupils’ engagement, motivating factors, strengths, intensity, and associated emotions. Pupils made clear differentiation between non-monetary and monetary forms of gambling and no inherent transition of interest from one to the other was observed among participants. Only limited evidence emerged of ‘demo’ games being used as a practice ground for future gambling. Conclusion: For the present sample, non-monetary forms of gambling presented a different proposition to the real-money gambling with no inherent overlap between the two. For some the ‘softer’ form minimised the temptation to try other forms of gambling that they were not legally allowed to engage in, but ‘demo’ games may attract those who already want to gamble. Policy implications: Regulators must recognise and balance these two conflicting aspects.
