Medios de comunicación y confianza política en América Latina: análisis individual y contextual del rol de las noticias en la confianza en el gobierno y el Estado
Authors: Labarca Claudia , Valenzuela Sebastián , Bachmann Ingrid , Grassau Daniela
Published: December 2022

¿Cuál es la asociación entre exposición a noticias y confianza política en Latinoamérica? ¿Hay diferencias según la libertad del sistema de medios y los niveles de polarización política? Para responder estas preguntas, este estudio analiza 10 países latinoamericanos incluidos en la última Encuesta Mundial de Valores (2017-2020) (N = 11.769), así como los índices de intervención gubernamental en el sistema informativo y polarización del proyecto V-Dem. Los resultados estadísticos muestran que, en general, la exposición a noticias en plataformas sociales se relaciona negativamente con la confianza en instituciones del gobierno y el Estado. Sin embargo, el contexto hace una diferencia significativa: a mayor libertad de información y polarización, más negativa es esta relación. En cambio, el uso de los medios tradicionales se asocia positivamente con la confianza política, independientemente de los factores contextuales. Estos hallazgos confirman la importancia de considerar el contexto mediático micro y macro en el análisis sobre confianza en América Latina.
Hope as a Source of Grit
Authors: Rioux Catherine
Published: December 2022

Psychologists and philosophers have argued that the capacity for perseverance or “grit” depends both on willpower and on a kind of epistemic resilience. But can a form of hopefulness in one’s future success also constitute a source of grit? I argue that substantial practical hopefulness, as a hope to bring about a desired outcome through exercises of one’s agency, can serve as a distinctive ground for the capacity for perseverance. Gritty agents’ “practical hope” centrally involves an attention-fueled, risk-inclined weighting of two competing concerns over action: when facing the decision of whether to persevere, hopeful gritty agents prioritize the aim of choosing a course of action which might go very well over that of choosing a course of action which is very likely to go fairly well. By relying on the notion of a “risk-inclined attentional pattern” as a dimension of gritty agents’ practical hope, we can explain that form of hope’s contribution to their motivation and practical rationality, especially on a risk-weighted expected utility framework. The upshot is a more pluralistic view of the sources of grit.
Fallibility without Facts
Authors: Gamester Will
Published: December 2022

If, as expressivists maintain, the function of normative thought and talk is not to represent or describe the world, then how can normative judgements be correct or incorrect? In particular, how can I make sense of my own normative fallibility, the possibility that my own normative judgements might be mistaken? In this paper, I construct and defend a substantive but non-representational theory of normative (in)correctness for expressivists. Inspired by Blackburn’s (1998: 318) proposal that I make sense of my fallibility in terms of the possibility that my judgements might be unstable through improvement, my account is designed in the first instance to vindicate the expressivist’s conception of the nature of normative inquiry. I then defend the proposal from the charge that it leaves insufficient room for my own fallibility, and in particular from Egan’s (2007) argument that it implies a “smug” asymmetry between myself and others. Critical to the response is the appeal to indeterminacy in cases of fundamental normative disagreement between reasonable normative outlooks.
Social Inconsistency
Authors: Brouwer Thomas N. P. A.
Published: December 2022

Though the social world is real and objective, the way that social facts arise out of other facts is in an important way shaped by human thought, talk and behaviour. Building on recent work in social ontology, I describe a mechanism whereby this distinctive malleability of social facts, combined with the possibility of basic human error, makes it possible for a consistent physical reality to ground an inconsistent social reality. I explore various ways of resisting the prima facie case for social inconsistency. I conclude, however, that the prima facie case survives scrutiny, and draw out some of the ramifications.
Ugliness Is in the Gut of the Beholder
Authors: Doran Ryan P.
Published: December 2022

I offer the first sustained defence of the claim that ugliness is constituted by the disposition to disgust. I advance three main lines of argument in support of this thesis. First, ugliness and disgustingness tend to lie in the same kinds of things and properties (the argument from ostensions). Second, the thesis is better placed than all existing accounts to accommodate the following facts: ugliness is narrowly and systematically distributed in a heterogenous set of things, ugliness is sometimes enjoyed, and ugliness sits opposed to beauty across a neutral midpoint (the argument from proposed intensions). And third, ugliness and disgustingness function in the same way in both giving rise to representations of contamination (the argument from the law of contagion). In making these arguments, I show why prominent objections to the thesis do not succeed, cast light on some of the artistic functions of ugliness, and, in addition, demonstrate why a dispositional account of disgustingness is correct, and present a novel problem for warrant-based accounts of disgustingness (the ‘too many reasons’ problem).
Coupler sociologie et alimentation préventive pour une éducation à l’alimentation holistique
Authors: Lebredonchel Louis , Fardet Anthony
Published: December 2022

L’alimentation représente un enjeu majeur face à la croissante prévalence des maladies chroniques : soit en y contribuant, soit en les prévenant. Une éducation à l’alimentation pourrait permettre de lutter contre celles-ci, ainsi que contre les inégalités sociales de santé qui leurs sont liées. Bien qu’elle soit envisagée depuis une dizaine d’années par différents acteurs en France, l’éducation à l’alimentation semble n’en être qu’à ses débuts. Après avoir synthétisé ses enjeux et ses avancées, nous tenterons de contribuer à sa progression. A partir de réflexions théoriques et d’un travail empirique conduit dans cinq écoles primaires, nous proposons une approche pédagogique consistant en une « éducation à l’alimentation holistique ». Elle encourage les enfants à s’engager personnellement dans une réflexion et compréhension des liens entre l’alimentation, la santé et l’environnement, en y participant davantage en tant que véritables acteurs et qu'en tant que spectateurs passifs.

A social constructivist lens is used to explore how collaboration can facilitate the process. Some of the key concepts of social constructivism are outlined with a focus on the role of the teacher. Ways that social media are used in schools to support teaching and professional learning for teachers are presented. Discussion on ways social media was used during COVID-19 to connect students and teachers to support teaching and professional learning are investigated. The chapter concludes with possible future research directions.
Collaborative Learning With Mobile Technologies in Teacher Education
Authors: Obonyo Carolyne Nekesa
Published: December 2022

The increasing use of mobile technologies in K-12 schools has challenged teacher educators to consider how to best provide preservice teachers with the opportunity to integrate mobile technologies into their teaching and learning. In this chapter, the author aims to highlight how mobile technologies that support collaboration in both asynchronous and synchronous learning can enhance preservice teachers' teaching and learning experiences. Drawing from the literature, this chapter focuses on facilitating collaborative learning using mobile technologies in teacher preparation. The affordances of mobile technologies, which promote a social constructivist approach to learning, are discussed in detail. These affordances include the ability to enhance computer-mediated learning conversations, co-construction of knowledge, and social interactions using social media. This chapter also provides information on the barriers to technology adoption that hinder preservice teachers from integrating mobile technologies into teaching and learning.
Cooperative Learning in Virtual High School English Language Arts
Authors: Miller Janell A. , Young Carl A.
Published: December 2022

Cooperative learning (CL) has the potential to increase students' college and career readiness with benefits including higher student achievement, higher critical thinking, and greater psychological health (Johnson & Johnson, 1983, 1989; Kramarski & Mevarech, 2003; Natasi & Clements, 1991; Webb & Mastergeorge, 2003). This study explores student attitudes toward cooperative learning in two virtual high school English language arts (ELA) courses which occurred as a direct result of the COVID-19 pandemic. Employing action research methodology, the authors gained valuable insights about structuring cooperative learning in an online learning environment effectively. The study took place during the first eight weeks of two tenth grade ELA courses, one standard and one honors. Findings suggest many factors influence the implementation of effective cooperative learning within the virtual ELA classroom, including student attitudes and relationships, instructional time, class size, interdependence and group accountability, task completion, and modeling and practice.
A Conceptual Framework for Understanding How Early Career Literacy Teachers Curate a Lesson Plan in a Digital Age
Authors: Smith Melanie L.
Published: December 2022

Lesson planning is often identified as a challenge for early career teachers. Planning small group reading is particularly challenging for early career literacy teachers in the primary grades. They feel additional pressure to eradicate chronic reading failure and often struggle with knowing how to meet the diverse needs of their developing readers. Due to their lack of experience, they seek support from their social environment, including online sources, in today's digital age. This chapter aligns with Sawyer et al.'s (2020) critical curation theory, supporting the idea that ECLTs need support in determining quality when curating lessons from various sources. A conceptual framework is proposed to enhance knowledge of the curation process for ECLTs. Specifically, this conceptual framework will highlight possible sources ECLTs in the primary grades utilize in planning small guided reading group instruction. This chapter further highlights how ECLTs select sources from the Internet and use a research-based literacy framework to discern quality in their selection.
Impact of Integrated Reporting on Information Asymmetry: Evidence from Sri Lanka
Authors: Rajapaksha Samitha , Kehelwalatenna Sampath
Published: December 2022

Considering the dearth of empirical evidence on the impact of integrated reporting (IR) on information asymmetry in developing countries, this paper investigates the impact of IR on information asymmetry in Sri Lanka. A paired sample t-test and a panel regression analysis are employed to draw empirical evidence. Information asymmetry is proxied by earnings forecast error, earnings forecast dispersion, and cost of equity capital, whereas firms' IR level is measured using the IR framework. Findings indicate a significant reduction in information asymmetry upon adopting IR. Further, they reveal that the level of IR has a feeble but statistically significant negative impact on the cost of equity capital. Earnings forecast error and forecast dispersion do not indicate significant associations with IR levels. Given the substantial cross-country differences, this paper offers a better understanding of the impact of IR on information asymmetry from a developing country setting where the adoption of IR is voluntary.
An Index for Key Performance Indicators (KPIs): A Lens to Probe the Performance Drivers of Research in Commercial Agriculture
Authors: Abeysiriwardana Prabath Chaminda , Jayasinghe-Mudalige Udith K.
Published: December 2022

Research work carried out in any institution could be meaningfully administered, and the outputs generated rendered more rewarding for its key stakeholders, if a set of critical success factors (CSFs) are outlined ex-ante. When CSFs are neither clearly identified nor practised in a vital sector such as commercial agriculture, difficulties arise with timely monitoring and evaluation, and tallying the achievements with intended Sustainable Development Goals (SDGs) – particularly the goal of ‘zero hunger’. This article proposes a Key Performance Index (KPI index) that takes into account CSFs that would aid in evaluating the success of research linked with commercial agriculture development. How such an index is used to facilitate monitoring of scarce resource utilisation and internal processes of research institutes, and thereby support evidence-based decision-making to sustain a conducive research culture is explored with a special focus on underutilised performance drivers (e.g., societal development and environmental sustainability) in line with agriculture research.
Architectural Attributes for Social Sustainability a Framework for Analysing Housing Projects with Special Reference to the Maldives
Authors: Mohamed A. N. , Coorey S. B. A.
Published: December 2022

Social sustainability within the scope of the built environment is largely neglected despite its importance. The research aims to develop a theoretical framework highlighting the attributes of mass housing developments which are critical to social sustainability at a neighbourhood level. This is achieved by identifying the Social Sustainability Key Indicators (SSKI) which can be used to assess the overall social sustainability of four social housing projects in the Greater Male Region, Maldives. The residents of the housing developments were asked to rate their respective mass-housing for the nine SSKIs, the average of which gives the Perceived Social Sustainability Score (PSSS), as well as the level of satisfaction with seven critical architectural attributes which were identified from existing literature, and validated by professionals in the industry. The data from the respondents were then verified using One-way ANOVA, Pearson’s r Test of Correlation, and Multiple Linear Regression. The results indicate that a higher mix of land use, better quality housing, and well-planned infrastructure have a positive influence on the PSSS.
Strategies to Successfully Implement Industry 4.0 Concept for Predictive Maintenance in Facilities Management
Authors: Sivanuja T. , Sandanayake Y. G.
Published: December 2022

Maintenance management is an important function in Facilities Management (FM). Industries moved to preventive maintenance to counteract the inefficiencies of reactive maintenance, and further evolved into predictive maintenance (PdM). The demand for Industry 4.0-enabled PdM for FM has risen as a result of the industrial revolution and the dynamic nature of the FM industry. There are technology, investment, data, employees, integration, standardization, communication and security-related challenges in applying the Industry 4.0 concept for carrying out effective PdM under FM, which needs proper solutions. Thus, the study aimed at identifying strategies to successfully implement the Industry 4.0 concept for effective PdM in FM. The qualitative research approach was undertaken to accomplish the aim. A comprehensive literature review followed by 15 semi-structured interviews was carried out with experts in the maintenance sector who have Industry 4.0 knowledge. The data was collected from experts in Australia, Qatar, Dubai, Singapore, and Sri Lanka, and analyzed through code-based content analysis using NVivo 12. The research identified strategies to overcome technology, investment, data, employees, integration, standardization, communication and security-related challenges faced by facilities managers in applying the Industry 4.0 concept for carrying out PdM. Integrating Industry 4.0 along with PdM could be a game-changer for maintenance practitioners in the FM sector, allowing them to implement a real-time and failure-free maintenance approach that improves overall maintenance effectiveness and retains them ahead of the competition.
Impact of Colours in Classroom Interiors on Mental Health Undergraduates With Reference to Depression, Anxiety, and Stress Levels
Authors: Bandara K. M. S. , Hettiarachchi A. A.
Published: December 2022

Depression, anxiety, and stress symptoms are alarmingly increasing among university student populations and may have a major impact on achieving their academic and life goals. It is seen that in most cases the student’s academic performance, health, and quality of life is negatively impacted as a result. Research suggests that Architectural elements have an impact on mental distresses and individual wellbeing. This research attempted to address the above concern by focusing on the impact of colour, as an Architectural element, on psychiatric imbalances among Undergraduates with special consideration on depression, anxiety, and stress levels. The study was conducted with 36 participants from the Department of Architecture of the University of Moratuwa. Due to the COVID-19 pandemic's travel limitations, the study was conducted remotely through Zoom online conferencing platform and non-immersive virtual mode under three selected colour conditions (tints of green, blue, and red) with the aid of DASS-21 scale to evaluate stress, anxiety, and depression levels. Colour red was found to induce the most adverse impacts on stress, anxiety, and depression levels, whereas green indicated a comparatively low adverse impact. Blue had the slightest adverse impact on depression and anxiety with a slightly favourable impact on reducing stress. The findings of this study suggests that the incorporation of appropriate colours in design interventions could facilitate the creation of better classroom interiors in order to address depression, anxiety and stress related disorders of undergraduates. Further investigations in physical mode, incorporating a larger sample and other subject streams is recommended.
Integration of Formal and Informal Sector in Waste Management System in Sri Lankan Cities, Special Reference to Homagama
Authors: Perera L. H. R. , Ranasinghe T. K. G. P.
Published: December 2022

‘Solid waste management has been identified as a massive problem in especially developing countries, and there is no specific solution found for that. It is also a topic that gradually comes with a growing population, rapid urbanization, and fast development. There are two parties involved in waste management activities in the developing world, the formal sector and the informal sector. Both sectors play a specific role in the solid waste management process, but there is no official contact between these two sectors, which has an impact on the weekly waste management process. The purpose of this study is to investigate the formal and informal sectors' contributions to the waste management system, the importance of informal sector involvement in solid waste management, and to identify opportunities for integrating both sectors into the waste management process. Here, mass balance analysis is used to identify the waste flow within the boundary, and an integrated visualisation tool is used to identify possibilities for integrating formal and informal sectors in this Municipal solid waste management process. The result suggests the potential for integrating these two sectors in the municipal solid waste management system. It will provide mutual benefits for both sectors, public, health, and environment. Based on the findings, integration of both sectors will be a better solution for the solid waste management system in Sri Lankan cities.
The late-glacial and postglacial emergence and the deglaciation of the northernmost Labrador
Authors: Loken O
Published: December 2022

Detailed studies of the glacial morphology and raised shore features along the coastal part of the Torngat Mountains permit an appraisal of the late-glacial and postglacial emergence of the area in association with the final retreat of the last ice sheet. Three
specific strandlines are identified and found to tilt clown NNE; these are in turn truncated by a fourth, younger, horizontal strandline, about 15 m above present sea level. lsobases are drawn for the sea levels represented by two of the strandlines, and the map is the first attempt to show isobases
for Northern Canada from essentially contemporaneous shore features . Retreat and readvance phases of the outlet glaciers from the continental ice sheet to the west are identified, and the strandlines have provided a tool by which isolated moraines could be correlated. Finally, a late-glacial
chronology of the area is presented, which is, however, mainly a relative one. The only absolu te date is provided by a radiocarbon-dating of 9000 ± 200 years t for shells found at 29 m above present sea level. Theoretical and practical studies by Scandinavian workers in this specialized field
of physical geography are discussed in terms of their application to similar problems in Canada, and field and laboratory techniques that provide a basis for the present study are described.

Competitive and marketing aspects of the Labrador floater codfishery
Authors: Black W A
Published: December 2022

The development by Newfoundland of traditional markets for the Labrador heavy-salted codfish assured a steady market for this product at least prior to 1930. During the inter-war years, particularly during the 1930s, these markets underwent a major change which
resulted from two important and interrelated factors; first, economic measures and controls were used to hasten the growth of national economic self-sufficiency, and secondly, the growth of powerful and sustained foreign competition. The combined result was that heavy-salted codfish became a
residual product and an export casualty.
Snowcreep studies, Mount Seymour, B.C.: preliminary field investigations
Authors: Mathews W H , Mackay J R
Published: December 2022

Snowcreep is a slow, continuous, glacier-like downhill movement of the snowpack which takes place under shear stress sufficient to produce permanent deformation but too small to produce shear failure as in snowslides and avalanches. The main contribution of this
paper is the discussion of instrumentation developed for the measurement of snowcreep on Mount Seymour, B.C. during the period 1958-62. Methods are described, and preliminary results show that displacements of from 2 to 3.5 feet do occur in a single winter within the bottom 3 to 6 inches of the
snowpack on steeper slopes. I t is postulated that pressure of the downslope component of load is enough to push loose stones clown inclines, and presumably for this reason the bedrock slopes at the Mount Seymour test site are free of soil and boulders. The loads and amount of movement are also
considered adequate to account for the deformation of trees on the nearby timbered slope.

Examination of the carbonate content of drift in the area of Foxe Basin, N .W .T
Authors: Andrews J T , Sim V W
Published: December 2022

The Chittick apparatus has been used to examine the carbonate content of till from Melville Peninsula and the northern half of Baffin Island. Fifty-four samples have been examined. On Melville Island, east of the limestones, the fine-till fraction contains
between 44 and 71 percent carbonates; low values occur along the northern coast and south of Sarcpa Lake. On Baffin Island values are much lower, but it seems that they are slightly higher on the west coast than on the east coast. The high carbonate content across Melville Peninsula lends support to
the hypothesis of a westward movement from Foxe Basin, but the Baffin Island samples, with the exception of one from Piling Bay (26-per-cent carbonate content), possibly indicate that the eastward movement across the island was followed by a later westward flow toward Foxe
Basin.
Deglaciation and land emergence in northeastern Foxe Basin, N.W.T.
Authors: Ives J D
Published: December 2022

Between Longstaff Bluff and Steensby inlet, western Baffin Island, late-glacial marine submergence does not exceed 345 feet and decreases northward to 315 feet in Steensby inlet. Five collections of marine molluscs between 290 and 30 feet above sea level yielded
radiocarbon ages ranging from 6,725 ± 250 years to 2,050 ± 170 years. These ages allow construction of an uplift curve similar to others from different parts of Canada and Greenland. The 290-foot sample occurred close to the marine limit; its age (6,725 ± 250 years) is a good
approximation for that of maximum marine submergence, which is recent compared with that found in other parts of Canada. Geomorphological investigations revealed glacial outwash associated with morainic arcs, which are graded to various levels below the marine limit. That the evidence of submergence
in coastal valleys and inlets is often restricted to levels below 200 feet implies the presence of late-glacial, and possibly "postglacial," glacier ice. Baffin Island inland ice, therefore, penetrated a high-level Foxe Basin more recently, perhaps much more so, than 6,725 years ago. At least 30
feet of land uplift has occurred in the last 2,000 years, and it seems probable that uplift is taking place today.

Insomnia Is Not a Normal Part of Aging: The Challenges of Safely and Effectively Managing Insomnia in Older People
Authors: Espeso Natalie , Wick Jeannette Y.
Published: December 2022

Almost everyone has sleep problems from time to time, and often, simple nonpharmacologic interventions can improve sleep hygiene. When nonpharmacologic interventions fail, patients often request and may even require treatment with hypnotics. Insomnia is a heterogeneous disorder. Patients
with insomnia may have trouble falling asleep, staying asleep, or waking too early. Sleep disturbances are especially common in older people because of changes in sleep architecture. Though this population may benefit from hypnotics to improve sleep, these drugs increase the risk of polypharmacy,
drug interactions, and adverse drug effects, such as falls and cognitive impairment. Pharmacists must consider patient-specific factors to ensure older patients who require hypnotics receive an appropriate drug for an appropriate duration.
Влияние размеров классов сопряженности некоторых элементов
на структуру конечной группы

Пусть $G$ - конечная группа. Для каждого элемента $x\in G$
множество $\{x^g=g^{-1}xg: g\in G\}$ называется
классом сопряженности элемента $x\in G$ и обозначается
символом $x^G$. Размер класса сопряженности элемента $x\in G$
обозначается как $|x^G|$ или $|G:C_G(x)|$. Элемент $y$ группы $G$
называется примарным или бипримарным, если порядок элемента $y$
делится ровно на одно или два различных простых числа.
Для положительного целого числа $n$ и простого числа $p$,
если $e>0$ - целое число такое, что $p^e$ делит $n$, а $p^{e+1}$
не делит $n$, то $p^e$ называется $p$-частью числа $n$.
Пусть $p$ - простой делитель для $|G|$ такой, что $(p-1,|G|)=1$.
Доказано, что $G$ разрешимо и $p$-нильпотентно,
если размеры сопряженности всех нецентральных примарных и
бипримарных элементов в $G$ имеют одинаковую $p$-часть.
С другой стороны, предположим, что $N$ является
нормальной подгруппой групп $G$, и пишем
$\operatorname{cs}_G(N)=\{|x^G|:x\in N\}$.
Пусть $\operatorname{cs}_G(N)=\{1,n_1,n_2,…,n_t\}$,

$C_G(F(G))\leqslant F(G)$ и $[x,F(G)]$ является
нормальным подмножеством в $F(G)$ при всех $x\in N$ с $|x^G|=1$

Authors: Gök Veysel , Gümüş Gülsüm , Durmuş Habibe Selver , Ünal Ekrem , Gümüş Hakan , Karakükcü Musa , Kaçar Bayram Ayşe , Per Hüseyin
Published: December 2022

Objective: Opsoclonus myoclonus ataxia syndrome (OMAS) is a rare neurological disorder characterized by acute/subacute onset multi-directional chaotic eye movements, accompanied by myoclonus and cerebellar ataxia; as well as sleep disturbance, cognitive dysfunction, and behavioral disturbance can be observed.
Methods: We examined the information of eight patients (four females, four males) who applied to the hospital with OMAS between 2013 and 2020 from the medical records of the patients.
Results: The median age of onset of the initial symptoms was 17.5 months (8-30 months). The most common initial complaints were abnormal eye movement and gait unsteadiness, respectively. Paraneoplastic OMAS was observed in three patients (37.5%), whereas idiopathic and infection-related OMAS was detected in three, and two patients, respectively.
Conclusion: We emphasize that all symptoms of OMAS may not occur simultaneously, therefore comprehensive systemic investigations, and close observation should be made in patients with suspected OMAS.
Management of Foreign Body Ingestion in Children: A Single-center Experience
Authors: Yücel Aylin , Yaz Ömer
Published: December 2022

Objective: Foreign body (FB) ingestion is frequently encountered in childhood, and although the clinical results are often benign, it has high morbidity and mortality rates. Although guidelines for managing these children are available, there are still controversial aspects of the treatment recommendations. This study aimed to evaluate the treatment options for children who swallow FBs.
Methods: The study included 439 patients admitted with FB ingestion. Demographic and clinical features, type, size and localization of FB, treatment approach, and the timing of endoscopy were retrospectively scanned from hospital records.
Results: Most patients were male (58.3%) and 69.7% of the patients were aged <5 years. The most common symptom (42.3%) was nausea and vomiting and 82.5% of the patients were asymptomatic. The most common localization was the intestines (59.7%). While 84.1% of swallowed FBs came out with a spontaneous passage without complications, the endoscopic removal procedure was successful at the rate of 91.8%. The most frequently swallowed FB was coins (39.6%). Spontaneous elimination rates were higher for small coins and endoscopic removal rates were higher for large coins (p<0.001). The rate of emergency endoscopy was significantly higher in cases who swallowed a 2.6 cm coin (p<0.001). It was found that all sharp/pointed objects located in the intestine on admission came out spontaneously without complications. Sharp/pointed objects and button batteries located in areas accessible by esophagogastroduodenoscopy were more frequently removed using the endoscopic technique (p<0.001). In the cases with the ingestion of a single magnet or superabsorbent FB (giant growing toys), the FB came out with spontaneous passage without any adverse clinical outcome.
Conclusion: It can be suggested that this study of a large sample, showing the management of FBs without complications, will be of guidance in clarifying controversial aspects of the treatment.
Approaching a Newborn with Atypical Genitalia: Hints for Pediatricians
Authors: Güran Tülay
Published: December 2022

Infants born with genitals that do not appear typically male or female, are classified as having a difference/disorder of sex development (DSD). The current terminology and classification of DSD was established as suggested in the Chicago consensus statement in 2006. According to this consensus, patients with a DSD diagnosis are divided into three karyotype-based subgroups: 46,XY DSD; sex chromosome DSD, and 46,XX DSD. A newborn with DSD must be evaluated timely by a multi-disciplinary team including endocrinologist, psychologist, and urologist. The reason for this is two-fold: 1st to assign an appropriate sex of rearing to the infant based on the etiology of the condition and associated medical and psychosexual outcomes, and 2nd to detect any underlying life-threatening disorder if present. Neonates with ambiguous genitalia have various clinical presentations, etiologies, and outcomes. Furthermore, family adjustment and the degree of involvement of health professionals in psychosocial aspects of the condition affect health-related quality of life more than other congenital problems in DSD. For this reason, establishing correct communication with the patient and his/her family and providing appropriate information play a central role in DSD management and correct diagnosis and correct treatment. This review provides some clinical clues about the history, physical examination and laboratory and imaging characteristics of a newborn with DSD, which can allow for timely diagnosis, treatment and family counseling. We also emphasize some important points for an appropriate initial communication with the family of a patient with DSD.

Loanable funds, liquidity preference: structure, past and present
Authors: Correa Romar
Published: December 2022

We appraise the canonical RobertsonKeynes discussion from the structural axis of exogeneity/endogeneity of the interest rate. The interest rate is shown to be an exogenous variable. It is only with Keynes' contribution of liquidity preference and, specifically, the introduction of the liquidity preference of banks that no more than the possibility of endogenising the interest rate arises. Given the tenuousness of the resolution, we pose the ethical question: should the rate of interest be endogenised? On the other hand, Keynes' theorem that the rate of interest is a monetary variable is validated. Both money and the rate of interest are codetermined in a capitalist economy.
A review of David Colander, The Making of a European Economist, Cheltenham, UK, Edward Elgar, 2009, 190 pp.
Authors: Nicolae Mariana
Published: December 2022

David Colander's book on The Making of a European Economist is somehow a natural continuation of his by now classic studies on economics education in the US and of his book The Making of an Economist, Redux [1]. The book is fascinating to read not only by someone like me who is not really an economist, but has been close to the field and has been teaching students of economics for a long time, but mainly by policy makers both in the field of higher education and in other fields like business where the larger aspects of societal changes are more and more apparent.
Because I said so: the persistence of mainstream policy advice
Authors: Cline Nathaniel , Ford Kirsten , Vernengo Matías
Published: December 2022

The current global crisis has shown the limitations of the mainstream approach. We trace the origins of the limitations of the dominant neoclassical views to the capital debates and to the rise to dominance of intertemporal general equilibrium. The limited use of the Arrow-Debreu model, which became dominant after the capital debates, in terms of policymaking, is central to understand the persistence of policy guided by the aggregative model. We use the International Monetary Fund (IMF) as a case study of this perplexing continuity of policy advice. Given our survey, we conclude that even though the economy is in the midst of the worst capitalist crisis since the Great Depression, a significant paradigmatic shift in economics is extraordinarily unlikely.
Commentary on black political economy
Authors: Haynes Curtis
Published: December 2022

-

The task of this essay is to introduce a comprehensible study of the economic condition of a black sub-altern population in the United States. The framework is informed by the monumental contribution to the field of political economy as developed by Lloyd Hogan in his 1984, Principles of Black Political Economy. Specifically, Hogan presents political economy as: "The study of a human population under going the act of social reproduction, over a protracted period of time, under a set of rules promulgated and enforced by a political state, within a bounded geographical domain." (Hogan, p.12)
"The dangerous classes": Hugo Grotius and seventeenth-century piracy as a primitive anti-systemic movement
Authors: Wilson Eric
Published: December 2022

This essay discusses the historical and textual representations of piracy in the writings of Hugo Grotius, primarily De Indis/De iure praedae (1603-1608) and the Commentarius in Theses XI (c. 1600). Contrary to popular belief, Grotius, in stark contrast to Jean Bodin, was not an advocate of the constitutionally homogenous Nation-State. Rather, his central concept of divisible sovereignty, the lynchpin of the constitutional theory of his early writings, unambiguously presents us with the object of the heterogeneous State. In Grotian theory, the State may be "read" as a composite construction, with a residual degree of inalienable sovereignty accruing at each unit-level. Even if only unconsciously, Grotius describes a concurrent para-political subdivision of the state between institutional Government (the "magistrates") and civil society, one that constitutes an operational system of governance within the Nation-State. Like his contemporary Johannes Althusius, Grotius' theory allows for the emergence of a wholly "private," albeit lawful, mode of authority. This is most apparent in Grotius' treatment of the mercantile trading Company and its Privateering operations. The corporatist theory of sovereignty permits the Company's private agents of violence, the legally ambivalent Privateer/Pirate, to be invested with a requisite degree of sovereignty. The Grotian theory of divisible sovereignty, investing the seventeenth-century Pirate band with legal personality, serves as a vital historical precursor to the quasi-statist (trans-) national criminal cartels of the twenty-first century. The Grotian Pirate/Privateer/Just Avenger, therefore, is a "nomad": a liminal entity that simultaneously transverses both geographical and juro-political spaces, rendering him or herself in-determinable.
The Christian ethics of socio­economic development promoted by the Catholic Social Teaching
Authors: Bucciarelli Edgardo , Mattoscio Nicola , Persico Tony
Published: December 2022

This paper highlights the relationship between economic science and Christian moral in order to analyze the idea of socioeconomic development promoted by the Catholic Social Teaching (CST). In the first period leading up to the Second Vatican Council (1891-1962), from Pope Leo XIII to Pope John XXIII, the idea of development was connected both to technical and industrial progress, and to the universal values of justice, charity, and truth, which national communities were asked to follow. During the Conciliar period (1962-1979), the concept of development assumes a social and economic dimension, and so it becomes one of the main pillars of Catholic Social Teaching, which introduces the earliest definition of integral human development. Ultimately, in the post-Conciliar phase (1979-2009) including Benedict XVI's pontificate, the idea of integral human development reaches its maturity by incorporating the complexity of real-world economic interactions. Finally, this paper shows how the ethics bolstered by the Catholic Social Teaching is characterized by two distinct but complementary lines of thought: moral rules for both political action, and for socioeconomic issues.
Behavioural Procedural Models - a multipurpose mechanistic account
Authors: Ivarola Leonardo , Marqués Gustavo
Published: December 2022

In this paper we outline an epistemological defence of what we call Behavioural Procedural Models (BPMs), which represent the processes of individual decisions that lead to relevant economic patterns as psychologically (rather than rationally) driven. Their general structure, and the way in which they may be incorporated to a multipurpose view of models, where the representational and interventionist goals are combined, is shown. It is argued that BPMs may provide “mechanistic-based explanations” in the sense defended by Hedström and Ylikoski (2010), which involve invariant regularities in Woodward’s sense. Such mechanisms provide a causal sort of explanation of anomalous economic patterns, which allow for extra market intervention and manipulability in order to correct and improve some key individual decisions. This capability sets the basis for the so called libertarian paternalism (Sunstein and Thaler 2003).

The ‘desire for money:’ Aristotelian blind spot in the field of economics? A French heterodox point of view
Authors: Sobel Richard
Published: December 2022

If the field of economics has today become the archetype for determinism in the social sciences, it comes at the price of a form of objectivity founded on the complex process of the reduction and naturalization of a certain type of social relation, a process best described via the real approach or the ‘approach by value.’ A radical critique of this process requires the deconstruction of this dominant approach, characterized by the articulation of neoclassical theory and economic liberalism. It is only once the repression of the desire for money, a repression constitutive of false economic objectivity, has been denounced that the standard model can then be subject to such a critique. This will in turn open the possibility of an economic theory which is radically anti-naturalist.
