Published: January 2022

This paper attempted to explore the factors that contribute to halal food fraud and possible methods to address this problem. This paper uses a qualitative research approach as well as in-depth interviews with the two enforcement officials from JAIS and KPDNHEP. Based on the interviews, the researcher found that two key factors contributing to halal food fraud are lack of knowledge and halal as a marketing tool. After observing the factors, the researchers hypothesize solutions to the halal fraud epidemic. The study will help to improve the halal industry by solving all halal problems.

Results of computations with the use of improved modified Alekseevskii-Tate theory (IMATT) are compared to experimental data on high-velocity penetration of long rod projectiles into sand in the impact velocity range of V0=0.5-3.5 km/s. Projectiles were made of three different metals: M1 copper, WNZh tungsten heavy alloy and 30KhGSA steel. The value of hardening coefficient k in the linear dependence of the projectile material yield on pressure could be determined using IMATT and experimental data on dependence of differential penetration coefficient K on the penetration velocity. At penetration in regime of the hydrodynamic erosion of projectile, differential penetration coefficient K could be approximated just by dependence on the ratio of the impact velocity of penetration to the value of the critical velocity, above which the projectile deforms plastically during penetration. The values of the critical velocity may differ for specific projectile material properties as well as the density and the humidity of sand.
Температурный режим и механические напряжения в корпусированных фотоэлектрических преобразователях концентрированного солнечного излучения

In photovoltaic converters of concentrated sunlight, the thermal flow is directed from the photoactive region (p-n junction) to a heat-spreading basement through the substrate. The heat sink transfers the excess thermal to the environment by convection or cooled by a liquid carrier. Reducing the thickness of the substrate makes it possible to reduce the thermal resistance of the crystal and lower the operating temperature of the photoactive region. However, in this case, the mechanical stresses in it increase. This work discusses the balance between the mechanical strength of the sample and the decrease in its operating temperature.

Published: January 2022

BACKGROUND

Large-scale, polymerase chain reaction (PCR)-based SARS-CoV-2 testing is expensive, resource intensive, and time consuming. A self-collection approach is a probable alternative; however, its feasibility, cost, and ability to prevent infections need to be evaluated.

OBJECTIVE

This study aims to compare an innovative self-collection approach with a regular SARS-CoV-2 testing strategy in a large European industrial manufacturing site.

METHODS

The feasibility of a telemedicine-guided PCR-based self-collection approach was assessed for 150 employees (intervention group) and compared with a regular SARS-CoV-2 testing approach used for 143 employees (control group). Acceptance, ergonomics, and efficacy were evaluated using a software application. A simulation model was implemented to evaluate the effectiveness. An interactive R shiny app was created to enable customized simulations.

RESULTS

The test results were successfully communicated to and interpreted without uncertainty by 76% (114/150) and 76.9% (110/143) of the participants in the intervention and control groups, respectively (P=.96). The ratings for acceptability, ergonomics, and efficacy among intervention group participants were noninferior when compared to those among control group participants (acceptability: 71.6% vs 37.6%; ergonomics: 88.1% vs 74.5%; efficacy: 86.4% vs 77.5%). The self-collection approach was found to be less time consuming (23 min vs 38 min; P<.001). The simulation model indicated that both testing approaches reduce the risk of infection, and the self-collection approach tends to be slightly less effective owing to its lower sensitivity.

CONCLUSIONS

The self-collection approach for SARS-CoV-2 diagnosis was found to be technically feasible and well rated in terms of acceptance, ergonomics, and efficacy. The simulation model facilitates the evaluation of test effectiveness; nonetheless, considering context specificity, appropriate adaptation by companies is required.

Authors: Vats Vanshika , Nagori Aditya , Singh Pradeep , Dutt Raman , Bandhey Harsh , Wason Mahika , Lodha Rakesh , Sethi Tavpritesh
Published: January 2022

BACKGROUND

Shock is one of the major killers in Intensive Care Units and early interventions can potentially reverse it. In this study, we advance a non-contact thermal imaging modality for continuous monitoring and prediction of hemodynamic shock in advance.

OBJECTIVE

We aim to monitor and predict the advent of hemodynamic shock 6 hours in advance using an automated non-contact thermal imaging decision pipeline.

METHODS

Thermal Videos were captured in a Pediatric ICU-setting along with vitals time-series data. Deep-learning-based body-part segmentation models were trained to extract the Center-to-Peripheral temperature value difference from the videos. Extracted time-series data along with heart rate was finally analyzed using Long-Short Term Memory models to predict the shock status up to the next 6 hours.

RESULTS

103,936 frames from 406 non-contact thermal videos were recorded longitudinally upon 22 patients. Our models were able to predict the shock well till 6 hours of lead time using thermal information and achieved the best area under the receiver operating characteristics curve of 0.81±0.06 and area under the precision-recall curve of 0.78±0.05 at 5 hours, providing sufficient time to stabilize the patient.

CONCLUSIONS

Our approach leverages thermal imaging as a non-invasive and non-contact modality to continuously monitor hemodynamic shock, and thus, provides a reliable shock prediction using an automated decision pipeline that can provide better care and save lives.

Home-based dance exercise for adults with moderate Parkinson’s disease: Protocol with a pilot study for a non-randomized clinical trial using video-dances in a DVD format (Preprint)
Authors: Ferreira Manoela de Paula , da Silva Adriano Zanardi , Yamaguchi Bruna , Mathur Sunita , Melo Taina Ribas , Israel Vera Lucia
Published: January 2022

BACKGROUND

Many people with Parkinson’s disease (PD) have never received rehabilitation care due to lack of accessibility and transportation and high therapy costs for in-person rehabilitation. Home-based dance exercise is an innovative, low-cost therapy that may reduce accessibility barriers to exercise. Especially since the COVID-19 pandemic, home-exercise programs are a highly relevant, alternative approach for people with PD

OBJECTIVE

This clinical trial protocol aims to explore the effects of a Home-Based contemporary dance exercise program for people with moderate Parkinson’s Disease (PD), focusing on balance, functional mobility, quality of life (QOL), cognitive function, and depression.

METHODS

This protocol is for a non-randomized clinical trial for adults with moderate PD divided into control group (CG) and Experimental Group (EG). Participants from the EG will perform video-dances of the contemporary dance, delivered in a DVD format. The video-dances will be executed 16 weeks, three times per week, 30 minutes each day at home, with exercise intensity controlled by the BORG scale. Participants from the CG will not receive any new exercise therapy. As primary outcomes, the signs and symptoms of the PD assessed by the Unified Parkinson’s Disease Rating Scale – UPDRS II and III, Hoehn and Yahr for the PD severity, and health-related quality of life (HRQL), measured by the Parkinson’s Disease Questionnaire – PDQ-39) will be tested. Secondary outcomes include cognitive function by the Montreal Cognitive Assessment – MoCA, balance by the Mini-BESTest, functional mobility by the Timed “Up and Go” test – TUG and depression by the Geriatric Depression Scale – GDS. All outcomes will be assessed in an in-person evaluation by a blinded assessor before and after the 16 weeks of the program.

RESULTS

This protocol has a pilot study that included 10 participants (5 in each group). It was observed positive results favoring the EG over cognitive function (p = 0.034). In addition, HRQL, balance, and depression were improved after the pilot program in the EG, however, without significant difference.

CONCLUSIONS

This clinical trial has the potential to be a safe alternative exercise approach under COVID restrictions and travel-free therapy with effects on PD symptoms.

Published: January 2022

Proteases are enzymes used in industries such the production and processing of detergents, food, leather, and silk. The aim of this study was to isolate and identify protease‐producing bacteria from a sludge disposal site and from sediments. Soil samples were collected separately from the selected area. Samples weighing 1 g were serially diluted and spread onto skim milk agar. A total of 16 bacteria species were isolated from the study samples. Four bacterial isolates showed high proteolytic activity and were selected for enzymatic study based on their zone of proteolysis. The isolates were identified based on biochemical tests. The results indicated that the isolated bacteria were E. coli (99.69%), Pseudomonas putrefaciens (Shewanella putrefaciens) (91.61%), Bacillus carboniphilus (92.78%), and Lysinibacillus sphaericus (98.4%). The crude protease enzymes produced by these bacterial isolates showed promising results for application in dehairing and destaining as detergent additives. Bacillus carboniphilus showed the best level of activity and was selected as the most potent protease‐producing bacteria for both dehairing and destaining ability. Soils from sludge disposal sites and sediments from around tannery wastes could be good sources from which to isolate alkaline protease‐producing bacteria.

Scabies is a global disease with a high prevalence, causing morbidity and even mortality, especially in poor and developing countries. However, it is often misdiagnosed due to varied and unspecified lesions. The gold standard technique for diagnosis is a microscopic examination, which requires experienced experts in finding mites, mainly in ordinary scabies. CO1 and ITS2 genes have been widely used in molecular identification to detect Sarcoptes scabiei and its variants. This study aimed to determine and compare the sensitivity and specificity of CO1 and ITS2 S. scabiei genes to the microscopic examination of scabies skin scrapings. The skin scrapings of 52 subjects with scabies diagnosed by anamnesis, physical examination, and dermoscopic examination were examined under a microscope and analyzed by nested PCR. The diagnostic test result showed that the sensitivity of nested PCR of both CO1 and ITS2 genes to micro‐ scope examination was 100%. However, the specificity of both CO1 and ITS2 nested PCR was poor (24% and 0%). Hence, CO1 and ITS2 nested PCR could be more suitable for screening ordinary scabies in humans than the microscopic examination.

Streptomyces is one of mercury‐resistant bacteria which can convert Hg2+ into nontoxic Hg0 . This study aimed to identify mercury‐resistant Streptomyces present in the Cyperus rotundus rhizosphere from artisanal small‐scale gold mining (ASGM) area and clone merA gene to the cloning and expression vectors. Molecular identification was conducted using 16s rRNA gene with the maximum likelihood algorithms. Results revealed that the AS1 and AS2 strains were a group of Streptomyces ardesiacus and the BR28 strain was closed to Brevibacillus agri. The AS2 merA gene was cloned to pMD20 cloning vectors, pGEX‐5x‐1 and pET‐28c expression vectors. The transformation was successfully performed in BL21 and DH5α competent cells. The full length of the merA gene was confirmed to be 1,425 bp. This study is the first research on identifying mercury‐resistant Streptomyces and cloning the full‐length merA gene in Indonesia.
Sujeto y cotidiano en la era neoliberal: el caso de la educación chilena
Authors: Canales Cerón Manuel , Orellana Calderón Víctor Sebastián , Guajardo Mañán Fabián
Published: January 2022

Este artículo explora la subjetivación que experimentan los sujetos en sus elecciones y trayectorias educativas, en el contexto de una sociedad neoliberal avanzada como la chilena. Nos basamos en dos proyectos de investigación de carácter cualitativo, que han seguido las elecciones educativas de padres sobre sus hijos y de jóvenes sobre su futuro postsecundario. Con la transformación estructural que impulsa el giro neoliberal, surgen nuevos sectores populares en un contexto de amplia mercantilización de las relaciones sociales, que alcanza a la educación y la configura bajo la lógica del mercado. En tal dinámica, las elecciones educativas y su inscripción subjetiva —lo que hemos denominado mercadeo educativo— permiten advertir un panorama nuevo de estratificación social. Las elecciones educacionales, aparentemente autónomas, van marcando la estratificación real y nueva de la sociedad. Este mercadeo educativo se proyecta como nexo entre estructura y subjetividad, formando a los sujetos en una alta individualización de su reproducción social.
El partidismo racional en la Ciudad de México: 2012 vs. 2018
Authors: Sánchez y Sánchez Carlos Luis
Published: January 2022

En este artículo se analizan los patrones de cambio y estabilidad del partidismo en la Ciudad de México en las elecciones para jefe de Gobierno de 2012 y de 2018. A partir de la información recopilada en encuestas de salida realizadas a los votantes, el análisis se enfoca en cuatro fenómenos relacionados con la identidad partidista en la Ciudad de México en un periodo de seis años: primero, la estabilidad del partidismo a nivel agregado de 2012 a 2018; segundo, el realineamiento electoral que se tradujo en la emergencia y consolidación de la identificación partidista con el Movimiento de Regeneración Nacional (Morena); tercero, un fortalecimiento del voto partidista, tal y como lo refleja el debilitamiento del voto cruzado y del voto dividido de una elección a otra, lo cual indica que la identificación partidista se constituyó en un importante predictor del voto en la elección de jefe de Gobierno en la Ciudad de México en 2018; finalmente —con base en un análisis multivariado que permitió explicar en lo general los determinantes del partidismo— se pudo establecer que las características más significativas asociadas con el perredismo son ahora constitutivas de la identificación política con Morena, lo cual señala que pervive un modelo de formación de las identidades partidistas que en este trabajo denominamos partidismo racional.

Dilemas constitucionales vigentes en la implementación de los protocolos para atender la violencia de género en las universidades
Authors: Ortiz Ortega Adriana , Góngora Janette , Aguilar Barroso Claudia
Published: January 2022

Este artículo explora la forma desigual en que se juzga con perspectiva de género —elemento indisoluble de la aplicación normativa precisa de leyes y tratados internacionales a favor de la vida libre de violencia para las mujeres— en los campos universitarios. Se advierte que ocurre un proceso paradójico: por un lado, una creciente emisión de protocolos; por otra parte, persiste una baja asociación entre los bloques de convencionalidad, de constitucionalidad vigentes y las medidas propuestas desde el Poder Judicial de la Federación con las disposiciones establecidas en dichos protocolos, esto con base en el estudio de 56 protocolos de Instituciones de Educación Superior (IES) —ya sean privadas o públicas—. Este artículo documenta cómo las instituciones de educación superior pueden mejorar el tratamiento de la violencia de género en la medida de comprender el alcance del control de convencionalidad para poder cumplir con la reforma a la Ley de Educación Superior. De acuerdo con esta reforma —emitida en 2021—, las instituciones de educación superior, y con el apoyo de las autoridades respectivas, promoverán las medidas necesarias para la prevención y atención de todos los tipos y modalidades de violencia, en específico la de género, así como para la protección del bienestar físico, mental y social de sus estudiantes y del personal que labore en ellas.

Trabajo infantil y rendimiento escolar en México
Authors: Santillán Hernández Alma Sofía , Vargas Sánchez Juan Roberto
Published: January 2022

En el presente texto se analiza la relación entre trabajo infantil y rendimiento escolar en matemáticas en estudiantes mexicanos de primaria y secundaria a nivel nacional. Se empleó el método de variables instrumentales (VI), ya que la modelación conjunta del trabajo infantil y el rendimiento escolar pueden generar endogeneidad. Incluso, controlando por la pobrezadel hogar, la modalidad educativa y el grado de marginación de la comunidad, los resultados muestran que el efecto del trabajo infantil sobre el rendimiento escolar es negativo y no hay diferencia entre trabajar en un negocio familiar o no en ambos niveles escolares. Distinguiendo por género, existe evidencia de que el resultado es más pronunciado en niñas que en niños.

This paper aims to discuss rights of non-Muslim citizens in Indonesia at government refers to the conception of the state of Dien wa Ni'mah. The main argument in this paper that the concept of Dien wa Ni'mah prioritize law as an important pillar can accommodate pluralism and contextual with the system of the Unitary State of the Republic Indonesia based on Pancasila. The research method used was a historical study, based on a comprehensive literature review from various sources in books and journals about the concept of Dien wa Ni'mah. The results of this study explain that Dien wa Ni'mah is a concept of the manifestation of Islam as a religious teaching that is Rahmatan Li al-Alamin and build human life through law as the main universal pillar, not only as the theological framework and spiritual principles of mankind, also in the life of society, nation and religion. So this concept accommodates the rights of non-Muslims in government by considering pluralism and democracy. Thus making the concept of Dien wa Ni'mah as the nation's perspective to the Civil Society will have an impact on the participation of all parties.
Foucauldian Biopolitics, Irregular Immigrants and COVID-19 in Malaysia
Authors: Cingir Omer Faruk , Subramaniam Thirunaukarasu
Published: January 2022

This paper addresses issues related to irregular immigrants during the COVID-19 pandemic, with the aim of providing a better understanding of the migration process in Malaysia. This article uses Foucauldian biopolitics as a theoretical framework to explain state practices on immigrant bodies. Firstly, it provides a general picture of irregular immigration in Southeast Asia and Malaysia; secondly, it summarises the effects of the pandemic; and lastly it provides an overall outlook of irregular immigrants and the practices they were exposed to at this time. This study adopts exploratory and explanatory qualitative research design and data collection techniques such as document analysis of non-governmental reports on immigrants, official statistics, declarations and articles produced by third party organisations and interviews with experts. This paper then adopts a post-structuralist perspective within an interpretative paradigm to comprehend the main problems, social arrangements and rationality of institutional dynamics of the management of irregular immigrants. The main findings show that increasing human rights violations of irregular migrants generate from a biopolitical mentality.
The Impact of Monetary Policy on Bank Profitability and the Moderating Role of Funding Patterns in Vietnam
Authors: Dang Van Dan
Published: January 2022

The study investigates the effect of monetary policy on bank profitability while also taking into account the moderating role of bank funding patterns. Uniquely, the study focuses on disaggregate components of bank profits in an environment containing various monetary policy tools. Using a dataset of commercial banks in Vietnam, the results show that monetary policy drives bank profitability asymmetrically. Concretely, interest rates (i.e., lending rates and policy rates) exert positive effects on net interest income, but negative impacts on non-interest income. For quantitative-based policy tools, including the central bank’s security purchases and foreign exchange reserves, monetary policy is positively correlated with non-interest income but negatively associated with net interest income. The reaction of banks’ net interest income to monetary policy adjustments is translated into overall bank profits. Further analysis indicates that the monetary policy/bank profitability nexus across different proxies is less pronounced at banks with more diversified funding patterns. This finding sheds light on prior arguments attributing financially weaker banks’ greater sensitivity in facing monetary shocks to the limited alternative funding.

Is there a trade convergence between South East European and Central European economies
Authors: Nikolic Goran , Nikolic Ivan
Published: January 2022

Given the importance of trade performance to overall economic fundamentals,
the question arises as to the extent that South East European Countries
(SEEC) have successfully followed the successful transition path of Central
and Eastern European Countries (CEEC). To address this issue, we use
similarity indicators to calculate possible convergence between the export
structures of SEEC and CEEC from 2007-2008 to 2018-2019. We then compute the
value of the similarity coefficients of SEEC and CEEC export structures and
compare them with EU import structures, and intra-industry trade for both
SEEC and CEEC. Next, we calculate the qualitative changes of both SEEC and
CEEC merchandise trade through the tendency of technology-intensive
products. The results of these two groups are compared to determine whether
SEEC trade performance is converging to that of the CEEC. The results show
structural improvements and an above-average increase in SEEC trade since
2007. However, given the simultaneous, moderate qualitative trade progress
in the CEEC, the convergence between these two groups is insufficient to
close the gap in the foreseeable future.
Revisiting the debt-growth nexus: Evidence from India
Authors: Saini Pratibha , Muniyoor Krishna
Published: January 2022

The main purpose of this study is to examine the debt-growth nexus in India
over the period 1984-2019 using Bayer-Hanck and Autoregressive Distributed
Lag (ARDL) cointegration techniques. The findings of both techniques suggest
the existence of a negative relationship between public debt and economic
growth in the long run. The results also confirm the significant negative
relationship between foreign exchange reserves and economic growth.
Interestingly, the test results confirm the unidirectional causality running
from public debt to economic growth in the case of India. From a policy
perspective, reducing public debt is imperative to achieve long-term
sustainable growth. Efforts should be made to circumvent the burden of
burgeoning interest liabilities by generating a primary surplus, which will
facilitate debt servicing and timely repayment of debt.
Bracket transfer accuracy with two different three-dimensional printed transfer trays vs silicone transfer trays
Authors: Hoffmann Lea , Sabbagh Hisham , Wichelhaus Andera , Kessler Andreas
Published: January 2022

Objectives

To compare the transfer accuracy of two different three-dimensional printed trays (Dreve FotoDent ITB [Dreve Dentamid, Unna, Germany] and NextDent Ortho ITB [NextDent, Soesterberg, the Netherlands]) to polyvinyl siloxane (PVS) trays for indirect bonding.

Materials and Methods

A total of 10 dental models were constructed for each investigated material. Virtual bracket placement was performed on a scanned dental model using OnyxCeph (OnyxCeph 3D Lab, Chemnitz, Germany). Three-dimensional printed transfer trays using a digital light processing system three-dimensional printer and silicone transfer trays were produced. Bracket positions were scanned after the indirect bonding procedure. Linear and angular transfer errors were measured. Significant differences between mean transfer errors and frequency of clinically acceptable errors (<0.25 mm/1°) were analyzed using the Kruskal–Wallis and χ2 tests, respectively.

Results

All trays showed comparable accuracy of bracket placement. NextDent exhibited a significantly higher frequency of rotational error within the limit of 1° (P = .01) compared with the PVS tray. Although PVS showed significant differences between the tooth groups in all linear dimensions, Dreve exhibited a significant difference in the buccolingual direction only. All groups showed a similar distribution of directional bias.

Conclusions

Three-dimensional printed trays achieved comparable results with the PVS trays in terms of bracket positioning accuracy. NextDent appears to be inferior compared with PVS regarding the frequency of clinically acceptable errors, whereas Dreve was found to be equal. The influence of tooth groups on the accuracy of bracket positioning may be reduced by using an appropriate three-dimensional printed transfer tray (Dreve).
Machine learning classifiers do not improve prediction of hospitalization > 2 days after fast-track hip and knee arthroplasty compared with a classical statistical risk model
Authors: Johannesdottir Katrin B , Kehlet Henrik , Petersen Pelle B , Aasvang Eske K , Sørensen Helge B D , Jørgensen Christoffer C
Published: January 2022

Background and purpose — Prediction of postoperative outcomes and length of hospital stay (LOS) of patients is vital for allocation of healthcare resources. We investigated the performance of prediction models based on machinelearning algorithms compared with a previous risk stratification model using traditional multiple logistic regression, for predicting the risk of a LOS of > 2 days after fast-track total hip and knee replacement.
Patients and methods — 3 different machine learning classifiers were trained on data from the Lundbeck Centre for Fast-track Hip and Knee Replacement Database (LCDB) collected from 9,512 patients between 2016 and 2017. The chosen classifiers were a random forest classifier (RF), a support vector machine classifier with a polynomial kernel (SVM), and a multinomial Naïve-Bayes classifier (NB).
Results — Comparing performance measures of the classifiers with the traditional model revealed that all the models had a similar performance in terms of F1 score, accuracy, sensitivity, specificity, area under the receiver operating curve (AUC), and area under the precision-recall curve (AUPRC). A feature importance analysis of the RF classifier found hospital, age, use of walking aid, living alone, and joint operated on to be the most relevant input features. None of the classifiers reached a clinically relevant performance with the input data from the LCDB.
Interpretation — Despite the promising prospects of machine-learning practices for disease and risk prediction, none of the machine learning models tested outperformed the traditional multiple regression model in predicting which patients in this cohort had a LOS > 2 days.
Förutsättningar för multimodalt meningsskapande i svenskämnets kursplaner på grundlärarutbildningen
Authors: Godhe Anna-Lena , Edström Ann-Mari
Published: January 2022

Med utgångspunkt i en analys av kursplaner för svenskämnet inom grundlärarprogrammet vid fyra svenska lärosäten syftar denna artikel till att belysa skillnader i förhållningssätt till multimodalt meningsskapande samt hur dessa ramar in studenternas möjligheter till multimodalt meningsskapande. Analysen visar på tre huvuddrag i förhållningssättet till multimodalitet: som digitalitet, som stöd för annat lärande och som kunskapande i sin egen rätt. Spänningar mellan dessa tre förhållningssätt utforskas vidare och visar att processen fokuseras då multimodalitet ses som kunskapande i sin egen rätt medan representationen, i form av en produkt, blir det som hamnar i fokus utifrån de andra förhållningssätten. Ett holistiskt synsätt på kvalitativa aspekter av multimodalitet möjliggörs när meningsskapande processen och relationella aspekter fokuseras.

This essay provokes who the “experts” are in discussions about education: why not the students who are most impacted by it? At the Centre for Environment and Development Studies (CEMUS), a joint centre between Uppsala University and Swedish University of Agricultural Sciences, students are hired as Course Coordinators (CCs) to develop and facilitate freestanding university courses. This paper is an outcome of a collaborative reflection exercise in the form of a written dialogue between students, CCs, and a guest lecturer of a CEMUS course “Reimagining Education”. This course focused on approaching learning and education on a meta-level where students and their experience become the subject of collaborative learning. By comparing the experience from this course with other courses at CEMUS and beyond, we discuss whether and how CEMUS challenges traditional pedagogies based on teacher-student hierarchies. Both the capacity for CCs to influence the content and pedagogical arrangements as well as the opportunities for non-CC students to take responsibility in steering class discussions were highlighted as empowering experiences. We reflect upon how this and the use of arts-based pedagogies can lead to fostering community and how it motivates students to collectively engage in their personal learning experiences beyond curriculum goals.
Patrons, Landscape, and Potlatch: Early Medieval Linear Earthworks in Britain and Bulgaria
Authors: Squatriti Paolo
Published: January 2022

Often seen as exceptional monuments, comparative analyses of linear earthworks are rare. Exploring Offa’s Dyke (Wales and England) and the Erkesiya (Bulgaria) as comparable expressions of authority in the early medieval landscape. This article is a revised and updated republication of an early study (Squatriti 2001), arguing that  both linear monuments represent strategies to not only reflect, but actively create, royal power.
Exploring Linear Earthworks across Time and Space – Introducing the ‘Monumentality and Landscape: Linear Earthworks in Britain’ Project

Linear earthworks of a monumental character are an enigmatic part of the British landscape. Research in Britain suggests that such features range in date from the early 1st millennium BC to the Early Middle Ages. While the  roles of these monuments in past societies cannot be understated, they remain a relatively under-researched phenomenon. This article introduces the Leverhulme Trust-funded ‘Monumentality and Landscape: Linear Earthworks in Britain’ project, which aims to provide a comparative study of linear earthworks focusing on those dating to the Iron Age and early medieval period. This contribution reviews our approach and shares preliminary results from the project’s first year, identifying wider implications for the study of linear earthworks.

New observations concerning the Mercian/Welsh frontier, principally on Offa’s Dyke (but also on Wat’s Dyke and in the Vale of Clwyd), were  made each winter between 2016/17 and 2019/20 by the lead author with, at one time or another, each of the collaborators in this article. The prime focus here is upon Offa’s Dyke in west Gloucestershire and in Flintshire, in both of which areas fieldwork is adding incrementally to our stock of knowledge about the extent and nature of the monument. However, observations elsewhere on its course, such as in west-central Herefordshire, at Hem (Montgomeryshire), and near Trefonen (Shropshire) are also noted in brief descriptive sections. The identification of ‘new’ lengths of Offa’s Dyke in Tutshill (near Chepstow) and between Lower Redbrook and Lower Lydbrook south-east of Monmouth indicates that the linear earthwork was built as a near-continuous or continuous monument in these southerly areas. Meanwhile, the discovery of lengths of linear earthwork in Flintshire that could have formed part of a continuous course reaching the sea near Gronant east of Prestatyn has also raised important questions about the relationship of Wat’s Dyke to Offa’s Dyke.

O Historiógrafo e o Analista do Discurso costumam deparar-se com diversas situações da linguagem em uso no dia a dia, o que lhes propicia uma produção de corpus para análise e pesquisa. Nessa perspectiva, é importante destacar que os textos literários pressupõem um trabalho de equilíbrio entre os conceitos teóricos e uma visão ligada ao contexto histórico e social, no caso deste artigo, na obra literária de José Lins do Rego, Menino do Engenho. Nessa esteira de pensamento, tem-se por objetivo identificar, na produção do discurso dominante do coronel, personagem central da história, as marcas linguísticas que lhe conferem autoridade, a partir do contexto histórico brasileiro do século XX. Sendo assim, a pesquisa demanda reflexão acerca da situação do contexto histórico e social no qual o texto foi produzido.
