Ukraine is here, the maps stay the same. On the ethics of framing an analysis.
Authors: Denis Claude
Published: October 2022

With Russia’s invasion of Ukraine, the world in which New Area Studies (NAS) were born has shifted, and this leaves us with a number of questions on how to move on. In this post-2/24 world, we are back to the past of raw military power, colonial conquest and destabilized international borders. And because the invasion is, itself, explicitly dealing with Ukraine and its borderlands as constructs of history and of politics – as illegitimate constructs, in the Putinian telling – it presents an ethical challenge for constructivist, NAS scholars. I am proposing a two-part ethical and political reflection on how to think about Russia’s invasion of Ukraine – and, more to the point, how to think about areas and borders in view of the war.In different circumstances, highlighting the historical constructedness of Ukraine’s (and therefore Russia’s) borders would make sense, while always carrying risks of “recuperation” by Russian revanchists. Now, this risk is heightened sharply and the question of how to be a scholar in a time of war is urgent. Analysis of the situation needs to be anchored first and last in a recognition of the profound wrong that is being perpetrated by Russia against Ukraine, and in an affirmation of the Ukrainian people’s existence and right to exist. The first part of the ethical reflection, then, calls for resisting the use of history as justification for political projects. The second part of the ethical reflection resists a different dimension of the urge to step back and contextualize, especially in left-leaning academia: the critique of American imperialism and of NATO’s very existence as its instrument. But putting one’s critical and political energies, now, in fighting NATO’s expansion and support of Ukraine cannot but bolster Russia. Whatever NATO’s misdeeds were toward Russia in the past thirty years, there can be no equivalence with the death and destruction that Russia is raining on Ukraine since 2/24 – and recognition of this fundamental imbalance must inform our practices, as citizens and as scholars.
TD 2784 - O Estudante de hoje financiado pelo profissional do amanhã : proposta de um sistema nacional de financiamento estudantil com pagamentos vinculados à renda futura – funcionamento e fonte de recursos
Authors: Nascimento Paulo Meyer
Published: October 2022

Neste estudo, propõe-se um sistema público-privado de assistência financeira para estudantes de educação superior (ES) e de educação profissional e tecnológica (EPT). Funciona tanto como um seguro (só paga de volta se tiver renda compatível) quanto como um sistema de repartição às avessas (estudantes do passado financiam estudantes do presente). Estudantes teriam a possibilidade de contratar financiamentos oferecidos por instituições públicas e privadas nos parâmetros definidos em lei e por instrumentos regulatórios, sem necessariamente atrelar o financiamento contratado ao pagamento de encargos educacionais de qualquer natureza. O funcionamento do sistema pressupõe a introdução de uma nova contribuição no Sistema Tributário Nacional (STN). O novo tributo não aumenta a carga tributária, mas é central à proposta por ser a forma de viabilizar que a Receita Federal recolha pagamentos proporcionais à renda das pessoas financiadas. O novo tributo alcançaria ainda estudantes de cursos gratuitos ou com matrícula em cursos pagos, estes financiados pelo Estado. Assim, financia-se a expansão do segmento público e reduz-se o custo fiscal da assistência a estudantes do segmento privado. Ademais, o sistema proposto busca remover assimetrias que atravancam o mercado privado de crédito educativo e de investimento em pessoas.
TD 2788 - A inserção dos BRICS na África austral
Authors: Assis Caroline Chagas de
Published: October 2022

A África teve, durante o século XXI, sua importância estratégica renovada devido à importância crescente de novos atores no sistema internacional que buscavam mercados para vender seus produtos e parcerias estratégicas. Entre esses atores estão Brasil, Rússia, Índia e China, formando o bloco econômico BRICs. Este estudo – que faz parte do projeto A Agenda Externa do Brasil para a África: Avaliações e Propostas, promovido pelo Instituto de Pesquisa Econômica Aplicada (Ipea) e desenvolvido durante 2020 – buscou entender como os BRICs se inseriram historicamente na região austral da África e como se estabeleceram comercialmente na região, demonstrando suas principais estratégias e seus mecanismos de aproximação. Ao longo do trabalho ficou evidente que apesar de serem considerados novos atores no continente africano, os BRICs têm um histórico importante de inserção na região austral da África, inclusive considerando-a estratégica para seus planos de projeção internacional. Esses atores, apesar de sua união no grupo dos BRICS, apresentam estratégias de inserção diferentes, o que garante nichos de mercado que os tornam complementares em alguns setores, porém concorrentes em outros.
TD 2789 - Catch-up Tecnológico e Superação da Armadilha da Renda Média: O Caso da China no Setor de Semicondutores
Authors: Moreira Uallace
Published: October 2022

Este estudo analisa as estratégicas de catching-up e leapfrogging implementadas na China, como mecanismo de superar a armadilha da renda média. Utiliza-se o arcabouço teórico e metodológico do sistema setorial de inovação (SSI – em inglês, sectoral systems of innovation) e estratégia de catch-up de acordo com o ciclo de vida tecnológico do produto, como estratégia viável de inserir-se em fronteiras tecnológicas mais avançadas, assim como romper com os limites do desenvolvimento. Nesse sentido, analisou-se o setor de semicondutores como estudo de caso, principalmente por ser um setor que está na fronteira tecnológica e se tornou mais relevante ainda com a ascensão e a expansão do que se convencionou chamar de Indústria 4.0. O papel estratégico que o setor de semicondutores tem ganhado na economia internacional tornou-se também alvo de disputas tecnológicas entre China e Estados Unidos. Analisando-se um conjunto de indicadores e a evolução das políticas implementadas na China para promover o setor de semicondutores, afirma-se que há elementos que apontam para o fato de que, até mesmo diante das suas limitações, o país tem logrado avanços consideráveis na construção da indústria de semicondutores, o que permite afirmar que o futuro desse setor na China é promissor.
Podas y ciclos de renovación: obtenga una caficultura joven y productiva
Authors: Rendón José Raúl
Published: October 2022

El café es un cultivo perenne que requiere de renovaciones para mantener altos niveles de producción y facilitar el manejo agronómico, como alternativas de renovación, en la caficultura colombiana se conocen prácticas de poda y zoqueo que promueven la formación de brotes o chupones nuevos en el tallo. La duración del ciclo de producción a su vez se relaciona con las características de suelo, clima, topografía, variedad y manejo del cultivo. Una correcta planificación de la renovación de cafetales está determinada por el momento en que termina la cosecha; para regiones de cosecha principal en el primer semestre del año las renovaciones se hacen en el segundo semestre; para regiones de cosecha principal en el segundo semestre las renovaciones se hacen en el primero y en zonas donde la cosecha se distribuye igual en los dos semestres, se recomienda renovar en el semestre con menor intensidad de lluvias. Para estabilizar la producción cuando se tienen cafetales envejecidos se ha recomendado la división del área cultivada en quintas partes con el propósito de mantener como mínimo un 80% de los árboles en producción y un 20% renovado, es a través de estos sistemas de manejo y la planificación de los ciclos de producción, que los productores pueden mantener una caficultura joven y productiva en el tiempo.
Germoplasma “silvestre” de Coffea arabica L. y su rol en el mejoramiento genético
Authors: Arias Juan Carlos
Published: October 2022

Disponer de variabilidad genética amplia y suficiente, abre la oportunidad al fitomejorador para dar solución a problemáticas actuales y potenciales de una especie determinada. En el caso de Coffea arabica L., la reducida base genética que dio origen a su cultivo, que la hacía especialmente susceptible a plagas y enfermedades, sumado a la destrucción progresiva de su hábitat en Etiopía, centro de origen y diversidad, motivó en la década de los 60’s la realización de prospecciones para la recolección de sus recursos genéticos. La distribución de los genotipos recolectados a diferentes centros de investigación marcó un hito para los programas de fitomejoramiento, debido a que enriquecieron significativamente la variabilidad genética disponible. No obstante, a pesar de su potencial, su uso ha sido bajo y dirigido hacia la resistencia a la roya del cafeto. Por su origen, el germoplasma etíope de café brinda una gran posibilidad para el mejoramiento de otras características agronómicas de interés. Para ello, los procesos de evaluación y caracterización son claves, al permitir identificar las propiedades de los genotipos, además de incrementar el valor del recurso genéticio conservado. El objetivo de este seminario es proporcionar información relacionada al germoplasma de este origen, utilización, resultados de caracterización y evaluación, y perspectivas para su uso en en el mejoramiento genético del café en Colombia.
Avances en la evaluación de poblaciones de café con menor número de estados de la broca del café (Hypothenemus hampei, Ferrari)
Authors: Molina Diana María
Published: October 2022

Inicialmente el mejoramiento genético de café se enfocó en la selección de variedades de alto rendimiento y buena calidad; sin embargo, la aparición y posterior propagación de enfermedades como la roya del cafeto (Hemileia vastatrix Berk. y Br) favorecieron el desarrollo de variedades resistentes. En el caso de insectos plaga como la broca del café (Hypothenemus hampei, F), los primeros estudios de búsqueda de fuentes de resistencia evidenciaron que todas las especies del género Coffea son infestadas en diferente proporción. Es así como, en la Colección Colombiana de Café se identificaron introducciones etíopes de Coffea arabica y Coffea liberica con menor número de estados de este insecto, estas accesiones se están utilizando como progenitores masculinos para el desarrollo de una variedad de café que reduzca el número de individuos por generación, disminuya el crecimiento de la población y mantenga este coleóptero por debajo de los niveles de daño económico, a un bajo costo; una estrategia económicamente viable y de fácil adopción que contribuye a aumentar la eficiencia del manejo integrado de esta plaga. La evaluación de la población F2 de líneas de variedad Castillo® por tres introducciones etíopes demostró antibiosis en 68 plantas debido a la reducción de la reproducción, confirmando que esta característica se hereda a las siguientes generaciones. Adicionalmente se determinó que el porcentaje de estados de la broca de las plantas F2 con relación a los testigos susceptibles presenta una distribución normal, segregación típica de un carácter cuantitativo donde intervienen varios genes. Las poblaciones se avanzarán hasta la obtención de una variedad tolerante a esta plaga con características agronómicas deseables.
Cosecha Asistida: Optimice mano de obra y reduzca costos de recolección de café
Authors: Sanz Juan Rodrigo
Published: October 2022

El concepto de Cosecha Asistida en la recolección de café en Colombia implica tres prácticas que son: retención de pases, recolección manual de café con lonas y la cosecha semi-mecanizada con el uso de la Derribadora DSC18. La primera práctica consiste en extender los pases de cosecha por más tiempo, con el fin de aumentar la oferta de frutos maduros en los árboles. La cosecha con lonas, que requiere de la práctica de retención de pases para mejor desempeño, consiste en desprender los frutos maduros y dejarlos caer sobre lonas que se extienden sobre el suelo, logrando disminuir los tiempos usados en la cosecha hasta el punto que se logran incrementos importantes. La cosecha con derribadora DSC18, que también debe ser usada con las prácticas anteriores, consiste en utilizar la máquina para desprender los frutos maduros en los árboles. Las pruebas de campo indican que el aumento en la masa de café cosechable producto de la retención, más la reducción de movimientos para desprender los frutos del árbol al usar las lonas, pueden incrementar la eficiencia de la recolección en un 40%, y que el uso de la máquina DSC-18 puede aumentar esa eficiencia en 180% en promedio. La calidad de la recolección es aceptable.

Published: October 2022

En el marco del Proyecto de Ciencia, Tecnología e Innovación en el cultivo de café ajustado a las condiciones particulares de departamento del Huila (Colombia), se caracterizó la fertilidad del suelo en sus componentes químicos y físicos. Para ello, se tomaron 6.000 muestras de suelo para análisis químicos y 1.000 para análisis físicos; adicionalmente, mediante técnicas de laboratorio se determinaron los requerimientos de cal (incubación) y la dinámica de fósforo, calcio, magnesio y potasio (isotermas de adsorción) en las unidades cartográficas del suelo más representativas. Los resultados indican que, en el ámbito departamental, el 92% de los lotes evaluados presentan niveles bajos a muy bajos de materia orgánica (menor de 8%), el 53% exhiben algún grado de acidez, el 41% valores bajos de fósforo (menor de 10 mg kg-1) y el 58% tenores bajos a medios de potasio (menor de 0,40 cmolc kg-1). En la mayoría de los casos fueron bajos los contenidos de azufre, mientras que solo el 4% de las muestras analizadas presentan niveles muy bajos de calcio y magnesio intercambiables (0,75 cmolc kg-1 y 0,30 cmolc kg-1, respectivamente). Con respecto a los micronutrientes, fueron elevados los niveles de hierro, medios los de cobre, manganeso y zinc, y bajos los de boro. Respecto a las variables físicas, los suelos del 36% de los lotes presentaron densidades aparentes mayores a 1,2 g cm-3, el 28% texturas catalogadas como críticas (Ar, A, L, ArA y AL) y el 60% una baja capacidad para retener agua. De acuerdo con los resultados, se generaron recomendaciones para el manejo de la fertilidad del suelo y la nutrición de los cafetales a escala departamental, zona agroecológica y municipal; además, en la página de Cenicafé, se creó un aplicativo para visualizar el resumen de los resultados, bien sea como tablas o mapas.

A large fraction of Type Ia supernova (SN Ia) observations over the next decade will be in the near-infrared (NIR), at wavelengths beyond the reach of the current standard light-curve model for SN Ia cosmology, SALT3 (∼2800–8700 Å central filter wavelength). To harness this new SN Ia sample and reduce future light-curve standardization systematic uncertainties, we train SALT3 at NIR wavelengths (SALT3-NIR) up to 2 μm with the open-source model-training software SALTshaker, which can easily accommodate future observations. Using simulated data, we show that the training process constrains the NIR model to ∼2%–3% across the phase range (−20 to 50 days). We find that Hubble residual (HR) scatter is smaller using the NIR alone or optical+NIR compared to optical alone, by up to ∼30% depending on filter choice (95% confidence). There is significant correlation between NIR light-curve stretch measurements and luminosity, with stretch and color corrections often improving HR scatter by up to ∼20%. For SN Ia observations expected from the Roman Space Telescope, SALT3-NIR increases the amount of usable data in the SALT framework by ∼20% at redshift z ≲ 0.4 and by ∼50% at z ≲ 0.15. The SALT3-NIR model is part of the open-source SNCosmo and SNANA SN Ia cosmology packages.
JWST Sneaks a Peek at the Stellar Morphology of z ∼ 2 Submillimeter Galaxies: Bulge Formation at Cosmic Noon

Published: October 2022

We report morphological analyses of seven submillimeter galaxies (SMGs) at z ∼ 2 using the James Webb Space Telescope NIRCam images taken as part of the public CEERS and PRIMER surveys. Through two-dimensional surface brightness profile fitting we find evidence of compact reddened stellar structures in all the SMGs, in particular in the F444W filter, suggesting an ubiquitous presence of stellar bulges. The median size of these bulges at F444W with a bootstrapped uncertainty is found to be 0.7 ± 1.0 kpc (0.6–0.7–3.9 kpc for 14th–50th–86th percentiles) and the median Sérsic index is 0.7 ± 0.9 (0.4–0.7–2.8 for 14th–50th–86th percentiles). Structures akin to spiral arms and bars are also identified, and their asymmetric shapes, tidal features, as well as evidence of nearby galaxies at consistent redshifts as those of corresponding SMGs suggest that these SMGs are undergoing dynamical interactions, likely responsible for the triggering of their star-forming activity. Via a curve-of-growth analysis we deduce half-light radii for the NIRCam wave bands, finding that sizes are significantly smaller at longer wavelengths in all cases, in particular that the median size ratio between F444W and F150W is 0.6 ± 0.1. However, we also find that F444W sizes, roughly corresponding to rest-frame H band, are not smaller than those of submillimeter continuum as measured by the Atacama Large Millimeter/submillimeter Array, contradicting certain recent predictions from theoretical models. Our results suggest that while stellar bulges are undergoing an active formation phase in SMGs at z ∼ 2, the total stellar masses of SMGs are still dominated by their disks, not bulges.
A Significant Sudden Ionospheric Disturbance Associated with Gamma-Ray Burst GRB 221009A
Authors: Hayes Laura A. , Gallagher Peter T.
Published: October 2022

We report the detection of a significant sudden ionospheric disturbance in the D-region of Earth’s ionosphere (∼60–100 km), which was associated with the massive γ-ray burst GRB 221009A that occurred on 2022 October 9. We identified the disturbance over northern Europe—a result of the increased ionization by X- and γ-ray emission from the GRB-using very low frequency radio waves as a probe of the D-region. These observations demonstrate that an extra-galactic GRB (z ∼ 0.151) can have a significant impact on the terrestrial atmosphere and illustrates that the Earth’s ionosphere can be used as a giant X- and γ-ray detector. Indeed, these observations may provide an insight into the impacts of GRBs on the ionospheres of planets in our solar system and beyond.

Published: October 2022

The definition of typical species inventories of the 92/43/EEC Directive habitat types is a valuable information for the optimization of the conservation status assessment. Habitat-specific assessment protocols and predefined local inventories of typical species provide a method for a relatively fast and accurate assessment of the criterion “structures and functions”. Habitat types are often defined and described on the basis of a phytosociological description of vegetation units, mainly at the syntaxonomical level of alliance. Therefore, the definition of typical species inventories can be based on phytosociological approaches. Within this concept we surveyed the vegetation of a NATURA 2000 Special Area of Conservation in northern Greece in order to optimize and downscale the existing region-wide inventories of typical species. In total, we sampled 164 relevés in beech and in thermophilous deciduous broadleaved forests. The relevés were assigned to vegetation units and habitat types using numerical approaches and their differential and constant taxa were defined. We used these taxa to draw up the optimized, site-specific inventories of typical species for seven habitat types of community interest and one habitat type of national interest.

Authors: Delahaie Noélie
Published: October 2022

Depuis plus de deux ans, la crise sanitaire liée à la pandémie de Covid-19 met fortement à l’épreuve le marché du travail irlandais. Craignant une crise durable et profonde, le gouvernement met en place dès mars 2020 une politique inédite de soutien aux revenus et à l’emploi. Cet article montre que si les mesures pandémiques ont permis une sortie de crise rapide, de fortes pénuries de main-œuvre affectent les secteurs à hauts salaires et bas salaires, engendrant ainsi une montée des tensions sur le marché du travail.

Les questions de la clôture et de la claustration sont essentielles et intimement liées dans le Voir Dit de Guillaume de Machaut. Le texte, où prolifèrent les rondeaux et dont la Roue de Fortune gouverne la narration, comprend en outre nombre de scènes où l’enfermement est thématisé : enfermement des objets, tel le portrait de Toute Belle, confinement des amants dans leurs chambres ou dans l’auberge de la Foire du Lendit, menace de prise de corps par les Grandes Compagnies, finalement détournée par le biais de l’allégorie, tout le Voir Dit métaphorise en fin de compte la possibilité qu’a la littérature d’enclore le secret ultime des amants.

A cascade flocking model with feedback
Authors: Liu Yuhang , Li Le
Published: October 2022

We study intelligence control systems and propose a new cascade flocking model with feedback. Compared to the one-way nature of past flocking models, our model adds a feedback mechanism, which means that the followers can have an influence on the direct leader's action. We demonstrate that these models can form a flock under specific conditions. This makes the flocking model more suitable for realistic applications.
Path to green development: the role environmental regulation and labor skill premium on green total factor energy efficiency
Authors: Ren Siyu , Wu Haitao
Published: October 2022

Improving energy efficiency is critical to breaking the resource curse. Using the GML Productivity Index, we measured the China's green total factor energy efficiency (GTFEE) and systematically explored the effects of environmental regulations on GTFEE. This article focuses on the threshold effect of environmental regulation (ER) on GTFEE at different skill premium levels. The conclusion shows that the impact of ER on GTFEE is expressed as a U-shaped relationship. ER can not only directly increase the skill premium, but also indirectly improve the GTFEE by increasing the skill premium. In addition, the threshold effect analysis suggests that skills premiums can enhance the role of ER in promoting GTFEE. Based on a new perspective on labor skills premiums, this study analyzes the mechanisms of environmental regulation to promote GTFEE, which has enlightening significance for improving the pollution control effect of ER and promoting carbon neutrality in China.

Liaisons troubles en maison close
Authors: Zani Beatrice
Published: October 2022

À partir d’une ethnographie du travail des femmes migrantes chinoises employées dans une maison close de Taipei, le récit propose une réflexion sur l’éthique de l’enquête. Il narre la production de complicités entre l’ethnographe et une pluralité d’acteurs : le maquereau local, ses partenaires, ses subalternes et les femmes. Construites in situ, les complicités se révèlent précaires et temporaires : elles se font et se défont, débouchant sur une complicité in fine impossible, faite d’ambivalences, de mensonges, de proximités illusoires, d’échanges éthiquement douteux. Dans la maison close, des relations sociales équivoques sont agencées et hiérarchisées en fonction d’intérêts personnels, de relations de pouvoirs et de complicités ambiguës au sein desquelles l’ethnographe négocie sa présence, fragile, précaire, mais est expulsée du terrain quand les complicités se rompent.

Published: October 2022

La guerre Iran-Irak (1980‑1988) a fait des centaines de milliers de victimes parmi les combattants volontaires, dont de jeunes pères de famille. Les orphelins de ceux qui s’étaient engagés ont aussitôt été considérés comme les futurs porteurs des valeurs révolutionnaires. Constituant une nouvelle catégorie de la population, ils ont été pris en charge par l’État avant même d’être en mesure de décider pour leur sort. Afin de montrer concrètement la situation malaisée de certains de ces individus, tenus pour « complices » dans une société fortement clivée depuis la fin de la guerre, ce récit non fictif présente l’histoire d’une femme de 36 ans, mariée et mère de deux enfants. Elle n’a aucun souvenir de son père qu’elle a perdu à l’âge de deux ans.
Improving Rumor Detection by Image Captioning and Multi-Cell Bi-RNN With Self-Attention in Social Networks
Authors: Wang Jenq-Haur , Huang Chin-Wei , Norouzi Mehdi
Published: October 2022

User-generated contents in social media are not verified before being posted. They could bring many problems if they were misused. Among various types of rumors, the authors focus on the type in which there's mismatch between images and their surrounding texts. They can be detected by multimodal feature fusion in RNNs with attention mechanism, but the relations between images and texts are not well-addressed. In this paper, the authors propose to improve rumor detection by image captioning and RNNs with self-attention. Firstly, they utilize the idea of image captioning to translate images into the corresponding text descriptions. Secondly, these caption words are represented by word embedding models and aggregated with surrounding texts using early fusion. Finally, multi-cell bi-directional RNNs with self-attention are used to learn important features to identify rumors. From the experimental results, the best F-measure of 0.882 can be obtained, which shows the potential of our proposed approach to rumor detection. Further investigation is needed for data in larger scale.

Published: October 2022

The catastrophic outbreak COVID-19 has brought threat to the society and also placed severe stress on the healthcare systems worldwide. Different segments of society are contributing to their best effort to curb the spread of COVID-19. As a part of this contribution, in this research, a clustering-based recommender system is proposed for early detection of COVID-19 based on the symptoms of an individual. For this, the suspected patient's symptoms are compared with the patient who has already contracted COVID-19 by computing similarity between symptoms. Based on this, the suspected person is classified into either of the three risk categories: high, medium, and low. This is not a confirmed test but only a mechanism to alert the suspected patient. The accuracy of the algorithm is more than 85%.

Published: October 2022

Literature has mainly analyzed the technical attributes of voice for enterprise technical applications, such as voice signature and speech recognition. This paper aims at identifying voice and speech attributes that reflect sentiment and affect (positively or negatively) customer satisfaction levels in voice interactions. The paper used method triangulation that utilizes multiple data sources to gain comprehensive understanding of the domain, including auditory observations, focus group interviews, customer survey, and a review of recent academic studies. The findings indicate that customer experience and satisfaction are influenced by the relative values of voice pitch between the CSR (customer service representative) and the customer. The major conclusion of the study suggests that voice fundamental pitch, speech rate, voice amplitude, and other communication parameters might deploy hidden power and affect service interaction's results. The study opens a new venue for research on social interaction adjustment from the CSR's perspective and from the customer's standpoint.

Authors: Lu Chun-Yi Jiunn-Yin , Wu Hsin-Te
Published: October 2022

This study proposes using dendrogram clustering as the basis to construct a federated learning system for A.I. model parameter updating. The authors adopted a private blockchain to accelerate downloads of the latest parameters corresponding to the computation results of an A.I. model. This study reduced the computational complexity of the backend server with the A.I. model to elevate backend server performance. Furthermore, the authors propose a hash function to determine whether the machines added new training data. The experimental results revealed that the proposed method could reduce the computational complexity of federated learning and that private blockchains can be applied to ensure parameter confidentiality and completeness. In summary, this research uses software computing methods to save machine learning data transmission, reduce network load, and provide privacy protection for parameter data without updating existing production equipment so that small-cost enterprises can import Industry 4.0.

Published: October 2022

This study aimed to investigate the effects of the COVID-19 crisis on the performance of the stocks of Brazilian agribusiness. Among the main activities of Brazilian agribusiness, grain production stands out worldwide. Thus, we selected the company SLC to represent this segment. And, from Thomson Reuters, we selected its peer companies: Ambev, JBS, BRF, Cosan Logística, Marfrig and São Martinho. We used the event study methodology and multivariate linear regression. The results showed that SLC performed well in the event window, while its peers experienced great volatility. The OLS regression confirmed that SLC was positively differentiated from other companies with daily trading in the period.
Impact of Perceived Social Support and Social Skills on Adolescent’s Self- Esteem: The Social Support Theory Perspective
Authors: Karunarathne R. A. I. C.
Published: October 2022

Adolescents place more emphasis on social relationships which help them to develop a positive selfview. Based upon social support theory, this study aimed to examine the impact of perceived social support, measured from three trajectories (perceived family support, perceived friends support, and perceived significant other support) on adolescent’s self-esteem and the moderating effect of social skills. To attain this objective, we developed a conceptual model and collected data from 253 bachelor students in a state University, Sri Lanka. Data were analyzed with the aid of SmartPLS 3.3. The results of this study showed that perceived support from family, friends, and significant others significantly influences adolescents' self-esteem development. Moreover, the results of moderation analysis showed that social skills moderate only the association between perceived friend support and selfesteem. The study's data collection was limited to one point in time, and we could not capture how self-esteem develops over time. Thus, future researchers need to examine our research model over different time points. Theoretical and practical implications are discussed.
Financial Statement Informativeness and Intellectual Capital Disclosures: With Special Reference to the Listed Companies in Sri Lanka
Authors: Ariyawansa H. D. G. R. , Nanayakkara K. G. M.
Published: October 2022

Growing demand for financial and non-financial information by the users of financial reports leads to an emphasis on the informativeness of financial statements. Thus, reporting reliable and relevant financial and non-financial information becomes vital, and investments in intellectual capital, being highly demanding information by the users, hold an important place in providing informative financial reports despite the lack of proper accounting recognition criteria in financial statements. Thus, our study aims to analyze the relationship between financial statement informativeness and intellectual capital disclosure in Sri Lanka. Financial Statement Informativeness was measured using the explanatory power of financial information in explaining market value. Content analysis of annual reports followed by a quantity and quality index of Intellectual Capital Disclosure was used to measure the Intellectual Capital Disclosures. A sample of 48 companies listed on the Colombo Stock Exchange that disclose Intellectual Capital was used, and empirical analysis was carried out using the Poisson regression method. A significant relationship between Financial Statement Informativeness and Intellectual Capital Disclosures has been found, suggesting that Financial Statement Informativeness plays a substantial role in providing disclosure on intellectual capital in financial reports. This study confirms to make managers aware of its significant and positive effect on financial statement informativeness in financial reports, given the importance of Intellectual Capital Reporting in mitigating the disparity of financial information. An important implication of the findings is that policymakers and regulators need to establish a uniform methodology for reporting Intellectual Capital to establish consistent disclosure practices.
The Effect of Environmental, Social and Governance Disclosures on Firm Value: With Special Reference to Listed Firms in CSE
Authors: Viduranga J. M. K. , Fernando J. M. R.
Published: October 2022

This study empirically verifies whether the environmental, social, and governance disclosures impact on firm value of the companies listed on the Colombo Stock Exchange. The Data were drawn from published annual reports and sustainability reports covering the period from 2014/2015 to 2018/2019 relating to 50 companies. The study developed individual and integrated indices to measure the ESG disclosures and examine the individual and collective effect of ESG disclosures on firm value. The study found that social and governance disclosures positively and significantly impact firms' value, whereas environment disclosures do not significantly impact firms' value. However, integrated ESG disclosures positively and significantly influence the firm value. The study suggests that the market positively and significantly values the social and corporate governance disclosures as well as the combined ESG disclosures carried out by the companies in Sri Lanka. This study contributes to the extant literature being the first empirical study to examine the impact of ESG factors on the value of the Sri Lankan public quoted companies.
The burden of epilepsy: data from an epilepsy clinic
Authors: Gamage Ranjanie , Gooneratne Inuka Kishara
Published: October 2022

Introduction: Over half of the 50 million people with epilepsy worldwide are estimated to live in Asia, but information about the recognition of the burden created by the disease is scarce. Studies in the region and in Sri Lanka focusing on the burden of epilepsy are limited. Design/Setting: A retrospective hospital-based study was conducted to determine educational, marital, and employment opportunities of patients with epilepsy attending the epilepsy clinic at the National Hospital of Sri Lanka for one year. An interviewer based questionnaire was used to collect data. Results: Data was gathered from 500 patients. Male to female ratio was 1.08:0.92. Two hundred and twelve patients (42.4%) belonged to the 16 to 30 age group while 140 (28%) were from the 31 to 45 age group. Most of the patients in the aforesaid age groups (n=352) were unemployed (n=211, 59.94%) and only 89 (25.3%) were employed. Two hundred and sixty four patients (75%) were unmarried while 7 (1.9%) were divorced. The number of patients who received primary and secondary education were 44 (24.4%) and 93 (51.6%) respectively. Two (1.1%) patients went to university. Forty one (22.8%) had no schooling. Interpretation: Many epilepsy patients have fewer educational, marital, and employment opportunities which contribute towards poor interpersonal skills, social withdrawal and low selfesteem. This emphasises that epilepsy is a chronic disabling neurological disorder which causes many psychosocial tribulations that need to be addressed by healthcare professionals.

Authors: Arasalingam A. , Kumanan T. , Kamalakkannan K. , Visvakumar M. , Wimalawardhana R. M. M. P.
Published: October 2022

Objective: To determine the stroke subtypes and risk factors in the Jaffna district and to determine if it differed from the rest of Sri Lanka. Methods: A hospital based prospective, cross sectional study was carried out in 448 stroke patients admitted to the Jaffna Teaching Hospital, from December 2014 to August 2015. Diagnosis of stroke was made according to the WHO definition and confirmed by a CT brain. The patients were investigated for conventional risk factors. The data was statistically analyzed using SPSS. Results: There were a total of 448 cases included in the study of which 226 (50.45%) were males and 222 (49.55%) were females. The mean age of the patients was 66.0 ± 12.23 for males and 67.25 ± 12.12 for females. Stroke subtypes showed preponderance for ischaemic strokes (84.15%). Hypertension was the commonest risk factor (56%) and the other risk factors were ranked as follows; past history of stroke (39.4%), smoking (30.8%), diabetes mellitus (26.05%), dyslipdaemia (15.8%), family history of stroke (12.3%) and ischaemic heart disease (11.9%). Conclusions: Ischaemic stroke was the commonest subtype and lacunar stroke was the commonest presentation according to the OCSP classification. Hypertension was the commonest risk factor. Preventive strategies to detect hypertension and diabetes early and public awareness of the ill effects of smoking should contribute significantly in the reduction of stroke burden.

Purpose of the study: To describe the demographic factors, pattern of anti-Parkinsonism drugs used and to identify factors influencing treatment in PD patients attending Colombo South Teaching Hospital (CSTH) in Sri Lanka.Methods: A descriptive cross sectional study was conducted at CSTH during March 2012 - September 2012, recruiting patients with PD (according to diagnostic criteria of the United Kingdom Parkinson’s Disease Society Brain Bank) attending neurology and medical clinics.Results: There were 103 PD patients, with a mean age of 64 yrs (SD 9.6, range 43-86) and 58 (56.3%) were males. Duration of illness ranged from 1 month to 15 yrs (median 2 yrs) and average age of onset was 61yrs (SD 9.6, range 41 - 82). 13 patients (12.6%) had onset of PD before 50yrs. Majority (n=57, 55.3%) had at least one co-morbidity. Levodopa alone was the treatment in 100 (97.1%) patients, Ropinirole alone in one, and 10 (9.7%) on Levodopa and Ropinirole combination with 2 (2%) drug-naïve patients. Benzhexol was used in 82 (79.6%) patients. Sex, disease severity, duration of illness, education level or employment status did not differ between treatment groups.Conclusion: PD is a commonly seen neurodegenerative disorder in hospital outpatient clinics and majority had other co-morbidities. Levodopa and Benzhexol are the commonly used drugs in Sri Lanka. Use of dopa agonists are much less common when compared to other countries. Age, the age of onset of PD, cost, and availability are major determinants of treatment.
New pathogens causing CNS infections
Authors: Ranawaka Udaya K.
Published: October 2022

Many emerging infections, mainly viruses, are contributing to the reshaping of the global landscape of central nervous system (CNS) infections. Several new organisms causing CNS infection have been discovered over the last decade, and new neurological syndromes have been described for many other known pathogens. Advances in diagnostic techniques such as modern DNA amplification methods have led to the detection of some of the newly identified pathogens. The global attention generated by disease epidemics has helped in the improved understanding of the neurological complications associated with some known pathogens, such as Zika virus, Ebola virus and Enterovirus D68. A better understanding of the evolution of the new pathogens, their hostvector- environment dynamics, and their disease causation is clearly needed for us to be better prepared to meet these emerging threats.

Palliative care in neurology
Authors: Oliver David
Published: October 2022

Palliative care is a very important part of the care for people with neurological disease, and their families. This may be appropriate in any patient group, but is particularly helpful for patients with progressive neurological disease and when the disease is progressing towards the end of life. A multidisciplinary approach allows the assessment and management of the various issues facing patients – physical, such as symptom management, psychological, social and spiritual. In this way the quality of life of patients can be maintained and preparations made for the end of life, so that they are able to have their symptoms managed effectively and die peacefully.
