The paper looks at the Khalistan movement, amidst the recent hunt and arrest of radical preacher Amritpal Singh. It studies how the movement has changed since the campaign for a sovereign Sikh state went global in the 1970s; and what the demand for Khalistan entails today. It studies the role the Sikh diaspora in the United Kingdom, Canada, Australia and the United States has played; and how recent events, particularly, protests at Indian High Commissions in these countries reflects the ambivalence of India’s ‘allies’ towards the separatists. The paper argues that while the nature of the threat posed by Khalistani separatists is much milder today than it was decades ago, the challenge for the Indian government will be the influence of the Sikh diaspora on foreign politicians and New Delhi’s ability to discredit the movement abroad.

In the two decades following the devastating Tsunami of 2004, India has emerged as a global leader not just in having a well-defined structure for mitigating disasters but also in providing humanitarian support to other countries affected by disasters. The Hyogo Framework for Action (HFA) (2005–2010) brought vulnerable communities in disaster zones into key focus of decision making; it also emphasized preparedness (resilience building to enable communities to bounce back faster) as an important area of state responsibility. The Sendai Framework (2015–2030) that followed Hyogo evolved further by indicating that ‘risk identification’ helps timely action. As disasters observe no political boundaries, so disaster management strives to overcome every political and ideological division to cooperate, collaborate, and hand hold affected nations. Resilience building includes a strategy to prevent other nations from succumbing to disasters its impact is never confined to the one victim nation alone but spreads to other nations in different ways. In the previous decade, India has unswervingly sent relief material as well as shared her experience, expertise, and technology for the longterm resilience building of several countries. The Disaster Management Act 2005 has provided a statutory framework for global resilience building, and the National Disaster Response Force (NDRF) as a new team of ‘Samaritan Diplomats’ has helped India in image building, winning trust, and forming alliances. This goes a long way in strengthening both resilient infrastructure and sustainable projects, such as the ‘Solar Alliance’, and also create sturdy platforms for encountering pandemics like the COVID-19. Disaster Management Diplomacy is a new buzz word as traditional military competitors have now also become competitors in humanitarian interventions — such as India and China in South Asia. While resilience building strategies help a peace building process, they also ensure continuity of supply chains in global business by linking resilience building with Sustainable Development Goals.
Public Speaking Training Plan for Mitigating Oral Communication Apprehension
Authors: Kho Marcus Gee-Whai , Ting Su-Hie
Published: August 2023

This paper presents a public speaking training plan adapted from Toastmasters International’s Handbook of Competent Communication to reduce students’ communication apprehension. The training plan draws on Kolb’s (1984) experiential learning theory, which links experience, perception, cognition and behaviour, making it particularly well suited for developing practical skills such as public speaking. The programme engages participants in a cycle of concrete experience, reflective observation, abstract conceptualisation and active experimentation consistent with successful public speaking training principles. The training addresses aspects of public speaking that often contribute to communication apprehension, such as language structure, language use, non-verbal communication and voice modulation. The programme also emphasises active experimentation through visual aids and the delivery of persuasive and inspiring speeches so that participants have ample opportunity to practise and hone their public speaking skills. This approach effectively reduces communication apprehension and gives students the skills and confidence to deliver impressive oral presentations. However, the effectiveness of this training plan can be influenced by various factors, such as cultural background, language proficiency, and individual personality traits. Therefore, successful training should be flexible and adaptable to meet learners’ different needs and contexts.
The Support and Rehabilitation of Refugees – Personal Opinion and Experience
Authors: Kelly Clive
Published: August 2023

Life isn’t meant to be easy for anyone. But some have it much harder than others. I’ve spent most of my life looking after people with disability and disease. And within the last decade, I’ve also become involved in caring for refugees. Western society is generally sympathetic to those with illness, and at least until recently, those of us responsible for their care have received recognition and usually appreciation. However, our society is much more divided when it comes to refugees. Opinions vary widely and there has been significant resistance to accepting refugees into the UK and some other western countries. Supporting them, even in their own country can generate adverse comments or criticism, sometimes from unexpected quarters. This article is a reflection on my role, both as a doctor and a humanitarian, in supporting refugees in their own country. I describe my experience and achievements, along with the challenges we have faced. I invite comments and constructive criticism, because I believe it is important to share and exchange opinions and experience without rancour.
Profilaxia da Sindrome da Toxicidade Precoce por Quimioterapia pelo uso de Antiprostaglandínicos: Corticosteroides ou Cetoprofemo
Authors: Delgado Gilson L. , Stefanuto Walter
Published: August 2023

Foram estudados prospectivamente 29 pacientes, que foram aleatoriamente distribuídos em dois grupos de tratamentos: tratamento C-hidrocortisona (500mg) intravenosa, ou dexametasona (20mg) intravenosa; e tratamento P-cetopro feno intramuscular (3 x 50mg). Ambos os tratamentos eram associados com metoclopramida intravenosa (20mg). Todos os pacientes receberam esquemas quimioterápicos sem o envolvimento de cisplatinum. Não se conseguiu observar diferenças entre os dois tratamentos profiláticos para as náuseas, vômitos, anorexia, astenia, artralgias/mia/gias, sonolência, insônia, e, semiquantitativamente, para todos os sintomas da síndrome da toxicidade precoçe (STP). Conclui-se que o cetoprofeno é tão útil quanto o corticosteróide para a profilaxia da STP induzida por quimioterápicos não "potente emetizantes”, e que os resultados obtidos corroboram ainda mais para o modelo patogênico teórico proposto, e que envolve a mediação de prostaglandinas e leucotrienos na gênese dos sintomas da STP.

Published: August 2023

O objetivo deste estudo foi avaliar o potencial fitoquímico e alelopático do extrato aquoso das folhas da Petiveria alliacea na germinação e no crescimento inicial de plântulas de alface (Lactuca sativa L.). A análise fitoquímica foi realizada por técnicas colorimétricas e de precipitação. Para avaliar o potencial alelopático quatro concentrações (25%, 50%, 75% e 100%) foram estipuladas e as sementes de alface foram mantidas em contato com as mesmas por 72 horas. Os parâmetros avaliados foram: porcentagem de germinação, índice de velocidade de germinação, peso fresco e comprimento das plântulas (raiz e parte aérea). O estudo revelou que a Petiveria alliacea possui compostos químicos de 9 diferentes classes, incluindo, alcalóides, cumarinas, esteroides, fenóis, flavonoides, saponinas e taninos. A porcentagem de germinação foi afetada significativamente pelos extratos nas concentrações de 75% e 100%. Na concentração mais alta (100%), o extrato resultou em uma redução de 85,10% na porcentagem de germinação. Além disso, todas as concentrações do extrato foram capazes de inibir significativamente o índice de velocidade de germinação, o comprimento e o peso fresco das plântulas. Conclui-se que a Petiveria alliacea apresenta grande potencial como bioherbicida devido à sua capacidade de inibir a germinação e o crescimento das plântulas.

Trust, but customize: federalism’s impact on the Canadian COVID-19 response
Authors: Migone Andrea
Published: August 2023

This article explores how Canadian federalism, with its complex mix of competencies, and the country’s punctuated gradualism policy style interface with urgent, complex decision-making like the COVID-19 pandemic. We find that while punctuated gradualism favors tailored responses to pandemic management it is weaker when coordination and resourcing are to be undertaken during non-crisis situations and that, while the level of cooperation among Canadian jurisdictions has progressively increased over the years, policy is still almost exclusively handled at the federal, provincial and territorial levels. Furthermore, the model appears to have critical ‘blind spots’ in terms of vulnerable communities that do not emerge as such until after a crisis hits.
The influence of national policy characteristics on COVID-19 containment policies: a comparative analysis
Authors: Migone Andrea
Published: August 2023

This article discusses the correlation between national policy characteristics and the success in “flattening the curve” of infection of the COVID-19 virus, which is a generally acknowledged measure to contain the worst medical outcomes of a pandemic. While individual cases require careful and granular analysis to properly unpack, the article finds that the best correlation is found when looking at the pattern of choice related to either proactive or reactive approaches to the implementation of containment measures. This is especially evident for countries that have either very low or very high infection rates per million persons. For intermediate rates we find that a variety of institutional, political, and procedural variables intervene in the process.
The unfulfilled potential of dogs in studying behavioural evolution during the Anthropocene
Authors: Hansen Wheat Christina , Wynne Clive
Published: August 2023

While dogs represent an exceptional resource for studying ecological, behavioural and evolutionary processes, they are severely under-represented within these fields due to the anthropomorphisation of dog behaviour, and the view that dog domestication was solely human-driven. These widespread misconceptions have not only led to significant problems in understanding dog behaviour, but also inhibited the use of dogs as valuable study systems to advance diverse areas of biological sciences. Here we argue that dogs should be studied using the same fundamental principles of ecology and evolution applied to other species. Specifically, two of Tinbergen’s four questions remain critical, yet understudied, in understanding dog behavioural traits: 1) What is the current value of these behaviours, and 2) How did they arise and subsequently evolve? We address dog behaviour in a range of ecologies beyond just the pet niche. In doing so three main facts emerge: 1) dogs show a wide range of behavioural adaptations to human proximity, 2) the behaviour of dogs has changed rapidly over time within human niches, and 3) the behaviour of dogs can be understood as modifications of pre-existing variation in their ancestral species, wolves. As this point is commonly overlooked in the majority of the dog behavioural literature, the result is a growing body of biassed research that cannot be meaningfully integrated with, for example, canine functional genomic studies. Resituating dogs within biological research will: 1) advance behavioural genetics and genomics, 2) help establish how certain species are able to adapt to anthropogenic environments where so many fail, 3) enable dogs to serve as model organisms in a range of sciences.

Climate change has pervasive impacts on Earth’s ecosystems, but the diversity and complexity of ecosystems makes estimating the severity of impacts and the resulting risk of collapse difficult. In this perspective, we conceptualise the challenge of understanding how climate change alters ecosystems, and how to reliably measure those changes in ecosystem risk assessments, focussing on the IUCN Red List of Ecosystems. We propose solutions to resolve these challenges – using diverse teams, conceptual models, diverse using data sources including projections, learning from analogous ecosystems, and evaluating uncertainties – and we identify research gaps to bridge these challenges. Together, these solutions will improve our capacity to produce reliable assessments of collapse risk under climate change to inform timely and effective ecosystem conservation.

Published: August 2023

O líquen plano oral é uma doença autoimune, visível clinicamente como estrias esbranquiçadas denominadas estrias de Wickham e que, embora não tenha etiologia definida, está associada a alguns possíveis fatores causais, como: condições emocionais, uso de alguns materiais dentários, medicamentos, hábitos nocivos e em decorrência de trauma. Tende a se manifestar de seis formas diferentes: tipo placa (lesões brancas), papular, ulcerativo, atrófico, bolhoso (lesões vermelhas) e o reticular, que é o mais comum e frequente. Não é uma regra, mas em alguns casos são comuns o surgimento de sinais e sintomas, como dor, sensação de aspereza, alteração da percepção dos sabores e reações cutâneas. Seu diagnóstico é formado por um conjunto de ações. O trabalho objetiva descrever as características clínicas e histológicas, sua etiologia, suas manifestações intra e extra orais, bem como seus sinais e sintomas, para estabelecer seu diagnóstico diferencial. Para desenvolvimento da revisão, foi feita uma busca de artigos publicados entre 2013 e 2023, que fossem em português ou inglês, desprezando os que não atendessem aos critérios de seleção, ao final, foram usados 37 artigos para sua construção. Conclui-se pela análise dos artigos que é consenso entre os autores o método de diagnóstico, por meio da correlação das características clínicas e histológicas, histórico do paciente e uso de medicamentos e, quando necessário, deve-se biopsiar para que seja feita a imunofluorescência direta para distinção de doenças que possuem as mesmas características e tendem a causar confusão no processo de diagnóstico. Requere-se mais estudos aprofundados sobre o tema.

MUSIC RECOMMENDATION SYSTEM BASED ON COSINE SIMILARITY AND SUPERVISED GENRE CLASSIFICATION
Authors: Alyza Jamie Mayliana , Utomo Fandy Setyo , Purwati Yuli , Kusuma Bagus Adhi , Azmi Mohd Sanusi
Published: August 2023

Categorizing musical styles can be useful in solving various practical problems, such as establishing musical relationships between songs, similar songs, and finding communities that share an interest in a particular genre. Our goal in this research is to determine the most effective machine learning technique to accurately predict song genres using the K-Nearest Neighbors (K-NN) and Support Vector Machine (SVM) algorithms. In addition, this article offers a contrastive examination of the K-Nearest Neighbors (K-NN) and Support Vector Machine (SVM) when dimensioning is considered and without using Principal Component Analysis (PCA) for dimension reduction. MFCC is used to collect data from datasets. In addition, each track uses the MFCC feature. The results reveal that the K-Nearest Neighbors and Support Vector Machine offer more precise results without reducing dimensions than PCA results. The accuracy of using the PCA method is 58% and has the potential to decrease. In this music genre classification, K-Nearest Neighbors (K-NN) and Support Vector Machine (SVM) are proven to be more efficient classifiers. K-Nearest Neighbors accuracy is 64,9%, and Support Vector Machine (SVM) accuracy is 77%. Not only that, but we also created a recommender system using cosine similarity to provide recommendations for songs that have relatively the same genre. From one sample of the songs tested, five songs were obtained that had the same genre with an average accuracy of 80%.
Red wine polyphenols induce vasorelaxation via increased nitric oxide bioactivity
Authors: Zenebe W , Pecháňová O , Andriantsitohaina R
Published: August 2023

The aim of the present study was to investigate the mechanism of vasorelaxant responses induced by red wine polyphenolic compounds (Provinol). Rings of rat femoral artery with or without functional endothelium were set up in a myograph for isometric recording and precontracted with phenylephrine (10-5 M). Provinol in cumulative doses (10-9 to 10-3 mg/ml) elicited endothelium- and dose-dependent relaxation of the artery with maximal relaxation of 56 % at the concentration of 10-5 mg/ml. The relaxant responses to Provinol correlated well with the increase of NO synthase activity in the vascular tissue after administration of cumulative doses of Provinol (10-9 to 10-3 mg/ml). NG-nitro-L-arginine methylester (L-NAME, 3x10-4 M) significantly attenuated the endothelium-dependent relaxation produced by Provinol. Administration of L-arginine (3x10-5 M) restored the relaxation inhibited by L-NAME. The relaxant responses of Provinol were abolished in the presence of Ca2+-entry blocker, verapamil (10-6 M). Administration of hydrogen peroxide (H2O2) abolished acetylcholine (10-5 M)-induced relaxation of the rat femoral artery, while administration of Provinol (10-5 mg/ml) together with H2O2 helped to maintain the acetylcholine-induced relaxation. Provinol only partially affected the concentration-response curve for the NO donor sodium nitroprusside-induced relaxation in rings without endothelium. In conclusion, Provinol elicited endothelium-dependent relaxation of rat femoral artery by the Ca2+-induced increase of NO synthase activity and by protecting NO from degradation.
Hepatoprotective effect of rooibos tea (Aspalathus Linearis) on CCl4-induced liver damage in rats

Published: August 2023

Hepatoprotective properties of rooibos tea (Aspalathus linearis) were investigated in a rat model of liver injury induced by carbon tetrachloride (CCl4). Rooibos tea, like N-acetyl-L-cysteine which was used for the comparison, showed histological regression of steatosis and cirrhosis in the liver tissue with a significant inhibition of the increase of liver tissue concentrations of malondialdehyde, triacylglycerols and cholesterol. Simultaneously, rooibos tea significantly suppressed mainly the increase in plasma activities of aminotransferases (ALT, AST), alkaline phosphatase and billirubin concentrations, which are considered as markers of liver functional state. The antifibrotic effect in the experimental model of hepatic cirrhosis of rats suggests the use of rooibos tea as a plant hepatoprotector in the diet of patients with hepatopathies.
Cerebrolysin inhibits lipid peroxidation induced by insulin hypoglycemia in the brain and heart of mice
Authors: Patočková J , Kršiak M , Marhol P , Tůmová E
Published: August 2023

As a consequence of enhanced production of oxygen free radicals, lipid peroxidation leads to the degradation of membrane lipids and disturbances of membrane permeability. Lipid peroxidation increases under stress conditions such as hypoxia, ischemia or acidosis as well as in metabolic diseases, e.g. diabetes mellitus. We have shown that subcomatous doses of insulin (6.0 IU/kg) significantly increase thiobarbituric acid reactive substances (TBARs), especially malondialdehyde (MDA) – the endproduct of lipid peroxidation, in the brain and heart of mice. In our model of insulin-induced hypoglycemia, mice were treated with the neuroprotective, peptide-containing drug Cerebrolysin (100 mg/kg b.w.). Animals were sacrificed by decapitation two or three hours after the injection of tested substance and samples were taken to determine several serum parameters (glucose, total protein, triglycerides and lactic acid) and TBARs in the brain and heart. Although Cerebrolysin was not able to affect serum parameters after subcomatous insulin injection, the drug significantly influenced lipid peroxidation. A single injection of Cerebrolysin already decreased TBARs levels in the brain and heart tissue. Presuming that an increase of TBARs reflects disturbances of the cell membrane, we have documented a promising effect of Cerebrolysin on cell integrity.

Development of Electronic Student Worksheets Based on the Discovery Learning Model to Facilitate Mathematical Understanding Ability of Class XI SMA/MA Students in Limit Function Material
Authors: Aisyah Nur , Kartini  , Solfitri Titi
Published: August 2023

This research is motivated by the importance of students' mathematical understanding abilities in Indonesia, especially in Riau Province and the limited number of Student Worksheets that facilitate mathematical understanding abilities. Mathematical understanding is important for students because it becomes a prerequisite for further mathematical concepts, and meaningful learning will last longer. In facilitating students' mathematical understanding skills, meaningful learning is needed. One such learning is the Discovery Learning (DL) model. Applying a learning model alone is not enough to support the realization of an active learning process that can develop students' mathematical understanding abilities. Therefore, a teacher must provide facilities to support students, including developing Student Worksheets. Using appropriate digital technology in learning facilitates and attracts students' interest in learning so that learning becomes more effective. One of the sites that can make student worksheets more interactive by adding media in the form of motion animation, audio and video to it is a live worksheet. This study aimed to produce a product in the form of an electronic student worksheet based on the Discovery Learning (DL) model to facilitate mathematical understanding skills in class XI SMA/MA students on valid and practical Limit Function material. This research uses the ADDIE development model (Analysis, Define, Design, Development, and Evaluation). The resulting product is stated to be very valid and practical with an average percentage validity of 90%, and the average value of the questionnaire response results for students by 83%.

The enormous importance of numeracy skill to pre-elementary children has tasked teachers with the burden of imparting the skill in an effective manner. Despite the fact that literature has documented the effectiveness of games approach in children instruction, to some, use of game is disruptive to actual learning. This necessitates more experimental studies to further clear ambiguities about the use of games in pre-primary classrooms. This study examined the impact of games on pre-primary children’s interest and performance in numeracy. A pretest-posttest, control group, quasi-experimental was adopted. Fifty Nursery Two pupils were randomly assigned to treatment and control groups. The instruments used were Pre-primary Children’s Numeracy Achievement Test (r=0.86) and Pupils’ Interest in Numeracy Scale (r=0.81). The data collected were analyzed using Analysis of Covariance (ANCOVA) and Scheffe’s Post Hoc Pairwise Comparison. Results indicated that games method was effective on pre-primary children’s learning of numeracy (F (1, 42) = 373.502; P < 0.05) and also increased their interest in numeracy instruction (F (1, 42) = 9.773; P < 0.05). Based on these findings, recommendations were made that teachers, parents and curriculum developers should encourage the use of games method to improve numeracy instruction among pre-primary education.
