Published: January 2022

The roles of pharmacists are transforming throughout history and modern pharmacist has a crucial role in ensuring the efficacy and safety of applied drugs. It is a wonder that the pharmacy profession is still being viewed through an antiquated lens that is inconsistent with the diversity and extent of pharmacists’ current scope of practice. There is still much debate in the academic as well as the policy literature about the role of pharmacists and their unique contribution to healthcare. However, pharmacists have been variously characterized as makers of medicines, as pill pushers, pill counters, and bottle labelers, as managers, and as entrepreneurs. Given this variety of roles, the ‘professional identity’ of pharmacists could be viewed as problematic or confused. Having a clear professional identity provides a sense of worth, belonging, or purpose for the individual as well as the group and if that identity is unambiguous then the profession also becomes clearer and more focused. Thus, the purpose of this article was to provide an idea of the universal professional identity of pharmacists as healthcare practitioners’ under the Global Pharmacy Council (GPC). This GPC will enhance the impact of the profession of pharmacy on people’s lives in the context of healthcare trends.
La temporalidad en el empleo público como fallo activo en la administración
Authors: Nevado-Batalla Moreno Pedro T.
Published: January 2022

La elevada tasa de empleo temporal en la Administración Pública española se ha convertido en un problema estructural, en un fallo activo, que impide desarrollar una correcta gestión del personal, restando capacidad de eficacia y eficiencia a la organización pública. Los servicios públicos, como pilares del Estado del bienestar, se ven negativamente afectados por la imposibilidad material de desarrollar políticas de personal adecuadas a las necesidades reales de los ciudadanos. Esta situación tiene como principal causa el continuado incumplimiento de las normas reguladoras de la temporalidad, convirtiendo en ordinario, abusivo incluso, el uso de técnicas excepcionales. Los negativos efectos de este incumplimiento se advierten a través de la observación de los colectivos afectados y, en síntesis, del evidente daño al interés general poniendo en riego el modelo constitucional de empleo público, además de restar legitimidad y fortaleza a la propia Democracia. Resolver el problema, más allá de soluciones inmediatas basadas en la consolidación de situaciones de temporalidad y el refuerzo de medidas disuasorias, pasa por una mirada a largo plazo en la que el respeto a la legalidad sea el reflejo de una obligada y elemental lealtad institucional con el Estado democrático y de Derecho.

Hemodialysis as a treatment modality for Stage V chronic kidney disease (CKD) has significantly decreased mortality. However, there have been several studies reporting sensorineural hearing loss (SNHL) in these patients which affects their quality of life. The role of hemodialysis in its etiology has been widely debated and the strength of available evidence has not yet been evaluated. A systematic literature review was conducted to identify a possible association of hemodialysis to hearing loss and guide in making informed decisions in the management of CKD patients. Relevant articles from PubMed, ScienceDirect, EBSCO Medline, SCOPUS, Google Scholar, and Clinical Key were identified using Preferred Reporting Items for Systematic Review and Meta-Analyses framework. Studies that were published since the inception of the database to May 2020 and written in the English language were analyzed. A total of 36 articles on hemodialysis and sudden or SNHL were retrieved. Many were observational (13 cohorts, 10 case-control, seven case series, and six cross-sectional) studies involving 99,020 participants with ages ranging from 1 to 80 years. This review elucidates the occurrence of SNHL in CKD patients on hemodialysis. Yet, the available literature fails to provide conclusive evidence on hemodialysis as a causative agent for SNHL. Audiological assessment of all CKD patients before hemodialysis and regular follow-up may help in early diagnosis and better management of hearing loss.

Published: January 2022

The fight against COVID-19, which has become a global problem and still has an impact, still continues and a number of measures have been taken to mitigate the adverse economic impacts of the pandemic in Turkey. The measures taken affected each sector in the economy at different magnitudes. While results such as temporarily slowed-down production due to the first wave of the pandemic in certain production domains and decreased demand for manufactured goods have emerged, positive results also occurred due to the spread of remote online working as well as products such as food, cosmetics, hygiene and cleaning equipment, intense internet usage and the growth of manufacturing areas for smartphones, computers and so on, as well as increases in demand for those products. The extent to which sectors in the economy were affected throughout the pandemic has been an interesting research subject in the literature. Therefore, this study aims to examine the impacts of the COVID - 19 pandemic on the industrial, banking, and tourism sectors within the Turkish economy. In the study, over the period between March 11, 2020 – April 22, 2021, the number of confirmed daily infected cases was selected as the independent variable, whereas the XU100, XUSIN, XBANK, and XTRSM indexes were selected as dependent variables. The Toda Yamamoto causality test was performed in the study in which the COVID-19 outbreak was examined within the context of specific indexes. The analysis results indicated that a unilateral causal relationship existed running from the number of confirmed daily infected cases to all indexes under examination.

Published: January 2022

Bu makale, feminist ajandanın daha önceki yıllarında gündeminde yer almış olan hane içi emek meselesini ev işleri üzerinden Covid-19 salgını ile beraber düşünerek yeniden tartışmaya açmaktadır. Her şeyden önce dikkat edilmesi gereken en önemli hususlardan ve aynı zamanda bu makalenin ana vurgularından biri, hane içi emek biçimi olarak ev işlerinin görünmeyen ya da cinsiyetlendirilmiş yönünün patriyarkal kökleriyle birlikte uzun bir tarihe sahip oluşudur. Bunu kanıtlamak amacıyla makale ilk olarak meseleye dair salgından önceki durumun izini sürmekte, devamında ise tarihsel gelişim sürecinde itirazları ve görünmeyen hane içi emek üzerinden feministlerin sistemlerle hesaplaşmasını dikkate almaktadır. Tarihsel olanın ışığıyla günümüze gelerek, görünmeyen hane içi emek biçimi olarak ev işlerine eleştirel bağlamda ve detaylı bir şekilde bakılmaktadır. Tüm bu tartışmalar sonucunda ev işlerinin cinsiyetlendirilmiş ve doğallaştırılmış yönlerine dair bu makalenin iddiası; “patriyarkanın süreğenliğini” ortaya koymaktır.

Authors: YILDIRIM Yavuz
Published: January 2022

Kamusal otoritelere yönelik tabandan yükselen düzenli baskılar, şikayetler, gerginlikler ve talepler modern siyasetin şekillenmesinde etkili olmuşlardır. Bu tarz mücadeleler, monarşilerden cumhuriyete ve demokrasilere geçişte tarihsel öneme sahiptir. Günümüzde bu dönüştürücülük devrimci nitelikte olmasa da önemini kaybetmiş sayılmaz. Demokrasilerin göstergeleri bağlamında bu yönde çekişmelerin varlığı her zaman temel kriterler arasındadır. Toplumsal muhalefetin demokrasiyi daha iyi hale getirme yolunda yeni mekanizma ve süreçleri geliştirmesi gerekmektedir. Türkiye’nin sorunlu demokrasi tarihindeki en önemli eksikliklerden birinin, kurumsal siyasetin toplumsal hareketlerin kolektif eylemleri tarafından yönlendirilememesi olduğu söylenebilir. Çoğunlukla odaklanılan karar vericiler ve güç odakları dışında, bir siyasal sistemin analizi muhalefet güçleriyle de alakalıdır. Çalışma “Türkiye’nin güçlü toplumsal muhalefeti ve onun içinde beslenen etkili toplumsal hareketleri var mı?” sorusu etrafında, toplumsal hareketlerin belirleyici gücünün eksikliği ile Türkiye demokrasisi arasında bağı analiz etmektedir. Mevcut hegemonyanın kurduğu sosyo-ekonomik ağ kadar, demokratik güçlerin kur(a)madığı ağlar da sistemin gelişiminde üzerinde etkili olmuştur. Çalışmada hareketlerle demokratik sistem arasındaki bağlantılar genel hatlarıyla ortaya konduktan sonra, Türkiye özelinde dinamik çekişmeci aktörlerin eksikliği nedeniyle hareketlerin sistemi dönüştürmekte zorlandığı vurgulanmıştır.

Published: January 2022

A simple new method for efficient self-immobilization of plant cells has been developed based on the natural cell tendency to aggregate. By this method tight cell beads of up to several mm in diameter can be grown. – The cell lines of correa arabica and Nicotina tabacum
growing in such beads were used in a specially designed expanded-bed reactor. A separate oxygenation vessel in the medium circulation loop was used to eliminate the shear stress caused by direct aeration. – High cell densities and an excellent growth rate of the aggregates in the reactor
comparable to the best shake-flask experiments was achieved, however, the production of secondary metabolites (alkaloids) was very low. Therefore, the expanded-bed reactor can be employed advantageously for biomass production in a first stage of a plant cell reactor system.

Study of an asynchronously rotating polar CD Ind
Authors: Joshi Arti , Pandey Jeewan Chandra
Published: January 2022

We present X-ray and ultaviolet (UV) analyses of the magnetic cataclysmic variable CD Ind. The X-ray light curves obtained from different observations show a very chaotic and spectacular pattern. X-ray and UV variations occur at orbital periods of (124.0±0.4) and (112.3±0.4) min and spin periods of (119.4±0.4) and (109.8±0.3) min, respectively. The degree of asynchronism of CD Ind is calculated as ~ 2.2% and ~ 3.7% from the UV and X-ray data, respectively. The variable shape of the X-ray and UV light curves indicate that the geometry of accretion changes in every epoch of observations. A two-pole accretion mode geometry is also visible in the X-ray and UV light curves of CD Ind. This two-pole accretion geometry is supported by the presence of double humps or dips in their X-ray and UV light curves. The rotational modulations of UV data are also found to be anti-correlated with respect to the X-rays, revealing that the UV pulsations are not originating in the region of magnetically confined accretion flow. Unlike other magnetic CVs, a strong fluorescent Ni Kα emission line is detected for the first time in the X-ray spectra of CD Ind. The X-ray and UV variations of CD Ind support the view that this system belongs to the class of asynchronous polars.
Prospects for radio observations of Particle-Accelerating Colliding-Wind Binaries with the Giant Metrewave Radio Telescope
Authors: De Becker Michaël , Ishwara-Chandra C. H. , Benaglia Paula
Published: January 2022

Synchrotron radiation identified in the radio domain for several tens of binary systems made of massive stars provides compelling evidence that a particle acceleration process is at work in these objects, hence their Particle-Accelerating Colliding-Wind Binaries (PACWB) status. Measurements of the synchrotron radio emission allow to investigate the non-thermal physics and to derive some of their properties. Non-thermal spectra are known to increase at lower frequencies, while thermal ones increase toward higher frequencies. In this context, it is worth investigating the expectations from longer wavelengths such as those measured by the Giant Metrewave Radio Telescope in India, in complementarity with the most abundant measurements at centimetric wavelengths obtained with other radio observatories such as the VLA or ATCA.

Published: January 2022

We present the photometric analysis of three short-period eclipsing binaries (EBs), which have been monitored through the 1.3-m Devasthal Fast Optical Telescope (DFOT), Nainital. The two sources 2MASS J152450+245943, 2MASS J163321+543928 were observed in the B, V and Ic- band with 2k×2k CCD and the third source CRTS J163720+172047 was observed with 512×512 CCD in V, Rc and Ic-band. All three systems are found to be double contact eclipsing binaries. The PHOEBE software based on the Wilson-Devinney (WD) code is used for the analysis of the photometric light curves. The mass ratios are found to be 0.97, 0.75 and 0.81 for 2MASS J152450+245943, 2MASS J163321+543928 and CRTS J163720+172047, respectively. The orbital inclinations are estimated to be ~ 74.5o, ~ 49.3o and ~ 60.0o for 2MASS J152450+245943, 2MASS J163321+543928 and CRTS J163720+172047, respectively.

We present UBVRcIc photometry of stars, down to the 20th magnitude, in the region of the intermediate-age open cluster NGC 381. The core and the cluster radii are estimated to be 2.99 ± 0.93 and 5.6 ± 0.1 arcmin, respectively. A total of 350 probable cluster member stars are identified by using proper motion from GAIA as the criterion of membership. The mean proper motion of the cluster is ūx = 1.55 ± 0.38 mas yr-1, ūy = -2.19 ± 0.39 mas yr-1. We notice an anomalous reddening as the optical total-to-selective extinction ratio in the direction of the cluster Rcluster = 3.7 ± 0.1. The reddening E(BV) = 0.35 ± 0.04 mag is found in the direction of the cluster NGC 381. The distance to the cluster is 957 ± 93 pc and the cluster has an estimated age of log(Age)=8.50 ± 0.05 years.

Published: January 2022

C’est au début des années 1950, bien avant qu’il ne soit question de changement climatique, que l’Université de Liège a réalisé ses premières mesures atmosphériques à la station scientifique internationale du Jungfraujoch, dans les Alpes bernoises. Ces observations pionnières ont alors notamment permis de confirmer la présence de méthane et de monoxyde de carbone dans l’atmosphère non polluée prévalant à ce site. Ravivé au milieu des années 1970 par les premières inquiétudes relatives à la destruction de l’ozone stratosphérique, le programme de surveillance n’a depuis plus cessé de fournir des données essentielles à la caractérisation de notre atmosphère et aux changements qu’elle subit sous l’influence des activités humaines ou de phénomènes naturels d’ampleur. Dans cet article, nous présentons quelques résultats déduits récemment de ce programme de longue haleine, pertinents pour la vérification de traités environnementaux internationaux.
Integrated Coastal Zone Management (ICZM) Framework and Ecosystem Approach: eutrophication phenomenon at the Mediterranean Sea
Authors: Kies Fátima , Monge-Ganuzas Manuel , De los Rios Patricio , Elegbede Isa O. , Corselli Cesare
Published: January 2022

The Mediterranean environment stressors and their effect on trophic state require the assessment of interconnection between land-based drivers, the real and potential pressures and impacts. To achieve this, it is necessary to consider as well, several social and economic factors that may influence decision-making around land-sea planning and the management of nutrient, pollutants and sediment transport. Moreover, once the ecological situation is characterized, it is advisable to establish the linking between the natural systems and the ecosystem services. In the Mediterranean Sea, it fairly demonstrated by ecosystem-based management approaches and the literature that human activities can affect the water column, the seafloor, and the biodiversity, among others. Moreover, it is a fact that these issues require a detailed piece of knowledge of a wide variety of geological, sociological, economical and biological variables, among others. Those variables are dependent on prioritises actions. One of them is the monitoring, mitigation and control of the eutrophication processes, which needs the deconstruction of the Integrated Coastal Zones Management (ICZM) approach into priorities actions, in accordance with the multi-level water characteristics and their interconnection, i.e., the coastal zone dynamics, and the multilevel governance.

Quantifying the effects of spatial patterns of green spaces on urban climate and urban heat island in a semi-arid climate
Authors: Gherraz Halima , Guechi Imen , Alkama Djamel
Published: January 2022

Green spaces in urban areas have a positive effect on the urban climate and microclimate. They help regulate the urban climate and mitigate the urban heat island (UHI) by creating a cooling effect through shade and evapotranspiration. In addition, they release oxygen, absorb carbon dioxide, generate shade, as well as energy usage and pollution emissions. The aim of this study is to assess the impact of spatiotemporal changes in green cover on the urban climate to mitigate the urban heat island (UHI). This is achieved through analyzing their effects on the land surface temperature (LST) due to the change in the spatial configuration of this green cover in the period between 1990 and 2019 in Constantine city. To materialize this effect, Google Earth Pro images, Landsat 5TM and Landsat 8 OLI/TIRS images of multiple years were acquired, processed and analyzed to generate land use maps (LU/LC), the normalized difference vegetation index (NDVI) maps. Those maps were used in order to estimate land surface temperature LST, the green cooling island (GCI) and the urban cooling island (UCI) of vegetation. Many landscape metrics (PLAND, CA, PD, NP, LPI, LSI, MPS, AI, PR, and SHAPE_MN) were chosen for the study at the class and landscape level to analyze the relationship between spatial patterns of vegetation and spatial distribution of LST through the SPSS 26 software. Our results showed that there is a negative relationship between NDVI and LST during the study period. Thus, the increase in NDVI values caused a decrease in LST values. Dense green space with the highest values of NDVI had the highest cooling effect. Therefore, our study confirmed that the type, density, size and the shape of vegetation are important factors in determining its cooling effect. The obtained results showed also that a simple, homogeneous and aggregated green landscape is more effective. The large dominant green patch has the highest impact on LST distribution leading to fragmented green patches with complicated shapes which led to an increase in LST.

Published: January 2022

Introduction. In the Comoros archipelago, as in many places in Africa, traditional medicine is the first reflex people have when it comes to finding a cure. This work illustrates the diversity of remedies found in this group of islands. The plant species potentially effective from a pharmaceutical point of view can be targeted through the comparison of different databases. The present study also illustrates the importance of preventing the loss of traditional knowledge based on hundreds of years of observations. Literature. The information in this paper originates from databases built by ethnobotanists as well as peer reviewed scientific articles. In addition, some information also come from work done by locals working with recognized organisms. Conclusions. The scientific literature cites 207 different species that are used for traditional practices in the Comoros archipelago, among which 9 are endemic. These species were compared to the pharmacopoeias of other islands and surroundings from the Indian Ocean in terms of similarities and differences between targeted ailments. Only 3% of the cited species present similarities in use among the islands of the Indian Ocean and surroundings.
Growth and yield performance of Vigna radiata (L.) R.Wilczek influenced by altitude, nitrogen dose, planting pattern and time of sowing under sole and intercropping with maize
Authors: Arshad Muhammad , Ahmad Sajjad , Shah Ghulam Abbas , Nawaz Rab , Ali Shaukat
Published: January 2022

Description of the subject. Mungbean (Vigna radiata [L]. R.Wilczek) is an important summer leguminous crop. It is widely grown in South Asia to fulfill the human nutritious demand of protein, minerals, vitamins and bioactive constituents. It is well suited to be intercropped with cereals in N limited soil to enhance crop productivity through biological nitrogen fixation. Objectives. This paper assesses the impacts of altitude, nitrogen dose, planting pattern and time of sowing on growth and yield parameters of mungbean intercropped with maize in comparison to their sole counterpart. Method. Three-year experiments (2015, 2016 & 2017) were conducted to assess growth and yield performance of mungbean and maize under different environmental conditions and management practices including altitude (1,500; 1,800 and 2,200 m), nitrogen dose (28, 56, 113 kg·ha-1), planting pattern (alternate single row and alternate double row), cropping systems (sole and intercropping), and sowing time of intercropping with maize (simultaneous and staggered). Sole plots of maize and mungbean were also established separately. A Randomized Complete Block Design was used with three replicates. Growth and yield components of mungbean i.e., plant height, leaf area per plant, thousands grain weight, grain yield, biological yield and harvest index were measured. Maize plants were sampled at maturity for computing its grain yield. Results. Orthogonal contrast analysis showed a significant variation in plant height due to year and altitude, leaf area per plant due to intercropping, year and altitude, thousands grain weight due to intercropping, planting pattern and time of intercropping with maize, grain yield due to intercropping, year, altitude and planting pattern, biological yield due to year, altitude and planting pattern, and harvest index due to year and altitude. Moreover, intercropping and management practices influenced maize grain yield. Conclusions. Intercropping reduced the growth and yield performance of mungbean compared to monocropping that is attributed to the competition of resources between two crops. However, this interspecific competition has been mollified at lower altitudes when staggered sowing of mungbean intercropped with maize through alternative double row pattern was done. Consequently, in these conditions mungbean growth and yield was improved.
The emergence of agroecological practices on agropastoral dairy farms in the face of changing demand from dairies
Authors: Vidal Arielle , Lurette Amandine , Nozières-Petit Marie-Odile , Vall Éric , Moulin Charles-Henri
Published: January 2022

Description of the subject. Today, the dairy sector is facing economic, social and environmental challenges. Agroecology seems to be one way of meeting those challenges. However, dairy market demand in terms of volume and supply periods may not be in line with an agroecological transition. Breeders must respond to the production conditions fixed by dairies. Objectives. We analyzed to what extent dairy farming practices are changing in two agropastoral territories after a change in the dairy process or supply period, and whether changes in practices induce a stronger uptake of agroecological practices or, on the contrary, a shift towards more conventional intensification of those practices. We were thus able to see if and how these livestock farming system dynamics contribute to and fashion agroecological transition in dairy production, in response to changes in local contexts. Method. To highlight the evolution of breeders' practices, we interviewed 41 dairy ewe farmers in the South of France and dairy cattle farmers in Western Burkina Faso. We then proposed a normative approach to evaluate to what extent changes in practices corresponded to an agroecological transition. For that purpose, we proposed a grid to analyze local practices in combination with agroecological principles. We evaluated practices before and after changes to the supply period or the dairy market. Results. In each of the territories studied, four trajectories emerged, some of which were part of an agroecological transition. The results showed that the market plays an important role as a driver of transition, in particular in situations of organic production, or limited access to inputs. Other drivers, such as resource management schemes, lead to changes in practices on rangelands towards a reduced use of pastoral resources. Conclusions. In these highly contrasting contexts with different issues, such as food security and land accessibility, farmers bring into play practices according to agroecological principles that appear to respond to the local situation.
Palabres autour des arbres : des discours sur leur intelligence aux dérives de l’anthropomorphisme
Authors: Doucet Jean-Louis
Published: January 2022

L’intelligence des arbres est un sujet qui passionne les populations urbaines. Elle fait l’objet d’un débat animé entre les différents acteurs du secteur forestier. La présente note vise à objectiver ce débat en synthétisant les connaissances récentes sur le sujet. Elle montre que les arbres peuvent communiquer entre eux, soit via des molécules volatiles, soit via des échanges souterrains, notamment grâce à un réseau mycorhizien. Les arbres peuvent aussi percevoir la lumière et les sons. Ils peuvent donc s’adapter à un environnement changeant, ce qui traduit une certaine forme d’intelligence. Néanmoins, renoncer à l’exploitation du bois sur cette base ne peut être justifié. Cela se traduirait par des impacts environnementaux dont la portée est occultée par les détracteurs de l’exploitation forestière.

Description du sujet. Déterminer les conditions optimales d’utilisation des effluents de brasserie en production de phytoplancton. Objectifs. Déterminer le potentiel nutritif, les conditions d’utilisation et la dépollution réalisée suite à l’utilisation d’effluents de brasserie en aquaculture. Méthode. Le surnageant a été analysé. Ensuite, cinq traitements ont été ensemencés de Scenedesmus quadricauda et suivis (biomasses et paramètres physico-chimiques) pendant 27 jours. Finalement, les taux d’abattements des charges polluantes initiales ont été déterminés. Résultats. Le surnageant n’est pas conforme à la norme béninoise, mais présente un potentiel nutritif élevé. La non-neutralisation du pH, initialement acide, occasionne un démarrage tardif de la croissance algale. Le traitement à 10 % présente la production maximale et d’importants abattements de charges polluantes. Conclusions. Dans un contexte où il n’y a pas de station d’épuration fonctionnelle, il serait intéressant d’envisager un partenariat gagnant-gagnant entre les brasseries et les pisciculteurs. Les conditions optimales d’utilisation incluent une dose optimale et une neutralisation préalable du pH.
BiRDS - Binding Residue Detection from Protein Sequences using Deep ResNets
Authors: Chelur Vineeth , Priyakumar U. Deva
Published: January 2022

Protein-drug interactions play important roles in many biological processes and therapeutics. Prediction of the active binding site of a protein helps discover and optimise these interactions leading to the design of better ligand molecules. The tertiary structure of a protein determines the binding sites available to the drug molecule. A quick and accurate prediction of the binding site from sequence alone without utilising the three-dimensional structure is challenging. Deep Learning has been used in a variety of biochemical tasks and has been hugely successful. In this paper, a Residual Neural Network (leveraging skip connections) is implemented to predict a protein's most active binding site. An Annotated Database of Druggable Binding Sites from the Protein DataBank, sc-PDB, is used for training the network. Features extracted from the Multiple Sequence Alignments (MSAs) of the protein generated using DeepMSA, such as Position-Specific Scoring Matrix (PSSM), Secondary Structure (SS3), and Relative Solvent Accessibility (RSA), are provided as input to the network. A weighted binary cross-entropy loss function is used to counter the substantial imbalance in the two classes of binding and non-binding residues. The network performs very well on single-chain proteins, providing a pocket that has good interactions with a ligand.

Xanthene derivatives are organic dyes, some of which are routinely used in different chemical and biological applications, including human medicine. In this work, we investigated the photochemistry of some of the most common ones, fluorescein, eosin Y, and rose bengal, and major products of their photodegradation using optical spectroscopy, NMR, chromatography and mass spectroscopy techniques. These substances, usually considered (photo)chemically stable, were found to liberate carbon monoxide (CO) in 40–80% chemical yields upon extensive irradiation with visible light in aqueous solutions during their multistep concomitant degradation processes. In addition, a number of low-mass secondary photoproducts, such as phthalic and formic acids, were identified in the irradiated mixtures. We demonstrate that these common fluorescent dyes can also be considered as visible-light activatable carbon monoxide (CO)-releasing molecules (photoCORMs) under specific conditions with potential biological implications.

Barishal has recently gone through intense land use and land cover changes (LULC). This study aims to assess the changes of land use of Barishal, which were surveyed from 2000 to 2020 by utilizing Landsat TM, ETM + & OLI-TIRS imageries. The ArcGIS-10.4 & the ERDAS-14 Imagine software were used to deal with satellite images and surveyed measurable data for land cover change evaluation of the study area. Both pre- and post-classification change detection scenarios and NDVI analysis were observed to assess the change result from 2000 to 2020. Maximum likelihood classification was utilized to create unsupervised land cover category (water body, urban, fallow, agriculture, vegetation and lowland). After ensuring acceptable value for each classified image (82.16% for 2020, 76.15% for 2010 & 70.96% for 2000 with Kappa values of 0.64, 0.62 & 0.62 for 2020, 2010 and 2000), a change detection study was performed. This study discovered that the highest growth 69.22% of urban area has been improved within 20 years followed by 49.75% and 21.74% of water bodies, fallow lands; whereas the annual change rate was 14.95%, 7.91% and 10.31% respectively. In contrast, 16.28%, 10.48% and 37.20% of vegetation, agriculture and lowland had been reduced and an (-) annual change rate of 16.03%, 7.15% and 9.99% respectively. In addition, NDVI analysis was also observed a decreasing trend of the vegetation and agricultural lands. The results of this assessment could be supportive to design and appliance significant managing appraisals to protect the agricultural degradation, fruitless urbanization of Barishal district.
Socio-structural Injustice, Racism, and the COVID-19 Pandemic: A Precarious Entanglement among Black Immigrants in Canada
Authors: Mensah Joseph , Williams Christopher J.
Published: January 2022

As several commentators and researchers have noted since late spring 2020, COVID-19 has laid bare the connections between entrenched structurally generated inequalities on one hand, and on the other hand relatively high degrees of susceptibility to contracting COVID-19 on the part of economically marginalized population segments. Far from running along the tracks of race neutrality, studies have demonstrated that the pandemic is affecting Black people more than Whites in the U.S.A. and U.K., where reliable racially-disaggregated data are available. While the situation in Canada seems to follow the same pattern, race-specific data on COVID-19 are hard to come by. At present, there is no federal mandate to collect race-based data on COVID-19, though, in Ontario, at the municipal level, the City of Toronto has been releasing such data. This paper examines the entanglements of race, immigration status and the COVID-19 pandemic in Canada with particular emphasis on Black immigrants and non-immigrants in Toronto, using multiple forms of data pertaining to income, housing, immigration, employment and COVID-19 infections and deaths. Our findings show that the pandemic has had a disproportionate negative impact on Black people and other racialized people in Toronto and, indeed, Canada.
Public Criminology and Media Debates Over Policing
Authors: Schneider Christopher
Published: January 2022

Public criminology is concerned with public understandings of crime and policing and public discussions of such matters by criminologists and allied social scientists. For the purposes of this paper, these professionals are individuals identified by journalists on the basis of academic credentials or university affiliation as those who can speak to crime matters. This qualitative study investigates media statements made by criminologists and allied social scientists following the 2020 murder of George Floyd with two questions in mind: How have they responded to debates over reforming, defunding, and abolishing police? What insight can these responses provide about public criminology more generally? I analyze statements offered by criminologists in news reports and on Twitter using Qualitative Media Analysis, an approach that emphasizes the processes through which discourse is presented to audiences. I argue that recent criminological debates in the media concerning the future of policing have exposed unresolvable tensions among scholars who engage in the practice of public criminology, suggesting that the public is not receiving coherent, authoritative messages about these issues. The findings also raise questions about public criminology and illuminate new concerns regarding scholarly expertise related to knowledge claims and credibility relative to social justice.
Unravelling Discourses on COVID-19, South Asians and Punjabi Canadians
Authors: Das Gupta Tania , Nagpal Sugandha
Published: January 2022

This article uses critical discourse analysis to examine how the higher COVID-19 infection rates among South Asians in general, and Punjabis more specifically, have been represented by conservative politicians and their representatives as a consequence of cultural and religious practices. Two counter-narratives are discussed. The first substitutes the negative image of the Sikh Punjabi Canadian community with a celebratory and positive view of Sikh humanitarianism and community service. The second attributes the high numbers to class attributes such as precarious jobs, poverty-level wages, employment insecurity, lack of sick days, over-crowded housing, racism and lack of access to healthcare. We argue that the conservative explanation as well as the first counter-narrative reveal continuities in culturalist understandings of South Asian immigrants, albeit in slightly different ways. The second counter-narrative represents a discursive resistance by advancing a structural analysis of health and disease in immigrant communities.
