The 2020 Cannabis Referendum: Māori Voter Support, Racialized Policing, and the Criminal Justice System
Authors: Dempster Craig , Norris Adele N
Published: February 2022

In the New Zealand 2020 cannabis referendum, 50.7% of all voters rejected the creation of a legally-regulated cannabis market and instead supported retaining the current prohibitionist policy. Although the referendum failed to pass, a majority of Māori voted in favor of cannabis law reform. This paper suggests that within the Māori community there is a more nuanced appreciation of the impact of policing cannabis. Māori perceive that greater harm is caused by the racialized policing of cannabis than by the usage of it. Following McCreanor, et al. (2014), this paper employs a thematic, content analysis of the New Zealand Herald’s coverage of the 2020 cannabis referendum to investigate the presence of race-based targeting/policing in discussions of the legislation. The results reveal that racial disparities emerged as secondary to framing both the impact of cannabis and the referendum as race-neutral and affecting everyone in society equally. This paper argues that the impact of the policing of this particular drug impacts Māori differently, wherein they bear the brunt of racialized policing. Thus, Māori possess a more sophisticated understanding that warrants consideration because it is inextricably linked to lived experiences of policing that differ from wider social narratives of policing and drug policy in New Zealand.
Humor e identidad como recursos expresivos para la construcción de marca en redes sociales. El caso de Malacara
Authors: Torres Martín José Luis , Castro-Martínez Andrea , Díaz-Morilla Pablo
Published: February 2022

Este trabajo se centra en el caso de Malacara, una cuenta cuya principal actividad se desarrolla en Twitter y que se ha convertido en todo un fenómeno en el panorama español. A través de la entrevista en profundidad a Lucas Melcón, la persona detrás de Malacara, y del análisis de los perfiles sociales de la marca se pretende analizar el discurso humorístico de sus publicaciones, identificar los recursos expresivos, los temas a los que recurre y describir su estrategia comunicativa digital. Los resultados indican el empleo de textos en mayúsculas imitando el habla andaluza y de imágenes de personalidades conocidas, del mundo animal y de la cultura popular como principales particularidades de su discurso, en el que la vida cotidiana y la crítica política y social tienen un gran peso. El éxito de Malacara demuestra que es posible hacer humor en el terreno digital desde la periferia construyendo una voz propia en base a las raíces vernáculas y populares.
Estudio comparativo sobre el potencial del meme como recurso de comunicación política: recepción, usos y significados en estudiantes universitarios (Ecuador-España)
Authors: Tejedor Santiago , Tusa Fernanda , Cervi Laura
Published: February 2022

Esta investigación analiza la percepción del alumnado sobre el meme como una herramienta discursiva y estratégica en el escenario político digital. Para ello se realiza un estudio comparativo entre 178 estudiantes de las carreras de Comunicación y Periodismo de dos universidades públicas como son: Universidad Autónoma de Barcelona (España) y Universidad Técnica de Machala (Ecuador). A nivel metodológico, se aplicó la encuesta como principal técnica de investigación. El artículo permite concluir que la apropiación de significados de un meme de humor político demanda una decodificación específica del formato y la necesidad de conocer los referentes necesarios para comprenderlos, tratando de evitar un conocimiento superficial del hecho político puesto que existe la posibilidad que el estudiante poco informado no alcance a distinguir lo importante de lo banal. Lo que se busca con este tipo de meme es la democratización del debate social frente a los asuntos públicos, sin caer en un efecto de desensibilización. Al término del estudio, se considera que el meme auspicia la generación de contenido, la participación ciudadana, la libertad de expresión y fomenta así una ciudadanía más participativa, una sociedad políticamente más activa.

Authors:   Assistant  Professor, Department of Anaesthesia, UCMS & GTB Hospital, Delhi, India, Gupta Vibhor
Published: February 2022

Background and Objective: Various risk factors have been evaluated to predict the mortality associated with COVID-19. We aim to explore and compare the clinical and laboratory risk factors with various outcomes of the disease between survivors and non-survivors amongst patients with moderate to severe COVID-19 disease. Methods: All COVID-19 adult (≥ 18 years old) ICU in-patients with a definite outcome i.e. either death or discharge were included. The demographic, clinical, laboratory, treatment, and outcome data were retrieved. To explore the association between factors, univariate and multivariate logistic regression were done. Results: A total of 163 patients were included out of which eight patients were shifted to other hospitals. Finally, a total of 145 patients were included in the study. Out of 145, 47 patients didn’t survive and 98 survived. A significant proportion (85%) of non-survivors were current smokers and were observed to have COPD, HT, and CAD as comorbidities when compared to the survivors. The qSOFA score, CRP, and TLC counts were included in the multivariable logistic regression with the former being the independent risk factor. Interpretation and Conclusion: Our study highlighted that older age, higher SOFA score, increased levels of total leucocyte count, and C-Reactive protein were independent risk factors affecting the clinical outcome in moderate to severe COVID-19 patients; however, qSOFA was found to be an independent risk factor predictor.
Simultaneous Occurrence of Pneumomediastinum, Pneumopericardium and Surgical Emphysema in a Patient of COVID-19: A Case Report
Authors:   Professor of Medicine & Head, Department of Pulmonary Medicine, Maulana Azad Medical College, New Delhi, India, Kumar Naresh
Published: February 2022

As we enter the third year of the COVID pandemic, the SARS-CoV-2 virus keeps on surprising clinicians globally with atypical manifestations. Spontaneous pneumomediastinum is the accumulation of free air within the mediastinum without any preceding trauma or invasive procedure. Pneumomediastinum has been recently reported in the literature, often with associated mortality and morbidity in COVID-19 patients exposed to positive pressure ventilation due to barotrauma. We report the case of a 47-year-old man admitted for management of infection by the SARS-CoV-2. After one week of in-patient treatment, the patient still had worsening dyspnea. Repeat chest X-ray revealed surgical emphysema in neck and NCCT chest revealed pneumomediastinum and pneumopericardium. The spontaneous pneumomediastinum and pneumopericardium with surgical emphysema resorbed over 22 days with a favourable clinical outcome without any invasive intervention. Patient was discharged subsequently with vitals maintaining on room air. A keen clinical observation and timely imaging study can help in detecting these complications early and direct the management accordingly.

Published: February 2022

This paper analyzes the impact of the cancel culture on Karol Conká’s career after participating at brazilian´s TV Globo show called Big Brother Brasil in 2021. Conká was invited to participate as a celebrity and social media influencer to join the reality show and compete for the money prize with non-celebrities. Considering the visibility that the program provides to participants and audience, the research proposes a case study on the transgressions that caused the cancellation of the artist during the period of confinement in the house and the strategies used to reconstruct her public image. This work at Social Communication main field of studies aimed to reference as theoretical concepts digital social media, visibility and digital influencers, to trace a path to the functioning of social networks dynamics. Karol Conká is a justified case study because she was eliminated with the highest rejection rate at Big Brother Brother´s history. The conflicts she was involved in during the show resulted in a loss of thousands followers on Instagram and brought important consequences for her career. As a result, the case study shows that the strategy of silence followed by mental balance narrative was well succeeded to recover audience empathy.
Evolving role of lasers in nail therapeutics
Authors: Dhawan Sachin , Sharma Komal
Published: February 2022

The diseases of nails are chronic disorders due to the slow rate of growth of nails. The slow rate of nail growth results in long treatment regimens, thus having the potential of causing side effects and posing a limitation of administration to many people. Patients who suffer from organ dysfunction, elderly patients, patients under polypharmacy, and the inability of many patients to adhere to the complete regimen can cause the treatment of nail diseases to be frustrating for both the treating dermatologists as well as patients. Most nail disorders have formed a set treatment protocol for the administration of oral and topical drugs over the years. The use of lasers has yet to make its mark in the treatment of nail diseases due to lack of a universally accepted protocol. This review article looks into various studies evaluating the efficacy of lasers in nail diseases. Largely, this review is based on an evaluation of the effectiveness of lasers in onychomycosis (22 studies and 1 meta-analysis) and nail psoriasis (seven studies). While there is sufficient proof that lasers are effective in the treatment of nails, there is no gold standard for the type of lasers to be used for a particular disease, the treatment parameters, and the follow-up protocol. Evaluation of larger sample sizes against a control group and longer follow-ups are the need of the hour for the formulation of much-needed protocols.
Challenges in the Analysis of Gangliosides by LC-MS
Authors: Muggli Thomas , Bühr Claudia , Schürch Stefan
Published: February 2022

Gangliosides are a family of conjugates consisting of a polar sialoglycan head group and a hydrophobic ceramide tail. Gangliosides are of high abundance in neuronal tissues and are involved in numerous biological processes, such as cell-cell recognition, adhesion, and signal transduction. Alteration of the ganglioside profile is associated with various neurodegenerative diseases and there is indication that gangliosides are involved in the pathogenesis of Parkinson’s and Huntington’s disease. The development of refined methods for the analysis of gangliosides by high-performance liquid chromatography coupled to mass spectrometry (HPLC-MS) has supported research with qualitative and quantitative data. However, the amphiphilic character of gangliosides renders their separation and mass spectrometric analysis challenging. In this article, the strengths of hydrophilic interaction liquid chromatography (HILIC) for baseline separation of gangliosides, including two structural isomers, and their structural characterization by tandem mass spectrometry are demonstrated. The importance of ion source parameter optimization is highlighted to prevent misleading ganglioside transformation due to in-source dissociation.
Multi-collector Inductively Coupled Plasma Mass Spectrometry: New Developments and Basic Concepts for High-precision Measurements of Mass-dependent Isotope Signatures
Authors: Greber Nicolas , Van Zuilen Kirsten
Published: February 2022

Due to the development of multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) around 25 years ago, the isotopes of a large range of elements (masses from Li to U) are now analyzed with high enough precision and accuracy to resolve subtle natural variations. These so-called 'non-traditional stable isotope systems' opened many new research avenues and are applied at an increasing rate in research and industry projects and in a broad range of different disciplines, including archeology, biology, physics, cosmochemistry and geology. Here, we briefly summarize the most basic concepts of MC-ICP-MS, introduce new technical developments and address important points on how to acquire accurate high-precision isotope measurements of non-traditional stable isotopes.

Asymmetrical flow field-flow fractionation (AF4) is a powerful technique employed for the separation of macromolecules, nanoparticles, and their assemblages according to their hydrodynamic behavior. It is well known that at this size range, complex interactions can occur between components (e.g. surface adsorption, aggregation) controlling the fate of trace metals (TMs) bound to them. AF4 coupling to inductively coupled plasma mass spectrometry (ICP-MS) allows the quantification of metal-containing species at trace levels present in environmental and biological systems on a size-composition basis. The combination of AF4-ICP-MS with other online detectors provides additional information that allows the assessment of the origin of analytes present in mixtures and complex matrixes with minimal sample preparation, which is crucial for understanding the behavior of trace metal contaminants. Despite the increasing use of AF4-ICP-MS in environmental contexts, we acknowledge that the quantification of inorganic species using such combined techniques requires further development of standardized procedures and need certified reference materials. In this review, we also discuss critical endpoints within the ICP-MS instrument coupled to AF4 that need to be controlled before quantitative measurements can be validated. Then, we illustrate how the combination of different online detectors in addition to ICP-MS offers an integrated picture of natural components states, thus providing key information on the changes in behavior of trace metal species and metallic nanoparticles (MNPs) as observed in both environmental samples and biofluids.

Mass spectrometry is a powerful tool in the hand of life science researchers, who constantly develop and apply new methods for the investigation of biomolecules, such as proteins, peptides, metabolites, lipids, and glycans. In this review, we will discuss the importance of mass spectrometry for the life science sector, with a special focus on the most relevant current applications in the field of proteomics. Moreover, we will comment on the factors that research groups should consider when setting up a mass spectrometry laboratory, and on the fundamental role played by academic core facilities and industrial service providers.
Noble Gas Mass Spectrometry in Earth and Planetary Sciences
Authors: Wieler Rainer
Published: February 2022

Abstract: Noble gases are very rare elements in most relevant samples in geochemistry and cosmochemistry. Noble gases may perhaps also look rather boring to chemists, as they do not form any stable compounds. However, it is just their rarity and chemical inertness which makes noble gases versatile elements in a very wide range of fields, such as oceanography, climatology, environmental sciences, meteorite studies, rock dating, early solar system and early Earth history, and many others. Mass spectrometry is by far the main analytical tool in noble gas geochemistry and cosmochemistry, partly because the rarity of noble gases often allows researchers to recognize in the same sample different noble gas "components" of different origin and hence different isotopic composition. This contribution attempts to illustrate the wide range of applications of noble gas mass spectrometry in the Earth sciences with selected examples.

Published: February 2022

Untargeted metabolomics is now widely recognized as a useful tool for exploring metabolic changes taking place in biological systems under different conditions. In this article, we aim to provide a short overview of the liquid-phase separation methods hyphenated to MS to perform untargeted metabolomics of biological samples. Each approach is complemented by up-to-date literature to guide readers, as well as practical information for avoiding or fixing some of the most frequently encountered pitfalls. This article covers mainly data acquisition, but a short discussion is provided regarding signal processing and data treatment, as well as data analysis and its biological interpretation in the context of metabolomic studies.
Research on IT tools used in flow planning in supply chains
Authors: Jakubiak Michał
Published: February 2022

The processes of globalization and increased competitiveness caused that the company have begun to look for solutions and strategies that give opportunities for development and further market expansion. The intensification of competition on the global scale in the 1980s, forced companies to offer low cost, high quality and robust products with greater design flexibility. Various management concepts have been used to improve production efficiency and speed up the cycle. In the 1990s, many manufacturers and service providers began to focus on improving collaboration with suppliers and improving purchasing and supply management. Initially the cooperation was mainly developed in the area of purchasing policies and supply management in factories, but as time went on, it became increasingly popular among wholesalers and retailers who also decided to integrate their transport and logistics functions in a supply chain with a view to gain competitive advantage (Choon T.). The increase in customer requirements with the same pressures to reduce costs and accelerate time service delivery resulted in the growing importance of planning and anticipation of future events. The increasing amount of data makes management depended on systems that allow for rapid decision-making. Apart from ERP systems, which mainly support the management of individual businesses, more and more companies invest in systems APS (Advanced Planning System), which provide better support in planning processes throughout the supply chain. The aim of the article is to present the idea of advanced supply chain planning, constraints and challenges facing the managing the flow of products and information. The study also addressed the role of Advanced Planning Systems in supply chain management and identify main problems and obstacles that users and decision makers come across while implementing and using IT systems.

Authors: Witczyńska Katarzyna
Published: February 2022

Modern times are associated with a huge increase in the number of security breaches in transnational corporations. The conclusion is that all preventive measures should be taken to stop the growing online crime in globalizing economies. Nowadays, when the Internet is becoming more and more common and more people use its resources, security becomes a priority. The use of firewalls, IDS and IPS systems, the implementation of appropriate security rules, the awareness of network users and the continuous deepening of knowledge in this area can significantly contribute to the security of data of transnational corporations.
The Ability to Restore Railway Traffic on the Route of Jelenia Góra - Karpacz/Kowary
Authors: Haładyn Szymon
Published: February 2022

This article discusses the reason for the suspension of railway traffic on the Jelenia Góra - Karpacz route. The possibility of reactivating the transport on this route was indicated. Based on the equation of the train movement, calculations of the theoretical travel were carried out, as a result of which the technical and total travel time were determined. A rational interval of train runs was determined and a timetable was proposed, taking into account relations going beyond Jelenia Góra. The article justifies the need to introduce supplementary connection operated by electric buses. The concept of reactivating traffic in this area should be supplemented with the construction of a P + R car park. The possibility of further development of the transport system in the discussed area was also proposed.
Automated and Robotic Warehouses: Developments and Research Opportunities
Authors: de Koster René B. M.
Published: February 2022

The first automated, high-bay, warehouses were introduced some 50 years ago. Since then, developments have continued at a rapid pace. Initially, automation was mainly focused on pallet warehouses with bulk storage facilities. A major reason was to increase the storage density, which could be achieved by making the warehouses higher. Later, mini-load warehouses and order picking warehouses were also automated. In this paper we will discuss the different types of automated systems as well as a number of scientific results that are now known about such systems. We will first discuss storage systems for unit loads (bins and pallets). This will be followed by order picking systems from which individual packages can be picked. Finally, we will provide our future expectations of warehouse automation.
Will Transport Affect Globalization? Are We Heading Back to Locally Based Economic Activities?
Authors: Chrzanowski Ignacy H.
Published: February 2022

The paper discusses some aspects of the transport industry’s impact on the process of globalization in the world economy. Emphasis is put on the emerging new trends in that area, and in particular on the reverse globalization frequently referred to as “de-globalization”. While the latter concept provides ground for controversy, it seems that it has become visible in the number of trades and in particular in food trades which engage a considerable portion of the world transport system’s carrying capacity. Moving back to local production of food, one of many areas where the process of de-globalization appears to have started, might liberate vast reserves of transport capacity worldwide while, simultaneously, it will contribute to the reduction of transport-generated pollution. Arguments for such a solution are raised in the paper as is the necessity for more in-depth analysis in this field

Authors: Ćwil Małgorzata Krystyna , Bartnik Witold
Published: February 2022

This paper presents the results of measurements of attitudes towards a demonstrative virtual-reality railway simulator for eco-driving techniques training. This device has been prepared for InnoTrans 2016 railway trade fair, and during this exhibition 144 railway professionals from 35 countries took part in the simulation and filled a questionnaire about their experience and whether they found this type of simulator a viable choice for railway driver training. The results have been very positive with barely any negative answers. This shows that a VR-based railway simulator could potentially be used as a low-cost solution supporting energy efficient train driving.
