Authors: Kittikowit Santhaya , Suwanabubpa Kittiya , Sithisomwong Sophat
Published: February 2022

Since its economic liberalization in 2012, there has been continuous economic and social development in Myanmar. People, especially city dwellers, are receptive to the foreign and modernized cultures, causing the evolving shift in lifestyle and values. Increase inpurchasing power as a result of higher disposable income including higher personal care and beauty consciousness lead consumers to higher attention to personal care and beauty products. As a result, this industry has been enjoying robust growth. However, most cosmetic products seen in the market are imported from overseas, especially from Thailand. As Yangon is a very promising consumer market, it is consequently rather highly competitive. The researcher was then interested in studying the factors influencing purchase intention of female consumers aged 20-60 years old. The objectives of the study are 1.) to explore the current situation of cosmetic industry in Yangon 2.) to identify factors influencing purchase intention and 3.) to provide recommendations to cosmetics exporters or any interested parties. The research analysis was conducted based on the information from consumer and a business operator interviews as well as the subsequent quantitative data acquired from 315 survey respondents during August -October 2017. According to the research findings, brand, quality and price of a product, including social influence all have influence on purchase intention. Moreover, country of origin also has an influence on perceived quality among consumers. Recommendations based on research result interpretation are to develop value for money products for which quality is the primary focus, to formulate effective branding and marketing strategies deploying social influence as one of the strategic communication channels.

Authors: Takacs J. M. , Boito S.C. , Myoung Y.-C.
Published: February 2022

Catalytic transition metal mediated transformations enable a variety of novel bond constructions and open up exciting new possibilities for synthesis. To date, a relatively limited number of these reactions have been used as key strategy elements in the asymmetric total synthesis of structurally complex natural products. This review examines several recent
applications wherein the subset of transition-metal-catalyzed reactions, metal-catalyzed carbocyclizations, defines the key retrosynthetic transformation in the synthetic plan. The applications chosen and analyzed so as to highlight their efficiency, brevity and intrinsic elegance of design and are placed in context by comparison to complementary classical approaches to the target structure.
Chemical Synthesis of Oligonucleotides by Use of Phenylthio Group
Authors: Sekine Mitsuo , Hata Tsujiaki
Published: February 2022

This review deals with recent studies of oligonucleotide synthesis using the phenylthio group as the phosphate protecting group. Several fundament! properties of the P-S bond in phosphorothioate compounds are described in detail. The chemical synthesis and properties of nucleoside phosphorothioate derivatives, which can be prepared via silyl phosphite intermediates, are described. Several interesting and unique properties of a new useful phosphorylating reagent, S, S-diphenyl phosphorodithioate (PSS) are described with some examples involving an application to oligodeoxyribonucleotide synthesis using the phenylthio group as the 5'-terminal or internucleotidic phosphate protecting group. The potential utility of pyridinium phosphonate (PPN) has been demonstrated as an efficient catalyst for dephenylthiolation of bis(phenylthio)phosphorylated nucleoside derivatives, which is required for stepwise condensation in these oligonucleotide syntheses via the phosphotriester approach. Further application of this thiophosphotriester method to the solid-phase synthesis of oligodeoxyribonucleotides is described. The background of developments of bifunctional condensing reagents such as MDS and DDS and their application to the liquid phase synthesis of oligonucleotides are also reviewed. Several methods using oximate reagents and (Bu3Sn)20
are exemplified for removal of the phenylthio group from fully protected oligonucleotides. The
application of the phenylthio group as an activatable protecting group to the chemical synthesis of 7-methylguanosine (MMG)- and trimethylguanosine (TMG)-capped oligonucleotides. Other applications of this activation strategy to the synthesis of naturally occurring nucleic acids are also described. Finally, a plausible mechanism of the present thiophosphotriester method is discussed.

Authors: Speiser Bernd
Published: February 2022

This review shows some recent developments in the use of electroanalytical methods in the context of organic electrochemistry. Several techniques (cyclic voltammetry, spectroelectrochemistry, electrochemical quartz microgravimetry, and scanning electrochemical microscopy) for elucidation of properties and reactivity of organic compounds and materials
are discussed. Such techniques also allow the detailed analysis of electron transfer initiated chemical reactions. Advantages added by techniques not only recording current-potential-time relationships, but including spectral, mass, and spatial information are pointed out. Thus, structures of redox active or electron transfer generated species become accessible, properties of surface bound and deposited molecules can be determined, and lateral resolution for both, analysis of the chemical nature of electrode surfaces, and induction of reactions on electrodes is provided.
Isolation of Fibroblast Growth Factor Receptor Binding Sequences using Evolved Phage Display Libraries
Authors: McConnell Stephen J. , Thon Vicki J. , Spinella Dominic G.
Published: February 2022

A fusion protein construct consisting of the short form of human fibroblast growth factor (FGFR) fused to the heavy c;hain of mouse lgG1 was used to screen four phage display libraries displaying 8, 13, 38 and 43 amino acids at the amino terminus of the bacteriophage M13 gene Ill minor coat protein. Phage with specific FGFR binding activity were isolated from the 13,
38 and 43mer libraries. One of the highest affinity phage clones from the 13mer library was chosen to be further evolved by oligonucleotide saturation mutagenesis. We have isolated evolved sequences that have approximately 8 times the relative binding affinity of the parent sequence. The phage clones have a m1n1mum consensus sequence of CR/SXLLXGAPFXXXXC, where X represents positions tolerant of several amino acids. A synthetic peptide based on this sequence specifically inhibits FGF from binding to its receptor in an in vitro ELISA
Efficient Computational Algorithms for Docking and for Generating and Matching a Library of Functional Epitopes II. Computer Vision-Based Techniques for the Generation and Utilization of Functional Epitopes
Authors: Nussinov Ruth , Wolfson Haim J.
Published: February 2022

This is the second review in a two-part series. In the first review (1) we described the computational complexity involved in the docking of a ligand onto a receptor surface. In particular, we focused on efficient algorithms designed to handle this computational task. Such a procedure results in a large number of potential, geometrically feasible solutions. The difficulty is to pinpoint which of these is the more likely candidate. While there exists a number of approaches to rank these solutions according to different criteria, such as the size of the interface or some approximation of their binding energetics, none of the existing methods has
been shown to be consistently successful in this endeavor. If the binding site is unknown a
priori, the magnitude of the task is awesome. Here we propose one way of addressing this problem, i.e., via derivation and utilization of binding epitopes. If a library of such epitopes is available, particularly for a large number of protein families, it may be used to predict more likely binding sites for a given ligand. We describe an efficient, computer-vision based method to construct binding epitopes focusing on two ways through which such a library can be generated, (1) molecular surface-based, or (iJ) residue-based. Alternatively, the two can be combined. We further describe how such a library may be used efficiently in the matching/docking procedure.
Application of Homogeneous Time-Resolved Fluorescence (HTRF™) to Monitor Poly-ubiquitination of Wild-type p53
Authors: Yabuki Nami , Watanabe Shin-ichi , Kudoh Tsutomu , Nihira Shin-ichi , Miyamoto Chikara
Published: February 2022

Rapid degradation of wild-type p53 in the human uterine cervix is induced by the infection of high-risk human papilloma virus (HPV) types 16 and 18. HPV-E6 protein plays a critical role in the poly-ubiquitination of wild-type p53 by mediating the association of p53 with E6-associated protein (E6AP). As a result, the poly-ubiquitinated p53 is rapidly and selectively degraded by the 26S proteasome. We have established a high throughput assay system to monitor poly-ubiquitination of wild-type p53 using a new fluorescence homogeneous technology known as Homogeneous Time-Resolved Fluorescence (HTRF™). The Europium Cryptate (Eu(K)]-Iabeled ubiquitins are incorporated into poly-ubiquitin chains conjugated with the biotinylated p53. In the HTRF assay, Europium cryptate-labeled ubiquitin and streptavidin­ labeled allophycocyanin (XL665) are used as the fluorescence donor and acceptor, respectively. The biotinylated p53 is ubiquitinated by ubiquitination enzymes, then by the addition of streptavidin-labeled XL665, the donor and acceptor molecules are brought in close proximity, thereby generating fluorescent signals. This time-resolved fluorescence assay system shows a sufficient signal for its application in synthetic compound screening and having almost
the same level of sensitivity as that monitored by the scintillation proximity assay (SPA) using 1251-
labeled ubiquitin. The detection of poly-ubiquitination of wild-type p53 by using the HTRF™ or SPA systems described here is much easier and quicker than by using conventional methods. Therefore, these new systems would be appropriate for high throughput screening of compounds for the discovery of new inhibitors of poly-ubiquitination of wild-type p53.

Published: February 2022

We had developed a technology for creation of recombinant polyclonal antibody libraries, standardized perpetual mixtures of polyclonal whole antibodies for which the genes are available and can be altered as desired. We report here the first phase of generating a polyclonal antibody library to Cryptosporidium parvum, a protozoan parasite that causes severe disease in AIDS patients, for which there is no effective treatment. BALB/c mice, immunized by neonatal oral infection with oocysts followed by intraperitoneal immunization with a sporozoite/oocyst preparation of C. parvum, were used for construction of a Fab phage display library in a specially­ designed bidirectional vector. This library was selected for reactivity to an oocyst/sporozoite preparation, and was shown to be antigen-specific and diverse. Following mass transfer of the selected variable region gene pairs to appropriate mammalian expression vectors, such anti-C. parvum Fab phage display libraries could be used to develop chimeric polyclonal antibody libraries, with mouse variable regions and human constant regions, for passive immunotherapy of C. parvum infection.
Inhibitors and Activators of the p38 Mitogen-Activated MAP Kinase
(MAPK) Family as Drugs to Treat Cancer and Inflammation
Authors: Denny William A.
Published: February 2022

The p38 MAP kinases are a sub-family of the broad group of mitogen-activated serinethreonine
protein kinases. The best-characterised, most widely expressed, and most targeted by drugs
is p38α MAP kinase. This review briefly summarises the place of p38α MAP kinase in cellular signalling
and discusses the structures and activity profiles of representative examples of the major classes of
inhibitors and activators (both synthetic compounds and natural products) of this enzyme. Primary
screening was direct in vitro inhibition of isolated p38α enzyme.
The Interactions among Hypertension, Cancer, and COVID-19: Perspective with Regard to Ca2+/cAMP Signalling
Authors: Bergantin Leandro Bueno
Published: February 2022

Background:

The hypothesis that hypertension is clinically associated with an enhanced
risk of developing cancer has been highlighted. However, the working principles involved in this link
are still under intensive discussion. A correlation among inflammation, hypertension, and cancer could
accurately describe the clinical link between these diseases. In addition, dyshomeostasis of Ca2+ has
been considered to be involved in both cancer and hypertension, and inflammation. There is a strong
link between Ca2+ signalling, e.g. enhanced Ca2+ signals, and inflammatory outcomes. cAMP also
modulates pro- and anti-inflammatory outcomes; pharmaceuticals, which increase intracellular cAMP
levels, can decrease the production of proinflammatory mediators and enhance the production of antiinflammatory
outcomes.

Objective:

This article highlights the participation of Ca2+/cAMP signalling in the clinical association
among inflammation, hypertension, and an enhanced risk for the development of cancer. In addition,
considering that research on coronavirus disease 2019 (COVID-19) is a rapidly evolving field, this
article also reviews recent reports related to the role of Ca2+ channel blockers in restoring Ca2+ signalling
disruption due to COVID-19, including the relationship among COVID-19, cancer, and hypertension.

Conclusion:

An understanding of the association among these diseases could expand current pharmacotherapy,
involving Ca2+ channel blockers and pharmaceuticals that facilitate a rise in cAMP levels.
Consequences of Antipsychotic Medications on Mental Health
Authors: Bukhari Syed Nasir Abbas
Published: February 2022

Individuals suffering from mental illnesses, unfortunately, have a shorter lifespan. An
increase in mortality rates is primarily due to physical illness, unhealthy lifestyle, and associated
comorbidities. Antipsychotic medications, previously known as tranquilizers, antipsychotics, or
neuroleptics, can alleviate or attenuate symptoms related to psychosis, delusion, and/or hallucinations
and are used in the treatment of psychosis, schizophrenia, bipolar disorder, depression, or
Alzheimer's disease. Within hours to days, these medications alleviate symptoms and reduce confusion
in individuals with psychosis; however, the full effect may take longer than usual in some
cases. Importantly, these drugs do not cure the disease, but only treat the symptoms of the disease.
The treatment is adjusted to reduce any psychotic symptoms while keeping the adverse effects to a
minimum level. Antipsychotics may lead to increased risk of diseases, including but not limited to,
diabetes, obesity, metabolic disorders, cardiovascular, renal, or respiratory disorders. Improved
dosages, polypharmacy, and age-specific treatment play an important role in limiting the comorbidities,
as well as the side effects. Further research and clinical attention are required to understand
the functioning of these medications. The review focuses on the use of antipsychotic medications
in different diseases and their effect on mental health.

Digital and Mobile Health Technology in Collaborative Behavioral Health Care: Scoping Review
Authors: Moon Khatiya , Sobolev Michael , Kane John M
Published: February 2022

Background

The collaborative care model (CoCM) is a well-established system of behavioral health care in primary care settings. There is potential for digital and mobile technology to augment the CoCM to improve access, scalability, efficiency, and clinical outcomes.

Objective

This study aims to conduct a scoping review to synthesize the evidence available on digital and mobile health technology in collaborative care settings.

Methods

This review included cohort and experimental studies of digital and mobile technologies used to augment the CoCM. Studies examining primary care without collaborative care were excluded. A literature search was conducted using 4 electronic databases (MEDLINE, Embase, Web of Science, and Google Scholar). The search results were screened in 2 stages (title and abstract screening, followed by full-text review) by 2 reviewers.

Results

A total of 3982 nonduplicate reports were identified, of which 20 (0.5%) were included in the analysis. Most studies used a combination of novel technologies. The range of digital and mobile health technologies used included mobile apps, websites, web-based platforms, telephone-based interactive voice recordings, and mobile sensor data. None of the identified studies used social media or wearable devices. Studies that measured patient and provider satisfaction reported positive results, although some types of interventions increased provider workload, and engagement was variable. In studies where clinical outcomes were measured (7/20, 35%), there were no differences between groups, or the differences were modest.

Conclusions

The use of digital and mobile health technologies in CoCM is still limited. This study found that technology was most successful when it was integrated into the existing workflow without relying on patient or provider initiative. However, the effect of digital and mobile health on clinical outcomes in CoCM remains unclear and requires additional clinical trials.
The Content, Quality, and Behavior Change Techniques in Nutrition-Themed Mobile Apps for Children in Canada: App Review and Evaluation Study
Authors: Brown Jacqueline Marie , Franco-Arellano Beatriz , Froome Hannah , Siddiqi Amina , Mahmood Amina , Arcand JoAnne
Published: February 2022

Background

Children increasingly use mobile apps. Strategies to increase child engagement with apps include the use of gamification and images that incite fun and interaction, such as food. However, the foods and beverages that children are exposed to while using apps are unknown and may vary by app type.

Objective

The aim of this study is to identify the app content (ie, types of foods and beverages) included in nutrition-themed apps intended for children, to assess the use of game-like features, and to examine app characteristics such as overall quality and behavior change techniques (BCTs).

Methods

This analysis used a cross-sectional database of nutrition-themed apps intended for children (≤12 years), collected between May 2018 and June 2019 from the Apple App Store and Google Play Store (n=259). Apps were classified into four types: food games or nongames that included didactic nutrition guides, habit trackers, and other. Food and beverages were identified in apps and classified into 16 food categories, as recommended (8/16, 50%) and as not recommended (8/16, 50%) by dietary guidelines, and quantified by app type. Binomial logistic regression assessed whether game apps were associated with foods and beverages not recommended by guidelines. App quality, overall and by subscales, was determined using the Mobile App Rating Scale. The BCT Taxonomy was used to classify the different behavioral techniques that were identified in a subsample of apps (124/259, 47.9%).

Results

A total of 259 apps displayed a median of 6 (IQR 3) foods and beverages. Moreover, 62.5% (162/259) of apps were classified as food games, 27.4% (71/259) as didactic nutrition guides, 6.6% (17/259) as habit trackers, and 3.5% (9/259) as other. Most apps (198/259, 76.4%) displayed at least one food or beverage that was not recommended by the dietary guidelines. Food game apps were almost 3 times more likely to display food and beverages not recommended by the guidelines compared with nongame apps (β=2.8; P<.001). The overall app quality was moderate, with a median Mobile App Rating Scale score of 3.6 (IQR 0.7). Functionality was the subscale with the highest score (median 4, IQR 0.3). Nutrition guides were more likely to be educational and contain informative content on healthy eating (score 3.7), compared with the other app types, although they also scored significantly lower in engagement (score 2.3). Most apps (105/124, 84.7%) displayed at least one BCT, with the most common BCT being information about health consequences.

Conclusions

Findings suggest nutrition-themed apps intended for children displayed food and beverage content not recommended by dietary guidelines, with gaming apps more likely to display not recommended foods than their nongame counterparts. Many apps have a moderate app quality, and the use of consequences (instead of rewards) was the most common BCT.
eHealth in Norway Before and After the COVID-19 Pandemic
Authors: Schopf Thomas
Published: February 2022

Background

Regular teledermatology services were implemented in Norway in the early 1990s. Based on the available technology at the time, live interactive video consultation systems were implemented to facilitate remote consultations between dermatologists and general practitioners. With the introduction of digital cameras some years later, store-and-forward systems were introduced, but the live video systems remained popular. In the 2000s and early 2010s, there were few changes in the volume of Norwegian teledermatology services. During the 2010s, private teledermatology companies emerged, which provided both store-and-forward and live interactive video consultations. While previous services involved specialists and general practitioners, the new services now offered to patients enable them to interact with dermatologists directly.

Objective

This lecture aimed to provide a brief overview of the development of telemedicine in Norway before and during the COVID-19 pandemic with special focus on teledermatology.

Methods

This lecture provides a brief history of telemedicine in Norway with special attention to the impact of the ongoing COVID-19 pandemic. The content is based on personal experiences and literature references.

Results

The COVID-19 pandemic has had a profound impact on all parts of society. In Norway, it has also affected the way telemedicine is practiced. When the number of new infections increased substantially in early 2020, Norway was under lockdown. This had major consequences on the health care system. In response, the Norwegian government and health authorities strongly encouraged the use of telemedicine and implemented measures to support its use. Since then, there has been a large increase in the number of live video consultations both in specialist and community health care.

Conclusions

When the necessary technical infrastructure is in place, the remaining barriers to telemedicine use, such as reimbursement and integration of health care systems, can easily be overcome, which would result in high adoption rates of telemedicine.

Rehabilitation and Resettlement Policy and its Implementation: A Case Study of Indira Sagar Project in Andhra Pradesh, India
Authors: Kumar K. Anil , Chikkala Nagaraju
Published: February 2022

After Independence to achieve rapid economic growth India has invested in various development projects to create new infrastructure. This has been made possible through massive acquisition of land for various development projects in the country. Development projects, such as hydropower, irrigation dams or mines, trigger forced population displacement. Number of people who have been displaced due to development projects are between 60-65 million. Of these displaced, over 50% are tribals. The High Level Tribal Committee Report 2014 reveals that tribal people are the worst sufferers by development projects, when compared to others. It is largely this group that is paying for the development of India. A majority of the displaced people have not been properly resettled or given adequate compensation. Improper implementation of rehabilitation and resettlement policy fail to resettle people sustainably and instead cause their impoverishment. With the above backdrop, the present paper discusses the issues related to implementation of rehabilitation and resettlement policy in India and united Andhra Pradesh. The paper also makes an attempt to assess and evaluate the implementation of the rehabilitation and resettlement policy of Indira Sagar project. It is an empirical study of Indira Sagar Project in Andhra Pradesh. In-depth interviews and focus group discussions tools were used to collect data from displaced community and with government officials. Research findings revealed various impacts experienced by households economically and socially.
Role of Emotional Intelligence and Coping in Dealing with Disinhibition and Aggression among Undergraduates in Private Higher Education
Authors: Khawaja Sarwar , Qureshi Fayyaz H , Soki? Katarina
Published: February 2022

This research examined the relationship between emotional intelligence and coping, disinhibition and aggression. Additionally, coping was examined as a potential mediator of the relationship between emotional intelligence, disinhibition and aggression. Participants consisted of 563 students (186 men, 377 women) from various private colleges and faculties. The participants’ age ranged from 19 to 30, with a mean age of 23 years (M = 23.2, SD = 4.23). As predicted, disinhibition was uniquely negatively associated with self-emotion appraisal, others’ emotion appraisal, use of emotion, regulation of emotion and coping. Also, as predicted, aggression was uniquely negatively associated with the regulation of emotion and coping, suggesting that disinhibition and aggression in a coherent fashion influence emotional intelligence and coping. Additionally, coping mediate the relationships between disinhibition and self-emotion appraisal, use of emotion, and regulation of emotion as well as relationships between aggression and these dimensions of emotional intelligence. The results demonstrate that disinhibition and aggression negatively affect emotional intelligence and coping. The results of mediation analyses corroborated the relationships between disinhibition, aggression and emotional intelligence and the role of coping as its mediator, highlighting the importance of disinhibition and aggression in the prediction of some dimensions of emotional intelligence and the significant role of coping as a mediator in these relationships.
Review on Network Security Using Machine Learning Algorithms
Authors: Yasotha K. , Sundaram Dr. K. Meenakshi
Published: February 2022

Abstract: Today various real world applications network such as VANETs, MANETs, and WSNs supply a wide range of applications from security to infotainment. As the communication and network field has linked faraway corners of the world using advanced network technology, intruders, hackers or attackers have also raised attacks on networking infrastructure as in enough. Administrators can need to prevent such hacks by using advanced intrusion detection tools. The use of resources, loss of packs, and justice are common performance measures for network based applications, which are usually required by network safety applications to reduce transmission time and to achieve high reliability. The performance of the overall unit is decided by two logics, one is security and another one is privacy. To maintain such data secured architectures, Intrusion Detection System (IDS) is the most commonly used mechanism to detect the attacks on cloud. Hence, more number of researchers focused on this topic. To overcome the limitations of earlier IDS approaches and an elaborate comparison of machine learning based IDS in terms of factors efficiency, execution/detection time, flexibility and true/false rate.

The influence of foams, having different expansion ratios, on the structurization of thermal insulation foam concrete
Authors: Vinokurova Ol’ga V. , Baranova Albina A.
Published: February 2022

Introduction. The article addresses the influence of foams, having different origins and expansion ratios, on the structurization of thermal insulation foam concrete. The study is focused on solving the problem of the binder hydration conditions in the interpore space of the foam concrete mixture and maintaining its stability. The goal is to design an economically effective composition. Materials and methods. To analyze the structurization process, foam concrete samples, featuring average density grades D300 and D500, were made using ordinary Portland cement. The nature of the surfactant substance of the foam, its expansion ratio and the water-cement ratio of the solution are the variable factors determining parameters of the material structure. The strength of the foam concrete was used to evaluate the cement hydration conditions. The strength was identified according to GOST 10180. Parameters of the macrostructure were measured using the Levenhuk optical microscope and the LevenhukLite software. Results. It is found that hydration in the interpore space of the mixture is implemented to the fullest extent when a protein foaming agent, featuring a low foam expansion ratio, is used. The foam concrete, thus made, has closed pores, whose diameter varies in a small range of values, while the partition thickness exceeds the maximum size of the cement grain. An increase in the foam expansion ratio and a low value of the water-cement ratio of the solution lead to the uneven distribution of air in the mixture and reduce the thickness of the interpore partition. In this case, the structure of the foam concrete is “friable”; it represents conglomerates of interconnected pores. Conclusions. Since the geometry of the macrostructure of the material has a significant influence on the heat transfer process and strength, the protein foaming agent, featuring a low foam expansion ratio, is preferable for the production of thermal insulation foam concrete using standard Portland cement without re-grinding. Otherwise, a higher foam expansion ratio foam requires an increase in the specific surface area of the binder.

Authors: Griffith Jane
Published: February 2022

Background: Though initial construction began on a colonial boarding school for Indigenous students, known as an Indian boarding school, in Medicine Hat in 1890, the school never ended up opening due to underfunding by the federal government.

Analysis: Informed by Indigenous studies scholarship on place and media, this article uncovers archival traces of this unbuilt environment to reveal how white settlers used newspapers as well as visual media to will the school into being, particularly with techniques of re-placement on stolen Indigenous land.

Conclusion and implications: This article connects the history of the school that never opened with the present day, insisting on the ongoingness of settler colonial tactics in media.
Sustainability or protectionism in palm oil trade: The case (DS593) of Indonesia vs. the EU
Authors:   Deree College – The American College of Greece, Greece, Radmann Barbara Margarita
Published: February 2022

Abstract: This paper examines the case DS593 to understand whether the developments in question represent an attempt to further well-justified policy objectives relating to sustainability or represent protectionism in disguise. DS593 came as Indonesia’s reaction to the EU Renewable Energy Directive II (RED II) that limits and bans palm-oil imports for the “foreseeable future”. Indonesia’s strong economic dependence on palm oil exports led it to look at the justification of RED II critically and thus to highlight some inconsist- encies. These inconsistencies center around the EU’s definition of high and low Indirect Land Use Change (ILUC) risk biofuels. A review of already existing literature on the subject, in combination with the actual WTO agreements were studied to query the issue. It is argued that further deliberation is needed on the side of the EU on what constitutes high or low ILUC risk and on other biofuels apart from palm-oil which are considered unsustainable for EU regulations to not be considered protectionist. Keywords: biomass fuel, palm-oil, WTO, international trade. JEL Classification: Q2, Q270.

Abstract: Technological development has resulted in the digitization of many areas of life. The modern society is particularly defined as the “information society”, because of the fact that most of their activities take place on the Internet and thus the society is information-dependent. The introduced governmental sanitary restrictions (also in terms of the functioning of the economy) to limit the spread of the coronavirus caused that life has shifted to a greater extent to the Internet sphere. The aim of the study is to determine the potential impact of a pandemic on the virtualization of buying behavior. The con- ducted research is exploratory in nature and constitutes a valuable starting point for po- tential further directions of analyzes. The results of this study showed that excavating the topic of the impact of the pandemic on buying behavior in the area of consumption vir- tualization is justified, because in all the analyzed product categories there was a statisti- cally significant change in the form of purchases. Keywords: virtualization, buying behavior, customer behavior, pandemic, COVID-19. JEL Classification: D10, D12, E21

Published: February 2022

O presente ensaio trata de questões inerentes à construção do tempo e da memória nas crônicas do escritor português contemporâneo António Lobo Antunes. É sabido que, epistemologicamente,  esse gênero literário é constituído a partir da gênese do seu nome (crônica – chronos/kairós) e, desse viés temático, este trabalho busca mostrar como a memória e o tempo permeiam o vivido e o imaginado, como o encontro imagético entre avô e neto, num futuro construído por memórias.

Individual corrupt behavior: An experimental analysis of the influence factors personality and gender
Authors: Ulrich Patrick , Behringer Stefan , Unruh Anjuli , Frank Vanessa
Published: February 2022

There is no clarity in the literature on the extent to which the personality and gender factors influence the propensity of individual employees to engage in corruption. This topic is gaining importance not only in theory but also in practice due to increasing scandals and violations of regulations. In this paper, the influence of personality and gender on corruption propensity and corrupt behavior is investigated using an experimental design of 2×2 groups. A study of 134 students from different universities in 2020 served as the sample. It was found that there are significant differences in corruption propensity and corrupt behavior between subjects. The case underlying the experiment involved a company where the subjects of the experiment worked. As a result, they were asked by the CEO of the company to hand over a suitcase of money containing bribes. It was found that women showed a higher degree of conscientiousness than men, but a significantly lower propensity to corruption overall than the male subjects.

Objective To assess whether the subendometrial blood flow condition
detected by Doppler ultrasound could predict pregnancy outcomes in
patients with thin endometrium during in vitro fertilization (IVF)
treatment. Design Retrospective cohort study. Setting Reproductive
Hospital affiliated with Shandong University, Jinan, Shandong, China
Population or Sample The study included 3830 frozen embryo transfer
(FET) cycles of 3,830 IVF patients between January 2017 to December
2019. Methods Endometrial thickness, endometrial blood flow, and
subendometrial blood flow were measured using transvaginal color Doppler
ultrasound, evaluated by experienced clinical ultrasound physicians on
the day of endometrial transformation. Logistic binary regression was
used to analyze the effects of subendometrial blood flow on successful
embryo implantation. Pregnancy outcomes of these patients were
documented in clinic medical records during follow-up. Main Outcome
Measures Pregnancy outcomes (biochemical pregnancy rate, clinical
pregnancy rate and live birth rate) Results A total of 3830 frozen
embryo transfer cycles were retrospectively analyzed. Our results show
that patients with subendometrial blood flow exhibit higher average
success rates of live birth, clinical pregnancy, and embryo implantation
compared to those without subendometrial blood flow when endometrial
thickness is ≤ 0.7 cm. In detail, in thin endometrium patient group, the
presence of subendometrial blood flow is correlated with 7.2% higher
biochemical pregnancy rate, 7.0% higher clinical pregnancy rate, and
6.2% higher live birth rate compared to those without subendometrial
blood flow. Conclusions Endometrial and subendometrial blood flow
conditions have predictive value for pregnancy outcomes after frozen
embryo transfer in patients with thin endometrium
“No sé a dónde se fue el tiempo”: testimonios de estudiantes durante la cuarentena
Authors: Cane Julieta
Published: February 2022

El presente ensayo explora las formas de concebir el tiempo desde diferentes condiciones sociohistóricas. En particular se centra en el contexto de la pandemia por COVID-19 a partir de la lectura de los testimonios de las y los estudiantes de comunicación de universidades argentinas sobre las formas de experimentar el tiempo durante la cuarentena.  Este análisis es producto de la colaboración de la Facultad de Periodismo y Comunicación Social (UNLP) en la investigación interuniversitaria “Cómo se informan y cómo estudian los estudiantes de periodismo de las universidades argentinas a través de dispositivos digitales” (Investigar en Red)[1].

Construyendo inéditos posibles en Educación Ambiental
Authors: Menegaz Adriana , Garcia Daniela
Published: February 2022

En el marco de esta convocatoria de la Revista Question, que nos invita a reflexionar sobre el presente y el porvenir recuperando experiencias, logros o aspectos emergentes durante la pandemia Covid-19, resulta interesante reseñar un trabajo publicado recientemente titulado “Educación Ambiental y Educación Inicial: desafíos e inéditos en el contexto de Pandemia”. En el mismo se realizan lecturas territoriales, paradójicamente emergentes en el contexto de aislamiento social, que posibilitaron repensar y resignificar la enseñanza desde una perspectiva crítica de la Educación Ambiental.

La figura del intelectual en la Argentina del último siglo
Authors: Delupi Baal
Published: February 2022

El presente ensayo tiene por objetivo indagar sobre las manifestaciones intelectuales más resonantes de la Argentina del último siglo. Para ello nos proponemos, en una primera instancia, recuperar las conceptualizaciones tradicionales del intelectual, entendiendo que no se harán todas las distinciones clásicas en términos generales, sino más bien se buscará explicitar aquellas cuestiones relevantes que operan como punto de partida para pensar su dimensión política. En segundo término, trazamos un recorrido diacrónico para mostrar algunas de las publicaciones intelectuales más significativas del siglo XX y principios del XXI en Argentina: Revista Sur, Contorno, Pasado y Presente, Punto de Vista, Controversia, El Ojo Mocho, Grupo Esmeralda, El Club Socialista y Carta Abierta. Este recorrido permitirá ver la manera en que se fueron configurando, en distintas producciones discursivas, diferentes sujetos intelectuales que responden a periodos socio-históricos divergentes.
Prestigio y tecnología
Authors: Oliveros Fortiche Diana Esperanza
Published: February 2022

Este artículo resultado de una investigación doctoral se apoyó en la teoría del consumo estatutario para describir el impacto social de la apropiación de los dispositivos móviles en las prácticas de prestigio y diferenciación de grupos pertenecientes a clases sociales. Respondió al uso de una metodología de corte mixto, valiéndose de técnicas cualitativas de entrevista biográfica a seis personas y cuantitativas y de encuesta realizada a 122 personas.  Entre sus principales resultados se evidenció como las prácticas de emulación alrededor del uso, compra y gasto excesivo en modelos y marcas, así como la necesidad cotidiana de ostentación de estos dispositivos contribuyen a reproducir y naturalizar los órdenes de desigualdad social en contextos de profunda inequidad como la afrontada en Colombia
Álbumes de vida como portales de memorias
Authors: Bracaccini Acevedo Maria
Published: February 2022

En el presente trabajo presento algunas de las preguntas y reflexiones que se desprenden de mi actual plan de doctorado en Antropología en la Universidad Nacional de Córdoba (Arg.). En dicho trabajo busco indagar sobre la construcción y transmisión de memorias en el Sitio Memoria ex D2 ubicado en la ciudad de Córdoba; analizo específicamente las formas de recordar y representar a las personas desaparecidas. En cuanto a la metodología, propongo un acercamiento etnográfico a los significados que evocan uno de los dispositivos museográficos allí presentes para tal fin: los Álbumes de Vida. A través de estos Álbumes, que se exponen en una de las salas del Sitio, podemos acceder a las historias de vida de personas que desaparecieron en la última dictadura militar del país (1976-1983).

A lo largo del artículo ofrezco una reflexión general sobre esos Álbumes de Vida. Mi interés radica en analizar los sentidos que estas materialidades compuestas por historias y objetos de la vida cotidiana, evocan desde el lugar que hoy asumen en un espacio estatal a la consulta de las y los visitantes.
Sostenibilidad social y prácticas periodísticas
Authors: Silva Cantoni Mariana Inés
Published: February 2022

Este artículo propone dar cuenta de la relación existente entre las miradas sobre la sostenibilidad de medios comunitarios, asociadas a paradigmas sociocríticos y la sociología de la producción noticiosa, vinculada originalmente a los estudios funcionalistas de la comunicación. Partimos de la hipótesis de que es posible revisar y problematizar los estudios de rutinas desde miradas alusivas al ejercicio del periodismo de contrainformación.

Desde un enfoque sociocrítico el texto tiene por objetivo describir de qué manera la inserción social y territorial de radio Comunitaria La Lechuza de San Juan, Argentina, sus formas de articulación con la comunidad, con las organizaciones, con otras emisoras o redes del sector y con el Estado influyen sobre las prácticas periodísticas que desarrollan quienes integran la emisora.

La investigación, de carácter cualitativo y de alcance descriptivo-relacional, aborda el objeto desde un enfoque etnográfico, empleando diversas técnicas de registro de la información.

Gran parte del trabajo de campo lo desarrollamos durante el gobierno de la Alianza Cambiemos que representó un importante retroceso en materia de derechos humanos y comunicacionales, en particular, que afectó de manera significativa a los medios comunitarios del país.
