Medication nonadherence (MNA) causes severe health ramifications and costs the U.S. healthcare systems $290 billion annually. Understanding patients’ MNA reasons is an urgent goal for researchers, practitioners, and the pharmaceutical industry to mitigate those health and economic consequences. Past years have witnessed soaring patient engagement in social media, making it a cost-efficient and rich information source that can complement prior survey studies and deepen the understanding of MNA. Yet, such a dataset is untapped in existing MNA studies due to technical challenges such as negative decision-making in long texts, varied patient vocabulary, and sparse relevant information. In this work, we develop Sentiment-Enriched DEep Learning (SEDEL) to address these challenges and extract MNA reasons. We evaluate SEDEL on 53,180 reviews of about 180 drugs and achieve a precision of 89.25%, a recall of 88.48%, and an F1 score of 88.86%. SEDEL significantly outperforms the state-of-the-art baseline models. Nine categories of MNA reasons are identified and verified by domain experts. This study contributes to IS research in two aspects. First, we devise a novel deep-learning-based approach for reason mining. Second, our results provide direct implications for the health industry and practitioners to design interventions.
New-Media Advertising and Retail Platform Openness
Authors:   The University of Texas at Dallas, Chen Jianqing , Guo Zhiling ,   Singapore Management University
Published: May 2022

We have recently witnessed two important trends in online retailing: The advent of new media (e.g., social media and search engines) has made advertising affordable for small sellers, and large online retailers (e.g., Amazon and JD.com) have opened their platforms to allow even direct competitors to sell on their platforms. We examine how new-media advertising affects retail platform openness. We develop a game-theoretic model in which a leading retailer, who has both valuation and awareness advantages, and a third-party seller, who sells an identical product, engage in price competition. We find that the availability of relatively low-cost advertising through new media plays a critical role in influencing the leading retailer to open its platform and to form a partnership with the third-party seller, which is impossible when the cost of advertising is relatively high. Low-cost advertising can increase consumer surplus either directly via the third-party seller’s advertising or indirectly via the partnership on the leading retailer’s platform. We also find that the leading retailer has a greater incentive to open its platform and that the partnership is more likely to be formed when there are network effects, when the leading retailer can control the third-party seller’s exposure on its platform, or when the leading retailer can offer a direct advertising service to the third-party seller. Meanwhile, the constraint on the third-party seller’s advertising budget can reduce the leading retailer’s incentive to open its platform, making a partnership less likely. Our analysis offers important insights into the underlying economic incentives that help explain the emerging open retail platform trend in the era of new-media advertising.
When Paying for Reviews Pays Off: The Case of Performance-Contingent Monetary Rewards
Authors:   University of Memphis, Yu Yinan , Khern-am-nuai Warut ,   McGill University, Pinsonneault Alain ,   McGill University
Published: May 2022

Product review platforms in online marketplaces differ with respect to the granularity of product quality information they provide. While some platforms provide a single overall rating for product quality (also referred to as the single-dimensional rating scheme), others provide a separate rating for each individual quality attribute (also referred to as the multidimensional rating scheme). The multidimensional rating scheme is superior to the single-dimensional rating scheme, ceteris paribus, in reducing consumers’ uncertainty about product quality and value. However, we show that, when sellers respond to product ratings by adjusting their prices, compared to the single-dimensional rating scheme, the multidimensional rating scheme does not always benefit consumers, nor does it necessarily benefit sellers or society. The uncertainty associated with quality attribute rating and the extent of differentiation between competing products determines whether a finer-grained multidimensional rating scheme is superior to a coarser-grained single-dimensional rating scheme from the consumer, seller, and social planner perspectives. The main driver of the results is that more (less) granular and less (more) uncertain information exposes (hides) underlying differentiation, or a lack thereof, between competing products, which, in turn, alters upstream price competition in the presence of heterogeneous consumer preferences. The results demonstrate that focusing on the information transfer aspect of rating schemes provides only a partial understanding of the true impacts of rating schemes.
Traceability in Chemical Analysis – What Does that Mean?
Authors: Felber Helene
Published: May 2022

Today, many results of chemical analyses show a poor comparability as can be shown by interlaboratory comparisons. This is partly due to the fact that a widely accepted metrological measurement basis is not yet existing for chemical analysis. Also, in many cases the uncertainty of the
whole analytical procedure is not known. However, due to increasing globalisation, the mutual recognition and thus the reliability and comparability of measurement results is an important issue. Chemists and metrologist worldwide have been working on a concept to achieve comparable results.
The present activities in order to improve comparability of results are described and a concept to achieve traceability to the SI (Système International d'Unités) is presented.

Published: May 2022

The analysis of phosphonic acids in a spiked tap water has been investigated by capillary electrophoresis-mass spectrometry (CE-MS) and liquid chromatography-mass spectrometry (LC-MS) as part of the Third Official Proficiency Test of the Organization for the Prohibition of Chemical Weapons. The use of a non-volatile electrolyte (5 mM sorbic acid/ammonia, pH 6.5) in CE and a volatile mobile phase (water/0.1 v/v trifluoroacetic acid/acetonitrile) in LC achieves the baseline resolution of studied phosphonic acids. Tandem-MS detection analysis allows an accurate identification of these solutes by screening their characteristic fragmentations.

Published: May 2022

Кандидамикозы пищеварительного тракта гусей могут служить причиной нарушения антиоксидантной системы печени, нормальная работа которой обеспечивается витаминами. В этой связи были проведены исследования по определению баланса витаминов в печени, ибо многие из них поступают в организм с кормом, пищей и лишь в незначительном количестве вырабатываются в кишечнике ее нормофлорой. При развитии дисбактериоза в пищеварительной системе, на фоне кандидамикозов, нарушаются процессы усвоения витаминов из корма, их продукция микрофлорой кишечника. Применение микробного энзима литиказы с пробиотиком и прополисом на фоне кандидамикозов пищеварительного тракта способствовало повышению и восстановлению баланса водо- и жирорастворимых витаминов в печени: тиамина в 6,2–7,46; рибофлавина в 3,31–3,54; пиридоксина в 3,93–4,33; цианокобаламина в 6,67–9,0; аскорбиновой кислоты в 3,27–4,24; ретинола в 3,23–3,84; токоферола в 6,92–7,17 раза.

Candidamycosis of the digestive tract of geese can cause a violation of the antioxidant system of the liver, the normal functioning of which is provided by vitamins. In this regard, studies have been conducted to determine the balance of vitamins in the liver, since many of them enter the body with feed, food and are produced only in small quantities in the intestine by its normoflora. With the development of dysbiosis in the digestive system, against the background of candidamicosis, the processes of assimilation of vitamins from feed, their production by the intestinal microflora are disturbed. The use of the microbial enzyme liticase with probiotic and propolis against the background of candidamicosis of the digestive tract contributed to the increase and restoration of the balance of water- and fat-soluble vitamins in the liver: thiamine in 6.2–7.46; riboflavin in 3.31–3.54; pyridoxine in 3.93–4.33; cyanocobalamin in 6.67–9.0; ascorbic acid in 3.27–4.24; retinol in 3.23–3.84; tocopherol in 6.92–7.17 times.

Authors: Маннапов А.Г. , Анахина Е.А. , Овчинникова М.А.
Published: May 2022

Мёд – как биоресурсный продукт обладает физико-химическими свойствами, которые зависят от принадлежности к ландшафтным зонам со специфическим набором пыльцевых зерен, экологических условий территорий, температурного диапазона, связанного с климатическими условиями в период цветения растений. Установлено, что влажность мёда и содержащиеся в нём инвертированные сахара обладают термостабильностью относительно климатических условий. При этом аминокислотный показатель, обладает термолабильностью к резким перепадам температур и имеет более высокие значения в тех субъектах Российской Федерации, где отклонения от среднегодовой температуры невелики. С повышением среднегодовой температуры показатель активности диастазы незначительно возрастает. Следовательно, знания зависимости качественных показателей мёда от климатических параметров позволит производить мёд с заданными свойствами и рационально использовать земли Российской Федерации. Корреляционные характеристики мёда и климатических условий с произрастающими медоносными растениями в различных субъектах России, позволит снизить себестоимость производимого мёда с заданными параметрами качества.

Honey as a bioresource product has physical and chemical properties that depend on belonging to landscape zones with a specific set of pollen grains, environmental conditions of the territories, temperature range associated with climatic conditions during the flowering period of plants. It has been established that the moisture content of honey and the inverted sugars contained in it have thermal stability relative to climatic conditions. At the same time, the amino acid indicator is thermolabile to sudden temperature changes and has higher values in those constituent entities of the Russian Federation where deviations from the average annual temperature are small. With an increase in the average annual temperature, the indicator of diastase activity slightly increases. Consequently, knowledge of the dependence of the quality indicators of honey on climatic parameters will allow the production of honey with the desired properties and the rational use of the lands of the Russian Federation. Correlation characteristics of honey and climatic conditions with growing melliferous plants in various regions of Russia will lead to a reduction in the cost of honey production with specified quality parameters.

The economics of the performing arts before and during the COVID-19 pandemic. Part 1: cost-output-profit analysis on the example of a performance
Authors: Morozova D. L.
Published: May 2022

The article demonstrates the cost-output-profit method possibilities for use by cultural organisations, studies the hypothetical cost recovery possibility from entertainment events, develops practical tools for their financial analytics. Managerial and financial analysis, econometric and graphical construction functions methods have been used. The “proof to the contrary” methods have been applied to investigate the performing arts organisations unprofitability, first substantiated by W. Baumol and W. Bowen. With regard to cultural organisations in the conditions of two-year epidemiological restrictions, a normative threshold occupancy of the hall has been established. Retaining a certain revenue share from ticket sales is not enough to cover current rental costs. In this context, economic performance analytics (operational leverage calculation, break-even analysis) is necessary to analyse the performing arts organisations losses in a pandemic. On the example of the “increased demand” performance, the hypothesis on the existence of a break-even point in which incomes and expenses are balanced has been rejected. The novelty of the study lies in fact that different methods of calculating production costs for theatres have been summarised and a methodology for checking the break-even points existence for organising entertainment events in the long and short term has been presented.

Published: May 2022

Recently, there has been an increase in the number of companies seeking to create digital platforms. Developing and investing in their own original content has opened up the opportunity for Russian services and companies to promote it on foreign platforms, gaining access to new markets and increasing attractiveness for potential foreign investors. The cultural content transmission works on the principle of streaming, which continuously delivers individualised information to the user via the Internet. Domestic OTT services, unlike TV channels, have not yet decided on their positioning. Platforms do not focus on individual segments, but on a variety of content that has a potential viewer. This strategy is aimed at attracting the maximum number of new subscribers. The emergence of streaming services has brought with it new opportunities for producers from various countries. In order to effectively promote audiovisual content, the authors justified and selected criteria for conducting a comparative analysis of mechanisms for promoting audiovisual works on foreign OTT services so that the company could choose the most appropriate one for itself.

Currently, a draft federal law reflecting the general principles of the local self-government organisation in the public power single system is being discussed. The article analyses the main provisions of this draft law related to the public self-government development, civil society and the representative power formation at the municipal level and identifies their imperfections.
Perfectionism and rational-emotive behaviour as a motivational policy for human resource management
Authors: Filyasova Yu. A.
Published: May 2022

The article considers the concept of a perfectionist motivational policy, which promotes achieving a high level of intrinsic employee motivation that ensures accomplishment of the organisational duties maximum amount; meanwhile, additional compensation produces a motivation displacement eﬀect. Theoretically, perfectionism, as the organisation corporate culture value, contributes to a signiﬁcant resources saving for the personnel maintenance and development. Employees who ﬁnd themselves in a corporate perfectionist culture have the advantage of achieving a high autonomy level due to developing integrative abilities for regulating social actions. Perfectionist motivational policy is more typical for the company`s growth cyclical stage and more beneﬁcial for young people who have high goals regarding their professional development. Rational-emotive employees behaviour is a perfectionism operational correlate oriented towards catastrophic attitudes which stimulate continuous activity, maximum involvement in the organisation activities and the achievement of not only operational but also long-term company goals. Perfectionist motivational policy requires an independent employee performance appraisal, which limits the individuals’ personal inﬂuence on the organisation’s human resources policy. Inconsistency in implementation of the motivation structural elements not only hinders the motivation internalisation, but also provokes a rise in distrust of power structures in general due to the personnel management low culture in the organisation.

Published: May 2022

The aim of the study is to develop scientiﬁc and methodological provisions for assessing the investment attractiveness of the region’s development poles and their approbation on the materials of the Sughd region of the Republic of Tajikistan. At the same time, a methodology should be developed for determining and justifying the capital investment objects with the highest return of the region’s development pole and growth point. The main objective of the research paper is to assess the investment attractiveness of the development poles as objects that most eﬀectively use the region’s limited resources. The research methods are based on the principles of system-complex, deterministic and causal approaches in combination with the principle of dynamism. In relation to the Tajik regions considered as quasi-economy, the following range of indicators has been substantiated and proposed: the region’s enterprises production total proﬁtability; market conditions (the industry production volumes dynamics and the development poles); competitive situation (the large competitors number in the region); the ratio of proﬁtable and unproﬁtable enterprises; average labour productivity; the growth locomotives presence in the region. Based on the accounting and analysis of these indicators, a comparative assessment of the investment attractiveness of the North Development Pole and the food industry of the Sughd region of the Republic of Tajikistan has been carried out. It has been proved that the investment attractiveness of the development pole is 2.3 times higher than the investment attractiveness of the food industry chosen as a base for comparison. The results of the study can be used in the regional investment policy development processes and state regulation of spatial development.

Published: May 2022

The issues of competitiveness such as why some companies reach success, while others not, how companies diﬀer and how they are managed within the chosen strategies to reach the state of competitiveness are the key for the organization of any type and industry. Some researches had a tendency to fragment or disintegrate the important parts of this problem, but the purpose of this paper is to integrate the main elements of the competitiveness phenomenon into the complex system and oﬀer a wide practical view over the cornerstones of a company’s competitiveness in a contemporary environment. In this article the author reveals her understanding of the concept of modern company’s competitiveness, then in the main part oﬀers the qualitative model – the system of company’s competitiveness which should lead to ﬁnancial competitiveness. The presented framework is practice-oriented and based on factors and eﬀorts that depend on the company itself, but goes beyond the resource-based view or a particular single strategy school, highlighting the importance of a complex approach.

Published: May 2022

Heteroatom-doped carbon nitride (CN) materials have shown much potential as metal-free photocatalysts for water splitting. Graphitic phosphorus-linked triazine network (g-PCN) materials are a unique class within this family of materials, but remain difficult to access due to long reaction times annealing at temperatures above 500 °C and often afford ill-understood structures. Here, we reveal a milder, lower temperature approach for the synthesis of catalytically active g-PCN materials through combining a room-temperature mechanochemical reaction of sodium phosphide and cyanuric chloride with brief (1 hour) annealing of the milled material at 300 °C. This rapid, low temperature procedure yields ordered g-PCN catalysts whose layered structure was determined through a combination of magic-angle spinning nuclear magnetic resonance (MAS NMR), X-ray photoelectron spectroscopy (XPS), powder X-ray diffraction (PXRD) and transmission electron microscopy (TEM). An excellent level of accuracy to simulated 31P MAS NMR signals and PXRD patterns were obtained for the structure of the synthesized layered phosphorus-linked triazine networks following dispersion-corrected density functional theory (DFT). The mechanochemically-generated g-PCN is a highly effective photocatalyst for the hydrogen evolution reaction, producing 122 µmol H2 h-1 g-1 under broad spectrum irradiation.

Published: May 2022

The green transition requires new strategies to develop active and stable nanomaterials for energy conversion. We describe the preparation of Pd-Au bimetallic nanocatalysts using a surfactant-free electrodeposition method in a deep eutectic solvent (DES) and test their electrocatalytic performance for the formic acid oxidation reaction (FAOR). We use choline chloride plus urea DES to tune the composition of Pd and Au in the bimetallic nanostructures, as well as their morphology and active surface area. We measure the increase in the electrochemically active surface area (ECSA) of the prepared Pd-Au bimetallic surfaces by Cu underpotential deposition (UPD). Our results indicate a surface area increase of 5 to 12-fold compared to Pd and PdAu extended polycrystalline electrodes. We observe that the higher activity of Pd-Au nanostructures is principally due to its increased active area. Our results also reveal that Pd-Au nanostructures with ca. 50% of Pd and Au display the best activity and stability in relation to the Pd mass loading proving the synergy between Pd and Au in the bimetallic catalyst. We highlight that an in-depth analysis of the ECSA, as well as surface and electronic structure effects in bimetallic nanostructures, are crucial aspects for the rationalization of their catalytic properties.
Protein-Induced Delubrication: How plant-based and dairy proteins affect mouthfeel
Authors: Vladescu Sorin-Cristian , Gonzalez Agurto Maria , Myant Connor , Boehm Michael , Baier Stefan , Yakubov Gleb , Carpenter Guy , Reddyhoff Tom
Published: May 2022

Understanding how certain proteins cause astringency is necessary in order to improve the mouthfeel and popularity of plant-based foods. To this end, we studied protein interactions during oral processes using a PDMS-PDMS interface lubricated by ex-vivo human saliva. Friction measurements and in-contact imaging were implemented, while food consumption was simulated by introducing model plant and animal-based proteins. All but one of the protein samples caused an increase in measured friction and this correlated with astringency ratings from a human taste panel. This is attributed to delubrication as the salivary pellicle is removed, since food proteins interact with salivary proteins thus disrupting their adhesion. This interaction is shown to occur both on the surface and in the bulk of the fluid. However, the debonding of the pellicle requires frictional shear stress (i.e., rubbing). Food proteins in isolation are themselves shown to be surface-active and form boundary films, which can adhere following removal of the pellicle. The mechanical action of protein particles in the delubrication process was isolated by filtering and shown to account for a moderate (<33%) increase in friction magnitude accompanied by a significant (>90%) increase in frictional noise. The flow and deformation of these particles was also visualised thus demonstrating how the microscale breakdown of food can be studied.

Vibrational spectroscopy coupled with isotopic labeling provides many insights into dynamic processes within various molecular systems. Here, a newfound utility of surface-enhanced Raman scattering (SERS) spectroscopy as a tool to study noble metal-anchored thiol monolayers is demonstrated for a pair of L-cysteine isotopologues competing to bind the surface of silver nanoparticles (AgNPs). According to our DFT calculations, SERS spectra of L-Cys could be sensitive to 12C/13C and 14N/15N isotopic substitutions, which has been experimentally confirmed for the pair of L-Cys isotopologues: Cys-cabn (all 12C/14N) and Cys-CABN (all 13C/15N). In the AgNP-anchored state, the two isotopologues reveal distinct Raman shift values (1577 cm-1 / 1633 cm-1) of the band assigned to C=O stretching. This characteristic SERS feature has been subsequently employed to probe various exchange scenarios between AgNP-bound and free L-Cys molecules. As the exchange involves two spectrally distinct but chemically identical molecules, the process is exclusively entropy-driven ultimately leading to the equilibrium state in which Cys-cabn/Cys-CABN concentration ratios in the Ag surface-bound layers and the bulk solution are identical. In a system containing AgNP-L-Cys and an excess of free L-Cys molecules, the exchange energy barrier limits the overall kinetics. Although the SERS-monitored rate of progression toward the equilibrium state under ambient conditions (25 °C) is negligible, a very steep acceleration of the exchange is observed at 50 °C. While the temperature-induced transition is very abrupt, it is still reversible with cooling. We argue that the dramatic acceleration of the dynamics of the L-Cys exchange between free and AgNP-bound molecules may be rationalized as a collective phase transition to an excited and reaction-prone state. Our work highlights unexplored potential of SERS spectroscopy coupled to isotopic exchange as a tool to study obscured dynamic phenomena within metal-anchored adsorbate layers.

Nanocrystalline cellulose has gained much attention from the researcher. It provides many
applications such as polymer additive, packaging, and tablet filler. This review established
the recent isolation method of nanocrystalline cellulose from agricultural by-products,
aiming to reduce waste that will affect the environment. The current nanocrystalline
cellulose application as a food additive in many food products and its toxicological
analyses was discussed. This work can be used as a guideline by researchers and food
manufacturers to isolate nanocrystalline cellulose from agricultural waste and its use as a
fat replacer in food products.

Grain protectants such as inert dust help prevent quality deterioration during post-harvest
storage. Understanding the physical characteristics of inert dust and inert dust treated
wheat kernels could help develop solutions to flow problems of stored grain. This research
investigated the effects of the moisture content of a synthetic amorphous zeolite and the
rates of application on some physical properties of the amorphous zeolite and wheat
kernels. Three levels of moisture (2.0%, 6.0%, and 10.0%) of the zeolite were applied at
three rates (0.5 g/kg, 1.0 g/kg, and 2.0 g/kg) on 100 g wheat samples (10% m.c, wet basis)
in triplicates. Image analysis, laser diffraction, Thermogravimetric analysis (TGA),
Scanning Electron Microscopy (SEM), gas pycnometry, and the Single-Kernel
Characterization System (SKCS) were used to characterize the physical properties. The
particle size of the amorphous dust increased with increasing moisture content.
Conversely, shape parameters (circularity, aspect ratio, convexity, and solidity) generally
decreased with increasing dust moisture contents. When wheat was mixed with the
amorphous dust at increasing rates and moisture levels, the bulk density of wheat
decreased, while the tapped density and the angle of repose increased, resulting in higher
Hausner ratios and Carr Index values. Treating wheat with the amorphous dust at the
highest moisture (35%) and application rate (2.0 g/kg) caused the treated wheat to
transition from an acceptable flowability to a poor flowability along with a decrease in
wheat kernel hardness. Our data suggest, however, that a range of moisture content (2-6%)
and an application rate (0.5 g/kg) mitigate the adverse effects on wheat flowability. This
study also highlights the importance of drying any amorphous dust or allowing dust to
equilibrate to the experiment temperature before conducting tests on physical properties.

1980’lerden sonra ekonomik ve sosyo politik üretim sistemindeki değişiklikler çalışanlar, işverenler, ülkeler, istihdam ve emek piyasaları açısından birtakım değişikliklere yol açmıştır. Özellikle Fordizmin çöküşünün ardından neo-liberal iktisat politikalarının uygulamaya konulması dünya emek piyasalarını derinden etkilemiştir. Fordist üretim sisteminde yer alan standart veya tam zamanlı istihdam yerini esnek çalışma ilişkilerine bırakırken gelişen ve gelişmiş ülkelerde emek piyasaları dönüşüm geçirmiş, standart dışı istihdam adeta norm haline gelmiştir. Nitekim 1980’lerden sonra ekonomik, sosyal politik ve üretim sistemindeki değişiklikler çalışanlar, işverenler, ülkeler, istihdam açısından birtakım değişikliklere yol açmıştır. Bütün bu gelişmelerle birlikte 21. yüzyılın ilk başlarında ulusal emek piyasaları işlevlerini yitirmeye başlamış, işverenler ürün piyasalarında artan rekabet ve üretim yöntemlerinde teknolojik değişiklik ile karşı karşıya kalmışlardır. “Dijital Çağ” olarak adlandırılan bu dönem, yeni iş yapılarını ve çalışma ilişkilerini ortaya çıkarmaktadır. Alternatif çalışma şekilleri tercih edilmeye başlanmıştır. Ne var ki bu alternatif çalışma şekilleri birbirinin yerine kullanılmaya başlanmış, kavram kargaşasını da beraberinde getirmiştir. Bu çalışmanın amacı birbirlerinin yerine kullanılan çalışma şekillerinin literatür taraması ile kavramsal olarak analizini yapmaktır. Birbirlerinin yerine kullanılan bu çalışma şekillerinin farklılaşan ve benzer noktalarının olduğu görülmektedir.
