Electrochemical Sensing/Biosensing ‐ Bench to Market

The proposition of new sensors based on carbon (nano)structures as well as metal (nano)particles is a great alternative for electroanalysis. In this context, graphite, carbon nanotubes, graphene, carbon black and fullerene, as well as gold, silver, platinum, copper are the most common materials employed [1]. Also, biomolecules such as antibodies, DNA sequences, enzymes and aptamers can be promising molecular recognition elements and enable specific sensor/biosensor designs, with interferent species [2]. Since the pioneering works from Professor Joseph Wang [3,4], the screen‐printed and disposable electrodes have been reported in the literature as options to be used in point‐of‐care and point‐of use sites. Also, the evolution of 3D printing [5] and wearable devices have led to an increase in the number of papers reporting on their use.. The “Achilles heel” is that the laboratory creations don't make it to the market place [6]. Therefore, academia needs to think more about in the validation, demonstration and promotion of the laboratory developed technology with of new companies based on startups, for example, to attract investments and promote these sensors to commercial ones. In this context, the special issue “Electrochemical Sensing/Biosensing ‐ Bench to Market” brings the discussion and advances of electrochemical sensors, which can be used in many areas, such as medical, environmental, food safety, pharmaceutical, and forensic. For this purpose, the preparation, characterization, and application of these devices have attracted interest. Studies of the production, shelf‐life as well as reproducibility, and repeatability have been highlighted for mass production. Important subjects such as screen printing, and 3D printing are welcome for submissions. Therefore, we expect you to enjoy this Special Issue published in Electroanalysis.

The role of λαϊκή αγορά (“street market”) in modern greek towns

The article discusses the phenomenon of “people’s market” in contemporary Greek cities and towns. Historically, the market in Greece has played an important role not only as a place of trade, but also as a concentration of social and political life. The word αγορά, derived from the ancient Greek verb ἀγορεύω (“to speak publicly”), meant not only a market square but also people’s assembly in Ancient Greece. In modern society, the “people’s market” has almost lost its political function. From a commercial point of view, it should have been replaced by mega-stores, supermarkets, and online commerce, especially during the covid pandemic. However, today in Greece this phenomenon does not lose its relevance and even acquires new functions. In a large city, the “people’s market” is embedded in a new ideology of environmental friendliness of the goods for sale and in the discourse related to the identity of the Modern Greek. In addition, a street market in a city retains the archaic functions of socializing residents, exchanging information, and being a barometer of political sentiment. For rural residents, λαϊκή αγορά is an opportunity to sell an agricultural product and exchange information and contact with the urban environment. Internationally, outside Greece, the Greek folk market is sometimes positioned as a distinct brand.

The Complexities of Regulating Traders’ Activity: The Case of Small Traders in Ouagadougou's Rood Woko Market (Burkina Faso)

This paper analyses the complexity of regulating the activities of small traders at the Grand Marché in Ouagadougou, Burkina Faso. Markets in Africa are places where small-scale trading takes place par excellence, and the traders who work there are generally considered to be self-employed. The plurality of regulations governing commercial activity observed there seems to be particularly conducive to such an analysis. We examine these complexities within the theoretical framework of “social regulation” as well as that of “normative pluralism,” which encompasses both official and practical norms. We show that the work of traders is regulated both by norms issued by the Régie Autonome de Gestion des Équipements Marchands (Independent Management Board for Commercial Facilities) – an official structure – and by traders’ own practical norms, which have both collective and individual aspects to them. The complexities of the relationship between these official and practical norms lie in the fact that sometimes they are not always articulated and may both co-exist and contradict each other.

Sentiments Unleashed : Pioneering the Frontier of Sentiment Analysis through Cutting-Edge Applications and Methodologies

Sentiment analysis is a powerful tool within Natural Language Processing (NLP), assists businesses and researchers in discerning the emotions, attitudes, and beliefs conveyed in written language. The increasing availability of textual data, including social media posts, product reviews, and customer feedback, has driven a significant increase in the demand for sentiment analysis. The primary goal is to uncover underlying emotions expressed through diverse word combinations, sentences, or paragraphs. By scrutinizing language nuances, it identifies a wide range of emotions, from joy and sadness to criticism and admiration. This profound understanding, facilitated by sentiment analysis, provides valuable insights into public perception, market trends, and consumer behaviours, empowering businesses to refine strategies, improve products, and enhance customer experiences. As sentiment analysis tools and techniques continue to advance, they present opportunities for progress, assisting businesses in navigating shifts in public opinion and enabling researchers to delve into the intricacies of human expression through text. With the continuous surge in textual data, sentiment analysis retains its significance in guiding stakeholders from diverse industries toward informed decisions and a comprehensive understanding of human sentiment. This research explores advanced approaches in sentiment analysis, including machine learning, lexicon-based methods, hybrid and ontology-based models, and multi-modal techniques, examining various levels, classifications, and methodologies.

THE MEDIATING ROLE OF EARNINGS MANAGEMENT IN THE RELATIONSHIP BETWEEN THE FIRM LIFE CYCLE AND THE COST OF EQUITY: EVIDENCE FROM BANKS IN IRAQ

The present study seeks to examine the interaction among three separate variables. The initial variable relates to the organization's life cycle and financial attributes. The second variable pertains to the procedures of firm management that influence performance and financial condition, as demonstrated by earnings management. Investors manage the impact of the previous two factors by weighing the risks and potential gains, which the corporation terms as "the cost of equity." We utilized these variables to analyze 15 Iraqi commercial banks that have been listed on the Iraq Stock Exchange for 10 years, equivalent to 150 observations.Our quantitative assessment of the study variables, conducted using models from the relevant literature, has yielded significant findings. We have uncovered a direct correlation between the life cycle and earnings management, indicating a beneficial association. Moreover, we have revealed that each factor exerts a unique and favourable influence on the cost of equity. The correlation between the life cycle and earnings management has led to an increase in the favourable influence of earnings management on the cost of equity. Conversely, the life cycle now has an inverse impact on the cost of equity, with the cost of equity being mainly influenced by the maturity stage. These findings have important implications for stock market traders, as they guide them to direct their investments towards banks that offer higher returns relative to the level of risk, considering the age group and the administration's approach to managing announced profits. This study's implications for stock market traders are significant, as it provides them with valuable insights for making informed investment decisions. It also serves as a guide for future studies in this field.

Can you bear with me? A comparison study of multifaceted discrepancy–brand avoidance relationships between China and the USA

PurposeBrand information is ubiquitous online and offline; consumers exhibit brand avoidance tendencies towards brand stimuli when there is a discrepancy between a brand image/personality and one’s self-concept. Given the multifaceted culturally constituted self-domains and self-importance, this research investigates how cultural variation affects reactions to self-brand discrepancy, considering two types of narcissist orientations.Design/methodology/approachUsing national culture as proxy for cultural orientation, sample data were collected through surveys administered to 410 participants (210 in China and 200 in the USA). A multi-group structural equation model was adopted to examine the conceptual model and proposed hypotheses. The follow-up qualitative study was conducted to allow further discussion of the quantitative results.FindingsThe results show that self-brand discrepancy can only be converted into brand avoidance tendency through the activation of cognitive dissonance for both Americans and Chinese. Specifically, for Chinese consumers only (ideal) social identity self-brand discrepancies can activate avoidance behaviour. In addition, grandiose and vulnerable narcissism orientations co-exist for both Chinese and Americans, these negatively moderate the relationship between social self-brand discrepancies and cognitive dissonance. For US consumers, idealised identity discrepancies mitigate dissonance; only those with a vulnerable narcissistic orientation would act on avoidance when experiencing dissonance.Originality/valueBy incorporating cultural variations in the investigations of self-brand discrepancy, this paper advances existing knowledge on dissonance and coping mechanisms. In addition, by bringing narcissistic orientations to the fore, it allows for a deeper understanding of how these cultural variations operate. In addition, our research provides important guidelines for brand practitioners to better leverage their marketing campaigns in offline and online contexts and to reduce brand avoidance tendencies across the international marketplace.

Effects of Packaging on Consumer Buying Decision: A Study of African Black Soap (Alata Samina)

Product packaging plays a key role in consumer purchasing decision as packaging promote brand identity and customer loyalty. However, the African black soap prepared in Ghana has not seen the best of packaging, hence, its rejection in international marketplace. It is in this vein that the researcher sought to examine effect of packaging on consumer buying decision of African black soap (Alata Samina). Correlation and cross-sectional design were used. Cluster and simple random were used to select 245 respondents. Findings revealed that best packaging influence consumers’ perception to buy local Alata Samina soap recorded a cumulative mean of 4.69198 and standard deviation of 3.31842, suggesting respondents’ agreement that best packaging induce consumer buying decision. In terms of relationship, it was clear that strong positive link exist between packaging elements and consumer buying decision; Packaging colour had r(245) = 0.882, p<0.05, Background image had r(245) = 0.881, p<0.05, Packaging materials had r(245) = 0.882, p<0.05, Font style had r(245) = 0.876, p<0.05. Printed information had r(245) = 0.772, p<0.05, Labelling, wrapper design and creativity had r(245) = 0.882, p<0.05. Standard Multiple Regression was used to analyzed the effect of packaging elements on consumer buying decision and the result were packaging colour had 53.8% and statistically significant effect of r(245) = 0.538, p<0.05. Brand image had 85.3 % and statistically significant effect of r(245) = 0.853, p<0.05. Printed information had 73.8% and statistically significant effect of r(245) = 0.738, p<0.05. Packaging materials had 62.6% and statistically significant effect of r(245) = 0.626, p<0.05. Innovation had 92.3 % and statistically significant effect of r(245) = 0.923, p<0.05. Labelling quality had 76.5% and statistically significant effect of r(245) = 0.765, p<0.05. Design of wrapper had 44.2% and statistically significant effect of r(245) = 0.442, p<0.05. However, font style had only 1.2% and this effect is not statistically significant; r(245) = 0.012, p<0.05. This means that most consumers do not believe that font style influences consumers’ purchase decision. The study recommends that Institute of Packaging Ghana, Federation of Ghanaian Exporters, Ministry of Trade and Industry, Ghana Exports Promotions Authority and Association of Ghana Industries should collaborate to improve the packaging skills of the local African black soap producer. The essence is to enable them to package their products to meet the export market standards.

Do Financial Community’s Tweet Sentiments Affect the Stock Market? Evidence from an Emerging Economy

In the era of social media and internet, Twitter (presently ‘X’) has been recognized as the prominent factor for financial markets by multiple corporates and experts. The motivation of present research hinges on burgeoning popularity of Twitter in the financial community for sharing information and impact of their hidden sentiments on financial markets. Research on tweet-based sentiments and their influence on financial markets in India is still in the infancy stage. To cover this gap, the present study empirically investigates the predictive impact of financial tweet sentiments on the Indian stock Index’s returns over a short period. The paper scraped 22,816 tweets and Nifty 50 index’s intraday hour end values for January 2023. Using Natural Processing Technique, the overall sentiments of the financial community are found as highly positive for each trading hour. Next, it presents a low positive correlation between positive sentiments, sentiment polarity, and hourly returns. Lagged negative sentiments reflect the better ability to impact current period returns than positive sentiments and polarity. Additionally, sentiment polarity and returns reflect bi-directional causation for the future period impact. Investors, stock market traders, and other practitioners can employ the proven concept of linkage between tweet sentiments and returns for constructing effective investment and trading strategies.

Split Payment as a Method of Consumer Payment in Online Buying and Selling Practices Is Reviewed From the Principle of Legal Certainty

Current technological advances have led to the development of payment methods in online buying and selling practices. Usually the payment method is made via cash and non-cash; one of the current payment methods is known as the split payment method. Split payment is a payment made using more than one payment method to complete the entire transaction. There is a case where a consumer buys goods online by paying using split payment and the consumer will be given cash back when using split payment. However, the goods that have been purchased do not reach the consumer. The consumer and the shop agreed to ask for compensation from the market place, which is a meeting place for online buyers and sellers. Based on this case, the author is interested in researching the problem of how to complete online buying and selling transactions using split payments. This research uses normative legal research methods with a statutory approach. The results of this research show that it is important to have special regulations regarding the definition and validity of split payment methods for online buying and selling transactions in order to provide guarantees, justice and consumer security in order to realize the principle of legal certainty.

Сенсорный маркетинг в условиях диджитал-экономики

In the context of the increasing complexity of marketing relations associated with the transformation of understanding the role of the consumer, the issues of a deeper study of consumer behavior and its features in the “black box” model are of particular importance, since understanding consumer motives and reactions to marketing incentives will contribute not only to sustainable production and sale of goods, increasing the effectiveness of marketing solutions and maximizing profits in the long run, but also to the fast search and selection of goods by consumers that really meet their needs. The development of sensory marketing, taking into account the emergence of new neuromarketing technologies, meets the challenges of modern society. Previous studies of the influence of sensory stimuli on consumer behavior, as a rule, focused on the use of traditional marketing tools (observation, survey, focus groups, etc.), as a result of which only one-sided results of visible consumer reactions were obtained, which do not always reflect their true intentions to purchase a product. Marketing concepts in the context of changing market relations during the transition to a post-industrial society are examined; identifies the place of sensory marketing in the digital economy and its importance in the transformation of society into a humane community, shows the relationship between sensory marketing and neuromarketing, the use of technological tools which will allow to obtain hidden neurophysiological reactions of consumers to marketing incentives, which will provide a comprehensive an approach to evaluating incentive triggers in the purchase decision-making process. The role of neuroethics in conducting these studies is indicat.

Brexit and the London housing market: An empirical contribution

This study aims to analyse the impact of Brexit on London’s housing market, exploring socio-economic and regional disparities. By examining property transaction data from 2012 to 2022, the research seeks to understand how Brexit has influenced real housing prices across different boroughs of London. The methodology involves aggregating transaction data from the Her Majesty (HM) Price Paid database and normalizing prices using the Consumer Price Index (CPI) to obtain real price variations. These data were segmented into three distinct periods: pre-Brexit (2012–2016), post-plebiscite Brexit (2016–2019), and post-implementation Brexit (2020–2022). Spatial analysis was conducted using the software Quantum Geographic Information System (QGIS), transforming point data (postcodes) into polygonal data (wards) for better visualization and comparison. The findings reveal significant socio-economic impacts, with traditionally affluent areas such as Westminster, Kensington, and Chelsea experiencing notable declines in real housing prices. Conversely, certain outer boroughs like Newham and Barnet showed resilience, with positive real price variations despite decreased sales. This geographical disparity underscores the uneven distribution of Brexit’s economic consequences, highlighting the critical role of localized economic policies and development projects in mitigating adverse effects. The results confirm existing literature on the polarization and regional inequalities exacerbated by Brexit while providing new insights into the complex interplay of local and global factors affecting housing markets. The findings emphasize the need for targeted policy interventions to address the diverse challenges posed by Brexit, ensuring both affluent and disadvantaged areas receive adequate support. This research is crucial for informing public policy, urban planning, and housing market strategies in a post-Brexit context, promoting equitable and sustainable development across London.

Deciphering the Cape Gooseberry Fruits Mycobiome for Further Safety Improvement Postharvest.

Cape gooseberries are exquisitely flavored fruits; their rapid deterioration reduces their shelf life. Understanding the unique mycobiome of fruit peels is an essential step in identifying the taxa causing postharvest loss. The current study proposes to analyze the fungal communities of cape gooseberry peels collected from an organic orchard at unripe and ripe stages and purchased from open-air market sites, using the ITS2 region metabarcoding. According to the Kruskal-Wallis test, there were no statistically significant differences found in either the phylogenetic or non-phylogenetic alpha diversity indices. Significant differences in fungal communities were observed between the market and orchard groups based on beta diversity results. Ascomycota (85.72-96.76%), Basidiomycota (3.21-13.91%), and Chytridiomycota (0.07-9.35%) were the most common fungal phyla, their abundance varying with the ripening stage and origin. Dothideomycetes in the orchard group and Saccharomycetes in the market group were the two most prevalent classes. Furthermore, we investigate which taxa showed a significant difference in abundance between the two conditions (market vs. orchard) using the analysis of compositions of microbiomes with bias correction (ANCOM-BC) test. Regardless of the phase, the orchard samples exhibited a notable increase in the mean absolute abundance of various beneficial fungal taxa, including Tilletiopsis washingtonensis and Articulospora proliferata, whereas the market samples demonstrated a high abundance of harmful yeasts and molds such as Meyerozyma guilliermondii, Candida railenensis, and Botrytis caroliniana. Although it is unclear how these microorganisms augment at the market sites and might impact the fruit quality after harvest, from a fruit safety perspective, it is essential to comprehend the diversity and variation of the mycobiome composition at different ripening stages to further develop strategies to improve food safety postharvest.

Risk-Adjusted Returns of Private Equity Funds: A New Approach

Abstract This paper introduces a new metric, α, to benchmark the performance of individual private equity funds. Our metric is substantially less sensitive to noise in fund cash flows compared to the popular public market equivalent (PME) and its generalization (GPME), while having the same aggregate pricing implications as GPME. For a large data set of fund cash flows, α estimates have much lower standard deviation across funds than does (G)PME. For buyout funds, PME and α are close, but deviate in certain subsamples. Using α increases power in regressions involving fund performance and improves performance predictability of future funds. (JEL C58, G12, G23, G24)
