Methodological Approaches for Monitoring Five Major Food Safety Hazards Affecting Food Production in the Galicia–Northern Portugal Euroregion

The agri-food industry has historically determined the socioeconomic characteristics of Galicia and Northern Portugal, and it was recently identified as an area for collaboration in the Euroregion. In particular, there is a need for action to help to ensure the provision of safe and healthy foods by taking advantage of key enabling technologies. The goals of the FOODSENS project are aligned with this major objective, specifically with the development of biosensors able to monitor hazards relevant to the safety of food produced in the Euroregion. The present review addresses the state of the art of analytical methodologies and techniques—whether commercially available or in various stages of development—for monitoring food hazards, such as harmful algal blooms, mycotoxins, Listeria monocytogenes, allergens, and polycyclic aromatic hydrocarbons. We discuss the pros and cons of these methodologies and techniques and address lines of research for point-of-care detection. Accordingly, the development of miniaturized automated monitoring strategies is considered a priority in terms of health and economic interest, with a significant impact in several areas, such as food safety, water quality, pollution control, and public health. Finally, we present potential market opportunities that could result from the availability of rapid and reliable commercial methodologies.

Expert Demand for Consumer Sleep Technology Features and Wearable Devices

Global demand for sleep-tracking wearables, or consumer sleep technologies (CSTs), is steadily increasing. CST marketing campaigns often feature a scientific component, but the scientific relevancy and monetary value of CST features within the sleep research community remains unquantified. Sleep medicine experts were recruited through social media and nonprobability sampling techniques to complete a survey identifying sleep metrics and device features that are most desirable to the scientific community. A hypothetical purchase task (HPT) estimated economic valuation for devices with different features by price. Forty-six (N=46) respondents with an average of 10±6 years’ experience conducting research in real-world settings completed the online survey. Total sleep time was ranked as the most important measure of sleep followed by objective sleep quality while sleep architecture/depth and diagnostic information were ranked as least important. Experts preferred wrist-worn devices that could reliably determine sleep episodes as short as 20 minutes. Economic value was greater for hypothetical devices with longer battery life. These data set a precedent to determine how scientific relevance of a product impacts the potential market value of a CST device. This is the first known attempt to establish consensus opinion or economic valuation for scientifically-desirable CST features and metrics using expert elicitation.

Potential market and impact of clean hydrogen development to 2050 in Vietnam

Hydrogen plays an important role in the energy transition towards a zero-carbon economy. Blue hydrogen and green hydrogen are potential sources to replace fossil materials and fuels in the fields of refining - petrochemical, production of fertiliser, steel, cement, electricity, and transportation. The potential demand for clean hydrogen in these areas has been evaluated along with the impacts and benefits of hydrogen development. Accordingly, the potential hydrogen market can reach an output of 22 million tons/year by 2050. The development of hydrogen in the fields will create new markets with a total value of USD 100 billion in 2035 and USD 1,200 billion in 2050. In terms of the environment, replacing fossil materials and fuels with hydrogen reduces the total national CO2 emissions by 5.4%. In order to develop and complete the hydrogen value chain in Vietnam, it is necessary to set goals and roadmaps along with appropriate policies. Recognising the importance of hydrogen to the operation of the oil and gas and energy sectors in general, the Vietnam Oil and Gas Group (PVN) has developed a scientific research programme on the development of production, storage, transportation, distribution, and efficient use of hydrogen in Vietnam in the 2021 - 2025 period.

The Coordination of Multi-Stage Discounts in a Dual Channel Fresh Agricultural Pro-duce Supply Chain: Minimizing the Loss of Quantity and Quality

This paper explores the coordination of the agricultural cooperative to supermarket or E-commerce sup-ply chain, under the condition of quantity loss with a mixed decay function of exponential and logistical distribution. The nature of this process is analyzed, and the corresponding demand and supply functions with single- and multi-stage discount strategies are constructed respectively to create a working model. The optimal discount ratios for supermarkets and agricultural cooperatives in decentralized and central-ized decision-making modes coupled with single- and multi-stage discounts are calculated respectively. Finally, a universal optimal strategy is designed, which can be applied to various quantity decay scenarios and makes the discount strategy more generalized. The results show that discounts can coordinate supply chains more effectively; not only is fresh agricultural produce sold before it starts to rot, but the benefit conflicts arising from both supermarkets vs. cooperatives and traditional vs. E-commerce channels are equilibrated. Further, multi-stage discounts are more effective than single-stage ones, but optimal discount ratios rely on the initial quantity of fresh agricultural produce in the supply chain; its market share in the traditional distribution channel; the potential market size; retail price; the price sensitivity coefficient of the channel; the cross-elasticity coefficient of prices between different channels; and the properties of the quantity loss.

Do Profit-Sharing Rate, Promotion Media, Location, And Service Facilities Affect Muslim Decisions To Use Islamic Banks?

The majority of Indonesian people are Muslim, making Indonesia a potential market in the development of Islamic banking. The purpose of this study was to determine whether profit-sharing rate, promotion media, location, service facilities affect the decisions of the Muslim community to use Islamic banks. This type of research is quantitative research, which uses the method of structural equity modelling (SEM). The large sample size for the SEM method is based on the number of indicators in the variable due to the enormous population size, namely Muslims in Indonesia. The number of respondents in this study was 214 people. The results of this study indicate that profit-sharing rate, promotion media, location, service facilities do not affect the decisions of the Muslim community to use Islamic banks. Muslims are more likely to choose Islamic banks because of the halal label than other factors. Factors that generally make customers use conventional banks do not apply to Islamic banks. This research can be a reference or a reference for Islamic banks in making policies. Variables that are proven to have no effect can be eliminated in making policies to increase Islamic bank customers.

Innovative Entrepreneurship for Online Business: Qualitative Study

Entrepreneurship in online business is related to the rapidly growing number of internet literacy in Indonesia. Currently, 160 million people access the internet, making Indonesia an economical cake that creates a potential market. It encourages market competition and innovation in the red zone. Competition triggers business actors, including entrepreneurs, to rethink the strategies applied to win market competition relevant to the current phenomenon. The research question is related to how online business entrepreneurs take advantage of innovation to survive the business turbulence, such as developing technology, changing regulations, market tastes, and the need for social distancing in a pandemic situation. Innovative Entrepreneurship (IE), initially inspired by Schumpeter and Lumpkin Dess, is now further transformed by the evolution of generations from generation X to generation Y (millennial generation). Millennials have different characters and lifestyles, so that in terms of entrepreneurial characteristics, millennials have an IE perspective that brings their uniqueness. In line with the development of the internet and application breakthroughs by unicorn developers, E-marketplaces have become an interesting online business phenomenon to explore and create the dynamics of IE. This study is based on the perspective of technology-based entrepreneurship through a qualitative approach. The results of the study obtained an IE construct with millennial ownership. The construct of IE in the online business environment is formed by four dimensions, namely technology, work atmosphere, organizational strategy, and market agility. By applying these four dimensions, the IE construct will foster entrepreneurship to formulate better ways to survive and win the competition in the e-marketplace business environment.

Broadband Market Sizing in Brazil

The objective of this study is to predict the potential broadband market in Brazil. This is done by combining information from two national databases: the 2010 census and the 2015 PNAD (National Household Survey). The 2015 PNAD is used to estimate the probability of the household accessing internet by broadband technology, using a logit regression. The broadband market is predicted using the estimated model with the same covariates found in the 2010 census. The prediction indicated a potential market of 45 million households, an additional of 6 million households in relation to the current situation. The new size of the broadband market is estimated if there is a 10% increase in the average penetration of broadband services in the main metropolitan areas. In this scenario, the new market covers 50.7 million households.

A Model of Product Line Marketing

Firms offer a variety of products to meet different customer needs. In many horizontally differentiated markets, prices are stable, and firms make infrequent adjustments to their product lines. Although prior research focused on product line design, we investigate how firms should allocate their marketing effort when their product lines are fixed. We propose a simple model to analyze product line marketing. Our model exhibits a flagship product effect in which the firm’s optimal marketing effort is concentrated, provided that the ratio between consumer tastes dispersion and the convexity of the cost of marketing effort is below a threshold. The flagship product is selected according to a marketing effort allocation index that measures the trade-off between a product’s markup and its potential market share. This result is robust with or without competition and whether prices are exogenous or endogenous. Firms often experience shocks to their marketing cost because of technological improvement or externalities. If a monopolist’s cost of marketing effort declines, she should place more emphasis on a low-utility, high-markup product. Conversely, if the cost increases, the monopolist may find it beneficial to focus her marketing effort on a high-utility, low-markup product. When multiproduct firms compete against each other, we show that if the opponent’s cost of marketing effort decreases, there can be a spillover effect, in which the firm benefits from the opponent’s cost reduction, thereby leading to a win-win situation.
