Performance evaluation of multivariate deep-time convolution neural architectures for short-term electricity forecasting: Findings and failures

Deep learning (DL) models hold great promise in enhancing the decision-making abilities of electricity market participants and system operators in the short term, as they excel at capturing the intricate interdependencies and uncertainties in electricity consumption. Nevertheless, currently, the adoption of DL models for electricity prediction is not keeping up with the advancements in DL research. Within this framework, the aims of this study are to examine the probabilistic, multivariate, and multihorizon time series prediction of deep time convolution neural (DTCN) models. The effectiveness of DTCN in forecasting electricity consumption over daily, weekly and monthly time horizons is emperically assessed. We analyze both probabilistic and deterministic predictions. The evaluation data comprises real residential electricity consumption, average temperature and humidity with hourly granularity, collected over one year from a residential building. For evaluation, we considered accuracy and uncertainties, sensitivity to hyperparameters, the impact of exogeneous variables, as well as computational efficiency. Results show that the probabilistic models offer greater advantages when it comes to forecasting on multihorizons, especially for diverse datasets with non-uniform time series models. Unlike traditional models, the DTCN models demonstrated superior performance in capturing complex patterns and reducing forecast errors in short-term scenarios. However, their performance can be influenced by the sensitivity of hyperparameters. These findings can act as a benchmark for quantitatively assessing the performance of novel multivariate DL models in predicting electricity demand.

Considering that the egg products of purebred chickens of farmers in waterfront villages have not been able to meet the standard needs of around 20% of the local market needs, so that purebred chicken eggs are imported from outside the region to meet egg needs. The lack of supply from within this area is not able to meet local needs, making the opportunities for the waterfront village community to develop laying hen farm management very wide open. This research is to find out the Perspective of Islamic Business Ethics on the implementation of Chicken Farm Management. The research method used is qualitative research with sample determination. The key informant in this study is a chicken farmer in Pinggir Air. Non-key informants are people who are considered to know the problem being researched. The result of this study is an indicator of the management of chicken farms in Pinggir Air Village, this chicken farming business uses land and personal capital partly from loans from conventional banks. This chicken farming marketing system uses a direct marketing system. The perspective of Islamic business ethics on the implementation of chicken farm management in Pinggir Air Village has fully applied the principles of Islamic business ethics based on unity (monotheism or unity) by not leaving the essence of worship to God, as well as establishing a balance in determining fair egg prices for all consumers and being responsible and honest in determining and maintaining egg quality.

Determinants of Consumer Preferences for Imported and Domestic Wooden Furniture: Lessons from Addis Ababa, Ethiopia

Abstract Currently, domestic wood product enterprises in Ethiopia are facing increasing competition from imports. Therefore, more needs to be done to address the evolving dynamics in public preference and taste while overcoming the pressure from the import market. However, the wooden furniture sector in Ethiopia is scarcely researched and documented to support the production and marketing system. This study investigated the determinants of consumer preferences for imported and domestic wooden furniture in Addis Ababa, Ethiopia. Multistage sampling was used to select a sample size of 385 consumers who had purchased wooden furniture. Data were collected using a structured questionnaire and analyzed through descriptive statistics, Kendall’s test, and the multivariate probit (MVP) model. The findings revealed that imported wooden furniture scored higher in terms of finishing, color, compatibility with other objects, and design, whereas domestic wooden furniture excelled in terms of durability, environmental friendliness, maintainability, and affordability. The MVP results indicated that wooden furniture preference was influenced by factors such as age, number of years in marriage, family size, number of years living in the city, occupation, and exposure to advertisements. The study recommends that domestic furniture companies enhance the finishing, design, color, and other desirable attributes of their products to attract and satisfy domestic demand, potentially reducing the need for imports. By focusing on improving multiple attributes, companies better cater to the preferences of consumers. Additionally, furniture companies should consider the diverse socioeconomic characteristics of consumers during the production of their furniture products to meet a range of needs.

A dispatch model coordinated power and heating system in electricity market considering resource aggregation and decomposition

Abstract With the high proportion of installed capacity of renewable energy, the stability and robustness of the new power system need to be improved. The integration of the power system and heating system is an orientation to promote the ability of wind power accommodation. This thesis first introduces the integrated model considering power and heating systems. However, the integrated model requires the topology in the heat network and the parameters of heat devices, which is difficult to access and complicated to solve. Under this situation, the heat devices are aggregated into an equivalent generation unit in the power network. A coordinated dispatched model based on resource aggregation and decomposition is then proposed. In simulation, the economy, flexibility, and security of a given formulation are investigated through marginal price and units’ behavior.

Cross-border ripples: investigating stock market responses to Israel-Hamas conflict in trading partner nations using event study method

PurposeThe study will add to the current discourse on the Israel-Hamas conflict by examining the impact of the war on the stock markets of trading partners. Stock market returns inevitably rise as globalization keeps integrating financial markets and economies around the world. Thus, the impact of war is assessed across a range of indicators that are similar in some way, such as geographic location, political climate or economic standing. Thus, the goal of this study is to investigate how the Israel-Hamas war affects trading partner countries' stock performance.Design/methodology/approachEvent study methodology is applied using Morgan Stanley Capital Index (MSCI) as a benchmark index. The influence of the Israel-Hamas war on the world's major stock markets is evaluated using a market model. The study takes into account Israel and its 23 trading partners. To capture the locational asymmetry in the outcome, the countries are further categorized according to their geographic locations. The official declaration of war came on October 7, 2023, a non-trading day. Consequently, October 9, 2023, is designated as the event day in this study. The data was gathered between January 1, 2023, and December 31, 2023, with an estimation period of 140 days taken into account to minimize bias.FindingsAsymmetric response is shown among the nations due to their economic standing, geographic proximity and trading links with Israel. While Austria, Greece, Egypt, Palestine and Israel had the greatest negative effects, Argentina, Japan and Chile saw significant beneficial effects. The remaining nations had little effect. The market quickly adjusted itself, eliminating anomalous returns.Research limitations/implicationsTaking into account the topic's criticality, the current work has certain limits. The study has used the daily data to limit its reach to the stock market exclusively. In the future, academics can combine high-frequency stock market data with data from other macroeconomic variables, such as currency or different commodities markets, to further their research. Furthermore, a cross-national comparison of the impact in terms of direction and intensity regarding developing global groups such as I2U2, LEVANT, BRICS, MIKTA, SCO, NATO, SAARC and OECD can provide a more comprehensive understanding in this context. To gain insight into the durability and adaptation of financial systems over time, longitudinal studies could be conducted to monitor the long-term effects of geopolitical crises on the stock markets of trading partner countries.Practical implicationsBy better managing investment portfolios and evaluating potential risks associated with trading partners involved in such conflicts, investors and businesses can lessen the impact of geopolitical tensions on stock market performance. These results contribute to our understanding of how geopolitical conflicts affect stock markets.Originality/valueThis research provides an extensive analysis of the global impact of Israel-Hamas tensions on stock market volatility by taking into account trading partners. This allows for the investigation of how various market structures and economic systems react to geopolitical turmoil. The present study is one of the first attempts to look into how disturbances in one region might affect continents to better understand the dynamics of global trade and economic interdependencies.

Stock exchange operations in an anti-crisis management system of the enterprise

Today, in the process of building an effective system of anti-crisis management of the enterprise, more attention should be paid to such less common, but highly effective tools as stock transactions. Anti-crisis management is a certain set of strategic measures and tactical actions aimed at identifying, preventing and overcoming crisis phenomena in the company's activities, as well as impulses that potentially threaten the development of crisis phenomena in the future. The main directions of action are the following: development of the general anti-crisis strategy of the enterprise, ensuring the financial stability of the enterprise, implementation of the risk management system, restructuring of the enterprise and its business processes, personnel and communications management, increasing the efficiency of the marketing system, etc. Speaking about the place of stock exchange operations in the system of anti-crisis management of the enterprise, it should be noted that they can be considered as a tool in the middle of some of the above measures, namely optimization of business processes, improvement of the level of communications and activation of marketing. In all these aspects, the use of exchange operations can be effective. In our opinion, transactions with goods and derivative financial instruments require the main attention. Speaking about the optimization of business processes, the following advantages of cooperation with stock exchange institutions can be distinguished: guaranteed replenishment of production stocks with raw materials and materials of the required quality and quantity due to the conclusion of term exchange agreements for their supply, the forecast level of prices for raw materials and materials, which is fixed during the conclusion of exchange agreements , clearly defined conditions of supply. Access to the stock market also has a positive effect on the level of business communications, because it is the stock exchange that maximally concentrates all interested parties regarding specific types of goods, which contributes to the intensification of business activity. Exchange operations can also be considered as a highly effective tool for activating the marketing activities of the enterprise. In addition to the purchase of raw materials on the stock exchange for your activity, you can use the stock market for the sale of goods manufactured by the enterprise. In this way, the company can guarantee itself future sales in a certain forecasted price range, and accordingly, reasonable planning of the company's performance indicators, cash flows is possible, therefore, it becomes possible to manage insolvency, which is the main crisis impulse for the company.

Environmental Impact of Agricultural Land Transfer in China: A Systematic Review on Sustainability

Farmland holding fragmentation facilitates more extensive use of agricultural chemicals, which harm the natural environment. Agricultural land transfer in China aims to consolidate agricultural holdings, promoting economies of scale and addressing socio-economic and environmental concerns. This systematic review aims to examine the impact of agricultural land transfer on the environment. The review evaluates 60 empirical research articles retrieved through the Web of Science and SCOPUS databases, which discuss the relationship between agricultural land transfer and the environment. The findings indicate that agricultural land transfer has both positive and negative impacts on the environment. Farmers who engage in land rental and adopt sustainable agricultural practices, including the utilization of organic fertilizers, implementation of conservation measures, and application of efficient carbon reduction techniques, have demonstrated a notable positive influence on the environment. The lack of regulatory mechanisms concerning agricultural land transfer, including non-adjacent agricultural land transfer and large-scale farmers’ improper chemical utilization, causes significant negative environmental consequences such as biodiversity loss and ecosystem destruction. As such, we recommend innovative institutional developments addressing spatial and temporal considerations, land use, market systems, and household conditions to reconcile the links between agricultural land transfer policy and environmental outcomes. We urge continued research into the multidimensional and potential effects of agricultural land transfer to facilitate better-informed policy-making.

The Paradox of Women Ownership of Land and Gender Equality in Sub-Saharan Africa: Channels and Obstacles

ABSTRACT The goal of this article is to provide an in-depth analysis of the channels through which women acquire land in sub-Saharan Africa (SSA), the inherent obstacles and the relevance of land ownership to gender equality and women’s economic and social outcomes; and provide suggestions to inform effective gender-sensitive land policies. Emphasis of this study is on the inheritance channel through birthright with a conviction that it is socially and economically empowering. The descriptive analysis shows that the proportion of women who own land in SSA is 40% points lower than that of men regardless of how the land was acquired, whereby about 30% of women own land in SSA, compared to 70% of men. Nonetheless, women are more likely to acquire land either through purchase from the market system or marriage, and even then, their rights of ownership are usually very limited and precarious compared to the rights of men.

Low-Carbon Distributed Optimal Operation of Integrated Energy System Considering Wind and Solar Uncertainty

To ensure the supply and demand balance of integrated energy systems (IES) in the electric-carbon market and solve the complicated interest relationship among participants in the system, a distributed optimal scheduling model based on the extended carbon emission flow theory of integrated energy systems was proposed. Firstly, hydrogen energy production and utilization devices are introduced into the energy supply side to establish an expanded carbon emission flow model of the hydrogen-energy coupling integrated energy system based on carbon emission flow theory. Then, the fuzzy membership function is used to characterize the uncertainty of wind and light output. The distributed optimization algorithm based on goal cascade analysis realizes the decoupling of the integrated energy service provider and the user. This achieves the independent solution of the integrated energy service provider. A numerical example is given to verify that the proposed strategy can realize the stable and optimal operation of the integrated energy system in an uncertain environment.

The Application of Differentiated Pricing Strategy in M&A Practice of Listed Companies

In recent years, with the continuous active market of listed companies M&A and reorganization, the phenomenon of differentiated transaction pricing M&A is very common. In order to quickly shorten the transaction process, the initial design of the transaction plan needs to pay attention to the demands of the transaction parties, and the application of differentiated pricing strategy meets the diversified needs of the transaction parties. Based on the historical wave of M&A and the development status of Chinese listed companies, this paper analyzes the applicability and defects of M&A pricing of Chinese listed companies from the point of view of the core issue in the M&A process. This paper studies the pricing problem from two aspects. First, starting from the deterministic system, it analyzes the pricing of M&A enterprises under the perfect market system. The second is from the actual situation of China, the use of AMPS model for analysis. The research results show that the practice of differentiated pricing strategy of listed companies can not only deepen the understanding of the role of corporate governance in M&A, but also promote the effective risk control and profit maximization of listed companies. The research significance is to have a further understanding of the M&A pricing of China's joint-stock enterprises.

An empirical analysis of the development of China’s rural market economy system

ABSTRACT This paper presents a comprehensive study conducted from 2000 to 2021, utilizing a 14-indicator index to measure China’s rural Marketization economic development. The indicators encompass four dimensions: rural market subjects, rural market systems, rural land property rights, and government macroeconomic regulation and control. The research covers national and regional levels, providing insights into the following key findings: Firstly, China has witnessed a consistent improvement in the level of rural market economic development across national, regional, and provincial tiers. This progress can be predominantly attributed to advancements in rural land property rights, characterized by enhanced land tenure security and a significant reduction in land disputes. Secondly, Western China has maintained a synchronized development pace with central and eastern regions, resulting in relatively minor developmental disparities. Nevertheless, the progression of rural market subjects in western China remains a limiting factor in further enhancing rural market economic development. Simultaneously, government macroeconomic regulation and control act as a constraining element in driving nationwide rural market economic development. Given the persistent imbalance in regional development, concerted efforts should be made to gradually narrow the developmental gap among the western, central, and eastern regions at both the rural market entity and government macro-control levels.

Farmers’ motivational factors for medicinal plant production in the southwestern region of Bangladesh

Medicinal plants (MPs) generate cash income and save millions of people in Bangladesh. The aim of this study is to identify farmers’ motivational factors to cultivate MPs. This study is based on primary data collected from 196 sample households from two MP-growing districts of Bangladesh. Three MPs, namely, Aloe vera, Bombax ceiba, and Withania somnifera, were considered for this study. Principal component analysis (PCA), the z test, the Wilcoxon signed-rank test and factor analysis (FA) were used in this study. The results showed that household size and male-headed household status are driving socioeconomic factors. Ownership of water pumps, number of rooms in the house, access to contract marketing, and off-farm income are significant economic factors encouraging households to cultivate MPs. Farming experience, scientific knowledge, access to high land and access to loamy land are significant biophysical factors motivating farmers to cultivate MPs. More technical support and institutionalized contract marketing systems should be continued and established for the sustainability of MP cultivation.

How to achieve targeted advertising with the e-commerce platform’s membership system?

Targeted advertising has been extensively researched and utilized, yet it remains a challenge for the majority of small and medium-sized enterprises (SMEs) to effectively implement. To tackle this issue, e-commerce platforms have established member-oriented marketing windows that attract high-quality merchants and consumers, creating new opportunities for SMEs. Unlike traditional mass advertising (MA) in public windows, SMEs can achieve targeted advertising (TA) marketing to member and non-member groups separately by joining the membership marketing system. Two typical advertising cost-bearing structures are included for the platform’s membership marketing system: the Platform-Bearing-Cost (PBC) and the Merchant-Bearing-Cost (MBC) mechanisms. The results show that, regardless of the cost-bearing mechanism, the narrow fee gap between the two marketing windows leads to a higher advertising level and advertising investment for members under TA. Moreover, we identify the criteria under which the merchant adopts TA: a limited cross-purchase for the members in public windows. Furthermore, a sufficiently low members’ cross-purchase coefficient in public windows contributes to a TA win–win outcome for the platform and the merchant. Nevertheless, the platform does not always benefit from the merchant’s adoption of TA, which has inspired us to refine the platform’s membership marketing system further. Two viable options are proposed for consideration: discount adjustment and product screening. The former, which is a strategic adjustment of member-only discounts, is designed to induce merchants to adopt the ad format that aligns with the platform’s expectations. The latter, which is a set of rigorous entry criteria, is intended to permit only those products that are in high demand to participate.

Volume and Frequency of Transactions that Influence Share Prices are Mediated by Financial Performance and Moderated by Dividend Policy

One of the benchmarks for a country's progress is the existence of the Capital Market. The capital market is a gathering place for public companies operating in both primary and secondary markets. The secondary market in the capital market is a preference for people and organizations to invest. Share prices are a consideration for investors in determining investment decisions. The online trading system in the capital market is considered an efficient step and makes it easier to accelerate transactions, both buying and selling. The impact of transaction speed allows transaction volume and frequency to increase. The increase in transaction volume and frequency can only be seen in terms of technical factors, but fundamental factors in investing in the capital market also need to be considered. In this study, the researcher tried to include financial performance as well as a moderating variable which is proxied by dividend policy which is thought to influence stock prices. The results of research model 1 show an R-squared value of 0.487204. This shows that transaction volume, transaction frequency and DPR contributed 48.72% to PBV, while the remaining 51.28% was the contribution of other variables besides the independent variables studied. Meanwhile, Model 2 shows an R-squared value of 0.956943. This shows that PBV, Transaction Volume, Transaction Frequency and DPR contribute to SP amounting to 95.69% while the remaining 4.31% is the contribution of other variables besides the independent variables studied.

CEEC stock markets in the post-communist era: evolutions and convergences

ABSTRACT The political regimes that emerged from the 1989–1990 transitions needed a strong financial market system to support the economic transformation of previously -centralized communist regimes. In this way, the banking system had to attract foreign investment to build a strong system that was able to lend and create a resilient economy for its private and public sectors. To understand the important role that stock markets play in modelling countries’ economic functioning, this paper explores and reviews the effects of stock market reopening in CEE countries. The data analysis shows that indeed, if referring to financial indicators, the economies of communist countries reached those in Western Europe. Nonetheless, the effects of the equal distribution of financial success remain unclear.

A multi-stage techno-economic model for harnessing flexibility from IoT-enabled appliances and smart charging systems: Developing a competitive local flexibility market using Stackelberg game theory

The increasing integration of renewable energy sources with power systems has led to greater uncertainties, heightening the need for more flexible services. Demand-side resources can provide significant flexibility cost-effectively, making it crucial to design new business models to harness their flexible capacities. Hence, this paper introduces a three-stage techno-economic framework designed to enhance the exploitation of flexible capacities from demand-side resources such as Internet-of-Things (IoT)-Enabled Appliances (IEAs), Battery-Integrated Rooftop Solar Panels (BIRSPs), and Electric Vehicle (EV) smart charging systems in the local flexibility market. The proposed framework operates in three stages. First, smart homes with IEAs, BIRSPs, and smart charging systems assess their flexibility and report it to their Microgrid (MG) operators. Next, MG operators optimize strategies to maximize market returns and report capacities to the Distribution System Operator (DSO). Finally, the DSO manages flexibility transactions based on MG inputs. A Stackelberg game theory model using a gradient-based method updates the coupling variables between market parties, ensuring convergence in the second and third stages within a decentralized space with limited information sharing. Implemented on a modified IEEE 69-node distribution system, the model fully utilizes the potential of smart homes, including IEAs, BIRSPs, and smart charging systems in the local flexibility market. It reduces the Upstream Network (UN) share in the local flexibility market by 56.86% and decreases DSO costs for energy balancing by 22.36%.

Disability and marketing: a bibliometric analysis and systematic literature review

The needs of people with disabilities have been largely overlooked in the marketplace and in the development and promotion of products and services. As the marketing system has the potential to drive changes in the education system, industry, market, and society, a more grounded and comprehensive understanding of the scholarly debate on disability is essential for advancing academic knowledge and marketing practice. Therefore, this paper provides a bibliometric analysis and systematic literature review on disability and marketing, based on 68 articles published between 1985 and 2022. After identifying the most prominent journals, authors, countries, and research methods employed, a qualitative content analysis is used to thematically map this domain of research. Descriptive data provide evidence of a recent surge in marketing studies addressing disability, which has received increased attention since 2020. Existing research has been primarily driven by studies on tourism, services, and social marketing, while other fields remain largely unexplored. In recent years, there has been growing scholarly interest in marketing communications and the representation of disability; however, the focus on barriers and accessibility has hindered the advancement of the knowledge base regarding the social inclusion of people with disabilities from a marketing perspective. Based on its main results, the paper identifies possible avenues for further research, which may also offer valuable insights for policymakers and marketing practitioners interested in the inclusion of people with disabilities in society and the market.

Hayek, Buchanan and the justification of the market

AbstractThis paper discusses the work of two twentieth‐century liberal economists, Friedrich Hayek and James Buchanan, who have made lasting contributions to our understanding of the role of the market in a free society. I argue that they offer significantly different but complementary visions of the value of the market as a system of individual freedom. Hayek's vision is of the price system as a marvel of spontaneous order which solves a fundamental economic problem – that of making efficient use of a totality of knowledge that is divided between individuals. Buchanan's vision is of the market as a space in which individuals are free to make voluntary exchanges. In his words, ‘this is all that there is to it’: the market is not a solution to any collective problem. These visions have a common blind spot. Both writers recognise the need for programmes of social insurance and consider how they should structured so as to be as compatible as possible with the workings of a market economy and a liberal democracy. But, I argue, neither sees the full importance of social insurance in a justification of the market system.
