In this paper, we propose a new neural network architecture for item recommendation with structural information. Our model, structural neural recommender (SNR) is based on neural networks and operates on a hierarchy paradigm, aiming to explore the effectiveness of incorporating different structural information for recommendation. Many recent state-of-the-art neural network based recommendation models exploit the nonlinear transformations for modeling the complex user-item interaction patterns and user historical behaviors, ignoring the item-item structural relationship. This structural information, however, is uncomplicated to derive and useful for inferring item characteristics. To utilize this information, SNR simultaneously learns representation from user-item interactions and item-item relationships. Empirical studies on eight real-world datasets demonstrate the effectiveness of incorporating such structural information, by outperforming classic and recent baselines. We also conduct detail ablation studies and hyper-parameter analysis to provide further understanding towards the behaviors of our model. Following the model development, we conduct a field experiment to demonstrate that the effectiveness of algorithmic recommender systems can further increase by using different types of message framing when communicating recommendations to consumers. Our results suggest that recommendations framed with a relevance appeal (e.g. “Top 5 brands for you”) are more effective in general, yet recommendations that are framed with a popularity appeal (“Top 5 most popular brands”) are more effective for customers who were acquired via social media (versus non-social media) advertising or for those who have stronger (versus weaker) social orientation.

A bibliometric analysis, spanning five decades of knowledge is employed with the aim of: (i) assessing core intellectual knowledge of international services research; (ii) examining the contribution of international services marketing to broader research disciplines; and, (iii) estimating forecasting trends for the most promising international services research directions.

Drawing from the uses and gratification theory (UGT), the study intends to investigate audiences’ motivation to watch Livestream and its influence on subscription and donation. The roles of viewers’ parasocial relationships and identification with live streamers were also examined. The results also indicate the presence of a mediation effect.

Food waste is a critical problem for many countries. Food producers and groceries often discard imperfect foods or food by-products that still contain nutritional value. To address this problem, some food manufacturers have turned to upcycling, that is, to convert otherwise discarded ingredients into new food products (e.g., cacao fruit pulp into crunch bites). Consumers’ acceptance of sustainable products is generally lower than that of conventional products due to quality concerns. We speculate that for upcycled food products, consumers’ perception of product quality may vary when different percentages of imperfect ingredients are integrated into the products. Drawing from schema congruity theory, this research examines how the usage of imperfect ingredients can impact the perceived quality of upcycled food products. The implications for marketing upcycled foods are discussed.

To successfully expand their business activities in overseas markets, small- and medium-sized enterprises (SMEs) must first acquire a thorough knowledge and understanding of prevailing environmental and market conditions. This study examines the crucial role that a learning orientation can play in the generation of relevant foreign market knowledge. It also investigates the impact of foreign market knowledge on strengthening internationalizing SMEs’ operational adjustment agility and market capitalizing agility, which in turn enhance firms’ international venture performance. Our empirical effort is based on data collected from 209 Nigerian industrial SMEs which internationalize their efforts. To test our research model and hypotheses we collected data by means of a survey conducted among Nigerian small- and medium-sized firms (i.e., employing 250 or less people) which internationalize their efforts and launch their products in B2B markets. The positive role of learning orientation, foreign market knowledge and organizational agility is confirmed by our results on driving international venture performance.

The rise of social media has brought the existence of “foodie” and “food bloggers” in the culinary business. The word “foodie” refers to those who highly favor and engage with food and spend a substantial amount of time collecting culinary experiences and visiting famous restaurants, while a food blogger is an individual or a foodie who uses a communication platform to share recipes and passion for food through reviews based on his or her experience. Culinary businesses use food bloggers to help promote their products and encourage consumers to try their products, which are believed to be effective as the viewers or the followers tend to take their recommendations.

To address the existential threat of climate change, it is important to study environmentally sustainable products and marketing strategies to promote such products. A repurposed product is created by transforming old objects into something of greater value that serves a different purpose. For example, transforming an old tie into a coffee cup sleeve or turning a discarded oil can into a drum. Thus, repurposed products are one form of waste reduction via reuse. Repurposed products have become popular in the marketplace. There is, however, little research on repurposed product consumption. Furthermore, Gen Z is a relatively unexplored population in past research on sustainable consumption. To address these research gaps, our study identified segments of Gen Zers based on their perceptions of repurposed products via a person-centered approach. Our results provide strategies for effective marketing of repurposed products. Implications for marketers are provided.

Augmented reality (AR) is a technology that overlays user surroundings with computer-generated images (Baek et al., 2016). It provides users with an enhanced view of their environment with digital content such as text, pictures, videos, three-dimensional (3D) objects, and even tactile and olfactory experiences (Du et al., 2022). This technology has significant potential for use in advertising, enabling realistic product visualisations and virtual product try-ons via social media (Baek et al., 2016).

The tourism industry specifically experienced distinct failing revenues and was an economic sector among those most rigorously influenced by the pandemic. In the gradual recovery period after the pandemic, the technology implementation in travel has been a great achievement for travel companies. This study is based on a systematic literature review to examine the ability of Virtual Reality (VR) and Geographic information systems (GIS) to serve as a facilitator of sustainable tourism development goals. The potential impact of VR and GIS within tourism will bolster the Sustainable Development Goals (SDGs) and will be conceptualized. The use of these technologies in connection to the SDGs can associate with SDG No. 8, SDG No.9, SDG No.11, and SDG No. 13, which are related to "decent work and economic growth", "industry, innovation, and infrastructure", "sustainable cities and communities", and "climate action."

Live streaming commerce is a novel form of an e-commerce platform, which works by establishing a temporary virtual community shared by streamers and customers in real time. With the popularity of live streaming shopping, many e-retailers adopted this new platform to promote their products in an effort to boost their sales volume. On the basis of signalling theory and social exchange theory (SET), this study proposes a research model to examine the informational signals and customer-streamer exchanges that two parties shared using live streaming platform. An online survey with 735 samples was collected through a professional online survey service platform (i.e., Wenjuanxing) to measure our model. Our results indicate that both service-centred signal (interaction quality) and product-centred signal (streamer credibility) have significant positive influences on customer evaluation of information quality. The results also denote that the received information quality acts as a significant predictor of customer engagement and buying tendency. Moreover, the results confirm the mediation role of customer engagement in predicting impulsive buying tendency, and the moderation effects of guanxi orientation on customer engagement and impulsive buying tendency. By synthesizing the preceding findings, theoretical and practical implications are discussed in the context of live streaming commerce.

This work presents four high-amplitude variable YSOs (≃3 mag at near- or mid-IR wavelengths) arising from the SPICY catalog. Three outbursts show a duration that is longer than 1 year, and are still ongoing. And additional YSO brightened over the last two epochs of NEOWISE observations and the duration of the outburst is thus unclear. Analysis of the spectra of the four sources confirms them as new members of the eruptive variable class. We find two YSOs that can be firmly classified as bona fide FUors and one object that falls in the V1647 Ori-like class. Given the uncertainty in the duration of its outburst, an additional YSO can only be classified as a candidate FUor. Continued monitoring and follow-up of these particular sources is important to better understand the accretion process of YSOs.

The words for the moon phase in the inscriptions on bronze wares in the Zhou dynasty are open to different interpretations, and the calculation of the moon phase dates clarifies the ambiguities of the bronze moon phase words. Calculation of the time interval between the calendar solunar dates in two bronze ware inscriptions can be made, because the calendar solunar dates (gan-zhi 干支) were in a constant cycle of 60 days. Calculation of the date interval between the two moon phases on the same two bronze ware inscriptions also can be made , because the moon phase is also in cycles. The narrative tradition in the inscriptions of the Shang and Zhou dynasties includes a date series: the day in the solunar cycle, the month and the year of a king’s reign, and the day in the moon phase cycle. By comparing whether the two intervals meet or not, one can verify whether the bronze moon-phase idioms are meaningful, and it can also be confirmed whether the chronology of the kings of Zhou compiled by the previous scholars is resonable and create a new chronology through iterative calculation. The time intervals calculated in this paper chronicle every imperial event from the Zhou dynasty to the Shang dynasty, which rebuild a new chronology for the Xia, Shang, and Zhou dynasties. All modern attempts are hindered by a basic assumption, that the bone calendar of the Shang Dynasty is the same as the bronze calendar of the Zhou Dynasty, but it is completely different from the bronze calendar of Zhou, when reading the Bronze Annals (this paper) alongside the Bone Annals (last paper) and as seen in Table 24. In addition, although the inscriptions related to the lunar phases are extremely difficult to understand, through computation, the records of three lunar eclipses on bronze vessels in the Zhou and Shang dynasties are newly recognized, which helps to reconstruct a new chronological list of the kings of Zhou.

Рrecipitation of platinum group metals (Rh, Ru, Pd, so-called MPG) from the melt essentially affects the reliability of installations for vitrification of high-level liquid radioactive waste (HLW). To date, it is difficult to find an approach which allows simultaneous recovery of all three metals. The aim of our work was to select a sorbent that would provide simultaneous up to complete recovery of given metals. The following inorganic materials were tested as sorbents – yellow blood salt (YBS).and hexacyanoferrates of iron, aluminum, copper and nickel. The degree of metal recovery was studied is influenced by the temperature and concentration of nitric acid. Only palladium was completely recovered using YBS. At the same time, specially prepared iron hexacyanoferrate (HCF-Fe) under optimal experimental conditions recovers almost all Pd and more than 95% and 90% of Rh and Ru, respectively. The behavior of fission products, including the main dose-forming components of HLW (Cs, Sr) and Mo, U, Ag, REE) in the course of MPG recovery was studied. The experiments were carried using both multicomponent model solutions and real raffinates. Options for further management of the recovered metals have been worked out. Thus, the proposed method of metal recovery seems promising for the development of a technology for the removal of MPG from nitric HLW during the reprocessing of the spent nuclear fuel (SNF) before vitrification. The recovered metals can be probably used in various technological processes. Also, this method can provide the MPG recovery from low-concentration tail solutions.

Since the beginning of the seventh century, Islamic law has played an essential role in protecting the personal, economic, judicial, and political rights of civilians during armed conflict. Fourteen centuries before the Universal Declaration of Human Rights was drafted in 1948, it had already initiated a human revolution consisting of a set of human principles. In addition, Islamic law has made a significant contribution to international humanitarian law (IHL). This paper focuses on two specific legal constructs in warfare: the definition of the combatant and the principle of distinction. This article comparatively examines how these two laws deal with different aspects of war that fall under jus ad bellum, jus in bello, and jus post bellum. A comparative analysis of the various elements and aspects of just war theory in Islamic and contemporary international law provides a much deeper understanding of its limitations. We can safely conclude that there is a unique relationship between the Islamic law of war and IHL.
