Collaborative Filtering(CF) is a well-known technique in recommender systems. CF exploits relationships between users and recommends items to the active user according to the ratings of his/her neighbors. CF suffers from the data sparsity problem, where users only rate a small set of items. That makes the computation of similarity between users imprecise and consequently reduces the accuracy of CF algorithms. In this article, we propose a clustering approach based on the social information of users to derive the recommendations. We study the application of this approach in two application scenarios: academic venue recommendation based on collaboration information and trust-based recommendation. Using the data from DBLP digital library and Epinion, the evaluation shows that our clustering technique based CF performs better than traditional CF algorithms.

Service composition is an effective approach for large-scale multimedia delivery. In previous works, user requirement is represented as one fixed functional path which is composed of several functional components in a certain order. Actually, there may be several functional paths (deliver different quality level multimedia data, e.g., image pixel, frame rate) that can meet one request. And due to the diversity of devices and connections in pervasive environment, system should choose a suitable media quality delivery path in accordance with context, instead of one fixed functional path. This paper presents a deep study of multimedia delivery problem and proposes an on-line algorithm LDPath and an off-line centralized algorithm LD/RPath respectively. LDPath aims at delivering multimedia data to end user with lowest delay by choosing services to build delivery paths hop-by-hop, which is adapted to the unstable open environment. And LD/RPath is developed for a relatively stable environment, which generates delivery paths according to the trade-off between delay and reliability metrics, because the service reliability is also an important fact in such scenario. Experimental results show that both algorithms have good performance with low overhead to the system.

Spatial Hypertext Wiki (ShyWiki) is a wiki which represents knowledge using notes that are spatially distributed in wiki pages and have visual characteristics such as colour, size, or font type. The use of spatial and visual characteristics in wikis is important to improve human comprehension, creation and organization of knowledge. Another important capability in wikis is to allow machines to process knowledge. Wikis that formally structure knowledge for this purpose are called semantic wikis. This paper describes how ShyWiki can make use of spatial hypertext in order to be a semantic wiki. ShyWiki can represent knowledge at different levels of formality. Users of ShyWiki can annotate the content and represent semantic relations without being experts of semantic web data description languages. The spatial hypertext features make it suitable for users to represent unstructured knowledge and implicit graphic relations among concepts. In addition, semantic web and spatial hypertext features are combined to represent structured knowledge. The semantic web features of ShyWiki improve navigation and publish the wiki knowledge as RDF resources, including the implicit relations that are analyzed using a spatial parser.

J'ai lu les titres et articles de presse à propos d'Asia Argento et de sa supposée agression contre Jimmy Bennett. Ça sent le traquenard à plein nez. 

Le type assure avoir été agressé sexuellement par l'actrice à l'âge de 17 ans. Il se fout de la gueule de qui, le petit traumatisé ? La prétendue agression ne l'empêchait pas de titrer quelques semaines après que "Maman" lui manquait. Pour la petite histoire, les deux acteurs jouent à la mère et au fils depuis qu'ils ont tourné ensemble dans un film alors que Jimmy avait 7 ans et qu'Asia incarnait sa ...

Regain d'intérêt pour l'actualité, méfiance toujours vive, place croissante des réseaux sociaux: ce sont quelques-uns des enseignements du baromètre annuel sur la confiance des Français dans les médias publié lundi par le journal La Croix.

. Actu: le rebond

Fait marquant de ce baromètre réalisé depuis 1987: le regain d'intérêt pour l'actualité. 76% des sondés (1.500 majeurs interrogés par internet ou téléphone selon la méthode des quotas) disent la suivre "avec un grand intérêt", contre 62% l'an passé.

"C'est le cinquième plus haut niveau en 35 ans", a souligné Jean-Christophe Ploquin, rédacteur en chef de La Croix, lors d'une conférence de presse. Cette proportion est cependant moindre chez les moins de 35 ans (66%).

En outre, quatre sondés sur dix disent s'intéresser davantage à l'actu qu'il y a quelques années. Cela coïncide avec "une actualité riche en 2022" (Ukraine, présidentielle en France...) après la période du Covid, a commenté Guillaume Caline, de l'institut Kantar Public, qui réalise ce baromètre.

C'est toutefois à nuancer par le fait qu'un sondé sur cinq (21%) s'y intéresse moins qu'avant, et même un sur trois (33%) chez les moins de 35 ans.

Et la moitié des sondés (51%) ressent "souvent de la lassitude" envers l'actualité, la fameuse "fatigue informationnelle" pointée par plusieurs études récemment.

. Trop ou pas assez ?

Le Mondial de football au Qatar (pour 48% des sondés), la mort de la reine d'Angleterre (43%) et la pénurie de carburant (40%): voilà les trois sujets dont les médias ont trop parlé en 2022.

A l'inverse, 51% jugent que les médias n'ont pas assez parlé du débat sur la fin de vie. Selon M. Caline, cela montre "l'intérêt des Français pour les sujets susceptibles de les toucher directement".

Le traitement de la guerre en Ukraine suscite des avis partagés: 41% pensent que les médias en ont parlé au juste niveau et 38% qu'ils en ont trop parlé.

. La télé centrale

Journaux télé, radio, chaînes info, sites internet, quotidiens papier, réseaux sociaux: chaque jour, les Français utilisent en moyenne près de 4 canaux pour s'informer.

Mais, dans cette "multiplicité des sources d'info", la télé "garde une place centrale", selon M. Caline. Ainsi, les JT sont le canal que les sondés privilégient pour s'informer au quotidien, quel que soit l'âge (35% sur l'ensemble du panel).

Chez les 18-24 ans, les réseaux sociaux arrivent deuxièmes, alors que cette place est occupée par les chaînes info dans toutes les autres classes d'âge.

. Méfiance, toujours

Même si le jugement est moins sévère que l'an dernier, la perte de confiance reste une tendance de fond. Plus de la moitié des sondés (54%) pense que, "la plupart du temps, il faut se méfier de ce que disent les médias sur les grands sujets d'actualité".

Pour autant, "ce réflexe de méfiance" existe surtout quand on considère les médias "de manière globale", en tant qu'"institution", a pondéré M. Caline: "Pris isolément, c'est bien moins négatif".

Ainsi, parmi les sondés qui s'informent via les JT, 73% leur font confiance. Cette proportion est aussi de 73% pour la radio, 66% pour les quotidiens nationaux mais seulement 46% pour les émissions d'actualité et de divertissement à la télé et 40% pour les influenceurs.

Par ailleurs, l'image des journalistes reste dégradée: 59% des sondés pensent qu'ils ne résistent pas aux pressions politiques et 56% à celles de l'argent.

. Jeunes et réseaux

Les réseaux sociaux "ont fait leur trou" comme source d'information, "notamment chez les plus jeunes", a noté M. Ploquin. Toutes générations confondues, 35% des sondés les utilisent quotidiennement dans ce but.

Paradoxalement, seuls 36% de ceux qui s'informent sur les réseaux leur font confiance.

Et le rapport à cette source d'information met en évidence "un fort clivage générationnel", selon M. Caline.

Ainsi, après 35 ans, 6 sondés sur 10 pensent que la diffusion sur les réseaux d'informations par "des personnes qui ne sont pas des médias ou des journalistes" est une mauvaise chose.

Une proportion qui s'inverse chez les plus jeunes: la moitié des moins de 35 ans juge au contraire que c'est une bonne chose.

La Bourse de New York a conclu en hausse lundi, tirée par la technologie, à l'entame d'une semaine chargée en résultats d'entreprises où les investisseurs semblent enclins à davantage d'optimisme.

L'indice Dow Jones a avancé de 0,76% à 33,629,56 points, le Nasdaq, à dominante technologique, a grimpé de 2,01% à 11.364,41 points et l'indice élargi S&P 500 a pris 1,19%, repassant au-dessus des 4.000 points, à 4.019,81 points.

"Les marchés se focalisent sur les résultats d'entreprises et même si jusqu'ici ils sont, à mon avis, un peu décevants, les actions se comportent bien", a noté Hugh Johnson, de la firme de conseil économique Hugh Johnson Economics, soulignant les meilleures performances des secteurs de la technologie et des dépenses facultatives.

Pas moins de 11 sociétés membres de l'indice Dow Jones, soit un tiers d'entre elles, vont publier cette semaine leurs résultats trimestriels et souvent annuels.

Dès mardi sont attendus notamment Johnson and Johnson, 3M, General Electric et Microsoft. Mercredi, les investisseurs guetteront Boeing et Tesla.

Mais, selon M. Johnson, c'est surtout l'attitude à venir de la banque centrale américaine (Réserve fédérale ou Fed) qui motivait l'humeur du marché. Les investisseurs "penchent vers l'idée que la Fed va lever le pied sur les hausses des taux d'intérêt, ce qui est synonyme de meilleurs temps économiques, de meilleurs résultats d'entreprises et de meilleurs cours des actions", a-t-il résumé.

La Fed, qui réunit son Comité monétaire la semaine prochaine, se dirige, à en croire plusieurs de ses membres, vers un relèvement moindre des taux d'un quart de point de pourcentage, contre un demi-point en décembre.

"La grande attente désormais, pour la Réserve fédérale, est qu'elle relève ses taux de seulement un quart de point de pourcentage en février mais aussi en mars", a commenté M. Johnson.

"De plus, d'après l'évolution des produits à terme basés sur les fonds fédéraux, les investisseurs commencent à penser que la Fed va envisager une baisse des taux au dernier trimestre 2023", a-t-il assuré.

Selon lui, le marché penche donc "légèrement vers l'optimisme et cela se voit dans la performance des actions".

Du côté des valeurs, Salesforce a été recherchée (+3,09%), après l'annonce d'une forte augmentation de la participation dans le groupe informatique du fonds d'investissement activiste Elliott Management.

Elliott dispose désormais d'une participation de "plusieurs milliards de dollars" au capital du groupe de logiciels, a-t-on précisé de source proche, ce qui représenterait un investissement majeur en comparaison de sa participation jusqu'ici.

Spotify, le numéro un mondial des plateformes audio, groupe suédois coté à Wall Street, a gagné 2,08% à 99,95 dollars après avoir annoncé la suppression de 600 emplois, soit 6% de ses effectifs, dernier épisode d'une série de grands licenciements chez les géants du Net pour réduire leurs coûts.

Le titre du site de ventes en ligne d'ameublement Wayfair s'est envolé de 26,86% à 59,36 dollars, après que sa décision de réduire ses coûts et ses effectifs a entraîné la publication d'une note favorable de la part d'analystes bancaires.

Le groupe, très prospère aux Etats-Unis pendant la pandémie, avait annoncé vendredi qu'il allait se défaire de 10% de son personnel, soit 1.750 emplois. L'action avait déjà gagné 20% dans la foulée de cette annonce.

Les investisseurs ont modestement réagi à l'annonce d'un élargissement d'un partenariat entre Microsoft et le spécialiste de l'intelligence artificielle OpenAI, créateur du robot conversationnel ChatGPT, moyennant un investissement de "plusieurs milliards de dollars". L'action Microsoft a avancé de 0,98% à 242,58 dollars.

Tesla a gagné 7,74% à 143,75 dollars, dans l'attente de ses résultats mercredi et alors que son patron Elon Musk est revenu lundi à la barre à San Francisco au procès où il est accusé de fraude par des investisseurs pour avoir tweeté il y a plus de quatre ans qu'il comptait sortir le constructeur automobile de la Bourse.

Le fabricant de semi-conducteurs AMD a bondi de presque 9,22% grâce à une bonne note d'analystes bancaires.

Sur le marché obligataire, les rendements sur les bons du Trésor à dix ans se tendaient légèrement à 3,52% contre 3,47% vendredi.

(Belga) Le taux de cellules commerciales vides dans le centre-ville carolo est tendanciellement à la baisse, a indiqué lundi soir lors du conseil communal de la Ville de Charleroi Babette Jandrain, l'échevine carolo du Commerce en réponse à une question qui lui était adressée.

Selon l'élue, qui a indiqué reprendre les chiffres de l'Association de Management du Centre-Ville (AMCV), le taux actuel de cellules commerciales vides dans l'intra-ring carolo est de 29% contre 33,6% en 2020. Et ce malgré le Covid et la crise énergétique qui ont mis en difficulté l'activité commerciale dans les grandes villes. Si le taux de cellules commerciales vides reste élevé à Charleroi, il n'en reste pas moins que la situation a tendance à s'améliorer, a indiqué Babette Jandrain. Les chiffres donnés par l'échevine ont été constatés par la conseillère communale du PTB Sofie Merckx, évoquant une situation de "désolation" concernant le quartier de la Ville Basse et interrogeant par ailleurs la volonté de la Ville de faire de certaines cellules vides des logements. (Belga)

(Belga) Sept personnes ont été tuées lundi lors d'une double fusillade près de San Francisco, en Californie, ont indiqué les médias américains sur la base des déclarations de la police locale.

Le suspect a été arrêté, a annoncé sur Twitter le bureau du shérif du comté de San Mateo, qui comprend la ville de Half Moon Bay où ont eu lieu les drames. "Il n'y a plus de danger pour la population à cette heure", a-t-il assuré. Les deux fusillades sont intervenues dans des exploitations agricoles proches l'une de l'autre, ont précisé les médias. Cette nouvelle tuerie intervient moins de 48 heures après qu'un tireur a tué 11 personnes dans un club de danse près de Los Angeles. (Belga)

The current advertising push methods have low accuracy and poor advertising conversion effects. Therefore, a Weibo marketing advertising push method based on social network data mining is studied. Firstly, establish a social network graph and use graph clustering algorithm to mine the association relationships of users in the network. Secondly, through sparsisation processing, the association between nodes in the social network graph is excavated. Then, evaluate the tightness between user preferences and other nodes in the social network, and use the TF-IDF algorithm to extract user interest features. Finally, an attention mechanism is introduced to improve the deep learning model, which matches user interests with advertising domain features and outputs push results. The experimental results show that the push accuracy of this method is higher than 95%, with a maximum advertising click through rate of 82.7% and a maximum advertising conversion rate of 60.7%.

This paper aims to analyse the effectiveness of cost control oriented enterprise financial risk management. Firstly, it analyses the importance of enterprise financial risk management. Secondly, the position of cost control in enterprise financial risk management was analysed. Cost control can be used to reduce the operating costs of enterprises, improve their profitability, and thus reduce the financial risks they face. Finally, a corporate financial risk management strategy is constructed from several aspects: establishing a sound risk management system, predicting and responding to various risks, optimising fund operation management, strengthening internal control, and enhancing employee risk awareness. The results show that after applying the proposed management strategy, the enterprise performs well in cost control oriented enterprise financial risk management, with a cost accounting accuracy of 95% and an audit system completeness of 90%. It can also help the enterprise develop emergency plans and provide comprehensive risk management strategy coverage.

Access to quality healthcare is a fundamental right but unfortunately, India suffers from gender disparities in healthcare access. Telemedicine has the potential to improve access to healthcare services for women by eliminating traditional barriers. Therefore, our research aims to investigate the factors influencing the adoption of telemedicine among Indian women. This study has collected 442 responses and analysed them through structural equation modelling. The result indicates a strong and positive connection between the willingness to adopt telemedicine services and factors like performance expectancy, perceived benefits, e-health literacy, and perceived reliability. Notably, perceived reliability emerges as the most impactful predictor, closely followed by perceived benefits, while factors like effort expectancy and user resistance show no significant influence. This underscores the pivotal role of reliability and perceived benefits in shaping women's inclination toward adopting telemedicine. The study provides practical insights for telemedicine providers and policymakers to customise strategies and policies for effective promotion.

Although artificial intelligence provides a new method to gather, process, analyse data, generate insights, and offer customised solutions, such methods could change how marketers deal with customers, and there is a lack of literature to portray the application of artificial intelligence in marketing. This study aims to recognise and portray the use of artificial intelligence from a marketing standpoint, as well as to provide a conceptual framework for the application of artificial intelligence in marketing. This study uses a systematic literature review analysis as a research method to achieve the aims. Data from 142 articles were extracted from the Scopus database using relevant search terms for artificial intelligence and marketing. The systematic review identified significant usage of artificial intelligence in conversational artificial intelligence, content creation, audience segmentation, predictive analytics, personalisation, paid ads, sales forecasting, dynamic pricing, and recommendation engines and the bibliometric analysis produced the trend in co-authorship, citation, bibliographic coupling, and co-citation analysis. Practitioners and academics may use this study to decide on the marketing area in which artificial intelligence can be invested and used.

Supply chain management practices are vital for success and survival in today's competitive Indian retail market. The advent of COVID-19 pandemic necessitates a digital disruption in retail supply chain management centred on efficient technology like blockchain in order to enhance supply chain performance. The present research aims to decipher the nature of associations between supply chain management practices, blockchain technology adoption and supply chain performance in retail firms. The research is based on primary survey of specific food and grocery retailers operating on a supermarket format stores in two Indian cities. The findings pointed towards the presence of significant and positive association of all the constructs with each other. Moreover, the mediating role of blockchain technology adoption was also revealed, i.e., it partially mediates the effects of supply chain management practices on supply chain performance.

This study investigates the effects of social media marketing efforts (SMME) on smartphone brand identification, attachment, association, and willingness to pay premium prices. A survey of 320 smartphone users who followed official social media handles managed by smartphone companies was conducted for this purpose. PLS-SEM was used to analyse the collected data. The findings demonstrated importance of SMME dimensions. According to the study's findings, the smartphone brand's SMMEs had significant impact on brand identification, brand association, and brand attachment. The results revealed that SMMEs had significant impact on willingness to pay the premium price. The findings also show that brand identification, attachment, and association mediated the relationship between SMMEs and willingness to pay a premium price. The findings of this study will be useful in developing social media marketing strategies for smartphones. This study demonstrates the use of social media marketing to promote mobile phones, particularly in emerging markets.

The prevalence of social media transforms e-business into social commerce and facilitates consumers' engagement in cross-cultural social commerce. However, social commerce operations encounter unpredictable challenges in cross-cultural business environment. It is vital to further investigate how contextual elements affect consumers' trust and their engagement when they are exposed to the complexity of cross-cultural business environment. The stimuli-organism-response paradigm is employed to examine how the two dimensions of social media usage influence consumers' engagement in cross-cultural social commerce. The current study surveyed 2,058 samples from 135 countries, and the regression analysis results illustrate the mechanism whereby informational and socialising usage of social media positively influences consumers' engagement in social commerce through consumers' trust toward social commerce websites. Additionally, the associations between two aspects of social media usage and consumers' trust towards social commerce are negatively moderated by cultural distance. Both theoretical and practical implications are also discussed.

Differential privacy is usually applied to location privacy protection scenarios, which confuses real data by adding interference noise to location points to achieve the purpose of protecting privacy. However, this method can result in a significant amount of redundant noisy data and impact the accuracy of the location. Considering the security and practicability of location data, an effective differential privacy protection method of location data based on perturbation loss constraint is proposed. After applying the Laplace mechanism under the condition of differential privacy to perturb the location data, the Savitzky-Golay filtering technology is used to correct the data with noise, and the data with large deviation and low availability is optimised. The introduction of Savitzky-Golay filtering mechanism in differential privacy can reduce the error caused by noise data while protecting user privacy. The experiments results indicate that the scheme improves the practicability of location data and is feasible.

Constrained programming is the concept used to select possible alternatives from an incredibly diverse range of candidates. This paper proposes an AI-assisted Backtracking Scheme (AI-BS) by integrating the generic backtracking algorithm with Artificial Intelligence (AI). The detailed study observes that the extreme dual ray associated with the infeasible linear program can be automatically extracted from minimum unfeasible sets. Constraints are used in artificial intelligence to list all possible values for a group of variables in a given universe. To put it another way, a solution is a way of assigning a value to each variable that these values satisfy all constraints. Furthermore, this helps the study reach a decreased search area for smart backtracking without paying high costs. The evaluation results exhibit that the IB-BC algorithm-based smart electricity schedule controller performs better electricity bill during the scheduled periods than comparison approaches such as binary backtracking and binary particle swarm optimiser.

In order to further improve the teaching quality of multimedia teaching in school daily teaching, a classroom facial expression emotion recognition model is proposed based on convolutional neural network. VGGNet and CliqueNet are used as the basic expression emotion recognition methods, and the two recognition models are fused while the attention module CBAM is added. Simulation results show that the designed classroom face expression emotion recognition model based on V-CNet has high recognition accuracy, and the recognition accuracy on the test set reaches 93.11%, which can be applied to actual teaching scenarios and improve the quality of classroom teaching.

We introduce a unique inductive bias to improve the reconstruction quality of Neural Radiance Fields (NeRF), NeRF employs the Fourier transform to map 3D coordinates to a high-dimensional space, enhancing the representation of high-frequency information in scenes. However, this transformation often introduces significant noise, affecting NeRF's robustness. Our approach allocates attention effectively by segregating channels within NeRF using attention-based gating units. We conducted experiments on an open-source data set to demonstrate the effectiveness of our method, which leads to significant improvements in the quality of synthesised new-view images compared to state-of-the-art methods. Notably, we achieve an average PSNR increase of 0.17 compared to the original NeRF. Furthermore, our method is implemented through a carefully designed special Multi-Layer Perceptron (MLP) architecture, ensuring compatibility with most existing NeRF-based methods.

The banking sector has experienced a substantial technological shift that has opened up new and better opportunities for its customers. Based on their technological expenditures, the study assessed the two biggest public Indian banks and the two biggest private Indian banks. The most crucial statistical techniques used to demonstrate the aims are realistic are bivariate correlations and ordinary least squares. This work aims to establish a connection between research and a technology index that serves as a proxy for operational efficiency. The results show that for both public and private banks, the technology index positively influences operational efficiency metrics like IT costs, marketing costs, and compensation costs. This suggests that when the technology index increases, so do IT, marketing, and compensation costs, even though it has been shown that the technology index favourably improves operational efficiency measures like depreciation and printing. This means that the cost to banks is high despite greater investment in technology for these activities.

The proliferation of technology and communication has resulted in increased digitalisation that includes digital payments. This study is aimed at unravelling the relationship between awareness of individuals about the digital payment system and customer satisfaction with digital payments. Two models were developed in this study. First model considers awareness → usage pattern → customer satisfaction. Second model considers usage pattern → customer satisfaction → perception of digital payments. These two alternative models were tested by collecting data from 507 respondents in southern India was analysed using the structural equation modelling. The results indicate that usage pattern acted as a mediator between awareness and satisfaction, and satisfaction acted as a mediator between usage pattern and consumers' perception of digital payments. The implications for theory and practice are discussed.

The intelligent financial sharing platform in the online realm is capable of collecting, storing, processing, analysing and sharing financial data through the integration of AI and big data processing technologies. However, as data volume grows exponentially, the cost of financial data storage and processing increases, and the asset accounting and financial profit data sharing analysis structure in financial sharing platforms is inadequate. To address the issue of data security sharing in the intelligent financial digital sharing platform, this paper proposes a data-sharing framework based on blockchain and edge computing. Building upon this framework, a non-separable task distribution algorithm based on data sharing is developed, which employs multiple nodes for cooperative data storage, reducing the pressure on the central server for data storage and solving the problem of non-separable task distribution. Multiple sets of comparative experiments confirm the proposed scheme has good feasibility in improving algorithm performance and reducing energy consumption and latency.

In order to reduce the challenges encountered by learners and educators in engaging in educational activities, this paper classifies learners' roles in virtual learning communities, and explores the role of behaviour characteristics and their positions in collaborative knowledge construction networks in promoting the process of knowledge construction. This study begins with an analysis of the relationship structure among learners in the virtual learning community and then applies the FCM algorithm to arrange learners into various dimensional combinations and create distinct learning communities. The test results demonstrate that the FCM method performs consistently during the clustering process, with less performance oscillations, and good node aggregation, the ARI value of the model is up to 0.90. It is found that they play an important role in the social interaction of learners' virtual learning community, which plays a certain role in promoting the development of artificial intelligence.

With the expansion of business scope, the environment faced by enterprises has also changed, and competition is becoming increasingly fierce. Traditional financial systems are increasingly difficult to handle complex tasks and predict potential financial risks. In the context of the digital economy era, the booming financial sharing services have reduced labour costs and improved operational efficiency. This paper designs and implements an intelligent financial sharing platform, establishes a fund payment risk early warning model based on an improved support vector machine algorithm, and tests it on the Financial Distress Prediction dataset. The experimental results show that the effectiveness of using F2 score and AUC evaluation methods can reach 0.9484 and 0.9023, respectively. After using this system, the average financial processing time per order decreases by 43%, and the overall financial processing time decreases by 27%. Finally, this paper discusses the role of intelligent financial sharing platform in accounting transformation and optimisation of production.

Physiological indicators are an important basis for reflecting the physiological health status of the human body and play an important role in medical practice. Association rules have also been one of the important research hotspots in recent years. This study aims to create a data mining system of association rules and artificial intelligence in biochemical indicators of sports training. This article uses Markov logic for network creation and system training, and tests whether the Markov logic network can be associated with the training system. The results show that the accuracy and recall rate obtained are about 90%, which shows that it is feasible to establish biochemical indicators of sports training based on Markov logic network, and the system has universal, guiding and constructive significance, ensuring that the construction of training system indicators will not go in the wrong direction.

This study investigates the well-being of healthcare professionals in India, with a specific focus on the detrimental effects of the pandemic on their mental and physical health, including stress, burnout, and fatigue. This research examines the roles played by calling, mindfulness, and compassionate love as essential resources in promoting the well-being of healthcare professionals. Utilising structural equation modelling (SEM), the results reveal a significant cause and effect relationship between calling, mindfulness, and compassionate love and their influence on overall well-being. Furthermore, the study identifies a noteworthy parallel mediation effect, demonstrating that mindfulness and compassionate love serve as mediators in the relationship between calling and well-being. This research offers practitioners invaluable insights into the effective utilisation of mindfulness and compassionate love practices to enhance the overall well-being of healthcare professionals.

This empirical study investigates the mediating role of two components of psychological capital (PsyCap), namely self-efficacy and optimism, in the context of the relationship between transformational leadership (TL), work engagement (WE), and innovative work behaviour (IWB). The study was conducted among IT professionals with a minimum of three years of experience employed in Chennai, India. Data collection was executed using a Google Form, and both measurement and structural models were examined using SPSS 25.0 and AMOS 23.0. The findings of this study reveal several significant relationships. Firstly, transformational leadership (TL) demonstrates a robust positive association with work engagement (WE). Furthermore, work engagement (WE) positively correlates substantially with innovative work behaviour (IWB). Notably, the study underscores that two crucial components of psychological capital, specifically self-efficacy and optimism, mediate the relationship between transformational leadership (TL) and work engagement (WE). These findings carry valuable implications for IT company managers. Recognising that transformational leadership positively influences both work engagement and employees' innovative work behaviour highlights the pivotal role of leaders in fostering a productive and innovative work environment within IT organisations.

The study investigated the influence of ebullient supervision on employee commitment in a Ghanaian public university through the mediating role of employee engagement. The simple random sampling technique was used to draw 302 administrative staff of the university to respond to the self-administered questionnaire on the constructs. Furthermore, the partial least square structural equation technique was deployed to test the research hypotheses in the study. The results showed that ebullient supervision had a significant positive relationship with employee commitment and employee engagement. The findings further revealed that employee engagement positively correlated with employee commitment. Finally, the study's findings established that employee engagement partially mediated the link between ebullient supervision and employee commitment. The study emphasised that various supervisors in a university's administration should create an environment that favours fun where subordinates can form ties with one another.

The supply chains of the Canadian forest products industry are largely dependent on accurate demand forecasts. The USA is the major export market for the Canadian forest products industry, although some Canadian provinces are also exporting forest products to other global markets. However, it is very difficult for each province to develop accurate demand forecasts, given the number of factors determining the demand of the forest products in the global markets. We develop multi-layer feed-forward artificial neural network (ANN) models for demand forecasting of the Canadian forest products industry. We find that the ANN models have lower prediction errors and higher threshold statistics as compared to that of the traditional models for predicting the demand of the Canadian forest products. Accurate future demand forecasts will not only help in improving the short-term profitability of the Canadian forest products industry, but also their long-term competitiveness in the global markets.

Intellectual assets, especially its relational forms, have become increasingly important to explain a firm's innovation. To examine relational forms of intellectual assets (IA), this study theoretically and empirically advances a concept of alliance management capability (AMC) to explain the value creation and capture aspects of a firm's innovation process. The concepts of value-creating alliance experiences (VCAE) and value capturing alliance experiences (VCPAE) were introduced in which a firm's ability to learn from these alliance experiences increases the firm's ability to discover and govern partnerships that bring the firm's innovations to market. Hypotheses were developed and empirically examined in the biotechnology industry. A contribution of this study is that a firm's VCAE and VCPAE introduce a greater 'openness' to a firm's innovation process. This openness enables a firm to better adapt and respond to the opportunities of the market and thus impact a firm's competitive advantage to innovate.

This article explores dual affiliated graduate students that conduct research involving both universities and firms, which we conceptualise as a form of academic engagement, e.g., knowledge networks. We explore what they do during their studies, and their perceptions about their contributions to the firm's capacities for technology and innovation. So far, university-industry interactions in engineering are less researched than other fields, and this qualitative study focuses upon one department of Electrical Engineering in Sweden. First, we define and describe how the partner firms and universities organise this research collaboration as a form of academic engagement. Secondly, we propose a conceptual framework specifying how graduate students act as boundary-spanners between universities and firms. This framework is used for the empirical analysis, when exploring their perceptions of impact. Our results reveal that they primarily engage in problem-solving activities in technology, which augment particularly the early stages of absorptive capacities in firms.

This study aimed to assess the level of GW in Jordanian university students and compare the level of awareness of students according to their academic level (high and low), faculty (science and humanities), gender (male and female), and year of study (first and final years). This study is quantitative research that provides a comprehensive view of GW in Jordanian universities. A total of 383 university students of currently registered undergraduate programs from six independent universities in Jordan were recruited. An online questionnaire covering three aspects of GW was sent to participants in December 2020. Inferential and descriptive statistics were used to analyse data. Participants had 'good' (67%) overall knowledge about GW, a 'very good' level of GW causes (81%), and a 'poor' level of knowledge about the GW impacts on humans and the environment (47%) and knowledge about GW possible solutions (59%). Significant differences were founded between males and females, students from scientific faculties and students from other faculties, students with higher academic achievement than lower achievement in the total GW knowledge. But no significant differences were between students in the first year and the final years.

The face of the hospitality sector in India is continuously changing and in times of career transitiveness, it is important to know the factors that support a successful career. The current research aims to explore the relationship between career planning, employee optimism, career adaptability and career satisfaction in the Indian hospitality sector. The study included 283 employees from Indian hospitality sector. Additionally, the study used SEM and bootstrap method to measure the dual mediating relationship between career planning, employee optimism dimensions, career adaptability dimensions, and career satisfaction in Indian setting. The results indicated that optimism dimensions and career adaptability dimensions partially mediate the relationship between career planning and career satisfaction in Indian hospitality sector. The study suggests useful implications for academia and industrial purpose. The limitations and future research avenues have been discussed. The study would contribute to the sparse literature on employee optimism, career planning, career adaptability and subjective career success. It would contribute to the social cognitive career theory (SCCT).
