CRF component can help the network learn the constraint conditions of each word corresponding prediction label, improve the D-GRU method based word label prediction errors, and improve the accuracy of sequence annotation. The Transformer architecture of the ViT (Huge) model can extract the global feature information of the image, while CNN is better at extracting the local features of the image. Therefore, the ViT (Huge) Huge pre-training model and CNN pre-training model adopt the multi-modal feature fusion technology. Two complementary image feature information is fused by Bi-GRU to improve the performance of network classification. The experimental results show that the newly constructed Dxvnet-Vit-Huge (JFT) model achieves good performance, and the F1 values in the two real public data sets are 6.03% and 7.11% higher than the original DXVNet model, respectively.","PeriodicalId":292161,"journal":{"name":"Journal of Economics and Technology Research","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123369923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Keynes saw that the technical analysis of the role of confidence in decision making had been overlooked in economics. Keynes corrected this lacuna in the General Theory. Confidence was defined as a function of Keynes’s evidential weight of the argument, V, where V=V (a/h) =w,0?w?1,just as the term “very uncertain”, used three times on p.148 of the General Theory, was defined as a function of a slight amount of information, a definition that is identical to Keynes’s definition of “very uncertain” on p.310 of his A Treatise on Probability. w equaled the degree of the completeness of the relevant information upon which the probabilities were based. Keynes’s definition of V can be found on p.315 of his A Treatise on Probability in chapter 26, titled “The application of probability to conduct”. His discussion of the completeness of the evidence can be found on pp.313-315.The second major point was Keynes’s completely overlooked discussion of the reasonable calculation of probabilities, based on approximate and inexact measures like interval valued probability and his decision weight, c, which he called a conventional coefficient of weight and risk, c, versus the unreasonable calculation of probabilities based on strict or exact mathematical expectations calculations as advocated by Frank Ramsey. The heart of Ramsey’s theory is a reliance on betting quotients and mathematical expectations based on precise probability.","PeriodicalId":292161,"journal":{"name":"Journal of Economics and Technology Research","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123773818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, not so much is understood about the wider effects of sustainability practices on the ability of the SC to endure disruptions. The aim of this study was therefore to scrutinize the effect of sustainability practices on supply chain resilience in the development of a circular economy in Nigeria. This study was steered within the horizon of qualitative method with a philosophical research paradigm of constructivism. The study used twenty-one (21) Consumer Goods Firm in Nigeria as population and sample. Primary data was explored using key informant interview. Thematic analysis was used to analyze the data collected. The study reveals that sustainability practices contribute to supply chain resilience in the development of a circular economy. The research concluded that, cradle to cradle practice, environmental sustainability, economic sustainability, and social sustainability play a major role in ensuring resiliency of consumer goods firms’ supply chains especially in developing a circular economy. The outcome of this research is expected to lead to the development of a circular economy in Nigeria. The study will be of significance to Nigerian government, consumer goods companies, practitioners, regulatory bodies, and researchers.","PeriodicalId":292161,"journal":{"name":"Journal of Economics and Technology Research","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115410637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research method was applied descriptive which was conducted by field method using questionnaire. The statistical population included the athletes of sports clubs in Karaj city. The sample size was determined as 332 people based on Morgan’s table. The measurement tools included advertisement questionnaire (Moghimi & Ramezani, 2007) and customer attraction questionnaire (Ravanbakhsh, 2019). Content and face validity of questionnaires were confirmed by management professors and Cronbach’s alpha reliability was reported as 0.72 for advertisement questionnaire and Cronbach’s alpha reliability of customer attraction questionnaire was reported as 0.71. To analyze the research hypotheses, the structural equation model was used by spss19 and Amos23 software. The findings of the research showed that charitable marketing has a mediating role in the effect of advertising on the attraction of customers of sports clubs in Karaj city, and this type of mediating is a partial mediating type. Therefore, it can be concluded that by using charitable marketing, new customers can be attracted to sports clubs, and charitable marketing is also a kind of advertisement for the club.","PeriodicalId":292161,"journal":{"name":"Journal of Economics and Technology Research","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129640544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
