The purpose of this article is to reconsider the interaction between major oil and gas companies and the state, which is especially important for modern Russia given its current conditions. General theoretical approaches are presented, as well as calculations of price and financial indicators reflecting the performance of these companies. 相似文献

Financial and economic cost‐benefit models were applied to determine the worth of several planned community‐based, wildlife utilisation initiatives in Botswana, and to identify policy guidelines. Projects planned to incorporate small‐scale wildlife cropping. Rentals from safari‐hunting or wildlife‐viewing activities were found to have inherent viability, both financially and economically, particularly in the north of the country, where tourism is greatest. However, success is dependent on both good management and high densities of wildlife. In the Kalahari, game at low densities (more than 100 hectares per large stock unit) cannot be cropped profitably by communities and investments in game protection will result in economic gain. At higher game densities (between 100 and about 25 hectares per large stock unit), positive financial returns are possible with community‐based cropping but two considerations are important. First, investment in protection continues to pay economically and, second, cropping at close to maximum sustainable intensity is most profitable economically. Selective protection aimed at restoring proportions of drought‐sensitive game species also appears economically rewarding. 相似文献

The purpose of this study was to explore the relationship between online reviews and ratings through text mining and empirical techniques. An Indian food delivery portal ( Zomato.com ) was used, where 50 restaurants on Presence Across Nation (PAN) basis were selected through stratified random sampling. A total of 2530 reviews were collected, scrutinized, and analysed. Using the NVivo software for qualitative analysis, seven themes were identified from collected reviews, out of which, the ‘delivery’ theme was explored further for identifying sub-themes. Linear regression modelling was used to identify the variables affecting delivery ratings and sentiment analysis was also performed on the identified sub-themes. Regression results revealed that hygiene and pricing (delivery subthemes) demonstrated lower delivery ratings. These variables can be established as indicators for restaurants and related online food delivery services to build their business model around them. Similarly, negative sentiments were observed in pricing and hygiene sub-themes. Restaurants and online food services can enhance hygiene levels of their food delivery process in order to receive higher delivery ratings. Similarly, pricing of food items can be modified such that customers are not deterred from ordering the items—food and ordering service do not become cost-prohibitive. This study devised a standardized methodology for analysing vast amounts of online user-generated content (UGC). Findings from this study can be extrapolated to other sectors and service industries such as, tourism, cleaning, transportation, hospitals and engineering especially during the pandemic. 相似文献

The paper describes the current situation in the salt industry. It points to the inadmissibly high and expanding market share of imported salt products despite the country’s own colossal resource base and the domestic enterprises’ huge unused capacities. It has been shown that OAO Russian Railroads (OAO RZhD) will economically benefit due to its reasonable policy of selective reduction of the railroad shipment tariffs for salt for domestic producers due to the inevitable growth of the country’s own salt output. 相似文献

The Index of Consumer Expectations (ICE), which includes expenditures on durable goods, has been adopted as a leading indicator of national economic activity. A rational expectations model of the ICE was developed and the economic determinants of consumers' expectations were estimated. Aggregate expenditures on durable goods were explained by an endogenous ICE and sentiment about current economic conditions. Consumers were more likely to purchase durable goods when they felt better off in the current period relative to the future. 相似文献

This study of a sample of home gardeners indicates that rules of thumb, or heuristics, are used to select between chemical pesticides and nonchemical alternatives. Such rules of thumb serve to simplify otherwise complicated choice decisions. Heuristics commonly used to choose pesticides include how safe, effective, efficacious, and economical they are, whereas for alternative products consumers more often take into account convenience, efficiency, competency, and handiness. Generally, in an overall ranking of 24 individual choice attributes, pesticies rank low on these attributes where alternatives rank high and vice versa. Gender, age, and years using pesticides are significantly correlated with pesticide selection. 相似文献

State attorneys general recently proposed mandatory disclosures for rental car advertising. This study investigates the effects of alternate disclosure statements on consumers' beliefs. The results suggest that a shorter disclosure statement may be as effective as the one proposed. 相似文献
