Several Russian and foreign forecasts of energy industry development have been analyzed that were made in various years for up to 20–25 years. The extent and type of temporal variations in uncertainty ranges of forecast indexes in Russia and worldwide have been studied. The indexes include fluctuations of energy commodity prices, electricity and fuel production and consumption, etc. The calculated data have been given. The relations of uncertainty ranges of different indexes to the change in the considered timeframe have been constructed. 相似文献

It has been shown how static and dynamic characteristics could be used for a comparative assessment of social, environmental, and economic development, as well as the development balance in social, economic, and ecological spheres. The proposed methodological toolkit has made it possible to identify problem areas and stably manifested dynamic disproportions in the investigated regions, which require corrective actions in order to ensure sustainable development. 相似文献

This paper estimated the relationship between employment and depression, hypertension, diabetes and tuberculosis in South Africa between 2008 and 2014. South Africa has high levels of economic inactivity and unemployment as well as a high disease burden occasioned by depression, other non-communicable diseases and tuberculosis. Data came from the National Income Dynamics Study panel dataset. Using fixed effects, random effects and pooled ordinary least squares regressions, depression and diabetes were associated with a 4–6 percentage point decline in employment probability, while tuberculosis was associated with a 12–13 percentage point employment decline. The results suggested that the employment-health relationship possibly operated through illness being associated with increased economic inactivity, rather than through making the search efforts of the unemployed unsuccessful. Moreover, the employment-health relationship not only existed contemporaneously, but extended into the future (especially for the physical health indicators). 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

While bank liabilities in Sub-Saharan Africa are found to follow (but not lead) economic growth, the link between bank credit and growth is altogether absent. 相似文献

Ventilator-associated pneumonia (VAP) accounts for the majority of nosocomial pneumonias, which may increase intensive care and prolonged hospital stays. Endotracheal tubes allowing continuous subglottic suctioning may reduce VAP; however, they are more expensive than standard endotracheal tubes not allowing continuous suctioning. he objective of this study was to measure the comparative costs associated with continuous subglottic suctioning endotracheal tubes (CSS-ETT) versus standard endotracheal tubes (S-ETT) among intubated patients and whether cost differential is offset by the occurrence of VAP in patients receiving either type of intubation. A retrospective chart review was conducted for 154 intubated adult patients (77 = S-ETT; 77 = CSS-ETT). The S-ETT group had one case of VAP; the CSS-ETT group had none. The mean total hospital charges were higher for the S-ETT group ($103,600; CSS-ETT= $88,500) (p = 0.3). Although the average number of intubation days and ICU days were greater for the CSS-ETT group, there were no cases of VAP compared to the S-ETT group. ased upon the one S-ETT VAP case and the VAP attributable costs, it is cost effective to use the CSS-ETT. 相似文献

At the European level there is an increasing focus on how freight transport can be moved from trucks on roads to more environmentally friendly modes such as rail and ship. A large proportion of the transport services between OD pairs, however, cannot be substituted since there is only one alternative available. The paper investigates the magnitude of this “structural inelasticity” of modal substitution in freight transport due to a sparser layout of rail and ship-based freight networks compared to road. In the analysis we use a recent Scandinavian freight demand model covering more than 800 zones. We find that the structural inelasticity is very significant - in particular for transportation over less than 500 km. Moreover, the inelasticity varies greatly with commodity groups and between OD pairs, and it depends strongly on the port and rail infrastructure. The results suggest that pure charging instruments (road pricing for trucks) in many regions will have limited mode substitution impacts. However, if combined with structural changes in terms of improved infrastructure for rail and ship, impacts may be greater. 相似文献

ABSTRACTThis study investigates job location and its relationship with employee turnover intention within the casino-entertainment industry. The researchers analyzed turnover intention at the supervisor and company level from the perspective of employees who hold front-of-house or back-of-house jobs in three Nevada casinos and their corporate office. The results of this research fill existing gaps in the academic literature related to turnover intention and provide beneficial implications for industry and academic practitioners. Organizations within the casino-entertainment industry may develop strategies related to the management of human capital that could provide fiscal and operational benefits. 相似文献

This paper estimates the magnitude of the Balassa-Samuelson effect for Greece. We calculate the effect directly, using sectoral
national accounts data, which permits estimation of total factor productivity (TFP) growth in the tradeables and nontradeables
sectors. Our results suggest that it is difficult to produce one estimate of the BS effect. Any particular estimate is contingent
on the definition of the tradeables sector and the assumptions made about labour shares. Moreover, there is also evidence
that the effect has been declining through time as Greek standards of living have caught up on those in the rest of the world
and as the non-tradeables sector within Greece catches up with the tradeables.
