Recently, a computer-aided interactive design system has been used for turbine design. The blade-to-blade flow program incorporated in the system is required to have short run times, robustness, and no limitations. The Denton time-marching code is attractive as it is fast and can handle mixed subsonic–supersonic flows. The Denton new scheme was published in 1982 and improvements were achieved in run times and entropy conservation. In this paper, code control variables are calibrated from the user’s point of view. Factors affecting computing costs and accuracy are investigated, and the “know-how” necessary to operate the code efficiently is discussed. Comparisons of calculated and experimental results are presented in part II.

Turbine Design

A blade-to-blade flow program incorporated in the computer-aided turbine design system is required to have short run times, robustness, and no limitations. The Denton time-marching method published in 1982 is attractive as it is fast and can handle mixed subsonic-supersonic flows. Calibration of code control variables is discussed in part I. In this paper, the scheme is extensively verified by comparing calculated surface Mach number distributions with experimental data obtained from two-dimensional cascade tests for 23 cascades. For the nozzles, excellent agreement is obtained if the flows are fully subsonic, or transonic with weak shock–boundary layer interaction. For the blades, very good agreement is also obtained if the blades have moderate blade reaction and viscous effects are small. Satisfactory results are obtained for suction surface diffusion, even at off-design inlet conditions, if absolute values of incidence angle are less than 10 deg.

AbstractIntegrated economic models have become popular for assessing climate change. In this paper we show how these methods can be used to assess the impact of a discard ban in a fishery. We state that a discard ban can be understood as a confiscatory tax equivalent to a value-added tax. Under this framework, we show that a discard ban improves the sustainability of the fishery in the short run and increases economic welfare in the long run. In particular, we show that consumption, capital and wages show an initial decrease just after the implementation of the discard ban then recover after some periods to reach their steady-sate values, which are 16–20% higher than the initial values, depending on the valuation of the landed discards. The discard ban also improves biological variables, increasing landings by 14% and reducing discards by 29% on the initial figures. These patterns highlight the two channels through which discard bans affect a fishery: the tax channel, which shows that the confiscation of landed discards reduces the incentive to invest in the fishery; and the productivity channel, which increases the abundance of the stock. Thus, during the first few years after the implementation of a discard ban, the negative effect from the tax channel dominates the positive effect from the productivity channel, because the stock needs time to recover. Once stock abundance improves, the productivity channel dominates the tax channel and the economic variables rise above their initial levels. Our results also show that a landed discards valorisation policy is optimal from the social welfare point of view provided that incentives to increase discards are not created.

PurposeThis study aims to identify the efficiency scores of hospitals affiliated to the Ministry of Health in Turkey between the years of 2010–2015 at provincial level and to reveal the factors that affect the efficiency scores.Design/methodology/approachThe two-stage data envelopment analysis (DEA) method was used to achieve the study purpose. In the first stage, DEA method based on input-oriented Charnes–Cooper–Rhodes (CCR) model was performed to calculate the efficiency scores of public hospitals at the provincial level between 2010 and 2015, and in the second stage, Tobit regression and linear regression analyses were used to identify whether the efficiency scores of provinces are affected by the input, output and control variables.FindingsUpon the analysis, the average efficiency scores of 81 provinces by years were found to vary between 0.79 and 0.89. According to both regression analyses, all of the input and output variables were found to have significant effects on the efficiency scores of provinces while only the population of province among the control variables was identified as the factor with an effect on the efficiency scores of provinces (p < 0.05).Practical implicationsThe results of this study are thought to guide health policymakers and managers in terms of both determining efficient and inefficient hospitals at the provincial level and revealing which variables should be taken into account in order to increase efficiency.Originality/valueThe study differs from previous studies on the efficiency of hospitals. First, although previous studies were generally descriptive studies to determine the efficiency level of hospitals, this study is an analytical study that tries also to show the factors affecting the efficiency of hospitals. In addition, while examining the effect of input and output variables on efficiency scores, control variables were also included in the study.

Lentil is an important pulse crop widely grown in Bangladesh. It ranks first among the pulses in terms of area and consumers’ preference. BARI has developed many improved lentil varieties and disseminated to the farmers fields. The up-to-date information regarding adoption and financial profitability of this crop are unknown to the researchers and policymakers. Therefore, the study was conducted in Jhenaidah and Jessore districts to determine the adoption status and profitability of BARI lentil production and to examine the factors affecting the yield of BARI lentil during 2010-2011. Cobb-Douglas production function was used. The study revealed that 98% of the total lentil cultivated areas were occupied by BARI lentil varieties in the study areas. The average level of adoption of BARI Masur-3, BARI Masur-4, BARI Masur-5 and BARI Masur-6 were 49%, 47%, 1% and 1%, respectively at farm level. The cultivation of BARI lentil was profitable to the farmers since the per hectare total cost, gross return and net return of BARI lentil cultivation were Tk 52,734, Tk 80,572 and Tk 27,838, respectively. Functional analysis revealed that seed, urea, mechanical power cost and pesticides had positive effect on the yield of lentil production. Unavailability of latest BARI lentil seed, lack of technical know-how, lack of training, and diseases (root rot and stemphylium blight) were the main constraints to BARI lentil cultivation at farm level. BARI Masur-3 and BARI Masur-4 were the highly adopted varieties. The lentil production was profitable to the farmers in the study areas DOI: http://dx.doi.org/10.3329/bjar.v37i4.14384 Bangladesh J.

Contemporary Standard

For the linguistic expression of the concept of knowledge, the Slavic languages use verbs deriving from the Indo-European roots *ĝnō and *ṷei̭d. They differ in terms of the availability of both types of verbs in the contemporary standard languages and in terms of their semantic range. As will be shown in this paper, these differences are interesting not only from a language-specific lexicological point of view, but also in the context of the intersection of lexicon and grammar. Covering the domain of ‘knowing how,’ the *ĝnō-based verb in Slovene (znati) has been extending into the domain of possibility and, on this basis, developing into a modal verb. While this development is not surprising from a typological point of view, it is remarkable from a Slavic perspective, since this particular grammaticalisation path towards possibility is otherwise unknown to Slavic. This peculiar feature of Slovene, which most probably relates to its long-lasting and intensive contact with German, is illustrated in the present paper by comparing Slovene to Russian on the basis of three main questions: 1) the semantic range of vedeti / vedatʹ and znati / znatʹ, 2) the lexicalisation of ‘know how,’ and 3) the relation between knowledge, ability, and possibility. The focus is on contemporary Slovene and Russian, leaving a detailed diachronic investigation and the further embedding into a larger Slavic and areal perspective for future analyses.
