Presenting Modified Servqual Model to Evaluate Flight Attendant Services: Iran Air case study

Purpose: The investigation of the customer`s viewpoints and utilizing their ideas and expectations in improving the quality of the products, has turned out to be one of the key concerns of the companies working in all fields. Airline industry as one of the most extensive modes of transportation should be strictly accurate in providing services to their customers. This article attempts to investigate important dimensions from passengers' point of view and present a model which would evaluate the flight attendant's performance. Design/methodology: In order to achieve this purpose, on the basis of the literature and experts' and passengers' point of view, the SERVQUAL model has been modified with 26 factors in 6 dimensions. Then 300 data have been gathered for the Factor Analysis Model. Findings: As a result, a model with high goodness of fit has been developed which could be used as a tool of measuring quality of service with a high degree of certainty. In the end, running the model in Iran air, most differences were as below: 1-Improvement 2-Responsiveness 3-Empathy 4-Assurance 5-Tangibles 6-Reliability. Originality/value: In general, in this model, all services with which employees are involved are observed. However, the main issue in this research is related to attendant team. Consequently, considering that many of these indicators have different meanings in assessing customer satisfaction in relation to the performance of flight attendant; modifications should be made to the dimensions of the SERVQUAL model.Peer Reviewe

ANALYZING REPRODUCTIVE MANAGEMENT STRATEGIES ON DAIRY FARMS

Milk sales are the largest source of revenue on dairy farms. Reproduction is necessary to generate a new lactation. However, a pregnancy also dictates when the previous lactation must end so that the cow can retain sufficient condition into her new lactation. Pregnancy rate and estrus detection rate determine reproductive success. From an economics point of view, we talk about calving interval or days open so that a dollar value can be easily associated with the reproductive management program.Livestock Production/Industries,

THE IMPACT OF HACCP ON FACTOR DEMAND AND OUTPUT SUPPLY ELASTICITIES OF RED MEAT

This study uses firm-level data during the hazard analysis critical control point (HACCP) implementation period (1997 - 2000) to analyze the impact of HACCP on input demand and output supply elasticities of firms in the red meat industry and derive implications for efficiency and moral hazard issues associated with the implementation of HACCP systems. The results show that HACCP causes factor demand for labor, material, and capital to be less inelastic while the elasticity of output supply did not change significantly. The interdependent relationships among HACCP and input prices and output result in efficiency gains.HACCP, factor demand, elasticities of substitution, output supply elasticities, translog cost function, efficiency, red meat, Food Consumption/Nutrition/Food Safety,

Organic Food Consumption Patterns in France

This research addresses two important issues for the future expansion of organic consumption in France. The first one is related to knowing whether the organic choice is a permanent feature of consumer’s attitude or not: Do organic buyers occasionally pick one organic product or do they choose organic for “several” categories? The second issue concerns the impact of prices on buying organics which is revisited, distinguishing between capturing new consumers and increasing the demand coming from people already involved in organic markets. These questions are examined using the market basket approach; the price issue requires further estimations of demand models. The study relies on two staple food products, eggs and milk. The findings are : (i) choosing organic for one of the two items reinforces the probability of purchasing also the organic version of the second item; (ii) marginal reductions of the organic price have no impact on the decision of buying organic rather than conventional products; (iii) on the contrary, when people already purchase organic products, price elasticities are rather high; (iv) organic buyers’ demographic profile is not related to income neither to age nor to family size, but to the educational level.market basket approach, purchasing behavior, logit model, Consumer/Household Economics, Demand and Price Analysis, Food Consumption/Nutrition/Food Safety, C35, D12, Q13,

Cost analysis for the reconstruction of apartment based upon standard and luxury design

Tato bakalářská práce se zabývá standardním a nadstandardním provedením rekonstrukce půdních prostor na byt a jejím následným oceněním dle Oceňovací vyhlášky. V teoretické části je zaměřena na problematiku cen a nákladů a vysvětluje některé základní pojmy této problematiky. V praktické části je uveden způsob a výsledné ceny sestavených rozpočtů a následné ocenění bytu v obou provedeních.This bachelor thesis deals with both standard and luxury design versions of reconstruction of the attic to flat and its subsequent valuation based on the Ordinance of valuation. The teoretical part is focused on the subject of prices and expenses. It also explains some of the basic terms of this domain. The practical part deals with methods of compiling budgets and their final prices with ensuing valuation of the appartment in both forms.

Microeconomics of nitrogen fertilization in boreal carbon forestry

Nitrogen fertilization of boreal forests is investigated in terms of microeconomics, as a tool for carbon sequestration. The effects of nitrogen fertilization's timing on the return rate on capital and the expected value of the timber stock are investigated within a set of semi-fertile, spruce-dominated boreal stands, using an inventory-based growth model. Early fertilization tends to shorten rotations, reducing timber stock and carbon storage. The same applies to fertilization after the second thinning. Fertilization applied ten years before stand maturity is profitable and increases the timber stock, but the latter effect is small. Fertilization of mature stands, extending any rotation by ten years, effectively increases the carbon stock. Profitability varies but is increased by fertilization, instead of merely extending the rotation.Comment: 16 pages, 9 Figure

Consequences of climate change on food-energy-water systems in arid regions without agricultural adaptation, analyzed using FEWCalc and DSSAT

Effects of a changing climate on agricultural system productivity are poorly understood, and likely to be met with as yet undefined agricultural adaptations by farmers and associated business and governmental entities. The continued vitality of agricultural systems depends on economic conditions that support farmers’ livelihoods. Exploring the long-term effects of adaptations requires modeling agricultural and economic conditions to engage stakeholders upon whom the burden of any adaptation will rest. Here, we use a new freeware model FEWCalc (Food-Energy-Water Calculator) to project farm incomes based on climate, crop selection, irrigation practices, water availability, and economic adaptation of adding renewable energy production. Thus, FEWCalc addresses United Nations Global Sustainability Goals No Hunger and Affordable and Clean Energy. Here, future climate scenario impacts on crop production and farm incomes are simulated when current agricultural practices continue so that no agricultural adaptations are enabled. The model Decision Support System for Agrotechnology Transfer (DSSAT) with added arid-region dynamics is used to simulate agricultural dynamics. Demonstrations at a site in the midwest USA with 2008–2017 historical data and two 2018–2098 RCP climate scenarios provide an initial quantification of increased agricultural challenges under climate change, such as reduced crop yields and increased financial losses. Results show how this finding is largely driven by increasing temperatures and changed distribution of precipitation throughout the year. Without effective technological advances and operational and policy changes, the simulations show how rural areas could increasingly depend economically on local renewable energy, while agricultural production from arid regions declines by 50% or more
