A munkahelyi étkezés hazai fogyasztói piacának vizsgálata AgEcon
Fodor, Monika; Gyenge, Balazs; Horvath, Agnes.
Tanulmányunkban 1000 fős országos felmérés eredményei alapján azonosítottuk a hazai munkahelyi étkezés fogyasztói szegmenseit. Bebizonyítottuk, hogy a célcsoportok szocio-demográfiai ismérvek mellett az étkezési és élelmezési szokások, a munkahelyi étkezéshez való viszony szerint is eltéréseket mutatnak, amely igazolja, hogy ezen ismérvek befolyásolják az egyént abban, hogy milyen munkahelyi étkezési formát választ. Megállapítható, hogy a munkahelyi étkezés igénybevétele leginkább az időtudatos élelmiszer-fogyasztói magatartással függ össze, de megjelennek a kényelem, a termékminőség és a kiegészítő szolgáltatások iránti fogyasztói elvárások is. Az eredmények segítséget jelenthetnek a piacfejlesztési, piacbővítési lehetőségek definiálásában és a célpiaci...

A performance measure to support decision-making in Agricultural Research Center in Brazil. Repositório Alice
SOUZA, G. da S. e; GOMES, E. G..
The assessment of productive efficiency of a public research institution is of fundamental importance for its administration. A better management of available resources may be accompliched if managers have at their disposal meaningful quantitative measurements of the production process. In this paper we use Multivariate Analysis an Data Envelopment Analysis to define a performance measure for the research centers of the Brazilian Agricultural Research Corporation. Multiple production indicators are reduced to three output variables by means of maximum likelihood factor analysis. Performance is determined on the basis of this output vector and a three dimensional input vector defined by cost components. We impose restrictions on the optimization algorithm...

A STUDY OF THE IMPACT OF LAND USE AND OCCUPATION ON BASIN WATER QUALITY THROUGH MULTIVARIATE STATISTICS REA
Santos,Gilmar O.; Hernandez,Fernando B. T.; Ferraudo,Antonio S.; Vanzela,Luiz S.; Santos,Duílio J. O..
ABSTRACT Without effective actions to improve environmental management, water resources tend to become scarce. Thus, this study aimed to understand the processes influencing the physical, chemical, and biological properties of the water due to land uses and occupation in the Ipê stream basin, in Ilha Solteira - SP (Brazil), regarding the dependence of the analyzed variables. Monitoring of chemical, physical, and biological water quality was performed from 2006 to 2011, and the records of land use and occupation in 2011. A factorial multivariate analysis allowed us to understand that the processes in densely populated areas increased degradation of water by the input of organic loads, yet those of farming areas enhanced the degradation of the chemical and...

A Typology of Food Security in Developing Countries under High Food Prices AgEcon
Yu, Bingxin; You, Liangzhi; Fan, Shenggen.
The recent surge in food prices around the world may reverse the gains of reducing hunger and poverty in the recent years. This paper employs factor and sequential typology analysis using data for 175 countries to identify groups of countries categorized according to four measures of food security: utilization, availability, accessibility and stability. Nine indicators are used for this study: calories intake, protein intake, fat intake, food production, the ratio of total exports to food imports, soil fertility, length of growing period, coefficient of variation of length of growing period and urbanization. The analysis first identifies 5 distinct food security groups characterized by food intake then further split these groups based on similarities and...

ADOPTION OF E-COMMERCE STRATEGIES FOR AGRIBUSINESS FIRMS AgEcon
Henderson, Jason R.; Dooley, Frank J.; Akridge, Jay T..
This paper analyzes the factors guiding Internet and e-commerce implementation by agribusiness firms. The relationship between Internet/e-commerce strategies and manager perceptions on the barriers and factors to e-commerce adoption are analyzed in a supply-chain management framework. Using factor analysis and an ordered Probit model, results indicate that the implementation of Internet/e-commerce strategies is more likely to be adopted in larger firms with a global scope. Also, manager perceptions regarding supply-chain functions influencing transaction costs are more strongly associated with Internet/e-commerce adoption than other functions influencing production costs.

Agriculture and Protection of Landscape Area of the White Carpathians AgEcon
Krumalova, Veronika; Backman, Stefan.
The protected landscape area of the White Carpathians in Czech Republic is confronted with several threats. The protection of the landscape involves instituted policies and restrictions on production. Due to the approaching EU accession and the possible subsequent institutional changes, there is an increased demand for knowledge on production opportunities and threats. In addition there are immediate concerns on the relation between agricultural production and the environment. One major concern is the abandonment of agricultural land. In this article the combination of production elements and protection is described. Factor analyses are used to identify groups of farms with similarities in production structure and organisation. The results of the factor...

ANALYZING AGRICULTURE PRODUCTIVITY INDICATORS AND IMPACT OF CLIMATE CHANGE ON CEECS AGRICULTURE AgEcon
Singh, Mahesh Kumar; Kapuszta, Agnes; Fekete-Farkas, Maria.
The agriculture has an outstanding importance both in social and economic point of view, especially in the countries where the agriculture plays a vital role in economy. This paper mainly focuses on the situation in the Central and Eastern European countries (CEECs). The share of agriculture in CEECs is more significant both in GDP and employment than in the old member states of EU. To be competitive on the single market, we have to know the advantages and disadvantages, strength and weakness of different sectors of agriculture. Traditionally, in these countries to measure the effectiveness, the partial factor analyses are used. To get more accurate overview, we need to use more wide technique to sampling measurement. This paper summarizes the measurement...

Biased estimates in discrete choice models: the appropriate inclusion of psychometric data into the valuation of recycled wastewater AgEcon
Gibson, Fiona L.; Burton, Michael P..
The introduction of measurement bias in parameter estimates into non-linear discrete choice models, as a result of using factor analysis, was identified by Train et al. (1987). They found that the inclusion of factor scores, used to represent relationships amongst like variables, into a subsequent discrete choice models introduced measurement bias as the measurement error associated with each factor score is excluded. This is an issue for non-market valuation given the increase in popularity of including psychometric data, such as primitive beliefs, attitudes and motivations, in willingness to pay estimates. This study explores the relationship between willingness to pay and primitive beliefs through a case study eliciting Perth community values for...

Zimpel,Roney; Bánkuti,Ferenc Istvan; Zambom,Maximiliane Alavarse; Kuwahara,Kellen Cristina; Bánkuti,Sandra Mara Schiavi.
ABSTRACT The objective of this paper was to analyze financial management practices in dairy production systems. More specifically, we sought to identify which milk producers adopt financial management practices. We conducted 55 semi-structured questionnaires in the Western Region of Paraná. The data were processed through descriptive and multivariate statistical analysis. The analysis of hierarchical clusters defined, based on variables related to financial management practices, two distinct groups. The first group included milk producers who do not adopt financial management practices (N = 49) and the second group described the milk producers who do adopt these practices (N = 6). We then used Common Factor Analysis, along with structural, technical,...

Chinese Consumers' Preferences for Livestock Products AgEcon
Peng, Xuehua; Marchant, Mary A.; Qin, Xiang Dong; Zhuang, Jun.
This research surveyed over 784 Chinese consumers in Shanghai and Nanjing in 2001 and 2002, evaluating their preferences for livestock product attributes using ordered-probit models and factor analyses. Empirical results confirm the heterogeneity of Chinese livestock retail markets and suggest that livestock distributors should focus on Chinese female consumers and young consumers considering cooking convenience as a key attribute. Chinese consumers with higher incomes placed less importance on product price and shopping environment and more importance on product quality and brand name. Highly-educated Chinese consumers placed more importance on the brand name attribute. Our findings also indicate that it is crucial for U.S. livestock exporters to create...

Defining and Characterizing Approaches to Farm Management AgEcon
McBride, William D.; Johnson, James D..
Exploratory factor analysis was used to identify approaches to farm management based on a list of management questions posed to a sample of U.S. cash-grain farmers. Three approaches were identified by the factor analysis: price negotiation, long-term cost control, and input adjustment. Estimated factor scores regressed against farm and operator characteristics indicate a profile of producers using each approach that is closely related to stage-of-life of the farm operator and farm business. In addition to operator age and planning horizon, operator risk preference and farm organization and location were other important determinants of the approach to management.

Dimensionality of the premenstrual syndrome: confirmatory factor analysis of premenstrual dysphoric symptoms among college students BJMBR
Wang,Y.-P.; Teng,C.-T.; Vieira Filho,A.H.G.; Gorenstein,C.; Andrade,L.H..
Premenstrual syndrome and premenstrual dysphoric disorder (PMDD) seem to form a severity continuum with no clear-cut boundary. However, since the American Psychiatric Association proposed the research criteria for PMDD in 1994, there has been no agreement about the symptomatic constellation that constitutes this syndrome. The objective of the present study was to establish the core latent structure of PMDD symptoms in a non-clinical sample. Data concerning PMDD symptoms were obtained from 632 regularly menstruating college students (mean age 24.4 years, SD 5.9, range 17 to 49). For the first random half (N = 316), we performed principal component analysis (PCA) and for the remaining half (N = 316), we tested three theory-derived competing models of PMDD by...
