ACCESS TO CAPITAL AND FIRM-LEVEL INVESTMENT BEHAVIOR IN FOOD INDUSTRIES: A COMPARISON OF COOPERATIVES AND PUBLICLY TRADED FIRMS

This paper compares investment behavior of agricultural cooperatives and publicly traded firms in the food industry. The importance of financial constraints is examined by exploring whether ownership structure affects investment sensitivity to cash flow using a panel data approach based on the Q-theory of investment.Agribusiness,

TESTING FOR THE PRESENCE OF FINANCIAL CONSTRAINTS IN U.S.

It is commonly argued in the literature that agricultural cooperatives are financially constrained because they are unable to acquire sufficient risk capital to invest in productive assets. This study examines whether agricultural cooperatives' investment is constrained by estimating neoclassical and cash flow augmented Q investment models. Panel data regression results suggest that cooperative physical capital investment responds positively and significantly to both the marginal profitability of capital and cash flow. Results also indicate that all cooperative sub-samples face binding financial constraints when making investment decisions, but some cooperatives appear to be less financially constrained than others. The empirical analysis of the cooperative financial constraint hypothesis suggests that eliminating restrictions on residual claims might be a necessary condition for the attenuation of capital constraints in agricultural cooperatives.Agribusiness,

Strategic Alliances in the U.S. Beef Supply Chain

This study analyzes vertical-coordination practices in the U.S. beef supply chain focusing on strategic alliances. We present results from a survey of beef alliances describing their organizational structure, the nature of participantsÂ’' involvement, contractual requirements, information-sharing practices, services offered to alliance participants, and marketing strategies. Survey results provide a detailed description of 13 beef alliances and are intended to inform potential participants about vertical-coordination alternatives. In addition, the study provides relevant information for future economic research on the formation, organization, and functioning of beef alliances.Livestock Production/Industries, Marketing,

Multi texture analysis of colorectal cancer continuum using multispectral imagery

Purpose This paper proposes to characterize the continuum of colorectal cancer (CRC) using multiple texture features extracted from multispectral optical microscopy images. Three types of pathological tissues (PT) are considered: benign hyperplasia, intraepithelial neoplasia and carcinoma. Materials and Methods In the proposed approach, the region of interest containing PT is first extracted from multispectral images using active contour segmentation. This region is then encoded using texture features based on the Laplacian-of-Gaussian (LoG) filter, discrete wavelets (DW) and gray level co-occurrence matrices (GLCM). To assess the significance of textural differences between PT types, a statistical analysis based on the Kruskal-Wallis test is performed. The usefulness of texture features is then evaluated quantitatively in terms of their ability to predict PT types using various classifier models. Results Preliminary results show significant texture differences between PT types, for all texture features (p-value < 0.01). Individually, GLCM texture features outperform LoG and DW features in terms of PT type prediction. However, a higher performance can be achieved by combining all texture features, resulting in a mean classification accuracy of 98.92%, sensitivity of 98.12%, and specificity of 99.67%. Conclusions These results demonstrate the efficiency and effectiveness of combining multiple texture features for characterizing the continuum of CRC and discriminating between pathological tissues in multispectral images

The Emergence of Non-Traditional Cooperative Structures: Public and Private Policy Issues

This paper examines new agricultural cooperative organizational models from an ownership rights perspective. We argue that new cooperative organizational models differ in the way ownership rights are assigned to the economic agents tied contractually to the firm � members, patrons, and investors. The paper proposes a typology of discrete organizational models, in which the traditional cooperative structure and the investor-oriented firm are characterized as polar forms. Five non-traditional models are described and analyzed with implications to both private and public policy.agricultural cooperatives, cooperative finance, ownership structure, property rights., Agribusiness,
