APPLICATIONS OF SOCIAL CAPITAL THEORY

Experiments and studies were conducted to investigate the role of social capital. Social capital (relationship to others) is a productive asset which is a substitute for and complement to other productive assets. The productivity of social capital leads to the expectation that firms and individuals invest in relationships. Data were collected to answer the following questions: Does the identity (relationship) of trading partners affect selling and buying prices; the acceptance of catastrophic risk; the choice of share or cash leases in agriculture; loan approval; and the banks investment to retain customers? The evidence is in the affirmative.Behavioral economics, Institutional economics, Social capital, Institutional and Behavioral Economics,

Digital accumulator relies almost entirely on integrated circuitry to process the data derived from the outputs of gyro shaft encoder. After the read command is given, the output register collects and stores the data that are on the set output terminals of the up-down counters

The Role of Social Capital in the Industrialization of the Food System

Selfishness of preferences alone will not support the coordination necessary for the industrialization of the food system. Social capital relationships of mutual sympathy (caring) yield socio-emotional goods that are important in the more personal business world of evolving incomplete contracts and alliances involving input suppliers, processors, and labor. Relationships are also critical when consumers are buying image as well as physical products. Management and policy alternatives constitute investment in social capital that can affect opportunism, risk, loyalty, and trust.Agricultural Finance,

IS SOCIAL CAPITAL REALLY CAPITAL?

Social capital in the past two decades has emerged as a dominant paradigm in the various social science disciplines. However, its adoption by the different social science disciplines has led to multiple and often conflicting definitions of social capital. Some differences in the definition of social capital can be explained because scientists have included in the definition expressions of its possible uses, where it resides, and how its service capacity can be changed. This paper defends the social capital metaphor by pointing out that social capital has many important capital-like properties including service potential, durability, flexibility, substitutability, opportunities for decay (maintenance), reliability, ability to create other capital forms, and investment (disinvestment) opportunities. Social capital is compared to other forms of capital including cultural capital and human capital.

SOCIAL CAPITAL AND POVERTY REDUCTION: TOWARD A MATURE PARADIGM

Introduction The purposes of this paper are: (1) to introduce the social capital paradigm; (2) to present evidence that social capital has an important role in poverty reduction; and (3) to suggest several policy prescriptions for building and using social capital to reduce poverty. The social capital paradigm includes social capital, networks, socio-emotional goods, attachment values, institutions, and power. Social capital is a person or group's sympathy for others. Social capital resides in sympathetic relationships that can be described using networks. One reason to value social capital is because it can produce economic benefits and if neglected, economic disadvantages. Another reason to value social capital is because it can be used to produce socio-emotional goods. Sometimes socio-emotional goods become embedded in objects. When this occurs, the meaning and value of the object change. The change in the value of an object produced by embedded socio-emotional goods is the object's attachment value. Individuals exchange both physical and socio-emotional goods. Institutions are the rules that order and give meaning to exchanges. Institutions with high attachment values are more likely to be observed than those whose compliance depends on economic incentives or threats. Finally, power, the ability to influence others, depends on one's resources, including one's social capital. In most personalized transactions, persons exchange both socio-emotional goods and physical goods and services. Moreover, the relative amounts of socio-emotional goods and physical goods and services exchanged will alter the levels and terms of trade when measured in physical units. Since one's ability to include socio-emotional goods in exchanges for physical goods and services depends on one's social capital, the terms and levels of exchange of physical goods and services will be influenced by the transacting party's social capital. Those with high levels of social capital will have advantages over those who lack social capital because they can exchange both socio-emotional goods and physical goods and services. Furthermore, since social capital alters the terms and levels of trade and the terms and levels of trade influence the distribution of incomes derived from trades, then social capital also has an important influence on the distribution of household income and poverty. Some evidence suggests that the distribution of social capital in networks and the distribution of household incomes are connected.Food Security and Poverty, Institutional and Behavioral Economics,

Synthesis and analysis of jet fuel from shale oil and coal syncrudes

Thirty-two jet fuel samples of varying properties were produced from shale oil and coal syncrudes, and analyzed to assess their suitability for use. TOSCO II shale oil and H-COAL and COED syncrudes were used as starting materials. The processes used were among those commonly in use in petroleum processing-distillation, hydrogenation and catalytic hydrocracking. The processing conditions required to meet two levels of specifications regarding aromatic, hydrogen, sulfur and nitrogen contents at two yield levels were determined and found to be more demanding than normally required in petroleum processing. Analysis of the samples produced indicated that if the more stringent specifications of 13.5% hydrogen (min.) and 0.02% nitrogen (max.) were met, products similar in properties to conventional jet fuels were obtained. In general, shale oil was easier to process (catalyst deactivation was seen when processing coal syncrudes), consumed less hydrogen and yielded superior products. Based on these considerations, shale oil appears to be preferred to coal as a petroleum substitute for jet fuel production

Distinguishing wet from dry age-related macular degeneration using three-dimensional computer-automated threshold Amsler grid testing

Background/aims: With the increased efficacy of current therapy for wet age-related macular degeneration (AMD), better ways to detect wet AMD are needed. This study was designed to test the ability of three-dimensional contrast threshold Amsler grid (3D-CTAG) testing to distinguish wet AMD from dry AMD. Methods: Conventional paper Amsler grid and 3D-CTAG tests were performed in 90 eyes: 63 with AMD (34 dry, 29 wet) and 27 controls. Qualitative comparisons were based upon the three-dimensional shapes of central visual field (VF) defects. Quantitative analyses considered the number and volume of the three-dimensional defects. Results: 25/34 (74%) dry AMD and 6/29 (21%) wet AMD eyes had no distortions on paper Amsler grid. Of these, 5/25 (20%) dry and 6/6 (100%) wet (p=0.03) AMD eyes exhibited central VF defects with 3D-CTAG. Wet AMD displayed stepped defects in 16/28 (57%) eyes, compared with only 2/34 (6%) of dry AMD eyes (p=0.002). All three volumetric indices of VF defects were two- to four-fold greater in wet than dry AMD (p<0.006). 3D-CTAG had 83.9% positive and 90.6% negative predictive values for wet AMD. Conclusions: 3D-CTAG has a higher likelihood of detecting central VF defects than conventional Amsler grid, especially in wet AMD. Wet AMD can be distinguished from dry AMD by qualitative and quantitative 3D-CTAG criteria. Thus, 3D-CTAG may be useful in screening for wet AMD, quantitating disease severity, and providing a quantitative outcome measure of therapy
