EXPERIENCES WITH FARMER ORIENTED LINEAR PROGRAMMING FOR CROP PLANNING

This paper presents a linear programming model for farm planning known as the "Purdue Top Farmer Cropping Model 'B'." This model is designed for direct use with farmers and has been used by more than 5,000 individuals. The paper describes the features of this model and discusses the rationale for these features. In this process details on application, evolution and impact of the model are given. The success of the model is due to its design and the interplay between research and extension personnel in the model design.

Price Reporting in Experimental Markets

The spatial oligopoly model has been proposed as a method of explaining behavior in food markets, particularly in response to retail food price reporting systems. This paper presents an analysis of the effects of price reporting in experimental spatial duopoly markets with controlled buyer behavior. The experiments are designed to evaluate the impact of a changed information flow on the price decisions of oligopolistic sellers. The short-run theoretical predictions of the spatial model are largely consistent with experimental market results. Thus, the spatial oligopoly model is not rejected as an explanation of seller response to changed price information Rows.
Le modéle oligopolistique spatial a déjà été proposé pour expliquer le comportement des marches alimentaires, tel que déterminé en particulier par les systémes d'inforrnation sur les prix au detail des aliments. Nous présentons une analyse des effets du systéme d'information sur les prix dans des marches duopolistiques spatiaux expérmentaux dans lesquels le comportement des acheteurs est contrôle. Ces expériences sont conpes pour évaluer I'incidence d'un changement dans la transmission des informations sur les décisions des vendeurs oligopolistiques concernant les prix. Les prévisions théoriques a court terme du modele spatial sont largement en accord avec les rksultats experimentaux. Ainsi, le modéle oligopolistique spatial peut he retenu pour expliquer la réaction des vendeurs è des chan-gements sumenus dans la transmission des informations sur les prix.     

META‐ANALYSIS OF ECONOMICS RESEARCH REPORTING GUIDELINES

Meta‐regression analysis (MRA) can provide objective and comprehensive summaries of economics research. Their use has grown rapidly over the last few decades. To improve transparency and to raise the quality of MRA, the meta‐analysis of economics research‐network (MAER‐Net) has created the below reporting guidelines. Future meta‐analyses in economics will be expected to follow these guidelines or give valid reasons why a meta‐analysis must deviate from them.     

The contribution of corporate social responsibility to organizational commitment

This study investigates the relationship between organizational commitment and employee perceptions of corporate social responsibility (CSR) within a model that draws on social identity theory. Specifically, we examine the impact of three aspects of socially responsible behaviour on organizational commitment: employee perceptions of corporate social responsibility in the community, procedural justice in the organization and the provision of employee training. The relationship between organizational commitment and each aspect of CSR is investigated within a model that distinguishes between genders and includes a set of control variables that is drawn from the commitment literature (Meyer et al., 2002 Meyer, J.P., Stanley, D.J., Herscovitch, L. and Topolnytsky, L. 2002. Affective, Continuance, and Normative Commitment to the Organization: A Meta-Analysis of Antecedents, Correlates, and Consequences. Journal of Vocational Behavior, 61: 20–52. [Crossref], [Web of Science ®] , [Google Scholar]). The analysis is based on a sample of 4,712 employees drawn from a financial services company. The results emphasize the importance of gender variation and suggest both that external CSR is positively related to organizational commitment and that the contribution of CSR to organizational commitment is at least as great as job satisfaction.     

Administration costs of intravenous chemotherapy in treating peripheral T-cell lymphoma

Objective:

This retrospective cohort analysis was conducted to examine the cost components of administering IV chemotherapy to peripheral T-cell lymphoma (PTCL) patients in the US to inform decision makers.

Methods:

Patients diagnosed with PTCL (ICD-9 code 202.7X) between 1 October 2007 and 30 September 2012 were identified from a US administrative claims database. Costs for patients receiving at least one NCCN recommended IV chemotherapy were assessed using the allowed payment from claim line items, categorized into cost components (study drug costs, IV administration costs and other visit-related services).

Results:

The mean costs to the payer for IV cancer therapy administration in a PTCL patient population averaged about $5735 per visit and $9356 per member per month (PMPM). Across all therapies, mean IV administration costs accounted for $127–$794 per visit and $594–$1808 PMPM, contributing an additional 2–32% to the total costs of the drug alone. Mean other visit-related services costs for treating PTCL accounted for $70–$2487 per visit and $444–$3094 PMPM, contributing an additional 2–74% to the total costs. Combined, these additional costs represent an additional mean cost of $220–$3150 per visit and $1193–$4609 PMPM to the base price of the drug alone.

Limitations:

This study used a convenience sample to identify PTCL patients and only included visits where at least one NCCN recommended IV chemotherapy was administered.

Conclusions:

The costs of IV administration and other visit-related services add measurable costs to the total cost of IV therapy for treating PTCL. When considering the cost of the drug, these additional costs can represent a substantial proportion of the overall costs and must be considered when evaluating the costs of IV treatment options for PTCL.     

From overt provider to invisible presence: discursive shifts in advertising portrayals of the father in Good Housekeeping, 1950–2010

Abstract

This article considers the link between fatherhood and masculinity and identifies some of the key discursive shifts around fatherhood based on an analysis of advertising material that appeared in Good Housekeeping magazine between 1950 and 2010. It provides a socio-historical perspective on fatherhood that reveals a discursive shift from the father as patriarchal family provider/protector to a more ambiguous and less obvious presence in the magazine advertisements. Our findings suggest that family-related advertising in women’s magazines does little to challenge the traditional models of paternal masculinity. Changes in the portrayal of fathers, when examined closely, seem to reinforce traditional gender hegemony. Yet, over time, a ‘multiplicity of possibilities’ of dominant paternal masculinities is emerging, broadening the original ‘breadwinner’ model and perhaps offering some transformative potential around how we view fathers.     

Labor markets and cultural values: Evidence from Japanese and American views about caregiving immigrants

One overlooked reason for the persistence of distinct cultural values across rich democracies, we argue, is a country's labor market structure. Parents seeking to position their children for long‐term success would do well to instill values consistent with requirements of the labor market in the country where their children are likely to work. To the extent that labor markets are fluid, as in the United States, parents should teach their children to be resourceful and creative. In countries like Japan with relatively rigid labor markets, where workers have one chance to land a long‐term contract with a leading company, parents instead should instill the values of hard work and respect for authority. We find evidence consistent with this argument in survey experiments about attitudes in the United States and Japan about the desirability of employing immigrants for care work, and what values the immigrant care workers should hold. We also find evidence of indirect norm creation. American and Japanese respondents prefer immigrants—not just caregiving immigrants—whose values align with their country's type of valued human capital.     

What is the role of consensus statements in a risk society?

Abstract

This paper explores the role of consensus statements in a risk society. It uses Beck’s theory of risk to show that scientists have employed consensus statements in order to re-establish faith in science. Through analysing the goals of participants in consensus fora and comparing them to the fora processes, this paper considers how consensus statements and guidelines in public health can be viewed as remedies for the decline in expert trust experienced in the current risk society. To collect data, 25 interviews were undertaken with consensus panel participants from the USA, UK and Australia. Interviewees were from peak national agencies/commissioning agencies and were categorised as policymaker, practitioner and consumer stakeholders. Participants made recommendations for improving consensus processes in order to mitigate perceptions of risk. These were: (1) clearly stated goals; (2) robust, evidence-based and transparent processes of methodological development and participation/deliberation/decision-making; (3) diverse stakeholder representation, including increased consumer participation; (4) transparency about conflicts of interest; and, (5) robust, carefully worded recommendations. Poor-quality consensus statements can further entrench scepticism about the scientific enterprise. While consensus statements can be seen as a tool for moderating perceptions of risk, policymakers and scientists must ensure the integrity, strength and transparency of their research methods. This has the potential to facilitate policy, improve scientific accountability to the public and legitimise processes. While fostering greater trust is not a primary objective for scientists, an increase in legitimacy of process can be an important unintended consequence of improved quality consensus statements and an important antidote to the risk society.     

The real problem: The deadly combination of psychologisation,scientism, and normative promotionalism takes strategic human resource management down a 30‐year dead end

This paper engages with Troth and Guest (2019) on psychology in HRM. I argue they misframe the central issue in debate. The real problem is not psychology per se but psychologisation—the drive to reduce explanation of macro‐level HRM outcomes to individual‐level psychological‐behavioural factors and individual differences. Accordingly, the most visible and harmful effects of psychologisation are in strategic HRM and the HRM‐performance literature but Troth and Guest's defence of psychology does not cover them. I use this response to re‐establish that it is psychologisation, not psychology per se, that is the critics' focal concern and describe how the three‐decade advance of psychologisation, along with scholastic scientism and normative promotionalism, have created severe theoretical and empirical problems in the high‐performance research programme and taken the strategic HRM field down a 30‐year dead‐end. Suggestions for a turn‐around are provided.
