The purpose of this paper is to examine psychological attachment styles (secure, anxious, and avoidant) as antecedents to leader-member exchange (LMX) quality both directly and through their impact on employees’ efforts to build high quality LMX relationships. Employees with secure attachment styles are proposed to be successful at building high quality LMX relationships while employees with anxious and avoidant styles are proposed to display the opposite effect.

Data were collected through a survey of 213 employees nested in 37 work groups. Hypotheses were tested using multilevel modeling within MPlus.

Results indicated that secure and anxious attachment styles were associated with LMX only by impacting the exertion of effort specifically aimed at relationship development with the manager. Alternatively, the avoidant style was directly and negatively linked to LMX but not associated with effort undertaken to build a high quality relationship.

The effects of attachment style on effort to develop high quality LMX relationships reveal that subordinate attachment style may impact those subordinates’ ability and interest in developing positive LMX relationships. Therefore, managers may need to purposively deviate from typical LMX development processes in order to create a more conducive environment for developing high quality relationships with subordinates of differing attachment styles.

This study is one of the first to examine the mediating impact of effort to build high quality LMX relationships given personal propensities (attachment style) to form relationships in the workplace.

Managing farm waste is a fundamental problem for farmers with economic, environmental and social impacts throughout the supply chain. Little research has explored innovative product solutions. This paper examines gleaning to reduce farm waste and proposes a resource-based Gleaning Innovation Framework which can lead to differentiated consumer products.

A multi-method approach, including descriptive company reviews, practitioner interviews and consumer surveys, evaluated how different participants in the food supply chain view the farm waste problem and the innovation of products through gleaning.

This research found that practitioners and consumers are cognizant and invested in reducing farm waste, with gleaning as a plausible solution. Future research includes gathering perspectives from retailers and other supply chain members, which may further develop the conceptualization of the gleaning innovation process.

Uniquely, the authors propose the Gleaning Innovation Framework that provides a platform for innovation across the supply chain to reduce farm waste. The research contributes to the farm waste debate with evidence that gleaning can assist the reduction of farm waste through product innovation. Developing innovations to reduce farm waste in sustainable and environmentally friendly ways would not only benefit the supply chain platform but also society.

Moringa (Moringa oleifera) is a highly nutritious, fast-growing crop that has emerged in Western markets as a “superfood” and as a “smart crop” for income generation potential among small-scale farmers. As such, moringa has been widely promoted by agricultural development practitioners in low-income countries and by emerging businesses aimed at achieving nutritional and social impact. However, the intrinsic nutritional and agronomic strengths of moringa are not enough to warrant its widespread promotion without first evaluating its economic potential to farmers.

A Land Use System (LUS) analysis modeling tool was employed to test the economic performance of two sets of moringa production practices in Kenya. Data were collected during in-depth interviews and field visits with farmers in Meru that supply a local market, and in Shimba Hills that supply an organic export market.

Results suggest that current production practices over an 12-years assessment period generate a Net Present Value (NPV) of US$8,049 [ha-1] in Meru and a negative NPV of US$697 [ha-1] in Shimba Hills; with average daily returns to family labor of these two production systems of roughly 1.6 times and 0.13 times the prevailing local wage rate, respectively. These differences were attributed to a higher farmgate prices and greater yields in Meru. The analysis tool was then used to predict the effects of changes in farming practices, e.g. if farmers in Meru switched to intensive bed cultivation NPV is estimated to increase by ∼650%.

This study demonstrates the importance of examining the economic performance of agricultural production systems intended to increase the benefits to small-scale farmers.

Our study is the first to assess moringa's economic performance within two production systems in Kenya – a local farmers' cooperative in Meru, and a group of farmers contracted by an export company.

USDA direct and guaranteed farm loan programs exhibit significant geographical variation in lending activity. County‐level estimations made using Tobit procedures indicate that use of Farm Service Agency (FSA) farm loan programs is greater in counties with lower per capita income and regions experiencing greater farm financial stress. Use of direct FSA loan programs was lower in counties with fewer private‐sector lenders. Guarantee loan program usage was found to decline when commercial agricultural lenders are absent from the county. FSA loan programs were more highly utilized in counties with an FSA loan service center and in states receiving greater FSA farm loan funding in past years.

Agricultural credit markets are dominated by two institutional retail lender groups, the cooperative Farm Credit System (FCS) and commercial banks. Analysis of farm loans made over the 1991S1993 and 2001S2002 periods indicates that FCS lenders were more likely to serve full‐time commercial farmers and farmers located in regions with less competitive credit markets. In contrast, commercial banks were more likely to serve small, part‐time, and hobby farmers. This segmentation of farm credit markets is consistent with federal regulations requiring the FCS to provide credit to “bona fide” farmers with a basis for credit.

This paper aims to examine impediments to the adoption of sustainable water-efficient technological innovation in agriculture. Farming is the largest water consumer and food production expansion in response to global population growth, combined with increasing droughts from climate change, threatens water and food insecurity for many countries. Yet, climate smart agriculture (CSA) innovation adoption has been slow, and in this regard, governments and the agricultural sector are not fulfilling their social responsibility and sustainability obligations.

Barriers to water-efficient drip irrigation (DI) adoption in Australia were investigated via 46 depth interviews with agricultural stakeholders and a survey of 148 farmers.

While DI water efficiency is recognised, this is not the key determinant of farmers’ irrigation method selection. Complex interrelationships between internal and external barriers impede DI adoption are identified. These include costs, satisfaction with alternative irrigation methods, farmer characteristics that determine the suitability of the innovation and the extent it is incremental or radical, plus various multidimensional risks. Government support of alternative, less water-efficient irrigation methods is also a critical barrier.

A conceptual framework for understanding barriers to sustainability oriented innovation adoption is presented. Its insights should be applicable to researchers and practitioners concerned with understanding and improving the adoption of socially responsible and sustainable innovation in a wide range of contexts. Recommendations for overcoming such adoption barriers are discussed in relation to the research focus of water-efficient agriculture and encouraging uptake of DI.

The purpose of the present research is to examine the comparative values that urban Vietnamese consumers place on attributes of rice that is produced using environmentally friendly methods. The authors consider the impacts that this may have on the livelihoods of rural Vietnamese small farmers. Rice is an “impure public good” that includes both “private” and “public” attributes that consumers consider in their purchase decisions. Consumers make tradeoffs between environmentally and socially beneficial practices (public goods) and perceptions of product quality (private goods). The authors used latent class modeling to investigate the values associated with attributes of rice that is produced using sustainable farming practices.

The authors used a discrete choice experimental design in which consumers stated their choices among combinations of rice attributes. The survey provided responses from 360 urban Vietnamese consumers and allowed to estimate the preferences and nonpecuniary values for rice grown using different levels of environmentally beneficial production methods.

The results identify two segments of rice consumers: one group of consumers who are sensitive to price and the other group who are sensitive to environmental issues. The individual characteristics are reflected in the choices of production methods and in the willingness to pay for environmentally beneficial outcomes of those methods.

Given the number of independent variables measured, the sample was relatively small, such that confirmatory statistical methods were inconclusive. However, the authors used multiple analytical tools that provide corroboration of the significant determinants of the utility functions for the two segments.

The results provide directions for production of rice at a national level, as well as practical implications for consumer-oriented communications.

Results suggest that the emerging middle class of Vietnamese consumers are willing to pay more for rice that is produced using methods that are beneficial to the environment. Results also indicate challenges to provide sustainably-produced rice to poorer groups of consumers.

The study provides important context for consumer preferences within emerging economies. This also adds to a growing literature that uses the choice experiment method to estimate consumer valuation of the outcomes of various agricultural practices.

The question of violence in hunter-gatherer society has animated philosophical debates since at least the seventeenth century. Steven Pinker has sought to affirm that civilization, is superior to the state of humanity during its long history of hunting and gathering. The purpose of this paper is to draw upon a series of recent studies that assert a baseline of primordial violence by hunters and gatherers. In challenging this position the author draws on four decades of ethnographic and historical research on hunting and gathering peoples.

At the empirical heart of this question is the evidence pro- and con- for high rates of violent death in pre-farming human populations. The author evaluates the ethnographic and historical evidence for warfare in recorded hunting and gathering societies, and the archaeological evidence for warfare in pre-history prior to the advent of agriculture.

The view of Steven Pinker and others of high rates of lethal violence in hunters and gatherers is not sustained. In contrast to early farmers, their foraging precursors lived more lightly on the land and had other ways of resolving conflict. With little or no fixed property they could easily disperse to diffuse conflict. The evidence points to markedly lower levels of violence for foragers compared to post-Neolithic societies.

This conclusion raises serious caveats about the grand evolutionary theory asserted by Steven Pinker, Richard Wrangham and others. Instead of being “killer apes” in the Pleistocene and Holocene, the evidence indicates that early humans lived as relatively peaceful hunter-gathers for some 7,000 generations, from the emergence of Homo sapiens up until the invention of agriculture. Therefore there is a major gap between the purported violence of the chimp-like ancestors and the documented violence of post-Neolithic humanity.

This is a critical analysis of published claims by authors who contend that ancient and recent hunter-gatherers typically committed high levels of violent acts. It reveals a number of serious flaws in their arguments and use of data.

Building on the risk balancing theory and on recent discussions the appropriateness of using farm income maximization as behavioural assumption, this paper extends the risk balancing framework by accounting for business-household interactions. The purpose of this paper is to theoretically introduce the concept of farm household risk balancing, a theoretical framework in which the farm household sets a constraint on the total household-level risk and balances farm-level and off-farm-level risk.

The paper argues that the risk behaviour of farmers is better understood by considering risk at the household level. Using an analytical framework, equations are derived linking the farm activities, off-farm activities, consumption and business and private liquidity.

The framework shows that a farm household that wants to minimize the risk that total household cash flow falls below consumption needs, may exhibit a wide variety of behavioural responses to changes in the policy and economic environment.

The framework suggests multiple ways for policy makers and individual farmers to support risk management.

Risk management is at the core of the agricultural policy and it is of paramount importance to be able to understand behavioural responses to market and policy instruments. This paper contributes to that by suggesting that the focus of current risk analysis and management studies may be too narrowly focused at the farm level.

Cassava production surged noticeably in Southeastern Africa beginning in the 1990s. The purpose of this paper is to examine the commercial responses and food security consequences of cassava production growth in the region.

The paper incorporates a mix of quantitative analysis, based primarily on original analysis of national farm household survey data, together with key informant interviews with value chain participants in the three neighboring countries of Malawi, Mozambique and Zambia.

In the cassava production zones, cassava's high productivity translates into per kilogram carbohydrate costs 60 per cent to 70 per cent of the cost of cereals such as maize and wheat, thereby opening up a range of profitable opportunities for commercialization of cassava‐based foods, feeds and industrial products. Despite this potential, cassava commercialization in Southeastern Africa remains in its formative stages, with only 10 per cent to 30 per cent of production currently marketed. Unlike West Africa, where cassava commercialization has centered on marketing prepared cassava‐based convenience foods, the emerging cassava markets in Southeastern Africa have centered on fresh cassava, low value‐added cassava flour, and experiments in industrial processing of cassava‐based starches, biofuels and feeds. Strategic investment in a set of key public goods (breeding, training in food sciences and food safety, and research on in‐ground cassava storage) can help to shape this transition in ways that benefit both commercial interests and the food security of vulnerable households.

The paper compares cassava commercialization across differing agro‐climatic zones, policy environments and food staple zones.
