Abstract: This paper examines the role of human capital and establishments’ practices in fostering food industry innovation across 13 low and middle-income countries. We estimate average marginal effects that also control for the variables traditionally recognized as affecting firm-level innovation, such as R& D expenditures. Our results suggest that establishments’ human capital endowments, such as top managers’ experience in the food industry and employees’ education, alone may not be sufficient to achieve high levels of innovation. In fact, human capital endowments are found to be more effective in delivering innovation when they are combined with establishments’ best practices such as providing employees slack time i.e., allocation of work-time on self-chosen projects of personal interests. Our key recommendation to food firms is to support employee slack time and human capital endowments as mutually reinforcing drivers of innovation.

Abstract: Research on the collaboration–innovation nexus emphasises that collaborations and innovation are multidimensional. Despite this emphasis, there is limited evidence on how firms' collaborative ersity affects their innovation ersity. This paper addresses this gap by examining the relationships between (i) a firm's functional ersity of collaboration (FDC) and innovation ersity, and (ii) innovation ersity and firm growth. We used longitudinal data from 738 Australian food firms, and our findings suggest that the positive relationship between FDC and innovation ersity reaches a point of saturation, beyond which additional collaboration negatively influences firms' innovation ersity. Moreover, innovation ersity depends on the motives behind alliance formation and the firm's focus on innovation. Finally, the association between innovation ersity and growth performance is heterogeneous across firms' conditional growth rate distribution.

Abstract: Despite growing interest in gender analysis in value chains, comparatively few studies have analyzed gender relations in small ruminant value chains using sex-disaggregated quantitative data in livestock-based systems. Drawing on baseline data from the Small Ruminant Value Chain Development Program (SRVD) in Ethiopia, this study aims to address two research questions: what is the gender status along small ruminant value chain stages and the related associations among aspects of empowerment and socio-economic variables? We employed empowerment and value chain frameworks to address these research questions. Our findings reveal that small ruminant market participation, related decisions, and control over income are gender differential. Estimation results identified several variables significantly associated with agency dimensions, achievements, or both, with mixed results. These are age group, context, being married, being men and head of household, participation in breeding stock selection, livestock ownership, contact with extension agents, access to market information, and participation in selling at marketplaces. Participation in a small ruminant value chain may encourage more egalitarian decision-making behaviors but does not guarantee the capacity to make autonomous decision-making, and thus needs to be coupled with interventions on empowerment dimensions. Nevertheless, further investigations are required to establish the mixed results with additional variables on norms.

Abstract: The purpose of this paper is to guide commercial and policy action to improve smallholder Indonesian cattle systems. A survey ( n = 304) of smallholder cattle farms in six villages in two districts of Nusa Tenggara Barat, Indonesia. Principal component analysis (PCA) and cluster analysis (CA) were employed to classify cattle farms into business models according to observed innovation. Differences between business models were identified using a one-way-analysis-of-variance (ANOVA). Four business models were identified, representing profiles of innovation adoption and elements of business models, socio-economic characteristics, farming system and performance variables including revenue, cost and profit. The business models display a range of orientation to buyer requirements and a range of approaches to production, indicating a need to promote in a variety of ways the change from supply-push to demand-pull in the cattle value chain. This study offers guidance on how business models might be strengthened over time, by using simple indicators of performance and the models' linkage to innovation in the context of each business model. The business models developed here, and refinements to them based on localised conditions, offer a targeted and accelerated pathway to improved performance in smallholder systems. This study proposed a novel approach to the recognition of business models based on innovation.

Abstract: This paper aims to address the association between the quality and quantity of information in supply chains and the costs and benefits of generating, using and sharing it. The authors’ conceptual framework draws on multiple disciplines and theories of the value and use of product information. Controllable aspects of information, its quality and quantity, are the focus of the study as drivers of firm and chain performance. Structural equation models of constructs at two stages of the Australian red meat supply chain are employed, using data from a survey of 81 sheep and cattle breeders and commercial producers. Information quality influences performance more for some product attributes than others and is more influential than is information quantity. Information sharing for many attributes generates benefits only at high cost. Investment in measurement and transmission technologies is supported for intrinsic and extrinsic measures of quality. Differences in respondents' evaluation of information quality are interpreted as evidence of persistent chain failure. To the authors' knowledge, this is the first attempt at quantifying and comparing the benefits and costs of information sharing across multiple stages of a supply chain and the first to assess quantitatively the role played by information quality and quantity in generating costs and benefits.

Abstract: Women's empowerment constitutes an important aspect of the development agenda. Although it is highly contextual in nature, empowerment literature so far has focussed on identifying factors associated with empowerment, neglecting the importance of understanding which empowerment resources and agency dimensions are more important for whom and under what contexts. This is important, because we cannot talk of empowerment for those who are not in a disempowered condition or who do not value it. We examine the gender differences in the relative valuations of empowerment resources and decision-making areas across different farming systems, and examine the most valued empowerment resources. Using a mixed methods approach, data on major household decisions, empowerment resources, and their relative importance were collected. Pairwise ranking methods were used to assess their gendered relative importance. In idual interviews using Ryff’s psychological well-being (PWB) items were conducted to obtain quantitative data on the key empowerment resource, which emerged as an important aspect of empowerment from the pairwise ranking exercises. Drawing on the empowerment framework and self-determination theory, we analysed the data. Our results show that the major empowerment resources and decision-makings that are valuable to men and women vary across gender and farming systems. In general, men place a greater importance on decisions about livestock, crop and finances. The women valued decisions regarding crop, livestock and social relations. Regarding empowerment resources, psychological well-being was found to be one of the most important resources, for women as well as men. Assessment of the basic psychological needs―autonomy, self-acceptance, and positive relations―statistically yielded no significant differences between the gender groups. However, the effects of location and the intersection of location with gender were both found to be statistically significant, suggesting that being men and from Horo is associated with higher scores on self-acceptance and personal relation subscales. We conclude that gender and location play important roles in forming contextual conditions for empowerment and agency implying that empowerment efforts need to consider both. More specifically, policies and intervention efforts to empower in iduals or groups must begin by first building their psychological assets and consider contextual gendered perceptions of resources.

Abstract: Intracerebroventricular (ICV) infusion of basic fibroblast growth factor (FGF-2) at 50 ng/h for 5 days in male BALB/c mice suppressed the daily intakes of water and food (n = 4). Intakes were reduced on the second day, and were suppressed until the second day after stopping the infusion. The same infusion for 4 days had little effect on the high intakes of 0.3 M NaCl solution and water induced by prolonged ICV infusion of angiotensin II, or the daily food intake in these experiments (n = 7). However, the same infusion for 3-4 days reduced the increased intake of NaCl solution in Na-depleted mice (n = 8), reduced the increased water intake of water-restricted mice (n = 6 or n = 7), and reduced daily food intake in both experiments. Ventricular enlargement was noted in mice at the end of these experiments but, for reasons advanced, did not appear to account for the responses. The results indicate that FGF-2 may have an inhibitory role in these ingestive behaviours.

Abstract: This paper proposes a framework for identification of business models in smallholder cattle production and marketing that represents innovation behaviour. Cattle are vital to Indonesia’s smallholders’ livelihoods, and smallholder systems are key to serving the country’s growing demand for beef. Business incentives currently select against the development and sustainability of breeding systems which would support domestic production, and so new models are needed which utilize innovation. The three primary components of a business model are presented: its value proposition, its value architecture, and its financing mechanism. A research approach is provided, by way of mapping data needs to the business models, and proposing relationships between observed innovation practices and the business models within the value chain. For implementation, the paper provides guidance on facilitation needs and the role of stakeholders in the case of the Indonesian cattle and beef value chain.

Abstract: Development efforts have increased women’s perceived empowerment and freedom, yet have failed to sustainably alter gender norms. There is a lack of research investigating reasons for this anomaly. This study, departing from the conventional approach, tries to fill this gap by employing an interpretative phenomenological approach to assess how women have managed to achieve expanded agency while living within a constraining normative environment. We argue that women have the capacity to deviate and the intentions that lead to new behaviors emerge not only from in iduals’ attitudes, subjective norms, and perceived behavioral control, as suggested by the Theory of Planned Behavior, but also in combination with demographic and economic factors. In iduals need to make decisions in three areas ―self-conviction (attitude and perceived behavioral control), subjective norms (within household and community), and structures (state and non-state institutions). The results shed light on alternative empowerment pathways that could potentially inform the design of transformational interventions.
