African women farmers are less likely than men to adopt improved crop varieties and management systems. This paper addresses two issues: How does gender affect technology adoption among African farmers? How does the introduction of new technologies affect women's well-being? Three conclusions come out of an extensive and critical review of the literature. First, African households are complex and heterogeneous. Second, gender roles within African households and communities cannot be simply summarized. Third, gender roles and responsibilities are dynamic; they respond to changing economic circumstances. The paper demonstrates the complexity and importance of efforts to design interventions for African women.  相似文献

Crafting an environment to foster integration in new product teams   总被引:1,自引:1,他引:0  
The integration of functionally diverse members in new product teams is a long-standing managerial challenge. This study addresses two questions to help meet this challenge: 1) how can the environment around teams be crafted to foster integration, and 2) does integration help teams to create superior or more advantageous new products? Based on a survey of 206 cross-functional new product teams, we learned that certain environmental factors (market-oriented reward system, planning process formalization, managerial encouragement to take risks, and managerial involvement in new product projects) facilitate integration in teams, which, in turn, leads to the creation of superior or more advantageous new products.  相似文献

Rapidly growing demand for agricultural land is putting pressure on property-rights systems, particularly in Sub-Saharan Africa, where customary tenure systems have provided secure land access. Rapid and large-scale demands from outsiders are challenging patterns of gradual, endogenous change toward formalization. Little attention has focused on the gender dimensions of this transformation. However this contribution, based on a 2008–09 study of land tenure in Uganda, analyzes how different definitions of land ownership – including household reports, existence of ownership documents, and rights over the land – provide very different indications of the gendered patterns of land ownership and rights. While many households report husbands and wives as joint owners of the land, women are less likely to be listed on ownership documents, and have fewer rights. A simplistic focus on “title” to land misses much of the reality regarding land tenure and could have an adverse impact on women's land rights.  相似文献

A framework is developed to analyze a spatially dependent economically significant pest problem emanating from a source and spreading via a carrier such as an insect. Transmission and/or source control to combat the pest or disease problem are explored. Alternative assumptions about the effectiveness of transmission control and the feasibility and costs, both social and private, of reduction of the pest population at the source are examined in an application of the model to controlling Pierce's disease in California wine grapes.  相似文献

The building sector is regarded as having one of the highest benefit-cost ratios from greenhouse gas (GHG) emission reduction strategies. However, because of uncertainties around household behaviour patterns, it is very difficult to assess and compare the GHG reduction impacts of different intervention schemes for whole housing stock. Intervention schemes include policy instruments such as incentives or rebates for energy efficient appliances or renewable energy, and regulatory building code requirements for energy efficiency. This paper presents a decision support tool based on mathematical diffusion that evaluates the adoption levels of different schemes or pathways towards reducing GHG emissions in housing stock. It is an extension of the Bass diffusion model that accommodates financial and non-financial benefits, ceilings of adoption and interactions between intervention options. The model capability was tested using a case study of seven suburbs in Brisbane, Australia, comprising of 25,000 houses and units. Estimates of GHG emission reductions to 2019 of a household rebate scheme for solar panels and a rebate scheme for solar hot water compared to a base case of no rebates were presented and analysed. Modelling also allowed identification of important characteristics of adoption trends that could assist policy makers and industry to substantially improve the design of effective intervention options.  相似文献

Abstract

Overcoming traditional tourism silos to develop long-term relationships with stakeholders is essential for transformational change. Adopting broader networks connects researchers to pertinent issues facing society, develops reciprocal capacities for learning, and creates inclusive sustainable partnerships. As critical tourism scholars and not-for-profit employees, we illustrate the journey of how we engaged collaboratively with diverse stakeholders, from businesses, not-for-profits and the university, to tackle issues of economic disadvantage and social exclusion. Critical hospitality and dialogue theory were adopted to provide a framework for the processes of collaboration, research, networking, and advocacy work for inclusive sustainable spaces. Drawing on our involvement with co-founding a collaborative research network, the Network for Community Hospitality, and analysis of data from two Ketso workshops and interviews with 41 network members, we present reflections on setting up and facilitating the network. In addition, two examples of collaborative Network activities are presented to illustrate the techniques and dialogic communication processes for doing critical hospitality. The article thereby contributes by providing empirically informed and reflexive understandings into the experiences of working and communicating within long-term inclusive partnerships with diverse stakeholders to create traction for positive social sustainable change.  相似文献

Canadian exports of beef and live cattle to the United States have increased significantly since the late 1980s. Hog and pork exports have increased since the mid-1990s. Major factors affecting exports of beef, pork, cattle and hogs from Canada to the United States include the exchange rate, increased Canadian production, Canada-U.S. price differentials and trade liberalization under the Canada-United States Free Trade Agreement of 1989. Increased Canadian exports have resulted in small but significant reductions in U.S. domestic prices of beef, pork and hogs.  相似文献

The aim of this study was to determine the knowledge and acceptability of soymilk (defined as consumption pattern/usage and taste) by adult consumers, residing in different socio‐economic areas (low vs. high) in Cape Town. The study population of 214 participants were selected using convenience sampling. A questionnaire was developed in order to obtain demographic data (four items); basic general knowledge of soymilk (four items); and acceptability of the tested products (consumption patterns and taste) (eight items). There was a significant difference between the two groups (P = 0.000) regarding basic knowledge of soymilk, with significantly more in the high socio‐economic area (HSEA) having a score of at least 75%. Gender (P = 0.082) and age (P = 0.122) did not have a significant impact on the consumption patterns of soymilk. There was no significant difference between the two groups with respect to current usage (P = 0.228) and frequency of use (P = 0.213) of soymilk. However, a significantly smaller group (P = 0.000) of participants in the low socio‐economic area had previously tasted soymilk compared with those in the HSEA (16.7% vs. 41.5%; P = 0.000). In conclusion, socio‐economic status appeared to be associated with knowledge of soymilk. No significant differences with regard to gender, age or current usage in the two groups studied were noted.  相似文献

During the past five years, Kimberly‐Clark (K‐C) has faced a familiar management challenge: How can senior managers bring the rigor and discipline used to make daily operating decisions to the uncertain and risky world of innovation? The challenge was particularly acute at K‐C because the company is well known for its reliance on Return On Invested Capital (ROIC) and Discounted Cash Flow (DCF), both measures that are widely believed to lead to undervaluation of projects with risky upside potential. This article discusses how and why K‐C adopted and now uses the real options approach to project evaluation and management. The authors also share some lessons learned during the adoption process, including how the company adapted the real options framework to its own circumstances and requirements. The K‐C experience shows that successful adoption rests on a number of factors that have less to do with the rigor or precision of quantitative models than with matters of corporate process and organizational design.  相似文献
