Child dietary quality in rural Nepal: Effectiveness of a community-level development intervention

Nutrition-sensitive agricultural interventions have the potential to improve child dietary quality in rural households, as evidenced by a growing body of work which concurrently measures agricultural and nutrition indicators. Our objective was to investigate whether children in rural farming communities of Nepal participating in a community-level, nutrition-sensitive development intervention had improved dietary quality compared with children living in non-participating matched rural communities. Six rural communities of Nepal where livelihoods were predominantly agricultural were selected to participate in the phased implementation of a community-level development intervention by Heifer International. Households and children in each community were surveyed at baseline, and follow-up surveys were implemented every six months for twenty-four months. Detailed data on food consumption for children older than 6 months of age were collected using a 24 h recall for 17 foods and food groups; parents responded for children. A difference-in-differences model with household fixed-effects and an analysis of covariance model were used to analyze the resulting panel data. Results indicated that the impacts of the intervention varied by agro-ecological region and by season. In the Hills region, which is poorer on average and more conducive to livestock production, children who had received the intervention for two years were 2.2 times as likely to have consumed food from an additional food group, 1.27 times as likely to have achieved minimum dietary diversity and 1.38 times as likely to have consumed animal source foods as children who received the intervention for only one year. In the Terai region, which is more conducive to crop production, there was no significant change in dietary quality attributable to the intervention. These results provide evidence that particularly vulnerable families can take advantage of community-level development activities. Given that the effects of community-level development activities were disparate across communities within the same country, we conclude that tailoring development activities for particular locations is necessary for success.     

The effect of smileys as motivational incentives on children’s fruit and vegetable choice,consumption and waste: A field experiment in schools in five European countries

To assess whether smiley stamps work as a motivational incentive to promote fruit and vegetable eating among children, we conducted a field experiment in ten primary schools in five European countries using one control and one treatment school per country. The six-week experiment was split into three two-week phases before, during and after the smiley was implemented. During the smiley phase, the children received a smiley stamp for choosing a portion of fruits or vegetables. We find an increase attributed to the smiley stamp on children’s fruit and vegetable choice and consumption, but also waste. Comparing the effects across countries, we observe significant variations in the smiley effect. This study thus demonstrates, in general, that a low-cost, easy-to-implement incentive such as a smiley stamp has the potential to motivate school children to increase their fruit and vegetable consumption; the study simultaneously underscores the high relevance of context for the effects of incentives.     

Technological literacy for students aged 6–18: a new method for holistic measuring of knowledge,capabilities, critical thinking and decision-making

Technological literacy is identified as a vital achievement of technology- and engineering-intensive education. It guides the design of technology and technical components of educational systems and defines competitive employment in technological society. Existing methods for measuring technological literacy are incomplete or complicated, unreliable, unstable and imprecise, time-consuming, and require large expenditures on resources. This paper presents a new method for valid and reliable measuring of technological literacy. The method encompasses three main components—knowledge, capabilities, and critical thinking and decision-making. It is centred on the standards for technological literacy issued by the International Technology and Engineering Educators Association. It has three key features. (1) A construct-measure-result front-ended approach, where a construct consists of an object, attribute, and entity; which causes reduction of measure-induced distortion and error. (2) A broad test range definition that provides stable and accurate measuring of technological literacy for 6–18-year-old students. (3) A genuine design approach including a multiple choice test item form determination consisting of content, criterion and construct validity, item discrimination, difficulty index, and an intraclass correlation measure for time stability and scooping its heterogeneous nature. Only the method is described herein and its pilot test results are presented. It is moderately reliable over time (intraclass correlation coefficient = 0.68, p < 0.05), has high criterion-related validity (r _xy  < 0.4) and construct validity (h ² > 0.7). High content validity evidence was ensured through a two-stage validation method, while test item discrimination coefficient values are acceptable (r _pbis  > 0.1). The method is time-efficient (measuring lasts 45 min), valid, stable, and enables holistic investigation of large sample sizes.     

Association of financial or professional conflict of interest to research outcomes on health risks or nutritional assessment studies of genetically modified products

Since the first commercial cultivation of genetically modified crops in 1994, the rapidly expanding market of genetically modified seeds has given rise to a multibillion dollar industry. This fast growth, fueled by high expectations towards this new commercial technology and shareholder trust in the involved industry, has provided strong incentives for further research and development of new genetically modified plant varieties. Considering, however, the high financial stakes involved, concerns are raised over the influence that conflicts of interest may place upon articles published in peer-reviewed journals that report on health risks or nutritional value of genetically modified food products. In a study involving 94 articles selected through objective criteria, it was found that the existence of either financial or professional conflict of interest was associated to study outcomes that cast genetically modified products in a favorable light (p = 0.005). While financial conflict of interest alone did not correlate with research results (p = 0.631), a strong association was found between author affiliation to industry (professional conflict of interest) and study outcome (p < 0.001). We discuss these results by comparing them to similar studies on conflicts of interest in other areas, such as biomedical sciences, and hypothesize on dynamics that may help explain such connections.     

Reconnecting Australian consumers and producers: Identifying problems of distrust

A growing gap between the production and consumption of food has led to a decline in consumer trust in food, and a desire for increased regulation of food. The aim of this study was to investigate the nature of consumer trust in food production and regulation in the wake of shifts in food technology, globalisation and production. Semi-structured interviews (n = 47) were conducted in 2009 with participants living in rural and metropolitan South Australia. Rural participants were more trusting of food production because of their direct experience with producing food than their metropolitan counterparts. Consumers’ embeddedness in food production impacts their trust in food. Increasing local food production and consumption may increase consumer trust in food, and decrease consumer dependence on government regulation.     

Farm production diversity is associated with greater household dietary diversity in Malawi: Findings from nationally representative data

Farm production diversity has the potential to influence the diversity of household diets, an important nutrition outcome associated with the nutrient adequacy of diets and the nutritional status of individuals. Yet, little empirical research has assessed the relationship between farm diversity and diet diversity or the plausible causal mechanisms that may operate between these two constructs. This research examines cross-sectional data from the Malawi Third Integrated Household Survey (IHS3), a nationally representative sample of farming households in Malawi, implemented from March 2010–March 2011 as part of the World Bank Living Standards Measurement Study – Integrated Surveys on Agriculture (LSMS-ISA). These data were used to determine the relationship between farm production diversity and household dietary diversity, and to identify determinants of this relationship. Two indicators of dietary diversity, a modified Household Dietary Diversity Score (HDDS), and the Food Consumption Score (FCS), were calculated along with three indicators of farm production diversity including the Simpson’s Index, a metric accounting for both species richness and evenness. In multiple regression analyses, adjusting standard errors for the complex survey design of the IHS3 and controlling for the effects of several covariates on household dietary diversity, farm production diversity was consistently positively associated with dietary diversity (P < 0.0001). The association of increased farm diversity as measured by a combined crop and livestock measure on dietary diversity was significantly greater in woman-headed households compared to those headed by men (HDDS: P = 0.008; FCS: P = 0.076). The positive association of farm diversity with dietary diversity was also greater in wealthier households (P < 0.05). Consumption of legumes, vegetables and fruits was especially strongly associated with greater farm diversity. More diverse production systems may contribute to more diverse household diets. However, this relationship is complex; it may be influenced by gender, wealth, control of household decisions, the relative market-orientation of a household’s agricultural production, and the specific nature of farm diversity.     

The cost,coverage and rollout implications of 5G infrastructure in Britain

Despite 5G still being embryonic in its development, there is already a quest for evidence to support decision-making in government and industry. Although there is still considerable technological, economic and behavioural uncertainty, exploration of how the potential rollout may take place both spatially and temporally is required for effective policy formulation. Consequently, the cost, coverage and rollout implications of 5G networks across Britain are explored by extrapolating 4G LTE and LTE-Advanced characteristics for the period 2020–2030. We focus on ubiquitous ultrafast broadband of 50 Mbps and test the impact of annual capital intensity, infrastructure sharing and reducing the end-user speed in rural areas to either 10 or 30 Mbps. For the business-as-usual scenario we find that 90% of the population is covered with 5G by 2027, but coverage is unlikely to reach the final 10% due to exponentially increasing costs. Moreover, varying annual capital intensity or deploying a shared small cell network can greatly influence the time taken to reach the 90% threshold, with these changes mostly benefiting rural areas. Importantly, simply by integrating new and existing spectrum, a network capable of achieving 10 Mbps per rural user is possible, which is comparable to the UK's current fixed broadband Universal Service Obligation. We contribute to the literature by quantifying the effectiveness of the spatial and temporal rollout of 5G under different policy options.     

Social media as a useful tool in food risk and benefit communication? A strategic orientation approach

Although considerable progress has been made in understanding the determinants of risk perception and in identifying the necessary components of effective food risk and benefit communication, this has not been matched with the development of efficient and appropriate communication tools. Little work has been done examining the implications of the explosion of new media and web technologies, which may offer potential for improving food risk and benefit communication. First, this study examines the views of stakeholders (n = 38) and experts (n = 33) in the food domain on the potential use of these emerging media for food risk/benefit communication. Based on in-depth interviews in six European countries (Belgium, Ireland, Italy, Latvia, Spain and The Netherlands), strengths, weaknesses, opportunities and threats (SWOT) of social media in food risk and benefit communication were identified. Second, a Strategic Orientation Round (SOR) was used to evaluate the relative importance of the SWOT components according to stakeholders (n = 10) and experts (n = 13). Results show that both stakeholders and experts confirm a future role of social media in food risk and benefit communication. Strengths as speed, accessibility and interaction make social media an interesting tool in crisis communication or issue awareness raising. Weaknesses as the lack of a filter, low trust, the risk of information overload and a communication preference for traditional media are acknowledged.     

Deliberate learning as a strategic mechanism in enabling channel partner sales performance

As suppliers increasingly depend on their indirect sales channel, enablement of channel partners has become a strategic asset. We focus on the central role of deliberate learning within strategic enablement strategy. Specifically, we conceptualize deliberate sales learning as a three-dimensional construct (knowledge articulation, knowledge codification, knowledge certification) and identify the mechanisms through which it impacts on channel partner sales performance. Based on a survey of channel partners (N = 383) of an FT100 company, we establish exploitative and explorative learning orientations as antecedents of deliberate sales learning, where this relationship is moderated by channel partners' preference for online learning formats. The relatively weaker relationship between explorative learning orientation and deliberate sales learning is positively enhanced for those channel partners with a preference for interactive online modules. Further, we demonstrate that deliberate sales learning and deliberate sales practice act in serial mediation to positively impact sales performance. In addition to future research opportunities, we identify three core implications for the practice of strategic sales enablement; enhancing return on investment, managing learner motivation and activating learning engagement of channel partners.     

Eating to save the planet: Evidence from a randomized controlled trial using individual-level food purchase data

Meat consumption is a major driver of climate change. Interventions that reduce meat consumption may improve public health and promote environmental sustainability. We conducted a randomized controlled trial to examine the effects of an awareness-raising intervention on meat consumption. We randomized undergraduate classes into treatment and control groups. Treatment groups received a 50-minute lecture on how food choices affect climate change, along with information about the health benefits of reduced meat consumption. Control classrooms received a lecture on a placebo topic. We analyzed 49,301 students’ meal purchases in the college dining halls before and after the intervention. We merged food purchase data with survey data to study heterogenous treatment effects and disentangle mechanisms. Participants in the treatment group reduced their purchases of meat and increased their purchases of plant-based alternatives after the intervention. The probability of purchasing a meat-based meal fell by 4.6 percentage points (p < 0.01), whereas the probability of purchasing a plant-based meal increased by 4.2 percentage points (p = 0.04). While the effects were stronger during the semester of the intervention, dietary shifts persisted and remained statistically significant through the full academic year. Our study provides evidence that an intervention based on informing consumers and encouraging voluntary shifts can effectively reduce the demand for meat. Our findings help to inform the international food policy debate on how to counter rising global levels of meat consumption to achieve climate change goals. To our knowledge, our study is the first to assess the effectiveness of an educational intervention to reduce meat consumption using such high-quality data (i.e. individual-level food purchases) over a prolonged period.     

Altruism,reciprocity and health: A social experiment in restaurant choice

We used an experimental game to determine whether people imitate restaurant choice, reciprocate food gifts, and thus spread health choices. We randomly paired 138 subjects and recorded their decision to give or keep restaurant vouchers and their choice of restaurant. The majority (83.3%) chose an unhealthy restaurant if their randomly assigned partner chose an unhealthy restaurant. Similarly, 77.8% chose a healthy restaurant if their partner did (p = 0.005). The altruistic were more likely to choose a healthy restaurant (p = 0.017). In sum, restaurant choice is influenced by reciprocity. A cycle of projection, gifting and reciprocation may explain the social dynamics of food choice. We propose policies that capitalize on people’s tendency towards altruism and imitation.     

Validating the usage of household food acquisition surveys to assess the consumption of ultra-processed foods: Evidence from Brazil

Our ability to research dietary changes over time and their effects on health is limited by challenges in accurately measuring food consumption. In countries where dietary surveys are scarce and rarely nationally representative, household budget surveys may serve as a useful alternative for assessing food consumption. The objective of this study was to evaluate how well household acquisition data reflects the actual intake of ultra-processed foods, using data from the 2008 to 2009 Brazilian Household Budget Survey. The food acquisition module was conducted for all households selected for the survey (n = 55,970) and a subsample corresponding to 25% of the households (n = 13,569) was randomly selected for the individual food intake module, which was conducted for all individuals aged 10 years or older (n = 34,003). Ultra-processed foods were defined as formulations made by the food industry mostly or entirely from substances extracted from foods or obtained with the further processing of constituents of foods or through chemical synthesis, with little if any whole food. Examples included candies, cookies, chips, sugar-sweetened beverages, and ready-to-eat dishes. Our results showed an important agreement between the estimates of ultra-processed food consumption obtained from household acquisition data and individual intake inside-the-home data, particularly for the relative (% of total energy) consumption of these foods. Our study thus indicates that household budget surveys are quite promising for tracking population-level changes in the consumption of ultra-processed foods. The trend toward increased consumption of food away from home in other low- and middle-income countries indicates that future household budget surveys should include the collection of these data.     

Will they buy it? The potential for marketing organic vegetables in the food vending sector to strengthen vegetable safety: A choice experiment study in three West African cities

Considering the hazardous use of synthetic pesticides in vegetable production in urban West Africa, this research investigated the marketing potential of organic vegetables in the food vending sector of Cotonou (Benin), Accra (Ghana) and Ouagadougou (Burkina Faso). Certified organic production and marketing was examined as a potential strategy to improve chemical food safety. A stratified random sampling strategy was applied to study the preferences of food vendors (n = 180) and consumers (n = 360); vegetable use, risk perception, choice preferences and willingness-to-pay (WTP) for organic certification were specifically analyzed. The results showed that awareness of chemical contamination risks was generally low. Appearance of a product was central to vendor choice; consumers attributed similar utility to taste and organic certification. Consumer WTP was calculated to be a premium of 1.04 USD (per plate) if the food served contained only certified organic vegetables. In restaurants, this would mean an average premium of 19% for a meal. If certified organic vegetable production is to make a positive impact on food safety in urban West Africa, we suggest concentrating marketing efforts on the educated “elite” who frequent restaurants. However, considering that restaurant owners exhibited a lower preference for organic certification than lower class food vendors, the marketing situation is difficult. We therefore conclude that demand from the food vending sector alone will not institutionalize domestic certification mechanisms; this underlines the need for public commitment to facilitating such change.     

Indigenous Shawi communities and national food security support: Right direction,but not enough

Food insecurity is a major challenge facing Peru’s Indigenous Shawi communities, who receive food support through national level programs. There is limited research, however, on how national food and social programming support is perceived, received and used among Indigenous communities. We address this research gap by characterizing the preferred diet and coping mechanisms among Shawi Indigenous households, and investigating community perspectives on the national food program and national social supports. We used a mixed methods approach, including a quantitative survey among eleven Shawi communities in the Peruvian Amazon (n = 177 households), and semi-structured interviews with key informants (n = 24). We found that national food programs in Peru rarely provide foods that are desired and preferred among the Shawi, particularly familiar and locally-sourced protein sources such as bushmeat and fish. Food and social programming requirements do not integrate consideration of the remoteness of many vulnerable households, and are considered culturally or linguistically inaccessible to many families. In some cases, foods supplied by national programs are not consumed as they are perceived as unfamiliar. Key opportunities to improve food and social programing include: monitoring and revising eligibility requirements for remote and highly vulnerable households; increasing provision of locally-preferred protein food and familiar food types; avoiding use of written Spanish as a sole source of information to support programming; extending food provision outside of school months; developing contingency plans during education sector strikes; considering hiring of staff with working knowledge of local languages for community distributions; using visual or oral communication rather than written communication to increase accessibility of programs; increasing knowledge on the use and nutritional value of external food; and considering exemptions to school and health eligibility requirements during the rainy season and during sector strikes. Nationally-developed programming that does not consider Indigenous and cultural contexts risks inefficiency, limited improvement of health outcomes, and the potential to increase inequities in Indigenous health.     

Agricultural technology adoption and poverty reduction: A propensity-score matching analysis for rural Bangladesh

This study aims at shedding some light on the potential impact of agricultural technology adoption on poverty alleviation strategies. It does so through an empirical investigation of the relationship between technological change, of the Green Revolution type, and wellbeing of smallholder farm households in two rural Bangladeshi regions. As technology adoption is not randomly assigned but there is ‘self-selection into treatment’, the paper tackles a methodological issue in assessing the ‘causal’ effect of technology on farm-household wellbeing through the non-parametric ‘p-score matching analysis’. It pursues a targeted evaluation of whether adopting a modern seed technology causes resource-poor farmers to improve their income and decrease the propensity to fall below the poverty line. It finds a robust and positive effect of agricultural technology adoption on farm household wellbeing suggesting that there is a large scope for enhancing the role of agricultural technology in ‘directly’ contributing to poverty alleviation.     

How to Build an AI Climate-Driven Service Analytics Capability for Innovation and Performance in Industrial Markets?

AI climate-driven service analytics capability has been anecdotally argued as a viable strategy to enhance service innovation and market performance in B2B markets. While AI climate refers to the shared perceptions of policies, procedures, and practices to support AI initiatives, cognitive service analytics capability refers to the analytical insights driven by AI climate and augmented by both machines and humans to make marketing decisions. However, there is limited knowledge on the antecedents of such analytics capabilities and their overall effects on service innovation and market performance. Drawing on service analytics literature and the microfoundations of dynamic capability theory, this study fills this research gap using in-depth interviews (n = 30) and a survey (n = 276) of service analytics managers within the AI climate in Australia. The findings confirm the five microfoundations of cognitive service analytics capabilities (cognitive technology, cognitive information, cognitive problem solving, cognitive knowledge & skills, cognitive training & development). The findings also highlight the significant mediating effect of service innovation in the relationship between analytics climate and market performance and cognitive service analytics capability and market performance.     

Food accessibility,diversity of agricultural production and dietary pattern in rural China

The market-oriented reform in China in the past 4 decades has greatly reshaped the consumption pattern in rural areas. In particular, farmers’ diets are more likely to depend on food market development such as food accessibility. This study investigates the role of food accessibility in the transition of dietary pattern in rural China by using the China Health and Nutrition Survey data (1997–2011) and whether food accessibility helps alleviate the deviation between farmers’ dietary pattern and the recommended dietary pattern according to China Food Pagoda 2016. The primary results indicate that food accessibility contributes to improvements in quality. In particular, food accessibility increases the consumption of oil and decreases the consumption of cereal, potatoes, and beans; fruits; vegetables; and salt. Further estimation finds evidence that along with increasing food accessibility, fruit is converging to the recommended dietary pattern in China Food Pagoda 2016, and the deviations of legumes, nuts, and oil are increasing. We also observe that the impact of food accessibility on dietary quality is stronger for those not engaged in agriculture production. Our study provides valuable implications for rural development and nutrition security in the developing world.     

Food environments in Malta: Associations with store size and area-level deprivation

Food environments are potential targets for interventions to reduce obesity prevalence, particularly in island settings that are typically dependent on food imports. This observational study aimed to characterise the availability, quality and price of foods and beverages in a nationally representative sample of grocery stores in Malta using the Nutrition Environment Measures Survey for Stores (NEMS-S) instrument, and to examine the association between area-level density of different types of food stores and the likelihood of children living in these areas being overweight or obese. Fieldwork was carried out between March and May 2014. There was a strong positive correlation between store size and NEMS-S score (p = <0.001), suggesting that smaller grocery stores generally offered a smaller range of products and fewer healthy food/beverage options than larger supermarkets. Across all stores, median prices of certain ‘healthier’ versions of foods were more expensive than their less healthy alternatives. A significant association between risk of childhood overweight, and density of confectionery stores in children’s locality of residence, was found (OR 1.19; 95% CI: 1.04, 1.37). These baseline findings highlight opportunities to improve the food environment in Malta to support more healthful eating, and may be of particular interest to public health practitioners in island settings.     

“The more,the merrier” or “less is more”? How the number of issues addressed in B2B sales negotiations affects dyadic and seller economic outcomes

With a mixed-methods approach, this study analyzes how varying the number of issues in business-to-business (B2B) sales negotiations affects negotiation processes and outcomes. A qualitative interview study with B2B negotiators (N = 46) reveals that more issues increase complexity but offer more possibilities for concessions. Sellers see benefits in increasing the number of issues addressed, whereas buyers are ambiguous about whether negotiating more issues will benefit their economic outcomes. A second experimental study (N = 97 dyads) tests whether negotiating a different number of issues (four, eight, or between four and eight) produces different absolute and relative dyadic economic outcomes and sellers' shares of the joint profits in one-on-one negotiations. In absolute terms, more negotiation issues produce larger negotiation pies; fewer issues facilitate more accurate information processing, leading to relatively more integrative agreements. For sellers, increasing the number of issues increases their share of the joint profit, because buyers are more willing to concede on the overall price of the deal.
