Breaking ground: transformative partnerships for inclusive bean breeding in Zimbabwe

Common bean is often considered a woman’s crop because they play important roles from production to marketing. However, breeding programs often focus on farmers without adequate attention to the interconnectedness between gender and other socioeconomic variables and how they influence varietal and trait preferences of other value chain actors. This study analyzed gendered differences in bean production and trade, implications of socioeconomic conditions on bean production and marketing, and the role of partnerships in closing gender gaps in the bean value chain in Zimbabwe. The results obtained from the analysis of survey data collected from 131 farmers and 18 trades revealed beans as a dual-purpose crop for male and female farmers and traders. Varietal and trait preferences were the same for both male and female farmers and traders but were prioritized differently. While female farmers prioritized cooking time, men farmers prioritized biofortification and market traits. Whereas male traders equally preferred price, color, and appearance, female traders prioritized price over color and appearance. Poverty and marital statuses of respondents influenced the number of varieties preferred by male and female farmers. We found that the effectiveness of partnerships in closing gender gaps in marketing is variety specific. While having partners closed the gender gaps in the marketing of the NUA45 variety, such partnerships did not have the same effect on closing gender gaps in the marketing of Cherry, Gloria, and other varieties. The results show that considering socioeconomic characteristics of actors and partnerships can reduce gender disparities in the bean value chain. Therefore, breeding programs should recognize the interconnectedness between socioeconomic variables and gender when developing breeding products.

Exploring Domestic Reasons for Cooperation on the Hinkley Point C Nuclear Power Project

As a result of the Chernobyl nuclear power plant accident in 1986, the British public generally has a negative attitude towards nuclear power, coupled with the lobbying of Greenpeace and other organizations opposed to nuclear energy. Since the completion of the Sizewell B nuclear power plant in 1995, the UK has not built a single new nuclear power plant and has been lagging behind in nuclear energy construction. With climate change and security of supply issues coming to the fore, it was not until the 2006 Energy White Paper that the government put nuclear energy back on the agenda. It took another decades of planning, review and approval before the UK finally signed an agreement with Electricité de France for the construction of the Hinkley Point C nuclear power station in 2016. The UK has not built a new nuclear power project for more than 20 years, and this paper analyzes the attitudinal preferences of different actors within the UK behind the cooperation on the Hinkley Point C nuclear power project, based on an understanding of the context and current situation of the UK in terms of climate change and security of energy supply.

Is low-dose computed tomography for lung cancer screening conveniently accessible in China? A spatial analysis based on cross-sectional survey

BackgroundRegular Low-Dose Computed Tomography (LDCT) for lung cancer high-risk population has been proved to improve health outcomes and relieve disease burden efficiently for both individual and society. With geographical impedance becoming the major barrier preventing patients from getting timely healthcare service, this study incorporated health seeking behavior in estimating spatial accessibility of relative scarce LDCT resource in China, thus to provide real-world evidence for future government investment and policy making.MethodsTaking Sichuan Province in southwest China as the study area, a cross-sectional survey was first carried out to collect actual practice and preferences for seeking LDCT services. Using Computed Tomography (CT) registration data reported by owner institutions representing LDCT services capacity, and grided town-level high-risk population as demand, the Nearest Neighbor Method was then utilized to calculate spatial accessibility of LDCT services.ResultsA total of 2,529 valid questionnaires were collected, with only 34.72% of the high-risk populations (746 individuals) followed the recommended annual screening. Participants preferred to travel to municipal-level and above institutions within 60 min for LDCT services. Currently, every thousand high-risk populations own 0.0845 CT scanners in Sichuan Province, with 96.95% able to access LDCT within 60 min and over half within 15 min. Urban areas generally showed better accessibility than rural areas, and the more developed eastern regions were better than the western regions with ethnic minority clusters.ConclusionsSpatial access to LDCT services is generally convenient in Sichuan Province, but disparity exists between different regions and population groups. Improving LDCT capacity in county-level hospitals as well as promoting health education and policy guidance to the public can optimize efficiency of existing CT resources. Implementing mobile CT services and improving rural public transportation may alleviate emerging disparities in accessing early lung cancer detection.

The impact of LDC graduation on trade: A quantitative assessment

ABSTRACT Twelve Least-Developed Countries (LDCs) will graduate from the LDC status in the coming decade implying that they will lose preferential access to export markets. We quantify the expected impact of LDC graduation on exports of graduating and non-graduating LDCs incorporating detailed preference utilization data in a partial equilibrium model. We compare the results under actual and full preference utilization rates. Separately, we explore how underutilization of tariff preferences affects the exports of countries benefiting from such preferences. The analysis generates four main results. First, we project that graduation will have a negative impact on the exports of graduating LDCs (more than US$ 6 billion export loss or 6% of exports), especially in the clothing sector. Second, the adverse trade effects of graduation would be overestimated by 30% under full instead of actual utilization rates. Third, we show that the increase in exports of non-graduating LDCs following graduation of other LDCs is limited, implying that non-graduating poorer LDCs hardly benefit from graduation of richer LDCs. Fourth, we show that there would be significant benefits of increasing the utilization of LDC preferences. The exports of LDCs would increase by almost US$ 7 billions if they simultaneously switched to a full utilization regime.

AI regulation in the European Union: examining non-state actor preferences

AbstractAs the development and use of artificial intelligence (AI) continues to grow, policymakers are increasingly grappling with the question of how to regulate this technology. The most far-reaching international initiative is the European Union (EU) AI Act, which aims to establish the first comprehensive, binding framework for regulating AI. In this article, we offer the first systematic analysis of non-state actor preferences toward international regulation of AI, focusing on the case of the EU AI Act. Theoretically, we develop an argument about the regulatory preferences of business actors and other non-state actors under varying conditions of AI sector competitiveness. Empirically, we test these expectations using data from public consultations on European AI regulation. Our findings are threefold. First, all types of non-state actors express concerns about AI and support regulation in some form. Second, there are nonetheless significant differences across actor types, with business actors being less concerned about the downsides of AI and more in favor of lax regulation than other non-state actors. Third, these differences are more pronounced in countries with stronger commercial AI sectors. Our findings shed new light on non-state actor preferences toward AI regulation and point to challenges for policymakers balancing competing interests in society.

NUA 45, a dry bean cultivar, builds a subtle brand in Zimbabwe against all odds

Global business today is driven by brands, each with a unique story, but rarely of a product that is a public good. Building a brand requires careful planning, creativity, and an understanding of the target market. Borrowing from various brand concepts and frameworks, this paper explores how a government-bred common bean cultivar., NUA 45, defied the odds to create a new identity and association in Zimbabwe. Firstly, the cultivar overcame the general lack of promotion investment in government-bred (public) common bean cultivars. Secondly, being a red mottle-colored cultivar in a red-speckled (sugar type) bean-predominated country, NUA 45 had to break the preference typecasts. Thirdly, NUA 45 was among the first generation of biofortified bean cultivars enriched with iron (Fe) and zinc (Zn), some of the most sought-after micronutrients in a world ridden with hidden hunger. Overcoming these market barriers required a systematic approach to awareness creation, collaboration, and commercialization, avoiding the tragedy of the commons, and instead, achieving a win-win situation for all stakeholders. This entailed understanding the needs and preferences of different value chain actors, developing messages, and engaging local farmers, retailers, aggregators, and private and public sector partners to promote NUA 45. Lastly, developing compelling stories and leveraging digital channels to reach new customers that sought personal experiences, moved the cultivar name from a mere label to a spontaneously endorsed lifestyle and a brand that ‘spread like wildfire’ across the country and the Southern Africa Development Community (SADC) region. The NUA 45 brand broke new ground for other biofortified bean cultivars and non-sugar bean cultivars. Following its release in seven other countries, NUA 45 pioneered listing on the SADC regional variety catalog.

Mentor teachers’ descriptions of preferred actions related to scenarios describing emotionally challenging episodes in work-based learning

ABSTRACT Work-based learning is an influential period of teacher education, where a mentor teacher is assigned to support the student teacher. Mentoring conversations between the mentor teachers and student teacher seldom cover how student teachers cope with emotional challenges. Therefore, we aimed to investigate mentor teachers’ perspectives on student teachers’ reports of emotional challenges. The study had a particular focus on actions the mentor teachers described as preferable in reacting to scenarios of emotional challenges reported by student teachers. We conducted a constructivist grounded theory study and interviewed 22 mentor teachers. The findings of the study show that mentor teachers’ main concern revolved around student teachers’ understanding of challenges as learning opportunities. According to mentor teachers’ descriptions, the preferred actions in their role as mentor teachers were to regulate, engage/help, be exemplary, and take charge. Thus, our study shows that mentor teachers intended to aid student teachers in navigating emotional challenges.

Media actors as policy entrepreneurs: a case study of “No Jab, No Play” and “No Jab, No Pay” mandatory vaccination policies in Australia

The media’s central role in the policy process has long been recognised, with policy scholars noting the potential for news media to influence policy change. However, scholars have paid most attention to the news media as a conduit for the agendas, frames, and preferences of other policy actors. Recently, scholars have more closely examined media actors directly contributing to policy change. This paper presents a case study to argue that specific members of the media may display the additional skills and behaviours that characterise policy entrepreneurship. Our case study focuses on mandatory childhood vaccination in Australia, following the entrepreneurial actions of a deputy newspaper editor and her affiliated outlets. Mandatory childhood vaccination policies have grown in strength and number in recent years across the industrialised world in response to parents refusing to vaccinate their children. Australia’s federal and state governments have been at the forefront of meeting vaccine refusal with harsh consequences; our case study demonstrates how media actors conceived and advanced these policies. The experiences, skills, attributes, and strategies of Sunday Telegraph Deputy Editor Claire Harvey facilitated her policy entrepreneurship, utilising many classic hallmarks from the literature and additional opportunities offered by her media role. Harvey also subverted the classic pathway of entrepreneurship, mobilising the public ahead of policymakers to force the latter’s hand.

Into the ether or the state? Legibility theory and the cryptocurrency markets

AbstractThere is substantial cross-national variation in the level of regulatory clarity surrounding cryptocurrencies. What explains these differences? And, more broadly, what drives the divergent historical development of market regulation in different jurisdictions? To answer these questions, we present a new conceptual framework centered on the concept of market legibility. This term, inspired by the sociological literature, refers to the extent to which markets are made legible to the state through standardization. We contend that state supply of, and market demand for, legibility drives the primary political-economic dynamics of market regulation. Specifically, these factors combine to produce ideal type states of legibility that correspond to both distinct stages of market development and the relative level of regulatory clarity in any one jurisdiction. This framework is utilized to conduct a comparative historical analysis of cryptocurrency regulation in the EU, US, UK, and Japan. By performing these tasks, this article corrects the common assumption that states are constantly striving to impose their authority on unwilling markets. It demonstrates instead that state and private actor preferences to make markets legible vary, conditioning, in turn, the political economy of regulatory governance.

Expert opinion survey on Israel’s food system: implications for food and health policies

BackgroundWhile there has been increasing global recognition and impetus for action to transform food systems towards greater food security, sustainability and better health outcomes, Israel has only recently begun to focus on the diverse challenges of its food system and its potential for transformation.MethodsAn expert opinion survey (n = 50) on Israel’s food system was conducted as part of a larger study on the systemic features of Israel’s food system transition to understand its policy gaps and find strategies towards a healthy and sustainable food system. The survey ranks the relevance and importance of food system challenges and policy preferences. Policy implications are then examined by identifying potential priorities, gaps and dissensus.ResultsThe survey finds that there is a majority agreement (76%) that Israel’s food policies are lacking or severely lacking. Respondents relate strongly to both concepts of nutritional security (90% think that access to nutritious food is relevant or highly relevant) and national food security (more than 80% perceive food security as part of national security). Respondents overwhelmingly recognize the benefits of Israeli agriculture with 60–90% agreeing or strongly agreeing that it benefits food security, economic value and national identity. Top-ranked problems include overall systemic problems such as the lack of national goals, strategic planning, and integrated policymaking across ministries, and specific ones such as food waste, costly farming inputs, and food affordability. The most preferred policy actions include establishing a national strategy for food and agriculture, making food affordable for vulnerable households, and incentivising sustainable farming methods. The key policy gaps include the lack of resilience in agriculture and the food system, insufficient data and knowledge for policy action, inadequate attention to the regulation of the food industry for better health and inadequate food policy attention for minority groups.ConclusionsBuilding on this study's findings, further policy research and implementation areas to be covered include government responsibility for universal food security, strategic systemic policies for food systems, prevention and preparedness for future crises, and promoting resilience. The way forward may best be through an inter-ministerial committee with the responsibility, budgets, mandate and executive authority to plan data-driven policies for a sustainable food system for Israel’s future.

Different decision-making in spine metastasis management among radiation oncologists and orthopedic surgeons: a Korean online survey study.

To understand the current practice of radiation oncologists (ROs) and orthopedic surgeons (OSs) regarding spine metastasis. In 2022, an internet-based survey was conducted for ROs and OSs who treat spinal metastasis in Korea. Respondents were asked to choose the treatment option for two clinical scenarios. Scenario 1 involved a case displaying symptoms of leg weakness due to spinal cord compression and Scenario 2 involved a case with back pain due to pathologic compression fracture. The survey also included a question that required respondents to rank the importance of 11 clinical factors that affect treatment decisions. Forty-nine ROs and 30 OSs responded to the survey. There were significant differences in treatment choices between two groups for both scenarios (P = 0.001). In Scenario 1, more OSs chose surgical resection than ROs (43.3% vs. 16.7%), while more ROs chose radiotherapy than OSs (83.3% vs. 53.3%). In Scenario 2, a similar proportion of OSs and ROs chose radiotherapy (OSs, 71.4% vs. ROs, 67.3%), while more OSs opted for prophylactic fixation after radiotherapy than ROs (95.0% vs. 42.4%). The top three factors influencing treatment decisions were general performance status, life expectancy, and spinal instability for both ROs and OSs. In both Scenarios 1 and 2, the treatment decisions of ROs changed significantly when clinical conditions related to these top three factors were altered. Although ROs and OSs share the same factors influencing treatment decisions for spinal metastases, notable differences exist in their actual treatment preferences, with ROs preferring radiotherapy and OSs opting for surgical resection. Multidisciplinary discussions may be necessary to reduce the gap in decision-making.

Closing gender gaps through gender-responsive, demand-led breeding in Burundi.

Gender inequality persists in Burundi's agricultural sector, especially in the bean value chain dominated by women. Women often have less access to improved seeds and to productive technologies. Interventions dubbed "gender-responsive plant breeding" have been launched to develop new varieties to address the gender gaps in variety adoption. Gender responsive planting breeding in Burundi targets to develop bean varieties that respond better to gendered varietal and trait preferences. This paper provides a background of gender-responsive bean breeding in Burundi, documenting the methodologies that were used to integrate gender issues in bean breeding and socio-economic research. It also covers successes of gender-responsive breeding to date, primarily focusing the interdisciplinary teams that drove the process, development and release of varieties that incorporated traits favored by women and men actors. Evidence from surveys and value chain analysis reveal that gender-responsive breeding program increased the adoption of improved varieties by women and improved yields and productivity. The paper reveals that gender-responsive and demand-led bean breeding programs require stakeholders engagements to develop products that align with preferences of diverse actors at different nodes of the bean value chain.

How time flies: Time perception and intertemporal choice

This paper identifies a potential gap between time preference and intertemporal choices such as time discounting tasks: The intertemporal choices could be partly driven by a biased perception of time and thus may not completely reveal actual time preference. To test this, we explore the causal relationship between time perception and intertemporal choices by conducting a laboratory experiment in which cognitive load is used as a stimulating instrument to induce differences in time perception. We establish that the perceived time lengths for subjects with high cognitive load are shorter than those with low cognitive load and that individuals who underestimate time appear more patient in their intertemporal choices. Mediation analyses show that time perception mediates a significant portion of cognitive load’s effect on intertemporal choices. Our study thus demonstrates that time preference identified by intertemporal choices might be confounded by potentially biased time perception, calling for improving suboptimal time-related economic decisions due to an individual’s misperception of how time flies.

A Qualitative Research Survey on Cardiologist's Ethical Stance in Cases of Moral Dilemmas in Cardiology Clinics.

This study sought to determine cardiologists' degrees of ethical awareness and preferred courses of action for ethical dilemmas frequently encountered in clinical settings. For this evaluation, an online survey was created and sent to cardiologists affiliated with various academic posts in Ankara, Turkey. The survey included ten cases with various ethical considerations selected from our book, "Clinic Ethics with Cases from Cardiology." Four possible action choices were defined for each case. Participants were asked to choose one or more of these preferences. In addition, a fictional change was made in each case's context without changing the original ethical issue, and participants were asked whether an attitude different from the first chosen one was preferred. The participation ratio was 49/185 (26%), consent ratio 47/185 (25,4%), and completion ratio 44/185 (23,7%). Nine of the ten scenario changes did not change participants' preferred action. For most questions, action preferences were concentrated between the two options. Although legal regulations did not reduce ethical dilemmas, they clarified physicians' action preferences. Similarly, as an obscure moral issue gained prominence, physicians were forced to draw clearer lines in their actions. External factors such as healthcare emergencies can change physicians' ethical dilemma-solving attitudes.

Contracting over persistent information

We consider a dynamic principal‐agent problem, where the sole instrument the principal has to incentivize the agent is the disclosure of information. The principal aims at maximizing the (discounted) number of times the agent chooses the principal's preferred action. We show that there exists an optimal policy, where the principal recommends its most preferred action and discloses information as a reward in the next period, until either this action becomes statically optimal for the agent or the agent perfectly learns the state.

Dinâmica Política da Formulação da Política de Acesso à Informação no Brasil

Abstract Freedom of information (FOI) policymaking in Brazil is portrayed as a “successful story.” Data on adherence of the Brazilian legislation to international standards indicates its FOI institutions are in the top-ten group in the substantive dimension of FOI but are the last when it comes to the procedural dimension. What mechanism has driven this process to produce such ambivalence? This study assumes that FOI policymaking in Brazil represented an ambiguous legitimacy-based emulation process, oriented toward homogenization to the international field, but without breaking the governmental control over information. It draws on theoretical work on policy diffusion focusing on emulation and uses theories on conflicts and negotiation for power as drivers of policymaking. The results suggest this process was forged by political dynamics of disputes and compromises, and its outcomes derived from political trade-offs between key actors on controversial issues. Thus, the results materialized the preferences of non-governmental actors for a larger scope and no “eternal secrecy” and assured government offices’ prerogatives on implementation and their final decision on appeals. This case may represent a broader phenomenon, considering that comparative data indicates that this ambivalence in adherence between substantive and procedural dimensions is more significant in Latin America than in other regions.

A Comprehensive Reliability Strategy for Managing Assets of Redundant Customer Delivery Systems

A reliability strategy was developed in 2020 for the purpose of improving the reliability of the dual element spot network (DESN) stations. The strategy utilized the transmission outage data system (TODS) data-base and some reliability models to identify DESN stations with the worst reliability performance so that investment dollars can be directed towards the reliability improvement of those stations. Recently, a comprehensive reliability strategy has been developed to do a similar task of improving the overall reliability of the DESN stations. The new strategy first maps the delivery point interruption data to the TODS outage data to determine the frequencies of the main causes of supply interruptions to delivery points. Then, it identifies action plans (or remedial actions) that are needed in order to reduce the frequencies of the dominant outage causes. Finally, the strategy uses a benefit/cost analysis to select the preferred action plans in order to improve the overall reliability of the DESN stations. The new strategy is more practical and has numerous advantages over the existing one. The purpose of this paper is to describe the new reliability strategy, its advantages over the existing one and to show how to apply it in the DESN stations.

Optimized Development of Hohhot’s New Public Cultural Space Layout Construction Based on Genetic Algorithm under the Perspective of Urban Renewal

Abstract The rational layout and scientific configuration of public cultural space is an important criterion to measure the public service function of a city, whether it is perfect or not. In this paper, Hohhot Downtown is selected as the research object, and the spatial layout structure of the city is explored using the indicators of expansion intensity, compactness and fractal dimension. A layout optimization method based on a genetic algorithm is proposed to build a spatial layout model, set the spatial layout optimization constraints, complete the genetic algorithm optimization through the optimization coding process, and finally solve the Pareto optimization solution set by using the genetic algorithm of Matlab, which results in the optimization scheme of the new public cultural spatial layout of Hohhot City. The results show that six new public cultural space layout schemes of Hohhot are obtained after optimization, and the six layout scores are in the interval of [0.9, 1.0], all of which are excellent. Decision makers can choose the final layout scheme based on their actual situation and decision preferences.

VARIETY OF SHOPPING MODES: THEORETICAL FRAMEWORK, PIVOTAL FACTORS, AND MANAGERIAL IMPLICATIONS

With the development of e-commerce and smartphones, consumers can use a variety of shopping modes (i.e., showrooming, webrooming, and completely offline/online shopping), each of which provides specific advantages in terms of price, assortment, service, etc. Using a great variety of these shopping modes can confer many benefits. However, previous studies have found evidence of sizable segments of consumers who typically avoid using a great variety of shopping modes. To understand the contrast in consumers’ variety of shopping modes, we propose a theoretical framework and measure the effect of the desired variety in the information-seeking and purchase processes. Results – from a representative sample of the Spanish consumers – confirm that the variety of shopping modes pivots on the extent to which e-commerce use, smartphone use, offline and online interactivity, and online device interchangeability differ. Better understanding the variety of shopping modes may help marketers adjust their channel strategies to the actual preferences of different consumer segments and assess the economic viability of an omnichannel approach.

Towards multi-domain user archetypes for user-centred façade design

User experience and satisfaction with the facade play a significant role in user comfort and energy efficiency of buildings. This paper explores the concept of User-Facade archetypes to inform the user-centred design of shading devices based on the perceived level of importance of different environmental domains at the workplace. A questionnaire was developed to collect data on users’ perceived level of importance of different environmental domains, user characteristics and other preferences. Based on the associated level of importance of the domains affected by shading devices (thermal conditions, access to daylight, access to outdoor view, privacy and glare mitigation), users were then clustered into eight different archetypes, which associated different “weights” to each comfort domain. The study also found a significant correlation between the associated level of importance and the reported frequency of interaction with shadings because of thermal comfort, glare mitigation or privacy. Overall, users that associated high levels of importance to several environmental domains also reported high perceived levels of importance for personal control at the workplace. Only one archetype reported low importance for personal control at the workplace. Further work is required to validate these archetypes by capturing actual user behaviour and preferences in real workplaces. However, these findings provide preliminary and valuable insights into the possibility of clustering users on their preferences and using this for informing a more user-centred design or operation of shading devices.
