description: A tax on agricultural greenhouse gas (GHG) emissions has been suggested as a potential means of reducing the GHG emissions associated with agriculture and improving the emissions intensity of production. One of several difficulties in implementing such a tax is the potential uncertainty in emissions estimates. This paper explores this topic using Irish dairy farm production and economic data from the 2015 Teagasc National Farm Survey. On-farm agricultural emissions were estimated by applying the National Inventory Report methodologies at farm level, and the uncertainties in total emissions and emissions per unit of milk produced were demonstrated using a Monte Carlo Simulation approach. The average GHG emissions footprint per kg fat and protein corrected milk (FPCM) was 1.07 kg CO2e with a relatively small uncertainty range of ± 2.59 %. If taxed at a rate of €20 per tonne of CO2e, a typical farm would have to pay €7141 (± 2.25 %), which could have a significant impact on farm incomes, but is not strongly affected by emissions uncertainties. Therefore, although there would remain a number of difficulties in designing an agricultural emissions tax, the level of uncertainty in emissions does not appear to be a significant barrier in this example.

description: There have been a good number of livestock production studies in Kenya at micro-level. However, most of these micro-level analyses have not been able to show the feedback between the livestock sector and the rest of the economy. System dynamics is one of the powerful tools in the field of system thinking which can be used to show this interaction. In order to accomplish these, a series of interviews and workshops was undertaken to identify the problematic situation of smallholder beef farming in West Pokot and Narok Counties. To describe its linkages, this problematic situation was then translated into a causal loop diagram from which the systems archetypes were identified. The nature of each archetype is described, and the implications for identification of the possible system leverage points are discussed. This paper provides a preliminary insight into the application of system thinking in analyzing the small-holder beef production in Kenya.

description: Health Information and Communication Technologies (Health ICT) mediate learning systems in the health sphere, integrating and processing data from multiple sources, in addition to being used as teaching-learning instruments in a series of topics related to health education of synchronously or asynchronously. Considering cancer patients and their caregivers, the deleterious effects of cancer on quality of life, capacity for self-care and doubts that persist from diagnosis and treatment to the scope of home rehabilitation are known. In a similar way, the use of Health ICT is a valuable resource for the continuing education of professionals working in the oncology area. Therefore, the aim is to analyze the scientific evidence about the use of information and communication technology for health education in oncology aimed at patients, family members and the education of health professionals, synthesizing evidence and contributing to care practice. This study describes an integrative review protocol integrated with two other phases of systematic search and a final phase of knowledge synthesis. We propose: 1) a search in PubMed, CINAHL, SCOPUS, LILACS and Web of Science databases with Medical Subject Headings (MeSH), CINAHL subjects, Health Science Descriptors (DeCS), in addition to alternative terms. PRISMA guidelines will be used to check the integrative review report; 2) search for mobile apps on Google Play Store; 3) search for patent registrations at the National Institute of Industrial Property (INPI Brasil) and at PatentScope. Each step will have separate collection and descriptive analysis. Data discussion and presentation will be mediated by the emergence and systematization of common themes and taking into account health education for the patient-caregiver binomial and continuing education for professionals.

description: Various ground-dwelling invertebrates respond differently to changes in the structure of the landscape. Implementation of a mechanistic approach to landscape ecology is essential to deriving generalizations about how spatial heterogeneity influences ecological system. In the study key questions are asked such as, what is the biodiversity of the area? And what are the threats to biodiversity in the area? We aimed to investigate the response of ground-dwelling insects assemblages to Eucalyptus (Bluegum) plantations and Avocado orchards in the western Soutpansberg. We also aimed to develop strategies to maintain, manage and possibly restore the degraded landscapes in the Soutpansberg Mountain using invertebrates as surrogate species to monitor these changes. The study area was Bluegumspoort, the Soutpansberg Limpopo Province, South Africa. Four sites representative of the landscape mosaic where located for the study. The first site located was an Avocado orchard, the second site a Bluegum plantation, third site located was a pristine savanna mist belt and the fourth site a thicket located on Lokovhela. Hand collecting, observations and pitfalls where used to trap and preserve ground-dwelling darkling beetles, (Tenebrionidae), dung beetles (Scarabaeidae), ground beetles (Carabidae) and snout beetles ( Curculionidae) at alternating stretches of diurnal and nocturnal sampling. Tenebrionidae constitute the greatest species richness followed by the Scarabaeidae.

description: Ultra-massive hydrogen-rich (DA spectral type) white dwarf (WD) stars ($M_{\star} > 1M_{\odot}$) coming from single-star evolution are expected to harbor cores made of $^{16}$O and $^{20}$Ne, resulting from semi-degenerate carbon burning when the progenitor star evolves through the super asymptotic giant branch (S-AGB) phase. These stars are expected to be crystallized by the time they reach the ZZ Ceti instability strip ($T_{\rm eff} \sim 12\,500$ K). Theoretical models predict that crystallization leads to a separation of $^{16}$O and $^{20}$Ne in the core of ultra-massive WDs, which impacts their pulsational properties. This property offers a unique opportunity to study the processes of crystallization. Here, we present the first results of a detailed asteroseismic analysis of the best-studied ultra-massive ZZ Ceti star BPM~37093. As a second step, we plan to repeat this analysis using ultra-massive DA WD models with C/O cores in order to study the possibility of elucidating the core chemical composition of BPM~37093 and shed some light on its possible evolutionary origin. We also plan to extend this kind of analyses to other stars observed from the ground and also from space missions like Kepler and TESS.

description: The Base of the Pyramid (BoP) consumers living in the urban informal settlement of developing countries spend over 60% of their income on food, yet malnutrition and micronutrient deficiency remains widespread among this population, pointing to the inadequacy of the foods they consume in terms of quality and quantity. In this paper we examine BoP consumer willingness to pay (WTP) for safe and nutritious multicomposite porridge flour (improved flour) in the informal settlements of Nairobi, Kenya and Kampala, Uganda. In 2016, we collected primary data from 600 consumers in the informal settlements of Kampala, Uganda and Nairobi, Kenya (300 in Kenya and 300 in Uganda). We use Tobit regression models to analyse determinants of WTP for the improved flour. Results show that both Kenyan and Ugandan consumers are willing to pay a premium for the improved flour. In addition, providing nutrition information of the flour, characteristics of household head, economic status of the household, and presence of young children between 6 and 59 months in the household influence WTP for the safe and nutritious porridge flour. The paper concludes by providing recommendations for enhancing nutrition among poor consumers in the informal settlements of developing countries.

description: When aspects of quality are unobservable in the market, returns to quality will be low and producers will lack incentives to invest in quality. In the case of food safety, this can have significant implications for health, as with the example of aflatoxin, a toxin produced by a fungus commonly found on maize and groundnut. We show that Kenyan farmers who produce maize for sale are less likely to undertake postharvest practices that increase the unobservable quality of aflatoxin safety, as compared to farmers who produce maize only for their own family’s consumption. Employing randomized discount vouchers, we find that willingness to pay for a new post-harvest technology to prevent aflatoxin contamination in maize is significantly lower among market producers than subsistence farmers. However, we find that take-up of the technology among market producers is increased by an opportunity to sell aflatoxin-safe maize at a premium a few months after harvest. This suggests that testing-based market incentives could address the underinvestment in unobservable quality in agriculture. However, widespread testing, if not accompanied by technologies to significantly reduce aflatoxin prevalence, could result in increased consumption of aflatoxin-contaminated maize by the poorest members of society.

description: Climate change is a threat to food security in Africa. Maize is the most important staple crop in Kenya, but production per capita has decreased in recent decades. Climate smart agriculture technologies become more important, but it is important to evaluate them with farmers to learn about their needs. Therefore, we conducted participatory evaluations of five miaze varieties both on-farm and on-station. We found that farmers’ perception of varieties are complex, with yield, drought tolerance, and early maturing valued the most. Men value characteristics related to size higher than women (cob size, stalk thickness). On average, men give higher scores than women, and women score more nuanced. On-station, DH02 was liked the best, and Tego the least. On-farm, DH02 was liked the least, while Duma43 was liked the most. Further, onfarm, DH02 was liked less in the wet year than in the dry year. Farmers’ scores did not reflect yield data well, indicating their complex perceptions of varieties. Further, farmers in Makueni could increase their annual income by 51.500 KSh by adopting the improved maize varieties from this study. Maize companies could benefit from an increase in sales, with a potential demand in Makueni of 3.500 metric tons per season.

description: Purposes : To investigate income mobility of farm households with land-expropriated in the process of urbanization in China, and explore factors affecting income mobility. Methods: Data derives from a project financially supported by Natural Science Foundation of China in 2013. Using principles of stratified random sampling, 429 farm households are selected. Data: income; endowments; demographic; schemes in supporting land expropriation; risk factors. We use Income Transition Matrix to investigate income mobility, and Ordinal Logistic Regression to explore its determinants. Conclusions: 1) Income mobility has different changing patterns after land expropriation. 2) Working capitals, including land, level of labor force s education and social relations, are linked to income mobility changes. Capital accumulation is important. 3) Households in lower/medium income groups are more likely to flow downward when they have: lower level of education, or weak social capital, or larger land expropriation, or member suffering health risk, or not participate in government "Land for Social Security" scheme. 4) Types of risk are closely associated with income downward flow. Interventions should target at strengthening household working capitals, especially human capital, and at preventing them from suffering risks, and at reforming "Land for Social Security" scheme to support sustainable livelihoods. Key words: Income Mobility, Land expropriation, Farm Households, Capitals, Risks Acknowledgement : Funding for data collection has been provided by the National Natural Science Foundation of China (grant number:71173239).

description: In the context of an upcoming CAP-reform which will most likely condition payments to farmers stronger on a measurable provision of public goods, the aim of this study is to elicit the willingness to pay (WTP) for public goods (PGs) provided by agriculture in the Marchfeld, a dynamically developing and semi-urban region in Austria. Situated between Vienna and Bratislava it is marked by an intensive agricultural production and at the same time rising environmental awareness of the local population. We carry out a discrete choice experiment for the 3 public goods ground water quality, landscape diversity and climate stability, which were pre-selected via focus groups. Due to high preference heterogeneity we estimate a random parameters logit model and include interactions with socio-demographic factors in order to further disentangle differences in preferences. We find a positive and significant WTP for all three public goods, with groundwater quality being most important for the participants, followed by landscape diversity and climate stability. The results of this study in combination with a supply-side assessment, consisting of different management options for farmers, could form the basis for the development of governance mechanisms for the smart provision of public goods by agriculture in the Marchfeld region.

Policy Recommendations of Carbon Footprints Reduction for AMS Supply Chain : Replacing Products with High Agricultural Emissions

description: The UBC AMS is a large community that offers a variety of services to UBC students and employees. While it caters for the whole campus, a huge amount of carbon emissions are also generated in the supply chain. We are concerned about this because greenhouse gasses may have an influence on climate changes and the environment. Among all the stages in the supply chain, agricultural production is the one that has been found to be the major source of emissions. Hence, to help AMS build a eco-friendlier supply chain, we consider replacing products that are high in agricultural emissions by their alternatives. To do so, we conducted an audit on AMS’ products and calculated their total carbon footprints. We then regressed the total carbon footprints on food types, controlling for distances, weights, and packaging materials. This would allow us to estimate the agricultural impact of each product. Based on the results, we found coffee and dairy are two types that have high agricultural emissions. Consequently, we recommended replacing those by tea and vegan milk, respectively. Moreover, we have also proposed a supplementary plan to further reduce the emission, that is, replacing white chocolate with dark chocolate. For each of the three pairs mentioned above, we stimulated the reductions in overall emissions when substituting different proportions of the high-emission types (i.e. 15%, 20%, and 25% for coffee and dairy; 30%, 40%, 50% for white chocolate), so that AMS can choose the plan that best suits their needs. Although there are still some limitations such as insufficient data and omitted variables, our findings are robust to different assumptions and specifications. We hope that while AMS is balancing between the demand and supply of their foods, our research can shed some light on possible ways to lower their emissions.

description: We demonstrate that a Josephson junction with a half-metallic weak link integrated into the superconducting loop enables the pumping of magnetic flux piercing the loop. In such junctions, the ground state phase $ψ$ is determined by the mutual orientation of magnetic moments in two ferromagnets surrounding the half-metal. Thus, the precession of magnetic moment in one of two ferromagnets controlled, e.g., by the microwave radiation, results in the accumulation of the phase $ψ$ and subsequent switching between the states with different vorticities. The proposed flux pumping mechanism does not require the application of voltage or external magnetic field which enables the design of electrically decoupled memory cells in superconducting spintronics.

In the first stage, linear least squares is used to obtain a subset of the unknown parameters (set 1), while a residual sampling procedure is used for selecting initial values for the rest of the parameters (set 2). In the second stage, depending on the uniqueness of the local minimum, either only the parameters in the second set need to be re-estimated, or all the parameters will have to be re-estimated simultaneously, by a nonlinear constrained optimization. The estimates from the first stage are used as initial conditions for the second stage optimizer. It is shown that this approach alleviates the sensitivity to initial conditions and minimizes the likelihood of converging to an incorrect local minimum of the nonlinear cost function. An error bound analysis is presented to show that the first stage can be solved in such a way that the total cost function will be driven to the optimal cost, and the difference has an upper bound. Two tutorial examples are used to show how to implement this estimator and compare its performance to other similar nonlinear estimators. Finally, the estimator is used on a 5-hole Pitot tube calibration problem using flight test data collected from a small Unmanned Aerial Vehicle (UAV) which cannot be easily solved with single-stage methods.

description: Internet of things (IoT) is powering up smart cities by connecting all kinds of electronic devices. The power supply problem of IoT devices constitutes a major challenge in current IoT development, due to the poor battery endurance as well as the troublesome cable deployment. The wireless power transfer (WPT) technology has recently emerged as a promising solution. Yet, existing WPT advances cannot support free and mobile charging like Wi-Fi communications. To this end, the concept of mobile energy transfer (MET) is proposed, which relies critically on an resonant beam charging (RBC) technology. The adaptive (A) RBC technology builds on RBC, but aims at improving the charging efficiency by charging devices at device preferred current and voltage levels adaptively. A mobile ARBC scheme is developed relying on an adaptive source power control. Extensive numerical simulations using a 1,000mAh Li-ion battery show that the mobile ARBC outperforms simple charging schemes such as the constant power charging, the profile-adaptive charging, and the distance-adaptive charging in saving energy.

description: Informed by the boundary of the firm, this paper explains the concepts, determinants and importance of boundary in cooperative organizations. In a marketing cooperative context, we define boundary as the type and number of marketing activities or services that a cooperative organization provides to its members. Using a mix of theory from transaction cost economics, industrial organization and collective actions, the conceptual analysis predicts the importance of the type of goods (being a club good or not) the cooperatives generate to their members, as opposed to market imperfection per se, to define a competitive boundary. We then empirically tested if the observed weak performance of marketing cooperatives in Africa is explained by the strategic failure of engaging in markets where they do not have the competitive and comparative advantages using a unique data set from Ethiopia. The empirical tests proofed that the competitiveness of a cooperative in attracting and committing its members is positively and significantly related to the likelihood of a cooperative providing a club good. However, significant number of cooperatives in Ethiopia engaged in services for which the markets are not convincingly imperfect. Furthermore, they participate in markets that generate public goods rather than club goods. Acknowledgement :
Toward a Background Independent Quantum Theory of Gravity

description: Any canonical quantum theory can be understood to arise from the compatibility of the statistical geometry of distinguishable observations with the canonical Poisson structure of Hamiltonian dynamics. This geometric perspective offers a novel, background independent non-perturbative formulation of quantum gravity. We invoke a quantum version of the equivalence principle, which requires both the statistical and symplectic geometries of canonical quantum theory to be fully dynamical quantities. Our approach sheds new light on such basic issues of quantum gravity as the nature of observables, the problem of time, and the physics of the vacuum. In particular, the observed numerical smallness of the cosmological constant can be rationalized in this approach.

description: The spread of plants from one country to another through intentional and unintentional human activities is a serious threat to the world’s biodiversity; second only to habitat destruction. However, a number of studies have shown that invasive alien plant species can positively contribute to rural economies. This paper is an attempt to document a few of these species ‘positive contribution to rural inhabitants’ well-being in and around Thulamela Local Municipality in Vhembe District of South Africa. Information on the uses of invasive alien plant species were obtained in 2010 through interviews with local inhabitants and traditional healers. Twenty one plant species, from 15 families, were found to be utilized by rural inhabitants. These species are important sources of food and medicine, provide firewood, and are of aesthetic value. They have become alternative sources of utilization, where the indigenous vegetation has been decimated by overexploitation. This study postulates that their extensive use, under careful management, could form part of a strategy for social upliftment and environmental management in poor rural municipalities.

description: Abstract This study examines the economic feasibility of improved storages and the potential impacts of using them on household food security and income. Moreover, it tests whether storage losses can induce early sale of households maize produce. We used data from on-farm experiment, household survey, and secondary sources. We considered Purdue Improved Crop Storage (PICS) bags, metallic silos, and polypropylene bags (control). Results show that PICS bags are profitable when the grain is sold during the lean season. However, the economic feasibility of metallic silos depends on the size of the storages and location i.e. silos of 1.5t and 2t storage capacities are feasible in some districts while lower size silos are not feasible in all locations. Storing maize using PICS bags will enhance household food security, especially among net-buyer farm households enabling them to reduce their annual grain deficit period by three to four weeks. Moreover, market-oriented storage using the improved storage options can increase farmers income substantially. Our results do not justify that the sell low, buy high situation observed among smallholder farmers is caused by high grain losses due to storage insect pests.

description: Although new production technologies are often regarded as one of the key drivers of the reduction in live birth per women, empirical evidence is scarce. This paper addresses this gap, exploring the expansion of oil palm in Indonesia. We argue that this type of technological change is rather unique, as it induces gender-specific labor savings that affect not only large-scale farms but also smallholder farmers. We use Becker s quantity-quality model to identify different causal mechanism through which the expansion of oil palm could affect fertility rates. Our identification strategy relies on an instrumental variables approach with regency-fixed effects, in which the expansion of area under oil palm at regency level is instrumented by regency-level attainable yield of oil palm interacted with the national oil palm expansion. We find consistently negative effects of the oil palm expansion on fertility. The results suggest that the negative effect is mainly explained by increasing female wages and increasing consumption expenditure. This suggests that the fertility reduction was driven by income effects of the oil palm boom at the household level, as well increased female opportunity costs of child rearing.
