The purpose of this study was to examine the impact of situation and outlook information from World Agricultural Supply and Demand Estimates (WASDE) in corn and soybean futures markets over the period 1985 to 2006. Results indicate that WASDE reports containing National Agricultural Statistics Service (NASS) crop production estimates and other domestic and international situation and outlook information have the largest impact; causing return variance on report sessions to be 7.38 times greater than normal return variance in corn futures and 6.87 times greater than normal return variance in soybean futures. WASDE reports limited to international situation information and domestic and international outlook information have a smaller impact. The results show that the impact of WASDE reports has increased over time.

AbstractPurpose: Some universal accessibility practitioners have voiced that they experience a mismatch in the research focus and the need for knowledge within specialized problem domains. This study thus set out to identify the balance of research into the main areas of accessibility, the impact of this research, and how the research profile varies over time and across geographical regions. Method: All UAIS papers indexed in Scopus were analysed using bibliometric methods. The WCAG taxonomy of accessibility was used for the analysis, namely perceivable, operable, and understandable. Results: The results confirm the expectation that research into visual impairment has received more attention than papers addressing operable and understandable. Although papers focussing on understandable made up the smallest group, papers in this group attracted more citations. Funded research attracted fewer citations than research without funding. The breakdown of research efforts appears consistent over time and across different geographical regions. Researchers in Europe and North America have been active throughout the last two decades, while Southeast Asia, Latin America, and Middle East became active in during the last five years. There is also seemingly a growing trend of out-of-scope papers. Conclusions: Based on the findings, several recommendations are proposed to the UAIS editorial board.

The Impact

The primary goal of this article is to evaluate water scarcity in selected countries of the Middle-East and assess the impact on agricultural production. To begin with, the Weighted Anomaly Standardized Precipitation (WASP) Index from 1979 to 2017 was spatially computed for Iran, Iraq and Saudi Arabia. In order to demonstrate the effect of reduced levels of water, the water shortage situation in cities with the population higher than one million was examined. This was accomplished by utilizing the Composite Index approach to make water related statistics more intelligible. A projection for the years of 2020 to 2030 was created in order to demonstrate possible changes in the supply and demand for water in selected countries of the Middle-East. In regards to evaluating the economic effects of water shortages on agricultural sector, effects of lower precipitation on agricultural production in Iran, Iraq and Saudi Arabia were estimated. With ever-increasing urbanization, all countries are currently experiencing a moderate to high water risk. Our research points to excessively high water stress for most analyzed cities through the year 2030. Also, it is demonstrated how much precipitation decreases influence agricultural production in Iran, Iraq and Saudi Arabia. From the analyzed countries, some evidence is found that precipitation negatively influences crop production, primarily for Iran.

Consumption Curve

Nutrition has an important relationship with health and illness. One difficulty in measuring intake is related to variability. The purpose of this paper is to examine 1) the impact of supply and demand on variability in data collected for dietary studies and 2) the relationship between data and estimates of usual intake. The forces of supply and demand over time generate a consumption curve for each food. Two types of consumption curves are identified. One curve is horizontal and represents staples that are steadily consumed. The other curve exhibits peaks and dips and is unique for each food whose consumption varies with time. The measurement of usual intake is discussed in. light of these two types of curves. Usual intake of foods whose consumption curve is horizontal could be read at any time since consumption does not vary with time. For all other foods, measuring usual consumption presents problems since the data vary with time. This examination indicates that foods whose consumption varies with time have unique properties that must be considered when attempting to calculate consumption. Suggestions are given to enhance measurement of consumption of these foods. Although excellent methodology currently exists for the calculation of intake, attention to the force of supply and demand with only serve to strengthen existing methods.

Despite the widespread adoption of shuttle train grain elevators and their potential for reducing rates for grain transport, few studies have evaluated their impact on railroad pricing. The aim of this paper is to assess railroad pricing behavior as well as empirically examine the impact of shuttle train movement on hard red spring wheat transport from North Dakota over time. Ordinary least squares estimation of the pricing model has rate per ton-mile as a dependent variable and supply and demand determinants as regressors. Intermodal competition and shuttle trains were found to have played a significant role in rate reduction over time.

Nepal’s economy is largely based on agriculture, predominantly small-scale farming, and about half of which is dependent on natural rainfall. In Nepal, agriculture is a highly climate sensitive sector. Historically, the sector has been affected by floods, droughts and erratic rainfall. This study focused on the impacts and economic costs of climate change in agriculture and assessed perceptions of communities of Kaski and Mustang districts on frequency and intensity of hailstorm events over time including their related impacts. Scenario-based impact assessment was used for assessment of long-term impacts and economic costs of climate change. The study used Decision Support System for Agro-technology Transfer (DSSAT) model to analyze the effects of climate on three major crops, namely rice, maize and wheat. The economic loss due to the impacts of climate change in cereals (rice, maize and wheat) was estimated at around US$ 336.42 million in the year 2006. Among the respondents, 60% reported food shortages which made them highly vulnerable due to climate variability. Similarly, 80% of the respondents mentioned that 20 major hailstorm events have occurred in the vicinity of their communities over the last 35 years (up to 2012) and have caused significant damage to crop production, livestock and infrastructure. DesInventar database reported damage of 75% to 100% of the key crops. Crop yield projections indicate a complex mix of increases and decreases in yield which vary over time (in projections in 2030 AD and 2070 AD) and by location (east to west/Terai to Mountains). In the 2030s, there is a net increase in production and values; however, by the 2070s, the impact in agricultural production is expected to reach to US$ 140 million/year (2014). In terms of research, there are priorities around further work to understand climate uncertainty, the indirect economic costs of these impacts, and early research priorities to address long-term challenges. There is an urgent need to build capacity, with information and awareness raising, monitoring, research, and institutional strengthening.

Background: A substantial proportion of therapists experience the loss of a patient to suicide at some point during their professional life. Aims: To assess (1) the impact of a patient’s suicide on therapists distress and well-being over time, (2) which factors contribute to the reaction, and (3) which subgroup might need special interventions in the aftermath of suicide. Methods: A 63-item questionnaire was sent to all 185 Psychiatric Clinics at General Hospitals in Germany. The emotional reaction of therapists to patient’s suicide was measured immediately, after 2 weeks, and after 6 months. Results: Three out of ten therapists suffer from severe distress after a patients’ suicide. The item “overall distress” immediately after the suicide predicts emotional reactions and changes in behavior. The emotional responses immediately after the suicide explained 43.5% of the variance of total distress in a regression analysis. Limitations: The retrospective nature of the study is its primary limitation. Conclusions: Our data suggest that identifying the severely distressed subgroup could be done using a visual analog scale for overall distress. As a consequence, more specific and intensified help could be provided to these professionals.

This paper has a two-fold objective: first, to examine the terms on which Pakistan receives aid and whether its debt situation is sustainable, and second, to examine the impact of aid and debt on economic growth. It is found that there is little encouraging that can be said about how the terms on which Pakistan has received aid over time have changed, and its current debt situation is not sustainable. Also reported is the analysis done elsewhere which shows that aid has a negative (Granger) causal impact on GDP, and aid has a robust negative impact on economic growth after controlling for supplyside shocks. We provide various reasons for this negative association.

The Impact

This paper attempts to study the Nigerian agriculture industry as a panacea to growth as well as an anchor to the diversification agenda of the present government. To do this, the time series data of the four agriculture subsectors of crop production, livestock, forestry and fishery were analysed as stimulus to the Real GDP from 1981-2016 in order to explicate the individual contributions of the subsectors to the RGDP in order to guide the policy thrust on diversification. Using the Johansen approach to cointegration, all the variables were found to be cointegrated. With the exception of the forestry subsector, all the three subsectors were seen to have impacted on the real GDP at varying degrees during the time under review. The crop production subsector has the highest impact, however, taking size-by-size analysis, the livestock subsector could be of much importance due to its ability to retain its value chain and high investment returns particularly in poultry. Therefore, it is recommended that, the government should intensify efforts to retain the value chain in the crop production subsector, in order to harness its potentials optimally through the encouragement of the establishment of agriculture cottage industries. Secondly, the livestock subsector is found to be the most rapidly growing and commercialized subsector. Therefore, it should be the prime subsector to hinge the diversification agenda naturally. Lastly, the tourism industry which is a source through which the impact of the subsector is channeled to the GDP should be developed, in order to improve the impact of such channel to GDP with the sole objective to resuscitate the forestry subsector.
