The ultimate objective of the problem under study is to apply the min-max tool, thus making it possible to optimize the default risks linked to several areas: the agricultural sector, for example, which requires the optimization of the default risk using the following elements: silage crops, annual consumption requirements, and crops produced for a given year. To minimize the default risk in the future, we start, in the first step, by forecasting the total budget of agriculture investment for the next 20 years, then distribute this budget efficiently between the irrigation and construction of silos. To do this, Bangladesh was chosen as an empirical case study given the availability of its data on the FAO website; it is considered a large agricultural country in South Asia. In this article, we give a detailed and original in-depth study of the agricultural planning model through a calculating algorithm suggested to be coded on the R software thereafter. Our approach is based on an original statistical modeling using nonparametric statistics and considering an example of a simulation involving agricultural data from the country of Bangladesh. We also consider a new pollution model, which leads to a vector optimization problem. Graphs illustrate our quantitative analysis.

State Of Affairs

Today most foreign aid donors are genuinely committed to the idea that development in Third World countries should start with rural development. Therefore, a sizable proportion of their development funds are invested in rural projects. However, donors channel these funds through local governments (most often representing local bourgeois interests) that are not as committed to the principle of rural development. These governments are often also embarked in policies that are actually—directly or indirectly—expropriating the surpluses generated by agriculture and investing them in the other sectors of the economy. The peasants are therefore footing most of the bill of overall national development. This paper contends that, because of this state of affairs, foreign aid directed toward rural development is actually filling the investment gap left by an internal system of unequal returns to production in agriculture. In so doing, foreign aid is indirectly financing the development of the other sectors of the economy, even if this result is unintended. This perpetrates maldevelopment without redressing the basic exploitation process of peasants which lies at the core of underdevelopment. Evidence to support this hypothesis is presented using data from a primarily agricultural exporting country: the United Republic of Cameroon.

This study provides a model that supports systematic stakeholder inclusion in agricultural technology. Building on the Responsible Research and Innovation (RRI) literature and attempting to add precision to the conversation around inclusion in technology design and governance, this study develops a framework for determining which stakeholder groups to engage in RRI processes. We developed the model using a specific industry case study: identifying the relevant stakeholders in the Canadian digital agriculture ecosystem. The study uses literature and news article analysis to map stakeholders in the Canadian digital agricultural sector as a test case for the model. The study proposes a systematic framework which categorises stakeholders into individuals, industrial and societal groups with both direct engagement and supportive roles in digital agriculture. These groups are then plotted against three levels of impact or power in the agri-food system: micro, meso and macro.

Clarke Subdifferentials

In this paper, K- quasiconvex, K- pseudoconvex and other related functions have been introduced in terms of their Clarke subdifferentials, where   is an arbitrary closed convex, pointed cone with nonempty interior. The (strict, weakly) -pseudomonotonicity, (strict) K- naturally quasimonotonicity and K- quasimonotonicity of Clarke subdifferential maps have also been defined. Further, we introduce Minty weak (MVVIP) and Stampacchia weak (SVVIP) vector variational inequalities over arbitrary cones. Under regularity assumption, we have proved that a weak minimum solution of vector optimization problem (VOP) is a solution of (SVVIP) and under the condition of K- pseudoconvexity we have obtained the converse for MVVIP (SVVIP). In the end we study the interrelations between these with the help of strict K-naturally quasimonotonicity of Clarke subdifferential map.

Abstract In our paper we will continue the comparison which was started by Vsevolod I. Ivanov [Nonlinear Analysis 125 (2015), 270–289], where he compared scalar optimality conditions stated in terms of Hadamard derivatives for arbitrary functions and those which was stated for ℓ-stable functions in terms of Dini derivatives. We will study the vector optimization problem and we show that also in this case the optimality condition stated in terms of Hadamard derivatives is more advantageous.

Purposive Sample

This study aimed to highlight the challenge that Secondary School teachers face in integrating the Islamic concept of tawhid in teaching science and history subjects. The research employed a qualitative design using a case study and collect data. A purposive sample consisting of 5 teachers from Al-Amin Islamic Secondary School was selected based on teaching experience. The teachers were interviewed according to a theme-based strategy, and collected data was transcribed and analyzed accordingly. Findings have shown that integrating tawhid in the subjects of Science and History is an aim that teachers in Islamic schools in Malaysia hope to achieve. However, obstacles and challenges continue to hinder their efforts. Theoretical and practical propositions and recommendations to make this aim achievable, such as revisiting the concept of tawhid integration, enhancing teachers' creativity skills in the classroom, and providing relevant training programs by school authorities, would undoubtedly help attain their ultimate objective.

This study is carried out in Delanggu, Klaten, that has high productivity of rice but undergoing a decrease in the role of the sector of agriculture. The goal of this study is to observe young people departicipation in the sector od agriculture and fators that influence it. The method used is survey method. The population is all of the young people in Delanggu, 1.419 peoples. The sampling uses stratified proporsional quota sampling where respondents are divided into three groups of age, 15-19 years old, 20-24 years old, and 25-29 years old. Every sampling in eah group is taken 5% proportionally, with its homogenates consideration, while the characteristic, which has determined in order to fulfil the number of determined quota in each age group. Collected data is presented in the form of frequency and cross table. Qualitative data analysis uses logical thought, deducyive-inductive, analogy ang comparison, whereas analyzing frequency and cross table uses quantitative data analysis. The use of both analysis is adjusted to the data and goal of the study.
