However, there is limited scholarly evidence and explanation that has been conducted on the factors that influence the choice of alternative sets of strategies that smallholder farmers use in response to climate variability specific stress and literature that disentangles climatic stressors specific adaptation options. A multi-stage sampling procedure was employed to select the study area and household respondents. The study used cross-sectional research design to collect both quantitative and qualitative data. Household data was collected from 160 respondents with a structured questionnaire supported by key informant interviews. Multinomial logit modeling (MNL) was used to determine the relative influence of selected household socio-demographic factors on the choice of adaptation strategies against the dry spell. Principal Components Analysis (PCA) was used to create weighted adaptation index for categorizing various similar adaptation strategies. In order to respond to the impact of climate variability stresses, smallholder farmers have adapted growing drought-resistant crops (12.2%), extension of the agricultural frontier into wetlands during the dry spells (37%), whereas use of crop rotation (9.8%) is the most dominant strategies used to manage pest and diseases, similarly soil and water conservation (15.3%) and climate-smart planning basin (11%) are the most dominant adaptation strategies use to manage flood. Empirical results from multinomial logit modeling showed that predictor variables gender, level of education, years of farming, house size, access to credit, and own radio have a significant influence on the choice of adaptation strategies with differences significant level during the dry spell. The study recommends that future policies should focus on strengthening the existing extension training package, strengthening the existing farmer’s groups and cooperatives, encouraging informal social networks in order to boost smallholder farmers’ adaptation to climate variability.展开更多

We consider a derivative and inverse free method for the imple- mentation of Lavrentiev regularization method. Using general HSlder type source condition we obtain an optimal order error estimate. Also we consider the adaptive parameter choice strategy proposed by Pereverzev and Schock （2005） for choosing the regularization parameter.展开更多

But there are certain type of perfect information games （PI-games）, the so-called positional game or Banach-Mazur games, which so far have not been applied in economy. The perfect information positional game is defined as the game during which at any time the choice is made by one of the players who is acquainted with the previous decision of his opponent. The game is run on a sequential basis. The aim of this paper is to discuss selected Banach-Mazur games and to present some applications of positional game. This paper also shows new theoretical example of a determined PI-game, based by theoretical overview. All considerations are pure theoretical and based by logical deduction.展开更多
