Opis:
The main objective of this paper was to determine the factors that affect the livelihood strategies of resettled smallholder farmers in Zimbabwe. The study was conducted in Manicaland Province in Zimbabwe, and the respondents were stratified into four groups. These were smallholder farmers resettled under the A1 and A2 models, as well as tobacco and non-tobacco smallholder farmers. The two models differ in how they were implemented and supported, which might lead to them having different livelihood strategies. A total of 300 respondents were surveyed, consisting of 114 tobacco and 149 non-tobacco farmers and 24 off-farm and 13 wageearner households in Manicaland province. The study used a Multinomial Logit model to investigate the factors influencing a household’s decision to choose different livelihood strategies. In the model, the dependent variables included four livelihood strategies, while the explanatory variables included various household social-economic and institutional factors. The results obtained from the multinomial logistic regression model established that gender and land size were significant at a level of 1%, and education, household size, access to credit and access to inputs were significant at 5% in the adoption of tobacco farming, access to credit and gender were significant at a 1% level in the adoption of non-tobacco farming, while education was significant at a 10% level in adopting off-farm were found to be significant in determining the adoption of the tobacco farming in the study area up to less than 10% probability level in adopting off-farm activities. Smallholder farmers who did not adopt tobacco farming indicated that limited land size, shortage of labour and access to tobacco inputs were the major impediments to adopting tobacco farming. The government should support the efforts of smallholder farmers to increase their livelihood strategies through unveiling credit lines for farming activities. Access to inputs for smallholder farmers should be made a priority by the government through the provision and fair distribution of adequate agricultural inputs.

Opis:
Binomial logit models are commonly used in the analysis of the situation of respondents on the labour market. Consequently, in most cases researchers consider two states: of being unemployed and employed or economically inactive and active. This paper focuses on the situation of young people aged 18 to 29 on the labour market in Poland. A major part of the people who comprise the studied group are still in education or combine education with work. Therefore, the participants of the research were divided into the following groups: the employed and not learning, those combining education with work, the unemployed, learners/students only, and those economically inactive and not at school. The model allowing an analysis which includes both the most common division into working and nonworking persons as well as the division proposed in this study is a nested logit model. This model has a hierarchical structure and is a special case of a multinomial logit model. In this paper, all models were estimated within the Bayesian approach. The findings show that continuing education by young people may result from their problems with finding a job; moreover, combining work with education is not the preferred form of professional activity. In addition, the study examines the inequalities observed on the Polish labour market.

Opis:
Celem opracowania jest zidentyfikowanie i skwantyfikowanie wpływu czynników determinujących sposób działania wobec wystąpienia problemu prawnego. Na podstawie przeglądu literatury opracowano listę takich czynników, a następnie na podstawie danych pochodzących z ogólnopolskiego badania ankietowego przeprowadzonego w 2012 r. przez Instytut Spraw Publicznych (ISP) w Warszawie oszacowano parametry strukturalne wielomianowego modelu logitowego. Z badania wynika, że decyzja co do sposobu postępowania prawnego zależy przede wszystkim od rodzaju doświadczanego problemu, jego rangi, postaw wobec prawa oraz kilku innych cech socjoekonomicznych dotkniętych nim osób. Wyniki badania pokazują również, że ograniczenia popytu na usługi poradnictwa prawnego z tytułu niskich dochodów nie są znaczące, ważniejszą barierą jest natomiast przestrzenna dostępność usług poradniczych.
The aim of the study is to identify and quantify the influence of factors determining the reaction to the occurrence of a legal problem. On the basis of literature review, a list of such factors was prepared and, subsequently, on the basis of data from the national survey conducted by the Institute of Public Affairs (IPA) in Warsaw in 2012, structural parameters of the multinomial logit model were estimated. The research presents that a decision on the legal problem depends primarily on the type of experienced issue, its importance, attitudes towards law and several other socio-economic features which influenced people. Moreover, the research outcomes show that reductions in demand for legal counselling caused by the low income are not significant, whereas, spatial availability appears to be a more important barrier.

Opis:
The behavioral features of the population are addressed in transport models by different levels of territorial disaggregation and the creation of demand strata in a territory. The need for input data grows exponentially with the demand for a detailed zonal system of the territory. The basic source is the mobility survey. This article deals with the comparison of the calculation of the probability of choosing a transport mode for trips using the classic multinominal logit model and the best-worst method. We used data from a mobility survey in the Žilina region as a basic sample. The analysis covered 11 districts and their gravity areas. The individual transport relations are evaluated in detail in the analysis. The results confirm the high degree of accuracy of the best-worst method in the calculation of mode choice on a regional scale. Despite the promising results of the agreement in the confrontation with the mobility survey, it is necessary to verify the modeled data with a more detailed area with disaggregation on-demand strata.

Opis:
Travel Demand Management (TDM) can be considered as the most viable option to manage the increasing traffic demand by controlling excessive usage of personalized vehicles. TDM provides expanded options to manage existing travel demand by redistributing the demand rather than increasing the supply. To analyze the impact of TDM measures, the existing travel demand of the area should be identified. In order to get quantitative information on the travel demand and the performance of different alternatives or choices of the available transportation system, travel demand model has to be developed. This concept is more useful in developing countries like India, which have limited resources and increasing demands. Transport related issues such as congestion, low service levels and lack of efficient public transportation compels commuters to shift their travel modes to private transport, resulting in unbalanced modal splits. The present study explores the potential to implement travel demand management measures at Kazhakoottam, an IT business hub cum residential area of Thiruvananthapuram city, a medium sized city in India. Travel demand growth at Kazhakoottam is a matter of concern because the traffic is highly concentrated in this area and facility expansion costs are pretty high. A sequential four-stage travel demand model was developed based on a total of 1416 individual household questionnaire responses using the macro simulation software CUBE. Trip generation models were developed using linear regression and mode split was modelled as multinomial logit model in SPSS. The base year traffic flows were estimated and validated with field data. The developed model was then used for improving the road network conditions by suggesting short-term TDM measures. Three TDM scenarios viz; integrating public transit system with feeder mode, carpooling and reducing the distance of bus stops from zone centroids were analysed. The results indicated an increase in public transit ridership and considerable modal shift from private to public/shared transit.

Opis:
Mode choice analysis of school trips becomes important due to the fact that these trips contribute to the second largest share of peak hour traffic. This scenario is more relevant in India, which has almost 265 million students enrolled in different accredited urban and rural schools of India, from Class I to XII as per the UDISE report of 2019-20. Thus, it becomes necessary to understand what mode of transport will be mostly used for school trips in order to design an efficient transportation system. Modal attributes and socio-economic characteristics are mostly considered as explanatory variables in travel mode choice models. Multinomial Logit (MNL) model is one of the classic models used in the development of mode choice models. These logistic regression models predict outcomes based on a set of independent variables. With the recent advances in machine learning, transportation problems are getting a wide arena of methods and solutions. Among them the method of ensemble learning is finding a prominent place in contemporary modelling. This study explores the potential of using ensembles of random decision trees in mode choice analysis by Random Forest Technique with a comparative analysis on conventional method. It was observed that Random Forest method outperforms MNL method in predicting the mode choice preference of students. The high accuracy of machine learning models is mainly due to its ability to consider complex nonlinear relationship between socio-economic attributes and travel mode choice. These models can learn and identify pattern characteristics extracted from sample data and form adaptive structures through computational process thereby offering insights into the relationships between variables that random utility models cannot recognize. This study considered activity -travel information, personal data and household characteristics of students as attributes for model development and observed that the age of the student and distance of school from home plays a significant role in deciding the mode choice of school trips.

Opis:
In recent years, China has put forward policies to improve rural infrastructure and promote the development of rural industries causing to dramatic transition in the living and employment conditions. Moreover, under the pressure of the high expenditure of living and the difficulty of finding jobs, new changes have taken place in the spatial behavior pattern of farmers’ residence and employment. Based on a field survey of 839 observations in 123 villages in Poyang Lake basin, China, we developed indicators to evaluate the suitability of rural living facilities (SLF) and work facilities (SWF). Multinomial logit regression model was used to measure the relationship between SWF, SLF and the spatial behavior patterns of farmers. The results show that: (1) SWF development in rural areas lags behind SLF; (2) Higher SLF is most distributed in suburban areas ; (3) Higher SWF is mostly distributed in suburban towns and characteristic towns; (4) The effects of SLF and SWF on the spatial behavior patterns of farmers are significantly positive; (5) Farmers in the urban-rural amphibious pattern usually obtain a higher income level, and also bring vitality to the countryside.
W ostatnich latach Chiny przedstawiły politykę poprawy infrastruktury wiejskiej i promowania rozwoju przemysłu wiejskiego, powodując istotne zmiany w warunkach życia i zatrudnienia. Ponadto, pod presją wysokich wydatków na życie i występujących trudności ze znalezieniem pracy, nastąpiły nowe zmiany w przestrzennym wzorcu zachowań rolników w miejscu zamieszkania i pracy. Na podstawie ankiety terenowej obejmującej 839 obserwacji w 123 wioskach w dorzeczu jeziora Poyang w Chinach, opracowaliśmy wskaźniki do oceny przydatności ułatwiania życia na wsi (SLF) i ułatwiania pracy (SWF). Do pomiaru związku między SWF, SLF a przestrzennymi wzorcami zachowań rolników zastosowano wielomianowy model regresji logitowej. Wyniki pokazują, że: (1) rozwój SWF na obszarach wiejskich pozostaje w tyle za SLF; (2) SLF jest najbardziej rozpowszechniony na obszarach podmiejskich, podczas gdy; (3) Wyższe SWF są rozprowadzane głównie w miejscowościach podmiejskich i miejscowościach charakterystycznych; (4) Wpływ SLF i SWF na przestrzenne wzorce zachowań rolników jest znacząco pozytywny; (5) Rolnicy funkcjonujący w układzie miejsko-wiejskim zwykle uzyskują wyższy poziom dochodów, a także wnoszą witalność wsi.
