Researchers and survey designers face the challenge of low data quality as web surveys are often not compelling. Thus, participants’ engagement declines while completing a survey resulting in participants tend to apply satisficing behavior (e.g., speeding, straight-lining) in order to complete the questionnaire or even break-off the completion of the questionnaire. Due to satisficing behavior, ...

We show empirically using panel data at the plot and farm level and based on a model incorporating supervision costs, risk, credit-market imperfections and scale-economies associated with mechanization that small-scale farming is inefficient in India. Larger farms are more profitable per acre, more mechanized, less constrained in input use after bad shocks, and employ less per-acre labor than s...

Applications in which data take nonnegative values but have a substantial proportion of values at zero occur in many disciplines. The modeling of such “clumped-at-zero” or “zero-inflated” data is challenging. We survey models that have been proposed. We consider cases in which the response for the non-zero observations is continuous and in which it is discrete. For the continuous and then the d...

Background The responsiveness of a health system is considered to be an intrinsic goal of  health systems and an essential aspect in performance assessment. Numerous studies have analysed health system responsiveness and related concepts, especially across different countries and health systems. However, fewer studies have applied the concept for the evaluation of specific healthcare delivery s...

During an archaeological project various data sources and various levels of accuracy and geometric details will be needed in 3D modelling. The subject has been discussed based on the experiences gathered during the Finnish Jabal Haroun Project (FJHP) in Petra, Jordan. Especially the data collection processes aerial photogrammetry, tachymeter measurements, and terrestrial photogrammetry are cons...

A data marketplace is an online venue that brings owners, brokers, and consumers together facilitates commoditisation of amongst them. Data pricing, as a key function marketplace, demands quantifying the monetary value data. considerable number studies on pricing can be found in literature. This paper attempts to comprehensively review state-of-the-art existing provide general understanding thi...

In Bangladesh, use of modern contraceptive methods has increased dramatically in the last decade. However, the level of use has not been the same between rural clusters. This dissertation investigates the plausible reasons for areal variations in use of modern contraception in rural Bangladesh. This study randomly selects sixteen rural clusters as sub-samples from the 1991 Contraceptive Prevale...
