Opis:
The life quality results from the degree of needs satisfaction, what comes among other from goods and services consumption. The aim of the work is to widespread the outcomes from author’s research attempting to find the determinants of the life quality, using more advanced statistical methods. These methods, on the base of individual distributions and at assumption that ordinal scale is treated as a ratio scale, may widen the analyses of sources conditioning the life quality. With various degree of details, there were presented the results of the life quality statistical modelling. Particular emphasis on usefulness of logit regression model and the use of cumulative probability was applied. Statistical data were drawn from realization of three research projects funded by National Science Centre in 2011-2015.
Jakość życia jest rezultatem stopnia zaspokojenia potrzeb co wynika m.in. z konsumpcji dóbr i usług. Celem pracy jest upowszechnienie wyników prób poszukiwania przez autorkę determinant jakości życia z wykorzystaniem bardziej zaawansowanych metod statystycznych, które przy np. założeniu, iż skalę porządkową potraktuje się jako ilorazową mogą poszerzyć analizę źródeł warunkujących jakość życia uzyskaną na podstawie rozkładów indywidualnych. Zaprezentowano przy różnym stopniu szczegółowości wyniki modelowania jakości życia ze szczególnym podkreśleniem użyteczności stosowania modelu regresji logitowej z użyciem prawdopodobieństwa skumulowanego. Dane statystyczne zaczerpnięto z realizacji trzech projektów badawczych finansowanych przez NCN w latach 2011-2015.

Opis:
The dissolved oxygen content in surface waters is one of the vital indicators for human water quality usage as well as the aquatic plant and animal environmental life sustainability. Parshall flumes are one of the important ejector devices that are successfully used for oxygen requirement satisfying in various irrigation, wastewater, and ecosystems. However, the present study aimed to manage and improve various waterworks aeration efficiency through integrated modeling of experimental and analytical analysis as well as their operation conditional parameters for the Parshall flumes configuration. On the basis of the experiment work data sets run results, the principal component regression (PCR), partial least squares (PLS), and ridge regression (RR) techniques are used to develop the required aeration efficiency prediction models for such aerators by interrelating the impact of Parshall flumes characteristics and configurations, as well as various water flow rates on aeration efficiency. The predictive models developed in the study were statistically compared to the experimental data. The comparison confirms a good reliability and high accuracy. Considering the proposed aeration models, the optimum design of the new Parshall flumes can be successfully facilitated.

Opis:
Understanding societal preferences towards health is vital in public decisions on nancing health technologies. Thought experiments in which respondents choose between health states are used to understand the importance of individual criteria. Competing models of preference structure can be compared by their ability to explain empirical observations. One of the key challenges when constructing such models is that they have to aggregate preferences dened in multiple-criteria space. In the present paper, we test whether treating the impact of health worsening (dened using EQ-5D-5L descriptive system, i.e. decomposing health status in ve criteria) as a fuzzy concept can improve the model fit. To test if fuzzy approach to multiple-criteria preferences aggregation is valid, we compare a standard, crisp model (SM) with two models using fuzzy sets (JKL, previously proposed in the literature; and FMN introduced here). We nd FMN better than SM, and SM better than JKL. Anxiety/depression and pain/discomfort seem to weigh most in preferences. According to FMN, self-care and usual activities are associated with largest imprecision in preferences. The respondents are susceptible to framing eects when time unit is changed: e.g. measuring the duration in days results in short intervals mattering more than when expressed as weeks. We conclude that the fuzzy-based framework is promising, but requires careful work on the exact specication.

Opis:
Successful crop production depends initially on the availability of high-quality seed. Seed viability and vigour of four kenaf varieties during storage were investigated. Seeds of each variety were packed inside thick polythene bags and kept in Seed Stores under ambient conditions in two storage locations (Federal University of Agriculture, Abeokuta (FUNAAB) (29.8°C, 59.10 RH%) and Institute of Agricultural Research and Train- ing, Ibadan (27.5°C, 64.68 RH%) for 240 days (8 months).  Seeds were sampled during storage at 0, 60, 120, 180 and 240 days and tested for seed viability and seedling vigour index. Data collected on seed viability and seedling vigour were analyzed using ANOVA, mean separation using Duncan Multiple Range Test at 5% probability level and PROBIT analysis. The results showed differential responses in the two quality traits due to differences in storage location and varieties. Ibadan storage location provided more favourable conditions for higher seed quality compared to Abeokuta location while Ifeken 400 and Tianung had the best storage potential. The study showed that under ambient humid tropical conditions, storage period should not exceed 180 days (6 months) in order to maintain higher physiological quality with little or no cost. The PROBIT result revealed that the highest seed shelf life (longevity) of kenaf seeds of 8 to 9 months was derived for seeds of Ifeken 400 and Tianung stored in Ibadan and Abeokuta. The shortest shelf life of 6 months was esti- mated for Ifeken 100 stored in both locations.
