Opis:
Using previously established knowledge about survey mode preferences distribution in a population can be one of many ways of improving representativeness and quality of data gathered by survey research. Apart from mode preference existence and stability, the main problem concerns the question: which of the sources of information about mode preference could be treated as trustworthy. Because real observed choices are typically treated as better predictors of future choices than declaration only, this paper tries to answer the question: ‘Are the declarations a good predictor of preference in comparison to real choices?’ For this purpose, it uses combined data from 1) the 2015 Polish mixed-mode ESS experiment and 2) data from ESS8 in Poland. The multinomial logistic regression survey preference model includes socio-demographic variables accompanied by declaration/choice control variable. The results suggest significant differences between choices/declarations. Findings could be used to refine the contact strategies used in surveys.

Opis:
The Polish Biobanking Network was created to connect Polish biobanks and gain information about their collections, thus facilitating their cooperation both in the national and international area. Based on MIABIS (Minimum Information About BIobank data Sharing) and considering the specificity of the Polish scientific community, two surveys were created. The aim of the first survey was to collect general information about Polish biobanks, e.g. their localization and type of collected material. The second survey was more detailed and concerned the biobank’s structure, information about collected material, willingness to share the collected material, implementation of an informatics system. Significant information about Polish biobanks could be obtained through appropriate recognition of the biobank’s scope of practice and correctly asked questions. The analysis of collected results could give a full picture of Polish biobanks.

Opis:
The paper presents selected problems related to the quality assessment from the statistical perspective of survey data based on Internet sources. Internet access is consequently expanding all over the world. In parallel with the running development of other new technologies, it is pervading daily life and business activities more and more. It also has influenced surveys practice to a large extent as a research tool for collecting both primary and secondary data, and it also challenges surveys to research the Internet population. Moreover, as the Internet and its entities are able to register all activities that are performed on the web, issues related to big data and organic data processing as well as their applications arise. As a result of decreasing response rates and increasing survey costs, Internet data collection is constantly growing. Due to many advantages, Internet surveys are used widely and this process seems to be inevitable. However, it needs to be emphasised that Internet surveys are developing in practice faster than the methodology in this area. Hence, a lot of problems can be identified, especially when considering the quality of data based on Internet sources. The following issues are discussed as the most far-reaching in the prism of statistical survey methodology: determination of the sampling frame, self-selection and related estimates bias, as well as under/over-coverage.
W artykule przedstawiono – z perspektywy statystycznej – wybrane problemy związane z oceną jakości badań opartych na źródłach internetowych. Dostęp do internetu konsekwentnie poszerza się na całym świecie. Równolegle, wraz z rozwojem innych nowych technologii, przestrzeń internetowa przenika coraz bardziej codzienne życie społeczeństwa, a także funkcjonowanie firm. Wszechobecny internet wywarł także wpływ na badania rynku i opinii: jako narzędzie badawcze do zbierania danych pierwotnych i wtórnych oraz w kontekście badania populacji internetowej. Ponadto, ponieważ internet i jego podmioty rejestrują wszystkie działania podejmowane w sieci, pojawiła się kwestia związana z wykorzystaniem i analizą big data i danych organicznych. W połączeniu z problemem malejących stóp odpowiedzi w badaniach i z rosnącymi ich kosztami źródła internetowe, ze względu na wiele zalet, są w powszechnym użyciu. Coraz szersze wykorzystanie internetu i jego zasobów wydaje się nieuniknione. Należy jednak podkreślić, że w praktyce proces realizacji badań na podstawie źródeł internetowych wyprzedził prace metodologiczne. Można wskazać wiele problemów, szczególnie w kwestii jakości uzyskiwanych danych. Artykuł prezentuje wybrane z nich, istotne zwłaszcza z punktu widzenia statystyki: kwestie związane z poprawnym zdefiniowaniem operatu losowania, samodoborem, nadmiernym/niedostatecznym pokryciem i powiązanymi z nimi obciążeniami estymatorów.

Opis:
The author reviews theory and application of rotation methods in sample surveys in Poland. He begins with reviewing designs of the surveys across time, depending on different objectives, focusing on partial rotation of sub-samples, and considers estimation problems and data quality issues generally. Next, he refers to some articles and books about surveys published over time, starting with Wilks (1940), Patterson (1950), Eckler (1955), Woodruff (1963), Rao and Graham (1964), Bailar (1975), Duncan and Kalton (1987) and Kalton and Citro (1993). He mentions also early Polish papers on rotation methods (Kordos (1966, 1967, 1971, 1982); Lednicki, 1982; Szarkowski and Witkowski, 1994), and concentrates on Polish household surveys, mainly Household Budget Survey (HBS), Labour Force Survey (LFS) and EU Statistics on Living Conditions and Income (EU-SILC). Special attention is devoted to last research on rotation sampling done by Polish sampling statisticians: Ciepiela et al. (2012), Kordos (2002), Kowalczyk (2002, 2003, 2004), Kowalski (2006, 2009), Kowalski and Wesołowski (2012) and Wesołowski (2010). Concluding remarks are given at the end.

Household Budget Survey
Opis:
The presence of a child with disabilities in a family presents more challenging conditions than the presence of a non-disabled child. One of the difficulties is of financial nature. One of the parents often has to give up their job to care for the child, which shrinks the household income. At the same time, the family has higher expenses resulting from, e.g. costs of treatment. All this increases the risk of falling into poverty. The goal of this paper is to analyse the financial situation of households with a disabled child, mainly in the context of poverty, and compare it to the financial situation of households with non-disabled children. The study is based on data from Polish Household Budget Survey, covering two years, 2014 and 2016. The study revealed that families with a disabled child are generally poorer than families with non-disabled children. The financial situation improved over the studied period in both types of families, but the improvement in the families with a disabled child was much greater. The main factor in reducing the risk of poverty in both types of families is the education attainment level of the reference person (the household head), which should be at least upper secondary.

Survey statisticians have been dealing with the issues of nonresponse in sample surveys for many years. Due to the complex nature of the mechanism, so far it has not been easy to find a general solution to this problem. In this paper, several aspects of this topic will be elaborated on: the survey unit nonresponse bias has been examined alternatively by taking response amounts which are fixed initially and also by taking the response amounts as random variables. An overview of the components of the bias due to nonresponse will be performed. Nonresponse bias components are illustrated for each alternative approach and the amount of bias was computed for each case.

In order to deliver the minimum safety conditions for movement of the ships towards restricted waters, urgent survey operations are required whenever we deal with natural disasters; unreliable chart information or uncharted areas requires. In recent years, there has been a huge development in positioning and survey technology. Simultaneously, charts production techniques and GIS software are easily accessible. In this circumstance, a research project was made in order to assess the possibility of developing existing capabilities of emergency hydrographic survey. The toolkit was designed to allow the swift production of usable bottom representation and survey of navigational aids, with a focus on navigational safety, rather than bottom contour accuracy.

Opis:
The crime economy has lately become a popular field of research because of regular increases in crime rates. Economists’ interest in crime analysis goes back to Becker’s (1968) model. “Cost‑benefit” analysis determined the crime preferences of rational individuals in this model. According to this analysis, if the benefit from the crime is higher than the cost to be faced, the individual will be willing to commit the crime. One of the factors studied in the crime phenomenon is migration. The main reason for migration is unemployment and poverty. The main purpose of this study is to determine the relationship between youth unemployment and crime rates by migration-receiving regions. By this purpose, aggregated crime rates, as well as non-aggregated crime rates (property crime, theft, and violent crime), were used. Also, the youth unemployment rate has been subdivided by gender differences and educational levels. We prefer to use spatial econometrics models in this study because of the unemployment rate, and crime rate showing the regional cluster pattern. Migration-receiving is considered as regions neighboring.

High-resolution Multibeam Echosounder shallow water surveys should not be performed with DGPS (Differential Global Positioning System), especially where feature detection is a priority. Despite the fact that International Hydrographic Organization most demanding Special Order Specification allows for 2 meters horizontal positioning level, it poorly interacts with horizontal centimetric level nadir footprint, causing degradation of bathymetric data.
Wysokorozdzielcze pomiary prowadzone echosondą wielowiązkową nie mogą być wykonywane w połączeniu z użyciem pozycjonowania opartego na systemie DGPS, zwłaszcza gdy priorytetem jest rozpoznanie cech obiektu. Wprawdzie specyfikacja IHO odnośnie pomiarów specjalnych dopuszcza błąd pozycji w płaszczyźnie horyzontu w granicach 2 m, to należy być świadomym tego, że skutkuje to degradacją pomiarów prowadzonych echosondą, nominalnie gwarantujących centymetrowe dokładności.

Radon problem has a special attention in many countries in the world and the most of them have established national radon programmes. The radon issues in Serbia have not been approached in a systematic and organized way. Currently, there are many research groups and institutions working in radon fi eld, and it is a good basis to integrate all these activities into a comprehensive national programme to defi ne the strategic objectives and action plan for the next few years. Also, Serbia as a candidate for membership in the EU is obliged to harmonize its legislation, including the fi eld of radiation protection in which the radon issues has an important role. In this report, a brief history of radon research, present status and plans for the future activity on radon issues in Serbia are presented. Regarding the long-term plans, the establishment and implementation of the Radon Action Plan with the primary goal of raising awareness about the harmful effects of public exposure to radon and implementing a set of measures for its reduction. In that sense, the synergy between the national, regional and local organizations responsible for public health and radiation protection must be achieved.

Opis:
This paper scrutinizes the behavior of individual forecasters included in the Consensus Forecast inflation data for the US. More precisely, we try to determine whether individual forecasters deviate systematically from each other. We examine whether the ranking of forecasters is the same over time. The full micro data set includes 74 forecasters over the period 1989M10-2011M3. The results clearly indicate that the forecasters behave quite persistently so that, for instance, the ranking of forecasters does not change over time. Even so, we also find that the survey values imply reasonable values for the hybrid form of the New Keynesian Phillips curve and that forecaster’s disagreement is positively related to the size of forecast errors.
Przeanalizowano zachowanie się poszczególnych ośrodków prognostycznych ujętych w prognozach Consensus Forecast dla inflacji w USA. Starano się określić, czy poszczególne prognozy systematycznie odbiegają od siebie. W szczególności zbadano, czy ranking ośrodków jest taki sam w czasie. Pełny zestaw danych obejmuje 74 prognostyków w okresie 1989M10– 2011M3. Wyniki wyraźnie wskazują, że prognostycy zachowują się bardzo konsekwentnie tak, że na przykład, ranking ośrodków nie zmienia się w czasie. Ponadto pokazano, że prognostycy są zgodni co do hybrydowej postaci neokeynesowskiej krzywej Phillipsa oraz że różnice pomiędzy nimi są dodatnio skorelowane z wielkością błędów prognozy.
