The use of performance information in budgetary decision‐making by legislators: is estonia any different?

Abstract: The goal of this article is to examine to what extent legislators in Estonia use performance information in budgetary decision-making. Interviews with the members of the finance committee of the parliament show that legislators make only limited use of the formal documents containing performance information. Instead, they rely, for the most part, on informal social networks for gathering information they consider necessary for budget discussions. According to the legislators, the main reasons for limited use of performance information are the following: the documents containing performance are too long and cumbersome, the legislative budget process is too time-constrained, and the parliament has only a limited role in making substantive changes to the budget. The study also indicates that more experienced politicians are less interested in performance information than the novices but there are no significant differences between legislators from governing and opposition parties.

Increasing incidence of thyroid cancer in the Nordic countries with main focus on Swedish data

Abstract: Radiofrequency radiation in the frequency range 30 kHz–300 GHz was evaluated to be Group 2B, i.e. ‘possibly’ carcinogenic to humans, by the International Agency for Research on Cancer (IARC) at WHO in May 2011. Among the evaluated devices were mobile and cordless phones, since they emit radiofrequency electromagnetic fields (RF-EMF). In addition to the brain, another organ, the thyroid gland, also receives high exposure. The incidence of thyroid cancer is increasing in many countries, especially the papillary type that is the most radiosensitive type. We used the Swedish Cancer Register to study the incidence of thyroid cancer during 1970–2013 using joinpoint regression analysis. In women, the incidence increased statistically significantly during the whole study period; average annual percentage change (AAPC) +1.19 % (95 % confidence interval (CI) +0.56, +1.83 %). Two joinpoints were detected, 1979 and 2001, with a high increase of the incidence during the last period 2001–2013 with an annual percentage change (APC) of +5.34 % (95 % CI +3.93, +6.77 %). AAPC for all men during 1970–2013 was +0.77 % (95 % CI −0.03, +1.58 %). One joinpoint was detected in 2005 with a statistically significant increase in incidence during 2005–2013; APC +7.56 % (95 % CI +3.34, +11.96 %). Based on NORDCAN data, there was a statistically significant increase in the incidence of thyroid cancer in the Nordic countries during the same time period. In both women and men a joinpoint was detected in 2006. The incidence increased during 2006–2013 in women; APC +6.16 % (95 % CI +3.94, +8.42 %) and in men; APC +6.84 % (95 % CI +3.69, +10.08 %), thus showing similar results as the Swedish Cancer Register. Analyses based on data from the Cancer Register showed that the increasing trend in Sweden was mainly caused by thyroid cancer of the papillary type. We postulate that the whole increase cannot be attributed to better diagnostic procedures. Increasing exposure to ionizing radiation, e.g. medical computed tomography (CT) scans, and to RF-EMF (non-ionizing radiation) should be further studied. The design of our study does not permit conclusions regarding causality.

FOMCON: Fractional-Order Modeling and Control Toolbox

Abstract: In the following chapter, FOMCON toolbox for MATLAB/Simulink is described. The chapter has the following structure. First, an overview of the toolbox is provided in Sect. 6.1. Next, the identification, control, and implementation modules comprising the toolbox are described in Sects. 6.2–6.4, respectively. Illustrative examples are provided for the most important tools available in each module. Finally, in Sect. 6.5 conclusions are drawn.
