Perspectives of tax reforms in Croatia: expert opinion survey
2014
In order to shape tax reform it is necessary objectively to assess the current stateof-the- art of and of the outlook for the tax system. After having reviewed all previous reforms in the light of the consumption-based (interest- adjusted) concept of direct taxation, which was almost systematically implemented in Croatia in 1994, we present the results of a broad expert opinion survey about the Croatian tax system. The most interesting results suggest the maintenance/(re)introduction of different tax incentives and reduced VAT rates, rejection of a flat tax as well as decrease of tax brackets, an increase in alcohol and tobacco duties, the introduction of a financial activities tax, a furth…
Motivation, Burnout, and Engagement During Critical Transitions from School to Work
2012
Educational transitions and the transition from school to working life present substantial challenges for youth in modern societies. This chapter presents results from two longitudinal studies, the FinEdu study and Helsinki Longitudinal Student Study (HELS), in which young people were followed for several years during critical educational transitions. These longitudinal studies focus on how engagement and burnout change and what role these two factors play during transitions, as well as investigating the effect of motivation and the strategies young people apply during their studies. The FinEdu study presents findings on how young people navigate their educational transitions from comprehen…
Cultural environments and the appointment of females directors on boards: An analysis from a global perspective
2020
This is the pre-peer reviewed version of the following article: Cultural environments and the appointment of female directors on boards: An analysis from a global perspective, which has been published in final form at https://doi.org/10.1002/csr.2065. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Use of Self-Archived Versions. Hofstede's six cultural dimensions (power distance, individualism, masculinity, uncertainty avoidance, long‐term orientation and indulgence) has received little attention concerning the presence of female directors on boards. Moreover, past research has only focussed on four or five of these six cultural dimensi…
Weak warning signals can persist in the absence of gene flow.
2019
Significance With our comprehensive set of field (model survival), laboratory (controlled learning, palatability, toxin analysis), and molecular data, we provide evidence that polymorphism can persist in an aposematic population, despite expectations of positive frequency-dependent selection. We show that this can happen if prey species carrying a strong signal can exploit predator learning to elicit broad avoidance of many signals, even if predators only have experience with a single signal. This could allow novel signals to be protected within a population of aposematic prey. Thus, under the expectations of broad generalization coupled with limited gene flow, weak aposematic signals can p…
Similar Performance of Diploid and Haploid Males in an Ant Species without Inbreeding Avoidance
2013
AbstractUnder haplodiploidy, a characteristic trait of all Hymenoptera, femalesdevelop from fertilised eggs, and males from unfertilised ones. Males aretherefore typically haploid. Yet, inbreeding can lead to the production ofdiploid males that often fail in development, are sterile or are of lowerfertility. In most Hymenoptera, inbreeding is avoided by dispersal flightsof one or both sexes, leading to low diploid male loads. We investigatedcauses for the production of diploid males and their performance in ahighly inbred social Hymenopteran species. In the ant Hypoponera opacior,inbreeding occurs between wingless sexuals, which mate within themother nest, whereas winged sexuals outbreed dur…
Long-term effects of delayed motherhood in mice on postnatal development and behavioural traits of offspring
2003
BACKGROUND: Some epidemiological evidence tentatively suggests that children born to older parents may have lower intellectual development and maturity than children whose parents are younger. This study aims to analyse the long-term effects of delayed motherhood in mice on postnatal development and behavioural traits later in life. METHODS: Hybrid females, either at the age of 10 weeks or 51 weeks, were individually housed with a randomly selected 12-14 week old hybrid male. After a postweaning resting period of 1 week, dams were caged again with a new randomly selected 12-14 week old male. This sequence of events was repeated until old females reached the end of their reproductive life. R…
Young adults personal concerns during the COVID-19 pandemic in Finland: an issue for social concern
2020
PurposeThis study focuses on how young adults face the COVID-19 pandemic by investigating their personal concerns about mental well-being, career/studies and economic situation. The authors investigated how young adults' (aged 18–29) personal concerns differ from older people's concerns (aged 30–65) and which person- and context-related antecedents relate to personal concerns.Design/methodology/approachData of Finnish young adults aged 18–29 (n = 222), who participated in the “Corona Consumers” survey (N = 1,000) in April 2020, were analyzed by path analysis and compared to participants aged 30–65 by independent samples t-test.FindingsYoung adults were significantly more concerned about the…
Gestational exposure to cocaine alters cocaine reward
2006
Exposure of the developing foetus to drugs of abuse during pregnancy may lead to persistent abnormalities of brain systems involved in drug addiction. Mice prenatally exposed to cocaine (25 mg/kg), physiological saline or non-treated during the last 7 days of pregnancy were evaluated in adulthood for the rewarding properties of cocaine (3, 25 and 50 mg/kg), using the conditioned place preference procedure. Dams treated with physiological saline gained significantly less weight over the course of gestation than controls; no other differences were observed in the maternal and offspring data. All the animals developed preference to 3 and 25 mg/kg of cocaine, but those treated prenatally with c…
Psychologische Operationsvorbereitung, Stressbewältigung und perioperativer Status
2008
Zusammenfassung. In Studien zum Einfluss einer psychologischen Operationsvorbereitung auf den postoperativen Anpassungsstatus von Patienten wurde bislang einer möglichen Interaktion der Art der Vorbereitung mit Persönlichkeitsmerkmalen des Patienten nur wenig Beachtung geschenkt. Ziel der vorliegenden Arbeit ist die Analyse von Wechselwirkungen zwischen unterschiedlichen Formen der psychologischen Operationsvorbereitung und bestimmten Merkmalen des Patienten im Hinblick auf subjektive und objektive Indikatoren der perioperativen Patientenbelastung. In einer Untersuchung an 97 chirurgischen Patienten (Nasennebenhöhlen- oder Septumoperationen; 66 Männer und 31 Frauen) konnte nachgewiesen wer…
Efectos conductuales y neuroquímicos del consumo de éxtasis y cocaína en ratones adolescentes.
2009
La 3,4-metilendioximetanfetamina (MDMA), una sustancia popularmente conocida como éxtasis, es una droga ilícita consumida habitualmente por adolescentes y adultos jóvenes. Además, el policonsumo es una práctica habitual entre los usuarios de la MDMA, siendo la cocaína una de las drogas más frecuentemente asociadas a esta sustancia. El objetivo del presente trabajo fue evaluar los efectos a corto y largo plazo que se producen tras la administración de la MDMA (5, 10, o 20 mg/kg) sola o en combinación con cocaína (25 mg/kg) en ratones adolescentes. En el estudio sobre el efecto agudo, observamos que ambas drogas administradas individual o simultáneamente incrementan la actividad motora. La do…
