The effect of inbreeding rate on fitness, inbreeding depression and heterosis over a range of inbreeding coefficients
2014
Understanding the effects of inbreeding and genetic drift within populations and hybridization between genetically differentiated populations is important for many basic and applied questions in ecology and evolutionary biology. The magnitudes and even the directions of these effects can be influenced by various factors, especially by the current and historical population size (i.e. inbreeding rate). Using Drosophila littoralis as a model species, we studied the effect of inbreeding rate over a range of inbreeding levels on (i) mean fitness of a population (relative to that of an outbred control population), (ii) within‐population inbreeding depression (reduction in fitness of offspring fro…
"I just cursed and opened a beer" : Explaining Mobile Users' Non-Complaining Behavior Through Coping
2015
Many users experience frustrating incidents with mobile applications. However, most users do not complain about their highly negative incidents to the application providers. Such dissatisfied non-complainers cause damage to application providers: they tend to exit, switch, and spread negative word-of-mouth. Therefore, it is important to understand why mobile users do not complain about their highly negative incidents. Within information systems (IS), there are no explanations for this dilemma. To address this gap, we conducted a qualitative study. By utilizing the theory of coping as a theoretical lens, we generated a mobile-specific theory that comprises problem-focused and emotion-focused…
Examining consumers' intention, behavior, and beliefs in mobile banking adoption and continuous usage
2016
Changing consumer behavior continues to have a profound impact on digital banking adoption and prolonged usage in developed and emerging markets. Several factors influence the consumer decision journey when choosing any specific digital channel or combination of channels. Among a variety of digital banking channels, this dissertation research seeks to contribute to the mobile banking (m-banking) literature by examining consumer behavior in m-banking services as well as technology (application) adoption and continuous usage, especially after considering the fact that financial service institutions have entered a time when offering mobile-based services is no longer a novelty but a necessity.…
Volatile compounds released by disturbed and undisturbed adults of Anchomenus dorsalis (Coleoptera, Carabidae, Platynini) and structure of the pygidi…
2011
Volatile compounds produced by adults of Anchomenus dorsalis under undisturbed and disturbed conditions were investigated with an all-glass aeration apparatus. GC-MS analysis of the crude extracts from undisturbed and disturbed adults highlighted four major volatile compounds, undecane, heneicosane, Z-9 tricosene and tricosane, of which significantly more undecane was released by disturbed adults compared to undisturbed beetles. The pygidial glands of adults of A. dorsalis were investigated using light and Transmission Electron Microscopy (TEM). Each gland showed dense aggregates of secretory cells organized into visually distinct lobes; a long collecting canal that drains the secretion tow…
Unfair play? Video games as exploitative monetized services: An examination of game patents from a consumer protection perspective
2019
Video games as a consumer product have changed significantly with the advent of in-game purchasing systems (e.g., microtransactions, ‘loot boxes’). This review examines consumer protections related to in-game purchasing by anticipating some of the potential design strategies that might contribute to higher risk consumer behavior. Attention was directed towards the analysis of patents for potential in-game purchasing systems, with 13 identified on Google Patents. The design features were analysed in relation to the consumer rights and guarantees described in the terms of use agreements of the patent assignees. The analysis revealed that some in-game purchasing systems could be characterized …
Prenatal exposure to diazepam and alprazolam, but not to zolpidem, affects behavioural stress reactivity in handling-naïve and handling-habituated ad…
2002
A gentle long-lasting handling produces persistent neurochemical and behavioural changes and attenuates the impairment in the behavioural reactivity to novelty induced by the prenatal exposure to diazepam (DZ) in adult male rat progeny. This study investigated the consequences of a late prenatal treatment with three GABA/BDZ R agonists (DZ) alprazolam (ALP) and zolpidem (ZOLP)), on different stress-related behavioural patterns, in non-handled (NH), short-lasting handled (SLH) and long-lasting handled (LLH) adult male rats exposed to forced swim test (FST), acoustic startle reflex (ASR) and Vogel test (VT). The effects on motor activity were evaluated in the open field and in the Skinner box…
Hard to catch: Experimental evidence supports evasive mimicry
2021
Most research on aposematism has focused on chemically defended prey, but the signalling difficulty of capture remains poorly explored. Similar to classical Batesian and Müllerian mimicry related to distastefulness, such ‘evasive aposematism' may also lead to convergence in warning colours, known as evasive mimicry. A prime candidate group for evasive mimicry areAdelphabutterflies, which are agile insects and show remarkable colour pattern convergence. We tested the ability of naive blue tits to learn to avoid and generalizeAdelphawing patterns associated with the difficulty of capture and compared their response to that of birds that learned to associate the same wing patterns with distast…

Anotācija Promocijas darba mērķis ir izpētīt faktorus, kas ietekmē pieaugušo veselības izglītības darba organizāciju un vadību primārās veselības aprūpes māsas praksē, ietverot arī indivīda veselības kompetenci veidojošos faktorus, un izveidot uz pierādījumiem balstītus metodiskus ieteikumus pieaugušo veselības izglītības darba organizācijai un vadībai, kas būtu izmantojami gan māszinību studiju programmās, gan primārās veselības aprūpes līmenī strādājošo māsu tālākizglītībā. N= 827 iedzīvotāji un N=106 māsas. Izmantota faktoru analīze, korelācijas analīze, ANOVA, Kruskall-Wallis tests. Noskaidrots, ka indivīda veselības kompetenci ietekmē vairāki galvenie faktori, papildus tiem, dzimums, i…
Microbiome and Probiotics in Acne Vulgaris—A Narrative Review
2022
Acne vulgaris is a chronic disease characterised by the appearance of eruptions such as whiteheads, blackheads, pustules, papules, and cysts. Among factors that cause acne vulgaris are the abnormal keratinisation of the sebaceous canal, bacterial colonisation (Cutibacterium acnes), increased sebum production, genotypic factors, and hormonal disorders. Treatment is often long and tedious, and can lead to a reduction in quality of life and social isolation. The intestinal microbiota is greatly important in the formation of acne lesions. It is also responsible for the proper immunity of the organism. Acne is a disease that can be related to the condition of the digestive tract and its microbio…
Profilaktyka społeczna - edukacja - zdrowie
2018
Dzisiejsza rzeczywistość wiąże się z tym, że dzieci i młodzież narażone są na coraz to nowe czynniki ryzyka, dlatego też rozwój zachowań ryzykownych przybiera na skali. Szczególnie coraz większym i silniejszym zjawiskiem są zachowania ryzykowne z obszaru cyfrowych technologii oraz z zakresu ryzykownych zachowań seksualnych. Prezentowany artykuł przedstawia klasyfikacje problemów i zachowań ryzykownych, a także nurt współczesnej profilaktyki, która raczej koncentruje się na działaniach pozytywnych, związanych z promocją zdrowia, pozytywnym rozwojem dzieci i młodzieży, a także środowiska lokalnego. Celem staje się wykreowanie postaw prospołecznych i prozdrowotnych u młodych ludzi.
