The Effect of Predator Population Dynamics on Batesian Mimicry Complexes.
2022
Understanding Batesian mimicry is a classic problem in evolutionary biology. In Batesian mimicry, a defended species (the model) is mimicked by an undefended species (the mimic). Prior theories have emphasized the role of predator behavior and learning as well as evolution in model-mimic complexes but have not examined the role of population dynamics in potentially governing the relative abundances and even persistence of model-mimic systems. Here, we examined the effect of the population dynamics of predators and alternative prey on the prevalence of warning-signaling prey composed of models and mimics. Using optimal foraging theory and signal detection theory, we found that the inclusion …
Diversity in warning coloration: selective paradox or the norm?
2019
Aposematic theory has historically predicted that predators should select for warning signals to converge on a single form, as a result of frequency-dependent learning. However, widespread variation in warning signals is observed across closely related species, populations and, most problematically for evolutionary biologists, among individuals in the same population. Recent research has yielded an increased awareness of this diversity, challenging the paradigm of signal monomorphy in aposematic animals. Here we provide a comprehensive synthesis of these disparate lines of investigation, identifying within them three broad classes of explanation for variation in aposematic warning signals: …
Incidentality on a continuum: A comparative conceptualization of incidental news consumption
2020
This article seeks to contribute to theorizing the dynamics of incidental news consumption. Through an analysis of 200 semi-structured interviews with people in Argentina, Finland, Israel, Japan, and the United States, we show that intentionality in news consumption can be viewed on a continuum, which goes from deliberately setting apart time to access the news on specific outlets to skimming through unsought-for news on social and broadcast media, with intermediate practices such as respondents setting up an environment where they are more or less likely to encounter news. Drawing on structuration theory, this article conceptualizes incidental news in the context of the wider media environ…
Incidencia del iusnaturalismo en las políticas publicas de prevención de violencia domestica en Panamá
2022
La tesis pretende demostrar que la violencia doméstica es un problema público que se enfrenta adecuadamente desde una comprensión iusnaturalista del Derecho, situando en el centro y como anterior a cualquier ejercicio de poder la dignidad de la persona humana. Para justificar dicha pretensión, fue necesario dividir la tesis en tres partes: 1. Los fundamentos iusnaturalistas, 2. La violencia domestica como atentado contra la paz, y 3. La respuesta panameña frente a la violencia doméstica. En la primera parte se ha realizado un recorrido histórico que lleva a comprender el iusnaturalismo actual como un esquema previo de consciencia personal, que es ajeno a cualquier forma de organización soci…

"Rozkosz" dla zmysłów, czyli język kart dań
2021
This article is about language used in menus. The recently changing approach to cooking and eating is also reflected in language that describes food. Restaurant menus are a clear example of this. It is because eating, i. e. experiencing the taste of dishes, does not only take using our tongue, but it also involves using language. Some restaurant owners are aware of the relationship between taste and word, which is reflected in the way some dishes are described in menu cards offered to customers. The purpose of the article is to analyse menus of selected restaurants and to show some linguistic tricks used by restaurant owners to encourage customers to eat in their restaurants.
Starptautiskā sadarbība administratīvajā procesā
2016
Maģistra darbā „Starptautiskā sadarbība administratīvajā procesā” pētīts, kādos veidos administratīvajā procesā ir iespējama sadarbība ar ārvalstīm. Starptautiskā sadarbība administratīvajā procesā Latvijā nav pētīta, tāpēc darba mērķis bija noskaidrot, vai administratīvajā procesā starptautiskā sadarbība ir iespējama, un kādos veidos tā var izpausties. Lai sasniegtu maģistra darba mērķi, tika veikta ārvalstu juridiskās literatūras, tiesu prakses un normatīvā regulējuma izpēte. Tika noskaidrots, ka starptautiskā sadarbība ietver dokumentu paziņošanu ārvalstī esošam adresātam, dokumentu un informācijas izsniegšanu ārvalsts iestādei, pierādījumu iegūšanu, kā arī ārvalsts administratīvo aktu a…
Transnacionālo korporāciju apvienošanās un tās ietekme uz attīstību
2020
Mūsdienās ir raksturīga strauja konkurences palielināšanās starp mazākiem un lielākiem uzņēmumiem, tāpēc tirgus dalībnieki meklē iespējas ātrākai sava uzņēmuma attīstībai un jaunu tirgus apgūšanu. Viens no attīstības veidiem ir apvienoties ar citu tirgus dalībnieku vai to pārņemt. Apvienošanās un iegūšanas darījumi ir pazīstami kopš 19. gadsimta beigām. Pētījums mērķis ir, pamatojoties uz transnacionālo korporāciju teorētiskiem aspektiem un finanšu datu analīzi, novērtēt transnacionālo korporāciju apvienošanās darījumu ietekmi uz uzņēmumu attīstību. Tiek analizēts “Nordea” un “DNB” banku apvienošanās darījums, kas pārtapa par “Luminor” banku, definējot darījuma ietekmi uz transnacionālo kor…
