Resembling a Viper: Implications of Mimicry for Conservation of the Endangered Smooth Snake

2014

The phenomenon of Batesian mimicry, where a palatable animal gains protection against predation by resembling an unpalatable model, has been a core interest of evolutionary biologists for 150 years. An extensive range of studies has focused on revealing mechanistic aspects of mimicry (shared education and generalization of predators) and the evolutionary dynamics of mimicry systems (co-operation vs. conflict) and revealed that protective mimicry is widespread and is important for individual fitness. However, according to our knowledge, there are no case studies where mimicry theories have been applied to conservation of mimetic species. Theoretically, mimicry affects, for example, frequency…

Politicisation as a Speech Act: A Repertoire for Analysing Politicisation in Parliamentary Plenary Debates

2021

This chapter analyses the actual speech acts of politicisation among parliamentarians, which also makes it possible to set the current debates among European Union (EU) scholars in a wider context. My aim is to sketch a scheme for distinguishing different aspects of politicisation, referring to concepts of politics (sphere or activity and its specific aspects), to the politicisation of topics or persons, to its time dimensions (past, present, and future), to different activities of politicisation (adversaries, unintended changes, the actors themselves), as well as to opposing evaluations of politicisation. The data set consists of the plenary debates of the UK House of Commons, the (West) G…

To act or not to act : Debating the climate change agenda in the United States Congress

2020

Most climate change actions take place in the international context in terms of multilateral negotiations and accords or in bilateral agreements between heads of the state. Parliaments or legislatures such as the United States Congress are in a crucial position when it comes to converting agreements or aims to action in domestic politics. The United States has played a volatile role in international negotiations on climate change. From categorically rejecting the Kyoto protocol during the George W. Bush administration, President Barack Obama announced that the United States would join the Paris Climate Accord prior to President Donald J. Trump's announcement of the withdrawal of the United …

Lauksaimniecības zemes izmantošanas ietekmējošie faktori Rembates pagastā

2015

Bakalaura darbā “Lauksaimniecības zemju apsaimniekošie ietekmējošiem faktoriem Remabates pagastā” mērķis ir noskaidrot aktuālo lauksaimniecībā izmantojamo zemju struktūru un to apsaimniekošanu ietekmējošos faktorus Rembates pagastā. Literatūras apskatā tiek aplūkotas zemes izmantošanas problēmas pasaules un Eiropas mērogā, kā arī vispārīgā zemes situācija Latvijā. Pētījuma ietvaros izveidots kartogrāfiskais materiāls, kurā attēloti pašreizējie zemes lietojuma veidi Rembates pagastā, kas papildināti ar zemes apsekojuma laikā fiksētiem foto materiāliem. Paralēli zemes kartēšanai tika veikta zemes īpašnieku anketēšana. Nozīmīgākie faktori, kas ietekmē zemes apsaimniekošanu Rembates pagastā ir …

Generation of anti-azoxystrobin monoclonal antibodies from regioisomeric haptens functionalized at selected sites and development of indirect competi…

2012

Azoxystrobin is a modern strobilurin fungicide used around the world to combat prime diseases affecting highly valuable crops. Accordingly, residues of this chemical are frequently found in food, even though mostly under maximum tolerated levels. We herein describe the development of an indirect competitive immunoassay for the determination of azoxystrobin residues. A panel of monoclonal antibodies displaying subnanomolar affinity to azoxystrobin was generated using, as immunizing haptens in mice, four functionalized derivatives carrying the same spacer arm located at different rationally chosen positions. This collection of antibodies was thoroughly characterized with homologous and hetero…

Adriamycin Permeability of the Rat Bladder under Different Conditions

1983

Abstract Fifty female Sprague-Dawley rats were treated with 1.4 or 2.4 mg. adriamycin intravesically. Radioimmunological measurement of serum concentrations were performed up to 3 hours post-instillation in normal bladder mucosa, cystitis, and after electrocoagulation, under different filling conditions, as well as with the use of a detergent (Tween 80). The serum concentrations achieved were markedly higher after electrocoagulation or cystitis; altogether they reached only 1/6,000 of the instilled concentration. These studies on the rat bladder suggest that perioperative instillation of adriamycin to prevent recurrence is not contraindicated shortly before or after transurethral resection …

Three new species of the subgenus Neoribates (Neoribates) (Acari, Oribatida, Parakalummidae) from Nepal

2014

Three new parakalummid mites of the subgenus Neoribates (Neoribates), N. (N.) parabulanovae sp. n., N. (N.) paramacrosacculatus sp. n. and N. (N.) pararotundus sp. n., are described from Nepalese soils. Neoribates (Neoribates) parabulanovae sp. n. is morphologically most similar to N. (N.) bulanovae Grishina, 2009, N. (N.) rotundus Aoki, 1982 and N. (N.) setiger Balogh & Mahunka, 1978, however, it differs from N. (N.) bulanovae by the body length, body and leg integument, morphology of bothridial setae, absence of aggenital setae, length of interlamellar setae and location of adanal setae ad3; from N. (N.) rotundus by the body size, body integument, morphology of bothridial setae and le…

ADI schemes for valuing European options under the Bates model

2018

This paper is concerned with the adaptation of alternating direction implicit (ADI) time discretization schemes for the numerical solution of partial integro-differential equations (PIDEs) with application to the Bates model in finance. Three different adaptations are formulated and their (von Neumann) stability is analyzed. Ample numerical experiments are provided for the Bates PIDE, illustrating the actual stability and convergence behaviour of the three adaptations. peerReviewed

Speaking of politics in parliament : experiences of writing a book on the digitized Bundestag debates, 1949–2017

2022

This article consists of ex post methodological reflections on the procedures and practices that I applied in my monograph Politik als parlamentarischer Begriff: Perspektiven aus den Plenardebatten des Deutschen Bundestags (Leverkusen, 2021). The book analyses through 18 parliamentary terms the conceptualization of politics in German Bundestag plenary debates from 1949 to 2017. The book was an illustration of my long-term aim of combining political theorizing with the empirical analysis of debate. In writing the book, my guiding idea was to apply Ludwig Wittgenstein’s point, that the meaning of a concept lies in its use, to an analysis of how parliamentary debates open a perspective on the …
