Bird pollination in South African Salvia species
2006
Abstract Approximately one-fourth of the more than 900 world-wide distributed Salvia species (Lamiaceae) is ornithophilous. With few exceptions they occur in the New World, being predominantly pollinated by hummingbirds. In the Old World only Salvia africana-lutea and the recently described Salvia thermarum, both from the Cape Province of South Africa, were observed to be pollinated by sunbirds and white-eyes. Among the 23 South African Salvia species Salvia lanceolata is a further candidate for being bird pollinated. For the first time we describe and illustrate its pollination by Nectarinia chalybea and Zosterops pallidus. We compare the ornithophilous syndrome of the three mentioned Salv…
Boards of directors: composition and effects on the performance of the firm
2018
This paper analyses the structure of boards of directors and its impact on business performance, which is approximated by economic profitability and the Tobin’s Q ratio. We focus on three basic aspects of boards that have been reviewed in the recent reform of the Good Governance Code: the size of boards, their independence and their diversity. For the study of diversity, we use an index that integrates not only the gender of board members, but also their age and nationality, since these are factors that can influence the knowledge, experience and skills of the directors. The results confirm a high degree of compliance with the recommendations of the Good Governance Code, and suggest that th…
Globalization of Monitoring Practices: The Case of American Influences on the Dismissal Risk of European CEOs
2013
Accepted version of an article from the Journal of Economics and Business This study examines globalization of monitoring practices by focusing on how American (U.S.) influences on European firms impact the dismissal risk for these firms' CEOs. Specifically, we argue that the stronger short term orientation of the American corporate governance system increase the dismissal performance sensitivity faced by European CEOs, indirectly and directly. The former materializes via European firms cross-listing on U.S. exchanges, the latter results from European firms hiring U.S. independent board members. Both influences are expected to result in increased dismissal performance sensitivity. Based on …
Energy certification of buildings: A comparative analysis of progress towards implementation in European countries
2010
Abstract The Energy Performance Building Directive (Directive 2002/91/EC) introduced the compulsory energy certification of buildings in the EU from 2006 and it has played a key role in the common policy to monitor and reduce energy consumption. In order to assess the experience gained in this field in Europe overall, and in particular against the highly diverse settings of the different European nations, this paper examines the extent to which the Directive has been implemented by the 27 EU Member States. This is done via a comparative analysis assisted by two different indicators: of uniformity and of excellence. The measure of uniformity makes it possible to assess the degree of harmony …
Insight into the role of the zeolitization process in enhancing the adsorption performance of kaolinite/diatomite geopolymer for effective retention …
2021
Abstract Diatomite/kaolinite-based geopolymer (GP) was synthesized and incorporated in zeolitization process (Z/GP) to investigate the role of the zeolite phases in inducing its retention capacity of the dissolved Sr (II) ions in water. The retention of Sr (II) ions using Z/GP in comparison with GP was evaluated based on both batch and fixed-bed column studies. In the batch study, the zeolitized geopolymer (Z/GP) shows enhancement in the Sr (II) retention capacity (193.7 mg/g) as compared to the normal geopolymer (102 mg/g). Moreover, the recyclability studies demonstrate higher stability for Z/GP than GP with a retention percentage higher than 90% for five reusing runs. The kinetic and the…
Previous fire occurrence, but not fire recurrence, modulates the effect of charcoal and ash on soil C and N dynamics in Pinus pinaster Aiton forests.
2021
Abstract Understanding the effects of fire history on soil processes is key to characterise their resistance and resilience under future fire events. Wildfires produce pyrogenic carbonaceous material (PCM) that is incorporated into the soil, playing a critical role in the global carbon (C) cycle, but its interactions with soil processes are poorly understood. We evaluated if the previous occurrence of wildfires modulates the dynamic of soil C and nitrogen (N) and microbial community by soil ester linked fatty acids, after a new simulated low-medium intensity fire. Soils with a different fire history (none, one, two or three fires) were heat-shocked and amended with charcoal and/or ash deriv…

Preparation protocols for SEM visualization of charred fossil plants: the case of Weichselia reticulata pinnule anatomy
2021
The cosmopolite Mesozoic fern Weichselia reticulata presents many peculiarities in the anatomy of its stem as well as in the architecture of its leaves. Previous analyses of the ultrastructure of their pinnule laminas provided some insight on xeromorphic traits. In this work new protocols for the preparation of charred compression foliage specimens embedded in a limestone matrix for their observation under SEM are presented, which enhance the observation of different plant tissues. The preparation with HCl allows for the visualization of the whole lamina, from the upper to the lower epidermis, which had not been done to date. Additionally, collodion, latex, or wax coverings of the fossils b…
Audiovizuālo mediju lokalizācijas procesa salīdzinājums Latvijā un Igaunijā: ierunāšana un subtitri, nākotnes perspektīvas
2018
Digitalizācija ir kļuvusi par vadošo spēku visā pasaulē, un audiovizuālie mediji ir ieguvuši nozīmīgu lomu izklaides un informācijas nozarēs, tādēļ veids, kā šie mediji tiek patērēti, mainās arvien straujāk. Tādās nelielās valstīs kā Latvija un Igaunija lokalizācija un tulkošana ir svarīgas nozares. Ja cilvēki šajās valstīs vēlas patērēt medijus no citām kultūrām un nācijām, tiem bieži vien nepieciešams tulkojums. Maģistra darbā “Audiovizuālo mediju lokalizācijas procesa salīdzinājums Latvijā un Igaunijā: ierunāšana un subtitri, nākotnes perspektīvas” tiks atklātas un analizētas atšķirības starp šīm abām valstīm audiovizuālo mediju lokalizācijas kontekstā.
Is Board Gender Diversity a Driver of CEO Compensation?: Examining the Leadership Style of Institutional Women Directors
2017
In this investigation, we aim at examining the influence of institutional female directors on CEO compensation. Specifically, we investigate the impact of institutional female directors as a whole, differentiating by whether female directors have business ties with the firms’ boards on which they sit (pressure-sensitive female directors) or do not have business links (pressure-resistant female directors). We hypothesize that there is a nonlinear association, specifically quadratic, between institutional, pressureresistant and pressure-sensitive female directors on boards, and CEO compensation. Our findings show that CEO compensation decreases with low levels of institutional female director…
