[= <i>Luehea candicans</i> Mart.]</p> <p> Pohl’s original collection is kept in W where he worked and lived (Stafleu & Cowan 1976 –1988: 315), and where we found only two specimens reported by the author to the name <i>L. microphylla</i> and collected by him in Brazil (B. Wallnöfer, pers. comm.). These two specimens are syntypes of <i>L. microphylla</i>, and the previous typification of Cunha (1985) needs to be corrected (Art. 9.2 of the ICN), since it represents the first-step lectotype of <i>L. microphylla</i> and now requires the second-step typification by the way of subsequent lectotypification (Art. 9.17 of the ICN). For this reason, we designated herein the specimen <i>Pohl s.n.</i> (W0071087) the second-step lectotype of <i>L. microphylla</i>, that agree well with the morphological description presented in the protologue. Based on the type materials, the application of the name <i>L. microphylla</i> Pohl is confirmed as a heterotypic synonym of <i>L. candicans,</i> as previously accepted by Cunha (1985).</p>Published as part of <i>Gerace, Samuele, Bovini, Massimo G., Peruzzi, Lorenzo & Baumgratz, José Fernando A., 2022, Typification of names in the neotropical genus Luehea (Malvaceae: Grewioideae), pp. 180-188 in Phytotaxa 542 (2)</i> on pages 183-184, DOI: 10.11646/phytotaxa.542.2.5, <a href="http://zenodo.org/record/6415980">http://zenodo.org/record/6415980</a>
Spillover and Competition Effects: Evidence from the sub-Saharan African Banking Sector
No full textThis paper examines the efficiency effects of foreign bank entry on domestic banks in sub- Saharan Africa during the period 1999–2006. Using a recently compiled dataset on foreign bank presence, the competition and spillover effects of North–South, regional and nonregional South–South banks are distinguished. The results show that the competitive pressure on domestic banks' net interest margins emanates only from regional South–South banks. There is evidence of spillover effects from North-South and regional South-South banks on domestic banks. As domestic banks invest in foreign technologies, their overhead costs increase in the short-run. Non-regional South-South banks seem to have little effect on the efficiency of domestic banks.sub-Saharan Africa, efficiency, South–South banks, spillover

Notes —Among the three gatherings mentioned in the protologue of A. nobile by Müller-Argoviensis (1860a), Woodson (1951) selected the collection “St.-Hilaire 760” (St.-Hilaire C1-760) as the type. However, since this gathering has more than one specimen, it was necessary to narrow Woodson’s (1951) typification by electing the best-preserved specimen as the second-step lectotype of A. nobile (P barcode P00639581) (ICN article 9.17; Turland et al. 2018). Also, Müller-Argoviensis (1860a) indicated the gathering Pohl 1229 in the prologue of A. pohlianum but did not cite in which herbarium the type would be deposited. Thus, we selected a material with flower remains from this collection as the lectotype of A. pohlianum (W No. W 0048493) (ICN article 9.3; Turland et al. 2018).Published as part of Castello, Ana Carolina Devides, Pereira, Andreza Stephanie De Souza, Shimizu, Gustavo Hiroaki, Zuntini, Alexandre Rizzo, Simões, André Olmos & Koch, Ingrid, 2022, Taxonomy and nomenclature of Aspidosperma (Apocynaceae), pp. 239-277 in Phytotaxa 571 (3) on page 258, DOI: 10.11646/phytotaxa.571.3.1, http://zenodo.org/record/728466
Enhancing the Digital Backchannel Backstage on the Basis of a Formative User Study
No full textContemporary higher education with its large audiences suffers from passivity of students. Enhancing the classroom with a digital backchannel can contribute to establishing and fostering active participation of and collaboration among students in the lecture. Therefore, we conceived the digital backchannel Backstage specifically tailored for the use in large classes. At an early phase of development we tested its core functionalities in a small-scale user study. The aim of the study was to gain first impressions of its adoption, and also to form a basis for further steps in the conception of Backstage. Regarding adoption we particularly focused on how Backstage influences the participants' questioning behavior, a salient aspect in learning. We observed that during the study much more questions were uttered on Backstage than being asked without backchannel support. Regarding the further development of Backstage we capitalized on the participants' usability feedback. The key of the refinement is the integration of presentation slides in Backstage, which leads to an interesting reconsideration of the user interactions of Backstage
The effects of school geometry in the shaping of a desired child
No full textIn this chapter we explore how school geometry becomes a technology for the government of the self, and how the pedagogical devices of school geometry conduct students’ ways of thinking and acting. We contend that students, in their working with pedagogical devices, engage in a training process in which they learn to regulate their own conduct so that they perceive space through the trained eyes of reason provided by Euclidean, school geometry. Our contribution is an analysis of the power effects of school geometry in terms of the fabrication of children’s subjectivities towards the shaping of the desired child of society.</p

Defending the “Satanic Verses” : constructive engagement: British-Iranian relations and the right to freedom of expression (1989-2004)
No full textThis thesis aims to conceptualize what is often referred to in diplomacy, as a policy of “constructive engagement”, by employing neoliberal-institutionalist theories and conflict resolution approaches. The adopted “model for constructive engagement” serves as the theoretical framework and centres on the basic assumption that non-coercive diplomacy coupled with the offer of incentives is best suited at resolving conflict as well as promoting human rights in international relations. Rather than looking at determinants of foreign policy making, the thesis focuses, therefore, on the actual exercise of power and influence in international relations. As such, power, both in terms of a state’s available assets as well as seen as a form causation, is considered the crucial variable in determining diplomatic manoeuvring and negotiation behaviour. The empirical context for the research project is provided by the case of British-Iranian relations during the period from 1989 to 2004. The narrative is divided into two parts: the first one deals with the impact of the fatwa against Salman Rushdie by Ayatollah Khomeini on bilateral relations and investigates British diplomacy towards Tehran, which followed the European Union’s policy of “Critical Dialogue” with Iran. Whilst the promotion of human rights was on the agenda of the “Critical Dialogue”, findings indicate that contrary to other EU member states, most notably Germany, Whitehall was able to genuinely pursuing a policy of “constructive engagement”, demanding meaningful changes in Iranian behaviour. However, findings also show that Britain’s priority was at resolving the “Rushdie affair” and not necessarily at promoting and protecting human rights in Iran. The second part of the narrative looks at the “Comprehensive Dialogue” which was implemented by the European Union in 2000 and established a direct linkage between economic rewards and the improvements of human rights in Iran. Whilst the Iranian government and parliament met EU demands, the country’s maze of power centres, most notably those dominated by hardliners and conservatives, worked against any meaningful improvements in the protection and respect of human rights. Both narratives indicate to what extent diplomacy and negotiations were influenced by domestic constituents, referred to as the Two-Level Game, as well as by asymmetries of interdependence between the EU and Iran. Overall, the data implies that constructive engagement, whilst subject to political and economic interdependence, constitutes an effective form of human rights diplomacy
Mathematics Teachers as Products and Agents:To Be and Not to Be. That’s the Point!
No full textStudying mathematics teachers in the Political invites to understand how teachers’ subjectivities emerge in the entanglement of the individual in discursive-material formations. We focus on the power effects of the expert discourses by international agencies such as OECD and UNESCO in the fabrication of the mathematics teacher’s subjectivity. Deploying a Foucault-inspired discourse analysis on a series of documents produced by these agencies, we argue that nowadays cultural thesis about who the mathematics teacher should be are framed in a double bind of the teacher as a policy product and as a sales agent. Narratives about the mathematics teacher are made possible within a dispositive of control, which makes mathematics education and mathematics teachers the cornerstone for realizing current market-oriented, competitive, and globalized societies.</p
