The dynamics of the leader follower relationship

This study examined the forces that affect the influence relationship between leaders and followers in a public sector organisational setting. The study is motivated by the ambition of presenting a critical perspective of the social influence process referred to as leadership. The forces were explored by studying leaders and followers engaged in their normal work context. A variation of a critical ethnographic methodology after Alvesson and Sköldberg (2005) was utilised in order to identify and explain how the dynamics impacted upon the leader follower relationship. An extended period of fieldwork was conducted within a large unitary local government authority (referred to through out the study as the ABC), during which observations and informal interviews with observed constituents were conducted and documentary evidence collected. Subsequently, an interpretive reflection of selected materials was undertaken in order to inform a critical perspective of the dynamics uncovered and the impact they had on the relationship between leaders and followers.These dynamics are shown to be predominantly external to the leader follower dyad. The dynamics of ambiguity, environment, resources, symbiosis, politics and "playing the game" impact on the relationship to create an influence relationship distinct from that detailed in normative models of leadership. The organisation comprises high levels of ambiguity; not least in the roles individuals play as leaders and followers. The transactional basis of the relationship with central government informs the basis of relationships between leaders and followers but in doing so also constricts the possibilities for leadership within the organisation. The environment is therefore an influential dynamic in leader follower relationships. Leaders and followers use the availability, acquisition and utilisation of resources to negotiate the position of their leadership and followership. Leaders are aware that they need followers as a resource and followers need leaders as they control access to resources. The relationship takes the form of a complex social symbiosis in which both component parts support each other. The relationship has a political bias. The use of politics underpins the independence of followers who are capable of acting in ways that can frustrate leaders. Finally, the two constituent parts of the relationship are engaged in playing a game, the rules of which are not explicitly stated, but can involve behaviour deemed to be illegitimate or non-sanctioned. The normative position of followers as a largely homogenous group, docile and subject to the influences of leaders is shown to be unsubstantiated. This study concludes that followers have the capacity to act under their own agency toward their own goals and aspirations; and highlights the use of political behaviour to discredit leadership as an asymmetrical influence relationship. This study concludes by asserting that political behaviour corresponds to leadership and subsequently achieves its emancipatory intent.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

Meta-Analysis

Do informational interventions shape electoral choices and thereby promote political accountability? The chapters in Part II of this book provided answers to this question in particular contexts. The studies individually provide rich insights not only into the impact of interventions that were common to all studies, but also on the effects of alternative interventions that were specific to each one. In this chapter, we assess the larger lessons that we can glean from our coordinated studies. As outlined in Chapter 3, all studies seek to test common hypotheses about the impact of harmonized informational interventions, using consistent measurements of outcome variables. Our preregistered analysis allows us to evaluate whether, pooling data from the set of studies in the initiative, information about politician performance led voters to alter their electoral behavior. It also informs a discussion about the conditions under which they did or did not do so. We find that the overall effect of information is quite precisely estimated and not statistically distinguishable from zero. The analysis shows modest impacts of information on voters' knowledge of the information provided to them. However, the interventions did not appear to shape voters’ evaluations of candidates, and, in particular, they did not discernibly influence vote choice. This slate of null results obtains in nearly all analyses for the individual country studies too. Nor is there strong evidence of impact on voter turnout, though under some specifications we find suggestive evidence that bad news may boost voter mobilization. Our results are robust to different analytic strategies and across a variety of modeling and dataset construction choices. The findings also suggest that the estimated effect in our missing study would have needed to be extremely large to alter our broader conclusions. The size of our meta-analysis reduces the chances that null estimated effects stem from low statistical power, and the fact that our results are so consistent across the individual studies limits the possibility that our mostly null effects are due to idiosyncrasies in implementation or study design. In the rest of this chapter, we first describe the prespecified approach that we use to analyze the pooled dataset. We then report our main findings, point out the consistency of results across studies, and report robustness checks. Next we consider several possible reasons for our null findings by testing the prespecified hypotheses. The most plausible reason for the null effects stems from the failure of the interventions to shape voters’ perceptions of politicians; we do not find evidence, however, that this is due to partisan or ethnic attachments or other heuristic substitutes for information. It is critical to underscore the similarities of these interventions to previous treatments in the experimental research literature and to interventions for which donor organizations in the transparency space routinely advocate. Indeed, our interventions were crafted by researchers with substantial country-specific expertise, usually in collaboration with local NGOs. Our null results across wide array of contexts therefore provide an important baseline of evidence against which future studies can be weighed. This chapter could be profitably read in conjunction with Chapter 3, which discusses the common interventions and our measurement of key variables, but it can be read as a standalone chapter as well

4D In-Situ Microscopy of Aerosol Filtration in a Wall Flow Filter

The transient nature of the internal pore structure of particulate wall flow filters, caused by the continuous deposition of particulate matter, makes studying their flow and filtration characteristics challenging. In this article we present a new methodology and first experimental demonstration of time resolved in-situ synchrotron micro X-ray computed tomography (micro-CT) to study aerosol filtration. We directly imaged in 4D (3D plus time) pore scale deposits of TiO2 nanoparticles (nominal mean primary diameter of 25 nm) with a pixel resolution of 1.6 μm. We obtained 3D tomograms at a rate of ∼1 per minute. The combined spatial and temporal resolution allows us to observe pore blocking and filling phenomena as they occur in the filter’s pore space. We quantified the reduction in filter porosity over time, from an initial porosity of 0.60 to a final porosity of 0.56 after 20 min. Furthermore, the penetration depth of particulate deposits and filtration rate was quantified. This novel image-based method offers valuable and statistically relevant insights into how the pore structure and function evolves during particulate filtration. Our data set will allow validation of simulations of automotive wall flow filters. Evolutions of this experimental design have potential for the study of a wide range of dry aerosol filters and could be directly applied to catalysed automotive wall flow filters

The impact of the COVID-19 pandemic on recovery from cardiac surgery: 1-year outcomes

AIMS: The outbreak of COVID-19 was potentially stressful for everyone, and possibly heightened in those having surgery. We sought to explore the impact of the pandemic on recovery from cardiac surgery. METHODS AND RESULTS: A prospective observational study of 196 patients who were ≥18years old undergoing cardiac surgery between 23rd March and 4th July 2020 (UK lockdown) was conducted. Those too unwell or unable to give consent/complete the questionnaires were excluded. Participants completed (on paper or electronically) the impact of event (IES-R) (distress related to COVID-19), depression (CES-D) and EQ-5D-5L (quality of life, HRQoL) questionnaires at baseline, one week after hospital discharge, and six weeks, six months and 1-year post-surgery.Questionnaire completion was >75.0% at all timepoints, except at one week (67.3%). Most participants were male (147 (75.0%)), white British (156 (79.6%)) with an average age 63.4years. No patients had COVID-19. IES-R sand CES-D were above average at baseline (indicating higher levels of anxiety and depression) decreasing over time. HRQoL pre-surgery was high, reducing at one week but increasing to almost pre-operative levels at six weeks, and exceeding pre-operative levels at six months and 1-year. IES-R and CES-D scores were consistently higher in women and younger patients with women also having poorer HRQoL up to 1-year after surgery. CONCLUSION: High levels of distress were observed in patients undergoing cardiac surgery during the COVID-19 pandemic with women and younger participants particularly affected. Psychological support pre- and post-operatively in further crises or traumatic times, should be considered to aid recovery. REGISTRATION: Clinicaltrials.gov ID:NCT04366167

WWER-1000 Nuclear reactor simulator for education. Part A': Overview of simulator physico-mathematical model components

A review of phylogenetic studies carried out together with morphological ones shows that a major problem with most early studies is that they concentrated on techniques and used material or strains of fungi that in most cases were not carefully reference, and in a worrying number of cases wrongly named. Most classical species, particularly of microfungi, are not represented by adequate type material, or other authoritatively identified cultures or specimens, that can serve as DNA sources for phylogenetic study, or for developing robust identification systems. Natural classifications of fungi therefore suffer from the lack of reference strains in resultant phylogenetic trees. In some cases, epitypification and neotypification can solve this problem and these tools are increasingly used to resolve taxonomic confusion and stabilize the understanding of species, genera, families, or orders of fungi. This manuscript discusses epitypification and neotypification, describes how to epitypify or neotypify species and examines the importance of this process. A set of guidelines for epitypification is presented. Examples where taxa have been epitypified are presented and the benefits and problems of epitypification are discussed. As examples of epitypification, or to provide reference specimens, a new epitype is designated for Paraphaeosphaeria michotii and reference specimens are provided for Astrosphaeriella stellata, A. bakeriana, Phaeosphaeria elongata, Ophiobolus cirsii, and O. erythrosporus. In this way we demonstrate how to epitypify taxa and its importance, and also illustrate the value of proposing reference specimens if epitypification is not advisable. Although we provided guidelines for epitypification, the decision to epitypify or not lies with the author, who should have experience of the fungus concerned. This responsibility is to be taken seriously, as once a later typification is made, it may not be possible to undo that, particularly in the case of epitypes, without using the lengthy and tedious formal conservation and rejection processes

Phylogenetic Revision of Savoryellaceae and Evidence for Its Ranking as a Subclass

Morphology, phylogeny, and molecular clock analyses were carried out on Savoryellaceae in order to understand the placements of taxa in this family. Ascotaiwania and Neoascotaiwania formed a well-supported separate clade in the phylogeny of concatenated partial SSU, LSU, TEF, and RPB2 gene data. These two genera share similar morphological features, especially in their asexual morphs, indicating that they are congeneric. Hence, we synonymize Neoascotaiwania under Ascotaiwania. Ascotaiwania hughesii (and its asexual morph, Helicoon farinosum) and Monotosporella setosa grouped in a clade sister to Pleurotheciales and are excluded from Ascotaiwania which becomes monophyletic. A novel genus Helicoascotaiwania is introduced to accommodate Ascotaiwania hughesii and its asexual morph, Helicoon farinosum. A novel species, Savoryella yunnanensis is introduced from a freshwater habitat in Yunnan Province, China. Comprehensive descriptions and illustrations are provided for selected taxa in this family. In addition, we provide evolutionary divergence estimates for Savoryellomycetidae taxa and major marine based taxa to support our phylogenetic and morphological investigations. The taxonomic placement of these marine-based taxa is briefly discussed. Our results indicate that the most basal group of marine-based taxa are represented within Lulworthiales, which diverged from ancestral Sordariomycetes around 149 Mya (91–209) and Savoryellomycetidae around 213 Mya (198–303)

Global Spore Sampling Project: A global, standardized dataset of airborne fungal DNA

Novel methods for sampling and characterizing biodiversity hold great promise for re-evaluating patterns of life across the planet. The sampling of airborne spores with a cyclone sampler, and the sequencing of their DNA, have been suggested as an efficient and well-calibrated tool for surveying fungal diversity across various environments. Here we present data originating from the Global Spore Sampling Project, comprising 2,768 samples collected during two years at 47 outdoor locations across the world. Each sample represents fungal DNA extracted from 24 m3 of air. We applied a conservative bioinformatics pipeline that filtered out sequences that did not show strong evidence of representing a fungal species. The pipeline yielded 27,954 species-level operational taxonomic units (OTUs). Each OTU is accompanied by a probabilistic taxonomic classification, validated through comparison with expert evaluations. To examine the potential of the data for ecological analyses, we partitioned the variation in species distributions into spatial and seasonal components, showing a strong effect of the annual mean temperature on community composition.publishedVersio

Naming and outline of Dothideomycetes-2014 including proposals for the protection or suppression of generic names

Article 59.1, of the International Code of Nomenclature for Algae, Fungi, and Plants (ICN; Melbourne Code), which addresses the nomenclature of pleomorphic fungi, became effective from 30 July 2011. Since that date, each fungal species can have one nomenclaturally correct name in a particular classification. All other previously used names for this species will be considered as synonyms. The older generic epithet takes priority over the younger name. Any widely used younger names proposed for use, must comply with Art. 57.2 and their usage should be approved by the Nomenclature Committee for Fungi (NCF). In this paper, we list all genera currently accepted by us in Dothideomycetes (belonging to 23 orders and 110 families), including pleomorphic and nonpleomorphic genera. In the case of pleomorphic genera, we follow the rulings of the current ICN and propose single generic names for future usage. The taxonomic placements of 1261 genera are listed as an outline. Protected names and suppressed names for 34 pleomorphic genera are listed separately. Notes and justifications are provided for possible proposed names after the list of genera. Notes are also provided on recent advances in our understanding of asexual and sexual morph linkages in Dothideomycetes. A phylogenetic tree based on four gene analyses supported 23 orders and 75 families, while 35 families still lack molecular data
