TY - JOUR A1 - Reith, Florian A1 - Seyfried, Markus T1 - Balancing the Moods BT - Quality Managers’ Perceptions and Actions Against Resistance JF - Higher education policy N2 - Quality management (QM) has spread around the world and reached higher education in Europe in the early 1990s (Mendel, 2006, 137; Kernegger and Vettori, 2013, 1). However, researchers were rather more interested in national quality assurance policies (macro-level) and accreditation systems (meso-level) than in intra-organizational perspectives about the day-to-day implementation of quality assurance policies by various actors (micro-level). Undoubtedly, organizational change is a challenging endeavor for all kinds of groups. On the one hand, it provides the opportunity of further development and innovation, but on the other hand, it exposes organizations and actors to the risk of losing established structures and accepted routines. Like in many other organizations, actors may not necessarily perceive change as a promoter of innovation and development. Instead, they may consider change as a threat to the existing status quo or, as March points out, as an “interplay between rationality and foolishness” (March, 1981, 563). Consequently, change provokes either affective or behavioral actions (Armenakis and Bedeian, 1999, 308–310), such as, for example, resistance. Anderson (2006, 2008) and Lucas (2014) have shown, for example, that academic resistance is an important issue. However, Piderit characterizes resistance as a multidimensional construct (Piderit, 2000, 786–787) subject to a wide variety of issues related to quality and QM. Although QM has been described as a “fashion” (Stensaker, 2007, 101) in the higher education sector that provokes many different reactions, its implementation in higher education institutions (HEIs) is still a rather unexplored field. Thus, the evidence provided by Anderson (2006, 2008) and others (Newton, 2000, 2002; McInnis et al., 1995; Fredman and Doughney, 2012; Lucas, 2014; etc.) needs to be expanded, because they only consider the perspective of academia. In particular, the view of other actors during the implementation of quality assurance policies is a missing piece in this empirical puzzle. Nearly nothing is known about how quality managers deal with reactions to organizational change like resistance and obstruction. Until now, only a few studies have focused on intra-organizational dynamics (see, for example: Csizmadia et al., 2008; Lipnicka, 2016). Besides the lack of research on the implementation of quality assurance policies in HEIs, quality managers seem to be an interesting subject for further investigations because they are “endogenous” to institutional processes. On the one hand, quality managers are the result of quality assurance policies, and on the other hand, they influence the implementation of quality assurance policies, which affect other actors (like academics, administrative staff, etc.). Here, quality managers, as members of an emerging higher education profession, are involved in various conflict lines between QM, HEI management and departments, which need further research (Seyfried and Pohlenz, 2018, 9). Therefore, the aim of our paper is twofold: firstly, to answer the question of how quality managers perceive resistance, and secondly, which measures they take in situations of perceived resistance. We offer a new research perspective and argue that resistance is not merely provoked by organizational change; it also provokes counter-reactions by actors who are confronted with resistance. Thus, resistance seems to be rather endogenous. To theorize our argument, we apply parts of the work of Christine Oliver (1991), which provides theoretical insights into strategic responses to institutional processes, ranging from acquiescence to manipulation (Oliver, 1991, 152). We, therefore, investigate the introduction of QM in teaching and learning, and the emergence of quality managers as higher education professionals as one of the results of quality assurance policies. Consequently, the introduction of QM may be considered as an institutional process provoking reactions and counter-reactions of various organizational units within HEIs. These circumstances are constitutive for how quality managers deal with resistance and other reactions toward organizational change. We use this theoretical framework to analyze the German higher education sector, because this particular case can be considered as a latecomer in New Public Management reforms (Schimank, 2005, 369) and Germany is a country where academic self-governance plays a very important role, and strongly influences academics’ behavior when it comes to organizational change (Wolter, 2004). Our empirical results are based on a mixed-methods research design and integrate half-structured interviews and a nationwide survey at the central level in German HEIs, which excludes faculty members of QM (decentral level). They reveal that quality managers take different types of action when resistance occurs during the implementation of quality assurance policies. Furthermore, quality managers mainly react with different tactics. These tactics seem to be relevant for convincing academics and for the enhancement of their commitment to improve the quality of teaching and learning, instead of provoking further resistance or avoidance practices. This article proceeds as follows: the next sections describe the context and explain our main theoretical concepts referring to the work of Oliver (1991) and others. After that, we present our case selection and the methodological framework, including the data sources and the operationalization of selected variables. Finally, we provide our empirical results about quality managers’ perceptions on resistance and we draw conclusions.

A1 - Grimm, Volker A1 - Kramer-Schadt, Stephanie T1 - The dimensionality of stability depends on disturbance type JF - Ecology letters N2 - Ecosystems respond in various ways to disturbances. Quantifying ecological stability therefore requires inspecting multiple stability properties, such as resistance, recovery, persistence and invariability. Correlations among these properties can reduce the dimensionality of stability, simplifying the study of environmental effects on ecosystems. A key question is how the kind of disturbance affects these correlations. We here investigated the effect of three disturbance types (random, species-specific, local) applied at four intensity levels, on the dimensionality of stability at the population and community level. We used previously parameterized models that represent five natural communities, varying in species richness and the number of trophic levels. We found that disturbance type but not intensity affected the dimensionality of stability and only at the population level. The dimensionality of stability also varied greatly among species and communities. Therefore, studying stability cannot be simplified to using a single metric and multi-dimensional assessments are still to be recommended.

These are, e.g., bodily experience/s such as shame and fear, everyday and institutional discourses and practices, but also manifestations of differences and particularities that we transform into phenomena such as “norms”, “binary systems” and “binary organisations”. The analysis of seemingly cyclic “Othering processes” and patterns of violence shows how people who identify as trans*, inter*, or non-binary have to live through and embody epistemological, emotional, and/or physical violence. At the same time, the descriptions illustrate numberless potential forms of resistance and change.

A1 - Vorburger, Christoph T1 - Rapid evolution of symbiont-mediated resistance compromises biological control of aphids by parasitoids JF - Evolutionary applications N2 - There is growing interest in biological control as a sustainable and environmentally friendly way to control pest insects. Aphids are among the most detrimental agricultural pests worldwide, and parasitoid wasps are frequently employed for their control. The use of asexual parasitoids may improve the effectiveness of biological control because only females kill hosts and because asexual populations have a higher growth rate than sexuals. However, asexuals may have a reduced capacity to track evolutionary change in their host populations. We used a factorial experiment to compare the ability of sexual and asexual populations of the parasitoid Lysiphlebus fabarum to control caged populations of black bean aphids (Aphis fabae) of high and low clonal diversity. The aphids came from a natural population, and one-third of the aphid clones harbored Hamiltonella defensa, a heritable bacterial endosymbiont that increases resistance to parasitoids. We followed aphid and parasitoid population dynamics for 3months but found no evidence that the reproductive mode of parasitoids affected their effectiveness as biocontrol agents, independent of host clonal diversity. Parasitoids failed to control aphids in most cases, because their introduction resulted in strong selection for clones protected by H.defensa. The increasingly resistant aphid populations escaped control by parasitoids, and we even observed parasitoid extinctions in many cages. The rapid evolution of symbiont-conferred resistance in turn imposed selection on parasitoids. In cages where asexual parasitoids persisted until the end of the experiment, they became dominated by a single genotype able to overcome the protection provided by H.defensa. Thus, there was evidence for parasitoid counteradaptation, but it was generally too slow for parasitoids to regain control over aphid populations. It appears that when pest aphids possess defensive symbionts, the presence of parasitoid genotypes able to overcome symbiont-conferred resistance is more important for biocontrol success than their reproductive mode.

However, coevolution in the framework of eco-evolutionary theory has not been addressed directly. Combining experiments with an algal host and its viral parasite, and mathematical model analyses we show eco-evolutionary dynamics in antagonistic coevolving populations. The interaction between antagonists initially resulted in arms race dynamics (ARD) with selective sweeps, causing oscillating host-virus population dynamics. However, ARD ended and populations stabilised after the evolution of a general resistant host, whereas a trade-off between host resistance and growth then maintained host diversity over time (trade-off driven dynamics). Most importantly, our study shows that the interaction between ecology and evolution had important consequences for the predictability of the mode and tempo of adaptive change and for the stability and adaptive potential of populations.

Because today only the most potent, but also most persistent anticoagulant rodenticides of the second generation remain available to control this strain, new rodenticide solutions are required. RESULTS: Feeding trials in the laboratory confirmed a significant level of efficacy, which was corroborated by field trials in the Munsterland resistance area. After frequency and level of resistance were assessed by blood clotting response tests, field trials were conducted with bait containing coumatetralyl at 375 mg kg(-1) and cholecalciferol at 50 mg kg(-1) or 100 mg kg(-1). Control success was 94% when a large rat infestation comprising 42% resistant animals was treated. Another field trial applying the combination to a rat population that had survived a preceding treatment with bromadiolone resulted in a 99.5% control success according to the first census day, but with some increase in rat activity during subsequent census days. CONCLUSION: The combination of coumatetralyl and cholecalciferol is a promising alternative approach to the most potent second-generation anticoagulants in resistance management, particularly in respect of environmental risks, such as secondary poisoning.
