    Spectroscopic investigations of infrared-radiofluorescence (IR-RF) for equivalent dose estimation
    (2022-03-03) Sontag-González, Mariana; Fuchs, Markus
    Infrared radiofluorescence (IR-RF) is a technique with the potential to date sediment deposition beyond 1000 Gy. However, the total IR-RF signal is composed of several emissions whose separate characteristics are still poorly understood. We obtained RF emission spectra for two sediment samples dominated by K-feldspar in the wavelengths ∼600–1000 nm over a wide dose range of up to 4000 Gy to discuss possible effects of neighbouring emissions on the conventional IR-RF De estimation via a photomultiplier tube, which yields a signal integration over a wavelength range of more than 30–40 nm. The studied samples included a modern age and a field-saturated one to assess the emissions’ characteristics at different dose ranges. For these samples, we find no significant influence of neighbouring emissions to the De obtained from the wavelength range typically used for IR-RF.

    The upscaling and out-scaling of ecological intensification: how smallholder farms can inform the science of managing biocontrol at scale
    (2023) Martin, Emily A.; Librán Embid, Felipe; Olagoke, Adewole
    Current objectives to harness agroecological functioning to improve the biological control of crop pests are conditional on a range of ecological, social, economic and cultural mechanisms that may hinder or support the success of such endeavours. Against the backdrop of ongoing work focused on the push-pull technology, a mixed cropping strategy aiming to increase biocontrol in smallholder farms of Sub-Saharan Africa, we review some key challenges and knowledge gaps associated with enhancing and managing biocontrol practices on farms. While major knowledge gaps exist with regard to ecological processes affecting biocontrol success at small to large scales, these can quickly be trumped in terms of capacity for implementation by non-ecological factors such as the structure of social systems and the existence and effectiveness of training networks. We argue that it is our responsibility to formulate questions for biocontrol research that lead to effective, adaptable and resilient solutions for the real-world contexts in which they should be implemented. Consequently, research aiming to understand ecological processes for improved biocontrol must be increasingly transdisciplinary and leave a wide margin for flexible application of ecologically-driven principles.

    Spatial coding for action across spatial scales
    (2023) Fiehler, Katja; Karimpur, Harun
    Humans perform goal-directed actions such as reaching for a light switch or grasping a coffee mug thousands of times a day. Behind the scenes of these seemingly simple actions, the brain performs sophisticated calculations to locate the target object of the action and correctly guide the hand towards it. In this Review, we discuss how the brain establishes spatial representations used for visually guided actions. In addition to reviewing simple tasks and paradigms, we discuss spatial coding in complex and naturalistic environments. We highlight the importance of high-level cognitive factors, such as memory, task constraints, and object semantics, which influence the use of spatial representations for action. To move the field forward, we suggest that future research should integrate across different scales of action spaces from small-scale finger movements to large-scale navigation. Doing so would enable the identification of general mechanisms that underlie spatial coding across different actions and spaces.

    3D Impedance Modelling of Metal Anodes in Solid-State Batteries − Incompatibility of Pore Formation and Constriction Effect in Physical-Based 1D Circuit Models
    (2022-09-08) Eckhardt, Janis K.; Fuchs, Till; Burkhardt, Simon; Klar, Peter J.; Janek, Jürgen; Heiliger, Christian
    A non-ideal contact at the electrode/solid electrolyte interface of a solid-state battery arising due to pores (voids) or inclusions results in a constriction effect that severely deteriorates the electric transport properties of the battery cell. The lack of understanding of this phenomenon hinders the optimization process of novel components, such as reversible and high-rate metal anodes. Deeper insight into the constriction phenomenon is necessary to correctly monitor interface degradation and to accelerate the successful use of metal anodes in solid-state batteries. Here, we use a 3D electric network model to study the fundamentals of the constriction effect. Our findings suggest that dynamic constriction as a non-local effect cannot be captured by conventional 1D equivalent circuit models and that its electric behavior is not ad hoc predictable. It strongly depends on the interplay of the geometry of the interface causing the constriction and the microscopic transport processes in the adjacent phases. In the presence of constriction, the contribution from the non-ideal (porous) electrode/solid electrolyte interface to the impedance spectrum may exhibit two signals that cannot be explained when the porous interface is described by a physical-based (effective medium theory) 1D equivalent circuit model. In consequence, the widespread assumption of a single interface contribution to the experimental impedance spectrum may be entirely misleading and can cause serious misinterpretation.

    La Lucha Continua: A Presentist Lens on Social Protest in Ecuador
    (2023) Schwab, Julia
    Ecuador has one of the most progressive constitutions in Latin America. It defines the state as plurinational and guarantees collective rights to Indigenous people and even to Nature itself. At the same time, the oil sector has been of strategic importance and “national interest” to both right- and left-wing governments for the last decades, contributing with its rents and revenues to around one-third of the state coffers. Therefore, the extractivist model remains unchallenged and still promises development - while reproducing systemic inequalities and a “continuum of violence.” In June 2022, the Indigenous movement called for a nationwide strike to draw attention to the socio-economic crisis following the pandemic. The authorities harshly repressed the mobilization and a racializing media discourse demarcated the “Indigenous” agenda from the needs of “all Ecuadorians,” classifying the protesters as “terrorists” and thus, a threat to the nation. Drawing on ethnographic research, this article discusses the role of extractivism in social mobilization. Exploring the future of social protest in Ecuador in the face of new pressures like climate change and the energy transition, it argues that extractivist patterns will change globally and amplify social discontent and mobilization.

    Selling oneself: Construct and criterion-related validity of impression management in structured interviews
    (2011) Kleinmann, Martin; Klehe, Ute-Christine
    Interviewee impression management has been a long-standing concern in the interview literature. Yet recent insights into the impact of impression management on interviewee performance in structured interviews suggest that interviewee impression management may be more than just a source of bias and a nuisance. Rather, impression management should possess construct-related validity and contribute to the interviews´ criterion-related validity. These hypotheses were tested with 129 participants using a simulated selection interview aimed at university graduates. Results confirmed most of the hypotheses. In particular, interviewee impression management behavior showed construct-related validity across different structured interview types and correlated positively with interviewees´ performance on subsequent typical and maximum performance proxy criteria. Implications and directions for future research are discussed.

    Applicant versus employee scores on self-report emotional intelligence measures
    (2011) Lievens, Filip; Klehe, Ute-Christine; Libbrecht, Nele
    There exists growing interest to assess applicants emotional intelligence (EI) via self-report trait-based measures of EI as part of the selection process. However, some studies that experimentally manipulated applicant conditions have cautioned that in these conditions use of self-report measures for assessing EI might lead to considerably higher scores than current norm scores suggest. So far, no studies have scrutinized self-reported EI scores among a sample of actual job applicants. Therefore, this study compares the scores of actual applicants at a large ICT organization ( n = 109) on a well-known self-report measure of EI to the scores of employees already working in the organization ( n = 239). The current study is the first to show that applicants scores on a self-report measure of EI during the selection process are indeed higher ( d = 1.12) and have less variance ( SD ratio = 0.86/1) than incumbents scores. Finally, a meta-analytic combination of our results with those of earlier research showed that a score increase of about 1 SD in applicant conditions seems to be the rule, regardless of the type of setting, self-report EI measure, and within- versus between-subjects design employed.

    Detection of Saccharopolyspora rectivirgula by quantitative Real-Time PCR
    (2011) Schäfer, Jenny; Kämpfer, Peter; Jäckel, Udo
    The thermophilic actinomycete species Saccharopolyspora rectivirgula has been associated with the exogen allergic alveolitis (EAA). EAA is caused by the inhalation of high amounts of airborne spores that can be found for example in environments of agricultural production, compost facilities, mushroom cultivation rooms, or rooms with technical air moistening. Because of the medical relevance of S. rectivirgula, a reliable detection system is needed. Therefore, a quantitative real-time polymerase chain reaction (qPCR) primer system was designed, targeting the 16S rRNA gene of the type strain S. rectivirgula DSM 43747T and six other S. rectivirgula reference strains. Our investigation showed that S. rectivirgula presumably own four operons of the 16S rRNA gene, which has to be considered for estimation of cell equivalents. Furthermore, the DNA recovery efficiency from these strains was tested in combination with bioaerosol or material sample as well as the influence of non-target DNA to the recovery rate. Results showed a recovery DNA efficiency of 7 55%. The recovery rate of DNA in a mixture with non-target DNA resulted in ~87%. In summary, a high amplification efficiency using real-time PCR was found, for which estimated concentrations revealed cell numbers of 2.7 × 105 cells m-3 in bioaerosol and 2.8 × 106 cells g-1 fw-1 in material samples from a duck house. The specificity of the new developed quantification system was shown by generation of two clone libraries from bioarosol samples, from a duck house, and from a composting plant. Totally, the results clearly show the specificity and practicability of the established qPCR assay for detection of S. rectivirgula.
