A Study of Extensions of Classical Summation Theorems for the Series ₃F₂ and ₄F₃ with Applications
(2021-03-16)
Very recently, Masjed-Jamei & Koepf [Some summation theorems for generalized hypergeometric functions, Axioms, 2018, 7, 38, 10.3390/axioms 7020038] established some summation theorems for the generalized hypergeometric functions. The aim of this paper is to establish extensions of some of their summation theorems in the most general form. As an application, several Eulerian-type and Laplace-type integrals have also been given. Results earlier obtained by Jun et al. and Koepf et al. follow special cases of our main findings.

Does social exclusion improve detection of real and fake smiles? A replication study
(2021-01-28)
Research on social exclusion suggests an increased attention of excluded persons to subtle social cues. In one study (N = 32), published in Psychological Science,Bernstein et al. (2008) provided evidence for this idea by showing that participants in the social exclusion condition were better in correctly categorizing a target person’s smile as real or fake. Although highly cited, this finding has never been directly replicated.
The present study aimed to fill that gap. 201 participants (79.1% female) were randomly ...

Bygones in a public project
(2021-03-10)
The experimental literature suggests that contributions to a public good made dynamically, over multiple stages are higher than contributions made in a static setting, even when players do not receive feedback about co-players’ previous contributions between stages. Because the dynamic setting without feedback is strategically equivalent to the static one, this finding is puzzling. One important difference between the two settings, however, is that the dynamic setting gives the opportunity to sink contributions while ...

Quo Vadis Conferences in the Business and Information Systems Engineering (BISE) Community After Covid
(2021-07-06)
The global Covid-19 pandemic has not only influenced the way we work and collaborate on our research but also how we present and exchange novel contributions at scientific conferences. Governmental lockdowns and (inter)-national travel restrictions have forced conference organizers to move from offline conference venues to virtual platforms quickly. Our discipline, the Business & Information Systems Engineering (BISE) community, is an interdisciplinary field involving the more conference-driven computer sciences and ...

Evaluation of extremely steep residual stress gradients based on a combined approach using laboratory-scale equipment
(2021-11-30)
Surface treatments characterized by rapid heating and cooling (e.g. laser hardening) can induce very steep residual stress gradients in the direct vicinity of the area being treated. These gradients cannot be characterized with sufficient accuracy by means of the classical sin2Ψ approach applying angle-dispersive X-ray diffraction. This can be mainly attributed to limitations of the material removal method. In order to resolve residual stress gradients in these regions without affecting the residual stress equilibrium, ...

Augmented-Reality-basierte Assistenz für das Anlernen manueller und roboterunterstützter Montageprozesse
(2021-10-14)
Durch eine zunehmend flexibilisierte Produktion und relativ hohe Personalfluktuation bei einfachen Tätigkeiten wird das Anlernen neuer Mitarbeitender bzw. für neue oder geänderte Produktionsprozesse zunehmend relevanter. Konventionelle Anlernmethoden, bspw. durch Demonstration oder Arbeitspläne, haben Schwächen (bspw. binden sie zusätzliche Arbeitskraft oder sind kognitiv anspruchsvoll), die durch ein Augmented-Reality-(AR-)basiertes Assistenzsystem kompensiert werden können. Ein AR-Assistenzsystem zum Anlernen eines ...

Distributed Energy Balance Flux Modelling of Mass Balances in the Artesonraju Glacier and Discharge in the Basin of Artesoncocha, Cordillera Blanca, Peru
(2021-09-17)
A distributed energy balance model (DEBAM) is applied to estimate the mass balance of the Artesonraju glacier in the Cordillera Blanca (CB), Peru, and to simulate the ensuing discharge into its respective basin, Artesoncocha. The energy balance model calibrations show that, by using seasonal albedos, reasonable results for mass balances and discharge can be obtained, as witnessed by annually aggregated Nash Sutcliffe coefficients (E) of 0.60–0.87 for discharge and of 0.58–0.71 for mass measurements carried out in the ...

Heavy Metal Levels in Milk and Cheese Produced in the Kvemo Kartli Region, Georgia
(2021-09-21)
Milk and dairy products are among the most important food sectors in Georgia, and milk is considered one of the most essential foods in the human diet according to Georgian food culture. Kvemo Kartli is one of the major regions in Georgia for milk production. This region suffers from heavy metal contamination in soil and water because of the mining industry. This study was conducted to determine the concentrations of cadmium, lead, iron, zinc, copper, chromium, manganese, cobalt, nickel, selenium and molybdenum in ...

Deutungen: eine qualitative Studie unmittelbarer Patientenreaktionen
(2021-04-22)
Klassische psychoanalytische Deutungen stießen in den letzten Jahren vermehrt auf Kritik: Demnach würden diese Deutungen der therapeutischen Beziehung schaden, Blockaden auslösen und mit einer problematischen therapeutischen Haltung einhergehen. Anhand der Tonbandaufnahmen von 35 psychoanalytischen Sitzungen im mittleren Behandlungsverlauf, die im Rahmen der Münchner Psychotherapiestudie aufgezeichnet wurden, wurden 23 klassische Deutungen in 16 Sitzungen identifiziert und die Reaktionen der Patientinnen und Patienten ...

Freundschaften, Symmetrien und Markierungen von Differenz
(2021-06-03)
Der folgende Beitrag nimmt ausgehend von einem Forschungsvorhaben, welches Kinder als ‚Stakeholder‘ in Kindertageseinrichtungen adressiert, in den Blick, wie Kinder im Kontext institutioneller Arrangements Peer- und Freundschaftsbeziehungen zum Thema machen. Es zeigt sich, dass die Formen der Thematisierung von verbindlichen „Wir“-Erzählungen bis zu komplexen, asymmetrischen Beziehungserfahrungen reichen.
