Differenzierung und Professionalisierung der personenbezogenen Beratungsformate
(2021-04-22)
Die Diskussion über den Stand der Professionalisierung und sowie über den Professionsanspruch personenbezogener Prozessberatung begleitet die fachliche Entwicklung der Beratung von ihren Anfängen an. Dabei hat sich diese Beratungsform inzwischen so erfolgreich etabliert, dass auch klassische Unternehmensberatungsfirmen, die ihre Dienstleistung vormals ausschließlich auf der Basis betriebswirtschaftlicher und juristischer Expertise anboten und großen Wert auf Distanz zu psychologisch orientierten Ansätzen legten, ...

Force distribution in self-tapping screws: experimental investigations with fibre Bragg grating measurement screws
(2021-08-17)
The pull-out resistance of fully threaded, self-tapping screws under axial loading has been investigated intensively in the past. Actual design models are based mainly on empirical data because the detailed interaction between the screw thread and the surrounding timber member remains unclear and might depend on the test set-up. An innovative screw sensor with 19 internal fibre Bragg gratings (FBGs) was developed to measure the forces along the screw axis. The screw diameter was 12 mm and the maximum embedding length ...

Ein achtsamer Blick auf den Achtsamkeits-Hype
(2020-01-23)
Achtsamkeit liegt sowohl in der psychologischen Forschung als auch in vielen gesellschaftlichen Bereichen im Trend. Dieser Artikel wirft einen achtsamen Blick auf den aktuellen Forschungsstand. Dabei werden zum einen diverse methodische Limitationen bei der empirischen Untersuchung von Achtsamkeit deutlich, wodurch valide Aussagen über tatsächliche Effekte nach wie vor nur begrenzt möglich sind. Zum anderen wird eine Forschungslücke bei möglichen unerwünschten Auswirkungen identifiziert. So sind negative Konsequenzen ...

Agile Erzählungen
(2022-01-05)
Wenn man sich mit dem Thema „Agilität“ inhaltlich befasst, erscheint es nicht angeraten, es in erster Linie als ein einheitliches theoretisches Konstrukt oder Modell zu betrachten, das man auf seine interne logische Stimmigkeit seiner einzelnen Bestandteile und auf deren empirische Verankerung hin überprüft. Damit würde man Kriterien anlegen, bei denen von vorneherein offensichtlich ist, dass der agile Ansatz dem weder gerecht werden kann noch will. Die eigentliche Bedeutung des agilen Konzepts liegt nicht in seiner ...

Diffusion of labor standards through supplier–subcontractor networks: An agent‐based model
(2020-06-22)
Subcontracting represents a popular business model in supply chains across industries. In the case of hidden subcontracting, subcontractors are beyond the visible horizon of the (focal) buying firm. Hence, buyers must rely on a cascading effect for diffusing practices such as compliance with labor standards through their supply networks. Motivated by the case of the Bangladeshi garment industry, we constructed an agent‐based model with buyers, first‐tier suppliers, and subcontractors as agents in a supply network in ...

Bottoms up: Delivering sustainable value in the base of the pyramid
(2020-01-24)
Despite a wealth of expertise involving leading institutions over at least 15 years, a base of the pyramid (BoP) model resulting in scalability has yet to emerge. We posit that institutional gaps between BoP goals of developing human and social capital on one hand and a short‐term profit focus of business on the other contribute to the lack of scalability. We address this gap by proposing a social intermediary to link the BoP with firms involved in the BoP. The social intermediary will coordinate and interpret the ...

Net Energy Balance and Fuel Quality of an Alley Cropping System Combining Grassland and Willow: Results of the 2nd Rotation
(2021-06-22)
With the central aim to reduce greenhouse gas emissions, agroforestry systems have become popular because they can provide biomass for bioenergy conversion and thus help replace fossil energy. This article compares the net energy balances of three biomass conversion techniques for an agroforestry system consisting of willows and two types of grassland biomass as well as separate stands of grassland and willow. The period of investigation was the second willow rotation (4–6 years after establishment). The biomass ...

Performance of Thermo-Mechanically Processed AA7075 Alloy at Elevated Temperatures—From Microstructure to Mechanical Properties
(2020-07-03)
This study focuses on the high temperature characteristics of thermo-mechanically processed AA7075 alloy. An integrated die forming process that combines solution heat treatment and hot forming at different temperatures was employed to process the AA7075 alloy. Low die temperature resulted in the fabrication of parts with higher strength, similar to that of T6 condition, while forming this alloy in the hot die led to the fabrication of more ductile parts. Isothermal uniaxial tensile tests in the temperature range of ...

Factors and Components Affecting Dairy Smallholder Farmers and the Local Value Chain— Kvemo Kartli as an Example
(2021-05-20)
Smallholder farmers are the cornerstone of the livestock sector and an essential element in building and developing the local dairy value chain, critical for developing its local economy. In Georgia, and despite the efforts made since independence from the Soviet Union until now, farmers still face many problems that prevent them from participating effectively in developing the dairy value chain, especially heavy metal pollution that afflicts the study region. This research study refers to smallholder farmers’ ...

Molecular Basis for Ser/Thr Specificity in PKA Signaling
(2020-06-25)
cAMP-dependent protein kinase (PKA) is the major receptor of the second messenger cAMP and a prototype for Ser/Thr-specific protein kinases. Although PKA strongly prefers serine over threonine substrates, little is known about the molecular basis of this substrate specificity. We employ classical enzyme kinetics and a surface plasmon resonance (SPR)-based method to analyze each step of the kinase reaction. In the absence of divalent metal ions and nucleotides, PKA binds serine (PKS) and threonine (PKT) substrates, ...
