Effectiveness and context dependency of social norm interventions: five field experiments on nudging pro-environmental and pro-social behavior
(2024-06-26)
Social norm interventions hold the potential to change people’s behavior. Five field experiments (N = 1,163) examined the effects of a simple and easily realizable social norm nudge based on the social media format “Be like Bill.” The nudge consisted of a stick figure named Toni that communicated descriptive and injunctive norms regarding pro-environmental or pro-social behaviors. Nudge conditions were compared to no-intervention control conditions. Experiment 1 (N = 179) focused on paper towel consumption in a women’s ...

Pulsed Propulsion of Unmanned Aerial Vehicles by Centrifugal Force Modulation - First-Order Theory and Practicability
(2024-05-16)
A novel technique suitable for the propulsion of small unmanned aerial vehicles (UAV) is discussed in this paper. This approach utilizes the rotational energy of airborne gyro rotors and converts it into translational propulsion for the vehicle. The energy conversion is achieved by generating precisely directed centrifugal force pulses through short-duration rotor unbalances. The accurate control of the timing and magnitude of these unbalances is crucial for successful propulsion generation. Our first-order theory ...

Social drivers affecting job design in apparel supply chains: Inferences from a discrete choice experiment
(2024-02-23)
Because of increasing customer awareness and government regulations, apparel organisations are inclined to adopt social sustainability practices (SSPs) into their working environment. There is a lack of scientific literature examining the interaction between social and economic sustainability within the apparel industry from the employee perspective. This study aims to assess the preferences of blue and white-collar employees in the apparel supply chain to implement SSPs. The SSPs were identified through a literature ...

FTIR spectroscopy and multivariate discriminant analysis for classifying bituminous mastics: Exploring aging states and mastic composition
(2024-07-02)
This study aimed to differentiate among various bituminous mastics through the analysis of FTIR spectroscopy data. The mastics, incorporating three filler types, a 50/70 penetration index binder, and foamed bitumen, underwent chemical examination via FTIR spectroscopy after exposure to various aging cycles. Employing different multivariate discriminant analysis approaches, the investigation identified an optimal method, i.e., PLSR-LDA, which achieved a prediction precision of 100 % in distinguishing between various ...

Seasonal variation in heavy metal intake and excretion by dairy cattle in an Indian megacity
(2024-06-10)
Milk consumption plays a pivotal role in human nutrition, especially for children, due to its high protein, calcium, and vitamin contents that aid cognitive development. Nonetheless, potential hazards from heavy metal presence in milk, due to environmental exposure and intake through feed, have gained global attention. Given paucity of data we investigated the seasonal variation in the quantitative intake of heavy metals (cadmium: Cd, chromium: Cr, lead: Pb) by dairy cows in the South Indian megacity of Bengaluru, ...

Susceptibility of a Fe-Mn-Al-Ni-Cr shape memory alloy to environment-assisted corrosion cracking
(2024-06-20)
In recent years, iron-based shape memory alloys (SMAs) have become increasingly interesting for application in civil engineering structures. Promising candidates in the field are iron-based Fe-Mn-Al-Ni-X (X = Ti, Cr) SMAs. These alloys have demonstrated the potential to be used in various types of applications. While the fully recoverable martensitic phase transformation can be used for structures where high damping capacities are required, i.e. for high rise buildings in earthquake prone areas, it has been successfully ...

Presence of keel bone damage in laying hens, pullets and roosters of local chicken breeds
(2024-01-26)
In commercial laying hens, keel bone damage (KBD) is a severe health and welfare problem leading to pain, reduced mobility and decreased laying performance. Flocks of all production systems and hybrid lines can be affected. KBD is a multifactorial welfare issue and, among other factors, associated with a high laying performance which negatively affects the calcium deposit in the medullary bones. Therefore, mature hens of local breeds with much lower egg production than commercial hybrids may be expected to show less ...

Controlled Ring Opening of a Tetracyclic Tetraphosphane with Twofold Metallocene Bridging
(2024-02-19)
A direct route to a doubly ferrocene bridged tetracyclic tetraphosphane 1 was developed via reductive coupling of Fe(CpPCl₂)₂ (2 a), where a chlorine terminated linear P₄-compound 3 could be identified as an intermediate. Selective P−P bond activation was further achieved by reacting 1 with elemental selenium or [Cp*Al]₄, where regioselective insertion of Se or Al atoms resulted in ferrocenylene bridged [P₄Se] (4) or [P₄Al] (7) moieties. Compound 7 can be transformed to a hydrogen terminated linear P₄ species, 8, ...

Does intense tax competition boost public acceptance for inter-municipal cooperation? Evidence from a survey among German citizens and local politicians
(2024-03-28)
Intense tax competition among local governments limits their potential for tax revenues. Inter-municipal cooperation (IMC) in general and joint business parks in particular constitute a platform to coordinate local tax rates with neighboring municipalities to reduce tax competition. We ask whether local politicians and citizens are aware of this logic and whether they account for it. Using survey data from German municipalities, we find citizens’ support for joint business parks to increase in the intensity of tax ...

Klarifizieren und Konfrontieren – oder besser doch nicht?
(2024-03-01)
Wenn wir über das Verschieben des Sagbaren sprechen, dann geht es auch um Selbstreflexion: Wo zensieren wir uns selbst und haben unseren Anteil daran, dass zentrale Inhalte aus dem Beratungskontext exkommuniziert werden? In arbeitsweltlichen Kontexten stellt sich immer wieder die Frage, wie ich meine Gegenübertragungs-Phänomene nutze, wenn ich ihrer überhaupt gewahr werde. Der Beitrag stellt an vier Beispielen gelungene und weniger geglückte Konfrontationen dar und stellt Überlegungen an, wie konstruktive Klarifikation ...
