This study aims to investigate the relationship between religiosity, belief in a just world (BJW), trust and affinity fraud.

Using an online panel vendor, this study collected survey data from 1,030 participants. Participants are balanced based on US Census data.

This study finds evidence that religiosity and, to a lesser extent, trust were correlated with choosing an affinity investor but not BJW. Overall, this study adds to the literature on fraud by examining the potential processes of tricking a victim.

This study examines the complex decision-making around investing with fraudsters. This study disentangles the relationship between affinity fraud, decision-making, trust and religiosity. Furthermore, this consider the reasons why a shared affinity may increase trust through the lens of the decision-maker.

Food waste, a global conundrum with adverse socioeconomic and environmental implications, occurs when more money is spent on food during occasions akin to Ramadan. This study examines the moderating role of antecedents (festive experience, nostalgic food memory, perceived scarcity, and religiosity) to understand the impacts of excessive food buying on Ramadan food waste.

A cross-sectional survey was performed with a self-administered questionnaire using Google Forms to gather data on social media. Notably, 349 valid responses were analysed via Partial Least Squares Structural Equation Modelling (PLS-SEM) with SmartPLS 4 for model development and hypothesis testing.

Festive experience, nostalgic memory, and perceived food scarcity could explain excessive buying behaviour. In this vein, excessive food buying contributed to Ramadan food waste. Meanwhile, religiosity was found to moderate excessive food-buying behaviour.

The empirical findings offered useful insights for practitioners and policymakers to implement optimal marketing strategies and interventions that improve responsible consumption and minimise food waste.

This study provided a sound understanding of consumer buying behaviour during Ramadan regarding food waste and overconsumption. The current work delineated the role of descriptive, injunctive norms and cognitive dissonance in shaping buying behaviour during Ramadan.

Identification of the direction of the sound source is very important for human–machine interfacing in the applications such as target detection on military applications and wildlife conservation. Considering its vast applications, this study aims to design, simulate, fabricate and test a bidirectional acoustic sensor having two cantilever structures coated with piezoresistive material for sensing has been designed, simulated, fabricated and tested.

The structure is a piezoresistive acoustic pressure sensor, which consists of two Kapton diaphragms with four piezoresistors arranged in Wheatstone bridge arrangement. The applied acoustic pressure causes diaphragm deflection and stress in diaphragm hinge, which is sensed by the piezoresistors positioned on the diaphragm. The piezoresistive material such as carbon or graphene is deposited at maximum stress area. Furthermore, the Wheatstone bridge arrangement has been formed to sense the change in resistance resulting into imbalanced bridge and two cantilever structures add directional properties to the acoustic sensor. The structure is designed, fabricated and tested and the dimensions of the structure are chosen to enable ease of fabrication without clean room facilities. This structure is tested with static and dynamic calibration for variation in resistance leading to bridge output voltage variation and directional properties.

This paper provides the experimental results that indicate sensor output variation in terms of a Wheatstone bridge output voltage from 0.45 V to 1.618 V for a variation in pressure from 0.59 mbar to 100 mbar. The device is also tested for directionality using vibration source and was found to respond as per the design.

The fabricated devices could not be tested for practical acoustic sources due to lack of facilities. They have been tested for a vibration source in place of acoustic source.

The piezoresistive bidirectional sensor can be used for detection of direction of the sound source.

In defense applications, it is important to detect the direction of the acoustic signal. This sensor is suited for such applications.

The present paper discusses a novel yet simple design of a cantilever beam-based bidirectional acoustic pressure sensor. This sensor fabrication does not require sophisticated cleanroom for fabrication and characterization facility for testing. The fabricated device has good repeatability and is able to detect the direction of the acoustic source in external environment.
