Wine consumption is declining, while cannabis use among young adults in Germany has surged. With new laws partially legalising recreational cannabis, advocates claim it could replace alcohol, offering health benefits and cost savings. However, concerns remain that cannabis might increase alcohol consumption and associated health risks. Despite recognition of both substitute and complementary relationships between cannabis and alcohol, data on the cannabis–wine relationship is scarce. This study aims to understand the motivations behind wine and cannabis consumption, segment wine drinkers by those motives, profile wine drinkers who also consume cannabis and determine whether wine and cannabis act as substitutes or complements across distinct consumer groups.

The authors conducted an online survey using random sampling and used cluster analysis to identify consumer segments based on motivations for wine consumption. Exploring various variables, including consumption motives, behavioural patterns and socio-demographics, the authors also examined cannabis consumption among wine drinkers.

This study surveyed 523 German wine drinkers aged 20–60 years, including 215 cannabis users. Four consumer segments emerged: “adaptive conformists”, “expansive strategists”, “self-conscious hedonists” and “ambivalent drinkers.” Three segments preferred wine for social and enhancing effects. “Adaptive conformists”, the group with the most cannabis users, sought negative reinforcement like conformity or coping. The “adaptive conformists” and “expansive strategists” show the tendencies of a complementary cannabis–wine relationship.

This study pioneers the use of the Marijuana Motives Measure scales, developed by Simons et al. (1998), within the motivational framework by Cox and Klinger (1988) and Cooper et al. (2015), for wine drinkers. To the best of the authors’ knowledge, this is also the first to categorise wine drinkers into segments based on MMM scales for both wine and cannabis and segment wine consumers using cannabis.

The multiplicity of the late-night television offer is a recent phenomenon. In the late 1940s, TV was still in its experimental stage and programming was limited to certain hours of the day. How then did late-night evolve from one dominant program to the cornucopia that exists today? To what extent did the progressive fragmentation of the media environment contribute to this exponential growth in late-night programs? To answer these questions, this chapter will look closely at three phases of late-night history: the ascendance of The Tonight Show during the Johnny Carson era, Johnny's succession when two princes vied for his late-night throne, and then finally the latest developments where a new generation of late-night royalty, which I refer to as The House of Stewart, would emerge with a plethora of shows. Simultaneously, this chapter will also delve into the media context during each phase which became increasingly fragmented leading to an explosion of new ways of experiencing television.

High surface area-to-volume ratios make nanoparticles ideal for cancer heat therapy and targeted medication delivery. Moreover, ternary nanofluids (TNFs) may possess superior thermophysical properties compared to mono- and hybrid nanofluids due to their synergistic effects. In light of this information, the objective of this article is to examine the blood-based TNF flow within convergent/divergent channels under velocity slip and temperature jump.

Leading partial differential equations corresponding to the problem are transformed into a system of nonlinear ordinary differential equations by using similarity variables. The bvp4c code that uses the finite difference method is used to obtain a numerical solution.

The effect of nanoparticles may change depending on the characteristics of flow near the wall. The properties and proportions of the used nanoparticles become important to control the flow. When TNF was used, an increase in the Nusselt number between 4.75% and 6.10% was observed at low Reynolds numbers. At high Reynolds numbers, nanoparticles reduce the Nusselt number and skin friction coefficient values under some special flow conditions. Importantly, the effects of second-order slip on engineering parameters were also investigated. Furthermore, the Nusselt number increases with increasing shape factor.

Obtained results of the study can be beneficial in both nature and engineering, especially blood flow in veins.

The main innovations of this study are the usage of blood-based TNF and the examination of the effect of shape factor in convergent/divergent channels with second-order velocity slip.
