Wellbeing evaluation using ordered categorical response data is hazardous given the scale dependent nature of most measures of wellbeing and inequality. Here, scale independent instruments for measuring levels of wellbeing and inequalities between groups in multidimensional ordered categorical environments are introduced and applied in a study of health and consumption wellbeing and the aging process in twenty‐first century China. Urban/rural location, gender, age and the availability of welfare support were considered circumstances in what is in essence a study of equality of opportunity in the acquisition of health and consumption wellbeing in Chinas’ aging population. Older populations are found to experience diminished and increasingly diverse wellbeing outcomes that are, to some extent, ameliorated by welfare support.

This study aims to help develop “business principles for stakeholder capitalism” in two steps. First, the study defines internal logic of three theories of capitalism and two variants within each theory. Second, it examines approaches to integration into modern democratic capitalism. Treating the three theories as substitutes identifies relative strengths and weaknesses; complementarity and partial overlap approaches to integration study the institutional settings within which stakeholder capitalism operates. Empirical outcomes reflect competition between market and stakeholder businesses for participants, with institutional conditions determining the scope of collective action.

The approach aligns three typologies in a unique conceptual arrangement defining the three theories of capitalism: forms of capitalism, potential failures of each form and associated types of goods. The first method examines the internal logic of each theory of capitalism. The second draws on traditional narrative review of references documenting each theory of capitalism and variants together with modern Marxist anti-capitalism.

Three typologies align uniquely with the theories of capitalism, each having two variants. Both variants of stakeholder capitalism are compatible with compassionate capitalism, constitutional government or polycentric governance but not with self-interest capitalism, dictatorship or Marxism. A theory of modern democratic capitalism allocates roles for private, club and social goods with empirically variable mixes occurring across countries. Competition among different types of enterprises provides an empirical test for comparative advantages of stakeholder capitalism. Future research should consider approaches for testing the proposed conceptual scheme in practice concerning capacity to deal with grand challenges, wicked problems and black swan events.

Research approach is limited to logical examination of theories and literature documentation without direct empirical confirmation. The study does not address practical implications for managers and public officials or social implications concerning private incentives, stakeholder cooperation or collective action.

Originality lies in shifting terms of debate about stakeholder capitalism from advocacy of substitute theories to understanding of its relationship to market capitalism and collective action capitalism. Value lies in explaining desirability of theoretical integration of three types of capitalism into a comprehensive framework for modern democratic capitalism.

The purpose of this paper is to examine the effect of peer pressure on joint consumption decisions among emerging adults. Building on prospect theory and characteristics of emerging adulthood, the authors propose that influence from peers (i.e. informational and normative influence) serves as a channel to understand how peer pressure shapes joint consumer behaviors at different levels of social capital.

An online survey is distributed to the emerging adults, aged 18 to 25, in the south, west, east and middle of the USA. Construct validity and reliability are tested by using confirmatory factor analysis. Structural equation modeling is used to test the mediating and moderating effects.

The results show that social capital moderates the relationship between peer pressure and group-oriented consumer decisions, such that the relationship is positive in groups with high-level social capital but negative in groups with low-level social capital. Furthermore, such effects tend to be achieved via peer influence. And peer influence is stronger in groups with high-level social capital than those with low-level social capital.

The current literature has shown contradictory results: it is usually believed that emerging adults may conform to pressure and engage in group-oriented decisions; however, some research has reported the opposite result. To better understand this relationship, the authors aim at a group-level factor – perceived social capital – as a boundary condition. This research contributes to the young consumer decision-making literature by involving the interplay among peer pressure, perceived social capital and peer informational and normative influence.

This study aims to develop a new general framework of the challenges for decision making in groups. Unlike most research focused on individual consumption, this study takes a broader perspective on joint consumption.

The conceptual framework and the developed research questions are based on an extensive literature review.

This research identifies five major challenges for group decisions: allocation of responsibilities, preference prediction, preference aggregation, conflicts and mutual influences. For each challenge, this study summarizes existing findings and highlights important areas for continued investigation, related to a marketing-oriented understanding of consumers. This article concludes with implications for both managers and researchers.

The identified key determinants of group decisions aggregate findings from multidisciplinary literature and can help marketing researchers and managers understand the relevant but underresearched issues of decision making in groups. Furthermore, this study includes relevant moderators, such as individual and group characteristics, and reveals problematic research gaps. In turn, it offers questions and ideas for additional research.

This study aims to assess the potency and dose of Δ-9-Tetrahidrocannabinol (THC) and Cannabidiol (CBD) in cannabis joints. This will enable better estimates of the degree of exposure in a user and contribute towards a better understanding of potential harmful effects.

Analysis of intact joints confiscated by law enforcement on the street in the autonomous region of Castilla y León (Spain) during the years 2017–2019.

This study analysed THC, CBN and CBD in marijuana joints (N = 744). Joints contain cannabis and tobacco (N = 729), had a median net weight 0.69 g (IQR = 0.28); concentration THC median was 6.30%(IQR = 4.51) and THC median dose 42 mg (IQR = 32.75). A total of 35.5% mixed joints contained CBN – median percentage 0.61% (IQR = 0.51). CBD was detected 10.3% of mixed joints – median percentage 0.13% (IQR = 0.12) and median dose 1 mg (IQR = 0.92). CBD/THC ratio presented median value of 0.02 (IQR = 0.02). The samples analysed comprised pure cannabis joints (N = 15), with THC median 11.86% (IWR = 6.30) or median dose of 118 mg.

The study found high values for concentration and dose of THC and CBD in cannabis joints, warning of high exposures for the user and associated potential consequences. The results obtained contribute new perspectives on the definition of a standard cannabis unit.

The purposes of this research are to examine the extent to which daughters view their mothers as consumption role models, the extent to which daughters serve as consumption role models for their mothers, and the extent to which external role models are shared by mothers and their adolescent daughters.

Two qualitative studies focused on mothers‐adolescent daughters‐vicarious role models interactions as drivers of consumption behaviors in Western cultures. Study 1 included 20 in‐depth interviews with mothers and their adolescent daughters (conducted separately). Study 2 included five of the original dyads interviewed jointly and observed in fashion stores.

Regarding adolescent daughters' use as role models and fashion markers for their mothers, most mothers confirmed that their adolescent daughters' fashion opinion was very important. Second, based on consumer socialization arguments, mothers served as role models for their adolescent daughters. Most dyads shop for fashion items together and in the same stores. Regarding the issue of cognitive versus chronological ages, the studies suggest that there is a gap between mothers' cognitive and chronological ages in support of cognitive age theory and the youthfulness ideal of Western cultures. Notably, such a gap mostly failed to materialize for adolescent daughters. Hence, consumption similarity appears to be driven more by the gap for mothers than the gap for daughters. Finally, external role models such as celebrities did not have a great influence on mothers or their adolescent daughters.

The research used in‐depth interviews with and in‐store observation of mothers and adolescent daughters. Future research might use similar interviews with younger daughters. Another extension of the work reported here that can provide triangulation for the findings is to change from a qualitative to a quantitative methodology.

Increasingly, consumers shopping online are not doing so alone. This paper aims to identify motivations for and barriers to shopping together with relatives or friends on the same screen.

This study proposes an interdisciplinary theoretical framework investigating “sharing” and related commercial practices. It adopts an exploratory qualitative methodology as the phenomenon of screen sharing has not been widely investigated in prior consumer behavior literature.

Social and utilitarian motives elicit joint shopping in stores and collaborative consumption. This study reveals a third motive, related to the need for control, that drives shopping on the same screen. Screen sharing can increase efficiency, social bonds and control, due to the transparent presentation of information on the screen, but it also can cause inefficiency, social tension and struggle for control over the device.

Screen-sharing motives reflect different logics for sharing: distribution (use with), communication (discuss with) and collaboration (control with). Defining further antecedents and consequences of joint shopping on the same screen represents relevant goals for further research.

By adapting their online platforms, brands can provide more agreeable, efficient and empowering experiences to screen-sharing shoppers, and thus gain competitive advantages.

Marketers generally assume online shoppers are alone at their screens, but in practice, many of them are often browsing together. Especially for families confined together at home, shopping together online constitutes a common practice.

This paper compares the socio-demographic features, wine consumption preferences and habits of individuals of Generations X and Y. The influence of age, as a life cycle effect, on individuals' consumption preferences from the same generation is analysed. In addition, the generational effect and period effect on consumption by each generation are studied to ascertain changes in preferences due to specific values of their birth cohort or period.

Mixed ordered logit models are estimated to identify which traits influence the probability of consuming a certain quantity of wine for each generation. The variability of the effects of different variables on the consumption decision is analysed in depth, as a reflection of the unobserved heterogeneity present in individuals' decisions. For this purpose, data from two exhaustive surveys carried out in Tenerife (Canary Islands) over a time interval of 13 years are used.

Individuals' age and period are relevant factors in the consumption decision. There are some similarities in the behaviour of both generations, although the variability of the effects of some individual traits is greater for Generation X.

This paper contributes to a better understanding of the profile of wine consumers from different generations through a joint analysis of age effects, period and cohort, which have rarely been addressed jointly in the literature. In addition, it provides an exhaustive analysis of the heterogeneity in consumption preferences that highlights the variability of the effects found.

This paper aims to investigate the influences of process parameters on part quality, electrical energy consumption. Moreover, the relationship between part quality and energy consumption of UTR9000 photosensitive resin fabricated by stereolithography apparatus (SLA) was also assessed.

Main effect plots and contour maps were used to analyze the interactions and effects of various parameters on energy consumption and part quality, respectively. Then, a growth rate was used defined as the percentage of the value of energy consumption (or the part quality) of the sample compared to the minimum value of the energy consumption (or the same part quality), to jointly analyze relationships between part quality and energy consumption on a specific process parameter.

The part qualities can be improved with increased energy consumption via adjusting layer thickness, without further increasing energy consumption through adjusting laser power, over-cure and scanning distance. Energy consumption can be highly saved while slightly decreasing the tensile strength by increasing layer thickness from 0.09 mm to 0.12 mm. Energy consumption and surface roughness can be decreased when setting laser power near 290 mW. Setting an appropriate over-cure of about 0.23 mm will improve tensile strength and dimensional accuracy with a little bit more energy consumption. The tensile strength increases nearby 5% at a scanning distance of 0.07 mm compared to that at a scanning distance of 0.1 mm while the energy consumption only increases by 1%.

In this research, energy consumption and multiple part quality for SLA are jointly analyzed first to accelerate the development of sustainable additive manufacturing. This can be used to assist designers to achieve energy-effective fabrication in the process design stage.

Lower‐limb exoskeletons and powered orthoses are external devices that assist patients with locomotive disorders to achieve correct limb movements. Current batteries cannot meet the long‐term power requirements for these devices, which operate for long periods of time. This issue has become a major challenge in the development of these portable robots. Conversely, legged locomotion in animals and humans is efficient; to emulate this behaviour, biomimetic actuation has been designed attempting to incorporate elements that resemble biological elements, such as tendons and muscles, in the mechanical systems. The purpose of this paper is to present a mechanism that resembles a human tendon to achieve and utilise the synergic actuation of the leg joints.

In this paper, we present a mechanism that resembles a human tendon to move the ankle joint and utilise the synergic actuation of hip and knee joints. Implementation of the proposed transmission system in the ATLAS active orthosis prototype allowed for a better ankle gait fit, which resulted in a more natural stride and, as expected, optimised energy consumption in the locomotion cycle and actuation energy requirements.

The fitted passive ankle motion provides toe‐off impulse, increases support force, and helps provide ground clearance.

A synergetic underactuated movement in the ankle joint, implemented by two cables in each leg, improves the functionality of the device without increasing the leg weight and while maintaining a reduced size. To achieve a correct and efficient motion in the ankle of an active orthosis, two steel cables were attached in the ATLAS orthosis. These cables act as a synergic biarticular linkage and transfer motion from the hip and knee joints. Synergic ankle motion provides impulse in the toe‐off, increases support force, and provides ground clearance. These goals are achieved with low energy expenditure because of synergical actuation, and high inertia is prevented in the more distal limb.
