This paper aims to examine whether consumers’ appreciation of promotional gifts exceeds firms’ cost of providing these gifts. The paper also compares characteristics of appreciated and unappreciated gifts.

The authors surveyed 1,289 college students in five European countries. The authors use willingness to accept cash (WTA) for an item to assess consumers’ appreciation of promotional gifts. They then compare WTA to firms’ estimated cost of providing the gifts.

On average, consumers’ appreciation of promotional gifts is 2.4 times the estimated cost of these gifts to sellers. Appreciated gifts tend to be less costly, tend to accompany more expensive purchased items and are more likely to complement these items. The results also reveal that more expensive items come with more costly gifts, although the gifts’ cost increases less than proportionally with the associated items’ price. The gift items are appreciated by men more than women.

This study enriches the literature on promotional gifting by introducing a simple measurement that can help firms decide whether to use gifts or discounts to promote their products.

Large supermarket chains are adopting customer-service robots to improve service delivery in physical stores. Successful deployment of these robots depends on shoppers' willingness to interact with them, requiring an understanding of influencing factors. This study, grounded in the Cognitive-Affective-Normative (CAN) theory, seeks to systematically explore the factors influencing Gen Z shoppers' willingness to interact with customer-service robots.

A hybrid approach combining Structural Equation Modeling (SEM) and Necessary Condition Analysis (NCA) was employed to analyze survey data collected from 945 Gen Zs in the Czech Republic.

The results from SEM highlight significant cognitive, normative, and affective factors that influence the intention of Gen Z shoppers to interact with a customer-service robot. Specifically, cognitive factors such as effort and performance expectancy, along with normative factors like subjective norms, emerged as critical determinants. Furthermore, affective factors such as technology anxiety and positive emotions significantly influence users' readiness to use customer-service robots for service requests. The study also underscores that positive emotions, effort expectancy, performance expectancy, and subjective norms are vital prerequisites for interacting with customer-service robots.

The originality of this work lies in its two significant contributions to the burgeoning field of SRs in retail literature. First, it extends the CAN theory to the context of SRs among Gen Z shoppers in Czechia, thereby enriching the existing literature on SRs in retail. Second, by employing a hybrid analytical approach, our research offers both empirical and methodological advancements, providing rigorous insights crucial for enhancing the understanding of the pivotal factors influencing shoppers' interactions with SRs in physical store environments.

In a conventional finite element analysis, material properties, dimensions and applied loads are usually defined as deterministic quantities. This simplifying assumption however, is not true in practical applications. Using statistics in engineering problems enables us to consider the effects of the input variables dispersion on the output parameters in an analysis. This provides a powerful tool for better decision making for more reliable design. In this paper, a probabilistic based design is presented which evaluates the sensitivity of a mechanical model to random input variables. To illustrate the effectiveness of this method, a simple bracket is analyzed for stress‐strain behavior using commercially available finite element software. Young’s modulus, applied pressure and dimensions are considered as random variables with Gaussian distribution and their effects on maximum stress and displacement is evaluated. The finite element results are compared with reliability based theoretical results which show very good agreement. This demonstrates the capability of commercially available software to handle probabilistic approach design.

Nobody concerned with political economy can neglect the history of economic doctrines. Structural changes in the economy and society influence economic thinking and, conversely, innovative thought structures and attitudes have almost always forced economic institutions and modes of behaviour to adjust. We learn from the history of economic doctrines how a particular theory emerged and whether, and in which environment, it could take root. We can see how a school evolves out of a common methodological perception and similar techniques of analysis, and how it has to establish itself. The interaction between unresolved problems on the one hand, and the search for better solutions or explanations on the other, leads to a change in paradigma and to the formation of new lines of reasoning. As long as the real world is subject to progress and change scientific search for explanation must out of necessity continue.

In the light of a resurgence of “evolutionary” research, sets out to raise some of the philosophical issues associated with an evolutionary conception of economics. Considers Tony Lawson′s work on transcendental realism as a point of departure in the building of an argument which promotes the adoption of a pluralist and holistic conception of economics. Suggests that, while Lawson′s transcendental realism has largely been developed independently of evolutionary economics, with the modifications outlined it may provide a suitable starting point for the formulation of philosophical foundations of evolutionary economics. Augments Lawson′s argument by the suggested adoption of an organic framework and the notion of types as the means of providing a base for the pluralist outlook of evolutionary economics.

Despite the widespread use of authentication schemes and the rapid emergence of novel authentication schemes, a general set of domain-specific guidelines has not yet been developed. This paper aims to present and explain a list of human-centered guidelines for developing usable authentication schemes.

The guidelines stem from research findings within the fields of psychology, human–computer interaction and information/computer science.

Instead of viewing users as the inevitable weak point in the authentication process, this study proposes that authentication interfaces be designed to take advantage of users’ natural abilities. This approach requires that one understands how interactions with authentication interfaces can be improved and what human capabilities can be exploited. A list of six guidelines that designers ought to consider when developing a new usable authentication scheme has been presented.

This consolidated list of usable authentication guidelines provides system developers with immediate access to common design issues impacting usability. These guidelines ought to assist designers in producing more secure products in fewer costly development cycles.

Cybersecurity research and development has mainly focused on technical solutions to increase security. However, the greatest weakness of many systems is the user. It is argued that authentication schemes with poor usability are inherently insecure, as users will inadvertently weaken the security in their efforts to use the system. The study proposes that designers need to consider the human factors that impact end-user behavior. Development from this perspective will address the greatest weakness in most security systems by increasing end-user compliance.

Attempts to trace the evolution of the major ideas of the natural law and in this way shed some light on the ethical contents of economics. Asks the reader to ponder some of the perennial questions such as: What is primary, ego or social association? Is man a social animal by nature? Is man a political animal? Is the justification for human existence to be found in the individual alone or in the social whole? Is society a synthesis of individuals, or does it contain something more than the simple totality of individuals?

This paper responds to recent calls for deeper scrutiny of the institutional contexts of citizen science. In the last few years, at least two dozen civil society organizations in New York and Pennsylvania have begun monitoring the watershed impacts of unconventional natural gas drilling, also known as “fracking.” This study examines the institutional logics that inform these citizen monitoring efforts and probes how relationships with academic science and the regulatory state affect the practices of citizen scientists. We find that the diverse practices of the organizations in the participatory water monitoring field are guided by logics of consciousness-raising, environmental policing, and science. Organizations that initiate monitoring projects typically attempt to combine two or more of these logics as they develop new practices in response to macro-level social and environmental changes. The dominant logic of the field remains unsettled, and many groups appear uncertain about whether and how their practices might have an influence. We conclude that the impacts of macro-level changes, such as the scientization of politics, the rise of neoliberal policy ideas, or even large-scale industrial transformations, are likely to be experienced in field-specific ways.

Looks at the reasons for the collapse of both regimes and considers the importance of repression with these developments. Contrasts the methods of Imperial Russia with the Bolsheviks looking at Court proceedings, prison conditions, education and propaganda in prison, exile and the secret police. Concludes that whilst social support is usually seen as essential for survival of a system, repression is not regarded as a positive element but can become the method for a system’s survival and stability.
