Abstract
By tradition, sensors are used to measure one desired parameter; all other parameters influencing the sensor are considered as interfering inputs, to be eliminated if possible. Hence most of existing sensors are specifically intended for measuring one parameter, e.g. temperature, and the ideal temperature sensor should be as immune to all other parameters as possible. True, we sometimes use primitive sensor fusion, e.g. when calculating heat flow by combining separate measurements of temperature difference and of fluid flow.

Abstract
Worker classification continues to be a highly litigated area of taxation. That is, the status of a worker as an employee or independent contractor remains a topic closely scrutinized by the Internal Revenue Service. This study examines factors that the judiciary deems relevant in ruling whether a worker is an employee or independent contractor. A backward stepwise logistic regression model is implemented to categorize the factors that best predict the court’s decision on whether a worker is either an employee or independent contractor pursuant to the factors in Revenue Ruling 87-41 (1987-1 CB 296), judge gender, and political affiliation. The results indicate three factors (supervision/instructions, continuing relationship, and the right to discharge) are capable of accurately predicting 93 percent of the decisions made by the US Tax Court. Other findings support notable statistical differences between male and female judges rendering decisions and reaching conclusions. Also, there is a statistically significant difference based on the type of industry. Political affiliation appears to have no significant impact on judicial rulings.

Abstract
Purpose
The common language behind vernacular architecture only seems to be maintained in societies that preserve a traditional way of life. Changes in these societies can threaten their cultural heritage, while research may be a tool for its conservation and enhancement. In this paper, the habitat of a Mossi community is therefore studied as a first stage in analysing the possibilities of its maintenance.
Design/methodology/approach
After a previous study, data collection from a stay in Baasneere (Burkina Faso) and the analysis of 32 traditional residential units were completed. The research showed some common features which, when compared against the bibliography reviewed, could be defined as characteristic of the traditional architecture of this culture.
Findings
The home for a family unit consisted in an enclosure formed by the grouping of adobe constructions around a courtyard. As the family grew so did the compound, in a relationship directly linking the scales of architecture and the levels of kinship. The main daily activities took place in the courtyards while the individual interior spaces were understood as private shelters. Other typologies such as granaries, kitchens, warehouses and sheds were also analysed.
Originality/value
Some features of Mossi architecture already described in the existing bibliography were verified in the Baasneere case studies, showing that this tradition is still preserved. With a multidisciplinary approach, the house was examined not so much from the perspective of construction, but of its cultural configuration.

Abstract
Purpose
The objectives of the study, which focuses on reproductive health care services, are to identify factors that impede adequate access to care for migrant women and to identify possible solutions.
Design/methodology/approach
In this case study, problem‐based, semi‐structured individual interviews were conducted with 12 migrant women, eight staff members of non‐governmental organizations (NGOs), and eight staff members of a public hospital (physicians, nurses). The transcripts were analyzed using a grounded thematic approach.
Findings
Problems in access to services were identified in four areas: accessibility/information; institutional infrastructure; language barriers; and cultural competences.
Social implications
There is a need to develop culture‐specific understanding of health amongst service providers working in public hospitals. It is also necessary to raise awareness of traditional beliefs and behavior of migrant women to maximize good quality care. A closer collaboration of hospitals and NGOs is recommended, not least in order to ensure the demand‐ and needs‐orientation, appropriateness, effectiveness, and efficiency of health care for migrant women. Migrant women mentioned different approaches to delivering care – these solutions should, where possible, be applied in practice.
Originality/value
The study correlates and supports knowledge from existing literature regarding possible barriers to the use of health care services by women with migrant backgrounds. Recommendations for overcoming existing barriers are also identified by research participants.

Abstract
Purpose
This paper aims to design a novel hybrid terrestrial-aerial robot, FlyingDog, including its modeling and implementation. By combining the complementary advantages of a quadrotor drone and a quadruped robot, FlyingDog demonstrates excellent maneuverability and high energy efficiency, showcasing great potential for applications in industrial inspection, field exploration, and search and rescue operations.
Design/methodology/approach
By integrating propellers and leg mechanisms, FlyingDog achieves hybrid motion, encompassing both aerial flight and ground movement. This paper first provides an overview of the robot’s structural design, emphasizing the minimization of interactions between the aerial and ground mechanisms while balancing the thrust-to-weight ratio and payload capacity. A distributed control framework is then proposed to achieve the hybrid motion, alongside the development of corresponding control strategies to ensure stability during various movements.
Findings
Experiments conducted in real-world conditions validated FlyingDog’s performance in terms of motion stability, energy efficiency, and obstacle-crossing ability. The results demonstrate that FlyingDog exhibits outstanding mobility by combining ground locomotion with aerial flight capabilities, allowing it to overcome challenging obstacles in purely ground-based mode. In ground mode, the robot achieved an energy efficiency of up to 93.5%.
Originality/value
The hybrid terrestrial-aerial robot presented in this paper features stable land and aerial mobility, a lightweight structure, high energy efficiency, and low manufacturing costs, making it a valuable innovation in the field of robotics.

Abstract
Pew and Mavor (1998) called for an integrative representation of human behavior for use in models of individual combatants and organizations. Models with integrated representation of behavior have only been achieved at rudimentary levels according to those performing the studies (e.g. Pew & Mavor, 1998; Tulving, 2002) and those building the models (e.g. Warwick et al., 2002). This chapter will address aspects of cognitive performance that are important to incorporate into models of combat based on acceptance of theory, strength of empirical data, or for other reasons such as to bridge gaps where incomplete knowledge exists about cognitive behavior and performance. As a starting point, this chapter will assess which of Pew and Mavor’s recommendations are still appropriate as determined by a review of selected literature on cognition and its representation. We will also provide some review and extensions of key literature on cognition and modeling and suggest a way ahead to close the remaining gaps. Different aspects of cognition are described with recent findings, and most are followed by an example of how they have been represented in computer models or a discussion of challenges to their representation in modeling.
