The purpose of this paper is to differentiate human responses to different light switch designs to determine the effects of these common interfaces on user perceptions and use of electric lighting in public buildings.

Empirical studies were conducted to assess and examine user perceptions with regard to design characteristics of light switches, and occupants’ use of electric lighting was examined through field observations made in a public toilet.

The results point to the possibility of identifying characteristics of light switches that attract user attention and thereby encourage energy-saving behaviour in public buildings. A light switch perceived as simple but oversized affected occupants to turn off the lights more frequently when leaving the space under study as compared to switches of normal size.

Information on user perceptions of light switches may be limited by the assessments being carried out only in controlled environments. Assessing user perceptions in field observations is thus desirable, as it will provide more information on the perceptions in actual settings.

Effective design of user interfaces could provide a means of lowering energy use from electric lighting by affecting the behaviour of users. Using user perceptions to define critical design characteristics could contribute to design improvements in the interfaces with respect to users’ viewpoints.

This paper contributes to the subject with a basic, field-based approach to formulating an understanding of how design via user perceptions may encourage energy-saving behaviour.

The purpose of this study is to investigate the influence of surface texture on the subsurface characteristics of contact interfaces under elastohydrodynamic lubrication condition. As a typical contact form of gears and bearings, the optimization of friction characteristics at the elastohydrodynamic lubrication (EHL) interface has attracted the attention of scholars. Laser surface texturing is a feasible optimization solution, but there have been concerns about whether the surface texture of high-pair parts will affect their fatigue life.

To examine the impact of texture preparation on the subsurface characteristics of high-pair interfaces under EHL conditions, a point contact EHL model is developed that takes into account the effect of textured surface topography. The pressure and thickness of the oil film are calculated as input parameters under different loads and entrainment velocities. The finite element method is used to simulate the impact of textures with varying diameters, densities and depths on the subsurface characteristics of the elastohydrodynamic interface. According to ISO 25178, analyze the relationship between 3D topography parameters and subsurface characteristics and study the trend of friction characteristics and subsurface characteristics based on the results of the ball on disc friction tests.

The outcomes suggest that under different rotational velocity and load conditions, the textured surfaces exhibit improved friction reduction effects; however, the creation of textures can result in significant subsurface plastic deformation and local peeling. The existence of texture makes the larger stress zone in the subsurface layer closer to the surface, leading to fatigue failure near the surface. Reasonable design parameters can help enhance the attributes of the subsurface. A smaller Sa and a Str greater than 0.5 can achieve ideal subsurface properties on the textured surface.

This paper investigates the influence of surface texture on the friction and subsurface characteristics of EHL interfaces and analyzes the impact of surface texture on interface contact performance while achieving lubrication improvement functional characteristics. The results provide theoretical support for the optimization design and functional regulation of surface texture in EHL interfaces.

This study applies a product centric view to examine three product development (PD) decisions that relate to a new product and its supply chain (SC): product design, sourcing strategy and product delivery strategy (PDS). The purpose of this paper is to expand the understanding of alignment decisions in this area to include concurrent compatibility between product design, SC strategy and market conditions.

The study leverages existing theory to identify the key dimensions of alignment between product design, SC strategy and market conditions in a conceptual model. Using survey data from 124 new PD projects collected from various industries, the authors then empirically test the impact of multiple alignment decisions on new product introductions (NPIs) performance.

The results suggest that one specific project-level design parameter (interface intensity) is a key alignment dimension for product design decisions. Specifically, the authors find that alignment between interface intensity and sourcing strategy, as well as between interface intensity and clock-speed improves NPI performance. Additionally, the authors find evidence that three-way alignment between PDS, interface intensity and market volatility will benefit NPI performance.

Because the study is cross-sectional and conducted at the project level, future work should continue this line of inquiry with longitudinal exams and across a families of development projects.

The findings inform the deliberate management of the PD/SC interface and provide managers with quantitative benefits of concurrent alignment decisions.

This study identifies and addresses important deficits in the understanding of concurrent alignment between product design, SC strategy and market conditions.

The purpose of this paper is to characterize the interfaces between manufacturing companies and the Internet of Things (IoT) suppliers involved in their digital servitization.

This paper builds on an explorative case study of a manufacturing firm and its IoT suppliers. This paper relies on the Industrial Network Approach to study interfaces between buying firms and their suppliers.

This paper identifies three distinct types of supplier interfaces: connected, digital and digital-physical. They all contain technical resource interfaces with additional organizational and/or technical complexities that need to be managed. Connectivity, an Agile approach to software development and strong technical dependence emerged as key factors that impact the interactions between manufacturing firms and IoT suppliers and how their resources are combined.

This paper offers managerial implications regarding the importance of internal organization (such as appropriate cross-functional teams) to manage the dynamics of collaborations required by digital technologies, maintain interactions with IoT suppliers and identify and manage interdependences between IoT suppliers. Building close relationships with suppliers of crucial infrastructure (e.g. IoT cloud platform and data security systems) can also be beneficial for manufacturing firms to reduce risks. Finally, attention should be given to IoT technology strategy, which impacts both digital and digital-physical supplier interfaces.

In digital servitization, manufacturing firms are heavily reliant on external resources for IoT technology. Despite this, few studies have investigated the characteristics of their interfaces with IoT suppliers, how these can be managed and how resources are combined.

The purpose of this paper is to investigate supplier interfaces in technological development.

The theoretical framework is based on the industrial network approach and, in particular, the concept of supplier interfaces (standardized, specified, translational and interactive). The empirical study consists of a case study of a supplier relationship between an established truck manufacturer and one of its partners in technological development. This supplier relationship has its base in joint projects on developments in automation.

The empirical study provides evidence of three types of interfaces that are characteristic of technological development and discusses their development and how they are used in combination. The three types are follows: specified, translational and interactive. The conclusions show that developing an interface from specified to translational or interactive is challenging and technological development characterized by uncertainty may call for certain interfaces that are not of value in other settings, such as industrial production.

By applying the interface concepts to technological development in collaboration with suppliers and related identifying characteristic interfaces, this paper aims to extend the literature on how suppliers can be engaged in uncertain endeavours such as development projects.

In high-pressure pumps, due to the interaction of asperities on the upper and lower surfaces, the piston–cylinder interface suffers severe lubrication and sealing problems during mixed lubrication. This study aims to establish a mixed thermo-elastohydrodynamic (EHD) model for the lubrication gap to determine how working conditions affect the lubricating characteristics and sealing performance of the interface.

A mixed thermo-EHD lubrication model is established to investigate the lubricating characteristics and sealing performance of the interface between the piston and cylinder. The model considers piston tilting, thermal effect, surface roughness and bushing deformation. The interface lubricating characteristics and sealing performance under different working conditions are calculated by the proposed numerical model.

A higher inlet pressure contributes to an increase in the minimum film thickness. Increased shaft speed can significantly reduce the minimum film thickness, resulting in severe wear. Compared to roughness, the impact of the thermal effect on the interface sealing performance is more significant.

The proposed lubrication model in this study offers a theoretical framework to evaluate the lubricating characteristics and sealing performance at the lubrication gap. Furthermore, the results provide references for properly selecting piston-cylinder surface processing parameters.

Aims to present a comparison and evaluation of four user interfaces of web‐based e‐journals (Science Direct, ProQuest Direct, EBSCO Host and Emerald).

The systems were assessed in an expert study according to accepted guidelines regarding user friendliness and functionality. User friendliness features studied were: language(s) and type(s) of interface; navigation options; personalization; and screen features. Functions inspected were: database selection; query formulation and reformulation; results manipulation; and help.

Many similarities were found, but some differences among the systems were also discovered and analysed in detail. The greatest differences were found in the area of query formulation, and between the interface languages and types.

The user interfaces of four full‐text IR systems offering e‐journals which are accessible at the University of Ljubljana are surveyed.

The interfaces are surveyed and assessed in order to discover their characteristics, advantages, and potential downsides and/or mistakes which may hinder use by an average user.

The study serves as a basis for a subsequent user study of the information behaviour of the users of these systems.

This paper aims to investigate how various organizational interfaces between firms, units and functions, and the interplay between them, are developed and mobilized in product development processes.

The theoretical framework is based on the industrial network approach, including interactive resource development and the concept of organizational interfaces. A single case study is conducted at a world-leading industrial tool manufacturer, illustrating how resources are combined over time, crossing boundaries of firms, units and functions in the development of a hand-held digitalized tool for quality assurance in the production of cars. Data have been collected through semi-structured interviews, with additional data in the form of project reports, internal documents and practices for external collaboration.

In addition to inter-organizational interfaces, the study identifies a typology of scouting, embarking and integration interfaces at unit level (geographically spread units of one multinational corporation) and interpretation and reciprocal interfaces at function level. The conclusions show that these interfaces affect the outcome of three aspects of the product development process: product characteristics and functionality features, system integration and organizational network extent. Existing interfaces serve as a platform for developing interaction further and provide the interfaces with new content, thus moving between different types of interfaces. Product development processes also involve new interfaces where there was no previous interaction between the parties.

This research has implications for the interplay between interfaces in cases involving multiple external and internal actors in resource combining efforts.

External interactions between firms influence and impact internal activities and resources. Managers need to be aware of the complex interdependencies between external and internal interfaces and resources. Managing organizational interfaces is about both exploiting established interfaces and developing new ones. Consequently, existing interfaces may be activated differently to align with new interaction purposes, which, in turn, requires efforts to combine resources according to the new conditions.

Previous research contains a typology of organizational interfaces between customers and suppliers. The study expands on this research by identifying internal interfaces between units and functions.

Collaborations between public administrations and private sector represent a specific challenge to manage contractual and organizational relationships among partners with different goals, working cultures, norms, rules and processes. Therefore, the main research question of this paper is: What are the antecedents of effective collaboration in public-private IT outsourcing relations? Thus, the purpose of this paper is to identify the determinants of collaborative interface characteristics as scaffolding structures to manage public-private IT outsourcing relations effectively.

Two cases of public-private IT outsourcing relationships in Mexico were used to compare and contrast the main antecedents of collaborative interface characteristics. Case selection was based on the success in each case, as perceived by the collaborating members involved. A successful case and a less successful case of application development for the provision of public services from two state administrations in Mexico were chosen. Data gathering took place via face-to-face interviews.

The quality of the organizational interface depends on the interactions between exchange of knowledge and mutual trust, along with the commitment between partners. Trust, commitment and knowledge sharing interacted to enhance interface characteristics that have an impact on public and political values.

This paper used and extended an outsourcing technology enactment model to emphasize the quality of organizational interfaces as a main antecedent for the success of public-private IT outsourcing relations.

Effectively designing work practices and contracts implies the development of flexible contracts, objects and routines to adjust project requirements to fulfill better public-private goals. Such flexible contracts and practices are only possible in a trusting environment where participants shape their mutual understanding of the project.

The paper contributes to the literature on public-private IT outsourcing relationships by offering a theoretical framework on key antecedents and processes of success of these relationships.

The purpose of this study is to investigate the factors that influence the adoption of Higher Education Commission (HEC) National Digital Library among research students in different universities of Pakistan.

The study framework was based on technology acceptance model (TAM). A sample of Pakistani university students completed the questionnaire measuring the effects of extraneous stimuli through cognitive responses on adoption of the HEC digital library. To test the research hypotheses, multiple regression analysis was used.

The findings revealed that: cognitive responses predicted students’ intention of using HEC digital library; extraneous variables significantly influenced cognitive responses; system characteristics directly influenced usefulness and ease of use; interface characteristics directly influenced cognitive responses; and individual differences significantly affected the ease of use. Similarly, system quality was identified with the highest direct effect on usefulness, whereas navigation had the highest influence on easy use of the HEC digital library of Pakistan. In addition, usefulness was explored with the highest effect on intention to use the HEC digital library of Pakistan. The findings revealed that individual behaviours influence the use of digital libraries which imply that acceptance of an information system (IS) involve cognitive idiosyncrasies. Findings of the study are useful for Pakistani academic librarians to enhance adoption and usability of the HEC digital library of Pakistan. The study extended cross-cultural validation of TAM and explored how that Pakistani university students utilize HEC digital library.

These findings have significant implications for librarians in developing countries, such as to evaluate usability of digital libraries from individuals’ perspective, create awareness, customize users’ interface and train students in navigational techniques. It may also facilitate librarians to improve their current levels of library assistance and emphasize the usefulness of digital libraries towards academic excellence. The findings equally suggest that individual behaviours influence the use of digital libraries because acceptance of an information system involves cognitive idiosyncrasies. This study explored all possible links between the study constructs and emphasized that findings are useful to enhance the adoption and usability of digital library in the developing countries.

This study is the first attempt that empirically assessed the adoption of digital libraries in terms of Pakistani research students. The study validated TAM in the context of Pakistani university librarianship that extended the cross-cultural validation of TAM. Furthermore, the study focused on real constructs instead of dummy variables and predicted significant effects on acceptance and rejection of digital libraries.
