The purpose of this article is to identify points of conceptual conflict between evidence‐based policy research and horizon (environmental) scanning.

The paper begins with a brief history of foresight in UK government, then describes the current government context for horizon scanning. Next, it defines horizon scanning as a method; highlights the contradictions between horizon scanning and more traditional empirical research; and offers suggestions to improve the rigor of horizon scanning.

Increased focus on defining the rules for source identification and scan data validation can enhance credibility.

Current horizon scanning work in the UK government suggests these methodological improvements, but proof will wait upon completion and deployment of several ongoing horizon scans.

Provides improved acceptability and dissemination of horizon scanning as a tool, as well as heightened engagement of policy‐makers, planners, and leaders with horizon scanning output.

There has been little previous work exploring the cultural constraints on adoption of horizon scanning within the evidence‐based polity context.

Many physically challenged users cannot interact with a computer through a conventional keyboard and mouse. They may interact with a computer through one or two switches with the help of a scanning mechanism. In this paper we present a new scanning technique based on clustering screen objects and then compare it with two other scanning systems by using a simulator. The analysis shows that the best scanning system is a type of block scanning that divides the screen in four equal sized partitions for four iterations and then switches to eight‐directional scanning. However, with a more accurate target acquisition process, the cluster scanning technique is found to outperform other scanning systems.

This paper aims to present a new input interaction system for people with severe disabilities. The new system works based on eye gaze tracking and single switch scanning interaction techniques. It combines eye gaze tracking and scanning in a unique way which is faster than only scanning‐based systems while more comfortable to use than only eye gaze tracking‐based systems, which is also supported by a user study.

The aim was to design a new interaction technique combining eye tracking and scanning technique for severely disabled people. A comparative study with eight users involving only an eye tracking system and the system combining eye tracking and scanning was conducted.

The participants rated the new system easier and less strenuous to use than the eye gaze tracking‐based system, while the new system did not slow the speed of interaction.

This new method based on eye gaze tracking and single switch scanning interaction techniques has potential to be a new interaction technique combining free source eye tracker and scanning switches. It is hoped users who can move a limb to use a single switch‐based scanning system will be hugely benefitted by this new system.

The purpose of this paper is to investigate the research approach to optimize shape accuracy, dimensional accuracy and density of customized orthodontic production fabricated by selective laser melting (SLM).

A series of process experiments were applied to fabricating customized brackets directly by SLM, using 316L stainless steel. Shape accuracy can be optimized through the study on fabricating characteristics of non‐support overhanging structure. A scanning strategy combining contour scanning with orthogonal scanning, which differ in scanning speed and spot compensations, was proposed to improve dimensional accuracy. Scanning laser surface re‐melting was added to enhance the SLM density.

Optimized SLM parameters lead to high shape precision of customized brackets, and the average size error of bracket slot is less than 10 μm. The customized brackets density is more than 99 per cent, and the surface quality and mechanical properties meet the requirements.

The paper presents the state of the art in SLM of customized production (especially medical appliances) by optimizing part properties. It is the first time that SLM is employed in the manufacturing of customized orthodontic products. It shows the original research on overhanging structure and compound scanning strategy, approach to optimize SLM part accuracy. An improved laser surface re‐melting is employed in the density optimization.

A study of ABB, Shell and CP Group of companies in Thailand found that the scope and management of environmental scanning activities within organizations evolve continuously as a result of volatility of the environment and the diverse nature of businesses. In the case of ABB and Shell the respective regional head office along with global head quarter participate actively in the process of environmental scanning in order to make strategic choices and grant approvals for operating budgets and new investments. The regional head quarter, in the case of ABB and Shell, plays the intervening role as information and capital resource provider whereas the country offices collect specific information at the industry and market levels and use it for implementing specific programs. In the case the of CP Group, the president and several vice presidents at the head office in Thailand play the bulk of the role in environmental scanning. All companies use business performance indicators to review the scope and the management of their environmental scanning practices.

This paper examines the connection between environmental scanning for market intelligence, organizational culture and generic strategies. The generic strategies, based on the Miles and Snow typology, are related to the organizational culture types developed by Deshpande et al. An enhanced model of the one proposed by Deshpande et al. is presented. By providing a more complete model, it is possible to more accurately represent an organization’s interaction with its environment with respect to its generic strategy and scanning approach. Propositions are presented pertaining to the type of scanning approach utilized by organizations in each quadrant. The paper concludes with planning implications for each quadrant.

Scanning projection-based stereolithography (SPSL) is a powerful technology for additive manufacturing with high resolution as well as large building area. However, the surface quality of stitching boundary in an SPSL system has been rarely studied, and no positive settlement was proposed to address the poor stitching quality. This paper aims to propose an approach of multi-pass scanning and a compensation algorithm for multi-pass scanning process to address the issue of poor stitching quality in SPSL systems.

The process of multi-pass scanning is realized by scanning regions repeatedly, and the regions can be cured simultaneously because of the very short repeat exposure time and very fast scanning. Then, the poor stitching quality caused by the non-simultaneous curing can be eliminated. Also, a compensation algorithm is designed for multi-pass scanning to reduce the stitching errors. The validity of multi-pass scanning is verified by curing depth test, while the performance of multi-pass scanning as well as proposed compensation algorithm is demonstrated by comparing with that of a previous SPSL system.

The results lead to a conclusion that multi-pass scanning with its compensation algorithm is an effective approach to improve the stitching quality of an SPSL system.

This study can provide advice for researchers to achieve the satisfactory surface finish with SPSL technology.

The authors proposed a process of multi-pass scanning as well as a compensation algorithm for SPSL additive manufacturing (system to improve the stitching quality, which has rarely been studied in previous work.

We report the findings from a study exploring the experiences of individuals undergoing MRI scanning for research. Semi‐structured interviews took place before and after scanning with 17 participants; 12 were healthy volunteers and five were patients with a diagnosis of remitted depression. Themes of apprehension and curiosity prior to scanning were common in both groups. Patients were often confused about the procedure. Negative feelings were an issue at the outset, characterised by shock related to the physical surroundings, after which positive feelings, for example relaxation, were often experienced, and in the case of patients, learning more about their brain. Written information about imaging was deemed satisfactory; however the ability to ‘experience’ aspects of scanning beforehand was suggested. Scanning may be viewed as a process beginning prior to the procedure itself and involving positive and negative emotions. Increased information, reassurance and a more interactive intervention to reduce anxiety may be beneficial and may improve individuals' experience of this widely used procedure.

While it is generally accepted that scanning supports organizational adaptation to the environment, scanning behavior may vary with the amount of environmental change. Information processing perspectives suggest that scanning activity will increase in response to increasing environmental uncertainty. Yet, social cognition perspectives suggest that scanning decreases at high and low levels of uncertainty since useful information is either unattainable or is already known. Using a combined perspective in a strategic decision‐making context, this study hypothesized that scanning would be greatest at high and low levels of uncertainty to support identification of previously unexploited niches. Results indicate that the level of environmental dynamism combined with the manager's functional position explains scanning behavior.

This paper aims to investigate two seminal market-scanning frameworks – the five-forces analysis and PESTEL environmental scanning tool – to assess their readiness for anticipating market-shaping acts.

Drawing on the market-shaping literature that conceptualizes markets as complex adaptive systems, this conceptual paper interrogates the underlying assumptions and “blind spots” in two seminal market-scanning frameworks. The paper showcases three illustrative vignettes in which non-industry actors catalyzed market change in ways that these market-scanning frameworks would not be able to anticipate.

Marketing strategists can be “blindsided” as seminal market-scanning frameworks have either too narrow an interpretation of market change or are too broad to anticipate specific types of market-shaping acts. The assumptions about markets that underpin these market-scanning frameworks contribute to incumbents being slow to realize market-shaping acts are taking place.

The authors extend market-scanning to include a type of managerial myopia that fails to register the socially embedded, systemic nature of complex contemporary markets. Furthermore, the paper provides an “actors-agendas-outcomes” scanning framework that offers awareness of market-shaping acts.

This paper is the first to consider market-scanning frameworks from a market-shaping perspective.
