Abstract

Purpose

Displacement measurement in large-scale structures (such as excavation walls) is one of the most important applications of close-range photogrammetry, in which achieving high precision requires extracting and accurately matching local features from convergent images. The purpose of this study is to introduce a new multi-image pointing (MIP) algorithm is introduced based on the characteristics of the geometric model generated from the initial matching. This self-adaptive algorithm is used to correct and improve the accuracy of the extracted positions from local features in the convergent images.

Design/methodology/approach

In this paper, the new MIP algorithm based on the geometric characteristics of the model generated from the initial matching was introduced, which in a self-adaptive way corrected the extracted image coordinates. The unique characteristics of this proposed algorithm were that the position correction was accomplished with the help of continuous interaction between the 3D model coordinates and the image coordinates and that it had the least dependency on the geometric and radiometric nature of the images. After the initial feature extraction and implementation of the MIP algorithm, the image coordinates were ready for use in the displacement measurement process. The combined photogrammetry displacement adjustment (CPDA) algorithm was used for displacement measurement between two epochs. Micro-geodesy, target-based photogrammetry and the proposed MIP methods were used in a displacement measurement project for an excavation wall in the Velenjak area in Tehran, Iran, to evaluate the proposed algorithm performance. According to the results, the measurement accuracy of the point geo-coordinates of 8 mm and the displacement accuracy of 13 mm could be achieved using the MIP algorithm. In addition to the micro-geodesy method, the accuracy of the results was matched by the cracks created behind the project’s wall. Given the maximum allowable displacement limit of 4 cm in this project, the use of the MIP algorithm produced the required accuracy to determine the critical displacement in the project.

Findings

Evaluation of the results demonstrated that the accuracy of 8 mm in determining the position of the points on the feature and the accuracy of 13 mm in the displacement measurement of the excavation walls could be achieved using precise positioning of local features on images using the MIP algorithm.The proposed algorithm can be used in all applications that need to achieve high accuracy in determining the 3D coordinates of local features in close-range photogrammetry.

Originality/value

Some advantages of the proposed MIP photogrammetry algorithm, including the ease of obtaining observations and using local features on the structure in the images rather than installing the artificial targets, make it possible to effectively replace micro-geodesy and instrumentation methods. In addition, the proposed MIP method is superior to the target-based photogrammetric method because it does not need artificial target installation and protection. Moreover, in each photogrammetric application that needs to determine the exact point coordinates on the feature, the proposed algorithm can be very effective in providing the possibility to achieve the required accuracy according to the desired objectives.

Abstract

Purpose

Online social network (OSN) users have a high propensity to malware threats due to the trust and persuasive factors that underpin OSN models. The escalation of social engineering malware encourages a growing demand for end-user security awareness measures. The purpose of this paper is to take the theoretical cybersecurity awareness model TTAT-MIP and test its feasibility via a Facebook app, namely social network criminal (SNC).

Design/methodology/approach

The research employs a mixed-methods approach to evaluate the SNC app. A system usability scale measures the usability of SNC. Paired samples t-tests were administered to 40 participants to measure security awareness – before and after the intervention. Finally, 20 semi-structured interviews were deployed to obtain qualitative data about the usefulness of the App itself.

Findings

Results validate the effectiveness of OSN apps utilising a TTAT-MIP model – specifically the mass interpersonal persuasion (MIP) attributes. Using TTAT-MIP as a guidance, practitioners can develop security awareness systems that better leverage the intra-relationship model of OSNs.

Research limitations/implications

The primary limitation of this study is the experimental settings. Although the results testing the TTAT-MIP Facebook app are promising, these were set under experimental conditions.

Practical implications

SNC enable persuasive security behaviour amongst employees and avoid potential malware threats. SNC support consistent security awareness practices by the regular identification of new threats which may inspire the creation of new security awareness videos.

Social implications

The structure of OSNs is making it easier for malicious users to carry out their activities without the possibility of detection. By building a security awareness programme using the TTAT-MIP model, organisations can proactively manage security awareness.

Originality/value

Many security systems are cumbersome, inconsistent and non-specific. The outcome of this research provides organisations and security practitioners with a framework for designing and developing proactive and tailored security awareness systems.

Abstract

Purpose

The purpose of this paper is to propose a new approach for gauging the performance of the operating units of a retail banking organisation, responding to the special demands of an internal evaluation.

Design/methodology/approach

The paper defines a measure of internal performance (MIP) based on behavioural theory, particularly on disappointment models.

Findings

MIP is applied for the internal evaluation of a network of bank branches. Application to this real managerial setting reveals that bank managers' preferences support behavioural decision theory, including prospect theory.

Practical implications

The paper shows how MIP can be used as a management tool for improving organisational performance. The approach can be extended to other sectors.

Originality/value

The proposal differs from others existing in the literature in two main aspects. Firstly, it is consistent with the requirements of an internal evaluation because it uses the managers' real preferences instead of assuming them. Secondly, it takes into account that each unit has a different target to achieve according to its specific characteristics.

Abstract

Purpose

The complexity of the integration of non-financial benefits (NFB) in major infrastructure projects (MIP) engenders the formulation of networked knowledge between researchers and practitioners. The authors’ research question is as follows: To what extent does scientific knowledge about the integration of NFB into MIP support engaged scholarship or co-construction of knowledge between researchers and practitioners?

Design/methodology/approach

The paper uses a review of literature published in academic journals on the integration of NFB in MIP. Nearly 300 papers are analysed in depth, based on categories (aspects and sub-aspects) inspired from engaged scholarship and paradoxical participation approaches. The culture of collaboration and the notion of boundary objects are the two main aspects of this categorization of journal papers.

Findings

First, research on the integration of NFB into MIP is either project-oriented or society-oriented but in a larger proportion for society-oriented. Second, a lot of researches favour an analytic over a holistic approach, despite their openness to dialogue with practitioners through the complexity and conflict.

Practical implications

It contributes to the theorization of the engaged scholarship. It also provides insights about research avenues to be exploited where these aspects were not sufficiently exploited, as it is often the case with sustainability, for a better collaboration between researchers and practitioners. Linking the culture of collaboration, boundary objects and knowledge co-creation in the engaged scholarship setting encourages a better understanding of the needs (problem to be resolved) of practitioners, by themselves and the researchers.

Originality/value

The systematic review was conducted in parallel with the organization of two workshops with participants concerned by the integration of NFB into MIP. The paper identified four clusters from their level of compatibility with engaged scholarship.

Abstract

Purpose

The purpose of this study is to map the development of articles published, citations, and themes of Marketing Intelligence and Planning (MIP) over the 37-year period of 1983–2019.

Design/methodology/approach

This study uses the Scopus database to identify the most-cited MIP articles and most-included authors, institutions and countries in MIP. The study uses bibliometric indicators, as well as tools such as bibliographic coupling, performance analysis and science mapping, to analyze the publication and citation structure of MIP. The study provides a temporal analysis of MIP publishing across different time periods.

Findings

MIP has an average publication of 43 articles each year, and the number of citations has grown substantially since it started publication. Although contributors to the journal come from around the globe, they most often are affiliated with the United Kingdom, United States, and Australia. Bibliographic coupling of documents reveals that the journal's primary focus has been on issues such as marketing planning, marketing theory, consumer behavior, global marketing, customer relationship management, customer service and branding. Co-authorship analysis reveals that the journal's collaborative network has grown.

Research limitations/implications

This study uses data from the Scopus database, and any limitations of the database have implications for the findings.

Originality/value

First analysis of this kind of papers published in MIP

Abstract

As a result of a badly conceived farm policy the bulk of the EC′s dried grape crop of 1981/82 was sold into intervention. Minimum import prices (MIPs) were introduced, throwing the import trade into confusion, and distorting the market for dried grapes. MIPs meant that the competitive advantage of low cost suppliers was lost, and the importer′s traditional skills of buying cheap were thwarted. Failure to distinguish between types of product, quality and presentation, led to further difficulties. Even marginal failure to respect the MIP led to the application of substantial countervailing charges. In February 1988 a ruling of the European Court gave some relief to the beleaguered trade.

Abstract

Purpose

The traveling purchaser problem (TPP) has gained attention in academics to deal with different variants in real business world. This study aims to study a green TPP with quantity discounts and soft time windows (TPPQS), in which a firm needs to purchase products from a set of available markets and deliver the products to a set of customers.

Design/methodology/approach

Vehicles are available to visit the markets, which offer products at different prices and with different quantity discount schemes. Soft time windows are present for the markets and the customers, and earliness cost and tardiness may incur if a vehicle cannot arrive a market or a customer within the designated time interval. The environmental impact of transportation activities is considered. The objective of this research is to minimize the total cost, including vehicle-assigning cost, vehicle-traveling cost, purchasing cost, emission cost, earliness cost and tardiness cost, while meeting the total demand of the customers and satisfying all the constraints. A mixed integer programming (MIP) model and a genetic algorithm (GA) approach are proposed to solve the TPPQS.

Findings

The results show that both the MIP and the GA can obtain optimal solutions for small-scale cases, and the GA can generate near-optimal solutions for large-scale cases within a short computational time.

Practical implications

The proposed models can help firms increase the performance of customer satisfaction and provide valuable supply chain management references in the service industry.

Originality/value

The proposed models for TPPQS are novel and can facilitate firms to design their green traveling purchasing plans more effectively in today’s environmental conscious and competitive market.

Abstract

Purpose

Molecularly imprinted polymers (MIPs) have aroused focus in medicinal chemistry in recent decades, especially for biomedical applications. Considering the exceptional abilities to immobilize any guest of medical interest (antibodies, enzymes, etc.), MIPs is attractive to substantial research efforts in complementing the quest of biomimetic recognition systems. This study aims to review the key-concepts of molecular imprinting, particularly emphasizes on the conformational adaptability of MIPs beyond the usual description of molecular recognition. The optimal morphological integrity was also outlined in this review to acknowledge the successful sensing activities by MIPs.

Design/methodology/approach

This review highlighted the fundamental mechanisms and underlying challenges of MIPs from the preparation stage to sensor applications. The progress of electrochemical and optical sensing using molecularly imprinted assays has also been furnished, with the evolvement of molecular imprinting as a research hotspot.

Findings

The lack of standard synthesis protocol has brought about an intriguing open question in the selection of building blocks that are biocompatible to the imprint species of medical interest. Thus, in this paper, the shortcomings associated with the applications of MIPs in electrochemical and optical sensing were addressed using the existing literature besides pointing out possible solutions. Future perspectives in the vast development of MIPs also been postulated in this paper.

Originality/value

The present review intends to furnish the underlying mechanisms of MIPs in biomedical diagnostics, with the aim in electrochemical and optical sensing while hypothesizing on future possibilities.

Abstract

Purpose

This paper aims to introduce a new mixed integer programming formulation and associated heuristic algorithm to solve the Military Nodal Capacity Problem, which is a type of supply chain network design problem that involves determining the amount of capacity expansion required at theater nodes to ensure the on-time delivery of military cargo.

Design/methodology/approach

Supply chain network design, mixed integer programs, heuristics and regression are used in this paper.

Findings

This work helps analysts at the United States Transportation Command identify what levels of throughput capacities, such as daily processing rates of trucks and railcars, are needed at theater distribution nodes to meet warfighter cargo delivery requirements.

Research limitations/implications

This research assumes all problem data are deterministic, and so it does not capture the variations in cargo requirements, transit times or asset payloads.

Practical implications

This work gives military analysts and decision makers prescriptive details about nodal capacities needed to meet demands. Prior to this work, insights for this type of problem were generated using multiple time-consuming simulations often involving trial-and-error to explore the trade space.

Originality/value

This work merges research of supply chain network design with military theater distribution problems to prescribe the optimal, or near-optimal, throughput capacities at theater nodes. The capacity levels must meet delivery requirements while adhering to constraints on the proportion of cargo transported by mode and the expected payloads for assets.

Abstract

Purpose

The purpose of this paper is to present a mask‐image‐projection‐based stereolithography (MIP‐SL) process that can combine two base materials with various concentrations and structures to produce a solid object with desired material characteristics. Stereolithography is an additive manufacturing process in which liquid photopolymer resin is cross‐linked and converted to solid. The fabrication of digital material requires frequent resin changes during the building process. The process presented in this paper attempts to address the related challenges in achieving such fabrication capability.

Design/methodology/approach

A two‐channel system design is presented for the multi‐material MIP‐SL process. In such a design, a coated thick film and linear motions in two axes are used to reduce the separation force of a cured layer. The material cleaning approach to thoroughly remove resin residue on built surfaces is presented for the developed process. Based on a developed testbed, experimental studies were conducted to verify the effectiveness of the presented process on digital material fabrication.

Findings

The proposed two‐channel system can reduce the separation force of a cured layer by an order of magnitude in the bottom‐up projection system. The developed two‐stage cleaning approach can effectively remove resin residue on built surfaces. Several multi‐material designs have been fabricated to highlight the capability of the developed MIP‐SL process.

Research limitations/implications

A proof‐of‐concept testbed has been developed. Its building speed and accuracy can be further improved. The tests were limited to the same type of liquid resins. In addition, the removal of trapped air is a challenge in the presented process.

Originality/value

This paper presents a novel and a pioneering approach towards digital material fabrication based on the stereolithography process. This research contributes to the additive manufacturing development by significantly expanding the selection of base materials in fabricating solid objects with desired material characteristics.
