Exhaustive Study

The large number of vehicles constantly seeking access to congested areas in cities means that finding a public parking place is often difficult and causes problems for drivers and citizens alike. In this context, strategies that guide vehicles from one point to another, looking for the most optimal path, are needed. Most contributions in the literature are routing strategies that take into account different criteria to select the optimal route required to find a parking space. This paper aims to identify the types of smart parking systems (SPS) that are available today, as well as investigate the kinds of vehicle detection techniques (VDT) they have and the algorithms or other methods they employ, in order to analyze where the development of these systems is at today. To do this, a survey of 274 publications from January 2012 to December 2019 was conducted. The survey considered four principal features: SPS types reported in the literature, the kinds of VDT used in these SPS, the algorithms or methods they implement, and the stage of development at which they are. Based on a search and extraction of results methodology, this work was able to effectively obtain the current state of the research area. In addition, the exhaustive study of the studies analyzed allowed for a discussion to be established concerning the main difficulties, as well as the gaps and open problems detected for the SPS. The results shown in this study may provide a base for future research on the subject.

Purpose The purpose of this paper is to explore the current state of popular modern methods of construction (MMC) and pre-manufactured construction in the construction industry and propose a framework for future implications for practice and future research. Design/methodology/approach This technical paper is based on a narrative review of the extant literature on the subject. First, the Scopus search engine was used to retrieve relevant papers on MMC, offsite and pre-manufactured construction. Second, institutional literature such as reports by industry professional and trade bodies, literature from leading technology firms and contractors with experience of MMC were extracted. These two strands of literature were synthesised and a comprehensive discussion on the topic was provided. Findings Results show that journal publications on MMC and pre-manufactured construction have increased in the past decade. The paper found significant advances in the development of premanufactured and offsite construction approaches with many benefits. Offsite and pre-manufactured construction are viable and sustainable systems currently suitable for wider adoption as the mainstream construction method. Research limitations/implications This technical paper based on an integrative review of relevant literature could have benefitted from interviews of professionals with experience of offsite and pre-manufacture techniques and from wider availability of current academic publications on the subject. Validation of the framework has not been undertaken. Originality/value Not much-published work has been undertaken on the current state of development globally and the viability of these construction approaches. This paper evaluates evidence from academic and industry sources to address this gap. A framework has been developed which can help the industry’s industrialisation drive.

A survey of the field of control for flexible multi-link robots is presented. This research area has drawn great attention during the last two decades, and seems to be somewhat less “attractive” now, due to the many satisfactory results already obtained, but also because of the complex nature of the remaining open problems. Thus it seems that the time has come to try to deliver a sort of “state of the art” on this subject, although an exhaustive one is out of scope here, because of the great amount of publications. Instead, we survey the most salient progresses – in our opinion – approximately during the last decade, that are representative of the essential different ideas in the field. We proceed along with the exposition of material coming from about 119 included references. We do not pretend to deeply present each of the methods quoted hereafter; however, our goal is to briefly introduce most of the existing methods and to refer the interested reader to more detailed presentations for each scheme. To begin with, a now well-established classification of the flexible arms control goals is given. It is followed by a presentation of different control strategies, indicating in each case whether the approach deals with the one-link case, which can be successfully treated via linear models, or with the multi-link case which necessitates nonlinear, more complex, models. Some possible issues for future research are given in conclusion.

There has been much recent activity in the research area of nanoparticles and nanocrystalline materials, in many fields of science and technology. This is due to their outstanding and unique physical, mechanical, chemical and biological characteristics. Recent developments in biomineralization have demonstrated that nano-sized particles play an important role in the formation of the hard tissues of animals. It is well established that the basic inorganic building blocks of bones and teeth of mammals are nano-sized and nanocrystalline calcium orthophosphates (in the form of apatites) of a biological origin. In mammals, tens to hundreds of nanocrystals of biological apatite are found to combine into self-assembled structures under the control of bio-organic matrixes. It was also confirmed experimentally that the structure of both dental enamel and bones could be mimicked by an oriented aggregation of nano-sized calcium orthophosphates, determined by the biomolecules. The application and prospective use of nano-sized and nanocrystalline calcium orthophosphates for clinical repair of damaged bones and teeth are also known. For example, a greater viability and a better proliferation of various cells were detected on smaller crystals of calcium orthophosphates. Furthermore, studies revealed that the differentiation of various cells was promoted by nano-sized calcium orthophosphates. Thus, the nano-sized and nanocrystalline forms of calcium orthophosphates have the potential to revolutionize the field of hard tissue engineering, in areas ranging from bone repair and augmentation to controlled drug delivery devices. This paper reviews the current state of knowledge and recent developments of various nano-sized and nanocrystalline calcium orthophosphates, covering topics from the synthesis and characterization to biomedical and clinical applications. This review also provides possible directions of future research and development.

The Subject

Recently, some authors have pointed out that the subject of university–firm collaboration (UFC) in the teaching context has been neglected. To fill this gap, and considering that educational provision is co-created with various stakeholders, this study aims to provide an exploratory characterization of the current state of UFC in the teaching context and to explore UFC as a mechanism for the co-creation of value. A qualitative approach was chosen, through a case study applied to one faculty at a Portuguese university. Data were obtained through documentary analysis and interviews with people in charge of this faculty. The results suggest that collaboration activities in this domain occur, albeit not systematically or in a planned way. The involvement of the current faculty direction in stimulating this collaboration is recognized, and the leaders see this phenomenon as a mechanism for co-creating value between firms and academia. As a practical contribution, the study proposes a set of recommendations to encourage such UFC. The scientific contribution arises from the presentation of a conceptual structure which explores the UFC phenomenon in the teaching context, bringing together the perspectives of collaboration and the co-creation of educational provision, as well as presenting a number of suggestions for future research.

PurposeThis study investigates system dynamics (SD) applications in performance measurement (PM) research and practice. A bibliometric analysis was conducted to investigate the maturity of this research area and identify opportunities for development.Design/methodology/approachA systematic literature review (SLR) was conducted to provide a comprehensive and rigorous review of the existing literature. The search was conducted on 10 platforms identifying 97 publications, which were evaluated using bibliometric analysis.FindingsThe analysis revealed that applications of SD are most commonly used in the PM system design phase to model organisational performance. In addition, the bibliometric results showed a highly dispersed author set, with most studies using exploratory methods, suggesting that the research is in a relatively early stage of development. The results also showed that over 50 per cent of the causal models were not validated, emphasizing an important methodological gap in this research area.Research limitations/implicationsThis SLR is limited to indexed publications on 10 platforms, the search strategy was relatively precise and only available papers in English language were used for the literature review.Practical implicationsPM systems supported by SD can help managers understand and improve organisational behaviours by addressing dynamic complexities and relationship between variables. This study evaluates the maturity of this research area including information about the current development of this area and opportunities to build on existing knowledge.Originality/valueThis study identifies how SD approaches are applied to PM and highlights areas that require further research consideration. This paper is the first of two publications to result from this study and focuses on evaluating the current state of this research area.

PurposeThe continuous presence and intensity of the Internet of things (IoT) in our lives and the risk of security breaches in traditional transactional and financial platforms are the major cause of personal and organizational data losses. Blockchain emerges as a promised technology to ensure higher levels of data encryption and security. Thus, this study aims to develop a systematic literature review analyzing the previous literature and to purpose of a framework to better understand the process of blockchain security.Design/methodology/approachThe 75 articles reviewed were obtained through the Scopus database and a bibliographic-coupling analysis was developed to identify the main themes of this research area, via VOSviewer software.FindingsThe results enable the categorization of the existing literature revealing four clusters: 1) feasibility, 2) fintech and cryptocurrency, 3) data trust and share and 4) applicability. Blockchain technology is still in its early stage of development and counting on researchers in security and cryptography to take it further to new highs, to allow its applicability to different areas and in long-term scenarios.Originality/valueThis systematic literature creates a base to reduce the blockchain security literature gap. In addition, it provides a framework that enables the scientific community to access the main subjects discussed and the articulation between concepts. Furthermore, it enhances the state-of-the-art literature on blockchain security and proposes a future research agenda.

There has been a rapid growth in the research concerning mobile phones and the delivery of the learning experience in developing countries in recent years. The aim of this chapter is to improve understanding of this expanding research area and in so doing consider the potential for mobile phone applications for the delivery of educational services for the poor. The current state of knowledge is assessed by reviewing the existing research articles drawn from both peer-reviewed academic journals and non-peer reviewed studies and other practitioner-orientated sources. Issues relating to educational needs and the measurement of impacts have been comparatively neglected, whilst application design and adoption have received greater attention. Emphasis tends to be on devices and new ways to deliver services, but ignores the broader context of educational services for the poor and tends to be technology-led (Duncombe, 2006). In order to correct this imbalance in research, the paper identifies key points relating to concepts, methodologies, issues addressed and evidence presented and provides pointers to future research directions.

Purpose The purpose of this paper is to advance contemporary cognisance of the leadership field and its current state, through the synthesis and development of earlier contributions. A taxonomy of evolutionary eras is tendered, from which future research opportunities can be extrapolated. Design/methodology/approach This paper conducts a narrative literature review of significant leadership literature. There is a focus on prominent contributions which are considered to have been highly influential within the field, while acknowledging other notable influences. Findings Leadership is found to be a multifaceted and evolving field, which continues to produce further research fields. This dynamism hinders the progression of leadership to achieve integration. Eleven interrelated eras of leadership, which hold varying research value, were found. While some eras superficially appear to be discredited, there is arguably scope for these to be developed in contemporary context. Currently, the leadership approaches which are replete with research opportunities include servant leadership, a skills approach and an entrepreneurial leadership. Research limitations/implications Leadership is a vast research area with numerous contributions to its body of work; therefore, this review has focused on prominent contributions and has not attempted to include all available literature. The dissemination of leadership literature has allowed for research gaps to emerge and future research recommendations to be drawn. Originality/value While there is an extensive body of leadership literature, there are few reviews of the literature. A comprehensive contemporary review facilitates an examination of the current complexities and state of the leadership field.

The tourism program “Pueblos Mágicos” was created in 2001 by the Mexican Secretary of Tourism (Sectur), together with its brand, with the aim of promoting tourism by preserving secular and ancestral traditions, as well as revitalizing cities and towns that make great efforts to protect and safeguard their cultural wealth. In this context, the aim of this research work is to show the current state of scientific research carried out within the context of the Magic Towns of Mexico. The work methodology is based on the bibliometric analysis of the scientific production indexed in two main international databases: Web of Science and Scopus. The application of this technique will make it possible to obtain a scientific mapping of the production (growth, researchers in the subject, production impact through the number of citations, network analysis, etc.), with the aim of observing the evolution in the generation of knowledge regarding this tourism development tool that acts as a distinctive brand for tourism in Mexico. This mapping is useful for researchers as it provides information on the research carried out so far, allowing them to identify gaps to work on in their future research work. The systematic search process identified 52 articles. The results indicate that the research carried out in this context is incipient, with few researchers addressing the subject on a continuous basis and most of them being transient researchers with a single article. Most of the research was approached from the perspective of cultural heritage, cultural resources, inherited resources, cultural tourism, public policy, local development and sustainable tourism, and sustainable development. In light of the number of articles published, all of these can be considered to be incipient lines of research.
