Clusters in formation in a deindustrialized area: urban regeneration and structural change in Porto Marghera (Venice)
Authors: Bonello Valentina , Faraone Claudia , Gambarotto Francesca , Nicoletto Luca , Pedrini Giulio 
Published: May 2020

PurposeThis paper aims to provide a comprehensive vision of the formation of intra-metropolitan clusters triggered by the deindustrialization of an urban area, namely, the district of Porto Marghera in the metropolitan area of Venice and propose possible regeneration scenarios based on intra-metropolitan clustering.Design/methodology/approachThis paper adopts a multi-disciplinary approach and relies on both descriptive and qualitative evidence to show the economic transition occurred in the area of Porto Marghera in recent years.FindingsEvidence shows the rise of two potential clusters in the KIBS and the creative industries in a well-delimited fringe area placed at the boundary between the urban centre and the core of the deindustrialized zone. Such clustering processes have been, however, characterized by two different and in some way alternative paths. The former stems from the combination of two autonomous entrepreneurial ideas that complemented one to each other. The latter relies on university-industry collaboration and on the presence of places of informal exchanges that proved to support personal networking, knowledge exchange and business opportunities.Research limitations/implicationsThis paper suggests that local development policies could leverage on the presence of social entrepreneurs to substitute the creation of amenities and the provision of public goods in fragile territories.Originality/valueThis paper shows that, in presence of specific spatial conditions, deindustrialization can stimulate the formation of new intra-metropolitan through both top-down and bottom-up agglomeration process.

Authors: Hua Mengjie , Yang Shuo , Xu Quan , Chen Mo , Wu Huagan , Bao Bocheng 
Published: May 2020

Purpose
The purpose of this paper is to develop two types of simple jerk circuits and to carry out their dynamical analyses using a unified mathematical model.

Design/methodology/approach
Two types of simple jerk circuits only involve a nonlinear resistive feedback channel composited by a nonlinear device and an inverter. The nonlinear device is implemented through parallelly connecting two diode-switch-based series branches. According to the classifications of switch states and circuit types, a unified mathematical model is established for these two types of simple jerk circuits, and the origin symmetry and scale proportionality along with the origin equilibrium stability are thereby discussed. The coexisting bifurcation behaviors in the two types of simple jerk systems are revealed by bifurcation plots, and the origin symmetry and scale proportionality are effectively demonstrated by phase plots and attraction basins. Moreover, hardware experimental measurements are performed, from which the captured results well validate the numerical simulations.

Findings
Two types of simple jerk circuits are unified through parallelly connecting two diode-switch-based series branches and a unified mathematical model with six kinds of nonlinearities is established. Especially, the origin symmetry and scale proportionality for the two types of simple jerk systems are discussed quantitatively. These jerk circuits are all simple and inexpensive, easy to be physically implemented, which are helpful to explore chaos-based engineering applications.

Originality/value
Unlike previous works, the significant values are that through unifying these two types of simple jerk systems, a unified mathematical model with six kinds of nonlinearities is established, upon which symmetrically scaled coexisting behaviors are numerically disclosed and experimentally demonstrated.
Memristor emulator – a nonlinear load for reduction of ferroresonance in a single-phase transformer
Authors: Sridharan Poornima , C. Pugazhendhi Sugumaran 
Published: May 2020

PurposeAn annual substation equipment failure report says 3/7 capacitive voltage transformer (CVT) got damaged because of ferroresonance overvoltage. The conventional mitigation circuit fails to protect the transformer as the overvoltage may fall in the range between 2 and 4 per unit. It is necessary to develop a device to suppress the overvoltage as well as overcurrent of the CVT. This study aims to propose the suitability of memristor emulator as a mitigation circuit for ferroresonance.Design/methodology/approachThe literature implies that a nonlinear circuit can protect the transformer against ferroresonance. An attempt is made with a memristor emulator using Operational Amplifier (OPAMP) for the mitigation of ferroresonance in a prototype transformer. The circuit is simulated using PSpice and validated for its ideal characteristics using hardware implementation. The nonlinear memductance is designed which is required to mitigate the ferroresonance. The mitigation performance has been compared with conventional method along with fast Fourier transform (FFT) analysis.FindingsWhile the linear resistor recovers the secondary voltage by 74.1%, the memristor emulator does it by 82.05% during ferroresonance. Also, the total harmonic distortion (THD) of ferroresonance signal found to be 22.06% got improved as 2.56% using memristor emulator.Research limitations/implicationsThe suitability of memristor emulator as a mitigation circuit for ferroresonance is proposed in this paper. As ferroresonance occurs in instrument transformers which have extra high voltage (EHV) rated primary windings and (110 V/[110 V/1.732]) rated secondary windings, the mitigation device is proposed to be connected as a nonlinear load across the secondary windings of the transformer. This paper discusses the preliminary work of ferroresonance mitigation in a prototype transformer. The mitigation circuit may have memristor or meminductor for ferroresonance mitigation when they are commercially available in future.Practical implicationsThe electronic component-based memristor emulator may not work at 110 V practically as they may be rated at low power. Hence, chemical component-based memristor emulator was developed to do the same. The authors like to clarify that the memristor will be a solution for ferroresonance in future not the memristor emulator circuit.Social implicationsWith the real form of memristor, the transistor world will be replaced by it and may have a revolution in the field of electronics, VLSI, etc. This contribution attempts to project the use of memristor in a smaller scale in high-voltage engineering.Originality/valueThe electronic component-based memristor emulator is proposed as a mitigation circuit for ferroresonance. The hypothesis has been verified successfully in a prototype transformer. Testing circuit of memristor emulator involves transformer, practically. The mitigation performance has been compared with conventional method technically and justified with FFT analysis.

Digital information literacy skills of Pakistani librarians: exploring supply-demand mismatches, adoption strategies and acquisition barriers
Authors: Khan Asad 
Published: May 2020

Purpose
This study aimed to examine the current and needed levels of the digital information literacy (DIL) skills of Pakistani librarians and further explored the strategies of and barriers to its acquisition and/or enhancement.

Design/methodology/approach
Using the quantitative approach, a cross-sectional survey was conducted. A convenience sample of Pakistani university librarians was recruited. Out of 225 distributed questionnaires, only 180 surveys were returned, a response rate of 80%. Descriptive and inferential statistics were used for data analyzes.

Findings
The present status of DIL skills was found low and there is a high demand for its acquisition. The results also explored that the present level of DIL skills is not matching with its required level and thus training is needed. Further, strategies adopted for its attainment were identified including training programs, seminars and social media. Additionally, barriers in the attainment of DIL skills were also established including librarians’ lack of interest, poor internet facilities, absence of users’ demand, no training programs and lack of collaboration between the faculty and librarians.

Research limitations/implications
This study was limited to librarians serving in three different universities of Pakistan. The findings of this study may motivate librarians toward the adoption of digital innovations. This study also informs librarians to recognize gaps in their DIL skills and should attempt to diminish it using diverse strategies. The results also inform the concerned authorities about the barriers faced by librarians in the acquisition of DIL skills and can plan for training programs. Additionally, LIS curriculum should be revised to incorporate topics related to the learning of innovative digital skills. Finally, results motivate librarians to attain DIL skills that possibly augment their performance.

Originality/value
This study is the first attempt in Pakistan that examined supply-demand mismatches, adoption strategies and acquisition barriers in the context of librarians’ DIL skills serving in the university libraries of Peshawar. As the current status of DIL skills of Pakistani librarians was found low, thus university authorities should organize professional development programs for librarians to acquire and/or enhance the DIL skills.
Identifying financial statement fraud with decision rules obtained from Modified Random Forest
Authors: An Byungdae , Suh Yongmoo 
Published: May 2020

PurposeFinancial statement fraud (FSF) committed by companies implies the current status of the companies may not be healthy. As such, it is important to detect FSF, since such companies tend to conceal bad information, which causes a great loss to various stakeholders. Thus, the objective of the paper is to propose a novel approach to building a classification model to identify FSF, which shows high classification performance and from which human-readable rules are extracted to explain why a company is likely to commit FSF.Design/methodology/approachHaving prepared multiple sub-datasets to cope with class imbalance problem, we build a set of decision trees for each sub-dataset; select a subset of the set as a model for the sub-dataset by removing the tree, each of whose performance is less than the average accuracy of all trees in the set; and then select one such model which shows the best accuracy among the models. We call the resulting model MRF (Modified Random Forest). Given a new instance, we extract rules from the MRF model to explain whether the company corresponding to the new instance is likely to commit FSF or not.FindingsExperimental results show that MRF classifier outperformed the benchmark models. The results also revealed that all the variables related to profit belong to the set of the most important indicators to FSF and that two new variables related to gross profit which were unapprised in previous studies on FSF were identified.Originality/valueThis study proposed a method of building a classification model which shows the outstanding performance and provides decision rules that can be used to explain the classification results. In addition, a new way to resolve the class imbalance problem was suggested in this paper.

Authors: Wang Yuhe , Ye Gui , Zhang Yuxin , Mu Ping , Wang Hongxia 
Published: May 2020

PurposeIn response to the 2008 financial crisis, the performance of the Chinese construction industry seems to be more successful, especially in total factor productivity growth (TFPG) and its contribution (TFPGC). Hence, the purpose of this paper is to investigate and reveal the potential successful lessons in this regard.Design/methodology/approachThis study is conducted innovatively based on a special comparative analysis of TFPG and TFPGC between pre- and post-2008 financial crisis. Solow Residual Approach is used to measure TFPG and TFPGC for the period 2002–2016. Given that the crisis hit China at the end of 2008, the pre-2008 financial crisis period is from 2002 to 2008, and the post-2008 financial crisis period is limited to 2009–2016.FindingsThe results indicate that the industry indeed has better performance in promoting TFPG and TFPGC, TFP thus achieved significant accumulative growth before and after the crisis. However, from an evolutionary perspective, both TFPG and TFPGC presented an overall downward trend from before the crisis to after the crisis. Further, the game between the centrally planned economy and the market-oriented economy was identified and revealed as the essential reason behind the evolution of TFPG and TFPGC.Practical implicationsSome valuable lessons for policies and practices in promoting TFPG and TFPGC were summarized and learned from the Chinese experience, such as reducing administrative intervention and making the construction market play a decisive role.Originality/valueThis study provides some new empirical evidence to enrich the overall body of knowledge on growth theory, especially in promoting TFPG and TFPGC.
The emotional side of organizational decision-making: examining the influence of messaging in fostering positive outcomes for the brand
Authors: Kemp Elyria , Briggs Elten , Anaza Nwamaka A. 
Published: May 2020

PurposeResearchers and practitioners have traditionally maintained that organizational buying requires rational decision-making. However, individuals at organizations make decisions daily applying a confluence of rationalizations and emotions. This study aims to address the roles of personal feelings, facts and emotional advertising content in the organizational decision-making process.Design/methodology/approachIn two studies, the authors apply both qualitative and quantitative methods to explore emotional and cognitive reactions to advertising. In Study 1, depth interviews were conducted with marketing and advertising content developers from a Fortune 100 technology company. In Study 2, a web-based survey was sent out to a Fortune 100 company’s buyer panel.FindingsResults suggest that advertising using emotion-based themes helps to foster brand engagement tendencies and advocacy for a brand. Findings also demonstrate that organizational status (C-level executive’s vs non-C-level employees) moderates the relationship between buyers’ reliance on facts and their receptivity to advertising using emotion-based themes, such that reliance on facts increases the appeal of emotional advertising.Research limitations/implicationsThis research contributes to the organizational buying literature by addressing the dearth of research on the role of emotions in organizational decision-making and providing insight into the role of advertising in business-to-business (B2B) decision-making.Practical implicationsThese results imply that advertising incorporating emotion-based themes provide meaningful information to B2B buyers and is especially effective when targeted at buyers at higher levels in an organization.Originality/valueB2B buying behavior has traditionally been considered a rational undertaking. This research explores how decision-making orientation and the presence of advertising using emotion-based themes help to foster engagement and advocacy for the brand.
Gamification in sport apps: the determinants of users' motivation
Authors: Bitrián Paula , Buil Isabel , Catalán Sara 
Published: May 2020

PurposeGamification is a tool with great potential to motivate individuals to increase their physical activity. That is why sport apps for mobile devices, such as Nike+ or Strava, have integrated game elements. There is, however, little evidence of gamification's effectiveness in this field. Therefore, the aim of the present study is to analyze the impact of game elements included in gamified sports' apps on the satisfaction of basic psychological needs (i.e. competence, autonomy and relatedness). Similarly, the research analyzes the impact of these needs on autonomous motivation.Design/methodology/approachTo achieve these goals, data were collected from users of gamified sport apps, using an online questionnaire. The data were analyzed using partial least squares structural equation modeling.FindingsThe results showed that interaction in the app with achievement-related game elements satisfied the needs for competence, autonomy and relatedness; social-related elements satisfied the need for relatedness; and immersion-related elements satisfied the needs for competence and autonomy. Similarly, satisfaction of the needs for autonomy and relatedness while using the app is crucial to experience autonomous motivation.Practical implicationsThe findings of this study provide guidelines for practitioners and app developers.Originality/valueBased on self-determination theory, the paper provides new insights into the relationship between game elements included in sport apps and individuals' basic psychological needs and motivation.

Purpose
Scientific advances and the emergence of a wide range of broadband services have resulted in the internet developing as a critical component of most peoples’ daily lives. The rapid development of the global economy and improvements to the information network speed and reliability have driven a radical evolution of the concept of “library.” Modern information technologies have not only drastically altered the functionality and accessibility of libraries, but it is no longer a matter of the library community to use scientific and technological innovation ideas and techniques to promote its business. The sample of this study was distributed to the consumers of the Guangdong Intelligent Library for the questionnaire.

Design/methodology/approach
A total of 520 questionnaires were distributed, returning 375 validresponses for an effective recovery rate of 72%.

Findings
Perceptual ease of use has a positive and direct impact on perceptual usefulness. Perceptual ease of use has a positive and direct impact on attitude. Perceptual usefulness has a positive and direct impact on attitude. Perceptual usefulness has a positive direct impact on behavioral intentions. Attitude has a positive and direct impact on behavioral intentions. Subjective norms have a positive and direct impact on behavioral intentions. Perceptual behavioral control has a positive and direct impact on behavioral intentions. Perceptual behavioral control has a positive and direct impact on behavior. Behavioral intentions have a positive and direct impact on behavior.

Originality/value
Based on the survey results and analysis, recommendations are made to help smart libraries integrate artificial intelligence methods to provide highly attractive service offerings in an extremely competitive environment.
Decision-making when organising facilities for a school: a participatory action research approach
Authors: Uotila Ulrika , Saari Arto , Junnonen Juha-Matti 
Published: May 2020

Purpose
Public authorities are required to organise new facilities to respond to changed user demands in terms of a public-owned school. The number of pupils attending the case study school will increase in the following years, as will the number of children attending a day nursery located on the present campus. In addition, the users of the campus have complained of building-related symptoms. This study aims to understand the municipal decision-making process in organising the school’s facilities, in particular, the factors used for decreasing uncertainty around a project.

Design/methodology/approach
This study is a case study undertaken through an action research approach. The researchers participated in the project planning meetings concerning the future activities to take place in the building.

Findings
Over a 13-month period, multiple stakeholders participated in the project planning meetings providing a deeper understanding of the space demands posed, current challenges and opportunities offered by the existing building. In addition, the alternative solutions generated were evaluated. The problem identification and information gathering periods lasted over nine months, which was far longer than predicted. Thus, generating alternative solutions and evaluation of the solutions also delayed. As the entire process was delayed substantially, the final decision on organising the facilities was not made during this research.

Practical implications
This research may be of practical value for a property owner and a project team for decision-making concerning changed facility demands.

Originality/value
This paper provides information about how public authorities are making decisions on facility organisation during conditions of uncertainty.
