Published: October 2019

The synthesis and crystal structures of 2-(4-fluorophenyl)-3-phenyl-2,3-dihydro-4H-pyrido[3,2-e][1,3]thiazin-4-one toluene hemisolvate (1), C19H13FN2OS·0.5C7H8, and 2-(4-nitrophenyl)-3-phenyl-2,3-dihydro-4H-pyrido[3,2-e][1,3]thiazin-4-one isopropanol 0.25-solvate 0.0625-hydrate (2), C19H13N3O3S·0.25C3H7O·0.0625H2O, are reported. Both are racemic mixtures (centrosymmetric crystal structures) of the individual compounds and incorporate solvent molecules in their structures. Compound 2 has four thiazine molecules in the asymmetric unit. All the thiazine rings in this study show an envelope pucker, with the C atom bearing the substituted phenyl ring displaced from the other atoms. The phenyl and aryl rings in each of the molecules are roughly orthogonal to each other, with dihedral angles of about 75°. The extended structures of 1 and 2 are consolidated by C—H...O and C—H...N(π), as well as T-type (C—H...π) interactions. Parallel aromatic ring interactions (π–π stacking) are observed only in 2.

Authors: Johnston Dean H. , Agho Ikponmwosa
Published: October 2019

Charge-assisted hydrogen bonding plays a significant role in the crystal structures of solvates of ionic compounds, especially when the cation or cations are primary ammonium salts. We report the crystal structures of four ammonium salts of molybdenum halide cluster solvates where we observe significant hydrogen bonding between the solvent molecules and cations. The crystal structures of bis(anilinium) octa-μ3-chlorido-hexachlorido-octahedro-hexamolybdate N,N-dimethylformamide tetrasolvate, (C6H8N)2[Mo6Cl8Cl6]·4C3H7NO, (I), p-phenylenediammonium octa-μ3-chlorido-hexachlorido-octahedro-hexamolybdate N,N-dimethylformamide hexasolvate, (C6H10N2)[Mo6Cl8Cl6]·6C3H7NO, (II), N,N′-(1,4-phenylene)bis(propan-2-iminium) octa-μ3-chlorido-hexachlorido-octahedro-hexamolybdate acetone trisolvate, (C12H18N2)[Mo6Cl8Cl6]·3C3H6O, (III), and 1,1′-dimethyl-4,4′-bipyridinium octa-μ3-chlorido-hexachlorido-octahedro-hexamolybdate N,N-dimethylformamide tetrasolvate, (C12H14N2)[Mo6Cl8Cl6]·4C3H7NO, (IV), are reported and described. In (I), the anilinium cations and N,N-dimethylformamide (DMF) solvent molecules form a cyclic R

2(8) hydrogen-bonded motif centered on a crystallographic inversion center with an additional DMF molecule forming a D(2) interaction. The p-phenylenediammonium cation in (II) forms three D(2) interactions between the three N—H bonds and three independent N,N-dimethylformamide molecules. The dication in (III) is a protonated Schiff base solvated by acetone molecules. Compound (IV) contains a methyl viologen dication with N,N-dimethylformamide molecules forming close contacts with both aromatic and methyl H atoms.
Crystal structures of the two isomeric hydrogen-bonded cocrystals 2-chloro-4-nitrobenzoic acid–5-nitroquinoline (1/1) and 5-chloro-2-nitrobenzoic acid–5-nitroquinoline (1/1)
Authors: Gotoh Kazuma , Ishida Hiroyuki
Published: October 2019

The structures of two isomeric compounds of 5-nitroquinoline with chloro- and nitro-substituted benzoic acid, namely, 2-chloro-4-nitrobenzoic acid–5-nitroquinoline (1/1), (I), and 5-chloro-2-nitrobenzoic acid–5-nitroquinoline (1/1), (II), both C7H4ClNO4·C9H6N2O2, have been determined at 190 K. In each compound, the acid and base molecules are held together by an O—H...N hydrogen bond. In the crystal of (I), the hydrogen-bonded acid–base units are linked by a C—H...O hydrogen bond, forming a tape structure along [1\overline{2}0]. The tapes are stacked into a layer parallel to the ab plane via N—O...π interactions between the nitro group of the base molecule and the quinoline ring system. The layers are further linked by other C—H...O hydrogen bonds, forming a three-dimensional network. In the crystal of (II), the hydrogen-bonded acid–base units are linked into a wide ribbon structure running along [1\overline{1}0] via C—H...O hydrogen bonds. The ribbons are further linked via another C—H...O hydrogen bond, forming a layer parallel to (110). Weak π–π interactions [centroid–centroid distances of 3.7080 (10) and 3.7543 (9) Å] are observed between the quinoline ring systems of adjacent layers. Hirshfeld surfaces for the 5-nitroquinoline molecules of the two compounds mapped over shape index and d
norm were generated to visualize the weak intermolecular interactions.
Study on unbiased interval grey number prediction model with new information priority
Authors: Li Ye , Li Juan
Published: October 2019

Purpose

The purpose of this paper is to construct an unbiased interval grey number prediction model with new information priority for dealing with the jumping errors from difference equation to the differential equation in the prediction model of interval grey number.

Design/methodology/approach

First, this study obtains a set of linear equations about the model parameters by taking the minimum error sum of squares between the accumulative sequence and its simulation values as criterion, and solves them on the basis of the Crammer rule. Then, according to the new information priority principle, it selects the last number of the accumulated generation sequence as the initial value and gives the expression of the time response function by the recursive iteration method to establish the interval grey number prediction model.

Findings

This paper provides an unbiased interval grey number prediction model with new information priority, and the example analysis shows that the method proposed in this paper has higher prediction precision and practicality.

Research limitations/implications

If there is a better method to whiten the interval grey number, so as to fully tap the grey information contained in it, the accuracy of the model will be higher.

Practical implications

The model proposed in this paper can avoid the error caused by jumping from difference equation to differential equation and make full use of new information. It can be better used in a problem where new information has a great influence on prediction results.

Originality/value

This paper selects the last number of the accumulated generation sequence as the initial value and gives the expression of the time response function by the recursive iteration method. Then, it constructs an unbiased interval grey number prediction model with new information priority.
Technology integration for students’ information and digital literacy education in academic libraries
Authors: Rafi Muhammad , JianMing Zheng , Ahmad Khurshid
Published: October 2019

Purpose

Digital literacy has become a widely studied topic for connecting people, participation in government and public affairs. It encourages library professionals to train students and effectively acquire, preserve and disseminate knowledge. Academic libraries involve using digital technology improved the students’ level of digital literacy and technological skills. This paper aims to understand the students’ technological competence in using database resources and searching for online information. In addition, to evaluate the training contents and designated instructors on digital literacy education, the study also focuses on digitally exposed students’ learning behavior, the library management and students’ academic interaction on new technological trends.

Design/methodology/approach

This study uses a quantitative method for which primary data were collected from university students using a structured research questionnaire. Through targeted random sampling techniques, 1,500 printed questionnaires were distributed among students, and 1,266 (84.4%) responses were received. The authors applied descriptive statistics to analyze the demographic information of male and female students. The statistical technique Chi-square test (χ2) was applied using SPSS to determine the association between variables. Moreover, Bonferroni correction for the new a value [modified = 0.05/number of possible comparisons/analysis for each question shown in Tables (II-IX)] was also used to avoid a family-wise error.

Findings

The results inferred a strong association between students’ technological skill with using digital tools, utilization of database resources and browsing networked information on the Web. The association between universities in terms of recruiting designated instructors on digital literacy education, introducing ICT based curriculum and the association between library management in maintaining a regular training program on digital literacy demonstrated a negative association. Besides, the findings disclosed that student’s digital exposure is not the forcing factor in developing technological competence, but found to be a more encouraging factor. It was also concluded that library technological involvement significantly improves student technology-based learning skills.

Practical implications

The results obtained after the analyzed data may help library management in providing long-term strategy for improving digital literacy education and training for students in the effective utilization of technology for better academic performance and social integration.

Originality/value

The study was based on quantitative methods using a questionnaire. Extensive database coverage and digital literacy skills based on coach input can improve student performance and academic quality.
Understanding second grader’s computational thinking skills in robotics through their individual traits
Authors: Baek Youngkyun , Yang Dazhi , Fan Yibo
Published: October 2019

Purpose

This study aims to investigate the relationship between the personal traits and computational thinking skills of second graders within the context of robotics activities.

Design/methodology/approach

Through literature review, a research model and hypotheses were tested with 122 second graders after robotic activities.

Findings

The hypothesized model showed that learning preference, intrinsic motivation and self-efficacy were the main predictors of coding achievement and computational thinking skills, while no direct relationship was found between learning preference, intrinsic or extrinsic motivation. The final path analysis revealed that intrinsic and extrinsic motivation predict self-efficacy, self-efficacy predicts coding achievement and coding achievement predicts computational thinking skills. Another important finding was the strong impact of self-efficacy on coding achievement, as well as computational thinking skills. Results are interpreted with reference to implications for potential methods of improving computational thinking skills when using robotics in the lower grades in elementary schools.

Research limitations/implications

This study not only examined these relationships but also proposed, tested and built a research model containing a wide range of personal traits based on path analysis and multiple regression analysis, which, to the best of the researchers’ knowledge, has not been investigated in the current literature.

Practical implications

As reflected in the final research model, self-efficacy played an important role in impacting second grader’s coding achievement and computational thinking skills.

Originality/value

Few studies have investigated the various relationships in the context of robotics instruction in elementary schools as in this study. Given the increasing popularity of robotics education in elementary schools, the re-examination and identification of the pivotal role of self-efficacy in predicting second graders’ learning of coding and computational thinking skills have important implications for the implementation of robotics education.
Conservation management plans
Authors: Worthing Derek , Organ Samantha
Published: October 2019

Purpose

The purpose of this paper is to identify factors that contribute to the development of an effective conservation management plan (CMP).

Design/methodology/approach

The approach was based on a literature review from which key issues and concerns were identified. This was followed by in-depth interviews with a number of creators and users of CMPs.

Findings

CMPs have developed as an identifiable process with the key stages having a logic and synergy with each other. The research found that undue emphasis was placed on some stages at the expense of others which lead to ineffective management tools often being produced. The reasons for this are related to the interests and background of the creators and a lack of interaction with organisational culture and processes – and importantly a failure to engage with frontline staff. In addition, there were also resource and skill constraints within the client organisation.

Research limitations/implications

Interviews were conducted with six creators (consultants) and seven users. These were mostly from national heritage organisations and specialist heritage consultants. A wider range of user organisations and consultants could be identified for follow-up research. Also those who actually deliver CMPs “on the ground” and day to day could form an important part of the development of this research.

Practical implications

CMPs should be practical working management tools which have to be used by the heritage organisation in order to be effective. This research will hopefully help practitioners focus on what needs to be done in order to produce an effective plan.

Social implications

The conservation of built heritage is essentially concerned with the protection of a social good. CMPs have the potential to provide effective protection of that which is seen as valuable and significant to individuals, groups and society at large.

Originality/value

The management of heritage is an area that is generally under-researched. This work will hopefully be engaged with by academics and practitioners in order to help establish and promote a wider interest in the field.
The power of place in public leadership research and development
Authors: Jackson Brad
Published: October 2019

Purpose

The purpose of this paper is to foreground place as a critical and central concern for public leadership research, development and practice.

Design/methodology/approach

This invited essay draws on the author’s own research and development work engaging in collaborative place-based interventions with academics, policy makers and practitioners.

Findings

Place is one of six heuristic lenses in a Leadership Hexad that has been developed to interrogate and better understand leadership in a multi-dimensional manner. Place can provide an important theoretical and practical fulcrum for bridging both collaborative governance and collective leadership and public and political leadership as well as facilitating cross-sectoral leadership.

Practical implications

This essay argues that more time and effort should be invested into researching and developing place leadership to complement the already extensive efforts to promote collaborative governance and place-based policy initiatives. Place leadership development should be genuinely cross-sectoral in its ambition and should focus on developing emerging and established leaders from the public, private, not-for-profit and indigenous sectors to tackle place-based problems and opportunities.

Originality/value

This essay draws on experience undertaking academic research and conducting leadership development that draws from and feeds into policy and practice. It utilises research from geography, leadership studies, public management, public policy and political science to gain a more sophisticated understanding of the relationship between place and public leadership and how this can be harnessed to improve economic and social impact.
Can family characteristics influence the future labor situation of children? Evidence for Spain
Authors: Morales Marina
Published: October 2019

Purpose

The purpose of this paper is to analyze whether family support, measured through the labor status of parents and the presence of both parents in the household during adolescence, may be an important determinant of unemployment in Spain.

Design/methodology/approach

To address this issue, we follow the Quantity-Quality model of Becker–Lewis (Becker and Lewis, 1973), using data from the Survey of Living Conditions (2011).

Findings

First, the results show that individuals living with both parents at home during their teenage years are less likely to be unemployed in the future. Second, the authors find evidence of the intergenerational transmission of unemployment outcomes, and that the unemployment status of the mother is strongly transferred to the child. Additionally, the authors extend this work to an analysis of other labor characteristics, finding that family support is an important determinant of self-employment and temporary employment. The findings are robust to controls for observable and unobservable characteristics by region, and to the use of different subsamples.

Originality/value

This study can be considered as first evidence of the effect of family support during adolescence on the Spanish labor market.
Do remittances promote human development? Empirical evidence from developing countries
Authors: Huay Chong Siew , Winterton Jonathan , Bani Yasmin , Matemilola Bolaji Tunde
Published: October 2019

Purpose

The purpose of this paper is to analyse the impact of remittances on human development in developing countries using panel data from 1980 to 2014 and to address the critical question of whether the increasing trend of remittances has any impact on human development in a broad range of developing countries.

Design/methodology/approach

Usual panel estimates, such as pooled OLS, fixed or random effects model, possess specification issues such as endogeneity, heterogeneity and measurement errors. In this paper, we, therefore, apply dynamic panel estimates – System generalised method of moment (Sys-GMM) developed by Arellano and Bond (1991) and Arellano and Bover (1995). This estimator is able to control for the endogeneity of all the explanatory variables, account for unobserved country-specific effects that cannot be done using country dummies due to the dynamic structure of the model (Azman-Saini et al., 2010).

Findings

The effect of remittances is statistically significant with positive coefficients in developing countries. The significant coefficient of remittances means that, holding other variables constant, a rise in remittance inflows is associated with improvements in human development. A 10 per cent increase in remittances will lead to an increase of approximately 0.016 per cent in human development. These findings are consistent with Üstubuci and Irdam (2012) and Adenutsi (2010), who found evidence that remittances are positively correlated with human development.

Practical implications

The paper considers implications for policymakers to justify the need for more effective approaches. Policymakers need to consider indicators of human development and to devise public policies that promote income, health and education, to enhance human development.

Originality/value

The question of whether remittances affect human development has rarely been subject to systematic empirical study. Extant research does not resolve the endogeneity problem, whereas the present study provides empirical evidence by utilising dynamic panel estimators such as Sys-GMM to tackle the specification issues of endogeneity, measurement errors and heterogeneity. The present study provides a benchmark for future research on the effect of remittances on human development.
Creativity, innovation and smartness in destination branding
Authors: Trinchini Lino , Kolodii Natalia Andreevna , Goncharova Natalia Aleksandrovna , Baggio Rodolfo
Published: October 2019

Purpose

The purpose of this paper is to examine the role of creativity and innovation as important attributes of smartness in cities/destination branding.

Design/methodology/approach

A conceptual support to the notion of smart destination branding is provided by discussing the relationship between creativity, innovation and technology as determinants for the smartness concept applied to destination branding and marketing. This paper adopts a qualitative and logical-deductive approach. The cases of Milan (Italy) and Tomsk (Russia) are presented and compared as smart cities approach to branding within and outside Europe. The authors emphasise the importance of smart destination branding strategies based on people participation, creativity and innovation as drivers of smart urban development.

Findings

The endogenous ability of cities/destinations to embrace creativity across stakeholders is essential to smart branding strategies relying on advanced information and communication technologies. The entwined connection between smart cities/destinations creative initiatives and innovation underpins innovative branding strategies.

Research limitations/implications

The paper is conceptual and the findings cannot be generalised to other destinations, even if a couple of examples are briefly discussed. The authors intend to provide a basis for future research concerning smart destination branding.

Originality/value

The technological, human and institutional dimensions of smart cities and smart tourism destinations have been increasingly addressed by scholars and practitioners. Despite the reference and attention to human factors is not new, there is still a lack of extensive focus on creativity as crucial driver of innovation in smart destination branding. This paper aims to fill such gap by focussing on the implications of urban smartness driven by creativity and innovation in destination branding and marketing.
An inspection continuum robot with tactile sensor based on electrical impedance tomography for exploration and navigation in unknown environment
Authors: Wang Yaming , Ju Feng , Yun Yahui , Yao Jiafeng , Wang Yaoyao , Guo Hao , Chen Bai
Published: October 2019

Purpose

This paper aims to introduce an aircraft engine inspection robot (AEIR) which can go in the internal of the aircraft engine without collision and detect damage for engine blades.

Design/methodology/approach

To obtain the position and pose information of the blades inside the engine, a novel tactile sensor based on electrical impedance tomography (EIT) is developed, which could provide location and direction information when it contacts with an unknown object. In addition, to navigate the continuum robot, a control method is proposed to control the continuum robot, which can control the continuum robot to move along the pre-planned path and reduce the deviation from the planned path.

Findings

Experiment results show that the average error of contact location measurement of the tactile sensor is 0.8 mm. The average error relative to the size (diameter of 18 mm) of the sensor is 4.4%. The continuum robot can successfully reach the target position through a gap of 30 mm and realize the spatial positioning of blades. The validity of the AEIR for engine internal blade detection is verified.

Originality/value

The aero-engine inspection robot developed in this paper can replace human to detect engine blades and complete different detection tasks with different kinds of sensors.
Good practice for industrial heritage sites: systematization, indicators, and case
Authors: Oevermann Heike
Published: October 2019

Purpose

The purpose of this paper is to identify criteria and examples of good practice in heritage management within the specific field of UNESCO industrial heritage sites. The paper is part of a transfer-of-knowledge project between Humboldt Universität and the Zollverein Foundation (Stiftung Zollverein), responsible for the heritage management of the UNESCO Zollverein site.

Design/methodology/approach

The study employed document analysis, interviews, expert discussions and application to the field.

Findings

First, a systematization, termed the Good Practice Wheel, shows eight criteria that must be considered for good practice in heritage management. Second, indicators of good practice, discussed in the academic field, can be embedded in the suggested systematization and provide further details of how to evaluate good practice. Third, the Zollverein case shows that the systematization can be applied to practice.

Research limitations/implications

The study offers a systematization to identify and discuss good practice.

Practical implications

The practical implication is to understand better how to turn the demands of UNESCO into opportunities.

Social implications

The Good Practice Wheel includes social aspects, within community engagement and the criterion of sustainability.

Originality/value

To date, this represents the only such systematic approach to identify and implement good practice in heritage management, specifically relevant for UNESCO industrial heritage sites.
Critical factors affecting the performance of large construction projects in developing countries
Authors: Santoso Djoen San , Gallage Polwatta Gallage Madusha Piumal
Published: October 2019

Purpose

This paper aims to analyse the factors affecting the performance of large construction projects in Sri Lanka. The causes, impacts and mitigations in association with the critical factors are explored and discussed.

Design/methodology/approach

The research focuses on the evaluation and perspectives of clients and contractors of large projects in Sri Lanka. Combined quantitative and qualitative methods were applied in this research. Initially, a questionnaire survey was conducted with clients and contractors involved in large projects to evaluate the factors affecting the performance of projects and to identify the ten most critical factors. Interviews with the clients and contractors of three large projects were conducted to examine the causes and impacts of the critical factors and the approaches used to mitigate them.

Findings

Significant differences in the factors were observed for more than 40 per cent of the total factors under study, the contractors assigning more weight to most of the factors than the clients. The study identified nine internal factors and one external factor as the critical factors. Of these, seven were related to the contractors, which suggested that the contractors have greater roles in defining performance. Lack of management and technical skills of the parties involved, human capacity, lack of understanding and knowledge of the local context, changes in government policies and political interference were identified as significant causes of the critical factors.

Originality/value

The study analysed the factors affecting the performance of large projects in Sri Lanka, which, at the time of research, had just ended a 26-year-long civil war and was pushing the construction of large projects to be competitive. The challenges faced in this effort were explored as lessons learnt that might improve the efficiency and effectiveness of infrastructure development in Sri Lanka. The combined quantitative and qualitative methods applied in this study are expected to provide new insights in the project performance research, especially the interviews of the critical factors to gain an understanding on how the factors occurred and manifested themselves in real projects. The findings are, however, expected to be applicable to other developing countries that are currently aggressively developing their large infrastructure.
Of ostriches, frogs, birds and lizards
Authors: Li Chenchen , Zhang Ling Eleanor , Harzing Anne-Wil
Published: October 2019

Purpose

In response to the somewhat paradoxical combination of increasing diversity in the global workforce and the resurgence of nationalism in an era of global mobility, the purpose of this paper is to uncover how employees on international assignments respond to exposure to new cultures. Specifically, the paper aims to explicate the underlying psychological mechanisms linking expatriates’ monocultural, multicultural, global and cosmopolitan identity negotiation strategies with their responses toward the host culture by drawing upon exclusionary and integrative reactions theory in cross-cultural psychology.

Design/methodology/approach

This conceptual paper draws on the perspective of exclusionary vs integrative reactions toward foreign cultures – a perspective rooted in cross-cultural psychology research – to categorize expatriates’ responses toward the host culture. More specifically, the study elaborates how two primary activators of expatriates’ responses toward the host culture – the salience of home-culture identity and a cultural learning mindset – explain the relationship between cultural identity negotiation strategies and expatriates’ exclusionary and integrative responses, providing specific propositions on how each type of cultural identity negotiation strategy is expected to be associated with expatriates’ exclusionary and integrative responses toward the host culture.

Findings

The present study proposes that expatriates’ adoption of a monocultural identity negotiation strategy is positively associated with exclusionary responses toward the host culture and it is negatively associated with integrative responses toward the host culture; expatriates’ adoption of a multicultural identity negotiation strategy is positively associated with both exclusionary responses and integrative responses toward the host culture; expatriates’ adoption of a global identity negotiation strategy is negatively associated with exclusionary responses toward the host culture; and expatriates’ adoption of a cosmopolitan identity negotiation strategy is negatively associated with exclusionary responses, and positively associated with integrative responses toward the host culture. The following metaphors for these different types of cultural identity negotiation strategies are introduced: “ostrich” (monocultural strategy), “frog” (multicultural strategy), “bird” (global strategy) and “lizard” (cosmopolitan strategy).

Originality/value

The proposed dynamic framework of cultural identity negotiation strategies illustrates the sophisticated nature of expatriates’ responses to new cultures. This paper also emphasizes that cross-cultural training tempering expatriates’ exclusionary reactions and encouraging integrative reactions is crucial for more effective expatriation in a multicultural work environment.
Risk-mitigating effect of ESG on momentum portfolios
Authors: Kaiser Lars , Welters Jan
Published: October 2019

Purpose

Existing empirical evidence on the impact of environmental, social and governance (ESG) integration on momentum portfolios is limited. The combination of the two is relevant given the risk-mitigating effect of ESG criteria, as well as the existence of momentum crashes. As such, ESG might lend itself to reduce crash risk for momentum investors.

Design/methodology/approach

In this paper, the authors provide insight into the impact of an ESG-constrained investment universe on momentum returns. The overall investment universe is split into high and low ESG-rated segments to anylse the characteristics of momentum portfolios conditional on the ESG rating.

Findings

The authors document the existence of a momentum premium across European stocks and for a subset of high and lows ESG-rated stocks. However, absolute returns of momentum strategies are significantly lower if momentum strategies are pursued on a subset of high ESG stocks. Additionally, findings document a risk-mitigation effect of ESG for momentum portfolios with significantly lower returns for momentum portfolios based on low ESG stocks during periods of momentum crashes.

Originality/value

Research on momentum investing and the momentum premium is large and well established, yet many questions remain. A recent study by Daniel and Moskowitz (2016) has analyzed crash risk for momentum investors and identified periods of strong momentum crashes. On the other hand, the literature on ESG integration in standing investment approaches is still limited, but as demand for sustainable products is increasing, so is the demand for a better understanding of the impact of ESG integration. Consequently, the authors provide evidence on the benefits of ESG integration for momentum investors to reduce their exposure to momentum crash risk.
Leadership effectiveness of hospital managers in Iran: a qualitative study
Authors: Sarabi Asiabar Ali , Kafaei Mehr Mohammad Hossein , Arabloo Jalal , Safari Hossein
Published: October 2019

Purpose

The purpose of this paper is to investigate the factors influencing the leadership effectiveness of hospital managers in Iran.

Design/methodology/approach

Top managers (15), middle managers (10) and operational managers (5) of public, private or social security hospitals in Tehran participated in a qualitative study using semi-structured in-depth interviews. Data were recorded, transcribed and then analyzed via MAXQDA 10 software.

Findings

The findings were categorized into two main themes of internal and external factors with eight sub-themes. The most important internal factors that had an influence on the leadership of the hospital managers were intra-organizational relations, manager’s personality traits, knowledge, attitude and skills of the manager. The most important external factors included extra-organizational relations, macro-level health policies, access to special financial resources, and social, economic and political factors.

Research limitations/implications

The results call for a need to understand and analyze the socioeconomic factors influencing managers’ leadership while adopting appropriate strategies.

Practical implications

The results of the current study can help design training programs for hospital managers, and suggest criteria for appointing hospital managers across the country and this can enhance the effectiveness of their leadership. Health sector policymakers and decision makers should reform the programs that target training and empowerment of hospital managers so that the right people with the right competencies will hold such positions.

Social implications

The results of this study showed that leadership effectiveness is also influenced by social and external factors. On the other hand, the effectiveness of management leadership can play a significant role in the quality of care provided to the community, patient satisfaction and in hospital social performance through the appropriate management of all hospital resources. Such factors should also be considered in training and appointing hospital managers.

Originality/value

Although there are several studies on hospital managers’ leadership worldwide, this study is the first to investigate the leadership effectiveness of hospital managers in Iran.
Research on makers’ knowledge space construction by libraries
Authors: Liang Wei , Lu Zhangping , Liu Guifeng , Su Wencheng
Published: October 2019

Purpose

The purpose of this paper is to figure out the exact knowledge demand of makers. Furthermore, the paper aims to construct the knowledge space based on makers’ knowledge demand.

Design/methodology/approach

The first step of this research is to explore the makers’ knowledge demand by the methods of field investigation, non-interventional study and in-depth interviews. On that basis, the elements, principles, framework and mechanism of the knowledge space were discussed. The grounded theory and NVivo software were used in the data analysis.

Findings

The investigation shows that interest and competition are the main motivations for makers’ knowledge demand. The findings also indicate that the characteristics are active knowledge needs, “informal learning” preferences, divergent thinking, close community ties and interdisciplinary. According to the makers’ knowledge demand node conceptual model, the content of makers’ knowledge demand is principle knowledge, empirical knowledge and knowledge situation. Based on the above findings, the elements, principles, operation framework and inherent operation mechanism of the knowledge space construction are systemically described.

Originality/value

This study gives precise details about makers’ knowledge demand and the construction of makers’ knowledge space by libraries. This is the first research that comprehensively explores the knowledge demand of makers. The findings can help the library plan and implement the construction of makerspace, and also improve the service for makers.
The effect of pipeline layout parameters on mode and dynamic stress of “airframe-clamps-pipeline” structure
Authors: Zhang Xiantao , Liu Wei
Published: October 2019

Purpose

In the coupling of aircraft pipeline structures, current research works mainly focus on fluid-solid coupling effects or a single part of structure vibration like a pipeline. Because of the clamp, the pipe vibration caused by fluid pulsation was transmitted to the body, and the body vibration was also transmitted to the pipe structure. Thus, the relationship between the airframe and the pipeline system cannot be separated, and the influence of airframe needs to be considered when coupling structure under vibration. The paper aims to discuss these issues.

Design/methodology/approach

This paper aims to investigate the influence of pipeline layouts on airframe-clamps-pipeline (ACP) structure’s dynamic response by experiment and simulation method. First, ACP structures are established including three parts. The natural frequencies and mode shapes are obtained by hammering experiment. The mode results are in agreement with numerical simulation. By using electromagnetic vibration shaker, extinction is applied on ACP structure, and then the dynamic responses of structure can be obtained by test equipments. The influence principle of pipeline layouts is obtained by dynamic response analysis. The present study provides a method for pipeline layout design in aerospace engineering.

Findings

Under the ACP’s first-order resonance frequency excitation, the maximum stress increases when the Z-shaped pipeline bending position changes from 1/2 to 1/5. The opposite way occurs under the only pipeline resonance frequency excitation. The stress amplitudes near both sides (inner and outer) of the clamp on the plate surface change with the excitation frequency. Under the ACP’s first-order resonance frequency excitation, the outer side stress is larger than the inner side stress, but under the only pipeline resonance frequency excitation, the inner side stress is larger than the outer side stress.

Originality/value

The study of the effect of pipeline layout parameters on ACP structure provides a method for pipeline layout design in aerospace engineering.

Findings suggest that the News Library accommodates users’ social needs. However, it does not accommodate their communal needs well. The majority of students at the Penn State University Park campus, own laptops and bring them to the library when they intend to study. Personal device usage is preferable to library-provided computers per a familiarity with their personal device, access to personal files and independence of workspace.

Research limitations/implications

As this is a case study, the findings are not generalizable. This study was conducted in one library, on one campus at a 24-campus institution with over 30 libraries.

Originality/value

The mixed-methods study provides multiple views into user behaviors and expectations. The authors propose guidelines for informing the design of BYOD spaces.
Understanding causal links among the dimensions of corporate social responsibility: a framework developed using interpretive structural modelling
Authors: Alferaih Adel
Published: October 2019

Purpose

The purpose of this paper is to identify and develop a hierarchy of corporate social responsibility (CSR) dimensions and their interrelationships using interpretive structural modelling (ISM) methodology.

Design/methodology/approach

This research used ISM for framework development. ISM is, however, a sound method for developing insight into the collective understanding of the relationships between dimensions of corporate social responsibility (CSR) identified from the literature review. The steps involved in the ISM technique are structural self-interaction matrix, reachability matrix, level partitions, developing the canonical matrix, classification of dimensions for CSR and formation of ISM.

Findings

The findings indicate that company size is the only key driver for the other dimensions of CSR and is hence placed at the very bottom of the ISM model. Above this, at Level II, the key dimensions are corporate governance, diversity and corporate profile. These act as mediating dimensions between company size and the topmost level (i.e. Level III), which comprises 15 dimensions including CSR.

Research limitations/implications

Some limitations of this research indicate the need for further research. First, the proposed ISM model has only been conceptualised and has not been empirically tested using primary data. Future research is needed to validate the model in whole or part, to understand the perceived CSR of a company. Second, the methodology was limited to the use of ISM to model the CSR dimensions; it was not extended to fuzzy MICMAC analysis or to interpretive ranking.

Practical implications

The proposed ISM-based model for the identification and ranking of CSR dimensions and their interrelationships offers decision makers and practitioners a more convincing representation of the problems affecting the exploration of CSR dimensions. The utility of the proposed ISM method lies in imposing order and direction on the complexity of relationships among these dimensions, which will help top management and decision makers to better use their available resources in optimising their CSR practices. The framework allows policymakers to effectively incorporate these dimensions into their practising of CSR.

Originality/value

This is the first research on CSR to conceptualise a framework of causal interactions among its key dimensions using ISM methodology.
A model for examining the role of the Internet of Things in the development of e-business
Authors: Esmaeilpour Ghouchani Babak , Jodaki Susan , Joudaki Maryam , Balali Alireza , Rajabion Lila
Published: October 2019

Purpose

Nowadays, the Internet of Things (IoT) offers new intelligent services and business model opportunities by extending the internet connectivity into physical devices and daily objects. Recently, this technology has had a deep impact on all the aspects of human societies from industry to management and business. Therefore, the purpose of this paper is to predict the impact of using IoT services on the development of electronic business (e-business).

Design/methodology/approach

For evaluating the model’s elements, a questionnaire was designed. It was revised by experts with significant experiences. For statistical analysis, SmartPLS 3.2 is used.

Findings

The findings have confirmed the validity of the proposed model. The results also have indicated that the quality of IoT services (scalability, availability, reliability and ease of use), security of IoT services (trust, reputation, privacy and encryption) and IT knowledge of users (usage skills, awareness, experience and accuracy) have a positive and significant impact on development of e-business. Furthermore, the obtained results have revealed that the operating cost of IoT services (transmission time, storage capacity, functionality and stability) is significantly influenced by the development of e-business.

Research limitations/implications

By capturing a number of important factors in the proposed model, this study can provide a significant theoretical influence for researchers in the related area of interest. In fact, this study provides a worthwhile direction by assessing e-business performance, which, so far, has not been well assessed in many developing countries.

Practical implications

From a practical perspective, the statistical results support the crucial role of the following factors: quality of IoT services, the security of IoT services, operating cost of IoT services and IT knowledge of users. Hence, aspects relating to these factors must be the focus of attention of any organization in their endeavor to development of e-business.

Originality/value

This study meaningfully contributes to the knowledge and literature by focusing more on development e-business and IoT as original technology for further understanding, investigating other important features and applying advanced statistical analyses technique. By doing so, this study was able to develop the current understanding regarding the main aspects of development e-business and IoT services.
Clinical supervision in older adult mental health services
Authors: Merizzi Alessandra
Published: October 2019

Purpose

The purpose of this paper is to explore how supervision is applied in the context of National Health Service services for older adults, with particular regard to the profession of clinical psychology and psychotherapy.

Design/methodology/approach

The clinical supervision theories that are considered in this exploration are the Seven-Eyed Model (Hawkins and Shohet, 2012) and the Cyclical Model (Page and Wosket, 2015). The discussion also integrates an overview of psychological dynamics as presented by the existing literature with the author’s reflections on the influence of ageing stereotypes in the therapeutic work with older adults.

Findings

The theoretical models of clinical supervision considered can offer a robust framework and pathway for supervisory work in psychology and psychotherapy for older people. However, this alone seems insufficient and needs to be combined with the supervisor’s knowledge on psychology of ageing as well as their own self-reflection on internalised ageing stereotypes.

Practical implications

The paper suggests a need for health care professionals, providing clinical supervision on older adult therapeutic work, to be familiar with the aspects analysed.

Originality/value

Clinical supervision handbooks overlook aspects related to age as an issue of difference. This paper adds value to the clinical work with older people through a novel attempt to link implications of ageing stereotypes with the therapeutic and supervisory practice.
