Multi-objective optimal design of flexible-joint parallel robot
Authors: Lara-Molina Fabian Andres , Dumur Didier , Assolari Takano Karina 
Published: October 2018

Purpose
This paper aims to present the optimal design procedure of a symmetrical 2-DOF parallel planar robot with flexible joints by considering several performance criteria based on the workspace size, dynamic dexterity and energy of the control.

Design/methodology/approach
Consequently, the optimal design consists in determining the dimensional parameters to maximize the size of the workspace, maximize the dynamic dexterity and minimize the energy of the control action. The design criteria are derived from the kinematics, dynamics, elastodynamics and the position control law of the robot. The analysis of the design criteria is performed by means of the design space and atlases.

Findings
Finally, the multi-objective design optimization derived from the optimal design procedure is solved by using multi-objective genetic algorithms, and the results are analyzed to assess the validity of the proposed approach.

Originality/value
An alternative approach to the design of a planar parallel robot with flexible joints that permits determining the structural parameters by considering kinematic, dynamic and control operational performance.
A gradient-based shape optimization scheme via isogeometric exact reanalysis
Authors: Ding Chensen , Cui Xiangyang , Huang Guanxin , Li Guangyao , Tamma K.K. , Cai Yong 
Published: October 2018

Purpose
This paper aims to propose a gradient-based shape optimization framework in which traditional time-consuming conversions between computer-aided design and computer-aided engineering and the mesh update procedure are avoided/eliminated. The scheme is general so that it can be used in all cases as a black box, no matter what the objective and/or design variables are, whilst the efficiency and accuracy are guaranteed.

Design/methodology/approach
The authors integrated CAD and CAE by using isogeometric analysis (IGA), enabling the present methodology to be robust and accurate. To overcome the difficulty in evaluating the sensitivities of objective and/or constraint functions by analytic method in some cases, the authors adopt the finite difference method to calculate these sensitivities, thereby providing a universal approach. Moreover, to further eliminate the inefficiency caused by the finite difference method, the authors advance the exact reanalysis method, the indirect factorization updating (IFU), to exactly and efficiently calculate functions and their sensitivities, which guarantees its generality and efficiency at the same time.

Findings
The proposed isogeometric gradient-based shape optimization using our IFU approach is reliable and accurate, as well as general and efficient.

Originality/value
The authors proposed a gradient-based shape optimization framework in which they first integrate IGA and the proposed exact reanalysis method for applicability to structural response and sensitivity analysis.
Construction and initial validation of the E-Work Life Scale to measure remote e-working
Authors: Grant Christine Anne , Wallace Louise M. , Spurgeon Peter C. , Tramontano Carlo , Charalampous Maria 
Published: October 2018

Purpose
The purpose of this paper is to develop and provide initial validation for the new E-Work Life (EWL) Scale. This measure assesses a range of theoretically relevant aspects of the e-working experience related to four main areas: job effectiveness, relationship with the organisation, well-being and work-life balance.

Design/methodology/approach
This study presents structured item development. Internal validity and reliability were tested on a sample of 260 e-workers (65 per cent female, age range 25–74). Correlations of the EWL scale with a measure of general health were tested on a subsample of 119 workers to provide initial evidence of construct validity.

Findings
Exploratory factor analysis supported a 17-item scale assessing four factors: work-life interference, productivity, organisational trust and flexibility. Individual well-being was measured and a pattern of significant correlations against four factors as indicators of general health were found, including mental health and vitality.

Research limitations/implications
A new sample would confirm the strength of the EWL scale alongside further tests of validity. Coping strategies related to the scale would aid mapping of individual competencies for remote e-working to promote e-workers’ self-management, management style and organisational policy.

Practical implications
The EWL scale helps organisations to evaluate and support the well-being of remote e-workers. It provides measurement on three levels: individual, supervisory and organisational, whereby practical strategies for improvement can be linked to the scale.

Originality/value
The EWL scale completes a gap in the research by providing a measure aiding organisations to evaluate and support remote e-worker well-being.
Facing disaster: the great challenges framework
Authors: Torres Phil 
Published: October 2018

PurposeThis paper provides a detailed survey of the greatest dangers facing humanity this century. It argues that there are three broad classes of risks – the “Great Challenges” – that deserve our immediate attention, namely, environmental degradation, which includes climate change and global biodiversity loss; the distribution of unprecedented destructive capabilities across society by dual-use emerging technologies; and value-misaligned algorithms that exceed human-level intelligence in every cognitive domain. After examining each of these challenges, the paper then outlines a handful of additional issues that are relevant to understanding our existential predicament and could complicate attempts to overcome the Great Challenges. The central aim of this paper is to constitute an authoritative resource, insofar as this is possible in a scholarly journal, for scholars who are working on or interested in existential risks. In the author’s view, this is precisely the sort of big-picture analysis that humanity needs more of, if we wish to navigate the obstacle course of existential dangers before us.Design/methodology/approachComprehensive literature survey that culminates in a novel theoretical framework for thinking about global-scale risks.FindingsIf humanity wishes to survive and prosper in the coming centuries, then we must overcome three Great Challenges, each of which is sufficient to cause a significant loss of expected value in the future.Originality/valueThe Great Challenges framework offers a novel scheme that highlights the most pressing global-scale risks to human survival and prosperity. The author argues that the “big-picture” approach of this paper exemplifies the sort of scholarship that humanity needs more of to properly understand the various existential hazards that are unique to the twenty-first century.

Published: October 2018

Purpose
A new coupled model is developed to simulate the interaction between fluid droplet collisions on discrete particles (DPs) by using mathematic function.

Design/methodology/approach
In this model, the smoothed particle hydrodynamics (SPH) is used based on the kernel function and the time step which takes into consideration to the fluid domain in accordance with the discrete element method (DEM) with resistance function. The interaction between fluid and DPs consists of three parts, which are repulsive force, viscous shear force and attractive force caused by the capillary action. The numerical simulation of droplet collision on DPs presents the whole process of droplet motion. Otherwise, an experimental data were conducted to record the realistic process for verification.

Findings
The comparison result indicated that the numerical simulation is capable of capturing the entire process for droplet collision on DPs.

Research limitations/implications
However, based on the difference of experimental environment, type of the DP and setups, the maximum spreading dimeters of could not fit the experimental data exactly.

Originality/value
In sum, the coupled SPH-DEM method simulation shows that the coupled model of SPH-DEM developed an entire effectiveness process for fluid–solid interaction problem.

Authors: Sweis Rateb , Moarefi Alireza , Amiri Mahmood Hosseini , Moarefi Soad , Saleh Rawan 
Published: October 2018

Purpose
The international energy agency states that the world’s primary energy needs are expected to grow to 55 per cent until 2030. Therefore, oil and gas industry as the main energy source will be more crucial where building or advancing new capacities is required. Because the reports highlight the delay as a recurring problem, thereby, more in-depth investigation to find out the main contributing causes is needed.

Design/methodology/approach
Root cause analysis (RCA) was applied to identify, rank, analysis and categorize the main sources of this problem.

Findings
Based on RCA procedure; Pareto analysis showed that 84.7 per cent of the delay is because: the radar chart indicated no difference in perception of the participants regarding the importance of the root causes, correlation analysis suggested strong relationship among the participants and the cause-and-effect diagram emphasized more on operational, human and equipment categories, which in total account for 51.86 per cent of the delay.

Originality/value
The risk planners of large-scale projects can consider these root causes as the main items to analysis, monitor and control, as they are vitally important for project success.

Authors: Akram Vaseem , Jangam Bhushan Praveen , Rath Badri Narayan 
Published: October 2018

PurposeThis paper aims to investigate whether improvement in human capital can foster energy conservation by reducing the energy consumption in India using annual data from 1980 to 2014. Further, this study examines the relationship between human capital and various forms of energy consumption such as electricity, coal, natural gas, hydrocarbon gas and petroleum consumption.Design/methodology/approachTo attain the objective, the study investigates this relation through the auto-regressive distributed lag model (ARDL) technique to find a long-run and short-run relationship. Second, to check the robustness of the results, the authors use alternative econometric methods such as dynamic ordinary least squares and fully modified dynamic ordinary least squares.FindingsThe results reveal a negative relationship between human capital and energy consumption, which implies that improvement in human capital lowers the energy consumption and various forms energy consumption, except for petroleum consumption. The results derived from ARDL show that there exists a long-run and short-run association between human capital and energy consumption. The results are consistent across the econometric techniques.Practical implicationsBecause G20 countries including India aim at reducing carbon emission to a certain level, this study provides an insight that by emphasizing on human capital, India can reduce energy consumption, which would foster energy conservation.Originality/valueTo the best of the authors’ knowledge, this the first study in India which attempts to examine the effect of human capital on energy consumption and its various forms.
Start-up motives and challenges facing female entrepreneurs in Tanzania
Authors: Isaga Nsubili 
Published: October 2018

Purpose
Research on women-owned business is more extensive in developed countries than in developing countries and such one cannot compare the results. This paper aims to examine the motives of women in Tanzania (a less developed country) to start their own businesses and the challenges they faced in running their businesses.

Design/methodology/approach
Based on 400 response to a semi-structured questionnaire and in-depth interview with 20 female entrepreneurs. Subsequently, descriptive and factors analysis were performed to analyze the data

Findings
Based on survey responses, the primary reason for starting a business was to create employment for the woman herself. Other motives include supplementing income and enabling women to be able to do the kind of work they wanted to do. According to the factor analysis, female entrepreneurs are driven more by push factors than pull factors. The most serious problems faced by female entrepreneurs are lack of access to finance, gender-related problems and social and cultural commitments.

Research limitations/implications
The sample was selected from urban areas of only three regions, out of 26 regions in Tanzania. Researchers may extend the study to other regions; also, the non-probability sampling method used in this study essentially means that there is a limitation to the extent to which the research findings can be generalized to the rest of the population of female entrepreneurs in Tanzania.

Practical implications
Policy makers, financial institutions and all organization that have a stake on development on female entrepreneurs in Tanzania should design policies and programs that encourage and promote the creation and growth of businesses. Collective efforts from the government, public and private institutions and NGOs are needed to eliminate the challenges, especially gender-related problems.

Practical implications
By studying female owner-managers’ motivations and constraints, the author suggests that to a greater extent, gender-related problems, social and cultural commitments and access to finance and networks are the constraints faced by female entrepreneurs.

Originality/value
The research on female entrepreneurs in the context of Tanzania is scarce, this study responds to a need of better understanding women motivations and constraints. By studying these factors, this study shows that startup motives and constraints faced by female entrepreneurs are unique to different contexts.

Authors: Kautish Pradeep , Sharma Rajesh 
Published: October 2018

PurposeThe purpose of this paper is to study the underlying relationships among two distinct forms of consumer values, namely, instrumental and terminal values, fashion consciousness and behavioural intentions in the context of online fashion apparel retail sector.Design/methodology/approachA conceptual model and subsequent measurement scale were developed, grounded on in-depth review of the extensive literature and validated with customers engaged in online shopping of fashion apparels. The model was empirically examined, and a total of 395 responses were gathered from an online survey administered at a northeastern university in India. The model was validated using structural equation modelling, and a two-step approach suggested by Anderson and Gerbing (1988) was used to evaluate the measurement and structural models for the research.FindingsThe results of the study indicate that instrumental and terminal values significantly affect fashion consciousness, and fashion consciousness has a significant impact on behavioural intentions as well. The research brings out that fashion consciousness acts as a partial mediator between instrumental/terminal values and behavioural intentions. It is noteworthy that compared to terminal values instrumental values display a greater influence on both the variables fashion consciousness and behavioural intentions.Research limitations/implicationsThe conclusion of present research will notably assist the fashion retailers, online marketing researchers and experts understand the importance of terminal and instrumental values in increasing fashion consciousness, leading to strategically design campaigns for promoting and instigate consumers’ positive behavioural intentions in the best interest of the online fashion retail sector.Practical implicationsThe study results provide suggestions for competitive marketing strategies for online fashion companies operating in the emerging markets like India.Originality/valueThe present study is first of its kind attempt to use Rokeach’s (1973) two-dimensional measure of human values, in order to discover the terminal and instrumental values relationship and their influence on fashion consciousness and behavioural intentions in the online fashion retail industry.

Authors: Abbasian Saeid 
Published: October 2018

PurposeThe purpose of this paper is to gain more insight into the phenomenon of solo travel to city destinations and attain more knowledge on the topic.Design/methodology/approachThe study employed a questionnaire consisting of qualitative and quantitative items. In all, 21 individuals (12 women, 9 men) responded.FindingsThe most important reason for solo travel was their own free choice and in some cases, difficulty finding companions. Their activities at the destinations were mostly visiting attractions followed by visiting friends, shopping, walking, eating at restaurants, learning the language, working, etc. They mostly mentioned advantages but also some disadvantages with solo travelling. Their experiences, especially with the people in the host destinations, have been positive and they show overall satisfaction with their visit. A predominant share of the interviewees showed a kind of loyalty to one or more specific city destinations and wished to revisit them again and again.Practical implicationsThe current study might have some implications for city tourism developers/destination developers, travel agencies, national or regional tourism boards and tour operators in major urban areas and cities. Especially, this study has a practical contribution to the city tourism practitioners and gives them more insight in what values, attitudes, perceptions, expectations and motivations the solo travellers might have before or while they visit their cities. The study also has implications for potential solo travellers seeking more knowledge and information on the issue.Originality/valueThe phenomenon of solo travel to city destinations is an unresearched topic in Sweden. This exploratory study is the first in Sweden to focus on solo travellers visiting city destinations.

Authors: Zhang Yanqin , Zhang Zhiquan , Kong Xiangbin , Li Rui , Jiang Hui 
Published: October 2018

Purpose
The purpose of this paper was to obtain the lubrication characteristics of heavy hydrostatic bearing in heavy equipment manufacturing industry through theoretical analysis and numerical simulation.

Design/methodology/approach
This paper discusses the influence of oil film thickness variation on velocity field, outlet-L and outlet-R flow velocity under the hydrostatic bearing running in no-load 0 N, load 400 KN, full load 1,500 KN and rotating speeds of 10 r/min, 20 r/min, 30 r/min, 40 r/min, 50 r/min and 60 r/min, by using dynamic mesh technology and FLUENT software.

Findings
When the working table rotates clockwise, in the change process of oil film thickness, the fluid flow pattern of the lubricating oil at the edge of the sealing oil is the rule of laminar flow, and the oil cavity has a vortex. The outlet-R flow velocity becomes higher and higher by increasing the bearing load and working table speed, and the flow velocity increases with the decrease in oil film thickness; the outlet-L flow velocity increases with the decrease in oil film thickness under low rotating speed (less than 10 r/min) condition and decreases with the decrease of oil film thickness under high rotating speed (more than 60 r/min) condition.

Originality/value
The influence of the oil film thickness on the flow state distribution of the oil film was analyzed under different working conditions, and the influence rules of oil film thickness on the flow velocity of hydrostatic bearing oil pad was obtained by using dynamic mesh technology.
