Authors: Guo Pengyue , Zhang Zhijing , Shi Lingling , Liu Yujun 
Published: June 2021

Purpose
The purpose of this study was to solve the problem of pose measurement of various parts for a precision assembly system.

Design/methodology/approach
A novel alignment method which can achieve high-precision pose measurement of microparts based on monocular microvision system was developed. To obtain the precise pose of parts, an area-based contour point set extraction algorithm and a point set registration algorithm were developed. First, the part positioning problem was transformed into a probability-based two-dimensional point set rigid registration problem. Then, a Gaussian mixture model was fitted to the template point set, and the contour point set is represented by hierarchical data. The maximum likelihood estimate and expectation-maximization algorithm were used to estimate the transformation parameters of the two point sets.

Findings
The method has been validated for accelerometer assembly on a customized assembly platform through experiments. The results reveal that the proposed method can complete letter-pedestal assembly and the swing piece-basal part assembly with a minimum gap of 10 µm. In addition, the experiments reveal that the proposed method has better robustness to noise and disturbance.

Originality/value
Owing to its good accuracy and robustness for the pose measurement of complex parts, this method can be easily deployed to assembly system.
Relative exploration orientation and real options reasoning: survey evidence from Denmark
Authors: Jensen Claus Højmark , Kristensen Thomas Borup 
Published: June 2021

PurposeThis paper aims to extend the understanding of how real options reasoning (ROR) is associated with downside risk and how a firm’s portfolio (explore and exploit) of investment activities affects managers’ ability to effectively apply ROR in relation to downside risk.Design/methodology/approachThe survey method is used. It is applied to a population of Danish firms, which in 2018 had more than 100 employees. The chief financial officer was the target respondent.FindingsThis study finds that a higher level of ROR is associated with lower levels of downside risk. ROR’s association with lower levels of the downside risk is also moderated by the level of relative exploration orientation in a negative direction.Originality/valueThe field of ROR research on downside risk and portfolio subadditivity has been dominated by research focused on multinationality. This paper extends extant literature on ROR by studying ROR as a multidimensional construct of firm action, which is associated with lower levels of downside risk, also when studied outside of a multinationality setting. This is the case when ROR is implemented as a complete system. This paper also applies a framework of exploitation and exploration to show that findings on subadditivity in options portfolios caused by asset correlations extend outside the scope of multinationality and into one of product/service innovation.

Authors: Park Soyeon , Cho Kihun 
Published: June 2021

Purpose
This study aims to investigate and compare mobile and desktop user search behaviours of the 1300K site, a Korean shopping search engine, by using transaction log analysis.

Design/methodology/approach
Transaction logs of 1300K site were collected over a three months’ period, from 1 January to 31 March 2018. The data set of this study consists of 1,149,690 desktop queries, 2,346,938 mobile queries, 2,481,747 desktop browsing activities and 2,550,309 mobile browsing activities. This study quantitatively analyses transaction log of 1300K site.

Findings
The results of this study show that mobile usage is higher than desktop usage: there are more mobile sessions than desktop sessions and the number of mobile queries is more than double of desktop queries. Overall, mobile query search behaviours are more simple, targeted and focused than desktop query search behaviours. Also, mobile browsing behaviours are more simple and passive than desktop browsing behaviours. However, mobile click behaviours are more active than desktop click behaviours.

Originality/value
To the best of the authors’ knowledge, this study appears to be the first of its type in Korea that compared search behaviours of a large number of users on desktop computers and mobile phones. To identify various characteristics of user search behaviours, this study analyses users’ directory browsing behaviour and click behaviour as well as query search behaviour. The results of this study can be implemented to address the effective improvement and development of search services and interfaces for different devices.
Incorporation of indigenous archives into Limpopo archives repository: a case of Venda indigenous archives
Authors: Netshakhuma Nkholedzeni Sidney 
Published: June 2021

Purpose
This study aims to assess the Venda indigenous archives incorporation into the Limpopo Provincial archives to promote archives decolonisation.

Design/methodology/approach
This research is based on a qualitative research method. Interviews conducted with the 10 Limpopo Provincial Archivists and 25 community leaders based in the Venda area were conducted. The semi-structured interview was used to collect data.

Findings
It is a South African constitutional mandate for each province to manage its archives. As the former Venda was now part of the Limpopo province, its archives were incorporated into the Limpopo Provincial Archives. The Venda archives incorporation to the Limpopo Provincial Archives did not consider the will of a community member to travel a long distance. Furthermore, challenges faced by archivists such as lack of skills and knowledge to process archival materials, lack of funding and participation in the incorporation of archives materials.

Research limitations/implications
This research confines itself to the Venda indigenous archives created from 1979 to 1993.

Practical implications
This paper addresses archives decolonisation.

Social implications
The paper has the potential to demonstrate the value of the indigenous archive.

Originality/value
The study can be replicated for other research practices. This case study can be implemented in other parts of the world that face similar circumstances so regarding the transfer of archives and the challenges faced to maintain community knowledge and make them accessible.
Perceived barriers to career progression amongst female students: evidence from India and the United Arab Emirates
Authors: Biju Seena , Shetty Khyati , Fitzsimmons Jason R. 
Published: June 2021

Purpose
The purpose of this paper is to explore the perceptions of barriers to career progression among female university students. While significant literature has examined career enhancement in the context of employed women, little work has explored the perceptions of future career challenges of females about to enter the workforce and embark on their careers. This study derives its motivation from research findings that confirm that women need additional focused preparation for career advancement opportunities.

Design/methodology/approach
The study used a sample of 484 Indian female university students located in the United Arab Emirates and India. The study uses the established Career Pathways Survey scale (Smith et al., 2012a) to measure the four dimensions Denial, Acceptance, Resignation and Resilience to career progression. Structural equation modeling was used to model the four constructs as indicators of perceived barriers to progress.

Findings
The study finds that among the female students about to embark on their career journey, there is a strong desire toward achieving career success. The model is validated by the use of a structural equation model, and findings indicate that there is a strong sense of Resilience and an element of uncertainty about whether perceived career progression will be satisfying overall. No significant differences were observed in the perceptions across the two geographical locations. The findings suggest that continued efforts in preparing female graduates for career success are warranted.

Practical implications
The Career Pathways Survey may be a useful method to assist young women in identifying their career goals prior to entering the workforce. Interventions through training programs during their higher education may be beneficial in addressing perceptions that might hinder their later career growth.

Originality/value
This paper contributes to the understanding of the perceived barriers to career progression for women. Prior research has concentrated on career progression in the context of employed women. This study extends that work to understand the perceptions of women about to embark on their career journey.
Susceptibility of falling behind current medical knowledge among health-care professionals: the extended parallel process model
Authors: Naeem Salman Bin , Bhatti Rubina , Ahmad Khurshid , Rafi Muhammad 
Published: June 2021

Purpose
The purpose of this paper is to appraise the possible response outcomes (no response, fear control or danger control) of a fear-based message on falling behind current medical knowledge among health-care professionals (HCPs).

Design/methodology/approach
This study was conducted using a quantitative research design. A cross-sectional survey was carried out in 2,873 health-care facilities across 36 districts of Punjab. The Extended Parallel Process Model (EPPM) provided a theoretical framework for this study. The important components to EPPM such as threat, efficacy and outcomes were used to collect the data. The collected data was analyzed using Statistical Package for Social Sciences (SPSS) version 22.

Findings
HCPs perceived high susceptibility and threat of falling behind current medical knowledge. A majority of the HCPs were at the danger control process and engaged in a behavior that is recommended for adaptive behavioral changes. Clinical experience and enrollment in post-graduation programs (e.g. FCPS, MCPS) were significant factors as to HCPs’ perceived response efficacy.

Research limitations/implications
The responses were obtained using a structured questionnaire, which is always subject to respondents’ personal biases and ability to understand the question’s statement.

Practical implications
This study has important implications in terms of introducing promotional, educational and logistical interventions that could help in HCPs overcoming the fear of falling behind current medical knowledge and develop productive and adoptive information behavior thus improving patient care and outcome.

Originality/value
This is the first large-scale empirical study in Pakistan that measured the level of threat and efficacy among HCPs using the EPPM. It proposes a framework for developing long-lasting adaptive information behavioral changes that may result in informed patient care and better decision-making.
An interactive query-based approach for summarizing scientific documents
Authors: Bayatmakou Farnoush , Mohebi Azadeh , Ahmadi Abbas 
Published: June 2021

Purpose
Query-based summarization approaches might not be able to provide summaries compatible with the user’s information need, as they mostly rely on a limited source of information, usually represented as a single query by the user. This issue becomes even more challenging when dealing with scientific documents, as they contain more specific subject-related terms, while the user may not be able to express his/her specific information need in a query with limited terms. This study aims to propose an interactive multi-document text summarization approach that generates an eligible summary that is more compatible with the user’s information need. This approach allows the user to interactively specify the composition of a multi-document summary.

Design/methodology/approach
This approach exploits the user’s opinion in two stages. The initial query is refined by user-selected keywords/keyphrases and complete sentences extracted from the set of retrieved documents. It is followed by a novel method for sentence expansion using the genetic algorithm, and ranking the final set of sentences using the maximal marginal relevance method. Basically, for implementation, the Web of Science data set in the artificial intelligence (AI) category is considered.

Findings
The proposed approach receives feedback from the user in terms of favorable keywords and sentences. The feedback eventually improves the summary as the end. To assess the performance of the proposed system, this paper has asked 45 users who were graduate students in the field of AI to fill out a questionnaire. The quality of the final summary has been also evaluated from the user’s perspective and information redundancy. It has been investigated that the proposed approach leads to higher degrees of user satisfaction compared to the ones with no or only one step of the interaction.

Originality/value
The interactive summarization approach goes beyond the initial user’s query, while it includes the user’s preferred keywords/keyphrases and sentences through a systematic interaction. With respect to these interactions, the system gives the user a more clear idea of the information he/she is looking for and consequently adjusting the final result to the ultimate information need. Such interaction allows the summarization system to achieve a comprehensive understanding of the user’s information needs while expanding context-based knowledge and guiding the user toward his/her information journey.
Analysis of factors affecting the realization of right to adequate housing in Iran: developing an interpretive-structural model
Authors: Zarghamfard Moslem , Meshkini Abolfazl 
Published: June 2021

Purpose
Access to adequate housing represents a right entitled to any individual, as has been acknowledged by all states around the world. In Iran, despite the declaration of this right as per the Article 31 of Iran’s Constitution, it is yet to be realized. The purpose of this study is to developing a model for realization of the right to the adequate housing.

Design/methodology/approach
The present research was performed through a guided qualitative method. Structural-interpretative modeling was performed to present the model of right to adequate housing, and Mic Mac analysis was conducted for clustering the identified factors. Statistical population was composed of housing experts, with the samples taken via purposive sampling technique.

Findings
Based on the findings, the following factors were found to impose the largest effects on the realization of the right to adequate housing: alignment with ideology and beliefs of society; governance structure related arrangements; social structure related arrangements; improving security of tenure; justice in tenure; and local requirements.

Practical implications
Findings of this research contributes to increasing the awareness of the housing officials about their policies, reminding them the necessity of revisiting their routines for policy-setting. Indeed, they must switch from centralized policymaking to localized (provincealization) policymaking.

Originality/value
To the best of authors’ knowledge, this research is the first to investigate the right to adequate housing in Iran, elaborating on the relationship between relevant theories and practical issues.

Authors: Piroozi Bakhtiar , Abdullah Farman Zahir , Mohamadi-Bolbanabad Amjad , Safari Hossein , Amerzadeh Mohammad , Rezaei Satar , Moradi Ghobad , Ansari Masoumeh , Afkhamzadeh Abdorrahim , Gholami Jamshid 
Published: June 2021

Purpose
The purpose of this study is to investigate the status of perceived need, seeking behavior and utilization of health services in the elderly population of Sanandaj (west of Iran).

Design/methodology/approach
This is a cross-sectional study conducted on 800 elderly people in Sanandaj. Subjects were selected using multistage sampling and data were collected using self-report questionnaires. A multivariate logistic model with odds ratios (ORs) was used to determine the relationship of independent variables with seeking perceived need. Also, the concentration index was used to measure the inequality in using health services.

Findings
The perceived need for outpatient (during the last 30 days) and inpatient health-care services (during the past 12 months) was 69.7% and 29.7%, respectively. Among them, the unmet need for outpatient and inpatient health-care services was 46.6% and 17%, respectively. Having health insurance (adjusted OR 12.08; 95% confidence interval [CI] 1.04–140.11), middle economic status (adjusted OR 5.18; 95% CI 1.30–20.51) and being in an age group of 65–70 years (adjusted OR 7.60; CI 1.42–40.61) increased the chance of seeking inpatient care. Also, being in an age group of 60–65 years (adjusted OR 0.41; 95% CI 0.18–0.95) reduced the chance of seeking outpatient care. There was also a pro-rich inequality in using outpatient health services.

Originality/value
The elderly population suffers from unmet health-care needs, especially in outpatient services. The most important reason for not seeking outpatient and inpatient services was financial barriers and self-medication, respectively. So, designing targeted policies and interventions to address barriers in the conversion of need to demand in the elderly population is essential.
Fabrication of high-aspect-ratio grooves with high surface quality by using femtosecond laser
Authors: Zhang Ru , Huang Chuanzhen , Wang Jun , Zhu Hongtao , Liu Hanlian 
Published: June 2021

Purpose
The purpose of this study is to fabricate high-aspect-ratio grooves with high surface quality by femtosecond laser (FS) to improve the machinability of silicon carbide (SiC) and optimize the process parameters in micromechanical applications.

Design/methodology/approach
Four contrast experiments are reported to characterize the FS laser grooving process for SiC with polarization direction, crystal orientation, multi-pass scanning and z layer feed, respectively. The effects of different experimental conditions on the groove characteristics, material removal rate (MRR), aspect ratio, heat affected zone (HAZ) and surface roughness Ra are analyzed.

Findings
The influence of increasing laser fluence and multi-scanning pass on the groove depth is greater than on the groove width. The MRR, aspect ratio, HAZ and Ra increased with the increase of laser fluence and multi-scanning pass. The direction of laser polarization affects the direction of hot electron injection but has little effect on the material characteristics. FS laser ablation is an isotropic process and there is no obvious change in different crystal orientations. The z-layer feed can significantly increase the groove width and depth and reduce HAZ and Ra. The maximum aspect ratio of 82.67% was fabricated.

Originality/value
The results contribute to the understanding of the removal mechanism and reduce the friction of the microfluidic device and improve the flowability in the FS laser ablation of SiC. This paper provides suggestions for the selection of suitable process parameters and provides a wider possibility for the application of micro-texture on SiC.

Authors: Costa Danilo de Melo 
Published: June 2021

PurposeChina has invested massively in higher education, reaching a mass system, envisaging, as a next step, reaching a universal system. Brazil is still an elite system but needs to create adequate public policies to migrate to a mass system. The purpose of this article is to analyze the paradigms for a mass educational system, with regard to the quality of education offered, and the prospects for achieving a universal system, with Brazil and China as a reference.Design/methodology/approachThe author applied an exploratory and qualitative method, through categorical content analysis. The data were collected through nine interviews with government managers, 15 unstructured (open) questionnaires to specialists in higher education and four student leadership.FindingsThe results indicate that the change from an elite system to a mass system impacts quality, as there is an inevitable change in experience. However, this modification does not testify against the mass system, as it is necessary for a nation to pass through it and structure itself adequately in order to reach the universal system, a path desired by both countries.Originality/valueThe study presented the reflections observed by the migration from the elite system to the mass system from the main stakeholders of the system in China and the prospects for Brazil to become a mass system. Additionally, it presented the perspectives for both countries to achieve the desired universal system.
