SenU-PTM: a novel phrase-based topic model for short-text topic discovery by exploiting word embeddings
Authors: Lu Heng-Yang , Zhang Yi , Du Yuntao 
Published: April 2021

PurposeTopic model has been widely applied to discover important information from a vast amount of unstructured data. Traditional long-text topic models such as Latent Dirichlet Allocation may suffer from the sparsity problem when dealing with short texts, which mostly come from the Web. These models also exist the readability problem when displaying the discovered topics. The purpose of this paper is to propose a novel model called the Sense Unit based Phrase Topic Model (SenU-PTM) for both the sparsity and readability problems.Design/methodology/approachSenU-PTM is a novel phrase-based short-text topic model under a two-phase framework. The first phase introduces a phrase-generation algorithm by exploiting word embeddings, which aims to generate phrases with the original corpus. The second phase introduces a new concept of sense unit, which consists of a set of semantically similar tokens for modeling topics with token vectors generated in the first phase. Finally, SenU-PTM infers topics based on the above two phases.FindingsExperimental results on two real-world and publicly available datasets show the effectiveness of SenU-PTM from the perspectives of topical quality and document characterization. It reveals that modeling topics on sense units can solve the sparsity of short texts and improve the readability of topics at the same time.Originality/valueThe originality of SenU-PTM lies in the new procedure of modeling topics on the proposed sense units with word embeddings for short-text topic discovery.

Authors: Chang Yuan-Chieh , Chiu Wen-Hong , Wang Jian-Hang , Teng Min-Jun 
Published: April 2021

PurposeThe paper proposes customer involvement can be considered an organization-level construct of knowledge creation in the new process development. Specifically, the paper evaluates three distinct organizational practices as knowledge antecedents – competitor orientation, social network and internal coordination – that can facilitate the adoption of customer involvement in the process innovation development.Design/methodology/approachThe paper empirically tests this theory for 2,000 firms that are stratification sampled from a population of 33,844 Taiwanese firms, and a data set of 170 valid questionnaires is collected. The questionnaire was mainly modified from a Kim and Kim (2010) measure which was designed based on the 3rd edition of the Oslo Manual OECD/Eurostat 2005. The concept of customer involvement in new service development proposed by Alam (2002) was also applied to the questionnaire.Findings(1) The antecedents of customer involvement, which include competitor orientation, external social networks and internal coordination, function as a determinant to nourish customer involvement. (2) Customer involvement significantly positively mediates the relationship between knowledge antecedents and new process performance. (3) Customer involvement is a crucial knowledge creation for improving the new process innovation performance in manufacturing firms.Originality/valueTwo basic tenets of theory building serve as the foundation of the model in this paper. First, research on customer involvement is augmented by showing that customer involvement can emerge as a shared perception among organizational members that is distinct from individual-level involvement. Moreover, customer involvement in process innovation can help firms manage their knowledge and further enhance firm performance. Second, the knowledge management model provides a key lens through which researchers can take a process-oriented view that focuses on customer involvement as a unique capability that firms can develop in process innovation.

Published: April 2021

PurposeBuildings are responsible for the consumption of around 40% of energy in the world and account for one-third of greenhouses gas emissions. In Saudi Arabia, residential buildings consume half of total energy among other building sectors. This study aims to explore the impact of sixteen envelope variables on the operational and embodied carbon of a typical Saudi house with over 20 years of operation.Design/methodology/approachA simulation approach has been adopted to examine the effects of envelope variables including external wall type, roof type, glazing type, window to wall ratio (WWR) and shading device. To model the building and define the envelope materials and quantify the annual energy consumption, DesignBuilder software was used. Following modelling, operational carbon was calculated. A “cradle-to-gate” approach was adopted to assess embodied carbon during the production of materials for the envelope variables based on the Inventory of Carbon Energy database.FindingsThe results showed that operational carbon represented 90% of total life cycle carbon, whilst embodied carbon accounted for 10%. The sensitivity analysis revealed that 25% WWR contributes to a significant increase in operational carbon by 47.4%. Additionally, the efficient block wall with marble has a major embodiment of carbon greater than the base case by 10.7%.Research limitations/implicationsThis study is a contribution to the field of calculating the embodied and operational carbon emissions of a residential unit. Besides, it provides an examination of the impact of each envelope variable on both embodied and operational carbon. This study is limited by the impact of sixteen envelope variables on the embodied as well as operational carbon.Originality/valueThis study is the first attempt on investigating the effects of envelop variables on carbon footprint for residential buildings in Saudi Arabia.

Published: April 2021

PurposeEfflorescence formation is very common in cement-based materials. In the case of mortar, efflorescence is more studied when only Portland cement is used as a binder. However, the repair of historical heritage, as well as the construction system of some countries, usually uses mortars composed of hydrated lime and Portland cement. This study aims to determine the influence of the hydrated lime content on the incidence of efflorescence in mortars.Design/methodology/approachMortars with 0%, 50%, and 100% lime/cement ratio were studied, using three different methods to accelerate efflorescence formation. The surface area of mortars affected by efflorescence was quantified by analysis using image software. Also, analysis of mercury intrusion porosity test, flexural tensile, compressive strength, absorption of water by capillarity, porosity, XRD and TGA was performed.FindingsMore efflorescence in mortars with a higher amount of lime in their composition was observed. The results show that the increase in the lime content reduces the flexural tensile and the compressive strength and increased the absorption of water by capillarity and the porosity of the mortars. The material formed by the efflorescence was calcium carbonate, proven by microstructural tests.Originality/valueThe results of greater efflorescence formation in mortars with lime are important to alert users who apply this type of material. Some type of protection must be done more rigorously for lime-cement mortars, especially concerning contact with water, since efflorescence tends to be faster for this type of material.

Authors: Biasutti Michele , Concina Eleonora 
Published: April 2021

PurposeThe aim of this article is to examine the perspectives, experiences, roles and values of Italian primary school principals regarding the inclusion of migrant children.Design/methodology/approachThe method of the study is qualitative and consists of a semi-structured interview, which was carried out with 17 primary school principals and examined using content analysis.FindingsThe following six categories emerged: (1) school organisation and services, (2) projects and activities for inclusion, (3) teaching methods and strategies, (4) assessment, (5) networking and (6) challenges. The findings highlighted the complexity of the principals' role; they have to take on several tasks to foster a positive school experience for migrant students. A student-centred approach was considered relevant for intercultural education to promote inclusion and well-being. Curriculum activities were designed according to student needs.Research limitations/implicationsThe number of participants was limited, and they all worked in a small area of northeast Italy. Future research should examine the perspective of other school stakeholders such as teacher coordinators, the Commission for School Inclusion, teachers and tutors.Practical implicationsThe findings could be used as a framework for defining a model of the organisation of the school useful for discussing the relevance of the activities and for comparing schools in different contexts. The development of reflective practice to analyse the activities inside the schools could be considered.Social implicationsStakeholders could consider the findings before making decisions and developing policy actions countrywide.Originality/valueThe key factors included the awareness of the school principal role in managing the school and of the importance of connecting their school with the local community and external agencies.
Understanding the difference of values-based motivation of managerial workers in spa businesses in Thailand
Authors: Suwannarat Pornlapas 
Published: April 2021

PurposeThis study focuses on variations of the importance of core values through motivational domains of individuals by their cultural background. The effect of motivational domains on operational performance has also been investigated.Design/methodology/approachThe study used survey as the main data collection method to elicit data from managerial workers in spa businesses in four regions of Thailand. An unpublished database of spa businesses was provided to the study by the Thai Chamber of Commerce.FindingsSignificant variations of the importance of motivational domains of managerial workers can be found according to the subculture of each of the four regions of Thailand. In addition, the motivational domains have found their significant impact on worker operational performance.Research limitations/implicationsOne of the limitations of this study may be the distribution of samples because the study focuses on spa businesses, most of which in each region are located in big tourism provinces that may not be wholly representative of the characteristics of each region.Practical implicationsThis study will be of practical value for practitioners or managers of any firms since it is important to consider value variations when assessing the operational performance; workers, especially managerial workers, in each subculture may have different priorities in the motivational domains of their lives. This could affect their operational performance.Originality/valueThis is an original attempt to ascertain variations of core values through motivational domains by subculture. It fills a knowledge gap in under-researched area in the literature since so far a few studies have examined this issue in the ASEAN countries.

Published: April 2021

PurposeThe purpose of this paper is to determine the influence of mobile design features on consumers' mobile app stickiness intentions, as mediated by users' emotional response (pleasure, arousal and dominance).Design/methodology/approachUsing the stimulus–organism–response model, this study employed conditional process modelling to investigate the influence of three categories of mobile design features on users' stickiness intentions. The emotional responses of pleasure–arousal–dominance were investigated for their mediating effect. The participants included women aged 18–36.FindingsDesign features provided consumer-led interactions’ influence on emotional responses of pleasure, arousal and dominance. Mobile design features were not a significant predictor of stickiness intentions. Arousal was a significant mediator of mobile design features on stickiness intentions, whereas dominance had no mediating effects.Originality/valueThis paper extends the growing research on mobile applications by investigating design features using Magrath and McCormick's (2013) mobile marketing design framework. This paper also adds to the body of knowledge on stickiness within a mobile context.

PurposeThe stigmatisation of COVID-19 patients or suspected cases is a matter of grave concern across the world, including India. Today, COVID-19 patients or suspected cases are being stigmatised or labelled as “corona carrier” and “corona spreader” because of which they are facing social rejection, mental torture, abusive behaviour and violence in the society. The objectives of the present study are to examine the nature of stigma construction in Indian society during COVID-19 pandemic and to explore its outcome on the well-being of corona-affected people.Design/methodology/approachThe study uses content analysis method to explain the COVID-19 stigma. The data have been collected from various Indian newspapers and magazines. The researchers have analysed the content of the news items related to social stigma which were collected from March to September 2020.FindingsThe study finds that COVID-19 patients or suspected cases are insulted and discriminated rudely by their family members and neighbours, and in many cases, they are not allowed to enter the house or the neighbourhood. The study has also pointed out that many COVID-19 patients or suspected cases have committed suicide as a result of being stigmatisation. Finally, the study explores that this social stigma is spreading due to fake news, lack of awareness and fear of corona infection.Originality/valueThis is an original paper which is based on content analysis. The present study focuses on the social stigma in Indian society during COVID-19. Basically, the present study has applied the theory of Erving Goffman which is based on stigma to examine the nature and problem of social stigma during COVID-19. The study has found that there are three types of social stigma during the corona pandemic: self-made stigma, family-made stigma and society-made stigma.

Authors: Zia Muhammad Qamar , Naveed Muhammad , Bashir Muhammad Adnan , Iqbal Asif 
Published: April 2021

PurposeDrawing from social exchange theory, the purpose of this study is to investigate the influence of servant leadership on organizational citizenship behavior, turnover intentions and work performance through mediating role of job embeddedness.Design/methodology/approachThe data were gathered from 252 frontline employees of Pakistan's hotel industry in two-time lags with an interval of two months by using purposive sampling. PLS-SEM was applied for the analysis of data and hypothesis testing.FindingsThe study ascertained that job embeddedness is a potent mediator between the nexus of servant leadership and aforementioned work outcomes. The study results portray that servant leadership promotes job embeddedness, OCB, work performance and reduces turnover intentions.Research limitations/implicationsHotel management can use job embeddedness to boost servant leadership and reduce turnover intentions. In addition, management should also increase servant leadership by organizing training and workshops for their managers, which ultimately improves followers' organizational citizenship behavior and work performance.Practical implicationsHotel management can use job embeddedness to boost OCB, work performance and reduce turnover intentions. In addition, management should also increase servant leadership by organizing training and workshops for their managers, which ultimately improves followers' citizenship behavior and work performance.Originality/valueThere are numerous calls for research to ascertain as well as sparse literature available whether job embeddedness act as a mediator in the nexus of servant leadership and work outcomes or not. The current study fills these voids and contributes to the literature by empirically examining the mechanism of job embeddedness between servant leadership and the work outcomes.

Published: April 2021

PurposeThe purpose of this research is to identify the effect of transformational leadership and transactional leadership on task performance, as well as the mediating role of psychological empowerment.Design/methodology/approachA questionnaire survey was sent to 177 academic staff in a Public University in Malaysia. The data were analysed using SmartPLS 3.2.9.FindingsThe results show that only psychological empowerment is positively associated with task performance. Unexpectedly, transformational leadership and transactional leadership have no direct effect on task performance. However, there is an indirect positive relationship between leadership styles and task performance, whereby this relationship is mediated by psychological empowerment. Furthermore, both leadership styles positively influenced psychological empowerment.Research limitations/implicationsThis study was conducted among academicians from Public Universities in Malaysia using two types of leadership styles. Therefore, it is recommended for future study to include academician from private universities and also to consider more leadership styles dimensions. The finding of this study shows thatR2was 35.3% for psychological empowerment; according to Cohen (1988), this percentage indicates substantial predictive accuracy in explaining psychological empowerment. Nevertheless, it would be interesting to explore other factors.Practical implicationsEmpowered employees were highly responsible, put extra work effort and creative in doing their jobs, which tends to increase their performance at work. It is also found that psychological empowerment has the highest and largest effect, contributing to task performance (f2 = 0.389).Originality/valueThe inconsistencies of the previous studies' results provide evidence and opportunities for this study to review by including the mediating variable of leadership styles and task performance relationship.
