Sentiment classification of Chinese cosmetic reviews based on integration of collocations and concepts
Authors: Hung Chihli , Cao You-Xin 
Published: December 2019

Purpose
This paper aims to propose a novel approach which integrates collocations and domain concepts for Chinese cosmetic word of mouth (WOM) sentiment classification. Most sentiment analysis works by collecting sentiment scores from each unigram or bigram. However, not every unigram or bigram in a WOM document contains sentiments. Chinese collocations consist of the main sentiments of WOM. This paper reduces the complexity of the document dimensionality and makes an improvement for sentiment classification.

Design/methodology/approach
This paper builds two contextual lexicons for feature words and sentiment words, respectively. Based on these contextual lexicons, this paper uses the techniques of associated rules and mutual information to build possible Chinese collocation sets. This paper applies preference vector modelling as the vector representation approach to catch the relationship between Chinese collocations and their associated concepts.

Findings
This paper compares the proposed preference vector models with benchmarks, using three classification techniques (i.e. support vector machine, J48 decision tree and multilayer perceptron). According to the experimental results, the proposed models outperform all benchmarks evaluated by the criterion of accuracy.

Originality/value
This paper focuses on Chinese collocations and proposes a novel research approach for sentiment classification. The Chinese collocations used in this paper are adaptable to the content and domains. Finally, this paper integrates collocations with the preference vector modelling approach, which not only achieves a better sentiment classification performance for Chinese WOM documents but also avoids the curse of dimensionality.
BIM for FM
Authors: Matarneh Sandra T. , Danso-Amoako Mark , Al-Bizri Salam , Gaterell Mark , Matarneh Rana T. 
Published: December 2019

Purpose
This paper aims to identify a generic set of information requirements for facilities management (FM) systems, which should be included in BIM as-built models for efficient information exchange between BIM and FM systems, and to propose a process to identify, verify and collect the required information for use in FM systems during the project’s lifecycle.

Design/methodology/approach
Both qualitative and quantitative approaches were applied at different stages of the study’s sequential design. The collection and analysis of qualitative data was based on an extensive literature review of similar studies, standards, best practices and case study documentation. This was followed by a questionnaire survey of 191 FM practitioners in the UK. This formed the background of the third stage, which was the development of the information management process to streamline information exchange between building information models and FM systems.

Findings
The study identifies a generic list of information requirements of building information models to support FM systems. In addition, the study presents an information management process that generates a specific database for FM systems using an open data format.

Originality/value
The existing literature focuses on specific building types (educational buildings) or specific information requirements related to particular systems (mechanical systems). The existing standards, guidelines and best practices focus on the information requirements to support the operations and maintenance (O&M) phase in general. This study is different from previous studies because it develops a set of specific information requirements for building information models to support FM systems. FM organisations and owners can use the proposed list of information requirements as a base to generate specific data output for their FM systems’ input, to decrease the redundant activity of manual data entry and focus their efforts on key activities.
Restructuring degree roadmaps to improve timely graduation in higher education
Authors: Su Xuemei , Chen Ming , Yur-Austin Jasmine , Liu Ying 
Published: December 2019

Purpose
Faced with declining government funding support and rising student loan debt, recently timely graduation in higher education has become a focal point of discussion at many institutions, particularly public universities. Timely graduation requires a student to successfully enroll in and complete a set of required and elective courses, the relationship of which is bound by the courses’ prerequisite requirements. However, due to the fact that class capacity is oftentimes limited and wrongly timed, many students find it challenging to stay on track. A well-structured degree roadmap that takes all factors into consideration and specifies the right courses to take by semester will better guide students’ course selection and thus increase their chance of earning their degrees within the four-year time window. Additionally, it will also allow administrators to do better capacity planning, and hence increase course accessibility to students. The paper aims to discuss these issues.

Design/methodology/approach
In this research, some operational techniques such as line balancing and simulation are applied to restructure and improve degree roadmaps, and assess the resulting outcomes. Some innovative methods are proposed to improve the processes on which students proceed to degree.

Findings
The results based on historical data that contains millions of student records spanning over eight-year time window demonstrate that the improved degree roadmaps can substantially increase students’ chance of completing the degree in a four-year time window. The research findings provide university administrators with cost-effective solutions.

Originality/value
This research breaks a new ground in literature due to its unique approach and focus. To the best of the authors’ knowledge, this research is one of the first attempts to systematically study the impact of degree roadmap on timely graduation. This research focuses on finding solutions that are within the institution’s control, hence the proposed solutions are implementable and will provide university administrators with new tools and perspectives to enhance student success.
How does negative experience sharing influence happiness in online brand community? A dual-path model
Authors: Zhou Zhimin , Zhan Ge , Zhou Nan 
Published: December 2019

PurposeConsumers share negative brand experience in many occasions to vent their emotion and seek support. The purpose of this paper is to investigate the impact of negative sharing on members’ happiness in online brand communities by drawing from two opposing constructs: social support and social exclusion.Design/methodology/approachBoth survey and experiment methods were employed to test the conceptual model. Online survey data were collected from 1,015 mobile internet users.FindingsThe findings reveal that negative sharing may enhance a sharer’s happiness through online social support particularly for novice community members. The findings also indicate greater online social exclusion for experienced members than for novice members. These findings cast doubt on the widely held assumption that increased engagement in a community will always produces positive outcomes. The moderating effect of membership duration is confirmed with an experiment of MI’s brand community members.Research limitations/implicationsThe study of happiness in online brand community sheds new light on consumer–brand and user–community relationships.Originality/valueWhile most previous studies on negative sharing only explored the negative side of consequences, the authors contribute to this line of research by introducing both positive (social support) and negative (social exclusion) outcomes of negative reviews. The model also explains the conditions under which negative reviews enhance social support and social exclusion.
Demolition and deconstruction legacies: Toronto’s Honest Ed’s and Mirvish Village
Authors: Creba Alison 
Published: December 2019

Purpose
Building on the thematic intersection of architectural waste and conservation, the purpose of this paper is to look at the demolition and deconstruction of Honest Ed’s and Mirvish Village – an iconic site in downtown Toronto. In doing so, it examines contradictory site values and tensions inherent in sustainable heritage practices.

Design/methodology/approach
This article uses a “follow-the-thing” methodology – an approach developed by the cultural geographer Nicky Gregson (Gregson et al., 2009) – to demonstrate how engaging with processes of building demolition and deconstruction can begin to reveal the site’s multiple legacies.

Findings
Recognizing that materials are not lost, but instead move through and are determined by various physical, spatial and cultural conditions, this piece demonstrates how an attention to the choreography of demolition and deconstruction may deepen our understanding of notions of ownership, responsibility and stewardship.

Research limitations/implications
Exposing material trajectories and various actors in the chain, this work challenges the save/discard binary which underpins conventional heritage practices and provides insight into new ways of considering the significance of demolition/deconstruction sites as well as broader social and environmental landscapes implicated in its reconfiguration.

Originality/value
Whereas heritage value is often defined in contrast with perceptions of loss, this piece suggests that engagement with processes of demolition and deconstruction constitutes a form of conservation that simultaneously acknowledges the difficult heritage of these procedures, while also commemorating the site’s ongoing transformation.
Learning the Ashby Box: an experiment in second order cybernetic modeling
Authors: Cretu Andrei 
Published: December 2019

Purpose
W. Ross Ashby’s elementary non-trivial machine, known in the cybernetic literature as the “Ashby Box,” has been described as the prototypical example of a black box system. As far as it can be ascertained from Ashby’s journal, the intended purpose of this device may have been to exemplify the environment where an “artificial brain” may operate. This paper describes the construction of an elementary observer/controller for the class of systems exemplified by the Ashby Box – variable structure black box systems with parallel input.

Design/methodology/approach
Starting from a formalization of the second-order assumptions implicit in the design of the Ashby Box, the observer/controller system is synthesized from the ground up, in a strictly system-theoretic setting, without recourse to disciplinary metaphors or current theories of learning and cognition, based mainly on guidance from Heinz von Foerster’s theory of self-organizing systems and W. Ross Ashby’s own insights into adaptive systems.

Findings
Achieving and maintaining control of the Ashby Box requires a non-trivial observer system able to use the results of its interactions with the non-trivial machine to autonomously construct, deconstruct and reconstruct its own function. The algorithm and the dynamical model of the Ashby Box observer developed in this paper define the basic specifications of a general purpose, unsupervised learning architecture able to accomplish this task.

Originality/value
The problem exemplified by the Ashby Box is fundamental and goes to the roots of cybernetic theory; second-order cybernetics offers an adequate foundation for the mathematical modeling of this problem.

Published: December 2019

PurposeThe purpose of this paper is to explore the adoption of lean practices by manufacturing companies in regions of low economic and technological development and to compare findings with previous studies from more developed regions highlighting important contextual differences. The paper uses the contingency theory to explore how contextual variables and scarce resources influence the adoption of lean practices.Design/methodology/approachA survey of 233 manufacturing firms was conducted in the State of Pará in the Amazon Region of Brazil.FindingsThe results demonstrate that six internal lean practices (single minute exchange of dies, human resource management, continuous flow, total productive maintenance, pull and statistical process control) and two external lean practices (supplier feedback and customer involvement) are implemented. However, the two external lean practices of just-in-time delivery by suppliers and supplier development were not implemented. Furthermore, from the 36 operating items comprised in eight lean practices that are being used, 13 were not implemented. As such, compared to developed regions, there is evidence for a more fragmented implementation in less developed regions. The results reveal empirical evidence explained by the contingency perspective, such as national, geographical, strategic context and culture.Originality/valueThere is broad evidence on lean implementation in developed and developing countries in the literature. However, little is known about lean implementation in poorer regions of developing counties. This is one of the first studies mapping lean implementation in a region with low economic and technological development. This has important implications for research and practice, especially to cross-country/cultural research on operation management.
The spillover effect of greenwashing behaviours: an experimental approach
Authors: Wang Hong , Ma Baolong , Bai Rubing 
Published: December 2019

Purpose
The purpose of this paper is to examine the impact of greenwashing behaviour of one brand on purchase intention of green products from other brands. Further, this study tests the mediating role of greenwashing perception of the entire industry and the moderating role of brand attitudes towards other brands in the industry for the above-mentioned relationship.

Design/methodology/approach
A sample of 377 participants was utilised in three studies. The study analysed the data using SPSS 18.0 to test the research hypotheses.

Findings
The study suggests that greenwashing behaviour of one brand negatively affects consumers’ purchase intention of the green products from other brands in the industry. It is also indicated that the greenwashing perception of the entire industry partially mediates the relationship between greenwashing behaviour of a brand and purchase intention of green products from other brands. In addition, the study shows that the relationship between greenwashing perception of the entire industry and purchase intention of the green products from other brands is negatively moderated by brand attitudes towards other brands in the industry.

Practical implications
This study provides useful insights for the managers that firms can learn the way to alleviate greenwashing spillover effect through the brand attitudes to enhance green purchasing behaviour.

Originality/value
The study is perhaps the first one to study the existence of the spillover effect of brands’greenwashing behaviour. The study also reveals the influencing mechanism of greenwashing spillover effect of a brand.
Climate risk perception and media framing
Authors: Brito Renata Peregrino de , Miguel Priscila Laczynski de Souza , Pereira Susana Carla Farias 
Published: December 2019

Purpose
This study aims to analyze the media coverage of the impact of extreme weather events (EWE) and related risk management activities in Brazil.

Design/methodology/approach
Using a documentary analysis, the authors examined the media coverage of droughts and floods from 2003 to 2013 with concomitant official reports.

Findings
The results indicate that although media coverage conveys the direct impact of floods and droughts on society, it underemphasizes the importance of risk management activities. Moreover, the private sector rarely engages in risk management and mitigation activities, despite the documented supply chain disruptions.

Research limitations/implications
This study focuses solely on media coverage as provided by wide-circulation newspaper in Brazil and would benefit by being extended to all media platforms.

Practical implications
The results highlight the need for private sector involvement in risk management activities to facilitate the adaptation to climate change.

Social implications
The study reveals the deficiency of existing reports and lack of awareness regarding EWE.

Originality/value
The study contributes by focusing on climate awareness and how society can adapt to climate change, as well as how businesses can improve supply chain operations to facilitate smoother risk management.
Chromium effects on the microstructural, mechanical and thermal properties of a rapidly solidified eutectic Sn-Ag alloy
Authors: Abbas Sanaa Razzaq , Gumaan Mohammed S. , Shalaby Rizk Mostafa 
Published: December 2019

Purpose
This study aims to investigate the chromium (Cr) effects on the microstructural, mechanical and thermal properties of melt-spun Sn-3.5Ag alloy.

Design/methodology/approach
Ternary melt-spun Sn-Ag-Cr alloys were investigated using X-ray diffractions, scanning electron microscope, dynamic resonance technique, instron machine, Vickers hardness tester and differential scanning calorimetry.

Findings
The results revealed that the Ag3Sn intermetallic compound (IMC) and ß-Sn have been refined because of the hard inclusions’ (Cr atoms) effects, causing lattice distortion increasing these alloys. The tensile results of Sn96.4-Ag3.5-Cr0.1 alloy showed an improvement in Young’s modulus more than 100 per cent (42.16 GPa), ultimate tensile strength (UTS) by 9.4 per cent (23.9 MPa), compared with the eutectic Sn-Ag alloy due to the high concentration of Ag3Sn and their uniform distribution. Shortage in the internal friction (Q−1) of about 54 per cent (45.1) and increase in Vickers hardness of about 7.4 per cent (142.1 MPa) were also noted. Hexagonal Ag3Sn formation led to low toughness values compared to the eutectic Sn-Ag alloy, which may have resulted from the mismatching among hexagonal Ag3Sn phase with orthorhombic Ag3Sn and ß-Sn phases. Mechanically, the values of Young’s modulus have been increased, with increasing chromium content, whereas the UTS and toughness values have been decreased. The opposite of this trend appeared in Sn95.8-Ag3.5-Cr0.7 alloy, which may have been due to high lattice distortion (ƹ = 16.5 × 10−4) compared to the other alloys. Increase in the melting temperature Tm, ΔH, Cp and ΔT was because of Ag3Sn IMC formation. The low toughness of Sn96-Ag3.5-Cr0.5 and Sn95.8-Ag3.5-Cr0.7 (109.56 J/m3 and 35.66 J/m3), relatively high melting temperature Tm (223.22°C and 222.65°C) and low thermal conductivity and thermal diffusivity (32.651 w.m−1.k−1 and 0.314 m2/s) make them undesirable in the soldering process. The high UTS, high E, high thermal conductivity and diffusivity, low creep rate and low electrical resistivity, which have occurred with “0.1 Wt.%” of Cr, make this alloy desirable and reliable for soldering applications and electronic assembly.

Originality/value
This study provides chromium effects on the structure of the eutectic Sn-Ag rapidly solidified by melt-spinning technique. In this paper, the authors compared the elastic modulus of the melt-spun compositions, which have been resulted from the Static method with that have been resulted from the Dynamic method. This paper presents new improvements in mechanical and thermal performance.
Searching for ‘pockets of effectiveness’ in weak governance states: Preliminary examination of the securities and exchange commission of Myanmar
Authors: Soe Phone Pyae , Lowatcharin Grichawat , Crumpton Charles David , Draper John 
Published: December 2019

AbstractAfter decades of military rule, internal conflict, and international isolation, Myanmar has embarked on a course of institution building. In light of Myanmar's low rating on the World Bank's Worldwide Governance Indicators (World Bank Group), the nation faces an enormous challenge in developing public institutions that meet its needs and expectations. This challenge includes development of institutional capacity that will allow Myanmar to participate in international economic affairs. A step in this direction involves the creation of a securities exchange market mechanism. The current study considers the establishment of the Securities and Exchange Commission of Myanmar (SECM) to support securities regulation. It applies a novel organization level of analysis strategy that considers SECM as a ‘pocket of effectiveness’ (POE) in the context of a low‐performing public institutional setting in terms of the good governance criteria of responsiveness, accountability, and transparency (RAT). While the study finds evidence of progress in building Myanmar's securities regulation, it also finds limits in RAT development that challenges the SECM's potential designation as a ‘POE’. Based on feedback from proximate stakeholders in the daily work of the SECM, recommendations are offered for revised policies and practices in order to resolve them.
Diversity of bacteria associated with Hormaphidinae aphids (Hemiptera: Aphididae)
Authors: Xu Ting‐Ting , Chen Jing , Jiang Li‐Yun , Qiao Ge‐Xia 
Published: December 2019

AbstractBacteria are ubiquitous inhabitants of animals. Hormaphidinae is a particular aphid group exhibiting very diverse life history traits. However, the microbiota in this group is poorly known. In the present study, using high‐throughput sequencing of bacterial 16S ribosomal RNA gene amplicons, we surveyed the bacterial flora in hormaphidine aphids and explored whether the aphid tribe, host plant and geographical distribution are associated with the distribution of secondary symbionts. The most dominant bacteria detected in hormaphidine species are heritable symbionts. As expected, the primary endosymbiont Buchnera aphidicola is the most abundant symbiont across all species and has cospeciated with its host aphids. Six secondary symbionts were detected in Hormaphidinae. Arsenophonus is widespread in Hormaphidinae species, suggesting the possibility of ancient acquisition of this symbiont. Ordination analyses and statistical tests show that the symbiont composition does not seem to relate to any of the aphid tribes, host plants or geographical distributions, which indicate that horizontal transfers might occur for these symbionts in Hormaphidinae. Correlation analysis exhibits negative interference between Buchnera and coexisting secondary symbionts, while the interactions between different secondary symbionts are complicated. These findings display a comprehensive picture of the microbiota in Hormaphidinae and may be helpful in understanding the symbiont diversity within a group of aphids.
