Authors: Chotipanich Sarich , Issarasak Sittiporn 
Published: April 2017

Purpose
This paper is a continuing exploration into facilities management (FM) strategy through the arrangement of its decision choices. The purpose of this paper is to identify the existence of FM operation strategy and to add empirical evidence to this subject to the field of FM and property management. Its main objectives are to gain insights into the arrangement of the FM strategic choices in operation and its relationship with business strategy.

Design/methodology/approach
The study investigated the configurations of operational approaches and activities that should reflect strategic decisions. The investigation was undertaken through a study of four reputed shopping malls located in Bangkok. The relevant data were collected through semi-structured interviews with the key FM persons of each case study, plus archival document searches, and observations of operational processes. Subsequently, the data were examined in a cross-case analysis to identify the key patterns of relationships between the FM operational arrangements and the business strategy of the mall.

Findings
This study found that the functional scheme of FM adopted in operations was deliberately related to the needs of business strategy and the operations of the given shopping mall. A range of strategic choices for FM operations was also found. Certain choices are shared among the case studies, while their arrangements varied according to the particular business strategy and context.

Research limitations/implications
The number of case studies was rather limited, while the results were predominantly involved with a single type of facility.

Originality/value
The study identified the pattern of strategic choices entailed in the FM operations in shopping malls. The findings add to the understanding on FM strategy by widening the perspectives about the strategic choices of FM operations and how they are connected with the business strategy and operation model of retail estate. It adds empirical evidence and case studies regarding FM operations and its strategic features.
Preparation of water-resistant adhesives from soy flour with less water-soluble components for wood bonding
Authors: Gui Chengsheng , Zhu J. , Liu Xq , Zhang Zhongtao 
Published: April 2017

Purpose
The purpose of this paper is to prepare a water-resistant adhesive (SA) from soy flour (SF) with less water-soluble components.

Design/methodology/approach
Defatted SF was suspended and stirred in water. Then, the pH of dispersion was adjusted to a predetermined value (i.e. 8, 9 or 10) by the addition of 2M sodium hydroxide (NaOH) solution. After stirring at a predetermined temperature (25°C, 35°C, 45°C) for different time (1 h, 2 h, 3 h), the 2M hydrochloric acid (HCl) solution was added in a dropwise manner into the dispersion until the pH value was adjusted to 4.5. Then, the dispersion was centrifuged at 6,000 rpm for 2 min. The obtained precipitate with less water-soluble components was used as an adhesive (SA) directly.

Findings
SA had a wet strength of 1.02 MPa when used for the fabrication of poplar plywood. Polyvinyl alcohol (PVA) solution was applied to improve the tack of SAs to wood surface and the viscosities of SAs were decreased from 10,200 cP to 4,100 cP at room temperature after the PVA addition. The soy proteins in SAs were not denatured to a large extent according to the differential scanning calorimetry and light microscopy. The remained multilevel structures of soy protein played a positive contribution to the water resistance of SAs, and the bond lines of cured SAs were much more stable than those of the cured SF and soy protein concentrate (SPC).

Research limitations/implications
The fluidity and solid content of soy adhesives is much lower than formaldehyde adhesives. Further investigations are needed to improve the fluidity of soy adhesives with high solid contents.

Originality/value
Novel water-resistant soy adhesives were provided.
Comparative study of rapid and conventional tooling for plastics injection molding
Authors: Mendible Gabriel Antonio , Rulander Jack A. , Johnston Stephen P. 
Published: April 2017

Purpose
This study aims to evaluate the performance of injection molding inserts produced via rapid and conventional manufacturing techniques considering the mechanical and thermal performance of the tools as well as the resulting molded part quality.

Design/methodology/approach
Three insert materials and manufacturing techniques were evaluated, jetted photopolymer (PolyJet) 3D printing using digital ABS, direct metal laser sintering (DMLS) using bronze and machining using stainless steel. Molding trials were performed, and the insert surface temperature, longevity and part properties were evaluated. Complementary information was acquired using computer simulation.

Findings
Similar behavior and part quality were observed in machined and DMLS inserts. The latter were used for 500 cycles without any signs of failure. PolyJet inserts had increased cycle time and slower rate of cooling which increased shrinkage and crystallinity in the molded parts. PolyJet inserts could be produced quickly at a lower cost than machined or DMLS inserts.

Research limitations/implications
Cooling within the insert was not studied; inserts were cooled indirectly by the mold plates behind them. Subsequent studies will incorporate cooling lines directly into the inserts.

Originality/value
Little research has been done to understand the thermal behavior of inserts manufactured via rapid tooling techniques. This study provides a direct comparison between rapid tooling techniques, which is supported by simulation results and analysis of the actual molding properties.

Authors: Soriano Heras Enrique , Blaya Haro Fernando , de Agustín del Burgo José María , Islán Marcos Manuel Enrique 
Published: April 2017

Purpose
The purpose of this paper is to present a solution for the levelling plate of fused deposition modelling (FDM) additive manufacturing (AM) systems. This automatic levelling system is presented as an evolution of actual systems, which uses a new ultrasound sensing system.

Design/methodology/approach
After obtaining a prototype, different tests were conducted for getting a system which solves the level plate problem and can be mounted in any FDM AM machine. Several benchmark models were obtained and compared with current equipment concepts for the validity of the product.

Findings
All tests were performed with high accuracy, enabling the production of geometries that could not have been achieved without this novel system.

Practical implications
This development will enable experienced users to set aside the problems of calibration and focus on the purpose of this type of machines, making prototypes.

Originality/value
A system architecture has been developed and integrated into an open hardware AM system, allowing real-time adjustment of the plate during each layer, thus eliminating the need of levelling the plate, allowing to achieve easier printing, and without increasing the cost significantly.
Selection of additive manufacturing processes
Authors: Wang Yuanbin , Blache Robert , Xu Xun 
Published: April 2017

Purpose
This study aims to review the existing methods for additive manufacturing (AM) process selection and evaluate their suitability for design for additive manufacturing (DfAM). AM has experienced a rapid development in recent years. New technologies, machines and service bureaus are being brought into the market at an exciting rate. While user’s choices are in abundance, finding the right choice can be a non-trivial task.

Design/methodology/approach
AM process selection methods are reviewed based on decision theory. The authors also examine how the user’s preferences and AM process performances are considered and approximated into mathematical models. The pros and cons and the limitations of these methods are discussed, and a new approach has been proposed to support the iterating process of DfAM.

Findings
All current studies follow a sequential decision process and focus on an “a priori” articulation of preferences approach. This kind of method has limitations for the user in the early design stage to implement the DfAM process. An “a posteriori” articulation of preferences approach is proposed to support DfAM and an iterative design process.

Originality/value
This paper reviews AM process selection methods in a new perspective. The users need to be aware of the underlying assumptions in these methods. The limitations of these methods for DfAM are discussed, and a new approach for AM process selection is proposed.
The challenge of building support for human resource programs
Authors: Maurer Rick 
Published: April 2017

Purpose
The purpose of this paper is to provide human resource (HR) leaders with a practical, straightforward approach to the challenge of building support (and reducing resistance). Building support for new programs is difficult in many organizations, and the cost of failed change is large. HR is not immune to these pitfalls. The primary reason that projects fail is resistance. Resistance itself is not the problem. But, how leaders look at and work with resistance is a significant problem.

Design/methodology/approach
This approach is based on some 20 years of practice working with leaders on ways to build support for change. The author has helped leaders apply this approach in HR departments, as well as many other departments within organizations. This approach has been applied in aerospace, healthcare, large city library systems and telecommunications, to name a few.

Findings
The key finding is not that this approach is so wonderful, but that the mindset of the leader(s) is the key. When a leader or a leadership team believes that people and their thoughts and feelings actually matter, and that the department is best-served by respecting the people who work with and for them, then building support for change has a good chance of succeeding. The approach described here works well with leaders who want to engage others with dignity and respect.

Practical implications
This paper is meant to be practical. In fact, it invites readers to consider a change they are considering as they read the paper. By the end of the paper, readers should begin to see ways to apply these ideas immediately. Many people apply these ideas without further education or consultant assistance.

Originality/value
Resistance remains a bad word in organizations. (Organization development is a notable exception to that generality.) Leaders often give lip service to engagement and take part in high-involvement activities but fail to follow through. The author attempts to make the work as easy to access as possible, while avoiding simplistic thinking, to give leaders low-risk ways to begin to increase their respect for people (and their resistance). Leaders who try out more respectful ways to engage people are likely to up the ante and experiment with deeper ways of making contact with others.
Dispersion beyond miles: configuration and performance in virtual teams
Authors: Prasad Ambika , DeRosa Darleen , Beyerlein Michael 
Published: April 2017

PurposeThe purpose of this paper is to understand different aspects of structural dispersion in virtual teams (VTs). The study measures five types of dispersion, their impact on VT performance and the moderating effect of electronic communication.Design/methodology/approachThe authors collected data from 44 globally distributed VTs representing 403 members. The authors used details of the members’ locations to measure five elements of dispersion for each team: spatial, time-zone, number of locations, extent of numerical balance across locations and extent of isolated members for a team. The authors used two items to assess effective electronic communication and measured team performance on four items from three sources – members, leaders and third-party stakeholders.FindingsUsing regression, the authors found that the number of sites, degree of team balance and isolation had a negative impact on team performance. Spatial and temporal dispersion did not impact performance. Effective electronic communication moderated the relationship of team performance with team balance and the number of sites.Research limitations/implicationsStudy presents novel findings on the role of team configuration in VTs. Limitations: the study provides pointers to the likelihood of a non-linear relationship between spatial distance and performance; however, the scope of the paper does not permit an examination of this model. Future research can study this relationship. Second, the study does not examine how team configuration impacts the team processes that discount performance. Finally, the study treats each index of dispersion as independent of the others. The analysis does not study the interplay between and among the indices.Practical implicationsThe findings provide clear indicators for managers and researchers of VTs on the issues associated with the location and configuration of the teams. Managers, while designing and managing dispersed members are now informed of the impact of the number of sites and the sub-group dynamics. The study underscores the importance of effective electronic communication in managing dispersion.Social implicationsThe study presents how faultiness based on location of VT sub-groups (as represented in the configuration of a team) can hamper performance. Literature suggests that this faultiness can also extend to social identities (based on gender, culture, etc.). The indicators provided by this study in this respect provide a topical focus for research because diverse dispersed teams are becoming more prevalent.Originality/valueThe study is the first empirical exploration of dispersion in VTs beyond the traditionally acknowledged dimensions of spatial distance and time-zones. It is a timely response to the recent trends in literature. Additionally, the study derives data from a unique data set of global VTs, thus making findings easily generalizable.
Emergence of team engagement under time pressure: role of team leader and team climate
Authors: Sharma Anshu , Bhatnagar Jyotsna 
Published: April 2017

PurposeThis paper aims to identify the determinants of team engagement emerging as a collective team-level phenomenon under time pressure context. The paper particularly explores how teams working under time pressure conditions use their social resources to develop into highly engaged teams.Design/methodology/approachThe paper develops a conceptual framework along with related propositions by integrating diverse literature from the field of team processes, leadership and engagement. The arguments are theoretically embedded into the job demands-resources (JD-R) model to explain the emergence of team engagement under time pressure conditions.FindingsThe suggested conceptual model based on the JD-R model reveal that teams working under time pressure conditions view it as a challenging job demand and, hence, use their social resources as a coping mechanism, thereby developing into highly engaged teams. However, the paper finds that for team engagement to emerge under time pressure, teams require two important determinants. These two main determinants are team leader engaging behaviors and team climate. Engaging team leader’s behaviors include four sub-components: emotional agility, use of humor, efficient delegation and quality of feedback. Team climate constitute three sub-components: open communication, fun at work and compassion within the team. Only teams which have a strong team climate and team leaders’ engaging behaviors tend to have high team engagement under time pressure contexts.Research limitations/implicationsThe paper offers implications for both HR and line managers in team-based organizations to promote factors that enhance team engagement, for teams to perform under time pressure situations.Originality/valueThe paper identifies determinants of team engagement under time pressure context and further adds to the understanding of team processes by theoretically exploring how time pressure as a job demand can be channeled in a positive manner for promoting team engagement by using teams’ social resources: team leader’s engaging behaviors and team climate.
The impact of within-team variance on transactive memory system development and team performance
Authors: King Kylie Goodell 
Published: April 2017

Purpose
The purpose of this paper is to describe the dispersion models, where within-team variance is the outcome of interest, and propose the application of these models to the measurement of the transactive memory system (TMS). As teams become increasingly prominent in educational contexts and within organizations, it is important to evaluate how various measures of individual and team attributes relate to team performance. One measure that has been evaluated by a number of previous empirical studies is TMSs.

Design/methodology/approach
In past studies of TMS and in most teams research, team-level data are collected and correlated with performance, or individual-level data are collected, aggregated to the team-level data and then correlated with performance. While this is appropriate in situations where data are isomorphic or similar across levels of measurement, there are often important differences among within-team responses that lead to a discrepancy between the sum of individual attributes and a team-level measure.

Findings
Preliminary results demonstrate that within-team variance in reported levels of TMS has an inverse relationship with team performance.

Research limitations/implications
Future research should further evaluate the ability for dispersion models of TMS to predict team performance, especially in organizational settings with professional rather than student teams.

Originality/value
This paper provides a new approach to measuring TMS and relating TMS to team performance.
Estimating melanin location in the pigmented skin lesions by hue–saturation–lightness color space values of dermoscopic images
Authors: Sakai Hiroshi , Ando Yoshimi , Ikinaga Kuniko , Tanaka Masaru 
Published: April 2017

AbstractThe depth of melanin in the skin can be estimated roughly by observation of the color exhibited on dermoscopy. Currently, there are no objective methods to estimate it. The aim of the present study was to clarify the relationship between the depth of melanin in the skin and the color variation exhibited, and to objectively estimate the 3‐D location of melanin in the pigmented skin lesions from dermoscopic images. Representative colors in dermoscopic images of acral compound nevus, Spitz nevus and blue nevus were evaluated by the subjectively perceived color on dermoscopy and objective values in hue–saturation–lightness color space values. Brown colors due to small quantities of superficial melanin in the skin had high saturation and low lightness values, whereas black colors due to large quantities of superficial melanin had low saturation and low lightness values. On the other hand, colors due to melanin in the dermis were perceived as blue–gray on dermoscopy, but extracted colors showed gray–brown hue and intermediate saturation and high lightness values. In all cases, extracted representative colors of pigmented skin lesions had similar hue values within the red–orange range. Objective estimation of the 3‐D location of melanin in the pigmented skin lesions is possible by the saturation and lightness values of the colors extracted from dermoscopic images. Subjectively perceived colors of melanin, especially in the dermis, can be modified by the surrounding environment effect and blue color perception.

AbstractRosacea is a chronic dermatological disease. Helicobacter pylori has been discussed as one of its causative factors. In this clinical trial study, we attempted to evaluate the effect of H. pylori standard eradication protocol on the rosacea clinical course. In this single‐arm clinical trial, patients ascertained to have H. pylori infection based on serological studies were assessed to examine existence of rosacea. Patients with concurrent rosacea and H. pylori infection were included in the study and underwent standard H. pylori eradication therapy. Rosacea was evaluated using the Duluth rosacea grading score at the beginning, 2 months later and at the end of the trial (day 180). Of 872 patients positive for H. pylori, 167 patients (19.15%) manifested the clinical features of rosacea. The patients with concurrent rosacea were younger (P < 0.001) and with a female sex predominance (P = 0.03) when compared with rosacea‐free patients. Of 167 patients, 150 received H. pylori eradication therapy, demonstrating a 92% (138/150) cure rate. The rosacea Duluth score grading on day 0, 60 and 180 among 138 patients significantly decreased in most of the criteria except for telangiectasias (P = 0.712), phymatous changes (P = 0.535) and the existence of peripheral involvement (P = 0.431). The present study concluded that H. pylori eradication leads to improvement of rosacea.

SummarySoil carbon (C) stabilisation is known to depend in part on its distribution in structural aggregates, and upon soil microbial activity within the aggregates. However, the mechanisms and relative contributions of different microbial groups to C turnover in different aggregates under various management practices remain unclear. The aim of this study was to determine the role of soil aggregation and their associated microbial communities in driving the responses of soil organic matter (SOM) to multiple management practices. Our results demonstrate that higher amounts of C inputs coupled with greater soil aggregation in residue retention management practices has positive effects on soil C content. Our results provide evidence that different aggregate size classes support distinct microbial habitats which supports the colonisation of different microbial communities. Most importantly our results indicate that the effects of management practices on soil C is modulated by soil aggregate sizes and their associated microbial community and are more pronounced in macro‐aggregate compared with micro‐aggregate sizes. Based on our findings we recommend that differential response of management practices and microbial control on the C turnover in macro‐aggregates and micro‐aggregate should be explicitly considered when accounting for management impacts on soil C turnover.
