Variable selection framework for allocating products to recommended replenishment models in VMI applications
Authors: Anzanello Michel , Mazzillo Cézar , Tortorella Guilherme , Marodin Giuliano 
Published: March 2017

Purpose
The purpose of this paper is to propose a multivariate-based method to classify products in replenishment categories based on principal component analysis (PCA) along with two classification algorithms, k-nearest neighbor (KNN) and linear discriminant analysis (LDA).

Design/methodology/approach
In the propositions, PCA is applied to data describing products’ features and demand behavior, and a variable importance index (VII) is derived based on PCA parameters. Next, products are allocated to inventory replenishment models applying the KNNs to all original variables; the classification accuracy is then assessed. The variable with the smallest VII is removed and a new classification is carried out; this iterative procedure is performed until a single variable is left. The subset yielding the maximum classification accuracy is recommended for future classification. The aforementioned procedure is repeated replacing the KNN by the LDA.

Findings
When applied to real data from a consulting company, the KNN classification technique led to higher performance levels than LDA, yielding 89.4 percent average accuracy and retaining about 80 percent of the original variables. On the other hand, LDA reached 87.1 percent average accuracy and retained 95 percent of the variables. Based on such results, the authors’ findings suggest that 14 out of the 24 variables are crucial in determining an inventory replenishment model for a product in a specific location replacement. Several of the retained variables were typically used in reorder point estimation or associated to market profile in specific locals.

Originality/value
The idea of this paper is to remove irrelevant and noisy market metrics that jeopardize the correct allocation of products to the most appropriate replenishment model.
Modeling reconfigurability in supply chains using total interpretive structural modeling
Authors: Biswas Pallab 
Published: March 2017

Purpose
The purpose of this paper is to identify, analyze, and categorize the major enablers of reconfigurability that can facilitate structural changes within a supply chain in a global scenario. The paper also addresses five reconfigurability dimensions in the perspective of supply chains and the major enablers to attain them. The paper further aims to understand the mutual interactions among these enablers through the identification of hierarchical relationships among them.

Design/methodology/approach
A framework that holistically considers all the major enablers of reconfigurability has been developed. The hierarchical interrelationships between major enablers have been presented and interpreted using a novel qualitative modeling technique, i.e., total interpretive structural modeling (TISM), which is an extension of ISM. SPSS 22.0 is employed to carry out a one-tailed one-sample t-test further to test the hypotheses for validating the results of TISM. Impact matrix cross-reference multiplication applied to a classification (MICMAC) analysis has been employed to identify the driving and dependence powers of these reconfigurability enablers.

Findings
In this paper, 15 enablers for reconfigurability paradigm have been identified through literature review and expert opinions. The authors established interrelationships and interdependencies among these enablers and categorized them as enablers of each dimension. New product development and customer satisfaction come at the highest level of priority. The levels of these enablers were obtained using TISM. The authors compared the results with the clusters derived from MICMAC analysis, and the results are found to be well within the acceptable range.

Research limitations/implications
The study has implications for both practitioners and academia. The work provides a comprehensive list of enablers that are relevant to reconfigure supply chains in today’s volatile global market. This research will also help decision makers to strategically focus on the top-level enablers and their concerned dimensions. The research is based on an automobile company case study and can be extended to products with volatile and changing demands.

Originality/value
The proposed model for reconfigurability enablers using TISM is a new effort altogether in the area of supply chain management. The novelty of this research lies in its identification of specific enablers to reconfigure a supply chain through different dimensions.
Delivering the message
Authors: Moorefield-Lang Heather Michele 
Published: March 2017

Purpose
The purpose of this paper is to describe the use of podcasts, online radio broadcasts, YouTube channels, and other technology medium to deliver information and professional development to peers in the field and professionals in librarianship.

Design/methodology/approach
This paper explores five case studies of librarians and library professionals who have created online programs specifically geared to the field using technologies such as podcasting, YouTube channels, Twitter Chats, and Google Hangouts. The case studies include librarians in the public, academic, and school settings as well as one professional from The American Library Association. Interviews via Google Hangouts took place to gather information for each narrative. NVivo 10 qualitative data analysis software was used to pull out themes and commonalities among narratives. Some examples include, intended audience, program focus, platform topics, technology, and challenges.

Findings
Face-to-face delivery of information and professional development can be difficult with librarians and professionals located across the USA and the world. These five interviewees share new opportunities and examples in the delivery of training and information in the field of librarianship without ever needing to leave an office or desk.

Originality/value
Podcasting in librarianship is a topic of modest popularity but it is typically used with students and at the academic library level where the topics of podcasts and libraries are addressed. The topics of podcasts, online radio broadcasts, and other technologies in librarian peer-to-peer instruction and professional development are uncharted territory in the field of scholarly research. This piece opens research to multiple opportunities in both practice and scholarship in how technology can aid in professional development and information delivery to peers and practitioners in the field.
Promoting information literacy: perspectives from UK universities
Authors: Ellis Claire , Johnson Frances , Rowley Jennifer 
Published: March 2017

Purpose
Academic libraries have sought to become the leaders in the provision of information literacy (IL). The purpose of this paper is to identify to what extent IL is being promoted through institutional websites.

Design/methodology/approach
Data were collected from all UK university websites (n=133) in early 2015 to identify the promotion of IL. Content analysis was used for the five categories: IL in the mission statement, visions or strategic plan; IL model or framework; IL policy; IL assessment; and, IL training. Data collection was limited to information in the public domain which could be accessed from individual websites, which were searched and browsed systematically.

Findings
In total, 85.7 per cent of universities promote IL to some extent on their websites in at least one of the five categories, however the degree of the information provided varied extensively. Less than 6 per cent of universities promote IL at institutional level. Only 17.3 per cent refer to a model or framework, 15.8 per cent show their IL policy and 9 per cent provide information on their assessment of students’ IL skills. Information on IL training is offered on 84.2 per cent of websites, the most common method being online tutorials, although 52.6 per cent only offer training for one or two aspects of IL, primarily information seeking and citing and referencing.

Originality/value
This paper provides up-to-date data concerning how universities in the UK promote IL in the public domain via their websites. It should be of interest to academic librarians who are responsible for IL provision.
Using linked open data to enhance the discoverability, functionality and impact of Emblematica Online
Authors: Cole Timothy W. , Han Myung-Ja K. , Janina Sarol Maria , Biel Monika , Maus David 
Published: March 2017

Purpose
Early Modern emblem books are primary sources for scholars studying the European Renaissance. Linked Open Data (LOD) is an approach for organizing and modeling information in a data-centric manner compatible with the emerging Semantic Web. The purpose of this paper is to examine ways in which LOD methods can be applied to facilitate emblem resource discovery, better reveal the structure and connectedness of digitized emblem resources, and enhance scholar interactions with digitized emblem resources.

Design/methodology/approach
This research encompasses an analysis of the existing XML-based Spine (emblem-specific) metadata schema; the design of a new, domain-specific, Resource Description Framework compatible ontology; the mapping and transformation of metadata from Spine to both the new ontology and (separately) to the pre-existing Schema.org ontology; and the (experimental) modification of the Emblematica Online portal as a proof of concept to illustrate enhancements supported by LOD.

Findings
LOD is viable as an approach for facilitating discovery and enhancing the value to scholars of digitized emblem books; however, metadata must first be enriched with additional uniform resource identifiers and the workflow upgrades required to normalize and transform existing emblem metadata are substantial and still to be fully worked out.

Practical implications
The research described demonstrates the feasibility of transforming existing, special collections metadata to LOD. Although considerable work and further study will be required, preliminary findings suggest potential benefits of LOD for both users and libraries.

Originality/value
This research is unique in the context of emblem studies and adds to the emerging body of work examining the application of LOD best practices to library special collections.
Novel exploration of 3D printed wrist arthroplasty to solve the severe and complicated bone defect of wrist
Authors: Han Qing , Qin Yanguo , Zou Yun , Wang Chenyu , Bai Haotian , Yu Tao , Huang Lanfeng , Wang Jincheng 
Published: March 2017

Purpose
Although proximal row carpectomy, wrist arthrodesis and even total wrist arthroplasty were developed to treat wrist disease using bone and cartilage of the wrist, severe and complicated bone defects caused by ferocious trauma and bone tumors remain a stubborn problem for surgeons. Development and application of the three-dimensional (3D) printing technology may provide possible solutions.

Design/methodology/approach
Computed tomography (CT) data of three cases with severe bone defects caused by either trauma or bone tumor were collected and converted into three-dimensional models. Prostheses were designed individually according to the residual anatomical structure of the wrist based on the models. Both the models and prostheses were produced using 3D printing technology. A preoperative design was prepared according to the models and prostheses. Then arthroplasty was performed after preoperative simulation with printed models and prostheses.

Findings
The diameter of the stem and radial medullary cavity, the direction and location of the prosthesis, and other components were checked during the preoperative design and simulation process phases. The three cases with 3D printed wrist all regained reconstruction of normal anatomy and part of the function after surgery. The average increasing Cooney score rate of Cases 2 and 3 was 133.34 ± 23.57 per cent, and that of Case 1 reached 85 per cent. The average declining rate of the Gartland and Werley Score in Cases 2 and 3 was 65.21 ± 18.89 per cent, and that of Case 1 dropped to 5 per cent in the last follow-up. The scores indicated that patients experienced pain relief and function regain. In addition, the degree of patient satisfaction improved.

Originality/value
3D printed wrist arthroplasty may provide an effective method for severe and complicated cases without sacrificing other bones. Personal customization can offer better anatomy and function than arthrodesis or other traditional surgical techniques.
System and process development for coaxial extrusion in fused deposition modelling
Authors: Taylor Adam C. , Beirne Stephen , Alici Gursel , Wallace Gordon G. 
Published: March 2017

Purpose
This paper aims to design and test a system capable of coaxial fused deposition modelling (FDM) and assess the coaxial fibres produced for their coaxial concentricity. The goal is to achieve concentricity values below the literature standard of 15 per cent.

Design/methodology/approach
This research discusses the design of the coaxial nozzle internal geometry and validates the modelling process by using computational fluid dynamics to assess its flow profile. Sequentially, this paper discusses the abilities of current additive manufacturing (AM) technology in the production of the coaxial nozzle.

Findings
The methodology followed has produced coaxial fibres with concentricity values as low as 2.89 per cent and also identifies a clear speed suitable for coaxial printing using polylactic acid (PLA) as the internal and external materials.

Research limitations/implications
The concentricity of the printed fibres is heavily influenced by the feed rate for the thermoplastic feedstock. This in turn alters the viscosity of the material to be printed, implying that a relationship exists between feed rate and print temperature, which can be further optimised to potentially obtain higher concentricity values.

Practical implications
This paper adds reliability and repeatability to the production of coaxially printed structures, the likes of which has numerous potential applications for biological printing.

Originality/value
The outcomes of this study will provide an AM platform to alter the paradigm of biofabrication by introducing a new level of versatility to the construction of biofabricated structures.
Tensile strength of partially filled FFF printed parts: meta modelling
Authors: Mahmood Shahrain , Qureshi A.J. , Goh Kheng Lim , Talamona Didier 
Published: March 2017

Purpose
This paper aims to investigate the tensile strength of partially filled fused filament fabrication (FFF) printed parts with respect of cross-sectional geometry of partially filled test pieces. It was reported in the authors’ earlier work that the ultimate tensile strength (UTS) is inversely proportional to the cross-sectional area of a specimen, whereas the number of shells and infill density are directly proportional to the UTS with all other parameters being held constant. Here, the authors present an in-depth evaluation of the phenomenon and a parametric model that can provide useful estimates of the UTS of the printed part by accounting for the dimensions of the solid floor/roof layers, shells and infills.

Design/methodology/approach
It was found that partially filled FFF printed parts consist of hollow sections. Because of these voids, the conventional method of determining the UTS via the gross cross-sectional area given by A = b × h, where b and h are the width and thickness of the printed part, respectively, cannot be used. A mathematical model of a more accurate representation of the cross-sectional area of a partially filled part was formulated. Additionally, the model was extended to predict the dimensions as well as the lateral distortion of the respective features within a printed part using input values from the experimental data.

Findings
The result from this investigation shows that to calculate the UTS of a partially filled FFF part, the calculation based on the conventional approach is not sufficient. A new meta-model is proposed which takes into account the geometry of the internal features to give an estimate of the strength of a partially filled printed part that is closer to the value of the strength of the material that is used for fabricating the part.

Originality/value
This paper investigates the tensile strength of a partially filled FFF printed part. The results have shown that the tensile strength of a partially filled part can be similar to that of a solid part, at a lower cost: shorter printing time and lower material usage. By taking into account the geometries within a printed part, the cross-sectional area can be accurately represented. The mathematical model which was developed would aid end-users to predict the tensile strength for a given set of input values of the process parameters.

Restructuring at Suzlon Energy Ltd
Authors: S.R. Vishwanath , Singh Kulbir , Arora Jaskiran , Prasad Durga 
Published: March 2017

Synopsis
The case highlights the ambitious growth strategy of Suzlon, an Indian company specializing in non-conventional (wind) energy. In 2007, Suzlon announced the acquisition of REpower of Germany, one of the top wind power companies in the world. It issued zero coupon and coupon bearing foreign currency (US dollar) convertible bonds (FCCB) amounting to $760 million to finance the acquisition. These bonds were listed in Singapore. Due to deteriorating business conditions the company experienced a sharp decline in profitability and stock price resulting in a debt overhang. At the same time, the Indian rupee depreciated from INR44 to INR55 leading to losses on largely unhedged, foreign currency coupon payments. The company had to restructure its capital structure to escape bankruptcy. Since FCCB holders did not agree to restructure the terms of the instrument, the company had to turn to senior lenders to restructure debt. Eventually Suzlon had to sell-off REpower to reduce leverage.

Research methodology
The case is based on interviews of market intermediaries and published information. The information relating to the restructuring has been taken from the information statement filed with the Securities Exchange Board of India and the Stock Exchanges. The timeline of events were constructed from the information available in company press releases. Financial statements and other details are from the documents filed with the regulators and supplemented with the information available in Prowess database. The stock price and stock market index data are from the websites of Bombay Stock Exchange and the National Stock Exchange of India. Exchange rates, inflation and interest rates have been taken from Bloomberg and the Reserve Bank of India website. Valuation inputs like multiples are from Prowess database and security analyst reports. Sources of information are documented appropriately in the case and instructor’s manual. Although we interviewed the investment bankers involved in the restructuring we have not included any private information in the case to preserve confidentiality.

Relevant courses and levels
This case can be used in a corporate finance course or in a module on debt restructuring in a corporate restructuring course or in the financing module in an advanced corporate finance course or in an International Finance course. It can also be used to teach an integrated approach to valuation and financing in a valuation course.

Theoretical bases
The case highlights the rationale for issuing FX convertible debt, parity conditions in international finance and the use of alternate valuation models.

The case highlights the situation when despite the administration of an appraisal process for the academic year 2012-2013, there was a uniform increment announced which was lower than the previous year’s increment on the pretext that the admission numbers for the next academic session were much low. The faculty and staff were in a dilemma of whether to continue in such an organization where the absence of a formal appraisal system would hamper their career progression or wait for another year for things to change.

Research methodology
This case is developed after an in-depth interview with the dean academics and the HR faculty of the Core Business School who headed the designing of the performance appraisal system and thereafter its implementation.

Relevant courses and levels
This case can be used for the elective course on performance management or human resource management course in MBA program.
Daily bread – a gourmet pursuit
Authors: Abhi Shinu , Venugopal Vasanti 
Published: March 2017

Synopsis
Arjun Sekri, a professional-turned-entrepreneur, set out to establish the first branded gourmet industrial bakery in Bengaluru, India in late 2002. His lack of experience in the unorganized food and beverages industry did not deter him from establishing a highly popular industrial and retail bakery chain called “Daily Bread”. The case is about his roller coaster ride in establishing a premium retail food brand in India. Though many of the stores did reasonably well, many things went wrong predominantly on the operations front due to the severe impact of global price inflation, manifested by high real estate rentals, raw material, packing and logistics costs and wage costs. After two years of rapid expansion, in order to curb the bleeding bottom line, Arjun decided to shut down all the newly created stores and production units except the one in Bengaluru which was doing well. By late 2009, the dilemma Arjun faced was what should he do next?

Research methodology
The case study is based on primary data collected from the protagonist and a few other stakeholders involved in the case along with secondary data from published sources.

Relevant courses and levels
Entrepreneurship courses at MBA level or executive programs.

Theoretical bases
The case deals with the life cycle management of a venture with special emphasis on opportunity evaluation, setting up, funding and stakeholders selection.
