Authors: Nam Ju Gang , Lee Jeong Min , Joo Ijin , Ahn Su Joa , Park Jin Young , Lee Kyoung Bun , Han Joon Koo 
Published: November 2017

Objective
The aim of this study was to determine the value of multi–detector row computed tomography (MDCT) in differentiating the small-duct (SD) and large-duct (LD) types of intrahepatic mass-forming cholangiocarcinomas (IMCCs) and predicting patient prognosis.

Methods
The 4-phase MDCT image findings of 82 patients with surgically confirmed IMCCs (60 SD-type and 22 LD-type IMCCs) were compared between 2 types using univariate and multivariate analyses. Overall survival rates for 78 patients with available information were compared using the Kaplan-Meier method.

Results
Arterial hyperenhancement, round or lobulated contour, and lack of bile duct encasement were significant MDCT features suggesting the SD type, and lymph node enlargement was significantly associated with the LD type (all P's < 0.05). The presence of those 3 SD-type-suggestive features (MDCT-suggested SD type) demonstrated high specificity (90.9% [20/22]) in differentiating the SD type. Patients of MDCT-suggested SD type without lymph node enlargement (n = 24) demonstrated significantly better overall survival than other groups.

Conclusions
Preoperative MDCT features of IMCCs can help differentiate the SD and LD types and predict patient prognosis.
Incidental Cardiac Findings in Non–Electrocardiogram-gated Thoracic Computed Tomography of Intensive Care Unit Patients: Assessment of Prevalence and Underreporting
Authors: Kuetting Daniel , Müller Andreas , Feisst Andreas , Luetkens Julian , Dabir Darius , Schild Hans H. , Thomas Daniel 
Published: November 2017

Purpose:
Cardiac findings frequently remain unreported on non–electrocardiogram (ECG)-gated computed tomography (CT). Although the clinical relevance of such findings may be limited in a general patient population, they may have significant impact in intensive care patients. Thus, the purpose of this study was to evaluate the prevalence, underreporting, and clinical relevance of incidental cardiac findings in intensive care unit (ICU) patients.

Materials and Methods:
Non–ECG-gated chest CT examinations of ICU patients were retrospectively analyzed for incidental cardiac findings. The findings were classified into 3 categories (A to C): category A findings, which carry potential for risk to life; category B findings, which have a potential for significant morbidity; category C findings, which have a possible effect on prognosis.

Results:
A total of 500 patients who underwent non–ECG-gated thoracic CT examinations were included. Of the 500 patients, 403 presented with 1443 cardiac findings. Of all cardiac findings, 37% were described in the initial written report. Sixty category A findings were detected, of which 48% were not mentioned in the report. Six hundred forty category B findings were detected, of which 77% were not described in the report. The remaining 743 findings were classified as category C, 55% of which were not reported in the report.

Conclusions:
The prevalence as well as the rate of underreporting of incidental cardiac findings in non–ECG-gated chest CT of ICU patients is very high. The results of this study underscore the importance of dedicated training for assessment of cardiac structures and conditions, which may be detected on non–ECG-gated chest CT.

Authors: Katlic Mark R. , Coleman JoAnn , Khan Kamran , Wozniak Susan E. , Abraham Joseph H. 
Published: November 2017

Objective:
To develop and validate a simple geriatric screening tool that performs as well as more complex assessments

Background:
Many tools that predict treatment risk in older adults are impractical for routine clinical use.

Methods:
We prospectively conducted comprehensive preoperative evaluations on 1025 patients age ≥75 years who presented to Sinai Hospital of Baltimore for major elective surgery, then retrospectively reviewed patients’ medical records for occurrence of postoperative outcomes. Using logistic regression modeling and receiver operating characteristic curve analysis we selected the best combination of simple tests, labeling this the Sinai Abbreviated Geriatric Evaluation (SAGE). The performance of the SAGE was then compared with 3 standard tools in its power to predict postoperative outcomes.

Results:
The SAGE is a statistically significant predictor of postoperative outcomes. Each unit decrease in SAGE score was significantly associated with a 51% (95% CI 1.30–1.77) increase in odds of a complication, a 2-fold increase in odds of postoperative delirium (95% CI 1.65–2.66), a 27% increase in odds of length of hospital stay >2 days (95% CI 1.10–1.47), a 54% increase in odds of a hospital readmission within 30 days (95% CI 1.25–2.88), and a 38% increase in odds of an unanticipated discharge to higher-level care (95% CI 1.18–1.61). We estimated the receiver operating characteristic curve area under the curve (AUC) for the SAGE of 0.69, 0.77, 0.73, 0.66, and 0.78 for the above outcomes, respectively. The SAGE performed as well in predicting postoperative outcomes as Fried's frailty phenotype, Charlson Comorbidity Index, and American Society of Anesthesiologists Physical Status Class (ASA).

Conclusion:
The SAGE performs as well as other geriatric evaluations that require equipment or memorization.
Postoperative Voiding Dysfunction: The Preferred Method for Catheterization
Authors: McDermott Colleen D. , Ryan Victoria , Pulver Ariel , Boutet Marianne 
Published: November 2017

Objectives
Bladder drainage can be achieved by clean intermittent self-catheterization (CISC), transurethral indwelling catheterization (TIC), or with a suprapubic tube (SPT). The primary objective of this study was to determine patient preference for catheter type in the management of potential voiding dysfunction after pelvic organ prolapse (POP) surgery.

Methods
Between 2012 and 2016, patients scheduled for POP surgery were recruited into the study. Before surgery, patients were informed of the potential for postoperative voiding dysfunction and the catheter choices were discussed. Each patient's choice was recorded along with baseline information, surgery performed, and perioperative details. After surgery, voiding dysfunction, length of catheter use, scores on a catheter satisfaction questionnaire, as well as uroflowmetry and urine culture testing were assessed.

Results
Of those recruited to the study (N = 150), 6.7% chose CISC, 7.3% chose TIC, and 86% chose SPT. Catheter satisfaction score 1 week after surgery was significantly better for SPT compared with CISC and TIC (P = 0.005). In addition, at week 1, 33% of CISC, 25% of TIC, and 13% of SPT had a PVR of more than 30% (P = 0.002) on uroflowmetry, and 33% of CISC, 50% of TIC, and 24% of SPT had a positive urine culture (P = 0.05).

Conclusions
This study has shown that patients prefer SPT over CISC and TIC for management of voiding dysfunction after POP surgery. Use of SPT showed better satisfaction rates, better uroflowmetry results, and lower infection rates 1 week after surgery. Patient preference is an important factor in this decision and can help facilitate a clinical approach.

Published: November 2017

The condensation reaction of acetophenone (1-phenylethan-1-one) with 2-nitrobenzaldehyde in the molten state yielded the expected chalcone, (E)-3-(2-nitrophenyl)-1-phenylprop-2-en-1-one, and, unexpectedly, the title compound, C30H22N2O6, which results from thesynhead-to-head [2 + 2] cycloaddition of the chalcone. The molecular structure of the dimer shows that the four benzene rings of the substituents are oriented in such a way that potential steric hindrance is minimized, whilst allowing some degree of intermolecular π–π interactions for crystal stabilization. In the molecule, one nitro group is disordered over two positions, with occupancies for each part of 0.876 (7) and 0.127 (7).

Published: November 2017

PurposeThe purpose of this paper is to explore and describe how research on quality management (QM) has evolved historically. The study includes the complete digital archive of three academic journals in the field of QM. Thereby, a unique depiction of how the general outlines of the field as well as trends in research topics have evolved through the years is presented.Design/methodology/approachThe study applies cluster and probabilistic topic modeling to unstructured data fromThe International Journal of Quality & Reliability Management,The TQM JournalandTotal Quality Management & Business Excellence. In addition, trend analysis using support vector machine is performed.FindingsThe study identifies six central, perpetual themes of QM research: control, costs, reliability and failure; service quality; TQM – implementation and performance; ISO – certification, standards and systems; Innovation, practices and learning and customers – research and product design. Additionally, historical surges and shifts in research focus are recognized in the study. From these trends, a decrease in interest in TQM and control of quality, costs and processes in favor of service quality, customer satisfaction, Six Sigma, Lean and innovation can be noted during the past decade. The results validate previous findings.Originality/valueOf the identified central themes, innovation, practices and learning appears not to have been documented as a fundamental part of QM research in previous studies. Thus, this theme can be regarded as a new perspective on QM research and thereby on QM.
Understanding the success of private universities
Authors: Hossain Mohammad Alamgir , Hossain Md Moazzem , Chowdhury Tajmin Hossain 
Published: November 2017

Purpose
A successful education system is a great asset for any society. However, what factors make an academic institution successful and how these factors interact with each other are not clear in literature. Therefore, the purpose of this paper is to develop and validate a model that explains success of private universities which entails clarification on theoretical understanding and explains the relationships among relevant variables.

Design/methodology/approach
Variables from information systems success models and marketing theories have been adapted in the context of private universities to theorize a conceptual model. In order to validate the model, this study employed quantitative approach. Survey data, collected from 326 respondents, were analysed using partial least squares algorithm.

Findings
The results suggest that: “curriculum quality”, “teaching competence”, “service facility”, and “service delivery” provided by a private university are positively related to “perceived value (PV)”, while students’ perceived satisfaction (SPS) is dependent on “service facility”; PV and SPS drive to students’ “intention for continued education (ICE)”, and ICE eventually improves quality of students’ lives. Additionally, PV and SPS are interrelated. The mediating roles of PV and SPS are also identified.

Research limitations/implications
Empirical data analyses confirm that improving quality of life through continued education represents an insightful theoretical lens for investigating success in higher education. To become successful in education business, maintaining both academic quality and service quality are important for a private university because they lead to student satisfaction and the overall PV of education.

Originality/value
This study is the first initiative that develops and validates a success model of private universities. The findings provide some guidelines for top managers in higher education to maximize their abilities to understand customers’ expectations in both strategic and operational settings.
Model of the port performance metrics in ports by integration six sigma and system dynamics
Authors: Ridwan Asep , Noche Bernd 
Published: November 2017

Purpose
The purpose of this paper is to design a model of the port performance metrics for improving the quality in ports by integration of six sigma and system dynamics (SD) approach.

Design/methodology/approach
The port performance is measured by the sigma value (SV), the process capability indices (PCIs), and the cost of poor quality (COPQ) as the performance metrics. A port is a complex system that requires SD as an appropriate tool to simulate the model dynamically. The performance metrics focus on measuring the port performance in the entire flow of material in the cargo handling process.

Findings
With this model, the changing of the SV, the PCIs, and the COPQ can be identified and analyzed the results to improve the performance in ports. These metrics are utilized to eliminate “waste” in the cargo handling process at ports. This waste consists of lost and damaged cargo, equipment and transporter breakdown, and equipment and transporter delay time. The port performance metrics model can assess the causal relationships in ports as a complex system.

Originality/value
Studies on integration between the six sigma model and SD in ports are few and relatively limited. The port’s performance can be measured directly using the SV, the PCIs, and the COPQ in the simulation. The port performance metrics model will give the decision makers to make some scenarios to contribute for the optimization of performance in ports.
Monitoring the process quality for multistage systems with multiple characteristics
Authors: Pan Jeh-Nan , Li Chung-I , Hsu Jun-Wei 
Published: November 2017

Purpose
The purpose of this paper is to provide a new approach for detecting the small sustained process shifts in multistage systems with correlated multiple quality characteristics.

Design/methodology/approach
The authors propose a new multivariate linear regression model for a multistage manufacturing system with multivariate quality characteristics in which both the auto-correlated process outputs and the correlations occurring between neighboring stages are considered. Then, the multistage multivariate residual control charts are constructed to monitor the overall process quality of multistage systems with multiple quality characteristics. Moreover, an overall run length concept is adopted to evaluate the performances of the authors’ proposed control charts.

Findings
In the numerical example with cascade data, the authors show that the detecting abilities of the proposed multistage residual MEWMA and MCUSUM control charts outperform those of Phase II MEWMA and MCUSUM control charts. It further demonstrates the usefulness of the authors’ proposed control charts in the Phase II monitoring.

Practical implications
The research results of this paper can be applied to any multistage manufacturing or service system with multivariate quality characteristics. This new approach provides quality practitioners a better decision making tool for detecting the small sustained process shifts in multistage systems.

Originality/value
Once the multistage multivariate residual control charts are constructed, one can employ them in monitoring and controlling the process quality of multistage systems with multiple characteristics. This approach can lead to the direction of continuous improvement for any product or service within a company.
Configuration of volume flexibility in Indian manufacturing firms: evidence from case studies
Authors: Mishra Ruchi 
Published: November 2017

Purpose
The purpose of this paper is to explore different drivers and volume flexibility strategies employed in manufacturing firms. It also examines contingent factors, which determine volume flexibility requirement in manufacturing firms.

Design/methodology/approach
Using a multi-case study approach, the study examines and analyses drivers, strategies and contingent factors that affect volume flexibility in four Indian manufacturing plants belonging to automobiles, auto ancillary, fashion apparel and electrical industry.

Findings
The empirical analysis suggests various drivers of volume flexibility and different strategies employed by firms to enhance flexibility. The study also illustrates various contingent factors that determine the need of volume flexibility in firms.

Research limitations/implications
The sample of the study is majorly confined to the northern region of India. Methodologically, the analysis is solely based on the qualitative data.

Practical implications
The study suggests practitioners to consider a range of contingent factors, while evaluating the need of volume flexibility in manufacturing plants. Rather than relying on a single strategy, a mix of strategies should be used to develop volume flexibility in firms.

Originality/value
The identification of a range of strategies employed by volume flexible firms as well as contingent factors that need to be evaluated before employing volume flexibility are the major contributions of this study.

Understanding climate change adaptation in Africa: key considerations
Authors: Abraham Ernest Mensah 
Published: November 2017

Purpose
The purpose of this paper is to synthesise lessons from research on adaptation to demonstrate that African countries can explore the opportunities and challenges inherent in climate variability and change.

Design/methodology/approach
The paper is a review work which synthesises lessons from relevant journal articles and other related documents. The literature was retrieved from Google and Google Scholar using search terms such as climate change, climate change and mitigation, climate change and mitigation in Africa, climate change adaptation and mitigation in Africa, climate change vulnerability, climate change impacts, among others. Various combinations of the search terms were also deployed. The journals were subjected to critical review and key lessons synthesised from them and reflections on their future implications in relation to climate risks and vulnerability presented.

Findings
Key lessons were synthesised and reflections on their future implications in relation to climate risks and vulnerability were presented. The evidence seems to suggest that countries in Africa recognise that it is time for them to take action on the impacts of climate change. The key lessons which emerge, going forward, are that climate change adaptation should be mainstreamed into development plans of nations. All efforts should be geared towards sustaining livelihoods of people. Key stakeholders also have a role to play in adaptation. The paper has indicated that although a lot has happened, there are areas that require strengthening and that should be the focus and priority of change and policy makers for the future.

Research limitations/implications
The paper is a synthesis and reflection of existing literature and it is possible that some of the dynamics may have changed since the paper was published.

Practical implications
The dynamics of climate change adaptation is understood. The approaches to adaptation are also explored. Areas worth prioritising in the discourse of adaptation studies have also been indicated.

Originality/value
The syntheses provided are the reflections of the author. The views of the researcher provide insights and understanding into the current adaptation debate.
Transdisciplinary approach to natural resource governance research: a conceptual paper
Authors: Yeboah-Assiamah Emmanuel , Muller Kobus , Domfeh Kwame Ameyaw 
Published: November 2017

Purpose
Natural resources in contemporary times are mostly managed by a collaborative governance approach which hinges on complex institutional designs (rules, norms and strategies). Many studies have been designed and carried out to assess collaborative governance, and the various institutional designs underpinning them. The purpose of this paper is to unpack the methodological gaps in natural resource governance research (with emphasis on co-management) and to conceptualise the appropriateness of Transdisciplinary (TD) research approach.

Design/methodology/approach
The paper adopts a critical stage review of relevant theoretical and empirical literature on natural resource governance. It discusses the complexities inherent in natural resource governance and juxtaposes these with the inherent weaknesses in methodologies employed by existing studies on the concept. The authors make a case for a TD research methodology that links scientists, practitioners and society in a joint problem design and solution process.

Findings
The authors register a “fuzziness” of the collaborative governance phenomenon but observe a methodological gap in existing studies on the concept. This paper discusses the complexities inherent. The paper describes TD as a “tailor-made approach” to solving complex societal issues and makes a case for its adoption in natural resource governance studies.

Research limitations/implications
This standalone paper is largely conceptual and not linked to any primary data; this notwithstanding, it synthesizes from both empirical and theoretical literature which would help shape future research endeavours in natural resource governance context.

Practical implications
With TD study oriented towards an epistemologically flexible approach, perspectives from different social and academic actors are integrated in this expanding field of research to address societal problems.

Originality/value
The paper provides a conceptual framework designating how actors interact in the TD research process as well as a “four-phase” approach in carrying out a TD research.
