Developing causal loop diagrams (CLDs) involves identifying stakeholders and endogenous variables and formulating variable causal relationships. Traditionally, the CLDs are developed mainly using a qualitative approach such as literature review, observations and interviews with stakeholders. However, modellers may question which stakeholders should be approached, whether the relevant variables are selected, and what to do when stakeholders perceive different variable relationships in the CLDs differently. Applying in a case study, this research proposes a multi-method approach by combining both quantitative and qualitative methods to select stakeholders, identify endogenous/exogenous variables, and develop the CLDs. The proposed quantitative method is expected to provide modellers with a justifiable stakeholder and variable selection process. The method also highlights possible hidden variables and relationships, which were further explored with a traditional qualitative approach.

PurposeThis paper aims to extend the customer complaint behaviour (CCB) knowledge by introducing a visual technique called customer complaint journey mapping as a means of capturing and understanding multi-faceted service failures involving multiple actors.Design/methodology/approachResearch participants were trained to record contemporaneous accounts of future dissatisfactory dining experiences. Minimising issues of memory recall whilst faithfully capturing complainants' raw emotions. These recordings formed the basis for follow up interviews, based on the critical incident technique.FindingsThe central finding of this paper was how other actors outside of the traditional service dyad played a dynamic role in co-creating a complainants' emotions and subsequent behaviours.Practical implicationsThe resulting customer complaint maps give deep insights into the complex social dynamics involved in CCB, providing a powerful tool for both researchers and staff responsible for recovery strategies.Originality/valueThe mapping framework provides an innovative means of capturing the actual complaint experiences of customers and the role of other actors, utilising a multi-method approach designed to address various limitations of existing CCB research.

Purpose This study aims to develop a method of segmenting markets by using the functional approach to attitudes. The adopted approach identifies and groups individuals based on what functions their held attitudes serve for them. Specific marketing mixes can, thus, be designed for each functional profile. Design/methodology/approach The multi-method approach adopted consists of a qualitative assessment of consumers’ attitudinal functions in the physical fitness context and the development of an instrument to identify the distribution of attitudinal function segments in the same context. Findings A valid and reliable instrument that can be used to segment a market based on functional profiles is developed. Practical implications The outlined method provides a method for practitioners to identify existing functional segments, thus creating marketing mixes based on these functional segments and, ultimately, maximizing the value created for each segment. Originality/value The value in this research lies in the integration of old concepts (functional approach and scale development) to solving a new problem. The functional approach reaches deep to determine “why attitudes are held” vs simply “what attitudes are held”. Operationalization difficulties led to the abandonment of the approach. This research, thus, contributes theoretically by actually operationalizing the functional approach via a scale development, and using the operationalized form as a new means for segmenting markets.

The multi-symplectic integrator, as a numerical integration approach with symmetry, is known to have the characteristic of preserving the qualitative features and geometric properties of certain systems. Using the multi-symplectic integrator, the numerical simulation of the Gaussian solitary wave propagation of the logarithmic Korteweg–de Vries (logarithmic-KdV) equation was investigated. The multi-symplectic formulation of the logarithmic-KdV equation was explored by introducing some intermediate variables. A fully implicit version of the centered box scheme was used to discretize the multi-symplectic equations. In addition, numerical experiments were carried out to show the conservative properties of the proposed scheme.

This article suggests a new methodological model for the study of hybrid media events with global appeal. This model, developed in the project on the 2015 <em>Charlie Hebdo</em> attacks in Paris, was created specifically for researching digital media—and in particular, Twitter. The article is structured as follows. Firstly, the methodological scope is discussed against the theoretical context, e.g. the theory of media events. In the theoretical discussion, special emphasis is given to i) disruptive, upsetting, or disintegrative media events and hybrid media events and ii) the conditions of today’s heterogeneous and globalised media communication landscape. Secondly, the article introduces a multi-method approach developed for the analysis of hybrid media events. In this model, computational social science—namely, automated content analysis (ACA) and social network analytics (SNA)—are combined with a qualitative approach—specifically, digital ethnography. The article outlines three key phases for research in which the interplay between quantitative and qualitative approaches is played out. In the first phase, preliminary digital ethnography is applied to provide the outline of the event. In the second phase, quantitative social network analytics are applied to construct the digital field for research. In this phase, it is necessary to map a) what is circulating on the websites and b) where this circulation takes place. The third and final phase applies a qualitative approach and digital ethnography to provide a more nuanced, in-depth interpretation of what (substance/content) is circulating and how this material connects with the ‘where’ in the digital landscape, hence constituting links and connections in the hybrid media landscape. In conclusion, the article reflects on how this multi-method approach contributes to understanding the workings of today’s hybrid media events: how they create and maintain symbolic battles over certain imagined constructs of social imaginaries of solidarity, belonging, contestation, and exclusion, a topic of core value for the theory of media events.

Purpose The purpose of this paper is to define the individual leadership competencies that are necessary to implement and sustain lean systems, based on a multi-method approach. Design/methodology/approach Data collection involved a literature review of lean competencies, interviews with four experts from the university and the industry, and an empirical survey answered by 91 respondents, who represented companies from several sectors. These techniques provided a mix of qualitative and quantitative data, which set a basis for identifying a list of competencies and discussing its validity. Findings In total, 16 lean leadership competencies were identified and validated, in terms of content validity, face validity, and predictive validity. Regarding this latter validity type, the survey results indicated that the competencies are positively associated with key operational performance indicators, organizational maturity level of lean, and leaders’ experience with lean systems. Practical implications The identified list of competencies may be a basis for the development of formal lean leadership development programs. The list may also support the design of tools for assessing the competencies of leaders in lean companies. Originality/value A list of 16 lean leadership competencies was developed based on a verifiable research method that used a mix of data collection techniques. This methodological approach is a distinctive characteristic in comparison with earlier studies, which did not include an empirical validation of the competencies.

This paper describes a conceptual framework for developing new distribution structures. In real life decision‐making, optimal regions to locate a distribution center take into account both quantitative and qualitative factors. An adjusted kuehn‐Hamburger model is suggested to minimize transport and location costs and a Grid model is used as an alternative approach in case of missing data. The outcome is refined on quantitative and qualitative criteria by application of the Electre method. This framework is applied to a major telecom company's European distribution.

Abstract The ultimate goal of this study is to develop a comprehensive and competitive management system to enhance resilience capability of supply chains. In addition, the study aims to identify and eliminate barriers affecting resilience by identifying the factors may cause trouble in the near future. The theoretical framework was established to summarize the significant finding in the area of resilient supply chain and as a guideline for the empirical part. A qualitative approach based on multi criteria decision making process has been adopted in order to gather data through in-depth interviews. The developed method to evaluate resilience capability through supply chains piloted in a sample of five companies involved in an automotive supply chain.

Abstract. A high rocky slope is an open complex giant system for which there is contradiction among different influencing factors and coexistence of qualitative and quantitative information. This study presents a comprehensive intelligent evaluation method of high rocky slope safety through an integrated analytic hierarchy process, extension matter element model and entropy weight to assess the safety behavior of the high rocky slope. The proposed intelligent evaluation integrates subjective judgments derived from the analytic hierarchy process with the extension matter model and entropy weight into a multiple indexes dynamic safety evaluation approach. A combined subjective and objective comprehensive evaluation process, a more objective study, through avoiding subjective effects on the weights, and a qualitative safety assessment and quantitative safety amount are presented in the proposed method. The detailed computational procedures were also provided to illustrate the integration process of the above methods. Safety analysis of one high rocky slope is conducted to illustrate that this approach can adequately handle the inherent imprecision and contradiction of the human decision-making process and provide the flexibility and robustness needed for the decision maker to better monitor the safety status of a high rocky slope. This study was the first application of the proposed integrated evaluation method in the safety assessment of a high rocky slope. The study also indicated that it can also be applied to other similar problems.

Most of the real-world multicriteria decision-making (MCDM) problems contain a mixture of quantitative and qualitative criteria; therefore quantitative MCDM methods are inadequate for handling this type of decision problems. In this paper, a MCDM method based on the Fuzzy Sets Theory and on the Analytic Hierarchy Process (AHP) is proposed. This method incorporates a number of perspectives on how to approach the fuzzy MCDM problem, as follows: (1) combining quantitative and qualitative criteria; (2) expressing criteria pair-wise comparison in linguistic terms and performance of the alternative on each criterion in linguistic terms or exact values when criterion is qualitative or quantitative, respectively; (3) converting all the assessments into trapezoidal fuzzy numbers; (4) using the difference minimization method to calculate the local weight of criteria, employing the algebraic operations of fuzzy numbers based on the concept of α-cuts; (5) calculating the global weight of criteria and the global performance of each alternative using geometric mean and the weighted sum, respectively; (6) using the centroid method to rank the alternatives. Finally, an illustrative example on evaluation of several combined cooling, heat, and power production systems is used to demonstrate the effectiveness of the proposed methodology.

Purpose – The purpose of this paper is to select the best scaling coefficient during the quantitative-qualitative conversion. Design/methodology/approach – Cloud model can describe the qualitative concept of randomness and fuzziness, achieve uncertain transition between qualitative and quantitative in the field of multi-criteria group decision and has been receiving widespread attention. This paper discusses scale conversion issues of the cloud model when evaluating qualitative information. In order to improve the accuracy of the evaluation on multi-attribute decision problems based on uncertainty of natural linguistic information, this paper proposes a method of self-testing cloud model based on a composite scale (with the exponential scale and the scale as a basis). Findings – Through experimental verification results show that under composite scale, the best suitable selection of can effectively improve the accuracy and reliability of decision results. Originality/value – This research presents a new approach to determine the suitable value for coefficient based on uncertain knowledge of natural multi-criteria group decision making, and gives concrete steps and examples. This method has positive significance to improve the quality of qualitative and quantitative conversion based on cloud model.

Abstract Project 1: Community Health Advocates participated in a photovoice project that evolved into an invited installation at the Alabama Contemporary Art Center, giving statewide exposure to health issues in communities in South Alabama that had been identified as those with the highest health disparities. The context of the project was a multi-generational approach to community health advocacy. Project 2: This project focused on employing CBPR methods in Cambodian and Laotian immigrant communities in South Alabama to discover barriers to disaster preparedness, response, and recovery and to better understand the intersections of culture, spirituality, and social justice along the path to community empowerment and resiliency. Community engagement in the development of emergency plans is typically at the organization-to-organization level. This paper analyzes multi-generational, multi-disciplinary, multi-method approaches using qualitative data to build effective strategies for advocacy through community engagement in research.

This article developed a multi-methods approach in the particular branch of Communication Studies (fandom studies) to understand the transcultural fans' engagement. It has creatively deployed three research methods to unpack the Chinese fans of a British TV series- Sherlock. Research methods of autoethnography, netnography and qualitative interviews have been largely employed to test the loyalty of the author as an acafan, Chinese fans' online activity and fans' self-disclosure as a self-claimed fan. The multi-methods worked effectively to help draw the conclusion that the self-claimed fans were not fans as what the existing literature has defined. The creative combination of three methods greatly facilitated the future research of fan studies to identify fans as a focal point of the research. Este artículo expone un enfoque multi-método en la rama específica de los estudios de comunicación sobre el fenómeno fandom para entender el engagement con fans transculturales. Así, se han desarrollado tres métodos de investigación para analizar a los fans chinos de la serie de televisión británica Sherlock. La autoetnografía, la netnografía y la entrevistas cualitativas se han empleado en gran medida para probar la lealtad del autor como acafán (un académico que también es fan), la actividad online de los fans chinos y la actividad divulgadora de los que se autoproclaman como fans. Estos distintos métodos nos permiten llegar a la conclusión de que un porcentaje significativo de los que se autoproclaman fan, no lo hacen en el sentido estricto utilizado por la literatura existente. La combinación de los tres métodos facilita enormemente las futuras investigaciones sobre los fans, ubicándolos en el punto central de la investigación.

Although much has been written about the process of party system institutionalization in different regions, the reasons why some party systems institutionalize while others do not still remain a mystery. Seeking to fill this lacuna in the literature, and using a mixed-methods research approach, this article constitutes a first attempt to answer simultaneously the following three questions: (1) What specific factors help party systems to institutionalize (or not)? (2) What are the links (in terms of time and degree) as well as the causal mechanisms behind such relationships? and (3) how do they affect a particular party system? In order to do so, this article focuses on the study of party system development and institutionalization in 13 postcommunist democracies between 1990 and 2010. Methodologically, the article innovates in five respects. First, it continues the debate on the importance of “mixed methods” when trying to answer different research questions. Second, it adds to the as yet brief literature on the combination of process tracing and qualitative comparative analysis. Third, it constitutes the first attempt to date to use a most similar different outcome/most different same outcome procedure in order to reduce causal complexity before undertaking a crisp-set qualitative comparative analysis. Third, it also shows the merits of combining both congruence and process tracing in the same comparative study. Finally, it also develops a novel “bipolar comparative method” to explain the extent to which opposite outcomes are determined by reverse conditions and conflicting intervening causal forces.

PurposeA lot is known about systemic barriers to broadening participation (BP) in STEM. Empirical research has demonstrated the existence and impact of implicit bias, stereotype threat, and micro-aggressions on a sense of belonging, organizational productivity and leadership opportunities. We also know that achieving greater participation of women and faculty of color in the STEM disciplines is complicated and depends on altering complex and multi-layered interactions between activities and actors. Further, because researcher and institutional goals vary as a function of target population and context, generalizable models can struggle in the face of larger BP efforts. Through the authors experience as an NSF ADVANCE-IT awardee, the authors believe that a dynamic, multi-scaled and organizational level approach is required to reflect the reciprocal dialogue among research questions, best practices, tailored applications and quantifiable goals. The authors describe several examples of research, programming activities and program evaluation that illustrate this approach. In particular, the authors describe both the programming successes and challenges, with the aim of helping others to avoid common mistakes by articulating very broad and, the authors’ hope, generalizable “lessons learned.” The paper aims to discuss these issues.Design/methodology/approachTo better understand the barriers for women in STEM, the authors utilized an iterative methodology. Specifically, the authors conducted a social network analysis, an exit survey of departed faculty, longitudinal analysis of career trajectories and research productivity, and a survey on the interaction between values and climate.FindingsThe analyses suggest three strategies better retain women in STEM: improve women’s professional networks; re-aling policy documents and departmental practices to better reflect faculty values; and improve departmental climate.Practical implicationsThe pay-off for using this more complex research approach to triangulate onto specific challenges is that the interventions are more likely to be successful, with a longer-lasting impact.Originality/valueWith continuous institutional research, metric refinement, and program evaluation the authors are better able to develop targeted programming, policy reform, and changes in institutional practice. The interventions should result in permanent institutional and systemic change by integrating multi-method qualitative and quantitative research into BP practices, which the authors couple with longitudinal analysis that can quantify success of the authors’ efforts.

This study used both qualitative and quantitative data to test hypotheses related to consumers’ motivations to engage in impulse buying. A grounded theory approach was used to develop hypotheses from in‐depth interviews. These hypotheses were tested by the collection and analysis of survey data. Data support the theory that impulse buying is a common method of product selection, in part, because the shopping act and impulsive product selection provide hedonic rewards. Further information‐processing overload confounds product selection, reinforcing the rewards to be obtained from alternative section heuristics, like impulse buying.

Purpose The purpose of this study is to provide a comprehensive framework for analyzing risk factors in oil and gas projects. Design/methodology/approach This paper consists of several sections. In the first section, 19 common potential risks in the projects of Pars Oil and Gas Company were finalized in six groups using the Lawshe validation method. These factors were identified through previous literature review and interviews with experts. Then, using the “best-worst multi-criteria decision-making” method, the study measured the weights associated with the performance evaluation indicators of each risk. Consequently, failure mode and effects analysis (FMEA) and the grey relational analysis (GRA)-VIKOR mixed method were used to rank and determine the critical risks. Finally, to assign response strategies to each critical risk, a zero-one multi-objective mathematical programming model was proposed and developed Epsilon-constraint method was used to solve it. Findings Given the typical constraints of projects which are time, cost and quality, of the projects that companies are often faced with, this study presents the identified risks of oil and gas projects to the managers of the oil and gas company in accordance with the priority given in the present research and the response to each risk is also suggested to be used by managers based on their organizational circumstances. Originality/value This study aims at qualitative management of cost risks of oil and gas projects (case study of Pars Oil and Gas Company) by combining FMEA, best worst and GRA-VIKOR methods under fuzzy environment and Epsilon constraints. According to studies carried out in previous studies, the simultaneous management of quantitative and qualitative cost of risk of oil and gas projects in Iran has not been carried out and the combination of these methods has also been innovated.

There is an urgent need to develop and test health promotion strategies that both address health disparities and elucidate the full impact of social, cultural, economic, institutional, and political elements on people's lives. Qualitative research methods, such as life history interviewing, are well suited to exploring these factors. Qualitative methods are also helpful for preparing field staff to implement a social contextual approach to health pro-motion. This article reports results and application of findings of life history interviews conducted as part of intervention planning for the Harvard Cancer Prevention Program Project, “Cancer Prevention in Working-Class, Multi-Ethnic Populations.” The salient themes that emerged from interviews with a multi-ethnic, purposive sample are centered on six construct domains: immigration and social status, social support, stress, food, physical activity, and occupational health. Insights gained from thematic analysis of the interviews were integrated throughout intervention and materials development processes.

Construction contractors have a great role in terms of operation work properly in construction project management. An effective contractor selection is most important to the success of any construction projects. Contractor selection is a multi criteria decision making problem which includes qualitative and quantitative characteristics. For the contractor selection problem, this study proposes a combined decision approach, which employs analytic hierarchy process (AHP) and Fuzzy Technique Ordered Preference by Similarity to the Ideal Solution (TOPSIS) methods. In the proposed approach, AHP is used to determine the weights of selection criteria, and Fuzzy TOPSIS is used to select appropriate contractor alternative. Additionally, a real case study in construction industry is presented to illustrate the application of the proposed approach.

Abstract This multi-method research explores the challenges family practitioners and long-term care facilities face when they work together. It seeks to understand how different responses to these challenges may influence the delivery of care. Whilst different services have their own values, aims, structures and processes, all are contending with constrained resources and frequent organisational change. Our findings from a large qualitative study and analysis of routine health data are organised around the micro (individual), meso (organisational) and macro (system) factors that influence the organisation and delivery of resident care. In this presentation, we draw out the interplay between these levels, and how each shapes and is shaped by the changing demands and nature of care. This presentation will bring new insights into primary care for long-term care facilities, through the perspectives of those who experience and provide care in that setting.

In this article, we suggest and discuss a qualitative, multi-methods approach to data collected on smartphones as a way of uncovering a user-centred perspective on cross-media communication. As an individualised multimedia device, the smartphone represents a relevant starting point for studying individual users’ cross-media practices. Moreover, the technological affordances of the smartphone, including built-in sensors and GPS tracker as well as features for capturing photo, audio and video material, enable the collection of a wide range of data. These properties have mainly been approached from a quantitative point of view focusing on automatically logged use data as an alternative to, for instance, survey data. Complementing this evidence, we argue that a qualitative, multiple-method approach to data collected on smartphones provides crucial insight into the contexts and everyday practices of cross-media communication.

36 Background: As healthcare becomes increasingly complex, research needs to take into account multi-level interactions that contribute to public health issues. One such area ripe for multi-level investigation is cancer survivorship care, illuminated in the 2006 Lost in Transition Institute of Medicine report on cancer survivors. We have developed a novel method that aims to understand barriers and facilitators of cancer survivorship from multiple levels, including community factors, medical system features, and policy and environmental influences. Methods: Our method, focused Rapid Assessment Process (fRAP), utilizes mixed methods at multiple levels to better understand cancer survivorship care with a primary care lens. fRAP begins with Geographic Information Systems (GIS) to map variables relevant to cancer survivorship care, such as cancer mortality rates, insurance coverage, and oncology and primary care provider sites. Qualitative participant observation and semi-structured interviews of informants from each level are then undertaken to better understand how cancer survivorship care is delivered within a county or census tract. Lastly, modifiable contextual factors from all levels are identified, as potential future environmental policy change targets. Results: As a development and pilot of our novel fRAP, we have designed, tested, revised and retested our methods over the last 3 years within the framework of two national grant-funded studies on cancer survivorship in primary care. Preliminary modifiable factors of interest affecting cancer survivorship care have been identified for future dissemination. The newest and current iteration of our methods has focused on utilizing GIS specifically to identify hot spots of cervical cancer mortality disparities in order to provide the richest contextual environment for subsequent qualitative inquiry into survivorship care. Conclusions: fRAP is a novel mixed method that has potential to identify modifiable barriers and facilitators of high-quality cancer survivorship care nationally, and may aid in policy improvements in health and healthcare delivery for survivors.

Underwater images are firmly low in quality by a mixture of noise, wavelength dependency, and light attenuation. This paper depicts an effective strategy to improve the quality of degraded underwater images. Existing methods for dehazing in the literature considering dark channel prior utilize two separate phases for evaluating the transmission map (i.e., transmission estimation and transmission refinement). Accurate restoration is not possible with these methods and takes more computational time. A proposed three-step method is an imaging approach that does not need particular hardware or underwater conditions. First, we utilize the multi-layer perceptron (MLP) to comprehensively evaluate transmission maps by base channel, followed by contrast enhancement. Furthermore, a gamma-adjusted version of the MLP recovered image is derived. Finally, the multi-scale fusion method was applied to two attained images. The standardized weight is computed for the two images with three different weights in the fusion process. The quantitative results show that significantly our approach gives the better result with the difference of 0.536, 2.185, and 1.272 for PCQI, UCIQE, and UIQM metrics, respectively, on a single underwater image benchmark dataset. The qualitative results also give better results compared with the state-of-the-art techniques.</span></span>

OBJECTIVES/SPECIFIC AIMS: Explore perceptions of Flint stakeholders on the water crisis regarding trust and the capacity of faith and community-based organizations providing public health services to address community needs. Analyze the community’s voice shared at (1) 17 key community communications (community/congressional meetings and events), and (2) during 9 focus group sessions, in which residents, faith-based leadership and other stakeholders discuss issues and concerns on the Flint Water Crisis, and recommend ways to address them. Develop a framework that defines core theories, concepts and strategies recommended by the community to help rebuild trust and the quality of life in Flint, Michigan, and support other communities experiencing environmental stress. METHODS/STUDY POPULATION: Study population: faith-based leaders, seniors, youth, Hispanic/Latino and African American stakeholders, and others experiencing inequities in the city of Flint. Convene 9 focus group sessions (recorded and transcribed) to learn community perceptions on trust and ways to address it. Validate accuracy of the transcriptions with community consultants to reconcile any inaccurate information. Through a community engaged research (CEnR) process, review and analyze qualitative data from the 9 focus group sessions, and quantitative data from 2 surveys documenting (1) demographic backgrounds of focus group participants, and (2) their perceptions on trust and mistrust. Prepare a codebook to qualitatively analyze the focus group data summarizing community input on trust, mistrust, changes in service delivery among community and faith-based organizations, and ways to re-build trust in the city of Flint. Transcribe the community’s voice shared during 17 key events, identified by a team of community-academic stakeholders (i.e., UM Flint water course, congressional and community events, etc.), in which residents and other stakeholders discuss issues and concerns on the Flint Water Crisis, and recommend ways to address it. Qualitatively analyze the transcriptions, using a CEnR process to prepare a codebook on key themes from the community’s voice shared at these events, and recommendations on ways to address it. Compare and contrast findings between the two codebooks developed from (1) the focus group data and (2) qualitative analysis of community voice during public meetings and events. Synthesize this information into a framework of core theories, concepts and rebuilding strategies for Flint, Michigan. RESULTS/ANTICIPATED RESULTS: It is important to note many undocumented immigrant populations in Flint fear deportation and other consequences, hampering their ability to obtain service and provide community voice. Through our purposive sampling approach, we will hear from community voices not often included in narratives (i.e., seniors, youth, Hispanic/Latino residents). The presentation will present findings documenting levels of trust and mistrust in the city of Flint; and a framework of recommendations, core theories and concepts on ways to reduce, rebuild and eliminate stress that will be helpful to other communities experiencing distress. DISCUSSION/SIGNIFICANCE OF IMPACT: To our knowledge, levels of trust and mistrust in Flint have not been documented thus far. We will compare and contrast common themes presented by the community at public meetings and events with themes presented in our focus group effort on trust. Faith and community-based providers were among the first responders to the Flint Water Crisis. The effort will also share perceptions on changes in public health service delivery, and observations on preparedness for these roles that occurred among community and faith-based providers. Finally, the effort will (1) support the design of a research agenda, (2) define a framework of core theories, concepts and recommendations developed by the community to help rebuild trust in Flint, Michigan; and (3) support other communities addressing environmental distress.

The criteria of GB/T 19580 are listed in form of linguistic term and its scoring system lacks of interim between adjacent grades. When the criteria are used in quality performance assessment, it will deal with large of qualitative indicators’ measurement and synthesis. The linguistic cloud model is introduced to implement the transition between qualitative criteria and quantitative measurement, and the evaluation approach of cloud center gravity is used to measure the change of multi-dimensional synthetic cloud. The degree of deviation θ is used to weigh the deflection between actual quality performance and best practice. Finally, a case is discussed to demonstrate the method proposed in this paper.

Purpose – Thematic coding is a common form of qualitative analysis, yet identification of “codes” can limit understanding by directing the researcher to formulated categories rather than inviting exploration of what else the data may be trying to convey. Since categorization is an essential component of language and can scarcely be avoided, the purpose of this paper is to propose a polyphonic approach as a way to add texture and nuance. In polyphonic coding, text is coded several times along various dimensions of interest; these independently coded versions are then superimposed to identify patterns and relationships, allowing a multi-lensed view of the data as both forest and trees. Design/methodology/approach – Polyphonic coding is applied to a specific interview in order to illustrate how the method can be utilized in a three-step process: in vivo coding from several independent perspectives (role, relational movement, and vocal mannerism), merging the perspectives, and “plugging in” to theory. Findings – Polyphonic coding reveals relationships among the perspectives that point to an over-arching theme (in the example used) of a struggle for control. Research limitations/implications – This approach offers a way to code verbal, tonal, and somatic data as a means of understanding the construction and negotiation of identity in the relational context of qualitative research. Practical implications – This approach promotes a flexible, expanded use of data analysis software. Originality/value – The metaphor of a musical motet is used to describe a multi-faceted approach to qualitative analysis that can help to mitigate some of the pitfalls of typical thematic coding.

In feminist media studies, the growing body of research on media production has indicated that journalism remains divided along gender lines. The purpose of this study is to address the lack of relevant multi-method research on gender inequality in journalism. To assess the structural position of women in the journalistic workforce, the authors conducted a large-scale survey of journalists in Belgium. The survey results were explored in more depth by conducting qualitative interviews with 19 female journalists. The analysis confirms the existence of all traditional barriers that women journalists experience. The added value of this study is that it enumerates several additional difficulties, and offers insight into the strategies that the respondents use to deal with gender-related career obstacles. These strategies were associated with the degree of flexibility in the newsroom for journalists with children, the choice to work part-time or freelance, and the use of new communication technologies.

PurposeSince the dawn of leadership research, generations of scholars have looked at the topic through the lenses of leader personalities and traits, their behaviour, the situation they are in and their relations with co-workers. Same as with ideology waves in managerial discourse and though sailing under different flags, many of the above “classical” foci reverberate in “modern” organisational literature. The authors argue, however, that relatively little effort has been put into what we label as “organisational embeddedness of leadership” (OEL). The authors here focus on the role of institutionalising leadership within the setting of “poly-contextual” organisational frameworks.Design/methodology/approachAddressing the ambiguity of previous OEL research with fresh primary data from Germany, the authors present a clear-cut five-dimensional, 15-items construct. The authors’ empirical validation rests on (1) two independent qualitative studies and (2) three independent quantitative investigations computing exploratory (N = 61) and confirmatory (N = 172) factor analysis as well as a regression analysis (N = 131).FindingsStructural equation modelling results indicate a single-factor model with five sub-dimensions consisting of leadership training and career development, leadership alignment, evaluation and feedback, implementation of employee interviews and supporting resources for leadership.Originality/valueThis work contributes to a broader understanding of “leadership emergence and development” (LED) from an organisational perspective. The limitations of the present article call for a lively debate on OEL and may illuminate some promising future research avenues.

The fuzzy linguistic approach provides favorable outputs in several areas, whose description is relatively qualitative. The encouragement for the utilization of sentences or words instead of numbers is that linguistic characterizations or classifications are usually less absolute than algebraic or arithmetical ones. In this research article, we animate the m-polar fuzzy (mF) linguistic approach and elaborate it with real life examples and tabular representation to develop the affluence of linguistic variables based on mF approach. As an extension of the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method, we develop an m-polar fuzzy linguistic TOPSIS approach for multi-criteria group decision-making (MCGDM). It is used to evaluate the best alternative, to get more authentic and comparable results and to handle the real life problems of having multi-polar information in terms of linguistic variables and values. In this approach decision-makers contribute their estimations in the form of linguistic term sets. To show the efficiency and compatibility of the proposed approach, we compare it with the m-polar fuzzy linguistic ELECTRE-I (Elimination and Choice Translating Reality) approach. Finally, we draw a flow chart of our proposed approach as an algorithm and generate a computer programming code.

Abstract Focusing on the conceptualization of a whole university approach, this paper reports on an international qualitative study that explored vice-chancellors’ and network members’ understanding of and commitment to Health Promoting Universities, examined perspectives on leadership and investigated the Okanagan Charter’s potential to catalyse whole university leadership and change. A multi-method qualitative approach was used: semi-structured interviews and focus groups were conducted face-to-face with vice-chancellors (n = 12) and Health Promoting University co-ordinators who were members of the UK Healthy Universities Network (n = 8); telephone interviews were conducted with a mix of UK and non-UK Health Promoting University co-ordinators (n = 5) and two online questionnaires were distributed to non-UK network co-ordinators (n = 6) and non-UK Health Promoting University co-ordinators (n = 10). Through thematic analysis, a number of key themes emerged that build a new conceptualization of the whole university approach (see Figure 1): building a broad understanding and framing of health; developing a supportive ethos and culture; embedding health into the university and joining up areas of work; focusing on the whole population and facing challenges and seizing opportunities. The study elicited rich and wide-ranging views from multiple stakeholders from universities and networks across four continents, confirming Health Promoting Universities as a truly global movement. Looking ahead, there are clear opportunities and challenges. First, the media narrative of a student mental health ‘crisis’ has focused universities’ attention on ‘health’, but from a single issue ‘illness’ perspective. This risks detracting from the whole system Health Promoting Universities approach. Second, even with the Okanagan Charter inspiring individuals and universities, there are still major challenges in translating the rhetoric of whole system approaches into meaningful action within large, complex and culturally diverse organizations.

Multi-criteria decision support systems are used in various fields of human activities. In every alternative multi-criteria decision making problem can be represented by a set of properties or constraints. The properties can be qualitative & quantitative. For measurement of these properties, there are different unit, as well as there are different optimization techniques. Depending upon the desired goal, the normalization aims for obtaining reference scales of values of these properties. This paper deals with the multi-attribute Complex Proportional Assessment of alternative. In order to make the appropriate decision and to make a proper comparison among the available alternatives Analytic Hierarchy Process (AHP) under fuzziness and COPRAS method with grey numbers has been used. The uses of AHP is for analysis the structure of the project selection problem is used under fuzziness and to assign the weights of the properties and the COPRAS-G method is used to obtain the final ranking and select the best one among the projects. To illustrate the above mention methods survey data on the expansion of optical fiber for a telecommunication sector is reused. The decision maker can also used different weight combination in the decision making process according to the demand of the system.COPRAS-G method is used to evaluate the overall efficiency of a project with the criterion values expressed in terms of intervals. It is based on the real conditions of decision making and applications of the grey number theory.

Background: Evaluations of complex interventions compared to usual care provided in palliative care are increasing. Not describing usual care may affect the interpretation of an intervention’s effectiveness, yet how it can be described remains unclear. Aim: To demonstrate the feasibility of using multi-methods to describe usual care provided in randomised controlled trials (RCTs) of complex interventions, shown within a feasibility cluster RCT. Design: Multi-method approach comprising usual care questionnaires, baseline case note review and focus groups with ward staff completed at study end. Thematic analysis of qualitative data, descriptive statistics of quantitative data, followed by methodological triangulation to appraise approach in relation to study aim. Setting/participants: Four general medical wards chosen from UK hospitals. Purposive sampling of healthcare professionals for usual care questionnaires, and focus groups. Review of 20 patients’ notes from each ward who died during admission or within 100 days of discharge. Results: Twenty-three usual care questionnaires at baseline, two focus groups comprising 20 healthcare professionals and 80 case note reviews. Triangulation of findings resulted in understanding the usual care provided to the targeted population in terms of context, structures, processes and outcomes for patients, families and healthcare professionals. Usual care was described, highlighting (1) similarities and embedded practices, (2) heterogeneity and (3) subtle changes in care during the trial within and across sites. Conclusions: We provide a feasible approach to defining usual care that can be practically adopted in different settings. Understanding usual care enhances the reliability of tested complex interventions, and informs research and policy priorities.

This work presents a qualitative measurement of anterior segment photographed images (ASPIs) to identify between normal eyes and eyes with pterygium and pinguecula through Otsu multi-thresholding approach without contrast enhancement. In addition, we also propose a mobile screening framework of ASPIs through smartphones. ASPIs were directly sent to the cloud storage once an ASPI was captured using a smartphone camera, and then each image was processed through a digital image processing approach in a processing platform. Three important steps, namely, pre-processing, image segmentation and qualitative assessment, are involved in the processing platform of the mobile screening framework. The ASPIs are pre-processed to minimise or eliminate any unwanted areas within the image. Then, these ASPIs are segmented through multi-thresholding Otsu approach with clustering number n = 3. Segmentation result shows that the accuracy of the proposed method is 87.5%, which is comparable with the previously established work that has applied three-step differencing (3SD) method. However, the proposed approach has better computational time which is six times faster than the 3SD method. These results demonstrate a remarkable effort to produce a simple but straightforward digital image processing approach to be implemented in cloud computing for future studies.

The theory and practice of real-estate valuation has attracted immense interest over the past decades. This paper is concerned with the sales comparison approach. First, a brief survey of some procedures used worldwide, the sales comparison by adjustments, the hedonic regression and the hedonic price index method, is presented. To improve the versatility of property appraisals a new valuation method, as a combination of multi-objective optimization (MOO) and multi-criteria decision analysis (MCDA) is developed. A unique feature of this model is that it enables the appraiser to evaluate the characteristics of a property on those scales of measurement to which they belong de facto. To comply with this objective, distinct metric distance functions on each scale of measurement, including the two qualitative scales (nominal and ordinal), are employed. After that, the physical worth of a property is derived as a weighted sum of the composite scores. This can be measured on an interval scale. To predict the monetary worth of a property, a simple linear regression model is developed. The benefits of the use of this multi-attribute valuation method is also discussed. A comprehensive real-world study showing the application of the procedure is included.

Computer Science and Graph Theory provide instructive tools for the study and graphical interpretation of these networks. In this paper, we examine the 26/11 Mumbai attack terrorist network dataset and employ the Preference Ranking Organization Method for Enrichment of Evaluation (PROMETHEE) for identification of key node on the terrorist network. PROMETHEE is an effective multi-criteria decision-making model. It provides a framework to find the most suitable alternative by integrating the quantitative and qualitative factors to the decision problem and facilitates easy computation. From the 26/11 Mumbai attacks data set of terrorist network. It is found that out of several terrorists in the network “Wassi” was the focal actor. Based on the PROMETHEE framework, it is resolved that the obtained terrorist nodes can be instrumental for the intelligence and law enforcement agencies to confine their focus on important members of the terrorist network which can deter the functioning of these networks.

Development studies have got both discourse as well as empirical field of research. This paper presents a synthesis of research methodology and its philosophical settings in the field. It deals with philosophical and methodological approaches from the qualitative research design approach. Then it offers a methodological plural perspective along with the discussion of interpretivism, criticalism and social constructivism. Though this paper is not developed out of an empirical field study, the methodology here employed is the review based reflexive perspective of the author. Discussing the context of grounded theory approach, the paper illustrates how a position of the researcher and the conditionality of the study universe affect each other. The central argument of the paper maintains that in multi-real world the disciplinary approach and single-method inquiry could not go into the depth of the research world. Rather, the realties are complex and often changing rapidly in the given political economic context of development. It is thus a time to look after the methodological approach of development studies.

Abstract. A multi-label classification concept is introduced for the mineral mapping task in drill-core hyperspectral data analysis. As opposed to traditional classification methods, this approach has the advantage of considering the different mineral mixtures present in each pixel. For the multi-label classification, the well-known Classifier Chain method (CC) is implemented using the Random Forest (RF) algorithm as the base classifier. High-resolution mineralogical data obtained from Scanning Electron Microscopy (SEM) instrument equipped with the Mineral Liberation Analysis (MLA) software are used for generating the training data set. The drill-core hyperspectral data used in this paper cover the visible-near infrared (VNIR) and the short-wave infrared (SWIR) range of the electromagnetic spectrum. The quantitative and qualitative analysis of the obtained results shows that the multi-label classification approach provides meaningful and descriptive mineral maps and outperforms the single-label RF classification for the mineral mapping task.

The role of container logistics centre as home bases for merchandise transportation has become increasingly important. The container carriers need to select a suitable centre location of transshipment port to meet the requirements of container shipping logistics. In the light of this, the main purpose of this paper is to develop a fuzzy multi-criteria decision-making (MCDM) model to evaluate the best selection of transshipment ports for container carriers. At first, some concepts and methods used to develop the proposed model are briefly introduced. The performance values of quantitative and qualitative subcriteria are discussed to evaluate the fuzzy ratings. Then, the ideal and anti-ideal concepts and the modified distance measure method are used in the proposed model. Finally, a step-by-step example is illustrated to study the computational process of the quantitative and qualitative fuzzy MCDM model. The proposed approach has successfully accomplished our goal. In addition, the proposed fuzzy MCDM model can be empirically employed to select the best location of transshipment port for container carriers in the future study.

Medical reasoning describes a form of qualitative inquiry that examines the cognitive (thought) processes involved in making medical decision. In this field the goal for diagnostic reasoning is assessing causes of observed conditions in order to make informed choices about treatment. In order to design a diagnostic reasoning method we merge ideas from a hypothetic-deductive method and the Domino model. In this setting, we introduce the so called Hypothetic-Deductive-Domino (HD-D) algorithm. In addition, a multi-agent approach is presented, which takes advantage of the HD-D algorithm for illuminating different standpoints in a diagnostic reasoning and assessment process, and for reaching a well-founded conclusion. This multi-agent approach is based on the so called Observer and Validating agents. The Observer agents are supported by a deductive inference process and the Validating agents are supported by an abductive inference process. The knowledge bases of these agents are captured by a class of possibilistic logic programs. Hence, these agents are able to deal with qualitative information. The approach is illustrated by a real scenario from diagnosing dementia diseases.

The Balkan region has an important geostrategic position in passenger and freight transport between Europe and Asia. This paper studies the development of railway transport on twelve different railway transport markets in the Balkan region. The methodology is based on multi-criteria assessment of the level of railway development. The approach presented in this paper could help railway companies to make decisions about railway transport services. The methodology includes three steps. In the first step, the quantitative and qualitative criteria for the evaluation of the social, economic, infrastructural and technological impact of the level of development of railway transport have been defined. In the second step, the weights of criteria have been determined using both objective and subjective approaches by applying the Shannon Entropy method and the Stepwise Weight Assessment Ratio Analysis (SWARA) method. The third step presents the ranking of the countries by applying three multi-criteria methods – VIse Kriterijumska Optimizacija i kompromisno Resenje (VIKOR), Weighted Aggregated Sum Product Assessment (WASPAS) and Preference Ranking Organization Method for Enrichment Evaluation (PROMETHEE), which are different in their approaches. The results show that the criteria: maximum train technical speed (13%), ERTMS Level (10%), number of train kilometres per year (9%) and Ro-La intermodal service (9%) have a great importance in the ranking. It was found that the most developed railway transports in the Balkan region are Turkey, Croatia, Slovenia, and Romania.

The purpose of this article is to propose a fuzzy multi-attribute perfor- mance measurement (MAPM) framework using the merits of both a novel Weighted Aggregated Sum-Product Assessment method with Fuzzy values (WASPAS-F) and Analytical Hierarchy Process (AHP). The object of this study is to select the best shopping centre construction site in Vilnius. A number of conflicting qualitative and quantitative attributes exist for evaluating alternative construction sites. Qualitative attributes are accompanied by ambiguities and vagueness. This makes fuzzy logic a more natural approach to this kind of multi-attribute decision making (MADM) prob- lems. Fuzzy AHP is applied for assigning weights of the attributes and WASPAS-F method is used to determine the most suitable alternative.<br /><br />

Background: Treatment of oral cancer has evolved throughout the past decades which has led to the introduction of the multi-disciplinary team approach (MDT). The MDT concept has been endorsed as the main approach to ensure holistic care for oral cancer patients worldwide. In Malaysia, the MDT concept has been introduced in few hospitals throughout the country. According to the available literature, the MDT approach has improved coordination of care for oral cancer patients, communication between the different disciplines, decision making to obtain the best treatment plan, provided educational opportunities for development of the members, and improved staff and patient well-being. However, little evidence is available to support the fact that the MDT approach has improved patient survival and outcome. Aim: The aim of this study was to explore the MDT approach in the management of oral cancer patients. To our knowledge this is the first study on head and neck MDTs in Malaysia. Methods: The study was conducted at University of Malaya. A mixed-method study was commenced including both quantitative and qualitative designs. The quantitative part assessed the MDT members' attitude toward the role and use of the MDT approach in oral cancer patient management, while the qualitative part assessed the perception of the MDT members regarding the MDT approach in terms of: team structure, team process, decision making, barriers and suggestions for improvement of the MDT approach. The quantitative study was conducted through a structured self-administered questionnaire which were both content and face validated, and distributed to the members of the head and neck MDT. The qualitative study was commenced through two focus group discussions (FGDs) conducted separately. Results: The study was conducted among the head and neck MDT members at University Malaya which received a 100% response rate. The majority of the MDT members showed positive attitudes toward the MDT approach, with the seniors being more positive than the juniors. The MDT approach has improved team dynamics in terms of communication, care coordination and decision making. However, there were a few issues of miscommunication as well as long waiting lists for oncological radiotherapy machines and radiologic scanning. Conclusion: The MDT approach is certainly the preferable mode of care for oral cancer patients in University of Malaya. However, there is a need for further improvement with regards to communication between the team members, expansion of the current team composition, training of the MDT members with regards to clinical and nonclinical skills, guidelines, protocols and certain facilities. Teamwork is a fundamental perspective which is crucial for an effective MDT. As such, a better understanding of each other's roles and responsibilities within the team is essential to ensure optimum patient care and management.
