State estimation in bioheat transfer: a comparison of particle filter algorithms
Authors: Lamien Bernard , Varon Leonardo A.B. , Orlande Helcio R.B. , Elicabe Guillermo E. 
Published: April 2017

Purpose
The purpose of this paper is to focus on applications related to the hyperthermia treatment of cancer, with heating imposed either by a laser in the near-infrared range or by radiofrequency waves. The particle filter algorithms are compared in terms of computational time and solution accuracy.

Design/methodology/approach
The authors extend the analyses performed in their previous works to compare three different algorithms of the particle filter, as applied to the hyperthermia treatment of cancer. The particle filters examined here are the sampling importance resampling (SIR) algorithm, the auxiliary sampling importance resampling (ASIR) algorithm and Liu & West’s algorithm.

Findings
Liu & West’s algorithm resulted in the largest computational times. On the other hand, this filter was shown to be capable of dealing with very large uncertainties. In fact, besides the uncertainties in the model parameters, Gaussian noises, similar to those used for the SIR and ASIR filters, were added to the evolution models for the application of Liu & West’s filter. For the three filters, the estimated temperatures were in excellent agreement with the exact ones.

Practical implications
This work may help medical doctors in the future to prescribe treatment protocols and also opens the possibility of devising control strategies for the hyperthermia treatment of cancer.

Originality/value
The natural solution to couple the uncertain results from numerical simulations with the measurements that contain uncertainties, aiming at the better prediction of the temperature field of the tissues inside the body, is to formulate the problem in terms of state estimation, as performed in this work.
Retrieving thermal conductivity of the solid sample using reduced order model inverse approach
Authors: Adamczyk Wojciech Piotr , Ostrowski Ziemowit 
Published: April 2017

Purpose
Prompted by the reliability and robustness of the previously proposed method of non-destructive measurement of thermal conductivity (TC) for anisotropic materials, the enhanced approach is presented in this study. The main improvement lies in the substitution of the analytic solution of direct problem solver with a numerical one. This solver, used during the inverse procedure that fits measurement data into simulated ones, is proposed to be a numerical one (finite volume method). Moreover, the purpose of this study is to show the applicability of the reduce order model for retrieving thermal conductivity of solid body.

Design/methodology/approach
In the proposed methodology, both the laser heat source and temperature measurements are performed on the same side of the sample material, which is the main difference with respect to the classic Parker flash method. To speed up the computational time, the full numerical model used in the course of inverse solution is replaced by the proper orthogonal decomposition (POD)-radial basis function (RBF) reduced order model, which is fast and accurate.

Findings
The TCs measured using the proposed methodology are in good agreement with the well established (but destructive) measurement methods. The advantage of the proposed approach lies in the optimal approximation properties of the POD approximation basis used in reduced order model, as well as in its regularization properties.

Practical implications
The proposed technique has high application potential in the design of novel apparatus for non-destructive measurement of TCs for both isotropic and anisotropic materials.

Originality/value
This is the first time when the POD-RBF reduced order model is used in the procedure of non-destructive TC measurement for anisotropic bodies.
The need for a long-term mindset when measuring the effects of lean on health-related quality management values
Authors: Ingelsson Pernilla , Bäckström Ingela 
Published: April 2017

Purpose
The purpose of this paper is to investigate the effects a lean initiative has on the health-related quality management (QM) values, “Leadership Commitment” and “Participation of Everybody,” as well as on perceived co-worker health in the public sector.

Design/methodology/approach
A case study was carried out at a municipal division that had been working with lean for approximately 18 months. A questionnaire was used to measure the effect on health-related QM values both before and after the initial 18 month period. Documents from the intended lean implementation were studied at the starting point and after 18 months; this was followed up by examining new documents. The results from the questionnaires were analyzed using SPSS and the documents were analyzed by means of document comparisons and consensus discussion in the research group.

Findings
The effects on the health-related QM values; “Leadership Commitment” and “Participation of everybody” in this study showed that the values still permeated the organization to a relatively high extent after 18 months but that no statistical differences can be shown between the two measurement points. When measuring what effects a lean initiative has on values, a period of 18 months might be too short, if significance changes are expected. None the less, the results can be a way of monitoring the development of these softer values. Something that is equally important is to see if there have been any major changes, as a way of keeping the work with building a new culture alive and in focus. The results strengthen the assumption that a long-term mindset is needed when QM initiatives such as lean are applied within an organization especially when changes to values and workplaces are expected.

Originality/value
This study has further explored the QM in relation to lean in the respect of how the QM values “Leadership commitment” and “Participation of Everybody” are effected by a lean initiative.
Stock prices, exchange rate and interest rate: evidence beyond symmetry
Authors: Ajaz Taufeeq , Nain Md Zulquar , Kamaiah Bandi , Sharma Naresh Kumar 
Published: April 2017

PurposeThis paper aims to examine the dynamic interactions between monetary and financial variables in the Indian context.Design/methodology/approachIn this paper, the authors have applied a recently developed asymmetric autoregressive distributed lag (ARDL) model by Shinet al.(2014), for detecting nonlinearities focusing on the long-run and short-run asymmetries among economic variables.FindingsThe results point toward the presence of asymmetric reaction of stock prices to changes in interest rate and exchange rate in full sample, as well as in pre-crisis. However, no asymmetry was found in the post-crisis period. The results further suggest that tight monetary policies appear to retard the stock prices, more than easy monetary policies that stimulate them.Practical implicationsThe findings of the study can be helpful in understanding the policy transmission mechanism through asset price channel.Originality/valueTo the best of the authors’ knowledge, this is the first study that examines the interactions between monetary and financial variables in the Indian context in an asymmetric framework. The findings of this study are quite interesting and are different from several existing studies in the literature.
Does public investment crowd-out private investment in India
Authors: Muthu Shanmugam 
Published: April 2017

Purpose
The purpose of this paper is to examine the crowding-in or crowding-out relationship between public and private investment in India.

Design/methodology/approach
The autoregressive distributed lag (ARDL) bounds testing approach is used to estimate the long run relationship between public and private investment using annual data from 1971-1972 to 2009-2010.

Findings
Based on the empirical findings, it is observed that aggregate public investment has a positive effect on private investment both in the long run and the short run. In contrast to the findings of previous studies, no significant impact of public infrastructure investment on private investments is found in the long run, while non-infrastructure investment has a positive impact on private investment in the short run. Among the various categories of infrastructure sector, a positive and significant impact in the case of electricity, gas and water supply is observed. Similarly, the result indicates that public investment in machinery and equipment and construction have substantially influenced the private sector machinery and equipment in the long run and the short run. In the case of the role of macroeconomic uncertainty, the results find a negative and significant impact on private investment and the impact is higher in the short run than in the long run.

Originality/value
The present study extends the literature in three important ways: First, the study attempts to capture heterogeneity of public investment as well as disaggregate effects of two different categories of public infrastructure on private investment. The extent to which two different types of public assets impact the private investment in machinery and equipment investment is also examined. Second, ARDL model is used to examine the long-run relationship between public and private investment. Third, the study incorporates macroeconomic uncertainty into the empirical analysis to examine the role of macroeconomic volatility in determining private investment decision.
Size does matter – span of control in hospitals
Authors: Holm-Petersen Christina , Østergaard Sussanne , Andersen Per Bo Noergaard 
Published: April 2017

Purpose
Centralization, mergers and cost reductions have generally led to increasing levels of span of control (SOC), and thus potentially to lower leadership capacity. The purpose of this paper is to explore how a large SOC impacts hospital staff and their leaders.

Design/methodology/approach
The study is based on a qualitative explorative case study of three large inpatient wards.

Findings
The study finds that the nursing staff and their frontline leaders experience challenges in regard to visibility and role of the leader, e.g., in creating overview, coordination, setting-up clear goals, following up and being in touch. However, large wards also provide flexibility and development possibilities.

Practical implications
The authors discuss the implications of these findings for decision makers in deciding future SOC and for future SOC research.

Originality/value
Only few studies have qualitatively explored the consequences of large SOC in hospitals.
Leadership quality: a factor important for social capital in healthcare organizations
Authors: Strömgren Marcus , Eriksson Andrea , Ahlstrom Linda , Bergman David Kristofer , Dellve Lotta 
Published: April 2017

PurposeThe purpose of this paper is to investigate the relation between leadership and social capital and what qualities of leadership are important for social capital among employees in hospital settings over time.Design/methodology/approachA cohort of employees in hospitals answered a questionnaire at three occasions. Five small (approx. 100-bed) or mid-sized (approx. 500-bed) hospitals were included. The response rate was 54 percent at baseline (n=865), 59 percent at one-year follow-up (n=908) and 67 percent at two-year follow-up (n=632).FindingsRepeated measures over time showed differences between groups in levels of social capital with respect to levels of leadership quality. Relation-oriented leadership had the strongest association with social capital. There was evidence that leadership was associated with social capital over time and that different kinds of leadership qualities were associated with social capital.Research limitations/implicationsThis study conducted and analyzed quantitative data, and therefore, there is no knowledge of managers’ or employees’ own perceptions in this study. However, it would be interesting to compare managers’ decreased and increased leadership quality and how such differences affect social capital over time.Practical implicationsThe findings feature the possibility for healthcare leaders to build high quality leadership as an important resource for social capital, by using different leadership orientations under different circumstances.Originality/valueThe paper showed that leadership was an important factor for building social capital and that different leadership qualities have different importance with respect to certain circumstances.
The effect of marketing communication on business relationship loyalty
Authors: Hänninen Nora , Karjaluoto Heikki 
Published: April 2017

Purpose
The purpose of this paper is to create a new understanding of industrial business-to-business (B2B) relationships by connecting the theoretical streams of marketing communications and relationship marketing. This study tests how various marketing communication channels and communication quality increase the transformation of customer-perceived value into customer loyalty.

Design/methodology/approach
The theoretical framework consists of links between customer-perceived value, marketing communication quality, channel effectiveness, and customer loyalty. The age of the business relationship is also taken into consideration. Empirical testing is based on global survey data (n=121) collected from customers of Finnish manufacturing companies operating in the paper, mineral, and metal-processing industries.

Findings
The effects of customer-perceived value on customer loyalty are both direct and indirect, as marketing communications partially mediate this relationship. The customer-perceived effectiveness of various marketing communication channels adds more to loyalty formation than the perceived quality of marketing communications.

Practical implications
Of special interest for marketing practitioners is the channel-specific approach to the effectiveness of marketing communications. Results suggest that personalized channels would be the most important mediators of the effects of perceived value on loyalty and also bring up the possibility of combining personalized direct communication with new cost-effective digital channels.

Originality/value
Relatively little research has examined the mediating role of marketing communications in the relationship between perceived value and loyalty in the B2B context.
Investigating consumer advocacy, community usefulness, and brand avoidance
Authors: Jayasimha K.R. , Chaudhary Harish , Chauhan Anurag 
Published: April 2017

Purpose
The purpose of this paper is to examine the behavioral outcomes and effectiveness of organizational response to open complaints by consumers following a dissatisfactory service experience.

Design/methodology/approach
Three natural communities (WhatsApp groups) were used with reference to online food and grocery retailing. The respondents comprised community members sharing negative experiences on the group. A scenario implanted in a survey was used as the research approach.

Findings
Consumer advocacy, a form of complaining, is a way to help other community members. The relationship between consumer advocacy and community usefulness strengthens the argument of consumers’ collective concern as one of the motivational frames for consumer advocacy. Consumer advocates show stronger reactions, resulting in brand avoidance following voice complaining. An effective organizational response can mitigate brand avoidance.

Practical implications
Finding ways to restrict and alleviate brand avoidance is an area that is of major interest to practitioners. The study finds that prospective explanations could be a very effective antidote to brand avoidance.

Originality/value
The social side of complaining is a relatively under-researched area. This study examines the relationship between consumer advocacy, community usefulness and brand avoidance. To the best of the authors’ knowledge, this is the first study to examine the moderating effect of organizational response on consumer advocacy and its outcomes in the virtual context.
Examining the dilution of the consumer-brand relationship on Facebook: the saturation issue
Authors: Ramadan Zahy 
Published: April 2017

Purpose
Brands have been progressively using social networking sites, namely, Facebook, as part of their strategy to engage their consumers and ultimately build long-term relationships with them. Nonetheless, with the overuse of “engagement ads” by brands, saturation related to information overload is expected to be reached leading to the dilution of the consumer–brand relationship. The purpose of this paper is to fill a gap in the literature which has predominantly focused on the positive side of social networking sites, and hence still lacks a thorough understanding of the potential risks brands face when using Facebook. Accordingly, this research examines the different risks brands would be facing from saturated consumers on social networking sites such as Facebook.

Design/methodology/approach
A qualitative study was conducted, with a total of 40 respondents using face-to-face semi-structured interviews over two stages. While the first stage of the study focused on examining the saturation risk and its potential negative effects, the second one explored these risks specifically on the consumer–brand relationship on Facebook. The interviews were recorded, transcribed and then coded for analysis using NVivo 8.

Findings
Brands are overloading their followers with passively endorsed brand messages, which are negatively affecting consumers’ experience on Facebook, as well as the relationship with these brands. This overall dilution of the consumer–brand relationship on Facebook was hence found to be affecting interaction, similarity with friends, the system quality of the social networking site, as well as information quality. Furthermore, this dilution was found to be affecting brand likability, brand trust and brand association.

Originality/value
The negative implications are still scarcely examined in the literature where social media engagement is predominantly discussed through a positive lens. Hence, this study has the peculiarity of discussing the risks that companies would face with Facebook’s engagement model along with their implications on the consumer-brand relationship.

Authors: Gaus Nurdiana 
Published: April 2017

Purpose
The purpose of this paper is to show the research process which is laid on the interrelated aspects of paradigm-research-based approaches and research designs.

Design/methodology/approach
It draws on my PhD research project experience, where I deployed these interrelated aspects informing my methodological perspective to produce quality research via the generation of legitimate research findings.

Findings
From this practice, my chosen held paradigm, constructionism, has guided me to proceed with my research process, leading to the selection of a research approach (qualitative case study) and research designs (interviews, observation, and document analysis).

Originality/value
This conduct helps valorise the legitimacy of my research findings to produce legitimate knowledge. This reflective account of the research process can become a lesson for others who wish to go through a legitimate process of selecting the research approaches and research designs, particularly, in social sciences.
Ethnographic research with young people: methods and rapport
Authors: Tickle Sarah 
Published: April 2017

PurposeThis paper accounts for, and reflects upon, the research design and the methodological approach adopted in ethnographic research with young people. In particular, the purpose of this paper is to reinforce the significance of conducting qualitative participatory and innovative methods with young people, alongside the value of rapport building.Design/methodology/approachQualitative participatory methods are understood as the most appropriate way to empower and respect young people in the research process. Alongside such methods the ethnographic nature of the research is discussed in conveying the importance of rapport building with young people in the field. In doing so the paper examines a number of important considerations when conducting youth research.FindingsThe triangulation of qualitative methods was fundamental in exploring and understanding young people’s lives in each locality and allowed for deep and meaningful explorations of specific themes. The additional and complementary methods employed alongside traditional methods were particularly suited to understanding young people’s everyday lives, as complex experiences are not always conveyed through traditional methods alone. Conducting participatory methods produced narratives around safety, security and governance in public places.Originality/valueBeing reflexive and adapting to a research setting in order to enhance the process of building and maintaining trust with young people is the most important facet when conducting youth research. Giving careful consideration to the impact of a researcher’s presence in the field needs to be carefully navigated.
The role of triangulation in sensitive art-based research with children
Authors: Vanner Catherine , Kimani Mary 
Published: April 2017

Purpose
The purpose of this paper is to highlight the critical role of triangulation to create authentic analytical frameworks amidst contradictory participant narratives in sensitive art-based research (ABR) with children.

Design/methodology/approach
Multiple qualitative case study research included three months of participant observation, individual semi-structured teacher interviews and open-ended art-based interviews using the Draw-Write-Narrate method (Ogina and Nieuwenhuis, 2010) with upper primary students in two schools in Kirinyaga County, Kenya.

Findings
The art-based approach to student interviews, combined with participant observation and teacher interviews, provided a child-centred process that illuminated students’ understandings and experiences while minimizing risks to participants. Its application requires researchers to recognize data collection and analysis as subjective processes that strongly benefit from triangulation to interpret a diversity of perspectives that may not easily align.

Originality/value
As ABR with children increases in popularity, it is important to identify challenges in the process of analysis and meaning-making. This paper identifies triangulation as a valuable tool for handling the challenge of diverse perspectives from child participants, particularly in conducting sensitive research that may increase the likelihood of contradictory narratives.
Rapid G0/1 transition and cell cycle progression in CD8+ T cells compared to CD4+ T cells following in vitro stimulation
Authors: Mishima Takuya , Fukaya Shotaro , Toda Shoko , Ando Yoshiaki , Matsunaga Tsukasa , Inobe Manabu 
Published: April 2017

ABSTRACTT‐cell population consists of two major subsets, CD4+ T cells and CD8+ T cells, which can be distinguished by the expression of CD4 or CD8 molecules, respectively. Although they play quite different roles in the immune system, many of their basic cellular processes such as proliferation following stimulation are presumably common. In this study, we have carefully analyzed time–course of G0/1 transition as well as cell cycle progression in the two subsets of quiescent T‐cell population following in vitro growth stimulation. We found that CD8+ T cells promote G0/1 transition more rapidly and drive their cell cycle progression faster compared to CD4+ T cells. In addition, expression of CD25 and effects of its blockade revealed that IL‐2 is implicated in the rapid progression, but not the earlier G0/1 transition, of CD8+ T cells.
