Acoustic Cue Weighting by Adults with Cochlear Implants: A Mismatch Negativity Study
Authors: Moberly Aaron C. , Bhat Jyoti , Shahin Antoine J. 
Published: December 2015

Objectives:
Formant rise time (FRT) and amplitude rise time (ART) are acoustic cues that inform phonetic identity. FRT represents the rate of transition of the formant(s) to a steady state, while ART represents the rate at which the sound reaches its peak amplitude. Normal-hearing (NH) native English speakers weight FRT more than ART during the perceptual labeling of the /ba/–/wa/ contrast. This weighting strategy is reflected neurophysiologically in the magnitude of the mismatch negativity (MMN)—MMN is larger during the FRT than the ART distinction. The present study examined the neurophysiological basis of acoustic cue weighting in adult cochlear implant (CI) listeners using the MMN design. It was hypothesized that individuals with CIs who weight ART more in behavioral labeling (ART users) would show larger MMNs during the ART than the FRT contrast, and the opposite would be seen for FRT users.

Design:
Electroencephalography was recorded while 20 adults with CIs listened passively to combinations of 3 synthetic speech stimuli: a /ba/ with /ba/-like FRT and ART; a /wa/ with /wa/-like FRT and ART; and a /ba/wa stimulus with /ba/-like FRT and /wa/-like ART. The MMN response was elicited during the FRT contrast by having participants passively listen to a train of /wa/ stimuli interrupted occasionally by /ba/wa stimuli, and vice versa. For the ART contrast, the same procedure was implemented using the /ba/ and /ba/wa stimuli.

Results:
Both ART and FRT users with CIs elicited MMNs that were equal in magnitudes during FRT and ART contrasts, with the exception that FRT users exhibited MMNs for ART and FRT contrasts that were temporally segregated. That is, their MMNs occurred significantly earlier during the ART contrast (~100 msec following sound onset) than during the FRT contrast (~200 msec). In contrast, the MMNs for ART users of both contrasts occurred later and were not significantly separable in time (~230 msec). Interestingly, this temporal segregation observed in FRT users is consistent with the MMN behavior in NH listeners.

Conclusions:
Results suggest that listeners with CIs who learn to classify phonemes based on formant dynamics, consistent with NH listeners, develop a strategy similar to NH listeners, in which the organization of the amplitude and spectral representations of phonemes in auditory memory are temporally segregated.
The Equilibration of Pco 2 in Pigs Is Independent of Lung Injury and Hemodynamics
Authors: Buehler Sarah , Lozano-Zahonero Sara , Wirth Steffen , Runck Hanna , Gamerdinger Katharina , Förster Katharina , Haberstroh Jörg , Guttmann Josef , Schumann Stefan 
Published: December 2015

Objectives:
In mechanical ventilation, normoventilation in terms of Pco
2 can be achieved by titration of the respiratory rate and/or tidal volume. Although a linear relationship has been found between changes in respiratory rate and resulting changes in end-tidal co
2 (△Petco
2) as well as between changes in respiratory rate and equilibration time (t
eq) for mechanically ventilated patients without lung injury, it is unclear whether a similar relationship holds for acute lung injury or altered hemodynamics.

Design:
We performed a prospective randomized controlled animal study of the change in Petco
2 with changes in respiratory rate in a lung-healthy, lung-injury, lung-healthy + altered hemodynamics, and lung-injury + altered hemodynamics pig model.

Setting:
University research laboratory.

Subjects:
Twenty mechanically ventilated pigs.

Interventions:
Moderate lung injury was induced by injection of oleic acid in 10 randomly assigned pigs, and after the first round of measurements, cardiac output was increased by approximately 30% by constant administration of noradrenalin in both groups.

Measurements and Main Results:
We systematically increased and decreased changes in respiratory rate according to a set protocol: +2, -4, +6, -8, +10, -12, +14 breaths/min and awaited equilibration of Petco2. We found a linear relationship between changes in respiratory rate and △Petco
2 as well as between changes in respiratory rate and t
eq. A two-sample t test resulted in no significant differences between the lung injury and healthy control group before or after hemodynamic intervention. Furthermore, exponential extrapolation allowed prediction of the new Petco
2 equilibrium and t
eq after 5.7 ± 5.6 min.

Conclusions:
The transition between Petco
2 equilibria after changes in respiratory rate might not be dependent on moderate lung injury or cardiac output but on the metabolic production or capacity of co
2 stores. Linear relationships previously found for lung-healthy patients and early prediction of Petco
2 equilibration could therefore also be used for the titration of respiratory rate on the Petco
2 for a wider range of pathologies by the physician or an automated ventilation system.
Early Results From the Implementation of a Lung Cancer Screening Program
Authors: Lanni Thomas B. , Stevens Craig , Farah Michael , Boyer Andrew , Davis James , Welsh Robert , Keena Daniel , Akhtar Adil , Mezwa Duane 
Published: December 2015

Purpose:
In 2010, a new study published by the National Lung Screening Trial showed a 20% reduction in mortality for those patients screened with low-dose computed topography (CT) versus x-ray. Recently, the Centers of Medicare and Medicaid have agreed to cover this service for those patients who meet the screening criteria. We compare the outcomes and costs associated with developing and implementing a lung cancer screening program.

Materials and Methods:
One thousand sixty-five patients were screened from January 2014 to December 2014. These patients were screened on a low-dose CT screening protocol throughout Beaumont Health System. The American College of Radiology Lung Imaging Reporting and Data System (Lung-RADS) were used to assign the score for each patient. Screening eligibility criteria were based on the National Comprehensive Cancer Network guidelines. Downstream activity and revenue was determined after initial low-dose CT screening.

Results:
At 1 year, 20 patients (1.6%) were diagnosed with lung cancer and another 15 patients were diagnosed with another form of cancer after screening. The median age, packs per day, and pack years smoked for all patients was 63, 1.0, and 39.0 years, respectively. Lung-RADS scores for all patients was 18% (1), 24.1% (2), 6.3% (3), and 5.4% (4). The net revenue for all activity after screening was $3.2 million.

Conclusions:
The establishment of a low-dose CT lung cancer screening program improved the ability to screen patients as demonstrated by the number of patients screened and those diagnosed with a malignancy. These findings were also consistent with the findings from the National Lung Screening Trial study.

Authors: Scheick Stacey M. , Morris Christopher G. , Amdur Robert J. , Bova Frank J. , Friedman William A. , Mendenhall William M. 
Published: December 2015

Objectives
To determine the long-term outcome after stereotactic radiosurgery (SRS) for temporal bone paragangliomas.

Materials and Methods:
We retrospectively reviewed the medical records of 11 patients with temporal bone paragangliomas (10 patients with a glomus jugulare tumor and 1 patient with a glomus tympanicum tumor) treated between January 1997 and July 2012 at the University of Florida with SRS to a median dose of 15 Gy in 1 fraction. Ten previously unirradiated patients received SRS as did 1 patient who received prior fractionated radiotherapy (FRT) and then received salvage SRS for a local recurrence. The major outcome endpoint was local control, meaning no further growth or shrinkage on follow-up computed tomography or magnetic resonance imaging scans.

Results:
The median follow-up time was 5.3 years. Two patients developed a local recurrence after SRS, including the patient who received salvage SRS after prior FRT. The overall local control rates at 5 and 10 years were both 81%. The cause-specific survival rates at 5 and 10 years were both 88%. The distant metastasis-free survival rates at 5 and 10 years were both 100%. The overall survival rates at 5 and 10 years were both 78%. There were no severe complications.

Conclusions:
SRS for benign head and neck paragangliomas is a safe and efficacious treatment associated with minimal morbidity. SRS is suitable for patients with skull base tumors <3 cm when FRT is logistically unsuitable. Surgery is reserved for patients in good health whose risk of associated morbidity is low. Observation is a reasonable option for asymptomatic patients with a limited life expectancy.
Low estimates – high stakes: underestimation of costs at the front-end of projects
Authors: Andersen Bjorn , Samset Knut , Welde Morten 
Published: December 2015

Purpose– The purpose of this paper is to adopt an in-depth perspective on cost estimation, from the development of the initial idea until the budget is agreed, to obtain new insights into issues of underestimation at the front-end.Design/methodology/approach– The study uses a small sample of projects with exceptional increases in cost estimates during the front-end phase. The authors analyzed the magnitude of cost increases and possible reasons for them.Findings– The paper concludes that underestimation in the front-end phase was significant in the sample and poses a serious problem in that suboptimal projects are approved. The causes of underestimation include underestimating risk, overestimating opportunities, inadequate estimation methods and skills, reliance on weak information, and strategic/deliberate scope creep and division of projects.Research limitations/implications– The study builds on a small sample, and hence further studies should be undertaken to verify whether the findings are generalizable.Practical implications– The sample shows that the projects with the most unrealistic early estimates have disputable relevance. The paper suggests a number of recommendations that might help to counter the problem of unrealistic early cost estimates, which in turn, might allow suboptimal projects to be funded.Originality/value– The underestimation of costs at the front-end is grossly neglected in the literature compared with whether costs comply with the budget. While cost overruns are an indication of failure in terms of the project’s tactical performance, the contention is that the up-front underestimation of costs might result in an inferior project being selected and thus affect the strategic performance of the project.
Why local governments rarely use PPPs in their road development projects
Authors: Janssen Rick , Graaf Robin de , Smit Marnix , Voordijk Hans 
Published: December 2015

Purpose– The purpose of this paper is to identify barriers that prevent local governments from applying PPPs in their road development projects.Design/methodology/approach– Based on insights from a literature review, interviews were held with relevant staff to identify barriers. These were verified and their relative significance was determined through the use of a questionnaire, before being reflected upon and compared with literature findings.Findings– The research identified 37 barriers to local governments using PPPs in road development projects and showed that four barriers consistently stand out. First, the application of PPPs requires local governments to adapt their current working methods, which amounts to a large impediment to local governments applying PPPs. Second, local government employees believe that applying PPPs might effectively exclude local contractors from involvement in projects. Finally, local governments experience the whole PPP approach (the third barrier) and the PPP contract (the fourth) as overly complicated.Practical implications– To increase the use of PPPs for infrastructure provision at the local level, one has to focus on removing dominant local barriers as identified in this research.Originality/value– Although local-level PPPs have seen increasing interest, this is one of the first studies paying attention to the barriers to using PPPs for local road development projects.
Communication barriers in an interorganizational ERP-project
Authors: Andersson Annika 
Published: December 2015

Purpose– The purpose of this paper is to explore and analyze communication patterns and bridging activities to be able to describe communication barriers in an interorganizational enterprise resource planning (ERP) project and some ways to overcome those.Design/methodology/approach– The empirical arena was an interorganizational ERP-project, which implemented an On-Premise ERP-system. The goal for the team, assembled from both the buyer and supplier, was to implement an ERP-system, with a fixed price calculated from the expected resources and time needed, half a year. Participant observations, complementary interviews and documentation studies were accomplished, to be able to find and describe communication barriers for organizational development.Findings– Communication barriers were found, such as technnological concerns, micro-level discussions, limited bridging activities and openness to change.Research limitations/implications– The present study, concerning one single, interorganizational ERP-project provides a starting point for further research concerning communication barriers in ERP-projects. Further research could look at the implications communication barriers could have for the buyer and supplier organization in a long term.Practical implications– In managerial implications, some ways to overcome those barriers are discussed.Originality/value– Communication barriers found, and their impact on knowledge development within interorganizational ERP-projects, is described. The paper offers a starting point for future research concerning communication barriers. Results could be used of managers to understand communication barriers and their implications for knowledge development and organizational change.
Procurement strategy formation: (re-)designing rail infrastructure project alliances
Authors: Plantinga Henrico , Dorée André 
Published: December 2015

Purpose– The purpose of this paper is to provide insights into the reasoning behind the development of new procurement approaches by public sector clients.Design/methodology/approach– A case study approach focuses on a procurement development process by a public sector client. It investigates the reasoning behind various applications of the project alliancing concept in rail infrastructure projects over a period of 15 years. Alliancing applications are singled out and mapped against a number of criteria derived from literature on alliancing. The reasoning behind these applications and their differences are reconstructed from contextual documentation. Theories and concepts from the fields of strategic management and knowledge management literature are used to analyse the results.Findings– The development process seems to be evolutionary rather than deliberately planned. The uncovered variations in alliancing applications can only to a very limited extent be explained by the reconstructed reasoning. This suggests that the applied designs are mostly based on implicit reasoning by individual project teams. From a strategic management perspective, the development pattern resembles the emergent type of strategy formation.Originality/value– This study offers an initial insight into the reasoning processes behind the (re-)design of procurement approaches within a public sector client organization. A unique feature of this study is that these reasoning processes are explored from the strategy formation perspective that conceptually links the design of new procurement approaches to strategic management theory.
Antecedents of team turnover intentions in temporary organizations
Authors: Nuhn Helge F.R. , Wald Andreas 
Published: December 2015

Purpose– The purpose of this paper is to shed light on the antecedents of team turnover intentions in temporary organizations such as projects, programs, or temporary teams.Design/methodology/approach– The authors systematically combine the findings from the literature on the antecedents of turnover intentions in permanent organizations (PO) with the characteristics of temporary organizations (TO) and develop a research model comprising personal factors, job-related factors, and organization-related factors.Findings– A research model consisting of testable propositions that the authors derived from both specificities of TO and the antecedents of turnover intentions in PO.Originality/value– The authors contribute to literature by identifying potential antecedents of turnover intentions that are specific to TOs and those that also exist in POs but are adapted to a temporary context. The research model allows future empirical research on turnover in TO to be conducted in a systematic way and supports the development of theory.
Benefits and risks associated with time choice of innovating in retail settings
Authors: Pantano Eleonora 
Published: December 2015

Purpose
– The innovation success requires a deep understanding of risks and benefits of the process, as well as of the best moment for innovating. The purpose of this paper is to explore the current retailers’ choice of innovating in terms of being the first innovator imitating competitors’ innovations, by declining the benefits and risks associated with the both strategies.

Design/methodology/approach
– Building on qualitative data from retail industry, with emphasis on fashion (including clothes, jewelry, and accessories), the investigation provides an empirical contribution to the emerging area on innovation management in retailing through its in-depth investigation of the strategies of eight case retailers who introduced technological innovations in the last three years, and by mapping the patterns between strategy and outcomes.

Findings
– The analysis revealed how pioneers and followers acted their strategies for achieving benefits and reducing the encountered risks. In particular, findings identify to what extend pioneers act according the technology push and followers according to the demand pull.

Originality/value
– The research starts from the definition of the time choice of innovating, and the subsequent choice of being the first innovation adopter or the imitator. The insights support scholarly exploration of innovation management by offering a new marketing management perspective, and providing practitioners with a better understanding on the time choice for innovating in retailing and also in broader empirical settings.
The role of salespeople in developing life insurance customer loyalty
Authors: Yu Tsu-Wei , Tseng Lu-Ming 
Published: December 2015

Purpose
– The purpose of this paper is to closely investigate the antecedents affecting relationship quality and its consequences between life insurers and their customers.

Design/methodology/approach
– Data were collected from the customers of life insurers’ customer relationship management centres and were analysed using in-depth interviews and questionnaires. A structural equation modelling approach is employed to test the hypotheses.

Findings
– The findings are generally consistent with the literature. This study supports all hypotheses. Finally, the findings of this study confirm that relationship quality mediates the effects of salesperson characteristics and relational selling behaviour on customer loyalty.

Originality/value
– To the authors knowledge, there is little published research that examines antecedents and consequences of relationship quality in life insurance industry in Taiwan. Therefore, in addition to developing high-quality services, life insurers need to establish and maintain long-term relationships with customers in order to create corporate innovation value.
The cross-shopping behaviour: patterns of store format mobility in the apparel sector
Authors: Luceri Beatrice , Latusi Sabrina 
Published: December 2015

Purpose– The study investigates the cross-format shopping behaviour in the apparel sector. The purpose of this paper is to relate the number of store formats patronized to a set of consumer characteristics under a unifying theoretical framework emphasising cost-benefit analysis.Design/methodology/approach– The research involved questionnaire telephone surveys from a sample of 1,722 apparel shoppers in a European region.Findings– Among shoppers’ socio-demographic characteristics, age, gender, employment status and citizenship were found to have an impact on multi-store format patronage patterns for apparel purchases. Moreover, the store format preference and the sale proneness proved to be additional determinants of cross-format mobility.Practical implications– The findings provide retail managers with valuable insights for effective marketing strategies aimed to exploit customer loyalty potential.Originality/value– Despite consumers’ regular use of various alternative store formats for apparel purchases, literature on the determinants of cross-format mobility is scarce. Addressing the inter-type cross-shopping behaviour of consumers from a cost-benefit viewpoint, this study makes a new contribution in the area of customer loyalty and the complementarity and substitutability of store formats.
Public library managers’ descriptions of political attention
Authors: Michnik Katarina 
Published: December 2015

Purpose– Public library issues are often described as being of low political priority. Yet circumstances differ for different communities; public library issues may receive varying political attention. The purpose of this paper is to study how Swedish public library managers describe local politicians’ attention to public library issues and to identify which municipal circumstances, such as political organization, population, and finances, seem to matter for how local politicians’ attention is described.Design/methodology/approach– The empirical data were collected through a web-based questionnaire sent to all public library managers in Sweden. To identify the described political attention, a content analysis was done. A multinominal logistic regression analysis was performed to analyze the municipal circumstances that seem to matter for how political attention is described.Findings– A small majority of public library managers described the local political attention as strong or quite strong. Three factors seem to matter for how the attention is described: political organization, existence of a library plan, and population size. In the discussion personal factors, such as the politicians’ personal interest and public library managers’ experience, are brought up as possibly being of considerable importance.Originality/value– Several studies have been conducted on how politicians perceive public libraries; in these studies, the politicians are mainly treated as a unified group. This paper shows that the political approach to public library issues is described as different in different municipal circumstances.
