A two-parameter distributed sensing system for temperature and strain monitoring based on highly nonlinear fiber
Authors: Zhan Yage , Shen Ziyang , Sun Zeyu , Yu Qiao , Liu Hong , Kong Yong 
Published: February 2018

Purpose
The purpose of this paper is to theoretically analyze and experimentally demonstrate the investigation of and present a kind of sensing system for monitoring simultaneous temperature and strain measurements based on highly nonlinear fiber (HNLF) and single mode fiber (SMF).

Design/methodology/approach
First, the stimulated Brillouin scattering (SBS) characteristics of the HNLF have been studied, including the Brillouin gain bandwidth, Brillouin gain center frequency and SBS threshold. Second, based on the Brillouin gain center frequency, the Brillouin frequency shift coefficients of strain and temperature in HNLF have been studied. Third, the sensing and signal interrogation scheme for simultaneous monitoring of temperature and strain with high resolution has been presented.

Findings
It is found that the HNLF has a wider Brillouin gain bandwidth. The SBS threshold of HNLF is 78 mW, which is much larger than 7.9 mW of SMF. Also, the Brillouin frequency shift coefficients of strain and temperature in HNLF are 0.0308 and 0.413 MHz/°C, respectively.

Originality/value
The larger threshold of SBS is useful to avoid SBS under certain situations that Spontaneous Brillouin Scattering is necessary and should be applied. The technique is based on the fact that the Brillouin frequency shift coefficients of strain and temperature in HNLF are different from those in SMF. Therefore, the two-parameter monitoring can be achieved by producing SBS and obtaining the back-scattering Brillouin signal light simultaneously in HNLF and SMF.
Responding to business model innovation: organizational unlearning and firm failure
Authors: Snihur Yuliya 
Published: February 2018

PurposeThis paper aims to examine Borders response to business model innovation (BMI) by Amazon in the bookselling industry. The case illuminates potential causes for protracted periods of organizational unlearning, explaining why organizational unlearning, although beneficial in many documented cases, can also be insufficient to prevent failure.Design/methodology/approachArchival data are used to study Borders’s historical evolution from 1995 to its 2011 bankruptcy. Theoretical inferences are drawn from this case to shed light on the process of organizational unlearning.FindingsBorders failed because its top managers were unable to adjust its traditionalist superstore identity to respond in an adequate manner to the changes in their environment. Instead, the company went through protracted phases of weathering the storm, denial and unlearning, resulting in bankruptcy. This extreme case of failure explains why sometimes, organizational unlearning might be insufficient, resulting in organizational demise rather than renewal.Research limitations/implicationsA longitudinal study of an extreme case allows the author to build links between the research on organizational unlearning and the scholarship on organizational identity.Practical implicationsOrganizations may survive longer if their top managers engage in the process of organizational identity change in response to BMI in their industry. The article proposes a few actions that organizations might usefully take to react to BMI before it is too late.Social implicationsBetter understanding of failure may enable preventive behavior.Originality/valueThis article explains how organizational identity prevents learning the right things and augments the dangers organizations face during unlearning.
Organizational unlearning: time to expand our horizons?
Authors: Becker Karen 
Published: February 2018

PurposeInterest in the topic of unlearning has grown in recent years, fueled by rapid changes in the business environment and resultant organizational change. This change challenges individuals and organizations to unlearn past knowledge and practice to embrace new organizational realities. However, much of the unlearning literature focuses on either individual or organizational factors that enable or hinder unlearning. This paper aims to look beyond the organizational boundary to question whether there are tensions between professionals and the organizations in which they work that influence organizational unlearning.Design/methodology/approachThis is a conceptual paper analyzing how professions are established to identify the implications for organizational unlearning. The critical elements of a profession are explored to identify the potential impact that professionals within the organization may have on organizational learning and unlearning.FindingsThe paper argues that to facilitate unlearning, organizations must recognize not only internal factors but also external pressures on individuals and groups. In particular, professions with a strong identity may represent a significant force that can either engender or resist attempts to learn and unlearn by the organization.Originality/valueWithin the existing unlearning literature, individual and organizational factors that facilitate or hinder unlearning have been widely canvased. However, little attention has been given to the factors beyond organizational boundaries that may also impact unlearning, particularly for individuals and groups with strong professional identities. This paper offers some unique insights into this potential factor for consideration by those seeking to enhance organizational unlearning.
Social comparison, materialism, and compulsive buying based on stimulus-response-model: a comparative study among adolescents and young adults
Authors: Islam Tahir , Sheikh Zaryab , Hameed Zahid , Khan Ikram Ullah , Azam Rauf I. 
Published: February 2018

Purpose
The purpose of this paper is to provide the overview of factors responsible for materialism and compulsive buying among adolescents and young adults. In today’s world, materialism is a crucial phenomenon of the modern age. According to social comparison theory, comparisons are a significant factor affecting the behavioral intentions of adolescents and young adults. Thus, this study develops a framework based on the stimulus–organism–response model and uses the framework to examine the impact of interpersonal communication and marketing factors on social comparison, materialism and compulsive buying, with social media acting as a moderator.

Design/methodology/approach
Using a survey method, data were collected in Study 1 from adolescents (n = 298) and in Study 2 from young adults (n = 345). Structural equation modeling analysis using partial least squares technique was used to analyze the data.

Findings
The results show that social comparison plays a significant role in developing materialistic values and compulsive buying among adolescents and young adults. Through these two studies, it was found that young adults are more socially comparative, materialistic and compulsive in buying as compared to adolescents. Moreover, social media use moderated the relationship between social comparison with peers and media celebrities, which means that rapid increase of social media use leads adolescents and young adults to create high social comparison and materialistic values.

Research limitations/implications
This research is based on the cross-sectional method, which limits the research findings.

Practical implications
This research helps corporate managers understand the interpersonal communication role in creating social comparison among individuals. The study found that peer communication plays a more important role in enhancing the social comparative values among young adults than among adolescents, which provides clear implications for the practitioner.

Originality/value
This study makes a significant contribution to extant literature by discussing the above issue and presenting quantitative data. The study extends the literature by examining and validating a theoretical model of how interpersonal communication among socializing agents affects social comparison among young adults and adolescents. This research examines outcomes of the social comparison with parents, peers and social media, based on the stimulus–organism–response (SOR) model.
Revising a measure to assess consumer-related family communication patterns
Authors: Krcmar Marina , Lapierre Matthew Allen 
Published: February 2018

Purpose
This paper aims to revise an earlier version of a measure used to assess parent–child consumer-based communication to better capture how parents talk with their children about consumer matters.

Design/methodology/approach
Three separate studies were used to revise the measure. The first tested the original measure with parents and children in a supermarket to determine its predictive validity. The second utilized focus groups with parents to refine the measure. The final study sampled 503 parents via MTurk to test the performance of the revised measure regarding reliability and validity.

Findings
The first study found that the original scale did not perform well as it relates to predicting child consumer behavior. The second study used parents to describe in their own words how they talk to their own children about consumer issues. Using these insights, the final study used the redesigned scale and identified four dimensions to the consumer-related family communication patterns instrument: collaborative communication, control communication, product value and commercial truth. These four dimensions had good reliability, convergent validity and predictive validity.

Research limitations/implications
With an updated measure of parent–child consumer-based communication that more closely matches how parents talk to their children about consumer issues, this measure can help researchers understand how children are socialized as consumers.

Originality/value
This study offers researchers a reliable and valid measure of parent–child consumer-based communication that can help inform future studies on this important topic.
Becoming at home in residential care for older people: a material culture perspective
Authors: Lovatt Melanie 
Published: February 2018

AbstractResidential homes encourage new residents to bring belongings with them, so that they can personalise their room and ‘feel at home’. Existing literature on material culture in residential homes views objects as symbols and repositories of home and identity, which can facilitate a sense of belonging in residents through their display in residents' rooms. I suggest that this both misunderstands the processual and fluid nature of home and identity, and conceptualises objects as essentially passive. This article uses ethnographic data and theories of practice and relationality to argue that rather than the meaning of home being inherent in objects, or felt subjectively by residents, meaning is generated through ongoing, everyday interactions between the two. I show that residents became at home by acquiring new things –as well as displaying existing possessions – and also through interacting with mundane objects in everyday social and relational practices such as cleaning and hosting. I conclude that being at home in older people's residential homes need not be so different from being at home at other stages of the life course and in other settings. This challenges conceptualisations of older people's homes – and older age itself – as somehow unknowable and unfamiliar.
Thinking with care infrastructures: people, devices and the home in home blood pressure monitoring
Authors: Weiner Kate , Will Catherine 
Published: February 2018

AbstractThe growing consumer market in health monitoring devices means that technologies that were once the preserve of the clinic are moving into spaces such as homes and workplaces. We consider how one such device, blood pressure monitors, comes to be integrated into everyday life. We pursue the concept of ‘care infrastructure’, drawing on recent scholarship in STS and medical sociology, to illuminate the work and range of people, things and spaces involved in self‐monitoring. Drawing on a UK study involving observations and interviews with 31 people who have used a consumer blood pressure monitor, we apply the concept beyond chronic illness, to practices involving consumer devices – and develop a critical account of its value. We conclude that the care infrastructure concept is useful to highlight the socio‐material arrangements involved in self‐monitoring, showing that even for ostensibly personal devices, monitoring may be a shared practice that expresses care for self and for others. The concept also helps draw attention to links between different objects and spaces that are integral to the practice, beyond the device alone. Care infrastructure draws attention to the material, but ensures that analytic attention engages with both material and social elements of practice and their connections.
Private finance initiative hospital architecture: towards a political economy of the Royal Liverpool University Hospital
Authors: Jones Paul 
Published: February 2018

AbstractSociological analysis has done much to illuminate the architectural contexts in which social life takes place. Research on care environments suggests that the built environment should not be understood as a passive backdrop to healthcare, but rather that care is conditioned by the architecture in which it happens. This article argues for the importance of going beyond the hospital walls to include the politics that underwrite the design and construction of hospital buildings. The article assesses the case of the yet‐to‐be‐realised Liverpool Royal University Hospital, and the private finance initiative (PFI) funding that underpins the scheme, which is suggested as a salient ‘external’ context for understanding architecture's role in the provision of healthcare of many kinds for many years to come. PFI has major implications for democratic accountability and local economy, as well as for the architecture of the hospital as a site of care. Critical studies can illuminate these paradoxically visible‐but‐opaque hospital spaces by going beyond that which is immediately empirically evident, so as to reveal the ways in which hospital architecture is conditioned by political and economic forces.
POISONED DEVELOPMENT: ASSESSING CHILDHOOD LEAD EXPOSURE AS A CAUSE OF CRIME IN A BIRTH COHORT FOLLOWED THROUGH ADOLESCENCE
Authors: J. SAMPSON ROBERT , S. WINTER ALIX 
Published: February 2018

AbstractThe consequences of lead exposure for later crime are theoretically compelling, but direct evidence from representative, longitudinal samples is sparse. By capitalizing on an original follow‐up of more than 200 infants from the birth cohort of the Project on Human Development in Chicago Neighborhoods matched to their blood lead levels from around age 3 years, we provide several tests. Through the use of four waves of longitudinal data that include measures of individual development, family background, and structural inequalities in how lead becomes embodied, we assess the hypothesized link between early childhood lead poisoning and both parent‐reported delinquent behavior and official arrest in late adolescence. We also test for mediating developmental processes of impulsivity and anxiety or depression. The results from multiple analytic strategies that make different assumptions reveal a plausibly causal effect of childhood lead exposure on adolescent delinquent behavior but no direct link to arrests. The results underscore lead exposure as a trigger for poisoned development in the early life course and call for greater integration of the environment into theories of individual differences in criminal behavior.
An Investigation of China‐U.S. Bilateral Trade and Exchange Rate Changes Using the Autoregressive Distributed Lag Model
Authors: Hurley Dene T. , Papanikolaou Nikolaos 
Published: February 2018

This paper examines how China's bilateral trade with the U.S. responds to exchange rate changes of the real Chinese yuan against the U.S. dollar using annual data covering the period 1985 to 2014. The short‐run dynamics of the China‐U.S. trade balance vs. the yuan's depreciation is examined through the S‐curve and J‐curve effects, and the long‐run relationship is established using the autoregressive distributed lag model. The paper found evidence of the S‐curve but not of the J‐curve in the short‐run although the J‐curve effect is found to be present in the long‐run. China's bilateral ratio of exports to imports with the U.S. is found to have an inelastic response to the yuan's exchange rate change against the U.S. dollar in the short‐run, but in the long‐run, it has the expected elastic response. Compared with the influence of the Yuan‐U.S. dollar exchange rate change and China's real income, U.S. real GDP has the largest impact on China‐U.S. bilateral trade relations in the long‐run. Additionally, the structural break in the data series in 2008 from the Great Recession had a small but significant short‐term effect on the bilateral trade between the two nations. Following an exchange rate shock, the deviation of China's trade ratio from its long‐run level takes less than 2 years to converge.

AbstractWe provide a molecular study on peripheral populations of three closely related species of African forest‐dependent greenbuls: the generalist Eurillas latirostris and the specialists Phyllastrephus cabanisi and Arizelocichla nigriceps. These species co‐occur within their range limits in the Kenyan Afromontane forest, Cherangani Hills. This forest has experienced drastic deforestation, which began about 50 years ago, that is causing habitat fragmentation. The aims of this study, using the analyses of molecular tools, are twofold: (i) to provide evidence that functional traits (i.e., ecological attributes) may shape different genetic structure in peripheral populations and (ii) to identify the possible effects of forest fragmentation. Blood and plucked feathers were sampled from a total of 124 birds analysed using two molecular approaches: (i) sequencing of cytochrome b mtDNA and (ii) genotyping nuclear DNA at eight microsatellite loci. Molecular diversity indices, minimum spanning network and mismatch distribution analysis of mtDNA results indicated that the peripheral populations showed different demographic trends: a highly variable and bimodal pattern in forest specialist P. cabanisi, a less variable and unimodal pattern in forest generalist E. latirostris and in the montane specialist A. nigriceps. Although this is a pilot study on the Cherangani forest fragmentation, the nuclear results may not exclude the hypothesis of reduced connectivity in all forest‐dependent greenbuls.
Contemporary Oxygenator Design: Shear Stress‐Related Oxygen and Carbon Dioxide Transfer
Authors: Hendrix Rik H. J. , Ganushchak Yuri M. , Weerwind Patrick W. 
Published: February 2018

AbstractDesign of contemporary oxygenators requires better understanding of the influence of hydrodynamic patterns on gas exchange. A decrease in blood path width or an increase in intraoxygenator turbulence for instance, might increase gas transfer efficiency but it will increase shear stress as well. The aim of this clinical study was to examine the association between shear stress and oxygen and carbon dioxide transfer in different contemporary oxygenators during cardiopulmonary bypass (CPB). The effect of additional parameters related to gas transfer efficiency, that is, blood flow, gas flow, sweep gas oxygen fraction (FiO2), hemoglobin concentration, the amount of hemoglobin pumped through the oxygenator per minute—Qhb, and shunt fraction were contemplated as well. Data from 50 adult patients who underwent elective CPB for coronary artery bypass grafting or aortic valve replacement were retrospectively analyzed. Data included five different oxygenator types with an integrated arterial filter. Relationships were determined using Pearson bivariate correlation analysis and scatterplots with LOESS curves. In the Capiox FX25, Fusion, Inspire 8F, Paragon, and Quadrox‐i groups, mean blood flows were 4.8 ± 0.9, 5.3 ± 0.7, 4.9 ± 0.7, 5.0 ± 0.6, and 5.7 ± 0.6 L/min, respectively. The mean O2 transfer/m2 membrane surface area was 44 ± 14, 51 ± 9, 60 ± 10, 63 ± 14, and 77 ± 18, respectively, whereas the mean CO2 transfer/m2 was 26 ± 14, 60 ± 22, 73 ± 29, 74 ± 19, and 96 ± 20, respectively. Associations between oxygen transfer/m2 and shear stress differed per oxygenator, depending on oxygenator design and the level of shear stress (r = 0.249, r = 0.562, r = 0.402, r = 0.465, and r = 0.275 for Capiox FX25, Fusion, Inspire 8F, Paragon, and Quadrox‐i, respectively, P < 0.001 for all). Similar associations were noted between CO2 transfer/m2 and shear stress (r = 0.303, r = 0.439, r = 0.540, r = 0.392, and r = 0.538 for Capiox FX25, Fusion, Inspire 8F, Paragon, and Quadrox‐i, respectively, P < 0.001 for all). In addition, O2 transfer/m2 was strongly correlated with FiO2 (r = 0.633, P < 0.001), blood flow (r = 0.529, P < 0.001), and Qhb (r = 0.589, P < 0.001). CO2 transfer/m2 in contrast was predominately correlated to sweep gas flow (r = 0.567, P < 0.001). The design‐dependent relationship between shear stress and gas transfer revealed that every oxygenator has an optimal range of blood flow and thus shear stress at which gas transfer is most efficient. Gas transfer is further affected by factors influencing the O2 or CO2 concentration gradient between the blood and the gas compartment.

Published: February 2018

AbstractIn vitro biocompatibility assessments that consider physiologically appropriate conditions of cell exposure to peritoneal dialysis fluids (PDFs) are still awaited. In this study, we found that fragmentation of Golgi apparatus occurred in a pH‐dependent manner within 30‐min exposure to five distinct commercially available PDFs, which showed no marked difference in their effects on cell viability in the conventional MTT assay. Fluorescence microscopy analysis of labeling antibody against cis‐Golgi protein GM130 indicated that the stacked cisternal structure was maintained in the perinuclear area of both M199 culture medium and a neutral‐pH PDF groups. However, this specific structure became partially disassembled over time even in a neutral‐pH PDF, and fragmentation was markedly enhanced in cells exposed to neutralized‐pH PDFs in correspondence with their intracellular pH; moreover, in acidic PDFs, Golgi staining was diffuse and scattered in the entire cytoplasm and showed partial aggregation. The Golgi fragmentation markedly observed with the neutralized PDFs could be reversed by replacing either the media with a neutral‐pH medium or a mixture of PDF and PD effluent (PDF) in a gradient manner mimicking clinical conditions. Furthermore, although weaker than pH effect, notable effects of other PDF‐related factors were also observed after 30‐min exposure to pH‐adjusted PDFs. Lastly, the results of studies conducted using MAPK/SAPK inhibitors indicated that the mechanism underlying the Golgi fragmentation described here differs from that associated with the fragmentation that occurs at the G2/M checkpoint in the cell cycle. We conclude that Golgi fragmentation is suitable for rapid biocompatibility assessment of PDF not only because of its strong pH dependence but also because the fragmentation is recognizably affected by PDF constituents.
