Purpose
The development of wearable technology has significantly changed the way people participate in physical activities. The purpose of this paper is to segment users of sports wearable devices based on technology readiness (TR).

Design/methodology/approach
Participants comprised a convenience sample of 356 participants using sports wearable devices in South Korea. Cluster analysis was performed to identify clusters of sports wearable users based on their TR (i.e. motivating and inhibiting beliefs regarding technologies). Analysis of variance and post hoc Tukey’s test were used to determine whether there were significant differences among the clusters.

Findings
Clustering identified three groups of users of sports wearable devices: Explorers (high motivation, low inhibition), Laggards (low motivation, high inhibition) and Pioneers (high motivation, high inhibition). Each group demonstrated significant differences in TR (i.e. optimism, innovativeness, discomfort and insecurity). It also found that Laggards are more likely to be female and older users (i.e. over 40 years old).

Originality/value
This study explores characteristics of possible market segments and provides a better understanding of user profiles of sports wearable devices. These findings provide insightful implications for marketers of sports wearable devices, who can tailor marketing strategies to each segment. Designers of sports wearable devices can benefit from the user profiles and develop more appropriate products for users.

SummaryOne carbon (C1) metabolism plays an important role in marine carbon cycling but the dynamics and modes of C1 transformations are not fully understood. We made contemporaneous measurements of methylamine and methanol metabolism to elucidate the role of C1 compounds as sources of carbon, energy and nitrogen. Methanol and methylamine were predominantly used as an energy source in offshore waters (oxidation rate constant: kmethanol: 0.02−0.10 day−1; kmethylamine: 0.01−0.18 day−1), but were also important sources of biomass carbon in coastal waters (assimilation rate constant: kmethanol: 0.04−0.10 day−1; kmethylamine: 0.01−0.05 day−1). The relative extent of assimilation versus oxidation for these substrates correlated positively with chlorophyll, nutrients and heterotrophic bacterial production. Methanol oxidation and assimilation were stimulated significantly by nutrient addition. In contrast, methylamine metabolism was inhibited by ammonium or nitrate, suggesting that methylamine served as a nitrogen source. A preliminary metagenomic survey revealed a diverse population of putative C1‐utilizing microorganisms. These results show that the remineralization of methylamine could provide both C and N sources for microbes. Both methanol and methylamine contribute to microbial energetic and carbon substrate demands with a distinctly different signature in nearshore versus offshore environments.
Foreign Direct Investment in China's High‐technology Manufacturing Industries
Authors: Lovely Mary E. , Huang Zixuan 
Published: September 2018

AbstractThis paper provides a survey of foreign investment activity in China's high‐technology manufacturing industry. In addition, we closely examine the relationship between industrial policy, foreign investment and China's high‐technology export success using the development of an indigenous integrated circuits industry as a case study. This paper finds that China's efforts to raise the productivity and innovative capacity of indigenous enterprises is consistent with rising domestic shares of high‐technology assets and profits. Nevertheless, foreign‐funded enterprises remain the source of most high‐technology manufactured exports, primarily from wholly foreign‐owned firms. In sum, despite indigenous development, Chinese high‐technology manufacturing and exports remain deeply tied to foreign investment.

Published: September 2018

AbstractThiamethoxam (TMX) is one of the most effective neonicotinoid insecticides for the control of green peach aphid, Myzus persicae (Sulzer) (Hemiptera: Aphididae), and various side effects can be expected in its natural enemies. The multicolored Asian lady beetle or harlequin ladybird, Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae), is an important predator against M. persicae in greenhouses and fields. In this study, we evaluated the toxicity of TMX to H. axyridis and the effect on the functional response of this predator to M. persicae through three routes of exposure. Acute toxicity bioassays indicated that LC50 values of TMX on H. axyridis through direct residual contact (‘contact’), systemic application (‘systemic’), and leaf‐dip treatment (‘leaf‐dip’) were 18.99, 21.26, and 15.39 mg a.i. l−1, respectively. The hazard quotient indicated a potential hazard of this agrochemical regardless of the exposure routes. The mortality caused by the lowest rate, 2 mg a.i. l−1, was not significantly different compared with the control group. For the three routes of sublethal TMX exposure, the type‐II functional response was a good fit to the prey consumption of H. axyridis. Predation was most affected by leaf‐dip treatment, followed by contact and systemic treatments, which had similar effect. For all exposure routes, the predation capacity of the predator recovered quickly after transfer to untreated cabbage leaves. Thiamethoxam applied systemically was the least toxic to H. axyridis and did not affect the functional response of the predator. However, the sublethal effects of TMX through both contact and leaf‐dip application may reduce the population growth of H. axyridis and consequently impair the biological control of M. persicae by this predator. These results illustrate that the assessment of potential effects of TMX on H. axyridis is crucial to develop effective integrated pest management programs for M. persicae in China.
Quantifying invader impact: Applying functional response metrics to a rapidly spreading non‐native species

Abstract

Risk assessment currently lacks pliable tools that can be reliably applied across a range of environmental contexts to predict the success and impact of non‐native species (NNS). An approach adopting functional responses (FR) and the Relative Impact Potential (RIP) metric may offer considerable insight and predictive power regarding invader impacts, which may include losses in ecosystem function and biodiversity. We aim to evaluate the use of FRs and the RIP metric in predicting impact in non‐native, data‐deficient bivalves.

Very little is known about the potential impacts of the Gulf wedge clam, Rangia cuneata outside of its native range, and as a rapidly spreading non‐native species, it is highly suitable for this study. Comparisons of feeding activity and abundance between non‐native species and functionally analogous native species may produce reliable impact predictions where significant disparity in these factors exists. We conducted field abundance surveys and laboratory feeding studies on R. cuneata, in order to quantify FRs and the RIP metric. Clearance rates and FRs were calculated for R. cuneata and the sympatric, native unionid duck mussel, Anodonta anatina, across a range of algal concentrations at 1.0 ppt salinity.

Mean ± SE clearance rates (ml g DW−1 hr−1) were found to be significantly greater for R. cuneata (294.31 ± 65.17) than for A. anatina (125.99 ± 29.59) with both species exhibiting a type I functional response. As a result of far greater field abundance of R. cuneata compared with A. anatina (37.7 m−2 ± 6.1 versus 0.7 m−2 ± 0.4 at sympatric sites) and a significantly higher feeding rate, the RIP score for R. cuneata was high (11.61) signifying likely ecological impact. Calculating the probability density function for the RIP includes uncertainty in the metric and also yielded a very high value (38.14), and these results provide the first evidence that R. cuneata should be considered a high‐risk invasive species.

The results of our analyses firmly support the assertion that R. cuneata will likely continue to have significant impact in its introduced range if management action is not taken. The rate of spread of R. cuneata, its established densities and RIP score are all comparable to severely invasive bivalves; therefore, R. cuneata may pose a significant threat to both freshwater and brackish water biodiversity and function. We conclude that FRs and the RIP metric may be extremely beneficial to making reliable impact predictions for non‐native species and are particularly well suited for estimating the potential impacts of data‐deficient novel and emerging non‐natives.
Does size matter? Particle size vs. quality in bivalve suspension feeding

Published: September 2018

Abstract

Increases in total suspended solids (TSS) in rivers have likely contributed to the decline in unionid mussel population sizes as feeding and reproduction are reduced at high TSS concentrations. Surprisingly, however, unionids are often found in turbid rivers. We predicted that clay‐sized particles, which comprise > 80% of river seston (particles in suspension), were too small to affect unionid clearance rate (CR) and thus explain this conundrum.

We examined this hypothesis in laboratory experiments involving four unionid species exposed to four particle‐size based TSS treatments (mixed sediment: 0–63 μm; clay: 0–5 μm; fine silt: 5–38 μm; coarse silt: 38–63 μm; sourced from mussel sites) at 20 mg/L, which is a TSS concentration sufficient to reduce CR.

Whereas the CR for all species was lower for mixed sediment, coarse silt and clay treatments—the latter was opposite to our prediction—the CR of mussels given the fine silt treatment was similar to the no‐TSS control for two species and higher than the other TSS treatments in the other two species. Fine silt contained the most fluorescent (i.e. algal) particles and the highest protein and lipid content, which suggests that CR were higher on the more nutritious diet.

Particle quality, rather than size, is what modulates suspension feeding in turbid rivers. Our current understanding of the ecological effects of bivalve suspension feeding will need to be revised to incorporate field‐based measurements.
Realising platform operational agility through information technology–enabled capabilities: A resource‐interdependence perspective
Authors: Tan Felix Ter Chian , Pan Shan L. , Zuo Meiyun 
Published: September 2018

AbstractIntensifying competition in recent times requires business‐to‐consumer (B2C) e‐commerce platforms to develop operational agility for competitive advantage. Despite the agreement on an increasing competitive landscape, the process for realising information technology (IT)‐driven operational agility on e‐business platforms has received little scrutiny. Through an investigation of M.com, a leading multisided online retailing platform in China, this study provides a clear thesis of resource interdependencies and IT‐enabled capabilities forged during operational processes to realise operational agility. Our investigation, observations, and reflections from practice substantiate a model of how a platform like M.com cultivates IT‐driven resource‐interdependent competencies and capabilities tantamount to realising operational agility. The model shows how IT enables three capabilities—localised, synergistic, and optimised—which reflect the effective co‐ordination of three resource interdependencies (pooled, sequential, and reciprocal) during M.com's complex operations and processes, and explicates the consequences. For research, we postulate that IT‐enabled operational agility in complex organisational forms, cultivated through the development of resource‐interdependent capabilities to deliver effective sensing and response mechanisms, forms effective strategies for the B2C platform in dynamic marketplace conditions.

Published: September 2018

AbstractBackgroundThe associations between an anti‐inflammatory diet and both all‐cause and cause‐specific mortality have been studied previously; however, the influence of an anti‐inflammatory diet on survival time has not been investigated. Moreover, the potential modification of these associations by smoking status remains unclear.ObjectiveThe aims of this study were to examine the associations between an anti‐inflammatory diet index (AIDI) and all‐cause and cause‐specific mortality, to determine the association between the AIDI and differences in survival time and to assess effect modification by smoking status.MethodsThe study population included 68 273 Swedish men and women (aged 45–83 years) at baseline. The anti‐inflammatory potential of the diet was estimated using the validated AIDI, which includes 11 potential anti‐inflammatory and five potential pro‐inflammatory foods. Cox proportional hazards and Laplace regression were used to estimate hazard ratios and differences in survival time.ResultsDuring 16 years of follow‐up (1 057 959 person‐years), 16 088 deaths [5980 due to cardiovascular disease (CVD) and 5252 due to cancer] were recorded. Participants in the highest versus lowest quartile of the AIDI had lower risks of all‐cause (18% reduction, 95% CI: 14–22%), CVD (20%, 95% CI: 14–26%) and cancer (13%, 95% CI: 5–20%) mortality. The strongest inverse associations between the highest and lowest quartiles of AIDI and risk of mortality were observed in current smokers: 31%, 36% and 22% lower risks of all‐cause, CVD and cancer mortality, respectively. The difference in survival time between current smokers in the lowest AIDI quartile and never smokers in the highest quartile was 4.6 years.ConclusionAdherence to a diet with high anti‐inflammatory potential may reduce all‐cause, CVD and cancer mortality and prolong survival time especially amongst smokers.
Work as a Masculinity Contest
Authors: Berdahl Jennifer L. , Cooper Marianne , Glick Peter , Livingston Robert W. , Williams Joan C. 
Published: September 2018

AbstractWe propose that a key reason why the workplace gender revolution has stalled (England, 2010) is that work remains the site of masculinity contests among men. In this article, we outline a theoretical framework for thinking about work as a masculinity contest, beginning with a brief review of scholarship on masculinity and exploring how the workplace is a context in which men feel particular pressure to prove themselves as “real men.” We identify different dimensions of masculinity along which employees may compete and how the competition may differ by work context. We propose that organizations with Masculinity Contest Cultures (MCCs) represent dysfunctional organizational climates (e.g., rife with toxic leadership, bullying, harassment) associated with poor individual outcomes for men as well as women (e.g., burnout, low organizational dedication, lower well‐being). We discuss how papers in this special issue contribute insight into MCCs and end with a discussion of the contributions made by conceptualizing work as a masculinity contest, and directions for future research.

Abstract

Objectives
The human skin microbiota is mainly composed of bacteria belonging to the genera Staphylococcus, Cutibacterium, Micrococcus and Corynebacterium, but on the skin of the face and back, ca. 50% of the total microbiota is represented by the bacterium Cutibacterium acnes. The aim of this research was to evaluate the impact of C. martini EO and its major compound, geraniol, on C. acnes.

Methods
The minimum inhibitory concentration against C. acnes strains, phenotypic changes and responses of the proteome was determined. In addition, was assessed the effect of compounds in RNA-binding assay, on C. acnes-exposed keratinocytes and on the C. acnes type distribution on shoulder skin.

Key findings
The range of the MIC was 0.7 to 1.6 mg/ml for the three main C. acnes types. There were no cytotoxic effects of compounds in the absence or presence of C. acnes; after 7 days of exposure to C. martini EO, we could not detect a major shift of the C. acnes types on shoulder skin that was found to be dominated by C. acnes strains of types II and IA2.

Conclusions
Our work gives novel insight into the skin microbiota-interacting properties of C. martini EO.

ABSTRACTBackground and objectiveInspiratory muscle training (IMT) enhances velocity of inspiratory muscle contraction and modifies inspiratory and expiratory time. This study aimed to examine the impact of high‐intensity IMT (H‐IMT) on exercise capacity in bronchiectasis.MethodsForty‐five patients were included. Lung function, respiratory muscle strength and endurance, exercise capacity, dyspnoea, fatigue and quality of life (QOL) were evaluated. Patients were randomized into two groups: H‐IMT and control groups. Twenty‐three patients underwent H‐IMT for 8 weeks, using threshold loading with a target workload of maximal inspiratory pressure (MIP) of at least 70%, with 3‐min cycles (as 2‐min training: 1‐min rest intervals) for 21 min. There was a total period of 14 min of loaded breathing and 7 min of recovery. The control group (n = 22) underwent low‐intensity IMT at 10% of the initial MIP and was maintained at the same intensity until the end of the training.ResultsAfter training, both MIP and maximal expiratory pressure (MEP) and the incremental shuttle walk distance were increased in the H‐IMT group compared with the control group (P < 0.05). There was a significant difference in constant threshold load, time and pressure–time units in the H‐IMT group (P < 0.05) but not in the control group (P > 0.05). A significant decrease was found in fatigue in both groups (P < 0.05). The Leicester Cough Questionnaire social score for the H‐IMT group decreased significantly after the treatment (P < 0.05).ConclusionThe H‐IMT increased exercise capacity in patients with non‐cystic fibrosis bronchiectasis. It has also positive effects on respiratory muscle strength and endurance, and social aspects of QOL.

Published: September 2018

ObjectivesThe objective of this study was to understand the effect of citizen mobilization on both electoral outcomes and on the likelihood that new candidates will enter races to challenge incumbent politicians.MethodsThis study uses quantitative, longitudinal data (at the congressional‐district level) on protest, electoral outcomes, and challengers entering races, which are analyzed using an autoregressive distributed lagged regression model.ResultsResults show that protests that express liberal issues lead to a greater percentage of the two‐party vote share for Democratic candidates, while protests that espouse conservative issues offer Republican candidates a greater share of the two‐party vote. Additionally, results indicated that protest shines a light on incumbent politicians’ failure to address constituent concerns, which leads quality candidates to enter subsequent races to challenge incumbent politicians.ConclusionsCitizen activism, which has been shown to impact state and firm policy decisions, also impacts electoral outcomes.

AbstractObjectiveTo investigate age‐associated changes of flash visual evoked potentials (FVEPs) in sedated horses.Animal studiedTwenty‐eight clinically healthy Standardbred Warmblooded trotters, aged 36 hours to 28 years.ProceduresLight‐adaptedFVEPs andFERGs were recorded (An‐visionRETIport, Roland‐consult, Germany) in response to flash stimuli. Sedation was obtained using alpha‐2‐agonists intravenously. Akinesia of the eyelids was induced and pupils were dilated.ResultsReproducibleFVEPs andFERGs were readily recorded from all foals and horses. TheFVEPwaveform included up to four positive components (P1‐P5) and two negative components (N1 and N2) andFVEPwaveform morphology was similar across all age groups. Some differences in peak times and amplitudes associated with increasing age were observed.FVEPamplitudes recorded from newborn foals were well above the amplitudes observed in normal adult horses andFVEPpeak times were somewhat shorter. In adult horses, a significant increase in P4 peak time and a gradual decrease in amplitudes, mainly for N2P4, were seen across the life‐span.ConclusionsThe overall equineFVEPwaveform was similar across the normal life‐span of the horse in our cross‐sectional study. We found that the visual system of the foal seems to be well developed already at birth. Furthermore, our results showed a decrease in amplitudes and increase in some peak times with increasing age. We recommend that age‐matched controls should be used when evaluating foals and young horses in clinical practice, whereas horses over the age of three years can be compared to other adult horses.
