Individuals’ preference for multiple media use – underlying motives
Authors: Robinson Helen R. 
Published: August 2017

Purpose
The purpose of this paper is to uncover the underlying motives for individuals’ polychronicity, the preference to multitask with media.

Design/methodology/approach
For this exploratory study, a qualitative research design is chosen, using face-to-face in-depth interviews and triad groups. In total, 34 in-depth interviews are conducted in the UK, Germany and Australia, with four subsequent triads in the UK.

Findings
The underlying motives for individuals’ preference for multiple media use include eight dimensions: comfort with multitasking; multi-channel preference; effectiveness and efficiency; convenience; emotional gratification; information and knowledge; social benefits and assimilation.

Research limitations/implications
A non-probability sample of a specific sample group (Digital Natives) is used in this study and despite the reassurance provided by quality criteria and triangulation, generalisation from this study is problematic. Future research to validate the eight exposed dimensions would be valuable.

Practical implications
For marketing communications and media channel planners, endeavouring to optimise clients’ budgets, the unique knowledge provided by the depth of understanding offered by the eight dimensions of polychronicity and their associated facets enables the development of relevant communication campaigns.

Originality/value
This paper presents a unique insight into individuals’ preference for multiple media use, uncovering the underlying dimensions of this behavioural phenomenon. Accordingly, this study makes a valuable contribution to knowledge in this emerging research domain.

Published: August 2017

Purpose
This study aimed to understand young children’s influence on family consumer behavior by examining children's and parents’ points of view in the Brazilian context.

Design/methodology/approach
Through an exploratory approach, the study used focus group discussions and in-depth interviews. Specifically, to elicit children’s perceptions, two focus groups were conducted, and to capture the perspective of the parents, 8 families, via 12 participants, were interviewed.

Findings
Children’s use of information provided by the media in their attempts to influence family decisions is perceived positively by parents because such behavior helps parents to fulfill their parental duties.

Research implications
This study examines how young children perceive their influential role in family consumer decisions and how parents perceive this influence, given the existence of child adultization and adult infantilization.

Originality/value
The findings extend the discussions regarding the adultization of children and the infantilization of adults, revealing positive aspects of such a trend in association with consumer behavior.

Published: August 2017

BackgroundResults from epidemiological studies about the association between maternal prepregnancy obesity and the risk of shoulder dystocia are inconsistent.ObjectiveTo evaluate the effect of maternal prepregnancy obesity on the risk of shoulder dystocia.Search strategyWe searched PubMed and the Web of Science database for all relevant studies up to 5 August 2016 and reviewed the reference lists of identified articles.Selection criteriaObservational studies that investigated the association between prepregnancy obesity and the risk of shoulder dystocia were included.Data collection and analysisA total of 20 articles involving 2 153 898 participants were included in this meta‐analysis. A random‐effects model was used to calculate the pooled relative risks (RRs) with 95% CIs.Main resultsFor obese versus nonobese, the pooled RR of shoulder dystocia was 1.63 (95% CI: 1.33–1.99). The findings remained significant in the cohort studies (RR = 1.57, 95% CI: 1.28–1.93) and case–control studies (RR = 2.70, 95% CI: 1.46–4.98). With regard to the subgroup ‘continents’, there was a significant association between obesity and the risk of shoulder dystocia in Europe (RR = 1.51, 95% CI: 1.18–1.92) and Asia (RR = 2.59, 95% CI: 1.15–5.83). The result from the sensitivity analysis for studies adjusted for gestational diabetes was significant (RR = 1.61, 95% CI: 1.05–2.47). The pooled RRs for obesity classes I, II and III versus nonobese were 1.29 (95% CI: 1.06–1.57), 1.94 (95% CI: 1.26–2.98) and 2.47 (95% CI: 1.56–3.93), respectively.ConclusionThis meta‐analysis suggests that maternal prepregnancy obesity is associated with an increased risk of shoulder dystocia.Tweetable abstractA meta‐analysis shows that maternal prepregnancy obesity increases the risk of shoulder dystocia.
Left Ventricular Aneurysm: Sudden Unexpected Deaths in a 29‐Year‐Old Man
Authors: Srettabunjong Supawon 
Published: August 2017

AbstractLeft ventricular aneurysm (LVA) is an abnormal dilated heart structure, either congenital or acquired. LVA is a rare cardiac condition with no symptoms in most cases, thus occasionally diagnosed during investigations of other diseases. Its association with certain cardiac complications and sudden cardiac deaths has been reported. However, its role as a cause of sudden unexpected death is rare. The author reported a sudden cardiac death in a 29‐year‐old man with LVA. Without a significant coronary artery disease and known etiologies of LVA, such an abnormal heart structure in the present case was considered congenital LVA. As no other possible mechanisms of death could be identified other than LVA with its associated pathologic lesions, mural thrombi, and dilated cardiomegaly, his death was attributable to fatal cardiac arrhythmia (most commonly ventricular tachycardia) secondary to LVA.

BackgroundEffect of anaesthesia and surgery on cell‐free DNA (cfDNA) is not known. Given that surgical stress augments inflammation and injury, we hypothesized that levels of cfDNA will fluctuate during perioperative period. Therefore, in this study serial perioperative cfDNA concentration was measured in donors and recipients undergoing living donor liver transplantation (LDLT).MethodsBaseline, post‐induction, intraoperative and post‐operative plasma cfDNA levels were evaluated in 21 donors and recipients each, by Sytox green method. In addition, qPCR was performed in a subset of samples.ResultsBaseline cfDNA levels were higher in recipients (37.62 ng/ml) than in donors (25.49 ng/ml). A decrease in cfDNA was observed following anaesthesia induction in both recipients (11.90 ng/ml) and donors (10.75 ng/ml). When the kinetics of the cfDNA was monitored further, an increase was noted intraoperatively in donors (46.18 ng/ml) and recipients (anhepatic phase: 56.25 ng/ml, reperfusion phase: 54.36 ng/ml). cfDNA levels remained high post‐operatively. One recipient who developed post‐operative sepsis had the highest cfDNA level (94.72 ng/ml).ConclusionPlasma cfDNA levels are high in recipients indicative of liver injury. Lower cfDNA levels following induction may be attributed to the subduing effect of anaesthetic agents on cell death. High cfDNA levels seen in intra‐ and post‐operative phases reflect cellular trauma and inflammation. This similar pattern of fluctuation of cfDNA level in donors and recipients is suggestive of its possible utility as a surgical stress marker. In addition, comparable cfDNA levels in anhepatic and reperfusion phase reflect less ischemia reperfusion injury during LDLT.

SummaryReduced neurogenesis in the aging mammalian hippocampus has been linked to cognitive deficits and increased risk of dementia. We utilized postmortem human hippocampal tissue from 26 subjects aged 18–88 years to investigate changes in expression of six genes representing different stages of neurogenesis across the healthy adult lifespan. Progressive and significant decreases in mRNA levels of the proliferation marker Ki67 (MKI67) and the immature neuronal marker doublecortin (DCX) were found in the healthy human hippocampus over the lifespan. In contrast, expression of genes for the stem cell marker glial fibrillary acidic protein delta and the neuronal progenitor marker eomesodermin was unchanged with age. These data are consistent with a persistence of the hippocampal stem cell population with age. Age‐associated expression of the proliferation and immature neuron markers MKI67 and DCX, respectively, was unrelated, suggesting that neurogenesis‐associated processes are independently altered at these points in the development from stem cell to neuron. These data are the first to demonstrate normal age‐related decreases at specific stages of adult human hippocampal neurogenesis.

AbstractAimInflammatory breast cancer (IBC) is the most aggressive form of locally advanced breast cancer. The signs of inflammation such as hyperemia and hyperthermia might suggest the possible participation of inflammatory mediators. This study investigates stromal and tumor expression of nuclear factor‐kappa B (NF‐κB) and interleukin‐18 (IL‐18) in samples obtained from IBC and noninflammatory locally advanced breast cancer (LABC) and the influence of these markers on patients' prognosis.MethodsDemographic data, tumor molecular characteristics and overall survival in both groups were also assessed. Furthermore, in this study, we evaluated the expression of IL‐18 and p50 nuclear fraction of NF‐κB by immunohistochemistry in specimens from IBC and LABC (T4b).ResultsWe observed that 24.6% of women were diagnosed with IBC up to age 40. In addition, the patients with IBC showed a lower overall survival when compared to LABC. In regard to molecular markers, ER+, C‐erbB2− or triple negative IBC patients showed a significantly reduced overall survival. In addition, a higher IL‐18 immunostaining in stroma of IBC and LABC was observed in comparison with tumor cells, but stromal immunoexpression was similar between IBC and LABC. Besides, IL‐18 positivity seemed be related with a better clinical response to neoadjuvant chemotherapy. However, NF‐κB expression was identical in both groups.ConclusionThe IL‐18 is present in tumor stroma of IBC and LABC and seems to be associated with the complete response to neoadjuvant chemotherapy.

Background and PurposeCarbon monoxide (CO), a gaseous mediator produced by haem oxygenases (HOs), has been shown to prevent stress‐, ethanol‐, aspirin‐ and alendronate‐induced gastric damage; however, its role in gastric ulcer healing has not been fully elucidated. We investigated whether CO released from tricarbonyldichlororuthenium (II) dimer (CORM‐2) can affect gastric ulcer healing and determined the mechanisms involved in this healing action.Experimental ApproachGastric ulcers were induced in Wistar rats by serosal application of acetic acid. Animals received 9 days of treatment with RuCl3 [2.5 mg·kg−1 intragastrically (i.g.)], haemin (5 mg·kg−1 i.g.), CORM‐2 (0.1–10 mg·kg−1 i.g.) administered alone or with zinc protoporphyrin IX (ZnPP, 10 mg·kg−1 i.g.), 1H‐[1,2,4]oxadiazolo[4,3‐a]quinoxalin‐1‐one (ODQ, 5 mg·kg−1 i.g.), NG‐nitro‐l‐arginine (l‐NNA, 15 mg·kg−1 i.g.), indomethacin (5 mg·kg−1 i.g.) or glibenclamide (10 mg·kg−1 i.g.). Gastric ulcer area and gastric blood flow (GBF) were assessed planimetrically, microscopically and by laser flowmeter respectively. Gastric mRNA/protein expressions of EGF, EGF receptors, VEGFA, HOs, nuclear factor (erythroid‐derived 2)‐like 2 (Nrf2), COX‐2, hypoxia‐inducible factor (HIF)‐1α and pro‐inflammatory iNOS, IL‐1β and TNF‐α were determined by real‐time PCR or Western blots.Key ResultsCORM‐2 and haemin but not RuCl3 or ZnPP decreased ulcer size while increasing GBF. These effects were reduced by ODQ, indomethacin, l‐NNA and glibenclamide. CORM‐2 significantly decreased the expression of pro‐inflammatory markers, Nrf2/HO1 and HIF‐1α, and up‐regulated EGF.Conclusions and ImplicationsCO released from CORM‐2 or endogenously produced by the HO1/Nrf2 pathway accelerates gastric ulcer healing via an increase in GBF, an up‐regulation in EGF expression and down‐regulation of the inflammatory response.
Drinking trajectories of at‐risk groups: Does the theory of the collectivity of drinking apply?
Authors: Norström Thor , Raninen Jonas 
Published: August 2017

AbstractIntroduction and AimsAlcohol consumption among Swedish adolescents has halved during the last decade. We aim to: (i) investigate whether the overall decrease in drinking may conceal an underlying heterogeneity in drinking trajectories across at‐risk groups that differ with respect to risk for drinking and; (ii) assess to what degree alcohol‐related harm has responded to this decrease.Design and MethodsData were obtained from the nationally representative annual school survey of alcohol and drug habits among Swedish ninth‐grade students covering the period 2000–2012 (n ≈ 5000/year). Respondents were divided into five at‐risk groups ranging from low to high based on their relative ranking on a risk scale for drinking. Alcohol consumption was measured by beverage‐specific quantity and frequency items summarised into a measure of overall drinking in litres of 100% alcohol per year. Alcohol‐related harm was measured by eight items asking about whether the respondent had experienced various alcohol‐related negative consequences.ResultsDrinking and alcohol‐related harm decreased in all five at‐risk groups. There was a marked relation between the overall consumption and the mean consumption in each of the five at‐risk groups. Self‐reported alcohol‐related harm decreased during the study period to an extent that was expected from the decrease in alcohol consumption.Discussion and ConclusionsAlcohol consumption among Swedish youth has declined in five groups that were delineated based on their relative ranking on a risk factor index. The findings are consistent with Skog's theory of the collectivity of drinking behaviour. [Norström T, Raninen J.

Reconstruction of money supply over the long run: the case of England, 1270–1870
Authors: Palma Nuno 
Published: August 2017

AbstractThis article provides a time series of coin and money supply estimates for six hundred years of English history. Two main estimation methods are proposed. The first (the direct method) is used to measure the value of government‐provided, legal‐tender coin supply only. Two varieties of the direct method are proposed. Additionally, an indirect method is proposed which relies on a combination of information about nominal GDP with an assumption regarding the evolution of velocity in time, and which can be used to calculate coin supply and M2. Both methods rely on benchmark values known for certain years, but no particular benchmark is determinant for the results. The new methodologies set out here may serve as a blueprint for a similar reconstruction of coin and money supply series for other economies for which analogous data are available.
Recreational fisheries in Portofino Marine Protected Area, Italy: Some implications for the management

Published: August 2017

AbstractSince the 1970s, recreational fishing has become a mass hobby in Italy, reaching a large number of people, who, using modern equipment, increased their harvesting capacity, provoking serious conflicts with the professional fisheries. Recreational fishing is strictly regulated inside Italian Marine Protected Areas (MPAs) and is generally allocated to local residents, mainly to reduce the tensions caused by limitations of access to the resources. The aim of this study was to provide an analysis of recreational fishing activities within the Portofino MPA (Mediterranean Sea), to assess the possible impact on the local fish stocks and to plan potential management actions. Furthermore, some serious inconsistencies on the minimum lengths of fish caught as defined by law relative to the minimum size of first reproduction are discussed. Since 2014, all anglers exploiting the Portofino MPA have been obliged to fill out a logbook. The compilation of these was not completely satisfactory, when compared with a group of reliable anglers whose catches were accurately monitored, but allowed for estimated yields of about 24 kg/angler/yr. After 15 years of protection, the fish biomass has increased within the Portofino MPA, generating a positive spillover effect. At the same time, it has attracted many anglers whose gross harvesting was estimated at about 8 t/year, representing about the 8% of the total yield of the local small‐scale fishery.
“This illness diminishes me. What it does is like theft”: A qualitative meta‐synthesis of people's experiences of living with asthma

Published: August 2017

AbstractBackgroundWhat matters to people in their everyday experiences of living with asthma is influenced by a diverse range of personal, social, medical and environmental factors. Previous reviews of the asthma literature have largely focused on medical aspects of asthma or specific population groups with particular needs.ObjectiveTo identify, describe and synthesize from the available qualitative literature the views and experiences of adults living with asthma.MethodWe systematically searched for qualitative studies reporting on the personal experience of living with asthma. A meta‐synthesis approach was used to analyse and interpret the data. Key themes relating to personal perspectives on asthma were identified and grouped into overarching concepts.ResultsWe identified 26 studies. There was a paucity of literature on the physical burden of asthma symptoms and the role of social support. Our synthesis generated a central concept of the “work” associated with living with asthma: work was of a personal nature, and at times an intensely emotional experience. Individuals tailored their behaviour in response to demands of the physical and social environment, including interactions with health‐care professionals.ConclusionThis is the first systematic review of the qualitative literature reporting on people's own perspectives of living with asthma. Our findings draw attention to the nuances and sensitivities surrounding patient experiences of self‐management. Medical care is a central plank of managing chronic conditions, but our health‐care systems are now expected to deliver patient‐centred care. Considering the broader aspects of asthma management, beyond that of symptoms and treatment, will help to facilitate comprehensive care.

Published: August 2017

AbstractA novel double ceramic layered (DCL) CaZrO3/Yttria‐stabilized zirconia (YSZ) thermal barrier coatings (TBCs) was designed for improved service life against sulfate vanadate hot corrosion as compared with that of YSZ single layered coating. The hot corrosion behavior of DCL CaZrO3/YSZ coatings was studied at 950°C after dry spreading 50%Na2SO4+50%V2O5 mixture onto a coated surface. The CaZrO3 as the topmost layer in DCL CaZrO3/YSZ coatings, served as a sacrificial layer during sulfate vanadate hot corrosion protecting the underneath YSZ coating. The corrosion reactions in this case were sluggish due to the initial formation of low melting point meta‐calcium vanadate (CaV2O6) that isothermally transformed to higher melting point calcium vanadates having higher calcia (CaO) content. The corrosion reaction products sealed the top surface, impeding the oxygen movement and eventually retarded the thermally grown oxide (TGO) growth. The sulfate vanadate hot corrosion life of the DCL CaZrO3/YSZ coatings was observed to be more than double as compared with single ceramic layered YSZ coatings.
Retirement date effects on saving behavior: Endogenous labor supply and non‐separable preferences
Authors: Romm Aylit Tina 
Published: August 2017

AbstractThis paper analyzes the effect of changing retirement dates on pre‐retirement saving, looking at the effect of a negative cross derivative of the utility function with respect to consumption and leisure. This effect is analyzed in the contexts of both exogenous and endogenous labor supply before retirement. In the case of exogenous labor supply, the relative decrease in saving in response to an increase in the expected retirement age is larger in the case of a negative cross derivative of the utility function (non‐separable preferences) than in the case of a zero cross derivative (separable preferences). However, in the case where labor supply before retirement decreases at the intensive margin in response to an increase in the retirement age, the relative decrease in saving in response to an increase in the expected retirement age is smaller in the case of a negative cross derivative than in the case of a zero cross derivative.
