Making Santorini: reflecting on the past, imagining the future
Authors: Lichrou Maria , O’Malley Lisa , Patterson Maurice 
Published: April 2017

PurposeStrategic analyses of Mediterranean destinations have well documented the impacts of mass tourism, including high levels of seasonality and landscape degradation as a result of the “anarchic” nature of tourism development in these destinations. The lack of a strategic framework is widely recognised in academic and popular discourse. What is often missing, however, is local voice and attention to the local particularities that have shaped the course of tourism development in these places. Focusing on narratives of people living and working in Santorini, Greece, this paper aims to examine tourism development as a particular cultural experience of development.Design/methodology/approachThe authors conducted narrative interviews with 22 local residents and entrepreneurs. Participants belonged to different occupational sectors and age groups. These are supplemented with secondary data, consisting of books, guides, documentaries and online news articles on Santorini.FindingsThe analysis and interpretation by the authors identify remembered, experienced and imagined phases of tourism development, which we label as romancing tourism, disenchantment and reimagining tourism.Research limitations/implicationsProfessionalisation has certainly allowed the improvement of quality standards, but in transforming hosts into service providers, a distance and objectivity is created that results in a loss of authenticity. Authenticity is not just about what the tourists seek but also about what a place is or can be, and the “sense of place” that residents have and use in their everyday lives.Social implicationsLocal narratives offer insights into the particularities of tourism development and the varied, contested and dynamic meanings of places. Place narratives can therefore be a useful tool in developing a reflexive and participative place-making process.Originality/valueThe study serves the understanding of how tourism, subject to the global-local relations, is a particular experience of development that shapes a place’s identity. The case of Santorini shows how place-making involves changing, multilayered desires and contradictory visions of tourism and development. This makes socio-cultural and environmental challenges hard to resolve. It is thus challenging to change the course of development, as various actors at the local level and beyond have diverse interests and interpretations of what is desirable for the place.
How does household debt affect financial asset holdings? Evidence from euro area countries
Authors: Kukk Merike 
Published: April 2017

PurposeThe paper aims to investigate the impact of financial liabilities on households’ holdings of financial assets. The debt-to-income ratio of the household sector increased from 75 per cent in 2000 to 99 per cent in 2010 in the euro area on average, and the rapid accumulation of household debt has induced the need to study how indebtedness affects the behaviour of households beyond their borrowing decisions.Design/methodology/approachThe paper uses the first wave of the Household Finance and Consumption Survey from 2009-2010 covering euro area countries. The paper estimates a system of equations for households’ financial liabilities and assets, taking account of endogeneity and selection bias.FindingsThe results indicate that higher household liabilities are related to lower holdings of financial assets. The results are confirmed by a large number of robustness tests. The findings support the hypothesis that credit availability reduces precautionary savings as income shocks can be smoothed by borrowing, meaning fewer assets are held for self-insurance against consumption risk.Practical implicationsThe results are obtained from a recession period when households faced aggregate shocks, whereas credit constraints were tighter than during good times. The implications of lower incentives to keep financial assets by indebted households is that they are actually more vulnerable to aggregate shocks, as they have fewer resources available when they are hit by a negative shock.Originality/valueThis is the first paper to investigate the effect of liabilities on financial assets using household level data. The paper takes a holistic view and models financial assets and liabilities jointly while controlling for endogeneity and selection bias.

SummaryPrey switching occurs when a generalist predator kills disproportionately more of an abundant prey species and correspondingly spares a rarer species. Although this behaviour is a classic stabilizing mechanism in food web models, little is known about its operation in free‐living systems which often include dangerous prey species that resist predation.We used long‐term (1995–2015) data from a large mammal system in northern Yellowstone National Park,USA, to understand how prey preference of a wild, generalist predator (Canis lupus) responds to a shift in prey species evenness involving rising numbers of dangerous prey (Bison bison) and dropping numbers of relatively safer prey (Cervus elaphus).Contrary to the prey switching hypothesis, wolves attacked and killed disproportionately more of the rarer, but safer, species. Wolves maintained a strong preference against bison even when this species was nearly twice as abundant as elk. [Correction added after online publication on 26 April 2017: ‘more than’ changed to ‘nearly’]. There was also evidence that wolves were increasingly averse to hunting bison as relative bison abundance increased.Wolves seldom hunted bison because capture success was limited to a narrow set of conditions: larger packs (>11 wolves) chasing smaller herds (10–20 bison) with calves. Wolves scavenged bison carrion instead and did so more frequently as bison abundance increased.Our study demonstrates the overarching importance of prey vulnerability to understanding the prey preferences of generalist predators in ecological communities with dangerous prey. The formidable defences of such prey diminish the potential for switching and its stabilizing influence on population dynamics. In these communities, shifts from hunting to scavenging are perhaps more likely than shifts in prey preference. The assumption of switching may therefore overestimate the stability of multi‐prey systems that include dangerous prey species.Alay summaryis available for this article.
How rough sea affects marine seismic data and deghosting procedures

Published: April 2017

ABSTRACTMost seismic processing algorithms generally consider the sea surface as a flat reflector. However, acquisition of marine seismic data often takes place in weather conditions where this approximation is inaccurate. The distortion in the seismic wavelet introduced by the rough sea may influence (for example) deghosting results, as deghosting operators are typically recursive and sensitive to the changes in the seismic signal. In this paper, we study the effect of sea surface roughness on conventional (5–160 Hz) and ultra‐high‐resolution (200–3500 Hz) single‐component towed‐streamer data. To this end, we numerically simulate reflections from a rough sea surface using the Kirchhoff approximation. Our modelling demonstrates that for conventional seismic frequency band sea roughness can distort results of standard one‐dimensional and two‐dimensional deterministic deghosting. To mitigate this effect, we introduce regularisation and optimisation based on the minimum‐energy criterion and show that this improves the processing output significantly. Analysis of ultra‐high‐resolution field data in conjunction with modelling shows that even relatively calm sea state (i.e., 15 cm wave height) introduces significant changes in the seismic signal for ultra‐high‐frequency band. These changes in amplitude and arrival time may degrade the results of deghosting. Using the field dataset, we show how the minimum‐energy optimisation of deghosting parameters improves the processing result.

AbstractAimDisease activity assessment in Takayasu arteritis (TA) is challenging. Human leukocyte antigen E (HLA‐E) is shed from endothelium into serum as a soluble molecule (sHLA‐E) in response to inflammation. We aimed to study: (i) utility of sHLA‐E as a biomarker of disease activity; and (ii) association of HLA‐E polymorphism rs1264457 with clinical disease in Asian‐Indian TA patients.Materials and MethodsIn phase‐1, sHLA‐E levels were estimated in sera of 50 consecutive TA patients at baseline visit and 27 healthy controls. Serial estimations were performed in 27 of them. In phase‐2, DNA of 150 TA patients and 264 healthy controls were genotyped for rs1264457 polymorphism.ResultsAt baseline visit, disease was classified as active, stable and grumbling in 23, 18 and nine patients, respectively. sHLA‐E levels were higher in active TA (43; interquartile range [IQR]: 25.3–64.6) pg/mL) than stable disease (12.9; IQR: 7.6–21.6 pg/mL) (P = 0.001). At first follow‐up visit, sHLA‐E levels were numerically higher in active disease than stable disease (P = 0.06) but this trend was blunted at second follow‐up. sHLA‐E levels increased in 54% versus 25% of patients with persistently active/relapsing and persistent stable course, respectively. rs1264457 polymorphism was not associated with susceptibility to TA and did not affect sHLA‐E levels.ConclusionsHLA‐E level is useful as a biomarker of disease activity and course in TA patients. rs1264457 polymorphism is neither associated with susceptibility nor did it influence sHLA‐E levels in TA.
Evaluation of Australian dermatological postoperative patient information leaflets: Should we have a national checklist?
Authors: Hunt William TN , O'Sullivan Niamh‐Anna , Donnelly Alan 
Published: April 2017

AbstractBackground/ObjectivesPatient information leaflets (PILs) are frequently provided to patients following dermatological surgery to provide advice and reassurance in the community. This evaluation reviewed the guidance specified in postoperative PILs across the 40 Australian dermatology teaching departments and clinics.MethodsAll 40 departments and clinics were identified and asked to provide their postoperative information leaflets on sutured wound care (preferable) or excision biopsy (September–October 2015). For eachPIL, 10 preselected parameters were evaluated.ResultsIn total, 28/40 (70%) of units responded. From these units, 11/28 (39.3%) stated they do not use a postoperativePIL. Of the 17 units that provided PILs, the mode minimum dressing duration was 24 (6/17; 35.3%) and 48 h (6/17; 35.3%). For haemostatic advice, 12 PILs specified the time to press on a bleeding wound, with the most common advice being 10 (3/12; 25%) and 20 min (3/12; 25%). Of the 14 PILs that provided analgesic advice, the mode information suggested using paracetamol only and avoiding aspirin (4/14, 28.6%). Two or more signs of infection were stated in 11/17 (64.7%) PILs; 7/17 (41.2%) advised applying petroleum jelly to the wound, almost all PILs highlighted the contact for postoperative problems 16/17 (94.1%), and 5/17 (29.4%) leaflets mentioned scarring. Altogether 8/17 (47.1%) of PILs advised on the timeframe until active exercise could resume postoperatively.ConclusionGuidance provided in Australian postoperative dermatological PILs is heterogeneous. A consensus checklist or template would be beneficial and ensure that advice provided to patients is more consistent; this could be adapted for local factors.
Therapeutic Drug Monitoring of Venlafaxine in an Everyday Clinical Setting: Analysis of Age, Sex and Dose Concentration Relationships

Published: April 2017

AbstractVenlafaxine is a commonly used antidepressant agent. We aimed to provide detailed information on the associations between venlafaxine dose and concentrations of venlafaxine, by patient age and sex. From a therapeutic drug monitoring (TDM) database located at Odense University Hospital, Denmark, we identified all adults for whom the treating physician had requested clinical advice on the TDM result for venlafaxine between 2002 and 2012. We identified 1077 TDM samples of venlafaxine from 334 males and 743 females (median age 45 years), and the median daily dose was 225 mg. Median plasma concentration of venlafaxine and o‐desmethylvenlafaxine (ODV) was 306 nmol/L and 861 nmol/L, respectively. The median dose‐corrected serum level for venlafaxine was 1.49 nmol/L/mg., while the dose‐corrected serum level of men and women were 1.21 nmol/L/mg and 1.60 nmol/L/mg, respectively. The dose‐corrected sum of venlafaxine and ODV was 8.91 nmol/L/mg (IQR 6.56–12.26) versus 5.52 nmol/L/mg (IQR 4.16–7.52) for patients above 64 years and below the age of 65 years, respectively. Dose‐corrected plasma concentrations of venlafaxine and ODV are increased to a clinically significant degree in patients above the age of 64, and initiation of venlafaxine therapy in the elderly should be made cautiously and supported by drug measurements.
Dealing With Social Difficulty During Adolescence: The Role of Implicit Theories of Personality
Authors: Yeager David S. 
Published: April 2017

AbstractSocial difficulty during adolescence contributes to internalizing problems (e.g., depression, stress) and spurs cycles of aggression and retaliation. In this article, I review how implicit theories of personality—beliefs about whether people can change their socially relevant characteristics—cause some adolescents to respond to social difficulty in these ways while others do not. Believing an entity theory of personality—the belief that people cannot change—causes people to blame their own and others’ traits for social difficulty, and predicts more extreme affective, physiological, and behavioral responses (e.g., depression, aggression). Interventions that teach an incremental theory of personality—the belief that people can change—can reduce problematic reactions to social difficulty. I discuss why interventions to alter implicit theories improve adolescents’ responses to conflict, and I propose suggestions for research.
Mental health and wellbeing of care leavers: Making sense of their perspectives
Authors: Sims‐Schouten Wendy , Hayden Carol 
Published: April 2017

AbstractDespite considerable quantifiable data about the circumstances of care leavers in the United Kingdom, there is less qualitative data about how these circumstances are experienced. This article is underpinned by positioning theory, with a particular focus on the unfolding personal narratives of young care leavers in relation to their mental health and wellbeing and the role of a life‐skills programme in supporting them in this respect. The research illustrates that leaving care projects, such as the one in the current study, are more focused on employment and housing issues than on addressing the mental health and wellbeing needs of young people. Our analysis of interviews with young people illustrates the ambiguity of understandings of concepts such as “mental health” and “wellbeing,” and the complexity of responses to questioning around this area. This illustrates one of the major problems in evaluating the outputs and outcomes of such projects in terms of simplistic targets, where mental health and wellbeing are not clearly defined or understood by young people themselves. The current research provides a more complex picture. More research is needed that involves in‐depth and longitudinal assessment of specific mental health needs of care leavers and how they can be addressed successfully.
A Multi‐Factor Account of Degrees of Awareness
Authors: Fazekas Peter , Overgaard Morten 
Published: April 2017

AbstractIn this paper we argue that awareness comes in degrees, and we propose a novel multi‐factor account that spans both subjective experiences and perceptual representations. At the subjective level, we argue that conscious experiences can be degraded by being fragmented, less salient, too generic, or flash‐like. At the representational level, we identify corresponding features of perceptual representations—their availability for working memory, intensity, precision, and stability—and argue that the mechanisms that affect these features are what ultimately modulate the degree of awareness. We conclude the paper by demonstrating why the original interpretations of certain empirical findings that apparently pose problems for our account are, in fact, flawed.
Preparing a Data Scientist: A Pedagogic Experience in Designing a Big Data Analytics Course

Published: April 2017

ABSTRACTIn this article, we present an experiential perspective on how a big data analytics course was designed and delivered to students at a major Midwestern university. In reference to the MSIS 2006 Model Curriculum, we designed this course as a level 2 course, with prerequisites in databases, computer programming, statistics, and data mining. Students in the class were mostly seniors or at the graduate level, and had a strong technical and quantitative background. We include details of concepts covered in the course, as well as summaries of four major sample course assignments used. Some of the concepts covered include large‐scale data collection and management using the Hadoop ecosystem, stream mining, visual analytics, and social network analytics. Besides Hadoop, the course also introduced various IBM and Teradata big data tools. We show how the course modules align with the intended learning goals and course objectives. A post‐course survey indicated that the structure and organization of the course helped students clearly and concisely assimilate the course content.
What makes fish vulnerable to capture by hooks? A conceptual framework and a review of key determinants

Published: April 2017

AbstractConsiderable time and money are expended in the pursuit of catching fish with hooks (e.g., handlining, angling, longlining, trolling, drumlining) across the recreational, commercial and subsistence fishing sectors. The fish and other aquatic organisms (e.g., squid) that are captured are not a random sample of the population because external (e.g., turbidity) and underlying internal variables (e.g., morphology) contribute to variation in vulnerability to hooks. Vulnerability is the probability of capture for any given fish in a given location at a given time and mechanistically explains the population‐level catchability coefficient, which is a fundamental and usually time‐varying (i.e., dynamic) variable in fisheries science and stock assessment. The mechanistic drivers of individual vulnerability to capture are thus of interest to fishers by affecting catch rates, but are also of considerable importance to fisheries managers whenever hook‐and‐line‐generated data contribute to stock assessments. In this paper, individual vulnerability to hooks is conceptualized as a dynamic state, in which individual fish switch between vulnerable and invulnerable states as a function of three interdependent key processes: an individual fish's internal state, its encounter with the gear, and the characteristics of the encountered gear. We develop a new conceptual framework of “vulnerability,” summarize the major drivers of fish vulnerability, and conclude that fish vulnerability involves complex processes. To understand vulnerability, a shift to interdisciplinary research and the integration of ecophysiology, fish ecology, fisheries ecology and human movement ecology, facilitated by new technological developments, is required.
“Bringing the outside world in”: Enriching social connection through health student placements in a teaching aged care facility

Published: April 2017

AbstractBackgroundOlder adults living in residential aged care facilities (RACFs) often experience limited opportunities for social connection despite close proximity to peers, which has implications for mental health and quality of life (QoL). The introduction of large‐scale undergraduate health student placements in RACFs may enhance opportunities for meaningful engagement through social connection, although this remains unexplored.ObjectiveThis research explores whether interpersonal encounters between health students and RACF residents influence residents’ opportunities for social connection and QoL.MethodsA mixed methods design was employed which included questionnaire data from residents, and qualitative interview data from residents, family members and RACF staff. Data were collected during and after student placements to allow for an in‐depth exploration of residents, family members and staff perspectives.ResultsForty‐three participants (28 residents, 10 staff and five family members) were recruited during 2014. Overall, many residents had clinical levels of depression, mild cognitive impairment and multiple morbidities, however reported moderate‐to‐good QoL. Thematic analysis was undertaken on interview transcripts, and three themes emerged: (i) social isolation and loneliness fostered by residents’ age‐related conditions, (ii) students expand socially supportive connections beyond the RACF and (iii) meaning making by sharing health experiences, which was found to help renegotiate older adults’ pervasive narrative of vulnerability.ConclusionSupported and structured health student placements in RACFs enable older adults to participate in meaningful encounters with younger people. These encounters focus on sharing health experiences and address long‐standing issues of isolation and loneliness by providing opportunities for social connection.

Published: April 2017

AbstractFused silica ceramics was prepared by using conventional organic binder, mathacrylamide‐N,N′‐methylenebisacrylamide (MAM‐MBAM) system by gelcasting process. Mechanical properties of green bodies were studied as a function of solid loading varying from 60 to 72 vol%. After evaluating the green body mechanical properties, the samples were densified at different sintering temperature from 1200 to 1450°C with definite intervals of 50°C and subjected to flexural strength analysis. Variation in flexural strength with sintering temperature was observed and correlated with the quantity of devitrification of fused silica during sintering. Quantification of devitrified cristobalite was carried out by using 20 wt% rutile (TiO2) as an internal standard by X‐ray diffraction. It was found that, as the cristobalite content increased, flexural strength decreased. Reliability studies were carried out for the samples having maximum flexural strength with and without crystalline content. Reliability studies have shown that for this organic binder system the sample sintered at 1300°C is crystalline free and most reliable product. The mechanical properties and reliability of this product processed with organic binder are compared with inorganic binder system. Results indicate that the sample fabricated using inorganic binder system is exhibiting high Weibull modulus and thus better reliability.
