The Solent Disturbance & Mitigation Project Phase II – On-site visitor survey results from the Solent region
No full textThis report sets out the results of the on-site visitor survey component of the Solent Disturbance and Mitigation project. The work was commissioned by the Solent Forum in response to concerns over the impact of recreational pressure on features of the Solent SPA, SAC and Ramsar Sites. Of particular concern are the cumulative impacts of recreational use arising from potential new housing
developments in the Chichester District and South Hampshire.
The visitor surveys were conducted during the winter 2009/2010 to assess the level and type of visitor use at selected locations along the Solent coastline. Overall it is likely that the number of visitors interviewed and counted during the survey period was lower than would be normally be expected given the especially cold 2009/2010 winter. With that in mind, there is the potential that
the monitoring could provide an underestimate of the absolute number visitors to the region.
However, the interviews were designed to elicit generic and site specific details from visitors and
although fewer individuals may have been recorded or interviewed because of the weather we can
assume that the general winter visitation pattern remained similar and the results very useful in
understanding who, where, when and why people use the coast.
Counts of people and interviews were conducted at 20 locations around the Solent coastline
(including the north shore of the Isle of Wight). A total of 16 hours of surveys were carried out at
each location, split equally between weekend (8 hours) and a weekday (8 hours). A total of 784
interviews were conducted, accounting for 1,322 people and 550 dogs. The average group size was
1.7 people.
There were differences in visitor numbers between survey locations, with the highest visitor
numbers recorded at Emsworth (1088 visitors were recorded using the site over 16 hours) while
Lymington (Boldre/Pylewell) was the least busy (33 visitors counted over 16 hours). Visitor numbers
per day were typically highest on weekend compared to weekdays. Holiday makers accounted for
6% of the total number of visitors recorded (80 visitors). Visitors were undertook a wide range of
activities, with walking (without a dog) and dog walking the two most frequently recorded activities
(44% and 42% of interviews). Across all sites and activities, visits were typically short, with 89%
lasting less than two hours. The main modes of transport used to reach sites were by car and on
foot, with the proportion of people arriving by each mode varying between sites. Across all sites
(and taking the data for non-holiday makers only), 51% of interviewees arrived by car and a further
46% arrived on foot. Home postcodes were used to identify the distance between interviewee’s
home and the location where interviewed. Half of all visitors arriving on foot lived within 0.7km,
while half of all visitors arriving by car lived more than 4km away. Only 9% of foot visitors lived more
than 2km away compared to 80% of all car visitors.
Linear regressions using housing numbers within different distance bands of a location as a predictor
of visitor numbers for each location show a positive relationship between the number of houses
within 1km, 3km and 5km and number of visitors entering each survey location. Car park capacity at
the access points did not provide a good indication of the frequency of visitors arriving by car to each
location. The relationship is more complex, future modelling of visitor rates travelling to locations by
car should include potential road related parking (related to length of nearby roads around access
points) in addition to official and off road car parking capacity around the access points.
2
Route data were also collected for each interview, with lines drawn directly on maps during the
survey. These route data were analysed to determine which activities take place below Mean High
Water Mark (MHWM) and how far different groups go out into the intertidal. Across all the
interviews, 7% of the mapped routes did not go within 25m of MHWM and were therefore visitors
who did not actually make it to the beach (in some locations the survey point was set inland, for
example near to parking locations etc.). A further 78% were entirely within the band between 25m
above and 25m below MHWM, indicating routes that remained at the top of the beach, on the
seawall or similar. It was 14% of the mapped routes that went below 50m from MHWM, and these
included a range of activities, for example bait diggers, dog walkers, joggers, cyclists and people out
on a family outing.
The implications of the results for further modelling and in relation to the disturbance of birds on
the European Sites are discussed
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Violence Prevention Education: Problem Structuring for Systemic Empowerment in Health Settings
No full textApplying a system lens and systemic approach is valuable for exploring problem situations and difficulties. A systems understanding allows deep exploration of complexity and diversity with respect and invites multiple approaches and perspectives. Importantly, and sensitively, issues of power, dynamics and change in perspective and opportunity can be brought into clearer understandings. Solutions that value creativity and imagination can be revealed (Stephens, Lewis and Reddy, 2018).
Preventing family and community violence before it happens is a challenge. Many targeted campaigns focus on bystander actions, victim protection and support, or on the perpetrator from counselling support to lengthy jail convictions, after an event or series of violent acts have occurred. Community campaigns encourage victims of violence to get help, leave or change shared attitudes, but despite decades of concerted effort, the rate of domestic, community and family violence have not changed in Australia. Yet, every act of violence is another lived example of the failure of primary prevention.
On average, one woman a week is killed by her intimate partner (ANROWS, 2018) in Australia, from preventable violence has prompted us to reconsider the problem from the perspective of primary care and especially that of the family physician. There are significant resources devoted to the clinical response for Family Physicians whose patients reveal that they have experienced violence from someone with whom they have had a previous relationship (see for example the RACGP’s White Book, Safer Families (RACGP, 2014). The source of frustration for us as practitioners is that while family medicine physicians are expert in disease prevention and primary prevention, to date few resources have been devoted to the recognition and active prevention of violence in relationships before the initial act, at developmentally appropriate opportunities.
With a review of the sociology and neurobiology of violence and conflict analysis, we developed a problem-structuring model containing ten elements including six necessary factors that must coalesce for an act of violence to take place. Our systems application reveals these factors and their implications and strategies for change can be explored by family physicians, counsellors and health workers who are able to use this model as a tool to talk through matters with individuals, families and communities. We call this the Cooktown Ten (C-10). Coupled with mindful self-calming strategies, advocated by psychologists including Bowby and Neff (Metcalf, 2010; Neff, 2003) and our own ‘Gentle Hands’ technique, (W. Liley, 2015, 2016; W Liley & Stephens, 2018), the approach supports practitioners and clients to effectively diffuse and de-escalate tension, prejudice and isolation, and, over time, change behaviours. Self-control and self-soothing have long been an interest for systems researchers. As self-aware, writer, practitioner, researcher, activists, we acknowledge that with almost every concept we have designed from, we build on the work of others; we can because they have.
This chapter discusses the C-10 as a practical application of systemic thinking for individual and community education. Systemic thinking is a necessary tool in our repertoires of practice to deal with the almost universal problem of interpersonal harm. We will explore the paradigmatic framework that can justify clinical endeavour without waiting for a bureaucratic directive or guideline to follow. Primary healthcare has an important role to play in dealing with violence prevention, particularly where early identification can allow timely interventions
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
A 0.12mm<sup>2</sup> Wien-Bridge Temperature Sensor with 0.1°C (3σ) Inaccuracy from -40°C to 180°C
No full text Resistor-based temperature sensors can achieve much higher resolution and energy efficiency than conventional BJT-based sensors [1], but they typically occupy more area (> 0.25 mm 2 ) and have lower operating temperatures (le 125 {circ} {C}) [2]-[4]. This work describes a 0.12mm 2 resistor-based sensor that uses a Wien-bridge (WB) filter to achieve 0.1 {circ} {C} (3 sigma) inaccuracy from - 40 {circ} {C} to 180 {circ} {C}. Compared to a state-of-the-art WB sensor [4], it occupies 6 × less area and achieves comparable relative accuracy over a 76% wider operating range.

A ±25A Versatile Shunt-Based Current Sensor with 10kHz Bandwidth and ±0.25% Gain Error from -40°C to 85°C Using 2-Current Calibration
No full textAccurate current sensing is critical in many industrial applications, such as battery management and motor control. Precise shunt-based current sensors have been reported with gain errors of less than 1% over the industrial temperature range (-40°C to 85°C) [1]–[4]. However, since they are intended for coulomb counting, their bandwidth is limited to a few tens of Hz, making them unsuitable for battery impedance or motor-current sensing. This paper presents a current sensor with a wide (10kHz) bandwidth and a tunable temperature compensation scheme (TCS), which allows it to be flexibly used with different types of shunts while maintaining high accuracy. A low-cost room-temperature calibration scheme is proposed to optimize gain flatness over temperature by exploiting the shunt's self-heating at large currents. Over the industrial temperature range and a ±25A current range, it achieves state-of-the-art gain error (±0.25%) with both low-cost PCB and stable metal-alloy shunts.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Electronic InstrumentationMicroelectronic
The Solent Disturbance & Mitigation Project. Phase II – results of the Solent household survey
No full textThis report sets out the results of the postal household survey component of the Solent Disturbance and Mitigation project. The work was commissioned by the Solent Forum in response to concerns over the impact of recreational pressure on features of the Solent SPA, SAC and Ramsar Sites. Of particular concern are the cumulative impacts of recreational use arising from potential new housing developments in Chichester District and South Hampshire.
The household survey was distributed to 5000 households within 25km of the coastline between Hurst Castle, including the north shoreline of the Isle of Wight. The questionnaires and reminders were sent between October and December 2010. The household survey contained three sections which elicited information relating to general and specific visits to the coast and household demographics.
A total of 1382 completed questionnaires were returned and 42% of these households had visited the coast the week prior to completing the survey. Only 4% of households (56) stated they never visited the coast. Households which did not visit the coast contained a lower number of people, lower number of dogs and a higher percentage did not have regular access to a private vehicle when compared to households that made regular coastal visits.
Of the households which visited the coast, 50% visited at least once a week. A total of 55% of households visited the coast equally all year and an additional 39% of households made more visits in the summer. There was a significant difference in coastal visit frequency between households which owned a least one dog and non dog owning households, with dog owning households making more visits. There was no significant difference in visit frequency between households who had garden access or whether the household dwelling type was a flat or ‘non- flat’.
The 1155 households providing full responses to the survey made an estimated annual total of 153,433 visits to the Solent coastline. The project and this survey divided the coastline into 103 numbered sections. Households made on average 133 annual coastal visits to 3.7 different sections of the coastline. On average each section received a total of 1490 annual visits but the number of coastal visits made to different sections was significantly different.
The most frequently given activities undertaken during a coastal visit were walking (20% of all activity responses) and enjoying the scenery (20%), followed by being on the beach (11%) and meeting up with friends (11% of all activity responses).
Households indicated where they undertook their activity during the coastal visit and for 47% of the visit responses the activity (walking, cycling, enjoying the scenery etc) was undertaken on the sea wall or the river bank. A further 39% of responses by households indicated they venture onto the beach/mudflat and 15% of responses actually took to the water.
The majority (52%) of coastal visits by households were made by car with 39% made by foot, 4% by bicycle and 5% by public transport. Of the households which made visits by car, 50% travelled 9.5km or less by road to the section they visited and 90% travelled 29.0km or less to their visited section by road. Of the households who visited specific sections by foot half lived within 1.0km of the section (straight line distance from postcode to nearest point on section) and 90% lived within 4.0km of the visited section.
Features that act as a deterrent for some households when selecting a coastal location to visit may also attract other households. For example, a requirement for dogs to be on leads and the presence of dog restrictions is rated as attractive to non dog owning households but as a deterrent by dog owning households. By far the most popular attractive feature when households choose which coastal location to visit was ‘sea views and attractive scenery’ followed by ‘feel safe’, ‘ability to do a range of different walks/routes ‘and the ‘presence of wildlife’.
Predictions were derived by fitting formal statistical models to the observed (household survey) data.
Specifically these models used observed visitor numbers per section per distance band and analysed these in relation to factors representing distance to section and section characteristics. Different models are presented within the report and separate models were generated for car and foot visitors, with each model showing a declining visitor rate with distance from the section – i.e. the further away people live the fewer visits they make. These models suggest some 52 million visits are made each year, by households within a 30km radius of the coastline between Hurst Castle to Chichester Harbour, including the north shore of the Isle of Wight. The models identify Portsmouth’s seafront (South Parade Pier to Fort Cumberland) as the most heavily visited coastal section, with over 3 million household visits per annum.
These predictive visit models will be used alongside the bird models, commissioned separately and subject to a further report, to assess the impacts of disturbance to wintering birds under different housing scenarios. The use of the visitor models and how they will link to the bird models within the next stages of the Solent Disturbance and Mitigation Project are discussed
