Effects of scale and the biophysical environment on sense of place in northeastern Wisconsin\u27s bioregions
Understanding individuals’ and groups’ sense of place can provide insights into how people interact with and treat both natural and built environments, and inform understandings of proenvironmental behavior, place-protective action, management of regional amenities, participatory landscape planning, and environmental education initiatives. Notwithstanding these invaluable contributions, the empirical place scholarship has paid relatively little attention to several key dynamics, including the existence and implications of broad-scale sense of place, whether sense of place occurs in low- or mixed-amenity areas, and the biophysical (and bioregional) dimensions of sense of place. Accordingly, this empirical, phenomenological study investigates the scale at which sense of place develops and operates among a subset of residents engaged in watershed conservation activities in northeastern Wisconsin’s mixed-amenity coastal communities. The following questions guided our 5 research: 1) How do mixed-amenity bioregions contribute to people’s sense of place? 2) What sorts of biophysical characteristics, meanings, and/or experiences affect their sense of place? 3) How does this sense of place impact their reported proenvironmental behaviors? In total, 22 semi-structured, in-depth interviews were conducted individuals whose primary residence was in the Fox River Valley bioregion, and who were vocationally or avocationally involved in water-quality improvement and/or broad-scale conservation activities in northeast Wisconsi
Interactive deep maps and spatial narratives for landscape conservation and public engagement
Landscape conservation science and practice has increasingly embraced a “people and nature” paradigm that recognizes the dynamic complexity and bidirectional relationships in social-ecological systems. Conservation research remains heavily biased toward the ecological dimensions of conservation, with socially focused research taking up a relatively small fraction. The digital revolution and accompanying geospatial web inspired platforms and methods that provide a significant opportunity for closing this divide. This article focuses on potential contributions to conservation science and practices from one such integrative platform—interactive deep maps and their resulting spatial narratives— that digitally combine the qualitative and experiential essence(s) of place with the quantitative capabilities of Cartesian space. By critically exploring emerging work, we propose that interactive deep maps and spatial narratives are uniquely positioned for integrating social and ecological dimensions of place-based conservation by linking the lived experiences of people with the spatially represented ecological characteristics of nature
Participatory mobile- and web-based tools for eliciting landscape knowledge and perspectives: introducing and evaluating the Wisconsin geotools project
Despite synergistic goals across a wide breadth of fields and modalities, coastal landscape conservation projects that engage the lay public and integrate narratives of place remain elusive. This paper addresses these needs by introducing and evaluating the Wisconsin Geotools, an integrated pair of mobile-and web-based applications that allow users to generate and share spatially defined multimedia observations — including photos, short textual descriptions (or journals), and audio and video clips — of their surrounding bioregional landscapes. We followed a participatory, user-centered design process to develop a mobile application that uses GPS capabilities to geolocate multimedia observations of landscapes and feed them into a web-based application, which displays content through the structure of an interactive story map. The applications were piloted with coastal community user groups in Green Bay (Lake Michigan), Wisconsin, USA. Over 800 observations were recorded by participants in our study area. Results from a user evaluation survey indicate the geotools effectively engaged participants in learning about and exploring their surrounding coastal landscapes. A spatial analysis revealed participants’ affinity for water-related features in landscapes. We close by suggesting a variety of ways in which these tools can support future projects and existing methodologies that are advancing transdisciplinary approaches to engaging the public in coastal conservation
No difference in strength and clinical outcome between early and late repair after Achilles tendon rupture
PURPOSE: This retrospective study aimed to determine the patient-reported and functional outcome of patients with delayed presentation, who had received no treatment until 14 days following injury of Achilles tendon rupture repaired with minimally invasive surgery and were compared with a group of sex- and age-matched patients presenting acutely. Based on the outcomes following delayed presentation reported in the literature, it was hypothesized that outcomes would be inferior for self-reported outcome, tendon elongation, heel-rise performance, ability to return to play, and complication rates than for acutely managed patients.
METHODS: Repair was performed through an incision large enough to permit mobilisation of the tendon ends, core suture repair consisting of a modified Bunnell suture proximally and a Kessler suture distally and circumferential running suture augmentation.
RESULTS: Nine patients presented 21.8 (14.9) days (range 14-42 days) after rupture. The rate of delayed presentation was estimated to be 1 in 10. At 12 months following repair, patients with delayed treatment had median (range) ATRS score of 90 (69-99) compared with 94 (75-100) in patients treated acutely presenting 0.66 (1.7) (0-5) days. There were no significant differences between groups: ATRA [mean (SD) delayed: - 6.9° (5.5), acute: - 6° (4.7)], heel-rise height index [delayed: 79% (20), acute: 74% (14)], or heel-rise repetition index [delayed: 77% (20), acute: 71% (20)]. In the delayed presentation group, two patients had wound infection and one iatrogenic sural nerve injury.
CONCLUSIONS: Patients presenting more than 2 weeks after Achilles tendon rupture may be successfully treated with minimally invasive repair.
LEVEL OF EVIDENCE: III
Age and tightness of repair are predictors of heel-rise height after Achilles tendon rupture
Background: Achilles tendon rupture leads to weakness of ankle plantarflexion. Treatment of Achilles tendon rupture should aim to restore function while minimizing weakness and complications of management.
Purpose: To determine the influence of factors (age, sex, body mass index [BMI], weight, time from injury to operative repair, and tightness of repair) in the initial surgical management of patients after an acute Achilles tendon rupture on 12-month functional outcome assessment after percutaneous and minimally invasive repair.
Study Design: Cohort study; Level of evidence, 3.
Methods: From May 2012 to January 2018, patients sustaining an Achilles tendon rupture receiving operative repair were prospectively evaluated. Tightness of repair was quantified using the intraoperative Achilles tendon resting angle (ATRA). Heel-rise height index (HRHI) was used as the primary 12-month outcome variable. Secondary outcome measures included Achilles tendon total rupture score (ATRS) and Tegner score. Stepwise multiple regression was used to create a model to predict 12-month HRHI.
Results: A total of 122 patients met the inclusion criteria for data analysis (mean ± SD age, 44.1 ± 10.8 years; 78% male; mean ± SD BMI, 28.1 ± 4.3 kg/m
Conclusion: Age was found to be the strongest predictor of outcome after Achilles tendon rupture. The most important modifiable risk factor was the tightness of repair. It is recommended that repair be performed as tight as possible to optimize heel-rise height 1 year after Achilles tendon rupture and possibly to reduce tendon elongation
Conodonts from the “Pelmatozoan Limestone” (Upper Ordovician), northern Sevilla, Ossa-Morena Zone (Spain)
27 páginas, 1 figura, 2 tablas, 2 láminas.[EN] Several limestone levels of the “Caliza de Pelmatozoos” were sampled for conodonts in sections of the
Cerrón del Hornillo and Valle synclines. The conodont fauna includes: Amorphognathus ordovicicus, A. aff. ordovicicus,
Amorphognathus sp., Amorphognathus? sp., Drepanoistodus cf. suberectus, Drepanoistodus? sp., Hamarodus
europaeus, Icriodella cf. superba, Istorinus erectus, Panderodus gracilis, Plectodina tenuis?, Sagittodontina robusta,
Scabbardella altipes, Scabbardella sp A., Walliserodus amplissimus? y Walliserodus? sp. This association is attributed
to the Amorphognathus ordovicus Zone by the presence of the index species, and to the Sagittodontina-Scabbardella
Biofacies of the Mediterranean Province of conodonts by the relative abundance of these two taxa. This fauna is close
related to coeval associations from several localities of the Iberian Peninsula, except that of the Malaguide Complex,
but the presence of Plectodina and Drepanoistodus suggest possible faunal exchange with Anglo-Baltic faunas.[ES] El estudio para conodontos de numerosos niveles de la “Caliza de Pelmatozoos” en secciones de los sinclinales
del Cerrón del Hornillo y del Valle ha permitido identificar los taxones: Amorphognathus ordovicicus, A. aff.
ordovicicus, Amorphognathus sp., Amorphognathus? sp., Drepanoistodus cf. suberectus, Drepanoistodus? sp.,
Hamarodus europaeus, Icriodella cf. superba, Istorinus erectus, Panderodus gracilis, Plectodina tenuis?,
Sagittodontina robusta, Scabbardella altipes, Scabbardella sp A., Walliserodus amplissimus? y Walliserodus? sp. Esta
asociación, que se adscribe a la Provincia Mediterránea de conodontos, es atribuida a la Zona de Amorphognahus ordovicicus,
Kralodvoriense, por la presencia del taxón nominal. Dentro de esta provincia ha sido posible identificar la
Biofacies de Sagittodontina-Scabbardella por la abundancia relativa de ambos taxones. Si bien existe una gran similitud
entre esta fauna y las de edad equivalente reconocidas en el ámbito de dicha provincia, la presencia de Plectodina
y Drepanoistodus sugieren que el área de estudio se encontraba emplazada en latitudes más bajas que el resto de la
Península Ibérica, exceptuando la del Complejo Maláguide, y que este hecho favoreció el intercambio faunal con las
provincias Británica y Báltica de conodontos.Este trabajo es una contribución al proyecto

Is heavy eccentric calf training superior to wait-and-see, sham rehabilitation, traditional physiotherapy and other exercise interventions for pain and function in mid-portion Achilles tendinopathy?
Background: Mid-portion Achilles tendinopathy (AT) is prevalent amongst athletic and non-athletic populations with pain, stiffness and impaired function typically reported. While different management options exist, loading protocols remain the best available intervention and have been shown to be effective in the management of AT. Trials investigating loading in AT have used a variety of different protocols, and recent narrative reviews suggest that no protocol is superior to another when comparing outcomes in pain and function. However, there has been no systematic review or meta-analysis completed to determine this. Furthermore, the narrative review did not consider wait-and-see or sham interventions, thus a systematic review and met-analysis which includes wait-and see or sham interventions is warranted.
Methods: A systematic review and meta-analyses will be conducted as per the PRISMA guidelines. The databases PUBMED, CINAHL (Ovid) and CINAHL (EBSCO) will be searched for articles published from inception to 31 December 2017. Our search focuses on studies examining the improvement of pain and function when completing a loading program for mid-portion AT. Only randomised/ quasi-randomised trials will be included while case reports and case series will be excluded. The primary outcome assessing pain and function will be the Victorian Institute Sports Assessment - Achilles (VISA-A). Two reviewers will screen articles, extract data and assess the risk of bias independently with a third reviewer resolving any disagreements between the two reviewers. A meta-analysis will then be performed on the data (if appropriate) to determine if the traditional heavy load calf training protocol described by Alfredson is superior to wait-and-see, sham intervention, traditional physiotherapy, and other forms of exercise rehabilitation.
Discussion: This systematic review and meta-analysis will allow us to investigate if there are difference in pain and function when comparing wait-and-see, sham interventions, traditional physiotherapy and different exercise interventions to the traditional heavy eccentric calf training protocol for mid-portion Achilles tendon pain.

Theory of vortex excitation imaging via an NMR relaxation measurement
The temperature dependence of the site-dependent nuclear spin relaxation time
T_1 around vortices is studied in s-wave and d-wave superconductors.Reflecting
low energy electronic excitations associated with the vortex core, temperature
dependences deviate from those of the zero-field case, and T_1 becomes faster
with approaching the vortex core. In the core region, T_1^{-1} has a new peak
below T_c. The NMR study by the resonance field dependence may be a new method
to prove the spatial resolved vortex core structure in various superconductors.Comment: 5 pages, 3 figure
Zeeman Perturbed Cu Nuclear Quadrupole Resonance Study of the Vortex State of YBaCuO
We report a Cu nuclear quadrupole resonance (NQR) study of the vortex
state for an aligned polycrystalline sample of a slightly overdoped high-
superconductor YBaCuO (92 K) at a low magnetic
field of 96 mT along the c axis, near a lower critical field . We
observed the frequency distribution of the nuclear spin-lattice relaxation time
in the Zeeman-perturbed Cu NQR spectrum below . The
characteristic behavior of 1/, taking the minimum values with respect
to temperature and frequency, indicates the significant role of
antiferromagnetic spin fluctuations in the Doppler-shifted quasiparticle energy
spectrum inside and outside vortex cores.Comment: 4 pages, 4 figure
