The Vegetational and Environmental Development of Lina Mire, Gotland from 6900-400 BC
No full textLina Mire, Gotland, is an area of archaeological significance and has a complex history of shoreline displacement. Archaeologists suspect that Lina Mire was once part of an important inland water system which connected the Littorina Sea with central Gotland. This study investigates vegetational and palaeoenvironmental changes of the Lina Mire area between 6900 – 400 BC (8850 – 2350 cal years BP) in order to better understand how the area has developed and how humans have impacted the vegetation. Pollen analysis, C/N ratios, organic matter and carbon content measurements were conducted. The chronology was based on 14C AMS dating of terrestrial macrofossils and bulk sediments. A transgression of the Littorina Sea at about 6550 BC (8500 cal years BP) inundated the Lina Mire basin, which was a lake at the time. The onset of cultivation was indicated by the presence of Hordeum (Barley or Wild Barley) during the Late Neolithic, 2630 BC (4580 cal years BP). Hordeum continued to grow during the Bronze Age when Cereals appeared at about 970 BC (2920 cal years BP). During the onset of cultivation during the Late Neolithic, the Lina Mire basin was a bay of the Littorina Sea. The Lina Mire basin remained connected with the Littorina Sea until isostatic uplift caused it to become isolated at about 1870 BC (3820 cal years BP). The lake overgrew and became a mire about 820 BC (2770 cal years BP)

This is my hometown! The role of place attachment, congruity, and self-expressiveness on residents’ intention to share a place brand message online
No full textIn a gradually more hypercompetitive global tourism arena, destination marketers are increasingly seeking effective ways to promote places through appealing place brand messages. Local residents can be valuable ambassadors for the place, as well as co-creators of place-related brand communication. However, research focusing on place advertising from the residents’ perspective is scant. To address this gap, this work identifies three main antecedents of residents’ intention to share a place brand message online: place attachment, place ad–brand congruity, and self-expressiveness. A model is developed and tested on a sample of current and former residents of a Swedish city. Structural equation model results support that these antecedents have a positive influence on current as well as former residents’ intention to share a place brand ad online. Place attachment also has a significant indirect influence on intention to share, with place ad–brand congruity and self-expressiveness as partial mediators. Furthermore, place ad–brand congruity mediates partially the relationship between place attachment and self-expressiveness
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
Indocyanine green angiographic findings in young patients with Gronblad-Strandberg syndrome
No full textPurpose - The objective of the present investigation was to define the indocyanine green (ICG) angiographic features of angioid streaks (AS) in young patients with Gronblad-Strandberg syndrome and to compare them with findings on fluorescein angiography (FA) and red-free photographs. Methods: Complete ophthalmological examination, red-free photography, FA and ICG angiography were performed on 6 patients, 4 women and 2 men, ranging in age from 21 to 33 years, with Gronblad-Strandberg syndrome. Results: ICG angiography showed AS in the form of hypofluorescent lines with numerous associated hyperfluorescent foci, The AS were more clearly visualized and were seen to be more numerous and larger by ICG angiography, Choroidal neovascularization (CNV) and macular involvement had become bilateral in all of the cases. ICG angiography allowed precise localization of CNV in some cases, but it was not much superior to FA in the determination of CNV and the visualization of 'peau d'orange', Conclusions: ICG angiography provides some information different from FA in the evaluation of AS, but usually neovascular complications and peau d'orange appearance could be seen more clearly in the red-free photographs and FA. The hypofluorescent AS pattern was significantly observed in young patients with Gronblad-Strandberg syndrome. Copyright (C) 2001 S. KargerAG, Basel

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
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
