They were divided into two groups based on eye dominance: dominant eye (DE) group targeting emmetropia and the nondominant eye (NDE) group targeting -0.5 D slight myopia. The uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), and retreatment rates were reported from baseline to 6 months.Results: The UNVA, UIVA, and UDVA improved significantly in both groups (Kruskal–Wallis test, DE and NDE: P<0.00001, P<0.000005, and P=0.00001, respectively). Corrected distance visual acuity (CDVA) baseline was better in both groups in comparison to UDVA at 6 months (Wilcoxon test, DE: P<0.001, 95% confidence interval (CI) of the median 0.0–0.0 LogMAR and 0.1000–0.1218 LogMAR and NDE: P=0.010, 95% CI of the median 0.0–0.0 LogMAR and 0.00–0.10 LogMAR). There was a significant loss of lines between CDVA baseline and UDVA at 6 months in both groups (DE group: 68% of eyes lost one line or more; NDE group: 58% of eyes lost one line or more). The corrected near visual acuity baseline compared to UNVA at 6 months was not statistically important (Wilcoxon test, DE: P=0.8125, 95% CI of the median 0.0–0.0 LogMAR and 0.0–0.0 LogMAR and NDE: P=0.82, 95% CI of the median 0.0–0.0 LogMAR and 0.0–0.0 LogMAR). The comparison among the UDVA, UIVA, and UNVA between the two groups at baseline and during all follow-ups was not statistically important. Two cases from the DE group were retreated (6%).Conclusion: Use of this multifocal aspheric corneal ablation profile in patients with hyperopic presbyopia significantly improved UDVA, UIVA, and UNVA. This improvement was due to created multifocality of the cornea. The mini-monovision seems not to affect UDVA, UIVA, and UNVA between the two groups. The retreatment rates at the 6-month evaluation were significantly less in our study when compared with other studies. This method seems to improve UDVA, UIVA, and UNVA but could result in a significant statistical difference between CDVA baseline and UDVA at 6 months that leads to loss of lines in distance vision. Despite promising results, this is a preliminary evaluation of this new profile, and a larger number of eyes are needed to verify visual outcomes, retreatment rates, and safety.

Le Programme d’accompagnement justice-itinérance à la cour municipale de Montréal (PAJIC) : un tribunal spécialisé ancré dans le communautaire
No full textDans cet article, nous exposons d’abord les objectifs du Programme d’accompagnement justice-itinérance à la cour municipale de Montréal (PAJIC), son histoire et son fonctionnement actuel. Nous traçons ensuite les liens entre ce Programme et la première étude sur la judiciarisation de l’itinérance à Montréal, en soulignant que dans le monde des tribunaux spécialisés, le PAJIC est un programme à part, notamment en raison de sa flexibilité et de son ancrage dans le milieu communautaire. Nous précisons enfin les défis auxquels le PAJIC fait face, en tant que réponse individuelle à la judiciarisation des personnes en situation d’itinérance.In this article we present the objectives, history and current functioning of the Justice and Court Accompaniment Program for the Homeless in Montreal (PAJIC for the French acronym). We then draw links between this program and the first study on the judicialization of homelessness, underlining that in the world of specialized courts, the PAJIC is in a different category, especially because of its flexibility and ties to the milieu of grassroots community organizations. We finally expose the challenges the PAJIC faces as an individual response to the judicialization of homeless people
Det är okej att klottra eller...? En kvantitativ studie om attityden gentemot klotter
No full textTodorovic, M & Pajic, T. Det är okej att klottra... eller? En kvantitativ studie om attityden gentemot klotter. Examensarbete i kriminologi 15 poäng. Malmö högskola: Fakulteten för Hälsa och Samhälle, Institutionen för Kriminologi, 2017.
Klotter har sedan långt tillbaka i historien varit ett samhällsproblem. Idag talas det ofta om klotter i samband med kostnader. I Sverige klassas klotter som vandalism och faller under brott för skadegörelse. Det går utifrån resultatet att dra en slutsats om att yngre män i större utsträckning har en positiv attityd gentemot klotter. Brottsförebyggande aktörer bör öka kunskapen om klotter redan i tidig skolålder.Todorovic, M & Pajic, T. It’s okay to scribble... right? A quantitative study on the attitude towards scribble. Degree project in Criminology, 15 credits. Malmö University: Faculty of Health and Society, Department of Criminology, 2017.
Scribble has for a long time been a social problem. Today, scribble is often associated with society costs. In Sweden, scribble is classified as vandalism and property damage. The conclusion of this report is that younger men have a more positive attitude toward scribble. Furthermore, the crime prevention actors should increase the knowledge of scribble already in early school age
First experience with the new high-frequency femtosecond laser system (LDV Z8) for cataract surgery

Methods: This prospective observational study was performed at the Swiss Eye Research Foundation, Eye Clinic ORASIS, Reinach, Switzerland. Fourteen patients were subjected to unilateral FLACS. Capsulotomy and lens fragmentation were performed with the aid of the LDV Z8 femtosecond laser system. Ease of phacoemulsification (on a 4-point scale), completeness of capsulotomy (on a 10-point scale), time for preparation of femtosecond laser (minutes), effective phacoemulsification time (seconds), total duration of surgery (minutes), and safety of the procedure were evaluated. Results: Ease of fragmentation and completeness of capsulotomy were estimated at 3.9 and 9.9, respectively. The preparation time for femtosecond was 3.6±0.7 minutes, effective phacoemulsification time was 2.5±3.1 seconds, and total duration of the FLACS procedure was 16.3±4.5 minutes. No major complications were observed. Approximately 42% of all patients (6/14) showed Descemet’s folds directly postoperatively. Conclusion: FLACS with the LDV Z8 system was characterized by complete capsulotomy and highly effective and reproducible lens fragmentation. The safety of the procedure was very good as perceived by the surgeon operating in this observational case series. The cost to benefit ratio should be further debated by assessing the results of a major prospective study, which is required for valid evaluation of the efficiency and safety of the LDV Z8 laser system and of FLACS in general. Keywords: femtosecond laser, cataract surgery, effective phacoemulsification time, complication
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
