Comportamiento alimenticio del insecto defoliador nativo 4 Perzelia arda (Clarke, 1978) (Lepidoptera: Depressariidae)
No full textEn el bosque Andino-Patagónico, la vegetación arbórea dominante está representada por ejemplares del género Nothofagus (Nothofagaceae), los cuales representan un recurso natural preciado. Es por ello que es de gran importancia conocer el impacto que pueden ocasionar determinados agentes de daño, como los insectos herbívoros, y como estos daños varían según las interacciones con factores bióticos y abióticos. La oruga nativa Perzelia arda se alimenta de las hojas de varias especies de Nothofagus, sin embargo, se desconocen aspectos del daño que ocasiona en estos bosques. El objetivo general de mi tesis fue, estudiar el comportamiento alimenticio de las larvas de P. arda y determinar su potencial impacto sobre N. alpina, N. obliqua, N. antarctica y N. pumilio. Para ello, evalué las preferencias alimenticias de P. arda por medio de pruebas de a pares. Luego, estudié el efecto de tres temperaturas (6°C, 22°C y 28°C) sobre la herbivoría. Por último, analicé si la presencia de un ácaro en las hojas de N. obliqua influía sobre el consumo y la elección de las hojas por parte de las larvas. Mis resultados demuestran que P. arda elige a todas las especies por igual. Sin embargo, no se alimenta de ellas en la misma proporción, esto depende de la oferta de los estímulos. Existe un efecto de interacción entre la temperatura y la especie sobre la herbivoría, con un mayor consumo a 22 ° C para todas las plantas, excepto para N. obliqua, que presentó mayor consumo a 6 ° C. La presencia de los ácaros no afectó las preferencias alimenticias, ni la herbivoría. Puedo concluir que la composición vegetal del bosque y la temperatura ambiental influyen en la susceptibilidad de herbivoría por parte de P. arda. Mi investigación contribuye a una mayor comprensión sobre la compleja interacción insecto-planta en el bosque nativo.Fil: Capobianco, Julio Nahuel. Universidad Nacional del Comahue.

Art Arda Dizi İzleme Alışkanlığı ve Anlatıya Dahil Olma İlişkisi
No full textYeni medya teknolojileri, izleyici alışkanlıklarını ve izleyicinin anlatıya dahil olma biçimlerini hem değiştirdi hem de çeşitlendirdi. Son yıllarda izleyicilerin dizi izlemek için isteğe bağlı video platformlarını kullanmasının artmasıyla birlikte binge watching, art arda izleme davranışı, yaygınlaşan bir fenomen oldu. Artık medya tüketicileri televizyon içeriklerine istedikleri zaman, farklı ekranlardan erişim sağlayabiliyor. İzleyicilerin kaçış ve eğlenme motivasyonlarıyla dizilerin bölümlerini art arda izledikleriyle ilgili ulusal ve uluslararası çalışmalar mevcut. Fakat bu aşırı izleme davranışının psikolojik süreçleri ve etkileriyle ilgili şimdiye kadar yapılan çalışmalar yeterli değildir. Bu çalışma, televizyon dizilerinin bölümlerini isteğe bağlı video platformlarından art arda izlemenin izleyicinin anlatıya dahil olma ve özdeşleşme değerlerine olan etkisini araştırır. Çevrimiçi bir anketle 435 Türk katılımcının aşırı izlemenin, anlatıya dahil olma ve karakterlerle özdeşleşmeyle olan ilişkisi araştırıldı. Sonuçlara göre art arda izleme sıklığı izleyicinin anlatıya dahil olmasını derinleştirmektedir. Ayrıca karakterlerle daha güçlü bir özdeşleşme kurmayı etkilemektedir. Dijital dağıtım sadece ileriye gidecek bir akım olduğundan akış platformları izleme alışkanlıklarını etkilemeye ve dönüştürmeye devam edecek. Anahtar Sözcükler: binge watching, aşırı izleme, art arda izleme, anlatıya dahil olma, özdeşleşme, çevrimiçi dizi platformlarıNew media technologies have enabled the diversification of viewing habits and audience engagement. Binge watching has become a prevalent phenomenon with the increasing use of video-on-demand platforms for watching online series in recent years. Media consumers can now watch television content on different screens with self-scheduled viewing behaviors. It is known that binge watching can be motivated by escapism or enjoyment, but its psychological processes and effects are understudied. This study explores whether binge-watching online series on digital streaming platforms is associated with greater narrative engagement and increased identification with the characters. An online survey (N=435) of Turkish viewers was conducted to investigate the associations between binge watching and narrative engagement and identification with characters. The results indicated that the frequency of binge watching is associated with stronger identification with characters and narrative engagement. Digital distribution is a trend that will only move forward, and streaming platforms will continue to change viewing behaviors. Keywords: binge watching, narrative engagement, identification, streaming platforms, online serie
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
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
Host plant choice and effect of temperature on feeding behaviour of Perzelia arda (Lepidoptera: Depressariidae), a leaf-tying larva, on Nothofagaceae from the Andean Patagonian forest
No full textEnvironmental temperature may cause changes in the physiology and feeding behaviour of herbivorous insects and, consequently, in the damage they can cause. In the Andean Patagonian forest, an eco-region dominated by trees of the Nothofagaceae family, it is common to find the leaf-tying larvae Perzelia arda consuming seeds and leaves of several species of Nothofagus genus. The pattern of damage caused by P. arda in these forests varies from year to year and even within seasons. We hypothesise that this phenomenon may be related to an increase in the ambient temperature of this region. The purpose of this work was to determine the host
plant preferences of P. arda among four species of Nothofagus genus and to evaluate whether temperature influences the feeding behaviour of the larvae. We first evaluated the food preferences of P. arda by means of twochoice tests, using leaves of N. alpina, N. obliqua, N. antarctica and N. pumilio as stimuli. Secondly, we evaluated the effect of three levels of temperature on herbivory. Our results demonstrated that P. arda feed on and equally choose the four species of host plants studied. Temperature influenced the feeding behaviour of the larvae; high levels of consumption of N. obliqua occurred at 6°C and differed for the other host plant suggesting that consumption also depends on the type of food resource. In conclusion, the feeding behaviour of P. arda depends on
a complex interaction between host plant and abiotic conditions. Further studies are required for a better understanding about the use of resources by this native insect, as well as the ecological consequences.Estación Experimental Agropecuaria BarilocheFil: Capobianco, Julio Nahuel.

Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Comparison of Laying Performance, Egg Quality and Bone Characteristics of Commercial and Türk Laying Hen Genotypes Kept in a Free-Range System
No full textThis study was designed to compare of laying performance, egg quality and bone
characteristics of commercial and Türk laying hen genotypes kept in free-range system.
A total of 720 laying hens (Atabey, Lohmann White, Atak-S, Lohmann Brown; n=180
hens/genotype) were used in the experiment. Production performance was determined
as the mean of egg production, egg weight, and FCR value between 54 and 66 weeks of
age. Egg quality parameters and bone characteristics of tibia and femur were measured at
66 weeks of age. The mean value of egg production was found to be higher in Lohmann
Brown and Lohmann White genotypes compared to Atak-S and Atabey genotypes
between 54 and 66 weeks of age (P<0.01). The brown eggs obtained from (Lohmann
Brown, Atak-S) genotypes tended to be heavier than the white hen genotypes (Lohmann
White, Atabey). The lowest mean value of FCR was observed in Lohmann White hens
ranged from during the experimental period. The Lohmann Brown and Atak-S eggs
obtained from (3.350 g/cm2 and 3.300 g/cm2) had a stronger shell strength compared to
the Lohmann White and Atabey (2.847 g/cm2 and 2.910 g/cm2, P<0.01). The breaking
strength of tibia was found to be higher in brown hens (366.0 N and 381.2 N) than white
hens (267.0 N and 322.2 N) (P<0.01). These findings related to different genotypes could
be instructive for arranging new management rules and nutritional advice for stronger
eggshell and bone strength of hens in free range system
Dissipative Range Scaling of Higher Order Structure Functions for Velocity and Passive Scalars
No full textDifferently to Kolmogorov's second similarity hypothesis, we find that the 2n-th order velocity and scalar structure functions scale with n-th order moment of the energy dissipation and the scalar dissipation, respectively. The origins of this scaling are analyzed by the transport equations of the fourth order velocity and scalar increment moments and by direct numerical simulations
