Pretpostavljalo se, da se radilo o jednom, odnosno najviše dvojici autora, međutim autor teksta dokazuje da se radi o tri autora i to Canzio Michele, Da Rin Tommaso i Beda Francesco), koji su - najvjerojatnije u Genovi - imali »bottegu«, gdje su se pod navedenim signaturama izrađivali portreti i njihove kopije.The author solves the enigma of authorship in the portraits of Count Erdody and Ivan and Ana Minak (Maritime and Historical Museum of Hrvatsko Primorje in Rijeka), the portrait of a young man (Civic Museum, Karlovac) and the copy of the portrait of Count Laval Nugent (Historical Museum of Croatia, Zagreb) signed »Canzio Darin« and »Canzio Darin Beda«. lt was supposed that this referred to one or two artists at the most, but the author proves that three authors are referred to here: Canzio Michele, Da Rin Tommaso and Beda Francesco) who had a »bottega«, most likely in Genoa, where portraits and their copies were produced bearing the above mentioned signatures.L'autore cerca di risolvere i dubbi sull'autenticita del ritratto del conte Erdodyedi Giovanni ed Anna Minak (Pomorski i povijesni muzej hrvatskog primorja, Rijeka), ritratto di giovane (Gradski muzej, Karlovac) e coppia del ritratto del conte Leone Nugent (Povijesni muzej Hrvatske, Zagreb) firmati "Canzio Darin«, oppure "Canzio Darin Beda«. Si presupponeva che si trattasse di uno o all piu di due autori, mentre l'autore del testo dimostra che si tratta di tre autori cioe di: Canzio Michele, Da Rin Tommaso e Beda Francesco . I tre provenivano da una stessa bottega, che quasi sicuramente si trovava a Genova, dove si realizavano ritratti originali e coppie firmate
Description and photographs of cricket parental care in the wild
No full textAlthough certain forms of parental care are relatively widespread phenomena among insects, within Orthoptera, parental care is rare. Short-tailed burrowing crickets (Anurogryllus spp.) are among the few members of this order for which extensive parental care has been documented. However, accounts of parental care in Anurogryllus have been largely under laboratory conditions, and observations of this behavior in the wild are rare. Herein we present photographic observations from a mountain slope in Honduras where we discovered an active Anurogryllus brood chamber where an adult female was tending her brood. We present these results in the context of parental care in insects and compare our observations with those reported in past literature published on Anurogryllus crickets’ parental behavior
Gauging the Success of Timber Harvests Managed for Golden-winged Warblers (Vermivora chrysoptera): Characteristics and Territory Density within a Wetland Reference System
No full textThe Golden-winged Warbler (Vermivora chrysoptera) is an imperiled songbird that breeds in early-successional plant communities of eastern North America. Conservation efforts on the breeding grounds have become a priority because population declines are understood to be driven chiefly by the loss/degradation of breeding habitat. Although the species is known to use a variety of upland and wetland habitat types, most previous research on the species has been conducted solely in uplands. I studied Golden-winged Warbler use and habitat characteristics in the Poconos region of Pennsylvania. Density estimates suggest that both timber harvests and wetlands support similar densities of Golden-winged Warblers. Microhabitat occupancy models revealed that those wetlands I surveyed with high densities of 1-2 m tall shrubs (>2x as many shrubs) supported fewer Golden-winged Warblers whereas wetlands with more saplings (>2x as many saplings) and sedge cover (~1.3x as many sedge observations) supported more warblers. Finally, I found that macro-scale habitat variables that I quantified did not predict species occupancy of wetlands, likely due to the homogeneous nature of the study area. My study suggests that both wetlands and timber harvests have similar capacity to support Golden-winged Warblers. Further, wetlands in the Poconos should be evaluated at the microhabitat-scale for vegetative attributes that meet Golden-winged Warbler habitat requirements, rather than at the macro-habitat scale
POPULATION DYNAMICS OF SPECIES RECOVERY: MULTISCALE DEMOGRAPHY IN RESTORED HABITATS
No full textWith habitat loss remaining one of the greatest global threats to biodiversity, habitat restoration has become an important tool for species recovery and conservation. Yet despite the conceptually-appealing lens of “if you build it, they will come” (i.e., the ‘Field of Dreams’ Hypothesis), restoration outcomes are highly variable and generally lack rigorous monitoring and evaluation. Species responses to habitat restoration can vary with a wide range of factors, including life history of the focal species, multi-scale habitat attributes and local or regional demography, which highlights the need to assess species response to habitat restoration through multiple ecological frameworks. This dissertation assessed behavioral, ecological, and demographic factors affecting restoration outcomes for a Nearctic-Neotropical migratory songbird, the Golden-winged Warbler (Vermivora chrysoptera). Over the past half-century, Golden-winged Warbler populations have declined, in part, due to the loss of early-successional breeding habitat. One strategy to address declines has been to restore breeding habitat according to established and evidence-based “best management practices”. Restoration through initiatives like the Natural Resource Conservation Service’s ‘Working Lands For Wildlife’ and ‘Regional Conservation Partnership Program’ have already created > 6,000 hectares of breeding habitat since 2012, with more hectares anticipated over the coming decade. However, the response of Golden-winged Warblers to restoration remains poorly understood. In this study, we evaluated the degree to which variation in restoration outcomes were explained by habitat and landscape features, local population trends, breeding productivity, and behavioral and ecological needs at contrasting life stages (e.g., nesting, post-fledging). From 2015-2018, we surveyed male Golden-winged Warblers and measured vegetation attributes in 672 restored habitats in the Great Lakes (n = 215) and Appalachian Mountains (n = 457) regions of the breeding range. In addition to estimating occupancy, we quantified full-season reproductive productivity and survival based on the survival of 341 nests and 258 fledglings in two regions in Pennsylvania along with previously published data. Occupancy data were analyzed in program R (package unmarked) using static and dynamic occupancy models including multi-scale habitat features as model covariates, whereas nest/fledgling survival data were analyzed in program MARK to assess how components of breeding productivity varied with habitat features within focal landscapes. Our results suggest that, although Golden-winged Warblers commonly used restored habitats, occupancy probability was related to micro-habitat attributes and landscape context. Warblers were most likely to occupy structurally complex sites that were eight years post-treatment and located in landscapes with no mixed coniferous-deciduous forest within 1 km. However, even after controlling for micro-habitat and landscape attributes, occupancy rates varied widely, demonstrating that even “if you build it…” they may not come. Local breeding output (# juveniles /pair /year), was positively associated with occupancy rates, but only between focal landscapes in the Appalachian Mountains where the species was rare and declining; occupancy in Great Lakes focal landscapes were uniformly high despite intermediate levels of breeding output. In addition to regional and landscape-level variability, we found evidence that restoration outcomes differed among life stages – a pattern consistent with a growing body of literature indicating that the needs of many forest bird species differ between nesting and post-fledging periods. For Golden-winged Warblers, nest success (the probability of fledging at least one young) did not vary with micro-habitat conditions in restored habitats, but survival rates varied across life stages in ways that scaled up to yield landscape-specific differences in productivity. For example, the threefold difference in breeding output between two Appalachian landscapes (i.e., Pocono Mountains and Pennsylvania Wilds) were driven by differential nestling/fledgling ( 11 days post-fledging) survival. The greater vulnerability of nestlings and young fledglings may stem partly from developmental processes related to shifting energetic requirements and foraging development. Fledgling energetic needs are likely intense given that they replace almost all body plumage during the post-fledging period via a rapid pre-formative molt, most pronounced from 13-17 days post-fledging. Difficulty in meeting nutritional demands might also be reflected by the fact that Golden-winged Warblers began foraging almost immediately after fledging and rapidly specialized on probe-and-gape foraging (> 7 days post-fledging). Although adult Golden-winged Warblers provided extensive parental care over the post-fledging period, parental feeding may not offset the physiological and behavioral challenges faced by young fledglings during this dangerous life stage. Overall, this research provides grounds to reject the Field of Dreams Hypothesis and thereby highlights the importance of considering multi-scale habitat and demographic factors that drive restoration outcomes. Our results also emphasize the need to anticipate how stage-specific survival and life history constraints, like those we documented during the post-fledging period, may shape population-level responses to habitat restoration. This is especially important given that species conservation plans may disregard understudied life stages, including the post-fledging period. Ultimately, our analyses provide one of the most comprehensive assessments of breeding habitat restoration for an imperiled migratory songbird, while also offering new insights into the breeding biology of Golden-winged Warblers and other passerines
Efficient pipelining of nested loops : unroll-and-squash
No full textThesis (M.Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2001.Includes bibliographical references (leaves 49-50).This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.The size and complexity of current custom VLSI have forced the use of high-level programming languages to describe hardware, and compiler and synthesis technology to map abstract designs into silicon. Many applications operating on large streaming data usually require a custom VLSI because of high performance or low power restrictions. Since the data processing is typically described by loop constructs in a high-level language, loops are the most critical portions of the hardware description and special techniques are developed to optimally synthesize them. In this thesis, we introduce a new method for mapping nested loops into hardware and pipelining them efficiently. The technique achieves fine-grain parallelism even on strong intra- and inter-iteration data-dependent inner loops and, by economically sharing resources, improves performance at the expense of a small amount of additional area. We implemented the transformation within the Nimble Compiler environment and evaluated its performance on several signal-processing benchmarks. The method achieves up to 2x increase in the area efficiency compared to the best known optimization techniques.by Darin S. Petkov.M.Eng

Veb pristupačnost i elektronskih formati za pristup informacijama za osobe sa invaliditetom
No full textAuthor described the context of the development of technological and social relationships and how they mutually made changes on ways how people interact with information and access to knowledge.
The development of societies changed significantly the role of libraries and posed new technological and other challenges due to the development of information technologies.
Since the development of information technologies caused expansion of production capacities in societies there was additional need to standardize production of formats of access, distribution, archiving of information. Due to democratic character of many developed societies openness of information and human rights emphasized an importance of legal aspects and rights of persons with disabilities. Author mentioned articles of the UN Convention of Rights of Persons with Disabilities which required that parties which ratified convention should implement accessibility standards for persons with disabilities. Author presented standards and technical specifications that define accessibility of web interface, computer software and file formats. It is especially emphasized that those standards are important in libraries. Modern libraries should adopt and use file formats which are accessible for persons with disabilities in order to avoid risk of increased discrimination against persons with disabilities if inaccessible technologies will be used. Author believes that this would help persons with disability to use library resources and services equally as other users do.
