Does Alberta have a Spending Problem?

Alberta spent the better part of the last decade of the 20th century becoming the paragon of fiscal virtue.1 Following a 1993 election fought over the nature of Alberta’s spending, the Alberta government set the standard for having a clean and closely controlled fiscal framework by vigorously reducing its expenditures. And it reaped the rewards by paying down its debt and making tax cuts that enhanced critical productivity, including the move to a single rate of personal income tax.The recent return to deficits in Alberta has raised the question of whether the province has a spending problem. The answer to this question has important implications for how the province addresses its deficit. If Alberta has a spending problem, it makes sense to focus on expenditure reductions to reduce the deficit. If not, then relying on economic growth or tax increases might be the appropriate response

Public Sector Wage Growth in Alberta

In recent years, Alberta’s fiscal stance has shifted from large surpluses to deficits, and a large part of the blame appears to be due to rising public sector salaries. Since 2000, the province’s public sector wage bill has shot up by 119 percent — almost double the rate of growth in the rest of Canada. Wages, previously roughly at par with the rest of the country, are now higher (in many cases very substantially) across all public sector categories, including health care, social services, education and government, consuming 95 percent of the increase in provincial revenues over the past decade. At the same time, the number of public sector employees has grown faster than the overall population; it is difficult to attribute this sharp uptick to a rise in productivity, or the need to compete with private industry for skilled workers. This paper breaks down the increases in every category, arguing that if the provincial government is looking to trim expenditures, public sector salaries are a good place to start. The authors make their case using detailed Statistics Canada data, throwing down the gauntlet to defenders of the status quo and challenging them to justify these disparate increases

Lake Store Finnsjøen – a key for understanding Lateglacial/early Holocene vegetation and ice sheet dynamics in the central Scandes Mountains

The Lateglacial (LG) deglaciation and vegetation development in the Scandes Mountains has been debated for a century. Here we present new evidence from microfossils, radiocarbon dated plant macrofossils and sedimentary ancient DNA from laminated sediments in Lake Store Finnsjøen (1260 m a.s.l.) at Dovre, Central Norway. Combined with previous results from three other Dovre lakes, this allows for new interpretations of events during and immediately after the LG deglaciation. The Finnsjøen sediments present the first uninterrupted record of local vegetation development in the Scandes Mountains from the late Younger Dryas (YD), ca 12,000 cal years BP, to the early Holocene around 9700 cal years BP. The local vegetation in late YD/early Holocene was extremely sparse with pioneer herbs (e.g. Artemisia norvegica, Beckwithia, Campanula cf. uniflora, Koenigia, Oxyria, Papaver, Saxifraga spp.) and dwarf-shrubs (Betula nana, Salix including Salix polaris). From 11,300 cal years BP, local vegetation rapidly closed with dominant Dryas, Saxifraga spp., and Silene acaulis. From ca 10,700 cal years BP, open birch-forests with juniper, Empetrum nigrum and other dwarf-shrubs developed. Pine forests established within the area from 10,300 cal years BP. We identified the cold Preboreal Oscillation (PBO), not earlier described from pollen data in South Norway, around 11,400 cal years BP by a regional pollen signal. Distinct local vegetation changes were not detected until the post-PBO warming around 11,300 cal years BP. Apparently, the earlier warming at the YD/Holocene transition at 11,650 cal years BP was too weak and short-lived for vegetation closure at high altitudes at Dovre. For the first time, we demonstrate a regional glacier readvance and local ice cap formations during the YD in the Scandes Mountains. In two of the deep lakes with small catchments, YD glaciation blocked sedimentation without removing old sediments and caused a hiatus separating sediments of the ice-free LG interstadial (LGI) from those of the ice-free Holocene period. Both regional glaciers and local ice caps caused hiati. Ice-free pre-YD conditions at Dovre followed by a YD readvance point to a scenario that is intermediate between the maximum ice model postulating a thick glacier during the entire LG, and the minimum ice model postulating thin and multi-domed early LG ice

Spatial and temporal genetic structuring in yellow-eyed penguins

Improving our understanding of the forces driving population decline and the processes that affect the dynamics of threatened populations is central to the success of conservation management. The application of genetic tools, including our ability to examine ancient DNA, has now revolutionised our ability to investigate these processes. The recent human settlement of the Pacific, particularly in New Zealand, provides a unique, accessible system for revealing anthropogenic impacts on native biota. In this thesis I use genetic analyses from modern, historic and subfossil DNA to investigate temporal and spatial genetic structuring of the endangered yellow-eyed penguin (Megadyptes antipodes), and use these analyses to answer questions related to the conservation of this species. The yellow-eyed penguin is endemic to the New Zealand region and currently breeds on the subantarctic Auckland and Campbell Islands and the southeast coast of the South Island. The current total population size is estimated around 6000-7000 individuals, of which more than 60% inhabit the subantarctic. Despite intensive conservation measures by governmental and local community agencies, population sizes have remained highly unstable with strong fluctuations in numbers on the South Island. The species was believed to be more widespread and abundant before human colonisation of New Zealand, thus current management assumed the mainland population to be a declining remnant of a larger prehistoric population. Genetic and morphological analyses of subfossil, historic and modern penguin samples revealed an unexpected pattern of penguin extinction and expansion. Only in the last few hundred years did M. antipodes expand its range from the subantarctic to the New Zealand mainland. This range expansion was apparently facilitated by the extinction of M. antipodes' previously unrecognised sister species, M. waitaha, following Polynesian settlement in New Zealand. The demise of M. waitaha is the only known human-mediated extinction of a penguin species. Despite M. antipodes' recent range expansion, genetic analyses of microsatellite markers reveal two genetically and geographically distinct assemblages: South Island versus subantarctic populations. We detected only two first generation migrants that had dispersed from the subantarctic to the South Island, suggesting a migration rate of less than 2%. Moreover, the South Island population has low genetic variability compared to the subantarctic population. Temporal genetic analyses of historic and modern penguin specimens further revealed that the harmonic mean effective population size of the M. antipodes South Island population is low ( <200). These findings suggest that the South Island population was founded by only a small number of individuals, and that subsequent levels of gene flow have remained low. Finally, we present a novel approach to detect errors in historic museum specimen data in cases where a priori suspicion is absent. Museum specimens provide an invaluable resource for biological research, but the scientific value of specimens is compromised by the presence of errors in collection data. Using individual-based genetic analysis of contemporary and historic microsatellite data we detected eight yellow-eyed penguin specimens with what appear to be fraudulently labelled collection locations. This finding suggests errors in locality data may be more common than previously suspected, and serves as a warning to all who use archive specimens to invest time in the verification of specimen data. Overall, yellow-eyed penguins have a remarkable dynamic history of recent expansion, which has resulted in two demographically independent populations. These results reveal that anthropogenic impacts may be far more complex than previously appreciated

Orientadora: Profª Drª Fábia BerlattoMonografia (especialização) - Universidade Federal do Paraná, Setor de Ciências Humanas, Curso de Especialização em Sociologia Política.Inclui referências: [26-27 p.]Resumo: Esta pesquisa tem o objetivo de refletir sobre a crescente expansão do sistema prisional e os processos de criminalização diante das desigualdades brasileiras. Sendo assim, este estudo consistiu em analisar as contribuições de autores como Loïc Wacquant e Augusto Thompson. Este trabalho se estrutura em dois capítulos. No primeiro, será apresentado o desenvolvimento do sistema prisional brasileiro, seu histórico e como ele atua no momento atual. O segundo capítulo abordará análises de diferentes autores sobre este tema, verificando que o encarceramento tem funcionado como mecanismo de regulação social e a justiça criminal julgado preferencialmente grupos sociais e não atos criminosos. Desta forma, se propõe uma reflexão sobre o avanço das políticas neoliberais sobre o âmbito da segurança pública. Sob este registro, há uma emergência de um "Estado policial e penal" em detrimento de um "Estado de bem- estar social"

L'habileté des élèves du district fédéral du Brésil à estimer des résultats de calculs

Cette recherche vise deux objectifs: (1) évaluer l'habileté des élèves brésiliens à estimer des résultats de calculs, et (2) mettre en évidence les stratégies qu'ils utilisent pour faire de telles estimations. Pour atteindre le premier, nous avons administré à l’aide du rétroprojecteur un test à 197 élèves de 5e et 172 de 8e année provenant de trois écoles (une privée et deux publiques) du Brésil. Pour réaliser le second, nous avons fait des entrevues cliniques avec 16 sujets, choisis parmi les précédents d'après leur rendement fort, moyen ou faible au test d'estimation. Les résultats obtenus montrent que les élèves des deux niveaux sont très faibles dans l'estimation de résultats de calculs, qui n'est pas enseignée à l'école. La plupart n'emploient qu'une stratégie d'estimation: la stratégie frontale. Les élèves de 8e année affichent un rendement nettement supérieur, de même que les élèves provenant de l'école privée. Les garçons obtiennent de meilleurs résultats que les filles.Québec Université Laval, Bibliothèque 201

Ecological globalisation, serial depletion and the medieval trade of walrus rostra

The impacts of early ecological globalisation may have had profound economic and environmental consequences for human settlements and animal populations. Here, we review the extent of such historical impacts by investigating the medieval trade of walrus (Odobenus rosmarus rosmarus) ivory. We use an interdisciplinary approach including chaîne opératoire, ancient DNA (aDNA), stable isotope and zooarchaeological analysis of walrus rostra (skull sections) to identify their biological source and subsequent trade through Indigenous and urban networks. This approach complements and improves the spatial resolution of earlier aDNA observations, and we conclude that almost all medieval European finds of walrus rostra likely derived from Greenland. We further find that shifting urban nodes redistributed the traded ivory and that the latest medieval rostra finds were from smaller, often female, walruses of a distinctive DNA clade, which is especially prevalent in northern Greenland. Our results suggest that more and smaller animals were targeted at increasingly untenable distances, which reflects a classic pattern of resource depletion. We consider how the trade of walrus and elephant ivory intersected, and evaluate the extent to which emergent globalisation and the “resource curse” contributed to the abandonment of Norse Greenland

Ancient DNA reveals the chronology of walrus ivory trade from Norse Greenland.

The importance of the Atlantic walrus ivory trade for the colonization, peak, and collapse of the medieval Norse colonies on Greenland has been extensively debated. Nevertheless, no studies have directly traced medieval European ivory back to distinct Arctic populations of walrus. Analysing the entire mitogenomes of 37 archaeological specimens from Europe, Svalbard, and Greenland, we here discover that Atlantic walrus comprises two monophyletic mitochondrial (MT) clades, which diverged between 23 400 and 251 120 years ago. Our improved genomic resolution allows us to reinterpret the geographical distribution of partial MT data from 306 modern and nineteenth-century specimens, finding that one of these clades was exclusively accessible to Greenlanders. With this discovery, we ascertain the biological origin of 23 archaeological specimens from Europe (most dated between 900 and 1400 CE). These results reveal a significant shift in trade from an early, predominantly eastern source towards a near exclusive representation of Greenland ivory. Our study provides empirical evidence for how this remote Arctic resource was progressively integrated into a medieval pan-European trade network, contributing to both the resilience and vulnerability of Norse Greenland society.This work was supported by the Nansenfondet, the Research Council of Norway projects 262777 and 230821, and the Leverhulme Trust project ‘Northern Journeys’ MRF-2013-065

Molecular dietary analyses of western capercaillies (Tetrao urogallus) reveal a diverse diet

Conservation strategies centered around species habitat protection rely on species’ dietary information. One species at the focal point of conservation efforts is the herbivorous grouse, the western capercaillie (Tetrao urogallus), which is an indicator species for forest biodiversity conservation. Non-molecular means used to study their diet are time-consuming and at low taxonomic resolution. This delays the implementation of conservation strategies including resource protection due to uncertainty about its diet. Thus, limited knowledge on diet is hampering conservation efforts. Here, we use non-invasive environmental DNA (eDNA) metabarcoding on DNA extracted from faces to present the first large-scale molecular dietary analysis of capercaillies. Facal samples were collected from seven populations located in Norway (Finnmark, Troms, Trøndelag, Innlandet) and France (Vosges, Jura, Pyrenees) (n = 172). We detected 122 plant taxa belonging to 46 plant families of which 37.7% of the detected taxa could be identified at species level. The average dietary richness of each sample was 7 ± 5 SD taxa. The most frequently occurring plant groups with the highest relative read abundance (RRA) were trees and dwarf shrubs, in particular, Pinus and Vaccinium myrtillus, respectively. There was a difference in dietary composition (RRA) between samples collected from the different locations (adonis pseudo F5,86 = 11.01, r2 = 0.17, p = 0.001) and seasons (adonis pseudo F2,03 = 0.64, r2 = 0.01, p = 0.036). Dietary composition also differed between sexes at each location (adonis pseudo F1,47 = 2.77, r2 = 0.04, p = 0.024), although not significant for all data combined. In total, 35 taxa (36.8% of taxa recorded) were new capercaillie food items compared with existing knowledge from non-molecular means. The non-invasive molecular dietary analysis applied in this study provides new ecological information of capercaillies’ diet, improving our understanding of adequate habitat required for their conservation

Sexing Viking Age horses from burial and non-burial sites in Iceland using ancient DNA

© 2018 The Authors Horses are the most common grave goods found in Icelandic Viking Age graves. Horse skeletons have previously been sexed based on pelvis shape and the presence of canine teeth in male horses over 4–5 years of age. Morphological data has shown that all horses from Icelandic burials that were amenable to sexing were male. Yet the use of morphological methods to determine sex is problematic since they rely on finding a well-preserved pelvis and/or robust canine teeth. Furthermore, quantitative data underlying the features of the horse pelvis used for sexing is lacking and canine teeth have been reported to occur in mares. In this study we build upon and extend recently developed methodologies to make use of shotgun sequencing of ancient DNA (aDNA) for molecular sexing of Viking Age horse remains. With minimal sequencing effort we identified the sex of the largest collection (n = 22) of Viking Age Icelandic horses studied to date, sourced from both burial (n = 19) and non-burial (n = 3) sites. Our results revealed a male to female sex bias ratio of 18:1 in burial sites, versus 0:3 in non-burial sites. These findings support the significant over-representation of male horses in Viking Age graves in Iceland, yet show that –albeit rare– mares could also be selected for ritual burial in Viking Age Iceland. This cost-effective method provides statistical confidence to allow for sexing of highly fragmented archaeological specimens with low endogenous DNA content
