Global Threats, 2014

In this poll on global and national threats to security and safety, just over half (55%) of Canadians say they aren't confident in the ability of domestic security services to prevent homegrown radicals from carrying out terrorist attacks in Canada.

Baggage Fees, 2014

Canada's major airlines are on the hot seat as a result of recently announced $25 fees for the first checked bag for flights in Canada. This poll shows that Canadian adults are widely opposed to the baggage fees recently imposed by domestic airlines.

Examination of body image among Canadian adolescents: Relations with physical activity and screen time

Background: Adolescence is a period of life associated with self-perceptions of negative body image. Physical activity levels are low and screen time levels are also high during this stage. These perceptions and behaviours are associated with poor health outcomes, making research on their determinants important. With adolescent populations, certain groups may be at higher risk of body dissatisfaction than others, and body dissatisfaction may influence individual physical activity and screen time levels. Objectives: The objectives of this thesis were to: 1) describe body image among young Canadians, examining possible health inequalities 2) estimate the strength and significance of associations between body satisfaction, physical activity and screen time, and 3) examine the potential etiological role of biological sex. Methods: Objective 1: The 2013/2014 Health Behaviour in School-aged Children study was employed. Sex-stratified Rao-Scott chi-square analyses were conducted to examine associations between socio-demographic factors and body satisfaction. Objective 2: The 2005/2006 and 2013/2014 cross-sectional and 2006 longitudinal HBSC data sets were used. Sex-stratified modified Poisson regressions were conducted and risk estimates and associated confidence intervals obtained. Results: Objective 1: Among males, being older, of East and Southeast Asian ethnicity, and reporting low SES all were associated with body dissatisfaction. Among females, being older, of Arab and West Asian or African ethnicity, being born in Canada, and reporting low SES were all associated with being body dissatisfied. Objective 2: Cross-sectionally, males who reported ‘too fat’ body dissatisfaction were more likely to be physically inactive. Adolescents of both sexes who reported ‘too fat’ body dissatisfaction were more likely to engage in high levels of screen time. Data from the longitudinal component supported the idea that male ‘too fat’ body dissatisfaction temporally leads to physical inactivity, but showed an inverse relationship between body dissatisfaction and screen time. Conclusions: Objective 1: Future prevention efforts in Canada should target subgroups to effectively help those at greatest risk of body dissatisfaction, and ameliorate potential inequalities at the population level. Objective 2: The presence of these relationships may inform future interventions as part of a multi-factorial etiology, in order to increase physical activity and decrease screen time among youth.

The Debate on First Nations Education Funding: Mind the Gap (Working Paper 49)

It is at long last becoming part of the public discourse that improving living conditions and opportunities for First Nations communities in Canada is a national imperative. It is also widely recognized that the education is critical to fostering a better future for First Nations people. Yet, for many First Nations youth, particularly those on reserve, completing even high school is well beyond reach. The graduation rate of First Nations people living on reserve was 35.3 per cent as recently as 2011 compared with 78 per cent for the population as a whole. At the same time, the First Nations population is young and growing fast - in First Nations communities 49 per cent of the population is under 24 years of age compared to 30 per cent of the general population. Despite some incremental improvements in education success rates for First Nations students in recent years, the education gap between First Nations and the rest of the country is increasing. The concerns expressed in the 2011 Auditor General report continue to hold weight: "In 2004, we noted that at existing rates, it would take 28 years for First Nations communities to reach the national average. More recent trends suggest that the time needed may still be longer.

Student Financial Aid:The Roles of Loans and Grants (Working Paper 37)

This paper addresses the roles of loans and grants as forms of student financial aid. It begins with a simple choice model where individuals decide to pursue post-secondary studies if i) the net benefits of doing so are positive and ii) no financing or liquidity constraints stand in their way. The effects of loans and grants on these two elements of the schooling decision are then discussed. It is argued that based on equity, efficiency, and fiscal considerations, loans are generally best suited for helping those who want to go but face financing constraints, whereas grants are more appropriate for increasing the incentives for individuals from disadvantaged backgrounds to further their studies. Loan subsidies, which make loans part-loan and part-grant, are also discussed, including how they might be used to address “debt aversion”. Given that subsidised loans have a grant (subsidy) element, while grants help overcome the credit constraints upon which loans are targeted, the paper then attempts to establish some general rules for providing loans, for subsidising the loans awarded, and for giving “pure” grants. It concludes with an application of these principles in the form of a recent proposal for reforming the student financial system in Canada. *

An Ergonomic Evaluation of a Wrist Brace for Canadian Tree Planters

Tree planting is one of the most physically demanding occupations in Canada and as a result, tree planters are at an elevated risk of injury, specifically at the wrist. Wrist injuries develop on account of the highly repetitive nature of the job, as well as other musculoskeletal risk factors including non-neutral wrist postures and high impact forces sustained at the wrist during shovel-ground impact. As a result, wrist brace use has become common among planters, in an effort to limit deviated wrist postures while also providing enhanced stability at the wrist. The external stability provided by a wrist brace is thought to reduce the muscular effort required to provide stiffness at the wrist during shovel-ground impact. Since these prospective benefits have not been formally investigated, the purpose of this study was to determine the effect of a wrist brace on wrist posture, muscle activity, and joint rotational stiffness about the wrist joint (for two degrees of freedom: flexion/extension and ulnar/radial deviation). We hypothesized that the brace would promote more neutrally aligned wrist angles, and that muscle activity and joint rotational stiffness would also decrease when participants wore the brace. Fourteen tree planters with at least one season of experience were recruited to complete two planting conditions in a laboratory setting: one condition while wearing the brace (with brace, WB) and one condition without the brace (no brace, NB). The results from this study showed that at shovel-ground impact muscle activity trended towards increasing in three muscles when participants wore the brace. Additionally, wrist angles improved about the flexion/extension axis of rotation while increasing in deviation about the ulnar/radial axis of rotation when participants wore the brace. Joint rotational stiffness increased when participants wore the wrist brace. Participants from this study indicated difficulty gripping the shovel due to the bulk of the wrist brace, and this feature is discussed with possible suggestions for future iterations of design. In addition to grip diameter this analysis also prompts the suggestion that hand length and experience should also be considered in the design of tree planting tools, specifically an ergonomic aid such as a wrist brace.

Stitching Settler Identities: Canadian Quilts and Their Makers, 1800-1880

Stitching Settler Identities: Canadian Quilts and their Makers, 1800-1880 explores the making, use, and circulation of handmade settler quilts as representation of nineteenth-century women’s social, cultural and economic histories in Canada. An important part of Canadian settlement history is the making and use of handmade quilts in the settler homestead. Handmade coverlets that provided both physical and emotional warmth in the home were a measure of a settler-woman’s careful management of resources and a display of her innovation and creativity. Few settler women recorded their daily experiences; however, most women could sew and quilts offered a method of expression that allowed them to reflect and portray their identities. Thus far, the few studies of quilts have been limited to exhibition catalogues or research that considers a quilt’s aesthetics or its historic significance. While several scholars have called for a reclassification of textile production and needle arts to advance the way in which settler women were viewed as social beings – creating, producing, communicating, and circulating cultural values, most studies on quilts have overlooked a coverlet’s materiality. This study aims to expand the research on quilts as material culture within the context of art history by also considering a quilt’s materiality and when possible, its maker's biography.

RE-MEANING THE SACRED: COLONIAL DAMAGE AND INDIGENOUS COSMOLOGIES

Indigenous ways of knowing are dependent on an inheriting process both amongst humans and between human and non-human being. These multi-relationships cross material and immaterial borders as sites of knowledge production. This manuscript will interrogate how three particular Indigenous cosmological relationships have been purposefully re-meaninged by colonial institutions: 1) How Anishinaabe and Haudenosaunee origin stories have been abstracted into a distinctive epistemological versus ontological site; 2) How Anishnaabe spirit worlds are impacted by colonial relations, and how state institutions benefit from the re-meaning of these worlds; and 3) How Indigenous sovereignty in Canada is imagined from a statist perspective, and how these polices have re-meaninged the sacred relationships within a cosmological understanding of Haudenosaunee governance. The re-meaning of sacredly-held Indigenous relationships is both accelerated by, and contributes to, a practice of reducing upon Indigenous and non-human societies. Throughout expressions of colonialism on Indigenous territories (the academy, the state, Indian policy), Indigenous knowledge is consistently either dismissed or appropriated. This reduction of Indigenous knowledge continues to bolster functions of the state as related to the elimination of the “Indian Problem” via reducing the “Indian” to an adaptive subject.

What is social innovation? The paradigm shift and its relationship with Social Work

Innovation is a fundamental part of social work. In recent years there has been a shift in the innovation paradigm, making it easier to accept this relationship. National and supranational policies aimed at promoting innovation appear to be specifically guided by this idea. To be able to affirm this hypothesis, it is necessary to review the perception that social workers have of their duties. It is also useful to examine particular cases that show how such social innovation arises.

Rethinking Care Through Social Reproduction: Articulating Circuits of Migration

Care has come to dominate much feminist research on globalized migrations and the transfer of labor from the South to the North, while the older concept of reproduction had been pushed into the background but is now becoming the subject of debates on the commodification of care in the household and changes in welfare state policies. This article argues that we could achieve a better understanding of the different modalities and trajectories of care in the reproduction of individuals, families, and communities, both of migrant and nonmigrant populations by articulating the diverse circuits of migration, in particular that of labor and the family. In doing this, I go back to the earlier North American writing on racialized minorities and migrants and stratified social reproduction. I also explore insights from current Asian studies of gendered circuits of migration connecting labor and marriage migrations as well as the notion of global householding that highlights the gender politics of social reproduction operating within and beyond households in institutional and welfare architectures. In contrast to Asia, there has relatively been little exploration in European studies of the articulation of labor and family migrations through the lens of social reproduction. However, connecting the different types of migration enables us to achieve a more complex understanding of care trajectories and their contribution to social reproduction.

Sense making by middlemanagement

Aanleiding voor het onderzoek Deze scriptie sluit aan bij de afstudeerkring “effectieve verandermanagers”. Aanleiding voor dit onderzoek was de brede vraag “Wat onderscheidt een effectieve veranderingsmanager op het middenniveau in organisaties van een minder effectieve bij het implementeren van veranderingen?” Binnen deze brede vraag past de centrale vraagstelling in dit onderzoek: “Welke neerwaartse activiteiten oefenen middenmanagers uit in een sensemakingproces tijdens een verandering?“ Middenmanager Allereerst definiëren we het begrip ‘middenmanager’. De middenmanager bevindt zich op een kruispunt: In de verticale lijn tussen het topmanagement en de werkvloer, op de horizontale lijn tussen de diverse afdelingen (Nonaka,1994). Ten behoeve van mijn onderzoek sluit ik mij aan bij de positionering van Huy (2001). Hij plaatst de middenmanager 2 lagen onder de CEO en 1 laag boven lijnmedewerkers en professionals. In een veranderingsproces heeft de middenmanager verschillende rollen te vervullen. Deze verschillende rollen zijn, onder anderen, beschreven door Huy (2001) en Quinn (1998). Zij noemen: entrepreneur, communicator en therapeut, stimulator, mentor, innovator, bemiddelaar, producent, bestuurder, coördinator, controleur. De onderzoekers zijn het er over eens dat de middenmanager moet balanceren en doseren in de verschillende rollen om effectief te kunnen zijn in een veranderingsproces. Sensemakingproces Dit onderzoek probeert meer kennis te genereren over welke neerwaartse activiteiten middenmanagers uitoefenen gedurende een sensemakingproces tijdens een verandering. We definiëren het begrip ‘sensemakingproces’. Het sensemakingproces vindt plaats als mensen geconfronteerd worden met boodschappen of gebeurtenissen die nieuw zijn. Door met deze nieuwe informatie te kijken naar de bestaande werkelijkheid, is een bewustwording op gang geholpen die kan leiden tot verandering. Er is nog weinig onderzoek gedaan naar de activiteiten (wat doen middenmanagers op dagelijkse basis) van middenmanagers in sensemakingprocessen. Rouleau & Balogun (2007) hebben dat wel onderzocht en onderscheiden de volgende vier sensegivingactiviteiten: het uitrollen van netwerken; het distribueren van gedachten door het voeren van gesprekken; het identificeren van sociale en culturele systemen. Relevantie onderzoek De externe validiteit van het hierboven genoemde onderzoek van Rouleau & Balogun (2007) is echter beperkt, doordat deze is uitgevoerd onder een kleine populatie in Canada en het Verenigd Koninkrijk. Mijn onderzoek wil een bijdrage leveren aan de toename van de externe validiteit door te verifiëren of de neerwaartse activiteiten van de middenmanager die gevonden zijn in het onderzoek van Rouleau & Balogun (2007) middels een andere onderzoeksmethode en met een andere onderzoekspopulatie (de Nederlandse zorginstelling Tactus). Wat betreft de praktische relevantie kan gezegd worden dat mijn onderzoek meer inzicht geeft aan de middenmanagers in welke activiteiten zij uitvoeren of zouden kunnen uitvoeren. Zij kunnen zich bewust worden van hun mogelijkheden om invloed uit te oefenen op het sensemakingproces van hun medewerkers. Ik verwacht daarmee hun effectiviteit te vergroten. Centrale vraag en deelvragen Bij de centrale vraag kunnen de volgende deelvragen geformuleerd worden: 1. Wat is de rol van middenmanagers in een sensemakingproces tijdens een verandering? 2. Zijn de neerwaartse sensemakingactiviteiten van middenmanagers (uit de studie van Rouleau & Balogun, 2007) ook te identificeren zijn binnen één Nederlandse GGZ-stichting? 3. Zijn er andere neerwaartse sensemakingactiviteiten van middenmanagers te identificeren? Conceptuele model Het model dat de basis is voor de beantwoording van de tweede en derde deelvraag, is gebaseerd op de literatuur. In dit model worden de sensemakingactiviteiten van de middenmanager als een onafhankelijke variabele gezien die direct invloed heeft op het sensemakingproces binnen het team. Daarbij kunnen we enkele mediërende en modererende factoren onderscheiden. Als modererende factor noemen we, ten eerste, de mate waarin voor het teamlid het persoonlijke triggerpoint bereikt is. Hoe dichter genaderd, hoe meer kans op verandering bij dit teamlid (Kloosterboer, 2008). Ten tweede noemen we het sneeuwbaleffect van de positieve feedback (Kelman, 2005): hoe verder in het proces, hoe meer kans op verandering. Tenslotte noemen we als modererende factor het emotiemanagement van de middenmanager. Hoe meer de middenmanager in staat is de balans te vinden, hoe meer kans op verandering (Huy, 2002). Als mediërende factor kunnen we de horizontale sensegiving noemen, ofwel de sensegiving door peers (Balogun & Johnson, 2005). Deze sensegiving kan, los van de sensemakingactiviteiten van de manager een geheel eigen verandering op gang brengen. Het kan dus gezien worden als (een deel van) de verklaring voor het sensemakingproces binnen het team. Dit onderzoek beperkt zich tot het bestuderen van de sensemakingactiviteiten van de middenmanager en hun effect op het sensemakingproces binnen het team. In het onderzoek worden de modererende factoren en de mediërende factor dus niet meegenomen. Onderzoeksopzet Het onderzoek is opgesteld als multiple-case design, toetsend onderzoek. Toetsend, omdat de externe validering van de neerwaartse sensemakingactiviteiten van de middenmanager nog laag is. Het multiple-case design biedt de mogelijkheid om cases met elkaar te vergelijken en bredere steun te vinden voor de geformuleerde proposities. De voorgenomen bronnen waren een (één op één) interview met acht middenmanagers, een groepsinterview met meerdere medewerkers per middenmanager en documenten. De focus in alle interviews was de middenmanager en diens sensemakingactiviteiten. De opgevraagde en aangeleverde documenten zijn echter geen adequate bron van informatie gebleken. Resultaten De eerste deelvraag is beantwoord middels literatuurstudie. De onderzoekers zijn het er over eens dat de middenmanager moet balanceren en doseren in de verschillende rollen om effectief te kunnen zijn in een veranderingsproces. De tweede en derde deelvraag werden beantwoord middels een multiple-case design onderzoek. De resultaten uit dit onderzoek laten zien dat de neerwaartse sensemakingactiviteiten uit de studie van Rouleau & Balogun (2007), inderdaad gevonden werden binnen de genoemde GGZ-stichting. De hypothese is daarmee geverifieerd. De derde conclusie is dat er geen andere neerwaartse sensemakingactiviteiten van middenmanagers zijn geïdentificeerd. Door de verkregen informatie over de vier sensemakingactiviteiten van middenmanager terug te brengen naar handelingsniveau, is zichtbaar geworden dat er verschillen zijn tussen de middenmanagers. De handelingen in gezamenlijkheid leidden wel tot de vier sensemakingactiviteiten. Discussie De casestudie heeft geen nieuwe activiteiten aangetoond. Dat maakt de definiëring van het begrip steviger. Door de vier sensemakingactiviteiten (Rouleau & Balogun, 2007) op een derde niveau op te delen in kleinere eenheden, draagt deze casestudie tevens bij aan een nadere definiëring van het begrip ‘neerwaartse sensemakingactiviteiten van de middenmanager’. Door de verduidelijking van het begrip is kwantitatief onderzoek beter mogelijk, waardoor nu ook causale verbanden tussen de neerwaartse sensemakingactiviteiten van de middenmanager en de sensemaking bij de medewerkers gemaakt kunnen worden. Aanbevelingen In een vervolgonderzoek zou het conceptuele model deels of geheel onderzocht kunnen worden. Met een dergelijk onderzoek, of meerdere onderzoeken zou meer duidelijkheid kunnen komen over de mate van invloed van de mediërende factoren en modererende factor op de sensemaking. Aanbeveling voor verder onderzoek is om de onderzoeksmethode te variëren of uit te breiden met bijvoorbeeld participerende observatie. Dan zou waarneming kunnen plaatsvinden vanuit het perspectief van een betrokkene (Yin, 2003). Een andere methode om de activiteiten beter te inventariseren is het laten bijhouden door managers van hun sensemakingactiviteiten. Een bijkomende propositie die dit onderzoek oplevert, is dat de relatie tussen al dan niet hebben van onbewuste kennis en het beschikken over ervaring als leidinggevende niet gelegd kan worden. Deze propositie zou verder onderzocht kunnen worden.

Discovery of relict subglacial lakes and their geometry and mechanism of drainage

Recent proxy measurements reveal that subglacial lakes beneath modern ice sheets periodically store and release large volumes of water, providing an important but poorly understood influence on contemporary ice dynamics and mass balance. This is because direct observations of how lake drainage initiates and proceeds are lacking. Here we present physical evidence of the mechanism and geometry of lake drainage from the discovery of relict subglacial lakes formed during the last glaciation in Canada. These palaeo-subglacial lakes comprised shallow (<10 m) lenses of water perched behind ridges orientated transverse to ice flow. We show that lakes periodically drained through channels incised into bed substrate (canals). Canals sometimes trend into eskers that represent the depositional imprint of the last high-magnitude lake outburst. The subglacial lakes and channels are preserved on top of glacial lineations, indicating long-term re-organization of the subglacial drainage system and coupling to ice flow.
