The article discusses the highlights of the Fifth Annual Conference of the History of Economics Society held in Toronto, Ontario from May 24 to 27, 1978. Papers presented included Newtonian and Darwinian methodologies, historical development of the economics discipline and classical economics. Presentors included Royall Brandis of the University of Illinois, Joseph Remenyi of the Ford Foundation and Claude Menard of the University of Paris.

This paper explores results from a survey of fifty-four trans students in two major universities in Ontario that sought to evaluate participants' access to on-campus facilities. Although both universities have made efforts to accommodate trans students in their use of washrooms, locker rooms, and student housing, the numerous barriers that participants encountered signals stark gaps in access. The results invite a critical reflection of three accommodation models that may be undertaken to address these barriers. By addressing each model's benefits and limitations, wherein the journey towards trans inclusion may generate a new set of exclusions, this paper complicates the notion of increasing access. This paper concludes by offering recommendations across these three models but concedes that challenges may persist until better facilities are reimagined and redesigned going forward.

Despite theoretical accounts asserting the importance of children for the wellbeing of individuals as they age, research evidence suggests that children may be inconsequential when it comes to loneliness. Yet, there is reason to expect some subgroups may be more vulnerable to the impact of childlessness than others and this may also differ depending on the type of loneliness being assessed. This paper addresses the relationship between childlessness and social and emotional loneliness in middle and later life, including differential vulnerability associated with age, gender and marital/partner status. The study drew on data from three waves (2007, 2012 and 2018) of the Canadian General Social Survey for a nationally representative sample of adults aged 45 and older (N = 49,892). In general, childlessness assumed greater importance with regard to social than emotional loneliness. Women reported lower levels of social loneliness in conjunction with childlessness than men. Further, childlessness was associated with higher levels of overall and social loneliness among older than middle-aged adults. Fewer interactions were evident between marital/partner status and childlessness. Among women specifically, those who were co-habiting, separated/divorced or never married reported lower levels of social loneliness than their married counterparts. In contrast, childlessness was linked to greater emotional loneliness only among separated/divorced men and widowed women. Overall, our results suggest that having children available does matter for feelings of loneliness in middle and later life but that the relationship varies and is contingent on the social contexts (age, gender, marital/partner status) and the type of loneliness (social, emotional) involved.

The article focuses on the developments related to Economic History Association (EHA). An announcement is being made by Gary Libecap, 2005/06 EHA President, that the sixty-sixth annual meeting of the EHA will be held in Pittsburgh, Pennsylvania, September 15-17, 2006, at the Omni William Penn Hotel. Nominations are being invited by the Committee on Education of the EHA for the Jonathan Hughes Prize for Excellence in Teaching Economic History. It also highlights the prizes that were awarded at the sixty-fifth annual meeting of the EHA, held in Toronto, Ontario, September 16-18, 2005.

For over half a century, it has been axiomatic that environmental claims are particularly well suited for class actions. This paper examines this notion in the context of Ontario's regime and finds that environmental class actions have been limited in the extent to which they have promoted access to justice. Starting with a brief overview of class action history in Canada and the economics of mass litigation at a general level, the paper then analyzes barriers specific to environmental claims. A series of representative case studies is then offered to substantiate the central contention on the limits of environmental class actions. In so doing, the paper takes a holistic approach, incorporating empirical, economic, political, and procedural factors and dynamics to provide an integrated assessment about the type of access to justice that is presently achieved and achievable for environmental claims in Ontario.

Mandatory meat inspection requirements have long been a source of frustration for advocates of ethical meat. Seen as overly restrictive and ill-adapted to the realities on the ground, some argue that farm-to-consumer sales should be subject to less stringent inspection requirements than conventional meat supply chains. Recently, a series of legislative reforms authorizing on-farm slaughter suggests that policy makers are listening. But do on-farm slaughter exemptions really facilitate ethical meat sales? To answer this question, this paper explores meat inspection systems in Quebec, Ontario, and Vermont. Drawing on data obtained from semi-structured interviews with producers, processors, and policy advisors, it argues that inspection requirements may not be the barriers they are presumed to be. Instead, producers and processors face other more significant financial and structural challenges. These need to be addressed if ethical meat is to be a viable alternative to the dominant model of animal agriculture. [ABSTRACT FROM AUTHOR]

Community trust in law enforcement and confidence in the administration of justice is put to the ultimate test when police officers act outside the limits prescribed by the criminal law. External and civilian oversight of the police can be essential to investigate and respond to allegations of police criminality and impropriety. However, little is known about the investigations completed by civilian oversight agencies and the prosecution of police officers. In this paper, we analyze 159 investigations by the Ontario Special Investigations Unit over a fifteen-year period. We examine each case from the laying of charges to prosecution through to sentencing. We provide an empirical analysis of how the justice system responds to police officers charged with a criminal offence. We situate these findings within the context of the broader justice system and police oversight. At the same time, we observe certain differences between the Canadian and American approaches to dealing with police offenders accused and convicted of criminal offences. [ABSTRACT FROM AUTHOR]

This paper reports on a small-scale study in an elementary school in Southern Ontario, Canada. The study investigated relationships between students' perceptions and practices of gender in popular music education with particular attention given to communication, instruments and technology and development of freedoms and constraints. The findings present a more opaque picture than previous research, suggesting that students frequently transgress binary gendered patterns of practice and perception in this particular field. Gender monoglossia and heteroglossia provide a useful explanatory framework for analysis, indicating that further application of these concepts to issues in popular music education might be most fruitful.

This paper evaluates the sociocultural integration of newcomers, paying special attention to language proficiency while taking into account the importance of the assimilation, cultural fit, and social network perspectives. Analyses are based on administrative data collected by the YMCA of South Western Ontario regarding 2,493 of their clients. Results reveal that newcomers' length of residency, ethnic origin, and social networks play a significant role in the sociocultural integration of newcomers. The longer the newcomers have resided in Canada, the higher their level of sociocultural integration. Non-Europeans displayed a lower level of sociocultural integration than Europeans. However, the most important predictor of sociocultural integration was language proficiency. Not only did language proficiency have a strong and independent effect, but it also tended to level out differences in sociocultural integration of those who had resided in Canada for a short period compared to those living in Canada for a longer period. Similarly, language proficiency decreased sociocultural integration differences between Europeans and ethnic minority newcomers. The policy implications of the results are discussed.

Between 2002 and 2017, Canadian lawmakers sought to redress the pervasive levels of discrimination, harassment, and violence experienced by transgender and/or non-binary people by adding the terms "gender identity" and/or "gender expression" to federal, provincial, and territorial human rights instruments. This paper tracks the complex, iterative ways in which antidiscrimination protections are brought to life outside courts and tribunals. Using Ontario's publicly-funded English language secular school boards as a case study, we examine how the introduction of explicit human rights protections on the basis of "gender identity" and "gender expression" in 2012 worked to produce a series of responses across the education sector. Given that "gender identity" and "gender expression" remain legally undefined terms in the Ontario Human Rights Code, and only provisionally defined by Ontario Human Rights Commission (OHRC) policy, we argue that school boards constitute important actors engaged in constructing the meanings of these terms in policy and practice. In decentering courts and tribunals in our analysis, we aim to uncover the everyday practices of parallel norm-making taking place in the education context. These everyday practices shape how we collectively understand the meaning of "gender identity" and "gender expression." By carefully tracking these post-legislative developments, which rarely make their way into reported decisions, we suggest that human rights law reforms might open up space for the emergence of norms that allow people to do gender in a variety of ways.

Background: Historically transgender adults have experienced barriers in accessing primary care services. In Ontario, Canada, health care for transgender adults is accessed through primary care; however, a limited number of practitioners provide care, and patients are often waiting and/or traveling great distances to receive care. The purpose of this protocol is to understand how primary care is implemented and delivered for transgender adults. The paper presents how the case study method can be applied to explore implementation of health services delivery for the transgender population in primary care. Methods: Case study methodology will be used to explore this phenomenon in different primary care contexts. Normalization Process Theory is used as a guide. Three cases known to provide transgender primary care and represent different Ontario primary care models have been identified. Comparing transgender care implementation and delivery across different models is vital to understanding how care provision to this population can be supported. Qualitative interviews will be conducted. Participants will also complete the NoMAD (NOrmalization MeAsure Development) survey, a tool measuring implementation processes. The tool will be modified to explore the implementation of primary care services for transgender individuals. Documentary evidence will be collected. Cross-case synthesis will be completed to compare the cases. Discussion: Findings will provide an Ontario perspective on the implementation and delivery of primary care for transgender adults in different primary care models. Results may be applicable to other primary care settings in Canada and other nations with similar systems. Barriers and facilitators in delivery and implementation will be identified. Providing an understanding and increasing awareness of the implementation and delivery of primary care may help to reduce the invisibility and disparities transgender individuals experience when accessing primary care services. Understanding delivery of care could allow care providers to implement primary care services for transgender individuals, improving access to health care for this vulnerable population.

ABSTRACTObjective:Compassion fatigue, burnout, and vicarious traumatization are prominent topics in the current literature on the impact of the rewarding but challenging work of healthcare professionals who care for patients with life-limiting illnesses. The positive effects of caregiving constitute a newly emerging outcome that has been relatively unexplored in the pediatric literature, and yet they may play an important role in contributing to the satisfaction and well-being of the healthcare professionals who care for children who have a life-limiting illness.Method: This paper reports the results of a secondary analysis of qualitative interview transcripts that explored the experiences of hospital-based pediatric healthcare providers caring for children with varied life-limiting illnesses. In-depth qualitative interviews were conducted with 25 healthcare professionals (9 social workers, 8 nurses, and 8 physicians). The majority of participants were women (80%), with an age range between 20 and 60 years, and most (84%) had the experience of caring for more than 15 dying children. Thematic analysis was conducted using interpretive description and constant comparison.Results: Every healthcare professional interviewed experienced personal growth as a result of their providing care for dying children. Three dimensions of personal growth were most consistently reported: (1) new or altered life perspectives, (2) enhanced personal resources, and (3) benevolence.Significance Of Results: A deeper understanding of the phenomenon of personal growth could help healthcare organizations to implement innovative approaches that would counterbalance compassion fatigue, and thereby enhance both healthcare provider well-being and child and family outcomes.

This paper presents the results of a sociolinguistic analysis of ne use/non-use in the spoken French of learners of French as a second language enrolled in their first or fourth year of undergraduate studies in a bilingual university in Ontario, Canada. Specifically, it examines the impact of various linguistic and extra-linguistic factors on the students' use of the variants and compares the patterns found to previous research on ne use/non-use among Ontario high school FSL learners and on other sociolinguistic variables in the speech of the same university FSL learners under study here. The paper concludes that while many of the same influences are at work in the speech of both the university and high school learners, the precise influences appear to be modified with continued study and that many of these patterns are similar across variables within the university FSL learners' speech.

This paper explores a grey area of psychiatric practice and, as with other challenging practices, the law is called upon to navigate conflicting legal issues. In particular, this paper explores the covert administration of medication: the concealment of medication in food or drink so that it will be consumed undetected. Rights-based approaches support nuanced understanding of the practices. Few policies, protocols or guidelines govern the practice in Ontario's psychiatric settings. While covert medication is understood to have "something to do" with rights, there is confusion about how those rights play out on the ground. Institutional silences underlie and reinforce the practice. Most pressing, the covert administration of medication warrants an overt discussion, including of its impact on the rights-experience of persons in psychiatric settings. [ABSTRACT FROM AUTHOR]

Following recent work that questions traditional social categories, this paper examines the role of ethnicity in conditioning linguistic variation. Reporting on a large-scale project in the multicultural context of Toronto, we argue for combining emic and etic approaches to social categorization. Focusing on the Chinese and Italian communities, our analysis of two sociolinguistic variables shows that speakers may vary in overall rate, but linguistic conditioning remains largely constant across and within ethnic groups. Whereas there is evidence for language transfer in the first generation, differences between generations suggest that transfer does not persist. Some speakers appear to use overall rates to express ethnic identity. Differences between communities may be explained in terms of different timelines of settlement and visible-minority status.

The Pension Benefits Guarantee Fund (PBGF) was established in the province of Ontario in 1980, thus creating in Canada a rare opportunity for intranational empirical research on the impacts of governmental protection on private plans and their participants. This paper examines Canadian data on pension plans for effects attributable to Ontario's government guarantees for some plans. We find that significant variables related to an increase in the number of pension plans in Canada are higher interest rates, a larger labour market, and, consistent with the deferred compensation theory from labour economics, lower real disposable income of workers. The number of members in pension plans is related significantly to the same variables and also to tax rates and unemployment. The analyses show that the Ontario environment for pension plans is significantly different from the rest of Canada. Those plans covered by the Pension Benefit Guarantee Fund exhibit a lower degree of funding per participant than do the remainder of the plans in the sample, supporting the argument that a government guarantee is related to a moral hazard problem in Ontario pension financing.

This paper examines the politics of urban space through a consideration of three ways Italians in Toronto, Canada, create, make claims to and express their belonging in particular neighbourhoods in the city. The article considers forms of claiming and colonizing space that are not overtly violent or confrontational with respect to other groups living within the plural city but, in effect, are assertions of power over particular places with which others must contend. The three forms encompass a range of scales, temporal duration and purposeful collective expression by Italians in Toronto, and they include the quotidian shaping of neighbourhoods, the calendrical colonizing of public spaces during religious and secular celebrations and the monument building that attests to the permanence of Italians in the city. Ultimately, these forms of place-making must contend with the larger forces of commodification and popular imagery that influence the spatial representations of Italians in Toronto.

This article analyses and compares disability policies for working-age individuals in Canada with a focus on the mode of policy provision and type of measure to determine the degree to which direct funding is used in this country. To consider policy diversity in this federal system, policies are compared using a mixed-methods approach. Using quantitative methods, federal, provincial and territorial policies are first compared using hierarchical cluster analysis. This provides evidence of three distinct clusters in Canada according to policy provision and measure type. In a second, qualitative analysis, the disability strategies of four provinces' (British Columbia, Ontario, Newfoundland and Labrador and Quebec) are compared, to determine over arching policy orientations. Findings indicate that policy provision in Canada largely favours money over services. Furthermore, most provinces emphasize either health or integration measures over substantive measures. Despite these commonalities, significant variation persists across Canada. This extends to poverty and disability reduction strategies with two of the four provinces having a broader orientation while the other two provinces focus specifically on employment as a means of social inclusion. The article concludes with a discussion on the state of employment policies for individuals with a disability in Canada. [ABSTRACT FROM AUTHOR]

Subject dislocation (SD) is common across languages. In French, it is a vernacular norm. In English, it is comparatively rare. This article examines English SD in a unique contrastive situation in Ontario, Canada: two communities where SD is a community norm, one where individuals speak both English and French (Kapuskasing), and the other where the population speaks English only (Parry Sound). Dislocated subjects are produced by the same underlying linguistic mechanisms in both places, with parallel constraints by type of subject and intervening material, suggesting a typological universal. However, SD is age-graded in Kapuskasing, regardless of heritage language. In Parry Sound, it is obsolescent, in steady decline over the twentieth century. We conclude that while typological trends are underlain by universal cognitive processes, locally embedded sociocultural influences are the source of differentiation. [ABSTRACT FROM AUTHOR]

Background: Common postpartum mental health (PMH) disorders such as depression and anxiety are preventable, but determining individual-level risk is difficult. Aims: To create and internally validate a clinical risk index for common PMH disorders. Method: Using population-based health administrative data in Ontario, Canada, comprising sociodemographic, clinical and health service variables easily collectible from hospital birth records, we developed and internally validated a predictive model for common PMH disorders and converted the final model into a risk index. We developed the model in 75% of the cohort (n = 152 362), validating it in the remaining 25% (n = 75 772). Results: The 1-year prevalence of common PMH disorders was 6.0%. Independently associated variables (forming the mnemonic PMH CAREPLAN) that made up the risk index were: (P) prenatal care provider; (M) mental health diagnosis history and medications during pregnancy; (H) psychiatric hospital admissions or emergency department visits; (C) conception type and complications; (A) apprehension of newborn by child services (newborn taken into care); (R) region of maternal origin; (E) extremes of gestational age at birth; (P) primary maternal language; (L) lactation intention; (A) maternal age; (N) number of prenatal visits. In the index (scored 0–39), 1-year common PMH disorder risk ranged from 1.5 to 40.5%. Discrimination (C-statistic) was 0.69 in development and validation samples; the 95% confidence interval of expected risk encompassed observed risk for all scores in development and validation samples, indicating adequate risk index calibration. Conclusions: Individual-level risk of developing a common postpartum mental health disorder can be estimated with data feasibly collectable from birth records. Next steps are external validation and evaluation of various cut-off scores for their utility in guiding postpartum individuals to interventions that reduce their risk of illness.

We propose a statistical procedure to determine the dimension of the nonstationary subspace of cointegrated functional time series taking values in the Hilbert space of square-integrable functions defined on a compact interval. The procedure is based on sequential application of a proposed test for the dimension of the nonstationary subspace. To avoid estimation of the long-run covariance operator, our test is based on a variance ratio-type statistic. We derive the asymptotic null distribution and prove consistency of the test. Monte Carlo simulations show good performance of our test and provide evidence that it outperforms the existing testing procedure. We apply our methodology to three empirical examples: age-specific U.S. employment rates, Australian temperature curves, and Ontario electricity demand. [ABSTRACT FROM AUTHOR]

Although potentially useful for financially hedging systemic weather-related risks, weather contracts/derivatives (also referred to as parametric insurance) have not seen wide adoption in agriculture outside of applications in developing countries, frequently supported by governments and non-governmental organizations (NGOs). A significant impediment is the lack of financial firms willing to stand ready to sell weather derivatives to individual agricultural producers in the over-the-counter market who, due to the localized nature of weather, face idiosyncratic weather-related risks. In particular, the administrative and reinsurance costs of supplying relatively small contracts with specific terms to many different producers are often prohibitive. The current study considers the potential use of weather derivatives in hedging the aggregate yield/revenues of viticulture producers represented by an industry association located in the province of Ontario, Canada. We examine the sensitivity of aggregate industry yields to several relevant weather-related risks employing copula function analysis. We then consider the potential of a weather derivative in hedging the financial risk associated with cold winter temperatures, which pose the greatest risk to aggregate vinifera yields. The issue of attributing costs and payouts to individual association members remains unresolved, and several alternatives are suggested. [ABSTRACT FROM AUTHOR]

Who as a restrictive relativizer in English is an old change from above. In urban dialects, it still acts as a prestige form, whereas it is infrequent or negligible in rural British and American varieties. We compare earlier findings from Toronto, the largest city in the province of Ontario (D'Arcy & Tagliamonte, 2010), with a range of communities from the Ontario Dialects Project (Tagliamonte, 2003–present). While none of the rural locations has as much who as Toronto, there is a substantial range. Regions along the major highways to the north and east of the city have more who , while the smaller towns in less accessible locations have less, consistent with a Cascade Model effect (Labov, 2003). Nonetheless, who shows evidence of diffusion, increasing in apparent time in recent decades. We suggest that this reflects overt pressure from above, consistent with the enduring role that prestige plays in English relativizer variation. [ABSTRACT FROM AUTHOR]

Given the potential environmental and economic sustainability consequences of cover crop adoption, N fertilizer application, and residue management, this study focuses on the yield and financial effects of these on processing tomato production in Ontario, Canada. The study employs financial modeling using field data from a long-term cover crop experiment (oat, cereal rye, radish, and a radish-rye mixture) from 2010 to 2020. Averaged over six experimental years, compared to no cover (87 Mg ha-1) radish (99.6 Mg ha-1) and radish-rye mix (95.2 Mg ha-1) cover crops produce statistically significantly higher tomato yields as isolated practices, increasing farm net returns by $1120 ha-1 and $604 ha-1, respectively. When combined with N application, rye application additionally results in tomato yields statistically significantly higher than the base practice of no cover crop, zero N application and retained residue. Oat cover does not appear to have a statistically significant effect on tomato yields in this dataset. The application of N fertilizer results in statistically significantly higher tomato yield, increasing net returns by $882 ha-1, while residue management does not. [ABSTRACT FROM AUTHOR]

English tense/aspect-marking is an area where variation abounds and where many theories have been formulated. Diachronic studies of the preterit/present perfect alternation indicate that the present perfect (e.g. I have eaten already) has been losing ground to the preterit (e.g. I ate already) (e.g. Elsness 1997, but see Hundt & Smith 2009, Werner 2014). However, few studies have examined this alternation in vernacular speech. This article fills this lacuna by analyzing spoken data from Ontario, Canada, from an apparent-time perspective. Using a large archive of multiple communities and people of different generations, we focus on linguistic contexts known to be variable, viz. with adverbs of indefinite time. Results indicate that, in contrast with previous studies, the alternation is mostly stable. We find evidence of change only with the adverb ever. Where there is evidence of change, this change is different from the predictions in the literature, with the preterit increasing in frequency. We suggest that a minor constructionalization process operates in tandem with ongoing specialization of the preterit/present perfect contrast. Taken together, these results provide another example of the importance of including speech in research on language variation and change and of the unique contribution certain constructions make to more general systems of grammar.

The Niagara Escarpment is a geological feature located in southern Ontario, Canada, and the northeastern United States, comprising highly fractured sandstone, shale and carbonates deposited during the Ordovician and Silurian periods. Differential erosion of the strata has generated a steep cliff face which bisects the city of Hamilton, Ontario. Geological fractures are widespread in the escarpment and result in the formation of unstable blocks of rock subject to erosion through rockfall. This presents structural stability issues of concern due to the proximity of the escarpment to urban infrastructure. We quantify and analyse fracture networks in the escarpment using a combined field- and numerical-modelling-based approach. The location, orientation and aperture of fractures were documented from local outcrops using scanline and area survey methods. Clusters of poles describing the orientation of geological discontinuities were identified in spherical projections, defining three sets: (1) a sub-vertical stratabound set striking N–S, (2) a sub-vertical stratabound set striking E–W, and (3) a set parallel to horizontal sedimentary bedding planes which we infer controlled sub-vertical fracture geometry. Discrete fracture network modelling of fracture sets highlights their high degree of connectivity, and contribution to local geohazards, and quantifies their role in controlling fluid flow through escarpment strata, which is dependent on fracture aperture. Additionally, bedding planes have the potential to act as free surfaces, facilitating stress conditions in which approximately cuboid blocks are produced, and increasing the risk of rockfalls. We conclude that fractures present a first-order control on the fluid-flow properties and stability of the Niagara Escarpment. [ABSTRACT FROM AUTHOR]

Considered in isolation, the radiocarbon (14C) dates on short-lived plant remains from the Jean-Baptiste Lainé (formerly Mantle) site, Ontario, yield an ambiguous result: more or less similar probability around AD 1500 or alternatively around AD 1600. This village site, likely of no more than ca. 20–30 years total duration, illustrates the challenges of high-resolution dating across periods with a reversal/plateau in the 14C calibration curve. Another problem we identify is the tendency for dating probability for short-duration sites to sometimes be overly compressed as dating intensity increases under analysis with OxCal, and for probability to shift away from the real age range especially during reversal/plateau episodes. To address both issues additional constraints are necessary. While a tree-ring sequenced 14C "wiggle-match" is the best option where available, we investigate how, in the absence of such an option, use of the in-built age in wood-charcoal samples can be used to distinguish the likely correct date range. This approach can resolve ambiguities in dating, e.g., for shorter-duration Late Woodland village sites in northeastern North America, but also other short-duration cases corresponding with reversal/plateau episodes on the 14C calibration curve. We place the Jean-Baptiste Lainé site most likely in a range between ca. AD 1595–1626 (95.4% probability). [ABSTRACT FROM AUTHOR]

Objective: To determine the prevalence of human papillomavirus in paediatric tonsils in Southwestern Ontario, Canada. Materials and methods: Patients aged 0–18 years undergoing tonsillectomy were recruited. Two specimens (left and right tonsils) were collected from each participant. Tonsillar DNA was analysed using quantitative polymerase chain reaction to determine the presence of human papillomavirus subtypes 6, 11, 16 or 18. Results: A total of 102 patients, aged 1–18 years (mean age of 5.7 years), were recruited. Ninety-nine surveys were returned. There were 44 females (44.4 per cent) and 55 males (55.6 per cent). Forty patients (40.4 per cent) were firstborn children and 73 (73.7 per cent) were delivered vaginally. Six mothers (6.1 per cent) and one father (1.0 per cent) had prior known human papillomavirus infection, and one mother (1.0 per cent) had a history of cervical cancer. All tonsil specimens were negative for human papillomavirus subtypes 6, 11, 16 and 18. Conclusion: No human papillomavirus subtypes 6, 11, 16 or 18 were found in paediatric tonsil specimens from Southwestern Ontario. [ABSTRACT FROM AUTHOR]

Greenock Swamp wetland complex is one of few remaining natural wetlands in the Great Lakes region and, at 89 km2 in areal extent, is currently the largest hardwood swamp in southern Ontario, Canada. We present here pollen and sediment records from a kettle hole (Schmidt Lake) and adjacent Thuja occidentalis swamp to reconstruct regional paleoclimate and vegetation history, and to assess the timing and development of the swamp ecosystem and associated carbon stocks. Pollen-inferred paleoclimate reconstructions show the expected warming in the Early Holocene, and indicate the Mid-Holocene initiation of lake-effect snow. This enhanced snowfall may have maintained high water tables in the adjacent wetland since ca. 8300 years ago, promoting the establishment of a swamp dominated by Thuja occidentalis. Carbon accumulation rates in a >2-m-long peat core collected from a Thuja occidentalis stand adjacent to Schmidt Lake are 30-40 g C/m2/yr, which is higher than the average of northern high-latitude peatlands. Using topographic and hydrological parameters, we estimated that mean swamp peat thicknesses could exceed 2m. Thus, this study encourages future investigations on temperate swamps from the perspective of hitherto underestimated Holocene carbon sinks and shows the importance of regional hydroclimate in supporting swamp ecosystems.

Pollen and diatom assemblages from well-dated sediment cores from three lakes forming a west-to-east transect across the boreal forest in northwest Ontario (Canada) were used to evaluate the timing and nature of the movement of the prairie-forest ecotone (PFE) across the Holocene. Changes in vegetation, temperature, and effective moisture were inferred from pollen and pollen-based transfer functions. Analyses indicated site-specific vegetational and climate changes across short spatial distances, with prolonged prairie-like conditions during the middle Holocene at the westernmost site. Increased reconstructed temperatures at this westernmost site occurred from ∼9000 to 3000 cal yr BP, alongside increases in diatom-inferred lake levels beginning at ∼6000 cal yr BP. The abundance of Quercus peaked concurrently with rising lake levels before declining to trace levels by ∼3000 cal yr BP. Increases in the abundance of non-arboreal pollen between ∼8500 and ∼4500 cal yr BP at the more eastern lakes suggest relatively delayed and truncated PFE influence, before the reestablishment of primarily boreal taxa by ∼4500 cal yr BP, coincident with diatom-inferred increases in lake levels. This study shows that the PFE moved both farther east and north than previously determined, but generally agrees with established patterns in vegetation from other studied regions along the PFE.

This paper explores processes of settlement aggregation among ancestral Huron-Wendat populations in south-central Ontario, Canada. During the fifteenth century A.D., numerous small communities came together, forming large, fortified village aggregates. In order to understand these processes a multiscalar analytical approach was combined with a conceptual framework emphasizing cross-cultural perspectives on coalescent societies, the archaeology of communities, and historical trajectories of societal change. Regional settlement data are presented to illustrate the movement and increasing size of settlements. In order to determine how individual coalescent communities were formed and maintained, a single village relocation sequence is examined in detail. This sequence illustrates how people constructed, inhabited, and negotiated domestic and public spaces in these new community aggregates. Detailed analyses of the occupational histories of these sites point to the creation of new community-based identities, corporate decision-making structures, and increasing social integration over time. The results of this study demonstrate that while settlement aggregation can be documented at the regional level, only detailed intrasite analyses can identify the small-scale changes in practice that reflect the lived experience of coalescence.

The Crowfield site, excavated in 1981-82, would be a small typical Early Paleoindian campsite except for the added presence of a plough-truncated pit feature containing 182+ burned and destroyed stone artifacts. This paper reports on the latest insights into the feature contents based on continuing attempts to cross-mend fragments, as well as detailed analyses of the spatial distribution of artifact pieces within the feature itself These results reinforce earlier conclusions that the items were burned where found, represent a cache of still functional tools and preforms, and were purposefully destroyed. They confirm that the site represents the best evidence to date for sacred ritual by eastern North American fluted point users. Contrasts with other reported early sacred and secular caches are documented that highlight the uniqueness of the assemblage. It is argued that these contrasts indicate the Crowfield feature assemblage more closely approximates a transported, functioning tool kit, as opposed to the surplus, seasonal and insurance gear or offerings, that dominate other early caches.

International studies show consistently that street-involved or homeless youth have elevated levels of involvement in violence, both as victim and perpetrator. This study recruited equal numbers of male (n=75) and female (n=75) youth, aged 16-20 years, who were accessing service for street-involved youth in Toronto, Canada. This paper examines the correlates of their experiences of violent victimization and perpetration, applying both bivariate and multivariate analyses. We find that because so many of the risk factors for youth violence in general are already concentrated in street youth, it is difficult to identify additional attributes that clearly differentiate the youth who are most likely to be implicated in violence. Some links however were found. Specifically, being male, having a mental health diagnosis, selling drugs and carrying a knife or a gun were associated with victimization, and carrying a knife and selling drugs 50+ times in the past year were significant factors in the more frequent perpetration of violence against others.

Background: Individuals with eating disorders have a high mortality risk. Few population-based studies have estimated this risk in eating disorders other than anorexia nervosa.Aims: To investigate all-cause mortality in a population-based cohort of individuals who received hospital-based care for an eating disorder (anorexia nervosa, bulimia nervosa or eating disorder not otherwise specified) in Ontario, Canada.Method: We conducted a retrospective cohort study of 19 041 individuals with an eating disorder from 1 January 1990 to 31 December 2013 using administrative healthcare data. The outcome of interest was death. Excess mortality was assessed using standardised mortality ratios (SMRs) and potential years of life lost (PYLL). Cox proportional hazards regression models were used to examine sociodemographic and medical comorbidities associated with greater mortality risk.Results: The cohort had 17 108 females (89.9%) and 1933 males (10.1%). The all-cause mortality for the entire cohort was five times higher than expected compared with the Ontario population (SMR = 5.06; 95% CI 4.82-5.30). SMRs were higher for males (SMR = 7.24; 95% CI 6.58-7.96) relative to females (SMR = 4.59; 95% CI 4.34-4.85) overall, and in all age groups in the cohort. For both genders, the cohort PYLL was more than six times higher than the expected PYLL in the Ontario population.Conclusions: Patients with eating disorders diagnosed in hospital settings experience five to seven times higher mortality rates compared with the overall population. There is an urgent need to understand the mortality risk factors to improve health outcomes among individuals with eating disorders. [ABSTRACT FROM AUTHOR]

The Huron-Wendat have had their ancestors' villages and burial sites investigated archaeologically for over 170 years. Past and ongoing land disturbance and invasive archaeological excavation have erased dozens of Huron-Wendat village sites in Ontario, hindering Huron-Wendat duty to care for their ancestors. Consequently, over the last 20 years, in addition to large-scale repatriation of ancestral remains, the Huron-Wendat have requested that archaeologists make every effort to avoid any further excavation of ancestral sites. This poses a new challenge for archaeologists about how to learn about the Huron-Wendat past with minimal disturbance to ancestral sites. Honoring the cultural responsibilities of the Huron-Wendat, the authors have employed minimally invasive remote sensing methods of investigation on Ahatsistari, a forested early seventeenth-century Huron-Wendat village site in Simcoe County, Ontario. Remote sensing methods (e.g., magnetic susceptibility survey, high-resolution soil chemistry sampling, and metal detector survey) have revealed village limits and the possible location and orientation of longhouses, providing essential information in support of the Huron-Wendat imperative to find, assess, and preserve as many of their archaeological sites as possible. This is to protect the ancestors, learn from the ancestors, and preserve ancestral sites and related landscapes for future generations. [ABSTRACT FROM AUTHOR]

Agriculture is a large source of greenhouse gas (GHG) emissions but changing management practices to those more beneficial to the environment could help mitigate climate change as long as they are economically and environmentally viable. This study examines the environmental (public) and economic (private) effects of adopting ten different beneficial management practices on a representative corn farm in Ontario, Canada. The study integrates changes in GHG emissions in carbon equivalents (CO2e) and changes in profit from changes in costs and revenues in two dimensions to reveal the scope and scale of different kinds of practices. 4R nitrogen management practices are smaller in scale compared to cropping practices and, therefore, have smaller potential costs and benefits. Land use changes, from practices including biomass, afforestation, crop rotation and cover cropping, have larger impacts on soil sequestration and carbon-equivalent GHG reduction, but with significantly greater costs. Seven practices were found to, at least partially, be economically and environmentally beneficial. The adoption of no-till and N-rate reduction is firmly positive, whereas the production of biomass has the largest potential economic and environmental gains. Crop rotation and diversification and cover cropping can be mutually beneficial, as can changing N-application practices. The use of inhibitors may be economically beneficial if yield gains outweigh purchase costs. [ABSTRACT FROM AUTHOR]

The article replies to the comment about the authors' paper "Alprazolam and Exposure Alone and Combined in Panic Disorder with Agoraphobia: A Controlled Study in London and Toronto." The authors defend that the subjects in the study were less severely ill than subjects in most drug trials. The study sample may have been more responsive to exposure therapy than more depressed populations.

Objective: To develop and test a tool to assess the price and availability of low-carbon footprint and nutritionally balanced dietary patterns in retail food environments in Ontario, Canada. Design: Availability and price of selected food from discount and regular grocery stores (n 23) in urban/rural areas of northern/southern Ontario were assessed with the Sustainable Nutrition Environment Measures Survey in 2017. Setting: Ontario, Canada. Results: Inter-rater reliability was high for price (intra-class correlation coefficients = 0·819) and for availability (Cohen's κ = 0·993). The tool showed 78 % of the selected food items were available in all stores. Overall, price differences were small between urban and rural locations, and northern and southern Ontario. The greatest price difference was between discount and regular stores. Conclusions: The tool showed excellent inter-rater agreement. Researchers and public health dietitians can use this tool for research, practice and policy to link consumer-level health outcomes to the retail environment. [ABSTRACT FROM AUTHOR]

Background: As life expectancy increases, more people have chronic psychiatric and medical health disorders. Comorbidity may increase the risk of premature mortality, an important challenge for health service delivery. Methods: Population-based cohort study in Ontario, Canada of all 11 246 910 residents aged ⩾16 and <105 on 1 April 2012 and alive on 31 March 2014. Secondary analyses included subjects having common medical disorders in 10 separate cohorts. Exposures were psychiatric morbidity categories identified using aggregated diagnosis groups (ADGs) from Johns Hopkins Adjusted Clinical Groups software® (v10.0); ADG 25: Persistent/Recurrent unstable conditions; e.g. acute schizophrenic episode, major depressive disorder (recurrent episode), ADG 24: Persistent/Recurrent stable conditions; e.g. depressive disorder, paranoid personality disorder, ADG 23: Time-limited/minor conditions; e.g. adjustment reaction with brief depressive reaction. The outcome was all-cause mortality (April 2014–March 2016). Results: Over 2 years' follow-up, there were 188 014 deaths (1.7%). ADG 25 conferred an almost threefold excess mortality after adjustment compared to having no psychiatric morbidity [adjusted hazard ratio 2.94 (95% CI 2.91–2.98, p < 0.0001)]. Adjusted hazard ratios for ADG 24 and ADG 23 were 1.12 (95% CI 1.11–1.14, p < 0.0001) and 1.31 (95% CI 1.26–1.36, p < 0.0001). In all 10 medical disorder cohorts, ADG 25 carried significantly greater mortality risk compared to no psychiatric comorbidity. Conclusions: Psychiatric disorders, particularly those graded persistent/recurrent and unstable, were associated with excess mortality in the whole population, and in the medical disorder cohorts examined. Future research should examine whether service design accounting for psychiatric disorder comorbidity improves outcomes across the spectrum of medical disorders. [ABSTRACT FROM AUTHOR]

Aims: Social determinants of health have the potential to influence mental health and addictions-related emergency department (ED) visits and the likelihood of admission to hospital. We aimed to determine how social determinants of health, individually and in combination, relate to the likelihood of hospital admission at the time of postpartum psychiatric ED visits. Methods: Among 10 702 postpartum individuals (female based on health card) presenting to the ED for a psychiatric reason in Ontario, Canada (2008–2017), we evaluated the relation between six social determinants of health (age, neighbourhood quintile [Q, Q1 = lowest, Q5 = highest], rurality, immigrant category, Chinese or South Asian ethnicity and neighbourhood ethnic diversity) and the likelihood of hospital admission from the ED. Poisson regression models generated relative risks (RR, 95% CI) of admission for each social determinant, crude and adjusted for clinical severity (diagnosis and acuity) and other potential confounders. Generalised estimating equations were used to explore additive interaction to understand whether the likelihood of admission depended on intersections of social determinants of health. Results: In total, 16.0% (n = 1715) were admitted to hospital from the ED. Being young (age 19 or less v. 40 or more: RR 0.60, 95% CI 0.45–0.82), rural-dwelling (v. urban-dwelling: RR 0.75, 95% CI 0.62–0.91) and low-income (Q1 v. Q5: RR 0.81, 95% CI 0.66–0.98) were each associated with a lower likelihood of admission. Being an immigrant (non-refugee immigrant v. Canadian-born/long-term resident: RR 1.29, 95% CI 1.06–1.56), of Chinese ethnicity (v. non-Chinese/South Asian ethnicity: RR 1.88, 95% CI 1.42–2.49); and living in the most v. least ethnically diverse neighbourhoods (RR 1.24, 95% CI 1.01–1.53) were associated with a higher likelihood of admission. Only Chinese ethnicity remained significant in the fully-adjusted model (aRR 1.49, 95% CI 1.24–1.80). Additive interactions were non-significant. Conclusions: For the most part, whether a postpartum ED visit resulted in admission from the ED depended primarily on the clinical severity of presentation, not on individual or intersecting social determinants of health. Being of Chinese ethnicity did increase the likelihood of admission independent of clinical severity and other measured factors; the reasons for this warrant further exploration.

Aims: There is currently no universally accepted measure for population-based surveillance of mood and anxiety disorders. As such, the use of multiple linked measures could provide a more accurate estimate of population prevalence. Our primary objective was to apply Bayesian methods to two commonly employed population measures of mood and anxiety disorders to make inferences regarding the population prevalence and measurement properties of a combined measure. Methods: We used data from the 2012 Canadian Community Health Survey – Mental Health linked to health administrative databases in Ontario, Canada. Structured interview diagnoses were obtained from the survey, and health administrative diagnoses were identified using a standardised algorithm. These two prevalence estimates, in addition to data on the concordance between these measures and prior estimates of their psychometric properties, were used to inform our combined estimate. The marginal posterior densities of all parameters were estimated using Hamiltonian Monte Carlo (HMC), a Markov Chain Monte Carlo technique. Summaries of posterior distributions, including the means and 95% equally tailed posterior credible intervals, were used for interpretation of the results. Results: The combined prevalence mean was 8.6%, with a credible interval of 6.8–10.6%. This combined estimate sits between Bayesian-derived prevalence estimates from administrative data-derived diagnoses (mean = 7.4%) and the survey-derived diagnoses (mean = 13.9%). The results of our sensitivity analysis suggest that varying the specificity of the survey-derived measure has an appreciable impact on the combined posterior prevalence estimate. Our combined posterior prevalence estimate remained stable when varying other prior information. We detected no problematic HMC behaviour, and our posterior predictive checks suggest that our model can reliably recreate our data. Conclusions: Accurate population-based estimates of disease are the cornerstone of health service planning and resource allocation. As a greater number of linked population data sources become available, so too does the opportunity for researchers to fully capitalise on the data. The true population prevalence of mood and anxiety disorders may reside between estimates obtained from survey data and health administrative data. We have demonstrated how the use of Bayesian approaches may provide a more informed and accurate estimate of mood and anxiety disorders in the population. This work provides a blueprint for future population-based estimates of disease using linked health data. [ABSTRACT FROM AUTHOR]

Objective: Quality end-of-life (EOL) care is critical for dying residents and their family/friend caregivers. While best practices to support resident comfort at EOL in long-term care (LTC) homes are emerging, research rarely explores if and how the type of care received at EOL may contribute to caregivers' perceptions of a good death. To address this gap, this study explored how care practices at EOL contributed to caregivers' perceptions of a good resident death.Method: This study used a retrospective cross-sectional survey design. Seventy-eight participants whose relative or friend died in one of five LTC homes in Canada completed self-administered questionnaires on their perceptions of EOL care and perceptions of a good resident death.Results: Overall, caregivers reported positive experiences with EOL care and perceived residents to have died a good death. However, communication regarding what to expect in the final days of life and attention to spiritual issues were often missing components of care. Further, when explored alongside direct resident care, family support, and rooming conditions, staff communication was the only aspect of EOL care significantly associated with caregivers' perceptions of a good resident death.Significance Of Results: The findings of this study suggest that the critical role staff in LTC play in supporting caregivers' perceptions of a good resident death. By keeping caregivers informed about expectations at the very end of life, staff can enhance caregivers' perceptions of a good resident death. Further, by addressing spiritual issues staff may improve caregivers' perceptions that residents were at peace when they died. [ABSTRACT FROM AUTHOR]
