The application of dialectical behavioural therapy and eco-systemic structural family therapy with children, youth, and families
Kingston Health Sciences Centre is committed to using three family therapy
modalities with their clients at the Child and Youth Mental Health Clinic. Ecosystemic
Structural Family Therapy, Emotion Focused Family Therapy, and Dialectical Behaviour
Therapy are evidenced-based interventions, sometimes used as the sole method of
therapy, but often times as an adjunct to other techniques for children and youth afflicted
with mental health challenges. This thesis is an analysis of the three methods, using the
literature review to provide context, and eliciting examples from three families, that were
counseled throughout a five-month period.Master of Social Work (MSW) Progra
Expressive arts therapy in support groups for bereaved adults in a hospice setting
Expressive Arts Therapies (EXAT) may be seen as a new practice but can be traced back
to the very beginnings of human existence and have been found on all continents and within most
cultures around the world. Since earliest recordings of man, art-making has been used to make
amends, rehabilitate, and transform a person in holistic ways affecting the physical, emotional,
mental, and spiritual aspects of a person leading to health and overall wellbeing. EXAT can
combine the visual arts, movement, drama, music, writing, and other creative processes to foster
deep personal growth and community development. EXAT can also be a guided spiritual journey
and process-oriented intervention with the role of the therapist as the guide into a safe space for
the client to experience integration of the arts. These approaches are convergent with social work
practice, which requires creative problem solving, whereby creativity is used effectively to shape,
mold, influence and uncover unrealized potential in clients. Expressive Arts Therapy also aligns
with social work practice in its theoretical underpinnings, stemming from humanistic, clientcentered perspectives. The advanced practicum described herein involved an 8-week Expressive
Arts course followed by facilitation of two bereavement support groups in hospice using
Expressive Arts Therapy. Some of the Expressive Arts themes explored during the 8-week course
and then implemented within bereavement support groups in hospice included: Introduction to
Expressive Arts; Exploring Relationships; Stories from the Field; Expressive Arts Modalities; Mindful Music and Movement in Expressive Arts; Planning Expressive Arts Experiences;
Professional Issues within Expressive Arts; Sand Tray; and Writing within Expressive Arts.
EXAT can be a very effective therapeutic approach in support of those grieving the death of a
loved one. With the knowledge, skills, and experience I have gained throughout this advanced
practicum, I will be able to confidently incorporate EXAT into my practice when working with
individuals, groups, and communities. Whether supporting bereaved individuals or facilitating bereavement groups, or holding memorial services in the community, EXAT is an effective
process legitimized by evidence-based research, supporting clients as they participate in the
creative process that can lead to positive change and emancipation. Expressive arts can be
integrated into social work as complementary or alternative forms of expression, therapy, and
healing aimed at individual and group change and among many populations in support of a wide
array of issues. In combining art and activism, social workers using expressive arts can draw
public attention to many issues of social concern. Expressive arts also have a place within social
work research, using modalities such as photovoice and performance inquiry.Master of Social Work (MSW) Progra
Fungal community dynamics and carbon mineralization in Populus tremuloides, Picea mariana, and Pinus banksiana coarse woody debris in two ecoregions of northern Ontario
In Canadian silvicultural systems, intensifying biomass removal while harvesting for saw or
pulpwood is presently the only economically feasible way of increasing biomass feedstocks.
As a result, there is less slash and subsequently less coarse woody debris (CWD) pools in
different decay stages over time. The impacts on saproxylic fungi and ecosystem
functioning are not well understood. Fungi are the primary agents of CWD decay in forests,
playing essential roles in nutrient cycling and carbon storage. We compared fungal
biodiversity and CWD mineralization across 3 CWD species (Pinus banksiana, Populus
tremuloides, and Picea mariana), 5 decay classes, and 2 ecoregions representing 3W and 3E
Ontario. Fungal diversity metrics and community structure were examined via high-throughput sequencing of the ITS2 region. CWD pieces were incubated in a temperature controlled lab setting and C mineralization rates measured. Moisture content, density, and nutrient dynamics, including C, N, P, K, Ca, Mg, and Mn concentrations, C:N ratio, and N:P ratio of CWD were assessed. Fungal communities significantly differed among CWD species, decay class, and ecoregion and were primarily correlated with Ca, Mn, and K
concentrations, density, and C:N ratio. Species richness and diversity peaked in 3W Ontario
and in decay classes 4 and 5. We observed a shift from pathogenic, colonizer fungi to an
increased abundance of wood decay fungi as decay class increased. Hardwood CWD had
higher abundances of white rot fungi than softwood CWD. C mineralization was higher in
hardwood CWD, increased with decay class, and was primarily influenced by P
concentration and density. Data from this study will be used in developing forest
management strategies to preserve biodiversity and monitor carbon flux in northern
boreal forests, particularly under intensified-bioenergy production silvicultural systems
A population-based retrospective cohort study of pediatric diabetic ketoacidosis (DKA) hospital admissions in Northern and Southern Ontario: do geography and physician diabetes care matter?
Background: Diabetic Ketoacidosis (DKA), an acute complication of diabetes, is a major cause of death and disability in children with diabetes. The main purpose of this study was to describe the prevalence of DKA hospital admissions in Ontario children with diabetes and examine how it is associated with children’s geographic location and use of physician diabetes care services. The secondary purpose was to describe trends in pediatric diabetes incidence in Northern and Southern Ontario and the entire province
Dynamic stability of the human body during unstable pushups
Instability training provides the nervous system with a greater challenge than traditional
training, and thus can be performed with a reduced external load, potentially reducing the
likelihood of injury. Unstable exercises have also been found to elicit higher levels of core
muscle activity than their stable counterparts and so may increase joint loading. The degree to
which instability challenges the stability of the human body likely relies on the level of
instability of the movement, but the influence of experimental instability, and its effect on the
level of stability of the human body, has yet to be determined. This study aims to examine how
altering the available degrees of freedom of the pushup, as a means of quantifying instability,
may affect the dynamic stability of the lumbar spine. The results of this study indicate that
adding two available degrees of freedom to the conventional pushup significantly increases
kinematic variance of the L1 vertebra through 3-dimensional space. No significant difference in
kinematic variability existed between the two conditions of additional available degrees of
freedom. These results may help health care professionals improve the individualization of their
training programs by taking desired level of instability into account, and adjusting available
degrees of freedom accordingly
La pensée critique en éducation physique et sportive : ce qu’en pensent les futurs enseignants d’EPS de l’ISEPS de Brazzaville en République du Congo
La présente étude a pour but de comprendre la perception des étudiant(e)s en formation initiale à
l’égard de la nature et du rôle de la pensée critique en classe d’EPS. Trente (30) futurs enseignant(e)s en
formation initiale à l’Institut Supérieur d’Éducation Physique et Sportive (ISEPS) en République du Congo ont
répondu à un questionnaire d’une dizaine de questions semi-ouvertes. L’analyse du contenu des réponses a été
faite selon un cadre théorique composé de la conception de la pensée critique de Lipman (1995/2006). Les
résultats révèlent l’existence de plusieurs conceptions de la nature de la pensée critique, tous considérant la
pensée critique comme une habileté cognitive de niveau supérieur au service d’un meilleur apprentissage.
Quant au rôle de la pensée critique, neuf (9) conceptions ont été évoquées, toutes attribuant à la pensée critique une fonction instrumentale en EPS
Deformation history and gold mineralization of the Cadillac Group north of the Larder Lake-Cadillac deformation zone, southern Abitibi greenstone belt, Quebec
The Cadillac Group is located immediately north of the Larder Lake–Cadillac deformation zone
(LLCDZ) along the southern margin of the Abitibi greenstone belt in the Archean Superior
Province, Quebec. The LLCDZ is a major 250 km long structure known for hosting several gold
deposits. It is generally east-trending over a distance of 170 km, and then it swings to the southeast
over a distance of 35 km along the so-called Malartic segment, before resuming its easterly trend
for another 45 km. With its thick sequence of <2687 Ma turbiditic sandstone interlayered with
mudstone and polymictic conglomerate, the Cadillac Group provides favourable rocks for studying
the structural history of the Malartic segment which, due to its unique trend, is important for
understanding the overall tectonic evolution of the LLCDZ. Deformation of the Cadillac Group
began with large-scale isoclinal folding and the formation of a regional cleavage parallel to the
trend of the Malartic segment (D1 event). These structures overprint a 2675.5 ± 2 Ma quartzfeldspar-phyric (QFP) intrusion providing a maximum age for the D1 event and a minimum age for
the deposition of the Cadillac sequence. The deformation of the Cadillac Group resumed with
bedding-parallel sinistral shearing and the emplacement of gold-bearing extensional quartz veins
(D2 event), and continued with bedding-parallel dextral shearing, Z-shaped folding, the formation
of a cleavage oriented oblique (anticlockwise) to the trend of the Malartic segment, and by the
rotation and segmentation of the gold-bearing veins (D3 event). Contrary to previous interpretations
of the Malartic segment as an early pre-D1 accretionary structure, it is interpreted as the short limb
of a broad Z-shaped flexure that formed during D3 folding of the LLCDZ and that postdates the
emplacement of gold-bearing veins in the Cadillac Group. Mineralized veins at the nearby worldclass Canadian Malartic deposit were emplaced during the same D2 event but they differ in
alteration mineralogy and geochemistry to the Cadillac veins suggesting different sources for the
mineralizing fluids. Mineralization at the Lapa deposit is similar in sulphide mineralogy and metal
association to the Cadillac veins but was emplaced earlier during the deformation history of the
LLCDZ
The interaction among hydrogen sulfide, estrogen and insulin-like growth factor-1 in vascular smooth muscle cells
The proliferation of vascular smooth muscle cells (SMCs) is regulated by an array of
endogenous substances, including estrogen, insulin-like growth factor-1 (IGF-1), and hydrogen
sulfide (H2S). Estrogen inhibits SMC proliferation via the activation of estrogen receptor-α (ER-
α), but it stimulates the same in the absence of endogenous H2S. IGF-1, via its receptor (IGF-
1R), stimulates SMC proliferation and migration. ER-α and IGF-1R can form hybrid dimer with
both ER and IGF-1 as the binding ligands. Furthermore, H2S produced by cystathionine-gamma
lyase (CSE) inhibits SMC proliferation. It appears that the interaction and integration of the
vascular effects of estrogen, IGF-1, and H2S determine the outcome of the proliferation of
SMCs. In this thesis study, we found that plasma estrogen levels were significantly lower in
female CSE knockout (KO) mice than in female wide-type (WT) mice. Estrogen treatment of
atherogenic diet-fed mice attenuated hypercholesterolemia, oxidative stress, intracellular
adhesion molecule-1 and NF-κB expression and increased H2S production in WT mice but not in
CSE- KO mice. Not only estrogen and H2S affects each other’s production and function, H2S
also interacts with IGF-1 to inhibit the stimulatory effect of IGF-1 on SMCs proliferation. This
inhibitory effect of H2S was abolished by blocking IGF-1/IGF-1R signaling pathway. On the
other hand, estrogen downregulated the protein expressions of IGF-1 and IGF-1R in mouse
aortic tissues or aortic SMCs. Deficiency of IGF-1R expression or lower IGF-1R activity
abolished the stimulatory effect of estrogen on the proliferation of CSE-KO SMCs. ER-α and
IGF-1R were co-located on cell membrane and co-immunoprecipitated. The binding of estrogen
to IGF-1R/ER-α hybrid catalyzed the stimulatory effect on SMC proliferation. Finally, H2S induced the S-sulfhydration of IGF-1R, but not ER-α, in mouse SMCs, which lead to the
decreased formation of IGF-1R/ER-α hybrid. This decrease inhibited the phosphorylation of
IGF-1R, and attenuated estrogen-induced SMC proliferation.
It is concluded that the antiatherosclerotic effect of estrogen is mediated by CSEgenerated H2S. The absence of H2S favors the interaction of estrogen with IGF-1R/ER-α hybrid
to stimulate SMC proliferation whereas the presence of H2S favors the interaction of estrogen
with ER-α to inhibit SMC proliferation. Our studies demonstrate that H2S reverses the proproliferative effect of estrogen on SMCs and unmasks the dominative anti-atherosclerotic effect
of estrogen. The appreciation of the critical role of H2S in the cardiovascular effects of estrogen
and IGF-1 will help better understand the regulation of the complex vascular effects of estrogen
and sex-related cardiovascular disease
