description: Emotional and behavioral (EB) problems in children are associated with increased perceptions of strain in parenting. Among children receiving services, parenting stress has been linked to initiating services for their children, and may strain the relationship between parent and child. In contrast, parental engagement and empowerment in services is an important quality indicator for positive treatment outcomes. However, no known studies have examined the association between parent empowerment in their child’s services and their perceptions of stress related to parenting a child with significant mental health needs. Further, no studies have explored whether empowerment moderates the relationship between the child’s symptoms and parental perceptions of stress. The current study examined the impact of child EB problems and parent empowerment on parenting stress. Among a sample of 525 parents of children receiving school-based services for disruptive behavior disorders, child EB problems significantly predicted parenting stress. Parent empowerment also correlated with lower parenting stress, as hypothesized. Although parent empowerment was not found to moderate the relationship between child symptomatology and parenting stress, the relationship between parent empowerment and parenting stress differed based on child gender and age. Parent empowerment was associated with lower parenting stress more for parents of females and younger children than for parents of males and older children.

description: The forest tent caterpillar (Malacosoma disstria Hubner) is a serious economic pest of many deciduous trees throughout North America. This insect avoids the foliage of red maple (Acer rubrum L.). An investigation of the phytochemical activity of the foliage of A. rubrum against the forest tent caterpillar (FTC) was undertaken. It was discovered that the foliage of sugar maple (Acer saccharum Marsh.), generally considered to be a food host of the FTC, could also contain secondary chemicals that harm this insect. When fed foliage of both maples, the FTC grew at a significantly reduced rate than those larvae that were fed the foliage of the preferred host, trembling aspen (Populus tremuloides Michx). All larvae fed red maple were dead within two weeks. The primary mode of action of sugar maple was one of internal toxicity (growth inhibition) whereas red maple was severely antifeedant and possibly also internally toxic. Feeding bioassays with extracts and purified compounds from the maples incorporated into artificial diet at sub-ecological levels, revealed that both species are chronically toxic and cause concentration-dependent reductions in larval growth and pupal weight, and increases in larval mortality. An increase in the time needed to reach pupation and adulthood for males in the red maple treatment was also observed. The extract of A. saccharum leaves was actually more active against the forest tent caterpillar than was the species of maple that the insect always avoided. A study of the variability of the maple defensive phytochemicals showed that although some variation in anti-FTC activity between different growing sites and within individual trees from the same growing site existed, it was not great enough to support the hypothesis that certain sugar maple trees possessed relatively lesser phytochemical defenses.

Expression and transient nuclear translocation of protein convertase 1 (PC1) during mouse preimplantation embryonic development
Creators: name: St. Germain, Carly
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2004
Subjects: subject: Chemistry, Biochemistry.

description: Preimplantation embryos express a number of hormones, neuropeptides and membrane receptors known to derive from proteolytic activation of their precursors by proprotein convertases (PCs). The goal of this study was to determine the pattern of expression of the neuroendocrine protein convertase 1 (PC1) in mouse preimplantation embryos. Previous data have shown that PC1 transcripts are detectable by reverse transcription-polymerase chain reaction in unfertilized and fertilized eggs as well as at all stages of preimplantation embryonic development (Croissandeau and Mbikay, unpublished data). In this study, we show by immunoblotting that the zymogen and mature forms of PC1 are present at these stages. Using immunofluorescence laser confocal microscopy, we have examined its subcellular location: PC1-specific staining was observed throughout the cytoplasm of unfertilized eggs. After fertilization, surprisingly, the staining was transiently concentrated in pronuclei. It relocated to the cytoplasm at post-zygotic stages and was particularly strong at junctions between blastomeres. The nuclear translocation of PC1 in fertilized eggs is probably mediated by its prodomain. Indeed, when transfected in human colon carcinoma LoVo cells, a mutant proPC1 incapable of cleaving off its prodomain accumulated in the nucleus. Furthermore, when N-terminally fused to a green fluorescent protein, this domain was able to direct the reporter protein to the nucleus of these cells. Collectively, these data suggest that PC1 is a potential convertase for precursor proteins in preimplantation embryos. They also raise the possibility of a nuclear function for this enzyme during zygote formation.
What sovereign rights for Indigenous Australians?
Creators: name: McAllan, Fiona
Publisher: name: Swinburne
Year: 2024

description: While the Australian settler population voted to include Indigenous peoples as citizens in their own country in 1967, this citizenship has remained on assimilative terms. Indigenous sovereignty, which would fundamentally allow for Indigenous cultural, educational, linguistic and law systems, has not been properly acknowledged either pedagogically, legislatively or ideologically in Australia. Until co-sovereignty is recognised as taking place within a relational ontology constitutively, and epistimologically supported as such, Indigenous peoples will remain the country's most disadvantaged citizens. This will be the case both in Australia, and in other colonised territories and globalisation will only exacerbate these effects. I will argue that relational ontologies of Indigenous and poststructural theorists show that co-sovereignty requires the allowance for difference as its structuring principle.

description: OBJECTIVE: The objective of this study was to compare the dual-energy computed tomography (CT) characteristics of parathyroid adenomas (PAs), thyroid tissue, and lymph nodes (LNs) and assess whether the spectral information can improve distinction of these tissues.
METHODS: Dual-energy CT scans from 20 patients with pathologically proven PAs were retrospectively evaluated, identifying 19 eligible PAs and region of interest analysis used for spectral characterization.
RESULTS: There was a significant difference in multiple spectral parameters between PAs, LNs, and the thyroid gland (P < 0.05-0.0001). The greatest difference in spectral characteristics of PAs compared with that of LNs was on the 25-second acquisition, whereas the 55-second acquisition was better for distinguishing PAs from the thyroid gland.
CONCLUSIONS: Four-dimensional CT acquired in dual-energy CT mode has the potential to further enhance diagnostic accuracy for PA identification on individual phases of the perfusion study.
Practicing in and learning from community placements

description: In 2004, the authors began a qualitative study into the value of community placements as sites of sociocultural and sociolinguistic learning among English as an Additional Language (EAL) learners studying a Bachelor of Arts degree. Students undertook community placements of ten hours, and wrote reflective journals detailing their observations of and participation in social, cultural and linguistic interactions. This paper reports on the key findings of the project over the past three years. It also applies the notion of 'community of practice' (Lave and Wenger, 1991) to community placement within a framework that accommodates constructivist, sociocultural, poststructuralist and new literacy understandings of situated learning. This report discusses participant commentaries in terms of the ten most recurrent themes emerging from open-coded analyses of the data. The findings suggest that community placement has the capacity to provide significant experiences for students, and to impact on participants' evolving identities as bi- or multiculturals. Community placements also provide opportunities for acquiring procedural, pragmatic and linguistic knowledge. The paper concludes that community placements can serve as communities of practice for the majority of language and cultural learners.

Subjects: subject: Engineering, Chemical.

description: In this study methyl chloride was selected as the main adsorbate since it is one of the volatile organic compounds produced largely in industry. Nitrogen was the other adsorbate since air is composed of nitrogen by 79%. As adsorbents one in-house adsorbent; SBA-15 and three commercial adsorbents; HiSiv-3000 (ZSM-5 zeolite), activated carbon cloth, mesoporous activated carbon were used. Experiments of constant volume technique were performed in order to obtain adsorption isotherms of methyl chloride and nitrogen with the adsorbents mentioned above up to 1.6 arm in the temperature range of 21.5 and 80°C. Langmuir, Freundlich, Sips and Toth isotherm models were fitted to these isotherms. By using the Toth isotherm parameters adsorption isosteres were obtained. Henry's Law constants and heat of adsorption values were calculated. Expected working capacities for pressure swing adsorption (PSA), vacuum swing adsorption (VSA), temperature swing adsorption (TSA) were obtained and feasibility of these processes was discussed. The binary system behavior was also predicted for HiSiv-3000 and SBA-15 by using Extended Langmuir and Ideal Adsorbed Solution models. Methyl chloride adsorption breakthrough curves with HiSiv-3000 and SBA-15 for vacuum swing adsorption application was produced. The effects of modeling parameters such as temperature, inlet concentration, flow rate and bed length were investigated. It was concluded that mesocarbon is the best adsorbent to separate methyl chloride from air. Carbon cloth has the lowest heat of adsorption for methyl chloride. Prediction of binary system behavior showed that nitrogen adsorption is negligible. Mesocarbon shows the highest expected working capacities for PSA, VSA and TSA. VSA and TSA were found to be two promising processes for separation of methyl chloride from air. (Abstract shortened by UMI.)

description: This case study describes 1 year of the psychoanalytic psychotherapy using clinical data, a standardized instrument of the psychotherapeutic process (Psychotherapy process Q-Set, PQS), and functional neuroimaging (fMRI). A female dysthymic patient with narcissistic traits was assessed at monthly intervals (12 sessions). In the fMRI scans, which took place immediately after therapy hours, the patient looked at pictures of attachment-relevant scenes (from the Adult Attachment Projective Picture System, AAP) divided into two groups: those accompanied by a neutral description, and those accompanied by a description tailored to core conflicts of the patient as assessed in the AAP. Clinically, this patient presented defense mechanisms that influenced the relationship with the therapist and that was characterized by fluctuations of mood that lasted whole days, following a pattern that remained stable during the year of the study. The two modes of functioning associated with the mood shifts strongly affected the interaction with the therapist, whose quality varied accordingly (“easy” and “difficult” hours). The PQS analysis showed the association of “easy” hours with the topic of the involvement in significant relationships and of “difficult hours” with self-distancing, a defensive maneuver common in narcissistic personality structures. In the fMRI data, the modes of functioning visible in the therapy hours were significantly associated with modulation of the signal elicited by personalized attachment-related scenes in the posterior cingulate (p = 0.017 cluster-level, whole-volume corrected). This region has been associated in previous studies to self-distancing from negatively valenced pictures presented during the scan. The present study may provide evidence of the possible involvement of this brain area in spontaneously enacted self-distancing defensive strategies, which may be of relevance in resistant reactions in the course of a psychoanalytic psychotherapy.
Is it my cancer or am i just getting older?: Impact of cancer on age‐related health conditions of older cancer survivors

description: BACKGROUND: The extent to which cancer exacerbates or creates new health conditions is a long-standing, unanswered question. The current prospective study examined the short-term impact of cancer on the functioning, development of, and worsening of age-related health conditions among older adults who develop cancer compared with age-matched controls.
METHODS: Surveillance, Epidemiology, and End Results registry data were linked with Medicare Health Outcomes Survey (MHOS) data. A total of 921 eligible cases were Medicare beneficiaries with diagnosis of breast, colorectal, lung, or prostate cancer made between their baseline and follow-up MHOS. Using propensity score matching, 4605 controls without cancer were matched from the MHOS. Analysis of covariance and logistic regression were used to examine changes in physical functioning, activities of daily living, age-related conditions, and exacerbation of preexisting conditions for cases compared with controls.
RESULTS: Cancer groups demonstrated greater declines in activities of daily living and physical function compared with controls (mean, -1.53 [standard error, 0.14]), with the greatest change noted for patients with lung cancer (mean, -6.72 [standard error, 0.94]). Having a cancer diagnosis increased the risk of depression but did not increase the odds of developing arthritis in the hand and/or hip, urinary incontinence (except for prostate cancer), or vision and/or hearing problems. Having a cancer diagnosis also did not exacerbate the severity of arthritis or foot neuropathy.
CONCLUSIONS: The findings of the current study suggest that cancer is a stronger driver for declines in physical functioning and an increased risk of depression in older adults. Interventions are needed to decrease these risks. Clinicians need to prepare patients and families for changes in functioning levels and interventions that limit the declines for older patients with cancer are needed.

Subjects: subject: Chemistry, Inorganic.

description: This work was launched to study the chemistry of disubstituted 1,8-diaminonaphthalene (R2DAN) as a supporting framework for carbene centers, high oxidation state early transition metals and lanthanide centers. R2DAN ligands are dianionic bidentate groups making them good candidates to stabilize high oxidation state complexes. This work focuses on the preparation of early transition metal (Ti, Zr, Hf, Ta, W) and lanthanide complexes. This framework for the preparation of bridging carbenes is also presented. Chapter 1 gives an introduction on ligands found in the literatutre and the importance on amido ligands in catalysis. The second chapter focusses on the use of the disubstituted 1, 8-damiononaphthalene framework in the preparation of bridging carbenes. A dimerization study of a mono carbene is also presented. The third chapter explores the use of the R2DAN ligand to support lanthanide centers. The synthesis of these species and their structural features these complexes are discussed. In the fourth chapter the preparation of group IV complexes bearing R2DAN ligands is presented. A few different approaches to introduce the ligand to a metal centers are outlined and discussed. The influence of the nitrogen substituent on the structure of the complexes is also disscused. Chapter 5 presents the synthesis of tantalum complexes bearing R2DAN ligands along with a structural study of these compounds. A computational study of the structural features of these complexes is presented. The last section of chapter 5 describes the reactivity of the tantalum complexes towards LiNMe2 and MeLi. In Chapter 6 the synthesis of tungsten bis(imido) complexes bearing R2DAN ligands is presented. The fold of the ligands in these complexes is explored using computational chemistry. The reactivity of the tungsten complexes with heterocumelenes and trimethyl aluminum is discussed. The final section of chapter 6 shows the potential of the tungsten complexes as catalysts for cyclotrimerization of isocyanates. Chapter 7 summarizes the work presented in this thesis.
Dyadic empathy and romantic attachment: Explaining psychological and physical intimate partner violence in heterosexual couples

description: Empathy is a prominent component of social competence and is believed to foster effective communication, promote successful conflict management, and improve social relationships quality (Davis, 1994). The role of empathic responses in the romantic context, however, was overlooked in past literature, hence limiting our understanding of its contribution to global marital functioning. Dyadic empathy is the focus of this thesis and is examined through two articles. The first article is concerned with the measurement of dyadic empathy. The Interpersonal Reactivity Index (Davis, 1980), a measure of general cognitive and emotional empathy, was adapted to assess empathy expressed toward the partner specifically and was validated in three independent samples of romantically involved individuals and couples. Confirmatory factor analyses yielded a two-factor structure (dyadic perspective taking and dyadic empathic concern), statistically invariant across gender and relationship type (heterosexual versus same-sex). Evidence of convergent, discriminant, concurrent, predictive, and incremental validity, as well as reliability and stability of the Interpersonal Reactivity Index for Couples is also provided. In sum, this measure appears valid for the assessment of cognitive and emotional dyadic empathy in diverse types of couples. The second article presents a theoretical model in which dyadic empathy mediates the relationship between romantic attachment and psychological and physical intimate violence. Attachment was assessed through self-report and behavioural observation in 193 couples recruited in the general community. Results from multilevel analyses generally support the theory. Attachment anxiety and avoidance negatively predicted dyadic empathy and positively predicted intimate partner violence in both men and women. Dyadic empathy in partners also predicted psychological and physical partner violence. Dyadic empathy mediated the relationship between avoidance and the use of psychological violence in women. Contrary to predictions, however, behaviourally observed attachment was unrelated to dyadic empathy or partner violence. This study has clinical implications and suggests that both romantic attachment and empathy expressed toward the partner may be valuable points of intervention for understanding and preventing the occurrence of violence within intimate relationships.

description: Neuropathological studies revealed the propagation of amyotrophic lateral sclerosis (ALS) in a sequence of four separate disease-related regional patterns. Diffusion tensor imaging (DTI)-based analysis was established for the individual mapping of sequential disease spreading in ALS as the in vivo transfer to neuroimaging. The aim of this review is to summarize cross-sectional and longitudinal results of these technical approaches in ALS as an in vivo tool to image ALS propagation stages. This concept was also applied to restricted phenotypes of ALS, e.g., lower motor neuron disease (LMND) or primary lateral sclerosis (PLS). In summary, the regional disease patterns in the course of ALS have been successfully mapped by DTI in vivo both cross-sectionally and longitudinally so that this technique might have the potential as a read-out in clinical trials.

Deux positions angulaires du genou et deux deplacements de la projection de la ligne de gravite (faits a partir de l'articulation de la cheville) sont analyses. La posture debout naturelle (telle que choisie par le sujet) a ete utilisee comme posture temoin et facteur de normalisation. Le deplacement de la ligne de gravite a ete mesuree par rapport a la colonne lombaire (niveau L$\sb3$) et aux membres inferieurs. Les resultats de cette etude permettent d'arriver aux conclusions suivantes: (1) Pour les postures debout qui ont ete analysees, l'EMGN des muscles para-vertebraux lombaires diminue dans la mesure ou l'ecart entre L$\sb3$ et la PCG augmente. (2) Dans une posture debout avec les genoux en hyperextension et la PCG tombant devant les malleoles externes, l'EMGN des muscles para-vertebraux lombaires est plus grande que l'EMGN dans une posture semblable avec la PCG tombant sur les malleoles externes. Elle est aussi plus grande dans une position debout avec les genoux flechis, la PCG tombant soit sur les malleoles externes, soit devant les malleoles externes. (3) Dans la posture debout avec les genoux flechis a dix degres, l'EMGN des para-vertebraux lombaires et la distance sagittale entre L$\sb3$ et la PCG ont tendance a etre semblables a celles trouvees dans une posture debout naturelle. (4) Les deplacements sagittaux de la cheville ont une influence sur le role antigravitaire des muscles tibial anterieur et droit anterieur. (Abstract shortened by UMI.)

description: This study examined differences in food and beverage intake estimated from nationally representative surveys of Canadians in 2004 and 2015 collected through the Canadian Community Health Surveys. Differences in mean daily energy intake and amounts of food consumed were compared between 2004 and 2015 and across age groups for all energy reporters (aged 2 years+) and among only plausible energy reporters. From 2004 to 2015, mean energy intake decreased by 228 kcal/day (all energy reporters) and 74 kcal/day (plausible energy reporters). Canadians reported consuming more daily servings of meat and alternatives but fewer servings of vegetables and fruit and milk and alternatives in 2015 compared to 2004. Analyses of food subgroups revealed that Canadians reported consuming more daily servings of dark green and orange vegetables, dairy products, legumes, nuts and seeds, and eggs but fewer servings of potatoes, other vegetables, fruit juices, fluid milk, and sugar-sweetened beverages in 2015 compared to 2004. While some aspects of the Canadian diet have improved, daily mean intake of other nutritious foods either stagnated or worsened over time. Continued attention is needed to improve population-level intakes of vegetables, fruit, whole grains, and protein foods such as legumes, nuts, seeds, and lower fat dairy products.

description: BackgroundThe reported incidence (0.16–1.5 %) of bile duct injury (BDI) during laparoscopic cholecystectomy (LC) is higher than during open cholecystectomy and has not decreased over time despite increasing experience with the procedure. The “critical view of safety” (CVS) technique may help to prevent BDI when certain criteria are met prior to division of any structures. This study aimed to evaluate the adherence of practicing surgeons to the CVS criteria during LC and the impact of a training intervention on CVS identification.MethodsLC procedures of general surgeons were video-recorded. De-identified recordings were reviewed by a blinded observer and rated on a 6-point scale using the previously published CVS criteria. A coaching program was conducted, and participating surgeons were re-assessed in the same manner.ResultsThe observer assessed ten LC videos, each involving a different surgeon. The CVS was adequately achieved by two surgeons (20 %). The remaining eight surgeons (80 %) did not obtain adequate CVS prior to division of any structures, despite two surgeons dictating that they did; the mean score of this group was 1.75. After training, five participating surgeons (50 %) scored > 4, and the mean increased from 1.75 (baseline) to 3.75 (p < 0.05).ConclusionsThe CVS criteria were not routinely used by the majority of participating surgeons. Further, one-fourth of those who claimed to obtain the CVS did so inadequately. All surgeons who participated in training showed improvement during their post-assessment. Our findings suggest that education of practicing surgeons in the application of the CVS during LC can result in increased implementation and quality of the CVS. Pending studies with larger samples, our findings may partly explain the sustained BDI incidence despite increased experience with LC. Our study also supports the value of direct observation of surgical practices and subsequent training for quality improvement.

description: Background and Purpose: Clinical outcome and mortality after endovascular thrombectomy (EVT) in patients with ischemic stroke are commonly assessed after 3 months. In patients with acute kidney injury (AKI), unfavorable results for 3-month mortality have been reported. However, data on the in-hospital mortality after EVT in this population are sparse. In the present study, we assessed whether AKI impacts in-hospital and 3-month mortality in patients undergoing EVT. Materials and Methods: From a prospectively recruiting database, consecutive acute ischemic stroke patients receiving EVT between 2010 and 2018 due to acute large vessel occlusion were included. Post-contrast AKI (PC-AKI) was defined as an increase of baseline creatinine of ≥0.5 mg/dL or >25% within 48 h after the first measurement at admission. Adjusting for potential confounders, associations between PC-AKI and mortality after stroke were tested in univariate and multivariate logistic regression models. Results: One thousand one hundred sixty-nine patients were included; 166 of them (14.2%) died during the acute hospital stay. Criteria for PC-AKI were met by 29 patients (2.5%). Presence of PC-AKI was associated with a significantly higher risk of in-hospital mortality in multivariate analysis [odds ratio (OR) = 2.87, 95% confidence interval (CI) = 1.16–7.13, p = 0.023]. Furthermore, factors associated with in-hospital mortality encompassed higher age (OR = 1.03, 95% CI = 1.01–1.04, p = 0.002), stroke severity (OR = 1.05, 95% CI = 1.03–1.08, p < 0.001), symptomatic intracerebral hemorrhage (OR = 3.20, 95% CI = 1.69–6.04, p < 0.001), posterior circulation stroke (OR = 2.85, 95% CI = 1.72–4.71, p < 0.001), and failed recanalization (OR = 2.00, 95% CI = 1.35–3.00, p = 0.001). Conclusion: PC-AKI is rare after EVT but represents an important risk factor for in-hospital mortality and for mortality within 3 months after hospital discharge. Preventing PC-AKI after EVT may represent an important and potentially lifesaving effort in future daily clinical practice.
Entrepreneurial strategic orientation and export performance of Thai small and medium-sized enterprises

Publisher: name: Swinburne
Year: 2024

description: This study investigates in the context of Thailand the relationship between a key but most disputed entrepreneurship concept, i.e. entrepreneurial strategic orientation (EO), and business performance of exporting small and medium-sized enterprises (SMEs). The study followed a contingency approach in examining the existence of the EO concept, its association with performance, as well as the influences of contingency variables critical to the study context. The study is hypothetical-quantitative and explanatory in nature. A paper-based questionnaire was designed to collect via survey the data important to the study. The data was obtained from 202 exporting SMEs in Thailand. Structural Equation Modelling (SEM) via AMOS, as well as Tests of Differences in Means including Independent Sample T-test and Two-way Analysis of Variance (ANOVA), were techniques employed for data analyses. The findings obtained from the SEM analysis showed that the EO concept did not exist in the context of Thailand and only one attribute of EO, i.e. proactiveness, was found to be crucial to export performance of Thai SMEs. The study also discovered that export environment hostility significantly moderated the relationship between proactiveness and export performance. The T-test results showed that only Thai SMEs with high proactiveness were likely to achieve high export performance. In addition, with the twoway ANOVA, the interaction effect between proactiveness and export environment hostility upon export performance was demonstrated, i.e. enterprises that were proactive when operating in less hostile export environments were high-performing. The findings also indicated that the enterprises that possessed a top manager with external locus of control (LOC) tended to achieve a higher level of performance than those with an internal LOC top manager. With the discovery of findings different from those provided by previous research, this study strengthens understanding of the EO concept and its relation to performance of SMEs in a context different from those frequently investigated in the past. Furthermore, the study is amongst the earliest that examines firm-level entrepreneurship from an international perspective in which there still is scarcity and fragmentation of knowledge. Theoretical, empirical, and praxis contributions and implications emerging from this study may help to consolidate normative theories and research in entrepreneurship for future scholars, as well as possibly helping to a particular extent to offer guidance useful to entrepreneurial practitioners.

The security of the scheme is due to a minimum index transmission error rate (ITER) introduced by an eavesdropper that increases significantly for higher-dimensional photon states. This allows for more noise in the transmission line, thereby increasing the possible distance between Alice and Bob without the need for intermediate nodes.

description: PGE$\sb2$ attenuates AVP-dependent solute transport in the medullary thick ascending limb of Henle (mTAL) and like the PGI$\sb2$ I-prostanoid (IP) receptor inhibits AVP-dependent water flow in the collecting duct. PGI$\sb2$ may play a role similar to PGE$\sb2$ in the mTAL. We therefore further characterize E-prostanoid (EP) receptor subtypes and the IP receptor in a freshly isolated suspension of rat mTAL. Using 10 nM PGE$\sb2,$ we confirmed previous work showing a Gi coupled EP$\sb3$ receptor subtype in rat mTAL that attenuates AVP-dependent cAMP by 70.7%. Pertussis toxin reversed this inhibitory response by 73.2%. In the absence of AVP, micromolar concentrations of PGE$\sb2$ and the EP$\sb2$ receptor subtype specific agonist butaprost produced significant elevations in cAMP levels, indicating the existence of the G$\rm\sb{s}$-coupled EP$\sb2$ receptor subtype. This response was insensitive to the EP$\sb4$ receptor subtype antagonist AH-23848B. Using the PGI$\sb2$ analogs iloprost (ILP) and cicaprost (CCP), we have demonstrated the presence of a Gi-coupled PGI$\sb2$ receptor. AVP-dependent cAMP was reduced 80% and 68.9% by 0.1uM ILP and 1 uM CCP respectively. Pertussis toxin reversed these inhibitory actions by 73%. Neither the EP$\sb3$ receptor subtype nor IP receptor inhibitory responses on AVP-dependent cAMP were sensitive to the EP$\sb1$ receptor subtype specific antagonist AH-6809 and the protein kinase C (PKC) inhibitors bisindolylmaleimide 1 and calphostin C. By associating in situ hybridization for receptor mRNA with TAL-specific Tamm-Horsfall glycoprotein immunostaining on serial sections from rat kidney, we have clearly shown EP$\sb3$ receptor subtype and IP receptor expression in the rat mTAL. These results suggest that a Gi-coupled IP receptor and the EP$\sb3$ receptor subtype play a role in attenuating the AVP-dependent cAMP in the rat mTAL.

description: As a solution to the problems of municipal solid waste management, anaerobic digestion possesses the optimal combination of volume reduction, probability of success and potential for both energy and resource recovery. An innovative application of anaerobic processes is the co-digestion of sewage sludge and the organic fraction of municipal solid waste (OFMSW). The purpose of this study is to evaluate the technical feasibility of this process in the context of typical Canadian solid waste. Lab-scale experiments were initially conducted using one litre batch bioreactors operated mesophilically (37$\sp\circ$C) and fed a mixture of primary sludge (RAW), thickened waste activated sludge (TWAS) and simulated OFMSW. To facilitate organics solubilization, three pretreatments were evaluated: thermal, alkaline and thermochemical. Using a central composite experimental design, two factors were studied, the total solids content of the feed and its particle size. For all three pretreatments, second order empirical models were developed with respect to common indicators of metabolic activity, namely, biogas production, biogas methane concentration, soluble chemical oxygen demand (COD) removal and total and volatile solids reduction.

Examining the new polytheism: A critical assessment of the concepts of self and gender archetypal psychology.
Creators: name: Fonda, Marc V.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1995
Subjects: subject: Religion, Philosophy of.

description: The hypothesis of this dissertation is that an alternative notion of selfhood is emerging in disparate areas of contemporary thought. This postmodern idea of selfhood may be seen as a reaction to traditional paradigms of human agency found in western mythology and theology, rationalist philosophy and psychology, and scientific positivism. It is not properly a new notion of selfhood insofar as many of the characteristics of self that are brought forward can be found in the history of ideas such as Romanticism and Neo-platonism. This alternate notion of selfhood emerges in two distinct areas of postmodern thought: archetypal psychology and contemporary feminist scholarship in religion. A critical assessment of archetypal psychology as informed by contemporary feminist theory is a necessary outcome of this investigation into an emerging concept of self in contemporary thought. One conclusion reached is that archetypal psychology is weak in its means of accounting for the body in how it theorizes about selfhood. Nonetheless, archetypal psychology and contemporary feminist thought can be seen as characterizing contemporary ideas of selfhood as follows: it is not singular or montheistic but diverse and polytheistic; it is more than merely rational--it is also based in the imagination; it demands the re-sacralization of both the body and the material world; it denies the belief that self is separated and autonomous, advocating the perspective that self communes with and is connected to the things and beings of the world; and, finally, it is not static, but is in the process of becoming what it will.
A test of Georgopoulos' model of organizational effectiveness adapted for co-operative education.

description: After a review of the literature, it was felt that the Model of Organizational Effectiveness in a Hospital Subsystem (Georgopoulos, 1986) was a possible framework from which to assess organizational effectiveness in co-operative education. In this study, a complete description of Georgopoulos' model is provided with a parallel presentation of the adaptability of the model to co-operative education. For Georgopoulos (1986), the emergency department is viewed as a complex, work performing, and problem solving open system which is dependent on the internal and external environment for survival. According to Georgopoulos, organizational effectiveness is the joint outcome of three kinds of efficiency, economic, clinical, and social. As well, he feels there are many factors which facilitate or hinder organizational effectiveness in the department, as an open system. In his model, various elements of structure, including certain inputs, relate to the problem solving adequacy of those who work together to deliver health care. Furthermore, each of the components also relates to the outcomes or organizational effectiveness. For this study, it was felt that if co-operative education was viewed not as a program but as a subsystem within the school then Georgopoulos' model should seemingly provide a comprehensive framework to study co-operative education. As a result, a model was adapted by the researcher from the work of Georgopoulos (1986). Therefore, the purpose of the study was to test the Model of Organizational Effectiveness Adapted for Co-operative Education in order to determine whether the model was appropriate to assess relationships among variables which comprise the main components of the co-operative education subsystem, namely inputs, elements of structure, internal problem solving activities, and outcomes. Due to various limitations including issues of anonymity, sample size, and certain variables which were constant among school boards involved in this study, not all the components of the model were tested. Therefore, a reduced set of variables was included for study. Variables used to test the model included student inputs (achievement at the time of entry into co-operative education, level of study, motivation, reason for participating, part-time and volunteer work experiences), structure (size and location of school, maturity of co-operative education program, number of students and teachers involved in co-operative education), problem solving activities (coordination, integration, strain, adaptation, resource allocation), and three outcomes of organizational effectiveness (educational efficiency, achievement, student satisfaction).

description: To provide effective support, process-aware information systems (PAIS) must not freeze existing business processes. Instead they should enable authorized users to deviate on-the-fly from the implemented processes and to dynamically evolve them over time. While there has been a lot of work on the theoretical foundations of dynamic process changes, there is still a lack of PAIS implementing this dynamics. Designing the architecture of respective technology constitutes a big challenge due to the high complexity coming with dynamic processes. Besides this, performance, robustness, security and usability of the system must not be affected by the added flexibility. In the AristaFlow project we have taken a holistic approach to master this complexity. Based on a conceptual framework for flexible process enactment and dynamic processes, we have designed a sophisticated architecture for next generation process management technology. This paper discusses major design goals and basic architectural principles, gives insights into selected system components, and shows how change support features can be realized in an integrated and effective manner.

description: This thesis examines the educational adaptation of children of black immigrants from Africa and the Caribbean. The influence of common shared values on the educational attainment of a segment of the new second generation---Black children of immigrants---is explored. The data are drawn from the 2002 Ethnic Diversity Survey. The findings illustrate that the educational experience of black children of immigrants is heterogeneous. Depending on both socioeconomic and ethnic attachment factors, different educational outcomes for black children of immigrants were observed.
