    Top- and bottom-mass effects in hadronic Higgs production at small transverse momenta through LO+NLL

    Full text link
    The resummed transverse momentum distribution of the Higgs boson in gluon fusion through LO+NLL for small transverse momenta is considered, where the Higgs is produced through a top- and bottom-quark loop. We study the mass effects with respect to the infinite top-mass approach. The top-mass effects are small and the heavy-top limit is valid to better than 4% as long as the Higgs' transverse momentum stays below 150 GeV. When the bottom loop is considered as well, the discrepancy reaches up to about 10%. We conclude that bottom-mass effects cannot be included in a reasonable manner by a naive reweighting procedure in the heavy-top limit. We compare our results to an earlier, alternative approach based on POWHEG.Comment: 20 pages, 8 figure

    Transverse momentum resummation for Higgs production via gluon fusion in the MSSM

    The resummed transverse momentum distribution of supersymmetric Higgs bosons produced through gluon fusion at NLO+NLL is presented, including the exact quark and squark mass dependences. Considering various MSSM scenarios, we compare our results to previous ones within the POWHEG approach. We analyze the impact of the bottom loop which becomes the dominant contribution to the gluon fusion cross section for a wide range of the parameter space for the pseudo-scalar and heavy Higgs.Comment: 33 pages, 13 figure

    Motivational Interviewing Via Co-Active Life Coaching as an Intervention for Tobacco Control

    The purpose of this Motivational Interviewing (MI) via Co-Active Life Coaching (CALC) research program in tobacco control was to assess the effectiveness of this individualized, interactive intervention. This was achieved through a critical appraisal and literature review of the individual dimensions of MI currently used in cognitive-behavioural smoking cessation interventions, as well as MI applied via CALC intervention studies at both the individual- and population-levels. Article 1 provides the critically appraised and systematic review of literature exploring three dimensions of MI (social support, motivation, and tailored interventions) which were implemented independently in cognitive-behavioural cessation interventions. The effectiveness of these dimensions at promoting cessation was assessed and yielded mixed results. The purpose of Article 2 was to assess the impact of MI-via-CALC on selected cessation outcomes among young adults (19-25 years) and found the immediate intervention group, compared to the waitlist group, had a significant reduction in smoking behaviours (number of cigarettes smoked per day and cigarette dependency) and significant increases in personal competency (self-esteem and self-efficacy). Additionally, at 12-months post-intervention a cessation rate of 31.4% was reported and biochemically verified. Lastly, Article 3 assessed the impact of a full-day application-based MI-via-CALC training on the perceived competency of employees of a national smokers’ telephone hotline to facilitate behaviour change among callers. Post- training participants described skill development, increased competency at facilitating behaviour change, and desire for additional training. This research program was comprised of three unique studies. This was the first critical appraisal and literature review to assess cognitive-behavioural cessation interventions through an MI lens. The core components of MI-via-CALC are similar to components already utilized individually in cessation interventions; however, unique to MI-via-CALC is the incorporation of these components into one intervention. Moreover, this was the largest individual MI-via-CALC intervention tobacco study to date and the only one with a control group. Furthermore, the cessation rates observed in this intervention study are beyond those currently observed in other cognitive-behavioural interventions as well as nicotine replacement therapy studies. Lastly, the MI-via-CALC training offered to employees of a national smoker’s hotline was also a first, as the hotline typically does not allow outside researchers within their organization. Overwhelmingly, the training was well received, and the impact was self-reported behaviour change resulting in ameliorated client interactions to promote cessation. Together, the important findings of these ground-breaking studies underscore the need for continued investigation of MI-via-CALC as an intervention for tobacco control

    ASSESSING THE IMPACT OF CO-ACTIVE LIFE COACHING AS AN INTERVENTION FOR SMOKING CESSATION: A DEMONSTRATION STUDY

    The purpose of this demonstration study involving adults aged 19-29 was to assess Co- Active Life Coaching (CALC) compared to a control condition on facilitating smoking cessation utilizing various constructs linked with cessation. The study also qualitatively explore smoking triggers and obstacles to cessation, and participants’ coaching experiences. In this repeated measures, between groups design 20 participants were randomly assigned to either the CALC or control group. Between groups there was a statistically significant difference in group retention (90% CALC versus 30% control group,/) \u3c .05). Across time, statistically significant differences were observed in smoking cessation; decrease in number of cigarettes smoked per day and cigarette dependency; and increases in both internal and external self-efficacy. Qualitatively, stress and social situations were identified as triggers; the main cessation obstacle was the control and cigarette relationship; and only the CALC group found coaching to aid in cessatio

    A rural shelter in Ontario adapting to address the changing needs of women who have experienced intimate partner violence: A qualitative case study

    Introduction: Intimate partner violence is a significant public health problem, with shelters offering the predominant communitybased solution. Shelters in Canada are mandated to provide a safe place, protection planning, advocacy and counseling among other services. Recently it has been noted the role of the shelter was shifting from an inpatient to outpatient model with a focus on increased integration of health and social services. This changing role of the shelter is amplified within the rural context where resources and cultural norms may be limited or incompatible with help-seeking behaviors. Women\u27s shelters located in rural settings provide services within a specific cultural context that can be at odds with the needs of women who have experienced abuse, because cultural values such as rural pride, lack of anonymity, and lack of services may inhibit access to health and social services. Methods: The purpose of this in-depth qualitative case study was to examine and explore how one rural Canadian women\u27s shelter role was changing and how the shelter was adapting to achieve the changing role. The theoretical framework utilized was a feminist intersectional lens. Qualitative interviews (averaging 60 minutes) were conducted with shelter service providers (n = 6) and women staying in the shelter or utilizing shelter services (n = 4). Throughout semi-structured interviews, data-trustworthy steps were taken including member-checking and paraphrasing to ensure data were an accurate representation of participants\u27 experiences. Inductive content analysis of all interviews and field notes was conducted independently by two researchers. Results: Analysis revealed the shelter\u27s role was changing to include filling gaps, case management, and system navigation. To achieve the changing role, relationship building, community mobilization (both education and empowerment), and redesigning delivery were implemented as adaptation strategies. Together both the changing role of the shelter and the adaptation strategies being implemented were found to be working toward a larger goal of transformation of cultural and structural norms related to violence against women. Conclusions: This study uniquely identified the specific changes to the role of one rural Canadian shelter and the adaptations strategies utilized to adapt to the changing needs of women. The changing role of the shelter and the adaptation strategies being utilized have significant implications for the health of women given the increased use of healthcare services for women who have experienced violence. Specifically, the changing role of the shelter has the potential to decrease healthcare service use while increasing the potential fit of services. Further research is required to assess the impact of the changing role of the shelter on the healthcare needs and outcomes for women who have experienced intimate partner violence
