Heart rate variability biofeedback for college students recovering from substance use disorder: a longitudinal analysis of craving changes
No full textPurpose: The purpose of this dissertation was to provide longitudinal evidence on heart rate variability biofeedback (HRVB) as an anti-craving intervention for college students recovering from substance use disorder (SUD). Methods: Previous studies showed promise of the therapeutic potential of HRVB to reduce substance craving. Gaps in the literature indicated the need for a longitudinal examination of craving changes that takes individual differences into consideration. Data from 46 college students recovering from SUD were used to examine craving changes before and during an eight-session HRVB intervention. Participants were assessed at four occasions in the control condition over the first 12 weeks followed by 8 occasions in the experimental condition, separated by an 11-week rest period. A longitudinal multilevel modeling approach was used with time at level-1 nested within persons at level-2. Unconditional and conditional multilevel models of change were estimated to model craving trajectories and predictor relationships over time. Results: Significant reductions in substance craving were observed during HRVB compared to waitlist. HRVB seemed to enhance the efficacy of conventional therapies by producing craving reductions that were not evident prior to the HRVB intervention despite usual treatment. A continued daily HRVB practice of more than 12 minutes was found to enhance treatment as usual outcomes and contribute to greater craving reductions over time. In our sample, younger participants seemed to be more committed to daily HRVB practice, although many did not achieve the recommended daily practice of 15 minutes twice daily. Increases in depressive symptoms were found to attenuate the effects of HRVB on craving. Anxiety and perceived stress were not significantly associated with craving in this study. The true R2 for the final model indicated that 20.5% of the variance in craving was explained by age, daily HRVB >12 minutes, and the within-person aspect of depression. Conclusions: HRVB is an easily accessible and affordable intervention that shows promise as a complementary anti-craving intervention. The outcomes of this study have implications for hypothesized HRVB practice-dose relationships. Nurses may help persons recovering from SUD to better manage the symptom of craving by the routine and strategic use of personal HRVB practice.Ph.D.Includes bibliographical referencesby Nour Alaya
A revised completeness result for the simply typed -calculus using realizability semantics
No full textIn this paper, we define a new realizability semantics for the simply typed
lambda-mu-calculus. We show that if a term is typable, then it inhabits the
interpretation of its type. We also prove a completeness result of our
realizability semantics using a particular term model. This paper corrects some

Radical hospitality:American policy, media, and immigration /
No full textRadical Hospitality: American Policy, Media, and Immigration re-imagines the ethical relationship of host societies towards newcomers by applying the concept of hospitality to two specific realms that impact the lives of immigrants in the United States: policy and media. The book calls attention to the moral responsibility of the host in welcoming a stranger. It sets the stage for the analysis with a historical background of the first host-guest diads of American hospitality, arguing that the early history of American hospitality was marked by the degeneration of the host-guest relationship into one of host-hostage, normalizing a racial discrimination that continues to plague immigration hospitality to this day. Author Nour Halabi presents a historical policy and media discourse analysis of immigration regulation and media coverage during three periods of US history: the 1880s and the Chinese Exclusion Act, the 1920s and the National Origins Act and the 2000s and the Muslim travel ban. In so doing, it demonstrates how U.S. immigration hospitality, from its peaks in the post-Independence period to its nadir in the Muslim travel ban, has fallen short of true hospitality in spite of the nation's oft-touted identity as a "nation of immigrants." At the same time, the book calls attention to how a discourse of hospitality, although fraught, may allow a radical reimagining of belonging and authority that unsettles settler-colonial assumptions of belonging and welcome a restorative outlook to immigration policy and its media coverage in society
Lysine degradation by ruminal Fusobacteriumnecrophorum
Get PDFThree experiments were conducted to characterize lysine fermentation by Fusobacterium necrophorum, a ruminal bacterium that is known to degrade amino acids. In Experiment 1, 7 strains of Fusobacterium necrophorum were inoculated into media containing lysine (50 mM), lactate (50 mM), or lysine plus lactate (50 mM each) as the major energy substrate to evaluate growth and ammonia production. All strains grew with lysine, lactate, or lactate plus lysine as the primary substrate. When grown with lysine, all strains produced ammonia as an end product, even if lactate was also present. Smaller concentrations of ammonia for medium containing lactate plus lysine when compared with lysine alone indicate that the Fusobacterium strains used lactate as a growth substrate that stimulated utilization of ammonia. In Experiment 2, the 2 strains tested were able to degrade extensively both lysine and glutamic acid. Some evidence was detected for partial utilization for growth of histidine, methionine, and tryptophan by strain A21. In Experiment 3, the minimum inhibitory concentration (MIC) of the antibiotic tylosin was 25 μg/mL when Fusobacterium necrophorum strains A21 and B35 were grown in either lysine or lactate-enriched medium. The MIC of monensin was 6.25 and 3.9 μg/mL for strains A21 and B35, respectively, when grown in lysine-enriched medium, but\u3e50 and 10.9 μg/mL when the strains were grown in lactate-enriched medium. These findings may lead to ways that ruminal lysine degradation may be controlled.; Dairy Day, 2010, Kansas State University, Manhattan, KS, 2010; Dairy Research, 2010 is known as Dairy Day, 201
Strategy for approaching the regulation of public transportation in Kuwait
No full textThis electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Thesis: M.C.P., Massachusetts Institute of Technology, Department of Urban Studies and Planning, 2019Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 66-69).There is an increasing concern about the growth of car dependence in the Middle East and its associated negative impacts on cities, including economic and environmental factors, urban form, and lifestyle. Kuwait, having undergone massive infrastructure developments after the discovery of oil, is considered a prime example of an automobile-dependent city-state in the region. Public transportation is irregular and limited and has been traditionally aimed at the lower-class migrant population rather than the residents of the country as a whole. Planning and regulating for the existing public transportation is minimal and siloed. Against this background, this thesis evaluates the current state of public transportation in Kuwait and develops a framework to assess industry structure models for the regulation of public transportation. Dubai, Abu Dhabi, and Riyadh are used as cases representing a unified public model, closely supervised private model, and loosely supervised private model, respectively. Using the framework and the cases, it recommends the adoption of the closely supervised private model for the Kuwaiti context. This thesis also provides five recommendations on how to push for regulatory change for KuwaitCommute, a local social initiative intent on bringing awareness to Kuwait's public transportation system and the country's traffic epidemic. However, further research is still required when looking at how various industry models enforce their respective regulatory regimes.by Nour Maher Ghadanfar.M.C.P.M.C.P.

Applied Physics Letters, 113(12), 122106. https://doi.org/10.1063/1.5051457Scandium nitride single crystals (14–90 μm thick) were grown on a tungsten (100) single crystal substrate by physical vapor transport in the temperature range of 1850 °C–2000 °C and pressure of 15–35 Torr. Epitaxial growth was confirmed using in-plane ϕ scan and out-of-plane x-ray diffraction techniques which revealed that ScN exhibits cube-on-cube growth with a plane relationship ScN (001) ǁ W (001) and normal direction ScN [100] ǁ W [110]. Atomic force microscopy revealed that the surface roughness decreased from 83 nm to 18 nm as the growth temperature was increased. The x-ray diffraction rocking curve (XRC) widths decreased with temperature, indicating that the crystal quality improved as the growth temperature increased. The lowest XRC FWHM was 821 arcsec which is so far the lowest value reported for ScN. Scanning electron microscopy exhibited the formation of macrosteps and cracks on the crystal surface with the latter due to the mismatch of ScN and tungsten coefficients of thermal expansion
Bioavailability of lysine from hydroxymethyl lysine
Get PDFTwelve mature sheep were used as a ruminant model to estimate the bioavailability of lysine in hydroxymethyl lysine (HML) compared with a commercial product of rumen-protected lysine (RPL; LysiPEARL, Kemin Industries, Inc.) with known availability. The sheep were fed a diet with a forage to concentrate ratio similar to that of dairy diets. Following a control period in which plasma lysine was measured when sheep received no supplemental lysine, the sheep were provided 2 of 4 treatments during periods 2 and 3; treatments included RPL to provide 3 or 6 g/day of available lysine (actual amounts of product provided were based on the manufacturer\u27s data related to ruminal escape and intestinal availability) and 3 or 6 g/day of lysine provided as HML. Blood samples were collected at the end of each feeding period at 3 hours after feeding. Both HML and RPL significantly increased plasma lysine concentrations. By comparison with plasma lysine concentrations when known amounts of bioavailable lysine were provided as RPL, the bioavailability of lysine in HML was estimated to be 94%. Results indicate that HML may be an effective means of supplementing lysine to dairy cattle.; Dairy Day, 2010, Kansas State University, Manhattan, KS, 2010; Dairy Research, 2010 is known as Dairy Day, 201
Master′s and doctoral theses in family medicine and their publication output, Suez Canal University, Egypt
No full textBackground: The completion of a thesis is a significant requirement for both a Master′s and a doctorate degree in general practice/family medicine (GP/FM). A postgraduate thesis is a well-planned, time-intensive activity carried out over several years. The quality of the theses can be judged by the proportion of published papers. Objective: This study aimed to describe Master′s and doctoral theses in family medicine and their publications between 1982 and 2014. Materials and Methods: GP/FM degree theses were reviewed at the Faculty of Medicine and central Suez Canal libraries. Several characteristics were extracted from each thesis relating to the main researcher, supervisors, themes, and study methods according to predefined criteria. Publications from the theses were described. Results: Over 33 years, 208 theses were completed by 173 GP/FM researchers. The majority of the theses were for Master′s degrees (84.1%). Regarding the study design, most of the degree theses were cross-sectional studies (76.9%). The adult population was targeted in 33.7% of research theses. Nonprobability sampling was used in 51%. Rural communities were the setting of research in 43.8%, and primary health center (PHC)-based studies in 59.1%. The "Patient" category exceeded the other categories (28.4%). Publication from theses started in the second decade of research production. Of the degree theses, 21.6% original articles were published. Only 13.3% of articles from theses were published in PubMed-indexed journals. The researcher was first author in 62.2% of published articles. Conclusion: The production of GP/FM theses and their publications are going to increase. Continuous assessment and planning for GP/FM studies are recommended
