Exploring the latitude of attitude: Intentions to breastfeed among adolescents in Lebanese schools.

School-based breastfeeding education (SBBE) may help improve breastfeeding rates in the long-term by targeting children and adolescents' knowledge, attitudes, skills, and intentions. Breastfeeding rates in Lebanon are suboptimal. Psychosocial drivers of breastfeeding intention among the youth are unknown. We administered a survey to 658 high school students (448 females; 210 males) at two large Lebanese schools to understand intentions, intention drivers, and views on SBBE as means to guide SBBE programme design on the basis of the theory of planned behaviour. We collected information on demographics, intention to breastfeed/support wife to breastfeed future. Intention was predicted by attitude related to breastfeeding health outcomes and family normative beliefs-χ2 (25) = 115, P < .001 for males, and χ2 (39.3) = 186, P < .001 for females. Among females, intention was also positively associated with being breastfed, higher socio-economic status, and being more accepting of public breastfeeding. Seventy-eight per cent of students felt they were not learning enough about breastfeeding in school but were interested in SBBE through didactic teaching methods and interactive experiences. Findings indicate that breastfeeding intention among adolescent students is not merely influenced by the extent of knowledge but by more complicated psychosocial drivers that may differ by gender. Our findings also suggest a misalignment exists between what schools are providing with what students feel they need, thereby opening up a potential space for intervention

Transition in a numerical model of contact line dynamics and forced dewetting

We investigate the transition to a Landau-Levich-Derjaguin film in forced dewetting using a quadtree adaptive solution to the Navier-Stokes equations with surface tension. We use a discretization of the capillary forces near the receding contact line that yields an equilibrium for a specified contact angle $\theta_\Delta$ called the numerical contact angle. Despite the well-known contact line singularity, dynamic simulations can proceed without any explicit additional numerical procedure. We investigate angles from $15^\circ$ to $110^\circ$ and capillary numbers from $0.00085$ to $0.2$ where the mesh size $\Delta$ is varied in the range of $0.0035$ to $0.06$ of the capillary length $l_c$. To interpret the results, we use Cox's theory which involves a microscopic distance $r_m$ and a microscopic angle $\theta_e$. In the numerical case, the equivalent of $\theta_e$ is the angle $\theta_\Delta$ and we find that Cox's theory also applies. We introduce the scaling factor or gauge function $\phi$ so that $r_m = \Delta/\phi$ and estimate this gauge function by comparing our numerics to Cox's theory. The comparison provides a direct assessment of the agreement of the numerics with Cox's theory and reveals a critical feature of the numerical treatment of contact line dynamics: agreement is poor at small angles while it is better at large angles. This scaling factor is shown to depend only on $\theta_\Delta$ and the viscosity ratio $q$. In the case of small $\theta_e$, we use the prediction by Eggers [Phys. Rev. Lett., vol. 93, pp 094502, 2004] of the critical capillary number for the Landau-Levich-Derjaguin forced dewetting transition. We generalize this prediction to large $\theta_e$ and arbitrary $q$ and express the critical capillary number as a function of $\theta_e$ and $r_m$. An analogy can be drawn between $r_m$ and the numerical slip length.Comment: This version of the paper includes the corrections indicated in Ref. [1

Essays on contemporary issues in the South Korean economy.

Belghitar, Yacine - Associate SupervisorThis doctoral thesis sheds light on some issues that are characteristic of the South Korean socioeconomic landscape today. In a series of three papers, I empirically address important questions faced by policy makers of this country, whilst also contributing to major debates currently taking place within the Economics discipline. In the first chapter, I investigate the effects of robotization on Korean workers’ labor supply from the lens of dynamic monopsony. I show that an increase in the density of industrial robots is associated with manufacturing workers becoming more responsive to a change in wages in their decision to quit to non-employment, and that the opposite is true for non-manufacturing workers. The second chapter contributes to the discussion on youth unemployment in South Korea, in tandem with the question of the high turnover rate within the nation’s Nursing profession. I find that the unemployment rate at time of graduation has scarring effects on Nurses’ wages, workhours, and subjective wellbeing. The final chapter of this dissertation tackles the problem of social isolation among Korean elders and contributes to the very small literature on the economic determinants of this phenomenon. I offer the first set of causal evidence linking the social isolation of elders with their adult children’s inheritance expectations.PhD in Economics and Financ

Preparation and Loading with Rifampicin of Sub-50 nm Poly(ethyl cyanoacrylate) Nanoparticles by Semicontinuous Heterophase Polymerization

We report the preparation of poly(ethyl cyanoacrylate) (PECA) nanoparticles by semicontinuous heterophase polymerization carried out at monomer starved conditions at three monomer addition rates. Particles in the nanometer range were obtained, the size of which diminishes with decreasing monomer addition rate as shown by the fact that particles with mean diameters of ca. 42 and 30 nm were obtained at the faster and intermediate dosing rates, respectively, whereas two populations of particles, one of 15.5 and the other of 36 nm in mean diameters, were produced at the slower dosing rate. The obtained molecular weights were from 2,200 to 3,500 g/mol, depending on the addition rate, which are typical of the anionic polymerizations of cyanoacrylates in aqueous dispersions at low pHs. The rifampicin (RIF) loading into the nanoparticles was successful since the entire drug added was incorporated. The drug release study carried out at pH of 7.2 indicated a faster release from the free RIF at intermediate and larger release times as expected since, in the nanoparticles, first the drug has to diffuse through the nanoparticle structure. The comparison of several drug release models indicates that the RIF release from PECA nanoparticles follows that of Higuchi

Evaluating Students’ Perceived Stress, Sleep Quality, and Physical Activity in Exercise Is Medicine® On Campus Student-led Health Consultation Program

The American College of Sport Medicine created the Exercise is Medicine® (EIM) initiative to improve health through the promotion and prescription of physical activity. The EIM-On Campus (EIM-OC) initiative uses physical activity as a vital sign for promoting healthy behaviors among students and employees on a college campus. The EIM-OC initiative was launched at California State University, Monterey Bay (CSUMB) in Fall 2019. The purpose of this research project was to promote and evaluate college students’ health behaviors associated with the implementation of the EIM-OC initiative at CSUMB. We hypothesized significant improvements in perceived stress, sleep quality, and total physical activity time among participants. The research design was pre-post and tracked participants in the EIM-OC semester long consultation program. Fifteen CSUMB students participated in the consultation program. The Perceived Stress Scale (PSS), Pittsburgh Sleep Quality Index (PSQI), and the Godin-Leisure Time Exercise Questionnaire (GLTEQ) were administered online through an intake form before and after the consultation program. Dependent t-tests were performed to assess for pre- and post-differences in perceived stress (PS), sleep quality (SQ), and total physical activity (PA) time. Significance was set at = 0.05. Participant’s age was M=20.87, SD=3.34 years, with 60% being college junior status. There was a statistically significant improvement in students’ perceived stress levels (t=2.659, df=14, p=.019) pre (M=16.47, SD=5.630) and post (M=11.53, SD=6.424) intervention. There was also a statistically significant improvement in sleep quality (t=.3166, df=14, p=.007) pre (M=6.80, SD=2.981) and post (M=5.07, SD=2.963) intervention. There were improvements in total physical activity time, although it was not significant. The results of this research project indicate that peer advisor consultation programs can be effective in improving college-aged students’ perceived stress and sleep quality. These health behavior improvements are important contributors to college students’ lifelong health behavior habits, quality of life, and academic performance

Temporal variation in pollination services to Cucurbita moschata is determined by bee gender and diversity

It has been proposed that species-rich insect communities and species turnover across landscapes enhance the pollination efficiency of crops through complementarity, where both the dominant and less abundant species contribute to reaching a yield threshold from pollination. Alternatively, fluctuations in the most abundant pollinator species, rather than changes in species richness, may drive temporal variation in pollination services. In this study, we used Cucurbita moschata as a model to investigate temporal variation in pollinator communities in a Mexican tropical dry forest region. We sampled floral visitors in the coastal region of Jalisco during the wet and dry seasons and determined the pollination efficiency of all floral visitors. Our results showed that there was temporal variation in the pollinator community and in the pollination efficiency of the main pollinators of Cucurbita moschata crops. In the wet season, native bees of the genus Peponapis were the most frequent and effective pollinators of C. moschata, whereas in the dry season, Peponapis bees were scarce and Apis mellifera became the most frequent floral visitor. Apis mellifera transfers smaller pollen loads than Peponapis, but it provides an effective pollination service in conjunction with other native bees during the dry season. There was also an interaction between flower gender and pollinator species, where A. mellifera had higher visitation rate to female C. moschata flowers, and Peponapis bees to staminate flowers. Mean visitation rate by Peponapis female bees was 17 times higher than visitation rate by male bees. This is the first report of a vis-à-vis relationship of pollinator gender with respect to plant gender in which plants of the genus Cucurbita that produce unisexual staminate and pistillate flowers are differentially visited by Peponapis male and female bees, where females are the main pollinators. Understanding the temporal variation in pollinator communities and the contribution of the different species of pollinators to the reproductive success of different crop species and varieties can be crucial to maintaining pollination services under the current global pollination crisis.Fil: Delgado-Carrillo, Oliverio.

Prescription and Other Medication Use in Pregnancy

OBJECTIVE: To characterize prescription and other medication use in a geographically and ethnically diverse cohort of women in their first pregnancy. METHODS: In a prospective, longitudinal cohort study of nulliparous women followed through pregnancy from the first trimester, medication use was chronicled longitudinally throughout pregnancy. Structured questions and aids were used to capture all medications taken as well as reasons they were taken. Total counts of all medications taken including number in each category and class were captured. Additionally, reasons the medications were taken were recorded. Trends in medications taken across pregnancy and in the first trimester were determined. RESULTS: Of the 9,546 study participants, 9,272 (97.1%) women took at least one medication during pregnancy with 9,139 (95.7%) taking a medication in the first trimester. Polypharmacy, defined as taking at least five medications, occurred in 2,915 (30.5%) women. Excluding vitamins, supplements, and vaccines, 73.4% of women took a medication during pregnancy with 55.1% taking one in the first trimester. The categories of drugs taken in pregnancy and in the first trimester include the following: gastrointestinal or antiemetic agents (34.3%, 19.5%), antibiotics (25.5%, 12.6%), and analgesics (23.7%, 15.6%, which includes 3.6%; 1.4% taking an opioid pain medication). CONCLUSION: In this geographically and ethnically diverse cohort of nulliparous pregnant women, medication use was nearly universal and polypharmacy was common

Simultaneous detection of the three ilarviruses affecting stone fruit trees by nonisotopic molecular hybridization and multiplex reverse-transcription polymerase chain reaction

[EN] The three most economically damaging ilarviruses affecting stone fruit trees on a worldwide scale are the related Prunus necrotic ringspot virus (PNRSV), Prune dwarf virus (PDV), and Apple mosaic virus (ApMV). Nonisotopic molecular hybridization and multiplex reverse-transcription polymerase chain reaction (RT-PCR) methodologies were developed that could detect all these viruses simultaneously. The latter technique was advantageous because it was discriminatory. For RT-PCR, a degenerate antisense primer was designed which was used in conjunction with three virus-specific sense primers. The amplification efficiencies for the detection of the three viruses in the multiplex RT-PCR reaction were identical to those obtained in the single RT-PCR reactions for individual viruses. This cocktail of primers was able to amplify sequences from all of the PNRSV, ApMV, and PDV isolates tested in five Prunus spp. hosts (almond, apricot, cherry, peach, and plum) occurring naturally in single or multiple infections. For ApMV isolates, differences in the electrophoretic mobilities of the PCR products were observed. The nucleotide sequence of the amplified products of two representative ApMV isolates was determined, and comparative analysis revealed the existence of a 28-nucleotide deletion in the sequence of isolates showing the faster electrophoretic mobility. To our knowledge, this is the first report on the simultaneous detection of three plant viruses by multiplex RT-PCR in woody hosts. This multiplex RT-PCR could be a useful time and cost saving method for indexing these three ilarviruses, which damage stone fruit tree yields, and for the analysis of mother plants in certification programs.We thank Drs. P.H. Berger and P.J. Shield for providing the ApMV clone and Dr. S. Scott for the PDV clone. We also thank P. Thomas and M.W. van der Heidjen for help with the English version of the manuscript.
