    Basis Set Convergence and Empirical Approaches for Obtaining Accurate Diagonal Born−Oppenheimer Corrections from an Extensive Database of 200 Structurally Diverse Hydrocarbons
    (American Chemical Society)

    The Born−Oppenheimer (BO) approximation is fundamental to computational chemistry because it drastically simplifies the time-independent Schrödinger equation, making calculations for molecular systems computationally feasible. Accurate determination of the diagonal Born−Oppenheimer correction (DBOC) is essential for achieving benchmark accuracy in high-level thermochemical applications. Here, we establish the DBOC200HC database, consisting of 200 structurally diverse hydrocarbons with up to 18 carbon atoms (e.g., triamantane (C18H24)), including aliphatic, aromatic, antiaromatic, cyclic, noncyclic, and caged systems. Reference DBOCs are determined near the coupled-cluster singles and doubles complete basis set limit (CCSD/CBS) using additivity schemes based on HF/cc-pVQZ and CCSD/cc-pVnZ (n = D, T) calculations. Given the computational expense associated with CCSD/CBS calculations for large hydrocarbons, it is important to develop reliable yet computationally economical approximations. Several such approaches are assessed using the DBOC200HC database. While scaled Hartree−Fock methods offer limited improvement, methods incorporating first-order Møller−Plesset perturbation theory (MP1) perform significantly better. Specifically, calculating the DBOC at the MP1/cc-pVDZ level of theory and scaling the MP1 correlation component (ΔEDBOC MP1 = EDBOC MP1 − EDBOC HF ) by an empirical factor of 1.5447 yields the best balance between accuracy (RMSD = 0.026 kJ/mol) and computational cost (practically the same cost as HF/cc-pVDZ). This exceptionally low RMSD suggests that highly accurate DBOCs for use in high-level thermochemical protocols can be obtained via the scaled MP1 approach, without resorting to computationally more demanding levels of theory such as MP2 or CCSD. To validate our results, we further test the empirical methods optimized over the DBOC200HC database on an independent database of 12 larger hydrocarbons, including systems like dodecahedrane(CH)20.

    Objectives We aimed to explore sex-specific differences in resting blood pressure (BP) reduction and associated cardiovascular adaptations following isometric exercise training (IET).

    Methods 100 sedentary adults with normal to high-normal systolic BP volunteered for the study. Participants either performed home-based lower-body IET in the form of a wall squat three times a week for 4 weeks (each session comprised 4×2min bouts) or were allocated to the control group. Cardiovascular variables, including BP, cardiac output, total peripheral resistance, stroke volume and heart rate variability (HRV), were measured at rest preintervention and postintervention.

    Results Following 4 weeks of IET, there were no significant differences in resting systolic BP and diastolic BP between females (122.1±6.9 and 80.0±8.3mm Hg) and males (119.6±7.2 and 77.4±8.6mm Hg). However, female participants had a greater cardiac autonomic response following training, evidenced by a lower lowfrequency to high-frequency HRV ratio (F: 1.38±1.27 and M: 2.1±1.5, p=0.004) and decreased and elevated lowfrequency normalised units (F: 50.3%±16.2%and M: 60.9%±16.9%, p=0.015) and high-frequency normalised units (F: 49.7%±16.2%and M: 39.1%±16.9%, p=0.015), respectively.

    Conclusions While resting BP reductions were comparable between female and male participants, there was a greater autonomic response and a higher incidence of clinically important BP reductions in females, which could indicate a greater cardioprotective effect following IET. These findings highlight the importance of considering sex differences in the prescription and evaluation of exercise interventions for hypertension management.

    Exploring Experiences of the New Graduate Registered Nurse in Caring for the Deteriorating Patient in Rural Areas: A Qualitative Study
    (Wiley-Blackwell Publishing Ltd) ;
    Lea, Jackie
    ;

    Aim: To explore the experiences of new graduate registered nurses in caring for the deteriorating patient in rural areas.

    Background: New graduate registered nurses often feel unprepared to care for the deteriorating patient. Whilst literature has recognised new graduate registered nurses working within metropolitan areas feel ill-equipped to care for deteriorating patients, there is a paucity of literature focused on experiences within the rural context.

    Design: Qualitative, descriptive phenomenological approach.

    Methods: In-depth interviews were undertaken with 7 participants in rural Eastern Australia with collected data being subject to thematic analysis.

    Results: Three themes were identified that shares the lived experiences of the participants as they transitioned into the rural team: First encounters—Transition to the rural team; Practice support for managing deterioration; and The road to confidence.

    Conclusion: New graduate registered nurses are unprepared to care for the deteriorating patient in rural areas. Practice support and barriers to ongoing education are influential on their experience with findings from this study supporting focused rural healthcare preparation from tertiary education providers, plus structured practice support from senior rural nurses and health facility orientation programs. Preparation should include the use of digital technologies and escalation and management of the deteriorating patient alongside rural policies and procedures to enhance patient safety and support new graduate rural nurses.

    Implications for the Profession and/or Patient Care: The findings have implications for tertiary undergraduate nursing education and those supporting New Graduate Registered Nurses in their transition to practice in rural areas. Enhancement of new graduate nurses' skills and abilities in recognition and responding to patient deterioration through both technological and personnel support will enhance patient safety within rural health care.

    Reporting Method: Standards for Reporting Qualitative Research (SRQR).

    Patient or Public Contribution: 7 participants were involved in the study.

    Punitive attitudes in Australia: Investigating the rural-urban divide

    Research exploring punitive attitudes across different geographic locations is limited. Available research suggests that rural residents may be less tolerant of crime and more likely to hold punitive attitudes when compared to their urban counterparts. However, we have little understanding of this difference. Drawing on survey data from a representative sample of the Australian public (Urban 77.1 %, N = 401 and Rural 22.9 %, N = 119), this study explores differences in punitive attitudes among rural and urban Australians and examines the factors contributing to this difference. The findings indicate that Australians hold somewhat punitive attitudes, with rural respondents being significantly more punitive than urban respondents. Moreover, increased fear of crime and a lack of confidence in the criminal justice system moderate the difference in punitive attitudes across rural and urban areas. The findings provide support for the role of spatiality in shaping attitudes, including those towards crime and punishment. The practical and theoretical implications of these findings are discussed.

    Orgasmic Gushing: where does the fluid come from and how is it produced?
    (Women in Research (WiR), 2005)
    O'Brien, GM
    There are three sexual fluids from women: lubrication (e.g. transudation of fluid across the mucosa of the vagina, and mucus from the greater vestibular glands); female ejaculation (from paraurethral glands); and gushing. Orthodox western medicine and physiology does not yet have a standardized description or explanation for the third, gushing. The present paper proposes that the gushing fluid is a filtrate of plasma, produced by the mechanism known as transudation. This is an additional application for the transudation mechanism, after the well accepted roles in lubrication of the vagina, and in generating serous fluids. The present model proposes that the fluid released in a gush arises from the ventral wall of the vagina due to the presence there of increased surface area of mucosa, dilated arterioles, pressurized venous and lymphatic plexuses, and compression provided by muscle contraction during orgasm.

    Mapping Long Term Changes in Mangrove Cover and Predictions of Future Change under Different Climate Change Scenarios in the Sundarbans, Bangladesh
    (2018-05-22)
    Ghosh, Manoj Kumer
    ;
    Ground-based readings of temperature and rainfall, satellite imagery, aerial photographs, ground verification data and Digital Elevation Model (DEM) were used in this study. Ground-based meteorological information was obtained from Bangladesh Meteorological Department (BMD) for the period 1977 to 2015 and was used to determine the trends of rainfall and temperature in this thesis. Satellite images obtained from the US Geological Survey (USGS) Center for Earth Resources Observation and Science (EROS) website (www.glovis.usgs.gov) in four time periods were analysed to assess the dynamics of mangrove population at species level. Remote sensing techniques, as a solution to lack of spatial data at a relevant scale and difficulty in accessing the mangroves for field survey and also as an alternative to the traditional methods were used in monitoring of the changes in mangrove species composition, . To identify mangrove forests, a number of satellite sensors have been used, including Landsat TM/ETM/OLI, SPOT, CBERS, SIR, ASTER, and IKONOS and Quick Bird. The use of conventional medium-resolution remote sensor data (e.g., Landsat TM, ASTER, SPOT) in the identification of different mangrove species remains a challenging task. In many developing countries, the high cost of acquiring high- resolution satellite imagery excludes its routine use. The free availability of archived images enables the development of useful techniques in its use and therefor Landsat imagery were used in this study for mangrove species classification. Satellite imagery used in this study includes: Landsat Multispectral Scanner (MSS) of 57 m resolution acquired on 1st February 1977, Landsat Thematic Mapper (TM) of 28.5 m resolution acquired on 5th February 1989, Landsat Enhanced Thematic Mapper (ETM+) of 28.5 m resolution acquired on 28th February 2000 and Landsat Operational Land Imager (OLI) of 30 m resolution acquired on 4th February 2015. To study tidal channel dynamics of the study area, aerial photographs from 1974 and 2011, and a satellite image from 2017 were used. Satellite images from 1974 with good spatial resolution of the area were not available, and therefore aerial photographs of comparatively high and fine resolution were considered adequate to obtain information on tidal channel dynamics. Although high-resolution satellite imagery was available for 2011, aerial photographs were used for this study due to their effectiveness in terms of cost and also ease of comparison with the 1974 photographs. The aerial photographs were sourced from the Survey of Bangladesh (SOB). The Sentinel-2 satellite image from 2017 was downloaded from the European Space Agency (ESA) website (https://scihub.copernicus.eu/). In this research, elevation data acts as the main parameter in the determination of the sea level rise (SLR) impacts on the spatial distribution of the future mangrove species of the Bangladesh Sundarbans. High resolution elevation data is essential for this kind of research where every centimeter counts due to the low-lying characteristics of the study area. The high resolution (less than 1m vertical error) DEM data used in this study was obtained from Water Resources Planning Organization (WRPO), Bangladesh. The elevation information used to construct the DEM was originally collected by a Finnish consulting firm known as FINNMAP in 1991 for the Bangladesh government.

    Reinforced Behavioral Variability and Sequence Learning Across Species
    (Association for Behavior Analysis International (ABAI), 2012)
    Doolan, Kathleen

    Previous research shows that reinforcement of variable responding will facilitate sequence learning in rats (Neuringer, Deiss & Olson, 2000) but may interfere with sequence learning in humans (Maes & van der Goot, 2006). The present study aimed to replicate and extend previous research by assessing the role of behavioral variability in the learning of difficult target sequences across 3 species: humans (n = 60), hens (n = 18) and possums (n = 6). Participants were randomly allocated to one of three experimental conditions (Control, Variable, Any). In the Control conditions sequences were only reinforced if they were the target sequence, in the Variability conditions sequences were concurrently reinforced on a Variable Interval 60-s schedule if the just entered sequence met a variability criterion, and in the Any condition sequences were concurrently reinforced on a Variable Interval 60-s schedule for any sequence entered. The results support previous findings with animals and humans; hens and possums were more likely to learn the target sequence in the Variability condition, and human participants were more likely to learn the target sequence in the Control condition. Possible explanations for differences between the performance of humans and animals on this task will be discussed.

    A Review into Effective Classroom Management and Strategies for Student Engagement: Teacher and Student Roles in Today’s Classrooms
    (Redfame Publishing Inc, 2019-12)
    Franklin, Hayley
    ;
    A teacher's role encompasses far more than just imparting curricula outcomes to their students: they need to equip students with the necessary tools to experience social and academic success both inside the classroom and beyond it. Teachers need to empower students with the means to critically analyse the world around them in order to develop into critical independent thinkers. Students need to be proficient in utilising skills associated with higher levels of thinking, that will empower them with the ability to identify, analyse and evaluate the infinite volume of information available through our rapidly changing digital world. Just as teachers need to take responsibility for the various methods of teaching and instruction in the classroom, it is essential for students to take ownership of the learning process, to ensure future success in university environments, where sustained personal effort and metacognitive skills are fundamental to academic success. The object of the review of the literature surrounding the roles of teacher and student, effective classroom management strategies, and successful evidence-based teaching and learning pedagogies, is to assist new and experienced teachers in the promotion of a positive classroom experience for all.
