Rank versus Romance: The Relationship of Class and Courtship in Burney\u27s Evelina

Frances Burney explores the complex intersection of class and courtship in her novel Evelina as her heroine enters adulthood and consequently the marriage market. Throughout the novel, the heroine, Evelina, is pursued or courted by men as she is situated in three distinct class settings. First, she enters society in a respectable middle class setting, then a lower-middle class setting, before finally settling in an upper class setting and gets married. This development in the novel represents the significant affect class has on relationships in the 18th century. Ultimately, Burney communicates how a marriageable woman’s social and economic status clearly correlates with the level of respect she is given by suitors

Westerlund 1 as a Template for Massive Star Evolution

With a dynamical mass M_dyn ~ 1.3x10e5 M_sun and a lower limit M_cl>5x10e4 M_sun from star counts, Westerlund 1 is the most massive young open cluster known in the Galaxy and thus the perfect laboratory to study massive star evolution. We have developed a comprehensive spectral classification scheme for supergiants based on features in the 6000-9000A range, which allows us to identify >30 very luminous supergiants in Westerlund 1 and ~100 other less evolved massive stars, which join the large population of Wolf-Rayet stars already known. Though detailed studies of these stars are still pending, preliminary rough estimates suggest that the stars we see are evolving to the red part of the HR diagram at approximately constant luminosity.Comment: To be published in Proceedings of IAU Symposium 250: Massive Stars as Cosmic Engines, held in Kaua'i (Hawaii, USA), Dec 2007, edited by F.

Pictures are necessary but not sufficient: Using a range of visual methods to engage users about school design

It has been argued by both educationalists and social researchers that visual methods are particularly appropriate for the investigation of people's experiences of the school environment. The current and expected building work taking place in British schools provides an opportunity for exploration of methods, as well as a need to establish ways to achieve this involvement of a range of school users, including students. This article describes a consultation that was undertaken in a UK secondary school as part of a participatory design process centred on the rebuilding of the school. A range of visual methods, based on photographs and maps, was used to investigate the views of a diverse sample of school users, including students, teachers, technical and support staff and the wider community. Reported here is the experience of using these tools, considering the success of different visually-based methods in engaging a broad cross section of the school community and revealing useful information. Using a range of visual methods allows a complex, but coherent, understanding of the particular school environment to be constructed and developed. It is further argued that such a range of visual and spatial methods is needed to develop appropriate understanding. The study, therefore, contributes to knowledge about specific visual research methods, appreciation of the relationship between tools, and a general methodological understanding of visual methods' utility for developing understanding of the learning environment

Synthesis and study of frustrated oxide and mixed anion materials

Mixed anion systems, such as oxynitrides and oxyfluorides, are an emerging class of interesting materials. The lower stability of mixed anion systems in comparison to oxide materials has had the consequence that this area of materials research is relatively less well explored. However, the development of new synthesis techniques has resulted in the preparation of many new mixed anion systems and so a detailed understanding of their structure and how this relates to their electronic and magnetic properties is necessary. Within this Thesis, several oxide, oxynitride and oxyfluoride systems are investigated with a particular focus on the magnetic behaviour of materials based on geometrically frustrated pyrochlore and kagome lattices. The Lu2Mo2O7 pyrochlore contains a geometrically frustrated network of vertex sharing Mo4+ (d2 S = 1) tetrahedra. Here, the solid state synthesis of Lu2Mo2O7−x is reported along with a discussion of the coexistence of two cubic pyrochlore phases that has been discovered in samples synthesised at 1600 ◦C. Powder neutron diffraction and thermogravimetric analysis have revealed that this two-phase behaviour originates from a miscibility gap between stoichiometric Lu2Mo2O7 and oxygen deficient Lu2Mo2O6.6. Magnetic susceptibility and muon spin relaxation measurements support the formation of a geometrically frustrated spin glass ground state in Lu2Mo2O7 with a spin freezing temperature Tf ∼ 16 K. Low temperature neutron diffraction has confirmed the absence of long range magnetic order and magnetic diffuse neutron scattering data have indicated the presence of competing nearest and next nearest neighbour antiferromagnetic exchange interactions in the spin glass state. The magnetic heat capacity of Lu2Mo2O7 follows a T2-dependence at the low temperatures, indicating that Lu2Mo2O7 is another rare example of an unconventional, topological spin glass, which is stable in the absence of significant chemical disorder. The magnetic properties of the oxygen deficient pyrochlore phase Lu2Mo2O6.6 are qualitatively similar to those of Lu2Mo2O7, but an increase in the spin freezing temperature Tf ∼ 20 K suggests that oxygen-vacancy disorder in Lu2Mo2O6.6 favours the onset of a glassy state at higher temperatures and enhances the degree of frustration. Oxynitride pyrochlores with the ideal composition R2Mo2O5N2 (R = rare earth) contain Mo5+ d1 S = 1 2 cations on the frustrated pyrochlore lattice and are thus ideal candidates to support exotic magnetic ground states. Here, the synthesis of oxynitride pyrochlores of the Lu2Mo2O7 system by thermal ammonolysis is discussed alongside powder neutron diffraction and susceptibility data that show no evidence for long range magnetic order and an absence of spin freezing down to at least 2 K despite the persistence of strong antiferromagnetic exchange (θ = −120 K). A comparison of the magnetic diffuse neutron scattering between the spin glass state of Lu2Mo2O7 and the oxynitride is given, which suggests that the majority of the magnetic scattering in the oxynitride system is inelastic. In addition, low temperature magnetic heat capacity shows an absence of magnetic phase transitions and a continuous density of states through a T-linear dependence down to 500 mK. [NH4]2[C7H14N][V7O6F18], diammonium quinuclidinium vanadium(III,IV) oxyfluoride or DQVOF, is a kagome bilayer system with a geometrically frustrated two-dimensional kagome network of V4+ d1 S = 1 2 cations and V3+ d2 S = 1 cations between the kagome layers. Here, low temperature magnetisation and heat capacity data are presented, which demonstrate that the interplane V3+ d2 cations are well decoupled from the kagome layers at low temperatures such that DQVOF is a good experimental realisation of a S = 1 2 kagome antiferromagnet. Despite significant antiferromagnetic exchange (θ = −60 K) within the kagome planes, muon spin relaxation data have confirmed the absence of spin freezing and the persistence of internal field fluctuations that are intrinsic to the kagome layers down to temperatures of 40 mK. The low temperature heat capacity of the V4+ kagome network follows T-linear behaviour down to the 300 mK, highlighting the absence of a spin gap in the low energy excitation spectrum of DQVOF. The low temperature magnetic study of DQVOF presented here thus strongly supports the formation of a gapless quantum spin liquid phase. In the final results chapter, a discussion of the anion ordering principles in oxynitride systems is given. A high temperature, high resolution neutron diffraction study of the oxynitride perovskite SrTaO2N has revealed that the partial anion order that results in segregated Ta-N zig-zag chains is stable up to 1100 ◦C. Furthermore, these anion ordering principles are extended to the d1 perovskite oxynitrides RVO2−xN1+x (R = La, Nd, Pr) in a variable temperature neutron diffraction study, which confirms that the anion chain ordering discovered in d0 SrTaO2N is robust to electron doping. The R = La analogue also provides an interesting example of a rhombohedral oxynitride perovskite phase which coexists with an orthorhombic phase over the 4−300 K temperature range of the neutron diffraction study

Do attachment-related differences in reflective functioning explain associations between expressed emotion and youth self-harm?

Youth self-harm is associated with poor health outcomes and attempted and completed suicide. Associations exist between self-harm and expressed emotion (EE), attachment insecurity, and reflective functioning (RF), but these associations are poorly understood. This study evaluates a mediation model in which perceived caregiver EE (pEE) exerts an indirect effect on youth self-harm through attachment insecurity and RF uncertainty. 461 participants aged 16–24 years completed an online survey. Statistical analyses revealed significant direct effects of pEE on attachment insecurity, and of RF uncertainty on self-harm; however, some direct effects were specific to pEE from female caregivers, and attachment insecurity in youth relationships with female caregivers. A significant direct effect of pEE on self-harm was found for pEE from male caregivers only. Significant indirect effects of pEE on self-harm through attachment anxiety and RF uncertainty were found only in relation to female caregivers. The findings encourage family-, attachment-, and mentalization-based approaches to preventing and treating youth self-harm, with a recommendation that caregivers are given adequate support, education, and skills-based training following youth disclosures of self-harm.

Exploration of the role of attachment in the relationship between trauma and distress in psychosis

Background: Attachment literature indicates attachment status is related to trauma with associations between early trauma and insecure attachment. Links between psychosis and trauma have been established within the literature; however the precise nature of this relationship is still not fully understood. A systematic review was carried out to assess the state of the evidence pertaining to psychosis and attachment. Associations between insecure attachment and psychotic symptoms were identified. Other psychological correlates such as perceived parental care, attachment to services and interpersonal problems were found to relate to insecure attachment status. However due to the early stage of this area of research, small clinical sample sizes and heterogeneity of correlates investigated, firm conclusions cannot currently be drawn. Aim: The aim of this study was to investigate the relationship between trauma, attachment, reflective functioning (RF) and distress for people with psychosis with a view to further understanding these links and the clinical implications. Method: Participants with a diagnosis of psychosis were recruited and measures were completed with the principle investigator pertaining to trauma, attachment and distress in psychosis. Results: The majority of the sample reported insecure attachment and low RF and there were high levels of general, and more specifically, interpersonal trauma within the sample. Results indicated that early interpersonal trauma was associated with higher levels of emotional distress. Exploratory mediation analyses implicated anxious attachment in mediating the relationship between interpersonal trauma and distress. Discussion: The results indicate the need to consider early trauma histories and specifically interpersonal trauma and attachment in the context of emotional distress for people experiencing psychosis. Incorporating trauma and attachment based therapeutic approaches for people with psychosis is as relevant as it is for other trauma populations, where these approaches may be more routinely drawn on for formulation and treatment. Limitations of the methodological approach are considered along with suggestions for future research

How Long Should a Healthcare Practitioner Feel for a Pulse- A Literature Review

Assessing the vital signs of a patient is a fundamental technical skill that is routinely performed by healthcare practitioners and can help to indicate whether a patient is at risk of deteriorating. Palpating the peripheral pulse is frequently seen as a simple task when undertaking the assessment of vital signs and, often, little thought may be given to the amount of time that healthcare practitioners attribute to this task. Nursing undergraduate students are regularly taught that a minute is the ideal amount of time that a pulse should be palpated, however, in practice this is sometimes reduced to 15 or 30 seconds to save time. This article explores how much time the healthcare practitioner should palpate the pulse to achieve an accurate reading by examining the available literature

Heart-beat perception, panic/somatic symptoms and anxiety sensitivity in children

There is considerable evidence implicating heart-beat perception (HBP) accuracy and anxiety sensitivity (AS) in the development of panic in adults. However, to date there have been no studies exploring the association between HBP, AS and childhood panic/somatic symptoms. Seventy-nine children aged 8 to 11 years completed a mental tracking paradigm (Psychophysiology 18 (1981) 483) to assess HBP, the Children’s Anxiety Sensitivity Index (J Clin Chil Psychol 20 (1991) 162) and the Screen for Childhood Anxiety Related Emotional Disorders (J Am Acad Child Adoles Psych 38 (1999) 1230). Those with good HBP (n = 7, 9%) had significantly higher panic/somatic symptoms (t = -1.71, P < 0.05), and AS (t = -2.16, P < 0.02) than those with poor HBP. There were no effects of age, sex or BMI on HBP. Those with high levels of panic/somatic symptoms were seven times more likely to have good HBP and had AS scores 1 S.D. higher than the remainder of the sample. Multivariate analyses revealed that these two phenotypes had independent associations with high panic/somatic symptoms. These results extend the literature on HBP and panic and suggest that in children, as in adults, increased panic/somatic symptoms are associated with enhanced ability to perceive internal physiological cues, and fear of such sensations

Teaching during COVID-19: Relational-Cultural Theory in the Online Classroom

The sudden conversion from face-to-face to online instruction in Spring semester 2020 due to the COVID-19 pandemic was unprecedented. During this time instructors in helping professional training programs were engaged in the duality of being impacted in various degrees while simultaneously training students to assist clients in dealing with the resulting stress and emotional impact. Relational-Cultural Theory (RCT) is a framework that can be used within online counselor education to consider the impact of the larger socio-cultural context on student learning, prioritizing fostering relational connections. In this article, online teaching approaches aligned with the video conferencing tool, Zoom, are described
