A gradual separation from the world: commentary on a qualitative exploration of existential loneliness in old age.

AIMS AND METHODS: Loneliness is a prevalent and significant issue. It has been identified as a particularly important physical and mental health risk for older people. This article critically explores and discusses a recent study that sought to qualitatively explore the lived experiences of existential loneliness in a large sample of older people living in retirement community contexts. FINDINGS: The data pointed to complex, multilayered challenges, often brought about by ageing, that give rise to unique experiences of existential loneliness for many older people. CONCLUSIONS: For clinical practitioners, understanding how older people experience existential loneliness is essential if we are to develop support mechanisms that compassionately and empathically respond to them.

"They want you to know who they really are inside of the old visage"-biographical storytelling as a methodological tool to explore emotional challenges in old age.

BACKGROUND: Growing older is often associated with resilience, contentedness and inner growth. Older people however are also at risk of confronting unique emotional challenges as a result of varied ageing-related experiences. By employing a biographical lens, we aim to introduce storytelling as a methodological tool to more holistically explore older people's emotional challenges and to improve their wellbeing. METHODS: Building upon theoretical understandings about the narrative construction of identity across the life span, we draw upon a qualitative study about older people's loneliness as an example to showcase the methodological value and feasibility of biographical storytelling. We aim to better understand the nuanced and sometimes painful emotional experiences that can be encountered alongside ageing. RESULTS: Findings from the qualitative study we showcase, highlight that unique emotional pains and the (in)ability to deal with such in old age could be deeply rooted in older people's earlier lives. These findings contextualise people's emotional challenges and needs within their identity, as a narrative thread that links their past, present and expected future. As such, our example study shows that emotional challenges in old age are not only ageing-related, but can be more fundamentally connected to disruptions to the ongoing flow of narrative identity construction. CONCLUSION: The highly retrospective and reflexive nature of these findings illustrates the methodological merit of biographical storytelling. We argue that the impact of biographical storytelling can go further than both conventional semi-structured narrative interviews and existing interventional tools. Instead, it is a particularly useful research methodology to explore human experiences and needs in the unique context of ageing. This methodological development thus provides an insightful analytical lens to explore how older people's earlier life experiences may be carried forward and confronted to shape their emotional stability in the present and future stages of their ageing lives. Beyond the methodological significance, we further demonstrate the benefits of empowering older people to reconstruct their ageing lives in the context of their biography.

Tracing the international arrivals of SARS-CoV-2 Omicron variants after Aotearoa New Zealand reopened its border.

In the second quarter of 2022, there was a global surge of emergent SARS-CoV-2 lineages that had a distinct growth advantage over then-dominant Omicron BA.1 and BA.2 lineages. By generating 10,403 Omicron genomes, we show that Aotearoa New Zealand observed an influx of these immune-evasive variants (BA.2.12.1, BA.4, and BA.5) through the border. This is explained by the return to significant levels of international travel following the border's reopening in March 2022. We estimate one Omicron transmission event from the border to the community for every ~5,000 passenger arrivals at the current levels of travel and restriction. Although most of these introductions did not instigate any detected onward transmission, a small minority triggered large outbreaks. Genomic surveillance at the border provides a lens on the rate at which new variants might gain a foothold and trigger new waves of infection.

Quantum Spin-1/2 Dimers in a Low-Dimensional Tetrabromocuprate Magnet.

This work describes a homometallic spin- 1 / 2 tetrabromocuprate adopting a bilayer structure. Magnetic-susceptibility measurements show a broad maximum centred near 70 K, with fits to this data using a Heisenberg model consistent with strong antiferromagnetic coupling between neighbouring copper atoms in different layers of the bilayer. There are further weak intralayer ferromagnetic interactions between copper cations in neighbouring dimers. First-principles calculations are consistent with this, but suggest there is only significant magnetic coupling within one direction of a layer; this would suggest the presence of a spin ladder within the bilayer with antiferromagnetic rung and weaker ferromagnetic rail couplings.

"We Are Good Neighbors, But We Are Not Carers!": Lived Experiences of Conflicting (In)dependence Needs in Retirement Villages Across the United Kingdom and Australia.

BACKGROUND AND OBJECTIVES: This study sought to qualitatively explore the lived experiences of 80 older people living in retirement villages across the United Kingdom and Australia. We focused on residents' narratives around the themes of independence/dependence. RESEARCH DESIGN AND METHODS: Qualitative semistructured interviews permitted in-depth exploration of how older people understood and experienced issues related to independence/dependence in the context of retirement living. RESULTS: Core themes identified strikingly different and often competing needs and narratives around independence/dependence. Of note was the fact that narratives and needs around independence/dependence frequently collided and conflicted, creating a sense of "us" and "them" in the retirement community. The primary source of such conflict was reflected by the fact that residents seeking a "prolonged midlife" often felt that frailer and more dependent residents were a burden on them and were not suited to an "independent living community." DISCUSSION AND IMPLICATIONS: Our findings are discussed in relation to the challenges such competing narratives create for retirement villages as living environments for a group of people who are far from homogenous.

'They're Going to Die at Some Point, but We're all Going to Die' - A Qualitative Exploration of Bereavement in Later Life.

This article reports on a qualitative study to investigate what bereavement means to older people. Drawing upon 80 in-depth interviews collected from eight British and Australian retirement communities, our study revealed that facing bereavement while ageing includes experiences of losing both others and the wholeness of the self. Core themes identified how the experience of losing others can be compounded by ageing-related challenges, undermining older people's defence from bereavement and frustrating their fundamental meaning and being. The older people's dynamic responses were also captured, highlighting the importance of supporting their agency to deal with the deeper pain of loss. By extending the concept of bereavement in later life, we also called for a more grief literate culture to mitigate the multifaceted and often deeper distresses of bereavement that older people may face alongside ageing.

Is Parental Attachment Security Contextual? Exploring Context-Specific Child-Parent Attachment Patterns and Psychological Well-Being in Taiwanese Youths.

Scant research to date has explored the possibility of context-specific variation in attachment security within a given relationship. In this paper, two cross-sectional studies were designed (1) to develop and validate context-specific attachment scales in Traditional-Chinese and (2) to explore variations in attachment security within a given parental relationship but between the contexts of sport and academics, relating them to global attachment patterns and indicators of psychological well-being. Results indicated that Taiwanese youth can and do perceive contextual variation within a given parental relationship. However, the relationship between such contextual variation and psychological outcomes was complex. Contextual variation may be a meaningful and useful way to explore and think about within-parent attachment fluctuation.

A Critical Exploration of Child-Parent Attachment as a Contextual Construct.

Bowlby's attachment theory has been employed as a broad and integrative framework to explore human wellness across a range of disciplines. Attachment theory has even been labelled one of the last surviving "grand theories" not to have been completely dismissed, replaced, or extensively reworked. However, despite the ubiquitous nature of some of the theory's fundamental tenets, there are always possibilities for new conceptual development, extension, and revision. In this paper, we critically explore the idea of "context-specific" attachment within parent-child relationships. We briefly outline critical assumptions and key areas of attachment and articulate potential rationale, conceptualization, and relevance of contextual attachment.

Fostering secure attachment: experiences of animal companions in the foster home.

This study sought to use attachment theory as a lens through which to explore children's relationships with animal companions in the context of long-term foster care. Inductive and deductive thematic analyses of longitudinal case study data from eight children and their foster families suggested (a) that children's relationships with animal companions satisfied attachment-related functions in their own right and (b) that animal companions also helped to soften perceptions of foster caregivers, facilitating opportunities for the development of closeness. Animals in the foster home may therefore play an important part in helping children to find and develop secure, warm, and loving relationships.

The physiological response to cold-water immersion following a mixed martial arts training session.

Combative sport is one of the most physically intense forms of exercise, yet the effect of recovery interventions has been largely unexplored. We investigated the effect of cold-water immersion on structural, inflammatory, and physiological stress biomarkers following a mixed martial arts (MMA) contest preparation training session in comparison with passive recovery. Semiprofessional MMA competitors (n = 15) were randomly assigned to a cold-water immersion (15 min at 10 °C) or passive recovery protocol (ambient air) completed immediately following a contest preparation training session. Markers of muscle damage (urinary myoglobin), inflammation/oxidative stress (urinary neopterin + total neopterin (neopterin + 7,8-dihydroneopterin)), and hypothalamic-pituitary axis (HPA) activation (saliva cortisol) were determined before, immediately after, and 1, 2, and 24 h postsession. Ratings of perceived soreness and fatigue, counter movement jump, and gastrointestinal temperature were also measured. Concentrations of all biomarkers increased significantly (p < 0.05) postsession. Cold water immersion attenuated increases in urinary neopterin (p < 0.05, d = 0.58), total neopterin (p < 0.05, d = 0.89), and saliva cortisol after 2 h (p < 0.05, d = 0.68) and urinary neopterin again at 24 h (p < 0.01, d = 0.57) in comparison with passive recovery. Perceived soreness, fatigue, and gastrointestinal temperatures were also lower for the cold-water immersion group at several time points postsession whilst counter movement jump did not differ. Combative sport athletes who are subjected to impact-induced stress may benefit from immediate cold-water immersion as a simple recovery intervention that reduces delayed onset muscle soreness as well as macrophage and HPA activation whilst not impairing functional performance.

Urinary myoglobin quantification by high-performance liquid chromatography: An alternative measurement for exercise-induced muscle damage.

This study investigated a means of quantifying urinary myoglobin using a novel reverse-phase high-performance liquid chromatography (RP-HPLC) method that is an alternative measure of exercise-induced muscle damage. It also investigated the effect of storage and alkalization on urinary myoglobin stability issues. An RP-HPLC method was validated by precision and repeatability experiments. Myoglobin stability was determined through spiked urine samples stored at various temperatures over an 8-week period using alkalization and dilution in a pH 7.0 buffer. The method was validated with urine collected from mixed martial arts fighters during a competition and training session. The method produced linearity from 5 to 1000 µg/ml (R(2) = 0.997), intra- and inter-assay coefficients of variation from 0.32 to 2.94%, and a lower detection limit of 0.2 µg/ml in the final dilution and 2 µg/ml in the original urine sample. Recovery ranged from 96.4 to 102.5%, myoglobin remained stable at 4 °C when diluted in a pH 7.0 buffer after 20 h, and a significant increase (P < 0.01) and an identifiable peak were observed following a mixed martial arts contest and training session. Storage length and conditions had significant effects (P < 0.05) on stability. The method's simplicity and noninvasive nature means it can be used as an alternative muscle damage assay following exercise and trauma.

Consciously identified attachment hierarchies: cognitive accessibility of attachment figure names as a function of threat primes in a lexical decision task.

Studies have linked the subliminal priming of threat-related words to heightened cognitive accessibility directed towards the names of identified attachment figures. The present study used a lexical decision task to examine the cognitive accessibility of names of individuals who formed part of participants' self-reported attachment hierarchies. We did not find support for heightened accessibility in relation to the names of (a) consciously identified attachment figures in general, (b) full-blown attachment figures, or (c) primary attachment figures. However, our data revealed that participants showed increased accessibility to mothers' names in response to threat primes. This effect was even identified in individuals who did not consider mothers to occupy a primary position in their attachment hierarchy. Results are discussed in the context of attachment system activation in early adulthood.

Full counting statistics in the self-dual interacting resonant level model.

We present a general technique to obtain the zero temperature cumulant generating function of the full counting statistics of charge transfer in interacting impurity models out of equilibrium from time-dependent simulations on a lattice. We demonstrate the technique with application to the self-dual interacting resonant level model, where very good agreement between numerical simulations using the density matrix renormalization group and those obtained analytically from the thermodynamic Bethe ansatz is found. We show from the exact form of counting statistics that the quasiparticles involved in transport carry charge 2e in the low bias regime and e/2 in the high bias regime.

Effect of a local perturbation in a fermionic ladder.

We study the effect of a local external potential on a system of two parallel spin-polarized nanowires placed close to each other. For single-channel nanowires with repulsive interaction we find that transport properties of the system are highly sensitive to the transverse gradient of the perturbation: the asymmetric part completely reflects the electrons leading to vanishing conductance at zero temperature, while the flat potential remains transparent. We envisage a possible application of this unusual property in the sensitive measurement of local potential field gradients.

Assessment of deviant arousal in adult male sex offenders with developmental disabilities.

Ten individuals, residing in a treatment facility specializing in the rehabilitation of sex offenders with developmental disabilities, participated in an arousal assessment involving the use of the penile plethysmograph. The arousal assessments involved measuring change in penile circumference to various categories of stimuli both appropriate (adult men and women) and inappropriate (e.g., 8- to 9-year-old boys and girls). This approach extends the existing assessment literature by the use of repeated measurement and single-subject experimental design. Data from these assessments were analyzed to determine if clear and informative outcomes were obtained. Overall, three general patterns of results emerged. Some participants showed differentiated deviant arousal or higher levels of arousal to specific inappropriate stimuli (deviant is a term used in the existing sex-offender literature to describe this type of arousal). Other participants showed undifferentiated deviant arousal, in which case they showed nonspecific arousal to inappropriate stimuli. The remaining participants showed no arousal to inappropriate stimuli but did show arousal to appropriate stimuli. Implications for assessment, treatment, and future directions are discussed.

An examination of multiple goals in children's physical education: motivational effects of goal profiles and the role of perceived climate in multiple goal development.

In this paper, I present data from two studies that sought to examine multiple achievement goals in the context of children's physical education (PE). Study 1 examined the links that multiple-goal profiles (i.e. mastery/performance-approach/performance-avoidance goals) for PE had with self-determined motivation, affective patterns and levels of extracurricular sporting activity in a sample of 193 Year 7 pupils. Results suggested that children endorsing high mastery/high performance-approach/high performance-avoidance, high mastery/high performance-approach/low performance-avoidance, or high mastery/ low performance-approach/low performance-avoidance profiles typically exhibited the most adaptive motivational responses. In contrast, children endorsing a low mastery/high performance-approach/high performance-avoidance profile typically experienced more maladaptive motivational outcomes. Study 2 examined the development of multiple achievement goals over two terms of PE in conjunction with retrospective perceptions of the motivational climate in the sample. The results of analysis of variance suggested that children exposed to a consistent high mastery/low performance climate experienced decreased performance-avoidance goals and maintained high levels of mastery goals for PE. In contrast, children exposed to a consistent low mastery/high performance climate experienced increased performance-avoidance goals and decreased mastery goals for PE.

Spectrum and correlation functions of a quasi-one-dimensional quantum Ising model.

For a model of weakly coupled quantum Ising chains we outline the phase diagram and establish that well below the transition line the system has a remarkably one-dimensional spectrum. We study the dynamical magnetic susceptibility and find a very rich spectrum with several modes corresponding to a fundamental particle and its bound states. The approach is based on the Bethe ansatz and the random phase approximation applied to the interchain exchange.
