Unveiling the potential of diffusion model‑based framework with transformer for hyperspectral image classification
Get PDFHyperspectral imaging has gained popularity for analysing remotely sensed images in various fields such as agriculture and medical. However, existing models face challenges in dealing with the complex relationships and characteristics of spectral–spatial data due to the multi-band nature and data redundancy of hyperspectral data. To address this limitation, we propose a novel approach called DiffSpectralNet, which combines diffusion and transformer techniques. The diffusion method is able to extract diverse and meaningful spectral–spatial features, leading to improvement in HSI classification. Our approach involves training an unsupervised learning framework based on the diffusion model to extract high-level and low-level spectral–spatial features, followed by the extraction of intermediate hierarchical features from different timestamps for classification using a pre-trained denoising U-Net. Finally, we employ a supervised transformer-based classifier to perform the HSI classification. We conduct comprehensive experiments on three publicly available datasets to validate our approach. The results demonstrate that our framework significantly outperforms existing approaches, achieving state-of-the-art performance. The stability and reliability of our approach are demonstrated across various classes in all datasets

Constructions of babyhood among baby room leaders in the UK
Get PDFThe research presented in this article scrutinises how baby room leaders construct babyhood and how this impacts their practice. Our research feeds into a growing body of research that challenges the dominant developmentalist paradigm in early childhood education and care (ECEC) and instead highlights possibilities for self-determination, agency and reciprocity in the baby room. Through an inductive thematic analysis applied to 15 interviews with baby room leaders across the UK, we consider how baby room leaders construct babies as receptacles of care, find joy in being needed and make sense of babies’ learning through developmental checklists and milestones. We pay particular attention to the questions that emerge when we consider baby room educators’ joy in being needed: how this can reinforce a perception of babies as completely dependent while simultaneously highlighting their agency and the extent to which their actions shift the emotional landscape of those around them. Our research calls for more provocation, reflection and problematisation that specifically focuses on baby pedagogies and the constructions of babyhood on which these pedagogies are founded
‘We’re not that gullible!’ Revealing dark pattern mental models of 11-12 year-old Scottish children
Get PDFDeceptive techniques known as dark patterns specifically target online users. Children are particularly vulnerable as they might lack the skills to recognise and resist these deceptive attempts. To be effective, interventions to forewarn and forearm should build on a comprehensive understanding of children’s existing mental models. To this end, we carried out a study with 11-12 year old Scottish children to reveal their mental models of dark patterns. They were acutely aware of online deception, referring to deployers as being ‘up to no good’. Yet, they were overly vigilant and construed worst-case outcomes, with even a benign warning triggering suspicion. We recommend that rather than focusing on specific instances of dark patterns in awareness raising, interventions should prioritise improving children’s understanding of the characteristics of, and the motivations behind, deceptive online techniques. By so doing, we can help them to develop a more robust defence against these deceptive practices
Validity and reliability of torso- versus waist-worn inertial measurement units in the assessment of vertical jumps
Get PDFThe aim of the current study was to compare the reliability and validity of jump variables determined from torso- and waist-worn inertial measurement units (IMU) in comparison to force platform measures. Twenty-seven students-athletes completed eight countermovement (CMJ) and squat jumps (SJ) on a force platform with IMUs mounted on the pelvis and torso. Variables including jump height and phase-specific duration, impulse and power were calculated from force platform and both IMUs independently. Considering both IMU locations, the coefficients of variation (CV) observed for all CMJ variables were ≤ 2.5 % larger than the force platform with the exception of concentric impulse with the torso-worn worn IMU (6.9 %). Differences in CVs observed between IMU and force platform variables appeared greater in the SJ. For velocity-derived jump height and concentric impulse from both IMU placements, and torso-worn IMU mean power, CVs were > 2.5 % larger than the force platform. Both IMU placements overestimated jump height determined by flight time (+22 to +35 %) and underestimated jump height determined by take-off velocity (−10 to −18 %). In conclusion, the reliability of IMU metrics was largely comparable to the force platform. However, systematic bias was observed for most metrics. Practitioners should exercise caution if seeking to model jump performance with IMUs
A phenomenological enquiry into the experience of western women who found a significant other after a course of psychotherapy
Get PDFWhilst relationship therapy is a thriving practice (van Deurzen & Iacovou, 2013; Barker, 2015; Charura & Paul, 2015), no research has focused on women who found a significant other during or after a course of psychotherapy. This study explored the experience of women who overcome their previous difficulty entering healthy romantic relationships during or after attending a course of psychotherapy in any modality. The focus was on uncovering what the participants believe made the difference for them. Seven women gave an account of their experience via semi-structured interviews. The data analysis was performed using a phenomenological-interpretative analysis (IPA) (Smith et al., 2009). Four superordinate themes emerged from the analysis of the seven transcripts, with fifteen associated themes:
1. Self-Love and four associated themes.
The results point towards marked and varied changes in feelings towards oneself.
2. Self-Awareness and four associated themes.
The results show a new understanding of the participants’ worldview.
3. Sense of Agency
The results indicate that the participants have gained an ability to act on their new understandings to shape their lives.
4. Role in the family and three associated themes.
The results suggest that unpacking past events helped support the participants’ change.
Recommendation: The counselling psychology, the psychotherapy world, and the public could benefit from putting psychotherapy forward as a place women can consider going when struggling to form healthy romantic relationships
Digital stories - individual meaning-making for heritage tourism
No full textExperiential learning emphasises student-centred, collaborative and inclusive methods that are often difficult to implement in traditional teaching environments. In order to maximise the benefits of experiential learning, there needs to be a critical focus on developing creative pedagogies and innovative approaches. Student-led projects offer opportunities for students to engage in experiential learning (McGovern, 2018). Heritage, a complex and multi-dimensional concept, is often difficult for students to conceptualise and contextualise. Heritage evolves over time, is open to different interpretations and involves different stakeholders in its conservation and tourism development. The integration of digital stories as a summative assessment helps to enrich students' critical understanding of the intricate dynamics involved in utilising and promoting heritage in tourism, compared to more conventional assessment methods such as reports and essays. Through the use of digital storytelling students are encouraged to personalise and contextualise key concepts related to heritage, thereby enhancing their independent and reflective approaches to knowledge construction and co-construction
The effect of interpersonal conflict on employee behaviors: the role of perception of politics and competence uncertainty
Get PDFPurpose
Conflict, between individuals and groups, in organizations is a common phenomenon and can have varied implication for the employee and the organization. This paper aims to determine whether experiencing interpersonal conflict drives employees to engage in prosocial behavior (prohibitive voice) and antisocial behavior (interpersonal deviance). Using Stressor–Emotion Model, Uncertainty Management Theory and Impression Management Motives, this study examines the relationship and explores competence uncertainty as a mediator and perception of politics as a moderator.
Design/methodology/approach
This study uses a cross-sectional design where data collected is from 386 employees working in nine different public sector enterprises in India. Structural equation modeling using SPSS AMOS was used to analyze the hypothesized relationships.
Findings
The results show that interpersonal conflict leads to both prohibitive voice behavior and interpersonal deviance. However, the mediating role of competence uncertainty is valid only for the effect of conflict on interpersonal deviance. Also, the perception of politics strengthens the positive relationship between interpersonal conflict and competence uncertainty.
Originality/value
To the best of the authors’ knowledge, this is one of the first empirical studies to have validated prosocial and antisocial work behavior as outcomes of interpersonal conflict. Again, this is one of the first few studies to examine the mechanism through which interpersonal conflict impacts interpersonal deviance
The lived experience of non-religious healthcare chaplains entering faith-based healthcare chaplaincy teams
Get PDFThis research explores the experiences of non-religious (specifically humanist) healthcare chaplains within traditionally faith-based chaplaincy teams in the UK. While the primary focus is on non-religious chaplaincy, faith-based chaplains views and experiences are also important as a point of reference, and to provide a broader understanding, aiming to contribute to a deeper knowledge of healthcare chaplaincy in the UK. Using a mixed-methods approach, the study includes a qualitatively dominated online survey (44 non-religious, 64 faith-based) analysed with descriptive statistics and Reflexive Thematic Analysis (RTA). Additionally, semi-structured interviews were conducted with 11 non-religious and 11 faith-based chaplains, also analysed using RTA.
Findings show that non-religious chaplains face societal and recruitment challenges, advocating for secular perspectives while feeling excluded from roles requiring religious elements. Faith-based chaplains similarly report challenges in mutual understanding and respect from non-religious counterparts. Non-religious chaplains are often in volunteer roles, while faith-based chaplains occupy paid and leadership positions, highlighting the need for equitable access to opportunities.
Both faith-based and non-religious chaplains aim to provide spiritual and emotional support, upholding values of professionalism, inclusivity, and empathy. Non-religious chaplains work to bridge religious and secular ethics. They focus on existential support from a secular perspective. Faith-based chaplains see their work as a divine calling, incorporating religious rituals.
Despite differences, the majority of both chaplaincy groups are optimistic about evolving, inclusive chaplaincy models. The findings underscore a mutual need for understanding and recognition of each other’s roles within the chaplaincy field.
The thesis concludes that understanding and collaboration between non-religious and faith-based chaplains are vital for a diverse chaplaincy profession. Equitable opportunities, recognition, and comprehensive training are essential to address healthcare service-users’ spiritual needs effectively
Desire Lines [Installation and performance]
No full textDesire Lines was commissioned by South Bank Centre, London for the Winter Lights Festival 2024.
The piece developed on previous works in collaboration with artist Nathaniel Rackowe ((Un)touched 2016-2020, (De)figured 2018-19), specifically the aspect of light use in relation to the dancers and the audience. This dialogue expresses our concerns on configurations that announce complexities between each aspect.
The installation consists of nine cubes of light placed within nine trees along the riverbank, incorporating a light sequence to flow across all the nine trees to create a single 60m dynamic installation. This horizontal flow echoes the movement of people as they walk down the Southbank; the movement plays with this sense of journey. The research explores how action and the timing of the light sequence draws attention to the energy of the movement. Our questions - how nature / urban intersection with the trees becomes part of the sculpture; how we define space and form through colour and action through time; how transitory / ephemeral spaces can change or disappear through action and stillness
