Beyond the pandemic pedagogy of managerialism: exploring the limits of online teaching and learning
No full textThis book analyses how growing managerialism and the marketisation of higher education has undermined educational standards and pedagogical integrity. Specifically, it provides a thorough critique of how the pandemic, and the move to online learning and MOOCs, has reinforced these developments. The book outlines the limits of new managerialism, which is replacing critical mass with a culture of compliance in higher education.
Employing an ethnographic approach, the book explores the impact of the sudden shift in teaching delivery from in-person to online for example, the changing role of the PhD supervisor during the pandemic, and the impact on students’ willingness to engage and their (in)visibility in the classroom, and further considers how these impact class interactions, social relationships and learning. Ultimately, this book argues that the COVID-19 pandemic exposed the limits of marketisation of education and revealed the distorted managerial response to acrisis
A Bergsonian analysis of time in qualitative research: understanding lived experiences of street homeless people in Moscow
Get PDFUnderstanding of how ‘time’ is experienced is essential for doing qualitative research. This article explores how time seemingly stands still, speeds up, slows down, rewinds and fast-forwards for the participants in our qualitative investigations. Drawing upon interview data with street homeless people in Moscow, Russia, this article examines the ways in which time is contextualized and used by research participants to make sense of their everyday experiences and important events in their lives. There is a tendency to understand time by measuring it, rather than seeing it as something within which lived experience happens and qualitative research is carried out. Drawing on Bergson’s conception of time as duration, this article examines the ways in which time can be distinctively used and understood within qualitative research
At whose cost? Racialised differences in how domestic violence and sexual violence advocates adapted to COVID-19
No full textMuch of the research on COVID-19 and violence against women and girls (VAWG) has focused on the impacts on victim-survivors or on organisations offering support. This qualitative study aimed at documenting the coping strategies of, and the impacts on, support workers, specifically domestic and sexual violence advocates (independent domestic violence advisor [IDVA] and independent sexual violence advisors [ISVA]), in two London based organisations. The findings revealed a double load of supporting others while coping with the impacts of the pandemic on themselves and their families. An unanticipated but revealing finding was that the conjunction of the pandemic and the Black Lives Matter movement made visible and visceral the daily work that Black women do to manage everyday racism, including in the VAWG sector. For these women ‘returning to normal’ was an unwelcome and unacceptable prospect, making anti-racism work in the VAWG sector an urgent priority
A hierarchical security event correlation model for real-time threat detection and response
Get PDFAn Intrusion detection system (IDS) performs post-compromise detection of security breaches whenever preventive measures such as firewalls do not avert an attack. However, these systems raise a vast number of alerts that must be analyzed and triaged by security analysts. This process is largely manual, tedious and time-consuming. Alert correlation is a technique that reduces the number of intrusion alerts by aggregating alerts that are similar in some way. However, the correlation is performed outside the IDS through third-party systems and tools, the IDS has already generated a high volume of alerts. These third-party systems add to the complexity of security operations. In this paper, we build on the highly researched area of alert and event correlation by developing a novel hierarchical event correlation model that promises to reduce the number of alerts issued by an Intrusion Detection System. This is achieved by correlating the events before the IDS classifies them. The proposed model takes the best of features from similarity and graph-based correlation techniques to deliver an ensemble capability not possible by either approach separately. Further, we propose a correlation process for events rather than alerts as is the case in current art. We further develop our own correlation and clustering algorithm which is tailor-made to the correlation and clustering of network event data. The model is implemented as a proof of concept with experiments run on standard Intrusion detection sets. The correlation achieved 87% data reduction through aggregation, producing nearly 21,000 clusters in about 30 seconds
The social construction of professional counselling practice in UK embedded higher education counselling services: a Foucauldian discourse analysis of practitioner perspectives
Get PDFMost UK universities provide Embedded Higher Education Counselling Services (EHECS) as part of their student support offer. However, a wealth of theory based clinical literature belies a long-standing deficiency of empirical research within the UK student counselling sector. Recent research attention concerned with standardised outcome measurement, while important in justifying the value of such counselling services, may nevertheless fail to clarify unique aspects of practice in this context. A social constructionist research framework is advanced to elucidate how counselling practitioners construct the role and functions of their work in EHECS. Semi-structured interviews were undertaken with six student counsellors working across UK universities and the transcripts were analysed using Foucauldian Discourse Analysis (FDA). The study identified four dominant discourses: Academic achievement, Life-stage, Mental-health crisis and Professional counselling practice which were seen to influence the counsellor role as they manifested through a series of sub-discourses including, the Precedence of educational attainment sub-discourse, the Loco-parentis sub-discourse and the Risk-vulnerability sub-discourse. Student counselling was broadly constructed as a highly flexible, time-limited psycho-social intervention aiming to facilitate academic engagement while concurrently attending to the perceived developmental needs of student-clients. This may contrast with the expectations of students as well as other institutional stakeholders with implications for practice, supervision and training

Introduction – Partition and the South Asian diaspora: exploring (inherited) memories and creative practices of remembering
No full textThis short piece introduces the special issue ‘Partition and the South Asian diaspora: exploring (inherited) memories and creative practices of remembering’. This issue was conceived at the juncture of intersecting commemorations of key historical events – 1947 Partition of British India, 1971 Bangladesh independence and 1972 exodus from Uganda – in South Asia and its diasporas. By bringing together articles focused on practices of commemorating these events, we propose that studying entangled memories of Partition and its associated events in the diaspora provides a distinct perspective, both in terms of creative and cultural practices of remembering and in terms of the construction of diasporic identities and belongings
Impact of hole scavengers on efficient photocatalytic hydrogen production
No full textHydrogen is one of the most promising alternative energy resources to replace fossil feedstocks, with so‐called “green” hydrogen, derived by water splitting (WS) using renewable electricity or sunlight, the most sustainable. Photocatalytic hydrogen production, in which sunlight is the sole energy input, has been extensively studied, and requires the creation of photogenerated excitons (through irradiation of semiconductors) and their transport to aqueous media. Chemical scavengers, notably electron donating molecules, are widely used to quench photogenerated holes and thereby suppress exciton recombination which otherwise limits the hydrogen yield. Despite their prevalence, the role and significance of such scavengers (also termed sacrificial agents) in photocatalytic WS remains poorly understood, hindering their rational selection. This review focuses on the importance of electron donors in photocatalytic WS, and their participation in the reaction mechanism

In an age of viruses and hackers, electronic eavesdropping, and electronic fraud on a global scale, security is paramount. The purpose of this book is to provide a practical survey of both the principles and practice of cryptography and network security. The first part of the book explores the basic issues to be addressed by a network security capability and provides a tutorial and survey of cryptography and network security technology. The latter part of the book deals with the practice of network security, covering practical applications that have been implemented and are in use to provide network security
How appraisals of an in-group's collective history shape collective identity and action: evidence in relation to African identity
Get PDFThis research tested the impact of how group members appraise their collective history on in-group identification and group-based action in the African context. Across three experiments (Ns = 950; 270; and 259) with Nigerian participants, we tested whether the effect of historical representations–specifically the valence of the in-group’s collective history–on in-group engagement, in turn, depends on whether that history is also appraised as subjectively important. In Study 1, findings from exploratory moderated-mediation analyses indicated that the appraised negative valence of African history was associated with an increase in identification and group-based action when African history was appraised as unimportant (history-as-contrast). Conversely, the appraised positive valence of African history was also associated with an increase in identification and group-based action when African history was also appraised as important (history-as-inspiration). Studies 2a and 2b then orthogonally manipulated the valence and subjective importance of African history. However, findings from Studies 2a and 2b did not replicate those of Study 1. Altogether, our findings suggest that the relationship between historical representations of groups and in-group identification and group-based action in the present is more complex than previously acknowledged
