Involvement of fathers and siblings in home rehabilitation programmes of children with neuro-developmental delay: Insights from rehabilitation professionals in Bulawayo, Zimbabwe.
No full textIntroduction: Neuro-developmental delays (NDD) pose significant challenges for children and families, particularly in low-income settings with limited healthcare resources. Home rehabilitation programmes are essential in managing NDD, but the involvement of fathers and siblings remains under-researched. This study seeks to investigate the perspectives of rehabilitation professionals on the involvement of fathers and siblings in home rehabilitation programmes for children with NDD in Bulawayo, Zimbabwe.Participants and Methods: This qualitative exploratory study was conducted with 18 rehabilitation professionals from United Bulawayo Hospitals and Mpilo Central Hospital. Data were collected through focus group discussions (FGDs), which were transcribed, coded, and thematically analysed. The analysis focused on identifying themes related to the involvement of fathers and siblings in home rehabilitation for children with NDD.Results: Rehabilitation professionals emphasized the crucial role of fathers and siblings in home rehabilitation. Fathers were noted for providing emotional support and financial stability, while siblings contributed through social interactions and play therapy. Barriers to involvement included cultural norms, time constraints for fathers, and the emotional burden and limited understanding in siblings. These challenges highlighted the need for targeted interventions to better support family involvement in home rehabilitation programmes.Conclusion: Rehabilitation professionals believe that fathers and siblings play a vital role in the success of home rehabilitation for children with NDD. Overcoming cultural and practical barriers is essential to enhancing family participation. The study underscores the need for policy development and inclusive care models that engage all family members, particularly in low-income settings
First β -delayed γ -ray spectroscopy of <sup>109 </sup>Nb: Single-quasiparticle states with prolate shape in <sup>109</sup>Mo
Get PDFThe β-delayed γ-ray spectroscopy of 109Nb was performed to investigate the structure of 109Mo for the first time at the RIBF, Japan. Over one hundred transitions were assigned to 109Mo, of these two were from the known isomeric state, and a new 33.1 keV excited state below the isomeric state was identified. The multipolarities of the transitions depopulating the isomeric state were restricted considering the internal conversion coefficients and empirically recommended upper limits of transition strengths. The intrinsic gyromagnetic ratio of the isomeric-state band was extracted, and the rotational band of the ground state was identified. The configurations of the ground and isomeric states in 109Mo were assigned to the ν1/2+[411] and ν5/2+[413] orbitals, respectively, with prolate shape. From the logft analysis, the ground state in 109Nb and a new excited state in 109Mo with a small logft value were assigned to the π5/2+[422] and ν5/2+[402] orbitals, respectively. The assignments were supported by potential energy surface calculations using the configuration-constrained method with a triaxially deformed Woods-Saxon potential. Although the ν1/2+[411] orbital was successfully predicted as the ground state, the order of quasiparticle configurations for excited states was not reproduced. The neutron emission probability in 109Nb β-decay was evaluated to be 27(11)% utilizing the β-delayed γ rays of 109Tc and 108Mo.</p
Rhythm and Vigilance:Ethnographies of Surveillance and Time
No full textStudies of surveillance have emphasised how technology is used to control space. This innovative collection examines how new monitoring technologies are also affecting the experience of time.Drawing on Henri Lefebvre’s concept of rhythm, the book brings together ethnographic research from Europe, China and the US, to show how digital monitoring is transforming spatio-temporal relations across the Global North.As digital technologies continue to reshape the rhythms of life, this book makes a valuable contribution to both anthropology and surveillance studies

COVID-19 and Vaccine Hesitancy
No full textIn response to the outbreak of COVID-19 and its subsequent designation as a pandemic, vaccines against the virus were developed and gradually rolled out throughout the world (WHO, 2022). This article focuses upon the emergence of vaccine hesitancy and the likelihood of vaccination, specifically in the context of COVID-19. It is shown that vaccine hesitancy is not a new phenomenon but rather has been manifested to varying degrees since the advent of variolation in Europe in the 18th century. It is within this historical context that the concept of COVID-19 vaccine hesitancy should be regarded. The concept of vaccine hesitancy, introduced in order to understand why some people might potentially reject vaccines with the capacity to prevent or reduce the risk of preventable infection, is examined through a social psychological lens. Given its complexity and the inconsistent relationship between attitudes (e.g., vaccination hesitancy) and behavior (e.g., the likelihood that one will actually get vaccinated) (Marcinkowski & Reid, 2019), it is argued that a focus on vaccination likelihood (as a more reliable indicator of whether or not people will get vaccinated) is especially valuable (see Breakwell, Fino & Jaspal, 2021). Vaccination likelihood emerges as a result of many factors operating at distinct levels of analysis. Accordingly, a social psychological model of vaccine likelihood is presented that can enable both researchers and policymakers to understand its determinants
The Ideal Home for Lockdown Living
No full textThe exhibition designed and curated by Collectarium (Allyson Waller + Sophie Beard) in collaboration with Peter Maloney. The exhibition builds on the Lockdown Space Collection which invited people to post images/films online that shared how they had adapted, re-imagined, transformed and expanded their home environment during lockdown. For so many at this time everyday domestic space came under intense pressure to simultaneously function as the space for people to work, socialise, exercise, learn, create, entertain, play and escape. The exhibition reveals how people carried out makeshift and ad hoc interventions to their homes to generate new dynamic, flexible and multi-functional spaces. The once traditional enclosed spaces of privacy and safety now perform as the office, the gym, the school, the studio, the pub, the club, the campsite, the restaurant, the beach and spaces of the imagination. We invite you into the physical space of a house which spatially reframes and recontextualises the collection to critically reconsider the ideal home in our increasingly unsettled times. As part of the exhibition you will have the opportunity to engage with the collection and contribute to The Ideal Home Catalogue for Lockdown Living.

Investigation on formation, evolution, and performance impact of mixing layer in the zeotropic mixture ejector
No full textThis study investigates the fluid mixing mechanisms in zeotropic mixture ejectors, which are critical for enhancing the performance of ejector-based refrigeration cycles. A fluid dynamic model of an R245fa/R32 ejector is developed from the perspective of mixing layer evolution and validated against experimental data. The initiation and development of the mixing layer are analyzed under both subcritical and critical operating conditions, focusing on key characteristics such as the growth of the mixing boundary layer, mixing layer thickness, and non-mixing length. Results reveal that the mixing layer originates at the initial interface between the primary and secondary streams and gradually thickens along the flow direction. Its evolution is significantly affected by the operating mode: subcritical conditions lead to pronounced fluctuations in mixing layer thickness, whereas critical conditions maintain greater stability. Furthermore, the R245fa mass fraction influences the development of the mixing layer, which shows two distinct growth stages. Lower R245fa mass fraction slows the growth rate, while a more stable mixing boundary layer and an extended initial growth phase contribute to enhanced entrainment performance. This work establishes a systematic relationship between mixing layer evolution and ejector efficiency, offering a theoretical foundation for the design and optimization of zeotropic mixture ejectors.</p
Effect of Twisted Tapes on Swirling Flow Dynamics in Gas–Solid Two-Phase Flows for Natural Gas Hydrate Transportation
No full textThe discrete phase model (DPM) and the RNG k-ε turbulence model were employed to simulate the swirl flow behavior of hydrate transport in pipelines equipped with twisted tapes. The study analyzed the effects of various twisted tape parameters on the velocity field, turbulent dissipation, turbulent kinetic energy, and pressure distribution of hydrate particles. The results indicate that increasing the placement angle of the twisted tape enhances the tangential velocity near the pipe axis while reducing the axial velocity. Similarly, higher twisted tape configurations result in a further decrease in axial velocity. An increase in the number of twisted tapes leads to reductions in both tangential and axial velocities, and maximum speed increased by 18.2%. Larger placement angles of twisted tapes also intensify turbulence dissipation, with a more pronounced decay in turbulence intensity observed from the pipe wall to the axis. At section 8D, the turbulent kinetic energy increases by 60% with the increase in the height of the twisted tapes. Furthermore, as the number of twisted tapes increases, the disparity in turbulence strength between regions near the twisted tape and the pipe axis diminishes. The inner pipe pressure distribution is 360°/n rotation symmetrical distribution, and the twist tape is more, and the high pressure area is greater on the pipe section. The minimum pressure area is gradually close from the lee plane of the diversion strip to the position of the pipe axis. At section 65D, the pressure drop increases gradually with the increase in the orientation angle, and it increases by 36.8%.</p
