Capturing free-roaming dogs for sterilisation: data from a multi-site study in Goa, India
No full textSterilisation and rabies vaccination programs seek to manage free-roaming domestic dog (Canis familiaris) populations with the aim to reduce inter-species disease transmission and conflicts. As effective, permanent, remotely-administered options are not yet available for sterilisation, and oral vaccination is not yet commonly used; free-roaming dogs are typically captured for these interventions. To characterise the dynamics of free-roaming dog capture for sterilisation, we collected location and demographic data from six sterilisation campaigns conducted in Goa, India between 2020 and 2021 by the Worldwide Veterinary Service. These data described the daily success of catching teams during the sterilisation campaigns. Surveys of the free-roaming dog population were conducted prior to, during, and after the campaigns in five sites, documenting sterilisation status of dogs sighted. These data were used to infer daily sterilisation coverage for each study site. The associated paper demonstrates how dog capture varied with landcover type and distance from roads. The paper characterises how the reduction in entire (non-sterilised) dogs throughout intensive capture-sterilise-release programs reduces the number of dogs caught per day over time. These findings can be used to more-accurately model interventions in free-roaming dog populations and better understand their impacts. This will help to plan how to most efficiently distribute and make the best use of limited resources.Three files are shared. We are unable to share point locations due to privacy restrictions.
File 1 includes data used for landcover type and distance from roads analysis; each row represents a dog capture event.
File 2 includes data used for model 1; each row represents results of a dog population survey and number of sterilisations performed.
File 3 includes data for model 2; each row represents a day when catching occurred in the morning and afternoon for a particular site
Managing free-roaming domestic dog populations using surgical sterilisation: a randomised controlled trial
No full textFree-roaming domestic dogs (FRDs) are among the most abundant carnivores on earth and have coexisted with humans for over 15,000 years, yet increases in negative interactions and the transmission of zoonotic diseases, precipitates calls for population management. Despite significant investment in FRD sterilisation in India, where rabies is endemic, there is limited evidence of its impact on reducing FRD population sizes. Therefore, robust evaluation of the effectiveness of fertility control programmes is necessary. To address this, we implemented a Before After Control Intervention (BACI) framework in the first multi-site randomised controlled trial for the sterilisation of FRDs. We conducted single intensive sterilisation campaigns in five areas, achieving female sterilisation coverages of 58–66%. We observed a decrease in puppies and lactating females and a reduction in residents’ reports of barking, a common problem associated with FRDs. There were no significant differences in adult FRD counts between intervention and control sites during the 2-year follow-up. However, unmeasured immigration into and emigration out of study areas may have confounded counts. One-off, albeit intense, sterilisation campaigns in open populations require substantial investment and are unlikely to reduce population size in isolation, though there may be some reduction in problematic behaviours and improved animal welfare.README_ImpactsPaper.tx
An analysis of pre-service teachers’ reflections of ‘good practice’ teaching videos
No full textVideo clips of mathematics lessons are used extensively in initial teacher education and continuing professional learning activities. Given course time constraints, an opportunity to critique these videos is not always possible. Because of this, and because pre-service teachers make extensive use of material found during internet searches, much of it purporting to exemplify ‘good’ practice, we were interested to know what sense they make of such material. By encouraging pre-service teachers to reflect and comment on the practices being promoted in this way, we wanted to hear what they focused on, their initial views of the teaching and learning shown in the video, and how their views were formed and affected by engaging in discussion
Deconstructing ‘good practice’ teaching videos: An analysis of pre-service teachers’ reflections
Full text linkVideo clips of mathematics lessons are used extensively in pre-service teacher education and continuing professional development activities. Given course time constraints, an opportunity to critique these videos is not always possible. Because of this, and because pre-service teachers make extensive use of material found during internet searches, much of it purporting to exemplify ‘good’ practice, we were interested to know what sense they make of such material. By encouraging pre-service teachers to reflect and comment on the practices being promoted in this way, we wanted to hear what they focused on, their initial views of the teaching and learning shown in the video, and how their views were formed and affected by engaging in discussion. Findings indicate that pre-service teachers’ responses to the material were dominated by their beliefs about mathematics, and that engaging in discussion enabled them to appreciate the interpretations of others
Using grounded theory: a collaborative approach
No full textThere are many video clips that are widely available to support CPD for teachers but what do student teachers make of this material? This study focuses on student teachers following a one year post graduate initial teacher education programme. Student teachers were given a video clip to watch about supporting pupils make the transition from using the grid method to the standard written method. They split into small groups to discuss their initial thoughts and then came back together as a group (approximately 30 students) to share their thoughts more widely. Following this discussion they were asked to write a short reflection about the session. Seven researchers used grounded theory to analyse the data and this session will provide an overview of the approach we took. We will begin by showing the video clip used in the study and some excerpts from the student teachers’ reflections. We will explain the collaborative approach taken to coding the data and ask participants to engage in discussion about the codes we have assigned. Following this, early findings from the study will be discussed.<br/
On the multiphoton ionisation photoelectron spectra of phenol
No full textThe phenol molecule is a prototype for non-adiabatic dynamics and the excited-state photochemistry of biomolecules. In this article, we report a joint theoretical and experimental investigation on the resonance enhanced multiphoton ionisation photoelectron (REMPI) spectra of the two lowest ionisation bands of phenol. The focus is on the theoretical interpretation of the measured spectra using quantum dynamics simulations. These were performed by numerically solving the time-dependent Schrödinger equation using the multi-layer variant of the multiconfiguration time-dependent Hartree algorithm together with a vibronic coupling Hamiltonian model. The ionising laser pulse is modelled explicitly within the ionisation continuum model to simulate experimental femtosecond 1+1 REMPI photoelectron spectra. These measured spectra are sensitive to very short lived electronically excited states, providing a rigorous benchmark for our theoretical methods. The match between experiment and theory allows for an interpretation of the features of the spectra at different wavelengths and shows that there are features due to both ‘direct' and ‘indirect' ionisation, resulting from non-resonant and resonant excitation by the pump pulse
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
