Digital 3D models and measurements of avian brain cavity, blood vessel and nerve endocasts
No full textThis dataset comprises cast reconstructions of brain cavity space in 60 extant avian species, derived from X-ray micro computed-tomography scan image stacks. Each reconstruction was made using Materialise Mimics 14.11 to create volumetric models (brain cavity casts) that were then transformed into the polygon mesh stereolithograph (STL) files archived here. Brain cavity cast models are in most cases accompanied by casts of main vascular features (e.g., carotid arteries) and the olfactory nerves (CN I). A data file (Data_TableComma Separated Values) based on values reported in Table 1 of Walsh et al. (2013: doi:10.1371/journal.pone.0067176) is included that records volume values used in the original analysis, and coding of cerebellar flocculus morphology. Provenance & Quality: Data were collected from avian osteological specimens held in the collections of National Museums Scotland, Edinburgh, and the Natural History Museum, London. These data were derived from X-ray micro-CT scans conducted using Nikon Metrology HMX ST 225 scanners at the University of Abertay, Dundee and the Natural History museum at resolutions of 12-149 µm. Voxel segmentation of brain cavity casts was conducted using Materialise Mimics 14.11 by two team members and volume values collected from these segmentations

Gaming intensity – a pilot study of intensity of a sprint interval based cycle exergame
Get PDFCycle-based exergames deliver a moderate-intensity workload, but sprint interval exercise is a more effective training modality. This study aimed to examine the intensity of an in-house sprint-based game. Nine healthy participants completed an incremental time-to-exhaustion test to determine maximum heart rate and then played T Wrecks for 13 minutes, including 3 maximal sprint efforts (boss battle). Heart rate was recorded throughout. Peak heart rate significantly increased between boss battles (battle 1: 168 ± 13 BPM vs battle 2: 170 ± 15 BPM p=0.015, battle 1: 168 ± 13 BPM vs battle 3: 175 ± 12 BPM p<0.001, battle 2: 170 ± 15 BPM vs battle 3: 175 ± 12 BPM p<0.001). A significantly greater percentage of game time was spent in moderate to vigorous and vigorous intensities compared to moderate intensity (moderate to vigorous p=0.018; vigorous p=0.002) and in vigorous intensity compared to maximal intensity (vigorous p=0.018). The extent of the game demand (TRIMP 46.8 ± 8.8 A.U.) was dependent on game mechanics and not the fitness status of the participant (r=-0.13; p=0.747). This pilot study demonstrates that sprint-based cycle exergames can scale to fitness levels and effectively deliver sprint-based training, highlighting its potential to develop engaging, gamified exercise tools
Why we should reject to reject the use of generative Artificial Intelligence in qualitative analysis:a response to Jowsey, Braun, Clarke, Lupton, and Fine (2025)
Get PDFThis position paper argues against the categorical rejection of generative Artificial Intelligence (genAI) in qualitative analysis, as proposed by Jowsey et al. in their open-letter published in Qualitative Inquiry. While their concerns are framed as methodological, the authors’ position largely rest on philosophical assumptions that risk becoming dogma. In this short response I contend that prohibiting genAI on metaphysical grounds negatively impacts debate and innovation in qualitative analysis

The effect of hill sprints and battle ropes with supplementary vitamin D3 on repeated sprint ability in sub-elite combat sport athletes:a randomised double-blind prospective study
Get PDFObjectivesThe aim of this study is to evaluate if two weeks of concurrent hill sprint and battle rope training induces improvements in repeated sprint ability (RSA) and isometric strength in sub-elite combat sport athletes and if 50000IU·week-1 vitamin D3 supplementation produces an ergogenic benefit.MethodsFifteen male sub-elite combat sport athletes were recruited (age: 25 ± 4 years: stature: 176 ± 7cm: weight: 78 ± 18kg). Participants undertook baseline lower and upper body RSA testing, handgrip strength testing, isometric hold testing with red blood cell (RBC) lifespan also assessed. Participants were then assigned to consume 50000IU·week-1 vitamin D3 (VITD) or 5g·week-1 olive oil (CON). All participants completed three sessions per week for two weeks of hill sprint and battle rope training with testing repeated at post-intervention prior to statistical analysis with significance set at P<0.05.ResultsRBC lifespan decreased in CON (P<0.001) but not VITD (P=0.757). Lower and upper body peak power decrement decreased in CON (P=0.047 and P<0.001 respectively) with no significant improvement in other RSA markers of performance, handgrip strength or isometric hold ability. (P>0.05). In VITD, lower and upper body average power decrement decreased alongside an improvement in peak and average power held at the end of the RSA test (P<0.05) with lower body best peak power, handgrip strength and isometric hold ability improved (P<0.05).ConclusionTwo weeks of combined hill sprint and battling rope training improves lower and upper body RSA with 50000IU·week-1 of vitamin D3 providing an additive effect to improve RSA and muscle strength while also providing a protective benefit to RBCs.French title:Effets combinés des sprints en côte, de l'utilisation des battle ropes et d’une supplémentation en vitamine D3 sur l’aptitude à répéter des sprints chez des athlètes de sports de combat subélites : étude prospective randomisée en double ins
Post–visual diagnosis distress:the weight of threatened sight
Get PDFReceiving a diagnosis of a vision-threatening eye condition is a psychologically salient event for many patients. Across ophthalmology, fear, uncertainty, and emotional distress are commonly observed at the time of diagnosis, often before substantial functional vision loss occurs. Although depression and anxiety are well documented in chronic eye disease, diagnosis-linked distress remains inconsistently recognised and is rarely addressed systematically within routine ophthalmic care. This article introduces post-visual diagnosis distress (PVDD) as a descriptive, nondiagnostic framework to characterise the predictable, loss-related emotional responses that may arise following the diagnosis of a vision-threatening or irreversible eye condition. PVDD is not proposed as a psychiatric disorder, but as a clinically meaningful construct that helps legitimise patient experience, supports empathetic communication, and facilitates timely recognition and appropriate signposting when distress is significant. Drawing on evidence from age-related macular degeneration, glaucoma, and other chronic eye diseases, and informed by multidisciplinary perspectives spanning ophthalmology, psychiatry, counselling, patient advocacy, and public health, the article argues that recognising PVDD may improve patient engagement, quality of life, and psychological outcomes
Study data for thesis: An exploration of muscle oxygen kinetics in professional boxing
No full textData associated with the PhD thesis 'An Exploration of Muscle Oxygen Kinetics in Professional Boxing '. Study 1: In Study 1, the peripheral response of the rectus femoris muscle was investigated using NIRS wearable technology to determine the physiological demands of typical training modalities and a repeated sprint protocol in a sports science setting. 10 experienced professional boxers (age: 26±5 years, height: 177±4 cm, weight: 71±6 kg) on different days completed 6 x 3 minute rounds of pad, bag or spar-based training with 1 minute recovery time between each round, and on a separate occasion underwent lower body repeated Wingate trials, trials consisting of two, 30 second efforts against resistance (lower body 7.5%) with a 60 second active recovery. NIRS monitors where used to capture the physiological response, with data reported being time to both fast desaturation and fast resaturation and heart rate for all sessions. Study 2:Examined mitochondrial rate changes following a three-week self-directed sprint protocol in nine male professional boxers. Nine male professional boxers (age: 26±5 years, height: 177±4 cm, weight: 71±6 kg) participated in a pre-post study design. The protocol included an occlusion protocol to assess mitochondrial rate changes and an incremental treadmill test to volitional exhaustion. Data reported the linear slope(SmO2 percent per second) of each of the occlusions for all three sessions, along the rate constant(k). Study 3: This study Investigated the impact of heat on performance, recognising the common scenario where boxers transition from changing areas to competition areas with varying temperature conditions. Ten male professional boxers (age 27.22 ± 6.35, height, 175 ± 5.81 cm, weight 71.82 kg ± 5.12, body fat percentage 9.97 ± 2.72 kg) participated in a pre-post study design. The study consisted of participants undergoing repeated Wingate’s, 4 x 30 seconds with 60 second recovery, in both temperate conditions and hot conditions (35 degrees Celsius with 40 percent humidity), with data reported being sweat rates, haematocrit levels, time to both fast desaturation and fast resaturation, heart rate and wingate data such as peak, mean and average power
Female survivors of abduction in armed conflict zone: psychosocial needs, rehabilitation, and reintegration pathway
No full textThe data were collected to examine the involvement of female survivors of abduction from armed conflict zones in their rehabilitation and reintegration after their return. The aim of this research is to explore the perspective and experiences of returned women from abduction and captivity from armed conflict area in northeast Nigeria regarding the inclusion of their preferences. If their preferences are not included in their rehabilitation, explore a good practice strategy for supporting female survivors from armed conflict zones who have had their voice, freedom and choice taken away from them. The strategy is the creation of a rehabilitation and reintegration model using the women’s voice on how best to facilitate recovery and reintegration after abduction. This model can be used in any armed conflict zones. Currently, there is no pathway for the rehabilitation of returned women and very few studies in this area. This research is important because it does not only draw attention to the invisibility of returned women from captivity in armed conflict zones, it also proffered a rehabilitation pathway for the women. The participants for this study were recruited with the support of two non-governmental organisations (NGO), House of Hilkiah Foundation in Abuja and Hope And Rural Aid Foundation (HARAF) in. These NGOs were already supporting internally displace women (IDW), they had information on how the IDW were displaced and how they came to live in IDP camps. Study One investigated women's lived experiences regarding rehabilitation and reintegration after their return using Interpretative Phenomenological Analysis (IPA) through semi-structed interviews with ten returned women. Data was collected between February and August 2021 from returned women aged between 18 and 70 years living in internally displaced persons' (IDP) camps in Abuja and Yola. Abuja interviews were conducted physically while Yola interviews were virtual. Study Two explored how the status of the internally displaced persons' camps (designated or host community camps) affected the quality and frequency of support received using Thematic Analysis with semi-structured interviews of seven returned women aged between 18 and 55 years. Data were collected virtually between October and November 2022 from the FCT Abuja and Yola in northeast Nigeria. Study Three examined the violation of human rights due to issues like displacement, abduction, captivity, physical and sexual abuses, neglect and lack of choice using Qualitative Content Analysis of secondary data. The secondary data were some interviews from Studies One and Two where the violation of the women's rights were talked about by the women. The findings revealed that returned women were not involved in planning and implementing their rehabilitation. As a result, a step-by-step rehabilitation pathway incorporating the voices of returned women was developed to guide policy makers and professionals with input from returned women explaining how they should be rehabilitated
Effects of intermittent sprint-based heat acclimation at various pedal resistances on physiological responses during incremental exercise
Get PDFPurpose: Standard heat acclimation (HA) protocols (low-moderate intensity over a continuous 7-14 days) restore performance and thermoregulation but lack specificity and practicality for intermittent sports athletes. This study compared different pedal resistances in a 3-week intermittent sprint-based HA protocol.Methods: Fourteen physically active adults were assigned to a sprint pedal resistance training group (TG): 0.075 kg·kg⁻¹ (7.5TG, 6 males, 1 female) or 0.085 kg·kg⁻¹ (8.5TG, 5 males, 2 females). Participants completed baseline incremental time to exhaustion test (TTE), continued with own training for 3 weeks before post-control TTE, then carried out 6 X 15s cycle sprints with 30s recovery followed by 30min low intensity cycling thrice weekly for 3 weeks before completing post-HA TTE test. Testing and HA were completed at 38°C and 30% relative humidity.Results: Both groups improved TTE from baseline to post-HA (7.5TG: 9.6±10.8%, 8.5TG: 7.4±3.1%) and post-control to post-HA (7.5TG: 11.0±11.7%, 8.5TG: 6.7±3.9%). Maximal power improved from baseline to post-HA (7.5TG: 293±40 W vs 321±46 W, 8.5TG: 318±90 W vs 339±96 W), while only 7.5TG improved maximal power from post-control to post-HA (289±42 W vs 321±46 W) . From baseline to post-HA and post-control to post-HA, only 7.5TG increased time till maximum skin temperature (460±76 s vs 509±75 s, 461±72 s vs 509±75 s, respectively) and minimum core-skin gradient (461±71 s vs 510±74 s, 455±75 s vs 510±74 s, respectively), while exercising core temperature remained unchanged in both groups. Both groups increased sweat rate (7.5TG: 7.0±3.4 mgs·cm2·min-1 vs 9.6±4.1 mgs·cm2·min-1, 8.5TG: 5.7±3.6 mgs·cm2·min-1 vs 8.3±4.3 mgs·cm2·min-1) . Only 7.5TG delayed onset of blood lactate accumulation from baseline to post-HA (259±126 s vs 354±86 s) .Conclusion: Intermittent sprint-based HA improves TTE performance and sweat rate while a lighter sprint pedal resistance offers, greater thermal adaptation and fatigue tolerance
