Event-based prospective remembering in a virtual world
Most laboratory-based prospective memory (PM) paradigms pose problems that are very different from those encountered in the real world. Several PM studies have reported conflicting results when comparing laboratory with naturalistic based studies (e.g., Bailey,Henry, Rendell, Phillips & Kliegel, 2010). One key contrast is that for the former, how and when the PM cue is encountered typically is determined by the experimenter, whereas in the latter case, cue availability is determined by participant actions. However, participant-driven access to the cue has not been examined in laboratory studies focused on healthy young
adults, and its relationship with planned intentions is poorly understood. Here we report a study of PM performance in a controlled, laboratory setting, but with participant-driven actions leading to the availability of the PM cue. This uses a novel PM methodology based upon analysis of participant movements as they attempted a series of errands in a large virtual building on the computer screen. A PM failure was identified as a situation in which a
participant entered and exited the “cue” area outside an errand related room without performing the required errand whilst still successfully remembering that errand post-test.
Additional individual difference measures assessed retrospective and working memory capacity, planning ability and PM. Multiple regression analysis showed that the independent measures of verbal working memory span, planning ability and PM were significant predictors of PM failure. Correlational analyses with measures of planning suggest that sticking with an original plan (good or bad) is related to better overall PM performance
MULTITASKING, WORKING MEMORY AND REMEMBERING INTENTIONS
Multitasking refers to the performance of a range of tasks that have to be completed within a limited time period. It differs from dual task paradigms in that tasks are performed not in parallel, but by interleaving, switching from one to the other. It differs also from task switching paradigms in that the time scale is very much longer, multiple different tasks are involved, and most tasks have a clear end point. Multitasking has been studied extensively with particular sets of experts such as in aviation and in the military, and impairments of multitasking performance have been studied in patients with frontal lobe lesions. Much less is known as to how multitasking is achieved in healthy adults who have not had specific training in the necessary skills. This paper will provide a brief review of research on everyday multitasking, and summarise the results of some recent experiments on simulated everyday tasks chosen to require advance and on-line planning, retrospective memory, prospective memory, and visual, spatial and verbal short-term memory
Computerisation and decision making in neonatal intensive care: a cognitive engineering investigation
This paper reports results from a cognitive engineering study that looked at the role of computerised monitoring in neonatal intensive care. A range of methodologies was used: interviews with neonatal staff, ward observations, and experimental techniques. The purpose was to investigate the sources of information used by clinicians when making decisions in the neonatal ICU. It was found that, although it was welcomed by staff, computerised monitoring played a secondary role in the clinicians' decision making (especially for junior and nursing staff) and that staff used the computer less often than indicated by self-reports. Factors that seemed to affect staff use of the computer were the lack (or shortage) of training on the system, the specific clinical conditions involved, and the availability of alternative sources of information. These findings have relevant repercussions for the design of computerised decision support in intensive care and suggest ways in which computerised monitoring can be enhanced, namely: by systematic staff training, by making available online certain types of clinical information, by adapting the user interface, and by developing intelligent algorithms
The role of self-care interventions on men’s health-seeking behaviours to advance their sexual and reproductive health and rights
Background: Self-care interventions are influencing people’s access to, expectation and understanding of healthcare beyond formal health delivery systems. In doing so, self-care interventions could potentially improve health-seeking behaviours. While many men proactively engage in maintaining and promoting their health, the focus on men’s health comes from the recognition, at least partially, that male socialization and social norms can induce men and boys to have a lower engagement in institutionalized public health entities and systems around their sexual and reproductive health and rights, that could impact negatively on themselves, their partners and children. Main text: A research agenda could consider the ways that public health messaging and information on self care practices for sexual and reproductive health and rights could be tailored to reflect men’s lived realities and experiences. Three examples of evidence-based self-care interventions related to sexual and reproductive health and rights that men can, and many do, engage in are briefly discussed: condom use, HIV self-testing and use of telemedicine and digital platforms for sexual health. We apply four core elements that contribute to health, including men’s health (people-centred approaches, quality health systems, a safe and supportive enabling environment, and behaviour-change communication) to each intervention where further research can inform normative guidance. Conclusion: Engaging men and boys and facilitating their participation in self care can be an important policy intervention to advance global sexual and reproductive health and rights goals. The longstanding model of men neglecting or even sabotaging their wellbeing needs to be replaced by healthier lifestyles, which requires understanding how factors related to social support, social norms, power, academic performance or employability conditions, among others, influence men’s engagement with health services and with their own self care practices
Changes in the capacity of visual working memory in 5- to 10-year-olds
Using the Luck and Vogel change detection paradigm, we sought to investigate the capacity of visual working memory in 5-, 7-, and 10-year-olds. We found that performance on the task improved significantly with age and also obtained evidence that the capacity of visual working memory approximately doubles between 5 and 10 years of age, where it reaches adult levels of approximately three to four items
The JNCC terrestrial biodiversity surveillance schemes: an assessment of coverage
Biodiversity information is needed to provide a sound evidence base for decision-making, including operational needs, statutory reporting requirements and strategic needs. In this study we sought to assess aspects of coverage so as to identify gaps in taxonomic, thematic (habitat) and spatial coverage which might need to be addressed in future
The Effects of Resistance Exercise Training on Quality of Life and Muscle Strength in Patients Undergoing Cancer Treatment: A Systematic Review
BACKGROUND: Breast cancer and prostate cancer are two of the most common cancers seen in females and males respectively worldwide. Treatments such as chemotherapy, radiation, and androgen deprivation therapy are essential to combat cancerous cells. However, the lasting side effects of these lifesaving treatments can impact an individual’s quality of life and muscle strength without appropriate intervention. While exercise has been shown to be beneficial for patients with cancer, there is limited understanding of the effects of resistance training when performed concurrently with medical interventions.
PURPOSE: The purpose of this systematic review was to evaluate the impact of resistance training on quality of life and muscle strength in patients with breast and prostate cancer undergoing cancer treatment.
METHODS: An academic search was conducted beginning August of 2020 and ending January 2021. The databases searched consisted of PubMed, EBSCO, Academic Search Ultimate, CINAHL, and Medline. This search yielded 18 randomized controlled trials, 11 pertaining to breast cancer and 7 pertaining to prostate cancer.
RESULTS: All articles utilized a myriad of outcome measures to see changes in QoL and muscle strength. Studies evaluated resulted in either a positive short term or no improvement during the period of active intervention. However, some studies did note a lack of long-term significant differences in outcome measures between the intervention and control groups. Review of the literature did not reveal patient attrition was due to adverse effects of the intervention.
CONCLUSION: Resistance training can be a safe and effective intervention to improve quality and life and muscle strength in patients undergoing cancer treatment. Current studies demonstrate the need for physical therapists to be included in the interdisciplinary approach from the moment of a cancer diagnosis.https://digitalcommons.misericordia.edu/research_posters2021/1044/thumbnail.jp
Increased prevalence of expiratory flow limitation during exercise in children with bronchopulmonary dysplasia.
Evidence regarding the prevalence of expiratory flow limitation (EFL) during exercise and the ventilatory response to exercise in children born preterm is limited. This study aimed to determine the prevalence of EFL as well as contributing factors to EFL and the ventilatory response to exercise in preterm children with and without bronchopulmonary dysplasia (BPD). Preterm children (=32 weeks gestational age) aged 9-12 years with (n=64) and without (n=42) BPD and term controls (n=43), performed an incremental treadmill exercise test with exercise tidal flow-volume loops. More preterm children with BPD (53%) had EFL compared with preterm children without BPD (26%) or term controls (28%) (p<0.05). The presence of EFL was independently associated with decreased forced expiratory volume in 1 s/forced vital capacity z-score and lower gestational age (p<0.05). There was no difference in peak oxygen uptake between preterm children with BPD and term controls (48.0 versus 48.4 mL·kg-1·min-1; p=0.063); however, children with BPD had a lower tidal volume at peak exercise (mean difference -27 mL·kg-1, 95% CI -49-?-5; p<0.05). Children born preterm without BPD had ventilatory responses to exercise similar to term controls. Expiratory flow limitation is more prevalent in children born preterm with BPD and is associated with airway obstruction and a lower gestational age
CARMENES input catalogue of M dwarfs IV. New rotation periods from photometric time series
Aims. The main goal of this work is to measure rotation periods of the M-type
dwarf stars being observed by the CARMENES exoplanet survey to help distinguish
radial-velocity signals produced by magnetic activity from those produced by
exoplanets. Rotation periods are also fundamental for a detailed study of the
relation between activity and rotation in late-type stars. Methods. We look for
significant periodic signals in 622 photometric time series of 337 bright,
nearby M dwarfs obtained by long-time baseline, automated surveys (MEarth,
ASAS, SuperWASP, NSVS, Catalina, ASAS-SN, K2, and HATNet) and for 20 stars
which we obtained with four 0.2-0.8 m telescopes at high geographical
latitudes. Results. We present 142 rotation periods (73 new) from 0.12 d to 133
d and ten long-term activity cycles (six new) from 3.0 a to 11.5 a. We compare
our determinations with those in the existing literature; we investigate the
distribution of P rot in the CARMENES input catalogue,the amplitude of
photometric variability, and their relation to vsin i and pEW(Halfa); and we
identify three very active stars with new rotation periods between 0.34 d and
23.6 d.Comment: 34 pages, 43 figures, 2 appendix table
