Direct evidence of a prey depletion “halo” surrounding a pelagic predator colony

Colonially breeding birds and mammals form some of the largest gatherings of apex predators in the natural world and have provided model systems for studying mechanisms of population regulation in animals. According to one influential hypothesis, intense competition for food among large numbers of spatially constrained foragers should result in a zone of prey depletion surrounding such colonies, ultimately limiting their size. However, while indirect and theoretical support for this phenomenon, known as “Ashmole’s halo,” has steadily accumulated, direct evidence remains exceptionally scarce. Using a combination of vessel-based surveys and Global Positioning System tracking, we show that pelagic seabirds breeding at the tropical island that first inspired Ashmole’s hypothesis do indeed deplete their primary prey species (flying fish; Exocoetidae spp.) over a considerable area, with reduced prey density detectable >150 km from the colony. The observed prey gradient was mirrored by an opposing trend in seabird foraging effort, could not be explained by confounding environmental variability, and can be approximated using a mechanistic consumption–dispersion model, incorporating realistic rates of seabird predation and random prey dispersal. Our results provide a rare view of the resource footprint of a pelagic seabird colony and reveal how aggregations of these central-place foraging, marine top predators profoundly influence the oceans that surround them.

Human Factors and Requirements of People with Cognitive Impairment, Their Caregivers, and Healthcare Professionals for mHealth Apps Including Reminders, Games, and Geolocation Tracking: A Survey-Questionnaire Study

Background: Mobile Health (mHealth) apps can delay the cognitive decline of people with dementia (PwD), by providing both objective assessment and cognitive enhancement. Objective: This patient involvement survey aims to explore human factors, needs and requirements of PwD, their caregivers, and Healthcare Professionals (HCPs) with respect to supportive and interactive mHealth apps, such as brain games, medication reminders, and geolocation trackers through a constructive questionnaire. Methods: Following the principles of user-centered design to involve end-users in design we constructed a questionnaire, containing both open-ended and closed-ended questions as well as multiple choice and Likert scale, in order to investigate the specific requirements and preferences for mHealth apps. We recruited 48 participants including people with cognitive impairment (n = 15), caregivers (n = 16), and HCPs (n = 17) and administered the questionnaire. Results: All participants are likely to use mHealth apps, with the primary desired features being the improvement of memory and cognition, assistance on medication treatment, and perceived ease to use. HCPs, caregivers, and PwD consider brain games as an important technology-based, non-pharmaceutical intervention. Both caregivers and patients are willing to use a medication reminder app frequently. Finally, caregivers are worried about the patient wandering. Therefore, global positioning system tracking would be particularly important to them. On the other hand, patients are concerned about their privacy, but are still willing to use a geolocation app for cases of emergency. Conclusion: This research contributes to mHealth app design and potential adoption. All three groups agree that mHealth services could facilitate care and ameliorate behavioral and cognitive disturbances of patients.

Sharing economy services in Dhaka: a change towards women’s perception of commuting

Purpose In the modern era of transportation, using a ride-sharing service can add an extra value to the lifestyles of women. Also, women are thinking about the ride-sharing service, what are the factors they consider while purchasing the service and so on. The purpose of this study is to find out women’s perception of ride-sharing services. Design/methodology/approach This paper is based on deductive research approach and descriptive research design. This paper has followed mixed research method by using qualitative and quantitative data. By dividing the larger population into subgroups, the researchers have conducted a survey on 240 respondents. To select these respondents, researchers have applied simple random technique. Based on a survey on consumers’ buying behaviour of ride-sharing service, the researchers tested the impact of tangibility, reliability, safety, fare, efficiency and convenience as the factors for choosing ride-share rather than other public transportation. Findings The study results indicate that reliability which includes consistency, punctuality and schedule routes are the major concerning issue for women while choosing ride-share service. Women are also concerned about efficiency which includes global positioning system tracking, smartphone technology and so on. One of the important criteria for choosing a ride-sharing service is safety, which includes verified drivers, and drivers review scores. So, reliability, efficiency and safety are the most effective issues. On the other hand, tangibility, fare and convenience do not affect that much. Originality/value To the best of the authors’ knowledge, this is the first research to scrutinize the sharing economy service in Dhaka city towards women’s perception of commuting.

Does competition standard and player position influence the match-play physical demands of Australian elite youth male soccer players within a single squad?

The purpose of this study was to investigate the influence of competition standard and player position on the physical demands of Australian elite youth male soccer players during match-play. Twenty-three elite youth male soccer players from the same Australian U17 National Centre of Excellence program were observed across 8 National Youth League (NYL) and 21 National Premier League (NPL) competition matches. Total (TD/min), low- (< 3.6 m/s), moderate- (3.6–5.0m/s) and high-speed (> 5.0 m/s) running distance, and the accelerations (Acc/min) (≥ 2.0 m/s2) and decelerations (Dec/min) (≤ −2.0 m/s2) were recorded using 15-Hz portable global positioning system tracking devices (GPSports, Canberra, Australia). An interaction was observed between competition standard and player position for TD/min ( p = 0.003), HSRD/min ( p = 0.007) and Acc/min ( p = 0.037) indicating the influence that competition standard had on these variables varied according to player position. Furthermore, we report that Central Defenders (3.1%), External Attackers (4.2%) and Central Attackers (3.8%) performed more TD/min in NYL (professional development level) compared to NPL (semi-professional) match-play. Central Defenders (24.2%) and Central Attackers (17.0%) completed more HSRD/min in NYL (professional development level) compared to NPL (semi-professional) match-play. Central Defenders (47.8%), External Defenders (20.5%), Midfielders (18.5%) and External Attackers (32.3%) all performed more Acc/min in NPL (semi-professional) when compared to NYL (professional development level) match-play. The results of this study provide scientific basis to aid the match-preparation of Australian elite youth male soccer player’s transition to higher standards of soccer.

Pediatric Tuberculosis and a Unique Method of Case Finding and Default Prevention: The Case of Baby ‘Lucky’, Moyale Sub-County, Kenya, 2019

Use of innovative global positioning system tracking of pregnant pastoralist women allowed staff to find the mother, locate the infant and enroll the infant in care and treatment. Due to this innovative intervention of case finding and tracking, the infant was prevented from defaulting and completed his anti-TB regimen.

A Framework for Real-time Cattle Monitoring using Multimedia Networks

Monitoring cattle behaviour has been a perpetual challenge in animal husbandry and animal breeding. Various methods have been used in the past to monitor the behaviour of cattle and their grazing patterns. We proposed a framework for real time cattle monitoring using multimedia networks. The study observes the grazing patterns of cattle and their behaviours in the grazing field. In order to accomplish the above observation, global positioning system monitoring collar for cattle is utilized; this technology monitors the activities of individual cattle during grazing through a networked system. The materials used in carrying out the work include cattle, waterproof global positioning system tracking collars (TR20) for cattle, and supporting application software by Sigfox’s global Internet of Things network. The paddock size was 121 by 174 m. Forage was predominantly agricultural plants. Cattle weighing up to 580 kg were used. The collared cattle were used to initiate all data collections. Latitude and longitude information of location was cumulatively stored in memory that is on-boarded and big enough for the fixing of position. Each fix record is comprised of corresponding estimation of height, date and time of global positioning system, precision value dilution, status of fix, temperature, including horizontal and vertical activity sensor counts in intervals that are fixed. Units of collar were well compacted, robust, and of about 1 kg in weight. Location fixes for over a day period were showed through testing to be accurate, at roughly 95% for eight minutes of time after correction of the difference. There was no bias of direction on the part of errors that have consistency with other studies’ finding.
