Using fitness trackers to increase physical activity in a US Army health initiative

Objective: Fitness trackers are appealing in public health intervention programmes aimed at promoting physical activity, but it is unclear whether tracker use leads to health behaviour change in soldiers. This programme evaluation investigated the effects of fitness tracker usage on goal-setting, self-monitoring and physical activity behaviours in soldiers participating in a 6-month pilot health promotion programme focused on improving sleep, activity and nutrition behaviours. Design: Participants in this programme (n = 4,418) were assigned to a health education, an education plus fitness tracker or a comparison (i.e. no intervention) condition. Data were collected at baseline, 3 and 6 months. Setting: Soldiers in five brigades participated in one of the three conditions, with health education integrated into daily operations. Method: Participants in the health education and education plus fitness tracker conditions were exposed to materials distributed via health educators and through leader interaction. Participants in the education plus fitness tracker condition were also assigned a fitness tracker for use. Results: Self-monitoring increased in all conditions over time; however, there was a significant interaction of group by time, such that individuals in the fitness tracker condition reported significantly greater increases in self-monitoring over time, compared with the other groups. Conversely, self-reported physical activity decreased in all conditions over time, with no significant interaction, indicating no effect of group membership. Conclusion: Although fitness trackers are popular in the health and fitness industry, they may have limited utility as a public health intervention aimed at increasing physical activity in soldiers participating in this programme.
Secured Key Agreement Schemes in Wireless Body Area Network — A Review

Objective: To review different key agreement schemes which are used to establish Wireless body area network (WBAN) on the basis of identified attacks and also evaluate the schemes on performance parameters. Method: In this paper, an overview of WBAN, its architecture, difference between WSN and WBAN, IEEE 802.15. 6 specifications of WBAN, attacks in the environment and security essentials are discussed at first. It further divides the key agreement schemes into four classes and provides an extensive review of the schemes on the basis of distinct parameters viz. data confidentiality, node authentication, data integrity, mutual authentication, unforgeability, unlinkability, forward/backward secrecy, scalability, freshness, dos attack and node capture attack. Schemes are searched using the keywords- (“Traditional Key Agreement Scheme” OR “Physiological Key Agreement Scheme” OR “Signal Based Key Agreement Scheme” OR “Hybrid Key Agreement Scheme” OR “Security in Key Agreement Scheme”) AND (“Wireless Body Area Network” OR “WBAN” OR “Body Area Network” OR “BAN” OR “Body Sensor Network” OR “BSN” OR “Medical Body Area Network” OR “MBAN”). The papers are shortlisted around long stretches of 2003-2021 with a focus on recent work from IEEE Xplore, Springer, Science Direct, ACM, MDPI and Google Scholar databases. Schemes are analyzed against the mentioned attacks and the result of the comparative analysis is shown using tables and chart tools graphically. Findings: The wide coverage of the schemes in this review provides in-depth exposure to the shortcomings of the different schemes against the listed attacks which will provide a road map to the researchers to develop secure schemes in the future. Moreover, maximum schemes do not consider all the three aspects of performance viz. memory efficiency, computational efficiency and energy efficiency which are the foremost parameters in resource scarce environment of WBAN. Novelty: This review is unique as it analyzes the distinct key agreement schemes under specific attacks found in the literature while other review papers discuss the general aspects of the security threats and corresponding counter measures in WBAN environment. It also provides the performance analysis of the key management schemes which are missing from other review works. Keywords: WBAN; IOT; Bio sensors; Security; Privacy; Attacks; Encryption; Key agreement schemes; IEEE 802.15. 6

How chatbots' social presence communication enhances consumer engagement: the mediating role of parasocial interaction and dialogue

PurposeThis study presents one of the earliest empirical investigations on how brand chatbots' anthropomorphic design and social presence communication strategies may improve consumer evaluation outcomes via the mediators of parasocial interaction and perceived dialogue.Design/methodology/approachThis study employs a 2 (high vs. low social presence communication) by 2 (anthropomorphic vs. non-anthropomorphic bot profile) between-subject experimental design to evaluate how chatbots' high social presence communication and anthropomorphic profile design may enhance perceptions of parasocial interactions and dialogue with the chatbot, which in turn drive user engagement, interaction satisfaction and attitude toward the represented brand.FindingsThe influences of chatbots' high social presence communication on consumer engagement outcomes are mediated by perceived parasocial interaction and dialogue. Additionally, chatbots' anthropomorphic profile design can boost the positive effects of social presence communication via the psychological mediators.Originality/valueThis study advances the interactive marketing literature by focusing on an emerging interactive technology, chatbots. Additionally, distinct from prior chatbot studies that focused on the utilitarian use of chatbots for online customer support, this study not only examines which factors of chatbot communication and profile design may drive chatbot effectiveness but also examines the mechanism underlying the messaging and design effects on consumer engagement. The findings highlight the mediating role of interpersonal factors of parasocial interaction and perceived dialogue.
Artillery structural dynamic responses optimization based on Stackelberg game method

This article proposes an artillery structural dynamic response optimization method based on the Stackelberg game theory. The artillery multi-flexible body dynamic model is constructed firstly, and the live firing experiment is carried out to verify the accuracy of the constructed model. The multi-objective optimization model of artillery structural dynamic responses is established, and the sensitivity analysis and fuzzy c-means cluster algorithm are used to split the design variable set and, more importantly, transform the optimization model into a two-leader-one-follower Stackelberg game model. The process of solving Stackelberg equilibrium is a bi-level optimization, where the two leaders play a Nash sub-game first and impose the decision to the follower and then the follower makes its own optimization with considering this decision. Until the leaders cannot obtain more profits, the Stackelberg equilibrium is reached. The results demonstrate that the artillery structural dynamic responses have been greatly improved.
Burden of multiple myeloma in China: an analysis of the Global Burden of Disease, Injuries, and Risk Factors Study 2019

Abstract Background: There is limited data to comprehensively evaluate the epidemiological characteristics of multiple myeloma (MM) in China; therefore, this study determined the characteristics of the disease burden of MM at national and provincial levels in China. Methods: The burden of MM, including incidence, mortality, prevalence, and disability-adjusted life years (DALYs), with a 95% uncertainty interval (UI), was determined in China following the general analytical strategy used in the Global Burden of Disease, Injuries, and Risk Factors Study 2019. The trends in the burden of MM from 1990 to 2019 were also evaluated. Results: There were an estimated 347.45 thousand DALYs with an age-standardized DALY rate of 17.05 (95% UI, 12.31–20.77) per 100,000 in 2019. The estimated number of incident case and deaths of MM were 18,793 and 13,421, with age-standardized incidence and mortality rates of 0.93 (95% UI, 0.67–1.15) and 0.67 (95% UI, 0.50–0.82) per 100,000, respectively. The age-specific DALY rates per 100,000 increased to more than 10.00 in the 40 to 44 years age group reaching a peak (93.82) in the 70 to 74 years age group. Males had a higher burden than females, with approximately 1.5- to 2.0-fold sex difference in age-specific DALY rates in all age groups. From 1990 to 2019, the DALYs of MM increased 134%, from 148,479 in 1990 to 347,453 in 2019. Conclusion: The burden of MM has doubled over the last three decades, which highlights the need to establish effective disease prevention and control strategies at both the national and provincial levels.
Microbiological quality aspects of ready-to-eat foods with focus on antibiotic resistance and biofilm formation abilities of foodborne bacteria

In this study, microbiological quality of 93 ready-to-eat food products was determined by enumeration of total aerobic bacteria and members of Enterobacteriaceae. Presence of Staphylococcus aureus and Listeria monocytogenes in the products were also investigated. Aerobic colony counts were between 1.9 × 102–3.4 × 108 CFU g−1 for 84.9% and Enterobacteriaceae counts were between 2 × 102 and 6.7 × 106 CFU g−1 for 43% of the samples. S. aureus was detected in 7.5% of the samples, but L. monocytogenes was not detected in any sample. 72.9% of the Enterobacteriaceae isolates showed resistance to at least one antibiotic tested, and 5 among the S. aureus isolates were found to be resistant to penicillin G and 2 against methicillin. Four S. aureus isolates produced only Staphylococcal enterotoxin A and 1 isolate produced both Staphylococcal enterotoxin A and B. Biofilm experiments revealed biofilm formation on polystyrene for 95.8%, 87.5%, and 91.6% of Enterobacteriaceae isolates at 4 °C, 22 °C, and 37 °C, respectively, whereas all S. aureus isolates formed biofilm at all temperatures.
Informal community spaces, mentoring and representation: unpacking factors that influence African American engineering undergraduates

PurposeIn this article, we examine the experiences of African American engineering undergraduate students who participated in two student–faculty mentoring programs. This work provides critical insights about important factors that enhance students' experiences in higher education (e.g. the need for informal community spaces, mentoring and representation). Design/methodology/approachUsing a sequential explanatory mixed-methods approach, participants were surveyed and interviewed about their experiences in the mentoring programs. Data were analyzed using basic statistical methods and thematic analysis.FindingsFindings indicate that students prosper in informal community spaces, where representation allows them to build mentoring relationships that are fostered naturally through common identities in a shared space.Research limitations/implicationsGiven the intimate size of the program, the sample population was limited.Practical implicationsTo benefit student development, mentoring program practices should consider dedicating funding and space for students and faculty of shared racial backgrounds and lived experiences to meet informally.Originality/valueThis work identifies explicit mentoring program factors that support the development of minoritized students in engineering.
Unilateral Spatial Neglect Due to Stroke

ABSTRACT Unilateral spatial neglect refers to a condition where patients do not react to various environmental stimuli originating from the contralateral side of a brain lesion, in the absence of other sensory or motor deficits. Consequently, activities of daily living can be adversely affected. Cerebral hemorrhage or infarction is often the cause, and approximately 80% of patients with right hemisphere injury from acute stroke show unilateral spatial neglect. The presence of unilateral spatial neglect is determined through a number of different tests. However, even cases that are not apparent from typical tests are often associated with symptoms of neglect in activities of daily living. Stroke-mediated unilateral spatial neglect may improve or disappear during rehabilitation; however, in most cases, it remains. Cerebral hemorrhage, bleeding site, level of hematoma, and age are closely related with prognosis. Treatment approaches include conscious behavioral changes and activation of higher-order central nerves by stimulation from the periphery. Several mechanisms have been proposed to explain the onset of unilateral spatial neglect. Therefore, treatment strategies should be formulated only after careful examination and determination of the causative mechanism specific to each patient. This will enable the rehabilitation team to provide the most appropriate support.
Perspectives of Indonesian parents towards school-based sexuality education

ABSTRACT Internationally, school-based sexuality education programmes have shown to improve sexual practices and health outcomes for young people. However, perceived parental discord is commonly cited as a barrier to implementation. Within Indonesia, there is limited empirical evidence regarding parents’ attitudes towards school-based sexuality education. A sample of 768 Indonesian parents and caregivers completed an online Qualtrics survey to determine their level of support or disapproval towards the provision of sexuality education within primary and secondary schools. The majority of parents supported school-based sexuality education (n = 756, 98.4%) and suggested certain topics should commence as early as kindergarten and elementary school (n = 615, 80.0%). Religious affiliation was not associated with permissiveness. When presented with a range of sexuality topics, most parents agreed their inclusion was important. However, for some topics, there was significant variability in opinion based upon the age, gender, or educational background of the parent; thereby providing opportunity for further work. This preliminary study challenges notions that parents, particularly those with religious affiliations, are barriers to the delivery of sexuality education within Indonesia schools. Further research and advocacy will hopefully encourage educators to expand their current levels of provision, to align with international and evidence-based guidelines.
Impact of inclusion of hybrid red tilapia (Oreochromis mossambicus × O. niloticus), on total production in farm pond aquaculture

The present study was conducted to evaluate the impact of inclusion of hybrid red tilapia ( Oreochromis mossambicus × O. niloticus ) on productivity in carp based pond aquaculture. An experiment for a period of 270 days was conducted in two sets of earthen ponds (each of 0.132 ha size with 1.5 m depth). In Set I, five species viz. Catla catla , Labeo rohita , Cirrhinus mrigala, Ctenopharyngodon idella and Cyprinus carpio ) were stocked (@13636 ha -1 ) in a respective ratio of 1:1:1:1:2. In Set II, hybrid red tilapia was included as additional species to other five carp species and stocked @ 13636 ha -1 in equal numbers. The seeds stocked (initial size 5-6 cm) were fed on commercial pellet feed having 20% protein, by broadcasting over the pond surface. The water quality parameters viz . , temperature, pH, dissolved oxygen, alkalinity, nitrogen, phosphate and potassium remained more or less same in both the sets of experimental ponds. However fish growth parameters significantly differed in both the sets of experiments. Highest production of 2575.79±107.08 kg ha -1 was recorded in Set II followed by Set I with a production of 1894.32±428.44 kg ha -1 . Tilapia stocked as an additional species provided a net estimated additional yield of 680.64 kg ha -1 , which was 36.47% higher than that of Set I. The results of this study have proved significant impact of hybrid red tilapia inclusion on enhancing the net productivity.
The interaction between lysyl-lysine and arginine in the neonatal Yucatan miniature pig small intestine

Using an in situ intestinal perfusion model in sow-fed neonatal piglets, our objectives were to determine whether the lysyl-lysine enhanced arginine absorption led to a functional benefit of greater mucosal protein synthesis, and whether it was mediated through the mTOR pathway. Three segments of piglet’s small intestine were isolated, and were continuously perfused with: arginine, arginine + lysyl-lysine, or arginine + L-lysine. At 90 min, buffers containing the same amino acids plus phenylalanine were initiated for 30 min to measure mucosal protein synthesis. Six additional piglets underwent the identical protocol, but one hour before the intestinal perfusion, rapamycin was delivered intravenously. Co-perfusing arginine with lysyl-lysine resulted in greater arginine uptake, and higher mucosal protein synthesis. Moreover, both protein synthesis and the phosphorylation of mTOR were inhibited by rapamycin. Thus, lysyl-lysine led to a greater mucosal protein synthesis, which was likely mediated through enhanced arginine absorption.
Special Functions as Solutions to the Euler–Poisson–Darboux Equation with a Fractional Power of the Bessel Operator

In this paper, we consider fractional ordinary differential equations and the fractional Euler–Poisson–Darboux equation with fractional derivatives in the form of a power of the Bessel differential operator. Using the technique of the Meijer integral transform and its modification, fundamental solutions to these equations are derived in terms of the Fox–Wright function, the Fox H-function, and their particular cases. We also provide some explicit formulas for the solutions to the corresponding initial-value problems in terms of the generalized convolutions introduced in this paper.
Annotating and prioritizing genomic variants using the Ensembl Variant Effect Predictor—A tutorial

The Ensembl Variant Effect Predictor (VEP) is a freely available, open‐source tool for the annotation and filtering of genomic variants. It predicts variant molecular consequences using the Ensembl/GENCODE or RefSeq gene sets. It also reports phenotype associations from databases such as ClinVar, allele frequencies from studies including gnomAD, and predictions of deleteriousness from tools such as Sorting Intolerant From Tolerant and Combined Annotation Dependent Depletion. Ensembl VEP includes filtering options to customize variant prioritization. It is well supported and updated roughly quarterly to incorporate the latest gene, variant, and phenotype association information. Ensembl VEP analysis can be performed using a highly configurable, extensible command‐line tool, a Representational State Transfer application programming interface, and a user‐friendly web interface. These access methods are designed to suit different levels of bioinformatics experience and meet different needs in terms of data size, visualization, and flexibility. In this tutorial, we will describe performing variant annotation using the Ensembl VEP web tool, which enables sophisticated analysis through a simple interface.
Impact of beaver dam analogues on hydrology in a semi‐arid floodplain

Natural beaver ponds help connect the stream to the floodplain, maintain late summer low flows and reduce peak flow during high flow events by offering temporary surface water (SW) storage. When beavers are extirpated from the landscape, stream degradation often ensues. This study assesses the impact of beaver dam analogues (BDA) as a stream restoration technique to help maintain low flow water levels and enhance stream‐floodplain interactions on a seasonal basis in Red Canyon Creek, Lander, WY. BDAs increased SW and groundwater (GW) levels, favoured the occurrence of flow reversals (i.e., stream‐to‐floodplain GW flow) during high flow events associated with mid‐winter and early‐spring thaw events, and reduced the groundwater‐to‐stream hydraulic gradient on an annual basis. Although GW temperatures varied seasonally, relatively cooler GW temperatures were observed in the BDA impacted reach compared to the control reach away from BDA influence. BDAs however did not significantly impact stream temperatures. Overall, results suggest that when installed in sequence, BDA complexes can successfully reconnect the stream to its floodplain, and ultimately increase SW‐GW exchange at the floodplain scale by allowing flow reversals to occur and by reducing the GW to stream hydraulic gradient. Although BDAs built with fence posts, willow branches, sediments and small boulders are naturally porous and require regular maintenance, this study also highlights the viability of small BDAs as a restoration practice to enhance landscape resilience to drought and high flow events in deeply incised channels where beavers would not come back naturally.
