Pseudomyona from the Cambrian of North Greenland (Laurentia) and the early evolution of bivalved molluscs

logical studies of present day bivalves that the Ordo­ vician–Recent members of the Class Bivalvia Linnaeus, 1758 form a monophyletic group, although some relation­ ships within the group remain unresolved (Schneider 2001; Giribet 2008; Plazzi et al. 2011; Sharma et al. 2012, 2013; Bieler et al. 2014; González et al. 2015; Lemer et al. 2019). However, the derivation of Bivalvia from ancestral univalved molluscs and its stem group evolution in the Cambrian remains the subject of speculation (Cope 1997, 2000; Carter et al. 2000, 2011; Fang & Sánchez 2012; Cope & Kříž 2013; Ponder et al. 2020). Two Cambrian bivalved groups are recognised as potential ancestors of Bivalvia but their morphological dissimilarity, together with the general absence of material from the late Cambrian (Furongian), obscures the evolutionary pathway. The Order Fordillida Pojeta, 1975 includes Fordilla Barrande, 1881 (Fig. 1L, N) and Pojetaia Jell, 1980 (Fig. 1M) and its oldest members appeared in the Terreneuvian. The Order Tuarangiida MacKinnon, 1982 contains Tuarangia MacKinnon, 1982 (Fig. 1K) and is described from the late Miaolingian Series (Guzhangian Stage), about 20 Ma later. Tuarangia and the youngest specimens of Pojetaia occur together in the Guzhangian of Denmark (Hinz­Schallreuter 2000). Carter et al. (2011) rationalised the dilemma con­ cerning origin(s) by recognising two major divisions of Class Bivalvia. A Grade Euprotobranchia Nevesskaja, 2009 embraced the two orders Fordillida and Tuarangiida, which were considered in some way likely to be an­ cestral to crown group bivalves, but together did not comprise a monophyletic entity. The grade recognises the dichotomy as stem group bivalves between Fordilla and Pojetaia, and Pseudomyona Runnegar 1983 and Tuarangia, discussed by Runnegar & Pojeta (1992), as a result of which Pseudomyona and Tuarangia were not considered to be Bivalvia. Carter et al. (2006) had considered Tuarangia, Pseudomyona, Watsonella Grabau, 1900 (Fig. 1J) and Anabarella Vostokova, 1962 to form a sister group to Pojetaia and Fordilla and post­Cambrian Bivalvia. A Clade Eubivalvia Carter in Carter et al. (2011) included the post­Cambrian groups traditionally regarded as Bivalvia, but Sharma et al. (2013), Bieler et al. (2014) and others considered Fordilla to be a crown group bivalve. Conversely, Ponder et al. (2020, p. 552) placed
The Relationship of CSR Communication on Social Media with Consumer Purchase Intention and Brand Admiration

With the advent of the Internet and other digital technologies, contemporary businesses from all sectors are using social media for communication with consumers to engage them meaningfully with a brand. However, the use of social media for corporate social responsibility (CSR) communication is relatively new to the existing literature. Likewise, the impact of CSR communication through social media (CSR-S) on consumer emotions and behavior is, to date, underexplored. To address this, the present research aims to test the relationship of CSR-S on brand admiration and consumer purchase intention. The study proposes a direct relationship between CSR-S and purchase intention with a mediating effect of brand admiration. The data were collected from the banking consumers of Pakistan through a self-administered questionnaire. The authors distributed 800 questionnaires and received 463 questionnaires useful for data analysis, so the present research study response rate was around 59%. The data were analyzed using the structural equation modeling (SEM) technique in AMOS. The results revealed that CSR-S is positively related to purchase intention (β = 0.233). The results further showed that brand admiration partially mediates this relationship (β = 0.079). The survey respondents confirmed that their bank’s CSR communication helps enhance their purchase likelihood and their feelings of admiration for their bank. These findings will help policymakers at banking institutions better understand the importance of CSR communication on different social media platforms to achieve consumer-related outcomes.
Polysulfide‐Shuttle Control in Lithium‐Sulfur Batteries with a Chemically/Electrochemically Compatible NaSICON‐Type Solid Electrolyte

A NaSICON‐type Li+‐ion conductive membrane with a formula of Li1+ x Y x Zr2− x (PO4)3 (LYZP) (x = 0–0.15) has been explored as a solid‐electrolyte/separator to suppress polysulfide‐crossover in lithium‐sulfur (Li‐S) batteries. The LYZP membrane with a reasonable Li+‐ion conductivity shows both favorable chemical compatibility with the lithium polysulfide species and exhibits good electrochemical stability under the operating conditions of the Li‐S batteries. Through an integration of the LYZP solid electrolyte with the liquid electrolyte, the hybrid Li‐S batteries show greatly enhanced cyclability in contrast to the conventional Li‐S batteries with the porous polymer (e.g., Celgard) separator. At a rate of C/5, the hybrid Li ||LYZP|| Li2S6 batteries developed in this study (with a Li‐metal anode, a liquid/LYZP hybrid electrolyte, and a dissolved lithium polysulfide cathode) delivers an initial discharge capacity of ≈1000 mA h g−1 (based on the active sulfur material) and retains ≈90% of the initial capacity after 150 cycles with a low capacity fade‐rate of <0.07% per cycle.
Drones to the rescue? Exploring rescue workers' behavioral intention to adopt drones in mountain rescue missions

Purpose –Mountaineering and related activities are increasingly becoming popular and are accompanied by an increase in medical incidents. Emergency operations in mountainous terrain are time-critical and often pose major logistical challenges for rescuers. Drones are expected to improve the operational performance of mountain rescuers. However, they are not yet widely used in mountain rescue missions. This paper examines the determinants that drive the behavioral intention of mountain rescuers to adopt drones in rescue missions. Design/methodology/approach – This is a behavioral study that builds upon an extended model of the unified theory of acceptance and use of technology (UTAUT) and investigates the relationship between individual attitudes, perceptions, and intentions for drone adoption. Original survey data of 146 mountain rescuers were analyzed using moderated ordinary least squares (OLS) regression analysis. Findings – Results indicate that the behavioral intention to use drones in mountain rescue missions is driven by the expected performance gains and facilitating conditions. Favorable supporting conditions and experience with drones further moderate the relationship between performance expectancy and behavioral intention. The effects for effort expectancy, social influence, and demonstrations were not significant. Practical implications –Rescue organizations and stakeholders are recommended to consider the identified determinants in the implementation of drones in emergency logistics. Dronemanufacturers targetingmountain rescue organizations are advised to focus on operational performance, provide sufficient support and training, and promote the gathering of practical experience. Originality/value – A tailored-model that provides first empirical results on the relevance of personal and environmental factors for the acceptance of drones in emergency logistics is presented.
Effect of potassium sorbate dip-treatment in vacuum packaged Lethrinus lentjan fillets under refrigerated storage

The effect of vaccum packaging on the shelf life of refrigerated Lethrinus lentjan fillets was investigated. The fillets were diptreated with various concentrations (1.0%. 1.5% and 2.0%) of potassium sorbate, vacuum-packaged and stored in refrigeration temperature (4°C ± ± 1°C). The control and treated fillets were analysed periodically for biochemical (pH, TMA-N and TVB-N and FFA) and microbiological (TPC, psychrophiles, total anaerobes/facultative anaerobes, Lactobacillus and Staphylococcus counts), sensory (skin appearance, discoloration, gaping, texture and odour), quality characteristics. The shelf life periods of control packs were about 7-8 days, whereas the potassium sorbate treated fillets had an extended storage life of 20 days. Vacuum packaging alone could not prolong the shelf life of fillets in refrigeration temperature. Vacuum packaging in combination with potassium sorbate dip-treatment was found to delay the spoilage to a considerable extent by slowing down the microbial growth. Des filets de poisson (Lethrinus lentjan) ont ete trempes dans des solution de sorbate de potassium, emballes sous vide et refrigeres. Des analyses microbiologiques, biochimiques et sensorielles ont ete effectuees periodiquement sur un lot traite et un lot de controle. Les filets traites ont une duree de conservation de 20 jours alors que les filets non traites ne se conservent que 8 jours.
Controlled Release Of A poorly Water - Soluble Drug From An Amphiphilic And Ph - Sensitive Chitosan - Based Hydrogel

The present work focused on the design of drug delivery system based on an amphiphilic and pH-sensitive hydrogel. The hydrogels were prepared via graft copolymerization of acrylic acid (AA) onto chitosan backbones by a free radical polymerization technique. The structure and surface morphology of the hydrogels were characterized by FTIR and SEM, respectively. The swelling and pH-sensitive properties of the hydrogels were also investigated. Due to the reversible swelling behavior of the hydrogels, the synthesized networks can sense the environmental pH change and achieve an oscillatory release pattern. Using drug theophylline as a model molecule, loading and the in vitro controlled drug-release behaviors of these hydrogels were investigated. The loading yield was found to mainly depend on the crosslinker amount. The results also indicate that the main parameter affecting the drug-release behavior of hydrogels is the pH of the solution. The release rate of theophylline from hydrogel at pH 7.4 was faster than that at pH 1.2 due to the shrinkage of the hydrogel at pH 1.2.
Love and basketball: Audience response to a professional athlete’s mental health proclamation

Objective: On 6 March 2018, the Cleveland Cavaliers power forward Kevin Love penned an op-ed for The Players’ Tribune. In big, bold letters, the title, ‘Everyone Is Going Through Something’ gave way to his proclamation of personal mental health struggles. This study assessed the impact of Love’s personal mental health testimony on the audience. Design: Content analysis of Instagram user’s responses to Love’s 2018 announcement of panic disorder. Setting: Data were collected on 19 June 2018. Comments on Love’s post were manually copied into an Excel spreadsheet. Due to Instagram’s ‘top comments’ and ‘newest first’ algorithms that determine both the visibility and order of user responses, not all comments were accessible for analysis. A total of 1,234 comments served as the sample. Method: Two trained coders analysed the comments for exhibitions of audience involvement with Love, emotional responses and perceptions of social biases surrounding mental illness. Results: Social media users who expressed hope were more likely to share their own mental health experiences. In addition, users who expressed hope were significantly more likely to mention wanting to reduce social bias surrounding discussion of mental health than posts without hope. Conclusion: Building on previous work that determined social media users can respond to a celebrity’s physical health testimonial with positive, future-oriented emotions, this study established that the same response can exist when analysing a celebrity’s mental health testimonial.
Sediment mobilization by bottom trawls: a model approach applied to the Dutch North Sea beam trawl fishery

Bottom trawls impact the seafloor and benthic ecosystem. One of the direct physical impacts is the mobilization of sediment in the wake of trawl gear components that are in contact with or are close to the seabed. The quantity of sediment mobilized is related to the hydrodynamic drag of the gear components and the type of sediment over which they are trawled. Here we present a methodology to estimate the sediment mobilization from hydrodynamic drag. The hydrodynamic drag of individual gear components is estimated using empirical measurements of similarly shaped objects, including cylinders, cubes, and nets. The method is applied to beam trawls used in the Dutch North Sea flatfish fishery and validated using measurements of beam trawl drag from the literature. Netting contributes most to the hydrodynamic drag of pulse trawls, while the tickler chains and chain mat comprise most of the hydrodynamic drag of conventional beam trawls. Taking account of the silt content of the areas trawled and the number of different beam trawl types used by the fleet, sediment mobilization is estimated as 9.2 and 5.3 kg m−2 for conventional 12 m beam and pulse trawls, respectively, and 4.2 and 4.3 kg m−2 for conventional 4.5 m beam and pulse trawls.
Risk heterogeneity in compartmental HIV transmission models of ART as prevention in Sub-Saharan Africa: A scoping review.

BACKGROUND Transmission models provide complementary evidence to clinical trials about the potential population-level incidence reduction attributable to ART (ART prevention impact). Different modelling assumptions about risk heterogeneity may influence projected ART prevention impacts. We sought to review representations of risk heterogeneity in compartmental HIV transmission models applied to project ART prevention impacts in Sub-Saharan Africa. METHODS We systematically reviewed studies published before January 2020 that used non-linear compartmental models of sexual HIV transmission to simulate ART prevention impacts in Sub-Saharan Africa. We summarized data on model structure/assumptions (factors) related to risk and intervention heterogeneity, and explored multivariate ecological associations of ART prevention impacts with modelled factors. RESULTS Of 1384 search hits, 94 studies were included. 64 studies considered sexual activity stratification and 39 modelled at least one key population. 21 studies modelled faster/slower ART cascade transitions (HIV diagnosis, ART initiation, or cessation) by risk group, including 8 with faster and 4 with slower cascade transitions among key populations versus the wider population. In ecological analysis of 125 scenarios from 40 studies (subset without combination intervention), scenarios with risk heterogeneity that included turnover of higher risk groups were associated with smaller ART prevention benefits. Modelled differences in ART cascade across risk groups also influenced the projected ART benefits, including: ART prioritized to key populations was associated with larger ART prevention benefits. Of note, zero of these 125 scenarios considered lower ART coverage among key populations. CONCLUSION Among compartmental transmission models applied to project ART prevention impacts in Sub-Saharan Africa, representations of risk heterogeneity and projected impacts varied considerably. Inclusion/exclusion of risk heterogeneity with turnover, and intervention heterogeneity across risk groups could influence the projected impacts of ART scale-up. These findings highlight a need to capture risk heterogeneity with turnover and cascade heterogeneity when projecting ART prevention impacts.
Factor affecting the use of e-money in millennial generation: Research model UTAUT 2

This study aims to determine the factors that influence users in using electronic money in transactions. The Unified Theory of Acceptance and Use of Technology (UTAUT) is used as a research model with independent variables: performance expectations, facility conditions, social influence, expectations, perceived values, habits, beliefs, and hedonic motivation. The dependent variable in this study is actual use and interest to be used as a mediator variable. This research method uses an online survey method that is distributed using Google Surveys. This study's sample was 194 electronic money users spread across three major cities in Indonesia, such as DKI Jakarta, West Java, and Central Java. Primary data collected were analyzed using SmartPLS software. The study results explain that trust is a substantial factor in influencing the use of electronic money. Companies, in this case, must pay attention to system security factors to be able to attract millennials using electronic money.
Tests of hypotheses for group formation in the subtropical leaf‐dwelling bat, Kerivoula furva

Abstract Investigating factors that promote group living in animals can help us to understand the evolution of sociality. The dark woolly bat, Kerivoula furva, forms small groups and uses furled leaves of banana (Musa formosana) as day roosts in subtropical Taiwan. In this study, we reported on the roosting ecology and social organization of K. furva. We examined whether ecological constraints, demographic traits, and physiological demands contributed to its sociality. From July 2014 to May 2016, we investigated the daily roost occupation rate, group size, and composition of each roost, and we calculated association indices in pairs. The results showed K. furva lived in groups throughout the year, and the average daily roost occupation rate was approximately 6.7% of all furled leaves that were suitable for roosting. The size of roosting groups of adults in each roost varied between 1 and 13; group size was independent of air temperature during both reproductive and nonreproductive seasons. The vast majority of roosting groups was composed of females and their young, and males frequently roosted solitarily or in a bachelor group. Forty adult bats were captured ≥4 times during the study period. The association indices in pairs of these 40 bats ranged between 0 and 0.83 with an average of 0.05 ± 0.14 (n = 780). The average association index of female–female pairs was significantly higher than that of female–male pairs and male–male pairs. Based on the association indices, the 40 bats were divided into seven social groups with social group sizes that varied between 2 and 10. Despite changing day roosts frequently, the relatively stable social bonds were maintained year‐round. Our results that groups of K. furva were formed by active aggregation of multiple generation members supported the demographic traits hypothesis.
Factors Associated with the Occurrence of Skin Diseases among Children Attending the Children’s Outpatient Clinic in a Tertiary Care Hospital in Southern Nigeria

Aims: To determine the factors associated with the occurrence of skin diseases among children attending the Children’s Outpatient Clinic of the University of Port Harcourt Teaching Hospital (UPTH). Study Design: A Cross sectional study design was used. It was both descriptive and analytical. Place and Duration of Study: The study was carried out in the Children’s Outpatient Clinic of the Department of Paediatrics, UPTH from June to August 2020 (3 months). Methodology: We studied 370 children aged less than 18 years. A semi structured interviewer-administered questionnaire was used to obtain all relevant data. This was followed by dermatological examination of the children to make diagnosis of skin diseases. Relevant samples for laboratory confirmation were also obtained where necessary. Results: Among the 88 children (23.7%) who had skin diseases, our study showed that the socio-demographic factors associated with the occurrence of skin diseases includes: male gender (p=0.001) and low socio-economic class (p<0.001). Hygiene-related factors associated with occurrence of skin diseases includes: lack of water within the home (p=0.001), bath frequency < twice per day (p=0.001) and sharing of personal items (p<0.001). On multiple logistic regression analysis of these factors, the factors predictive of skin diseases were: male gender (p=0.000), low and middle socioeconomic class (p=0.004) and lack of water within the home (p=0.013). Conclusion: Several socio-demographic and hygiene-related factors were identified to be associated with the occurrence of skin diseases among children in our study. These factors provide an important window for interventions to prevent and control the burden of skin diseases among children in our setting.
Tourists’ Goal-Directed Behaviors: The Influences of Goal Disclosure, Goal Commitment, and Temporal Distance

Through the lenses of construal-level theory and goal-directed behavior theory, this study proposed and tested a conceptual model of tourists’ goal-directed behaviors. The proposed model depicted the impacts of tourism goal disclosure on tourists’ goal-directed behaviors through the mediation of goal commitment. The moderating role of temporal distance was also investigated. Two experimental studies were conducted to test hypotheses. Study 1 revealed that goal disclosure (vs. nondisclosure) on social media would enhance tourists’ commitment to tourism goals, which in turn would elicit more goal-directed behaviors. Study 2 further showed that the findings of study 1 are only applicable to the condition of short temporal distance. However, when it comes to the condition of long temporal distance, there is no significant difference in goal commitment and goal-directed behaviors regardless if the goal is disclosed or not. The findings of this study provided valuable theoretical and managerial implications.
Endoscopic balloon dilation for gastrojejunal anastomotic stricture after Roux‐en‐Y gastric bypass: A case series

Roux‐en‐Y gastric bypass (RYGB) is an effective bariatric procedure but is encountered with gastrojejunal (GJ) anastomotic stricture as a major complication. We aimed to evaluate the efficacy and complications of endoscopic balloon dilation in the management of GJ anastomotic stricture after RYGB. Patients who underwent balloon dilation for GJ anastomotic stricture secondary to RYGB between March 2009 and April 2013 in E‐Da hospital were reviewed retrospectively. A smaller balloon size (8 mm) was routinely chosen initially and the balloon size was increased gradually. Dilation was stopped if the patients felt abdominal pain or up to 15 mm in size. Thirteen patients (nine men and four women) with a median age of 26 years (range 20‐42 years) and a median body mass index of 41.5 kg/m2 (range 35.3‐65.4 kg/m2) were enrolled. Anastomotic size ranged from 1 to 4 mm. The median interval between surgery and the first dilation was 43 days (range 20‐112 days). Nine patients (69.2%) required only one dilation, three (23.1%) required two dilations, and one (7.7%) required three dilations. Seven patients (53.8%) had anastomotic ulcers. Two patients had perforation and were treated conservatively. Twelve patients (92.3%) were successfully treated by balloon dilation. One patient was found to have a total obstruction 4 months after the first dilation and underwent operation. This study suggests that endoscopic balloon dilation is effective in the management of GJ anastomotic stricture after RYGB and most of the patients responded to one dilation session. Although perforation occurred, it can be treated conservatively in our case series.
