Where do we grow from here? Assessing the perceived impact of a digital media commons on student success
Authors: Collins Armondo R. , Crowe Kathryn 
Published: October 2021

PurposeThe project was conducted to learn how the services of the digital media commons (DMC) impact and support student success. Data were collected to learn how faculty perceive the instructional support program, how patrons perceive the quality of the services and how students use the services, technology and the space that the DMC occupies. The results will be used to improve services and instruction and to inform the future direction of our instruction support service post-COVID-19.Design/methodology/approachThe project included three phases. First, a survey was sent to faculty who had brought their class for an instruction session to gain input on how they perceived the impact of the instruction and follow-up services on the quality of media projects. The second phase was a customer service survey implemented in the area to learn how patrons used the spaces and technology, what types of projects they completed in the DMC and their satisfaction with the assistance they received. The third phase employed student focus groups that followed up on the information from the survey to pinpoint how students perceive that the DMC impacts their academic success.FindingsThe data gained from the research indicated that (1) the teaching program provides important instruction for media projects, (2) the DMC provides important services and technology that contribute to student success and (3) The DMC space is an important destination for students as a learning space.Research limitations/implicationsThe scope of this case study is limited by the size of sample groups surveyed and the presumed veracity of their responses. The implications of our results do, however, align with reported trends experienced by peer institutions.Practical implicationsThis case study can be used by colleagues from other university's and learning environments to improve their space and instructional support offerings.Social implicationsDigital learning and work environments are increasing across the country due to society's demand for multimedia literacy instruction and technical support. This research will serve as a reference point for institutions starting and/or assessing the direct impact of digital spaces on student success and learning outcomes.Originality/valueAlthough there are many studies on the impact of academic libraries' services, space and resources on student success, few specifically address the contributions of academic library digital media services on student achievement. This project fills that gap and will serve as a model for future research.
Bank credit allocation and productivity: stylised facts for Portugal
Authors: Azevedo Nuno , Mateus Márcio , Pina Álvaro 
Published: October 2021

Purpose
The linkages between credit allocation and productivity have particular relevance in Portugal. This study aims to investigate whether credit extended by the Portuguese banking system has been allocated to the most productive firms within each sector.

Design/methodology/approach
With a data set covering 95% of total outstanding credit to non-financial corporations recorded in the Portuguese credit register, the authors investigate whether outstanding loans by resident banks to 64 economic sectors have been granted to the most productive firms. First, the authors estimate a baseline, reduced-form model of credit reallocation, where the parameter of interest gives the response of total credit granted to each firm to its level of productivity. Second, the authors assess how this response is affected by the share of credit allocated to unproductive firms. Third, the authors redo the analysis with credit granted to each firm by each banking group, instead of by the entire banking system, so that bank indicators can be taken on board.

Findings
The authors find evidence of misallocation, which reflects the joint effects of credit supply and credit demand decisions taken over the course of time, and the adverse cyclical developments following the accumulation of imbalances in the Portuguese economy for a protracted period. In 2008–2016, the share of outstanding credit granted to firms with very low productivity (measured or inferred) was always substantial, peaking at 44% in 2013, and declining afterwards with the rebound in economic activity and the growing allocation of new loans towards lower risk firms and away from higher risk firms. Furthermore, the authors find that misallocation is associated with slower reallocation. The responsiveness of credit growth to firm relative productivity is much lower in sectors with relatively more misallocated credit and when banks have a high share of such credit in their portfolios.

Originality/value
Banking system distortions are often mentioned as potential or likely culprits for capital misallocation, but they are not empirically analysed with credit data. The ability to explicitly analyse bank credit and link it to variables pertaining to both firms and banks is a novel feature relative to most previous studies, which largely rely on firm-level or sectoral data alone.

SummaryClostridium difficile isolates from the environment are closely related to those from humans, indicating a possible environmental transmission route for C. difficile infection (CDI). In this study, C. difficile was isolated from 47.3% (53/112) of lake/pond, 23.0% (14/61) of river, 20.0% (3/15) of estuary and 0.0% (0/89) of seawater samples. The most common toxigenic strain isolated was C. difficile PCR ribotype (RT) 014/020 (10.5%, 8/76). All water isolates were susceptible to fidaxomicin, metronidazole, rifaximin, amoxicillin/clavulanic acid, moxifloxacin and tetracycline. Resistance to vancomycin, clindamycin, erythromycin and meropenem was detected in 5.3% (4/76), 26.3% (20/76), 1.3% (1/76) and 6.6% (5/76) of isolates, respectively. High‐resolution core‐genome analysis was performed on RT 014/020 isolates of water origin and 26 clinical RT 014/020 isolates from the same year and geographical location. Notably, both human and water strains were intermixed across three sequence types (STs), 2, 13 and 49. Six closely related groups with ≤10 core‐genome single nucleotide polymorphisms were identified, five of which comprised human and water strains. Overall, 19.2% (5/26) of human strains shared a recent genomic relationship with one or more water strains. This study supports the growing hypothesis that environmental contamination by C. difficile plays a role in CDI transmission.
Mapping the evidence‐based practice research field in nursing from 1995 to 2021: A bibliometric analysis
Authors: Unal Aysun , Teskereci Gamze 
Published: October 2021

AbstractBackgroundEvidence‐based nursing and its practices are increasing rapidly in the health and nursing literature. A holistic image of evidence‐based nursing research is needed to address evidence‐based studies and available information on nursing.AimThe aim of this study was to evaluate evidence‐based nursing‐related research with bibliometric analysis in order to provide a structured macroscopic overview of its features and advances.MethodsA bibliometric analysis of 4,159 publications from 1995 to 2021 was performed to map the literature of evidence‐based nursing studies and assess the structure of the scientific community. The studies' publication output and growth trend, authors and collaborations, publishing journals, terms, current trends, subject categories, global distribution and collaboration, and the authors' average number of citations were all assessed.ResultsIt was found that the number of evidence‐based nursing publications increased until 2016, reaching the publication peak (n = 369), after which they began to decline. Most studies on the topic (n = 543) have been published in the journal Worldviews on Evidence‐Based Nursing. Evidence‐based knowledge, dissemination, implementation, implementation barriers, and implementation and training curricula in particular fields have all evolved over time as the key concepts of research. The United States (6,218), Australia (1,247), and England (790) are the three nations with the highest number of publications. On the other hand, it is seen that the subject has yet to be discussed in a few developing or underdeveloped countries.ConclusionsIn the last 12 years, evidence‐based nursing has been a comprehensive area of research. In comparison with the research areas in its field, it can be speculated that it has a more practical focus. It was determined that the authors' keywords primarily began with research implementation, practice development, and knowledge utilization over time, and then evolved to specific areas, educational areas, process applications, and important current topics such as Covid19.

AbstractAimThis study aimed to understand the lived experience of rural mothers caring for a child with a chronic health condition and to understand their perspectives on the support, services and resources they identify as necessary to effectively manage caregiving.BackgroundMaternal caregivers in rural areas experience difficulty accessing specialist health care for their child and can also experience geographical and social isolation. Understanding the factors that enable these maternal caregivers to overcome the challenges and adversities faced is crucial to help nurses identify and facilitate avenues for support and resources.DesignThis study employed a phenomenological design. The study is reported in line with Consolidated criteria for reporting qualitative research guidelines (COREQ).MethodsSemi‐structured interviews were conducted with 17 maternal caregivers in rural New South Wales, Australia, who had at least one child with a chronic health condition aged between 2–18 years. Data were collected from March to June 2018. Thematic analysis was used to develop a thematic framework. This paper reports on one of the major themes identified in this research, specifically maternal resilience.ResultsParticipants demonstrated maternal resilience by creating meaningful social connections, cultivating networks, developing problem‐solving skills, enhancing their self‐efficacy and finding a sense of purpose through hope and optimism. These strategies provide nurses insight into how some rural women overcome adversities associated with their maternal labour required in caring for a child with a chronic health condition.ConclusionThis study found that participants overcame the challenges related to their caregiving work, emerging as resilient caregivers. Understanding maternal resilience assists nurses to provide the services rural mothers in Australia need to care for their child with a CHC.Relevance to clinical practiceFindings from this study provide insight into the experiences of rural maternal caregivers of children with a chronic health condition and identify the strategies they adopt to overcome caregiver challenges. Understanding these strategies allows nurses to improve care and support for rural mothers using a strength‐based approach to build maternal resilience.

Abstract
It is well known that black and green tea extracts, particularly polyphenols, have antimicrobial activity against various pathogenic microbes including viruses. However, there is limited data on the antiviral activity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which emerged rapidly in China in late 2019 and which has been responsible for coronavirus disease 2019 (COVID-19) pandemic globally. In this study, 20 compounds and three extracts were obtained from black and green tea and found that three tea extracts showed significant antiviral activity against SARS-CoV-2, whereby the viral titre decreased about 5 logs TCID50 per ml by 1·375 mg ml−1 black tea extract and two-fold diluted tea bag infusion obtained from black tea when incubated at 25°C for 10 s. However, when concentrations of black and green tea extracts were equally adjusted to 344 µg ml−1, green tea extracts showed more antiviral activity against SARS-CoV-2. This simple and highly respected beverage may be a cheap and widely acceptable means to reduce SARS-CoV-2 viral burden in the mouth and upper gastrointestinal and respiratory tracts in developed as well as developing countries.

Published: October 2021

AbstractBackgroundPrevious studies show some patients with functional gastrointestinal disorders (disorders of gut‐brain interaction) may be at risk for or already have an eating disorder (ED). Avoidant/restrictive food intake disorder (ARFID) (ED not primarily motivated by body shape/weight concerns) may be particularly relevant but previous studies have been unable to fully apply diagnostic criteria. This study aimed to determine the frequency and nature of the full spectrum of ED symptoms, among adults with disorders of gut‐brain interaction.MethodsAdults with disorders of gut‐brain interaction (n = 99, 77.1% female, ages 18–82 years) from academic medical center gastroenterology clinics completed a modified ARFID Canadian Paediatric Surveillance Program Questionnaire, the ED Examination Questionnaire (EDE‐Q), and other self‐report measures of depression, generalized anxiety, and pain interference.Key ResultsOf the 93 participants who completed the measures, 37 (39.8%) had ARFID symptoms and 12 (12.9%) had clinically significant shape/weight‐motivated ED symptoms (EDE‐Q‐Global ≥4.0). Exploratory comparisons among ARFID, shape/weight‐motivated ED, and no‐ED groups revealed that ARFID symptom presence was associated with lower body mass index (BMI), and shape/weight‐motivated ED presence was associated with higher depression, anxiety, and pain interference. However, the majority (86%) of patients with ARFID symptoms had a BMI >18.5 kg/m2.Conclusions & InferencesThe full spectrum of ED symptoms was frequent among patients with disorders of gut‐brain interaction, particularly ARFID symptoms. Further research is needed to understand risk and maintenance factors to inform prevention and intervention efforts.
Antidepressant treatment trajectories and suicide attempt among Australians aged 45 years and older: A population study using individual prescription data
Authors: Carter Gregory , Sperandei Sandro , Chitty Kate M. , Page Andrew 
Published: October 2021

AbstractIntroductionMeta‐analyses show antidepressant initiation has increased risk of suicidal behavior <25 years, no difference 25–64 years and reduced risk 65+ years. Estimating risks from RCTs has limitations and real‐world population estimates are uncommon.MethodsA self‐controlled case series reporting incidence rate ratio (IRR) between exposed and control periods for antidepressants associated with suicide attempt, in Australian older age adults. We included all cases with suicide attempt [hospital data for ICD codes (X60–X84)] and any antidepressant use (n = 689) by participants in the “45 and Up Study”.ResultsFor all antidepressants the IRR for suicide attempt was elevated across all exposures, declining from 7.44 (95%CI 5.57–9.94) during the first 30 days, to 2.21 (1.73–2.81) at 91+ days. All four antidepressant sub‐groups had higher IRRs for the first 30 day exposure: 2.43 (1.37–4.29) for TCAs, 4.06 (2.78–5.93) for SSRIs, 4.15 (2.65–6.50) for other antidepressants, and 4.92 (3.30–7.34) for SNRIs. Increased IRR persisted for 61‐ to 90‐day exposures for SSRIs 2.42 (1.18–4.98) and SNRIs 2.66 (1.34–5.27).ConclusionSome older adults have increased risk of suicide attempt with antidepressant exposure, which may persist for months. Clinical guidelines should recommend a period of monitoring for treatment‐emergent suicidal thoughts and behaviors in older adult patients.
Geological record of a Cretaceous seismic event paired with multiple volcanic eruptions
Authors: Jeong Jong Ok , Jeon Yongmun , Sohn Young Kwan 
Published: October 2021

AbstractExplosive volcanic eruptions can occur within days to years after an earthquake, suggesting a causal relation between them. Such paired seismic–volcanic events in the past, which occurred on a human timescale, can only be confirmed by field relationship of eruptive products. The Southern Kusandong Tuff (SKT) is an ignimbrite in a Cretaceous backarc basin of Korea, which shows north‐to‐south variations in grain componentry, chemical composition, magnetic properties and palaeoflow patterns, suggesting that the tuff originated from two volcanic sources. Here we shows that the tuff resulted from two pyroclastic density currents (PDCs), which were generated by synchronous eruptions of two volcanoes in the nearby volcanic arc, most likely triggered by a regional seismic event, and then collided with each other in the backarc region within minutes. The paired seismic–volcanic event raises concerns for intensified volcanic hazards over large areas in regions of clustered volcanoes.
Increasing yield on dry fields: molecular pathways with growing potential

Published: October 2021

SUMMARYDrought stress constitutes one of the major constraints to agriculture all over the world, and its devastating effect is only expected to increase in the following years due to climate change. Concurrently, the increasing food demand in a steadily growing population requires a proportional increase in yield and crop production. In the past, research aimed to increase plant resilience to severe drought stress. However, this often resulted in stunted growth and reduced yield under favorable conditions or moderate drought. Nowadays, drought tolerance research aims to maintain plant growth and yield under drought conditions. Overall, recently deployed strategies to engineer drought tolerance in the lab can be classified into a ‘growth‐centered’ strategy, which focuses on keeping growth unaffected by the drought stress, and a ‘drought resilience without growth penalty’ strategy, in which the main aim is still to boost drought resilience, while limiting the side effects on plant growth. In this review, we put the scope on these two strategies and some molecular players that were successfully engineered to generate drought‐tolerant plants: abscisic acid, brassinosteroids, cytokinins, ethylene, ROS scavenging genes, strigolactones, and aquaporins. We discuss how these pathways participate in growth and stress response regulation under drought. Finally, we present an overview of the current insights and future perspectives in the development of new strategies to improve drought tolerance in the field.

Published: October 2021

AbstractThe production of activated carbons (ACs) from dirty plastic wastes derived from the mechanical/biological treatment of urban solid wastes, disposable plastics and plastics used in agriculture is reported. The use of these precursors is innovative and contributes to the circular economy by the valorization of dirty plastics that are usually disposed in landfills. ACs were produced by physical activation, with air or CO2, and chemical activation, with KOH or K2CO3. ACs presented a BET (N2) area and pore volume up to 723 m2/g and 0.32 cm3/g. Selected samples were tested for the 2,4‐dichlorophenoxyacetic acid (MCPA) and 4‐chloro‐2‐methyl‐phenoxyacetic acid (2,4‐D) removal from the liquid phase. PB‐K2CO3‐1:1–700 presented an apparent maximum adsorption capacity of 245 and 289 mg g−1 for MCPA and 2,4‐D, respectively.
Investigation on the Propulsion of a Pump-Jet Propulsor in an Effective Wake
Authors: Li Han , Huang Qiaogao , Pan Guang 
Published: October 2021

Abstract
The propulsion and vortical flow of a preswirl pump-jet propulsor (PJP) under effective wake conditions are numerically investigated by improved delayed detached eddy simulation. The numerical results agree well with the experiments. The effects of the interaction between the hull and PJP on the propulsion performance and flow characteristics are discussed in detail, particularly the effects on the flows around the duct and the stator. Results show that the PJP performance changes noticeably owing to the hull-retarded flow. The rotor forces are mainly changed due to the effective velocity magnitude of the PJP oncoming flow, while the flow direction does not show notable effects as the duct and stator notably improve the rotor oncoming flow. The appendage wake notably increases the thrust fluctuation of the rotor, causing dominant fluctuation components at low frequencies. The thrusts on the duct and stator are sensitive to the direction of the PJP oncoming flow, as the flows around them change considerably when the flow direction changes. The flow direction affects the velocity and pressure distribution of the duct and the generation and evolution of vortices in the stator region. The forward stagnation point on the duct plays a crucial role in duct thrust, around flow, and in the flow into the duct. The stator improves the uniformity of the rotor inflow during preswirling of the flow under effective wake conditions, which is very important for a submarine-applied PJP. The interaction between the hull and PJP is very complex.
