Authors: Combrinck Yvonne , Van Wyk Neltjie C. , Mogale Ramadimetja S. 
Published: July 2021

AbstractAimThis study aimed to develop and refine strategies for preserving nurses’ professional dignity.BackgroundProfessional dignity is a non‐negotiable nursing professional value. It should at all times be respected because of the worthiness of nurses as professional human beings. They are at the centre of healthcare societies. Their worth and contributions to the health of others should be acknowledged and preserved.MethodsDescriptive qualitative research was conducted during the development of the strategies while applying the principles of strategic navigation. The process was guided by the findings of the initial phase of the study and contextualised literature. Focus group discussions were held with healthcare professionals for the refinement of the strategies in two private hospitals in South Africa.FindingsThe strategies unfolded multiple possibilities to value nurses’ professional dignity. These were pathways for respecting, appreciating and supporting nurses; honouring nurses’ desire to hold the well‐being of patients in the highest regard; supporting nurses in fulfilling their professional roles; enabling nurses to take pride in themselves and the nursing profession; supporting nurses in demanding and complex circumstances and supporting nurses in coping with humiliating workplace experiences.ConclusionStrategies to ensure successful outcomes in preserving nurses’ professional dignity were developed and refined. The professional dignity experiences that mattered most were presented.Implications for nursing/health policyValuing nurses’ professional dignity promotes respect and support for nurses and their desire to prioritise patient‐centred care, contributing to improved nursing practice and nurses’ confidence to assert their professional dignity. Preserving nurses’ professional dignity is a necessity in healthcare. It should be affirmed in equal standing in nursing codes of conduct, nursing curriculums and healthcare policies.
From ambidextrous learning to digital creativity: An integrative theoretical framework
Authors: Shao Zhen , Li Xixi , Wang Qian 
Published: July 2021

AbstractDigital creativity (DC) stands for employee's generation of useful and fresh ideas through the use of digital technologies, which is one of the prominent consequences of effective digital technology use. Drawing insights from the tripartite view of technology use (ie, technology, individual and task elements) and the social role lens, our study proposes and tests an integrative theoretical framework to understand how female and male employees progress from ambidextrous learning in digital technology use to DC. We first interviewed five frontline employees and then surveyed 221 employees that were different from the interview sample from eight organisations. All participants utilised a similar version of internet‐of‐things (IoT) in their daily work. We find that (a) exploitative use has a stronger influence on DC for women than for men, while explorative use displays a higher impact on DC for men than for women, and (b) technology digital affordance (TDA), digital knowledge (DK), and task variety (TV) exhibit significant influences on both exploitative and explorative uses to varying extents. The post‐hoc analysis reveals that exploitative use mediates the influences of TDA and DK on DC only for women; explorative use mediates the impacts of TDA and TV on DC only for men. Our study advances the understandings of the downstream impact of technology use in the digital context.

AbstractObjectiveThe aim of this study is to investigate the histopathological and biochemical efficacy of vitamin D on oxidative damage and fibrosis in rat ovaries induced by experimental hyperthyroidism.MethodsThis study is a comparative, prospective experimental rat study. Sprague–Dawley female rats were divided into four groups. Only distilled water was given to the rats in group 1 for 25 days. In group 2, 100 μg/day L‐thyroxine was given to rats for 25 days. In Group 3, 100 μg/day L‐thyroxine and 200 IU/day vitamin D were given to rats for 25 days. In group 4, only 200 IU/day vitamin D was administered for 25 days.ResultsThis study is the first to demonstrate the protective effect of vitamin D against ovarian damage caused by experimental hyperthyroidism. Hyperthyroidism caused fibrotic degenerative changes in the ovaries and an increase in the fibrillin 1 score. It caused serum follicle‐stimulating hormone (FSH) levels to increase and serum E2 levels to decrease. In addition, malondialdehyde (MDA) and total oxidant status (TOS) levels increased in rats with hyperthyroidism. Vitamin D decreased MDA and TOS values and increased total antioxidant status (TAS) values in rats with hyperthyroidism. It also increased TSH values by causing a decrease in TT3 and TT4 values. It decreased fibrosis, follicle degeneration, stromal degeneration, and fibrillin 1 score in ovarian tissue.ConclusionVitamin D has positive histopathological and biochemical effects on the oxidative stress and follicle damage caused by hyperthyroidism in ovarian tissue. Human studies with larger case populations should be conducted to evaluate the effects and clinical applications of vitamin D.

ABSTRACTBACKGROUNDMost children do not eat enough fruits and vegetables (FV). Schools are a critical setting for supporting children to consume FV. To fill a gap in available materials, a classroom curriculum was developed and evaluated to determine impacts on student FV‐related knowledge, attitudes, and behaviors.METHODSA pre‐/post‐intervention survey was administered to 4th‐6th grade students in 3 intervention and one comparison schools. Post‐intervention student focus groups, parent/guardian surveys, and teacher surveys provided complementary information.RESULTSIntervention students had a significantly greater increase in total FV intake, fruit intake, and 100% juice consumption, and preference for several types of FV relative to comparison group students. Students, teachers, and parents reported overall high levels of satisfaction with the curriculum.CONCLUSIONSThe Harvest of the Month curriculum is effective at increasing fruit intake among a low‐income, diverse student population in grades 4‐6, is acceptable to students, teachers, and parents, and is feasible to implement. Findings suggest this impact is the result of changes in preferences, skills, and motivation but not self‐efficacy or perceived social norms. Some tailoring of the curriculum may be needed to increase its appropriateness for 6th‐grade students, increase the impact on vegetable intake, and limit intake of juice.

AbstractBackgroundArterial spin labeling (ASL) is a noninvasive brain perfusion magnetic resonance imaging (MRI) technique that has not been assessed in clinical veterinary medicine.Hypothesis/ObjectivesTo test the feasibility of ASL using a 1.5 Tesla scanner and provide recommendations for optimal quantification of cerebral blood flow (CBF) in dogs and cats.AnimalsThree hundred fourteen prospectively selected client‐owned dogs and cats.MethodsEach animal underwent brain MRI including morphological sequences and ≥1 ASL sequences using different sites of blood labeling and postlabeling delays (PLD). Calculated ASL success rates were compared. The CBF was quantified in animals that had morphologically normal brain MRI results and parameters of ASL optimization were investigated.ResultsArterial spin labeling was easily implemented with an overall success rate of 95% in animals with normal brain MRI. Technical recommendations included (a) positioning of the imaging slab at the foramen magnum and (b) selected PLD of 1025 ms in cats and dogs <7 kg, 1525 ms in dogs 7 to 38 kg, and 2025 ms in dogs >38 kg. In 37 dogs, median optimal CBF in the cortex and thalamic nuclei were 114 and 95 mL/100 g/min, respectively. In 28 cats, median CBF in the cortex and thalamic nuclei were 113 and 114 mL/100 g/min, respectively.Conclusions and Clinical ImportanceOur survey of brain perfusion ASL‐MRI demonstrated the feasibility of ASL at 1.5 Tesla, suggested technical recommendations and provided CBF values that should be helpful in the characterization of various brain diseases in dogs and cats.

AbstractQuestionsThe effects of agriculture on forest biodiversity and ecosystem properties can persist decades or centuries after abandonment. Many Pacific island nations are experiencing declines in traditional agriculture. Seed dispersal and seedling recruitment are critical to forest regeneration, and this is particularly relevant for Polynesia where native seed disperser diversity is low and species have been extirpated to crisis levels. In this study we asked: are secondary lowland tropical forests converging to mature forest, and are there seedling recruitment and survival differences between forest types?LocationThe Polynesian island of Tutuila, American Samoa, where traditional agriculture has been on the decline since the 1940s and secondary forests comprise 70% of all forest area.MethodsWe surveyed 34 vegetation plots (containing 2,232 adult trees and 6,579 tree seedlings) across mature forest and >50 years old secondary lowland rain forest. We quantitatively compared forest diversity, structure and the 3‐year seedling regeneration dynamics of the tree community.ResultsAlthough species richness and stem densities were similar between mature and secondary forest, most diversity and structure parameters remained distinguishable between the two forest types. Basal area remained significantly higher in mature forest; the diagnostic tree species of mature and secondary forest differed; and community composition (as indicated by NMDS) remained significantly different. However, seedling survivorship did not differ between forest types and seedling recruitment patterns indicated that there remained a suite of effective seed dispersers on Tutuila.ConclusionsWe conclude that (a) community differences between mature and secondary lowland rainforest were driven by the abundance of diagnostic species rather than exclusion of species from a forest type, and (b) there was no evidence of biophysical or ecological barriers to forest recovery of lowland secondary rain forest, or its convergence towards mature lowland rain forest. Nevertheless, more than 50 years after agricultural abandonment, secondary forest remains distinct from mature forest, highlighting that land use legacies are long‐term drivers of forest composition and successional trajectory in post‐agricultural landscapes of Polynesia.

AbstractThe purpose of this study was to evaluate the effect of time in culture on fatty acid composition of copepods Tisbe sp. and Apocyclops sp. For experiments, Tisbe and Apocyclops copepodites were separated and placed in 4‐L containers at 5 ind/mL. The fatty acids were evaluated at three different periods (hours) of culture (treatments): T1 = 6 hr, T2 = 12 hr, and T3 = 168 hr. Culture conditions were 25°C, salinity 35 ppt, illuminance 2,500 lx, with gentle aeration. The live food was Isochrysis galbana at 75 × 103 cells/mL. A total of 14 fatty acids were detected for both copepods. Although, there were absent two fatty acids for Apocyclops sp. (C18:3n‐6 and C18:1n‐7). The major percentages of fatty acids were more than 50% of polyunsaturated fatty acids. The essential fatty acids were detected such as C22:6n‐3 (docosahexaenoic acid [DHA]), C20:5n‐3 (eicosapentaenoic acid [EPA]), and C20:4n‐6 (arachidonic acid) for both species. Tisbe sp. was the species which shows the highest quantity of total lipids compared to Apocyclops sp. for the three treatments. Besides, in T3 both species had greater quantities of total lipids in respect to the first treatment. The ratio of DHA/EPA was optimal for culture of fish marine larvae because the proportion is higher than 2:1.
Novel findings in sea cucumber's digestive capacities: Enzymatic activities in the respiratory tree, implications for aquaculture

AbstractThere is a demand for proper feed and feeding strategies in the growing sea cucumber aquaculture. The digestive system of holothurians seems to increase nutrient assimilation through the respiratory tree (RT), but digestive functioning in this organ has not been investigated. This study evaluated the enzymatic activity of the cytosolic leucine alanine peptidase (leu‐ala) and acid phosphatase, the membrane‐linked aminopeptidase‐N (APN), the bile salt‐activated lipase, laminarinase (LAM), and β‐glycosidase (BGL), in the RT and segments of the digestive tract (DT; foregut, midgut, and hindgut) of adult Isostichopus badionotus. All enzymes, except LAM and BGL, exhibited comparable activity levels in the RT and the DT segments, but APN and BGL activities were significantly higher in the whole DT compared with those in RT, with high activity of leu‐ala in both organs. These results indicate a relevant role of the RT as an accessory organ in sea cucumber digestive physiology. Consequently, I. badionotus seems to be able to digest feeds from the water column through the RT, maximizing the use of available nutrients by luminal, intracellular, and apical membrane‐linked digestive modes. These findings expand the knowledge of sea cucumber digestive mechanisms, with implications for developing feeding strategies for all life stages in aquaculture.

AbstractIn many cooperatively breeding mammals, an unrelated dominant pair monopolizes reproduction in the social group while subordinates help to raise their offspring. In Kalahari meerkats (Suricata suricatta), dominant males are usually immigrants while dominant females are natal animals that have not left the group where they were born. However, in around 20% of cases, a natal male acquires and holds the dominant position – despite being closely related to the dominant female. Natal dominant males seldom mate within their group (either with the dominant female or with subordinate females) and the benefits they accrue from acquiring and maintaining the dominant position are not obvious. Here, we describe the circumstances in which natal males acquire dominance and explore the possible benefits they gain by comparing the life history, growth and behavioural differences between natal dominants, natal subordinates and immigrant dominants in wild groups. We show that natal dominant males do not appear to obtain any survival, nutritional or reproductive benefits from their status while they remain in the natal group. However, after dispersing from their natal group, they have a higher chance of acquiring dominant status in another breeding group, suggesting that acquiring dominance in their natal group has deferred direct fitness benefits for male meerkats.
Restorative nodes of governance in the Anthropocene: Iran's Kashaf River

Published: July 2021

AbstractThis article describes an environmental crisis in Iran that is actually a multidimensional crisis of law and policy. The article explores the restorative nodal governance response to such polycentric problems by weaving together five related ideas originating from criminologist and regulatory scholar Clifford Shearing: nodal governance; regulatory culture as a storybook (rather than a rulebook); justice as a better future; networked discovery of Awareness, Motivation, and Pathways for transformation; and a green ethic of care to guide transformation. We use an imaginary of a river to learn from a confluence of these ideas. They involve nodes of local governance organized by front‐line workers who restoried intertwined problems with an ethic of care. The challenge uncovered is that restorative microstrategies proved promising when steering powerless actors, but frayed when faced with factory owners. More aggressive strategies of nodal governance may bring forth more responsive escalation in order to confront privilege. Yet such strategies might be more creatively escalated as nodes of conversational regulation that reconfigure Shearing's five insights to transform landscapes of power. A coherence discovered inductively across these insights revolves around restorative nodal contestation of hegemony. Even lives as infused with domination as those found along the Kashaf River in Iran, where our case study is set, can be restored in counterhegemonic ways.

AbstractContextConflict during simulation debriefing can interfere with learning when psychological safety is threatened. Debriefers often feel unprepared to address conflict between learners and the literature does not provide evidence‐based guidance within the simulation setting. The purpose of this study was to describe debriefers' approach to mediating interpersonal conflict and explore when, why and how they adopt mediation strategies.MethodsWe performed a secondary analysis of qualitative data collected as part of a larger study examining simulation debriefers' approaches to debriefing scenarios with different learner characteristics. For this study, we applied thematic analysis to transcripts from simulated debriefings (n = 10) and the associated pre‐simulation (n = 11) and post‐simulation (n = 10) interviews that focused on interpersonal conflict between learners.ResultsDebriefers described struggling with mediating conflict and the importance of self‐awareness. Specific mediation strategies included intervening, addressing power relations, reconciling unproductive differences, leveraging different perspectives, circumventing the conflict, and shifting beyond the conflict; each of these strategies encompassed a number of particular skills. Situations that triggered a mediation approach were related to psychological safety, emotional intensity, and opportunities for shared understanding and productive learning. Debriefers applied mediation strategies and skills in a flexible and creative way.ConclusionsThe strategies we have described for mediating interpersonal conflict between learners in simulation debriefing align with notions of psychological safety and may be useful in guiding future professional development for simulation educators.

RésuméLe livre de poésie Ceux du lointain (2017) de Patricia Cottron‐Daubigné ressort à un versant de la littérature contemporaine qui s’intéresse aux représentations des personnes migrantes. L’objectif de cet article est de mettre en évidence les processus par lesquels l’auteure fait voir au lecteur la vie, et non la survie ou non‐vie, de migrants africains et d’une femme Rom, et l’entraîne vers la considération. À partir d’une perspective sémantico‐énonciative, seront envisagées la mise en abîme de l’écriture, la désignation des personnes migrantes, dont l’usage des pronoms personnels, l’attention aux valeurs humaines. Par ailleurs, cet article aborde la dimension résistante de Ceux du lointain.
Association of dexmedetomidine with recovery room and hospital discharge times: A retrospective cohort analysis

AbstractBackgroundDexmedetomidine is a useful anesthetic adjunct, increasingly popular during pediatric surgery and procedural sedation. Its half‐life of 2–3 hours might prolong recovery and discharge times when compared with an un‐supplemented propofol anesthetic. This may create an additional burden in a busy post‐anesthetic care unit (PACU).AimTo investigate whether intraoperative adjuvant dexmedetomidine delays PACU discharge in patients undergoing propofol anesthesia for day surgery or procedural investigations with minimal anticipated post‐procedural pain.MethodsWe conducted a retrospective review of outpatient procedures performed during a six‐month period including pediatric patients, ASA physical status I‐III, who underwent intravenous anesthesia with propofol and remifentanil for magnetic resonance imaging (MRI), strabismus repair, upper gastrointestinal endoscopy, or combined upper/lower gastrointestinal endoscopy. Patients receiving a sedative premedication, long‐acting opioids, or volatile anesthetics for maintenance of anesthesia, were excluded. Duration of PACU stay was compared for patients who did or did not receive intraoperative dexmedetomidine in the four procedure groups.ResultsCharts were reviewed for 359 patients; 130 (36%) received dexmedetomidine. Median differences in duration of PACU stay for dexmedetomidine versus non‐dexmedetomidine cases were: 5 minutes (95%CI 0 to 10, p=0.037) for MRI; 5 minutes (95%CI −3 to 15, p=0.258) for strabismus surgery; 7 minutes (95%CI 3 to 10, p<0.001) for upper endoscopy; and 5 minutes (95%CI 1 to 12, p=0.021) for combined upper/lower endoscopy. Linear regression (F=61.1, adjusted R2=0.40) indicated a significant relationship between dexmedetomidine dose (estimate 14.6 minutes per μg/kg, 95%CI 8.2 to 21.1, p<0.001) and duration of PACU stay.ConclusionWe found evidence for a small association of intraoperative dexmedetomidine with duration of recovery from propofol anesthesia for a set of common outpatient procedures, with a potential dose relationship equivalent to approximately 15 minutes delay per μg/kg dexmedetomidine administered. Future research into the benefits of dexmedetomidine in pediatric anesthesia should further evaluate this relationship.
