Conditions for Workplace Learning Among Professional ‘Temps’: A Qualitative Study of Temporary Agency Nurses in Sweden
Authors: Berg Jansson Anna , Engström Åsa 
Published: February 2022

AbstractAdopting a theoretical perspective that acknowledges both formal and informal learning as crucial and emphasises reproductive and developmental learning as complementary, this article analyses and discusses temporary agency nurses’ experiences of working and learning, focusing on conditions for workplace learning. This provides opportunities to address questions about conditions for the integration of work and learning in a work situation characterised by flexibilization and individualisation. More specifically, among individuals moving between different organizational contexts rather than working at ‘a’ (single and stable) workplace provided by the employer. By presenting findings based on a thematic analysis of 21 interviews with individual temporary agency nurses working in Swedish health care, both opportunities and challenges for workplace learning is highlighted. While opportunities for informal learning linked to the movement between various client organizations as well as to nursing as common ground and as valued and recognized competence, is identified, at the same time, challenges connected to both formal and informal learning, are also illuminated. Regarding informal learning, challenges in terms of varied and general support and feedback as well as scarce opportunities and low expectations for the temporary agency nurses’ participation in development work in daily work/at client organizations, is identified. The findings thus also illuminate a risk for temporary agency nurses adjusting to prevailing working conditions rather than engaging in developmental learning. Regarding formal learning, challenges in terms of few opportunities for planned learning activities, is identified. All in all, the findings illuminate conditions for workplace learning for temporary agency nurses as clearly dependent not only on the offers of specific temporary work agencies and client organisations, but also on temporary agency nurses’ interest in and views regarding responsibility for learning, and thus highly varying.

Published: February 2022

AbstractOlea europaea L. (olive, Oleaceae) constitutes a source of many bioactive compounds, which have recognized benefits for both human health and technological purposes. The present article was carried out to evaluate the biological activity of oleuropein (an ester of 2-(3,4-dihydroxyphenyl) ethanol (hydroxytyrosol) which has the oleosidic skeleton that is common to the secoiridoid glucosides of Oleaceae). It occurred in leaf extracts of the four olive cultivars (Chemlali, Manzanilla, Picaul and Toffahi) as a source for some anticancer and antioxidant agents and their consequences on the action of Hordeum vulgare (barley). The total phenolic and flavonoid compounds were extracted from olive leaves by ethanol 95% then analyzed by high-performance liquid chromatography (HPLC). The study evaluates the anticancer activity of the ethanolic extract of olive leaves against breast and hepatocellular carcinoma cells showing high values. Also, the extract exhibited highly consequence on the antioxidant potentiality of barley which was assessed using the diphenyl picryl hydrazyl method (DDPH). These results pave the way for utilization of olive leaves as a source of natural anticancer and antioxidant agents.
Data analytics and artificial intelligence in predicting length of stay, readmission, and mortality: a population-based study of surgical management of colorectal cancer

Published: February 2022

AbstractData analytics and artificial intelligence (AI) have been used to predict patient outcomes after colorectal cancer surgery. A prospectively maintained colorectal cancer database was used, covering 4336 patients who underwent colorectal cancer surgery between 2003 and 2019. The 47 patient parameters included demographics, peri- and post-operative outcomes, surgical approaches, complications, and mortality. Data analytics were used to compare the importance of each variable and AI prediction models were built for length of stay (LOS), readmission, and mortality. Accuracies of at least 80% have been achieved. The significant predictors of LOS were age, ASA grade, operative time, presence or absence of a stoma, robotic or laparoscopic approach to surgery, and complications. The model with support vector regression (SVR) algorithms predicted the LOS with an accuracy of 83% and mean absolute error (MAE) of 9.69 days. The significant predictors of readmission were age, laparoscopic procedure, stoma performed, preoperative nodal (N) stage, operation time, operation mode, previous surgery type, LOS, and the specific procedure. A BI-LSTM model predicted readmission with 87.5% accuracy, 84% sensitivity, and 90% specificity. The significant predictors of mortality were age, ASA grade, BMI, the formation of a stoma, preoperative TNM staging, neoadjuvant chemotherapy, curative resection, and LOS. Classification predictive modelling predicted three different colorectal cancer mortality measures (overall mortality, and 31- and 91-days mortality) with 80–96% accuracy, 84–93% sensitivity, and 75–100% specificity. A model using all variables performed only slightly better than one that used just the most significant ones.

Hegel's Truth: A Property of Things?
Authors: Giladi Tal Meir 
Published: February 2022

AbstractIn his Encyclopaedia Logic, Hegel affirms that truth is ‘usually’ understood as the agreement of thought with the object, but that in the ‘deeper, i.e. philosophical sense’, truth is the agreement of a content with itself or of an object with its concept. Hegel then provides illustrations of this second sort of truth: a ‘true friend’, a ‘true state’, a ‘true work of art’. Robert Stern has argued that Hegel's ‘deeper’ or ‘philosophical’ truth is close to what Heidegger labelled ‘material’ truth, namely a property attributed to a thing on the basis of the accordance of that thing with its essence. It has since been common to think of Hegel's concept of ‘philosophical’ truth as ‘ontological’, ‘objective’ or ‘material’ in contrast to ‘epistemological’ or ‘propositional’ definitions. In this paper, I wish to add an important nuance to the existing literature on this subject: even though things have a truth-value for Hegel, the latter is always negative. I argue that Hegel's criterion of ‘philosophical’ truth, which is best formulated as ‘agreement with self’, is first and foremost intended to examine the truth-value of thought-determinations. I then argue that even though this criterion may also be applied to examine the truth-value of things (namely, even though things have a truth-value), things never fall under this definition. After reviewing several of Hegel's explicit remarks on the matter, I provide an alternative explanation to those features of Hegel's ‘philosophical’ truth which have led scholars to view it as a truth in things. Especially, I argue that what are generally seen as Hegel's examples (‘true friend’, ‘true state’, ‘true work of art’) are not intended as examples but only as imperfect illustrations of ‘philosophical’ truth.

Abstract
The once-contiguous Ellesmere Ice Shelf, first reported in writing by European explorers in 1876, and now almost completely disintegrated, has rolling, wave-like surface topography, the origin of which we investigate using a viscous buckling instability analysis. We show that rolls can develop during a winter season (~ 100 d) if sea-ice pressure (depth-integrated horizontal stress applied to the seaward front of the Ellesmere Ice Shelf) is sufficiently large (1 MPa m) and ice thickness sufficiently low (1–10 m). Roll wavelength initially depends only on sea-ice pressure, but evolves over time depending on amplitude growth rate. This implies that a thinner ice shelf, with its faster amplitude growth rate, will have a shorter wavelength compared to a thicker ice shelf when sea-ice pressure is equal. A drawback of the viscous buckling mechanism is that roll amplitude decays once sea-ice pressure is removed. However, non-Newtonian ice rheology, where effective viscosity, and thus roll change rate, depends on total applied stress may constrain roll decay rate to be much slower than growth rate and allow roll persistence from year to year. Whether the viscous-buckling mechanism we explore here ultimately can be confirmed as the origin of the Ellesmere Ice Shelf rolls remains for future research.

AbstractProspective cohort studies linking organ meat consumption and non-alcoholic fatty liver disease (NAFLD) are limited, especially in Asian populations. This study aimed to prospectively investigate the association between organ meat consumption and risk of NAFLD in a general Chinese adult population. This prospective cohort study included a total of 15 568 adults who were free of liver disease, CVD and cancer at baseline. Dietary information was collected at baseline using a validated FFQ. NAFLD was diagnosed by abdominal ultrasound after excluding other causes related to chronic liver disease. Cox proportional regression models were used to assess the association between organ meat consumption and risk of NAFLD. During a median of 4·2 years of follow-up, we identified 3604 incident NAFLD cases. After adjusting for demographic characteristics, lifestyle factors, vegetable, fruit, soft drink, seafood and red meat consumption, the multivariable hazard ratios (95 % CI) for incident NAFLD across consumption of organ meat were 1·00 (reference) for almost never, 1·04 (0·94, 1·15) for tertile 1, 1·08 (0·99, 1·19) for tertile 2 and 1·11 (1·01, 1·22) for tertile 3, respectively (Pfor trend < 0·05). Such association did not differ substantially in the sensitivity analysis. Our study indicates that organ meat consumption was related to a modestly higher risk of NAFLD among Chinese adults. Further investigations are needed to confirm this finding.

AbstractObjectiveThe coronavirus disease 2019 pandemic has greatly disrupted head and neck cancer services in the West of Scotland. This study aimed to assess the impact of the first wave of the pandemic on cancer waiting times.MethodsA retrospective review of multidisciplinary team records was undertaken between March and May in 2019 and the same months in 2020. Time-to-diagnosis and time-to-treatment for new cancers treated with curative intent were compared between the study periods, and subclassified by referral pathway.ResultsA total of 236 new cancer patients were included. During the pandemic, pathways benefitted from reduced diagnostic and treatment times resulting from the restructuring of service provisions. A 75 per cent reduction in secondary care referrals and a 33 per cent increase in urgent suspicion of cancer referrals were observed in 2020.ConclusionHead and neck cancer pathway times did not suffer because of the coronavirus pandemic. Innovations introduced to mitigate issues brought about by coronavirus benefitted patients, led to a more streamlined service, and improved diagnostic and treatment target compliance.
Coverage control of mobile agents using multi-step broadcast control

Published: February 2022

AbstractThis paper proposes a novel multi-step broadcast control (MBC) scheme to deploy a group of autonomous mobile agents for accomplishing coverage tasks in a bounded region. Traditional broadcast control (BC) schemes use a one-to-all communication framework to transmit a uniform signal to all agents, making it cost-effective compared with any all-to-all communication-based scheme for a multi-agent system. However, as BC schemes are based on a single-step view of the environment for decision-making, the environment’s varying distribution density is not known immediately to the agents, resulting in suboptimal performance. To overcome this drawback, this paper proposes an MBC scheme, where agents use a predictive multi-step view and are able to detect the varying densities in the environment ahead of time. The local controller output is estimated using a weighted averaging technique which assigns a higher weight to immediate steps; this feature compensates for any decrease in prediction accuracy as the number of steps increases. We demonstrate the effectiveness of the proposed MBC scheme using a coverage task over a region with uneven population density. Compared to existing BC schemes, the proposed MBC scheme shows superior convergence characteristics in task accomplishment and deployment efficiency.
Early-career scholars and scholarship: A social justice perspective
Authors: Habibie Pejman 
Published: February 2022

AbstractThis paper focuses on the concept of social (in)justice to examine and discuss some of the areas in the production and dissemination of knowledge in which the issue of social justice is significant and should be applied and considered. More specifically, it explores and advocates for some of the ways in which participation in, and contribution to, global scholarship can become a more socially just practice for academics, especially novice scholars and early-career researchers in the field of Applied Linguistics. It also highlights the role and agentive engagement of both established and junior members of academic communities as an important factor in demonopolizing and democratizing academic discourses and practices and making the mobilization of scholarship more diverse, inclusive, multivocal, and transformative.
The spectrum of a localic semiring
Authors: MANUELL GRAHAM 
Published: February 2022

AbstractA number of spectrum constructions have been devised to extract topological spaces from algebraic data. Prominent examples include the Zariski spectrum of a commutative ring, the Stone spectrum of a bounded distributive lattice, the Gelfand spectrum of a commutative unital C*-algebra and the Hofmann–Lawson spectrum of a continuous frame.Inspired by the examples above, we define a spectrum for localic semirings. We use arguments in the symmetric monoidal category of suplattices to prove that, under conditions satisfied by the aforementioned examples, the spectrum can be constructed as the frame of overt weakly closed radical ideals and that it reduces to the usual constructions in those cases. Our proofs are constructive.Our approach actually gives ‘quantalic’ spectrum from which the more familiar localic spectrum can then be derived. For a discrete ring this yields the quantale of ideals and in general should contain additional ‘differential’ information about the semiring.
Uniform bounds for norms of theta series and arithmetic applications
Authors: WAIBEL FABIAN 
Published: February 2022

AbstractWe prove uniform bounds for the Petersson norm of the cuspidal part of the theta series. This gives an improved asymptotic formula for the number of representations by a quadratic form. As an application, we show that every integer$n \neq 0,4,7 \,(\textrm{mod}\ 8)$is represented as$n= x_1^2 + x_2^2 + x_3^3$for integers$x_1,x_2,x_3$such that the product$x_1x_2x_3$has at most 72 prime divisors.
Transnational networked authority
Authors: Perez Oren 
Published: February 2022

AbstractThe structure of the global governance system has undergone significant changes in the past few years. From a system governed primarily by global public law institutions established through multilateral treaties, it has metamorphosed into a hybrid field in which a plethora of public, private, and semi-public institutions interact in various ways. The shift to a hybrid global governance architecture presents a complex challenge for legal and political theory, with immense policy implications. In the present article, I respond to this challenge by developing a new model of transnational legal authority, which conceptualizes it as an emergent, network-based phenomenon. According to this model, the emergence of transnational networked authority is dependent on the existence of a multi-layered structure of strongly connected transnational regimes. Key factors in the emergence of networked authority are the normative and compliance synergies that arise through the densification of links across the network. I examine in this context the linkage between the sociological and the jurisprudential aspects of the authority of private transnational regulatory regimes, and develop the idea of ‘network grounding’, which emphasizes the relational structure of private transnational legality. I illustrate the thesis by reviewing findings from a network analysis of transnational corporate social responsibility networks.

Abstract
After the introduction of the 13-valent pneumococcal conjugate vaccine (PCV13), serotype replacement has occurred in Japan, and serotype 24 has become the most common serotype in paediatric invasive pneumococcal disease (IPD). To understand the characteristics of serotype 24-IPD in Japanese children in the post-PCV13 era, we conducted a retrospective study in children aged ≤15 years from 2010 to 2020 using a database of paediatric IPD surveillance in Chiba prefecture, Japan. We identified a total of 357 IPD cases and collected clinical information on 225 cases (24: 32 cases, non-24: 193 cases). Compared with the non-serotype 24-IPD, serotype 24-IPD was independently related to be <2 years of age [odds ratio (OR) 3.91, 95% confidence interval (CI) 1.47–10.44; P = 0.0064] and bacteremia (OR 2.28, 95% CI 1.01–5.13; P = 0.0475), as a result of the multivariate regression analysis. We also conducted a bacterial analysis, and the isolates of serotype 24-IPD had tendencies of PCG-susceptible (24: 100.0%, non-24: 61.3%; P < 0.0001) and macrolide-resistance (24: 100.0%, non-24: 87.3%; P = 0.0490). Their multilocus sequence typing was mostly ST2572 and the variants, which were unique to Japan. This tendency might have been a result of the progress made in the Japanese PCV13 immunisation programme.
Population size, abundance, habitat relationships and the result of a translocation programme in the Gran Canaria Blue ChaffinchFringilla polatzeki

Published: February 2022

SummaryThe Gran Canaria Blue ChaffinchFringilla polatzekiis a threatened, endemic, forest‐dwelling bird species of the Canary Islands, whose core population at the end of the 20th century was restricted to the pine forests of Inagua Nature Reserve (38 km2). A translocation programme released birds from a breeding centre into the nearby (<3 km) pine forests of La Cumbre in the years following 2010. From 2015 to 2019 the La Cumbre population was reinforced by translocation of wild juveniles from the source population of Inagua. We estimate the population size, the spatial variation of abundance, and recent temporal changes in density of the species in Inagua and La Cumbre by means of line transects, distance sampling, and habitat suitability modelling using random forests. The average density of the Blue Chaffinch in Inagua Nature Reserve was 10.2 birds/km2in spring 2019, with a population estimated at 362 birds (95% CI: 257–489). The most important variables affecting the distribution of the Blue Chaffinch in Inagua were the amount of precipitation during the summer (July–September), the solar radiation in June, and the northern position in the reserve, highlighting the importance of abiotic factors related to thermal and hydric stress during the breeding season. The density was considerably lower in the translocated population inhabiting 21 km2of pine forests in La Cumbre (3.3 birds/km2), with an estimate of 68 Blue Chaffinches (35–141) breeding freely in the wild. The translocation programme successfully contributed to the establishment of a second viable nucleus, accounting for 16% of the total population within a time span of 10 years. This result reinforces the role of translocations in preventing extinctions of endangered species with very low population sizes restricted to only one isolated area.

SummaryTo explore whether embryo culture with melatonin (MT) can improve the embryonic development and clinical outcome of patients with repeated cycles after in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) failure, immature oocytes from controlled ovarian superovulation cycles were collected for in vitro maturation (IVM) and ICSI. The obtained embryos were cultured in 0, 10–11, 10–9, 10–7 and 10–5 M MT medium respectively, and 10–9 M was screened out as the optimal concentration. Subsequently, 140 patients who underwent failed IVF/ICSI cycles received 140 cycles of embryo culture in vitro with a medium containing 10–9 M MT, these 140 MT culture cycles were designated as the experimental group (10–9 M group), and the control group was the previous failed cycles of patients (0 M group). The results showed that the fertilization, cleavage, high-quality embryo, blastocyst, and high-quality blastocyst rates of the 10–9 M group were significantly higher than those of the 0 M group (P < 0.01; P < 0.01; P < 0.0001; P < 0.0001; P < 0.0001). To date, in total, 50 vitrified-warmed cycle transfers have been performed in the 10–9 M group and the implantation rate, biochemical pregnancy rate and clinical pregnancy rate were significantly higher than those in the 0 M group (all P < 0.0001). Two healthy infants were delivered successfully and the other 18 women who achieved clinical pregnancy also had good examination indexes. Therefore the application of 10–9 M MT to embryo cultures in vitro improved embryonic development in patients with repeated cycles after failed IVF/ICSI cycles and had good clinical outcomes.Trial registration: ChiCTR2100045552.
