How do signature pedagogies get their signatures? The role of assessment and professional artefacts in preparing students for their professions

ABSTRACT Signature pedagogies are widely used in professional education to prepare students for the complex and unpredictable nature of professional work. We argue that assessment moments involving professional artefacts contribute to the evaluation and formation of professional knowledge, skills and moral understandings – and thus to the signature of the pedagogy. The ‘authenticity’ these professional artefacts add to assessment is of particular relevance for understanding the pedagogic signature. Drawing on interviews from a professional study programme in dental hygiene, we employ sociocultural theories to analyse how different assessment moments are used to evaluate and develop students’ competences of working with professional artefacts: dental radiographs. The findings show how the use of professional artefacts in three different assessment moments requires students to engage deeply with the epistemic, practical and moral dimensions of their profession. Our study contributes both empirical and conceptual insights to the field’s understanding of the inner workings of signature pedagogies.
Firm Responses to Violent Conflicts

We estimate dynamic treatment effects of violent political conflicts on firm decisions to purchase inventory. We analyze monthly purchase data of 431 clients of a multinational beverage firm in Mozambique, as well as annual survey data. Firms respond to increases in conflict by decreasing purchases of inventory by up to 15%. This effect is significantly more pronounced for smaller firms. Firms exposed to violent conflicts also show greater intention to expand to less violent locations. The eruption of violent conflicts have significant short-term economic impact for small firms however, these do not persist beyond 2 months.
Between merchant network and memory work: Islamic cosmopolitanism along the Silk Road

Abstract In the studies of Islamic cosmopolitanism in Asia, merchant networks and religious mobility have received much scholarly attention in the past two decades. Yet, more studies are still needed to understand how memory work—especially the historical memory of trauma among diasporic communities—contributes to the transnational connections in Muslim Asia. Situated in the context of the Belt and Road Initiative (BRI), this article focuses on how merchant networks and memory work contribute to fostering Islamic cosmopolitanism in Asia. Building upon fieldwork between 2015 and 2020, my ethnography reveals that remembrance rituals and survival narratives become entangled with the merchant networks as Sinophone Muslims move between China and Central Asia. While striving to preserve the memory of historical trauma through rituals, Muslim individuals and associations also selectively downplay the past of ethnoreligious conflicts through heritage performance. In other words, Sinophone Muslims turn to traumatic memory through both remembering and selective oblivion, which is key to facilitating connections beyond the official BRI discourse.
Classification and Predictions of Lung Diseases from Chest X-rays Using MobileNet V2

Featured Application: The method presented in this paper can be applied in medical computer systems for supporting medical diagnosis.Abstract: Thoracic radiography (chest X-ray) is an inexpensive but effective and widely used medical imaging procedure. However, a lack of qualified radiologists severely limits the applicability of the technique. Even current Deep Learning-based approaches often require strong supervision, e.g., annotated bounding boxes, to train such systems, which is impossible to harvest on a large scale. In this work, we proposed the classification and prediction of lung pathologies of frontal thoracic X-rays using a modified model MobileNet V2. We considered using transfer learning with metadata leverage. We used the NIH Chest-Xray-14 database, and we did a comparison of performance of our approach to other state-of-the-art methods for pathology classification. The main comparison was by Area under the Receiver Operating Characteristic Curve (AUC) statistics and analyzed the differences between classifiers. Overall, we notice a considerable spread in the achieved result with an average AUC of 0.811 and an accuracy above 90%. We conclude that resampling the dataset gives a huge improvement to the model performance. In this work, we intended to create a model that is capable of being trained, and modified devices with low computing power because they can be implemented into smaller IoT devices.
Diagnostic Imaging of Foreign Bodies and Compartmentalization in the Canine Manus

Injury of the manus is an important cause of morbidity and function loss in dogs, especially working breeds. These injuries may cause foreign body retention and can lead to persistent infection. Accurate methods for diagnosis and localization of pathology in this anatomically complex region are critical to minimize patient morbidity, guide surgical planning, and improve case outcomes. The anatomy of the canine manus was evaluated with computed tomography (CT), magnetic resonance imaging (MRI), and transverse anatomic sections. Most structures identified on transverse sections were visible on both CT and MRI images. Detail in the osseous structures was better in CT images, while MRI provided increased contrast of soft-tissue structures. To test the hypothesis that diagnostic accuracies of CT, MRI, and ultrasound differ for detection of acute wooden foreign bodies in the canine manus, we inserted wooden splinters into canine cadaver manus and imaged each manus with all three modalities. Receiver operating characteristic curve analysis demonstrated that CT was most accurate for detection of acute wooden foreign bodies, followed in turn by ultrasound and MRI. Diseases in the human hand and foot are often confined by soft-tissue spaces, but similar structures have not been described in the dog. To determine if these spaces are present in the canine manus, we injected contrast medium into likely spaces and compartments in cadaver specimens, imaged the limbs with CT, and dissected the injected manus specimens. We found thirteen discrete soft-tissue spaces and five myofascial compartments that are similar to those described in the human hand.
Semiotics of rape in Pakistan: What’s missing in the digital illustrations?

What remains invisible in the discourse, contributes to perpetuating multilayered inequalities through discourse. Stereotypical representations, under-representations, hyper-representations, or misrepresentations regulate rape myths, and consequently, particular ways of seeing and behaving of those inside or outside the cultural boundaries. It has, therefore, been studied if and how rape victims and perpetrators have been visually represented and framed in the digital illustrations on rape in Pakistan. Discrepancies concerning identity construction of the rape victims and rapists as well as the depiction of multifarious socio-semiotic dimensions of rape have been analyzed. Thirty-five digital illustrations appearing in 32 blogs and news articles published on rape cases in Pakistan have been purposively selected and studied based on ideational metafunction suggested by Kress and van Leeuwen. Results reveal under-representation of rapists and perpetrators, law enforcement, survivors, and existing myths regarding revenge rape, child abuse, gang rape, marital rape, and gender-based victimhood. The study has implications for semiotics, rape studies, gender studies, and digital discourse.
Deconstructing accessibility – discursive barriers for increased cycling in Sweden

ABSTRACT Society’s planning for and dependence on automobility has created several major problems and calls for a shift away from car-based mobility are proliferating. There is a growing recognition of the positive effects of cycling and modal shares for cycling are on the rise in cities. Nevertheless, bicycling is still marginalised in national transport policies. In Sweden, cycling shares are decreasing at a national level, and to steer towards increased cycling, a policy shift is needed. We adopt a post-structuralist view and consider a policy shift to be a discursive shift. With the help of Laclau and Mouffe’s discourse theory, the paper depicts the position of cycling in Swedish national transport policy. As accessibility is a key concept in national transport policy and planning, we consider the meaning bestowed upon this concept paramount with regard to the marginalisation of cycling at the national level. The lack of decisiveness in national bicycle policy can be traced back to a suppression of certain meanings of accessibility. This calls for a reinterpretation of accessibility and a revaluation of the national responsibility for cycling. The framing of cycling as a local and primarily urban issue hampers the pro-activity of the national government regarding cycling.
Optical Temperature Sensing of YbNbO4:Er3+ Phosphors Synthesized by Hydrothermal Method

The novel YbNbO4:Er3+ phosphors were firstly synthesized through the hydrothermal method by adding LiOH·H2O as flux in the H2O/EG system. YbNbO4:Er3+ phosphors showed the agglomerated irregular polygons coexisting with some tiny grains. XRD and Raman spectra were measured to understand the phase structure and the crystal growth mechanism of YbNbO4:Er3+ phosphors. The upconversion (UC) emission spectra, the pump power dependency and UC mechanism were studied under 980 nm excitation. Based on the fluorescence intensity ratio technique, YbNbO4:Er3+ exhibited the maximum sensor sensitivity of 0.00712 K−1 at 220 K, providing a promising application in optical low-temperature sensors.
Midwives and Humanitarian Bureaucracy: Managing Migration at a Postcolonial Border

Drawing on Foucauldian biopolitics, Max Weber's and Hannah Arendt's understandings of bureaucracy, and Achille Mbembe's theoretical insights into necropolitical power, I propose the notion of humanitarian bureaucracy to account for the involvement of medical personnel in the summary deportations of pregnant Comorian women in Mayotte, a French overseas department in the Indian Ocean. In addition to their usual consultations, hospital midwives are asked to assess the health of pregnant women arrested at sea in order to state whether they can be lawfully detained, while deportations happen within hours owing to the specificities of this postcolonial migration regime. The notion of humanitarian bureaucracy traces how a series of bureaucratic acts, duly sanctioned by qualified professionals, performs a minimal and fragmented biopolitical surveillance that neutralizes the question of responsibility and rejects the racialized Other into a liminal space between failing to “make live” and avoiding to “let die. ” The article argues that humanitarian bureaucracy represents an ambivalent power, stemming from biopolitics yet producing necropolitics through processes of racialization. The article draws on three months of fieldwork conducted in Mayotte in 2017 and analyzes midwives’ discourses and bureaucratic practices as materialized by the medical certificates they deliver in the context of these assessments.
Evaluating and Strengthening the Health System of Curaҫao to Improve its Performance for Future Outbreaks of Infectious Diseases.

BackgroundVector-borne diseases (VBDs) such as dengue, chikungunya, and Zika pose a significant challenge to health systems in countries they affect, especially countries with less developed healthcare systems. Therefore countries are encouraged to strengthen their healthcare systems to achieve more resilient systems. This qualitative study aims to examine the performance of the health system of the Dutch Caribbean island of Curaҫao with regards to the prevention and control of VBDs in the last decennium by using the WHO health system building blocks.MethodsFrom January 2019 to February 2020, a multi-method qualitative study was performed in Curaçao. , applying content analysis of documents (n = 50), five focus group discussions (n = 30), interviews with experts (n = 11), and fifteen observation sessions. The study was designed based on the WHO framework: health system building blocks. Two cycles of inductive and deductive coding were employed, and Nvivo software was used to analyse the data.ResultsThis study’s data highlighted the challenges (e.g., insufficient oversight, coordination, leadership skills, structure, and communication) that the departments of the health system of Curaҫao faced during the last three epidemics of VBDs (2010–2020). Furthermore, low levels of collaboration between governmental and non-governmental organisations (e.g., semi-governmental and private laboratories) and insufficient capacity building to improve skills (e.g., entomological, surveillance skills) were also observed. Lastly, we observed how bottlenecks in one building block negatively influenced other building blocks (e.g., inadequate leadership/governance obstructed the workforce's performance). ConclusionsThis study uncovers potential organisational bottlenecks that have affected the performance of the health system of Curaҫao negatively. We recommend starting with the reinforcement of oversight of the integrated vector management program to ensure the development, implementation, and evaluation of related legislation, policies, and interventions. Also, we recommend evaluating and reform the existing administrative and organisational structure of the health system by taking the cultural style, challenges, and barriers of the current health system into account. More efforts are needed to improve the documentation of agreements, the recruitment, and evaluation of the workforce's performance. Based on our findings, we conceptualised actions to strengthen the health system's building blocks to improve its performance for future outbreaks of infectious diseases.

The method has been applied to determine cephadroxil in pharmaceutical preparations.
Can manipulatives help students in the third and fifth grades understand the structure of word problems?

Abstract Little is known about whether manipulatives can support children’s inferences of the mathematical structure of word problems. The objective was to test the effects of using manipulatives during problem solving on students’ understanding of the additive relationships in word problems. Third and fifth graders (N = 45) solved one-step addition and subtraction word problems that described either a mathematical action or relation. Children in each grade were randomly assigned to either a manipulatives or a paper-and-pencil condition. Problem structure understanding was assessed by the degree to which students’ strategies and verbal justifications reflected the quantitative relationships described in the problem text. Performance of the fifth graders was not impacted by the use of manipulatives, but in the third grade, strategy performance with manipulatives was superior to performance without manipulatives on Relation problems. The degree to which the third graders’ justifications were aligned with corresponding problem structure was positively impacted by manipulatives regardless of problem type.
Effect of Zn, Fe and Cu Content on Phytochemical Investigations and Antimicrobial Potential of Alternanthera brasiliana (L.) O. Kuntze Leaf Extracts Procured From Two Different States of India

The effect of zinc (Zn), iron (Fe) and copper (Cu) on phytoconstituent content and the potential antibacterial activity of three different leaf extracts of Alternanthera brasiliana (AB) against pathogenic bacteria, procured from two different states of India, was evaluated. Shade dried leaf samples were separately determined for Zn, Fe and Cu content through atomic absorption spectrophotometer (AAS). Further extraction was carried out using aqueous, methanol and mixture of aqueous and methanol (1:1) and microbioside potential were evaluated by agar well diffusion technique. Ampicillin (30µg/mL) was used as standard. The Minimum Inhibition Concentration (MIC) of all the extracts was carried out by serial dilution method and thereafter inhibitory microbial activity was carried out by agar plate method. The amount of Zn, Fe and Cu were higher in West Bengal sample. Furthermore, the concentration dependent ( ** P<0.05) potential antimicrobial activity was observed. At the dose of 200 mg/mL, combined aqueous and methanol extract of AB (ABAE and ABME respectively) from West Bengal, gave significant results against gram positive bacteria where maximum zone of inhibition was recorded against Straphyloccus aureus (13.0 ± 0.011 ** ). Such variation may be due to the geographical location of the plant, soil pH, content of elements and on the effects of choice of solvent.

Comparative Performance Evaluation of Commercial Packing Materials for Malodorants Abatement in Biofiltration

Packing materials used in biofiltration of gaseous pollutants represent a key design parameter, as a proper selection might not only determine the adequate performance of the system but also its cost-effectiveness. This study systematically assessed and compared the performance of a conventional plastic carrier with that of two novel clay-based materials from SAINT GOBAIN for the abatement of a model odorous stream composed of H2S, methylmercaptan and toluene. The packing materials were tested in biotrickling filters, biofilters and a two-phase biotrickling filter. SAINT GOBAIN materials exhibited a higher adsorption potential under abiotic conditions, a higher buffer capacity and a superior performance compared to conventional plastic rings when implemented in biotrickling filters operating at gas residence times as low as 7.5 s. Among the materials tested in biofilters, Filtralite Air AC supported almost complete H2S and toluene removals at a gas residence time of 20 s, while successfully eliminating methylmercaptan at values of ~80%. Interestingly, under most of the conditions tested, clay-based materials also showed comparable pressure drop values than those of plastic rings.
Turning to the dark side: LED light at night alters the activity and species composition of a foraging bat assemblage in the northeastern United States

Abstract Artificial light at night (ALAN) is a rapidly intensifying form of environmental degradation that can impact wildlife by altering light‐mediated physiological processes that control a broad range of behaviors. Although nocturnal animals are most vulnerable, ALAN's effects on North American bats have been surprisingly understudied. Most of what is known is based on decades‐old observations of bats around street lights with traditional lighting technologies that have been increasingly replaced by energy‐efficient broad‐spectrum lighting, rendering our understanding of the contemporary effects of ALAN on North American bats even less complete. We experimentally tested the effects of broad‐spectrum ALAN on presence/absence, foraging activity, and species composition in a Connecticut, USA bat community by illuminating foraging habitat with light‐emitting diode (LED) floodlights and comparing acoustic recordings between light and dark conditions. Lighting dramatically decreased presence and activity of little brown bats (Myotis lucifugus), which we detected on only 14% of light nights compared with 65% of dark (lights off) and 69% of control (lights removed) nights. Big brown bat (Eptesicus fuscus) activity on light nights averaged only half that of dark and control nights. Lighting did not affect presence/absence of silver‐haired bats (Lasionycteris noctivagans), but decreased their activity. There were no effects on eastern red bats (Lasiurus borealis) or hoary bats (L. cinereus), which have been described previously as light‐tolerant. Aversion to lighting by some species but not others caused a significant shift in community composition, thereby potentially altering competitive balances from natural conditions. Our results demonstrate that only a small degree of ALAN can represent a significant form of habitat degradation for some North American bats, including the endangered little brown bat. Research on the extent to which different lighting technologies, colors, and intensities affect these species is urgently needed and should be a priority in conservation planning for North America's bats.
A Global Empirical Model of Electron Density Profile in the F Region Ionosphere Basing on COSMIC Measurements

The topside ionosphere accounts for a dominant part of the ionospheric total electron content, whereas accurate global modeling of topside ionospheric electron density (Ne) profile has not been fully achieved. In this study, a high precision Ne profile model, named α‐Chapman Based Electron Density Profile Model (α‐Chapman‐Based‐EDP), was built by using ∼4.5 million Ne profiles from the Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC‐1) radio occultations. We first describe each of the profiles using five parameters of the α‐Chapman function, that is, peak density (NmF2) and height (hmF2) of F2 layer, scale height (Hm) as well as its altitude change rates, and then built a model for each of the parameters as a function of latitude, longitude, month, local time, and solar activity, through Empirical orthogonal function (EOF) analysis and Fourier expansion. Combining all the five models, we construct the α‐Chapman‐Based‐EDP. Compared with observations from COSMIC‐1 and ‐2, the model captures the ionospheric climatology well, such as solar activity dependence, seasonal variation, and spatial pattern, including the equatorial ionization anomaly and midlatitude trough as well as their variabilities. Our model can describe nearly 80% variability of Ne in F region. In contrast, the IRI2016 cannot well reproduce these characteristics, with errors higher than our model. The potential applications of our model were also discussed. A dense matrix data calculated by the model will be released in https://www.researchgate. net/profile/Qiaoling_Li5 with the permissions of COSMIC organizations.
