Reimagining GIS Instruction through Concept-Based Learning
Authors: Lafia Sara , Zhu Rui , Regalia Blake , Kuhn Werner
Published: June 2021

Abstract. Research in geographic information science has not yet found clear answers to the questions of what geographic information is about or what a geographic information system (GIS) contains. This lack of consensus makes it especially challenging to teach and learn GIS. Existing pedagogical approaches either focus on the representational level of data (e.g., “raster and vector”) or are too generic (e.g., “geo-referenced information”). This characterization of GIS and its content is difficult for learners to transfer and apply broadly. As instructors, we approach the challenge of teaching GIS from a conceptual basis. We describe our process to develop a set of core concepts of spatial information, which we use to redesign an undergraduate-level introductory GIS course. Our intervention focuses instruction on the kinds of questions that geographic information enables before training students to produce workflows and answers through system commands. The course redesign complements and informs ongoing research on core concepts of spatial information. Our results demonstrate that GIS courses can deliver more than software training, indicating both theoretical gains and didactic challenges.

Published: June 2021

Abstract. We consider the problem of reconstructing the number size distribution (or particle size distribution) in the atmosphere from lidar measurements of the extinction and backscattering coefficients. We assume that the number size distribution can be modelled as a superposition of log–normal distributions, each one defined by three parameters: mode, width and height. We use a Bayesian model and a Monte Carlo algorithm to estimate these parameters. We test the developed method on synthetic data generated by distributions containing one or two modes, and perturbed by Gaussian noise, and on three real datasets obtained from AERONET. We show that the proposed algorithm provides satisfactory results even when the assumed number of modes is different from the true number of modes, and substantially excellent results when the right number of modes is selected. In general, an over-estimate of the number of modes provides better results than an under-estimate. In all cases, the PM1, PM2.5 and PM10 concentrations are reconstructed with tolerable deviations.
Latent heating profiles from GOES-16 and its comparison to heating from NEXRAD and GPM
Authors: Lee Yoonjin , Kummerow Christian D. , Zupanski Milija
Published: June 2021

Abstract. Latent heating (LH) is an important quantity in both weather forecasting and climate analysis, being the essential factor driving convective systems. Yet, inferring LH rates from our current observing systems is challenging at best. For climate studies, LH has been retrieved from the Precipitation Radar (PR) on the Tropical Rainfall Measuring Mission (TRMM) using model simulations in the look-up table (LUT) that relates instantaneous radar profiles to corresponding heating profiles. These radars, first on TRMM and then Global Precipitation Measurement (GPM), provide a continuous record of LH. However, with observations approximately 3 days apart, its temporal resolution is too coarse to be used to initiate convection in forecast models. In operational forecast models such as High-Resolution Rapid Refresh (HRRR), convection is initiated from LH derived from ground based radar. Despite the high spatial and temporal resolution of ground-based radars, one disadvantage of using it is that its data are only available over well observed land areas. This study suggests a method to derive LH from the Geostationary Operational-Environmental Satellite-16 (GOES-16) in near-real time. Even though the visible and infrared channels on the Advanced Baseline Imager (ABI) provide mostly cloud top information, rapid changes in cloud top visible and infrared properties, when coupled to a LUT similar to those used by the TRMM and GPM radars, can equally be used to derive LH profiles for convective regions using model simulations coupled to a convective classification scheme and channel 14 (11.2 μm) brightness temperature. Convective regions detected by GOES-16 are assigned LH from the LUT, and they are compared with LH from NEXRAD and one of Dual-frequency Precipitation Radar (DPR) products, Goddard Convective-Stratiform Heating (CSH). LH obtained from GOES-16 show similar magnitude with NEXRAD and CSH, and vertical distribution of LH is also very similar with CSH. Overall, GOES LH appear to have the ability to mimic LH from radars, although the area identified as convective is roughly 25 % smaller than the current HRRR model, while the heating is correspondingly higher.
Evaluation of the dynamic core of the PALM model system 6.0 in a neutrally stratified urban environment: comparison between LES and wind-tunnel experiments
Authors: Gronemeier Tobias , Surm Kerstin , Harms Frank , Leitl Bernd , Maronga Björn , Raasch Siegfried
Published: June 2021

Abstract. We demonstrate the capability of the PALM model system version 6.0 to simulate neutrally stratified urban boundary layers.
Our simulation uses the real-world building configuration of the HafenCity area in Hamburg, Germany.
Using PALM's virtual measurement module, we compare simulation results to wind-tunnel measurements of a downscaled replica of the study area.
Wind-tunnel measurements of mean wind speed agree within 5 % on average while the wind direction deviates by approximately 4∘.
Turbulence statistics similarly agree.
However, larger differences between measurements and simulation arise in the vicinity of surfaces where building geometry is insufficiently resolved.
We discuss how to minimize these differences by improving the grid layout and give tips for setup preparation.
Also, we discuss how existing and upcoming features of PALM like the grid nesting and immersed boundary condition help improve the simulation results.

Published: June 2021

Abstract. The Arctic–boreal zone (ABZ) is experiencing amplified warming, actively
changing biogeochemical cycling of vegetation and soils. The
land-to-atmosphere fluxes of CO2 in the ABZ have the potential to
increase in magnitude and feedback to the climate causing additional large-scale warming. The ability to model and predict this vulnerability is critical
to preparation for a warming world, but Earth system models have biases that
may hinder understanding of the rapidly changing ABZ carbon fluxes. Here we
investigate circumpolar carbon cycling represented by the Community Land Model
5 (CLM5.0) with a focus on seasonal gross primary productivity (GPP) in plant
functional types (PFTs). We benchmark model results using data from satellite
remote sensing products and eddy covariance towers. We find consistent biases
in CLM5.0 relative to observational constraints: (1) the onset of deciduous
plant productivity to be late; (2) the offset of productivity to lag and
remain abnormally high for all PFTs in fall; (3) a high bias of grass, shrub,
and needleleaf evergreen tree productivity; and (4) an underestimation of
productivity of deciduous trees. Based on these biases, we focus on model
development of alternate phenology, photosynthesis schemes, and carbon
allocation parameters at eddy covariance tower sites. Although our
improvements are focused on productivity, our final model recommendation
results in other component CO2 fluxes, e.g., net ecosystem exchange
(NEE) and terrestrial ecosystem respiration (TER), that are more consistent
with observations. Results suggest that algorithms developed for lower
latitudes and more temperate environments can be inaccurate when extrapolated
to the ABZ, and that many land surface models may not accurately represent
carbon cycling and its recent rapid changes in high-latitude ecosystems,
especially when analyzed by individual PFTs.

Organización parroquial de las villas nuevas reales en la diócesis de León: Mansilla de las Mulas, Mayorga de Campos y Rueda del Almirante
Authors: Pérez Mariel
Published: June 2021

El presente trabajo analiza los procesos de organización eclesiástica que tuvieron lugar en las villas nuevas reales de la diócesis de León a partir de la repoblación llevada a cabo en las últimas décadas del siglo XII por Fernando II y Alfonso IX, poniendo el foco de atención en los casos de Mansilla de las Mulas, Mayorga de Campos y Rueda del Almirante. La constitución de estas villas como pueblas reales y su consiguiente crecimiento demográfico hicieron necesaria una adecuación de las estructuras parroquiales a los nuevos patrones de poblamiento, lo que implicó la construcción de nuevas iglesias, la negociación de los derechos de patronato y del reparto de los diezmos, y la delimitación de los territorios parroquiales. Estos procesos fueron impulsados y controlados por el episcopado leonés; sin embargo, su dinámica y resultados estuvieron condicionados en gran medida por las relaciones establecidas con las élites urbanas.

Se viene insistiendo en que la fortaleza bajomedieval que domina el municipio de Cañete la Real (Málaga) se corresponde con el ḥiṣn Qannῑṭ que citan las fuentes en periodo emiral. Del análisis documental y arqueológico que aquí presentamos, en contra de lo que se piensa, no cabe más que identificar el topónimo con el yacimiento altomedieval existente en el cerro de la Horca o de Sábora, situado en la periferia del municipio moderno, atendiendo especialmente a las selectas producciones cerámicas que observamos en superficie, piezas adecuadas al gusto y prestigio social tanto de los señores locales como de los representantes omeyas que se instalaron en la fortaleza. En el plano histórico, a modo de reflexión, nos adentramos en el debate suscitado sobre la caracterización social de los grupos tribales establecidos en Tākurunnā (región rondeña), cuya conducta no es equiparable a la mantenida por los Banū Jalῑʿ, destacada familia de clientes omeyas que adopta una posición asimilacionista desde el primer tercio del siglo VIII. En último término, ofrecemos una primera aproximación descriptiva sobre las defensas y fortalezas más inmediatas a ḥiṣn Qannῑṭ y recogemos evidencias arqueológicas de sus características constructivas.
Effects of Some Monetary Policy Targets on Inflation and Inflation Volatility: Evidence from Nigeria
Authors: C. G Amaefula
Published: June 2021

The persistent inflationary pressure despite monetary policy targets has become a phenomenon of interest among researchers. The study investigates the effects of monetary policy targets on inflation and its volatility in Nigeria using data spanning from 1985 to 2019. The ADF unit root test used confirmed that all the variables under study are integrated order zero in their level series. A Comparison of inflation volatility models (ARCH and GARCH models) with appropriate error distribution using AIC indicated that ARCH (1) is most appropriate. The results of least squares (LS) and maximum likelihood (ML) ARCH methods of estimation for the model specifications showed that measures of monetary policy targets such as narrow money supply (M1), broad money supply(M2), net domestic credit(NDC), net credit to government(NCG) and credit to private sector(CPS) have no significant effect on inflation and inflation volatility respectively except M2. However, M2 effect spurs inflation rather than curbing it. Hence, it becomes imperative for the government to make proactive policies targeted to reduce inflationary pressures so as to attain price stability in Nigeria’s economic space.

Published: June 2021

This study examines the distribution of dump sites within The Polytechnic, Ibadan, Nigeria. IKONOS Satellite imagery was acquired and processed for proper identification of the existing dump sites. Field data were acquired using Global Positioning System (Garmin GPS 72csx). Image and data processing as well as database creation was done using ArcGIS 10.5 (Arcmap 10.5). Legal and illegal dump sites were identified and mapped out and as well as the proximity of the dump sites to roads, residential areas and waterways in the study area were determined. Composite map and spatial analysis map queries were produced. From the result, it shows that eleven (11) legal dump sites and twenty four (24) illegal dump sites were within the study area. World standards on dump sites conformity were considered. From the result in the study area, it shows that there are more illegal dump sites than legal dump sites. Based on proximity of the dump sites to the roads, waterways and built up areas, many of the dump site were very close to buildings where they only not destroy the aesthetic value of the areas but also constitute breeding grounds for vectors like flies, rodents, mosquitoes, which transmit diseases like typhoid fever, malaria, cholera and laser fever which are part of the killer diseases in Nigeria and most of the African countries. Therefore, the study recommends that more legal dump sites should be created and monitored in the study area, most especially in the Northern parts the study area since the population there is high. Also, students as well as staff should be well educated on the risk associated with indiscriminate refuse disposal.

Determinants of corporate social disclosure in Saudi Arabia: The role of social values and IFRS convergence
Authors: AlShetwi Mohammed
Published: June 2021

This study investigates whether Corporate Social Disclosure (CSD) is affected by IFRS convergence and social value in a country that has strict societal norms (Saudi Arabia). Using a sample of 292 Saudi manufacturing and utilities firms listed on the Saudi Capital Market during the period of 2015-2019, the study finds that IFRS convergence is not related to the CSD of the Saudi manufacturing and utilities firms. On the other hand, social values (as modeled by adopting CSD as a strategic objective) are significantly related to CSD. These results provide evidence supporting the view that CSD is influenced by social values rather than the change in the corporate disclosure environment in countries that exhibit strong conformity to societal values, such as Saudi Arabia. Overall, the current study adds to an understanding of the factors that determine CSD outside the shareholder-stakeholder orientation model.

The effect of organizational culture on quality of accounting information: Mediating the role of accounting information system
Authors: Huynh Quang Linh
Published: June 2021

Organizational culture has been documented as a driving force of the acceptance of accounting information systems in business and accounting information quality; whereas accounting information quality as a causation of the acceptance of accounting information systems in business. The acceptance of accounting information systems in business could mediate the causal connection from organizational culture to accounting information quality. Nonetheless, nearly none of the projects has assessed the mediating role of the acceptance of accounting information systems in business, especially in Vietnam as a developing country. The current research tries to investigate the mediation of the acceptance of accounting information systems in business in the research model. The findings indicate that the acceptance of accounting information systems in business transmits part of the influence of organizational culture on accounting information quality. The current research could make some contributions to how executives ought to decide on organizational culture as well as on the acceptance of accounting information systems in business so that their organizational performance could be improved.
The effectiveness of the internal corporate governance mechanism and the ownership of the government and agencies
Authors: Aljaaidi Khaled Salmen
Published: June 2021

This paper examines the impact of the government and its agencies’ ownership on the effectiveness of one the main internal governance mechanisms, namely; board of directors, for a sample of 140 energy and petrochemical Saudi listed firms over 2012-2019. The Saudi Arabia provides an interesting context due to the domination of government-linked corporations’ ownership. This setting arranges for the impact of such ownership on the board of directors’ monitoring and advisory roles. The board of directors’ effectiveness is measured as an interaction term of the board size and meetings of the board of directors. The study finds that government-linked energy and petrochemical corporations’ ownerships are inversely related to the board of directors’ effectiveness. This result is sensitive to the measurement of the board of directors’ effectiveness as each variable consisting of the board of directors’ effectiveness was examined individually. The study also finds that government-linked corporations’ ownership had a strong negative impact on the board size. In contrast, the proposed model does not provide any evidence supporting the relationship of the government-linked corporations’ ownerships with board meetings. Overall, the evidence supports the substitution hypothesis on the relationship of government-linked corporations and board of directors’ effectiveness.

Published: June 2021

The objective of this research was to determine the effect of corruption on economic growth in Peru for the period 1998-2018. It was determined how economic growth was affected both in the short and long term by corruption. The corruption control index was used to measure corruption and the variation in gross domestic product (GDP) at constant prices was used to measure economic growth. To determine this effect, the hypothetical deductive method was used as a general method since we sought to corroborate a hypothesis and as a specific method, we used the Autoregressive Model of Distributed Lag (ARDL) since this model adapts well to small samples, likewise we had a non-experimental research design – longitudinal explanatory. Data were collected from the World Bank and the Ministry of Education (MINEDU) from 1998 to 2018. As a result of the econometric ARDL model, it was obtained that corruption had a negative effect on economic growth since an improvement of one percentage point in the corruption index would mean an improvement of 0.55 percentage points in economic growth. Therefore, it is concluded that the effect of corruption has a negative effect on economic growth as expected according to the reviewed antecedents.
Can financial literacy become an effective mediator for investment intention?
Authors: Tanuwijaya Kelvin , Setyawan Ignatius Roni
Published: June 2021

The lifestyle of Indonesian people who are very consumptive makes it difficult for people to invest. This can be shown in the number of capital market investors in Indonesia which is only 0.61% of the total population. The low level of financial literacy in Indonesia is one factor. Many people do not understand finance so they cannot manage finances properly. In this study, we look for 130 respondents who are college students to find out how financial socialization and financial experience influence on investment intention through financial literacy. The theory used in this research is theory of planned behavior and social learning theory. In this study, financial literacy can only mediate the financial experience of investment intention. The results of this study are in accordance with the theory of planned behavior in which one of the elements is perceived behavioral control with self-control factors originating from within, namely experience so that the financial experience is expected to generate interest in investing.

Published: June 2021

Anaphylaxis is a severe, potentially life threatening allergic reaction which occurs in adults and children. Prompt diagnosis and appropriate acute medical management will prevent fatal anaphylactic episodes. Anaphylactic reactions are IgE mediated responses to foreign antigens to which there has been previous exposure. The foreign antigens commonly implicated in anaphylaxis are foods (particularly nuts), drugs and venoms. Long term management should involve liaison with an immunologist/allergist to identify an underlying cause, provide education for further prevention and where possible offer immunotherapy.

Direct ophthalmoscopy is an essential part of the full systemic examination. However, the technique is challenging and time-consuming. In the acute medical setting therefore, it is advisable for the physician to identify the subgroup of patients in whom examination of the fundus is most likely to be helpful. Ophthalmoscopy should be performed where papilloedema is suspected, in those with an altered level of consciousness or other focal neurology, those with an unknown systemic disorder, and those complaining of visual disturbance.

Published: June 2021

A 52 year old patient, originally thought to have musculoskeletal chest pain was found to have features consistent with infective pleurisy on initial blood tests and chest x-ray, with a negative d-dimer indicating a low likelihood of pulmonary embolism. Two weeks later he represented with continued symptoms and investigations revealed extensive pulmonary emboli, which were thought to have developed after his initial presentation.

Published: June 2021

Myasthenia gravis was first described 300 years ago, but today is one of the most well characterised autoimmune diseases. Whilst its prognosis was previously grave, cholinergic and immunomodulatory therapy has greatly improved survival over the last two decades. Improved recognition of the condition and effective therapy has transformed this previously debilitating and often fatal condition into an eminently treatable and reversible condition.

Published: June 2021

Examination of the pupillary responses, being simple, reliable and highly reproducible can elicit one of the “hard” neurological signs. In this article we provide an overview of their assessment in the acute setting, along with some tips on low to get the best from your pen torch.
Acute Coronary Syndromes i
Authors:   University Hospital of Wales, Heath Park, Cardiff & Vale NHS Trust, Raybould A D , Groves P H ,   University Hospital of Wales, Heath Park, Cardiff & Vale NHS Trust
Published: June 2021

The acute coronary syndromes form a clinical spectrum, which ranges from unstable angina without myocardial injury, non-ST segment elevation and ST segment elevation myocardial infarction. All three conditions share a common pathophysiological basis. The management of acute ST segment elevation myocardial infarction however, is distinct from the other syndromes and therefore forms the basis of another article in this series. In this article we concentrate on the recognition and management of unstable angina and Non ST-segment elevation myocardial infarction (NSTEMI).
Sudden Headaches
Authors:   Royal United Hospital Combe Park Bath BA1 3NG, Giffin N J
Published: June 2021

Sudden severe headache is a cardinal feature of subarachnoid haemorrhage (SAH) and other potentially life threatening neurological conditions. Early diagnosis and management improves the outcome of SAH. In general practice, benign thunderclap headache vastly outnumbers SAH as a cause of sudden headache. Thunderclap headache is a diagnosis of exclusion and all patients admitted with a first presentation of a severe headache lasting more than one hour should be investigated with a CT and lumbar puncture. It must be borne in mind that these investigations may miss diagnoses such as venous sinus thrombosis and Magnetic Resonance Angiography (MRA) should be performed if clinical suspicion remains high.
The Emergency Management of Adult Bacterial Meningitis
Authors: Hartman Giles C , Gjini Ardiana , Heyderman Robert S ,   Department of Pathology & Microbiology, School of Medical Sciences, University of Bristol, University Walk, Bristol
Published: June 2021

Over the last decade, new protein-conjugate vaccines against Haemophilus influenzae type b (Hib) and Neisseria meningitidis serogroup C (MenC) have had a dramatic effect on the epidemiology of childhood meningitis in the United Kingdom. Amongst adults, bacterial meningitis remains an important cause of preventable morbidity and mortality. Clinicians need to remain vigilant for the possibility of this infection. The identification of the one patient with meningitis out of many with trivial viral infections remains a difficult task. Even once the diagnosis is made clinically, the subsequent investigation and management of the patient remains controversial, with strong opinions often influenced by one or two adverse experiences. Potential improvements in the way we identify and manage meningitis patients have been identified in recent years. This review will focus on those areas relevant to the emergency care specialist. Meningitis in the immunocompromised patient often has a different clinical and epidemiological pattern and is beyond the scope of this review.
Thyroid Emergencies part 1: Thyroid Storm
Authors:   North Hampshire Hospital Aldermaston Road Basingstoke, Herts, Turner Ben C
Published: June 2021

Thyroid storm is associated with multisystem decompensation and high mortality if untreated. Early clinical recognition and aggressive treatment in a high dependency setting are crucial to a successful outcome. A combination of high-dose antithyroid medication, β-blockade, iodine, steroids and careful haemodynamic management are the essential therapeutic elements, with the potential for a prompt recovery. The pathophysiology, causes and treatment of thyroid storm are reviewed.
Training in Acute Medicine in 2004

There is a school of thought that believes that if something is going right then the downturn is just around the corner! As work progressed to get Acute Medicine recognised as a sub speciality there were many occasions when it was felt that we could still stumble as we came to the final hurdle. Happily that did not occur and by July 2003 Acute Medicine was officially recognised as a new sub speciality within General Internal Medicine. Can we expect any further hurdles? It is often appropriate to recognise the challenges which occur and regard them as opportunities that have to be used for our advantage. Sometimes this is very difficult.

Acute Assessment Units (AAUs) have been developed to meet the demand for emergency care. Traditionally, AAUs have been an admission route to secondary care but the role is now evolving to assessment. AAUs are complex and have many interactions both in hospitals and the community. The effective functioning of an AAU requires excellent clinical leadership, appropriate facilities, timely access to diagnostics and input from the multi-disciplinary team. Increasingly, AAUs will have to develop services which are not dependent on using hospital beds. A variety of emergency medical presentations can, with the appropriate resources, be delivered in an out-patient setting.
