Sites of Transformation
Authors: Wilson Louise Ann
Published: February 2022

In this book practitioner and researcher Louise Ann Wilson examines the expanding field of socially engaged scenography and promotes the development of scenography as a distinctive type of applied art and performance practice that seeks tangible, therapeutic, and transformative real-world outcomes. It is what Christopher Baugh calls ‘scenography with purpose’.

Using case studies drawn from the body of site-specific walking-performances she has created in the UK since 2011, Wilson demonstrates how she uses scenography to emplace challenging, marginalizing or ‘missing’ life-events into rural landscapes – creating a site of transformation – in which participants can reflect upon, re-image and re-imagine their relationship to their circumstances. Her work has addressed terminal illness and bereavement, infertility and childlessness by circumstance, and (im)mobility and memory. These works have been created on mountains, in caves, along coastlines and over beaches. Each case-study is supported by evidential material demonstrating the effects and outcomes of the performance being discussed.

The book reveals Wilson’s creative methodology, her application of three distinct strands of transdisciplinary research into the site/landscape, the subject/life-event, and with the people/participants affected by it. She explains the 7 ‘scenographic’ principles she has developed, and which apply theories and aesthetics relating to land/scape art and walking and performance practices from Early Romanticism to the present day. They are underpinned by the concept of the feminine ‘material’ sublime, and informed by the attentive, autotopographic, therapeutic and highly scenographic use of walking and landscape found in the work of Dorothy Wordsworth and her female contemporaries. Case studies include Fissure (2011), Ghost Bird (2012), The Gathering (2014), Warnscale (2015), Mulliontide (2016), Dorothy Room (2018) and Women’s Walks to Remember: ‘With memory I was there’ (2018–2019).
Dante’s Divine Comedy in Early Renaissance England
Authors: Hughes Jonathan
Published: February 2022

Dante’s Divine Comedy in Early Renaissance England compares the intellectual, emotional, and religious world of Dante in 13th-century Florence with that of a group of English intellectuals gathered around Humphrey, Duke of Gloucester, uncle of the King, Henry VI.

Here, Jonathan Hughes establishes that there was a Renaissance in 15th-century England, encouraged by the discovery and translations of works of Greek philosophers and developments in science and medicine; and that vernacular writers in Gloucester’s circle, such as John Lydgate and Robert Hoccleve, were of fundamental importance in exploring the meaning of the self and man’s relationship with the natural world and the classical past. However, the appearance in 15th-century England of Dante’s ‘Commedia’, the most popular work of the Middle Ages, served to remind writers and readers of the cost of intellectual enquiry: the loss of faith in a harmonious and beautiful world; the redemptive power of the love of a woman; and the tangible presence of an afterlife.

Engagingly written and meticulously researched, this innovative study shines a new perspective on Dante scholarship as well as offering a unique anaylsis of intellectual thought and culture in 15th-century England.

To investigate the effect of the simultaneous administration of Homoeopathic low potencies (4 CH) of phosphocreatine and glycogen on the anaerobic work capacity of human thigh muscle.
Authors:   , Naude Wayne Stuart
Published: February 2022

The purpose of this study was to investigate the effect of the administration of homoeopathic dilutions of phosphocreatine and glycogen on the anaerobic work capacity of humanthigh muscle. It was hypothesized that there would be an increase in the anaerobic work capacity after one week, and that this effect would persist for a further four weeks. The experimentwas performed according to the protocol of a double - blind clinical trial. The subjects were male caucasians between 17 and 23 years of age, all in good health for the duration of the test period. Sixteen subjects took doses of Phosphocreatine 4 CH and Glycogen 4 CH three times daily for 7 days (the experimental group). Twenty one different subjects took a placebo preparation at a similar dosage. The placebo preparation was 20 % ethanol in water, making it impossible to distinguish it by taste from the experimental preparation. Tests were performed on the Akron isokinetic tester. TIrree tests were performed by each subject: an initial test, and follow - up tests on days 7 and 35. The tests were in the form of explosive flexion and extension of the leg, with a maximum displacement of 195 degrees per second, for 30 seconds. The accumulated work done in flexion and extension was calculated. The subjects were instructed to continue in their normal lifestyle for the duration of the test period. Statistical analysiswas carried out, using the Wilcoxon signed - rank test to test for intra - group variation, and the Mann - Whitney U test to test for inter - group variation. Intra - group analysis of the variance revealed statistically significant increases in work done in the first and second follow - up tests for both the experimental and placebo groups. Inter - group analysis revealed that the groups were not statistically different in any of the parameters tested. Because the anaerobic work capacity increased in both the experimental and placebo groups, we conclude that the preparation was not the cause of the increase. We speculate that the increase could be due to psychological factors, such as differingresponses to motivation, and familiarity with the procedure in the follow - up tests, and physiological factors such as meals eaten or missed before the tests were performed.
The effectiveness of manipulation combined with a cervical pillow compared to manipulation alone in the management of mechanical neck pain
Authors:   , Allwood Tracey Elaine
Published: February 2022

Neck pain is a common condition that has become a serious health concern. Since there is controversy regarding the most effective management of this condition, further research needs to be executed. The purpose of this investigation was to compare manipulation combined with a cervical pillow to manipulation alone in the management of mechanical neck pain. The rationale behind this, was that manipulation is one of the most common treatments for spinal conditions and has shown significant results in alleviating mechanical neck pain. Cervical pillows have been investigated by various researchers. They have concluded that cervical pillows are effective in treating mechanical neck pain. Thus, using the pillow as an adjunct to manipulation should attain superior results to manipulation alone. This study consisted of 40 patients who were randomly divided into 2 equal groups. The average age of the patients was 34 years old and the average duration of neck pain was pain of greater than 6 months. The patients received 6 treatments over a 4 week period. Group1 were manipulated and given a cervical pillow to sleep on, while group 2 received manipulation alone.
The homoeopathic treatment of menopausal symptoms with Folliculinum 30CH
Authors:   , Domleo Sinden Jane
Published: February 2022

This double-blind placebo-controlled study investigated the efficacy of Folliculinum 30CH in the treatment of menopausal symptoms in terms of the patients' perception of the treatment. Menopause is a phase in every woman's life marking the end of her reproductive years. Natural menopause occurs at an average age of 50 to 51 years when ovarian response to follicle stimulating hormone and luteinising hormone decreases resulting in fewer ovulations and a decrease in circulating oestrogen and progesterone levels. This change in hormone levels can cause symptoms such as hot flushes, night sweats, mood swings, insomnia and loss of sex drive. Currently the most widely used treatment for these symptoms is hormone replacement therapy. This form of treatment is effective for many women, but there are many risks and side effects associated with its use. It is for this reason that Folliculinum 30CH was investigated as a treatment for menopausal symptoms. A total of 30 female patients who were going through natural menopause and currently' experiencing menopausal symptoms took part in the study. An independent person randomly assigned 15 patients to the treatment group and 15 to the placebo group. Each participant consulted with the researcher every 3 weeks for a total of 4 consultations. At the first consultation each patient was given a number 2 vial containing either Folliculinum (treatment group) or unmedicated granules (placebo group) and were instructed to take a quarter of a cap of the granules once a week follo~ed by a period of 3 weeks in which no medication was taken. At each consultation the participants were required to complete the Psychological General Well- Being Index and Greene Climacteric Scale questionnaires. Each patient was given a Hot Flush Record Chart at each consultation. The number of hot flushes were recorded by the participant every day and tallied at the subsequent consultation. The data was analysed using the SPSS programme for Windows. The Mann-Whitney unpaired two-tailed test showed that there was no significant difference between the treatment and placebo groups. Friedman's Test showed that there was a significant difference with regards to the Hot Flush Record Chart (p = 0.023) and the GCS (psychological) (p = 0.031). The Dunn procedure was then performed to determine which of the consultations were significantly different.

Cloud-probability-based estimation of black-sky surface albedo from AVHRR data
Authors: Manninen Terhikki , Jääskeläinen Emmihenna , Siljamo Niilo , Riihelä Aku , Karlsson Karl-Göran
Published: February 2022

Abstract. This paper describes a new method for cloud-correcting
observations of black-sky surface albedo derived using the Advanced Very
High Resolution Radiometer (AVHRR). Cloud cover constitutes a major
challenge for surface albedo estimation using AVHRR data for all
possible conditions of cloud fraction and cloud type with any land cover type
and solar zenith angle. This study shows how the new cloud probability
(CP) data to be provided as part of edition A3 of the CLARA (CM SAF cLoud,
Albedo and surface Radiation dataset from AVHRR data) record from the
Satellite Application Facility on Climate Monitoring (CM SAF) project of EUMETSAT
can be used instead of traditional binary cloud masking to derive cloud-free
monthly mean surface albedo estimates. Cloudy broadband albedo distributions
were simulated first for theoretical cloud distributions and then using
global cloud probability (CP) data for 1 month. A weighted mean approach
based on the CP values was shown to produce very-high-accuracy black-sky
surface albedo estimates for simulated data. The 90 % quantile for the
error was 1.1 % (in absolute albedo percentage) and that for the relative error
was 2.2 %. AVHRR-based and in situ albedo distributions were in line with each
other and the monthly mean values were also consistent. Comparison with
binary cloud masking indicated that the developed method improves cloud
contamination removal.
Three-way calibration checks using ground-based, ship-based, and spaceborne radars

Published: February 2022

Abstract. This study uses ship-based weather radar observations collected from research vessel Investigator to evaluate the Australian weather radar network calibration monitoring technique that uses spaceborne radar observations from the NASA Global Precipitation Mission (GPM). Quantitative operational applications such as rainfall and hail nowcasting require a calibration accuracy of ±1 dB for radars of the Australian network covering capital cities. Seven ground-based radars along the western coast of Australia and the ship-based OceanPOL radar are first calibrated independently using GPM radar overpasses over a 3-month period. The calibration difference between the OceanPOL radar (used as a moving reference for the second step of the study) and each of the seven operational radars is then estimated using collocated, gridded, radar
observations to quantify the accuracy of the GPM technique. For all seven
radars the calibration difference with the ship radar lies within ±0.5 dB, therefore fulfilling the 1 dB requirement. This result validates the concept of using the GPM spaceborne radar observations to calibrate national weather radar networks (provided that the spaceborne radar maintains a high calibration accuracy). The analysis of the day-to-day and hourly variability of calibration differences between the OceanPOL and Darwin (Berrimah) radars also demonstrates that quantitative comparisons of gridded radar observations can accurately track daily and hourly calibration differences between pairs of operational radars with overlapping coverage (daily and hourly standard deviations of ∼ 0.3 and ∼ 1 dB, respectively).

Abstract. The current improvements in aerosol mass spectrometers in resolution and sensitivity, and the analytical tools for mass spectra deconvolution, have enabled the in depth analysis of organic aerosol (OA) properties. Although OA constitutes a major fraction of ambient aerosol, the overall aerosol properties are determined by the mixing characteristics of both organic and inorganic contents of ambient aerosol. In the present study, the mass spectra of both organic and inorganic aerosol were obtained by a time–of–flight aerosol mass spectrometer (ToF-ACSM) and further merged into one input matrix for Positive Matrix Factorization (PMF) analysis. The scope of this work was to assess the sources of organic aerosol and total non–refractory species in the suburbs of Athens, check their temporal variation and the interactions between organic and inorganic species, after reaching environmentally reasonable solutions for both matrices. The results revealed five factors in the case of the organic aerosol matrix. Three of them were primary OA factors: hydrocarbon–like (HOA), cooking related (COA) and biomass burning (BBOA), and the remaining two were secondary, less and more oxidized oxygenated organic aerosol (LO-OOA and MO-OOA, respectively). The relative contributions of these factors were HOA 15 %, COA 18 %, BBOA 9 %, MO-OOA 34 % and LO-OOA 24 % (yearly averaged). In the case of the combined aerosol matrix, two additional factors were identified that were mainly composed of ammonium sulfate (83.5 %) and ammonium nitrate (73 %). Moreover, the two secondary factors with both organics and inorganics were named as more (MOA) and less oxidized aerosols (LOA). The relative contributions on a yearly average of these factors were HOA 6 %, COA 9 %, BBOA 6%, Ammonium Nitrate 4 %, Ammonium Sulfate 28 %, MOA 23 % and LOA 24 %. The results showed a variation in secondary aerosols composition of organics and inorganics, mainly in less oxidized aerosol (LOA). This factor was composed primarily of organics during winter (80 %), while both organics and inorganics contributed equally to this factor in spring and summer; and in early autumn this factor presented more sulfate (70 %) than organics. This work presents a new methodology on ACSM data analysis, provides insights on the sources of the non–refractory species of ambient aerosols and using innovative tools for applying PMF (Rolling window) enables the study of the temporal variation of these sources and also the variability of their composition.
A new Greenland digital elevation model derived from ICESat-2 during 2018–2019
Authors: Fan Yubin , Ke Chang-Qing , Shen Xiaoyi
Published: February 2022

Abstract. Greenland digital elevation models (DEMs) are indispensable to
fieldwork, ice velocity calculations, and mass change estimations. Previous
DEMs have provided reasonable estimations for all of Greenland, but the
time span of applied source data may lead to mass change estimation bias. To
provide a DEM with a specific time stamp, we applied approximately
5.8×108 ICESat-2 observations from November 2018 to November 2019 to generate a new DEM, including the ice sheet and glaciers in
peripheral Greenland. A spatiotemporal model fit process was performed at
500 m, 1 km, 2 km, and 5 km grid cells separately, and the final DEM was posted at
the modal resolution of 500 m. A total of 98 % of the grids were obtained
by the model fit, and the remaining DEM gaps were estimated via the ordinary
Kriging interpolation method. Compared with IceBridge mission data acquired
by the Airborne Topographic Mapper (ATM) lidar system, the ICESat-2 DEM was
estimated to have a maximum median difference of −0.48 m. The performance of
the grids obtained by model fit and interpolation was similar, both of which
agreed well with the IceBridge data. DEM uncertainty rises in regions of low
latitude and high slope or roughness. Furthermore, the ICESat-2 DEM showed
significant accuracy improvements compared with other altimeter-derived
DEMs, and the accuracy was comparable to those derived from
stereophotogrammetry and interferometry. Overall, the ICESat-2 DEM showed
excellent accuracy stability under various topographic conditions, which can
provide a specific time-stamped DEM with high accuracy that will be useful
to study Greenland elevation and mass balance changes. The Greenland DEM and
its uncertainty are available at

Recovery of sparse urban greenhouse gas emissions
Authors: Zanger Benjamin , Chen Jia , Sun Man , Dietrich Florian
Published: February 2022

Abstract. To localize and quantify greenhouse gas emissions from cities, gas concentrations are typically measured at a small number of sites and then linked to emission fluxes using atmospheric transport models. Solving this inverse problem is challenging because the system of equations is usually underdetermined. A common top-down approach to solving this problem is Bayesian inversion that uses a given Gaussian prior emission field. However, such an approach has drawbacks when the assumed spatial emission distribution is incorrect. In our work, we investigate sparse reconstruction (SR), an alternative reconstruction method that does not require a prior emission field, but only the assumption that the emission field is sparse. We show that this assumption is mostly true for the cities we investigated and that the use of the discrete wavelet transform helps to make the urban emission field even more sparse. To evaluate the performance of SR, we created concentration data by applying an atmospheric forward transport model to CO2 emission inventories of several major European cities. We used SR to locate and quantify the emission sources by applying compressed sensing theory and compared the results to regularized least squares (LS) methods. Our results show that SR requires fewer measurements than LS methods and that SR provides better localization and quantification of unknown emitters.
Remote sensing-aided rainfall–runoff modeling in the tropics of Costa Rica

Published: February 2022

Abstract. Streamflow simulation across the tropics is limited by the lack of data to calibrate and validate large-scale hydrological models. Here, we applied the process-based, conceptual HYPE (Hydrological Predictions for the Environment) model to quantitatively assess Costa Rica's water resources at a national scale. Data scarcity was compensated for by using adjusted global topography and remotely sensed climate products to force, calibrate, and independently evaluate the model. We used a global temperature product and bias-corrected precipitation from Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS) as model forcings. Daily streamflow from 13 gauges for the period 1990–2003 and monthly Moderate Resolution Imaging Spectroradiometer (MODIS) potential evapotranspiration (PET) and actual evapotranspiration (AET) for the period 2000–2014 were used to calibrate and evaluate the model applying four different model configurations (M1, M2, M3, M4). The calibration consisted of step-wise parameter constraints preserving the best parameter sets from previous simulations in an attempt to balance the variable data availability and time periods. The model configurations were independently evaluated using hydrological signatures such as the baseflow index, runoff coefficient, and aridity index, among others. Results suggested that a two-step calibration using monthly and daily streamflow (M2) was a better option than calibrating only with daily streamflow (M1), with similar mean Kling–Gupta efficiency (KGE ∼ 0.53) for daily streamflow time series, but with improvements to reproduce the flow duration curves, with a median root mean squared error (RMSE) of 0.42 for M2 and a median RMSE of 1.15 for M1. Additionally, including AET (M3 and M4) in the calibration statistically improved the simulated water balance and better matched hydrological signatures, with a mean KGE of 0.49 for KGE in M3–M4, in comparison to M1–M2 with mean KGE < 0.3. Furthermore, Kruskal–Wallis and Mann–Whitney statistical tests support a similar model performance for M3 and M4, suggesting that monthly PET-AET and daily streamflow (M3) represents an appropriate calibration sequence for regional modeling. Such a large-scale hydrological model has the potential to be used operationally across the humid tropics informing decision-making at relatively high spatial and temporal resolution.
Past and future trends in fire weather for the UK

Abstract. Past and future trends in the frequency of high-danger fire weather conditions have been analysed for the UK. An analysis of satellite-derived
burned area data from the last 18 years has identified the seasonal cycle with a peak in spring and a secondary peak in summer, a high level of
interannual variability, and a lack of a significant trend despite some large events occurring in the last few years. These results were confirmed
with a longer series of fire weather indices back to 1979. The Initial Spread Index (ISI) has been used for spring, as this reflects the moisture of
fine fuel surface vegetation, whereas conditions conducive to summer wildfires are hot, dry weather reflected in the moisture of deeper organic
layers which is encompassed in the Fire Weather Index (FWI). Future projections are assessed using an ensemble of regional climate models from the UK Climate Projections, combining variables to derive the fire
weather indices. The results show a large increase in hazardous fire weather conditions in summer. At 2 ∘C global warming relative
to 1850–1900, the frequency of days with “very high” fire danger is projected to double compared to the recent historical period. This frequency
increases by a factor of 5 at 4 ∘C of global warming. Smaller increases are projected for spring, with a 150 % increase for England at
2 ∘C of global warming and a doubling at 4 ∘C. A particularly large projected increase for late summer and early
autumn suggests a possible extension of the wildfire season, depending on fuel availability. These results suggest that wildfire can be considered an “emergent risk” for the UK, as past events have not had widespread major impacts, but this
could change in future, with adaptation actions being required to manage the future risk. The large increase in risk between the
2 and 4 ∘C levels of global warming highlights the importance of global efforts to keep warming below
2 ∘C.
Reflection tomography by depth warping: a case study across the Java trench
Authors: Xia Yueyang , Klaeschen Dirk , Kopp Heidrun , Schnabel Michael
Published: February 2022

Abstract. Accurate subsurface velocity models are crucial for
geological interpretations based on seismic depth images. Seismic reflection
tomography is an effective iterative method to update and refine a
preliminary velocity model for depth imaging. Based on residual move-out
analysis of reflectors in common image point gathers, an update of the
velocity is estimated by a ray-based tomography. To stabilize the
tomography, several preconditioning strategies exist. Most critical is the
estimation of the depth error to account for the residual move-out of the
reflector in the common image point gathers. Because the depth errors for
many closely spaced image gathers must be picked, manual picking is
extremely time-consuming, human biased, and not reproducible. Data-driven
picking algorithms based on coherence or semblance analysis are widely used
for hyperbolic or linear events. However, for complex-shaped depth events,
purely data-driven picking is difficult. To overcome this, the warping method
named non-rigid matching is used to estimate a depth error displacement
field. Warping is used, for example, to merge photographic images or to match two
seismic images from time-lapse data. By matching a common image point gather
against its duplicate that has been shifted by one offset position, a
locally smooth-shaped displacement field is calculated for each data sample
by gather matching. Depending on the complexity of the subsurface, sample
tracking through the displacement field along predefined horizons or on a
simple regular grid yields discrete depth error values for the tomography.
The application to a multi-channel seismic line across the Sunda subduction
zone offshore Lombok island, Indonesia, illustrates the approach and
documents the advantages of the method to estimate a detailed velocity
structure in a complex tectonic regime. By incorporating the warping scheme
into the reflection tomography, we demonstrate an increase in the velocity
resolution and precision by improving the data-driven accuracy of depth
error picks with arbitrary shapes. This approach offers the possibility to
use the full capacities of tomography and further leads to more accurate
interpretations of complex geological structures.
Accelerated Mobilization of Organic Carbon from Retrogressive Thaw Slumps on the Northern Taymyr Peninsula

Published: February 2022

Abstract. With climate change, Arctic hillslopes above ice-rich permafrost are vulnerable to enhanced mass wasting and organic carbon mobilization. In this study we use TanDEM-X-derived digital elevation models to document an approximately 43-fold increase in thaw slumping and concomitant 28-fold increase in carbon mobilization on the Taymyr Peninsula from 2010 to 2021. The available observations allowed us to compare two time-periods, from 2010/11 to 2016/17 and from 2017/18 to 2020/21, and contrast Retrogressive Thaw Slump (RTS) activity between these periods. We find that all quantities describing RTS activity increased in the observed period. The total volumetric change per year increased from about 0.17 · 106 m3 yr−1 to 7.4 · 106 m3 yr−1, a 43-fold increase. The observed surge in RTS activity is mainly driven by the initiation of new RTS, indicated by the 17-fold increase in active RTS numbers from 82 to 1404 and the relative low average volumetric change rate per RTS increase of 2.3. In annual Sentinel-2 imagery, the number of detected RTSs in a subregion increased 10-fold in 2020. This coincides with a severe heatwave that occurred in northern Siberia in 2020. The area-to-volume scaling of the RTSs varied only slightly over time, despite the 2020 heatwave, indicating a robustness of the relationship to such an event. To estimate the slump-mobilized organic carbon, we intersected the elevation changes with a soil organic carbon (SOC) map, with contrasting assumptions about the deep carbon pool and massive ice content. We estimated that the SOC mobilization rate increase 28-fold. The normalization of the SOC mobilization rate to our study region yields values of 11 gC yr−1 m−2 with a confidence interval of 5 to 38 gC yr−1 m−2. Comparison to an independent estimate of the Net Ecosystem Exchange of 4.1 ± 13.0 gC yr−1 m−2 illustrates the importance of RTS activity to the carbon cycle. These results underscore that mass wasting is an important but commonly neglected component of the Arctic carbon cycle, and particularly sensitive to extreme events.

MENYEMBAH TUHAN: SUATU STUDI EXEGETIS MAZMUR 100
Authors: Rame Gustaf R.
Published: February 2022

Mazmur 100 dikategorikan dalam jenis mazmur korban ucapan syukur yang terdiri dari dua bait yakni: bait pertama ayat 1-3, dan bait kedua ayat 4-5 masing-masing bait terdiri dari dua undangan dan alasan yang kuat mengapa harus menyembah TUHAN. Karena hubungan kedua bait sangat erat, maka mazmur ini sering dinyanyikan dengan berbalas-balasan dalam suatu jemaah atau sebagai nyanyian perarakan masuk ke dalam bait suci. Tetapi juga sebagai pengakuan iman kepada Allah sebagai Raja yang harus dilayani dan dimuliakan. Pesan utama dari Mazmur 100 adalah bahwa keselamatan tidak lagi dikhususkan kepada Israel saja melainkan keselamatan itu adalah bersifat universal, dimana tidak ada lagi diskriminasi dan pengurangan peran dari pihak lain untuk memuji dan menyembah TUHAN terhadap orang-orang dari segala bangsa di dunia yang telah ditebus TUHAN. Dengan demikian di dalam Mazmur 100 ini, Israel melihat hubungan TUHAN dengan bangsa-bangsa secara baru dan karena itu Israel juga harus memperbaharui pula. Karena hanya TUHAN-lah Allah dan tidak ada yang lain, maka hanya ada satu umat dan satu ibadah.
