Smart Tools for Tracing Organizational Competitive Behavior on Fast Decision Making
Authors: Afanador Nicolas , Bonilla Ricardo , Ocampo H. Jackson
Published: March 2022

Competitiveness is essential for an organization's success in both the public and private sectors. Using three well-known mathematical methodologies, this work has centered its analysis on factors that affect primarily organizational competitiveness viewed through three different scales (global, local, and businesses). Using these methods, researchers and decision-makers gain insight to perform a qualitative analysis over key metrics of each level looking for improvements in business competitive performance and elucidate the importance of intangible assets like strategy. The authors identified that although each tool can only let us know some aspects about system agents, after combining the three tools as a toolbox, it might be used in volatile and rapidly evolving settings when strategic approaches concentrate on accurate resource allocation that demands a lot of time.
Translating in Turbulent Times

Published: March 2022

The language service industry was deeply impacted by the COVID-19 pandemic. The turbulent times faced because of COVID-19 changed the way LSPs made decisions and delivered services to their customers. LSPs had to react by adapting themselves to the unexpected new market game. This study scrutinizes what the COVID-19 meant for the LSPs based in Colombia and Spain, and how they were tackled from those two different markets. Colombia, a developing country with an industry almost exclusively made up of independent freelance translators and interpreters, faced the crisis both distressingly and smartly. Spain, a developed country with a stronger language industry, coped with the COVID-19-induced economic calamity in a quite analogous fashion. In both cases, uncertainty led LSPs to make decisions, clarify their visions, and make a clear commitment to becoming sustainable in the global market. An in-depth analysis of how those two industries behaved might be useful to draw important conclusions on how a crisis can become an opportunity if properly managed.

Published: March 2022

Hand gesture recognition (HGR) is a natural kind of human-machine interaction that has been used in a variety of settings. In this chapter, the authors address work in the field of HGR applications in industrial robots, with an emphasis on processing stages and approaches in gesture-based human-robot interaction (HRI), which may be beneficial to other researchers. They examine several similar research in the field of HGR that use a variety of techniques, including sensor-based and vision-based approaches. They discovered that the 3D vision-based HGR technique is a hard but interesting study field after comparing the two methodologies. Hand gesture recognition has a major application for disabled peoples. The person who is not able to speak can use these kinds of systems to control the devices or various applications in his/her machine. This technology also has vast potential in the gaming industry. The gaming industry has already adapted this technique.

Effect of adding midazolam to intrathecal bupivacaine in children undergoing lower abdominal surgeries: A randomised controlled trial
Authors: Shama Ahmed A. , Ng Ka Ting , Shahen Moustafa M. , Abosamak Mohammed F.
Published: March 2022

Background and Aims:

Avoidance of general anaesthesia for short-duration surgeries is a prerequisite, especially for children. Spinal anaesthesia is established as an appropriate anaesthetic procedure for this target. Midazolam has been proven to be safe for children as premedication. This study aimed to evaluate the effects of adding midazolam to intrathecal bupivacaine on intraoperative quality, duration of spinal anaesthesia and postoperative (PO) analgesia for children undergoing lower abdominal surgeries.

Methods:

A prospective, comparative interventional study included 120 paediatric patients who were randomly divided into two groups that received intrathecal bupivacaine plus normal saline (B/S) or intrathecal bupivacaine plus midazolam (B/M). The efficacy of PO analgesia was assessed using the observational pain–discomfort scale (OPS). Duration of PO analgesia was measured, and recovery of motor block was assessed every 30 min till the Bromage scale reached 0. The level of PO sedation was assessed using the modified Wilson Sedation Score (WSS). Results were analysed using the one-way analysis of variance (ANOVA) test, Mann–Whitney test and Chi-square test.

Results:

Onset of sensory and motor blocks was significantly faster, and the frequency of patients having Bromage score of 3 within ≤10 min was significantly higher in group B/M than group B/S. Durations till sensory and motor recovery were significantly longer, the number of requests for PO analgesia was significantly lower and the mean of WSS was significantly higher at 30 and 120 min in group B/M than group B/S.

Conclusion:

Intrathecal bupivacaine–midazolam combination significantly prolonged the duration of spinal anaesthesia and provided prolonged PO analgesia.

Published: March 2022

Prune Belly syndrome (PBS) is a triad of absence of abdominal muscles, urinary tract malformations, and undescended testes. Due to partial or complete lack of abdominal muscles and flat diaphragm, there could be difficulty in breathing and effective coughing. It can also be associated with chest wall deformities which can cause increased incidence of respiratory infections and lead to complications in the peri and postoperative period. Here, we have discussed about the anesthetic challenges in 1-month-old baby diagnosed with PBS who was posted for cystoscopy.
Evaluation of Four Biomarkers in Patients Chronically Infected with Trypanosoma cruzi and Their Relationship with Disease Progression
Authors: de Oliveira Dayse Elisabeth Campos , do Nascimento Tavares Suelene Brito , de Oliveira Enio Chaves , Luquetti Alejandro O.
Published: March 2022

This study evaluated four biomarkers of inflammation or fibrosis as progression indicators for heart disease in patients with Chagas disease. We compared values of these markers at the time of the first sample collection of blood (first time point) and at the time of the last collection of blood (second time point) for 103 individuals positive for Trypanosoma cruzi antibodies. They were split into two clinical groups: 52 individuals with the indeterminate form of the disease at the first time point and 51 controls that already had either cardiac involvement (N = 25) or megaviscera (megaesophagus and/or megacolon; N = 26) at that time. All individuals had an electrocardiogram performed both at the first and second time point (mean time between time points: 11 years). All samples were blind tested for galectin-3, brain natriuretic peptide (NT-proBNP), lysyl oxidase-like protein 2 (LOXL2), and troponin. Differences in concentrations between samples were analyzed using the months between samples as the covariate. This analysis showed that values for all markers, except troponin biomarker had a significative increase at the second time point for the 91 patients without progression. A similar result was obtained for NT-proBNP and LOXL2 with sera from 12 patients that progressed with cardiac disease. The single marker that showed a significative difference between groups (P = 0.01) was galectin-3. We concluded that galectin-3 was the only marker with a prognostic value in relation to the progression or worsening of heart disease in patients with Chagas disease.
Catalytic hydrogenation of cardanol derived bifunctional monomers for polymerization with diesters
Authors: Mgaya James E.
Published: March 2022

ABSTRACT. Cardanol extracted from cashew nut shell liquid (agro-waste) was used to synthesize a bifunctional monomer; methyl 16-(3-hydroxyphenyl)hexadecanoate using DTBPMB modified palladium catalyst. Hydrogenation of this monomer using a Ru(acac)3/triphos/MSA catalytic system in aqueous dioxane and ammonia solution gave 3-(16-hydroxyhexadecyl)phenol (75% yield) and 3-(16-aminohexadecyl)phenol (37% yield) respectively. Polymerization of 3-(16-aminohexadecyl)phenol and 3-(16-hydroxyhexadecyl)phenol with dimethyl nonadecanedioate (a di-ester obtained from methoxycarbonylation of methyl oleate) resulted into oligomers consisting of up to nine condensed monomer units (in the volatile fraction) as was revealed by MALDI-TOF MS.

Roles of Heterogeneous Habitat for Conservation of Nymphalidae in Sarawak (East Malaysia)
Authors: S. G. Christharina , Abang Fatimah
Published: March 2022

Species diversity characterises an area or a targeted habitat and provides information on the species assemblages, which is a primary reflection of habitat diversity. It incorporates both species richness and abundance and may rely on factors, such as host-plant availability and food resources. Kubah National Park is a lowland mixed dipterocarp forest, and uniquely offers various vegetation types, which includes heath and submontane forests. In the present study, four contrasting forest habitats were selected along forest trails, namely, primary forests, secondary forests, heath forests and forest edges. Forty baited traps were used within a six-months of sampling period. The highest abundance was recorded at the heath forest while the least was at the secondary forest. However, there was no significant difference in terms of species abundance between forest habitats for subfamilies, as well as for the 15 most abundant nymphalid species sampled, except for Mycalesis mnasicles. This satyrine was regarded as being able to differentiate habitat, apart from sensitive to canopy openings. Secondary forest provides a heterogeneous habitat for nymphalids, and thus highest diversity was observed here. This study implies that habitat association of the family is crucial, as it will provide information for both species inventory as well as the fluctuation patterns of the nymphalids diversity. Similar study is suggested to be carried out in the future, which incorporates more than one habitat types and in a more extensive period.
Bearings-only Tracking Based on Distributed Multisensor Pseudolinear Kalman Filter
Authors: Zhang Jungen , Yang Shanglin
Published: March 2022

For bearings-only tracking (BOT), there are mainly two problems of nonlinear filtering and poor range observability. In the paper, a new distributed multisensor pseudolinear Kalman filter (PLKF) algorithm is proposed. The sensors use an instrumental vector PLKF (IV-PLKF) to process the measurements of the target independently, which can tackle the bias arising from the correlation between the measurement vector and pseudolinear noise by the bias compensation PLKF (BC-PLKF). The IV-PLKF embeds the recursive instrumental vector estimation method into the BC-PLKF, uses it to construct the instrumental vector, and applies the method of selective angle measurement to modify the local target state estimation and covariance. In the fusion center, the target state can be estimated by using the multisensor optimal information fusion criterion. Then the Cramer-Rao lower bound (CRLB) of multisensor BOT is derived. Simulation results show the effectiveness of the algorithm.

Authors: ÖZDEMİR Suzi , ŞİMŞEK Ayşegül
Published: March 2022

Menstrual bleeding and menstruation process is a physiological process that a woman experiences as monthly periods throughout her life as of the pubertal period, and it is seen as a taboo in many societies and is not talked about. In our study, we aimed to compile the attitudes and practices towards menstrual bleeding from past to present. While menstrual bleeding was considered sacred in some cultures in past cultures; in some, it has been a topic that is ashamed and cannot be talked about. In present days, due to the cultural taboos against menstruation, there is a lack of information about these issues and this affects reproductive health negatively. Menstrual hygiene information and education should be organized to eliminate incomplete and wrong menstrual practices, and this education should constitute an important part of health education.
RECURRENT FIBROUS DYSPLASIA ON RADIUS TREATED WITH VASCULARIZED FIBULAR GRAFT: A CASE REPORT
Authors: Andriandi Mr. , Moesbar Nazar , Tanudin Rudy
Published: March 2022

Introduction: Fibrous Dysplasia is a benign intramedullary fibro-osseous lesion that are reported to represent approximately 5%-7% of benign bone tumor. Treatment of fibrous dysplasia include bisphosphonates therapy and surgical procedures. Case Report: A 9-year-old girl presented with a mass on her left forearm 2 years ago. Primary resection by curettage was performed and patient did not and one year after the surgery, the mass recurred and patient complaint about lump and deformity on her left forearm. A limb salvage surgery by intercalary resection was performed to remove the tumor and the defect was filled with vascularized fibular graft from the right leg. Seven- month follow up show no sign of recurrence and patient underwent surgery to remove the implant. Discussion: Fibrous dysplasia represents a dysplastic disorder of bone characterized by solitary or multifocal polyostotic intramedullary lesion composed of proliferation of fibroblastic spindle cells. Treatment of fibrous dysplasia include conservative treatment and surgical procedures may be required for correction of deformity, prevention of pathologic fracture and/or eradication of symptomatic lesion. The free vascularized fibular graft is particularly suited for reconstruction of large forearm defects because the fibula matches the radius and ulna in size and shape with studies that shown healing rate of 89%. Conclusion: Fibrous Dysplasia is a benign intramedullary fibro-osseous lesion that are reported to represent approximately 5%-7% of benign bone tumor. The most common clinical symptom is swelling or deformity of the affected site. Treatment of fibrous dysplasia using vascularized fibular graft may be an effective option.

Published: March 2022

In classical graph theory, set of vertices in which every edge is incident to at least one of the vertex is called a vertex covering set and the problems of vertex covering (V C) are known as V C problems. The classical graphs do not reflflect the impact of vertex on the edge and such impact is reflflected in fuzzy incidence graphs (F IGs). We used optimization technique in a trade using clique covering (CC) in fuzzy incidence graphs (F IGs). This article includes, some basic defifinitions such as strength of clique(SC), strength of path (SP), strength of minimum clique (SMC), acceptable strength of path (ASP) and clique (ASC), robust number (RN), minimum covering number of the clique (MCNC), close measure CM, some examples and theorems in F IGs, new strategy of optimization to characterize and solve facility points problems by adopting the CC application of F IGs for a business alliance to get maximum total achievement by reducing the transportation cost. This procedure will be helpful to develop sustainable economic developmental goal of the world. Some already existing theorems in fuzzy graphs (F Gs) are also checked in F IGs. A mathematical model is defifined and a real life problem from a trade is solved keeping the fuzziness of the objects related to fuzzy incidence graph.

A pedagogia social numa perspectiva discursiva
Authors: Bernardino Sirino Marcio
Published: March 2022

Em tempos ditos ‘normais’, muitos estudos e reflexões vão sendo produzidos acerca do campo, em construção, da Pedagogia Social. Em tempos significados como ‘pandêmicos’, eis que as produções vão se ressignificando e se adequando à necessidade de afastamento social e uso das novas tecnologias, por meio da atribuição de novos sentidos por parte dos diferentes educadores, estudantes e pesquisadores que fazem, do campo do saber da Pedagogia Social, sua ‘morada’ acadêmica. Neste contexto, este artigo foi produzido a partir de uma investigação realizada com os participantes do Coletivo de Leituras e Investigações em Pedagogia Social (CLIPS), da Universidade Castelo Branco (UCB), a fim de identificar quais sentidos estão sendo articulados no processo de hegemonização do nome Pedagogia Social. Para esta finalidade, foi utilizada como ferramenta de coleta dos dados o aplicativo Mentimeter e, como referencial teórico-analítico, a Teoria do Discurso. Como resultado deste exercício, foi possível construir a ideia de Pedagogia Social como um significante vazio, repleto de sentidos em disputa no cenário socioeducacional brasileiro.
Para uma filosofia desde o Brasil
Authors: Aragão Diego
Published: March 2022

Pensar a possibilidade de uma Filosofia Brasileira ou construída desde o Brasil pode se mostrar uma tarefa complexa, capaz de levantar questionamentos acerca não só da própria definição do que seja filosófico, como também problematizar os limites da Filosofia. A relevância de investigar tal possibilidade reside no necessário desvestir-se colonial que vigora na prática filosófica universitária e no apontar novos caminhos filosóficos radicados no lugar e no tempo do filósofo. A metodologia da investigação realizada é a de revisão bibliográfica assentada nos estudos decoloniais desenvolvidos pelo autor. Pelas problematizações realizadas, notou-se a necessidade de construção de uma Filosofia desde o Brasil, desatrelada de nacionalismos e de identidades filosóficas vinculadas ao legado moderno eurocentrado. A interlocução com a Literatura, bem como com outras Artes, pode possibilitar o vislumbre de caminhos que expandem os limites do exercício filosófico e, assim permitem um pensar de outra forma e situado espaciotemporal nas problemáticas dos “de baixo”.

Measurement of Software Development Effort Estimation Bias: Avoiding Biased Measures of Estimation Bias
Authors: Jørgensen Magne
Published: March 2022

In this paper, we propose improvements in how estimation bias, e.g., the tendency towards under-estimating the effort, is measured. The proposed approach emphasizes the need to know what the estimates are meant to represent, i.e., the type of estimate we evaluate and the need for a match between the type of estimate given and the bias measure used. We show that even perfect estimates of the mean effort will not lead to an expectation of zero estimation bias when applying the frequently used bias measure: (actual effort – estimated effort)/actual effort. This measure will instead reward under-estimates of the mean effort. We also provide examples of bias measures that match estimates of the mean and the median effort, and argue that there are, in general, no practical bias measures for estimates of the most likely effort. The paper concludes with implications for the evaluation of bias of software development effort estimates.

Authors: U. Sikder Iftikhar , J. Ribero James
Published: March 2022

The paper examines the bivariate relationship between COVID-19 and temperature time series using Singular Value Decomposition (SVD) and continuous cross-wavelet analysis. The COVID-19 incidence data and the temperature data of the corresponding period were transformed using SVD into significant eigen-state vectors for each spatial unit. Wavelet transformation was performed to analyze and compare the frequency structure of the single and the bivariate time series. The result provides coherency measures in the ranges of time period for the corresponding spatial units. Additionally, wavelet power spectrum and paired wavelet coherence statistics and phase difference were estimated. The result suggests statistically significant coherency at various frequencies. It also indicates complex conjugate dynamic relationships in terms phases and phase differences.
Deep Learning Framework Mindspore and Pytorch Comparison
Authors: XIA Xiangyu , ZHOU Shaoxiang
Published: March 2022

Deep learning has been well used in many fields. However, there is a large amount of data when training neural networks, which makes many deep learning frameworks appear to serve deep learning practitioners, providing services that are more convenient to use and perform better. MindSpore and PyTorch are both deep learning frameworks. MindSpore is owned by HUAWEI, while PyTorch is owned by Facebook. Some people think that HUAWEI's MindSpore has better performance than FaceBook's PyTorch, which makes deep learning practitioners confused about the choice between the two. In this paper, we perform analytical and experimental analysis to reveal the comparison of training speed of MIndSpore and PyTorch on a single GPU. To ensure that our survey is as comprehensive as possible, we carefully selected neural networks in 2 main domains, which cover computer vision and natural language processing (NLP). The contribution of this work is twofold. First, we conduct detailed benchmarking experiments on MindSpore and PyTorch to analyze the reasons for their performance differences. This work provides guidance for end users to choose between these two frameworks.
South African comprehensive universities' community engagement : $b towards establishment of a best practice framework for community engagement
Authors:   , Mkuzo Luleka
Published: March 2022

In this study, the researcher interrogated the core fundamental purpose of community engagement (CE) in an attempt to understand the role of higher education institutions in communities. Community engagement as a phenomenon is viewed with much ambiguity, having a very broad and open interpretation and being seen as both positive and negative by others. There is no governing document that mandates how institutions should develop, implement and monitor community engagement. Consequently, each institution has developed their own guiding documents as per their purpose, mission and context. In South Africa, the Higher Education Quality Committee (HEQC) focused on community engagement in higher education because it recognized the need for academic reconstruction. Community engagement was seen as a potentially powerful instrument that could be used in the transformation agenda in higher education. To date, this view has not changed. The challenge is to shift the academic perspective from the traditional notion of viewing university community engagement as charity to begin to see it as that of pedagogy. In working with five comprehensive universities and a total of fifty participants ranging from Community Engagement Directors, Managers, Project Leaders, students and community members, the study’s aim was to understand how community engagement is defined with regard to restraints, exclusions and inclusions. The study explores the nature of its definition; its purpose and challenges; utilizing a transformative approach proposes a framework that can be used as a guide to community engagement. The study revealed the need for both universities and communities to break their tangible and intangible boundaries to allow community engagement to be conducted in an effective manner using ubuntu, deep democracy and a scholarship approach that can bring about change and add value for both universities and communities. The study also revealed that the ambiguous contextual nature of community engagement makes it difficult for academics and community members to understand what it is, hence making it open for various universities to develop and implement it according to their own mission and vision. The study therefore recommends that community engagement be approached with a framework of Ubuntu, deep democracy and scholarship. Furthermore, there should be a clear funding model for community engagement or engaged scholarship, along with a monitoring and evaluation framework that measures the community engagement impact.

Authors: Ahsan Nasim  , Shafaq Ibrahim  , Naila Jabbar
Published: March 2022

Background: Treatment possibilities vary according to patient’s presenting complaints and stage of disease and range from topical applications and dietary modifications to office procedures like rubber band ligation and sclerotherapy to surgical management like hemorrhoidectomy and stapled anopexy. Among these procedures, rubber band ligation (RBL) and hemorrhoidectomy are the most frequently performed.

Objectives: To compare the outcome (in terms of post-operative pain and bleeding)of rubber band ligation versus Milligan Morgan hemorrhoidectomy in 3rd degree hemorrhoids.

Materials & Methods: Total 86 patients with 3rd degree hemorrhoids, 25-60 years of age of both genders were selected. Group A included the cases in which rubber band ligation was done while group B included the cases where Milligan Morgan hemorrhoidectomy was done. All the patients were assessed up to 72 hours for outcome (bleeding and post -operative pain).

Results: The mean age in group A was 38.58 ± 7.57 years and in group B was 38.21 ± 7.33 years. Out of 86 patients, 59 (68.60%) were males and 27 (31.40%) were females with ratio of 2.2:1. Patients with post-operative pain in Group A were 04 (9.30%) and in group B were 32 (74.42%) after hemorrhoidectomy (p-value = 0.0001). Post-operative bleeding was seen in 02 (4.65%) after rubber band ligation and in 12 (27.91%) after hemorrhoidectomy (p-value = 0.003).

Conclusion: This study concluded that the post-operative pain and bleeding is less after rubber band ligation in 3rd degree hemorrhoids as compared to Milligan Morgan hemorrhoidectomy.
USING THE ONTOLOGICAL MODEL OF THE STEM–CENTER IN THE EDUCATIONAL PROCESS
Authors: Shapovalov V. B.
Published: March 2022

The article is devoted to the practical aspects of using the ontological model of the STEM Center, which is built on the basis of cognitive information technology “Polyhedron”, in educational and research processes. Tools created using Microsoft and Google Spreadsheets are described. The application of the system of virtual museum Laboratories, a database of microorganisms, an ontological STEM classifier, a virtual laboratory of scientific publica­tions, ontological virtual laboratories of expeditions, and a cognitive system for selecting research papers is analyzed. All tools of the CIT “Polyhedron” can be represented as a taxonomy, object-oriented, or prism. Approaches to data processing using ranking and auditing, which are elements of the CIT “Polyhedron”, have been developed. This ap­proach is used in the selection of data by teachers and students, as well as in the processing of ontological knowledge bases, which is shown on the example of the microbial selection system. The database of a centralized information web-oriented educational environment consists of various types of educational programs. The ontologized program differs from the classical approaches to the interpretation of educational programs by a higher level of structured material and interactivity. Students and teachers can interact with structured curricula. Internal and external search tools are used to search for contexts based on the program’s terminology field. The ontological system of virtu­al museum laboratories provides a high level of structuring of information about objects and their virtualization. This allows you to use Museum ontologies during sightseeing classes. The database of microorganisms in the CIT “Polyhedron” system provided systematization of research knowledge in the educational process. CIT “Polyhedron” made it possible to identify the characteristics of research papers and systematize their processing in accordance with the user’s request.

Published: March 2022

Abstract. This paper concerns an in-depth analysis of an
exceptional incursion of mineral dust over southern Europe in late March
2020 (27–30 March 2020). This event was associated with an anomalous
circulation pattern leading to several days of PM10 (particulate matter with an aerodynamic diameter less than 10 µm) exceedances in
connection with a dust source located in central Asia; this is a rare source of dust for Europe, which is more frequently affected by dust outbreaks from the Sahara
Desert. The synoptic meteorological configuration was analyzed in detail,
and the aerosol evolution during the transit of the dust plume over northern
Italy was assessed at high time resolution by means of optical particle
counting at three stations, namely Bologna, Trieste, and Mt. Cimone,
allowing for the revelation of the transport timing among the three locations.
Back-trajectory analyses supported by Copernicus Atmosphere Monitoring Service (CAMS) maps allowed for the location of the mineral dust source area in the Aralkum region. Therefore, the event was analyzed by observing the particle number size distribution with the support of chemical composition analysis. It is shown that the PM10 exceedance recorded is associated with a large fraction of coarse particles, which is in agreement with mineral dust properties. Both the in situ number size distribution and the vertical distribution of the dust plume were cross-checked using lidar ceilometer and aerosol optical depth (AOD) data from two nearby stations and showed that the dust plume (in contrast to those originating from the Sahara Desert) traveled close to the ground (up to a height of about 2 km). The limited mixing layer height caused by high concentrations of absorbing and scattering aerosols caused the mixing of mineral dust with other locally produced ambient aerosols, thereby potentially increasing its
morbidity effects.
Fill dynamics and sample mixing in the AirCore
Authors: Tans Pieter
Published: March 2022

Abstract. The AirCore is a long coiled tube that acts as a “tape recorder” of the
composition of air as it is slowly filled or flushed. When launched by
balloon with one end of the tube open and the other closed, the initial fill air flows out during ascent as the outside air pressure drops. During
descent atmospheric air flows back in. I describe how we can associate the
position of an air parcel in the tube with the altitude it came from by
modeling the dynamics of the fill process. The conditions that need to be
satisfied for the model to be accurate are derived. The extent of the mixing of
air parcels that enter at different times is calculated so that we know how many independent samples are in the tube upon landing and later when the AirCore is analyzed.
The volcanic 'triple event' of the 160s BCE and the causes of famine in Judaea during the Maccabaean Revolt
Authors: Medenieks Selga
Published: March 2022

Ongoing research shows an association between volcanic eruptions, the resulting disruption of climatic and hydrological patterns, and socio-economic disturbance in ancient Egypt during the final three centuries BCE (Manning, Ludlow et al. 2017). The present paper explores how this paradigm can extend our understanding of Judaea in the 160s BCE, a decade marked by consecutive famines amid intense political and social upheaval, particularly the so-called Maccabaean Revolt against Seleucid rule. Making use of state-of-the-art ice-core evidence that identifies three substantial volcanic eruptions within that timespan, as well as modelling that sheds light on the likely climatic impacts of the eruptions, this paper puts forward explanations to supplement those based upon the ancient (literary) sources alone, suggesting that volcanic forcing was a critical factor in these significant events in Judaean history. 

            The Maccabaean rebellion and its aftereffects on Jewish identity politics in posterity cannot be overstated, yet heretofore the contribution of famine conditions (now plausibly linked to external climatic forcing) to this watershed period have hardly been taken into account. Mindful that studies claiming climatic pressures as primary catalysts of important human historical events have often proved overly simplistic, the interaction of other contemporaneous stressors is also examined. Correspondences with the Egyptian and Chinese data are observed here too, especially in relation to conditions surrounding the onset and cessation of military action, and interference in religious matters in order to control a predominantly Temple-managed resource management and taxation system.
Persistent ISOW formation during MIS 11
Authors: Link Jasmin M. , Frank Norbert
Published: March 2022

The deep water formation in the Labrador and Nordic Seas is crucial for the global thermohaline circulation nowadays and it remains debated whether changing boundary conditions in terms of global warming may influence the deep convecting activity. Deep convection leads to the formation of Iceland Scotland Overflow Water (ISOW), which is an essential part of the lower limb of the Atlantic Meridional Overturning Circulation (AMOC). However, surface conditions in the Nordic Seas were unlikely always favorable for the formation of deep water in the past.

During Marine Isotope Stage (MIS) 11, a strong and active AMOC [e.g. 1] was reconstructed, which also contributed to the mass loss of the Greenland Ice Sheet [2]. However, cold and fresh surface conditions prevailed in the central Nordic Seas [3], which have been ascribed to freshwater input from the higher latitudes [4]. Thus, the question arises, whether and where deep water formation took place in the Nordic Seas.

Here, we reconstruct authigenic neodymium isotopes extracted from deep sea sediment from the Gardar Drift from 470 to 374 ka. IODP Site U1304 is located directly in the modern flow path of ISOW and should therefore sensitively track changes of this water mass in the past. Today, it is characterized by a strongly radiogenic neodymium isotopic composition, which markedly differs from other North Atlantic water masses.

Starting right at the onset and for the full length of the interglacial MIS 11c, a radiogenic Nd isotopic composition is switched on and prevailed indicating the presence of ISOW at the core site. More unradiogenic conditions indicate the return to glacial like conditions during a short event in MIS 11b. However, during MIS 11a the radiogenic values point again to a persistent presence of ISOW.

Thus, although the boundary conditions in terms of freshwater fluxes and sea level were significantly differing in the central Nordic Seas, the deep water formation presumably happened in the southern part of the Nordic Seas. This led to the active formation of ISOW, which in turn helped drive the active and strong AMOC during MIS 11.

Extreme meteorological droughts from paleo-climatic reconstructions analyzed through non-asymptotic extreme-value distributions
Authors: Caruso Maria Francesca , Peres David Johnny , Cancelliere Antonino , Marani Marco
Published: March 2022

Drought is a complex and multifaceted natural phenomenon whose effects may have serious environmental and socio-economic impacts on communities. Drought is a multi-year phenomenon and thus its probabilistic characterisation needs long instrumental records. As a possible way to overcome the limitation posed by the paucity of long-term historical records of hydro-meteorological variables, in this work we aim at using paleo-climate reconstructions from tree-ring records, which are becoming increasingly available (International Tree-Ring Data Bank, ITRDB, accessible from the repositories of the NOAA's National Centers for Environmental Information). On the other side, we attempt to find the statistical link of paleo-climate data with drought characteristics identified on indices largely used in the literature, such as the Standardised Precipitation-Evapotranspiration Index (SPEI). In particular, we determine drought events and their properties (severity, duration, and intensity) using threshold methods based on the statistical “theory of runs”. We then explore the potentialities of using the recently-proposed Metastatistical Extreme Value Distribution (MEVD) to estimate the probability of occurrence of extreme drought events of different severity, duration, or intensity at several European sites. Unlike the statistical approaches based on the traditional Extreme Value Theory, the MEVD framework minimizes estimation uncertainty by leveraging the information content of all the ordinary values (i.e. those in the main body of the probability distribution).
More in detail, in this work we focus on: (1) tests of the reliability of these paleo-climatic reconstructions in reproducing meteorological droughts in long observational records (> 100 years), (2) comparisons of SPEI-based drought analyses at different timescales (3, 6, 12, 24 months), (3) the statistical analysis approach affording minimal uncertainty in the estimation of extreme drought events with assigned probability of exceedance, and (4) how the severity and timing of impacts vary across and within drought-affected areas.
