Authors: Saad Bassem B. , Tharwat Ayman I. , Ghobrial Haidi N. , Elfawal Sanaa M.
Published: September 2020

Background

The pre-operative period is a very stressful event for most of the individuals undergoing surgery especially the pediatric patients. So, relieving their pre-operative anxiety becomes an important concern for an anesthesiologist. Many anesthetic pre-medications are used to relieve this stress response. Of these pre-medications, midazolam and dexmedetomidine are effectively used as sedatives. The present study was planned to compare intranasal dexmedetomidine with intranasal midazolam as a pre-anesthetic medication in children. Forty-eight children aged 3–7 years, of either sex, weighing 13–22 kg, with American Society of Anesthesiologists (ASA) physical status 1 and undergoing elective adenotonsillectomy surgery were enrolled in this comparative prospective, double blinded, randomized clinical study. The children were divided into 2 groups: group D and group M, of 24 each. Forty-five minutes before induction of anesthesia, group D (n= 24) received intranasal dexmedetomidine at a dose of 1 μg/kg and group M (n= 24) received intranasal midazolam of 0.2 mg/kg.

Results

Children who were pre-medicated with dexmedetomidine had lower sedation scores, lower anxiety levels, easier child-parent separation, better mask acceptance, and lower pain scores than those who received midazolam. The incidence of emergence agitation was decreased in both groups with no significant difference.

Conclusion

Intranasal dexmedetomidine seems to offer some advantages compared with midazolam. Thus, it can be used effectively and safely as a pre-anesthetic medication in children undergoing any surgical procedures under general anesthesia.

Published: September 2020

Genetically engineered mouse models through gene deletion are useful tools for analyzing gene function. To delete a gene in a certain tissue temporally, tissue-specific and tamoxifen-inducible Cre transgenic mice are generally used. Here, we generated transgenic mouse with cardiac-specific expression of Cre recombinase fused to a mutant estrogen ligand-binding domain (ERT2) on both N-terminal and C-terminal under the regulatory region of human vasoactive intestinal peptide receptor 2 (VIPR2) intron and Hsp68 promoter (VIPR2-ERT2CreERT2). In VIPR2-ERT2CreERT2 transgenic mice, mRNA for Cre gene was highly expressed in the heart. To further reveal heart-specific Cre expression, VIPR2-ERT2CreERT2 mice mated with ROSA26-lacZ reporter mice were examined by X-gal staining. Results of X-gal staining revealed that Cre-dependent recombination occurred only in the heart after treatment with tamoxifen. Taken together, these results demonstrate that VIPR2-ERT2CreERT2 transgenic mouse is a useful model to unveil a specific gene function in the heart.

Published: September 2020

Background

Diabetes mellitus is clinically underlined by hyperglycemia and dyslipidemia. In view of this, the current study assessed the glycemic and lipidemic control potentials of methanol extract of Sruchium sparganophora leaves (SPA) in the alloxan-induced diabetic model using male Wistar rats. Experimental diabetes was induced through a single intraperitoneal injection of 120 mg/kg freshly prepared alloxan. Thirty-six rats were randomly assigned into six groups of normoglycemic control, untreated diabetic group, and diabetic treated with (i) metformin (12 mg), (ii) metformin 12 mg + SPA 300 mg/kg, (iii) SPA 300 mg/kg, and (iv) SPA 600 mg/kg per os twice at 9.00 and 18.00 h daily for 10 days. Fasting blood glucose (FBG) level and markers of dyslipidemia, and oxidative stress markers were determined.

Results

SPA at selected doses decreased fasting blood glucose which was significantly (p < 0.05) raised by alloxan. Increase in plasma total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and triglyceride (TG) concentrations and decrease in HDL-cholesterol (HDL-C) concentration (p < 0.05) caused by alloxan were significantly moderated by SPA at selected doses. Glutathione-s-transferase (GST), superoxide dismutase (SOD), and catalase (CAT) activities reduced by alloxan (p < 0.05) in both the liver and pancreas were reversed by SPA 300 and 600, and its combination with metformin. Decreased reduced glutathione (GSH) concentration in alloxan diabetic rats was also reversed by the extract, while the level of malondialdehyde (MDA) exacerbated by alloxan (p < 0.05) in the tissues was decreased by the extracts.

Conclusion

Struchium sparganophora possesses considerable antihyperglycemic, antidyslipidemic, and antioxidant potentials without compromising organ functionality.

Published: September 2020

Objective

To summarize our experience in the treatment of pituitary somatotroph adenomas by fractionated intensity-modulated radiotherapy (IMRT), describe the treatment outcomes, and determine predictors.

Methods and Materials

Patients with pituitary somatotroph adenoma treated by IMRT in our institution from August 2009 to January 2019 were reviewed. A total of 113 patients (37 male) were included in this study. The median age was 33 years (range 12-67 years). A total of 112 patients had not achieved complete remission after surgery, and 1 patient was treated by radiotherapy (RT) alone because she refused to surgery. The median growth hormone level was 8.6 ng/mL (range 2-186 ng/mL) and the median insulin-like growth factor (IGF)-1 level was 732 ng/mL (range 314-1485 ng/mL) pre-RT. The radiation doses to clinical target volume were usually 50-56 Gy in 25 to 30 fractions and to gross tumor volume were 60.2 Gy in 28 fractions while simultaneous integrated boost-IMRT used. After RT, the patients were followed up with endocrine testing every 6 to 12 months and magnetic resonance imaging annually. Endocrine complete remission was deﬁned as a normal sex- and age-adjusted IGF-1 level without any pituitary suppressive medications. The outcomes including endocrine remission and new hypopituitarism after RT were recorded. The median follow-up time was 36 months (range 6-105.5 months).

Results

The endocrine complete remission rates of IGF-1 at 1, 2, 3, and 5 years were 6%, 22.8%, 48.6%, and 74.3%, respectively. The median time to complete remission was 36.2 ± 3.8 months. The tumor control rate was 99% during the follow-up. The overall incidence of RT-induced hypopituitarism was 28.3% at the last follow-up. Univariate and multivariate analysis demonstrated that tumor sizes before RT, pre-RT IGF-1 level, and age significant predicted the endocrine remission.

Conclusions

IMRT is a highly effective treatment for pituitary somatotroph adenoma. Endocrine remission rate, tumor control rate, the median time to remission and hypopituitarism incidence are similar to stereotactic radiosurgery. Age and IGF-1 level before RT were significant predictive factors in endocrine remission.

Published: September 2020

Background

Currently acceptable management options for patients with adult papillary thyroid microcarcinoma (APTM) range from immediate surgery, either unilateral lobectomy or bilateral lobar resection, to active surveillance (AS). An alternative minimally invasive approach, originally employed for eliminating neck nodal metastases, may be ultrasound-guided percutaneous ethanol ablation (EA). Here we present our experience of definitively treating with EA 15 patients with APTM.

Patients and Methods

During 2010 through 2017, the 15 cT1aN0M0 patients selected for EA were aged 36 to 86 years (median, 45 years). Tumor volumes (n = 17), assessed by sonography, ranged from 25 to 375 mm3 (median, 109 mm3). Fourteen of 15 patients had 2 ethanol injections on successive days; total volume injected ranged from 0.45 to 1.80 cc (median, 1.1 cc). All ablated patients were followed with sonography and underwent recalculation of tumor volume and reassessment of tumor perfusion at each follow-up visit.

Results

The ablated patients have now been followed for 10 to 100 months (median, 64 months). There were no complications and no ablated patient developed postprocedure recurrent laryngeal nerve dysfunction. All 17 ablated tumors shrank (median 93%) and Doppler flow eliminated. Median tumor volume reduction in 9 identifiable avascular foci was 82% (range, 26%-93%). After EA, 8 tumors (47%) disappeared on sonography after a median of 10 months. During follow-up no new PTM foci and no nodal metastases have been identified.

Conclusions

Definitive treatment of APTM by EA is effective, safe, and inexpensive. Our results suggest that, for APTM patients who do not wish neck surgery and are uncomfortable with AS, EA represents a well-tolerated and minimally invasive outpatient management option.

The main texts under consideration in this article are two French-language Alexander romances written in the second half of the twelfth century, discussed in relation to the Latin historical, romance, and naturalist traditions that form the backbone of the medieval tradition of Alexander the Great in medieval Europe, and in particular in relation to the literary tradition that starts with Pseudo-Callisthenes’s Greek Romance of Alexander. The aim is to show how Alexander was used not simply as an icon of secular or military power but also as an important figure for understanding the relationship between the imagination, technological invention, and discovery of new knowledge, which necessarily entails questions of prestige and power. Alexander’s ingenuity, which manifests both as verbal trickery and in the invention of new machines, is shown to be fundamental for a certain model of knowledge-acquisition that sees natural truths as hidden and in need of tools to be extracted. This ingenuity is shown, also, to be closely connected to the inventions of writers of romance, and the article suggests the specific importance of the Alexander material in the history of medieval romance literature.
Analysis of Options Pricing Methods: the Black-Scholes Model and the Monte-Carlo Method
Authors: Yunusova Leysen
Published: September 2020

Currently, the market of financial instruments is quite developed. Traditional financial instruments prevail on the Russian market, while derivatives of these financial instruments (options, futures, forwards, bills, etc.) are faintly developed. The reason for this situation is that few participants in the financial market can correctly evaluate financial products. Scientific researchers and large companies use different methods of estimating the value of financial instruments in making strategic investment decisions, since incorrect calculations can be irreparable. Therefore, it is important to apply the appropriate pricing methodology to various derivative financial instruments. The topic of derivative financial instruments in terms of scientific and theoretical aspects has been worked out in sufficient volume, but as for the pricing of these instruments, there are some gaps. There is still no method for pricing derivatives that would allow you to accurately assess the value of financial instruments for subsequent effective investment decisions. In this article considers the methodology of pricing of derivative financial instruments using the Black-Scholes model and the Monte Carlo method. The presented estimation methods allow us to calculate the range of price values that allows us to provide the most accurate expected results.
Trust Your Data or Not—StQP Remains StQP: Community Detection via Robust Standard Quadratic Optimization
Authors: Bomze Immanuel M. , Kahr Michael , Leitner Markus
Published: September 2020

We consider the robust standard quadratic optimization problem (RStQP), in which an uncertain (possibly indefinite) quadratic form is optimized over the standard simplex. Following most approaches, we model the uncertainty sets by balls, polyhedra, or spectrahedra, more generally, by ellipsoids or order intervals intersected with subcones of the copositive matrix cone. We show that the copositive relaxation gap of the RStQP equals the minimax gap under some mild assumptions on the curvature of the aforementioned uncertainty sets and present conditions under which the RStQP reduces to the standard quadratic optimization problem. These conditions also ensure that the copositive relaxation of an RStQP is exact. The theoretical findings are accompanied by the results of computational experiments for a specific application from the domain of graph clustering, more precisely, community detection in (social) networks. The results indicate that the cardinality of communities tend to increase for ellipsoidal uncertainty sets and to decrease for spectrahedral uncertainty sets.
COVID-19 consent and return to elective orthopaedic surgery
Authors: Clough Timothy M. , Shah Nikhil , Divecha Hiren , Talwalkar Sumedh
Published: September 2020

Aims

The exact risk to patients undergoing surgery who develop COVID-19 is not yet fully known. This study aims to provide the current data to allow adequate consent regarding the risks of post-surgery COVID-19 infection and subsequent COVID-19-related mortality.

Methods

All orthopaedic trauma cases at the Wrightington Wigan and Leigh NHS Foundation Trust from ‘lockdown’ (23 March 2020) to date (15 June 2020) were collated and split into three groups. Adult ambulatory trauma surgeries (upper limb trauma, ankle fracture, tibial plateau fracture) and regional-specific referrals (periprosthetic hip fracture) were performed at a stand-alone elective site that accepted COVID-19-negative patients. Neck of femur fractures (NOFF) and all remaining non-NOFF (paediatric trauma, long bone injury) surgeries were performed at an acute site hospital (mixed green/blue site). Patients were swabbed for COVID-19 before surgery on both sites. Age, sex, nature of surgery, American Society of Anaesthesiologists (ASA) grade, associated comorbidity, length of stay, development of post-surgical COVID-19 infection, and post-surgical COVID-19-related deaths were collected.

Results

At the elective site, 225 patients underwent orthopaedic trauma surgery; two became COVID-19-positive (0.9%) in the immediate perioperative period, neither of which was fatal. At the acute site, 93 patients underwent non-NOFF trauma surgery, of whom six became COVID-19-positive (6.5%) and three died. A further 84 patients underwent NOFF surgery, seven becoming COVID-19 positive (8.3%) and five died.

Conclusion

At the elective site, the rate of COVID-19 infection following orthopaedic trauma surgery was low, at 0.9%. At the acute mixed site (typical district general hospital), for non-NOFF surgery there was a 6.5% incidence of post-surgical COVID-19 infection (seven-fold higher risk) with 50% COVID-19 mortality; for NOFF surgery, there was an 8.3% incidence of post-surgical COVID-19 infection, with 71% COVID-19 mortality. This is likely to have significance when planning a resumption of elective orthopaedic surgery and for consent to the patient. Cite this article: Bone Joint Open 2020;1-9:556–561.
Observation of vertical wind profiling with lidar based on correction of sensitivity
Authors: Shao Jiangfeng , Hua Dengxin , Wang Li
Published: September 2020

A high spectral resolution lidar (HSRL) for simultaneously detecting vertical wind, temperature, and the backscattering ratio in the troposphere is developed. The atmospheric temperature and vertical wind are determined by the Rayleigh scattering spectrum width and Mie scattering spectrum Doppler shift, respectively. The influence of temperature and the backscattering ratio on vertical wind measurement accuracy is also analyzed. The temperature and backscattering ratio affect the wind measurement, which produces the vertical wind offset. A correction considering the effects of the method is conducted considering real-time and on-site temperature profiles and the backscattering ratio to correct wind measurement sensitivity. Measurements of HSRL taken under different weather conditions (fine and hazy days) are demonstrated. Good agreement between the HSRL and the radiosonde measurements was obtained considering lapse rates and temperature inversions. The maximum temperature offsets were 1.3 and 4 K at a height of 1.5 km on fine and hazy days, respectively. Then, real-time and on-site temperature profiles and backscattering ratios were applied to correct the real-time and on-site wind. The corrected wind profiles showed satisfactory agreement with the wind profiles acquired from the calibrated wind lidar. The maximum detection offsets of the retrieved wind speed were reduced from 1 m/s to 0.55 m/s and from 1 m/s to 0.21 m/s, respectively, which were decreases of 0.45 and 0.79 m/s in fine and hazy days after correction of sensitivity. It is evident that the corrected wind method can reduce the influence of temperature and the backscattering ratio on the wind measurement and the offset of vertical wind. The reliability of the method is also proven.

Published: September 2020

Reliable operation of photonic integrated circuits at cryogenic temperatures would enable new capabilities for emerging computing platforms, such as quantum technologies and low-power cryogenic computing. The silicon-on-insulator platform is a highly promising approach to developing large-scale photonic integrated circuits due to its exceptional manufacturability, CMOS compatibility, and high component density. Fast, efficient, and low-loss modulation at cryogenic temperatures in silicon, however, remains an outstanding challenge, particularly without the addition of exotic nonlinear optical materials. In this paper, we demonstrate DC-Kerr-effect-based modulation at a temperature of 5 K at GHz speeds, in a silicon photonic device fabricated exclusively within a CMOS-compatible process. This work opens up a path for the integration of DC Kerr modulators in large-scale photonic integrated circuits for emerging cryogenic classical and quantum computing applications.

Tarteso y lo orientalizante. Una revisión historiográfica de una confusión terminológica y su aplicación a la cuenca media del Guadiana
Authors: Rodríguez González Esther
Published: September 2020

Este trabajo recoge una revisión del uso de términos como Tarteso y Orientalizante dentro de un mismo contexto cronológico y cultural, como es la arqueología del suroeste peninsular durante la I Edad del Hierro. Ambos conceptos son sometidos a un análisis terminológico e historiográfico con el objetivo de mostrar que no deberían ser empleados como sinónimos dentro de la literatura arqueológica. Como área de análisis se ha seleccionado el valle medio del Guadiana al tratarse de una de las regiones donde ambos conceptos son intercambiados con asiduidad ante el recelo de emplear el término Tarteso para definir la adscripción cultural de los yacimientos que jalonan la cuenca de este río entre los siglos VI-IV a.C.

With the increasing advancement of the Internet and Computing, digital information and communication technologies (DICTs) are increasingly present in everyone's life, whether at work, at home, in cars, or even in clothing, using wearable devices. Then comes the concept Internet of Things (IoT) which aims to interconnect objects with each other and with people through data transmission technologies and various sensors and actuators. With an infrastructure capable of managing them, these objects become "smart". In recent years, there have been increasing efforts to introduce IoT in schools, modifying not only its physical structure but also inserting it as a tool that can enhance interdisciplinary teaching in various activities. Thus, this paper aims to present basic IoT concepts for high school students from a public school in the city of Jandaia do Sul. For this, a didactic sequence was developed, using a smart home model, to demonstrate such concepts. With the sensors of the house, it is possible to demonstrate physics concepts, related to the students' daily life. At the end of the didactic sequence, a questionnaire will be applied to verify the learning process of the students.

Selective collection is an alternative way to minimize theenvironmental impact of waste that is disposed of and to reduce theproduction of misused waste. This work aims to raise awarenessamong children outside the literacy range, interactively teachingthe importance of selective collection. The proposal includes theconstruction of a prototype automated trash bin, made up ofelectronic components and controlled through the Arduinoplatform and the help of sensors and actuators. Thus, when the childapproaches the dumpster, a sound is emitted according to thematerial the dumpster receives, so the child deposits the wastecorrectly and consciously, without the need to be literate,interactively and associating that waste should be sorted anddisposed of properly. After prototyping, the assessment of learningwill be qualitative, through observation of the interaction of thechild with the trash, where the "hits" (correct disposal) can bequantified, as well as their reactions and perceptions.
Can Giraffes Become Birds? An Evaluation of Image-to-image Translation for Data Generation
Authors: Ruiz Daniel , Salomon Gabriel , Todt Eduardo
Published: September 2020

There is an increasing interest in image-to-image translation withapplications ranging from generating maps from satellite images tocreating entire clothes’ images from only contours. In the presentwork, we investigate image-to-image translation using GenerativeAdversarial Networks (GANs) for generating new data, taking as acase study the morphing of giraffes images into bird images. Morphinga giraffe into a bird is a challenging task, as they have differentscales, textures, and morphology. An unsupervised cross-domaintranslator entitled InstaGAN was trained on giraffes and birds,along with their respective masks, to learn translation betweenboth domains. A dataset of synthetic bird images was generatedusing translation from originally giraffe images while preservingthe original spatial arrangement and background. It is important tostress that the generated birds do not exist, being only the result of alatent representation learned by InstaGAN. Two subsets of commonliterature datasets were used for training the GAN and generatingthe translated images: COCO and Caltech-UCSD Birds 200-2011.To evaluate the realness and quality of the generated images andmasks, qualitative and quantitative analyses were made. For thequantitative analysis, a pre-trained Mask R-CNN was used for thedetection and segmentation of birds on Pascal VOC, Caltech-UCSDBirds 200-2011, and our new dataset entitled FakeSet. The generateddataset achieved detection and segmentation results close tothe real datasets, suggesting that the generated images are realisticenough to be detected and segmented by a state-of-the-art deepneural network.

Companies have migrated data from relational databases to NoSQLdatabases to improve their business through more active services ata lower operating cost, especially by the adoption of cloud services.This process is called Data Migration and is considered by someauthors one of the biggest challenges in systems engineering today.Although it is advantageous, the process of migrating data fromthe relational model to NoSQL models is not trivial and has led tothe development of different methodologies for this purpose. Theobjective of this work was to analyze and compare three differentmigration methodologies between Relational and NoSQL DocumentOriented databases under the following aspects: algorithminput, method documentation, migration process and generateddocuments. For that, different relational models were empiricallymigrated using such methodologies, allowing the analysis of theevaluated aspects. The results show that there is no consolidatedway to perform the migration and that the method to be chosendepends on the context of the application. So, scenarios that showwhen to use each method are presented. Although not performingcomputational tests, this work provides suggestions and insightsthrough the evaluation of the migration processes under the theoreticalmodels. It expected that the results presented here will helpIT managers decide on the best data model migration methodologyto follow in their actual projects.

The present article refers to the construction of a web application named Doai, capable of managing and promoting donations for non-governmental organizations (NGOs) and charities in the Piemonte Norte do Itapicuru - Bahia. From interviews with institutions’ managers, it became evident the lack of basic resources to maintain the continuity of the performed activities, It was also found that in many cases donations do not reflect your real needs. This demonstrates the lack of information between donors and these institutions. The problems experienced in these organizations was motivate the development this proposal, which aims to promote existing institutions in the region, with the modernization of dissemination actions, with the simplification of the donation process and with the resources available to leverage the contributions. After construction, the tool was submitted to analysis, with the participation of 73 (seventy-three) people from the region. In this research it was possible to realize that few people are involved with philanthropic activities. On the other hand, a large part of the public are motivated to donate using the tool, showing out how it offers good usability. In addition, much of the public also shows interest in virtual payment methods. From a technical point of view, the tool has a good user acceptance and meets the proposed requirements.

Dinâmica territorial do setor sucroenergético em Santa Vitória, Minas Gerais
Authors: Matos Patrícia Francisca de , Marafon Glaúcio José
Published: September 2020

No início do século XXI, ocorreu uma expansão acelerada no território brasileiro de produção de cana-de-açúcar, devido o projeto dos biocombustíveis, que colocou essa cultura como a principal opção na produção de álcool, criando novas paisagens, novas formas de produção e modificando os usos do território, especialmente, o estado de Goiás e Minas Gerais. O estado de Minas Gerais consolidou-se como um dos maiores produtores de cana-de-açúcar do país, em virtude da implantação de diversas usinas no seu território, com destacada importância para o Triângulo Mineiro/Alto Paranaíba. Cerca de 9,5% das 746.828.157 toneladas no Brasil, em 2018, foi produzido em Minas Gerais, e destes, 6,93%, produzidas no Triângulo Mineiro/Alto Paranaíba. A territorialização do setor sucroenergético, num curto espaço de tempo, metamorfoseou a estrutura produtiva, de forma que a cultura da cana-de-açúcar ocupou e ocupa o espaço. Todos esses municípios seguiram a tendência de crescimento desta monocultura em detrimento da diminuição de outras lavouras, promovendo novas territorialidades e novas configurações na paisagem, mediadas por uma lógica de produção globalizada de açúcar, etanol e energia.
A agricultura urbana como forma de uso e ocupação no espaço urbano
Authors: Gomes Ana Carla Alves , Cruz Maria Lúcia Brito da
Published: September 2020

A prática da Agricultura Urbana (AU) perpassa os aspectos de reprodução de atividades específicas do campo dentro das cidades, embora também englobe tal premissa, a AU surge como prática reconhecida pelo cultivo de culturas diversas e a criação de animais em áreas urbanas. Na cidade de Fortaleza essa atividade encontra-se espacializada em alguns bairros, dentre os quais se destaca o bairro Lagoa Redonda, por concentrar uma quantidade significativa de hortas, o que norteia o debate acerca da permanência dessas hortas frente aos diferentes usos que o solo urbano adquire principalmente no contexto das disputas territoriais do espaço urbano. Logo, versa sobre os benefícios e provisões que tal atividade exerce, a qual encabeça a reflexão de como o uso e a ocupação estabelecidos podem ser passíveis e possíveis de reprodução. A pesquisa utilizou levantamento bibliográfico e de dados secundários, visita em lócus no bairro, em órgãos e laboratórios específicos, bem como o auxílio das técnicas de geoprocessamento para análise e elaboração de material cartográfico. Os resultados fomentam a análise e compreensão da viabilidade de um uso e ocupação que aproveita os espaços para a reprodução da AU.
Editorial: God's Nature and Attributes
Authors: Lévi Ide , Pérez Alejandro
Published: September 2020

In Western theism, different attributes have classically been ascribed to God, such as omnipotence, omniscience, wisdom, goodness, freedom and so on. But these ascriptions have also raised many conceptual difficulties: are these attributes internally coherent? Are they really compossible? Are they compatible with what we know about the world (e.g. the existence of evil, human freedom, the laws of nature etc.). These traditional questions are part of the inquiry on God’s nature as it is carried out in contemporary philosophy of religion. Another part of this inquiry is constituted by theological and philosophical questions raised by more precise or particular religious conceptions of God – e.g. the doctrine of Trinity in Christianity, or other specific credentials about the right way to understand God’s perfection and absolute transcendence in Judaism, Christianity or Islam.

In this issue, we propose to follow these two directions of the inquiry about God’s nature and attributes through historical and systematic studies, in the perspective of contemporary philosophy of religion and analytical theology. While the three papers specifically dedicated to the problem of the Trinity pertain mainly to the second part of the examination (the conceptual analysis of specific credentials and theological doctrines), the three others offer new perspectives and arguments on traditional questions about God, like the problem of evil, perfect goodness, or the problem of divine perfection and God’s freedom.
Rawls Goes to Church
Authors: Fischer Bob
Published: September 2020

Many mainline Protestant communities want to be welcoming while preserving their identities; they want to be shaped by the central claims of the faith while making room for those who doubt. And crucially, they want to do this in a way that leads to vibrant, growing communities, where more and more people gather to worship, encourage one another, and live out the Gospel. How should the Episcopal Church—and other mainline Protestant denominations, insofar as they’re similar—try to achieve these goals? I suggest that local churches borrow some resources from John Rawls’s Political Liberalism. On the view I outline, it’s valuable for local churches to see themselves as akin to political bodies composed of reasonable citizens. The idea, in essence, is that the relevant kind of reasonableness would make congregations more unified even while tolerating more diversity, and would accomplish all this without giving up their distinctly Christian identity.
Seeing the Face of Christ
Authors: King Derek S
Published: September 2020

The problem of the hiddenness of God has at least two kinds: an experiential and an intellectual problem. Despite differences, a solution to either would require some account of how God is personally known. Yet for the Christian tradition, God is known in the man Jesus Christ. I suggest, then, a Christological reformulation of the hiddenness argument, and proceed to offer an account of how Christ is known. With special attention to the ecclesiology of Gregory of Nyssa, I offer an account of knowing Christ in the church. I then explore this as a response to the problems of divine hiddenness, and anticipate a considerable objection to my response.
Credo in unam sanctam…
Authors: Zafeiropoulos Alejandro
Published: September 2020

Is the Church of Christ the Roman Catholic Church? Could it be argued in parallel that the Church of Christ is the Orthodox Church? And could one accept a positive answer to these first two questions and still affirm that the Roman Catholic Church is not the Orthodox Church, and all this avoiding both a logical and a metaphysical contradiction? In this article I shall respond positively to each of these questions, avoiding the possible contradiction that such responses might involve. Taking as a starting point the philosophical and theological discussion of the Trinity within the analytical mainstream, I shall present the outline of an ecumenical ecclesiology based on the metaphysical relation of constitution. Thanks to this strategy, it is possible to think of a universal ecclesiology capable of explaining better not the diversity but the unity of the Church of Christ.

Resumen: ¿La Iglesia de Cristo es la Iglesia católica romana? ¿Podría defenderse paralelamente que la Iglesia de Cristo es la Iglesia ortodoxa? Y, ¿se podría aceptar una respuesta positiva a estas dos primeras preguntas y afirmar que la Iglesia católica romana no es la Iglesia ortodoxa, y todo esto evitando tanto una contradicción lógica como metafísica? En el presente artículo se desea responder de manera positiva a cada una de estas preguntas, evitando la posible contradicción que dicha respuesta podría involucrar. Para esto y tomando como punto de partida las discusiones filosóficas y teológicas sobre la Trinidad dentro de la corriente analítica, presentaremos el bosquejo de una eclesiología ecuménica basada en la relación metafísica de constitución. Gracias a esta estrategia, se puede pensar una eclesiología universal capaz de explicar mejor, no la diversidad sino la unidad de la Iglesia de Cristo.

On the Economic Focus of Conciliar Trinitarianism
Authors: O'Byrne Declan
Published: September 2020

This article suggests that the shape of Conciliar Trinitarianism is rather different to what is often supposed in recent theological treatments of the Trinity. Conciliar Trinitarianism does support the claims of the consubstantiality of the Son and the full divinity of the Spirit, but is not directly concerned with a doctrine of One God in three persons in abstraction from the economy of salvation. The economy (οἰκονομία) is not taken as the starting point for knowledge of the “immanent Trinity”. Instead, claims about Trinity in itself ground claims about the economy of salvation.
Defining and Supplementing Conciliar Trinitarianism
Authors: Torrance Alexis
Published: September 2020

This article constitutes a brief reply to Timothy Pawl's clear and insightful article on Conciliar Trinitarianism (defined as the Trinitarian theology of the Ecumenical Councils from Nicaea I to Nicaea II). The two basic arguments of that article (regarding the relationship between divine persons and divine nature and the debate over possible subordinationism) are celebrated rather than challenged. I instead offer three short comments. The first concerns the limited nature of the conciliar texts for the articulation of highly developed Trinitarian theology, and thus the question of methodology as it applies to Conciliar Trinitarianism. The second comment argues that the question of strict identity in the Godhead can be extended beyond the relationship of divine person and divine nature to the question of divine nature and divine power, will, and energy. The third comment argues that Pawl gives undue weight to a line from Cyril of Alexandria for a discussion of the Holy Spirt's mode of origination, and not enough weight to the clause related to the Holy Spirit articulated at the First Council of Constantinople, which recurs in one way or another at each of the subsequent Ecumenical Councils, up to and including Nicaea II. These three comments serve more as a supplement than a challenge to Pawl's original article, providing three further avenues for scholarly deliberation on the matter of Conciliar Trinitarianism.

El Centro Forestal Tropical (CFT) Pedro Antonio Pineda (Buenaventura, Colombia) es el principal centro rural de formación académica de la Facultad de Ingeniería Forestal de la Universidad del Tolima, el cual se ubica en territorio del consejo comunitario de comunidades afrodescendientes. Entre 2013 y 2017 se realizaron observaciones en siete localidades asociadas a tres tipos de hábitat (áreas abiertas, borde de bosque e interior de bosque), principalmente en abril y septiembre para aportar al conocimiento de las aves del bosque húmedo tropical del CFT. Se registraron 166 especies (20 órdenes y 40 familias taxonómicas); el orden con mayor abundancia relativa fue Passeriformes (62.6 %) y las familias con mayor abundancia relativa fueron Thraupidae (17.3 %) y Tyrannidae (8.9 %). Se registraron 22 especies casi endémicas y 31 con estatus migratorio; desde un contexto regional la mayoría de las aves fueron registradas en áreas abiertas (44 especies) seguidas por especies de borde de bosque (42 especies).
