How to create an interactive dashboard using R: the example of the Queensland COVID-19 tracker
Authors: Loginova Julia , Wohland Pia
Published: December 2020

Background  Interactive tools like data dashboards enable users both to view and interact with data. In today’s data-driven environment it is a priority for researchers and practitioners alike to be able to develop interactive data visualisation tools easily and where possible at a low cost.

Aims  Here, we provide a guide on how to develop and create an interactive online data dashboard in R, using the COVID-19 tracker for Health and Hospital Regions in Queensland, Australia as an example. We detail a series of steps and explain choices made to design, develop, and easily maintain the dashboard and publish it online.

Data and methods  The dashboard visualises publicly available data from the Queensland Health web page. We used the programming language R and its free software environment. The dashboard webpage is hosted publicly on GitHub Pages updated via GitHub Desktop.

Results  Our interactive dashboard is available at https://qcpr.github.io/.

Conclusions  Interactive dashboards have many applications such as dissemination of research and other data. This guide and the supplementary material can be adjusted to develop a new dashboard for a different set of data and needs.
Exploring the Mass Segregation Effect of X-Ray Sources in Globular Clusters. IV. Evidence of Black Hole Burning in ω Centauri
Authors: Cheng Zhongqun , Li Zhiyuan , Wang Wei , Li Xiangdong , Xu Xiaojie
Published: December 2020

Using X-ray sources as sensitive probes of stellar dynamical interactions in globular clusters (GCs), we study the mass segregation and binary burning processes in ω Cen. We show that the mass segregation of X-ray sources is quenched in ω Cen, while the X-ray source abundance of ω Cen is much smaller than other GCs, and the binary hardness ratio (defined as

, with f

b
being the binary fraction,

and L

K
being the cumulative X-ray and K-band luminosity of GCs, respectively) of ω Cen is located far below the

correlation line of the dynamically normal GCs. This evidence suggests that the binary burning processes are highly suppressed in ω Cen, and other heating mechanisms, very likely a black hole subsystem (BHS), are essential in the dynamical evolution of ω Cen. Through the black hole burning processes (i.e., dynamical hardening of the BH binaries), the BHS is dominating the energy production of ω Cen, which also makes ω Cen a promising factory of gravitational-wave sources in the Galaxy.

Published: December 2020

In 2017, 2018, and 2019, comets 46P/Wirtanen, 45P/Honda–Mrkos–Pajdusakova, and 41P/Tuttle–Giacobini–Kresak all had perihelion passages. Their hydrogen comae were observed by the Solar Wind ANisotropies (SWAN) all-sky hydrogen Lyα camera on the SOlar and Heliospheric Observer (SOHO) satellite: comet 46P for the fourth time and comets 45P and 41P for the third time each since 1997. Comet 46P/Wirtanen is one of a small class of so-called hyperactive comets whose gas production rates belie their small size. This comet was the original target comet of the Rosetta mission. The SWAN all-sky hydrogen Lyα camera on the SOHO satellite observed the hydrogen coma of comet 46P/Wirtanen during the apparitions of 1997, 2002, 2008, and 2018. Over the 22 yr, the activity decreased and its variation with heliocentric distance has changed markedly in a way very similar to that of another hyperactive comet, 103P/Hartley 2. Comet 45P/Honda–Mrkos–Pajdusakova was observed by SWAN during its perihelion apparitions of 2001, 2011, and 2017. Over this time period, the activity level has remained remarkably similar, with no long-term fading or abrupt decreases. Comet 41P/Tuttle–Giacobini–Kresak was observed by SWAN in its perihelion apparitions of 2001, 2006, and 2017 and has decreased in activity markedly over the same time period. In 1973 it was known for large outbursts, which continued during the 2001 (two outbursts) and 2006 (one outburst) apparitions. However, over the 2001 to 2017 time period covered by the SOHO/SWAN observations the water production rates have greatly decreased by factors of 10–30 over corresponding times during its orbit.

Published: December 2020

Understanding the ecology and evolution of animal communication systems requires detailed data on signal structure and variation across species. Here, we describe the male acoustic signals of 50 species of Neotropical katydids (Orthoptera: Tettigoniidae) from Panama, with the goal of providing data and recordings for future research on katydid communication, evolution, ecology, and conservation. Male katydids were recorded individually using an ultrasound-sensitive microphone and high-sampling rate data acquisition board to capture both audible and ultrasonic components of calls. Calls varied enormously in duration, temporal patterning, peak frequency, and bandwidth both across and within subfamilies. We confirm previous studies showing that katydid species within the subfamily Pseudophyllinae produced short calls (<250 ms) at long intervals and we confirm that this is true for species in the subfamily Phaneropterinae as well. Species in the Conocephalinae, on the other hand, typically produced highly repetitive calls over longer periods of time. However, there were exceptions to this pattern, with a few species in the Conocephalinae producing very short calls at long intervals, and some species in the Phaneropterinae producing relatively long calls (1–6 s) or calling frequently. Our results also confirm previous studies showing a relationship between katydid size and the peak frequency of the call, with smaller katydids producing higher frequency calls, but the slope of this relationship differed with subfamily. We discuss the value of documenting the diversity in katydid calls for both basic studies on the ecology, evolution, and behavior of these species as well as the potential conservation benefits for bioacoustics monitoring programs.
Pogostemon guamensis Lorence & W.L.Wagner (Lamiaceae), a new species from Guam, Mariana Islands
Authors: Lorence David H. , Wagner Warren L. , Wood Kenneth R. , Johnson Gabriel
Published: December 2020

While undertaking a botanical survey of the Andersen Air Force Base on Guam (Mariana Islands) in 1994, botanists from the National Tropical Botanical Garden collected an unusual suffrutescent, non-aromatic member of the Lamiaceae family growing on limestone cliffs in the northeastern part of the island. Based on morphology and molecular data (trnLF, matK), it was determined to belong to the genus Pogostemon Desf., a genus previously unknown from the Micronesian, Melanesian, and Polynesian region. Moreover, the analysis also showed that it was not conspecific with P. cablin (patchouli), and of the species available to include in the phylogenetic analyses it is sister to P. hirsutus¸ a species from India and Sri Lanka. Differing from its congeners by its large, loose inflorescence 2.5–5 cm wide and up to 7 cm wide in fruit, it is here illustrated and described as a new species, Pogostemon guamensis Lorence & W.L. Wagner and its habitat and conservation status are discussed.

Histoire du/en FLE : une patrimonialisation au service de quels enjeux ?
Authors: Burrows Alice , Cros Isabelle
Published: December 2020

Cet article vise à interroger les enjeux liés à l’intégration de l’Histoire en formation FLE, afin d’évaluer dans quelle mesure cet enseignement a pu participer à la patrimonialisation de cette discipline et comment cet héritage commun est abordé. Le corpus, composé d’archives historiques de l’ancienne École de préparation des professeurs de français à l’étranger et des maquettes actuelles de Master FLE ainsi que d’entretiens réalisés auprès des enseignants et des étudiants, permet de mieux appréhender le positionnement des premiers et la réception des seconds. Au-delà de l’acquisition d’un savoir théorique ou de la transmission d’un héritage, enseigner l’histoire en/du FLE permet l’enrichissement d’un capital culturel professionnel en vue de la professionnalisation des enseignants, dans une approche historique appliquée à l’enseignement des langues.
Une archive pour l’histoire du français langue seconde : le Congrès pour l’extension et la culture de la langue française (1905-1913)
Authors: Savatovsky Dan , Jorge Muriel

On examine les caractéristiques matérielles et discursives des actes des trois sessions du Congrès international pour l’extension et la culture de la langue française (Belgique, 1905-1913). La fin du xix e -tout début du xx e  siècle, période particulière de la « guerre des langues », correspond à la prise de conscience d’une perte d’influence du français dans le monde et à des interrogations sur les moyens d'y faire face ainsi qu’à l’émergence de la francophonie comme notion pertinente d’une politique linguistique. La situation belge suscite des questions particulièrement vives quant au statut des dialectes et parlers régionaux dans l’enseignement du français.
Périodisation et bornes disciplinaires dans l’historiographie de l’enseignement du français en Angleterre
Authors: Coffey Simon
Published: December 2020

Cet article retrace, dans les grandes lignes, les éléments épistémologiques et méthodologiques qui ont façonné l’historiographie de l’enseignement du français en Angleterre. Ces éléments recouvrent la sélection de sources documentaires et de périodes traitées, deux facteurs qui sont inextricablement liés aux constructions disciplinaires du français. Dans un premier temps, sont présentées les périodes prédominantes dans l’historiographie de l’enseignement du français, périodes qui ne sont pas seulement chronologiques mais qui se distinguent également par différentes sortes de données et qui s’orientent même vers différentes constructions du savoir. Ensuite, sont explorés les mécanismes par lesquels ce savoir se construit et circule, notamment grâce à l’instauration des départements universitaires et à l’évolution des revues scientifiques.
The End of Lost: The Paradox of Serialized Television and the Experience of Loss
Authors: Clémot Hugo
Published: December 2020

That the viewers of the Lost TV series were so disappointed by its last episode has something to do with the philosophical problem of narrative closure. To resolve this conceptual difficulty, Noel Carroll has conceived an ‘erotetic’ model in which the impression of finality someone usually feels at the end of most films and TV episodes is due to the fact that the questions the viewers ask themselves in the course of following the plot finally get an answer. This theory thus seeks to explain not only the enthusiasm which the TV series succeeds in eliciting by intriguing viewers with accumulating mysteries, but also how the viewers feel let down in the end when they realize they have not been given all the keys to solve these mysteries. This erotetic model surely has at least a formal interest. One, however, has reasons to prefer, and reasons that can be found in Lost, a teleological model where the relations between questions and answers are better understood when we see them as a question of the relation between means and ends. Yet this teleological model presupposes that we can somehow know the goals of the characters and of the narrative. If that were not the case, nothing would make sense, indeed. Still we can only acknowledge our separateness from the characters and from the projected world and admit that we have no choice but to understand without being certain that we are not simply projecting goals that do not exist outside of our minds. TV series allow us to live a skeptical experience, which originates in what can be called the ‘series-following paradox’ which is that we could always choose to follow a numerical series or a TV series and to retrospectively modify the meaning of the numbers or past events which constitute it. This skeptical truth not only threatens the TV experience we undergo while watching our favorite shows, but it also affects our perception of the meaning of our own personal lives. It also gives us a chance to change and to reach a better self. In order to surmount this skeptical trial, the Lost TV series teaches us to contemplate the form of a finality which seems to design life, without being able to get a representation of its goal, a lesson which actually enables us to see the ending of Lost as a success.
Lost: a Shakespearean "Romance"?
Authors: Hatchuel Sarah , Laist Randy
Published: December 2020

Qu’est-ce qu’une romance shakespearienne ? Comment lire Lost à l’aune de Shakespeare ? Et comment, en retour, lire Shakespeare à l’aune de Lost ? Les quatre pièces dites « tardives » de Shakespeare, Pericles (1608), Cymbeline (1609), Le Conte d’hiver (1610) et La Tempête (1611), ont brouillé la frontière entre les genres en incorporant des épisodes tragiques tout en se terminant dans l’harmonie. Ces pièces ont mis au défi les catégories dramatiques et ont échappé aux définitions simples. Pérégrinations géographiques, jeu avec le temps, naufrages, morts qui n’en sont pas, conflits passés qui resurgissent dans le présent, enfants perdus, arnaques, déguisements, interventions magiques ou surnaturelles, rêves, coïncidences incroyables, retournements de situation, retrouvailles et rédemptions – les thèmes de la série Lost sont avant tout des éléments constitutifs des romances shakespeariennes et ont suscité les mêmes réactions de la part des spectateurs et des critiques. Lost, comme les romances de Shakespeare, ne nous donnerait-elle pas des clés pour appréhender les défis d’un siècle qui commence ?
Lost's Ending: the Junction of Time and Timeless Discourse
Authors: Lifschutz Vladimir
Published: December 2020

This text offers a questioning on the ending of Lost from a temporal and aesthetic angle. As it has been the source of many strong controversies, the conclusion of Lost gives us an opportunity to wonder about the way we watch the show. Through our deformulation theory, we shall analyze how fiction unravels before us while accomplishing the impossible junction of two antinomic temporal lines. The show sets up a strong connection with the TV viewer as it elaborates a final double-speech whose second listener is the TV viewer. Through a subtle and coherent final cut, the authors of Lost connect our experiences, the temporal lines, and the characters in a same goal: producing an emotional catharsis, whose scope tends to indefinitely engrave the fiction in the collective memory. Lost reminds us that the value of the ending also consists in having shared some affect with someone else, since Lost is a fiction about Lost characters who, during the last moments of the fiction, find themselves.

Published: December 2020

Clozapine is prescribed for resistant schizophrenia. It is usually associated with weight gain. There have been only a few reports of weight loss associated with clozapine treatment and we report two patients from Sri Lanka. The first patient lost 27% of bodyweight on clozapine while the second lost 17%. Both were clinically stable on clozapine, with marked reduction of psychotic symptoms. Adding risperidone helped to regain the lost weight in the described patients.

Rating scales are widely used in psychiatric practice to screen, diagnose, monitor symptoms, and for research purposes. Most scales utilized in psychiatry have been formulated in the West. Many rating scales are limited with regards to local use, as they have not been culturally adapted and validated to the Sri Lankan setting. We searched all relevant publications in journals indexed in PubMed, Scopus, and Google Scholar and dissertations in the Registry of Post Graduate Institute of Medicine, University of Colombo to identify relevant articles containing details on validation and adaption of rating scales for the Sri Lankan setting. We identified 31 scales validated for use in Sri Lanka.

Published: December 2020

Syrphids (Diptera: Syrphidae) are a diverse and widespread family of pollinating flies. Their diverse life history traits not only allow them to thrive in a wide range of habitats but also make them potential bioindicators of environmental change. Here, we report on their distributions from a previously understudied and undeveloped part of northern Ontario that is a large part of the third-largest wetland in the world. Samples were collected from across the region between 2009 and 2016, using numerous sampling methods. Of the 122 species identified from 1514 specimens, six are new provincial records to Ontario. Five species were collected over 800 km from their previously known ranges, some of which were west of the Rocky Mountains. Of all the trapping methods employed in the study, Malaise traps were found to be the most effective at catching syrphid species. This work updates known range and provincial records for more than 100 species of syrphids, bringing into clearer focus their distribution throughout this region.
The Window Fill Rate in a Multiple Location Inventory System with Periodic Review and Order Crossover
Authors: Giat Yahel
Published: December 2020

Deliveries in global supply chains are often made through lengthy shipping routes that are subject to many delays such as border crossings, inspections and so forth. Consequently, orders frequently crossover, that is, their order of arrival is not the same as the order that they were issued. In this paper we model a multiple location inventory system with Poisson demand and periodic review in which orders may crossover. The system’s performance measure is the window fill rate, i.e., the probability that a customer arriving to the system is served within her tolerable wait. We show that when spares are scarce the system’s overall performance decreases if spares are allotted equitably. Additionally, we show that there is a linear tradeoff between the tolerable wait and the number of spares needed to maintain a given performance level. The observations have practical implications to inventory mangers. First, that when resources are scarce it is optimal to cluster spares to only few locations. In contrast, when resources are abundant, then a more equitable solution is optimal. Second, that it is possible to design simple contracts that reward customers for their patience, or alternatively, that charge customers a premium for expedited service.
A Weighted Additive Model for Comparative Analysis on Demand Factors among Multiple Seasonal Products: Nationwide Demand of Japanese Alcoholic Beverages
Authors: Kurihara Tsuyoshi , Kawanaka Takaaki , Yamashita Hiroshi
Published: December 2020

The climate has recently been fluctuating globally. Such climate, which affects the demand for seasonal products, varies depending on geographical conditions. However, analysis models of previous studies on nationwide demand for seasonal products have not considered differences in climate attributed to different regions in the country. Therefore, in this study, focusing on the relationship between climate and region, we extract common characteristics on the nationwide demand factors for a seasonal product group (Japanese alcoholic beverages). We propose a new demand analysis model that enables a comparative analysis among multiple items, more accurately, cross-sectionally, and concisely by using two independent factors: meteorological factors by item and regional weights (demand). We develop a new algorithm using alternating least squares for the estimation problem of inseparable parameters generated by expressing these two factors in the form of products. The validity and effectiveness of the proposed model and algorithm were confirmed by empirical analysis using public data. This makes it possible to theoretically consider regional differences (climate and demand) for nationwide demand of seasonal products. Consequently, the proposed model can be used to conduct multifaceted analysis to situation changes such as climate fluctuations to realize effective sales and operation planning of seasonal products.

The Role of Secondary Metabolites Obtained from Medicinal and Aromatic Plants in Our Lives
Authors: Coşge Şenkal Belgin
Published: December 2020

Medicinal plants, which are used as drugs to prevent diseases, maintain health or cure diseases, take place in areas such as nutrition, cosmetics, body care, incense or religious ceremonies, while aromatic plants are used in different industrial areas to give fragrance and taste are used. Flora of Turkey has a rich plant diversity. Secondary metabolites such as essential oils, alkaloids, glycosides, saponins etc. are the most basic products of the industry directly or indirectly. The vast majority of medicinal and aromatic plants rich in secondary metabolites exhibit strong biological activity (antioxidant, antibacterial, etc.). Therefore, these secondary metabolites are widely used in the pharmaceutical industry. The most common and practical use of secondary metabolites, which are also used as natural insecticides, is in the form of herbal tea. In recent years, the more side effects of synthetic origin substances, especially the resistance of organisms against synthetic drugs used as antimicrobials, have increased the importance of natural herbal resources and medicinal plants carrying these substances. Therefore, there is no doubt that the demand for secondary metabolites, which are natural products, will increase in the future. Flora of Turkey is an important source for natural products which will be developed newly.
Role of Follicle Size, IGF-I, Glucose and Hormones on Nuclear Maturation Events of Awassi Sheep Oocytes (Ovis aries)
Authors: Mardenli Omar
Published: December 2020

This experiment aimed to study the combined effect of each of the follicle size, insulin-like growth factor (IGF-I), glucose and hormones (growth hormone (GH) and luteinizing hormone (LH)) on different phases of in vitro nuclear maturation of Awassi sheep oocytes. Follicles diameters were divided into two main groups: small follicles (SF): 1-2 mm and large follicles (LF): >2 mm. The levels (μg/ml) of Insulin-Like Growth Factor (IGF-I), GH, LH and glucose (mM) were determined according to two increasing shared concentrations (A:5,5,1 and 50; B:10,5.5,5 and 100 respectively). The maturation events were monitored at 7-time intervals (0,3,6,9,12,21 and 27 hours). Before incubation (0 - hour time interval), the oocytes in SF group outperformed their counterparts of LF group in the germinal vesicle phase (92.45% Vs 74.46%; p=0.01). Down to the 6- hour time interval, the oocytes in B solution achieved the highest rates (24.52%; LF group),  After 9 hours of incubation, the differences appeared clearly in the prometaphase -1(p=0.05) as half of the number of oocytes in B solution reached the stage (53.84%; LF group), the rates did not exceed 31.37% (A solution; SF group). In the 12 - hour time interval, the pro -metaphase-1 rates across the four groups reached the values :34.00% (A solution; SF group), 40.00% (B solution; LF group), 53.84% (A solution; SF group) and 58.49% (B solution; LF group) respectively. Upon 21- hour time interval, oocytes across the different groups showed a significant difference in metaphase-I (p=0.01) with the superiority of oocytes of B solution (33.96%; LF group). At the 24- hour time interval, the rates of oocytes involved in the metaphase-II were sub-intermediate and ranged between 20.00% and 36.00% without statistical significance. The final time interval (27- hours of incubation) showed a significant difference in the rates of the metaphase-II (p=0.002), as the oocytes of B solution showed a great superiority (84.61%; LF group). It is concluded from this study that the maturation of oocytes derived from large follicles (>2 mm) in a mixture of IGF-I, GH, LH (μg/ml) and glucose (mM) with the levels 10,5.5,5 and 100 respectively led to a significant increase in the rates of metaphase-II.

Bitkisel üretimde ekonomik verim kaybına neden olan en önemli faktörlerden birisi de yabancı otlardır. Yabancı otlar kültür bitkileri ile rekabete girerek ve allelopatik etkileri ile kültür bitkilerini olumsuz etkilemeleri yanında kültür bitkileri üzerinde parazit olarak yaşamak suretiyle verim ve kalite kayıplarına neden olmaktadırlar. Çalışma ile Siirt ili genelinde görülen parazitik yabancı ot türlerinin ve rastlanma sıklıklarının belirlenmesi amaçlanmıştır. Sürvey çalışmaları 2018-2019 yıllarında ve ili temsil edecek şekilde toplam 105 noktada yürütülmüştür. Çalışmalar sonucunda tam parazitik karekter gösteren Orabanche cinsine ait 3 tür (Orobanchea egyptiaca Pers., Orobanche crenata Forssk. ve Orobanche ramosa L.), Cuscuta cinsine dahil 2 tür (Cuscuta approximata Bab., Cuscuta campestris Yunck.) saptanmıştır. Ayrıca bölgede ormanlık alanlarda meşe türlerinde sorun olan ve yarı parazitik nitelik gösteren Viscum album L. ve Loranthus europaeus Jacq. türlerine de rastlanmıştır. Bölgede belirlenen parazitik yabancı otlara konukçuluk yapan kültür bitkileri ile yabancı otlar da listelenmiştir. Tarımsal açıdan Orobanche türlerine özellikle mercimek ve domates tarlalarında sıklıkla rastlandığı ve önemli düzeyde ekonomik kayıplara neden oldukları saptanmıştır. Bölgede parazit yabancı otlardan kaynaklanan verim kayıplarının önlenmesi için entegre yabancı ot idare stratejilerine ihtiyaç duyulduğu görülmüştür. Ancak üreticilerin konuya ilişkin bilgi birikimlerindeki eksiklik dikkate alınarak öncelikle konuya ilişkin yayım çalışmalarının öncelikle yapılması gerektiği kanaatine varılmıştır.

Bedside Shift Report: A Way to Improve Patient and Family Satisfaction with Nursing Care
Authors:   , Pevec Audriana
Published: December 2020

Poor communication during the handoff process contributes to approximately 30% of malpractice claims costing up to $1.3 billion annually (Fenner, 2017), which demonstrates the importance of evaluating the quality of information exchange between nurses, patients, and families when associating quality of care to patient satisfaction (Kullberg et al.,2017). The following question guided this Evidence-Based Project (EBP) project. In adult, progressive care unit patients (P), does the implementation of a nursing bedside handoff (I) compared to current handoff practices (C) improve patient/family satisfaction with nursing care (O) over eight weeks (T)? The literature revealed evidence from 10 studies answering the practice problem and supported implementing a Bedside Handoff (BSH) bundle. Themes from the evidence included patient and family participation in care, bedside handoff and impact on patient and family satisfaction, nursing perceptions associated with bedside handoff process, and measuring patient and family satisfaction with nursing care. The BSH bundle included staff education, utilization of a standardized handoff communication tool, safety checks, and use of patient whiteboards. Direct observation occurred to understand staff compliance using the Handoff Observation Feedback Audit Tool. The project demonstrated that bundling evidence-based practices improved specific nursing care aspects that influence the patient and staff experiences and satisfaction survey results.
A Pain Control Optimization Pathway to Reduce Acute Postoperative Pain and Opioid Consumption Postoperatively: An Approach to Battling the Opioid Epidemic
Authors:   , Franson Holly
Published: December 2020

Practice Problem: Healthcare providers worldwide are working to battle the opioid epidemic and reduce opioid-related harm to patients. Utilizing evidence-based acute pain management methods to reduce opioid consumption is critical to combat the problem. PICOT: The PICOT question that guided this project was: In opioid-naïve adult patients undergoing general anesthesia for out-patient, minimally invasive abdominal wall hernia surgery, how does the implementation of an evidence-based, preventative Pain Control Optimization Pathway (POP) using a multimodal, opioid-sparing acute pain management technique and standardized procedure-specific opioid prescribing, compared to standard treatment, affect postoperative pain scores and opioid consumption, upon discharge from the recovery room and 72 hours postoperative? Evidence: Evidence supported utilizing a multimodal, opioid-sparing acute pain management technique, patient counseling, and opioid prescribing guidelines to improve outcomes among opioid-naïve patients undergoing abdominal surgeries. Intervention: In this pre- and post-intervention evaluation, N = 28 patients received the POP care process during the perioperative period. Outcome: Results showed the mean pain score at discharge from the recovery room decreased from 4.8 to 2.82 on the 10-point Numeric Rating Scale post-intervention (p< 0.001). Also, provider compliance with prescribing a procedure-specific opioid prescription increased from 73% to 100%, thus reducing opioid exposure and access. Conclusion: This project provided evidence that utilization of the innovative POP care process provided optimal pain control and decreased opioid consumption, consequently reducing the risk of new persistent opioid use.
Reducing Suicide by Providing Cognitive Behavioral Therapy for Suicide Prevention
Authors:   , Larkin Wendy
Published: December 2020

Veteran suicide is a serious and persistent national problem, which demands an effective treatment intervention. This Evidence-Based Practice project (EBP) addressed the question: Do patients with a psychiatric in-patient diagnosis of suicide ideation, who after discharge self-elect outpatient Cognitive Behavioral Therapy-Suicide Prevention (CBT-SP) treatment over a 6-week time frame, reduce the likelihood of hospital readmission for suicidal ideation vs. patients who decline CBT-SP treatment and elect Treatment as Usual (TAU)? The literature is prolific in validating that CBT-SP is successful in determining the effectiveness of CBT-SP vs. TAU in reducing suicidal behaviors in adults. Hospital readmission data were collected on both the CBT-SP and the TAU groups. The CBT-SP group collected a further measure utilizing the Quality of Life (QOL) Scale pre and post CBT-SP group intervention. Demographic variables of age, sex, and homelessness were compared to assess variability between the two groups. The CBT-SP and the TAU groups were compared for rehospitalization utilizing the Fisher Exact Test, which was statistically significant.
The Celestial Imagination: Proclus the Philosopher on Theurgy
Authors: Redondo José Manuel
Published: December 2020

This paper focuses on Proclus’s On the hieratic art of the Greeks – considered as a contemporary philosophical problem – exploring some of its fundamental concepts and images, thus delineating Proclus’s notion of theurgy, which he primarily conceived as divine action manifesting in the union between a god and the theurgist, and only secondarily as a technique. These aesthetic experiments of thought or philosophical performances, by means of which a divine self is created, had deep metaphysical, cosmological, psychological, ethical, linguistic and even political and religious implications for Late Antiquity Platonism, and had a profound impact on the development of Renaissance philosophy and magic. Such practices are meant to be understood in the context of the philosophical paideia of which it represents its final stage and consummation; they are developed by intricate hermeneutics of a poetic theology operated by very sophisticated conceptions of symbol, analogy and the imagination, all of which are at the base of the celestial-terrestrial correspondences used by theurgists in their hymn singing.
Investigating the Magical Practice found in PGM (Greek Magical Papyri) XIII
Authors: Chandler Claire
Published: December 2020

PGM XIII is a Greco-Egyptian magical papyri dated to the mid fourth century CE. It contains at least two versions of a rite to summon the creator god and gain his name, which is then used in further spells also included in the papyrus. This paper examines the practices involved in this rite and explores their theoretical underpinning, investigating timing, writing and symbolism to expose the interconnectedness implicit in the ancient worldview and the place of magic within it. The magical papyri are documents which reflect the methods and experience of actual magical practitioners rather than literary depictions. These accounts and methods contextualise magic within an ontological world view.
Alchemy and the Transgendering of Mercury
Authors: Warlick M. E.
Published: December 2020

Within late medieval alchemical texts, Latin authors adopted both classical and Arabic concepts of physical matter. They assumed that metals were composed of two polarized substances – hot, dry and masculine Philosophic Sulphur, and cool, wet and feminine Philosophic Mercury – whose ‘Chemical Wedding’ within the laboratory produced the Philosophers’ Stone. As visual illustrations developed in alchemical manuscripts and early printed books from the late fourteenth century onward, artists represented these substances with a variety of male and female characters, with Philosophic Mercury almost always depicted as a woman. At the same time, the planet Mercury, which oversaw the ripening of the metal Quicksilver within the earth, also played an important role within alchemical illustrations. This paper will examine how artists navigated this confusion by examining gendered images of the philosophical concept Mercury, the metal Mercury, and the planet Mercury, in light of shifting attitudes towards women in early modern science.
Astral Ascent in the Occult Revival
Authors: Godwin Joscelyn
Published: December 2020

The occult revival of the later 19th century inherited Neoplatonic and Hermetic ideas of astral ascent and commerce with the planetary spirits, but felt obliged to square these with contemporary discoveries in astronomy. In the 1850s, Andrew Jackson Davis adapted Swedenborgian ideas into a semi-scientific cosmology that served as the norm for spiritualists. In the 1870s, occultism separated from spiritualism and made its own pact with science, with results visible in the works of Emma Hardinge Britten, H. P. Blavatsky, and the Hermetic Brotherhood of Luxor. Outside these well-known movements, Cyrus Teed, known as Koresh, taught that the earth is a concave sphere with the heavenly bodies at the center. His system revived the themes of astral immortality through ascesis and an alchemical relation of humans to a closed cosmos. It was the basis for one of America's more successful utopian communities, which outlasted Teed for more than 50 years.
