2020 Pennsylvania Patient Safety Reporting: An Analysis of Serious Events and Incidents From the Nation's Largest Event Reporting Database
Authors: Kepner Shawn , Jones Rebecca
Published: April 2021

Pennsylvania is the only state that requires acute healthcare facilities to report all events of harm or potential for harm. With over 3.9 million acute care event reports, the Pennsylvania Patient Safety Reporting System (PA-PSRS) is the largest repository of patient safety data in the United States and one of the largest in the world. Of the 278,548 patient safety event reports submitted by Pennsylvania’s acute care facilities in 2020, 97.2% were from hospitals and 2.7% were from ambulatory surgical facilities (ASFs). The remaining 0.1% were from birthing centers and abortion facilities.

The vast majority of the 2020 reports were Incidents (97.0%) rather than Serious Events (3.0%). For each of the last five years, the most frequently reported event type was Error Related to Procedure/Treatment/Test, accounting for 32.1% of all submitted acute care event reports in 2020. The second, third, and fourth most frequently reported event types were Medication Error, Complication of Procedure/Treatment/Test, and Fall, accounting for 16.7%, 16.2%, and 11.8% of submitted reports in 2020, respectively.

The reporting rates for hospitals in Q1 and Q2 2020 were 32.8 and 31.5 reports per 1,000 patient days, respectively. For ASFs, the reporting rates for Q1 and Q2 2020 were 9.8 and 8.4 reports per 1,000 surgical encounters, respectively.

Published: April 2021

With the continuous development of artificial intelligence, the demand for sensors with simple preparation and strong concealment continues to increase. However, most of the high-sensitivity sensors have complex manufacturing methods, high costs, and single functions. In this paper, a sensitive motion sensor based on the triboelectric interaction between a living plant and the human body was designed to detect the real-time movements of human beings and provide danger warning. A certain relationship exists between the triboelectric signal and the distance between the plant and the human body, with effective signals being detected in the range of 1.8 m. In addition, the triboelectric signal generated by each person is unique like a fingerprint, which can be used for biometrics. On the basis of the triboelectric signal, a wireless character entry warning system is designed. This sensor can not only send out a wireless warning signal at a specific distance but also allow one to receive the warning information synchronously on a mobile phone in real time. The wireless movement sensor receives signals through a living plant, and it has the characteristics of convenient use, strong concealment, and shielding difficulty. This sensor has the potential to be widely used in person recognition, danger warning, and motion monitoring.

Published: April 2021

The objective of this article is to present the development of a smart alarm prototype that will help prevent bicycle theft in Oaxaca City, which is based on a programmable system. The project arises as a need for protection and safety of the bicycle as a means of transportation; since the thefts of bicycles parked on streets in Oaxaca City increase day by day. As, for example, Carrera (2018) notes that the responsible authority does not have a decisive participation in the abatement of bicycle thefts and that it is the citizens who seek them out by their own means and they not always get success. The research was carried out in two phases, in this document the first phase is presented, in which two functional prototypes of the smart alarm were designed and implemented. The applied development methodology is that of prototypes; since this facilitates the understanding of the needs of the users. With the present research, it is hoped to lay the foundations to continue with the improvement of the prototype and in this way, society will be offered an option to protect its heritage.

Published: April 2021

We developed SrSiO3:Ce crystals with different dopant concentrations of 0.5%, 1.0% and 2.0% using the floating zone method and investigated the scintillation and storage luminescence properties. Under X-ray irradiation, a broad emission band peaking at around 360 nm was observed in all the samples. The decay time constants were in the range of 33–34 ns, which were typical values for the 5d–4f transitions of Ce3+. The 1.0% and 2.0% Ce-doped samples showed a photoabsorption peak under 241Am 59.5 keV γ-rays and the light yield was 1200 and 1400 ph MeV−1, respectively. The results of pulse-height spectra and thermally-stimulated luminescence showed a complementary relationship between scintillation and ionizing-radiation-induced storage luminescence properties in Ce-doped SrSiO3.

Fracture neck of femur which are displaced, do not nd a place in the elderly where the head can be preserved even if there is a surgical intervention.
Fixation devices like the DHS have time and again failed to satisfactorily treat these fractures. It's here that the Bipolar Hemi Arthroplasty comes to
us, as a very handy operative tool. The question is, whether or not the stem of the Bipolar, be cemented or not. The problems of cementation in the
elderly carries the risk of BCIs – the bone cementing implantation Syndrome; which can at times be fatal. Cementation makes, future needed Total
Hip Replacement, more difcult. In this prospective study of patients conducted at Chettinad Hospital and Research Institute, Kelambakkam,
South India ; we have chosen an age group between 61 to 75 years, with an inclusion criterion satisfying type III or IV Garden, but also at the same
time, be classiable, as a type A or type B DORR's classication. Our male to female ratio was 1:2 the mean age was 68.5 years and 93.3% (n=84) of
patients undergoing un-cemented Hemi-Arthroplasty, when graded by HHS were either Excellent or Good. We had no Poor outcomes in our study.
Our minimum follow up was for 12 months, with a mean follow up of 23.5 months. All our cases were done by the Southern Moore's approach, with
an average duration of surgery at 82 minutes. The blood loss on an average was 285 ml and the average blood transfusion rate was at 1.8 units. The
average post operative stay was for 12 days. From this short-term prospective study, we concluded that Un-Cemented Hemi-replacement
Arthroplasty gives Good to Excellent clinico-functional outcomes. It also does not cause any hindrance, if future Total Hip Replacement, is
required. Our complication rates were also manageable, with only about 6.7% (n=6) patients, needing revision surgery due to stem loosening.

Published: April 2021

Water stress negatively affects productivity in crops, while the foliar application of potassium-containing compounds may be helpful in reducing the drought effects. This study evaluated the efficacy of foliar applied potassium chloride (control - distilled water spray -, 3 and 6 mM-1) on tomato plants under drought stress. Three irrigation levels were maintained at 100, 75 and 50% according to evapotranspiration designated as well watered, moderate and severe drought stressed. Increasing drought stress significantly reduced plant growth and yield. The foliar applied KCl produced maximum leaf area, stem diameter and length, plant yield under each drought stress conditions compared to control. The minimum of growth factors were obtained by control under severe stress. Highest yield per plant was also recorded for foliar applied KCl under moderate condition than other treatments. Foliar applied KCl alone decreased the SOD, CAT and PPO in well-watered condition but KCl application on tomato plants under drought stress induced the antioxidant enzyme activities more than control well-watered treatment.

Published: April 2021

The broad objective of this research is to study the effect of warm stratification on Cycas revoluta zygotic embryos length, seed germination and plant development. Four warm treatments were applied to seeds. Our results showed that seeds storage at room temperature or 30°C improved significantly zygotic embryos length. Moreover, time of germination was significantly reduced with the warm stratification. The highest percentage of germination was obtained with seeds warm treated at 30°C for 2 months while only 25% of seeds were able to germinate in the control. Regarding seedlings development, our results demonstrated that warm stratification did not affect plant development. No significant differences have been recorded in all the evaluated parameters except for root length. Taken together, these results underlined the beneficial effect of warm stratification on Cycas revoluta seed germination and plant development and proposed a new method to improve seed germination of Cycas revoluta.

Authors: Aydin Mesut , Ozer Serhat , Dirik Yaren , Dulger Ahmet Cumhur
Published: April 2021

Objective: Helicobacter pylori infection is a well-established risk factor for gastric cancer, which is more common in developing countries where poor sanitation and domestic overcrowding are common. We tried to analyze the impact of the pandemic on Helicobacter pylori infection during COVID 19 related curfew and stay-at-home order.

Material and Methods: Between 1-30 June 2020 (during stay-at-home order), a total of 172 dyspeptic patients who underwent upper gastrointestinal system endoscopy at our institution following stay-at-home order during COVID pandemic were included in this study along with a control group covering 192 dyspeptic patients who underwent endoscopy between 1-20 June 2019.

Results: When we analyzed gastric biopsy specimens, those who faced stay-at-home order had similar rates of intestinal metaplasia (22% versus 29%; p=0.15) and atrophic gastritis (24% versus 29%; p= 0.396) compared to recent year's data. On the other hand, the rate of H.pylori infection was higher compared to pre-COVID period (59% vs. 46%, p<0.05).

Conclusion: Domestic overcrowding during COVID 19 related stay-at-home order is a risk factor for H.pylori infection.

Published: April 2021

Given current global crises, there is a need to move beyond the anthropocentric, reductionist and short-term vision of the world, imposed through the hegemony of Western culture. Are we still in time to change the prevailing hegemonic vision of the world and better address global crises and their local impacts? What is the role of intercultural higher education in this challenging task? We conceive this type of education for the training of future decision-makers, as well as scientists and technicians who must respond to current and future challenges in society. Therefore, we evaluate the contribution of the Indigenous Peoples Program (PPI) of the Faculty of Physical and Mathematical Sciences (FCFM) at Universidad de Chile (UCH). We conclude that the PPI opens up possibilities for intercultural training in the FCFM, which can contribute to changing the professional and scientific performance of its graduates, opening their minds to other cultures, worldviews, values and paradigms.

Against Balancing: Revisiting the Use/Regulation Distinction To Reform Liability and Compensation Under Investment Treaties
Authors: Bonnitcha Jonathan , Aisbett Emma
Published: April 2021

Investment treaties generate mutual benefits for host states and foreign investors to the extent that they discipline opportunistic conduct by host states. Investment treaties do not necessarily generate mutual benefits insofar as they constrain states’ ability to respond to new information or to change their policy priorities. In a companion paper, we use the tools of law and economics to formalize and clarify the relationship between problems of opportunism on the one hand, and new information and shifts in policy priorities on the other. On this basis, we develop a proposal to reform the legal principles that govern liability and compensation under investment treaties that is narrowly targeted to solving the problem of host state opportunism.

In this paper, we situate our proposal in relation to existing academic debates, explore its implications in practice and consider additional policy arguments for our proposal beyond the criterion of Pareto improvement deployed in our companion paper. In particular, we show that our proposal develops a line of scholarship which posits that a court or tribunal should distinguish government use of private property from government regulation of private property, with only the former requiring compensation. We argue that our proposal resolves many practical challenges with previous attempts to develop a workable jurisprudence based on the use/regulation distinction and show how our proposal could be operationalized in practice. We further argue that there are strong political economy and democratic arguments for preferring our proposal to the status quo.
The Social Integration of Hindu and Muslim Communities: The Practice of "Menyama-Braya" in Contemporary Bali
Authors: Arjawa I Gst. Pt. Bagus Suka , Zulkifli Zulkifli
Published: April 2021

The social interaction between Bugis Muslims and Hindus in Bali has long been known to be harmonious. This interaction can become a role model for religious interaction in Indonesia. This paper aims to explain the practice of menyama-braya (brotherhood) as a cultural system and its relevance to the integrative social interaction between the Hindu and Bugis Muslim communities in Bali. The research was conducted in the villages of Serangan, Kepaon, Tuban, Suwung, Tanjung Benoa, and Angantiga. The research is qualitative in nature and draws on interviews and the broader literature. The study reveals that a successful harmonious social life cannot be separated from the adoption of menyama-braya culture, which combines the attitude of solidarity and tolerance. The practice of the menyama-braya cultural system has been maintained for generations through various methods, such as socialization, rituals, the use of the same symbols, and formal educational institutions.
The Predicaments of Muslims in the Philippines: An Exposition of Said Nursi’s Hypothesis vis-à-vis Hizmet Movement Approach
Authors: Cayamodin Jamel Rombo , Durakoglu Abdulhamit
Published: April 2021

The complexities of interdependent predicaments experienced by Muslims propel their pessimism on the prospect of reform in the Philippines. This pessimism has made the apathy of Muslims towards the corrupt system in the country. Consequently, this condition drives the weakening of altruism and increases apathetic social identifiers. These predicaments continue until the current day due to the lack of inclusive and effective remedies for improving the rudiments of people’s living in contemporary society. By using analysis of documents and in-depth interviews, the writers examine the root causes of Muslim-Filipinos’ interdependent predicaments according to Said Nursi’s hypothesis vis-à-vis Hizmet Movement approach. The study finds that Said Nursi’s “triumvirate quandaries hypothesis” resembles, to a greater extent, the interdependent predicaments of Muslims in the Philippines. Thus, inclusive remedies concurrent to the approaches of the Hizmet Movement that are known to have effectively addressed the triumvirate quandaries need to be contextualized in the Muslim-Filipino society within the context of the Philippines secular state.
Voices from Indonesian Legislative on Religious Education Policy

Published: April 2021

Religious violent extremism remains a problem for Indonesia. Recently, three consecutive attacks carried out by violent religious extremists — a suicide bombing in front of a Cathedral Church in Makassar South Sulawesi, the discovery of several prepared high explosive bombs in Condet Jakarta, and a female lone wolf attack on the Indonesian Police Criminal Investigation Agency — shocked the public (Fakta-data di Balik Bom Bunuh Diri, 29 Maret 2021; Polisi sebut Terduga Teroris Condet & Bekasi, 2021; Teroris Penyerang Mabes Polri, 2021). It may not be surprising since there were some early indications from various studies that some Indonesian people still have religious attitudes and behaviors that are exclusive, closed, anti-citizenship, anti-state, and even pro-violence (PPIM, 2016, 2017, 2018; Puspidep, 2017, 2018). The PPIM study results (2018) show that around 58.5 percent of students tend to be religious radical, and 51.1 percent tend to be intolerant to differences within Muslim groups. Then, as many as 34.3 percent of students are intolerant to non-Muslim groups. Radical views that are intolerant toward those who are different are the first step to violent extremism. These studies are a reminder that violent extremism is a problem for all of Indonesian society. Therefore, PPIM surveyed the perceptions of the public, students, teachers, and Indonesian Members of Parliament on violent extremism.
Translation quality in English-Arabic translation of tourist texts: A product perspective
Authors: Qassem Mutahar , Ali Lamis , Muhayam Nabil
Published: April 2021

Translation of tourist texts engenders textual, linguistic and cultural hurdles before achieving translation quality, which has not been given due account in translation studies. To bridge this gap, this study aimed to assess postgraduates' performance in translation of tourist texts from English to Arabic and vice versa, using a translation task (Arabic and English tourist texts) and a questionnaire. The questionnaire took a form of a 5-point Likert scale in which the students rated the texts they translated. Further, it retrieved information about translation time and postgraduates' translation experience. Findings revealed low translation quality and inappropriate use of translation procedures in rendering the tourist texts into English and Arabic. The postgraduates encountered hindrances in formulating the main ideas of the source text (ST), composing the target text (TT) and communicating the TT to the target language (TL) readers. Based on the findings, pedagogical implications have been discussed.
A Marxist Reading of Mariama Bâ's So Long a Letter
Authors: Abdulkadir Hamzat
Published: April 2021

This work examines Mariama Bâ's So Long a Letter from a Marxist perspective. It explores the radical and feminist tendencies on the stereotype of African women with the awareness that women are equal with men without prejudice to the interpretation of the theory of creation. Based on Marxist theoretical framework, our analysis shows that the oppression and exploitation of women is a process involving women themselves. The woman, in effect, continually reproduces the conditions of her subservience as Marx will add, through alienation, competition, rivalry and docility. Through alienation, women forfeit their rights to be the initiators and controllers of their historical processes. The study concludes that Marxist Feminist must practically engage in struggle against inequality and all manifestations of oppression and exploitation of women.

Published: April 2021

The synthesized nanomaterials by two different methods were used as a catalyst in the transesterification
of waste cooking oil to produce biodiesel. For both environmental and economic reasons, it is beneficial to produce biodiesel from waste cooking oils. It is desirable to help solve waste oil disposal by utilizing its oils as an inexpensive starting material in biodiesel synthesis. The structure, morphology, and surface properties of resulting nanocatalysts were characterized by X-ray Fluorescence Spectroscopy (XRF), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), Energy Dispersive X-ray Spectroscopy (EDX) and N2 adsorption-desorption isotherms. The synthesized nanocatalysts' efficiency in
the production of biodiesel was studied by Gas Chromatography (GC) as well as leaching amounts of surface active components of each catalyst investigated by the EDX technique. The reactions were performed at 65°C using a 9:1 methanol to oil ratio for 3 h. The results indicate that the impregnated mixed metal oxide catalyst ( Ca-MgAl) shows a higher surface area and better mechanical strength than the totally co-precipitated mixed metal oxide catalyst (CaMgAl(O)). Although both of the fully co-precipitated and impregnated catalysts represented about 90% of fatty acid methyl esters (FAME) yield the leaching of active calcium component was significantly reduced from 45.8% in precipitated CaMgAl(O) to 8% for the impregnated Ca-MgAl catalyst. This improved structure represents the advantage of the impregnation technique to co-precipitation procedure for fabrication of robust nanostructures.

From the depths of his self-imposed isolation, Alexander Grothendieck has sent us a vast, introspective work: Récoltes et Semailles (Crops and Seeds). Mathematician Pierre Cartier, one of Grothendieck’s colleagues, offers a rational and honest appraisal the work and the man.
Interstellar Science
Authors: Luminet Jean-Pierre
Published: April 2021

The film Interstellar draws heavily from contemporary science. It makes reference to a range of topics, from established concepts such as fast-spinning black holes, accretion disks, tidal effects, and time dilation, to far more speculative ideas such as wormholes, time travel, additional space dimensions, and the theory of everything. Jean-Pierre Luminet examines how these topics were depicted.
