Leaving, Again.
Authors: Alshammiry Areej
Published: September 2024

This short reflection with a photo is based on an emotional moment I had during my last visit to Kuwait, where I was born a third-generation stateless person, and later emigrated from to Canada, where I currently reside. It is an expression of the emotional and social manifestations of living between two countries and experiencing the loss of time with family and friends. It is an expression of the yearning for social connections that I left behind. It is also an attempt to reconcile with the experiences of forced migration and distance, which are not always successful.
 
I used to visit Kuwait annually, but when COVID-19 hit, it interrupted these frequent visits. Up until recently, I had not visited in four years. But I stayed connected with my family and friends virtually, though WhatsApp, Instagram, Twitter, Zoom. When I finally went this winter, I was filled with overwhelming emotions. It had been too long, and I felt as though things have changed. But it was really me who has. Being away for such a long time has created a gap that I am still trying to understand. I was never troubled by distance. In fact, I loved it because it gave me the space to learn more about myself and explore the world. I thought I was okay with the distance for the longest time. But I learned how much I was craving the warmth of close connections, the in-person quality time, the long night chats, the morning coffees, the brunches by the beach, and the hugs I received from loved ones. I leaned that this distance meant missing out on making memories with loved ones. And losing so much time that can never be regained.
 
I realized that when I was glued to my phone every day for hours, it was because I wanted to stay connected, and not be forgotten because distance can do that. I have already felt so many friendships fade away because of the distance, and now I find myself trying to hold on to those I have left. Yes, I made new ones virtually. And I had the chance to meet them in person this time. And it was beautiful. But now, I am leaving, again. I am more now of how this distance impacts me, and my relations. This time, I was very sad to leave.
 
I wasn’t ready to leave just yet. I did not get enough time to be with my loved ones. It was a month, but it felt so short. I tried to squeeze all the meetings, squeeze all the love I craved, but it was so much love that just didn’t fit in such a short time. I had to leave eventually, again, with a big part of my heart left behind. A big part of my life away from me. And no matter what I do to stay connected, it’s not the same. I realized now, no matter what I choose, where I choose to live, I cannot have it all. And that I will always be giving up something. Oh the luxury to have it all…

Published: September 2024

The progression and participation of women in senior management positions in Higher Education Institutions (HEIs) in South Africa have been limited despite progressive laws aimed at promoting gender equality. This study aimed to understand the inherent power structures which impede the progression of women to senior management positions in an Open Distance e-Learning (ODeL) institution. The Feminist Standpoint Theory was adopted as a lens and theoretical framework for framing the study. An Interpretative Phenomenological Analysis (IPA) was adopted as the research design for the study. Data were collected through semi-structured interviews with 25 participants, and the interviews were transcribed verbatim. A thematic data analysis was employed to analyse the data. The findings of the study revealed that the inherent power structures which impede the progression of women to senior management positions include patriarchal structures; acknowledgement of male leadership standards over women’s standards; gendered and stereotyped power structures; and non-compliance with gender equity constitutional stipulations. The study also showed the visible patriarchal features and reasons men progress to senior management. By and large, the findings emphasised the need for the ODeL institution to implement policies and laws that promote the progression of women to senior management positions.
Clinico-microbiological profile of urosepsis patients in a tertiary care hospital in India: A 1-year study
Authors: Prabhu Kavitha , Bhat Prasanna N. , Boloor Rekha , Shetty Anup Kumar , Nayak S. Ganesh , Sundarsingh Vijay
Published: September 2024

Objectives:

Urosepsis is a life-threatening bacterial infection resulting from a complicated urinary tract infection. Early diagnosis of urosepsis, its causative agent, and the susceptibility pattern are most important for accurate treatment to prevent mortality. Diagnosis includes recognition of the presence of sepsis and the investigations that help in the management of patients. The most common organism causing urosepsis is Escherichia coli, followed by other members of the Enterobacteriaceae family. With this background, this study was conducted to determine the clinical-microbiological profile of urosepsis patients in our tertiary care hospital.

Materials and Methods:

This was a prospective observational study; patients with clinical urosepsis and growing identical bacteria from both urine and blood cultures taken simultaneously are included in the study. The details of the clinical presentation and laboratory investigation results were recorded on an Excel sheet.

Statistical analysis:

Statistical analysis was done using IBM Statistical Package for the Social Sciences Statistics V.23. The categorical variables such as demographic, microbiological, and other laboratory characteristics and clinical outcomes were analyzed and expressed in terms of frequencies and percentages. Continuous variables were expressed in terms of median. Independent t-test, Mann–Whitney U-test, Chi-square test, or Fisher’s exact test were used wherever applicable.

Results:

We found 87 urosepsis patients in one year with a mortality rate of 22.98%. The mean age of the patients was 61.5 years, with majority (42.42%) above 65 years. Gram-negative bacilli were frequently isolated, with the highest number of E. coli (68.96%), followed by Klebsiella pneumoniae (20.68%). Sixteen (18.4%) of Gram-negative bacilli were Carbapenem-resistant Enterobacteriaceae. Multiple risk factors were seen in 58/87 (66.66%) patients, with diabetes mellitus as the most common risk factor.

Conclusions:

Urosepsis is a critical condition with a high mortality rate. Meropenem can be used as an empirical therapy with careful observation of patients in view of the occurrence of carbapenem resistance. A multidisciplinary team approach comprising intensive care specialists, urologists, radiologists, and microbiologists is very important for the effective and rapid management of urosepsis.

The Botanical Collection
Authors: Müller Frank
Published: September 2024

Describing plants and exploring their appearance, occurrence and usefulness have been common practice from antiquity. Even though the term “herbarium” underwent various changes in meaning over the centuries, it generally referred to a book on herbs, listing plants that were believed to possess pharmaceutical properties. Illustrations – some of them of high artistic quality – in books on herbs have been known since the Early Modern Period. Illustrative woodcuts created between 1530 and 1546, depicting the herbaria of the three pioneers of botany, Otto Brunfels, Leonhart Fuchs and Hieronymus Bock, had additional value as botanical reference points (Dressendörfer 2011). Nature printing, using the plant itself as the printing plate, was another method used in illustrating botanical books. It drew on the idea of nature inscribing itself to determine the technique of illustration. The rather elaborate procedure, described by Leonardo da Vinci and perfected during the 19th century, allowed for a detailed image of the plant in question.
The Medical-Historical Collection
Authors: Lienert Marina , Heidel Caris-Petra
Published: September 2024

Exhibits collected by the Duke of Weissenfels provided the basic stock for a larger collection of the Collegium Medico-Chirurgicum in Dresden. This was the first Saxon school of surgery, opening in 1748. It was succeeded by the Provisional Teaching Institute of Medicine and Surgery (1814/15) and the Surgical-Medical Academy (1815 to 1864). These institutions also made use of comprehensive collections in their training of military doctors, surgeons and medical practitioners. Unfortunately, none of these exhibits made it into the possession of the indirect successor institution, the Medical Academy “Carl Gustav Carus”, founded 90 years after the Surgical-Medical Academy closed. However, a physician interested in medical history began acquiring new objects for teaching purposes. Heinrich Fritz, head of the X-ray and Radium Institute of the Dresden-Johannstadt Hospital from 1948, then Professor of Radiology and Radiotherapeutics at the Medical Academy “Carl Gustav Carus” and Director of the Radiology Clinic, collected more than 20 different X-ray tubes, documenting the development of the relatively new discipline. They were on display in a purpose-built cabinet and were used in the training of medical students and medical technical assistants. Nevertheless, there seem to have been no systematic efforts at the new institution to collect material witnesses to medical history, despite the efforts of Heinz Egon Kleine-Natrop, a proven expert and promoter of Dresden’s medical history at the Medical Academy “Carl Gustav Carus”. Kleine-Natrop was the first Director of the Dermatological Clinic and full Professor of Dermatology from 1957. This lack of system when it came to acquiring historical exhibits was perhaps due to the proximity of two important institutions, both of which had been founded before World War I and already owned extensive medical history collections: the Karl Sudhoff Institute for the History of Medicine and the Natural Sciences in Leipzig and the “Deutsches Hygiene-Museum” in Dresden.
The Dye Collection

Published: September 2024

For thousands of years, coloring agents have been employed to dye textiles and other materials. Apart from the time-honored use of colors in many fields of design, research into colors has increased considerably as regards function and importance, particularly in recent years. The material witnesses associated with these processes have also found their way into the Dye Collection of the TUD Dresden University of Technology, one of the most comprehensive and significant collections of its kind in Europe. The inventory currently includes around 1,500 natural dyes of plant or animal origin, more than 20,000 synthetic dye samples and over 3,000 sample cards and books, as well as numerous samples of dyes prepared in the Institute of Colour Chemistry, the domicile of the Dye Collection. It also contains coal and tar products, various fiber materials, earth and mineral colors, and a collection of the Institute’s scientific papers and specimens from 1897 onwards. The Collection documents the development of color chemistry and the dye industry from the mid-19th century onwards and is still used today as a source of visual aids and as a reference work in teaching and for scientific purposes.
The Collection of Mathematical Models
Authors: Lordick Daniel
Published: September 2024

When scientists today talk of a mathematical model, they usually do not refer to objects such as those presented in this Collection, but to a formalized description − employing mathematical means − of a sub-problem from the world we experience. The more precisely an event is “modeled,” the better it can be predicted. Accurate weather forecasts, analyses of financial markets and the characterization of complicated processes from physics, chemistry and biology become possible when the power of computers is harnessed. Despite these obvious successes in almost all areas of life, despite their key role in advanced technology, and despite many attempts at mediation, mathematicians and the rest of society remain thoroughly divided: Their formalistic science is often regarded as incomprehensible and remote, not least because of its highly condensed language.
The Historical Acoustic-Phonetic Collection
Authors: Hoffmann Rüdiger
Published: September 2024

Machines that can talk and listen have been part of historical tradition since antiquity. Dresden also boasts one of the legendary “speaking heads”, which is said to have been made around 1700 by the versatile vice-rector of the “Kreuzschule”, Johann Valentin Merbitz. However, it was not until the Age of Enlightenment, under the influence of Leonhard Euler, that serious scientific attempts were made to build “speaking machines”. One of these, constructed by Wolfgang von Kempelen and described in 1791, has rightly become famous. Its creator presented it on one of his lecture tours in Dresden in 1784, and today a replica from 2009 enhances the Acoustic-Phonetic Collection of the TUD Dresden University of Technology. It was a long road, then, to the establishment of the field that is referred to today as natural language human-machine interaction or more simply as speech. Its development would not have been possible at all without the accompanying preliminary work in electronics and computer technology. At universities, the field was institutionalized in different ways, with its interdisciplinary nature rooted in very different disciplines, such as phonetics, physiology, perceptual psychology, acoustics, communications engineering, and computer science. In Dresden, speech technology emerged as part of weak current engineering. At present, this field is called information technology and has its own collection: the “elektron” Collection.

Для успешного развития бизнеса необходимо грамотное управление рисками, в том числе связанными с информационной безопасностью. При оценке рисков следует учитывать действия злоумышленников, среди которых выделяют внутренних и внешних. Зачастую действия внутренних злоумышленников, инсайдеров, оказывают наиболее пагубное воздействие на компанию (организацию). Основная опасность заключается в высокой осведомленности внутренних злоумышленников об уязвимостях в информационных системах (далее – ИС) компании (организации). Исследования в данной работе построены на аналитических данных ведущего производителя средств защиты информации InfoWatch. InfoWatch определила классификацию инсайдеров, но данная классификация инсайдеров не учитывает такой вид злоумышленника, как «конкурирующий инсайдер». В данной статье рассматриваются признаки «конкурирующего инсайдера» и влияние конкурентной борьбы на уровень информационной безопасности организации. Для выявления и противодействия злоумышленным воздействиям с разными видами инсайдеров предлагается метод, основанный на оценке эффективности работы персонала организации. Существующие программные методы выявления внутренних злоумышленников позволяют предотвратить утечку конфиденциальной информации, а предложенный метод позволяет выявить инсайдера на ранних стадиях подготовки злоумышленных действий.

For successful business development, it is necessary to properly manage risks, including those related to information security. When assessing risks, the actions of attackers should be taken into account, among which internal and external are distinguished. Often, the actions of internal attackers, insiders, have the most detrimental effect on the company (organization). The main danger lies in the high awareness of internal attackers about vulnerabilities in the information systems (hereinafter – IS) of the company (organization). The studies in this paper are based on the analytical data of the leading manufacturer of information security tools InfoWatch. InfoWatch has defined a classification of insiders, but this classification of insiders does not take into account such a type of intruder as a «competing insider». This article discusses the signs of a «competing insider» and the impact of competition on the level of information security of an organization. To identify and combat malicious influences with different types of insiders, a method based on evaluating the effectiveness of the organization’s personnel is proposed. Existing software methods for detecting internal intruders can prevent the leak of confidential information, and the proposed method allows you to identify insiders in the early stages of preparing malicious activities.

This paper offers a detection probability calculation model of the main obstacles that impede the taking off and landing of helicopters, specifically electricity power lines, in adverse weather conditions (at nighttime and/or in fog or snowfall) by means of modern, high-sensitivity thermal imaging devices, notably staring devices. An engineering method of predicting the thermal contrast of these lines sighted against the earth surface or the sky has been developed; numerical estimates of this contrast under various elevation angles of the power lines and the corresponding probability of their detection have been made. This method takes into account the temperature contrast of the lines and the surrounding air caused by electric current in the lines, temperature stratification of the atmosphere, and the thermal radiation of the surrounding area and the sun, as well as the difference in emissivity of the earth background and the surface of the lines in various spectral working band of the devices. Concrete calculation results are provided as well.

Определены условия спонтанно изменяющейся, априори неописанной воздушной среды, в которых целесообразно использовать нечеткие алгоритмы управления полетом автономного беспилотного летательного аппарата к заданному участку местности. Предложены инструментальные средства позволяющие сравнивать между собой нечеткие значения переменных состояния рулей управления полетом летательного аппарата и возмущающих факторов воздушной среды в процессе выбора импликативного решающего правила нечеткого алгоритма управления, содержащего результативное управляющее воздействие. Разработаны два способа повышения точности нечетких алгоритмов управления, существенным образом расширяющие возможности их эффективного применения для управления поведением сложных автономных объектов в нестабильных условиях проблемной среды с высоким уровнем неопределенности.

The conditions of a spontaneously changing, a priori undescribed air environment are determined, in which it is advisable to use fuzzy algorithms for controlling the flight of an autonomous unmanned aerial vehicle to a given area of the terrain. The tools are proposed that allow comparing the fuzzy values of the state variables of the flight control surfaces of the aircraft and the disturbing factors of the air in the process of choosing the implicative decision rule of the fuzzy con-trol algorithm containing the effective control action. Two methods have been developed to improve the accuracy of fuzzy control algorithms, significantly ex-panding the possibilities of their effective application to control the behavior of complex autonomous objects in unstable conditions of a problematic environment with a high level of uncertainty.

Коллекция представителей рода Rosa L. существует в составе коллекционного фонда ГБС РАН более 60 лет. За весь период интродукционных исследований был испытан 41 сорт, относящийся к группе мускусные гибриды. Изученные сорта представляют селекционные достижения трех стран-лидеров в мировой селекции мускусных роз (Германия, Англия, Бельгия). По количественным показателям традиционно преобладали сорта немецкой селекции. За период c 1958 по 2016 гг. на базе коллекции ЛДР ГБС РАН прошли интродукционные испытания селекционные достижения 10 оригинаторов. При этом преобладали сорта селекционеров, представляющих различные страны и направления селекционной работы (Lens, Pemberton, Kordes), создавших основу современного мирового сортимента мускусных роз. В ГБС РАН были испытаны сорта мускусных гибридов, созданные в разные периоды селекции, в целом охватывающие промежуток микроэволюционного развития культуры, составляющий около 100 лет (1910-2009 гг.). Подобная тенденция сохранена и в современной коллекции. С использованием сортов из ее состава спроектированы 3 варианта цветочных композиций, сориентированных на различные объекты ландшафтной архитектуры.

The collection of representatives of the genus Rosa L. has existed as part of the collection Fund of the Russian Academy of Sciences for more than XX years. During the entire period of introduction studies, 41 varieties belonging to the musk hybrids group were tested. The studied varieties represent the selection achievements of three leading countries in the world selection of musk roses (Germany, England, Belgium). In terms of quantitative indicators, German varieties have traditionally prevailed. During the period from 1958 to 2016, on the basis of the collection of LDR GBS RAS, 10 originators ‘ selection achievements were introduced. At the same time, varieties of breeders representing different countries and areas of selection work (Lens, Pemberton, Kordes) prevailed, creating the basis of the modern world assortment of musk roses. The GBS RAS tested varieties of musk hybrids created in different periods of selection, generally covering the period of microevolutionary development of the culture, which is about 100 years (1910-2009). This trend is preserved in the modern collection. Using varieties from its composition, 3 variants of flower compositions were designed, oriented to various objects of landscape architecture.
