Changes in interdental papillae heights following alignment of anterior teeth
Authors: Kandasamy Sanjivan , Goonewardene Mithran , Tennant Marc
Published: December 2023

Background

Orthodontic alignment of overlapped incisors can reduce the apparent heights of the interdental papillae leading to unsightly dark triangles or open gingival embrasures.

Aim

To determine if certain pretreatment contact point relationships between the maxillary anterior teeth were accompanied by changes in the heights of the interdental papillae after orthodontic alignment.

Methods

Pre- and post-treatment intra-oral 35 mm slides, lateral cephalometric radiographs and study casts of 143 patients (60 males, 83 females) between 13 and 16 years of age were used. The patients had diastamata closed, imbricated teeth aligned and palatally or labially placed teeth repositioned. A sample of 25 patients (12 males, 13 females) between 13 and 16 years of age who had well-aligned anterior teeth at the start of treatment acted as a control group. All patients were treated for approximately 18 months. The clinical crowns of the maxillary incisors and the heights of the interdental papilla between the incisors were measured on projected images of the slides. The percentage increases or reductions in the heights of the interdental papillae were compared.

Results

The heights of the interdental papillae increased following palatal movement of labially placed (p < 0.05) or imbricated (p < 0.05) incisors and the intrusion of one incisor relative to an adjacent incisor (p < 0.01). The heights of the interdental papillae reduced following labial movement of an imbricated (p < 0.05) or palatally placed (p < 0.05) incisor or closure of a diastema (p < 0.01). Before treatment the midline papillae in the diastema subgroup were of similar length to the midline papillae in the control group, but after treatment they were markedly shorter. The interdental papillae associated with crowded or imbricated incisors were shorter than the interdental papillae in the control group before and after treatment.

Conclusions

Dark triangles are less likely to develop following palatal movement of labially placed or imbricated teeth and the intrusion of one tooth relative to another. On the other hand, dark triangles are more likely to develop following labial movement of imbricated or palatally placed incisors and closure of a diastema. Clinicians should be alert to the possibility of dark triangles developing in the latter group, particularly in older patients.
Static frictional resistances of polycrystalline ceramic brackets with conventional slots, glazed slots and metal slot inserts
Authors: Jones Steven P. , Amoah K. Gyaami
Published: December 2023

Aims

To compare the static frictional resistance of ceramic brackets with a conventional slot (Allure), a glazed slot (Mystique) and a metal slot insert (Clarity).

Method

Twenty five brackets of each type, with slot size 0.022 x 0.028 inch and Roth prescription were tested by sliding against straight lengths of 0.019 x 0.025 inch rectangular stainless steel wire. During the tests the brackets and wire were lubricated with artificial saliva. Static frictional forces at three different simulated binding angulations (0, 5 and 10 degrees) were measured for each type of bracket.

Results

At each of the angulations tested, the Clarity brackets produced the lowest static frictional resistance. At 0 degree angulation (below the critical angle for binding) the Allure brackets produced the greatest friction. The difference in friction between the Clarity and Mystique brackets was not statistically significant. As the angulations were increased to 5 degrees the Allure brackets again produced the greatest frictional resistance, although this was not significantly higher than the Mystique brackets. The Mystique brackets produced the greatest frictional resistance at 10 degrees, but again there was no statistical difference from the Allure brackets.

Conclusions

A glazed slot ceramic bracket demonstrates low frictional resistance at non-binding angulations and compares favourably with a metal slot ceramic bracket. Increasing angulations through 5 to 10 degrees of simulated binding results in high levels of static frictional resistance such that the bracket behaves more like a conventional polycrystalline ceramic bracket.
Use of the AHP Method for Preference Determination in Yacht Design
Authors: Sierzputowski Jan , Karczewski Artur , Krata Przemysław
Published: December 2023

A sailing yacht is a human-centred product, the design of which revolves primarily around the wants and desires of the future owner. In most cases, these preferences are not measurable, such as a personal aesthetic feeling, or a need for comfort, speed, safety etc. The aims of this paper are to demonstrate that these preferences can be classified and represented numerically, and to show that they are correlated with the type of yacht owned. As a case study, the owner’s preferences for deck equipment are considered. These are determined by pairwise comparisons of the importance rankings for features previously defined by yacht owners, following the analytic hierarchy process (AHP) method. As a result, a quantitative representation of these preferences is established, and they are shown to be correlated with the type of yacht. The findings of the current study show that the yacht owners’ preferences can be represented numerically, leading to a utilitarian conclusion that concerns the support and even some degree of automation of the design process.
Analysis of the Environmental Impact of the Hull Construction of a Small Vessel Based on LCA
Authors: Nakielski Jacek
Published: December 2023

In recent years, issues related to the impact of human activity on the natural environment have become pressing, and the challenge of global warming necessitates immediate action. To support environmental protection efforts, it has become imperative to adopt a broader perspective when evaluating various products and systems. A valuable tool for such assessments is a life cycle assessment (LCA), which enables a comprehensive analysis of the entire life cycle of a product.

This paper presents a comparative analysis of the hull of a fast patrol craft, fabricated using three different materials: steel, aluminium, and composite materials. The LCA covers every stage from material production, through the construction and use of the hull, to its eventual disposal. A specific criterion was established to evaluate the impact of the hull on the environment, with clearly defined system boundaries.

In the final section, we draw some conclusions that underscore the importance of reusing construction materials. By emphasising this approach, ecological footprints can be minimised and a sustainable future can be created.
Effects of Propeller Fouling on the Hydrodynamic Performance of a Marine Propeller
Authors: Zinati Ali , Ketabdari Mohammad Javad , Zeraatgar Hamid
Published: December 2023

Propeller performance is typically considered under clean conditions, despite the fact that fouling is an inevitable phenomenon for propellers. The main objective of this study is to investigate the effects of roughness due to fouling on the performance of a propeller using a CFD simulation in conjunction with the roughness function model. A simulation of a clean propeller is verified for a five-blade propeller model using existing experimental results. A roughness function model is then suggested based on existing measured roughness data. The simulations are extended for the same propeller under varying severities of roughness. Initially, it is concluded that KT and ηo gradually decrease with increasing fouling roughness, while KQ increases, compared to smooth propeller. For instance, at J=1.2 for medium calcareous fouling, KT is reduced by about 26%, KQ increases by about 7.0%, and ηo decreases by 30.9%. In addition, for the rough propeller, the extra power required is defined as the specific sea margin (SSM) to compensate for the power loss. A slight roughness causes a large decrease in ηo. A propeller painted with foul-release paint and an unpainted propeller are found to require 2.7% SSM and 57.8% SSM over four years of service, respectively. Finally, the use of foul-release paints for propeller painting is strongly advised.
Quantumness in Diagnostics of Marine Internal Combustion Engines and Other Ship Power Plant Machines

Published: December 2023

The article provides proof that the diagnostics of marine internal combustion engines and other ship power plant machines should take into account the randomness and unpredictability of certain events, such as wear, damage, the variations of mechanical and thermal loads, etc., which take place during machine operation. In the article, the energy E, like the other forms (methods) that it can be converted into (heat and work), is considered the random variable Et; at time t, this variable has the mean value

, irrespective of the functional form of the random variable Et. A proof is given that shows that the expected value estimated in the above way, considering the time t of the performance of task Z by a marine internal combustion engine or other ship power plant machine, can be used to determine the machine’s possible action (DM). When compared to the required action (DW) needed for task Z to be performed, this possible action makes it possible to formulate an operating diagnosis concerning whether the engine or machine of concern is able to perform task Z. It is assumed that an energy device of this type is able to perform a given task when the inequality DM≥DW holds. Otherwise, when DM < DW, the device cannot perform the task for which it was adopted in the design and manufacturing phase, which means that it is in the incapability state, although it still can be started and convert energy into the form of heat or work..

Published: December 2023

This research explores into the comprehensive examination of resource management strategies employed by hotel managers, with a specific focus on committed resources and their impact on cost behavior. This study aims to determine the cost behavior of The RBS Hotel during the the COVID-19 pandemic. This study employs a qualitative descriptive research design, and utilizing interview and observation methodologies. The findings of the study indicate that managers implemented diverse tactics to facilitate cost changes, which subsequently influenced the cost behavior of hotels. The onset of the COVID-19 pandemic resulted in a shift in the behavior of hotel costs during its initial year. There has been a decrease in both employee salaries and routine maintenance costs. The non-routine maintenance tasks experienced an upward trend during the pandemic. All three exhibit characteristics of semi-fixed cost behavior. The costs associated with room facilities are subject to variation, but with a downward trend. This study makes theoretical contributions to the fields of cost behavior theory and upper echelon theory.

Technical Efficiency and Intellectual Capital Islamic Banks in Indonesia
Authors: Hidayati Irma , Nandiroh Umi
Published: December 2023

This study explores the impact of intellectual capital on the technical efficiency of Islamic banks in Indonesia, emphasizing the shift from traditional physical assets to intellectual resources like digital systems, technologies, and brand value. It analyzes nine Islamic banks out of fourteen in Indonesia from 2013 to 2022 using a two-stage data analysis method. The first stage involves the Data Envelopment Analysis (DEA) model to measure technical efficiency, while the second stage uses the fractional regression model (FRM) instead of the traditional Ordinary Least Squares (OLS) method. The research introduces the iB-VAIC coefficient as a new intellectual capital metric. DEA results show that the average efficiency score for Indonesian Islamic banks is 0.945, with only two banks achieving a perfect score. The FRM analysis indicates a significant link between intellectual capital (iB-VAIC) and technical efficiency, with different components of intellectual capital having varied impacts. The study finds a negative correlation between bank size and technical efficiency and provides insights for bank management and policy development in Islamic banking.

Ciudadanías migrantes: clientelismo y corrupción en la correspondencia de trabajadores agrícolas temporales
Authors: Córdoba Ramírez Diana Irina
Published: December 2023

La indagación que ofrecen estas páginas repara en la correspondencia que produjeron los aspirantes a un contrato como braceros para incidir en las contrataciones. El análisis cualitativo arroja luz sobre los complejos controles políticos y sociales de la ciudadanía, pero también sobre las oportunidades enlazadas con el ser ciudadano en migración. En un plano alterno al de las definiciones, la normatividad y las regulaciones, la forma como los individuos se apropiaron del concepto y los derechos que acompañan esta categoría es de enorme interés para la comprensión del orden político que prevaleció durante el Programa Bracero. De aquí que este trabajo se incline por la descripción, análisis y compresión de narraciones que entretejen la noción de ciudadanía y patriotismo por parte de individuos en migración. La correspondencia muestra el diálogo de los aspirantes con las estructuras formales que se diseñaron para la operación del programa, su negociación con espacios de poder que fueron más allá de la agenda binacional, la formación de una cultura política que adoptó los parámetros de la petición decimonónica y la relación clientelar que -ya observada en el siglo XIX- se institucionalizó para las clases populares por la política de la modernidad posrevolucionaria.
Actividades económicas que afectaron a la seguridad y salud pública en la capital del Virreinato del Perú y la tentativa de solución a mediados del siglo XVIII
Authors: Rivasplata Varillas Paula Ermila
Published: December 2023

Las actividades productivas contaminantes como tenerías, curtidurías, carnicerías y rastros solían estar cerca a los cursos de agua, las acequias e incluso al río Rímac y a la Plaza Mayor de la ciudad de Lima, impactando negativamente la imagen de la capital, sede del virreinato del Perú, y la salud de los vecinos. En la segunda mitad del siglo XVIII, las autoridades ilustradas ordenaron la reubicación de las actividades económicas que generaban basura y ensuciaban el agua en las periferias de la ciudad. Sin embargo, la resistencia de los dueños hizo lenta la aplicación de la ley y provocó que el centro de la ciudad continuara siendo un foco latente de propagación de pestes.
Ningún taller. Experimentaciones desde el taller artístico dentro de la institución penitenciaria
Authors: Hoyos Gonzalez Pablo
Published: December 2023

El artículo reflexiona en torno al rol de la educación y los talleres artísticos en el sistema penitenciario de México. Esto desde dos experiencias de experimentación colaborativa con personas privadas de la libertad en dos reclusorios de la Ciudad de México. A partir de la performance del “tallerista sin taller” se propuso experimentar con la forma del taller artístico vaciándolo de su marco disciplinar y pedagógico, intentando llevarlo a una situacionalidad donde el taller pudiera ser ningún taller. Daremos cuenta del diseño metodológico del ningún taller desde la performance, así como de sus implicaciones éticas a partir de la exposición de dos experiencias concretas: La vida no decide sola (2014) y Repensando el Estado Penal (2018). Finalizamos con una reflexión sobre las características de la “okupación” situacional del taller cultural, concluyendo que se debe a la intervención de la temporalidad y no tanto con la intervención del espacio penitenciario.
La Escuela Normal Rural del Istmo de Tehuantepec en Comitancillo, Oaxaca (1929-1935)
Authors: Sigüenza Orozco Salvador
Published: December 2023

En México, el gobierno de la post revolución impulsó la creación de normales y escuelas campesinas para formar maestros que trabajaran en las zonas periféricas del país, sobre todo rurales e indígenas. En ese contexto, el artículo expone el proceso de fundación y funcionamiento de una escuela normal en el Istmo de Tehuantepec, Oaxaca, en los años 1929-1935. A partir del análisis de documentos originales, se plantean los criterios para el establecimiento de la institución, sus objetivos y tareas encomendadas, fundamentalmente de carácter social. Se señalan sus principales actividades y dificultades de funcionamiento, así como información relativa al personal docente y alumnos.
Si bien el texto aborda el periodo formativo de una institución en la que se formaron muchos docentes, las fuentes de información son fundamentalmente institucionales. A pesar de ser un proyecto que se construyó regionalmente y trató de involucrar a las comunidades de la región, las dificultades económicas provocaron que en pocos años se transfiriera al gobierno federal.

Motorcycle accidents are prevalent worldwide and pose a significant risk of morbidity and mortality. Motorcyclists are more likely to succumb to accidents compared to car users. The impact of motorcycle accidents is substantial on individuals, healthcare centers, and governments. This systematic literature review aims to summarize findings related to the mechanisms of motorcycle accidents, profiles of associated injuries, and mortality rates, with a focus on motorcyclists aged 15 to 65 years in the MENA region. PubMed and Web of Science were systematically searched from October 2013 to October 2022. Relevant reports were collected and reviewed for eligibility based on the inclusion and exclusion criteria. We identified 15 articles from the MENA region, covering countries such as Iran, Turkey, Saudi Arabia, Egypt, and the United Arab Emirates. The frequency of motorcycle accidents was highest during the summer season, and the most common mechanism involved collisions with other vehicles. Head and lower limb injuries were the most frequently reported anatomical injury sites. The mortality rate ranged from 0.49% to 4.5%.Motorcycle accidents can lead to severe injuries and fatalities. Governments and healthcare workers play a crucial role in raising awareness about preventable factors contributing to accidents and emphasizing the importance of wearing protective measures.

Many emergency departments are now evaluating the quality of airway management, with the first-pass success rate being a widely used indicator of competence that has been linked to adverse event rates. The present study aimed to quantify adverse events related to endotracheal intubation in emergency departments, focusing on the first-pass success rate.We conducted a thorough search of MEDLINE, EMBASE, and PubMed using keywords such as \"multiple intubation attempts,\" \"intubation,\" \"first-pass success,\" and \"learning curve\" to identify relevant research. Our search was further expanded to include references from the identified articles. We collected and assessed citations spanning a twenty-year period from 2000 to 2020, involving emergency airway management by both prehospital and in-hospital clinicians.Eight articles were included in the final review. Among them, three trials evaluated the impact of the number of intubation attempts on the complication rate, yielding odds ratios of 6.7 (n = 2284), 4.7 (n = 1903), and 4.5 (n = 2616). Multiple intubation attempts were found to increase the risk of complications, a finding supported by a 2004 analysis of 2833 airway management incidents. In this analysis, more than one intubation attempt was associated with a fivefold increase in the overall complication rate.First-pass success rates varied between 71% and 87.5% for prehospital physicians and between 60% and 97% for in-hospital physicians. Achieving first-pass success was shown to reduce problems and increase the likelihood of sufficient oxygenation. Conversely, multiple intubation attempts were correlated with a higher rate of unfavorable outcomes.

South African Industry and Geographic Dynamics Perspective on the Link Between Employee Diversity Attributes and Employee Productivity
Authors: Van Zyl Gerhardus
Published: December 2023

This study is part of an ongoing research project on various aspects of employee productivity in the South African workplace. The aim of the article is to measure the industry and geographic dynamics of the impact of different employee diversity attributes on productivity as no South African econometrically focused publications on this particular topic exist. I deemed it important to close this gap in the employee productivity literature. I applied an employee real remuneration model with a dissimilarity index vector and an industry dynamics vector to estimate the spillover effects of employee productivity for different employee diversity attributes. To validate the robustness of the estimates of the employee real remuneration model, estimations of the fixed-effect panel data were done for the full firm-based data sets. The estimation results indicated the same productivity pattern for the two industries in the three geographic areas. The productivity estimates suggest that the impacts of higher employee productivity spillovers (for all diversity subcategories) were more prominent for the area of the stronger gross geographic product. Limitations of this study that should be addressed are studies focused on the individual employee level and the productivity impact of the different levels of female remuneration gaps in the workplace. The estimation methodology applied in this study and the results thereof are intended to contribute to human resource policy debates on the impact of employee diversity attributes on employee productivity across industries and geographic areas in a diverse workplace.
Examining Chinese employees´ perceptual frameworks including their attitudinal orientations towards the concepts and implementation of shared leadership: An exploratory investigation
Authors: Wolf Marvin
Published: December 2023

In view of today´s dynamic business environment, shared leadership breaks with the classical leadership approaches by offering new possibilities of participation, active contribution and taking over responsibility for employees. Among other aspects, shared leadership certainly relies on highly motivated participants who are willing to implement this new leadership approach. This research study focuses on the motivational factors at work, attitude towards shared leadership and an implementation guideline for shared leadership in a Chinese culture context. This qualitative research is conducted by online-interviews of 10 Chinese citizens, supported by a semi-structured guideline. The results are inductively evaluated by Mayring´s procedure of qualitative content analysis. Regarding mentioned motivational factors, Chinese responses do not significantly differ from Western based literature. An ambivalent attitude towards shared leadership can be determined with transparent concerns that the Chinese participants have in mind. Nonetheless, chances and possible applications of shared leadership can be perceived which lead to a suggested step-by-step guideline, how to implement shared leadership in an existing organization. Among possible limitations, when evaluating the given responses, wishful thinking and reality should be considered. Furthermore, a restricted representativeness for Chinese society by convenience sampling should be noted. Follow-up studies could go further on quantitative researching with the collected impressions from this qualitative research. There could also be a longitudinal study to check for any changes of the attitude towards shared leadership.
Le personnage du Méchant dans Le Neveu de Rameau et dans le Dictionnaire philosophique : étude d’une ambivalence lexicographique au XVIIIe siècle
Authors: FROUREJ Abderrahmene
Published: December 2023

À partir de quel moment pouvons-nous dire qu’un personnage est méchant ? À la différence de certaines figures stéréotypées, certaines formes de malfaisance témoignent d’une plasticité étonnante. En mobilisant plusieurs définitions du XVIIe et du XVIIIe siècles, nous les confrontons à certaines manifestations de cette méchanceté au sein de la littérature, notamment dans Le Neveu de Rameau de Diderot et dans le Dictionnaire philosophique de Voltaire. Les personnages, étant des constructions d’idées, s’incarnent dans des dialogues ou à travers des anecdotes. Les idées qui en découlent visent à s’éloigner de l’image du bourreau machiavélique jusqu’à le voir apparaître comme une victime, invisible et médiocre.
Les voies vers l’Eldorado : une géocritique des migrations dans la littérature gambienne
Authors: COLY Sylvie
Published: December 2023

La migration revêt de nos jours un visage singulier qui porte généralement le nom d’immigration ou de migration clandestine et le continent européen en est très affecté. Cette ruée vers l’Europe connaît une envergure dramatique et l’art n’a pas manqué de s’emparer de la donne. En Gambie, le thème de ce voyage illégal connu sous le nom de ‘Back Way’ s’est frayé un chemin dans la littérature. Pour analyser ce thème d’actualité, nous avons choisi de traiter de la migration masculine en nous basant sur les romans de deux auteurs gambiens Kalilu Jammeh et Papa Jeng qui ont écrit respectivement Journey of Misery : From The Gambia to Spain et The Boat Boys : Barcelona or Barrsaxa. Les auteurs décrivent le même thème par le biais d’itinéraires ou de parcours qui posent la question de la représentation de l’ailleurs par rapport à l’espace d’origine, de l’altérité et de la survie entre rêves, illusions et réalités.

Published: December 2023

ABSTRACT: Herein, we report a stereoretentive and decar-boxylative C-3 functionalization of chromone-3-carboxylic acids with optically active aziridines via visible light irradia-tion. This metal-free and operationally simple protocol utilizes a simple combination of stable and inexpensive tetrabu-tylammonium iodide and visible light irradiation. It enables a facile and direct access to chiral 3-substituted chromenones with maintaining the optical purity of starting aziri-dines.Cross-coupling reactions allowing for efficient carbon–carbon as well as carbon–heteroatom bond formations are of crucial importance in the modern organic chemistry.1 Among them transition-metal-catalyzed decarboxylative cross-couplings utilizing carboxylic acids as substrates occupy a prominent position.2 They offer several distinctive advantages related to availability and price of carboxylic acid derivatives, their stability and handling as well as generation of less-toxic carbon dioxide as the by-product that reduces the waste treatment costs. While these methods have proven particularly useful for C(sp2)-C(sp2) bond formations and were applied for the synthesis of numerous relevant products ranging from pharmaceuticals to organic materials, their application in the C(sp2)-C(sp3) remains limited. Consequently, there is a need for the development of alternative, transition-metal-free cross-coupling reactions allowing for C(sp2)-C(sp3) bond formations.
Transferable Machine Learning Interatomic Potential for Bond Dissociation Energy Prediction of Drug-like Molecules
Authors: Gelžinytė Elena , Öeren Mario , Segall Matthew D. , Csányi Gábor
Published: December 2023

We present a transferable MACE interatomic potential that is applicable to open- and closed-shell drug-like molecules containing hydrogen, carbon, and oxygen atoms. Including an accurate description of radical species extends the scope of possible applications to bond dissociation energy prediction, for example, in the context of cytochrome P450 (CYP) metabolism. The transferability of the MACE potential was validated on the COMP6 dataset, containing only closed-shell molecules, where it reaches better accuracy than the readily available general ANI-2x potential. MACE achieves similar accuracy on two CYP metabolism-specific datasets, which include open- and closed-shell structures. This model enables us to calculate the aliphatic C-H bond dissociation energy (BDE), which allows us to compare reaction energies of hydrogen abstraction, which is the rate-limiting step of the aliphatic hydroxylation reaction catalysed by CYPs. On the “CYP 3A4” dataset, MACE achieves a BDE RMSE of 1.37 kcal/mol and better prediction of BDE ranks than alternatives - the semi-empirical AM1 and GFN2-xTB methods and the ALFABET model by St. John et al.1 that predicts bond dissociation enthalpies. Finally, we highlight the smoothness of the MACE potential over paths of sp3C-H bond elongation and show that a minimal extension is enough for the MACE model to start finding reasonable minimum energy paths of methoxy radical-mediated hydrogen abstraction. Altogether, this work lays the ground for further extensions of scope in terms of chemical elements, (CYP-mediated) reaction classes and modelling the full reaction paths, not only bond dissociation energies.

A thorough analysis of the situation observed in digitalizing monitoring technologies in Russia, helps set up the priority problems to be solved on the path of implementing the above national program, as well as draw up approaches to the solution of the same.
Combatants, Masculinity, and Just War Theory
Authors: Parsons Graham
Published: December 2023

Over that last several decades the ethics of war has grown into a major subfield in philosophy at the same time as large literatures have developed on the relation between gender and war as well as feminist approaches to the ethics of war. This article aims to contribute to these literatures and to bring them into closer contact. It argues that canonical just war theorists such as Grotius, Pufendorf, Vattel, and Walzer rely on appeals to masculinity to help ground the obligations of soldiers to participate in war upon command. This appeal helps them overcome their otherwise weak arguments for the political subordination of soldiers, or what I call the Internal Problem of the soldier. It also helps explain a problem that has vexed contemporary ethics of war scholars, namely, the supposed equal right to kill combatants in war, or what I call the External Problem of the soldier. If this is true, then just war theorists should be much more concerned with the gender and war literature and find common ground with feminists who have treated the problem of the political standing of soldiers as a philosophical priority.
Contextualizing, Clarifying, and Defending the Doctrine of Double Effect
Authors: Moschella Melissa
Published: December 2023

In recent years, a number of authors – such as Kershnar and Kelly, Steinhoff, and Scanlon – have criticized the doctrine of double effect (DDE) as incoherent, lacking an underlying rationale, or leading to counterintuitive conclusions.  These critiques, however, rest on a failure to understand the DDE’s broader theoretical context and presuppositions. This paper aims to clarify and advance the debate regarding the DDE by, first, outlining a contemporary version of the broader normative theory (i.e. the Aristotelian-Thomistic natural law tradition) within which the DDE finds its proper context, and explaining the rationale for the DDE within this context; second, clarifying the DDE’s proportionality condition to avoid common misinterpretations; and, third, showing how the DDE, when properly formulated and understood within the appropriate theoretical context, can withstand the recent criticisms that have been raised against it.

21. Yüzyılda Teknolojiye İnanç Merkezli Bir Karşı Duruş: Amiş Topluluğu
Authors: ÖNER Yasin
Published: December 2023

Çalışmanın konusu teknoloji çağı olan 21. yüzyılda inançları gereği bu yüzyıla ait modern kavramlardan kendisini soyutlamayı büyük oranda başarmış olan Amiş topluluğunun tarihsel gelişimi, inançları ve uygulamalarına dair bir değerlendirmedir. Çalışmanın amacı teknolojinin kullanımına dair karşı duruşun yanı sıra kılık kıyafetlerinden eğitim şekillerine, manuel tarım uygulamalarından izole edilmiş toplum yapılarına kadar pek çok farklı yönden günümüz modern toplum anlayışıyla taban tabana zıt bir imajinasyona sahip Amiş topluluğunu ana hatlarıyla ele almaktır. Bununla birlikte esas amaç göz önünde bulundurularak başta tevazu ve alçakgönüllülük olmak üzere modern dönemde bu ve benzeri kavramları tekrar canlandırabilme umudunu bünyesinde barındıran Amiş topluluğunun bu beklentiyi karşılayabilme olasılığı da sorgulanmıştır. Bahsi geçen hususlar aktarılırken özellikle Amişler’in tarihsel gelişimi konusunda kronolojik yöntemden faydalanılmıştır. Ayrıca Hıristiyanlığın Anabaptist koluna mensup olan Amişler’in diğer gruplarla olan benzerlikleri ve farklı yönleri değerlendirilmiştir. Çalışmada kaynak kullanımı hususunda ise Amiş topluluklarını etraflıca ele alan ve bu konuda yeterli veriye sahip olduğu düşünülen eserlere başvurulmuştur. Böylece inançlarını, uygulamalarını ve toplumsal yapılarını korumak adına modern dünyayla aralarına set çeken Amişler’in hedeflerine ulaşma noktasındaki çabaları ele alınmış ve bu yöndeki başarı/başarısızlık durumları değerlendirmeye çalışılmıştır.

The aticle presents several different ways of popularizing scientific knowledge. It is not scientific in the sense that it is not a report on a systematic study of the literature or empirical research. It is a tool room: a repository we can turn to in search of tools to help us solve a problem. The article offers three tools. The first is a typology of forms of participation in science. I treat the typology as a tool, too, because defining a problem can be seen as part of the problem-solving process. It's important to understand that there are different forms of science popularization and citizen science participation: each form requires different competencies and will work in a different situation. It's also important to understand that there is a difference between science communication (i.e., what scientists do as part of their work) and science communication (i.e., dissemination of scientific results outside of science). These are two different modes of communication and require separate skills. The second tool is a set of heuristics that may be of interest to those already parsing science communication, but having difficulty communicating science. The last tool is a proposal for a science popularizer's checklist. It is based on my own experience. Anyone interested in science communication can check this tool in action, modify it for themselves, or create their own list, which I encourage you to do.
