Authors: Furdui Monica , Marcu Laura , Sula Ledia
Published: May 2022

The article discusses the subject of pupils’ attachment to the specialization and the educational institution to which they are enrolled, through the perspective of a double approach: pedagogical and marketing. In both cases, the content of the concept, its role and the means by which it can be supported are presented. At the same time, the theoretical approach is completed by a case study on educational institutions in a locality in Romania, following the way in which the marketing strategy is used to increase the degree of attachment of pupils to these institutions.
Considerations regarding the Accounting of Value Added Tax – National Particularities within the European Context
Authors: Necula Anda Ileana , Manole Andrei Marcel , Şenchea Florea Anca Daniela , Stancu Liţă Izabela
Published: May 2022

The value added tax (VAT) is an indirect tax on consumption, of a general nature, applied to value of economic goods, regardless their final destination, i.e., consumer goods or production means, as well as to the execution of works and providing of services. According to its name, the calculation basis of VAT, paid by the consumer and due by the seller, is the added value related to the last link in the supply chain; this feature ensures the transparency of the tax. VAT is a consumption tax applied to almost all goods and services purchased and sold for use or consumption in the European Union (EU). At Community level, there are standard VAT rules, but their application may differ among countries. In most cases, VAT must be paid for all goods and services at all stages of the supply chain, including sale to the final consumer. Until 1989, Romania applied a single sales tax, followed by the tax on the movement of goods between 1989 and 1992. The latter was replaced by VAT, starting with July 1, 1992, as part of the initial efforts of transition towards the convergence with the applicable tax system within the European context. The introduction of value added tax has determined, in the early stage following the implementation of this measure, the increase of the consumer price index, but later it had a stimulating effect on investments and exports.

Naturaleza y paisaje: Nociones para la construcción de las percepciones y las emociones del bosque tropical amazónico en el nuevo mundo
Authors: Useche López Camilo Andrés
Published: May 2022

Desde la llegada de los europeos a América, surge una nueva manera de percibir los bosques. El traspaso de imaginarios provenientes de la Antigüedad y de la Edad Media a los nuevos territorios anegó los bosques tropicales de un nuevo significado, confinándolos espacialmente a las márgenes del Nuevo Mundo. Con el pasar de los años, esos bosques, que demarcaban los límites de la “civilización”, se fueron convirtiendo en una fuente innegable de recursos y sensibilidades hasta hoy en día. Lo anterior conlleva la necesidad de generar nuevas aproximaciones al estudio de las percepciones y las emociones alrededor de la idea de naturaleza y paisaje sobre los bosques tropicales. Este artículo de reflexión pretende dar algunas nociones o aproximaciones para el estudio de la naturaleza y el paisaje en el bosque tropical amazónico a partir del siglo XVI. Los conceptos de naturaleza y paisaje permiten sumergirnos en el universo de la historia sensible del espacio tropical y funcionan como herramienta para la comprensión de los imaginarios y representaciones que emergen como dispositivos de poder en la selva amazónica.
Patenting the innovation and regulatory considerations
Authors: Sharma Bindu
Published: May 2022

Bringing a medical product in the market is far more complicated compared to any other product due to its sensitivity and direct implication to human life. On one hand, legal protection in the form of patent may be needed and on the other hand the approval to manufacture and sell product should be obtained. In this article, we will discuss the role of Intellectual Property Rights in protecting innovations as well as regulatory requirements, specifically in case of medical products.
To estimate the prevalence of thrombocytopaenia and its role as prognostic marker in patients of paediatric intensive care unit
Authors: Joshi Gurudutt , Budh Hetal
Published: May 2022

Objectives:

Platelets play an important role in normal homeostasis and thrombus formation. They help in reducing vascular permeability, mediating inflammatory processes, promoting wound healing and host defence mechanisms. The aim of this was to estimate the prevalence of thrombocytopaenia, to categorise thrombocytopaenia according to the severity and to evaluate the role of thrombocytopaenia as a prognostic marker in patients admitted in PICU.

Materials and Methods:

This was a prospective observational study over a period of 15 months. One hundred and eighty patients of age 1 month–17 years, critically ill, admitted in PICU or transferred from paediatric ward were enrolled. Those, who had thrombocytopaenia during admission or during PICU stay, were labelled as ‘Thrombocytopaenia’ group, while the remaining patients who did not have thrombocytopaenia were grouped as ‘No thrombocytopaenia’ group.

Results:

The prevalence of thrombocytopaenia in PICU was 37.78% category wise, 35.29%, 33.82%, 19.12% and 11.76% of patients had mild, moderate, severe and very severe thrombocytopaenia, respectively. Mean duration of stay in PICU was more with severe and very severe thrombocytopaenia, followed by moderate and mild thrombocytopaenia, which was statistically significant (P = 0.00037). Mortality was higher in thrombocytopaenic group as compared to non-thrombocytopaenic patients expired, which was statistically significant (P = 0.001013).

Conclusion:

The prevalence of thrombocytopaenia in this study was similar to other studies. Severity of thrombocytopaenia correlated well with the duration of PICU stay. Overall mortality was 22.22% in this study.
The Concept of Multiple-Nutrient-Limited Growth of Microorganisms and Some of Its Possible Applications in Biotechnology Processes
Authors: Egli Thomas
Published: May 2022

Justus von Liebig's 'Law of the minimum' states that usually one nutrient restricts the maximum quantity of biomass that can be produced within a system where all other nutrients are available in excess. This general rule has been applied also to the growth of microorganisms, e.g., by adjusting the relative concentrations of the individual nutrients in growth media such that one of them, in the case of heterotrophic microbes usually the carbon source, determines the maximum cell density that can be obtained in a culture. However, recent experimental data from chemostats have demonstrated that growth of microbial cultures can be limited simultaneously by two or more nutrients. The experimental evidence supporting the limitation of growth by multiple nutrients is reviewed here, and a concept is presented that allows predicting the zones where multiple-nutrient-limited growth occurs. The information so far available indicates that multiple-nutrient-limited growth conditions allow to force cells into a physiological status that cannot be achieved under traditional single-nutrient-limited growth conditions. Two examples are given which demonstrate that cultivation of microbial cells under multiple-nutrient-limited growth conditions can be used to enhance the productivity of biotechnological processes.
Regulations in Biotechnology: Administrative Handling and Scientific Content
Authors: Käppeli Othmar
Published: May 2022

The administrative handling of regulatory oversight procedures differs from country to country, whereas the scientific data required for the safety assurance are similiar in most instances. Safety issues for contained biotechnology applications are mainly a matter between industry and
the government agencies involved. Deliberate release of transgenic organisms and the market introduction of transgenic food, however, produce much public debate. It is assumed that shortcomings related to risk-assessment methodology as, e.g., the lack of accepted protection goals and
the continuing discussions about the validity of comparative risk assessment may be reasons for the current situation.

Published: May 2022

Hemolytic disease of the newborn is an often fatal condition of some newborn babies due to the immunogenicity of their Rh D positive erythrocytes in the Rh D negative mother. This condition can be prevented by injecting anti-Rh D antibodies. The current source of these antibodies is blood from immunized human donors. In order to avoid problems with limited supply and donor safety, the Rh D project was set up to develop recombinant monoclonal anti-Rh D antibodies as a possible replacement. In a multidisciplinary collaboration between the Zentrallaboratorium Blutspendedienst (ZlB) of the Swiss Red Cross, the Center of Biotechnology of the University and the EPFL (CBUE), and the Institute of Chemical and Biochemical Engineering (EPFl), co-funded by the Swiss National Science Foundation and ZLB, a candidate monoclonal anti-Rh D antibody has been selected, expressed in CHO cells, and a manufacturing process for large-scale production has been developed.

Authors: Pfaar Ulrike , Gygax Daniel , Gertsch Werner , Winkler Tammo , Ghisalba Oreste
Published: May 2022

The production of two O-glucuronides in an enzyme membrane reactor on a 100 to 200 mg scale was examined. The aglycons were conjugated with the co-substrate β-D-uridine diphosphoglucuronic acid (UDPGA) in the presence of a guinea-pig liver preparation. The continuous synthesis, which was run in an enzyme membrane reactor, was followed depending on the substrate up to 118 hours or 24 hours, respectively. The reaction was monitored by TLC or HPLC. The purification of the two glucuronides was carried out by ion-exchange chromatography and by reversed-phase HPLC.
Microbial Hydroxylation and Simultaneous Formation of the 4''-O-Methylglucoside of the Tyrosine-Kinase Inhibitor CGP 62706
Authors: Kittelmann Matthias , Oberer Lukas , Blum Wolfgang , Ghisalba Oreste
Published: May 2022

Two fungal strains of Beauveria bassiana, DSM 875 and DSM 1344, hydroxylated CGP 62706, an inhibitor of the EGF-receptor tyrosine kinase, in the C(4') position and subsequently formed the glucosylated metabolite with 5–11% and 7–15% yield, respectively. The reaction could be successfully scaled up to 3 l fermentation volume with strain DSM 875. The structure of the glycosylated compound was determined by micro-HPLC-MS and NMR after production by fermentation on the mg scale. In addition, the biotransformation also provides access to the free 4'-hydroxylated compound, as the glycoside can easily be hydrolyzed.
Sequencing of β-Peptides by Mass Spectrometry
Authors: Schreiber Jürg V. , Quadroni Manfredo , Seebach Dieter
Published: May 2022

Seven ?-peptides containing up to 18 β2-, β3- and β2,3-amino acids have been subjected to ESI-tandem mass spectrometry (low-energy fragmentation, positive ions). From the fragment ions formed from the free β-peptides, as well as from the corresponding methyl esters (+14 U) and N-acetyl derivatives (+42 U), the known sequences of β-amino acids could be confirmed unambiguously with the program Sherpa. Thus, the commonly used MS-sequencing procedure for α-peptides can be adopted for β-peptides without modification. However, there are pronounced differences in the fragmentation patterns of the two types of peptides: the β-peptides disclose their relationship to Mannich bases in the mass-spectrometric experiment by the elimination of ammonia from the N-terminus (→ RCH=CH-CO-NH-R') and the occurence of retro-Mannich cleavage (cf. formation of HN=CHR + CH3CO-NH-R' from β-amino-acid residues).
Enforcement of Intellectual Property Laws
Authors: Lutz Martin
Published: May 2022

The present article concentrates on Patent Law with some comparison with the less contested problems of Trademark and Copyright enforcement.By the Grant of Patents, the State conveys to the Patent Owner an absolute right over commercially applicable technical achievements for a limited period of time. The Patent Owner has an exclusive right to exercise the invention, to permit third parties to work the invention against compensation and to prevent its unauthorised use. Effective patent protection requires not only a reliable system of grant and administration but equally important an effective system of enforcement. The TRIPs agreement which forms part of the GATT Agreements concluded in Marrakech in 1994 has established uniform minimum standards of enforcement practically worldwide. The implementation of the TRIPs Agreement is far from completed.In Switzerland 26 Cantonal Courts are competent for patent enforcement. With the exception of the five Courts of Commerce (Zürich, Bern, Aargau, St Gallen and Geneva) the competent Courts have no technical knowledge and little experience in patent matters. The Courts are forced to rely almost exclusively on outside experts even in injunction proceedings. As a result, patent enforcement in Switzerland is often very slow and there is little reliability and continuity of jurisprudence. As the Supreme Court may only re-examine questions of law and considers itself as bound by the facts established by the Cantonal Courts including Court Expert opinions it is unable to impose the desirable harmonisation of patent law jurisprudence. Patents that cannot be properly and timely enforced are of limited value. Insufficiencies of the enforcement procedures in Patent Law in Switzerland are detrimental to the encouragement of research and development and thus to the Swiss economy. It would be desirable to concentrate the enforcement of Patent Law in Switzerland to a Federal Patent Court with panels of technically trained judges composed by a Court of First Instance (possibly with two Chambers for the German and French part of the Country) and a Federal Court of Appeals following the US example.
High-Resolution Spectroscopy of High Rydberg States: Chemical and Technological Applications
Authors: Merkt Frédéric
Published: May 2022

High Rydberg states of atoms and molecules possess unusual properties that can be exploited in chemistry and technology. The extreme sensitivity of these states to external influences makes them ideal probes of their environment and they can be used to measure electric fields and ion concentrations in the gas phase with high accuracy. The highest Rydberg states with principal quantum number n ≥ 200 lie energetically so close to successive ionization thresholds in atoms and molecules that they can be used to determine ionization potentials precisely and to extract detailed information on the energy level structure of molecular cations. To investigate and better exploit the properties of high Rydberg states, we have developed new high-resolution vacuum ultraviolet laser sources and combined these with millimetre waves in double-resonance experiments. In these experiments a spectral resolution of up to 60 kHz can be achieved. High-resolution spectroscopy is ideally suited to study the fascinating behaviour of high Rydberg states and opens the way to promising applications in the gas-phase chemistry of unstable and charged particles and in measurement technology.
Exploring the Combinatorial Explosion of Amine–Acid Reaction Space via Graph Editing
Authors: Zhang Rui , Mahjour Babak , Cernak Tim
Published: May 2022

Amines and carboxylic acids are abundant chemical feedstocks that are nearly exclusively united via the amide coupling. The disproportionate use of the amide coupling leaves a large section of unexplored reaction space between two of the most common chemical building blocks. Herein we conduct a thorough exploration of amine–acid reaction space via systematic enumeration of reactions involving a simple amine–carboxylic acid pair. This approach to chemical space exploration investigates the coarse and fine modulation of physicochemical properties and molecular shapes. While the invention of reaction methods becomes increasingly automated bringing conceptual reactions into reality, our map will provide an entirely new axis of chemical space exploration for rational property design.
Crystallize it before it diffuses: Kinetic stabilization of thin-film phosphorus-rich semiconductor CuP2
Authors: Crovetto Andrea , Kojda Danny , Yi Feng , Heinselman Karen N. , LaVan David A. , Habicht Klaus , Unold Thomas , Zakutayev Andriy
Published: May 2022

Numerous phosphorus-rich metal phosphides containing both P-P bonds and metal-P bonds are known from the solid-state chemistry literature. A method to grow these materials in thin-film form would be desirable, since thin films are required in many applications and they are an ideal platform for high-throughput studies. In addition, the high density and smooth surfaces achievable in thin films are a significant advantage for characterization of transport and optical properties. Despite these benefits, there is hardly any published work on even the simplest binary phosphorus-rich phosphides. Here, we demonstrate growth of single-phase CuP2 films by a two-step process involving reactive sputtering of amorphous CuP{2+x} and rapid annealing in an inert atmosphere. At the temperature required for crystallization, CuP2 tends to decompose into Cu3P and gaseous phosphorus. However, CuP2 can still be synthesized if the amorphous precursors are mixed on the atomic scale and are sufficiently close to the desired composition (neither too P poor nor too P rich). Fast formation of polycrystalline CuP2, combined with a short annealing time, makes it possible to bypass the diffusion processes responsible for decomposition. We find that thin-film CuP2 is a 1.5 eV band gap semiconductor with interesting properties, such as a high optical absorption coefficient (above 1e5 cm-1), low thermal conductivity (1.1 W/Km), and composition-insensitive electrical conductivity (around 1 S/cm). We anticipate that our processing route can be extended to other phosphorus-rich phosphides that are still awaiting thin-film synthesis, and will lead to more complete understanding of these materials and of their potential applications.
SMART-metabolite-ID: Semi-automatic and reliable identification of metabolites from complex mixtures by correlation of 1H NMR, MS and LC data
Authors: Watermann Stephanie , Bode Marie-Christin , Hackl Thomas
Published: May 2022

Due to the large number of metabolites of various compound classes present in natural products, which in addition occur in high concentration differences, the identification of individual metabolites from either 1H NMR spectra or MS spectra is hardly possible due to signal overlap and the lack of information from interrelated signals of the same compound. This paper presents a method for the three-dimensional correlation of NMR and MS data over the third dimension of the time course of a chromatographic fractionation. Compounds do not need to be isolated individually, but the NMR and MS signals of the individual compounds can be correlated mathematically. The app SMART-metabolite-ID (Semi-automatic Mixture Analysis for Reliable and direcT metabolite IDentification) was implemented in MATLAB and provides semi-automatic detection of correlated NMR and MS data. Thereby, the app enables fast and reliable dereplication of known metabolites and facilitates the dynamic analysis for the identification of unknown compounds in any complex mixture. The strategy was validated using an artificial mixture and tested further on a polar extract of a pine nut sample. Straightforward identification of 40 metabolites could be shown, including the identification of β-D- glucopyranosyl-1-N-indole-3-acetyl-N-L-aspartic acid (1) and Nα-(2-hydroxy-2-carboxymethylsuccinyl)-L-arginine (2), the latter being identified in a food sample for the first time.
Bring Chemical Intuition to Chips: Transferable Chemical-intuitive Model to Predict Photophysics of Organic Aggregates
Authors: Gong Junyi , Tang Ben Zhong
Published: May 2022

While machine-learning methods indicated good adaptability for machine-learning algorithms in the pan-chemistry field by its breakthroughs in pharmacy. Materials research still benefits from such new techniques fewer due to the inconsistency in the paradigm of study in the diversely different subareas which demand special treatment individually. In this contribution, we proposed an innovative design of the embedding method, which is inspired by chemical intuition, to bring neural networks into the field for modelling photophysics of the organic light-emitting materials in condensed states. We outline this framework and demonstrate its successful implementation in the predictive classification of fluorophores by its mechanisms, direction of spectra shift from solution to solid-state, and regression of spectral features, including emission peaks wavelengths in pristine solid-state and nano-aggregates. Our work may serve as an example for a specific area of materials research to transfer the empirical chemical intuition into machine-learning models and build comprehensive performance-oriented pre-screening systems to develop new compounds with demanded characters.
Charge Transfer in Metallocene Intercalated Transition Metal Dichalcogenides
Authors: Kuo Ding-Yuan , Rice Peter , Raugei Simone , Cossairt Brandi
Published: May 2022

Intercalating redox active molecules into layered materials expands their functionality for emerging energy technologies. However, the mechanism of charge transfer to and from these small molecules within the confined environment of the layered host material and their role in charge storage are largely unexplored. Herein we examine charge transfer processes in metallocene intercalated transition metal dichalcogenides, including MoS2 and WS2. Combining experimental and computational analyses, we explore the orientation of the metallocene as a function of substitution pattern and study the influence of the metallocene redox potential on the electronic structure of MoS2 and WS2. We further examine the electrochemical response of these intercalated compounds via cyclic voltammetry. Our results show that the intercalated metallocene remains redox active and its redox potential is dramatically affected by the speciation and concentration of cations in the electrolyte. Our work provides a general strategy for studying the electronic and electrochemical responses of redox active intercalants in layered materials and highlights emergent phenomena regulating charge transfer that may be useful in energy storage and catalysis.
Explaining structure-activity relationships using locally faithful surrogate models
Authors: Gandhi Heta A. , White Andrew D.
Published: May 2022

We present a model-agnostic method that gives structure-activity explanations of black-box models. Machine learning models are now common for molecular property prediction and chemical design. They typically are black boxes -- having no explanation for predictions. Our method uses surrogate models to attribute predictions to chemical descriptors and molecular substructures, independent of the black box model inputs. Our approach provides explanations consistent with chemical reasoning, like connecting existence of a functional group or molecular polarity.
The Informational Effect of Monetary Policy and the Case for Policy Commitment
Authors: Jia Chengcheng
Published: May 2022

I study how the informational effect of monetary policy changes the optimal conduct of monetary policy. In my model, the private sector extracts information about unobserved shocks from the central bank’s interest rate decisions. The central bank optimally changes the informational effect of the interest rate by committing to a state-contingent policy rule, in which case the Phillips curve becomes endogenous to the central bank’s optimization problem. In a dynamic model, the optimal policy rule overshoots the natural-rate shock and gradually responds to the cost-push shock, which makes the interest rate change expected output growth but not expected inflation.
Constructing Density Forecasts from Quantile Regressions: Multimodality in Macro-Financial Dynamics
Authors: Mitchell James , Poon Aubrey , Zhu Dan
Published: May 2022

Quantile regression methods are increasingly used to forecast tail risks and uncertainties in macroeconomic outcomes. This paper reconsiders how to construct predictive densities from quantile regressions. We compare a popular two-step approach that fits a specific parametric density to the quantile forecasts with a nonparametric alternative that lets the “data speak.” Simulation evidence and an application revisiting GDP growth uncertainties in the US demonstrate the flexibility of the nonparametric approach when constructing density forecasts from both frequentist and Bayesian quantile regressions. They identify its ability to unmask deviations from symmetrical and unimodal densities. The dominant macroeconomic narrative becomes one of the evolution, over the business cycle, of multimodalities rather than asymmetries in the predictive distribution of GDP growth when conditioned on financial conditions.

Furthermore we study the approximate preserving mapping and give some properties.
Rüzgâr Yapısı Gösteren Kuazarların Fotometrik İncelenmesi – I: Parlaklık Değişim Genliği ve Fiziksel Parametreler Arasındaki İlişkiler
Authors: Filiz Ak Nurten , Sayılı Ömür
Published: May 2022

Rüzgâr yapısına sahip olduğu tayfsal gözlemler ile belirlenmiş Geniş Soğurma Çizgili 1886 kuazarın zamana bağlı parlaklık değişimleri, Catalina Sky Survey veri tabanından alınan ışık eğrileri kullanılarak incelenmiştir. Kuazarla-rın fotometrik parlaklık değişim genliğini ölçmeye uygun bir parametre tanımlanmıştır. Parlaklık değişim genliği parametresinin rüzgâr yapısına sahip kuazarlar için dağılımı incelendiğinde, asimetrik bir yapıya sahip olduğu ve normal dağılıma uymadığı görülmüştür. Dağılımın simetrisini bozan etkinin ağırlıklı olarak büyük genlikli değişim-ler gösteren kuazarlardan kaynaklandığı belirlenmiştir. Rüzgâr yapısına sahip kuazarların parlaklık değişimi ile kuazara ait fiziksel parametreler arasında bir bağıntı olup olmadığını araştırmak için 1886 rüzgarlı kuazar içerisin-den büyük değişim genliği gösteren ve küçük değişim genliği gösteren iki alt grup belirlenmiş, iki farklı grup içerisinde yer alan kuazarlara ait kırmızıya kayma, görünür ve mutlak parlaklıklar, ışınım gücü ve merkezi kara delik kütlesi dağılımları kıyaslanmıştır. Yapılan analizler, görünür ve mutlak parlaklıklar ve ışınım gücü bakımından ortak bir sonuca işaret etmektedir; büyük değişim genliğine sahip kuazarlar daha sönük olma eğilimindedir. Bu bulgu, ana örneklemin tamamı için uygulanan korelasyon testleri ile de doğrulanmıştır. Bu çalışma, daha önce normal kuazar-lar için ortaya koyulan parlaklık ve değişim genliği arasındaki bilinen ilişkinin, rüzgâr yapısına sahip kuazarlar için de geçerli olduğunu ilk kez ortaya koymaktadır. Bu sonuçlara göre, rüzgâr yapısına sahip kuazarların parlaklık değişim mekanizmaları bakımından normal kuazarlarla aynı olduğu düşünülmektedir. Ayrıca, güçlü ışınıma sahip kuazarların az değişim göstermesi, parlaklık değişimlerinin disk kararsızlığından kaynaklandığı yönündeki yaygın görüşü desteklemektedir.

Bu çalışmada, mevcut meteorolojik koşullar ve hava kirleticilerinin seviyeleri istatiksel olarak incelenmiştir. Çalış-mada, hava kirleticileri ve meteorolojik parametreler (sıcaklık, rüzgar hızı, nem, basınç ve karışım yüksekliği (sabah – öğlen)) arasındaki ilişkinin belirlenmesi amacıyla yapılan analizlerde özellikle sonbaharın sonlarında ve kış aylarında pik yaptığı tespit edilmiştir. Balıkesir şehir merkezinde, PM10 ve SO2 seviyelerindeki değişimler ile ilgili en yüksek korelasyon katsayısına sahip olan meteorolojik parametreler sırasıyla, rüzgar hızı (r=-0,45) ve sıcaklık (r=-0,53) olarak tespit edilmiştir. PM10 değişimini açıklayabilmek için yapılan regresyon analizinde, nem(rh) ve karışım yüksekliği (sabah) verilerinin modelde etkilerinin olmadığı görülmüştür (pnem=0,60 > 0,05 ve pKar. Yük. Sab.=0,34 > 0,05). Yine, SO2 tahmini için oluşturulan regresyon modelinde ise sadece karışım yüksekliği (öğlen) verile-rinin modelde etkisinin olmadığı görülmüştür (pKar. Yük. Öğ.=0,65 > 0,05).PM10 için ölçüm değeri 100 µg/m3’ten büyük olan, 2017-2019 yılları arasında toplam 4 faklı dönemden oluşan epizot dönem tespit edilmiştir. Korelasyon analizi sonuçlarına göre birinci dönemdeki PM10 değerleri ile karışım yüksekliği (öğlen) değerleri ile aralarında pozitif yönde r=0,58 değerinde korelasyon tespit edilmiştir. Diğer dönem-lerde ise PM10 seviyelerindeki değişimlerin karışım yüksekliği (sabah-öğlen) değerleri ile istatistiksel olarak önemli düzeyde ilişki saptanmamıştır.

Meteorology stations sold in the market have various difficulties in terms of their use, also these systems are costly to obtain. With state of the art sensor technologies, the development of mini weather stations has become easier. This study focuses on the development of a model weather station device using temperature, relative humidity, UV, LDR Light, rain and soil moisture sensors to collect major environmental data. The measured data were wirelessly transmitted to the remote station for logging via the GSM module and the information was sent to the database in the internet environment. In addition, the data from the sensors are organized by correlation. The classification was made according to the data obtained from the rain sensor and the relationship between the other 5 sensors used in the device to the rain classification was examined. Sensor data were scaled between 0-1 with min-max normalization before being subjected to deep learning and machine learning training. In the Decision Tree (DT) a model score of 0.96 was obtained by choosing the maximum depth of 20. The artificial neural network (ANN) yielded a classification score of 0.92 using 4 hidden layers and 100 epochs in the artificial neural network model.
Gender Gap or Gender Differences? Gender and Political Participation in Canada
Authors: Houle Nicole
Published: May 2022

Unequal participation in certain types of political engagement creates unequal influence on political and civil matters (Boulianne, 2022). Studies find that men and women tend to do a similar amount of political participation, with women engaging in more private and flexible forms, and men participating in more direct and collective forms (Bode, 2017; Coffé & Bolzendahl, 2010; Van Duyn et al., 2019; Pfanzelt & Spies, 2019). However, more data is needed when considering Canadian trends, especially when it comes to the causes of these trends. In this study, I conduct statistical analysis of secondary data from a February 2021 Canadian survey (n=1,568) designed by Dr. Shelley Boulianne. I determine which forms of political participation have gendered participation gaps and whether or not these are related to conflict avoidance tendencies and having political female role models. I find few gender differences in political participation.  Some small gender differences persist in online forms of political participation, such as signing petitions online and commenting on news sites. Men were more likely post comments on news sites, compared to women; women more likely to sign online petitions, compared to men. As such, political participation moves online, the gender gap may be reproducing itself in online spaces.

ve öğretmenlerin örgütsel bağlılığına etkilerini incelemektir. Bu amaç doğrultusunda araştırmacılar, çalışma grubuna yöneticilerin sınırlı görev süresi ile okul kültürü, okul başarısı ve öğretmenlerin örgütsel bağlılıkları arasındaki
ilişki hakkındaki fikirlerini sormuşlardır. Çalışma grubu, 4 kadın ve 4 erkek olan 8 kişiden oluşmaktadır. Katılımcılar, en az 10 yıl meslekî kıdemi olan ve en az 2 farklı kurumda çalışmış 4 öğretmen ve 4 yöneticidir. Çalışma nitel
araştırma yöntemiyle yapılmıştır. Araştırma deseni olarak fenomonoloji tercih edilmiştir. Veri toplama aracı olarak yarı yapılandırılmış mülakat yöntemi kullanılmıştır. Elde edilen bulgular, betimleyici bakış açısı ile analiz edilmiştir.
Katılımcılar, yöneticilerin 4 yıl süreyle görev yapmasının kurum kültürüne, okul başarısına ve öğretmenlerin örgütsel bağlılığına etkilerinin yöneticinin liderlik tarzı ve özellikleriyle ilgili olduğunu belirtmişlerdir. Bazı katılımcılar
için 4 yıl etkili yönetim için yeterli süre olarak görülmüştür. Bazı katılımcılar ise sürenin sınırlı olmasından ziyade yöneticinin öğretmenlerle, velilerle kurduğu iletişimin ve tecrübesinin kurum kültürü, akademik başarı ve örgütsel
bağlılık üzerinde etkili olduğunu düşünmektedir.

Bu çalışmanın amacı, yabancı sermayeli hayat dışı sigorta şirketlerinin aktif kârlılığını belirleyen faktörleri analiz etmektir. Çalışmada ayrıca şirket düzeyindeki değişkenlerin karlılık performansı üzerindeki etkisinin şirket büyüklüğüne
bağlı olup olmadığını araştırılmıştır. Çalışmada, Türkiye'de faaliyet gösteren 18 sigorta şirketinin 2010 yılının ilk çeyreği ile 2020 yılının ikinci çeyreği arasındaki üçer aylık veri setine panel regresyon analizi uygulanmıştır.
Analiz sonuçlarına göre, küçük ölçekli sigorta şirketlerinin aktif kârlılığının sırasıyla firma büyüklüğü, faaliyet giderleri, finansal kaldıraç, hasar-prim oranı ve yatırım getirilerinden önemli ölçüde etkilendiği tespit edilmiştir.
Ayrıca, büyük ölçekli sigorta şirketlerinin aktif karlılıklarının ise firma büyüklüğü, likidite oranı, sermaye yeterlilik oranı ve hasar-prim oranı gibi değişkenlerden anlamlı bir şekilde etkilendiği tespit edilmiştir. Dolayısıyla,
bu sonuçlar göstermektedir ki sigortacılık sektöründe karlılık üzerinde etkili olan faktörleri araştırırken şirket büyüklüğünün dikkate alınması gerektiği gerçeğini ortaya koymaktadır. Çalışmadan elde edilen bulgular hem sektördeki

%35.6’sı Z kuşağında, %31.7’si 1. sınıfta ve %71.2’si kadındır. Öğrencilerin HMYTÖ toplam puanı 153.47±16.03, hemşirelik mesleğinin özellikleri alt boyut puanı 79.27±9.63, Hemşirelik mesleğini tercih etme durumu alt boyut puanı
36.11±5.35 ve Hemşirelik mesleğinin genel durumuna yönelik tutum alt boyut puanı 38.04±5.34 olarak bulunmuştur. Yapılan analizler sonucunda hemşirelik mesleğini tercih etme durumu alt boyutu dışında tüm boyutlarda Y kuşağındaki
öğrencilerin puan ortalamalarının Z kuşağındaki öğrencilerden daha yüksek olduğu ve bu farkın istatistiksel olarak anlamlı olduğu saptanmıştır (p<0.05). Ayrıca sınıf düzeyi, cinsiyet, mezun olunan lise, ailenin gelir düzeyi,
baba eğitim durumu, kendi isteğiyle hemşirelik bölümüne gelme, kendi isteğiyle hemşirelik mesleğini seçme ve mesleği sevme durumu gibi özelliklerin HMYTÖ alt boyut ve toplam puan ortalamalarında istatistiksel olarak anlamlı farklılığa
sebep olduğu saptanmıştır (p<0.05). Sonuç olarak Y kuşağındaki öğrencilerin Z kuşağındaki öğrencilere göre daha olumlu tutuma sahip oldukları saptanmıştır. Okullarda öğrencilerin dahil oldukları kuşakların özellikleri göz önünde
bulundurularak mesleği sevmelerine ve olumlu tutum geliştirmelerine katkı sağlayacak nitelikte faaliyetlerin planlanması önerilmektedir.

Authors: SARI Özgür
Published: May 2022

Mainly in the Exile in 1864, most of the Circassians, who came to Turkey geography in 19th century, are today forming one of the many ethnic groups considered to be the wealth of the society in Turkey. With the intergenerational change,
Circassians, who have been integrated into society, have also changed their point of view towards their ethnic identity. As generations change, the processes of constructing ethnic identity have transformed and they construct their
ethnic identities with different parameters. This study, which analyzes these parameters in the light of the most basic theories of nationalism, pirmordialism, circumstantialism and constructivism, was carried out in the provinces
of Kayseri, Konya, Ankara, Düzce and Sakarya. In 2 villages selected from these five provinces; total of 10 villages, were asked to 100 Circassians who were selected with the snowball method. The age ranges of the people in our
sample, of which 54 are men and 46 are women, vary between 18 and 64. The information obtained as a result of the study conducted with 20 open-ended qualitative questions was analyzed in the light of nationalism theories. As a
result, it is understood that while the older generation constructs their ethnic identities on the theory of primordialism, the young people mostly define their ethnic identities according to the constructivism and circumstantialism
theories. Another variable was gender. It has been revealed that women are more primordialist in terms of practicing traditions and keeping the language alive than men. On the other hand, men's ability to use the language, their
desire to develop the language and transfer it to their children is less. Men are more flexible than women when it comes to applying traditions. In this case, it is understood that women are positioned closer to primordialism theory
than men, while men are more positioned according to circumstantialism theory
