How do people make their decisions? Searching for the answer in the relevant literature, we can find that decisions are based either on rationality or intuition. Rational thinking is mainly observed in situations characterized by certainty (in terms of data or the consequences of decisions), while heuristic intuitive methods are mainly observed in situations of uncertainty. Training for the enhancement of decision making skills usually employs problem-based activities which mainly focus either only on rationality or only on intuition. However, problems in real life cannot always be solved with the contribution of only one way of thinking. In a decision making process often rationality works up to an extent and then intuition will lead to the final decision. For this reason, we designed and developed a game-based learning activity that enhances both rational and intuitive decision making skills. More specifically, we created a decision scenario in a virtual environment in which participants were provided with uncertainty-based information in their decision making process. As they tried to follow a rational decision making process, most of them realized that based on the given information they were confused and they had to decide intuitively at the end. This experiential learning activity was a tickler for the participants to decide under uncertainty and trust their intuition.

"This article delves into the operationalization of collaborative problem-solving (CPS) skills, focusing on the essential aspects required to effectively apply CPS in the modern digital age. The article emphasizes the growing significance of CPS skills as technology-based work and the automation of routine tasks demand proficiency in addressing non-routine, complex challenges. To enable successful CPS, a new set of skills including information literacy, divergent thinking, and problem-solving, both individually and collaboratively, are explored. The article investigates the strategies and approaches employed by individuals and teams when engaging in collaborative problem solving, with an emphasis on knowledge sharing and skill pooling. The study highlights the criticality of CPS as an invaluable skill set, enabling individuals to effectively collaborate and overcome intricate problems. Moreover, as contemporary work environments increasingly rely on successful group problem solving, the significance of operationalizing CPS is expected to continue growing in the future.

"The purpose of this study is to examine the effect of the intervention with teaching applications of mathematics in other disciplines on teachers` attitudes towards teaching applications of mathematics. The research was conducted in the 2021-2022 school year in Israel and a two-groups pretest-posttest quasi-experimental research design was used. The participants were four classes (two of them are 11th grades and two are 12th grades) with four teachers at Al-Bukhari High School in Arraba city in northern Israel. The research instruments were three interview guides. The first interview was conducted before the intervention with all the 4 teachers and it contained 16 questions about their attitudes toward teaching mathematics and applications of mathematics. The second and third interview was similar and it was conducted during respectively after the intervention with the teachers in the experimental group. These interviews contained 5 questions related to teaching applications of mathematics in other disciplines. The results of the study showed that teaching applications of mathematics in other disciplines has a positive effect on teachers. Before the intervention, the teachers taught using the standard method, and they rarely taught applications. The teachers were not qualified enough to teach applications of mathematics and were not aware of the advantages of teaching applications of mathematics. By the intervention teachers were exposed to the inclusion of applications in teaching mathematics, and their attitudes towards teaching applications of mathematics improved and their level of confidence to teach applications increased significantly (increased from 7 to 9 on a scale from 1 to 10). That means, the intervention helped the teachers to teach the applications of mathematics successfully and with self-confidence. Furthermore, despite the difficulties and the obstacles in teaching applications of mathematics in other disciplines, teachers liked to teach the applications of mathematics and were satisfied with the results and the change among the students. They reported that they would implement the teaching applications of mathematics in other disciplines in all classes that they teach and would recommend it to their fellow teachers. Key Words: applications of mathematics, attitudes towards teaching mathematics, mathematics teachers "

Published: June 2023

The purpose of this paper is to introduce a new time-fractional heat conduction model with three-phase-lags and three distinct fractional-order derivatives. We investigate the introduced model in the situation of an isotropic and homogeneous solid sphere. The exterior of the sphere is exposed to a thermal shock and a decaying heat generation rate. We recuperate some earlier thermoelasticity models as particular cases from the proposed model. Moreover, the effects of different fractional thermoelastic models and the effect of instant time on the physical variables of the medium are studied. We obtain the numerical solutions for the various physical fields using a numerical Laplace inversion technique. We represent the obtained results graphically and discuss them. Physical views presented in this article may be useful for the design of new materials, bio-heat transfer mechanisms between tissues and other scientific domains.
Valorization of a Steel Industrial Co-Product for the Development of Alkali-Activated Materials: Effect of Curing Environments
Authors: Sarri Arezki , Oualit Mehena , Kennouche Salim
Published: June 2023

While natural resources are becoming scarce and climate change is accelerating, the recovery and recycling of wastes and by-products is an effective way to deal with the economic and ecological constraints of recent decades. The valorization of industrial by-products in civil engineering is a common practice either by their incorporation during the manufacture of Portland cements or as a partial replacement of cement during the production of concrete. The present work aims to develop waste-based alkali-activated materials WAAMs intended for civil engineering applications as a potential alternative to cement-based materials. A steel industrial by-product called commonly granulated blast furnace slag GBFS was used alone as a solid CaO-rich precursor; two alkaline activators such us sodium silicate (Na2SiO3) and sodium hydroxide (NaOH) were used separately for the production of two-part alkali-activated materials. Besides the microstructure analysis of the hardened samples, the influence of activator/precursor mass ratio, NaOH molarity, and two curing environments (Room temperature and 60°C) on the compressive strength, water accessible porosity, mass loss, and drying shrinkage were assessed. The results showed that a high Liquid/Solid ratio leads to a decrease in the compressive strength of the samples, while high NaOH molarity significantly improves the mechanical properties by reducing the porosity of the specimens. Moreover, alkaline silicate activator provides higher compressive strengths compared to the alkaline hydroxide activator, especially when the samples were cured at room temperature where a maximum 28days-compressive strength value of 105.28 MPa was achieved. For the samples activated using sodium hydroxide solution, the results revealed that their curing at 60°C promotes obtaining high initial-compressive strengths (7 days) before decreasing subsequently as a function of the curing time. As an indication, at high alkaline concentration (NaOH = 9M), a mechanical strength decline of 21% was recorded between a curing time of 7 to 28 days. Moreover, curing at 60°C induced high porosity, significant mass loss and high drying shrinkage. SEM analysis highlighted a dense, homogeneous microstructure without apparent defects, in particular for the samples where the alkali silicate activator was used.

Published: June 2023

In sheet metal forming processes, friction increases the force parameters of the forming process and produces a deterioration in the quality of the surface of the components. The basic way to reduce the unfavourable impact of friction is to lubricate the sheet metal surface with commercial oils. This article presents the results of experimental studies and analysis of variance (ANOVA) of the friction of DC01 low-carbon steel sheets using a strip drawing test. For these tests, a special device was built containing countersamples with a flat surface made of 145Cr6 steel covered with a protective AlTiN coating. Lubricants of different viscosities were fed into the contact zone under forced pressure. The effect of contact pressure on the value of the coefficient of friction was also determined. The predicted R² of 0.9227 was in reasonable agreement with the adjusted R² of 0.9411 confirming that the ANOVA model was reliable. It was found that increasing the lubricant pressure had a beneficial effect in reducing the value of the coefficient of friction. The higher the contact pressure, the more effectively the pressurised oil reduced the value of the coefficient of friction.

A Comparative Analysis of the Corporate Ideologies of Banks Operating in the Republic of Croatia
Authors: Lacković Stjepan , Baralić Marina , Šporčić Mateja
Published: June 2023

Research background

Corporate ideology is perceived as a set of fundamental beliefs held by company members about how the company and its members should behave in relation to one another and the outside world. In this paper, corporate ideology is treated as the basis for creating an organization’s identity and as an extremely important factor in its success.

Purpose

The aim of this paper is to analyze the corporate ideologies of banks operating in the Republic of Croatia, to classify different ideologies, and finally, to determine what kind of identity the surveyed banks communicate through their corporate ideologies.

Research methodology

A comparative and content analysis are applied as qualitative methods of research of an interpretative character.

Results

The corporate ideologies of two of the analyzed banks (ZABA and Erste) are described as social institutionalism, and PBZ’s ideology is labeled as social corporatism. Detected corporate ideologies do not serve to build the authenticity of banks’ identities.

Novelty

The main novelty of this research is in the methodology of reaching corporate ideologies. Unlike previous works on corporate ideology, in this paper public messages communicated in (digital) media were the main sources for the analysis of an organization’s core values and ideologies resulting from it. Also, a simple framework for the possible classification of different corporate ideologies was provided.
Confronting the Inflationary Pressures of Introducing the Euro with the Effects of Negative External Shocks
Authors: Biškupec Petra Popek , Ružić Ivan
Published: June 2023

Research background

with the introduction of the euro as the domestic currency, economies have faced inflationary pressures caused by price convergence towards higher levels. During the last period of significant negative shocks from the environment, by entering the euro area, the negative effects of the likelihood of inflation caused by the introduction of the euro may be absent.

Purpose

the aim of this paper is to prove that inflation caused by joining the euro area will not materialize due to the negative effects of external shocks.

Research methodology

A panel analysis with a fixed effects model was conducted for two models. Model 1 represents the countries that introduced the euro before the escalation of the global financial crisis and Model 2 represents the countries that introduced the euro after the development of the global financial crisis.

Results

the research confirmed that due to current negative external shocks and rising long-term interest rates in financial markets, the effect of inflation due to the introduction of the euro will be absent among EU members that will adopt the euro as a common currency in the next few years.

Novelty

The results of the research contribute to the scientific prediction of business and financial trends. The creators of macroeconomic models and monetary policy can use the results to define measures, instruments and activities more precisely for achieving and maintaining macroeconomic balance.
AD-AS Analysis from the Perspective of Functional Finance Theory and MMT
Authors: Tanaka Yasuhito
Published: June 2023

Research background

In the past few years, MMT (Modern Money Theory or Modern Monetary Theory) has been increasingly discussed in Japan as well as in the U.S. However, both in the U.S. and Japan, analysis using mathematics is lacking and analysis using IS-LM and AD-AS analysis methods in macroeconomics is almost non-existent.

Purpose

We present an AD-AS analysis from the perspective of Functional Finance Theory and MMT (Modern Monetary Theory).

Research methodology

Graphical analyses with some mathematical analyses. Mathematical analyses include graphic analysis using AD and AS curves and calculations to derive equations representing them based on models of consumer and firm behavior.

Results

Using an overlapping generations model under monopolistic competition we show the following results by calculations and graphical analyses.

1. The budget deficit (including interest payments on government bonds) equals an increase in the savings of consumers from period to period. This result means that the debt-GDP ratio would not diverge to infinity, but would remain at a finite value whether the interest rate of government bonds is larger or smaller than the growth rate.

2. We need a budget deficit (including interest payments) to maintain full employment without inflation under economic growth. However, if the interest rate of government bonds is larger than the growth rate, we need a budget surplus (excluding interest payments) to maintain full employment without inflation.

3. A return to full employment from a recession can be achieved by implementing the appropriate fiscal policies through increased government spending or tax cuts.

4. Excessive government expenditure or an insufficient tax under full employment induces inflation.

Novelty

This is probably the first AD-AS analysis done from the standpoint of Functional Finance Theory and MMT.

Donkey welfare is becoming a subject of much interest; for decades, people around the world have voiced rising worry about it. There are no studies on donkey welfare in Nigeria. This study aimed to assess the welfare state of donkeys in Amaru, Zaria Ancient City, Kaduna State, Nigeria. A cross-sectional study was done to purposefully select 38 pack donkeys for welfare assessment based on the first level of the Animal Welfare Indicators (AWIN) for donkeys, which covered behaviour, health, feeding, and environment and housing. Information regarding age and sex was collected. The analysed data were reported in terms of frequencies and percentages. The prevalence of donkeys with no social contact, avoidance behaviour, and walking downside was 2.6 %, 5.36 %, and 40.56 %, respectively. The most common health problems are integumentary alterations, which include an unhealthy hair coat (86.8 %), skin lesions (86.6 %), alopecia (60.5 %), and deep wounds (47.4 %). Only 5.3 % of the donkeys were lame. Around 42 % had a body condition score of 2 (moderate), while the remaining 57.9 % had a body condition score of 3 (ideal). The donkeys were poorly kept and housed, as evidenced by the high prevalence of unsatisfactory shelter dimensions (100 %), dirty bedding (89.5 %), and insufficient bedding (89.5 %). The current study found that welfare issues are serious challenges for donkeys in Amaru, Zaria Ancient City, Kaduna State, Nigeria. As a consequence of the current findings, it is recommended that donkey welfare, policies and legislative frameworks that support animal welfare and inspect animal facilities in Nigeria should to be reviewed and enforced.

Published: June 2023

Anak Dalam Tribe (ADT) is an indigenous community living inside the conservation area, protected as cultural heritage. ADT family is highly dependent on the forest, they used to live and fulfill all their needs from the forest. Now with the modernization and regulatory dynamics taking place, ADT family undergoes changes as a form of adaptation, leading to residing categorization i.e. traditional, transition, and bediom. The changes impact on the ecological transactions thus bring a greater potential risk of forest fires, as has happened in recent years. This study aims to discover ADT family ecological transactions based on their residing type so that potential environmental exposure can be predicted and anticipated for disaster risk reduction. The qualitative research was conducted using a cross-sectional method. Data were collected through in-depth interview, observation, and forum group discussion. Mapping was done to understand the transaction pattern. This study found that the pattern of each kampong was different, showing that development has happened following the socio-ecological changes of each kampong, either by nature or intervention from outside parties. However, the livelihood area is still the biggest and outermost area of all six kampongs despite the residing type, covering the forest area. Moreover, the area of exposure is enlarged. It vindicates the escalating disaster risk. It is suggested to create a holistic livelihood ecosystem for ADT near their residing place to minimize the disaster risk. Political identity of ADT also should be reconsidered, with the inevitable global development, how far the heritage should be kept.

Authors:   Southern Federal University, Belokrylova O.S. , Situkho A.N. ,   Southern Federal University
Published: June 2023

Parallels between the economic development of countries and the results of the actions of their elites are becoming more and more popular, which actualises the research into the areas of influence of special interest groups on the quality of institutions in different states. This study is based on the approach of methodological holism, according to which collectives are viewed as independent economic actors. The article emphasises that institutional change can occur both spontaneously and through the deliberate action of special interest groups. This essay analyses existing approaches to assessing the impact of collective actions on the historical process of institution selection, and considers the institution of power-ownership in Russia as a result of actions of special interest groups that influenced "natural" institution selection and blocked economic development of the country on this sub-optimal institution in order to maintain their redistributive advantages. The authors conclude that radical modification and destruction of this institution is necessary, but note that such changes are practically impossible on the basis of gradual reforms with an attempt to maintain a balance between all parties.

Published: June 2023

İktisadi ve istatistiksel teorilerin gelişmesi ile birlikte yakınsama hipotezleri birçok makroekonomik değişken üzerinde ampirik olarak uygulanabilmektedir. Son yıllarda ülkelerin faiz oranı, döviz kuru, işsizlik oranı göstergelerinin yanında finans sistemleri için de yakınsama hipotezinin geçerliliği analiz edilmeye başlanmıştır. Bu çalışmanın amacı, BRICS-T olarak adlandırılan/ifade edilen Brezilya, Rusya, Hindistan, Çin, Güney Afrika ve Türkiye’nin finansal gelişim seviyelerinin finans alanında başat ülke olarak kabul edilen ABD’ye ne düzeyde yakınsadıklarını analiz etmektedir. Ülkelerin finansal gelişim endeksleri temel gösterge olarak ele alınmıştır. Hipotezin geçerliliğinin sınanması için BRICS-T ülkelerine yönelik yapısal kırılmalı birim kök testleri kullanılmıştır. 1984-2020 yılları arası dönemde Brezilya 1998 yılına kadar önce yakınsama sonra ıraksama durumu içinde iken 2000 sonrası dönemde finansal yakınmasa göstermektedir. Rusya, 1990’lı yıllarda keskin kırılma yaşayarak yakınsama içinde olsa da 2000’li yıllara kadar ıraksama yaşayıp 2010’dan sonra tekrar yakınsama trendine girmektedir. Çin, Güney Afrika, Hindistan ve Türkiye genel olarak 2000’li yıllara kadar ıraksama yönünde seyir izlerken 2000 sonrasında ise finansal yakınsamanın gerçekleştiği görülmektedir. Genel olarak bütün BRICS-T ülkelerinin farklı seviyelerde de olsa 2000’li yıllardan sonra yakınsama trendine girdikleri sonucuna ulaşılmıştır.
Ruptures in Mixed Monolayers Under Tension and Supercooling: Implications for Plant Nanobubbles
Authors: Ingram Stephen , Reischl Bernhard , Vesala Timo , Vehkamäki Hanna
Published: June 2023

Mixed phospholipid and glycolipid monolayers likely coat the surfaces of pressurised gas nanobubbles within the hydraulic systems of plants. The lipid coatings bond to water under negative pressure and are thus stretched out of equilibrium. In this work, we have used molecular dynamics simulations to produce trajectories of a biologically relevant mixed monolayer, pulled at mild negative pressures (−1.5 to −4.5 MPa). Pore formation within the monolayer is observed at both 270 and 310 K, and proceeds as an activated process once the lipid tails fully transition from liquid condensed/liquid expanded coexistence to the liquid expanded phase. Pressure : area isotherms showed reduced surface pressure in the undercooled trajectory at all observed areas per lipid. Rayleigh-Plesset simulations were used to predict evolving nanobubble size using the calculated pres- sure : area isotherms as dynamic surface tensions. We confirm the existence of a critical radius with respect to runaway growth, above the homogeneous cavitation radius, coinciding with the area per lipid at which pore formation occurs.
Morphological plasticity of LiCl clusters interacting with Grignard reagent in tetrahydrofuran
Authors: de Giovanetti Marinella , Eliasson Sondre Hilmar Hopen , Castro Abril Carolina , Eisenstein Odile , Cascella Michele
Published: June 2023

Ab initio molecular dynamics simulations are used to explore tetrahydrofuran (THF) solutions containing pure LiCl, and LiCl with CH3MgCl, as model constituents of the turbo Grignard reagent. LiCl aggregates as Li4Cl4, which preferentially assumes compact cubane-like conformations. In particular, an open-edge pseudo tetrahedral frame is promoted by solvent-assisted Li-Cl bond cleavage. Among the Grignard species involved in the Schlenk equilibrium, LiCl prefers coordinating MgCl2 through m-Cl bridges. Using a 1:1 Li:Mg ratio, the plastic tetranuclear LiCl cluster decomposes to a highly solvated mixed LiCl·MgCl2 aggregate with prevalent Li-(m2-Cl)2-Mg rings and linear LiCl entities. The MgCl2-assisted disaggregation of Li4Cl4 occurs through transient structures analogous to those detected for pure LiCl in THF, also corresponding to moieties observed in the solid state. This study identifies a synergistic role of LiCl for the determination of the compounds present in turbo Grignard solutions, in a scenario where LiCl shifts the Schlenk equilibrium promoting a higher concentration of dialkylmagnesium, meanwhile decomposing into smaller, more soluble, mixed Li:Mg:Cl clusters.
Serendipitous Triplet Harvesting in Donor-acceptor Dyads with Low Spin-orbit Coupling
Authors: Karak Pijush , Moitra Torsha , Banerjee Ambar , Ruud Kenneth , Chakrabarti Swapan
Published: June 2023

Here, we present a heuristic mechanism for efficient intersystem crossing (ISC) between singlet and triplet states with low spin-orbit coupling (SOC) in molecules having donor-acceptor (D-A) moieties separated by a sigma bond. We show that SOC between the first singlet and the higher-lying triplet states, together with nuclear motion-driven coupling of this triplet state with lower-lying triplet state during the free rotation about a sigma bond is the only plausible way to achieve the experimentally observed ISC rate for a class of D-A type photoredox catalysts. We found this mechanism to be the dominant contributor to the ISC process with the corresponding rate reaching maximum at an optimal dihedral angle between D-A moieties. An extension to this is provided by discovering the same mechanism to be operative in a specific spirobis[anthracene]diones molecule where the D and A moieties are interlocked near to the optimal dihedral angle, indicating the plausible universality of the proposed mechanism. The present finding is expected to have implications in strategies for the synthesis of a new generation of triplet-harvesting organic molecules.
Las normas como herramientas de combate
Authors: Paredes Martínez Roger
Published: June 2023

Tras la implementación de políticas para la liberalización de la economía peruana en la década de 1990, el país experimentaría un notable incremento en su recaudación fiscal. Esto permitió la realización de diversas obras públicas, especialmente por parte de los gobiernos locales, las cuales generaron réditos políticos hacia las figuras de diversos alcaldes que hallaron un creciente respaldo entre la población. No obstante, esto implicó el surgimiento de recelos en el seno del gobierno central, el cual se valdría de la promulgación de diversas normas tendentes a perjudicar la recaudación y financiación de los gobiernos locales, sin reparar en las repercusiones negativas que las mismas tendrían en la población, especialmente entre los más necesitados.
Corporate digitalization in the european context: going one step further
Authors: Galeote Muñoz María del Pilar
Published: June 2023

The digitalization of corporations is on the right path; however, the advantages sought by that process could be overshadowed by the disadvantages that come with any technological process. The aim of this work is to make a careful analysis of the framework set out by the lawmakers through Directive (EU) 2019/1151 of the European Parliament and of the Council, of 20 June 2019, amending Directive (EU) 2017/1132 as regards the use of digital tools and processes in company law, and, based on the principles governing corporate digitalization, take the analysis one step further, indicating where this issue should go in the future. Although technology helps corporations, its indiscriminate use in the corporate sphere could lead us to a European model of capital company that bears no resemblance to the one we have now. It is a process in which more advanced technology should be introduced progressively, in order to discover gradually how appropriate or not its adaptation is. This opens up a huge potential for modernizing corporate law that we should take advantage of – with caution and security – but to the fullest.

Neoklasik Realist Teori Perspektifinden Türkiye’nin 1956 Süveyş Krizi’ne Yönelik Dış Politikasının Analizi
Authors: GÜNDOĞDU Emre , KAYA Onur
Published: June 2023

Bu çalışma Türkiye’nin 1956 Süveyş krizi konusunda yürüttüğü dış politikayı neoklasik realist teori çerçevesinde analiz etmektedir. Bu doğrultuda, bir bağımlı değişken olarak “1956 Süveyş krizine yönelik Türk dış politikasını” analiz etmek için, çalışmanın metodolojisi gereği, “uluslararası sistemsel faktörler” bir bağımsız değişken ve “yerel faktörler” bir ara değişken olarak ele alınmaktadır. Çalışmada 1956 Süveyş krizine yönelik Türk dış politikası yapımı sürecinde belirleyici/sınırlandırıcı bir etkiye sahip olduğu öne sürülen uluslararası sistemin yapısı, Soğuk Savaş döneminde süper güçler arasındaki ideolojik karşıtlık ve nükleer rekabeti ifade eden iki kutupluluk ile ilişkilendirilerek açıklanmaktadır. “Caydırıcı askeri kapasite ihtiyacı”, “Türk dış politikası geleneğindeki Batıcılık eğilimi”, “ekonomik teşvik gereksinimi” ve “karar alıcıların bölgesel liderlik çabası” gibi çeşitli faktörler ise uluslararası sistemin belirleyici/sınırlandırıcı etkilerini yorumlayıcı nitelikteki yerel filtreler olarak ele alınmaktadır. İki farklı analiz düzeyinin kullanıldığı bu çalışmada hem 1956 Süveyş krizine yönelik Türk dış politikasının sistemsel etkilere dayanan “sürekliliği” hem de yerel dinamiklerden kaynaklanan “değişim eğilimi” ortaya konulmaktadır.
