The family business failure paradox in the retail industry: Does succession planning contribute to the preservation of superior performance?
Authors: Gichuki Fredrick Gitahi , Ábel István
Published: October 2023

Family firms have continued to register low survival rates. Across the world, research puts the survival rate of family businesses beyond the third generation at a mere single digit. The dilemma is also that despite the high failure rate of family-owned firms, the world’s most enduring companies also belong to this class. What do they do differently from the majority of their peers? Succession planning tops the list of the 21st century’s paradoxical challenges facing family business enterprises. Past studies have been barely conclusive on whether and how succession planning, or the lack of it, affects business economic performance. The current study assesses the effect of succession planning on business economic performance. The study used a deductive approach, a survey research strategy, and an explanatory research design to fulfil its objectives. Data analysis was done through descriptive as well as inferential analyses. Regression analysis results indicated that succession planning is a statistically significant determinant of business economic performance. The study recommends that firms should improve their measures targeted towards the prior identification of roles and leadership positions that require successors. The study also recommends the enhanced preparation, grooming, and development of identified successors.

Published: October 2023

Literacy is defined as the ability to read, write and a person's ability to see the world and store information. The library is an effort to support education by providing teaching resources, information and references. During the Covid-19 pandemic, it was reported that there was a decrease in visits to the library. Like libraries in other areas, Muda Bhakti library located in Ngablak Village, Srumbung District, Magelang Regency, Central Java has also reportedly experienced a decrease in visitors during the Covid-19 pandemic. It is necessary to make innovations and concrete programs that are in accordance with the situation and conditions of the local community, especially targeting children, considering children are easy targets to be educated in an interesting way. The purpose of this community service is to carry out a children's literacy movement through the reactivation of the Muda Bhakti library during the Covid-19 pandemic. There are five main programs carried out in this service, namely 1) socialization of health protocols at the Muda Bhakti library during the Covid-19 pandemic, 2) hand washing practices according to WHO standards, 3) group learning for children in the library, 4 ) competitions in the form of writing short stories and coloring, 5) donations and book processing. The methods used to run the program are lectures, demonstrations and practice. This activity was attended by children from kindergarten to elementary school with a total of 60 children. This community service expected that it will be able to increase the literacy capacity of children during the Covid-19 pandemic.

Children who lack motivation and interest in learning and reading often demonstrate apathy and are easily discouraged, leading to a lack of concentration on their educational pursuits. As a result, these students face challenges in their academic journey. Therefore, it is crucial to make concerted efforts to enhance children's literacy by implementing the reading aloud approach, which can positively influence their overall growth and development in the Rusunawa Ciseureuh Purwakarta community. The primary objective of this program is achieved through the utilization of the reading-aloud technique. The anticipated outcomes of this program encompass increased children's motivation and interest in literacy, which will be supported by supplementary elements such as incorporating enjoyable learning techniques, engaging in gardening activities, decorating pots, and providing incentives for participating children.
Affective Cartographies of Collective Blame
Authors: Trnka Susanna , Wynn L. L.
Published: October 2023

In both Aotearoa/New Zealand and Australia, COVID-19 lockdowns were enforced through public scrutiny of the movements of supposedly ‘irresponsible’ individuals. Denouncing their impact on public health created an affective cartography of collective blame uniting State and society in shared moral indignation. Produced through assemblages of mainstream and social media and government statements, such mediated spectacles engendered a sense of collective unity and shared purpose at a time when both collective cohesion and narratives of individual responsibility were of particular interest to the State. Spatio-temporal maps and diagrams of culpable contagion helped materialise the invisible movement of the virus but also enabled identification of the sick. Some bodies more than others were made to carry the morality of the collective enterprise of stopping the virus.
Marginalised People's Access to Publicly Funded Abortion in Catalunya
Authors: Ostrach Bayla
Published: October 2023

Abortion has been legal in Catalunya for any reason in the first trimester and under a set of qualifying circumstances in the second since 2010 and integrated in the health system. Earlier studies identified disparities in access. Through rapid ethnographic assessment (REA) at a Barcelona clinic, this study sought to compare the findings of an earlier phase of REA previously published in this journal with subsequent data collection to determine continuity or changes in accessibility of publicly funded abortion. A subsequent REA found similarities in average wait times and numbers of visits to obtain the required voucher for a publicly funded abortion. Also persistent were greater delays for migrants. The greatest difference was participants with notably later average gestations when obtaining publicly funded abortions.
Zakres podmiotowy i przedmiotowy kościelnych regulacji dotyczących ochrony danych osobowych. Glosa do postanowienia Wyższego Sądu Krajowego w Hamm z dnia 23 września 2022 roku, 26 W 6/22

Przedmiotem opracowania jest analiza postanowienia Wyższego Sądu Krajowego w Hamm z dnia 23 września 2022 r. (26 W 6/22) i poprzedzającego go w I instancji postanowienia Sądu Krajowego w Siegen z dnia 26 listopada 2021 r. (2 O 236/21), dotyczących dopuszczalnego zakresu podmiotowego i przedmiotowego kościelnych aktów prawnych z zakresu ochrony danych osobowych. Analizie poddano stanowisko sądów państwowych odnoszące się do dopuszczalności stosowania kościelnych regulaminów ochrony danych osobowych w podmiotach medycznych prowadzonych przez kościół, a także w odniesieniu do poboru podatku kościelnego. Wykazano, że judykatura aprobuje szeroki zakres podmiotowy i przedmiotowy regulaminów kościelnych, co ma bezpośredni wpływ nie tylko na ukształtowanie konkretnych praw przysługujących osobom, których dane są przetwarzane, ale także na właściwość organów nadzorczych. Porównywalny do RODO poziom ochrony danych osobowych przewidziany w kościelnych aktach prawnych realizujących uprawnienie kościoła lub innego związku wyznaniowego, określone w art. 91 ust. 1 RODO, skutkuje akceptacją dla szerokiego zakresu podmiotowego i przedmiotowego tych aktów oddziałujących także na prawa osób niebędących członkami danego kościoła lub innego związku wyznaniowego. Aprobata dla takiego rozwiązania wynika nie tylko z istniejących unormowań prawa konstytucyjnego i samego art. 91 RODO, ale także z istotnego podobieństwa kluczowych unormowań kościelnych regulaminów ochrony danych do rozwiązań RODO.
Contours of the Migration Crisis of 2020–2022 in Russia
Authors: Shustov Alexander
Published: October 2023

The migration situation in Russia during the COVID-19 pandemic has a number of signs of a migration crisis. The understanding of this phenomenon, which has developed under the influence of the migration crisis of 2014-2015 in the EU countries, is usually associated with the influx of large masses of migrants to a limited territory for a short period of time. In Russia, the crisis phenomena in the migration sphere during 2020 – early 2022 were caused by the closure of borders and the difficult socio-economic situation in which labor migrants from Asian CIS countries who were in the Russian Federation found themselves. However, the prerequisites for this crisis were formed during at least the second half of the 2010s. In many ways, they were associated with a noticeable increase in the volume and change in the ethnic structure of migration flows in favor of immigrants from Central Asian countries. At the same time, there was a decrease in the number of labor migrants from the European CIS countries – Ukraine and Moldova, who received the opportunity to work legally in the EU countries after signing Euroassociation agreements in the mid-2010s. Due to the vast territory of Russia and the unevenness of its economic development, the features of the migration crisis were mainly local in nature and were most clearly manifested in the most attractive regions for migrants – Moscow, St. Petersburg and adjacent areas. Its manifestations were mass protests, riots and conflicts involving migrants, as well as a noticeable aggravation of their relations with employers, authorities and the local population.
Territorial Identity: Structure, Boundaries, Reproduction (A Comparative Analysis of the Saratov region, the Republic of Kabardino-Balkaria and the Republic of South Ossetia)
Authors: Mokin Konstantin S. , Baryshnaya Natalia A.
Published: October 2023

The purpose of the article is to analyze the phenomenon of territorial identity as a reflection of modern transformation processes and a relevant indicator of the potential for social mobilization of residents of local territories. The research objectives were to analyze the structure of territorial identity, the forms and mechanisms of reproduction of the external and internal social boundaries of the territorial identity area, and the role of social networks in its reduction. The analysis of the data is based on sociological studies conducted in the Saratov region, the Kabardino-Balkar Republic, and the Republic of South Ossetia. It describes the structural characteristics of territorial identity, the processes of formation of its social boundaries, and evaluates social networks as tools for its preservation, formation, and transformation. The authors conclude that territorial identity occupies a leading place in the structure of an individual self-identification and can be a powerful group consolidating factor.
Paradoxes of the Russian Popadanets` Science Fiction
Authors: Latov Yuri
Published: October 2023

The author supports proposed by R.N. Abramov interpretation of the Russian science fiction development in the genre of alternative history as a reflection of the mass consciousness dynamics of Russians, but attempts, taking into account bibliometric data, to significantly clarify it. The development of this genre should be seen in the context of the evolving historical mentality of "post-Soviet" Russians, which turned out to be characterized by a commitment to virtual versions of historical events. This finds expression in the mass popularity of not only pseudo-scientific literature on the topics of Russian history (for example, so called “new chronology”), but also frankly fantastic “popadanets`s” alternative history. The perception of many periods of Russian history as a trauma that one would like to get rid of by rewriting or “replaying” real events is, to a large extent, a projection onto the past of the critical attitude of many Russians to the post-Soviet present. The decisive motive in this case is a desire for revenge - to change the results of historical events that were unsuccessful for Russia (first of all, military defeats).
Russian Sociology in Search of Responces for Theoretical Challenges
Authors: Titarenko Larisa G.
Published: October 2023

Any social science needs is a theory as its integral part. Since 2022, Russian sociology has existed in the context of new challenges and social threats related to Russia's intentions to change the global balance of power. New conditions stimulate a revision of approaches to solving key problems of society and making adjustments to the theoretical models of its development. This is in many ways a painful process requiring intellectual efforts and political decisions. Since we are talking about Russian sociology, it is necessary to rethink the existing Russian macrotheories. There is an active search for new ways of developing social science. The search for these paths is accompanied by a rethinking of the well-known "universal" ways of modernizing society, which will help Russian sociology to determine its place in the global scientific community, while preserving its own cultural heritage. The article analyzes which theories can be considered relevant in Russia today, focusing on nodernization schemes and civilization approach developed by Russian sociologists, in particular, by Nikolay I. Lapin.
How to Get Truthful Answers in Sensitive Research (On the methodological potential of the nominative techniquе)
Authors: Myagkov Alexander Yu.
Published: October 2023

The article is devoted to the description and analysis of the nominative technique, which belongs to the class of non-randomized survey models designed to obtain sincere answers from respondents in research on sensitive issues. Theoretical origins and methodological foundations of the nominative technique are analyzed. Its connection with the methods of multiplicity and the theory of network samples by M. Sirken is traced. A detailed description of the two main versions of the analyzed technique is given: the early one, presented by the «three closest friends of the respondents» method, proposed in the 1970s byM. Sirken, and the later, developed by J. Miller in the middle 1980s taking into account the volume and depth of the respondents' social networks, as well as information about the deviance of «significant others». The organizational, technical and methodological features of these versions are shown. Methods for statistical assessment of the prevalence of the studied types of social deviations for both described models are presented. The advantages and disadvantages, possibilities and limitations of the nominative technique, as well as the conditions for its reliable application are discussed. The results of empirical studies are presented, indicating the superiority of this technique over the self-report method in terms of the reliability and quality of the data obtained. The conclusion is made about the expediency of its use when discussing sensitive issues and topics with respondents.

On the Regional Consciousness of the Russian-Chinese Border Region Students
Authors: Simonyan Renal'd Kh.
Published: October 2023

In the modern world, the intensity of interstate interactions is increasing. Of great importance in this process are the territories where these interactions take place in the forms of contact – border regions. For Russia, located on two continents, in which more than half of the regions are border regions, this is especially important. Due to the shift of the world economy center towards the Asia-Pacific region and the growing of economic cooperation between Russia and China, the Russian-Chinese border area and, above all, its social component, is becoming an actual object for Russian sociology. The study of consciousness – individual, group, social – is important, both in theoretical and in practical aspects, because people's actions are a product of their thoughts and feelings. This also applies to regional consciousness, a form of perception of group community based on the unity of the territory, which emphasizes the context of the sociology of space. Based on the empirical basis of a survey conducted in December 2021, the article presents the results of a comparative analysis of the regional consciousness of university graduates of the Russian-Chinese border region, confirming the multiplicity of regional consciousness, which manifests itself in homogeneous groups of the population living in the same natural and social conditions. The conclusion is substantiated that it is necessary to study specific forms of regional consciousness in order to expand the theoretical basis for Russia's regional policy.

Stepped Hulls Early Stage Design by Implementing 2D+T Method
Authors: Niazmand Bilandi Rasul , Dashtimanesh Abbas , Tavakoli Sasan
Published: October 2023

This paper uses the 2D+T method for hull optimization of double-stepped planing hulls at the early-stage design. The method is applied to investigate the impact of various step configurations on the performance of stepped planing hulls in calm water and waves. The 2D+T method utilizes pressure distributions along the hull length to calculate forces in calm water and incorporates momentum variation theory to mathematically simulate rigid body motions in waves. Previous studies have validated the accuracy of this method. The paper conducts a parametric study on a double-stepped hull, analyzing the effects of different step configurations on hydrodynamic performance in calm and rough water conditions. The results suggest that optimal location of front step is somewhere near the mid-section, and that of rear step is in the vicinity of the center of gravity for steps with identical heights. It is demonstrated that this configuration minimizes the added resistance and wave-induced motions. It is concluded that the 2D+T method can effectively assist designers in hull optimization of stepped planing hulls in the early-stage design. Further research is recommended to consider the effects of step shape in the hull optimization.
A Fast Numerical Procedure to Design the Shaftline Struts
Authors: Bozzo Simone , Villa Diego
Published: October 2023

The “design spiral” of a new ship consists of various milestones, one of them dealing with resistance prediction of the fully appended hull and with the proper placement of appendages, especially in the stern part of the ship where a complex 3D flow grows up. Applying an open-source code, the Open-Source Field Operation And Manipulation (OpenFOAM) one, in this paper it’ll be shown a fast numerical, robust and user-friendly procedure for the designers to achieve struts proper alignment rather than rely on a traditional more expensive, both in time and costs, Experimental Fluid Dynamics test campaign. An open-access data of a twin-screw propellers ship, the David Taylor Model Basin (DTMB) 5415, has been here considered to carry out the Fast Procedure. Once the test case has got through the Verification and Validation procedure, different kinds of simulations have been performed to assess that a Double Model simulation with the effects of trim, sinkage and propellers can describe with an adequate degree of accuracy the orientation of the field. It has been possible to carry out this last assessment through the generation of a cloud of points next to the struts position to obtain the orientation of the field and evaluate the difference between simulations. Two substantially hydro-dynamically equivalent approaches have been considered to design new struts in order to minimize their interactions with the hull and other appendages. Through the use of this Fast Procedure, the design time is evaluated equally to a few days, and it can be performed without specific knowledge or huge computational resources and so it can be considered industrially affordable.
Prediction of Manoeuvring Characteristics in the Concept Design of a Destroyer
Authors: Ambrosino Leonardo , Braidotti Luca , Bertagna Serena
Published: October 2023

Manoeuvring is one of the fundamental qualities of the ship. It has a direct impact on the operability of the unit and therefore on the shipowner’s perception of quality. Furthermore, the manoeuvrability forecasting models are extremely sensitive to the geometry of the hull and appendages and thus closely related with the type of the unit. In this article, an innovative methodology for predicting the manoeuvring characteristics during the conceptual design phase is presented. It may be applied to all types of vessels, especially those requiring a specific study of manoeuvrability, such as fast hulls. Here, a destroyer has been considered. Starting from 15 hulls geometries, a fleet of 225 ships has been generated, by changing systematically the ratio L/B, B/T and the block coefficient CB. This way a 3-dimensional Central Composite Circumscribed (CCC) has been obtained, that comprehends a total of 15 experimental points for each base hull. Manoeuvring calculations has been performed on each vessel of the fleet and the main manoeuvring dimensionless quantities has been related to some simple variables, known during the conceptual phase. With a greedy approach, the adjusted coefficient of determination R‾2 has been maximized. This way, from the collected data, the best possible linear models for manoeuvring characteristics are obtained. This is because no statistical significance filtering of the variables is performed, as instead happens in the classic stepwise approach.
Feasibility Study for the Fuel Switch of a Fast Ferry
Authors: Padolecchia Donato , Utzeri Samuele , Marinò Alberto , Bucci Vittorio
Published: October 2023

Liquefied Natural Gas (LNG) has recently become a popular fuel in the shipping industry due to its low emissions and high energy density. However, it requires one or more bulky cryogenic tanks for storage onboard. Considering a traditional fast ferry, it is hard to find onboard a location for tanks, thus hindering the retrofit of existing ships. In this context, Compressed Natural Gas (CNG) might be a viable solution, since it can be more flexibly stored onboard and has greater availability in minor ports compared to LNG. Hence, this article investigates the feasibility of retrofitting the propulsion system of a fast ferry to employ CNG as fuel. After a review of the pros and cons of CNG and LNG as alternative fuels to marine diesel oil (MDO), a critical analysis of the technical requirements for retrofitting a fast ferry with CNG propulsion systems is carried out. Defined the layout and changes of the refitted unit, its performances are assessed on a test operative scenario. The study concludes that CNG retrofitting is technically feasible and provides several benefits, including lower emissions, higher levels of performance and higher reliability compared to LNG. Nevertheless, the retrofit requires significant changes to the ship layout and its fuel system to fit the required number of CNG cylinders.
Surf-Riding of Ships from the MARIN Series of Fast Displacement Ships
Authors: Ilić Nemanja , Bačkalov Igor
Published: October 2023

The paper employs the Second Generation Intact Stability Criteria (SGISC) Vulnerability level 2 to investigate the vulnerability of the MARIN series of fast displacement ships to surf-riding. Additionally, the paper examines the influence of different options for ship resistance and wave surge force calculation on the outcome of the vulnerability assessment. The results indicated the limiting size of the ships in the series for which the surf-riding became the design constraint. Furthermore, it is shown that while the ship resistance estimation method might not have a considerable influence on the surf-riding vulnerability assessment, the impact of accounting for effects of diffraction in the wave surge force could be significant.
Energy Balance Approach for Studying Waterjet-Hull Interaction Effects
Authors: Eslamdoost Arash , Vikström Marko
Published: October 2023

Waterjet-hull interaction effects are usually studied by analyzing hull attitude in the presence of a waterjet unit as well as the counteracting resistance and thrust forces. Since the waterjet unit is integrated with a hull, net thrust cannot be accurately measured. Instead, it is suggested to use an alternative measurable thrust, gross thrust, to study the interaction effects. Gross thrust is the momentum flux change through the waterjet unit and is calculated by obtaining axial velocity distribution at the inlet to the waterjet unit and the nozzle outlet. However, this approach does not provide detailed information about system power consumption. In this paper, a more comprehensive method is suggested in addition to the momentum flux approach. The method is based on the investigation of energy flux through the waterjet system. This approach not only enables us to qualitatively describe the flow but also makes it possible to quantify different energy flux components and understand the energy loss mechanisms within a waterjet system. The required flow quantities for this analysis are obtained from a Reynolds-Averaged Navier-Stokes approach together with a Volume-of-Fluid method for capturing the free surface. The transport equation for energy is also solved for obtaining the viscous losses in the form of internal energy increase in the flow. The sum of mechanical and thermal energy components computed by analyzing energy flux through the waterjet system deviates less than 0.5% from the pump-delivered power. This confirms the capability of the proposed method for capturing the decomposition of different energy components in the flow. Further analysis of the decomposition of energy flux through the waterjet system is carried out to identify the loss components in the flow.
A multiple case study of preservice music educators' experiences in rehearsal clinic
Authors:   , Davis Allison Rachel
Published: October 2023

The purpose of this qualitative multiple case study was to describe the experiences of preservice music educators in an advanced conducting and rehearsal skills course. Additionally, I explored preservice music educators' perceptions about the intersections of conducting ability, rehearsal skills development, and their effectiveness as a music educator. The primary research question that guided this study was: What are the perceptions of preservice music educators regarding their conducting and rehearsal experiences as a result of an advanced conducting and rehearsal skills course? Further, two sub-questions provided depth and additional insight about preservice music educator development: (a) How do these students view their conducting ability, rehearsal skills development, and effectiveness as a music educator? and (b) Does participation in an advanced conducting and rehearsal skills course influence preservice music educators' perceptions about their teacher effectiveness? If so, in what ways? Participants in this study were four preservice music educators in at least their third year of study in their music education degree program who were enrolled in Rehearsal Clinic. Findings indicated all four participants (a) believed there to be a clear difference between rehearsing and teaching, (b) encountered conductor "blackout" while teaching a large ensemble, and (c) attributed the perceived growth in their teacher effectiveness to their experiences in the course. Furthermore, findings from this study may suggest that music teacher educators should consider including more frequent large ensemble teaching opportunities within collegiate curricula prior to field experience and student teaching.

Published: October 2023

With the Asian Hate outbreak during the COVID-19 pandemic, East Asian international students experience more overt racial discrimination and attack while seeking education afar from home. Despite the increased emphasis on social justice and multiculturism in the educational program development, East Asian international students may have more experiences of isolation, alienation, and marginalization due to their accent, skin color, ancestry, and religion, which is similar yet distinctive compared to that against racial minorities in the United States. The current study examined factors that contribute to these students' academic satisfaction, based on the well-being model of Social Cognitive Career Theory. Perceived discrimination was used as an environmental barrier in the model as its relevance to these students. Data from 324 East Asian international students (Mage = 22.30, SDage = 4.82; nfemale = 155, nmale = 162) were collected through Qualtrics. Multigroup measurement invariance and multigroup structural equation modeling were used to examine the gender differences in measurement constructs and relationship. The result showed that two gender groups were equivalent at the scalar level and the proposed model fit the data in two sample groups well. Significant gender differences in several latent factors and pathways were observed. Implications, limitations and future research were discussed.
Random sections of star bodies

This thesis concerns analytic and geometric aspects of random sections of star bodies and their implications for problems in stochastic geometry. We treat isoperimetric inequalities and distribution of volumes of such sections. In particular, we resolve a longstanding conjecture on affine isoperimetric inequalities in Lp spaces. The first part of this work is dedicated to the study of isoperimetric inequalities of dual centroid bodies. This family interpolates between the Busemann intersection inequality and the Lutwak-Zhang inequalities, two fundamental affine isoperimetric principles. Consequently, we establish new bridges between Brunn-Minkowski and dual Brunn-Minkowski theories that handle both through a uniform treatment. The approach relies on a new family of random star bodies. The second part concerns limit theorem for sections of star bodies. We establish Central Limit Theorem (CLT) for the volumes of intersections of Bnp with uniform random subspaces of codimension d for fixed d and n --> [infinity]. We refine previous estimates for expected volumes of Koldobksy and Lifshits for 0 < p < 1 and the approximation obtained by the Eldan-Klartag version of CLT for general convex bodies when 1 [less than or equal to] p < 2. In the last part, we provide a short alternative proof of the Busemann intersection inequality. The approach depends on a randomized approximation inspired by a construction of Anttila, Ball, and Perissinaki.
Romantic love, romanticism, and Romeo and Juliet : authentic mimesis of emotion in music
Authors:   , Beran Lauren
Published: October 2023

Since ancient times, music has been utilized by humanity as an almost divine manipulator of the senses and emotions. Its evolution throughout history can be tracked in multiple ways, though one sticks out. Romeo and Juliet, a practically globally known tale, prominently links the Renaissance to the Romantic era and beyond, arguably the greatest reason for this being Shakespeare's exploration of how love, the most potent and complex emotional state, transcends both life and death. Drawing upon Shakespeare's own use of music for sensory manipulation as well as the original Greek philosophies of music, Romantic composers achieved the most authentic imitations of love, communicated to audiences by way of the star-crossed lovers.
A literature review of stimulus control and fading discriminative stimuli
Authors:   , Dultz Ethan John
Published: October 2023

A multiple schedule is a compound schedule in which two or more component schedules of reinforcement, extinction (EXT), or punishment are alternated based on the passage of time; each component is correlated with a unique stimulus. This review summarizes the stimuli used within a multiple schedule. Thirteen studies were identified through a systematic search process and several different characteristics were evaluated. The variables evaluated were the types of stimuli used, the extension of findings to other settings or people, and if the stimuli were faded. The discussion consists of the findings, implications, and recommendations for future researcher

Published: October 2023

To further optimize [99mTc]Tc/Re-tricarbonyl-NOTA complexes as potential theranostic agents, here we present the synthesis and evaluation of 1,4,7- triazacyclononane (TACN) chelators having different pendant arm functionalities. Briefly, we report the metal complexes of the general formula fac-[M(CO)3(L)]+ (M=Re, 99mTc), where L indicates the different TACN chelators bearing different pendant arm functionalities. Three new bifunctional chelators, namely, NOTAM-BA (TACN with two acetamide arms and one benzylamine arm), NOTAL-BA (TACN with two ethyl alcohol arms and one benzylamine arm), and NOTACE-BA (TACN with two acetone arms and one benzylamine arm), in addition to the existing chelator NOTA-BA (TACN with two acetic acid arms and one benzylamine arm), were successfully synthesized and characterized. Since this is a fundamental science project, we have used chromophore-containing group benzylamine (BA) as a biomolecule surrogate. The complexation of the chelators was explored with fac- [99mTc][Tc(CO)3]+ and fac-[Re(CO)3]+ cores. NOTA-BA, NOTAM-BA, and NOTALBA formed complexes with [99mTc]Tc/Re-tricarbonyl cores. The corresponding Re complexes, namely, [Re(CO)3(NOTA-BA)]+ (Re-1), [Re(CO)3(NOTAM-BA)]+ (Re- 2), and [Re(CO)3(NOTAL-BA)]+ (Re-3) were purified in small batches using multiple xiii HPLC runs and characterized spectroscopically. The [99mTc]Tc-tricarbonyl labeled complexes [99mTc][Tc(CO)3(NOTA-BA)]+ (Tc-1), [99mTc][Tc(CO)3(NOTAM-BA)]+ (Tc-2), and [99mTc][Tc(CO)3(NOTAL-BA)]+ (Tc-3) were prepared in 92 percent, 40 percent, and 27 percent radiochemical yields, respectively (observed by radio-HPLC analysis) by reacting the chelators NOTA-BA, NOTAM-BA, and NOTAL-BA with [99mTc][Tc(OH2)3(CO)3]+. Under comparative HPLC studies, these radiotracers correlated well with their respective natural rhenium-labeled standards (Re-1, Re-2, Re-3). All 99mTc-labeled complexes remained stable through 18 h against challenge experiments with 1 mM L-cysteine and 1 mM L-histidine. Stability studies showed that the radiotracers remained stable through 18 h in rat serum. The log D7.4 values indicated that [99mTc][Tc(CO)3(NOTA-BA)]+ was more hydrophilic than [99mTc][Tc(CO)3(NOTAM-BA)]+ followed by [99mTc][Tc(CO)3(NOTAL-BA)]+. These findings establish that the [M(CO)3]+ complexes of NOTA-BA, NOTAM-BA, and NOTAL-BA are stable under in vitro challenge experiments and are hydrophilic in nature. In the future, labeling of the model bifunctional chelators with [186Re][Re(CO)3]+ can be explored. After that, the Log D7.4 studies and stability of the corresponding 186Re labeled complexes can be tested under challenge experiments.
Engaging diverse high school student through a deliberative climate change forum

Climate change is the most pressing environmental issue in the 21st century. Its effects increase in severity due to human actions that negatively impact natural resources. This produces risks to human health, food security, water supply, and the global economy. In order to address climate change, it is crucial to recognize it as a social-environmental issue. Formal and nonformal education plays an important role in fostering knowledge, attitudes, values, and behavior among students. Thus, it is essential to prioritize education and research that explores differences in knowledge and attitudes toward climate change among diverse high school populations. For that reason, this study aims to engage diverse high school students in Missouri through a deliberative climate change forum. This study was conducted using a mixed-methods approach with students from 2 different Missouri high schools (n=22). The quantitative approach included pre and post-test instruments, while the qualitative procedure was a focus group using the Climate Choices Issue Guide created by the North American Association for Environmental Education (NAAEE). The deliberative climate change forum was divided into five sections: recognition, reduction, adaptation, innovation, and conclusion, with 17 questions in total. Paired-sample tests showed a statistically significant increase in knowledge (t(21)=- 2.806, p=0.005), awareness (t(21)=-6.21, p<0.001), and hope (t(21)=-3.65, p<0.001) after the forum. The students were able to identify what are the causes, and consequences of global warming, and got a better understanding of climate systems. Additionally, participants provided strategies that they considered the most effective ways to address climate change. This suggests that climate change education and deliberative forums can foster awareness about environmental issues and promote positive values and attitudes towards climate change.
