"all the appearances of being innovative": New Zealand architecture in the 1970s
Authors: McCarthy Christine
Published: August 2022

Mike Austin's seemingly faint praise, in a 1974 review of a medium-density housing development, that the architecture had "all the appearances of being innovative," is echoed in Douglas lloyd Jenkins' observation that: "Although the 1970s projected an aura of pioneering individualism, the image disguised a high degree of conformity." The decade's anxious commencement, with the imminent threat of the European Economic Community (EEC) undermining our economic relationship with "Mother Britain," was perhaps symptomatic of a risqué appearance being only skin deep. Our historic access to Britain's market to sell butter and cheese was eventually secured in the Luxembourg agreement, which temporarily retained New Zealand trade, but with reducing quotas, as a mechanism to gradually wean New Zealand's financial dependency on exports to Britain.
Code-switching in the TEFL Undergraduate Classroom. (c2022)
Authors:   ,   Lebanese American University, Al Chal Sandra
Published: August 2022

Code-switching is the usage of two or more languages when speaking and it happens mostly in communities that are bilingual. This paper is an exploratory qualitative study which focuses on code-switching in TEFL undergraduate courses at a private university in Lebanon. The aim of this study was to discover teachers’ perceptions and practices regarding code-switching in first and second year TEFL major classrooms at a university in Lebanon. It also investigated students’ perceptions regarding code-switching in the first-year undergraduate TEFL major in the university. The study attempted to see whether teachers and students perceive code-switching as a beneficial tool in the classroom or not. The four instructors of the first and second year TEFL undergraduate courses were interviewed using in-depth interviews. Their classrooms were observed three times using non-participant observations. The students were also interviewed using focus-group interviews. The findings of this study supported the view that code-switching in the language classroom is a facilitating tool for the students. The findings also showed that switching to the native language should be allowed only in certain situations when it is needed and that it has many benefits for the students, as supported by previous findings. However, further research should be conducted in more than one campus of a university and with larger number of participants in order to get a wider view of the Lebanese context. In addition, longitudinal studies should be conducted to see the difference between the levels of code-switching at the beginning of the semester and at the end of it.
Success and Failure of Revolutions in Lebanon. (c2022)
Authors:   ,   Lebanese American University, Nader Sarah
Published: August 2022

On October 17, 2019 thousands of people took to the streets all over Lebanon to protest against the economic situation and the corrupt practices of the Lebanese government and Lebanon’s ruling elite. The protestors called for the resignation of the Lebanese parliament, the cabinet and the president of the republic whom they accused of bearing responsibility for the economic crisis gripping the country. The protesters further demanded the introduction of major political and socioeconomic reforms. Only a few of the objectives of the protestors were met. A few months after its onset, the “October 17th Revolution” lost its momentum and the economic crisis in Lebanon intensified. This thesis aims to understand why Lebanon’s “October 17th Revolution” failed to achieve most of its objectives although, at the outset, several political observers expected it to succeed. This thesis further investigates two prior revolutions that can be considered successful ones: the 1952 revolution (that ousted then President Bishara El-Khoury) and the 2005 Cedar Revolution that led to the withdrawal of the Syrian army from Lebanon. The thesis contends that by comparing these two past revolutions with the “October 17 Revolution”, one can identify the factors that were responsible for the failure of the “October 17 Revolution”. These factors can be traced to: 1) the entrenched power of the ruling sectarian elite, 2) the nature of the demands and the strategies of the protestors, 3) the role played by the army and the security forces, and 4) the role of external players.
Design and Analysis of Buffer-Aided Cooperative Networks using Deterministic and Reinforcement Learning Techniques. (c2022)
Authors:   ,   Lebanese American University, El Zahr Sawsan
Published: August 2022

Applications enabled by 5G technology resulted in an unforeseen increase in data traffic and data flows from any source to a destination are experiencing increased outages, delays, and drop-outs. Cooperative communication is one way to cope with this problem by integrating relays into systems to help a given source to communicate with its destination efficiently. Relays enable multiple shorter paths of better quality and equipping relays with buffers will further increase the degrees of freedom and allow for the mitigation of the fading effect. On the other hand, these benefits come at the expense of added complexity to the system. The problem of relay selection is a challenging task that can account for multiple parameters such as: the channel state information, the buffer states, and the position of relays. In this thesis, we address this problem in two ways: deterministic and learning-based techniques. Multi-hop systems with buffer-aided half-duplex relays are considered. First, we propose a new relaying strategy that is dynamic and can achieve multiple levels of trade-off between the average packet delay and the outage probability. The system is analyzed in a Markov Chain framework and all theoretical results are checked for accuracy with simulation curves. Asymptotic analysis is the key approach to derive closed-form expressions solely dependent on adjustable parameters of the system. We could prove the superiority of this scheme compared with other benchmark schemes from the literature. Then, further relaying strategies are devised and compared. Additional performance levels are achieved to fit in different applications requirements. Next, for more complex setups, deterministic analysis becomes cumbersome, thus reinforcement learning techniques are used to efficiently boost the performance. A deep RL agent is trained with a joint reward until it converges to an optimum performance. We demonstrate the efficiency of this approach to further increase the throughput of cooperative systems under different interference and design constraints.
The post COVID-19 implementation of the flipped classroom model in Lebanon in an English Language spelling unit for fourth graders. (c2022)
Authors:   ,   Lebanese American University, Ghozayel Souhair
Published: August 2022

The flipped classroom approach or model is a blended method of teaching that has gained a lot of popularity lately. The idea of the flipped classroom approach is old, but its application is fairly new. The aim of this paper is to test the effect of the implementation of the flipped classroom model in Lebanon post the COVID -19 period on fourth graders’ motivation level and academic achievement in comparison with the traditional approach. A quasi-experimental mixed method approach was conducted once a week over a whole semester in a private school in the city of Beirut. A grade four class was sampled, and 12 students participated in the study. In order to ensure the validity and reliability of the study, triangulation was used in data collection and analysis. Questionnaires, pre and posttests, interviews, and reflections were used for data collection. the research questions. The interviews were compiled, transcribed, and interpreted. The compiled results showed some considerable differences confirming the hypothesis proposed that the implementation of the flipped classroom model in fourth grade after the COVID-19 lockdown in Lebanon is not as effective on students’ motivational and academic achievement levels as the traditional classroom would be. It is recommended that future research studies the effect of this approach on students in upper elementary grades and once the COVID situation settles down.
Lebanese Teachers’ Perceptions of their Subjective Well-being in Times of Crisis. (c2022)
Authors:   ,   Lebanese American University, Atchan Tala
Published: August 2022

Lebanese citizens in general and school teachers in particular have been experiencing intensely challenging circumstances since October 2019, including a political upheaval, an economic collapse, a global pandemic and one of the largest non-nuclear blasts in recorded history, thus jeopardizing their lives and their livelihood. This study examines how English K-6 teachers at private schools in Beirut describe their mental well-being in light of the health, economic and political unrest following the Beirut port explosion. The study utilizes a mixed method research design triangulating data from a quantitative survey, semi-structured interviews, and auto-ethnographic journals to gain insight into the perspectives of the teachers regarding their subjective wellbeing. The quantitative results show that the teachers’ wellbeing has been greatly impacted by the explosion and the concurrent crises, where the majority of the teachers reported not getting the needed support to persevere and manage during these tough times. The majority of the teachers also reported high levels of stress and felt that they were unsafe in the country, where more than half of the participants expressed an intent to leave Lebanon. The qualitative data supports findings from the quantitative data, where the thematic analysis gave rise to themes that illustrate the traumatic experiences of the teachers during this period of protracted social crisis. Participants profoundly expressed their struggle with their psychological health post blast, as well as highlighted the need for support. Hence, prioritizing teachers’ wellbeing is key to their perseverance as Lebanese citizens and as educators who play a central role in maintaining flailing educational system in Lebanon.

History of Science in a Harmonic Style [Review: Smagina G.I. “Learning Science Historically…”: Russian History of Science in the Early Decades of the 20th Century. St. Petersburg, Rostok, 2020. (In Russian)]
Authors:   Dostoevsky Omsk State University, Omsk, 644077 Russia, Korzun V.P.
Published: August 2022

This review discusses the structure and key points of G.I. Smagina’s book devoted to the institutional and content development of the Russian history of science as a discipline during the early decades of the 20th century. The major focus falls on the process of institutionalization of the history of science in Russia that took more than 15 years – starting from the establishment of the Commission for the Publication of the Collection of Articles “Russian Science” in December 1916 until the foundation of the Institute of Science and Technology of the USSR Academy of Sciences in February 1932. The monograph consists of five chapters and appendices, which make up almost a third of the entire work. The genre of the reviewed book is defined as a documentary monograph. The institutional and anthropological aspects of the study are emphasized. The researchers who were involved in the shaping of a new discipline are identified. The author believes that over 400 people participated, in one way or another, in the studies within the scope of the history of science. Brief intellectual biographies of both the leaders of the two commissions (A.S. Lappo-Danilevsky, V.I. Vernadsky, N.I. Bukharin) and ordinary participants/creators of the historical and scientific process are presented. Plots related to the practices of popularization of science within the framework of academic structures are distinguished as innovative issues. Based on G.I. Smagina’s reasoning, two levels of popularization are singled out: within the corporation and outside it (in the space of mass culture). A hypothesis about the change in the conceptual settings during the development of the history of science as a discipline in the first third of the 20th century – from a humanitarian interpretation of the history of science to a socially oriented concept – with the subsequent institutionalization of the process is introduced.
On the Correspondence between I.M. Grevs and S.I. Arkhangelsky (1920s): The Aspects of Personal Biography and Historiography

Published: August 2022

This article considers an important source on the evolution of Russian historical science. These are four letters written in 1926–1928 by the leading historian I.M. Grevs (1860–1941) to his colleague S.I. Archangelsky (1882–1958), a future corresponding member of the Academy of Sciences of the USSR. Unfortunately, the response letters of S.I. Arkhangelsky have been lost. The letters under study focus on two main problems. I.M. Grevs unsuccessfully helped S.I. Arkhangelsky to publish the historical source he had translated – “The Edict on Maximum Prices” of Emperor Diocletian. In this connection, the problems of scientific formation and ideas of S.I. Arkhangelsky, the difficulties faced by the USSR historians of the 1920s who wanted to publish their scientific works, and the scholarly activity of I.M. Grevs in the Soviet period are considered. S.I. Arkhangelsky and I.M. Grevs adhered to different directions in interpreting world economic history – Eduard Meyer and Karl Bücher, respectively. S.I. Arkhangelsky refused to criticize I.M. Grevs, the reasons for which are discussed here. Another chief point of interest in the letters is the problems of local history studies. Based on the analysis of the exchange of views, new interpretations of the facts of I.M. Grevs’s biography – his travels along the Volga River, meetings with the figures of the Nizhny Novgorod Scientific Society for the Study of Local History – are offered. These and other issues are presented in the biographical context of communication ties between both the historians. The article is accompanied by the full texts of the letters and commentaries
What are Historians for? Notes on the Possibilities and Limits of Disciplinary History
Authors:   Institute of World History, Russian Academy of Sciences, Moscow, 119334 Russia, Chekantseva Z.A.
Published: August 2022

The image of history that emerged during the age of modernity has become a problem both in intellectual culture and in the everyday life of the 21st century. Our turbulent world and numerous texts convince us that history is no longer what it used to be. Nevertheless, historians work primarily within the settings of normative history, which foundations were shaped in the 19th century. Researchers have long discussed the changes taking place. However, along with a critique of the established protocols of historical research in line with the reflexive turn in knowledge (“epistemological and historiographical at a time” as François Hartog argues), another historical optic and a new ethos of history are now being sought and formed in the transdisciplinary space. In this theoretical discourse, the understanding of disciplinary history and its future relates to the state of knowledge in a broad sense. The article discusses several aspects of this vast topic based on the texts of historians, philosophers, sociologists, and anthropologists: the status of history in the contemporary world and its relationship with the past; temporal issues of historical culture; and the new ethos of history and the historian’s identity. Among the numerous challenges faced by humanity at the dawn of the third millennium, the following two stand out: transdisciplinarity and the Anthropocene.

Authors:   Korean Institute of Smart Media, Bang Junseong , Ahn Sunghee
Published: August 2022

Metaverse provides a simulated environment where a large number of users can participate in various activities. In order for Metaverse to be sustainable, it is necessary to study ethics that can be applied to a Metaverse service platform. In this paper, Metaverse ethics and the rules for applying to the platform are explored. And, in order to judge the ethicality of avatar actions in social Metaverse, the identity, interaction, and relationship of an avatar are investigated. Then, an action-based audit approach to avatar interactions (e.g., dialogues, gestures, facial expressions) is introduced in two cases that an avatar enters a digital world and that an avatar requests the auditing to subjects, e.g., avatars controlled by human users, artificial intelligence (AI) avatars (e.g., as conversational bots), and virtual objects. Pseudocodes for performing the two cases in a system are presented and they are examined based on the description of the avatars' actions.

Published: August 2022

THE PURPOSE. Development and implementation of a set of theoretical and practical recommendations for creating scientifically founded heat flow diagrams for pulp and paper processes, intensifying heat exchanging processes under the economical use of energy resources. METHODS. The method of thermodynamic analysis on the basis of exergy increments in the process of interaction of heat flows is proposed, it allows evaluating the energy efficiency of both individual PPI units and the entire process flow; mathematical relationship between exergy efficiency of process elements and that of a complex heat flow diagram; schematic diagram of a heat recuperator of PBM drying section with a closed loop for the air delivered to drying. RESULTS. Thermodynamic analysis was made to evaluate energy efficiency of PPI equipment; the relationship between conversion factor of thermal pumping plant and thermodynamic properties of actuating media was obtained. Sulfate pulp production was considered in detail. The low energy efficiency of the existing process flow diagram is shown, with its exergy efficiency being equal to 48%. A main share of the consumed exergy (71% of the incoming one) relates to the recovery boiler processes. The process flow diagram consisting of hydrochemical pulpchips processing is suggested. The recovery boiler and rotary-type lime kiln are removed from that flow diagram. Risks of air and water basins pollution fall. The main ways for increasing energy efficiency of lignosulfonates production at sulfite pulp plants are mentioned. DISCUSSION. Further development of energy efficient pulp technologies can be forecasted on the basis of application of fluid technologies such as supercritical water oxidation (SCWO). The positive results of research in water chemistry under supercritical parameters give promise to predict success in developing the energy efficient pulp technology by exposing pulpchips to water at the subcritical and supercritical parameters. Paper and board production relates to the complex physical–chemical and heat-wet processes. The thermodynamic studies allowed determining low exergy efficiency of a drying section of paper and board machine that is because of inefficient operation of the heat recuperation unit. This circumstance is responsible for the bulk supply of low pressure steam from a heat and power plant. The main ways for improving the heat flow diagram of PBM drying section are shown. Cogeneration issues in the pulp and paper industry are considered. The essential attention is given to environmental safety of energy efficient technologies. CONCLUSION. The paper presents main ways for increasing energy efficiency of basic production processes at pulp and paper enterprises. Based on the analysis of exergy efficiency of individual equipment elements and the entire process flow diagrams bottlenecks were revealed and measures for their removal were suggested.

Authors: Bryakin I. V. , Bochkarev I. V.
Published: August 2022

PURPOSE. To develop a differential parametric inductive transducer of vibration values into an electrical signal, which is a vibration displacement sensor (DV) with a new principle of operation. Theoretically substantiate the performance of the proposed DV. To develop a new system for vibroacoustic monitoring of the technical condition of overhead power transmission line (TL) supports using the proposed DV. METHODS. When solving this goal, the theory of parametric transducers and the main provisions of the theory of vibration diagnostics were used. RESULTS. The design feature of the developed DV is the absence of an excitation coil, and its functional elements form a full-fledged measuring bridge, the arms of which include interturn capacitances of the windings of the first and second measuring coils, as well as capacitances formed by a metal cylindrical electrode with a coaxially located inside it ferromagnetic rod and the first lower rows of wire windings of the measuring coils. The bridge circuit operates in a resonant mode, which ensures the high sensitivity of the proposed sensor, and the quadrature conversion of the information signal provides the necessary level of noise immunity. The received signal is a functional dependence of the output voltage of the measuring bridge on the magnitude of external vibrations, the characteristics of the temporary realizations of which reflect the degradation processes occurring in the power transmission line supports. CONCLUSION. The proposed system for monitoring the integrity of power transmission line supports is actually a distributed real-time sensor network that implements PLC technology. The DV of each sensor module registers microvibrations of the structural elements of the corresponding power transmission line support, caused by natural disturbing factors during their operation, and converts them into an electrical information signal, which forms the basis of monitoring information about the current state of the power transmission line support structural elements.

The average duration of the service period (SP) was 130 days, and the lactation period (LP) was 334 days in the cows of the State Enterprise "Chaika" of the UBWD breed for the third lactation. Milk yield was equal to 8334 kg with a fat content of 3.78%, and daily yield of milk was 24 kg. The best were cows that were impregnated with heifers at the age of 12–18 months.

For three lactations, the average duration of SP was 154 days and LP was 361 days, and the milk yield was 9315 kg with a fat content of 3.78%. The daily yield of milk was at the level of 25.7 kg. Younger cows had the best performance.

In the cows of CJSC "Agro-Region" of the third lactation (142 cows), the post-calving recovery period (RP) lasted an average of 78 days, the service period – 114 days. and lactation – 328 days. with a yield of 7.558 kg, the fat content of milk was 3.77%, and the daily yield was 23.1 kg.

The best economic indicators were cows of the Holstein and UBWD breeds. For three lactations in 508 considered cows, the average duration of RP was 74 days, SP – 120 days and LP – 338 days. The yield of milk was at the level of 7.823 kg with a fat content of 3.75%, and the daily yield was 23.5 kg. The best indicators for the third lactation and for three lactations were cows of the Holstein and UBWD breeds.

Experiments proved the economic feasibility of inseminating heifers at the age of 14–18 months, and well-developed heifers at 12–13 months, which positively affects the reproductive capacity and milk productivity of cows.

Published: August 2022

Antibody drug conjugates (ADCs) are rapidly becoming a cornerstone in targeted therapies, especially for the treatment of cancer. Currently, there are 12 FDA-approved ADCs, eight of which have been approved within the last five years, with numerous candidates in clinical trials. The promising clinical perspective of ADCs has led to the development of not only novel conjugation techniques, but also antibody formats, linkers, and payloads. While the majority of currently approved ADCs relies on cytotoxic small molecule warheads, alternative modes of action imparted by novel payloads and non-classical antibody formats are gaining attention. In this review, we summarize the current state of the art of ADC technologies, as well as comprehensively examine alternative payloads, such as toxic proteins, cytokines, PROTACs and oligonucleotides, and highlight the potential of multi-specific antibody formats for the next generation of therapeutic antibody conjugates.
How creative personalities look like and whether scientists and artists have different creative personalities? Revisiting meta-analyses

Published: August 2022

Previous studies have shown that, among the Big Five personality traits, Openness (O) and Extraversion (E) are the best predictors of creativity. The present study, however, goes beyond the specific Big Five traits, by testing the association between creativity and the General Factor of Personality (GFP) - a presumed broadest construct in personality hierarchy, as well as two intermediate higher-order factors - Stability and Plasticity. Using the findings from previous meta-analyses we provided robust tests of how the higher-order personality factors relate to creativity (Study 1) and Creative Self-believes (CSBs; Study 2). Study 3 tested whether the GFP and two intermediate factors could differentiate three contrast groups: (1) scientists VS non-scientists; (2) creative-VS less creative scientists; and (3) artists and non-artists. Using Structural Equation modeling, we found that a hierarchical-GFP model fits the data better than an uncorrelated Big Two model. In the hierarchical model, the GFP showed relevant correlations with creativity (ρ =.22; N = 56748; Study 1) and a CSBs (ρ = .50; N = 19861; Study 2). In Study 3 we found the GFP could be used to differentiate scientists from non-scientists (d = .17; N =4852) and creative scientists from less creative scientists (d = .24; N = 3918). As the literature suggests that the GFP reflects social effectiveness we argued that the GFP is a useful predictor of creativity in personality because it relates to the innovative/original as well as socially useful/adaptive characters of creativity.
When Bigger is Better: Size of Strategy Repertoire Predicts Goal Attainment

People are highly motivated to change their behavior. Unfortunately, many people have difficulty doing so. Building on recent theorizing, we propose that having access to a wide range of strategies – that is, a larger strategy repertoire – can help people achieve their goals. In eight samples across a variety of domains, participants (Ntotal=2,347) reported their use of seven strategies that determined their strategy repertoire for a particular goal. Findings indicated that having a larger strategy repertoire predicted goal attainment. These findings replicated across domains (healthy eating, academic performance, saving money), among self-set personal goals, at both the between-person and within-person levels, and were robust to different operationalizations of strategy repertoire, but differed by behavior. Specifically, having a larger strategy repertoire consistently predicted subjective goal progress, healthier eating, and more adaptive financial behaviors, but not snack intake or subjective credit score. Among the people who reported on multiple goals, we also found that their strategy repertoire was highly similar across domains. Together, these findings highlight that having a larger strategy “toolbox” has important implications for downstream regulation processes, which sets the stage for lasting behavior change.
Global mobility of the recent STEM postdoctoral workforce registered in ORCID
Authors: Kim Hyunuk
Published: August 2022

Postdoctoral researchers contribute to scientific, technological, and societal innovations under the supervision of academic faculty and domain experts. Their international movements facilitate the advancement and diffusion of knowledge and thus are important for research and development. To understand postdoctoral mobility at a global scale, this paper analyzes self-reported career trajectories of postdoctoral researchers by leveraging Open Researcher and Contributor ID (ORCID), focusing on five STEM fields: Biological Sciences, Biomedical and Clinical Sciences, Chemical Sciences, Engineering, and Physical Sciences. The U.S. and European countries are major destinations for the first postdoctoral position across the selected fields, and three Asian countries – China, Japan, and the Republic of Korea – also attract postdoctoral researchers in Chemical Sciences and Engineering. Gender differences are observed for some specific cases mainly due to the tendency that female postdoctoral researchers are more likely to stay in a single country or less likely to move to the U.S. for the second postdoctoral position compared to male postdoctoral researchers. The results would be leveraged to design science and technology policies for postdoctoral researchers in consideration of additional factors, such as culture and language.

The words entrepreneur, entrepreneurs and entrepreneurship acquired special significance in the context of economic growth in a rapidly changing socio-economic and socio-cultural climate. In the present study, an attempt has been made to evaluate the role of GIDC in entrepreneurship development with special reference to 200 chemical units of Ahmedabad, Nandesari, Ankleshwar, Sachin and Vapi Industrial Estate of Gujarat State. Entrepreneurship is one of the important segments of economic growth. GIDC provides different types of facilities. But the satisfaction of entrepreneurs regarding facilities provided by GIDC is varying for entrepreneur to entrepreneur, facility to facility and estate to estate. This paper concluded that the infrastructural facilities like internal road, water supply, drainage, post office, bank, insurance, hotel, government notified area office and hospital are satisfied but land and building, school and warehouse are not satisfied. GIDC does not play proper role regarding grievance handling. In short, almost all the value-added services are not fully satisfied.
