Authors: Loppies Cindy Regina Magdalena , Soukotta Dwight , Setha Beni , Tentua Eirene
Published: June 2022

Fishery products are a high source of nutrients, especially fatty acids. The smoking technology with liquid smoke is being developed to preserve fishery products. With this processing, fish are expected to be more durable and have better nutritional content, especially polyunsaturated fatty acids (PUFA), needed in the body. For this reason, research has been carried out to see the impact of fish processing with liquid smoke technology on the fatty acid profile of smoked Indian scad. The method used is the experimental method using coconut shell liquid smoke and samples of fresh and smoked Indian scad. The results showed that the fatty acid profile of fresh and smoked Indian scad contained 27 types of fatty acids consisting of 11 saturated fatty acids and 16 unsaturated fatty acids. The content of polyunsaturated fatty acids (PUFA) in fresh and smoked Indian scad is greater than the content of saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA). The high ratio of PUFA-ω3/PUFA-ω6 and the low value of Index of Atherogenic (IA) and Index of Thrombogenic (IT) of fresh and smoked Indian scad treated with coconut shell liquid smoke indicate the quality of fish fat is very good for consumption which is beneficial for health.

Daya simpan buah tomat yang dilapisi kitosan kepiting dan udang sampai dengan konsentrasi 6% dapat diperpanjang 16 hari.
El ch´ak ab´al. Del baldío a la actualidad
Authors:   UNACH, Gómez Hernández Antonio
Published: June 2022

Ch´a ab´al vocablos del tojol ab´al, literalmente, ch´ak equivale a “terminar, acabar, agotar”, “dar algo por concluido”; en tanto que ab´al es “la palabra dicha”. Así, podrían traducirse como “finalizar la palabra”, “el fin de la palabra dicha”, la “conclusión del acuerdo”. Pero ¿el fin o la conclusión de qué? Si bien es cierto que ch´ak ab´al se emplea para otros compromisos, ha sido y es en la actualidad el concepto que marca la formalización de una pareja para cohabitar como marido y mujer, palabras que dan socialmente la categoría de casado o casada a las personas; sin importar las formas y tipos de vías preferidas para hacerse de pareja. Si es eclesiástico, civil, fuga concertada con o sin noviazgo previo, la negociación final de las familias implicadas (entrega de la joven o solicitud del perdón) es llamada ch´ak ab´al, momento que marca el final de la etapa para dar paso a la categoría de persona completa, persona adulta.
Envejecer en Chiapas. Etnogerontología zoque
Authors:   UNACH, Reyes Gómez Laureano
Published: June 2022

En este estudio en la perspectiva de la antropología médica se recorre, primero, el registro etnográfico de una vejez idílica (masculina) y homogénea que, hipotéticamente, viven los viejos indígenas, otorgándoles un poder prácticamente gerontocrático. Posteriormente, se contrasta la información in situ con la teórica, y se construye un modelo explicativo de la cultura zoque de la vejez en donde se hace énfasis en cómo los zoques conciben culturalmente la gradación de la edad, el rol social, distinguiendo entre vejez masculina y femenina, los estigmas y virtudes, y el perfil epidemiológico, entre otros muchos tópicos. Posteriormente, se discute que la vejez se afronta en una forma diferencial, según la combinación de factores como las condiciones de salud, la economía, las redes sociales y del individuo, las afectivas, viudez, soledad, estatus social, etcétera, que dan marco para vivir una vejez muy heterogénea, especialmente cuando la población de “viejos” (de 60 o más años de edad, criterio estrictamente demográfico) se incrementa considerablemente, como en el caso de los zoques, que se han sextuplicado en los últimos 60 años. Esta obra expone la nueva forma de concebir y vivir la vejez, en la que la autoridad y los conocimientos “tradicionales” son cuestionados ante la nueva realidad sociocultural. Jóvenes y adultos más instruidos, mejores bilingües, y con mayores relaciones con el exterior, arrebatan el poder económico y civil de los viejos, con saldo a favor de jóvenes y adultos maduros, marginando a la población anciana, y con estatus social no necesariamente de prestigio.

This study endeavours to determine whether, and to what extent, adapted methods, external circumstances, and subjective factors impacted teachers’ performance in the online teach- ing of foreign languages for professional purposes at the tertiary level, as evaluated by the teachers themselves. a survey was carried out via an online questionnaire in December 2020 and in January 2021; the sample consisted of 60 respondents from 13 towns in Croatia. The study explored (i) the impact of adapted teaching methods in online teaching on teachers’ performance; (ii) the impact of external factors on teachers’ performance (external factors defined as those which teachers could not directly influence, such as the number of classes, the size of groups, online platforms, academic misconduct among students, working condi- tions, the support of higher education institutions); (iii) the factors of teacher dissatisfaction with teaching online. The results of the study reveal that the teachers who managed to adapt their teaching methods to the online medium are more satisfied with their performance, and so are their students. Furthermore, the adverse external factors, as well as subjective factors of dissatisfaction, did not substantially impact the performance of online teaching. The study contributes to the debate on the teaching of foreign languages for professional purposes at the tertiary level and offers practical implications for preparing and organising online classes, selecting teaching materials, and assessing and evaluating students. Finally, the study pro- vides recommendations for further research on online foreign-language teaching in higher education.
Explicit and implicit knowledge of English tenses of primary school EFL learners in Bosnia and Herzegovina
Authors:   International Burch Unviersity, Sarajevo, Bosnia and Herzegovina, Dubravac Vildana
Published: June 2022

The linguistic knowledge of foreign language learners appears to be partly implicit and partly explicit. Learners rely on implicit knowledge when involved in spontaneous everyday com- munication, while explicit knowledge enables them to reflect on language structures and reco- gnise or use metalanguage. The present study investigated the explicit and implicit foreign language learners’ knowledge of English tenses in the Bosnian context at the end of the first educational cycle, i.e., primary school, by means of a metalinguistic test, an untimed gram- maticality judgement test and an elicited imitation test. The study aimed at exploring the var- iability in the quantity and quality of EFL learners’ knowledge and the relationship between different types of knowledge based on three factors, namely gender, average grade, and start- ing age. While revealing quite limited knowledge of the target structures, the findings showed no significant difference between explicit and implicit knowledge, while the correlation co- efficients between them were relatively high. Out of the three factors, a three-way ANOVA showed that only average grade proved to have a significant main effect on EFL knowledge. The interaction effect of gender and grade was significant on the participants’ overall EFL knowledge and their explicit knowledge, whereas a significant interaction effect of all three factors was confirmed only on explicit knowledge.

The aim of this paper is to take a closer look at the competences of foreign-language instruc- tors teaching English to preschool-aged children. More precisely, the goal was to investigate the professional and teaching competences of EFL instructors in the Osijek Kindergarten (Dječji vrtić Osijek) a city-wide institution consisting 26 preschools. The results shed light on the following issues: the different qualifications with which EFL instructors certify their professional competence, the extent to which the instructors are language models to the chil- dren, the extent to which the subject-specific organization of teaching is adapted to the young age of the children, and the use of teaching materials and aids. The results show that there are four different profiles of EFL instructors in the Osijek Kindergarten: preschool teachers, primary-school teachers with an integrated EFL program, bachelors of English language and literature, and EFL teachers with MAs in English language and literature. It was also esta- blished that the approach to teaching differed somewhat between preschool teachers and other profiles of EFL instructors – i.e., preschool teachers choose activities and materials that are more suitable to the abilities and personal interests of preschool-aged children.
Sustaining Canadian Studies in the U.K.: Role Play as an Engaging Pedagogical Tool to Teach Canada Abroad
Authors: Flanagan Luke
Published: June 2022

While scholars have been successfully offering courses in Canadian Studies abroad for more than three decades, the recent cancellation of the Government of Canada’s funding program, Understanding Canada, puts such foreign-based teaching programs in a state of flux. Given that there is now little financial support for institutions, courses and conferences, instructors must ensure that courses in Canadian Studies are engaging and accessible in order for the discipline to stay relevant within this new fiscal reality. One solution could be to use innovative teaching techniques to demonstrate the value of Canadian Studies as an academic discipline. My experience at the Centre of Canadian Studies (the Centre), University of Edinburgh provides a case study for the use of this approach. In a first-year undergraduate course at the Centre, offered in 2009-10, I used role play to teach the arguments for and against the establishment of Canada wherein each student took on the guise of a specific delegate at the 1864 Charlottetown Conference and argued the case in an open debate. This exercise simultaneously allowed me to deliver the necessary content while also providing students with the opportunity to immerse themselves in the core arguments and characters. As a result, barriers to learning were reduced as content became more accessible and the interdisciplinary nature of Canadian Studies became more evident because each student approached the exercise from their own subject specialism.
Improvement of a methodological approach to assessing the fire hazard of mattresses
Authors: Konstantinova N. I. , Zuban A. V. , Bulgakova A. A.
Published: June 2022

Introduction. Textile materials and products (upholstered furniture, curtains, bedding, decorative items, etc.) are among the most flammable materials in residential and public buildings. They largely affect the fire propagation speed and formation of dangerous fire factors in combustion. Therefore, the issues of improving the requirements governing their fire-safe use are particularly relevant.

Aims and purposes. Presently, the fire safety of furniture products is regulated by the Technical Regulations of the Customs Union 025/2012 «On safety of furniture products» in Russia. However, differences in testing procedures and evaluation criteria, demonstrated by the applicable standards, do not always allow objectively assessing the flammability of upholstered furniture products and predicting their behaviour in case of fire. There is also no method for assessing the flammability of mattresses, and the currently used testing method, set by GOST R 53294–2009 (p. 5) cannot ensure a correct assessment and, hence, it results are distorted. The purpose of this work is to conduct an analytical study on foreign regulatory frameworks for the fire-safe use of upholstered furniture elements in public and residential buildings, to make an experimental assessment of the flammability parameters of materials and upholstered furniture, as well as develop proposals for improving the methodological approach to the fire hazard assessment and the use of mattresses in public and residential buildings.

Results and discussion. The analytical studies have proven that fairly developed regulatory and methodological frameworks are in effect abroad. They ensure the fire-safe use of items of upholstered furniture on the premises of residential and public buildings and structures. Comparative experimental studies were conducted to assess the flammability of various composite combinations of mattresses and upholstered elements of furniture using GOST R 53294–2009 methods (p. 4 and 5), which identified large discrepancies between the test results due to the difference in the conditions of the thermal exposure in the course of testing.

Conclusions. It is necessary to develop and introduce a standard method of testing the flammability of mattresses into the domestic regulatory practice. It is advisable to set the requirements limiting the use of flammable elements of upholstered furniture in places of the mass presence of people to reduce fire propagation in case of ignition and formation of dangerous factors.
Role of the Baltic Republics in Soviet-French relations during the Non-recognition Period, 1919-1924
Authors: Magadeev Iskander E.
Published: June 2022

This article aims to define the role played by the Baltic Republics in the Soviet-French relations during the non-recognition period. The author tries to determine the place, which the Baltic Republics occupied in the French and Soviet conceptions of the “sanitary cordon,” to analyse the correlation between the ambitions and the capabilities of Paris and Moscow in Eastern Europe, to demonstrate the Soviet response to the interaction between the Baltic Republics and France. The article is based on the materials taken from the different French archives, as well as from the published French and Soviet diplomatic documents. The author emphasizes the ambiguity of the role played by the “Baltic factor” in the Soviet-French relations. The Baltic Republics (especially, Latvia and Estonia) were perceived by the French leadership as a part of the “sanitary cordon” aimed to separate Germany and the Soviet Russia from each other and to preclude their eventual “collusion” in the Eastern Europe. On the contrary, Moscow aimed to weaken the “sanitary cordon.” Paris didn’t exclude that the cooperation with future Russia performing the role of the counterbalance to Germany would be more important for France than full independence of the Baltic Republics. The Kremlin and the People's Commissariat for Foreign Affairs welcomed this point of view and tried to support those French political leaders that developed such an approach. The dynamics of the post-war international relations, as well as the priority given by the French government to the “German threat”, prompted Paris to recognize the USSR, which met the interests of Moscow. The considerations of the “big politics” were more important than the voices of the “small countries” which tried to influence the interaction between the more powerful actors.
Protest Sentiments of Estonian Students in 1967-1968: on the Documents of the Komsomol Central Committee
Authors: Kamaeva (Bureeva) Elena V.
Published: June 2022

The article examines the little-studied topic of the evolution of the protest sentiments of the Estonian students in the 1960s, which found expression in student processions in Tallinn and Tartu in October 1968. A wide range of archival documents allows tracing the origins and dynamics of this phenomenon, as well as the perception of these events by the Soviet party leadership and the Central Committee of the Komsomol. It is noted that the data from archival sources and contemporary works by Estonian authors contradict each other with regard to the measures (reaction) taken by the Soviet leadership. The Student days in Tallinn and Tartu, planned as days of student solidarity, turned into mass marches and riots of a national and anti-Soviet character. The article concludes that the active protest of the Estonian students was caused by a whole range of reasons, among which are clear nationalist trends that intensified in the 1960s, the active penetration of Western European culture and ideology through travel contacts, communication with relatives living abroad, and international youth festivals. It was Estonia that in the 1960s was visited by the largest number of foreign tourists. Estonian Student construction brigades traveled to Eastern European countries, mainly to Czechoslovakia. The stirring up of Estonian students was influenced by the mass unrest of European students, which foreign authors call the “phenomenon of 1968.” The students of European countries advocated lowering the voting age, actively sought participation in political processes, protested against the large financial expenditures of their governments aimed at an arms race to the detriment of other sectors of the economy. Similar ideas were voiced by Estonian students at Komsomol meetings and scientific conferences. They also wished to create their own student organizations, independent of the Komsomol and Soviet ideology.

Este artículo recoge los resultados de una investigación que propone comprender la relación entrelos colectivos sociales en los territorios y las manifestaciones de arte urbano, como agentesde construcción identitaria en Medellín, Colombia. La metodología implementada fue cualitativa,de corte fenomenológico, cuyo alcance fue descriptivo. Se realizó un análisis de contenidoa partir de las manifestaciones de arte urbano identificadas y su relación con la construcciónde identidad a partir de la convivencia estética. Se realizaron entrevistas semiestructuradas amiembros de diversos colectivos de arte urbano en el centro, occidente y sur de la ciudad, rastreadosa partir de la etnografía visual. Dichos territorios comprenden la Comuna 13, el CorredorVial del Tranvía de Ayacucho y la zona centro y sur como una unidad estética. A partir deello, se propuso una reconstrucción histórica del arte urbano en Medellín y el análisis comparativode dos tipos de intervención artística en la ciudad: la que surge de las organizaciones socialeslocales e independientes, y la que se implementa desde la institucionalidad. Como resultado,se encontró que el arte urbano de la ciudad cuenta sus orígenes en las dinámicas socioculturalesindependientes, que serían institucionalizadas posteriormente, dinamizando transformacioneshistóricas, sociales, estéticas y económicas, en los entornos intervenidos. De este proceso surgenidentidades colectivas que se derivan de habitar el espacio estético, urbano y público, sea comohabitante y/o como protagonista de la intervención artística.

The purpose of this research is to determine the authority of the Kerinci Regency Government in managing the tourism sector of Lake Kerinci and to find out whether the Kerinci Regency Government has prepared a master plan for tourism development. The formulation of the problem studied is about how the authority of the Kerinci Regency Government in managing the tourism sector of Lake Kerinci? and whether the development of the Master plan has been in accordance with tourism?. This research is empirical juridical, based on the results of the study it can be concluded that the tourism management carried out by the Kerinci Regency Government has not been running well. This is due to the lack of coordination between regional apparatus and the inconsistency from the government, as well as the lack of human resources according to the field of work, as well as the lack of coordination and cooperation as well as follow-up from the Jambi Provincial Government in tourism development and management. The Kerinci Regency Government already has a Tourism Master Plan and in tourism development it is also guided by the tourism master plan. However, in its implementation, several gaps were found in setting targets in the management of tourism development.

RIEMANNIAN GEOMETRIES OF VISUAL SPACE: VARIABLE CURVATURE AND HORIZON
Authors: Turski Jacek
Published: June 2022

Two dimensional (2D) images of light beams reflected off the objects in
space impinge on the retinal photoreceptors of our two laterally
separated eyes. Nevertheless, we experience our visual percept as a
single 3D entity—our visual world that we tend to identify with
physical world. However, experiments point to different geometries in
these two worlds. Using the binocular system with the asymmetric eyes
(AEs), this article studies the global geometric aspects of visual space
in the Riemannian geometry framework. The constant-depth curves in the
horizontal field of binocular fixations consist of families of arcs of
ellipses or hyperbolas depending on the AE parameters and the eyes’
fixation point. For a single set of AE’s parameters, there is a unique
symmetric fixation at the abathic distance such that the constant-depth
conics are straight frontal lines. Critically, the distribution of the
constant-depth lines is independent of such fixations. In these cases, a
two-parameter family of the Riemann metrics is proposed based on the
retinal topography and simulated constant-depth lines. The obtained
geodesics for a subset of metric parameters include the incomplete
geodesics that give finite distances to the horizon. The Gaussian
curvature of the phenomenal horizontal field is analyzed for all the
metric parameters. The sign of the curvature can be inferred from the
global behavior of the constant-depth ellipses and hyperbolas only when
for the metric parameters for which the constant-depth frontal lines at
the abathic distance fixations are geodesics.
Realization of the inverse scattering transform method for the Korteweg-de Vries equation
Authors: Grudsky Sergei , Kravchenko Vladislav , Torba Sergii
Published: June 2022

A method for practical realization of the inverse scattering transform
method for the Korteweg-de Vries equation is proposed. It is based on
analytical representations for Jost solutions and for integral kernels
of transformation operators obtained recently by the authors. The
representations have the form of functional series in which the first
coefficient plays a crucial role both in solving the direct scattering
and the inverse scattering problems. The direct scattering problem
reduces to computation of a number of the coefficients following a
simple recurrent integration procedure with a posterior calculation of
scattering data by well known formulas. The inverse scattering problem
reduces to a system of linear algebraic equations from which the first
component of the solution vector leads to the recovery of the potential.
We prove the applicability of the finite section method to the system of
linear algebraic equations and discuss numerical aspects of the proposed
method. Numerical examples are given, which reveal the accuracy and
speed of the method.
Adversity of industrial water pollution on agriculture and livelihood: Experiences of rural population of Dindigul
Authors: Kannan Srinivasan , Karuppaiah Rengasamy
Published: June 2022

Tannery pollution affected the water and livelihood of people in
Dindigul. Polluted water and soil reduced agricultural production;
contaminate drinking water, and livelihood. The present study aims to
study the adverse effects of industrial pollution on agriculture and
livelihood in Dindigul. Twenty randomly villages drew with an equal
number from the vicinity of tanneries and far. A survey was conducted
using a structured interview schedule among 400 men and women of 18
years and above from 20 villages. Details on Socio-Economic
characteristics, water, agriculture and livelihood were collected online
using the Kobo toolbox in the Tamil language. In affected and
non-affected villages 71 and 102 hold agricultural land only 53 and 87
have cultivated respectively. One third in affected villages and two
thirds in non-affected villages cultivated throughout the year.
Tanneries affected the livestock population, reduced agricultural
production, polluted irrigation, polluted soil and made it infertile,
and deteriorated the quality of agricultural produce. Compared to
economic benefits from tanneries the damage are exorbitant. Politicians
and policymakers ignored pollution and turned blind eye to the problems
caused to the rural population and livelihood.
Development of recommendation systems using game theoretic techniques
Authors: Sofikitis Evangelos , Makris Christos
Published: June 2022

In the present work, we inquire the use of game theoretic techniques for the development of recommender systems. Initially, the interaction of the two aspects of the systems, query reformulation and relevance estimation, is modelled as a cooperative game where the two players have a common utility, to supply optimal recommendations, which they try to maximize. Based on this modelling, three basic recommendation methods are developed, namely collaborative filtering, content based filtering and demographic filtering. The different methods are then combined to create hybrid systems. In the weighted combination, the use of game theoretic techniques is extended, as it is modelled as a cooperative game. Finally, the methods are combined with the use of a genetic algorithm where game theory is used for the parent selection process. Our work offers a baseline for the efficient combination of recommendation methods through game theory and in addition the novelty method, Choice by Game, for the parent selection process in genetic algorithms which offers consistent performance improvements.
Phenolic profile, antioxidant and antiproliferative activities of Convolvulus aucheri Choisy
Authors: Ozay Cennet , Mammadov Ramazan
Published: June 2022

Background/Aim. It is known that some members of the genus Convolvulus (C) L. are commonly used in Turkish folk medicine. These species are powerful in curing toothache and joint pains. Due to the limited information on the biological activities of C. aucheri, a species almost exclusively occurring in Turkey, we aimed to investigate the antioxidant and cytotoxic effects of three extracts obtained from the plant, as well as to characterize their phenolic profile. Methods. The anti-oxidant activity of the extracts was determined by using ABTS, NO, FRAP, phosphomolybdenum, and metal chelating assays. In addition, the bioactive compounds found in the extracts, such as total phenolics, flavonoids, and saponins, were determined. Cytotoxicity was assessed by using the CellTiter-Glo assay on HeLa and H1299 cancer cells. Results. The methanol extract of C. aucheri demonstrated the highest antioxidant activity as well as the highest phenolic, flavonoid, and saponin content. The high-performance liquid chromatography (HPLC) analysis showed that the major phenolic compounds in the extract were chlorogenic acid, (+)-catechin, rosmarinic acid, and rutin. The methanolic extract obtained from the aerial parts of C. aucheri was found to interfere with the viability of HeLa cells, with an IC50 value of 14.22 ?g/mL being recorded. Conclusion. Our results showed that C. aucheri could be a good candidate as a novel and alternative natural antioxidant and antitumor source.

Published: June 2022

Background/Aim. Hypervolemia is an important risk factor for the development of cardiovascular morbidity and mortality in patients treated with regular hemodialysis. There is still no reliable method for assessing the status of volemia in these patients. The aim of the study was to assess the status of volemia in patients treated with regular hemodialysis by measuring the parameters of the inferior vena cava (IVC) and bioimpedance. Methods. The effect of hemodialysis treatment on ultrasound parameters of the IVC, as well as on the parameters measured by bioimpedance, was examined before and after hemodialysis. The values of the N-terminal prohormone of brain natriuretic peptide (NT-proBNP) were measured both before and after hemodialysis. Forty-five patients were involved in this non-interventional cross-section study, including the patients treated with standard bicarbonate dialysis. According to the interdialytic yield, the patients were divided into three groups: I (up to 2,000 mL), II (2,000?3,000 mL), and III (over 3,000 mL). Results. The values of the IVC parameters and the parameters measured with bioimpedance were significantly lower after treatment with hemodialysis (p < 0.005). The third group of patients had a significantly higher total fluid volume in the body com-pared to the group I, as well as a significantly greater volume of extracellular fluid (p < 0.005). The significantly lower values of NT-proBNP in all groups (p < 0.005) were detected after hemodialysis. After treatment with hemodialysis, a positive correlation was observed between the concentration of NT-proBNP in the serum and the extracellular/intracellular water ratio. However, the correlation between NT-proBNP concentration and total fluid measured by bioimpedance spectroscopy did not reach statistical significance. Conclusion. Measurement of the IVC ultrasound parameters and volemia parameters using bioimpedance significantly contributes to the assessment of the status of volemia. Nevertheless, it cannot be used as a separate parameter, only in combination with all other methods.
CONUS Prepositioned Afloat Aircraft Carriers: A Concept for Mobilizing Heavy Brigades
Authors: HENDERSON CHARLES R. , BRADY STEPHAN P.
Published: June 2022

This research breaks from current prepositioning paradigms in order to answer the question: Could re-commissioned aircraft carriers prepositioned with heavy brigades in CONUS ports enhance the United States' ability to respond to global contingencies? The methodology used was an open-ended panel interview conducted during two site visits. The first was to the Puget Sound Naval Shipyard's Inactive Ships facility in Bremerton, Washington to inspect the decommissioned USS Constellation aircraft carrier. This panel primarily focused on the generation of size and cost data. The second visit was to Goose Creek, South Carolina for a panel interview with DynCorp contractors responsible for the exercise and care of afloat stocks. This panel focused on the ability of the ship's elevators and top deck to increase readiness by enabling the use of more rigorous land-based maintenance and exercising criteria. The study concludes that reactivation cost estimates are far below those previously espoused by similar research efforts. The use of the top deck and modified ship and maintenance regulations can enhance readiness of prepositioned stocks. Finally, the carrier's speed makes projection from CONUS ports a critical enabler for homeland defense in the global war on terror.
Comparison of Investment Preferences for International Logistics Zones in Kaohsiung, Hong Kong, and Shanghai Ports from a Taiwanese Manufacturer's Perspective
Authors: LU CHIN-SHAN , YANG CHING-CHIAO
Published: June 2022

This research empirically evaluates international logistics zones in Kaoshiung, Hong Kong, and Shanghai ports based on the importance of investment criteria from the perspective of investors in Taiwanese manufacturing firms. Results suggest respondents viewed political stability as the most important investment criterion, followed by corporate tax incentives, government administration efficiency, labor cost, and energy cost. Shanghai Port's industrial logistics zone has a very strong competitive edge in cost, market, and industrial related criteria. The international logistics zones in Hong Kong and Kaohsiung ports have advantages in infrastructure, political, and financial related investment criteria. Respondents preferred to invest in the international logistics zone in Shanghai Port rather than that in Kaohsiung or Hong Kong Ports. Leasing factory buildings to operate their business in an international logistics zone was the preferred entry mode. Theoretical and practical implications of the research findings are discussed.
A Disaggregate Analysis of Ocean Carriers' Transit Time Performance

Published: June 2022

This study provides a disaggregate analysis of ocean carrier speed and reliability. The findings produce direct evidence that dramatic differences in carrier transit time and transit time reliability, also referred to collectively as transit time performance, prevail across major trade lanes. These results bring attention to transit time performance, which previous studies have shown to receive little attention from shippers, especially for ocean carrier selection. Differences in transit time performance impact not only shippers' carrier selection decisions, but also their development of effective international ocean transportation strategies. Liner ocean carriers can also use these results as a benchmark to judge how well they perform relative to the competition.
Security and the Global Supply Chain
Authors: SARATHY RAVI
Published: June 2022

This article examines implications for global supply chains posed by security threats in the U.S. and elsewhere, and identifies actions for addressing those threats. The principal goal is to design security into the supply chain rather than seek to mitigate consequences after the fact. Redesigning supply chains to make them robust and resilient can help avoid and mitigate the impact of disruptions, whether from security breaches or other causes. Such efforts require collaborations with partners across the supply chains and with governments. The short-term costs of such security measures can be balanced against the long-term gains from improved supply chain performance and improved customer relations.

Authors: SHAO XIAOFENG , JI JIANHUA
Published: June 2022

Logistics reconfiguration is an active practice in the Chinese pharmaceutical industry. However, the reconfiguration performances are not satisfactory. This article investigates logistics reconfiguration strategies and develops a logistics reconfiguration success framework by a three-stage multi-method research approach. Telephone interviews and qualitative case study research methodology are used to collect data. From case studies, nine key success factors are identified. These factors are further validated as being relevant by a group of senior managers from industry. Finally, managerial implications are drawn.
Modeling Rail-Rail Exchange Operations: An Analysis of Conventional and New-Generation Terminals

Published: June 2022

Hub-and-spoke bundling networks in intermodal rail freight transport are suggested as a potential solution to help increase the intermodal rail market share. In Europe, three intermodal hub-and-spoke networks became operational in the 1990s. Trains are shunted or load units transshipped at the hubs in these networks. Shunting or transshipment is relatively time-consuming and cuts back on the advantages of hub-and-spoke networks. A new type of terminal, specifically designed for hubs in hub-and-spoke networks, has been suggested for introduction. At these terminals, standardized load units are transshipped efficiently from one train to another, instead of shunting rail wagons. Explorative evaluation studies give rise to the expectation that these new-generation terminals-under certain conditions-might perform more efficiently than conventional shunting yards and road-rail terminals. We still know very little about exchange operations at new-generation terminals and the differences from conventional road-rail terminals and shunting yards. The goal of our research is to obtain a thorough understanding of the operations and to compare performances of different exchange facilities. To reach this objective, dynamic simulation models were built in ARENA. The typical features of, and performance differences between, conventional road-rail terminals, shunting yards, and new-generation terminal operations are presented in this article.
Corporate Sustainability: A Model Uncertainty Analysis of Materiality
Authors: Berchicci Luca , King Andrew A.
Published: June 2022

For decades, scholars searched for a connection between a corporation's current performance with respect to sustainability and the future returns of its stock. In 2016, Khan, Serafeim, and Yoon published an apparent breakthrough in this quest: guidance on materiality from the Sustainability Accounting Standards Board allowed the construction of corporate sustainability scales that reliably predicted stock returns. Their finding had immediate and broad impact, but it remains, in its authors' own words, just “first evidence.” Here, we further explore the relationship between material-sustainability and stock returns by performing a “model uncertainty analysis.” We reproduce the original estimate but conclude that it is a statistical artifact. We then use machine learning to explore the practicality of employing historical associations to determine which aspects of sustainability are material to investors. We conclude that, for one popular source of data on corporate sustainability, accurate guidance on materiality may be difficult to achieve.

Cross Talk Between Insulin and Glucagon Receptor Signaling in the Hepatocyte
Authors: Habegger Kirk M.
Published: June 2022

While the consumption of external energy (i.e., feeding) is essential to life, this action induces a temporary disturbance of homeostasis in an animal. A primary example of this effect is found in the regulation of glycemia. In the fasted state, stored energy is released to maintain physiological glycemic levels. Liver glycogen is liberated to glucose, glycerol and (glucogenic) amino acids are used to build new glucose molecules (i.e., gluconeogenesis), and fatty acids are oxidized to fuel long-term energetic demands. This regulation is driven primarily by the counterregulatory hormones epinephrine, growth hormone, cortisol, and glucagon. Conversely, feeding induces a rapid influx of diverse nutrients, including glucose, that disrupt homeostasis. Consistently, a host of hormonal and neural systems under the coordination of insulin are engaged in the transition from fasting to prandial states to reduce this disruption. The ultimate action of these systems is to appropriately store the newly acquired energy and to return to the homeostatic norm. Thus, at first glance it is tempting to assume that glucagon is solely antagonistic regarding the anabolic effects of insulin. We have been intrigued by the role of glucagon in the prandial transition and have attempted to delineate its role as beneficial or inhibitory to glycemic control. The following review highlights this long-known yet poorly understood hormone.

Objective: To describe and compare patients with neck and back pain treated by physiotherapists in primary healthcare (PHC) and in departments for physical medicine and rehabilitation in specialist healthcare (SHC) in Norway.Design: Cross-sectional study using data from the FYSIOPRIM database in PHC and the Norwegian Neck and Back Registry in SHC. Neck and back pain patients in the period 2014–18 aged ≥ 18 years were included. Demographics, lifestyle and clinical factors were investigated.Results: A total of 8,125 patients were included: 584 in PHC and 7,541 in SHC. Mean age was 47.1 and 45.5 years, respectively, with more females in PHC (72% vs 56%). Low levels of education and physical activity, high workload and receiving social benefits were associated with treatment in SHC. Treatment in SHC was most common from 3 to 12 months’ pain duration. Higher pain intensity and lower health-related quality of life were found in patients treated in SHC, no differences were found for psychological distress.Conclusion: This is the first study comparing register data in patients with neck and back pain treated in PHC and SHC. Differences were found in pain and health-related quality of life, but levels of psychological distress were similar between patients treated in PHC and those treated in SHC.
