Challenges of a Multiple Super-long Span Suspension Bridge Crossing of the Irish Sea
Authors: Firth Ian , Walker Chris , Archer-Jones Cameron , Mountjoy Andrew
Published: August 2023

Constructing a 36km long bridge across the North Channel of the Irish Sea between Scotland and Northern Ireland in water up to 300m deep presents several substantial challenges. In March 2021, the authors were assigned the task of establishing whether such a crossing is feasible, as part of the UK Government's review of the connectivity between the four parts of the United Kingdom.

The technical challenges are enormous and focus principally on constructing the substructures and foundations in very deep water, the main cable design and erection, the severe environmental conditions and many operational factors. The solutions that emerged from the high-level study included a suspension bridge carrying twin railway tracks and dual three-lane carriageways on a multiple steel box girder deck structure, with seven spans of 3750m supported on eight pylons rising to a height of nearly 550m above sea level. Similar concepts have been developed by COWI previously for the Gibraltar Strait Crossing and the Yemen-Djibouti Crossing, and this study was able to draw on lessons learnt from that earlier work.

This paper describes the evolution of the preferred structural solution and focusses on the complex technical issues which set this project apart from any other long span bridge solution, including the deep water foundations and the design and construction of the main cables. It concludes with a discussion of the key risks and some lessons learnt for the design of such enormous structures in future.

Published: August 2023

The east span of the San Francisco-Oakland Bay Bridge (SFOBB) is a 3.6 km long structure that lies between two major faults, which can generate magnitude 7.5 M and 8.1 M earthquakes, respectively. Four distinct structures make up the bridge crossing, including the signature span of the bridge — the self-anchored suspension (SAS) bridge. With a length of 624 m and total deck width of 79 m accommodating 10 lanes of traffic plus a bike/ pedestrian path, it is named, in the Guinness Book of World Records, as the world’s longest self-anchored suspension bridge as well as the world’s widest bridge. The design life of the SFOBB is 150 years. Key considerations in design and construction include designing elements replacement after a major seismic event, proper fatigue detailing, and cable and anchorage zone dehumidification. This paper discusses the design and construction of this long span bridge to ensure optimal performance throughout its design life.
Data Quality for Structural Health Monitoring of Bridges
Authors: Makhoul Nisrine
Published: August 2023

The use of digitalization and reliance on relying on Structural Health Monitoring (SHM) in bridge engineering is increasing, especially for long-span bridges where the condition assessment becomes more challenging. Effectively, it ensures greater accuracy in damage identification and enhanced maintenance of existing bridges by collecting information on the bridge's actual condition (i.e., likely damage, its severity, etc.). This increased reliance on data and information raises the question of the quality of the data and its effect on the management strategy and the decision-making process for bridge engineering. To solve this issue, in this article, data quality indicators for SHM are first selected, then metrics for data quality are reviewed, and some metrics are proposed to assess them. Then, a bridge management strategy considering the data quality is suggested to improve bridge management and decision-making processes. This strategy considers several steps to account for the data quality of SHM in the life cycle assessment management, including mainly the value of information on SHM data quality and some life cycle system performance indicators, which now account for the SHM data quality.

Joint Iteration Method of unloaded Cable Shape and Pre-displacement of Main Cable Saddle for Long-span Suspension Bridges
Authors: Liu Chao , Gao Chun-song
Published: August 2023

In this paper, a new method for calculating the unloaded cable shape and main cable saddle pre-displacement in the construction of long-span suspension bridges is proposed, which is called the joint iterative method (JIM). In this method, the first iteration does not require presupposing the saddle pre-displacement, and the results of the unloaded cable shape obtained in each subsequent iteration cycle will be mined to guide the saddle pre-displacement correction in the next iteration. This method uses simplified cable models and convergence conditions different from classical methods. In the simplified model of main cable mechanics, equal horizontal component of suspension bridge on both sides of main tower is taken as implicit condition, and equal unstressed cable length of each span of main cable is taken as convergence condition in iteration. Using this method, the pre-displacement of the main saddle and the unloaded cable shape of the Yingwuzhou Yangtze River Bridge is calculated by MATLAB program and compared with its designed value. The results show that this method requires few iterations and has high speed and accuracy.

Published: August 2023

In the context of the Northern Marmara Motorway Section 8 Project, a new cable-stayed bridge, the Sazlidere Bridge, is being designed and works have already started on site. To support this fast-paced project, RWDI is collaborating with the design team and providing wind engineering services. The activities employ wind tunnel experiments and are focused on two main aspects: aerodynamic stability of the bridge and the risk of wind-induced overturning of large lorries crossing the bridge. With respect to aerodynamic stability, limited tests on a sectional model of the bridge deck were performed in one of RWDI’s wind tunnels using a state-of-the-art sectional model test rig. Testing of a full bridge aeroelastic model with relevant topography was also conducted allowing for the simulation of atmospheric turbulence from any wind direction. This testing was used primarily to verify the aerodynamic stability of the structure for various wind directions and to measure the buffeting response of the bridge to turbulent winds. Further wind tunnel testing on a small-scale rigid transport lorry model was completed to measure the aerodynamic force and moment coefficients of the vehicle as a function of wind direction. These data were combined with a numerical model for the roll-over stability of high-sided vehicles to calculate critical wind speeds versus wind direction for lorries driving along the central span of the bridge.

Introduction of Several New Bridge Construction Techniques
Authors: Xiao Xiangrong
Published: August 2023

This experience exchange article focuses on three new bridge construction techniques: Firstly, the section installation technique of the single-column steel leaning tower of the Fujian Qiyun Bridge. This process takes the self-elevating crane developed by CCCC as the technical core. It implements the lifting and alignment installation of the inclined variable-section steel tower segment. Secondly, the steel tower (including steel beam) and steel girder installation process of Shunxing Bridge in Foshan, Guangdong. In response to the nearly 300-ton hoisting load of the entire section of the steel tower, the builder abandoned the commonly used super-large tower crane and developed a self-climbing crane, which realized the installation of the 200m steel tower section and the steel beams of the upper, middle, and lower three-story tower body. At the same time, by replacing the functional kit, the tower segment hoist is transformed into a bridge deck crane, forming the function of installing the steel main girder. Thirdly, the installation process of the main arch rib and steel girder of Chongqing Liaozi Bridge. Facing the special environment such as ditches and mountains, the builder proposed and implemented the single arch rib vertical lifting, horizontal rotation, vertical placement and closure process, and completed the main arch rib installation. And they developed its own arch-load traveling crane to carry out the longitudinal transportation and erection of the steel girder. The common features of the new processes above are safer, faster, less labors and lower cost.
Technological Innovation of Multi-pylon Suspension Bridge
Authors: Wang Changjiang , Bai Yudong , Mei Hanyu
Published: August 2023

Multi-pylon suspension bridge is the bridge type scheme that bridge workers dream of. The rigid mid-pylon suspension bridge is the best solution for multi-pylon suspension bridges with more than three pylons. Its core is to improve the anti-slip performance of the cable saddle. Through a large number of experiments and induction, the nominal friction coefficient of the cable saddle considering the lateral wall friction resistance is obtained, and then a cable saddle is proposed with high friction performance. The calculation method of the nominal friction coefficient and the anti-slip evaluation method of the cable saddle are given. On this basis, combined with the improvement of wind resistance performance, driving comfort and multi-span branching capacity, a "live-load anchorage design method" for multi-pylon suspension bridges was proposed, and it was successfully applied on the engineering example-"Wenzhou Oujiang North Estuary Bridge" project.

Published: August 2023

Damping ratio is an important parameter for large span bridges. Bridges with low damping ratio are susceptible to abnormal vibration, therefore it is significant to monitor the damping ratio of bridges. This study investigates the variation of the damping ratio in the operating environment based on the monitoring data of a single-pylon cable-stayed bridge. The main span of the bridge is 225m.

The bridge is installed with a bridge health monitoring system to monitor the response and environment. An automatic damping ratio extraction method is developed to identify the damping ratios of the bridge. In addition, temperature and traffic monitoring data are analyzed and the effect on the damping ratio is investigated by correlation analysis. The results show that the damping ratio changes due to the operating environment. An increase in temperature leads to a slight decrease in the damping ratio. Traffic load also has an important effect on the damping ratio.

Braila bridge: Design and construction of the cable system
Authors: Idani Tatsuya , Shima Takanori
Published: August 2023

The Braila bridge is a three-span suspension bridge spanning the Danube in Romania with a main span of 1120 meters, currently under construction. This bridge will be the first constructed long-span suspension bridge in Romania. The construction of the main cable system started in March 2021 and completed in December 2021. Strands of the main cable are erected by using low tension aerial spinning method by which wires are spanned one by one on site and then bound into a strand. It is of importance to assure the quality of strand/main cable on site, and two methodologies were adopted. One is to control the deflection of the catwalk by water counterweight. With the progress of wire spinning, the catwalk deflects due to increase of the weight of the spun wires. The excessive deflection makes the variation of wire length within a strand which causes unbalanced stress distribution within the cable, and thus shall be avoided. The other is to move the tower top saddle during construction. Due to asymmetric superimposed dead loads between the spans, the tension force is not balanced between main span and side span during the main cable construction, and it may cause a slippage of strand at saddles which results failing of designated geometry. Therefore, the position of tower saddle was adjusted to have the equilibrium by hydraulic jacks. Thanks to the measures above, the quality of the main cable was assured on site, and the construction was completed on schedule.
Retrofitting of Severely Damaged Concrete Piers using Ultra-High Performance Concrete
Authors: Hogarth Kathryn , Ebrahimpour Arya , Mashal Mustafa
Published: August 2023

The use of Ultra-High Performance Concrete (UHPC) is gaining popularity for bridge applications in North America. UHPC has been used both in the construction of new and retrofitting of existing bridges. In this research, a novel use of UHPC as a concrete jacket for retrofitting of plastic hinge zones in cast-in-place and precast piers is proposed. Four large-scale cantilever pier specimens, two cast-in-place and two precast, are tested under cyclic quasi-static loading to drift ratios beyond Maximum Considered Earthquake (MCE). The piers are then retrofitted with UHPC jackets in their plastic hinge zones. The design philosophy for retrofitting is to shift the plastic hinge above the damaged region of a pier, thus re-instating capacity, stiffness, and ductility to the piers. Experimental results from testing of the piers along with guidelines on retrofitting and construction techniques are presented. It is shown that UHPC is indeed a competitive solution for retrofitting of concrete piers subjected to severe earthquake damage.

Authors: Takai Toshikazu , Yamamoto Shuhei , Harakawa Shinpei
Published: August 2023

The component of bolted connection is sometimes replaced due to some reasons, which are corrosion, bolt delayed fracture and so on. The influence or mechanical behaviour of bolt replacement of bolted connection applied tensile force was already investigated in previous studies. However, that of the connection applied the bending moment is not cleared. In this study, simple and small specimens of bolted connection were prepared and bolt replacement experiments under bending were conducted to clear the behaviour and compare it and that of bolted connection applied tensile force. And, numerical analysis was carried out to investigate the influence of bolt replacement focused on the order of bolt replacement. As a result, although the centre opening stretch of the upper side and the lower side was different due to bending, the averaged opening stretch was the same as that of the connection in tensile. The order of bolt replacement affected the opening stretch, however, did not affect the elongation of bolted connection.

Актуальність. Незважаючи на автоматизацію й комп’ютеризацію бойової техніки, зміни тактики ведення війни, фізична готовність залишається важливим і невід’ємним компонентом індивідуальної бойової готовності військовослужбовців, базою для всіх інших видів готовності. Чинна система фізичної підготовки неспроможна забезпечити фізичної готовності військовослужбовців до бойової діяльності й тому потребує докорінного реформування. Мета роботи – проаналізувати структуру управління системою ФП ЗС України з позицій системного підходу та обґрунтувати можливі шляхи її реформування. Методи дослідження – аналіз і синтез наукових праць та керівних документів із проблематики, що досліджувалася. Результати. Розкрито структуру управління системою фізичної підготовки, проведено її аналіз із позицій системного підходу. Визначено, що основною проблемою управління є те, що воно здійснюються двома керівними органами різного підпорядкування, які не мають спільних цілей, між котрими відсутні взаємопов’язаність і взаємодія, оскільки вони є елементами різних, несумісних між собою систем, кожна зі своїм специфічним середовищем: для одного – бойова підготовка військ, для іншого – спорт вищих досягнень. Висновки. Чинна структура управління фізичною підготовкою Збройних сил України суперечить методології конструювання соціальних систем і неспроможна забезпечити її ефективне функціонування. Запропоновано шляхи модернізації системи управління фізичною підготовкою Збройних сил України.

Мета роботи – виявити перспективність використання ефективних для силових видів спорту основних видів моделей тренувальних занять для підвищення рівня спеціальної ударної підготовки спортсменів із хор- тингу. Методи. Контингент обстежених складався із 60 спортсменів. Для кожної з трьох створених груп запропоновано окрему модель занять. Відмінність між моделями тренувань полягала у використанні різного варіанта поєднання вправ на тренажерах чи з вільною вагою обтяжень. При цьому використовувалася різна послідовність виконання базових й ізолюючих вправ. Контроль за змінами показників ударної підготовки (кількість влучно виконаних ударів ногами за 15 с із максимальною силою) відбувався на початку дослідження та протягом наступних трьох місяців із періодичністю в 30 днів. Результати. Установлено, що за три місяці досліджень найбільше підвищення рівня ударної підготовки на 28,8 % виявлено під час контрольної вправи

«кількість влучних прямих ударів коліном задньої ноги з однобічної бойової з максимальною силою за 15 с» у спортсменів другої групи. Відсутність кількісних змін досліджуваних показників простежено лише в спорт- сменів першої групи під час виконання таких вправ, як удар ногою знизу підйомом ступні в голову, короткий задній удар ногою. У спортсменів третьої групи, які використовували комбіновану модель тренувань, у порів- нянні з представниками інших груп, досліджувані показники підвищились у середньому на 11,2 % у зіставленні з вихідними даними. Висновки. Модель силової спрямованості, в основі якої використовуються комплекси вправ зі штангою та гантелями в умовах анаеробно-алактатного режиму енергозабезпечення та навантаженнями 85 % від 1RМ, згідно з результатами проведеного дослідження, є найбільш ефективною.

Published: August 2023

Актуальність. Одним з актуальних напрямів сучасних наукових досліджень у сфері фізичного виховання є вивчення всього спектра питань, пов’язаних зі здоров’ям, його формуванням та збереженням. Комп’ютеризація праці офісних працівників досягла високої концентрації – фактична 100 %. Офісному працівникові доводиться переробляти великі потоки різноманітної інформації, мати справу з постійною нервовою напругою, відчувати стрес. Учені почали звертати дедалі більшу увагу на наслідки, із якими стикаються користувачі персональних комп’ютерів. Мета дослідження – аналіз показників фізичної підготовленості жінок 36–44 ро- ків, які працюють в офісі. У науковому дослідженні взяли участь 49 жінок другого періоду зрілого віку, серед них 36–39 (n = 28) і 40–44 років (n = 21). У досліджені застосовано такі методи дослідження: теоретичні, педагогічні, математичні. Результати дослідження. У процесі дослідження нами було виконано оцінку фізич- ної підготовленості жінок 36–44 років. Першим етапом статистичної обробки отриманих показників фізичної підготовленості жінок 36–44 років є їх перевірка на відповідність закону нормального розподілу за критеріями узгодженості. Усі показники фізичної підготовленості жінок 36–44 років, за винятком «піднімання тулуба в сід, разів» жінок 36–39 років, не відповідали закону нормального розподілу. Отже, подальшу статистичну обробку результатів тестування фізичної підготовленості жінок 36–44 років проводили з використанням непараметрич- них методів. Висновки. Результати дослідження рівня фізичної підготовленості (тести нахилу тулуба вперед із положення сидячи; піднімання тулуба в сід; згинання й розгинання рук в упорі лежачи; підтягування у висі лежачи) жінок 36–39 та 40–44 років за показниками вищезгаданих тестів свідчать про негативну динаміку змін фізичної підготовленості зі збільшенням віку досліджуваних.

Актуальність. Підтримання високого рівня бойової здатності військовослужбовців є першочерговим завданням Збройних сил задля успішного виконання завдань за призначенням. Професійна діяльність офіцерів висуває нові вимоги, із якими випускники кафедр підготовки офіцерів запасу раніше не стикалися в повсякден- ному житті. Насамперед це постійна готовність виконувати завдання військово-професійної діяльності в будь- який час і за будь-яких умов. Отже, актуальним питанням залишається формування військово-прикладних навичок студентів ЗВО в процесі фізичного виховання, які дають змогу оптимізувати процес пристосування випускників КПОЗ до умов військової діяльності й виконання бойових завдань. Мета роботи – визначити ефективність впливу фізичного виховання на формування військово-прикладних навичок студентів закладів вищої освіти, які навчаються на кафедрі підготовки офіцерів запасу. Методи – аналіз наукової й методичної літератури, тестування, методи математичної статистики. Результати. Виявлено, що результати, отримані під час тестування фізичної підготовленості студентів, не відповідають вимогам Інструкції з фізичної підготовки в системі Міністерства оборони України для випускників ЗВО. Водночас аналіз вступних іспитів із фізичної підготовки цих студентів на військову кафедру виявив, що всі респонденти під час випробувань проде- монстрували позитивні результати з фізичної підготовки. Висновки. Проведені дослідження дали змогу з’ясувати, що офіцери, які отримали вищу освіту в закладах вищої освіти та одночасно навчалися за програмою підготовки офіцерів запасу, мають низькі результати з фізичної підготовленості. Крім того, вони виявилися не здатними організовувати й проводити фізичну підготовку з підлеглим особовим складом. Це пов’язано з не розвʼязаними раніше проблемами системи військової освіти, а проблемні питання низького рівня загально- військової підготовки офіцерів запасу командири та начальники різних рівнів намагалися вирішити за рахунок підвищення якості й обсягу професійної підготовки.

Актуальність. Сучасний рівень розвитку фізичної підготовки та вимоги, які вона висуває до людини, котра розвивається, вимагають максимальної мобілізації фізичних і психічних сил захисника, професійної підготовки для успішного виконання завдань за призначенням. Відомо, що військово-спортивні багатоборства забезпечують ефективний розвиток необхідних фізичних якостей, що в подальшому застосовуються під час виконання завдань за призначенням. Військово-спортивні багатоборства є ефективним засобом фізичного розвитку основних фізичних якостей і навчання навичок самооборони, а також забезпечують здатність швидко реагувати на раптово мінливу обстановку, набуття впевненості та рішучості у власних силах. Саме тому вони повинні органічно поєднуватися з традиційними засобами фізичного виховання майбутніх спеціалістів у справі формування військово-професійної фізичної культури особистості. У статті досліджено корекцію ситуативної характеристики діяльності, яка полягає в невизначеності її результату та можливих несприятливих наслідків у випадку неуспіху курсантів вищих військових навчальних закладів. Мета роботи – дослідити вплив занять військово-спортивним багатоборством на показники професійно важливих психологічних показників курсантів закладів вищої освіти. Методи – аналіз наукової та методичної літератури, психодіагностичне тестування, методи математичної статистики. Результати. До дослідження залучено 74 курсанти контрольної групи, які навчалися за чинною системою фізично підготовки, та 47 курсантів експериментальної групи, котрі займалися в секції військово-спортивного багатоборства. Вік досліджуємих – від 17 до 26 років. У ході експерименту про- ведено дослідження показників ступеня готовності до ризику. Протягом експерименту в курсантів ЕГ відбулося статистично достовірне покращення середніх значень цього показника (р<0,05). Висновки. За результатами дослідження відбулося покращення показників готовності до ризику.

Dostoiévski e a vitória das visões de mundo
Authors: Drucker Cláudia
Published: August 2023

O artigo discute a atualidade da polêmica que Dostoievski trava com a doutrina niilista na novela Memórias do subsolo. Niilistas, no sentido russo, são os jovens de vanguarda que sustentam um tipo de socialismo científico, ou melhor, tecnocrático. Dostoiévski explica a síntese niilista, que visa demonstrar como a justiça, a virtude, os afetos e a racionalidade cooperam em perfeita harmonia, e formula objeções. A crítica de Dostoiévski aos regimes tecnocráticos e burocráticos, não importa quão bem-intencionados sejam, soam hoje bem já conhecidas, pois foram adotadas seguidamente pela posteridade. No artigo se sugere que a polêmica de Dostoiévski é parcialmente independente de um conteúdo específico. A caracterização do niilismo aponta a possibilidade de surgirem novas visões de mundo de base não mais claramente religiosa ou científica, e de o debate público ser dominado por posições inconciliáveis.
O que é que um homem faz? De Clarice Lispector a Dostoiévski
Authors: Moraes Marcella Assis de
Published: August 2023

Este trabalho propõe uma relação entre Fiódor Dostoiévski e Clarice Lispector, particularmente entre o romance Crime e castigo, de 1866, e o romance A maçã no escuro, de 1961. A relação entre os dois é evidente – Dostoiévski está reconhecidamente entre as fontes desta obra de Lispector. Este artigo privilegia um dos pontos de contato entre os dois: o de uma discussão em torno da noção de agência, em tensão com a de passividade. O objetivo é demonstrar a maneira como ambos os romances perturbam o estabelecimento de um binômio que identificaria duas instâncias opostas – agência e passividade aqui não se opõem, mas participam de uma imbricação. Assim, o que se investiga, nessas obras, é uma questão ética: o que é, afinal, agir? Para tanto, pontuam-se discussões teóricas como a diferença entre homens e animais, e retomam-se lugares críticos como a relevância do conflito trágico na obra de Dostoiévski. Assim, encaminha-se um pensamento da ação, sobretudo a partir da hesitação entre a abstração e a realização, que um ato é, afinal, capaz de concentrar.

Authors: Cerávolo Eduardo Fujiwara , Hochheim Norberto
Published: August 2023

Frente às incertezas provocadas pela instabilidade do mercado brasileiro nos últimos anos e à longa duração e inflexibilidade característicos dos projetos de construção civil, é essencial que seja feita uma análise econômico-financeira adequada considerando os principais fatores internos e externos ao projeto, as suas possíveis variações ao longo do tempo e as consequências disso no resultado do empreendimento. O objetivo deste trabalho é analisar como as correlações que podem existir entre as variáveis consideradas num modelo de simulação de Monte Carlo afetam os resultados de uma análise de investimento imobiliário. Também é apresentada uma forma de considerar a incerteza na taxa de desconto a partir de observações de mercado. Para alcançar estes objetivos são estudados os processos envolvidos na obtenção dos dados e na definição dos parâmetros a serem usados no modelo, delimitando faixas de variação para as principais variáveis do projeto, num estudo de caso desenvolvido para um empreendimento comercial na cidade de Florianópolis. As simulações de Monte Carlo permitiram estudar as probabilidades de concretização das diferentes faixas de resultados, concluindo que, segundo os parâmetros usados, este investimento tem baixo risco e alta probabilidade de ser atrativo ao investidor.

Pseudo-static slope stability analysis and numerical settlement assessment of rubble mound breakwater under hydrodynamic conditions
Authors: Navid Joushideh  , Sara Shomal Zadeh  , Behrokh Bahrami  , Nasim Shakouri Mahmoudabadi
Published: August 2023

This research focuses on the slope stability analysis of rubble mound breakwaters using the Bishop method, with a specific application to the Chamkhaleh Port in the Caspian Sea region. The study emphasizes the criticality of slope stability in coastal engineering to protect shorelines from erosion and damage caused by waves and currents. The Bishop method is employed in the analysis, allowing a comprehensive assessment of breakwater stability by considering soil properties, slope geometry, and external forces. Sensitivity analysis is conducted to evaluate the impact of various parameters on breakwater stability, enabling optimization of the design and identification of potential failure mechanisms. Additionally, the research addresses numerical settlement analysis using the finite element method. The finite element method proves effective in handling complex geometries and boundary conditions, accurately capturing deformational changes caused by breakwater construction under short-term and long-term conditions. The settlement analysis results indicate acceptable maximum settlements within the project area. To ensure the reliability of the breakwater, geotechnical investigations are conducted to determine the minimum channel slope and allowable distance from the breakwater edge, crucial parameters for achieving acceptable static and pseudo-static safety coefficients. The breakwater's overall stability is assessed, and the factor of safety is quantified to evaluate the probability of slope failure and associated risks. The findings demonstrate the satisfactory stability and settlement performance of the Chamkhaleh breakwater project, affirming its effectiveness in providing coastal protection for the port.
Seasonal Variation of Laboratory Animals as a Consideration for Research Reproducibility
Authors: Suckow Mark A , Tirado-Muñiz Noé
Published: August 2023

Laboratory rodents are generally maintained under standardized conditions in order to control the effects of extrinsic factors on research. However, despite attempts to standardize conditions, variability can nonetheless confound efforts directed toward research reproducibility. Here
we explore some of the existing literature on the potential impact of seasonal variability as an extrinsic factor that can potentially impact research results. We discuss the influence of seasonal changes in association with an internal clock mechanism that might account for such variation,
noting that the mechanisms and interactions of seasonal and internal time-keeping remain largely undetermined. Finally, we speculate that seasonal changes experienced by personnel who handle animals may influence the animals in ways that result in physiologic and behavioral changes.
Wirtschaftliche Resilienz durch Subventionen? Anmerkungen aus ökonomischer Perspektive
Authors:   FH Münster, Rupprecht Manuel
Published: August 2023

Die Weltwirtschaft steht unter Spannung. Schon seit Jahren stockt die Globalisierung, Handel, Produktions- und Kapitalverflechtungen entwickelten sich bestenfalls seitwärts. In jüngster Zeit sorgten mit der Pandemie, den zunehmenden geopolitischen Spannungen – vor allem, aber nicht nur – zwischen den USA und China sowie dem Ukraine-Krieg gleich drei Entwicklungen für zusätzliche Verwerfungen. Lieferketten brachen, Vorprodukte fehlten, Produktion fiel aus. Entsprechend groß ist nun der Wunsch nach Unabhängigkeit. Den Weg dahin sollen vielerorts Subventionen bereiten. In einigen Bereichen ist diesbezüglich ein regelrechter Wettbewerb entbrannt. Wie dieser Wettbewerb aussieht, welche Vor- und Nachteile mit Subventionen einhergehen und wie der eingeschlagene Weg aus ökonomischer Sicht zu bewerten ist, ist Gegenstand dieses Beitrags.
The Power of People in Pandemic Times – Driving Supply Chain Resilience through Corporate Culture
Authors:   Department of Supply Chain Management and Logistics, Cooperative State University (DHBW) Mannheim, Germany, Hohenstein Nils-Ole
Published: August 2023

The assertion “Our people are what set us apart from our rivals” is a common statement made by nearly every company, highlighting the significance of their people as the most valuable asset. Similarly, a corporate culture emphasizing risk awareness and learning from experiences has played a key role in shaping supply chain resilience (SCRES) amidst competitive dynamics in response to the COVID-19 pandemic. Employee engagement, communication, and collaboration, as dimensions of SC risk awareness, determine the effectiveness of firms’ cultures in handling large-scale disruptions with robustness and agility. Additionally, the COVID-19 crisis has had a positive impact on firms’ learning orientation. The crucial necessity of digital supply chain (SC) transformation to enhance SCRES under pandemic conditions has further reinforced the need for dynamic adaptation and reconfiguration of firms’ culture and employee skillsets through digital upskilling.
