A 38 year-old woman, who was previously fit and well, presented with a 10 day history of fever and non-specific symptoms. Initial chest X-ray demonstrated patchy nodular infiltrates bilaterally. She became increasingly hypoxaemic. Cultures to this point were all negative. A high-resolution CT thorax showed diffuse multilobular ground glass appearance with peripheral nodular shadowing, consistent with a viral pneumonia. CMV IgM antibody was positive and CMV PCR was positive on two subsequent occasions. She was commenced on oral valganciclovir. She made a full recovery and was discharged seven days later.
A hot bath to calm what ails you – the Cannabis Hyperemesis Syndrome
Authors:   Whittington Hospital, London, Luther V , Luther V ,   Whittington Hospital, London
Published: June 2021

Abstract The Cannabis Hyperemesis Syndrome (CHS) defines a recently described paradoxical association between recurrent vomiting episodes, daily cannabis excess and symptomatic relief with a hot bath or shower. Importantly, symptom resolution only occurs with cessation of cannabis use. We describe a case of CHS which had resulted in repeated hospital admissions. As cannabis use is common, it is important for both patients and Acute Physicians to be aware of this increasingly recognised condition

Serum Potassium Levels and Mortality in Acute Myocardial Infarction Goyal A et al. JAMA. 2012; B157-164 The importance of potassium homeostasis in the post-infarction period has become a cornerstone in modern clinical practice. Several studies have shown that potassium levels of less than 3.5 led to a higher risk of arrhythmia induction. This study investigated what the optimal target potassium level should be, given the lower rates of serious arrhythmias following interventions such as beta-blockade and reperfusion therapy.

An Acute Medical Unit has recently been established at York Hospital. The present study sought to characterise the case mix of acutely unwell medical patients to allow identification of priorities for ongoing service development and to assess educational opportunities for trainees in the region. Data were collected for 16001 admission episodes between January 2010 and April 2011 inclusive. These allowed characterisation of the case mix, and identified key priorities where clinical pathway do not yet exist, namely heart failure, urinary tract infection, and acute diarrhoea. Good educational opportunities exist for most aspects of the Acute Medicine curriculum; several weaknesses were identified, and trainees might address these by undertaking a specific period of specialty training in endocrinology and neurology.

24 hour availability of echocardiography in Acute Medicine: time to get out of our ‘silos’!
Authors:   Airedale NHS Foundation Trust, Skipton Road, Steeton, Keighley BD20 6TD, Droste Jan
Published: June 2021

Dear Sir, I read with interest the article by Ravikirti et al in the recent edition of Acute Medicine. The authors rightly highlight the potential for atypical presentations of tamponade following cardiac surgery, which has been reported previously. The investigation of any acutely unwell patient presenting after cardiac surgery should include some form of cardiac imaging. In the cases described the diagnosis was delayed, in part, due to the lack of an echocardiography service out-of-hours.

Euglycaemic ketoacidosis is a rare endocrine emergency, which can have disastrous consequences if left undiagnosed. We present the case of a 57 year old man with type 2 diabetes who developed ketoacidosis (DKA) following a myocardial infarction, despite being normoglycaemic, following discontinuation of his insulin infusion in an intensive care setting. The case highlights the importance of capillary ketone body testing in this scenario as well as the dangers of an over reliance on blood glucose values in the diagnosis of ketoacidosis. The notion that DKA can occur in both type 1 and type 2 diabetes is reaffirmed and the value of adequate insulin therapy in euglycaemic ketoacidosis is emphasized.

Turkish Parents’ Attitudes Towards Strength and Aerobic Exercises in their Children: A Replication of Ten Hoor et al. (2015)
Authors: Varol Tugce , Ten Hoor Gill A.
Published: June 2021

In this study, parental attitudes towards aerobic and strength exercises from Turkish parents were examined. In a first study, interviews were conducted with 10 Turkish parents (4 mothers, 6 fathers). In a second study, a Dutch study by ten Hoor et al. (2015) was replicated in Turkey after which data was cautiously compared to examine if there are any cultural differences. A total of 321 Turkish parents filled out an online survey regarding their own and their children’s physical activity, and more specifically, their attitudes towards aerobic and strength exercises. Overall, study 1 showed that Turkish parents were positive about their children’s strength exercises. Similar to the study by Ten Hoor et al. (2015), study 2 demonstrated that Turkish parents had more positive attitudes for aerobic exercises compared to strength exercises. Cautious comparisons between Dutch and Turkish parents generally showed no differences. Turkish parents with negative attitudes towards strength exercises of their child provided similar reasons compared to the Dutch sample. In conclusion, Turkish and Dutch parents have similar opinions regarding physical activity and its types. For Turkish parents, negative attitudes about strength exercises are based on misperceptions – similar to what was found in Dutch parents. Future interventions are needed to deal with those misperceptions.

Spinopelvic Biomechanics and Total Hip Arthroplasty: A Primer for Clinical Practice
Authors: Heckmann Nathanael D. , Lieberman Jay R.
Published: June 2021

Abnormal spinopelvic motion from spine pathology is associated with inferior outcomes after total hip arthroplasty, including inferior patient-reported outcomes, increased rates of instability, and higher revision rates. Identifying these high-risk patients preoperatively is important to conduct the appropriate workup and formulate a surgical plan. Standing and sitting lateral spinopelvic radiographs are able to identify and quantify abnormal spinopelvic motion. Depending on the type of spinopelvic deformity, some patients may require increased anteversion, increased offset, and large diameter heads or dual mobility articulations to prevent dislocation. This review article will provide the reader with practical information that can be applied to patients regarding the terminology, pathophysiology, evaluation, and management of total hip arthroplasty patients with spinopelvic pathology.
ABCs of Pain: A Functional Scale Measuring Perioperative Pain in Total Hip Arthroplasty Patients
Authors: Hierl Anneliese N. , Moran Hannah Kang , Villwock Mark R. , Templeton Kimberly J. , Villwock Jennifer A.
Published: June 2021

Introduction:

Functional pain assessments are critical in total hip arthroplasty. This pilot study investigated a novel functional pain scale—the Activity-Based Checks of Pain (ABCs)—and its correlations with the 0 to 10 numeric rating scale (NRS) and outpatient milligram of morphine equivalents (MMEs) prescribed and needed in the first 2 weeks after total hip arthroplasty.

Methods:

ABCs and NRS were collected at the baseline, inpatient, and 2-week follow-up. Primary outcome metrics were needed for pain medication at the time of pain scale completion, MMEs prescribed at discharge, and MMEs taken. Individual ABC functions and composite score were analyzed using Spearman rho and Mann-Whitney U tests

Results:

ABC and NRS scores were greatest preoperatively (n = 39). At each stage, the ABCs correlated with the NRS (ρ = 0.450, P < 0.01; ρ = 0.402, P < 0.05; and ρ = 0.563, P < 0.01). ABC or NRS scores did not correlate with MMEs prescribed. Last in-house NRS correlated with MMEs taken postoperatively (r = 0.571, P < 0.01). Specific ABCs functions—“sitting up” (ρ = 0.418, P < 0.01), “walking in room” (ρ = 0.353, P < 0.05), and “walking outside room” (ρ = 0.362, P < 0.05)—on the day of discharge correlated with MMEs taken.

Conclusion:

ABCs scale correlates with NRS. Neither scale correlated with MMEs prescribed at discharge, suggesting pain is undervalued in analgesic planning. Clinicians should assess pain with functions found to correlate with MMEs taken—“sitting up,” “walking in room,” and “walking outside room.”
Quaternary Element Incorporation Effects on Thermal Properties and Crystal-Micro Structure of Cu-Al-Fe High Temperature Shape Memory Alloys
Authors: BALCİ Esra , AKPINAR Sinan
Published: June 2021

Recently, researchers have shown an increased interest in Cu-based shape memory alloys due to their special characteristics, which can be used in high-temperature applications. In this study, ternary shape memory alloys in the form of CuAlFe with different ratios of iron and quaternary CuAlFe alloys containing Ni, Mn, and Ti were produced by arc melting. Then the produced alloys were kept at 900 ℃ for 24 hours to make sure that all constituents in the alloys were homogeneously distributed. The change in the transformation temperatures for all samples was checked out by Differential Scanning Calorimetry (DSC). Also, the change in the crystal structure and microstructure were determined by x-ray diffractometer (XRD) and scanning electron microscopy (SEM), respectively. The aim of this study is to compare the thermal and microstructural properties of quaternary alloys formed by adding Ni, Mn, and Ti elements to CuAlFe-based shape memory alloy with different rates, which is not available in the literature. The result of this study; although the electron concentration value increased, a significant decrease was observed in the values of the transformation temperatures. Increasing Fe-element decreased the transformation temperature non-linearly. Ni and Mn contents added to CuAlFe shape memory alloys have reduced transformation temperatures, such as Af and Mf. The XRD and SEM-EDX measurements showed the martensite phase with some produced compound precipitated in the matrix phase.
Enriched Oxygen for Crude Oil Preheating in Petroleum Refining
Authors: ALQAHEEM Yousef , ALOMAİR Abdulaziz
Published: June 2021

The crude distillation unit is one of the energy-intensive processes in the refinery. This is because of the crude preheater that suffers from excessive energy loss due to the use of air in the combustion furnace. Alternatively, fuel combustion by enriched oxygen can improve heat efficiency, minimize fuel consumption and reduce emissions. In this paper, enriched oxygen has been simulated by UniSim for preheating Kuwaiti crude in one of the distillation columns in the Clean Fuels Project. Results show that the use of 30 mol% of concentrated oxygen reduced fuel consumption by 5%. Carbon dioxide emissions were also minimized by 22,240 tons per year. A membrane system made from perfluoropolymer was simulated for the production of 5,298 tons of enriched oxygen (per day) and it required an area of 39,000 m2 with a capital investment of 6.9 million $.

Published: June 2021

Entropy is producing during any irreversible process. In the cancer cells, the entropy generation measures the irreversibility; so, the cancer cells have higher entropy generation than the healthy cells. The entropy generation rate shows the amount of robustness, progression, and invasion of the cancer cells. From a thermodynamic aspect, cancer's origin and growth is an irreversible process, and the thermodynamic variables such as the cell volume, temperature, and entropy will change during this process. In this paper, a procedure based on experimental data is proposed to calculate dynamic entropy generation in the tumoral tissues by dynamic thermography and measurement of tumor size. The dynamic changes in the volume, temperature, and entropy associated with tumor cells over time are tested and evaluated in this regard. An in vivo assay has been developed to measure and analyze these changes. This assay investigated the growth of 4T1 Breast Tumor in 55 BALB/c mice over time. Infrared thermography has been employed to evaluate dynamic temperature changes of the tumors. The computer code has been developed to gather important data from tumoral and healthy mice's images to compute considered temperature differences and entropy generation associated with tumoral tissues. To better evaluate tumor tissue, the Micro PET Images are used to verify volume changes of tumors. The relation between the volume and temperature gradient of tumor cells has detected by measuring during the experiment. The entropy of tumor cells was studying and calculating during the process of tumor changes. Results show that entropy generation as the main concept of thermodynamic is a strong tool for the analysis of cancer cells and has a strong relationship with cancer growth.
RINGS WITH A DERIVATION WHOSE IMAGE IS ZERO ON THE ASSOCIATORS
Authors: YEN CHEN-TE
Published: June 2021

Let $R$ be a nonassociative ring, $N$, $M$, $L$ and $G$ the left nucleus,middle nucleus, right nucleus and nucleus respectively. Assume that $R$ is a ring with a derivation $d$ such that $d((R, R, R)) = 0$. It is shown that if $R$ is a simple ring then either $R$ is associative or $d(N \cap L) = 0$; and if $R$ is a prime ring satisfying $Rd(G) \subseteq N$ and $d(G)R \subseteq L$, or $d(G)R +Rd(G) \subseteq M$ then either $R$ is associative or $d(G) =0$. These partially extend our previous results.

that are regular in the punctured disk $E = \{z : 0 < |z| < 1\}$ and satisfy
\[\text{Re}\left\{\frac{z(D^{n+p-1}f(z))'}{D^{n+p-1}f(z)}\right\}<-\alpha\]

En este trabajo se presenta una investigación en enseñanza de la física general en la que la ecuación hidrodinámica de Bernoulli es instruida en tres cursos de estudiantes de ingeniería con un método activo que incorpora el uso de experimentos discrepantes. Para determinar el aprendizaje de tal ecuación se usa el pre/postest con un cuestionario sobre la ecuación previamente validado en el marco de la teoría clásica del test. El aprendizaje de la ecuación se analiza con la ganancia de Hake indicando la efectividad del método. Para revelar el cambio conceptual en la población intervenida y de control se usan los vectores de evolución de Bao. Se ha encontrado que el método activo presenta mayores ganancias que el método tradicional en más del doble del valor. Además, los vectores de Bao revelan que el grupo con método activo tuvo una mejor evolución conceptual que el grupo control.
Construyendo conceptos sobre electricidad en infantil mediante actividades de indagación
Authors: Calo Mosquera Nuria , García-Rodeja Gayoso Isabel , Sesto Varela Vanessa
Published: June 2021

Se presenta un estudio que tiene por objetivo describir la implementación de una propuesta donde niños de educación infantil construyen conceptos y generalizaciones a través de la experiencia empírica y el diálogo con otros al implicarse en actividades de indagación con circuitos eléctricos. Los participantes son niños (4 a 5 años) de una clase de educación infantil. Las sesiones fueron grabadas y analizadas. Los resultados muestran que los niños entienden la electricidad como un ente que permite que las cosas funcionen. En general, no tienen dificultad para identificar aparatos eléctricos y electrónicos. A medida que se implementa la actividad los niños llegan a la generalización inductiva de que los objetos de metal conducen la electricidad. Se observa que los niños muestran más dificultad en aplicar esta idea para hacer predicciones que para justificar las observaciones realizadas.
Metodologias ativas: efeitos de verdade acerca da inovação no ensino dentro da racionalidade neoliberal

Published: June 2021

A inovação tornou-se um imperativo na sociedade contemporânea. Nela, à docência universitária é convocada a utilizar metodologias ativas como forma de inovar no ensino. Divulga-se que essas metodologias produzem sujeitos ativos e autônomos. Nesse sentido, neste artigo busca-se compreender os efeitos de verdade acerca das metodologias ativas na produção de estudantes ativas/os. Ele traz parte dos resultados de uma pesquisa, cujo corpus é constituído pelos ditos em circulação no curso de formação de professoras/es universitárias/os, bem como de entrevistas realizadas com participantes dessa formação. Utilizou-se como referencial as ferramentas teóricas e analíticas do filósofo Michel Foucault, a saber: dispositivo, discurso, poder e verdade. Por meio da rede metodológica que articulou elementos da netnografia educacional, de entrevistas narrativas e da análise do discurso de inspiração foucaultiana, desenvolveu-se o argumento de que a docência inovadora está em continuidade com a produção da posição de sujeito discipulus iacto. Conclui-se que as demandas postas à docência universitária inovadora, para utilizar metodologias ativas, atendem à urgência de forjar a posição de sujeito discipulus iacto na racionalidade neoliberal. As demandas pelo uso de metodologias ativas, portanto, governam as condutas discentes e docentes no ensino universitário inovador.
Formação docente e trabalho educativo na educação infantil: algumas reflexões
Authors: Both Ilaine Inês , Bissoli Michelle De Freitas
Published: June 2021

A formação docente superficial e pragmática colabora para o esvaziamento do trabalho educativo e do processo de humanização. Esses fenômenos se coadunam com as limitadas condições de vida e de educação da ampla maioria das mulheres e dos homens do nosso país, fruto da estrutura social vigente, organizada na lógica do capital. Essa afirmação resulta da pesquisa de doutorado, vinculada ao Programa de Pós-Graduação em Educação (PPGE), da Universidade Federal do Amazonas (UFAM), que analisou, sob a luz da Teoria Histórico-Cultural e da Pedagogia Histórico-Crítica, elementos do trabalho educativo desenvolvido em 2014, com crianças da pré-escola de uma escola pública municipal de Manaus, Amazonas. A observação participativa em uma turma frequentada por vinte crianças de 4 e 5 anos de idade e o Grupo Focal com três professoras da pré-escola foram os instrumentos principais da pesquisa de campo. O estudo demonstra que o trabalho educativo, categoria central dessa pesquisa, foi predominantemente caracterizado pelo pragmatismo e espontaneísmo, o que contribui para a manutenção do acentuado estado de desumanização de professores e crianças. A superação dessa situação passa pela socialização do conhecimento em sua forma mais elaborada, função precípua da escola. Para tanto, apontamos a unidade dialética entre a teoria e a prática na formação docente como uma das possibilidades para a necessária e desafiadora busca do aprimoramento do trabalho educativo na Educação Infantil.

The Gulf of Mexico Research Initiative (GoMRI) was created in 2010 following the catastrophic Deepwater Horizon explosion and oil spill. BP engaged Rita Colwell to form and lead an independent board of experts to oversee an unprecedented program of scientific research on the effects of the spill. As a new and uniquely funded organization, GoMRI quickly developed and implemented a set of management processes, policies, and frameworks while simultaneously building an interconnected research community that eventually grew to nearly 4,500 individuals. The GoMRI Research Board and Management Team successfully produced and operated a system for requests for proposals, grants management, scientific and programmatic data management, and outreach and education, and assembled a scientific synthesis of results to create a lasting legacy 10 years after the disaster. Here, we document the challenges and key decisions underlying the design and operation of GoMRI as a model for independent, industry-funded research. In short, GoMRI represents a unique multi-sector partnership and a community of researchers that will advance science in the Gulf of Mexico and elsewhere for decades to come.
What Was Released? Assessing the Physical Properties and Chemical Composition of Petroleum and Products of Burned Oil
Authors: Rullkötter Jürgen , Farrington John
Published: June 2021

The severity of oil spills depends on the quantity of material released and its physical and chemical properties. The total amount of petroleum spilled during the Deepwater Horizon incident and the relative fractions of the chemical compound classes of the Macondo oil were obtained by measurements, observations, and model calculations, with a significant amount of uncertainty. Because petroleum is an extremely complex mixture of many thousands or more of gaseous, liquid, and solid constituents, full elucidation of their compositions at the molecular level is impossible with presently available analytical techniques. This paper reviews published work on widely used analytical techniques and points out that scientists’ varying approaches to research questions and preferences for methods of analysis constitute a source of uncertainty. In addition, the focus is on two technical advancements developed over the last two decades, namely two-dimensional gas chromatography and Fourier transform ion cyclotron resonance mass spectrometry. Both were particularly valuable in the analysis of the spilled Macondo oil and its weathering products. Among the different processes of alteration of the original oil, only in situ oil burning is dealt with in this paper. This review reveals the paucity of data on this mitigation process and shows the need for more systematic coordination of methods in burned oil research studies.
Biogeochemical Processes Affecting the Fate of Discharged Deepwater Horizon Gas and Oil: New Insights and Remaining Gaps in Our Understanding
Authors:   Woods Hole Oceanographic Institution, Farrington John , Overton Edward , Passow Uta
Published: June 2021

Research funded under the Gulf of Mexico Research Initiative provided new insights into the biogeochemical processes influencing the fate of petroleum chemicals entering the Gulf of Mexico from the Deepwater Horizon (DWH) accident. This overview of that work is based on detailed recent reviews of aspects of the biogeochemistry as well as on activities supported by the US Natural Resource Damage Assessment. The main topics presented here are distribution of hydrocarbons in the water column; the role of photo-oxidation of petroleum compounds at the air-sea interface; the role of particulates in the fate of the DWH hydrocarbons, especially marine oil snow (MOS) and marine oil snow sedimentation and flocculent accumulation (MOSSFA); oil deposition and accumulation in sediments; and fate of oil on beaches and in marshes. A brief discussion of bioaccumulation is also included. Microbial degradation is addressed in a separate paper in this special issue of Oceanography. Important future research recommendations include: conduct a more robust assessment of the mass balance of various chemical groupings and even individual chemicals during specific time intervals; seek a better understanding of the roles of photo-oxidation products, MOS, and MOSSFA and their relationships to microbial degradation; and determine the fates of the insoluble highly degraded and viscous oil residues in the environment.

Gulf of Mexico (GOM) ecosystems are interconnected by numerous physical and biological processes. After the Deepwater Horizon (DWH) disaster, these ecological processes facilitated dispersal of oil-spill toxicants or were damaged and broken. A considerable portion of post-DWH research focused on higher levels of biological organization (i.e., populations, communities, and ecosystems) spanning at least four environments (onshore, coastal, open ocean, and deep benthos). Damage wrought by the oil spill and mitigation efforts varied considerably across ecosystems. Whereas all systems show prolonged impacts because of cascading effects that impacted functional connections within and between communities, deep-sea and mesopelagic environments were particularly hard hit and have shown less resilience than shallow environments. In some environments, such as marshes or the deep-sea benthos, products from the spill are still biologically accessible. Some shallow ecosystems show signs of recovery, and populations of some species show resilience; however, a return to a “pre-spill” state is questionable. Importantly, habitats in which large amounts of energy flow through the ecosystem (marshes, coastal regions) recovered more quickly than low energy habitats (deep-sea benthos). Functional interactions between Gulf of Mexico systems are more complex and widespread than generally recognized. Moreover, ecosystems in the Gulf are subject to multiple stressors that can combine to impart greater, and less predictable, impacts. To help mitigate the effects of future insults, we identified four salient areas of research that should be addressed for each of the major environments within the GOM: establishing monitoring systems; quantifying coupling between GOM ecosystems; developing criteria for assessing the “vulnerability” and “resilience” of species, communities, and ecosystems; and developing holistic predictive modeling.

Previous oil spills provide clear evidence that ecosystem restoration efforts are challenging, and recovery can take decades. Similar to the Ixtoc-I well blowout in 1979, the Deepwater Horizon (DWH) oil spill was enormous both in volume of oil spilled and duration, resulting in environmental impacts from the deep ocean to the Gulf of Mexico coastline. Data collected during the National Resource Damage Assessment showed significant damage to coastal areas (especially marshes), marine organisms, and deep-sea habitat. Previous spills have shown that disparate regions recover at different rates, with especially long-term effects in salt marshes and deep-sea habitat. Environmental recovery and restoration in the northern Gulf of Mexico are dependent upon fundamental knowledge of ecosystem processes in the region. Post-DWH research data provide a starting point for better understanding baselines and ecosystem processes. It is imperative to use the best science available to fully understand DWH environmental impacts and determine the appropriate means to ameliorate those impacts through restoration. Filling data gaps will be necessary to make better restoration decisions, and establishing new baselines will require long-term studies. Future research, especially via NOAA’s RESTORE Science Program and its state-based Centers of Excellence, should provide a path to understanding the potential for restoration and recovery of this vital marine ecosystem.

The Cogito Paradox
Authors: Cusmariu Arnold ,   Romanian Academy - Iasi Branch
Published: June 2021

The Cogito formulation in Discourse on Method attributes properties to one conceptual category that belong to another. Correcting the error ends up defeating Descartes’ response to skepticism. His own creation, the Evil Genius, is to blame.
Looking for Black Swans
Authors: Duggan Michael F. ,   Romanian Academy - Iasi Branch
Published: June 2021

This article examines the basis for testing historical claims and proffers the observation that the historical method is akin to the scientific method in that it utilizes critical elimination rather than justification. Building on the critical rationalism of Karl Popper – and specifically the deductive component of the scientific method called falsification – I examine his tetradic schema and adapt it for the specific purpose of historical analysis by making explicit a discrete step of critical testing, even though the schema is adequate as Popper expresses it and the elimination of error occurs at all steps of analysis. I also add a discrete step of critical elimination to Popper’s schema even though the elimination of error occurs at every step of analysis. The basis for critical elimination history is the demonstrable counterexample. The study of history will never approach the precision of science – history deals with open systems that cannot be replicated like experiments guided by fundamental laws. But just because we cannot know something with the rigor of science does not mean that we cannon know it better than we do. There may be no objective truth in an absolute sense, but there is a distinction to be made between well-tested and poorly tested theories and therefore between history done well and history done with less analytical rigor. What I hope to show is how our historical knowledge may progress through good faith critical discussion – history is discussion – and the elimination of error.
Pack a Truck: Decontextualizing and Contextualizing a Task

We describe how a group of eighth-grade students reasoned abstractly and quantitatively after the teacher fostered their engagement by using moves such as inviting students to draw and revoicing talk in a real-world context task.
L’engagement d’une région dans un processus de construction de compétences
entrepreneuriales territoriales : le cas d’un programme de recherche en région
Centre-Val de Loire
Authors: Lebègue Typhaine , Evon Juliette , Hulin Annabelle , Gavoille Franck
Published: June 2021

La notion de compétences entrepreneuriales est souvent traitée à l’échelle
individuelle, mais plus rarement à l’échelle territoriale ou régionale. Or, la
région est un lieu privilégié d’interactions entre acteurs, ressources et
institutions et constitue de ce fait un territoire propice aux dynamiques
d’innovation. Ce papier développe tout d’abord un cadre théorique mettant en
évidence les liens ténus qui apparaissent entre les ressources et compétences d’un
territoire régional, sa dynamique et l’entrepreneuriat. Puis, en s’appuyant sur un
programme régional dédié à la production d’une innovation thérapeutique (les
biomédicaments) en Région Centre-Val de Loire, cette recherche propose un cadre
d’analyse du processus de construction de compétences entrepreneuriales
territoriales (CET).
Les compétences entrepreneuriales du dirigeant au coeur de l’émergence d’un réseau international de PME
Authors: Gallego-Roquelaure Virginie , Adla Ludivine
Published: June 2021

L’objectif de cet article est d’apporter des connaissances sur l’émergence d’un réseau international de PME au travers de l’analyse des compétences entrepreneuriales du dirigeant. Dans cette optique, l’approcheResource Based Viewet plus particulièrement les travaux de Barney et Clark (2007) ont été mobilisés. L’étude longitudinale et rétrospective d’un cas émergent de réseau de PME révèle trois étapes clés : l’identification de l’opportunité d’un réseau international impulsée par la mobilisation du capital humain et relationnel, l’évaluation de l’opportunité s’appuyant sur l’animation du capital humain et relationnel, et l’exploitation de l’opportunité nécessitant la coordination du capital humain et relationnel.
Les IDE dans les pays d’Europe centrale et orientale : une approche gravitationnelle
Authors: Brahim Mariem , Guesmi Khaled , Teulon Frédéric
Published: June 2021

Cet article s’intéresse aux déterminants des investissements directs étrangers (IDE) européens dans les pays d’Europe Centrale et Orientale (PECO). Nous utilisons un modèle théorique permettant d’étudier les décisions des Firmes Multinationales. Deux estimations ont été effectuées : une coupe transversale sur la période (1996-2013) complétée par une méthode SURE (Seemingly Unrelated Regressions Method). Les variables macroéconomiques retenues (distance, intensité technologique, taille du marché, risque pays…) ont un impact déterminant sur les flux d’IDE, mais avec des résultats différenciés selon la méthode utilisée. Depuis le début des années 1990, l’attractivité des pays de l’Est est liée en grande partie aux perspectives ouvertes par leur adhésion à l’Union européenne, le choix de la méthode de privatisation des entreprises publiques a aussi joué un rôle. Pour les coûts salariaux les résultats obtenus sont plus ambigus : selon la coupe transversale l’impact est négatif et significatif, en revanche dans la méthode SURE, les résultats sont moins significatifs.
La tolérance du client face à l’échec d’une innovation de service : vers l’ouverture de la boîte noire du processus de récupération
Authors: Cusin Julien , Flacandji Michaël
Published: June 2021

Notre recherche étudie, dans la durée, le comportement des clients face à l’échec d’une innovation de service, ainsi que la récupération de service initiée par l’enseigne et ses conséquences. Le cas considéré est celui de l’échec d’un nouveau concept de magasin testé par un distributeur d’articles de sport. Notre démarche compréhensive longitudinale se fonde sur l’analyse d’avis en ligne et d’entretiens auprès de salariés et de clients. Nos résultats présentent finalement le processus par lequel les clients accordent un droit à l’erreur à une entreprise dont l’innovation de service a échoué.
Role of Objectives Alignment in Strategic Alliance Instability
Authors: Ben Jemaa-Boubaya Kaouther , Cheriet Foued , Smida Ali
Published: June 2021

The literature identifies strategic alignment as a chief determinant of the strategic alliances’ stability. Through a qualitative study based on five alliance study cases, this research aims to identify the different types of alignment and their impact on the instability. The results show that instability within an alliance can be due to the lack of alignment, i.e., of goals, agendas and structure. Differences between agendas, strategies, orientations and partners’ structures may require adjustment tools to strengthen the collaborative governance and come out of situations of instability within strategic alliances.

Authors: Desmarteau Robert H. , Saives Anne-Laure , Schieb-Bienfait Nathalie , Emin Sandrine , Boldrini Jean-Claude , Urbain Caroline
Published: June 2021

Cet article propose une revue critique et une modélisation du concept de « création de valeur » à partir d’une analyse de la littérature relative au modèle d’affaires. Les définitions de la création de valeur sont étudiées à partir des 50 articles anglophones les plus cités dont les titres contiennentvalueetcreation. L’analyse révèle cinq thèmes : nature de la valeur créée pour le client, architecture de la valeur par l’entreprise, valeur perçue par l’utilisateur, partage économique entre les parties prenantes, co-création de la valeur avec celles-ci. Notre discussion se construit autour d’enjeux épistémologiques dans une perspective pragmatiste.
Introduction
Authors: Delanoë Igor
Published: June 2021

La revendication du statut de puissance globale et souveraine se trouve au coeur du projet géopolitique porté pour son pays par Vladimir Poutine depuis son arrivée au Kremlin en 2000. Dans la compétition qui l’oppose aujourd’hui aux puissances affirmées ou montantes, globales ou régionales, sur la scène internationale la Russie dispose d’atouts indéniables, mais elle doit aussi composer avec des faiblesses. Ce dossier se propose d’examiner sous l’angle de la résurgence de la puissance cinq champs investis par le Kremlin dans sa logique de recomposition d’influence : l’Eurasie, le déploiement d’un soft power par Moscou, le vecteur asiatique de la politique étrangère de la Russie, la posture nucléaire russe et le cyberespace. Le décryptage proposé ici doit permettre, à travers l’analyse des succès et des échecs ainsi que la formulation de perspectives pour chacun de ces thèmes, de mieux cerner les contours d’une puissance russe en redéfinition face au nouveau désordre international.
La dissuasion nucléaire russe dans le désordre international et le contexte post-2014
Authors: Delanoë Igor
Published: June 2021

Alors que les relations entre la Russie et les États-Unis se sont considérablement dégradées depuis la crise ukrainienne, le dialogue stratégique entre Moscou et Washington sur le contrôle des armements connaît une panne sans précédent. Tandis que la Russie multipliait les « signaux nucléaires », le président russe a fait étalage de nouveaux armements hypersoniques en mars 2018, faisant redouter un abaissement du seuil d’emploi du feu nucléaire. En s’appuyant sur les documents officiels russes, en analysant les récentes améliorations constatées au sein des forces conventionnelles russes et en tenant compte des derniers éléments du débat stratégique portant sur la dissuasion nucléaire de la Russie, cet article vient nuancer l’idée répandue selon laquelle Moscou serait plus encline aujourd’hui à utiliser ses armes atomiques. En outre, le Kremlin reste fondamentalement intéressé par le maintien d’un cadre légal international portant sur le contrôle des armements auquel contribue le traité russo-américain New Start.
