There is a large literature on the composition of the boards as well as the monitoring role and the advisory role of the boards. Nevertheless, the problem of collusion between the CEO and the board has receive little attention. The aim of this paper is to study collusive aspects of the board of directors. Our paper sheds light on the problem of composition of the board of directors. We study what is the optimal composition of the board of directors in particular if it is preferable to have a insider-oriented board or a outsider-oriented board with a majority of independent directors. We consider that a board of independent directors that are all chosen directly by the CEO is a friendly board if the independent directors follow the decision of the CEO. We study the case of collusion considering a CEO facing a choice of projects.We propose a model where we have di¤erent projects each with a certain level of risk. The choice of the best project for the company is function of remuneration of the CEO as well as the private benefits of the CEO.

Focusing on homogeneous beliefs, we can distinguish two commonly shared ideas that, i) the competition between informed traders destroys their trading profits, ii) trading with a noisy signal brings about a loss in the expected profits. So far, it has been proved in the latter framework, that when N strategic and perfectly informed traders compete in the financial market, i) the informativeness of prices increases with the degree of competition and, ii) the aggregate and individual profits go to 0 when N is large. In this paper, we propose a general study where N strategic informaed agents have heterogeneous beliefs, i.e. are endowed with noisy information and compete à la Nash. We prove the existence and uniqueness of a linear equilibrium generalizing Kyle (1985) results to the case of N informed traders when the insiders have heterogeneous beliefs. In this general framework, we derive the following striking results: for certain regions of noise and numbers of competitors in excess of four, i) each individual expected profit is greater than the one obtained in the perfectly informed (and homogeneous beliefs) case; ii) the aggregate profit has a finite (strictly) positive limit when N is large. iii) Even when an infinite number of insiders compete in the market, the price is no longer efficient and does not fully reveal the final liquidation value of the risky asset. iv) In the particular case where each informed agent is endowed with a signal the precision of which is the same, a) we show that there exists an optimal level of noise for which each individual expected profit is maximized; b) we show that there exists an optimal size of the market for which the aggregate expectged profit is maximized; c) the liquidity is an increasing function of the number of informed traders but has a finite limit for large N; d) the informativeness of prices is a decreasing function of the number of informed traders.

Measurement and monitoring of performance practices remain particularly disparate, incomplete and often unsatisfactory within the field of SMEs, due to the insufficiency of their resources and the lack of formal performance management tools. The inadequacy of performance measurement and management systems (PMMS) prevents the owner-manager from producing reliable and accurate financial information and from presenting his situation to various stakeholders, in particular to providers of capital. The objective of this article is therefore to propose a PMMS adapted to SMEs, one that can be used by owner-managers or their consultants to actively manage performance, and also as a tool for communication, negotiation and dialogue with stakeholders. Based on an “enriched DuPont model”, the model presented here focuses on six determinants of value for SME managers. It is decomposed into six successive equations that aim to gradually deepen the understanding of the formation of company performance in connection with the practices and strategic positioning of the firm., Le caractère limité des ressources des PME et le faible recours à des systèmes formels de contrôle sont à l'origine de pratiques incomplètes, partielles et dispersées en matière d'évaluation et de suivi de la performance. Or l'absence ou l'insuffisance de système de mesure et de gestion de la performance (SMGP) obère à la fois la capacité du propriétaire-dirigeant à porter une analyse pertinente sur la situation de son entreprise et sa capacité à échanger et/ou négocier avec les différentes parties prenantes (banques, investisseurs, fournisseurs...). Fort de ce constat, cet article vise à proposer un modèle simple et complet d'évaluation et de signalisation de la performance, adapté à la situation des PME ne disposant pas des moyens de mettre en œuvre de manière systématique une approche plus sophistiquée. Ce modèle peut être utilisé comme un outil d'aide à la décision pour les PME ou leurs conseils de même que comme un outil d'échange et de négociation avec les partenaires externes de l'entreprise. Construit sur la base d'un « modèle DuPont enrichi », le modèle présenté met ainsi l'accent sur six déterminants de la valeur pour les associés de la PME. Il se construit sur la base de 5 équations successives visant à approfondir progressivement la compréhension de la formation de la performance de l'entreprise en lien avec les pratiques et le positionnement stratégiques de la firme.

International audience; L’édition 2007 de la Coupe du Monde de Rugby a été une réussite à bien des égards : audiences des retransmissions télévisées, engouement des femmes et des enfants... Ce moment marque une étape clé dans l’évolution de ce sport car, pour la première fois, il a réuni connaisseurs et néophytes. Ceci a été rendu possible par la transformation de l’événement sportif en expérience émotionnelle. Toutefois, pour que ce phénomène soit durable, il ne doit pas engendrer la perte de l’audience des supporters traditionnels. L’opinion de ces derniers se révèle ainsi essentielle.

The budget is being more and more criticized. Its abandonment is even suggested. This would be the failure of a management tool that was born in the 1930s and that had since a great success. It seems too early to tell whether this criticism will lead to its disappearance. However, we can symmetrically compare the rhetoric that has accompanied its birth with the one developed in order to suggest its abandonment. Interestingly, they are in many ways very similar. In the name of environment uncertainty and managers' empowerment, the budget has alternatively appeared as a solution or a dead-end. We propose an explanation of this phenomenon in the discussion of the paper., Le budget est de plus en plus critiqué. Certains suggèrent même qu'il puisse être abandonné. Cela marquerait l'échec d'un outil apparu dans les années 1930 et qui avait connu un grand succès depuis. Il est encore trop tôt pour savoir si les critiques conduiront à sa disparition. Mais il est déjà suffisamment tôt pour comparer symétriquement les rhétoriques mises en place à sa naissance et celles qui se sont développées pour suggérer sa disparition. Or, certaines de ces rhétoriques sont étrangement similaires. Au nom de la turbulence de l'environnement et de la libération du potentiel créatif des managers, le budget est apparu tantôt comme une solution, tantôt comme une impasse. Nous proposons en conclusion une interprétation de ce phénomène.

This research is concerned with the diffusion of management accounting innovations viewed as a process of actor-network building and translation. The aim is to better understand the nature of accounting change. Using Actor-Network Theory (ANT), we analyze two innovations that have had different fates in France. These innovations are the Georges Perrin method (GPM) and Activity-Based Costing (ABC). We are particularly concerned with the dynamic of actor-networks throughout the diffusion processes of these innovations. We show how problematization, interessement, enrolment and mobilization take many, and often very surprising, forms for diffusion to occur.

[SHS.SOCIO]Humanities and Social Sciences/Sociology - Abstract
Résumé par la revueGérer & Comprendre poursuit ses grands entretiens avec les pionniers de la psychosociologie. Tous se sont demandé, après la Deuxième Guerre mondiale, comment l’homme en était arrivé à ce stade de barbarie. Tous se sont dit qu’il fallait s’intéresser aux relations entre les hommes au sein des groupes, et l’entreprise en constituait un, privilégié. C’était l’après-guerre, les Trente Glorieuses, l’attirance pour la psychologie, la fascination pour les expériences américaines, un terrain entièrement à défricher en France… Il y eut des chemins communs, des conflits, des ruptures, mais tous ont gardé cette jeunesse d’esprit qui fait qu’aujourd’hui encore, ils scrutent les relations humaines dans un monde qui n’a plus rien à voir avec celui des années cinquante.Max Pagès a 81 ans et il se livre spontanément. Très jeune, il va voyager à l’étranger, connaître différents milieux sociaux, et souffrir de la mésentente de ses parents. On comprend mieux son ouverture d’esprit, ses capacités d’adaptation et d’observation, sa quête de réconciliation. Ces qualités, il va les mettre au service d’une recherche permanente : obtenir le changement en agissant sur le système « socio-mental ». La psychologie expérimentale, les expériences américaines sur les groupes, la non-directivité, l’intervention dans de grandes entreprises : tout l’intéresse ! Pragmatique et curieux, il ne cesse de lancer de nouveaux chantiers, avec la conviction que pratique de changement et pratique de recherche sont indissociables. Max Pagès, l’élément incontrôlable de la psychosociologie, est devenu psychothérapeute, et il se demande, aujourd’hui, si la « radicale modération » n’est pas un concept déterminant face aux violences politiques du monde actuel …un nouveau chantier ?

Overconfidence ,Finance ,Irrational markets - Abstract
We analyze a model where irrational and rational informed traders, exchange a risky asset with competitive market makers. irrational traders misperceive the mean of prior information (optimistic/pessimistic bias), the variance of prior information (better/lower than average effect) and the variance of the noise in their private siganal (overconfidence/underconfidence bias). When market makers are rational we obtain results identical to kyle and wang (1997). However if market makers are irrational, we obtain that moderately underconfident traders can outperform rational ones and that irrational market makers can fare better than rational ones. Lastly we find that extreme level of confidence implies high trading volume.

International audience; Comme il a été démontré dans des études antérieures, faire des affaires à l'étranger est plus complexe que transiger uniquement sur les marchés nationaux ou locaux et ce, pour diverses raisons. L'absence de proximité, la langue, la culture, les façons de faire sont autant de facteurs pouvant freiner le développement international des PME ou, du moins, rendre celui-ci moins rapide que le développement national. Les défis de l'exportation sont liés notamment à une bonne connaissance du marché vers lequel on destine nos activités, à la mise en marché d'un produit distinctif qui pourra concurrencer les produits locaux ou nationaux, à l'efficacité de la production etc. Pour relever ces défis et favoriser le succès de l'exportation, on misera ainsi sur l'innovation pour assurer un produit distinctif, la veille concurrentielle pour obtenir une information stratégique, les études de marché sur les besoins de la clientèle, les collaborations pour réduire l'incertitude et accélérer le développement de produits/services appropriés. Dans cette perspective, les technologies de l'information et de la communication (TIC) peuvent servir de supports à l'ensemble de ces activités en accélérant l'obtention d'une information riche et pertinente et en faciliter sa diffusion dans l'entreprise, en favorisant l'innovation et en permettant des collaborations fructueuses entre les divers partenaires. C'est ce que nous proposons de vérifier grâce à l'étude des relations entre les TIC et l'exportation, relation passant par l'innovation, les collaborations, les activités de veille et de recherche d'informations marketing, en prenant également en compte le profil et les objectifs du dirigeant principal de la PME.

This paper shows how informed financial intermediaries can reduce their trading competition by designing optimal incentive compatible contracts for the sale of information. With fund management contracts—indirect sale of information—banks can credibly commit to collaborate and add noise into prices. This is a way to circumvent the Grossman and Stiglitz (1980) paradox: when information is costly, by committing to add noise, the banks can recover the cost of collecting information and enter the market. By contrast, when information is costless, even with a large number of sellers of information entering the market prices are not fully informative.

In this paper, we study a financial market where risk neutral traders are endowed with a signal which is perfectly revealing of the direction (but not the exact amount) of the liquidation value of a normally distributed risky asset. This type of information is known as bullish or bearish. When the signal is positive (negative) the traders buy (sell) the asset. This type of information is different with the type of information which is classically considered in the literature where informed traders are endowed with a perfect or a noisy signal. In this model, since the optimal trading strategy is not linear, the pricing schedule is also a non-linear function of the volumes. The main results are the following i) the price function is a non-linear Sigmo¨ıd-shaped function. ii) A monopolistic bullish-bearish type trader makes nearly thirty six percent of the profits she would have made with a perfect signal in a linear model `a la Kyle (1985). iii) In the presence of competition, the market reveals his private information quicker than in a noisy informed strategic oligopoly. Moreover, liquidity is no longer a monotonic increasing function of the number of competitors.

What are the determinants of accounting and management control innovations diffusion ? This paper attempts to answer such a question by first giving a definition to the concept of managerial innovation. Second it compares the results of the study of the diffusion of three innovations of this kind in France. Several kinds of actors, communication channels and contextual factors are found to impact the diffusion of Activity-Based Costing, budgetary control and the « Georges Perrin » method.; Quels sont les facteurs qui ont une influence sur la diffusion des innovations dans le domaine de la comptabilité et du contrôle de gestion ? Après avoir défini le concept d'innovation managériale, cet article tente de répondre à une telle question en comparant les résultats de l'étude de la diffusion en France de trois innovations de ce type. Différentes catégories d'acteurs, de canaux de communication et variables de contexte ont toutes un impact sur la diffusion de l'ABC, du contrôle budgétaire et de la méthode Georges Perrin.

We analyze the role of liquidity and collection of information in order to measure the speed of revelation of information during the preopening of order-driven markets. We extend Vives (1995) model to the case where risk averse traders receive a new private signal before each round of quotation of the preopening. We show that price discovery takes place at high speed which is consistent with the empirical studies of Biais, Hillion and Spatt (1999).

An informed financial institution can trade on private information and also sell it to clients through a managed fund. To provide an incentive for the informed agent to trade in the interest of her client, the optimal contract requires that she be compensated as an increasing function of the profits of the fund. The optimal contract is also designed to limit the aggressiveness of the sum of the fund's trade and the proprieatary trade. This reduces information revelation and thes leads to greater overall trading profits than if the informed agent only conducted proprietary trades.

National audience; Drawing on the stakeholder salience theory initially developed by Mitchell et al. (1997), this article analyses the influence of various stakeholders on managers’ perception of environmental costs. These costs are no longer seen as a set of expenses driven by technological choices but rather as the result of stakeholders’ influence. The findings of four case studies on asbestos removal show a strong link between perceived stakeholders attributes (power, legitimacy and urgency) and stakeholders influence on environmental costs. This article contributes to Environmental Management Accounting research by proposing a typology of environmental costs based on a dynamic view of stakeholders influence.; En mobilisant la théorie de l’importance des parties prenantes de Mitchell et al. (1997), cet article met en évidence l’influence des parties prenantes sur la perception des managers et donc sur le coût des opérations environnementales. Le coût environnemental n’est alors plus un ensemble de dépenses imposé du fait d’opérations techniques mais le produit de l’influence des parties prenantes. Pour montrer cela, la recherche s’appuie sur quatre études de cas qui explorent différentes opérations de désamiantage. Cet article met en évidence deux apports. Il souligne en premier lieu le lien entre les attributs perçus des parties prenantes (en nombre et en intensité) et l’influence de ces dernières sur les coûts environnementaux. Il contribue ensuite aux travaux sur l’Environmental Management Accounting en proposant une typologie des coûts environnementaux qui intègre les dynamiques induites par l’influence perçue des parties prenantes.

International audience; Information and Communication Technologies (ICTs) in freight transport are more and more used by companies to plan, optimize and monitor their transportation steps. These systems, well known as Transport Management Systems (TMS) were first developed 20 years ago and have recently evolved with Internet of Things and web service technologies. Nevertheless, they do not achieve current sensitive products supply chain objectives and are facing with several issues due to a more and more complex logistic environment. The French Blood Establishment case is used to put forward this lacks. Considering the upcoming logistics trends and the existing TMS failures we propose a new approach to monitor freight transportation, considering on one part smart containers and on the other part load displacement capacities.

International audience; Many authors have highlighted the gap between the supply side and the demand side of the order fulfilment process. Generally, the latter tends primarily to be “agile” by maximising responsiveness and flexibility while the former tends to be “lean” by maximising efficiency. However, the most fundamental trade-offs in supply chain management are between these two properties. This is the “leagile” objective. In stock-out situation, the delivery options that would minimize the customers’ dissatisfaction while reconciling the conflicting objectives of the different actors of the supply network must be defined. Today, no particular method seems to allow managing bulk within this leagile ambition. This paper proposes a non-sequential Advanced Available-to-promise model to tackle this question. The model is applied to a numerical example and the results obtained are used to illustrate the most representative delivery strategies.

This paper considers an integrated routing and scheduling problem where the routing part takes into account routing costs and tardiness penalties and the scheduling part is modelled by a permutation flow shop with inventory costs. We assume that each batch is served by a dedicated vehicle, and that the number of batches and their compositions (the number of jobs and the parameters of those jobs) are known in advance. The problem is to determine the starting times of the jobs on each machine in the flow shop, the departure dates of the batches and their delivery route, such that the total cost (sum of inventory, routing and penalty costs) is minimised. A two-step approach is proposed. In a first step, the optimal delivery routes for each batch and each possible departure date are calculated. This is possible as determining the min cost route for a particular delivery batch and a particular departure date is easy. In a second step, we use the delivery cost function for each batch, depending on the departure date, from the first step, to find a schedule that minimises the total cost. Computational experiments are performed on randomly generated instances.

International audience; Si l’impact des sciences de gestion est surtout attendu dans le domaine du management des entreprises, notre communication s’intéresse à leur impact sur les politiques publiques, notamment celles qui concernent les éco-systèmes d’entreprises. Elle s’appuie sur le cas de la « stratégie logistique nationale » qui est en cours d’élaboration. Après avoir retracé la genèse de cette stratégie nationale, la communication montre comment et à quel titre des enseignants-chercheurs en sciences de gestion ont contribué à son émergence avant de participer à son processus d’élaboration. L’analyse de la nature de leur contribution et de l’évolution de leur rôle dans ce processus invite à formuler des questions sur ce type de recherche et, également, sur sa reconnaissance par les institutions académiques.

- Abstract
Network analysis has found widespread utility in many research areas. However, assessing the statistical significance of observed relationships within networks remains a complex challenge. Traditional node permutation tests are often insufficient in capturing the effect of changing network topology by creating reliable null distributions. We propose two randomization alternatives to address this gap: random rewiring and controlled rewiring. These methods incorporate changes in the network topology through edge swaps. However, controlled rewiring allows for more nuanced alterations of the original network than random rewiring. In this sense, this paper introduces a novel evaluation tool, the Expanded Quadratic Assignment Procedure (EQAP), designed to calculate a specific p-value and interpret statistical tests with enhanced precision. The combination of EQAP and controlled rewiring provides a robust network comparison and statistical analysis framework. The methodology is exemplified through two real-world examples: the analysis of an organizational network structure, illustrated by the Enron-Email dataset, and a social network case, represented by the UK Faculty friendship network. The utility of these statistical tests is underscored by their capacity to safeguard researchers against Type I errors when exploring network metrics dependent on intricate topologies., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Salbanya et al.

- Abstract
Climate change is currently one of humanity's greatest threats. To help scholars understand the psychology of climate change, we conducted an online quasi-experimental survey on 59,508 participants from 63 countries (collected between July 2022 and July 2023). In a between-subjects design, we tested 11 interventions designed to promote climate change mitigation across four outcomes: climate change belief, support for climate policies, willingness to share information on social media, and performance on an effortful pro-environmental behavioural task. Participants also reported their demographic information (e.g., age, gender) and several other independent variables (e.g., political orientation, perceptions about the scientific consensus). In the no-intervention control group, we also measured important additional variables, such as environmentalist identity and trust in climate science. We report the collaboration procedure, study design, raw and cleaned data, all survey materials, relevant analysis scripts, and data visualisations. This dataset can be used to further the understanding of psychological, demographic, and national-level factors related to individual-level climate action and how these differ across countries., (© 2024.

- Abstract
Undercover videos have become a popular tool among NGOs to influence public opinion and generate engagement for the NGO's cause. These videos are seen as a powerful and cost-effective way of bringing about social change, as they provide first-hand evidence and generate a strong emotional response among those who see them. In this paper, we empirically assess the impact of undercover videos on support for the cause. We in addition analyze whether the increased engagement among viewers is driven by the negative emotional reactions produced by the video. To do so, we design an online experiment that enables us to estimate both the total and emotion-mediated treatment effects on engagement by randomly exposing participants to an undercover video (of animal abuse) and randomly introducing a cooling-off period. Using a representative sample of the French population (N=3,310), we find that the video successfully increases actions in favor of animals (i.e., donations to NGOs and petitions), but we fail to prove that this effect is due to the presence of primary emotions induced by the video. Last, we investigate whether activists correctly anticipate their undercover videos' (emotional) impact via a prediction study involving activists (exploratory analysis).

- Abstract
This paper examines quantitative predictors of team performance in Massively Multiplayer Online Games (MMOGs) based on team management literature. Analyzing data from more than 140,000 squad-mode matches involving over 500,000 players, we replicate and extend existing research by confirming a curvilinear association between behavioral interdependence and team performance and introduce the moderating effect of experience. For less experienced teams, behavioral interdependence follows an inverted U-shaped pattern showing that excessive collaboration may be counterproductive. However, this is not the case for experienced teams, where the relationship is fairly linear. Additionally, we observe that riskier teams tend to perform worse. Moreover, our research also highlights the potential of e-sports data in advancing behavioral science and management research. The digital nature of e-sports datasets, characterized by size and granularity, mitigates concerns related to reproducibility, replicability, and generalizability in social science research, offering a cost-effective platform for scholars with diverse backgrounds., (© 2024.

- Abstract
Effectively reducing climate change requires marked, global behavior change. However, it is unclear which strategies are most likely to motivate people to change their climate beliefs and behaviors. Here, we tested 11 expert-crowdsourced interventions on four climate mitigation outcomes: beliefs, policy support, information sharing intention, and an effortful tree-planting behavioral task. Across 59,440 participants from 63 countries, the interventions' effectiveness was small, largely limited to nonclimate skeptics, and differed across outcomes: Beliefs were strengthened mostly by decreasing psychological distance (by 2.3%), policy support by writing a letter to a future-generation member (2.6%), information sharing by negative emotion induction (12.1%), and no intervention increased the more effortful behavior-several interventions even reduced tree planting. Last, the effects of each intervention differed depending on people's initial climate beliefs. These findings suggest that the impact of behavioral climate interventions varies across audiences and target behaviors.

- Abstract
The COVID-19 pandemic has affected all domains of human life, including the economic and social fabric of societies. One of the central strategies for managing public health throughout the pandemic has been through persuasive messaging and collective behaviour change. To help scholars better understand the social and moral psychology behind public health behaviour, we present a dataset comprising of 51,404 individuals from 69 countries. This dataset was collected for the International Collaboration on Social & Moral Psychology of COVID-19 project (ICSMP COVID-19). This social science survey invited participants around the world to complete a series of moral and psychological measures and public health attitudes about COVID-19 during an early phase of the COVID-19 pandemic (between April and June 2020). The survey included seven broad categories of questions: COVID-19 beliefs and compliance behaviours; identity and social attitudes; ideology; health and well-being; moral beliefs and motivation; personality traits; and demographic variables. We report both raw and cleaned data, along with all survey materials, data visualisations, and psychometric evaluations of key variables., (© 2023. The Author(s).)

- Abstract
Psychological traits display substantial variation worldwide. These psychological variations could be explained by the intensity of kinship ties which, we hypothesize, depends on the reception of innovations that gradually complexified family organizations. These innovations originated from several centers across the world that also spread other crucial novelties such as agriculture. Less exposed to these family innovations, areas far from centers of innovation should exhibit lower kinship intensity. Indeed, we show that distance to innovation centers is strongly associated with kinship intensity. This distance is also associated with psychological traits especially outside Western Europe in which exposure to the Church seems to play an additional role., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 le Bris, Gay.

- Abstract
Single people are more likely to die from COVID-19. Here we study whether this higher death rate could be partly explained by differences in compliance with protective health measures against COVID-19 between single and married people, and the drivers of this marital compliance gap. Data collected from 46,450 respondents in 67 countries reveal that married people are more likely to comply with protective measures than single people. This marital gap in compliance is higher for men (approximately 5%) than for women (approximately 2%). These results are robust across a large range of countries and independent of country level differences with respect to culture, values or infection rates. Prosocial characteristics linked to morality and social belonging explain more than 38% of the marital gap, while individual risk perceptions play a minor role. These findings help explain single people's and particularly single men's greater vulnerability to COVID-19, which in turn can be leveraged to improve the effectiveness of international public policy campaigns aimed at promoting protective health measures., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2022 Elsevier B.V.

- Abstract
Background: Telerehabilitation (TR) interventions are receiving increasing attention. They have been evaluated in various scientific areas through systematic reviews. However, there is a lack of data on how to standardize assessment and report on their domains to guide researchers across studies and bring together the best evidence to assess TR for chronic diseases., Aims and Objectives: The aim of this study was to identify domains of assessment in TR and to qualitatively and quantitatively analyze how and when they are examined to gain an overview of assessment in chronic disease., Methods: A scoping meta-review was carried out on 9 databases and gray literature from 2009 to 2019. The keyword search strategy was based on "telerehabilitation", "evaluation", "chronic disease" and their synonyms. All articles were subjected to qualitative analysis using the Health Technology Assessment (HTA) Core Model prior to further analysis and narrative synthesis., Results: Among the 7412 identified articles, 80 studies met the inclusion criteria and addressed at least one of the noncommunicable diseases (NCD) categories of cardiovascular disease (cardiovascular accidents), cancer, chronic respiratory disease, diabetes, and obesity. Regarding the domains of assessment, the most frequently occurring were "social aspect" (n = 63, 79%) (e.g., effects on behavioral changes) and "clinical efficacy" (n = 53, 66%), and the least frequently occurring was "safety aspects" (n = 2, 3%). We also identified the phases of TR in which the assessment was conducted and found that it most commonly occurred in the pilot study and randomized trial phases and least commonly occurred in the design, pretest, and post-implementation phases., Conclusions: Through the HTA model, this scoping meta-review highlighted 10 assessment domains which have not been studied with the same degree of interest in the recent literature. We showed that each of these assessment domains could appear at different phases of TR development and proposed a new cross-disciplinary and comprehensive method for assessing TR interventions. Future studies will benefit from approaches that leverage the best evidence regarding the assessment of TR, and it will be interesting to extend this assessment framework to other chronic diseases., (© 2022.

- Abstract
Background: Delays in the diagnosis of neurodevelopmental disorders (NDDs) in toddlers and postnatal depression (PND) in mothers are major public health issues. In both cases, early intervention is crucial., Objective: We aimed to assess if a mobile app named Malo can reduce delay in the recognition of NDD and PND., Methods: We performed an observational, cross-sectional, data-based study in a population of young parents with a minimum of 1 child under 3 years of age at the time of inclusion and using Malo on a regular basis. We included the first 4000 users matching the criteria and agreeing to participate between November 11, 2021, and January 14, 2022. Parents received monthly questionnaires via the app, assessing skills on sociability, hearing, vision, motricity, language of their infants, and possible autism spectrum disorder. Mothers were also requested to answer regular questionnaires regarding PND, from 4-28 weeks after childbirth. When any patient-reported outcomes matched predefined criteria, an in-app notification was sent to the user, recommending the booking of an appointment with their family physician or pediatrician. The main outcomes were the median age of the infant at the time of notification for possible NDD and the median time of PND notifications after childbirth. One secondary outcome was the relevance of the NDD notification for a consultation as assessed by the physicians., Results: Among 4242 children assessed by 5309 questionnaires, 613 (14.5%) had at least 1 disorder requiring a consultation. The median age of notification for possible autism spectrum, vision, audition, socialization, language, or motor disorders was 11, 9, 17, 12, 22, and 4 months, respectively. The sensitivity of the alert notifications of suspected NDDs as assessed by the physicians was 100%, and the specificity was 73.5%. Among 907 mothers who completed a PND questionnaire, highly probable PND was detected in 151 (16.6%) mothers, and the median time of detection was 8-12 weeks., Conclusions: The algorithm-based alert suggesting NDD was highly sensitive with good specificity as assessed by real-life practitioners. The app was also efficient in the early detection of PND. Our results suggest that the regular use of this multidomain familial smartphone app would permit the early detection of NDD and PND., Trial Registration: ClinicalTrials.gov NCT04958174; https://clinicaltrials.gov/ct2/show/NCT04958174., (©Fabrice Denis, Laura Maurier, Kevin Carillo, Roxana Ologeanu-Taddei, Anne-Lise Septans, Agnes Gepner, Florian Le Goff, Madhu Desbois, Baptiste Demurger, Denise Silber, Jean-David Zeitoun, Guedalia Peretz Assuied, Olivier Bonnot.

292. Blockchain technology adoption for managing risks in operations and supply chain management: evidence from the UK.

- Abstract
The impact of blockchain technology (BCT) implementation on the accuracy, reliability, visibility, incorruptibility, and timeliness of supply-chain processes and transactions, makes it attractive to improve the robustness, transparency, accountability and decision-making in risk management. Therefore, the emerging BCT can present an invaluable opportunity for the organisations in need of preparing for and responding to uncertain and complex instances. The adoption of BCT in the operations and supply chain management (OSCM) literature remains scarcely investigated, especially in the context of managing risks in emergency situations such as crises, disasters, and pandemics, which are characterised by volatility, uncertainty, complexity and ambiguity (VUCA) in the business environment. This article will contribute to the OSCM literature by developing a conceptual model that will examine the causal relationships between VUCA business environment, constructs derived from technology acceptance model (TAM), resilience and behavioural intention of the operations managers to adopt BCT for risk management. The model was tested by gathering responses from 116 operations managers in the UK (during COVID-19 pandemic) through structural equation modelling. Findings from the analysis suggest that understanding the benefits of BCT, involvement in resilient organisational practices and user-friendly implementation of the technology will have a significant and positive influence on the intention to adopt BCT for risk management in the OSCM context. Building upon these findings, we have proposed a BCT decision framework to assess the feasibility and suitability of adopting BCT in each context (such as risk management), which will have strategic implications for operations managers and the OSCM community., (© The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2022.)

- Abstract
The impact of the social media (SM) has been seen on the one hand as the cause of large exacerbation of negative messages, responsible for massively harmful societal phenomenon against democracies. On the other hand, recent studies have begun to look at how these online channels were able to provide a new impulse in human communication. The novelty of our work resides on analysing several axes of polarizations related to different societal topics. We believe our approach to reflect a more complex society, differing from the recent literature, which has considered a unique left-right dichotomic cleavage. Our methodology consists of extracting topics from the priority themes of the SM debate, using BERT language processing techniques and TF-IDF model. Our results show situation of social media interactions in a multidimensional space does exist. We highlight how social media behaviours, polarization and cross-fertilization differ as upon concrete topics. We argue therefore the 'mega-identity partisanship' which differentiate US online users in two different spaces cannot be extended for the rest of countries taking as first evidence the case of Spain. Further research should extend our conclusions for a possible generalization., Competing Interests: Conflict of interestAuthors claim they have no financial or non-financial interests that are directly or indirectly related to the work submitted for publication., (© The Author(s) 2022.)

- Abstract
Italy has one of the highest levels of childhood overweight and obesity in Europe. Therefore, preventing children from becoming overweight is a major public health challenge. Here, we used a mixed-method research approach - including a quasi-experimental design and three surveys - to create a formative evaluation of a social marketing campaign on healthy nutrition and lifestyle in Italian primary school children. The social marketing campaign was organized around the 4 Ps of the marketing mix (product: the educational activities; place: the involved schools and supermarkets; promotion: the in-person and technology-based communication; and price: hours spent by the targeted children in fulfilling the educational activities). The campaign involved primary-school children across four Italian cities. The findings suggest that social marketing education campaigns can be effective tools to improve children's knowledge about healthy food and lifestyle, reduce their sedentary behavior, and increase their consumption of healthy food. Also, increasing children's acceptance of healthful nourishment is a valuable tool to improve the dietary habits of the entire family. With relation to the educational program assessment method, this study can inform societal interventions especially those involving children through the integration of different qualitative and quantitative research methods, which collect data from different subjects and perspectives., (Copyright © 2021.

295. Infection vulnerability stratification risk modelling of COVID-19 data: a deterministic SEIR epidemic model analysis.

- Abstract
Basic Susceptible-Exposed-Infectious-Removed (SEIR) models of COVID-19 dynamics tend to be excessively pessimistic due to high basic reproduction values, which result in overestimations of cases of infection and death. We propose an extended SEIR model and daily data of COVID-19 cases in the U.S. and the seven largest European countries to forecast possible pandemic dynamics by investigating the effects of infection vulnerability stratification and measures on preventing the spread of infection. We assume that (i) the number of cases would be underestimated at the beginning of a new virus pandemic due to the lack of effective diagnostic methods and (ii) people more susceptible to infection are more likely to become infected; whereas during the later stages, the chances of infection among others will be reduced, thereby potentially leading to pandemic cessation. Based on infection vulnerability stratification, we demonstrate effects brought by the fraction of infected persons in the population at the start of pandemic deceleration on the cumulative fraction of the infected population. We interestingly show that moderate and long-lasting preventive measures are more effective than more rigid measures, which tend to be eventually loosened or abandoned due to economic losses, delay the peak of infection and fail to reduce the total number of cases. Our calculations relate the pandemic's second wave to high seasonal fluctuations and a low vulnerability stratification coefficient. Our characterisation of basic reproduction dynamics indicates that second wave of the pandemic is likely to first occur in Germany, Spain, France, and Italy, and a second wave is also possible in the U.K. and the U.S. Our findings show that even if the total elimination of the virus is impossible, the total number of infected people can be reduced during the deceleration stage., (© The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2021.)

- Abstract
We introduce a new information and communication technology (ICT) cloud-based architecture for Global Navigation Satellite System (GNSS) high-accuracy solutions, offering also a commercial overview of GNSS downstream market to show how the developed innovation is thought to fit in the real context. The designed architecture is featured by dynamic scalability, increased integrity, and greater agility of the ICT system. The novelty of the solution developed is a customized ICT architecture, obtained through unique and privileged access to user communities in the frame of the H2020 project TREASURE, allowing the development of a solution entirely driven by user needs. The economic outlook of GNSS downstream markets evolution highlights how the technology proposed effectively matches the evolving business environment, specifically in regard to the increasing need for flexibility and competitive advantage deriving from services. The simultaneous adoption of the technical and commercial perspective is meant to offer interesting findings to both the scientific community and GNSS industry, creating synergies previously unexplored.

- Abstract
Inspired by the natural-resource-based view (NRBV) theory, we attempt to shed light on a controversy which has been persistent over the last decade, concerning the relationship between corporate environmental performance (CEP) and corporate financial performance (CFP). Using the 'too-much-of-a-good-thing' (TMGT) concept, which suggests that "too much can be worse than too little," we link mixed results and consider the roles of advanced eco-learning and contingency factors in influencing the CEP-CFP relationship. Based on a sample composed of ISO 14001 certified companies in Indonesia, and analyzing the data using consistent Partial Least Squares (PLSc), we found that: the CEP-CFP relationship follows an inverted U-shape; advanced eco-learning is a significant predictor of the CEP-CFP relationship, meaning that organizations able to develop higher eco-learning capability will be better able to identify the ideal boundaries of investment in environmental performance without reducing their financial performance; and that contingency factors such as environmental strategy and firm size have a significant role in influencing the CEP-CFP relationship. The study's limitations, implications for practitioners and a future research agenda are also detailed., (Copyright © 2018 Elsevier Ltd. All rights reserved.)

300. Smoke screen? The globalization of production, transnational lobbying and the international political economy of plain tobacco packaging.

Curran L and Eckhardt J
- Abstract
In 2012 Australia became the first country in the world to introduce plain tobacco packaging in an effort to reduce tobacco consumption. This move was vehemently opposed by the tobacco industry, which challenged it on several levels: nationally, bilaterally and multilaterally at the World Trade Organization (WTO). The political behavior of the tobacco companies in this case is puzzling both in terms of scale, operating at multiple levels at the same time and in terms of the countries mobilized in their defence. WTO litigation is typically the result of Multi National Enterprises (MNEs) lobbying their own government, but here third countries were mobilized. Lobbying in third country contexts, with the objective of accessing multilateral dispute settlement systems, has been little studied. We thus know very little about the driving factors behind such activities, how target governments are selected and what lobbying strategies are used. This paper draws on emerging research on transnational lobbying and a case study of the PP case to explore these issues in detail and, by doing so, aims to further our theoretical understanding of the political economy of international trade in the context of increasing regime complexity and globalization of production.
