Boutique Asset Managers: Protect Your Business and Reputation Against RisksFIS
How can boutique asset managers defend themselves against the current, dominant risks to their business? How can boutiques asset managers overcome compliance and operational hurdles?
Boutiques must demonstrate operational excellence and compliance to encourage investors, without incurring excessive cost or complexity. They need mastery over data and automation of the front office. Early adopters who develop a strategic approach to handling change, reduce the pressure associated with regulation.
In a recent survey by TABB Group, half of all participants indicated they are looking to technology providers to assist more with compliance obligations. A recent survey by Chartis found data management gaining in importance with 91 percent of respondents rated data quality as crucial.
How can you streamline operations to reduce costs, ensure good data management for greater insight, and enhance risk management to meet investor expectations?

This document appears to be from a discussion about what skills and knowledge teachers need to be considered technologically proficient in 2013. It includes questions about whether it is acceptable for teachers to be technologically illiterate and what interesting educational technology projects participants would show teachers and parents. The discussion emphasizes the importance of reflection, critical thinking, and discernment when evaluating new technologies rather than just focusing on the technologies themselves. It also references comments made by others on the topics of technologically illiterate teachers and finding good primary/elementary education technology projects.

This document discusses social media usage and trends related to wine consumption in the United States. It finds that over half of Americans participate in online conversations about wine, and nearly half seek opinions from wine bloggers. Sparkling wine consumption is growing twice as fast as still wines, with Prosecco imports increasing the most. The document also analyzes which topics and communities on American websites most discuss sparkling wines. Champagne is most prominently featured on social media to showcase brands and luxury lifestyles.

Arabian Cement Company (ARCC) has been in a clear downtrend for the past 20 months, declining from 19.00 in February 2015 to 4.25. Last week, the stock closed barely changed from its opening price, indicating an equilibrium between bulls and bears. Technical indicators like the Price Oscillator, RSI, and Stochastic Oscillator have reached oversold levels. While the downtrend remains intact, signs of weakness in the bears and positive divergences in indicators suggest an upward correction may occur in the coming weeks. The report recommends gradual accumulation below 4.00, with a target price of 5.70-6.00.
The document describes 4 basic communication styles - passive, aggressive, passive-aggressive, and assertive. Passive communicators avoid expressing feelings and needs, leading to low self-esteem. Aggressive communicators violate others' rights to advocate for themselves. Passive-aggressive communicators feel powerless and sabotage others indirectly. Assertive communicators clearly state feelings and needs without violating others, building high self-esteem and healthy relationships.
Burnout is a state of emotional, mental, and physical exhaustion caused by prolonged and excessive stress. It can develop quickly over 6 months on average as a result of poor leadership, lack of support from an organization, work overload, and other factors. Recovery from burnout is a slow process, taking an average of 2 years, as the person must physically and psychologically remove themselves from the stressors, gain self-knowledge and acceptance, and revise their relationship with their work. The difficulty in recovering stems from personality traits, physical symptoms of fatigue and illness, and unsupportive organizational cultures and policies. Future leaders are advised to remember the humanity of their workforce and prioritize employee well-being.

This document discusses the work of CHEN, a patient fertility association in Israel, and its role in influencing fertility policy. It notes that over 150,000 frozen embryos in Israel are currently "leftovers" after 5 years in storage. CHEN has decided to promote a new law that would allow parents to donate their remaining IVF embryos to other patients after 5 years, rather than having them discarded. The organization is working to convince the Ministry of Health and Knesset to pass this law, and plans an accompanying public campaign aimed at clinics and patients. CHEN hopes this law will find a solution for the stored embryos and help patients in need of donation.

This document discusses different types of accounting vouchers used to record business transactions. It explains that a transaction voucher contains one debit and one credit and is used for simple transactions. A compound voucher contains multiple debits or credits and is used for more complex transactions. It also describes debit vouchers, credit vouchers, and complex/journal vouchers which are used for transactions with multiple debits and credits. The vouchers contain details of the transaction such as date, accounts, amounts, and approvals. Vouchers must be properly prepared, approved, and preserved for audit purposes.
The document discusses five communication styles: assertive, aggressive, passive-aggressive, submissive, and manipulative. It provides descriptions of each style's behavioral characteristics, non-verbal behaviors, and how the receiving person typically feels. Understanding these styles helps one react effectively to different personality types and recognize when one's own style could be improved. The assertive style, involving confidence and respect for others, is generally considered the healthiest approach.

Sur un exemple très concret d’audit d’éco-conception de l’outil de bilan carbone C’Bilan développé par ICDC (Caisse des dépôts et consignations) nous allons expliquer en quoi l’ACV (analyse de cycle de vie) a été déterminante pour identifier les pistes d’actions pour réduire jusqu'à 82% de l’empreinte environnementale du service.

Compte-rendu :
L'IA connaît une croissance rapide et son intégration dans le domaine éducatif soulève de nombreuses questions. Aujourd'hui, nous explorerons comment les étudiants utilisent l'IA, les perceptions des enseignants à ce sujet, et les mesures possibles pour encadrer ces usages.
Constat Actuel
L'IA est de plus en plus présente dans notre quotidien, y compris dans l'éducation. Certaines universités, comme Science Po en janvier 2023, ont interdit l'utilisation de l'IA, tandis que d'autres, comme l'Université de Prague, la considèrent comme du plagiat. Cette diversité de positions souligne la nécessité urgente d'une réponse institutionnelle pour encadrer ces usages et prévenir les risques de triche et de plagiat.
Enquête Nationale
Pour mieux comprendre ces dynamiques, une enquête nationale intitulée "L'IA dans l'enseignement" a été réalisée. Les auteurs de cette enquête sont Le Sphynx (sondage) et Compilatio (fraude académique). Elle a été diffusée dans les universités de Lyon et d'Aix-Marseille entre le 21 juin et le 15 août 2023, touchant 1242 enseignants et 4443 étudiants. Les questionnaires, conçus pour étudier les usages de l'IA et les représentations de ces usages, abordaient des thèmes comme les craintes, les opportunités et l'acceptabilité.
Résultats de l'Enquête
Les résultats montrent que 55 % des étudiants utilisent l'IA de manière occasionnelle ou fréquente, contre 34 % des enseignants. Cependant, 88 % des enseignants pensent que leurs étudiants utilisent l'IA, ce qui pourrait indiquer une surestimation des usages. Les usages identifiés incluent la recherche d'informations et la rédaction de textes, bien que ces réponses ne puissent pas être cumulées dans les choix proposés.
Analyse Critique
Une analyse plus approfondie révèle que les enseignants peinent à percevoir les bénéfices de l'IA pour l'apprentissage, contrairement aux étudiants. La question de savoir si l'IA améliore les notes sans développer les compétences reste débattue. Est-ce un dopage académique ou une opportunité pour un apprentissage plus efficace ?
Acceptabilité et Éthique
L'enquête révèle que beaucoup d'étudiants jugent acceptable d'utiliser l'IA pour rédiger leurs devoirs, et même un quart des enseignants partagent cet avis. Cela pose des questions éthiques cruciales : copier-coller est-il tricher ? Utiliser l'IA sous supervision ou pour des traductions est-il acceptable ? La réponse n'est pas simple et nécessite un débat ouvert.
Propositions et Solutions
Pour encadrer ces usages, plusieurs solutions sont proposées. Plutôt que d'interdire l'IA, il est suggéré de fixer des règles pour une utilisation responsable. Des innovations pédagogiques peuvent également être explorées, comme la création de situations de concurrence professionnelle ou l'utilisation de détecteurs d'IA.
Conclusion
En conclusion, bien que l'étude présente des limites, elle souligne un besoin urgent de régulation. Une charte institutionnelle pourrait fournir un cadre pour une utilisation éthique.
Ouvrez la porte ou prenez un mur (Agile Tour Genève 2024)Laurent Speyser
(Conférence dessinée)
Vous êtes certainement à l’origine, ou impliqué, dans un changement au sein de votre organisation. Et peut être que cela ne se passe pas aussi bien qu’attendu…
Depuis plusieurs années, je fais régulièrement le constat de l’échec de l’adoption de l’Agilité, et plus globalement de grands changements, dans les organisations. Je vais tenter de vous expliquer pourquoi ils suscitent peu d'adhésion, peu d’engagement, et ils ne tiennent pas dans le temps.
Heureusement, il existe un autre chemin. Pour l'emprunter il s'agira de cultiver l'invitation, l'intelligence collective , la mécanique des jeux, les rites de passages, .... afin que l'agilité prenne racine.
Vous repartirez de cette conférence en ayant pris du recul sur le changement tel qu‘il est généralement opéré aujourd’hui, et en ayant découvert (ou redécouvert) le seul guide valable à suivre, à mon sens, pour un changement authentique, durable, et respectueux des individus! Et en bonus, 2 ou 3 trucs pratiques!
MongoDB in a scale-up: how to get away from a monolithic hell — MongoDB Paris...Horgix
This is the slide deck of a talk by Alexis "Horgix" Chotard and Laurentiu Capatina presented at the MongoDB Paris User Group in June 2024 about the feedback on how PayFit move away from a monolithic hell of a self-hosted MongoDB cluster to managed alternatives. Pitch below.
March 15, 2023, 6:59 AM: a MongoDB cluster collapses. Tough luck, this cluster contains 95% of user data and is absolutely vital for even minimal operation of our application. To worsen matters, this cluster is 7 years behind on versions, is not scalable, and barely observable. Furthermore, even the data model would quickly raise eyebrows: applications communicating with each other by reading/writing in the same MongoDB documents, documents reaching the maximum limit of 16MiB with hundreds of levels of nesting, and so forth. The incident will last several days and result in the loss of many users. We've seen better scenarios.
Let's explore how PayFit found itself in this hellish situation and, more importantly, how we managed to overcome it!
On the agenda: technical stabilization, untangling data models, breaking apart a Single Point of Failure (SPOF) into several elements with a more restricted blast radius, transitioning to managed services, improving internal accesses, regaining control over risky operations, and ultimately, approaching a technical migration when it impacts all development teams.
