#Forrester_Research Platforms Are The Foundation For New Value Creation

While a lot has been written about consumer-facing platforms like Facebook and Uber, the platform impact on business-to-business relationships has not been as extensively investigated. However, these “business platform models” are transforming the way how traditional businesses create value. Business platforms will reorganize a wide variety of markets, work arrangements, and ultimately value creation and capture.

Business platforms push productivity improvements beyond automation activities. The real value creation now comes from analyzing data. These platform dynamics force every business to rethink its approach to innovation, marketing, sales, product development, delivery, and customer engagement. Business and technology leaders need to prepare to platform dynamics for several reasons:

  • Platforms change customer behavior and how businesses interact with customers. Business platforms will trigger radical changes to how we work, engage with customers, create value, and compete for the resulting profits. These business platforms offer companies fast access to scalable expertise at transparent cost and drive the much needed agility to quickly adjust customer experiences to changing requirements.

Introduction to LCA : Latent Class Analysis #Marketingthema

Latent class analysis (LCA) identifies unobservable subgroups within a population. We work to expand LCA models to allow scientists to better understand the impact of exposure to patterns of multiple risks, as well as the antecedents and consequences of complex behaviors, so that interventions can be tailored to target the subgroups that will benefit most.

The death of the theorist and the emergence of data and algorithms in digital social research

Computer software and data-processing algorithms are becoming an everyday part of Higher Education. How might this be affecting research in the social sciences and the formation of the professional identities of academics? Ben Williamson argues that these are important challenges for social science researchers in HE, asking us to consider how digital devices and infrastructures might be shaping our professional practices, knowledge production, and theories of the world.

Computer code, software and algorithms have sunk deep into what Nigel Thrift has described as the “technological unconscious” of our contemporary “lifeworld,” and are fast becoming part of the everyday backdrop to Higher Education. Academic research across the natural, human and social sciences is increasingly mediated and augmented by computer coded technologies. This is perhaps most obvious in the natural sciences and in developments such as the vast human genome database. As Geoffrey Bowker has argued, such databases are increasingly viewed as a challenge to the idea of the scientific paper (with its theoretical framework, hypothesis and long-form argumentation) as the “end result” of science:

Le meilleur des mondes : ce que le roman peut nous apprendre sur la puissance du conditionnement mental et la société de consommation! Huxley a vu juste!

 


C’est probablement l’un des meilleurs romans et films que j’ai vu depuis Matrix. Aldous Huxley a écrit Brave New World en 1932, il y a presque quatre-vingts ans, mais le livre se lit comme s’il aurait pu être écrit hier. Ce qui est particulièrement intéressant pour moi, c’est la façon dont Huxley a pu prévoir plusieurs innovations actuelles, telles que le suivi par satellite, les écrans interactifs, les injonctions de consommation, la superficialité de la société, le génie génétique, la promiscuité sexuelle partout, etc. Huxley est bien plus important que Orwell, qui s’est inspiré 10 ans plus tard par ses œuvres! Si Orwell présente la société totalitaire en 1984 par le biais de la censure et de la manipulation de mots et d’informations, Huxley montre de manière beaucoup plus subtile comment la société de consommation et la recherche de l’hédonisme créent une société amoureuse de sa propre servitude.

An Introduction to Jeffreys’s Bayes Factors With the SumStats Module in JASP: Part 1 | Bayes methods from: jasp-stats.org

In this blog post we elaborate on the ideas behind Harold Jeffreys’s Bayes factor and illustrate this test with the Summary Statistics module in JASP.

In a previous blog post we discussed the estimation problem, where the goal was to infer, from the observed data, the magnitude of the population effect. Before studying the size of an effect, however, we arguably first need to investigate whether an effect actually exists. Here we address the existence problem with a hypothesis test and we emphasize the difference between testing and estimation.

The outline of this blog post is as follows: Firstly, we discuss a hypothesis proposed in a recent study relating fungal infections to Alzheimer’s disease. This hypothesis is then operationalized within a statistical model, and we discuss Bayesian model learning in general, before we return to the Alzheimer’s example. This is followed by a comparison of the Bayes factor to other methods of inference, and the blog post concludes with a short summary.

Effondrement de la civilisation (Pic pétrolier, Réchauffement climatique, énergie) #Collapsologie

Cette vidéo a pour but de faire découvrir et expliquer la forte possibilité d’un effondrement de notre civilisation à travers des extraits d’interviews d’experts parlant de grands phénomènes qui participent à cet effondrement. Que cela soit la pénurie de ressources, le changement climatique, le pic pétrolier, la non résilience de notre système financier et beaucoup d’autres phénomènes, il est important de comprendre que tout cela est interconnecté et « favorisera » l’effondrement de notre civilisation thermo-industrielle.

Corrupt Research: The Case for Reconceptualizing Empirical Management and Social Science

Hubbard, R. (2015). Corrupt research: The case for reconceptualizing empirical management and social science. Sage Publications.

I’m reading this great book written by Hubbard a great marketing scholar about the current NHST paradigm in research. The author is defending the idea that we are producing « unreliable science » that is absolutely useless! Summarizes lots of evidence that the pervasive use of NHTS (Null Hypothesis statistical testing) is bad practice. The author suggests another model and defends the same ideas of Geoff Cumming about the new statistics based on confidence intervals instead of p values and open science in his book of 2013 Understanding the new statistics: Effect sizes, confidence intervals, and meta-analysis. Routledge.

The book of Hubbard is a major contribution and alert toward the research community about the actual research paradigm that we can qualify as an « Ostrich politic » where publishers and academics waste ressources (time, money, effort) for advancing their careers through « fake or misleading » publications instead of seeking to change the system and to seek the truth! this is the noble objective of science, not citations, or rankings! We need a cummulative system that allows replication and integration of findings.

As expected no one is a prophet is his own country, like any established community, gatekeepers don’t like people who go against the mainstream doxa, and this book received little interest while it’s a major contribution and very urgent issue in academic research. Few are those who have the courage and honesty to say it loudly like the excellent positions taken by Barnett , or Kuntz , or Cumming ! but history will give credit to those who stood with a backbone for the truth.

I follow many groups in various disciplines, and this issue will be the TRUE CHALLENGE for the next years if we want to tackle the credibility of scientific research!

« Politique de l’autruche » : un court-métrage brillant en allégorie de notre société

 

« Sous la forme d’une comparaison subtile, le réalisateur libanais Mohammad HouHou interroge, dans son dernier court-métrage intitulé La politique de l’autruche, la façon dont nos sociétés se construisent autour de croyances erronées et pourtant particulièrement difficiles à remettre en cause. Il nous invite à cesser de nous voiler la face pour interroger nos convictions profondes à la lumière de la réalité. »

#Hoax: three scholars wrote 20 fake papers using fashionable jargon and what it reveals about academia! #Publish&Perish

James A. Lindsay, Helen Pluckrose, and Peter Boghossian, the scholars behind the hoax

Over the past 12 months, three scholars—James Lindsay, Helen Pluckrose, and Peter Boghossian—wrote 20 fake papers using fashionable jargon to argue for ridiculous conclusions, and tried to get them placed in high-profile journals in fields including gender studies, queer studies, and fat studies. Their success rate was remarkable: By the time they took their experiment public late on Tuesday, seven of their articles had been accepted for publication by ostensibly serious peer-reviewed journals. Seven more were still going through various stages of the review process. Only six had been rejected.

We’ve been here before.

In the late 1990s, Alan Sokal, a professor of physics … read more here
