Web Single Sign-On Authentication using SAML
Companies have increasingly turned to application service providers (ASPs) or Software as a Service (SaaS) vendors to offer specialized web-based services that will cut costs and provide specific and focused applications to users. The complexity of designing, installing, configuring, deploying, and supporting the system with internal resources can be eliminated with this type of methodology, providing great benefit to organizations. However, these models can present an authentication problem for corporations with a large number of external service providers. This paper describes the implementation of Security Assertion Markup Language (SAML) and its capabilities to provide secure single sign-on (SSO) solutions for externally hosted applications
The Geometry of the Gibbs-Appell Equations and Gauss' Principle of Least Constraint
We present a generalisation of the Gibbs-Appell equations which is valid for general Lagrangians. The general form of the Gibbs-Appell equations is shown to be valid in the case when constraints and external forces are present. In the case when the Lagrangian is the kinetic energy with respect to a Riemannian metric, the Gibbs function is shown to be related to the kinetic energy on the tangent bundle of the configuration manifold with respect to the Sasaki metric. We also make a connection with the Gibbs-Appell equations and Gauss' principle of least constraint in the general case

Is Understanding Reducible?
Despite playing an important role in epistemology, philosophy of science, and more recently in moral philosophy and aesthetics, the nature of understanding is still much contested. One attractive framework attempts to reduce understanding to other familiar epistemic states. This paper explores and develops a methodology for testing such reductionist theories before offering a counterexample to a recently defended variant on which understanding reduces to what an agent knows
Recent work on the proof paradox
Recent years have seen fresh impetus brought to debates about the proper role of statistical evidence in the law. Recent work largely centres on a set of puzzles known as the âproof paradoxâ. While these puzzles may initially seem academic, they have important ramifications for the law: raising key conceptual questions about legal proof, and practical questions about DNA evidence. This article introduces the proof paradox, why we should care about it, and new work attempting to resolve it

Byggbranschen stĂ„r inför flera utmaningar eftersom vĂ„r medvetenhet om omgivningen ökar och ett mer hĂ„llbart förhĂ„llningssĂ€tt önskas. Ett byggprojekt Ă€r traditionellt begrĂ€nsat av tid, kostnad och kvalitet men det har blivit ett mĂ„ste att fokusera pĂ„ miljöaspekter ocksĂ„. Att fokusera pĂ„ miljöaspekter Ă€r en av de stora utmaningar som projekterings- och projektledare stĂ„r inför i dag. Detta Ă€r en utmaning eftersom hĂ„llbart byggande kan uppnĂ„s pĂ„ mĂ„nga olika sĂ€tt och projektledare har inte djup kunskap inom omrĂ„det. Ny kunskap behövs om till exempel miljöklassificeringar och lĂ„ngsiktiga fördelar med hĂ„llbart byggande. För att stödja design -och projektledare i sitt dagliga arbete anvĂ€nder mĂ„nga företag verksamhetssystem som ett verktyg för att lagra och dela kunskap. Systemet ska sĂ€kerstĂ€lla att alla arbetar pĂ„ rĂ€tt sĂ€tt och levererar lĂ€mplig kvalitet, men systemet bör ocksĂ„ stödja de anstĂ€llda i deras arbete. Konsulter behöver kunna ge rĂ„d, stöd och kontrollera de miljömĂ€ssiga aspekterna av projekten. För att göra detta behöver de omfattande miljöledningsstöd frĂ„n sitt verksamhetssystem. Denna studie Ă€r kvalitativ dĂ€r intervjuer har genomförts och en enkĂ€t skickats ut till WSPâs projektledningsavdelningen i Stockholm. Författaren har gĂ„tt in i verksamhetssystemet och observerat och kartlagt innehĂ„llet för att kunna föreslĂ„ förbĂ€ttringar. Syftet med denna forskning Ă€r att undersöka hur ett verksamhetssystem kan stödja projekt -och projekteringsledare inom hĂ„llbarhetsfrĂ„gor. Genom att göra detta förbĂ€ttras kunskapshanteringen. Resultaten tyder pĂ„ att ett verksamhetssystem och miljöstyrningen bör integreras i ett system. Systemet mĂ„ste vara snabbt och innehĂ„lla en effektiv sökfunktion för att förbĂ€ttra tillgĂ€ngligheten. Det mĂ„ste finnas lĂ€mpliga verktyg som checklistor, mallar och riktlinjer för att utföra miljöuppgifter. Dessutom behöver de anstĂ€llda tillrĂ€ckliga kunskaper om hĂ„llbarhet för att kunna anvĂ€nda verktygen och lyckas bedriva hĂ„llbar projektledning. Det bör ocksĂ„ finnas ett Ă„terkopplingsverktyg för de anstĂ€llda som uppmuntrar dem att komma in med förslag och synpunkter som bidrar till kunskapsdelning i företaget
Perspectives on Human Nature and Their Implications for Business Organizations
Employing psychological principles to reform the structure and agendas of business organizations increases employee fulfillment. This Essay proposes changes in corporate structure in order to nurture employee\u27s mental health in a way that also benefits companies by resulting in greater employee productivity. This Essay argues that the decentralization of business organizations and greater employee involvement in decision-making will improve both quality of life and the environment
A Symmetric Product for Vector Fields and its Geometric Meaning
We introduce the notion of geodesic invariance for distributions on manifolds with a linear connection. This is a natural weakening of the concept of a totally geodesic foliation to allow distributions which are not necessarily integrable. To test a distribution for geodesic invariance, we introduce a symmetric, vector field valued product on the set of vector fields on a manifold with a linear connection. This product serves the same purpose for geodesically invariant distributions as the Lie bracket serves for integrable distributions. The relationship of this product with connections in the bundle of linear frames is also discussed. As an application, we investigate geodesically invariant distributions associated with a left-invariant affine connection on a Lie group
