Hadronic Parity Violation: an Analytic Approach

Using a recent reformulation of the analysis of nuclear parity-violation (PV) within the framework of effective field theory (EFT), we show how predictions for parity-violating observables in low-energy light hadronic systems can be understood in an analytic fashion. It is hoped that such an analytic approach may encourage additional experimental work as well as add to the understanding of such parity-violation phenomena, which is all too often obscured by its description in terms of numerical results obtained from complex two-body potential codes.Comment: 49 pages, 4 figures, dedicated to the memory of Dubravko Tadi

A Nation of Guinea Pigs. By Marshall S. Shapo

Empati mellan interaktionsdesigners och utvecklare är viktigt för att samarbetet ska fungera och för att parterna ska kunna kommunicera med varandra. Detta tillsammans med förmågan att se situationer ur varandras perspektiv är något som påverkar samarbetet avsevärt. Empati bygger på förståelse, förstår man andra personers perspektiv kan man också känna empati för andra personers prioriteringar och ta hänsyn till dessa. Det är också av stor vikt att interaktionsdesigners och utvecklare har en gemensam bild av situationen och de projekt de arbetar med. En förstudie som genomfördes under hösten 2013 visade att interaktionsdesigners upplevde att utvecklare inte känner empati för deras arbete vilket de upplevde har skapat problem i samarbetet. För att få en djupare förståelse för detta genomfördes en fenomenologisk studie där nio interaktionsdesigners intervjuades. Resultatet visade att interaktionsdesigners upplevde att utvecklare ibland ändrar i en design utan att diskutera detta med dem vilket gör att syftet med designen kan falla bort och i vissa fall känner interaktionsdesigners inte igen sin design i den färdiga produkten. De upplevde även att utvecklare ser på design som något onödigt eller lyxigt som inte behövs för att ta fram bra produkter. Utvecklingen har istället varit det som ses som viktigt och prioriterats i projekten. Interaktionsdesigners har även upplevt denna bristande förståelse på organisatorisk nivå, exempelvis när kunder inte köpt deras tjänster fram tills att produkten är färdig. Därför har det inte funnits möjlighet till avstämning mellan interaktionsdesigner och utvecklare under tiden utvecklare implementerar designen. Missförstånd har då uppstått och produkten har inte nått sin fulla potential. Vissa anser att en stor del av problemet grundar sig i detta, att utvecklare inte i sitt arbete uppmuntras diskutera designen eller följa upp implementationen med den som skapat designen.Empathy between interaction designers and developers is important in order for the collaboration to work and for them to be able to communicate with each other. This, as well as the ability to see situations from other persons perspective, is something that affects collaboration significantly. Empathy builds on understanding, if one understands other persons perspective one can also feel empathy for other persons priorities and take these in to consideration. It is also of great importance that interaction designers and developers have a common picture over the situation and the projekts they are working with. A pre study was carried out in the fall of 2013 and showed that interaction designers felt that developers does not have empathy for their work, which they experienced has created collaboration problems between them. In order to create a deeper understanding for this, a phenomenological study was carried out where nine interaction designers were interviewed. The result showed that interaction designers felt that developers sometimes changes a design without discussing it with them, which can lead to deviations from the purpose of the design and in some cases the designers does not recognize their design in the developed product. The interaction designers also felt that developers think design is something unnecessary or luxury that is not needed in order to create successful products. The development is instead seen as what is important and what is prioritized in the projects. Interaction designers have also experienced this lack of understanding at an organizational level, for example when customers have not bought their service all the way, until the product is done and ready for release. Because of this there has not been possible for the interaction designers and the developers to talk to each other during the development process. Misunderstandings have then occured and the product has not lived up to its full potential. Some believe that a big part of the problem originates from this, that developers in their work is not encouraged to discuss the design with the interaction designer that created it

Neutrinos and the Standard Model

Since their "discovery" by Pauli in 1930, neutrinos have plaed a key part in confirmation of the structure of the standard model of strong and electroweak interactions. After reviewing ways in which this has been manifested in the past, we discuss areas in which neutrinos continue to play this role.Comment: 16 page latex file, Talk presented at Carolina Neutrino Workshop, Columbia, SC, March 200

An introduction to methods of effective field theory is given. Examples are presented, including Rayleigh scattering from nonrelativistic quantum mechnics, chiral perturbation theory/QCD as well as electromagnetic and weak interactions of nucleons.Comment: 12 page latex file, Talk given at European Few Body Physics Meeting, Evora, Portugal, September 200

Low Energy Compton Scattering and Nucleon Structure

The low energy virtual Compton scattering process $eN\to e'N\gamma$ offers a new and potentially high resolution window on nucleon sturcture via measurement of so-called generalized polarizabilities (GPs). We present calculations of GPs within heavy baryon chiral perturbation theory and discuss present experimental efforts.Comment: Talk given at Workshop on "Physics of Mesons, Baryons and Nuclei," Cracow, May 1998, in celebration of 60th birthday of Prof. Josef Spet
