Logical foundations of object-oriented and frame-based languages
- JOURNAL OF THE ACM
, 1995
"... We propose a novel formalism, called Frame Logic (abbr., F-logic), that accounts in a clean and declarative fashion for most of the structural aspects of object-oriented and frame-based languages. These features include object identity, complex objects, inheritance, polymorphic types, query methods, ..."

that come from object-oriented programming have direct representation in F-logic; other, secondary aspects of this paradigm are easily modeled as well. The paper also discusses semantic issues pertaining to programming with a deductive object-oriented language based on a subset of F-logic.
Usability Analysis of Visual Programming Environments: a `cognitive dimensions' framework
- JOURNAL OF VISUAL LANGUAGES AND COMPUTING
, 1996
"... The cognitive dimensions framework is a broad-brush evaluation technique for interactive devices and for non-interactive notations. It sets out a small vocabulary of terms designed to capture the cognitively-relevant aspects of structure, and shows how they can be traded off against each other. T ..."

techniques focus on different aspects and would make good complements. Insofar as the examples we used are representative, current VPLs are successful in achieving a good `closeness of match', but designers need to consider the `viscosity' (resistance to local change) and the `secondary notation
The grid file: an adaptable, symmetric multikey file structure
- In Trends in Information Processing Systems, Proc. 3rd ECZ Conference, A. Duijvestijn and P. Lockemann, Eds., Lecture Notes in Computer Science 123
, 1981
"... Traditional file structures that provide multikey access to records, for example, inverted files, are extensions of file structures originally designed for single-key access. They manifest various deficiencies in particular for multikey access to highly dynamic files. We study the dynamic aspects of ..."

A model for types and levels of human interaction with automation
- IEEE Transactions on Systems Man and Cybernetics – Part A: Systems and Humans
"... Abstract—Technical developments in computer hardware and software now make it possible to introduce automation into virtually all aspects of human-machine systems. Given these technical capabilities, which system functions should be automated and to what extent? We outline a model for types and leve ..."

Parental background, secondary school track choice
- and wages’, Oxford Economic Papers
, 2004
"... The way parents take influence on the education of their children is a crucial aspect of intergenerational mobility. Unlike in the UK or in the US, in Germany an important decision about which educational track to follow is made at a relatively early stage: after primary school, at the age of ten. I ..."

Persistence as an Aspect
, 2003
"... Persistence - the storage and retrieval of application data from secondary storage media - is often used as a classical example of a crosscutting concern. It is widely assumed that an application can be developed without taking persistence requirements into consideration and a persistence aspect plu ..."

Probabilistic models for unified collaborative and content-based recommendation in sparsedata environments
- In UAI ’01, 437–444
, 2001
"... Recommender systems leverage product and community information to target products to consumers. Researchers have developed collaborative recommenders, content-based recommenders, and a few hybrid systems. We propose a unified probabilistic framework for merging collaborative and content-based recomm ..."

-based recommendations. We extend Hofmann’s (1999) aspect model to incorporate three-way co-occurrence data among users, items, and item content. The relative influence of collaboration data versus content data is not imposed as an exogenous parameter, but rather emerges naturally from the given data sources. However
The work preference inventory: Assessing intrinsic and extrinsic motivational orientations. Journal of Personality and Social Psychology
- Journal of Applied Psychology
, 1994
"... The Work Preference Inventory (WPI) is designed to assess individual differences in intrinsic and extrinsic motivational orientations. Both the college student and the working adult versions aim to capture the major elements of intrinsic motivation (self-determination, competence, task involve-ment, ..."

The instrument is scored on two primary scales, each subdivided into 2 secondary scales. The WPI has meaningful factor structures
Regulation of translation via mRNA structure in prokaryotes and eukaryotes
- Gene
, 2005
"... The mechanism of initiation of translation differs between prokaryotes and eukaryotes, and the strategies used for regulation differ accordingly. Translation in prokaryotes is usually regulated by blocking access to the initiation site. This is accomplished via base-paired structures (within the mRN ..."

RNA itself, or between the mRNA and a small trans-acting RNA) or via mRNA-binding proteins. Classic examples of each mechanism are described. The polycistronic structure of mRNAs is an important aspect of translational control in prokaryotes, but polycistronic mRNAs are not usable (and usually not produced
