Curriculum Guidelines for Undergraduate Programs in Data Science
The Park City Math Institute (PCMI) 2016 Summer Undergraduate Faculty Program
met for the purpose of composing guidelines for undergraduate programs in Data
Science. The group consisted of 25 undergraduate faculty from a variety of
institutions in the U.S., primarily from the disciplines of mathematics,
statistics and computer science. These guidelines are meant to provide some
structure for institutions planning for or revising a major in Data Science
Model-driven performance evaluation for service engineering
Service engineering and service-oriented architecture as an
integration and platform technology is a recent approach to software systems integration. Software quality aspects such as performance are of central importance for the integration of heterogeneous, distributed service-based systems. Empirical performance evaluation is a process of
measuring and calculating performance metrics of the implemented software. We present an approach for the empirical, model-based performance evaluation of services and service compositions in the context of model-driven service engineering. Temporal databases theory is utilised
for the empirical performance evaluation of model-driven developed service systems
From the classroom to an opinion note: complementary analysis of the genetic structure of the neotropical tree manilkara zapota (L) P. Royen (Sapotaceae)
Here, we describe a learning strategy that results an excellent choice for a first approach of students to produce scientific knowledge that can be confronted in the scientific field as well as recognize in this knowledge the transferability to the natural resources management. Nowadays, the availability of several Population Genetics software together with public molecular database represents a valuable tool of great assistance for teachers of this discipline. In this way, we implemented a lecture where the students worked with empirical data set from a recent published article. The students joined theoretical concepts learned, computational software free available and empirical data set. The development of the activity comprised four steps: i) estimate population genetics parameters using software recommended by teachers, ii) understand results in a biological sense, iii) read the original manuscript from dataset authors and iv) compare both results in a comprehensive way. The students assumed the challenge under a reflective look and they kept a very fruitful discussion playing a role of population geneticists. Their exchange of ideas allowed them arrive to the conclusion that Manilkara zapota populations keep high levels of genetic diversity, although Ancient Maya left traces in the genetic makeup of these non-native populations with different management histories.Fil: Barrandeguy, Maria Eugenia.

Computer Administering of the Psychological Investigations: Set-relational Representation
Computer administering of a psychological investigation is the computer
representation of the entire procedure of psychological assessments - test
construction, test implementation, results evaluation, storage and maintenance
of the developed database, its statistical processing, analysis and
interpretation. A mathematical description of psychological assessment with the
aid of personality tests is discussed in this article. The set theory and the
relational algebra are used in this description. A relational model of data,
needed to design a computer system for automation of certain psychological
assessments is given. Some finite sets and relation on them, which are
necessary for creating a personality psychological test, are described. The
described model could be used to develop real software for computer
administering of any psychological test and there is full automation of the
whole process: test construction, test implementation, result evaluation,
storage of the developed database, statistical implementation, analysis and
interpretation. A software project for computer administering personality
psychological tests is suggested
Myths and Realities about Online Forums in Open Source Software Development: An Empirical Study
The use of free and open source software (OSS) is gaining momentum due to the
ever increasing availability and use of the Internet. Organizations are also
now adopting open source software, despite some reservations, in particular
regarding the provision and availability of support. Some of the biggest
concerns about free and open source software are post release software defects
and their rectification, management of dynamic requirements and support to the
users. A common belief is that there is no appropriate support available for
this class of software. A contradictory argument is that due to the active
involvement of Internet users in online forums, there is in fact a large
resource available that communicates and manages the provision of support. The
research model of this empirical investigation examines the evidence available
to assess whether this commonly held belief is based on facts given the current
developments in OSS or simply a myth, which has developed around OSS
development. We analyzed a dataset consisting of 1880 open source software
projects covering a broad range of categories in this investigation. The
results show that online forums play a significant role in managing software
defects, implementation of new requirements and providing support to the users
in open source software and have become a major source of assistance in
maintenance of the open source projects
