Do IS Curricular Guidelines Match Employer Expectations in Swedish IS Job Ads?

This study examines whether the IS 2010 Curriculum Guidelines and IS2020 Competency Model match employer expectations in Sweden. This is done by content analysis of 12 358 IS job advertisements, focusing on occupations, dispositions, technical skills, architecture, and the importance of programming. We find that: 1. The occupation group of ICT System Administration is much more important than in the IS 2010 and the IS2020 reports; 2. Enterprise Architecture is important in the ads and in the IS 2010 but not in the IS2020 report; 3. The most important personal dispositions in the ads are more important than in the IS 2010 and IS2020 reports; 4. Overall programming skills are important, but with less depth and extension than the IS2020 report specifies. 5. The IS2020 report’s technical stance over a more business-focused one is only partly supported. These differences might reflect the pre-dominantly US perspectives underlying the curricular guidelines

The Service Oriented Business Process and Separation of Concerns - Modelling paradigms for Architectures and Business Processes

This paper deals with the contemporary concern of business service-orientation. The paper suggests that service-oriented Business Information Systems Development (BISD) permits quality aspects, -“ilities” e.g.; maintainability and modifiability, of BISs and BISD. In addition, this paper departs from viewing a Business Information System (BIS) as services and suggests Separation of Concerns (SoC) as a prerequisite for achieving a well formed digital ecosystem. Besides knowledge transfer the purpose of this paper is to indicate the importance of architecture incorporating SoC when service-orienting a business with the contemporary Service Oriented Architecture (SOA). By realizing business logic service orientation in a nationwide research project our conclusion indicates that separate implementation of decision logic and process logic provides two different species of digital services implementing SoC. Consequently, responsible and eligible digital services become deliverables, service-orienting a part of a business representing vital quality aspects of ISD. The viability of separate digital services ensuring SoC facilitates the well-formed digital ecosystem i.e. the service oriented business process and business logic reusability and modifiability. The originality of this paper is based on a non-technical departure of SOA and on separation of process and decision logic as a mean to decreased child deaths due to preventable diseases

Business Rules Friendly or not so Business Rules Friendly Business Concepts Modelling - Early Experiences from a Business Rules Project on a Digital Vaccination Recommendation Service

WHO estimated in 2002 that 1.4 million children in the world would die from preventable diseases (World Health Organization, 2010). Each child is, or should be, immunized according to their national immunization schedule, which regulates i.e. vaccines and doses. Problems emerge when immigrant children should be transferred from one national vaccination schedule into another. This problem is quite evident in Sweden (Statistics Sweden, 2010). Vaccination practitioners have a hard time figuring out how to immunize an immigrant child. As a remedy for this situation, the VacSam project develops a Business Rules (BR) centric digital service through principles of (BR Approach), for providing unique vaccination recommendations. The service is designed using a commercial BRMS (BR Management Systems), which require a business concepts model. Thus, the paper presents early findings on how a business concepts model could be designed more or less BR-friendly. We have discovered, by designing, that a rigid, relational model approach is not BR-friendly. Instead, the concepts model should be de-signed to provide rule clarity and understandability. Thus, we draw the conclusion that a con-cepts model designed for persistent data storing, favouring a good quality relational model, is not rule friendly

Integrated Curriculum for a Bachelor of Science in Business Information Systems Design (BISD 2010)

Commentators on Information Systems (IS) education have urged the IS community to develop new and alternative IS curricula. The IS 2002 model curriculum has recently been revised. The new IS 2010 curriculum guidelines for undergraduate degree programs in Information Systems [Topi et al. 2010] has a curriculum structure to accommodate the education of several different professional roles within IS. This paper identifies one such role, the Business Information Systems Designer. It presents and argues for a new, integrated Bachelor of Science curriculum for Business Information Systems Design (BISD 2010) to educate for this role. The proposed curriculum focuses on the design and use of IS in business and has a strong design focus. The education focuses on developing and training a set of capabilities that enables the Business Information Systems Designer to participate in the design of business and IS in concert. Some examples of capabilities are communication and presentation skills, business and industry understanding, and high-level modeling. Consequently, the curriculum adopted a capabilities-driven pedagogical model in order to train specific skills. The paper presents the BISD 2010 with its specific expected learning outcomes, structure, and pedagogy, and also how the students should be able to fulfill the learning outcomes. The proposed curriculum differs from much of the current IS model curriculum discussions in a number of respects: (1) it is built on a notion of design, design science, and design as a profession, (2) it is based on a capability driven pedagogical model, (3) the curriculum is modeled for a European higher education context and the Bologna accord, and (4) it is not a model curriculum, but a specific, comprehensive, and ambitious curriculum for a degree program

Root formation and metallurgical challenges in laser beam and laser-arc hybrid welding of thick structural steel

Single-pass laser beam welding (LBW) of steel components with wall thickness of > 10 mm is of high interest due to enhanced productivity. Deep penetration LBW provides excessive hardness and certain quality issues such as root humping in flat position, which is associated with disability of surface tension to sustain melt dropout. High hardness is associated with fast cooling rates and shortage of filler wire transportation to the root of the fusion zone. Use of laser-arc hybrid welding (LAHW) can promote acicular ferrite by adding filler metal and additional heat input from the arc. However, LAHW may promote humping and adjustment of many parameters is required hindering its application. In this work, a 16 kW disk laser was used in butt welding of 12 mm and 15 mm thick plates with different bevelling geometries. Root humping occurred within a wide range of process parameters providing narrow process window. Twelve millimeter thick plates were successfully welded with a single-pass technique providing good quality of root by using zero air gap regardless bevelling geometry. Welding of 15 mm plates was more challenging, and the process was sensitive even with a slight parameter change. Improved results were achieved with application of small air gap. Acceptable hardness in both weld metal and heat affected zone (< 290 HV) was achieved for both plate thicknesses providing good toughness of minimum 27 J at −50°C.publishedVersio
