A revision of the fossil genus Miocepphus and other Miocene Alcidae (Aves: Charadriiformes) of the Western North Atlantic Ocean

This study reviews and describes all known fossils of Alcidae from the Miocene of the western North Atlantic. Because the majority of alcid fossils recovered from Miocene sediments are allied with the genus Miocepphus Wetmore, 1940, the genus is revised here. Three new species of Miocepphus are described: Miocepphus bohaskai and Miocepphus blowi from the Early to Late Miocene, and Miocepphus mergulellus of uncertain Neogene age but probably Miocene. A new genus and species, Pseudocepphus teres, from the Middle and Late Miocene, has uncertain relationships within the Alcinae (a clade comprising Miocepphus, Alle, Uria, Alca and Pinguinus). The genus Alca is also reported from Late Miocene sediments. The newly recognised presence of three genera of the Alcinae in the Miocene of the North Atlantic indicates that the diversity of the subfamily was considerably greater than was evident previously. Miocepphus may be regarded as ancestral to modern Alcinae. The Alcinae as a group was well established in the Early Miocene, indicating that the divergence of the family Alcidae predates 20 Ma. The divergence of Uria and Alca predates 10 M

IT governance in SMEs: trust or control?

It is believed by many scholars that a small and medium-sized enterprise (SME) cannot be seen through the lens of a large firm. Theories which explain IT governance in large organizations and methodologies used by practitioners can therefore not be extrapolated to SMEs, which have a completely different economic, cultural and managerial environment. SMEs suffer from resource poverty, have less IS experience and need more external support. SMEs largely contribute to the failure of many IS projects. We define an out-sourced information system failure (OISF) as a failure of IT governance in an SME environment and propose a structure for stating propositions derived from both agency theory and theory of trust. The theoretical question addressed in this paper is: how and why do OISFs occur in SMEs? We have chosen a qualitative and positivistic IS case study research strategy based on multiple cases. Eight cases of IS projects were selected. We found that trust is more important than control issues like output-based contracts and structured controls for eliminating opportunistic behaviour in SMEs. We conclude that the world of SMEs is significantly different from that of large companies. This necessitates extra care to be taken on the part of researchers and practitioners when designing artefacts for SMEs

Nurturing the acorn: helping a small software company onto the CMM ladder

We report on an interaction between a University and a small software development company within the framework of a Teaching Company Scheme. By exploiting the peculiar environment offered by a TCS, the University was able to help the company introduce measures to improve their software development process. Not only have these measures moved the company from level 1 to level 2 of the Capability Maturity Model; they are doubtless also responsible, at least in part, for the company's survival. The fundamental features of the environment which supported this success are discussed, and it is suggested how the approach might be applied elsewhere, either within or independently of a funding framework such as TCS

Modeling the object-oriented software process: OPEN and the unified process

A short introduction to software process modeling is presented, particularly object-oriented modeling. Two major industrial process models are discussed: the OPEN model and the Unified Process model. In more detail, the quality assurance in the Unified Process tool (formally called Objectory) is reviewed

Towards a business-IT alignment maturity model for collaborative networked organizations

Aligning business and IT in networked organizations is a complex endeavor because in such settings, business-IT alignment is driven by economic processes instead of by centralized decision-making processes. In order to facilitate managing business-IT alignment in networked organizations, we need a maturity model that allows collaborating organizations to assess the current state of alignment and take appropriate action to improve it where needed. In this paper we propose the first version of such a model, which we derive from various alignment models and theories

Software Quality Skills in CMM-Based Development Environments

This paper examines the complex software development environment in which IS professionals commonly function today. Skills and competencies appropriate to this environment are increasingly related to managing change and adopting change agent roles. These skills and competencies are discussed in relation to complex and changing environments. Asurvey of IS professionals evaluates their perceptions of the importance of these competencies and their own capability in these areas. Observations and conclusions in this paper are primarily drawn from research on organizations that have initiated software process improvement initiatives (McGuire 1996a; 1996b; 1997)
