Project portfolio management: prioritising resources for change

While a number of studies have analysed portfolio management in goods firms, few have focused on the processes and practices within service firms. This research project investigated the attitudes, approach and practices geared towards project portfolio management (PPM) in UK-based financial service firms. An exploratory research approach is undertaken via in-depth interviews with key informants in 24 leading financial service companies. Data was also collected on the tools employed for PPM and the performance of the project portfolio. The results revealed considerable variation in the approach and effectiveness of PPM. There were clearly unresolved problems with PPM including PPM not being within the company's strategic context; firms being focused on managing project risk rather than building a balanced portfolio; a lack of understanding of project interdependencies and firms' reluctance to cancel projects once they have started

Service development success: a contingent approach by knowledge strategy

Purpose – Contingency theory suggests that effective strategies and structures are not universal but dependant upon situational factors. The purpose of this paper is to explore how the way service firms compete acts as a strategic contingency, moderating the effect of a new service development (NSD) system on innovation performance. Two knowledge‐based strategies are tested as contingency factors. One strategy adds value for customers via the delivery of personalized knowledge‐based services; the other strategy adds value by services exploiting codified knowledge. Design/methodology/approach – A sample of 70 large service enterprises is used to test a contingency model of service innovation. The NSD system is a synergistic meld of basic building blocks of NSD systems: people organized cross‐functionally, the discipline of formal processes for guiding development activities, and the deployment of enabling tools/technologies. Regression analysis is used to test the relative impact of these three elements on innovation performance contingent on the type of knowledge strategy employed. Findings – While each element of the NSD system has an effect on performance, the optimal design is contingent on the strategy the firm employs. If firms enact a personalization strategy, NSD systems that score high in the deployment of cross‐functional organization and disciplined processes are higher performers. If firms emphasize a codification strategy, NSD systems that score high in the deployment of tools/technologies are higher performers. Combinations of the two kinds of strategy permit the construction of a four‐cell classification of service firms. This typology is used to further explore the implications for how managers design NSD systems to optimize performance. Originality/value – This paper uses a contingency approach to demonstrate that an optimal NSD system is dependent upon the type of knowledge strategy firms deploy. The impact on performance of three components of NSD depends on the degree of either codification and/or personalization in the service offering. A novel approach based on the knowledge management literature is employed creating a typology of service firm strategies. This is the first time such a typology has been postulated

Using perovskite to determine the pre-shallow level contamination magma characteristics of kimberlite

It remains difficult to obtain reliable geochemical signatures of uncontaminated kimberlite magma from bulk rock studies due to the combined effects of crustal assimilation and element mobility during post-emplacement alteration processes. Groundmass perovskite (CaTiO3), a typical accessory phase, from Orapa (Botswana) and Wesselton (South Africa) kimberlites has been used to evaluate the isotope and trace element composition of the pre-contamination magmas and the effects of shallow level contamination. In-situ trace element signatures of Orapa and Wesselton perovskite grains are broadly similar and unaffected by crustal contamination. Single grain Sr-87/Sr-86 isotope ratios of perovskite from Orapa (0.7030-0.7036) are less scattered than bulk rock analyses (0.7063-0.7156), which are variably affected by contamination and late stage alteration. Initial Sr-87/Sr-86 isotope ratios of perovskite (0.7044-0.7049) from Wesselton overlap with published whole rock studies on fresh hypabyssal kimberlites (0.7042-0.7047). The limited intra-kimberlite variation in Sr isotope ratios recorded by the perovskite are unlikely to be due to crustal contamination as the calculated liquid compositions in equilibrium with the perovskite analysed typically have &gt;1500 ppmSr, and most common crustal lithologies underlying these kimberlites have relatively low Sr contents and are not highly radiogenic. Calculated pre-shallow level contamination magma compositions for Orapa and Wesselton have significantly fractionated LREE and highly variable non-smooth trace element patterns. Initial Sr and Nd isotope ratios of both kimberlites fall on the mantle Nd-Sr array with enriched Sr and slightly depleted Nd signatures, similar to Group I kimberlites. Overall, the trace element and isotopic composition of Orapa and Wesselton kimberlites are similar to the reported Group I kimberlites from southern Africa, which are derived by very low degrees of partial melting from a LREE depleted metasomatised sub-continental lithospheric mantle (SCLM) source.

Subsurface oil releases - Verification of dispersant effectiveness under high pressure

The main objective with this project was to study possible pressure dependency of droplet formation in case of a subsea blow out of oil and the effectiveness of subsea dispersant injection (SSDI). The droplet sizes documented by the SINTEF Silhouette Camera from comparable experiments (nozzle, oil type, flow rates, injection techniques and dispersant product) at ambient conditions (5 meters depth) and high pressure conditions (175 bar or 1750 meters depth) show no significant difference in droplet sizes as a function of pressure. This lack of a pressure effect was observed for both formation of large droplets from untreated oil and formation of smaller droplets by dispersant injection (1 and 2% dispersant dosage). This strongly indicates that SSDI effectiveness is not significantly influenced by hydrostatic pressure. These experiments were performed using stabilized dead oil without gas. Experiments with recombined oil & natura! gas ("live oil") were performed in a study later in 2015 (Brandvik et al., 2016b ).The American Petroleum Institute - API JITF 03publishedVersio

Internal marketing: a systematic review

Responding to the inadequacies and fragmentation of the Internal Marketing (IM) literature, this paper delivers a systematic review and synthesis of IM research. Based on an analysis of 349 articles, this work maps the evolution of IM research and identifies four distinct periods and six aggregated dimensions of IM research as determinants of employees’ responses to IM adoption. This article re-organizes IM knowledge and provides an integrated framework, in an attempt to address the limitations of contemporaneous IM knowledge. This paper contributes to the ongoing debate about the IM concept and its scope and presents an agenda for researchers

National Center for Biomedical Ontology: Advancing biomedicine through structured organization of scientific knowledge

The National Center for Biomedical Ontology is a consortium that comprises leading informaticians, biologists, clinicians, and ontologists, funded by the National Institutes of Health (NIH) Roadmap, to develop innovative technology and methods that allow scientists to record, manage, and disseminate biomedical information and knowledge in machine-processable form. The goals of the Center are (1) to help unify the divergent and isolated efforts in ontology development by promoting high quality open-source, standards-based tools to create, manage, and use ontologies, (2) to create new software tools so that scientists can use ontologies to annotate and analyze biomedical data, (3) to provide a national resource for the ongoing evaluation, integration, and evolution of biomedical ontologies and associated tools and theories in the context of driving biomedical projects (DBPs), and (4) to disseminate the tools and resources of the Center and to identify, evaluate, and communicate best practices of ontology development to the biomedical community. Through the research activities within the Center, collaborations with the DBPs, and interactions with the biomedical community, our goal is to help scientists to work more effectively in the e-science paradigm, enhancing experiment design, experiment execution, data analysis, information synthesis, hypothesis generation and testing, and understand human disease

Extrasolar planet science with the Antarctic planet interferometer

The primary limitation to ground based astronomy is the Earth's atmosphere. The atmosphere above the Antarctic plateau is different in many regards compared to the atmosphere at temperate sites. The extreme altitude, cold and low humidity offer a uniquely transparent atmosphere at many wavelengths. Studies at the South Pole have shown additionally that the turbulence properties of the night time polar atmosphere are fundamentally different to mid latitudes. Despite relatively strong ground layer turbulence, the lack of high altitude turbulence combined with low wind speeds presents favorable conditions for interferometry. The unique properties of the polar atmosphere can be exploited for Extrasolar Planet studies with differential astrometry, differential phase and nulling intereferometers. This paper combines the available data on the properties of the atmosphere at the South Pole and other Antarctic plateau sites for Extrasolar Planet science with interferometry

The role of knowledge management strategies and task knowledge in stimulating service innovation

Are service firms that enact strategies to manage their new service development (NSD) knowledge able to generate a sustainable competitive advantage (SCA)? Based on analysis of data from a large survey of service companies, the answer is yes. We find that companies employing the knowledge management strategies of codification and personalization reflect higher levels of NSD knowledge. However, the two strategies vary in their individual performance outcomes, with codification promoting NSD proficiency (an ability to execute NSD activities) and personalization promoting greater NSD innovativeness (market perception of the company as novel and as an innovator). When used together, the two strategies magnify NSD knowledge, which when combined with NSD proficiency and NSD innovativeness, promote a SCA. Therefore, companies planning to invest in a knowledge management system should heed the outcomes desired from their NSD process. A system based on documentation exemplifies a codification strategy and will drive NSD proficiency; a system emphasizing interpersonal communication exemplifies a personalization strategy and will drive NSD innovativeness. A system that blends the two strategies appears the most advantageous for service companies’ NSD efforts aiming to build a long-term sustainable competitive advantage
