Semiempirical calculations on the interaction between dimethyltin(IV) and DNA model system
1999
Abstract The interaction between a dinucleotide triphosphate duplex (DD), mimicking the DNA molecule, and the dimethyltin(IV) cation is studied by the semiempirical PM3 method. The results show that the interaction can occur involving the tin atom and the electron-donor centres of DD, requiring in some cases the presence of water molecules. In particular, the binding of the dimethyltin(IV) moiety with two adjacent phosphate oxygen atoms is allowed by the presence of water molecules coordinating to the tin atom. In this case the tin environment shows a geometry in agreement with 119 Sn Mossbauer and X-ray data.
OPTIMIZATION OF GREEN-BUILDING DESIGN PROCESSES - CASE STUDY
2016
The development of a green-building project following a specific reference standard such as LEED, brings new conditions and restrains for all subjects involved in the process. Such changes affect technicians, owners, bureaucracy and also the management tasks either during design or construction phases. Within this scope, project management plays a key role for the optimization of the design-project development. This research analyzes the design process of a single case-study project from the project management perspective, taking into consideration all the activities that negatively affected the project design development. The project selected for the scope of the research is a new school …
A Case Study on the Implementation of Stakeholder Management in Organizational Practice
2017
Recent research makes a strong argument for studying how organizations can implement a strategic stakeholder management approach. In this paper, we analyze an empirical case study in order to gain refined knowledge and develop ‘best’ implementation tactics, building on Plaza-Ubeda et al., (A case study of stakeholder identification and prioritization by managers, Journal of Business Ethics, 75: 1–23, 2010) conceptualization of the implementation of stakeholder integration (SI). The case study draws on a project concerning our own university, a private higher-education provider, which faces a new regulatory environment. In response to new legal measures, which include accounting for stakehol…
Inside service-intensive projects: Analyzing inbuilt tensions
2015
The purpose of this research is to identify typical professional and occupational groups in service-intensive projects, and illustrate the inbuilt tensions among them through the lens of institutional theory. The cases used for the study are a wind turbine business and a content management system project business. Our findings suggest that there are two professional groups (problem solvers, technology developers) and two occupational groups (lead generators, relationship developers) involved in these businesses. More importantly, their intergroup tensions are related to different institutionalized logics toward the conception of time (project temporality) and prioritization of different asp…
The combined use of quality management programs and work teams
2006
PurposeThe main goal of the work presented here is the study and comparative analysis of the changes that take place in the structure of organizations when managers decide to establish work teams in the context of quality management. It can be observed that team characteristics change and adapt to evolving management programs.Design/methodology/approachThe authors selected a qualitative research method, in particular the case study methodology. The comparative analysis of organizational changes was analyzed in three different business units that had implanted advanced quality management programs using work teams.FindingsThere is a relationship between the quality management approach and the…
KM/OM/OL systems and technologies
2004
The systems and technologies mini track of the knowledge management, organizational memory and organizational learning research cluster addresses technical issues and tools for building and supporting knowledge management, organizational memory, and organizational learning systems. Sixteen papers were considered in this mini track. We wish to express our thanks to all of those authors who submitted their work. We would also like to thank the 31 individuals who gave their time and effort in providing reviews of the submitted manuscripts. The mini track could not exist without their diligent efforts. The six accepted papers describe both conceptual and working systems.
Dual Substituent Parameter Modeling of Theoretical, NMR and IR Spectral Data of 5-Substituted Indole-2,3-diones
2002
Correlations of AM1 and PM3 theoretical data, 13C-NMR substituent chemical shifts (13C-SCS) and IR carbonyl group wave numbers [ν(C3â•ÂO)] were studied using dual substituent parameter (DSP) models for 5-substituted indole-2,3-diones. For the C7 atom a reverse substituent effect attributed to extended À-polarization was observed. On the other hand, the DSP approaches for the C3 atom showed normal substituent effects with some contribution of reverse effect supported strongly by 13C-SCS correlations. In the ν(C3â•ÂO) and p(C3â•ÂO) DSP correlations the field effect contribution predominates over the resonance effect, which justifies the using of earlier suggested vibrational cou…
Using Activity Theory in Developing Instructial Tools for Project Management Studies
2014
Competence and skills of the project manager are significant to project success. The skills needed in project managersâ work cannot be learned only by reading the books or a lecture hall; one learns them by practice. Therefore, an important challenge for educational institutions is to develop pedagogical practices that allow students to participate in working life projects and to confront real-life problems. Project-based learning (PBL) offers a model that enables students to practice the skills and competences needed in working life projects by utilizing real-world work assignments in time-limited projects. Using PBL method alone does not necessarily guarantee learning result. In order t…

A Comparative Analysis of Performance Management Systems
2012
Performance management is maturing as an effective organizational approach in public organizations around the world, but the existing models have limitations that must be addressed. The international comparative case study analysis in this article presents policy recommendations and organizational strategies on how regional governments can create more robust performance management systems for higher levels of accountability and transparency in a time of global economic crisis. These include the consideration of organizational structure regarding alignment, control, and culture, the positive impact of performance management legislation, the role of executive leadership, and the need for an i…
