Strategic Grouping and Performance of Portuguese Manufacturing Firms: A Structural Equation Modelling Approach

Gomes, Carlos F., Augusto, Mário G., Yasin, Mahmoud M. 01 January 2010 (has links)
The objective of this study is to investigate the strategic factors that influence the overall performance of manufacturing organisations in different industries. Strategic groups were identified using cluster analysis and their overall performance was evaluated. Structural equation modelling was used to verify the existence of significant linkages between competitive factors and firms' overall performance within the identified strategic groups. The results of this study pointed out to the existence of a relationship between strategic group membership and firm's overall performance. Overall, the results tend to emphasise the importance of viewing manufacturing performance from a system-wide perspective.

Komunikační systém pro nevidomé - přenosná část / Communication system for the blind - the mobile part

Dadák, Jiří January 2008 (has links)
Orientation in big administration buildings can be very difficult for visually impaired people. Although most of the buildings are equipped with elevators, the buttons of which are designated with Braille characters and acoustic signals, it might be very difficult for the visually impaired to actually find the particular office. Even if there were descriptions in Braille at each office door, it would prove very complicating for the visually impaired individual to localize the descriptions in the first place, especially in case of a large number of offices in the building. That may also concern other important places, such as toilets, inside a building. In this thesis, I am going to present a design proposal of a communication system which uses transceivers placed at significant points in a building and receivers placed at the end of the white cane for orientation inside a building.

The Emerging Organizational Role of the Maintenance Function: A Strategic Perspective

Gomes, Carlos F., Yasin, Mahmoud M., Simões, Jorge M. 16 February 2021 (has links)
Purpose: With the growing importance of performance measurement and management, this exploratory study intends to examine the practices of maintenance managers with regards to maintenance measures, as used in their organizations. In this process, the study attempts to uncover the relevant maintenance performance dimensions from the perspectives of the surveyed managers. In addition, the mediating effect of information availability on the main performance measures utilization is studied. Design/methodology/approach: The research at hand is survey-based. It utilizes the responses of a sample of ninety-five (95) experienced maintenance managers to identify the most relevant maintenance performance measures. Factor analysis is then utilized to uncover the important dimensions of performance, as seen by the respondents. Additionally, using the Partial Least Squares method, several models were studied. Findings: The findings of this exploratory research appear to suggest that maintenance managers are beginning to broaden their perspective with regard to performance management. While machine and plant-related performance measures are still emphasized, maintenance managers are slowly moving toward a wider organizational orientation. While the manufacturing organizations are becoming more and more customer-oriented open systems, the maintenance function of these organizations is still, for the most part, operating under the semi-open system orientation. Overall, it appears that an emerging maintenance strategy is slowly taking shape. Research limitations/implications: For the most part, performance measures and measurement related to maintenance have not received enough attention from researchers. Therefore, the literature dealing with the different facets of performance in maintenance has not been forthcoming. The study attempts to fill this apparent gap in the literature. This is important, as maintenance managers are being asked to contribute to the achievement of the competitive strategies of their organizations. Therefore, they must quickly learn how to view maintenance from a coherent strategic organizational perspective. Such a perspective should help in integrating the maintenance, resources, capabilities, and technical know-how in order to serve the strategic goal of their organization. The research at hand is limited to a sample from Portugal. Therefore, the results and conclusions must be interpreted accordingly. Practical implications: As maintenance managers struggle to move from a machine-orientation to a more organizational-wide strategic orientation, they are often left with many questions and few answers. This study attempts to bring this problem to the spotlight so that it can receive more systematic empirical and practical research. In this context, the role of maintenance managers in the process of organizational strategy formulation should be examined. Originality/value: The study presented in this article has practical, as well as theoretical contributions. It deals with an area of performance measurement, which so far has been relatively ignored. It uses a system orientation (closed vs open), in addition to the strategic orientation (single vs multi-faceted strategy) in order to shed some light on the need to have consistency between the nature of the system and its strategic objective.

Gender Perceptions of Administrative Team Members Regarding Secondary Principals' Leadership Actions and Behaviors in Managing Change

Verrett, Shannon L 15 December 2012 (has links)
Abstract This cross-sectional survey study investigated middle and high school administrative team members’ leadership classifications and perceptions of secondary principals’ leadership actions and behaviors in the context of change and to what extent these perceptions are gender specific. In addition to gender, the study also examined the impact of race/ethnicity, age, campus level, length of employment in the district, length of time working with the principal, and closeness to the principals on leadership actions and behaviors. The results of the study are intended to highlight the importance and value of feminine-inspired leadership approaches and administrative team members’ perspectives of leadership in managing and leading the change process. The study targeted the leadership actions and behaviors of 39 middle school and 28 high school principals assigned to traditional secondary schools in the southwestern United States. Administrative team members’ perceptions of secondary school principals’ approaches to leadership served as the basis for the study, which investigated whether administrative team members perceived principals’ leadership actions or behaviors in a change context to be gender specific. Male and female administrative team members (n=210) were surveyed using the Leader Behavior Description Questionnaire (LBDQ), Form XII – fourth revision (Ohio State University, 1962). Based on survey results, secondary principals were classified as dynamic, considerate, passive, and structured leaders as rated by administrative team members using the LBDQ. The results of the study revealed that gender and school level of administrative team members did not influence the classification of secondary principals as dynamic, considerate, passive, or structured leaders. The ratings of those principals perceived as dynamic were statistically significantly higher than those of principals as passive and structured leaders. Out of 62 secondary principals, administrative team members classified principals as follows: dynamic leaders 63% (n=39), considerate leaders 5% (n=3), passive leaders 16% (n=10) and structured leaders 16% (n=10). Additionally, dynamic leaders received a statistically significant higher rating of closeness to principal when compared to passive and structured leaders. The findings of the study, which illuminate the perspectives of administrative team members with regard to secondary school principals, have implications for informing research on school leadership as well as educational leadership practices.
