Assessment of Laparoscopic Skills Performance: 2D Versus 3D Vision and Classic Instrument Versus New Hand-Held Robotic Device for Laparoscopy

Introduction and Objectives. Laparoscopic surgery has undeniable advantages, such as reduced postoperative pain, smaller incisions, and faster recovery. However, to improve surgeons’ performance, ergonomic adaptations of the laparoscopic instruments and introduction of robotic technology are needed. The aim of this study was to ascertain the influence of a new hand-held robotic device for laparoscopy (HHRDL) and 3D vision on laparoscopic skills performance of 2 different groups, naïve and expert. Materials and Methods. Each participant performed 3 laparoscopic tasks—Peg transfer, Wire chaser, Knot—in 4 different ways. With random sequencing we assigned the execution order of the tasks based on the first type of visualization and laparoscopic instrument. Time to complete each laparoscopic task was recorded and analyzed with one-way analysis of variance. Results. Eleven experts and 15 naïve participants were included. Three-dimensional video helps the naïve group to get better performance in Peg transfer, Wire chaser 2 hands, and Knot; the new device improved the execution of all laparoscopic tasks (P < .05). For expert group, the 3D video system benefited them in Peg transfer and Wire chaser 1 hand, and the robotic device in Peg transfer, Wire chaser 1 hand, and Wire chaser 2 hands (P < .05). Conclusion. The HHRDL helps the execution of difficult laparoscopic tasks, such as Knot, in the naïve group. Three-dimensional vision makes the laparoscopic performance of the participants without laparoscopic experience easier, unlike those with experience in laparoscopic procedures.

PERFORMANCE CAPTURE: À PROCURA DAS MELHORES TÉCNICAS E ESTÉTICAS NO CONTEXTO DA ANIMAÇÃO DIGITAL

This paper investigates realism in character computer animation, which triggered the development of new techniques and aesthetic in spectacular cinema and contemporary culture. With the advent of motion or performing capture, animation has made possible that virtual characters or digital creatures reach higher levels in emotional acting, taking place in virtual cinematic worlds or even special effects movies. This technology, when placed at the service of imagination and fantasy can provide new dimensions in character motion and communication. In this context, projects like Peter Jackson’s (2001) The Lord of the Rings, James Cameron’s Avatar (2009) and more recently Steven Spielberg’s Tintin (2011) demonstrate that motion technology is constantly evolving, and it represents a credible option to explore new techniques and aesthetic in contemporary animation.

Performance measurement and management in Portuguese law enforcement

Performance measurement of police services is complicated by ambiguous and complex goal- and objectives-setting, and by the difficulties of measuring outputs. This article looks at the organizational and management changes being made in Portuguese police forces. The authors fill a gap in the literature on performance measurement in Portugal by taking a national approach to the study of how law enforcement agencies are introducing new management accounting changes. The article therefore widens the debate on performance measurement and performance improvements in law enforcement.

Use of Performance Measurement in the Public Sector: the case of the police service

Many public organisations have been under great pressure in recent years to increase the efficiency and transparency of outputs, to rationalise the use of public resources, and to increase the quality of service delivery. In this context, public organisations were encouraged to introduce the New Public Management reforms with the goal of improving the efficiency and effectiveness of the performance organisation through a new public management model. This new public management model is based on measurement by outputs and outcomes, a clear definition of responsibilities, the transparency and accountability of governmental activities, and on a greater value for citizens. What type of performance measurement systems are used in police services? Based on the literature, we see that multidimensional models, such as the Balanced Scorecard, are important in many public organisations, like municipalities, universities, and hospitals. Police services are characterised by complex, diverse objectives and stakeholders. Therefore, performance measurement of these public services calls for a specific analysis. Based on a nationwide survey of all police chiefs of the Portuguese police force, we find that employee performance measurement is the main form of measurement. Also, we propose a strategic map for the Portuguese police service.

Foucault’s Perspective of Performance Appraisal in Public Administration

The main purpose of performance appraisal in organizations is, or should be, to improve the engagement, learning process and progress of the employees and to align individual with team and organizational performance. However, performance appraisal can also be interpreted as an instrument of normalization, discipline and surveillance. This study thus aims to explore and discuss the complex schema of intrinsic and extrinsic objectives of performance appraisal system of the Portuguese public organizations (SIADAP - Performance Evaluation Integrated System). We have developed an exploratory and qualitative case study to capture appraisers and appraises perceptions. The data were analyzed in light of foucauldian theories. According to the qualitative data, namely the discourses of the appraisers and their subordinates, the SIADAP is seen as an instrument of control and dominance that aims to introduce political rationalities, limiting the career progression of the employees. Though some key points of Foucault’s perspective were identified, foucauldian framework revealed some limitations to capture all the complexity inherent to performance appraisal. This study opens new perspectives about the SIADAP and can be of major importance as far as political reflection about performance appraisal in public organizations is concerned.

Relationships between NPM, the use of PM practices and the organizational performance: empirical evidence from government agencies

Purpose – this paper has two main purposes: (1)explore if government agencies more oriented to NPM postulates are more willing to use PM practices and to improve their performance; and (2) investigate whether the fit between the use of PM practices and the organizationa performance is dependent upon from the capacity of agencies to adapt its structures to changes introduced by NPM reforms. Design/methodology/approach - this paper is based on the survey method and provides empirical evidence from Portuguese government agencies.Findings (mandatory) - Our findings suggest that government agencies that made structural arrangements under the NPM reforms are more willing to use PM practices and will perform better than other agencies. In addition, this paper show that therelationship between the use of PM practices and the organizational performance is dependent upon from the agencies capacity to adopt new structural arrangements under the NPM reforms.Practical implications – this paper has three main contributions: (1) contribute to knowledge about the relationship between the introduction of NPM changes in the use of PM practices; (2) contribute to clarify whether agencies more oriented to NPM postulates are improving performance; and (3) help to clarify the way the organizations should adapt their structures for to be more effective in the use of PM practices. Originality/value - The quantitative empirical research, based on the unique survey applied to Portuguese government agencies on this field, allow us to add to prior research mainly based on case studies and oriented to local governments (Budding, 2004).
