The Impact

Co-production is a solution by which the government provides public services. Co-production theory is built upon Western experience and currently focuses on the types of co-production in different policy stages, the barriers and governance strategies for co-production. However, little attention is paid to how political background will influence the co-production process. To fill the gap, we analyzed a case of co-production that occurred in China, and we characterized the political background as consisting of three main political features: political mobility, central–local relations, and performance measurement. Based on an in-depth case study of a government project in a medium-sized Chinese city, the impact and the changes of political features affecting governmental projects in different co-production stages are analyzed and assessed. We find that political features play a critical role in the co-production of China’s large government projects and may separately and jointly affect co-production. Government performance measurement affects the co-design and co-implementation of projects. Political mobility and changes in local government and performance measurement also affect the co-implementation continuity of the project. Political focus affects the co-design of projects. Central-local relations influence the support from higher government and the actual practices of lower government in the co-implementation stage.

The Impact

Research suggests, according to Branch, Ramsay, and Barker (2013), that a significant number of people are exposed to persistent abusive treatment within the workplace, with the majority of studies within Europe indicating that between 10% and 15% of the workforce are exposed to workplace bullying (Zapf, Escartin, Einarsen, Hoel, & Vartia, 2011), with North American research reporting similar prevalence rates. This is a significant, ongoing dilemma for researchers and practitioners, for which an agreed resolution would be useful because of legal and policy implications. Hence, the purpose of this chapter is on the impact of organizational trauma on workplace behavior and performance based on workplace bullying. The chapter is based on a case study regarding a program that is funded by the Department of Education within a community college in the State of California. The community college is one of four community colleges under the same community college district.

Risk identification and prioritization is very essential activity in any successful strategic risk management process. Developing a plan for dealing with such problems reduces the impact of unexpected risks and failures while prioritizing risks draws attention, efforts and resources to the risks with great impact on projects success. The aim of this paper, is to identify the critical risk factors in an ERP project through a case study of a successful implementation of an ERP system in a Sudanese organization and to understand how the organization implemented the appropriate controls to minimize its business risks impact. To achieve this objective, a number of key articles were reviewed and analyzed to understand the different critical risk factors influence ERP implementation. New risk factors and controls influence ERP implementation have been identified. A new model of ERP implementation critical risk factors was developed. Furthermore, the risk factors were classified into categories, probability, impact and proximity, then using a prioritizing tool, the results of this study contributes to risks identification and prioritization by pointing to the less priority and the most critical risk factors.

The Impact

Direct Drive Open Rotors (DDORs) have the potential to significantly reduce fuel consumption and emissions relative to conventional turbofans. However, this engine architecture presents many design and operational challenges both at engine and aircraft level. At preliminary design stages, a broad design space exploration is required to identify potential optimum design regions and to understand the main trade offs of this novel engine architecture. These assessments may also aid the development process when compromises need to be performed as a consequence of design, operational or regulatory constraints. Design space exploration assessments are done with 0-D or 1-D models for computational purposes. These simplified 0-D and 1-D models have to capture the impact of the independent variation of the main design and control variables of the engine. Historically, it appears that for preliminary design studies of DDORs, Counter Rotating Turbines (CRTs) have been modelled as conventional turbines and therefore it was not possible to assess the impact of the variation of the number of stages (Nb) of the CRT and rotational speed of the propellers. Additionally, no preliminary design methodology for CRTs was found in the public domain. Part I of this two-part publication proposes a 1-D preliminary design methodology for DDOR CRTs which allows an independent definition of both parts of the CRT. A method for calculating the off-design performance of a known CRT design is also described. In Part II, a 0-D design point efficiency calculation for CRTs is proposed and verified with the 1-D methods. The 1-D and 0-D CRT models were used in an engine control and design space exploration case study of a DDOR with a 4.26m diameter an 10% clipped propeller for a 160 PAX aircraft. For this application: • the design and performance of a 20 stage CRT rotating at 860 rpm (both drums) obtained with the 1-D methods is presented. • differently from geared open rotors, negligible cruise fuel savings can be achieved by an advanced propeller control. • for rotational speeds between 750 and 880 rpm (relatively low speeds for reduced noise), 22 and 20 stages CRTs are required. • engine weight can be kept constant for different design rotational speeds by using the minimum required Nb. • for any target engine weight, TOC and cruise SFC are reduced by reducing the rotational speeds and increasing Nb (also favourable for reducing CRP noise). However additional CRT stages increase engine drag, mechanical complexity and cost.

Online learning has been an area of tremendous growth in recent years [1], further accelerated by necessity during the coronavirus pandemic [2]. Without the feedback provided by synchronous sessions, however, instructors may lack ongoing insight into students’ progress and performance in fully asynchronous online offerings. Providing greater visibility into students’ online learning behavior has several potential benefits: 1) teachers who seek to provide live sessions that depend on knowledge from asynchronous resources will have a better gauge of students’ preparation; 2) enhanced understanding of the relationship between student pacing and performance can help teachers and researchers characterize the impact of timely engagement with online course material; 3) providing a means of monitoring the effect of changes in course structure or incentives may guide course designers/planners in continuous improvement; and 4) visualizations that illustrate the relationship between students’ course progress and performance have the promise of allowing teachers to take steps early to positively affect students’ outcomes. In this visual case study, visualizations are provided for exploration of the relationship between student progress and performance in an online medicine-related course.

Abstract Background Many undergraduate students majoring in science, technology, engineering, and mathematics (STEM) fields lack experience in collaborative thinking, limiting their effectiveness as they enter careers in academic and industrial environments. The SyBBURE Searle Undergraduate Research Program has incorporated a team-based design component into its curriculum to fill this gap in training. This design framework, called Vigilante Innovation (VIX) to highlight its emphasis on self-initiation and action, has evolved into a multi-semester-long group undertaking that combines just-in-time training in entrepreneurship and project design with student-driven collaborations aimed at solving a real-world problem. We hypothesize that this framework provides a hands-on, realistic workplace simulation task through which students can develop an understanding of teamwork. Results Using a case-study approach, we discuss the development of the VIX design framework since its inception in 2014 and assess the impact of the VIX framework on student learning and growth using a student survey from 2016 to 2017 and student interviews from 2018. Conclusions A flexible approach, an annualized project timeline, a student-driven prototyping space, and self-selecting project areas emerged as key contributors to the successful implementation of the VIX design and to deepened student learning. The diversity of VIX teams, the self-reported success of student projects, and student interviews indicate that students who participate in VIX possess an in-depth understanding of team-based strategies. These findings support the VIX framework as an effective method of providing undergraduates in STEM fields with efficient and meaningful exposure to the team-based entrepreneurial skills that are vital in their future careers. Additional work is needed to determine if this approach has a long-term impact on student success in team-based environments.

Objective: School-based prevention interventions informed by the World Health Organization Health Promoting School (HPS) framework aim to improve the health and wellbeing of school-aged children, yet few studies describe factors influencing the successful implementation of this framework in secondary schools. This study sought to explore why and how secondary schools might implement the HPS framework and factors contributing to success. Design: Qualitative case study. Setting: A single secondary school in Victoria, Australia, purposefully selected due to local recognition of an HPS policy. Method: Data collection included semi-structured interviews, document retrieval, drawings and ethnographic observation. Data were analysed using framework analysis. Results: The school had elected to implement the policy as it aligned with its existing health and wellbeing policy framework and provided a flexible yet evidence-based framework to guide a whole-of-school approach to promoting health and wellbeing. Success was perceived to be dependent on selecting easier health priority areas to address initially, the allocation of a designated team to guide policy implementation and access to a skilled health promotion worker to assist implementation. Conclusion: Study findings highlight potential reasons why and how secondary schools might implement the HPS framework and factors contributing to success. Further research is warranted to enhance the transferability of these findings and explore the impact of the HPS framework in secondary schools.

The introduction of new Air Traffic Management (ATM) concepts such as Trajectory Based Operations (TBO) may produce a significant impact in all performance areas, that is, safety, capacity, flight efficiency, and others. The performance framework in use today has been tailored to the operational needs of the current ATM system and must evolve to fulfill the new needs and challenges brought by the TBO content. This paper presents a novel performance assessment framework and methodology adapted to the TBO concept. This framework can assess the key performance areas (KPAs) of safety, capacity, and flight efficiency; equity and fairness are also considered in this research, in line with recent ATM trends. A case study is presented to show the applicability of the framework and to illustrate how some of the complex interdependencies among KPAs can be captured with the proposed approach. This case study explores the TBO concept of “strategic 4D trajectory deconfliction,” where the early separation tasks of 4D trajectories at multisector level are assessed. The framework presented in this paper could potentially support the target-setting and performance requirements identification that should be fulfilled in the future ATM system to ensure determined levels of performance.

The study examined the impact of leadership style on organizational performance in selected Banks, in Ibadan Nigeria. Purposive sampling technique was adopted in selecting a total of sixty (60) respondents as sample for the study, while relevant data was gathered with the aid of a structured questionnaire. One hypothesis was formulated and inferential statistical tool was used to analyze the data specifically Pearson product moment correlation was used to examine the relationship between leadership style dimensions and organizational performance, while Regression analysis was used to examine the significant effect of leadership style dimensions on followers and performance. Findings showed positive and negative correlation between leadership style dimensions and organizational performance. It was also found that leadership style dimensions jointly predict organizational performance, which counted for 23% variance of performance. The study concluded that transformational and democratic leadership style should be employed by the Banks’ management in order to wax stronger in a global competitive environment.
