Data-Centric Hierarchical Distributed Model Predictive Control for Smart Grid Energy Management

The smart grid energy management with variable renewable energy resources presents many challenges to the grid operation. An optimized solution to manage the available resources is necessary to achieve reliable operation. This paper presents the hierarchical distributed model predictive control (HDMPC) to solve the energy management problem in the multitime frame and multilayer optimization strategy. The HDMPC combines the concept of enabling the optimization over long time-horizon for a centralized supervisory management (SM) layer and another short time-horizon during high-power variability for a distributed coordination management (CM) layer. The information exchange and interoperability between different layers are provided through the data-centric communication approach. The SM (upper layer) works to present the grid operator with certain operational plans and gives the guidelines to the CM (lower layer). The CM has the responsibility to coordinate the relationship between the centralized optimization objectives and the physical power system layer. The proposed HDMPC control was verified both numerically and experimentally. The obtained simulation results show that the control strategy proposed here is successful and combines the benefits of both the centralized and distributed control for a global solution of the grid operation problem. The experimental results demonstrate the feasibility of the real-time implementation of the proposed system for deployment to control future smart grid assets.

The Relationship between the Management Intervention of Venture Capital Institutions and the Performance of Start-Up Enterprises

Based on the two theoretical hypotheses of “screening theory” and “cultivation theory”, this paper reviews the concepts and motivations of venture capital institutions’ management intervention, and summarizes the two modes of venture capital institution management intervention: supervisory control intervention and operational management intervention. Based on two management intervention modes, this paper divides the management involvement into three levels: no management intervention, moderate management intervention, and deep management intervention. This paper systematically analyzes the influence mechanism of the two management intervention modes and the degree of involvement on the performance of venture enterprises, and constructs a comprehensive theoretical framework of venture capital and entrepreneurial enterprise performance, which provides theoretical support and research direction for follow-up research.

Boards of Governors’ Roles and Management of Government Aided Secondary Schools in Kyenjojo District, Uganda

This study sought to establish the relationship between boards of governors’ (BOGs) roles and management of government aided secondary schools in Kyenjojo District. The objectives were to establish the relationship between BOGs’ planning role and management of government aided secondary schools, to establish the relationship between BOGs’ supervisory role and management of government aided secondary schools, to establish the relationship between BOGs’ control role and management of government aided secondary schools; and to determine the major predictor of management of government aided secondary schools out of the three aspects of BOGs’ roles. A correlational research design was used. A total of 90 respondents drawn from 108 BOGs and nine head teachers were selected as sample for the study using stratified random sampling and census inquiry respectively. The instruments used were questionnaire and interview guide. Quantitative data was analysed using Pearson product-moment correlation and regression, while thematic analysis was used on qualitative data. The study found a statistically moderate positive and significant relationship between BOGs’ planning role and management of government aided secondary schools (r=.626, p=.000); a statistically moderate positive and significant relationship between BOGs’ supervisory role and management of government aided secondary schools(r=.591, p=.000); and a statistically weak positive and significant relationship between BOGs’ control role and management of government aided secondary schools(r=.280, p=.015). All the three aspects of BOGs’ roles account for 38.4% of the influence on management of government aided secondary schools in Kyenjojo district (adjusted r2=0.384, p=.000). The researchers recommend that BOGs should be well trained in management of schools in order to be effective in their work. Head teachers should not be dictators but create a conducive climate for planning, supervision and control by the BOGs.

Perceptions on safety climate: a case study in the Omani construction industry

Generally, a mature safety climate and a rich safety culture contribute to achieving a safe workplace. The purpose of this paper is to examine the understanding of using safety climate and to make explicit some of the main elements that have a greater impact in the construction industry in Oman. Relevant safety climate factors from literature have been identified using specific search criteria, which resulted in 62 factors spanning over a period of 37 years from 1980 to 2017. The results of face-to-face interviews with construction professionals from chosen construction companies in Oman that show a high level of safety performance are also presented. The result shows that management commitment; alignment and integration of safety as a value; accountability across the board; supervisory management; empowerment and involvement of workers; improvement of communication; and training and education are some of the main elements that significantly affect safety climate in Oman. The common safety climate factors reported in this research are based on the views of selected interviewees working in the construction industry in Oman. It is suggested that these factors may be validated further considering views of other members of the construction team, before being used for safety climate assessment.

The Impact of Supervisory Management on Extension Agent Job Satisfaction

The relationship between a supervisor and his/her employee has a direct effect on the employee’s level of job satisfaction and decision to remain in the organization. Extension agent retention has been shown to increase when a positive relationship and supervisory support exist between an Extension agent and his/her supervisor. Herzberg’s Motivation-Hygiene Theory was used to examine relationships with and impacts of supervisor management on Extension agent job satisfaction. A census of Florida Extension agents were asked to describe their relationships with their County Extension Directors (CED). Significant positive relationships were found between agent job satisfaction and ratings of the hygiene factors of Effective Senior Management and Effective Supervisor. A significant positive relationship was also found between these two hygiene factors. A significant difference was found between effective senior management and the agents’ CEDs gender, with agents with male CEDs reporting higher average levels of satisfaction with Effective Senior Management than agents with female CEDs. Significant differences also existed between agents’ Effective Senior Management satisfaction and years of working relationship between agents and CEDs. Extension supervision and leadership training should be a focus of Extension administration as effective supervision and management have a positive impact on Extension agent job satisfaction.

Automatic fine-grained access control in SCADA by machine learning

The access control is one of the core technique to ensure safety and privacy of the sensing data in information systems. Supervisory control and data acquisition (SCADA) is a very security primitives in control system architecture that are being applied to computers, networked data communications and graphical user interfaces for high-level process supervisory management. SCADA infrastructure which is an essential part of metro systems have been studied by many researchers in recent years. In this paper, We introduce several access control techniques such as Role-Based Access Control (RBAC), Attribute-Based Access Control (ABAC), Fine-Grained Access Control (FGAC). Brief literature review is provided, and possible improvements over the state-of-the-art access control techniques are also proposed. Specially, the machine learning techniques is introduced, which is potential to automate the tedious role engineering process.

Power management and second-order sliding mode control for standalone hybrid wind energy with battery energy storage system

The purpose of this article is to provide a high performance control of a renewable distributed generator to guarantee an electric power quality and jointly reduce the mechanical stress despite any possible uncertainties such as the random nature of wind speed, the presence of parameters uncertainties, and external perturbations acting on the system (sudden load variation). The renewable distributed generator integrating a wind generator associated with a batteries module is considered as an energy storage device and a variable load. The proposed method is designed by a power management supervisor and a sliding mode control technique. First, the power management supervisor is used to monitor the power flows transferred between the different system devices depending on the load variation and on the intermittency of wind production. In fact, it enables to ensure the balance at the continuous, Direct Current (DC) bus between the powers supplied by the renewable distributed generator and those demanded by the load. In addition, it prevents batteries from exceeding its maximum or minimum state of charge ( SOCbat) by keeping it at an acceptable level [30%, 90%]. Second, a second-order sliding mode control based on the super-twisting algorithm is suggested to control the two subsystems (generator side and load side converters). The main target of the first one is to extract the maximum wind power taking into account the parameter variations and the fluctuating nature of wind. The second one is to investigate a second-order sliding mode control of active and reactive load power quantities, which provides better results in terms of attenuation of the harmonics present in the load voltage and current while considering the sudden load variations. In addition, a proportional–integral controller is also designed and simulated to establish a comparison framework. According to the simulation results, the second-order sliding mode control successfully deals with the nonlinearity of the renewable distributed generator compared with the proportional–integral performance.

Article 2: Longitudinal study assessing the one-year effects of supervision performance assessment and recognition strategy (SPARS) to improve medicines management in Uganda health facilities

BackgroundIn late 2010, Uganda introduced a supervision, performance assessment, and recognition strategy (SPARS) to improve staff capacity in medicines management in government and private not-for-profit health facilities. This paper assesses the impact of SPARS in health facilities during their first year of supervision.MethodsSPARS uses health workers trained as Medicines Management Supervisors (MMS) to supervise health facilities and address issues identified through indicatorbased performance assessment in five domains: stock management, storage management, ordering and reporting, prescribing quality, and dispensing quality. We used routine data generated during SPARS visits to 1222 health facilities to evaluate performance changes during the first year of supervision as well as the time until achieving an adequate score in this period. We also explored variables related to facilities, MMS, and intensity of implementation as predictors of performance improvement and time until achieving an adequate score.ResultsHealth facilities received an average of 3.4 MMS visits during the first year of supervision, with an average of 88 days between visits; each MMS implemented a median of 28 visits per year. Overall SPARS scores (maximum of 25) improved by 2.3 points (22.3%) per visit from a mean baseline score of 10.3. The adjusted improvement in overall SPARS score was significantly higher in primary health care facilities (2.36) versus higher-level health facilities and hospitals (2.15) (p = 0.001). The incremental improvement was highest at visit 2, with decreasing but continuing positive gains in subsequent visits. The adjusted mean incremental improvement per visit was highest in the prescribing quality domain, followed by dispensing quality, ordering and reporting, stock management, and storage management. Adjusted improvement in SPARS scores varied by region, year of implementation, and facility ownership. After one year of SPARS, 22% of facilities achieved an adequate score of 18.75 (75% of maximum score).ConclusionsSPARS was effective in building health facility capacity in medicines management, with a median overall improvement of almost 70% during the first year. The greatest improvements occurred in prescribing quality and at lower levels of care, although the highest level of performance was achieved in storage management. We recommend broad dissemination of the SPARS approach in all Ugandan health facilities as well as in other countries seeking a practical strategy to improve medicines management performance.

MEMBANGUN PROFIL RESIKO PADA PEMBUATAN PETA DIGITAL MENGGUNAKAN FRAMEWORK NIST

GPS (Global Positioning System) is the main device that record location based on coordinate . The purpose of location recording is making digital maps and the output are printed-maps. Digital maps and printed-maps that have been authorized by the government will become reference for every activities like terminating the location objects or borderline. The Accuracy and authenticity of coordinate data from GPS is essential for high-accuracy maps, but digital maps are also vulnerable from editing, duplication, or deleted for a particular purpose. Because of that, supervisory management in the manufacturing process is needed to help facilitate in building a digital map-making profile. The reference in managing risk management to build the profile is NIST Framework.

THE OBJECTIVES AND MECHANISMS OF THE AGENCIES OF THE CLUSTER MANAGEMENT TO ENSURE ITS EFFICIENT OPERATION

Purpose:justification of structure of elements and structure of a control system of sectoral-territorial innovative clusters.Methods:article is based on the analysis of the international and domestic experience of creation of control systems of innovative clusters. By her preparation methods of the theoretical, functional and structural analysis and also business simulation are used.Results:following the results of the conducted research it is proved that at creation of a control system of sectoral and territorial innovative clusters (STIC) it is necessary to be guided by three main imperatives. The first consists that if we form a control system of a cluster, then it is necessary and to operate with categories of the theory of management when determining her functions, but not activities of this or that body as it is accepted in domestic practice today. The second consists in need of formal addition of the functions which are carried out by consultative governing body (supervisory board), the providing activity of quick and administrative body of a cluster (management company). And the third in use of design and functional approach to creation of a control system adequate to problems of a cluster.Conclusions and Relevance:STIC control system besides the functions having to management of a cluster direct reference is designed to solve a problem of ensuring interaction of external and internal contours of his business model. For this purpose the recommended structure of a control system, according to results of a research, has to include: The Ministry of Economic Development of the subject of Federation in which the cluster is located; specialized department of Minpromtorg of Russia; this or that state corporation (in case anchor residents of a cluster are its part); general meeting of participants of a cluster; supervisory board and management company. Realization of policy, the strategy and projects directed to formation and strengthening of network interaction of its participants will act as the main form of rendering impact of a control system of a cluster on his development.

Evaluating inter-rater reliability of indicators to assess performance of medicines management in health facilities in Uganda

BackgroundTo build capacity in medicines management, the Uganda Ministry of Health introduced a nationwide supervision, performance assessment and recognition strategy (SPARS) in 2012. Medicines management supervisors (MMS) assess performance using 25 indicators to identify problems, focus supervision, and monitor improvement in medicines stock and storage management, ordering and reporting, and prescribing and dispensing. Although the indicators are well-recognized and used internationally, little was known about the reliability of these indicators. An initial assessment of inter-rater reliability (IRR), which measures agreement among raters (i.e., MMS), showed poor IRR; subsequently, we implemented efforts to improve IRR. The aim of this study was to assess IRR for SPARS indicators at two subsequent time points to determine whether IRR increased following efforts to improve reproducibility.MethodsIRR was assessed in 2011 and again after efforts to improve IRR in 2012 and 2013. Efforts included targeted training, providing detailed guidelines and job aids, and refining indicator definitions and response categories. In the assessments, teams of three MMS measured 24 SPARS indicators in 26 facilities. We calculated IRR as a team agreement score (i.e., percent of the MMS teams in which all three MMS had the same score). Two sample tests for proportions were used to compare IRR scores for each indicator, domain, and overall for the initial assessment and the following two assessments. We also compared the IRR scores for indicators classified as simple (binary) versus complex (multi-component). Logistic regression was used to identify supervisor group characteristics associated with domain-specific and overall IRR scores.ResultsInitially only five (21%) indicators had acceptable reproducibility, defined as an IRR score ≥ 75%. At the initial assessment, prescribing quality indicators had the lowest and stock management indicators had the highest IRR. By the third IRR assessment, 12 (50%) indicators had acceptable reproducibility, and the overall IRR score improved from 57% to 72%. The IRR of simple indicators was consistently higher than that of complex indicators in the three assessment periods. We found no correlation between IRR scores and MMS experience or professional background.ConclusionsAssessments of indicator reproducibility are needed to improve IRR. Using simple indicators is recommended.

A battle of values: a case study of a blacklisted heritage tree represented by European silver fir Abies alba Mill. in a protected landscape in Norway

Old trees in protected landscapes may be historically important, but in some cases problematic if naturalising. In this study, we investigated how a blacklisted heritage tree is valued in a protected landscape, focusing on its cultural history, invasiveness and general management of the area. We used one European silver fir Abies alba Mill. planted in the 1890s as a case-study plant. A historical literary approach included the landscape history, cultural values and introduction history of A. alba. We accessed management information from management plans, botanical reports and the supervisory manager. The present spreading of A. alba was recorded with GPS along transects. In an area constituting approximately 13,600 m2, vegetation clearing and grazing have contributed to limit the invasion of A. alba. Most offspring (88%) were less than 15 cm tall and found within 30 m of the parent in half-shade positions. A. alba belongs to the area’s cultural historical identity, but has attracted more attention as a threat for plant species richness and habitats. Cultural and historical values are generally less prioritised in the management, which is, at present, mainly the responsibility of ecological conservationists. We therefore see a need for interdisciplinary collaboration to equally consider cultural and historical values.

Worlds Collide: Work, Life, and Social Media

While some cases may focus on using social media to advance the interests of a business or brand, this case is best positioned as a springboard for exploring social media as it may coexist with or be embedded in organizational life. The case depicts a challenge for a young direct report, a relatively inexperienced manager, and the manager's supervisor when the direct report reveals a passionate political opinion on Facebook and unwittingly links it to sensitive company information. The case discussion can (1) surface diverse student views on the uses of social media as they relate to work life; (2) encourage analysis of and decision-making in the context of a tricky multilevel managerial situation involving social media use, company nondisclosure policies, and communicating guidelines; and (3) consider how issues raised in the discussion may inform students' own choices as users of social media and as managers of people who use these channels. Larger managerial, organizational, and corporate communication issues that are complicated by employee social media use may arise in this class discussion, including: managing professional boundaries between levels of employees in an organization; the porous boundaries that exist between internal and external communication; and gray areas among private, personal, professional, political, and public speech. Excerpt UVA-BC-0267 Nov. 9, 2018 Worlds Collide: Work, Life, and Social Media Jenny Peters, assistant director of the Schools Assistance Contract at Atek International (Atek), sat at her computer at 8:00 a.m. on a cold Monday morning in February 2017, trying to slow her racing pulse. The prior afternoon, she had checked her Facebook account and discovered one of her direct reports, Richard Harley, had posted some sensitive company information to Facebook over the weekend that his friends, including several people in the company, had seen. Harley had even tagged her in the posts so that they showed up on her Facebook News Feed. She felt awful but didn't know how to respond, or what the consequences would be for herself, Harley, or the company. Peters then logged into her work email and saw a note from her supervisor, Mike Dupree, who said that he had also seen Harley's Facebook posts, and would see her at 10:00 a.m. Monday morning in his office. Peters tried to remain calm, but she had no idea what to do next. Atek International Atek, a government contractor, was cofounded in 1967 by Cal Sullivan, a Korean War veteran, and four former federal government employees. Over time, government contracting became a very lucrative business. By 2017, Atek was publicly traded and boasted 6,000 employees working in over 45 cities around the world and a global headquarters in Northern Virginia. Atek took a broad-brush approach to government support, pursuing contracts in the areas of government, education, energy, health, security, public safety, and social programming. The company provided comprehensive support including program management, business process, data analytics, cybersecurity, strategic planning, marketing strategy, and public relations. . . .

Establishing Tour Guide Work Safety and Risk Management Indicators System

guide is an important part of tourism activities. In this study, senior tour guides, tour guide management supervisors and university tourism management teachers are the subjects of investigation, using literature analysis, in-depth interviews and Delphi research methods. To construct the tour guide work safety and risk management indicator system. The results show that the work safety and risk management indicator system of tour guide leader is divided into three layers, the first layer is the target layer, that is, the ultimate goal of work safety and risk management of tour guide; The second layer is composed of financial risk, personal risk, work risk, service tourist risk, Social psychosocial risk, natural disaster risk, career risk and family support risk. The third layer is the indicator attribute layer, which is composed of 34 items. The results show that work risk and career risk are the most important risk factors for the safety and risk management of tour guides, and the causes are analyzed to provide the reference for the safety assessment and risk aversion of the tourism related management departments and the tour guide.

Research on the reform of curriculum system of health service management

Objective To understand the needs to reform curriculum for the graduate students in health management, and to provide evidence for the reform of the curriculum system. Methods From Jan-uary 2015 to May from China's colleges and universities carrying out health management professional post-graduate education, graduate students and supervisors from 3 universities were selected, and self-designed questionnaires were used to investigate their views on training objectives, abilities and curriculum settings, as well as the needs and suggestions for curriculum reform. The questionnaire survey data were collected and analyzed by SPSS 17.0. Results 120 questionnaires were issued and 100 were recovered in the study, with a recovery rate of 83.3%. 84.0% of the graduate students did not manage relevant work experience before entering the school. The graduate students thought that we should focus on the research and teaching ability training related to the management of health services, and then the cultivation of management ability. There were 60 questionnaires for instructors, and 51 were recovered, with a recovery rate of 85.0%. With regard to the demand for ability training, teachers and graduate students tended to agree on the goal and focus of the training. 100.0% instructors believed that learning was an important course, only 11.2% of the students thought that the course of study was not important, but to the current status of health manage-ment professional postgraduate courses, 79.3% instructors believed that the current curriculum was reason-able, and only 53.5% of the students thought it reasonable. Conclusion The emphasis should be given to optimizing the course setting, adding practical and innovative courses, and strengthening the training of scientific research, etc., which is the only way to improve the quality of health management postgraduate education and meet the needs of health development.

Competency in supportive supervision: a study of public sector medicines management supervisors in Uganda

BackgroundSupportive supervision has been found to be more effective than corrective fault-oriented inspections. Uganda’s Ministry of Health in 2012 implemented a comprehensive strategy (SPARS) to build medicines management capacity in public sector health facilities. The approach includes supportive supervision. This structured observational study assesses supportive supervision competency among medicines management supervisors (MMS).MethodThe study used structured observations of two groups of five purposely selected MMS—one group supervising facilities with greater medicines management improvement during one year of SPARS and one group with less improvement, based on quantitative metrics. We observed and scored behaviors and skills of supervisors in 11 categories deemed critical for effective and supportive supervision.ResultsSupportive supervision was not evenly or adequately implemented, with the median supportive supervision competency score for all observed supervisors being 38%. Supervisors’ main strengths were problem identification, data interpretation, education, and providing constructive feedback (45%–47%). Their weakest areas were assuring continuity and setting targets (17%), and most MMS were fair to strong in effective communication, use of tools, and problem solving. MMS of facilities with little improvement in medicines management over time were weak in setting targets and promoting participation. There was a 33 percentage point difference in the median supportive supervision competency scores between MMS of facilities with more versus less improvement (57%–24%) and a 77 percentage point difference in competency between the highest and lowest scoring MMS (77%–0%). We did not find a relationship between MMS experience (number of visits implemented) and their supportive supervision competency or facility improvement in medicines management. However, there is a likely relationship between supportive supervision competency and facility improvement.ConclusionCompetency of MMS in supportive supervision among the sampled MMS was generally weak, but with much individual variation. Our results suggest that MMS’ supportive supervision competency is positively related to the SPARS effectiveness scores of the facilities they supervise. We recommend strategies to strengthen supportive supervision behaviors and skills.

Enhanced hospital-based learning at a medical school through application of management principles \u2013 a case study

BackgroundA hospital with all its brimming activity constitutes a unique learning environment for medical students. However, to organise high-quality education within this context is a task of great complexity. This paper describes a teaching hospital case, where management principles were applied to enhance the learning quality of medical education.MethodsTraditional attempts from the faculty had been unsuccessful in improving learning among medical students at a teaching hospital. We therefore applied management principles to be able to improve the learning quality. An evaluation was performed from the perspectives of management (course directors/ heads of health care departments), medical students, and physician supervisors. Presages were defined, including educational resources and management; processes were adjusted, including learning activities and staff schedules; and products were assessed.ResultsCharting and benchmarking the use of local educational resources identified unused funding. Structured recurrent collaboration within resource utilization was established between course directors and heads of all concerned health care departments. By formulating a joint agreement, the identified assets were used to reorganise the course, to create constructive alignment, and to increase assigned supervisor time. This resulted in a sustainable improvement of learning quality and culture.ConclusionBy using management principles in combination with a scholarship of teaching and learning, it was possible to locate and redistribute educational resources in an effective way. This improved student learning and the learning culture of the health care departments. We propose that such an initiative could also be transferable to other contexts. Faculty leaders facing similar problems should consider the advantages of a structured collaboration with health care department heads.
