General David H. Berger’s tenure as Commandant of the Marine Corps has set the stage for drastic change toward a Marine Corps more focused on maritime operations. The Commandant has called on these changes to be concept driven and capabilities tested, driving experimentation, wargaming, analysis, research and development, and acquisitions. The Marine Corps is pursuing or developing a number of concepts but lacks an overarching concept that provides context and coherence for conceptual exploration. The author proposes advanced force operations, a concept designed to be broad enough to link together modern concepts like expeditionary advanced base operations and distributed operations, while building on the Marine Corps’ traditions and strengths. Advanced force operations envision Marine Corps forces acting as a vanguard force, competing for maritime access, shaping naval campaigns, and enabling the introduction of Joint forces.

The human factors requirements are discussed in terms of support for individuals in a distributed C2 network and interactions to do collaborative work. PRESTO provides access to an orbiting Global Infosphere, a multi-source, multi-media data base on operational conditions and events. The system should facilitate development of shared situation awareness and coordinated actions. The approach to user interface is a concept of “Active View.” The content of each active view is defined by operational tasks and area of responsibility. The diversity of users requires a diversity of active views, each constructed to fit the characteristics of each application. The challenge to human factors is to develop an architecture of collaborative activities which can be mapped into PRESTO's software architecture and modules. These activities can be divided into single multi-media workstation, individual's active views in integrated multi-media format, collaborative transactions between workstations, and data integration into a shared situational representation. Taxonomies for collaborative behaviors and use of multi-media will have to be developed. An application to Joint Task Force is a probable implementation. The JTF is a distributed command group for rapid deployment and control of interservice forces in crisis management.

Purpose The purpose of this paper is to analyse everyday interactions in a workplace from the point of view of organisational learning, informal learning and peer learning, as well as the possible relationships that can be established between all three. Design/methodology/approach Insights from nine months of ethnographic study provided an operational definition of equality in an organisation, a better understanding of interactions and informal learning between peers, and about psycho-social determining factors or contexts that favour the exchange of knowledge in an organisation. Findings The findings demonstrate the importance of articulating the three elements (organisational learning, informal learning and peer learning) in a joint interpretative framework. With the results generated, it is proposed to move away from the traditional organisational learning based on knowledge and know-how, to a new perspective focused on sharing and participatory opportunities. In other words, without opportunities to participate, without the support and equal access, the fostering of informal learning can be debatable in terms of democracy. Originality/value The results bring the authors closer to being able to design workplace learning strategies that carefully includes the value of participation opportunities and the influence of a dynamic concept of equality. The ethnography in a hospital setting has allowed the authors to gain a better understanding of the contribution of informal learning to the organisation. The focus on the social context and the roles of relationships in informal learning offers new insights into a complex phenomenon.

Interaction model of family planning program management field lines are enhanced as one objective of family planning program revitalization. This research was conducted by exploration activities with qualitative approach (in-depth interviews and group discussion forums) for reconstructing a "model of enhanced interaction". The basic concept of enhanced interaction models are built based on the concept of empowerment, coordination, accompaniment, financing through civil society organizations and the Government of DKI Jakarta. Improvements made to the enhanced interaction models are in the field of family planning services. This study aims to improve the effectiveness of the implementation of the national family planning program and the implementation of the program of economic empowerment of the family in the long-term periods characterized by interaction changes of family planning program management team in the district level and the executive of family planning program in the village level effectively and efficiently. In order to improve the cultivation of family planning program field line, it is necessary to improve the status of Village Family Planning Executive Team to become Village Family Planning Management Team as a more effective management approach. This study recommends that the Government of DKI Jakarta to support operational costs and Activity Groups in RW level. The expected impact is the increase of the proportion of active family planning participants towards PUS in the area of research, especially for pre-prosperous Families and prospreous-I families (Poor). Poor families who join family planning program have the priority access to poverty reduction through economic empowerment of the family planning participants, and it is expected to be implemented in the province of Jakarta.

Knowledge about a wide variety of aspects is fundamental for the safe management and disposal of radioactive waste. This importance of Knowledge Management (KM) is also recognised by EURAD, the European Joint Programme on Radioactive Waste Management (RWM), which brings together over 100 organisations from different countries and backgrounds (Waste Management Organisations, Technical Support Organisations, and Research Entities). This vast resource of expertise and experience feeds into several dedicated EURAD KM programme activities. One of these activities, led by Work Package 11 State-of-Knowledge (WP11 SoK), is capturing experts’ views on the current State-of-Knowledge on topics relevant to RWM and making this knowledge accessible through dedicated documents. For this, EURAD has developed the “Goals Breakdown Structure” (GBS), which provides a framework in which topics are structured thematically, as well as a hierarchy of documents that allows accessing knowledge on different levels of detail (see EURAD Roadmap). To make this knowledge available, EURAD is currently developing a Wiki (i.e., a web-based resource that allows access to knowledge and collaborative interactions) and is drafting a sustainable Knowledge Management System and other supportive KM-IT tools while already feeding the tools with content. This article gives an insight into the general EURAD KM concept, the approaches used, and the results obtained until EURAD’s mid-term, after 2.5 years.

A paradox has been established in the modern healthcare industry - consumers can choose between many alternatives but with high uncertainty, while healthcare establishments have numerous possibilities, but they function in conditions of rigorous demand, globalization and large-scale technological efficiency. This requires a re-evaluation of the classical understanding of competition in value creation - healthcare effects (for patients) and financial gains (for the performance of medical and related activities). Today, competition can be explained as a competition for the creation, supply and realization of healthcare products and related services and goods. It is a dynamic process of competition and, in a more general sense, interaction between competing subjects under conditions of significant state interference. It reflects the modern perceptions of health, the improvement of biotechnology and pharmacy, the changed role of the patients - more and more informed, educated, active and united in thematic groups. For the realization with a focus on personal patient preferences, this embodies the characteristics of the interaction between the healthcare establishment and the patient. Competition integrates business logic and patient thinking. In the context of the concept of joint value creation, it covers the intense interactions between healthcare institutions and the individual. Competition in the healthcare industry is based on dialogue, access, risk assessment and transparency at every stage of value creation and realization. This is realized as a competitive interaction in the environment (network) from the influences of healthcare institutions and other producers of medical and non-medical services and goods, thematic associations and regulations. This is a rivalry in creating and offering healthcare products tailored to individual patient's views, preferences, expectations and financial capabilities. The prospects for a competitive race are a transition from competitiveness to competitive interaction. In parallel with the improvement of the operational efficiency of the medical institution, this imposes, the increasing individualization of the created healthcare products. This requires the development of an environment for shared healthcare experiences with the customer. Thus, the development of competition is connected with the realization of the competitive potential of the healthcare establishment through the prism of patient choice - joint creation of healthcare experience through many channels, through options, through transactions and at an appropriate price-to-experience ratio. Consequently, the competitiveness targeting passive patients in need of treatment is shifted from an effective healthcare establishment-to-patient interaction in order to jointly provide patient satisfaction. Competition is a race between dependant healthcare establishments; it is a rivalry between producers of healthcare effects interacting with patients among many environmental influences. Contemporary competition in the healthcare industry is a mechanism for jointly creating healthcare effects by interaction between a healthcare establishment and a patient with the active role of those in need of treatment. This is realized in the form of competition and co-operation in the course of the creation of individualized healthcare experiences. Competition combines a variety of subjective patient needs, medicinal product characteristics, and network experience qualities. As a guideline for improving competition, we can point to enhancing the quality of the environment, enhancing the possibility to take into account patient need heterogeneity, increasing adaptability to changes in demand, and enhancing capabilities to mobilize all potential competencies.

The need to improve the safety management in the maintenance and operational works on a motorway is a request that all the organizations demand to achieve better goals on safety and in the use of resources. The use of instruments linked to efficiency and effectiveness is one possible solution to this problem. The objective of the present investigation is to prove that it is possible to identify the main activities contained in the A area of an ABC curve and linked to the Pareto´s concepts, defining this way the 20% most dangerous maintenance and operational activities on motorway works. The methodology used was a DELPHI panel formed by experts from different areas linked to safety at work on motorways. The statistic treatment was made through the informatic program IBM SPSS Statistics 24. The results show that it is possible to identify 36 main activities in maintenance and operational works, being relevant the activities related to emergency response, safety guards, expansion joints, provisional signaling and the access to working stations in toll areas. The conclusions of the study reveal that these 36 activities represent the 20% most dangerous activities in maintenance and operational works on a motorway, and show that besides the risks of the work itself, there are four crucial traffic factors to develop a correct risk analysis: weather conditions, traffic characteristics, pavement characteristics and motorway morphologic type.

The article analyzes the domestic legislation on the interaction of state law enforcement agencies and scientific papers on research issues. It is stated that the interaction of law enforcement agencies is to conduct joint activities, joint activities, provides a clear organization and implementation of specific management actions. Such interaction is directly provided by the laws, which determine the legal status of each individual law enforcement agency, and the specific conditions and procedure for interaction are regulated by the relevant joint regulations. The need and expediency of law enforcement cooperation is determined by the fact that such bodies have common specific goals and objectives and are authorized to use state coercion, therefore, the integration of their efforts, capacity, capabilities can significantly increase the effectiveness of crime and systematically ensure law and order. The concept of interaction of state law enforcement agencies is defined as purposeful, coordinated and systematized activities in the field of law and order in the state, the essence of which is to select and apply a set of legal, organizational, operational and tactical and other measures (timely detection, disclosure, suppression and prevention offenses, as well as to eliminate the preconditions and causes of illegal behavior), necessary and sufficient to ensure law and order in the state. Relevant joint activities include: the exchange of information on the fight against crime between law enforcement agencies within their competences and powers; study and dissemination of positive experience of interaction of state law enforcement agencies; creation of joint investigative and operational groups to investigate specific offenses; issuance by law enforcement agencies of joint regulations, instructions, recommendations for standardization and thus increase the effectiveness of their interaction, etc.

AbstractIn the last decade, the world has faced a major change of the security balance, new directions of action being drawn by the main actors of the global scene. States are trying to expand their spheres of influence, to invest in research and technological development, especially to achieve the military superiority in different operational domains, to train their armies following the evolution of the security environment and the changing trends of conducting the armed struggle and to improve their military capabilities to gain or to maintain control over certain areas of interest. This is why, in the last years, the states have invested in military assets that can assure a complete implementation of the anti-access/area denial concept. Starting from the ideas that the A2/AD concept can be applied to all operational environments and that the cyberspace is the fifth domain of the armed struggle, in this paper, after a short glance at the increased interest of three powerful countries in this particular concept, a fastidious excogitation on it will be performed in the second part, while the third part will contain information regarding the cyber operations and their role in implementing the A2/AD concept in the battlefield characterized by 0s and 1s and, lastly, the main objectives of pursuing cyber attacks will be analyzed.

The paper represents the analysis, which has helped to establish the usage of gas hydrate technologies in the methane conversion. This gas could be obtained in different ways. Possibilities and sources for the gas obtaining have been demonstrated. Use of other environmentally friendly sources to support operation in such systems in terms of joint energy complex has been considered. The necessary kinetic connections to provide operational sustainability of all the constituents have been given. The approach helps evaluate quantitatively the priority of its physicochemical transformations to obtain gas hydrates artificially. It is possible to transport methane at considerable distances when it is solidified. Actually, in this case there is no necessity to build costly compressor stations and pipelines for its transportation to consumers. The approach is extremely important for mining regions as it helps prolong the operating period and working out of the abandoned and off-balance coal reserves. In this case, it is proposed to apply special gasification technologies tending to maximum methane recovery. The proposed solutions give the possibility to define the trends of our further research. They will be highlighted in the following authors’ studies.

Operational collaboration in a supply chain is important due to the fierce competition among supply chains. However, the collaboration in a supply chain is often hindered by its distribution channel’s lack of funds. It is of significance to alleviate the capital constraint problem of the distribution channel and explore new joint operational and financial collaboration solutions. In this paper, we focus on exploring the optimal solution of operational collaboration in the presence of manufacturer collateral. We consider a supply chain consisting of a well-capitalized manufacturer and a capital-constrained retailer that faces difficulties obtaining credit from the bank. To help the retailer access financing for a purchase order, the manufacturer promises to pay the lender a proportion of the retailer’s loan if the retailer goes bankrupt. We find that when the bank credit with manufacturer collateral is considered as a mix of trade credit and bank credit, the retailer’s financing equilibrium depending on the maximum wholesale price what the manufacturer can set, can be neither trade credit nor bank credit alone, but a combination of them. Moreover, the retailer’s order quantity and the chain’s operational collaboration level will benefit from the manufacturer collateral.

This article argues that the U.S. Army, rather than the traditional maritime Services, has an emergent opportunity to increase relevancy by exercising sea control to guarantee American access to global markets in competitive spaces in the twenty-first century. In a strategic environment where adversaries are developing sophisticated defenses in-depth to negate American power projection, the institution has a unique capability to create forward positions of advantage with reimagined operational fires commands at scale—as the nucleus of Joint, interagency, and multinational teams—to protect economic prosperity and preserve coalition unity in Central Europe and Southeast Asia in particular, and across the world in general. Advocating for a shift in operational approach that subordinates tactical maneuver in support of operational fires, this article differs from previous scholarship by asserting that the Army should fully embrace sea control, rather than merely providing support to the U.S. Navy and U.S. Marine Corps, to better enable the Joint execution of American and coalition strategies in contested regions.

In the process of the equipments used, operational availability (Ao) is the common top-level parameter for the operational readiness. However, current Ao’s theories and methods toward support objects can mainly be applied to low levels which are lower than basical equipment combat unit, single equipment, but is inapplicable with higher levels such as equipment combat unit and materiel system. Firstly, the paper introduce the concept and usage mission model of the smallest mission unit(SMU). Then research the concept and calculate method of the SMU's operational availability. And research the status update model and simulation flow of accumulation workload time of the SMU in the Joint Operation Equipment Support Simulation and Evaluation System(JOESSES). And simulation calculate of the SMU's Ao. Finally , in the JOESSES ,the method which be created in this paper be proved to be credible and availability.

Abstract. In order to identify holistically better drivetrain concepts for onshore wind turbine application, their operational behavior needs to be considered in an early design phase. In this paper, a validated approach for estimating drivetrain-concept-specific unplanned operational effort and risk based on open-access data is presented. Uncertain influencing factors are described with distribution functions. This way, the poor data availability in the early design phase can be used to give an indication of the concept's choice influence on the unplanned operational wind turbine behavior. In order to obtain representative comparisons, a Monte Carlo method is applied. Technical availability and drivetrain-influenced unplanned operational effort are defined as evaluation criteria. The latter is constituted by labor, material and equipment expenses. By calculating the range of fluctuation in the evaluation criteria mean values, this approach offers an indication of the inherent risk in the operational phase induced by the drivetrain concept choice. This approach demonstrates that open-access data or expert estimations are sufficient for comparing different drivetrain concepts over the operational phase in an early design stage when using the right methodology. The approach is applied on the five most common state-of-the-art drivetrain concepts. The comparison shows that among those concepts the drivetrain concept without a gearbox and with a permanent magnet synchronous generator performs the best in terms of absolute drivetrain-influenced unplanned operational effort over the drivetrain's lifetime as well as in terms of the inherent risk for the assumptions made. It furthermore makes it possible to give insights into how the different drivetrain concepts might perform in future applications in terms of unplanned operational effort. Exemplarily the impacts of higher torque density in gearboxes, a change to moment bearings and adjusted coil design in electrically excited generators have been analyzed. This analysis shows that the superiority of synchronous-generator concepts manifested in historic data is not entirely certain in future applications. Concluding, this approach will help to identify holistically better wind turbine drivetrain concepts by being able to estimate the inherent risks and effort in the operational phase.

The study is aimed at establishing the impact of access to capital, access to markets, access to information and access to technology on competitiveness of smallholder farmers on the market in Ethekwini Metropolitan in South Africa. A questionnaire is used as a research instrument. A total of 100 participants was sampled from a population of 485 smallholder farmers in Ethekwini Metropolitan. From the sample, 21% were male and 79% were female. All respondents were all from the African race. The study reveales that access to funding, access to markets, access to information and access to technology not only influenced viability of the smallholder farmers in Ethekwini Metropolitan, but also that the smallholder farmers were not getting enough access to all four stated variables. Of the 100 farmers, 66% of the smallholder farmers had plots with less than 0.5 acres under cultivation. Another finding was that even though the farmers had basic tools to work with, they required funding to acquire irrigation, water storage facilities, transport and tractors. As far as passing information to farmers is concerned, the farmers mostly preferred extension visits.The study recommends that well equipped agricultural resource centres be established in all the agricultural hubs. It is also recommended that the government employs an asset based community development approach when funding smallholder farmers and that the smallholder farmers and other stakeholders be conscientized on the concept of sustainable farming

The Army Research Laboratory has developed a modeling environment, C3TRACE (Command, Control, and Communication — Techniques for Reliable Assessment of Concept Execution), that aids in the evaluation of different personnel architectures and information technology on system and human performance. This modeling environment, which was originally designed to address tactical command issues, has been applied to a higher level organizational command and control environment within the Joint Forces Command. Specifically, it was applied to an urban operations exercise to evaluate the effect of various personnel structures and communication means on awareness, flow of information, and decision-making.

Much of the internationalisation literature deals with how firms have grown by extending their technologies, brands or organisational structures internationally. These literatures are about firms extending operational territories and gaining access to larger markets. However, in contemporary economies territorial extension is not the only form of internationalisation. Some individuals travel to new countries and see entrepreneurial opportunities. Their contribution to a new or existing venture is "intellect" as part of an internationalisation culture. Somehow, the global environment has changed from a place to be conquered by large corporations to and opportunity-rich environment for sensitive, entrepreneurial participants. The purpose of this exploratory study is to stimulate future research that examines what has changed, in business contexts, structures and markets, and to place intellectual entrepreneurship at the core of the internationalisation discussion.

In large-scale storage system, variety of calculations, transfer, and storage devices both in performance and in characteristics such as reliability, there are physical differences. While operational load data access for storage devices is also not uniform, there is a big difference in space and time. If all the data is stored in the high-performance equipment is unrealistic and unwise. Hierarchical storage concept effectively solves this problem. It is able to monitor the data access loads, and depending on the load and application requirements based on storage resources optimally configure properties [1]. Traditional classification policy is generally against file data, based on frequency of access to files, file IO heat index for classification. This paper embarks from the website user value concept, aiming at the disadvantages of traditional data classification strategy, puts forward the centralized data classification strategy based on user value.

Marine integration with the Navy contributes to meeting vital U.S. naval operational requirements, especially when organized as a Joint Force Maritime Component Command (JFMCC) in the Black Sea against Russian threats. The global operating model addresses integration across escalating levels of competition and conflict called contact, blunt, and surge layers. In the contact layer, Marine integration allows the JFMCC to maintain regional access, assure allies, and counter expanding Russian influence. In the blunt layer, Marine integration supports the JFMCC’s operational objectives of denying Russian sea control and freedom of movement. Finally, in the surge layer, a Navy and Marine integrated JFMCC gains a greater ability to project power against a robust antiaccess and area-denial network and decisively defeat Russian aggression. This article contends that naval integration is also an important component of defense against Russian expansion in the Black Sea region.

This article presents an analysis of the development of the Russian Anti Access/Anti Denial concept – A2/AD. The considerations contained in this article focus on identifying the threats that the Russian A2/AD concept creates for NATO and Poland. This article compiles empirical data from scientific publications, formal strategic and doctrinal documents, which allowed to define the A2/AD category, specify its essence and characterize it through the prism of military and non-military forces and resources engaged by Russia in several important operational regions: the Kaliningrad Oblast, Crimea, Syria and the Arctic.The aim of this article is to evaluate the Russian Anti-Access/Anti Denial concept from the perspective of the threats it creates for NATO and Poland.The obtained research results allow us to make the conclusion that when assessing the current external conditions, effective opposition to the Russian A2/AD by NATO will be very difficult to implement. Increasing the capabilities in this area will probably require the individual member states to increase their defense spending, mainly on the modernization and development of their armed forces. In addition to increasing the financial expenditures, increasing the ability to counteract the Russian A2/AD will require proper coordination and integration of the activities of the entire NATO structure around one coherent operational concept. This applies not only to counteracting the Russian A2/AD in Europe but also in other regions of the world, which in the near future may become the theatre of military operations, both classic, asymmetric or hybrid.

Advanced air mobility (AAM) is a broad concept enabling consumers access to on-demand air mobility, cargo and package delivery, healthcare applications, and emergency services through an integrated and connected multimodal transportation network. While a number of technical and social concerns have been raised about AAM, early use cases for emergency response and aeromedical transport may be key to demonstrating the concept and building public acceptance. Using a five-step multi-method approach consisting of preliminary scoping, modeling performance metrics, developing baseline assumptions, analyzing scenarios, and applying a Monte Carlo sensitivity analysis, this study examines the potential operational and market viability of the air ambulance market using a variety of aircraft and propulsion types. The analysis concludes that electric vertical take-off and land (eVTOL) aircraft could confront a number of operational and economic challenges for aeromedical applications compared to hybrid vertical take-off and land (VTOL) aircraft and rotorcraft. The study finds that technological improvements such as reduced charge times, increased operational range, and battery swapping could make the eVTOL aircraft more reliable and cost-effective for aeromedical transport.

This paper is concerned with the performance analysis of slotted frequency-hopped packet radio networks with Reed-Solomon forward error control coding. Both random and one coincidence frequency hopping patterns are considered. A new concept of the pair-wise hit patterns and the effective multiple-access interference are introduced. The joint probability generating functions of these interference vectors are determined for both synchronous and asynchronous hopping. Closed form expressions for packet capture probabilities and throughput are derived in terms of these joint generating functions. Finally a direct proof is given that hits in different symbols are asymptotically independent.

As the United States faces a rise in credible antiaccess/area-denial (A2/AD) threats, the U.S. Department of Defense (DOD) started developing counteraccess denial strategies early in the twenty-first century. Access denial strategies are not a new defensive strategy; what makes access denial challenging on the modern battlefield is the dramatic improvement and proliferation of weapons capable of denying access to or freedom of action within an operational area. Through a historical review of Japanese naval battles during the early twentieth century, a framework to model possible future contests for control of the maritime domain is possible. Control of the maritime domain is the prerequisite for assured access and sets the condition for successful Joint operations. In this article, recommendations for achieving success in this new operating environment are offered, including investing in low-cost technology that extends ranges of A2/AD capabilities.

V članku se ukvarjamo s konceptom ešaloniranja ognjev. Zmogljivosti sistemov za ognjeno podporo pri majhnih vojskah so omejene, zato je pravilna in smotrna upraba koncepta ešaloniranja ognjev bistvena za uspeh na bojišču. Hkrati pa predvsem manjše članice Nata upravičeno pričakujejo, da bodo v operacijah zavezništva deležne tudi učinkov sistemov združene ognjene podpore, ki jih imajo na voljo velike države. Vnadaljevanju predstavimo koncept ešaloniranja ognjev in njegov vpliv na oblikovanje dobrega sistema ognjene podpore na taktični ravni, od ravni voda do brigade. Nazadnje pa pogledamo na zmogljivosti Slovenske vojske in njenih sistemov za posredne ognje znotraj širšega sistema ognjene podpore Slovenske vojske in združene ognjene podpore zavezništva ter navedemo nekaj ključnih ugotovitev, ki bi lahko služile kot premislek pri nadaljnji gradnji zmogljivosti Slovenske vojske. The article discusses the concept of echelonment of fires. Small armed forces such as the Slovenian Armed Forces (SAF) have a limited joint fires capability. Therefore, in order to succeed on the battlefield, they have to correctly apply the principles of echelonment of fires. Additionally, smaller NATO members rightfully expect to receive some of the Joint Fires Effects from larger member armies in the Joint Operational Environment. The article looks at the Joint Fire Support and indirect fire systems, and what the terms mean for small NATO member states with limited capabilities. It then goes on to present the concept of echelonment of fires and some key terms within the concept. Lastly, it looks at SAF capabilities through the echelonment of fires concept and Indirect Fire Systems. The author also puts forward some suggestions for future development of SAF capabilities.

In recent years, electric vehicles have been widely promoted by virtue of environmental protection and pollution-free advantages. In the future, they are expected to become a mainstream means of transportation. However, as new services and business models become more and more closely related to the distribution network, the traditional AC distribution district has limited ability to respond to the large-scale access of electric vehicles. Therefore, it is becoming increasingly important to improve the ability to respond to electric vehicle access, reduce the negative impact of large-scale electric vehicle access on the grid, and predict and calculate the uncertainty caused by electric vehicle load access. Therefore, this paper proposes the concept of flexible distribution district, constructs the security operational boundary model for flexible distribution district, and uses “security margin percentage” as the measurement mechanism to provide dispatchers with an intuitive system operating status. In addition, this paper also proposes an effective uncertainty quantification method for the problem that it is difficult to measure the changes of bus voltage and line current at network nodes when large-scale electric vehicles are connected to the network. Numerical results demonstrate both the extensibility and the practicality of the proposed security operational boundary. In addition, the proposed uncertainty quantification method can reflect the impact of load changes on the characteristics of the power grid, which is helpful to study the improvement significance of adjusting electric vehicle load changes to distribution network optimization.

This paper presents a new chain coordination model for quality management strategies of European pork supply chains. It is a result of qualitative research into intensive and extensive pork production in seven selected countries consisting of a literature review, country-specific expert interviews and case studies. The model defines strategic roles and responsibilities for quality management actors on normative, strategic and operational levels and groups these actors into the categories certification, coordination and control. New actors have been defined for the category 'coordination of quality management strategies': the chain quality board (normative), the network coordinator (strategic) and the quality broker (operational level). The proposed concept of a quality broker represents an innovative approach to facilitate implementation of coordination mechanisms in pork supply chains. In addition, coordination mechanisms have been defined and classified under the headings contracts, information technology, information sharing and joint decision making. The model represents an organizational concept applicable to a broad diversity of pork supply chains. It is intended to facilitate the establishment and management of quality management strategies to strengthen the competitiveness of European pork producers.

Abstract Suborbital platforms are one of alternatives for satellites. They offer cheaper access to space to perform broad range of scientific and technology R&D. One of suborbital platforms are sounding rockets, which are suitable for these applications. A concept of scientific mission utilizing the sounding rocket is presented by author in this paper. The novelty of this mission is the operational responsive launch approach, which presents the example of the mission which responds for payload user needs, not payload contest approach, which is often in scientific community competing for payload space in space agency sounding rocket launch campaigns. The main mission goal is to perform astronomical observation of NEO using IR/VIS telescope. The secondary goal is to qualify the instrument for use on astronomical satellite observatory and raise its technology readiness level from TRL 6 to TRL 8. The expected mission output is to gain scientific data on NEO object and perform new IR/VIS optoelectronic instrument technology validation.

The author of the article reveals the socio-legal conditionality of implementation of interaction between the bodies of pre-trial proceedings in the activity of disclosing and investigating committed crimes. The urgency of studying the essence and meaning of this interaction is substantiated. The concept of interaction is considered from the point of view of different branches of knowledge. The opinions and views of domestic and foreign scientists regarding the concept and meaning of interaction, both a social phenomenon and a legal category, implying conscious, coordinated, joint and purposeful actions of bodies of pre-trial proceedings are analyzed. The author’s definition of the concept of interaction between the bodies of pre-trial proceedings is given. The author states the unsatisfactory state of interaction of the bodies of pre-trial proceedings, in particular, interrogators, investigators with the bodies carrying out pre-investigation checks and operational-search activity based on the sociological studies carried out on organization of activities for the disclosure, investigation of crimes and the search for persons hiding from the court and investigation. The author sees the solution to these problems in strengthening the effective measures of law enforcement agencies in combating crime, active and effective use of possibilities of criminal procedural and operational search activities.

A vessel convoy is a complex and high-risk operation completed during icebreaking operations in the Arctic. Icebreaker navigators need to continuously communicate with their crew while monitoring information such as speed, heading, and distance between vessels in the convoy. This paper presents an augmented reality user interface concept, which aims to support navigators by improving oversight and safety during convoy operations. The concept demonstrates how augmented reality can help to realize a situated user interface that adapts to user’s physical and operational contexts. The concept was developed through a human-centered design process and tested through a virtual reality simulator in a usability study involving seven mariners. The results suggest that augmented reality has the potential to improve the safety of convoy operations by integrating distributed information with heads-up access to operation-critical information. However, the user interface concept is still novel, and further work is needed to develop the concept and safely integrate augmented reality into maritime operations.

Abstract Introduction It is critical for the U.S. Army Medical Department to acknowledge the distinctive medical needs of soldiers and conceptualize soldier-centered care as a unique concept. In addition to the nationally recognized standards of patient-centered care, soldier-centered care includes provisions for the priorities of soldier health and wellness, injury prevention, illness and injury management, and the preservation of physical performance and medical readiness. The development of soldier-centered care as a distinctive concept may strengthen the evidence base for interventions that support improvements to soldier care and thus, enhance health outcomes specific to soldiers. The purpose of this article is to analyze the concept of soldier-centered care, clarify the meaning of soldier-centered care, and propose a theoretical definition. Methods Rodgers’ evolutionary concept analysis method was used to search and analyze the literature for related terms, attributes, antecedents, and consequences and to create a theoretical definition for soldier-centered care. Results The results of this concept analysis indicated that soldier-centered care is realized through the presence of nine attributes: operational alignment of care, provider and support staff therapeutic competence, management of transitions and care coordination, technology and accessibility, management of limited and lost work days, trust and expectation management, leadership support, continuity, and access to care. Soldier-centered care is focused on health and wellness promotion, disease and injury prevention, and early diagnosis and treatment of acute injuries in the primary care setting to facilitate timely injury recovery, reduce reinjury, and prevent long-term disabilities. The result of soldier-centered care is enhanced physical performance, medical readiness, and deployability for soldiers. Based on the literature analysis, the following theoretical definition of soldier-centered care is proposed: Soldier-centered care is individualized, comprehensive healthcare tailored to the soldier’s unique medical needs delivered by a care team of competent primary care providers and support staff who prioritize trust and expectation management, operational alignment of care, leadership support, care coordination, and the management of limited and lost workdays through the use of evidence-based practice approaches that employ innovative information technology to balance access to care and continuity. Conclusions The concept of soldier-centered care often emerges in discussions about optimal physical performance and medical readiness for soldiers. Although soldier-centered care and patient-centered care have similar conceptual underpinning, it is important to clarify the unique physical and medical requirements for soldiers that differentiate soldier-centered care from patient-centered care. Implementing the defining attributes of soldier-centered care in the U.S. Army primary care setting may improve the quality of care and health outcomes for soldiers. When defining performance metrics for primary care models of care, the U.S. Army Medical Department must consider assessing outcomes specific to the soldier population. Developing empirical indicators for the attributes of soldier-centered care will support meaningful testing of the concept.

Maritime user interfaces for ships’ bridges are highly dependent on the context in which they are used, and rich maritime context is difficult to recreate in the early stages of user-centered design processes. Operations in Arctic waters where crews are faced with extreme environmental conditions, technology limitations and a lack of accurate navigational information further increase this challenge. There is a lack of research supporting the user-centered design of workplaces for hazardous Arctic operations. To meet this challenge, this paper reports on the process of developing virtual reality-reconstructed operational scenarios to connect stakeholders, end-users, designers, and human factors specialists in a joint process. This paper explores how virtual reality-reconstructed operational scenarios can be used as a tool both for concept development and user testing. Three operational scenarios were developed, implemented in a full mission bridge simulator, recreated in virtual reality (VR), and finally tested on navigators (end-users). Qualitative data were captured throughout the design process and user-testing, resulting in a thematic analysis that identified common themes reflecting the experiences gained throughout this process. In conclusion, we argue that operational scenarios, rendered in immersive media such as VR, may be an important and reusable asset when supporting maritime design processes and in maritime training and education.

Along urban and suburban arterials, closely-spaced signalized intersections are commonly used to provide access to adjacent commercial developments. Often, these signalized intersections are designed to provide full access to developments on both sides of the arterial and permit through, left-turn, and right-turn movements from every intersection approach. Traffic signal timing is optimized to reduce vehicle delay or provide progression to vehicles on the arterial, or both. However, meeting both of these criteria can be cumbersome, if not impossible, under high-demand situations. This research proposes a new design that consolidates common movements at three consecutive signalized intersections into strategic fixed locations along the arterial. The consolidation of common movements allows the intersections to cycle between only two critical phases, which, in turn, promotes shorter cycle lengths, lower delay, and better progression. This research tested the consolidated intersection concept by modeling a real-world site in microsimulation software and obtaining values for delay and travel time for multiple vehicle paths along the corridor and adjacent commercial developments in both existing and proposed conditions. With the exception of unsignalized right turns at the periphery of the study area, all non-displaced routes showed a reduction in travel time and delay. Additional research is needed to understand how additional travel through the commercial developments adjacent to the arterial may effect travel time and delay. Other expected benefits of the proposed design include a major reduction in conflict points, shorter pedestrian crossing and wait times, and the opportunity to provide pedestrian refuge areas in the median.

Evolving computing technologies such as cloud, edge computing, and the Internet of Things (IoT) are creating a more complex, dispersed, and dynamic enterprise operational environment. New security enterprise architectures such as those based on the concept of Zero Trust (ZT) are emerging to meet the challenges posed by these changes. ZT systems treat internal and external networks as untrusted and subject both to the same security checking and control to prevent data breaches and limit internal lateral movement. Context awareness is a notion from the field of ubiquitous computing that is used to capture and react to the situation of an entity, based on the dynamics of a particular application or system context. The idea has been incorporated into several access control models. However, the overlap between context-aware access control and zero-trust security has not been fully explored. In this SoK, we conduct a systematic examination of ZT, context awareness, and risk-based access control to explore the critical elements of each and to identify areas of overlap and synergy to enhance the operation and deployment of ZT systems.

Limited access to affordable and decent housing for the low-medium income households of Namibia, especially in Windhoek, is a major concern. This is evident as nearly 70 percent of the population are unable to access affordable housing. This situation is exacerbated by lack of an integrated framework for affordable housing delivery strategy. Adopting an interpretivist perspective, in depth literature review of published records, and using hybrid value chain model; this paper aims to identify an effective and efficient strategy for the delivery of affordable housing in Windhoek through the application of the stakeholder approach. Also, the paper intends to determine the appropriate division of roles between public, private and community institutions, and to suggest possible policy interventions necessary for a viable affordable housing delivery strategy. Though several non-integrated initiatives are operational in Windhoek, the joint Public-Private-Social-Sector Partnership model represents a new business model in the affordable housing sector.

The modern “Anti-Access/Area Denial” A2/AD systems are defined as a combination of all possible measures that can limit the ability of a potential opponent to enter and occupy a given area (operational theatre). Their action relies, among others, on radio-electronic disruption of digital guidance systems, communication, command and control systems, shooting down long-range maneuvering missiles, drones, and aircraft. The primary assumption of the anti-access concept is to deprive the enemy of the possibility of entering a given operational area (A2 – Anti-Access) through long-range destruction and depriving them of freedom of action in that theatre (AD – Area-Denial) by medium and short-range weapons. The Surface-to-Air Missiles (SAM), Anti-Ship Ballistic Missiles (ASBM), and Anti-Ship Manoeuvring Cruise Missile (ASCM) are used to carry out A2/AD tasks. Field artillery has also been used recently, particularly the Long-Range Precision Fires (LRPF). The purpose of the article is to determine the chance of using field artillery against the A2/AD systems. According to the authors, the NATO forces will lose control in the air in the first period of the conventional conflict with an equivalent opponent, and its rapid recovery will be a priority. Field artillery, as a weapon with ever greater possibilities of precise and deep destruction, can become a decisive factor, allowing dominance of A2/AD systems and enabling the implementation of tasks of its air-force and army aviation, as well as ground forces.

The legal concept of the employer plays an increasingly important and contested role in the modern economic context of broad-sweeping organizational fissuring. This article focuses on the role of employer concepts specifically in the collective bargaining domain, where they hold the unique potential to substantially affect access to regulated collective bargaining, its efficacy, and the extent of worker bargaining power. Building on a critical engagement with previous normative literature on fissuring and on the concept of the employer, the paper examines the interaction of fissuring and employer concepts in the context of the US and Canadian ‘Wagnerist’ collective bargaining regimes, and compares the trajectory of employer concept doctrine in each of these two countries in recent decades. The comparative analysis suggests that while employer concept reform within collective bargaining regimes remains constrained in important respects in both the US and Canada, these concepts have also recently diverged in important formal respects shaping their effects in fissured contexts. This divergence is comprised of a formal expansion of their scope in Canada; a narrowing of their scope in the US; and an effective inversion of the US joint employer concept consequentially into less of a remedial, and a more restrictive device. As a heuristic, comparison of US developments with those in its neighbour’s regime that has much else in common, help to highlight the extraordinarily restrictive nature of most recent US doctrine, including the 2020 National Labor Relations Board (NLRB) final rule on joint employer status, its facilitation of fissuring, and the formidable task confronting US labour of somehow bringing lead firms into the regulated collective bargaining process.

Advances on differentiating between malicious intent and natural “organizational evolution” to explain observed anomalies in operational workplace patterns suggest benefit from evaluating collective behaviors observed in the facilities to improve insider threat detection and mitigation (ITDM). Advances in artificial neural networks (ANN) provide more robust pathways for capturing, analyzing, and collating disparate data signals into quantitative descriptions of operational workplace patterns. In response, a joint study by Sandia National Laboratories and the University of Texas at Austin explored the effectiveness of commercial artificial neural network (ANN) software to improve ITDM. This research demonstrates the benefit of learning patterns of organizational behaviors, detecting off-normal (or anomalous) deviations from these patterns, and alerting when certain types, frequencies, or quantities of deviations emerge for improving ITDM. Evaluating nearly 33,000 access control data points and over 1,600 intrusion sensor data points collected over a nearly twelve-month period, this study's results demonstrated the ANN could recognize operational patterns at the Nuclear Engineering Teaching Laboratory (NETL) and detect off-normal behaviors—suggesting that ANNs can be used to support a data-analytic approach to ITDM. Several representative experiments were conducted to further evaluate these conclusions, with the resultant insights supporting collective behavior-based analytical approaches to quantitatively describe insider threat detection and mitigation.

This paper presents a concept and implementation of a toolbox for design and application of tripod-based parallel kinematic machines (PKMs). The toolbox is a suite of design tools to support users from conceptual design to actual application of tripod-based PKMs. These design tools have been individually developed in different languages and development environments, and are integrated seamlessly using a JAVA-based platform. Users can access all the design tools through a friendly graphical user interface (GUI). It is the first computer-aided design system specially developed for tripod-based PKMs. The toolbox includes some innovative methodologies, such as a forward kinematics solver, the concept of joint workspace, on-line monitoring based on forward kinematics, and the concept of motion purity. The paper gives an overview on the toolbox architecture and some key technologies.

There has been significant interest and activity in shared-use vehicle systems as an innovative mobility solution. Shared-use vehicle systems, that is, carsharing and station cars, consist of a fleet of vehicles used by several different individuals throughout the day. Shared-use vehicles offer the convenience of a private automobile and more flexibility than public transportation alone. From the 1990s to today, varying degrees of intelligent transportation system technologies have been applied to shared-used systems, providing better manageability and customer service. Many shared-use vehicle service providers today include some degree of advanced technologies (online reservations, vehicle tracking, smart card access) in their operations. Currently, there is a developing need for interoperability among shared-use vehicle service providers (e.g., smart card access among carsharing organizations) and transit operators (e.g., transit fare collection via smart cards). Interoperability will likely result in higher customer satisfaction and use, leading to greater market penetration. Similarly, some standardization will likely unfold for overall operational techniques (online reservations and insurance policies), customer interactions, and to some degree vehicle interfaces. Because shared-use vehicles systems are still a relatively new mobility concept, an industrywide standardization approach is still premature. Nevertheless, there are attempts to identify many of the important issues that will play a significant role in interoperability discussions among shared-use vehicle providers and the development of industry standards in the future. There are key elements in intelligent shared-use vehicle system operations and trade-offs encountered during the pioneering stage of shared-use vehicle system developments. Topics to discuss include vehicles, user–system interactions, user–vehicle interactions, and system operations.

The Sriwijaya Air airline is collaborating with five strategic partners under the auspices of Garuda Indonesia. This was realized in the form of a joint operation carried out by PT Citilink Indonesia with PT Sriwijaya Air and PT NAM Air where the collaboration ended on 31 October 2019 and left a trail of debts and debts. The importance of paying more serious attention to the treatment and process of operational cooperation (Joint Operations), in order to realize good corporate governance from the process of inquiry in the implementation of a merger or acquisition which is referred to as due diligence. In this study, researchers used a qualitative phenomenological approach. Phenomenology is an approach that focuses more on the concept of a particular phenomenon and the form of the study is to see and understand the meaning of an experience related to a particular phenomenon. The two companies are cooperating in Non-Administrative joint operation or there are no separate business entities from the two companies. In practice, the joint operation organizes its own special bookkeeping. Project Owner Bill submitted and agreed by each member of the joint operation, for Commercial Invoice, Tax Invoice, and proof of income tax article 23 to be on behalf of the company of the party organizing the joint operation bookkeeping. Along with the fulfillment of its VAT obligations, it is the responsibility of the party organizing the joint operation books.
