Multinational Military Cooperation in the Global South

In the 21st century, three international military organizations with standing headquarters in the Global South have emerged in the field of military operations. These are the Southern Cross Peace Force in Latin America, the Africa Standby Force, integrating five subregional African forces, and the Peninsula Shield Force in the command structures of the Gulf Cooperation Council countries. This article examines interorganizational differences and similarities in these three important cases, aiming to provide a deeper understanding of their organizational forms within the global diffusion phenomenon of multinational military cooperation. The article uses a novel comparative framework that bridges a gap in systematic studies of multinational military organizations. It aims to provide a gateway for theoretical growth now and for future studies, in the Global South and elsewhere.

A BRIEF OVERVIEW OF BENCHMARKING AS A MANAGEMENT TECHNIQUE IN THE FIELD OF WATER IN ROMANIA

Given the public and permanent nature, of the public utility services, as a continuous operation, coupled with the dynamics of changes in technology, communication, labor market and last but not least the many changes in recent years of legislation and tax regulations in Romania, lead to increased pressure on decision-makers in the field of public utility services with an impact on housing. This topic was chosen in the context of the economic realities in Romania in the field of public utility services with an impact on housing, an area that reflects the ongoing concerns for a development that will ensure technological reform and integration into European financial structures. It is of real interest for any entity in the field of public utility services with an impact on housing concerned about the need to implement a decision-making and financial mechanism that provides a clear and relevant picture of the performance of services provided. In this context, the opinion of the International Water Association Group of Specialists that “benchmarking is a tool for improving performance through systematic research and best practice” has motivated many water companies to introduce benchmarking as a method of management. This article provides an overview of benchmarking as a water management technique for European Benchmarking Co-operation (EBC) compared to the national benchmarking exercise called H2Obenchmark. Due to the fact that both are based on the methodology developed by the International Water Association (IWA), the most important advantage of these benchmarking techniques is that they ensure comparability at any time with any water company in the world that uses the same system. By ensuring the opportunity for knowledge transfer, operators are able to identify and implement best practices and innovative solutions to the realities they face in the field of management, operations and investment projects. The brief diagnosis of water benchmarking in Romania highlights the fact that H2OBenchmark is a mature benchmarking exercise, with experience gained and maintained both in the water sector (ARA, CEB, OR, ANRSC, etc.) and partner consultants.

Exploring the Impact of the Digital Economy on Carbon Emission Efficiency Under Factor Misallocation Constraints: New Insights From China

The digital economy has introduced far-reaching innovations in the fields of government governance, enterprise production, and social operation. How to motivate the economic development mode towards a low-carbon and greenway transformation through the digital economy is a major issue concerning the Chinese government. However, there is scarce evidence to interpret the role mechanism of the digital economy on carbon emission efficiency from the factor misallocation scenario. Taking a database from 30 provincial-level administrative regions for the period from 2011 to 2019 in China as an example, the paper examines the effect of the digital economy on carbon emission efficiency, as well as explores its role mechanism deeply in terms of factor misallocation (capital misallocation and labor misallocation). The results suggest that there is a significant potential for the digital economy to contribute to carbon emission efficiency, as well as this finding, is valid when considering both the endogeneity issue and a series of robustness checks. Also, the digital economy can significantly contribute to carbon efficiency in both southern and northern regions, but more strongly in the northern region. Besides, the digital economy can inhibit the factor misallocation (labor misallocation and capital misallocation) level which ultimately improves carbon emission efficiency. Finally, as a digital economy, it can positively impact carbon efficiency in the long run by mitigating factor misallocation (labor misallocation and capital misallocation).

Risk-bounded and fairness-aware path planning for urban air mobility operations under uncertainty

Collision avoidance is an important issue in the field of the autonomous operations of aerial vehicles in dynamic and uncertain urban environments. This paper introduces a risk-bounded and fairness-aware path planning algorithm for multiple electrical vertical take-off and landing (eVTOL) aircraft operating in such environments. This algorithm advances the sampling-based path planning with the risk domain formulation to generate stochastically safety assured collision-free paths that are robust to both vehicle and environmental obstacle uncertainties for multiple eVTOL aircraft. To address the concern of flight fairness between different eVTOLs in the free flight airspace, the strategy of permit assignment is introduced. By incorporating the risk domain formulation into the sampling-based path planning with the strategy of permit assignment, the algorithm proposed in this paper not only inherits the computational advantage of the sampling-based methods, but also guarantees a stochastically feasible flying zone at every time step. Simulation studies demonstrate the promising performance of the proposed algorithm.

The impact of the relationship commitment and customer integration on supply chain performance

PurposeThis study aims to show how to improve supply chain performance through the relationship between firms and their customers. In doing so, this study examines the impact of a firm’s relationship commitment and customer integration on supply chain performance. The aim is to detail a way to increase supply chain performance through the relationship between companies and their customers.Design/methodology/approachThe empirical analysis was based on a survey on 205 corporate-Egypt multi-industry businesses including manufacturing, retailing, wholesaling and shipping services firms. Data collection was through a questionnaire survey distributed to 1,264 senior managers with responsibilities in the field of supply chain, logistics, purchasing, marketing and operations and with a 16% response rate. A conceptual model was designed, and hypotheses were analysed with covariance-based structural equation modelling.FindingsThis study makes a significant contribution to the supply chain management (SCM) literature by examining the influence of firms’ relationship commitment on supply chain performance in the supply chain management context by means of the disaggregation of customer integration into two dimensions: integration with customer (IWC) and integration by customer (IBC). The findings indicate that firms’ relationship commitment does not relate directly to supply chain performance, but rather indirectly through integration both with and by customers.Research limitations/implicationsThis paper outlines a conceptual model in which firms’ relationship commitment relates indirectly to supply chain performance. The model also sheds light on the fact that IWCs precedes IBCs in supply chains. This finding suggests that firms should focus on customer integration to improve supply chain performance.Practical implicationsThis study offers a particularly refined understanding of the reasons behind and situations in which supply chain integration (SCI) enables firms to gain superior supply chain performance. In fact, firms focusing on customer integration may improve their supply chain performance, thus enhancing the value of the supply chain.Originality/valueThis study contributes to the literature by considering a relational view of the SCI-Performance path. In particular, by disaggregating customer integration into IWCs and IBCs, this paper verifies customer integration acting as a mediator between relationship commitment and supply chain performance in supply chains.

Litteraturvetenskapen i framtiden

Literary Scholarship in the Future: From Canon-Centred Subaltern to Literary-Minded Social Participant Appreciation of literature and literary scholarship has arguably been on the wane in the twenty-first century. In this article, I argue that literary scholarship, in response to this declining interest, needs to be reformed. Literary scholars should continue to study literature from all historical periods, but they need to deal with the conflict between the democratic values of contemporary readers and pre-1968 sexism and racism in literature. This blight on the reading experience cannot be removed by the one-sided measures of historicism or presentism. Rather than marginalizing popular literature, children’s literature, and non-Western literature, scholars should integrate this body of work into the core of literary studies and accord them roughly half of their interest alongside canonized Western literature for adults. Literary scholars should also be prepared to present their teaching curricula as a development of skills that can be used in the processing and evaluation of any kind of text in any kind of employment in a company or a government agency. Furthermore, rather than produce literary readings mainly in terms of content, scholars should highlight the synergy of content and literary qualities such as form, fictionality and generalizability. This will allow them to valorize the enhanced understanding of real-life phenomena offered by literary works in the form of socially useful “applied literary scholarship.” The fields of operation for literary studies should include schools; the training of professionals, such as doctors and economists; and bibliotherapy designed to alleviate anxiety and malaise before it develops into a mental condition requiring treatment in a healthcare system that is already stretched beyond its capacity.

The UN peacekeeping system: from theory to practice

This article examines the key problems of the evolution and functioning of United Nations peacekeeping in the post-bipolar period. On the example of peacekeeping missions after 1990 and key documents in the field of peacekeeping operations, an assessment is given of the challenges facing the UN both at the stage of defining the mandate of operations and in the field of their financing. Based on the position of the United States of America regarding the payment of contributions to the UN budget, the imperfection of the mechanisms for financing UN peacekeeping is demonstrated and the negative consequences for the system of peacekeeping operations as a whole are highlighted. Today, UN peacekeeping is becoming multifunctional, with the main focus gradually shifting to the problems of conflict prevention and peace-building. At the same time, such a change of priorities exposes the problems inherent in the very architecture of UN peacekeeping, primarily related to the definition of the mandate and politicization of the activities of the Secretariat and the financing of missions. In connection with the departure from the traditional function of maintaining the ceasefire, costs are increasing, and non-payment by member countries, such as the United States, of contributions to the budget of operations entails a decrease in their effectiveness. It seems to us that the solution to the above—mentioned problems lies in the continuation of the UN reform process, especially in the field of approving the military part of the mandate and creating a single budget of the OPM integrated into the general UN budget. If there is the political will of the member countries, this process seems to us quite feasible and follows in line with the reform of the UN peacekeeping of the last thirty years.

Development of activity recognition models for mechanical fuel treatments using consumer-grade GNSS-RF devices and lidar

Abstract Mobile technologies are rapidly advancing the field of forest operations and providing opportunities to quantify management tasks in new ways through increased digitalization. For instance, devices equipped with global navigation satellite system and radio frequency transmission (GNSS-RF) enable real-time data collection and sharing of positional data in remote, off-the-grid environments where cellular and internet availability are otherwise inaccessible. In this study, consumer-grade GNSS-RF data were evaluated to determine their effectiveness in developing activity recognition models for excavator-based mastication operations. The ability to automate the classification of cycle elements for operations is valuable for quickly and efficiently quantifying production rates for research and industry applications. The GNSS-RF-based activity recognition model developed successfully classified productive elements versus delay with over 95 per cent accuracy. Individual cycle elements were classified with an overall model accuracy of 73.6 per cent, with individual element classification accuracy ranging from 51.3 per cent for walk/reposition to 95.6 per cent for mastication elements. Reineke’s stand density index, basal area (m2 ha−1) of treated areas and the duration of cycle elements impacted the classification accuracy of the activity recognition model. Impacts of forest stand characteristics on the production rate of mastication treatments were also assessed. Production rates (ha·hr−1) for mastication treatments were affected by the basal area of treated areas. However, the degree to which this would impact operations in practice is minimal. Determining the proper application and capabilities of mobile technologies and remote sensing for quantifying forest operations is valuable in continuing the innovation and advancement of forest digitalization.

Growth Prospects of Franchising Under Current Business Scenario

The article aims to objectively examine the history of Franchising in Europe by focusing on ties between franchisors and franchisees. We also carried out a comprehensive study, interacted with numerous prospective European franchisors and franchisees, and have been in service since 2003. Our results suggest that Europe has a very difficult negotiating franchise agreement. Franchising, which promotes strengthening of mutual links between countries at this point in the history of world economic relations, penetrates virtually every field of economic activities, is thus one of the powerful instruments for the transition to the creative development of the States, thereby ensuring their sustainable development, franchising supports improving trade ties between countries at this point of their growth since, nowadays, this is one of the most efficient and democratic forms of transcending national economies, affecting almost all fields of economic operation. Because of this, it is essential for the research. Comprehensive research of the contradictions in perceptions and real commitments on all sides of the franchising arrangement helps one resolve misunderstandings and remove automated performance ambitions. This article aims to have real consequences for the growth of Franchising in Europe, which will boost the performance and reputation of franchise enterprises by offering a comparative review to a preliminary screening of subjective hypotheses about the advantages of franchising and to suggest incorporating additions and clarity to the partners.

Kategoryzacja w dyskursie zaburzonym – nazwy własne a nazwy pospolite

Aim of the study: the aim of the study was to assess the possibility of making a semantic categorization of common names and proper names by a person diagnosed with appointment aphasia. Method: the study used a case-experimental approach. The results were analyzed qualitatively and quantitatively. Results: the best-preserved semantic relations were indicated, the phenomena proving the quality of access to the mental dictionary were determined, the symptoms of degradation of the semantic dictionary were specified, the stage of processing disturbed was determined. The quantitative evaluation included the percentage description of the obtained results. Conclusions: A generally enhanced ability of the respondent to identify categorical proper names than common names was observed. This can probably be associated with the aforementioned specificity of proper names, related to their information entropy. We can talk about several causes of the observed dysfunctions, the most important seems to be the language deficit, manifested by impaired access to the semantic dictionary, dysfunctions in the field of metalinguistic operations within semantic networks, difficulties with updating words and, to some extent, the depletion of the resources of the mental lexicon. The test results should certainly also be considered in the context of cognitive dysfunctions. The results of this research are in accordance with previous findings suggesting that the difficulty of semantic categorization is related to the dysfunction of semantic memory in the field of categorization of the so-called fuzzy concepts.
