Authors: Wei Ren-jie , Wu Xiao-lin , Xia Feng , Chen Jing-cao 
Published: September 2022

BackgroundAlthough the incidence of a single meningioma or a single aneurysm is common, cases of multiple meningiomas combined with multiple aneurysms are rarely reported, and surgical treatment of the coexisting situation is also relatively uncommon.Case presentationA 38-year-old male patient presented to the neurosurgery department of our center with a headache. Examination revealed only symptoms of headache. Laboratory tests showed only decreased total protein and albumin. Magnetic resonance imaging showed preoccupation with the frontal lobe and the right temple bone. Magnetic resonance angiography and digital subtraction angiography showed two aneurysms in the anterior communicating artery and right anterior cerebral artery. Based on a combination of the patient’s history and imaging, we hypothesized that the patient was simultaneously suffering from meningioma and an aneurysm, and both of them are multiple. The patient underwent tumor resection and clipping procedure based on this hypothesis in one surgery. Intraoperative biopsy proved to be a meningioma. The patient was discharged on the 10th postoperative day, and a postoperative follow-up suggested no complications.ConclusionMultiple meningiomas combined with multiple aneurysms are rare to be reported in the same patient. For those unruptured intracranial aneurysms (UIAs) located in the visual field of craniotomy prepared for brain tumorlike meningioma, it is possible to do the clipping as well. When the meningiomas are multiple, fitted with the surgical indication, and located in a position that cannot be treated in one surgery, this may lead to a two-stage operation, no matter where the UIAs are located.

Published: September 2022

The frequency and severity of crises and disasters in recent years has highlighted the need and urgency of studying ways to mitigate the impact of these phenomena. These have been overwhelming for businesses with very large impacts on the economies of the countries. It is a complex phenomenon, widely confirmed in the literature, where a variety of studies point to strategic capacity and business model design as key factors for business resilience. The ability to design products or services and deliver them competitively in the market requires a clear strategic definition, as well as the design, implementation, and management of new business models.
The wine sector also suffered major impacts during the pandemic crisis, especially in 2020, however its recovery shows the resilience of this entrepreneurial sector. During this crisis, many business models proved to be obsolete, but others have shown great resilience, proving that it is possible to resist and even thrive in a crisis context. On the other hand, in a globalized market, intense competition in the wine sector leads to critical management issues for wine producers. Due to the unique characteristics of the product, entrepreneurs, and managers, in this sector, need to critically review their business models, establish strategies, and measure their performance.
Considering the crisis on business wine sector caused by pandemic situation, this study aims to answer the questions “What strategies have been implemented in the wine sector of Setúbal Peninsula that have contributed to the survival and prosperity of the sector?”; Is there an ideal business model for this sector on the Setúbal Peninsula?”
The aim of this study is to identify successful strategies of wine sector in a context of crise as well as propose a robust business model for wine sector in Setúbal Peninsula. Both quantitative (questionnaires) and qualitative methods (focus group) were used.
As result of the research, we highlight the identification of some competitive behaviors that may contribute to suggest possible critical success factors in the business models of the Portuguese wine sector.
Innovation in the circular economy
Authors: Blažek Lukáš 
Published: September 2022

The circular economy (CE) is an area that is increasingly resonating across different sectors. This is one of the principles of the sustainability strategy. CE deals with ways to improve the quality of the environment and human life by increasing production efficiency. In the future, it is intended to replace the linear economy, in which a large percentage of products, in the first place, end up unnecessarily after consumption in landfills or incinerators. It is necessary to deal with the observance of the principles of the circular economy, mainly for the sake of nature protection in connection with the visibly changing climate and stocks of raw materials. In the context of global trends, sustainability strategies are a necessity for more and more companies. It is therefore a presentation of the concept of environmentally sustainable economy, technology and production chain in today's globally burdened environment.
Accessing CE in terms of cost, material and energy savings can be a great motivation for companies. Companies are trying to reduce costs associated with production and waste management and are looking for new business models. As part of the transition from linear to CE principles, procedures and opportunities for a step improvement compared to the existing competition in the form of the implementation of innovative proposals can be recommended.
There are not only ecological but also economic arguments in favor of CE. The economy requires resources to produce goods and services and ultimately to create value for society. Unless companies radically use recyclable materials more often and adhere to CE principles, they will face a shortage of resources that will complicate their operations in the medium to long term.
In order for companies to become part of the circular economy, they must carry out a complete overhaul of their business models. Based on analyzes of the economic and social environment, the presented article provides an overview of the possibilities of innovation and eco-innovation within CE. The subject was to determine the development of the implementation of innovations in CE in today's society, as one of the latest approaches to the production, consumption and subsequent processing of waste.
Assessment Dimensions and Items for the Evaluation of the Technological Maturity of Applied R&D Organizations
Authors: Hecklau Fabian , Kidschun Florian , Kohl Holger 
Published: September 2022

Applied research and development (R&D) organizations strive to develop technological solutions that translate results from research and science into state-of-the-art products and services. This can only be achieved when technological resources and competences are effectively and efficiently used to build up competitive advantages. Therefore, the assessment of the technological capability can provide applied R&D organizations with information on strengths and weaknesses in their specific technology areas, on the basis of which technology strategies can be derived to contribute to the development and training of substantial (core) competences, which in turn improve the quality of unique and differentiating products and services. In this context, the main aim of this paper is to describe crucial assessment dimensions and the respective items within those dimensions. Therefore, it must be focused on the technology basis of the applied R&D organization to identify important evaluation items. The technological base serves as input, as both technologies and competencies that are used for the execution of R&D activities need to be analyzed and evaluated. Additionally, the results of the R&D activities need to be focused as outputs. In this regard, technologies that result in products or technological services need to be considered. Lastly, assessment items in the field of cooperation must be taken into account as technological synergies through partnerships are important success factors for R&D organizations. In this context, partners who support the execution of R&D activities must be focused.
Shared Stressors and Stress Coping Strategies in Start-up Teams
Authors: Gapeyeva-Yukce Liudmila , Saukkonen Juha , Kautto Henna 
Published: September 2022

Engaging in new entrepreneurial efforts sets many demands for individuals involved, and many of those demands impact the well-being of the people in a start-up company. One common issue linked to well-being is stress. Prior research has indicated that a majority of all entrepreneurs experience stress on a regular basis (e.g. Shepherd et al., 2010). Furthermore, a recent study by Wach et al. (2021) identified that entrepreneurial stress differs from the stress that salaried employees with no entrepreneurship responsibility face in their work. The “overall high and persistence level of stress” (Wach et al., 2021) calls for stress research focusing on entrepreneurial setup. Since entrepreneurship is a wide concept and entrepreneurs as a category includes a wide variety of entrepreneurial individuals and teams, an even tighter scoping of stress research is defendable.
This study studied a sub-category of entrepreneurial organizations called early-stage start-ups. This cohort of companies faces lots of uncertainties concerning the market, technology, and competition. Thus, it can be logically argued that these companies have stressors that are typical to their stage of development as well as difficult to solve due to the scarce resources that a young start-up possesses.
The research design adopted was based on treating entrepreneurial stress as a collective effort as well as putting emphasis on the dynamic and volatile nature of the presence of stress in daily start-up operations. The longitudinal approach (study period of 3 weeks) and team-based fresh (video) entries by the teams (4 start-up teams of 2 to 5 people each) were tackling some of the methodological challenges of prior research. Both the experienced stressors and the coping strategies used got recorded and subjected to thematic content analysis. The findings identified stress-related characteristics typical for team-based operating model and also communal coping strategies including those that are rarely reported in the studies of coping strategies on the individual level. The findings contribute academically to the theory-building on the well-being of entrepreneurs and on a pragmatic level for entrepreneurs acting in their typically stress-laden environment as well as for the support and educational organizations for entrepreneurship.

Redes de sociabilidad, supervivencia y trabajo intelectual: el rol de CLACSO y su boletín David y Goliath durante la última dictadura argentina
Authors: Rodríguez Martha 
Published: September 2022

Las dictaduras que asolaron a la Argentina durante las décadas de los sesenta y setenta, produjeron una reestructuración profunda de las universidades y del sistema de investigación científico y tecnológico. Diezmadas en sus actividades de investigación y docencia, las instituciones públicas sufrieron la obturación de sus espacios académicos, el desfinanciamiento y la persecución ideológica.En contraste con este panorama que caracterizó a gran parte del medio académico público, se desarrollaron durante los años sesenta ―y con mayor impulso desde mediados de la década del setenta― una apreciable cantidad de instituciones privadas dedicadas a la investigación en ciencias sociales. Estas se convertirían en una alternativa frente a la extrema inestabilidad y represión del ámbito público. La mayoría de estos centros funcionaron como una suerte de refugio intelectual; allí se cobijaron un número no desdeñable de economistas, sociólogos, politólogos e historiadores que encontraron un espacio de protección y relativa autonomía. Este fenómeno propició cambios en las formas de hacer ciencias sociales en la región, aperturas temáticas, teóricas y metodológicas, así como diálogos fluidos con otros contextos nacionales.El Consejo Latinoamericano de Ciencias Sociales (CLACSO), cuya Secretaría Ejecutiva funcionó siempre en Buenos Aires, se destacó dentro de estas instituciones por su multimplantación a nivel regional, por su fortaleza institucional y la de varios de sus centros-miembros, por la capacidad de financiamiento, así como por la protección recibida de organismos y agencias internacionales. A lo largo de este artículo analizaremos las actividades desarrolladas por clacso durante la última dictadura en la Argentina (1976-1983). Lo haremos a partir del estudio de su publicación David y Goliath. Boletín CLACSO, fuente principal de nuestra investigación. Ella se convirtió rápidamente en el vocero principal de las actividades, así como en un espacio de difusión, análisis crítico y coordinación entre intelectuales latinoamericanos.

Published: September 2022

<p> Microgrids specialized for tactical operations have been subjected to several challenges. These tactical power networks are islanded and have a relatively low power generation capacity. Meeting power requirements of military equipment, having intermittent and highly inductive nature, exposes microgrids to severe stresses. Existing methodologies to monitor and control the impact of load variations require sophisticated equipment and trained personnel. The objective of this research paper is to present an open-source edge energy monitoring system (EEMS) for efficient demand management of tactical networks. The proposed system is capable of capturing all minute operational artifacts, including harmonic distortions and power quality of these networks. A variable gain amplifier circuit enables the proposed EMS to sense all the signals in a wide range of power with higher resolution. The proposed system utilizes raspberry pi as an edge device to meet the low power requirements of tactical networks. The novel concurrent programming approach adopted in the proposed EMS, effectively handles the large amount of data acquired from the network. This parallel processing of acquired data speeds up the execution process. All electrical parameters obtained during this process are stored in an encrypted local database that can be utilized for fault analysis and load prediction. Further integration of machine learning tools in proposed EMS assists in automated power network reconfiguration and tuning under harsh battlefield situations </p>
