Metodyki zarządzania projektami w parkach naukowo-technologicznych. Wyniki badań własnych
Authors: Wysmyk Przemysław
Published: January 2021

Przedmiot badań: Przedmiotem zainteresowania jest obszar zarządzania projektami przez parki naukowo-technologiczne w Polsce, w tym finansowanymi ze środków publicznych. Parki dotych­czas były badane raczej w kontekście uwarunkowań historycznych ich funkcjonowania, charak­terystyki i efektywności świadczonych usług oraz w aspekcie makroekonomicznym w szczegól­ności w połączeniu z oceną wpływu interwencji publicznej środkami finansowymi UE, aniżeli w obszarze zarządzania projektami i odpowiadających im metodyk. W artykule dokonano analizy pojęciowej i funkcjonalnej parków jako instytucji otoczenia biznesu. Zaprezentowano wyniki badań empirycznych dotyczących identyfikacji stosowanych w parkach metodyk zarządzania projektami. Wskazano trzy modele służące do oceny organizacji pod kątem doboru optymal­nej metodyki zarządzania projektami. Rezultaty badań mogą okazać się przydatne dla praktyki zarządzania projektami przez parki stanowiące element systemu innowacji w polityce rozwoju regionalnego w procesie dalszej ich profesjonalizacji.

Cel badawczy: Przedstawienie dominującej metodyki zarządzania projektami w parkach nauko­wo-technologicznych stanowiących ośrodki innowacji w Polsce, a także wyjaśnienie wpływu na sposób zarządzania projektami (zmianą) w organizacji takich parametrów, jak kultura organiza­cyjna, zespoły oraz rodzaj projektów. Istotnym zagadnieniem wydaje się kwestia, w jaki sposób i jakim zestandaryzowanym narzędziem, bez względu na indywidualne cechy organizacji, można badać przyjęte w parkach metodyki i podejścia do zarządzania projektami wpływające na sku­teczność i efektywność funkcjonowania całej organizacji. 1

Metoda badawcza: Własne badania ankietowe przeprowadzone metodą CAWI z kadrą kierow­niczą parków objętych próbą badawczą z wykorzystaniem narzędzia Agile Suitability Filter Tools określonego w PMBoK® Guide 2017 badającego potencjał organizacji w trzech aspektach: kultura (struktura) – zespół (ludzie) – projekty. Zastosowano także analizę materiałów źródłowych, w tym porównawczą przepisów prawnych odnoszących się do parków i źródeł finansowania projektów.

Wyniki: W parkach przeważa zwinne (agile) podejście do zarządzania projektami. Jednakże ze względu na specyfikę parków jako organizacji typu not-for-profit oraz na realizowane przez nie projekty, źródła i zasady ich finansowania postuluje się dostosowanie metodyki zarządzania projektami do odpowiednich rodzajów projektów, wewnętrznych możliwości organizacji oraz warunków określonych przez jej otoczenie zewnętrzne, w tym instytucje UE, krajowe lub regionalne dofinansowujące projekty ze środków publicznych.

Artykuł zawiera ocenę i kwalifikację bezpieczeństwa energetycznego, które nie są możliwe bez analizy uwarunkowań systemu energetycznego, zdeterminowanego modyfikacją kierunków polityki energetycznej. Zagadnienie to zostało również przedstawione przez pryzmat założeń strategii Europejskiego Zielonego Ładu Unii Europejskiej, która ma przyczynić się, poprzez promowanie odnawialnych źródeł energii, do poprawy bezpieczeństwa energetycznego.

Cel badawczy: Badania mają na celu ocenę polskich i unijnych regulacji prawnych w zakresie bezpieczeństwa energetycznego. Są próbą odpowiedzi na pytanie, czy odnawialne źródła energii stanowią przesłankę poprawy bezpieczeństwa energetycznego.

Metoda badawcza: W opracowaniu wykorzystano metodę formalno-dogmatyczną, jak również metodę prawnoporównawczą.

Wyniki: Pozytywnie należy ocenić rozwiązania prawne dotyczące odnawialnych źródeł energii, które są wprost traktowane jako przesłanka bezpieczeństwa energetycznego i istotny element polityki energetycznej. Obok przypisywanej odnawialnym źródłom energii cechy niskiego negatywnego wpływu na środowisko coraz wyraźniej wskazuje się w ich kontekście na problem bezpieczeństwa energetycznego wewnętrznego i zewnętrznego państwa.

Influence of Different Decontamination Approaches on Bone Substitute Adhesion to Peri-Implantitis Affected Implant Surfaces: An SEM Proof of Principle Study
Authors: Gamal Ahmed Y.
Published: January 2021

Background: During healing, clot blended graft materials may retract away from implant surfaces creating microgaps that compromise re-osseointegration. The present study aimed to evaluate different surface decontamination materials’ effect on adhesion of the graft materials to peri-implantitis affected parts, a factor that can resist clot blended graft retraction improving re-osseointegration. Methods: Eighteen peri-implantitis affected implants diagnosed as hopeless and designated for removal contributed in this prospective, masked trial. Samples were randomly distributed into three groups, each of six implants. Group one (G1) was coated with hydroxyapatite of a micro particle size of 250 to 1000 µm after saline surface decontamination for two minutes. Group two (G2) peri-implantitis affected parts were treated with the graft material following two minutes of chlorhexidine gluconate 0.12% (CHX) surface treatment. Group three (G3) implants were coated with the graft material after citric acid (CA) (pH = 1) surface conditioning for two minutes. Implants in all groups were agitated in phosphate-buffered saline (PBS) by using an automatic tissue processor agitator for three minutes. Implants were prepared for surface scanning evaluation. Results: Scanning electron microscopy (SEM) observation of G1 saline treated control implants were devoid of bone particles adherent to peri-implantitis affected surfaces. The surface area covered by grafted particles in G2 was statistically higher than that of G1 (P<0.01). Group three (CA-treated) showed nearly complete coverage of peri-implantitis affected parts by the graft material covering 88.8% of examined surface areas which was statistically higher than that of G2 (P<0.05). Conclusion: Citric acid implant surface conditioning could improve implant re-osseointegration through enhancement of the graft adhesion to the implant surface. Smear layer barrier effect seemed to be the most important factor that compromised graft adhesion to preri-implantitis affected parts of the implant surfaces.

Main eigenvalues of a graph and its Hamiltonicity
Authors: Benediktovich V. I.
Published: January 2021

The concept of (κ,τ)-regular vertex set appeared in 2004. It was proved that the existence of many classical combinatorial structures in a graph like perfect matchings, Hamiltonian cycles, effective dominating sets, etc., can be characterized by (κ,τ)-regular sets the definition whereof is equivalent to the determination of these classical combinatorial structures. On the other hand, the determination of (κ,τ)-regular sets is closely related to the properties of the main spectrum of a graph. This paper generalizes the well-known properties of (κ,κ)-regular sets of a graph to arbitrary (κ,τ)-regular sets of graphs with an emphasis on their connection with classical combinatorial structures. We also present a recognition algorithm for the Hamiltonicity of the graph that becomes polynomial in some classes of graphs, for example, in the class of graphs with a fixed cyclomatic number.
Pauli approximation for a vector particle with anomalous magnetic moment in an external Coulomb field
Authors: Voynova Ya. A. , Krylova N. G. , Оvsiyuk E. M.
Published: January 2021

Herein, a spin 1 particle with anomalous magnetic moment in an external Coulomb field is studied. We start with the relativistic tensor system of the Proca type in Cartesian coordinates. In these equations the Γ parameter is present related to an additional characteristic of the particle. In the case of an external magnetic field, it is interpreted as an anomalous magnetic moment. In the presence of an external electric field, additional interaction terms are presented as well; moreover, the terms of the first and second orders in parameter Γ appear. The case of an external Coulomb field is considered in detail. In the nonrelativistic approximation a Pauli type equation is obtained. In the nonrelativistic equation the separation of the variables with the use of spherical vectors is realized. One separate 2-nd order differential equation is found, in which additional interaction terms are missing. Besides, we derive systems of two coupled 2-nd order equations wherein linear and quadratic in parameter Γ interaction terms are presented. Previously, another approach was developed for analyzing the vector particle with anomalous magnetic moment. It was based on the use of tetrad formalism and separation of the variables in the Duffin – Kemmer equation with the help of the Wigner function. The nonrelativistic approximation was performed directly in the system of radial equations. Besides, previously formal Frobenius type solutions for an arising 4-th order differential equation were constructed; however, physically interpretable energy spectra were not found. We have proved that the radial equations derived by different methods are the same up to a simple liner transformation over two radial functions. In this paper, we have obtained a simpler 4-th order equation, the construction of Frobenius solutions becomes technically easier, but physical energy spectra are not found either.
Method for approximate analysis of interaction of material with rolls in a vibroroll grinder

Published: January 2021

The article presents the results of a study of the process of material grinding in roller aggregates with various kinematic features. As the object of research, the design of a vibroroller unit is selected, which has great prospects for use in production. A characteristic feature of this unit is a significant influence on the grinding process of inertia forces. As the main method of research in relation to the movement of the working bodies of the roller and vibroroller shredder and the crushed material, a method of modeling is adopted. It is presented an approximate analysis of the interaction of the crushed material in roll units with rolls. The crushed material is modeled by a set of horizontal elementary layers. At the first stage, the material is crushed in rolls with constant kinematic parameters. Analytical dependencies of the roll pressure on the material are established. At the second stage, the grinding of materials in a vibroroller shredder is considered. A distinctive feature of the vibroroller shredder is the presence of an eccentrically installed roll. The variant is presented when the eccentric performs a curvilinear translational motion, and the roll performs harmonic fluctuation (vibrations) along the coordinate axes with an amplitude of e. The resulting inertia forces and oscillatory motions of the roll are considered. The analysis of the total force in the unit under consideration, which makes it possible to implement crushing-shear and vibration effects on the crushed material, is carried out. The force interaction of the roll with the material is described by two systems of forces: the elastic forces resulting from the contraction of the model layers according to Hooke’s law, and the forces caused by the vibration of the roll (inertia forces). The results obtained are of practical importance in the design of roller units and vibration equipment, as well as for the analysis of the operation of such designs of grinders.

Published: January 2021

Kombinasi baseline data pengindraan jauh sistem aktif dan pasif memiliki banyak keuntungan dalam pemantauan dinamika genangan pesisir. Kedua jenis sensor satelit mengatasi kesenjangan informasi genangan, terutama pada area yang ditutupi awan/bayangan. Tujuan utama penelitian ini adalah untuk mengkaji dinamika genangan di wilayah pesisir Jakarta berdasarkan data multi-temporal sensor optik dari Landsat 8 dan Synthetic Aperture Radar (SAR) Sentinel 1A. Metode penelitian ini menggunakan dua algoritma indeks air. Algoritma tersebut yaitu Modified Normalized Difference Water Index (MNDWI) dan Dynamic Surface Water Extent (DSWE) berdasarkan nilai spektral reflektansi dan formula empirik. Metode lainnya adalah menggunakan nilai rata-rata koefisien backscatter air dari analisis polarisasi tunggal Vertikal Vertikal (VV) dan Vertikal Horisontal (VH). Hasil studi menunjukkan bahwa penggunaan kedua tipe data satelit dengan baseline data 8, 9, 15 dan 16 hari cukup efektif memantau dinamika genangan selama 8-49 hari, termasuk area yang tertutup awan dan bayangan. Berdasarkan nilai threshold dari MNDWI >0,123 dan koefisien backscattering air -19dB cukup efisien digunakan untuk mengesktrak informasi data satelit. Algoritma empiris tersebut menghasilkan kenampakan genangan, terutama di sepanjang tanggul pantai, waduk, ekosistem mangrove dan lahan terbangun. Hasil pemantauan satelit menunjukkan bahwa puncak genangan terjadi pada 30 Mei 2016 dan masih terlihat pada 15 Juni 2016. Kombinasi metode pengindraan jauh tersebut cukup efektif dan efisien untuk memantau genangan secara dinamis.

Authors: Araujo Juliana Lopes de Aguiar , Sousa Ubiratan Wagner de , Aquino Fernanda Mabel Batista de , Lira Luisa Gurgel de , Almeida Iris Maria Rodrigues de Andrade
Published: January 2021

Introduction: Breast synovial sarcoma is extremely rare, with few cases described. It corresponds to 6–9% of soft tissue sarcomas and is more frequent in extremities (80%), trunk (8%), and abdomen (7%) in young adults. It usually does not affect the breast. Objectives: To report a rare case of monophasic breast synovial sarcoma and provide data for the global literature. Method/Case report: G.S.B., 97 years old, presented a 7 cm nodule in the left breast and negative axillary nodes. Ultrasound (US) revealed a heterogeneous nodule of 6.0 x 5.5 cm, BI-RADS 5. She did not have mammography. Core biopsy showed spindle cell neoplasm. Immunohistochemistry (IHC) indicated mesenchymal lesion, without differentiating stromal components of fibroepithelial tumor from the mesenchymal lesion. Rapid growth with ulceration and tumor bleeding were identified. Urgent mastectomy showed a malignant neoplasm of spindle cell pattern and high grade, with 12 cm, involved lateral margin, and 19 negative axillary lymph nodes. IHC of the surgical specimen indicated monophasic synovial sarcoma. Before the wide excision, she had a rapidly progressive recurrence in the sternum, making it non-resectable. During radiotherapy (RT), local progression was identified. She has been receiving chemotherapy (CT) with ifosfamide and adriamycin. No evidence of distant disease was found after 9 months of diagnosis. Results/Discussion: Synovial sarcoma corresponds to approximately 0.06% of all breast neoplasms, originating from their mesenchymal tissue, with variable epithelial differentiation. The term synovial sarcoma is inadequate, deriving from its frequent juxta-articular location. Its incidence is approximately 1.5 per 1 million individuals, with a mean age of 32 years and a male:female ratio of 1.2:1. The main histological subtypes are: classic biphasic and monophasic. Translocation t(X;18) (p11.2; q11.2) and expression of SYT/SSX gene fusion are present in more than 95% of cases. IHC shows an intense expression of vimentin and CD99, and focal of Bcl2, EMA, CKAE1-AE3, actin, and desmin, as well as negativity for S100, cytokeratins, hormone receptors, myosin, and caldesmon. The differential diagnosis is made with other spindle cell entities, such as fibromatosis, solitary fibrous tumor, myofibroblastoma, metaplastic carcinoma, and other sarcomas. Synovial sarcoma has a moderate response to chemotherapy with anthracyclines. The treatment includes wide surgical resection and RT. Metastases occur in about 50% of cases and are present at diagnosis in 16% to 25%; they are more frequent in the lung (75%), regional lymph nodes (15%), and bones (10%), tending to late recurrence and metastases. The 5-year disease-free survival is 60%. Conclusion: The heterogeneity of the disease and its low incidence hinder prospective studies addressing therapeutic options with better long-term results.

Published: January 2021

Introduction: Primary squamous cell carcinoma of the breast (SCCB) is a rare malignant neoplasm, confirmed when at least 90% of the cells are of the squamous type. It represents about 1% of all cases of breast carcinomas. The literature has few reports on the subject, showing that SCCB has no specific radiological features. Objective: To report a case of SCCB diagnosed at the Instituto do Câncer Doutor Arnaldo Vieira de Carvalho. Method: We conducted a review of medical records, photographic records, and a literature review. Result: An 82-year-old woman had a small breast lesion in 2016, but for fear, she hid it until the end of 2018. In the beginning, the lesion was treated with topical corticosteroids and monitored at a community health clinic. After worsening, she was referred to a specialized service. Upon physical examination, the lesion was firm, exophytic, friable, and non-nodular, with fibroelastic axillary lymph nodes of up to 1.5 cm. The mammography from October 2018 was classified as BI-RADS® 2 and the breast ultrasound as BI-RADS® 3, showing only skin lesion. Incisional biopsy revealed SCCB with immunohistochemistry positive for cytokeratin-14 and protein p63 and negative for hormone receptors (HR) and HER2 expression. She underwent central quadrantectomy with axillary lymph node dissection in April 2019, confirming SCCB and without lymph node involvement (0/14). After 5 months, the patient showed lesions suggestive of herpes zoster, confirmed by serology. Without improvement with acyclovir, a new biopsy was performed, which confirmed local recurrence. In December, she started radiotherapy, but the lesion progressed to necrosis, papules, and extended to the dorsum, accompanied by intense pain. Chemotherapy with cisplatin 30 mg/m² weekly was proposed, with partial response. Conclusion: SCCB at diagnosis has >4 cm, and 50% of them have associated cysts. Usually, it has a high grade and is negative for HR and HER2 expression. Mammographic images do not have specific features, explaining the large lesions during screening. The literature review revealed that 70% of SCCB patients do not have lymph node involvement, but due to its unpredictable spread, lymph node dissection might be conducted for staging. It is considered an aggressive disease with an uncertain prognosis, and the data available is not enough to provide options to prevent recurrence. SCCB is rare, has a poor prognosis, and surgery is the most accepted initial treatment. In the case of recurrence, the treatment of choice is radiotherapy associated with cisplatin-based chemotherapy and anti-PD-L1 immunotherapy (cemiplimab), which was recently approved by the Food and Drug Administration (FDA).

Published: January 2021

Verifica-se a partir da existência de instrumentos voltados especificamente para a regularização do atendimento educacional às crianças autistas, que entender como essas crianças estão sendo recebidas na educação infantil é um aspecto chave para a garantia de qualidade da educação. Assim, o artigo tem o objetivo de socializar reflexões de estudos sobre o transtorno do espectro autista na etapa da educação infantil no Brasil.  Para tanto, utilizou-se como metodologia o levantamento bibliográfico no banco de dados Scientific Electronic Library Online (SciElo). Nesse sentido, teve-se como problema norteador de pesquisa a seguinte questão: Quais as preocupações que a literatura especializada na área traz nas pesquisas sobre o autismo na educação infantil? Diante das análises realizadas nos trabalhos que tratam do autismo na educação infantil conclui-se que as preocupações que a literatura especializada na área traz nas pesquisas baseiam-se na prática pedagógica dos professores e também há uma preocupação com o brincar das crianças com TEA.
Friction and temperature mapping of environmentally acceptable gear oils
Authors: Bayat Reza , Lehtovaara Arto
Published: January 2021

In recent years, environmental issues have raised the demand to protect the environment against the pollution caused by the uncontrolled spillage of lubricating oils. One solution is using Environmentally Acceptable Lubricants (EALs), however, these oils are more expensive than the common mineral oils. The consumers require to test the oil performance using test machines but testing in real machines is costly and time-consuming. Small test machines like ball-on-disc have been previously used for friction mapping and ranking gear oils. In this paper, the friction maps are measured from 0.65 GPa to 1.25 GPa, and temperature maps are devised to experimentally simulate the gear contact along the line of action. Results illustrate that EALs can provide up to 60 % better frictional efficiency that leads to 20 oC cooler oil temperature in high-pressure contacts operating under elastohydrodynamic lubrication (EHL) regime.
A One Health Perspective for Defining and Deciphering Escherichia coli Pathogenic Potential in Multiple Hosts
Authors: García Alexis , Fox James G
Published: January 2021

E. coli is one of the most common species of bacteria colonizing humans and animals. The singularity of E. coli 's genus and species underestimates its multifaceted nature, which is represented by different strains, each with different combinations of distinct virulence
factors. In fact, several E. coli pathotypes, or hybrid strains, may be associated with both subclinical infection and a range of clinical conditions, including enteric, urinary, and systemic infections. E. coli may also express DNA-damaging toxins that could impact cancer development.
This review summarizes the different E. coli pathotypes in the context of their history, hosts, clinical signs, epidemiology, and control. The pathotypic characterization of E. coli in the context of disease in different animals, including humans, provides comparative and One
Health perspectives that will guide future clinical and research investigations of E. coli infections.

Предложенный ранее новый экспериментальный способ оценки детонационной способности (ДС) топливно-воздушных смесей (ТВС), основанный на измерении расстояния и/или времени перехода горения в детонацию (ПГД) в эталонной импульсно-детонационной трубе (ЭДТ), использован для ранжирования газовых ТВС по их ДС в существенно одинаковых термодинамических и газодинамических условиях. В экспериментах использованы ТВС на основе водорода, ацетилена, этилена, пропилена, пропан-бутана, н-пентана и природного газа (ПГ) разных составов: от предельно обедненных до предельно обогащенных горючим при нормальных значениях температуры и давления. Предложена концепция«эквивалентных» ТВС, имеющих одинаковую или близкую ДС при одинаковых условиях. «Эквивалентные» ТВС могут использоваться для предсказательного физического моделирования взрывных процессов с участием ТВС других горючих.

The moods and categories of consumers of fashion industry goods analysis in the context of global processes are the main purposes of this study. Methodology. An analytical method was used to study consumer trends in the fashion industry. The main categories of consumers of the fashion industry are determined by the method of synthesis. It is recommended to integrate the obtained categories by the induction method into the marketing activity of the fashion brands. Results. The most important moods of world consumers in the conditions of global world processes were investigated in the work. Four main sentiments have been identifi ed: fear, just resilience, a desynchronized society, and radical optimism. In order to establish the main ways of behavior of players in the market of the fashion industry, the categories of consumers of industrial goods were identifie d: stabilizers, settlers, new optimists. The key areas of new methods of interaction of fashion brands with consumers are the following: - ease of decision-making (sales in stores with a limited range will grow);- quiet trade (rejection of daily uncertainties);- unifi ed commerce (creates uninterrupted interaction with customers on all channels);- referral to archives (resale industry shows signs of acceleration);- hyperlocalized social commerce (possibility of earning a commission for all participants of the offline / online retail chain);- attracting attention to the cities of the second level (shifting attention from oversaturated cities of the 1st level to remote cities of the 2nd level, providing high-speed logistics);- AR / VR purchases (use of virtual reality);- evolution on demand (simplifi cation of US-design (user experience) in the online space                                                                                  - capacity (and savings) of packaging (group purchases at reduced prices, minimization of packaging).The obtained data are recommended for implementation in marketing and management activities of Ukrainian fashion brands.

لم تثر قضية من القضايا الاسلامية جدلا" واسعا" في الزمن المعاصر مثلما اثارت قضية تطبيق الشريعة الاسلامية ، فبقدر مااستعملت القوى الاسلامية هذا الهدف ، أو وظفته خلال مسيرتها للوصول الى السلطة من خلال التعلق بالمقدس كنمط دافع أو رافع باتجاه السلطة، أو تولي امور الحكم ، بيد أن الواقع يجسد ... هذا الهدف بقي بحدود الشعارات بمعنى شعار غائي ولم يتجاوزه حدود المناداة به أو الترتيب بأنها المصدر الاساس للتشريع مع اختلافات المنطق الغائي،  بالقدر الذي عكس اشكالية فكرية حول صدقية استعمال هذه  القدرة تطبيق الشريعة وانفاذها في عالم اليوم ، فهي  قراءة فكرية للموضوع ورغبة في توضيحه، ومحاولة "لاستكشاف وعرض أهم المشكلات التي قد تحول دون تطبيقه .و لتسليط الضوء على هذه الفكرة فقد تم تقسيم البحث على ثلاثة مباحث . تناول المبحث الأول تطبيق الشريعة كخلفية تاريخية ، بينما تناول المبحث الثاني المعوقات التي تؤمن تحقيق المنع من تحقيقها ، بينما سلط المبحث الثالث الضوء على الاشكالات التي قد تنتج عن محاولات تطبيقها .
السياسة العامة التعلمية في العراق الواقع والحلول المقترحة

Published: January 2021

تحضى موضوعة السياسة العامة في كل دول العالم اهتماماً حكومياً وبحثياً لما لها من قدرة على كشف الكثير من المشكلات التي تواجه الدولة وقدراتها التنظيمية والعلمية ووضع الحلول والمعالجات المناسبة التي تتجاوز العشوائية والارتجالية وردود الفعل، ونتيجة لهذا الاهتمام فقد عملت الكثير من الدراسات محاولةً تأطيرها مفاهيمياً واكاديمياً. فقد ارتبط مفهوم السياسة العامة بجوانب متعددة من السياسات العامة كالسياسة الاجتماعية أو الاقتصادية أو التعليمية أو الزراعية أو غيرها، فالسياسة العامة مهما اختلف مدلولها وارتباطها فهي تشير للتفكير المنظم الموجه لسلوك وتصرفات برامج الدولة أو المنظمة أو الافراد بأتجاه تحقيق اهداف المجتمع وتحسين نمط حياته.
   ومن ثمّ وبقدر تعلق الامر بموضوعنا، فلا بد من وجود سياسة عامة تعليمية وتربوية قادرة على تعبئة الموارد المتاحة سواء أكانت بشرية أم ماديةأم علمية في اطار فلسفة الدولة متجهة لتطوير المجتمع من خلال قيادة عمليات التنمية وحل المشكلات التي تواجه هذا الجانب المهم والحيوي الذي اصابه الكثير من الوهن على مستواه المحلي مقارنة بالعربي والعالمي، نتيجة عدة عوامل واسباب سنتناولها في اطار دراستنا هذه.
الحقوق الدولية لتعزيز المشاركة الفاعلة لدى الشباب العراقي

Published: January 2021

بعد التحول الديمقراطي عام 2003 في العراق انتظر الشباب كثيراً ان يأخذوا فرصتهم الحقيقية في المشاركة السياسية، إلا ان أغلب القوانين المنظمة للعمل السياسي والانتخابي قد جاءت مجحفة بحق الشباب، فبالرغم من التطورات بالقوانين والتشريعات الا ان الفرص لم تكن تتيح للشباب من المشاركة السياسية، مما انعكس بصورة سلبية على مشاركتهم في التصويت والترشيح بل حتى تقلدهم المناصب والوظائف العامة، وهذا مما سبب تذمرهم على الطبقة الحاكم والنظام السياسي عن طريق الاحتجاجات، أو عند طرق رفضهم بالانتخاب وهذا مما نعكس على الانتخابات البرلمانية الاخيرة وانخفاض نسب المشاركة.

Published: January 2021

Neste artigo, examinamos o processo de construção simbólica do Dia das Crianças no Brasil, a fim de compreender os significados edificados em torno dessa data comemorativa e a mobilização de diferentes agentes para sua consolidação. Para tanto, investigamos reportagens e anúncios publicados na imprensa brasileira no período entre 1910 e 1960 e decretos governamentais. A análise de estratégias publicitárias demonstra a atuação do comércio e de produtores de bens relacionada à fixação periódica da celebração. Verificamos como a criação do Dia das Crianças e sua ritualização pelo consumo dramatizam o imaginário de uma nação que se engendrou sob o epíteto ufanista “país do futuro”.
