يخطا من يظن ان الديمقراطية صندوق انتخابي فحسب بل هي منظومة متكاملة من المستلزمات التي يفترض ان تكون متواجدة لغرض تحقيق الهدف و الغاية من وجودها ، ذهاب المواطن للمشاركة في الانتخابات هي الخطوة الاولى و ليست الاخيرة في دوره في العملية الديمقراطية ، فلا يمكن ان ينتهي دور الناخب بمجرد اختيار من يمثله في البرلمان ، بل هناك ضرورة ليشارك المواطن في جميع مفاصل العملية السياسية حتى بعد انتهاء العملية الانتخابية ، و بقاء الديمقراطية شكلاً دون مضمون تفرغها من محتوها .
الديمقراطية في العراق تجربة بحاجة الى مزيداً من المعالجات منها ذات طابع فكري و اخرى ذات طابع اصلاحي مؤسساتي و دستوري ، و من اهم التحديات التي تواجها هو التحول من مراحلها الاولية ( التوافقية ) الى المراحل الدائمة ( الرسوخ الديمقراطي ) ، و هذا التحول ليس يسيراً في ظل الصراعات و الاختلافات بين الكتل السياسية ، فضلا عن غياب الرغبة الشعبية في دعم هكذا دعوات اصلاحية كون الذهنية المكوناتية هي التي تهيمن على المشهد السياسي الحالي مع غياب شبه تام الى الهوية الوطنية القائمة على اساس المواطنة العراقية .

Authors: Américo Francisco , Bacar João Gervásio 
Published: July 2023

Impactos socioambientais são o resultado das actividades antrópicas levadas a cabo numa determinada área geográfica, que resultam na modificação da topografia, da vegetação e de toda a biodiversidade. Alguns problemas dos impactos socioambientais são provocados por aspectos ambientais que trazem consequências ao ambiente. Outras causas que se levantam nessa problemática têm a ver com as mudanças climáticas devido aos factores naturais, bem como a interferência humana no exercício das suas actividades, a partir da prática da agricultura, corte desenfreado de árvores para diversos fins, além da extracção da areia nos principais rios e riachos da cidade de Lichinga. O presente trabalho pretende avaliar os impactos ambientais causados pela actividade de extracção de areia no rio Nzinje, na cidade de Lichinga, Província do Niassa. Faz referência aos principais impactos socioambientais e traz à tona as motivações dos sujeitos na prática dessa actividade extractiva. Foram realizados estudos literários para depois seguir-se no campo através de observação e entrevistas acidentais. Foi possível registrar algumas práticas nocivas desta actividade com objectivo de propor medidas tendentes a mitigar os possíveis impactos que podem produzir para a sociedade e demonstrar a importância de se manter o ambiente saudável e sustentável. Portanto, esta prática pode contribuir para a alteração do curso normal das águas do rio e da paisagem natural, para além do risco de desaparecerem as espécies animais e a vegetação ribeirinha, ou seja, da biodiversidade no geral.

Published: July 2023

Senegalese Associationism in Italy: Social Practices and Territorialisation Dynamics. The article focuses on Senegalese associations in Italy, trying to identify the territorial factors that influenced its evolution, in particular the development of new projects and stronger, multi-located and institutionally recognized relational networks. The survey conducted in different Italian contexts brought out a diversified geography of Senegalese associations which offers some consideration about the possibility of considering these associations as real agents of territorial development, both in territories of origin than in those of destination, as well as evaluating the role that local policies, in the field of inter-culture, can play in encouraging the active participation of these organizations in local public life and in strengthening the territorial social capital.
A Comparison between EFL Writing Errors in Computer-Based and Paper-Based Assignments
Authors: Caleffi Paola Maria 
Published: July 2023

Advances in writing technologies have fostered the gradual move from Paper-Based (PB) to Computer-Based (CB) writing assessment in foreign language (FL) education. The trend was further boosted by the outburst of the Covid-19 pandemic, which led to drastic changes in teaching and assessment practices. In higher education (HE) contexts, writing assessment in English as a foreign language (EFL) is more and more often managed by means of online learning platforms, where students create and submit written assignments on the computer. This paper examines a sample of 100 EFL exam essays completed by 100 Italian university students. Half of the essays were computer-typed on Moodle from home during the Covid-19 lockdown, whereas the other half were handwritten on paper during a face-to-face exam session after the Covid-19 emergency. The study presented herein compares the amount and types of formal errors in the CB and PB written assignments respectively. The results of the comparison may be useful to suggest hypotheses on the impact that both writing modality and environment can have on the quality of EFL writing in assessment contexts.

Authors: Pettinelli Alessandra , Rauch Dalila 
Published: July 2023

The Role of the ‘Feedback’ Function in Moodle Activities. The development of online language teaching has accelerated over the last few years, and there is now an increasingly urgent need to deepen our knowledge of the functions of the available platforms. The aim of this presentation is to highlight the potential of the ‘Feedback’ function provided by the Moodle platform. The contribution deals with the Italian language courses offered by the Language Centre of the University of Perugia, with a view to showcasing some specific cases of the use of this tool, which enables the teacher to take on the role of facilitator of the learning process and the student to acquire greater autonomy in learning and self-assessment, without reducing the teacher-learner interaction. In fact, thanks to this function, teachers can add formative and reflective comments for each possible answer given by the student, for the purpose of fostering motivation, stimulating metalinguistic awareness and elucidating certain morphosyntactic structures or communicative functions.

Published: July 2023

Aims: The paper aimed to clarify the effect of Jingdusha on chlorophyll fluorescence parameters of cucumber seedlings under Corynespora cassiicola stress.
Study Design: We applied the method of artificial inoculation in the pot and analyzed the changes in the content of chlorophyll and chlorophyll fluorescence parameters.
Place and Duration of Study: In 2018, these experiments were conducted in the College of Bioscience and Biotechnology of Shenyang Agricultural University (Lab 240).
Methodology: The seedlings in the two-leaf period were induced by 2.0 mL·L-1 of Jingdusha, then inoculated C. cassiicola for 24 h. Cucumber seedlings of each treatment group were randomly selected for the content of chlorophyll and chlorophyll fluorescence parameters determination. The leaves of cucumber seedlings in each treatment group were randomly collected at 1 d, 3 d, 5 d, 7 d and 9 d after inoculation for the determination of the content of chlorophyll and chlorophyll fluorescence parameters.
Results: When C. cassiicola infects cucumber, Jingdusha can effectively increase the energy conversion efficiency of the PSII central response and the potential activity of PSII, besides, the photosynthetic reaction activity did not change significantly in the early stage, but increased significantly in the later stage and rescure the degree of photosynthetic structural damage.
Conclusion: In conclusion, under C. cassiicola stress, plant immune resistant inducer Jingdusha can effectively increase the capacity of PSII and the efficiency of PSII operation under the light in cucumber seedlings, reduce the damage of photosynthetic structure, increase the ability of PSII to accept and transfer electrons, as well as reduce the degradation of chlorophyll and the dissipation of light energy under C. cassiicola stress.

ImportanceHead and neck squamous cell carcinoma is a highly lethal cancer that is often associated with human papillomavirus (HPV). Recent studies have shown promise in the use of HPV DNA detection in salivary rinses and plasma as a factor associated with a future diagnosis of HPV-positive oropharynx cancer (HPVOPC). However, the use of plasma and salivary HPV DNA detection in defining risk for recurrence in the context of a prospective, phase 3, clinical trial coupled with standardized clinical surveillance has not been reported.ObjectiveTo identify patients with low-risk HPVOPC at risk for recurrence by detection of HPV16 DNA in plasma and salivary rinses.Design, Setting, and ParticipantsIn this cohort study, 233 low-risk patients were recruited from 32 head and neck treatment centers in Ireland (1 [3.1%]), the Netherlands (1 [3.1%]), and the UK (30 [93.8%]) as part of the DE-ESCALATE HPV trial, an open-label, phase 3 randomized clinical trial examining treatment with cetuximab vs cisplatin for HPVOPC. Patients were assayed for the presence of HPV16 DNA in plasma and salivary rinse via a quantitative polymerase chain reaction–based assay.Main Outcomes and MeasuresAssay results were associated with risk of recurrence and lead time from HPV16 DNA detection to recurrence.ResultsOf 233 patients, 45 (19.3%) were women, and the mean (SD) age was 57.01 (8.45) years. A total 1040 salivary or blood samples were collected during the course of the study. With a median follow-up of 760 days, the sensitivity and specificity of combined plasma and salivary rinse HPV DNA assays for detecting recurrence were 65% and 87%, respectively. There was a median lead time of positive test to event/recurrence date of 19 days (range, 0-536 days) and mean (SD) of 122 (169.8) days.Conclusion and RelevanceThe results of this cohort study suggest that in the setting of a randomized, prospective, phase 3 trial for low-risk patients with HPVOPC, posttreatment presence of HPV DNA in plasma and salivary rinses is associated with recurrence; a lead time between test positivity and clinical recurrence offers a potential opportunity for earlier detection of recurrence.
