Once the tomato gets infected with C. coccodes, the anthracnose develops within a few days. Therefore, early detection of the fungal infection is vital for successful prevention and effective treatment of the infected fields. This study aimed to employ the electronic nose (EN), with metal-oxide sensors (MOS), to sense the presence of C. coccodes on tomato fruits at different stages and concentrations. Identification of C. coccodes was carried out using the polymerase chain reaction (PCR), where the identification of C. coccode fungus was achieved using three different primer sets: ITS1F/ITS4, Cc1F1/Cc2R1, and Cc1NF1/Cc2NR1. In which ITS1F/ITS4 was a general primer set for most Ascomycetes and Basidiomycetes. Cc1F1/Cc2R1 primer set was a specific primer to Colletotrichum spp., which gives a 447 bp product, and Cc1NF1/Cc2NR1 was a unique primer to C. coccodes, which results in a 349 bp product. In addition, three homogeneous tomato samples were injected with three different concentrations: 30*103 , 30*104 and 30*105 conidial fungal suspension, three other tomatoes were used as negative controls, and all were measured using an EN device every two days for ten days. Specific primers (ITS1F/ITS4, Cc1F1/Cc2R1, and Cc1NF1/Cc2NR1) could recognize and specify C. coccode fungus using a suitable PCR program and sequencing. xiv The data acquired from the EN sensors were analyzed using principal component analysis (PCA). It was found that the EN device could sense pathogen occurrence at early stages, i.e. after two days of the infection, and before the appearance of any symptoms, where the PCA scores plot explained 100% of the total variance. In addition, the overall scores plot explained 100% of the total variance indicating the ability of EN to differentiate between different stages of infection duration ( i.e. second, fourth, sixth, eighth, and tenth day). Moreover, the concentration of the infected samples was clearly differentiated on the sixth, eighth and tenth days. 2022-06-05T00:00:00Z https://scholar.ptuk.edu.ps/handle/123456789/968 Title: The Mediating Role of Innovative Climate in the Relationship Between the Transformational and Transactional Leadership Styles and Administrative Innovation in Palestinian Ministry of Education from the point of view of female employees. Authors: AL-shalabi, Aisha Abstract: This study aims at identifying the relationship of leadership patterns (transformational and transactional) and their impact on management innovation through the mediating role of the innovative climate at the headquarters of the Palestinian Ministry of Education. The researcher followed the analytical descriptive approach where the questionnaire was selected as a study tool for achieving the purposes of the study, with the aim of collecting the primary data from the study community that was represented in all of the (263) female staff working at the headquarters of the Palestinian Ministry of Education, using the comprehensive survey method. (124) questionnaires had been handled back, and they were all good for analysis. In addition, interviews were conducted with (6) officials of the ministry in study with a view to obtaining explanations of unexpected results in the quantitative phase, describing differences in the effects of both transformational and transactional leadership. The hypotheses were analyzed and tested using (PLSsmart - 3) through the use of Structural Equation Modeling (SEM). And after the analysis and hypothesis of the study data, the study produced a series of findings, most notably, The level of practice by officials in the Palestinian Ministry of Education of the two patterns of transformational and transactional leadership was medium, while the pattern in both of leadership ranked first in terms of practice and from the point of view of female employees, in addition to the fact that the level of availability of both administrative innovation and the innovative climate within the Palestinian Ministry of Education was also medium. , while the level of availability of administrative innovation was at a higher level than the innovative climate, and the current study confirmed the existence of a positive, statistically significant effect of the two styles of transformational ف leadership and transactional leadership on administrative innovation through the mediating role of the innovative climate. Although it was proven that all the hypotheses are statistically significant, the results indicated that there is a positive, non-statistically significant effect of transactional leadership on administrative innovation. The study also came up with a number of recommendations based on the results of the study, the most important of which is the need to strengthen the practices of the transformational and transactional leadership styles among officials in the Palestinian Ministry of Education until they reach a high level of application, the most important of which are those practices that encourage or reward innovation and present new ideas, in addition to The need to work on spreading the culture of innovation within the Palestinian Ministry of Education and at all administrative levels, to enhance the climate that encourages innovation to reach a high degree of availability, as well as the need for officials in the Palestinian Ministry of Education to focus on finding a common understanding of the objectives of the public ministry by employees and at all administrative levels This can be done through holding periodic meetings or to discuss those goals and the priorities for achieving them. 2022-02-05T00:00:00Z https://scholar.ptuk.edu.ps/handle/123456789/967 Title: Human Resources Information Systems and their Impact on the Performance in the Public Sector: the Mediating Roles of Information Sharing and Employee Commitment Authors: Jarrar, Amani 2022-02-02T00:00:00Z https://scholar.ptuk.edu.ps/handle/123456789/966 Title: The Impact of Strategic Planning Practices on the Sustainable Development of Industrial Cities Through Competitive Advantage Authors: Daqqa, Mohammad Abstract: هدفت هذه الدر اسة الى استكشاف مستوى تطبيق ممارسات التخطيط االست ارتيجي في الشركات العاملة في المدن الصناعية الفلسطينية. كذلك تم دراسة العالقة ما بين ممارسات التخطيط االستراتيجي والتنمية المستدامة في هذه الشركات، باالضافة إلى الكشف عن الدور الوسيط الذي تلعبه الميزة التنافسية كمتغير وسيط في العالقة ما بين ممارسات التخطيط االستراتيجي والتنمية المستدامة استخدمت الدراسة المنهج الكمي من خالل استخدام المسح كأداة لجمع البيانات ، وتكون مجتمع الد ارسة من جميع اإلداريين والمد ارء ورؤساء األقسام في الشركات العاملة في المدن الصناعية في فلسطين والبالغ عددهم 183 فردا، وبلغت عينة الدراسة 127 فردا من المجتمع األصلي، تم جمع بيانات الدراسة بوساطة استبانة اعدت لهذا الغرض، تم استخدام نموذج المعادالت الهيكلية )SEM )إلختبار فرضيات الدراسة وذلك عن طريق تطبيق برنامج -SMART 7.3 PLS .كشفت النتائج المتعلقة بالد ارسة أن ممارسات التخطيط االست ارتيجي تطبق على مستوى متوسط في الشركات العاملة في المدن الصناعية الفلسطينية، كما أظهرت النتائج وجود أثر ذو داللة إحصائية عند مستوى داللة (05.0 ≤ α )لممارسات التخطيط االستراتيجي على التنمية المستدامة، وأن الميزة التنافسية جزئيا العالقة بين ممارسات التخطيط االستراتيجي والتنمية المستدامة. أوصت الدراسة بعدة توصيات تتوسط كان أهمها تحسين الية وضع الخطط االستراتيجية بما يتالءم مع متطلبات التنمية المستدامة، واستخدام مؤشرات أداء واضحة لمراقبة تنفيذ الخطة اإلستراتيجية والتنفيذية، باالضافة الى ضرورة قيام الشركات العاملة في المدن الصناعية في فلسطين بتطبيق السياسات و المنهجيات االدارية الحديثة لتخفيض تكاليف اإلنتاج. 2022-01-09T00:00:00Z
