The Effect of Positive Psychological Capital Dimensions on Organizational Creativity

هدفت الدراسة الحالية إلى محاولة التعرف على التغييرات الملاحظة التي تحدثها أبعاد رأس المال النفسي الإيجابي من خلال تأثيرها على الإبداع التنظيمي، ولتحقيق أهداف هذه الدراسة إعتمد الباحثان على المنهج الوصفي  التحليلي، وتم إختيار عينة عشوائية مكونة من (79) عاملا بنقاط البيع الخاصة بعلامة ديفاكتو بالجزائر والموزعة في كل من (الجزائر العاصمة، البليدةـ، عين الدفلى، مستغانم، وهران)، وتم الإعتماد على الإستبيان كأداة لجمع البيانات، وبعد التحقق من خصائصه السيكومترية، ثم تطبيقه على عينة الدراسة الأساسية، قمنا بتحليل البيانات بإستخدام الأساليب الإحصائية اللازمة وبالإعتماد على برنامج الرزمة الإحصائية للعلوم الإجتماعية، وتوصلنا إلى أن أبعاد رأس المال النفسي الإيجابي مجتمعة تؤثر في الإبداع التنظيمي، كما أنه من بين الأبعاد الأربعة لرأس المال النفسي الإيجابي من حيث أهميتها في إحداث التأثير في الإبداع التنظيمي جاء بعد المرونة في المرتبة الأولى، ثم بعد الأمل جاء في المرتبة الثانية، بينما المرتبة الثالثة كانت لبعد الكفاءة الذاتية، وبالنسبة لبعد التفاؤل كان في المرتبة الرابعة لكن أظهرت النتائج عدم أهميته إحصائيا حيث أن مستويات الدلالة المحسوبة كانت أكبر من مستوى (05.) مما يدل على عدم وجود درجة أثر دالة إحصائيا لهذا البعد في الإبداع التنظيمي من وجهة نظر العاملين.The current study essays to identify the observed changes that the dimensions of positive psychological capital bring about through its effect on organizational creativity. To achieve the goals of this study, the researchers rely on the descriptive approach, and a random sample consisting of (79) workers is chosen, with points of sale for the brand Defacto in Algeria located in Algiers, Blida, Ain Defla, Mostaganem and Oran. The questionnaire is used as a tool to collect data, and after checking its psychometric properties, it is applied to the basic study sample. We analyze the data using the necessary statistic methods, and by relying on the Statistical Package Program for Social Sciences, we conclude that the dimensions of positive psychological capital combined affect organizational creativity. Indeed, there are four dimensions to positive psychological capital, at the top of the list was flexibility, followed by hope, self-efficacy and lastly optimism. However, the results showed that this latter is not statistically significant, since the calculated significance levels were greater than level (05.), which indicates that there is no statistical significance to the effect of optimism on organizational creativity from the perspective of workers

Diversity in anopheline larval habitats and adult composition during the dry and wet seasons in Ouagadougou (Burkina Faso)

Background: Several cases of malaria are frequently recorded during the dry period in Ouagadougou town (Burkina Faso). This has led to the design of a series of studies focusing on both parasitological and entomological investigations intended to provide relevant health data on the risk of local malaria transmission according to the way of urbanisation. Methods: A cross-sectional entomological survey was carried out in various districts of Ouagadougou in April and October 2006. Adult malaria vectors were collected using CDC traps and indoor insecticide spraying performed in four houses during four consecutive days/nights. Intensive larval sampling was also done in available water ponds throughout the study sites. Results: In April, the anopheline breeding sites consisted only of semi-permanent or permanent swamps located mainly in the two peripheral districts. Despite the presence of anopheline larvae in these breeding sites, less than five Anopheles gambiae s.l. adults were caught by CDC traps and indoor insecticide spraying. In October, additionally to the permanent breeding sites reported in April, some rainfall swamps were also found positive to anophelines. The number of adults' mosquitoes was higher than that collected in April (2 vs 159 in October). Out of 115 larvae of An. gambiae s.l. analysed by PCR in April, 59.1% (68/115) were identified as Anopheles arabiensis, 39.1% (45/115) as An. gambiae M while the S form represented less than 2%. Overall 120 larvae and 86 females were identified by PCR in October as An. gambiae M form (51%) and An. arabiensis (42.2%). The S form represented only 6.8%. The global sporozoite rate recorded was high (6.8%) and did not differ between the districts except in the central district where no positive mosquito was detected. Conclusion: Although only few adults' mosquitoes were actively caught during the driest month, malaria vectors persisted all year long that increases the risk of urban malaria transmission. The distribution of breeding sites and especially the occurrence of malaria vectors were more abundant in the periphery, which is more like that of a rural settlement. The evolution of malaria prevalence and the factors sustaining the risk of transmission in Ouagadougou as well in many African cities during the dry season are discussed

Surveys of Arboviruses Vectors in Four Cities Stretching Along a Railway Transect of Burkina Faso: Risk Transmission and Insecticide Susceptibility Status of Potential Vectors

Background: A severe outbreak of dengue occurred in Burkina Faso in 2016, with the most cases reported in Ouagadougou, that highlights the necessity to implement vector surveillance system. This study aims to estimate the risk of arboviruses transmission and the insecticide susceptibility status of potential vectors in four sites in Burkina Faso.Methods: From June to September 2016, house-to-house cross sectional entomological surveys were performed in four cities stretching along a southwest-to-northeast railway transect. The household surveys analyzed the presence of Aedes spp. larvae in containers holding water and the World Health Organization (WHO) larval abundance indices were estimated. WHO tube assays was used to evaluate the insecticide susceptibility within Aedes populations from these localities.Results: A total of 31,378 mosquitoes' larvae were collected from 1,330 containers holding water. Aedes spp. was the most abundant (95.19%) followed by Culex spp. (4.75%). Aedes aegypti a key vector of arboviruses (ARBOV) in West Africa was the major Aedes species found (98.60%). The relative larval indices, house index, container and Breteau indexes were high, up to 70, 35, and 10, respectively. Aedes aegypti tended to breed mainly in discarded tires and terracotta jars. Except in Banfora the western city, Ae. aegypti populations were resistant to deltamethrin 0.05% in the other localities with low mortality rate under 20% in Ouagadougou whereas they were fully susceptible to malathion 5% whatever the site. Intermediate resistance was observed in the four sites with mortality rates varying between 78 and 94% with bendiocarb 0.1%.Conclusions: This study provided basic information on entomological indices that can help to monitor the risks of ARBOV epidemics in the main cities along the railway in Burkina Faso. In these cities, all larval indices exceeded the risk level of ARBOV outbreak. Aedes aegypti the main species collected was resistant to deltamethrin 0.05% and bendiocarb 0.1% whereas they were fully susceptible to malathion 5%. The monitoring of insecticide resistance is also important to be integrated to the vector surveillance system in Burkina Faso

Pilot study on the combination of an organophosphate-based insecticide paint and pyrethroid-treated long lasting nets against pyrethroid resistant malaria vectors in Burkina Faso

International audienceA pilot study to test the efficacy of combining an organophosphate-based insecticide paint and pyrethroid-treated Long Lasting Insecticide Treated Nets (LLINs) against pyrethroid-resistant malaria vector mosquitoes was performed in a real village setting in Burkina Faso. Paint Inesfly 5A IGR™, comprised of two organophosphates (OPs) and an Insect Growth Regulator (IGR), was tested in combination with pyrethroid-treated LLINs. Efficacy was assessed in terms of mortality for 12 months using Early Morning Collections of malaria vectors and 30-minute WHO bioassays. Resistance to pyrethroids and OPs was assessed by detecting the frequency of L1014F and L1014S kdr mutations and Ace-1(R)G119S mutation, respectively. Blood meal origin was identified using a direct enzyme-linked immunosorbent assay (ELISA). The combination of Inesfly 5A IGR™ and LLINs was effective in killing 99.9-100% of malaria vector populations for 6 months regardless of the dose and volume treated. After 12 months, mortality rates decreased to 69.5-82.2%. The highest mortality rates observed in houses treated with 2 layers of insecticide paint and a larger volume. WHO bioassays supported these results: mortalities were 98.8-100% for 6 months and decreased after 12 months to 81.7-97.0%. Mortality rates in control houses with LLINs were low. Collected malaria vectors consisted exclusively of Anopheles coluzzii and were resistant to pyrethroids, with a L1014 kdr mutation frequency ranging from 60 to 98% through the study. About 58% of An. coluzzii collected inside houses had bloodfed on non-human animals. Combining Inesfly 5A IGR™ and LLINs yielded a one year killing efficacy against An. coluzzii highly resistant to pyrethroids but susceptible to OPs that exhibited an anthropo-zoophilic behaviour in the study area. The results obtained in a real setting supported previous work performed in experimental huts and underscore the need to study the impact that this novel strategy may have on clinical malaria and malaria exposure in children in a similar area of high pyrethroid resistance in South-Western Burkina Faso
