Proactive and reactive styles of palestinian presidents leadership in times of crisis

Crises are unavoidable which makes response an imperative matter. Thus, the proactive style becomes an indispensable part of the readiness and preparedness in any potential crisis and can help prevent it. Besides, the reactive style is still important to deal effectively with a crisis especially regarding its recovery. Proactive and reactive styles were needed by Palestinian Presidents due to the occurrence of various crises faced by them. This study examines both proactive and reactive styles used by the Palestinian Presidents leadership during crisis. Besides, it examines how the Palestinian Presidents used these styles to deal with different crises at different times. This study used content analysis on the news stories from the New Straits Times. A total of 313 stories from1996 to 2016 pertaining to proactive and reactive styles used by Palestinian Presidents were found. The stories that included reactive style figured 67.7%, while the stories that included proactive style totaled 32.3%. For President Arafat, a total of 63% of the stories included reactive style compared to 37% of the stories that included proactive style. For President Abbas, a total of 78.4% of the stories contained reactive style compared to 21.6% that contained proactive style. Proactive style has been used only in political crises, while reactive style has been used in all crises. Providing various scenarios in dealing with crises allows other organizations and individuals to be initiative in dealing with any similar future crises. This study serves as a guideline for choosing proper prospective measures and responses to crises.

The impact of turbulence and phytoplankton dynamics on foam formation, seawater viscosity and chlorophyll concentration in the eastern english channel

The space-time dynamics of chlorophyll a concentration and seawater excess viscosity has been investigated in the hydrographically contrasting inshore and offshore water masses of the eastern English Channel. This was done during the phytoplankton spring bloom dominated by Phaeocystis globosa before and after the very large-scale formation of foam induced by an increase in wind-driven turbulence and the related wave breakings. The results suggest that the dynamics of chlorophyll a concentration and seawater excess viscosity are differentially controlled by the formation of foam through the intensity of the spring bloom and wind-generated turbulence.

A neuropharmacological profile of lycium schweinfurthii (solanaceae) methanolic extract in mice

Lycium schweinfurthii is a shrub belonging to the Solanaceae family which widely grows in North Africa and Mediterranean regions. The plant leaves have traditionally been used for gastrointestinal diseases as peptic ulcer in Libya. This study aimed to investigate the effect of Lycium schweinfurthii extract on the central nervous system in mice including anticonvulsant, antidepressant and muscle relaxant activities. The methanolic extract was prepared by fractionation technique. Albino male mice weighing 22 ± 2.0 gm were used and equally divided into equal number and weight for each experiment (n = 6). The best effective pharmacologically dose of 400 mg/kg, i.p. of the methanolic extract was selected to explore the anticonvulsant activity for picrotoxin-induced convulsion in mice (5.0 mg/kg), antidepressant activity of forced swimming test of depression and muscle relaxant action by motor coordination test of hanging wire. Fluoxetine (10.0 mg/kg), imipramine (15.0 mg/kg) and diazepam (5.0 mg/kg) were used as reference compounds. Lycium schweinfurthii extract exhibited a significant prolonged delay in the onset time of induced convulsion and significant decrease in the frequency of convulsion as well as a significant decrease in the duration time of attacks. Pretreatment with flumazenil (2.0 mg/kg) was found to increase the frequency and duration of convulsions without profound change in the onset time produced by Lycium schweinfurthii. For antidepressant activity, the plant leave extract significantly decreased immobility time duration without a muscle relaxant effect. The results suggest that the methanolic extract of Lycium schweinfurthii leave has anticonvulsant and antidepressant-like activities without any muscle relaxant effect in mice. Thus, Lycium schweinfurthii may have a neuropharmacological potential use in human.

Tunisian maturity-onset diabetes of the young: a short review and a new molecular and clinical investigation

Introduction/aims: Maturity-Onset Diabetes of the Young (MODY) is a monogenic non-autoimmune diabetes with 14 different genetic forms. MODY-related mutations are rarely found in the Tunisian population. Here, we explored MODY related genes sequences among seventeen unrelated Tunisian probands qualifying the MODY clinical criteria. Materials and methods: The GCK and HNF1A genes were systematically analyzed by direct sequencing in all probands. Then, clinical exome sequencing of 4,813 genes was performed on three unrelated patients. Among them, 130 genes have been reported to be involved in the regulation of glucose metabolism, β-cell development, differentiation and function. All identified variants were analyzed according to their frequencies in the GnomAD database and validated by direct sequencing. Results: We identified the previously reported GCK mutation (rs1085307455) in one patient. The clinical features of the MODY2 proband were similar to previous reports. In this study, we revealed rare and novel alterations in GCK (rs780806456) and ABCC8 (rs201499958) genes with uncertain significance. We also found two likely benign alterations in HNF1A (rs1800574) and KLF11 (rs35927125) genes with minor allele frequencies similar to those depicted in public databases. No pathogenic variants have been identified through clinical exome analysis. Conclusions: The most appropriate patients were selected, following a strict clinical screening approach, for genetic testing. However, the known MODY1-13 genes could not explain most of the Tunisian MODY cases, suggesting the involvement of unidentified genes in the majority of Tunisian affected families.

Performance analysis of first order digital sigma delta adc

Ever-growing era of mobile and personal wireless networks, motivated research in several fields of engineering resulted in low power and low cost consumer products. The voice band processing required in mobile applications demand for architectures, which can easily be integrated in single chip SoC applications. The conventional approach is to have a dedicated IC outside the digital ICs to perform analog to digital conversion. The motivation of single chip radios demand for integration of such ADC modules on digital cellular related ICs. Mixed signal design is very challenging and hence usually it is preferred to have separate ADC chip before the ASIC/FPGA. In this paper we present a digital sigma delta ADC architecture, which can perfectly be integrated in any digital IC with a targeted sampling rate of 20 kS/s with more than 80 dB dynamic range.

Online interviews for qualitative health research in africa: a scoping review

Online interviews can be powerful tools in global health research. In this article, we review the literature on the use of and challenges associated with online interviews in health research in Africa and make recommendations for future online qualitative studies. The scoping review methodology was used. We searched on Medline and Embase in March 2022 for qualitative articles that used internet-based interviews as a data collection method. Following full-text reviews, we included nine articles. We found that online interviews were typically conducted via Microsoft Teams, Zoom, Skype, WhatsApp, Facebook Messaging and E-mail chats. Online interviews were used in Africa because of the restrictions imposed by the coronavirus disease 2019 pandemic and the need to sample participants across multiple countries or communities. Recruitment for online interviews occurred online, interviews were characterised by inaudible sounds, the inability to use video options and the challenges of including people with low income and education. We recommend that researchers critically evaluate the feasibility of online interviews within a particular African locality before fully implementing this data collection approach. Researchers may also collaborate with community-based organisations to help recruit a more socioeconomically diverse sample because of the potential of excluding participants with limited internet access.

Bioefficacy of insecticide against tur pod bug, clavigralla gibbosa (spinola) on pigeonpea [cajanus cajan (l.) millsp.]

Pod sucking bugs are the key impediments for the low productivity in India. Nymphs and adults of tur pod bug, Clavigralla gibbose (Spinola) suck the cell sap from the pods and cause loss of the grain. Because of its high fecundity and wide host adaptability, it is necessary to check its damage potential. For this purpose, an experiment on bioefficacy of insecticides against this insect was conducted in the laboratory-cum-field conditions on cultivar “Paras” during kharif season 2010-11, 2011-12 and 2012-13. Eight insecticides viz., endosulfan 35EC, monocrotophos 36SL, chlorpyriphos 20EC, quinalphos 25EC, triazophos 40EC, decamethrin 2.8EC, fenvalerate 20EC and cypermethrin 25EC were selected based on their LC50 values against this insect. Among the tested insecticides, cypermethrin proved most toxic (63.94 times) against adults of C. gibbosa followed by decamethrin. Quick knock down effect of decamethrin and fenvalerate was recorded in the field conditions. Therefore, the combinations of decamethrin and quinalphos with DDVP (76 EC) were also tested under field conditions. Cypermethrin, decamethrin plus DDVP, decamethrin and monocrotophos were found effective in managing the C. gibbose population upto 10 days after application. None of the insecticides could manage the bug population below ETL after 14 days of their application. Application of cypermethrin @ 188 mL ha-1 recorded the highest grain yield, highest net monetary returns and highest incremental cost benefit ratio, followed by decamethrin, fenvalerate and monocrotophos. Either of dimethoate or oxydemeton methyl could also manage the bug population

The influence of employee empowerment on employee job satisfaction in five-star hotels in jordan

This paper examines the influence of empowerment on job satisfaction in five-star hotels in Jordan. The influence of empowerment on job satisfaction remains a relatively unexplored area. A 52-item questionnaire, measuring empowerment and job satisfaction, was distributed to 332 employees in 12 five-star hotels in Jordan with a 56% response rate. Principal components analysis determined the factor structure and regression analysis determined the influence of empowerment on job satisfaction. The results revealed both structural and psychological empowerment have significant individual influences on job satisfaction, but more significant when structural and psychological empowerment are combined. Most of previous studies were conducted in western economies and little in the Middle East generally and Jordan in particular. This research contributes to the literature by including both dimensions of empowerment where previous scholars used only one.

Banana (Musa spp.) are giant perennial grasses, commonly known as ‘Apple of paradise’.The chromosome counting of Elachi, Poovan and Nendran Banana traits were recorded. In average, a number of chromosomes recorded in Poovan (13.2), followed by Elachi with 11.1 chromosomes and Nendran with 10.9 chromosomes. There are various methods of determining banana ploidy level, one among is estimating stomatal density and size. The present investigation Elachi, Nendran and Poovan stomatal density range from 50 to 55/mm2 which are diploid, while Robusta ranges 34/mm2 which is triploid. Highest stomatal size recorded in Poovan traits (48 μm2) followed by Robusta (45 μm2), Nendran (28 μm2) and Elachi (21 μm2). Another method of ploidy determination is by chloroplast count in a guard cell of stomata. Elachi, Nendran, and Poovan contain 8 chloroplasts in the guard cell thus belongs to diploid. In the analysis of floral characters of all the four traits reveals that there is no significant difference in stigma length and width. Similarly, no significant variation recorded in anther length. Pollen size is often used as a biological parameter to estimate the ploidy and viability of mature pollen grains. Broad variation in pollen viability exists among clones with Musa species. Mycorrhizal association with the higher plants has also shown an increase in agricultural productivity. The percent colonization of AMF with the root system was calculated by two methods. Compare to Method – I and Method – II reveals that in Elachi 2.5%, Poovan 13.3% and 17.5% of variations recorded. Overall in the average highest percent of colonization were recorded in Poovan (76.6%).

Comparative analysis of machine learning classification models in predicting cardiovascular disease

For a long time, cardiovascular diseases have been the leading cause of death worldwide. Machine learning has found significant usage in the medical field as it can find patterns in data. Classification models can help cardiologists to diagnose heart diseases and minimize misdiagnosis accurately. In this paper, we explored a dataset related to heart disease and compared the accuracy of 43 machine learning classification models. The dataset for this research was downloaded from Kaggle; it contained 1190 observations, 11 features (age, sex, chest pain type, resting blood pressure, serum cholesterol, fasting blood sugar, resting electrocardiogram results, maximum heart rate achieved, exercise induced angina, oldpeak, the slope of the peak exercise ST segment) and a binary target variable (no heart disease or observed cardiovascular disease). For data exploration, preprocessing, training, testing, and predictor importance analysis, we used MATLAB R2004a software and the Classification Learner app included in this software. Before training machine learning classification models, we divided the dataset into a training set (90% of observations) and a test set (10% of observations). To prevent overfitting during the training of classification models, 10-fold cross-validation was used. The result showed that the best accuracy was reached with an optimized ensemble classification model (validation accuracy: 0.9262 and test accuracy: 0.9580). After calculating the permutation importance of each feature, we observed that the most important feature among all 11 features was the slope of the peak exercise ST segment.

A human study on the effect of alhagi maurorum (camel thorn) on patients suffering from hepatitis b virus

Hepatitis B virus infection is a major health problem worldwide. More than 400 million people are suffering from this infectious disease. Alhagi Maurorum (camel thorn, CTE) is used in Libyan folk medicine for hepatitis. The aim of this study is to investigate the effect of the camel thorn on the hepatitis B virus. After a pharmacological and toxicological screening of camel thorns on experimental animals in our laboratories, in an open-label study, 15 patients of either gender were chosen at random with their consent (consent form signed). The patients had no liver cirrhosis and were not alcoholics. Following clinical testing, the patients were given a low, safe dose of camel thorn powder (2.6 g soaked in boiling water for 10 minutes) three times per day for six months. The viral load was measured before treatment and three and six months after the beginning of the experiment by polymerase chain reaction. The complete blood picture, the level of transaminases, bilirubin, creatinine, blood glucose, lipid profile, thyroid function, and prothrombin were assessed before and after three months after the beginning of the experiment. Our data showed no significant changes in the complete blood picture, creatinine, blood urea, glucose level, bilirubin, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, lipid profile, prothrombin, and thyroid function. The levels of viral load before, three months after, and six months after the beginning of our study were 1689 ± 289, 558 ± 160, and 271 ± 026 IU per mL, respectively. From this study, we may conclude that the camel thorn is safe and showed activity against viral hepatitis B, however, further investigations are needed by increasing the number of patients and using higher doses of plant extract to explore its mechanism of action. Finally, the mechanism of camel thorn may be related either to its antiviral effect or to the stimulation of either endogenous interferon or the immune system.
