Iron status: a possible risk factor for the first febrile seizure.

Abstract: Summary: Purpose: We conducted a controlled study to investigate the relation of iron status and first febrile seizure (FFS). Methods: Measures of iron sufficiency including hemoglobin concentration (HB), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and plasma ferritin (PF) were prospectively measured in 75 children with FFS and compared with 75 controls matched for age and sex with febrile illnesses without convulsions. Results: Mean ferritin level was significantly lower in cases with FFS (29.5 ± 21.3 μg/L) than in controls (53.3 ± 37.6 μg/L) with p = 0.0001. The proportion of subjects with a PF level ≤30 μg/L was significantly higher among children with FFS (49 of 75 vs. 24 of 75) than in controls (p = 0.000). Mean levels of HB, MCV, and MCH also were lower among FFS cases, but differences failed to attain statistical significance. A higher proportion of cases with FFS had an HB <110 g/L, MCV <72 fL, and MCH <24 pg than did the controls, but the differences were not statistically significant. There were no statistically significant differences between the cases and the controls in the mean peak temperature on admission, types of underlying illness, or family history of epilepsy and of febrile convulsion. Conclusions: PF level was significantly lower in children with FFS than in the reference group, suggesting a possible role for iron insufficiency in FFS.

A study of the effects of preprocessing strategies on sentiment analysis for Arabic text

Abstract: Sentiment analysis has drawn considerable interest among researchers owing to the realization of its fascinating commercial and business benefits. This paper deals with sentiment analysis in Arabic text from three perspectives. First, several alternatives of text representation were investigated. In particular, the effects of stemming, feature correlation and n-gram models for Arabic text on sentiment analysis were investigated. Second, the behaviour of three classifiers, namely, SVM, Naive Bayes, and K-nearest neighbour classifiers, with sentiment analysis was investigated. Third, the effects of the characteristics of the dataset on sentiment analysis were analysed. To this end, we applied the techniques proposed in this paper to two datasets; one was prepared in-house by the authors and the second one is freely available online. All the experimentation was done using Rapidminer. The results show that our selection of preprocessing strategies on the reviews increases the performance of the classifiers.

Tomato Root and Shoot Responses to Salt Stress Under Different levels of Phosphorus Nutrition

Abstract: Crops differ in their ability to grow under saline conditions and their responses are quite variable and not fully understood. This study was conducted to evaluate the root and shoot responses of tomato to salt stress conditions under different levels of phosphorus (P) nutrition. Tomato seedlings (cv Riogrande) were grown in 500 mL glass jars containing Hoagland's solutions which were salinized by four levels of NaCl salt (0,50,100, and 150 mM NaCl) and/or enriched with three P levels (0.5,1, and 2 mM P) making nine combination treatments. Plants were harvested at the vegetative growth stage and data were collected for root and shoot characteristics. The results indicate that increasing salinity stress was accompanied by significant reductions in shoot weight, plant height, number of leaves per plant, and a significant increase in leaf osmotic potential and peroxidase activity regardless of the level of P supplied. Both root length and root surface area per plant were decreased significantly unde...

The impact of leadership styles on nurses' satisfaction and intention to stay among Saudi nurses.

Abstract: abualrub r.f. & alghamdi m.g. (2012) Journal of Nursing Management 20, 668–678 The impact of leadership styles on nurses’ satisfaction and intention to stay among Saudi nurses Aim To examine the impact of leadership styles of nurse managers on Saudi nurses’ job satisfaction and their intent to stay at work. Background Increasing nurses’ satisfaction is one of the key elements in meeting challenges of quality outcomes, patient satisfaction and retention of staff nurses in hospitals. Methods This study used a descriptive correlational design. The Multifactor Leadership Questionnaire (MLQ-5X), Job Satisfaction Survey (JSS), the McCain’s Intent to Stay Scale and a demographic form were used to collect the data from a convenience sample of 308 Saudi nurses. Results Saudi nurses were moderately satisfied in their jobs. In addition, nurses were more satisfied with leaders who demonstrated transformational leadership styles, and those who were more satisfied with their jobs intended to say at work. The background variables, the transformational leadership style and the transactional style explained 32% of the variation in job satisfaction. Conclusions The results of the study emphasized the importance of transformational leadership, which indicates the need for further attention to training and development of effective leadership behaviours. Implications for nursing management Nurse administrators in Saudi Arabia should capitalize on the importance of transformational leadership style in enhancing the level of job satisfaction.
