RESUMO

BACKGROUND: For youth in geopolitically at-risk environments, such as Palestine, the issues related to Internet overuse and addictions are complex. Youth residing in the occupied territories of Palestine as in other highly militarized zones have high levels of environmental stressors (e.g., militarization, poverty, lack of employment opportunities, cultural pressures, etc.) and few chemical or social outlets such as alcohol, intoxicants, and leisure activities. As such, the easily accessible and unrestricted opportunities for stress-reducing social contact of social media can lead easily to excessive and maladaptive Internet use. Therefore, interventions directly aimed at awareness and education on how to manage Internet use are critical for addressing these issues in high risk populations. AIMS: The purpose of the current study was to test the efficacy of a time-limited group training program aimed at improving social skills and reducing addictive Internet behaviors among university students. METHODS AND RESULTS: The sample consisted of 30 university students who self-reported high scores on an Internet addiction scale. Participants were randomly assigned to either wait list or treatment group (15 in each condition). Results demonstrated that using a social skills training program over an 8-week period improved the level of social skills and reduced addictive Internet behaviors significantly in those who experienced the intervention when compared with a wait list control group. CONCLUSIONS: These findings support the implementation of time limited training programs targeting social skills and addictive patterns of Internet use with university students identified with high levels of Internet addictive behaviors.

RESUMO

Abstract The haemostatic efficacy of different extract types of Satureja thymbra L., Thymbra spicata L. (Lamiaceae) and Verbascum fruticulosum Post. (Scrophulariaceae) was evaluated in this study via the Prothrombin time (PT) and Activated partial thromboplastin time (aPTT) analysis. Aqueous, methanol and ethanol extracts of the examined plant species leaves were prepared to a final concentration 50 mg/mL. In vitro PT and aPTT assays were conducted on normal platelet poor plasma blood samples by a digital coagulation analyzer. The obtained results revealed anticoagulation activity of all investigated plant species with observed variations among them. The aqueous and ethanol extracts of T. spicata as well as the aqueous extract of S. thymbra prolonged PT values significantly (p < 0.05). While, all V. fruticulosum extract types have had no significant effect on the PT values. The recorded aPTT data showed that all aqueous extracts have had a significant effect on the blood haemostasis as they increased aPTT values in all plant species under study. Out of which, both the ethanol and methanol extracts of T. spicata and methanol extract of S. thymbra showed similar effect. Of great concern, it was clearly noticed that the aqueous and ethanol extract of T. spicata and the aqueous extract of S. thymbra possess the strongest anticoagulation effect as they increased both PT and aPTT values significantly relative to the control (p < 0.05). The variable anticoagulation bioactivity among the studied plant species could be referred to the various solvents degrees of solubility of different phyto-constituents. Thus, the efficacy of the plant species extracts evaluation as anticoagulants or coagulants were related to the plant species and to the solvent of extraction.

Resumo A eficácia hemostática de diferentes tipos de extrato de Satureja thymbra L., Thymbra spicata L. (Lamiaceae) e Verbascum fruticulosum Post. (Scrophulariaceae) foi avaliada neste estudo pelo tempo de protrombina (TP) e tempo de tromboplastina parcial ativada (TTPa). Os extratos aquosos, metanólicos e etanólicos das folhas das espécies de plantas examinadas foram preparados para uma concentração final de 50 mg/mL. Os ensaios de TP e TTPa in vitro foram realizados em amostras normais de sangue, pobre em plaquetas, por um analisador de coagulação digital. Os resultados obtidos revelaram atividade anticoagulante de todas as espécies de plantas investigadas, com variações observadas dentre elas. Os extratos aquosos e etanólicos de T. spicata e o extrato aquoso de S. thymbra prolongaram significativamente os valores de TP (p <0,05). Entretanto, todos os tipos de extratos de V. fruticulosum não tiveram efeito significativo sobre os valores de TP. Os dados registrados do TTPa mostraram que todos os extratos aquosos tiveram um efeito significativo na hemostase do sangue, pois aumentaram os valores de TTPa em todas as espécies de plantas em estudo. Dos quais, ambos os extratos etanólicos e metanólicos de T. spicata e o extrato metanólico de S. thymbra mostraram efeito semelhante. De grande preocupação, notou-se claramente que os extratos aquoso e etanólico de T. spicata e o extrato aquoso de S. thymbra apresentam efeito anticoagulante mais forte, aumentando os valores de TP e TTPa significativamente em relação ao controle (p <0,05). A variável bioatividade anticoagulante dentre as espécies vegetais estudadas pôde ser referida aos vários graus de solventes de solubilidade de diferentes fitoconstituintes.

RESUMO

Resumo O objetivo deste estudo foi descrever os perfis de cultura organizacional e suas dimensões nos hospitais governamentais e não governamentais da Faixa de Gaza da Palestina. Trata-se de uma pesquisa transversal descritiva que envolveu 400 participantes de hospitais governamentais e não governamentais no período de junho a dezembro de 2018. A população de estudo incluiu todas as categorias de trabalhadores dos hospitais como médicos, enfermeiras, paramédicos e administradores. Cerca de 60% da amostra era do sexo masculino e 40% do feminino. A faixa etária da maior parte dos participantes situava-se entre 20 e 40 anos. Destes, 78,2% possuíam bacharelado ou pós-graduação, enquanto 17,9% possuíam apenas diploma de graduação ou níveis menores de formação. O tamanho amostral dos participantes foi diverso de acordo com os tipos e capacidades dos hospitais. O maior número de participantes foi de hospitais governamentais com 82,5%, enquanto 17,5% eram de hospitais não governamentais. Os perfis de cultura organizacional mais comuns nos hospitais da Faixa de Gaza foram a cultura de clãs e de hierarquia. Os hospitais não governamentais apresentaram médias superiores aos governamentais em todos os perfis de cultura organizacional. É recomendável o uso de uma abordagem abrangente da cultura organizacional de modo a estudá-la e perceber sua direção e tendência antes de se estabelecer novos procedimentos ou iniciativas.

Abstract The aim of the study was to describe the organizational culture types and their dimensions at the governmental and non-governmental hospitals in the Gaza Strip of Palestine. It was a descriptive cross-sectional study that involved 400 participants of the governmental and non-governmental hospitals in the period between June and December 2018. The target population included all the working staff categories at the hospitals as physicians, nurses, paramedics, and administrators. About 60% of the sample was male and 40% was female. Most of the participants' age was between 20-40 years. Of these, 78.2% were having bachelor's or higher degrees and 17.9% were having diplomas or lesser degrees. Participants' sample sizes were diverse according to the types and capacities of their hospitals. The highest number of participants was from governmental hospitals with 82.5%, while 17.5% was from non-governmental hospitals. The highest determined types of management in Gaza Strip hospitals were clan and hierarchy-oriented cultures. The non-governmental hospitals had higher means than the governmental ones in all the organizational culture types. The comprehensive approach of organizational culture is desired to study the organizational culture type and realize its direction and trend before establishing new procedures or initiative programs.

RESUMO

BACKGROUND: Unintended pregnancies can result in poorer health outcomes for women, children and families. Young people in low and middle income countries are at particular risk of unintended pregnancies and could benefit from innovative contraceptive interventions. There is growing evidence that interventions delivered by mobile phone can be effective in improving a range of health behaviours. This paper describes the development of a contraceptive behavioural intervention delivered by mobile phone for young people in Tajikistan, Bolivia and Palestine, where unmet need for contraception is high among this group. METHODS: Guided by Intervention Mapping, the following steps contributed to the development of the interventions: (1) needs assessment; (2) specifying behavioural change to result from the intervention; (3) selecting behaviour change methods to include in the intervention; (4) producing and refining the intervention content. RESULTS: The results of the needs assessment produced similar interventions across the countries. The interventions consist of short daily messages delivered over 4 months (delivered by text messaging in Palestine and mobile phone application instant messages in Bolivia and Tajikistan). The messages provide information about contraception, target attitudes that are barriers to contraceptive uptake and support young people in feeling that they can influence their reproductive health. The interventions each contain the same ten behaviour change methods, adapted for delivery by mobile phone. CONCLUSIONS: The development resulted in a well-specified, theory-based intervention, tailored to each country. It is feasible to develop an intervention delivered by mobile phone for young people in resource-limited settings.
