The prognostic value of a new lef t bundle branch block in patients with acute myocardial infarction: A systematic review and meta-analysis
No full textObjective: To assess the prognostic value of new left bundle branch block (LBBB) in patients with acute
myocardial infarction (AMI). Background: LBBB develops in many cardiac conditions, including AMI. The empirical evidence for the contribution of LBBB to mortality in AMI is not consistent.
Methods: Medline, PubMed, CINAHL, and EMBASE were searched. Inverse variance meta-analysis was performed with odds ratios as the effect estimates. The I 2 statistic and risk of bias were assessed.
Results: Eight studies involving 105,861 participants were eligible. New LBBB was associated with higher mortality at 30 days (OR: 2.10, 95% CI 1.27 to 3.48) and 1-year follow up (OR: 2.81, 95% CI 1.64 to 4.80), and increased heart failure risk (OR: 2.64, 95% CI 1.84 to 3.77). Conclusions: AMI patients with new LBBB are a high risk group and must be treated accordingly. Yet, more research is needed given the limitations of studie
الإطار القانوني الناظم للمياه الجوفية في القانون الدولي: دراسة تطبيقية على المياه الجوفية الفلسطينية
No full textمقالة محكمةتأتي هذه الدراسة لتسليط الضوء على القواعد القانونية الدولية، الاتفاقية والعرفية، التي يجب أن تطبق على مصادر المياه المشتركة بين الفلسطينيين والإسرائيليين وخاصة الجوفية منها. وطالما أن قضية المياه من المسائل العالقة بين الجانب الفلسطيني ودولة الاحتلال الإسرائيلي، وما زالت معظم مصادر المياه في فلسطين تحت سيطرة الاحتلال الإسرائيلي، وبشكل خاص الجوفية منها، دون مراعاة حصة الفلسطينيين في هذه المصادر، أو النظر لاحتياجات الشعب الفلسطيني المائية المتزايدة، فقد جاءت هذه الدراسة لمعالجة النواحي القانونية التي تنظم المياه الجوفية في القانون الدولي العام، والقانون الدولي الإنساني، ومحاولة إسقاطها على حالة الصراع الفلسطيني- والاحتلال الإسرائيلي، لاستخلاص مبادئ قانونية صالحة لحسم المسألة محل البحث. وعليه، قمنا بتقسيم هذا البحث إلى أربعة مطالب رئيسة، بحيث تناولنا فيها المصادر المائية الفلسطينية، والوضع القانوني للمياه في فلسطين، باعتبارها ثروة طبيعية في إطار مبادئ القانون الدولي والاتفاقيات الثنائية بين منظمة التحرير الفلسطينية ودولة الاحتلال الإسرائيلي، ومدى انطباق المبادئ القانونية الدولية على المياه الجوفية بين الفلسطينيين والاحتلال الإسرائيلي.
وتوصلت الدراسة إلى جملة من الاستنتاجات والمقترحات كفيلة بمساندة المفاوض وصانع القرار الفلسطيني في المرحلة المقبلة من الصراع، بما يخدم بسط السيادة الفلسطينية على المصادر المائية الوطنية وفقًا للقانون
Urban acupuncture and the ecological transportation hub, Ramallah, Palestine
No full textUrban Acupuncture, a term foiled by Barcelonan
architect and urbanist Manuel de Sola Morales,
aims at identifying weak or sensitive spots in the
city that are left untreated or marginalized in terms
of social, economic and ecological factors. Those
spots are then treated using urban acupuncture by
developing small scale alternatives to help release
the stress of the city, similar to that of traditional
Chinese acupuncture, and by that creating a rebel
effect that functions on a larger urban context. [1]
This project will address the identification of the
one of several parcels of public lands of the city of Ramallah for the design of an ecological public
transportation hub within the existing city fabric. This parcel shall function as a part of the series of
spots selected within the city in order to achieve a sustainable urban environment.
Using the GIS data present about the transportation of the city of Ramallah, the types of lands, and
their locations will help us in pinpointing the main spot for the transportation hub in the city that can
be of use to our study. “GIS helps highlight the transportation system's reach, coverage, modal
relationships, key corridors, and relationship to our nation's economic activity and environment”.

No full textThe analytical scheme used in the project The Evolution of the
Discourse of School Mathematics (EDSM) was developed to
analyse the change over time in examination texts. An adapted
version of the EDSM scheme has been deployed to analyse the
nature of mathematics construed in Palestinian schools’ textbooks
and the mathematical activity expected of students in the
geometry textbooks for students aged 10 to 16 years. The
adaptation includes adding further tools for analysing visual
components of texts, as well as accounting for some differences
between English and Arabic. This article outlines these
adaptations and illustrates the use of the adapted scheme with a
different genre of texts from those studied in the EDSM project.
Some of the challenges in the adaptation process in relation to
Arabic mathematics discourse are discusse

The influence of corporate governance on corporate performance: evidence from Palestine
No full textThe objective of this study is to explore the relationship between
corporate performance and corporate governance by companies listed on the
Palestinian Stock Exchange. Accounting and market performance measures
were used to proxy corporate performance. Corporate governance represented
by the board of directors’ size, the frequency of the annual meetings of the
board, existence or otherwise of an audit committee, institutional investors
ownership and foreign ownership. To achieve the objective of the study, all
non-financial companies listed on the exchange and published their annual
reports during the period between 2010 and 2012 were used. The result of the
analysis revealed that corporate performance is negatively associated with
corporate governance. This implies that the result is inconsistent with agency
theory. This might be due to the fact that corporate governance in Palestine is
still at its infancy stage
