In their words: connecting on-line weblogs to developmental processes.

This paper seeks to connect adolescents' communication within on-line weblogs or blogs to developmental processes. A total of 195 English language blogs written by self-identified 14- to 18-year-olds were selected; three entries from each blog were analysed, resulting in a sample of 585 entries. Blogger demographics, self-presentation, and blog entries (format, style, content, and tone) were coded. The blog authors in our sample were overwhelmingly female and lived within the US; the majority were between 15- and 16-years of age. Bloggers utilized usernames and userpictures for self-presentation and in addition to gender, frequently presented information about their age and location. The majority of the entries used text, were narrative and reflective in style, and contained themes related to their authors' peers and everyday life. Emotional tone was present and entries with romantic, identity, and future-related themes often contained emotional tone. Blog authors seemed to be using blogs to create narratives and to reflect about the people and events in their lives. Our results show that adolescent bloggers project off-line themes to their blogs, suggesting that their on-line and off-line contexts are psychologically connected.

Leaked Draft Has Rich Nations Dominating Climate Protocol [The Primate Diaries]


Kyoto would be replaced with a protocol run by the World Bank, says Guardian.

The Guardian newspaper last night published a leaked draft of a climate agreement entitled only Draft 271109 but known as the "Danish Text" by UN delegates in Copenhagen. The revelation has driven a wedge between rich and poor nations as the draft proposal makes significant changes to the Kyoto Protocol and would place undue pressure on developing nations who had little to no role in the climate crisis to begin with.

As The Guardian's John Vidal reported from the UN Climate Change Conference:

The so-called Danish text, a secret draft agreement worked on by a group of individuals known as "the circle of commitment" - but understood to include the UK, US and Denmark - has only been shown to a handful of countries since it was finalised this week.

The agreement, leaked to the Guardian, is a departure from the Kyoto protocol's principle that rich nations, which have emitted the bulk of the CO2, should take on firm and binding commitments to reduce greenhouse gases, while poorer nations were not compelled to act. The draft hands effective control of climate change finance to the World Bank; would abandon the Kyoto protocol - the only legally binding treaty that the world has on emissions reductions; and would make any money to help poor countries adapt to climate change dependent on them taking a range of actions.

The document was described last night by one senior diplomat as "a very dangerous document for developing countries. It is a fundamental reworking of the UN balance of obligations. It is to be superimposed without discussion on the talks".

فجر المجرات في حقل هابل العميق



متى تكونت المجرات؟ للوصول للإجابة، تم التقاط أعمق صورة للسماء في الأشعة تحت الحمراء القريبة إلى الآن. الصورة هي لنفس الحقل الذي تم تصويره في الضوء المرئي عام 2004 وسمي بحقل هابل المتناهي العمق (HUDF). تم التقاط الصورة خلال الصيف الفارط باستخدام الكاميرا واسعة النطاق 3 المثبته حديثا على تلسكوب هابل الفضائي بعد عملية الترميم الأخيرة. بعض اللطخات الحمراء في الصورة تتجاوز درجة 8 في انحيازها الأحمر، ويرجح أنها مجرات وجدت في وقت كان فيه عمر الكون بضعا بالمائة من العمر الحالي، حتى أنها يمكن أن تكون ضمن مجموعة المجرات البدائية. تظهر الصورة كذلك بعض المجرات الحديثة الملونة في واجة الصورة. حسب تحليلات فريق حقل هابل المتناهي العمق (HUDF09)، تبين أن بعض هذه المجرات البدائية تحتوى على قدر ضئيل من الغبار البين-نجمي. هذا القسم من المجرات الخافتة احتوى في الماضي نجوما عالية الطاقة بعثت ضوءا كان له تأثير على قدر كبير من المادة العادية المتبقية في الكون، وتحويلها من غازات باردة إلى بلازما متأنية.
