Mr. Gonzi's victory; was the contest necessary?

PM in Marsascala during his tour for support
In todays The Times one can read that PM Lawrence Gonzi gained 96,5 per cent of the vote in the PN leadership contest. It gives The Observer a flashback from the sixties when Leonid Brezhnev gained 105 per cent of the vote in former Soviet Union. That is what can be called a good and fair election! To avoid any misunderstanding; of course yesterday's election can not be regarded otherwise than fair. But was it necessary? Even if Mr. Gonzi felt that he needed to have his leadership confirmed, the outcome of the vote is still not a true and fair view on the situation in The Nationalist Party since Mr. Gonzi was the only candidate. Say for instance that Mr. Debono had challenged Mr. Gonzi regarding the leadership (he has challenged him about almost everything else). Of course Mr. Gonzi would not have gained 96,5 per cent of the vote. That is as certain as it is that Mr. Debone would have lost such a debacle. Mr. Debono has previously tried very hard to commit political suicide and if he had challenged Mr. Gonzi regarding the leadership he would surely have succeeded. One can wonder if all this really was necessary. Mr. Gonzi is the undisputed leader of the Nationalist Party no matter what Mr. Debono tries to do. Even if there are a number of opponents to Mr. Gonzi in the party they are not as stupid as to challenge Mr. Gonzo in this political situation. They would, in that case, have gone down together with Mr. Debono.

Minecraft "Minecrack" Review

Minecraft or as I prefer to call it “Minecrack” is a game that was recently recommend to my by a friend. At first glance the game looks like a throwback to the original Atari or Nintendo game systems (think Mario Bros type graphics minus having to jump on walking mushrooms) The game essentially has the look of a giant Lego world consisting entirely of blocks, the animals, trees, even the water are all blocks. There’s also no set point system or objective you have to reach in order to beat the game. But despite this the game is exceptionally addictive. I personally found it very easy to spend a few hours on it before I realized how much time had gone by.

Minecraft 1.8 Review

For those eagerly waiting for the first half of the first half of the Mincraft adventure update, the wait is finally over. And no I’m not talking about some buggy pre release that is a pain in the ass to properly install that’s been out for just over a week prior. As of Sept 14 it’s available to the masses who are looking to feed their “minecrack” addiction........... Because of the recent changes I figured it was time for an updated Minecraft review covering some of the recent changes. This is not a complete review on the 1.8 adventure update, just what I’ve seen and experienced in the game so far to give you an idea what to expect..........

SocialConnect

SocialConnect is the only Joomla extension that allows you to integrate your Joomla site with social networks and identity providers for user authentication, posting content directly to social networks and 3rd-party comment system integration.

Features

Let your users register to your website with their social profile from Facebook, Twitter, Google, LinkedIn, Github, WordPress.com, Microsoft (Outlook.com, Hotmail, SkyDrive, Windows Live, Windows Phone & Xbox Live), Amazon, Disqus, Foursquare, Instagram, StackExchange, SoundCloud & Tumblr.

AutoPost to Facebook, Twitter & LinkedIn right from the Joomla article or K2 item edit forms!

Add Facebook Open Graph and Twitter Card tags on each K2 item or Joomla article to make your content even more social media ready.

Enable Disqus or Facebook comments on your K2 items, Joomla articles, Virtuemart or RedShop product pages.

Avatars for your users from their social profile, K2 or Gravatar.com

Better login and registration pages, with multiple layouts to choose from. Users also get a customizable landing page after login.

Easily check how many concurrent users browse your site and see who's logged into your site and from which social network.

Easy to configure with a simple, yet elegant "status" dashboard in Joomla's backend.

Use the SocialConnect Twitter module to display one ore more streams of tweets for any Twitter account & style it the way you want, unlike the official Twitter widget which is too "design restrictive" when it comes to embedding.

 

Beautiful & customizable frontend

SocialConnect comes with a set of predefined layouts to use right out of the box - or customize anyway you like. Consistency between the component & module layouts make your user "not think" and thus easier to engage with your e-shop, forum, community or other type of site that utilizes user engagement. Check out the available component and module layouts below for more.
NextPrev
  • Remember that ugly login page in Joomla? Now you can forget about it. A simple layout that can easily fit any Joomla template design - distinct blocks for the available user actions. Don't make your user think. Make it easy for them to join your site. The layout you see here is one of the 3 bundled with SocialConnect.
  • The second layout gives more focus to the registration process. Like the first layout, it allows you to have an optional descriptive text communicating to your users why they should sign up/register to your website.
  • The 3rd layout is a variation of the first one and it's ideal for single-column layouts. The optional welcome text in on the left of the sign-in block, while registration is at the bottom. Perfect for minimal designs or for clear focus on the registration/sign-in process.
  • Like the component, the SocialConnect module comes with 2 layouts as well. A compact layout that reveals the login/registration actions for your user, which can easily fit on your site's header or toolbar. The official K2 website uses the compact layout at the top-right.
  • ...And an "expanded" layout, ideal for using SocialConnect in the sidebar of your Joomla e-shop or forum. The layout is generic enough to easily fit any design. Maintaining a consistent login block across your site will not make your user wonder "where" they login when browsing through the pages of your site.
 

Integrates with all the major social networks

 
 

Post to Facebook, Twitter & LinkedIn 
right from the Joomla backend

Posting to Facebook, Twitter & LinkedIn just got easier. No need to use an external paid service like HootSuite or Buffer to cross-post your content to these social networks. No need to bother managing users for such services. Just have your content authors post directly from the Joomla article or K2 item edit forms directly to your social media accounts in Facebook, Twitter or LinkedIn. It's that simple!

SocialConnect v1.10.0 released

SocialConnect v1.10.0 is now available to download for subscribers. This new release improves compatibility with recent API changes in Facebook and LinkedIn.

Here's what's been added or changed in SocialConnect with the release of v1.10.0:

  • Facebook authorization in SocialConnect's settings will now render both your personal account as well as all Facebook Pages that you have access to (for posting content). Listing pages broke due to a recent change in Facebook's API. Additionally, all API calls will now use v2.12 of their API.
  • LinkedIn login and auto-posting now both use version 2 of the LinkedIn API - this also resolves auto-posting to LinkedIn failing because of the deprecation of version 1 of their API. Please keep in mind that posting directly to LinkedIn company pages is not yet allowed by the LinkedIn API.

To refresh your integration with either Facebook or LinkedIn, simply re-authorize your accounts from the SocialConnect settings.

As a reminder, 2 new options were added in the previous release (v1.9.0) under "Advanced Settings" ("Enforce HTTPS" & "Enforce absolute URL when posting to social") which address edge cases where social login failed (namely in sites behind CloudFlare that utilize "Flexible SSL") or auto posting failed (the shared URL was rendered relative instead of absolute).

 

DEMO

The JoomlaWorks website as well as the K2 website both utilize the latest release of SocialConnect.

Connecting the digital divides: Technology and cyber policy experts launch new journal

30 June 2015

Chatham House and Routledge, Taylor & Francis are launching the Journal of Cyber Policy on 2 July.

Fifteen years ago it would be unthinkable for cyber security to top the list of priorities at the annual US-China Security and Economic Dialogue, as it did last week. But, in the intervening years, cyber technologies and the internet have become fundamental tools for everything from running critical infrastructure such as energy grids and satellite systems, to political, economic and social interactions. Given the pace of change, it should not surprise us that we have barely started to understand how to govern this new order and manage the global internet in ways that both empower and protect us.

In response, Chatham House and Routledge (part of the Taylor & Francis Group) are launching the Journal of Cyber Policy, addressing a rapidly changing situation and connecting creative, technical and policy experts.

Informing the growing security challenges of an interconnected digital world, this new peer-reviewed journal will provide a valuable resource to decision-makers in the public and private sectors grappling with the challenges of cyber security, online privacy, surveillance and internet access. The journal will offer informed and rigorous thinking, supported by the journal’s internationally renowned editorial board.

'The Journal of Cyber Policy will empower experts with new thinking and diverse ideas delivered in a way which is practically relevant as well as academically rigorous,' Dr Patricia Lewis, research director, International Security Department at Chatham House and co-editor of the journal, said. 'It will change the game for those working on cyber issues.' 

'As the preferred publisher for think tanks around the world, we are proud to be Chatham House’s partner on this new journal, which seeks to address issues that touch upon all our lives on a daily basis,' said Leon Heward-Mills, Global Publishing Director (Journals) at Taylor & Francis Group.

The Journal of Cyber Policy launches on the evening of 2 July at a reception at Chatham House.

Editor's notes

Patricia Lewis, research director, International Security, Chatham House, is available for interview on cyber issues. To request an interview, please contact the press office.

Reflecting the global nature of cyber issues, the Journal of Cyber Policy is intent on drawing upon a geographically and culturally diverse set of contributors.

The editorial board includes:

  • Subimal Bhattacharjee, independent consultant on defense and cyber security issues, New Delhi (India)
  • Pablo Bello, secretary general, Asociación Iberoamericana de Centros de Investigación y Empresas de Telecomunicaciones (AHCIET) [and former vice minister of telecommunications] (Chile)
  • Dr Myriam Dunn Cavelty, lecturer for security studies and senior researcher in the field of risk and resilience at the Center for Security Studies, Zurich (Switzerland)
  • Prof Richard Dasher, director, US-Asia Technology Management Center, Stanford University (USA)
  • Dorothy Gordon, director-general, Ghana-India Kofi Annan Centre of Excellence in ICT (Ghana)
  • Alexandra Kulikova, programme coordinator, Global Internet Governance and International Information Security, PIR Center (Russia)
  • Dr Victoria Nash, deputy director, Oxford Internet Institute (UK)
  • Prof Motohiro Tsuchiya, professor, Graduate School of Media and Governance, Keio University (Japan)

Editor, the Journal of Cyber Policy: Caroline Baylon, Chatham House
Co-editors, the Journal of Cyber Policy: Dr Patricia Lewis and Emily Taylor, Chatham House

Topics for the first edition are as follows:

  • How did we get here?
  • Cyber crime – the impact so far
  • How does the internet run and who owns it?
  • Privacy vs security
  • Vulnerability and resilience of critical infrastructure
  • Cyber war is already underway
  • The next billion online
  • ​Cyber security awareness: Are politicians fit for purpose?
  • Internet of Things

The first two issues of the Journal on Cyber Policy will be published in 2016 and subscriptions to the journal can be placed in August 2015.

RNA helicase-regulated processing of the Synechocystis rimO-crhR operon results in differential cistron expression and accumulation of two sRNAs [Gene Regulation]

The arrangement of functionally-related genes in operons is a fundamental element of how genetic information is organized in prokaryotes. This organization ensures coordinated gene expression by co-transcription. Often, however, alternative genetic responses to specific stress conditions demand the discoordination of operon expression. During cold temperature stress, accumulation of the gene encoding the sole Asp–Glu–Ala–Asp (DEAD)-box RNA helicase in Synechocystis sp. PCC 6803, crhR (slr0083), increases 15-fold. Here, we show that crhR is expressed from a dicistronic operon with the methylthiotransferase rimO/miaB (slr0082) gene, followed by rapid processing of the operon transcript into two monocistronic mRNAs. This cleavage event is required for and results in destabilization of the rimO transcript. Results from secondary structure modeling and analysis of RNase E cleavage of the rimO–crhR transcript in vitro suggested that CrhR plays a role in enhancing the rate of the processing in an auto-regulatory manner. Moreover, two putative small RNAs are generated from additional processing, degradation, or both of the rimO transcript. These results suggest a role for the bacterial RNA helicase CrhR in RNase E-dependent mRNA processing in Synechocystis and expand the known range of organisms possessing small RNAs derived from processing of mRNA transcripts.

Crystallographic and kinetic analyses of the FdsBG subcomplex of the cytosolic formate dehydrogenase FdsABG from Cupriavidus necator [Molecular Biophysics]

Formate oxidation to carbon dioxide is a key reaction in one-carbon compound metabolism, and its reverse reaction represents the first step in carbon assimilation in the acetogenic and methanogenic branches of many anaerobic organisms. The molybdenum-containing dehydrogenase FdsABG is a soluble NAD+-dependent formate dehydrogenase and a member of the NADH dehydrogenase superfamily. Here, we present the first structure of the FdsBG subcomplex of the cytosolic FdsABG formate dehydrogenase from the hydrogen-oxidizing bacterium Cupriavidus necator H16 both with and without bound NADH. The structures revealed that the two iron-sulfur clusters, Fe4S4 in FdsB and Fe2S2 in FdsG, are closer to the FMN than they are in other NADH dehydrogenases. Rapid kinetic studies and EPR measurements of rapid freeze-quenched samples of the NADH reduction of FdsBG identified a neutral flavin semiquinone, FMNH•, not previously observed to participate in NADH-mediated reduction of the FdsABG holoenzyme. We found that this semiquinone forms through the transfer of one electron from the fully reduced FMNH−, initially formed via NADH-mediated reduction, to the Fe2S2 cluster. This Fe2S2 cluster is not part of the on-path chain of iron-sulfur clusters connecting the FMN of FdsB with the active-site molybdenum center of FdsA. According to the NADH-bound structure, the nicotinamide ring stacks onto the re-face of the FMN. However, NADH binding significantly reduced the electron density for the isoalloxazine ring of FMN and induced a conformational change in residues of the FMN-binding pocket that display peptide-bond flipping upon NAD+ binding in proper NADH dehydrogenases.

Hematopoiesis is regulated by cholesterol efflux pathways and lipid rafts: connections with cardiovascular diseases [Thematic Reviews]

Lipid rafts are highly ordered regions of the plasma membrane that are enriched in cholesterol and sphingolipids and play important roles in many cells. In hematopoietic stem and progenitor cells (HSPCs), lipid rafts house receptors critical for normal hematopoiesis. Lipid rafts also can bind and sequester kinases that induce negative feedback pathways to limit proliferative cytokine receptor cycling back to the cell membrane. Modulation of lipid rafts occurs through an array of mechanisms, with optimal cholesterol efflux one of the major regulators. As such, cholesterol homeostasis also regulates hematopoiesis. Increased lipid raft content, which occurs in response to changes in cholesterol efflux in the membrane, can result in prolonged receptor occupancy in the cell membrane and enhanced signaling. In addition, certain diseases, like diabetes, may contribute to lipid raft formation and affect cholesterol retention in rafts. In this review, we explore the role of lipid raft-related mechanisms in hematopoiesis and CVD (specifically, atherosclerosis) and discuss how defective cholesterol efflux pathways in HSPCs contribute to expansion of lipid rafts, thereby promoting myelopoiesis and thrombopoiesis. We also discuss the utility of cholesterol acceptors in contributing to lipid raft regulation and disruption, and highlight the potential to manipulate these pathways for therapeutic gain in CVD as well as other disorders with aberrant hematopoiesis.

Here, we show that crhR is expressed from a dicistronic operon with the methylthiotransferase rimO/miaB (slr0082) gene, followed by rapid processing of the operon transcript into two monocistronic mRNAs. This cleavage event is required for and results in destabilization of the rimO transcript. Results from secondary structure modeling and analysis of RNase E cleavage of the rimO–crhR transcript in vitro suggested that CrhR plays a role in enhancing the rate of the processing in an auto-regulatory manner. Moreover, two putative small RNAs are generated from additional processing, degradation, or both of the rimO transcript. These results suggest a role for the bacterial RNA helicase CrhR in RNase E-dependent mRNA processing in Synechocystis and expand the known range of organisms possessing small RNAs derived from processing of mRNA transcripts.
