Police too quick to rule out work-related motive in Cartago-based journalist’s murder

first_img ColombiaAmericas 2011-2020: A study of journalist murders in Latin America confirms the importance of strengthening protection policies ColombiaAmericas Receive email alerts Reports Reporters Without Borders thinks the police were a bit hasty in ruling out a work-related motive in the murder of journalist Javier Darío Arroyave, whose body was found yesterday morning in his home in the southwestern city of Cartago. Reporters Without Borders is stunned by yesterday’s fatal stabbing of journalist Javier Darío Arroyave in Cartago, in the southwestern department of Valle del Cauca. Aged 41, Arroyave was news director of local radio station Ondas del Valle, a Caracol affiliate, and a correspondent for the national daily El Tiempo. He also did other work.His body was found in his home yesterday morning. He had been stabbed many times and his laptop had been taken. The police quickly ruled out any connection with his work as a journalist but Reporters Without Borders says this possibility should be investigated.“Arroyave got into trouble several times in the past with the local authorities for covering corruption cases involving municipal and departmental officials,” the press freedom organisation said. “Colombian journalists who dare to cover this kind of story run the risk of serious reprisals. Although Arroyave did not report getting any direct threats prior to his murder, the possibility of a work-related motive cannot be dismissed out of hand. It should be considered along with other possible theories.”Arroyave’s Ondas del Valle colleagues began to suspect something was wrong when he did not turn up for the morning news programme, in which he was supposed to take part, and when he did not answer repeated calls to his home. They discovered his body when they went to his home and a neighbour with a copy of his door key let them in.The police said he was stabbed in the chest and abdomen. Three individuals are believed to have participated in the murder, taking his laptop and a few other personal effects. But no sign of a break-in was reported. Cartago police chief Armando Burbano said he did not think the murder was linked to Arroyave’s journalistic activities.However, the Reporters Without Borders partner organisation in Colombia, the Foundation for Press Freedom (FLIP), pointed out that former Cartago mayor Luis Alberto Castro suspended local government advertising for Arroyave’s programme in 2005, criticising him for trying to implicate local politicians in corruption. Cartago is also reputed to be one of the bases of the Norte del Valle drug cartel, allegedly led by Diego “Don Diego” León Montoya Sánchez.If the work-related motive is confirmed, Arroyave will be the first journalist to be murdered this year in Colombia because of his work.

Did Evolution Create Genetic Proofreading?

first_imgProtein manufacture in the cell is such a critical operation, there are numerous error-checking mechanisms the cell uses to get it right.  One of the most amazing is the careful association of DNA codons with amino acids, and the “proofreading” or “spell checking” that ensures fidelity.  How could spell checking evolve?    Science Daily announced that “Scientists Find Early Evolution Maximized The ‘Spellchecking’ Of Protein Sequences.”  Sounds interesting.  What did they find?  The answer should be in the original paper in Science.1  There, Guo, Schimmel and others from Scripps Institute claim that they found homologies between the spell-checking domains of one of the enzymes responsible for linking transfer RNA (tRNA) codons with the appropriate amino acid.  In this case, it is the aminoacyl-tRNA synthetase for alanine, called AlaRS.  This particular synthetase has to distinguish alanine from two other similar amino acids, glycine and serine.  It does this through the use of additional factors or domains called AlaXps that “provide functional redundancy by capturing mischarged tRNAAla molecules that escape the embedded editing activities of AlaRSs.”2  In addition, a linker called C-Ala binds the error-correcting domains together.    The team found that most of the domains of AlaRS are “highly-conserved” (i.e., unevolved) in all three kingdoms of life – including the modular arrangement of AlaRS itself.  That makes sense, else we would all be dead.  In their wording, “strong selective pressure retains these editing activities throughout evolution.”  But they did find C-Ala is only loosely conserved.  From this they wove a story of how this spell checking arrangement came to be:This phylogenetic analysis implies that all three forms of AlaXp evolved in the ancestral community.  This phylogeny also suggests that AlaXp-II is derived from AlaXp-I.  The editing domain of ThrRS is closest to AlaXp-I, thus suggesting an early separation that split the original editing enzyme into two different specificities, one for tRNAThr and the other for tRNAAla.  Most importantly, the phylogenetic analysis indicates that the editing domain of AlaRS appeared concurrently with the ancient, most-developed, and largest free-standing editing enzyme, the C-Ala?containing AlaXp-II.  Thus, C-Ala may have been instrumental in bringing together editing and aminoacylation domains on one tRNA to ultimately (through fusion) create AlaRS (fig. S6). In the simpler words of the Science Daily summary, the results “show that two separate functions—alanine adding and editing—were joined together in a single enzyme during early evolution, in a way that greatly enhances these activities.  The findings provide a glimpse into how enzyme functions have evolved.”1.  Guo, Chong, Beebe, Shapiro, Yang and Schimmel, “The C-Ala Domain Brings Together Editing and Aminoacylation Functions on One tRNA,” Science, 7 August 2009: Vol. 325. no. 5941, pp. 744 – 747, DOI: 10.1126/science.1174343.2.  There are three classes of AlaXp.  “Three types (Ia, Ib, and II) of free-standing genome-encoded AlaXps are widely distributed in all three kingdoms of life and act in trans to clear tRNAAla mischarged with Ser or Gly (7, 8, 31, 32).  Type Ia AlaXp lacks the Gly-rich motif near the N terminus of the editing motif of type Ib and type II AlaXps (33).  However, unlike types Ia and Ib AlaXps that are composed of just the editing domain, type II AlaXp has the C-Ala domain (Fig. 1A).”They found no such thing.  They found living organisms with spell-checking and proofreading that works on a phenomenally accurate scale – much better than the output of professional typists.  Then they made up a story out of thin air about how the parts of the machinery were “brought together” during an evolutionary history that was never to be doubted.  They ignored the error catastrophe that would have brought life down to a crash before the proofreading was already working.  They expected us to believe that “selective pressure” acts like a designer substitute to work miracles.  And they expected us baloney-detectors to swallow their line as if they “found” how all this came about.  Don’t fall for it any more than if they compared engine parts from a Mazda and a Ford and told you they found a glimpse of how they emerged from the dirt, or if they compared the spell checking algorithms in Internet Explorer and Firefox and described how they had a common ancestor in an earthquake.    Selective pressure, remember, is nothing but a set of boundaries.  It is not a creative force.  It’s like the walls and hubs in a pinball game (see 07/14/2009 commentary).  None of the constraints keep the ball from dropping in the hole and bringing the game to a stop.  It takes an intelligent agent manning the flippers to win.    It’s time to remember Keith Wanser’s statement about evolutionary explanations.  “There is not one theory of evolution, but a body of opinions, speculations and methods for interpretation of observational facts so that they fit into the philosophy of naturalism.”  That is what you saw again here.  Until enough people call them on the carpet for this circular, question-begging tactic, it will go on and on, deceiving readers of science journalism that the Darwin Party diviners are succeeding in getting glimpses into a mythical materialistic past that produced something from nothing.  Spellchecking is something, all right, but nothing is nothing.(Visited 11 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Network Literacy Critical in New Information Era

first_imgA new information eraHour by hour, day after day, in workplaces all across this nation and the world, workers are hearing the term “social networking.”They’ve begun to understand that the old information order in which people interacted, taught, and learned exclusively in face-to-face encounters and through the printed word has changed. It’s been replaced or complemented by something radically different — virtual sources of knowledge and communication, accessible at the speed of light.They see their coworkers integrating social media tools — tweeting, posting to Facebook and blogging — into their everyday work. These early adopting colleagues have discovered that using these tools and techniques enables them to connect, share, and make deeper professional imprints among a wider circle of peers.Missing out? But how to begin?The people who haven’t started incorporating social media tools into their work sense they’re missing out on something — something lasting and significant — something big.They are anxious to take the critical first step. But how? How do they master all of this and make it work for them?In other words, how do they become network-literate — fluent in the skills that define communicating in the 21st century? How do they find the time? How do they avoid the perils widely associated with social networking — privacy infringement and copyright violation, to name only a couple? How do they convince their supervisors to encourage social networking as part of their plans of work and evaluate the impacts of their social media efforts?Military Families Learning Network Literacy Community of PracticeThe Military Families Learning Network Literacy Community of Practice was formed to provide professionals not only with the skills but also with the mindset to make optimal use of this new approach to communicating.Our main goal is to engage a broad learning network to help define a new kind of professional — a fully engaged, networked professional equipped not merely to survive in this new, highly competitive communication landscape but also to learn, teach, create, share, and build within both personal and professional networked communities.The times are calling on all of us to build deeply engaged, reciprocal relationships with those we serve, learn from, and create with. Simply learning how to use social media tools such as Twitter and Facebook to reach larger numbers of clients isn’t enough. We must learn to use these and other online tools to build two-way, even multi-party, collaborative relationships with our clients.This is why a big part of the Network Literacy effort will involve helping professionals become comfortable with online social networking tools and then to begin building and sustaining collaborative relationships within emerging networks.A critical first step will be learning how to help professionals gain sufficient levels of what networking visionary Thomas Vander Wal describes as social comfort, namely learning how to build networks in which participants not only feel comfortable among each other but also with the technological tools and subject matter.This is the charge of the Network Literacy effort: to build a new-model worker adequately equipped and inspired to use emerging networks to forge close, highly collaborative relationships with their clients.In the course of helping build this new working model, we hope to contribute something equally as significant: a powerful group of transformers, people who, in the course of building open, fully engaged networked environments, also create transformative relationships with their clients.Join our efforts to promote online network literacy Become a member of our community of practice or liking our Facebook page.

Womens basketball coach Patrick Kleins career continuing to soar since unconventional beginning

Patrick Klein calls out a play from the sideline during an OSU basketball game. Credit: Courtesy of OSU AthleticsPatrick Klein didn’t quite get the introduction to basketball that he expected. He wished to become a walk-on player as an Ohio State student, but things changed quickly.“I left my dorm and my friends were wishing me luck,” Klein said. “I came back and said ‘Hey, I made it, but the women’s practice team.’”Even though the position was not what he had originally envisioned, Klein rolled with the punches and quickly began working his way up the ranks of women’s college basketball, recently leading to a promotion to associate head coach of the OSU women’s basketball team.By the time he graduated from OSU in 2005 with a bachelor’s degree in business management, Klein — a native of Belpre, Ohio — served as a student manager for the women’s basketball team from 2004-2005.Upon earning his undergraduate degree, Klein stayed at OSU as a graduate assistant under former head coach Jim Foster from 2005-2007.Klein then moved on to the University of Illinois, where he was an assistant coach from 2008 to 2010. For the 2011-2012 season, he returned to OSU, where he spent the next five seasons as an assistant coach.“For them to make that job title for me, it was an honor,” Klein said.Although he is appreciative of the promotion, Klein has never been caught up with labels.“When you work with great people, it’s not about the titles,” Klein said. “It’s just about every day working together for that common goal.”Despite the new title, Klein’s duties for the team remain the same. He will continue to be a key contributor in the recruiting process, provide detailed analysis on OSU and its opponents and will continue to push his agenda of proving OSU has a top women’s college basketball program“One of the big things for us here is being the best, the absolute best at developing young people,” Klein said. “In order to be the best, you have to really have the opportunity to focus on the details every single day.”Coach Kevin McGuff has had Klein as an assistant coach in his first three years at OSU.“He’s done a great job since he’s been here,” McGuff said. “He’s really helped us develop the program.”Off the court, Klein has helped bring in several highly rated recruiting classes for the Buckeyes.“Really, he’s been impactful on all of the recruits that we have gotten here,” McGuff said. “He’s very much a people person and he’s got great organization skills.”Klein also helped aid the club’s scoring spike in the 2015-2016 season, when OSU scored 86 points per game to set a new school record.“I think it’s just trying to execute coach McGuff’s vision, it’s trying to play really fast and aggressive,” Klein said. “We have great players out there that play hard and create an environment where both defense and offense creates points.”Looking ahead to the upcoming campaign, Klein said he is excited to see this year’s group take the floor.“Not only from a talent standpoint, but just the chemistry and how our team has grown together. I think that makes us really special,” Klein said. “When we’re playing the schedule that we’re playing — South Carolina, Miami, UConn — these are teams that you have to be totally focused and you have to continue to be prepared. Everybody’s role is going to be important this year.”As for his coaching future, Klein isn’t in any rush to move on from his current role with the Buckeyes.“Any time that you can coach at your alma mater, it’s a really special thing.” Klein said. “I have one of the best jobs in women’s college basketball.” read more
