Comparison of two time-variant forced eddy-permitting global ocean circulation models with hydrography of the Scotia Sea

first_imgA comparison between hydrographic observations and output from two realistically forced z-level global ocean circulation models (OCCAM and POCM_4C) in the Scotia Sea, South Atlantic, is described. The study region includes the southern part of the Antarctic Circumpolar Current (ACC) and the northern Weddell Gyre. Despite similar formulations, the models have different strengths and weaknesses. OCCAM simulates well the horizontal circulation around South Georgia but loss of Antarctic Bottom Water distorts the mean circulation in the central Scotia Sea. A poorer bathymetric dataset in POCM_4C means that the circulation is not adequately topographically steered leading to greater zonal flow and a southward shift of the fronts of the southern ACC. In a comparison with sea surface height variability data, OCCAM overestimates and POCM_4C underestimates the maximum values. Both models have higher background variability than the satellite data. Mean monthly model output is compared with a meridional hydrographic section from the study region. The regional water masses at the time of the hydrographic section (April 1995) are recognisably reproduced in both models despite some discrepancies. The surface waters are too saline in OCCAM (by 0.12–0.40) and too warm in POCM_4C (by>2 °C) suggesting problems with the air-sea surface heat and freshwater fluxes used to force both models and the models’ vertical mixing parameterisations. Anomalous mixed layer properties in winter lead to inaccurate Winter Water characteristics in both models. Slumping of Circumpolar Deep Water occurs in OCCAM, associated with the loss of the bottom water. Subsurface restoration to climatology at buffer zones prevents this slumping in POCM_4C although the densest waters are not reproduced. The models overestimate the baroclinic transport of the section by up to a factor of two and simulate a significant barotropic component of transport. Overall, both models can be used in this region in ways that utilise their strengths. Further improvements are likely to come from better bathymetric representations, surface fluxes, and bottom water formation processes, elimination of spurious diapycnal mixing, improvement of vertical mixing parameterisations, and higher resolution.last_img read more

Government stalemate hinders aid to Haiti

first_img Tweet NewsRegional Government stalemate hinders aid to Haiti by: – July 29, 2011 Share Share Sharecenter_img 14 Views   no discussions Clearing and reconstruction work in Port-au-Prince, Haiti (UN Photo)PORT AU PRINCE, Haiti — A United Nations advisory group on Haiti on Thursday reported improvements in the earthquake-torn country but said aid coordination remains a challenge, and a stalemate in the formation of the government is delaying aid.The Economic and Social Council’s (ECOSOC) Ad Hoc Advisory Group on Haiti, reporting on the results of a four-day visit to the Caribbean nation in June, said: “The first finding of the group is that the situation on the ground has improved since its visit at the same time in the previous year.”“The progress made in clearing and reconstruction work in Port-au-Prince and neighbouring towns is visible and shows that Haitian society is mobilized and that the aid provided by the international community has been useful,” said the 13-member group.The group cited accomplishments in recovery from the devastating earthquake of 12 January 2010, which resulted in more than 220,000 deaths and delivered a severe blow to country’s already shaky infrastructure. It singled out successes in debris removal, resettlement of displaced persons, and the fight against cholera.However, the group’s 19-page report added that “aid coordination is a major challenge on which the group has been focusing for several years.”“It has become particularly urgent in view of the greater number of development partners providing aid to Haiti and the resources committed to the reconstruction process,” it said. “Almost all of the interlocutors of the group held the view that aid is still not sufficiently coordinated, which creates duplication and reduces the effectiveness of interventions.”Nigel Fisher, the deputy special representative of the secretary-general in Haiti, told ECOSOC that the implementation of the government’s priorities was “significantly delayed” because of an ongoing stalemate in a struggle between President Michel Martelly and Parliament over the confirmation of a new prime minister.Ambassador Keith Morrill of Canada, which led the group, said “the inability of political actors to find a rapid solution to this stalemate is having detrimental consequences on international assistance, on Haiti’s prospects for development, and most importantly, on its people.”The advisory group recommended a continued, strong UN presence on the ground but also suggested the international body should “pool the resources of United Nations entities on the ground, including in the provinces, and encourage all development partners to increase their share of the number of staff posted outside of Port-au-Prince, thereby increasing local capacities and supporting decentralization efforts.”They also recommended that the Haitian government improve agriculture productivity, create jobs through government, business and union cooperation, and integrate disaster preparedness into its capacity-building.Caribbean News Now Sharing is caring!last_img read more

Local, migrant women share stories

first_img24 August 2011 In an attempt to build bridges between local and foreign women, the City of Johannesburg and the Department of Home Affairs recently held a women’s dialogue where issues of xenophobia and language difficulties were tackled. Held at Diepkloof Welfare Centre on 19 August, the theme of the dialogue was “Working together to enhance women’s opportunities to economic empowerment”. It was open to local women and foreign migrants living in Joburg. From Joburg, the member of the mayoral committee for health and human development, Nonceba Molwele, was there to spend the day with migrant women from various countries, such as Democratic Republic of Congo, Nigeria, Ethiopia, Angola and Somalia.Breaking down barriers According to Molwele, the dialogue was held to seek to break down the barriers that kept migrant and local women from connecting. These barriers were language difficulties, xenophobic community attitudes, fears about immigration or residency status, and physical and cultural isolation. She said the dialogue was the first of its nature. “It is indeed a great initiative by our deputy minister that should not stop here but should be a start to an ongoing plan that will lead to concrete a joint programme that addresses the challenges of women as a whole.” August was chosen for the dialogue as the month was dedicated to honouring and celebrating the courage, tenacity, resilience and victory over adversity of women in South Africa, she explained. “Migration has always been a human rights issue throughout human existence, and Joburg has been a destination point for migrant communities since 1886. “In recognition of the challenges that are brought by human motilities, the City of Joburg has over the past 10 years been actively engaged in the pursuit of finding creative and sustainable responses to this phenomenon,” said Molwele.Sharing experiences as women Issues raised by migrant women at the dialogue included being mistreated at health institutions and being called nasty names by South Africans in public transport because of language barriers. Women, who came dressed in their traditional clothes, showcased traditional dances and explained their cultures to each other. The deputy minister of home affairs, Fatima Chohan, who spent the day listening to the women’s queries, urged them to unite despite racial, ethnic and cultural differences. “We are here to share our experiences as women and by coming together we can come up with the solution to what is bothering us as women,” she said. “If women can join hands, exchange ideas, then we will have a community that is at peace with itself.” By joining hands, women could achieve much more. “We want to create this opportunity for women from different parts of our continent to talk to each other so they develop friendships,” she added. Rebecca Khamba, who comes from Congo, was one of about 300 women at the meeting. She said the programme was a good initiative. “I would like to thank the City of Joburg for giving us a chance to join hands and create unity with our South African sisters. I hope most South Africans will understand why we are here and stop calling us names and mistreating us in public places,” she said. Source: City of Johannesburglast_img read more

Is a Tech-Based Social Credit Score a Good Idea?

first_imgFrank is a freelance journalist who has worked in various editorial capacities for over 10 years. He covers trends in technology as they relate to business. Frank Landman Why IoT Apps are Eating Device Interfaces Follow the Puck What it Takes to Build a Highly Secure FinTech …center_img Related Posts China is currently developing a kind of social credit system, not dissimilar to a financial credit system, designed to reward people for doing good deeds and demonstrating honesty and integrity while punishing people for committing untrustworthy acts. The details of this system are still fuzzy; it’s not certain whether it will be a compilation of big data from multiple sources or whether it will be one centralized platform. However, it’s certainly going to rely on big data and high-tech analysis to make evaluations.On the surface, this kind of system sounds like something out of Black Mirror­—a nightmarish evaluative hierarchy that would needlessly segment people into classes and exclude them from living a normal life. But are there merits to such a system, and should we consider implementing one?Comparisons to Financial CreditIn a sense, we already have a similar credit-based system in place: financial credit, with the FICO score being the main type of credit score considered. Many of the criticisms of a social credit system could also be applied to our current financial credit system, yet we still rely on it for the majority of our loan decisions and have become comfortable with it.For example, as you’ll see, one of the biggest criticisms for this type of system is the type of limitation it would impose on people with a low credit score. However, there are currently and would always be options for people with low credit; it’s entirely possible to get a credit card if you have bad credit, and it would be entirely possible to build a family and lead a normal life if you have bad social credit.Similarly, both systems allow you to improve your score over time. Rather than being permanently blacklisted based on one action or mistake, your score is fluid, and will automatically adjust if and when your behavior is corrected.InfractionsOne major point of contention is deciding which infractions, behaviors, or habits would be most likely to impact your social credit score. Some obvious infractions would be met with near-universal agreement. For example, when someone commits a premeditated, violent crime, it should be reflected on their social credit score. This isn’t much different than recording and reporting standards for felonies as they exist today. Lesser crimes, like jaywalking or littering, would come with a marginally less serious penalty on your social credit score.The real controversy comes into play when you consider relatively innocent infractions. For example, in China, failing to visit an elderly parent or putting out the wrong items with your recycling could result in damage to your social credit.PunishmentsThe punishments also need to be considered. If the consequences of a low social credit score are minimal, few people would object to the system. But if they’re too lax or are not incentivizing, the system would be practically useless.Currently, the system will impose restrictions on travel if your social credit falls below a certain mark. You may also have trouble getting your children into private schools, which is much more impactful. Your credit score may also influence your social status; for example, some dating apps in China will publish your social credit score, which could influence how you pursue romantic interests. It could even spur bias in hiring decisions, preventing people from getting a job they might otherwise be qualified for.Deciding on a SystemThe biggest issue isn’t with the nature of a social credit system, since most of us act as if there’s an informal one in place already. Instead, it’s with how the system is created and implemented.For starters, will this system be centralized, with one set of standards for determining how a credit score is calculated and how punishments or rewards are doled out? Or will there be multiple sources of information coming together as one? Either way, who will be making this decision, and how will that decision be implemented?There are several problems to work out here:Which infractions count, and how are they reported? The first question most people have is which social infractions or good deeds are going to count, and how are those infractions going to be reported? For crimes, this is straightforward; in addition to creating a writeup or making an arrest, a law enforcement officer could easily submit a report to the central social credit agency or each of several minor social credit agencies. It would take a lot of time, but would be somewhat clear-cut. Lesser infractions would be a bigger issue, since they would often rely on peer reporting. Peers aren’t typically reliable witnesses, so it wouldn’t take long for the system to be entirely compromised.How will discrepancies be resolved? There are multiple discrepancies that could potentially arise. For example, if there’s only one database, what happens if someone sees an infraction reported that they’ve never committed? Or what happens if a single infraction is reported multiple times? More importantly, what happens if you’re using multiple social credit reporting systems, and two of them conflict with one another? A blockchain-like system of verification could help here, but it wouldn’t solve everything.Who can “see” or request social credit? Your credit score can only be accessed by certain individuals and organizations, so would your social credit score be similarly protected? For example, would an employer be able to find your social credit score if they were considering hiring you? What about a vindictive neighbor who’s trying to find a reason to have you evicted?Who’s creating the analytic system? Bias is prevalent in almost any algorithm. No matter how “smart” your AI is, if it’s been created by humans, it’s going to have flaws. There would need to be a series of checks and balances to make sure the system being created is as fair and unbiased as possible.Can social credit be appealed? What can you do to improve or appeal your social credit? Is there a statute of limitations for when and how infractions can be reported? Do infractions expire after a certain amount of time?The Potential BenefitsObviously, a social credit system would be incredibly complicated to develop and roll out, so it would need to have some massive benefits if it’s going to be considered.There are some potential benefits—most notably, the incentive for people to avoid committing crimes and favor doing good deeds. A society where people have a strong reason to engage in honest business practices, or be positive contributors to their environments, is a society that functions harmoniously.There are also side benefits to consider for companies and organizations; companies would hypothetically be able to hire more trustworthy people, resulting in more efficient operations and better economic growth, and even advertisers could get in on the action, targeting ads to people with high or low social credit, or offering services for rebuilding a social credit score that has fallen to dangerously low levels.Are the Benefits Enough?Those benefits aren’t free, however. To get them, we’ll need to consider the right infractions to track, the right methods for processing the data, the right system or combination of systems to record everything, and enough checks and balances to ensure the overall system is as unbiased as possible. Such an undertaking would be ridiculously expensive and require lots of tech talent. It would also likely go through several iterations before we settle on a final setup—iterations which would be problematic for many citizens.Overall, a social credit system is fine in theory. It has a ton of perks and doesn’t necessarily predict a dystopia. The problem is, there are too many variables to consider for something as subjective as a person’s social trustworthiness, and unless we’re confident in our assessments, we shouldn’t be condemning people to any lifestyle or freedom-based punishment.
