Seasonality of reactive nitrogen oxides (NOy) at Neumayer Station, Antarctica

first_imgNO, NOy (total reactive nitrogen oxides), gaseous HNO3, and particulate nitrate (p-NO3−) were measured at Neumayer Station from February 1999 to January 2000. In addition, during February 1999, the NOy component species peroxyacetyl nitrate (PAN) and methyl, ethyl, i-propyl, and n-propyl nitrates were determined. We found a mean NOy mixing ratio of 46 ± 29 pptv, with significantly higher values between February and end of May (58 ± 35 pptv). Between February and November, the (HNO3 + p-NO3−)/NOy ratio was extremely low (around 0.22) and in contrast to NOy the seasonality of p-NO3− and HNO3 showed a distinct maximum in November and December, leading to a (HNO3 + p-NO3−)/NOy ratio of 0.66. Trajectory analyses and radioisotope measurements (7Be, 10Be, 210Pb, and 222Rn) indicated that the upper troposphere or stratosphere was the main source region of the observed NOy with a negligible contribution of ground-level sources at northward continents. Frequent maxima of NOy mixing ratios up to 100 pptv are generally associated with air mass transport from the free troposphere of continental Antarctica, while air masses with the lowest NOy mixing ratios were typically advected from the marine boundary layer.last_img read more

Picturing Harvard’s past

first_imgHarvard’s first class portraits are striking: 85 vivid daguerreotypes set into a handsome, custom-made chest of wooden drawers. The silver-coated copper plates were the work of pioneer Boston photographer John Adams Whipple, who made daguerreotypes in their heyday, the two decades following 1839. “The daguerreotype process yielded images that were exquisitely detailed and luminous,” said exhibit co-organizer Melissa Banta, a projects curator at Harvard.The Class of 1852 daguerreotypes were given to the University Archives, which were then just a year old. This collection of class photographic portraits was the first predominantly visual artifact of its kind, said University archivist Megan Sniffin-Marinoff. “Students at the time were using new technologies, just like they are now, to capture memories.” Before the breakthrough Class of 1852 daguerreotypes, she added, “memories for students were written” in letters and diaries.To get their pictures taken, the Class of 1852 seniors — whisker-proud and togged out in waistcoats, starched collars, and ties — reported to Whipple’s sky-lit studio on Washington Street in Boston. Among them was Horatio Alger Jr., reputed to be the smallest member of the class, and later the wildly successful author of the “Ragged Dick” series and other juvenile literature.Whipple used a technique he called “crayon portraiture” to give his daguerreotypes a soft, diffused quality. He also produced the first daguerreotypes of the moon, taken through the telescope at the Harvard College Observatory. From 1856 to 1859, when Harvard class albums were evolving fast in size and character, Whipple was a partner with James Wallace Black, whose pictures of Boston, shot from a hot air balloon in 1860, were America’s first successful aerial views. They showed “Boston, as the eagle and wild goose see it,” wrote Harvard Professor of Medicine Oliver Wendell Holmes.Daguerreotypes, one-of-a-kind images, were taken for the Class of 1852. Salt-print copies were made so students could have pictures of their classmates. (Salt prints, introduced by photography pioneer William Henry Fox Talbot in the 1830s, represented the first negative-to-positive photographic technique.) To sharpen the appearance of the copied images, Whipple devised the “crystalotype” by coating his glass negatives with a thin layer of an emulsion of albumin (from hens’ eggs) and honey.From 1853 to 1864, Whipple created salted paper prints from glass-plate negatives taken of the students for the Harvard portraits. He and others in that era continued experimenting with other coatings, including gelatin, gum arabic, wax, casein, and shellac. Starting in 1865, albumin prints (prints coated with albumin emulsion before they were developed) became the dominant technology.Students could now gather prints together in what would become the first photographic class albums. Making so many salt prints for image-hungry college seniors required a photographic assembly line. Negatives were clamped into large wooden frames, placed against paper coated with light-sensitive silver salts, and exposed to sunlight on the studio’s rooftop. Holmes, who dabbled in photography, marveled at the scale of the Whipple & Black enterprise.Compared with common black-and-white photographs from the 20th century, salt prints are more sensitive to light and, to some degree, more subject to fading. “We worked very hard to meet the best environmental conditions in the newly renovated cases for this exhibition,” said Weissman photograph conservator Elena Bulat, who organized the exhibit with Banta. “We have very low levels of light, relative humidity, and temperature in the cases. We also limited the time for displaying the objects.”The exhibit is part of the Salt Print Initiative being undertaken by the Weissman. It’s a University-wide initiative to identify, conserve, study, and enhance access to the thousands of salt prints in Harvard’s archives, libraries, and museums. Programs include workshops on the history and identification of the medium, condition surveys, guidelines for housing and storage, conservation treatment, material analyses, cataloging and digitization of selected collections, exhibitions, website development, and a symposium.These programs, as well as recent advances in material analyses, are helping to uncover a wealth of data about Harvard’s early paper photographs. The initiative, for example, is studying nine of the era’s predominant coatings, and has built a reference library to identify the coatings used in Harvard class albums. “We had great success,” said Bulat. “So far we were able to identify gum arabic, dextrin, and sandarac coatings.”Knowing which coating was used helps conservators as well as collection managers make appropriate treatment decisions, can aid in devising preservation recommendations, and — along with other information about the object — can help with attribution.Part of the Salt Initiative involves a new methodology to identify coatings with the help of Harvard’s Center for Nanoscale Systems. FTIR (Fourier Transform Infrared) in reflection mode does not require contact with a fragile print.Harvard seniors assembled salt-print images in small, personalized notebooks — the eclectic assemblages of images and text that prefigured the class albums we see today. The exhibit features the notebook album of Samuel Fisher Haven, Class of 1852. It’s the size of a small paperback.In later years, during reunions or other events, classmates continued to contribute to the official class album by adding pictures of their older selves, newspaper clippings, obituaries, and notes on occupations and war records. In addition to revisiting the official class albums, graduates could order their own custom-made albums.By 1861, Harvard class pictures were the work of George Kendall Warren, a Boston celebrity photographer who did college album work for Yale, Brown, Princeton, and other colleges. Harvard seniors assembling their own books requested prints from an order form of 100 or more images.Among them were views of college buildings, elm-treed Harvard Yard, and prominent faculty, including Holmes. A circa-1860 Warren portrait of Aaron Molyneaux Hewlett, on view in the exhibit, was available on the order form. Hired in 1859, he was director of the Harvard Gymnasium and the University’s first black staff member.Warren’s order sheets also included images of Dane and Gore halls, Holden Chapel, Stoughton and Hollis dormitories, and the Washington Elm.Images of landscapes, a Warren specialty, were offered too. Most popular were the photographer’s romantic renderings of Mount Auburn Cemetery, the nation’s first landscaped rural burial ground. Though it was a mile and a half from Harvard Square, the cemetery’s wooded rolling acres were considered a geographical adjunct of Harvard.By 1861, seniors could also order up more quotidian images, including those of “goodies,” female dorm room housekeepers, and of colorful off-campus personalities. The exhibit includes a portrait of Niccoline, the “candy boy” of Harvard Square.By 1864, the class albums that students customized for themselves had grown to embossed tomes 3 inches thick that could weigh 20 pounds or more. “The size and elegant production of the albums reflects the growing prestige of Harvard itself as it was transitioning from a college into a major university,” said Banta.By 1890, she added, the era of “more intimate, customized” albums came to an end. Replacing them were printed volumes of uniform design and content — the first yearbooks of the modern era.“We take yearbooks and class books for granted,” said Sniffin-Marinoff, who praised the exhibit for bringing together within one theme the worlds of photo curation and photo conservation. “We never think of the history.” Later this month, graduating Harvard seniors will get a class album memorializing their years of study and play. It will have hard covers, contain 500 pages on glossy stock, and weigh about 4 pounds — 16 ounces of memories per year.An exhibit at Pusey Library demonstrates how the first Harvard class photograph albums evolved. In the antebellum 19th century, photography was young, image technologies were changing fast (often with Boston practitioners in the lead), and Harvard students began adding the visual to the repositories of memory that for centuries had been dominated by text.“We Carry With Us Precious Memorials,” on view through June 29, begins with Harvard’s Class of 1852. Its 85 seniors — who appear to be “breezy, jovial characters,” the curators note — were the first to have their pictures taken for a collective photographic memento.The exhibit was a partnership of two Harvard Library departments, the Weissman Preservation Center and the Harvard University Archives.

Operation Hard Hat issues more construction zone tickets in 2020 than 2019

first_img“Anything that could potentially be reckless. That one mistake could be something that’s critical, it might critically hurt somebody or injure somebody, or even worse, kill somebody,” Said NYSP Troop C Public Information Officer Aga Dembinska. “We don’t want that to happen and we don’t want a motorist to have to live with that for the rest of their life.” The New York State Department of Transportation says often, road workers are working with their backs to oncoming traffic. This could create a dangerous situation if drivers aren’t paying attention or slowing down. “The safety of you, your family, and essential workers isn’t enough incentive, maybe a couple hundred dollars for a ticket might be,” said NYSDOT Region 9 Public Information Officer Scott Cook. (WBNG) — Operation Hard Hat has been running for several months, placing New York State Police troopers in construction zones dressed as road workers. center_img State troopers say they will continue to hold operations at active zones until construction season ends. In 2019, 1,048 tickets were issued in these zones, for anything from speeding, to using a cell phone. In 2020, that number has gone up to 1,222 tickets, and construction season isn’t over yet. last_img read more

We can’t do without people. We have to adjust to the weather. Focus on company culture

first_imgWithout people we can do nothing. We forgot to be good hosts, the chef adds Rudolf Stefan from the award-winning Šibenik restaurant Pelegrini, confirming theses about man as the key to success in tourism and stating the fact of the relatively poor state of Croatia on the world gastronomic map and the state of Croatian gastronomy in general. However, there are some changes, as evidenced by 5 Michelin-starred restaurants, and chef Stefan hopes that there will be more soon. The PromoForum also asked questions about how to achieve greater efficiency and employee engagement, boost productivity and reduce stress levels, for which Bernard Šutić cited gamification as part of the solution. According to him, people simply like to play, they like competitions, they like to be ranked and they like prizes. It is easier to encourage people to engage by participating in a team, because unlike the actions of an individual, in a team people feel responsible for others and therefore invest more effort and greater engagement. And if we add ranking, scoring and rewards to that, there is no end to success, Bernard points out. These are just some of the conclusions of the conference PromoForum – a conference on human resources in tourism, which was held as part of the 35th edition of Promohotel, the international fair of food drinks and equipment for tourism. At the end of the lecture, the focus was on personal development, and his review was given by dr. Kenan Crnkić, a bestseller author, lecturer and high performance coach who stressed that we need to think carefully about our time, how we use it and to whom we give it. Be careful what you listen to and watch, who you hang out with, who you seek advice from. Without people we can do nothing. We forgot to be good hosts. “This is an event that opened a very important topic for our tourism and thus made a step forward because it is a conference that put in absolute focus the topics, challenges and solutions needed for the development of the human side of tourism, without just part of a panel or one lecture within the program that deals with topics in tourism “, points out Marinela Dropulić Ružić, owner of the Meraklis brand, which deals with the sustainable development of human resources. People must want to change and adapt to the times, he says Dalibor Šumiga, behavioral marketing specialist. He also refutes the myth of bad bosses, who according to a survey in Europe have only 13%, adding that we cannot all be managers; if we are all to be managers, who will work? Will robots and millennials cross us? For now, we need not fear, but that the world is going in that direction, there is no doubt. “The average person nowadays gets more information in one day than he received in a lifetime in the 16th century. The digital age, as the latest industrial revolution, has brought great changes, and if we remain trapped in time, we become dinosaurs”Emphasizes Shumiga. It was Dropulić Ružić who opened the conference with an introductory lecture at which she presented the innovative NeuroHR, a methodology that measures subconscious reactions through neurotesting, ie by measuring brain impulses in real time. People need to want to change and adapt to the times. center_img In these endeavors, we return again to the people, especially the young. In his own example, these are big and commendable steps: continuous education, support and encouragement of young people and most importantly, adaptation to their wishes and needs. “Because if we want to keep young people, we have to adapt to them. And in the overall process of change that will inevitably have to start happening, the key role will be played by the guests, those of whom and for whom the caterers work, and we will all have to invest a lot of will to make us all happy in the future.”Emphasizes Štefan. Monika Ivanović, the head of the employer image management team at Infobip emphasized that with the dynamics of 7 billion messages per month, it is crucial to have a good platform, but also good people. And in order to get and keep good people, you need to invest work and effort that, proven and guaranteed, always pays off in the end. Employee satisfaction is their number one priority and this is achieved through various activities and factors, and Ivanović notes the importance of a quality and focused onboarding process that aims to make employees feel at home, because the salary motivates people to some level; the culture of the company also plays an important role. Salary motivates people to some level, but the culture of the company also plays an important role. Dragan Vojvodić, licensed Sandler coach from Serbia completely knocked the audience off its feet with its unconventional perspective and numerous concrete examples that touch on ways to sell yourself and your object in a completely different way, outside the framework of known and completely outdated patterns. Salary motivates people to some level; the culture of the company also plays an important role The conference on human resources in tourism was closed by Ivana Štiković, director of Promohotel and PromoForum: “PromoForum is the first conference that put in absolute focus the topics of personal and professional development of human resources in tourism and we are very proud of this step and we thank all those present who recognized this initiative” Photo: Facebook Promohotel 2020last_img read more

Wasswa, M. Juuko, K. Aucho, G. Kizito , T, Mawejje, F Miya, G.Massa (Capt), J. Ochaya.Port-Gentil, Gabon | AFP | Ghana secured their place in the quarter-finals of the Africa Cup of Nations as Asamoah Gyan’s goal was enough for them to beat Mali 1-0 in Port-Gentil on Saturday.On an appalling playing surface, Gyan headed home from Jordan Ayew’s cross in the 21st minute to score his eighth goal at the Cup of Nations over six consecutive tournaments going back to 2008.With two wins from two matches in Group D, 2015 runners-up the Black Stars are certain of another appearance in the knockout stage of a tournament they have won four times.Mali have just one point but are not out of it yet, while Egypt and Uganda meet in the other Group D game later.The state of the pitch meant the teams were not allowed to use it for their pre-game warm-ups, instead being forced to do use an indoor facility.The surface did not lend itself to a flowing game of football, but at least the sizeable Malian community in this Gabonese port city made for a raucous atmosphere.Sadly for them, Ghana initially coped better on the pitch and they should have been in front in the 17th minute.The standout performer at the last Cup of Nations, Christian Atsu did brilliantly on the right before delivering a low ball to the near post which Jordan Ayew would surely have converted.However, Andre Ayew took the ball off the feet of his younger brother and stabbed a shot wide.Nevertheless, Avram Grant’s men were ahead before the midway point in the first period as Jordan Ayew crossed from the right and captain Gyan rose unmarked to head past Oumar Sissoko in the Mali goal.The Ghana players celebrated by running across to the bench and holding up t-shirts with a message of support for left-back Abdul Rahman Baba, whose tournament was ended by a serious knee injury in the opening win against Uganda.Sissoko did well to save a Jordan Ayew cross-cum-shot that bounced awkwardly in front of him and Mali then came out with greater purpose after the break.Just as in their opening goalless draw with Egypt, the introduction of exciting young Lille midfielder Yves Bissouma gave them an extra impetus.Despite that, they could not find an equalising goal, with Moussa Marega heading straight at Razak Brimah from a Bakary Sako cross and defender Salif Coulibaly hooking a shot just wide after Ghana had struggled to clear their lines.Ghana were hanging on right until the end, with goalkeeper Razak making a fine reaction save to deny substitute Kalifa Coulibaly from point-blank range in the 90th minute and then beating away a Sako volley in injury time.Cranes face uphill taskWasswa in action in the game against Ghana.Cranes can look back at their second half performance against Ghana as an indication they can match the very best at the African Cup of Nations.They will need that level of performance, and more, when they face record seven-time champions Egypt today. Uganda’s record against the Pharaohs shows only one previous win – in a friendly.“We need to be mentally strong, physically fit and tactically competitive in that game and see what football gives us,” admitted coach Milutin ‘Micho’ Sredojevic. 27 Dec 2005Egypt v UgandaL2-0LG Cup Uganda played well for much of their opening match against Ghana but Micho was left to lament a mistake by defender Isaac Isinde that gave the Black Stars the decisive penalty.The Cranes are now looking for their first win at the Cup of Nations after 39 years away from the tournament and they can welcome back defender Murushid Juuko and midfielder Khalid Aucho after both served bans against Ghana.“It is very unfortunate that one moment, one silly mistake cost us the penalty,” Uganda coach “Micho” told AFP.“It is very unfortunate that despite all the domination we had in the second half, we could not score.“But we have picked up the pieces, we have learnt the lesson and we are moving forward to the next game.Defeat today will mean certain group-stage elimination in their first appearance at the tournament in 39 years. 08 Jan 2011Egypt v UgandaL1-0International Friendly Africa Cup of Nations 18 Nov 1977Egypt v UgandaL1-0International Friendly 08 Jan 2005Egypt v UgandaL3-0International Friendlycenter_img 17 Jan 2011Egypt v UgandaL3-1International Friendly 01 Mar 1974Egypt v UgandaL2-1Africa Cup of Nations 29 Mar 2012Egypt v UgandaL2-1International Friendly 21 Jan 1995Uganda v EgyptD0-0Africa Cup of Nations 20 Aug 2002Egypt v UgandaL2-0International Friendly 03 Dec 1972Egypt v UgandaD2-2International Friendly DateMatchResultScoreCompetition 21 Jan 2017Egypt v Uganda 14 Aug 2013Egypt v UgandaL3-0International Friendly Egypt goalkeeping crisisEgypt disappointed in their first appearance at the Cup of Nations after a seven-year absence, with star man Mohamed Salah being substituted in the second half following a poor display.Egypt enter the game with goalkeeping worries following injury to their first choice in the draw with Mali.Injury has also affected the other team in the group Ghana, with coach Avram Grant has called for Africa Cup of Nations organisers to allow teams to replace players who have suffered injuries because of the state of the pitches in Gabon.The Black Stars have lost left-back Abdul Rahman Baba to a serious knee injury suffered in the first half of Ghana’s 1-0 win against Uganda on Tuesday.Egypt also lost goalkeeper Ahmed El Shennawy to injury, and with Sherif Ekramy also in the treatment room suddenly coach Hector Cuper has a bit of a crisis.Essam El Hadary, who came off the bench against Mali to become the oldest player ever at the tournament at the age of 44, will now start against Uganda in Saturday’s second game.“Our responsibility has not changed too much. We still know that we need to win our next game to stay in the competition,” admitted Cuper.Ghana’s forward Andre Ayew celebrates after scoring a goal during the 2017 Africa Cup of Nations group D football match between Ghana and Uganda in Port-Gentil on January 17, 2017. Five facts for the Group D match between Egypt and Uganda in Port-Gentil Saturday :— Tradition suggests Egypt will win 2-1 because that was the scoreline in their favour on the three previous occasions they met Uganda in the competition.— The Pharaohs overcame the Cranes in a 1962 semi-final and during the group phase of the 1974 and 1976 tournaments.— While Egypt have won the Cup of Nations a record seven times, Uganda came closest to glory in 1978 when finishing runners-up to hosts Ghana.— Both countries have been notable absentees from the tournament with Egypt missing the last three editions while Uganda are appearing following a 39-year break.— Striker Mohamed Salah is the best known Egyptian while Ugandan goalkeeper Denis Onyango won the 2016 Africa-based Footballer of the Year award.Share on: WhatsApplast_img read more

Horswill, Currie lead Leafs to 5-2 win over Grand Forks

first_imgBy The Nelson Daily Sports Linden Horswill made his return to the NDCC Arena a memorable one as the Okanagan Hockey Association recruit scored his first goal as a junior sparking the Nelson Leafs to a 5-2 victory over the Grand Forks Border Bruins (see more coverage on Sports Page) Saturday night.
The 16-year-old native of Nelson, called up to play with the Leafs after the team was hit with a rash of injuries, scored the opening goal of the contest before adding an assist on the final marker.Gavin Currie also had a pair of goals to lead Nelson.The Leafs opened the weekend with a 7-4 loss to Beaver Valley Friday in Fruitvale.Nelson, 11-11 on the season, built up a 4-0 lead after 40 minutes before the Bruins woke up.“I don’t think it was any more difficult that we thought,” said Leaf coach Chris Shaw. “ Grand Forks has put a pretty good team together now. They’ve acquired some pretty good players from Revelstoke and we knew they’re going to be pretty tough to play against.”Marcus Dahl and Dallon Stoddart also scored for Nelson.Darren Hogg appeared to be heading for his second shutout of the season before the Bruins scored two quick goals in the third to make it a game.Joey Cormano and Artsiom Kalashnikov replied for the Bruins.Nelson out shot Grand Forks 27-20.In Fruitvale, Dallas Calvin scored a natural hat trick to spark the Hawks to a 3-0 lead five minutes into the second period.Colton Malmsten cut the margin to 3-1 with a goal three minutes later.But Ryan Baines and Ryan Edwards scored power play markers to increase the Beaver Valley lead to 5-1.Riley Henderson scored on a Nelson power play to give the visitors some momentum entering the third.The Leafs struck for two goals three minutes into the final frame as Patrick Martens and Colton Schell, on the power play, cut the lead to 5-4.However, Justin Niminiken scored a power play goal to diffuse the Leafs.Nelson Minor Hockey grad Ryon Sookro added an empty net marker to round out the scoring.Beaver Valley finished three-for-five on the power play while Nelson was two for six.Mike Vlanich out dueled Marcus Beesley in the nets to register the win for Beaver Valley. Shots were even at 38-38.The win was the third in three games for the Hawks over Murdoch Division rival Nelson.LEAF NOTES: Nelson’s GM Chris Shaw announced following the game that Nelson acquired Joel Stewart in a trade from the Spokane Braves. In 16 games this season the 6’1”, 190-pound winger had eight goals for 16 points. . . . Nelson was missing leading goal scorer Connor McLaughlin, called up for a northern road trip with Trail of the B.C. Hockey League. McLaughlin scored twice in the third period to spark a four-goal explosion as Trail dumped Prince George 5-3 Friday. Trail, 17-7-0-1, leads the Interior Division by five points over Salmon Arm. McLaughlin, named the game’s second star, finished with three points. He did not play in Trail’s 2-1 loss to Quesnel [email protected]last_img read more

ACCEPTANCE EXTRA GAME IN WINNING $100,000 CALIFORNIA FLAG HANDICAP BY A HEAD UNDER ELLIOTT; TRAINED BY BLACK, VRONSKY COLT GETS 6 ½ FURLONGS DOWN HILLSIDE TURF IN 1:11.51

first_imgARCADIA, Calif. (Oct. 22, 2016)–Sent hard from the gate, trainer Kenny Black’s Acceptance proved extra game in deep stretch, as he held off a tenacious Richard’s Boy to win Saturday’s $100,000 California Flag Handicap under veteran Stewart Elliott. Bred in California by Old English Rancho, the 4-year-old colt by Vronsky got 6 ½ furlongs down Santa Anita’s hillside turf course in 1:11.51.Breaking from post position six in a field of seven California-bred or sired runners three and up, Acceptance out-dueled the runner-up going to the half mile point and was able to secure an inside position at the rail prior to crossing the dirt at the top of the lane. From there, he was all heart to the wire as he fended off serious challenges from both Richard’s Boy and favored Boozer, who ended up finishing fifth.“He was tough today,” said Black, himself a former top apprentice rider in the early 1980s. “I thought they had him two or three times, but he just dug in. You’ve got to be proud of him. He really showed a lot of heart today…I just told Stewart (with whom Black rode as a young tyro) to meet me in the Winner’s Circle…I don’t even want to think about what race might be next. I want to give him more time between races.”Owned by Finish Line Racing, LLC and the Ellwood Johnston Trust, Acceptance, who was off at 5-1, paid $12.20, $6.00 and $4.00. A two-time stakes winner on dirt as a juvenile, Acceptance garnered his fourth win from 11 overall starts. With the winner’s share of $60,000, he increased his earnings to $366,803.“He’s a nice horse,” said Elliott. He’s got ability and he tries. He’s pretty quick himself, but that was a good post…I rode him last time (a close fifth place allowance finish down the hill on Sept. 30). Kenny said he’d put me right up there or be very close and that was it.”Ridden by Victor Espinoza, Richard’s Boy held off late closer Somethings Unusual by a half length for the place. The narrow second choice in the wagering at 7-5, Richard’s Boy paid $3.20 and $2.60.Last after the first half mile, Somethings Unusual rallied wide-out under Drayden Van Dyke and finished third, 1 ¼ lengths in front of McHeat. Off at 15-1, “Something” paid $5.00 to show.Fractions on the race were 21.49, 43.19 and 1:05.47.last_img read more

Anti-corruption courses in African business schools could help end graft

first_imgEducation could be a valuable weapon in Africa’s fight against corruption. Three business schools – in Nigeria, Tanzania and South Africa – already offer anti-graft coursework, and the results are positive.A billboard in Namibia spread the message of the country’s Anti-Corruption Commission, or ACC. Anti-corruption education, the authors say, must become a priority in African classrooms. (Image: Philip Schuler, World Bank)Shiv Tripathi and Ganka Daniel Nyamsogoro, Mzumbe UniversityCorruption touches our lives every day. It happens across the private sector as well as the public service in the realms of housing, education, health and agriculture. Its influence reaches dangerously further, too: it directly threatens sustainable development.Corruption takes many forms. This makes it almost impossible to definitively calculate its cost, though one estimate suggests that corruption amounts to more than 5% of global GDP.Research by the World Bank shows that about US$1-trillion is paid in bribes worldwide each year. Africa is home to several of the most corrupt countries in the world, according to Transparency International’s Corruption perception index.Corruption also makes it difficult for societies and economies to develop. Sub-Saharan Africa is one of the poorest regions in the world and it, along with the rest of the globe, is now gearing up to meet the sustainable development goals. Most of these goals are sadly vulnerable to corruption, whether in the realm of poverty eradication, access to health care or affordable energy.Education could be a valuable weapon in the continent’s fight against corruption. Three business schools in Africa are already putting this theory to the test by introducing an anti-corruption programme, sanctioned by the United Nations, into their classrooms.We piloted and researched their experiences for our new book, which outlines how anti-corruption education can be professionalised in business schools around the globe.The business of fighting corruptionResearch tells us that corruption can hamper the ability of a business to run well and profitably. It can affect the entire business supply chain and ultimately lessen an enterprise’s contribution to broader social and economic development.One estimate suggests that about 80% of Africa’s job creation and its economic output depends on small and medium enterprises.These are just some of the reasons that we believe anti-corruption education belongs in business schools. If the continent can produce business leaders who are able to identify and act against different forms of corruption, it will make a huge difference to economic growth and the successful implementation of the sustainable development goals.There is no single correct approach to embedding anti-corruption issues in education, but a great deal can be learned from available frameworks. One of these is the UN-sanctioned Principles for Responsible Management Education Anti-Corruption Toolkit.The toolkit was developed by a group of nearly 40 management scholars from around the world. The project was funded by the Siemens Integrity Initiative and the first draft was launched in 2012. It has since been tested and refined at 14 business schools in India, Eastern Europe, Europe, South America and Africa.The toolkit is continuously updated. It offers case studies and research about corruption which can be introduced into a classroom for discussion. It also has a section dedicated to teaching methods, which helps to guide those lecturers who have never tackled this complex topic before.In Africa, the toolkit was piloted in three different schools, which each applied it to different courses. Nigeria’s Lagos Business School adopted its contents into the MBA programme curriculum. Stellenbosch University in South Africa tested it through an ethics course for managers. At Mzumbe University in Tanzania, it was used in regular postgraduate level courses and in executive education programmes.At Mzumbe, the toolkit was used to start discussions about how integrating East Africa could minimise corruption and how to deal with ethical dilemmas in cross-cultural settings. The toolkit also provided material for a 12-hour programme that taught established professionals about ethical compliance in procurement.Other pilot sites used the toolkit to link the impact of corruption to a particular business context. Students were encouraged to share their own experiences and to envision the adverse impacts their crooked business decisions might have on their own and others’ quality of life.Feedback from the students was very positive at all pilot business schools.Sharing the lessonsThe major challenge for anti-corruption education lies in its integration with existing curricula. Students enrol for higher education seeking knowledge and the skills they’ll need to follow a particular career path. They will respond best to being taught about anti-corruption measures if they know this will be useful in their working lives. If businesses want to minimise corruption, they must emphasise ethical values and skill sets when recruiting business schools graduates.Beating corruption will require a collective effort from more than just business schools and corporate leaders. But anti-corruption education has an important role to play in this fight. It must become a priority in African classrooms.Shiv Tripathi is professor of Business Management, and Ganka Daniel Nyamsogoro is associate professor and dean, at Mzumbe University.

This article is only available to GBA Prime Members During the winter, the air near your floor is cold, while the air near your ceiling is hot. Similarly, during the summer, the air conditioner keeps your first floor comfortable, while the rooms on the second floor are unbearably hot. What’s going on?The usual answer is, “Heat rises.” But that explanation isn’t quite accurate. (It’s true that hot air rises by convection. But heat travels in all directions, including sideways and downward, by conduction and radiation.)The scenarios I’ve described are variations on the theme of temperature stratification — problems caused when indoor air temperatures are layered horizontally, with cold air down low and hot air up high, like layers in a parfait.Let’s start with a simple example: a single-story slab-on-grade house with temperature stratification problems. The thermostat is 48 inches above the floor, and it’s set at 72°F. On a winter day, when you are sitting at your desk, the air near your feet is at 65°F. Up near the ceiling, the air is at 79°F. Why?There are two main causes of this phenomenon.Air leaks coupled with the stack effect. The most important factor in this type of stratification is air leakage. Holes near a home’s ceiling allow warm interior air to escape into the attic. As this air escapes, it pulls in cold exterior air through cracks near the floor — for example, cracks near the threshold of an exterior door. The engine for this type of air movement is the stack effect. Since the warm interior air near the ceiling is at a positive pressure with respect to the outdoors, it wants to escape. Since the cool interior air near the floor is at a negative pressure… center_img Start Free Trial Already a member? Log inlast_img read more
