Ready, Aim, Flower

first_imgHow does a plant know the time to flower?  A new study describes a process involving genes, sunlight sensors, switches, clocks, feedback loops and messages.The research, published in Science,1  focused on a protein that is sensitive to day length.  The longer the day, the more the protein is produced.  Its activity is controlled by the circadian clock, a set of genes and proteins that keep time in all plants and animals.  In the lab plant Arabidopsis, this protein, named FKF1, is allowed (when the days become long enough) to activate another protein that activates flowering.  This second protein, though, has to travel from the leaves where it is made to the tips of the stem.  There, it turns on the flowering system.The paper described the complexity of the system:The FKF1 photoperiod sensor uses multiple, partially redundant switches to allow strong activation in long days. As the Sun rises higher in the sky each day when spring approaches, plants can sense the increased intensity in the blue-light range of the spectrum each afternoon through multiple photoreceptors, including FKF1. The complexity of this mechanism even in a temperate species such as Arabidopsis suggests that it has the flexibility to regulate successful reproduction in a wide range of environments.In other words, their lab plant has probably one of the simpler systems.  Seasonal response is probably even more complex in some plants and animals, but even bacteria are known to have circadian clocks of Paley-like complexity.  Neither the paper nor the summary on PhysOrg mentioned evolution.1.

Final whistle for winning Team SA?

first_imgCape Town was the host city for theHomeless World Cup in 2006. Gerald Bez shoots for goal during theHomeless World Cup match between SAand Australia, held at the Grand Paradein Cape Town, South Africa, in 2006.(Images: Flickr)MEDIA CONTACTS• Clifford MartinusSAHSS: Director+27 21 704 6815 / +27 82 945 4812Ray MaotaThe South African Homeless Street Soccer (SAHSS) initiative teaches young people life skills for handling issues such as HIV/Aids, crime and substance abuse.This they do by using soccer as a tool to keep them off the streets and opening them up to opportunities outside their normal environment.The initiative is part of Oasis: “Reach for your dreams”, which was started in 2000 by director Clifford Martinus and his friends as an informal soccer team for youngsters living in the streets of Cape Town, but grew bigger and was formally registered as a non-profit organisation (NPO) in 2002. Oasis Soccer Club still exists today and takes part in local tournaments.Established in 2006, the SAHSS became part of a worldwide network known as the Homeless World Cup Foundation, which includes 94 international partner organisations whose goal is to improve the lives of homeless people through soccer.The foundation is the brainchild of Mel Young, the co-founder of The Big Issue, a weekly magazine sold by homeless people in Scotland. He is also responsible for setting up the International Network of Street Papers (INSP), a global network of street papers sold worldwide.It was in Cape Town, at the end of the annual INSP conference in 2001, that Young and Austrian Harald Schmied, who is also involved in issues relating to homeless people, came up with the concept of the Homeless World Cup Foundation.“When we started out it was just to get the youth busy with soccer,” said Martinus.“Never did we realise that this was the beginning of a way of reaching more people and become a sense of opportunity for others less fortunate than ourselves.”He added that they are looking to expand their soccer programmes to more provinces and in future host a national street soccer tournament.Team SA is ranked 20th out of 56 nations involved in the international tournament. This year’s event takes place in Mexico in October and will host a record 72 countries, with 56 taking part in the men’s event and 16 in the women’s.The tournament started in Graz, Austria in 2003, and has been to four continents.National teams send different members every year, so as to give as many of their incumbents exposure to travelling and learning about new cultures as possible.“People tend to think this is just a joyous trip, but for these youngsters, meeting people with similar situations – whether it is drug abuse of being considered anti-social – is an eye-opener,” said Martinus.“They are boarding a plane for the first time to another country, and when they get there they realise that some of the people they meet are going through the same situation and there is a way out of it.”Not only for the homelessMartinus said although it’s named homeless street soccer, it does not include only the homeless and destitute.“Most of the participants live in places of safety and are from the streets, while others live in informal settlements,” he said.The team taking part in this year’s event will consist of eight players, four technical staff members and two social workers. It is in need of funds to help cover travelling costs.Mobile phone company Cell C, which was team sponsor for the 2010 and 2011 competitions, has had to restructure its sponsorship responsibilities this year.“Unfortunately our funding this year has gone to women and children initiatives and we could not carry on with the sponsorship,” confirmed Mag Pillay, Cell C public relations manager.The issue is uppermost on Martinus’s mind.“We need to get funds for flight tickets, the kit and a stipend for the players so they can feel comfortable among their counterparts at the tournament.”The cost of the trip is likely to exceed R200 000 (US$24 000) due to the airfares.Success stories of the initiativeAyanda Nqkayi (35) is a former captain of the team. Before joining the initiative he used to sell dagga as a means of survival, but through the SAHSS programme has become involved with the Cape Town Young Men’s Christian Association (YMCA).Nqkayi participates in YMCA projects such as the After School Programme, where youngsters are motivated to develop their education, confidence, leadership, and social skills in a safe environment.Martinus said they also recently had the Western Cape Street Soccer finals and called on previous players to facilitate with the proceedings so they can earn some money.Thulisile Bolana (24) from Khayelitsha is also a member of the SAHSS team. He will be going to Germany in June to a leadership camp organised by the UN Sport for Development and Peace. He is one of only three from Africa who were invited to represent the projects to which they belong and share ideas with others from around the world.He will be representing Oasis and speaking on how youth from around the world use soccer and sports in general to develop themselves.Lukhanyo Mdokwa, who was captain of the team in 2010, was taken in as assistant coach for South Africa at last year’s event. While there he was asked by the director of Paris-based Saint-Germain soccer club, who is Brazilian, to assist with the Brazil homeless team.“Lukhanyo will this year go again as assistant coach if we do get the funds to go to Mexico, but he will not come back to South Africa as he will join the Brazilian team and work at an NGO in Brazil,” said Martinus.last_img read more

Why Will They Say No?

first_imgOne of the most important areas for you to explore with your prospective client is what will cause them to say “no” to working with you.You may not want to explore these areas. It’s uncomfortable for you, and it can make your prospect uncomfortable. You don’t want to explore the areas where you, your company, or your solution have some challenges as far as your prospect is concerned. Your prospective client may not want to tell you outright that they can’t, don’t want to, or won’t be able to say “yes.” They might not want to embarrass you.They have something they “must have.” You can’t meet that need. They mention it but don’t make a big deal out of it. You both move on and talk about the areas where you do fit.The problem for you as a salesperson is that those things that prevent your dream client from saying “yes” didn’t go away. They are going to carry those concerns into their internal meetings, where they discuss you and your solution. Your prospects are also likely to talk about the things they need that you can’t provide when they speak with your competitors.Problems don’t age well, and neither do unresolved concerns.The best thing you can do is uncover the areas that are going to cause your dream client to give you a “no,” and see what you can do to mitigate those issues. Mitigation isn’t easy. If you had what they wanted, you’d be winning the deal. But you sell prospective clients, and you sell your company, as long as what your prospect wants isn’t something that should have disqualified them in the first place.You may need your manager’s help. You may need your operations team’s help. You may even need your leadership’s help. If you are going to win, you are going to have to find a way to flip what gets you a “no” to something that gets you a “yes.” It may not be a perfect solution. It just needs to be a solution your dream client can agree to. Get the Free eBook! Want to master cold calling? Download my free eBook!

Managing midlife transitions

first_imgWe’re all familiar with the stereotype of the 50-year-old man who exchanges his car for a flashier model, or trades his wife in for a younger model, starts covering his baldness and wearing younger clothes or chucks in his job to go off and travel the world. Less dramatic but disruptive nonetheless, mid-lifers may resort to drinking more alcohol than before, feeling depressed and blaming themselves for their failures, or putting excess pressure (possibly psychologically damaging) on their children to excel in academics or areas such as sports and arts.Many of us spend our 40s and 50s, even after having found our place in the world, re-evaluating our lives, searching impatiently for undefined goals, driven by a deep sense of remorse for unachieved dreams or a desire to relive feelings of youthfulness. An earlier generation of psychologists attributed it to the feelings that many individuals approaching the middle age of their lives experience, faced with the sense of the passage of their youth and the nearness of their old age and impending death. The Germans have a word for it: Torschlusspanik: the fear of doors closing. Normal transitions during this period of life, such as the death of parents, the realisation of being stuck in an unsatisfying career, the onset of menopause or children leaving home often trigger off strong feelings of dissatisfaction, self-doubt and depression in some individuals.It is popularly called midlife crisis. As a result, they may experience a powerful desire to make significant changes in core aspects of their lives: career, marriage, romantic relationships, big-budget expenditures, or physical appearance.advertisementBut a midlife crisis is not inevitable and may be less common than once believed. A new study in the Proceedings of the National Academy of Sciences reported that older people in their mid-to-late 50s are generally happier, and experience less stress and worry than young adults in their 20s. Though the traditional view about ageing is that the functions of the body and brain inexorably decline. However, recent discoveries in neuroscience show that the ageing brain is more flexible and adaptable than we previously thought. Throughout life, our brains encode thoughts and memories by forming new connections among the nerve bodies (neurons).With age, the neurons themselves lose some processing speed, but with the acquired learning of a lifetime, they become ever more richly intertwined, reflecting deeper knowledge and better judgment. The brain also becomes less rigidly bifurcated. Functionally two separate structures, the right brain and the left brain, are linked by fibres called the corpus callosum; the left specialises in speech, language and logical reasoning, while the right handles more intuitive tasks, such as face recognition and the reading of emotional cues. Unlike young adults, who handle most tasks on one side of the brain or the other, older ones tend to use both hemispheres. Besides keeping them sharp, this neural integration makes it easier for healthy mid-lifers to reconcile their thoughts with their feelings. As our ageing brains grow wiser and more flexible, they also tend toward greater equanimity. But one can’t sit back and expect wisdom and contentment to flow automatically. Research has identified several types of activities, which if practised regularly, help boost the powers of the ageing brain.Achieve mastery. Mastery over a skill or job is the most important factor deciding a person’s self-efficacy, especially in today’s world. Success experiences raise one’s sense of self-efficacy, failure lowers it. Practise mastering a skill, doing something or striving to do something at its highest level. People who enjoy a sense of control and mastery stay healthier than those who don’t. The possibilities are unlimited, ranging from learning a new language, playing a musical instrument, to taking up painting or embroidery.Exercise physically. Regular physical exercise leads to increased blood flow to the brain, the production of endorphins, better filtration of waste products from the brain and increased brain-oxygen levels and is consistently linked to increased well-being.Establish strong social networks. People who sustain rich and extended social relationships during the second half of life have been shown to enjoy significantly lower blood pressure, lower risk of stroke and brain damage. Social relationships also reduce stress, anxiety and depression.Fulfil your need for generativity. During middle age, the primary developmental task is one of contributing to society and helping to guide future generations. This leads to a sense of generativity-a sense of productivity and accomplishment. In contrast, a person who is self-centred and unable or unwilling to help society move forward develops a feeling of stagnation.advertisementlast_img read more

Deaf Students to Benefit from Literacy Project

first_img Keynote speaker at the event, State Minister for Education, Youth and Information, Hon. Floyd Green, commended the initiative, which, he said, will ensure greater inclusiveness for the deaf community. Story Highlights More than 400 deaf students in primary and secondary schools are to benefit from a US$2.7-million project aimed at increasing their literacy levels. More than 400 deaf students in primary and secondary schools are to benefit from a US$2.7-million project aimed at increasing their literacy levels.The three-year Partnership for Literacy Enhancement for the Deaf Project is being implemented by the Jamaica Association for the Deaf (JAD) in partnership with the United States Agency for International Development (USAID).Launched on Wednesday (September 13) at the Terra Nova All-Suite Hotel in Kingston, the three-year initiative is being rolled out in nine schools operated by the major service providers of deaf education in Jamaica.These are the Danny Williams School for the Deaf; Lister Mair/Gilby High School for the Deaf; and Excelsior Primary School Integrated Unit for the Deaf in Kingston; Caribbean Christian Centre for the Deaf – Kingston and Mandeville campuses; Jamaica Christian School for the Deaf, St. James; May Pen Unit for the Deaf, Clarendon; Port Antonio Unit for the Deaf, Portland; and St.Christopher’s School for the Deaf, St. Ann.A key objective is to facilitate the development of a Jamaican Sign Language (JSL) curriculum that will be incorporated in schools for the deaf by 2020.Keynote speaker at the event, State Minister for Education, Youth and Information, Hon. Floyd Green, commended the initiative, which, he said, will ensure greater inclusiveness for the deaf community.He hailed the effort to have JSL as a subject in schools across the deaf community by 2020.“To achieve that means that you will have developed a curriculum that can be used in our schools for our hearing-impaired children and can be shared across all our schools. From our perspective at the Ministry, that is critical if we are to ensure that no child is left behind,” he said.Acting Mission Director for USAID, Rebecca Robinson, who brought greetings at the event, noted that the project will assist in developing the capacity of the hearing-impaired community, thereby enabling them to make a meaningful contribution to national development.“The evidence suggests that the deaf has been an underserved population with limited educational opportunities. The timing of this project is impeccable, as it seeks to address the factors that affect language development of deaf students and build a strong foundation for literacy and academic success. Also, it helps to enhance the skills of students, parents and teachers in JSL,” she said.The Partnership for Literacy Enhancement for the Deaf Project got under way in April 2017 and will run until April 2020.In addition to increasing the literacy levels of students and establishing a JSL curriculum, the project will also build the capacity of teachers and empower parents to effectively communicate with their children.One hundred educators of the deaf and 27 deaf culture facilitators/teacher aides serving the deaf community will receive support, and the project will also provide employment opportunities for deaf persons as tutors.The USAID provided a US$2.4-million grant for the undertaking with the remaining US$300,000 contributed by the JAD and its stakeholders.Operating since 1938, the JAD is a non-governmental organisation, which empowers deaf Jamaicans to become effective nation builders.Persons interested in learning JSL can contact the JAD at 970-1778/9, or visit www.jamdeaf.org.jm for more information. Launched on Wednesday (September 13) at the Terra Nova All-Suite Hotel in Kingston, the three-year initiative is being rolled out in nine schools operated by the major service providers of deaf education in Jamaica.last_img read more
