Countdown timers

Thursday, November 19th, 2009

For many people, the only way to finish papers and projects is to have deadlines. Deadlines themselves are not always easy to keep track off. One may note down a conference deadline in the diary and earmark a reminder for a few days before. One could also plan email notifications some days before the impending deadline. This way one cannot ignore the deadline as long as one is checking email regularly. One can post the deadline notification on the office wall or if one is overly obsessed on the fridge!

However, if one is really worried that one can still not keep track of the coming deadline, what would be better than a countdown timer. Such a timer is now easily down-loadable on to your Google desk top and also on your personal webpage or blog.

One can set up the timer with name of the coming event and also a brief description of the event. The size of the countdown icon can be changed and even countdown of other looks can be downloaded via Google gadgets. From personal experience, when one sees the counter, it does give you a spring in one’s step. The image of ticking minutes gives you a sense of urgency.

The only problem I foresee is this sense of urgency should not change to panic. One may tend to upload more than a few countdown timers and then all these ticking icons may make you neurotic. That would defeat the purpose of having everything well planned and under control.

PhDs in the insurance industry

Tuesday, July 14th, 2009

I went to a combinatorics meeting recently. Among the technical talks there was one talk by Dr. Angela Koller on graph theory in industry. Dr. Koller is a mathematician by training who had worked as a research assistant at Royal Holloway. She was now part of the business research team as an actuarial consultant in JLT Insurance.

Dr. Koller gave an overview of the aims of her company and her team. The team dealt with dynamic financial analysis, financial modeling, pricing, natural catastrophe modeling, insurance aggregation analysis. She stressed the stability of the insurance industry which is needed where ever there is an insurable interest.

She outlined the mathematical aspect of her role and said that her team-mates had backgrounds from accounting, engineering, physics, computer science, geography and mathematics. There were a couple of PhDs in her team and a good percentage of Masters holders. Dr. Koller presented a few cases where she had to use general mathematical problem solving skills to model and solve problems in risk analysis especially related to catastrophes.

Dr. Koller stressed the importance of gaining the actuarial certification to do well in the Insurance industry. However, she did not plan to get an official certification as she had picked up the required skills and an official certification required a further three to four years of intense study and examinations. She was of the view, that even if an insurance employee is not taking actuarial exams, it is worth refreshing the concepts and regularly consulting the training material.

It was really helpful for her to stay after the talk and answer various questions from final year PhDs concerning the job market. Some one asked if she was using her graph theory training in her job. Although, her PhD did not directly apply to her job, she maintained that it was the skills acquired during her PhD which were valuable. She was of the view, that it is these skills which should be emphasized in non-academic job applications. It was interesting to see that where as most PhD seeking a job in the city turn to investment banking, there are other industries with interesting challenges and rewarding careers.

Presentations and lectures

Tuesday, July 7th, 2009

Gian-Carlo Rota was a well known mathematician of the twentieth century. He was also known for his innovative teaching style. Rota wrote an essay on the things he wished he had been taught. Although, the essay covers a lot of bases, I will briefly comment on Rota’s main advice on giving talks/lectures/presentations:

  1. Every lecture should make only one main point: One mistake which we all are prone to making is putting too many things in a single presentation.  A presentation is more effective if there is a single theme and the theme is explained gently and highlighted by examples. Rota, gives the analogy of the audience as a cow herd which needs to gently steered to the central point.
  2. Never run overtime: Rota really stresses this point. It is true that even if a presentation is great, it can be irritating for the audience if the speaker does not keep track of time. Interestingly, in a conference I attended, the program chair stressed the same point but ended up running over time in her own presentation. One could hear chuckles in the room.
  3. Relate to your audience: Rota also writes that making a connection with audience is helpful. It is certainly helpful in breaking the ice, easing the nerves and also making the presentation more personalized and conversational. The talk should be tailored according to the audience. Yeats once said, “Think like a wise man, but communicate in the language of the people”.
  4. Give them something to take home: This is one consistent habit, I have witnessed in all good speakers. Some speakers even emphasise to the listeners they might want to listen to a certain particular point as the take home message. The take home message also pleases the listener as one can remember something useful from an involved talk.

PowerPoint slides

Monday, April 27th, 2009

The stereotypical PowerPoint presentations with monotonous design, lots of bullet points and topic-subtopic structure have received much criticism. This has been covered in the New York Times. Similar concerns have been voiced in Wired Magazine and the Chicago Tribune. Whereas some authors may complain more about the monopoly and ubiquity of certain presentation software, one strong criticism has been on the presenter being forced to think and present in a rigid way which is difficult to absorb by the audience. Edward Tufte is specially scathing in his attack:

With so little information per slide, many, many slides are needed. Audiences consequently endure a relentless sequentiality, one damn slide after another. When information is stacked in time, it is difficult to understand context and evaluate relationships. Visual reasoning usually works more effectively when relevant information is shown side by side. Often, the more intense the detail, the greater the clarity and understanding. This is especially so for statistical data, where the fundamental analytical act is to make comparisons.

It is easy to criticize but what is the solution? In terms of alternate presentation methodology, there is a lot of literature. One recurrent theme is the ‘assertion-evidence design’. The assertion-evidence design is aimed to rectify two problems in traditional designs namely unclear assertion and unclear linking of evidence:

For one thing, identifying the main sentence assertion of each slide requires more thinking than simply identifying the slide’s topic word or phrase. In addition, coming up with cogent visual evidence to support each assertion is more demanding than coming up with a bullet list of subtopics for each slide topic. Another hurdle to adopting the design arises from overcoming the weak defaults of PowerPoint for type size, type placement, text anchors, bulleted text, and distracting backgrounds.

The conclusion is that irrespective of one having strong feelings for or against specific softwares, a ‘bullet-point ridden’ presentation is not ideal. Complex ideas require innovative presentation and logical flow. Finally, the main message of the presentation should always be emphasized by well chosen headings and backed by useful pictures.

Emails and time management

Friday, March 27th, 2009

Emails are an integral part of professional life and well composed emails concerning business proposals, meetings plans or exchange of ideas can get a lot of work done in a few clicks. However, how many times have you sat in the office and realized that you had not done much in last half an hour other than check emails? One often has this urge to refresh one’s inbox in expectation of some important email or glance to the alert box even if one if working on something else. So there is always a dilemma on whether one is managing one’s time well with respect to emails. It appears that this issue is more universal than one could have thought. The New York Times has an article on managing one’s emails efficiently. (more…)
