Is there 100 percent safe sex in our lives?

January 7th, 2007

Sexual Health in more and more important in Medicine since sex is getting a more and more hot topic in our society.

From Yahoo, examples of high-risk sexual behavior include:

  • Unprotected intercourse without male or female condom use, except in a long-term, single-partner (monogamous) relationship.
  • Unprotected mouth-to-genital contact, except in a long-term monogamous relationship.
  • Early sexual activity, especially before age 18.
  • Having multiple sex partners.
  • Having a high-risk partner (one who has multiple sex partners or other risk factors).
  • Having anal sex or a partner who does.
  • Having sex with a partner who injects or has ever injected drugs.
  • Exchange of sex (sex work) for drugs or money.

    “Unprotected mouth-to-genital contact, except in a long-term monogamous relationship”, this surprises me. Is this because of bacteria or enzyme?

Really. So the only low risk sex here is protected intercourse in a long-term single-partner relationship. By the way, male condom is not 100% effective in preventing STIs/HIV/AIDS and pregnancy. It about 80% effective with a large range 35-94% (Weller and Davis; Hearst and Chen 2004).

Is there 100% safe sex in our lives? NO.

However, sex can be safer.

Vaginal sex and oral sex are safer than unprotected insertive anal intercourse (UIAI) (Vittinghoff E 1999).

Having sex with a non-injective-drug user is safer than having sex with a partner who injects.

Having single partner is safer than having multiple sex partners.

And, if a person have zero sexual desire, BINGO!

A good book about high risk sexual behavior is :

Writing Aims and Objectives

January 2nd, 2007

Writing Aims and Objectives

What are the differences between aims & objectives?

Writing useful and appropriate aims and objectives isn’t an easy task, made more difficult by the imprecise definition of the terms and vague distinctions between the two.

We can think of aims as broad general statements of what students are expected to learn.

Aims are often more appropriate for courses than for subjects. An aim for a course may be, “Students should acquire skills of economic analysis and reasoning” or, “Students should develop the ability to think creatively and independently about new engineering problems”. A course may have a number of broad, often esoteric, aims. Aims may include abstract concepts such as ‘professional qualities’ or ‘appreciation of the classics’, learning that may be difficult to measure but which is nevertheless important.

Objectives are usually more specific statements of the learning which will occur, generally within a subject, lecture or task. Objectives are not statements of content or topics, nor are they statements of the intended teaching strategies; rather, they are statements of what a student is expected to know and be able to do upon completion of the learning exercise. An objective for a subject may be, “The student should comprehend the relations among fundamental concepts in Newtonian mechanics” or, “The student should understand the principle of equilibrium in Keynesian macroeconomics”. The best objectives will neither be too vague nor overly precise. There is a skill in maintaining this balance.

There are a range of approaches for defining objectives.

One approach is to limit objectives to statements of behavioural objectives; that is, if the objective has been achieved, there must be a clearly observable outcome. Generally, however, objectives need not focus solely on observable behaviour. When we teach, we aim to develop understandings and attitudes that may be difficult to measure.

Competency based objectives represent another approach to expressing learning outcomes. This manner of stating objectives adds a further two elements to the previously mentioned essential parts of an aim or objective statement: a measurable performance standard, and the conditions under which the objective is to be achieved. To illustrate this using the introductory example, using a competency based approach the objective would become “repair within ten minutes using the correct tools a dripping tap which requires a new washer“.

An approach to writing learning objectives relevant to the nature of a particular subject or course should be chosen

A Brief Summery

So, an aim is a general statement of intent. It tries to summarise, in broad terms, the activity which is about to take place. Aims are written in general terms. Once you have established your aims it is them important to break these down into small, achievable chunks. These are called objectives.

An objective is a description of an intended outcome, written in specific terms. It describes:

  • What you will do.
  • By when.
  • Using what (resources, equipment, facilities).
  • To what standard.

Objectives need to be SMART!

Specific.
- You know exactly what it is you have to do (not just ‘find out about‘).
Measurable.
- You know when you’ve got there or you have done it.
Achievable.


- It is possible to do them in the time and with the resources available.
Realistic.
- It is possible to do them, they are not based on fantasy.
Time bounded.
- You set a time limit on them (otherwise you might never get around to it).

Examples of Verbs used for “aims” and “objectives”

describe

determine

discuss

It’s not a very scientific categorising. Some verbs, of course, can be used for both objectives and aims depending on objectives and aims of your thesis.

A Definition of Sex Work

January 1st, 2007


I saw the picture from BAYSWAN. Sex work is regarded as one of the oldest industries in this world. It’s not really true, maybe. However, we can not deny that sex is our nature since reproduction is human being’s top one demand and responsibility.

Money stands for commercial exchange. Exchanging is the most basic form of economy. Combining the two, we got sex work here. Sex work, or prostitution, is the provision of sex services for money or its equivalent. (C. Harcourt and B. Donovan, 2001) .

Becoming a Full Professional

January 1st, 2007

Estelle M. Phillips and D.S. Pugh, How to Get a Ph.D,1987

The holder of a doctorate is someone who is recognized as an authority by the appropriate faculty. In modern terms it is useful to think of this as becoming a full professional in your field. Let us try to spell out what becoming a full professional means:

First, at the most basic level it means that you have something to say that your peers want to listen to.

Secondly, in order to do this you must have a command of what is happening in your subject so that you can evaluate the worth of what others are doing.

Thirdly, you must have the astuteness to discover where you can make a useful contribution.

Fourthly, you must have mastery of appropriate techniques that are currently being used and also be aware of their limitations.

Fifthly, you must be able to communicate your results effectively in the professional arena.

Sixthly, all this must be carried out in an international context; your professional peer group is worldwide. You must be aware of what is being discovered, argued about, written and published by your academic community across the world.

So, if you are a currently Ph.D candidate, you’d better review what you did and what you are doing now always and ask

“Am I adequate now?”

I am not.
