Science & social responsibility in public health

Epidemiologists and environmental health researchers have a joint responsibility to acquire scientific knowledge that matters to public health and to apply the knowledge gained in public health practice. We examine the nature and source of these social responsibilities, discuss a debate in the epidemiological literature on roles and responsibilities, and cite approaches to environmental justice as reflective of them. At one level, responsibility refers to accountability, as in being responsible for actions taken. A deeper meaning of responsibility corresponds to commitment to the pursuit and achievement of a valued end

Public health ethics is on the map. In the past year, bioethicists and public health practitioners have begun to focus their critical attention on this complex and understudied topic. Much remains to be done. Childress et al. (2002), for example, describe their account of public health ethics as a rough conceptual map of a terrain with undefined boundaries.

Our focus will be on the responsibilities of epidemiologists, a choice made for several compelling reasons. Epidemiology sits at the center of the science and practice of environmental health, and more generally, at the center of public health. Although it is often referred to as a basic science of public health, epidemiology connects the acquisition of scientific knowledge with its application in preventive interventions, programs, and policies. This connection suggests a fundamental question: What are our responsibilities as epidemiologists? Do we, for example, have a joint responsibility to participate in science and to apply the knowledge gained? This is a key concern for us as researchers, health professionals, and as teachers.

The social responsibility of public health professionals is but one of many concerns in the broader picture of public health ethics. It is nevertheless a central concern. As Ogletree (1996) reminds us, responsibility is a concept particularly well suited to flame many key aspects of the ethics of professions faced with making decisions and taking actions in complex situations. These decisions often involve advanced technologies, high levels of specialization, and overlapping areas of expertise and concern among decision makers from diverse educational, political, and social backgrounds, precisely the situation in contemporary epidemiology and public health. In sum, responsibility organizes many (although not all) of public health’s ethical issues in terms appropriate for professional practitioners.

Responsibility has a deeper meaning as well, corresponding to commitment. To be responsible means to be committed to someone or to some thing. Being responsible in this deeper sense involves a commitment to positive action, to the pursuit and achievement of something of value, such as a social good (Jonas 1984). We will return to the notion of social goods in public health. For now, we want to emphasize that responsibility focuses attention on professional commitments

Finally, our inquiry is intended to assist all public health researchers who seek to define their social responsibilities. For those who are involved primarily in environmental health research, we can think of at least two connected and current topics–environmental justice and community-based participatory research.

Two Oled Technologies Amoled And Pmoled

OLED is a new technology that can make thin, efficient and bright displays. OLEDs are made from organic light-emitting materials, and OLEDs do not require any backlight and filtering systems that are used in LCDs. So OLEDs are more simple to make and actually can be made flexible and transparent as well. OLEDs are also very efficient, and companies are working towards OLED lighting – an OLED “lightbulb” will be efficient and thin, opening the way for great new lighting designs.

There are two types of OLEDs used in displays – PMOLED and AMOLED. The difference is in the driving electronics – it can be either Passive Matrix (PM) or Active Matrix (AM).

With Passive-Matrix OLEDs, the display is controlled by switching on rows and columns. When you turn on row number x and column number y, the pixel at the intersection is lit – and emits light. Each time you can choose just one pixel to light. So you have to turn these on and off very quickly. You do so in a certain sequence, and create the desired image. This is somewhat like the interlace-system used in old CRTs, but the control is done pixel-by-pixel.

PMOLEDs are very easy and cheap to build, but they are limited to small sizes (up to 3″, typically). The image displaying is a bit complicated (because of the row/column method). Also the power consumption is not as good as AMOLEDs.

AMOLEDs have a different driver electronics – each pixel is controlled directly. AMOLEDs are more expensive, and much more difficult to create, but can be used for larger displays (current prototypes are up to 40″) and are very power efficient.

The first OLED products in the market used PMOLEDs – these were MP3 players, sub-displays on cellphones and radio decks for automobiles. The displays were small and usually with just one or two colors. When AMOLED panels started to emerge in 2007 and 2008 we have seen these larger displays in mobile video players, digital cameras, mobile phones main displays and even OLED TVs.

PMOLEDs are still very popular – there are more MP3 player sold today with PMOLED than with LCDs. But for larger displays, AMOLED is the best technology, and is growing much more quickly than PMOLED displays. Obviously for larger displays, such as TV, laptop monitors or PDAs, AMOLED is the only choice.

Today there are several companies that are working on technologies that actually close the gap between PMOLEDs and AMOLEDs – offering a sort of hybrid system. The promise is that these displays will be both easy to make and allow power efficient larger displays. We still have to wait and see whether these technologies actually work on commercial displays. One such technology is Dialog’s SmartXtend.

The Importance Of Keeping Accurate Notes In Science

Science is a progressive act. This means that progress in science is a tedious process that requires diligent efforts with respect to record keeping because in the case of every scientist, figuring out everything about a field of study, such as any given sub-niche of chemistry, is impossible, even in a lifetime. Record keeping is of utmost importance and accurate record keeping can and will make the difference between work that is successfully continued by a scientist’s successors and work that is not successfully continued.

In the field of science, all of us stand on the shoulders of giants. In other words, we all learn from our predecessors and build on what they have taught us. However, we are able to learn only from those who have successfully transcribed their knowledge in an accurate and concise fashion so as to facilitate the propagation of the knowledge to those who follow.

Accurate lab notes are a must. Accurate lab notes will have a variety of properties including but not limited to:

An accurate introductory description of the process or processes being studied. For the information following the introduction to be understood in it’s proper context, an accurate introductory description has to be described clearly. Why is this subject of interest? What is the current understanding of the subject and why does it need to be studied further? What questions need to be answered before true progress can be made? All of these question should be covered in the introduction.

Clear and concise methodology. The work that is performed or is to be performed must be clearly spelled out for those reading the notes to understand the important steps to be taken to repeat and confirm the results. Each step must be labeled in detail and must be done so in a way that can be repeated using the notes alone. This is important if results are to be duplicated.

Well documented and understandable results. The results that are discovered by the initial experimenter should also be spelled out in clear detail as they may differ from the results obtained by those following them and trying to repeat their work. If results differ, this should be clearly noted by the scientists attempting to repeat the work and differences in results should also be clearly noted.

Objective conclusions. Conclusions should be recorded and based on evidence and results obtained. If data or results have discrepancies, these should be noted and discussed in the conclusion.

Environmental advantages of Suspended Particle Device Glass Technology

The idea of the “home of the future” usually contrasts with the idea of environmental responsibility. The perception of technology being detrimental to ecologicial stability is slowly being replaced with the advent of smart technologies such as Suspended Particle Device or SPD glass.

What is SPD Glass?

In the area of light control, there are three main technologies: polymer liquid crystal devices (PDLC), suspended particle devices (SPD) and Electro chromic devices (EC). All three may be used to produce smart glass, which is described as a glass that can change its light transmission when a voltage is applied. In a nutshell these technologies control the opacity of glass via a control method (sensors, remotes, wall switches etc) to regulate the amount of light allowed to pass through it. SPD is generally the technology of choice for use in external or solar control windows because of its reliability, price, performance, and manufacturing advantages and aesthetics.

Energy and Lighting Costs

In terms of home and office environment SPD glass facades, windows and skylights can be used to more efficiently reduce the need for air conditioning during the summer months and heating during winter.

The ability to instantly switch the glass to maximize daylight when it’s really needed and to provide controllable solar shading during peak light conditions is valuable and unique. SPD Glass has even advanced to the stage where light sensors can automatically adjust the opacity of the glass according to programmed settings. This low energy electric current saves overall temperature control and lighting costs and also reduced carbon emissions related to building maintenance.

Hygiene and Health

These SPD glass panels provide a hygienic alternative to curtains and blinds as they do not trap bacteria, grime and dust. Easily cleaned surfaces mean both a savings on cleaning agents and a cleaner environment for homeowners and building owners. Taking advantage of healthy natural lighting without the glare is the smart way to reduce eye strain and protect the skin from UV damage.

Maintenance savings

Professionally manufactures Suspended Particle Device technologies such as SPD glass utilise a highly durable, solid-state technology with no moving parts to wear out or break. Sun damage such a fading carpets, artwork and furniture is also greatly reduced making your interiors last longer. If you combine this interior longevity with the longevity of the physical glass itself you have a winning combination for your pocket and for the environment.

LG Sciences Advances Creatine Science

There are many Creatine’s on the market today. How do you choose the most effective? LG Sciences has released an advanced Creatine Complex that is light years ahead of it’s competition. Cold Fusion EX.

With all of the choices out there how can we decide what is the best form if such a thing actually exists. Creatine is an amino acid that is naturally occurring in the body and provides cellular energy and a host of other benefits to both the bodybuilder and general health enthusiast. In fact creatine is even being looked at to provide increased energy and wellness benefits for the elderly. It may provide heart benefits and also increase mental acuity for people that have diseases like Alzheimer’s. Creatine is responsible for turning ADP into ATP which is your body’s main energy supply in the mitochondria. ATP is split to form ADP (losing a phosphate to create energy) and Creatine Phosphate “hangs around” to recharge the ADP molecule so it can be used to create energy again. Any Creatine is converted to Creatine Phosphate in the body, but oddly enough taking Creatine Phosphate as a supplement never really gave the kind of results that were achieved by many other creatine types, so it was effectively scrapped. Creatine is the base product for any bodybuilder looking to increase size and strength. It adds well to any other product and the only thing more basic than creatine is a protein supplement. Creatine helps the muscle cell hold more water, which can expand the fascia of the muscle increasing its volume. So, creatine is useful for strength and stamina by recharging the muscle energy system, it also increases new muscle cells (monohydrate for sure) and increases pumps for a muscle stretching effect. It is the most popular and beneficial supplement ever for bodybuilders.

Here is a basic list of just some of the Creatines on the market:

Creatine Monohydrate this is the original version sold back in the 80’s for improving strength and stamina for weightlifters. It is tried and tested, however it has been replaced with newer and fancier creatine molecules. I HIGHLY suggest supplements still contain some creatine monohydrate for one big reason. Creatine monohydrate is the only form proven in scientific studies to create new muscle cells. There are many studies showing Creatine Monohydrate increases the formation of new muscle cells and one important study showing that other forms of creatine do not have this effect!

Creatine Malate this is creatine bound to malic acid. The preferred form is DiCreatine Malate since that is the only form that is possible, the other forms (tricreatine malate) are usually just creatine monohydrate mixed with straight malic acid. The supposed benefit of Creatine Malate is reduced bloating and increased endurance, since malate is involved in increasing cellular energy by being part of the krebs cycle. Overall, this ingredient has many years of solid anecdotal support and I feel it is a good addition to any creatine blend.

Parapsychology Schools Teach Parapsychic Sciences

Those who are fascinated by the parapsychic sciences should look into parapsychology schools. The word parapsychology is derived from the Latin word “para” (which means beyond) and psychology; it literally means “beyond psychology.” Schools for parapsychology offer instruction in the areas of clairvoyance, psychokinesis, hypnosis, extra sensory perception (ESP), telepathy, and more.

Parapsychology schools allow students to explore a scientific domain that cannot be explained by known laws of physics or biology. A number of schools offer degrees in psychology, anthropology, or other fields allowing for a concentration on parapsychology, often under the guidance of a practicing parapsychologist. There are various levels of education in parapsychology, and students can earn various credentials from parapsychic science schools, such as the Parapsychology Certificate, Diploma of Parapsychology, Bachelor degree in Holistic Studies, or a Bachelor of Science in Parapsychological Studies, just to name a few.

The typical college-level curriculum found in parapsychology schools might include classes such as ethical and legal issues in holistic care, regression therapy, angels, astrology, spiritual development, sound therapy, near death experiences, chakra therapy, spiritual healing, divination, theology, astral projection, vibrational healing, psychic healing, channeling, and even business management! In short, parapsychology courses are diverse and designed to prepare graduates for a lifetime occupation in the parapsychic and paranormal fields.

If the idea of Parapsychology Schools sounds like a path you might be interested in pursuing, take a moment to submit a request to schools found on our website. You could soon be enjoying a whole new career!

How To Build A Greenhouse Grade 7 Science Fair Projects

A greenhouse is basically a structure that has been designed to capture and retain the heat from the sun. It is used to grow plants when the climate does not want to cooperate. Greenhouses can be used in a number of science fair projects and can be used to test concepts from a variety of fields of sciences including engineering, physics, botany and biology.

Project #1 Capturing Heat Energy

In this project the students will be designing a greenhouse that captures heat energy from multiple sources. They will be capturing heat energy from the sun and geothermal heat energy from the ground. This project will require the student to learn about heat extraction techniques related to solar energy and geothermal energy.

Sample hypotheses that can be tested with this project include:
(1) The thickness of the plastic used for enclosing the greenhouse impacts the amount of heat conservation in the greenhouse;
(2) The opaqueness of the material used for enclosing the greenhouse impacts the amount of heat conservation in the greenhouse;
(3) The depth of the insulation on the floor of the greenhouse impacts the amount of geothermal heat conservation in the greenhouse.

Project #2 Growing Radishes

In this project the student will build a greenhouse so that they can grow radishes and conduct experiments on the radish plants during times of the year that are not normally conducive to gardening. Radish projects can look at a number of things. For example, students can try to cross pollinate radishes with another root vegetable like carrots, they can attempt to grow radishes in sand or they can try to manipulate the size of the radish by exposing the plant to 20 hours of light per day.

Project #3 Engineering Greenhouses

For students that are interested in engineering, greenhouse science fair projects can be developed with an engineering focus. For example, students can try to develop a greenhouse using nothing but materials that are normally thrown out or recycled, such as cans, bottles and plastic containers. Students will not only need to design and build their greenhouse, but they will also need to test the effectiveness their greenhouse has in regards to collecting and conserving heat energy.

Project #4 Studying Solar Energy Applications

The final project option will be an application project. Students will be learning about solar energy and how to use this knowledge to harness the suns energy to heat a greenhouse. For this project students will design and build a greenhouse that maximizes the energy delivered by the sun. A good approach for this project is to see if their design can magnify solar energy within the greenhouse to make it effective in cold weather.
