essay: looking at media

Critically assess and evaluate a media piece

The media is our portal to the world. Before the internet become popular, the media was, in fact, the only portal to the world. All news reports and opinion pieces could only be distributed by the media. Back then, using Gillmor’s metaphor of information as an ocean (Gillmor 2004), big media companies were truly the only ports where one could access the oceans. With prevalence of the internet, the recipients of information have also become the contributors. The oceans have flooded the ports, and now almost everyone can reach out to the ocean if they cared. However, the entrenched notion that traditional media companies are correct and authoritative in their reporting has remained with us to this day. This is extremely dangerous because, as our readings have shown, the advertisements and big corporations have power like never before to influence, or filter, what gets published and what doesn’t. Most of us have failed to critically think about what the news tell us, sometimes unconsciously, and how our opinions are altered. We usually do not have enough time to research into every piece of news and make an informed decision. One particularly interesting scientific study has shown that even the subtle facial expressions of a news reporter on television can influence people’s votes on presidential candidates in the United States, regardless of how neutral the news report was (Mullen 1986). The written word, such as using “loot” instead of “find”, probably has an even larger effect than facial expressions.

Essay: Conservation and Moderate Scarcity

Conservation and Moderate Scarcity

Tiffany Tong
October 15th, 2007

The concept of conservation promotes protection of natural resources to balance consumption and preservation so that future generations will have sufficient resources to utilize[1]. Conservation, however, can only deal with resources that are “moderately scarce” relative to human wants, and cannot be applied to resources that are extremely abundant or scarce relative to human wants[2]. In both extreme cases, conservation fails to be implemented because it is a relative concept that offers no concrete limit or guidelines, and only implies, but does not enforce, a constraint on human activities.

Conservation as a relative concept tells us how our actions should be relative to what we could have done otherwise2. It, thus, implies that there should be a constraint on human desires and actions2. Conservation tells us that although we have the ability to use up all our natural resources today, we should constrain our immediate wants, and spread out our consumption in order to leave some for tomorrow. Yet, the problem is that, since our usage is relative, there are no concrete limits to restrict our consumption, even when over harvesting of resources can bring negative consequences.

In cases where the resource is very scarce relative to human wants, non-binding constraints will break down and will not be able to be enforced. When there is an extremely high level of desire for a particular resource, its market price will rise. If there are very strict laws governing the protection of that resource, the market price will only increase even more because of scarcity. Thus, even if breaking the constraint will result in, for example, a death penalty, the risk of one’s life would still outweigh the benefits of earning an equivalent of many years worth of money to support one’s family2. Therefore, when immediate human wants far outweighs the long term goal of conservation, no kind of constraint can be enforced to protect the natural resource.

One example of a resource of extreme scarcity is illegal logging of mahogany in Brazil. The huge demand for mahogany furniture, piano, and guitars, which are known for their beauty and hardiness, in the international market has led to huge discrepancies in the numbers exporters and importers of mahogany report: much more is imported than exported legally (Greenpeace 2001). The Brazilian government estimated in 2001 that 80% of all logging done in Brazil was illegal (Greenpeace 2001). Even with strict laws and hefty fines in place, the illegal trade is still rampant because mahogany is scarcer than human wants.

In cases where there are plentiful resources relative to human wants, humans will have no desire to consume all of the resource. Therefore even if no constraint is required to protect that resource, there will still be enough for future use. In other words, there will not be a large market for the resource and thus no high prices to drive people to break down any constraints.

An example of an abundant resource is silicon. On earth, silicon is the second most abundant element, making up 25.7% of the earth’s crust by mass (Chemistry). Silicon is also very useful because it is the principal component of most semiconductor devices such as microchips that are essential to the functioning of computers (Chemistry). Although there is a huge and increasing demand for silicon, the supply is equally abundant. Therefore conservation does not apply to its protection; no regulation or constraint is required for the protection of silicon as a resource.

Essay: mongolian grasslands


Mongolian Grassland Degradation as an Environmental Issue

Tiffany Tong
October 5th, 2007

An environmental issue is defined as “a clash of interests in which someone causes or will cause a harm or perceived harm on someone else’s interest by way of the natural environment1.” The principle theme of the Mongolian grassland degradation problem has all the main components of an environmental issue: conflicting lifestyles and harm caused to all the inhabitants of the grasslands.

The clash of interests occurs between the new and old lifestyles of the Mongolian plains. Traditionally, the lifestyle was centred on the principle “love nature as your parents (Moyers 2001).” The size and health of one’s herd represented one’s wealth (Moyers 2001); herders had the incentive to take good care of the grasslands which supported their herds. Both traditionally and under communist control, rotation of grazing land was practised and flock size was kept to an optimum. When the Soviet Union collapsed, however, the economy became a market economy, and started to be driven purely by profit. Now the new symbol of wealth is money. Herders have started to decrease rotation, to increase herd size, and to keep more animals for profit rather than sustenance, like goats for cashmere (Moyers 2001).

The new practices ultimately harm all the herders, since their livelihood is totally dependent on the resources the natural environment provides. Rotation used to be sufficient in letting the grass grow again after a grazing season, but now the fields seem constantly barren. As one elder said, the grass used to grow up to his stirrups when he was young; now it is barely 3 inches high (Moyers 2001). Moreover, the spread of Western culture encouraged people to settle down close to large roads, where transportation is more convenient (Moyers 2001): less mobility of the herders means higher strain on the grasslands (Moyers 2001). As a consequence, the grassland degradation problem is increasingly becoming an environmental issue that has a major effect on the future of the Mongolian people.

Essay: conservation a normative concept

Why is “conservation” a normative concept?

Tiffany Tong

September 28th, 2007

Conservation is a normative concept because the principles of conservation are based on value judgements that cannot be rationalized or proven true, except by the norms of a society. First of all, conservation is the ideology that promotes protection of natural resources to strike a balance between consumption and preservation so that enough resources will be available for future generations to use and enjoy1. In addition, a normative concept is where a norm, or a cultural standard, is backed with good reasoning, and usually strong scientific evidence, to become a guiding principle for society’s actions2. Normative concepts are prescriptive: they talk about what we should and ought to do, as opposed to descriptive statements which attempts to describe reality as it is. They are essentially a value judgement made by the society as a whole, regarding which actions are right or wrong, good or bad, and which actions we should prioritize (Wikipedia). Therefore, by definition, conservation is a normative concept because it judges the value of our environment and descendants by the norms of our society and results in statements about what we should or ought to do in order to preserve those values.

Normative concepts are so abundant and ubiquitous in most societies that we normally do not think deeply about their implications. Taking conservation for an example, one might ask, “Why do we have to think for future generations?” Or “Why do we believe nature is important and should be preserved?” The answers to these questions cannot be logically deduced without coming back to the fundamental premise that it is the norm, or the “correct” way, to do so. Hence, if our society thought that either future generations or nature is not important, then we might not even have the concept of conservation at all.

Essay: beauty and the dove campaign

New Saviour or New Suppressor?

Tiffany Tong

November 15th, 2006

Only 2% of [surveyed] women describe themselves as ‘beautiful’; almost one half of them think their weight is ‘too high’.

Dove Campaign for Real Beauty Website (“Dove”)

The above findings are from a Dove initiated survey of 3,200 women aged 18 to 64 from ten countries including the United States, Canada, and Japan (“Dove”). In response, Dove launched a new advertising campaign in which the city bloomed overnight to reveal eye-catching billboards. It turned heads not because of its stick-thin, sexy female models, but because of it featuring models with thick, round thighs and full stomachs that curve out instead of in. The different coloured women, in pure white underwear, laugh with their mouths wide open. Confident, natural, basic are the first words that come to mind.

Essay: Nature as Teacher

Nature as Teacher:

Ecosystem Characteristics Applied to Urban Settings

Tiffany Tong

November 15th, 2006

Treat the earth well: it was not given to you by your parents; it was loaned to you by your children. We do not inherit the Earth from our Ancestors, we borrow it from our Children.”

Ancient Indian Proverb

Introduction

The earth’s condition has been deteriorating since the industrial revolution (Hails). Global warming, pollution, peak oil, ozone layer depletion and many others have become household terms. The most famous international environmentally friendly protocol, the Kyoto protocol, has been signed for 8 years. Yet, not only has Canada failed to meet its goal of reducing 6% of carbon dioxide emissions from the 1990 level, but instead, is has actually gone up 24% (CBC News). Our current ecological footprint analysis tells us that for everyone in the world to live a Canadian lifestyle-that is with large sprawling urban areas and more than one car per family-we need the total resources of 4.2 Earths (the ecological footprint per capita in Canada is 7.6 hectares when the biocapacity is 1.8 hectares) (Hails). Although words such as sustainability or ecological footprint are tossed around, by most people, casually and without real meaning, I believe it has come to a time when these terms should be treated by all with serious respect and, accordingly, take action to help prevent a global crisis happening. Where should we start? By thinking and being sustainable.

Title: Mapping the Echoes of the Echo Circle at Wyman Plaza

Author: Tiffany Tong

Abstract

The echo properties of the Echo Circle at Wyman Plaza of the University of British Columbia were measured with two wooden sticks as a sound source and Audacity as the recording program. The results provided support to the hypotheses of the middle platform being the focal point of the circle and of the sound waves reflecting off the right angle of the circle to form echoes.

Introduction

The Echo Circle at Wyman Plaza of the University of British Columbia has very interesting echoing properties. If one stands on top of the platform in the middle and makes a sufficiently loud sound, one can hear its echo on the platform, but nowhere else. My hypothesis is that the sounds waves made inside the circle bounce off of the right angles made by the circular seats around the platform and reflect back to the original place where the sound was made. Also, the middle of the circle, where the platform is, should be the focal point of the circle-the echoes should have the largest intensity at the focal point. In this experiment I used the program Audacity to measure the time intervals between the spikes in the graphs, which indicate echoes, to determine where in the circle the sound sources reflect.

wow…still dreaming

Hello blog,

I think I’m still dreaming. I just woke up from a dream where I went to live in a village in rural Tanzania for two months. I remember lots of goats, people, and orphans. And wait, when I woke up, I found this on my computer…

thesis

Abstract

Conducted for the Programme for Agricultural and Natural Resources Transformation for Improved Livelihoods (PANTIL), this research endeavour was aimed at improving upon a dairy goat project for orphans in the villages of Nyandira and Ndugutu in Mgeta, Tanzania. Over a period of six weeks, I collected qualitative data using an action-based research approach in hopes of catalyzing a successful implementation process. The results indicate that the orphan-goat project can provide both immediate and enduring assistance to the orphans; however, the project needs much more community support. At the end of my fieldwork, many stakeholders have agreed upon establishing institutions to ensure a fair, accountable, and efficient process of distributing benefits from the project to the orphans. Concrete short- and long-term goals and a timeline for implementation are set. Financial sustainability is found to be possible without additional funding. Finally, risks and corresponding mitigating strategies have been discussed with the project steering board so that future problems can be anticipated and avoided.
