"The Aging of Public Transportation Systems" by Matthew Minerd (2013)

As cities develop, their public transportation systems often show signs of aging that are mixed with aspects that are quite up-to-date. An example of such a situation can be found in the transportation system in Washington DC. This system is made up of a mixture of buses and trains that connect people to locations in DC, Maryland, and Virginia. While the system has been well maintained and updated over the years, it still shows evidence that certain sections are older than others.

This is particularly noticeable when one considers the multiple lines that connect in Washington DC itself. Within the city, there are five different sets of tracks that run in various directions and to sundry places. A number of the newer lines are in excellent condition and rarely break down; however, the case of the red line is somewhat different. This oldest line of the metro train system often has issues because of its age, experiencing a number of track and signal issues even at rush hour when the overall system is its most efficient. Admittedly, the transportation authority is working to update this line and make it less problematic. Still, until this work is completed, it is obvious to all who are familiar with the metro train system that the red line is the oldest and most out of date.

"Why Learning Multiple Languages in Graduate School is Important" by Matthew Minerd (2013)

In graduate school, students are often required to learn a number of foreign languages in addition to their regular coursework. This can be quite frustrating and difficult, for the normal courses in graduate school require significantly more reading and writing than do undergraduate courses. It is not unusual for graduate students to have regular reading assignments of several hundred pages for each course that they take. Likewise, they often write papers of much greater length than those that they wrote as undergraduate students. When language examinations are added to this difficult course load, it can be very frustrating for graduate students to try to find the time to prepare for these additional examinations.

Although these frustrations are understandable, this system has not been created solely to cause woe for graduate students. Much of the work for which these students are being prepared will focus on research. While much has been written in English about many topics, adequate research can only be done if one is able to read what people have written in other languages. For instance, there are many important articles and books written about almost every topic by European scholars. If a graduate student does not know any foreign languages, all of these article and books will be impossible to read, and hence useless to their research endeavors. This would be a great loss for a student's research. Therefore, in spite of its frustrating aspects, the language examination process is an important component of graduate school education.

"Addictions" by Matthew Minerd (2013)

Addictions come in many forms, often quite hidden from those who should be aware of them. It is helpful to be aware of how hidden these obsessive behaviors can be. Often, they appear to be harmless, but this appearance is deceptive. Perhaps several examples can assist in increasing the reader’s awareness of these potentially problematic habits.

A very simple example of such an apparently innocuous addiction is the addiction that many people have to a beverage like coffee. While not as destructive as an addiction to alcohol, an extreme need for caffeine often covers a need for more sleep or an overzealous desire to be completely energetic at every waking moment. Also, a great deal of caffeine can potentially do damage to one’s heart due to the stress caused by its stimulating effects.

Another example of a seemingly harmless addiction can be found in the case of people who are addicted to work. It is very tempting to praise such obsessive behavior, as it provides many benefits for others and even for the one doing the work. The advancement of a career certainly seems beneficial and often allows for great personal and financial fulfillment. Nevertheless, constant work often hides some sadness, insecurity, or fear that should be confronted by the person who slaves away without cessation. Likewise, over time, such continuous work often can be greatly destructive of important personal relationships.

Of course, many more examples could be brought forth, for one can obsess over almost anything. Still, even these two simple examples should make clear to the reader that it is possible for there to be apparently harmless—indeed, seemingly helpful—life practices that in reality can pose a potential harm to one’s physical or mental well-being.

"Soccer" by Daniel Morrison (2014)

Soccer is considered by some Americans to be a European and Latin American sport. For numerous reasons, the sport has struggled to take hold professionally in the United States, but there is growing participation in the sport at the youth level. This can probably be attributed to the relative dangers faced by those playing soccer and those playing America’s traditional favorite youth sport—American football.

Young children who play American football are at high risk of several catastrophic injuries such as concussions, fractures and spinal damage. The universal concern among parents to protect the health of their children has lead many to encourage their child to take up soccer as opposed to American football. If this trend continues, which it almost certainly will as our society becomes more aware of the degree of damage done by repeated collisions in American football, it will not be long before the popularity of soccer spreads upwards to the professional level.

"The Dangers of Sugar" by Daniel Morrison (2014)

Sugar is a highly addictive substance that plays a dangerous role in the health and well-being of people around the world. It is particularly threatening to American health, as it is placed in everything from carbonated sodas to beef jerky and vegetable juice. The average American consumes seventy-five pounds of sugar every year—that is roughly the weight of a elementary school child. Many health experts believe that sugar is the number one contributing factor in the high rates of obesity, heart disease, and diabetes that can be found in the contemporary United States.

Why does the author believe that sugar is “particularly threatening to American health”?

Adapted from "The Dartmoor Ponies, or the Wandering of the Horse Tribe" by Arabella B. Buckley inA Book of Natural History(1902, ed. David Starr Jordan)

It was a calm misty morning one day last week, giving promise of a bright and sunny day, when I started off for a long walk across the moor to visit the famous stone-circles, many of which are to be found not far off the track called Abbot’s Way, leading from Buckfast Abbey to the Abbey of Tavistock.

My mind was full of the olden times as I pictured to myself how, seven hundred years or more ago, some Benedictine monk from Tavistock Abbey paced this narrow path on his way to his Cistercian brothers at Buckfast, meeting some of them on his road as they wandered over the desolate moor in search of stray sheep. For the Cistercians were shepherds and wool-weavers, while the Benedictines devoted themselves to learning, and the track of about twenty-five miles from one abbey to the other, which still remains, was worn by the members of the two communities, the only variety in whose lives consisted probably in these occasional visits to each other.

Yet even these monks belonged to modern times compared to the ancient Britons who raised the stone-circles over the moor; and my mind drifted back to the days when, long before that pathway was worn, men clad in the skins of beasts hunted wild animals over the ground on which I was treading, and lived in caves and holes of the ground.

I wondered, as I thought of them, whether the monks and the ancient Britons delighted as much in the rugged scenery of the moor as I did that morning. For many miles in front of me the moor stretched out wild and treeless, while the early mist was rising off the hill-tops. It was a pleasure, there on the open moor, with the lark soaring overhead, and the butterflies and bees hovering among the sweet-smelling furze blossoms, to see horses free and joyous, with no thought of bit or bridle, harness or saddle, whose hooves had never been handled by the shoeing-smith, nor their coats touched with the singeing iron. Those little colts, with their thick heads, shaggy coats, and flowing tails, will have at least two years more liberty before they know what it is to be driven. Only once a year are they gathered together, claimed by their owners and branded with an initial, and then left again to wander where they will.

The rowboatFox纽约港,由乔治·Harbothirty-one years of age, captain of a merchantman, and Frank Samuelson, twenty-six years of age, left New York for Havre on the sixth of June. Ten days later the boat was met by the German transatlantic steamerFürst Bismarckproceeding from Cherbourg to New York. On the eighth, ninth and tenth of July, theFoxwas cast by a tempest upon the reefs of Newfoundland. The two men jumped into the sea, and thanks to the watertight compartments provided with air chambers fore and aft, it was possible for them to right the boat; but the unfortunates lost their provisions and their supply of drinking water. On the fifteenth they met the Norwegian three-masted vesselCito, which supplied them with food and water. The captains of the vessels met with signed the log book and testified that the boat had neither sail nor rudder. TheFoxreached the Scilly Islands on the first of August, having at this date been on the ocean fifty-five days. It arrived at Havre on the seventh of August.

Cost what it might, the men were bent upon reaching this port in order to gain the reward promised by Mr. Fox, of thePolice Gazette. Thanks to the wind and a favorable current, they made one hundred and twenty-five miles in twenty-four hours. One slept three hours while the other rowed. Their skins and faces were tumefied by the wind, salt water, and sun; the skin of their hands was renewed three times; their legs were weakened; and they were worn out.

Adapted from "Errors in Our Food Economy" inScientific American Supplement No. 1082Vol. XLII (September 26th, 1896)

Scientific research, interpreting the observations of practical life, implies that several errors are common in the use of food.

First, many people purchase needlessly expensive kinds of food, doing this under the false impression that there is some peculiar virtue in the costlier materials, and that economy in our diet is somehow detrimental to our dignity or our welfare. And, unfortunately, those who are most extravagant in this respect are often the ones who can least afford it.

其次,我们所吃的食物并不总是有限公司ntain the proper proportions of the different kinds of nutritive ingredients. We consume relatively too much of the fuel ingredients of food, such as the fats of meat and butter, and the starch which makes up the larger part of the nutritive material of flour, potatoes, sugar, and sweetmeats. Conversely, we have relatively too little of the protein of flesh-forming substances, like the lean of meat and fish and the gluten of wheat, which make muscle and sinew and which are the basis of blood, bone and brain.

Thirdly, many people, not only the well-to-do, but those in moderate circumstances, use needless quantities of food. Part of the excess, however, is simply thrown away with the wastes of the table and the kitchen; so that the injury to health, great as it may be, is doubtless much less than if all were eaten. Probably the worst sufferers from this evil are well-to-do people of sedentary occupations.

Finally, we are guilty of serious errors in our cooking. We waste a great deal of fuel in the preparation of our food, and even then a great deal of the food is very badly cooked. A reform in these methods of cooking is one of the economic demands of our time.
