...When we enjoy entertainment or festivals that celebrate medieval life and times, it is the life of royalty, traveling bards, monks of knights that are most often the focus of our attention. Few of us would want to celebrate the lives of peasants and surfs during the middle ages. There is good reason for that. There was little to celebrate about the harsh life poor people endured during this time in history. For the poor, the dark ages really did not end in the way that it did for wealthy landowners, merchants and high ranking clergy during medieval times. It is not an exaggeration that the life of peasants was a constant struggle to survive. That struggle meant a daily life of hard work, harsh taxes and a lifestyle that was filthy and...

...Case-In-Point - Influenza Pandemics Past and Future Julian H. SCI/362 August 9, 2011 D. Lenz Case-In-Point Influenza Pandemics Past and Future “Those who cannot remember the past are condemned to repeat it” (SANTAYANA, 1905) Unintended consequences of humankind’s activities that have led to the spread of the influenza virus during flu season are the lack of dispersing of the vaccine to the poor and homeless, non restriction of travel to or from known areas with high infection rates, and the quarantining of the infected in industrialized areas. Review of the past influenza epidemics and pandemics have shown that the reaction time is far too slow when dealing with such a communicable disease. In the US, the ill are not forced to stay home to prevent the spread of the disease. During the past H1N1 outbreak, travel was not restricted to and from areas with a high infection rate, nor was the border sealed. Scientific or technological activities that are improving the situation are in the area of research and study of influenza. This study has allowed scientists to develop vaccines that often aid in preventing severe illness or death. There are two forms of the vaccine, an inactivated (or killed virus) vaccine delivered via needle intramuscularly, or a weakened live virus delivered via nasal spray. These vaccines are updated every year. Study of influenza is done year round in over 130 national centers in over 101 countries (CDC, 2011) The application of the scientific...

...Life Coaching In The Time Of Need By James Flowers I want to take this opportunity to introduce myself and extend my knowledge and professional expertise to assist you. Our principal asked me to be your mentor for the next couple of months. It is my understanding that you were administratively placed at this elementary school due to some professional issues at your previous school. I know that you have only been teaching for 2 months and thus I would like to help you in any areas that need to be strengthened. Teaching is a challenging career. When you begin teaching, you feel as though all you need to do is to stand up in the classroom and teach. Your teacher educational classes unfortunately did not prepare you for the realities of teaching that often consist of dealing with problem students, aggressive and non supportive parents, difficult administrative staff, back stabbing co workers, as well as the constant planning and organization as an elementary school teacher. After being in the profession for almost 20 years as an elementary school educator with a an undergraduate degree in English and a graduate degree in Education, I am still learning but I know that I have years of experience to share with others to improve their skills.

...Teacher’s Answer Key Guns, Germs, and Steel: Episode 2 Date:______________ Directions: Before viewing the film, read each question below so you know what information and ideas you should be looking for as you watch Episode 2. Record your answers to each question by providing as many facts, details, and examples as possible to answer each question. Be prepared to discuss your answers with the class. 1. At the time that the Spanish conquistador’s invaded the Inca Empire, they were armed with state of the art weaponry. Describe this weaponry. Answers will vary but should include: horses that made them appear like god-like half man, half beast warriors, body armor, guns, and steel swords. 2. What is Jared Diamond’s explanation for why the Spanish had advanced to steel swords while Inca’s were still making tools and weapons from bronze? Answer: Because Europe was geographically close to the Fertile Crescent, they inherited the 7,000 years of metal technology that had been developed there. Because they had a diversified society that allowed for specialization, the Spanish devoted time and effort to producing the longest, strongest, sharpest swords possible. 3. How did the battle tactics used by the Spanish conquistadors help the small army defeat the Inca army that outnumbered it by the thousands? Answer: The Spaniards begin by surprising the Incas, firing their guns and coming out of hiding on horseback. As they rode, the conquistadors used their swords to hack, cut, and stab the Incas...

The most folly thing I did that same night was drink soda when I obviously had to get a good night’s rest because I was leaving for Mexico for the first time in my life. My parents along with my siblings had to take down our suitcases into the truck. The car ride to the airport was really harmonious because it wasn’t that far, plus I was really excited to meet my family over there. At the airport we meet with two of our relatives. It was a devastation my parents couldn’t go with us due to the fact that they didn’t have papers. After a while of waiting it for the airport workers to check our luggage we had to say our goodbyes to my parents. My parents told me and my siblings to...

...Extending Human Life One Chip at a Time COM 172 March 21, 2012 Dr. Yvette Irizarry Extending Human Life One Chip at a Time How long would you like to live? It is undeniably that scientists and technology are predestined to mend and prolong people natural lifespan expectancy. This, due to the emergence and advancements of a new technology era with highly specialized medical doctors, along with; biologists and bioengineers, electronics, chemists and chemical engineers, physicists, and mechanical engineers all working together in an orchestrated choreographed process around the globe. Novelties in nanotechnology, sustained living tissue reproduction, bio-hybrid organ devices and microfluidics platforms have evolved from a concept of fantasy to a revolutionized reality. Available technology has migrated into the medical world, allowing scientists to develop several human organs utilizing microfluidics platform technology. Harvard University has developed a highly refined lung on-a-chip that embodies numerous forms of tissues. “We started with the simplest embodiment of human airway and capillary cells, and then introduced immune cells” (Ingber, 2010, p. 661). The chip consists of micro-channels parted by a malleable micrometer tissue. A single conduit encompasses air sacks lining like human lungs, and the other channel conveys capillaries, and to emulate blood flow, it has liquids flowing. The chip highlights the cells’ behavior and fluctuations when they are stretched....

...Transitions of Time: Comparing Life now to Life Fifty Years Ago. On the edge of the 21st century, man had discovered more ways than one to make this world a better and safer environment for the future generations due to the increasingly advancements of technology and science, civil reform and medical breakthroughs. However, this does not seem so compliant between generations based on life views, beliefs and opinion differences as they continue to induce provocative dialogues such as comparing life now to that of 50 years ago. The conflict “time” between generation always have been a theme for deviating discussions, and as rule; elder generation tend to influence youth's opinion, pretending on the idea that life was coherently better in half of century ago and they passed more simulating and constructive time rather than doing what young generations think is the norm; squandering their youth on petty things such as aspiring to false values. On the other hand; energetic, smart and wise youth generations are disagree with these points of views, considering that they have freedom to gain their own experience, the right to act in a proper manner, and in the end, that is their own turn to save the world today. The following lines of reasoning will examine the ways these mechanisms has influenced the world. As Faith Baldwin once said “Time is a dressmaker specializing in alterations.” Technology advancement is amazing. In 1960, computers were not household items, nor were cell...

...“Life’s not out to get you, despite the things you’ve been through…” A quote I will never forget. As a young aspiring musician, there will always be hardships and sinkholes. Three years of work turned to six, and now to nine. Although I fell apart after these fateful days, my achy bones tell a story along with my tattered clothes from each night after that December. 13 year old Jenaro, a wannabe local musician, has his first show only days away from turning 14. The event drew closer and I envisioned it being the best time of my career, possibly my life. That fateful night brought panic attacks, anger, and my deep seeded self-loathing up front to the masses, and I failed myself. A tightly packed crowd watched on as a younger me broke down under my internal turmoil reaching its boiling point. Repression set in, I was certain I’d never pursue music after that night. Secluded, I hid myself for close to a year after that day. I was humbled by my experience, but deeply I knew I couldn’t just give up forever. Mid way through the spring, my phone vibrated in my...
