The hand that rocks the boardroom cannot rock the cradle free essay sample
The hand that rocks the cradle can rock the boardroom. After being raised by a mother who? s time has been mostly spent working and trying to run a business, it is definite for me that a working mother can not expect to be good mother. Comparing my working mother? s job as a mother to my friend? s mothers who spend all of their time and energy focused on raising their child, makes it crystal clear that the characteristics needed to be a good mother, at least from my point of view, are not completed by my mother. It is just out of the question, either you do one thing properly or the other. Mothers canââ¬â¢t expect to have to completely different jobs that require their complete attention and excel at both. Either they do one thing or the other. In order to be a salient mother, attention or just the simple act of being present throughout their children? s day is very necessary. We will write a custom essay sample on The hand that rocks the boardroom cannot rock the cradle or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page For most hard-working mothers, babysitters, or in some cases day care, are their sweet escape from having to deal with their children; what they donââ¬â¢t know is that the more they depend on the babysitters to meet their children? s need for attention, the more distant they grow from their children. Since having a job or running a business draws most of a mother? s attention, it is impossible for her to think that she is doing a good job as a mother. All of this attention is being given by the babysitter, therefore making her play the role of a mother in the child? s life and creating a vast distance between the child and the mother. It is most important for a mother to be present in her son or daughter? s life physically as crucial as it is for her to be there mentally. It is frustrating for any child to lack the presence od a mother in their life. The nanny or the babysitter fills in this gap, but it still doesnââ¬â¢t suffice for the huge abyss. Simple things like taking their kids to soccer, or assisting their school reunions are not most likely to be done by a busy woman. These things are mildly important because they build a sufficient amount of confidence between the mother and child and make their bond stronger. As motherhood is affected by working, working is also affected by motherhood. Mothers claim to say that they can multitask, but is this true? For most mothers, their kids mean everything to them which means that they think sufficiently about them. This is a clear impediment for efficient work and is proved to be true. How can a mother expect to be good at her job when she is thinking about her kids the entire time? Mothers have the trait of being very precarious, and leaving their precious kids to the care of someone else who will probably not take as good care of them would only amplify that. The fact that a mother is a mother doesnââ¬â¢t mean that she is her child slave o that she has to devote her entire life to him or her, it is more about the small and unnecessary details that a devoted mother shows that not only make her a mother, but a true friend.

Report Essays - Chemistry, Catalysis, Peroxides, Hydrogen Peroxide
Enzymes: Catalase in the Liver and How it Reacts When Exposed to Hydrogen Peroxide Rainy M. Williams Jmeah Clark Saint Augustine's University Key Words Substrates Products Enzymes Catalase Hydrogen Peroxide Denaturalization Optimum Range Abstract All organisms rely on enzymes to catalyze a chemical reaction. An enzyme is a biological catalyst that increases the rate of a chemical reaction by lowering the level of activation energy that is necessary for the reaction to begin. Without enzymes, all chemical reactions necessary for life would proceed very slowly and would require more energy. If a substance (hydrogen peroxide) is added to an enzyme (catalase found in the liver), the reaction will speed up by bringing the reactants ( in this case, the substrates) within close proximity and facilitating their interaction when undergoing the reaction. The liver contains a specific enzyme called catalase.When hydrogen peroxide (H2O2) is added to the liver, the reaction is catalyzed due to the catalase, causing a chemical reaction to occur (essentially detoxifying the cells containing hydrogen peroxide), creating the products of water and oxygen. Introduction A substance that speeds up a reaction - without being a reactant - is called a catalyst. Catalysts used for biochemical reactions are known as enzymes, which are generally proteins. When enzymes are present in a reaction, the enzyme lowers the level of activation energy which is necessary for the reaction to begin. Enzymes work by binding reactant molecules and holding them in such a way that chemical bond-breaking and bond-forming can occur more readily. In order to catalyze a reaction, the enzyme will "grab" one or more reactant molecules to undergo the reaction. These reactants are called substrates, as they need the facilitation of an enzyme to complete the reaction. The part of the enzyme in which the substrates bind to the enzyme is the active site. The active site is the area in which the catabolic action occurs.The set of amino acids found in the active site as well as the 3D space give the enzyme its specific shape, size, and chemical behavior. An enzyme's active site is uniquely suited to bind to only one substrate in order to undergo the reaction ( Khanacademy.com). Once the enzyme and substrate combine, the enzyme quickly breaks down the substrate. The enzyme, however, is not consumed during this reaction, meaning the enzymes are reuseable. The substrate in this lab is hydrogen peroxide, a toxin found in the cells of all living organisms. Catalase, the enzyme for hydrogen peroxide (H2O2), accelerates the breakdown of hydrogen peroxide into the products of oxygen and water. The chemical equation for this reaction is: 2H2O2 2H2O + O2 The main objective of this lab was to determine how a piece of liver - which contains the enzyme catalase - would react when exposed to hydrogen peroxide (the substrate) in different food items and temperatures. If hydrogen peroxide is added to different food items such as an apple or potato, only a moderate reaction rate will occur compared to the rate of the raw liver. The food item is the independent variable of this lab, thus meaning the food item being tested -raw liver, apple, or potato - will be able to manipulate the outcome of the dependent variable which is the reaction rate. Part two of this lab was to determine the rate of reaction when the catalase was exposed to the hydrogen peroxide in differing temperatures of H2O2 (ice water (0c), room temperature (21c), warm water (37c), and boiled liver). If the liver was placed in each of these temperatures, the liver would have a greater rate of reaction when exposed to 37c hydrogen peroxide, as this is the body's natural tempera ture. By examining the chemical reactions produced when the liver was exposed to the hydrogen peroxide, an accurate analysis of the presence of enzymes as well as their reaction rates in each sample may be gained. Methods Part one of this lab was conducted in order to see if the potato or apple had catalase in them. Before the lab was conducted, materials needed to be gathered. We needed 3 test tubes,a test tube rack, a clean stirring rod, 50 mL of hydrogen peroxide in a small clean beaker, forceps, a piece of liver, a slice

Chronology of the Ancestral Anasazi Pueblo People
Chronology of the Ancestral Anasazi Pueblo People The Anasazi (Ancestral Pueblo) chronology was broadly defined in 1927 by southwestern archaeologist Alfred V. Kidder, during one of the Pecos Conferences, the annual conference of southwestern archaeologists. This chronology is still used today, with minor changes within different subregions. Key Takeaways Anasazi has been renamed to Ancestral PuebloLocated in the Four Corners region of the U.S. southwest (intersection of the states of Colorado, Arizona, New Mexico, and Utah)à Heyday between 750 and 1300 CEMajor settlements in Chaco Canyon and Mesa Verdeà Archaeological remains of what archaeologists call the Ancestral Pueblo are found on the southern Colorado Plateau, the northern parts of the Rio Grande Valley and the mountainous Mogollon Rim in Colorado, Arizona, Utah, and New Mexico. A Name Change The term Anasazi is no longer in use by the archaeological community; scholars now call it the Ancestral Pueblo. That was in part at the request of modern pueblo people who are the descendants of the people who populated the American Southwest / Mexican Northwest- the Anasazi did not in any way disappear. In addition, after a hundred years of research, the concept of what was Anasazi had changed. It must be recalled that, like the Maya people, the Ancestral Pueblo people shared a lifestyle, cultural material, economics, and a religious and political system, they were never a unified state. Early Origins Cutaway illustrations of pre-pueblo pithouses, built by the Ancestral Pueblo people of Colorado. Dorling Kindersley / Getty Images People have lived in the Four Corners region for some 10,000 years; the earliest period associated with the beginnings of what would become Ancestral Pueblo is in the late archaic period. Southwestern Late Archaic (1500 BCEââ¬â200 CE): marks the end of the Archaic period (which started at around 5500 BCE). The Late Archaic in the Southwest is when the first appearance of domesticated plants in the American Southwest (Atl Atl Cave, Chaco Canyon)Basketmaker II (200ââ¬â500 CE): People relied more on cultivated plants, such as maize, beans, and squash and began to construct pithouse villages. The end of this period saw the first appearance of pottery.Basketmaker III (500ââ¬â750 CE): more sophisticated pottery, first great kivas are constructed, the introduction of bow and arrow in hunting (Shabikeshchee village, Chaco Canyon) Pithouse to Pueblo Transition Visitors walk through the ruins of a massive stone complex (Pueblo Bonito) at Chaco Culture National Historical Park in Northwestern New Mexico. The communal stone buildings were built between the mid-800s and 1100 AD by Ancient Pueblo Peoples (Anasazi) whose descendants are modern Southwest Indians. Robert Alexander / Archive Photos / Getty Images One important signal of development in Ancestral Pueblo groups occurred when above ground structures were built as residences. Subterranean and semi-subterranean pithouses were still being built, but they were typically used as kivas, meeting places for political and religious events. Pueblo I (750ââ¬â900 CE): residential structures are built above ground, and masonry is added to the adobe constructions. In Chaco Canyon villages are now moving from the cliff tops to the bottom of the canyon. Settlements at Mesa Verde begin as large sedentary villages built into the cliffs with hundreds of residents; but by the 800s, the people living at Mesa Verde apparently leave and move to Chaco Canyon.Early Pueblo II- Bonito phase at Chaco Canyon (900ââ¬â1000): increase in the number of villages. First multi-storied rooms constructed at Pueblo Bonito, Peà ±asco Blanco, and Una Vida in Chaco Canyon. Chaco becomes a socio-political center, where some individuals and groups hold a great deal of power, seen by architecture requiring organized labor, rich and unusual burials, and large scale flows of timber into the canyon.Pueblo II- Classic Bonito phase in Chaco Canyon (1000ââ¬â1150): a period of major development in Chaco Canyon. Great house sites, such as Pueblo Bon ito, Peà ±asco Blanco, Pueblo del Arroyo, Pueblo Alto, Chetro Ketl reach now their final form. Irrigation and road systems are constructed. Decline of Chaco A trail leads visitors to Spruce Tree House ruins in Mesa Verde National Park in Colorado, built between 1211 and 1278 CE. Robert Alexander/Archive Photos/Getty Images Pueblo III (1150ââ¬â1300):Late Bonito phase in Chaco Canyon (1150ââ¬â1220): population decline, no more elaborated constructions in the main centers.Mesa Verde phase in Chaco Canyon (1220ââ¬â1300): Mesa Verde materials are found in Chaco Canyon. This has been interpreted as a period of increased contact between Chacoan and Mesa Verde pueblo groups. By 1300, Chaco Canyon definitely declinedà and then was abandoned.Pueblo IV and Pueblo V (1300ââ¬â1600 and 1600ââ¬âpresent): Chaco Canyon is abandoned, but other Ancestral Pueblo sites continueà ââ¬â¹to be occupied for few centuries. By 1500 Navajo groups entered the region and established themselves until the Spanish takeover. Selected Sources Adler, Michael A. The Prehistoric Pueblo World, A.D. 1150-1350.

Charless Pen and Jesus Name
Charless Pen and Jesus Name Charless Pen and Jesus Name Charless Pen and Jesus Name By Maeve Maddox Commenting on When to Form a Plural with an Apostrophe, Luke S. raised another question: What gripes me . . . is the misuse of the apostrophe to form the possessive without the extra s: Charles pen needs correction to Charless pen. Ah, Luke, would it were so simple as that! Even the Chicago Manual of Style, so authoritative in so many ways, makes this observation on the use of the apostrophe to form the possessive: Since feelings on these matters sometimes run high, users of this manual may wish to modify or add to the exceptions. When I taught in England, the textbook I used gave the rule that ancient names ending in -s took only an apostrophe, while modern names took apostrophe s: Achilles heel, Jesus name, St. Jamess Park. This rule was no doubt derived from Fowler: It was formerly customary, when a word ended in -s to write its possessive with an apostrophe but no additional s, e.g. Mars hill, Venus Bath, Achilles thews. In verse, in poetic or reverential contexts, this custom is retained. ..But elsewhere we now add the s the syllable, Charless Wain, St Jamess not St James, Joness children. . . After many paragraphs setting forth the correct use of using the apostrophe to form various possessives, the CMS offers an alternative: Those uncomfortable with the rules, exceptions, and options outlined above may prefer the system, formerly more common, of simply omitting the possessive s on all words ending in s- hence ââ¬Å"Dylan Thomasââ¬â¢ poetry,â⬠ââ¬Å"Maria Callasââ¬â¢ singing,â⬠and ââ¬Å"that businessââ¬â¢ main concern.â⬠Though easy to apply, that usage disregards pronunciation and thus seems unnatural to many. This apostrophe business is felt to be of such import that there has even been legislation on it: In February 2007 Arkansas historian Parker Westbrook successfully petitioned State Representative Steve Harrelson to settle once and for all that the correct possessive should not be Arkansas but Arkansass. Arkansass Apostrophe Act came into law in March 2007. ABC News [USA], 6 March 2007. Before you start making jokes about the priorities of the Arkansas legislature, know that no less august a body than the Supreme Court wrestled with apostrophe usage in 2006. Justice Thomas opinion was that whenever a singular noun ends in s, an additional s should never be placed after the apostrophe. The dissenting opinion was that an s should always be added after the apostrophe when forming a singular possessive, regardless of whether the nonpossessive form already ends in s.

State judicial system Essay Example | Topics and Well Written Essays - 500 words
State judicial system - Essay Example Jurisdiction is conferred by laws and therefore cannot be waived or subject to agreement by parties. A defendant has the right to appeal a trial courtââ¬â¢s decision, usually once, to the next immediate appellate court. Any other appeal from the initial appeal is discretionary and may be done only through a writ of certiorari or discretionary review. The appellate courts review only the law applied by the lower courts, leaving the findings of facts intact, and no new issues can be considered. They rely solely on the trial briefs of the parties and the records of the proceedings in the trial court. A discretionary review or review via a certiorari is accepted only if the issue at hand is novel or of such general importance. The final resort that a defendant can avail of, after showing state-level exhaustion, is with the federal courts on a petition for a writ of certiorari or petition for a writ of habeas corpus (Acker & Brody 2003 pp 26-29). The lowest court level in the federal court system is the federal district court, of which every state and US territory has at least one. In addition to violation and issues of the US Constitution, federal laws, treaties, diversity of citizenship jurisdiction, these courts have jurisdiction over petitions for habeas corpus that state prisoners may file on the ground that their convictions or sentences violate the US Constitution. Moreover, there must be actual disputes and controversy for federal jurisdiction to apply. On the other hand, the US federal Courts of Appeal can entertain only appeals from federal district courts within their respective circuits as the federal district courts are divided into circuits and assigned an appeals court. Additionally, certain limits of the amounts in dispute are considered before an appeal can be had to the circuit courts. In civil cases, for example, the amount involved must be more than $50 and in admiralty $300. An appeal

Trend article analysis Essay Example | Topics and Well Written Essays - 750 words
Trend article analysis - Essay Example was used because of the advantage of being able to control other variables in the environment in order to get accurate analyses and the fact that research is conducted by experts with adequate number of subjects while controlling competing factors. The methodology addresses two important issues. The first being the manner in which the stressful events could be introduced to children in ways that were salient and personally involving and the second, was the manner in which the features could be conceptualized to make them stressful . Although there have been drawbacks in the traditional methodology of analogue research, improvisations were made in the procedure that made the observations and analyses more accurate for further empirical and statistical deductions in psychology research. A child has to put up with a number of stressful situations, whether at school from peers or at home where he has to contend with intra-parental conflicts or economical challenges. These have led to changes in the way research studies are now conducted in child psychology. According to Daniel Lees in, ââ¬Å"An Empirical investigation of the motivational theory of coping in middle to late childhood.â⬠dealing with problems and annoyances can potentially facilitate development; they present children and youth with opportunities to develop coping skills and strategies, strengthening their resources and confidence for dealing with future events (Losoya et al. 1998;Skinner and Zimmer-Gembeck 2007). According to Cummings 1995, various dimensions of an event can be precisely specified and presented in the same way across all participants and explicit recordings of responses on multiple dimensions (e.g. Cognitive, verbal, emotional and physiological) is possible, in fact simulations or other constructed representations of actual events; live or recorded on videotape or audio tape are presented to members to obtain their reactions, as one form of laboratory method that can assess

Into Thin Air Analysis Essay Example for Free
Into Thin Air Analysis Essay ââ¬Å"Brilliant. Vertiginously excitingâ⬠¦vibrantly imagined. An achievement of extraordinary depth and beauty of the natural world.â⬠ââ¬âRaul Dagmar Into Thin Air is based on a true story seen through the eyes of Jon Krakauer. He is a journalist and mountain climber who decides to climb the treacherous Mount Everest and joins the most disastrous expedition in history. Krakauer mixes in with the climbing service called Adventure Consultants, which is guided by Rob Hall who is also responsible for the lives of ten other climbers. The climb is structured into camps: Base Camp, Camp One, Camp Two, Camp Three and Camp Four. After spending weeks at Base Camp, the group makes a number of trips up to the other camps to speed up the acclimatization process. Throughout the climb to the summit, Krakauer significantly details his teammates, his guides and other expeditions on the mountain. He tries to link together a continuous timeline of the events that take place in the weeks they are on the mountain. Everest is a bare and harsh land. All of the clients have difficulty adjusting to the altitude, tiring easily and losing oxygen. The climbers experience in mountain climbing and at high altitudes variesââ¬âsome of them are qualified while others very inexperienced and highly dependent on the guides. Will they survive? ââ¬Å"â⬠¦[Krakauer] reveals that the human spirit has infinite ability to grow and can never be limited by circumstance. It will change the way you look at the obstacles of your own life and the American Dream.â⬠-Henry David Thoreau
