Free Essays on Italian Culture

. In research on interpersonal distance, body orientation, and touch in correlation with culture, it was found that Italians represent contact cultures. Italian dyads used touch during their interactions more than did the English, French, and Dutch dyads (Remland, Jones, & Brinkman, 1995... Free Essays on Italian Culture Free Essays on Italian Culture History and Demographics: In the United States today, there are currently 26 million Italian-Americans. According to the US Census Bureau, they are the nation’s fifth largest ethnic group. Italian-American’s are mainly middle class republicans living in industrial cities primarily in northeastern states. I chose to study this group because my mother’s side of the family is one hundred percent Italian. I have grown up with certain Italian customs and traditions, so it was interesting for me to research Italian-American families more in depth. In 1850, there were less than 4,000 Italians in America. Between 1876 and 1976 there was mass emigration from Italy to the United States. They were met with hatred and discrimination when first arriving to America mainly because their customs and their strong Catholic religious faith was feared. Physical Characteristics, Last Names, Language: Italian-Americans can be recognized by their physical characteristics as well as their last names. Physical characteristics usually consist of dark hair, dark features, and tan skin. The majority of Italians are shorter than average and have more body hair than average. It is also common that Italians are overweight due to their love of food. Italian last names always end in a vowel such as Fiorda, Trizzino, and Torricelli. The majority of Italian-Americans speak English and have a sense of the Italian language. There are some Italian-American families who still speak Italian in their homes in order to maintain their cultural roots. Italians and Italian-Americans are also recognized for using hand gestures while speaking to emphasize their words. In research on interpersonal distance, body orientation, and touch in correlation with culture, it was found that Italians represent contact cultures. Italian dyads used touch during their interactions more than did the English, French, and Dutch dyads (Remland, Jones, & Brinkman, 1995...

Policy Analysis Essay Example | Topics and Well Written Essays - 1000 words

Policy Analysis - Essay Example The most fundamental obligation of Homeland Security is to secure and protect the American people. It is the duty and policy of Homeland Security to guide the nation as they commit themselves to achieve a more protected Homeland, which can sustain the people’s way of life. George Bush outlined the range of homeland security threat based on the opening recommendations of National Strategy for Homeland Security. The document provided a good example of how to create public policy (Forest, 2006, p.132). The executive branch of government had to inspect and identify the weaknesses and strengths of Homeland Security. The strengths and weaknesses were identified based on prevention, recovery, protection, deterrence and response. After the identification, the formulated policies intensified the emerging problems leading to the creation of the strategy. The influences of such articles are crucial and should be guarded. It is a statement of purpose without the force of law. The strategy of Homeland Security points out to congress to put on more efforts to work together with homeland security. The congress should not depend on Homeland Security; instead, it should take steps to deliver its responsibilities with respect to protection of the American people and the Homeland. The statement has salient points and the powers required in turning policy into law. It also acts as a reminder on how the president’s powers are delivered to the zenith as they are channelled to legislative and executive branches at the same time. It is extremely valuable to look in detail the roles of the three branches of government in addressing homeland security threats like illegal immigration, street gangs, terrorism, gun ownership, and sale of illegal drugs. Global war on terrorism has triggered the acts relating to how the enemy combatants are treated by use of military operations, conducting local intelligence, and military tribunals. The congress passed a resolution as a respons e to the 9/11 attacks and the continued threat and attacks posed by terrorists (Forest, 2006, p.140). The resolution gave the president powers to apply and emphasize his powers as commander in chief. The president authorizes the use of the necessary force against organizations, persons who planned, committed, and aided the attacks, which occurred in 2001. In addition, under the law, the congress authorises and gives its formal and constitutional powers. In this regard, the United States Army plays the role of defending the national security. This is against continuing threats posed by Iraq and other relevant council resolutions. The president played a role in establishing Iraq’s support of national terrorism. The United States has a long history and valued tradition of welcoming visitors without restrictions. The attacks of 2001 made United States be more cautious because they realise that some visitors come to the United States to raise funds for terrorist activities, and co mmit terrorist acts. It is the responsibility of United States to prevent foreigners with the intent of committing the terrorist attacks. In addition, they should deport, detain, and prosecute other aliens with the same intentions but are residing in the country. After 9/11, the attention of United States enforcement and administration of immigration policy increased (Forest, 2006, 148). The legislation regarding enforcement and a

Molecular basis of aging in relation to fertility Essay

Molecular basis of aging in relation to fertility - Essay Example Aging is defined as â€Å"a progressive, time-dependent deterioration of an organism’s capacity to respond to environmental changes, which ultimately makes it susceptible to death† (Allen and Balin 4). It is a widely-accepted idea that aging is a natural process that occurs in all living organisms. Since the process of aging most likely would be affecting an organism’s overall body functions, it would also greatly affect its capacity to reproduce, eventually leading to a decrease or the loss of fertility of the said organism (Liu and Case 1169). At present, there are numerous links between chromosomal and DNA damage not just to the aging process of an organism but also on fertility. A female’s capacity to conceive and give birth, or a male’s capability to contribute in conceiving a child is called fertility (Masoro 161). In order to proliferate the species well into numerous and succeeding generations, organisms must be able to produce as much offsp ring as possible that are able to adapt to the current environment that they live on. For that to happen, the process called natural selection takes place (Torday and Rehan 12). Also, the energy that flows within the organism is appropriated in such a way that during the process of reproduction, most of the energy from the consumption of food is distributed to the body’s reproductive systems, mostly to the rapidly-dividing cells called the gametes. However, once the organism starts the process of aging, the energy being exerted for reproduction is reduced and more focus is given to the maintenance of the organism’s body, especially when there is the presence of a rapid breakdown of cells as well as the decline of cell-to-cell communication within the systems and organs (13). Not only is the production of cells affected by aging, but also the process of DNA replication and repair as well. Due to the proliferation of damaged DNA especially in the sex cells of the organis m, it would eventually contribute to the creation of deformed or dysfunctional oocytes or spermatozoa that would eventually be the cause of the loss of reproductive capability or infertility among aging organisms (Sikka 78). Among pregnant women, the imbalance of antioxidants and pro-oxidants may result to oxidative stress due to reactive oxygen species (ROS), which could affect DNA production when in excess, or affect cell-signaling pathways when deficient (Dupont, Cordier and Junien 25). Also, due to the age-associated decline of female fertility can be attributed to the abnormalities found in the oocytes themselves. Due to the abnormalities in the folding of the DNA and eventually, the abnormalities in the alignment of the chromosomes during meiosis and diakinesis which can be attributed to the mutations in the microtubules, preimplantation of embryos or aneuploidy in the fertilized egg may cause spontaneous abortions among older pregnant females (The Practice Committee of the Am erican Society for Reproductive Medicine (PCASRM) 248). Male fertility is also greatly affected by ROS, wherein the spermatozoa membranes would be highly-susceptible to oxygen damage due to the peroxidation of lipid membranes, damaging the sperm and rendering them incapable of fertilizing the ovum (Sikka 78). Also, the presence of errors in the DNA called nicks could also contribute to male infertility due to loosely-packed DNA and chromatin disorganization (Sakkas, Urner and Bizzaro 11). These nicks may be attributed to age-induced DNA

Self Esteem Essay Example for Free

Self Esteem Essay You cant touch it, but it affects how you feel. You cant see it, but its there when you look at yourself in the mirror. You cant hear it, but its there every time you talk about yourself. What is this important but mysterious thing? Its your self-esteem! Self Esteem is defined as confidence in your own merit as an individual. Our self-esteem is instilled in us during our youth. There are two types of self-esteem. There is high self-esteem which is when you feel good about yourself, and then there is low self-esteem which is when you feel bad about yourself. see more:explain the link between identity self image and self esteem Being constantly criticized by family, friends, and society tends to slowly strip us of our feelings of self-worth. Your self-esteem, however, is something more fundamental than the normal ups and downs associated with situational changes. For people with good self-esteem, normal ups and downs may lead to temporary fluctuations in how they feel about themselves, but only to a limited extent. In contrast, for people with poor self-esteem, these ups and downs drastically impact the way they see themselves. A dynamic relationship exists between self-esteem and skill development. As a child improve in self-esteem, his academic competence increases. And as that competence increases, his self-esteem improves. One of the main factors differentiating humans from other animals is the awareness of self: the ability to form an identity and then attach a value to it. In other words, you have the capacity to define who you are and then decide if you like that identity or not. The problem of self-esteem is this human capacity for judgment. It’s one thing to dislike certain colors, noises, shapes, or sensations. But when you reject parts of yourself, you greatly damage the psycho logical structures that literally keep you alive. Judging and rejecting yourself causes enormous pain. Now-a-days many organizations and the international council on self-esteem serves to promote public and personal awareness of the benefits of a healthy sense of self-esteem and personal responsibility and to establish conditions within families, schools, businesses and governments that foster these qualities. Because self-esteem is a feeling not a skill it can only be measured by observing the way in which a person acts or behaves. However, what we feel about ourselves is not based solely on what we do. It usually involves our relationships with others and whether we feel worthwhile as people. We have a basic human need to be wanted, noticed, and included. Observing ourselves in relation to other people can be a helpful source of learning and feedback. Yet all too often comparison slips into competition. The reality is we are all different. Each of us has strengths and limitation which we need to learn about and learn to live with. Do not assume you are not important; other people have an effect on you and you affect them. It is no good waiting for others or circumstances to leave us feeling better about ourselves. So accept responsibility for your own actions: as we cannot make other people change, we need to make the changes ourselves.

The West African Regional War Essay -- Politics Government Africa War

The West Africa Regional War For observers of the West Africa regional war, the recent calm in the war-torn Mano River Union (MRU) states Liberia, Sierra Leone, and Guinea has given rise to optimism. Guarded, as this optimism might be, the decrease in violence in West Africa during the second half of 2001 is an important development given the scope and intensity of fighting that gripped these states earlier in the year. While observers agree that the current absence of widespread violent conflict in the MRU is a much-welcomed development, it must not mask the profound cleavages within these societies, the tenuous nature of the UN-imposed peace in Sierra Leone, and the continued serious threat of renewed warfare in the region. A brief overview of the horrendous and persistent conflicts that have engulfed the MRU over the past decade underscores the need for vigilance by the international community in its pursuit of lasting peace in West Africa. The past dozen years of violent conflict in West Africa have led to the death, injury, and mutilation of hundreds of thousands of people and the displacement of millions more. Conservative estimates place the total number of war-related deaths during the seven-year civil war in Liberia (1989 1996) at 150,000, more than 5 percent of Liberia's estimated population (SIPRI Yearbook, 1996). But this number only begins to tell the story of the horror that civil war brought to this small nation of 2.8 million [United Nations Development Program (UNDP), Human Development Report, 1995]. Hundreds of thousands more Liberians were injured, displaced, and terrorized by the conflict, and today the tiny state remains the hostage of its corrupt and brutal dictator, Charles Taylor. After the war spread into Sierra Leone in 1991, it had a similarly devastating effect. As in Liberia, armed insurgents preyed on the rural populations, raping, pillaging, and forcefully inducting children into their ranks. During the eight years of warfare that followed, it is estimated (conservatively) that over 60,000 of Sierra Leone's estimated 4.2 million inhabitants were killed and hundreds of thousands more injured, mutilated, and displaced (SIPRI Yearbook, 2001; UNDP, Human Development Report, 1995). The 2001 UNDP Human Development Report ranks Sierra Leone last out of the 162 nations rated on the human development index (HDI), a composite ... ...ll play in the future of the region. 6.  Ã‚  Ã‚  Ã‚  Ã‚  Develop a mid- and long-term regional plan for West Africa that accounts for big-picture economic and human development trends. 7.  Ã‚  Ã‚  Ã‚  Ã‚  Implement the Africa Growth and Opportunity Act as soon as possible and draft and then implement AGOA II, thus extending the number of products covered by the legislation. 8.  Ã‚  Ã‚  Ã‚  Ã‚  Buttress socio-economic development in Nigeria, the most populous and perhaps most important U.S. ally in sub-Saharan Africa. 9.  Ã‚  Ã‚  Ã‚  Ã‚  Cut off financial resources to warlords who gain sustenance from non-state profiteers like diamond and timber buyers as well as from state actors intent on creating instability to further their own political and economic goals. 10.  Ã‚  Ã‚  Ã‚  Ã‚  Continue military assistance to the key regional armies to professionalize them and build linkages with the United States. 11.  Ã‚  Ã‚  Ã‚  Ã‚  Speed up debt forgiveness, especially for those countries that play by the rules and are in the process of socio-economic liberalization. 12.  Ã‚  Ã‚  Ã‚  Ã‚  Increase aid to the region as an investment in stability, socio-economic development, and the creation of new markets for the United States and to help prevent state collapse.

Sordaria Fimicola Crossings Linkage Analysis And Frequency Biology Essay

AbstractionThe intent of this probe is to find the frequence of meiotic divisions analyzed from intercrossed crossings collected from different strains of the fungus Sordaria fimicola. The experiment was conducted to show intercrossed crossings with MI and MII forms of ascospores within the asci. Over the class of seven yearss, the sample of Sordaria was incubated and fused under research lab conditions. In the outer countries of the blocks of agar, hyphae growing from the mutant sunburn strain ( t-g+ ) and wild-type black strain ( t+g+ ) was seeable through the â€Å" X-shaped † and outer rims of the Petri dish. By placing the sums of non-hybrid and intercrossed MI and MII asci, the observation of ascospores within the asci displayed the one possible form of MI, and the four possible forms of MII. The first portion of the laboratory experiment formed a hypothesis foretelling that 8 ascospores would ensue from two phases of Meiosis and one phase of Mitosis. After ciphering the frequence of traversing over, the map distance of the cistron to the kinetochore in the sunburn colored cistron observed was 32 map units, significantly different from the projected void hypothesis and expected 26 map units.IntroductionMany research probes utilize the common fungus Sordaria fimicola as a primary and dependable theoretical account being for exposing genetic sciences due to its house construction and life rhythm. Maping the distance between the tan cistron ( t-g+ ) and the centromere requires careful readying of a amalgamate sample of Sordaria already incorporating intercrossed and non intercrossed agreem ents in the ascus. By mensurating the sums of intercrossed MI ( non-crossover ) asci and MII ( crossing over ) asci, and ciphering the frequence of crossing over, the per centum of Asci may besides be calculated from the rate of crossing overs throughout the experiment. With an apprehension of frequence of crossing over, biological political orientations such as version, mutant, and recombination are expressed to the full within the experiment. The void hypothesis provinces that there will non be a considerable difference between the expected 26 map units and the ascertained map distance from the gathered category informations ( Helms, Kosinski, Cummings, 350 ) . Corporate attempt from each bench to cipher the right sum of asci assigned will surely impact the frequence of computation and rejection or credence of the void hypothesis. Biological development closely relates to the procedure of Sordaria crossing overs. Mendel ‘s Law of Independent Assortment is straight validated through the life rhythm of the fungus. As a member of Ascomycota, Sordaria fimicola patterns â€Å" rigorous sexual reproduction † , and provides the easiest visual image of miosis I, II, and mitotic division found in the ascus ( Volk ) . Some features that display the relaxation of observation prevarication in the Sordaria fimicola construction. Elongated nature of the ascus prevents the imbrication of ascospores. Therefore, carefully ruptured perithecia are justly lined up harmonizing to the production of miosis of sunburn and black spores: doing it comparatively easier to execute with more efficiency in numbering MI and MII forms. With its phenotype about tantamount to its genotype, due to the absence of another dominant allelomorph, the accurate physical traits are examined straight from the familial make-up of Sordaria ( H elms, Kosinski, Cummings, 334 ) . During intercrossed crossing overs in Prophase I, a four forms four haploid karyon, each of which so form two monoploid karyon, taking to a sum of eight ascospores in a individual ascus. Generally, Sordaria is a common fungus for genetic sciences research because of assorted grounds centered on the relaxation in the presentation of Meiosis, observation of construction, and/or behaviour of its life rhythm. Growth of the Sordaria fungus is a important factor and dependent variable carried out throughout the survey. The Ascomycota fungus merely grows under the conditions of break uping flora, doing it available for foods to be absorbed and increase hyphae growing and extension ( â€Å" Meiosis and Recombination in Sordaria Fimicola † ) . The consequences of this survey could lend to a broader cognition of mutant, biodiversity, and segregation. Further applications towards look intoing meiotic and mitotic crossing overs and map distances may shortly suggest new readings of Mendel ‘s Torahs.Materials and MethodsDuring hebdomad one of the experiment, wild -type black ( + ) and mutant sunburn ( T ) civilizations of Sordaria fimicola were obtained and while utilizing sterile technique, placed in a unfertile Petri dish divided into four subdivisions labeled for the two cistron colourss. After a metal spatula was disinfected into 95 % ethyl alcohol, it was heated utilizing a Bunsen burner and cooled for 10 to 15 seconds. While carefully raising the palpebra of the Petri dish somewhat to forestall taint, a block of agar was removed and transferred faced down for mycelium linkage and traversing agar. After re-flaming the spatula and reiterating proper sterile technique, the procedure was repeated with wild type ( + ) black strain and two mutation ( T ) sunburn strains positioned on the Markss of the Petri dish bespeaking the labelled asset ( + ) mark. After all necessary blocks of agar have been placed in the proper subdivisions of the Petri dish, the home bases were incubated in 22 to 24A °C temperature in the dark for 7 yearss. During hebdomad two, a home base of Sordaria fimicola incorporating the merger of black and tan strains were obtained for the analysis of loanblends and non loanblends within the 8 produced ascospores. Using a toothpick, the surface of the home base along the â€Å" X-shaped country † was scraped gently to roll up a sample of perithecia. A slide of perithecia was prepared by dropping H2O on a slide the collected perithecia, and so secured with a coverslip. Before puting the slide under a 10x Objective microscope, the slide was foremost gently pressured with a pencil eraser or tantamount force per unit area arrow tearing the perithecia without destructing the construction of the ascus. Using the microscope, slides were examined to turn up loanblend and non intercrossed asci. Class information on Numberss of MI, MII, Total Asci, per centum of crossing over, and frequence were calculated. A Chi -Square Test was performed since necessary.

I†¡A? = 16.291Expected P & lt ; 0.001, reject void hypothesis because 26 a†° 32 Degree of freedom ( d?’ ) = 1DiscussionBased on the single bench consequences, the figure of entire MI and MII asci counted depended on the figure of asci assigned per individual. For illustration, since there were merely two bench members in Bench B and each bench member in the category were assigned to happen and number 5 intercrossed crossing overs each, accordingly, there was a sum of 10 MI and MII asci for Bench B, shown on the tabular array. Harmonizing to the Biology Lab manual, 26 map units was the published map distance of the sunburn spore cistron from the kinetochore ( Helms 350 ) . The degree of frequence is closely related to how â€Å" slackly † or â€Å" tightly † linked cistrons are on the chromosome. For this experiment, the divergences between the frequences of the benches separately does non look drastic, although the consequences from Bench F shows a rebuff over computation of entire asci counted, hence ensuing with the highest frequence degree of 34.6, manner over the expected 26 map units. Analyzing the category informations as a whole, with 276 entire MI and MII Asci counted, the per centum ( % ) of Asci demoing crossing over was 64 % , giving a frequence of 32 map units. In order to warrant if there is a important difference between the 32 map units observed and the 26 map units expected, we perform a Chi -Square computation. With I†¡A? bing 16.291, my decision is that the category information demonstrates a much higher frequence than expected. The grade of freedom ( d?’ ) for the experiment was 1, from n-1, with 2 properties MI and MII. Since the chance value ( P ) was greater than ( & gt ; ) 0.05, we rejected the void hypothesis and accepted the alternate hypothesis asseverating that our ascertained frequence of 32 map units is significantly different from the expected 26 map units provided by published consequences. Possible Beginnings of mistake can be closely examined from the bench informations consequences. Besides an over computation of MI and MII asci, mentioned earlier that produced inconsistent figures, another beginning of misreckoning may hold come from counting/including intercrossed crossing overs that had a 3-1-2 or 2-3-1 unnatural agreement. Many times pupils were obligated to reconstitute a new slide of perithecia because their slide either did non hold adequate loanblends, or they ruptured the vulnerable perithecia falsely, turn outing really clip devouring. Overall, the conducted lab was precise in ciphering the frequence. Sordaria fimicola probes have multiple intents and applications. If conducted right, the fungus demonstrates an accurate agreement of spores ensuing from the meiotic and mitotic divisions. In a really similar research lab experiment, Meiosis and Recombination in Sordaria Fimicola, the same attacks of the two labs shared common processs including: traversing a wild type and mutant type cistron, turning the hyphae in decomposing flora, and ciphering the familial map distances. Calculating the figure of map units will be consistent throughout most Sordaria fimicola surveies because the frequence of traversing over is ever divided by 2 ( because frequence of recombination is precisely.5 of frequence crossed over ) proved in most probes. The relaxation of turning agar on Petri dishes and traversing a wild type and mutant cistron additions recombination of familial stuff, taking to additions in the scope of genotypes, paving a manner towards future additions in biological development.Menti onsHelms, Doris R. , Carl W.
