Borderline Personality Disorder ( Ptsd ) - 864 Words

Mental illnesses are a taboo to talk about, especially when it is one that is known for being missed diagnosed. Borderline personality disorder (BPD) is defined as â€Å"a serious mental illness marked by unable moods, behavior, and relationships† (MD p. 1). Most people have no idea what BPD is because only â€Å"about 1.6 percent of adults in the United States have borderline personality disorder in a given year† and it does not get the acknowledgement that it should, because of misdiagnosis (MD p. 1). Depression, anxiety disorder, eating disorders, substance abuse, and/or antisocial personality disorder are other illnesses that co-exist with BPD. With the overlapping of different illnesses it makes it difficult to get a proper diagnosis, which can make the situation worse for the person that is suffering. Different people that have this disorder have different experiences with it. Alice is a girl has both BPD and posttraumatic stress disorder (PTSD). She made a blog t o tell about what it is like with BPD called â€Å"What having borderline personality disorder really means†. Since the disorder means different things to different people Alice defines BPD as â€Å"Having BPD means I struggle a lot with my own identity, with my unstable and often overflowing and ever-changing emotions, with relationships, with basic functioning, and very often with self-harm† (Alice paragraph 4).

Benjamin Farhi 5/1/13 Band D East to West Frederick Turner Jackson, born in 1861, in Portage, Wisconsin, grew up in a time of severe social change, in a nation plagued with an identity crisis. Fascinated by the world around him, Turner chose to become a history professor, devoting his entire life to studying American culture/society while teaching at the University of Wisconsin and Harvard. Constantly having the opportunity to study and observe the development of the â€Å"American†, Turner wrote extensively, about which attributes composed and influenced American democracy, societal values, and image.

Correlated with Westward Expansion followed the advancement of democracy. The increase of West Coasters although on opposite sides of the Country led to a rise of patriotic sentiments according to Turner. As he says in, â€Å"The Significance of the Frontier in American History†, American democracy was born of no theorists dream†¦ It came out of the American forest, and it gained new strength each time it touched a new frontier. † Turner felt that the each newly empowered settler who discovered success on the West Coast was fulfilling the American Dream. And by doing so, each one of these citizens was helping progress American democracy, as a system that aided the people in creating a more perfect union, even in the shadow of significant social challenges. Turner’s emphasis on the Frontier shaping American character through adaptation had strong undercurrents of sectionalism. He wrote, â€Å"The Significance of the Frontier in American History,† in opposition to the Census Bureau’s report of 1890 and did not believe the federal government should dictate what was and was not a frontier.

Internet Essay Example For Students

Internet Essay Emanuel HALAPCIUCRuxandra ICAInternet-ul si (r)evolutia comunicatiilorFac. Management, anul II, gr.126Cuprins: ? Internetul aparitie, scurt istoric? E-business, afacerea sec. 21? Nevoia de viteza si noile tehnologii de comunicatie? Mobilitate maxima: cu Internetul la plimbare? Tendinte pentru viitorul apropiat? Bibliografie Acum 4 decenii se lansa cu mare pompa primul satelit de comunicatii, Echo 1. La acea vreme, evenimentul capta atentia intregii lumi. Azi, lansarea unui satelit e ceva banal. Anul trecut, IRIDIUM (reteaua globala de telefonie mobila) declara ca mai are de lansat doar citiva sateliti, pentru a fi operationala in orice punct de la suprafata Terrei. Un exemplu sugestiv despre cum a evoluat societatea informationala Si totusi, lansarea lui Echo 1 este un eveniment exceptional. Pentru ca a deschis un nou univers: transmiterea aproape instantanee a informatiei din orice punct de pe glob, in orice punct de pe glob. Practic a redefinit conceptul de comunicatii. Si din 1960 incoace, acest concept se modifica de la o zi la alta. Ceeea ce ieri era idee revolutionara, miine va fi deja demodat. Permanent se impun noi standarde, in care cuvintele cheie sunt:mai rapid, mai eficient, mai ieftin. Si principalul respnsabil este INTERNET-ul. Internetul aparitie, scurt istoricEmbrionul Internetului se numeste ARPANET, si a aparut in 1969. A fost creat de ARPA(initialele vin de la Advanced Research Project Agency), faimosul proiect al Departamentului de Aparare al SUA. Scopul sau era pastrarea controlului asupra armelor atomice in cazul unui atac nuclear. ARPANET-ul a fost conceput initial ca o retea la nivel restrins, intre centrele de cercetare academice, industriale sau guvernamentale. Primele noduri ale retelei au fost Stanford Research Institute, Ucla, UC-Santa Barbara si Utah University. Oamenii de stiinta au realizat insa potentialul urias pe care-l avea acest sistem de transmitere a datelor in dezvoltarea industriei comunicatiilor. Intr-adevar, treizeci d e ani mai tirziu de la inventarea primei masini electronice de calcul, reteaua mondiala de calculatoare interconectate cuprindea deja peste o suta de mii de computere. Si numarul acestora creste zi de zi, intr-un ritm exponential. Pentru a se ajunge insa la asemenea performante, Internetul a suferit o serie de modificari, menite sa-l faca cit mai accesibil unui numar cit mai mare de utilizatori. Merita aici mentionata dezvoltarea primului program WWW(initialele de la worldwide web), in anul 1990, care stabilea o orientare grafica pentru retele. Un an mai tirziu, fisierele worlwide web devin accesibile pe Internet. Tot in 1990, apare primul sistem de cautare a fisierelor pe Internet, numit Archie. Odata cu aparitia www, asistam la un adevarat boom al Internetului. Noua interfata grafica permite practic oricui stie sa citeasca acces la un urias volum de informatie. Astfel ca, in 1992 numarul conectate la Internet depaseste un milion. De asemenea, pentru facilitarea manevrarii datelor, au aparut pe parcurs o serie de protocoluri si standarde de transmisie a datelor. Astfel, in 1971 se stabilesc standardele pentru doua tipuri de procese fundamentale: Telnet, pentru conectarea mai multor calculatoare la retea, si FTP(file transfer protocol), pentru transferul de fisiere intre calculatoare. In 1979, se infiinteaza Usenet, primul sistem de transmitere a informatiilor pe retea intre diferite grupuri de lucru. Nu in ultimul rind, trebuie mentionata suita de protocoale Transmission Control Protocol si Internet Protocol, cunoscuta azi ca standardul TCP/IP. Si zi de zi, apar noi si noi standarde, care fac din Internet un instrument mai atractiv si usor de utilizat. Practic asta a fost se cretul succesului. E-business, afacerea sec. 21Prima forma de comunicare pe Internet, intre 2 utilizatori, a fost e-mail-ul. Desi pentru multi pare o gaselnita recenta, e-mail-ul are venerabila virsta de 28 de ani. Fata de posta clasica, succesul e-mail-ului se datoreaza faptului ca nu trebuie sa te deplasezi pina la posta ca sa-l expediezi. Si ajunge aproape instantaneu la destinatie.posta electronica este astazi un mijloc zilnic de comunicare in afaceri, permitind ca datele si mesajele sa fie transmise instantaneu clientilor, furnizorilor etc. Insa asta a fost numai inceputul. Conceptul de e-business a redefinit modul de a face afaceri. Unul din pionierii e-biz-ului a fost Jeff Bezos. Fondatorul Amazon-ului, cel mai mare magazin on-line din lume, a profitat de faptul ca in anii 1992-94, Internetul cunostea un ritm de dezvoltare de circa 300% pe an. Initial deschis intr-un depozit, astazi Amazon.com este cunoscut oricarui aproape web-surfer. Secretul succesului? Faptul ca iti poti face cumparaturile de acasa, folosind cartea de credit, ca nu ai parte de vinzatori care sa te bata la cap, ca poti cumpara la orice ora din zi si din noapte, ca poti alege orice produs, mai ieftin ca la orice magazin sau supermarket. Pe cine n-ar tenta? Raspunsul ti-l poate da oricare din zecile de mii de oameni care cumpara zilnic de la Amazon. Astazi Bezos este unul dintre cei mai bogati oameni din lume. O performanta realizata in numai 4-5 ani. Si nu putini sunt cei care I-au urmat modelul. Astazi firme de renume ca Ford Motors, General Electr ic, Nike, si lista ar putea continua la nesfirsit, au magazine online. Rezultatele nu s-au lasat asteptate: crestei ale vinzarilor cu 20-30%. Mai mult, Ford si Toyota au promovat concepte de genulautomobilul in trei zile, prin care clientul primeste in cel mult 72 de ore masina pe care o doreste, de la dealer-ul cel mai apropiat. Pe deasupra, cu numai citeva click-uri de mouse, iti poti alege culoarea, echipamentele optionale, instalatia audio pe care o doresti etc. In prezent, un magazin online nu mai este un lux, e o necesitate. Concurenta e necrutatoare. Sintagma e-business or out of business e mai valabila ca oricind. Internetul este cu siguranta afacerea secolului 21. Furnizorii de servicii Internet inregistreaza cel mai mare suuces. AmericaOnLine, unul din primii ISP(Internet service provider), si cel mai mare ca numar de clienti, se situeaza astazi in topul firmelor americane. E de ajuns sa mentionam ca la inceputul acestui an, in luna februarie, AOL a preluat colosul mediati c TimeWarner, contra sumei de 195 miliarde USD. O firma infiintata de numai 5 ani a reusit sa preia un gigant ce dateaza din anul 1920. AOL este exemplul perfect pentru american dream: o firma infiintata intr-un garaj, de 2 tineri cu putini bani dar cu idei, reuseste sa atinga o cifra de afaceri anuala de cateva miliarde de dolari. Si am putea continua cu portalurile Yahoo, Altavista, Prodigy, Lycos etc. Firmele Internet-related fac legea pe pietele bursiere din intreaga lume. Anul acesta, scaderea pretului la actiunile Microsoft, cu 15,37 USD intr-o singura zi(30 martie 2000), a declansat un adevarat seism pe Nasdaq. Bursa nord-americana a inregistrat cea mai mare pierdere din istoria sa, de 349,15 puncte. O alta afacere de proportii ce are ca suport de desfasurare Internetul este e-banking-ul. De ce sa te mai duci pina la banca, sa stai la cozi interminabile si sa pierzi o groaza de timp pentru a depune sau retrage bani, cand o poti face comod, de acasa. Banca iti ofera la orice o ra din zi si din noapte situatia contului tau, iti poate sugera cele mai avantajoase posibiltitati de-a-ti plasa banii, sau ce suma maxima poti sa scoti din cont. Si asta pe gratis, si fara sa depinzi de amabilitatea unei casierite plictisite. Nimic mai simpluIn acelasi mod, poti fi un jucator redutabil la bursa fara sa fie nevoie sa iesi din casa. Poti cumpara sau vinde actiuni instalat comod in fotoliul tau de-acasa. Si pe orice piata bursiera din lume care permite tranzactii online. Si numarul celor care inca nu o fac este din ce in ce mai mic. Pentru ca oriunde e vorba de afaceri, Internetul face legea. Iti ofera viteza si mobilitate, restul depinde de tineNevoia de viteza si noile tehnologii de comunicatieUn element vital in modul in care va evolua afacerea ta online este aspectul magazinului tau. Pagina de web este vitrina magazinului, e cartea de vizita. Oricit ar fi de competitive ar fi produsele si/sau serviciile, nu le poti vinde daca nu exista clienti. Si singurul mod de a-ti atrage clientii este o interfata prietenoasa, atragatoare. Toate acestea inseamna insa sunete, animatii si alte aplicatii multimedia, ce au rolul de a atrage, de a face potentialul client sa-ti viziteze magazinul. Multimedia inseamna insa volum mare de informatie care trebuie sa se incarce la fiecare accesare a site-ului, ceea ce se traduce printr-un timp mare de asteptare. Apare astfel riscul ca potentialul cumparator sa se plictiseasca sa astepte, si sa incerce la alte magazine, care-I vor consuma mai putin timp si nervi. Dar daca scopul site-ului este tocmai promovarea de aplicatii multimedia, ca in cazul unei companii de film, care-ti prezinta tralier-e ale celor mai recente filme, sau al unei formatii muzicale, care, pentru a stirni interesul, in mod obligatoriu trebuie sa contina imagini si sunete? In plus, clientul tau trebuie sa vada ce cumpara. O fotografie a produsului pe care-l vinzi trebuie sa existe, chiar daca ea este de dimensiunea unui timbru. Cu prea putina inf ormatie, nu atragi clientii. Cu prea multa, ii alungi. O solutie ar fi atunci cresterea vitezei de transfer a informatiei. Viteza e cuvintul cheie in Internet. Internetul este eficient atita timp cit iti permite transfer al datelor la viteza mare, si cu distorsiuni cit mai mici. Altminteri cauti alte servicii, mai eficiente. De la lansarea lui Echo 1 in 1960, suprematia in comunicatii au detinut-o comunicatiile via satelit. Problema au constituit-o in schimb terminalele. Nu oricine isi permite o antena parabolica pentru emisia/receptia de la si inspre satelit. Problema s-a pus deci in sensul ca un grup cit mai mare de beneficiari sa aiba acces cit mai rapid la o singura antena. Si daca toata lumea este de acord ca cele mai eficienta cale de transmisie a datelor este transmisia prin satelit, problema vitezei apare la bucla finala, cum este denumita conexiunea de la centrala(ISP) la utilizatorul propriuzis. S-au dezvoltat in acest sens o serie de noi tehnologii. Unele au incercat sa i mbunatateasca reteaua deja existenta, altele au preferat orientarea spre modalitati noi de transmitere a datelor. Reteaua clasica o constituie chiar reteaua de telefonie fixa, care are avantajul unui cost redus de intretinere, in conditiile unei viteze rezonabile de transmisie. Sau asta cel putin pina acum citiva ani. Astazi modemul calsic nu mai satisface pretentiile din ce in ce mai mari ale consumatorilor de web. Prin constructie, linia telefonica nu suporta in mod normal mai mult de 56 kilobytes pe secunda. Insa si aceasta valoare este aproape imposibil de atins, datorita faptului ca pe o linie telefonica nu exista un singur utilizator, ci mai multi. O prima solutie, putin mai scumpa dar mai rapida a fost ISDN(integrated solutions for digital networking), care permite viteze de pina la 128 kb/sec. Serviciul combina serviciile de transmisie de voce si date prin aceeasi pereche de fire telefonice, astfel incit computerele se pot conecta direct la reteaua telefonica, fara a-si conv erti in prealabil semnalul in semnal audio analog. Aceasta integrare ofera o gama larga de posibilitati, care includ transmisii de voce, date, fax si switching. Cel mai important aspect pentru utilizatorii de ISDN este acela ca ofera o imbunatatire semnificativa a vitezei de acces, cu o crestere relativ minora de cost. In plus, pentru ca ISDN utilizeaza reteaua telefonica existenta, aceasta tehnologie este disponibila atit pentru firme, cit si pentru utilizatori individuali. Italian Renaissance Arts Affect On Persuasive EssayO alta tendinta in evolutia Internetului este mobilitatea maxima. Accesul la retea in orice punct de pe glob devine o necesitate pentru tot mai multi oameni. Internetul la purtator este un concept care reinventeaza telefonia celulara. Primii pasi in acest sens au fost laptop-urile, care impreuna cu un telefon mobil permiteau o conexiune Internet decenta. Un urmator pas a fost aparitia hand-heldurilor PDA (Personal Digital Assistants). Aceste dispozitive sunt un inlocuitor de succes al laptop-urilor si notebook-urilor, avind avantajul dimensiunilor mult mai reduse. Un PDA cu un minimodem incorporat si un telefon celular, iata primul model al Internetului de buzunar. Exista si PDA-uri mai avansate, care nu mai necesita nici macar telefonul mobil. Un exemplu in acest sens il constituie device-ul Palm VII, lansat cu un urias succes acum un an in SUA. Acesta dispune de un modem incorporat si un minibrowser care permit conectarea nonstop la Internet, contra unui abonament lunar (9 USD/luna). Din pacate, serviciul este disponibil numai pe continentul nord-american, extinderea lui la nivel global fiind considerata inca prea scumpa de catre Palm, compania care a lansat acest serviciu. O alternativa mai ieftina, care prinde din ce in ce mai mult teren, pare a ramine astfel reteaua de telefonie GSM. Ideea a fost implementarea browser-ului Internet direct in telefonul mobil. Se elimina astfel necesitatea laptop-ului sau a PDA-ului, ceea ce reduce costurile. Un browser este un client software proiectat sa permita accesul unui dispozitiv la servicii Internet, in combinatie cu un server de retea adecvat. Apare aici insa o problema. Popularele standarde de Internet HTML, HTTP, TLS si TCP sunt ineficiente si greoaie cind sunt folosite in retele mobile, intrucit presupun transmiterea unei mari cantitati de text. Continutul standard al unei pagini de Web HTML nu poate fi afisat eficient pe ecranele minuscule ale telefoanelor mobile sau pagerelor, iar navigarea intre mai multe ecrane este foarte dificila. HTTP si TCP nu sunt optimizate pentru intreruperile generate de iesirea unui utilizator de GSM din cimpul de acoperire sau pentru largimea de banda foarte limitata. Exista servicii fara fir care folosesc totusi protocoalele Internet clasice, insa aceste servicii sunt in general scumpe, lente si greu de folosit. Standardul de securitate TLS(Transport Layer Security) presupune un schimb intens de date intre client si server, ceea ce, in conditiile comunicatiilor mobile, se traduce printr-un raspuns foarte lent pentru utilizator. Solutia pentru toate aceste probleme este un nou protocol, de dicat comunicatiilor mobile: WAP(Wireless Application Protocol). Avantajul WAP este ca poate fi folosit in diverse tipuri de retele fara fir, si nu numai pentru GSM. Mai mult, include un mediu pentru aplicatii programate in WML(Wireless Markup Language), compatibil cu orice sistem de operare existent, de la Palm OS, la EPOC, Windows CE, FLEX- OS, OS/9, Java OS, etc. In termeni simpli, srandardul WAP este alcatuit din doua elemente: un mediu si un protocol de aplicatii. Mediul de aplicatii consta din WML, descris mai sus, si bazat pe XML(eXtended Markup Language) care permite programatorilor sa defineasca interfata cu utilizatorul independent de dispozititvul care o va afisa, si un limbaj de programare, WML-script, care permite inglobarea logicii executabile in aplicatiile proiectate. Modelul de protocol WAP este similar cu cel WWW. Acest lucru prezinta multe avantaje in comunitatea dezvoltatorilor de aplicatii, incluzind un model de programare si o arhitectura similare. Evident, pentru a se putea incadra in caracteristicile mediului wireless, WAP a trebuit sa fie modificat si adaptat. Intr-o retea tipica WAP, clientul comunica cu doua servere. Adresa de proxy translateaza apelul WAP in apel WWW, permitind astfel clientului sa trimita apelul la serverul web. Daca serverul raspunde direct cu o informatie de tip WAP(de exemplu in format WML), proxy-ul preia informatia direct de la server. Totusi, daca informatia este trimisa in continut WWW, (de exemplu in format HTML), atunci se va utiliza un filtru pentru a translata informatia in WML, sau in alt format recunoscut de WAP. Utilitarele de WAP sunt interactive si bazate pe un sistem de meniuri. Exista terminale care suporta grafica, icon-uri, seturi de fonturi, iar tendinta este de a asigura un ecran cit mai cuprinzator pentru telefonul celular WAP-ready. Telefoanele de ultima generatie pot fi programate manual, folosind meniul aparatului. In viitorul apropiat, acest proces va putea fi simplificat considerabil prin trimiterea unui mesaj SMS, iar setarile vor fi ajustate automat. In acest domeniu, virful de lance il reprezinta colosii telefoniei mobile clasice: Nokia, Motorola si Ericsson. Motorola a lansat recent modelul Timeport, care pe linga cardul SIM mai poate citi si cardul bancar. Avem astfel de-a face cu primul telefon WAP-able cu care putem face cumparaturi pe Internet. Ericsson a ajuns deja la al treilea produs de acest gen. Nokia a lansat deja o suita de aplicatii WAP proprii, care se bucura de un real succes: serviciul de cotatii online, serviciul de stiri realizat in colaborare cu CNN, etc. Tendinte pentru viitorul apropiatPentru urmatoarele luni, se prefigureaza o adevarata explozie a comunicatiilor fara fir. In intreaga lume, ritmul de crestere a numarului de utilizatori de telefonie mobila este, in medie, de circa 1000% pe an. Iar WAP se prefigureaza a fi noul standard in telefonia mobila. Iridium, reteaua globala de telefonie prin satelit, se extinde rapid. Chiar daca momentan tehnologia este mai scumpa decit GSM-ul uzual, avantajele sale sunt indiscutabile: viteza mare de transfer, acoperire la nivel planetar, suport pentru WAP. Iar costurile vor scadea odata cu cresterea numarului abonatilor. Integrarea comunicatiilor la nivel planetar prin Internet este cuvintul de ordine in ITC.

Salem Witch Trials Essays (2386 words) - Witchcraft,

Salem Witch Trials The Salem Witch trials started in 1692 resulted in 19 executions and 150 accusations of witchcraft. This is one of the historical events almost everyone has heard of. It is a topic that is talked about, and can be seen as controversial. A quote by Laurie Carlson shows just how controversial the topic can be. (A) character myth is certainly what the witch hunts in Europe and Salem have become, though they have more basis in fact than most myths. The stories of the witch hunts are character myths for our time, to be told by feminists, left-wing intellectuals, and lawyers for President Clinton, each taking what he or she needs from the story, adding or subtracting as it seems fit. (1). The trials began because three young girls, Betty Parris, Abigail Williams, and Ann Putnam began having hysterical fits after being caught engaging in forbidden fortune telling. That's right fortune telling, not dancing naked in the woods like the story has been told to many times (2). The fortune telling occurred because they were trying to find out what type of men they were going to marry. Betty Parris' father was a reverend of the town on Salem, Massachusetts. The Reverend, Samuel Parris called in senior authorities to determine if the girls' affliction was caused by witchcraft. Although Betty was sent away fairly soon, and did not participate in the trials, the remaining two girls were joined by other young and old women in staging public demonstrations of their affliction when in the presence of accused witches. The events in Salem have been used as a theme in many literary works. Anthropologists also take interest in these writings because they display some of the characteristics of village witchcraft as well as some of the features of the European witch craze. Many commentators have seen the Salem witch craze as the last outbreak of the European witch craze which was transported to North America. As in African and new Guinea villages, the original accusations in Salem were made against people who the accusers had reason to resent or fear. Moreover, the first few of the accused fit the definition of marginal persons likely to arouse suspicion. However, as in Europe, the accusations spread, and soon encompassed people not involved in any of Salem's grudges or problems. As in Europe, there was a belief that the accused were in league with the devil. Supposed experts went out to do scientific studies to diagnose witchcraft. Interestingly, during the colonial period in Africa, just after WWII, there was a number of witch finding movements in Africa that closely resembled the Salem episode. Typically in these witch finding movements, the witch finders would come in from outside a village and claim to be able to rid the village of all of it's witchcraft. At this period there was great dislocation, with people moving around because of government employment, suitable farmland, and many other causes. Some people were improving their economic status as a result of these change, and others ended up being worse off. Whereas in the past, everyone in a location had followed the same religion, people were now exposed to Christianity and the local religions of people who had moved to their region, or whose regions they had moved to. In the cities of central and Southern Africa, many local religions and Christian sects could be found, as well as Islam. Belief in witchcraft tended to unite people across religious differences. Frenzies increased throughout time, people began to be accused who had not aroused any particular jealousies, possibly because they possessed a peculiar looking item which might be said to contain magical medicine. These crazes tended to die down, at least after considerable conflict and property damage, and the witch finders would then move on to the next town. As witchcraft accusations still occurred in the areas, we can conclude that the movements did not get rid of witches forever. Witch Trials 4 There have been three basic approaches taken to the analysis of the Salem witch trials. Scholars have sought psychological and biological explanations for the symptoms displayed by the bewitched girls. Sexual repression in Puritan New England, the low status of

PsychoSocial Development Theory in Movie Essay

PsychoSocial Development Theory in Movie Essay Eriksons Psychosocial Development Theory Essay Eriksons Psychosocial Development Theory Essay The development of human beings does not only revolve around biological factors but also psychological and social factors (â€Å"Erikson’s Psychosocial Development Theory†, n.d.). The challenges that people face and the intervention measure that they may choose to employ, usually bear resemblance in terms of the people’s biological, psychological and social position (McLaren, 2002). That is to say that, for instance, a human, biological disorder could be the main cause of an individual’s disturbing, psychological condition. For example, a person whose forehead has a deformity may leave with discomfort and dire emotional pain, as a result of that. This situation may inhibit the individual to participate effectively in beneficial activities of within their immediate surroundings, ultimately interfering with their social well-being. Using Jim Sheridan’s movie, In America, this paper seeks to investigate how human beings; functioning hinges on biologica l, psychological and social factors as it is in the Bio-psychosocial-Social Development model, using the individual life experiences of the characters. It is noteworthy that a critical investigation of a personal issue will always yield multiple factors as causes and diverse implications of psychological, biological and social aspects. For instance, disability may be a cause for one’s poor living conditions since they are not in a position to fend for themselves adequately. Consequently, such individuals would lack social recognition in their society, diminishing their chances of self-esteem. Disability, which is a biological issue, leads to poverty-a social problem. Poverty, ultimately, deprives an individual of human dignity and self-esteem which are psychological conditions to any normal human being. Essentially, the PsychoSocial theory is an approach which posits that psychological, biological and social play a significant role in the normal functioning of humans in the context of illnesses (Halligan Aylward, 2006). Movie Overview In the year 1982, a family of Sarah and Johnny Sullivan, together with two daughters-Ariel and Christy, enter the United States of America through Canada. Still feeling the pain of losing their young son Frankie, the bereaved members find their dwelling in unbearable conditions, in the city of New York. They managed to obtain their only shelter, a dilapidated kitchen apartment that accommodates even transvestites, drug addicts and an ascetic Nigerian photographer/artist, Mateo Kuamey (Scott, 2006). The desperate situation affecting the family has waned Johnny’s faith, in spite of his position as a devoted catholic faithful. His relationship with the family has deteriorated while they struggle painfully to make ends meet. In spite of their distress, the pleasure of entering the United States and the unity of the family serves as their motivation to face each day with courage and determination. To hold their cherished moments, Christy uses her valued camcorder. Sarah works in a local ice-cream parlour while Johnny, after numerous auditions, lands the job as a cab driver, in their quest to make a living and support their daughters’ pursuit of education at the Catholic School. The rising temperatures in the area and the diminishing level of their financial ability raise the tension between her and Johnny.   The discovery of Sarah’s pregnancy complicates matters, adding to the already existing emotional strain of the family (Scott, 2006). As they struggle with the life, they get acquainted with Mateo Kuamey who ends up becoming their friend, despite his deteriorated, health condition. The Nigerian photographer/artist has the dreadful AIDS condition. In the end, the death of Mateo and the b irth of the baby marks Johnny’s end of his emotions over Frankie’s demise. The movie comes to an end at the baby shower at the Sullivan family’s apartment with the apartment’s tenants as Christy and Ariel look for Mateo in the sky. Facing Bio-Psycho-Social Challenges Social problems and psychological problems are prominent, throughout the movie, In America. Among the outstanding social challenges that individuals face include poverty, drug and substance abuse, unemployment and lack of adequate education. As a result of these issues, people have to deal with other challenges, which are direct or indirect outcomes of the former. They include a number of psychological tests, which include emotional strain, tension, anger, intolerance and despair. In addition, there are conditions of the body which may pose serious dangers on the body. Such problems may include normal illnesses, deformities on different body organs and abnormal body formation which appear at childbirth. All these problems are interrelated and require appropriate measures of intervention. In accordance with the Bio-Psycho-Social Model of health, with a basis on the social cognitive theory, the treatment of diseases needs to consider factors of psychological, biological and social factors (Sarno, 1998). Thus, in handling tragic incidents of disease, which may sometimes lead to death, people need to find the individual’s connection with other factors within their immediate environment so that not only one side of the coin receives all the attention while the one gets none. It is crucial to bear in mind the concept of body-mind dualism, which posits that, the two, body and mind, work as interconnected elements (Sarno, 1998). That is to say that the body functionality reflects what could be the state of the mind, and functionality of the mind also relies heavily on the state of the body. Although Mateo had the condition of AIDS, his accelerated death may be a result of multiple factors, as opposed to his supposed killer disease. Although he stayed under medication, the Nigerian man suffered from numerous challenges. When he falls off the stairs, Christy attempts to assist him by resuscitating the feeble man. The other residents who know his positive HIV status warn her away. That is a clear indication of stigma in the society for people living with such conditions. The fact that the man spends sleepless nights is an apparent sign of his psychological torture as a result of that stigma. He has money in the trust fund, but nobody knows about this until after his death, when the Sullivan family discovers that he had paid the medical bills for their newborn baby. Besides, Sarah struggles with her pregnancy but eventually gives birth to a child, prematurely. That is abnormal, an indication of her ailing body. From the story of her family, it is evident that the Sullivan family has gone through thick and thin for sustenance, in New York. In addition, they entered the new land with the trauma of losing their young son, Frankie. With this in mind, it becomes certain that the cause of her premature childbirth is multi-factorial. First, she physically strained to make a living from working at the local ice cream parlour. Secondly, she lived with tension between him and his husband, Johnny, because of the severing, relationship. She had the responsibility of ensuring a motherly upbringing of her two daughters, Christy and Ariel Sullivan. In addressing her unfortunate circumstance, the Bio-Psycho-Social Development approach would consider all those factors in a way of finding appropriate treatment options for her. Johnny appears to be a nasty character, from the beginning to the end of the film. His unmistakable problem is of a psychiatric nature. Although his unattractive, social status emanates from the sudden death of his young son at such a tender age, there are other significant factors which can help explain his frustration and anger. He is a father who needs to take good care of his family. He has to find a way of solving his problem of poverty in his family; he has to find a way of paying tuition fees to keep her two daughters in school. However, he lives in New York, poverty-stricken and spends a substantial period searching for jobs unsuccessfully. He never went to a doctor to rediscover himself, eventually. He did so after the death of Mateo and the birth of his child. The two daughters of Johnny and Sarah Sullivan also face challenges of psychological and social complications in their life, both at home and school. Their home languishes in poverty. This makes their living experience a living misery. Besides, their attendance in school is not a smooth ride because of difficulty for their parents to obtain school fees. Expectedly, their performance cannot be up to the mark because of their emotional discomfort resulting from their impoverished lives. Charity, being the oldest child, seems to have accepted the scircumstances as they are, and always tries to find useful activities to do in order to get rid of the disturbing emotions. She uses her camcorder to capture the events of their experiences for reminiscence. For the two daughters, poverty has had a considerable impact on their social welfare, diminishing their social status and confidence as they strive through school, thereby hampering their academic excellence. The outcome is utmost psycholo gical trauma. In the movie, In America, it there is veracity of the Bio-Psycho-Social development approach in human functioning. There is no single factor which characterizes the existence of a challenge on a human’s functional capability. It is true that biological, psychological and social factors influence human development. Hence they affect human function in a connected manner. A fundamental observation also reveals that a person’s challenge, whether psychological, biological or social, may have serious influence upon the lives of others. As a result of Mateo’s HIV status, there is a considerable concern by the whole community. His condition seems to have an impact on the people around him. For instance, there is a fear among many individuals who consider him a risk person to get in contact since he could   infect one with the HIV. This is evident at the time of his falling on the staircase. Christy takes the initiative of resuscitating the ailing man despite the uneasiness and worry among the people around, knowing that he is HIV-positive. On the side of Christy, the man’s condition is a cause for deep concern and empathy, compelling her to risk her own life to offer help. This is a vivid show of psychological challenge that may result from another human’s physical or biological disorder. On the other hand, when Sarah gives birth prematurely, the baby’s health condition becomes everyone’s concern. The father, Johnny gets down to serious business of finding ways of discharging his responsibilities as a father. Although the issue of bearing the child’s medical expenses causes the family a lot of emotional distress, the situation calms down when they discover that the late Mateo had generously catered for them before his death. That brings peace of mind in the family, resulting to Johnny’s change of emotion for a long time, becoming lively and a social man of the family. He put his past behind. He even managed to land a role in the Chorus Line in Broadways. Conclusion Challenges that affect the normal functioning of humans usually bear psychological, biological and social aspects, in their provenance and ultimate impact (McLaren, 2002). In America, the experiences of different characters, more so the members of the Sullivan family and Mateo Kuamey, reflect the inevitable interconnection among the psychological, social and biological factors in the functioning of a normal human being (Gatchel Oordt, 2003). This resembles the mind-body dualism concept which supposes that the state of the mind significantly affects the functioning of the body. Similarly, the state of the body at any given moment affects the thoughts and emotions of a human (Sarno, 1998). The Sullivan family’s experience brings out the true picture of Bio-Psycho-Social development among humans.

Genes Assignment Example | Topics and Well Written Essays - 500 words

Genes - Assignment Example This alteration can be in the form of addition of new pairs, deletion or inversion of a section of the strand. Mutation results to alteration of the stored information in a gene. DNA is a polymer made up of nucleotides. Each of the monomer nucleotides consists of a 5-carbon deoxyribose, a nitrogen base and a phosphate group. The nucleotides are two purines (adenine and guanine) and two pyrimidine (cytosine and thymine). They differ in their nitrogen base. The DNA molecule a pair of polynucleotide strands held together by weak thermodynamic forces that connect the nucleotides from each of the strands making up a pair. The forces connecting the strand between alternating pairs vary making the pair coil around each other forming a helical structure. 3. Define the concept of â€Å"Central Dogma† in biology, and the concepts of transcription, translation, codon, and the redundancy nature of codons in gene expression? Draw a diagram showing how gene works. (4 points) The central dogma in genetics states that the coded information in the DNA is transcripted and transcribed into transportable units in messenger RNA (mRNA) which then programs them for synthesis of specific proteins. The messenger RNA carries the coded information to the ribosomes where the information is downloaded (transcription), translated and divided into codons each having three of the four base pairs. Transfer RNA then obtains a reflection of this information in a new strand in which the base pairs arrange themselves to become a reflection of the messenger RNA strand. Guanine on the m RNA translate to cytosine on the transfer RNA, and vice versa, thiamine and adenine too translate in the same
