El riachuelo mata en silencio





La cuenca matanza riachuelo es el río más grande en Argentina y uno de los más contaminado alrededor del mundo. Este nace en la provincia de Buenos Aires y desemboca en el Río de la Plata, tiene una longitud aproximada de 60 km y cubre una superficie de 2200 km² Comprende a la Ciudad Autónoma de Buenos Aires y 14 municipios de la provincia de Buenos Aires: Almirante Brown, Avellaneda, Cañuelas, Esteban Echeverría, Ezeiza, La Matanza, Lanús, Las Heras, Lomas de Zamora, Marcos Paz, Merlo, Morón, Presidente Juan D. Perón y San Vicente. La cuenca se divide en tres sectores; baja (altamente urbanizada), media (periurbano) y alta (rural y donde existen condiciones ambientales regulares).

El rápido crecimiento de la población afecta a la mega ciudad ya que Buenoa Aires no es una provincia del todo preparada para abastecer las necesidades del área urbana como el transporte, las viviendas, la provisión de un sistema de distribución de agua potable y de cloacas, la distribución de comida y energía, como tampoco la disposición de residuos domiciliarios e industriales. El aumento en la población requiere de un movimiento más amplio en la ciudad y en consecuencia aumenta la contaminación ambiental la cual si bien nos afecta a todos, las personas con un bajo nivel económico son las más influenciadas. El 9,16 % de los argentinos viven cerca de la cuenca Matanza Riachuelo que ocupa tan sólo un 0,6 % del territorio nacional. En la zona afectada viven 5 millones de habitantes, de los cuales el 35% de la población no tiene agua potable y el 55% no posee cloacas. Estas personas no tienen una vivienda digna y son expuestas día a día a distintas enfermedades, entre ellas predominan las cardiovasculares y las dérmicas, los tumores y diarreas, ocasionadas por el contacto o el consumo de aguas contaminadas que entre otras sustancias, poseen metales pesados y nitratos. Las malas condiciones sanitarias, el deterioro de la calidad de las aguas subterráneas y las recurrentes inundaciones que afectan las zonas bajas acentúan la transmisión y el contagio. Debemos de ser conscientes de la toxicidad del río y del peligro de salud que este provoca

En la cuenca Matanza Riachuelo hay radicadas más de 4000 industrias, algunas de estas utilizan en sus procesos de producción de sustancias tóxicas como metales pesados y compuestos organicos sinteticos, estas industrias en vez de reemplazar estas sustancias por otras, colocar una planta de tratamiento o pagar un servicio de recolección de residuos peligrosos, vierten esas sustancias directamente al sistema cloacal y pluvial. Los vertidos son conducidos por la red cloacal a la planta depuradora. Esta planta al carecer de sistemas de tratamiento para estas sustancias, las arrojan sin ningún control al curso del río. Otras industrias, que se ubican en los márgenes del río vierten sus descargas directamente en el y otras industrias vierten hacia los arroyos que finalmente desembocan en el río principal.

A pesar de ser el río más contaminado en el país, hay tiempo de revertirlo, no es un caso perdido, no hay que bajar los brazos y accionar al igual que el proyecto Acumar que ya hace varios años trabaja en limpiar la cuenca. Con responsabilidad y voluntad cada uno puede ayudar desde su posición para que esto se revierta y para reducir el impacto generado. No hay solo un responsable, todos somos culpables pero aún hay tiempo de remediarlo.

Clonación Terapeutica



La clonación terapéutica apunta a la reproducción de células madre que contenga el cromosoma del paciente para poder proveer, a través de las divisiones resultantes de su reproducción una alternativa de salud y vida. El estadio del desarrollo en que se detiene la división embrionaria es al rededor del curto o quinto día. 

El tratamiento con células madre mejor acreditado y utilizado es el del trasplante de células madre sanguíneas para tratar enfermedades y problemas médicos sanguíneos e inmunológicos o para recuperar el sistema sanguíneo después de tratamientos de cánceres específico. Se han utilizado las células madre cutáneas para el crecimiento de tejidos de pacientes que han sufrido quemaduras corporales graves, muy extensas o que suponen un riesgo vital. Tampoco es una solución perfecta: la nueva piel no tiene folículos pilosos ni glándulas sudoríparas. La investigación se centra en mejorar la técnica. En la actualidad, se están investigando otras aplicaciones en ensayos clínicos, que incluyen el uso de células madre para regenerar tejidos dañados, como los del corazón, piel, hueso, médula espinal, hígado páncreas y córnea, o para tratar cánceres hematológicos o de órganos sólidos. Todos los tratamientos con células madre son procedimientos especializados. Deberían realizarse únicamente en centros especializados autorizados por las autoridades sanitarias nacionales.

El ejemplo mas conocido de clonación terapéutica es la oveja Dolly ya que fue el primer mamífero en ser clonado con el fin de producir medicamentos en la leche de animales de granja.

Cuando se habla del banco de células madre se hace referencia al cordón umbilical. La sangre del cordón umbilical, contiene principalmente células madre denominadas hematopoyéticas. Estas células, tienen la capacidad de regenerar sus principales componentes de la sangre: glóbulos rojos, blancos y plaquetas. Pueden restablecer completamente la médula ósea y el sistema inmunológico cuando éstos están seriamente afectados. Según recientes investigaciones también podrían lograr lo mismo con otras células vitales como neuronas, células cardíacas, hepáticas, del páncreas, etc.

El tejido del cordón umbilical, contiene en su interior células madre llamadas mesenquimales. En condiciones normales, las células mesenquimales son las que se encargan de renovar las células del organismo que cumplieron su ciclo de vida útil y reparan los tejidos que han sufrido una lesión.

Yo estoy de acuerdo con la clonación terapéutica ya que es un proceso que resulta efectivo, es un avance de la ciencia que permite la cura de algunas enfermedades, ademas la ventaja es que al obtener celulas con la misma info genetica no existe riesgo de reacciones inmunologicas.

“An Apology Letter to Future Generations”



“An Apology Letter to Future Generations” es para mi un video original que te lleva a reflexionar acerca del cuidado del medio ambiente. “We use nature as a credit card”el señor que redacta pide perdón de parte de todos nosotros a futuras generaciones por haber dejado una tierra “vacía y sin vida” a cambio de dinero.

Se relaciona con el trabajo realizado de “huella ecológica” porque el video demuestra que cada acción que hacemos puede traer futuras y serias consecuencias, al final muestra que si cada uno de nosotros intenta de reducir su huella ecológica y toma más podríamos revertir parte de el error que hemos cometido.

La manera en que actuamos sobre el planeta nos convierte en los culpables de la desaparición de algunas especies, tanto animales como vegetales. “What ever you are fighting for racism or poverty, feminism, gay rights or any type of equality, it won't matter in the list because if we don't all work together to save the environment we will be equally extinct”. Por ejemplo, en una parte del video el hombre hace mención a los árboles y a los beneficios que este nos brinda, los describe en profundidad como si las futuras generaciones no tuvieran la oportunidad de apreciar y conocer lo que es un árbol ya que los cortamos todos abajo.

Estoy de acuerdo con el título ya que resume acerca de lo que va a tratar el video aunque si todos ayudamos a salvar el medio ambiente no va a hacer falta pedir perdón.

En conclusión, creo que lo que expresa el mensaje del video es muy emotivo donde nos lleva a abrir nuestras mentes y repensar si lo que estamos haciendo con el ambiente es lo correcto. Este video nos invita a dar lo mejor de nosotros y nos da esperanzas para revertir el problema.

Meiosis y Anomalias Cromosomicas



Meiosis

Es una de las formas de la reproducción celular, este proceso se realiza en las glándulas sexuales para la producción de gametos. La meiosis es un proceso de división celular en el cual una célula diploide (La célula madre que fue previamente dividida en dos células hijas idénticas a la proveniente) experimenta dos divisiones sucesivas, con la capacidad de generar cuatro células haploides.Anomalías Cromosomicas
Resultado de mutaciones que cambian el número de cromosomas o la estructura de un cromosoma . Pueden alterar la capacidad de la célula de sobrevivir y de funcionar.
Para entender este concepto primero debería empezar por aclarar algunos conceptos relacionados con los cromosomas.
Los cromosomas son estructuras que se encuentran en el núcleo de las células que transportan fragmentos largos de ADN. Todos nosotros tenemos normalmente 23 pares de cromosomas es decir 46 en total. La falta, exceso o ruptura de cromosoma puede aparecer en el nacimiento de un bebe. El problema es que Los errores en la cantidad o estructura de los cromosomas provocan una gran variedad de defectos de nacimiento, que pueden ser desde leves hasta severos.

R i e s g o d e e x t i n c i ó n


Una especie se considera en peligro de extinción, sea vegetal o animal, cuando todos los miembros vivos de dicha especie están en peligro de desaparecer. Pero, ¿qué causas son las que llevan a una especie a encontrarse en semejante riesgo?

Aunque existen causas naturales y fenómenos climáticos que alteran el orden y perjudican a un ecosistema, la mano del hombre es el eje del conflicto. A pesar de que ninguna de las acciones del ser humano que terminan impactando negativamente en el ambiente involucrando a especies inocentes se justifica, la más debatida e intolerable por gran parte de la población mundial es la caza indiscriminada. 

La caza es uno de los más antiguos factores que afectan a las especies alrededor del mundo y tiene diversos fines como por ejemplo:

  • Deporte
  • Fines comerciales (pieles - estuillas de marfil...)
  • Eliminación de grandes depredadores que afectan el ganado
  • Disturbio y persecución: incluyen la erradicación y destrucción de especies silvestres consideradas plaga.

Caso Yaguareté:

Este animal tuvo una amplia dispersión en Argentina la cual sostuvo bien entrado el siglo 20 y hasta la década de 1960 aún se seguía considerando a este especie como una “dañina” en las provincias de Catamarca y Salta. Hoy los yaguaretés son una rareza, extinguidos en casi todas las provincias y sólo protegidos en algunos parques nacionales.
Otra de las causas que conllevan a una especie al borde de la desaparición total es la destrucción de hábitats. La expansión de actividades humanas como la agricultura, la ganadería, construcción de ciudades y rutas entre otros factores, se basan en la alteración de un ecosistema, interrumpen el medio ambiente de los seres vivos provocando el desplazamiento y la muerte de los mismos. La deforestación con palas mecánicas es muy rápida y significó la drástica eliminación de fauna silvestre en el oeste de Santiago del Estero, noroeste de Tucumán y el este salteño.

Caso Misiones:
Lo que principalmente era una selva de alrededor 2.600.000 hectáreas, como consecuencia de la deforestación, sufrió una disminución radical. La espesura desapareció en más de la mitad del suelo provincial, en los últimos 100 años Misiones perdió 1.500.000 hectáreas.

La última de las causas más controversiales y severas en la gran lista de factores que tienen consecuencias en las vidas de seres animales y vegetales es la introducción de nuevas especies a un hábitat determinado. El término “introducción” hace referencia a la depredación o a la competencia de especies exóticas que fueron introducidos en un ecosistema. Pero ¿Por qué se lleva a cabo este cambio?. Algunas de las razones pueden ser estéticas, económicas y mismo para que estas compitan contra especies nativas.

Dato: En la Pcia. de Buenos Aires el 30% de las especies vegetales son exóticas.

The Wall, by Pink Floy




Deadline: 20th June
By: Tiraboschi Santiago, Ponti Mateo and Martínez Cerana catalina






1. The boy sees masks on the faces of the people in the train. Later he sees similar masks on the faces of the children in his fantasy. What is the meaning of that?

The meaning is tat the same for both situations, they are victims of a system. The white masks symbolizes that no matter who the person is, they are treated as if they don't feel anything, like robots that have to follow a structure no matter what. They don't have the opportunity of saying their thoughts, they have to continue with an order.

2. The riot scene ends and the camera returns to the boy in the classroom as the children recite the lesson. Think of a possible explanation for this.

The explanation could be that despite the children are reciting the lesson he doesn't forget what their thoughts and feelings are and he still has hope.


3. What kind of education does the movie portray? Use the song “The happiest days of our lives” to help you.

In the movie education is seen as a way to break what makes children unique and different. An education that is not real but is manipulative. Teachers are shown with absolute authority and power and they use it to humiliate their students by mocking the way of thinking or by hurting them if they do something they aren't supposed to. That is not a way of teaching, they are forced to learn a rude way.

4. Education is only one of the various social institutions the movie deals with. What others did you notice and how are they portrayed?

The movie apart from education also deals with work, family and society. Showing a rigid order and structure that, no matter wha,t it could not be break. This reflection remembers us to the part where the singer was feeling bad, he can't even move but anyway its duty and responsibility is to go to that concert.

5. We, in Argentina, often rely on education to solve most of our social problems. We blame education, or the lack of it, for many of them. Consider the huge success (described in the text below) of the song “Another brick in the wall” which claims “we don’t need no education” and compare it to what you think about education.

We believe that as much as in Argentina and in other countries, education is very important, it is what allows us to grow as a society and also the lack of it is to blame for some problems as a hole. We are in favor of education, but one like nowaday, one that allows you to grow in knowledge and as a person. a healthy education that takes your way of thinking and open new possibilities regarding it.

6. Up to what extent is education a way of “thought control”?

We think that education have lot to be with thought controlled, manly in children where theirs minds are still moldeables. One the other hand, nowadays teachers can not control our minds as they could at that time, because we can give our position and point of view.

7. Explain the meaning of the double-hammer symbol. Use the scene “In the flesh” to answer.

The meaning of the double-hammer is because the hammer can be use for only two things, opposite things, built and construct. Two facts that are constantly shown in the movie, for example we can relation the double-hammer with the education the children receive, where all their thoughts and ways of thinking are destroyed so as to construct new ideas.

8. The children falling into the meat grinder is a visual metaphor that makes a powerful point. What is the metaphor and what point does it make?

For us that visual image is a symbol of hopeless, of accepting that they can't do nothing at respect. They knew there is a way of learning that will not change where their creativity and imagination are prohibited, they don't have freedom of expression and their minds are completely washed and ruined.

9. What is the wall? Can you say whether it is a good thing or not?

In our opinion the wall can represent two ideas;
The wall could be a division, could be the thing that separated the different thoughts and behaviours on the other hand could be related with the society being created at that time, all with the same way of thinking and with their minds manipulated ending up being a cold and equal brick in the wall.

Notre visite à l'Alliance Française



L’ Alliance Française




Le mardi 17 mai, nous avons visité L´Alliance française. Nous avons partis de l'école à huit heures vers le centre ville, et bien, le voyage a été très long et fatigant, nous étions désireux d'arriver.
Plus tard, nous trouvons un bâtiment élégant et très joli. Nous avons ensuite être divisés en deux groupes d'étudiants sur notre niveau de français (DELF A1 ou A2). Tandis qu'un groupe est allé à la médiathèque, l'autre a vu des vidéos différentes dans une salle, une classe de compréhension de l’orale. Nous avons participé et aussi nous avons parlé française mais timidement. Les deux groupes ont traversé ces expériences amusantes et agréables mais malheureusement ces activités ont duré peu de temps. La visite a été excellente et nous avons appris beaucoup!

A veces más es menos

Trabado: Código de Barras

Idea Principal...

Nuestra materia se llama Ambiente, desarrollo y sociedad, observando la imagen fuimos invitados a ver cual es la relación entre esta y nuestra materia y luego de reflexionar encontré más de una semejanza.

Esta imagen está ampliamente relacionada con el consumismo, de cómo hoy en día se crean cada vez más aparatos tecnológicos haciendo que el tuyo sea un modelo viejo “obligando” a uno a desechar algo que todavía sirve y a seguir consumiendo. Parecemos esclavos de compra al sentir una necesidad que no es real, es una necesidad creada erróneamente por la sociedad que provoca que nosotros mismos nos encerramos, nos pongamos detrás de las rejas, perjudicandonos, destruyendo todo lo que tenemos dejando a nuestro mundo sin vida y quitándoles a las futuras generaciones la oportunidad de observar las maravillas que el mundo nos ofrece. Produciendo una cantidad de contaminación impensable por solo un capricho humano, obtener el último modelo de celular para así estar a la moda y encajar con la sociedad que se presenta en estos tiempos





La imagen también me llevó a pensar en...

Además esta imagen también me lleva a relacionarla con el supermercado y como destruyen el medio ambiente solo para obtener lo único que pareciera importar en este mundo, plata. Contaminado ríos, mares, suelos y aire solo por industrias, deforestando solo por papel, acelerando y alterando el proceso del cultivo solo por obtenerlo con mayor rapidez y a mayor cantidad entre tantas cosas.


Por último relacionando el código de barras otra vez con el supermercado recordé un proyecto realizado hace 5 años atrás, donde observamos que varios productos a la venta llevaban más de un envoltorio, el cual no era necesario y el cual contamina sin razón.


Responsabilidad es lo que marca la diferencia

E la  materia Ambiente, Desarrollo y Sociedad fuimos invitado a ver un vídeo para darnos cuenta de que necesitamos para hacer consumidores responsable, una vez hecho esto debíamos crear un mapa conceptual a cerca de lo vito en dicho vídeo.
Acá dejo el link de mi trabajo:

http://popplet.com/app/#/3135186

Una frase lo dice todo...





Graciela Catalá (Profesora de Ambiente Desarrollo y Sociedad) nos compartió una serie de vídeos de National Geographic donde mostraba lo que uno consume durante toda su vida (Básicamente habla de la huella ecológica). Luego de mirar este vídeo debíamos elegir, respetando una foto que ella nos dio, una frase de un famoso y luego vincularla con el vídeo visto.



La frase que yo elegí es “Todo parece imposible hasta que se hace”.

El vídeo, como ya mencione, trata acerca del consumismo de cada persona durante toda su vida y muestra que sin darnos cuenta cada uno de nosotros genera una cantidad impensable de basura. Hay un par de frases dichas en el vídeo que me gustaría citar ya que pienso que ayuda a englobar y de alguna manera resumir lo visto en dicho vídeo. Estas citas importantes a resaltar son:

· “Nos hemos enamorado de todo lo que venga primorosamente lavada empaquetado y envuelto.”

· “Envoltorios aumentan velozmente, cada uno de nosotros tira mas envases de comida que productos en sí mismo”

· “Todo lo que llevamos dice algo de quienes somos”(Esto se refiere a la compra compulsiva de ropa)

· “Compraremos casas, construiremos un hogar y ganaremos dinero para gastar en todo lo que la vida nos pueda ofrecer, y aquí es donde la huella comienza a hacerse realmente grande.”

· “Cada uno de nosotros producimos cuarenta toneladas de basura”

· “..... y miles de bienes más de los que aún no se han inventado y que pronto no podremos vivir sin ellos”

Yo creo que la frase que elegí se relaciona con el vídeo ya que uno cree que es imposible revertir la cantidad increíble de basura que se generó durante estos últimos años. Se que mucha gente piensa que con solo su cambio no ayuda, es decir, creen que de todas las personas que existen en el mundo si solo el o ella deja de consumir esto no haría un gran efecto entonces no valdría la pena, todo lo contrario, si cada uno de nosotros toma en consideración lo mal que le hacemos a el medio ambiente y somo lo suficientemente capaz y voluntariosos de reducir aunque sea un poco nuestra huella ecológica, el cambio sería muy grande. Por eso debemos cambiar algunas actitudes y esforzarnos en cuanto esta cuestión para finalmente frenar con todo esto y darnos cuenta que si trabajamos todos juntos nada es imposible hasta que se hace.

United States coldest case murder conviction



Maria Ridulph Case

The kidnapping and murder of Maria Ridulph was the oldest cold open case to reach the courts in the history of the United States.
Starting point:
On December 3rd 1957, 7 year old, Maria Ridulph was abducted from Sycamore, Illinois. After dinner Maria was playing in the snow with her friend Kathy Sigman when a young man who called himself “Johnny” approached the girlies and offer them a piggyback ride. A few minutes later, Kathy went to her house to fetch her gloves because is was freezing outside but when she came back Johnny and Maria were nowhere to be seen.

Looking for Maria:

Kathy went to the Ridulph’s house to tell everybody what had happened. Chuck, Maria’s older brother went outside to look for the girly but there was not any signal. Rapidly, the men ran to the house of Ralph and Eileen Tessier (two blocks from the Ridulph). Ralph had a hardware store and the idea was to carry on with the search asking the owner to collaborate with flashlights.

Police investigation:

The following days, the police questioned Eileen Tessier about the events of December 3. John stepsisters heard how his mother told the police something they knew it was not true: that John had been home all night.
In addition, there were conflicting reports about the exact time of the disappearance of Maria. The Sycamore police chief told FBI agents that Kathy and Maria had gone out to play at 18:02, but the county sheriff said Maria had not called Kathy until 18:30. Maria's mother later changed his statement and said the girls could have gone outside even at 17:50.
Kathy Sigman spent hours watching carefully the pictures of people on file by the police, but could not find Johnny.
The local police was sure no one in Sycamore could have done such a thing. It had to be an action done by a trucker or someone passing by. The FBI was not so sure. There were several potential suspects in the village. Police questioned all "known sexual deviants". They investigated a voyeur and followed clues that led up to two men nicknamed "Commando" and "Mr. X”.

Maria’s body is found:

Five months later Maria's body appeared, 190 kilometers from her home. A man found his skeleton under a fallen tree on a farm. The cause of death couldn’t be determined.

John Tessier/ Jack Mccullough

The FBI initially showed interest in Tessier as a suspect, a boy from the neighbourhood nicknamed “Commando”. Three days after Maria disappeared, an anonymous woman warned that a young man named "Teschner" who lived in the neighborhood matched with the description of the suspect. A pair of FBI agents showed up at the Tessier house.
Tessier told them then, and continues stating today, he was in Rockford, Illinois, about 65 kilometers northwest of Sycamore, when they kidnapped Maria. His parents supported his story, and was verified by an irrefutable fact: someone who gave his name made a call from Rockford to the Tessier’s house at 18:57, on 3 December 1957.
There was much discussion about the time of the disappearance of Maria. If the kidnap was done around 19:00, then Tessier had an armored alibi. But if they did around 18:15, then something not locked. John could have gone to Rockford Sycamore car and having arrived at 19:00 before disposing Maria’s body.
No one disputes that John traveled to Chicago for a physical test at the military recruiting center. Tessier said he was walking around Chicago the afternoon of December 3, stood in a cabaret show and then went to Rockford to leave the papers in the recruitment center. Recruiters confirm that they saw by the office between 19:15 and 19:30 that afternoon.
Two days after the FBI interrogated Tessier, he was subjected to the lie detector test. When asked if he had ever had sex with children, Tessier admitted having been involved in "some kind of sex play" with a girl but had occurred several years before. He stated that the episode was over and had no relationship with Maria.
Those details did not raise suspicions at the time. Nor the contradictory versions of his mother when she told the police that his son was home all night and the FBI that was in Rockford that night. Finally, an FBI agent concluded his report by emphasizing: "There will not be other research related to this suspect”
New Investigation:

In January 1994, Eileen Tessier was on the verge of death but she had a secret she didn't want to take to the grave. "Janet!" She called her daughter, according to the statement made to the court itself many years later. Janet ran to her mother's bed. Eileen grabbed her wrist and spoke.
“That girl who disappeared. It was John. You have to tell someone.” Although Janet was a baby when her neighbor of seven years disappeared in 1957, she knew immediately what her mother was confessing, her brother, John kidnapped and killed Maria Ridulph.
It was a decade later when Janet Tessier tried one last time after several denies to tell her testimony. She sent an email to the Police of Illinois: "A seven year old girl named Maria Ridulph disappeared. Her remains were found in early spring of 1958. I think John Tessier, of Sycamore, is responsible for her death. Today he lives around Seattle under the name of Jack McCullough. "
Her urge caught the attention of a boss. He called Janet and she told him how her mother had told her on the deathbed that his brother had kidnapped and killed Maria. "I can not promise anything," said the police chief, "but we will try."
He assigned the case to two men, Larry Kot and Brion Hanley. Kot, 57, was a civilian analyst and worked for the police in Illinois. “I had never heard of the case Ridulph”, but soon he gathered information that cast doubt on the suspect's alibi.
Brian Hanley, 41, made the preliminary work and began by Janet Tessier and her brothers. None had nothing good to say about John, especially Jeanne who was sexually abused at the age of 14 by John.

Crime Chronology:
Tessier said he was in Chicago on Tuesday morning December 3, getting a medical checkup. Kot found that it was true. But he realised that Tessier left the recruitment center at noon. He was later seen in Rockford, almost 150 kilometers from Chicago, about 19:15. But there was no witness to verify his whereabouts between noon and 19:15, which meant he could have easily gone back to Sycamore before appearing in Rockford. Kot examined the account of another witness, the dealer of heating oil. The man knew Kathy Sigman and her family and remembered that the girl had greeted him when he was delivering fuel into a nearby house. He arrived there at 18hrs and was 15 to 20 minutes unloading the oil. When he left, about 18:20, he did not see the girls.
Kot concluded that Maria had been kidnapped before 18:20. If Tessier parked his car in the back entrance, where they found the doll Maria, Rockford could have been addressed directly with the girl in her car. It was a journey of 64 kilometers, and could have come to Rockford in less than an hour.
The call made from Rockford to the house of Tessier, was a key part of John alibi also fit into this new timeline. Phone records showed that the call was made at 18:57 but did not point from which place of Rockford had been realized. Tessier could have called home from a pay phone outside the village.It may be that Tessier's alibi was not as infallible after all.

Arrest:

Hanley took six photos and placed them on the table. Five of them had been removed from Sycamore school yearbook. The photo of John Tessier was a little different. Kathy eliminated several pictures immediately but looked at two: No. 1 and No. 4. He studied for two long minutes. "He is," she finally said, noting the number 4. I had no doubt. Now the detectives had a real suspect. It was time to visit to "Johnny".
Seattle two policemen who had joined the case learned that the "person in question" worked in a block of apartments for elderly people. He called himself Jack McCullough because he had changed the name in the early 90's when he married his fourth wife, Sue, for nearly two decades.
He was a former policeman. The agents examined his file and discovered a lurid past. They learned that he had been dismissed from the police after being accused of abusing a child under 15 years who had run away from home. They also found out about the photo of her 11 year old daughter naked hidden in the bottom of a drawer. Police arrest McCullough on June 29, 2011. Jack McCullough returned to Sycamore handcuffed on July 27, 2011, the same day authorities exhumed the body of Maria Ridulph.
McCullough would face trial for rape before facing trial for the murder of Maria.
Judge Robbin Stuckert raised many doubts after people tell their testimonies which were related to John’s dirty and obscure attitudes. He wondered why the applicant had waited decades to publicize the crime. But the verbal war between Stuckert and Campbell led the judge to withdraw from the murder trial. The case was referred to Judge James C. Hallock.
During the trial, in September 2012, the statement Kathy Sigman on stage was decisive when retold how a stranger who called himself Johnny offered them a piggyback ride, and how Maria and Johnny disappeared when she went home to find her mittens.
Kathy stood firm when she was shown the six pictures of the suspects she had already seen in 2010. Janet Tessier testified about the statement of her mother on her deathbed.
Then three prison informers confirmed that in a conversation with McCullough, he had admitted that he had killed Maria. The trial lasted four days. No McCullough took the stand, so he could not present his alibi. The judge issued the verdict. Guilty on all counts: murder, kidnapping and abduction of a child. And Johnny went to prison.





Jack McCullough, 76, was serving a life sentence for the 1957 murder of 7-year-old Maria Ridulph. Judge William Brady threw out the conviction after a prosecutor found "clear and convincing evidence" that McCullough was wrongly found guilty.
McCullough's lawyers and DeKalb County state's attorney Richard Schmack argued that McCullough's conviction was based on false testimony, improper legal rulings controlling the evidence presented, and a timeline that was tweaked some 50 years after the fact to rule out McCullough's alibi.
McCullough has long insisted that he couldn't possibly have abducted and killed the child because he was 40 miles away in Rockford, Illinois, talking to recruiters and trying to enlist in the U.S. Air Force when she was taken. The prisoner was set free on 2016.

Expers



Expert means a person who has a broad knowledge in a specific field, because of their experience and skills they are seen as a credible source. Anyway because they are experts does not mean that they don't make mistakes, they still are human beings and all human beings make mistakes hence we can say that experts are not always right.

I don't agree with what illich argues in Item A, in my opinion what he say is wrong because i consider that housing hygiene, diet are some of the main factors affecting the health population, on the other hand, I think that changing this will not solve the complete problem, maybe it will avoid some illnesses anyway medical establishment is essential for our life. We can't treat society as a whole, sometimes we have to focus in an individual person. This “kind of mistake” could be associated with changing expertise”

In item C “expert” treat a topic of africans slavery, they say that the wiah they have of being free is a desses, when in fact they have the right of doing whatever they like instead of being obeying orders from someone.

In item D happens the same as in C but instead of the black race they talk about gays and take this as a mental dresses, while in fact what they're doing is discriminating.

In conclusion, none of the three cases is right, being an expert and knowing about the topic doesn't mean that you cannot be wrong.

Arte desde otro punto de vista



Después de haber visto el vídeo que la profesora de Ambiente Desarrollo y Sociedad, Graciela Catalá público en su blog, ( Acordeondigital,blogspot.com) ,acerca del famoso artista argentino Antonio Berni, los alumnos de 6to naturales fuimos invitados a reflexionar sobre el mismo.


Antonio Berni, quien fue un pintor grabador y muralista argentino, muestra su arte creando a un personaje llamado Juanito Laguna, a través de este, el artista demuestra con una serie de obras realistas y chocantes como es la vida en la pobreza, como es la vida para las personas que lamentablemente no pueden satisfacer sus necesidades básicas, para aquellas personas que no pueden consumir lo necesario.

Por otra parte, Lo interesante es que usa la basura como material de su obra. Cosas que la gente (probablemente de la burguesía) deshecha son transformadas en arte. ya que las cosas que a uno le podrían servir o que tal vez se podrían reciclar son reemplazadas por algo mejor y esto tiene que ver con la obsolescencia programada y el consumismo.

Abortion

Thinking Skills: Make an essay about you topic: Abortion


Abortion must be legal? Abortion is a very delicate and complex topic discussed all around the world that lead us to lots of disagreements. When did the life of a human being start? nowadays we still having doubts about it some people believe that human being life start at conception, others at birth, and others support that is depending on the days, weeks or months  the mother have been pregnant.


To begin with, We all know that we have an important right, which is the right of life, and because of it I think that abortion is ethically wrong. The fetus is a human being and therefore he or she had the right to life and nobody should be able to take out this opportunity, no one should have the power of abortion, you are killing a person, your own baby
.
In my opinion is unjust that millions of babies have to die because of a selfish decision,  abortion should not be an escape route for those who have failed to take responsibility with regards to suitable protection from unwanted pregnancy and that is why I don´t agree, in some way, about the right of the women  to ownership her own body. However there are some exceptions, What is the women pregnant has been raped? The mother could end the life of the fetus if his own life is in danger?


From my point of view, is very difficult to define a correct answer to this two questions, I am just saying my opinion and I think that although in the two cases the baby is innocent, the mother should have the right of abortion. For example, If the women has been raped, she had not the fault of having a baby and she was not looking for a baby and she probably is to jung so as to live everything aside and take care of  she or he, apart from this, probably the pregnancy will be a constant reminder of the sad and horrible situation she had suffered and this baby will not have a father.

In conclusion, there are some women that abort anyway, knowing is illegal and they do it in a danger way. So I think I would let abortion be legal and safe only because this reason. On the other hand, I am against abortion, it might be a difficult decision, no doubt, one of the biggest decision of your life but i think I would not do it.

Mad Men

In thinking skills class whit our teacher, Maria Brito Evans, we saw a video of the serie, mad men where cigarettes advertisement were discussed, later we must answer some questions our teacher left in edmood.

1. Found some of the vested interests in this scene. How do these work?
2. Why is Peter's idea rejected, and why is Don's idea accepted?
3. Publish your answers on your blogs and the link to thdentify sem here in Edmodo. Before you do that, produce an introduction to the task ("We watched a video...). Also, include a relevant picture (related to Mad Men, advertising ciga

1)One of the first vested interests that appeared on the video is when Don explains his idea. According to it, tobacco is seen as an element that gives a person happiness (though in fact, it gives dependence), the way Don explains his thought, makes him avoid mentioning part of the real information which are the terrible effects smoking produces.

Other vested interest we could identify was when the men rejected Peter's idea. These men ignore that opinion because it was not convenient for their business

2) Peter’s idea is rejected because he made reference of the great damage tobacco creates in people's life, mentioning it's a life danger and it was obviously, not beneficial for the company. On the other hand, Don’s idea was quickly accepted because it did not mentioned every risks tobacco caused. In addition, Don portrayed tobacco as something people need to be happy making propaganda still look attractive. rettes, advertising, vested interest, etc.)

3)

 

Cigarette Advertisment


1)How does advertising help tobacco companies to defend their vested interest?
2)Cigarettes advertising distorts the truth. Briefly comment in this view.

Advertising help a lot in tobacco company because is a way to attract or persuade people to buy the product although they are not telling the completely truth about what smoking could produce.

People who were in-charge of creating tobacco advertisement had to convince people that smoking have lots of positives thing, (for example in that time the person who smokes was seen as a cool person) so as to in a way make people see that cigarettes are not as ad as they think.

Nowadays there are not more tobacco advertisements because people already know how bad tobacco is, in addition its now mandatory that all cigarette packet must have a little advertisement about the damage the cigarette could cause,  anyway many people still smoking because of a addiction or because they like it.

Women in Politics

    
    How far is a women qualified to fulfilled  an important political role?



Nowadays women can have the power of leading a country, when some years ago they only were in charge of cooking, cleaning and taking care of their children. They were not able to vote or express their opinion or take decisions. On the other hand, the change in women’s power improves and advances, slowly but surely, and how now women are qualified to fulfill an important political role. The role of women in politics had been changing with the pass of the time and now it is usual to find women occupying political positions in eastern and western countries, in some cases Heads of State. According to sociologists, during the second half of the twentieth century there has been the biggest transformation in history, and that especially since the decades of the 60s and 70s when the efforts and struggles of women suffragettes initially started in countries as diverse as England, France or Mexico. However, it was not until the late '90s that women began to had important positions in the governments of different ideological and democratic dyes worldwide.

There are a lot of women that we can mention as the pioneers in international politics. I tried to select the ones that I thought as more representatives, beginning with Lydia Chapin Taft who in 1756 was the first legal woman voter in America. Later in 1882 Aletta Jacobs was the first woman in the Netherlands to attempt to register to vote but her application was denied. New Zealand is credited today for being the first nation to grant all women the right to vote in 1893. In 1930 Alexandra Kollontai is appointed Ambassador from the Soviet Union to Sweden, becoming the first woman Ambassador in modern history and in 1966 Indira Gandhi became the first Prime Minister of India. Soong Ching-ling was the first non-royal woman to lead the state of China in 1968.

In 1979 Margaret Thatcher became the first woman Prime Minister of the United Kingdom. She served in that position -- winning re-election in 1983 and in 1987 -- until resigning in 1990. She was called “Iron Woman” because of her strong personality. During her leadership Argentina and Great Britain were in war reclaiming the Malvinas’ (Falklands) sovereignty.

Another outstanding woman is Angela Merkel, who was elected Chancellor of Germany in 2005 doing a great job in her country, making the Germany one of the strongest, if not the strongest, countries in the European Union.

Senator Hillary Clinton was the first woman to ever be considered as a top candidate (or even a serious one) for the US Presidency in 2007, but she lost the Democratic Party Nomination to Senator Barack Obama.

In our country I must mention Eva Duarte de Perón, who was the second wife of Juan Domingo Perón and who did much for women's rights and in 1947 she achieved the law that allowed Argentine women to vote. In 1974 the third wife of Juan Domingo Perón, María Estela (Isabelita) Martínez de Perón succeeded her husband and became the first woman President of Argentina and the first female head of state in the Americas. In 2007 Cristina Fernández de Kirchner was elected President of Argentina and reelected in 2012. She is still governing our country.

Going back to what I have mentioned, women were and are exposed to several barriers that may impact their desire to run for a political career. These barriers are for example sex stereotyping, political socialization, lack of preparation for political activity, and balancing work and family. Now women in government are under-represented in most countries worldwide, in contrast to men. However, women are increasingly being politically elected to be heads of state and government.

In conclusion, I think women are capable as men to lead a country. In my opinion, there were many women who knew how to carry forward the whole country, and they did it without men’s help, may be that with some mistakes but we all make mistakes. From my point of view it’s not an easy task. We must observe the preceding women as an example, learning from their successfulness and their mistakes. We must prepare carefully and thoroughly to finally achieve an equal respect as men have.
