Reporte consular para ciudadanía por derecho de sangre

Reporte consular para ciudadanà ­a por derecho de sangre El reporte consular de nacimiento en el extranjero prueba que una persona nacida fuera de Estados Unidos es ciudadana americana por derecho de sangre. Es el equivalente al acta o certificado de nacimiento que se emite a todas las personas que nacen en los EEUU. Y este reporte sirve para demostrar que se es ciudadano americano, para poder sacar el pasaporte y para obtener otros beneficios que corresponden por la ciudadanà ­a como Medicaid, Chip, etc en el caso de ir a vivir a USA. Datos bsicos de la ciudadanà ­a americana La nacionalidad de los Estados Unidos puede adquirirse por cinco caminos distintos. La mayorà ­a la adquieren por lo que se conoce derecho de suelo, pero este artà ­culo trata de un caso especial que tambià ©n es relativamente frecuente: la obtencià ³n de la ciudadanà ­a por derecho de sangre.   Es decir, un  menor adquire la ciudadanà ­a americana a pesar de haber nacido en otro paà ­s porque el padre, la madre o ambos son americanos en el momento en el que tuvo lugar su nacimiento. Quià ©n puede solicitar el reporte consular de nacimiento en el extranjero, cundo y cunto cuesta Para poder solicitr el reporte consular es necesario que la nacionalidad estadounidense cumpla todos los requisitos para transmitirse. No es suficiente que el pap o la mam sea ciudadano de los Estados Unidos. Los requisitos son distintos segà ºn el progenitor estadounidense sea el padre o la madre o ambos y tambià ©n de su estado civil. Si se cumple lo que establece la ley, entonces se podr solicitar el reporte consular. El padre o la madre que es ciudadano estadounidense (o ambos, si es el caso) son los autorizados para pedir el reporte consular. Tambià ©n puede hacerlo cualquier padre, si tiene una orden judicial en la que se le reconoce en exclusividad la guardia y custodia sobre el menor. Incluso es posible que el padre o la madre americana autoricen a otra persona a que realice la peticià ³n. En este caso, se necesitar una declaracià ³n jurada notarizada concediendo la autorizacià ³n. Adems, debe solicitarse antes de que el nià ±o o la nià ±a cumplan los 18 aà ±os de edad. Pero es muy recomendable que se haga cuanto antes, incluso inmediatamente despuà ©s del nacimiento. En todo caso, debe solicitarse antes de que el menor viaje a los Estados Unidos por primera vez. Esta gestià ³n tiene, en la actualidad, un costo de $100. Cà ³mo se tramita el Reporte Consular de Nacimiento en el Extranjero El primer paso es ir a la pgina de internet de la oficina consular ms cercana y seguir las instrucciones para hacer una cita para solicitar el reporte (CRBA, por sus iniciales en inglà ©s). A continuacià ³n hay que preparar y conseguir la documentacià ³n que se necesita para ir a la cita al consulado. Primero, hay que rellenar el formulario DS-2029. Es muy importante recordar no firmarlo, ya que ese es un paso que se debe hacer ante el oficial consular. Tampoco se debe rellenar los apartados 28/29 y 30, que lo har el cà ³nsul. Adems, es necesario aportar la siguiente documentacià ³n: 1. -El acta de nacimiento del nià ±o. Es fundamental que conste el nombre completo, correcto y debidamente deletreado del padre y de la madre (salvo en los casos de maternidad en solitario). 2.- Prueba de que el padre, la madre o ambos son ciudadanos americanos. La mejor forma de probarlo es con un pasaporte estadounidense en vigor. Otros documentos que se admiten son el acta de nacimiento, si ha nacido en Estados Unidos, o el certificado de naturalizacià ³n, si nacià ³ en otro paà ­s, emigrà ³ a EEUU y en algà ºn momento en el pasado obtuvo la ciudadanà ­a americana. 3.- Si se est casado, prueba del matrimonio. Asimismo, si se ha estado casado con anterioridad es necesario mostrar un documento que acredite cà ³mo acabà ³ el matrimonio anterior: viudedad, divorcio o anulacià ³n. 4.- Una declaracià ³n jurada por parte del progenitor estadounidense que se llama Affidavit of Parentage, Physical Presence and Support. En dicha declaracià ³n el padre o la madre juran que han vivido en Estados Unidos el tiempo necesario para poder transmitirle su nacionalidad al hijo o hija nacidos en el extranjero. Y es que no basta con ser americano, hay que haber vivido en USA cierto nà ºmero de aà ±os y poder demostrarlo. Tener presente que las reglas son diferentes segà ºn el caso. Se piden distintos aà ±os de residencia en EEUU segà ºn se trate de padre o madre o si estn solteros o casados. Adems, no basta con declarar que se ha vivido el tiempo requerido, hay que poder demostrarlo con documentacià ³n como por ejemplo: registros escolares, pasaportes anteriores, pago de impuestos, cotizaciones al Seguro Social, rà ©cords mà ©dicos, contratos o facturas a su nombre, rà ©cord militar, etc. Recibir el Certificado de Registro de Nacimiento en el Exterior Los consulados tramitan esta gestià ³n, pero el documento se emite en Estados Unidos. Por lo tanto hay que indicar dà ³nde se quiere recibir, dndose la opcià ³n de una direccià ³n en Estados Unidos, en el paà ­s de residencia (en algunos casos) o en la oficina consular. En otras palabras, el dà ­a de la entrevista no se saldr del consulado con el certificado en la mano. Consejos a tener en cuenta Los documentos deben ser originales o copias autentificadas por la autoridad que las emite con el sello oficial correspondiente. No sirven fotocopias ni tampoco copias notarizadas. Salvo casos muy excepcionales, siempre se devuelven esta documentacià ³n. Las reglas que regulan la transmisià ³n de la nacionalidad americana de padres a hijos cuando à ©stos nacen en el extranjero ha cambiado a lo largo de los aà ±os. En los casos de duda, hay siempre que verificar quà © ley aplicaba en el momento del nacimiento del hijo de un americano.   Adems, hay que tener en cuenta que aunque hoy en dà ­a es muy difà ­cil perder la nacionalidad americana, hasta hace recientemente poco tiempo eso no era asà ­. Para estos casos a veces es posible recuperar la ciudadanà ­a. Por à ºltimo, cuando un ciudadano americano no puede transmitir a su hijo la nacionalidad por no cumplir con el requisito de nà ºmero de aà ±os vividos en EEUU, a veces es posible tramitar para ese menor una naturalizacià ³n especial adquiriendo la ciudadanà ­a por los abuelos. Este es un artà ­culo informativo. No es asistencia legal para ningà ºn caso concreto.

Ostrich Egg Shells

Ostrich Egg Shells The broken pieces of ostrich egg shells (often abbreviated OES in the literature) are commonly found on Middle and Upper Paleolithic sites throughout the world: at the time ostriches were much more widespread than they are today, and indeed were one of several megafaunal species which experienced mass extinctions at the end of the Pleistocene. Ostrich egg shells offered protein, a palette for artwork, and a way to carry water to our ancestors over the past 100,000 years, and as such, they are well worth considering a raw material of interest. The Qualities of an Unbroken Egg The ovate eggshell of an ostrich averages 15 centimeters long (6 inches) and 13 cm (5 in) wide; with its contents intact an egg weighs up to 1.4 kg (3 pounds), with an average volume of 1 liter (~1 quart). The shell itself weighs about 260 grams (9 ounces). Ostrich eggs contain about 1 kg (2.2 lbs) of egg protein, equivalent to 24-28 chicken eggs. An ostrich hen lays between 1-2 eggs each week during the breeding season (April to September), and in the wild, hens produce eggs for some 30 years during their lives. Ostrich eggshell is composed of 96% crystalline calcite and 4% organic material, mostly proteins. The thickness (averaging 2 millimeters or .07 in) is made up of three different layers that vary in structure and thickness. The hardness of the shell is 3 on the Mohs scale. Since its organic, OES can be radiocarbon dated (typically using AMS techniques): the only problem is that some cultures used fossil eggshell, so you have to have additional data to back up your dates, always a good idea anyway. Ostrich Egg Shell Flasks Historically, ostrich egg shells are known to have been used by African hunter-gatherers as a light-weight and strong flask or canteen to store and transport various fluids, usually water. To make the flask, hunter-gatherers puncture a hole in the top of the egg, either by drilling, punching, grinding, cutting or hammering, or a combination of techniques. Thats been difficult to identify in archaeological sites, which typically include only a few eggshell sherds. Intentional perforations could be considered a proxy for the use of eggshell as a container, and based on the perforation, an argument has been made for flask use in southern Africa at least 60,000 years ago. Thats tricky: after all, you have to open an egg to eat whats inside anyway. However, decoration on eggshells has recently been identified which supports the use of flasks in Howiesons Poort contexts in South Africa at least as long ago as 85,000 years (Texier et al. 2010, 2013). Refits of the decorated OES fragments indicate that the patterns were placed on the shell before the shell was broken, and, according to these papers, decorated fragments are only found in context with evidence for purposefully cut openings. Flask Decorations The decorated fragments research is from the Middle and Later Stone Age Diepkloof Rockshelter in South Africa, from which has been recovered over 400 pieces of engraved ostrich eggshell (out of a total of 19,000 eggshell fragments). These fragments were deposited throughout the Howiesons Poort phase, especially between Intermediate and Late HP periods, 52,000-85,000 years ago. Texier and colleagues suggest that these markings were intended to indicate ownership or perhaps a marker of what was contained in the flask. The decorations identified by the scholars are patterns of abstract parallel lines, dots, and hash marks. Texier et al. identified at least five motifs, two of which spanned the entire length of the HP period, with the earliest decorated eggshell fragments from 90,000-100,000 years ago. OES Beads The bead-making process was recently documented archaeologically at the Geelbek Dunes site in South Africa, dated between 550-380 BC (see Kandel and Conard). The bead-making process at Geelbek began when an OES breaks, purposefully or accidentally. Large fragments were processed into preforms or blanks or made directly into discs or pendants. Processing the blanks into beads involves the initial drilling of angular blanks followed by rounding, or vice versa (although Texier et al. 2013 argue that the rounding process almost always follows the perforation). Mediterranean Bronze Age During the Bronze Age in the Mediterranean, ostriches became quite the rage, with several occurrences of elaborately decorated eggshells or eggshell effigies. This came at the same time as state-level societies in the fertile crescent and elsewhere began keeping lush gardens, and some of them included imported animals including ostriches. See Brysbaert for an interesting discussion.

Essay Title Why is linking serial offences not an exact science

Title Why is linking serial offences not an exact science Critically examine this view using real example to illistrate your points - Essay Example The insistence on the number of victims being a minimum of three poses a problem in that it may be viewed more as a counting exercise rather than the indicator of a particular state of mind! As stated by Mouzos & West: "a killer who murders two victims and is apprehended by police prior to committing additional murders, and who exhibits the same or similar characteristics as one who kills five, is also important to our understanding of this phenomenonThe ability of law enforcement agencies and the wider community to understand and manage the risk posed by the serial killer is intrinsically linked to a comprehensive understanding of the dynamics of the individual and the motivating factors."(Serial Murder-Australia, 2007) Mouzos & West suggest that further study should be done on those who commit two instead of more murders, and this can be compared with studies already done of the motivations of serial killers. This would lead to an understanding of why-apart from being caught-those who stop at two murders on separate occasions do so. (Serial Murder-Australia, 2007) The task of linking serial offences cannot be an exact science in the way Physics or Chemistry are, because of the human element involved. Any study of human volition cannot be exact, however much that study may claim to depend on precise mathematical formulae or other measurements. It is the ability to predict, which may be considered as the basis for categorizing a science as exact (pure science) or inexact (humanities). Linking serial offences can ultimately only indicate likelihood rather than certainty, because this involves human volition-both in the commission of the offence by the perpetrator, and in the interpretation of data (this involves discretion) relating to offences. Let us examine the results of studies on the predictability factor in linking serial offences. The task of "prediction of dangerousness"(Norko & Baranoski, p73, 2008) gained importance in medicine in the seventies and eighties, not because of clinical wisdom or the "quest for testable hypotheses about human behaviour"(Norko & Baranoski, p 73, 2008) but out of a practical need to differentiate between patients who needed to be treated as in-patient, and out-patients, and to decide who could be permitted voluntary care, and who had to compulsorily be given treatment. The criterion of dangerousness was put forward as the basis for making these decisions. This dangerousness criterion and the necessity for doctors to predict its violent eruption became enshrined in several legal decisions between 1960 and 1980. However, as a reaction to this, psychiatrist Bernard Diamond declared that "Neither psychiatrists nor other behavioural scientists are able to predict the occurrence of violent beh aviour with sufficient reliability to justify the restriction of freedom on the basis of the label of potential dangerousness." (Diamond, 1974, p 452 in Norko & Baranoski, pp73-74,2008) Research studies undertaken since 1990 have concluded variously. There are studies that demonstrate a) linkages between mental illness and violence, b) others that do not support such a linkage, and c) yet again other studies that "demonstrate the importance of nonmental health variables in relation to violence."(Norko & Baranosk

Germans that you hold to be true and admire Essay

Germans that you hold to be true and admire - Essay Example All they want is clear and overt expression of the underlying feel that makes them say what they want. Americans are not much different either. Americans also feel comfortable making direct and straightforward speech. Both Germans and Americans prefer direct and meaningful expression, and both are quite straightforward in general. Germans are truthful in their speech. The confidence that reflects in their straightforwardness originates in their truthfulness. If they commit to someone, they do so by heart and mean it. They are not double faced people, unlike most of the people belonging to other nations. Their words are meaningful because Germans are very dutiful. Most Americans are also dutiful, though there is also a significant population in America that does not fulfill its commitments to others in various matters of daily life. Germans do not waste time. According to Germans, if a job is done correctly but has not been done within the assigned time, this goes against the work eth ics. German work ethics place huge emphasis on punctuality, and so do the Americans. Works cited: â€Å"Truth and Duty.† Culture Smart! Germany. pp. 41-42.

Will the European Union Survive? Essay -- European Union Essays

"Europe must prevent Greece from becoming an out-and-out catastrophe and make sure that the same fiscal 'remedy' is not applied to other weak economies" -- Franziska Brantner Europe is a powerhouse of Western culture and science. It possesses an economy with an annual Gross Domestic Product of over sixteen trillion dollars.1 Europe’s global economic connections are worth billions to developing countries and even the United States of America.2 Regrettably for the global economy, the European Union may collapse very soon, the cost of allowing incompetent politicians to run an economy on bad policy.3 A fiscal union is necessary to prevent the destruction of the Eurozone. The whole objective of the initiation of the European Union was to create a European economy, a greater European stability and society, all with a greater altruistic attitude.4 This may all have been for naught if the Europeans cannot adopt a preservative tendency. All sides of the table agree that a solution must be met. After all, to do nothing could risk the contagion of the primarily Greek, Portuguese, Spanish, and Italian crises to more internationally relevant economies, like France and Germany.5 However, the four most affected countries, Greece, Portugal, Italy, and Spain; known collectively under an umbrella pejorative â€Å"the PIGS†, already combine for 24.5% of the entire European economy.6 This means a loss of these states from the economy could already amount to sizeable damages. In spite of the potential for such a negative outcome, the sovereigns simply cannot agree to what this solution might look like, and all the solutions thus proposed have appeared to be unsatisfactory.7 Debt is a long term problem and accordingly, it makes sense to employ... ...Dec. 2011. . 14.

8051 Microcontroller Based

RF BASED REMOTE CONTROL INTODUCTION-: The Project Long Range Remote Control can be used to remotely control a number of Electrical or Electronic Gadgets connected to it. Unlike Infra Red remote control, this Project employs FM transmission and Reception, and hence it can be used for comparatively longer range. Any gadget can be switched on/off by keying the number allocated to it. The Receiver is made up of the famous 8 bit Microcontroller from Atmel. The Microcontroller is used as the Master in the receiver end which is used to control all the devices.It decodes the Signal from the transmitter and control the relays according to the signal. For transmission we are using frequency modulation at the frequency of 433. 92Mhz. A BRIEF INTRODUCTION TO 8051 MICROCONTROLLER-: When we have to learn about a new computer we have to familiarize about the machine capability we are using, and we can do it by studying the internal hardware design (devices architecture), and also to know about the size, number and the size of the registers.A microcontroller is a single chip that contains the processor (the CPU), non-volatile memory for the program (ROM or flash), volatile memory for input and output (RAM), a clock and an I/O control unit. Also called a â€Å"computer on a chip,† billions of microcontroller units (MCUs) are embedded each year in a myriad of products from toys to appliances to automobiles. For example, a single vehicle can use 70 or more microcontrollers. The following picture describes a general block diagram of microcontroller.AT89S52: The AT89S52 is a low-power, high-performance CMOS 8-bit microcontroller with 8K bytes of in-system programmable Flash memory. The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industry-standard 80C51 instruction set and pinout. The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional nonvolatile memory programmer. By combining a versatile 8-bit CPU with in-system programmable Flash on a monolithic chip, the Atmel AT89S52 is a powerful microcontroller, which provides a highly flexible and ost-effective solution to many, embedded control applications. The AT89S52 provides the following standard features: 8K bytes of Flash, 256 bytes of RAM, 32 I/O lines, Watchdog timer, two data pointers, three 16-bit timer/counters, a six-vector two-level interrupt architecture, a full duplex serial port, on-chip oscillator, and clock circuitry. In addition, the AT89S52 is designed with static logic for operation down to zero frequency and supports two software selectable power saving modes. The Idle Mode stops the CPU while allowing the RAM, timer/counters, serial port, and interrupt system to continue functioning.The Power-down mode saves the RAM con-tents but freezes the oscillator, disabling all other chip functions until the next interrupt The hardware is driven by a set of program instructions, or software. Once familiar with hardware and software, the user can then apply the microcontroller to the problems easily. The pin diagram of the 8051 shows all of the input/output pins unique to microcontrollers: The following are some of the capabilities of 8051 microcontroller. ? Internal ROM and RAM ? I/O ports with programmable pins ? Timers and counters ? Serial data communicationThe 8051 architecture consists of these specific features: ?16 bit PC &data pointer (DPTR) ?8 bit program status word (PSW) ?8 bit stack pointer (SP) ?Internal ROM 4k ?Internal RAM of 128 bytes. ?4 register banks, each containing 8 registers ?80 bits of general purpose data memory ?32 input/output pins arranged as four 8 bit ports: P0-P3 ? Two 16 bit timer/counters: T0-T1Two external and three internal interrupt sources Oscillator and clock circuits THEORY-: Radio Frequency remote control) A handheld, wireless device used to operate audio, video and other electronic equipment using radio frequency (RF) transmissi on.Unlike the more common infrared (IR) remotes, RF remotes do not require line of sight and do not have to be aimed at the equipment. In fact, RF remotes can be operated. RF Receivers (Base Stations) Are Required Since most equipment is IR based and comes with an IR sensor located on the front panel, the RF must wind up as IR. This is accomplished with an RF receiver, which is a base station and antenna, that accepts RF signals and converts them to IR. For use inside equipment cabinets, the receiver typically has an â€Å"IR blaster† that showers IR signals to all components by reflecting off the closed cabinet door.The RF receiver also has sockets for several IR emitters (IR flashers) that are wired to, and pasted directly over, the IR sensors in the equipment for precise aiming. See IR remote control and RF. References-: The 8051 microcontroller and Embedded systems using assembly and C Muhammad Ali Mazidi, Janice Gillespie Mazidi 1.
