Peter Paul Rubens free essay sample

The most sought-after painter in northern Europe during the seventeenth century, Peter Paul Rubens, was also a diplomat, linguist, and scholar. His dramatic artistic style of the seventeenth century is now called baroque, a term apparently derived at a later time from ornate jewelry set with irregular pearls. At its most exuberant, the baroque involves restless motion, startling color contrasts, and vivid clashes of light and shadow. Rubens was born in Siegen, Westphalia, to Jan Rubens and Maria Pypelincks. Born the son of a lawyer and educated at a Jesuit school in Antwerp, Flanders, Rubens learned classical and modern languages. He spent the years 1600 to 1608 studying and working in Italy. Returning to Antwerp, he continued to travel as both courtier and painter. His repeated visits to Madrid, Paris, and London allowed him to negotiate treaties while accepting royal commissions for art. One of Rubens major innovations in procedure, which many later artists have followed, was his use of small oil studies as compositional sketches for his large pictures and tapestry designs. We will write a custom essay sample on Peter Paul Rubens or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Rather than merely drawing, Rubens painted his modelli, or models, thereby establishing the color and lighting schemes and the distributions of shapes simultaneously. Rubens managed a very large studio in Antwerp, training many apprentices and employing independent colleagues to help execute specific projects. Among his mature collaborators whose baroque works are on view in the National Gallery of Art are Anthony van Dyck, Jacob Jordaens, Jan Brueghel, and Frans Snyders. Rubens style tremendously influenced baroque painters throughout Europe, even those such as the German-born Johann Liss who had no documented contact with the master. Liss The Satyr and the Peasant, for instance, is Rubensian in its lively gestures and telling expressions. Painted during the 1620s in Italy, it illustrates a tale from Aesops Fables in which an immortal satyr helped a peasant find his way through a winter storm. The goat-legged creature was astonished when the man put his chilled hands to his mouth to warm them. In thanks for the satyrs guidance, the peasant invited him home to eat. The satyr was further perplexed when the man blew on his spoon to cool the hot soup. The satyr jumped up in disgust at human hypocrisy, proclaiming, I will have nothing to do with someone who blows hot and cold with the same breath! The Fall of Man Rubens copied many of Titians paintings. Part of Rubens greatness was due to his eager study of earlier masters and his ability to combine their techniques with his own style. The Fall of Man is an interesting example of a work after Titian, that is very close to the original but in which Rubens has changed some details. The red parrot in the tree is not in Titians painting. The colors in Rubens painting are more yellowish and Rubens has actually improved Titians painting by giving Adam a more natural pose. In fact, Adam looks a lot like Rubens himself. When Rubens made this painting, he had just met his second wife-to-be, Helene Fourment. She was only 15 years old at the time. Adoration of the Magi Religious paintings were fashionable during the time of Peter Paul Rubens and were nearly always reverential. Adoration of the Magi is a good example of how Jesus was expected to be venerated in art. A painting of 99 inches by 133 inches, Adoration of the Magi is an oil on canvas painting that features a group of figures, who are waiting in turn to pay homage to the newly born Jesus. It is painting that was created by Rubens in 1616 and 1617. The Power of Christ The Virgin Mary is depicted holding up Jesus as an elderly magus kisses the babys feet. Rubens clearly shows that Jesus is no normal child, as quite apart from the large group of people who have come to see Christ, the infant Jesus is seen touching the head of the elderly magus as a sign of acknowledgment of the old mans devotion. Rubens also adds power to the image and of Jesus himself, with the ethnic mix of the visitors. This suggests that the men have traveled from many different parts of the world to witness seeing the baby Jesus and are not all, in fact, magi. The age of the men and the way they are dressed indicates men of power, and, consequently, their humble adoration of Christ gives the work an added weight. Though the expression of the figures in the painting are almost universally serious, there is one man who appears to be smiling and acts in a way many adults would normally act on seeing a baby. The Virgin Mary, however, looks very serious, almost severe, but she is concentrating on Jesus not coming to any harm, as he is standing upright to receive the line of visitors. The Propaganda Element As with most religious paintings of the early 17th Century there could be said to be an element of propaganda in Adoration of the Magi, as it is really showing the power of the Church. It is painting that is saying that however powerful leaders may be, the Church is more powerful than any earthly empire. The fact that there is little light in the painting gives it an air of mystery, as one wonders if some figures are deliberately hidden. Some of the visitors to the stable are also partly hidden by other visitors. The horse to the left of the painting infers that animals are also part of the kingdom of God. Adoration of the Magi currently hangs in the Musee des Beaux-Arts, Lyon, France. VENUS IN FRONT OF THE MIRROR Peter Paul Rubens presented his Venus in Front of the Mirror as the ultimate symbol of beauty. She is aware of the viewer in a mirror that frames her face like a portrait. Great play is made of the sensual reproduction of her skin and silky hair, which is further enlivened by the contrast with the dark-skinned maidservant. The few costly accessories, otherwise decorative additions to elaborate clothing, emphasize the figure’s nakedness. The sensual qualities of the painting are created by Rubens’s subtle painterly approach. He alternates sketchy brushstrokes, drawn over the ground like a transparent veil, with compact areas, painted in great detail. One particularly attractive feature of the picture is the contrast between the goddess’s encounter with the viewer, which seems to occur almost by chance, and the representation of her beauty, as if conceived for a spectator. The mirror that Cupid holds up for the goddess reveals an additional level of meaning: the reflection of Venus, which reveals her beauty to the viewer, becomes a symbol of painting that competes with nature to produce an image that is as real as possible.

Explanations of Schizophrenia Essays

Explanations of Schizophrenia Essays Explanations of Schizophrenia Essay Explanations of Schizophrenia Essay Describe two explanations of schizophrenia and evaluate these explanations (9 and 16 marks) Two explanations of schizophrenia are the biological perspective and the psychological perspective. The biological perspective involves genetic factors that influence schizophrenia, however the psychological perspective involves environmental factors in which you learn the behaviour of a schizophrenic. The first explanation is the biological perspective, it has two subtypes, these are biochemical and genetic. The biochemical type talks about enlarged ventricles in the brain, these are cavities that supply nutrients and remove waste. The reason for enlarged ventricles could be due to an issue with diet. It also talks about the dopamine hypothesis, this is excess neurotransmitters. Dopamine occurs in the limbic system, this plays a major role in regulating emotional and sexual behaviour, attention and thoughts. Amphetamine and cocaine both largely increase levels of dopamine and can cause psychosis, this can sometimes explain attention and thought problems in schizophrenia as the dopamine neurons play a large role in guiding a person’s attention. Anti-psychotic drugs like chlorpromazine are thought to work by binding to dopamine receptor sites. The genetic type goes on to talk about how schizophrenia is found more in biological relatives depending on how close the family link is. Monozygotic twins have a 44. 37% of being born with schizophrenia. The PPP3CC chemical is an enzyme which regulates the immune system; it appears to be defective in many patients diagnosed with schizophrenia. The second explanation is the psychological perspective; there are many different explanations for schizophrenia that take a psychological view. These contain psychodynamic, cognitive, behavioural and other socio-cultural factors like the role of family and society. Cognitive explanations acknowledge the role that schizophrenia is characterised by thought disturbance. This could be down to cognitive deficits which can weaken areas such as perception and memory. Schizophrenics usually first discover symptoms of voices and abnormal sensory experiences, this then usually makes them turn to friends and family to confirm the experiences. Then other symptoms such as hallucinations and delusions are formed after the failure to not accept the reality, these of which are cognitive. The behavioural explanation suggests that schizophrenia is a consequence of faulty learning. Children who do not receive small amounts or little reinforcement early in their lives will put larger attention into irrelevant environmental cues. This behaviour will eventually appear ‘weird’ or strange to others and so will generally be avoided. These strange behaviours may be rewarded by attention and sympathy and so they are reinforced. This can continue until the behaviour becomes so strange that they are then labelled as schizophrenic. The psychodynamic explanation was developed by Stephen Freud. In terms of schizophrenia he suggests that the health condition is a result of regression to a pre-ego state and attempts to re-establish ego control. If the life experiences of a schizophrenic are harsh then the person may go back to a stage of development before the ego and awareness of the world is properly formed. Symptoms such as delusions can reflect this basic condition and other symptoms such as hallucinations and voices reflect the attempts of the person trying to re-establish its ego control. Socio-cultural explanations stress the role of social and family relationships. This can include social labelling, family relationships and life events. The family relationship theory suggests that children who frequently receive contradictory messages from their parents are more likely to develop schizophrenia. This will lead the child to receiving confused and conflicting messages about their relationship, conflict between verbal and non-verbal. Chronically this can develop into schizophrenic symptoms such as delusions and hallucinations. One strength of the biological explanation is that it has high reliability. The reason for this is because the research is carried out in highly controlled environments. This suggests that if this research was tested and re-tested the same results would be achieved. Another strength is that it has practical applications. However, a weakness of the biological explanation is that it lacks population validity. The reason for this is because the samples that are used are too small in numbers and only a select number are actually used. This suggests that there are issues with the findings being generalised to the whole population. Another weakness is that it is reductionist and too over simplistic. Also, is the raised dopamine levels the cause of the schizophrenia, or is it the raised dopamine levels which are the result of schizophrenia? It is not clear which comes first. This suggests that one needs to be careful when establishing cause and effect relationships in schizophrenic patients. One trength of the psychological explanation is that it has practical applications. Another strength is that it takes on board the nurture approach to the development of schizophrenia. For example, it suggests that schizophrenic behaviour is caused by environmental factors such as cognitive factors. However, a weakness of the psychological explanation is that you cannot determine cause and effect. Another weakness is that there are ethical issues in blaming the family, particularly as there is little evidence in which to base thi s. Gender bias is also an issue as the mother tends to be blamed the most. This suggests that the research therefore does not protect individuals from harm. Another weakness is that it can said to be reductionist. The reason for this is because the approach does not consider other factors such as genes. It could be that the problems are caused by low neurotransmitters and that creates the cognitive deficits. This suggests that the cognitive approach is over simplistic when considering the explanation of schizophrenia.

Critically evaluate, in relation to the common law duty of care, the Essay - 7

Critically evaluate, in relation to the common law duty of care, the liability of employers for references. How, if at all, doe - Essay Example Selective provision of reference for former employees could contravene the Equality Act 2010 (the Act) if such an exercise amounts to discrimination. In cases where an employer does not offer a reference, it is bound by a duty of care to the former employee. The duty requires the former employer to exercise reasonable care in the processing of accurate, truthful, clear, and fair references (Sam, 2004). Employers also have a duty to fellow employer. In executing this duty, Austen-Baker (2011) notes that a former employer may offer a detailed or a brief reference; however, the content must contain all the necessary information that leaves no room for speculation. Any employer who fails on this may be liable for negligent misrepresentation of facts (Gergen, 2013). Such an employer may also be vulnerable to tort of deceit charges. Detrimental treatment The Act provides important safeguards against victimisation of an individual who files a case against a former employer or has volunteere d evidence in trial under the statute or filed a claim for violation of the statute (Elder, and Gerdes, 2007). Before the Act was enacted, the English common law had ensured that immunity against whistle-blowers and victims was in place. For instance, the House of Lords verdict in the case of Rhys-Harper v Relaxation Group plc [2003] IRLR 484, directed that employees should be cushioned against victimisation such as an employer’s denial of reference in connection to an earlier engagement. Marson (2013) has pointed out that Section 108 of the statute precisely leaves out issues to do with detrimental treatment where an employer-employee relationship has ended. Even though the motive behind Parliament’s decision to leave out victimisation claims after the end of an employment relationship could be seen as an error, the alleged gap is consistent with placing no duty on an employer to give reference to a former employee. Authorities Various examples of the UK case law have not been consistent on victimization of former employees. In the case of Ono v Akwiku (2012), the Employment Appeal Tribunal (EAT) issued a verdict to the effect that it is legal for ex-employees to file for a claim for detrimental treatment under the Equality Act 2010. The ruling may have been informed by the fact that some employees are victims of unfair dismissal and subsequent victimization. Regardless of the reasoning, the EAT verdict contradicts the outcomes of the case of Rowstock Ltd & another v Jessemey (2013). In the latter case, the EAT held that Mr Rowstock could not be remedied for victimisation, following his receipt of a bad reference from his ex-employer. The claimant had alleged age discrimination as victimisation (Marson, 2013). The EAT's ruling was informed by the literal rule of  §108 of the Act, which could not be construed to arrive at a different meaning (Gergen, 2013). In the case of Ono v Atwiku, the petitioner, a domestic employee filed for a claim again st her ex-employers citing detrimental treatment which happened after the engagement between the two parties had ended. In its decision, as Marson (2013) states, the EAT sought to correct the ruling in Jessemey, by arguing that it would not be proper to bring claims of victimization against the former employer after they had gone separate ways. Legal absurdity In spite of the correction of the ruling on the former case

Personal journal Essay Example | Topics and Well Written Essays - 250 words - 2

Personal journal - Essay Example My best friend and his dad had also joined us. We all rose up early the morning of the long trip up to the camp site. Mom had made a whopping helping of pancakes and packed our lunches for along the way. My friend and I couldn’t sit still and hurriedly gulped down our breakfast forcing our dads to hurry up as well. Finally we headed out and I remember counting the cars to make the hours go by faster. When we arrived at the site, it was just like how my young mind hand imagined it. The clearing was wide and beautiful surrounded by trees, shrubs, and swaying grass. We had immediately set up the tents and started collecting logs for the campfire before the sun went down. There was a small stream not far away where we planned to do some fishing the next day. It was the perfect spot for the perfect weekend. That day we just rested and lay by the water, dipping our feet lazily, staring up at the darkening sky. The stars I remember seemed super bright and closer than usual. We had go ne to sleep early, resting up for the busy two days ahead. The next day we rose bright and early, ready to go hiking and later fishing for our lunch. At night the four of us used to sit around on logs with a flaming, hot camp fire in the middle, holding out our sticks covered in layers of gooey marshmallows. My friend’s dad told the best scary stories.

Counting rationally to 15 Essay Example | Topics and Well Written Essays - 500 words

Counting rationally to 15 - Essay Example Blocks of wood can be labeled 1 - 15. Cups can then be placed on top of these blocks. The rule of the game would be, one cup on top of each block. To evaluate mastery on one to one correspondence, the teacher can post fifteen pictures on the board and indulge the students in yet another game. The teacher will then count the pictures on the board and the student that catches the teacher doing an erroneous counting gets an extra point. One such error by the teacher would be counting the same picture twice. Geary (1999) tells us that although children with MD understand one to one correspondence, they sometimes make mistakes on tasks that assess this concept. Children with mathematical disabilities(MD) almost always detect double counting when it is the last manipulative that is counted twice. When the first manipulative is double counted, the child has to wait until the counting is finished before he can decide whether the counting was erroneous or not. This suggests that children with MD have difficulty keeping information while counting. To solve this problem, have them use their fingers to count (Brown, Ferguson and Witzel, 2 007). This helps them associate counting with their fingers (one finger for '1', two fingers for '2' and they may use sticks as substitutes for numbers '11' through '15'). They can then keep track of the manipulatives as they count them. Stable order. The order of the word tags must be invariant across counted sets.

Gunshot Forensic Analysis

Gunshot Forensic Analysis School of Chemistry MM4EOX: Electron-optical and X-ray Techniques Pages 12: Forensic investigation: trace evidence analysis for gun-shot residue Page 3: Phase identification : characterization of nanostructured materials Page 4: Enviromental safety: characterization of fine scale particle distribution Forensic investigation: trace evidence analysis for gun-shot residue Introduction The ability to identify gunshot residue has provided solution to the problems encountered in the resolution of forensic science, legal medicines, and for shooting distance determination. Visually comparing the casework powder residue pattern on the garment or on the skin of the victim with the pattern obtained from a series of test firings at known distances, using the same gun and ammunition has been used as a method for routinely estimating gunshot range. Burned and unburned powder grains, carbonaceous particles, bullet jacket debris, shaving and dirt have been shown to be examples of materials ejected from the bore of the weapon around the entrance hole of the bullet and have been used as materials for analytical determination in order to obtain a more and accurate result.1 An issue that has become very important in criminal investigation is trace evidence. Very often it come into place after the commission of a crime, well after the charges have been filed and well after the completion of forensic examination. Trace evidence can usually take the form of fibers, paint chips, soil, building materials, glass, gunshot residue, seeds, feathers, animal hair, human hair, wood fragments and other material. It has been proved that these substances are usually transferred between individuals during physical contacts and can also be transferred from individuals to environments and from environment to individuals.2 This report shows how complementary analytical techniques ranging from batch injection analysis (BIA) method, based on differential pulse anodic stripping voltammetry (DPASV), scanning electron microscopy/ energy dispersive X-ray analysis (SEM/EDX), capillary electrophoresis, can been used to identify trace evidence for gun-shot residue. Batch Injection Analysis Batch injection analysis (BIA) method, based on differential pulse anodic stripping voltammetry (DPASV) can been use to carry out forensic analysis of lead in gunshot residues (GSR). The design consist of a simple â€Å"J† shaped adaptor which is being used to direct the flux of the analyte injected with a micropipettor onto the hanging mercury drop electrode of any commercial electrode stand. Lifting with adhesive tape is usually selected for field use and pasting of the tape is done on polyethylene screens and stored in capped vials. Sampling is usually done with multiple strips and thus provides coarse mapping of the distribution of the Lead on the shooters hand following the dissolution/extraction step with chloroform/aqueous HCl. Certain volume of this aqueous phase is then injected for few seconds for accumulation of the Lead on the HMDE at a certain volt (vs. Ag/AgCl). A detection limit of 20 ng/mL of Pb(II), outreaching for GSR analysis can be achieved without oxygen r emoval, at a frequency of 20 injections per hour. Quantitative analysis has shown the detection of over 90% of lead residues.3 Scanning electron microscopy/ energy dispersive X-ray analysis Elemental analysis using SEM/EDX can be carried out in order to understand bullet structure and major elemental composition. Datas produced from elemental composition of bullets can be used in deciding the exact methods most appropriate for the identification of bullet hole and the determination of firing distance. Bullets and shots are usually collected from unfired cartridges and subsequently brushed with detergents and cleaned using tap water, distilled water, and acetone. Double-sided carbon tape can be used as a means of mounting jackets, lead cores and lead bullets and shot onto the sample stub on subjection to SEM/EDX analysis. The external surface, cross section of lead core, lead bullet, or lead shot can be subjected to elemental analysis using EDX. The internal surface and cross section of the jacket can also be subjected to elemental analysis in order to understand its structural composition. EDX measurement conditions can be set from the SEM unit with regards to spectral measurement, multi-point measurement, mapping, and display of analysed elements on the SEM monitor. The image data obtained from the SEM can be used as basic data for the EDX, while the setting conditions for the SEM units are automatically transferred to the EDX unit. The function which provides the strongest backup for elemental distribution is the Smart Map. The Smart Map operates by recording the X-ray spectral data for all analysis points on the test sample together with the positions of analysis, thus providing the user to recall valuable data as needed. Backscattered electron imaging mode in SEM is able to reveal layers of metals on the jackets cross-section and its subsequent compositions while on the other hand, EDX analysis is able to reveal the coating elements detected on the external surface of lead bullet.4-5 At the moment, this technique is widely accepted due to the morphological (SEM) and elemental (EDX) determination of the metal residue. Capillary electrophoresis Capillary electrophoresis can be used for the analysis of organic and inorganic components of gunshot residue in order to study sampling methodology, selectivity, reproducibility, quantification and the enhancement of the bulk analysis. A typical P/ACE MDQ Beckman capillary electrophoresis system is being used with polymide bare fused silica capillaries. A diode detector is usually used as a means of carrying out direct UV detection. A temperature of 25oC, with a positive voltage of 30KV and hydrodynamic injection of 5s and 0.5 p.s.i is usually used. The conditioning of new capillaries is usually done by rinsing with ethanol, HCL, NaOH at specific time and temperature. Between runs, the capillary is usually rinsed with deionised water, NaOH, and again with deionised water and background electrolyte at specific times. The sample is usually ejected into the capillary by temporal replacement of one of the buffer reservoir (usually at the anode) with a sample reservoir upon application o f either an electric potential or external pressure for a few seconds. Upon replacement of the buffer reservoir, an electric potential is applied between the capillary and the separation is performed. Optical UV-detection of the separated GSR component can be obtained directly through the capillary wall near the opposite end (usually near the cathode). Swabbing technique has been used as a means of obtaining samples from gunshot. This technique is however not too good in detecting important organic residue such as barium and antimony. Figure 1, shows a typical zone of sampling for gunshot residue.6-7 Figure1 Typical zones of sampling for gunshot residue. (A) web and (B) palm.7 Phase identification: characterization of nanostructured materials Complementary analytical techniques such as X-ray diffraction (XRD), electron microscopies such as TEM SEM, and EDX spectrometry can be employed as a set of tools in characterizing a one-dimensional inorganic nanostructure in order to investigate the crystal structure, particle size distribution, morphology, composition and aggregate state. XRD The technique of XRD can be used to deduce the lattice parameter of inorganic nanostructures which can be used to provide information on the thermal properties of the material, strain state or an analysis of the defect structure. The diffraction pattern of the material can be indexed appropriately if the crystal structure of the material is known. For example, in a cubic system, the d spacing which correspond to each diffraction pattern is related to the lattice parameter a following the equation a2 = d2 / (h2 + k2 + l2) in which hkl are the miller indices. This is however used in indexing the diffraction pattern. This technique is however subject to systematic error in the position of the diffraction peaks and random error in the individual calculation of the lattice materials.8 The calculated lattice parameter value is usually compared with the experimental value and this can further be used for appropriate interpretation of result. SEM/EDX Nanostructured materials can be characterized by SEM integrated with an EDX analyzer in order to determine the particle morphology and chemical composition of the sample. The SEM column forms a focused probe of electrons on the sample while the beam current and probe current are usually adjusted as required. An image is formed by scanning the probe in a raster pattern on the sample, detecting some excited radiations from the sample, and storing the result either as a pattern of varying intensity levels on a cathode ray tube (CRT) screen or an a pattern of digital values in electronic memory for later manipulation and display. SEM images are usually formed by detecting either the secondary (low-energy) electrons emitted from the sample, or the backscattered (high-energy) electrons.9 Secondary electron images can provide information on the sample topography thus revealing information about the grain size distribution of the material. TEM/EDX TEM/EDX investigation of nanostructured materials can provide a more detailed information about the smallest particle. When the selection area diffraction (SAD) pattern is projected onto the viewing screen, we can use this pattern to perform the two most basic imaging operations in the TEM. In order to form an image in TEM, we either use the central spot, or we use some or all of the scattered electrons. The way we choose which electron forms the image is to insert an aperture into the back focal plane of the objective lens, thus blocking out most of the diffraction pattern except that which is visible through the aperture. If the direct beam is selected the resultant image is a bright-field (BF) image and if the scattered electrons are selected then the resultant image is the dark-field (DF) image.10 The dark-field imaging and digitization of particles can be used to extract size distribution of the grains through thresholding and measurement of the projected areas. Enviromental safety: characterization of fine scale particle distributions Appraisal of the fine scale particle distributions emitted from a waste disposal furnace can be carried out using SEM/EDX to investigate the particle morphology, composition and chemistry, while TEM/EDX can be carried out to give a more detailed information about the particle size distribution and SIMS to determine isotopic ratios. SEM/EDX SEM equipped with an energy dispersive X-ray (EDX) spectrometer can be used determine the elemental composition, morphology and chemistry of emitted particle in a waste disposal furnace. In order to determine the emitted particle containing the heavy metals, the sample is subjected to backscattered electron imaging while emitted particle containing salts can be imaged in the secondary electron mode. The detected backscattered electrons originate from the larger volume of the sample than do secondary electrons, and thus form an image of lower resolution. Focusing of a small spot on the high Z area followed by analysis of the X-ray signal with EDX allows the resulting X-ray lines to be detected and the elemental composition determined. TEM/EDX TEM images of the sample which comprises DF and BF can be coupled with EDX analysis and chemical mapping can be carried out. Both DF and BF imaging in TEM can be used to investigate the metal speciation in the fine fraction of the emitted particle furnace. DF imaging and digitization of the particle can be used to extract size distribution through thresholding and measurement of project areas. Elemental composition of the emitted particle could be detected in small aggregates upon analysis by EDX and selected area electron diffraction. SIMS Secondary ion mass spectrometry (SIMS) can be used to determine isotopic ratios of the heavy metals from within emitted particles. It operates by switching between masses and it possesses two microfocus ion sources. Sputtering is usually done with a primary O2+ and the intensity controlled by tuning the primary ion beam. The instrument can operate with a mass resolution power (MRP) of 25000.11 REFERENCES [1] Roberto G, Anna P and Salvatore, J Forensic Sci, March 2008, Vol. 53, No. 2.

A Critical Look at Histories of Hutchinson and the Antinomians Essay

A Critical Look at Histories of Hutchinson and the Antinomians In the seventeenth century, the Massachusetts Bay Colony was founded as a haven for Puritans, who sought religious freedom and harmony. In order to achieve this haven, the settlers in Massachusetts Bay devised a system of government that would serve as both a political and moral authority. Between 1636 and 1638 the relative harmony of the Massachusetts Bay Colony was shaken by an uprising that has become known as the Antinomian Controversy. At the center of this controversy was Anne Hutchinson, a Boston woman bold enough to challenge the teachings of local ministers and to criticize New England churches. Hutchinson was extraordinary for a variety of reasons. Her theology of â€Å"free grace† and her claim to have received immediate revelations from God were considered a dangerous deviation from Puritan theology. She was also a woman challenging the established male hierarchy of Puritan society. In addition, her theological ideas had important implications fo r political theory and attracted many followers in seventeenth-century New England. However, despite all that is known about Hutchinson’s life and the details of the Antinomian Controversy, there are no written records of her beliefs. Instead, contemporary historians, political scientists and feminists must interpret her actions, trial records and the accounts of her contemporaries to determine why she chose to challenge Puritan society in the way that she did. Because little is known about why Anne Hutchinson acted as she did, she has become a veritable chalice into which historians, political scientists and feminists can pour their own ideas. As a result, interpretations of Ann... ...6. Hall, David D. The Antinomian Controversy 1636-1638: A Documentary History. Connecticut: Wesleyan University Press, 1968.

Online vs Classroom Education Essay

Online vs. Classroom, which format is better for you? Well that all depends on you as a student and what fits your lifestyle. They say that college students between the ages of 18-21, benefit more from attending a traditional college. They have more of a need for the social atmosphere, plus this means freedom from living at home. Students who are older most likely already have jobs and family to support. Therefore, they find that going to an online university or college fits their lifestyle better. In the following pages, I am going to discuss the differences between online and on-campus classes and how internet classes compare to face-to-face classroom settings. Being in the classroom provides an interactive setting. Having students all in the same classroom has the benefit of allowing students to exchange ideas and have discussions with the teacher included in the exchange without any communication barrier. I just recently graduated from a Summit Career College and there’s no way I would have gotten through learning all the Microsoft Office Applications if I wouldn’t have taken it in class and had fellow student’s, plus my teacher there in class to help me. Therefore, you need to think about what kind of student you are and what kind of education program you will need to get through the subjects you are taking. Online learning provides a different level of conversation between students and with their teacher. They interact through class discussion boards, e-mail, and student chat rooms. Student chat rooms make it easier for professors to be more readily available to students. In addition, you have the opportunity to meet people from other parts of the world. For instance, I have had fellow classmates that are over in Iraq taking the same classes. Which I have found to be amazing on their part and informative. Since I have started at Ashford University, I look forward to the discussion boards and getting feedback from my classmates through that of communicating. Classrooms tend to group students together in large numbers, which makes it easier for students with learning deficiencies to get lost in the shuffle. In addition, for students who are shy or reserved to speak up in class and taking part in class. I have experienced that first hand at my last college. I found that most of the students in class did not respond to the teacher’s questions for fear of getting it wrong and feeling embarrassed when they did. Online classes have more of a one on one perspective from the teacher’s standpoint. Because most of the teacher to student communication is through e-mail, discussion boards or student chat rooms. Therefore, for some students, that is less intimidating and they do not have to worry about the teacher calling on them. . With online classes, students that are shy or reserved are not afraid to speak up or taking part in discussions. Online education requires discipline, focus, dedication, and motivation as does on-campus. There are so many distractions when you are at home then when you are in class. When you are at home, you can pick the place and time that is best for you to do your study time. In addition, if you have a full time job to go to everyday, online classes make it easier for you to get your education that way. In class, you have a teacher in front of you to keep you focused and to help you pay attention. Online you have to keep yourself focused, you are responsible f or getting your assignments, and making sure, they are turned in on time. In class, you have more reminders around you for getting your assignments in on time and there is more structure. In conclusion, there are many advantages and disadvantages to either type of learning environment. It is to your advantage to use something from each method to its fullest. The combination of both online and classroom education might be what is best for some students. However, for some students having a consistent school schedule prohibits some students from furthering their education. It is up to the student to figure out which is better overall for them. So, do your research on which schools have and which format is right for you. I did about a month of research on online schools before I picked Ashford University. I would recommend you do your homework before you select a school for yourself.

Buffalo Soliders In The West essays

Buffalo Soliders In The West essays Throughout American history, African Americans havent had too much say in whether or not they belonged in the United States or not. Slavery without a doubt had a great impact upon their decisions. However, despite their troubles, African Americans have paid their dues and have made an impact on our armed forces since the Revolutionary War. African Americans have fought to preserve the rights for Americans, as well as having to fight the war within their very own country to gain the right to fight for their country and their individual freedom. Approximately sixteen months after the end of the Civil War, an Act of Congress entitled the Buffalo Soldiers An Act to increase and fix the Military Peace Establishment of the United States. Which authorized the formation of tow regiments of cavalry to be composed of colored men. This act was approved on July 28th, 1866. On September 21st, 1866, the 9th cavalry regiment was activated in Greenville, LA, along with the 10th cavalry regiment, which was activated at Fort Leavenworth, KS. Even though the African American soldiers clearly distinguished themselves as soldiers, they were by no means wanted in the army. Shortly after General Washington took command of the Army, the white colonists decided that not only should no black slaves or freemen be enlisted, but that those already serving in the Army should be dismissed. The colonists didnt enjoy the black soldiers in the army because they felt that blacks werent smart enough and as well trained to handle themselves in battle. In turn, would only be taking up space and food for the other soldiers who they felt were more equipped to fight with the army in major battles. The colonists would probably have kept Blacks out of the military during the war if it were not for the proclamation by the Lord of Dunmore. His statement was, "I do hereby... declare all... Negroes... free, that are able and willing to bear ...

John Calhoun essays

John Calhoun essays John Caldwell Calhoun was born in 1782 in South Carolina. Calhoun was born near Abbeville District, South Carolina, and was an honors graduate at Yale College in 1804. He practiced law in Abbeville District until his election to the South Carolina legislature in 1808. He was a major American political figure before the Civil War. Calhoun played an important part in national affairs for 40 years. He was Vice President of the United States from 1825 to 1832, and he ran for President several times but never won. He also served as a member of the U.S. House of Representatives and of the Senate, and as secretary of war and secretary of state. Calhoun is best known for his doctrine of states' rights, in which he claimed that each U.S. state had a right to reject national laws. He wanted to use the doctrine to protect slavery and other Southern interests without requiring the Southern States to withdraw from the Union. Later, however, the doctrine helped bring on the Civil War 1861-1865. Calhoun entered national politics as a member of the House of Representatives from 1811 to 1817. He was a fiery nationalist, and together with other young congressmen he was called a War Hawk for advocating the War of 1812. He actively supported the government's postwar program, which included a protective tariff, a national bank, and an enlarged army and navy. He improved the army's organization while secretary of war from 1817 to 1825. Calhoun was the vice presidential running mate of both Andrew Jackson and John Quincy Adams in 1824. He won by a landslide, but the vote for President was uncertain. The House of Representatives picked Adams. In 1828, Jackson again opposed Adams for President, and Calhoun served as Jackson's vice presidential running mate. Jackson and Calhoun won the election. But after Jackson became President, the two men quarreled, especially over Calhoun's support of nullification. Calhoun felt th ...

Pulmonary Effects Of Smoking Marijuana Dissertation

Pulmonary Effects Of Smoking Marijuana - Dissertation Example Research shows that many users of marijuana often inhale it as extremely hot fumes, usually to peak inspiration, and held as long as possible before being exhaled slowly. According to a study by Forrester et al (2012), this form of smoking has a greater impact on the pulmonary system because it predisposes the lung parenchyma to a greater damage than the smoking of standard tobacco cigarettes. Research concerning the impacts of smoking marijuana has been done in the past and confirmed that the risk of regular smoking of marijuana is similar to those of regular tobacco smoking (Onaivi, 2006). There are many studies on the effects of tobacco on the respiratory system as well as certain diseases have been profiled and linked to tobacco. However, few studies have focused on the effect of marijuana on the pulmonary function. Hii et al (2008) investigated the effects of smoking marijuana upon pulmonary emphysema using a series of 10 patients consisting of ages between 32 and 50, two female and eight male. The participants were those who were presented over a period of 12 months in a respiratory unit showing new respiratory symptoms and those who admitted being regular consumers of marijuana. The participants also exhibited the following symptoms on presentation including dyspnoea, pneumothorax and any kind of chest infection. In this study, high-resolution CT shows variable sized, asymmetrical emphysematous bullae in the mid and upper zones. However, CT revealed normal CXR in four patients and normal functioning of the lung was normal in five patients. This study shows that marijuana smoking predisposes individual smokers to asymmetrical bullous disease mostly in normal CXR setting and function of the lung. The study also revealed that these pathological changes take place at a younger age up to 2o years earlier compared to tobacco smokers (Hii et al, 2008).

Some Abortions are Immoral and Some are Moral Essay

Some Abortions are Immoral and Some are Moral - Essay Example The debate on 'Why would a mother choose to end her own child's life' is never ending. There are various moral, ethical, health and legal issues involved. Abortion not only effects mother and her baby but also the rest of the family members: father, siblings of baby, grandparents, friends and everyone else involved in the process. 1. Measure of birth control: 98% of abortions result as a measure of birth control. It is the leading cause of death in America. Since no birth control method is 100% effective, women opt for a termination in case of an unplanned pregnancy ("Abortion 101,"n.d.). 2. Teenage Pregnancy: One of the major reasons of teenage pregnancy is unawareness. Most of these pregnancies are unintended resulting from unsafe sex. Teens choose abortion as they are not prepared to become parents at such an early age of life. In 1999, over 148,000 teenage pregnancies ended in abortion. Most of the abortions are performed without the consent and knowledge of parents. The best measure to prevent the teenage pregnancy is the education about safe sex and support of parents (Alford, 2003). 3. Rape and incest: Rape and incest victims account for 1% of the abortion cases ("Abortion 101,"n.d.).Abortion is often seen as a solution to the problem. But it can have serious long lasting effects on the mother such as depression, guilt, anger, loneliness. (Reardon, 1994). 4. Single parenting: In many cases, woman's partner may not support her in pregnancy and wants to go ahead with the abortion. This leaves mother in dilemma to choose birth or abortion. Understanding the problems faced by single mothers in the society, mother may opt for an abortion ("Why Do Women Have Abortions," 2006). 5. Financial issues: Some mothers consider that they are not financially sound to support their child after birth. This situation may lead to inadequacy of indispensable resources in upbringing of the child. The future and security of both the mother and the child are at risk. Most of the times this situation is due to single parenting ("Why Do Women Have Abortions," 2006). 6. Pregnancy due to a dishonest premarital or extramarital relationship: Pregnancy resulting from an illicit relation may ruin a women's family and social life. It may have serious impact on other family members such as her husband, other children, in laws and friends. 7. Pregnancy as a hurdle in education and career: College age women form the major abortion carrying group. Pregnancy is seen as hurdle in realizing their dreams. 8. Gender selection: It is also a major cause of abortions, especially in Asian countries like India and China. Families who do not have enough funds to raise and educate many children, opt for sons who will eventually earn for the family in future and abort girl child with the fear of raising her to be married into someone's else's home. 9. Domestic violence issues: Women subjected to domestic violence in their families do not want to give birth and raise their babies in such an environment and choose an abortion over birth. 10. Birth defects detected in the babies: If the medical tests detect birth defects in the babies, mothers can opt
