Cultural Lag free essay sample

Myriad new technologies that have developed in the decade of the 1990’s have been the focus of debate regarding ethical guidelines for their application. From concerns over worker surveillance to the security of banking transactions, and pornography on the internet to artificial insemination, technological advances have stirred public controversy. This recent issue on gender selection by using pre-implantation genetic diagnosis has reflecting on the technological shifts from the past thirty years.From the very beginning, we take baby as the special gift from the God, whatever happened to the baby, we accept and appreciate; for now, with the new and high-technology, we greedy about the gift, we want to decide what kind of gift to take from the God. What does it means for our traditional ideas and values about motherhood and fatherhood? Is this result from gender selection baby, the ‘natural gift’ from the God? When these questions arise, there is cultural lag. We will write a custom essay sample on Cultural Lag or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page According to William Ogburn (1957), cultural lag occurs when the tendency of  material culture  evolve and change speedily and voluminously while non-material culture tends to resist change and remain fixed for longer period of time. Material culture is just what it sounds like: ‘food, furniture, building and other group of things. ’ Central to a group’s material culture is its technology (Weber, 2000). When this material culture changes, the non-material cultures, which includes norm, value, beliefs, practice, mores and folkway must change in response change in response.Adaptive culture comprises the portion of nonmaterial culture that adjusts to material conditions. It always takes a while for the adaptations to catch up with material changes, and this gap is the â€Å"cultural lag† (Ogburn, 1957). The extent of this  lag  will vary according to the nature of the cultural  material, but may exist for a considerable number of years, during which time there may be said to be maladjustment (Ogburn, 1966). Another pending moral question for reproductive medicine is what to do with the many thousands of embryos created for couples, but no longer needed by them.

American Expansion essays

American Expansion essays American expansion to the Pacific was introduced to the people of the country by several different means. The reasons for expansion did not exclude Politics, economy, nor society. Primarily the contributions that that the rise of expansion can be attributed to include Manifest Destiny, land hunger, suspicion of British intentions as well as trade opportunities. Each was valuable, some more than others, to impel the wheels of expansionism to begin. The most important contributor to American expansion is Manifest Destiny. This term, developed by an American journalist basically state that America had a divine ( god-given) right to extend its power and civilization across the width of the North American continent. Perhaps it was the scattered missionaries in the Northwest, along with the introduction of Manifest Destiny made the idea of traveling thousands of miles, was, in fact worthwhile. Manifest Destiny was so important of an issue that the election and campaign of 1844. The Democrats were swayed by the idea and part of their campaign was that they should uplift their ennobling democratic institutions over the expanse of North America. The idea of God giving the population the right to expand their society could be accepted by God-fearing Christians, of which, most of the population was. They all could understand the idea of Manifest Destiny because it dealt with God, not property, wealth or social standing. It was an is sue that could allow people of all backgrounds to prosper. Land hunger was the second most important contributor to expansion. The land out in this wide open, western unknown was free! People wanted land because at this time land equaled wealth, and people who were not wealthy, could not buy land. This first come, first serve style allowed the people who were hungry for land to obtain it, even if they did not have the means by which to buy any land back east. This way they could even make a profi...

Subliminal Messages Essays

Subliminal Messages Essays Subliminal Messages Paper Subliminal Messages Paper After reading the article, what hypothesis do you think the researchers were testing in this study? Looking at the article of Merikle and Skanes, they analyzed the relationship revolving around the actual effects of subliminal tapes on the way it enhances or helps users in their problems pertaining to various health reasons. â€Å"The present study was a direct attempt to evaluate possible placebo effects that may occur following regular listening to subliminal audiotapes† (Merikle and Skanes, 1992, p. 773) In their study though, the two did not mention any hypothesis concerning the relationship of subliminal tapes in achieving a placebo effect among its patrons. Due to this, after reading the article, a probable hypothesis that the researchers used in testing the study revolved around establishing the relationship and actual effect of subliminal tapes and the placebo effect among its users. In addition, the hypothesis may have been geared towards such claim due to the fact that in their analysis and discussion, the two pointed out that subliminal message/s in audiotapes have no relationship whatever to persons achieving a placebo effect and creating improvements in their certain problems. â€Å"The results of the present study provide no evidence whatsoever that subliminal audiotapes are an effective means for modifying behavior† (Merinkle and Skanes, 1992, p. 775) For what reason were researchers interested in testing this hypothesis; what do you think was their purpose in doing so? In the analysis of Merikle and Skanes, the researchers pointed out the importance of conducting this study. There had been various researches that emphasize the positive effects of subliminal tapes in achieving a placebo effect among patients. â€Å"Recent studies in which the efficacy of subliminal and placebo audiotapes has been compared are unanimous in showing no advantage for subliminal tapes relative to comparable placebo tapes† (Merinkle and Skanes, 1992, 772). In their own way of understanding, the authors used such contention to create a standpoint or view that subliminal tapes have no direct relationship in achieving placebo effect contrary to what other researches have been pointing out. Another reason of interest revolves around the notion that the author’s wanted to disprove the notion of many researches conducted by the producers of subliminal tapes towards the aim of achieving a placebo effect among patients. It is through this that they tried and tested their own analysis using data gathering and experimentation techniques. The authors in the study pointed out that there have been no striking differences in weight loss among the volunteer respondents. Seeing this, the purpose of Merinkle and Skankes is to create awareness among patrons to think again of purchasing these subliminal tapes. This is due to the results presented by the authors and several studies concerning the two concepts relationship. With this, the notion of the impact of subliminal tapes shall be lessened and its credibility is addressed and questioned appropriately. Briefly state the results After the respondents were tested using various research instruments, the study reported several findings that second the claim made by previous studies that indeed subliminal messages do not facilitate the creation of a placebo effect. Seeing the results, it revolved around the answers posted on postexperiment questionnaires, the loss of weight gained after using the subliminal device and the differences in the practices of their relative vices and problems. In postexperiment questionnaires, it showed a striking relation between the answers among respondents. It was said that â€Å"the answers that the subjects gave on the postexperiment questionnaires indicated that the three groups were roughly equivalent in terms of listening habits and life-style changes during the course of the study† (Merinkle and Skanes, 1992, 774). With regards to the issue surrounding weight loss and differences in practice, the results showcased little changes that can be characterized to be drastic in the analysis. It was mentioned that â€Å"a similar number of subjects in each group reported an increase in the number of times they participated in weekly exercises, and no more than 1 subject across all three groups reported a decrease in weekly exercise, a cessation in the use of tobacco, or a change in the use of oral contraceptives† (Merinkle and Skanes, 1992, 774). How could you apply the results of this study to helping students improve their marks in this (or any other) course? Applying this paper in the realm of student education, there are lessons that can be exhausted from their analysis. The first important facet that students must learn is to be critical about the information they gain. It is not sufficient for them to absorb information; they must synthesize these issues to create better understanding and personal development. In addition, by thinking critically about issues, students can gain advantage on how properly to address them – through research and testing. On the other hand, the results also point out that improvement must come from the individual. He/she does not need any instruments that will motivate him/her to pursue such actions. Only with the proper willpower can such issue be addressed appropriately and effectively. Can you think of any way this study could have been improved, or extended? A way this study can be extended is by allowing the time frame of the study to be longer than the usual. The objective of this is to actually determine in the long run if such subliminal tapes affect the creation of placebo effect. Also, better gauges, results and measurements can be established that can set a better outcome for the study. Reference Merikle, P. M. and Skanes, H. E.

Human Factors in Cockpit Design - Term Paper Example They get involved in behavioral/cognitive task-analysis, time analysis for assessment of various task demands, computer modeling for reach analysis and assessing the complexities of the task involved. It stems from the color selection to environmental considerations for the error free operations by pilot. It is essential that critical information is presented in the pilots field of view so that his potential energies are focused on the critical task. Information presented should be easy to interpret and presented in the way to avoid cluttering. The Head-Down-Display (HDD) and the Head-Up-Display (HUD) are the systems, which are capable of satisfying these needs. Advanced technological research tools like simulators are capable of giving a great insight in studying man-machine interaction to make travel safe and less burdensome for pilots. The journey is endless and it will continue to pose new challenges depending upon the complexities that will come on the way. Cockpit designing wil l also be impacted from the other technologies too and may culminate into totally a different shape and style not imagined by anybody so far. The purpose of any designers task while addressing Human Factor issue is to see the aspects of safety, ease of operation, and which is easy to learn. Good design promotes efficiency and consistency in task performance. That is the underlying principle on which cockpit designing is done. Cockpit is a compartment from where pilot controls the aircraft whether it is in air or on ground. The term is used to denote a place where pilot along with copilots are stationed with myriad of controls to navigate the aircraft. The cockpit contains various flight instruments and the controls to facilitate pilot navigation. The term is also sometimes used for the driver’s place in racing cars. Cockpit has a window which can be opened while the airplane is on the ground. Glass windows

Water Supply and Its Situation in Texas, Arizona, Oklahoma, Kansas, Ca Dissertation

Water Supply and Its Situation in Texas, Arizona, Oklahoma, Kansas, California, Nevada andMexico - Dissertation Example First, in the case of Texas that is experiencing about 40% of drought conditions as Hess & Frohlich write, the state needs to reverse the heavy use of water in the processing of natural gases in the fracking process (1). This will help save water and even save the agricultural sector. Oklahoma’s water problem may be solved by making agreements with other states on how it can save water even if it has to dig underground reservoirs for the same. Hess & Frohlich says that the same case would apply for Arizona since the state enjoys seasonal rains throughout the year (1). Through saving this water in underground reservoirs, the state can help deal with the severe drought conditions. Kansas, Nevada, and Mexico would greatly benefit from an institution of a water management plan that would even include the help of engineers to even construct underground pipes that will help store and transport water in the required places. For the case of California, investing in desalination water plants would prove useful since these plants as Hess & Frohlich explain would help save a lot of water that would have otherwise gone into waste (1). This water would also help in agricultural practices among the many farm workers in the state. From an analysis of the water supply conditions in these states, it is evident that there requires having stringent and timely measures to solve the water problems existing today. As seen in the compilation of Hess & Frohlich, fracking is a major contributor to drought in Texas (1). According to BBC, fracking is the process that involves drilling into the earth in the quest to release the gas underground (1). In this process, water of high pressure is directed at that underground rock so as to release the gas underneath. In the course of the fracking process, BBC writes that gas flares up from the ground either after the horizontal or a vertical process of hitting the rock layers.

Experiment on Size, Shape and Structures of Aggregates

Experiment on Size, Shape and Structures of Aggregates Introduction Dye sensitized solar cells (DSSC) have made considerable attention because of their unique features for conversion of free, unlimited solar energy into electricity by utilizing environmental friendly, inexpensive raw materials for low production cost1,2. DSSC composed of nanostructured, mesoporous semiconductors with wide-bandgap materials, to which the dye molecules (sensitizers) are adsorbed, a counter electrode and an electrolyte. In DSSC the dye molecule absorb visible light, and inject electron from photo-excited state of dye molecule to conduction band of semiconductor1,3 The performance of a dye-sensitized solar cell is mainly based on the structure of the visible light absorbing dye/ sensitizer. Applications of several natural carotenoid dyes with higher absorption coefficient in the visible region of the solar spectrum with higher conversion efficiency, is under investigations1,4. Carotenoids are C40 tertraterpenoid hydrocarbons consist of eight-C5 isoprene units5. The major characteristic feature of Car molecule is it comprises of extensive conjugated system of delocalized Ï€-electrons which makes them highly hydrophobic molecules. Therefore when these carotenoid molecules are dissolved in hydrated solvents they tend to form aggregates since the molecule is hydrophobic in nature. The surface arrangements and the aggregation behavior of the sensitizers (carotenoids) on semiconductor nanoparticles is greatly influenced the performance of carotenoid based artificial photosystems such as DSSC. It was stated (Wang et al.2006) that formation of dye aggregates suppresses the performance of DSSC6 since the device performance is influencing the nanoscale morphology of the aggregates. Therefore several researchers have focussed on the nanoscale organization of molecular aggregation in solutions of these conjugated molecules at atomic level resolution. Interchain agg regation behavior of a conjugated polymer (DP10-PPV) which used in opto-electronic applications such as pohotovoltaics, dissolved in two solvents having different qualities at different concentrations were studied by (Chen et al. 2009) using Small angle neutron scattering (SANS), revealed that the internal conformational structure of these network aggregates were differ in different solvents. A similar study was also carried out by Chen and coworkers for another semirigid conjugated polymer (DP6-PPV) in solutions7,8. Moreover it has been reported that, when carotenoid molecules are deposited on the surface of semiconductor often it forms H-shape aggregates5. Aggregation phenomena of natural and artificially modified carotenoids were proved that J- and H-aggregates are the possible geometries9. Apart from the formation of self-assembled aggregates in hydrated solvents of these carotenoid molecules, there is strong relationship between the structural conformation and the composition o f molecules in the solution with the ability of aggregation5. Polar carotenoids consist of –OH (hydroxyl groups) in the carotenoid structure promotes the formation of aggregates compared to the molecules without any functional groups, (Simonyi et al. 2003). Furthermore the position of the functional group may also significantly affect the type of aggregates form10. It was observed experimentally for the first time (Cheng et al. 2009), the crossover from swollen coils in semidilute regime to unperturbed coil at high concentrations11 with the variation of polymer radius of Gyration (Rg) of poly(methyl methacrylate) in chloroform as a function of polymer concentration (à Ã¢â‚¬ ¢). Perahia et al. used SANS data12to investigate how molecular solutions of poly(2,5-dinonylparaphenylene ethynylene)s (PPE) aggregates into large flat clusters. Ratnaweera et al. 2012 and Lodge and coworkers were studied self-assembly modes of several block copolymers in selective solvents using SANS13 -15. Therefore the studies of dye aggregates are really essential for future developments of carotenoid based electrochemical devices for solar energy conversion. Spectroscopic studies on carotenoids in hydrated solvents revealed that the aggregation behavior of carotenoids is significantly affecting the S0 →S2 electronic transition16 of neutral carotenoids. Therefore the solvent quality is one of the major factors for carotenoid solutions which govern the size of the aggregate. When the carotenoid molecules are uniformly dissolved in a good solvent at low concentrations to form a homogeneous mixture, carotenoids are exist as isolated molecules that are very far from each other17. Therefore the interactions between monomers are very weaker than the monomer-solvent interactions and polymer tends to swells and its size is larger than the ideal size13,18. Cheng coworkers stated11 that in the good solvent domain (T > ÃŽ ¸), the repulsions of excluded volume is greater which results Rg of the aggregates enhanced beyond its unperturbed size. Further this expansion effect is greater in dilute solutions since the volume fraction of polymer is very low compared to its overlapping concentration. When the concentration of the solution is increased, the attraction between monomers are stronger and the aggregates tried to collapses into globules wit h solvents inside it corresponds to a poor solvent. The size of the structural conformation of collapsed globule is smaller than the ideal chain17. For a polymer solution (NA = N and NB = 1) to be favorable for mixing or aggregation is depends on the Flory-Huggins equation which consist of two terms, the entropy and energy terms17. The energy change of binary mixing which depends on composition of the mixture is the main factor, for a polymer to be dissolved in a good solvent to make an equilibrium state of a homogeneous mixture of polymer solution. Entropy of mixing is small for polymer solutions and always positive hence promotes mixing, but the energy of mixing is either positive or negative which measures the attractive or repulsive interactions between species. The net attraction between species in the solution is important because it measure the value and the sign of the Flory interaction parameter (χ) and hence to know whether the given mixture consist of single-phase or separated into phases. In this research the small angle neutron scattering (SANS) data was used to investigate the quantitative experimental information on size, shape and structures of aggregates. Two carotenoid molecules, bixin and norbixin were selected in this study to characterize their structural information of monomeric and aggregated forms. The natural dyes, bixin and norbixin are belongs to the group of apo-carotenoids, extracted from annatto seeds of the Bixa orellana tree1. The chemical structures of cis-bixin (C25H30O4) and cis-norbixin (C24H28O4) is shown in fig. 1. (1) Gà ³mez-Ortà ­z, N. M.; Và ¡zquez-Maldonado, I. A.; Pà ©rez-Espadas, A. R.; Mena-Rejà ³n, G.

Comparing the Use of Setting in The Shawl and The Portable Phonograph E

Use of Setting in "The Shawl" and "The Portable Phonograph"  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚   In literature, setting is often used to enhance or develop characters, provide realism, and create a mood or atmosphere for a story (Roberts 256). Two short stories, "The Shawl" by Cynthia Ozick and Walter Van Tillburg Clark’s "The Portable Phonograph" explore victims of war in the vivid settings that the authors have created. Although both works are vague as to geographic setting and place in time, the authors’ detailed descriptions of the character’s surroundings envelop the reader and lend an air of authenticity to the tales (Kauvar 180). "The Shawl" and "The Portable Phonograph" differ in their treatment of symbolism and characterization but their ingenious use of setting to create a theme unites these two stories. "The Shawl" and "The Portable Phonograph" both open with intense, haunting descriptions; Ozick shocks readers with her portrayal of "the Holocaust in searingly vivid sensory impressions" (Watson 892) and Clark dedicates his first three paragraphs to describing a desolate, war torn plain devoid of almost all life. Clark immediately creates a sense of a dangerous, foreboding world, describing a "sensation of torment" that "arose from the stillness of the earth air beneath the violence of the upper air" (Roberts 260). The reader is left with an impression, filled with detail, but moreover, overflowing with emotion. "The Shawl" and "The Portable Phonograph" contain objects that are critical to the stories and to the mental states of the characters contained within. In the former story, the Rosa believes the shawl protects her baby from the horrors of the Holocaust, the scrap of cloth provides her with hope that the next generation wi... ...rough their thoughts. The settings in these two stories act as more than simply a backdrop for a tale, they are used "to create meaning, just as painters include backgrounds and objects to render ideas" (Roberts 255).    Works Cited Kauvar, Elaine M.
