Sigmund Freuds Theory of Psychoanalysis Essay example

Sigmund Freuds Theory of Psychoanalysis Freuds methods of psychoanalysis were based on his theory that people have repressed, hidden feelings. The psychoanalysts goal is to make the patient aware of these subconscious feelings. Childhood conflicts that are hidden away by the patient, become revealed to both the analyst and the patient, allowing the patient to live a less anxious, more healthy life. Methods of hypnosis were originally used by Freud to find the cause for anxiety, but he dismissed them as being too inaccurate. He started to use methods of free association to delve into the patients sub-conscious. By assessing the patients reactions to the analysts suggestions, Freud saw that the analyst could help the†¦show more content†¦Through the slips made when the patient was told to carry out the free-association process, and some of the patients beliefs and habits, Freud could delve into the patients subconscious. These thoughts produced a chain directly into the patients subconscious, and unearthed memories and feelings. This process soon became known as psychoanalysis. Freud also believed that dreams were an important way of getting into the patients subconscious. By analyzing dreams, he could reveal the basis of conflict within the patient. Freud believed the mind was made up of three main parts: the conscious, the preconscious, and the subconscious. The conscious region is the part that people are most aware of and what others can see. The preconscious region holds thoughts and feelings that a person can become aware of but that are mostly hidden away. Finally, the subconscious region consists of thoughts and feelings which are completely hidden away and which one is mostly unaware of. Some believe that the preconscious region is really a small part of the much larger subconscious region. Freud said that the mind is like an iceberg, with most of it, the subconscious, hidden away, and only a small part, the conscious, showing above the water, able to be seen. Why, then, would the majority of the mind be hidden; why is the subconscious region so much larger than the conscious region? Freud explained that the answer is that oneShow MoreRelatedSigmund Freuds Theory Of Psychoanalysis1636 Words   |  7 Pages This passage from â€Å"Psycho-analysis,† Sigmund Freud’s essay detailing the origins, methods, and applications of his theory of psychoanalysis, reveals the utility of his approach in understanding what lies beneath the surface through the interpretation of dreams, which later psychoanalytic critics related to the interpretation of literature.

Life Of Standout Basketball Player Michael Brooks Essay

Family, friends, and former teammates gathered at Founders’ Hall School of Business on the campus of La Salle University on Saturday to remember and celebrate the life of standout basketball player Michael Brooks. Brooks, 58, passed away on August 22, 2016 and had a storied basketball career. His basketball playing days began at West Catholic High School and continued in the Sonny Hill League as he played with guys such as Gene Banks and Louis Lloyd. Brooks then went on to play all four years at La Salle, was named to the 1980 United States Olympic men’s basketball team and played professionally in the NBA and overseas. Over his four-year career at La Salle, Brooks put up outstanding numbers as he amassed 2,628 points and 1,372 rebounds. In his senior year, Brooks averaged 24.1 points and 11.5 rebounds per game and was named the NCAA Kodak National Player of the Year.

Human Resources And Sustainable Development - 1378 Words

Humanity has the power to make development sustainable. This power ensures that development will meet the needs of the present without disrupting the ability of future generations to pursue their own particular desires. Sustainable development is maintaining harmony between the human need to improve lifestyles and preserving natural resources and ecosystems, for which present and future generations depend on. Too often, in today’s world, development is driven by one specific need, without completely considering the boundless future effects. Humanity has already observed the damage and felt the harm this type of approach can cause, from final crisis and irresponsible banking, to dramatic changes in atmospheric temperatures resulting from our dependence on fossil fuel-based energy sources. The longer we pursue unstainable development, the more frequent and extreme its consequences are likely to become, which is why it is curtail to take action immediately.

Almost 46,000 merchants across the U.S accepted WIC vouchers that provide nutritious foods for families in 2015, according to the USDA. WIC has established overall goals of providing â€Å"vouchers for supplemental nutritious foods, education and counseling at WIC clinics, and screenings/referrals to other health and welfare services† (USDA, 2015). In addition to these goals, WIC has joined the Healthy People 2020 federal initiative to achieve the major breastfeeding goals of†¦show more content†¦It should be noted that these services vary according to population needs, with some studies even indicating that services vary based on the racial background of the participants (Evans, Labbok, Abrahams 2011). This should be a cause for concern, and discrepancies in services provided must be avoided to limit further disparities. Data from the Centers for Disease Control (2016) found that in 2010, the rates for breastfeeding initiation was 74% for Native American women, which was lower than other groups. In order to better combat breastfeeding disparities, the WIC program continues to tailor their breastfeeding support services to achieve the Healthy People 2020 goals by increasing the number of trained staff, holding community involvement sessions, and constructing additional educational components. WIC partners with Indian Tribal Organizations (ITOs) to provide nutritional services to approximately 63,000 Native American participants. Similar to the general population of the U.S., almost half of Native American women are enrolled in the WIC program (USDA, 2015; Evans, Labbok, Abrahams, 2011).

Applying the Full-Range Leadership Model free essay sample

As the new wing safety officer, I have been asked to eradicate the trends in safety mishaps and make sure there is a process in place to prevent future occurrences. This paper will outline an analysis of the current leadership, the application of the Full-Range Leadership Model (FRLM) concepts in my solution, a plan of action, and set goals to track progress. The Analysis Based on the interviews conducted with the previous safety officer and the team members, I noticed that each member has various strengths that can be utilized in a new campaign to combat the safety issues. Understanding these strengths has helped me to identify their leadership styles under my predecessors reign. Col Parker exhibited a passive management by exception approach with my predecessor, Capt Matthews. As a transactional leader, Col Parker assigned the task to Capt Matthews, monitored his performance, and then stepped in when things were going awry. We will write a custom essay sample on Applying the Full-Range Leadership Model or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Capt Matthews failed to make an impact on reversing the safety mishaps trend. This was primarily due to him exhibiting a laissez-faire approach when it came to exploiting the talents of his team to accomplish the mission. His past experiences gave him the tools to ascertain success, but not developing SSgt Williamsons willingness to engage others, and her proactive community involvement or apitalizing on MSgt Jones and Mr. DeBurghs seasoned experience and wealth of knowledge specific to the base was his downfall. Moreover, Lt Johnson was allowed to be a non-engaged member of the team. He was not given a leadership role or an opportunity to employ his skills in management and marketing leaving him unmotivated. The Application Leadership comes from top down and in this case Col Parker needs to enhance her transactional leadership tools from Management by Exception to Contingent Reward or CR (discussed later in the plan of action) and strengthen her transformational leadership. She exhibits individual consideration by treating the members within the wing as family, not Just subordinates. She has the people behind her simply because they know she genuinely cares about them and their well-being. This can be capitalized on as part of a new campaign to put an end to the mishaps. MSgt Jones and Mr. DeBurgh have a plethora of experience between the two of them that can be harnessed and developed. I will provide the intellectual stimulation (IS) for these team members to get them back in the game to provide ideas for a new safety conquered based on prior experiences and MSgt Jones can possibly provide cutting dge technologies in mishap prevention from the classes he takes. SSgt Williamson is ready and willing to work wherever she is needed. Shes been placed in an administrative role, but her passion regarding the recent mishaps surpasses her knowledge of file plans.

ABOUT THE INTERACTION BETWEEN MOLECULES Essay Example For Students

ABOUT THE INTERACTION BETWEEN MOLECULES Essay The properties observed for matter on the macroscopic level are determined by the properties of the constituent molecules and the interactions between them. The polar or non-polar character of a molecule will clearly be important in determining the nature of its interactions with other molecules. There will be relatively strong forces of attraction acting between molecules with large dipole moments. To a first approximation, the energy of interaction between dipolar molecules can be considered as completely electrostatic in origin, the negative end of one molecule attracting the positive end of another. The presence of intermolecular forces accounts for the existence of solids and liquids. A molecule in a condensed phase is in a region of low potential energy, a potential well, as a result of the attractive forces which the neighbouring molecules exert on it. By supplying energy in the form of heat, a molecule in a solid or liquid phase can acquire sufficient kinetic energy to overcome the potential energy of attraction and escape into the vapour phase. The vapour pressure (the pressure of the vapour in equilibrium with a solid or liquid at a given temperature) provides a measure of the tendency of a molecule in a condensed phase to escape into the vapour; the larger the vapour pressure, the greater the escaping tendency. The average kinetic energy of the molecule in the vapour is directly proportional to the absolute temperature. Thus the observation of a large vapour pressure at a low temperature implies that relatively little kinetic energy is required to overcome the potential i nteractions between the molecules in the condensed phase. We will write a custom essay on ABOUT THE INTERACTION BETWEEN MOLECULES specifically for you for only $16.38 $13.9/page Order now The only potential interactions possible between non-polar, covalently bonded molecules are of the van der Waals type as previously discussed for the interaction between two helium atoms at large internuclear separations. Molecules such as H2 and N2 have closed shell electronic structures in the same sense that helium does; all of the valence electrons are paired and no further chemical bonding may occur. The small polarizations of the charge densities induced by the long-range interactions of closed shell atoms or molecules result in only weak forces of attraction. The low boiling points (the temperature at which the vapour pressure above the liquid phase equals one atmosphere) observed for substances composed of molecules which can interact only through a van der Waals type force are, therefore, understandable. Table 7-6 lists the normal boiling points for a number of representative compounds. Table 7-6. Normal Boiling Points (K)Substance BP SubstanceBP SubstanceBP He 4.2 NH3240 NaCl 1686H2 20.4HF 292 LiF1949N2 77.4H2O373 BeO 4100Ar87.4 An argon atom is larger than a helium atom and its outer charge density is not bound as tightly as that in helium. (Recall that the ionization potential for argon is less than that for helium.) Consequently, the charge density of argon is more polarizable than that of helium and the forces of attraction between argon atoms and hence its normal boiling point are correspondingly greater. These same forces do, of course, operate in the gas phase as well and are the cause of the observed deviations from ideal gas behaviour. The interactions between polar molecules such as HF and H2O will be much larger and their normal boiling points greater than those observed for the non-polar molecules. When hydrogen is present at the positive end of a polar bond, the dipolar interactions are particularly strong and are given a special name, hydrogen-bonded interactions. The hydrogen bond increases in strength as the electronegativity of the atom to which the H is chemically bonded increases. (We noted previously that the dipole moment in the HA molecules increased as A was made more electronegative.) Liquid hydrogen fluoride consists of chains of molecules joined end to end; each hydrogen of one molecule is attracted to the fluorine of the next. In liquid water, each water molecule is hydrogen bonded to four other water molecules. This accounts for what appears to be an anomalously high boiling point for water when compared with the values observed for the neighbouring hydride molecules NH3 and HF. .u9383b09ecd9d688a77f365b4d3ab690f , .u9383b09ecd9d688a77f365b4d3ab690f .postImageUrl , .u9383b09ecd9d688a77f365b4d3ab690f .centered-text-area { min-height: 80px; position: relative; } .u9383b09ecd9d688a77f365b4d3ab690f , .u9383b09ecd9d688a77f365b4d3ab690f:hover , .u9383b09ecd9d688a77f365b4d3ab690f:visited , .u9383b09ecd9d688a77f365b4d3ab690f:active { border:0!important; } .u9383b09ecd9d688a77f365b4d3ab690f .clearfix:after { content: ""; display: table; clear: both; } .u9383b09ecd9d688a77f365b4d3ab690f { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u9383b09ecd9d688a77f365b4d3ab690f:active , .u9383b09ecd9d688a77f365b4d3ab690f:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u9383b09ecd9d688a77f365b4d3ab690f .centered-text-area { width: 100%; position: relative ; } .u9383b09ecd9d688a77f365b4d3ab690f .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u9383b09ecd9d688a77f365b4d3ab690f .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u9383b09ecd9d688a77f365b4d3ab690f .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u9383b09ecd9d688a77f365b4d3ab690f:hover .ctaButton { background-color: #34495E!important; } .u9383b09ecd9d688a77f365b4d3ab690f .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u9383b09ecd9d688a77f365b4d3ab690f .u9383b09ecd9d688a77f365b4d3ab690f-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u9383b09ecd9d688a77f365b4d3ab690f:after { content: ""; display: block; clear: both; } READ: Educational research single su Essay The condensed phases so far considered are called molecular solids or molecular liquids because the identity of the individual molecule is largely retained. As the forces between the molecules become larger, the point of view of regarding a solid as a collection of individual, interacting molecules becomes less satisfactory. In the limiting case of the strong interactions which exist between the ions in an ionic crystal, the concept of a discrete molecule in the solid phase ceases to exist. In solid KCl, for example, the potassium and chloride ions exist as separate entities; each potassium ion is in contact with six chloride ions, whic h in turn are each in contact with six potassium ions. Each ion attracts its six neighbouring ions equally and thus the structure is symmetrical and therefore cubic; six ions of one sign occupy the centres of the faces of a regular cube with an ion of opposite sign at its centre. The number of nearest neighbours a given ion has in an ionic crystal is determined by the relative sizes of the positive and negative species. The Be+2 ion is considerably smaller than O-2 and the basic structure of BeO is tetrahedral, each ion surrounded by four ions of opposite charge. The strong electrostatic forces between the ions in a crystal are reflected in the high boiling points recorded in Table 7-6 for the ionic compounds.
