What You Need to Know About Weekend MBA Programs

What You Need to Know About Weekend MBA Programs A weekend MBA program is a part-time business degree program with class sessions that are held on the weekend, usually on Saturdays. The program results in a Master of Business Administration degree. Weekend MBA programs are typically campus-based but may incorporate some form of distance learning, such as video-based lectures or online discussion groups. Most weekend MBA programs are just that: programs that take place on the weekend. However, there are some programs that have weekend and evening classes. Programs like this have classes on the weekend as well as classes that take place in the evening on weekdays. Types of Weekend MBA Programs There are two basic types of weekend MBA programs: the first is a traditional MBA program for students who would enroll in a typical MBA degree program, and the second is an executive MBA program. An executive MBA program, or EMBA, is specifically designed for corporate executives, managers, and other working professionals with extensive work experience. Although work experience can vary, most executive MBA students have 10-15 years of work experience on average. Many executive MBA students also receive full or partial company sponsorship, meaning that they typically receive some form of tuition reimbursement. Top Business Schools With Weekend MBA Programs There are a growing number of business schools offering weekend MBA programs. Some of the top business schools in the country offer this program option for people who want to attend school part-time. Some examples include: The University of Chicago Booth School of Business: At Chicago Booth, students meet every Saturday for 11 weeks at a time and earn an MBA degree in 2.5 to 3 years. The curriculum for the weekend MBA program is the same as the curriculum for the full-time MBA program.The University of California Berkeley Haas School of Business: At Berkeley Haas, students can choose from a weekend or evening schedule for MBA classes and could earn their degree in as little as 2.5 years. Weekend MBA classes are held on Saturdays in the spring and fall, but year-round activities are available.Kellogg School of Management at Northwest University: Kelloggs weekend MBA program takes place on Saturdays, but students can choose to take evening classes in addition to weekend classes. There are two weekend MBA options: traditional pace and accelerated. The traditional option takes 20.5 months to complete, while the accelerated option requires fewer credits and evening classes and takes 15.5 months to complete. Pros and Cons of Weekend MBA Programs There are many good reasons to consider a weekend MBA program, but this education option might not be the best choice for everyone. Lets explore a few pros and cons of weekend MBA programs. Pros The biggest advantage of weekend MBA programs is that you can take all of your classes on the weekend, which makes it easier to work part-time or full-time while you earn your degree.A weekend MBA program may make it easier to attend a business school that is not located near your home. It is not unusual for MBA students to fly in from somewhere else for weekend classes.Some full-time MBA programs take two years to complete. You can often earn your degree in the same amount of time (or close to it) as you would in a full-time program by attending part-time weekend MBA programs.Some weekend MBA programs allow you to reduce your tuition costs. In other words, you might pay less for a weekend MBA program than you would for a traditional, full-time MBA program. Cons Classes might take place just one day per week in a weekend MBA program, but you will have to put in work on other days of the week to keep up with your studies.Being able to put what you learn into practice right away in an advantage for students who work while they attend school, but it is also important to remember that it can be exhausting to work and study at the same time. Furthermore, there will come a day when you have to choose between work and academic commitments, and one is likely to suffer because of your choice.Students in full-time programs sometimes get the opportunity to spend more time with their cohorts, which is conducive to relationship building. In a weekend MBA program, you may not have as many opportunities to network or make friends.

Quantum Number Definition (Chemistry and Physics)

Quantum Number Definition (Chemistry and Physics) A  quantum number is a value that is used when describing the energy levels available to atoms and molecules. An electron in an atom or ion has four quantum numbers to describe its state and yield solutions to the Schrà ¶dinger wave equation for the hydrogen atom. There are four quantum numbers: n - principal quantum number - describes the energy levelâ„“ - azimuthal or angular momentum quantum number - describes the subshellmâ„“Â  or m - magnetic quantum number - describes the orbital of the subshellms or s - spin quantum number - describes the spin Quantum Number Values According to the Pauli exclusion principle, no two electrons in an atom can have the same set of quantum numbers. Each quantum number is represented by either a half-integer or integer value. The principal quantum number is an integer that is the number of the electrons shell. The value is 1 or higher (never 0 or negative).The angular momentum quantum number is an integer that is the value of the electrons orbital (e.g., s0, p1).  Ã¢â€žâ€œ is greater than or equal to zero and less than or equal to n-1.The magnetic quantum number is the orientation of the orbital with integer values ranging from -â„“ to  Ã¢â€žâ€œ. So, for the p orbital, where  Ã¢â€žâ€œ1, m could have values of -1, 0, 1.The spin quantum number is a half-integer value that is either -1/2 (called spin down) or 1/2 (called spin up). Quantum Number Example For the outer valence electrons of a carbon atom, the electrons are found in the 2p orbital. The four quantum numbers used to describe the electrons are n2,  Ã¢â€žâ€œ1, m1, 0, or -1, and s1/2 (the electrons have parallel spins). Not Just for Electrons While quantum numbers are commonly used to describe electrons, they may be used to describe the nucleons (protons and neutrons) of an atom or elementary particles.

The impact of Information Technology on a career or profession of your Term Paper

The impact of Information Technology on a career or profession of your choice - Term Paper Example Industry leaders keep talking about ways to gain competitive edge and their action plan in this context invariably highlights the strategic value that Information Technology now holds for the industry. Information Technology has had very strong social, economic and professional impacts to an extent that it transformed everyone’s life from a student up to almost all the Heads of State. Healthcare – a socially relevant domain too has been impacted by the applications of Information Technology. In almost all the countries, the healthcare delivery system is facing unbending and intransigent issues. The key issue that the healthcare deliver systems worldwide face is: Uneven distribution and shortage of infrastructural and human resources at primary, secondary, tertiary and even super-speciality levels within a healthcare delivery system. This issue gives birth to disparity within the boundaries/same region. This disparity, at times, produces strange dynamics those have the p otential to create serious imbalances which are unique to each setting. The issues being faced by healthcare delivery systems are such that they not only highlight existing gaps but can also affect the utilisation of the resources available; such unyielding issues need extraordinary solutions. Information Technology through its highly promising applications is helping this one of the most significant parameter of human development to scale newer challenges (being raised because of ever increasing demands at the healthcare delivery systems, expectations of the beneficiaries), in order to improve efficiency of clinicians and enhance quality of life of the populace on the planet. It is worth mentioning that there are numerous applications of Information Technology and each of them is aimed at empowering all or at least one of the following stakeholders: healthcare delivery systems, clinicians and the patients alike. This research throws light on some of the cutting edge applications of Information Technology in this safety and security domain of medicine and it also includes the impact that these applications have made on the clinicians and paramedical personnel. Telemedicine (Sood, et al., 2007) is a flagship application of Information Technology in health that uses communications networks for delivery of healthcare services and medical education from one geographical location to another. Ranging from public health to surgery, telemedicine has found its roots in almost all the specialities of medicine and this is the reason that gradually telemedicine is merging with the delivery of mainstream healthcare services. Telesurgery and mHealth are two upcoming forms of telemedicine but they have already proved to be practically feasible, reliable, useful and safe. Both these forms of telemedicine can be practised in the modes of teleconsultation (between a doctor and a patient or between a general physician

Describe how to extract evidence in relation to HTTp,FTP and SMTP Research Paper

Describe how to extract evidence in relation to HTTp,FTP and SMTP application layer protocol - Research Paper Example In this paper, I present the techniques used to extract data sent from one host to another over a TCP-based network like the internet using FTP protocol, an e-mail sent over an IP network using SMTP protocol and the one sent over web-based applications using HTTP protocol. Contents Contents 3 1.0Introduction 1 2.0Extracting evidence in relation to HTTP 1 Extraction of Posting Behavior from HTTP Header 1 3.0Extracting evidence in relation to SMTP 2 Header analysis 3 Bait tactics 3 Server investigation 3 Network device investigation 3 Software embedded identifiers 3 Sender Mailer Finger prints 3 4.0Extracting evidence in relation to FTP 3 5.0Conclusion 4 6.0 References 1 1.0 Introduction The network has become the beast way of transferring information to support both personal and business requirements. However, as different services have been enabled across the network environment, the potential for cyber-crime has grown with these. Unfortunately, not only are criminals exploiting this medium to an unprecedented degree but we are now looking at the potential of cyber-warfare or cyber-terrorism who are communicating through these protocols hence need for methods of extracting data from these protocols as a source of evidence. [24] File transfer protocol (FTP) is a network protocol that is used to transfer files from a host server to a client over a TCP-based network such as the internet. It is based on client-server architecture and it uses separate data and control connections between the client and server. [5] Simple Mail Transfer Protocol (SMTP) refers to a protocol that transmission of an e-mail across and IP- based network. However clients in the network use SMTP only for sending messages to a mail sever while for receiving they use POP (Post office protocol) or IMAP (Internet Message Access Protocol). This enables them to access their mail box accounts on a mail sever. HTTP (Hypertext Transfer Protocol) is an application protocol used by distributed and coll aborative hypermedia information systems. [19] The HTTP protocol is the basis of World Wide Web (WWW). All Web-based applications rely on this protocol for security and transactions ranging from home banking, e-commerce and e-procurement and to those that deal with sensitive data such as career and identity information. This protocol can also be used to prevent unauthorized viewing of personal, financial, and confidential information over the Web. [20] 2.0 Extracting evidence in relation to HTTP In relation to the amount of content in the web, users need help in finding information of interest, and service providers are required to provide such information. This can be done by estimating the user’s profile i.e. analyzing the behavior of the user when she is online by using access logs in a server. In order to recognize the actual user behavior across many servers, the behavior is analyzed using the flow of data on proxy servers. Some users post their messages on the Web while others just browse web pages and hence an approach has to be made in order to extract both the users’ behaviors. [6] When a user is just browsing web pages, the browser usually sends HHTP GET requests in which the request parameters are described in the URL (e.g., http://search.goo.ne.jp/web.jsp?MT=ntt means that the value of parameter MT is ntt). When the user posts a message, requests and responses are sent by HTTP POST, instead of HTTP GET.

Great Traditions In Ethics Essay Example for Free

Great Traditions In Ethics Essay The overcoming of the fear of death figures as a key component of Epicurean philosophy. Because the Epicureans valued above all other accomplishments, the living of a good life and that pleasure is the end of all morality and that real pleasure is attained through a life of prudence, honor, and justice the acknowledgment in Epicurean philosophy that the fear of death intrudes upon individual happiness is not at all the same as admission that fear of death is an insurmountable condition, (Epicureanism). To the contrary, the epicurean philosophy seeks forts to identify the root causes of the fear of death, which are: 1) The fear of being dead. 2) The fear that one will die, that ones life is going to end. 3) The fear of premature death. 4) The fear of the process of dying and for each of these considerations, Epicurean philosophy provides a response. The intention of epicurean philosophy is to persuade its adherents that death is not bad for the person who dies although death is inevitable and is the total annihilation of that person; despite the belief in total annihilation Epicurus held no regard for death itself. The basic center of the Epicurean refusal to fear death lies in the epicurean belief that God should not concern to us. Death is not to be feared and these facts are unchangeable despite ones subjective, emotional reactions. because death means the end of consciousness and the total annihilation of the individual, nothing exists beyond death which may cause fear at all,(Warren 4-7). It is only by admitting the fear of death and addressing it straight on through applied logic rather than religion or mysticism that the fear of death can be conquered. The Epicureans regarded the overcoming of the fear of death at the very heart of their ethical project. They identified the goal of a good life as the removal of mental and physical pain. Mental pain they further characterized as anxieties and fears because fear of death causes pain to the individual it must be overcome and it can be overcome by logical acceptance of the fact that death holds no pain for the person who experiences it. (Warren 6) Just as the fear of death prevented many individuals from achieving happiness in life, justice (or lack thereof) provides enmity to happiness in the Epicurean ethical tradition. For Epicurus, laws and justice are a matter of personal bearing and dignity as well as intelligence and experience. Under an Epicurean ethic, in a world full of Epicurean sages there would be no need for written prescriptive laws. Everyone in that case would be able to see and remember what contributes to the utility of the community and would act accordingly (Warren 183). The idea of breaking a rule of justice is wrong because it causes the eventual pain or threat of pain or disturbance to oters happiness as well as ones own. Unlike Epicurus, St. Augustine sees the need for rigid law to control human society and he envisions this law emanating directly fro the Divine. In his distinction between the City of God and the City of Men he makes clear that the church is divinely established and leads humankind to eternal goodness, which is God and that in the ideal city, The state adheres to the virtues of politics and of the mind, formulating a political community. Both of these societies are visible and seek to do good. (Bonner 54) By contrast, the City of Man exists to serve selfishly driven needs and does not partake of the Divine spirit of creation and Divine Law. The idea of self-love against the love of God separates the two cities an idea which springs from what Augustine was afterwards to regard in The City of God as the architect of the Earthly Citylove of self to the contempt of God (Bonner 54).

Political Change in Europe in the Modern Era Essay examples -- World E

European nations gained world dominance between the 15th and 19th centuries through imperialism and industrialization. European nations competed among themselves for international influence, and established by the early 20th century a very intricate balance of power, the disturbance of which ignited World War I in 1914. Over this same period, the power of monarchs within European nations declined as a larger portion of the populace demanded political rights, leading to the democratization of most political systems throughout Western Europe. These shifts in political systems were fed by urbanization, by the rise of class consciousness within the masses, and by the spread of ideas of political and economic philosophers who challenged the power of autocratic government. Russia from Tsarism to Bolshevik Dictatorship Russia lagged behind Western Europe in its economic and political development. In the mid-19th century, Russia remained a feudal society with very little industrialization or urbanization, whose tsar had absolute power. Serfs, peasants who were bound to landowners and had no political rights, comprised the vast majority of the population. Tsar Alexander II (1855-1881) initiated an Age of Reform that he hoped would modernize Russia while maintaining the absolute power of the tsar. In 1861 Alexander II emancipated the serfs, on the grounds that â€Å"it is better to abolish serfdom from above than to wait until the serfs begin to liberate themselves from below.† This act put into place a complicated system by which the peasants acquired a â€Å"temporary obligation† to the landlord that could drag on for years, and had to pay to purchase land that they had considered their own and that was often much smaller than the am... ... of the tsar in the late 19th century until the establishment of the Bolshevik dictatorship in October 1917. The moderate pro-monarchist factions (â€Å"whites†) and the Bolsheviks (â€Å"reds,† renamed the Russian Communist Party in 1918) engaged in a Civil War until 1922, by which time the RCP had defeated the monarchists and reclaimed the border nations that had been part of the Tsar’s empire, with the exception of Poland, Finland, and the Balkan states. With these victories the RCP established the Union of Soviet Socialist Republics (USSR), which became a powerful contender in world affairs under Stalin’s rule (1924-1953). The ideological and practical disconnect between Russian Communism and Western Democracy and the alliances of World War II were the foundations of the Cold War rivalry between the world’s two superpowers in the 20th century, the USSR and the USA.

PH Lab Experiment Essays - Equilibrium Chemistry, Titration, PH

PH Lab Experiment Essays - Equilibrium Chemistry, Titration, PH pH Lab Experiment By Jeff Price Biology 101- 011 Dr. Art Ellis 1 May 1997 Trident Technical College Charleston, South Carolina 29423 pH Lab Experiment Abstract: Upon hypothesizing that stomach medicines are useful in neutralizing the acidic affects of beverages when used properly an experiment was designed to test this theory. The experiment incorporated the use of white grape juice to be the acid, Maalox as the antacid, and red cabbage juice as the pH indicator. A control group was also formulated by substituting distilled water for the antacids. After mixing the solutions in separate test tubes, any changes were recorded. These changes were the indicators for the pH level of the mixture. The tube containing white grape juice changed to a pink color (pH value 3). The tube containing Maalox changed to a greenish blue (pH value of 8). There was no change in the control group. Then when white grape juice and Maalox were tested, a blue color resulted (pH value of 7, neutral). Therefore, the experiment shows that antacids can be effective neutralizers with proper use and understanding of how they work. Introduction: pH is the measurement of positive hydrogen ions (H+) in solution. A substance that has a high concentration of H+ is acidic. A substance that has a low concentration of H+ is basic (alkaline) (Dickey, 1995). The measurements of pH are obtained through paper tests, machine measurements, or the use of other indicators. Most of these other indicators rely on a change in a mixtures color in order to determine the pH level of the substance. These colors have been coordinated with pH values. The pH values begin at 0 and run to 14. A pH value of 0-6 indicates an acidic solution. A pH value of 7 indicates a neutral substance and a pH value of 8-14 represents a base (Starr and Taggart, 1995). The ability to measure pH has become important in the manufacture of foods, paper, and chemicals (Altwicker and Micheal, 1985). In the following experiment, a pH comparison is made between beverages and stomach medicines. Some studies suggest that antacids may be of no benefit or may actually be harmful to the user (Graf, 1985). One hypothesizes is that stomach medicines are useful in neutralizing the acidic affects of beverages when used properly. Materials and Methods: The experiment was conducted using eight clean test tubes, parafilm, red cabbage juice, white grape juice, 7UP, Club Soda, Seltzer Water, Milk of Magnesia, Sodium Bicarbonate, and Maalox With a 5mL delivery pipet and a green pi-pump, 3mL of either a beverage or medicine was added to the test tubes. In the eighth test tube, 3 milliliters of white grape juice and Maalox were combined. The tubes were labeled accordingly and then placed in a holding rack. Using a clean 5mL pipet with pi-pump, 3mL of red cabbage juice was added to each of the eight solutions. Parafilm was used to cover the test tubes and then the mixture were lightly shaken. Results: The reaction (color) of each test tube solution of either beverage or stomach medicine was compared to the color spectrum. The pH values of each solution was then recorded. The following chart shows the pH value of each solution. BeveragepHMedicinepH White grape Juice3Milk of Magnesia12 7UP4Sodium Bicarbonate10 Club Soda6Maalox8 Seltzer Water5 CombinationSolution White grape juice/Maalox 7 The beverages used in this experiment fully represent the acidic end of the pH scale (6-0). Stomach medicines in this case, represent the base side of the scale (8-14). On the pH scale, 7 is neutral and thus white grape juice mixed with Maalox resulted in a pH of 7. Discussion and Conclusion: In this pH experiment, it is shown that antacids such as Maalox can be used effectively in neutralizing acidic stomach acid when used properly. There are variations in acidity in each and every beverage as shown in the chart. The closer a pH value of a beverage is to 7 (neutral), the less likely that someone will have and acidic stomach. Therefore, the less acidic the stomach condition, the less likely someone will need to use an antacid. There is justification to be concerned about harmful effects of misuse. Excessive amounts of antacids will cause the pH balance in the stomach to become basic in nature. If this is allowed to continue, too basic is just as

5 Cases of Confusion Between Things and Their Names

5 Cases of Confusion Between Things and Their Names 5 Cases of Confusion Between Things and Their Names 5 Cases of Confusion Between Things and Their Names By Mark Nichol 1. â€Å"Users can choose from any website that offers RSS feeds, short for ‘Really Simple Syndication.’ â€Å"RSS feeds† is not short for â€Å"Really Simple Syndication.† The sentence refers to RSS feeds and then explains what the initialism stands for, but the association of the spelled-out term with the initialism is confusing, so the additional information needs to be distinguished from the main point: â€Å"Users can choose from any website that offers RSS feeds. (RSS is short for ‘Really Simple Syndication.’)† More simply, the parenthesis could be introduced as here: â€Å"Users can choose from any website that offers RSS (Really Simple Syndication) feeds.† However, the information is not essential and is better introduced in a trailing parenthesis. Use your judgment according to the context of each case. 2. â€Å"This is a camera obscura, a Latin term that means ‘dark chamber.’† This sentence suffers from the same type of confusion as the previous example. A camera obscura is not a Latin term; it is a device with that Latin name (and though the origin of the name is Latin, the term, despite being taken from that language, is English). Revise the sentence to clarify both points: â€Å"This is a camera obscura, a device whose name, borrowed from Latin, means ‘dark chamber.’† 3. â€Å"The pre-emptive offer also a common term in corporate transactions is hardly new.† Here, the concept of the pre-emptive offer is being mistaken for the name of the concept. Again, word the interjection of information to clarify the distinction: â€Å"The strategy known as a pre-emptive offer that phrase is also a common term in corporate transactions is hardly new.† 4. â€Å"With his talkie debut, as British secret agent Bulldog Drummond (1929), he became the first silent star to become even bigger in sound films.† This sentence attempts to name both a character and a film in one designation, but as we all know from physics class, two phenomena cannot occupy the same space at the same time. Separate the reference to the title character from that of the film title: â€Å"With his talkie debut, as the titular British secret agent in Bulldog Drummond (1929), he became the first silent star to become even bigger in sound films.† 5. â€Å"John is a Wetland Watcher a moniker he wears with pride and satisfaction.† This sentence’s conflict of concept and name is not as jarring as in the previous examples, but the statement would nevertheless benefit from more of a separation of the two elements: â€Å"John is a Wetland Watcher, and that’s a moniker he bears with pride and satisfaction.† Want to improve your English in five minutes a day?

Aspects of Communication & Culture - Essay Example 63). Other people such as Stahl (2011, p. 1) and Goldkuhl (2003), among others, have different theories. This essay is an analysis of a telephone conversation between Michael and Prinze, based on communication analysis’ theoretical concepts and features of communication. Michael and Prinze’s Profile and their Background This is a telephone conversation between two close friends; Michael in his early fifties and Prinze in his late forties. One of the participants (Prinze) was observed throughout the recording for body language and gestures. These two interlocutors have known each other for more than ten years and share similar back grounds and interests. Also both interlocutors were born and have spent most of their lives in East London although their cultural and ethnic backgrounds are very different; Prinze is an English speaking cockney born and raised in London with a Pakistani parentage, whilst Michael is a native English speaking cockney. Each conversant is calling from the comfort of their home and from different towns; Mohammed lives in Luton and Michael in East London. Michael is recovering after a shoulder operation, whilst Prinze has just got home after a walk in the park. Both the interlocutors had not spoken or seen each other for more than a couple of months, but there had been regular communication between them by text messaging (SMS). The purpose of the call from Prinze to Michael was to get an update on how Michael was doing and also to discover if he had received the forwarded mail Prinze had sent him earlier. A transcription of the conversation between the two is given in the Appendix. Analysis Based On Theories and Main Communication Features Theories There are different theories of communication and theoretical concepts used in communication analysis. Just as noted Different authors have different views about these theories. Stahl has described nine categories of communication theories as listed by Little John (1999); cyberneti cs, semiotics, conversational analysis, message reception, socio-cultural approach, message production, symbolic interaction, phenomenological hermeneutics and critical theory (2011, p. 1). Littlejohn and Foss have eight theories; all described in the introduction (2007, p. 63). Goldkuhl (2003), on the other hand, considers the theories in the Language Action Perspective. The author notes that there are two theoretical concepts of communication representation approaches that are within the named perspective. These are; that there are predefined patterns in which communication is always organized as found in conversational analysis, and that language use can be considered as action as found in speech act theory (Goldkuhl, 2003, p. 51). In this case, two of the theoretical concepts will be explained with reference to Prinze and Michael’s conversation. These are; conversational analysis and speech act theory. Conversational Analysis It is the systemic analysis of human talk-in-i nteractions (Hutchby & Wooffitt, 2008). Conversational analysis’ theoretical concept is based on the view that conversations have predesigned structures. According to Psathas, telephone conversations open with a caller, who in this case, knows whoever he/she is calling. This is then followed by a response from the recipient who may know the caller or not. If the recipient does not know the caller, the next response will be
