Article Critique #3 - Essay Example Nine of the articles have only â€Å"maternal† or â€Å"mother† in the title, though most of the other references refer to â€Å"father,† â€Å"paternal,† or â€Å"men.† A total of 7,601 men completed questionnaires for the study, a large study to say the least. The researchers assessed children at 3  ½ and 7 years of age, and data were compared for children whose fathers reported prenatal or postnatal depression (or both). The researchers theorized that exposure to father depression even before birth can affect the behavior of the child, even if the depression itself clears up. Although more than 7,000 total questionnaires were completed, only 175 reported prenatal-only depression, 166 reported postnatal-only, and 89 reported both. The results of comparing these three groups together with the controls (never depressed) show that both prenatal and postnatal depression in fathers causes children higher levels of behavior problems later in life, usually conduct disorders, and fathers who reported depression at both times were even more likely to have children with behavior problems. The researchers broke the data on the children into boy and girl sets. Their findings show that both postnatal depression and pre- and postnatal depression caused boys behavior problems, but interestingly the prenatal only group of children exhibited conduct problems but not emotional or overall problems. The findings for girls were less statistically significant, but the analysis showed that girls exposed to depression also had more conduct problems than girls who were not exposed to paternal depression. Basically, it is clear that boys exposed to their father’s depression, even if it is just prenatally, exhibit behavior problems in later life more than boys who are not exposed to paternal depression. The study is limited by the broad nature of the population (7,601 total) and the small number of men reporting depression (430

Hydrocodone (Vicodin) Essay Example | Topics and Well Written Essays - 500 words

Hydrocodone (Vicodin) - Essay Example This medicine should not be taken with the Alcohol or CNS depressant as it very dangerous from health point of view. Hydrocodone may be habit forming. Patients should stop using as soon as the prescribed period got over. The generally reported adverse reactions are faintness, wooziness, sedation, queasiness and vomiting. These effects seem to be more prominent in those who are working while in people who stays idle may experience severe reactions. Other adverse reaction might include different reactions on the central nervous system (mood swings, fear, lethargy etc), Gastrointestinal System (constipation), Respiratory System (respiratory depression), Special Senses (hearing can be damaged) and Dermatological (allergic reactions like rashes etc) As for the contraindications, this medicine should never be used by those patients who have a record of exhibition to hypersensitivity to hydrocodone or acetaminophen. As patients who are known to be hypersensitive to any opioids, may exhibit cross-sensitivity to hydrocodone. Reaction of Vicodin is related to how Hydrocodone and acetaminophen works in the body.

The Positivism And Interpretivism Philosophy Essay

The Positivism And Interpretivism Philosophy Essay The book of Business Research Methods gives me guidance for how to do business studies and how to carry out research project. In the first part of the book tells me the relationship between theory and research, in the detail its a explain of how to combine the theory and research during the business studies process. (Page: 4) 1a. What is meant by epistemological considerations? Epistemological concerns the study of knowledge and what constitutes acceptable knowledge in a field of study? Epistemology is a kind of using the same principles, procedures, and ethos as the natural sciences study to explore the nature of human knowledge, structure, the relationship of recognizing the objective reality, the premise and basis of knowledge. The position that affirms the importance of imitating the natural sciences is invariably associated with an epistemological position known as positivism. (Page: 15) 1b. Explain in concrete terms the differences between the so-called positivism and interpretivism? Positivism: (Page: 15-1.7) Positivism is a kind way of epistemological position that claims to use the natural sciences methods to study and beyond of reality society. In the book, there are some principles of using positivism. Positivisms principles: 1. Only phenomena and hence knowledge confirmed by the senses can genuinely be warranted as knowledge (the principle of phenomenalism). 2. The purpose of theory is to generate hypotheses that can be tested and that will thereby allow explanations of laws to be assessed (the principle of phenomenalism). 3. Knowledge is arrived at through the gathering of facts that provide the basis for laws (the principle of phenomenalism). 4. Science must (and presumably can) be conducted in a way that is value free (that is, objective). 5. There is a clear distinction between scientific statements and normative statements and belief that the former are the true domain of scientist. This last principle is implied by the first because the truth or otherwise of normative statements cannot confirmed by the senses. Interpretivism: (Page: 16) Interpretivism is a term given to a contrasting epistemology to positivism. It is necessary for the research to understand differences between humans in our role as social actors. There are differences between conducting research among people rather than physical objects. To enter the social world of our research subjects, understand their world from their point of view. (Page: 16) Interpretivism arose as scientists felt that human beings were not puppets to react to stimuli in a prescribed manner. They were active and purposeful and can respond to stimuli in different ways depending upon their interpretation. Interpretivists describe human beings as having intent and the power to interpret;they say that human beings have the capability to construct their surroundings rather than being a mere spectators to what is happening around them. These scientists stressed the thinking, intentions and behaviors of human beings more than positivists thereby drawing conclusions that were more realistic and perhaps more valid also. Interpretivists talk about shared consciousness as the brain behind many of the concepts in a society. 2a. What is meant by ontological considerations? Ontological considerations: (Page: 20) Questions of social ontology are concerns with the view on nature of reality, the study of nature of existence. The core question of this part is whether the social entity can and should be considered objective entities which have the truth external to social actors, or whether they can and should be considered social constructions built up from the perceptions and actions of social actors. (Bryman 2004: 16) These positions are frequently referred to respectively as objectivism and constructionism. 2b. Explain in concrete terms the differences between objectivism and constructionism? Objectivism: (Page: 21 1.13) Objectivism is an ontological position that asserts that social phenomena and their meanings have an existence that is independent of social actors. It implies that social phenomena and the categories that we use in everyday discourse have an existence that is independent or separate from actors. Constructionism: (Page: 22 1.14) Constructionism is an ontological position (often also referred to as constructivism) which asserts that social phenomena and their meanings are continually being accomplished by social actors. It implies that social phenomena and categories are not only produced through social interaction but that they are in a constant state of revision. Objectivism and constructivism is diametrically opposite assumptions about reality, mind, thought, meaning and symbolism. The objective belief is that the world is real. The reality is the external awareness. Since it is sees the world as real it assumes that learners have the same understanding of this reality. The reality can be structured model to guide a learner. Constructivist perspective requires learners to create their own reality based on his experiences and views. The constructivist point that not a reality. Because the reality is a product of personal views and experiences are unique individuals many reality can exist. The objectivism think the role of the mind as a processor of abstract symbols thought of as symbols of the builders of the Constructivist perspectives. Objectivism sees the role of the mind as a processor of abstract symbols while constructivism views the mind as a builder of symbols. Relationship of epistemology and ontology to business research (Page: 23) Every science has its own ontology, epistemology and consequently its own methodologies. So when the business research Ontology defines the fundamental categories of reality. Domain ontology as distinct from formal ontology is related to focus of study. Each research field has its own ontology. Epistemology defines how we can know and reason that reality. The methodologies of each of these two scientists have followed as different systems of investigative techniques within their focus of study. They use different scientific methods studying different domains with different epistemology and ontology.

How childhood history and culture affects how we live as adults Essay

Childhood history has a lot to do with how we live as adults because certain childhood events could trigger something that would last a life time. Take for example if a child fails at something and the parent does nothing to help the child, the child will grow up thinking that failing is alright and that he or she will have a hard time in life with their job or in school or life in general. Many events from a persons’ life can stick with the person throughout their life like a thorn in the side. The event will every so often reappear in the persons mind when some event in the present triggers a familiarity with the past event and the person could go in to a state of worry or even worse shock. In this occurrence it could immobilize the person and result in a lackluster in th...

Process Analysis and Capacity Management Essay

1. Dello is a world-class PC company. Management believes that they understand their products and customers better than any outsourcing company; therefore Dello should provide customer service in-house. Ideally, Dello’s customer service department wants to handle all the customer phone calls. During peak hours, however, Dello receives so many customer calls that they ask an outsourcing company, Telemate, to help handle incoming calls. Dello’s switchboard system is programmed in the following way; A customer calls Dello at its 1-800 number. If there are 14 or less callers in the system waiting to speak with one of the customer service representatives, then the call stays within Dello’s system and the customer inquiry will be answered by a Dello customer service representative. If, on the other hand, there are 15 or more calls waiting within Dello’s system, then the incoming call is forwarded to the outsourcer Telemate, and the call will be answered by a Tel emate agent. Draw the process flowchart for Dello’s customer service call handling process. [pic] 2. Getaway is another computer company known for mass customization. Its secret is to always maintain an inventory of base models, and to offer its customers add-on options. The process is as follows: The first step is receiving the order. After receiving an order, the order is checked for add-ons. If needed, add-ons are added to the base model. (Note that base models are held in inventory). Then the computer is packed, and finally shipped. Draw a process flow diagram for the above process. [pic] If you want to be stricter, you can have triangles for add-on parts inventory and work-in-process between packing and shipping. 3. Kate is managing his company’s production facility. Consider the following production process. Note: some triangles may be intentionally omitted. [pic] Raw materials go through machines A, B, and then C, to produce a final product. Capacity, or service rate, of each machine is as follows: Machine A: 200 units per hour Machine B: 180 units per hour Machine C: 120 units per hour (All these numbers are expressed in terms of units of final product.) a) Identify the bottleneck process. Is it A, B, or C? Explain briefly. Machine C, since it’s the slowest process of all. Kate sincerely believes that she must keep high utilization of machines. Every time she sees an operator idle, therefore, she orders the operator to go back to the machine and continue operating. b) What is she doing wrong? What is the most likely result if she manages the factory this way? She doesn’t seem to understand that the bottleneck process defines throughput of the entire system. In other words, the production facility can process just as fast as the bottleneck. If she tells every operator to produce all the time, most likely result is that she will have unnecessarily large WIP built-up between machines. 4. Eastern Coffee follows the flow chart below to serve its customers. Note that some triangles may be omitted intentionally. It takes a worker two minutes to take order and receive payment, two minutes to prepare coffee, and three minutes to clean equipment. Eastern Coffee has two workers: worker A takes order and prepares coffee, while worker B handles the cleaning. a) On average, 10 customers per hour show up and order coffee. What is the utilization rate of worker A? And what is the utilization rate of worker B? Capacity of worker A: 60/(2+2) = 15 customers/hour Capacity of worker B: 60/3 = 20 customers/hour Utilization of A: 10/15 = 0.666 or 66.6†¦% Utilization of B: 10/20 = 0.5 or 50% b) How many customers can Eastern Coffee serve per hour? From the above, Capacity of Eastern Coffee is 15 customers/hour Western Coffee follows the same flow chart above, and each activity takes the same amount of time as Eastern. Western Coffee also has two workers: worker C only takes order and payment, while worker D handles the coffee preparation and cleaning. c) How many customers can Western Coffee serve per hour? Capacity of worker C: 60/2 = 30 customers/hour Capacity of worker D: 60/(2+3) = 12 customers/hour Capacity of Western Coffee is 12 customers/hour d) The manager of Western Coffee notices that cleaning is not a critical activity in the sense that it can be delayed and be finished when there are fewer customers. Therefore, during the peak hour when many customers come in, workers can focus on serving customers and temporarily ignore the cleaning activity. Then how many customers can Western Coffee serve during the peak hour? Capacity of worker D during the peak hour: 60/2 = 30 customers/hour Capacity of Western Coffee is 30 customers/hour 5. At Spotted Cow Coffee Shop, one cashier can take 30 orders per hour and one skilled worker can prepare 20 orders per hour. Assume that the cashier and the worker are not cross-trained. a. Suppose that there are only one cashier and one worker in Spotted Cow. What is the capacity of Spotted Cow? And which resource is the bottleneck? Explain. The worker is the bottleneck as she pushes the smallest amount of job in an hour. The capacity of Spotted Cow is 20 orders per hour, which is decided by the bottleneck. b. Suppose that Spotted Cow hires one more skilled worker who can also prepare 20 orders per hour. What is the capacity of Spotted Cow? And which resource is the bottleneck? Explain. The cashier is the bottleneck as she can take at most 30 orders per hour. While the two workers can prepare in total 40 orders per hour. The capacity of Spotted Cow is 30 orders per hour, which is decided by the bottleneck. 6. Pavich’s Brick Oven Pizza is known for its speedy delivery time of piping hot pizza. Its secret is to always maintain an inventory of uncooked, assembled, cheese pizzas, and to offer its customers only cheese and pepperoni pizza. If a customer orders a cheese pizza, uncooked cheese pizza goes immediately into the oven. If a customer orders a pepperoni pizza, pepperoni is added to the cheese pizza, and then the pizza is cooked, and finally delivered. Draw the process flowchart diagram for Pavich’s Brick Oven Pizza. In your flowchart, use at least two inverted triangles. [pic] You can of course have an arrow from uncooked cheese pizza inventory to cooking process. 7. Campus Credit Union has 5 representatives, 2 of them specialized in business customers and 3 of them specialized in personal customers. On average, each business customer takes 15 minutes, and each personal customer takes 12 minutes to finish the service. During the 4-5pm rush hour, 10 business customers and 10 personal customers show up. a. Does the Credit Union have enough capacity during the rush hour? Each hour, a representative can serve 60/15=4 business customers and 60/12=5 personal customers. During the rush hour, the capacity for business customers is 4*2=810. The Credit Union will have enough capacity for all the customers. 8. The following flow chart describes a simple burger making process. [pic] One stove is available to cook patties. It can cook patties in 3 minutes and holds 40 patties at one time. On average, it takes 45 seconds for a worker to assemble a burger. There are 12 workers available to assemble. The time it takes to deliver can be omitted. Assume that one burger needs only one patty. a. What is the capacity of the cooking stage? What is the capacity of the assembly stage? What is the capacity of the entire process? The stove can cook 40*60/3 = 800 patties per hour. The workers can assemble 12 * 60 / 0.75 = 960 burgers per hour. The stove is the bottleneck. The capacity of the entire process is 800 burgers per hour. b. Suppose that on average 600 burgers per hour are ordered from customers. What is the utilization rate of the stove? What is the utilization rate of the worker, on average? Utilization rate of the stove: 600 per hour / 800 per hour = 75% Utilization rate of the workers, on average: 600 per hour / 960 per hour = 62.5%. 9. A small medical center would like to determine the capacity requirements for the next month. Currently there are 11 doctors working 8 hours a day and 5 days a week. They provide care for three types of patients: patients come for regular check-ups (type A), patients with minor problems (type B), and patients with serious problems (type C). The management had estimated the number of patients for the next four weeks as follows: | |Weekly numbers of patients | | |Week # 1 |Week # 2 |Week # 3 |Week # 4 | |Type A |250 |50 |100 |500 | |Type B |150 |300 |150 |300 | |Type C |200 |150 |250 |150 | All the doctors can provide care for all types of patients. Type A patients require 15 minutes of care, type B patients require 30 minutes of care, and type C patients require 60 minutes of care. a. What are the average utilization rates of the doctors for each of the next 4 weeks? Requirements in # hours | |Number of hours needed | | |Week # 1 |Week # 2 |Week # 3 |Week # 4 | |Type A |62.5 |12.5 |25 |125 | |Type B |75 |150 |75 |150 | |Type C |200 |150 |250 |150 | |Total |337.5 |312.5 |350 |425 | |Utilizations |76.7% |71.0% |79.5% |96.6% | Total available doctors time = 11*8*5 = 440 hours b. Does this medical center have enough capacity? Yes 10. A clothing company produces 5 types of shirts (A, B, C, D, and E). The final manufacturing steps in the shirt production process are to (a) attach a care label to every shirt, and (b) brand the company’s name on every shirt. The company has one machine for attaching care labels, and one machine for branding. For any shirt type, branding requires 8 minutes of processing on the machine. Due to differences between shirt designs, attaching care labels requires the following shirt-dependent processing times (in minutes): Shirt Type Processing Time A 4 B 10 C 5 D 6 E 8 The demand per day for the different shirt types is: Shirt Type Demand A 20 B 5 C 25 D 10 E 15 Assume each machine is available to work 8 hours per day. Does the company have the capacity to satisfy its demand? Explain your answer fully. The demand for the branding machine is: (20 + 5 + 25+ 10 + 15) * 8 = 600 minutes, or 600/60 = 10 hours. There is not enough capacity on the branding machine to satisfy demand. This machine is a bottleneck resource. The demand for the label attaching machine is: 20 * 4 + 5 * 10 + 25 * 5 + 10 * 6 + 15 * 8 = 435 minutes, or 435 / 60 = 7.25 hours. There is enough capacity on the label attaching machine to satisfy demand. 11. InnovB is a call center company. InnovB has a highly sophisticated switchboard system called Virtual Agent that takes customer calls. There are 20 telephone lines and therefore 20 Virtual Agents. Virtual Agent asks a caller some basic questions such as the caller’s preferred language, account number, etc. On average, a customer spends 3 minutes within Virtual Agent system. Depending on the nature of the transaction and customer’s account history, Virtual Agent puts a call through to either a high-skilled or a low-skilled customer service representative (CSR). Virtual Agent is programmed so that all difficult calls are handled by high-skilled CSRs, and all the easy calls are handled by low-skilled CSRs. It takes, on average, 6 minutes for a high-skilled CSR to process a difficult call, and it takes 4 minutes for a low-skilled CSR to take care of an easy call. There are 15 high-skilled and 20 low-skilled CSRs. At the end of the transaction, both difficult and easy cal ls are transferred to the company’s customer satisfaction survey system. It takes on average 2 minutes to take the survey. Since there are 20 telephone lines, there can be up to 20 callers taking the survey at one time. a. Draw the process flowchart diagram for InnovB. Use at least one inverted triangle. Use only one rectangle for the â€Å"survey† process. Use arrows, not lines. Yes No b. Can InnovB handle 125 difficult calls per hour? Explain. Capacity of Virtual Agent= 20*20 = 400 customers/hr Capacity of high skilled = 10*15 = 150 customers/hr Capacity of low skilled = 15*20 = 300 customers/hr Capacity of survey system = 30*20 = 600 customers/hr Yes, 125 is possible.

Hunting Snake and Cockroach Essay

The poems â€Å"Hunting Snake† and â€Å"The Cockroach† are very different but also vastly similar poems. The predominant language feature that is common in both poems is an extended metaphor – this is used in â€Å"Hunting Snake† to represent the colonisation of the Aborigines in Ancient Australia, and in â€Å"The Cockroach† to represent human nature, values and the way we live our lives. The poem â€Å"Hunting Snake† is obviously a poem about a group of people coming across a snake, staring in awe at its beauty and dissimilarity and then moving on. Wright uses a lot of sibilance in this poem, perhaps to emphasise the snake. However if we explore deeper we notice that the poem is not about this at all – in fact it has an exceptionally different meaning. The entire poem is an extended metaphor for the colonisation of the Aborigines in Australia – the snake represents the Aborigines and the persona represents the colonisers. Although the colonisers saw the incredibly beautiful and unique Aborigines, they simply looked at each other and walked on – this is exactly what happens during every colonisation. The colonisers do not think about anyone else’s feelings, just their own personal or monetary gain. Hunting Snake is a poem about ancient beliefs and values, and the way that humans acted many years ago. In comparison, the poem â€Å"The Cockroach† is also one that addresses the issue of human nature and values. Kevin Halligan uses a cockroach to portray a ‘disgusting’ creature, one that many people are eager to kill and get rid of. Cockroaches also have a very nomadic lifestyle – they scurry about from place to place, never settling down and are always â€Å"on the go†. Halligan wishes for us to compare the cockroaches’ lifestyle with our own – the scampering motion of the bug is a reflection of his (and all humans’) nomadic lifestyle. By describing these frantic movements he is saying something about how most of us live our lives and our incapability to settle down – we are all in a hurry to move on to the next chapter in our lives, the next milestone, the next day, month, or year. This poem is set in modern day, it is written as if the cockroach is inside a house or a building, not outside like Hunting Snake. This technique helps to give us a better understanding of the poem – we can more easily relate it to human nature and our own lifestyles.
