Soil as a 3-Phase Material and Soil Classification (100 marks) Dredging is the scooping up of soils from the bottom of the waterways for land reclamation purposes or to keep rivers, canals, basins and channels clear of underwater obstruction. Dredging is also a critical element where marine piling needs to be set in place to enable quick commencement of steelwork and civil engineering construction projects. A dredging project has been proposed by a local council to dredge X(m) long section of a 12m wide canal up to a depth of 1.8m to reclaim land for the construction of a recreation centre. The material pumped out of the canal is described by data obtained from a sieving and compaction test as shown in Table 1 and Table 2 respectively. If the in-situ unit weight of the soil at the bottom of the canal is 22kN/m3 and the soil material is being pumped at a rate of 0.3m3 per minute. Take the specific gravity of the soil grains as 2.7 and X as the last three digits of your student ID (SID) number. Take X = 450m if last 3digits of your SID number is less than 300

PSY 2230E Adolescent Development ONLINE
Fall 2019
Article Summary Assignment
This assignment meets Course Learning Outcome 3 of 4: Given a prescribed format, students will read and summarize an adolescent development research article.
Bloom’s Taxonomy Requirements: Comprehension, Analysis, Evaluation
APA Standards Addressed:
-Identify principal methods and types of questions that emerge in specific content domains. (APA 1.2b)
-Demonstrate psychology information literacy (APA 2.2)
-Read and summarize general ideas and conclusions from psychological sources accurately. (APA 2.2a)
-Describe research methods used by psychologists including respective advantages and disadvantages. (APA 2.4a)
-Express ideas in written formats that reflect basic psychological concepts and principles. (APA 4.1a)
DO NOT worry about having to “do” what is listed above. By completing this assignment, you will be demonstrating skills in the areas above. This information box is provided simple as a reminder that your work on this assignment does serve a purpose.
Reading a research article can be very challenging for a variety of reasons, particularly as a student. These articles are written by experts for other experts rather than for novices or students. In psychology, our published research articles follow a standard format: abstract, introduction, methods, results, discussion.
 The abstract is a very brief summary of the entire project, including the aims and results.
 The introduction sets the stage for the rest of the article and requires a great deal of higher level thinking to develop (analysis and evaluation of individual research articles and synthesis into the new idea or approach taken in the current article). In the introduction, the authors discuss research relevant to their current pursuit and present the prior research in a manner that develops a rationale for their study. This rationale guides everything else that follows. This section is VERY useful to students.
 The methods section describes every detail of the current study, from the participants to any materials used to any decisions about study design (e.g. longitudinal or cross-sectional). This section is most useful for other researchers looking to replicate or extend the findings of the current article.
 The results section contains a lot of statistics. Scientists use statistical manipulation of data to help determine the effects of what they are investigating. Psychology students learn about basic statistics as undergraduates, but research articles often employ statistical measures and processes with which students are unfamiliar. As such, this section is once again largely for other researchers.
 The discussion section presents an interpretation of the results. This section requires evaluation and synthesis as well because the current findings must be examined in light of previous findings and with respect to the rationale set out for the study. This section is also VERY useful to students.
Unfortunately, most students approach reading research articles as they would a textbook chapter, starting at the first page and attempting to read all the way through to the end. The problem with that approach is that students often get lost in the methods and results sections, losing sight of the connections between the introduction and discussion. Even experts don’t read articles this way. Personally, I start with the abstract, of course, but then I often go straight to the discussion to see what they are concluding, particularly if I am familiar with pervious work in the target area. If I am less familiar, I read the introduction before the discussion. Once I am clear on why they conducted the study and what they claim to have found, I go back and read the methods and results.
Fortunately, for this assignment, I’m going to ask you to read an article differently than you might think, and the process I am suggesting will be very useful to you as educators. I am literally giving you permission to skip
the results sections outright when you read research articles as professionals, and the methods sections will be areas that you skim after the fact if you need clarification about the participants, assessment measures, or any other details that can be found in the methods section (but only after you have read the abstract, introduction, and discussion).
The article that you have been assigned is Decreases in Psychological Well-Being Among American Adolescents After 2012 and Links to Screen Time During the Rise of Smartphone Technology (Twenge, Martin, & Campbell, 2018). This article is a multi-study article because it contains two experiments in one paper. So, there is a general introduction, but then each study has a brief introduction to explain the purpose of each study. Each study also has a discussion section, followed by a general discussion section at the end of the paper. The assignment prompt and grading specs reflect this format.
To read the article, you are going to do the following (and take notes for yourself throughout – trust me on this one):
1. Read the title carefully to try to make sense of what you are about to read.
2. Read the abstract VERY carefully (multiple times if you have to) so that you get the gist of what they were after before you try to read the larger sections of the article.
3. Read the introduction so that you can understand the relevant research and how the authors have used it to formulate their rationale for conducting the experiment(s) you will be reading about.
4. Read the introduction and discussion for Study 1.
5. Read the introduction and discussion for Study 2.
6. Read the general discussion to determine what they found and whether their findings were in line with their expectations. You should also be looking for how the authors cycle back to the main points in the introduction to see if they close the loop and discuss how their study fits in with the previous findings that they reviewed in the intro. One last thing to look for is a consideration of the limitations of the study and future directions.
In your summary, you must address the following:
1. What is the purpose of the article, including the specific purposes and rationales of each of the two studies that were conducted? If you need help here, try to determine what questions the authors were trying to answer with their research.
2. What did they find? How are their findings significant? Do they align their findings with what they presented in the introduction? Do they discuss next steps?
3. Reflect upon how/why this article is relevant to you as an educator of adolescents.
Your summary should be typed, double-spaced, and approximately 3-4 pages in length. Writing mechanics do count, so please be mindful of your spelling, grammar, and punctuation. Please refer back to the article by citing appropriately (e.g. Twenge et al., 2018) when you do. If you are unsure of when to cite, err on the side of caution (a good rule of thumb is to cite anything that is not common knowledge). Do not use quotes – make sure everything is in your own words. Your work will be graded according to the grading specifications on the next page. You must meet all specs to pass this assignment. If you do not, you will have the opportunity to revise and resubmit for full credit.
Grading Specs General purpose is explained clearly and accurately. Rationale/purpose of each study is explained clearly and accurately. Findings are explained clearly and accurately. Reflection upon application of the article to educator practice is evident and sound. Student statements are supported by evidence from the article. Citations are present when necessary. Bloom’s Taxonomy: Comprehension has been demonstrated reasonably. Bloom’s Taxonomy: Analysis of the reasoning in the article has been demonstrated reasonably. Writing mechanics are sound and errors do not impede reader’s ability to easily comprehend the content.

ORGANIZATION THEORY (MGMT A477)

Please answer ALL questions. You may refer to the textbook and related slides before composing your response to each question. Please restrict each answer within 200 words. You must provide examples to exemplify the quality of your responses. Please type your answers as clearly as possible. You must avoid spelling and grammatical errors. Your answers will be graded based on the originality and clarity of your composition. Lastly, please do not copy directly from textbook, internet or other resources.

ESSAY QUESTIONS (3 X 25 points = 75 points)

  • “Modernists see clear boundary between the organization and its environment whereas Symbolic-interpretivists see a more fluid boundary between the organization and its environment.” Please analyze the above statement using appropriate organizational theories (such as structural contingency theory, resource dependence, population ecology, and institutional theory).
  • Taking McDonalds as an example, what are/do you think are the dimensions of organizational structure and how do these relate to the environment? Do you think McDonalds has mainly organic or mechanistic characteristics and are these appropriate? (Hint: This question connects Chapter 3 and 4).
  • From a post-modernist perspective, identify and briefly explain at least three issues that tall organizations encounter in comparison to flat organizations. (Hint: You need to think from management/employee/customer side to identify the issues).

 

How would you operationally define the subcategories for Type of Claim? For example, what counts as a fat type of claim?

/in /by

Content Analysis Activity

Research Question: What types of health claims are most frequently used on the front of cereal boxes?

Unit of Analysis: claim

Categories for Type of Claim: For each specific brand, you should count the number of each type of health claim on the box and put the total number for each category in the coding sheet. The categories include fat-related, sugar-related, fiber-related, protein-related, and vitamin/mineral-related.

How to Code: One strategy you could use is to start at the top and work your way down the box, one claim at a time. So, find the first health-related claim on the box, determine which category it fits into, and put a one into the correct box. Keep adding in the appropriate categories until you’ve gone through all of the claims. Some claims may not fit into a category. If that’s the case, you just don’t code that claim (although keep it in mind to answer the questions that follow).

Coding Scheme:

Specific Brand (sample text) Type of Claim (unit of analysis) Number of Claims
Frosted Flakes
Fat
Sugar
Fiber
Protein
Vitamin/Mineral
Special K
Fat
Sugar
Fiber
Protein
Vitamin/Mineral
Kix
Fat
Sugar
Fiber
Protein
Vitamin/Mineral

 

Questions:

  1. How might you change the coding scheme? Would you add additional coding categories? Would you create more specific/different subcategories for the existing coding category (Type of Claim) than those that currently exist? Be sure to thoroughly and clear explain your answers as well as include arguments for the changes that you propose.

 

  1. How would you operationally define the subcategories for Type of Claim? For example, what counts as a fat type of claim? What counts as a sugar type of claim? Also, what counts as a claim more generally? Would you stick to only text or would both text and visuals be included in the definition of a claim? Be sure to thoroughly and clearly explain your answers as well as include arguments for the changes that you propose.

* It can be argued that multiculturalism is more than a policy description.  It could be an ideology used to inform and guide Canadian society. Multiculturalism prescribes a set of ideas and ideals consistent with the principles of cultural pluralism and modeled after the liberal virtues of freedom, tolerance and respect for the individual.
