The document discusses linear contrasts and comparisons in experimental design. It provides rules for constructing orthogonal coefficients to make independent comparisons between treatment groups. An example shows how to construct a table with orthogonal coefficients to compare the effects of phosphorus fertilization method (broadcast, shallow band, deep band), phosphorus rate (P1, P2), and their interaction on crop yield. Guidelines are given for calculating sums of squares, mean squares, and F-tests for each single degree of freedom contrast. A numerical example compares the effects of a protein supplement and sex on lamb weight gain ability.
This document discusses the use of nomograms to visualize relationships between three variables. It describes building a statistical model to predict donkey weight based on heart girth, height, age, and body condition score. A nomogram is presented that allows estimating weight from these other variables by drawing a straight line. The document also discusses extensions, such as adding other measurement types or donkey varieties to the nomogram.
This document summarizes a study that examined the neuroendocrine responses and autonomic nervous system activity in patients with postprandial distress syndrome (PDS) in response to acute mental stress. The study found that patients with PDS exhibited higher levels of stress hormones like adrenocorticotropic hormone (ACTH) and cortisol during mental stress compared to healthy controls. It also found that patients with PDS had increased sympathetic nervous system output, as measured by low/high frequency ratio, during and after meals when under mental stress. The enhanced stress response in patients with PDS may help explain how mental stress can worsen gastrointestinal symptoms in functional dyspepsia.
This document describes a student's term project analyzing a repeated measures dataset on rat body weights over time under different diets. The student builds several linear mixed models to analyze the data, starting with a basic fixed effects model with uncorrelated residuals, then improving the model by assuming correlated residuals within each rat. For the best fitting model, an unstructured covariance matrix is estimated to model the residual correlations decaying over time. Model selection is performed using information criteria and likelihood ratio tests.
1) Imperial Bank Limited is suing 20 defendants for fraudulently receiving over KES 34 billion from the bank without providing consideration or security.
2) The bank's former managing director colluded with the defendants and other bank officers to siphon the funds through manipulated accounts and transactions.
3) The bank, now under receivership, seeks urgent ex parte orders to freeze the defendants' assets in Kenya to prevent dissipation and protect depositors, as it investigates and pursues recovery of the stolen funds.
Using Anova to Evaluate Differential Protein Expressionheathermerk
This document describes using analysis of variance (ANOVA) to evaluate differential protein expression during flower senescence in petunias. Protein samples will be taken from pollinated and unpollinated petunia corollas at 0, 24, 48, and 72 hours and separated via two-dimensional gel electrophoresis. SAS will be used to analyze the gel images, including transforming the data to meet ANOVA assumptions, structuring the data for the model, and running a GLM procedure to identify significant effects of protein, treatment, time, and their interactions. The mean square error from the GLM will be used to calculate a least significant difference cutoff to objectively determine differential protein expression between treatments.
1. The document discusses Chi-square tests for categorical variables, including tests for goodness of fit, comparison of proportions between independent samples, and contingency tables.
2. Examples are provided to illustrate Chi-square tests for independence between binary variables, comparison of proportions between paired samples using McNemar's test, and tests on R×C contingency tables.
3. Pre-requisites for Chi-square tests are discussed, including minimum expected cell frequencies and using Fisher's exact test for small sample sizes.

Product Design Trends in 2024 | Teenage EngineeringsPixeldarts
The realm of product design is a constantly changing environment where technology and style intersect. Every year introduces fresh challenges and exciting trends that mold the future of this captivating art form. In this piece, we delve into the significant trends set to influence the look and functionality of product design in the year 2024.
How Race, Age and Gender Shape Attitudes Towards Mental HealthThinkNow
Mental health has been in the news quite a bit lately. Dozens of U.S. states are currently suing Meta for contributing to the youth mental health crisis by inserting addictive features into their products, while the U.S. Surgeon General is touring the nation to bring awareness to the growing epidemic of loneliness and isolation. The country has endured periods of low national morale, such as in the 1970s when high inflation and the energy crisis worsened public sentiment following the Vietnam War. The current mood, however, feels different. Gallup recently reported that national mental health is at an all-time low, with few bright spots to lift spirits.
To better understand how Americans are feeling and their attitudes towards mental health in general, ThinkNow conducted a nationally representative quantitative survey of 1,500 respondents and found some interesting differences among ethnic, age and gender groups.
Technology
For example, 52% agree that technology and social media have a negative impact on mental health, but when broken out by race, 61% of Whites felt technology had a negative effect, and only 48% of Hispanics thought it did.
While technology has helped us keep in touch with friends and family in faraway places, it appears to have degraded our ability to connect in person. Staying connected online is a double-edged sword since the same news feed that brings us pictures of the grandkids and fluffy kittens also feeds us news about the wars in Israel and Ukraine, the dysfunction in Washington, the latest mass shooting and the climate crisis.
Hispanics may have a built-in defense against the isolation technology breeds, owing to their large, multigenerational households, strong social support systems, and tendency to use social media to stay connected with relatives abroad.
Age and Gender
When asked how individuals rate their mental health, men rate it higher than women by 11 percentage points, and Baby Boomers rank it highest at 83%, saying it’s good or excellent vs. 57% of Gen Z saying the same.
Gen Z spends the most amount of time on social media, so the notion that social media negatively affects mental health appears to be correlated. Unfortunately, Gen Z is also the generation that’s least comfortable discussing mental health concerns with healthcare professionals. Only 40% of them state they’re comfortable discussing their issues with a professional compared to 60% of Millennials and 65% of Boomers.
Race Affects Attitudes
As seen in previous research conducted by ThinkNow, Asian Americans lag other groups when it comes to awareness of mental health issues. Twenty-four percent of Asian Americans believe that having a mental health issue is a sign of weakness compared to the 16% average for all groups. Asians are also considerably less likely to be aware of mental health services in their communities (42% vs. 55%) and most likely to seek out information on social media (51% vs. 35%).
AI Trends in Creative Operations 2024 by Artwork Flow.pdfmarketingartwork
Creative operations teams expect increased AI use in 2024. Currently, over half of tasks are not AI-enabled, but this is expected to decrease in the coming year. ChatGPT is the most popular AI tool currently. Business leaders are more actively exploring AI benefits than individual contributors. Most respondents do not believe AI will impact workforce size in 2024. However, some inhibitions still exist around AI accuracy and lack of understanding. Creatives primarily want to use AI to save time on mundane tasks and boost productivity.
Organizational culture includes values, norms, systems, symbols, language, assumptions, beliefs, and habits that influence employee behaviors and how people interpret those behaviors. It is important because culture can help or hinder a company's success. Some key aspects of Netflix's culture that help it achieve results include hiring smartly so every position has stars, focusing on attitude over just aptitude, and having a strict policy against peacocks, whiners, and jerks.
PEPSICO Presentation to CAGNY Conference Feb 2024Neil Kimberley
PepsiCo provided a safe harbor statement noting that any forward-looking statements are based on currently available information and are subject to risks and uncertainties. It also provided information on non-GAAP measures and directing readers to its website for disclosure and reconciliation.

Components of an effective methodology include defining objectives and KPIs, audience analysis, identifying opportunities, and evaluating resources. The document concludes with recommendations around creating a content plan, testing and optimizing content over 90 days.
How to Prepare For a Successful Job Search for 2024Albert Qian
The document provides guidance on preparing a job search for 2024. It discusses the state of the job market, focusing on growth in AI and healthcare but also continued layoffs. It recommends figuring out what you want to do by researching interests and skills, then conducting informational interviews. The job search should involve building a personal brand on LinkedIn, actively applying to jobs, tailoring resumes and interviews, maintaining job hunting as a habit, and continuing self-improvement.

Google's Just Not That Into You: Understanding Core Updates & Search IntentLily Ray
1. Core updates from Google periodically change how its algorithms assess and rank websites and pages. This can impact rankings through shifts in user intent, site quality issues being caught up to, world events influencing queries, and overhauls to search like the E-A-T framework.
2. There are many possible user intents beyond just transactional, navigational and informational. Identifying intent shifts is important during core updates. Sites may need to optimize for new intents through different content types and sections.
3. Responding effectively to core updates requires analyzing "before and after" data to understand changes, identifying new intents or page types, and ensuring content matches appropriate intents across video, images, knowledge graphs and more.

The six step guide to practical project management
If you think managing projects is too difficult, think again.
We’ve stripped back project management processes to the
basics – to make it quicker and easier, without sacrificing
the vital ingredients for success.

1. LINEAR CONTRASTS OR COMPARISONS
In planning an experiment, we can often provide for F tests to answer pertinent questions.
This involves partitioning the df and TRT SS.
Skillfully selected treatments can answer as many independent questions as there are TRT df.
When comparisons are independent, they are said to be orthogonal.
Advantages of Linear Contrasts
1. They enable one to answer specific, important questions about treatment effects.
2. The computations are simple.
3. They provide a useful check on the TRT SS.
Orthogonal Coefficients
Linear contrasts involve the selection of orthogonal coefficients.
Comparisons for coefficients are constructed using the following rules.
1. If two groups of equal size are to be compared, assign coefficients of +1 to the members
of one group and -1 to those of the other group. It does not matter which group is
assigned the positive coefficient.
2. In comparing groups containing different numbers of treatments, assign to the first group,
coefficients equal to the number of treatments in the second group, and to the second
group, coefficients of the opposite sign equal to the number of treatments in the first
group.
3. Reduce coefficients to the smallest possible integers. For example, in comparing a group
of two treatments with a group of four, by rule 2, the coefficients are +4,+4,-2,-2,-2.
These can be reduced to +2,+2,-1,-1,-1,-1.
4. Interaction coefficients can always be found by multiplying the corresponding
coefficients of the main effects.

2. For comparisons to be orthogonal (i.e., independent), the following must be true:
1. The sum of the coefficients must equal zero (i.e., Eci=0.)
2. The sum of the product of the corresponding coefficients of any two comparisons is zero
(i.e., Ecici'=0).
An Example to show how to construct a table of orthogonal coefficients.
Suppose an experiment is planned to test the efficiency of phosphorus fertilization by three
methods: broadcast (B), shallow band placement (S), and deep placement (D). Also, for each
one of these methods of placement, two rates of phosphorus will be applied (P1, and P2). A
nonfertilized treatment will be included (NT) to establish a response of the fertilizer.
Step 1. List the treatments across the top of the table.
Step 2. Write in the comparison coefficients as you decide what comparisons will be made.
There will be t-1 comparisons.
Comparison NT P1B P1S P1D P2B P2S P2D
Response to P 6 -1 -1 -1 -1 -1 -1
P1 vs P2 0 1 1 1 -1 -1 -1
B vs S+D 0 2 -1 -1 2 -1 -1
S vs D 0 0 1 -1 0 1 -1
(P1 vs P2)x(B vs S+D) 0 2 -1 -1 -2 1 1
(P1 vs P2)x(S vs D) 0 0 1 -1 0 -1 1
Description of Comparisons
1. Is there a response to P. (NOTE: Having made a comparison involving a single trt
compared with all the rest, NT cannot be used again if the comparisons are to be
orthogonal.)
2. Is the average response to P2 greater than that of P1?.
3. Over both levels of P, is band placement superior to broadcast?
4. Considering band placement only, is there a difference between shallow and deep?
5. Is the change in yield from P1 to P2 different for broadcast compared to band placement?
6. Is the change in yield from P1 to P2 different for shallow compared to deep band
placement.

3. In the above table, note that coefficients of all rows sum to zero and that the sum of the
coefficients for the same treatments for any two comparisons sum to zero.
For each single degree of freedom contrast, a sum of square, mean square, and an F-test
can be calculated.
SS = (EcYi.)2/(rEci2) = Q2/rk
where: c = coefficients
Yi. = Treatment totals
r = number of replicates
Q = (EcYi.)2
k = Eci2
Numerical Example
A study is conducted to investigate the effect of a protein supplement on male and female lamb
weight gain. There are four treatments:
P0S0 No protein supplement, male lamb
P0S1 No protein supplement, female lamb
P1S0 Protein supplement, male lamb
P1S1 Protein supplement, female lamb
We can ask three pertinent questions.
1. Considering all lambs, does the protein supplement affect weight gain ability?
2. Irrespective of protein supplement, are there differences in gaining ability between male
and females?
3. Does the protein supplement have the same affect on weight gain ability in male and
female lambs?

4. Step 1. Calculate correction factor
CF = (EYij)2/rt = 9282/4x4 = 53,824
Step 2. Calculate Total SS
Total SS = EYij2 - CF = 334
Step 3. Calculate Replicate SS
Rep SS = Y.j2/t - CF = 1.5
Step 4. Calculate Treatment SS
Trt SS = Yi.2/r - CF = 208.0
Step 5. Calculate Error SS
Error SS = Total SS - Rep SS - Trt SS = 124.5
Step 6. Partition Treatment SS into single df contrasts
P0S0 P0S1 P1S0 P1S1
Trt Totals 228 212 252 236
Protein supplement vs. No protein supplement +1 +1 -1 -1
Male lambs vs. Female lambs +1 -1 +1 -1
Protein supplement x Sex of lambs +1 -1 -1 +1
i. Write coefficients
ii. Calculate SS for each single df Comparison

SS Sex = [(1)228 + (-1)212 + (1)252 + (-1)236]2 = 64
4[(1)2 + (-1)2 + (1)2 + (-1)2]
SS Protein x sex [(1)228 + (-1)212 + (-1)252 + (1)236]2 = 0

Considering all lambs, addition of a protein supplement significantly increased weight gaining
ability.
2) n Mean
Male 8 60.0
Female 8 56.0
Considering both diets together, there was no significant difference in weight gaining ability
between males and females.
n Mean

Female, no supplement 4 53.0
Male, supplement 4 63.0
Female, supplement 4 59.0
Male and female lambs responded similarly in weight gaining ability to the addition of a protein
supplement to their diet.
