Time Management in College
The document provides information on time management strategies for studying including comparing one's circadian rhythm to available study times, identifying "Swiss cheese" times to squeeze in work, eating frogs by doing the hardest tasks first to avoid procrastination, and using apps to countdown to exams. It includes charts on circadian rhythms and alertness throughout the day as well as statistics on time spent on social media and sending texts. The document aims to help students identify their optimal times to study and strategies to manage their time effectively.
ARTICLE 7. EXECUTIVE BRANCH
The document outlines the powers and duties of the Executive Branch in the Philippines according to Article 7 of the Philippine Constitution. It discusses that the executive power is vested in the President who enforces and administers laws. The President must be a natural born citizen at least 40 years old and resident in the Philippines for 10 years prior to election. The President serves a 6-year term and cannot be reelected. In the event of a vacancy, the Vice President assumes the presidency. The President has various powers including appointment with Commission on Appointments consent, removal, control of executive departments, and military powers like suspension of habeas corpus and declaration of martial law in times of invasion or rebellion.
How many dependent variables?
The document discusses dependent variables in statistics problems. It explains that the dependent variable is the "effect" side of a cause-and-effect relationship, or the "influenced" side of an influencer-influenced relationship. Several examples are provided to demonstrate how to identify the dependent variable in word problems involving research studies. The dependent variable is the main outcome or variable being measured in response to changes in other variables. Problems can have either a single dependent variable or multiple dependent variables.
How many independent variables?
The document discusses independent and dependent variables in statistics. It explains that the independent variable is the cause or influencer in a study, such as amount of study time or amount of sleep, while the dependent variable is the effect or what is being influenced, such as test scores. It provides examples of how to identify the independent and dependent variables in studies and word problems about viral infections, background noise, and more.
Scientific method procedures (Teach)
This is the second of a two part lesson on the scientific method. The earlier lesson was all about variables and this one focuses more on the procedures of the scientific method, at about the 5th and 6th grade level.
Dont get nervous
The document provides 10 steps to overcome nervousness before a test. The steps include taking deep breaths to calm down, practicing well to gain confidence, thinking positively, drinking water to prevent dry mouth, relaxing and not thinking about the test, pretending there is a reward after to look forward to the end, getting a good night's sleep, eating a healthy breakfast to boost brain function, doing some last minute revision, and being prepared for the test.
Chapter1 sections 5-9
The document discusses key concepts in biology, including:
1. Organizing species using a binomial nomenclature system consisting of genus and specific epithet names.
2. The importance of taxonomy and the Linnaean system for classifying organisms.
3. How scientists conduct experiments to test hypotheses and uncover cause-and-effect relationships, minimizing bias through experimental design and evaluating statistical significance of results.

Background How do we study primates Field primatologists.docx
Background: How do we study primates?
Field primatologists face a number of challenges. He or she must locate subjects, habituate them to the
presence of an observer without disrupting their natural behavior, and learn to recognize individual
animals from amongst a group. Only then can the primatologist begin "data collection" -- making behavioral
observations in a systematic way.
There are two problems: 1) you need to maintain objectivity as an
observer and not just watch the most "interesting" animal, and 2) it is impossible to see and record
everything, particularly if many primates are together in a group.
Therefore, all primatologists use
SAMPLING techniques to record their data. There are different types of sampling methods primatologists
employ.
For this assignment, we will use Scan Sampling. Based upon this technique, an animal's observed
behaviors are recorded at pre-selected moments in time (e.g., every 30 seconds). Instantaneous or scan
sampling is best achieved with a sample interval time as short as possible, and with behaviors that are very
easily identified. It is recommended that the observer create a list of possible behaviors, based upon
research, prior to beginning their fieldwork. When the observer is well prepared, this is an excellent
method for collecting a large amount of data on a group of animals.
It is only by collecting data systematically in this way that primatologists can describe and summarize the
complex behaviors of primates. Observation sampling lets primatologists measure natural behavior and
later address interesting comparative questions, such as:
How do primates spend their time? Do activity patterns vary with age or sex?
Are individuals equal in their social group, or is there a social ranking?
Do males and females compete for mates differently?
Do young animals learn anything while they are playing?
Are the young learning from adult males and females?
Assignment: Primatology Term Paper
The goal of this assignment is to study humans the way a primatologist works in the field and to help you
look at humans from a different perspective.
Pretend that you are a primatologist from another planet. You have just arrived on earth, and have taken
the physical form of a student. You are amazed by life among college students, and you are sure that it must
be different from the lives of other people. But most of your ideas about life off-campus come from either
watching TV, or from other strange settings, like the Starbucks or the mall. You begin to ask yourself, what
is human behavior really like?
Develop a comparative hypothesis about a simple behavioral question, and test it by collecting data on
samples of these earthlings. Note: YOU DO NOT UNDERSTAND ENGLISH... you will have to interpret human
behavior on the basis of what you see people doing, not on what you hear them say. Of course, actions often
speak louder than words.

Levels of Biological Organisation 4
The document describes a slideshow on levels of biological organization that includes a quiz. Students are asked to identify whether 15 pictures show a cell, tissue, organ, or system. The teacher then provides the answers to check the students' work.
Introduction to Hypothesis
This presentation discusses the following topics:
Meaning of Hypothesis
Sources of Hypothesis
Variables in hypotheses
Need for Hypothesis
Characteristics of Hypothesis
Functions of Hypothesis
Hypothesis vs. Theory
Variables in Hypothesis
Types of Hypothesis
Developing a Hypothesis
Parameters of Hypothesis
Checklist for Hypothesis
Examples
Sci Method Notes
The document outlines the scientific method process of stating a problem, making a hypothesis, designing an experiment, collecting data, and analyzing results. It uses the example of studying whether watching too much TV impacts brain activity. It guides walking through turning observations into a question, forming if-then hypotheses, designing a controlled experiment with variables, and considering sources of error when analyzing data. The goal is to gather accurate and precise quantitative or qualitative data to determine if the hypothesis is supported.
Experimental Hypothesis
The document describes an experiment that tested hypotheses about how different substances would interact with water. The experiment involved placing oil, vinegar, and laundry detergent into separate cups of water. The hypothesis for oil was that it would form a thin layer on top. This hypothesis was accepted when oil floated to the surface. The hypothesis for vinegar was that its presence would only be identifiable by smell, and this was accepted. The hypothesis for laundry detergent was that it would contaminate the water by changing the color and forming bubbles, and this was also accepted based on results.
Flowering Lesson All Slides
Flowering is an essential part of a plant's life cycle, and getting the timing and placement of flowering right can mean the difference between making lots of seeds for the next generation (success!) and none at all (EPIC fail). In this lesson, students will explore the genes that help Arabidopsis plants decide that it's time to make flowers. Once a plant makes the decision to flower, other genes must signal the right parts of the plants to develop into flowers. When this signaling is interrupted, very strange things can happen! In this lesson module, students will use current bioinformatics tools to build their understanding of how plants use their genes to respond to their environment.
202 Present Perfect Simple And Progressive
The document discusses the present perfect tense and present perfect progressive tense in English. It provides examples of how each tense is used, including to express actions that happened before now at an unspecified time, repetitive actions before now, and situations that began in the past and continue to the present. It also compares the present perfect to the simple past and discusses when to use the present perfect progressive versus the present perfect.
Hypothesis.pdf
A hypothesis represents what researchers predict will happen in an experiment based on more than a guess. It is a statement that can be tested scientifically. For a hypothesis to be valid, it must be a definite statement that can be checked through an experiment involving independent and dependent variables. Examples of valid hypotheses include "daily apple consumption leads to fewer doctor's visits" and "employees who have flexible working hours will report greater job satisfaction than employees who work fixed hours." The null hypothesis is usually that no significant change will occur in the dependent variable based on changes in the independent variable.

Michael Festing - MedicReS World Congress 2011
This document summarizes surveys that evaluated the statistical quality and design of published animal experiments. One survey found that 61% of papers would have required statistical revision, and 5% had errors so severe the conclusions were unsupported. A meta-analysis of 44 fluid resuscitation studies found substantial scope for bias and heterogeneity between results. Another study found poor agreement between animal responses and human outcomes for 3 of 6 interventions examined. A survey of 271 papers found many failed to clearly report important experimental details. Overall, the surveys suggest significant opportunities to improve animal experiment design and reporting.
Hypothesis formation
The document discusses key concepts for forming hypotheses in scientific experiments, including identifying the independent and dependent variables, control groups, and how to properly design experiments to test hypotheses. It provides examples of experiments and asks the reader to identify the independent variable, dependent variable, control group, possible conclusion, and how to improve the design for each. It emphasizes controlling all variables except the independent variable being tested.
Scientific method packet
Francesco Redi conducted an experiment in 1668 to test the idea of spontaneous generation, which was the belief that living things could come from nonliving things. Redi placed pieces of meat in jars, with some covered by cloth and others left uncovered. He observed maggots appearing only on the uncovered meat, supporting his hypothesis that maggots do not spontaneously generate from meat but rather come from eggs laid by flies. Redi's experiment provided evidence against the theory of spontaneous generation and helped establish the scientific method of testing hypotheses through controlled experiments.
Assignment 1BackgroundWhen you look around at the world, you .docx
Assignment 1:
Background
When you look around at the world, you can see many examples that demonstrate how an object's or a system's structure relates to its function. The structure of a highway system, for example, can affect traffic flow. You can, no doubt, think of many other examples.
In this Discussion Board assignment, you will look at the structure of the most basic unit of life, the living cell. You will also investigate how the structures of cells are directly related to the functions that are important to life.
Part 1
Your text describes the difference between the organelles in a eukaryotic cell and the more simple structure of a prokaryotic cell as an analogy between the chief executive officer's (CEO's) corner office and a cubicle. Organelles are like appliances or pieces of furniture that perform specific functions. Choose 1 organelle, and use an analogy to explain its function. For example, explain how a chloroplast is like a solar panel, or how a mitochondrion is like a furnace. Try to think of original analogies for other organelles or cell structures such as golgi, lysosome, cell wall, cell membrane, endoplasmic reticulum, ribosomes, nucleus, and so on. Include how your analogy may be less than perfect. Compare your analogy with those of your classmates’.
Part 2
You will read that only plants, algae, and some bacteria are photosynthetic. There is an exception to this, though. One species of sea slug has found a way to steal chloroplasts, store them in cells lining its digestive tract, and live on the sugar that is produced (Milius, 2010). What benefit would there be for animal cells (including those of humans) to make their own food? Could cell, tissue, or genetic engineering allow humans to use chloroplasts this way? Describe 1 or 2 factors that would need to be considered for chloroplasts to function in an animal or a human.
Reference
Milius, S. (2010). Green sea slug is part animal, part plant. Retrieved from http://www.wired.com/wiredscience/2010/01/green-sea-slug/
Assignment 2:
Scientific inquiry in biology starts by observing the living species around you. What separates science from the other methods of seeking truth is that it is testable (e.g., one can devise experiments to test the validity of an idea); it is falsifiable (e.g., an experiment can reveal if an idea is false); and it involves natural causality (e.g., the method involves and depends upon the natural laws of the universe which cause things to happen in a predictable and repeatable manner).
Observation: Scientific inquiry begins when something interesting gets your attention.
Question: Following an observation, a question arises in your mind. It may be something like "I wonder what?" or, "I wonder how? or, "I wonder why?"
Assignment Details
In this assignment, you will take a look at the scientific method. You will design a (fictional) scientific study to answer a specific question based upon an observation.
First, choose 1 of the following observations ...

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

Part 2
You will read that only plants, algae, and some bacteria are photosynthetic. There is an exception to this, though. One species of sea slug has found a way to steal chloroplasts, store them in cells lining its digestive tract, and live on the sugar that is produced (Milius, 2010). What benefit would there be for animal cells (including those of humans) to make their own food? Could cell, tissue, or genetic engineering allow humans to use chloroplasts this way? Describe 1 or 2 factors that would need to be considered for chloroplasts to function in an animal or a human.

Assignment 2:
Scientific inquiry in biology starts by observing the living species around you. What separates science from the other methods of seeking truth is that it is testable (e.g., one can devise experiments to test the validity of an idea); it is falsifiable (e.g., an experiment can reveal if an idea is false); and it involves natural causality (e.g., the method involves and depends upon the natural laws of the universe which cause things to happen in a predictable and repeatable manner).
Observation: Scientific inquiry begins when something interesting gets your attention.
Question: Following an observation, a question arises in your mind. It may be something like "I wonder what?" or, "I wonder how? or, "I wonder why?"
Assignment Details
In this assignment, you will take a look at the scientific method. You will design a (fictional) scientific study to answer a specific question based upon an observation.
First, choose 1 of the following observations ...

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.
ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
The cost of acquiring information by natural selection
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:
