Dr. Mari Golub gave a talk on how behavior is affected by iron deficiencies in the third trimester. The focus was looking at the hemo globin index, which is an iron protein that transports oxygen. Iron deficiencies are most common in children of preschool age and pregnant women. Golub explained a double-blind study done in 1993 by Ernesto Pollitt that studied if the effects on behavior by iron deficient could be reversed. There was three groups: anemic, iron deficient, and iron sufficient. They…

Inter-Observer Errors are critical in understanding the data as a whole. It’s to understand the error that comes with the interpretation of two or more individuals making observations of the same issue. This is a sole reason why scientists take multiple data sets in order to weed out these inter-observer errors. It can affect the end result, or calculation resulting in human bias. They are very similar, as my handedness quotient was 60 which is closer to 100 than to 0 (Ambi) which relates to…

Beside repeated questioning, another procedure that eyewitness most likely will have to go through is face identification. There has been a debate whether it is more accurate to identify suspect through photograph or in person. A study by Megreya and Burton examined the effect of method used in identification process (2008). The study consists of two experiments; experiment 1 assessed how accurate people can remember unfamiliar face immediately after the presence. The study involved 92…

Home Insurance FAQs 1. What does home insurance cover? Farmers Insurance- Homeowners insurance covers your home from the top of the roof to the pipes right down into the slab. Insurance also covers the contents of your house. If you theoretically take your house and turn it upside down, anything that falls out is also included in your coverage. 2. Can you provide some tips for estimating the value of my home? One simple way to determine the value of your home is to take the square…

Study Site We conducted this study at the Scientific Station at Las Joyas (Estación Cientifica Las Joyas) (19o35’20.7”N, 104o15’52.1”W) in the Sierra de Manantlán Biosphere Reserve, Jalisco, Mexico. Elevation reaches about 2400m above sea level. The forests transition from dry-deciduous, pine-oak, and cloud, as the elevation increases. Study Species We studied a white flowered plant with green berries and un-toothed leaves (most likely Solanum schlechtendalianum) from the genus Solanum, as it…

1. This experiment compared the spatial selective attention between “neurologically normal young adults” and split-brain subjects by measuring response times when presented unilateral and bilateral visual arrays. 2. The purpose for this experiment was to gather information about spatial selective attention, and to investigate whether “an independent focus of attention is deployed by each surgically separated hemisphere in a visual search task, such that bilateral stimulus arrays can be scanned…

Crime surveys and statistics are important because without it the government would have no information about unreported crimes. Surveys and statistics also recognise those most at risk of several types of crime. Also, it is used to collect data for crime prevention. It is a major source of information about levels of crime, public views to crime. The reality is that how diverse it is that the public is unware of the difficulty that in fact it is impossible to measure or count the actual…

Assign numbers to represent the batteries. I will assign the batteries in working condition the numbers 0-89 based on how they come off the production line in working condition 90% of the time. Next, numbers 90-99 will represent the defective batteries because of the 10%. Then, I’ll count by twos and move across the row. I’ll then count how many times working or defective batteries occur. A trial is when 10 working batteries are found. We will see how many batteries it takes on average to get…

Quantifying taxonomic proportions allows the individual to classify taxa in order to retain data on subsistence and paleoenvironmental reconstruction. As such, we will be discussing three different methods used for quantify taxonomic proportions are a) NISP (Number of Identified Specimens), b) MNI (Minimum Number Individuals, and c) bone weight. NISP (Numbered of Identified Specimens) allows researchers to obtain a number (or count) for each identified specimens. In other words, it is sorting…

Experiments are by definition in the glossary, “a deliberate manipulation of a variable to see if corresponding changes in behavior result, allowing the determination of cause and effect relationships”. To put this term in simple terms, we use experiments to purposely make changes in a study to get accurate results. In the hypothesis talking on a cell phone impairs driving skill it is highly important to follow the crucial protocol to make an efficient experiment. In an experiment there are two…
