Presentation

Challenges

• Speaking to a camera

• Time delay when switching views

• Language accessibility

• Resolution of transmitted material– font size – complexity of material– slide format

Page 3: Giving a Multidisciplinary Video Conference Presentation

Font Size:

14 pt is typical

28 pt minimumIf using 28 pt, Bold Helps

32-36 pt preferred

32-36 pt preferred

Page 4: Giving a Multidisciplinary Video Conference Presentation

Use Plain Bold Fonts

Other: Probes to bacterial transcripts (28pt Arial Bold)

Other: Probes to bacterial transcripts (28pt Arial)

Other: Probes to bacterial transcripts (28 pt Times New Roman Bold)

Page 5: Giving a Multidisciplinary Video Conference Presentation

Probe Type

Discovery: Genes of interest for particular species

Positive: Probes to bacterial transcripts that are spiked into total RNA

Negative: Probes to bacterial transcripts that are not spiked into the total RNA and are used for negative control threshold calculation

Other: Probes to bacterial transcripts that are neither part of the negative control threshold calculation nor the positive controls

Fiducials: Controls that the software package uses to grid the array.

Quality Flags

Good: No flags associated with this particular spot.

Empty: Spots near a background level where the mean background plus one standard deviation is greater than the signal mean.

MSR: Data points not provided (blank cell in excel worksheet) based upon quality control of manufacturing processes. Each array is scanned post-dispense and issues such as misfiring are labeled as MSR.

Poor: Spots identified based upon characteristics such as spot morphology or large interference in signal (such as a speck of dust).

Negative: Spots with an signal mean less than the background; intensity value is a negative number.

Typical presentation: 14 pt

Problems with Previous Slide

• Text too small

• Too much information

• Margins too small

• Language too complicated

Page 7: Giving a Multidisciplinary Video Conference Presentation

Probe Type

Discovery: Genes of interest for particular species

Positive: Probes to bacterial transcripts that are spiked into total RNA

Negative: Probes to bacterial transcripts that are not spiked into the total RNA and are used for negative control threshold calculation

Other: Probes to bacterial transcripts that are neither part of the negative control threshold calculation nor the positive controls

Much easier to read: 28 ptBut still too complicated

Page 8: Giving a Multidisciplinary Video Conference Presentation

Discovery: Genes of interest

Positive: Probes spiked into RNA

Negative: Probes not spiked into RNA

Less complicated, Larger marginsMakes point more effectively

Page 9: Giving a Multidisciplinary Video Conference Presentation

Use Plain Contrasting Backgrounds

Page 10: Giving a Multidisciplinary Video Conference Presentation

Other: Probes to bacterial transcripts that are neither part of the negative control threshold calculation nor the positive controls

Use Plain Contrasting Backgrounds

Page 11: Giving a Multidisciplinary Video Conference Presentation

Other: Probes to bacterial transcripts that are neither part of the negative control threshold calculation nor the positive controls

Use Plain Contrasting Backgrounds

Black text on a plain white background has so much contrast it does not

project well.

Page 12: Giving a Multidisciplinary Video Conference Presentation

Other: Probes to bacterial transcripts that are neither part of the negative control threshold calculation nor the positive controls

Use Plain Contrasting Backgrounds

A light coloured background helps but still has a high contrast.

Page 13: Giving a Multidisciplinary Video Conference Presentation

Other: Probes to bacterial transcripts that are neither part of the negative control threshold calculation nor the positive controls

Use Plain Contrasting Backgrounds

Standard light yellow on dark blue works well

-As part of a pharmacogenetics project, we screened exons and flanking intronic regions for variation in a set of 24 membrane transporter genes (96 kb; 57% coding) in 247 DNA samples from ethnically diverse populations.

-We identified 680 Single Nucleotide Polymorphisms (SNPs), of which 175 were synonymous and 155 caused amino acid changes, and 29 small insertions and deletions.

-Amino acid diversity (NS) in transmembrane domains (TMDs) was significantly lower than in loop domains, suggesting that TMDs have special functional constraints.

-underlying assumption was that alleles that are functionally deleterious will be selected against and thus under represented at high frequencies and over represented at low frequencies.

-Green People had an excess of high frequency alleles in comparison to Blue People, consistent with a historic bottleneck. In addition, Blue People exhibited a much higher frequency of population specific medium-frequency alleles than did GreenPeople.

Another Bad Slide

Page 15: Giving a Multidisciplinary Video Conference Presentation

Limit Page Content

Increase font size, Allow margins

Reduce content

Use no more that 6-8 lines per page

Allow no more that 4-5 major points per page

Remove jargon

Page 16: Giving a Multidisciplinary Video Conference Presentation

- screened for inherited mutations in 24 genes from ethnically diverse samples

-680 mutations were identified

-155 of these caused amino acid changes

-assumption was that alleles that are functionally bad will be selected against

-Green people had more mutations than Blue

Simplifying Content can make it easier to present

Avoid Animations

Moving Towards a New EraMolecularly targeted therapies

• Studies have shown that behind every type of cancer cells there is a unique set of abnormal molecules that help with their survival and growth.

• We are also studying ways to specifically inactivate these molecules.

Material that Projects Poorly

• gel • Flourescent image

Page 30: Giving a Multidisciplinary Video Conference Presentation

If you must include complicated figures

• Give a copy of the powerpoint file to Cay or Kathryn the day before

• We will make and distribute copies

• Does not have to be the entire presentation

Page 31: Giving a Multidisciplinary Video Conference Presentation

Summary-1

• Simplify content

• Avoid jargon

• Use 28 pt Arial bold as a minimum

• 6-8 lines of text per page

• 4-5 points per page

• Use a plain contrasting background

Page 32: Giving a Multidisciplinary Video Conference Presentation

Summary-2

• Avoid animation• Avoid detailed or complicated figures

or pictures

• Do not use scanned material• Bring presentation on a CD that is

finalized (closed)• RELAX
