  • On Root Modality and Thematic Relations in Tagalog and English*
    Proceedings of SALT 26: 775–794, 2016 On root modality and thematic relations in Tagalog and English* Maayan Abenina-Adar Nikos Angelopoulos UCLA UCLA Abstract The literature on modality discusses how context and grammar interact to produce different flavors of necessity primarily in connection with functional modals e.g., English auxiliaries. In contrast, the grammatical properties of lexical modals (i.e., thematic verbs) are less understood. In this paper, we use the Tagalog necessity modal kailangan and English need as a case study in the syntax-semantics of lexical modals. Kailangan and need enter two structures, which we call ‘thematic’ and ‘impersonal’. We show that when they establish a thematic dependency with a subject, they express necessity in light of this subject’s priorities, and in the absence of an overt thematic subject, they express necessity in light of priorities endorsed by the speaker. To account for this, we propose a single lexical entry for kailangan / need that uniformly selects for a ‘needer’ argument. In thematic constructions, the needer is the overt subject, and in impersonal constructions, it is an implicit speaker-bound pronoun. Keywords: modality, thematic relations, Tagalog, syntax-semantics interface 1 Introduction In this paper, we observe that English need and its Tagalog counterpart, kailangan, express two different types of necessity depending on the syntactic structure they enter. We show that thematic constructions like (1) express necessities in light of priorities of the thematic subject, i.e., John, whereas impersonal constructions like (2) express necessities in light of priorities of the speaker. (1) John needs there to be food left over.

  • General Physical Examination Skills for Ahps
    General Physical Examination Techniques for the Rheumatology Clinic This manual has been developed as an overview of the general examination of the rheumatology patient. Certain details have been specifically omitted because they have no relevance when examining a stable out patient in the rheumatology clinic. Vital Signs 1. Heart rate 2. Blood pressure 3. Weight 1. Heart Rate There are two things you want to document when assessing heart rate: The actual rate and the rhythm. Rate: count pulse for at least 15 – 30 seconds (e.g., if you count the rate for 15 seconds, multiply this result by 4 to determine heart rate). The radial pulse is most commonly used to assess the heart rate. With the pads of your index and middle fingers, compress the radial artery until a pulsation is detected. Normal 60-100 bpm Bradycardia <60 bpm Tachycardia >100 bpm 2. Heart Rhythm The rhythm should be regular. A regularly irregular rhythm is one where the pulse is irregular but there is a pattern to the irregularity. For example every third beat is dropped. An irregularly irregular rhythm is one where the pulse is irregular and there is no pattern to the irregularity. The classic example of this is atrial fibrillation. 3. Blood Pressure Blood pressure should be measured in both arms, and should include an assessment of orthostatic change How to measure the Brachial Artery Blood Pressure: • Patient should be relaxed, in a supine or sitting position, with the arms positioned correctly(at, not above, the level of the heart) • Remember that measurements should be taken bilaterally • Choice of appropriate cuff size for the patient is important to accuracy of measured blood pressure.

I know it won’t have everything that everyone wants but we are hopeful it will give people an idea of how the world of drugs is changing and highlight some of the key things that we think people can better engage with to keep themselves and those they care for safe. Once we cleaned the data from 150,000 people we chose to use data from just under 120,000 people this year for these reports. We have data reports addressing 18 different areas for over 25 countries. We can only share a fraction of what we have here on the site. However, we are very open to sharing the other findings we have and would ask researchers and public health groups to contact us so we can discuss funding and collaboration. We have almost completed designing GDS2018 so that we can start piloting early and give countries where we have not yet found friends to reach out to us. We particularly want to hear from people in Japan, Eastern Europe, Africa and the Middle East.

  • Blood Pressure (BP) Measurements in Adults
    Page 5 Blood Pressure (BP) Measurements in Adults Ramesh Khanna, MD Karl D. Nolph, MD Chair in Nephrology Professor of Medicine Director, Division of Nephrology University of Missouri-Columbia Uncontrolled high blood pressure is present in every 3rd person in the American community and is attributed to be a major risk factor for progression of chronic kidney disease, coronary artery disease, and stroke. Therefore, blood pressure recording is the most common measurements at home and by healthcare professionals in all of clinical medicine. It might come as a surprise that majority of recordings are done in a less than ideal circumstances and consequently performed inaccurately. BP measurements using mercury sphygmomanometer by a trained health care professional is the gold standard for clinical assessment of blood pressures. The appearance of the 1st Korotkoff sound signals the systolic blood pressure and the disappearance of the 5th sound denotes the diastolic blood pressure. The hypertension experts believe and have increasing evidence to suggest that this method frequently either over diagnose hypertension or fail to recognize masked hypertension (blood pressure that is normal in the physician’s office setting but high at other times including at home). The four commonly recognized reasons for this are: Avoidable inaccuracies in the methods, The inherent variability of blood pressure; and The tendency for blood pressure to increase in the presence of a health care professional (the so-called white coat effect). Failure to standardize blood pressure measurement dos and don’ts. It is believed and also to some extent evidence based that the health care providers including physicians often do not follow established guidelines for blood pressure measurement.

    Visual Metaphors on Album Covers: An Analysis into Graphic Design’s Effectiveness at Conveying Music Genres by Vivian Le A THESIS submitted to Oregon State University Honors College in partial fulfillment of the requirements for the degree of Honors Baccalaureate of Science in Accounting and Business Information Systems (Honors Scholar) Presented May 29, 2020 Commencement June 2020 AN ABSTRACT OF THE THESIS OF Vivian Le for the degree of Honors Baccalaureate of Science in Accounting and Business Information Systems presented on May 29, 2020. Title: Visual Metaphors on Album Covers: An Analysis into Graphic Design’s Effectiveness at Conveying Music Genres. Abstract approved:_____________________________________________________ Ryann Reynolds-McIlnay The rise of digital streaming has largely impacted the way the average listener consumes music. Consequentially, while the role of album art has evolved to meet the changes in music technology, it is hard to measure the effect of digital streaming on modern album art. This research seeks to determine whether or not graphic design still plays a role in marketing information about the music, such as its genre, to the consumer. It does so through two studies: 1. A computer visual analysis that measures color dominance of an image, and 2. A mixed-design lab experiment with volunteer participants who attempt to assess the genre of a given album. Findings from the first study show that color scheme models created from album samples cannot be used to predict the genre of an album. Further findings from the second theory show that consumers pay a significant amount of attention to album covers, enough to be able to correctly assess the genre of an album most of the time.

  • Danger Mouse's Grey Album, Mash-Ups, and the Age of Composition
    Danger Mouse's Grey Album, Mash-Ups, and the Age of Composition Philip A. Gunderson © 2004 Post-Modern Culture 15.1 Review of: Danger Mouse (Brian Burton), The Grey Album, Bootleg Recording 1. Depending on one's perspective, Danger Mouse's (Brian Burton's) Grey Album represents a highpoint or a nadir in the state of the recording arts in 2004. From the perspective of music fans and critics, Burton's creation--a daring "mash-up" of Jay-Z's The Black Album and the Beatles' eponymous 1969 work (popularly known as The White Album)--shows that, despite the continued corporatization of music, the DIY ethos of 1970s punk remains alive and well, manifesting in sampling and low-budget, "bedroom studio" production values. From the perspective of the recording industry, Danger Mouse's album represents the illegal plundering of some of the most valuable property in the history of pop music (the Beatles' sound recordings), the sacrilegious re-mixing of said recordings with a capella tracks of an African American rapper, and the electronic distribution of the entire album to hundreds of thousands of listeners who appear vexingly oblivious to current copyright law. That there would be a schism between the interests of consumers and the recording industry is hardly surprising; tension and antagonism characterize virtually all forms of exchange in capitalist economies. What is perhaps of note is that these tensions have escalated to the point of the abandonment of the exchange relationship itself. Music fans, fed up with the high prices (and outright price-fixing) of commercially available music, have opted to share music files via peer-to-peer file sharing networks, and record labels are attempting in response to coerce music fans back into the exchange relationship.
