Degree-Day Summation and Hatching of the Forest Tent Caterpillar, \u3ci\u3eMalacosoma Disstria\u3c/i\u3e (Lepidoptera: Lasiocampidae)

(excerpt) The forest tent caterpillar, Malacosoma disstria (Htibner), is a common defoliater of deciduous trees throughout most of the United States and Canada. It is a well known outbreak species, whose populations erupt periodically (every 10 to 16 years) when forest conditions are suitable. Typical outbreaks last three to six years in a given geographic area and then collapse as quickly as they arise. This note documents the relation between forest tent caterpillar egg hatching in the field and heat accumulation (degree-days) leading up to hatch. This information will permit (a) predicting the date on which eggs will hatch by summing degree days during the insect\u27s overwintering period, and (b) comparing with populations in other years and areas. The data came from an outbreak in northern Minnesota that began near International Falls in 1966 and collapsed in 1972 (Witter et al., 1975)

Internalized Racism: A Theoretical Model

Internalized racism exists, we can observe and measure the effect it has on people. It manifests from both the psychological and sociological factors that form a person’s racial self-image. As Campón and Carter (2015) state: “less attention to date has been given to … how racial minority groups appropriate (i.e., take in) racial beliefs.” (p.498). In this dissertation, I explore how internalized racism forms. Further, I propose a new theoretical model integrating two concepts, the racialized self and racialized experiences. Racism is found at different levels, within the self through the racialized self, it highlights how People of Color view themselves through a racially framed lens, as well as racist experiences from people and institutions. Combining sociological and psychological theoretical developments in internalized racism research, I explore these relationships amongst the racialized self, racialized experiences, and internalized racism. Using an original self-reported survey, data was collected using Amazon’s Mechanical Turk and Prolific to explore how the racialized self and racialized experiences manifest among People of Color, then analyze their causal relationship with internalized racism. I find that the racialized self and racialized experiences significantly associate with internalized racism. While not all relationships are in the predicted direction, this dissertation shows that not only is there evidence for the existence of the racialized self and racialized experiences, but that both concepts aid in the formation of internalized racism

An Investigation of Some Quinoline and Acridine Derivatives of Possible Therapeutic Value

In this thesis, some new acridine and quinoline ethene derivatives are described, and these compounds will now be considered in detail. Each series has been confined to a separate section for the sake of clarity, and each of these sections is, as far as possible, complete in itself. In Section I, a series of anil coxapounds of 2:8-diamino acridine is discussed, while sections It, III, and IV are concerned chiefly with a series of ethene derivatives prepared from 5-aldehyde acridine. Thus Section II contains pyridine-acridine ethenes of type (a), while Section III deals with analogous quinoline-acridine ethenes of type (b). (a) In Section IV an unsuccessful attempt was made to prepare acridine-acridine ethenes of the following type. The means whereby substituent groups can be introduced into the acridine ring of the ethene compounds prepared are also briefly discussed in this section. In addition to the compounds mentioned above, a few quinoline ethene and anil derivatives of the type studied by Browning and his collaborators have been prepared. The theoretical portion of this thesis has been reserved largely for discussions of a general nature, results of biological tests, and consideration of negative results or cases of especial difficulty arising out of the preparation of the various compounds studied. It contains therefore, little information on the methods of preparation employed, since this is available in extensons in the experimental section, together with any relevant theoretical considerations

Some correlations between hypnotic action and chemical constitution

A review of theories of narcosis has been made, and some correlations between constitution and activity have been presented for the aliphatic hypnotics;The close and important relationship of dibenzofuran and its derivatives to morphine has been discussed. The following derivatives to morphine has been discussed. The following derivatives to morphine has been discussed. The following derivatives of dibenzofuran haven been prepared for use in physiological tests: 2-, 3-, and 4-amino-, 2- and 3-hydroxy-dibenzofuran, and 2- and 3-dibenzofurancarboxylic acids;A necessary study of nuclear substitution in dibenzofuran has been made prior to the preparation of derivatives for physiological tests. It has been shown that homonuclear substitution results when 2-discetaminodibenzofuran is brominated or nitrated. Heteronuclear substitution occurs when 3-nitrodibenzofuran is brominated. Both heteronuclear and homonuclear substitution take place when 2-bomodibenzofuran is nitrated;The hydroxydibenzofuran formed by passing resorcinol over heated tungstic oxide has been shown to be 3-hydroxydibenzofuran; and, a low melting isomer formed during nitration of dibenzofuran has been found to consist, in part, of 2-nitrodibenzofuran. The significance of these two facts is discussed with reference to the space formula of dibenzofuran and purported anomalous substitutions

Does the evaluability bias hold when giving to animal charities?

When evaluating a charity by itself, people tend to overweight overhead costs in relation to cost-effectiveness. However, when evaluating charities side by side, they base their donations on cost-effectiveness. I conducted a replication and extension of Caviola et al. (2014; Study 1) using a 3 (High Overhead/Effectiveness, Low Overhead/Effectiveness, Both) x 2 (Humans, Animals) between-subjects design. I found that the overhead ratio is an easier attribute to evaluate than cost-effectiveness in separate evaluation, and, in joint evalution, people allocate decisions based on cost-effectiveness. This effect was observed for human charities, and to a lesser extent, for animal charities
