And Behavior

This exploratory study investigates how emerging adults (EAs) experience catching feelings. Applying the Stages of Change Model and Relational Receptivity Theory, this study investigates how EAs understand the cognitive and behavior changes leading up to commitment and how they process precontemplation surrounding catching feelings. Using focus group interviews, collegiate EAs ( N = 17) define catching feelings as the unintentional, unexpected, and surprisingly desirable development of romantic feelings for another person (commonly beginning face-to-face). When confronted with catching feelings, EAs must delineate their preconditions for catching feelings and work through decision-making processes. Implications for relationship readiness, communication, and commitment are discussed.

AbstractThe number of Medetera aldrichii Wheeler adults emerging daily in 1966 and 1967 was low and irregular. Peak numbers apparently emerged 20–30 days prior to mass emergence of Dendroctonus ponderosae Hopkins although the numbers fluctuated through the mass emergence period of the beetle. Densities of emerging adults averaged less than 1 per square foot of bark and never exceeded 6.0 per square foot. Densities of the emerging flies and beetles did not appear related.Adults mated on the bark surface of trees infested with D. ponderosae; mating habits are described.Females oviposited in degenerate resin ducts in the bark surface. Two eggs per duct were the modal number. Seven or more per duct were found in less than 5% of the ducts examined.

Prototypes are defined as the image a person holds of the typical person who engages in risk behavior and are comprised of favorability toward the prototype and similarity to the prototype. Despite both being posited as important prototype dimensions, the findings regarding their predictive utility are mixed, and most research has focused on alcohol use and not other related risk behaviors. Thus, the present study examined whether both prototype dimensions (prototype favorability, prototype similarity) as well as their interaction predicted alcohol and alcohol-related sexual cognitions and behavior. Results from 294 emerging adults indicated that prototype similarity (but not prototype favorability or their interaction) predicted both behavioral and cognitive outcomes. Results suggest that researchers utilizing prototypes should be mindful of which prototype dimensions they include in their guiding theory and subsequent clinical applications.

Suicide Plan

Rates of suicidal ideation and behavior are high and increasing in emerging adulthood. Research focused on suicidal ideation as a predictor of suicidal behavior has nearly exclusively conceptualized suicidal ideation as verbal thoughts about suicide. Emerging research suggests, however, that mentally imagining suicide may be even more impairing than verbal thoughts about suicide. Thirty-nine emerging adults with a lifetime history of suicidal cognitions completed self-report assessments of characteristics of their suicidal cognitions, histories of suicide plans and behavior, and the degree to which their suicidal cognitions took the form of mental imagery or verbal thought. Suicidal mental imagery predicted more intense and longer duration of suicidal cognitions, a higher likelihood of having made a suicide plan, and a higher likelihood of having made a suicide attempt over and above suicidal verbal thoughts. Thus, suicidal mental imagery could provide a novel target for suicide assessment and intervention for emerging adults.

Marital Behavior

This chapter examines the role marriage plays in the life planning and behavior of emerging adults. Most emerging adults hold marriage in positive regard and plan to get married at some point. As emerging adults age, however, finances, career development, education, and job availability lead them to flexibly shift their “marital horizons” and become more open to marital alternatives, such as remaining single or cohabitating. Emerging adults are getting married later and are also remaining single in increasing numbers. Although the dominant cultural model of marriage is one that promotes individual growth and self-actualization, there is an emerging class divide. Partners are expecting more from marriage while investing less time in their partners. New models for marital behavior and expectations may be needed to address why some marriages are more satisfying than ever before, while a great number are falling short, encumbered by individual, cultural, and structural considerations.

AbstractThe target article by Boyer & Petersen (B&P) contributes a vital message: that people have folk economic theories that shape their thoughts and behavior in the marketplace. This message is all the more important because, in the history of economic thought, Homo economicus was increasingly stripped of mental capacities. Intuitive theories can help restore the mind of Homo economicus.

Abstract We identify the significance and typical requirements of developmental analyses of the microbiome-gut-brain (MGB) in parents, offspring, and parent-offspring relations, which have particular importance for neurobehavioral outcomes in mammalian species, including humans. We call for a focus on behavioral measures of social-emotional function. Methodological approaches to interpreting relations between the microbiota and behavior are discussed.

There is extensive interest in SiGe for use in heterojunction bipolar transistors. SiGe/Si superlattices are also of interest because of their potential for use in infrared detectors and field-effect transistors. The processing required for these materials is quite compatible with existing silicon technology. However, before SiGe can be used extensively for devices, there is a need to understand and then control the origin and behavior of defects in the materials. The present study was aimed at investigating the structural quality of, and the behavior of defects in, graded SiGe layers grown by chemical vapor deposition (CVD).The structures investigated in this study consisted of Si1-xGex[x=0.16]/Si1-xGex[x= 0.14, 0.13, 0.12, 0.10, 0.09, 0.07, 0.05, 0.04, 0.005, 0]/epi-Si/substrate heterolayers grown by CVD. The Si1-xGex layers were isochronally grown [t = 0.4 minutes per layer], with gas-flow rates being adjusted to control composition. Cross-section TEM specimens were prepared in the 110 geometry. These were then analyzed using two-beam bright-field, dark-field and weak-beam images. A JEOL JEM 200CX transmission electron microscope was used, operating at 200 kV.

High-pressure oxidation of silicon (HIPOX) is one of various techniques used for electrical-isolation of semiconductor-devices on silicon substrates. Other techniques have included local-oxidation of silicon (LOCOS), poly-buffered LOCOS, deep-trench isolation and separation of silicon by implanted oxygen (SIMOX). Reliable use of HIPOX for device-isolation requires an understanding of the behavior of the materials and structures being used and their interactions under different processing conditions. The effect of HIPOX-related stresses in the structures is of interest because structuraldefects, if formed, could electrically degrade devices.This investigation was performed to study the origin and behavior of defects in recessed HIPOX (RHIPOX) structures. The structures were exposed to a boron implant. Samples consisted of (i) RHlPOX'ed strip exposed to a boron implant, (ii) recessed strip prior to HIPOX, but exposed to a boron implant, (iii) test-pad prior to HIPOX, (iv) HIPOX'ed region away from R-HIPOX edge. Cross-section TEM specimens were prepared in the <110> substrate-geometry.
