Hail to Thee, Our Alma Mater: Alumni Role Identity and the Relationship to Institutional Support Behaviors

With the decline in state and federal support for higher education continuing to plague colleges and universities across the U.S., many institutions are looking to increase the levels of support annually received from alumni and other constituencies. Research on alumni relations in American colleges and universities has historically focused on different factors related to charitable giving. Although this study has resulted in some valuable information for institutions to use for alumni involvement purposes, most of the research has not been able to produce a meaningful look into how alumni identify with their college or university after graduation. The purpose of this study is to assess how college and university alumni view their role with these institutions after graduation and how that perception relates to behaviors of support. An online survey was constructed to assess three dimensions of alumni role identity based upon previous research on the identification process of blood donation. This study took place through the alumni association at a large, public research university in the Midwest and found that those who displayed increased alumni role identity were more likely to support the university through joining the alumni association, attending university sponsored events and charitable giving. This study breaks ground for a new method of measuring the role of alumni within colleges and universities in efforts to increase support and ease the financial pressures of today’s institutions.     

The Influence of Communication Apprehension on Superiors' Propensity for and Practice of Participative Decision Making

This investigation examined if traitlike communication apprehension (CA) serves as a significant predictor of superiors' propensity for and practice of participative decision making (PDM)—that is, involving others in decision-making processes. A total of 219 superiors recruited from a variety of organizations served as participants in this study. Results revealed that traitlike CA is a significant determinant of variation in superiors' inclination for, as well as their actual practice of, PDM. These findings suggest that superiors with lower CA possess favorable perceptions of PDM and are more inclined to involve others in decision-making processes than their colleagues with higher CA. Conversely, results suggest that superiors with higher CA typically possess less favorable perceptions of PDM and are less likely to involve others when making decisions. Theoretical and practical implications underpinning these results are explored. Future research directions are also proposed.     

Single nanopore transport of synthetic and biological polyelectrolytes in three-dimensional hybrid microfluidic∕nanofluidic devices

This paper presents a study of electrokinetic transport in single nanopores integrated into vertically stacked three-dimensional hybrid microfluidic∕nanofluidic structures. In these devices, single nanopores, created by focused ion beam (FIB) milling in thin polymer films, provide fluidic connection between two vertically separated, perpendicular microfluidic channels. Experiments address both systems in which the nanoporous membrane is composed of the same (homojunction) or different (heterojunction) polymer as the microfluidic channels. These devices are then used to study the electrokinetic transport properties of synthetic (i.e., polystyrene sulfonate and polyallylamine) and biological (i.e., DNA) polyelectrolytes across these nanopores using both electrical current measurements and confocal microscopy. Both optical and electrical measurements indicate that electro-osmotic transport is predominant over electrophoresis in single nanopores with d>180 nm, consistent with results obtained under similar conditions for nanocapillary array membranes.     

Piracy as Statecraft: The Mediterranean Policies of the Fifth/Eleventh-Century Taifa of Denia

The taifa of Denia on the Iberian eastern seaboard was one of the most dynamic of the regional polities that emerged from the disintegrated Cordovan caliphate. Mujāhid al-‘āmirī based his state not only on its continental territories, but especially on the maritime networks that linked it with the Mediterranean. Commerce with Muslim and Christian ports played a role in Denia's success, but both Latin and Arabic sources emphasise its practice of piracy on a grand scale. In fact, Mujāhid al-‘āmirī built his state as a continuation of the maritime policies of the Cordovan caliphate under which the piracy of independent coastal communities was adopted and expanded into a state-sponsored guerre de course. Mujāhid's pursuance of this policy stemmed from his role in the erstwhile caliphate, but was also motivated by a combination of religious, political and economic factors. The legitimacy provided by his “jihād on the sea” helped to shore up his power at a time of political instability. This policy also provided the taifa's economic foundation for much of its history. In fact, the Mediterranean maritime lanes became as much an extension of Denia as its continental territories. Denia's piracy thus reflects a coherent form of statecraft, informing definitions of the medieval state and territoriality.     

Intertrial unconditioned stimuli differentially impact trace conditioning

Three experiments assessed how appetitive conditioning in rats changes over the duration of a trace conditioned stimulus (CS) when unsignaled unconditioned stimuli (USs) are introduced into the intertrial interval. In Experiment 1, a target US occurred at a fixed time either shortly before (embedded), shortly after (trace), or at the same time (delay) as the offset of a 120-s CS. During the CS, responding was most suppressed by intertrial USs in the trace group, less so in the delay group, and least in the embedded group. Unreinforced probe trials revealed a bell-shaped curve centered on the normal US arrival time during the trace interval, suggesting that temporally specific learning occurred both with and without intertrial USs. Experiments 2a and 2b confirmed that the bulk of the trace CS became inhibitory when intertrial USs were scheduled, as measured by summation and retardation tests, even though CS offset evoked a temporally precise conditioned response. Thus, an inhibitory CS may give rise to new stimuli specifically linked to its termination, which are excitatory. A modification to the microstimulus temporal difference model is offered to account for the data.     

A reexamination of the effects of motivational state on utilization of conspecific odors in the rat

Two previous studies suggested that rats are unable to use conspecifics’ odors when the motivational state of the donor rats is different from their own (Davis et al., 1974; Davis, Prytula, Noble, & Mollenhour, 1976). The effects of motivational conditions on the utilization of such odors were further evaluated in the present study. In Phase 1, test rats were given training either with donors in the same motivational state or with donors in a different state. Differential responses to donors’ odor emissions occurred only when the motivational states of donors and test subjects were the same, thus confirming earlier findings. However, when test subjects’ motivational conditions were changed in Phase 2, discriminations that had been present in Phase 1 were maintained even though the motivational states of these test subjects and their respective donors no longer matched. Thus, any constraint on the rat’s ability to use odors from conspecifics in a different motivational state is not absolute.     

Explaining parental coviewing: The role of social facilitation and arousal

This study explores the relationship between parental coviewing and children’s psychophysiological responses to television exposure within a framework of social facilitation. A total of 88 children aged 6–13 years and one of each of their parents participated in a 2 (presence or absence of the parent)?×?2 (exciting or non-exciting TV content) between-subjects experiment. Results indicated that the presence of a coviewing parent was associated with an increase in children’s arousal (higher skin conductance levels) and cognitive resource allocation (lower heart rate), especially for younger children who came from homes where parental coviewing was a relatively frequent activity. These findings suggest that the mere presence of a coviewing parent is sufficient to alter children’s processing of television messages.     

The fluency principle: Why foreign accent strength negatively biases language attitudes

Two experiments tested the prediction that heavy foreign-accented speakers are evaluated more negatively than mild foreign-accented speakers because the former are perceived as more prototypical (i.e., representative) of their respective group and their speech disrupts listeners’ processing fluency (i.e., is more difficult to process). Participants listened to a mild or heavy Punjabi- (Study 1) or Mandarin-accented (Study 2) speaker. Compared to the mild-accented speaker, the heavy-accented speaker in both studies was attributed less status (but not solidarity), was perceived as more prototypical of their respective group, disrupted listeners’ processing fluency, and elicited a more negative affective reaction. The negative effects of accent strength on status were mediated by processing fluency and sequentially by processing fluency and affect, but not by prototypicality. Theoretical, methodological, and practical implications are discussed.
