Prosocial Behavior and Posttraumatic Growth After Trauma

The purpose of this study was to examine prosocial behaviors of individuals who have or have not experienced individual traumas, and to assess whether experiencing multiple types of trauma will be related to prosocial behavior and posttraumatic growth. There were 118 undergraduate students who responded to an online survey comprised of three established measures. Participants indicated the nature of traumatic events through a checklist, with prosocial behavior and posttraumatic growth assessed through self-report questionnaires. There was no difference between those who experienced trauma and those who had not experienced trauma in their tendencies toward prosocial behavior. However, individuals who had experienced at least one traumatic event and who reported strong tendencies toward prosocial behavior did report higher levels of posttraumatic growth than those who reported weaker tendencies toward prosocial behavior. Although experiencing one or more than one type of traumatic event had no significant relationship with prosocial behavior, participants who experienced one type of traumatic event reported lower levels of posttraumatic growth than those who experienced more than one type of trauma. The potential for prosocial behavior to be linked more with posttraumatic growth than to traumatic experiences is discussed

Study of the charge profile of thermally poled electrets

The charge profile of thermally poled electrets has been studied using two different methods, laser induced pressure pulse (LIPP) and pulsed electroacoustic (PEA), to gain insight into the mechanisms that are activated and assess which is the most appropriate method to study the charge profile. Disc--shaped PET samples have been conventionally poled to activate both the alpha and the rho relaxation and, right after, partially discharged up to a temperature Tpd. In this way, samples with a different combination of dipolar and space charge polarization have been obtained. Both LIPP and PEA reveal asymmetric profiles for Tpd below the glass transition temperature, that progressively become antisymmetric for higher temperatures. The shape and evolution of the charge profiles can be explained assuming injection of negative carriers from the anode that enhances the trapping of positive carriers near this electrode. It can be observed that PEA is able to detect a wider variety of polarization mechanisms in the system while LIPP gives a simpler picture of the charge profile.Comment: 19 pages, 11 figure

Legal Accountability and Nonprofit Governance: An Exploratory Quantitative Study of Board Member and Executive Knowledge of Fiduciary Duties

United States nonprofits are governed by boards of directors who have legal responsibilities based on the fiduciary duties of care, loyalty, and obedience. Boards, along with the chief executive, are held responsible to fulfill these standards which are designed to hold nonprofits legally accountable to carry out their tax exempt purpose by using organizational resources for the intended purpose, avoid conflict of interest, and ensure compliance. However, despite this weighty responsibility and the voluntary nature of nonprofits, no standardized process exists to educate nonprofit leaders about their legal responsibilities. While governance is a key area of nonprofit research, there is limited empirical evidence about how nonprofit leaders satisfy legal accountability demands. Using quantitative methods, this three paper dissertation establishes baseline data about nonprofit leader fiduciary knowledge, source of knowledge, and application of knowledge in their governance activities. A survey tool developed for this study yielded 186 responses from San Diego County nonprofit leaders. Using role and board service as the primary demographics, the results show that most nonprofit leaders believe they have enough knowledge of the fiduciary duties and frequently use their knowledge in the performance of their governance duties. However, when tested for actual knowledge, only 41% of board members and 70% of executives passed. When analyzed by board service, 56% of those who served on one to four boards in the past 15 years and 31% of those who have served on five or more boards passed. Further results show that nonprofit leaders were more likely to rely on informal sources of knowledge, such as conversations with their colleagues and other board members and less on more formalized sources, such as board orientations or a board manual, regardless of role or board service. Implications of this study point to the need for increased fiduciary duty knowledge amongst nonprofit leaders. Furthermore, this study can inform regulators, funders, and practitioners to develop standards and fund training to strengthen nonprofit accountability. As nonprofit leaders understand their fiduciary duties more fully, they are empowered to make decisions about organizational resources that uphold their legal responsibilities to carry out the mission

Lafayette, the Thinker

Between 1775 and 1834, the Marquis de Lafayette played a role in the ongoing development of both the American and French Revolutions. Most previous scholarship about Lafayette highlights his military activities as a major-general in the American Revolution and as General of the National Guard of Paris in the French Revolution. This paper examines Lafayette’s draft of the Declaration of the Rights of the Man and of the Citizen, a list of enslaved peoples that were chosen for Lafayette’s experimental plantation in French Guiana, Lafayette’s membership in the Society of the Friends of Blacks, and letters between Lafayette and America’s Founding Fathers to suggest that Lafayette was deeply concerned with questions of liberty and slavery. Overall, this paper demonstrates that the Marquis de Lafayette played a far larger role than as a military general, instead he acted as one the greatest thinkers of the Revolutionary Era

Rock Art and State Formation in Ancient Egypt

The process of state formation in Egypt has been variously modeled. Lapidary tableaux from the eastern and western deserts of Egypt have been dated stylistically to the later period of state formation, the Late Predynastic. This thesis provides an overview of select theories on state formation, with particular focus on ancient Egypt. Those theories are then used as a lens, through which three rock art tableaux might be better understood and dated. This thesis will examine specifically the chronological stages of state formation outlined by Anđelković. After dating two other rock art tableaux to the Late Predynastic Period, I assign them to one of Anđelković’s five hypothesized stages of Egyptian state formation. I then evaluate whether his description of the Egyptian state at that phase is congruent with the iconography and content within the scenes

In situ decolorization monitoring of textile dyes for an optimized UV-LED/TiO2 reactor

Heterogeneous photocatalysis, using photocatalysts in suspension to eliminate diverse contaminants, including textile wastewater, has several advantages. Nevertheless, current absorbance and decolorization measurements imply sample acquisition by extraction at a fixed rate with consequent photocatalyst removal. This study presents online monitoring for the decolorization of six azo dyes, Orange PX-2R (OP2), Remazol Black B133 (RB), Procion Crimson H-EXL (PC), Procion Navy H-EXL (PN), Procion Blue H-EXL (PB), and Procion Yellow H-EXL (PY), analyzing the spectrum measured in situ by using the light scattering provided by the photocatalyst in suspension. The results obtained have corroborated the feasibility of obtaining absorbance and decolorization measurements, avoiding disturbances in the process due to a decrease in the volume in the reactor.Peer ReviewedPostprint (published version
