Priming Effects on Commitment to Help and on Real Helping Behavior
2014
Years of research on bystander apathy have demonstrated that the physical presence of others can reduce the tendency to help individuals needing assistance. Recent research on the implicit bystander effect has suggested that simply imagining the presence of others can lead to less helping behavior on a subsequent unrelated task. The present study was designed to contribute to previous findings on the implicit bystander effect by demonstrating these effects on commitment to help and on real helping behavior, rather than simply on intentions to help. Studies 1a and 1b demonstrate that merely priming participants with the construct of being in a group at Time 1 created significantly less commi…
Processes of Personality Development in Adulthood: The TESSERA Framework.
2016
The current article presents a theoretical framework of the short- and long-term processes underlying personality development throughout adulthood. The newly developed TESSERA framework posits that long-term personality development occurs due to repeated short-term, situational processes. These short-term processes can be generalized as recursive sequence of Triggering situations, Expectancy, States/State expressions, and Reactions (TESSERA). Reflective and associative processes on TESSERA sequences can lead to personality development (i.e., continuity and lasting changes in explicit and implicit personality characteristics and behavioral patterns). We illustrate how the TESSERA framework f…
Reliability of Implicit Self–Esteem Measures Revisited
2011
This study investigated the internal consistencies and temporal stabilities of different implicit self–esteem measures. Participants ( N = 101) responded twice—with a time lag of 4 weeks—to five different tasks: the Implicit Association Test (IAT), the Brief Implicit Association Test (BIAT), the Affective Priming Task (APT), the Identification–Extrinsic Affective Simon Task (ID–EAST) and the Name–Letter Task (NLT). As expected, the highest reliability coefficients were obtained for the self–esteem IAT. Importantly, the internal consistencies and the temporal stabilities of the APT, the ID–EAST, and the NLT were substantially improved by using material, structural, and analytic innovations.…
Personality Expression and Impression Formation in Online Social Networks: An Integrative Approach to Understanding the Processes of Accuracy, Impres…
2014
In this paper, we investigate personality expression and impression formation processes in online social networks (OSNs). We explore whether, when and why people accurately judge others’ personalities (accuracy), successfully manage the impressions that others form of them (impression management) and accurately infer others’ impressions of them (meta–accuracy) at zero acquaintance. On the basis of targets’ OSN profiles (N = 103), overall perceiver impressions were collected and compared with targets’ self–view, desired impression and meta–perception. In addition, independent groups of thin–slice perceivers based their personality impressions solely on one of four kinds of information withi…
Changes in achievement values from primary to lower secondary school among students with and without externalizing problems
2017
This study examined the effect of students' externalizing problems on changes in values that they attach to math across the transition from primary to lower secondary school. Data pertaining to externalizing problems and to intrinsic, attainment, and utility values in math were gathered using the self-ratings of students in Grades 6 and 7. The analysis involved a comparison between students who reported persistent high externalizing problems before and after the transition (n = 63; 59% boys) and those who had low or non-existent externalizing problems before and after the transition (n = 1352; 50% boys). The results of a mixed-design analysis of covariance (ANCOVA) showed uniformly that stu…
Designed for unanticipated use
2003
Common artefacts have been identified as fundamental characteristics for framing activities in workplaces. Mike Robinson's article 'Design for unanticipated use...' conceptualised and defined the dimensions of common artefacts as consisting of predictability, peripheral awareness, implicit communication, double level language and overview. These dimensions have often been used in explaining unexpected uses of different applications and systems. In this paper, experiences from common artefacts as CSCW application design principles, indicating that unanticipated uses are expected and further supported, are discussed. Two distinct cases, a physical room and a software application, are presente…
NMR relaxation and solvation equilibrium in the ternary system CCl4-polymethylmethacrylate-benzene
2007
In the ternary system CCl4-PMMA-benzene, benzene is preferentially adsorbed in the solvation shell of the polymer. One solvation equilibrium constant allows a satisfactory description of the preferential solvation for a large range of solvent compositions. The nuclear magnetic relaxation time T1 of benzene protons was measured for different values of the polymer concentration. The measurements are compared with analogous measurements in the system C6D6-PMMA-C6H6 where no preferential solvation is to be expected. For the system CCl4-PMMA-benzene the resulting dimensionless solvation equilibrium constant is K = c32c10/c12c30 = 2.5 ± 0.5 where c10 is the CCl4 concentration in the “free” solven…
Review of Agent-Based Models of Social Conflict and Civil Violence
2017
This chapter contains a review of the state of the art on agent-based models for simulation of large-scale social conflict and violence. It is structured in four parts. The first contains a summary of general definitions and concepts. The second contains the presentation and discussion of Epstein’s agent-based model, which is a landmark model of civil and ethnic violence due to its simplicity, soundness, and explanatory power. The third part contains a review of extensions of Epstein’s model that have been proposed by several authors. The chapter ends with some remarks on the limitations of existing ABM and on possibilities for their improvement.
Shaded-Mask Filtering for Extended Depth-of-Field Microscopy
2013
This paper proposes a new spatial filtering approach for increasing the depth-of-field (DOF) of imaging systems, which is very useful for obtaining sharp images for a wide range of axial positions of the object. Many different techniques have been reported to increase the depth of field. However the main advantage in our method is its simplicity, since we propose the use of purely absorbing beam-shaping elements, which allows a high focal depth with a minimum modification of the optical architecture. In the filter design, we have used the analogy between the axial behavior of a system with spherical aberration and the transverse impulse response of a 1D defocused system. This allowed us the…
Updating input–output matrices: assessing alternatives through simulation
2009
A problem that frequently arises in economics, demography, statistics, transportation planning and stochastic modelling is how to adjust the entries of a matrix to fulfil row and column aggregation constraints. Biproportional methods in general and the so-called RAS algorithm in particular, have been used for decades to find solutions to this type of problem. Although alternatives exist, the RAS algorithm and its extensions are still the most popular. Apart from some interesting empirical and theoretical properties, tradition, simplicity and very low computational costs are among the reasons behind the great success of RAS. Nowadays computer hardware and software have made alternative proce…
