The Impact

The factorial survey is an experimental design in which the researcher constructs varying descriptions of situations or individual persons (vignettes), which will be judged by respondents with regard to a particular aspect. Some researchers present vignettes in text format as short stories, others present the central information of vignettes in a tabular format. To date, only a few sentences have been published, by Auspurg and Hinz, on the impact of the presentation format (text vs. table) on the answer behavior of students. Empirically, no differences were found between either format. Based on an Internet experiment conducted with a quota sample, we find evidence that ordinary tabular formats outperform text vignettes in terms of total vignette nonresponse but not when it comes to processing time. The former result especially applies in the case of less well-educated people. We further find that tabular format does not perform worse than text format regarding response inconsistency.

The impact of emotional communication on perceived sincerity and reputation of organizations in crisis The impact of emotional communication on perceived sincerity and reputation of organizations in crisis This paper examines the impact of emotional communication of an organizational spokesperson in times of crisis on consumers’ perceptions of the spokesperson (i.e. sincerity) and the organization (i.e. reputation) by two experimental studies. The results of study one using a 2 (crisis timing strategy: thunder vs. stealing thunder) × 2 (rational vs. sad message) between-subjects experimental design illustrates that emotional crisis communication leads to less reputational damage than rational crisis communication (N = 168), but only if the organization self-discloses the incrementing information. In study two, the discrete emotions were manipulated in a self-disclosing setting to be sadness or anger (N = 60). The results of study two show that a company is perceived to take more responsibility for the crisis when the spokesperson expresses sadness instead of anger. The sincerity of the spokesperson/organization mediates these effects. Both studies stress the importance of emotional communication by spokespersons for organizations in crisis.

PurposeA principle prerequisite for designing and constructing an underground structure is to estimate the subsurface's properties and obtain a realistic picture of stratigraphy. Obtaining direct measure of these values in any location of the built environment is not affordable. Therefore, any evaluation is afflicted with uncertainty, and we need to combine all available measurements, observations and previous knowledge to achieve an informed estimate and quantify the involved uncertainties. This study aims to enhance the geotechnical surveys based on a spatial estimation of subsoil to customised data structures and integrating the ground models into digital design environments.Design/methodology/approachThe present study's objective is to enhance the geotechnical surveys based on a spatial estimation of subsoil to customised data structures and integrating the ground models into digital design environments. A ground model consisting of voxels is developed via Revit-Dynamo to represent spatial uncertainties employing the kriging interpolation method. The local arrangement of new surveys are evaluated to be optimised.FindingsThe visualisation model's computational performance is modified by using an octree structure. The results show that it adapts the structure to be modelled more efficiently. The proposed concept can identify the geological models' risky locations for further geological investigations and reveal an optimised experimental design. The modifications criteria are defined in global and local considerations.Originality/valueIt provides a transparent and repeatable approach to construct a spatial ground model for subsequent experimental or numerical analysis. In the first attempt, the ground model was discretised by a grid of voxels. In general, the required computing time primarily depends on the size of the voxels. This issue is addressed by implementing octree voxels to reduce the computational efforts. This applies especially to the cases that a higher resolution is required. The investigations using a synthetic soil model showed that the developed methodology fulfilled the kriging method's requirements. The effects of variogram parameters, such as the range and the covariance function, were investigated based on some parameter studies. Moreover, a synthetic model is used to demonstrate the optimal experimental design concept. Through the implementation, alternative locations for new boreholes are generated, and their uncertainties are quantified. The impact of the new borehole on the uncertainty measures are quantified based on local and global approaches. For further research to identify the geological models' risky spots, the development of this approach with additional criteria regarding the search neighbourhood and consideration of barriers and trends in real cases (by employing different interpolation methodologies) should be considered.

This paper reports on an in-depth examination of the impact of the backing filesystems to Docker performance in the context of Linux container-based virtualization. The experimental design was a 3x3x4 arrangement, i.e., we considered three different numbers of Docker containers, three filesystems (Ext4, XFS and Btrfs), and four application workloads related to Web server I/O activity, e-mail server I/O activity, file server I/O activity and random file access I/O activity, respectively. The experimental results indicate that Ext4 is the most optimal filesystem, among the considered filesystems, for the considered experimental settings. In addition, the XFS filesystem is not suitable for workloads that are dominated by synchronous random write components (e.g., characteristical for mail workload), while the Btrfs filesystem is not suitable for workloads dominated by random write and sequential write components (e.g., file server workload).

The Impact

We investigated how evaluation standards employed in performance tests affect the impact of performance goals (here: focused on appearance) on academic cheating. Thereby, we assumed that appearance goals would only lead to increased cheating if students’ performance was presumably evaluated based on results rather than on strategies applied to solve the questions. 169 university students (68.6% female) participated in an experimental design with 2 (induced appearance goals versus no goal induction) x 2 (process-based versus result-based evaluation standards) between-subject conditions. We assessed cheating using a confederate student observing participants’ behaviors and by measuring whether participants reported that they solved unsolvable questions. Confirming our hypotheses, we found that students were only more likely to cheat when appearance goals were induced and the evaluation standard focused on the results. This new knowledge helps to explain mixed findings regarding how performance goals affect cheating and provides opportunities to reduce cheating in high-stakes testing situations.

The way that diversity, equity, and inclusion impact scientific careers varies for everyone, but it is evident that institutions providing an environment where being different or having differences creates a sense of being welcomed, supported, and valued are beneficial to the scientific community at large. In this commentary, three short stories from Texas-based microbiologists are used to depict (i) the importance of bringing the guiding principles of diversity, equity, and inclusion within their professional roles, (ii) the need to apply and translate those principles to support and enable successful scientific careers among peers and trainees, and (iii) the impact of effective science communication to increase the understanding of microbial environments among the community at large.

<em>The goverment made changes to the Indonesian education curriculum of the education unit level curriculum into the curriculum of 2013. Changes in the curriculum in 2013 lies in the preparation of the RPP (Lesson Plan) and the ability of literacy. The emphasis on the preparation of the RPP has been resolved with the holding of training, but to literacy still unwell. One way to improve the literacy skills is through the reading of short stories. The reading of the short story aims to help improve reading skills and knowledge of sentence patterns, so it can be an idea to create an article. The focus on this study include: (1) The concept of reading a short story; (2) The impact of short story readings. These studies include: (1) The reading of short stories is an activity habituation to read a fictional narrative prose text .; (2) The impact resulting from the reading of short stories such as enhancing the knowledge, encourage the growth likes to read, and to foster the ability to write.</em>
