Power of Paradox: Grassroots Organizations’ Legitimacy Strategies Over Time
2021
Fringe stakeholders with limited resources, such as grassroots organizations (GROs), are often ignored in business and society literature. We develop a conceptual framework and a set of propositions detailing how GROs strategically gain legitimacy and influence over time. We argue that GROs encounter specific paradoxes over the emergence, development, and resolution of an issue, and they address these paradoxes using cognitive, moral, and pragmatic legitimacy strategies. While cognitive and moral strategies tend to be used consistently, the flexible and paradoxical use of pragmatic strategies has important consequences, both for GROs’ legitimacy and for their potential influence over powerf…
P-Value, Confidence Intervals, and Statistical Inference: A New Dataset of Misinterpretation
2017
Statistical inference is essential for science since the twentieth century (Salsburg, 2001). Since it's introduction into science, the null hypothesis significance testing (NHST), in which the P-value serves as the index of “statistically significant,” is the most widely used statistical method in psychology (Sterling et al., 1995; Cumming et al., 2007), as well as other fields (Wasserstein and Lazar, 2016). However, surveys consistently showed that researchers in psychology may not able to interpret P-value and related statistical procedures correctly (Oakes, 1986; Haller and Krauss, 2002; Hoekstra et al., 2014; Badenes-Ribera et al., 2016). Even worse, these misinterpretations of P-value …
Contextual perceived group threat and radical right-wing populist party preferences: Evidence from Switzerland
2016
Existing studies suggest that perceived group threat is an important influence on radical right-wing populist party preferences. However, most have focused on perceived group threat at the individual level, overlooking the ideological climate. I examine how an ideological climate of group threat perception as a contextual factor can shape individual preferences for radical right-wing populist party preferences. I argue that above and beyond personal perceived group threat, the prevalence of local perceived group threat exerts a normative influence on personal preferences. Using voting preferences for the Swiss People’s Party, I employ multilevel structural equation modeling to examine the …
Benefit Incidence Analysis in Education
2007
07103; The standard benefit incidence algebra generally produces biased estimates of the distribution of public spending on education when students from poor and rich families are enrolled in schools that receive different levels of public spending per student. Except in very rare instances, removing these biases entails combining several sources of information in order to evaluate how unit spending varies across different population groups. Although such disaggregation is generally difficult to obtain, we show one way to overcome the data constraints that hinder a precise calculation of the incidence of public spending on education. The empirical example discussed in this article indicates…
Contextuality in canonical systems of random variables
2017
Random variables representing measurements, broadly understood to include any responses to any inputs, form a system in which each of them is uniquely identified by its content (that which it measures) and its context (the conditions under which it is recorded). Two random variables are jointly distributed if and only if they share a context. In a canonical representation of a system, all random variables are binary, and every content-sharing pair of random variables has a unique maximal coupling (the joint distribution imposed on them so that they coincide with maximal possible probability). The system is contextual if these maximal couplings are incompatible with the joint distributions o…
QR kodu kā tirdzniecības instrumenta atbilstība uzņēmumiem
2021
Tā kā tehnoloģija ir pārņēmusi mārketinga pasauli, visefektīvākais mārketinga veids ir mobilais mārketings, un, mainoties tendencēm, daudzi mārketinga rīki ir praktizējuši, lai sniegtu produktīvu reklāmu. QR kodi pēdējos gados ir kļuvuši par jauno mārketinga tendenci, taču problēma ir tā, vai šie QR kodi patiešām ir produktīvi viņu centienos. Šī pētījuma mērķis ir analizēt, vai uzņēmumi, kas izmanto QR kodus kā savu mārketinga rīku, var sasniegt savus mērķus vai neietekmē mārketinga shēmas, kā arī noskaidrot, vai cilvēki zina QR kodus un vai tie tos ietekmē / piesaista. Pētījuma rezultāti acīmredzami atrisina pētījuma problēmu, uzņēmumi, kas izmanto QR kodus kā mārketinga rīku, sasniedz sav…
About complexity of the 2.16-eV absorption band in MgO crystals irradiated with swift Xe ions
2020
Abstract The precise study of the accumulation and subsequent thermal annealing of the defects responsible for the complex absorption band around 2.16 eV, being under discussion in the literature for a long time, has been performed in highly pure MgO single crystals exposed to 0.23-GeV 132Xe ions with a fluence of Φ = 5 × 1011 − 3.3 × 1014 ions/cm2. Three Gaussian components with the maxima at 2.16, 2.02 and 2.40 eV have been considered as a measure of so-called D1, D2 and D3 defects. Similar to the F and F+ centers, the concentration of these defects increases at high fluences without saturation marks, thus confirming their radiation-induced nature (involvement of novel Frenkel defects). T…
Color centers and structural damage in LiF induced by 150 MeV Kr ions
2012
Color centers and evolution of structure defects were investigated in LiF crystals irradiated at room temperature with 150 MeV 84Kr ions with a beam current of 10nA/cm2 in the fluence range 1011 - 1014 ions/cm2 at the cyclotron accelerator DC-60 (Astana, Kazakhstan). At the fluence of 1011 ions/cm2, SEM imaging revealed mainly formation of etchable ion tracks. Above this fluence, severe structural modifications in the irradiated layer were observed which include the ion-induced formation of dislocations and grains with nano-scale dimensions. The role of fluence in the concentration of electronic color centers and structural modifications is discussed.
Evaluation of the relative thermoluminescence efficiency of LiF:Mg,Ti and LiF:Mg,Cu,P TL detectors to low-energy heavy ions
2013
Abstract The most popular types of LiF-based thermoluminescent (TL) detectors, LiF:Mg,Ti (MTS-N) and LiF:Mg,Cu,P (MCP-N), have been investigated, with respect to their dose (fluence) response and relative TL efficiency to different ion species. The detectors were irradiated using the nitrogen, iron, krypton and xenon ion beams, at energies ranging from 5.0 to 9.3 MeV/n. Supra- and sublinear response was found, for the MTS-N and MCP-N, respectively, similarly as observed for γ-rays. However, the level of nonlinearity of response of studied detectors is strongly reduced by increasing values of the ion ionization density (no supralinearity for Xe ions, for MTS-N, within calculated uncertaintie…
Contextuality Analysis of the Double Slit Experiment (With a Glimpse Into Three Slits)
2018
The Contextuality-by-Default theory is illustrated on contextuality analysis of the idealized double-slit experiment. The experiment is described by a system of contextually labeled binary random variables each of which answers the question: has the particle hit the detector, having passed through a given slit (left or right) in a given state (open or closed)? This system of random variables is a cyclic system of rank 4, formally the same as the system describing the EPR/Bell paradigm with signaling. Unlike the latter, however, the system describing the double-slit experiment is always noncontextual, i.e., the context-dependence in it is entirely explainable in terms of direct influences of…
