Perceiver Effects

Person judgments reflect perceiver effects: differences in how perceivers judge the average person. The factorial structure of such effects is still discussed. We present a large-scale, preregistered replication study using over 1 million person judgments (different groups of 200 perceivers judged 200 targets in one of 20 situations, using 30 personality items). Results unanimously favored a model comprising three systematic components: acquiescence (endorsing all items more than other perceivers), positivity (endorsing positive over negative items), and trait specificity (endorsing items reflecting a specific trait more). The latter two factors each accounted for approximately a quarter of the variance in perceiver effects, and acquiescence accounted for less than 10%. Positivity was more influential for evaluative items and was strongly associated with how likable perceivers found their targets to be ( r = .55). With considerable statistical power and generalizability, our findings significantly improve the knowledge base regarding the structure of perceiver effects.

AbstractWe investigated the influence of upstream terrain on the formation of a cold frontal snowband in Northeast China. We conducted numerical sensitivity experiments that gradually removed the upstream terrain and compared the results with a control experiment. Our results indicate a clear negative effect of upstream terrain on the formation of snowbands, especially over large-scale terrain. By thoroughly examining the ingredients necessary for snowfall (instability, lifting and moisture), we found that the release of mid-level conditional instability, followed by the release of low-level or near surface instabilities (inertial instability, conditional instability or conditional symmetrical instability), contributed to formation of the snowband in both experiments. The lifting required for the release of these instabilities was mainly a result of frontogenetic forcing and upper gravity waves. However, the snowband in the control experiment developed later and was weaker than that in the experiment without upstream terrain. Two factors contributed to this negative topographic effect: (1) the mountain gravity waves over the upstream terrain, which perturbed the frontogenetic circulation by rapidly changing the vertical motion and therefore did not favor the release of instabilities in the absence of persistent ascending motion; and (2) the decrease in the supply of moisture as a result of blocking of the upstream terrain, which changed both the moisture and instability structures leeward of the mountains. A conceptual model is presented that shows the effects of the instabilities and lifting on the development of cold frontal snowbands in downstream mountains.

PurposeThe internet has made it possible to diffuse totally digitized products on a very large scale. The newspaper business is one of the sectors that has been most affected by this technological revolution. Given such products’ uneven commercial success, an analysis of the literature suggests that these mixed results could be explained by the digitized nature of the product combined with a price judged too high. Both these elements reduce the perceived global value of the digital support compared with the print version on paper. To test this proposition, the authors have constructed an experimental design, manipulating the format (digital newspaper vs. print newspaper) and the price (high vs low). The results show that newspaper digitization significantly reduces perceived global value for the consumer compared with the print format. The authors also show that the perceived intangibility of the product exerts a more complex effect on perceived global value: this effect depends on both the nature of the intangibility (mental vs physical) and the cost and benefit analysis.Design/methodology/approachAn experimental study was conducted with two factors: digitalization (print vs digital format) and price (low vs high). The authors carried out a mixed-factor variance analysis and follow Preacher and Hayes procedure to test the hypothesis. A sample of 387 undergraduate students was interviewed in laboratory.FindingsThe results show that newspaper digitization significantly reduces (i.e. destroys) perceived global value for the consumer (i.e. it destroys value), compared to the print format. The reuslts also show that the perceived intangibility of the product exerts a more complex effect on perceived global value: this effect depends at the same time on the nature of the intangibility (mental vs physical) and the account taken of costs and benefits.Originality/valueOne major result is the fact that digitizing newspaper strongly destroys its perceived global value for the consumer, compared to the physical alternative. To explain this phenomenon, the product’s perceived intangibility had been considered, as well as how this is related to the perceived costs and benefits. It appears that it has an overall direct negative effect on perceived value; therefore, the more a newspaper format is perceived as physically intangible, the more its perceived global value decreases. Results shows that this loss of value can be counteracted in two different ways, through the indirect effects of costs and benefits.

Abstract. The present study analyses the psychometric properties proposed by Blanco, Blanco, Viciana, and Zueck (2015) for the Physical Self-Concept Scale (CAF). The total sample consisted of 1,500 Mexican university students, with a mean age of 20.69 years (± SD = 2.33). Confirmatory factorial analyses showed that a two-factor structure is viable and adequate for both studied groups (men and women). The structure of two factors (motor competence and physical attractiveness), according to statistical and substantive criteria, has shown adequate indicators of reliability and validity adjustment. In addition, the factorial structure, factor loads and intercepts are considered invariant in the two groups studied. However, differences between the two groups for the factor means were found. Further research should replicate these findings in larger samples.Resumen.

La muestra total fue de 1500 universitarios mexicanos, con una edad media de 20.69 años (± DE=2.33). Los análisis factoriales confirmatorios mostraron que una estructura de dos factores es viable y adecuada para ambos grupos (hombres y mujeres). La estructura de dos factores (competencia motora y atractivo físico), atendiendo a criterios estadísticos y sustantivos, ha mostrado adecuados indicadores de ajuste de fiabilidad y validez. Además, la estructura factorial, las cargas factoriales y los interceptos se consideran invariantes en las dos poblaciones estudiadas; sin embargo, existen diferencias entre las poblaciones para las medias de los factores. Futuras investigaciones deberían replicar estos hallazgos en muestras más amplias.

There is a steady trend in the wide range of literature on the study of institutions: the definition of theoretical judgments often does not coincide and is not combined with the definition of general connections and patterns, which leads to ignoring the principle of systematic analysis of socio-economic processes. Indirectly, this means the priority of the random (individual) over the whole and general. Meanwhile, the concept of an institution correlates with the specific content of a phenomenon or process and is supplemented by a generalized and systematic approach. The study of such an urgent problem of the market economy as institutional choice through non-profit organizations requires the extension of the analysis not only to governmental but also to non-governmental structures, which are an element of the whole. In this regard, the article provides a historical overview of the development of nonprofit organizations and charitable activities as a large-scale social phenomenon, which made it possible to draw attention to the possibility of using the experience of past years for the purposeful organization of non-state institutions of charity, including by improving social partnerships. Analysis of the current state of non-profit organizations in Ukraine, despite the growth in their number, shows a decrease in the volume of charitable activities. In recent years, the country has taken certain steps to improve charity. However, this is not enough. The institutional environment for philanthropy needs to be improved. The solution to this problem is possible with the active influence of the state on the management of non-commercial activities. Improving the tools of functioning, financing, as well as increasing attention to the development of statistics in this area of activity is considered relevant. In this regard, the purpose of the article is to identify pressing issues and ways to improve charitable organizations. The solution to this problem is possible with the active influence of the state on the management of non-profit activities. The development of the institutional framework of the nonprofit sector of the economy means the improvement of financial reporting, greater openness of charitable organizations, streamlining of their legal relations, liberalized taxation and strengthened control over the activities of non-profit organizations. The article pays special attention to the problem of accumulation and distribution of charitable funds. The potential of charitable organizations can be expanded by shifting the focus of their regulation away from predominantly corporate to regional administration, which increases the importance of the institution of partnership in the development of charity. The article uses historical and logical methods, which allowed to study the formation and development of non-profit organizations in the evolutionary aspect.

Joint analysis of data from multiple studies in collaborative efforts strengthens scientific evidence, with the gold standard approach being the pooling of individual participant data (IPD). However, sharing IPD often has legal, ethical, and logistic constraints for sensitive or high-dimensional data, such as in clinical trials, observational studies, and large-scale omics studies. Therefore, meta-analysis of study-level effect estimates is routinely done, but this compromises on statistical power, accuracy, and flexibility. Here we propose a novel meta-analytical approach, named partial derivatives meta-analysis, that is mathematically equivalent to using IPD, yet only requires the sharing of aggregate data. It not only yields identical results as pooled IPD analyses, but also allows post-hoc adjustments for covariates and stratification without the need for site-specific re-analysis. Thus, in case that IPD cannot be shared, partial derivatives meta-analysis still produces gold standard results, which can be used to better inform guidelines and policies on clinical practice.

Many workflows and tools that aim to increase the reproducibility and replicability of research findings have been suggested. In this review, we discuss the opportunities that these efforts offer for the field of developmental cognitive neuroscience, in particular developmental neuroimaging. We focus on issues broadly related to statistical power and to flexibility and transparency in data analyses. Critical considerations relating to statistical power include challenges in recruitment and testing of young populations, how to increase the value of studies with small samples, and the opportunities and challenges related to working with large-scale datasets. Developmental studies involve challenges such as choices about age groupings, lifespan modelling, analyses of longitudinal changes, and data that can be processed and analyzed in a multitude of ways. Flexibility in data acquisition, analyses and description may thereby greatly impact results. We discuss methods for improving transparency in developmental neuroimaging, and how preregistration can improve methodological rigor. While outlining challenges and issues that may arise before, during, and after data collection, solutions and resources are highlighted aiding to overcome some of these. Since the number of useful tools and techniques is ever-growing, we highlight the fact that many practices can be implemented stepwise.

Humans have been using language for thousands of years, but psychologists seldom consider what natural language can tell us about the mind. Here we propose that language offers a unique window into human cognition. After briefly summarizing the legacy of language analyses in psychological science, we show how methodological advances have made these analyses more feasible and insightful than ever before. In particular, we describe how two forms of language analysis—comparative linguistics and natural language processing—are already contributing to how we understand emotion, creativity, and religion, and overcoming methodological obstacles related to statistical power and culturally diverse samples. We summarize resources for learning both of these methods, and highlight the best way to combine language analysis techniques with behavioral paradigms. Applying language analysis to large-scale and cross-cultural datasets promises to provide major breakthroughs in psychological science.

Technogenic Noise

Object and purpose of research. The study addresses the technogenic underwater noise issues with a view to environmental and competitive challenges, as well as the Navy interests. Materials and methods. The issues studied in this investigation are relatively new for the Russian shipbuilding, shipping and marine activities, and the first step to systematic studies should be formulation of a technogenic noise problem as a physical phenomenon, which have to be considered in the state marine and transportation policy. The paper uses results of design studies performed in Krylov State research Centre, as well as information from mass media. The main sources of the technogenic underwater noise are coastal industries and port infrastructure, marine oil & gas structures, transport and ice-breaking vessels. Main results. It is concluded that a special-purpose integrated target program should be formulated and performed, whose result would be systematization of research and design projects aimed at the analysis, regulation and standardization of technogenic underwater noise parameters of various marine technologies. Conclusion. Technogenic underwater noise is directly related to the safety of marine ecosystems. In addition, it is a factor of commercial and large-scale economic competition in the international community. In future the technogenic underwater noise of marine facilities may become an instrument of competition for the opportunity and right to exploit Russian oil & gas deposits, as well as to use Russian Arctic routes. Against the backdrop of these two factors, the Navy interests are obviously to raise the efficiency of fixed and mobile sonar systems in the environment of high technogenic noise produced by civil marine activities.

Pink Salmon Oncorhynchus Gorbuscha

Since 1950, stocks of British Columbia pink salmon (Oncorhynchus gorbuscha) have shown up to a 34% decrease in mean adult body weight, causing significant reduction in economic value of commercial harvests. Previous research suggests that this trend is due to size-selective harvesting of large fish, but changes in oceanographic conditions are a plausible alternative. Corrective action by management agencies requires that the true causal mechanism be identified. We therefore examined several possible designs for a large-scale fishing experiment devised to test the size-selective fishing hypothesis. These designs would generate accurate and precise field estimates of the heritability (h2) of growth rate, which is important because it, in combination with the selection differential (D) caused by fishing, determines how rapidly body size changes. Monte Carlo simulations showed that block designs with three to six spatial replicates and relatively short durations generated high statistical power. For example, for h2 = 0.22, D = 0.25 kg, and four spatial replicates, an 8-yr experiment resulted in power = 0.87, which gave a SE < 0.10 for h2 = 0.22. We conclude that some experimental designs have good potential to test the possible effects of size-selective fishing on mean adult size of British Columbia pink salmon.
