Item context effects refer to the impact of features of a test on an examinee’s item responses. These effects cannot be explained by the abilities measured by the test. Investigations typically focus on only a single type of item context effects, such as item position effects, or mode effects, thereby ignoring the fact that different item context effects might operate simultaneously. In this study, two different types of context effects were modeled simultaneously drawing on data from an item calibration study (...) of a multidimensional computerized test (N = 1,632) assessing student competencies in mathematics, science, and reading. We present a generalized linear mixed model (GLMM) parameterization of the multidimensional Rasch model including item position effects (distinguishing between within-block position effects and block position effects), domain order effects, and the interactions between them. Results show that both types of context effects played a role, and that the moderating effect of domain orders was very strong. The findings have direct consequences for planning and applying mixed domain assessment designs. (shrink)

Cluster growth models are utilized for a wide range of scientific and engineering applications, including modeling epidemics and the dynamics of liquid propagation in porous media. Invasion percolation is a stochastic branching process in which a network of sites is getting occupied that leads to the formation of clusters. The occupation of sites is governed by their resistance distribution; the invasion annexes the sites with the least resistance. An iterative cluster growth model is considered for computing the expected size and (...) perimeter of the growing cluster. A necessary ingredient of the model is the description of the mean perimeter as the function of the cluster size. We propose such a relationship for the site square lattice. The proposed model exhibits the expected phase transition of percolation models, i.e., it diverges at the percolation threshold p c. We describe an application for the porosimetry percolation model. The calculations of the cluster growth model compare well with simulation results. (shrink)

The question concerning the meaning of life is important, but it immediately confronts the present authors with insurmountable obstacles from a philosophical standpoint, as it would require us to define not only what we hold to be life, but what we hold to be meaning in addition, requiring us to do both in a properly researched context. We unconditionally surrender to that challenge. Instead, we offer a vernacular, armchair approach to life’s origin and meaning, with some layman’s thoughts on the (...) meaning of origins as viewed from the biologist’s standpoint. One can observe that biologists generally approach the concept of biological meaning in the context of evolution. This is the basis for the broad resonance behind Dobzhansky’s appraisal that “Nothing in biology makes sense except in the light of evolution”. Biologists try to understand living things in the historical context of how they arose, without giving much thought to the definition of what life or living things are, which for a biologist is usually not an interesting question in the practical context of daily dealings with organisms. Do humans generally understand life’s meaning in the context of history? If we consider the problem of life’s origin, the question of what constitutes a living thing becomes somewhat more acute for the biologist, though not more answerable, because it is inescapable that there was a time when there were no organisms on Earth, followed by a time when there were, the latter time having persisted in continuity to the present. This raises the question of where, in that transition, chemicals on Earth became alive, requiring, in turn, a set of premises for how life arose in order to conceptualize the problem in relation to organisms we know today, including ourselves, which brings us to the point of this paper: In the same way that cultural narratives for origins always start with a setting, scientific narratives for origins also always start with a setting, a place on Earth or elsewhere where we can imagine what happened for the sake of structuring both the problem and the narrative for its solution. This raises the question of whether scientific origins settings convey meaning to humans in that they suggest to us from what kind of place and what kinds of chemicals we are descended, that is, to which inanimate things we are most closely related.

In this manuscript, we define and discuss a new type of logical puzzles. These puzzles are based on the simplest truth-teller and liar puzzles. Graphs are used to represent graphically the puzzles. these logical puzzles contain three types of people. Strong Truth-tellers who can say only true statements, Strong Liars who can make only false statements and Weak Crazy people who must make at least one self-contradicting statement if he/she says anything. Self-contradicting statements are related to the Liar paradox, such (...) that, there is no Truth-teller or a Liar could say “I am a Liar”. In any good puzzle there is a unique solution, while the puzzle is clear if only the people of the puzzle and their statements are given to solve the puzzle. It is well-known that there is no good and clear SS-puzzle. However, in this paper, we show that there are clear and good SSW-puzzles. Characteristics of the newly investigated type of people, the ‘Weak Crazy’ people, has also been studied. Some statistical results about the new type of puzzles and a comparison with other types of puzzles are also shown: the number of solvable and also the number of good puzzles is much larger than in the previously known SS-puzzles.

Major events of the cell cycle—DNA synthesis, mitosis and cell division—are regulated by a complex network of protein interactions that control the activities of cyclin‐dependent kinases. The network can be modeled by a set of nonlinear differential equations and its behavior predicted by numerical simulation. Computer simulations are necessary for detailed quantitative comparisons between theory and experiment, but they give little insight into the qualitative dynamics of the control system and how molecular interactions determine the fundamental physiological properties of cell (...) replication. To that end, bifurcation diagrams are a useful analytical tool, providing new views of the dynamical organization of the cell cycle, the role of checkpoints in assuring the integrity of the genome, and the abnormal regulation of cell cycle events in mutants. These claims are demonstrated by an analysis of cell cycle regulation in fission yeast. BioEssays 24:1095–1109, 2002. © 2002 Wiley‐Periodicals, Inc. (shrink)

How was violence justified in early Islam? What role did violent actions play in the formation and maintenance of the Muslim political order? How did Muslim thinkers view the origins and acceptability of violence? These questions are addressed by an international range of eminent authors through both general accounts of types of violence and detailed case studies of violent acts drawn from the early Islamic sources. Violence is understood, widely, to include jihad, state repressions and rebellions, and also more personally (...) directed violence against victims (women, animals, children, slaves) and criminals. By understanding the early development of Muslim thinking around violence, our comprehension of subsequent trends in Islamic thought, during the medieval period and up to the modern day, become clearer.

This article presents findings of a research carried out among pro-refugee individuals in social media in Hungary. During the so-called refugee crisis that emerged in the summer of 2015, anti-immigrant sentiments in the Hungarian public were fueled by a strong governmental campaign. This unusually strong propaganda campaign created a strong hegemonic discourse. Nevertheless, a pro-refugee counterpublic opposing the hegemonic discourse also emerged. The article discusses existing scholarly literature on the phenomenon and how it appears in and is shaped by the (...) digital sphere. The empirical findings focus on two characteristics of the pro-refugee counterpublic. First, we look at the political affiliations of this counterpublic. Second, we ask if the different digital affordances used by the counterpublic and their combinations indicate the formation of a community. The methodological ambition of the article is to present a digital data-driven approach, based on data provided by Facebook, which allows the individual profiling of each user. The connections and schemata of these profiles provide the analytical background of the present research. We aim to illustrate that such a digital approach has a number of advantages over traditional sociological methods, especially in the research of subaltern counterpublics. (shrink)

The recent ability to inactivate specific genes in mice has significantly accelerated our understanding of molecular, cellular, and even behavioral aspects of normal and disease processes. However, this ability has also demonstrated the extreme complexity of genetic determination in mammals, in particular, that genes in the same family or pathway can be functionally redundant and that a given gene often has multiple roles. Thus, inactivation of a gene often does not indicate its complete spectrum of functions. To circumvent this problem, (...) many new tools and novel applications of classic techniques have been developed to place spatial and temporal restrictions on the genomic alterations. These approaches include chimera and mosaic studies, organ transplantation, complementation assays, dominant negative mutants, conditional gene knockouts, and lineage-specific gene rescue. Not only has this opened up more sophisticated ways to make genomic alterations, but it has provided the opportunity to create animal models for sporadic human genetic diseases.

Reflecting the dangers of irresponsible science and technology, Mary Shelley’s Frankenstein quickly became a mythic story that still feels fresh and relevant in the twenty-first century. The unique framework of the Frankenstein myth has permeated the public discourse about science and knowledge, creating various misconceptions around and negative expectations for scientists and for scientific enterprises more generally. Using the Frankenstein myth as an imaginative tool, we interviewed twelve scientists to explore how this science narrative shapes their views and perceptions of (...) science. Our results yielded two main conclusions. First, the Frankenstein myth may help scientists identify popular concerns about their work and offer a framework for constructing a more positive narrative. Second, finding optimistic science narratives may allow scientists to build a better relationship with the public. We argue that by showing the ethical principles and social dimensions of their work, scientists could replace a negative Frankenstein narrative with a more optimistic one. (shrink)

After the consultative synod at Constantinople in 1923, the Romanian Orthodox Church agreed to adopt a revised version of the Julian calendar. This meant a break with tradition that brought about a series of crises on a spiritual and political level. Dissent movements, known as Old Calendarist, started to emerge in the villages of Moldavia and Bessarabia; led by defrocked monks, these groups posed a threat for the Romanian Orthodox Church and for the newly formed state and its modernising goals. (...) Accused of sympathising with the communist ideas, as well as of propagating them, the Old Calendarist leaders were labelled as dangerous Bolsheviks and aggressive measures were adopted by both state and church authorities in order to destroy the movements and disperse their members. Based on press articles of the time and archival documents, the present study analyses the development that the Old Calendarist movement underwent in Bessarabia, a region with a strong monastic tradition, as well as the discourse and politics of state authorities against this specific community.

The hippocampal formation is known for its importance in conscious, declarative memory. Here, we report neuroimaging evidence in humans for an additional role of the hippocampal formation in nonconscious memory. We maskedly presented combinations of faces and written professions such that subjects were not aware of them. Nevertheless, the masked presentations activated many of the brain regions that unmasked presentations of these stimuli did. To induce a nonconscious retrieval of the faces and face-associated occupational information, subjects were instructed to view (...) the previously masked faces and to guess the professional category of each person—academic, artist, and workman. Guessing the professional category of previously masked versus new faces activated the left and right hippocampal formation and right perirhinal cortex as well as bilateral fusiform areas and fronto-temporal areas known to mediate the retrieval of semantic information. These activations within the semantic processing system suggest that conceptual knowledge acquired during masking was nonconsciously retrieved. Our data provide clues to an analogous role of the hippocampus in conscious and nonconscious memory. (shrink)

Since its first publication in 1818, Mary Shelley’s Frankenstein; or, The Modern Prometheus has transcended genres and cultures to become a foundational myth about science and technology across a multitude of media forms and adaptations. Following in the footsteps of the brilliant yet troubled Victor Frankenstein, professionals and practitioners have been debating the scientific ethics of creating life for decades, never before have powerful tools for doing so been so widely available. This paper investigates how engaging with the Frankenstein myth (...) may help scientists gain a more accurate understanding of their own beliefs and opinions about the social and ethical aspects of their profession and their work. The paper presents findings from phenomenological interviews with twelve scientists working on biotechnology, robotics, or artificial intelligence projects. The results suggest that the Frankenstein myth, and the figure of Victor Frankenstein in particular, establishes norms for scientists about what is considered unethical and dangerous in scientific work. The Frankenstein myth both serves as a social and ethical reference for scientists and a mediator between scientists and the society. Grappling with the cultural ubiquity of the Frankenstein myth prepares scientists to face their ethical dilemmas and create a more transparent research agenda. Meanwhile, by focusing on the differences between real scientists and the imaginary figure of Victor Frankenstein, scientists may avoid being labeled as dangerous individuals, and could better conceptualize the potential societal and ethical perceptions and implications of their research.

As one of the best known science narratives about the consequences of creating life, Mary Shelley’s Frankenstein; or, The Modern Prometheus is an enduring tale that people know and understand with an almost instinctive familiarity. It has become a myth reflecting people’s ambivalent feelings about emerging science: they are curious about science, but they are also afraid of what science can do to them. In this essay, we argue that the Frankenstein myth has evolved into a stigma attached to scientists (...) that focalizes the public’s as well as the scientific community’s negative reactions towards certain sciences and scientific practices. This stigma produces ambivalent reactions towards scientific artifacts and it leads to negative connotations because it implies that some sciences are dangerous and harmful. We argue that understanding the Frankenstein stigma can empower scientists by helping them revisit their own biases as well as responding effectively to people’s expectations for, and attitudes towards, scientists and scientific artifacts. Debunking the Frankenstein stigma could also allow scientists to reshape their professional identities so they can better show the public what ethical and moral values guide their research enterprises.
