description: Fluorochrome tagging is useful in growth, reproductive, and behavior studies. One commonly used fluorochrome, calcein, is typically administered by immersing individuals in a bath containing dissolved calcein. However, there are no optimal dosing studies for echinoderms. We used a 3 x 4-factorial (ANOVA) experiment to test whether lower concentrations of calcein (20 mg·l-1 = 100%, 10 mg·l-1 = 50%, 2 mg·l-1 = 10%) and shorter soaking times (24 h, 12 h, 4 h & 2 h) produced detectable fluorescence in the green sea urchin Strongylocentrotus droebachiensis (Müller, 1776). Juvenile sea urchins (n = 72) from a single hatchery spawning cohort were standardized by size (mean and variance) into 12 groups. These groups were randomly assigned to the 12 factorial treatments and individual replicates randomly distributed in a circulating sea table. During calcein treatment, individual urchin replicates were isolated in 500 ml beakers, maintained at a constant temperature, and returned to the sea table after 24 hours. Replicates were then kept in controlled conditions for ten days after the treatment. Urchins were then euthanized, processed with sodium hypochlorite, rinsed, and dried. We examined the demipyramids of Aristotle's lantern with UV illumination and quantified the intensity of fluorescent marks with ImageJ software. Demipyramids from replicates soaked in 50% for 12 hours were not significantly different from those in 100% at 24 hours. This lower exposure treatment combination may ameliorate any negative effects of calcein exposure.

description: Sustained activity-dependent synaptic modifications require protein synthesis. Although proteins can be synthesized locally in dendrites, long-term changes also require nuclear signaling. Amyloid-β protein precursor intracellular domain-associated protein-1 (AIDA-1), an abundant component of the biochemical postsynaptic density fraction, contains a nuclear localization sequence, making it a plausible candidate for synapse-to-nucleus signaling. We used immunohistochemistry to study the regional, cellular, and subcellular distribution of AIDA-1. Immunostaining was prominent in the hippocampus, cerebral cortex, and neostriatum. Along with diffuse staining of neuropil, fluorescence microscopy revealed immunostaining of excitatory synapses throughout the forebrain, and immunoreactive puncta within and directly outside the nucleus. Presynaptic staining was conspicuous in hippocampal mossy fibers. Electron microscopic analysis of material processed for postembedding immunogold revealed AIDA-1 label within postsynaptic densities in both hippocampus and cortex. Together with previous work, these data suggest that AIDA-1 serves as a direct signaling link between synapses and the nucleus in adult rat brain.

description: The nuclear symmetry energy coefficient (including the coefficient $a_{\rm sym}^{(4)}$ of $I^{4}$ term) of finite nuclei is extracted by using the differences of available experimental binding energies of isobaric nuclei. It is found that the extracted symmetry energy coefficient $a^{*}_{\rm sym}(A,I)$ decreases with increasing of isospin asymmetry $I$, which is mainly caused by Wigner correction, since $e^{*}_{\rm sym}$ is the summation of the traditional symmetry energy $e_{\rm sym}$ and the Wigner energy $e_{\rm W}$. We obtain the optimal values $J=30.25\pm0.10$ MeV, $a_{\rm ss}=56.18\pm1.25$ MeV, $a_{\rm sym}^{(4)}=8.33\pm1.21$ MeV and the Wigner parameter $x=2.38\pm0.12$ through the polynomial fit to 2240 measured binding energies for nuclei with $20 \leq A \leq 261$ with an rms deviation of 23.42 keV. We also find that the volume symmetry coefficient $J\simeq 30$ MeV is insensitive to the value $x$, whereas the surface symmetry coefficient $a_{\rm ss}$ and the coefficient $a_{\rm sym}^{(4)}$ are very sensitive to the value of $x$ in the range $1\leq x\leq 4$. The contribution of $a_{\rm sym}^{(4)}$ term increases rapidly with increasing of isospin asymmetry $I$. For very neutron-rich nuclei, the contribution of $a_{\rm sym}^{(4)}$ term will play an important role.

description: Synaptic function depends on interactions among sets of proteins that assemble into complex supramolecular machines. Molecular biology, electrophysiology, and live-cell imaging studies have provided tantalizing glimpses into the inner workings of the synapse, but fundamental questions remain regarding the functional organization of these “nano-machines.” Electron tomography reveals the internal structure of synapses in three dimensions with exceptional spatial resolution. Here we report results from an electron tomographic study of axospinous synapses in neocortex and hippocampus of the adult rat, based on aldehyde-fixed material stabilized with tannic acid in lieu of postfixation with osmium tetroxide. Our results provide a new window into the structural basis of excitatory synaptic processing in the mammalian brain.

description: For the past few years, we have observed the central half parsec of our Galaxy in the mid-infrared from 2.8 to 5.1 micron. Our aim is to improve our understanding of the direct environment of SgrA*, the supermassive blackhole at the centre of the Milky Way. This work is described in the present paper and by Moultaka et al. 2015 (submitted). Here, we focus on the study of the spatial distribution of the 12CO ice and gas-phase absorptions. We observed the central half parsec with ISAAC spectrograph located at the UT3/VLT ESO telescope in Chile. The slit was placed along 22 positions arranged parallel to each other to map the region. We built the first data cube in this wavelength range covering the central half parsec. The wavelength interval of the used M-band filter ranges from 4.6 to 5.1 micron. It hosts the P- and R- branches of the ro-vibrational transitions of the gaseous 12CO and 13CO, as well as the absorption band attributed to the 12CO ice at 4.675 micron. Using two calibrators, we could disentangle the local from the line-of-sight absorptions and provide a first-order estimate of the foreground extinction. We find residual ices and gase-phase CO that can be attributed to local absorptions due to material from the interstellar and/or the circumstellar medium of the central parsec. Our finding implies temperatures of the order of 10 to 60K which is in agreement with the presence of water ices in the region highlighted by Moultaka et al. (2004, 2005).

description: The authors indicate the presence of an annelid polychete (family Opheliidae) long about 1 cm (-1/3 inch), in the sands of Roscoff (Brittany).
The amplitude of variations concerning its morphological characters allows us to identify it with Ophelia rathkei Me Intosh 1908 as well as with Ophelia remaní Augener 1939 and Ophelia cluthensis Me Guire 1935 which are known from the British Isles and from Germany; these polychetes form thus one single species (with 8 to 10 pairs of gills), living in well oxygenized, homometrical fine sands (median from 200 to 300) of neap-tide oscillation zone.
Sands with this Ophelia finds intermittend between Ophelia bicornis (sands in the upper part) and those containing Travesía forbesi and Ophelia neglecta populations (in the lower part).

description: In this paper I review three different positions on the wave function, namely: nomological realism, dispositionalism, and configuration space realism by regarding as essential their capacity to account for the world of our experience. I conclude that the first two positions are committed to regard the wave function as an abstract entity. The third position will be shown to be a merely speculative attempt to derive a primitive ontology from a reified mathematical space. Without entering any discussion about nominalism, I conclude that an elimination of abstract entities from one's ontology commits one to instrumentalism about the wave function, a position that therefore is not as unmotivated as it has seemed to be to many philosophers.

description: An histochemical and histoenzymiological study of the accessory boring organ in Purpura lapillus (L.) leads to the following results:
lipids, fatty acids, lipase and alkaline phosphatase are present as well in a
resting organ as in a drilling one;
organ at rest is very rich in glycogen and poor in carbonic anhydrase in the glandular cells, the cilia of the gland being always free of this enzyme;
the working organ is poor in glycogen and, on the contrary, full of carbonic anhydrase, not only in the glandular cells but also and chiefly on the ciliature of the accessory boring organ, the secretion of which acts on the shell to bore. This last result inclines to believe that it is this enzyme which is responsible of the shell-boring of preys by Purpura lapillus(L.).

description: The sodium-driven chloride/bicarbonate exchanger (NDCBE), a member of the SLC4 family of bicarbonate transporters, was recently found to modulate excitatory neurotransmission in hippocampus. By using light and electron microscopic immunohistochemistry, we demonstrate here that NDCBE is expressed throughout the adult rat brain, and selectively concentrates in presynaptic terminals, where it is closely associated with synaptic vesicles. NDCBE is in most glutamatergic axon terminals, and is also present in the terminals of parvalbumin-positive γ-aminobutyric acid (GABA)ergic cells. These findings suggest that NDCBE can regulate glutamatergic transmission throughout the brain, and point to a role for NDCBE as a possible regulator of GABAergic neurotransmission.

description: Game theory provides a general mathematical background to study the effect of pair interactions and evolutionary rules on the macroscopic behavior of multi-player games where players with a finite number of strategies may represent a wide scale of biological objects, human individuals, or even their associations. In these systems the interactions are characterized by matrices that can be decomposed into elementary matrices (games) and classified into four types. The concept of decomposition helps the identification of potential games and also the evaluation of the potential that plays a crucial role in the determination of the preferred Nash equilibrium, and defines the Boltzmann distribution towards which these systems evolve for suitable types of dynamical rules. This survey draws parallel between the potential games and the kinetic Ising type models which are investigated for a wide scale of connectivity structures. We discuss briefly the applicability of the tools and concepts of statistical physics and thermodynamics. Additionally the general features of ordering phenomena, phase transitions and slow relaxations are outlined and applied to evolutionary games. The discussion extends to games with three or more strategies. Finally we discuss what happens when the system is weakly driven out of the "equilibrium state" by switching on non-potential components representing games of cyclic dominance.

description: Calcium/calmodulin-dependent protein kinase II (CaM-KII) plays a key role in N-methyl-D-aspartate (NMDA) receptor-dependent long-term synaptic plasticity; its location is critical for signal transduction, and may provide clues that further elucidate its function. We therefore examined the subcellular localization of CaMKII in CA1 stratum radiatum of adult rat hippocampus, by using immuno-electron microscopy after chemical fixation. When tissue was fixed quickly, the concentration of CaMKIIα (assessed by pre-embedding immunogold) was significantly higher in dendritic shafts than in spine heads. However, when tissue was fixed 5 minutes after perfusion with normal saline, the density of labeling decreased in dendritic shaft while increasing in spine heads, implying rapid translocation into the spine during brief perimortem stress. Likewise, in quickly fixed tissue, CaMKII within spine heads was found at comparable concentrations in the “proximal” half (adjacent to the spine neck) and the “distal” half (containing the postsynaptic density [PSD]), whereas after delayed fixation, label density increased in the distal side of the spine head, suggesting that CaMKII within the spine head moves toward the PSD during this interval. To estimate its distribution at the synapse in vivo, we performed postembedding immunogold staining for CaMKII in quick-fixed tissue, and found that the enzyme did not concentrate primarily within the central matrix of the PSD. Instead, labeling density peaked ∼40 nm inside the postsynaptic membrane, at the cytoplasmic fringe of the PSD. Labeling within 25 nm of the postsynaptic membrane concentrated at the lateral edge of the synapse. This lateral “PSD core” pool of CaMKII may play a special role in synaptic plasticity.

description: Increasing values of atmospheric CO2 and consequent seawater warming, as well as progressive seawater acidification constitute stressors for marine populations that may induce migrations and even local extinctions. We evaluated the separated effects of (1) high predicted temperature levels and (2) low predicted pH values on fertilization and early development stages of the sea urchin Paracentrotus lividus. Three treatments of temperature and pH were tested, according to current seawater conditions and values expected for next century in agreement to the IS92a IPCC scenario. We examined fertilization, cleavage rate, and 3-day larvae development at different times after insemination. We found that while warming accelerated fertilization, embryo and larval development, acidification delayed them. These findings suggest contrasting effects of both stressors, which compromise fertilization and early development of P. lividus at its southern most limit of distribution. Further studies about the combined effects of pH and temperature are required to accurately give insight into global warming effects on marine life.

description: To elucidate sexual differences in gonad size and color in sympatric two sea urchins (Strongylocentrotus nudus and Hemicentrotus pulcherrimus), we examined S. nudus and H. pulcherrimus with gametes in the gonads, in the Sargassum yezoense bed in the Oshika Peninsula, northern Honshu, Japan during July-November and September-June, respectively, from 2008 to 2010. The changes in the gonad indices of H. pulcherrimus in the Sargassum bed were compared with those in the Undaria pinnatifida and Saccharina japonica kelp bed, using a data set obtained from Ogasawara et al. (2011). The gonad indices, by sex, of S. nudus rapidly decreased from September to a minimum in November, while those of H. pulcherrimus decreased from October to a minimum in December, February or April. For both species of sea urchin, the proportion of brown-colored gonads increased with a decrease in the gonad indices during spawning. A significant positive correlation between brown-colorization and gonad size was also detected. In H. pulcherrimus, the female gonad size was smaller than that of males during the spawning stage in both the Sargassum bed and the kelp bed. Gonadal re- growth of females during post-spawning was much slower in the Sargassum bed.

description: In the first part of the paper I argue that an ontology of events is precise, flexible and general enough so as to cover the three main alternative formulations of quantum mechanics as well as theories advocating an antirealistic view of the wave function. Since these formulations advocate a primitive ontology of entities living in four-dimensional spacetime, they are good candidates to connect that quantum image with the manifest image of the world. However, to the extent that some form of realism about the wave function is also necessary, one needs to endorse also the idea that the wave function refers to some kind of power. In the second part, I discuss some difficulties raised by the recent proposal that in Bohmian mechanics this power is holistically possessed by all the particles in the universe.

description: We derive and discuss a posteriori error estimators for Galerkin and collocation IGA boundary element methods for weakly-singular integral equations of the first-kind in 2D. While recent own work considered the Faermann residual error estimator for Galerkin IGA boundary element methods, the present work focuses more on collocation and weighted- residual error estimators, which provide reliable upper bounds for the energy error. Our analysis allows piecewise smooth parametrizations of the boundary, local mesh-refinement, and related standard piecewise polynomials as well as NURBS. We formulate an adaptive algorithm which steers the local mesh-refinement and the multiplicity of the knots. Numerical experiments show that the proposed adaptive strategy leads to optimal convergence, and related IGA boundary element methods are superior to standard boundary element methods with piecewise polynomials.

description: Genetic alterations of the maternal UBE3A allele result in Angelman syndrome (AS), a neurodevelopmental disorder characterized by severe developmental delay, lack of speech, and difficulty with movement and balance. The combined effects of maternal UBE3A mutation and cell type-specific epigenetic silencing of paternal UBE3A are hypothesized to result in a complete loss of functional UBE3A protein in neurons. However, the allelic specificity of UBE3A expression in neurons and other cell types in the brain has yet to be characterized throughout development, including the early postnatal period when AS phenotypes emerge. Here we define maternal and paternal allele-specific Ube3a protein expression throughout postnatal brain development in the mouse, a species which exhibits orthologous epigenetic silencing of paternal Ube3a in neurons and AS-like behavioral phenotypes subsequent to maternal Ube3a deletion. We find that neurons downregulate paternal Ube3a protein expression as they mature and, with the exception of neurons born from postnatal stem cell niches, do not express detectable paternal Ube3a beyond the first postnatal week. By contrast, neurons express maternal Ube3a throughout postnatal development, during which time localization of the protein becomes increasingly nuclear. Unlike neurons, astrocytes and oligodendrotyes biallelically express Ube3a. Notably, mature oligodendrocytes emerge as the predominant Ube3a-expressing glial cell type in the cortex and white matter tracts during postnatal development. These findings demonstrate the spatiotemporal characteristics of allele-specific Ube3a expression in key brain cell types, thereby improving our understanding of the developmental parameters of paternal Ube3a silencing and the cellular basis of AS.

MORPHOGENÈSE DU TERMEN ET DES ÉPINES DANS LES ZOÉCIES D'ELECTRA VERTICILLATA (ELLIS ET SOLANDER) (BRYOZOAIRE CHILOSTOME, ANASCA)

description: The author studies, in the zoecia of the Bryozoa Chilostomata Electra verticillata (Anasca, Electridae), the structure and genesis of the rims of the area (termen and spines), through morphology and histology. The termen issues from a curb of the body wall from which the conical draughts of the spines do come out quite synchronically. Meanwhile these elements acquire their respective complications, particularly the sinuosities of the termen and its sub-areal layer are closely related to the building of the "embase" of the spines, underlying at their insertion point. The direct relations of the spines to the purely zoecial walls and especially the lack in the place of pore plates bearing wall lead to considering them as simple ornementations, not at all as heterozoïds.

description: Experimental tests of QCD through its predictions for the strange-quark content of the proton have been drastically restricted by our lack of knowledge of the violation of charge symmetry (CSV). We find unexpectedly tiny CSV in the proton's electromagnetic form factors by performing the first extraction of these quantities based on an analysis of lattice QCD data. The resulting values are an order of magnitude smaller than current bounds on proton strangeness from parity violating electron-proton scattering experiments. This result paves the way for a new generation of experimental measurements of the proton's strange form factors to challenge the predictions of QCD.
Advances in the study of intraclonal variation in Gracilaria chilensis (Rhodophyta)
Creators: name: SANTELICES, Bernabé
Publisher: name: Station Biologique de Roscoff (SBR)
Year: 2001

description: The search for causes of intra-clonal variation in Gracilaria chilensis has lead to studying the effects of
 physiological and development factors, pathogenic infections, genetic instability and sporeling coalescence on this response.
 Results suggest intra-clonal variation is a frequent process that could explain morphological variation among thalli,
 physiological variation among ramets and local population variation. Intra-clonal variation, in addition, has significant
 importance with respect to strain selection of economically important seaweeds.
Geschichtsbilder sehen. Narrative Formen als Gegenstand des Lernens mit Geschichten

description: Im Zuge einer ikonischen Wende in den Geisteswissenschaften hat das Visuelle an Bedeutung für den kritischen Umgang mit Bildungsmedien wie Schulbücher und deren Inhalte gewonnen. Während frühe Arbeiten vor allem eine Kritik an der Vorstellung des Bildes als Anhängsel des Texts übten, erlaubte die Ausweitung des Bildbegriffs eine Annäherung verschiedener semiotischer Ansätze. Am Beispiel von Geschichtsschulbüchern stellt sich der Aufsatz die Frage inwieweit (Schulbuch)Narrative als Bilder verstanden werden können und wie ein solches Verständnis neue methodische Perspektiven auf das Lernen mit dem Bildungsmedium eröffnet.

description: The 53 kDa insulin receptor substrate protein (IRSp53) is highly enriched in the brain. Despite evidence that links mutations of IRSp53 with autism and other neuropsychiatric problems, the functional significance of this protein remains unclear. We used light and electron microscopic immunohistochemistry to demonstrate that IRSp53 is expressed throughout the adult rat brain. Labeling concentrated selectively in dendritic spines, where it was associated with the postsynaptic density (PSD). Surprisingly, its organization within the PSD of spiny excitatory neurons of neocortex and hippocampus differed from that within spiny inhibitory neurons of neostriatum and cerebellar cortex. The present data support previous suggestions that IRSp53 is involved in postsynaptic signaling, while hinting that its signaling role may differ in different types of neurons.
Schulpolitik im besetzten Polen 1939 - 1945
Creators: name: Hansen, Georg
Publisher: name: bildungsforschung

description: Die Schulpolitik im besetzten Polen während des Zweiten Weltkriegs ist Teil einer neuartigen Kolonisierungspolitik. Kriegsziel ist die Einverleibung und Eindeutschung weiter bisher polnischer Territorien. Die Bevölkerung wird ermordet, deportiert, zeitweise geduldet oder eingedeutscht. Eine Schulpolitik der extremen ethnischen Selektion soll diesem Kriegsziel dienen. Diese rassistisch ausgerichtete Politik legt den Zugang zu formalisierter Bildung bzw. den teilweisen oder gänzlichen Ausschluss vom Zugang für ethnisch definierte Bevölkerungsgruppen fest. Im Ergebnis handelt es sich für fast alle Jugendlichen um eine drastische Bildungsbegrenzung.

description: State-space models (SSMs) are increasingly used in ecology to model time-series such as animal movement paths and population dynamics. This type of hierarchical model is often structured to account for two levels of variability: biological stochasticity and measurement error. SSMs are flexible. They can model linear and nonlinear processes using a variety of statistical distributions. Recent ecological SSMs are often complex, with a large number of parameters to estimate. Through a simulation study, we show that even simple linear Gaussian SSMs can suffer from parameter- and state-estimation problems. We demonstrate that these problems occur primarily when measurement error is larger than biological stochasticity, the condition that often drives ecologists to use SSMs. Using an animal movement example, we show how these estimation problems can affect ecological inference. Biased parameter estimates of a SSM describing the movement of polar bears (\textit{Ursus maritimus}) result in overestimating their energy expenditure. We suggest potential solutions, but show that it often remains difficult to estimate parameters. While SSMs are powerful tools, they can give misleading results and we urge ecologists to assess whether the parameters can be estimated accurately before drawing ecological conclusions from their results.

description: Microtia is treated with rib cartilage sculpting and staged procedures; though aesthetically pleasing, these constructs lack native ear flexibility. Tissue-engineered (TE) elastic cartilage may bridge this gap; however, TE cartilage implants lead to hypertrophic changes with calcification and loss of flexibility. Retaining flexibility in TE cartilage must focus on increased elastin, maintained collagen II, decreased collagen X, with prevention of calcification. This study compares biochemical properties of human cartilage to TE cartilage from umbilical cord mesenchymal stem cells (UCMSCs). Our goal is to establish a baseline for clinically useful TE cartilage.
Monotheismus im Widerstreit. Zur jüngeren Debatte um Glaube und Gewalt

description: Gegenwärtig wird in der Orientierung der "abrahamitischen" Religionen ein Grund für die Entfremdung zwischen den Kulturen gesehen. Auch eine neue Sichtweise der Religionsgeschichte, die "Mosaische Unterscheidung" Assmanns, hat zu einer kritischen Betrachtung des Monotheismus beigetragen. Ein Blick in die biblische Literatur zeigt jedoch, dass hier Vorstellungen der Umwelt aufgenommen werden und Gegenentwürfe zur Darstellung kommen. Und diese kommen nicht ohne einen gerechten und allmächtigen Gott ausund zeigen die Wirklichkeit eines Gottes, der auf unbegrenzte und unbegreifliche Weise alle Teile seiner Schöpfung liebt.

The application of sequences of the ribosomal cistron to the systematics and classification of the florideophyte red algae (Florideophyceae, Rhodophyta)
Creators: name: HARPER, James T.
name: SAUNDERS, Gary W.
Publisher: name: Station Biologique de Roscoff (SBR)
Year: 2001

description: This review discusses the impact that molecular studies of the genic and spacer regions of the ribosomal cistron
 have had on the systematics and classification of the florideophyte red algae. Each ribosomal cistron consists of a non-
 transcribed spacer region (NTS), an external transcribed spacer region (ETS), the small-subunit (SSU) rRNA gene, internal
 transcribed spacer (ITS 1) region 1, the 5.8S rRNA gene, internal transcribed spacer (ITS 2) region 2, and the large-subunit
 (LSU) rRNA gene. To date, molecular investigations on the Rhodophyta that utilize the ribosomal cistron have been based
 largely on the SSU and, to a lesser extent, the ITS regions. We then outline the methods and procedures we use to obtain
 sequence data from the various regions of the ribosomal cistron. A discussion of recent advances in florideophyte systematics
 within the four florideophyte lineages outlined by Saunders & Kraft (1997) is presented. We then close the review with an
 introduction to, and discussion of the potential utility of sequences of the LSU for resolving relationships within the
 Rhodophyta.
title: The Transformation of Security Institutions in Latin America: The Market for Force of Commercial Military Security Actors
Creators: name: Penel, Charlotte
Publisher: name: University of Liverpool Repository
Year: 2026

description: This thesis provides both an empirical and theoretical contribution to the literature on commercial military security actors (CMSAs) in Latin America. Firstly, it provides an empirical understanding on the presence and activities of CMSAs in the region. This contribution comes from the ‘Latin American and Caribbean Commercial Military and Security Actors Dataset’ that I have created and captures 1,509 contracts from 1980 to 2016 in 14 Latin American and Caribbean countries providing insight into when and who these actors have worked for, the types of services they provide, as well as information on the operators and companies of CMSAs. The thesis also provides a theoretical contribution by providing insight into how private security companies have developed in the security institution in the region. It illustrates how it is important to take into account a regional approach to understanding this phenomenon due to regional characteristics that can play a part in the outcome. It also takes a historical institutionalist approach to understanding this development, looking into changes that took place in security institutions in the region. Through historical institutionalism, I have developed a causal mechanism that can explain the outcome, which not only looks at the correlation but also the reason for this correlation, in other words, how the causal process occurred and the specific chain of events. The causal mechanism includes the critical juncture of neoliberalism and democratization, followed by three parts, which are: 1. a lack of public trust in the state security institution, 2. public insecurity, 3. a supply and demand for private security companies. Each part of the causal mechanism, using process-tracing, were tested through three case studies: Argentina, Bolivia, and El Salvador. All parts of the causal mechanism were found to be present, providing validity to the hypothesised causal mechanism.
