The organic signatures of life on Mars

description: The search for extraterrestrial life is one of the ultimate challenges for science. Mars was the only planet ever to be targeted for a life searching mission (NASA’s Viking) and still remains the main focus regarding the search of extraterrestrial life. This thesis aims to find out what are the best locations on Mars to search for biosignatures of life (amino acids) and contribute to the preparation of future space missions to the Red Planet. In this thesis, two Mars soil analogues were studied: Rio Tinto in Spain and the hypersaline lakes of the Yilgarn Craton in Western Australia. Investigation of their mineralogical, microbiological and biosignature content provided hints of what future life searching missions may find in similar environments on Mars. A third set of samples, comprised of mineral standards that are relevant in the martian surface, was also used to study the influence of mineralogy in the preservation of biosignatures under simulated Mars conditions. Overall, results show that both Mars soil analogues contained minerals that are commonly found on Mars, such as iron oxides, clays and evaporites. Generally, microbiology analyses show that life on Mars was/may be based on iron metabolism and/or halophilic. No obvious correlations were found between mineralogy, microbiology communities and biosignature content on both analogues. Detection of biosignatures was not straightforward even when life is known to be present in the sediments. Therefore, in situ detection of biosignatures on Mars may be a very difficult task and frequent sampling should be considered in future life searching missions. Results from Mars Chamber simulations suggest that locations containing sulfate minerals and smectite clays should be priority targets for the search of organic signature of martian life, due to their potential to preserve biosignatures and the fact that they usually indicate the presence of habitable environments.

description: Models based on Universal Extra Dimensions predict Kaluza-Klein (KK) excitations of all Standard Model (SM) particles. We examine the pair production of KK excitations of top- and bottom-quarks at the Large Hadron Collider. Once produced, the KK top/bottom quarks can decay to $b$-quarks, leptons and the lightest KK-particle, $γ_1$, resulting in 2 $b$-jets, two opposite sign leptons and missing transverse momentum, thereby mimicing top-pair production. We show that, with a proper choice of kinematic cuts, an integrated luminosity of 100 fb$^{-1}$ would allow a discovery for an inverse radius upto $R^{-1} = 750$ GeV.

description: Anion exchange membranes (AEMs) play an important role in improving the performance and efficiency of anion exchange membrane fuel cells (AEMFCs). A sequence of composite anion exchange membranes (AEMs) consisting of poly(vinyl alcohol) (PVA) as a backbone polymer and different approaches for introducing functional groups has been prepared by a solution casting method. The performance of composite AEMs was evaluated using water uptake, swelling degree, and OH- conductivity measurement. QPVA/PDDA composite AEMs acquired the highest hydroxide conductivity, water uptake, and swelling degree. This study demonstrates that the PVA-based AEMs has the potential for fuel cell application.

description: We study the optic control for birefringence of a polarized light by an atomic ensemble with a tripod configuration, which is mediated by the electromagnetically induced transparency with a spatially inhomogeneous laser. The atom ensemble splits the linearly polarized light ray into two orthogonally-polarized components, whose polarizations depend on quantum superposition of the initial states of the atom ensemble. Accompanied with this splitting, the atom ensemble behaves as a birefringent lens, which allows one polarized light ray passing through straightly while focus another orthogonal to this polarization with finite aberration of focus.

description: We search for asymptotic safety in a Yukawa system with a chiral $U(N_L)_L\otimes U(1)_R$ symmetry, serving as a toy model for the standard-model Higgs sector. Using the functional RG as a nonperturbative tool, the leading-order derivative expansion exhibits admissible non-Ga\ssian fixed-points for $1 \leq N_L \leq 57$ which arise from a conformal threshold behavior induced by self-balanced boson-fermion fluctuations. If present in the full theory, the fixed-point would solve the triviality problem. Moreover, as one fixed point has only one relevant direction even with a reduced hierarchy problem, the Higgs mass as well as the top mass are a prediction of the theory in terms of the Higgs vacuum expectation value. In our toy model, the fixed point is destabilized at higher order due to massless Goldstone and fermion fluctuations, which are particular to our model and have no analogue in the standard model.

description: The Dinaledi Chamber of the Rising Star cave system has yielded a large assemblage of fossil hominin material, attributed to Homo naledi. The unusual taphonomic and geological situation of the assemblage suggested that the remains may have been deliberately deposited in the chamber. However, the route and mechanism of deposition of the remains within the Dinaledi Chamber are still uncertain. During the 2017—2018 field seasons, we expanded explorations of the passages surrounding the Dinaledi Chamber. These explorations improved our understanding of the cave’s spatial complexity, necessitating a revision of the way the spaces are named and described. The work supported the hypothesis that there is no alternate entrance into the system other than the Chute. The work also identified new fossil deposits in several remote passages, three of which contain material attributable to H. naledi. Here, we clarify the definition of the Dinaledi Subsystem and provide terminology for new fossil localities found in this portion of the Rising Star cave system. These results emphasize the complex depositional environment of the Dinaledi Subsystem and raise new questions about the process and timing of the fossil accumulations.

description: Teil 1: Der Zweck einer Variantenuntersuchung besteht darin, die „günstigste“ Lösung der Abwasserentsorgung für ein definiertes Untersuchungsgebiet zu finden. Bei der herkömmlichen Vorgehensweise zur Lösung dieser Problemstellung werden ex ante unterschiedliche Möglichkeiten der Abwasserentsorgung (Varianten) definiert und diese anschließend miteinander verglichen. Der Einsatz dieser Methodik birgt vorallem in ländlichen Untersuchungsgebieten - die sich durch die Existenz einer großen Anzahl an Varianten auszeichnen - eine Schwachstelle in sich, da es in diesen Fällen wohl kaum möglich sein wird alle denkbaren Handlungsalternativen zu berücksichtigen. In diesem Beitrag - in dem der Aspekt der Kostenminimierung im Vordergrund steht - wird ein Optimierungsverfahren vorgestellt mit dessen Hilfe die soeben erwähnte Schwachstelle der herkömmlichen Variantenvergleichsrechnung überwunden werden kann.

Aus dieser Analyse und einer welt-anschaulichen Position, die durch die Konzepte Mit-, Sozial- und Nachweltverträglichkeit geprägt ist, ergibt sich in natürlicher Weise ein Gegen-konzept. Dieses zeigt zumindest, wie meilenweit die heutige Industriegesellschaft von einem nachhaltigen Umgang mit dem Lebenselement Wasser sogar im ländlichen Raum entfernt ist, und wie schnell sie sich von einem Pfad der Nachhaltigkeit weiter entfernt. Die Umsetzung eines solchen Gegenkonzeptes bleibt solange fragwürdig, solange der im Kant’schen Sinn mündige Bürger weiterhin eine Einzelerscheinung bleibt.

description: This paper can be thought of as an extended introduction to arXiv:0708.3398; nevertheless, most of its results are not covered by loc. cit. We consider the derived categories of DG-modules, DG-comodules, and DG-contramodules, the coderived and contraderived categories of CDG-modules, the coderived categories of CDG-comodules, and the contraderived categories of CDG-contramodules. The equivalence between the latter two categories (the comodule-contramodule correspondence) is established. Nonhomogeneous Koszul duality or "triality" (an equivalence between exotic derived categories corresponding to Koszul dual (C)DG-algebra and CDG-coalgebra) is obtained in the conilpotent and nonconilpotent versions. Various $A_\infty$-structures are considered, and a number of model category structures are described. Homogeneous Koszul duality and $D$-$Ω$ duality are discussed in the appendices.

description: Homo naledi is known from the Rising Star cave system, South Africa, where its remains have previously been reported from two localities: the Dinaledi Chamber (U.W. 101) and Lesedi Chamber (U.W. 102). Continued exploration of the cave system has expanded our knowledge of the Dinaledi Chamber and its surrounding passageways (the Dinaledi Subsystem), leading to the discovery of new fossil localities. This paper discusses the fossil assemblage from the locality designated U.W. 110. This locality is within a narrow fissure of the Dinaledi Subsystem approximately 12 meters southwest of the 2013–2014 excavation. Fossil remains recovered from this locality include six hominin teeth and 28 cranial fragments, all consistent with a single immature hominin individual. The dental morphology of the new specimens supports attribution to H. naledi. This is the first immature individual of H. naledi to preserve morphological details of the calvaria in association with dental evidence. This partial skull provides information about the maturation of H. naledi and will be important in reconstructing the developmental sequence of immature remains from other H. naledi occurrences. This is the third locality described with H. naledi material in the Rising Star cave system and represents a depositional situation that resembles the Lesedi Chamber in some respects.

description: A large set of data on proton-proton differential cross sections, analyzing powers and the double polarization parameter A_NN is analyzed employing the Regge formalism. We find that the data available at proton beam momenta from 3 GeV/c to 50 GeV/c exhibit features that are very well in line with the general characteristics of Regge phenomenology and can be described with a model that includes the rho, omega, f_2, and a_2 trajectories and single Pomeron exchange. Additional data, specifically for spin-dependent observables at forward angles, would be very helpful for testing and refining our Regge model.

La ricerca, insieme all’insegnamento, ha caratterizzato fin dalla nascita, e continua a caratterizzare, la vita delle Università italiane. Questo volume vuole ripercorrere, attraverso alcuni dei ricercatori più importanti che hanno svolto le loro ricerche nell’Ateneo cagliaritano, i 400 anni dalla sua fondazione, per testimoniare la grande vitalità ma anche le difficoltà attraversate dal nostro Ateneo.

I contenuti di questo volume, presentati al convegno "La ricerca nei 400 anni dell’Università degli Studi di Cagliari”, tenutosi a Cagliari il 23 marzo 2021, insieme al video dedicato ai 400 anni di ricerca nell’Università di Cagliari, disponibile in YouTube, costituiscono una importante testimonianza della storia della ricerca nella nostra Università.

Il primo capitolo racconta le basi sulle quali è stata costruita l’Università degli studi di Cagliari e descrive la storia dei ricercatori presentati nel Video. È interessante notare in questo capitolo come le donne, pur arrivando in ritardo all’Università, abbiano trovato in questa istituzione un riconoscimento importante per il loro avanzamento culturale.

Il volume è quindi dedicato a quattro figure di rilievo che hanno operato nell’Ateneo cagliaritano nel 900: il matematico Enrico Bombieri, il medico Giuseppe Brotzu, l’archeologo Giovanni Lilliu e il fisico Antonio Pacinotti.

Si ringrazia la Rettrice Maria Del Zompo e il Rettore eletto Francesco Mola per avere fortemente voluto questo volume come futura memoria delle celebrazioni dei 400 anni dalla fondazione dell’Università degli studi di Cagliari.

description: We study the full counting statistics of charge transport through a quantum dot tunnel-coupled to one normal and one superconducting lead with a large superconducting gap. As function of the level detuning, there is a crossover from a regime with strong superconducting correlations in the quantum dot to a regime in which the proximity effect on the quantum dot is suppressed. We analyze the current fluctuations of this crossover in the shot-noise regime. In particular, we predict that the full counting statistics changes from Poissonian with charge 2e, typical for Cooper pairs, to Poissonian with charge e, when the superconducting proximity effect is present. Thus, the onset of the superconducting proximity effect is revealed by the reduction of the Fano factor from 2 to 1.

description: Antimicrobial resistance is a global concern with increases in multidrug-resistant bacteria. New coordination compounds could offer a solution. We report S-benzyl-β-(N-2-methyl-3-phenylallylidene)dithiocarbazate (HL) forming bis[S-benzyl-β-(N-2-methyl-3-phenylallylidene)dithiocarbazate]zinc(II), [Zn(L)2]; its bio-efficacy has been examined against the growth of gram-positive Staphylococcus aureus and gram-negative Escherichia coli to evaluate antimicrobial potential. The inhibition diameter results of E. coli and S. aureus were compared to standard drug (Erythromycin). Characterization by UV–vis, FT-IR, Raman, 1H NMR, 13C NMR, and mass spectroscopy revealed that [Zn(L)2] has distorted square planar geometry, coordinated through Nimine and Sthiolate. Density functional calculations of [Zn(L)2] in gas phase were performed by DFT (RB3LYP) with LanL2DZ basis set and the results are: chemical hardness (ɳ) 0.007915 eV, chemical potential (µ) 0.11643 eV, electron affinity (A) −0.10852 eV, softness (S) 7.855 eV, ionization energy (I) −0.12435 eV, electronegativity (χ) −0.11643 eV, dipole moment (D) 4.0690 Debye and with stabilization energy of −1718.1753 eV. Vibrational energy distribution analysis (VEDA)-4 software was employed for theoretical FT-IR spectrum, which yielded 237 fundamental vibrational modes. Theoretically calculated parameters like UV–vis, FT-IR, 1H NMR, 13C NMR, Raman, HOMO–LUMO energy gap and electrostatic potential were in conformity with experimental observations. The compound was docked with different receptors 1HT0, 1U3T, 1U3V, and 3S7S to find the best ligand–protein interactions.
Finite element modelling of rock cutting using a polycrystalline diamond compact cutter
Creators: name: Defoort, Thibaut
Publisher: name: Imperial College London
Year: 2018

description: This thesis focuses on three-dimensional finite element modelling of the process of rock cutting using a single polycrystalline diamond compact bit. The modelling is carried out using a modified and enhanced version of the Imperial College Geomechanics Toolkit (ICGT). First, local continuum damage mechanics (CDM) approaches are reviewed and implemented. In these approaches, cracks are not explicitly represented or modelled, but their effect is represented by a degradation in the elastic moduli, with the help of a local damage parameter. It is clearly shown, however, that although such local models perform relatively well in two dimensions, in three dimensions, fracture growth and deformation localisation becomes inhibited, and the energy needed in order propagate a fracture becomes unrealistic, as the damage is spread over too many elements. Consequently, local continuum damage mechanics is discarded, and attention is directed at models in which discrete fractures are propagated. In this approach, stress intensity factors are computed at each crack tip, and crack growth criteria are used to determine which cracks will grow, and in which directions. In order to be used for the specific problem of rock cutting, several modifications were required to the ICGT. Specifically, the geometric representation of the growing fracture is modified to account for the model boundary, namely, the top of the rock block, and the contact between the cutter and the rock. This allows for an accurate meshed representation of the geometry, a good representation of the fractures faces, and prevents fractures from propagating into the cutter. To validate, understand, and inform the numerical rock cutting simulations, physical scratch tests were performed. The novelty of these tests resides in the use of chamfered cylindrical cutters, measurement of both forces and groove widths for tests at depths of cut as high as 4 mm, and the establishment of correlations between groove dimension, cutting efficiency, and cutting aggressivity. In the last chapter, the developed modelling tool is applied to numerically model the rock cutting process. First, elastic contact between the cutter and the rock is studied. The main conclusion is that use of a low local friction coefficient results in a more accurate ratio between the predicted vertical to horizontal forces. Then, initial flaws are inserted into the rock matrix to allow for rock degradation. Only a vent crack develops, which appears to shield the other flaws from propagating, although further loading would lead to the propagation of other fractures.
Degenerate neutrality creates evolvable fitness landscapes

description: Understanding how systems can be designed to be evolvable is fundamental to research in optimization, evolution, and complex systems science. Many researchers have thus recognized the importance of evolvability, i.e. the ability to find new variants of higher fitness, in the fields of biological evolution and evolutionary computation. Recent studies by Ciliberti et al (Proc. Nat. Acad. Sci., 2007) and Wagner (Proc. R. Soc. B., 2008) propose a potentially important link between the robustness and the evolvability of a system. In particular, it has been suggested that robustness may actually lead to the emergence of evolvability. Here we study two design principles, redundancy and degeneracy, for achieving robustness and we show that they have a dramatically different impact on the evolvability of the system. In particular, purely redundant systems are found to have very little evolvability while systems with degeneracy, i.e. distributed robustness, can be orders of magnitude more evolvable. These results offer insights into the general principles for achieving evolvability and may prove to be an important step forward in the pursuit of evolvable representations in evolutionary computation.

description: We consider in this paper a two-pulse photon echo sequence as a potential quantum light storage protocol. It is widely believed that a two-pulse scheme should lead to very low efficiency and is then not relevant for this specific application. We show experimentally by using a Tm${}^{3+}$:YAG crystal that such a protocol is on contrary very efficient and even too efficient to be considered as a good quantum storage protocol. Our experimental work allows us to point out on one side the real limitations of this scheme and on the other side its benefits which can be a source of inspiration to conceive more promising procedures with rare-earth ion doped crystals.

description: We study non-perturbative aspects of the large N duality between Chern-Simons theory and topological strings, and we find a rich structure of large N phase transitions in the complex plane of the 't Hooft parameter. These transitions are due to large N instanton effects, and they can be regarded as a deformation of the Stokes phenomenon. Moreover, we show that, for generic values of the 't Hooft coupling, instanton effects are not exponentially suppressed at large N and they correct the genus expansion. This phenomenon was first discovered in the context of matrix models, and we interpret it as a generalization of the oscillatory asymptotics along anti-Stokes lines. In the string dual, the instanton effects can be interpreted as corrections to the saddle string geometry due to discretized neighboring geometries. As a mathematical application, we obtain the 1/N asymptotics of the partition function of Chern-Simons theory on L(2,1), and we test it numerically to high precision in order to exhibit the importance of instanton effects.

The Effects of models of perceived similarity on two types of altruistic behavior in fifth grade children
Creators: name: Hops, Zona Joyce
Publisher: name: University of British Columbia
Year: 2011

description: This study examined the effect of same-sex peer models perceived as similar, neutral, or dissimilar on two types of altruistic behaviour in fifth grade children. The dependent variable was altruistic responses, operationally defined as penny donations and volunteering of service time to work on a charitable project. A two-factor design was employed for each experiment in which the three treatment conditions: model-similar, model-neutral, model-dissimilar, and the no-model control group were nested within the sex factor. A total sample of 320 subjects for both experiments was drawn from six public elementary schools in North Burnaby. The research questions for the two experiments were: 1. Does the presence of a model elicit more donations of money and service time for charitable purposes in fifth grade children than no model? 2. Does the similarity shared between the observer and model affect the donations of money and service time for charitable purposes? 3. Are there any sex differences in donating money and service time for charitable purposes? Each subject was interviewed individually by an experimenter who attempted to manipulate through a verbal description the perceptions of a peer-model. Following a brief introduction the subject observed the model play a marble game through which rewards of pennies or five-minute time tokens were dispensed on a pre-determined schedule. The subject then played a game alone and received either money or time tokens which could be contributed by dropping them into a donation can before leaving the experimental room. The no-model control group played the game alone following initial instructions from the experimenter. The data was analyzed by an ANOVA and orthogonal comparisons of the means of the different treatment groups. As hypothesized, a same-sex peer model was more effective in eliciting altruistic responses than no model. The greater the real or assumed similarity between the observer and model the more effective the model was in eliciting penny and service donations. The presence of a model perceived as similar was significantly more effective in eliciting money donations and service time than a model perceived as dissimilar. No sex differences were found in the donations of money or time to work on a charitable project.

description: Simulation design is the choice of locations in parameter space at which simulations are to be run and is the first step in building an emulator capable of quickly providing estimates of simulation results for arbitrary locations in the parameter space. We introduce an alteration to the "OALHS" design used by Heitmann et al. (2006) that reduces the number of simulation runs required to achieve a fixed accuracy in our case study by a factor of two. We also compare interpolation procedures for emulators and find that interpolation via Gaussian Process models and via the much-easier-to-implement polynomial interpolation have comparable accuracy. A very simple emulation-building procedure consisting of a design sampled from the parameter prior distribution, combined with interpolation via polynomials also performs well. Although our primary motivation is efficient emulators of non-linear cosmological N-body simulations, in an appendix we describe an emulator for the CMB temperature power spectrum publicly available as computer code.

description: This paper demonstrates that simple yet important characteristics of coevolution can occur in evolutionary algorithms when only a few conditions are met. We find that interaction-based fitness measurements such as fitness (linear) ranking allow for a form of coevolutionary dynamics that is observed when 1) changes are made in what solutions are able to interact during the ranking process and 2) evolution takes place in a multi-objective environment. This research contributes to the study of simulated evolution in a at least two ways. First, it establishes a broader relationship between coevolution and multi-objective optimization than has been previously considered in the literature. Second, it demonstrates that the preconditions for coevolutionary behavior are weaker than previously thought. In particular, our model indicates that direct cooperation or competition between species is not required for coevolution to take place. Moreover, our experiments provide evidence that environmental perturbations can drive coevolutionary processes; a conclusion that mirrors arguments put forth in dual phase evolution theory. In the discussion, we briefly consider how our results may shed light onto this and other recent theories of evolution.

description: Automated mobility (AM) involves the increased use of digital information and communication technologies in all areas of traffic and mobility, particularly in the vehicle and mobility sector, in the infrastructure, transportation and the management of mobility-related processes (pre-, on- and post-trip). To ensure that the potentials of AM, like higher efficiency and improving accessibility, meet the demands and mobility patterns of different types of people, especially vulnerable ones like kids and people with disabilities, it is essential to make children and young adults aware of this complex and diverse topic already today. Therefore, planning and development activities in the mobility sector should involve this future generation and consider their ideas and concerns. Planning and development activities should be considered from a holistic and inclusive perspective, considering a wide variety of traffic participant groups. In this context, the Austrian project AM4Kids1 creates a direct interface between children and young adults and mobility planning. The scientists and planners take the role of facilitators of knowledge and accompany an inter and transdisciplinary, multi-level exchange between disciplines, such as transport planning, social science, mobility research, and actors from the inclusion sector. In the project, age-appropriate and gender-sensitive workshops, input lectures, and educational materials were developed and implemented by the interdisciplinary consortium of sociologists, transportation planners, landscape architects, civil engineers, software developers, and legal experts for the needs of people with disabilities. This paper presents the methods applied in the corresponding project phases. Furthermore, a reflection on the achieved results and experiences from the activities in project phases 1 and 2 is provided.
Semileptonic decays of charmed and beauty baryons with sterile neutrinos in the final state

description: We obtain tree-level estimates of various differential branching ratios of heavy baryon decays with massive sterile neutrinos $ν_{x}$ in the final state. Heavy sterile neutrinos can be searched for in heavy baryon decays with missing mass as a signature as well as in fixed target experiments, where heavy baryon decays contribute to sterile neutrino production, with sterile neutrino decays as a signature. Generally, charmed baryons are found to be less promising than charmed mesons, in contrast to b-hadrons. In the latter case, branching ratios of beauty mesons and baryons into sterile neutrinos are of the same order. As a consequence, at high energies beauty baryons give contribution to sterile neutrino production comparable to the contribution of beauty mesons (up to about 15%). Experimental limits on active-to-sterile mixing are quite strong for neutrinos lighter than D-meson but for heavier neutrinos they are weaker. As an example, for neutrino masses in the range 2 GeV $\lesssim m_{ν_{x}}\lesssim 2.5$ GeV, current data imply that the bounds on $Λ_{b}$-hyperon branching ratios into sterile neutrinos are ${\rm Br}(Λ_b\toΛ_c+e^-+ν_x)\lesssim 1.3\cdot10^{-5}-1.7\cdot10^{-6}$ and ${\rm Br}(Λ_b\toΛ_c+μ^-+ν_x)\lesssim 3.9\cdot10^{-7}-1.4\cdot10^{-7}$.

description: The beta asymmetry parameter A for the pure Gamow-Teller decay of 114In is reported. The low temperature nuclear orientation method was combined with a GEANT4 based simulation code allowing for the first time to address in detail the effects of scattering and of the magnetic field. The result, A = -0.994 +/- 0.010stat +/- 0.010syst, constitutes the most accurate value for the asymmetry parameter of a nuclear beta transition to date. The value is in agreement with the Standard Model prediction of A = -1 and provides new limits on tensor type charged weak currents.

Holography and drag force in thermal plasma of non-commutative Yang-Mills theories in diverse dimensions
Creators: name: Roy, Shibaji
Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We use holography and a string probe approach to compute the drag force on a quark moving in a thermal plasma of non-commutative Yang-Mills (NCYM) theories in various dimensions. The gravity background in these cases are described by a particular decoupling limit of non-extremal (D$(p-2)$, D$p$) brane bound state system. We show how the drag force on an external quark moving in the dual NCYM theories gets corrected due to non-commutativity and as a result the effective viscosity of the plasma gets reduced. We have obtained the drag force for both small and large non-commutativity. This was known earlier for (3+1)-dimensional NCYM theory, however, we find that the corrections for the general case typically depend on the dimensionality of the NCYM theories, indicating that the structure of the drag force is non-universal.

The relationship between connotative meaning and the reading achievement of boys and girls in the second grade.
Creators: name: Johnson, Terry Dawson
Publisher: name: University of British Columbia
Year: 2011

description: From surveys of achievement in reading, it is evident that many people in our society do not learn to read adequately. It is also evident that the majority of the children who have difficulty in learning to read are boys who have emotional problems related to their reading behaviour. Through a review of the literature on identification, sex-role learning and the differential treatment of boys and girls in schools it was suggested that the numerical predominance of male over female retarded readers is related to the difference in connotative meanings that boys and girls attach to significant figures in their home and school environments. It was hypothesized that the connotative meanings that certain concepts have for boys would be significantly related to their reading ability. It was further hypothesized that no such relationship would exist for girls. To test the hypothesis measures were made of reading ability and connotative meanings certain concepts have for boys and girls in the second grade. Meaning was measured by means of the semantic differential. To assess the relative importance of the meanings of - the concepts measured as predictor variables of reading achievement, assessments of intelligence and socio-economic status were also made. Contrary to the hypothesis the findings indicated that for children in general the concepts measured seem to be more highly related to the reading achievement of girls than of boys. The one concept that appears to be significantly related to the reading achievement of both boys and girls is the female child, Janet, a literary figure in the basal reading series used in the school district selected for the study. Analysis of the data from individual classrooms suggests factors affecting reading achievement may be peculiar to a particular classroom. Future research may attempt to analyse the complex interaction of teacher, students, and reading material and then try to isolate the factors most relevant to reading achievement. Multiple regression analysis indicated that some of the concepts measured accounted for significantly more variance in reading ability than other factors such as intelligence sub-test scores and socio-economic status which are widely assumed to be related to reading ability. It was suggested that the failure to find any significant association between connotative meaning and reading achievement for boys may have been due to the level of reading ability measured by standardized reading tests. It was suggested that future research might look at the association between connotative meaning and independent and instructional levels of reading ability.

description: Ware potatoes are a staple food in the Netherlands and are consumed not only as table potatoes but also in the form of industrially processed products such as chips, crisps and chilled products. In addition, the Netherlands produces and processes large quantities of potatoes and is a major player in the global market for potatoes and potato products (Bremmer et al., 2019). The Office for Risk Assessment & Research (BuRO) has assessed the risks for plant health and food safety in the potato production chain (hereinafter: potato chain), and based on these assessments, has identified the most important findings and drawn up certain recommendations. Other risks to human health and to nature and the environment resulting from the production (cultivation, processing) of potatoes and potato products are only referred to in brief, without any detailed risk assessment being carried out for these risks.
 The potato chain risk assessment is part of a larger programme that develops systematic and periodic overviews and insights relating to the risks to people, animals, plants and nature that can occur in the production chains for food and consumer products.
