description: Many scientific and engineering challenges – ranging from pharmacokinetic drug dosage allocation and personalized medicine to marketing mix (4Ps) recommendations – require an understanding of the unobserved heterogeneity in order to develop the best decision making-processes. In this paper, we develop a hypothesis test and the corresponding p-value for testing for the significance of the homogeneous structure in linear mixed models. A robust matching moment construction is used for creating a test that adapts to the size of the model sparsity. When unobserved heterogeneity at a cluster level is constant, we show that our test is both consistent and unbiased even when the dimension of the model is extremely high. Our theoretical results rely on a new family of adaptive sparse estimators of the fixed effects that do not require consistent estimation of the random effects. Moreover, our inference results do not require consistent model selection. We showcase that moment matching can be extended to nonlinear mixed effects models and to generalized linear mixed effects models. In numerical and real data experiments, we find that the developed method is extremely accurate, that it adapts to the size of the underlying model and is decidedly powerful in the presence of irrelevant covariates.
Changing Chinese family and elder care : the practice of filial piety among ethnic immigrant families in Vancouver
Creators: name: Zeng, Xueping
Publisher: name: University of British Columbia
Year: 2018

description: Drawing on ethnographic research conducted in 2017 with Mandarin-Speaking Chinese senior migrants in Vancouver's downtown Chinatown, this thesis examines how the notion of filial piety and forms of intergenerational reciprocity are reconfigured and understood in the context of the shift of social support for the elderly shifting from the family to the state. Specifically, through income assistance and subsidized housing provided by the government, and assisted by a broad network built through friends, neighbours, and churches, the paper describes how welfare resources and social support provide a means for Chinese seniors to act strategically to deal with changes and family tensions for the sake of their families as well as for their own. My study of Chinese seniors however, suggests that it is possible for a sense of family value to coexist with a sense of individualistic values such as personal independence and lifelong productivity that are appreciated in a modern society. The forms of different values that emerged are not a reflection of dualism between the East and the West; rather, I argue these different forms of values are intertwined in overlapping process of modernism and traditionalism in immigrants to Canada. This thesis examines how intergenerational family relationships are affected by the availability of government-sponsored senior support programs, which are a resource that enables families to resolve tensions through the negotiation of coexisting values.

description: We consider the problem of computationally efficient prediction with high dimensional and highly correlated predictors when accurate variable selection is effectively impossible. Direct application of penalization or Bayesian methods implemented with Markov chain Monte Carlo can be computationally daunting and unstable. A common solution is first stage dimension reduction through screening or projecting the design matrix to a lower dimensional hyper-plane. Screening is highly sensitive to threshold choice, while projections often have poor performance in very high-dimensions. We propose targeted random projection (TARP) to combine positive aspects of both strategies. TARP uses screening to order the inclusion probabilities of the features in the projection matrix used for dimension reduction, leading to data-informed sparsity. We provide theoretical support for a Bayesian predictive algorithm based on TARP, including statistical and computational complexity guarantees. Examples for simulated and real data applications illustrate gains relative to a variety of competitors. Supplementary materials for this article are available online.

description: Disabled people on social media often experience ableist hate and microaggressions. Prior work has shown that platform moderation often fails to remove ableist hate leaving disabled users exposed to harmful content. This paper examines how personalized moderation can safeguard users from viewing ableist comments. During interviews and focus groups with 23 disabled social media users, we presented design probes to elicit perceptions on configuring their filters of ableist speech (e.g. intensity of ableism and types of ableism) and customizing the presentation of the ableist speech to mitigate the harm (e.g. AI rephrasing the comment and content warnings). We found that participants preferred configuring their filters through types of ableist speech and favored content warnings. We surface participants distrust in AI-based moderation, skepticism in AI's accuracy, and varied tolerances in viewing ableist hate. Finally we share design recommendations to support users' agency, mitigate harm from hate, and promote safety.

description: Interpretability and stability are two important features that are desired in many contemporary big data applications arising in statistics, economics, and finance. While the former is enjoyed to some extent by many existing forecasting approaches, the latter in the sense of controlling the fraction of wrongly discovered features which can enhance greatly the interpretability is still largely underdeveloped. To this end, in this paper we exploit the general framework of model-X knockoffs introduced recently in Candès, Fan, Janson and Lv (2018), which is nonconventional for reproducible large-scale inference in that the framework is completely free of the use of p-values for significance testing, and suggest a new method of intertwined probabilistic factors decoupling (IPAD) for stable interpretable forecasting with knockoffs inference in high-dimensional models. The recipe of the method is constructing the knockoff variables by assuming a latent factor model that is exploited widely in economics and finance for the association structure of covariates. Our method and work are distinct from the existing literature in that we estimate the covariate distribution from data instead of assuming that it is known when constructing the knockoff variables, our procedure does not require any sample splitting, we provide theoretical justifications on the asymptotic false discovery rate control, and the theory for the power analysis is also established. Several simulation examples and the real data analysis further demonstrate that the newly suggested method has appealing finite-sample performance with desired interpretability and stability compared to some popularly used forecasting methods.

description: The molecular gas content of local early-type galaxies is constrained and discussed in relation to their evolution. First, as part of the Atlas3D survey, we present the first complete, large (260 objects), volume-limited single-dish survey of CO in normal local early-type galaxies. We find a surprisingly high detection rate of 22%, independent of luminosity and at best weakly dependent on environment. Second, the extent of the molecular gas is constrained with CO synthesis imaging, and a variety of morphologies is revealed. The kinematics of the molecular gas and stars are often misaligned, implying an external gas origin in over a third of the systems, although this behaviour is drastically diffferent between field and cluster environments. Third, many objects appear to be in the process of forming regular kpc-size decoupled disks, and a star formation sequence can be sketched by piecing together multi-wavelength information on the molecular gas, current star formation, and young stars. Last, early-type galaxies do not seem to systematically obey all our usual prejudices regarding star formation, following the standard Schmidt-Kennicutt law but not the far infrared-radio correlation. This may suggest a greater diversity in star formation processes than observed in disk galaxies. Using multiple molecular tracers, we are thus starting to probe the physical conditions of the cold gas in early-types.

Studies on the capital market consequences of financial reporting weaknesses
Creators: name: Wang, Jing
Publisher: name: University of British Columbia
Year: 2018

description: This thesis is a collection of two studies on the capital market consequences of financial reporting weaknesses. Chapter 2 examines the change in voluntary disclosure of internal control deficiencies (ICD) by IPO firms after the JOBS Act. The JOBS Act postponed the compliance deadline of internal control audits after IPO and increased the number of small IPO firms with potential ICD. I find that IPO firms are more likely to disclose ICD after the JOBS Act. Further, post-JOBS IPO firms who are willing to disclose ICD experience lower underpricing. These results are consistent with a dynamic view that as investors rationally update the belief of increasing “lemons” in the IPO population after the JOBS Act, IPO firms become more forthcoming with ICD disclosure. Chapter 3, co-authored with Professors Weili Ge, Dawn Matsumoto, and Jenny Li Zhang, examines the stock market consequences of disclosing accounting irregularities for U.S. listed foreign firms. We find that foreign firms experience significantly more negative two-day stock market reactions following restatement announcements than U.S. firms. Moreover, for a sample of foreign firms that are listed on both a U.S. and home country stock exchange, we find that restating firms’ U.S. investors react more negatively to the same restatement than their home-country investors. This differential market reaction appears related to firm-specific information frictions that are greater for foreign firms than U.S. firms. We also find a geographic contagion effect as non-restating firms from the same country experience significant stock price declines following restatements. Within a country-year, this contagion effect is concentrated among firms with lower accrual quality, suggesting that foreign firms’ restatements cause investors to alter their assessment of the earnings quality of non-restating firms from the same country. Collectively, our results suggest that accounting irregularities cause U.S. investors to reassess the information risk associated with foreign firms.

description: Plasmodium of \emph{Physarum polycephalum} is a single cell visible by unaided eye. The plasmodium's foraging behaviour is interpreted in terms of computation. Input data is a configuration of nutrients, result of computation is a network of plasmodium's cytoplasmic tubes spanning sources of nutrients. Tsuda et al (2004) experimentally demonstrated that basic logical gates can be implemented in foraging behaviour of the plasmodium. We simplify the original designs of the gates and show --- in computer models --- that the plasmodium is capable for computation of two-input two-output gate $ \to $ and three-input two-output $ \to < \bar{x}yz, x+y+z>$. We assemble the gates in a binary one-bit adder and demonstrate validity of the design using computer simulation.

title: Validation of a Model Examining the Six Primary Methods of Influencing Lawyer’s Professionalism Behaviour
Creators: name: Manzer, Alison
Publisher: name: University of Reading
Year: 2021

description: This thesis seeks to examine the relative effect of the licensing requirements related to professionalism for the practice of law and the six behaviour influences that have been identified by the literature as being used in the context of that regulation to positively direct lawyers’ professionalism behaviour. There are four direct licensing requirements and two aspects of delivery identified by the literature. Professionalism for law practice as the dependent variable has been defined for the research question as the acceptance or rejection of a client retainer in circumstances considering conflict of interest. A questionnaire and score for professionalism was created using ten questions and scoring responses as correct if the decision was consistent with court cases used to develop the questions. An empirical study using the survey method was selected for the research. The survey was distributed across the US and Canada to lawyers and law students in available legal professional associations and law firms. The survey research and resulting data was designed and used to test hypothesis developed from the literature using two models illustrating how the six influences relate to each other and to the dependent variable of professionalism. This study was developed to specifically address the literature-identified gap of a lack of empirical research into the effect of the six influences on professionalism behaviour. My results show that the six influences are collinear and as such, independent effects of each on the dependent variable cannot be established consistently in a single model. Rather, I show that each of the six behaviour influences impact the dependent variable of professionalism in separate estimations. There are contributions from the research to research methodology, scale development and suggestions of more efficient management techniques. The data and analysis also provided a basis for concluding that lawyers tend to favour professional appearance over economic advantage. A lack of effect from personality and demographics was also a significant finding.
How granular materials deform in quasistatic conditions

description: Based on numerical simulations of quasistatic deformation of model granular materials, two rheological regimes are distinguished, according to whether macroscopic strains merely reflect microscopic material strains within the grains in their contact regions (type I strains), or result from instabilities and contact network rearrangements at the microscopic level (type II strains). We discuss the occurrence of regimes I and II in simulations of model materials made of disks (2D) or spheres (3D). The transition from regime I to regime II in monotonic tests such as triaxial compression is different from both the elastic limit and from the yield threshold. The distinction between both types of response is shown to be crucial for the sensitivity to contact-level mechanics, the relevant variables and scales to be considered in micromechanical approaches, the energy balance and the possible occurrence of macroscopic instabilities

description: The Shortage of Donors for Organ Transplant is severe in Hong Kong. This paper envisions a potential resolution of this critical issue by implementing a sustainable social design strategy based on human affects of empathy and sympathy. As a matter-of-fact, many studies have been done on measuring attitudes and commitment to organ donation while other studies focused on the promotion of the organ donor card. Those surveys pointed out a discrepancy between positive attitude and low commitment rate to donation. This paper is to make a case for a new Organ Donation scheme which embraces emotional, functional and spiritual needs of both patients and potential donors. The scheme involves collaborative networks and interpersonal channels of communication. It results in a viral marketing strategy which involves empathy and sympathy as stimuli of the altruistic behaviors.

description: The Wavelength-shifting Optical Module (WOM) is a novel photosensor concept for the instrumentation of large detector volumes with single-photon sensitivity. The key objective is to improve the signal-to-noise ratio, which is achieved by decoupling the photosensitive area of a sensor from the cathode area of its photomultiplier tube (PMT). The WOM consists of a transparent tube with two PMTs attached to its ends. The tube is coated with wavelength-shifting paint that absorbs ultraviolet photons with nearly 100% efficiency. Depending on the environment, e.g., air (ice), up to 73% (41%) of the subsequently emitted optical photons can be captured by total internal reflection and propagate towards the PMTs, where they are recorded. The optical properties of the paint, the geometry of the tube, and the coupling of the tube to the PMTs have been optimized for maximal sensitivity based on theoretical derivations and experimental evaluations. Prototypes were built to demonstrate the technique and to develop a reproducible construction process. Important measurable characteristics of the WOM are the wavelength-dependent effective area, the transit time spread of detected photons, and the signal-to-noise ratio. The WOM outperforms bare PMTs, especially with respect to the low signal-to-noise ratio with an increase of a factor up to 8.9 in air (5.2 in ice). Since the gain in sensitivity is mostly in the UV regime, the WOM is an ideal sensor for Cherenkov and scintillation detectors.

description: Car sharing, which is regarded as a sustainable transport system, has been evidently operating very well in urban areas where public transport is well established. In Sydney, Australia, car sharing is used by different people with different motivations to join. As a result, there is a range of values expressed by its members related to their experiences of being a car sharing member. The paper aims to explore perceived values about car sharing as a sustainable system. A qualitative study using surveys, interviews, visual diaries/workbook, collage making, and design workshops was carried out to portray the expressions of values and to highlight different aspects of car sharing design that strongly relate to those values. Car sharing has satisfied individualism and also the values of sharing. It gives personal independence yet interdependence as well. It also allows for the emotions of a product experience although it is not a personal possession.

to engage children living with diabetes, as well as their friends and parents, in personal health management. Diabetes has multi-leveled health and life style management requirements, and employing a game format can simplify complex concepts in appealing ways and motivate appropriate behavior. The students applied participatory design research methodologies to co- design with subject matter experts, educators, care providers, and end-users. The students utilized game design strategy, character design, and storytelling to develop an emotionally connected and fun activity where game players interact with each other while learning about personal health management. The authors summarized this collaborative design process and shared the learning experiences of the students.
Radial Stellar Pulsation and 3D Convection. I. Numerical Methods and Adiabatic Test Cases

description: We are developing a 3D radiation hydrodynamics code to simulate the interaction of convection and pulsation in classical variable stars. One key goal is the ability to carry these simulations to full amplitude in order to compare them with observed light and velocity curves. Previous 2D calculations were prevented from doing this because of drift in the radial coordinate system, due to the algorithm defining radial movement of the coordinate system during the pulsation cycle. We remove this difficulty by defining our coordinate system flow algorithm to require that the mass in a spherical shell remain constant throughout the pulsation cycle. We perform adiabatic test calculations to show that large amplitude solutions repeat over more than 150 pulsation periods. We also verify that the computational method conserves the peak kinetic energy per period, as must be true for adiabatic pulsation models.

description: Can Daoism serve as a tool in the criticism of modernity and offer an alternative way of living? This thesis intends to put the ideas in Daoism into dialogue with Frankfurt School scholars to analyze four short stories of a contemporary writer Chen Chuncheng 陳春成. In his first collection of short stories published in 2020, Chen juxtaposes a realistic world with a mystic cosmos through natural objects and the practice of crafts. This juxtaposition invokes both Frankfurt School’s criticism of the modern society and a Daoist worldview, both of which yearn for corporeal and experiential connections to a cosmos where every being, whether animated or not, is harmonically integrated into a grand course of the world. Relentlessly writing about the practice of a craft in various socio-historical settings and literary styles, Chen re-writes this motif that links Zhuang Zi’s allegorical tales with Walter Benjamin’s interpretation of the storytelling tradition. He situates this premodern practice in a modern setting to interrogate the efficacy of human language and communicability of experience, comparing the temporality of human society and that of nature.

description: We have investigated the influence of Ca ions substitution on the structural and superconducting properties of (Nd1-xCax)(Ba1.6La0.4)Cu3Oz system. Magnetization, X-ray diffraction and neutron diffraction studies have been carried out on a series of compounds with x = 0.0 to 0.6. The superconducting transition temperature Tc, determined from magnetization measurements increases with increasing Ca2+ substitution. Neutron diffraction studies reveal that these compounds crystallize in a tetragonal structure (space group P4/mmm). A detailed analysis of the neutron diffraction data reveals that Ca and La ions are intermixed at the nominal Ba and Nd sites. While a major fraction of Ca ions occupy the usual Nd site, a small fraction occupies the Ba site. Consequently, the corresponding amount of La substitutes at the nominal Nd site. The intermixing of Ca and La sites randomizes the chain site oxygens leading to a tetragonal structure despite an oxygen content close to 7.0 for all the Ca doped samples. Further increase of Ca content lead to change in its co-ordination from six-fold to eight-fold at x >= 0.4.

Legitimacy judgements in business incubators

Publisher: name: No Publisher Supplied
Year: 2019

description: Based on the importance of resources to entrepreneurial ventures and the predominant role of legitimacy theory in explaining resource supports, this dissertation research explores the mechanism of resource decisions with a perceptual model of legitimacy judgment process. The model was then applied to business incubators, where the screening of new ventures plays a critical role under high uncertainties and in need of better theorization.In study 1, a qualitative analysis with archival information and interviews revealed that opportunity characteristics and entrepreneur characteristics are the two major components of new venture legitimacy in incubator contexts. Study 2 with 170 incubator managers tested the legitimacy judgment model with a vignette study for their effectiveness in explaining judgments formation and resource decisions in business incubators. Results of the vignette study supported the positive effects of both project novelty and team credibility on incubator managers’ legitimacy judgments, and the positive relationships between legitimacy judgments and managers’ resource decisions. The study also confirmed that both CLJ and ELJ’s mediate the effects of venture characteristics on incubator resource decisions. Study 2 did not support the moderation role of team credibility for the mediated relationships between project novelty and resource decisions. However, the between-group comparison analysis suggested that the composition of venture qualities is one critical factor for new venture legitimacy. This research addressed the complexity of social dynamics in business incubators and directed further attention to specific contextual factors and individual-level processes (Bergek & Norrman, 2008; Phan et al., 2005). Business incubation context also supplied a ground for examining different objectives and outcomes of legitimation and revealing the interactive dynamics of legitimacy judgment process.

description: In order to obtain modulated-martensite in our epitaxial Ni-Mn-Ga films, we have tuned the composition by using a co-sputtering process. Here we present how the composition affects the variant distribution of the 14-modulated martensite at room temperature. The nature of such modulated-martensites is still strongly debated for magnetic shape memory alloys. It has been very recently demonstrated that the modulated-martensites in Ni-Mn-Ga are adaptive phases. The results presented here corroborate this theory for the first time, for three different compositions. Moreover, we demonstrate with the help of the adaptive modulations theory that b-variants of the 14-modulated martensite form close to the free-surface of the film to release the stress induced by branching of macro-twinned domains during the martensitic transformation on a rigid substrate. At room temperature, the content of such b-variants is found to strongly decrease when the macro-twinned domain sizes increase.
Exploring postsecondary students' use of proofreading services at a Canadian university
Creators: name: Conrad, Nina Lee
Publisher: name: University of British Columbia
Year: 2018

description: Many postsecondary students engage the services of a proofreader at some stage in their academic career. Such third-party interventions in the production of student texts, classified as a form of literacy brokering (Lillis & Curry, 2010), have raised questions of ethics and academic integrity. In recent years, researchers have begun to examine students’ use of proofreading services from multiple perspectives; however, much of the previous research has focused on graduate students’ dissertations and writing for publication (e.g., Li & Flowerdew, 2007; Turner, 2012), whereas less attention has been paid to other genres of student writing or proofreading practices among undergraduates, and the North American context has rarely been considered. In addition, there is little empirical evidence to support the assumption that proofreading is practiced predominantly by non-native English speakers. This mixed methods study was carried out based on the theoretical framework of academic literacies, a social practice approach to the study of literacy, particularly writing, in academic contexts (Barton & Hamilton, 2000; Lea & Street, 1998). The use of proofreading among students at a large Canadian research university was investigated through an online student survey and follow-up interviews. The aims of the study were to determine who uses proofreading services and to explore their reasons for doing so, the nature and extent of proofreading they receive, and how they perceive this practice to affect their development of language and writing skills as well as other outcomes. The findings suggest that students who use proofreading are diverse and do not conform to any binary categorization. Although there were some differences between self-identified native English speakers and non-native English speakers with respect to their learning outcomes and relationship with their proofreaders, most participants across both groups used proofreading to improve their writing skills and reported learning from the proofreader’s corrections. In addition, use of proofreading has potential to affect writers’ identity and relationships with others in their academic communities. The findings of this research study have implications for writing instruction at every level of postsecondary education and reveal the need for clearer policies on proofreading of all genres of academic writing.

description: Consistent supercurrent multiplets are naturally associated with linearized off-shell supergravity models. In arXiv:1002.4932 we presented the hierarchy of such supercurrents which correspond to all the models for linearized 4D N = 1 supergravity classified a few years ago. Here we analyze the correspondence between the most general supercurrent given in arXiv:1002.4932 and the one obtained eight years ago in hep-th/0110131 using the superfield Noether procedure. We apply the Noether procedure to the general N = 1 supersymmetric nonlinear sigma-model and show that it naturally leads to the so-called S-multiplet, revitalized in arXiv:1002.2228.

Temperature shift

description: This deliverable (D8.2) summarizes the calcination tests conducted within work package 8 (WP8) of CEMCAP project. The main objective was to perform reference air and oxyfuel calcination tests, to evaluate a possible shift of calcination temperature in a CO2-rich oxyfuel environment. The oxyfuel tests were further extended to evaluate the most industrially relevant operational parameters like temperature, residence time and atmosphere. The test results show the average shift of 50-70 K for oxyfuel calcination, which is in line with studies publically available. Provided the higher temperature, reference calcination level (≥90 %) could be achieved within existing suspension calciner conditions. For the test conducted with fuel addition, the reference calcination level (≥90%) for air case was achieved at temperature of 860°C (similar to the temperature reported for industrial calciner), while for oxyfuel case the temperature level up to 940°C was required to achieve similar level of calcination.

The evident problem of amplified formation of deposits at higher temperatures in the calciner could not be linked to increase sintering of raw meal itself. From that point of view retrofitting of existing calciners to oxyfuel operation seems possible. However, to clarify the deposit issue, there should be invested some effort to investigate the influence of ashes derived from burning (alternative) calciner fuel at oxyfuel calcination temperature. Further research and development work should be focused on pilot scale trials in real calciner (hardware) configurations and modeling studies for retrofitting options.

Functional Colors: The Varied Applications of Complementary Hues

Subjects: Film
Color

description: Film scholars in recent years have identified a differentiated landscape of color systems in terms of looks and processes that represent natural color phenomena with increasing fidelity and automation. Here, I propose extending the concept of film colors to techniques that deploy colors in order to produce effects that do not showcolor but useit for other means. Stereoscopy and compositing are two applications from the 1920s that employed complementary colors and that were often developed by the same parties that helped create representational color systems. These correlations have, thus far, not been the subject of color studies because research is organized according to the intended applications of techniques and does not follow the work of the technicians and artists. I argue that techniques that use colors for other purposes have been ignored due to a focus on color primarily in relation to human perception and understanding. To extend the scope of research to nonrepresentational applications of color, as I propose, thus implies a methodological critique of the existing discourse on color as being anthropocentric, that is, as ignoring functional relationships of colors that do not relate to humans.

description: Proxima Centauri (Cen) has been the subject of many flaring studies due to its proximity and potential to host habitable planets. The discovery of millimeter flares from this M dwarf with ALMA has opened a new window into the flaring process and the space-weather environments of exoplanets like Proxima b. Using a total of ~50 hours of ALMA observations of Proxima Cen at 1.3 mm (233 GHz), we add a new piece to the stellar flaring picture and report the first cumulative flare frequency distribution (FFD) at millimeter wavelengths of any M dwarf. We detect 463 flares ranging from energies 10$^{24}$ erg to 10$^{27}$ erg. The brightest and most energetic flare in our sample reached a flux density of 119 $\pm$ 7 mJy, increasing by a factor of 1000x the quiescent flux, and reaching an energy of 10$^{27}$ erg in the ALMA bandpass, with t$_{1/2}$~16s. From a log-log linear regression fit to the FFD, we obtain a power law index of $α_\mathrm{FFD}$ = 2.92 $\pm$ 0.02, much steeper than $α_\mathrm{FFD}$ values (~2) observed at X-ray to optical wavelengths. If millimeter flare rates are predictive of flare rates at extreme-UV wavelengths, the contribution of small flares to the radiation environment of Proxima b may be much higher than expected based on the shallower power-law slopes observed at optical wavelengths.

description: Italian National Committee for Food Safety (CNSA) opinion of 11 MAY 2021 on Unregulated mycotoxins: Ochratoxin A in cheeses and pork products Ochratoxin A (OTA) is of particular health relevance, as it has marked toxic properties, including carcinogenicity with a potential genotoxic mechanism, and is very widespread in food products. Plant-based foods are the main sources of OTA in the diet; however, it is also present in foods of animal origin, especially in pork products and dairy products, mainly related to the surface proliferation of toxicogenic fungi during the ripening nd storage phases. On the basis of the available data, the theoretical level of Italian consumer exposure deriving from the consumption of raw ham and cheeses was calculated. Based on EFSA toxicological reference values, the estimated exposure levels provide MOEs of less than 10,000 for neoplastic effects with a genotoxic mechanism. In particular the results indicate a health concern for children and for high consumers of ham and cheeses. In addition OTA is a highly widespread mycotoxin in food products, whereas the theoretical exposure data reported here relate only to separate consumption of raw ham and cheeses. Consequently, the calculated MOEs do not concern the total daily intake of OTA, to which plant foods are also expected to contribute significantly. To protect consumer health, OTA contamination should be prevented and reduced. Good practices should be adopted in the ripening and storage of cheeses and cured meats. Furthermore, it is important to inform the consumer to avoid the consumption of cheeses and cured meats that have potentially toxigenic molds and that it is not sufficient to remove only the moldy parts, as the mycotoxin can migrate in depth.
