Conducting fit‐for‐purpose food safety risk assessments

Abstract The interplay between science, risk assessment and risk management has always been complex, and even more so in a world increasingly characterised by rapid technical innovation, new modes of communication, suspicion about authorities and experts, and demands for people to have a say in decisions that are made on their behalf. In this challenging era where scientific advice on food safety has never been in greater demand, risk managers should effectively navigate the interplay between facts and values and be able to rely on robust and fit‐for‐purpose risk assessments to aid them. The fact that societal resistance is often encountered when scientific advice on food safety operates at a distance from social values and fails to actively engage with citizens, has led to increasing emphasis on the need to advance forms of risk assessment that are more contextual, and socially sound and accountable. EFSA's third Scientific Conference explored how risk assessments could be constructed to most usefully meet society's needs and thus connect science with society, while remaining scientifically robust. Contributors to the conference highlighted the need to: (1) frame risk assessments by clear policy goals and decision‐making criteria; (2) begin risk assessments with an explicit problem formulation to identify relevant information; (3) make use of reliable risk assessment studies; (4) be explicit about value judgements; (5) address and communicate scientific uncertainty; (6) follow trustworthy processes; (7) publish the evidence and data, and report the way in which they are used in a transparent manner; (8) ensure effective communication throughout the risk analysis process; (9) involve society, as appropriate; and (10) weigh risks and benefits on request. Implementation of these recommendations would contribute to increased credibility and trustworthiness of food safety risk assessments.
ANALYSIS OF AN ANTI-PARALLEL MEMRISTOR CIRCUIT

The basic purpose of the present paper is to propose an extended investigation and computer analysis of an anti-parallel memristor circuit with two equivalent memristor elements with different initial values of the state variables using a modified Boundary Condition Memristor (BCM) Model and the finite differences method. The memristor circuit is investigated for sinusoidal supply current at different magnitudes – for soft-switching and hard-switching modes, respectively. The influence of the initial values of the state variables on the circuit’s behaviour is presented as well. The equivalent i-v and memristance-flux and the other important relationshipsof the memristor circuit are also analyzed.
Hiding query access patterns in range queries using private information retrieval and oblivious ram

This work addresses the problem of hiding query access patterns in privacypreserving range queries while guaranteeing data and query con dentiality. We propose two methods, which are based on Private Information Retrieval (PIR) and Oblivious RAM (ORAM) techniques, respectively. For the PIR based search operation, we introduce a new scheme based on Lipmaa's computationally-private information retrieval (CPIR) method. We reduce the computation cost of CPIR by reducing the number of modular exponentiation operations, employing shallow trees and utilizing multi-exponentiation techniques. Furthermore, we improved the performance of CPIR by applying parallel algorithms. For the ORAM based method, we adapted Stefanov's Path ORAM method to the privacy-preserving range search. Our analyses show that, in terms of communication cost, CPIR provides better bandwidth usage especially in large database sizes, while in computational cost, Path ORAM based method performs better due to the negligible cost of server operations. The results imply that, despite some advantageous qualitative aspects of CPIR and its highly parallel implementation, it is still an expensive scheme in terms of computation complexity in comparison with Path ORAM for hiding query access patterns in privacy preserving range queries.
A Two-Stage Cascaded Multi-Level Inverter

The cascaded H-bridge multi-level inverter has been extensively applied to middle-high voltage and high power fields, but it has disadvantages of numerous DC voltage sources and switch tubes. Based on this reason, this paper presents a two stage cascaded multilevel inverter. The preceding stage is composed of several basic modules through cascading, and the backward stage is H-bridge inverter. The direct voltage use ratio of every basic module in this inverter is increased by 2 times, and the number of DC voltage sources and switch tubes is reduced effectively. In addition, H-bridge at the backward stage operates under power frequency conditions only, which can further reduce the switching loss. According to the new type of inverter, this paper proposes carrier cascading modulation and hysteresis control method combining. The cascaded multilevel inverter can output a variety of level. Finally, simulation model of the inverter is built up, the input and load jump of the two working modes are simulated and analyzed. The performance of the proposed inverter are verified by simulation.

MATCH BIAS OR NONIGNORABLE NONRESPONSE? IMPROVED IMPUTATION AND ADMINISTRATIVE DATA IN THE CPS ASEC

We test an improved imputation technique, sequential regression multivariate imputation (SRMI), for the Current Population Survey Annual Social and Economic Supplement to address match bias. Furthermore, we augment the model with administrative tax data to test for nonignorable nonresponse. Using data from 2009, 2011, and 2013, we find that the current hot deck imputation used by the Census Bureau produces different distribution statistics, downward for poverty and inequality and upward for median income, relative to the SRMI model-based estimates. Our results suggest that these differences are a result of match bias, not nonignorable nonresponse. Nearly all poverty, median income, and inequality estimates are not significantly different when comparing imputation models with and without administrative data. However, there are clear efficiency gains from using administrative data.
Gaussian processes for machine learning

The main focus of this project is to present clearly and concisely an overview of the main ideas of Gaussian processes for regression in a machine learning context. The introductory chapters contain core material and give some theoretical analysis of how to construct Gaussian processes models, the way to express many types of structure through kernels and how adding and multiplying different kernels combines their properties. Moreover explanatory examples are also covered in order to gain a deeper understanding of the material. Finally we provide an alternative approach from a Machine Learning complex problem carried out by a prestigious European Bank in endeavours to achieve a reliable method to predict customer expenses and consequently to forecast the balance of bank accounts. The aim was to analyze deeply this problem using Gaussian Processes for Regression from two different perspectives. Firstly, all the bank accounts studied as a global entity and then clustering the accounts regarding its similarity allowing a more flexible and adaptive approach.

Traditional African Dishes Prepared From Local Biofortified Varieties of Pearl Millet: Acceptability and Potential Contribution to Iron and Zinc Intakes of Burkinabe Young Children

Biofortification is among the food-based strategies, recently implemented and still in development, to fight micronutrient deficiencies. Three cereal-based traditional dishes of Sub-Saharan Africa (tô paste, pancakes, and gruel) prepared from one local (Gampela), or two biofortified (GB 8735 and Tabi) varieties of millet were assessed for their (i) acceptability by local consumers, (ii) iron and zinc absorption predicted by phytate-to-mineral molar ratios and (iii) contribution to the iron and zinc requirements of young children. Tasters preferred the color, texture, and taste of dishes prepared with the local variety, whether or not the grains were decorticated. Hedonic and preference tests showed no significant difference between the two biofortified varieties, but the cooks reported different behaviors during processing. Biofortified millet contained up to two times more iron than the local variety, reaching 6.5 mg iron/100 g dry matter. Iron and zinc contents remained higher in biofortified varieties even after decortication. Iron content in the dishes was highly variable, depending on iron loss and potential contamination during processing. The phytate-to-mineral molar ratios of all dishes indicated low iron absorption, independent of the millet variety, but improved zinc absorption in dishes prepared with biofortified varieties. The contribution of a dish prepared with one of the two biofortified millet varieties to the recommended iron and zinc intakes for 6–11-month-old children was estimated to be about 5 and 7%, respectively, compared to 2 and 4% for the same dish prepared with local millet. For 12–23-month-old children, the contribution to the recommended intakes was estimated to be about 14 and 12% with biofortified millet, respectively, and about 6 and 7% with local millet. The use of biofortified millet varieties could be complementary to food diversification strategies to increase iron and zinc intakes. As in Ouagadougou, cereals are eaten in different forms by young children several times per day, iron and zinc intakes could be improved in the long term by using the biofortified varieties of pearl millet.
Anatomy, Bony Pelvis and Lower Limb, Tibial Nerve

The tibial nerve is one of the two terminal branches of the sciatic nerve, the largest nerve in the human body. The tibial nerve originates from the L4-S3 spinal nerve roots and provides motor and sensory innervation to most of the posterior leg and foot. In addition to its motor branches, the branches of the tibial nerve include the medial sural cutaneous nerve, medial calcaneal nerve, and the medial and lateral plantar nerves.
WP-AD 2012-06 On Integration Policies and Schooling *

This paper proposes a reform for school allocation procedures in order to help integration policies reach their objective. For this purpose, we suggest the use of a natural two-step mechanism. The (stable) first step is introduced as an adaptation of the deferred-acceptance algorithm designed by Gale and Shapley (1962), when students are divided into two groups. The (efficient) second step captures the idea of exchanging places inherent to Gale’s Top Trading Cycle. This latter step could be useful for Municipal School Boards when implementing some integration policies.
Correction of over-exposure using dark channel prior and image fusion technique

A novel over exposure (OE) correction method using Dark Channel Prior and image fusion technique is proposed in this work. Assuming an OE image can be modeled as a normal exposure image added up with a layer of asymmetrical haze, its submerged information in OE regions is enhanced by haze removal model. With image fusion technique, the obtained texture in OE regions is used to restore the over exposure. Experiments show that our method works well in submerged information restoration without increasing pseudo-information and over Saturation.
Efficacy of Dosages of the Embryonic Stimulant Preparation for Preventing of Postpartum Complications in Cows

The research was aimed at determining the optimal dosage of "STEMB" (Embryonic Stimulant) for preventing delivery and postnatal complications, for which purpose 4 groups of 20 cows in each were formed. During the experiment, the animals in the studied groups were in similar feeding and keeping conditions, dry matter in the diet amounted to 44.95%. The animals in the experimental groups received "STEMB" subcutaneously three times in the 30 days period before delivery with the interval of 7 days in the following dosages: the first experimental group received 0.05 ml per 1 kg of live weight; the second experimental group received 0.075 ml per 1 kg of live weight; the third experimental group received 0.10 ml per 1 kg of live weight; the cows in the reference group did not receive the preparation. It has been determined that the dosage of "STEMB" equal to 0.075 ml per 1 kg of live weight prevents postpartum complications, shortens the labor and the postpartum period. The obtained data may be used for developing the reference criteria of using "STEMB" for correcting the reproductive function and preventing complications during delivery and postnatal complications.
Array Comparative Genomic Hybridization as a Diagnostic Tool in Cancer

The knowledge of the primary origin of tumor is essential in designing an efficient cancer treatment algorithm. Useful diagnostic tools enable determination of primary origin of the tumor; however the majority of them require tissue examination. Recent years, exploration of circulating tumor cells enabled scientists to study different parameters using the painless liquid biopsy. The present study aimed to identify whether aCGH might be used as a diagnostic tool in cancer detecting the primary origin of the tumor. Blood was extracted from healthy individuals and cancer samples and CTCs isolated. DNA extracted from the above samples and aCGH experiments followed. The samples were blinded analyzed and then unmasked to calculate specificity and sensitivity of the method. The sensitivity was 94%, the specificity 88%, while the positive prediction rate of the primary tumor was 72%. aCGH is a powerful tool in cancer diagnosis and treatment plan with high sensitivity and specificity rates. It can be performed from blood sample, which makes it an appropriate method for every patient, mainly for patients with unknown origin of the primary tumor.
Factors Associated to the Non-adherence to Vaccination Appointments in the Ngambe Health District, Littoral Region, Cameroon: A Case Control Study

Background: Vaccination is what is strongly recommended in protecting against childhood diseases. The Expanded Program of Immunization (EPI) in Cameroon started in 1976 as a pilot project and became operational all over the country in 1982 where vaccination is seen a fundamental right of every child in the country. However, rural areas have lots of constrains to the effective implementation of vaccination programs some of which are population-related. Purpose: This study aimed to assess the association between some factors and adherence to vaccination appointments in Ngambe Health District; a typical rural health district in Cameroon. Methods: This was a case control study where the vaccination records of health facilities in the district were reviewed and parents who respected their vaccination appointments formed the controls while those who missed a vaccination appointment were the cases. They were then traced for interviewed and data analyzed using Epi infos version 3.5. 4. Results: Out of 94 parents, 37.2% had missed a vaccination appointment. In parents older than 36, the odds of missing an appointment was 11 (95%CI 3.69-34.43) while those with <4 children were 0.10 less likely to miss an appointment (95%CI 0.04-0.28). Parent’s education, household size and ANC attendance also influenced adherence to vaccination appointments. After adjustment, only age and whether or not child was born in the hospital remained statistically significant associated with adherence. Conclusion: User related factors influence uptake of vaccination services in the Ngambe Health District of Cameroon; a rural area, some of which are age of the parents, number of children the parent has and the total household size. Therefore, adding to the availability of vaccines, a high-level political commitment aimed at increasing utilization of health services and effectively taking vaccination to the population are indispensable.
Auditory P300 in Elderly with Sensorineural Hearing Loss

Background: Hearing loss and cognitive impairment are common problems in older adults; several studies were conducted on the effects of hearing aid use relative to cognitive function in older adults. Most studies only used a verbal questionnaire which could lead to biased results. Therefore, the auditory P300 response from an electrophysiologic test provides an objective measure of central auditory function, including the cognitive process in the brain. Methodology: A cross-sectional study was conducted from July, 2016 to April, 2017 at The Hearing Aid Clinic in Ramathibodi Hospital. Participants were 26 elderly patients with bilateral symmetrical sensorineural hearing loss who were referred for unilateral hearing aid fitting by ENT doctors. The auditory P300 test results and MMSE-Thai scores were recorded before and 2 months after hearing aid fitting. Results: The P300 waveforms could be recorded from only 21 participants with a mean latency of 374.48 ms and mean amplitude of 6.68 μV. Two months after hearing aids were used, the mean P3 latency was 376.83 ms and the mean amplitude was 8.77 μV. There was a statistically significant difference in the amplitudes of P3 2 months after HA fitting (p=0.004). Moreover, the MMSE-Thai scores were also significantly higher (p=0.000). Conclusion: The auditory P300 components could be recorded from approximately 80% of the sensorineural hearing loss elderly patients in this study. The auditory P300 results showed an improvement in cognitive ability with higher amplitude, corresponding to an increase in MMSE-Thai scores. Thus, the P300 may be used to evaluate the improvement in cognitive function after using a hearing aid. This outcome can be a guideline in counseling patients who initially rejected hearing aids on the benefits of using the hearing aids.
THE EFFECTS OF A MODIFIED FIFA 11+ WARM-UP PROTOCOL ON FITNESS VARIABLES IN MIDDLE SCHOOL STUDENTS

Introduction: Lower extremity injuries, specifically anterior cruciate ligament (ACL) injuries are prevalent in adolescent sports. The FIFA 11+ injury-prevention program has been shown to decrease lower extremity injuries in several sports settings. There is limited literature regarding the effects of the FIFA 11+ on fitness variables, especially among middle school students. The purpose of this study was to retrospectively evaluate if a modified FIFA 11+ warm-up protocol has any effect on cardiovascular endurance, muscular endurance, and flexibility at two Vermont middle schools with different physical education class schedules. Materials and Methods: Outcome data was obtained from the FitnessGram assessment, which is utilized by all Vermont middle schools to track trends in youth fitness levels. The effects of the modified warm-up protocol on cardiovascular endurance (PACER test), muscular endurance (curl-up test), and flexibility (sit-and-reach) at Williston Central School (WCS) were compared to age-matched non-intervention year FitnessGram data at WCS and to intervention year FitnessGram data at Shelburne Community School (SCS). Results: Statistical analysis for WCS comparing data from the non-intervention and intervention years demonstrated a significant decrease in PACER score (p Discussion: The results of this study indicate that utilization of a prolonged injury-prevention warm-up program in lieu of organized physical education activities traditionally completed during physical education classes at these middle schools may have a deleterious effect on some fitness-related outcomes. It is important to note that this is a small, retrospective investigation and is hypothesis-generating; however, a larger-scale randomized controlled trial should be performed to validate these findings. This information may be used to alter the modified FIFA 11+ warm-up protocol to be effective in both injury prevention and improving fitness among middle schoolers.
