The dataset covers seven Chinese products over the period 1992–2008. We find that standards have a positive effect on China's export performance, as the benefits to standardization in terms of reducing potential information asymmetry and signaling enhance food safety, and quality in foreign markets seem to surpass compliance costs. Our estimation results show that the positive effect of Chinese standards is larger when they are harmonized to international measures. The results suggest that there are clear benefits to China's steps to base their domestic standards and regulations on international measures

Increasing Seed Viability of Maize Haploid Inducing Lines by Genetic and Non-Genetic Approaches

Some haploid inducing lines used in the production of maize doubled haploids (DHs), express germination problems and reduced vigor. In this study, haploid inducing lines RWS, RWK-76 and their reciprocal hybrids RWS/RWK-76 and RWK-76/RWS were examined for viability by Tetrazolium (TZ) and germination ability by standard germination tests. Evaluation based on TZ tests showed that 59% of the seed of RWK-76/RWS were not viable, compared with only 12% dead seed in RWS/RWK-76. Similarly, the percentage and speed of germination in RWK- 76/RWS (25%, 1.53) was lower than for RWS/RWK-76 (74%, 4.30). In an effort to develop a quick method for assessing seed viability in these lines, the TZ test was repeated in a different way. Seed from each genotype was placed in beakers containing distilled water.Seed would either float or sink. Subsequent TZ testing confirmed that seed that floated was dead, and seed that sank was alive, although some of them had defective embryos. The dead seed in both genotypes failed to develop an embryo, leaving an empty cavity that would fill with air and cause seed to float on water. This feature can be exploited for a simple and practical method to separate living from dead seed. In addition, we surveyed theig1 (indeterminate gametophyte) gene as a candidate for germination problems in inducer lines.Sequencing data from theig1 region showed that RWS and RWK-76 differed in one nucleotide and amino acidin the firstexon of ig1.Segregation of ig1 alleles from RWS and RWK-76 wassignificantly (P=0.01) distortedin the respectiveF2 population relative to the expected Mendelian segregation ratio (1:2:1). Thus, either ig1 or a linked gene in the ig1 region affect seed viability

The latent structure of the adult attachment interview: Large sample evidence from the collaboration on attachment transmission synthesis

The Adult Attachment Interview (AAI) is a widely used measure in developmental science that assesses adults’ current states of mind regarding early attachment-related experiences with their primary caregivers. The standard system for coding the AAI recommends classifying individuals categorically as having an autonomous, dismissing, preoccupied, or unresolved attachment state of mind. However, previous factor and taxometric analyses suggest that: (a) adults’ attachment states of mind are captured by two weakly correlated factors reflecting adults’ dismissing and preoccupied states of mind and (b) individual differences on these factors are continuously rather than categorically distributed. The current study revisited these suggestions about the latent structure of AAI scales by leveraging individual participant data from 40 studies (N = 3,218), with a particular focus on the controversial observation from prior factor analytic work that indicators of preoccupied states of mind and indicators of unresolved states of mind about loss and trauma loaded on a common factor. Confirmatory factor analyses indicated that: (a) a 2-factor model with weakly correlated dismissing and preoccupied factors and (b) a 3-factor model that further distinguished unresolved from preoccupied states of mind were both compatible with the data. The preoccupied and unresolved factors in the 3-factor model were highly correlated. Taxometric analyses suggested that individual differences in dismissing, preoccupied, and unresolved states of mind were more consistent with a continuous than a categorical model. The importance of additional tests of predictive validity of the various models is emphasized

Bifidobacterium animalis subsp. lactis Bi-07 contributes to increasing lactose digestion: evaluation of a health claim pursuant to Article 13(5) of Regulation (EC) No 1924/2006

Following an application from DuPont Nutrition Biosciences ApS submitted for authorisation of a health claim pursuant to Article 13(5) of Regulation (EC) No 1924/2006 via the Competent Authority of Ireland, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on the scientific substantiation of a health claim related to Bifidobacterium animalis subsp. lactis Bi-07 (Bi-07) and contribution to increasing lactose digestion. The scope of the application was proposed to fall under a health claim based on newly developed scientific evidence. The food proposed by the applicant as the subject of the health claim is Bi-07. The Panel considers that Bi-07 is sufficiently characterised. The claimed effect proposed by the applicant is \u2018improvement of lactose digestion\u2019. The Panel considers that increasing lactose digestion is a beneficial physiological effect for individuals with lactose maldigestion provided that the symptoms of lactose maldigestion are improved. Two human intervention studies which investigated a single dose effect of Bi-07 on lactose digestion using the hydrogen breath test, as well as on gastrointestinal symptoms were submitted. These studies show that consumption of Bi-07 (1012 CFU) increases lactose digestion in individuals with lactose maldigestion and that Bi-07 exhibits lactase activity in vitro. However, these studies provide no evidence that increasing lactose digestion through the consumption of Bi-07 (1012 CFU) improves gastrointestinal symptoms of lactose maldigestion, which is considered a beneficial physiological effect. The Panel concludes that a cause and effect relationship has not been established between the consumption of Bifidobacterium animalis subsp. lactis Bi-07 and a beneficial physiological effect (i.e. the improvement of symptoms of lactose maldigestion) in individuals with lactose maldigestion

Parental beliefs, infant temperament, and marital quality: Associations with infant–mother and infant–father attachment.

The present research examined parental beliefs about the importance of the paternal caregiving role, mothers’ and fathers’ reports of infant temperament, and observed marital quality as predictors of infant-mother and infant-father attachment security, over and above the effects of parental sensitivity. Infants’ attachment security to mothers and fathers were observed in the Strange Situation at 12- and 13-months, respectively (N = 62 two-parent families). Hierarchical regression models revealed that mothers who viewed the paternal caregiving role as important were less likely to have securely attached infants, but only when infant fussiness was high. Additionally, fathers who viewed the paternal caregiving role as important were more likely to have securely attached infants, but only when infants’ fussiness or marital quality was high

Re-evaluation of behenic acid from mustard seeds to be used in the manufacturing of certain emulsifiers pursuant to Article 21(2) of Regulation (EU) No 1169/2011 – for permanent exemption from labelling

Following a request from the European Commission, the Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to review a scientific assessment related to a notification from DuPont Nutrition Biosciences Aps on behenic acid from mustard seeds to be used in the manufacturing of certain emulsifiers pursuant to Article 21(2) of Regulation (EU) No 1169/2011 – for permanent exemption from labelling. The EC requested EFSA to consider comments raised by the German authorities in relation to: (a) the maximum amount of mustard protein that could be consumed from the emulsifiers manufactured from behenic acid (E470a, E471 and E477) on a single occasion and (b) the minimal observed eliciting dose (MOED) triggering allergic reactions in mustard-allergic individuals. The maximum amount of mustard protein content in behenic acid was re-assessed in view of new analytical data provided by the applicant. Intake estimates by the EFSA ANS Panel for E471 (adults) were used as a proxy for the combined intake (E470a, E471 and E477). Food challenge data and systematic reviews thereof deriving population minimal observed eliciting dose distributions for mustard protein were used to calculate the MOED and estimate the risk. The margin of exposure between the MOED (0.26 mg mustard protein) and the maximum amount of mustard protein that could be consumed from the emulsifiers on a single occasion (0.00895475 mg) is 29. It is predicted that between 0.1% and 1% of the mustard allergic population would react with mild objective symptoms to that dose. Overall, the assessment is conservative, particularly in relation to the exposure. Based on the information and data available, the NDA Panel concludes that it is extremely unlikely (≤ 1% probability) that oral consumption of emulsifiers to be manufactured using behenic acid from mustard seeds (i.e. E470a, E471 and E477) will trigger an allergic reaction in mustard-allergic individuals under the proposed conditions of use

Scientific Opinion related to a notification from Lyckeby Starch AB on barley starch to be used in the manufacturing of several foods as ingredient, of the food additive modified starch and of glucose syrups pursuant to Article 21(2) of Regulation (EU) No 1169/2011 – for permanent exemption from labelling

Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver a scientific opinion on barley starch to be used in the manufacturing of several foods as ingredient, of the food additive modified starch and of glucose syrups pursuant to Article 21(2) of Regulation (EU) No 1169/2011, as notified by Lyckeby Starch AB. The applicant provided information on the manufacturing process and data on the content of total protein, gluten and allergenic proteins in barley starch. The applicant also performed IgE-binding in vitro tests, which were considered inconclusive by the Panel. No human intervention studies with barley starch or food products thereof were provided by the applicant, except for a DBPCFC with barley starch hydrolysate in cereal allergic individuals. The Panel notes that glucose syrups based on barley have been already exempted from allergen labelling as per Annex II of Regulation (EU) No 1169/2011 and that the current application is for the exemption from labelling of all foods manufactured from barley starch. In all the scenarios considered for the anticipated intake, the calculated total protein intake from barley starch was above the MED/MOED for wheat (expressed in mg of wheat protein) in adults (10 mg) and children (2 mg). The Panel concludes that the data available are insufficient to conclude on the likelihood of adverse allergic reactions in cereal-allergic individuals upon consumption of barley starch under the conditions of use proposed by the applicant, and that the consumption of foodstuffs produced from barley starch as starting (raw) material or foodstuffs containing barley starch as an ingredient is unlikely to cause an adverse reaction in individuals with coeliac disease who are not allergic to cereals, provided that the value of gluten for ‘gluten-free’ foods (20 mg/kg) is not exceeded

Appethyl® and reduction of body weight: evaluation of a health claim pursuant to Article 13(5) of Regulation (EC) No 1924/2006

Following an application from Greenleaf Medical AB, submitted for authorisation of a health claim pursuant to Article 13(5) of Regulation (EC) No 1924/2006 via the Competent Authority of Sweden, the EFSA Panel on Nutrition, Novel Foods and Food allergens (NDA) was asked to deliver an opinion on the scientific substantiation of a health claim related to Appethyl® and reduction of body weight. Appethyl® is an aqueous extract from spinach leaves standardised by the manufacturing process and its lipase/colipase inhibition capacity in vitro. The Panel considers that the food is sufficiently characterised. A reduction in body weight is a beneficial physiological effect for overweight/obese individuals. The applicant identified a total of three human intervention studies that investigated the effects of Appethyl® on body weight as being pertinent to the claim. In weighing the evidence, the Panel took into account that Appethyl® (5 g/day for 12 weeks) had no effect on body weight as compared to placebo under minimal dietary counselling and moderate physical activity, and that no beneficial physiological effects are to be expected for the target population of overweight/obese individuals from the weight loss that could be attributed to the intervention with Appethyl® under predefined energy restriction and moderate physical activity. The Panel also considered that the effect of Appethyl® (5 g/day for 24 weeks) on body weight maintenance after initial weight loss shown in one study has not been replicated in different settings, which questions the external validity of the results, and that no evidence was provided for a plausible mechanism by which daily consumption of Appethyl® could exert a sustained effect on body weight in humans. The Panel concludes that a cause-and-effect relationship has not been established between the consumption of Appethyl® and a reduction of body weight under the conditions of use proposed by the applicant
