Saying thanks and meaning it: Expressing gratitude for social gain.

People sometimes give thanks as a true expression of their feeling but also sometimes because they know gratitude expression helps to make a certain social impression. That is, some gratitude is expressed because of intrinsic motivations or extrinsic motivations. Such motivations affect the outcomes of behaviour. The present work assessed gratitude, trait tendency to manage socially desirable expressions and well-being across two studies (combined n = 398). Motivations to express gratitude were also measured and impression management goals were manipulated in Study 2. Results show that gratitude expression is highest when people want to make a good impression and extrinsic motives to express gratitude can moderate the relationship between gratitude and well-being. Implications for the measurement of gratitude and theoretical understanding of gratitude's social function are discussed.

More than fantasy: Prosocial daydreams relate to prosocial dispositions and behaviour.

The current studies examined the relationship between the penchant to daydream about helping others and prosocial traits and behaviour. We reasoned that fantasising about prosocial acts should be positively associated with a more prosocial disposition and real behaviour. Across both studies, the findings suggest that people who exhibit prosocial characteristics (e.g., empathic concern, fantasy/fictional empathy, moral reasoning) are more likely to fantasise about prosocial behaviour, and these characteristics are reliably associated with increased helping behaviours. From Study 1, the correlational results showed that people higher in agreeableness exhibited a stronger tendency to engage in prosocial fantasising, and empathy, in part, mediated the relationship. The experimental results from Study 2 conceptually support those from Study 1; when prompted to fantasise about prosocial behaviour, those higher in agreeableness and openness to experience engaged in more helping behaviour, whereas in a control condition, no helping differences emerged. Finding that empathic concern was most consistently related to daydreaming is consistent with the theory in that people are more intrinsically motivated to promote other's welfare at a personal cost when they feel empathy. Engaging in prosocial fantasising may increase empathy, which in turn, may enhance one's prosocial disposition and increase one's helping behaviour.

Meeting report of the OECD conference on "Genome Editing: Applications in Agriculture-Implications for Health, Environment and Regulation".

The "OECD Conference on Genome Editing: Applications in Agriculture-Implications for Health, Environment and Regulation" was held on the 28-29 June 2018 at the OECD headquarter and conference centre in Paris, France. It brought together policy makers, academia, innovators and other stakeholders involved in the topic, in order to take stock of the current technical developments and implementations of genome editing, as well as their applications in various areas of agriculture and the implications they give rise to (More information on the "OECD Conference on Genome Editing: Applications in Agriculture-Implications for Health, Environment and Regulation" can be found on the OECD Genome Editing hub: http://www.oecd.org/environment/genome-editing-agriculture/ ; the hub also contains the detailed conference programme, the biographies of all conference speakers, the detailed conference abstracts, and the presentations of the two-day conference). The conference aimed to provide a clearer understanding of the regulatory considerations raised by products of genome editing, pointing towards a coherent policy approach to facilitate innovations involving genome editing.

Developing OECD test guidelines for regulatory testing of nanomaterials to ensure mutual acceptance of test data.

The OECD Working Party on Manufactured Nanomaterials (WPMN) provides a global forum for discussion of nano-safety issues. Together with the OECD Test Guidelines Programme (TGP) the WPMN has explored the need for adaptation of some of the existing OECD Test Guidelines (TGs) and Guidance Documents (GDs) as well as developing new TGs and GDs to specifically address NM issues. An overview is provided of progress in the TGP and WPMN, and information on supporting initiatives, regarding the development of TGs for nanomaterials addressing Physical Chemical Properties, Effects on Biotic Systems, Environmental Fate and Behaviour, and Health Effects. Three TGs specifically addressing manufactured nanomaterials have been adopted: a new TG318 ″Dispersion Stability of Nanomaterials in Simulated Environmental Media", and adaptation of TG412 and TG413 on Subacute Inhalation Toxicity: 28-Day Study/90-day Study. The associated GD39 on Inhalation Toxicity Testing has also been revised. The TGP current develops four new TGs and four GDs. One new TG and six GDs are developed in the WPMN. Six new proposals were submitted to the TGP in 2018. Furthermore, as TGs are accompanied by OECD harmonised templates (OHTs) for data collection, an outline of recently developed OHTs particularly relevant for NMs is also included.

Nanomaterials: certain aspects of application, risk assessment and risk communication.

Development and market introduction of new nanomaterials trigger the need for an adequate risk assessment of such products alongside suitable risk communication measures. Current application of classical and new nanomaterials is analyzed in context of regulatory requirements and standardization for chemicals, food and consumer products. The challenges of nanomaterial characterization as the main bottleneck of risk assessment and regulation are presented. In some areas, e.g., quantification of nanomaterials within complex matrices, the establishment and adaptation of analytical techniques such as laser ablation inductively coupled plasma mass spectrometry and others are potentially suited to meet the requirements. As an example, we here provide an approach for the reliable characterization of human exposure to nanomaterials resulting from food packaging. Furthermore, results of nanomaterial toxicity and ecotoxicity testing are discussed, with concluding key criteria such as solubility and fiber rigidity as important parameters to be considered in material development and regulation. Although an analysis of the public opinion has revealed a distinguished rating depending on the particular field of application, a rather positive perception of nanotechnology could be ascertained for the German public in general. An improvement of material characterization in both toxicological testing as well as end-product control was concluded as being the main obstacle to ensure not only safe use of materials, but also wide acceptance of this and any novel technology in the general public.

Physico-chemical properties of manufactured nanomaterials - Characterisation and relevant methods. An outlook based on the OECD Testing Programme.

Identifying and characterising nanomaterials require additional information on physico-chemical properties and test methods, compared to chemicals in general. Furthermore, regulatory decisions for chemicals are usually based upon certain toxicological properties, and these effects may not be equivalent to those for nanomaterials. However, regulatory agencies lack an authoritative decision framework for nanomaterials that links the relevance of certain physico-chemical endpoints to toxicological effects. This paper investigates various physico-chemical endpoints and available test methods that could be used to produce such a decision framework for nanomaterials. It presents an overview of regulatory relevance and methods used for testing fifteen proposed physico-chemical properties of eleven nanomaterials in the OECD Working Party on Manufactured Nanomaterials' Testing Programme, complemented with methods from literature, and assesses the methods' adequacy and applications limits. Most endpoints are of regulatory relevance, though the specific parameters depend on the nanomaterial and type of assessment. Size (distribution) is the common characteristic of all nanomaterials and is decisive information for classifying a material as a nanomaterial. Shape is an important particle descriptor. The octanol-water partitioning coefficient is undefined for particulate nanomaterials. Methods, including sample preparation, need to be further standardised, and some new methods are needed. The current work of OECD's Test Guidelines Programme regarding physico-chemical properties is highlighted.

Review of achievements of the OECD Working Party on Manufactured Nanomaterials' Testing and Assessment Programme. From exploratory testing to test guidelines.

This paper charts the almost ten years of history of OECD's work on nanosafety, during which the programme of the OECD on the Testing and Assessment of Manufactured Nanomaterials covered the testing of eleven nanomaterials for about 59 end-points addressing physical-chemical properties, mammalian and environmental toxicity, environmental fate and material safety. An overview of the materials tested, the test methods applied and the discussions regarding the applicability of the OECD test guidelines, which are recognised methods for regulatory testing of chemicals, are given. The results indicate that many existing OECD test guidelines are suitable for nanomaterials and consequently, hazard data collected using such guidelines will fall under OECD's system of Mutual Acceptance of Data (MAD) which is a legally binding instrument to facilitate the international acceptance of information for the regulatory safety assessment of chemicals. At the same time, some OECD test guidelines and guidance documents need to be adapted to address nanomaterials while new test guidelines and guidance documents may be needed to address endpoints that are more relevant to nanomaterials. This paper presents examples of areas where test guidelines or guidance for nanomaterials are under development.

The risk/safety assessment of transgenic crops: the transportability of data.

This paper presents the activities and publications of Organisation for Economic Co-operation and Developments (OECD's) Working Group on Harmonisation of Regulatory Oversight in Biotechnology and the Task Force for the Safety of Novel Foods and Feeds. The main outputs of the work are the Series of "consensus documents" of the respective groups. These documents compile information which is intended to be used by those involved in the business of risk/safety assessment. These documents are one means of ensuring the transportability of data amongst authorities. An increasing trend in both the Working Group and Task Force is to consider crop species which are relevant to tropical regions and therefore to countries that are not necessarily members of the OECD. For example, the Working Group has recently published a consensus document on bananas and plantains while the Task Force has published a document on cassava. This trend towards crops of greater interest in the tropics is likely to continue into the future.

Reactions to a remote-controlled video-communication robot in seniors' homes: a pilot study of feasibility and acceptance.

OBJECTIVE: Remote telepresence provided by tele-operated robotics represents a new means for obtaining important health information, improving older adults' social and daily functioning and providing peace of mind to family members and caregivers who live remotely. In this study we tested the feasibility of use and acceptance of a remotely controlled robot with video-communication capability in independently living, cognitively intact older adults. MATERIALS AND METHODS: A mobile remotely controlled robot with video-communication ability was placed in the homes of eight seniors. The attitudes and preferences of these volunteers and those of family or friends who communicated with them remotely via the device were assessed through survey instruments. RESULTS: Overall experiences were consistently positive, with the exception of one user who subsequently progressed to a diagnosis of mild cognitive impairment. Responses from our participants indicated that in general they appreciated the potential of this technology to enhance their physical health and well-being, social connectedness, and ability to live independently at home. Remote users, who were friends or adult children of the participants, were more likely to test the mobility features and had several suggestions for additional useful applications. CONCLUSIONS: Results from the present study showed that a small sample of independently living, cognitively intact older adults and their remote collaterals responded positively to a remote controlled robot with video-communication capabilities. Research is needed to further explore the feasibility and acceptance of this type of technology with a variety of patients and their care contacts.

Regulatory and Policy Considerations Around Genome Editing in Agriculture.

The increasingly widespread use of genome editing brought with it a fierce debate about the most adequate regulation of this latest innovation in modern biotechnology and the products resulting from it. In almost all cases, this debate has become a repetition or continuation of the deliberations concerning genetically modified organisms (GMOs) of the 1990s and early 2000s.This chapter aims to untangle the historically influenced and often biased arguments of the debates by addressing the complex question of the correct interpretation of relevant underlying law and its applicability. In doing so, the chapter considers 25 countries and regions that have published results or ongoing investigations and discussions pertaining to the governance of genome editing in their jurisdictions: 16 have published policies or signed statements that exempt gene edited plants from GMO-regulations, as long as no foreign DNA or transgene remained in the final product. Such exemptions are based on the widely supported acceptance that the products of the underlying genome editing processes resemble those of "conventional breeding" techniques. These policies and statements often refer to the important role that modern precision biotechnologies, of which genome editing is one, play in addressing some of the world's overarching challenges, such as the loss of biodiversity, pest and disease control, and climate change; they are furthermore shown to exhibit an adherence to the four universal principles of good regulation: (a) proportionality, (b) non-discrimination, (c) predictability, and (d) enforceability. And while it is the right of jurisdictions to develop their own regulations independent from that of their neighbors, it is specifically the principle of "enforceability" that may become the ultimate litmus test of those regulations that do not grant exemptions from GMO-regulations.

Biotechnology and Biosafety Policy at OECD: Future Trends.

The OECD Council Recommendation on Recombinant DNA Safety Considerations is a legal instrument which has been in force since 1986. It outlines the safety assessment practices that countries should have in place for agricultural and environmental biotechnology. This article suggests possible updates to make it suitable for the modern era.

Policy Considerations Regarding Genome Editing.

The international Organisation for Economic and Co-operative Development (OECD) conference on genome editing (June 2018) provided a timely platform for scientists, risk assessors, policy-makers, and regulators to discuss the applications and implications of this technology in various agriculture areas and the related policy considerations; in addition questions related to appropriate safety assessments and the regulation of genome-edited products were debated.

Air-Liquid Interface In Vitro Models for Respiratory Toxicology Research: Consensus Workshop and Recommendations.

In vitro air-liquid interface (ALI) cell culture models can potentially be used to assess inhalation toxicology endpoints and are usually considered, in terms of relevancy, between classic (i.e., submerged) in vitro models and animal-based models. In some situations that need to be clearly defined, ALI methods may represent a complement or an alternative option to in vivo experimentations or classic in vitro methods. However, it is clear that many different approaches exist and that only very limited validation studies have been carried out to date. This means comparison of data from different methods is difficult and available methods are currently not suitable for use in regulatory assessments. This is despite inhalation toxicology being a priority area for many governmental organizations. In this setting, a 1-day workshop on ALI in vitro models for respiratory toxicology research was organized in Paris in March 2016 to assess the situation and to discuss what might be possible in terms of validation studies. The workshop was attended by major parties in Europe and brought together more than 60 representatives from various academic, commercial, and regulatory organizations. Following plenary, oral, and poster presentations, an expert panel was convened to lead a discussion on possible approaches to validation studies for ALI inhalation models. A series of recommendations were made and the outcomes of the workshop are reported.

Ageing and Learning in Australia: Arguing an Evidence Base for Informed and Equitable Policy.

BACKGROUND: Given Australia's population ageing and predicted impacts related to health, productivity, equity and enhancing quality of life outcomes for senior Australians, lifelong learning has been identified as a pathway for addressing the risks associated with an ageing population. To date Australian governments have paid little attention to addressing these needs and thus, there is an urgent need for policy development for lifelong learning as a national priority. The purpose of this article is to explore the current lifelong learning context in Australia and to propose a set of factors that are most likely to impact learning in later years. CONCLUSION: Evidence based policy that understands and incorporates learning opportunities for all citizens is required to meet emerging global challenges. Providing appropriate learning opportunities to seniors is one clear pathway for achieving diverse health, social and economic outcomes.
