Managing safety and health matters require comprehensive policy intervention to change the existing culture in the ground handling operations and reducing the safety performance outcomes. This study aims to investigate the relationship between safety culture and safety performance outcome with voluntary policy intervention as the moderating effect of the relationship. The study employed a quantitative method through a survey instrument, which was participated by 423 ground handling workers from six international airports in Malaysia. The results indicated seven hypotheses in direct relationships have positive association between safety culture and safety performance construct. While for moderator relationships, there were five hypotheses found to be statistically significant and supported. The presence of voluntary policy interventions were found to be beneficial or detrimental elements for the insignificant relationships of the study. The ground handling organisation is expected to utilise these results by strengthening their organisation safety culture and prioritise safety and health matters over demand and cost. 相似文献

AbstractThe present study investigates how the most foundational factors to individual differences – personality traits and personal values – affect the perceived safety of genetic modification and their relative importance. Publicly available communication data from 522 Twitter accounts discussing genetically modified foods and their safety was processed in two steps. First, accounts were categorized by the researchers as viewing GM foods as either safe or not safe. Second, using the IBM Watson platform, the Twitter communication data were subjected to lexical analysis to assign scores according to the Five Factor Model for personality traits and Schwartz’s basic individual values to the individual accounts. Logistic regression analyses were performed to determine how perceived GM food safety is linked to personality traits and individual values. Although both traits and values significantly contribute to explaining GM attitudes, personality traits strongly moderate the effect of individual values on risk perception. 相似文献

The determinants of migration have been widely studied but research has rarely addressed the roles of food insecurity and gender in the migration decision process. To address these gaps, we examine these relationships for 135,078 individuals across 94 low- and middle-income countries. We use a series of binary-choice models with sample selection and data from the 2014–2015 waves of the Gallup World Poll Survey, which includes the first global measure of individual-level food insecurity. Results, which are robust, indicate that food insecurity is an important determinant of both migration intentions and preparations, and the probability of migration intentions increase monotonically with the severity of food insecurity, and the probability of migration preparations decrease. These relationships also differ significantly by gender and level of gross national income. Evidence suggests a need for increased coordination between the international food security and migration policy agendas. 相似文献

A critical but overlooked issue in Weick’s seminal work, The Social Psychology of Organizing (1969/1979), concerns ‘the heat’ of organizing processes, namely, the underground emotional processes underpinning the organizing of conflictual work relationships. We present a qualitative case study of psychiatric agencies mandated by public policy to collaborate but instead engaged in persistent conflict despite its deleterious effects on their working relationship and on the wellbeing of the clients they intended to serve. To explain these conflictual features of organizing, we integrate Weick’s organizing theory with systems psychodynamics to deepen the understanding of emotions in organizing, specifically the motivational forces underpinning sensemaking and actions between interacting psychiatric agencies. This integration of theories reveals a critical feature of the relationship between the conscious and unconscious organizing processes: When a threat is involved, sensemaking and action are overtaken by social defences, resulting in dysfunctional organizing of the primary task. Drawing on these findings, we enrich Weick’s seminal work by developing a model that portrays organizing as the ritualized interaction of emotions, sensemaking and behavioural responses. 相似文献

Using narrative policy analysis we examined the adversarial rhetoric of claims-makers in their bid to undermine alternative and conflicting accounts of GMOs as environmental and human health risk and to forestall any challenges to the scientific authority of the technological deterministic account of the GMO policy debates in Ghana. The study shows that the GMO discourse was built with the rhetorical frames of smallholder farmer vulnerability and entitlement used in the account it contradicts, thereby legitimating its own appeal for responsive remedies. Civil society claims attacked GMOs as discriminatory and as an environmental and human health risk. Government and scientists engaged in unsympathetic counter rhetorical strategies in hopes of debunking or neutralizing the claim made by civil society. In other words, Government and scientists were denying the claim that GMO was discriminatory and posed significant human health risk, as well as the call to action to do something about GMOs. Civil society adapted the counter rhetoric of insincerity, claiming that scientists had some kind of “hidden agenda” behind their claim, such as eagerness to just earn money from their patents on GMOs. It is imperative that communication on GMOs includes the underlying assumptions, the uncertainties and the probabilities associated with both best and worst case scenarios. This is a necessary condition to minimise misinformation on GMOs but may be insufficient to completely erase conspiracy theories from the minds of the public especially when scientists and government are perceived to be biased towards multinational corporations that are ostensibly preoccupied with making profits. 相似文献

浅析影响食品饮料中糖分检测的因素 总被引:1,自引:0,他引:1
糖类是食品饮料中的重要组成部分。糖类物质是食品工业的主要原料和辅助材料。食品饮料中的糖分的高低不仅影响产品的口感、风味,而且会影响到产品的保质期。因此,食品生产企业必须严格控制食品饮料中的糖分的高低并且能够有效地检测出它的含量。本文从食品饮料中糖分的检测方法出发,主要论述了食品饮料中微量糖分检测的技术要领及其检验中的关键步骤,以实用性强,检测结果准确可靠为宗旨。特别是对于加工低糖、"无糖"食品及干型、半干型葡萄酒、黄酒、果酒的企业来说,提供一种检测技术以指导企业的生产。 相似文献

Cross-cultural consumer behavior is of market interest due to globalization of marketplaces, migration, multicultural marketplaces, and diffusion in the EU of many languages. The objective of this study is to check whether the local language used in a marketing communication could affect the consumers’ preferences for food products. The theoretical foundation is the consumer motivational approach that goes deeper into motivations interfering with the consumers’ preference order. The multivariate conjoint analysis is used to evaluate the preferences for attributes described in different languages. A number of students from the University of Udine (located in the northeastern part of Italy) have been submitted to interviews to examine their preferences for a simulated sandwich package reporting information in different languages, distributed by vendor machine. The results suggest that the consumer’s reaction to local language depends on sociodemographic profile, cultural background, language knowledge, and family education, and the local language could actually be used as a market tool for market segmentation. These results are of interest to many EU countries with bilingual communities such as Spain, Belgium, the UK, Switzerland, and most of the Italian regions where local languages are still alive. 相似文献
