Analysis of Consumer Preferences for Quality and Safety Attributes in Artisanal Fruit Juices in Kenya

This study used choice experiment survey data from a random sample of 374 respondents to analyze consumer preferences for quality and safety attributes of artisanal fruit juices in Kenya. Results show that consumers had a positive and significant preference for single fruit juices compared to fruit mixtures, private rather than public inspection of the juices, traceability of fruit origin, and vendor’s health. Additives such as colorants, flavors, and preservatives were not preferred. Consumers were willing to pay premiums of up to 200% for artisanal juices that contain single fruits, lack additives, and are inspected by private agencies. These insights should be incorporated in ensuring that artisanal fruit juice designs comply with food quality and safety requirements. Further, there is a need to license and regulate the artisanal juice preparation and handling and to provide training to the handlers on safety and quality requirements.     

Adoption of food safety measures on milk production in Nepal: Impact on smallholders’ farm-gate prices and profitability

One way to ensure food safety is by enhancing compliance at the farm level. This study investigates the status, estimates the cost, identifies the determinants, and assesses the impact of compliance with food safety measures (FSM) in milk production in Nepal. The study is based on primary data collected from six high milk producing districts that captures the geographical and institutional diversity of milk production. Results show that the status of farm level compliance with FSM is not very encouraging. Also, the intensity of adoption of FSM exhibits significant inter- and intra-district variations. It varies positively with herd size but the additional cost of compliance with FSM varies negatively with herd size. Among other determinants, access to information, and incidence of inspection for conformity with safety and quality standards are also associated with higher adoption of FSM. Finally, we also estimate the impact of FSM on farm-gate prices and farmers’ profits and conduct several robustness checks.     

Risk analysis of the EASA minimum fuel requirements considering the ACARE-defined safety target

We present the results of flight simulator experiments (60 runs) with randomly selected airline pilots under realistic operational conditions and discuss them in light of current fuel regulations and potential fuel starvation. The experiments were conducted to assess flight crew performance in handling complex technical malfunctions including decision-making in fourth-generation jet aircraft. Our analysis shows that the current fuel requirements of the European Aviation Safety Agency (EASA) are not sufficient to guarantee the safety target of the Advisory Council for Aviation Research and Innovation in Europe (ACARE), which is less than one accident in 10 million flights. To comply with this safety target, we recommend increasing the Final Reserve Fuel from 30 min to 45 min for jet aircraft. The minimum dispatched fuel upon landing should be at least 1 h.

Dose safety motivation mediate the effect of psychological contract of safety on flight attendants' safety performance outcomes?: A social exchange perspective

This study proposes and tests a conceptual model that investigates the mediating effect of safety motivation linking psychological contract of safety (PCS) as manifested by employer obligations of safety and employee obligations of safety to safety violations and safety creative performance (SCP). Data were collected from a sample of flight attendants with two weeks time lag in Iran. Underpinned by social exchange theory, the results of structural equation modeling revealed that safety motivation fully mediates the simultaneous effects of PCS indicators on safety violations and SCP. Specifically, indicators of PCS jointly enhance safety motivation. In turn, safety motivation reduces safety violations, while enhancing SCP. Theoretical and practical implications evoked from the results advance existing knowledge of organizationally social interactions in promoting safety and the motivational mechanism through which PCS predicts employees' safety performance outcomes.     

Fluctuating levels of personal role engagement within the working day: A multilevel study

In this diary study, we examined a theoretical model in which the psychological conditions of meaningfulness, availability, and safety serve as mechanisms through which the work context during discrete situations within the workday influences “state” engagement. We further theorised that a person's “trait” level of engagement would exert cross‐level effects on the state level relationships. Multilevel analyses based on a sample of 124 individuals in six organisations and 1,446 situational observations revealed that meaningfulness and availability (but not safety) mediated the relationships between perceptions of the work context and state engagement. High levels of trait engagement strengthened the within‐person relation between availability and state engagement, yet weakened the within‐person relation between meaningfulness and state engagement, suggesting two different processes may be at play. Overall, the findings advance our understanding of engagement as a multilevel and temporally dynamic psychological phenomenon and promote a contextually based HRM approach to facilitating engagement.     

建国初期中共粮食战略与1949年云南公粮征收研究

1950年3月6日以宋任穷为书记的中共云南省委正式成立，3月12日即颁布命令征收1949年公粮。当时各地基层政权立足未稳，难以承担如此巨任，阶级矛盾、民族矛盾错综复杂，征粮刚一展开即受挫。其原因主要一是云南财政恶化超出预想，粮食存量少；二是粮食新政权的保障，所以中共云南省委不遗余力地大力推进征粮工作。此次征粮不仅与云南地方军民生活用度有关，更与建国初期中共新政权在经济战场上与敌人斗争紧密相连。
