Therefore, managers should pay attention to their psychological experience and provide targeted assistance to them.展开更多

Twenty four (24) dogs were enrolled in the study. A first set of 16 dogs were acclimatised to their cages from Day 1 to 7 and a second set of 8 dogs from Day 163 to Day 169. The 24 dogs were randomly allocated to three groups (1 to 3). Dogs assigned to Group 1 were not treated and served as negative controls. Dogs assigned to Group 2 received the Seresto? collar on Day 0 and dogs in Group 3 received Frontline Tri-Act? on Days 170 and 198. The dogs were observed hourly for four hours after treatment administration for possible adverse reactions. Dogs in Groups 1 and 2 underwent water showering on Days 14, 28, 42, 56, 70, 84, 98, 112, 126, 143 and 157. Dogs in all groups underwent water showering on Days 173, 185, 199 and 213. Dogs were infested with approximately 100 (±4) adult, unfed C. felis fleas only on Days 177, 190, 203, and 217, in alternance with infestations with 50 adult unfed R. sanguineus on Days 182, 196, 210, and 224, to assess sustained efficacy. Fleas and ticks were removed and counted on 24 and 48 hours ± 2 hours after each infestation, respectively. Frontline Tri-Act? was >99% effective against C. felis following an initial and a second monthly administration on dogs that were water showered bi-weekly. The Seresto? collar was from 68.3% to 92.9% effective against C. felis Days 178 to 218 after collar administration. Frontline Tri-Act? was effective from 87.8% to 100% against ticks whereas Seresto collar was effective from 82.2% to 94.2% from Day 184 to Day 226.展开更多

Thus understanding their lived experiences provides insights that helps alleviate health worker burnout and improving their quality of life thereby leading to an efficient delivery of health care services during a pandemic. Aim: To understand the lived experiences of front line health workers during the COVID-19 pandemics at Levy Mwanawasa Teaching University Hospital. Design and Methods: A qualitative interpretative phenomenological study design was used. Purposive sampling method was adopted to select the 14 participants who took part in the study. The data were collected through face-to-face, audio-taped interviews using an in-depth interview guide, after which the responses were transcribed verbatim before using NVIVO to generate codes. The data were analyzed using thematic method. Results: The lived experiences of the participants were found to be mainly negative with few positive experiences. Their lived experiences were mainly negative emotional and psychological experiences including fear, anger, depression, frustration, anxiety and sadness. The thoughts that were identified included thoughts of surviving through the pandemic, thoughts of getting infected, and dying. The frontline health workers also experienced some personal and professional changes as they offered health services in the COVID-19 wards. The personal changes reported included;social limitations and collapse of extra income business while the professional changes included a change in the way health services were delivered, a gain in knowledge and skills and shaping of a career path. The main challenges experienced were limited resources (man power, resuscitation equipment, drugs, personal protective equipment), limited literature on the disease and limited social interactions. Conclusion and Recommendations: Relevant stakeholders should come on board in order to offer support during a pandemic or a similar situation so as to better the experience of frontline health workers with particular attention directed towards the provision of adequate resources to enable them deliver their services effectively. Frontline health workers perspectives and opinions should be taken into account by the institution’s administrators and policymakers when planning for and managing a pandemic.展开更多

文摘In cognitive linguistics,debates on the status and functions of categorization have been a heated issue.In semantics and second language acquisition,scholars have discussed and achieved vocabulary acquisition from different perspectives and academic levels.Vocabulary learning exerts a fundamental role in second language vocabulary acquisition(SLVA),and it is closely related to learners’cognitive competence.However,studies on second language vocabulary acquisition under the categorization theory in cognitive linguistics have received less attention from linguists when compared with other studies.This paper employs two representative dimensions,the basic-level effect and the prototype effect,under the categorization theory to further delve into the implications on second language vocabulary acquisition.This article first provides a comprehensive introduction to the nature and the approaches of the categorization theory,and then analyzes the relations and implications for second language vocabulary acquisition under the categorization theory from the perspective of the basic-level and the prototype effects.The research results showed that the basic-level effect on SLVA is mainly on the classification of word categories distinguished from the superordinate and subordinate categories,while the prototype effect is more on understanding the complexity and use of word meaning.
