Attractiveness Of Work Research Articles

Current situation of attraction and retention of doctors working at Tien Giang central general hospital in period 2016-2018 and some influenced factors

The study was conducted with 02 objectives to describe and analyze some factors affecting the attraction and retention of doctors working at Tien Giang Central General Hospital. The research design is cross-sectional, combining literature review and qualitative methods. It was conducted from January to July 2019. Literature review was used to find out situation of health worker attraction and retention while qualitative research was implemented with health workers and managers to find influencing factors. Research results show that the hospital lacks doctors to serve the overloaded number of patients: the ratio of doctors/ beds is only 0.18 (194/1.100). For 03 years (from 2016 to 2018), the hospital recruited 46 doctors, compared with the staffing needs is 107 doctors, reaching 43% as planned. The number of doctors who quit their jobs in these 3 years was 21 people, of which 04 doctors quit their jobs due to family situations. Some factors affecting the attraction and retentions of doctors at the hospital are recruitment, attraction policies, recognition of achievements, working environment, training opportunities and income. The research results provide evidence to help the Board of Directors to develop solutions to attract and retain doctors in the future. Keywords: attraction, retention, doctor, factor, hospital.

Influence of queen weight and colony origin on worker response in Solenopsis geminata

. The influence of weight and colony origin of the queen of Solenopsis geminata (F.) (Hymenoptera: Formicidae) on worker attraction is studied under laboratory conditions. In the first experiment, worker response to individual queens of different weight from the same colony is evaluated. Heavier queens are more attractive than smaller queens to their own workers. In subsequent experiments, the colony origin effect is investigated and worker response to a pair of queens of the same weight from the same or different colonies is compared. When queens are from the same colony, workers do not show a significant preference between queens. However, when queens are from a different colony, workers are significantly more attracted to their own queen than to the foreign queen. Finally, the response of workers to queens of different weight from the same or different colonies is investigated. In both cases, workers are significantly more attracted to a heavier queen than a lighter queen, even if the lighter queen is their own queen. A putative pheromonal component (E)-6-(1-pentenyl)-2H-2-pyranone, is not positively correlated with queen weight.

Elimination of sexual brood in the Argentine ant Linepithema humile: queen effect and brood recognition

AbstractMated queens of the ant Linepithema humile (Iridomyrmex humilis Mayr) introduced into dequeened colony fragments rearing sexual brood elicited worker aggression resulting in queen larvae being bitten and eliminated. By contrast, male larvae were spared. Regarding queen brood, killing mainly concerned small and medium sized larvae. A large proportion of the large larvae escaped extermination, and prepupae and pupae were spared. These data suggest that workers were able to discriminate sex, caste and age of the brood.That a queen pheromone may be involved was shown by experiments using whole or cut corpses that were either rinsed or not rinsed in pentane. The pheromone eliciting worker aggressive behaviour was shown to act over a short distance, suggesting that it is somewhat volatile. Similarities and differences between this new queen pheromone and other known queen pheromones acting on queen production or worker attraction are discussed as well as the origin of the signals underlying the recognition of the larval classes.

Ontogeny of queen attraction to workers in the antCataglyphis cursor (Hymenoptera: Formicidae)

The behaviour ofCataglyphis cursor workers towards queens at 15 days, one month or two months after worker emergence was tested. Workers reared entirely with their own maternal queen were tested with this queen or with an unfamiliar alien queen. Workers transferred within 48 h of emerging to a new definitive nest with an alien queen were tested with this queen or with the original maternal queen. The degree of attraction to each of these queens and the workers' behavioural repertoire were measured and analysed. The results showed the following: 1) The attractiveness of queens and the workers' queen recognition behaviour were linked. 2) Although unfamiliar alien queens hardly attract workers, familiar alien queens were as attractive as maternal queens, and induced the same strongly marked and unique worker response, indicating that workers learn queen attractant cues in the days immediately after emergence. 3) Agonistic reactions were observed, but workers continued to be attracted to their maternal queen even after developing an attraction response to an alien queen with which they had been reared. These results agree with the proposal that queens produce two kinds of pheromones, those that attract workers and those that mediate recognition of queens by workers. These results show the ability of workers to discriminate between queens. Workers are attracted to any queen, but recognize as nestmates only maternal or alien queens with which they have been maintained. 4) The differential in worker attraction and recognition from 15 days to 2 months and its modifications by post-imaginal experience illustrate worker behavioural ontogeny, which is a basis of social discrimination.

Colony behavior of the obligate social parasiteVespula austriaca (Panzer) (Hymenoptera: Vespidae)

The obligate social parasite,Vespula austriaca (Panzer), after successfully usurping a colony, displayed overt physical dominance of the host workers,V. acadica (Sladen). Agonistic inquiline behavior such as mauling, chasing workers, and flailing were commonly observed during observations of 5 parasitized colonies. The parasites solicited workers more frequently than larvae for liquid nourishment, and commonly engaged in both typical and forced trophallaxis. Aggressiveness of the parasite was more intense during the early stages of colony occupation, and was less frequent and vigorous in the later stages of the colony. A brief, and probably intense, oviposition period occurred during the period of heightened parasite aggression. This species exhibited many activities similar to those of another vespine inquiline,Dolichovespula arctica (Rohwer), such as hyperactivity, gastral dragging, minimal nest construction and lack of colony defense, but also displayed some contrasting interactions. There was an absence of worker attraction to the inquiline, an inhibition of worker ovarian development by the parasite, and decreased aggression in later colony stages. It is hypothesized thatV. austriaca maintains colony control through an interplay of direct and forceful interactions with workers and by the use of pheromones.
