Event detection has long been troubled by the trigger curse: overfitting the trigger will harm the generalization ability while underfitting it will hurt the detection performance. This problem is even more severe in few-shot scenario. In this paper,
we identify and solve the trigger curse problem in few-shot event detection (FSED) from a causal view. By formulating FSED with a structural causal model (SCM), we found that the trigger is a confounder of the context and the result, which makes previous FSED methods much easier to overfit triggers. To resolve this problem, we propose to intervene on the context via backdoor adjustment during training. Experiments show that our method significantly improves the FSED on both ACE05 and MAVEN datasets.
mouthwashes are considered as an essential mean of
oral hygiene. But, due to the side effects of its chemical ingredients
the search for a natural alternative has begun. Honey is one of these
alternatives and has been long known for its antimicrob
ial
properties.
This study aims to evaluate the efficacy of Syrian honey
mouthwash on oral flora in comparison with Chlorhexidine 0.12%
This study has been conducted on Syrian coastal area in 2013 season, aimed to
determines affecting factors on honey supply at that level Apiary and measure the price
supply elasticity . A field questioner was applied to obtain elementary data of a
random
sample consisted of (304) of Apiary.
The honey production has been estimated to (10.3) kg/hive and (603.8) kg/ apiary in
the study sample, (89.6%) of which were marketed, while the other part has been selfconsumed
at the apiary level. The marketing quantities of honey distributed between five
major marketing canals, the most important one was the direct selling to the consumers,
contributed to (77.1%) of total sample’ marketed quantities, followed by the selling to
wholesalers with contribution ratio estimated to (18.7%), while the selling to retailer types
(Honey specialized shops, Pharmacies, Grocers) have absorbed the remained small honey
quantities.
The supply price elasticity was estimated to (2.318), referring relatively to a high
elasticity supply. The more diversified marketing channels of honey at apiaries level has
positively affected supply quantities, especially when selling to wholesalers. Moreover, the
existence of selling and storing unites in apiaries in addition to the market information
system would also affect positively on supply quantities. The positively effect of apiary
size reflects the weak position of small size apiaries in supply controlling.
The more important result, was the negative impact of expertize and specialization
and education of producers on honey supplied quantities at apiaries level, Remunerating
Precarious conditions of current honey market, pressing on producers belonging to the
qualified category and indicates high risks of shrinking their leverage in honey sub-sector.
This study has been conducted on Syrian coastal area in 2013 season, aimed to
analyze the cost of honey production and Farm income `at the Apiaries level, in addition to
measure its net returns and economic efficiency. A field questioner was applie
d to obtain
elementary data of a random sample consisted of (304) of Apiary units.
The results show that beekeeping is one of the economically viable agricultural
projects, where most of the apiaries in the sample were able to achieve a positive net return
as much, on average, about (405 834) SP / promiscuous, while its value was estimated at
the hive level by about (7120) SP. It was found that the majority of apiaries in the study
sample (87.8%) were able to achieve positive earnings, While the ratio (12.2%) exposed of
the loss, and realized negative revenues .
The results of the investment evaluation and financial analysis showed to the
economic efficiency of the apiaries , reaching gross margin of the hive (11237.5) SP/year,
and ratio of costs to revenue (62.9%), the profit ratio to total costs (59%), and general
economic efficiency (1.59 ), and the Payback period (1.69) years.
The concentrations of copper (Cu), zinc (Zn), nickel (Ni), lead (Pb),
cadmium (Cd) in dead and live honeybees were determined by using
atomic absorption spectrophotometry. The samples were collected from
beehives of stationary apiariessituated in
five different locations of
Latakia; Qardahah (Asitamo), Haffeh (Dabba), Jableh (Snouper),Latakia
city (Al-Ramel Al-Shamali\ Autostrade of Al-Jomhouria) and Eastern
Entryway to Latakia (behind Al-Jood factory) , during the spring and
autumn in 2014.
In this study it has been determined the total phenols percentage of
three Syrian honey types. Then the relation has been studied
between phenols level in these three types of Syrian honey and its
effect on the Escherichia coli which causes many t
ypes of intestinal
and uric infections and causes many diseases as bleeding.
This study was conducted in the Syrian coastal region, and the honey samples have
been collected from eight different sites belonging to the provinces of Latakia and Tartous
during the autumn of 2012. Their content of heavy metals (zinc, copper, le
ad & cadmium)
was estimated by Atomic Absorption at the Higher Institute for Environmental Research at
Tishreen University. The results showed that zinc concentration in the bee honey samples
ranged from 2.86 to 12.64 mg / kg (mean 7.98±3.67), and copper ranged from 0.125 to
0.652 mg / kg (mean 0.328±0.176 ), lead ranged from 0.084 to 0.378 mg / kg (mean
0.205±0.112), cadmium ranged from 0.0002 to 0.0132 mg / kg (mean 0.0053±0.0052). The
results indicated that the largest amounts of heavy metals were found in honey sample
taken from the apiary which is located at the eastern entrance of Latakia city (near Joud
factory), while the lower concentrations of zinc and lead were in Banias area (Wadi Al
Saqi), and the least concentration of copper was in Safita area, and of cadmium was in the
Gablah area (Bani Qahtan Castle).Comparing elements concentration in the studied honey
samples, Zinc concentration was found to be the highest, followed by copper, lead and then
finally cadmium.The results of statistical analysis indicated the existence of significant
differences between the studied sites during the autumn of 2012.
This research aims to study the dimensions of honey harvesting in the poetry of Al-
Huthaliyeen who associate talking about honey harvesting by comparing the sweet taste of
honey to a woman's saliva taste. Thus , they demonstrate the pleasure of ac
hieving the
desiredgoalafter toil. In this context , we see them highlight the mixing of honey with pure
water and wine to signify the sublime life they seek to attain. In their poetry , we see them
explore the poor living conditions of the apiarist - his toil and experiencing dangers to get
honey. They explain that in his quest of honey under difficult conditions like the rugged
place , the apiarist offers an image of a poet who strives to accomplish his goal. The
dangers of getting honey are highlighted in Al- Huthaliyeenpoetry. Such dangers increase
the hardships of reaching the goal in which the prerequisites and permanence of life are
represented.
This study was conducted in the spring of 1999 in Al-Souida Region of
Syria, to know the effect of flower pollination by honeybees on flower and fruitset
and on the crop productivity of three varieties of apple. The experiment was
repeated in the
spring of 2001 on the same varieties in addition to others like
Yellow sport, but the weather conditions (spring-frost) didn’t allow to obtain
results.
Floral honey types produced locally were tested for their quality attributes,
using the standard procedures of the Association of the Official Analytical
Chemists (AOAC).
