Being constantly connected to others via e‐mail and other online messages is increasingly typical for many employees. In this paper, we develop and test a model that specifies how interruptions by online messages relate to negative and positive affect. We hypothesize that perceived interruptions by online messages predict state negative affect via time pressure and that perceived interruptions predict state positive affect via responsiveness to these online messages and perceived task accomplishment. A daily survey study with 174 employees (a total of 811 day‐level observations) provided support for our hypotheses at the between‐person and within‐person level. In addition, perceived interruptions showed a negative direct association with perceived task accomplishment. Our study highlights the importance of being responsive to online messages and shows that addressing only the negative effects of perceived interruptions does not suffice to understand the full impact of interruptions by online messages in modern jobs. 相似文献

The construction industry is an important sector of the economy in Poland. According to the National Labour Inspectorate (PIP) data of 2014, the number of victims of fatal accidents in the construction sector amounted to 80 as compared with 187 injured in all other sectors of economy in Poland. This article presents the results of surveys on the impact of construction worker behaviour on the occupational safety and health outcomes. The surveys took into account the point of view of both construction site management (tactical level) and construction workers (operational level). For the analysis of results, the method of numerical taxonomy and Pareto charts was employed, which allowed the authors to identify the areas of occupational safety and health at both an operational and a tactical level, in which improvement actions needed to be proposed for workers employed in micro, small, medium and large construction enterprises. 相似文献

After the Great East Japan Earthquake in March 2011, numerous evacuees had to stay in evacuation shelters such as school gymnasiums. In general, after a disaster, ensuring the safety and security of evacuees in evacuation shelters is a serious problem. Consequently, many of these evacuees feared that they would be victims of crime in the shelters or that their evacuated homes would be burgled. To examine what factors evoke a general fear of crime in shelters and burglary of evacuated homes, we conducted an online questionnaire on 300 evacuees in Miyagi Prefecture who had stayed at such shelters. From a factor analysis of fear of 16 specific kinds of crime in shelters, we extracted two factors representing fear of property and female-related crime. We then found that a general fear of crime in shelters was associated with being young and a fear of female-related crime, while a fear of burglary of evacuated homes was associated with being female, owning a detached house, and fear of property crime. Based on these results, we provide recommendations aiming to help reduce the fear of crime in shelters and burglary of evacuated homes. 相似文献

运用遥感技术,对粤北地区尾矿库进行调查发现,粤北地区尾矿库主要包括金属矿山、非金属矿山、选冶场所尾矿库,安全隐患较多,环境污染较为突出,地质灾害风险明显,二次矿山资源浪费较为严重。近年来,广东省及各市县等地方政府部门加强了对粤北地区尾矿库的管理,取得了一定的成效,未来应进一步加强监管和治理力度,提高尾矿资源利用水平。 相似文献

Exxon Neftegas Limited, as operator of the Sakhalin-1 consortium, is developing oil and gas reserves on the continental shelf
off northeast Sakhalin Island, Russia. DalMorNefteGeofizika (DMNG) on behalf of the Sakhalin-1 consortium conducted a 3-D
seismic survey of the Odoptu license area during 17 August–9 September 2001. A portion of the primary feeding area of the
endangered western gray whale (Eschrichtius robustus) is located in the vicinity of the seismic survey. This paper presents data to assess whether western gray whale bottom feeding
activity, as indicated by visible mud plumes, was affected by seismic operations. The mitigation and monitoring program associated
with the seismic survey included aerial surveys during 19 July–19 November 2001. These aerial surveys documented the local
and regional distribution, abundance, and bottom feeding activity of western gray whales. Data on gray whale feeding activity
before, during and after the seismic survey were collected, with the whales assumed to be feeding on the benthos if mud plumes
were observed on the surface. The data were used to assess the influence of seismic survey and other factors (including environmental)
on feeding activity of western gray whales. A stepwise multiple regression analysis failed to find a statistically significant
effect (α = 0.05) of the seismic survey on frequency of occurrence of mud plumes of western gray whales used as a proxy to evaluate
bottom feeding activity in Piltun feeding area. The regression indicated that transect number (a proxy for water depth, related
to distance from shore) and swell height (a proxy for sea state) were the only variables that had a significant effect on
frequency of whale mud plumes. It is concluded that the 2001 seismic survey had no measurable effect (α = 0.05) on bottom feeding activity of western gray whales off Sakhalin Island.

Hydric soils are used as supportive evidence for wetland delineations by federal and state agencies and by the private sector
in North Carolina, USA. An analysis of hydric soil distribution and hydric soil characteristics was conducted with county
soil surveys and soil taxonomy of the USA. Approximately 100 hydric soils have been used for soil mapping in North Carolina,
and they represent seven of the ten soil orders in soil taxonomy. An estimated 23% (2.9 million ha) of the land surface area
in North Carolina supports hydric soils.
Approximately 96% of the known hydric soil acreage was found in the coastal plain of North Carolina. Over one-third of the
soils were hydric Ultisols, which represented close to 10% of the land surface area. The other soil orders with extensive
hydric soil acreage included Histosols, Inceptisols, and Entisols. The soil orders were separated into great groups of soil
taxonomy to discuss soil profile characteristics. Landscape positions and associated wetland communities were also presented.
In North Carolina, a statewide inventory of wetlands does not exist and soil surveys offer a resource for a first approximation
of wetland boundaries. 相似文献

中国环境行政执法能力建设现状调查与问题分析 总被引:7,自引:0,他引:7
环境行政执法能力建设正成为中国环境行政管理体制建设的一个重点.中国已建立起一个四级环境执法体系,最新成立的区域环境督查中心标志着中国环境行政执法体制建设又迈出了新的一步.对85个执法机构,162家企业就环境行政执法机构的人力投入、资金支持、技术保障、执法手段、执法产出、执法阻力、社会动员和企业激励8个方面进行了问卷和访谈形式的调查.从省、市、县三级执法角度全面分析了中国环境行政执法各方面存在的问题.研究认为,中国的环境行政执法总体而言已经建立起一个完备的框架,各地对环境执法日益重视,环境行政执法能力得到了提高;但是环境行政执法随着经济发展、公众环境意识的提高面临着越来越大的压力,承担的任务也更为繁重.为了应对挑战,环境法律、体制和各方面的投入以及执法理念都要进一步改进. 相似文献

In this paper, the role played by habitat diversity in the landscape on species richness and on the stability of farmland bird communities was investigated. Species richness was estimated on 374 samples monitored in farmland by the French breeding bird survey during the 2001–2005 period. A capture–recapture approach was used to estimate species richness accounting for the variation in detection probability among species of the 100 most common species detected in farmland. Landscape structure and composition were measured both in farmland and in adjacent habitats. The independent effect of each variable on community richness and stability was further assessed using hierarchical variance partitioning and taking spatial autocorrelation into account. A strong matrix effect was detected: non-cropped land deeply influenced richness and stability of bird assemblages. 相似文献
