格尔木井地下流体主测项数据可靠性分析

本文介绍了格尔木井的基本情况及所架数字仪器的技术系统构成，对水位、地热、气氡等主测项2003年1月1日-2004年12月31日的数字化资料进行了初步分析，发现地热数据基本稳定；气氡数据由原集气装置的不合理，数据上下波动较大，基本无法使用，经改造后，数据趋于稳定；水位受到调节集气装置出水量的影响，但排除该影响后数据基本可以使用。

Sustainable three‐well pumping strategy for efficient detection monitoring near waste impoundments

Efficient monitoring systems addressing the difficulty of detecting narrow contaminant plumes originating from unknown point sources are needed for modern landfills. A low‐discharge extraction and accompanying injection wells could potentially address this problem. This hypothetical computer‐modeling study involved a three‐well detection system consisting of one extraction and two injection wells at a rectangular landfill in a shallow, unconfined aquifer. The extraction and injection wells were located near the landfill's downgradient and cross‐gradient corners, respectively. Each injection well pumped at half the rate of the extraction well. A minimum pumping rate of 1.1 cubic meters per day was determined for the three‐well system; at this rate, all contaminant plumes originating within the landfill's footprint entered the extraction well prior to reaching a downgradient property boundary. In comparison, five passive (not pumped) wells detected all contaminant releases from the landfill. Results of this study suggest that a low‐discharge extraction well with accompanying injection wells may be an effective contaminant detection strategy at some waste impoundments.     

You want me to do what? Two daily diary studies of illegitimate tasks and employee well‐being

Illegitimate tasks, a recently introduced occupational stressor, are tasks that violate norms about what an employee can reasonably be expected to do. Because they are considered a threat to one's professional identity, we expected that the daily experience of illegitimate tasks would be linked to a drop in self‐esteem and to impaired well‐being. We report results of two daily diary studies, one in which 57 Swiss employees were assessed twice/day and one in which 90 Americans were assessed three times/day. Both studies showed that illegitimate tasks were associated with lowered state self‐esteem. Study 1 demonstrated that high trait self‐esteem mitigated that relationship. Study 2 showed that illegitimate tasks were associated with not only lowered state self‐esteem but also lower job satisfaction and higher anger and depressive mood, but not anger or job satisfaction remained elevated until the following morning.

桂南地下热水系统中氟的分布及迁移富集规律

选取广西桂南地区地下热水系统为研究对象,利用氢氧同位素及锶同位素研究手段,对研究区内地下热水中氟的空间分布规律及其控制因素进行研究。结果表明:研究区内地下热水中氟含量变化范围为0.01~17.93mg/L,其中43%地下水样品中氟含量超过饮用水氟骨症临界值1.5mg/L,高氟地下热水的主要水化学类型为Na-HCO3型,水体中氟含量与温度呈明显正相关性;地下热水氢氧同位素特征显示,研究区地下热水的主要来源为大气降水,同时受一定程度蒸发浓缩及水-岩作用影响,地下热水锶同位素特征显示,研究区地下热水水化学组成明显受长石、云母等铝硅酸盐风化及碳酸盐岩溶解影响;对地下热水水化学开展的因子分析结果显示,研究区地下热水系统中影响氟迁移释放的主要因素为萤石的溶解与沉淀过程。     

Using self‐determination theory to understand the relationship between calling enactment and daily well‐being

This paper contributes to the calling literature by using self‐determination theory—a theory that makes distinctions between different types of motivation—in order to gain a better understanding of how enacting a calling may relate both positively and negatively to well‐being. We use a daily diary method novel to the calling field and a sample with a distinctive calling, Church of England clergy. We expect daily calling enactment to relate positively to daily well‐being via more autonomous forms of motivation (intrinsic and identified motivation) and negatively via less autonomous forms (introjected motivation). Furthermore, we consider how the relationship between calling enactment and motivation may be moderated by perceived competence. The hypotheses were tested using multi‐level structural equation modeling. There was strong support for calling enactment relating positively to well‐being, and this relationship was fully mediated by intrinsic and identified motivation; the hypothesized negative pathway, from calling enactment, to introjected motivation, to well‐being, was not supported. However, perceived competence was found to moderate some of the relationships between calling and the motivation types, where calling enactment is linked to lower introjected motivation at high levels of competence.
