Objective: past research has shown relationship problems associated with narcissists’ excessive self-centeredness and lacking concern for others. Using romantic relationships as opportunities to self-enhance rather than caring about intimacy, narcissists are sensitive to shortcomings in their partners and quick to withdraw investment once relationships turn out to be less than perfect. Our research aimed to reveal whether narcissists are aware of their destructive relationship behavior or tend to put the blame for a failed relationship on their ex-partners. Conversely, do ex-partners of narcissists take the blame and feel responsible for the breakup or walk away convinced their narcissistic ex-partners’ behavior was just too unbearable? Method: 120 participants (19-59 yrs) who reported a recent romantic breakup completed a battery of questionnaires online, including measures of narcissism and self-esteem, as well as newly created scales assessing attributions for breakup. In addition to self-reports, participants retrospectively rated their ex-partners on adapted versions of the same measures. Results: narcissists made attributions to lacking relationship investment mostly in themselves and to a lesser extent in their partners. However, this pattern was reversed when self-esteem was controlled, with attributions to partner shortcomings outnumbering aspects of own destructive behavior. Narcissism perceived in the ex-partner was related to reports of lacking investment in oneself as well as the ex-partner, but controlling for self-esteem reduced the number of attributions to own shortcomings. Conclusion: our analyses revealed that narcissists do show some awareness of their contribution to a failed relationship, although controlling for self-esteem increased their blame of the ex-partner. In contrast, associations between perceived partner-narcissism and aspects of own lacking relationship investment became fewer when self-esteem was controlled for.

Introduction: According to the American Cancer Society, each day, more than 4,000 teens try cigarettes for the first time, and another 2,000 become daily smokers. One-half of these teens eventually will die from a smoking-related disease. [See PDF for complete abstract]

An experimental short-term acidification with HCl at a first-order stream in central Maine, USA was used to study processes controlling the changes in stream chemistry and to assess the ability of stream substrate to buffer pH. The streambed exerted a strong buffering capacity against pH change by ion exchange during the 6-hour acidification. Streambed substrates had substantial cation and anion exchange capacity in the pH range of 4.1 to 6.5. The ion exchange for cations and SO42- were rapid and reversible. The speed of release of cations from stream substrates was Na1+ > Ca2+ > Mg2+ > Aln+ > Be2+, perhaps relating to charge density of these cations. Ca2+ desorption dominated neutralisation of excess H+ for the first 2 hr. As the reservoir of exchangeable Ca diminished, desorption land possibly dissolution) of Al3+ became the dominant neutralising mechanism. The exchangeable land possibly soluble) reservoir of Al was not depleted during the 6-hour acidification. Sulphate adsorption during the acidification reduced the concentration of SO42- in stream water by as much as 20 mu eq L-1 (from 70 mu eq L-1). Desorption of SO42- and adsorption of base cat ions after the artificial acidification resulted in a prolongation of the pH depression. The streambed had the capacity to buffer stream water chemistry significantly during an acidifying event affecting the entire upstream catchment.
