Spontaneous spondylodiscitis should be considered in every patient with back pain accompanied by fever and laboratory markers of inflammation. The major predisposing risk factor seems to be uncontrolled diabetes. MRI appears to be the method of choice for confirming diagnosis. Timely and accurate diagnosis along with prompt administration of antibiotics appears mandatory for a favorable outcome and avoidance of surgical intervention.

The present study examined relationships between leaders' emotional intelligence (EI) and subordinates' emotion and work attitudes and between leaders' and subordinates' EI and work outcomes. School directors and educators completed measures of EI, affect at work, job satisfaction, and burnout. A series of multilevel analyses found that leaders' use of emotion was positively related to subordinates' work emotionality and attitudes, whereas leaders' emotion regulation and selfemotion appraisal were negatively related to subordinates' emotion and work attitudes. Leaders' and subordinates' own EI was positively related to their own work emotionality and job satisfaction. These findings support a social interactionist perspective on emotions at work and a multilevel understanding of the effects of leaders' emotions intrapersonally and interpersonally.j asp_750 1121..1144

a b s t r a c tResearch on students' motivation has mainly focused on interpersonal differences rather than on the ongoing, intrapersonal dynamics that forge students' everyday life. In this five-month longitudinal (diary) study, we recruited a sample of 179 high school students from Greece (35.8% males; M age = 16.27; SD = 1.02) to investigate through multilevel analyses the ongoing dynamics of students' motivation. We did so by examining the relation between autonomous functioning and aspects of study regulation (namely, study efforts and procrastination) and well-being (namely, subjective vitality and depressive feelings). After controlling for perceived competence, we found week-to-week autonomous functioning to relate positively to study efforts and subjective vitality and negatively to procrastination and depressive feelings. Interestingly, implicit theories of ability -the degree to which one believes that ability is fixed or amenable -were found to moderate the week-to-week relations of autonomous functioning to study efforts and homework procrastination. In particular, autonomous functioning co-varied positively to study efforts and negatively to homework procrastination only among students who believed that ability is malleable. Also, beliefs that ability is fixed predicted poorer grades, lower mean levels of study efforts, and higher homework procrastination. The results underscore the necessity of taking a more dynamic view when studying motivational phenomena and the importance of jointly considering the implicit theory framework and self-determination theory.
