Nature and Lability of Northern Adriatic Macroaggregates

The key organic constituents of marine macroaggregates (macrogels) of prevalently phytoplankton origin, periodically occurring in the northern Adriatic Sea, are proteins, lipids and especially polysaccharides. In this article, the reactivity of various macroaggregate fractions in relation to their composition in order to decode the potentially »bioavailable« fractions is summarized and discussed. The enzymatic hydrolysis of the macroaggregate matrix, using α-amylase, β-glucosidase, protease, proteinase and lipase, revealed the simultaneous degradation of polysaccharides and proteins, while lipids seem largely preserved. In the fresh surface macroaggregate samples, a pronounced degradation of the α-glycosidic bond compared to β-linkages. Degradation of the colloidal fraction proceeded faster in the higher molecular weight (MW) fractions. N-containing polysaccharides can be important constituents of the higher MW fraction while the lower MW constituents can mostly be composed of poly- and oligosaccharides. Since the polysaccharide component in the higher MW fraction is more degradable compared to N-containing polysaccharides, the higher MW fraction represents a possible path of organic nitrogen preservation. Enzymatic hydrolysis, using α-amylase and β-glucosidase, revealed the presence of α- and β-glycosidic linkages in all fractions with similar decomposition kinetics. Our results indicate that different fractions of macroaggregates are subjected to compositional selective reactivity with important implications for macroaggregate persistence in the seawater column and deposition

Satisfaction with life and job satisfaction of employees in Slovenian army

The purpose of this study was to investigate satisfaction with life and job satisfaction in the Slovenian army. For this purpose we used Satisfaction With Life Scale (Diener, Emmons, Larsen, & Griffin, 1985) and Pogačnik's (2003) Job Satisfaction Scale. This research involved 168 employees of the Slovenian army: 68 soldiers, 60 officers, and 40 noncommissioned officers. The results showed that employees in Slovenian army are more satisfied than unsatisfied with their lives. Officers are the most satisfied with their life. We found out that appraisals on job satisfaction are rather low and indicate middle level of job satisfaction. The highest level of work satisfaction was expressed in the area of relations with co-workers. Participants were least satisfied with their salary and other material facilities. Individuals with subordinate co-workers showed higher level of satisfaction with work conditions, possibilities for promotion, salary and other material facilities, and also higher level of satisfaction about informing in the army, possibilities for professional development, independence and autonomy at work, work reputation, creativeness at work and also taking part in decision-making. Analysis of differences showed that officers gave the highest score to indicators of work satisfaction, with exception of independence and autonomy at work, work reputation, and pretentiousness of work. Based on the examination of the actual state, to the level the research was enabling, we identified some necessary changes, improvements or measures for improvement of the recognized weak areas
