Creating A Creative State of Mind: Promoting Creativity Through Proactive Vitality Management and Mindfulness

Most research on employee creativity has been focused on relatively distal antecedents, such as personality or job characteristics, which has resulted in top-down organizational approaches to promote employee creativity. However, such approaches overlook the self-regulating potential of employees and may not explain intraindividual fluctuations in creativity. In the present research, we build on proactive motivation theory to examine how employees may promote their own creativity on a daily basis through the use of proactive vitality management (PVM). To better understand the PVM-creativity link, we zoom in on this process by examining the role of mindfulness as an underlying mechanism. In two daily diary studies, employees from the United States (N = 133 persons, n = 521 data points) and the creative industry in Germany (N = 62 persons, n = 232 data points) reported on their use of PVM and states of mindfulness for five consecutive workdays. Additionally, participants completed a daily creativity test (brainstorming task) in Study 1, whereas supervisors rated participants' daily creative work performance in Study 2. In both studies, multilevel analyses showed that daily PVM was positively related to creative performance through daily mindfulness, supporting our hypotheses. These replicated findings suggest that individuals may bring themselves in a cognitive, creative state of mind on a daily basis, emphasizing the importance of proactive behavior in the creative process

Proactive vitality management in the work context

In the present research, we use proactivity literature and studies on energy at work to argue that individuals may proactively manage their vitality (i.e., physical and mental energy) to promote optimal functioning at work. We develop and validate a scale to measure proactive vitality management (PVM), and explore the nomological network. We conducted a five-day diary study (N = 133; 521 days), a survey study (N = 813) and a cross-sectional study measuring daily PVM (N = 246) among working individuals from various occupational sectors. The results show that PVM can be reliably measured with eight items that load on one overall factor, both on general and daily level. Furthermore, daily PVM was moderately but positively related to the use of work-related strategies and micro-breaks. Moreover, PVM related positively to relevant personal characteristics (i.e., proactive personality and self-insight) and showed moderate but positive relationships with job crafting and relaxation (convergent validity). PVM was unrelated to psychological detachment and decreasing hindering demands (discriminant validity). Finally, PVM was positively related to well-being, in-role work performance, creative work performance and performance on the Remote Associates Test (criterion validity). We conclude that employees may promote their own work performance through the use of PVM

On the interaction between intrinsic proteins and phosphatidylglycerol in the membrane of Acholeplasma laidlawii

About 30% of the phosphatidylglycerol in oleic acid-enriched Acholeplasma laidlawii membranes are not hydrolyzed at temperatures below 10 °C by phospholipase A2 from porcine pancreas. Removal of 53% of the membrane proteins by proteolysis did not reduce the size of this inaccessible phosphatidylglycerol pool. However, modification of the membrane proteins with 2,4,6-trinitrobenzenesulfonic acid or glutaraldehyde did make an additional 70% of this protected pool of phosphatidylglycerol accessible to phospholipase A2. Complete hydrolysis of phosphatidylglycerol at low incubation temperatures was achieved only after heat treatment of the membranes which resulted in an extensive aggregation of intrinsic membrane proteins as visualized by freeze-etch electron microscopy. Phospholipase A2 from bee venom was more effective in hydrolyzing phosphatidylglycerol at low temperature than the pancreatic enzyme. These results show that the inaccessibility of phosphatidylglycerol is not due to resealing of isolated membranes, the presence of a crystalline phase in the membrane lipids, or a shielding effect of surface proteins. The protection against hydrolysis may be due to an interaction of phosphatidylglycerol with intrinsic membrane proteins which is stabilized at low temperatures. Increasing the temperature favors the exchange of protein-bound phosphatidylglycerol with other membrane lipids resulting in complete hydrolysis

Action of phospholipase A2 and phospholipase C on Escherichia coli

The action of exogenous phospholipases on Escherichia coli has been examined. Cells harvested in late log phase were found to be completely resistant to the action of phospholipases A2 and C. Treatment of cells with Tris and EDTA was required to make the phospholipids in the cell accessible to these phospholipases. Phospholipase A2 hydrolyzed mainly phosphatidylethanolamine and phosphatidylglycerol, whereas phospholipase C preferentially degraded phosphatidylethanolamine. During the EDTA treatment, an endogenous phospholipase A1 or a lysophospholipase (or both) was unmasked which caused the formation of free fatty acids in experiments in which no phospholipase was added and which degraded some of the lysophospholipids formed by phospholipase A2. The cells were rapidly killed by the successive Tris-EDTA-phospholipase treatment, but no cell disintegration was observed

A monolayer study of the reaction of trinitrobenzene sulphonic acid with amino phospholipids

The reaction of trinitrobenzene sulphonic acid with amino phospholipids, and in particular phosphatidylethanolamine has been studied by the monolayer technique. Injection of trinitrobenzene sulphonic acid under a monolayer of amino phospholipid results in an increase in surface pressure. The rate and extent of the pressure change is greatly affected by the initial surface pressure, the fatty acid composition of the lipid, and the presence of other non-reactive lipids, especially negatively charged phospholipids. The extent of the reaction was measured with 32P-labelled phospholipids isolated from Bacillus subtilis. Only about 80% of the phosphatidylethanolamine in the monolayer could be converted to its trinitrophenyl derivative. In the presence of negatively charged phospholipids such as cardiolipin or phosphatidylglycerol, a further 20% decrease in the trinitrophenylation of phosphatidylethanolamine was found. The pressure increase occurring during trinitrophenylation could also be correlated with the extent of the reaction by comparison of the force-area curves of pure phosphatidylethanolamine, its trinitrophenyl derivative and mixtures of both compounds. The data may offer an explanation for the observation that incomplete labelling of amino phospholipids frequently occurs in natural membranes and furthermore indicate that the use of chemical labelling techniques in the study of lipid asymmetry in biological membranes must be approached with great caution

Proactive Vitality Management and Creative Work Performance: The Role of Self-Insight and Social Support

Integrating proactivity and creativity literatures, we argue that people can perform more creatively at work when they proactively manage their levels of vitality. Proactive vitality management is defined as individual, goal-oriented behavior aimed at managing physical and mental energy to promote optimal functioning at work. We hypothesize that this process may be facilitated by being aware of one's own state and by support from others. A total of 242 employees participated in a weekly diary study for three consecutive weeks, yielding 610 observations. Results of multilevel analyses show that participants reported more creative work performance during weeks in which they had proactively used vitality management. In addition, in line with our predictions, self-insight and social support for creativity in the workplace acted as cross-level moderators and strengthened the relationship between proactive vitality management and creativity. We conclude that a proactive approach regarding physical and mental energy is a
