Understanding social creativity amongst event professionals : an action research approach

Live events represent a significant and growing sector of the creative industries but the creative process underlying this sector is little researched in the event management context. Despite the increased consumption of virtual and online media, the live event remains a popular channel of expression for a wide range of creative art forms and commercial messages. Live events use such messages as \u27props\u27 or \u27stages\u27 to produce memorable and emotionally positive moments for audiences. The creative process behind developing a live event is in itself a live event, involving groups of event professionals working in a social context to conceptualise ideas for their audiences. This research fills the gap for event professionals in the creative industries by seeking to understand the creative process intrinsic to live events. This paper suggests that social creativity is used to develop live event concepts. The phenomenon of social creativity identified from the existing literature is explored in the context of its application to event professionals. An Action Research approach is recommended to better understand the key antecedents of social creativity and how they can influence event concept development.<br /

Understanding the Importance of Creativity Towards Psychological Safety in the Library Workplace

Employee Engagement is one of the leading factors toward organizational success. Happier employees are engaged employees. However, employees cannot reach engagement unless there are feelings of psychological safety. One tool that libraries can utilize to increase the engagement of their staff is to invest in opportunities for workplace creativity

Reply Brief. Crouse v. Caldwell, 138 S.Ct. 470 (2017) (No. 17-242), 2017 U.S. S. Ct. Briefs LEXIS 4102, 2017 WL 4918297

QUESTIONS PRESENTED (1) When disputes of fact arise regarding whether speech by a public employee is protected by the First Amendment, should those factual issues be resolved by a trier of fact (the rule in the Second, Third, Sixth, Eighth and Tenth Circuits), or by the court as a matter of constitutional law (the rule in the Fourth Circuit)? (2) When a government employee engages in speech on a subject of public concern, and a court applying Pickering balances the First Amendment interest against any contrary interests of the employer, should the extent of that First Amendment interest be “lessened” -as the Fourth Circuit holds - if the speaker directed his or her statements to one person rather than the “larger public,” was motivated by some “ personal concern” in speaking about that subject, or was “not providing a particularly informed opinion”? (3) Can a defendant establish qualified immunity under Garcetti v. Ceballos, by showing that he or she could reasonably have believed that the action of the plaintiff was in his “capacity” as an employee (the rule in the Fourth Circuit), or only by showing he or she could reasonably have believed that the plaintiff spoke “pursuant to his professional responsibilities” (the rule in the First, Fifth and Ninth Circuits)

The heterogeneous nature of Fe delivery from melting icebergs

The micronutrient iron (Fe) can be transported from marine terminating glaciers to the ocean by icebergs. There are however few observations of iceberg Fe content, and the flux of Fe from icebergs to the offshore surface ocean is poorly constrained. Here we report the dissolved Fe (DFe), total dissolvable Fe (TdFe) and ascorbic acid extractable Fe (FeAsc) sediment content of icebergs from Kongsfjorden, Svalbard. The concentrations of DFe (range 0.63 nM – 536 nM, mean 37 nM, median 6.5 nM) and TdFe (range 46 nM – 57 µM, mean 3.6 µM, median 144 nM) both demonstrated highly heterogeneous distributions and there was no significant correlation between these two fractions. FeAsc (range 0.0042 to 0.12 wt. %) was low compared to both previous measurements in Kongsfjorden and to current estimates of the global mean. FeAsc content per volume ice did however, as expected, show a significant relationship with sediment loading (which ranged from < 0.1 – 234 g L-1 of meltwater). In the Arctic, icebergs lose their sediment load faster than ice volume due to the rapid loss of basal ice after calving. We therefore suggest that the loss of basal ice is a potent mechanism for the reduction of mean TdFe and FeAsc per volume of iceberg. Delivery of TdFe and FeAsc to the ocean is thereby biased towards coastal waters where, in Kongsfjorden, DFe (18 ± 17 nM) and TdFe (mean 8.1 µM, median 3.7 µM) concentrations were already elevated

Review article: How does glacier discharge affect marine biogeochemistry and primary production in the Arctic?

Freshwater discharge from glaciers is increasing across the Arctic in response to anthropogenic climate change, which raises questions about the potential downstream effects in the marine environment. Whilst a combination of long-term monitoring programmes and intensive Arctic field campaigns have improved our knowledge of glacier-ocean interactions in recent years, especially with respect to fjord/ocean circulation, there are extensive knowledge gaps concerning how glaciers affect marine biogeochemistry and productivity. Following two cross-cutting disciplinary International Arctic Science Committee (IASC) workshops addressing the importance of glaciers for the marine ecosystem, here we review the state of the art concerning how freshwater discharge affects the marine environment with a specific focus on marine biogeochemistry and biological productivity. Using a series of Arctic case studies (Nuup Kangerlua/Godthäbsfjord, Kongsfjorden, Kangerluarsuup Sermia/Bowdoin Fjord, Young Sound and Sermilik Fjord), the interconnected effects of freshwater discharge on fjord-shelf exchange, nutrient availability, the carbonate system, the carbon cycle and the microbial food web are investigated. Key findings are that whether the effect of glacier discharge on marine primary production is positive or negative is highly dependent on a combination of factors. These include glacier type (marine- or land-terminating), fjord-glacier geometry and the limiting resource(s) for phytoplankton growth in a specific spatio-temporal region (light, macronutrients or micronutrients). Arctic glacier fjords therefore often exhibit distinct discharge-productivity relationships, and multiple case-studies must be considered in order to understand the net effects of glacier discharge on Arctic marine ecosystems

Evaluation of a ferrozine based autonomous in situ lab-on-chip analyzer for dissolved iron species in coastal waters

The trace metal iron (Fe) is an essential micronutrient for phytoplankton growth and limits, or co-limits primary production across much of the world's surface ocean. Iron is a redox sensitive element, with Fe(II) and Fe(III) co-existing in natural waters. Whilst Fe(II) is the most soluble form, it is also transient with rapid oxidation rates in oxic seawater. Measurements of Fe(II) are therefore preferably undertaken in situ. For this purpose an autonomous wet chemical analyzer based on lab-on-chip technology was developed for the in situ determination of the concentration of dissolved (<0.45 μm) Fe species (Fe(II) and labile Fe) suitable for deployments in a wide range of aquatic environments. The spectrophotometric approach utilizes a buffered ferrozine solution and a ferrozine/ascorbic acid mixture for Fe(II) and labile Fe(III) analyses, respectively. Diffusive mixing, color development and spectrophotometric detection take place in three separate flow cells with different lengths such that the analyzer can measure a broad concentration range from low nM to several μM of Fe, depending on the desired application. A detection limit of 1.9 nM Fe was found. The microfluidic analyzer was tested in situ for nine days in shallow waters in the Kiel Fjord (Germany) along with other sensors as a part of the SenseOCEAN EU-project. The analyzer's performance under natural conditions was assessed with discrete samples collected and processed according to GEOTRACES protocol [acidified to pH < 2 and analyzed via inductively coupled plasma mass spectrometry (ICP-MS)]. The mechanical performance of the analyzer over the nine day period was good (consistent high precision of Fe(II) and Fe(III) standards with a standard deviation of 2.7% (n = 214) and 1.9% (n = 217), respectively, and successful completion of every programmed data point). However, total dissolved Fe was consistently low compared to ICP-MS data. Recoveries between 16 and 75% were observed, indicating that the analyzer does not measure a significant fraction of natural dissolved Fe species in coastal seawater. It is suggested that an acidification step would be necessary in order to ensure that the analyzer derived total dissolved Fe concentration is reproducible and consistent with discrete values
