Gamification Research: a 50-years Retrospective from PBLs Towards Conscious Evolution

Abstract This paper presents a critical design fiction in the format of an envisioned plausible future scenario for gamification research and practice in the next years. We envision a possible path that gamification research can take that would lead it to effectively being able to help develop human potential, increase wellbeing, and contribute to conscious evolution in the future. Our goal is to promote reflection and discussion on the topic

"Hot" Surface Activation of Molecular Complexes: Insight from Modeling Studies

Rock-and-roll over hot floors: Theoretical modeling of the first activation stages of a Cu complex on top of a heated surface (750 K) revealed two mobility regimes, a slow bump-and-rock diffusion over the surface and a fast roll-and-go motion accompanied by significant temperature-induced bond oscillations. This study enables a deeper insight into "hot" surface molecular activation processes.Tanz auf dem Vulkan: Das Modellieren der ersten Aktivierungsstufen eines Cu-Komplexes auf einer beheizten Oberfl\ue4che (750\u2005K) enth\ufcllte zwei Bewegungsarten: eine langsame Diffusion durch \u201eAnsto fen und Taumeln\u201c und eine schnelle Rollbewegung, die mit deutlichen temperaturinduzierten Bindungsoszillationen einhergeht.

Electron transport through single Mn12 molecular magnets

We report transport measurements through a single-molecule magnet, the Mn12 derivative [Mn12O12(O2C-C6H4-SAc)16(H2O)4], in a single-molecule transistor geometry. Thiol groups connect the molecule to gold electrodes that are fabricated by electromigration. Striking observations are regions of complete current suppression and excitations of negative differential conductance on the energy scale of the anisotropy barrier of the molecule. Transport calculations, taking into account the high-spin ground state and magnetic excitations of the molecule, reveal a blocking mechanism of the current involving non-degenerate spin multiplets.Comment: Accepted for Phys.

CLEVER: A Gameful Enterprise Learning System

Employees often lack the motivation to share their implicit knowledge with one another and are reluctant to engage in a collaborative forum for such knowledge exchange. To address this issue, we developed a gameful learning component of an enterprise knowledge management system (KMS) to help foster this process of collaborative and participatory learning. This paper introduces CLEVER, a serious game that combines trivia and strategy elements as game elements to motivate the players into knowledge exchange. Furthermore, we describe how CLEVER uses intrinsic and extrinsic motivational affordances to engage employees into enterprise knowledge learning

The ASCE EUV Polarimeter

Abstract. The SOHO mission has achieved important results in the physics of solar wind and coronal mass ejection acceleration, but most of the processes that drive this acceleration have not yet been explained. The Advanced Spectroscopic and Coronagraphic Explorer (ASCE) mission will carry on-board spectroscopic and polarimetric instrumentation of new generation that is designed to address the fundamental questions on this processes. Following a brief description of ASCE scientific objectives and instrumentation, the EUV polarimetric channel is described. The EUV Polarimeter (EUVP) is designed to measure for the first time the magnetic field vector in the extended corona through the Hanle effect, and the anisotropy of the ion velocity. The EUVP represents the contribution of the Italian solar physics community to the ASCE mission

VARIÁVEIS RELACIONADAS E NASCIMENTO DE RECÉM-NASCIDOS GRANDES PARA IDADE GESTACIONAL NO DIABETES MELLITUS GESTACIONAL

Introdução: O diabetes mellitus gestacional apresenta prevalência de três a vinte e cinco por cento das gestações com variaçãode acordo com a população. Objetivo: Identificar as variáveis relacionadas com recém-nascidos grandes para idade gestacionalem pacientes com diabetes mellitus gestacional e os seus desfechos obstétricos. Métodos: Estudo de corte retrospectivo desenvolvidono período de janeiro de 2013 a abril de 2016 em uma maternidade pública. Utilizou-se uma regressão logística multinominalpara cálculo de razão de chance, com intervalo de confiança de 95%. Resultados: Os preditores clínicos e laboratoriais:idade gestacional de diagnóstico, índice de massa corporal e ganho de peso, glicemias médias de jejum e pós-prandial não apresentaramdiferenças. A hemoglobina glicada apresentou significância na análise bruta (OR= 2,57; IC95% 1,05-6,30), porém nãosustentada na ajustada (OR=2,18; IC95% 0,80-5,90). Os desfechos perinatais: apgar e ingresso em unidade de tratamento intensivonão demonstraram diferenças. Recém-nascidos grandes para idade gestacional foram relevantes quanto à via de parto cesariana,com valores brutos (OR=1,73; IC95% 1,21-2,4) e ajustados (OR=1,71; IC95% 1,20-2,43). Conclusão: Não foram encontradosfatores que isoladamente estão relacionados com o nascimento de recém-nascidos grandes para a idade gestacional. Nosdesfechos perinatais, recém-nascidos grandes para a idade gestacional apresentam maiores chances de partos cesáreos.Palavras-chave: Gravidez. Índice glicêmico. Recém-nascido

Biocontrol traits of Bacillus licheniformis GL174, a culturable endophyte of Vitis vinifera cv. Glera

Background Bacillus licheniformis GL174 is a culturable endophytic strain isolated from Vitis vinifera cultivar Glera, the grapevine mainly cultivated for the Prosecco wine production. This strain was previously demonstrated to possess some specific plant growth promoting traits but its endophytic attitude and its role in biocontrol was only partially explored. In this study, the potential biocontrol action of the strain was investigated in vitro and in vivo and, by genome sequence analyses, putative functions involved in biocontrol and plant-bacteria interaction were assessed. Results Firstly, to confirm the endophytic behavior of the strain, its ability to colonize grapevine tissues was demonstrated and its biocontrol properties were analyzed. Antagonism test results showed that the strain could reduce and inhibit the mycelium growth of diverse plant pathogens in vitro and in vivo. The strain was demonstrated to produce different molecules of the lipopeptide class; moreover, its genome was sequenced, and analysis of the sequences revealed the presence of many protein-coding genes involved in the biocontrol process, such as transporters, plant-cell lytic enzymes, siderophores and other secondary metabolites. Conclusions This step-by-step analysis shows that Bacillus licheniformis GL174 may be a good biocontrol agent candidate, and describes some distinguished traits and possible key elements involved in this process. The use of this strain could potentially help grapevine plants to cope with pathogen attacks and reduce the amount of chemicals used in the vineyard
