Workplace flourishing: Measurement, antecedents and outcomes
Authors: Redelinghuys Kleinjan , Rothmann Sebastiaan , Botha Elrie 
Published: December 2018

Orientation: The continuous growth of employee attrition, especially within the highly skilled talent pool, is becoming increasingly problematic. Therefore, one should continually explore the different factors that impact employee retention and performance. This casts the attention to the person–environment fit and workplace flourishing (WF).Research purpose: This study explored relationships among person–environment fit, WF, intention to leave (ITL), in-role performance and organisational citizenship behaviour.Motivation for the study: Disease-driven research heavily outweighs health promotion research. Therefore, more research is needed regarding positive employee behaviours such as strengths, optimal functioning and flourishing.Research approach/design and method: A cross-sectional survey design was used with 258 secondary school teachers from two Gauteng districts. The Perceived Fit, Flourishing-at-Work, Turnover Intention, In-Role Behaviour and Organisational Citizenship Behaviour scales were administered. Structural equation modelling and mediational analyses were performed.Main findings: Results confirmed WF’s three-factor structure. Person–environment fit positively associated with WF. Workplace flourishing negatively related to ITL, while positively relating to in-role performance and organisational citizenship behaviour. Person–environment fit indirectly affected in-role performance and organisational citizenship behaviour via WF.Practical/managerial implications: Organisations should continually modify their strategic frameworks to maintain a healthy balance between individual and environmental characteristics. This will lay the foundation for a favourable work environment. When such an environment is institutionalised, talent retention and performance should follow.Contribution/value-add: The study results should provide new insight into the relationship between the person–environment fit and WF, as well as the effect it may have on ITL and performance.
Simplicial (Co)-homology of
Authors: Farhat Yasser , Gourdeau Frédéric 
Published: December 2018

AbstractWe consider the unital Banach algebra$\ell ^{1}(\mathbb{Z}_{+})$and prove directly, without using cyclic cohomology, that the simplicial cohomology groups${\mathcal{H}}^{n}(\ell ^{1}(\mathbb{Z}_{+}),\ell ^{1}(\mathbb{Z}_{+})^{\ast })$vanish for all$n\geqslant 2$. This proceeds via the introduction of an explicit bounded linear operator which produces a contracting homotopy for$n\geqslant 2$. This construction is generalised to unital Banach algebras$\ell ^{1}({\mathcal{S}})$, where${\mathcal{S}}={\mathcal{G}}\cap \mathbb{R}_{+}$and${\mathcal{G}}$is a subgroup of $\mathbb{R}_{+}$.
Diameter, Decomposability, and Minkowski Sums of Polytopes
Authors: Deza Antoine , Pournin Lionel 
Published: December 2018

AbstractWe investigate how the Minkowski sum of two polytopes affects their graph and, in particular, their diameter. We show that the diameter of the Minkowski sum is bounded below by the diameter of each summand and above by, roughly, the product between the diameter of one summand and the number of vertices of the other. We also prove that both bounds are sharp. In addition, we obtain a result on polytope decomposability. More precisely, given two polytopes $P$ and $Q$, we show that $P$ can be written as a Minkowski sum with a summand homothetic to $Q$ if and only if $P$ has the same number of vertices as its Minkowski sum with $Q$.
Developing a National Database of Radon Test Data in Collaboration with EPA: a Pilot Project to Ascertain Feasibility
Authors: Eggers Carrie 
Published: December 2018

Radon exposure is the second leading cause of lung cancer after smoking and the number one cause among non-smokers. EPA estimates that one in fifteen homes nationwide has elevated radon levels. Public outreach efforts promote radon testing and subsequent mitigation when unsafe levels are found, yet due to varying state regulations, data are non-standardized, making targeted public health actions challenging. An EPA-CDC collaboration will test the feasibility for capturing, analyzing and displaying radon data from state and local health departments by conducting a pilot project to standardize previously non-systemized, uncoordinated data sources into a nationally consistent radon information resource.
Challenges in Surveillance for Chikungunya Virus (CHIKV) Infection
Authors: Lucero-Obusan Cynthia A. , Schirmer Patricia , Oda Gina , Holodniy Mark 
Published: December 2018

We describe challenges and lessons learned using biosurveillance methods for identifying Chikungunya (CHIKV) infections. Surveillance was performed using VA ESSENCE, electronic laboratory data and facility reports. As of Aug. 14, 2014, 21 confirmed/probable cases were identified at 10 hospitals. The principal challenges were lack of a specific ICD-9 code for CHIKV, use of non-specific symptom codes at initial and subsequent encounters, lack of CHIKV testing, long turn-around times for results, poor uniformity in test names, and infection control not being notified of suspected/confirmed CHIKV cases. Based on our experience, a combination surveillance strategy using multiple data sources is essential for CHIKV detection.

Roger Bastide e a difícil identificação de um ideal de transformação agrária camponesa no Brasil
Authors: Vianna Vasconcellos Dora 
Published: December 2018

É possível compreender o lugar ocupado por Roger Bastide no cenário intelectual brasileiro se se toma como referência o seu entendimento acerca do princípio de cisão e de participação africano e o tema da transformação agrária. Com seu africanismo e antietnocentrismo, Roger Bastide pode ter contribuído, sem que esta fosse uma intenção manifesta em seus estudos, para identificar a existência de um ideal camponês de luta pela terra. Essa descoberta o situaria na contracorrente da tradição ensaística conservadora se ele não tivesse posto de lado essa inflexão, preferindo ressaltar as forças de coesãoexistentes na sociedade brasileira.

New genus of subfamily Cypridopsinae Kaufmann, 1933 (Crustacea: Ostracoda) from Thailand
Authors: Savatenalinton Sukonthip 
Published: December 2018

The new genus Thaicypridopsis gen. nov. described here belongs to the tribe Zonocypridini Higuti & Martens, 2012 in the subfamily Cypridopsinae Kaufmann, 1900. It is the first record of the Recent representatives within this tribe in Southeast Asia and Oriental regions. Thaicypridopsis gen. nov. has a number of remarkable characters that distinguish it from other genera in the subfamily: a submarginal row of distinctive tubercles on the postero-ventral part of the right valve in the interior view, a strong serrated claw G2 on the second antenna with an apical concavity, large bristles with hirsute endings and spatula-shaped apexes on all three maxillular endites and a bifurcate tip on the terminal claw of the second thoracopod. One new species, Thaicypridopsis longispinosa sp. nov., is described under this new genus in the present contribution. Apart from the above diagnostic characters, the new species also has long spines on the valve surface as its outstanding feature. The new taxon is morphologically compared with other related species and genera within and outside the subfamily Cypridopsinae. In addition, due to the new genus belonging to a group of genera with the left valve overlapping the right valve in the subfamily, a key to the genera within this group is given.

Sul concetto di fondamento in Karl Leonhard Reinhold (1789-1792). Sei tesi sul passaggio dalla Critica della ragione alla Filosofia elementare
Authors: Fabbianelli Faustino 
Published: December 2018

O conceito de fundamento reinholdiano retoma nominalmente o correspondente conceito kantiano. Se é verdade que em ambos os casos o que funda é aquele elemento que põe o diverso por si de modo determinado, temos que estabelecer como esta relação fundazional tenha que ser compreendida. Para Kant aparece fundamental a questão da síntese, que permite, não apenas diferenciar entre consciência matemática e filosófica, mas também fixar a impossibilidade, para a filosofia, de partir de definições. Reinhold acha que uma filosofia sem apelações, como pretende ser a filosofia elementar, possa ir além dos limites impostos por Kant ao conhecimento filosófico, na medida em que ele é capaz de fundar o saber em fundamentos que, como são absolutamente determinados, explicam a experiência em base ao fato de que não se pode duvidar sobre eles. O tema da notio, ou seja da omnimoda determinatio, em torno ao qual girava boa pare da discussão da escolástica leibniziano-wollfiana no que diz respeito à definição e à cognoscibilidade de uma coisa, é retomado por Reinhold no âmbito de uma filosofia transcendental que vai além de Kant e que abre as portas aos grandes sistemas da filosofia clássica alemã.

Published: December 2018

AbstractPurposeThe main objective of this study was to develop a technique to accurately determine the air gap between the end of the proton beam compensator and the body of the patient in proton radiotherapy.MethodsOrthogonal x‐ray image‐based automatic coordinate reconstruction was used to determine the air gap between the patient body surface contour and the end of beam nozzle in proton radiotherapy. To be able to clearly identify the patient body surface contour on the orthogonal images, a radiopaque wire was placed on the skin surface of the patient as a surrogate. In order to validate this method, a Rando® head phantom was scanned and five proton plans were generated on a Mevion S250 Proton machine with various air gaps in Varian Eclipse Treatment Planning Systems (TPS). When setting up the phantom in a treatment room, a solder wire was placed on the surface of the phantom closest to the beam nozzle with the knowledge of the beam geometry in the plan. After the phantom positioning was verified using orthogonal kV imaging, the last pair of setup kV images was used to segment the solder wire and the in‐room coordinates of the wire were reconstructed using a back‐projection algorithm. Using the wire as a surrogate of the body surface, we calculated the air gaps by finding the minimum distance between the reconstructed wire and the end of the compensator. The methodology was also verified and validated on clinical cases.ResultsOn the phantom study, the air gap values derived with the automatic reconstruction method were found to be within 1.1 mm difference from the planned values for proton beams with air gaps of 85.0, 100.0, 150.0, 180.0, and 200.0 mm. The reconstruction technique determined air gaps for a patient in two clinical treatment sessions were 38.4 and 41.8 mm, respectively, for a 40 mm planned air gap, and confirmed by manual measurements. There was strong agreement between the calculated values and the automatically measured values, and between the automatically and manually measured values.ConclusionsAn image‐based automatic method has been developed to conveniently determine the air gap of a proton beam, directly using the orthogonal images for patient positioning without adding additional imaging dose to the patient. The method provides an objective, accurate, and efficient way to confirm the target depth at treatment to ensure desired target coverage and normal tissue sparing.
Using Synthetic Biology to Engineer Spatial Patterns
Authors: Santos‐Moreno Javier , Schaerli Yolanda 
Published: December 2018

AbstractSynthetic biology has emerged as a multidisciplinary field that provides new tools and approaches to address longstanding problems in biology. It integrates knowledge from biology, engineering, mathematics, and biophysics to build—rather than to simply observe and perturb—biological systems that emulate natural counterparts or display novel properties. The interface between synthetic and developmental biology has greatly benefitted both fields and allowed to address questions that would remain challenging with classical approaches due to the intrinsic complexity and essentiality of developmental processes. This Progress Report provides an overview of how synthetic biology can help to understand a process that is crucial for the development of multicellular organisms: pattern formation. It reviews the major mechanisms of genetically encoded synthetic systems that have been engineered to establish spatial patterns at the population level. Limitations, challenges, applications, and potential opportunities of synthetic pattern formation are also discussed.

Published: December 2018

AbstractMemristive devices based on mixed ionic–electronic resistive switches have an enormous potential to replace today's transistor‐based memories and Von Neumann computing architectures thanks to their ability for nonvolatile information storage and neuromorphic computing. It still remains unclear however how ionic carriers are propagated in amorphous oxide films at high local electric fields. By using memristive model devices based on LaFeO3 with either amorphous or epitaxial nanostructures, we engineer the structural local bonding units and increase the oxygen‐ionic diffusion coefficient by one order of magnitude for the amorphous oxide, affecting the resistive switching operation. We show that only devices based on amorphous LaFeO3 films reveal memristive behavior due to their increased oxygen vacancy concentration. We achieved stable resistive switching with switching times down to microseconds and confirm that it is predominantly the oxygen‐ionic diffusion character and not electronic defect state changes that modulate the resistive switching device response. Ultimately, these results show that the local arrangement of structural bonding units in amorphous perovskite films at room temperature can be used to largely tune the oxygen vacancy (defect) kinetics for resistive switches (memristors) that are both theoretically challenging to predict and promising for future memory and neuromorphic computing applications.
