Leveraging public health's participation in a Health Information Exchange to improve communicable disease reporting
Authors: Painter Ian , Revere Debra , Gibson P. Joseph , Baseman Janet 
Published: September 2017

Background: Infectious diseases can appear and spread rapidly. Timely information about disease patterns and trends allows public health agencies to quickly investigate and efficiently contain those diseases. But disease case reporting to public health has traditionally been paper-based, resulting in somewhat slow, burdensome processes. Fortunately, the expanding use of electronic health records and health information exchanges has created opportunities for more rapid, complete, and easily managed case reporting and investigation. To assess how this new service might impact the efficiency and quality of a public health agency's case investigations, we compared the timeliness of usual case investigation to that of case investigations based on case report forms that were partially pre-populated with electronic data. Intervention: Between September 2013-March 2014, chlamydia disease report forms for certain clinics in Indianapolis were electronically pre-populated with clinical, lab and patient data available through the Indiana Health Information Exchange, then provided to the patient’s doctor. Doctors could then sign the form and deliver it to public health for investigation and population-level disease tracking. Methods: We utilized a novel matched case analysis of timeliness changes in receipt and processing of communicable disease report forms. Each Chlamydia cases reported with the pre-populated form were matched to cases reported in usual ways. We assessed the time from receipt of the case at the public health agency: 1) inclusion of the case into the public health surveillance system and 2) to close to case. A hierarchical random effects model was used to compare mean difference in each outcome between the target cases and the matched cases, with random intercepts for case. Results: Twenty-one Chlamydia cases were reported to the public health agency using the pre-populated form. Sixteen of these pre-populated form cases were matched to at least one other case, with a mean of 23 matches per case. The mean Reporting Lag for the pre-populated form cases was 2.5 days, which was 2.7 days shorter than the mean Reporting Lag for the matched controls (p = <0.001). The mean time to close a pre-populated form case was 4.7 days, which was 0.2 days shorter than time to close for the matched controls (p = 0.792). Conclusions: Use of pre-populated forms significantly decreased the time it took for the local public health agency to begin documenting and closing chlamydia case investigations. Thoughtful use of electronic health data for case reporting may decrease the per-case workload of public health agencies, and improve the timeliness of information about the pattern and spread of disease.
Using Human Resource Management Practices to Predict Quality Service Delivery: Case of Public Secondary Schools in Kenya
Authors: Mutiso Christine , Kilika James M. 
Published: September 2017

With rapid changes in the business environment, organizations are increasingly looking at their human resources as a unique asset that can provide sustained competitive advantage. Human resources are considered by many to be the most important assets of an organization for sustaining competitiveness through their products and services. It has been observed that very few employers are able to harness the full potential from their human resources. In view of this, this study examined the relationship between Human Resource Management Practices and Quality Service Delivery in the education sector in Kenya. The research was done as a case study of government sponsored secondary schools based in in Taita-Taveta County. The conceptualization in the study was guided by the various strategic human resource theories, models and the servqual model. The results show that the regression model used is significant (F=23.499; p<0.001) and that the HRM practices as measured using the five practices explain approximately 45% of the variation in service quality delivery in the education sector in Taita-Taveta county in Kenya (R2=0.448). The results show that hypotheses one, four and five of the study are supported (β=.405, p<.000;β=.321, p<.000; β= .181, p<.001 respectively) while hypotheses two and three are not (β=-.113, p=.170; β= -.508, p=.612 respectively). The study concluded that HRM practices in the Education sector in Kenya is still undertaken with an inclination towards the traditional personnel management perspective. The study called on future research to investigate the same phenomenon using an expanded list of HRM Practices indicators and pay attention to senior executives’ perspective on the strategic role of human resources in the sector.

<p>La formación del profesorado en el uso de las TIC es un aspecto importante para conseguir una verdadera integración de las TIC en la educación. Según el modelo TPAK, esta formación no debe limitarse a contemplar de manera separada los aspectos relacionados con las TIC, el contenido curricular y la metodología. En el presente estudio se explora la percepción de autoeficacia en cuanto al uso de las TIC en el aula de una muestra de 107 estudiantes de los grados de Maestro/a en Educación Infantil y Maestro/a en Educación Primaria. Para ello se emplea una traducción del cuestionario para la autoevaluación de las competencias TIC elaborado por Tondeur et al. (2016). Los resultados del estudio muestran que los estudiantes de Magisterio se perciben a sí mismos como más competentes en el uso de las TIC que en la toma de decisiones pedagógicas relacionadas con dicho uso. Además, se halló una correlación estadísticamente significativa entre las horas de formación recibidas en el uso educativo de las TIC y la percepción de autoeficacia en este mismo uso educativo de las TIC. Estos resultados conllevan algunas implicaciones en la toma de decisiones respecto a la formación del profesorado.</p>

AbstractMagnetosheath plasma usually determines properties of asymmetric magnetic reconnection at the subsolar region of Earth's magnetopause. However, cold plasma that originated from the ionosphere can also reach the magnetopause and modify the kinetic physics of asymmetric reconnection. We present a magnetopause crossing with high‐density (10–60 cm−3) cold ions and ongoing reconnection from the observation of the Magnetospheric Multiscale (MMS) spacecraft. The magnetopause crossing is estimated to be 300 ion inertial lengths south of the X line. Two distinct ion populations are observed on the magnetosheath edge of the ion jet. One population with high parallel velocities (200–300 km/s) is identified to be cold ion beams, and the other population is the magnetosheath ions. In the deHoffman‐Teller frame, the field‐aligned magnetosheath ions are Alfvénic and move toward the jet region, while the field‐aligned cold ion beams move toward the magnetosheath boundary layer, with much lower speeds. These cold ion beams are suggested to be from the cold ions entering the jet close to the X line. This is the first observation of the cold ionospheric ions in the reconnection outflow region, including the reconnection jet and the magnetosheath boundary layer.
Out of the woods: Driftwood insights into Holocene pan‐Arctic sea ice dynamics
Authors: Hole Georgia M. , Macias‐Fauria Marc 
Published: September 2017

AbstractThe collation of 913 driftwood samples from across the western Arctic, with spatiotemporal distribution and available provenance data, enabled the production of a high‐resolution proxy‐based reconstruction of Holocene Arctic Ocean surface current and sea ice dynamics. Regionally bounded, driftwood‐based sea ice reconstructions studies suggest spatiotemporally complex past Arctic sea ice extent and movement; however, a large‐scale compilation of Holocene Arctic driftwood has not previously been developed. Sparse driftwood in the early Holocene (≥8.2 cal ka B.P.) deglacial period was followed by increased driftwood deposition in the warmer mid‐Holocene (8.2–4.2 cal ka B.P.); characterized by an enhanced Transpolar Drift (TPD) ∼7 cal ka B.P., leading to sea ice loss through the Fram Strait. Driftwood incursion peaks show spatial E‐W progression from the Eurasian Archipelagos to Greenland and the Canadian Arctic Archipelago, suggesting a progressive shift in the orientation of the TPD on centennial‐millennial time scales and intermediate phases in the Arctic Oscillation. Late Holocene cooling (≤4.2 cal ka B.P.) is indicated by increased influx of probably North American Picea via a strengthened Beaufort Gyre (BG) which enhanced sea ice recirculation, starting in the western Arctic and progressing eastward. In recent millennia (<2 cal ka B.P.), a more variable driftwood record alternates between BG and TPD dominance on centennial time scales. To further constrain a spatiotemporal reconstruction of variations in Holocene ocean current and sea ice dynamics, a more definitive determination of driftwood provenance is recommended to build upon the current framework, such as through radiogenic isotope tracing and aDNA analysis.

Published: September 2017

AbstractMaterials decorated by the hierarchical micro‐nanostructures similar to lotus leaf surface topographies are firmly considered to possess the substantial anti‐icing functions, showing icing‐delay and low ice adhesion. Here, the aim of this work is to verify the anti‐icing capacity in the actual icing environment containing supercooled airflow. This study, therefore, develops both routes to fabricate the hierarchical micro‐nanostructure and single nanostructure superhydrophobic surfaces, and first evaluates their anti‐icing capacity based on the routine measuring strategies in laboratory. Also, the potential application environment is modeled and used to verify their anti‐icing performance for further guiding rational design of surface structures of anti‐icing materials. Due to the double‐scale effect, the hierarchical micro‐nanostructure can induce more air pockets to produce the higher hydrophobicity and anti‐icing capacity based on the big reference droplets (diameter > 2 mm) and even static water. However, the verified results in the potential application environment demonstrate that the hierarchical micro‐nanostructure exhibits the inferior anti‐icing performance, comparing with the single nanostructure. The icing area on the single nanostructure surface is almost half of that on the hierarchical micro‐nanostructure surface, also causing a reduction of ≈26 g in icing mass.

Published: September 2017

AbstractDirect C5‐alkylation of oxazole/thiazole with ether or cycloalkane has been achieved through a cobalt‐catalyzed cross‐dehydrogenative coupling (CDC) process in moderate to good yields. This transformation represents the first C(sp2)−C(sp3) cross‐coupling at the C5‐position of the oxazole/thiazole via double C−H bond cleavages. Various functional groups on oxazole/thiazole substrates, as well as water and air, are well‐tolerated with this concise and practical protocol, constituting straightforward access to heterocycles with great medicinal significance. A preliminary mechanism involving a radical process has also been proposed.
When does social exclusion increase or decrease food self‐regulation? The moderating role of time orientation

Published: September 2017

AbstractExtant research has suggested that social exclusion could either increase or decrease consumers' subsequent self‐regulatory food choice. From the novel perspective of Active‐Self Account Theory, current research develops a theoretical framework to resolve the conflicting views by introducing individuals' time orientation as an important boundary condition. Our findings from 2 studies demonstrate that (a) when focused on the present, excluded (vs. included) individuals tend to exert less food self‐regulation; and (b) when focused on the future, excluded (vs. included) individuals are inclined to exhibit more food self‐regulation. Moreover, these effects are driven by self‐discipline. We discuss how our findings promote understanding of when and why social exclusion may boost or undermine food self‐regulation, and provide practical implications for food marketing.

Published: September 2017

AbstractUltrathin Pt‐based nanowires are considered as promising electrocatalysts owing to their high atomic utilization efficiency and structural robustness. Moreover, integration of Pt‐based nanowires with graphene oxide (GO) could further increase the electrocatalytic performance, yet remains challenging to date. Herein, for the first time we demonstrate the in situ synthesis of ultrathin PtCu nanowires grown over reduced GO (PtCu‐NWs/rGO) by a one‐pot hydrothermal approach with the aid of amine‐terminated poly(N‐isopropyl acrylamide) (PNIPAM‐NH2). The judicious selection of PNIPAM‐NH2 facilitates the in situ nucleation and anisotropic growth of nanowires on the rGO surface and oriented attachment mechanism accounts for the formation of PtCu ultrathin nanowires. Owing to the synergy between PtCu NWs and rGO support, the PtCu‐NWs/rGO outperforms the rGO supported PtCu nanoparticles (PtCu‐NPs/rGO), PtCu‐NWs, and commercial Pt/C toward the oxygen reduction reaction (ORR) with higher activity and better stability, making it a promising cathodic electrocatalyst for both fuel cells and metal–air cells. Moreover, the present synthetic strategy could inspire the future design of other metal alloy nanowires/carbon hybrid catalysts.

Published: September 2017

AbstractThe pitcher plant has inspired anti‐wetting coatings. However, it is still a challenge to create oleophobic surfaces that repel non‐polar liquids due to their low surface tension. Here we develop an effective strategy to fabricate multifunctional fibrous films by electrospinning polyvinylidene fluoride (PVDF) and polyvinyl acetate (PVAc) polymers. The as‐prepared multifunctional films combined the Janus behavior with hydrophobicity on the upper side and thermally adhesive properties on the lower side. By spraying with lubricant, a pitcher‐plant‐like omniphobic surface has been prepared, which exhibited excellent anti‐wetting properties against water, low surface tension and complex fluids. Furthermore, the transparency of the film has been greatly enhanced after lubrication, which was suitable for glass‐based anti‐fouling materials or coatings.
