Assessing Outputs, Outcomes, and Barriers in Collaborative Water Governance: A Case Study
Authors: Koebele Elizabeth A. 
Published: August 2015

AbstractAs freshwater supplies become increasingly threatened by overuse, pollution, and changes in climate, governing bodies have begun to recognize the urgent need for flexible, sustainable solutions to water use and management. Collaborative governance of water resources has arisen as a widespread strategy to develop such solutions in a way that integrates diverse stakeholder needs and works to create consensus‐driven management actions. Directly linking the outputs of collaborative processes to improved water sustainability is difficult even on a local scale. However, examining diverse collaborative governance processes, particularly the outputs and outcomes produced and barriers faced, is necessary as these processes continue to flourish at a multitude of scales and settings. In 2005, the state of Colorado initiated a collaborative governance process to assess its existing water resources and future water needs; the information gathered through this endeavor is now being used to inform the creation of Colorado's first statewide water plan. Using data from 28 in‐depth interviews with key participants in this process, this paper highlights not only what outputs and outcomes may be produced through a high‐stakes collaborative process, but also what barriers exist to producing desired outputs (and therefore, consequent outcomes). Gaining a better understanding of outputs, outcomes, and barriers within a statewide collaborative water governance process can provide insight into improving future decision‐making processes and evaluations of those processes in a variety of natural resource arenas.

AbstractThe soon‐to‐be completed Grand Ethiopian Renaissance Dam (GERD), which will be the largest hydroelectric power plant and among the largest reservoirs in Africa, has highlighted the need for expanding traditional integrated water resources management to better include the cultural, social, and political complexities of large water infrastructure in development projects. The GERD will store a maximum of 74 billion cubic meters of water corresponding to approximately the average annual outflow of the Nile from the Aswan high dam. Undoubtedly, the GERD will be vital for energy production and a key factor for food production, economic development, and poverty reduction in Ethiopia and the Nile Basin. However, the GERD is also a political statement that in one stroke has re‐written the hydropolitical map of the Nile Basin. The GERD has become a symbol of Ethiopian nationalism or “renaissance” (hidase in Amharic). A contrasting concept to nationalism is hydrosolidarity. This concept has been put forward to better stress equitable use of water in international water management challenges that would lead to sustainable socioeconomic development. We use the opposing notions of nationalism and hydrosolidarity at three different scales, everyday politics, state policies, and interstate and global politics to analyse some aspects of the new hydropolitical map of the Nile Basin. We argue that nationalism and national interests are not necessarily negative standpoints but that there may instead be a meeting point where regional and national interests join with hydrosolidarity principles. We believe that this meeting point can maximize not only the common good, but also the good from a national interest point of view. For this, it is important not increase collaboration instead of being locked in to the historical narrative of nationalistic culture and historical discourse. This would benefit and improve future sustainability.

Yb:(LaY)2O3 ceramic samples have been sintered to almost full density in a fast microwave heating process with zero hold time. Rapid densification is observed at heating rates ranging from 50°C to 2400°C/min. The estimated value of the power absorbed in the materials per unit volume is from 10 to 400 W/cm3, which is similar to the processes of flash sintering under an applied dc/ac voltage. The microstructure of the sintered samples exhibits traces of a liquid‐like intergranular phase. The observed flash microwave sintering effect is associated with both preferential microwave absorption and enhanced mass transport within the softened grain boundaries arising due to an elevated concentration of defects and impurities therein. The volumetric nature of microwave heating gives rise to thermal stresses which can act as an additional driving force for sintering. The advantage of the microwave flash sintering process is that no electrodes are needed to supply the power to the articles undergoing sintering.

Published: August 2015

Rare‐earth containing phosphors have been widely applied in lighting and display fields in the past century. Lower cost rare‐earth free phosphors with high performance are highly desired driven by the exhaustion of rare earth resources and the requirement of cheaper production. Herein, Cu+ ions doped tetracalcium phosphate (TTCP) yellow emitting phosphors with quantum yield of 21% are exploited. Particularly, ultra‐broad band emission with a full width at half maximum (FWHM) about 200 nm throughout almost entire visible light region is observed for TTCP: Cu+ phosphors, evidencing its promising application in high color rendering index (CRI) lighting source. White light emission with CRI value about 94.3 is generated by combining this TTCP: Cu+ phosphor with commercial BaMgAl10O17: Eu2+ blue phosphor, exhibiting superiority over the traditional trichromatic phosphors. Therefore, we predict great potential application for this cheaper rare‐earth free TTCP: Cu+ phosphor in high CRI lighting sources.

Published: August 2015

The crystal structure and microwave dielectric properties of a novel low‐firing compound Li2Mg2W2O9 were investigated in this study. The phase purity and crystal structure were investigated using X‐ray diffraction analyses and Rietveld refinement. The best microwave dielectric properties of the ceramic with a low permittivity (εr) ~11.5, a quality factor (Q × f) ~31 900 GHz (at 10.76 GHz) and a temperature coefficient of the resonant frequency (τf) ~ −66.0 ppm/°C were obtained at the optimum sintering temperature (920°C). CaTiO3 was added into the Li2Mg2W2O9 ceramic to obtain a near zero τf, and 0.93Li2Mg2W2O9–0.07CaTiO3 ceramic exhibited improved microwave dielectric properties with a near‐zero τf ~ −1.3 ppm/°C, a εr ~21.6, a high Qu × f value ~20 657 GHz. The low sintering temperature and favorable microwave dielectric properties make it a promising candidate for LTCC applications.

Published: August 2015

Transparent (Y0.98−xTb0.02Eux)2O3 (x = 0–0.04) ceramics with color‐tailorable emission have been successfully fabricated by vacuum sintering at the relatively low temperature of 1700°C for 4 h. These ceramics have the in‐line transmittances of ~73%–76% at 613 nm, the wavelength of Eu3+ emission (the 5D0→7F2 transition). Thermodynamic calculation indicates that the Tb4+ ions in the starting oxide powder can essentially be reduced to Tb3+ under ~10−3 Pa (the pressure for vacuum sintering) when the temperature is above ~394°C. The photoluminescence excitation (PLE) spectra of the transparent (Y0.98−xTb0.02Eux)2O3 ceramics exhibit one spin‐forbidden (high‐spin, HS) band at ~323 nm and two spin‐allowed (low‐spin, LS) bands at ~303 and 281 nm. Improved emissions were observed for both Eu3+ and Tb3+ by varying the excitation wavelength from 270 to 323 nm, without notably changing the color coordinates of the whole emission. The transparent (Y0.98Tb0.02)2O3 ceramic exhibits the typical green emission of Tb3+ at 544 nm (the 5D4→7F5 transition). With increasing Eu3+ incorporation, the emission color of the (Y0.98−xTb0.02Eux)2O3 ceramics can be precisely tailored from yellowish‐green to reddish‐orange via the effective energy transfer from Tb3+ to Eu3+ under the excitation with the peak wavelength of the HS band. At the maximum Eu3+ emission intensity (x = 0.02), the ceramic shows a high energy‐transfer efficiency of ~85.3%. The fluorescence lifetimes of both the 544 nm Tb3+ and 613 nm Eu3+ emissions were found to decrease with increasing Eu3+ concentration.

Published: August 2015

Pressure‐less spark plasma sintering (SPS) is a new approach during which rapid densification of ceramic nanopowder green bodies is accompanied by rapid grain growth. Although the origin of this phenomenon has not yet been fully understood significant, difference in grain growth between pressure‐less and pressure‐assisted SPS was expected. In this work 3Y‐TZP nanopowder with average particle size of 12 nm was consolidated using two‐step approach: (1) at an intermediate temperature (600°C to 1000°C) SPS warm pressing followed by (2) high temperature (1400°C to 1600°C) pressure‐less SPS. The standard one step pressure‐assisted SPS experiments were quoted as references. Rapid grain growth was observed during both pressure‐less and standard SPS. The samples prepared by both approaches at the same sintering temperature (1400°C–1600°C) achieved identical grain size and grain size distribution, if large pores were eliminated in early stage by SPS warm pressing. The electric current, electromagnetic field, and mechanical pressure is proven to have a negligible direct influence on grain growth in 3Y‐TZP ceramics at temperatures above 1000°C under standard SPS conditions.

Bismuth ferrite, BiFeO3, is an important multiferroic material that has attracted remarkable attention for potential applications in functional devices. While thin films of BiFeO3 are attractive for applications in nanoelectronics, bulk polycrystalline BiFeO3 has great potential as a lead‐free and/or high‐temperature actuator material. However, the actuation mechanisms in bulk BiFeO3 are still to be resolved. Here we report the microscopic origin of electric‐field‐induced strain in bulk BiFeO3 ceramic by means of in situ high‐energy X‐ray diffraction. Quantification of intrinsic lattice strain and extrinsic domain switching strain from diffraction data showed that the strain response in rhombohedral bulk BiFeO3 is primarily due to non‐180° ferroelectric domain switching, with no observable change in the phase symmetry, up to the maximum field used in the study. The origin of strain thus differs from the strain mechanism previously shown in thin film BiFeO3, which gives a similar strain/field ratio as rhombohedral bulk BiFeO3. A strong post‐poling relaxation of switched non‐180° ferroelectric domains has been observed and hypothesized to be due to intergranular residual stresses with a possible contribution from the conductive nature of the domain walls in BiFeO3 ceramics.
TNF‐α: a treatment target or cause of sarcoidosis?
Authors: Amber K.T. , Bloom R. , Mrowietz U. , Hertl M. 
Published: August 2015

AbstractSarcoidosis is a systemic granulomatous disease that affects numerous organs, commonly manifesting at the lungs and skin. While corticosteroids remain the first line of treatment, tumour necrosis factor alpha (TNF‐α) inhibitors have been investigated as one potential steroid sparing treatment for sarcoidosis. TNF‐α is one of many components involved in the formation of granulomas in sarcoidosis. While there have been larger scale studies of biologic TNF‐α inhibition in systemic sarcoidosis, studies in cutaneous disease are limited. Paradoxically, in some patients treated with biologic TNF‐α inhibitors for other diseases, treatment can induce the development of sarcoidosis. In the light of this complexity, we discuss the role of TNF‐α in granuloma formation, the therapeutic role of TNF‐α inhibition and immunologic abnormalities following treatment with these TNF‐α inhibitors including drug‐specific alterations involving interferon‐γ, lymphotoxin‐α, TNF receptor 2 (TNFR2) and T‐regulatory cells.

AbstractComposite scales such as the Total Neuropathy Score clinical version (TNSc©) have been widely used to measure neurological impairment in a standardized manner but they have been criticized due to their ordinal setting having no fixed unit. This study aims to improve impairment assessment in patients with chemotherapy‐induced peripheral neuropathy (CIPN) by subjecting TNSc© records to Rasch analyses. In particular, we wanted to investigate the influence of factors affecting the use of the TNSc© in clinical practice. TNSc© has 7 domains (sensory, motor, autonomic, pin‐prick, vibration, strength, and deep tendon reflexes [DTR]) each being scored 0–4. Data obtained in 281 patients with stable CIPN were subjected to Rasch analyses to determine the fit to the model. The TNSc© did not meet Rasch model's expectations primarily because of misfit statistics in autonomic and DTR domains. Removing these two, acceptable model fit and uni‐dimensionality were obtained. However, disordered thresholds (vibration and strength) and item bias (mainly cultural) were still seen, but these findings were kept to balance the assessment range of the Rasch‐Transformed TNSc© (RT‐TNSc©). Acceptable reliability findings were also obtained. A 5‐domains RT‐TNSc© may be a more proper assessment tool in patients with CIPN. Future studies are needed to examine its responsive properties.

AbstractWe studied the clinical, electrophysiological, and pathological features, outcome, and frequency of anti‐tumor necrosis factor alpha (a‐TNF) medications‐induced neuropathies (ATIN) in patients with inflammatory disorders. Of 2,017 patients treated with a‐TNF medication, 12 patients met our inclusion criteria for a prevalence of 0.60% and an incidence of 0.4 cases per 1,000 person‐years. The median time from a‐TNF medication treatment to ATIN was 16.8 months (range 2–60 months). Six patients had focal or multifocal peripheral neuropathies. The other six had generalized neuropathies. For all, a‐TNF medication was stopped. Seven patients received immunoglobulin infusions. ATIN outcome was favorable in all but one patient. ATINs are rare and heterogeneous neuropathies. In 10 patients, the neuropathy was “inflammatory”, suggesting that it could be due to systemic pro‐inflammatory effects of a‐TNF agents.
Perspective: New Service Development: How the Field Developed, Its Current Status and Recommendations for Moving the Field Forward

Published: August 2015

New service development (NSD) is a growing innovation discipline. Despite the growth of articles about NSD, several authors have criticized the lack of attention paid to NSD, compared with new product development (NPD), and the lack of consensus across NSD findings. At the same time, others have proclaimed that NSD is a sophisticated, mature field of research. This paper tries to resolve these issues by analyzing 230 empirical articles on NSD, published over a period of 30 years. It investigates the content of NSD research articles, the authors contributing to the field, and the research methodologies employed. It finds that, despite its growing popularity, the field has not moved forward substantively. NSD is a subject specialty but lacks an “invisible college” of researchers addressing the topic. This has resulted in a body of research that fails to provide managers with consistent answers to basic questions about how to most effectively manage NSD processes.One of the main causes for the lack of coherence in the knowledge on this topic may stem from the fact that, rather than initially approaching research in the domain without ingoing bias and using grounded theory approaches to create initial understanding, many of the early researchers applied the concepts, frameworks, and methods used to understand NPD to the NSD domain. To correct this problem, it is proposed that the field of NSD needs to move forward in a significantly different manner. This paper provides several recommendations for attracting more academics to the field, elevating the visibility and status of NSD as a research domain, and also presents a research agenda that may help reorient future research in this area so that a more complete and coherent body of knowledge is generated that both advances the field and helps practitioners manage NSD more effectively and efficiently.

Published: August 2015

SummaryTo determine whether non‐dreamers do not produce dreams or do not recall them, subjects were identified with no dream recall with dreamlike behaviours during rapid eye movement sleep behaviour disorder, which is typically characterised by dream‐enacting behaviours congruent with sleep mentation. All consecutive patients with idiopathic rapid eye movement sleep behaviour disorder or rapid eye movement sleep behaviour disorder associated with Parkinson's disease who underwent a video‐polysomnography were interviewed regarding the presence or absence of dream recall, retrospectively or upon spontaneous arousals. The patients with no dream recall for at least 10 years, and never‐ever recallers were compared with dream recallers with rapid eye movement sleep behaviour disorder regarding their clinical, cognitive and sleep features. Of the 289 patients with rapid eye movement sleep behaviour disorder, eight (2.8%) patients had no dream recall, including four (1.4%) patients who had never ever recalled dreams, and four patients who had no dream recall for 10–56 years. All non‐recallers exhibited, daily or almost nightly, several complex, scenic and dreamlike behaviours and speeches, which were also observed during rapid eye movement sleep on video‐polysomnography (arguing, fighting and speaking). They did not recall a dream following sudden awakenings from rapid eye movement sleep. These eight non‐recallers with rapid eye movement sleep behaviour disorder did not differ in terms of cognition, clinical, treatment or sleep measures from the 17 dreamers with rapid eye movement sleep behaviour disorder matched for age, sex and disease. The scenic dreamlike behaviours reported and observed during rapid eye movement sleep in the rare non‐recallers with rapid eye movement sleep behaviour disorder (even in the never‐ever recallers) provide strong evidence that non‐recallers produce dreams, but do not recall them. Rapid eye movement sleep behaviour disorder provides a new model to evaluate cognitive processing during dreaming and subsequent recall.

SummaryHepatitis C virus (HCV) causes not only liver damage in certain patients but can also lead to neuropsychiatric symptoms. Previous studies have shown that the type 4 allele of the gene for apolipoprotein E (APOE) is strongly protective against HCV‐induced damage in liver. In this study, we have investigated the possibility that APOE genotype is involved in the action of HCV in brain. One hundred HCV‐infected patients with mild liver disease underwent a neurological examination and a comprehensive psychometric testing of attention and memory function. In addition, patients completed questionnaires for the assessment of fatigue, health‐related quality of life and mood disturbances. Apolipoprotein E gene genotyping was carried out on saliva using buccal swabs. The APOE‐ε4 allele frequency was significantly lower in patients with an impairment of working memory, compared to those with a normal working memory test result (P = 0.003). A lower APOE‐ε4 allele frequency was also observed in patients with definitely altered attention ability (P = 0.008), but here, the P‐value missed the level of significance after application of the Bonferroni correction. Our data suggest that the APOE‐ε4 allele is protective against attention deficit and especially against poor working memory in HCV‐infected subjects with mild liver disease. Considering the role of apolipoprotein E in the life cycle of the virus, the findings shed interesting new light upon possible pathomechanisms behind the development of neuropsychiatric symptoms in hepatitis C infection.
