Ogallala Aquifer Program: A Catalyst for Research and Education to Sustain the Ogallala Aquifer on the Southern High Plains (2003–2017)
Authors: Brauer David , Devlin Dan , Wagner Kevin , Ballou Mike , Hawkins Dean , Lascano Robert 
Published: December 2017

AbstractThe Ogallala Aquifer Program (OAP) was created in 2003 with support from Congressmen from Kansas and Texas. The OAP is a research‐education consortium seeking solutions from problems arising from declining water availability from the Ogallala Aquifer in western Kansas and the Texas High Plains. The consortium is led by the Agricultural Research Service (ARS) laboratories in Bushland and Lubbock, TX, and the university partners are Kansas State University, Texas A&M AgriLife Research and Extension Service, Texas Tech University, and West Texas A&M University. The OAP has provided over $40 million to support research and education activities. About half of these funds were used to support permanent ARS scientists and ARS hired post‐docs. The other half were used by university scientists to supplement on‐going projects by providing support for supplies, sample analyses, temporary employees, etc. Initially, OAP activities were focused on seven priorities. In 2013, four objectives replaced the original seven priorities. A fifth priority was added in 2017. The current objectives are: 1) Develop and evaluate water management strategies and technologies that could reduce water withdrawals for irrigation by 20% in 2020 compared to 2012; 2) Develop and evaluate management strategies and technologies that would increase the productivity and profitability of dryland cropping systems; 3) Improve the understanding of hydrological and climatic factors that affect water use and agricultural profitability; 4) Determine the impacts of alternative water withdrawal/use policies on the economic viability of the agriculture industry of the Southern Ogallala Aquifer Region; and 5) Develop best management practices for production of high value and alternative crops for both dryland and irrigated systems. The objectives of the program and distribution of resources are decided by an executive committee with a member from each of the four universities, two from ARS, one from Bushland, and the other from Lubbock. Proposed projects that utilize resources from more than one participating institution, leverage existing resources, and address the stated objectives are more likely to be provided support. The impact of the OAP on research directed at agriculture on the High Plains has been recognized by three prestigious awards.

AbstractThe Sustainable Groundwater Management Act (SGMA) is the first comprehensive legislative effort to reform groundwater management in the state of California after years of uncoordinated and voluntary governance of this resource. The objective of this study is to a) describe the SGMA in California, b) describe a method for estimating a water budget, and c) present the implementation of this method for the Ukiah Valley Groundwater Basin (UVGB). An estimated water budget, done on a monthly time step from 1991 to 2015, was developed in order to characterize the UVGB. Results suggest that the groundwater basin is not in overdraft, and that a portion of the Russian River is a gaining river (approximately 18,952 AF/y) from November to June, and a losing river (approximately 393 AF/y) from July to October. Furthermore, lateral groundwater movement is identified through the groundwater mass balance. Based on previous work and the results of this study, the observed later groundwater losses signify connectivity between the UVGB and the Sanel Valley Groundwater Basin (SVGB). Local groundwater managers and users can use this information to inform proposed action plans and monitoring protocols that will allow them to achieve and maintain groundwater sustainability in the UVGB by the year 2040.

AbstractThe Lower Mississippi River Basin (LMRB) is an internationally‐important region of intensive agricultural crop production that relies heavily on the underlying Mississippi River Valley Alluvial Aquifer (MRVAA) for irrigation. Extensive irrigation coupled with the region’s geology have led to significant aquifer decline. The response to the decline has been multi‐faceted. Research related to three responses are highlighted: innovation in rice irrigation, on‐farm reservoirs, and managed aquifer recharge. Irrigated rice grown in Arkansas, which is nearly 50% of annual U.S. rice production, accounts for a significant portion of aquifer withdrawal. As a result, strategies for using less water while maintaining rice yields are being developed. The Rice Stewardship Partnership (RSP) began in 2015 and aims to improve irrigation management in rice lands of the LMRB. Early results from the RSP are presented. Secondly, on‐farm reservoir‐tailwater recovery systems (R‐TWRS) are increasingly used to store abundant surface water in the LMRB. Over 700 R‐TWRS are currently used in rice producing areas of Arkansas. The confining clay layer that overlies the MRVAA in many locations limits rates of aquifer recharge. Locations where the confining layer is thin or non‐existent may provide opportunities for artificial (i.e., managed) recharge. A 10‐m deep excavation pit from a highway project provided an opportunity to measure infiltration rates of the uppermost section of the alluvial aquifer. Findings from this and other studies are used to demonstrate how conservation, off‐season rainfall capture and storage, and managed recharge are being investigated as means to reduce the on‐going decline of the alluvial aquifer that is both economically and ecologically important to the LMRB.
Assessment of job satisfaction in people with intellectual disabilities: Towards best‐practice recommendations
Authors: Kocman Andreas , Weber Germain 
Published: December 2017

BackgroundThe current body of research on job satisfaction of people with intellectual disability is based on highly diverse measures, originating both from the general population and people with intellectual disability. This heterogeneity represents a possible confounder. Best‐practice approaches for the assessment of job satisfaction are hence needed.MethodUsing systematic literature review, job satisfaction measures were identified and analyzed with regard to their applicability for people with intellectual disability. Identified best‐practice measures (JDI/JIGS as well as RSM‐WS) were subsequently applied in the course of a pilot study with 129 employees of sheltered workshops. Comprehension, reliability and validity were assessed.ResultsThe three identified instruments exhibit high reliability and validity. Comprehension was sufficient for JDI and JIGS but better for RSM‐WS.ConclusionsThe JDI/JIGS represent a feasible measures of job satisfaction allowing for comparisons with the general population. In samples with more severe intellectual disabilities, the RSM‐WS is preferable.
A Neofunctionalist Perspective on the ‘European Refugee Crisis’: The Case of the European Border and Coast Guard
Authors: Niemann Arne , Speyer Johanna 
Published: December 2017

AbstractInitial literature on the ‘European refugee crisis’ discerned intergovernmental tendencies in its management. This paper examines whether neofunctionalism may be able to explain a major case of ‘European refugee crisis’ policy‐making, the negotiations on the European Border and Coast Guard regulation. We argue, somewhat counterintuitively, that the theory considerably furthers our respective understanding. The crisis acted as a catalyst exposing the weaknesses of a system that pitted a supranational Schengen against a largely intergovernmental external border regime, notwithstanding a developing Frontex. These dysfunctionalities have been widely fostered by both national and supranational decision‐makers shrinking from the significant economic, political and sunk costs of Schengen disintegration, thus ruling out the possibility for spillback. Additionally, further integration was substantially nurtured by supranational agency, ‘socialized’ national civil servants, transnational NGOs and European business associations.

Published: December 2017

AbstractObjectiveThe aim of this comprehensive review was to assess the effectiveness of erbium lasers in the removal of all ceramic fixed dental prostheses (FDPs).OverviewIndexed databases were searched without language or time restriction up to and including December 2017 using different combinations of the following keywords: “lasers”; “phototherapy”; “crowns”; “prostheses and implants”; “inlays”; “ceramics”; “dental porcelain”; “zirconium”; “removal”; “debonding”; “fixed dental prostheses”; “veneers”; “laminates”; and “fixed bridge.” All levels of available evidence including experimental studies, case reports and case series were included. Six clinical studies reporting a total of 13 cases and 6 experimental studies were included. Results from all studies showed that erbium lasers are effective reducing the shear bond strengths of all ceramic FDPs, in terms of easy removal of the restorations with none or minimal damage to teeth or ceramic surfaces.ConclusionLaser‐assisted removal of all ceramic FDPs is a promising treatment protocol. Further well‐designed controlled clinical trials and longitudinal prospective studies are needed to determine the precise laser parameters and duration of irradiation that could be used for removal of ceramic restorations with varying thicknesses.Clinical significanceBenefits of lasers over mechanical instrumentation for crown removal encompass efficient restoration retrievability without restoration or teeth surfaces damages; and relatively easier and time effective procedure with no prerequisite for anesthetic agents. It is however imperative for clinicians to be well‐trained and exhibit adequate knowledge regarding recommended power settings and laser‐safety parameters with reference to interactions between light and different tissues and ceramics.

Published: December 2017

AbstractTo explore the best method for non‐destructively and accurately quantitative detection of mixed pesticide residue in vegetables, the mixed pesticide (fenvalerate and dimethoate) of lettuce leaves was used as the research object detected by hyperspectral technique. The hyperspectral data was preprocessed using standard normalized variable. Then two different kinds of characteristic wavelengths were selected using competitive adaptive reweighed sampling (CARS) and random forest‐recursive feature elimination (RF‐RFE), respectively. The least squares support vector regression (LSSVR) model results of predicting fenvalerate and dimethoate showed that the CARS‐screened wavelengths had the best modeling results for fenvalerate with
of 0.8203 and RMSEP of 0.0222, and the RF‐RFE‐screened wavelengths had the best results for dimethoate with
of 0.8712 and RMSEP of 0.0186. To simplify the calibration model, successive projections algorithm (SPA) was used for the second selection of characteristic wavelengths. Finally, the CARS‐SPA‐LSSVR model for predicting fenvalerate achieved the accuracy with
of 0.8890 and RMSEP of 0.0182, RF‐RFE‐SPA‐LSSVR model for predicting dimethoate with
of 0.9386 and RMSEP of 0.0077. Thus, hyperspectral technique can be applied to quantitatively detect the mixed pesticide residue of lettuce leaves.Practical applicationsLettuce leaves can be used for raw food, and lettuce leaves with mixed pesticide residues is more likely to bring harm to people's health. Traditional methods of detecting pesticide residues are time‐consuming and destructive to samples, so they cannot meet the requirement of modern agriculture. Whereas, hyperspectral imaging technology is a new rapidly growing method which integrates spectroscopic and imaging techniques in one system for providing both spectral and spatial information simultaneously, of which the spectral information can detect the physical structure and chemical composition of unknown samples. Therefore, the hyperspectral technique is a fast and nondestructive detecting method, and this study showed it is feasible for quantitative detection of the mixed pesticide residue of lettuce leaves.
Food safety practices, levels of knowledge, and problems of dairy companies in Turkey
Authors: Kirdar Seval Sevgi 
Published: December 2017

AbstractMilk contains a large number of essential nutrients that should be consumed at every stage of human life. As a subsector, the dairy industry is extremely important to the national economy. The dairy industry constitutes 16% of the output of the food industry in Turkey. Burdur is one of the major cities in Turkey in terms of the dairy industry. Burdur province has significant potential both in terms of dairy farming and the processing industry. Burdur province produces 258,000 tons of milk annually. There are 16 milk processing plants in the province. The total capacity of these enterprises is 184,807 tons per year, but capacity use is only 69,480 tons per year. In addition, milk powder and whey powder are available at only one processing facility; the capacity of this facility is 4,554 tons per year. Although the province's milk processing capacity is 68.44%, only 26.9% of the milk produced in the province is traded in the province; 73.1% is processed outside the province.Practical applicationsIn this study, we examine the general characteristics of the 13 operating dairies in Burdur province. We used questionnaires to determine problems and solutions concerning food safety, the level of information on food safety among managers, resources, and current practices. This study used an in‐depth interview method to survey business managers and employees. We surveyed managers and employees concerning their knowledge of food security, sources of information, and problems and solutions.

SummaryThere is little evidence of sensation in individuals with diabetes mellitus (DM) in the dental research field. We investigated whether pain thresholds (PTs) differ between individuals with and without DM (non‐DM; NDM). To this end, we assessed whether PTs obtained from the oral cavity, hands, and feet differed from each other and across groups, and whether PTs differed for the three current frequencies used for testing (2000 Hz, 250 Hz, and 5 Hz). Pain threshold measurements were obtained from the oral mucosa and the tips of the fingers and toes of 56 volunteers, including 21 individuals with DM (12 men and 9 women, average age: 72.1 ± 4.7 years) and 35 NDM individuals (17 males and 18 females, average age: 51.2 ± 23.9 years) using the Neurometer CPT/C® device to deliver electrical stimulation. A single operator obtained PT measurements from around the left greater palatine foramen and from the tip of the left first finger and of the left great toe. Individuals with DM had significantly lower PT values than those without DM. The PT values for the oral cavity, hands, and feet differed significantly from each other (foot > hand, foot > oral cavity, hand > oral cavity). Moreover, there was a significant difference in the PT values for 5 Hz and 2000 Hz, as well as for 250 Hz and 2000 Hz. This study concluded that PT values derived from DM participants are lower than those from NDM participants, although PT measurements varied across regions and with current frequency.
Joint optimization of cluster number and abundance transformation for obtaining effective vegetation classifications

Published: December 2017

AbstractQuestionIs it possible to determine which combination of cluster number and taxon abundance transformation would produce the most effective classification of vegetation data? What is the effect of changing cluster number and taxon abundance weighting (applied simultaneously) on the stability and biological interpretation of vegetation classifications?LocalityEurope, Western Australia, simulated data.MethodsReal data sets representing Hungarian sub‐montane grasslands, European wetlands, and Western Australian kwongan vegetation, as well as simulated data sets were used. The data sets were classified using the partitioning around medoids method. We generated classification solutions by gradually changing the transformation exponent applied to the species projected covers and the number of clusters. The effectiveness of each classification was assessed with a stability index. This index is based on bootstrap resampling of the original data set with subsequent elimination of duplicates. The vegetation types delimited by the most stable classification were compared with other classifications obtained at local maxima of the stability values. The effect of changing the transformation power exponent on the number of clusters, indexed according to their stability, was evaluated.ResultsThe optimal number of clusters varied with the power exponent in all cases, both with real and simulated data sets. With the real data sets, optimal cluster numbers obtained with different data transformations recovered interpretable biological patterns. Using the simulated data, the optima of stability values identified the simulated number of clusters correctly in most cases.ConclusionsWith changing the settings of data transformation and the number of clusters, classifications of different stability can be produced. Highly stable classifications can be obtained from different settings for cluster number and data transformation. Despite similarly high stability, such classifications may reveal contrasting biological patterns, thus suggesting different interpretations. We suggest testing a wide range of available combinations to find the parameters resulting in the most effective classifications.
Sedimentation limits the erosion rate of a bioeroding sponge
Authors: Marlow Joseph , Smith David , Werorilang Shinta , Bell James 
Published: December 2017

AbstractCoral reefs are increasingly threatened by anthropogenic disturbances and consequently coral cover and complexity are declining globally. However, bioeroding sponges, which are the principal agents of internal bioerosion on many coral reefs, are increasing in abundance on some degraded reefs, tipping them towards net carbonate erosion. The aim of this study was to identify the environmental factors that drive the erosion rates of the common Indonesian bioeroding sponge Spheciospongia cf. vagabunda. Sponge explants were attached to limestone blocks and deployed across seven sites characterized by different environmental conditions in the UNESCO Wakatobi Biosphere Reserve in Indonesia. Average bioerosion rates were 12.0 kg m−2 sponge tissue year−1 (±0.87 SE), and were negatively correlated with depth of settled sediment (r = −.717, p < .01) and showed weak positive correlation with water movement (r = .485, p = .012). Our results suggest that although bioeroding sponges may generally benefit from coral reef degradation, bioerosion rates may be reduced on reefs that are impacted by high sedimentation, which is a common regional stressor in the South‐East Asian Indo‐Pacific.
Harbor seal use of glacier ice and terrestrial haul‐outs in the Kenai Fjords, Alaska
Authors: Hoover‐Miller Anne , Armato Peter 
Published: December 2017

AbstractHarbor seals, Phoca vitulina, use diverse haul‐out substrates including ice calved by tidewater glaciers. Numbers of seals at glacial and terrestrial haul‐outs on the southeastern Kenai Peninsula, Alaska, were assessed using aerial, vessel, and video surveys. Mean annual abundance at glacial and terrestrial haul‐outs differed temporally. From 2004 to 2011, numbers of seals counted during the molt increased 5.4%/yr at glacial haul‐outs and 9%/yr at terrestrial haul‐outs while numbers of pups increased 5.0%/yr at glacial sites and 1.5%/yr at terrestrial sites. Numbers of seals without pups counted during pupping increased 7.96%/yr at glacial sites and 5.1%/yr at terrestrial sites. Results indicate that pupping and molting locations are not equivalent and population monitoring during the molt does not necessarily reflect habitat association of pupping seals. Ratios of pups to total seals counted during pupping and the subsequent molt were used to contrast habitat use. Low proportions of pups at terrestrial haul‐outs, relative to most glacial haul‐outs, indicate an overall preference for pupping in glacial haul‐outs. High proportions of pups at most glacial sites (during pupping and molting) suggest reduced use of tidewater glacier habitats by nonbreeders and molting seals. Results suggest more seals associate with glacial haul‐outs than currently estimated.
Introduction: The state and historic buildings: preserving ‘the national past’
Authors: Thatcher Mark 
Published: December 2017

AbstractHistoric buildings are important in nationalism through their roles in building and reinforcing national identity. As part of the expanding ‘heritage industry’, they are also of growing economic and political importance. Despite their physical existence, historic buildings are ‘created’ – they must be constructed as ‘historic’ through processes of choice and the attachment of significance. The state can perform these functions through policies that define and select buildings for protection, by ownership and funding, and by its uses of buildings for nationalistic purposes. Yet state actors can have good reasons – nationalistic and economic – to destroy or fail to preserve historic buildings. The paper examines why, when and how state actors pursue policies to protect historic buildings. It offers arguments about patterns of state action that part of state strategies to promote national identity and cultural nationalism.
State production of cultural nationalism: political leaders and preservation policies for historic buildings in France and Italy
Authors: Thatcher Mark 
Published: December 2017

AbstractAlthough cultural and political nationalism have often been treated as separate, recent studies argue that they are linked because the state produces policies such as promotion of cultural heritage to further nation building. The article examines the conditions that favour national political leaders adopting policies to protect historic buildings for aims of political nationalism. It compares France and Italy, focusing on the period after 1870. It finds that in both countries, national political leaders have introduced extensive protection of historic buildings when faced with major challenges such as war, regime change or pressures from localism or supporters of cultural nationalism as part of wider strategies to build and reinforce the nation state. But Italy extended protection earlier and more deeply than France, suggesting in a later nation state with strong inherited cultural nationalism but major political weaknesses and, national political leaders may introduce earlier, more far‐reaching and more layered legal protection than in states created earlier and with fewer weaknesses.
