Strauss and Hofmannsthal's Arabella and the Resacralization of the Operatic Tradition
Authors: Brooks Marc 
Published: May 2015

Abstract
The obvious debt that Strauss's operas owe to Wagner often led early critics to view their conspicuous lack of spiritual depth as an unintentional failure. Recent commentators such as Charles Youmans, Leon Botstein, and Michael Walter have rightly characterized this feature as a conscious Nietzschean strategy calculated to avoid or ironize metaphysical tropes. Following the critique of the concept of “secularization” by Jürgen Habermas and Charles Taylor, however, I wish to complicate this newer interpretation by arguing that Strauss's operas do not represent the point in music history when German music threw off its pretentions to Kunstreligion, but mark yet another point of “re-sacralization”—a term I borrow from Simon Critchley's Faith of the Faithless (2012).
The Wagner-indebted music in Arabella (1933)—an opera given much less critical attention than it deserves—certainly never gestures toward any transcendent truth beyond the physical confines of what is presented. Nevertheless, I argue, a sacred economy still operates in the opera whereby certain aspects of the immanent stage-world are figured as “sacred” and others as “profane.” It is possible to trace the influence of the operas Tannhäuser and Parsifal on Arabella, specifically in the harmonic, rhythmic, and timbral techniques Wagner used to mark certain suprahuman forces as possessing a transcendent aura. The music of Arabella uses moderated versions of these techniques to redistribute the same sacred status onto different aspects of material and psychological reality.

The association between rotating shift work and increased occupational stress in nurses: Pei‐Chen Lin, et al. Department of Public Health, College of Health Sciences, Kaohsiung Medical University, TaiwanPurposeThe aim of this study was to investigate whether rotating shift work increases occupational stress in nurses.MethodsThis study measured shift work scheduling and occupational stress by using the Effort‐Reward Imbalance model with self‐reported questionnaires in a sample of 654 female nurses.ResultsOvercommitment risk was higher in nurses who worked rotating shifts than in those who worked day/non‐night shifts (OR, 2.16; 95% CI, 1.03−4.66). However, an effort/reward imbalance was not directly associated with work schedules (OR, 1.88; 95% CI, 0.87−4.35). Among nurses working rotation rotating shifts, those who had 2 days off after their most recent night shifts showed an alleviated risk of overcommitment (OR, 0.52; 95% CI, 0.32−0.82), but those who had worked for at least one series of 7 consecutive work days per month had an increased risk of effort/reward imbalance (OR, 2.75; 95% CI, 1.69−4.48). Additionally, those who had little or no participation in planning working hours and shift scheduling and worked overtime at least three times per week during the preceding 2 months tended to have high stress.ConclusionsThe nurses who worked rotating shifts tended to experience work‐related stress, but their stress levels improved if they had at least 2 days off after their most recent night shift and if they were not scheduled to work 7 consecutive days. These empirical data can be used to optimize work schedules for nurses to alleviate work stress.
Biochemical composition of the fluid of ovarian cysts and pre-ovulatory follicles compared to the serum in sows
Authors: Stankiewicz T. 
Published: May 2015

SummaryObjective: The objective of this study was to compare the biochemical composition of follicular cysts, pre-ovulatory follicles and serum in sows. Material and methods: The research involved multiparous sows (cysts-bearing sows, n = 21; non-cysts-bearing sows, n = 22). Concentration of glucose, protein, cholesterol (CHOL), high-density lipoprotein (HDL), low-density lipoprotein (LDL) and triacylglycerol (TAG) in the samples was determined. Results: Glucose concentration in serum was higher than in cysts and follicles (p < 0.01) and glucose concentration in cysts was higher than in follicles (p < 0.01). Differences were also observed between the concentration of glucose in serum of cysts-bearing and non-cysts-bearing sows (p < 0.01). Protein concentration in cysts and follicles was lower than in serum (p < 0.01). Concentration of cholesterol in the serum of cysts-bearing sows and non-cysts-bearing sows was higher than the one in cysts and follicles (p < 0.01). Cholesterol concentration in the serum of cysts-bearing sows was higher than the one in non-cysts-bearing sows (p < 0.01). Concentration of HDL in serum of both cysts-bearing and non-cysts-bearing sows was also higher than the one in cysts and follicles (p < 0.01). Cysts-bearing sows had a higher concentration of HDL in the serum than non-cysts-bearing sows. Differences were also observed between the concentration of HDL in cysts and the one in follicles (p < 0.05). LDL was determined not to be present in either cysts or pre-ovulatory follicles. TAG concentration in the serum of cysts-bearing sows was higher than the one in the serum of non-cysts-bearing sows (p < 0.05). Differences were also detected between the TAG concentrations in cysts and in follicles (p < 0.01). Conclusion: The differences in the biochemical composition of the fluid in follicular cysts and pre-ovulatory follicles point to the variable intensification of the course of metabolic processes in pathological and physiological ovarian structures.

Published: May 2015

Objectives This cross-sectional study sought to assess bone formation and spontaneous tooth eruption in a cohort of 25 consecutive patients aged 6 to 11 years who underwent primary gingivoperiosteoplasty by the Collares technique. Design Cross-sectional study assessing bone formation in the cleft area using a within-group time series design. Setting Hospital de Clínicas de Porto Alegre (HCPA), a tertiary hospital in Brazil. Patients Twenty-five patients with nonsyndromic, complete unilateral cleft lip and palate, no comorbidities, and unerupted permanent canines. Intervention Cheiloplasty was performed by means of the Millard II technique, with the addition of a triangle at the mucocutaneous junction, vomer flap nasal floor closure, and wide subperiosteal elevation, followed by gingivoperiosteoplasty by the Collares technique. Main Outcome Measures Cone-beam computed tomography was used to assess treatment effect. In a novel method, software was used to obtain two three-dimensional reconstructions, one each of the cleft and noncleft sides, enabling quantitative comparison of bone presence in the alveolar defect area. Results Of the 25 patients, 24 achieved bone bridge formation. The cleft side had 75.1% (67.9%-82.3%) of the bone volume, 70.5% (53.1%-87.9%) of the height, and 63.3% (44.1%-82.5%) of the width of the noncleft side. Bone formation was 17.28% lower in patients with lateral incisor agenesis. Conclusion Collares gingivoperiosteoplasty performed well as a technique for alveolar repair in patients with cleft lip and palate, allowing spontaneous eruption of deciduous and permanent lateral incisors through the bone bridge created.
Analysts, Macroeconomic News, and the Benefit of Active In-House Economists
Authors: Hugon Artur , Kumar Alok , Lin An-Ping 
Published: May 2015

ABSTRACT
Although macroeconomic news has a major impact on corporate earnings, anecdotal evidence suggests that financial analyst research is inefficient with respect to such news. Examining analysts' earnings research, we find that they underreact to negative macroeconomic news. Analysts are not all equal, though, as analysts employed at the same firm as an active macroeconomist underreact much less. We find that the benefit of analyst access to an economist is concentrated in firms that are high in cyclicality relative to their industry, high in cyclicality in general, and that are smaller in size. In addition, analysts who are exposed to more accurate or award-winning in-house macroeconomists benefit more. Investors appear to recognize the advantage of access to macroeconomists, reacting more strongly to these analysts' forecast revisions. Overall, our results suggest that the presence of an active in-house macroeconomist improves the efficiency and credibility of analyst research.

Concession, Contention, and Accountability in Auditor-Client Negotiations
Authors: Bergner Jason M. , Peffer Sean A. , Ramsay Robert J. 
Published: May 2015

ABSTRACT
This study investigates how tactics employed by a client during negotiations impact experienced auditors' propensity to waive material adjustments and whether the salience of a strict concurring partner review affects the decision to waive. Different psychological theories predict that auditors may either become more contentious or more concessionary when facing a contentious client. Our results suggest that auditors are more likely to waive material adjustments when clients use contending tactics, but not concessionary tactics. However, we also find that making a strict concurring partner review salient reduces this propensity. Further, we find that a theory not previously applied to this line of research, the level-of-aspiration theory, may predict how auditors react. These results offer additional insights into auditor-client negotiations and reveal that existing quality controls can influence these negotiations.
Genetic Diversity and Spatial Genetic Structure of Stellaria Holostea Populations from Urban Forest Islands
Authors: Wodkiewicz Maciej , Gruszczyńska Bożenna 
Published: May 2015

Abstract
Stellaria holostea is a clonal herb highly confined to well-established deciduous forests. This study examined whether its genetic diversity and spatial genetic organization in urban forest islands is similar to the values from well-established populations outside urban landscape. We studied four populations in Warsaw and two populations from well preserved forests outside the city. Genetic diversity was greater in populations from well-preserved forests than from forests heavily exploited in the past. High clonal diversity indices indicate that the studied populations did not lose the ability to reproduce sexually. The small populations in urban forests differed from the remaining sites in spatial organization. High overall FST (0.24) and the lack of correlation between genetic and geographic distance between the studied populations indicate limited gene flow. Urban forests may be of great value for conservation of S. holostea and other ancient forest species as they may still harbor substantial genetic variability despite their isolation.
The Role of Jasmonates in the Formation of a Compound of Chalcones and Flavans with Phytoalexin-Like Properties in Mechanically Wounded Scales of Hippeastrum × Hybr. Bulbs

Published: May 2015

Abstract
Mechanical damage to scales of Hippeastrum × hybr. bulbs leads to the formation of phytoalexin-like compounds which redden the wounded tissue. The reaction is accompanied by an increase in methyl jasmonate (JA-Me). Applying 2-(4-isobutylphenyl) propionic acid, a jasmonate biosynthesis inhibitor, decreases the level of endogenous jasmonates and decreases the plant's ability to produce the red pigment. Experimental results indicate that jasmonates are involved in the defense response to wounding in Hippeastrum, which is manifested in the formation of red pigment, a compound of chalcones and flavans with phytoalexin-like properties.

Published: May 2015

Abstract
Water level fluctuation and inorganic nitrogen enrichment are two serious problems caused by anthropogenic disturbances in aquatic ecosystems. They cause resource fluctuation and thus might influence the invasive-ness of alien plants. Alternanthera philoxeroides is an amphibious and widespread clonal plant which exhibits significant invasiveness. This experimental study examined the plant's morphological traits under different nitrogen concentrations and water levels. The responses of A. philoxeroides to water levels and nitrogen concentrations were similar for both land-like and riverbank-like initial conditions. A. philoxeroides showed an escape strategy of shoot elongation when its growth was suppressed by shallow submergence. No toxic symptoms but increased clonal spread was observed at high nitrogen concentrations, suggesting that A. philoxeroides not only tolerated but benefitted from nitrogen-polluted water. High nitrogen level mitigated the negative effects of submergence on its leaf survival, thereby enhancing its adaptation to water level fluctuation. Such strong adaptability and clonal spread helps A. philoxeroides to grow and invade successfully in shallow eutrophic water.
Relations Between Mn Concentration and Yield, Nutrient, Water Status, and Gas Exchange Parameters of Tomato

Published: May 2015

Abstract
Nutrition is one of the most important factors influencing quantitative and qualitative plant yield. This study examined the effect of manganese (Mn) in nutrient solution on photosynthetic activity parameters, and the relations between photosynthetic activity parameters, yield and plant nutrient status in tomato (Solanum lycoper-sicum L.). Mn supplementation significantly modified the nutrient content of leaves. Macronutrient content var-ied less than micronutrient content. The optimal Mn concentration differed between the studied cultivars. Both Mn deficit and Mn excess caused a decrease of tomato yield. Gas exchange parameters, relative water content (RWC) and specific leaf area (SLA) were measured in fully expanded tomato leaves. Certain levels of Mn were found to be needed for proper plant function and future yield, and toxic effects of excess Mn were noted. Changes in PN (net photosynthetic rate) were found to be the first signal of plant response to higher Mn supply, while yield was as for optimal Mn concentrations. Under Mn treatment, uptake of some nutrients increased. A higher level of absorbed Mg led to a higher photosynthesis rate and increased stomatal opening. PN and gs (stomatal con-ductance) also increased, while Ci (intercellular CO2 concentration) decreased, indicating proper CO2 consumption during the assimilation process.

Authors: Hell Marko , Dragičević Tea 
Published: May 2015

Abstract
Background: Organisations nowadays operate in a very dynamic environment, and therefore, their ability of continuously adjusting the strategic plan to the new conditions is a must for achieving their strategic objectives. BSC is a well-known methodology for measuring performances enabling organizations to learn how well they are doing. In this paper, “BSC for IS” will be proposed in order to measure the IS impact on the achievement of organizations’ business goals. Objectives: The objective of this paper is to present the original procedure which is used to enhance the BSC methodology in planning the optimal targets of IS performances value in order to maximize the organization's effectiveness. Methods/Approach: The method used in this paper is the quantitative methodology - linear programming. In the case study, linear programming is used for optimizing organization’s strategic performance. Results: Results are shown on the example of a case study national park. An optimal performance value for the strategic objective has been calculated, as well as an optimal performance value for each DO (derived objective). Results are calculated in Excel, using Solver Add-in. Conclusions: The presentation of methodology through the case study of a national park shows that this methodology, though it requires a high level of formalisation, provides a very transparent performance calculation.
Scoping Adaptation Needs for Smallholders in the Brazilian Amazon: A Municipal Level Case Study
Authors: Osuna Vanesa Rodríguez , Börner Jan , Cunha Marcelo 
Published: May 2015

AbstractOver the past decade, several climate extreme events have caused considerable economic damage and hardship in the Brazilian Amazon region, especially for small-scale producers. Based on household surveys and focus group interviews in the Municipality of Alenquer as well as secondary data analyses and a literature review at the regional level, this study seeks to assess rural small-scale producers’ vulnerability to climate and non-climate related shocks and identify entry points for government action to support adaptation at the local level. In our case study area, small-scale producers with similar wealth, self-sufficiency, and resource use specialisation levels exhibited stark variation in levels of sensitivity and adaptive capacity to climate and nonclimate related shocks. Our findings indicate that this variation is partly driven by cultural, historical, and environmental resource use specialisation strategies and partly by differences in local governance capacity and the level of social organisation. Emerging governmentled initiatives to promote climate change adaptation in the region would benefit from taking these factors into account when designing local implementation strategies and priorities.
Heat Alert and Response Systems in Urban and Rural Communities in Canada

Published: May 2015

AbstractHealth Canada reviewed national and international literature to develop a framework that identifies best practices for developing and implementing Heat Alert and Response Systems (HARS) to protect citizens from extreme heat events. A comparative case study was conducted based upon the framework and the experiences of two Canadian jurisdictions that piloted many of the best practices in the development of new HARS. Table-top exercises, heat-health vulnerability assessments, and community consultations were used to inform the development and implementation of HARS plans. Implementation of the framework by local authorities revealed different and unique challenges facing rural and urban communities in protecting people from extreme heat events. Opportunities within each pilot for taking effective public health adaptive actions that draw upon existing strengths and resources were also identified. Key aspects of HARS development including those related to education and engagement, development of an alert protocol, creation of a heat response plan, and identification of communication activities should be tailored to the needs of individual communities or regions and be informed by specific characteristics related to existing and future vulnerability.

Published: May 2015

SUMMARY
Oxidative stress is a basic mechanism involved in both ageand smoking-related diseases. To test whether smoking affects young, old, and calorie-restricted organisms to the same extent, we assessed oxidative stress parameters in the lung, heart, and liver of male Fischer 344 rats (4 months old and 19-22 months old) exposed to air or cigarette mainstream smoke. Smoke-related effects were seen for parameters of DNA damage, lipid peroxidation, protein oxidation, and glycoxidation. No smoke-related effects were observed for DNA damage in the lung and heart (Comet assay) and for malondialdehyde in the lung. The old rats showed higher smoke-related responses than the young rats for 8-hydroxy-desoxyguanosine (8-OHdG) in the heart and liver, DNA damage in the liver, and protein carbonyls in the lung; however, there was little evidence for an overadditive effect of smoking on aging. Caloric restriction, which is known to retard aging effects, also had little impact on smoke-related oxidative changes. [Beitr. Tabakforsch. Int. 26 (2014) 109-120]
