Photometric redshifts and clustering of emission line galaxies selected jointly by DES and eBOSS

We present the results of the first observations of the emission line galaxies (ELG) of the extended Baryon Oscillation Spectroscopic Survey. From the total 9000 targets, 4600 have been selected from the Dark Energy Survey (DES). In this subsample, the total success rate for redshifts between 0.6 and 1.2 is 71 and 68 per cent for a bright and a faint samples, respectively, including redshifts measured from a single strong emission line. The mean redshift is 0.80 for the bright and 0.87 for the faint sample, while the percentage of unknown redshifts is 15 and 13 per cent, respectively. In both cases, the star contamination is lower than 2 per cent. We evaluate how well the ELG redshifts are measured using the target selection photometry and validating with the spectroscopic redshifts measured by eBOSS. We explore different techniques to reduce the photometric redshift outliers fraction with a comparison between the template fitting, the neural networks and the random forest methods. Finally, we study the clustering properties of the DES SVA1 ELG samples. We select only the most secure spectroscopic redshift in the redshift range 0.6 < z < 1.2, leading to a mean redshift for the bright and faint sample of 0.85 and 0.90, respectively. We measure the projected angular correlation function and obtain a galaxy bias averaging on scales from 1 to 10 Mpc h(-1) of 1.58 +/- 0.10 for the bright sample and 1.65 +/- 0.12 for the faint sample. These values are representative of a galaxy population with M-B - log(h) < -20.5, in agreement with what we measure by fitting galaxy templates to the photometric data.
Fertility rebound and economic growth. New evidence for 18 countries over the period 1970-2011

Long-run impact of economic growth on fertility trends is ambiguous and sensitive for in-time variations. Noticeably, over last decades, economic growth has led to significant falls in total fertility rates in many countries. However, recently, in high-income economies a kind of ‘fertility rebound’ emerged (Goldstein, 2009; Luci and Thevenon, 2011; Day, 2012), which supports the hypothesis that reversal trends in total fertility rates are mainly attributed to economic growth. The paper unveils the relationship between total fertility rate changes and economic growth in 18 selected countries with fertility rebound observed, over the period 1970–2011, and detects the GDP-threshold at which the fertility rebound emerged. To report on the relationship we deploy longitudinal data analysis assuming non-linearity between examined variables. The data applied are exclusively derived from World Development Indicators 2013. Our main findings support the hypothesis on U-shaped relationship between the total fertility rate and economic growth in analyzed countries in 1970-2011. Along with the previous, we project the minimum level of GDP per capita (GDP-threshold) when the fertility rebound takes place.
Monte Carlo based reduction of image resolution in view of no-reference image quality assessment

In the paper a fast algorithm of image downsampling is presented which is based on the estimation of mean local luminance using the Monte Carlo method assuming the division of an image into smaller non-overlapping blocks. Due to modifications proposed in the paper, one can obtain similar results than for classical methods compared using recently proposed no-reference image quality metrics. Nevertheless, further optimization requires the development of no-reference image quality metrics with higher accordance to human perception of typical distortions. Streszczenie.

MEASURING DEGREE OF DEPARTURE FROM EXTENDED QUASI-SYMMETRY FOR SQUARE CONTINGENCY TABLES

For square contingency tables with ordered categories, the present paper proposes a measure to represent the degree of departure from the extended quasi-symmetry (EQS) model. It is expressed by using the Cressie-Read power-divergence or Patil-Taillie diversity index. The present paper also defines the maximum departure from EQS which indicates the maximum departure from the uniformity of ratios of symmetric odds-ratios. The measure lies between 0 and 1, and it is useful for not only seeing the degree of departure from EQS in a table but also comparing it in several tables.
Psychosocial school environment, satisfaction with school, and health complaints among Japanese high school students

This study aims to examine how students' perception of psychosocial school environment is associated with satisfaction with school and health complaints among Japanese high school students. A self-administered questionnaire was conducted with 2,852 students at 25 public high schools in Okinawa, Japan. The psychosocial school environment was measured by demands (unrealistic expectations), student autonomy and control (justice of the rules and participation in school activities), and support from teachers and students. Students who perceived high demands, low control, and low support reported the highest health complaints, whereas students who perceived low demands, high control, and high support showed the lowest complaints. Each demand-control combination with low support was more likely to have health complaints than those with high support. The high demands, high control, and high support group reported the highest satisfaction, whereas the low demands, low control, and low support group showed the lowest satisfaction. Each demand-control combination with low support had less satisfaction with school than those with high support. This study suggests that interventions which improve the psychosocial school environment are needed in order to promote school-related health.
Saving the Eurozone: Is a Real Marshall Plan the Answer?

z Renewed support for the view that austerity measures are not sufficient and that more robust policies to stimulate growth are required to help the eurozone, and especially southern Europe, survive its current crisis has triggered a debate about the merits of a 'Marshall Plan for Europe'. z z Faster productivity growth in the euro periphery could help improve competitiveness, fiscal arithmetic and living standards; the main role of a real Marshall Plan would be to promote supply-side reforms that raise productivity growth. This would repeat the main achievement of the original Marshall Plan of 1948. z z A real Marshall Plan would have to work as a 'structural adjustment programme', in much the same way as its famous predecessor, namely by achieving reforms through strong conditionality in return for serious money. To be credible the funds would have to be committed, but only released when reforms had been implemented satisfactorily - similar to the deal that worked in the context of EU enlargement in 2004. z z The experience of the Gold Standard's collapse in the 1930s suggests that seeking to keep the eurozone intact by imposing a 'golden straitjacket' on the policy choices of independent nation-states is not a viable option. This points to fiscal federalism with genuine democracy at the EU level as the long-run solution; a new Marshall Plan may not be a substitute for reforms of this kind, but it can certainly serve as a valuable complement.
From the Editors: What Grounded Theory is Not

Editor’s Note. Three years ago, I invited Robert (Bob) Gephart to write a “From the Editors” column designed to help authors improve their chances of success when submitting qualitative research to AMJ. Judging from the increasing number of qualitative studies that have been accepted and published in AMJ since that time, I would like to think that his article, “Qualitative Research and the Academy of Management Journal,” has had a positive impact. Continuing in this tradition, I asked Roy Suddaby—an excellent reviewer (and author) of qualitative research—to tackle another “big issue” that the editorial team has noticed with respect to qualitative submissions to AMJ: overly generic use of the term “grounded theory” and confusion regarding alternative epistemological approaches to qualitative research. Like Bob before him, Roy has, I believe, produced an analysis that will greatly benefit those who are relatively new to qualitative research or who have not yet had much success in getting their qualitative research published. Hopefully, Roy’s analysis will help even more authors to succeed, thus allowing AMJ and other journals to continue to increase the quality of insights provided by rich qualitative studies of individual, organizational, and institutional phenomena.

The Impact of Real Exchange Rate Uncertainty on Private Investment in Iran

This study sought to analyze the impacts of real exchange rate volatilities on investment in the private sector of the economy of Iran during the period 1961-2008, and also evaluate the impact of real exchange rate uncertainty on private investment behavior during the period under study. For this purpose, first, the uncertainty index of the real exchange rate is determined through auto-regressive patterns of conditional variance heterogeneity (EGARCH) and then it estimated the model. In this study, the entire economy of Iran has been studied during 1961-2008. It is a practical research, in terms of the research goal. In this study, GARCH models to obtain the uncertainty on the time series pattern have been used. Data analysis method is based on descriptive and inferential statistical research; according to inferential statistic, the research hypothesis has been tested. To verify or reject the hypothesis of this study, it was used Eviews software indicates that which variables a correlation exists between. The dependent variable in this model is ratio of the fixed investment to GDP and the independent variables include the import of capital goods, governmental investment, inflation index, GDP and real exchange rate uncertainty. The results showed that the index of real exchange rate uncertainty has a significant negative effect on private investment to GDP ratio, and imports of capital commodity and inflation have negative effects on private investment to
Experimental Study on Brush-Painted Passive RFID-Based Humidity Sensors Embedded into Plywood Structures

The integration of electronics and wood is an interesting research area due to the increasing interest to add functionality into various wooden products. The passive RFID-based humidity sensor tag prototype, presented in this paper, is fabricated directly on plywood substrate to be embedded into wooden structures, by using brush-painting and photonic sintering of cost-effective silver ink. To the best of our knowledge, this is the first demonstration of brush-painted antennas as sensor elements. The developed sensor tag is fully passive and small in size, meaning it can be permanently enclosed into wooden structures. In addition, the sensor tag has all the functionalities of an ordinary passive UHF RFID tag, and a peak read range of about 10 meters. The sensor performance was evaluated in normal room conditions, after two 100% relative humidity tests, and after drying in normal room conditions for 9 days. According to the results, the fabricated UHF RFID-based humidity sensor tags have a great potential to be utilized in humidity sensing applications, and also in normal automatic identification and supply chain control of various wooden products. In addition, the first results of more cost-effective brush-painted copper UHF RFID tags on plywood substrate are presented.
Combination of Multiple Acoustic Models with Multi-scale Features for Myanmar Speech Recognition

We proposed an approach to build a robust automatic speech recognizer using deep convolutional neural networks (CNNs). Deep CNNs have achieved a great success in acoustic modelling for automatic speech recognition due to its ability of reducing spectral variations and modelling spectral correlations in the input features. In most of the acoustic modelling using CNN, a fixed windowed feature patch corresponding to a target label (e.g., senone or phone) was used as input to the CNN. Considering different target labels may correspond to different time scales, multiple acoustic models were trained with different acoustic feature scales. Due to auxiliary information learned from different temporal scales could help in classification, multi-CNN acoustic models were combined based on a Recognizer Output Voting Error Reduction (ROVER) algorithm for final speech recognition experiments. The experiments were conducted on a Myanmar large vocabulary continuous speech recognition (LVCSR) task. Our results showed that integration of temporal multi-scale features in model training achieved a 4.32% relative word error rate (WER) reduction over the best individual system on one temporal scale feature.
The 'Publicness-puzzle' in public leadership. A theoretical exploration of leadership in public organizations

textabstractAbstract Following a contingency approach we argue that the content and style of administrative leadership depends on characteristics of the public context. The purpose of the paper is to develop hypotheses on the relationships between several dimensions of publicness and the content and style of leadership, by reviewing academic literature on public leadership. To build our argument we first conceptualize leadership and distinguish several theories, definitions, and styles of leadership based on four different basic conceptions of what leadership is: Leadership as traits; 2. Leadership as behavior; 3. Leadership as managing of meaning; 4. Leadership as interaction processes. Then, Bozeman’s model of publicness is described as well as the effects of publicness on organizational environments, organizational goals, organizational structures and managerial values. As a final step we develop hypotheses that relate leadership to publicness and identify possible contradictory demands administrative leadership has to deal with. We conclude by outlining a research agenda on administrative leadership.
Abyssal hill characterization at the ultraslow spreading Southwest Indian Ridge

The morphology of the flanks of the Southwest Indian Ridge holds a record of seafloor formation and abyssal hill generation at an ultraslow spreading rate. Statistical analysis of compiled bathymetry and gravity data from the flanks of the Southwest Indian Ridge from 54°E to 67°E provides estimates of abyssal hill morphologic character and inferred crustal thickness. The extent of the compiled data encompasses a spreading rate change from slow to ultraslow at ∼24 Ma, a significant inferred variation in sub‐axis mantle temperature, and a patchwork of volcanic and non‐volcanic seafloor, making the Southwest Indian Ridge an ideal and unique location to characterize abyssal hills generated by ultraslow spreading and to examine the effect of dramatic spreading rate change on seafloor morphology. Root mean square abyssal hill height in ultraslow spreading seafloor ranges from ∼280 m to ∼320 m and is on average ∼80 m greater than found for slow‐spreading seafloor. Ultraslow spreading abyssal hill width ranges from ∼4 km to ∼12 km, averaging ∼8 km. Abyssal hill height and width increases west‐to‐east in both slow and ultraslow spreading seafloor, corresponding to decreasing inferred mantle temperature. Abyssal hills persist in non‐volcanic seafloor and extend continuously from volcanic to non‐volcanic terrains. We attribute the increase of abyssal hill height and width to strengthening of the mantle portion of the lithosphere as the result of cooler sub‐axial mantle temperature and conclude that abyssal hill height is primarily controlled by the strength of the mantle component of the lithosphere rather than spreading rate.
Intertidal water column meiofauna in relation to wave intensity on an exposed beach *

High energy beaches are the most dynamic of soft-bottom habitats (McLachlan et al., 1996). These harsh habitats harbour a diverse and abundant fauna, including meiofauna and macrofauna (McLachlan, 1983). Some species of this fauna can actively enter the water column or be passively eroded from the sediment (Brown and McLachlan, 1990; Armonies, 1994). In beaches and other SCI.

Enzymatic Activity and Microstructural Changes of Hot Water Treated Banana during Ripening

Berangan banana were treated with hot water at 50 oC for 0 (control), 10, and 20 min and then kept at room temperature (25±2 oC), 75-80% RH to observe the ripening progress. Firmness and activity of cell wall degradation enzymes such as polygalacturonase (PG), pectin methylesterase (PME), and pectate lyase (PL) were determined for treated and untreated banana. The microstructure of banana peel cell wall was observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Treated fruit was firmer than the control fruit during ripening process. PG, PME, and PL activities were reduced in the treated bananas when compared with the control treatment. Hot water treatment disturbed cell wall degrading enzymes activity and delayed the disassembling of pectin fraction of Berangan banana. The micrographs of SEM and TEM exhibited lower changes in cell compartment and less loosening of cell wall fibril fractions in treated fruits. The electrolyte leakage in Berangan banana decreased with the increase of exposure time. The results of this study indicated that hot water treatment at 50 oC slowed down the ripening process and extended shelf life of banana.
The Dependency of Diffusion Coefficients and Geometric Factor on the Size of the Diffusing Molecule: Observations for Different Clay-Based Materials

In order to investigate in more detail the relation between the size of diffusing molecules and their diffusion coefficients (and geometric factors), diffusion experiments with gases of different size and tritiated water (HTO) have been performed on different clayey samples (Boom Clay, Eigenbilzen Sands, Opalinus Clay, Callovo-Oxfordian Clay, and bentonite with different dry densities). We observed that, for unreactive gases in clayey materials, the effective diffusion coefficient varies with the size of the diffusing molecule and this variation can be described by an exponential or a power law function. The variation of the geometric factor can also be described by an exponential function. The observed experimental relations can be used to estimate diffusion coefficients; by measuring experimentally in clay the effective diffusion coefficient of two unreactive dissolved gases with a different size, the diffusion coefficients of other dissolved gases (with a size in between the two measured gases) can be estimated by using the fitted exponential relationship.
Selection of Diluent for Short Term Preservation of Guinea Fowl Semen

This study was conducted to identify the suitable diluent for short-term preservation (0, 24 and 48 h) of Guinea fowl (pearl variety) semen. Semen samples were collected and diluted with normal saline, CARI, BPSE and Lake’s semen diluents and kept at 6°C for storage. No significant difference was found in sperm motility among the different diluents at 0 h (freshly ejaculated) storage period. A significant (p<0.05) reduction was found in sperm motility among all the diluents at 24 h storage period. Subsequently, there was no sperm motility was recorded in normal saline diluted semen samples at 48 h storage period. While a reduction (p<0.05) in sperm motility was recorded in rest of the three semen diluents. The mean values for fertility with freshly ejaculated semen during 2-12 days of fertile period were recorded as 66.27±4.08, 78.90±3.08, 64.90±4.87 and 67.99±6.36% whereas, after 24 h storage of semen, fertility reduced drastically such as: 0, 41.97±7.27, 36.09±8.72 and 30.90±7.12% in normal saline, CARI, BPSE and Lake’s semen diluent, respectively. No fertility was noticed at 48 h storage in any semen diluent. Irrespective of the storage period and diluents, CARI semen diluent expressed better fertility than others in Guinea fowl.
Alfalfa Establishment, Performance, and Persistence in Mississippi When Planted into a Bermudagrass Sward

Alfalfa is a high quality forage that is not often utilized in the southeastern United States because of its perceived lack of adaptability to the area. However, the risk of growing alfalfa could be partially mitigated by its inclusion into an existing bermudagrass system that makes up a large portion of pastures and hay fields in Mississippi. Alfalfa was planted into an existing bermudagrass hay field at a rate of 17, 22, 28 and 39 kg&middotha-1 in no-till and minimum till sod preparation and analyzed for three growing seasons. Tillage did not affect any of the variables observed but seeding rate and time affected DM (dry matter) yield, forage nutritive value and plot composition. The increasing alfalfa seeding rate increased alfalfa yield in the plot but this was isolated to only the first year. Dry matter yields decreased over the three years due to the decrease in alfalfa composition, but throughout the growing season DM yields increased after the first year suggesting bermudagrass recolonization within the plot. Forage nutritive value was positively affected with as little as 20% of the plot composed of alfalfa suggesting that even thinning stands by the third year might offer economic advantages.
