Text Difficulty Effect on Metacognitive Reading Strategy Use among EFL Learners

Reading is one of the most integral academic skills in learning a foreign language. According to Anderson (2003), it is the interaction of four factors: the reader, the text, fluent reading and strategic reading. A large number of studies have indeed recognized the importance of the metacognitive reading strategies (MRSs) and text difficulty in reading comprehension. However, the effect of text difficulty on the learners' MRSs use has not been paid due attention in the literature. Accordingly, this study, employing a within-subject design, investigated the effects of text difficulty on MRSs use. Sixty Iranian intermediate EFL learners from two private institutes were asked to answer the Metacognitive Awareness of Reading Strategies Inventory questionnaire (Mokhtari & Reichard, 2002) at three different times, focusing on pre-intermediate (KET), intermediate (PET), and upper intermediate (FCE) texts. To get a better picture of the EFL learners' MRSs, an oral interview was also carried out on 10 participants. The results of the statistical analyses showed that text difficulty had significant effect on metacognitive reading strategy use with problem-solving strategies being affected most. The interview data revealed that the participants in this study benefited from various MRSs such as planning, summarizing and translating especially when the text was difficult. The implications of the study concern foreign language teaching, teacher training and curriculum design with regard to the selection of appropriate reading materials and methodology for EFL learners. Moreover, EFL instructors need to consider the difficulty level of reading materials so as to trigger the learners’ metacognitive reading strategy use.

A Euenantiornithine Bird from the Late Cretaceous Haeg Basin of Romania

We present the first record of a euenantiornithine bird from Romania. A small collection of fossil remains from the Maastrichtian add to the known distribution of large euenantiornithines and descriptions of birds from the Haţeg Basin augment the known vertebrate fauna from this famous region of Transylvania. The new specimens referred here to an indeterminate taxon of euenantiornithine further demonstrate that the larger members of this diverse Cretaceous lineage were globally distributed, as many birds are today.
A Grid of Synthetic Spectra for Hot DA White Dwarfs and Its Application in Stellar Population Synthesis

In this work we present a grid of LTE and non-LTE synthetic spectra of hot DA white dwarfs (WDs). In addition to its usefulness for the determination of fundamental stellar parameters of isolated WDs and in binaries, this grid will be of interest for the construction of theoretical libraries for stellar studies from integrated light. The spectral grid covers both a wide temperature and gravity range, with 17,000 K ≤ Teff ≤ 100,000 K and 7.0 ≤ ≤ 9.5. The stellar models are built for pure hydrogen and the spectra cover a wavelength range from 900 Å to 2.5 μm. Additionally, we derive synthetic HST/ACS, HST/WFC3, Bessel UBVRI, and SDSS magnitudes. The grid was also used to model integrated spectral energy distributions of simple stellar populations and our modeling suggests that DAs might be detectable in ultraviolet bands for populations older than ∼8 Gyr.
Transformational Leadership and Employee Voice Behavior: A Pygmalion Mechanism

We theorized and examined a Pygmalion perspective beyond those proposed in past studies in the relationship between transformational leadership and employee voice behavior. Specifically, we proposed that transformational leadership influences employee voice through leaders’ voice expectation and employees’ voice role perception (i.e., Pygmalion mechanism). We also theorized that personal identification with transformational leaders influences the extent to which employees internalize leaders’ external voice expectation as their own voice role perception. In a time-lagged field study, we found that leaders’ voice expectation and employees’ voice role perception (i.e., the Pygmalion process) mediate the relationship between transformational leadership and voice behavior. In addition, we found transformational leadership strengthens employees’ personal identification with the leader, which in turn, as a moderator, amplifies the proposed Pygmalion process. Theoretical and practical implications are discussed.
Mediator analysis in the management of innovation in Indian knowledge workers: the role of perceived supervisor support, psychological contract, reward and recognition and turnover intention

While examining the field of innovation, a research gap was found concerning the need to examine the contextual factors affecting management of innovation and turnover intention (TI) in knowledge workers. Investigating a sample of Indian knowledge workers (n = 312) and applying multilevel modelling (MLM) using structural equation modelling, the current study found that the psychological contract and rewards and recognition were strong mediators between perceived supervisor support, innovation and TI. A better fit model emerged when examining four competing models using MLM. This research examines the theoretical and practical implications of the results.
Endogenous differential mortality, non monitored effort and optimal non linear taxation

This paper studies the normative problem of redistribution among individuals who can influence their longevity through a non-monetary effort but have different taste for effort. As benchmarks, we first present the laissez-faire and the first best. In the first best, the level of effort is always lower than in the laissez-faire as the social planner takes into account the consequences of higher survival on the budget constraint. However, since we suppose that effort is private and non-monetary (like exercising), it is reasonable to think that the social planner has no control over it. Thus, we modify our framework and assume for the rest of the paper that effort is determined by the individual while the social planner only allocates consumptions. Under full information with non monitored effort, early consumption is preferred to future consumption and the high-survival individual obtains higher future consumption. Under asymmetric information, the distortion is identical for the low-survival individual while the direction of the distortion for the high-survival individual is ambiguous. We finally show how to decentralize these allocations through a perfect annuity market and (positive or negative) taxes on annuities.
Molecular detection of Mycobacterium tuberculosis and its relationship to histopathological diagnosis in paraffin-embedded lymph node tissues

Background: Tuberculous lymphadenitis (TBL) is one of the most common forms of extra pulmonary tuberculosis (EPTB) worldwide, with difficulty in its diagnosis. And since in the Sudan, the routinely used method for diagnosis is conventional histopathology, the aim of this study was to confirm the histopathological diagnosis by polymerase chain reaction (PCR). Methods: In this study 718 lymph node (LN) biopsies were retrieved, of which 161 were diagnosed as TBL (histopathological evidences). PCR technique was performed for all 161 positive samples to detect the IS6110 sequence of M. tuberculosis as well as to obtain the sensitivity and specificity of morphological diagnosis. Results: Out of 161 specimens 135 (84%) were found to be positive with PCR, the remaining 26 (16%) were negative. Conclusions: Although PCR indicated high sensitivity it can’t be a substitute for conventional histopathology in the diagnosis of tuberculous lymphadenitis in tissue.
Rootstock growth and development for increased graft success of mango ( Mangifera indica ) in the nursery

The graft success of seedlings depends on rootstock size and the skills of grafters. A study was carried out to evaluate the effects of rootstock diameter (at root collar), skills and experience of grafters on mango seedling thinning and grafting. Skilled and unskilled grafters were involved in grafting mango plants for at least three consecutive months. Different rootstock sizes based on root collar diameter of mango seedlings were assessed. The results showed significant differences in graft-take among three groups of nurserymen. The skills and experience of grafters had a significant effect on graft success. The late emerging seedlings showed higher increase in height and diameter after thinning. A higher survival (> 75%) and reduced time to graft-take (19 days) were achieved with thicker rootstocks (0.7 cm) than thinner rootstocks (0.3 cm). The early emerging plants produced more leaves than late emerging plants after grafted. It was concluded that a higher graft-take can best be achieved with skilled grafters and thicker rootstocks.
Effect of Board Social Capital on Innovativeness in the Banking Industry in Kenya

Extant literature on impact of board capital on firm innovativeness, was prior to this research inconclusive, with some studies showing positive, negative or no effect. Anchored on agency, resource dependence and social capital theories, the researcher sought to determine impact of social capital on innovativeness in banks. Kenya has experienced innovations in the banking sector driven by mobile technologies. The researcher hypothesized that social capital positively impacts firm innovativeness. Independent variables were director interlocks, status and prestige of the directors and presence of personal or other affiliations between directors and the bank or chief executive. Two control variables were added, to mitigate their confounding effect on bank innovativeness. A causal research design was selected and purposive sampling undertaken to choose respondents to a questionnaire. Unit of analysis was boards of banks. 32 questionnaires were returned, a response rate of 74%. Data was analyzed using SPSS, after testing for assumptions made. The study found there was statistically significant relationship between director interlocks and status and prestige of the directors and innovativeness of banks. This study resolved disagreement in extant literature, concluding that board interlocks and board status and prestige were found to drive innovativeness. There was no statistically significant relationship between presence of personal or other affiliations between the directors and the bank or chief executive and bank innovativeness. This study benefits management, in providing a selection criteria for directors of entities focusing on innovativeness. Major limitation of the study is the narrow focus on banking sector impacting generalization of the study
Chronicling the Transient Nature of Fitness Employees: An Organizational Culture Perspective

This study adopted an organizational culture perspective to examine the values and beliefs within fitness club operations and determine their influence on employees’ job satisfaction and intention to leave an organization. Consideration was also given to subcultures based on geographical location, organizational type, and job function to examine the ways in which organizations and employees may differ. Data were collected at three urban cities in Canada during a major fitness conference and tradeshow. The results from 438 employees confirmed the multidimensionality of the seven-factor instrument, in addition to illustrating the influence on job satisfaction and intention to leave. Further, the results revealed several dimensions were perceieved differently with respect to subculture. Findings connote the transient nature of jobs in the fitness industry which remains an immediate concern for managers in this field.
Abrupt equatorial wave‐induced cooling of the Atlantic cold tongue in 2009

Between May and August 2009 sea surface temperatures (SSTs) in the eastern equatorial Atlantic dropped 5°C, from 1°C above normal to 1°C below normal. The magnitude of this cooling is unprecedented since satellite SST measurements began in 1982. In this study, observations and a linear equatorial wave model are used to examine the causes of the sharp decrease in SST. It is found that the anomalous cooling along the equator can be traced to an anomalous meridional gradient of SST and associated northwesterly anomalous winds that developed in the equatorial Atlantic the preceding spring. The anomalous winds forced upwelling equatorial Rossby waves that propagated westward during boreal spring and reflected at the western boundary into upwelling Kelvin waves during late spring and summer. The upwelling Kelvin waves propagated eastward along the equator, anomalously decreasing sea level and SST during May–August.
Seed treatment with GA 3 or stratification enhances emergence of some strawberry tree genotypes - Short communication

Demirsoy L. , Demirsoy H. , Celikel G. , Macit I. , Ersoy B. , 2010: Seed treatment with GA 3 or stratification en hances emergence of some strawberry tree genotypes – Short communication . Hort. Sci. (Prague), 37: 34–37. The strawberry tree is a valuable ornamental plant because of its attractive red fruits in the fall and winter, and pink ish-white flowers in fall. Additionally, its fruits are processed into various products such as jam, marmalade, wine and alcohol. Since, propagation of the strawberry tree is difficult. This study aimed to examine the influence of stratification and GA 3 on breaking seed dormancy and enhancing emergence rate of Arbutus unedo. The influence of seed treatment with GA 3 or stratification at 4°C was examined on emergence of five genotypes of strawberry tree ( Arbutus unedo L.) near the Black Sea in Turkey. Results indicate that emergence rate increased with increasing GA 3 concentration from 300 to 1,200 ppm and stratification duration from 5 to 15 weeks. In all examined genotypes, the highest emergence rate was obtained using 1,200 ppm GA 3 or 15 weeks of stratification. Regardless of the positive effects of the above treat ments, seed emergence rates in all genotypes examined in this study were low. Application of GA 3 or stratification of seeds increased emergence percentage in all Arbutus unedo genotypes examined in the current study.
Monitoring and managing Ceratitis spp. complex of sweet orange varieties using locally made protein bait of brewery waste.

Introduction . Fruit flies contribute significantly to yield losses experienced by citrus farmers in Nigeria. The majority of farmers have meager resources and limited knowledge of appropriate citrus pest management strategies. The best alternative for them is the application of control methods that are environmentally friendly and affordable. Our work was therefore designed to develop baits from a cheap source for monitoring fruit fly populations and controlling them while minimizing environmental hazards. Materials and methods . Protein bait prepared locally from brewery yeast waste by the process of heat autolysis was compared with the imported protein hydrolysate bait in McPhail traps. These traps were hung on the trees of four sweet orange varieties during the major citrus fruiting seasons of 2003 and 2004. Results . Species of Ceratitis dominated in the fruit fly samples collected. Both the imported and locally made baits caught significantly higher numbers of fruit flies than the non-baited control. There was no significant difference between the populations of fruit flies caught by the two baits during the studies. The decreasing order of varieties according to trapped fruit fly numbers for both the imported and locally made baits were: Washington navel > Parson Brown > Valencia late > Agege-1. The fruit fly numbers observed on Washington navel were significantly higher than those of Agege-1 and Valencia late. Discussion . Our results show the effectiveness of the locally made protein bait in fruit fly monitoring and management. Varietal differences also played a part in determining the extent of fruit fly attacks on sweet oranges.
Refinement and evaluation of artificial diet for rearing of legume pod borer, Maruca vitrata Geyer (Lepidoptera: Crambidae)

The investigation on refinement and evaluation of artificial diet for M. vitrata, were carried out during 2014 and 2015 under walk in plant growth chamber established at ARS, Gulbarga, Karnataka, India. Comparison of developmental parameters of three successive generations of M. vitrata reared on different diets revealed that, maximum survival of egg, larva and pupa was 78.4 ± 3.1, 67.6±5.5 and 73.0±5.0 respectively in modified D-OOD diet and was superior over rest of the diets (D-OOD, D-New and D-OO) while it was on par with natural host plant. Maximum fecundity of 62.34±4.1 eggs/female was observed in refined D-OOD diet was on par with pigeonpea host plant and superior over other diets. Biology studies of Maruca on refined artificial diet in comparison with natural host plant pigonpea were revealed that, incubation period (2.6 ± 0.46 and 2.85 ± 0.40 days), total larval duration (14.28± 1.02 and 14.78±1.52 days), pupal period (9.41±0.70 days and 10.33±1.08 days) did not vary significantly between modified diet and natural host. Fecundity in refined artificial diet was 66.00 ± 4.00 and it was 65.99± 7.02 eggs on natural host plant. Per cent egg hatching was almost same in both the cases.
Butterfly community assemblages in relation to human disturbance in a tropical upland forest in Ghana, and implications for conservation

The present study determined butterfly diversity, species composition and abundance in different forests of varying human disturbance intensities in the Atewa Range Forest Reserve, Ghana (i.e. non-disturbed, moderately disturbed and heavily disturbed forests). Vegetation characteristics and butterflies were sampled within ten 50 m × 50 m plots in each forest type. The study revealed that butterfly Shannon diversity index was similar in the non-disturbed and moderately disturbed forests although it was significantly lower in the heavily disturbed forest. Butterfly abundance differed significantly among all the forest types. Significant relationships were detected between some vegetation characteristics, and butterfly diversity and abundance ( P <0.001). Using Non-metric Multidimensional Scaling (NMDS) and cluster analysis, three main butterfly assemblages were identified on the basis of species composition, with each one in a particular forest type. Furthermore, butterfly species composition differed significantly among the forest types (ANOSIM; P <0.0001). The intermediate form of human disturbance in the moderately disturbed forest maintained butterfly diversity, suggesting that management efforts aimed at butterfly conservation should be geared towards protecting forests from excessive human disturbance; selective logging is recommended.
Influence of Polyglycidyl-type Bonding Agents on the Viscoelastic Properties of a Carboxyl-terminated Poly(butadiene-co-acrylonitrilе)-based Composite Rocket Propellant

In the present study, functionally substituted bonding agents (triglycidyl isocyanurate and diglycidyl dimethylhydantoin) were incorporated into a composite propellant formulation based on carboxyl-terminated poly(butadiene-co-acrylonitrilе) and ammonium perchlorate. Bonding agents are an important component of a composite propellant, making up to 0.5 wt. % of the formulation. They affect processing, mechanical properties, ballistics, ageing and the characteristics of insensitive munition (IM) propellants. All of the testing has been done using an unmetallized propellant formulation (80 wt.% bimodal ammonium perchlorate and 20 wt.% binder). The focus has been on the mechanical properties of the propellant, as influenced by the presence of these bonding agents. Mechanical uniaxial tensile tests were accompanied by a dynamic mechanical analysis (DMA) over a wide range of temperatures. The storage modulus, loss modulus, loss factor and glass transition temperature for each propellant sample have been evaluated. The network characteristics, such as sol-gel content and crosslink density have been calculated and successfully correlated with the mechanical properties. The dynamic mechanical studies showed that the content of the bonding agent did not influence the glass transition temperature; however, the loss factor was shown to be a function of the crosslink density.

Chemical abundances for the outer halo cluster Pal 4 from co-added high-resolution spectroscopy

Context. Chemical element abundances for distant Galactic globular clusters (GCs) hold important clues to the origin of the Milky Way halo and its substructures. Aims. We study the chemical composition of red giant stars in Pal 4 – one of the most remote GCs in the Milky Way – and compare our abundance measurements to those for both low surface brightness dwarf galaxies, and GCs in the inner and the outer halo. Methods. By co-adding high-resolution, low-S/N Keck/HIRES spectra of 19 stars along the red giant branch, we estimate chemical abundance ratios of 20 α-, iron peak-, and neutron-capture elements. Our method gives total uncertainties on most element-to-iron ratios of typically 0.2 dex. Results. We measure [Fe/H] = -1.41 ± 0.04 (statistical) ± 0.17 (systematic) and an α-enhancement of [α/Fe] = +0.38 ± 0.11 dex, which is consistent with the canonical value of ~+0.4 dex found for Galactic halo field stars and most halo GCs at this metallicity. Although Pal 4 has higher enhancements in the heavier elements with respect to the halo, the majority of the element ratios are, within the measurement errors, consistent with those for local halo field stars. We find, however, evidence for a lower [Mg/Ca] ratio than in other halo clusters. Conclusions. Based on the available evidence, we conclude that the material from which Pal 4 and the Galactic halo formed experienced similar enrichment processes, despite the apparently younger age of this cluster. Within the limitations of our methodology we find no significant indication of an iron spread, as is typical of genuine GCs of the Milky Way. However, abundance ratios for individual stars in Pal 4 and other distant satellites are urgently needed to understand the relationship, if any, between remote GCs and other halo substructures (i.e., luminous and ultra-faint dwarf spheroidal galaxies).
