Environmental Proactivity and Environmental and Economic Performance: Evidence from the Winery Sector

Environmental sustainability in the winery sector is receiving increased attention from governments, environmental groups, and consumers. The aim of this study is to explore the relationship between the degree of proactivity of a firm’s environmental strategies and its business performance. The novelty of this research work lies in its definition of business performance, which includes business environmental performance in terms of reducing the firm’s environmental impacts and eco-efficiency in the use of resources such as water, energy, and raw materials, in addition to its economic performance. A model is proposed and tested using a sample of 312 Spanish wineries. Data were analysed using partial least squares path modelling (PLS-PM). The fitness and robustness of the structural model proved adequate. The results indicate positive correlation of environmental proactivity with economic and environmental performance. Although environmental proactivity improves business performance, it has a greater impact on reducing environmental impacts and improving eco-efficiency.
The Fingernail Protein Content May predict Bone Turnover in Postmenopausal Women

Background: Bone quality is a relatively new concept that seems to be able to fill the gaps we encounter in the prediction of osteoporosis by bone mineral densitometry. The aim of this study was to investigate relationship between finger nail protein and bone turnover in postmenopausal women. Methods: In a case-control study 123 postmenopausal women recruited from out patient clinic of Endocrinology and metabolism research center of Tehran University of Medical Sciences. In all participants DEXA scanning and spinal X-ray radiography were performed. Serum Osteocalcin and Cross laps concentrations were measured. Protein extraction from fingernail performed to evaluate protein content. Results: Fingernail protein content significantly correlated with serum Cross laps concentration (P= 0.03, r= -0.27), lumbar spine BMD (P= 0.01, r=0.4), and total hip BMD (P= 0.01, r= 0.33). In logistic regression analysis, fingernail protein content predicted vertebral fracture (P= 0.002). This relationship was independent of age, BMI, lumbar spine BMD, and total hip BMD. Conclusion: Common pathways may involve in structural protein synthesis. Thus evaluation of fingernail protein allows an estimation of bone quality, which would lead to a more complete evaluation of bone health.

A Microeconometric Model of a Short Run Cost Function with Unobserved Heterogeneity

Recent work has suggested plant level heterogeneity and discrete production processes can produce problems for estimation. A structural model of discrete production decisions by heterogeneous plants is constructed and, as a case study, estimated for the US Portland cement industry. In particular, an ordered probit model is extended to encapsulate the structural model and to handle incomplete ordering. This is the first application of the ordered probit model for the direct estimation of a short run cost function. The results broadly support the structure suggested by the industry technology and competitive conditions. Differences between industry averages of input requirements and many of the estimates of these coefficients are statistically insignificant.
What drives the distribution in nature of 3T vs. 2M1 polytype in muscovites and phengites? A general assessment based on new data from metamorphic and igneous granitoid rocks

Abstract Petrologic, chemical, and polytype data are presented for dioctahedral potassic micas from Kfeldspar- bearing metamorphic and igneous rocks of acidic composition unaffected by high-pressure (HP) conditions. The paper aims to demonstrate that: (1) under non-HP conditions, in both metamorphic and igneous plutonic environments, a given bulk-rock compositional constraint imposes a more or less marked phengitic composition to dioctahedral potassic mica; and (2) this muscovite crystallizes as 2M1, notwithstanding its phengitic composition. The samples (157 in number) are from widespread provenances. We conclude that the growth of 3T polytype of muscovite is not a function of mica composition. This is consistent with the recent crystallographic knowledge on polytypism, cation ordering, elastic properties, and structural deformational mechanisms of muscovite, which address the stabilization of 3T with pressure.
MIX DESIGN FOR OIL-PALM-BOILER CLINKER (OPBC) CONCRETE

An experimental investigation was conducted in mix design for lightweight concrete using Oil-Palm-Boiler Clinker (OPBC) as coarse aggregate. ACI mix design as used for normal weight concrete and mix design methods as used for lightweight concrete were employed to obtain the target compressive strength at 28-day and was found to be lower than the target strength for OPBC concrete. It was confirmed that the above established mix design methods couldn’t be used in this new OPBC concrete. Through trial mixes, the acceptable mix designs of this new concrete were obtained. The properties obtained from the acceptable mix designs were slumps of 40 to 100mm, demoulded densities of 1845 to 1980 kg/m3 and the 28-day compressive strengths of 27 to 35MPa. Keywords: Oil-Palm-Boiler Clinker (OPBC), Solid Waste, Mix Design, Lightweight Concrete, Compressive Strength
Instagram Use and It's Effect on Well-Being and Self-Esteem

Over the last ten years, social media has become an integral facet of modern society. In particular, image-based social networking sites such as Instagram have become increasingly popular among adolescents and young adults. However, despite this proliferation of use, the literature remains divided regarding the potential impacts of social media, particularly in regards to image-based platforms. The present study sought to analyze the relationship between social media usage patterns and its subsequent effects on user self-esteem and well-being. However, the study’s results show that, despite the existing literature, intensity of Instagram use serves as a mediating variable in this relationship. The study’s results show that it is intensity of use, not usage patterns, that determine user outcomes. Finally, the results show that users who engage with Instagram more intensely exhibit higher levels of self-esteem and well-being than users who do not use the application intensely.
Research into Pronunciation Learning Strategies of Pre-Service English Teachers.

Pronunciation, as being one of the core components of a language, plays key roles in language learning and language use. Many studies have already been conducted regarding pronunciation learning and its importance; yet, satisfactory attention has not been given to strategies and strategy use until recently. In line with this objective, this study aims to reveal pronunciation learning strategies of EFL learners in comparison with variables such as gender, age, grade level and years of learning English. A total of 27 pre-service EFL learners took part in the study. A strategic pronunciation learning scale was used to unearth most frequently used strategy types and strategy groups as well as effects of individual variables. Descriptive analysis was used to investigate the results. It was striking to see that there is a significant difference of pronunciation strategy use based on gender, and females use strategies more frequently. Another important factor was to see that even if there is statistically no difference, length of time for learning English can have a positive effect on pronunciation learning strategies.
Adaptation of glycoalkaloids detection method for evaluation of Latvian potato genetic resources.

The glycoalkaloid content in potato tubers can be i nfluenced by several factors: variety, weather, storage environment, maturity, da mage, temperature and exposure to light. Potato varieties vary with regard to their inherite d total glycoalkaloid (TGA) content. The problem in the practical use of most TGA detection methods is that they are money and time consuming. The aims of the investigation were adapt ation of a rapid and rather cheap method and evaluation of TGA content of varieties included in Latvia potato genetic resources. The used method was based on three earlier elaborated p rotocols of different authors. 31 varieties of Latvian potato genetic resources were examined for TGA content for two years, 10 of them for three years. TGA content depending on the variety r anged from 2 till 27 mg 100 g -1 fresh weight, the variance between genotypes was high. The significant genotype influence on TGA content was established. The influence of growing c onditions on TGA content was not significant.
Linking Perceived Quality on Attitudinal and Behavioral Loyalty: An Evidence from Indonesian App-Based Transportation

This study investigated app-based transportation customers’ perception of quality, and its effect on satisfaction, attitudinal, and behavioral intention in the means-end theory perspective. A causal design survey was applied out of 90 customers from South Tangerang City, Province of Banten, Indonesia and the data were analyzed by using Partial Least Square (PLS). The research finding indicated that the relationships between perceived quality, satisfaction, attitudinal and behavioral intention were confirmed. There was a positive significant relationship of environmental quality and customer satisfaction (β = 1.131; sig. = 0.000; CR > 2.0). Ambient condition contributed a higher influence on environmental quality than another indicator. Ambient condition was defined as a nonvisual factor affecting consumer perceptions of service quality. Moreover, satisfaction also had a positive relationship of attitudinal and behavioral loyalty (β = 0.807; β = 0.743; sig = 0.000 and CR > 2.0). The indirect influence of service environmental quality on attitudinal and behavioral loyalty was also confirmed through an intermediate variable of satisfaction (β = 0.912; β = 0.840; sig = 0.000 and CR > 2.0). The finding is worthwhile not only for companies, but also for the welfare of drivers who mostly come from low income groups. For the company, positive attitudinal and behavioral loyalty will increase market profitability and market share in the long run. As for drivers, this condition will provide job security and welfare guarantee.
Modified Artificial Diet for Mass Rearing of Chickpea Pod Borer, Helicoverpa (Heliothis) Armigera (Hubn)

This paper reports on a comparison of a modified diet with other diets and procedures used in mass rearing of Helicoverpa armigera. The results on the biology of H. armigera reared on the modified diet for up to six consecutive generations indicate that the pupal recovery percentage ranged form 71.2±9.59 to 83.7±5.98; the adult energence percentage varied from 59.6±3.15 to 78.4±3.29. The maximum egg yield/female was recorded to be 273.3±13.6 in the first generation. The average cost to produce one pupa of this insect was calculated to be Rs. 0.60, which in equivalent ot half the cost of production per pupa using other diet formulas.
Increased vulnerability of Zostera noltii to stress caused by low light and elevated ammonium levels under phosphate deficiency

The effects of light and ammonium levels on net production, fluorescence parameters and non-structural carbohydrates of the seagrass Zostera noltii under different phosphate conditions were studied. A fully factorial design was used with light (low/high levels), ammonium supply and phosphate preculture conditions of the plants as the experimental variables. Both ammonium supply and low light caused negative and synergistic effects on net production, while ammonium toxicity was more severe at high light levels; in this case, it was independent of the non-structural carbohydrate (sucrose and starch) content. Preculturing of plant with added phosphate alleviated the ammonium toxicity, and also attenuated the negative production balance of plants grown at low light levels. The results indicated that phosphate preculture ameliorated the plant’s short-term response against the assayed stressors (low light, high ammonium) significantly. An overall consumption of non-structural carbohydrates in response to environmental stressors was recorded throughout the experiment, indicating the importance of carbon and phosphorus reserves to cope with adverse conditions. In addition, phosphate deficiency increased the vulnerability of plants, which could have negative ecological consequences for seagrass species thriving under phosphate deficiency conditions, or in developing seagrass transplantation programs.
Asymmetric relationship between oil price and exchange rate: The case of Romania

The fragile structure of the global economy in the last decades makes it necessary for policy makers to have consistent predictions on the future values of the commodities and assets and also exchange rates. The fact that it is still the biggest source of energy, oil, has a crucial importance for the real economy and even financial markets. In this study, the relation of the real oil price and the real exchange rate in Romania will be investigated for the period of 2004:4 to 2014:10 using monthly data. Results in the tests suggest that Romania should consider the real oil price and real exchange rate causality due to the fact that there is a significant causality between the variables.
An analytical study of air circulation in caves

The motion of the air inside caves plays an important role in the field of cave meteorology. The causes of the motion can be grouped into two different classes, i.e. static or dynamic ones. Common static causes are those directly connected with a thermodynamic transformation concerning the cave air, such as a variation of temperature, of composition or of, pressure. Under the dynamic causes one can cite moving fluids such as water or air. In the present study a hybrid unit system has been preferred because pressures are generally measured in "Torr" (under the conditions of the present work it can be assumed 1 Torr = 1 mm Hg) while other quantities (temperature, length, density, etc.) are reported in technical ! ilKS units. Therefore a dimensionless factor, multiplying pressures in Torr is introduced every time it is necessary. Thus the equations here obtained will be easier employed, without any change, to study the results of many measurements in caves. In this paper particular emphasis has been given to the quantitative solutions of the air circulation problems. Several authors have described the details of the qualitative characteristics and it is not worth while to repeat them here (Crestani and Anelli, 1939; Eraso, 1962/63; Montoriol Pous, 1951, 1959; Myers, 1953; Trombe, 1952).
Induction of Somatic Embryogenesis through Overexpression of ATRKD4 Genes in Phalaenopsis “Sogo Vivien”

Phalaenopsis “Sogo Vivien “is a mini orchid hybrid with beautiful flowers and numerous inflorescences. Mass propagation of this orchid is needed to meet the market demand. Objective of this research was to induce somatic embryogenesis of P. ”Sogo Vivien” through insertion of AtRKD4 gene into orchid. T-DNA containing 35S::GAL4::AtRKD4::GR was inserted into 16-22 days after sowing orchid protocorms mediated by Agrobacterium tumefaciens EHA 105. Activation of the AtRKD4 gene was induced by glucocorticoid induction system, using 15μM Dexamethasone (Dex). The results showed that 34 out of 2,648 orchid embryos developed into protocorms on hygromycin selection medium, whereas only 4 out of 2,897 non-transformant protocorms developed from embryos. A 500 bp of HPT genes was amplified from transformant candidates using specific primers for HPT (HygF1 and HygR1) and 380 bp was amplified using specific primers for AtRKD4 (AtRKD4 F1 and AtRKD4 R1), indicated that transgenes have been integrated into orchid genomes. Finally, 17 plantlets were positively carrying AtRKD4 and HPT genes, the efficiency of transformation was 0.63 %. Somatic embryos were also emerged from leaf explants of transformant on hormone-free NP medium and became normal plantlets. It is probably due to the high activity of AtRKD4 genes in orchids
A Note on the Coalgebraic Interpretation of Game Logic

We propose a coalgebraic interpretation of game logic, making the results of coalgebraic logic available for this context. We study some properties of a coalgebraic interpretation, showing among others that Aczel’s Theorem on the characterization of bisimilar models through spans of morphisms is valid here. We investigate also congruences as those equivalences on the state space which preserve the structure of the model.
THE SIGNIFICANCE OF LIE THEORY IN THE GEOMETRY OF ROLLING MOTIONS

The main goal of this paper is to present a unifying theory to describe the pure rolling motions of Riemannian symmetric spaces. We make a clear con- nection between the structure of the kinematic equations of rolling and the natural decomposition of the Lie algebra associated to the symmetric space. This empha- sizes the relevance of Lie theory in the geometry of rolling manifolds. It becomes clear why many particular examples scattered through the existing literature always show a common pattern.
Hydrogen isotope compositions in carbonado diamond: constraints on terrestrial formation

Abstract In this study we report the first hydrogen isotope composition analyses on carbonado diamond along with cathodoluminescence and scanning electron microscopic imaging, electron microprobe analyses, and stable (H and C) and radiogenic (Sr) isotope measurements. The hydrogen of bulk carbonado (consisting diamond and pore-filling minerals) yielded ∼ −4‰, consistent with usual crustal or mantle-derived fluids. The diamond-related hydrogen component is about 70 ± 30 ppm and shows a D-depletion down to −200‰. Determined H isotope values — together with C isotope compositions — overlap the ranges for mantle-derived hydrocarbons. Textural characteristics and Sr isotope ratios of pore-filling florencite indicate that the carbonado was formed in a fluid-rich environment, underwent a significant high-temperature influence and finally suffered thorough alteration. Based on these observations, a terrestrial formation during interaction of mantle rocks/melts or subducted crustal materials and reduced C-H fluids.
Opportunity Structures in Established Firms

This study revisits the well-established notion that large and mature organizations stifle an employee’s ability and motivation to become an entrepreneur. Using unique data on U.S. mutual funds founded between 1979 and 2005, I examine whether large and mature firms, which are typically associated with lower individual rates of entrepreneurship, are also associated with lower individual rates of intrapreneurship. The findings show that, though employees in large and mature organizations are less likely to transition to entrepreneurship, they nonetheless exhibit a higher propensity to pursue venturing opportunities inside the established firm than employees in smaller and younger firms. The results suggest that the observed negative effect of large, mature organizations on entrepreneurship arises partly due to high rates of intrapreneurship and that the stultification processes in such organizations are far less important than has been generally assumed.
Factors affecting farm size on the European level and the national level of the Czech Republic

Extreme diff erences in agricultural holding size, existing not only among the countries within the EU as a whole but also within the farm structures of the individual countries, create a considerable uncertainty for establishing the optimal political and economic instruments to support sustainable rural development. Th e study explores the determinants infl uencing the spatial volatility of agricultural holding size at both the EU scale and the national scale of the Czech Republic, the latter of which has the largest mean agricultural holding size in the EU. While some factors are identical for both the EU and the Czech Republic, other eff ects can only be evaluated at the European or international scale, and still others can be evaluated only at the national scale. Th e only factor found in this study to be signifi cantly associated with the agricultural holding size on the European scale was the wheat production. On the Czech national scale, land consolidation, unemployment rate, and soil fertility were signifi cantly associated with the agricultural holding size. Th e study found that in the Czech Republic, the number of farms was increasing, while at the same time the agricultural holding sizes were decreasing. Th is is an opposite trend in comparison to the EU as a whole, where the number of farms is diminishing and the sizes increasing.
Intentional Memory Instructions do not Improve Visual Memory

The current experiment examines whether intentional encoding instructions improve long-term recognition memory for visual appearance. Past experiments suffer from various methodological flaws, such as inadequate statistical power or confounding of variables such as attention and task relevance withintentional memory instructions.In the current experiment, the effect of memory instructions was examined using a factorial design, so that attention to/task relevance of objects could be manipulated independently of memory instructions. The sample size was large enough to achieve power equal to . 80 for medium effect sizes (f = .25). There was no effect of intentional memory instructions. These results suggest that observers cannot easily enhance encoding and storage of visual information in long-term memory.
Is Earnings Management a Technique to Reduce Cost of Capital？ Exploratory Study on Indian Companies

Earnings management has attracted lots of academicians towards the research due to the emerging frauds and downfall of great corporate giants of the world. Mainly earnings measurement is based on the accounting estimates which managers can easily manipulate for their self-interest. The study investigates the relationship between cost of capital and the earnings measurement for the Indian firms. Measurement of earnings is mostly computed by taking either discretionary accruals (DAC) or non-discretionary accruals (NDAC). Present study has used Dechow, Sloan, and Sweeney (1995) model for earnings measurement and for analyzing the results. Panel data regression has also been used. Findings of the study conclude that DAC has a significant influence on cost of capital, but NDAC has no influence.
Relationship between the Religious Attitude, Self-Efficacy, and Life Satisfaction in High school Teachers of Mahshahr City

This study aims to investigate the relationship between the religious attitude, self-efficacy, and life satisfaction in high school teachers of Mahshahr City. To this end, 253 people of all high school teachers in Mahshahr City, in Iran were selected as the sample using the multistage cluster sampling method. For data collection, Glock and Stark’s (1965) religious attitude questionnaires, Schwartz and Jerusalem’s general self-efficacy questionnaire and Diener et al.’s (1985) life satisfaction questionnaire were used. For data analysis, Pearson’s correlation coefficient was used. Results showed that there is a positive and meaningful relationship between the religious attitude and life satisfaction. In addition, there is a meaningful relationship between the religious attitude and self-efficacy. Results also showed that religious attitude and self-efficacy can predict the life satisfaction.
