The influence of leader empowering behaviors and employee psychological empowerment on customer satisfaction

Purpose – This study aims to examine the role that psychological empowerment (PE) and employee satisfaction (ES) play in the relationship between leader empowering behaviors (LEB) and customer satisfaction (CS) and employees' organizational commitment (OC). Design/methodology/approach – Data were collected from 365 frontline employees and 2,915 customers at 40 units of a chain restaurant in the USA. Findings – Structural equation modeling (SEM) results indicated that LEB influences PE, and PE in turn influences employee satisfaction, which consequently results in higher employees' OC levels and higher customer satisfaction. Originality/value – Although recent hospitality research recognizes the importance of employee empowerment and leadership, few studies have focused on leader empowering behaviors and its influence on organizational outcomes. Moreover, potential mediating processes have not received research attention. Addressing this, the current study tests a conceptual model that shows how leader emp.
Tribological Aspects of Graphene-Aluminum Nanocomposites

Graphene is a new class of material in carbon group with strong sp 2 —hybridized 2D-sheet like nanomaterial. In order to make an effective utilization of their astounding properties, they are currently used in the form of reinforcements in various proportions in metals and its alloys to fabricate the nanocomposites. Graphene is incorporated in oil and grease at nano range that results in higher load-carrying capacity compared with that of raw grease and oils without additives, which shows that graphene possesses self-lubricating capacity. Graphene is a planar sheet-like structure (2D), with more contact surface area in the developed composites that can make them suitable for industrial applications with well-established tribological performance. The novelty of this work focuses on the role of graphene addition in enhancing the wear performance aluminum composites to replace the conventional materials by graphene composite combinations. The current chapter explains the processing and tribological performance of graphene-aluminum composites and its effect with various hybrid combinations of MWCNT/SiC/Al 2 O 3 . Dispersion of graphene is carried out through ultrasonic liquid processor followed by ball-milling alumi- num powder. Thus prepared precursors are vacuum-pressed and microwave-sintered. Graphene in the nanocomposites has resulted in significantly improving the tribological properties, where it gives the wear resistance by creating a solid, lubricant layer between the sliding surfaces.
Analysis of the time series of waste water quality at the inflow of the wastewater treatment plant and transfer functions

Abstract Time series of the daily total precipitation, daily wastewater discharges and daily concentrations and pollution loads of BOD5, COD, SS, N-NH4, Ntot and Ptot were analyzed at the inflow to the wastewater treatment plant (WWTP) for a larger city in 2004-2009 (WWTP is loaded by pollution from 435,000 equivalent inhabitants). The time series of the outflow from a WWTP was also available for 2007. The time series of daily total precipitation, daily wastewater discharges, concentrations and pollution loads at the inflow and outflow from the WWTP were standardized year by year to exclude a long-term trend, and periodic components with a period of 7 days and 365 days (and potentially also 186.5 days) were excluded from the standardized series. However, these two operations eliminated only a small part of the variance; there was a substantial reduction in the variance only for ammonium nitrogen and total nitrogen at the inflow and outflow from a WWTP. The relationship between the inflow into a WWTP and the outflow from a WWTP for the concentrations and pollution loads was described by simple transfer functions (SISO models) and more complicated transfer functions (MISO models). A simple transfer function (SISO model) was employed to describe the relationship between the daily total precipitation and the wastewater discharge.
Ownership concentration and bank risk (A study on banking sectors in Indonesia)

The purpose of this study is to test empirically the relationship between ownership concentration and risk taking by banks which are proxied by the CAR and LDR (li-quidity ratio). The study was motivated by the limited previous studies that analyze the structure of ownership in financial institutions and the weaknesses in sampling. Our analysis focused on Indonesia because this country has implemented the Basel Accord II standards successfully. This regulatory compliance is expected can control banking risk. Using data from 2009 until 2013 and panel data. We found that the ownership concentration become important determinants of bank liquidity. These findings are expected to provide policy guidance for regulators, especially relating to the ownership structure of the bank. However, the ownership concentration proved to be involved in the management decision to risk taking in banks.
EXPERIMENTAL STUDY OF DUNE BUILDING WITH SAND FENCES

In 1957 the State of North Carolina, in cooperation with the Beach Erosion Board and the Wilmington District of the Corps of Engineers undertook an experimental dune building study on the Outer Banks of North Carolina. The experimental study consists of the construction of various types and arrangements of sand fences to determine the fence type and arrangement most effective in building a dune by trapping windblown sand. Four miles of experimental fencing were constructed in 1960. During the following year, four sets of profiles were made to determine the sand accumulation of the fences and a rather intermittent wind record was made in the area. The performance of the various fence types and arrangements has been compared and some conclusions have been reached concerning the best fence type and arrangement.
Influence of wheat populations arrangement on growth characteristics and grain yield

The arrangement of plants in paired spacing is one of the management practices being used in some crops resulting in increased yield. Aiming to evaluate the arrangements and plant density on agronomic characteristics, yield components and yield of two wheat cultivars, one experiment was carried out on a Haplic Cambisol Tb typical dystrophic soil, with two cultivars, in the city of Ponta Grossa, PR,. The design experimental was randomized blocks in a factorial design 2×4, with four replications. The treatments consisted of two plant arrangements (single and paired spacing) and four plant densities (45, 60, 75 and 90 plants m-1), applied in two wheat cultivars (Marfim and BRS-Tangara). At Paired spacing the number of spikes per square meter and yield were lower than single spacing, even with higher grain weight in both wheat cultivars. The paired spacing did not result in increased yield for both wheat cultivars. Key words: Triticum aestivum, tillage, paired spacing.
Drought Risk Mapping in East Nusa Tenggara Indonesia Based on Return Periods

Drought has been one of the major causes of disaster in Indonesia. The Regional Disaster Management Agency (BPBD) of East Nusa Tenggara (hereafter denoted as NTT) Province in Indonesia has reported that there were 20 districts in NTT affected by drought in 2015. This study aims to map drought risk in NTT by using the Standardized Precipitation Index (SPI). The study is carried out by examining daily rainfall data recorded by several meteorological stations in NTT within the period of 1999-2015. The results of SPI analysis showed that NTT has experienced about 25 months of drought events within the periods of 1999 to 2015. This reseach estimated the drought duration as well as the magnitude based on return periods of 5 years, 25 years and 50 years, as the basis of mappring the drought risk. The mapping results showed that Gewayantana is a district with the longest drought duration and strongest drought magnitude for all specified return periods. Meanwhile, Komodo and Frans Sales Lega districts are two regions with the lowest risk indicated by shortest drought duration and lowest magnitude compared to the others. The longest drought duration are mostly started in November.
Structural, biostratigraphic and petrographic evaluation of the Upper Cretaceous red marlstones and underlying granitoids from the borehole HPJ-1 Jašter near Hlohovec (Považský Inovec Mts., Slovakia)

The article provides the first results of analyses of the core material from the borehole HPJ-1 Jašter, located north of Hlohovec in the southern Považský Inovec Mts. (Western Carpathians, Slovakia). The main aim of the borehole was to determine the thickness and characteristics of sedimentary sequence of the Upper Cretaceous Horné Belice Group in a poorly exposed area and to reach its possible substratum. In the initial interval 0–45.8 m, the borehole penetrated deformed sequence of red and pink pelagic marly limestones and marlstones containing planktonic foraminifera. The drilled sediments are of the Late Cenomanian (45.5–41.5 m) and Middle Turonian – Santonian (41.5–34 m) age in the lower part of the sedimentary sequence. Stronger alteration and tectonic overprint of the uppermost interval (34–0 m) prevented a successful biostratigraphic age determination. The lower part of the borehole profile between 45.8–75.5 m is formed by pre-Alpine biotite granodiorites, which are separated from the overlying sedimentary sequence by a normal fault. Several possible interpretations of the tectonic position of the Upper Cretaceous complexes are discussed.
Conversion of Hyrcanian degraded forests to plantations: Effects on soil C and N stocks

Hyrcanian forest ecosystem is considered to be one of the most important natural deciduous forests in the world. Today, these forests are being devastated by human activities. So there have been many plantation establishments with endemic species in degraded forests of this area. But the effects of such conversions on soil C and N stocks and nutrients are still unknown. We investigated the effects of conversion of a degraded natural forest to Alnus subcordata . L, Acer velutinum . Boiss and Cupressus sempervirens. var.horizontalis plantations on soil C and N stocks and nutrients after 18 years. The studied stands are located in the county of Chamestan in the province of Mazandaran, Iran. Some of soil chemical and physical properties including available nutrient concentrations (Ca, Mg, P and K) and total N and organic C stocks in the soil were determined in three soil depths (0-15 cm, 15-30 cm and 30-50 cm). Soil available nutrients were higher under plantation stands compared to the degraded natural forest except for soil available K which decreased under A. subcordata plantation. We expect increasing the soil nutrient improvement with increasing the age of plantation stands. A. velutinum and C. sempervirens had increased soil C and N stocks but A. subcordata decreased soil C stock and increased soil N stock in comparison to the degraded natural forest. These results indicate that conversion of degraded forests with appropriate species can significantly improve soil C stocks, helping to mitigate the negative impacts of the greenhouse effect.
Wheat Flour Fortification With that of Defatted Seed of Citrulluslanatus (Cucurbitaceae): Effects on Organs Biometry

This study used to determine the effects of wheat flour fortification with that of defatted seed of Citrulluslanatus(Cucurbitaceae)on organ biometry.Thirty rats (30) team up into five per group were fed during 14 days with the six diets prepared: Diet made with casein (RTC); diet containing classic bread (RPC) and diets based on bread in which the wheat flour has been substituted by defatted seed flour of Citrulluslanatus(RPFd) at different proportions 5 % (RPFd5); 10% (RPFd10); 15 % (RPFd15); 20% (RPFd20). After the end of the experimental period, animals were sacrificed and kidney, liver, stomach, ileum and spleen were removed and weighted.Result showed that relative kidney weight of rats fed with RTC (0.84±0.08) and RPC (0.90±0.05) were significantly higher (p ≤ 0.05) than that of rats fed with RPFd (0.69±0.04 to 0.75±0.02). Relative weight of the other organs of rats fed with RPFd (0.24±0.11to 0.28±0.06) do not show a significant difference(p ≥ 0.05) when compared to that of rats fed with RTC and RPC. This study suggested that except for kidney, the wheat flour fortification with that of defatted seed of Citrullus lanatushave not effects on the biometry of others organs.
Influence of air temperature on proteinase activity and beverage quality in Coffea arabica

Fruits were collected from trees of Coffea arabica cv. Obata grown at Mococa and Adamantina in Sao Paulo State, Brazil, which are regions with marked differences in air temperature that produce coffee with distinct qualities. Mococa is a cooler location that produces high-quality coffee, whereas coffee from Adamantina is of lower quality. The amino acid and protein contents, amino acid profile, and proteinase activity and type in endosperm protein extracts were analysed. Proteinase genes were identified, and their expression was assayed. All results indicate that temperature plays a role in controlling proteinase activity in coffee endosperm. Proteinase activity was higher in the endosperm of immature fruits from Adamantina, which was correlated with higher amino acid content, changes in the amino acid profile, and increased gene expression. Cysteine proteinases were the main class of proteinases in the protein extracts. These data suggest that temperature plays an important role in coffee quality by altering nitrogen compound composition.
First record of non-indigenous Paracaprella pusilla Mayer, 1890 (Crustacea: Amphipoda) in the Northern Tropical East Pacific

Despite the large number of biological invasion studies, little is known about non-indigenous caprellids in the eastern Pacific. This study represents the first record of Paracaprella pusilla Mayer, 1890, an invasive species, in the northern tropical east Pacific (NTEP) region. Caprellids were collected from June 2013 to March 2014 on fouling substrates (mainly macroalgae, sponge, and bryozoans) associated with artificial structures at four sites from the Mexican Pacific. Marinas, sheltered waters, and aquaculture farms appeared to function as caprellid nurseries and may act as distribution points to other localities. P. pusilla inhabited a wide range of artificial structures, which appears to increase their survival success and may facilitate their dispersal to new locations in the eastern Pacific Ocean.
Customer Lifetime Value and RFM Data: Accounting Your Customers: One by One

A customer behavior model that permits the estimation of customer lifetime value (CLV) from standard RFM data in "non-contractual" setting is developed by extending the hierarchical Bayes (HB) framework of the Pareto/NBD model (Abe 2008). The model relates customer characteristics to frequency, dropout and spending behavior, which, in turn, is linked to CLV to provide useful insight into acquisition. The proposed model (1) relaxes the assumption of independently distributed parameters for frequency, dropout and spending processes across customers, (2) accommodates the inclusion of covariates through hierarchical modeling, (3) allows easy estimation of latent variables at the individual level, which could be useful for CRM, and (4) provides the correct measure of errors. Using FSP data from a department store and a CD chain, the HB model is shown to perform well on calibration and holdout samples both at the aggregate and disaggregate levels in comparison with the benchmark Pareto/NBD-based model. Several substantive issues are uncovered. First, both of our datasets exhibit correlation between frequency and spending parameters, violating the assumption of the existing Pareto/NBD-based CLV models. Direction of the correlation is found to be data dependent. Second, useful insight into acquisition is gained by decomposing the effect of change in covariates on CLV into three components: frequency, dropout and spending. The three components can exert influences in opposite directions, thereby canceling each other to produce less effect as the total on CLV. Third, not accounting for uncertainty in parameter estimate can cause large bias in measures, such as CLV and elasticity. Its ignorance can potentially have a serious consequence on managerial decision making.
Pattern of Adverse Drug Reactions Due to Cancer Chemotherapy in aTertiary Care Teaching Hospital in Eastern India

Introduction: Adverse drug reactions (ADRs) are a global problem adding to the economic burden of the society. Anti-cancer drugs are prone to cause ADRs and there is lack of pharmacovigilance data on such drugs. Therefore the present study was undertaken to monitor suspected ADRs in the radiotherapy unit of a tertiary care teaching hospital in Eastern India. Materials and methods: The present study was done in the Radiotherapy Department of a tertiary care teaching hospital in Eastern India from March, 2012 to August, 2012 among the patients receiving cancer chemotherapy. It was a hospital based prospective observational study. ADRs were documented in Suspected Adverse Drug Reaction reporting form designed by Centre for Drug Standard Control Organizationand causality assessment was done using Naranjo scale. Results: 87% of the total patients receiving cancer chemotherapy developed ADRs. Most common ADRs found were nausea and vomiting followed by neutropenia. Cisplatin, Cyclophosphamide, 5-Fluoro uracil, Paclitaxel and Adriamycin were common drugs causing ADRs. 62% of the ADRs were probable according to Naranjo scale. Conclusion: The cancer chemotherapeutic drugs are associated with varied adverse effects. However, early detection of drug toxicity helps to modify the doses or the drug regimen to minimize toxic effects.
Effect of processing on mechanically alloyed and spark plasma sintered Al-Al 2 O 3 nanocomposites

Metal matrix nanocomposites are advanced materials developed using ceramic nanoreinforcements and nanocrystalline metal matrices. These composites have outstanding properties and high potential for large number of functional and structural applications. In this work, nanocrystalline aluminium and Al-Al2O3 nanocomposites were synthesised using mechanical alloying and consolidated through spark plasma sintering technique. Scanning electron microscopy, X-ray diffraction, and mapping were used to characterize the powders and sintered samples. Density and hardness of sintered samples were measured using densimeter and hardness tester, respectively. It was found that milling of pure aluminium for 24 h reduced its crystallite size to less than 100 nm. For Al-Al2O3 nanocomposites, milling for 24 h decreased the crystallite size of the aluminium phase and resulted in uniform dispersion of the reinforcement. Sintering of the synthesised powders led to grain growth. Al2O3 contributed to growth inhibition when samples were sintered for 20 minutes and improved the hardness but reduced densification. The Al-10 vol.% Al2O3 nanocomposite had the highest Vickers hardness value of 1460 MPa.
Simulation of the Cuttings Cleaning During the Drilling Operation

Problem statement: Oil well cleaning is the ability of a drilling fluid to suspend and transport drilled cuttings from the down hole (bit face) to the surface. The cleaning performance was affected by many factors such as fluid viscosity, annular flow velocity, angle of inclination and drill cuttings size and shape and. Approach: Navier-Stoke equations, the continuity equation and the power law of non-Newtonian viscosity model were adopted to establish the mathematical model of the cutting transport process in the annulus of the well. The constants of the power law model were evaluated experimentally for three different mud types. The CFD simulation to solve the governing equations was carried out by using FLUENT commercial code. The specifications of the particles, the pumping head and feeding conditions were obtained from a drilling site in Sudan. Results: Simulation of the mud flow in the annulus had shown that in spite of the laminar nature of the flow, the velocity profile was flattening over wide area of the annulus. Such condition was referred to as fog flow and was preferable to produce uniform drag distribution to lift the particles without rotation during the transportation process. The analysis had been conducted for various mud charging rates ranging from 600-900 GPM, in 30° diverted orientation well. The investigation of cuttings size was conducted for 2.54, 4.45 and 7 mm. Also, the effect of the cuttings shape with 1, 0.9 and 0.85 was investigated and it was found that higher sphereicity have better cleaning efficiency. Conclusion: The analyses revealed that for 30° diverted orientation; the effective cleaning performance was achieved when the drilling mud charging was higher than 800 GPM for all types of tested cuttings. The simulation results revealed that there was a significant effect of the cuttings size on the cuttings transport. Fine particles are the easiest to clean out.
Energy savings evaluation for dry-cooler equipped plants in shopping mall buildings

In the present paper the possible energy savings achievable by means of dry coolers adoption in cooling plants serving shopping mall buildings has been carried out. In these buildings, could happens that, due to internal gains caused by occupancy, lighting, and electrical devices, or because of solar radiation entering through the large skylights on the aisle, some zones have to be cooled also during the middle and the winter seasons. The aim of this work is the evaluation of the energy saving, reachable when a water indirect free cooling system is integrated into a traditional cooling equipment in a shopping mall. Depending on outside climate conditions, the dry-cooler units could be used alternatively to cool down the refrigerant flow, or the water supplied to fan coils, achieving in such a way an indirect free cooling; so, the proposed system allows to turn off the chiller. By means of energy simulations, electrical energy saving in different locations has been evaluated. Simulations results allowed a comparison between a traditional plant and a plant equipped with a dry-cooler. These simulations were useful to evaluate the influence of weather conditions in the dry cooler integration
A stopband filter design using a 1D non‐periodic defected ground structure

The one‐dimensional (1D) defected ground structure (DGS) is used to control the cut‐off frequency characteristic. In this paper three non‐periodic filters are built, in order to show the versatility of DGS. Five unit cells of different shape with the same attenuation pole frequency were combined in each filter. The frequency response is essentially the same as in the case of periodic filters with equal square unit cells. © 2003 Wiley Periodicals, Inc.

Consumption and Debt Dynamics with (Rarely Binding) Borrowing Constraints

This paper examines consumption and savings dynamics in a standard model of incomplete markets. Existence of equilibrium requires the imposition of exogenous debt limits but these are often ignored because of the computational difficulties that arise in models with occasionally binding constraints. I claim that borrowing constraints have a significant qualitative and quantitative effect on equilibrium allocations even if they rarely bind. Contrary to standard results in the literature, debt exhibits mean reversion, consumption responds strongly to idiosyncratic income shocks and interest rates respond to both aggregate and idiosyncratic innovations in income. The implication is that market incompleteness can generate much lower consumption correlations than was previously thought.
