Customer Incivility and Counterproductive Work Behaviors in Egyptian Healthcare Service: Does Workplace Social Support Buffer?

Employees in the healthcare industry encounter a high volume of challenging and stressful events, particularly in light of global health disasters. Customer incivility is frequently occurring in the healthcare industry which severely depletes both psychological and physical resources. Anecdotal evidence suggests that customer incivility leads to counterproductive work behaviors (CWB). Based on the assumptions of the conservation of resources theory and stressor-strain framework, this study demonstrates empirically the impact of customer incivility on the two most common forms of CWB among Egyptian healthcare professionals. Moreover, this work sheds a spotlight on whether workplace social support (WSS) may buffer against the damaging consequences of customer incivility. Structural equation modeling was used to analyze the data collected from 343 professionals employed in public—government and parastatal—hospitals in Dakahlia Governorate in Egypt. The findings demonstrate that customer incivility increases both interpersonal-targeted and organizational-targeted CWB. However, the role of WSS as a protective mechanism against the adverse consequences of customer incivility remains contingent on the form of CWB.
Evaluating the Impact of Time-to-Collision Constraint and Head Gaze on Usability for Robot Navigation in a Corridor

Navigation of robots among humans is still an open problem, especially in confined locations (e.g. narrow corridors, doors). This article aims at finding how an anthropomorphic robot, like a PR2 robot with a height of 1.33 m, should behave when crossing a human in a narrow corridor in order to increase its usability. Two experiments studied how a combination of robot head behavior and navigation strategy can enhance robot legibility. Experiment 1 aimed to measure where a pedestrian looks when crossing another pedestrian, comparing the nature of the pedestrian: human or a robot. Based on the results of this experiment and the literature, we then designed a robot behavior exhibiting mutual manifestness by both modifying its trajectory to be more legible, and using its head to glance at the human. Experiment 2 evaluated this behavior in real situations of pedestrians crossing a robot. The visual behavior and user experience of pedestrians were assessed. The first experiment revealed that humans primarily look at the robot's head just before crossing. The second experiment showed that when crossing a human in a narrow corridor, both modifying the robot trajectory and glancing at the human is necessary to significantly increase the usability of the robot. We suggest using mutual manifestness is crucial for an anthropomorphic robot when crossing a human in a corridor. It should be conveyed both by altering the trajectory and by showing the robot awareness of the human presence through the robot head motion. Small changes in robot trajectory and manifesting robot perception of the human via a user identified robot head can avoid users' hesitation and feeling of threat.
Resiniferatoxin: Nature’s Precision Medicine to Silence TRPV1-Positive Afferents

Resiniferatoxin (RTX) is an ultrapotent capsaicin analog with a unique spectrum of pharmacological actions. The therapeutic window of RTX is broad, allowing for the full desensitization of pain perception and neurogenic inflammation without causing unacceptable side effects. Intravesical RTX was shown to restore continence in a subset of patients with idiopathic and neurogenic detrusor overactivity. RTX can also ablate sensory neurons as a “molecular scalpel” to achieve permanent analgesia. This targeted (intrathecal or epidural) RTX therapy holds great promise in cancer pain management. Intra-articular RTX is undergoing clinical trials to treat moderate-to-severe knee pain in patients with osteoarthritis. Similar targeted approaches may be useful in the management of post-operative pain or pain associated with severe burn injuries. The current state of this field is reviewed, from preclinical studies through veterinary medicine to clinical trials.
Long‐term climate variations in China and global warming signals

[1] In this work, the authors analyze the observed long-term variations of seasonal climate in China and then investigate the possible influence of increases in greenhouse gas concentrations on these variations by comparing the observations with the simulations of the second phase of the Coupled Model Intercomparison Project (CMIP2). The long-term variations of precipitation and temperature in China are highly seasonally dependent. The main characteristic of summer precipitation in China is a drying trend in the north and a wetting trend in the central part. The precipitation in winter shows an increasing trend in southern and eastern-central China. Interesting features have also been found in the transitional seasons. In spring, precipitation variations are almost opposite to those in summer. In autumn the precipitation decreases in almost the whole country except for the middle and lower reaches of the Yangtze River Valley. In addition, the seasonality of precipitation has become slightly weaker in recent decades in southern and eastern China. Pronounced warming is observed in the entire country in winter, spring, and autumn, particularly in the northern part of China. In summer a cooling trend in central China is particularly interesting, and cooling (warming) trends generally coexist with wetting (drying) trends. The correlativity between precipitation and temperature variations is weak in spring, autumn, and winter. It has also been found that the long-term climate variations in winter and summer in China may be connected to the warming trend in the sea surface temperature of the Indian Ocean. A comparison between the observed seasonal climate variations and the CMIP2 simulations of 16 models indicates that the observed long-term variations of winter, spring, and autumn temperature in China may be associated with increases in greenhouse gas concentrations. However, such a connection is not found for the summer temperature. The tremendous uncertainties among the models in precipitation simulations make it difficult to link the precipitation variations to global warming.

SENSITIVITY ANALYSIS, CALIBRATION, AND VALIDATIONS FOR A MULTISITE AND MULTIVARIABLE SWAT MODEL 1

The ability of a watershed model to mimic specified watershed processes is assessed through the calibration and validation process. The Soil and Water Assessment Tool (SWAT) watershed model was implemented in the Beaver Reservoir Watershed of Northwest Arkansas. The objectives were to: (1) provide detailed information on calibrating and applying a multisite and multivariable SWAT model; (2) conduct sensitivity analysis; and (3) perform calibration and validation at three different sites for flow, sediment, total phosphorus (TP), and nitrate‐nitrogen (NO3‐N) plus nitrite‐nitrogen (NO2‐N). Relative sensitivity analysis was conducted to identify parameters that most influenced predicted flow, sediment, and nutrient model outputs. A multi objective function was defined that consisted of optimizing three statistics: percent relative error (RE), Nash‐Sutcliffe Coefficient (RNS2), and coefficient of determination (R2). This function was used to successfully calibrate and validate a SWAT model of Beaver Reservoir Watershed at multi‐sites while considering multivariables. Calibration and validation of the model is a key factor in reducing uncertainty and increasing user confidence in its predictive abilities, which makes the application of the model effective. Information on calibration and validation of multisite, multivariable SWAT models has been provided to assist watershed modelers in developing their models to achieve watershed management goals.
Disturbance of microsites and early tree regeneration after windthrow in Swiss mountain forests due to the winter storm Vivian 1990

In 1990, the catastrophic storm Vivian created extensive windthrows, particularly in some mountain forests of the Swiss Alps. We have since been observing the vegetation succession and the tree regeneration in uncleared and cleared windthrown stands on four study sites in mountain forests at altitudes of 900 to 1600 m a.s. l. On the study sites, microsites were mapped and, subsequently, 236 permanent quadrats were installed. At two-year intervals, data were collected on plant and moss species between 1992 and 2000. Vegetation dynamics were analysed with respect to the succession of microsites, disturbance types, treatments and years of tree seed germination. Vegetation cover increased in all quadrats observed independent of microsites and types of disturbance. On most of the microsites, Rubus idaeus increased in frequency and in cover during the first 10 years after the windthrow. Grasses such as Calamagrostis villosa, Agrostis capillaris and Avenella flexuosa also increased. The most abundant regenerating tree species were Picea abies, Acer pseudoplatanus and Sorbus aucuparia. Seedlings and saplings were small or absent in tall herb communities. Advance regeneration was of predominant importance on all study sites. Post-windthrow regeneration was greatest on disturbed microsites. The regeneration density of the whole study area (projected from the permanent quadrats) ranged between 2000 and 45 000 seedlings and saplings per ha. This indicates considerable differences in recruitment conditions in mountain forests after windthrow. Disturbance to tall herb-dominated gaps in mountain forests favours seedling recruitment during the early succession after the windthrow. Disturbance effects caused by timber harvest after a windthrow resulted in a large density of post-windthrow regeneration that may compensate, at least partly after only 10 years, for the advance regeneration destroyed.
Kinematic data on major Variscan strike-slip faults and shear zones in the Polish Sudetes, northeast Bohemian Massif

The still highly disputable terrane boundaries in the Sudetic segment of the Variscan belt mostly seem to follow major strike-slip faults and shear zones. Their kinematics, expected to place important constraints on the regional structural models, is discussed in some detail. The most conspicuous is the WNW–ESE Intra-Sudetic Fault Zone, separating several different structural units of the West Sudetes. It showed ductile dextral activity and, probably, displacement magnitude of the order of tens to hundreds kilometres, during late Devonian(? ) to early Carboniferous times. In the late Carboniferous (to early Permian? ), the sense of motion on the Intra-Sudetic Fault was reversed in a semi-brittle to brittle regime, with the left-lateral offset on the fault amounting to single kilometres. The north–south trending Niemcza and north-east–southwest Skrzynka shear zones are left-lateral, ductile features in the eastern part of the West Sudetes. Similarly oriented (northeast–southwest to NNE–SSW) regional size shear zones of as yet undetermined kinematics were discovered in boreholes under Cenozoic cover in the eastern part of the Sudetic foreland (the Niedźwiedź and Nysa-Brzeg shear zones). One of these is expected to represent the northern continuation of the major Stare Mesto Shear Zone in the Czech Republic, separating the geologically different units of the West and East Sudetes. The Rudawy Janowickie Metamorphic Unit, assumed in some reconstructions to comprise a mostly strike-slip terrane boundary, is characterized by ductile fabric developed in a thrusting regime, modified by a superimposed normal-slip extensional deformation. Thrusting-related deformational fabric was locally reoriented prior to the extensional event and shows present-day strike-slip kinematics in one of the sub-units. The Sudetic Boundary Fault, although prominent in the recent structure and topography of the region, was not active as a Variscan strike-slip fault zone. The reported data emphasize the importance of syn-orogenic strike-slip tectonics in the Sudetes. The recognized shear sense is compatible with a strike-slip model of the northeast margin of the Bohemian Massif, in which the Kaczawa and Góry Sowie Units underwent late Devonian–early Carboniferous southeastward long-distance displacement along the Intra-Sudetic Fault Zone from their hypothetical original position within the Northern Phyllite Zone and the Mid-German Crystalline High of the German Variscides, respectively, and were juxtaposed with units of different provenance southwest of the fault. The Intra-Sudetic Fault Zone, together with the Elbe Fault Zone further south, were subsequently cut in the east and their eastern segments were displaced and removed by the younger, early to late Carboniferous, NNE–SSW trending, transpressional Moldanubian–Stare Mesto Shear Zone.
Migration and sedimentology of longshore sandwaves, Long Point, Lake Erie, Canada

This paper describes the formation, migration and sedimentology of sandwaves along the distal end of Long Point, a 40 km long spit in Lake Erie. Some seven to nine sandwaves occur in a zone over the last 14 km of the spit. They are characteristically 50–100 m wide at the downdrift end, range in length from 350 m to > 1500 m and migrate alongshore at rates that are typically 100–300 m year−1. Measurements over a 7‐year period show two forms of alongshore sandwave migration: (1) a migratory jump; and (2) downdrift accretion. The migratory jump is commonly 200–500 m year−1 and results from the onshore migration and welding of an inner nearshore bar to the downdrift end of the sandwave. This in turn leads to emergence of the bar over a distance of several hundred metres downdrift of the sandwave and isolation of the trough landward of the bar. Infilling of the trough abstracts large volumes of sediment from the local sediment transport system and may affect movement of the sandwave in the following year or movement of the next sandwave downdrift. Downdrift accretion commonly results in migration of 50–150 m year−1 and results from the refraction of waves around the distal end of the sandwave and episodic accretion of small swash bars. This mechanism occurs less frequently and appears to reflect a local condition of lower sediment abundance, often triggered by a large migratory jump in the previous year. The process of bar emergence and infilling produces a distinct suite of sedimentary structures associated with the infilling of the landward trough and building of the sandwave berm. The initial shoreline perturbation that generates the sandwave results from onshore migration and welding of inner nearshore bars, and the development and growth of the sandwaves is promoted by refraction of highly oblique waves.
The Effects of Bioturbation on the Fabric of Shale

ABSTRACT X-radiography and scanning electron microscope analyses of shales from diverse sedimentary environments reveal wide variations in macro-and microfabrics attributed to the degree of bioturbation. These fabrics provide clues about the physical condition of the sediment substrate at the time of clay deposition and the relationship between bioturbation activity and the sedimentary environment. Organic-rich shales from anoxic environments are unbioturbated and characterized by fine lamination and a microfabric of parallel clay flakes. Two fabric types were found in shales formed under oxic conditions--highly bioturbated and indistinctly bedded. Fabric in shales subjected to considerable bioturbation is recognized by a homogeneous, gray tone in an X-radiograph and by a random microfabric in a scanning electron micrograph. This fabric is also very similar to mudstones formed from lithified flocculated clay; however, it does not possess the stepped domains or stepped cardhouse fabric of the latter. Indistinctly bedded shale possesses remnant original lamination and preferred particle orientation indicative of less intense bioturbation. The fabric types are useful in determining whether the sediment substrate was a soupground, softground, or firmground, as well as indicating the amount and intensity of biogenic activity during sediment deposition.
‘Marks of extreme violence': Charles Darwin's geological observations at St Jago (São Tiago), Cape Verde islands

Abstract The first stop on Charles Darwin's famous voyage around the world in HMS Beagle was at Porto Praya (Praia), the principal town on the island of St Jago (São Tiago) in the Cape Verde archipelago. From 16 January to 8 February 1832, Darwin enjoyed his first substantive opportunity to study the natural history of an exotic place. Darwin himself regarded this occasion as a significant turning point in his life because, according to his autobiography, it was here that he decided to research and publish a book on the geology of the places visited on the voyage. He also recalled that it was here, the very first port call, that convinced him of the ‘wonderful superiority’ of Charles Lyell's uniformitarian geology over the doctrine of successive cataclysms that he had been taught in England. Later commentators have generally accepted this account, which is significant for understanding the intellectual background to the Origin of Species, at face value. In this paper we reconstruct some of Darwin's observations at St Jago based on his contemporaneous notes and diary, and in the light of our own visit made in January 2002. We find little evidence to substantiate the claim that he interpreted the geology in Lyellian terms at the time. Instead, he formulated a theory involving a great cataclysm to explain the dramatic scenery in the island's interior. He speculated that a torrent of water had carved the main valleys of the island, leaving deposits of diluvium in their beds. It is indisputable that Darwin came to embrace gradualist thinking enthusiastically during the voyage. Some of his observations made on St Jago, especially relating to uplift of the coast, were instrumental in this change of view, but the conversion was gradual, not sudden. His later published works make no mention of his original catastrophist interpretations.
On the Contribution of Longwave Radiation to Global Climate Model Biases in Arctic Lower Tropospheric Stability

AbstractPrevious research has found that global climate models (GCMs) usually simulate greater lower tropospheric stabilities compared to reanalysis data. To understand the origins of this bias, the authors examine hindcast simulations initialized with reanalysis data of six GCMs and find that four of the six models simulate within five days a positive bias in Arctic lower tropospheric stability during the Arctic polar night over sea ice regions. These biases in lower tropospheric stability are mainly due to cold biases in surface temperature, as very small potential temperature biases exist aloft.Similar to previous research, polar night surface temperature biases in the hindcast runs relate to all-sky downwelling longwave radiation in the models, which very much relates to the cloud liquid water. Also found herein are clear-sky longwave radiation biases and a fairly large clear-sky longwave radiation bias in the day one hindcast. This clear-sky longwave bias is analyzed by running the same radiation tra.
Influence of executive functioning and emotional regulation on effective career choice

Although emotional management and executive functioning have been widely associated with effective decision making, not much attention has been paid to their role in vocational decision making. This study analyzed the relationship between insecurity in career choice, executive functioning, and emotion regulation in university students. Results show how executive dysfunction significantly predicted insecurity in vocational choice. Its mediating role between emotional management and the academic-vocational decision-making process was also confirmed. Our findings contribute to the understanding of vocational choice in youth and suggest the need to consider both variables in guidance programs, to prevent subsequent dissatisfaction with the vocational decision.
Carbide Ripened Fruits- A Recent Health Hazard

Large amount of tropical fruits are produced in this subcontinent including Bangladesh. But in recent times consumption of fruits becomes extremely hazardous due to artificial ripening of fruits by different toxic chemical agents. Normally fruits produce a ripening hormone ethylene that induces the natural process of maturation. This process is artificially accelerated by using different chemicals of which calcium carbide is the commonest. Calcium carbide in contact with moisture produces acetylene which is an analogue of natural ripening hormone ethylene. Acetylene is a highly reactive substance used mainly in welding and allied industries. Industrial grade calcium carbide also contains trace amounts of more toxic arsenic and phosphorous that converts the healthy fruits poisonous1.
Cross-Flow Turbine Design For Energy Production And Discharge Regulation

AbstractCross-flow turbines are very efficient and cheap turbines that allow a very good cost/benefit ratio for energy production located at the end of conduits carrying water from a water source to a tank. In this paper, a new design procedure for a cross-flow turbine working with a variable flow rate is proposed. The regulation of the head immediately upstream the turbine is faced by adopting a shaped semicircular segment moving around the impeller. The maximum efficiency of the turbine is attained by setting the velocity of the particles entering the impeller at about 2× the velocity of the rotating system at the impeller inlet. If energy losses along the pipe are negligible, the semicircular segment allows always a constant hydraulic head and a constant velocity at the impeller inlet, even with variable flow rate. The decrease of the turbine efficiency along with the inlet surface reduction is first investigated; a design methodology, using also computational fluid dynamics simulations, is then propos.
The Determinants of the Willingness to Be an Organ Donor

The total value of life lost due to death because of waiting for an organ transplant is greater than $4 billion annually in the United States, and the excess demand for organs has been increasing over time. To shed light on the factors that impact the willingness to donate an organ, we analyze data from the United States and the European Union. The rate of willingness to donate an organ is 38 % among young adults in the U.S., and it is 42 % in Europe. Interesting similarities emerge between the U.S. and Europe regarding the impact of gender, political views and education on the willingness to donate. In the U.S. Blacks, Hispanics and Catholics are less likely to donate. In Europe, individuals who reveal that they are familiar with the rules and regulations governing the donation and transplantation of human organs are more likely to donate. In both data sets individuals who had some encounter with the health care sector %u2013either through a recent emergency room visit (in the U.S.), or perhaps because of a long-standing illness (in the E.U), are more likely to become organ donors. Mother%u2019s education has a separate positive impact.
