The Impact of Social Media Usage on Marketing Performance via Innovation: An Empirical Study on Service Firms in Egypt

Field: Business, Management and Accounting (Social Sciences)

With the growing intensified competition and development of the service sector, innovation has become vital dimension for firms to enjoy competitive advantages and yield positive outcomes on the economy. The use of social media (SM) as one of the service firm communication tools fosters innovation and has always been of critical importance to both academia and practice. Thus, this study focuses on the impact of SM usage based on both knowledge exploration and exploitation on the marketing performance via the most widely accepted four innovation types in past literature, which consist of product, process, marketing and organizational innovation in the Egyptian private service sector. Questionnaires were distributed electronically to gather data. Data gathered from 385 private service firms from the top management level. Data has been analyzed via Structural Equation Modelling (SEM), AMOS 22. Results indicated that SM usage has a significant positive direct impact on all types of innovation with varying relative effects. Additionally, it has been found that marketing innovation played the greatest direct and positive impact on the marketing performance, followed by the product innovation, however, the process innovation has been found to have negative impact on the marketing performance. While the organizational innovation does not directly impact the marketing performance. This study contributes to the literature by highlighting on the SM usage and the vital types of innovation that lead to higher marketing performance in the service sector which needs more attention from service marketing managers. Also, this study helps the service providers in the private service firms to focus on the significance role of SM in exploring and exploiting knowledge especially from customers to innovate in a better way to consequently enhance the marketing performance.

Tactile and proximity measurement by 3D tactile sensor using self-capacitance measurement

Field: Engineering (Physical Sciences)

In this paper, we propose a 3D tactile sensor using self-capacitance measurement for robot. The proposed sensor consists of the two electrodes (E 1 and E 2 ) and elastic body. The capacitance between E 1 or E 2 and GND is measured by switching between E 1 and E 2 . The capacitance between E 1 and GND is used to detect the object before contact (proximity range) and to discriminate the material on contact. The capacitance between E2 and GND (E 1 ) is used to detect the indentation on contact. The sensor is attached to the robot surface, and can detect object both before and after contact (3D range). This technique may be applicable to proximity and tactile sensor for robot.
Ehrlichial DNA Amplified from Ixodes ricinus (Acari: Ixodidae) in France

Field: Immunology and Microbiology (Life Sciences)

Granulocytic ehrlichia 16S rDNA was amplified for the 1st time from an Ixodes ricinus (Linne) tick collected in Europe. Sequence analysis of polymerase chain reaction products from the 16S rRNA gene demonstrated the organism from which it originated to be closely related to the agent of human granulocytic ehrlichiosis, an emerging disease that was recently described in the United States; Ehrlichia phagocytophila, the agent of tick-borne fever of ruminants in Europe; and Ehrlichia equi. the agent of the worldwide equine granulocytic ehrlichiosis. These granulocytic ehrlichiae have been associated with Ixodes spp. ticks that may act as vectors. It remains to be determined if each of these granulocytic ehrlichiae, that may constitute variants of the same species, is responsible for a specific disease in animals and in humans.

Beverage‐specific situational norms: Evidence from the Dutch electronic appropriate beverage task

Field: Psychology (Social Sciences)

Abstract Introduction and Aims By the time young adolescents initiate alcohol consumption they have firmly established attitudes, expectations and beliefs about alcohol and its effects. To further unravel the origins of this knowledge in childhood, we aim to address Dutch children's knowledge of the types of alcoholic beverages adults typically consume in certain situational contexts (i.e. their knowledge of beverage‐specific situational norms). Design and Methods A total of 329 children (4–8 years old) completed the Dutch electronic Appropriate Beverage Task at three‐time points (2015, 2016, 2017). Three‐level regression models were estimated examining whether children's beverage‐specific situational norms depend on the gender of the person displayed in the task, sex of the participant and whether there were any beverage‐specific changes over time. Results Beverage‐specific findings seem to be robust across the appropriateness of the situation. Beer was the most frequently attributed alcoholic beverage overall and across the common drinking situations. White wine was attributed significantly more to females in the task. Beer, red wine and champagne were attributed significantly more to males. Attributions of individual alcoholic beverages did not change significantly over time. There were no significant differences between the participating boys and girls. Discussion and Conclusions Results suggest that 4–8‐year olds are yet to form knowledge of beverage‐specific situational norms. Independent of the situation, time and participants' sex, the gender of the person displayed in the task seemed to be more salient to children than situational or environmental indicators in determining consumption.
The Social Adjustment of Newcomers in Secondary School

Field: Social Sciences (Social Sciences)

Abstract Each year, a large number of children change residence and school. This paper examines the social experience of being a newcomer at secondary school, with special reference to the process of adjustment. It is based on a detailed longitudinal case study of 45 newcomers. Each was followed for 12 months, with the main source of data being seven in-depth interviews with each student, backed up by unscheduled interviews, school reports, teacher and peer-group comments and observations. Because the data show extensive similarity in newcomers' experiences–all must deal with a different curriculum, new teachers and the social world of other students–it is possible to construct a general three-stage map of the process of adjustment. This map has important implications for the guidance and counselling of such students.
Effect of oil, water and surfactant mixture on the physicochemical properties and transdermal delivery of finasteride-loaded microemulsions: evaluation and prediction using response surface methodology

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Introduction: Finasteride is an effective drug for the treatment of androgenetic alopecia by inhibition of type II 5α- reductase. However, oral administration finasteride has the undesirable systemic side effect about sexual dysfunction. Therefore topical delivery system of finasteride is a method to avoid this problem. Microemulsion (ME) is an interest delivery system for delivery of finasteride through the skin. The objective of this study was to investigate the effect of oil phase, water phase and surfactant mixture (Smix: surfactant and co-surfactant) on the physicochemical properties of finasteride-loaded microemusion. Methods: The pseudoternary phase diagrams were constructed to obtain the microemulsion area. Then the seven different ratios of microemulsion were selected to evaluate the physicochemical properties (droplet size, size distribution, conductivity and pH) by comparing between blank and finasteride-loaded microemulsion. The response surface method was used to predict the results by using computer program. The three finasteride- loaded microemulsion formulations with the same percentage of surfactant mixture were selected to study the in vitro skin permeation. Results: The pseudoterary phase diagram of microemulsion system with Smix at ratio 3:1 showed the largest area of microemulsion, therefore this system was selected to incorporate finasteride into the formulation. Finasteride did not affect the change in physicochemical properties of microemulsion. The in vitro skin permeation results indicated that the formulation with high concentration of water showed higher permeation flux than the formulation with low concentration of water. Conclusion: The prediction of finasteride-loaded ME by using response surface methodology showed the relationship between the amount of the composition in ME formulation and the physicochemical properties. This suggested that the optimal formulation can be developed for transdermal delivery of finasteride in treatment of androgenetic alopecia. However, other properties of the formulation, such as entrapment efficiency, skin retention, toxicity and stability of the formulation should be investigated.
The Evolution of Public Opinion Research and its Significance for the German-American Dialogue

Field: Social Sciences (Social Sciences)

In his monumental work, Walter Lippmann (1922) examined the problems inherent in understanding how citizens in a democratic society make their decisions on public issues. Writing in 1921, in the wake of the First World War, Lippmann questioned the ability of individuals to have sufficient knowledge to make informed judgements on complicated policy decisions. He argued that human beings make decisions based on their emotional prejudices. "We do not first see, and then define; we define first and then see .... In the great blooming, buzzing confusion of the outer world, we pick out what our culture has already defined for us and we tend to perceive that which we have picked out in the form stereotyped for us by our culture" (Lippmann 1997: 54).

An Evaluation of Population Projection Errors for Census Tracts

Field: Social Sciences (Social Sciences)

"In this article we evaluate the accuracy and bias of projections of total population and population by age group for census tracts in three counties in Florida. We use [U.S. census] data from 1970 and 1980 and several simple extrapolation techniques to produce projections for 1990; we then compare these projections with 1990 census counts and evaluate the differences. For the total sample, we find mean absolute errors of 17%-20% for the three most accurate techniques for projecting total population and find no indication of overall bias. For individual age groups, mean absolute errors range from 20%-29%." This is a revised version of a paper presented at the 1993 Annual Meeting of the Population Association of America.
Particulate Exposure at two Arkansas Racinos; Unsafe Environments?

Field: Health Professions (Health Sciences)

The purpose of this pilot project was to initiate data collection on secondhand smoke (SHS) for two racinos (racetrack casinos) exempted from Arkansas' 2006 Clean Indoor Air Act. Air quality was assessed during regular hours in sites open to the public. All measurements of fine particulates (PM2.5) within both facilities exceeded maximal safe EPA standards for an equivalent 24-hour average exposure. The exemptions as they stand, fail to protect all interested citizens.
Women prefer larger governments: female labor supply and public spending

Field: Economics, Econometrics and Finance (Social Sciences)

The increase in income per capita is accompanied, in virtually all countries, by two changes in the structure of the economy: an increase in the share of government spending in GDP and an increase in female labor force participation. This paper suggests that the changes in female labor force participation and government size are not just coincident in time, they are causally related. We develop a growth model with endogenous fertility, labor force participation and government size to illustrate this causal link. When government consumption and/or subsidies decrease the cost of performing household chores - including, but not limited to child rearing and child care - an increase in the female market wage leads to an increase in labor force participation by women and a demand for higher government spending. As women make the decision to work outside the home, they increase their demand for services typically provided by the government, such as education and health care, which, in turn, decrease the cost of home and family activities that are overwhelmingly performed by women. We show, for a wide cross-section of developed and developing countries, that higher female participation rates in the labor market are positively associated with larger governments. We investigate the causal link by instrumenting for female labor force participation with the prevalence of contraceptive methods and the relative price of household appliances. Female labor force participation is found to cause an increase in government size, with a 10 percent rise in the former leading to a 6.5 to 9 percent rise in the latter. This e.ect is stronger for government consumption than for government subsidies and is robust to the country sample, time period, and a set of controls in the spirit of Rodrik (1998).
Developing the coupled climate model ACCESS-ESM1.5 for the early Eocene

Field: Earth and Planetary Sciences (Physical Sciences)

We are currently developing the Australian community climate model ACCESS-ESM1.5 for deep time paleoclimate simulations. We are currently targeting the early Eocene (~55 Ma) and the Miocene climate optimum (~15 Ma); two warm intervals with high CO2 concentrations and strong polar amplification. The major challenge in adapting this model is to implement extensive changes to surface boundary conditions, including topography, vegetation, river runoff and ice sheets. The model has never previously been run outside of modern boundary conditions. We have developed new prototype simulations for each time period, and will present preliminary results for the Eocene and Miocene using ACCESS-ESM1.5. These simulations will be developed in parallel with simulations using the GFDL CM2.1 coupled climate model, which has been established as an efficient tool for reaching equilibrium paleoclimate scenarios.&#160;
Geostatistical approach to estimate car occupant fatalities in traffic accidents

Field: Earth and Planetary Sciences (Physical Sciences)

Despite the scientific and technological advances toward road crash prediction models, modelling road crashes in Brazil is a challenging task due to unreliable data and unavailability of essential information. Geostatistical approaches fit into this context as they not only incorporate the spatial factor, but also estimate variables in locations where they are not sampled. In order to contribute to this investigation and present geostatistics as a suitable tool in estimating road deaths, this study aimed to explore two different univariate interpolation methods to predict car occupant fatalities. In this study, we considered ordinary kriging and indicator kriging as such approaches. Analyses were held based on data from the state of São Paulo in Brazil. The results revealed a statistical outperformance in favor of indicator kriging, although spatial patterns found on kriging maps for both techniques indicated similarities in terms of hotspots. Furthermore, they were coherent with local aspects observed in the state, for instance those related to highway and vehicle characteristics.
CaSS: A Channel-aware Self-supervised Representation Learning Framework for Multivariate Time Series Classification

Field: Computer Science (Physical Sciences)

Self-supervised representation learning of Multivariate Time Series (MTS) is a challenging task and attracts increasing research interests in recent years. Many previous works focus on the pretext task of self-supervised learning and usually neglect the complex problem of MTS encoding, leading to unpromising results. In this paper, we tackle this challenge from two aspects: encoder and pretext task, and propose a unified channel-aware self-supervised learning framework CaSS. Specifically, we first design a new Transformer-based encoder Channel-aware Transformer (CaT) to capture the complex relationships between different time channels of MTS. Second, we combine two novel pretext tasks Next Trend Prediction (NTP) and Contextual Similarity (CS) for the self-supervised representation learning with our proposed encoder. Extensive experiments are conducted on several commonly used benchmark datasets. The experimental results show that our framework achieves new state-of-the-art comparing with previous self-supervised MTS representation learning methods (up to +7.70\% improvement on LSST dataset) and can be well applied to the downstream MTS classification.
THE DEMAND FOR EXCESS RESERVES, LIABILITY MANAGEMENT, AND THE MONEY SUPPLY PROCESS

Field: Economics, Econometrics and Finance (Social Sciences)

Commercial bank behavior is not adequately dealt with in existing macro models of the financial sector. The central role of a demand for excess reserves (or free reserves) function in models of the money supply process is particularly suspect. In this paper, it is argued that changes in commercial bank behavior induced by alterations in economic and financial conditions and various banking regulations, along with the central bank's approach to policy, have combined to alter the excess reserve function and the relationship between bank reserves and the money supply. Empirical work presented suggests that the "demand" for excess reserves has indeed undergone structural change. Thus, the study indicates that conventional approaches to commercial bank behavior and the demand for excess reserves need to be reworked.
Optimal Control for Precision Irrigation of a Large‐Scale Plantation

Field: Agricultural and Biological Sciences (Life Sciences)

Abstract Distributing water optimally is a complex problem that many farmers face yearly, especially in times of drought. In this work, we propose optimization‐based feedback control to improve crop yield and water productivity in agriculture irrigation for a plantation consisting of multiple fields. The interaction between soil, water, crop (sugarcane in this work), and the atmosphere is characterized by an agrohydrological model using the crop water productivity modeling software AquaCrop‐OS. To optimally distribute water over the fields, we propose a two‐level optimal control approach. In this approach, the seasonal irrigation planner determines the optimal allocation of water over the fields for the entire growth season to maximize the crop yield, by considering an approximation of the crop productivity function. In addition, the model predictive controller takes care of the daily regulation of the soil moisture, respecting the water distribution decided on by the seasonal planner. To reduce the computational complexity of the daily controller, a mixed‐logic dynamical model is identified based on the AquaCrop‐OS model. This dynamical model incorporates saturation dynamics explicitly to improve model quality. To further improve performance, we create an evapotranspiration model by considering the expected development of the crop over the season using remote‐sensing‐based measurements of the canopy cover. The performance of the two‐level approach is evaluated through a closed‐loop simulation in AquaCrop‐OS of a real sugarcane plantation in Mozambique. Our optimal control approach boosts water productivity by up to 30% compared to local heuristics and can respect water use constraints that arise in times of drought.
Pericyte Ultrastructural Alterations In The Gastrointestinal Adenocarcinomas Microvasculature

Field: Medicine (Health Sciences)

Abstract Pericytes are cells of mesodermal origin that intimately surround most types of blood capillaries as well as postcapillary venules and precapillary arterioles (smooth muscle cells are found in the walls of larger vessels). Although abnormalities of capillary endothelial cells have been described in diseases such as diabetes, arterial hypertension, autoimmune inflammatory myopathies and also in the paraneoplastic phenomenon, much less is known about morphology of pericytes and its implications in the microvascular structure in cancers, particularly those arising in the gastrointestinal tract. In this work we report the pericyte ultrastructural pathology in human gastrointestinal adenocarcinomas. Surgically resected specimens from areas of tumor center and periphery were obtained from thirteen patients (seven females and six males) between 44 and 76 years of age (mean 61.92 years), with a histopathological diagnosis of gastrointestinal adenocarcinoma. Immediately after resection, tissue samples were processed by routine transmission electron microscopy techniques and observed in Hitachi H-500 and H-7100 electron microscopes.
