Polarized and Unpolarized Lepton Pair Forward-backward Asymmetries in B‾→K‾0∗(1430)ℓ+ℓ−\overline{B}\rightarrow \overline{K}_{0}^{*}(1430) \ell^+\ell^- and B‾→K‾ℓ+ℓ−\overline{B}\rightarrow \overline{K} \ell^+\ell^- Decays in Two Higgs Doublet Model

In this paper we shall focus on the effects of concrete models such as SM and Model III of 2HDM on the polarized and unpolarized forward-backward asymmetries of $\overline{B}\rightarrow \overline{K}_0^{*}(1430) \ell^+\ell^-$ and $\overline{B}\rightarrow \overline{K} \ell^+\ell^-$ decays. The obtained results of these decay modes are compared to each other. Also, we obtain the minimum required number of events for detecting each asymmetry and compare them with the number of produced $B\bar{B}$ pairs at the LHC or supposed to be produced at the Super-LHC. At the end, we conclude that the study of these asymmetries for $\overline{B}\rightarrow \overline{K}_0^*(1430) \ell^+\ell^-$ and $\overline{B}\rightarrow \overline{K} \ell^+\ell^-$ processes are very effective tools for establishing new physics in the future B-physics experiments

Strength of drilling fluid filter cakes

Wellbore strengthening techniques are commonly used to prevent drilling fluid losses. Current methods generally require that particles are added to the drilling fluid to hinder fracture propagation, which creates practical difficulties as the particles are often relatively large. An alternative approach is the idea of using the filter cake that forms against the wellbore rock to create a robust seal, the efficacy of which will depend on cake strength. However, little is currently understood about filter cake strength and how it is impacted by typical particulates in the drilling fluid. In this work, the strength of drilling fluid filter cakes is assessed. Furthermore, filter cake properties such as porosity and thickness that are altered by constituent particles and that affect cake strength are explored. The cake strength was measured using the hole punch test and particle properties such as particle concentration, size distribution and shape were evaluated. Representative water-based and oil-based drilling fluids were analysed to establish benchmark results, which were based on the rheological and filtration behaviours as well as filter cake properties. These results produced similar trends to those of model water-based drilling fluids composed of typical drilling fluid components, such as an increase in cake strength and a decrease in cake porosity as the barite volume fraction in the fluid increased. For these model fluids, the cake strength also increased as the particle size and cake porosity decreased whilst calcium carbonate cakes were stronger than the barite equivalents. Cake strength may have been influenced by interparticle contact surface area, which was affected by cake porosity and thickness. The relationships between particle size, pore distributions and thickness were better understood by visualising the internal structure of filter cakes, using images captured via X-ray computed tomography. The images showed that the size of the pores decreased as the particle size decreased, the cakes had a more porous bottom layer than top and the porosity decreased with filtration time. Discrete element method simulations were compared with experimental results, and relationships between cake strength and the interparticle contact surface area, determined using cake porosity and particle size, were found

A comparative study in money attitude among university students: a gendered view

The paper aims to examine gender differences in money attitude among college students. Using the stratified sampling method, 2,340 college students from six public and five private colleges were studied. The findings indicate gender differences for different dimensions of money attitude, in which males were attached to money as a power/prestige tool while experiencing anxiety and having a retentive attitude toward money. Meanwhile female students were conservatively minded about money, as well as being attached to money for self-gratification purposes

Gender differences in financial well-being among college students

Financial satisfaction and its impact on the quality of life have received considerable attention in recent decades. A large number of studies have attempted to identify the dimensions of financial well-being and financial behavior among various groups in relation to the development of personal financial well-being. The majority of studies on personal financial satisfaction and financial behavior among adolescents reveal notable sex differences. There is evidence that men and women's perceptions differ and that they are not necessarily only influenced by economic factors, but also by social and psychological issues. To identify gender differences in financial well-being, this study focuses on the perceived financial well-being of Malaysian college students. This study was carried out under (IRPA) funding. Data were collected from students in public and private Malaysian universities. The multi stage stratified random sampling technique was used. A total of 11 universities were randomly selected for the study and 350 questionnaires were distributed to students through the student affairs section of the respective university. Data were collected using self-administered questionnaires. Financial well-being was measured by a six-item scale. The students were asked to rate those six items on a scale of one (not satisfied at all) to nine (very satisfied). The items statements include the amount of saving, financial situation, ability to purchase, saving for emergency expenses, skill to manage money, and ability to spend. The results revealed that there were significant gender differences among Malaysian college students concerning financial matters. The results indicate that Malaysian female students have a significantly higher level of financial satisfaction compared to male students. Female students have a lower level of financial knowledge and late age financial socialization compared to male students. The results showed that primary socialization agents were the strongest predictor of financial well-being among male students while financial problems were the strongest predictor among female students. Mediation analysis confirmed the mediation effect of financial problems in the association between predictors and financial well-being

Compliance with IS-Security-Policies: A Socio-Material Perspective Towards Security

In the face of ever-growing IS-security breaches and their substantial impacts on organizations and societies, the necessity of enhancing organizational IS-security becomes paramount. Meanwhile, the employees’ compliance with organizational IS-security policies (ISSP) is known to be critical for ensuring security. However, the extant knowledge about ISSP-compliance has remained scattered and inconclusive, and the social aspects of compliance are mostly underexplored despite their importance and impact. Moreover, there is a need for more studies that bridge the gap between the design side and the behavioral sides of IS-security; such a gap has created both conceptual and practical shortfalls within the literature. In this paper, we address these gaps by first introducing an enhanced unified framework of ISSP-compliance and, second, by theorizing a model where we propose that transparency of use enacts four distinct social practices, which, in turn, increase the employees’ compliance with ISSP. Future avenues of research are also suggested

A Data Envelopment Analysis (DEA)-Based Model for Power Interruption Cost Estimation for Industrial Companies

In this paper, a new model based on Data Envelopment Analysis (DEA) and Inverse Data Envelopment Analysis (IDEA) is presented for estimating the effect of electricity on the output of industrial companies. To this end, the effect of electricity deviation, which serves as one input that can influence a manufacturing company's final product, is evaluated. Intuitively, it is known that a direct relationship exists between electricity consumption and the output of the manufacturing company. However, finding a function that accurately represents this relationship is not easy. To check the applicability of the proposed method, it is tested on data from eight major vehicle manufacturing companies. In this model, labor hours, electrical energy consumption, and the value of raw materials are used as inputs, and the sales value is used as the proxy for the output of the company. These input and output data are used to find the efficiency of each company. Then, by changing the electricity consumption level, the output changes are derived. To calculate the outage cost, the deviation of the output is divided by the deviation of the electricity consumption, and the outage cost is estimated.Comment: IEEE ISGT 201
