Paying It Forward: The Role of Senior Black Faculty in Preparing Junior Faculty and Black Doctoral Students for Career Success

Abstract:Senior Black faculty make a valuable contribution to the professorate by serving intentionally and vicariously as mentors to junior Black faculty and doctoral students. The authors of this research discuss the outcomes of a project consisting of two panel seminars that were provided to junior Black faculty and doctoral students at a Research I urban university. Topics covered included department politics, the publication process, developing a research agenda, submission of the tenure “package,” and the review process. This article concludes with implications for Black doctoral student retention and increasing the number of Black faculty in higher education who attain promotion and tenure.
TRABAJO DE GRADO MÉTODOS ROBUSTOS DE DECONVOLUCIÓN PARA LA ESTIMACIÓN DE PARÁMETROS DESCRIPTORES DE PERFUSIÓN CEREBRAL POR RESONANCIA MAGNÉTICA* (*) Título original: “Deconvolution Robustness for Local Perfusion Parameters Estimation in Magnetic Resonance Imaging (MRI)”

In clinical practice, it is frequently desired to estimate the cerebral blood flow since it is a valuable indicator of the patient’s tissular viability. The purpose of this study was to determine the robustness of two algorithms in blood flow estimation using MR imaging. To identify this perfusion parameter, both algorithms use the same physiological model but they differ in the mathematical procedure. The required mathematical operator is called deconvolution and one of the algorithms uses a singular value decomposition (SVD) method, whereas the other one applies an Auto-Regressive Moving Average (ARMA) model. The performances of both deconvolution methods are exposed here, under different noisy environments, in cerebral blood flow estimation.
The Effect of CEO Overconfidence on Product Market Performance

This paper provides empirical evidence that CEO overconfidence can play a role on firm product market performance. Some studies provide empirical evidence that irrational managers may engage in actions that can be detrimental to firm value while others suggest that an overconfident manager can increase firm value. This work analyzes the relationship between CEO overconfidence and within-industry sales performance of the firm, and find that higher overconfidence levels are associated with better product market performance.
cacy and safety of adrenocorticotropic hormone treatment in glomerular diseases : a systematic review and meta-analysis

Background: There is growing evidence that adrenocorticotropic hormone (ACTH)may be effective in treating various forms of glomerular diseases. However, the efficacy of treatment and frequency of adverse effects associated with the use of ACTH in glomerular diseases are unknown. A systematic review and meta-analysis of the literature was performed. Methods: A literature search was performed using Medline, Embase, Google Scholar and the Cochrane Database of Systematic Reviews from inception through 18 July 2015. Studies assessing the efficacy and safety of ACTH treatment in adults with glomerular diseases were included. Results: Of the 343 identified citations, 18 evaluated the drug efficacy and 12 evaluated the adverse effects. Themost common glomerular diseases were membranous nephropathy (MN), primary focal segmental glomerulosclerosis (FSGS) and minimal change disease (MCD). The overall rate of complete remission inMNwas 80%at 0–6months, 69%at >6–12months, 90%at >12–24 months and 95% beyond 24 months of follow-up. Fifty percent of primary FSGS and MCD patients treated with ACTH were in remission at 6 months, but the relapse rate was high after ACTH discontinuation (17%). Evidence of ACTH efficacy for other glomerular diseaseswas scarce. Edemawas themost commonly reported adverse effect {incidence rate [IR] 0.10 [95% confidence interval (CI) 0.04–0.18]} followed by insomnia [IR 0.08 (95% CI 0.03–0.15)]. The dropout rate due to adverse events was 7%,mostly due to edema and weight gain. Conclusions: ACTH is awell-tolerated therapy and ismost promisingwhen treating patientswithMN. Theremay be a potential role for ACTH in patients with MCD and FSGS, but data are lacking.
Ameliorative Effect of Cimetidine and Silymarin on Acute Acetaminophen-induced Hepatotoxicity in Adult Albino Rats: An Experimental Comparative Study

Acetaminophen is an analgesic and antipyretic drug, its overdose cause hepatotoxicity. The current antidote for acetaminophen hepatotoxicity is N-acetyl cysteine (NAC); however, NAC has been resulted in severe side effects as seizures, intracranial hypertension and cerebral edema. This study aimed to assess and compare the ameliorative effects of cimetidine and silymarin against acute acetaminophen–induced hepatotoxicity. Fifty four adult albino rats were divided into nine groups: negative control; solvent control; silymarin control; cimetidine control; cimetidine and silymarin control; acetaminophen group; acetaminophen and silymarin group; acetaminophen and cimetidine group; acetaminophen, cimetidine and silymarin group. A single dose of: acetaminophen (800 mg/kg, orally); silymarin (150mg/kg, orally) and cimetidine (150 mg/kg, intraperitoneally) were given according to study regimen. Liver histopathology, biochemical analysis of liver aminotransferases (AST & ALT) and hepatic tissue levels of oxidative stress index (MDA) and antioxidant (GSH) were assessed. Treatment with cimetidine alone gave better biochemical results as compared to treatment with silymarin alone. However combined treatment with cimetidine and silymarin showed better ameliorative effects than either of them given alone, evidenced by better improvement in histopathological examination and biochemical results as compared to other tested groups, and these results were non-significant as compared to controls. In conclusion treatment with silymarin and cimetidine in-combination for acute acetaminophen–induced hepatotoxicity showed better improvement probably due to synergistic hepatoprotective effects.
Floodplain Styles of the Lower Pánuco Basin, Mexico

Floodplains exhibit a variety of styles because of the dominance of specific fluvial processes. This study examines the spatial diversity of floodplain styles in the lower Pánuco basin, a large river system that drains east-central Mexico and empties into the Gulf of Mexico at Tampico, Tamaulipas. Changes in mean stream power (W m-2) and surficial floodplain environments are considered for distinct valley segments. Valley width and channel width increase downstream, although lithologic controls result in the floodplain width being highly variable. Mean stream power decreases from 375 (W m-2) in the Río Moctezuma valley in the upper portions of the coastal plain, to 14 (W m-2) in the lower reaches of the Río Pánuco. Channel deposits are more significant to floodplain construction in the upper coastal plain. In the lower Moctezuma the valley width abruptly increases and floodplain gradient decreases, which results in a more diverse suite of floodplain deposits. In the lower Pánuco valley overbank processes characterize the floodplain, which is manifest as wide natural levees and large backswamp basins. Resumen Las llanuras de inundación presentan una variedad de estilos de acuerdo con los específicos procesos fluviales. Este estudio examina la diversidad espacial de los estilos de la llanura de inundación dentro la cuenca baja del río Pánuco, un sistema fluvial grande de drenaje del centro-este de México que sale al Golfo de México cerca Tampico, Tamaulipas. Cambios en el poder medio de la corriente (W -2) y la superficie de la llanura de inundación son analizados en distintos sectores del valle. La anchura del valle y del canal del río aumentan río abajo, aunque los controles litológicos resultan en una anchura muy variable. El poder medio de la corriente se disminuye de 375 (W -2) en el valle del río Moctezuma, río arriba, a 14 (W -2) en los tramos bajos del río Pánuco. Los depósitos del canal son más importantes en la construcción de la llanura de inundación en la planicie costanera superior. En el río Moctezuma abajo la anchura del valle se amplia abruptamente y el declive de la llanura se disminuye, lo que trae como resultado una serie de depósitos aun más diversa. En el río Pánuco abajo, la llanura de inundación se caracteriza por los procesos "overbank", (inundación), que se manifiestan como anchos diques y cuencas pantanosas.
ThehistonesH 2 A / H 2 BandH 3 / H 4 are imported into the yeast nucleus by different mechanisms

Proteins are imported from the cytoplasm into the nucleus by importin -related transport receptors. The yeast Saccharomyces cerevisiae contains ten of these importins, but only two of them are essential. After transfer through the nuclear pore, importins release their cargo upon binding to the RanGTPase, the key regulator of nuclear transport. We investigated the import of the core histones in yeast and found that four importins are involved. The essential Pse1p and the nonessential importins Kap114p, Kap104p, and Yrb4p/Kap123p specifically bind to histones H2A and H2B. Release of H2 histones from importins requires Ran-GTP and DNA simultaneously suggesting a function of the importins in intranuclear targeting. H3 and H4 associate mainly with Pse1p and the dissociation requires Ran but not DNA, which points to a different import mechanism. Import of green fluorescent protein fusions to H2A and H2B requires primarily Pse1p and Kap114p, whereas Yrb4p plays an auxiliary role. Pse1p is predominantly necessary for nuclear uptake of H3 and H4, while Kap104p and Yrb4p also support import. We conclude from our in vivo and in vitro experiments that import of the essential histones is mediated mainly by the essential importin Pse1p, while the non-essential Kap114p functions in a parallel import pathway for H2A and H2B.

Grain Growth in Large-Scale Molecular Dynamics Simulation: Linkage between Atomic Configuration and von Neumann-Mullins Relation

It is essential to control the microstructure of metals and alloys precisely during the production process since it affects physical and mechanical properties. Many practical metals and alloys undergo solidification and subsequent grain growth during their production.1) Therefore, it is important to understand a series of fundamental physics ranging from nucleation and solidification to grain growth comprehensively. Although a lot of efforts have been made over years to understand fundamental aspects of microstructure evolution,2) however, it is still challenging to control microstructures with a high degree of accuracy. One of the difficulties is to observe the evolution of threedimensional microstructure as it is during the production process. Although recent new methodologies such as synchrotron X-ray microtomography3) and serial sectioning technique4) achieve three-dimensional morphology of microstructure experimentally, most of observation and Grain Growth in Large-Scale Molecular Dynamics Simulation: Linkage between Atomic Configuration and von Neumann-Mullins Relation
Working Paper CAUSAL LINKAGES BETWEEN GOVERNMENT REVENUE AND SPENDING : EVIDENCE FROM GHANA

This study examines the causal links between revenues and expenditures of Ghana over the period 1983 to 2007 within the framework of Engle-Granger bivariate cointegration and error correction model. The bivariate cointegration results support the hypothesis that revenues and expenditures are cointegrated. Within the error correction approach, the paper finds evidence in support of tax-spend hypothesis in short run, while the spend-tax hypothesis is supported in long run. Policies intended to curtail Ghana’s recurring budget deficit problems must focus on adjusting revenues in the short run while a re-ordering of the intertemporal relationship between revenues and expenditures in a manner consistent with the economy’s revenue mobilization potential is absolutely crucial.
The Examining of Job Satisfaction Level of Koran Teachers In Terms of Some Variables

The aim of this study is to analyze the job satisfaction level of Koran teachers. The relationships between the job satisfaction level of Koran teachers and some demographic status (gender, age and educational level) were examined. For this purpose, the Koran teachers on the sample of 243 questionnaires were selected. Statistical operations on the data obtained were analyzed via SPSS program. At the conclusion of the study, it was found that gender is the ineffective factor; educational level and age are the effective factors for job satisfaction of Koran teachers.
Changes in dimethyl sulfide oceanic distribution due to climate change

Dimethyl sulfide (DMS) is one of the major precursors for aerosols and cloud condensation nuclei in the marine boundary layer over much of the remote ocean. Here we report on coupled climate simulations with a state‐of‐the‐art global ocean biogeochemical model for DMS distribution and fluxes using present‐day and future atmospheric CO2 concentrations. We find changes in zonal averaged DMS flux to the atmosphere of over 150% in the Southern Ocean. This is due to concurrent sea ice changes and ocean ecosystem composition shifts caused by changes in temperature, mixing, nutrient, and light regimes. The largest changes occur in a region already sensitive to climate change, so any resultant local CLAW/Gaia feedback of DMS on clouds, and thus radiative forcing, will be particularly important. A comparison of these results to prior studies shows that increasing model complexity is associated with reduced DMS emissions at the equator and increased emissions at high latitudes.
Application of the theories that explain the causes of civil conflicts in Zimbabwean conflicts

There are several theories which tend to explain the causes of civil conflicts. These theories have identified certain elements or conditions which make civil conflicts feasible. Zimbabwe has experienced conflicts. Each time such conflicts have occurred, no one has been well prepared to handle them or prevent them. This paper attempts to examine and analyse various theories relating to the causes of civil conflicts and identifies elements in the theories which are critical to the causes of a civil conflict. The purpose is to identify natural and man-made elements that would make civil conflicts inevitable. By identifying such elements, the country can adequately prepare itself in preventing civil conflicts before they occur. The presence of abundant natural resources in Zimbabwe is seen as endowment and a blessing. Theory, however, predicts it as a source of its problems. By knowing the risks posed by such primary commodity export, measures can be taken to minimise the opportunities of civil conflicts through equitable distribution of their benefits or other measures as seen fit.
EAI Endorsed Transactions on Security and Safety

Broadcasting is a communication mechanism utilized in VANET architecture that facilitates in disseminated of public information to help reduce traffic jams/congestions. The authentic and genuine nature of public information is required to be maintained to avoid broadcasting of false information causing mass panic and hysteria. Therefore, it is of utmost importance to secure the broadcasting information so that an intruder is unable to alter any information without compromising public nature of the information. In this paper, we have proposed a secure broadcasting architecture consisting of different layers stacked together in different formation according to operating modes. A real-time simulation model is developed in Python, while simulations are run on a supercomputer for the purpose of gathering results for highway environments. We compare the results of the proposed secure highway architecture with unsecure architecture. Overall, the results show delayed propagation time due to the availability of multiple information packets as well as prioritization of these information packets. However, there was no significant difference in retransmission of different information packets when compared with either different broadcasting probability or unsecure highway scenario, which indicates an effective as well as efficient, secure broadcasting architecture.

Hyperglycemia downregulates Connexin 36 in pancreatic islets via the upregulation of ICER-1 / ICER-1 g

Channels formed by the gap junction protein Connexin36 (CX36) contribute to the proper control of insulin secretion. We previously demonstrated that chronic exposure to glucose decreases Cx36 levels in insulin-secreting cells in vitro. Here, we investigated whether hyperglycemia also regulates Cx36 in vivo. Using a model of continuous glucose infusion in adult rats, we showed that prolonged (24–48 h) hyperglycemia reduced the Cx36 gene Gjd2 mRNA levels in pancreatic islets. Accordingly, prolonged exposure to high glucose concentrations also reduced the expression and function of Cx36 in the rat insulin-producing INS-1E cell line. The glucose effect was blocked after inhibition of the cAMP/PKA pathway and was associated with an overexpression of the inducible cAMP early repressor ICER1/ICER-1g, which binds to a functional cAMP-response element in the promoter of the Cx36 gene Gjd2. The involvement of this repressor was further demonstrated using an antisense strategy of ICER-1 inhibition, which prevented glucose-induced downregulation of Cx36. The data indicate that chronic exposure to glucose alters the in vivo expression of Cx36 by the insulin-producing b-cells through ICER-1/ICER-1g overexpression. This mechanism may contribute to the reduced glucose sensitivity and altered insulin secretion, which contribute to the pathophysiology of diabetes. Key Words
Leadership ’ s Role in Employee Retention

Using a framework of social exchange theory (SET) to demonstrate the outcome of a leadership-employee centered model, this study demonstrated the vital role that the relationship between employee and leaders play in influencing an employee’s future career decisions. Leader-member exchange (LMX) was proposed to have a mediating effect on this model. Survey research of 402 fulltime employees recruited through Amazon MTurk from a diverse selection of industries was used to explore these relationships. The survey instrument included measures of person-job fit, turnover intention and employee work engagement factors such as vigor, dedication, and absorption. This study contributes to literature regarding P-J fit, LMX, and employee work engagement empirically tested within a single framework. Results confirm that person-job fit has an inverse relationship to turnover intention and mediated through LMX and employee work engagement.
Enforcing Local Non-Zero Constraints in PDEs and Applications to Hybrid Imaging Problems

We study the boundary control of solutions of the Helmholtz and Maxwell equations to enforce local non-zero constraints. These constraints may represent the local absence of nodal or critical points, or that certain functionals depending on the solutions of the PDE do not vanish locally inside the domain. Suitable boundary conditions are classically determined by using complex geometric optics solutions. This work focuses on an alternative approach to this issue based on the use of multiple frequencies. Simple boundary conditions and a finite number of frequencies are explicitly constructed independently of the coefficients of the PDE so that the corresponding solutions satisfy the required constraints. This theory finds applications in several hybrid imaging modalities: some examples are discussed.
Oceanic origin of the interannual and interdecadal variability of the summertime western Pacific subtropical high

A recent study found that the western Pacific Subtropical High (WPSH) exhibits both quasi‐biennial (2–3 years) and low‐frequency (3–5 years) oscillations. While the quasi‐biennial oscillation is prominent in 1990s, the 3–5 year oscillation is dominant in 1980s. The two oscillations were attributed to the atmospheric response to the remote forcing of sea surface temperature (SST) in the maritime continent and equatorial central‐eastern Pacific, respectively. The present study confirms this hypothesis. When forced by observational SST, the ensemble simulation with the NCAR CAM2 model reasonably reproduces the main characteristics of quasi‐biennial oscillation and low‐frequency oscillations of the WPSH. The quasi‐biennial oscillation is associated with anomalous overturning circulation characterized by enhanced convection over the maritime continent and subsidence over the western North Pacific. The low‐frequency oscillation is mainly modulated by remote forcing of SSTA in the equatorial central‐eastern Pacific. The model reasonably reproduces the interdecadal transition of the WPSH from low‐frequency oscillation in 1980s to quasi‐biennial oscillation in 1990s, suggesting that the SST forcing is an essential factor to modulate the interdecadal variation of the WPSH.
Geoids in general relativity: geoid quasilocal frames

We develop, in the context of general relativity, the notion of a geoid—a surface of constant ‘gravitational potential’. In particular, we show how this idea naturally emerges as a specific choice of a previously proposed, more general and operationally useful construction called a quasilocal frame—that is, a choice of a two-parameter family of timelike worldlines comprising the worldtube boundary of the history of a finite spatial volume. We study the geometric properties of these geoid quasilocal frames, and construct solutions for them in some simple spacetimes. We then compare these results—focusing on the computationally tractable scenario of a non-rotating body with a quadrupole perturbation—against their counterparts in Newtonian gravity (the setting for current applications of the geoid), and we compute general-relativistic corrections to some measurable geometric quantities.
The evaluation of burnout levels of sports sciences faculty students

The aim of this research is to evaluate the burnout levels of sports sciences faculty students in terms of some other variables. 46 Female (Age, M: 20.88±1.86) and 107 male (Age, M: 22.15±2.15) in total 153 students participated in this research. Maslach Burnout Inventory – Student Form (MBI–SF) was used for data collection. Descriptive statistics and Multivariate Analysis of Variance (MANOVA) analyses were used to analyze the data. After the data were analyzed in terms of gender, it was found that that there was a significant difference between the sub-scales of the burnout scale, depersonalization and exhaustion (p 0.05). In terms of the grade of the students, there was a statistically significant difference only on the depersonalization sub-scale of the burnout scale (p 0.05) was identified. There was a statistically significant difference only on the sub-scale of depersonalization in terms of the department of the students (p 0.05). Consequently, it appears that the burnout levels of sport sciences faculty students might change in terms of gender, class levels and within the department of education. Key words: Sports sciences, burnout, students, athletes, gender.
