Real-Time PPP Based on the Coupling Estimation of Clock Bias and Orbit Error with Broadcast Ephemeris

Sensors, 2015
Satellite orbit error and clock bias are the keys to precise point positioning (PPP). The traditional PPP algorithm requires precise satellite products based on worldwide permanent reference stations.

How Important Is Pay and What Are the Effects (Positive and Negative) of Pay for Performance?: Evaluating Claims and Evidence

Human Resource Management, EarlyView.
ABSTRACT Compensation plays a pivotal role in shaping employee behavior, motivation, and well‐being. Although extant research has explored various dimensions of compensation, questions about how important pay is to employees and concerns (on the part of employers and/or employees) about the unintended negative (in addition to intended positive ...

Reprogramming SREBP1‐dependent lipogenesis and inflammation in high‐risk breast with licochalcone A: A novel path to cancer prevention

International Journal of Cancer, EarlyView.
What's New? Endocrine drugs repurposed from treatment protocols are the primary medications available for breast cancer (BC) prevention in at‐risk women. Adverse effects, however, significantly minimize uptake and prevention impact. Here, the authors investigated licochalcone A (LicA), a non‐endocrine anti‐inflammatory agent with reported hematologic ...

Diversity, transfer potential, and transcriptional activity of virus‐carried antibiotic resistance genes in global estuaries

iMetaOmics, EarlyView.
Estuaries are vital hotspots for antibiotic resistance genes (ARGs) due to substantial antibiotic pollution. Although viruses have been proposed as key reservoirs and important disseminators of ARGs in environments, their contribution to the estuarine antibiotic resistome remains largely unknown.

The Double‐Edged Sword of Servant Leadership: Motivational Climates, Helping Behavior, and Financial Performance

Journal of Organizational Behavior, EarlyView.
ABSTRACT Research on the effects of servant leadership on firm success has yielded inconsistent results. Connecting servant leadership theory to achievement goal theory, we theorize that servant leadership exerts both beneficial and detrimental effects on firms by shaping two distinct motivational climates: mastery climate and performance climate ...
