Will firm's marketing efforts on owned social media payoff? A quasi-experimental analysis of tourism products

quasi-experimental designs

Chang HL, Chou YC.
GSID: OSBIYE765uUJ
HL Chang, YC Chou, DY Wu, SC Wu - Decision Support Systems, 2018 - Elsevier

… Using a quasi-experimental design and difference-in-difference estimation, we evaluate the effect of a firm's efforts on Facebook marketing campaigns after controlling time-fixed selection bias and common time-series heterogeneity. The results show that Facebook campaign …

How Much Control is Enough for Network Connectivity Preservation and Collision Avoidance?.

IEEE transactions on cybernetics

Chen Z, Fan MC, Zhang HT.
PMID: 25291811
IEEE Trans Cybern. 2015 Aug;45(8):1647-56. doi: 10.1109/TCYB.2014.2357838. Epub 2014 Sep 29.

For a multiagent system in free space, the agents are required to generate sufficiently large cohesive force for network connectivity preservation and sufficiently large repulsive force for collision avoidance. This paper gives an energy function based approach for estimating...

Role of CXC chemokine receptor type 7 in carcinogenesis and lymph node metastasis of colon cancer.

Molecular and clinical oncology

Wang HX, Tao LY, Qi KE, Zhang HY, Feng D, Wei WJ, Kong H, Chen TW, Lin QS, Chen DJ.
PMID: 26807225
Mol Clin Oncol. 2015 Nov;3(6):1229-1232. doi: 10.3892/mco.2015.643. Epub 2015 Sep 15.

Upregulated expression of the CXC chemokine receptor type 7 (CXCR7) promotes breast, lung and prostate cancer progression and metastasis. However, the role of CXCR7 in colon cancer has not been determined. We hypothesized that increased CXCR7 expression may contribute...

Adhesion of the iron-chromium oxide interface from first-principles theory.

We determine the interface energy and the work of separation of the Fe/Cr2O3 interface using first-principles density functional theory. Starting from different structures, we put forward a realistic interface model that is suitable to study the complex metal-oxide interaction....

High performance liquid chromatography (HPLC) fingerprints and primary structure identification of corn peptides by HPLC-diode array detection and HPLC-electrospray ionization tandem mass spectrometry.

Journal of food and drug analysis

Wang C, He H, Zhang JL, Li X, Ma ZL.
