Creswell, J. W. (2014). Research Design: Qualitative, Quantitative and Mixed Methods Approaches (4th ed.). Thousand Oaks, CA: Sage
The book Research Design: Qualitative, Quantitative and Mixed Methods Approaches by Creswell (2014) covers three approaches-qualitative, quantitative and mixed methods. This educational book is informative and illustrative and is equally beneficial for students, teachers and researchers. Readers should have basic knowledge of research for better understanding of this book. There are two parts of the book. Part 1 (chapter 1-4) consists of steps for developing research proposal and part II (chapter 5-10) explains how to develop a research proposal or write a research report. A summary is given at the end of every chapter that helps the reader to recapitulate the ideas. Moreover, writing exercises and suggested readings at the end of every chapter are useful for the readers. Chapter 1 opens with-definition of research approaches and the author gives his opinion that selection of a research approach is based on the nature of the research problem, researchers' experience and the audience of the study. The author defines qualitative, quantitative and mixed methods research. A distinction is made between quantitative and qualitative research approaches. The author believes that interest in qualitative research increased in the latter half of the 20th century. The worldviews, Fraenkel, Wallen and Hyun (2012) and Onwuegbuzie and Leech (2005) call them paradigms, have been explained. Sometimes, the use of language becomes too philosophical and technical. This is probably because the author had to explain some technical terms.

Conducting a well-established research requires deep knowledge about the research designs. Doing research can be likened to jumping into the sea which may transform into a huge ocean if the researcher is not experienced. As a PhD candidate and a novice researcher, I believe that the book "Research Design: Qualitative, Quantitative and Mixed Methods Approaches" by J.W. Creswell is a true reference guide for novice researchers since it is the most comprehensive and informative source with its reader-friendly structure.

An adaptive intervention is a set of diagnostic, preventive, therapeutic, or engagement strategies that are used in stages, and the selection of the intervention at each stage is based on defined decision rules. At the beginning of each stage in care, treatment may be changed by the clinician to suit the needs of the patient. Typical adaptations include intensifying an ongoing treatment or adding or switching to another treatment. These decisions are made in response to changes in the patient’s status, such as a patient’s early response to, or engagement with, a prior treatment. The patient experiences an adaptive intervention as a sequence of personalized treatments.

Conducting Research That Addresses Public Health Issues Worldwide
Systematic and rigorous inquiry allows us to discover the fundamental mechanisms and causes of disease and disparities. At our Office of Research ( research@BSPH), we translate that knowledge to develop, evaluate, and disseminate treatment and prevention strategies and inform public health practice. Research along this entire spectrum represents a fundamental mission of the Johns Hopkins Bloomberg School of Public Health.
From laboratories at Baltimore’s Wolfe Street building, to Bangladesh maternity wards in densely packed neighborhoods, to field studies in rural Botswana, Bloomberg School faculty lead research that directly addresses the most critical public health issues worldwide. Research spans from molecules to societies and relies on methodologies as diverse as bench science and epidemiology. That research is translated into impact, from discovering ways to eliminate malaria, increase healthy behavior, reduce the toll of chronic disease, improve the health of mothers and infants, or change the biology of aging.

Generosity helps our community think outside the traditional boundaries of public health, working across disciplines and industries, to translate research into innovative health interventions and practices
Introducing the research@BSPH Ecosystem
The research@BSPH ecosystem aims to foster an interdependent sense of community among faculty researchers, their research teams, administration, and staff that leverages knowledge and develops shared responses to challenges. The ultimate goal is to work collectively to reduce administrative and bureaucratic barriers related to conducting experiments, recruiting participants, analyzing data, hiring staff, and more, so that faculty can focus on their core academic pursuits.
Research at the Bloomberg School is a team sport.
In order to provide extensive guidance, infrastructure, and support in pursuit of its research mission, research@BSPH employs three core areas: strategy and development, implementation and impact, and integrity and oversight. Our exceptional research teams comprised of faculty, postdoctoral fellows, students, and committed staff are united in our collaborative, collegial, and entrepreneurial approach to problem solving. T he Bloomberg School ensures that our research is accomplished according to the highest ethical standards and complies with all regulatory requirements. In addition to our institutional review board (IRB) which provides oversight for human subjects research, basic science studies employee techniques to ensure the reproducibility of research.

Electrocatalytic CO 2 reduction to CH 4 remains challenging due to multi-electron transfer and intermediates adsorption. Herein, we synthesized electrocatalysts by growing Ni-Cu alloy structure on nitrogen-doped carbon nanotubes (Ni x Cu y -NCNT) for electrocatalytic CO 2 reduction reaction (CO 2 RR) via hydrothermal method followed by pyrolysis. The optimized Ni 1 Cu 1 -NCNT demonstrated a superior CO 2 RR performance, achieving 99.7% \(\text{FE}_{\text{CH}_{4}}\) (FE = Faradaic efficiency) and 11.54 mA • cm −2 current density at −1.2 V vs. reversible hydrogen electrode (RHE), which outperformed single metal counterparts. Its outstanding performance was due to the electrons transferred from Cu to Ni and Ni-Cu alloy shifted the d-band center toward the Fermi level, which was more conducive to the intermediate formation. In situ electrochemical attenuated total reflection (EC-ATR) and density functional theory (DFT) calculations revealed the appearance of *CHO intermediate and the pathway during the CO 2 RR process. The design of the bimetallic electrocatalyst in this study provides a new perspective for the highly selective reduction of CO 2 .
