Objective:
This research team uses complexity science to gain a deeper understanding of daily dynamics of intimate partner violence (IPV). This report describes research methods for gathering daily information about patterns of partner violence and alcohol use from couples in near-real time, and addresses recruitment and retention, adherence to study protocol, data validity, and participant safety.
Methods:
Researchers enrolled 20 heterosexual couples with violent relationships from a primary healthcare center. Every day for 8 weeks, participants telephoned an interactive voice response (IVR) system and responded to 33 survey questions assessing violence, alcohol use, and household environment. They also completed baseline and end-of-study surveys.
Results:
Of 20 enrolled couples, 15 completed the study, providing 90% adherence to daily reporting. Participants reported verbal aggression on an average of 11-13 days over 8 weeks, and physical abuse on an average of 2-4 days. Alcohol use was modest and infrequent. Women and men differed in their reports of women's physical aggression. No reports of physical violence were correlated with social desirability.
Conclusions:
We demonstrated the feasibility of enrolling and engaging both women and men in daily longitudinal research about partner violence and described advantages of IVR in daily longitudinal research.

01:20Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)
The central atom need not be NMR-active because its electrons are affected by the electron polarization of the spin-active atoms. However, spin information is transmitted less effectively than in one-bond coupling, and 2J values are usually weaker than 1J values. The energy of...

The extent of coupling depends on the C‑C bond length, the two H‑C‑C angles, any electron-withdrawing substituents, and the dihedral angle between the involved orbitals. The...

02:29Ethers from Alcohols: Alcohol Dehydration and Williamson Ether Synthesis
Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.
02:31Protection of Alcohols
Protection
It defines a protecting group as the masking agent to make the more reactive species inert to a given set of conditions. This concept is depicted via the illustration of liquid flow through different outlets in an assembly of pipes. The analogy helps to understand the role...
