We introduce MCMCpack, an R package that contains functions to perform Bayesian inference using posterior simulation for a number of statistical models. In addition to code that can be used to fit commonly used models, MCMCpack also contains some useful utility functions, including some additional density functions and pseudo-random number generators for statistical distributions, a general purpose Metropolis sampling algorithm, and tools for visualization.

This study seeks to investigate the effect of internal marketing—treating employees as internal customers—on salesperson's engagement in customer‐oriented behaviors and resultant customers’ responses. The data were collected from dyadic interactions between salespeople and customers in banking firms in Vietnam. The results showed that internal marketing is significantly associated with salesperson's performance of adaptive selling behavior, customer‐oriented selling behavior, and relational selling behavior, which result in customer relationship continuity, purchase intention, and positive word‐of‐mouth. In addition, salesperson's customer‐oriented behaviors play partial mediating roles between internal marketing and external customer responses. The study extends the extant literature of internal marketing and offers useful managerial implications for service firms, particularly banking firms in Vietnam. The study concludes with suggestions of potential research directions for future studies.

Alzheimer's disease (AD) is the most common cause of senile dementia in later life. Whereas several neurotransmitter systems are known to be involved and depleted in AD, the cholinergic system still receives the greatest attention by far. This is particularly true with regards to pharmacotherapy research and development 2) due to the involvement of the cholinergic system in learning and memory processing.
