Investigating the intertwining impact of wholesale access pricing and the commitment to net neutrality principle on European next-generation access networks private investment plans: An options-game application for capturing market players' competitive interactions

Whilst the deployment of next generation access networks (NGANs) is undoubtedly beneficial to the economy, new legal developments in the United States (US) regarding the issue of net neutrality (NN) pose a new challenge not only to policy makers but to telecommunication providers as well, that could justify a fresh approach when assessing NGANs investments. In particular, the Federal Communications Commission (FCC) subverted extant NN rules in the US and if the European Union (EU) decides to follow a similar deregulatory path in the future it could change the way telecommunications providers on both sides of the Atlantic lay down their optical-fibre network infrastructure investment plans. For instance, if traffic prioritization is allowed then diversification of revenue sources can be achieved by charging customers for privileged data delivery to their premises. Currently, NGANs roll-out throughout EU is an ongoing process in a setting whereby access regulation in the form of network element unbundling is already imposed. As a result, these legal developments form a new context within which it makes sense to assess the role of NGANs wholesale access pricing in tandem with the degree of commitment to NN rules so as to i) determine their combinatorial impact on private telecommunications operators' financial figures and ii) capture their competitive interactions. Towards this end, an important aspect of particular value to market players (i.e. incumbents and competitive providers – CPs), and policy makers (i.e. National Regulatory Authorities – NRAs) that this article aims to examine is how to employ the option-game (OG) analysis, that reflects the intersection of game theory (GT) and real options (ROs), to model the competitive interactions between participants in a particular competition game set-up by means of deriving possible Nash-equilibrium (NE) outcomes within a regulatory setting part of which is the commitment or non-commitment to the NN principle. This, hybrid, evaluation tool is applied on top of a conventional discounted cash flow (DCF) techno-economic analysis assessment of an NGAN investment opportunity.

Glycemic control among patients with type 2 diabetes who initiate basal insulin: a retrospective cohort study

Objective:

To examine changes in glycemic control for patients with type 2 diabetes mellitus (T2DM) after initiation of basal insulin and factors associated with improved glycemic control.

Methods:

An analysis of retrospective medical records of patients with T2DM was examined using Humedica’s electronic medical records database (January 2007–August 2012). Patients with T2DM, initiating basal insulin, age ≥21 years, with a recorded HbA1c test in both the 1 year prior and the 2 years post-initiation were included. A multivariate regression examined factors associated with changes in glycemic control. Logistic regressions examined factors associated with improvements or worsening of glycemic control, compared to relatively unchanged glycemic control.

Results:

Many (14,457) individuals met the inclusion–exclusion criteria. Multivariate analyses revealed that older age (p?p?p?=?0.0138), and higher household income (p?=?0.0065) were associated with improved glycemic control. Patients diagnosed with comorbid peripheral vascular disease (p?=?0.0072), cancer (p?=?0.0019), obesity (p?=?0.0002), moderate (p?=?0.0103), and severe chronic kidney disease (p?p?=?0.0075) in the pre-period were found to have significantly improved glycemic control in the post-period. Use of prandial insulin (p?=?0.0087), pre-mix insulin (p?=?0.0003) in the pre-period, a higher pre-period HbA1c score (p?p?Limitations:

Analyses rely on electronic medical records which cannot capture patient healthcare utilization occurring outside of the data capture system. Analyses do not control for insulin dosage or type of basal insulin prescribed.

Conclusions:

Among patients with T2DM treated with basal insulin, a number of factors may influence glycemic outcomes. These findings suggest a role for a more personalized approach to the treatment of patients with T2DM.

The effect of negative online customer reviews on brand equity and purchase intention of consumer electronics in South Africa

This study investigated the effect that negative online customer reviews have on brand equity and purchase intention. This research examined the influence of negative electronic word of mouth (eWOM) on brand equity, as influenced by customer review quality, product involvement and source credibility. A 3 (high quality review versus low quality review versus no review) × 2 (high product involvement versus low product involvement) factorial experiment with 236 respondents was conducted. The results revealed that the presence of negative eWOM has a significant detrimental effect on brand equity and purchase intention. Furthermore, the effect of negative online customer reviews is more detrimental to the brand equity of a high involvement product than a low involvement product. The results also revealed that high quality reviews are more influential than low quality reviews with respect to brand equity, and the difference between the levels of eWOM source credibility has no significant effect on brand equity.
