A Study about Methods for Bibliometric Analysis of Research: Renewable Energy
Abstract: This paper presents methods and software implementation for analyzing a field of research through the use of bibliometrics, i.e., information about published journal articles. Online publication search engines are queried, and their search results are extracted and analyzed, to help inform a researcher of the state of his or her field. Our methodology consists of three components: extraction of terms relevant to the research field, analysis of the growth in prevalence of these terms over time, and identification of interrelationships among these terms using a technique known as Latent Semantic Analysis. These methods are applicable to the analysis of any research field, but this paper presents results from a case study on the field of renewable energy.
Introduction: For researchers in a technical field, understanding the state of their area of interest is of the highest importance. Any research field is composed of many subfields and underlying technologies which are related in intricate ways. This composition, or “research landscape,” is not static. New technologies are constantly developed, while old ones become obsolete. Fields that are presently unrelated may one day become dependent on each other’s findings. An invention from decades prior may find a new application in an emerging field. Expertsin a field could already have a strong understanding of their research landscape. But it would be unreasonable to expectthem to have intimate knowledge of every aspect of theirfield. More critically, fledgling technologiesthat could one day play an importantrole are unfortunately the ones of which they aremostlikely unaware. Keep reading…
Case Study about Expansion of Industrial Logging in Central Africa
Central Africa’s dense humid forests have long been regarded as among the most pristine on Earth, but in recent decades industrial logging has become the most extensive form of land use in the region. Currently more than 600,000 km2 (30%) of forest are under logging concessions, whereas just 12% is protected.
Logging-related disturbance in the region alters ecosystem composition and biodiversity (1), opens remote areas to poaching (2), and modifies numerous functional attributes of the ecosystem (3). Laws and regulations are in place to improve forest management at national and regional scales, but limited resources are available to enforce regulations or to provide technical support (4). Here, we report on the use of over 300 Landsat satellite images, covering 4 million km2 , to track the progression of logging roads for three decades preceding 2003 (5). We document accelerating rates of logging road construction in much of the region and show that monitoring with satellite remote sensing provides a practica l approach to map changes associated with logging activities.

Case Study about Positive Reinforcement and 3-Dimensional Informetrics
We show that the composition of two information production processes (IPPs), where the items of the first IPP are the sources of the second, and where the ranks of the sources in the first IPP agree with the ranks of the sources in the second IPP, yields an IPP which is positively reinforced with respect to the first IPP. This means that the rank-frequency distribution of the composition is the composition of the rank-frequency distribution of the first IPP and an increasing function, which is explicitly calculable from the two IPPs’ distributions. From the rank-frequency distribution of the composition, we derive its size-frequency distribution in terms of the size-frequency distribution of the first IPP and of the function.
Such studies can be interesting, certainly if they are made in connection with evolution in time. However, in order to really understand information production, one needs to study two-dimensional informetrics, where one considers two objects, one called the sources and the other one called the items and where it is understood that the items are produced by the sources. Of course, here, one does not only perform two times a one-dimensional informetrics study (one for the sources and one for the items) but one studies the “higher” (more interesting) problem of the link between sources and items, i.e. which sources produce which items. One could say that such a study implies the two onedimensional informetrics studies but not vice-versa. Keep reading…
“The best part of implementing Escrow Verification Services is the confidence that I have in ensuring that the version of source code in escrow at Iron Mountain in fact can be compiled. It is a valid set of complete source code, not just a subset. And, if something happens to one of these small vendors, then we know we have a good set of code that actually operates.”

The Challenge: With such a significant investment in financial processing software, QBE the Americas needed to know their applications were protected. Fruchtman continues, “We used this software not only for financial reporting, but also for booking to the ledger for our annual financial statements. It’s really the core of business data that we have, and in insurance your data really is your most valuable asset.” QBE had their mission-critical software source code protected through an escrow agreement with Iron Mountain…
The Solution: Adding verification services to an escrow arrangement helps minimize risks. Essentially, escrow verification services ensure that authorized users will be able to quickly and effectively read, recreate, and maintain critical technology assets in the event of a deposit release. QBE the Americas selected Iron Mountain’s Deposit Compile Verification Services to provide a complete examination of the composition of escrow deposits and identify any missing components…

At its Padeswood Works, Hanson Cement formerly Castle Cement manufactures six different grades of cement, with a total production rate of around 500,000 tpa; five of the grades have the same composition and differ only in terms of fineness. Off-line laser diffraction particle size analysis convinced Castle Cement of the relative benefits of the technique compared with Blaine measurement, but analytical frequency became a limiting factor in terms of gaining greater insight into plant performance. An on-line Insitec system was installed to continuously monitor the particle size of product leaving the finish milling circuit. Learn more..
There is evidence that compensation levels are linked to firm performance as well as monitoring, in other words, the composition of the board influence compensation.
The Industry firms might pay the CEO for performance. Also, stock ownership influence compensation levels; when the five largest shareholders increase their holdings, CEO compensation levels decrease. We interpret this finding as that monitoring is important and the agency costs can be reduced by higher holdings by institutional investors. Read more…
Parachute has a high brand recall value. When we think of hair oil in general and coconut oil in particular, Parachute is the first brand which comes to our minds. Advertisements of Parachute focus on the “Pure” and “Natural” features of the oil which has made it popular in most Indian households, who have been using it for many years now. Hair-oils have undergone a number of changes in terms of composition, advertising etc ever since they were first introduced. And consumer preferences have also changed accordingly with youngsters more comfortable with the “non-sticky” oils. Yet, the Parachute bottle with its distinct blue colour does crop up somewhere in the mind space of consumers, even non-users…click here to read ahead
