The existing literature contains conflicting evidence regarding the relative quality of stock market volatility forecasts. This paper employs daily Indian data to examine the relative ability of various models to forecast monthly stock market volatility. The forecasting models which were selected range from naive model to relatively complex GARCH model. While it is difficult to claim superiority of any one model under all measures used to assess the accuracy of the forecast, the overall results clearly identify two competing models i.e., the RWM and GARCH (1, 1).

The experiments described in the following paper form a continuation of researches on thermal radiation by one of the present authors, the results of which have been communicated to the Royal Society from time to time since 1884. The main object of the present experiments was to push forward the inquiry as to the amount, and the relative quality, of the radiation from surfaces of various kinds in high vacuum. When a body is maintained at a high temperature the total radiation from its surface depends, other things being the same, on the temperature and on the character of the radiating surface.

PurposeThe purpose of this research objective was to analyse social reporting within MERCO Business companies both from the point of view of the quantity of information disclosed and the references about their quality. This approach constitutes a novelty with respect to previous literature on the subject.Design/methodology/approachThis paper assesses how social reporting is being carried out by the companies included in the MERCO Corporate Reputation Business Monitor, MERCO Business, during the period 2014–2016. The methodological design include the construction of a weighted index based on two unweighted indexes related to the quantity revealed and the quality detected. In addition, this study integrates intellectual capital and social responsibility approaches in order to deep into these voluntary disclosures.FindingsWhile social reporting is considerable from a quantitative point of view within MERCO Business companies, they do not reach very high levels of quality, which is good to counteract the final value of the quantity–quality index that the authors' propose.Research limitations/implicationsIn MERCO Business companies, quantity is not a proxy for quality within social reporting. In this sense, only considering both dimensions it will be possible to assess these disclosures in a more complete way.Practical implicationsThis study allows a more accurate and comparable view of social reporting than those studies that only focus on how much information is disclosed. Besides, it involves an important advance in the identification of the relative quality of social reporting, opening a new line of research that will be key to comparing this type of disclosures in a more homogeneous way. Likewise, the results can be applied in future studies in the intellectual capital field given the complementarity between both types of disclosures.Social implicationsLikewise, these results will be of interest for future actions aimed at regulating the improvement of the quality of social reporting in the hands of managers, investors and regulators.Originality/valueThe authors have tested the value of quality in social reporting using a weighted index amongst the most reputable companies in the Spanish scenario. These disclosures have been compared with and without the use of it in order to deduce its value to obtain valid conclusions about social reporting.

Summary This article is concerned with the notion of the ages of man’s life seen from the anthropo-logical perspective as a cultural paradigm. It is obvious in all cultures that anybody who has lived a long life has to pass through the stages of childhood, youth, adulthood down to old age. Although these four ages are universally acknowledged, the length of each phase, its relative quality and value are subject to cultural variation. To reconstruct the topoi used to highlight both the more attractive and the negative aspects of old age the article examines the contents of two books from the late 16th century, Stanisław Kołakowski’s Man’s Life (1584) and Jan Protasowicz’s A Mirror of the Old Man (1597). Chief among the benefits peculiar to senectitude is the respect given to the old man’s wisdom, his counsel and advice, the quality of his political leadership; accordingly the senex can function as a paragon of virtues, a holy man who blesses the young generation, a hale old man enjoying his well-earned retirement, and a pious old man preparing for death. This complimentary picture of the rewards of old age is however offset by its accumulating ills and miseries, clumsiness and decrepitude, habitual whinging and complaining, childishness, ill-health, loneliness, naivete, proneness to romantic infatuation and ridicule. All those features that are conditioned by the nature of biological rythms and processes have a permanence about them that makes them constants of the literary descriptions of old age. The culture of the Renaissance was on the whole unfavourably disposed towards senectitude, which is borne out by the two texts analyzed in this article.
