Impact of gold and oil prices on the stock market in Pakistan
Full text linkPurpose: The purpose of the study is to find out the impact of gold and oil prices on the stock market.
Design/methodology/approach: This study uses the data on gold prices, stock exchange and oil prices for the period 1991–2016. This study applied descriptive statistics, augmented Dickey–Fuller test, correlation and autoregressive distributed lag test.
Findings: The data analysis results showed that gold and oil prices have a significant impact on the stock market.
Research limitations/implications: Following empirical evidence of this study, the authors recommend that investors should invest in gold because the main reason is that hike in inflation reduces the real value of money, and people seek to invest in alternative investment avenues like gold to preserve the value of their assets and earn additional returns. This suggests that investment in gold can be used as a tool to decline inflation pressure to a sustainable level. This study was restricted to use small sample data owing to the availability of data from 1991 to 2017 and could not use structural break unit root tests with two structural break and structural break cointegration approach, as these tests require high-frequency data set.
Originality/value: This study provides information to the investors who want to get the benefit of diversification by investing in gold, oil and stock market. In the current era, gold prices and oil prices are fluctuating day by day, and investors think that stock returns may or may not be affected by these fluctuations. This study is unique because it focusses on current issues and takes the current data in this research to help investment institutions or portfolio managers.

Diseño/metodología/enfoque: Este estudio utiliza los datos sobre los precios del oro, la bolsa de valores y los precios del petróleo para el período 1991-2016. Este estudio aplicó estadística descriptiva, prueba de Dickey-Fuller aumentada, correlación y prueba de retardo distribuido autorregresivo. Hallazgos: Los resultados del análisis de datos mostraron que los precios del oro y el petróleo tienen un impacto significativo en el mercado de valores. Limitaciones/implicaciones de la investigación: Siguiendo la evidencia empírica de este estudio, los autores recomiendan que los inversores inviertan en oro porque la razón principal es que el aumento de la inflación reduce el valor real del dinero y la gente busca invertir en vías de inversión alternativas como el oro para preservar el valor de sus activos y obtener rendimientos adicionales. Esto sugiere que la inversión en oro puede utilizarse como herramienta para reducir la presión inflacionaria a un nivel sostenible. Este estudio se limitó a utilizar datos de muestras pequeñas debido a la disponibilidad de datos de 1991 a 2017 y no pudo utilizar pruebas de raíz unitaria de ruptura estructural con dos enfoques de ruptura estructural y cointegración de ruptura estructural, ya que estas pruebas requieren un conjunto de datos de alta frecuencia. Originalidad/valor: Este estudio proporciona información a los inversores que desean obtener el beneficio de la diversificación invirtiendo en oro, petróleo y mercado de valores. En la era actual, los precios del oro y del petróleo fluctúan día a día, y los inversores piensan que los rendimientos de las acciones pueden verse afectados o no por estas fluctuaciones. Este estudio es único porque se centra en temas actuales y toma los datos actuales de esta investigación para ayudar a las instituciones de inversión o administradores de cartera
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Biopsychosocial determinant of quality of life of older adults in Pakistan and Canada
Full text linkBackground: The rapidly rising average age of the older adults has brought various global healthcare challenges. A core challenge is how to enhance their quality of life (QoL). Objective: The objective of the current study was to test the significance of biopsychosocial determinants of quality of life of older adults in Pakistan and Canada. Methodology: A cross-sectional survey was carried out on a conveniently approached purposive sample of 1,005 older adults (Pakistani = 557 and Canadian = 448) of age range between 60 years and 80 years. The data were collected via demographic datasheet, World Health Organization Quality of Life Brief Scale, Health and Lifestyle Questionnaire, General Self-Efficacy Scale, Rosenberg Self-Esteem Scale, and Berlin Social Support Scale. Results: The results of hierarchical regression analysis showed that biopsychosocial factors (viz., health and lifestyle, chronic illness, self-efficacy, self-esteem, and social support) significantly predicted (R2 =.27, and.68) quality of life of older adults in Pakistan and Canada, respectively, after controlling the demographic variables. Significant differences were found between Pakistani and Canadian older adults on biopsychosocial factors: Canadian older adults scored significantly higher on health and lifestyle, self-efficacy, and quality of life, and older adults in Pakistan scored significantly higher on self-esteem and social support. Conclusion: A significant amount of better QoL of older adults can be achieved through enhancing the biopsychosocial correlates of their QoL, both in Pakistan and Canada.</p
