Seismic Hazard Estimation

<p class="Testoformula">A homogenous database of magnitude observations is a basic requirement for seismic hazard estimation and other seismic studies. Unfortunately, the magnitude reported in the seismic catalogue of Mt. Etna is not homogenous.  Until 2005 only the duration magnitude (M<sub>D</sub>) is available, though since then the more stable local magnitude (M<sub>L</sub>) has also been calculated. To overcome this limitation, earthquake data recorded at Mt. Etna during the period 2005 – 2014 were used to derive a new relationship between local and duration magnitude, by applying the General Orthogonal Regression (GOR) which is an alternative to least squares when the ratio between errors on the independent and the dependent variables can be estimated. The relationship obtained is:</p><p class="Testoformula">     M<sub>L</sub> = 1.164 (± 0.011) * M<sub>D</sub> - 0.337 (± 0.020)                                          </p><p> The new relationship allows to back-extend the local magnitude dataset to cover a period of about 15 years.</p>

Abstract. Previous research suggests that parenting style influences the development of the needs for achievement, power, and affiliation. The present study investigated the relationship between parenting style and another important motive disposition – the need for autonomy – in a sample of Singapore university students ( N = 97, 69% female), using a cross-sectional and retrospective design. It was predicted that an authoritative perceived parenting style would relate positively to the implicit need for autonomy ( nAut), the explicit need for autonomy ( sanAut), and the congruence between these two motive dispositions. Authoritative maternal parenting was found to positively associate with sanAut, while maternal parenting was not found to associate with nAut, or with nAut/ sanAut congruence. Paternal parenting was not associated with any of the dependent variables.

The Relationship

Small and medium enterprises (SMEs) are considered as foundation stones of economic development and growth of any economy (Centobelli, Cerchione, & Esposito, 2019). Performance of SMEs is of fundamental significance for all developed as well as developing nations. Similarly, Pakistan is no exception to aforementioned fact. The economic development and growth of Pakistan depend on the performance of SMEs to a great extent. Like, most countries in the world, SMEs comprise more than 90% of total business entities in Pakistan (Degong et al., 2018; Waqas & Nawaz, 2019) and leather industry in one that is attracted by the researchers of present study. Constraints in the growth of leather industry of Pakistan include, lack of skilled human capital, rising cost of production, lack of modern-day knowledge about new products and processes, low profitability and lack of capability to penetrate into international markets, lack of market research, access to finance, intensive competitive rivalry (Khalique et al., 2011; Daily Times, 2016, Awan et al., 2019). Few studies have revealed mixed findings regarding the relationship between knowledge management and firm performance and there is abundance of literature that demonstrates the presence of significant and positive relationship between Market Orientation and Firm performance (Slater & Narver , 1995; Baker & Sinkula, 2009; Udriyah, Tham, & Azam, 2019). On the other hand, some studies have argued that there is no direct and significant relationship between Market Orientation and Firm Performance (Polat & Mutlu, 2012; Shehu & Mahmood, 2014). Moreover, keeping in view the mixed and inconclusive findings regarding the relationship between cause and effect variables, it is appropriate to introduce moderating variables that can significantly influence the relationship between independent and dependent variables as recommended by Baron and Kenny (1986). Access to Finance and Competitive Environment can be served as prospective moderators which are quite appropriately related to proposed variables of the study (Prajogo & Oke, 2016; Rogo et al., 2016; Jaworski & Kohli, 1993) which are quite appropriately related to selected variables of the study. Thus, the research problem expressed that "Access to finance and competitive environment can potentially moderates and affect the relationship between independent and dependent variables. Hence, based on the past literature and aforementioned discussion, the present study intended to examine the moderating effects of Access to Finance and Competitive Environment on the Relationship between Human Capital, Knowledge Management, Market Orientation and SMEs Performance in Leather Industry of Pakistan".

The Relationship

Students without prior research experience may not know how to conceptualize and design a study. This article explains how an understanding of the classification and operationalization of variables is the key to the process. Variables describe aspects of the sample that is under study; they are so called because they vary in value from subject to subject in the sample. Variables may be independent or dependent. Independent variables influence the value of other variables; dependent variables are influenced in value by other variables. A hypothesis states an expected relationship between variables. A significant relationship between an independent and dependent variable does not prove cause and effect; the relationship may partly or wholly be explained by one or more confounding variables. Variables need to be operationalized; that is, defined in a way that permits their accurate measurement. These and other concepts are explained with the help of clinically relevant examples.

The Relationship

The study attempts to figure out the relationship between the performance of the firms and corporate governance in Pakistan. Governance mechanisms used in this study are CEO duality, Independence of Board, Size of Board, and Ownership Concentration. While, the ROA and ROE have been used as dependent variables to measure the performance of firms. Using regression analysis technique on 10 listed firms trading over four years from 2014-2017, the results have been derived. The data regarding all the variables have been collected from all the companies’ annual reports. The discoveries of the study direct that fundamentals of corporate governance such as the Size of the Board, Ownership, and Duality Concentration of CEO have negative effects on performance of organization, as measured by ROA and ROE. While Board independence positively affects the performance of firms. The results are thus significant and provide valuable information for the decision makers about the research issues under consideration.

The Relationship

The purpose of the present study was to investigate the relationship between anomie theory, as measured by Srole's Anomie Scale, and the respondents self-admitted drug use (alcohol, marijuana, tobacco, amphetamines, and barbiturates). An analysis of self-reported drug use data was conducted of a general Texas adult population. This analysis included a series of bivariate cross comparison correlations between the independent variable (anomie) and the dependent drug variables. The relationship between the independent and dependent variables were further examined by calculating the correlation and level of significance within selected categories of several demographic (age, race, sex, education, income, and marital status) control variables. The results indicated that anomie was significantly correlated with several of the drug variables. However, these associations were extremely weak and of little explanatory value. It was concluded that, within the framework of this analysis, anomie theory fails to provide an adequate explanation for the use of drugs.

Purpose This paper aims to investigate the relationship between corporate governance and auditors switching of listed companies on the Tehran Stock Exchange. Design/methodology/approach To achieve the objectives of this study, 12 hypotheses developed which and tests the relationship between corporate governance and selecting and switching auditors in Iran during 2008-20014 by selecting 116 listed companies on the Tehran Stock Exchange. To test the hypotheses, the cross-sectional time-series nature of research variables data, panel analysis is used. Also, to investigate the relationship between independent and dependent variables in each year, the logistic regression is used. Findings The results of the study indicate that there is a weak relationship between corporate governance auditors switching. Therefore, it could be concluded that there are some other effective factors on which selecting and switching auditors in studied companies are more dependent. Originality/value The current study is almost the first study which has been conducted in Iran, so the results of the study may be beneficial to the Iranian conditions as well as other developing countries.

It was hypothesised that large rotary dairies (>60 clusters) are not more operator efficient than medium-sized rotaries (40–60 clusters). This was tested by collecting and analysing milking data, during peak and late lactation, from block calving herds milked in rotary dairies fitted with electronic milk meters. Data were collected from a total of 61 unique farms around New Zealand, with rotary dairies ranging in size from 28 to 80 clusters, for two 5-day periods during spring (September–November 2010; 47 farms; average milk yield 23.1 kg/day) and autumn (February–April 2011; 60 farms; average milk yield 16.4 kg/day). A telephone survey was conducted to collect basic farm details: size, land area, the number of herds managed (including hospital herds), number of operators in the dairy and total labour input. A site visit was conducted to collect data such as the number of bails/stalls over the entrance and exit of the platform. The herd management software on each farm was programmed to record similar fields for each of the six machine manufacturers represented. Variables recorded included cow, date, identification time, bail number, milk yield, milking duration, and average milk flow rate. Calculations were performed to determine the number of cows milked and milk harvested per hour as well as the operator efficiency values for these measures and an estimate of cluster utilisation. Mixed models were used to determine the relationship between the dependent variables, cows milked per hour, milk harvested per hour, cows milked per operator per hour, milk harvested per operator per hour, and cluster utilisation, and the independent variables collected. Cows milked and milk harvested per hour increased linearly with rotary size, during both spring and autumn and there was a quadratic relationship between operator efficiency measures and rotary size, which peaked at ~60 clusters. Cluster utilisation, the amount of time clusters were harvesting milk out of the plant running time, was estimated at 46 ± 6%. Larger rotary dairies on average achieved greater throughput; however, they were not more operator efficient than medium-sized rotaries. Thus, large rotary dairies are best suited to farms where the additional throughput is required.
