This Short Methodological Report builds on research about moderation practices by focusing on a marginal effects approach to interpreting how a main effect is informed by the presence of a moderating variable. Following a content analysis of published studies and a survey of management researchers, our findings suggest there is a great deal of confusion about the ways in which to interpret how a main effect may fluctuate owing to a moderating variable. We therefore provide explicit instructions on how to implement and interpret a marginal effects approach that depicts the nature of a main effect in the presence of a moderator. We use different scenarios and examples to illustrate how researchers can employ the marginal effects technique, which provides an indication of the relationship between the independent and dependent variables over different values of the moderator. We argue and demonstrate that the marginal effects approach helps resolve conflicting findings that may arise from using other prevailing techniques to interpret both main effects and moderation.

Main Effects

320 Croatian female students ( M = 20.4 yr.) were recruited to examine the validity and reliability of figural scales using different numbers of stimuli (3, 5, 7, and 9) and different serial presentation (serial and nonserial order). A two-way analysis of variance (4 numbers × 2 orders of stimuli) was performed on ratings of current self-size and ideal size as dependent variables. Analysis indicated a significant main effect of number of stimuli. This, together with post hoc tests indicated that ratings were significantly different for a scale of three figures from scales of more figures, which in turn did not differ among themselves. Main effects of order of stimuli, as well as the interaction, were not significant. The results support the hypothesis that the optimal number of figures on a scale is seven plus (or minus) two.

The purpose of this study was to examine the positive effect of self-monitoring among emotional display rules (fostering positive emotion(FPE) & suppressing negative emotion(SNE)) and consequential work attitude (job burnout & work engagement). A sample of 191 hotel employees were participated in this study and data were analyzed by SPSS. The results are as follows. First, the main effect of FPE on work engagement was supported, but the main effect of SNE on job burnout was not. Second, the main effects of self-monitoring on engagement and burnout were supported. Third, the moderation effects of self-monitoring which buffer the relationship of SNE on burnout and which facilitate the relationship FPE on engagement were significant. Finally, the implications and limitations were discussed.

Purpose Previous work has established that advanced bolus location at swallow onset (BLSO) alone is not correlated with an increased swallowing safety risk in healthy seniors. The primary goal of this retrospective study was to examine whether healthy seniors systematically alter their laryngeal vestibule closure reaction time (LVCrt) to maintain a safe swallow in the context of advanced BLSO. The secondary goal was to determine if longer LVCrt distinguished Penetration–Aspiration Scale (PAS; Rosenbek, Robbins, Roecker, Coyle, & Wood, 1996) scores of 1 versus 2. Method Videofluoroscopy studies from 43 healthy seniors (21 men, 22 women; M age = 76.7 years, SD = 7.2) were analyzed. LVCrt was calculated for 3 × 5 ml and 3 × 20 ml thin liquid barium boluses per participant. PAS and BLSO (Modified Barium Swallow Impairment Profile Component 6) were scored for all swallows. Reliability (intraclass correlation coefficient > .75) was established on all measures. A linear mixed-effects regression was run to examine the effect of PAS and BLSO on LVCrt while controlling for bolus volume and repeated swallow trial. Results There was a main effect of BLSO ( F = 4.6, p = .004) and PAS ( F = 29.3, p < .001) on LVCrt. Post hoc pairwise comparisons revealed that LVCrt was significantly faster in BLSO scores of 3 (pyriforms) compared to scores of both 0 (posterior angle of the ramus) and 1 (valleculae). Significantly prolonged LVCrt was observed in PAS scores of 2 in comparison to 1. No significant main effects of bolus volume or trial, or interactions, were observed. Conclusions Our findings suggest that healthy seniors compensate for advanced BLSO by increasing their LVCrt. Furthermore, faster LVCrt was shown to distinguish PAS scores of 1 versus 2. Additional work should explore the relationship between LVCrt, BLSO, and PAS scores in dysphagic populations, specifically those with known sensory impairments.

This study extends previous research on the expectancy construct of the expectancy-value theory of motivation developed by Pintrich. In addition to value and expectancy for success, it is proposed that people take into account how much effort is required to complete a task. A 2 × 2 × 2 analysis of variance design was used to investigate the relationship of Difficulty, Consequence, and Required Effort on the willingness of participants to complete a task. The dependent variable was the score obtained from completing statistical problems that varied in difficulty and effort required to complete. 128 students at a public university were participants. Analysis showed significant main effects and an interaction for difficulty and required effort, but no main effect for consequence. Results are discussed in terms of creating optimal motivation for classroom tasks and for both classroom and standardized examinations. Implications for students in subject pools are also discussed.

The purpose of this study was to determine the use of visual feedback by typists at various skill levels. 73 volunteers from 5 college typewriting classes completed three 1-min. timed typewriting trials and four 3-min. trials. Subjects' gross words per minute were used to classify subjects by skill level into five groups: 35 gross words per minute or less, 36 to 45, 46 to 55, 56 to 65, or 66 or more gross words per minute. Subjects performed each of the four 3-min. trials in a different condition of visual feedback: unrestricted visual feedback, visual feedback for response confirmation, visual feedback for response guidance, and restricted visual feedback. Three analyses of variance (groups × conditions) were calculated using gross words per minute, percent dependable feedback, and total errors as dependent variables. Main effects of groups and conditions were significant for gross words per minute and percent dependable feedback. Only the main effect of conditions was significant for total errors. There were no statistically significant interactions. Results suggest that typists at different skill levels use visual feedback similarly, with the best over-all performance occurring when visual feedback is available and used for response guidance.

Abstract. TV news are essentially cultural phenomena. Previous research suggests that the often-overlooked formal and implicit characteristics of newscasts may be systematically related to culture-specific characteristics. Investigating these characteristics by means of a frame-by-frame content analysis is identified as a particularly promising methodological approach. To examine the relationship between culture and selected formal characteristics of newscasts, we present an explorative study that compares material from the USA, the Arab world, and Germany. Results indicate that there are many significant differences, some of which are in line with expectations derived from cultural specifics. Specifically, we argue that the number of persons presented as well as the context in which they are presented can be interpreted as indicators of Individualism/Collectivism. The conclusions underline the validity of the chosen methodological approach, but also demonstrate the need for more comprehensive and theory-driven category schemes.

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.

Abstract This four-part series of papers addresses the problem of systematic determination of the influence of several tire factors on tire treadwear. Both the main effect of each factor and some of their interactive effects are included. The program was also structured to evaluate the influence of some external-to-tire conditions on the relationship of tire factors to treadwear. Part I describes the experimental design used to evaluate the effects on treadwear of generic tire type, aspect ratio, tread pattern (groove or void level), type of pattern (straight rib or block), and tread compound. Construction procedures and precautions used to obtain a valid and functional test method are included. Two guiding principles to be used in the data analyses of Parts II and III are discussed. These are the fractional groove and void concept, to characterize tread pattern geometry, and a demonstration of the equivalence of wear rate for identical compounds on whole tread or multi-section tread tires.

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".
