Warehouse productivity depends on the efficiency and effectiveness of the operators and the equally capable and optimized Warehouse Management Systems (WMS) system. The warehouse operators come with a diverse skill set and experience to perform the job. Likewise, the WMS system could be simple or complex depending upon how it is customized. Also, there are technological infrastructure limitations that hinder the ability of the operator to perform the job. This research paper outlines the result of a survey conducted over 200 respondents to find the major human and technological factors and their impact on warehouse productivity. The questionnaire used a Likert scale where the respondents had to agree from one (1) to five (5) among fourteen (14) statements. Factor analysis is used to identify the correlation among those factors. The results show the most statistically significant correlations, and for future research an extended sample size can be targeted.

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Sexualization has been posited to be a part of a larger process of socialization with negative implications (APA, 2010; Ward, 2016). Recent reviews of gender-based violence and exploitation have focused on important elements that highlight the impact of the pervasive experiences of sexual objectification and sexual commodification on women and girls, but relatively limited literature has explored domains of men's sexualizing behaviors. Using the theoretical domains outlined in the APA Task Force Report on the Sexualization of Girls (APA, 2010), the present study developed and validated a measure of men's sexualizing behaviors toward women (MSBWS) on a sample of 308 adult males (ages 18-34). Using exploratory factor analysis, results indicated three-factors that defined the MSBWS: Covert, Commodified, and Overt Sexualization. Analyses also revealed the MSBWS to have high reliability for the overall scale as well as the three subscales. Evidence for construct validity was revealed in significant correlations with all criterion variables (e.g., attitudes of sexual objectification, traditional masculinity and sexual aggression) and suggest broad implications that men's sexualizing behaviors is a measurable construct. Future research may further validate the MSBWS using confirmatory factor analysis on independent samples and examine relevant variables of the possible harm of sexualizing behaviors.

Purpose The overall purpose of this paper is to determine to what extent organizational citizenship behaviors predict followership behaviors within medical organizations in the USA. This is the first part of a two-part article. Part 1 will refine an existing followership instrument. Part 2 will explore the relationship between followership and organizational citizenship. Design/methodology/approach Part 1 of this survey-based empirical study used confirmatory factor analysis on an existing instrument followed by exploratory factor analysis on the revised instrument. Part 2 used regression analysis to explore to what extent organizational citizenship behaviors predict followership behaviors. Findings The findings of this two-part paper show that organizational citizenship has a significant impact on followership behaviors. Part 1 found that making changes to the followership instrument provides an improved instrument. Research limitations/implications Participants in this study work exclusively in the health-care industry; future research should expand to other large organizations that have many followers with few managerial leaders. Practical implications As organizational citizenship can be developed, if there is a relationship between organizational citizenship and followership, organizations can provide professional development opportunities for individual followers. Managers and other leaders can learn how to develop organizational citizenship behaviors and thus followership in several ways: onboarding, coaching, mentoring and career development. Originality/value In Part 1, the paper contributes an improved measurement for followership. Part 2 demonstrates the impact that organizational citizenship behavior can play in developing high performing followers.

During the recent era of big data, a huge volume of unstructured data are being produced in various forms of audio, video, images, text, and animation. Effective use of these unstructured big data is a laborious and tedious task. Information extraction (IE) systems help to extract useful information from this large variety of unstructured data. Several techniques and methods have been presented for IE from unstructured data. However, numerous studies conducted on IE from a variety of unstructured data are limited to single data types such as text, image, audio, or video. This article reviews the existing IE techniques along with its subtasks, limitations, and challenges for the variety of unstructured data highlighting the impact of unstructured big data on IE techniques. To the best of our knowledge, there is no comprehensive study conducted to investigate the limitations of existing IE techniques for the variety of unstructured big data. The objective of the structured review presented in this article is twofold. First, it presents the overview of IE techniques from a variety of unstructured data such as text, image, audio, and video at one platform. Second, it investigates the limitations of these existing IE techniques due to the heterogeneity, dimensionality, and volume of unstructured big data. The review finds that advanced techniques for IE, particularly for multifaceted unstructured big data sets, are the utmost requirement of the organizations to manage big data and derive strategic information. Further, potential solutions are also presented to improve the unstructured big data IE systems for future research. These solutions will help to increase the efficiency and effectiveness of the data analytics process in terms of context-aware analytics systems, data-driven decision-making, and knowledge management.

Stock assessment models are fitted to abundance-index, fishery catch, and age–length–sex composition data that are estimated from survey and fishery records. Research has developed spatiotemporal methods to estimate abundance indices, but there is little research regarding model-based methods to generate age–length–sex composition data. We demonstrate a spatiotemporal approach to generate composition data and a multinomial sample size that approximates the estimated imprecision. A simulation experiment comparing spatiotemporal and design-based methods demonstrates a 32% increase in input sample size for the spatiotemporal estimator. A Stock Synthesis assessment used to manage lingcod (Ophiodon elongatus) in the California Current also shows a 17% increase in sample size and better model fit using the spatiotemporal estimator, resulting in smaller standard errors when estimating spawning biomass. We conclude that spatiotemporal approaches are feasible for estimating both abundance-index and compositional data, thereby providing a unified approach for generating inputs for stock assessments. We hypothesize that spatiotemporal methods will improve statistical efficiency for composition data in many stock assessments and recommend that future research explore the impact of including additional habitat or sampling covariates.

Keywords: confidence intervals, Cronbach's alpha, effect size, factor analysis, hypothesis testing, sample size, structural equation modelingAbstract. The purpose of this paper is to contribute to fulfilling the objectives of social sciences research such as proper estimation, explanation, prediction and control of levels of social reality variables and their interrelationships, especially when dealing with quantitative variables. It was shown that the sample size or the number of observations to be collected and analyzed is transcendental for the adequacy of the method of statistical inference selected and for the impact degree achieved in its results, especially for complying with reports guidelines issued by the American Psychological Association. Methods and formulations were investigated to determine the sample sizes that contribute to have good levels of estimation when establishing confidence intervals, with reasonable wide and relevant and significative magnitudes of the effects. Practical rules suggested by several researchers when determining samples sizes were tested and as a result it was integrated a guide for determining sample sizes for dichotomous, continuous, discrete and Likert variables, correlation and regression methods, factor analysis, Cronbach's alpha, and structural equation models. It is recommended that the reader builds scenarios with this guide and be aware of the implications and relevance in scientific research and decision making of the sample sizes in trying to meet the aforementioned objectives.Palabras clave: análisis factorial, intervalo de confianza, alpha de Cronbach, modelación mediante ecuaciones estructurales, pruebas de hipótesis, tamaño de muestra, tamaño del efectoResumen.

The purpose was to study the impact of humorous advertisement on purchase decision, and in order to reach this objective, Uf one ads were analysed and compared to other mobile network ads which are being aired, especially in Pakistan’s telecom industry. Mobile users of Pakistan filled the questionnaires which were administered via distributing hard copies and online through Google Forms, from January 2017 to January 2018. Secondary data were collected using different research journals, which included JSTOR, Science Direct and Google Scholar. The planned sample size was 127 respondents. The results showed that humorous advertisement is one of the appeals which breaks the clutter.90% of the respondents said that humorous advertisements greatly affect the purchase decision. Hence, Ufone’s ads are effective. Recommendation for future research would be to study humour in detail, that is, by dividing the humorous appeal in categories like dark humour, slice of life humour and studying their respective impact on customer’s purchase decision.   Keywords: Humorous advertisement, advertisement effectiveness, purchase decision, telecom companies.

Purpose The purpose of this paper is to use institutional theory to develop the constructs of institutional pressures for social compliance and argue for a positive relationship between institutional pressures and Supplier Social Compliance Management System (SSCMS). Moreover, the authors theorize that the impact of institutional pressures on SSCMS is moderated by the supplier’s organizational culture. This is done in a particularly salient context, which is apparel manufacturing in a developing country. Design/methodology/approach The hypothesized model is tested using data of 164 suppliers from the apparel manufacturing sector. PLS-based structural equation modeling is used to test the direct and multi-group moderation hypotheses. Findings Empirical examination provides evidence that institutional pressures have a positive impact on supplier social compliance and the types of organizational culture have varied moderation effects. Research limitations/implications This research is based on cross-sectional data from one industry. Future research should collect data from diverse sectors in different countries. Practical implications The findings suggest that consistent pressures from various stakeholders can increase supplier social compliance. In addition, the partial evidence for moderation effect of organizational culture indicates that supplier’s internal value system’s alignment with social compliance pressures plays an important role in determining how supplier acts on social compliance initiatives. Originality/value The issue of suppliers’ adoption of social compliance management systems has become prominent as a consequence of the shifting of manufacturing to developing countries. However, comprehensive frameworks explaining antecedents of adoption of SSCMS using large-scale empirical data are limited. In addition, findings on the relationship between supplier social sustainability practices and their antecedents are inconsistent.

Online reviews are changing the way that consumers shop and firms respond to consumer feedback. Viewed more broadly, online reviews are a type of information flow altering the functioning of marketing systems at the micro, meso, and macro levels. A systematic review of the past two decades of research shows great attention to the impact of online reviews on information flows, as well as the nuances of micro-and meso-level efficiency outcomes. However, there is scant consideration for the effectiveness related outcomes of online reviews (such as customer well-being, distributive justice, and externalities). Through a macromarketing lens, online reviews are an information flow with the potential to change well-being outcomes for all stakeholders, rather than just a tool to be exploited by firms or consumers. A theoretical framework and a series of questions are presented for future research on how online reviews and more generally information flows between actors may impact the efficiency and effectiveness of a marketing system.
