Instruments for Personnel Selection in the 21st Century: Research and Practice Instruments for Personnel Selection in the 21st Century: Research and Practice This article presents an evidence-based overview of innovative selection techniques that were developed in the last years to provide an answer to key questions concerning the contemporary practice of selection. In addition, we aim to point out gaps in the current knowledge about these novel techniques to guide future research. The article shows that innovative selection instruments such as conditional reasoning tests, integrity tests, and implicit association tests might offer opportunities to measure value-based competencies, and maladaptive traits. Furthermore, contextualized personality questionnaires, business-related intelligence tests, situational judgment tests, and so-called serious games enable organizations to improve their image, which creates branding opportunities to promote the company as an attractive employer. Finally, we conclude by stating that practitioners and researchers face numerous selection challenges. Examples are the selection of a diverse as well as competent workforce and the reliable and valid implementation of unproctored Internet testing.

Camouflage is an important anti-predator strategy for many animals and is traditionally thought of as being tightly linked to a specific visual background. While much work focuses on optimizing camouflage against one background, this may not be relevant for many species and contexts, as animals may encounter many different habitats throughout their lives due to temporal and spatial variation in their environment. How should camouflage be optimized when an animal or object is seen against multiple visual backgrounds? Various solutions may exist, including colour change to match new environments or use of behaviour to maintain crypsis by choosing appropriate substrates. Here, we focus on a selection of approaches under a third alternative strategy: animals may adopt (over evolution) camouflage appearances that represent an optimal solution against multiple visual scenes. One approach may include a generalist or compromise strategy, where coloration matches several backgrounds to some extent, but none closely. A range of other camouflage types, including disruptive camouflage, may also provide protection in multiple environments. Despite detailed theoretical work determining the plausibility of compromise camouflage and elucidating the conditions under which it might evolve, there is currently mixed experimental evidence supporting its value and little evidence of it in natural systems. In addition, there remain many questions including how camouflage strategies should be defined and optimized, and how they might interact with other types of crypsis and defensive markings. Overall, we provide a critical overview of our current knowledge about how camouflage can enable matching to multiple backgrounds, discuss important challenges of working on this question and make recommendations for future research.

Abstract. During the past 20 years, Situational Judgment Tests (SJTs) have developed into a viable tool in personnel selection. Despite their growing popularity, research examining the extent of measurement error is widely lacking. Using reliability generalization, the aim of this article was twofold: (1) establish an estimate for an average coefficient alpha of SJT scores across studies and (2) examine the influence of essential SJT features and selected study variables on score reliability. To handle potential dependent observations a three-level hierarchical linear model was used. The results indicate that the reliability of SJT scores is typically rather low and below recommended levels for high-stakes applications. Additionally, both SJT and study characteristics affect score reliability. Implications for practitioners and researchers are provided to guide an appropriate use of SJTs and to initiate future research.

Integrity Tests

Until recently, research focus has been on a variety of demographic, attitudinal, and organizational variables in predicting and explaining absenteeism. If personality traits predict absenteeism, then it may be possible to use measures of these traits to identify and select job applicants and thereby reduce absenteeism rates. In this research, our goal was to examine whether integrity tests could be used to predict absenteeism. Meta‐analysis was applied to studies of the validity of pre‐employment integrity tests for predicting voluntary absenteeism. Twenty‐eight studies based on a total sample of 13 972 were meta‐analysed. The estimated mean predictive validity of personality‐based integrity tests was 0.33. This operational validity generalized across various predictor scales, organizations, settings, and jobs (SDρ = 0.00). Overt integrity tests, however, showed much lower predictive validity for absenteeism and greater variability than personality‐based tests (ρ = 0.09; SDρ = 0.16). The results indicate that a personnel selection approach to reducing absenteeism in organizations may be a useful strategy, particularly if personality‐based integrity tests are utilized. Potential explanations for differences between these results and those found for Big Five measures of personality are offered. Future research investigating models of absenteeism should incorporate the personality constructs assessed by integrity tests. Copyright © 2003 John Wiley & Sons, Ltd.

In this article, we target emerging market small and medium-sized enterprise (SME) internationalization by tackling two key questions: (1) What are the issues and challenges facing the emerging market SMEs in the process of internationalization in general and choice of destination in particular? (2) What are the strategies and processes being adopted by SMEs to overcome the challenges and limitations with specific reference to international destinations in developed economies as opposed to emerging markets? As we delve into these twin issues, we develop a conceptual framework, based on our mini case studies of Chinese and Indian SMEs to make complementary contribution to the research on the internationalization of emerging market SMEs. Finally, we pose a number of research questions for future research as the outcome of this article.

We begin by charting the evolution of the dominant perspective on job performance from one that viewed performance as static to one that viewed it as dynamic over long timeframes (e.g., months, years, decades) to one that views it as dynamic over not just long but also short timeframes (e.g., minutes, hours, days, weeks)—and that accordingly emphasizes the within-person level of analysis. The remainder of the article is devoted to the newer, short-timeframe research on within-person variability in job performance. We emphasize personality states and affective states as motivational antecedents. We provide accessible reviews of relevant theories and highlight the convergence of theorizing across the personality and affect antecedent domains. We then focus on several major avenues for future research. Finally, we discuss the implications of these perspectives for personnel selection and performance management in organizations as well as for employees aiming to optimize their job performance.

Aim/Purpose: The goal of this study is to advance understanding of ICT utilization by SMMEs by checking access, ability (in terms of technological skills) and usage of ICT among some SMMEs entrepreneurs operating their businesses in an underdeveloped areas to enhance their business activities in order to utilizes the digital opportunities 21st century digital economies present. Background: In today’s world no nation or region is untouched by the forces of globalization and digital economy. One of the key pioneering forces of globalization is the advances of ICT like internet, social networks, etc. In the sphere of business, this pioneering force has also altered the way businesses and organizations communicate and interact with customers and society at large. Such alternation presents obvious opportunities for wealth creation and growth for businesses and organizations that are well-equipped to take advantages of them. But for those that are less-equipped, particularly SMMEs, globalization can easily lead to fore-closures and marginalization. It is a common knowledge that SMMEs entrepreneurs mostly rely on ICT gadgets like mobile phone, Laptops, Tablets to conduct their business activities as many of them don’t have enough capital to set up offices with necessary equipment. Therefore, using various ICT functions/programs on these ICT devices to enhance their business activities are critical to their businesses in the 21st century digital economies. Methodology: Purposeful sampling was used to approach fifty-four SMMEs entrepreneurs operating their businesses in underdeveloped areas locally called Townships in Buffalo City Metropolitan. Microsoft excel was used in the descriptive statistics. Contribution: This research will add to the growing knowledge ICT usage in SMMEs in the 21st century digital economies. Findings: The results indicate that the participating SMMEs entrepreneurs need to be educated, trained and supported in the use of the ICT applicable to enhance their business activities in order for them to take advantages of 21st century digital economies present. Recommendations for Practitioners: The agencies tasked with looking after SMMEs in South Africa needs to consider the lacked of utilisation of ICTs by SMMEs entrepreneurs operating their businesses in underdeveloped areas as one of the barrier to growing of their businesses and take necessary steps to address it. Recommendation for Researchers: Since age and gender have been proven to be key-moderating variables in many technology acceptance models. There is a need to explore in depth whether the factors of gender and age also act as barriers. Impact on Society: The research will assist stakeholders, policy makers and agencies tasked with looking after SMMEs to identify the barriers hindering SMMEs to grow and address them accordingly. Future Research: More work needs to be done to check whether gender, age of the SMMEs entrepreneurs have some effects on their attitude towards the integration of ICT into their business activities.

Decalepis Arayalpathra

Background: Decalepis arayalpathra (J. Joseph and V. Chandras.) Venter is used primarily for nutrition besides its therapeutic values. Traditional preparations/formulations from its tuber are used as a vitalizer and blood purifier drink. The folklore medicinal uses cover inflammation, cough, wound healing, antipyretic, and digestive system management. A comprehensive review of the current understanding of the plant is required due to emerging concerns over its safety and efficacy. Objective: The systematic collection of the authentic information from different sources with the critical discussion is summarised in order to address various issues related to botanical identity, therapeutic medicine, nutritional usage, phytochemical, and pharmacological potentials of the D. arayalpathra. Current use of traditional systems of medicine can be used to expand future research opportunities. Materials and Methods: Available scripted information was collected manually, from peered review research papers and international databases viz. Science Direct, Google Scholar, SciFinder, Scopus, etc. The unpublished resources which were not available in database were collected through the classical books of ‘Ayurveda’ and ‘Siddha’ published in regional languages. The information from books, Ph.D. and MSc dissertations, conference papers and government reports were also collected. We thoroughly screened the scripted information of classical books, titles, abstracts, reports, and full-texts of the journals to establish the reliability of the content. Results: Tuber bearing vanilla like signature flavor is due to the presence of 2-hydroxy-4-methoxybenzaldehyde (HMB). Among five other species, Decalepis arayalpathra (DA) has come under the ‘critically endangered’ category, due to over-exploitation for traditional, therapeutic and cool drink use. The experimental studies proved that it possesses gastro-protective, anti-tumor, and antiinflammatory activities. Some efforts were also made to develop better therapeutics by logical modifications in 2-Hydroxy-4-methoxy-benzaldehyde, which is a major secondary metabolite of D. arayalpathra. ‘Amruthapala’ offers the enormous opportunity to develop herbal drink with health benefits like gastro-protective, anti-oxidant and anti-inflammatory actions. Results: The plant has the potential to generate the investigational new lead (IND) based on its major secondary metabolite i.e. 2-Hydroxy-4-methoxy-benzaldehyde. The present mini-review summarizes the current knowledge on Decalepis arayalpathra, covering its phytochemical diversity, biological potentials, strategies for its conservation, and intellectual property rights (IPR) status.
