This study investigates the moderating effects of age, experience and educational qualification on the relationship between uncertainty and subjective task complexity among lawyers working in private law firms in Lagos State, Nigeria.

A survey method was adopted and data were gathered using questionnaires. The analysis was carried out based on partial least squares structural equation modelling using SmartPLS 2.0 M3 software.

Results showed that the effect of uncertainty on subjective task complexity is significantly moderated by age, educational attainment, experience of the lawyers under study.

Although data were collected in the most populated state and commercial hub of Nigeria, generalisation based on findings may still need to be made with caution.

Attainment of higher educational qualification is highly important for lawyers even though the minimum requirement to practice as a lawyer is a degree. Lawyers with higher degrees (LLM and PhD) had less uncertainty and perceived their tasks to be less complex compared to their counterparts who had the first degree (LLB).

The demographic profile of professionals (age, education and experience) has proven to have an impact on their perception about task complexity as determined by uncertainty as found in this study.

One core element of interactive information retrieval (IIR) experiments is the assignment of search tasks. The purpose of this paper is to provide an analytical review of current practice in developing those search tasks to test, observe or control task complexity and difficulty.

Over 100 prior studies of IIR were examined in terms of how each defined task complexity and/or difficulty (or related concepts) and subsequently interpreted those concepts in the development of the assigned search tasks.

Search task complexity is found to include three dimensions: multiplicity of subtasks or steps, multiplicity of facets, and indeterminability. Search task difficulty is based on an interaction between the search task and the attributes of the searcher or the attributes of the search situation. The paper highlights the anomalies in our use of these two concepts, concluding with suggestions for future methodological research related to search task complexity and difficulty.

By analyzing and synthesizing current practices, this paper provides guidance for future experiments in IIR that involve these two constructs.

The purpose of this article is to understand the role of individual and relational self‐concepts on various team processes and outcomes in a team context.

Participants (n=470) worked in dyads on a computer‐based truck dispatching task, deciding as a team which task activities to perform and in what order. The authors assessed differential relationships between individual and relational self‐concepts and various team processes (e.g. trust) and outcomes (satisfaction).

Subjective task complexity was influenced primarily by individual self‐concept, specifically their core self‐evaluations. Trust in others was influenced primarily by individuals' relational self‐concepts, specifically their teamwork predisposition. Intrinsic motivation and satisfaction were influenced by both individual and relational self‐concepts.

Future research should examine these effects in teams larger than dyads, with other types of tasks, over longer time periods, and with non‐college student samples.

Depending on the task type, a practitioner might cue different self‐concepts to increase individuals' focus on team performance, individual performance, or both. For example, if the team task is highly interdependent and reciprocal in nature, then the team can be trained together or provided information to cue relational self‐concept.

This paper focuses on the construct of individual and relational self‐concepts and their effects on individual functioning in a team context. The results support and extend prior research by demonstrating that outcomes in a team context can be identified and examined in relation to individual conceptions of the self, relational conceptions of the self, or by both.

This paper aims to examine the effect of shared leadership on both quantity and quality of team performance, predicting that shared leadership enhances performance by affecting quantity (level of performance) as well as quality (team errors). In addition, this paper also investigates the role of perceived task complexity in moderating the effect of sharing leadership on team performance.

In total, 26 teams (N = 78) were asked to work on an interdependent team-task, where they engaged in a laboratory team decision-making exercise.

Results revealed that teams sharing leadership made fewer errors. They achieved higher levels of quality of performance. As predicted, this effect was stronger when team members perceived the task as highly complex, even though objective task difficulty was constant.

This study extends current literature on shared leadership by documenting that sharing the lead in teams can also improve the quality of team performance and that perceived complexity of tasks is an important moderator of this effect.

Based on the findings, influencing perceptions of task complexity can be considered as an important strategy to stimulate shared leadership in teams.

Using social network approach, the authors showed that shared leadership is an important tool for preventing team errors and offer a new explanation for inconsistent findings from recent meta-analyses by showing that perceived task complexity moderates the effects of shared leadership. Additionally, this study offers an original team task for investigating shared leadership in teams.

The aim of the study is to analyse theory growth in information science by using a case from information seeking studies. Scientific growth is identified with the growth of theories. Three contexts of theoretical work are differentiated: unit theories, theoretical research programmes and metatheories. For analysis of theory growth tools based on the current theory of science are needed. The study introduces tools for the analysis of theory growth and theory reconstruction and applies them to analysis of a theory on information seeking. Tools include the systematisation and formalisation of theories. The usefulness of these tools is illustrated by reconstructing a theory used in a current information seeking study. It is shown that they help in specifying the theory in the following ways: 1. in stating the central concepts and their relations; 2. in revealing implicit restrictions of the theory; and 3. in facilitating the derivation of additional hypotheses from the theory’s axioms, especially by showing the mechanisms which interconnect the concepts of the theory. The results of reconstruction, specification and enrichment of the theory show future prospects for developing it and thus it creates potential growth of knowledge within the theory of information seeking.

The purpose of this paper is to investigate the effects of self-efficacy, process feedback and task complexity on decisions by managers to continue or discontinue a new product after receiving negative performance feedback.

This paper uses a classroom experiment design and uses logistic regression and a chi-square test to analyze the data.

The findings of this paper show that self-efficacy, process feedback and task complexity have not only main effects but also interactive effects on managers’ go or no-go decisions; further, the main effects are mediated by interactions. The effect of self-efficacy is moderated by process feedback and task complexity. Process feedback and task complexity also have an interactive effect on decisions about new products by decision-makers.

This paper extends the theory of escalation of commitment (EOC) by showing that self-efficacy, process feedback and task complexity can influence decision-makers’ go or no-go decisions after they have received negative performance feedback.

This paper provides useful guidelines for managers on how to reduce the likelihood of EOC.

The originality and value of this paper lie in its being the first to examine the effects of process feedback and task complexity on the EOC.

Effort by managers and academics have been applied to understand elements that improving organizational performance and results. This study aims to analyze the relationship among job performance, job crafting, work complexity and learning support. The authors conducted a cross-sectional survey in a study with a regression hierarchical (i.e. multilevel) design.

Sample included 530 respondents of both sexes with ages ranging from 17 to 68 (M = 33.9; SD = 9.75). Participants were employees from 53 public and private organizations located in the Southeast of Brazil. They answered the scales: General Self-Assessment Scale of Job Performance, Job Crafting Behaviors, Learning Support and Subjective Task Complexity.

The results indicated that variance in job performance due to the differences among the organizations and learning support can explain 22% of variance at this level. Job crafting explained 22% of the job performance variance at level 1 (worker). It is concluded that the development of actions concerning job crafting and the relationship with the work context predict performance at work. Thus, the authors highlight the importance of maintaining individual-focused management practices, meaning that focusing on workers development promotes good results at the organization.

Results revealed practical implications through individual performance considered in a multilevel perspective both in Levels 1 and 2, which is not the most common for this variable. They could be especially important in scenarios that will demand adaptability and work modification, as the actual ones were observed in the contemporary world of work.

Although scholars have provided sufficient empirical evidence on the effectiveness of organizational rewards in managing knowledge sharing, little attention has been paid to the relationship between organizational rewards and knowledge hiding. Drawing on self-determination theory (SDT), this study aims to investigate the effects of financial and nonfinancial rewards on employees' knowledge-hiding behavior as well as the moderating role of task attributes.

This paper examines the hypotheses by conducting a time-lagged survey from a sample of 186 knowledge workers in Chinese high-tech firms.

The findings of this study reveal that financial rewards are positively associated with knowledge hiding, whereas nonfinancial rewards have a negative effect on knowledge. Moreover, task interdependence significantly moderates the effects of organizational rewards on employees' knowledge-hiding behavior. In addition, the interaction between nonfinancial rewards and task complexity is negatively related to knowledge hiding.

This study is one of the first to investigate the effects of financial rewards and nonfinancial rewards on employees' knowledge-hiding behavior, as well as the moderating roles of task interdependence and task complexity.

The article focuses upon the concept of self‐service within the service sector. The nature and growth, as well as the present and potential use of self‐service are analysed and explored. Starting with the service industry, several common classification and evaluation schemes are reviewed. Recent contributions to the understanding of the self‐service industry are next discussed. A model of the self‐service sector is proposed which incorporates attributes drawn from three major sectors: the consumer, the organisation, and the environment. Examples and hypotheses to be explored are included.

To design effective task-responsive search systems, sufficient understanding of users’ tasks must be gained and their characteristics described. Although existing multi-dimensional task schemes can be used to describe users’ search and work tasks, they do not take into account the information use environment (IUE) that contextualises the task. The paper aims to discuss these issues.

With a focus on English primary schools, in four stages a multi-dimensional task scheme was developed that distinguishes between task characteristics generic to all environments, and those that are specific to schools. In Stage 1, a provisional scheme was developed based upon the existing literature. In the next two stages, through interviews with teachers and observations of school children, the provisional scheme was populated and revised. In Stage 4, whether search tasks with the same information use can be distinguished by their characteristics was examined.

Ten generic characteristics were identified (nature of work task, search task originator, search task flexibility, search task doer, search task necessity, task output, search goal, stage in work task, resources and information use) and four characteristics specific to primary schools (curricular area, use in curricular area, planning and location). For the different information uses, some characteristics are more typical than others.

The resulting scheme, based on children’s real-life information seeking, should be used in the design and evaluation of search systems and digital libraries that support school children. More generally, the scheme can also be used in other environments.

This is the first study to develop a multi-dimensional task scheme that considers encompasses the IUE.
