Does human capital matter? A meta-analysis of the relationship between human capital and firm performance

Theory at both the micro and macro level predicts that investments in superior human capital generate better firm-level performance. However, human capital takes time and money to develop or acquire, which potentially offsets its positive benefits. Indeed, extant tests appear equivocal regarding its impact. To clarify what is known, we meta-analyzed effects drawn from 66 studies of the human capital-firm performance relationship and investigated 3 moderators suggested by resource-based theory. We found that human capital relates strongly to performance, especially when the human capital in question is not readily tradable in labor markets and when researchers use operational performance measures that are not subject to profit appropriation. Our results suggest that managers should invest in programs that increase and retain firm-specific human capital.     

Stephen Clark's Green Holism

S.R.L. Clark is a prominent defender of environmental holism and an advocate of the better treatment of other species. Not coincidentally, he is also a defender of a Neoplatonic Theism which holds that (a) the presuppositions of reason have theistic implications and (b) the point of the world is to exemplify beauty, or all the forms of beauty. Here I examine certain aspects of his view. I do so because I'm drawn to his main holist conclusion: we should live according to those rules that will allow as many creatures as possible, of as many kinds, their best chance of living a satisfactory life according to their kind. However, I express doubts about his general route to the principle.     

Callicott's Land Communitarianism

In his most recent collection of papers, J. Baird Callicott has continued to advance a communitarian environmental ethic inspired by the mid–century "land ethic" writings of Aldo Leopold. One subject of concern is a dilemma. Either: the position is open to a charge of "eco–fascism" because it holds that only one maximal community fundamentally matters and interests of smaller communities and individuals can be swamped by a fundamental concern with the whole. Or: it is a "paper tiger" because it says that many communities fundamentally matter, but offers no advice about how we are settle prima–facie conflicts of obligations tied to our various communities. Callicott now offers two new second–order priority principles designed to steer the communitarian position through the dilemma. I outline the relevant parts of his new position. However, I argue that one of the principles ends up offering no coherent advice over the priority of the very communities that inspire interest in the position of Leopold. Callicott proposes that the more intimate and venerable of our communities should have priority, but these elements can come apart in the relevant cases     

Gender, Internet identification, and Internet anxiety: correlates of Internet use.

This paper reports a study that investigated the effects of gender, Internet anxiety, and Internet identification on use of the Internet. The study involved 608 undergraduate students (490 females and 118 males). We surveyed the students' experience with the Internet, as well as their levels of Internet anxiety and Internet identification. We found a number of gender differences in participants' use of the Internet. Males were proportionally more likely to have their own web page than were females. They used the Internet more than females; in particular, they were more likely to use game websites, to use other specialist websites, and to download material from the Internet. However, females did not use the Internet for communication more than males. There was a significant positive relationship between Internet identification and total use of the Internet, and a significant negative relationship between Internet anxiety and total use of the Internet. Controlling for Internet identification and Internet anxiety, we found a significant and negative correlation between gender and use of the Internet. In total, all three of our predictors accounted for 40% of the variance in general Internet use: with Internet identification accounting for 26%, Internet anxiety accounting for 11%, and gender accounting for 3%.     

Situational Content Moderates the Association Between the Big Five Personality Traits and Behavioral Effectiveness

It has been suggested that self-regulatory goal processes are pervasive and powerful determinants of human behavior. Behavior, in turn, is thought to influence both emotions and cognitions to affect future self-set goals. Although determinants and consequences of self-set goals have been examined independently in past research, there is a paucity of theoretical integration across motivational theories. In this article, major elements from social-cog- nitive and attribution theories-and some elements from expectancy and con- trol theories-are integrated with goal theory to develop a cyclical model of self-set goals. In the development and discussion of this model, we present ar- guments for (a) how self-set goals are chosen, (b) how self-set goals affect subsequent behavior, and (c) how self-set goals change over time. Hypotheses are proposed, theoretical implications are discussed, and future research di- rections are suggested.     

Instrumentation and software report: Computer-assisted coding of videotape material

The coding system described was originally devised to facilitate the analysis of mother-infant interaction. Our aims were to provide accurate measures of the duration of different activities, to enable identification of particular actions in order to carry out sequential analyses, and to allow systematic assessment and improvement of reliability. At the time recording began, there appeared to be no readily available systems which achieved all of these aims. The system described here enables coded videotape material to be examined with the assistance of a computer. This is implemented through two subsystems, those of record and playback. In the playback subsystem the behaviour units identified by a coder are mapped on to this record. This results in a protocol of behaviour on a highly accurate time base.     

When training with a partner is inferior to training alone: the importance of dyad type and interaction quality

Dyad training, where trainees learn in pairs but ultimately perform individually, has been shown to be an effective method for training some skills. The effectiveness of this approach, however, may be tied to the type of task to be trained and the quality of the interaction in the dyad. We report two studies on the effectiveness of dyad training and the role of metacognitive activity for learning a software program. In Study 1, participants completed training alone or with a partner. Performance was assessed individually immediately after training and again after a 1-week nonuse interval. Results of Study 1 suggested that learning retention is superior when people are trained individually. Study 2 examined performance for individuals, task-switching dyads, and interdependent dyads. Results also showed that performance for individuals was superior to dyads and that the type of dyad collaboration did not affect performance. However, partner-prompted metacognitive activity was helpful for interdependent dyads and harmful for task-switching dyads, suggesting that the quality of collaboration varies by dyad type. Our findings suggest that dyad training may not be effective for all types of tasks. Possible boundary conditions for effective dyad training are discussed.     

Effects of response preference on resistance to change

Treatments based on differential reinforcement of alternative behavior, such as functional communication training, are widely used. Research regarding the maintenance of related treatment effects is limited. Nevin and Wacker (2013) provided a conceptual framework, rooted in behavioral momentum theory, for the study of treatment maintenance that addressed two components: (a) reemergence of problem behavior, and (b) continued expression of appropriate behavior. In the few studies on this topic, focus has been on variables impacting the reemergence of problem behavior, with fewer studies evaluating the persistence of appropriate behavior. Given the findings from applied research related to functional communication training, variables related to response topography, such as response preference, may impact this aspect of maintenance. In the current study, the impact of response preference on persistence was evaluated in the context of functional communication training for individuals who did not exhibit problem behavior (Experiment 1) and for individuals with a history of reinforcement for problem behavior (Experiment 2). High‐preferred mands were more persistent than low‐preferred mands. These findings suggest that response related variables, such as response preference, impact response persistence and further suggest that response related variables should be considered when developing interventions such as functional communication training.     

Video training of imagery for mature adults

To examine the effectiveness of videotaped memory training, two groups of middle-aged and older adults were given imagery training that included videotaped presentation of interactive imagery for object location recall and linking items on a list, and the image-name match method for name recall. The training group performed significantly better than the waiting list on the initial post-test, and the two groups were comparable after both groups had received training. Evidence for both maintenance and generalization was found. Videotaped presentation of imagery training is effective for mature adults as a self-paced at-home intervention, and has cost-saving advantages over the predominant training methodology.
