An Empirical Comparison of Knowledge and Skill in the Context of Traditional Ecological Knowledge

Background We test whether traditional ecological knowledge (TEK) about how to make an item predicts a person’s skill at making it among the Tsimane’ (Bolivia). The rationale for this research is that the failure to distinguish between knowledge and skill might account for some of the conflicting results about the relationships between TEK, human health, and economic development. Methods We test the association between a commonly-used measure of individual knowledge (cultural consensus analysis) about how to make an arrow or a bag and a measure of individual skill at making these items, using ordinary least-squares regression. The study consists of 43 participants from 3 villages. Results We find no association between our measures of knowledge and skill (core model, p \u3e 0.5,R2 = .132). Conclusions While we cannot rule out the possibility of a real association between these phenomena, we interpret our findings as support for the claim that researchers should distinguish between methods to measure knowledge and skill when studying trends in TEK

Videoconferencing As A Tool For Recruiting And Interviewing

The purpose of this pilot study is to explore opportunities for CSX, a Fortune 250 transportation company, to reduce costs associated with recruiting and interviewing potential job candidates.  Videoconferencing technology has been identified as a potential method of reducing these expenses.  It was discovered that recruiters at CSX were spending a great deal of time and money by traveling to universities to recruit students to work for the organization.  Additionally, large sums of money were spent to bring potential job candidates to the headquarters for multiple interviews, which is located in Jacksonville, FL.  This pilot study was intended to enrich the limited body of recent research as it relates to the integration of videoconferencing as a tool for interviewing.  This paper was also intended to gain further insight as to how CSX could benefit through the integration of videoconferencing technology into the human resource selection process in an effort to save time and money.&nbsp

Ephemeral Work Group Formation of Jenu Kuruba Honey Collectors and Late 19th Century Coloado Silver Prospectors

Humans frequently form short-lived cooperative groups to accomplish subsistence and economic tasks. We explore the ecological and cultural factors behind ephemeral work-group formation in two disparate cultural contexts: groups foraging for wild honey in present day South India and groups prospecting for silver ore in the Elk Mountain Mining District of Colorado in the late 19th century. Contrary to traditional economic foraging predictions, we find little evidence that per capita yields are the most important factor in determining size and composition of ephemeral work groups. We explore factors in each of these cultures that may be of importance for group formation such as kinship, reputation, and pleasure. Models that only incorporate economic parameters will make poor predictions of how humans interact with their environments

From Mind to Matter: Patterns of Innovation in the Archaeological Record and the Ecology of Social Learning

Archaeology and cultural evolution theory both predict that environmental variation and population size drive the likelihood of inventions (via individual learning) and their conversion to population-wide innovations (via social uptake). We use the case study of the adoption of the bow and arrow in the Great Basin to infer how patterns of cultural variation, invention, and innovation affect investment in new technologies over time and the conditions under which we could predict cultural innovation to occur. Using an agent-based simulation to investigate the conditions that manifest in the innovation of technology, we find the following: (1) increasing ecological variation results in a greater reliance on individual learning, even when this decreases average fitness due to the costs of learning; (2) decreasing population size increases variability in the types of learning strategies that individuals use; among smaller populations drift-like processes may contribute to randomization in interpopulation cultural diffusion; (3) increasing the mutation rate affects the variability in learning patterns at different rates of environmental variation; and (4) increasing selection pressure increases the reliance on social learning. We provide an open-source R script for the model and encourage others to use it to test additional hypotheses

Cultural Group Selection Plays an Essential Role in Explaining Human Cooperation: A Sketch of the Evidence

Human cooperation is highly unusual. We live in large groups composed mostly of non-relatives. Evolutionists have proposed a number of explanations for this pattern, including cultural group selection and extensions of more general processes such as reciprocity, kin selection, and multi-level selection acting on genes. Evolutionary processes are consilient; they affect several different empirical domains, such as patterns of behavior and the proximal drivers of that behavior. In this target article, we sketch the evidence from five domains that bear on the explanatory adequacy of cultural group selection and competing hypotheses to explain human cooperation. Does cultural transmission constitute an inheritance system that can evolve in a Darwinian fashion? Are the norms that underpin institutions among the cultural traits so transmitted? Do we observe sufficient variation at the level of groups of considerable size for group selection to be a plausible process? Do human groups compete, and do success and failure in competition depend upon cultural variation? Do we observe adaptations for cooperation in humans that most plausibly arose by cultural group selection? If the answer to one of these questions is “no,” then we must look to other hypotheses. We present evidence, including quantitative evidence, that the answer to all of the questions is “yes” and argue that we must take the cultural group selection hypothesis seriously. If culturally transmitted systems of rules (institutions) that limit individual deviance organize cooperation in human societies, then it is not clear that any extant alternative to cultural group selection can be a complete explanation

Group Characteristics Influence Distribution Patterns of Off-Road Vehicle Recreation within a Complex Trail System in Southwest Idaho

Recreation on public lands is growing and is increasingly recognized as an ecosystem service providing improved health, connection to nature, and social time while also disturbing and degrading ecosystems. Human impacts must be managed, but often managers have little information about the factors that affect recreation patterns. We combined data from global positioning system receivers to record off-road vehicle (ORV) travel with a pretrip survey to determine how group characteristics, site experience, site knowledge, and motivation are associated with ORV trip patterns on public lands in southwest Idaho. Spatial and temporal extent and distribution could summarize most variation in ORV trips. Both trip distribution and extent were associated with group characteristics and site knowledge. Spatial and temporal extent was additionally associated with motivations and distribution was associated with riding experience. These findings can help land managers to identify use patterns, direct informational programs, and effect indirect management strategies

Skills, Division of Labor, and Economies of Scale Among Amazonian Hunters and South Indian Honey Collectors

In foraging and other productive activities, individuals make choices regarding whether and with whom to cooperate, and in what capacities. The size and composition of cooperative groups can be understood as a self-organized outcome of these choices, which are made under local ecological and social constraints. This article describes a theoretical framework for explaining the size and composition of foraging groups based on three principles: (1) the sexual division of labor; (2) the intergenerational division of labor; and (3) economies of scale in production. We test predictions from the theory with data from two field contexts: Tsimane\u27 game hunters of lowland Bolivia, and Jenu Kuruba honey collectors of South India. In each case, we estimate the impacts of group size and individual group members’ effort on group success. We characterize differences in the skill requirements of different foraging activities, and show that individuals participate more frequently in activities in which they are more efficient. We evaluate returns to scale across different resource types, and observe higher returns at larger group sizes in foraging activities (such as hunting large game) that benefit from coordinated and complementary roles. These results inform us that the foraging group size and composition are guided by the motivated choice of individuals on the basis of relative efficiency, benefits of cooperation, opportunity costs, and other social considerations

Time Distribution of Faculty Workload at Boise State University

This project’s first phase was to get a general idea of what the average work day looks like for a Boise State University faculty member; from this stage we developed activity definitions to use for the next phase. Thirty faculty members were interviewed by fourteen trained undergraduate research assistants over the course of two weeks on alternating days, April 9-21, 2013. These thirty faculty members represented all colleges of the Boise State University campus, including the Library, providing a total of 166 faculty days’ worth of data. The positions held by each participant ranged between an Assistant Professor and a Department Chair. The time diary method enabled students to document the type and duration of activities, functions, locations, and presence or absence of other types of individuals. Data on general work patterns and activities of BSU faculty are presented and broken out by day of week, type of activity, function, and location. These findings indicate that faculty work more than expected and in a wide range of activities and they work alone much of the time
