Social Behavior and Personality Patterns of Captive African Elephants

Through the Hamel Center for Undergraduate Research, I received an International Research Opportunities Program (IROP) grant to study the social behaviors of African elephants. My research took place in South Africa with the African Elephant ResearchUnit at Knysna ElephantPark. Elephants live in herds and have very strong social bonds. The social interactions and dominance hierarchy between individuals of a herd depend upon many factors, including maternal lineage, age, sex, and personality traits of the elephants.I studied how social behaviors among captive elephants vary throughout the day on an hourly time scale, if those behavior patterns are related to age, and if handler perceptions of elephant personality are an accurate predictor of those social behaviors.To answer these questions, I spent about six hours in the field, four days a week, observing a herd of seven elephants and recording every time that any of the elephants interacted with each other.I also surveyed the elephant handlers regarding their perceptions of the elephants’ social behaviors and personality.The results of this study aim to give insight into the best management practices for African elephants in captivity, with special consideration for their patterns of social behavior

The relationship of life stage to daily social patterns of captive African elephants (Loxodonta africana) and the correlation of handler perceptions of elephant personality to demonstrated social behaviors

Elephants typically have very strong social bonds, and social interactions can include affiliative, agonistic, or ambiguous behaviors. The social interactions and dominance hierarchy between individuals of a herd depend upon many factors, including maternal lineage, age, and sex. This study was designed to determine how social behaviors among a herd of captive African elephants varied throughout the day and to establish if the frequency of social interactions and age class were correlated. The study also aimed to determine if handler perceptions of elephant personality were an accurate predictor of the type and frequency of social behaviors observed, in addition to the factors stated above. The research was performed at the African Elephant Research Unit at Knysna Elephant Park (KEP) in South Africa. The herd included 7 elephants in 3 age groups: juvenile (0-10 years), young adult (11-20 years), and adult (20+ years). Continuous, all-occurrence sampling of pre-determined affiliative, agonistic, and ambiguous social behaviors was performed for a total of 90.4 hours within a seven-week period. Results indicated that there was a statistically higher rate of affiliative, agonistic, and total social behaviors initiated during mid-morning than during mid-afternoon, but no statistical difference in ambiguous social behaviors initiated throughout the day. Additionally, elephant handlers were individually surveyed regarding perceptions of each elephant’s personality traits, including qualities of dominance, activity level, boldness, confidence, curiosity, sociability, and aggressiveness. This characterization was compared to the previously recorded elephant social behaviors, and results indicated that there was a strong positive correlation between observed agonistic rate of social behavior and rated activity levels. Results are intended to influence the management of captive elephants at KEP and elsewhere

The Work, Family, and Equity Index: How Does the United States Measure Up

As part of the Project on Global Working Families, with the support of the Ford Foundation, the Work, Family, and Equity Index has been developed to measure governmental performance around the world in meeting the needs of working families. The elements in the Index have been selected to comprise an evidence-based set of policies that are important to meeting the needs of working families in general and low- and middle-income working families in particular. Those policies that have achieved widespread recognition based on the weight of the research evidence or consensus in global policy and international agreements are included. To complete the index, data were gathered from 177 countries that represent a wide range of political, social and economic systems

Rural Community Participation, Social Networks, and Broadband Use: Examples from Localized and National Survey Data

Although attention has been given to how broadband access is related to economic development in rural areas, scant consideration has been given to how it may be associated with voluntary participation. This issue is important in that numerous studies have shown how much more vital community participation is in rural areas as compared to suburban and urban places. Drawing on three diverse data sets, we examine the influence of broadband access on community participation. In addition, we explore whether broadband access exerts its influence through, in conjunction with, or independent of social networks. The results suggest that broadband access and social network size have independent effects on volunteering in rural places.rural sociology, social networks, broadband, digital inequality, volunteerism, Community/Rural/Urban Development, Research and Development/Tech Change/Emerging Technologies,

The political risks of technological determinism in rural water supply: A case study from Bihar, India

With the politics of the environment so fundamental to the development process in rural India, this paper analyses the relations between water discourses and drinking water technology. First, the national discourses of water are analysed using key policy and populist documents. Second, the paper presents ethnographic fieldwork studying the politics of drinking water in rural Bihar, where the relative merits of borehole handpumps and open wells are contested. The links between the national discourses and local contestation over appropriate technology are examined. The paper argues both policy and traditionalist perspectives are too technologically deterministic to adequately account for the myriad challenges of delivering rural water supply. The emphasis on technology, rather than service levels, creates the conditions in which capability traps emerge in terms of service provision. This is not only in terms of monitoring regimes but in the very practices of rural actors who use certain water supply technologies under an illusion of safety. With a focus on furthering the policy debate, the paper considers ways forward and suggests that a move from a binary understanding of access to a holistic measure of service levels will reduce the potential for political contestation and capability traps in rural water supply

Extended Photometry for the DEEP2 Galaxy Redshift Survey: A Testbed for Photometric Redshift Experiments

This paper describes a new catalog that supplements the existing DEEP2 Galaxy Redshift Survey photometric and spectroscopic catalogs with ugriz photometry from two other surveys; the Canada-France-Hawaii Legacy Survey (CFHTLS) and the Sloan Digital Sky Survey (SDSS). Each catalog is cross-matched by position on the sky in order to assign ugriz photometry to objects in the DEEP2 catalogs. We have recalibrated the CFHTLS photometry where it overlaps DEEP2 in order to provide a more uniform dataset. We have also used this improved photometry to predict DEEP2 BRI photometry in regions where only poorer measurements were available previously. In addition, we have included improved astrometry tied to SDSS rather than USNO-A2.0 for all DEEP2 objects. In total this catalog contains ~27,000 objects with full ugriz photometry as well as robust spectroscopic redshift measurements, 64% of which have r > 23. By combining the secure and accurate redshifts of the DEEP2 Galaxy Redshift Survey with ugriz photometry, we have created a catalog that can be used as an excellent testbed for future photo-z studies, including tests of algorithms for surveys such as LSST and DES.Comment: 12 pages, 6 figures and 5 tables.
