  • 31 – Jackass Management Traits1
    Effective Security Management, 2016
    Co-Authors: Charles A. Sennewald, Curtis Baillie
    Abstract:

    The fun, tongue-in-cheek caricatures in this chapter may indeed be the most important part of the book. The chapter points out that even though it is good to understand organizational principles and management techniques, if a manager does not know how to manage and supervise the employees, this learning will be all for naught. There are 32 supervisory and managerial flaws found in organizational life that are described here, and a key is included, to be used as a quick reference to the different kinds of “donkeys” that find their way into positions of leadership.

  • Jackass Management Traits
    Effective Security Management, 2011
    Co-Authors: Charles A. Sennewald
    Abstract:

    This chapter briefly discusses 32 supervisory and managerial flaws found in a security organization. The manager, who strives to be liked by all, gets trapped into avoiding unpopular decisions and ignoring disciplinary problems. In fact, the employees mostly prefer a fair, impartial, predictable, and honest administrator or leader who sets and maintains standards. The manager who ignores the opinions and advice of subordinates denies him- or herself input from the collective wisdom of the group or department. The manager who can create the climate in which employees have some voice in the things that happen and in which they participate or somehow contribute to the operation as team members gets the most out of the employees. The manager who fails to delegate the job properly becomes mired down in relatively unimportant decisions and activities. The subordinates also get easily demoralized as they know that their manager or supervisor would arbitrarily change their plans and decisions in favor of his or hers. A religious or a racial bigot manager consistently breeds discontentment and confrontation in the organization and denies himself or herself and the organization the full spectrum of talent present in the organization. The manager, who acts or overreacts too quickly and reacts to normal problems as crises, tends to blame others for the mess created by them. This leads to secrecy among the subordinates, which then cause breakdown in communications and a vicious circle that causes an unhealthy work environment.

  • MALARIA IN WILD AND CAPTIVE Jackass PENGUINS SPHENISCUS DEMERSUS ALONG THE SOUTHERN AFRICAN COAST
    Ostrich, 1992
    Co-Authors: J-j. Brossy
    Abstract:

    Summary Brossy, J-J. 1992. Malaria in wild and captive Jackass Penguins Spheniscus demersus along the southern African coast. Ostrich 63: 10–12. Avian malaria has been commonly reported in surveys of penguins of the genus Spheniscus, particular1 from American zoos. We have found similar infections in about 15% of penguins being kept at SANC-COB (South African Foundation for the Conservation of Coastal Birds). However we found only one doubtful positive identification of Plasmodium relictum in samples taken from over 140 wild birds, and conclude that it is rare in free-living Jackass Penguins in their natural habitat. Problems of prophylaxis in captive populations are discussed.

  • Selected ground-water data for Yucca Mountain region, southern Nevada and eastern California, through December 1996
    1997
    Co-Authors: R.j. Lacamera, G.l. Locke
    Abstract:

    The US Geological Survey, in support of the US Department of Energy, Yucca Mountain Site Characterization Project, collects, compiles, and summarizes hydrologic data in the Yucca Mountain region. The data are collected to allow assessments of ground-water resources during studies to determine the potential suitability of Yucca Mountain for storing high-level nuclear waste. Data on ground-water levels at 36 sites, ground-water discharge at 6 sites, and ground-water withdrawals within Crater Flat, Jackass Flats, Mercury Valley, and the Amargosa Desert are presented for calendar year 1996. Data collected prior to 1996 are graphically presented and data collected by other agencies (or as part of other programs) are included to further indicate variations of ground-water levels, discharges, and withdrawals through time. A statistical summary of ground-water levels at seven wells in Jackass Flats is presented to indicate potential effects of ground-water withdrawals in support of US Department of Energy activities near Yucca Mountain. The statistical summary includes the number of measurements, the maximum, minimum, and median water-level altitudes, and the average deviation of measured water-level altitudes for selected baseline periods and for calendar years 1992--96. At two water-supply wells and a nearby observation well, median water levels for calendar year 1996 were slightly lower (0.3 to 0.4 foot) than for the respective baseline periods. At four other wells in Jackass Flats, median water levels for 1996 were unchanged, slightly lower (0.2 foot), and slightly higher (0.2 and 0.7 foot) than for the respective baseline periods

  • Selected ground-water data for Yucca Mountain region, southern Nevada and eastern California, through December 1995

    Abstract:

    The US Geological Survey, in support of the U.S. Department of Energy, Yucca Mountain Site Characterization Project, collects, compiles, and summarizes hydrologic data in the Yucca Mountain region. The data are collected to allow assessments of ground-water resources during studies to determine the potential suitability of Yucca Mountain for storing high-level nuclear waste. Data on ground-water levels at 36 sites, ground-water discharge at 6 sites, and groundwater withdrawals within Crater Flat, Jackass Flats, Mercury Valley, and the Amargosa Desert are presented for calendar year 1995. Data collected prior to 1995 are graphically presented and data collected by other agencies (or as part of other programs) are included to further indicate variations of ground-water levels, discharges, and withdrawals through time. A statistical summary of ground-water levels at seven wells in Jackass Flats is presented to indicate potential effects of ground-water withdrawals in support of US Department of Energy activities near Yucca Mountain. The statistical summary includes the number of measurements, the maximum, minimum, and median water-level altitudes, and the average deviation of measured water-level altitudes for selected baseline periods and for calendar years 1992-95. Compared with baseline periods for the seven wells, median water levels for calendar year 1995 were slightly lower (0.1 to 0.2 foot) at two principal water-supply wells and one observation well nearest to those supply wells, slightly higher (0.2 to 0.5 foot) at three other wells in Jackass Flats, and unchanged at the seventh well

  • Seed dispersal potential of jackals and foxes in semi-arid habitats of South Africa
    Journal of Arid Environments, 2020
    Co-Authors: Jan F Kamler, Unn Klare, David W Macdonald
    Abstract:

    Abstract We determined the consumption of fruits and estimated potential seed dispersal of a canid community in semi-arid ecosystems of South Africa by comparing diets, defecation sites, densities and potential seed shadows of cape foxes (Vulpes chama), bat-eared foxes (Otocyon megalotis) and black-backed jackals (Canis mesomelas) on Benfontein and Rooipoort nature reserves. On Benfontein, all canid species consumed the fruit of Diospyros lycioides throughout the year. Jackals, but neither fox species, consumed relatively large amounts of Prosopis spp. (mesquite), an alien invasive. On Rooipoort, jackals had relatively high consumption of Ziziphus mucronata, followed by Grewia flava and D. lycioides. Bat-eared foxes had high consumption of fruit per area, although their seed dispersal potential was low due to their small potential seed shadow and poor germination sites. Cape foxes had the largest potential seed shadow, but their seed dispersal potential was low because of low fruit consumption, low density, and poor germination sites. Jackals had the highest seed dispersal potential because they consumed the most fruit species, had moderate densities, a relatively large potential seed shadow, and mostly good germination sites. We conclude that seed dispersal potential of South African canids, especially jackals, is more significant than previously known.

  • Lethal and sublethal effects of black-backed jackals on cape foxes and bat-eared foxes
    Journal of Mammalogy, 2013
    Co-Authors: Jan F Kamler, Ute Stenkewitz, David W Macdonald
    Abstract:

    Little is known about the sublethal effects of mesocarnivores on small carnivores, which can have important implications regarding the ecology and behavior of the latter. We investigated the ecology of cape foxes (Vulpes chama) and bat-eared foxes (Otocyon megalotis) in the absence of black-backed jackals (Canis mesomelas), a dominant mesocarnivore and predator of both fox species. Results were compared with a concurrent study that investigated the ecology of both fox species in the presence of jackals, at a site ,5 km away. In the absence of jackals, densities of cape foxes increased 64% despite similar food and habitat resources between sites, indicating that jackals suppressed cape fox populations. In contrast, jackals did not suppress populations of bateared foxes. For both fox species, the absence of jackals resulted in smaller home-range sizes and nonselective use of habitats for den sites, indicating that jackals had sublethal effects on the ecology and behavior of both fox species. Additionally, in the absence of jackals, cape foxes were marginally more active during daytime, whereas bat-eared foxes exhibited smaller group sizes. The 2 fox species became more segregated in the absence of jackals, indicating that jackals also had sublethal effects on the interspecific relationships of fox species. Our results showed that the effects of a mesocarnivore can extend well beyond population suppression of small carnivores, although sublethal effects varied in intensity and often were species specific. Sublethal effects on small carnivores can occur even if population suppression by a mesocarnivore is not occurring.

  • Resource partitioning among cape foxes, bat‐eared foxes, and black‐backed jackals in South Africa
    Journal of Wildlife Management, 2012
    Co-Authors: Jan F Kamler, Unn Klare, Ute Stenkewitz, Nicolas F. Jacobsen, David W Macdonald
    Abstract:

    Cape foxes (Vulpes chama) and bat-eared foxes (Otocyon megalotis) are sympatric with black-backed jackals (Canis mesomelas) over much of southern Africa, although competition with and/or predation by jackals may suppress local populations of both fox species. From 2005 to 2008, we captured, radio-collared, and monitored 11 cape foxes, 22 bat-eared foxes, and 15 black-backed jackals on a game ranch in South Africa to investigate their spatial, habitat, temporal, and dietary resource overlap. Mean annual home-range sizes were 27.7 km2 for cape foxes, 5.0 km2 for bat-eared foxes, and 17.8 km2 for jackal family groups. Home ranges overlapped completely between species, although core areas overlapped less (

  • Diet, Prey Selection, and Predation Impact of Black-Backed Jackals in South Africa
    Journal of Wildlife Management, 2010
    Co-Authors: Unn Klare, Jan F Kamler, Ute Stenkewitz, David W Macdonald
    Abstract:

    Abstract To investigate the role of black-backed jackals (Canis mesomelas) as predators, we studied diet, prey selection, and predation impact of jackals on 2 game ranches in South Africa that differed in ungulate diversity and biomass. Results showed that large (>15 kg) ungulate species dominated jackal diets throughout the year on both the less diverse (range of ingested biomass across seasons  =  39–78%) and more diverse (26–69%) game ranch. Other important food items included medium-sized mammals (1–3 kg; 1–26%) and fruit (2–69%), whereas small mammals comprised 3–11% of ingested biomass across seasons on both sites. Jackals were not random in consumption of ungulates, and consumption patterns suggested jackals actively hunted certain species rather than consumed them as carrion. During ungulate birthing periods, jackals consumed almost exclusively those ungulate species that were hiders (i.e., fawns were hidden in tall vegetation away from herd) regardless of ungulate densities, suggesting that prima...
