Knowledge on the impacts of logging activity on inhabitant primate species in Kwabre Rainforest, Ghana, is vital for the development of a comprehensive conservation and management plan. With this background, primate density and diversity were recorded along line transects in logged and unlogged areas (strata) to assess the impact of logging activity on these parameters. Six distinct primate species were confirmed including Roloway monkey (Cercopithecus roloway, listed as endangered in the IUCN List of Threatened Species), white-naped mangabey (Cercocebus lunulatus, vulnerable), and Geoffroy’s black-and-white colobus (Colobus vellerosus, vulnerable). There was a significant difference (Mann-WhitneyUtest:U=36.0,p<0.01) in primate encounter rates between the logged and unlogged strata with higher species diversity in unlogged stratum (H=2.91) compared to the logged stratum (H=1.44). Regression analysis indicated a significant effect (r2=0.945,p<0.01) of logging on primate encounter rates. Our results suggest that logging activity can alter composition of primate communities. One option to forestall further forest degradation and its adverse effects on primates would be to grant the Kwabre Rainforest protected area status under Ghanaian law and manage it under an integrated conservation plan that includes neighbouring Ankasa Conservation Area in Ghana and Tanoé Forest in Cote d’Ivoire.

<p>The status of Lowe’s Monkey <em>Cercopithecus lowei</em> was assessed during a survey in Kakum Conservation Area, Ghana.  Within the reserve logging and hunting was banned 20 years ago, and the forest underwent two decades of natural regeneration.  The main objectives of the study were to evaluate the impact of conservation measures on the local population of Lowe’s Monkey<em> </em>and assess its relationships with other primates and non-primate mammals.  Data on population status were collected during line transect surveys.  Comparing the present mean encounter rate of 1.03 (±0.03) groups/km to that recorded in 1993 (0.31±0.16 groups/km) suggests an average population growth rate of 13.6% per annum.  Conservation measures such as banning illegal logging and hunting have likely contributed to the population increase.  Lowe’s monkeys were often observed in close proximity to other primates (e.g., Black and White Colobus) and non-primate mammals (e.g., Maxwell’s Duiker), but neither socio-positive nor antagonistic interactions were observed.  Recommendations are made for further improvement and studies of the species elsewhere.</p><div> </div>

AbstractThe contexts and functions of several loud mangabey vocalizations, particularly the "whoopgobble", were investigated observationally and experimentally. Whoopgobbles are notable for their audibility and distinctiveness over long distances, their temporal pattern of delivery, and particularly their stereotypy and individual distinctiveness. On the other hand, contexts of and responses to these vocalizations are variable and sometimes nonobvious. In order to control context and more systematically investigate response, an experimental method involving playback of recorded vocalizations was developed. Although precautions against habituation were necessary, mangabey responses to playbacks were clearcut and repeatable. Answering vocalizations, changes in group movement, and changes in the dispersion of individuals within a group occurred only in response to mangabey vocalizations. Whoopgobble playbacks provoked a pattern of response, including most notably the rapid approach of one adult male (the "RA" male) from each group, which was specific to this call. Playback of whoopgobbles between 100 and 600m from mangabey groups indicated that this call does transmit information regarding the identity of the vocalizing individual and group over these distances. Test groups moved away from neighboring- and unknown-group calls, but towards those of their own males - particularly those of RA males. RA males, on the other hand, do not approach calls of other males from their own groups. Within a group, whoopgobbles may thus increase cohesion and influence the direction of movements. Characteristics of whoopgobble form and context are discussed with regard to hypothesized functions of these and other forest monkey loud calls. Responses by free-ranging mangabeys to playback of the whoopgobble confirm its role in maintaining distance between groups. Response was found to be independent of group size, despite the fact that whoopgobble rate is closely related to this variable and thus could transmit such information. Since responses were also found to be independent of location within the home range, intergroup spacing among mangabeys appears not be be "territorial", site defense does not occur. Nevertheless, the central areas in at least some mangabey groups' home ranges were never penetrated by neighbors. Playback tests with black-and-white colobus and blue monkeys, among which territorial spacing has been reported, indicate that responses to loud calls have some degree of site-specificity among these species. But the mangabey pattern of intergroup spacing appears to result from a combination of low group density, site attachment within groups, and site-independent avoidance between groups. These results emphasize that spacing "system" and "pattern" are not necessarily equivalent; a given set of spacing behaviors can result in different spacing patterns under different ecological conditions, while a given pattern may be obtained by any of several behavioral means. Evidence for site-independent spacing in other primate species is discussed.

PurposeThe purpose of this research is to compare the fatality rate of Black and White subjects shot by police. This comparison is meant to explore whether officer-involved shootings (OIS) are impacted more by perceived threat or by demographic characteristics. Beyond race, contextual and officer-level variables are examined for their influence on lethal vs non-lethal police shootings.Design/methodology/approachThe study utilizes data from the Tampa Bay Times database on police shootings in Florida from 2009 through 2014. Our analysis focuses on the substantive importance of this issue, using the population of OIS in one specific state over a specified time period. The authors also including multinomial logistic regression models analyzing the impact of race, contextual and officer-level variables on the lethal outcome of OIS is clear that the police are shooting at two very different populations.FindingsAlthough Black subjects are disproportionately represented as the subjects of OIS, there was no significant difference in the lethality of such incidents based simply on race. However, when we compare Black subjects to White subjects, it is clear that the police are shooting at two very different populations. Black subjects were younger, less likely to be armed, less likely to be under the influence of drugs or alcohol, and less likely to have suspected or known mental health considerations than their White counterparts.Research limitations/implicationsThus, it is possible that any racialized difference in the lethality of police shootings is being suppressed because we are comparing very different groups of subjects to one another.Originality/valueThis paper is the first to examine the racial threat that officers experience past the decision to engage in violence. The authors are looking at how they shoot at minorities vs the decision to shoot at minorities.

Minerals are vital for many metabolic processes, and mineral deficiencies can adversely impact health and fitness. Mineral concentrations of food items are commonly reported in primate nutritional ecology studies and have been identified as important factors in primate food selection; however, very few studies have quantified daily mineral intake of free-ranging primates. We examined the concentration of 9 minerals (Ca, P, Mg, K, Na, Fe, Zn, Cu, and Mn) in foods consumed by <i>Colobus angolensis palliatus</i> inhabiting the Diani Forest of Kenya, and test whether individuals preferentially selected leaves in accordance with their mineral concentrations. We also examined the effects of sex, group, and season on daily mineral intake, quantifying both percentage-based and mass-based intakes. We then compared daily mineral intake values to published recommendations. Behavioral data and plant samples were collected from July 2014 to December 2015. We found that individuals preferred leaves with greater P content and lower Ca content. Daily mineral intake differed significantly between sexes and among groups and seasons. These results are interpretable via differences in time spent feeding and total energy intake. Intakes fell below percentage-based recommendations for P, Na, Fe, Cu, and Mn but met or exceeded mass-based recommendations for all minerals except Na. This discrepancy is likely explained by the conservative nature of percentage-based mineral recommendations and the difficulty of comparing and scaling mass-based mineral recommendations among primate species. Studies that quantify daily mineral intake are needed to better understand the role of minerals on dietary selection, more accurately identify potential mineral deficiencies, and provide more informed recommendations for captive primates.

Abstract. Husodo T, Shanida SS, Megantara EN. 2019. Biodiversity management plan in the non-conservation area, Cisokan hydropower plan area, Cianjur, West Java, Indonesia. Biodiversitas 20: 1524-1536. Based on data from various environmental studies at the Upper Cisokan Pumped Storage (UCPS) Hydropower plan area, further studies need to be carried out that can provide clearer guidance on how to protect and restore the environment (including habitat) around the UCPS, protect, and manage the endangered biodiversity through adaptive approaches and ecosystem management. One of these studies was the UCPS Biodiversity Management Plan (BMP). The aim of this study was to identify the strategy for biodiversity management at the project site. Methods of this study were based on several years of qualitative and descriptive-analytical studies, which updated information from earlier studies. Information on the area’s biodiversity was obtained directly through field surveys and indirectly through semi-structured interviews and focus group discussions (FGD) with local community members and other stakeholders in the area. This article presents the strategy for biodiversity management at project site, including minimizing habitat gap and habitat loss; expanding and enriching habitats; making corridors; protecting the natural forests (protection of remnant forest); controlling access; managing fire, the impact of traffic on native fauna, land clearing and human-wildlife conflict; minimizing impacts to biodiversity,  particularly threatened species; integrating management with adjoining land managers (PLN, perhutani, the community); strengthening capacities for integrating and institutionalizing biodiversity conservation and management; conducting campaign for biodiversity awareness, communication, and education; and developing value-added products and alternative sustainable livelihood for bio-resource-dependent communities.

AbstractDuring the last two decades the archipelago of Svalbard has evolved as a focal point for tourism and scientific research in the Arctic. In 1995 the Norwegian authorities inaugurated a management plan in order to conserve Svalbard and to minimise environmental degradation resulting from increased anthropogenic activity. However, the potential for accelerated modification of the tundra, as a result of field camps, was not addressed. Parameters, such as percentage vegetation cover, soil compaction, and soil infiltration rate were measured before and after a four-week period of field-camp activity, under controlled conditions, during July 1997. The study site was located near Ny-Ålesund, Kongsfjorden, Spitsbergen. Statistical analysis showed that where no significant differences in the parameters were recorded at the control site, the presence of a field camp did cause a significant impact on the Arctic heath tundra surface. For example, mean soil compaction, increased from 1.16 kg cm-2 to 2.57 kg cm-2. The use of good practice procedures, such as moving tents regularly and utilising a groundsheet, did not prevent an impact on the environment. Key parameters at the main study sites were reassessed in July 1999, revealing that no significant recovery from the impact caused in 1997 had occurred. An established campsite at Ny-Ålesund was also studied in 1997, and the results support the findings of the main survey: a significant difference recorded for the parameters measured at the campsite, compared to negligible or no changes at the control site. In order to achieve a sustainable tourism and science-based community in Svalbard, i t is proposed that the existing management plan be expanded to incorporate a set of guidelines for wilderness camping, with the aim of mitigating the impact of field camps on the tundra.

Stress in caregivers may affect the healthcare recipients receive. We examined the impact of stress experienced by 45 adult caregivers of their elderly demented parents. The participants completed a 32-item questionnaire about the impact of experienced stress. The questionnaire also asked about interventions that might help to reduce the impact of stress. After exploratory factor analysis, we reduced the 32-item questionnaire to 13 items. Results indicated that caregivers experienced stress, anxiety, and sadness. Also, emotional, but not financial or professional, well-being was significantly impacted. There was no significant difference between the impact of caregiver stress on members from the sandwich generation and those from the nonsandwich generation. Meeting with a social worker for resource availability was identified most frequently as a potentially helpful intervention for coping with the impact of stress.

This exploratory study examined the impact of implicit and explicit oral corrective feedback (CF) on the development of implicit and explicit knowledge of Japanese locative particles (activity de, movement ni and location ni) for those who directly received CF and those who observed CF in the classroom. Thirty-six college students in a beginning Japanese language course received either recast (implicit), metalinguistic (explicit) or no feedback during an information-gap picture description activity, and completed a timed picture description test (implicit knowledge) and an untimed grammaticality judgement test (explicit knowledge) in a pre-test, immediate post-test and delayed post-test. The results showed that overall there was no significant difference between CF types, and that CF benefited direct and indirect recipients similarly. Potential factors that might influence the effectiveness of CF, such as instructional settings, complexity of target structures and pedagogy styles, are discussed.

Scientific research into the reduction of stigmatization, particularly related to specific problems such as Obsessive-Compulsive Disorder (OCD), is scarce. In the present study, we examine the impact of a video-based antistigma intervention program for OCD in a pretest-posttest control group research. After being randomly assigned to either an intervention (n= 101) or control group (n= 96), the participants reported their attitudes on a hypothetical case vignette before and after OCD vs. Multiple Sclerosis (MS) videos, and again six months later as a follow up assessment. The mixed design analyses for the group comparisons indicated that although there was no significant difference in the measures of the control group, the participants watching the anti-stigma OCD video, in which the focus was psychoeducation and interaction strategies, reported significantly lower scores on social distances and negative beliefs for the case vignettes they read, and this difference was maintained six months later. Then, the present results indicate the effectiveness of our anti-stigma intervention program for OCD. Interventions to reduce stigmatization can also be viewed as effective tools for changing the attitudes of people toward OCD, although further research and applications are needed related to specific disorders if a longlasting impact is to be achieved.

Quality of work life is the major factor to be considered in working environment of any organization. The performance of employees and the organization lies on the ability of the employees based on working environment. The QWL leads to better working environment which improves the performance of organization. The present study has made an attempt to find the level of factors causing QWL and the impact of outcome of QWL in banks. Since the profile of the banks may be associated with the level of outcomes of QWL, the present study has made an attempt to examine it with the help of one way analysis of variance and t-test. The included outcomes of QWL are job satisfaction, job stress, organizational climate, organizational commitment, employees retention behaviour, service quality employees and service productivity of employees. The highly associated determinants of QWL and the significant difference among the PUSBs and PRSBs have been noticed. The significantly associating important profiles of the banks regarding the existence of outcome of QWL are identified.
