Camera trapping is increasingly recognised as a survey tool akin to conventional small mammal survey methods such as Elliott trapping. While there are many cost and resource advantages of using camera traps, their adoption should not compromise scientific rigour. Rodents are a common element of most small mammal surveys. In 2010 we deployed camera traps to measure whether the endangered Hastings River mouse (Pseudomys oralis) could be detected and identified with an acceptable level of precision by camera traps when similar-looking sympatric small mammals were present. A comparison of three camera trap models revealed that camera traps can detect a wide range of small mammals, although white flash colour photography was necessary to capture characteristic features of morphology. However, the accurate identification of some small mammals, including P. oralis, was problematic; we conclude therefore that camera traps alone are not appropriate for P. oralis surveys, even though they might at times successfully detect them. We discuss the need for refinement of the methodology, further testing of camera trap technology, and the development of computer-assisted techniques to overcome problems associated with accurate species identification.

The World

Context The adoption of camera trapping in place of traditional wildlife survey methods has become common despite inherent flaws in equipment and a dearth of research to test their fit for purpose. Overwhelmingly, the development of commercial camera traps has been driven by the needs of North American hunters. Camera-trap models and features are influenced by these market forces that drive the changes in designs as new technologies develop. This focus on recreation, rather than research has often frustrated wildlife professionals as the equipment has rarely met minimum standards for scientific application. Aims We investigated the demand for white-flash camera traps around the world to highlight the demand for such camera traps in wildlife research to the manufacturing industry. We also compiled the camera-trap specifications required by scientists through the world in an effort to influence and improve the quality of camera traps for research. Methods We carried out an internet-based survey of biologists, zoologists, conservationists and other wildlife researchers by using a questionnaire to gather baseline market data on camera-trap use and demand. We also conducted an informal survey of scientists via email and in person, asking for their preferences and features of an ultimate camera-trap design. Key result Infrared camera traps are widely used and more so than white-flash camera traps, although the demand for white flash remains significant. Cost, speed, size, ease of use, versatility and the range of settings were the key features identified in a good camera trap. Conclusions The present paper describes and discusses the desired features and specifications as defined by over 150 scientists using camera traps around the world. Data gathered also provide some insight into the market demand for camera traps by biologists, zoologists, conservationists and other wildlife researchers around the world. These design features are discussed under the guise of the ultimate camera trap for wildlife research, with the disclaimer that no such camera trap currently exists. Implications The information provided in the paper has and will be a useful guide to future camera-trap designs, although it is unlikely that all of the features required will ever be produced in a cheap camera trap.

Abstract Traditional transect survey methods for forest antelopes often underestimate density for common species and do not provide sufficient data for rarer species. The use of camera trapping as a survey tool for medium and large terrestrial mammals has become increasingly common, especially in forest habitats. Here, we applied the distance sampling method to images generated from camera-trap surveys in Dja Faunal Reserve, Cameroon, and used an estimate of the proportion of time animals are active to correct for negative bias in the density estimates from the 24-hour camera-trap survey datasets. We also used multiple covariate distance sampling with body weight as a covariate to estimate detection probabilities and densities of rarer species. These methods provide an effective tool for monitoring the status of individual species or a community of forest antelope species, information urgently needed for conservation planning and action.

Although ego-centered network data provide information that is limited in various ways as compared with full network data, an ego-centered design can be used without the need for a priori and researcher-defined network borders. Moreover, ego-centered network data can be obtained with traditional survey methods. However, due to the dynamic structure of the questionnaires involved, a great effort is required on the part of either respondents (with self-administration) or interviewers (with face-to-face interviews). As an alternative, we will show the advantages of using CASI (computer-assisted self-administered interview) methods for the collection of ego-centered network data as applied in a study on the role of social networks in substance use among college students.

Abstract This study aims to empirically challenge the moderation of Non-Performing Loans to the effect of Credit Distribution Rates on Profitability. The population of 81 bank companies listed on the Indonesia Stock Exchange in the period 2014-2018 and which met the criteria of the research sample (purposive sampling) were 22 companies. The research method uses survey methods with quantitative research approaches, the analytical tool used is moderation regression. This study concludes that the level of credit distribution has a significant positive effect on profitability and the existence of the problem loan variable is proven to be a moderating variable that weakens the relationship between the level of credit distribution and profitability.

Competency Level

Intensity to produce a quality human capital is not sufficient by having basic skills for certain field only. The need to have a competitive attitude to enhance their level of competency is much concern for many employers nowadays. Hence, this study is conducted to identify the competitiveness factors that influence the level of competency among graduates, especially who employed in the service sector in Malaysia. This study used survey methods by distributing questionnaires for data collection. The study used stratified purposive sampling by distributing a questionnaire to 450 graduates from 13 services sectors based on a statistic from the Ministry of Higher Education 2016. The finding from the exploratory factor analysis found that seven competitiveness factors were consisting of 47 items that form the competitiveness attitude among graduates. However, based on multiple linear regression analysis, only five models of competitiveness factors have a significant relationship with graduates’ competency which are job competitiveness, organizational management competitiveness, dominant competitiveness, goal competitiveness and self-improvement competitiveness. In fact, aggressive competitiveness and general competitiveness does not influence graduates’ competency level significantly. Thus, the more competitive attitude of graduates such as emotional control, innovation, and competitiveness to be the best is vital for their future marketability. In addition, it is hoped that their level of competence can be enhanced through the development of competitive factors for the advancement of the country's higher education talent.
