Improving compliance around protected areas through fair administration of rules.

Protected area management often depends heavily on law enforcement to secure compliance with rules. However, this can contribute to conflict between protected area authorities and local people, negatively affecting both human well-being and conservation outcomes. Compliance is affected by many factors, including whether those who enforce rules are perceived to do so fairly, as well as the perceived rule-related behavior of others. We used factorial survey experiments to explore how fair respondents living around protected areas in Indonesia and Tanzania perceive sanctions distributed by law enforcers to be. We presented scenarios to respondents to assess how crime type, offender characteristics, and corruption influenced their judgments regarding the fairness of administered sanctions. We also assessed how descriptive norms and corruption influenced individuals' willingness to obey protected area rules. Data were collected from 229 people in Indonesia and 217 in Tanzania. Results showed that in both locations, lawful sanctions, such as arrests or warnings, were perceived as fairer, and sanctions that involved corruption were perceived as least fair. Attitudes toward protected area rules, corruption, and descriptive norms all influenced people's willingness to comply, whereas multidimensional poverty did not. Our results highlight the need for conservation policy and practice to move beyond narratives that focus on the need for more law enforcement. To improve protected area compliance and secure better outcomes for people and nature, conservation must focus on ensuring the fair administration of rules and enhancing the legitimacy of rules themselves.

Mejoras en el cumplimiento alrededor de las áreas protegidas mediante la administración imparcial de reglas Resumen El manejo de áreas protegidas casi siempre depende de la aplicación de la ley para asegurar el cumplimiento de las reglas. Sin embargo, esto puede contribuir al conflicto entro las autoridades de las áreas protegidas y los locales, lo que afecta negativamente al bienestar humano y a los resultados de conservación. El cumplimiento se ve afectado por muchos factores, incluido si se percibe que quienes aplican las reglas lo hacen de manera imparcial, así como el comportamiento relacionado a las reglas de las demás. Aplicamos experimentos de censo factorial para explorar cómo los respondientes imparciales que viven en torno a las áreas protegidas en Indonesia y Tanzania perciben las sanciones distribuidas por los agentes de la ley. Les presentamos escenarios para analizar cómo el tipo de crimen, características del ofensor y la corrupción influyen sobre sus juicios con respecto a la imparcialidad de las sanciones administradas. También analizamos cómo las normas descriptivas y la corrupción influyen sobre la voluntad individual de obedecer las reglas del área protegida. Recolectamos los datos de 299 personas en Indonesia y 217 en Tanzania. Los resultados mostraron que, en ambas localidades, las sanciones legales, como arrestos o advertencias, eran percibidas como más justas, y las sanciones que involucraban corrupción eran percibidas como las menos justas. Todas las actitudes hacia las reglas de las áreas protegidas, la corrupción y las normas descriptivas influyeron sobre la voluntad de las personas para obedecer, mientras que la pobreza multidimensional no influyó. Nuestros resultados enfatizan la necesidad de que las políticas y prácticas de conservación vayan más allá de las narrativas que se enfocan en la necesidad de una mayor aplicación de la ley. Para incrementar el cumplimiento en las áreas protegidas y asegurar mejores resultados para las personas y la naturaleza, la conservación debe enfocarse en garantizar la administración imparcial de las reglas e incrementar su legitimidad.

A mixed methods approach for measuring topic sensitivity in conservation.

Conservationists increasingly aim to understand human behaviour to inform intervention design. However, obtaining information from people about their behaviour can be challenging, particularly if the research topic is considered sensitive. Topic sensitivity may raise methodological, ethical, political and legal concerns which, if poorly addressed, can have significant impacts on research participants, the research process, data quality and the success of conservation outcomes that are informed by research findings. While considerable effort has been invested in developing techniques for reducing bias when collecting data on sensitive topics, less attention has been focused on identifying if, and why, a topic is sensitive.We use a mixed methods approach to explore how willing people are to discuss topics that could be considered sensitive (e.g. illegal wildlife hunting). Collecting data from people living near protected areas in Indonesia (n = 362) and Tanzania (n = 345), we developed and tested a psychometric scale to measure topic sensitivity at the respondent level and conducted group exercises (free-lists and pile sorts) to gain a deeper understanding of peoples' willingness to discuss different topics.The perceived sensitivity of topics varied both within and between the two focal contexts, with more topics being perceived as sensitive in Tanzania than Indonesia. Participants' knowledge of rules, and their experiences of living alongside protected areas affected how sensitive they considered topics to be.Mixed methods approaches can provide holistic and nuanced understanding of topic sensitivity. However, recognising that in-depth studies are not always feasible to implement, we demonstrate that methods, such as our Sensitivity Index, can easily be adapted for different contexts and deployed to rapidly obtain valuable insights on topic sensitivity, to help inform conservation research and practice.

Experimental validation of specialized questioning techniques in conservation.

Conservation increasingly relies on social science tools to understand human behavior. Specialized questioning techniques (SQTs) are a suite of methods designed to reduce bias in social surveys and are widely used to collect data on sensitive topics, including compliance with conservation rules. Most SQTs have been developed in Western, industrialized, educated, rich, and democratic countries, meaning their suitability in other contexts may be limited. Whether these techniques perform better than conventional direct questioning is important for those considering their use. We designed an experiment to validate the performance of four SQTs (unmatched count technique, randomized response technique, crosswise model, and bean method) against direct questions when asking about a commonly researched sensitive behavior in conservation, wildlife hunting. We developed fictional characters, and for each method asked respondents to report the answers that each fictional character should give when asked if they hunt wildlife. We collected data from 609 individuals living close to protected areas in two different cultural and socioeconomic contexts (Indonesia and Tanzania) to quantify the extent to which respondents understood and followed SQT instructions and to explore the sociodemographic factors that influenced a correct response. Data were modeled using binomial general linear mixed models. Participants were more likely to refuse to answer questions asked using SQTs compared with direct questions. Model results suggested that SQTs were harder for participants to understand. Demographic factors (e.g., age and education level) significantly influenced response accuracy. When sensitive responses to sensitive questions were required, all SQTs (excluding the bean method) outperformed direct questions, demonstrating that SQTs can successfully reduce sensitivity bias. However, when reviewing each method, most respondents (59-89%) reported they would feel uncomfortable using them to provide information on their own hunting behavior, highlighting the considerable challenge of encouraging truthful reporting on sensitive topics. Our results demonstrate the importance of assessing the suitability of social science methods prior to their implementation in conservation contexts.

Validación Experimental de las Técnicas de Cuestionamiento Especializado en la Conservación Resumen La conservación depende cada vez más de herramientas de las ciencias sociales para entender el comportamiento humano. Las técnicas de cuestionamiento especializado (TCE) son un conjunto de métodos diseñados para reducir el sesgo en los censos sociales y y se usan ampliamente para recolectar datos sobre temas sensibles, incluyendo el cumplimiento de las normas de conservación. La mayoría de las TCE se desarrollaron en el hemisferio occidental, en países industrializados, educados, ricos y democráticos, lo que significa que su que su idoneidad en otros contextos puede ser limitada. Quienes piensan en usar estas técnicas consideran importante saber si tienen un mejor desempeño que el cuestionamiento directo convencional. Diseñamos un experimento para validar el desempeño de cuatro TCE (técnica de conteo sin par, técnica de respuesta aleatoria, modelo transversal, método bean) frente a las preguntas directas cuando se cuestiona sobre un comportamiento sensible de interés recurrente en la conservación: la cacería de fauna. Desarrollamos personajes ficticios y para cada método le pedimos a los respondientes que reportaran las respuestas que cada personaje ficticio debería dar al cuestionársele si cazan fauna silvestre. Recolectamos datos de 609 individuos con residencia cercana a áreas protegidas en dos contextos cultural y socioeconómicamente diferentes (Indonesia y Tanzanía) para cuantificar el grado al que los respondientes entendieron y siguieron las instrucciones de las TCE y para explorar los factores sociodemográficos que influyeron sobre las respuestas correctas. Modelamos los datos mediante modelos lineales mixtos binomiales y generales. Fue más probable que los participantes se rehusaran a responder las preguntas realizadas con las TCE en comparación con las preguntas directas. Los resultados del modelo sugirieron que las TCE eran más difíciles de entender para los participantes. Los factores demográficos (p. ej.: edad y nivel educativo) influyeron significativamente la certeza de las respuestas. Cuando se requirieron respuestas sensibles a preguntas sensibles, todas las TCE (excepto el método bean) tuvieron un mejor desempeño que las preguntas directas, lo que demuestra que las TCE pueden reducir exitosamente el sesgo por sensibilidad. Sin embargo, cuando se les preguntó sobre cada método, la mayoría de los respondientes (59-89%) reportó que se sentirían incómodos si tuvieran que usarlas para proporcionar información sobre sus propios comportamientos de cacería, lo que destaca el reto considerable que es reportar honestamente los temas sensibles. Nuestros resultados demuestran la importancia de de evaluar la idoneidad de los métodos de las ciencias sociales previo a su implementación en contextos de conservación.

Changes in the human footprint in and around Indonesia's terrestrial national parks between 2012 and 2017.

The human footprint (HF) was developed to measure of the impact of human activities on the environment. The human footprint has been found to be closely related to the vulnerability of protected areas around the world. In Indonesia, as nature conservation is still seen as hindering economic development, it is especially important to assess the human footprint in order to comprehend the overall pressures resulting from the various human activities on Indonesia's national parks. This study measured the change in the human footprint in and around 43 terrestrial national parks over 5 years, between 2012 and 2017. As many as 37 out of 43 NPs experienced an increase in the HF, ranging from 0.4 to 77.3%. Tanjung Puting in Kalimantan experienced the greatest increase (77.3%), while Ujung Kulon in Jawa Bali bioregion had the greatest decrease (10.5%). An increase in human population density and improved access to parks from roads, rivers and coastlines are the main drivers of increasing impacts on national parks.

Psychoactive substances use and associated factors among middle and high school students in the North Center of Morocco: a cross-sectional questionnaire survey.

BACKGROUND: Data on psychoactive substance (PAS) consumption among adolescents in the North Center of Morocco are not at all available. Therefore, the current study aimed at investigating the prevalence and the determinants of psychoactive substances use among middle and high school students in this region. METHODS: A cross-sectional study was conducted from April 2012 to November 2013 in public middle and high schools in the North Central Region of Morocco. An anonymous self-administered questionnaire was used to assess psychoactive substances use among a representative sample of school students from the 7th to the 12th grade, aged 11-23 years, selected by stratified cluster random sampling. Factors associated with psychoactive substance use were identified using multivariate stepwise logistic regression analyses. RESULTS: A total of 3020 school students completed the questionnaires, 53.0 % of which were males. The overall lifetime smoking prevalence was 16.1 %. The lifetime, annual and past month rates of any psychoactive substance use among the study subjects were 9.3, 7.5, and 6.3 % respectively. Cannabis recorded the highest lifetime prevalence of 8.1 %, followed by alcohol 4.3 %, inhalants 1.7 %, psychotropic substances without medical prescription 1.0, cocaine 0.7, heroine 0.3, and amphetamine with only 0.2 %. Psychoactive substance use was associated with males more than females. The risk factors identified by multivariate stepwise logistic regression analyses were being male, studying in secondary school level, smoking tobacco, living with a family member who uses tobacco, and feeling insecure within the family. CONCLUSIONS: The prevalence among all school students reported by the current study was comparable to the national prevalence. Efforts to initiate psychoactive substance prevention programs among school students should be made by designing such programs based on the significant factors associated with psychoactive substance use identified in this study.

[Cryptococcal meningitis in a patient with a ventriculoperitoneal shunt and monitoring for pulmonary sarcoidosis]. / Cryptococcose neuroméningée chez un patient porteur d'une valve de dérivation ventriculo-péritonéale suivi pour sarcoïdose pulmonaire.

The fungus Cryptococcus neoformans can cause common opportunistic infection in acquired immune deficiency syndrome (AIDS) patients. But other conditions can be associated with sarcoidosis. Meningoencephalitis is the most common manifestation of this disease. One of the most important neurological complications is the development of intracranial hypertension (ICH), which may result in high morbidity and mortality. We report the case of a patient harboring a ventriculoperitoneal shunt, and having contracted a cryptococcal meningitis as a risk factor for pulmonary sarcoidosis. Brain MRI showed arachnoiditis, with a mass in contact with the right frontal horn. Indian ink staining of the cerebrospinal fluid (CSF) showed positivity that was confirmed by the identification of Cryptococcus neoformans after culture. The evolution was favorable under medical treatment with removal of material. The relationship between sarcoidosis and cryptococcosis, described in the literature is not coincidental but is a rare complication of sarcoidosis of potential severity (40% of mortality). Sarcoidosis is a common systemic disease that may increase host susceptibility to CNS cryptococcal infection without any other signs or symptoms of host immunosuppression. The diagnosis of cryptococcosis should be evoked as a differential diagnosis of neuro-sarcoidosis.

[Neuroepithelial thalamo-mesencephalic cyst]. / Kyste neuroépithélial thalamo-mésencéphalique.

Thalamo-mesencephalic neuroepithelial cysts are rare lesions of the central nervous system. They are thought to arise from neuroectoderm and are also referred to as ependymal cysts due to their origin. It can remain asymptomatic throughout life or rarely can cause symptoms. We describe a 42-year-old woman who presented with thalamic syndrome due to a neuroepithelial cyst of the thalamo-midbrain. Differential diagnosis is made with other cystic lesions in the brain. However a good analysis of imaging feature led to diagnosis. When the lesion is symptomatic, mini-invasive procedure is indicated.

[Spheno-orbital mesenchymal chondrosarcoma. A case report]. / Chondrosarcome mésenchymateux sphéno-orbitaire. A propos d'un cas.

Mesenchymal chondrosarcoma is a highly malignant and extremely rare tumor of the orbit: only 18 cases have been reported to date. We report a case of spheno-orbital mesenchymal chondrosarcoma in a 36-year-old woman presented with a 4-month history of progressive left exophthalmia and temporal mass. A CT-scan of the orbit and MRI showed a spheno-orbital mass, with temporal fossa extension, fed by the internal maxillary artery visible on cerebral angiography. Surgery via a transcranial, left frontotemporozygomatic approach after selective embolization enabled subtotal removal. Definitive histologic examination revealed mesenchymal chondrosarcoma. Postoperatively, exophthalmia spectacularly regressed. We report our clinical findings and present a review of the literature.

[Takayasu's disease in Morocco. Report of 47 cases]. / La maladie de Takayasu au Maroc. A propos de 47 observations.

PURPOSE: Takayasu's disease is a chronic inflammatory arteritis involving large vessels in young women. We studied Moroccan patients to evaluate clinical, biological, radiological and evolution features of this disease in our country. METHODS: Forty-seven patients with Takayasu's arteritis were studied retrospectively between 1988 et 1999. RESULTS: In our series involvement of the aortic arch and its branches was more frequent than the abdominal aorta and its branches. Stenotic lesions of renal arteries were rare. Ultrasound was useful in the diagnosis and the monitoring of the disease. Treatment with glucocorticoids gave good results, with improvement in half of the patients and remission with stabilisation in 40% of cases. Tuberculosis occurred in 8.5% of patients. CONCLUSION: The use of ultrasound and computed tomography angiography is helpful for the diagnosis and monitoring of the disease progression. Glucocorticoids help to induce long remission in about 80% of treated patients. We don't find any relationship between Takayasu's arteritis and tuberculosis.

Effect of dialysis or centrifugation on post-thaw motility and fertility of Santa Gertrudis bull semen collected by electroejaculation.

Electroejaculated semen from Santa Gertrudis bulls was used to study the effect of centrifugation (600 x g for 5 min) or dialysis [molecular weight cutoff <14,000 Daltons (Da)] on post-thaw motility and on fertility in beef cattle. Analysis of post-thaw motility showed that the main effects (bulls and semen treatment) were significant (P<0.05). Dialysis significantly improved post-thaw motility in four of seven bulls. Initial volume of seminal plasma in the ejaculate was negatively correlated to post-thaw motility (r = -0.73). No significant improvement in post-thaw motility was observed for bulls with high volumes of ejaculate. In a fertility trial, calving rates of heifers synchronized with PGF(2)alpha and inseminated at 72 and 96 h after the second PGF(2)alpha injection with dialyzed or commercial semen were not statistically different (P>0.05; 54.4% vs 55.4%). These results show that dialysis could be used to improve post-thaw motility of electroejaculated bull semen without altering its fertilizing capacity. However, a high initial volume of seminal plasma seems to have a deleterious effect on sperm freezability that cannot be reversed by dialysis.
