Colour preference, naturalness, vividness and colour quality metrics, Part 4: Experiments with still life arrangements at different correlated colour temperatures
Authors: Khanh TQ , Bodrogi P , Vinh QT , Guo X , Anh TT
Published: March 2017

Subjective colour preference, naturalness and vividness assessments of two different colourful still life arrangements viewed in a real room were analysed and modelled with the aid of the Rf colour fidelity metric combined with a chroma difference metric. Coloured objects were illuminated by a four-channel LED light engine with 36 different spectra at four correlated colour temperatures and nine object oversaturation levels. Results imply a significant dependence of the subjective judgments on correlated colour temperature.

Published: March 2017

This article describes the process and results associated with the organizational-level recruitment of Black barbershops into Fitness in the Shop (FITShop), a 6-month barbershop-based intervention study designed to promote physical activity among Black men. Organizational-level recruitment activities included (1) a telephone call to prospective barbershop owners to assess their interest and eligibility for participation, (2) an organizational eligibility letter sent to all interested and eligible barbershops, (3) a visit to interested and eligible barbershops, where a culturally sensitive informational video was shown to barbershop owners to describe the study activities and share testimonies from trusted community stakeholders, and (4) a signed agreement with barbershop owners and barbers, which formalized the organizational partnership. Structured interviews were conducted with owners of a total of 14 enrolled barbershops, representing 30% of those determined to be eligible and interested. Most enrolled shops were located in urban settings and strip malls. Barbershop owners were motivated to enroll in the study based on commitment to their community, perceived client benefits, personal interest in physical activity, and a perception that the study had potential to make a positive impact on the barbershop and on reducing health disparities. Results offer important insights about recruiting barbershops into intervention trials.

Published: March 2017

Purpose: To report a single-center study comparing drug-coated balloon (DCB) angioplasty vs directional atherectomy with antirestenotic therapy (DAART) for isolated lesions of the popliteal artery. Methods: Seventy-two patients were treated with either DCB angioplasty alone (n=31) or with DAART (n=41) for isolated popliteal artery stenotic disease between October 2009 and December 2015. The majority of patients presented with lifestyle-limiting claudication (74% vs 86%, respectively). Vessel calcification (29% vs 29%, respectively), mean lesion length (47 vs 42 mm, respectively), and number of runoff vessels were comparable between the groups. The primary outcome measure was primary patency; secondary outcomes were technical success (<30% residual stenosis or bailout stenting), secondary patency, and freedom from clinically driven target lesion revascularization (TLR). Results: The technical success rate following DCB was 84% vs 93% (p=0.24) after DAART. The 12-month primary patency rate was significantly higher in the DAART group (65% vs 82%; hazard ratio 2.64, 95% confidence interval 1.09 to 6.37, p=0.021), while freedom from TLR did not differ between the 2 treatment strategies (82% vs 94%, p=0.072). Secondary patency at 12 months was identical for both groups (96% vs 96%). Although not statistically significant, bailout stenting was more common after DCB angioplasty (16% vs 5% for DAART, p=0.13) and aneurysmal degeneration of the popliteal artery was seen more often after DAART (7% vs 0% for DCB alone, p=0.25). Popliteal artery injury was observed in 2 patients treated using DAART (5% vs 0% for DCB alone, p=0.5), whereas distal embolization rates were comparable between the groups (3% for DCB alone vs 5% for DAART, p=0.99). Conclusion: In this study, the use of DAART was associated with a higher primary patency rate compared with DCB angioplasty for isolated popliteal lesions. Nonetheless, both treatment options were associated with excellent 12-month secondary patency. Aneurysmal degeneration of the popliteal artery and increased bailout stenting could compromise the outcomes of DAART and DCB, respectively.

Published: March 2017

Although the majority recovers from the death of a loved one, nearly 5% exhibit persistent symptoms of grief, known as Persistent Complex Bereavement Disorder (PCBD). PCBD has adverse health, social, and psychological consequences. We examined the effectiveness of dialectical behavior therapy (DBT) skills training with a 57-year-old African American woman who met the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) criteria for PCBD and Persistent Depressive Disorder. The client met with a graduate student therapist (i.e., the second author) who applied DBT skills training on an individual basis. By the end of treatment, the participant no longer met the criteria for either of these disorders. Reliable and clinically significant reduction in her grief and depressive symptoms, suicidality, and sleep difficulties were noted from pre- to posttreatment and maintained for 2 months post treatment. Furthermore, she improved her ability to regulate her emotions and cognitions using DBT coping skills and eliminated substance abuse. These results prompt the need for more research to further investigate DBT skills training for PCBD.

Introduction. Fatigue is a distressing symptom for adults with acute leukemia, often impeding their ability to exercise. Objectives. 1) Examine effects of a 4-week mixed-modality supervised exercise program (4 times a week, twice a day) on fatigue in adults with acute leukemia undergoing induction chemotherapy. 2) Evaluate effects of exercise program on cognition, anxiety, depression, and sleep disturbance. 3) Evaluate effect of intervention on adherence to exercise. Methods. 17 adults (8 intervention, 9 control), aged 28-69 years, newly diagnosed with acute leukemia were recruited within 4 days of admission for induction treatment. Patient-reported outcomes (PROs) (fatigue, cognition, anxiety, depression, sleep disturbance, mental health, and physical health) and fitness performance-based measures (Timed Up and Go [TUG], Karnofsky Performance Status, and composite strength scoring) were assessed at baseline and at discharge. Changes in PRO and performance-based physical function measures from baseline to time of discharge were compared between groups using Wilcoxon Rank Sum tests. Results. With PROMIS (Patient-Reported Outcomes Measurement Information System) Fatigue, we found a median change in fatigue (−5.95) for the intervention group, which achieved a minimally important difference that is considered clinically relevant. Intervention group reduced their TUG performance by 1.73 seconds, whereas the control group remained fairly stable. A concerning finding was that cognition decreased for both groups during their hospitalization. 80% adherence of visits completed with a mean of 6 sessions attended per week. Conclusions. Our study provides information on the impact of exercise on symptomatology, with focus on fatigue and other psychosocial variables in acute leukemia.
Biomechanics of the Proximal Radius Following Drilling of the Bicipital Tuberosity to Mimic Cortical Button Distal Biceps Repair Technique
Authors: Oak Nikhil R. , Lien John R. , Brunfeldt Alexander , Lawton Jeffrey N.
Published: March 2017

Background: A fracture through the proximal radius is a theoretical concern after cortical button distal biceps fixation in an active patient. The permanent, nonossified cortical defect and medullary tunnel is at risk during a fall eliciting rotational and compressive forces. We hypothesized that during simulated torsion and compression, in comparison with unaltered specimens, the cortical button distal biceps repair model would have decreased torsional and compressive strength and would fracture in the vicinity of the bicipital tuberosity bone tunnel. Methods: Sixteen fourth-generation composite radius Sawbones models were used in this controlled laboratory study. A bone tunnel was created through the bicipital tuberosity to mimic the exact bone tunnel, 8 mm near cortex and 3.2 mm far cortex, made for the BicepsButton distal biceps tendon repair. The radius was then prepared and mounted on either a torsional or compression testing device and compared with undrilled control specimens. Results: Compression tests resulted in average failure loads of 9015.2 N in controls versus 8253.25 N in drilled specimens ( P = .074). Torsional testing resulted in an average failure torque of 27.3 Nm in controls and 19.3 Nm in drilled specimens ( P = .024). Average fracture angle was 35.1° in controls versus 21.1° in drilled. Gross fracture patterns were similar in compression testing; however, in torsional testing all fractures occurred through the bone tunnel in the drilled group. Conclusion: There are weaknesses in the vicinity of the bone tunnel in the proximal radius during biomechanical stress testing which may not be clinically relevant in nature. Clinical Relevance: In cortical button fixation, distal biceps repairs creates a permanent, nonossified cortical defect with tendon interposed in the bone tunnel, which can alter the biomechanical properties of the proximal radius during compressive and torsional loading.
Medical-Legal Partnership in Primary Care: Moving Upstream in the Clinic
Authors: Tobin Tyler Elizabeth
Published: March 2017

Medical-legal partnership (MLP) is a health care delivery innovation that embeds civil legal aid expertise into the health care team to address health-harming legal needs for vulnerable populations at risk for poor health. The MLP approach focuses on prevention by addressing upstream structural and systemic social and legal problems that affect patient and population health. Because many unmet legal needs affect health (such as residing in substandard housing; wrongful denial of government income supports, health insurance, or food assistance; family violence; and barriers to care based on immigration status), lawyers are important members of the health care team. This review describes the MLP approach to addressing the social determinants of health, examines its benefits for improving the delivery of primary care for vulnerable patients and populations, and explores new opportunities for MLP in primary care with the advent of systems reforms driven by the Affordable Care Act.
On the characterization of pore size distribution of building materials
Authors: Dutra LF , Mendes N , Philippi PC
Published: March 2017

Moisture affects significantly the energy performance of air conditioning systems, the durability of materials, and the health of occupants. One way of reducing those effects, without increasing the energy costs, is by means of using porous material ability of absorbing and releasing moisture from/to the adjacent environment, which attenuates the indoor relative humidity variation. This natural ability is intrinsically related to the porous microstructure. Therefore, the characterization of the pore space is an important research theme in the building physics area. This article aims to present a method for obtaining the pore size distribution based on adsorption isotherms and mercury porosimetry data. First, the theoretical formulation based on the Gibbs free energy for a two-phase (liquid–vapor) system, using the De Boer and Zwikker model, is presented, allowing the calculation of the critical adsorbed thickness for pore filling, critical radius, adsorbed moisture content, capillary condensation content, available surface for adsorption, and the distribution of micropores for a wide range of radius. The adsorption isotherm curve is estimated for high relative humidity values through mercury porosimetry, along with the adsorption curve obtained from the experiment. The pore volume distribution calculated by this method can be used to estimate transport coefficients for liquid and vapor phases.

Published: March 2017

Rationale

Early reperfusion in patients experiencing acute ischemic stroke is effective in patients with large vessel occlusion. No randomized data are available regarding the safety and efficacy of endovascular therapy beyond 6 h from symptom onset.

Aim

The aim of the study is to demonstrate that, among patients with large vessel anterior circulation occlusion who have a favorable imaging profile on computed tomography perfusion or magnetic resonance imaging, endovascular therapy with a Food and Drug Administration 510 K-cleared mechanical thrombectomy device reduces the degree of disability three months post stroke.

Design

The study is a prospective, randomized, multicenter, phase III, adaptive, blinded endpoint, controlled trial. A maximum of 476 patients will be randomized and treated between 6 and 16 h of symptom onset.

Procedures

Patients undergo imaging with computed tomography perfusion or magnetic resonance diffusion/perfusion, and automated software (RAPID) determines if the Target Mismatch Profile is present. Patients who meet both clinical and imaging selection criteria are randomized 1:1 to endovascular therapy plus medical management or medical management alone. The individual endovascular therapist chooses the specific device (or devices) employed.

Study outcomes

The primary endpoint is the distribution of scores on the modified Rankin Scale at day 90. The secondary endpoint is the proportion of patients with modified Rankin Scale 0–2 at day 90 (indicating functional independence).

Analysis

Statistical analysis for the primary endpoint will be conducted using a normal approximation of the Wilcoxon–Mann–Whitney test (the generalized likelihood ratio test).
Algorithmic rationality: Epistemology and efficiency in the data sciences
Authors: Lowrie Ian
Published: March 2017

Recently, philosophers and social scientists have turned their attention to the epistemological shifts provoked in established sciences by their incorporation of big data techniques. There has been less focus on the forms of epistemology proper to the investigation of algorithms themselves, understood as scientific objects in their own right. This article, based upon 12 months of ethnographic fieldwork with Russian data scientists, addresses this lack through an investigation of the specific forms of epistemic attention paid to algorithms by data scientists. On the one hand, algorithms are unlike other mathematical objects in that they are not subject to disputation through deductive proof. On the other hand, unlike concrete things in the world such as particles or organisms, algorithms cannot be installed as the objects of experimental systems directly. They can only be evaluated in their functioning as components of extended computational assemblages; on their own, they are inert. As a consequence, the epistemological coding proper to this evaluation does not turn on truth and falsehood but rather on the efficiency of a given algorithmic assemblage. This article suggests that understanding the forms of algorithmic rationality employed in such inquiry is crucial for charting the place of data science within the contemporary academy and knowledge economy more generally.

Authors: Kouzmina Maria , Koljonen Virve , Leikola Junnu , Böhling Tom , Lantto Eila
Published: March 2017

Background

The primary neuroendocrine skin cancer, Merkel cell carcinoma (MCC), has a well-known predilection to metastasize systemically. However, the experience of systemic metastases in MCC is mainly disseminated through case reports due to the rarity of MCC.

Purpose

To elucidate the frequency and locations of systemic metastasis in MCC by reviewing the imaging of patients with metastatic MCC in a national cohort.

Material and Methods

Patients with diagnosed metastatic MCC by imaging studies in Finland during 1999–2012 were included in this study. We reviewed their imaging studies to evaluate the most frequent sites for systemic metastasis and determined the latency between the primary tumor diagnosis and systemic metastasis. The material includes 30 MCC patients with complete imaging series and 187 examinations, of which 102 (54%) were CT images.

Results

The mean latency from the primary tumor diagnosis to systemic metastasis was 2.1 years and the mean latency between the radiologic diagnosis of the metastases and death was 299 days. Metastases were recorded in several organ systems in most of the cases, and at least two separate metastatic sites in 63% of the cases. Metastatic spread was noted in 60% of the cases in distant lymph nodes. Liver and lungs were the most affected solid organs.

Conclusion

Systemic metastasis in MCC has no predilection site, basically every organ system can be involved. Most of the systemic metastases were recorded during the first two years after the MCC diagnosis.

Published: March 2017

The objective of this study was to assess work-related hygiene practices and the frequency and location of skin rashes due to cutaneous contact with crop-associated materials (e.g., pesticides) for female nursery and fernery workers in Central Florida. A cross-sectional, community-based participatory research study of 237 female nursery and fernery workers between the ages of 19 and 43 years with significant cutaneous contact with foliage crops was conducted using a self-report questionnaire and a skin rash chart assessment tool. Of the 237 farmworkers surveyed, 37.1% ( n = 88) reported a rash on at least one area of their bodies. Women who were pregnant during the study were 4.7 times more likely to report more than 30% total body surface area (TBSA) covered by rash compared with non-pregnant fernery workers ( p = .045; 95% confidence interval [CI] [1.04, 21.35]). Further research is needed to better understand the development of skin rashes among farmworkers, to generate effective prevention strategies.
Less Invasive Surfactant Administration Reduces the Need for Mechanical Ventilation in Preterm Infants
Authors: Lau Christine S. M. , Chamberlain Ronald S. , Sun Shyan
Published: March 2017

Neonatal respiratory distress syndrome due to surfactant deficiency is associated with high morbidity and mortality in preterm infants, and the use of less invasive surfactant administration (LISA) has been increasingly studied. This meta-analysis found that LISA via thin catheter significantly reduced the need for mechanical ventilation within the first 72 hours (relative risk [RR] = 0.677; P = .021), duration of mechanical ventilation (difference in means [MD] = −39.302 hours; P < .001), duration of supplemental oxygen (MD = −68.874 hours; P < .001), and duration of nasal continuous positive airway pressure (nCPAP; MD = −28.423 hours; P = .010). A trend toward a reduction in the incidence of bronchopulmonary dysplasia was observed (RR = 0.656; P = .141). No significant difference in overall mortality, incidence of pneumothorax, or successful first attempts was observed. LISA via thin catheter significantly reduces the need for mechanical ventilation within the first 72 hours as well as the duration of mechanical ventilation, supplemental oxygen, and nCPAP. LISA via thin catheter appears promising in improving preterm infant outcomes.
Mobile hologram verification with deep learning
Authors: Soukup Daniel , Huber-Mörk Reinhold
Published: March 2017

Holograms are security features applied to security documents like banknotes, passports, and ID cards in order to protect them from counterfeiting. Checking the authenticity of holograms is an important but difficult task, as holograms comprise different appearances for varying observation and/or illumination directions. Multi-view and photometric image acquisition and analysis procedures have been proposed to capture that variable appearance. We have developed a portable ring-light illumination module used to acquire photometric image stacks of holograms with mobile devices. By the application of Convolutional Neural Networks (CNN), we developed a vector representation that captures the essential appearance properties of hologram types in only a few values extracted from the photometric hologram stack. We present results based on Euro banknote holograms of genuine and counterfeited Euro banknotes. When compared to a model-based hologram descriptor, we show that our new learned CNN representation enables hologram authentication on the basis of our mobile acquisition method more reliably.
Neutrophils regulate the lung inflammatory response via γδ T cell infiltration in an experimental mouse model of human metapneumovirus infection
Authors: Cheemarla Nagarjuna R , Baños-Lara Ma Del Rocío , Naidu Shan , Guerrero-Plata Antonieta
Published: March 2017

Neutrophils are the most abundant leukocytes in human circulation. They are the first immune cell population recruited to the sites of infection. However, the role of neutrophils to regulate host immune responses during respiratory viral infections is largely unknown. To elucidate the role of neutrophils in respiratory antiviral defense, we used an experimental mouse model of human metapneumovirus (HMPV) infection. HMPV, a member of the Paramyxoviridae family, is a leading respiratory pathogen causing severe symptoms, such as bronchiolitis and pneumonia, in young, elderly, and immunocompromised patients. We demonstrate that neutrophils are the predominant population of immune cells recruited into the lungs after HMPV infection. This led us to hypothesize that neutrophils represent a key player of the immune response during HMPV infection, thereby regulating HMPV-induced lung pathogenesis. Specific depletion of neutrophils in vivo using a mAb and simultaneous infection with HMPV exhibited higher levels of inflammatory cytokines, pulmonary inflammation, and severe clinical disease compared with HMPV-infected, competent mice. Interestingly, the lack of neutrophils altered γδ T cell accumulation in the lung. The absence of γδ T cells during HMPV infection led to reduced pulmonary inflammation. These novel findings demonstrate that neutrophils play a critical role in controlling HMPV-induced inflammatory responses by regulating γδ T cell infiltration to the site of infection.

Purpose

Little is known about neurologic morbidity attributable to cranial radiotherapy (CRT) –associated meningiomas.

Materials and Methods

From 4,221 survivors exposed to CRT in the Childhood Cancer Survivor Study, a diagnosis of meningioma and onset of neurologic sequelae were ascertained. Cox proportional hazards regression was used to estimate hazard ratios (HR) and 95% CIs to evaluate the factors associated with neurologic sequelae after subsequent meningioma.

Results

One hundred ninety-nine meningiomas were identified among 169 participants. The median interval from primary cancer to meningioma diagnosis was 22 years (5 to 37 years). The cumulative incidence of a subsequent meningioma by age 40 years was 5.6% (95% CI, 4.7% to 6.7%). CRT doses of 20 to 29.9 Gy (HR, 1.6; 95% CI,1.0 to 2.6) and doses ≥ 30 Gy (HR, 2.6; 95% CI, 1.6 to 4.2) were associated with an increased risk of meningioma compared with CRT doses of 1.5 to 19.9 Gy ( P < .001). Within 6 months before or subsequent to a meningioma diagnosis, 20% (30 of 149) reported at least one new neurologic sequela, including seizures (8.3%), auditory-vestibular-visual deficits (6%), focal neurologic dysfunction (7.1%), and severe headaches (5.3%). Survivors reporting a meningioma had increased risks of neurologic sequelae > 5 years after primary cancer diagnosis, including seizures (HR, 10.0; 95% CI, 7.0 to 15.3); auditory-vestibular-visual sensory deficits (HR, 2.3; 95% CI, 1.3 to 4.0); focal neurologic dysfunction (HR, 4.9; 95% CI, 3.2 to 7.5); and severe headaches (HR, 3.2; 95% CI, 1.9 to 5.4). With a median follow-up of 72 months after meningioma diagnosis (range, 3.8 to 395 months), 22 participants (13%) were deceased, including six deaths attributed to a meningioma.

Conclusion

Childhood cancer survivors exposed to CRT and subsequently diagnosed with a meningioma experience significant neurologic morbidity.
Do Consumers Take Advantage of Common Pricing Standards? An Experimental Investigation
Authors: Sugden Robert , Zheng Jiwei
Published: March 2017

Gaudeul and Sugden [Gaudeul A, Sugden R (2012) Spurious complexity and common standards in markets for consumer goods. Economica 79(314):209–225] have hypothesized that when some but not all competing products are priced in a common standard, consumers who are liable to make errors in cross-standard price comparisons use decision rules that discriminate in favor of common-standard offers. Such behavior incentivizes sellers to use common standards. We report an experimental test of this hypothesis, using choice tasks similar to those represented in the Gaudeul–Sugden model. We find that offers priced in common standards were more likely to be inspected but less likely to be chosen, and that subjects gained little benefit from common pricing standards that applied to some but not all offers. Most subjects used “dominance editing” operations that eliminated transparently dominated offers, either as an initial shortlisting device or while offers were being sorted. Because these operations discriminate against common-standard offers, their use incentivizes sellers not to use common standards.

Optimal Ordering Policy for Inventory Systems with Quantity-Dependent Setup Costs
Authors: He Shuangchi , Yao Dacheng , Zhang Hanqin
Published: March 2017

We consider a continuous-review inventory system in which the setup cost of each order is a general function of the order quantity and the demand process is modeled as a Brownian motion with a positive drift. Assuming the holding and shortage cost to be a convex function of the inventory level, we obtain the optimal ordering policy that minimizes the long-run average cost by a lower bound approach. To tackle some technical issues in the lower bound approach under the quantity-dependent setup cost assumption, we establish a comparison theorem that enables one to prove the global optimality of a policy by examining a tractable subset of admissible policies. Since the smooth pasting technique does not apply to our Brownian inventory model, we also propose a selection procedure for computing optimal policy parameters when the setup cost is a step function.
Optimal Routing for Plug-In Hybrid Electric Vehicles
Authors: Nejad Mark M. , Mashayekhy Lena , Grosu Daniel , Chinnam Ratna Babu
Published: March 2017

We propose routing algorithms for plug-in hybrid electric vehicles (PHEVs) that account for the significant energy efficiency differences of vehicle operating modes and recommend the predominant mode of operation for each road segment during route planning. This is to enhance fuel economy and reduce emissions. We introduce the energy-efficient routing problem (EERP) for PHEVs and formulate this problem as a new class of the shortest path problem. The objective of the EERP is to not only find a path to any given destination but also to identify the predominant operating mode for each segment of the path to minimize fuel consumption. EERP can be generalized to a new class of problems in the context of network optimization, where for each arc we need to choose which resources to use to minimize the consumption of one of the resources subject to a constraint on the other resource. In this problem, the resource selection is mutually exclusive, which means we cannot choose both resources together for an arc. We prove that the EERP is NP-complete. We then propose two exact algorithms, and a fully polynomial time approximation scheme (FPTAS) to solve the EERP. We demonstrate the performance of our proposed exact and FPTAS algorithms using road network data from Southeast Michigan. The results show that incorporating our proposed algorithms during route planning leads to significant energy savings for PHEVs over simplistic routing algorithms and current practice.
Budgeting Time for Dynamic Vehicle Routing with Stochastic Customer Requests
Authors: Ulmer Marlin W. , Mattfeld Dirk C. , Köster Felix
Published: March 2017

Parcel services route vehicles to pick up parcels in the service area. Pickup requests occur dynamically during the day and are unknown before their actual request. Because of working hour restrictions, service vehicles only have a limited time to serve dynamic requests. As a result, not all requests can be confirmed. To achieve an overall high number of confirmed requests, dispatchers have to budget their time effectively by anticipating future requests. To determine the value of a decision, i.e., the expected number of future confirmations given a point of time and remaining free time budget, we present an anticipatory time budgeting heuristic (ATB) drawing on methods of approximate dynamic programming. ATB frequently simulates a problem’s realization to subsequently approximate the values for every vector of point of time and free time budget to achieve an approximation of an optimal decision policy. Since the number of vectors is vast, we introduce the dynamic lookup table (DLT), a general approach adaptively partitioning the vector space to the approximation process. Compared with state-of-the-art benchmark heuristics, ATB allows an effective use of the time budget resulting in anticipatory decision making and high solution quality. Additionally, the DLT significantly strengthens and accelerates the approximation process.

Biodiversitas 18:Â  295-303.This paper discusses the result of study on introduction of â€˜jengjenâ€™ (Sundanese name) (Paraserianthes falcataria (L.) Nielsen in development of traditional agroforestry, â€˜humaâ€™ in Village of Karangwangi, Sub-district of Cidaun, District of Cianjur, Province of West Java, Indonesia. Method used in this study was qualitative with ethnoecological and biological approach. Observation and deep interview with informants were used to collect data. The result of study shows that although the population of Karangwangi Village has increased, the forest decreased, and intensively penetrated market economy, the huma system has continually practiced by village people. Unlike in the past, nowadays, the huma has been practiced in the non-forest instead of the forest. The huma system has been modified by people to be more permanent of traditional agroforestry system, such as bamboo garden (kebon awi), mixed of wood trees (kebon kai), and mixed fruit and wood trees (talun). In addition, due to more intensive in cultivation of agricultural land, Karangwangi people have adopted and cultivated jengjen plant in the huma farming system that had initially introduced by the Forestry Office (Dinas Kehutanan) through the regreening program. Moreover, the jengjen plant has been adopted and cultivated by the village people, such as integrated in the development of traditional agroforestry huma. It is caused this plant has provided some benefits, such as to improve soil fertility and to provide economic benefits, and does not eliminate the swidden farming (huma) system tradition of the people.

Abstract. Puspitaningtyas DM. 2017. Orchid inventory in Bantimurung-Bulusaraung National Park, South Sulawesi, Indonesia. Biodiversitas 18: 341-350. Bantimurung-Bulusaraung National Park, commonly abbreviated as Babul National Park, is in South Sulawesi. It occupies an area of 43,750 hectares between 119o34'17"-119o55'13" East and 4o42'49"-5o06'42" South. Babul National Park is an area in the transition zone between Asia and Australia and therefore has a unique flora and fauna. The study reported here aimed to inventory the orchid species in the Babul National Park area and to determine the orchid diversity in the area. The results of the study recorded approximately 60 orchid species found in Babul National Park. These were representative of 32 genera and consisted of 42 species of epiphytic orchids and 18 species of terrestrial orchids. The terrestrial orchid Habenaria beccarii and the epiphytic orchid Aerides inflexa were the most common orchids found, and were spread evenly throughout the Babul National Park area. Coelogyne celebensis and Aerides inflexa are endemic orchids of Sulawesi found within the Park. Three species of the genus Nervilia, i.e. N. punctata, N. plicata, and N. aragoana, were also found in this area. Some species of orchid such as Tropidia angulosa, Coelogyne rumphii and Dendrobium lampongense were found as new records in Sulawesi.

The effects of forest degradation revealed severe changes in the hydrological cycle such as variability of water input on forest floor, soil water storage and the ability to abstract water from soil depth. A study had been conducted to investigate part of the water cycle, the amount of water and carbon input through stemflow into peatland forest floor for 2 years. Stemflow was measured on 20 trees of each 3 blocks of forest with tree diameter ranging from 10-30 cm dbh using stemflow collectors. Then the trees were grouped to three bark types (smooth, mid, and coarse) to investigate whether it had influenced the inputs. Results showed that with mean annual precipitation of 3282 Â± 128mm, annual mean stemflow for the area was 18.2% of the rainfall. Further analysis demonstrated that tree species with smoother bark textures tend to bring more water to forest floor compared to mid and coarse bark textures (46% and 42.5% more than coarse and intermediate consecutively). The carbon input also show similar trend. The results implied that tree species influence the amount of stemflow and significant amount of water could be slower down come to forest floor through this mechanism and protected forest soil.

Abstract. Suharno, Soetarto ES, Sancayaningsih RP, Kasiamdari RS.2017. Association of arbuscular mycorrhizal fungi (AMF) with Brachiaria precumbens (Poaceae) in tailing and its potential to increase the growth of maize (Zea mays).Biodiversitas 18: 433-441.The role of Arbuscular Mycorrhizal Fungi (AMF) in the process of rehabilitation of degraded land is very important, including the handling of sand tailings. In the rehabilitation process, utilizing the AMF isolates from the tailings area will be easier to adapt to the habitat that will be rehabilitated. The purpose of this study was to determine AMF that associated with Brachiaria precumbens (Poaceae) derived from the tailings area in Timika, Papua, and its potential to the growth of maize (Zea mays). The methods used to determine the presence of AMF were a survey and wet sieving methods, while the calculation of percent colonization was done by slide method. The compatibility test and effectiveness of AMF inoculation on the maize growth were conducted by completely randomized design (CRD) with 4 treatments: M0: control (without mycorrhiza); M1: Clariodeoglomus etunicatum BGR; M2: C. lamellosum L1A01S; M3: C. etunicatum L3A12D each with eight replications. The results showed that the presence of the AMF in the rhizosphere of B. precumbens was found in the tailings deposition area Modified Ajkwa Deposition Area (ModADA) of a gold mine in Timika. AMF percent colonization at the root reached 73.3%, while the number of spores in the rhizosphere was 8-25 per 10 g samples of soil and increased to reach an average of 49.6 spores per 10 g soil samples by trap methods. Based on the morphological identification, AMF found in the B. precumbens rhizosphere were identified as genus Glomus, Scutellospora, Acaulospora, and Claroideoglomus, whereas based on molecular identification, two isolates (L1A01S and L3A12D) were identified as C. lamellosum L1A01S and C. etunicatum L1A12D. The compatibility test showed that the AMF was able to increase the growth of maize, and significantly affected plant height, leaf area, and relative growth rate. C. lamellosum L1A01S derived from the tailings had a better effect than C. etunicatum L3A12D and C. etunicatum BGR.

Gunung Walat University Forest (GWUF) of Sukabumi, Indonesia is one of pine resin producers that has 71 hectares of resin production area. The forest fire burned 7 hectares of resin production area in August 2015 was expected to affect the resin productivity. The aim of this study was to analyze the effect of each type of forest fire to pine resin productivity and analyze the correlation between the biophysic aspect and pine resin productivity after the fire. The types of forest fire were litter and shrub fire, stem fire, and crown fire. ANOVA test showed that the types of forest fire have significant effect to resin production with the value of Ftable (3.12)<Ftest (4.88) and Pvalue (0.006)<α (0.05). The Tukey test showed that the stem fire and the crown fire gave the most significant result to the resin production with the mean of resin productivity value (g/tree/day) respectively 24.54 and 21.698.

Abstract. Hedayati A, Pouladi M, Vazirizadeh A, QadermarziA, Mehdipour N. 2017. Seasonal variations in abundance and diversity of copepods in Mond River estuary, Bushehr, Persian Gulf. Biodiversitas 18: 447-452. The present study was carried out to investigate the abundance and biodiversity of copepods from Mond River (MR) estuary, Bushehr, Persian Gulf during 4 seasons and their relationships with environmental factors. The water samples were collected in mid-season from spring 2012 to winter 2013 for one year period. Copepod samples were collected by using of 140 Âµm plankton net with 25 cm mouth diameter and vertical towing in all stations. Copepod assemblages were comprised of 4 orders, 13 families and 10 genera. Orders were included; Calanoida, Cyclopoida, Poecilostomatoida, Harpacticoida and Genera were included: Cathocalanus, Acrocalanus, Paracalanus, Subeucalanus, Centropages, Temora, Calanopia, Labidocera, Pontella, Acartia, Oithona, Oncaea, Corycaeus, Microsetella, Microsetella and Euterpina. The order Calanoida with 10 genera was the most diverse and dominant order between Identified orders. The means (Â±SE) of copepods abundance were recorded in spring (5853.4Â±1826.19 Individual m-3), in summer (6707.6Â±1930.15 Ind. m-3), in fall (4393.6Â±1263.37 Ind. m-3) and in winter (3400Â±763.98 Ind. m-3), respectively. Simpson and Shannon-Wiener biodiversity indices were obtained in spring (0.87Â±0.11 and 2.86Â±0.19), in summer (0.89Â±0.006 and 3.11Â±0.15), in fall (0.86Â±0.13 and 2.66Â±0.2) and in winter (0.83Â±0.12 and 2.39Â±0.15), respectively. The copepod assemblages had most amounts of diversity and abundance at station 5 in all seasons. Pearson correlation showed significant correlation between copepod diversity and abundance with salinity, pH and temperature. Results showed that salinity factor was more effective environmental factor on Simpson (0.01> P and r=0.783) and Shannon-Weiner indices (0.01> P and r=0.727), and copepods abundance (0.01> P and r=0.664) in MR estuary.

Rizal A, Dewanti LP. 2017. Using economic values to evaluate management options for fish biodiversity in the Sikakap Strait, Indonesia. Biodiversitas 18: 575-581. The unavailability of total economic values of fish biodiversity in Sikakap Strait, Mentawai District of West Sumatra, Indonesia both in the short and long term, has created the rejection of their existences in the coastal area. The purpose of this study was to estimate the total economic value of fish biodiversity in Sikakap Strait, West Sumatra using total economic value concepts. The fish biodiversityâ€™s total economic value is expressed by estimating the use value, indirect use value and non-use value. The study used benefit transfer and survey methods using secondary data to estimate the total economic value of fish biodiversity. The total economic value of the fish biodiversity of USD 745,602 per year was calculated by summing the direct use value (USD 4,262,884 per year), indirect use value (USD 24,560 per year), and non-use value (USD 575 per year). The research hypothesis that the fish biodiversityâ€™s sustainable resource management has economic value is supported. These values help to make decisions about allocating resources between competing uses.

Rahmawathi AM, Wijayanto N, Wulandari AS. 2017. Short Communication: Growth analysis of sentang (Azadirachta excelsa) in agroforestry system. Biodiversitas 18: 589-592. Sentang is one of forestry plants which can be planted in agroforestry system. It is one of the important medicinal plants grown in different agroforestry systems and contains an active compound of azadirachtin. It has cone crown and balance branch that makes it suitable to be cultivated in agroforestry system which utilizes lower stratum or ground. This research aimed to analyze growth and nutrient content of sentang in agroforestry and monoculture system. Plantation site was in Conservation Unit Research Center for Biopharmaceutical IPB. The sentang was two years old. The design was complete randomized design with one factor (cropping system) and two treatments (agroforestry and monoculture). The results showed the increase of sentang height was higher in agroforestry system than the monoculture due to additional nutrition obtained by sentang in agroforestry system derived from fertilizing activity at the beginning of soybean planting. Nutrient content of sentang was higher in agroforestry plot than monoculture. Fertilizing activity of soybean led to an increase of sentang in agroforestry system.
