Published: March 2018

Community-based forest management program provides the access for communities to participate in managing state forests. One of them is conducted through agroforestry planting pattern in village forest. The purpose of this research is to know the performance of agroforestry management on land managed by Sumur Kumbang village community in Protected Forest Management Area of Rajabasa. The data collection was got through by interview and observation; the data obtained were analyzed descriptively. The results show the performance of agroforestry management in protected forest management area of Rajabasa in moderate performance (productivity 84, sustainability 167, fairness benefit 88, and efficiency 168). Such performance is influenced by forest management system, ie controlled lands and individually controlled forest products; agroforestry business orientation is commercial; and forest structure is a complex agroforestry. Therefore, the Protected Forest Management Unit of Rajabasa and related stakeholders should develop community capacity and strengthen local institutions continuously so that their forests can be managed in a fair, beneficial, and sustainable way.Keyword : agroforestry; village forest; protected forest management unit; performance..Program pengelolaan hutan berbasis masyarakat memberikanakses bagi masyarakat untuk berpartisipasi mengelola hutan negara;salah satunya dilakukan melalui pola tanam agroforestri di hutan desa.

The purpose of this research is to get the distribution of erosion tolerance value (T-value) in KedungOmbo Dam Catchment Area. The KedungOmbo Dam Catchment Area is located in Boyolali area as a food granary with the main supply of vegetables and rice producers. This situation requires soil conditions to be maintained and no land degradation or erosion that exceeds the limits of erosion or erosion tolerance allowed. The method used to calculate the T-value is the survey and by the calculation of raster analysis with satellite imagery. The parameter collected in the field includes soil conditions (soil solum) and crop conditions (effective root depth). Based on T-value calculation formula with 300 years life resource, this will get the amount of erosion allowed in KedungOmbo Dam Catchment Area. Areas with low T values should be maintained for land conditions because mild erosion will be a serious threat. The erosion tolerance in the KedungOmbo Dam Catchment Area is 59%, which is dominated by high T-values, with an area of 34,092 ha and a very high 24% or an area of 14,136 ha.Keywords: Land degradation; Sheet erosion; Value-T; Land productivityTujuan dari penelitian ini untuk mendapatkan sebarannilai toleransi erosi (nilai-T) di Daerah Tangkapan Waduk (DTW) Kedung Ombo. Mengingat DTW Kedung Ombo termasuk wilayah Boyolali sebagai lumbung pangan dengan pasokan utama sayuran dan juga produsen padi. Situasi ini membutuhkan kondisi tanah harus dipertahankan dan tidak ada degradasi lahan atau erosi yang melebihi batas toleransi erosi atau erosi diperbolehkan. Metode yang digunakan untuk menghitung nilai-T dengan cara survei dan dibantu dengan perhitungan analisis raster dengan citra satelit. Parameter yang dikumpulkan di lapangan meliputi kondisi tanah (solum tanah) dan kondisi tanaman (kedalaman perakaran efektif). Dari rumus perhitungan nilai-T dengan resource life 300 tahun akan mendapatkan besarnya erosi yang diperbolehkan di seluruh DTW Kedung Ombo. Daerah dengan nilai T yang rendah harus dijaga kondisi lahannya, karena erosi ringan saja akan menjadi ancaman serius. Toleransi erosi di DTW Kedung Ombo 59% didominasi oleh nilai-T yang tinggi, seluas 34.092 ha dan sangat tinggi 24% atau seluas 14.136 ha.Kata kunci: Degradasi lahan; Erosi permukaan; Nilai-T; Produktivitas lahan

Published: March 2018

The availability of natural agarwood tends to decrease and encourage some parties to cultivate agarwood producing plants by using biological inoculation method that is microbe. In relation to this, many manufacturers produce inoculant products used to inoculate agarwood trees. This research is aimed to get some agarwood inoculant products in South Kalimantan. The inoculant products used in this study were obtained based on information from agarwood farmers in South Kalimantan. Based on observation result, inokulan products have varied form ie liquid, capsule, and stick. In addition, these products do not fullfil the packaging standards such as the absence of date of manufacture, trade license, and expiry date. The result of identification of dominant microbes inokulan product design showed some products formed from microbial species that function in agarwood formation that have not been studied even at risk of endangering human health. The results of this study are expected to be an input for farmers to be more careful in choosing the right inoculantproducts and become a driver for producers to improve the quality of inoculants produced.slsKeyword: inoculants; fungi; agarwood; quality; south kalimantanKetersediaan gubal gaharu alam semakin menurun, mendorong beberapa pihak untuk membudidayakan tanaman penghasil gaharu dengan menggunakan metode inokulasi biologis yaitu mikroba.

Defense Mechanisms against Viral Infection in Drosophila: RNAi versus Non-RNAi
Authors: Swevers Luc , Liu Jisheng , Smagghe Guy
Published: March 2018

RNAi is considered a major antiviral defense mechanism in insects but its relative importance compared to other antiviral pathways has not been evaluated comprehensively. Here, it is attempted to give an overview of the antiviral defense mechanisms in Drosophila that involve both RNAi and non-RNAi to acquire a sense of their relative importance. While RNAi is considered important in most viral infections, many other pathways can exist that confer antiviral resistance. It is noted that very few direct recognition mechanisms of virus infections have been identified in Drosophila and that the activation of immune pathways may be accomplished indirectly through cell damage incurred by viral replication. In several cases, protection against viral infection can be obtained in RNAi mutants by non-RNAi mechanisms, confirming the variability of the RNAi defense mechanism according to the type of infection and the physiological status of the host. This analysis invites to investigate more systematically the relative contribution of RNAi in the antiviral response and more specifically to ask whether RNAi efficiency is affected when other defense mechanisms predominate. While Drosophila can function as a useful model, this issue may be more critical for economically important insects that are either controlled (agricultural pests and vectors of diseases) or protected from parasite infection (beneficial insects as bees) by RNAi products.
Quasi-Equilibrium, Multi-Foil Platelets of Copper and Titanium Substituted Bismuth Vanadate, Bi2V0.9(Cu0.1−xTix)O5.5−δ, by Molten Salt Synthesis
Authors: Ring Kevin , Fuierer Paul
Published: March 2018

10% copper substituted (BiCUVOX/Bi2V0.9Cu0.1O5.5−δ) and 5% copper/titanium double-substituted bismuth vanadate (BiCUTIVOX/Bi2V0.9(Cu0.05Ti0.05)O5.5−δ) platelets were formed by molten salt synthesis (MSS) using a eutectic KCl/NaCl salt mixture. The product was phase pure within the limits of X-ray diffraction. The size and form of the platelets could be controlled by changing the heating temperature and time. The crystallite growth rate at a synthesis temperature of 650 °C, and activation energy for grain growth were determined for BICUTIVOX, which experienced inhibited growth compared to BICUVOX. Quasi-equilibrium, multi-foil shapes consisting of lobes around the perimeter of the platelets were observed and explained in the context of relative two-dimensional nucleation and edge growth rates.

Published: March 2018

This
study was designed to evaluate the phenolic compounds and the in vitro antioxidant and antimicrobial
activities of Onobrychis nitida,
Hedysarum cappadocicum, Ebenus laguroides and Ebenus macrophylla which are
medicinal plants and endemic for the flora of Turkey. The RP-HPLC-DAD (reverse
phase-high performance liquid chromatography with a diode array detector) was
used to evaluate the phenolic contents. The antioxidant properties were
determined to use total phenolic content (TPC), ferric reducing antioxidant
power (FRAP), and DPPH• radical scavenging activity assays. Antibacterial tests
were performed against 11 different microorganisms by using the microwell
dilution method. Each of the plant extracts were confirmed by bioactive assays
which demonstrated a significant activity due to different chemical
characteristics. Especially, rutin was the dominant component in Ebenus species with 19.434-11.808 mg
phenolic/g extract. While the highest phenolic content (101.73 mg gallic acid
equivalent/g extract) was observed in O.
nitida, the highest FRAP value was in E.
laguroides (719.09 μM FeSO4.7H2O equivalent), and the
strongest DPPH degree was in the E.
macrophylla extract with IC50: 69.45 μg/mL, respectively.  Although plant extracts didn’t have efficient
values for antimicrobial activity, the slight effect was arisen in O. nitida against B. subtilis and S. aureus.
The results showed that all the extracts could be used in pharmacological or
dietary applications due to their valuable properties.
Sobre la verdad de la palabra
Authors: Cadavid Ramírez Lina Marcela
Published: March 2018

El título de esta presentación alude, intencionalmente, al libro de Hans-Georg Gadamer Arte y verdad de la palabra, y específicamente al artículo “Acerca de la verdad de la palabra”. Allí, el filósofo se pregunta “¿Cuál es la palabra auténtica, es decir, no la palabra en que se dice algo verdadero o incluso la verdad suprema sino la palabra en su sentido más auténtico?” (1998, p. 20). La pregunta es patente, no indaga sobre el problema de la verdad sino sobre la posibilidad que tiene la palabra de ser ella misma.
El capitalismo tardío como economía política del goce. Aportes de la teoría social lacaniana para su análisis crítico
Authors: Belén Blanco Ana , Soledad Sánchez María
Published: March 2018

Este artículo explora las principales herramientas heurísticas que la teoría social de herencia lacaniana ofrece para el análisis crítico del capitalismo contemporáneo en términos de una economía política del goce. Para ello, a partir de un ejercicio de modelización paradigmática, comenzaremos delimitando los supuestos subyacentes, así como del conjunto de categorías generales y específicas, que definen los contornos de la denominada teoría social lacaniana frente a otras vertientes analíticas que comparten con esta el heteróclito y prolífico campo del posestructuralismo. De allí que, en primer lugar, sistematizaremos los desarrollos conceptuales que el propio Lacan ha legado en su obra tardía, articulados en torno a la noción de discurso capitalista. Una noción que busca caracterizar el malestar en nuestra época al dar cuenta del establecimiento de una economía simbólica y afectiva singular. Luego, y en diálogo con las lecturas contemporáneas que son herederas de tales desarrollos, se avanza en la problematización de los posibles horizontes y estrategias para la transformación de esta forma de lazo social, teniendo por hipótesis que lucha política emancipatoria está ligada primordialmente a la producción y radicalización de los antagonismos sociales que permitirían la inscripción de fisuras en un discurso capitalista que se pretende sin cortes, global y totalizante. © Universidad Católica Luis Amigó - Revista Colombiana de Ciencias Sociales.
El memorial del 68 en México: la construcción de la memoria colectiva sobre un movimiento social emblemático
Authors: Kuri Pineda Edith
Published: March 2018

En 2007 fue inaugurado el Memorial del 68, gestionado por la Universidad Nacional Autónoma de México, con el propósito de coadyuvar a la construcción de la memoria sobre el movimiento estudiantil de 1968, suceso histórico ineludible en la lucha por las libertades democráticas en México. El presente artículo tiene como objetivo analizar sociológicamente la forma en que este espacio fue erigido; qué factores políticos y sociales posibilitaron su constitución y en qué consiste esta propuesta museográfica. Para responder dichas interrogantes, se aplicaron técnicas de investigación cualitativas –entrevistas a los fundadores de este lugar de memoria y ejercicios de observación participante-. Se parte del supuesto de que toda memoria colectiva es una construcción social, política, cultural e histórica que tiende puentes entre las diversas temporalidades, y como tal, es cambiante. Como se verá a lo largo de este trabajo, el Memorial del 68 constituye un discurso memorístico con un claro revestimiento simbólico, en el que convergen elementos afectivos y axiológicos, y cuya articulación revela la manera en que el pasado es interpretado desde las mismas necesidades del presente. © Universidad Católica Luis Amigó - Revista Colombiana de Ciencias Sociales.
Understanding water-related emotional distress for improving water services: a case study from an Ethiopian small town
Authors: Thomas Vincent , Godfrey Samuel
Published: March 2018

This paper introduces the concept of emotional distress as a means of measuring the direct experience of inadequate access to drinking water in a small town in Ethiopia under the UNICEF-Government of Ethiopia urban ONEWASH plus programme. The paper explores a new perspective on the relationship between water technologies, water services, household socio-economic characteristics (as predictors) and mental health in its broad definition. Results indicate that water-related emotional distress is predominantly associated with the ‘cost of water’ and the ‘size of household’. Quantity of water, reliability of the preferred source and accessibility were not significant predictors to emotional distress. Whether the household accessed a pipe into a compound or another improved source was not a significant predictor either. The safely managed target in the Sustainable Development Goal (SDG) 6.1 focuses on the affordability, accessibility and safety of water but does not explore the relation between cost and water-related emotional distress. This evidence offers a complementary approach to the ‘affordability of water services’ as it looks beyond the mere financial implications of water costs.
Membrane defouling using microbubbles generated by fluidic oscillation
Authors: Harun M. H. C. , Zimmerman William B.
Published: March 2018

Impurities and colloidal substances are two of many fouling conditions that reduce the membrane filtration performance used in wastewater treatment. This study investigates the potential of fluidic-oscillation-generated microbubbles (MBs) to defoul the filtration membrane. Cartridge filters for microfiltration (MF) of 1 μm pore size were fouled using surface seawater collected from the Hull coastal area. The seawater was circulated at 5.8 L/min to actuate colloidal substance deposition on the membrane surface. The recorded feed channel pressure drop (ΔP) across the membrane filters showed rapid fouling occurred in the first 8 hrs of the circulation. Fluctuations of ΔP during the next 8 hrs were observed showing the colloids filling the pores of the membrane, and remaining steady for 2 hrs showing the membrane was completely fouled. The filtration membrane was cleaned and defouled using fluidic-oscillator-generated MBs. The fouled membranes were sparged with 1 L/min of air scouring for ∼1 to ∼2 hrs to remove the deposited colloids and impurities on the surface of the membrane. The membrane, analysed by Scanning Electron Microscopy (SEM), UV254 and Electrical Conductivity (EC) meter, showed the extent of MBs-mediated removal of the deposited colloidal particle from the membrane surfaces. This study found that the highest defouling rate occurs with MBs generated by fluidic oscillator (closed vent), followed by MBs generated by fluidic oscillator (opened vent) and MBs generated without fluidic oscillator at 9.53, 6.22, and 3.41 mbar/min, respectively.
Application of forward osmosis membrane in nanofiltration mode to treat reverse osmosis concentrate from wastewater reclamation plants
Authors: Jamil Shahzad , Jeong Sanghyun , Vigneswaran Saravanamuthu
Published: March 2018

Reverse osmosis concentrate (ROC) from wastewater reclamation plants have high concentrations of organic and inorganic compounds, which have to be removed before its disposal. Forward osmosis (FO) and nanofiltration (NF) membranes were tested to treat the ROC for possible water reuse. This research investigated the combined and individual influence of organic and inorganic matter on the fouling of NF and FO membranes. The results revealed that the NF membrane removed most of the organic compounds and some inorganics. The study further highlighted that the FO membrane at NF mode removed the majority of the inorganic compounds and some organics from the ROC. A pretreatment of granulated activated carbon (GAC) adsorption removed 90% of the organic compounds from ROC. In addition, GAC adsorption and acid pretreatment of ROC improved the net water permeate flux by 17% when an FO membrane was used in the NF system. Acid treatment (by bringing the pH down to 5) helped to remove inorganic ions. Therefore, the resultant permeate can be recycled back to the RO water reclamation plant to improve its efficiency.

Published: March 2018

Constantly, the odors coming from sewage plants are considered a problem by the population. The purpose of this study was to evaluate the microbial community present in a full scale biofilter used for odor treatment. The filter was packed with peat. The main gas treated was hydrogen sulphide (H2S). The removal efficiency reached 99%, with an empty bed residence time of 30 seconds. Molecular analysis can enhance our understanding of the microbial communities in biofilters treating wastewater odor. The analysis made to characterize microbial community was High-throughput 16S rRNA sequencing analysis MiSeq® Illumina. The sampling, carried out in the year 2015, was seasonal (summer and winter) and spatial (depth and position in the biofilter). In this study, a total of 206,174 raw sequence reads for six samples were analyzed using Mothur software (v 1.33.3) based on MiSeq SOP protocol. After Mothur analysis, the results of the bacterial community were explored at the Phylum and Genus levels. In this study, the efficiency removal of hydrogen sulfide reached values greater than 99% during the monitoring, and the main bacterial genera found were Acidotermus, Telmatobacter, Methylovirgula and Bryobacter representing the bacterial community active in the transformation of H2S into a system with long operating time.
Video-Based Communication Assessment: Development of an Innovative System for Assessing Clinician-Patient Communication (Preprint)
Authors: Mazor Kathleen M , King Ann M , Hoppe Ruth B , Kochersberger Annie O , Yan Jie , Reim Jesse D
Published: March 2018

UNSTRUCTURED

Good clinician-patient communication is essential to provide quality health care and is key to patient-centered care. However, individuals and organizations seeking to improve in this area face significant challenges. A major barrier is the absence of an efficient system for assessing clinicians’ communication skills and providing meaningful, individual-level feedback. The purpose of this paper is to describe the design and creation of the Video-Based Communication Assessment (VCA), an innovative, flexible system for assessing and ultimately enhancing clinicians’ communication skills. We began by developing the VCA concept. Specifically, we determined that it should be convenient and efficient, accessible via computer, tablet, or smartphone; be case based, using video patient vignettes to which users respond as if speaking to the patient in the vignette; be flexible, allowing content to be tailored to the purpose of the assessment; allow incorporation of the patient’s voice by crowdsourcing ratings from analog patients; provide robust feedback including ratings, links to highly rated responses as examples, and learning points; and ultimately, have strong psychometric properties. We collected feedback on the concept and then proceeded to create the system. We identified several important research questions, which will be answered in subsequent studies. The VCA is a flexible, innovative system for assessing clinician-patient communication. It enables efficient sampling of clinicians’ communication skills, supports crowdsourced ratings of these spoken samples using analog patients, and offers multifaceted feedback reports.
Adolescents� Perspectives on Using Technology for Health: Qualitative Study (Preprint)
Authors: Radovic Ana , McCarty Carolyn A. , Katzman Katherine , Richardson Laura P.
Published: March 2018

BACKGROUND

Adolescents’ wide use of technology opens up opportunities to integrate technology into health visits and health care. In particular, technology has the potential to influence adolescent behavior change by offering new avenues for provider communication and support for healthy choices through many different platforms. However, little information exists to guide the integration of technology into adolescent health care, especially adolescents’ perspectives and preferences for what they find useful.

OBJECTIVE

This qualitative study aimed to take a broad approach to understanding adolescents’ use of technology for supporting their overall health and to understand whether and how adolescents envision using technology to enhance their health and clinical care, particularly in communicating with their provider.

METHODS

Adolescents (13-18 years) were recruited to participate in semi-structured, in-depth individual interviews. Potential participants were approached in-person through the Seattle Children's Hospital Adolescent Medicine Clinic while they were waiting for consultation appointments, through outreach to youth who expressed interest in other local research study activities, and via flyers in waiting rooms. Interviews were recorded, transcribed, and analyzed using a thematic analysis approach.

RESULTS

Thirty-one adolescents (58% female, mean age 15.2 years) were interviewed and described 3 main uses of technology: (1) to gather information, (2a) to share their own experiences and (2b) view others’ experiences in order to gain social support or inspiration, and (3) to track behaviors and health goals. Perceived benefits and potential downsides were identified for technology use. Teens desired to use technology with their provider for 3 main reasons: (1) have questions answered outside of visits, (2) have greater access to providers as a way to build relationship/rapport, and (3) share data regarding behaviors in between visits. Social media was not a preferred method for communicating with providers for any of the youth due to concerns about privacy and intrusiveness.

CONCLUSIONS

Although youth are avid users of technology in general, in regard to technology for health, they display specific use preferences especially in how they wish to use it to communicate with their primary care provider. Health care providers should offer guidance to youth with regard to how they have used and plan to use technology and how to balance potential positives and negatives of use. Technology developers should take youth preferences into account when designing new health technology and incorporate ways they can use it to communicate with their health care provider.
Number needed to treat in indirect treatment comparison
Authors: Guyot Patricia , Cheng Wei , Tremblay Gabriel , Copher Ronda , Burnett Heather , Li Xuan , Makin Charles
Published: March 2018

Aim:
For dichotomous outcomes, odds ratio (OR) is one of the usual summary measures of indirect treatment comparison. A corresponding number needed to treat (NNT) estimate may facilitate understanding of the treatment effect.
Methods:
We show how to estimate NNT based on OR results of a matching adjusted indirect comparison. We also have derived the explicit formula of its 95% CIs by applying the delta method, and as an alternative, a simulation-based method.
Results:
The method was applied in a case study example in radioiodine-refractory differentiated thyroid cancer (RR-DTC) patients, comparing lenvatinib to sorafenib. For every two RR-DTC patients treated with lenvatinib instead of sorafenib, one fewer would have progressed and for every eight RR-DTC patients treated with lenvatinib instead of sorafenib, one fewer would have died.
Conclusion:
Using NNT to summarize the results of a matching adjusted indirect comparison can help the clinicians to better understand the results in addition to OR.
Economic and organizational impact of the changing hospital funding practices of erythropoiesis-stimulating agents on the management of care of dialysis patients in France
Authors: Therasse Carole , Fusier Isabelle , Cordonnier Anne-Laure , Bérard Florence , de Curzon Olivier Parent , Bocquet François , Paubel Pascal
Published: March 2018

Aim:
Erythropoiesis-stimulating agents (ESAs) are particularly used to treat dialysis patients suffering from anemia due to renal failure. Since March 2014, ESAs have no longer been funded on top-of-diagnosis-related groups (DRGs) in French hospitals and are funded via DRGs. There are two ways to fund dialysis in French hospitals: the ‘DRG for dialysis in session’ and the ‘off-dialysis DRG’, which is not a DRG and consists in a supplement tariff specific to dialysis for patients hospitalized for another main reason than dialysis. The aim of this study is to assess the impact of this funding change on the dialysis activity and on the budget of the 37 University Public University Hospitals in Paris (10% of the hospitalizations in France).
Materials & methods:
A before–after study (March–September 2013 vs March–September 2014) was conducted. Medical activity data (and ESAs consumption data) were used to assess the number and costs of DRGs associated with ESAs use. As we do not have access to the whole dialysis activity over the period studied, two hypotheses were considered: the proportion of the dialysis activity was constant between the two periods (Hypothesis A); the dialysis activity was correlated to ESA consumptions delivered by hospital pharmacies to healthcare units (Hypothesis B). A budget impact analysis was also conducted taking into account the evolution of DRG costs and ESA prices.
Results:
The number of dialysis ‘DRG for dialysis in session’ with ESA consumption have increased by 5% (Hypothesis A) and decreased by 9% (Hypothesis B) between the two periods while the volume of ‘off-dialysis DRG’ with ESA consumption increased by 2% (Hypothesis A) and by 9% (Hypothesis B). The budget impact was -€1.02 million (Hypothesis A) and -€0.7 million (Hypothesis B) leading to a loss for our hospitals.
Conclusion:
There is no significant impact of the change of funding of ESAs on the hospital activity. The DRG-based payment is negative for the budget of our hospitals but is positive for the French National Health Insurance. Indeed, with the price decrease, the ESAs are more costly for hospitals (not funded on top-of-DRG), but less costly for the society.

Non-Shannon inequalities in the entropy vector approach to causal structures
Authors: Weilenmann Mirjam , Colbeck Roger
Published: March 2018

A causal structure is a relationship between observed variables that in general restricts the possible correlations between them. This relationship can be mediated by unobserved systems, modelled by random variables in the classical case or joint quantum systems in the quantum case. One way to differentiate between the correlations realisable by two different causal structures is to use entropy vectors, i.e., vectors whose components correspond to the entropies of each subset of the observed variables. To date, the starting point for deriving entropic constraints within causal structures are the so-called Shannon inequalities (positivity of entropy, conditional entropy and conditional mutual information). In the present work we investigate what happens when non-Shannon entropic inequalities are included as well. We show that in general these lead to tighter outer approximations of the set of realisable entropy vectors and hence enable a sharper distinction of different causal structures. Since non-Shannon inequalities can only be applied amongst classical variables, it might be expected that their use enables an entropic distinction between classical and quantum causal structures. However, this remains an open question. We also introduce techniques for deriving inner approximations to the allowed sets of entropy vectors for a given causal structure. These are useful for proving tightness of outer approximations or for finding interesting regions of entropy space. We illustrate these techniques in several scenarios, including the triangle causal structure.

ABSTRACT
This study aims to analyze the dynamics of land tenure in the multi-ethnic society. This research was conducted in District of Randangan,Pohuwato Regency. With a qualitative approach, this research involved 27 informants from various ethnic backgrounds (Gorontalo, Java, Bali, and Bugis) and profession (bureaucracy, NGO, and academic actors). The results of this study indicate that land tenure in the study sites has ethnic dimensions. This is evidenced by the existence of land tenure segregation, in which Bugis ethnic control of land in the coastal areas used for fishpond activities. Furthermore, ethnic Javanese controlled land in the hilly areas used as agricultural and plantation activities, while the ethnic Gorontalo (local), more widely spread in the sub-district government structure, and private. The existence of segregation of land tenure, trigger the emergence of turmoil in society by using ethnic identity as its domain. Therefore, the issue of locals versus migrants colored the polemic at the study site.Furthermore, the granting of access is also based on several actors’ interests, including socio-economic, political, and demographic interests.
Keywords: Dynamics, land tenure, multiethnic society

ABSTRAK
Penelitian ini bertujuan untuk menganalisis dinamika penguasaan lahan dalam masyarakat multietnik. Penelitian ini dilaksanakan di Kecamatan Randangan Kabupaten Pohuwato. Dengan pendekatan kualitatif, penelitian ini melibatkan 27 informan dari berbagai latar belakang etnik (Gorontalo, Jawa, Bali. dan Bugis) dan profesi (birokrasi, LSM, dan akademisi). Hasil penelitian ini menunjukkan bahwa penguasaan lahan di lokasi studi memiliki dimensi etnisitas. Hal ini dibuktikan oleh adanya segregasi penguasaan lahan, di mana etnik Bugis menguasai lahan di wilayah “pesisir” yang digunakan untuk aktivitas tambak ikan. Selanjutnya, etnis Jawa menguasai lahan di wilayah “perbukitan” yang digunakan sebagai aktivitas pertanian dan perkebunan, sedangkan etnis Gorontalo (lokal), lebih banyak tersebar di struktur pemerintahan kecamatan, dan swasta. Adanya segregasi penguasaan lahan, memicu timbulnya gejolak di masyarakat dengan menggunakan identitas etnis sebagai domainnya. Oleh karena itu, isyu penduduk lokal versus pendatang mewarnai polemik di lokasi studi. Di sisi lain, proses penguasaan lahan di lokasi studi dilatar-belakangi oleh adanya keterlibatan berbagai aktor (berbasis etnis) dalam pemberian akses kepada anggota etnisnya masing-masing. Selanjutnya, pemberian akses juga didasarkan pada beberapa kepentingan aktor, di antaranya adalah kepentingan sosial-ekonomi, politik, dan demografi.

Radius of convexity of partial sums of odd functions in the close-to-convex family
Authors: Agrawal Sarita , Sahoo Swadesh
Published: March 2018

We consider the class of all analytic and locally univalent functions f of
the form f(z)=z + ??,n=2 a2n-1z2n-1, ?z? < 1, satisfying the condition
Re(1+zf''(z)/f'(z)) >-1/2. We show that every section s2n-1(z)
= z+ ?n,k=2 a2k-1z2k-1, of f, is convex in the disk ?z? < ?2/3. We also
prove that the radius ?2/3 is best possible, i.e. the number ?2/3 cannot
be replaced by a larger one.
A fixed point theorem for mappings on the l∞-sum of a metric space and its application

Published: March 2018

The aim of this paper is to prove a counterpart of the Banach fixed point
principle for mappings f: l?(X)? X, where X is a metric space and l?(X) is
the space of all bounded sequences of elements from X. Our result generalizes
the theorem obtained by Miculescu and Mihail in 2008, who proved a
counterpart of the Banach principle for mappings f:Xm ? X, where Xm is the
Cartesian product of m copies of X. We also compare our result with a recent
one due to Secelean, who obtained a weaker assertion under less restrictive
assumptions. We illustrate our result with several examples and give an
application.

Leptin acts via its receptor (LepRb) to modulate gene expression in hypothalamic LepRb-expressing neurons, thereby controlling energy balance and glucose homeostasis. Despite the importance of the control of gene expression in hypothalamic LepRb neurons for leptin action, the transcriptional targets of LepRb signaling have remained undefined because LepRb cells contribute a small fraction to the aggregate transcriptome of the brain regions in which they reside. We thus employed translating ribosome affinity purification followed by RNA sequencing to isolate and analyze mRNA from the hypothalamic LepRb neurons of wild-type or leptin-deficient (Lepob/ob) mice treated with vehicle or exogenous leptin. Although the expression of most of the genes encoding the neuropeptides commonly considered to represent the main targets of leptin action were altered only following chronic leptin deprivation, our analysis revealed other transcripts that were coordinately regulated by leptin under multiple treatment conditions. Among these, acute leptin treatment increased expression of the transcription factor Atf3 in LepRb neurons. Furthermore, ablation of Atf3 from LepRb neurons (Atf3LepRbKO mice) decreased leptin efficacy and promoted positive energy balance in mice. Thus, this analysis revealed the gene targets of leptin action, including Atf3, which represents a cellular mediator of leptin action.

OBJECTIVE

Despite advances in technology, optimal glucose control remains elusive and neonatal complications remain ubiquitous in type 1 diabetes (T1D) pregnancy. Our aim was to examine the safety, efficacy, and longer-term feasibility of day-and-night closed-loop insulin delivery.

RESEARCH DESIGN AND METHODS

We recruited 16 pregnant women (mean [SD]: age 32.8 [5.0] years, T1D duration 19.4 [10.2] years, HbA1c 8.0% [1.1], and BMI 26.6 [4.4] kg/m2) to an open-label, randomized, crossover trial. Participants completed 28 days of closed-loop and sensor-augmented pump (SAP) insulin delivery separated by a washout period. Afterward, participants could continue to use the closed-loop system up to 6 weeks postpartum. The primary end point was the proportion of time with glucose levels within the target range (63–140 mg/dL).

RESULTS

The proportion of time with glucose levels within target was comparable during closed-loop and SAP insulin delivery (62.3 vs. 60.1% [95% CI −4.1 to 8.3]; P = 0.47). Mean glucose and time spent hyperglycemic >140 mg/dL also did not differ (131.4 vs. 131.4 mg/dL [P = 0.85] and 36.6 vs. 36.1% [P = 0.86], respectively). During closed-loop, fewer hypoglycemic episodes occurred (median 8 [range 1–17] vs. 12.5 [1–53] over 28 days; P = 0.04) and less time at <63 mg/dL (1.6 vs. 2.7%; P = 0.02). Hypoglycemia <50 mg/dL (0.24 vs. 0.47%; P = 0.03) and low blood glucose index (1.0 vs. 1.4; P = 0.01) were lower. Less nocturnal hypoglycemia (2300–0700 h) during closed-loop therapy (1.1 vs. 2.7%; P = 0.008) and a trend toward higher overnight time in target (67.7 vs. 60.6%; P = 0.06) were found.

CONCLUSIONS

Closed-loop insulin delivery was associated with comparable glucose control and significantly less hypoglycemia than SAP therapy. Larger, longer-duration multicenter trials are now indicated to determine clinical efficacy of closed-loop insulin delivery in T1D pregnancy and the impact on neonatal outcomes.
