In trying to get his land the farmer must consider the technical problem, economical and social the culture, the exploitation of agriculture always was linked with what will be produced, how many, here, when, how and where is distributed him. The utilization of the farmer's land as the production factor that was most important in the farming really was influenced by the relations kind between humankind and his land because will be related to in continuation of his farming. The land that was made an effort to get could take the form of his property personally or property of the other person. This research was aimed at identifying and analyzing the exploitation and institutional the agricultural land in rural areas. The method used was survey that was carried out in 12 Patanas villages that were spread in Lampung, West Java, Central Java, East Java, South Sulawesi, and NTB. In three villages, 25 farm households were selected. Results of the research showed the growth index reached 200 to 300, except in the paddy-field land where its irrigation was rotated and in dryland that was cultivated with cassava. The farmer used the superior variety seed, but did not yet apply balanced fertilizing. Fertilizing exceeded the recomendation whereas for other fertilizer (P05 and K20) and relative manure utilization was still under recommendation, in fact some farmers did not use. The productivity of the crop in the rainy season (rice and corn) higher was compared to dry season, except for the potato. Generally the farmer used capital personally, “YARNEN” system was an alternative that often was followed. The price of agricultural product was fluctuating in which the price of the dry season tended to be higher than in the rainy season, the status of the farmer was dominated by owner followed by the sharecropper and the leaser. The sharecropper and the leaser always did not come from the group landless because of the owner, also entered the rented market and sharecropper. The rented system that more stressed the aspect of economics than social more prominent in production centers of the potato. Key word: farming, institutional the land, agroecosystem

OBJECTIVEThe purpose of this meta-analysis was to evaluate the impact of perioperative antiepileptic drug (AED) prophylaxis on short- and long-term seizure incidence among patients undergoing brain tumor surgery. It is the first meta-analysis to focus exclusively on perioperative AED prophylaxis among patients undergoing brain tumor surgery.METHODSThe authors searched PubMed/MEDLINE, Embase, Cochrane Central Register of Controlled Trials, clinicaltrials.gov, and the System for Information on Gray Literature in Europe for records related to perioperative AED prophylaxis for patients with brain tumors. Risk of bias in the included studies was assessed using the Cochrane risk of bias tool. Incidence rates for early seizures (within the first postoperative week) and total seizures were estimated based on data from randomized controlled trials. A Mantel-Haenszel random-effects model was used to analyze pooled relative risk (RR) of early seizures (within the first postoperative week) and total seizures associated with perioperative AED prophylaxis versus control.RESULTSFour RCTs involving 352 patients met the criteria of inclusion. The results demonstrated that perioperative AED prophylaxis for patients undergoing brain tumor surgery provides a statistically significant reduction in risk of early postoperative seizures compared with control (RR = 0.352, 95% confidence interval 0.130–0.949, p = 0.039). AED prophylaxis had no statistically significant effect on the total (combined short- and long-term) incidence of seizures.CONCLUSIONSThis meta-analysis demonstrates for the first time that perioperative AED prophylaxis for brain tumor surgery provides a statistically significant reduction in early postoperative seizure risk.

OBJECTIVEWorldwide disparities in the provision of surgical care result in otherwise preventable disability and death. There is a growing need to quantify the global burden of neurosurgical disease specifically, and the workforce necessary to meet this demand.METHODSResults from a multinational collaborative effort to describe the global neurosurgical burden were aggregated and summarized. First, country registries, third-party modeled data, and meta-analyzed published data were combined to generate incidence and volume figures for 10 common neurosurgical conditions. Next, a global mapping survey was performed to identify the number and location of neurosurgeons in each country. Finally, a practitioner survey was conducted to quantify the proportion of disease requiring surgery, as well as the median number of neurosurgical cases per annum. The neurosurgical case deficit was calculated as the difference between the volume of essential neurosurgical cases and the existing neurosurgical workforce capacity.RESULTSEvery year, an estimated 22.6 million patients suffer from neurological disorders or injuries that warrant the expertise of a neurosurgeon, of whom 13.8 million require surgery. Traumatic brain injury, stroke-related conditions, tumors, hydrocephalus, and epilepsy constitute the majority of essential neurosurgical care worldwide. Approximately 23,300 additional neurosurgeons are needed to address more than 5 million essential neurosurgical cases—all in low- and middle-income countries—that go unmet each year. There exists a gross disparity in the allocation of the surgical workforce, leaving large geographic treatment gaps, particularly in Africa and Southeast Asia.CONCLUSIONSEach year, more than 5 million individuals suffering from treatable neurosurgical conditions will never undergo therapeutic surgical intervention. Populations in Africa and Southeast Asia, where the proportion of neurosurgeons to neurosurgical disease is critically low, are especially at risk. Increasing access to essential neurosurgical care in low- and middle-income countries via neurosurgical workforce expansion as part of surgical system strengthening is necessary to prevent severe disability and death for millions with neurological disease.
The subatlantic triangle: gateway to early localization of the atlantoaxial vertebral artery

Published: April 2018

OBJECTIVEExposure of the vertebral artery (VA) between C-1 and C-2 vertebrae (atlantoaxial VA) may be necessary in a variety of pathologies of the craniovertebral junction. Current methods to expose this segment of the VA entail sharp dissection of muscles close to the internal jugular vein and the spinal accessory nerve. The present study assesses the technique of exposing the atlantoaxial VA through a newly defined muscular triangle at the craniovertebral junction.METHODSFive cadaveric heads were prepared for surgical simulation in prone position, turned 30°–45° toward the side of exposure. The atlantoaxial VA was exposed through the subatlantic triangle after reflecting the sternocleidomastoid and splenius capitis muscles inferiorly. The subatlantic triangle was formed by 3 groups of muscles: 1) the levator scapulae and splenius cervicis muscles inferiorly and laterally, 2) the longissimus capitis muscle inferiorly and medially, and 3) the inferior oblique capitis superiorly. The lengths of the VA exposed through the triangle before and after unroofing the C-2 transverse foramen were measured.RESULTSThe subatlantic triangle consistently provided access to the whole length of atlantoaxial VA. The average length of the VA exposed via the subatlantic triangle was 19.5 mm. This average increased to 31.5 mm after the VA was released at the C-2 transverse foramen.CONCLUSIONSThe subatlantic triangle provides a simple and straightforward pathway to expose the atlantoaxial VA. The proposed method may be useful during posterior approaches to the craniovertebral junction should early exposure and control of the atlantoaxial VA become necessary.
Unsupervised Learning for Monaural Source Separation Using Maximization–Minimization Algorithm with Time–Frequency Deconvolution †
Authors: Woo Wai Lok , Gao Bin , Bouridane Ahmed , Ling Bingo Wing-Kuen , Chin Cheng Siong 
Published: April 2018

This paper presents an unsupervised learning algorithm for sparse nonnegative matrix factor time–frequency deconvolution with optimized fractional β -divergence. The β -divergence is a group of cost functions parametrized by a single parameter β . The Itakura–Saito divergence, Kullback–Leibler divergence and Least Square distance are special cases that correspond to β = 0 , 1 , 2 , respectively. This paper presents a generalized algorithm that uses a flexible range of β that includes fractional values. It describes a maximization–minimization (MM) algorithm leading to the development of a fast convergence multiplicative update algorithm with guaranteed convergence. The proposed model operates in the time–frequency domain and decomposes an information-bearing matrix into two-dimensional deconvolution of factor matrices that represent the spectral dictionary and temporal codes. The deconvolution process has been optimized to yield sparse temporal codes through maximizing the likelihood of the observations. The paper also presents a method to estimate the fractional β value. The method is demonstrated on separating audio mixtures recorded from a single channel. The paper shows that the extraction of the spectral dictionary and temporal codes is significantly more efficient by using the proposed algorithm and subsequently leads to better source separation performance. Experimental tests and comparisons with other factorization methods have been conducted to verify its efficacy.

Abstract
Based on observations from the FourStar near-infrared camera on the 6.5 m Baade-Magellan telescope at Las Campanas, Chile, we present calibrations of the JHK luminosities of stars defining the tip of the red giant branch (TRGB) in the halo of the Local Group dwarf galaxy IC 1613. We employ metallicity-independent (rectified) T-band magnitudes—constructed using J-, H-, and K-band magnitudes and both (J − H) and (J − K) colors to flatten the upward-sloping red giant branch tips as otherwise seen in their apparent color–magnitude diagrams. We describe and quantify the advantages of working at these particular near-infrared wavelengths, which are applicable to both the Hubble Space Telescope (HST) and the James Webb Space Telescope (JWST). We also note that these same wavelengths can be accessed from the ground for an eventual tie-in to Gaia for absolute astrometry and parallaxes to calibrate the intrinsic luminosity of the TRGB. Adopting the color terms derived from the IC 1613 data, as well as the zero points from a companion study of the Large Magellanic Cloud, whose distance is anchored to the geometric distances of detached eclipsing binaries, we find a true distance modulus of 24.32 ± 0.02 (statistical) ±0.05 mag (systematic) for IC 1613, which compares favorably with the recently published multi-wavelength, multi-method consensus modulus of 24.30 ± 0.05 mag by Hatt et al.
Measuring the Progenitor Masses and Dense Circumstellar Material of Type II Supernovae
Authors: Morozova Viktoriya , Piro Anthony L. , Valenti Stefano 
Published: April 2018

Abstract
Recent modeling of hydrogen-rich Type II supernova (SN II) light curves suggests the presence of dense circumstellar material (CSM) surrounding the exploding progenitor stars. This has important implications for the activity and structure of massive stars near the end of their lives. Since previous work focused on just a few events, here we expand to a larger sample of 20 well-observed SNe II. For each event we are able to constrain the progenitor zero-age main-sequence (ZAMS) mass, explosion energy, and the mass and radial extent of the dense CSM. We then study the distribution of each of these properties across the full sample of SNe. The inferred ZAMS masses are found to be largely consistent with a Salpeter distribution with minimum and maximum masses of 10.4 and 22.9 M
⊙, respectively. We also compare the individual ZAMS masses we measure with specific SNe II that have pre-explosion imaging to check their consistency. Our masses are generally comparable to or higher than the pre-explosion imaging masses, potentially helping ease the red supergiant problem. The explosion energies vary from (0.1–1.3) × 1051 erg, and for ∼70% of the SNe we obtain CSM masses in the range between 0.18 and 0.83 M
⊙. We see a potential correlation between the CSM mass and explosion energy, which suggests that pre-explosion activity has a strong impact on the structure of the star. This may be important to take into account in future studies of the ability of the neutrino mechanism to explode stars. We also see a possible correlation between the CSM radial extent and ZAMS mass, which could be related to the time with respect to explosion when the CSM is first generated.
Comet C/2011 W3 (Lovejoy) between 2 and 10 Solar Radii: Physical Parameters of the Comet and the Corona

Published: April 2018

Abstract
Comet C/2011 W3 (Lovejoy) is the first sungrazing comet in many years to survive perihelion passage. We report ultraviolet observations with the Ultraviolet Coronagraph Spectrometer (UVCS) spectrometer aboard the Solar and Heliospheric Observatory satellite at five heights as the comet approached the Sun. The brightest line, Lyα, shows dramatic variations in intensity, velocity centroid, and width during the observation at each height. We derive the outgassing rates and the abundances of N, O, and Si relative to H, and we estimate the effective diameter of the nucleus to be several hundred meters. We consider the effects of the large outgassing rate on the interaction between the cometary gas and the solar corona and find good qualitative agreement with the picture of a bow shock resulting from mass loading by cometary neutrals. We obtain estimates of the solar wind density, temperature, and speed, and compare them with predictions of a global magnetohydrodynamic simulation, finding qualitative agreement within our uncertainties. We also determine the sublimation rate of silicate dust in the comet’s tail by comparing the visible brightness from the Large Angle Spectroscopic Coronagraphs with the Si iii intensity from UVCS. The sublimation rates lie between the predicted rates for olivines and pyroxenes, suggesting that the grains are composed of a mixture of those minerals.
The Effects of Preceptor Training on New Graduate Registered Nurse Transition Experiences and Organizational Outcomes
Authors: Piccinini Carina J. , Hudlun Nancy , Branam Karen , Moore Jill M. 
Published: April 2018

Background:
New graduate RNs (NGRNs) may experience difficulties in their transition to independent practice. The main role of preceptors is to guide, validate, and supervise the care that NGRNs provide. However, preceptors may not receive training to serve in the role.

Method:
A literature review of the past 5 years was conducted, with 10 articles meeting the inclusion criteria to analyze the effects of preceptor training on NGRN outcomes.

Results:
Ten studies indicated a range of positive effects of preceptor training on NGRN transition experiences and organizational outcomes, including critical thinking and retention. Findings on NGRNs' stress levels are contradictory and ambiguous.

Conclusion:
A variety of positive outcomes can be realized for NGRNs who partner with formally trained preceptors.

Factors Influencing Registered Nurses' Perceptions of Their Professional Identity: An Integrative Literature Review
Authors: Rasmussen Philippa , Henderson Ann , Andrew Nicky , Conroy Tiffany 
Published: April 2018

Background:
This review synthesizes contemporary research investigating the factors influencing RNs' perceptions of their professional identity.

Method:
The method used was an integrative literature review.

Results:
Factors influencing RNs' perceptions of their professional identity were synthesized into three categories: the self, the role, and the context. The self is the nurse who enacts the role in practice, and the context is the practice setting. Poor alignment of these categories leads to stress, tension, and uncertainty affecting work-force retention. Strong alignment leads to satisfaction with the nursing role, increased staff retention, and improved quality of care and patient outcomes. These three categories should be considered when planning nursing professional development activities.

Conclusion:
This integrative review identified a lack of research addressing how nurses' perceptions of their professional identity change over time. A deeper understanding of their perspective is needed to establish whether career longevity and continued professional development are influences.
