Evaluating Instrument Quality: Rasch Model – Analyses of Post Test of Curriculum 2013 Training
Authors: Komalasari
Published: April 2020

The main purpose of this study was to evaluate the quality of post test utilized by LPMP Central Kalimantan Indonesia in curriculum 2013 training for X grade teachers. It uses Rasch analysis to explore the item fit, the reliability ( item and person), item difficulty, and the Wrigh map of post test. This study also applies Classical Test Teory (CTT) to determine item discrimination and distracters. Following a series of iterative Rasch analyses that adopted the “data should fit the model” approach, 30 items post test of curriculum 2013 training was analyzed using Acer Conquest 4 software, software based on Rasch measurement model. All items of post test of curriculum 2013 training are sufficient fit to the Rasch model. The difficulty levels (i.e. item measures) for the 30 items range from –1.746 logits to +1.861 logits. The item separation reliability is acceptable at 0.990 and person separation reliability is low at 0.485. The wright map indicates that the test is difficult for the teachers or the teachers have low ability in knowledge of curriculum 2013. The post test items cannot cover all the ranges of the teachers’ ability levels. Items discrimination of post test of curriculum 2013 training grouped into fair discrimination (item 2, 4, 5, 8, 11, 18) and poor discrimination (1, 3, 6, 7, 9, 10,12, 13, 14, 15, 16, 17, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30). Some distracters from item 1, 2, 6, 7, 8, 9, 11, 13, 16, 17, 18, 19, 20, 22, 24, 25, 27, 28, 29 and 30 are problematic. These distracters require further investigation or revision.

Published: April 2020

Предметом наукової статті є форми кооперації в бізнесі. Метою статті є аналіз, систематизація та узагальнення наявних теоретичних положень щодо сучасних форм кооперації в бізнесі. Дослідження проводилося з використанням системного підходу, наукових методів аналізу та синтезу. Результатами проведеного дослідження є узагальнення наявних форм кооперації в бізнесі та їх систематизація в єдину класифікацію. Авторами розглянуто передумови зростання процесів кооперування між окремими незалежними організаціями. Виділено такі ознаки кооперації, як взаємодія на добровільних засадах; наявність у кожної організації стратегічних цілей, які можуть бути досяжними вірогідніше під час кооперування; підвищення ефективності та стійкості бізнесу як очікуваний результат взаємодії; наявність довіри між партнерами; рівноправність та незалежність партнерів; наявність укладених угод, які визначають форму взаємозв’язків; отримання синергетичного ефекту від співпраці. У статті надано авторське визначення та викладено власне розуміння коопераційного процесу. Авторами надано зведену класифікацію організаційних форм кооперації в бізнесі залежно від виду діяльності, на розвиток якої вона спрямована. Такими видами діяльності авторами вибрано продажі, просування, виробництво, науково-дослідні та дослідно-конструкторські роботи (НДДКР), інноваційну діяльність. В результаті дослідження виявлено, що більшість кооперацій у сучасному бізнесі спрямована на розвиток інноваційної діяльності, яка є невід’ємною частиною економіки знань. Серед них слід назвати стратегічні альянси, кластери, інноваційні мережі та бізнес-екосистеми. Головну причину таких кооперацій автори вбачають у формуванні глобальної економіки знань, у якій знання є найважливішим ресурсом та головним джерелом конкурентних переваг. В подальшому авторами як інструмент стратегічного аналізу для вибору стратегії кооперації та управління знаннями, а також організаційної форми кооперації запропоновано використовувати модель обміну ресурсами між партнерами С. Паріса та Дж.К. Хендерсона. Залежно від рівня прихованості, специфічності та складності ресурсів у представленій авторами статті матриці вибираються стратегія надання ресурсів партнеру, стратегія об’єднання, стратегія розвитку інтелектуального потенціалу та стратегія використання знань партнера.

Published: April 2020

У статті розглянуто економіко-правову систему захисту комп’ютерних технологій України та Сполучених Штатів Америки. Виявлено, що США є першою державою, що розпочала охороняти комп’ютерні програми як об’єкт авторського права. Встановлено, що внесок ІТ-сфери у валовий внутрішній продукт (ВВП) країни за 7 років збільшився в 4 рази: з 1% у 2012 році до 4% у 2018 році. У ході аналізу світового ринку програмного забезпечення визначено частку українського ринку надання послуг в ІТ-сфері. Розглянуто видову характеристику комерціалізації програмного забезпечення України. Досліджено, що основними партнерами України за експортом ІТ-сфери є США (31%), Велика Британія (23%) та інші (46%), зокрема Німеччина, Канада, Ізраїль, Швеція, Швейцарія. Проаналізовано обсяги інвестицій на розвиток ІТ-сфери України, що склали в загальному обсязі у 2016 році 120 млн. дол., у 2017 році – 265 млн. дол., у 2018 році – 295 млн. дол. Проаналізовано попит на українські аутсорсингові компанії, які забезпечують патентно-ліцензійну діяльність на підприємствах як у своїй країні, так і поза її межами. У 2018 році 12 українських компаній та 6 компаній з українськими представниками увійшли в топ-100 лідерів за рейтингом “The 2018 Global Outsourcing 100”. Хоча український ринок має позитивну динаміку щодо експорту продуктів програмного забезпечення, все ще українські фірми не мають значної кількості замовлень на міжнародному ринку. У ході дослідження Асоціації виробників програмного забезпечення було встановлено, що в Україні лише 20% ліцензійного програмного забезпечення, інші 80% не мають потрібних ліцензій, тобто є нелегальними. Запропоновано вдосконалити чинне законодавство України щодо охорони об’єктів інтелектуальної власності у сфері комп’ютерних технологій, що дасть змогу не лише запобігти численним правопорушенням незаконного використання комп’ютерних програм, але й забезпечити значний розвиток країни у сфері комп’ютерних технологій загалом та збільшити можливості держави посісти почесне місце в Європейському Союзі серед експортерів комп’ютерних технологій.

Towards the total synthesis of chondrochloren A: synthesis of the (Z)-enamide fragment
Authors: Geldsetzer Jan , Kalesse Markus
Published: April 2020

The stereoselective synthesis of the (Z)-enamide fragment of chondrochloren (1) is described. A Buchwald-type coupling between amide 3 and (Z)-bromide 4 was used to generate the required fragment. The employed amide 3 comprising three chiral centers was obtained through a seven-step sequence starting from ᴅ-ribonic acid-1,4-lactone. The (Z)-vinyl bromide 4 is accessible in four steps from 4-hydroxybenzaldehyde. The pivotal cross coupling between both fragments was achieved after extensive experimentation with copper(I) iodide, K2CO3 and N,N′-dimethylethane-1,2-diamine.

Published: April 2020

This paper describes the synthesis of a series of organic liquid crystals (LCs) containing selectively fluorinated cyclopropanes at their termini. The syntheses used difluorocarbene additions to olefin precursors, an approach which proved straightforward such that these liquid crystal candidates could be efficiently prepared. Their physical and thermodynamic properties were evaluated and depending on individual structures, they either displayed positive or negative dielectric anisotropy. The study gives some guidance into effective structure–property relationships for the design of LCs containing selectively fluorinated cyclopropane motifs.

Pendidikan Islam di Era Globalisasi: Antara Potensi, Keunggulan, dan Tantangan
Authors: Rozi Bahru
Published: April 2020

Pendidikan Islam yang dahulu dianggap sebelah mata dan kurang diperhitungkan, namun saat ini dianggap satu-satunya pendidikan yang solutif bagi masyarakat modern. Berbagai persoalan yang terjadi di era global seperti saat ini, semakin lama semakin kompleks dan cenderung bertambah berat. Pendidikan dan lembaga pendidikan sekuler tidak mampu memberikan solusi alternatif untuk memecahkan berbagai persoalan tersebut. Sehingga masyarakat modern pun melirik kembali ke pendidikan agama Islam. Dengan konsep yang sangat jelas serta terarah, pendidikan Islam dan lembaganya bagaikan magnet yang sangat kuat daya tariknya. Pendidikan Islam mampu menarik minat masyarakat untuk menyerahkan pendidikan anak-anaknya di lembaga-lembaga pendidikan Islam. Namun, mampukah lembaga pendidikan Islam memanfaatkan peluang tersebut dengan baik? Ketersediaan SDM yang terbatas, kekurangan pembiayaan untuk sarana dan prasarana yang sangat besar adalah contoh kecil dari persoalan-persoalan yang dihadapi oleh sebagian besar lembaga-lembaga pendidikan Islam.

Authors: Mahmudah Umi
Published: April 2020

Dalam pendidikan, kurikulum merupakan jantung dari sebuah lembaga pendidikan yang di dalamnya memuat bagaimana proses perencanaan, pelaksanaan, dan evaluasi hasil proses pembelajaran. Namun kurikulum yang berkembang di Indonesia merupakan adopsian dari berbagai macam model kurikulum dan juga sering mengalami pergantian kurikulum. Hal ini tentu saja membuat berbagai jenis sekolah baik sekolah umum maupun sekolah yang berbasis agama atau madrasah tidak mempunyai prinsip kurikulum yang sesuai dengan nilai-nilai Keislaman. Oleh karena itu artikel ini telah membahas tentang kurikulum pendidikan dalam Kajian Tematik Al-Qur’an Hadits, dalam aspek ontologi, epistemolgi dan aksiologi sehingga akan cocok digunakan di lembaga pendidikan madrasah.

Dalam aspek ontologi telah dibahas secara detil pengertian kurikulum itu sendiri dari mulai etimologi sampai secara terminologi. Pada aspek epistemologi kita mengetahui bagaimana Al-Qur’an telah mengajarkan kita cara-cara/metode mengajar kepada peserta didik. Dan juga dibahas tentang bagaimana penerapan kurikulum pendidikan pada masa Rasulullah dan contoh penerapan kurikulum di masa sekarang

Published: April 2020

It is well known that organic waste materials deteriorate the performance of concrete. The impregnation of organic aggregates and their application in combination with other chemical admixtures and mineral additives are used in order to improve the concrete properties in case of their modification by organic components. The current research is focused on the evaluation of impact of multi-walled carbon nanotubes (MWCNT) on the properties of cement systems prepared based on wood sawdust extract (WSE). The setting time, density, consistency, flexural and compressive strength, water absorption tests were undertaken. The retardation effect of (WSE) on the initial and final setting time of cement paste was observed. The additional modification of cement paste with WSE by MWCNT in the dosage of 0.005% by weight of cement (bwoc) did not show the significant changes in initial and final setting time. The application of MWCNT in the dosage of 0.005% bwoc contributed to the increase of early strength of cement mortar prepared with WSE.

Published: April 2020

Early-type stars are short lived and scarce in comparison with other types. Based on the recently released catalogs of early-type stars from the largest Large Sky Area Multi-Object Fiber Spectroscopic Telescope spectroscopic survey, the intrinsic colors of the stars with effective temperature up to 32,000 K are determined for the bands from ultraviolet to infrared using the blue-edge method. Analytic relations are derived for the intrinsic color index with the effective temperature for the Wide-field Infrared Survey Explorer, Two Micron All Sky Survey, Gaia, AAVSO Photometric All-Sky Survey, Sloan Digital Sky Survey, the Panoramic Survey Telescope and Rapid Response System 1, and Galaxy Evolution Explorer bands. The results are generally consistent with previous works. In addition, the intrinsic colors of O-type dwarfs and OB supergiants are roughly estimated.
Constraining Short Gamma-Ray Burst Jet Properties with Gravitational Waves and Gamma-Rays
Authors: Biscoveanu Sylvia , Thrane Eric , Vitale Salvatore
Published: April 2020

Gamma-ray burst (GRB) prompt emission is highly beamed, and understanding the jet geometry and beaming configuration can provide information on the poorly understood central engine and circumburst environment. Prior to the advent of gravitational-wave astronomy, astronomers relied on observations of jet breaks in the multiwavelength afterglow to determine the GRB opening angle, since the observer’s viewing angle relative to the system cannot be determined from the electromagnetic data alone. Gravitational-wave observations, however, provide an independent measurement of the viewing angle. We describe a Bayesian method for determining the geometry of short GRBs (sGRBs) using coincident electromagnetic and gravitational-wave observations. We demonstrate how an ensemble of multimessenger detections can be used to measure the distributions of the jet energy, opening angle, Lorentz factor, and angular profile of sGRBs; we find that for a population of 100 such observations, we can constrain the mean of the opening angle distribution to within 10° regardless of the angular emission profile. Conversely, the constraint on the energy distribution depends on the shape of the profile, which can be distinguished.

configurations in Mn xi (Fe xii, Co xiii, and Ni xiv) is provided. The comparison between calculated excitation energies for the n = 4 states and available experimental values for Fe xii indicate that the calculations are highly accurate, with uncertainties of only a few hundred cm−1. Lines from these states are prominent in the soft X-rays. With the present calculations, several recent new identifications are confirmed. Other identifications involving

levels in Fe xii that were found to be questionable are discussed and a few new assignments are recommended. As some n = 4 states of the other ions also show large discrepancies between experimental and calculated energies, we reassess their identification. The present study provides highly accurate atomic data for the n = 4 states of P-like ions of astrophysical interest, for which experimental data are scarce.

Authors: Daniels Katherine
Published: April 2020

Charlotte has just finished recounting her unshakable depressive symptoms. In response to the nurse's inquiry, she struggles with the task of defining her goals for the next month. Tears form on her lower eyelashes as she whispers, “Goals. I'm not sure. My husband does all the planning...if he's talking to me. He hasn't spoken to me for the past week, not a word. I guess I'm lucky he let me come here today.” Patiently waiting for Charlotte to voice a goal, the nurse considers a tentative treatment plan, confident that depression is a treatable illness. However, will the nurse assess Charlotte for violence in the home? Is the nurse aware of the potentially lethal danger signs of comorbid intimate partner violence and major depression?

Published: April 2020

It is well known that stress has a profoundly negative impact on the physical, mental, and spiritual health of nurses. In addition, undergraduate nursing students experience a tremendous amount of stress as a result of their academic and clinical requirements. In the current study, new self-care activities were introduced in an undergraduate psychiatric–mental health nursing course at a midsize, teaching-intensive university over the course of four academic semesters. Thematic analysis was conducted using qualitative feedback from 79 students who completed standard university course evaluations, and four major themes emerged:
Stress Levels
,
Use of Self-Care Strategies and Coping Skills
,
Self-Reflection
, and

Authors: Almony Arghavan , Dhalla Mandeep Singh , Shah Gaurav K.
Published: April 2020

The authors report optical coherence tomography (OCT) findings of a hypertensive woman with retinal arterial macroaneurysm who noted sudden decreased vision in the left eye. Fluorescein angiography and OCT confirmed a diagnosis of retinal arterial macroaneurysm with macular hemorrhage, delineating the sub-internal limiting membrane and subretinal location of the hemorrhage. She subsequently underwent surgical displacement of the hemorrhage. OCT may be a useful imaging tool for evaluation and guidance of treatment in a hemorrhage involving the macula in retinal arterial macroaneurysm, diabetic retinopathy, and Terson's syndrome.
Compassion Fatigue Among RNs Working in Skilled Nursing Facilities
Authors: Steinheiser Marlene M. , Crist Janice D. , Shea Kimberly D.
Published: April 2020

Nurses employed in skilled nursing facilities (SNFs) are at risk for developing compassion fatigue. Compassion fatigue negatively impacts patient outcomes and is associated with decreased quality of care. Some nurses leave the profession due to compassion fatigue. There are no published studies in the United States focused on compassion fatigue among SNF nurses. The purpose of this interpretive phenomenological study was to identify the shared meanings of compassion fatigue among RNs caring for residents in SNFs. Shared meanings among participants were identified as: (1) I feel conflicted, which causes my compassion fatigue; (2) I feel physical and emotional manifestations of compassion fatigue; (3) Compassion fatigue is infused in every aspect of my life; and (4) We are trying to cope with compassion fatigue. Of paramount importance was the desire to make a difference in the lives of residents. Three participants sought employment outside the SNF setting due to compassion fatigue. Further research and education are needed to improve knowledge, policy, and practice. [

Published: April 2020

Platinum (Pt) is widely used as anode catalyst for direct ethanol fuel cell (DEFC) but toxic CO gas was produced in the system. Pt bimetallic catalysts can increase the reaction rate, current density and reduce CO gas production. However, some bimetallic catalysts are still expensive and give the low reaction rate. Trimetallic catalysts on carbon supporter were represented instead due to their better catalytic activities, long life time of operation and higher current density. In this study, we synthesized trimetallic alloy on N-doped reduced graphene oxide (NrGO) catalysts using as DEFC anode. The percentage of metals composition in the synthesized catalysts was varied. NrGO was prepared by Modified Hummers Method, then reduced by annealing under Nitrogen gas atmosphere and N-added by annealing with melamine. The preparation method for trimetallic alloy catalysts on NrGO was NaBH4 reduction. The X-ray diffraction (XRD) patterns displayed their alloy phase of PtMRu (M = Au, Sn) which compose of Pt main structure and NrGO supporter. Scanning Electron Microscopy (SEM) images showed the dispersion of alloy metal particles on NrGO surface. The composition of catalysts could be confirmed by Energy dispersive spectroscopy (EDS) data and the phase of alloy particles were verified by electron diffraction (SAD) patterns. Transmission Electron Microscopy (TEM) images showed the particle size of PtAuRu and PtSnRu in various specific percentage on NrGO. The approximate particle size for 10Pt2Au8Ru = 4.88±1.02 nm, 10Pt5Au5Ru = 58.45±42.16 nm, 10Pt8Au2Ru = 11.05±2.29 nm, 10Pt2Sn8Ru = 3.31±1.44 nm, 10Pt5Sn5Ru = 3.50±0.73 nm and 10Pt8Sn2Ru = 4.09±0.97 nm. Catalytic activity of these materials related to their particle size.

Authors: Kouropoulos Giorgos
Published: April 2020

The scope of the specific study is the statistical prediction of the annual carbon dioxide use emissions due to the operation of computed tomography (CT) scanners and magnetic resonance imaging (MRI) units in hospitals, health units and diagnostic centers, for the period between 2018 and 2030, in 120 countries across the world. The main sources of information for this study comprise statistical data from international organizations, scientific articles and measurements. The basic calculation tool of the study is a mathematical model, modified in such a way so that the calculations can be carried out using the available statistical data. In the final stage of the study, the functions that predict the carbon dioxide use emissions in relation to the years, will be extracted. Furthermore, all the errors and uncertainties of the mathematical model will be estimated. The conclusion, arising after implementation of the calculations, is that the carbon dioxide use emissions of CT scanners and MRI units are expected to grow by 30%, i.e., from 0.344 gigatonnes in 2018 to 0.497 gigatonnes in 2030.

Ceramic ware waste generation is becoming a global concern because of the increasing volume, hazardous nature, limited reusability, and poor waste management practices. This study examined the feasibility and efficacy of the inclusion of this waste as complementary aggregate in solid masonry unit production with bias interest on the compressive strength and water absorbability. Three particle sizes (1.4, 1.7, and 2.0 mm) of crushed ceramic ware waste were blended with natural fine aggregate under three different mix ratios (10, 20, and 30%) to produce the masonry units cured for 7, 14, 21, and 28 days prior to compressive tests analysis. Afterwards, some of the categories cured for 28-days were subjected to water absorption test. Morphology and elemental composition of the aggregates were also inspected using SEM-EDM machine. Also investigated were some of the aggregates’ physical properties. Results indicated that most of the waste-modified solid masonry units not only had water absorption capacity within required standard. The values were equally lower than the unmodified dense block (control) by 27 - 50%. Of the eighteen different categories produced, all M20T14, M20T21, and M30T28 modified dense masonry unit series with P1.7 (1.7 mm) and P2.0 (2.0 mm) particle sizes had high crushing force, compressive strength, and modulus range, which were 57 - 70 kN, 57 - 61 kN, 59 - 76 kN; 5.1 - 5.2 MPa, 5.1 - 5.5 MPa, 5.3 – 6.8 MPa; and 400 – 441 MPa, 411 – 419 MPa, 468 – 480 MPa respectively. Hence, modified masonry units with particle sizes P1.7 and P2.0 under the M20T14, M20T21, and M30T28 series are suitable masonry units for non-loading construction purposes. Interestingly, modified masonry unit (M30P2.0T7) cured under 7 days could also fit into this category. Hence, utilization of ceramic ware waste as co-aggregate in dense masonry units with M20 and M30 series production were established in this study for non-loading construction purposes

The functioning of passenger transport systems should provide necessary quality of passenger service. The results of this research have shown possibility to increase the quality of urban public transport via influence on the driver’s state due to the rational schedule planning. The state change patterns of drivers during the idle time on the final and intermediate bus stops were formalized, based on field observations. The following conclusion was made: decreasing of driver’s body stress takes place during the idle time on the route stops. The intensity of decreasing of driver’s body stress is inversely proportional to the meaning of activity index of driver’s regulatory systems before the start of standing time. Consequently, the duration of idle time must be differentiated depending on the value of the indicator of activity of driver’s regulatory systems before the start of standing time, which is influenced by the working conditions. ECG method was used for assessing driver’s fatigue in elements of transportation process. Comparative analysis of driver’s state changes during the different types of idle time shows the comparability of the results of the study. Transportation management experts can use the research results in urban transport schedule planning and monitoring.

Seasonality and inter-annual variation of the energy balance of natural surfaces as the effect of conversion from natural to agricultural areas has been the object of much in-depth research in South America. However, none has assessed the effect of conversion from a native to an urbanized area. Current research was performed in the city of Cuiabá, in the Cerrado-Pantanal ecotone, state of Mato Grosso, central Brazil, featuring a tropical sub-humid climate (Aw). The paper investigates the pattern of energy fluxes exchanges in the rural and urban sites located in Brazilian savannah ecosystem. The heat stored inside the urban canopy (ΔQS) and within the rural area was obtained by the Objective Hysteresis Model (OHM) and by soil flux meter, respectively. Sensible (H) and latent (LE) heat ﬂuxes were estimated by the Bowen Ratio Energy Balance (BREB). The rural and urban sites had different patterns in the micrometeorology variables Wind speed decreased and air temperature and vapor pressure deficit increased from rural to urban site. The urbanization also modified the energy fluxes partition of urban canopy by increasing ΔQs (12%) and H (60%) and by decreasing LE (29%), with β = 2.0 in contrast of rural canopy, where the partition was ΔQs (1.5%), H (29%), LE (64%) and β = 0.45. The ΔQS, H and LE were in phase with Rn, differing from what has been reported for sites in North America and Europe.
ADSORPTION KINETICS, ISOTHERMS, THERMODYNAMICS STUDIES ON THE REMOVAL OF CONGO RED DYE USING ANNONA SQUAMOSA (CUSTARD APPLE) PEEL
Authors: Agarwal Sarang , Vilvanathan Sowmya , S Shanthakumar
Published: April 2020

The present study evaluates the feasibility of an adsorbent prepared from Annona squamosa (custard apple) peel, in removing Congo red dye from its aqueous solution. Batch experiments were carried out to study the effect of various parameters like pH (2-8), adsorbent dose (0.005-0.5 g/100mL), contact time (5-120 min), initial dye concentration (25-200 mg/L) and temperature (298-308 K) to determine its effectiveness as an adsorbent. Maximum dye removal attained at pH 2, adsorbent dose 0.1 g/100mL in equilibrium time of 45 min at 308K. Adsorption kinetics using pseudo-first order and pseudo-second order models, and adsorption isotherm using Langmuir and Freundlich models were studied. The adsorption process was found to follow pseudo-second order kinetic model and more favourably described the Langmuir isotherm model. The Gibbs free energy was found to be negative, signifying the spontaneous nature of the adsorption process. Removal of Congo red dye from its aqueous solution by custard apple peel was found to be an endothermic process. The results of the present study suggest that custard apple can be effectively used as an adsorbent to remove Congo red dye from aqueous solution.
DEVELOPMENT OF A GIS-BASED COMPOSITE PUBLIC TRANSPORT ACCESSIBILITY INDEX
Authors: Cyril Anila , Mulangi Raviraj H , George Varghese
Published: April 2020

The increasing interest in sustainable modes of transport such as public transport has triggered the need for evaluation of accessibility to and from the transit service. Accessibility to the transit service determines the service attractiveness and hence better accessibility increases the demand. Although accessibility has been the focus of research in the past few decades, it still remains a concept that has been poorly defined and hence finding a theoretically good and operationally sound measure of accessibility is a challenging task. The objective of this paper is to develop a composite public transport accessibility index using Geographic Information System (GIS) as a case study of an Indian city, Trivandrum. This concept is a spatio-temporal GIS-based public transport accessibility model which includes travel modes of walking and bus transit, travel impedance and service coverage of the transit network. The methodology used in the study is based on the factor that the index should measure the accessibility which comes from proximity to bus stops and land use destinations and the proportion of the population served.
