Tropical climate–vegetation–fire relationships: multivariate evaluation of the land surface model JSBACH
Authors: Lasslop Gitta , Moeller Thomas , D'Onofrio Donatella , Hantson Stijn , Kloster Silvia
Published: October 2018

Abstract. The interactions between climate, vegetation and fire can strongly influence
the future trajectories of vegetation in Earth system models. We evaluate the
relationships between tropical climate, vegetation and fire in the global
vegetation model JSBACH, using a simple fire scheme and the complex fire
model SPITFIRE with the aim to identify potential for model improvement. We
use two remote-sensing products (based on MODIS and Landsat) in different
resolutions to assess the robustness of the obtained observed relationships.
We evaluate the model using a multivariate comparison that allows us to focus
on the interactions between climate, vegetation and fire and test the
influence of land use change on the modelled patterns.
Climate–vegetation–fire relationships are known to differ between
continents; we therefore perform the analysis for each continent separately. The observed relationships are
similar in the two satellite data sets, but maximum tree cover is reached at
higher precipitation values for coarser resolution. This shows that the
spatial scale of models and data needs to be consistent for meaningful
comparisons. The model captures the broad spatial patterns with regional
differences, which are partly due to the climate forcing derived from an
Earth system model. Compared to the simple fire scheme, SPITFIRE strongly
improves the spatial pattern of burned area and the distribution of burned
area along increasing precipitation. The correlation between precipitation
and tree cover is higher in the observations than in the largely climate-driven vegetation model, with both fire models. The multivariate comparison
identifies excessive tree cover in low-precipitation areas and a too-strong relationship between high fire occurrence and low tree cover for the
complex fire model. We therefore suggest that drought effects on tree cover
and the impact of burned area on tree cover or the adaptation of trees to
fire can be improved. The observed variation in the relationship between precipitation and maximum
tree cover between continents is higher than the simulated one. Land use
contributes to the intercontinental differences in fire regimes with SPITFIRE
and strongly overprints the modelled multimodality of tree cover with
SPITFIRE. The multivariate model–data comparison used here has several
advantages: it improves the attribution of model–data mismatches to model
processes, it reduces the impact of biases in the meteorological forcing on
the evaluation and it allows us to evaluate not only a specific target variable
but also the interactions.
The 4.2 ka BP event: multi-proxy records from a closed lake in the northern margin of the East Asian summer monsoon

Published: October 2018

Abstract. The 4.2 ka BP event has been widely investigated since it
was suggested to be a possible cause for the collapse of ancient
civilizations. With the growth of proxy records for decades, however, both
its nature and its spatial pattern have become controversial. Here we
examined multi-proxy data of the grain-size distribution, ostracode
assemblage, pollen assemblage, and the pollen-reconstructed mean annual
precipitation from a sediment core at Hulun Lake in northeastern Inner
Mongolia spanning the period between 5000 and 3000 cal. yr BP to identify
the nature and the associated mechanism of the 4.2 ka BP event occurring in
the monsoonal region of eastern Asia. Higher sand fraction contents,
littoral ostracode abundances, and Chenopodiaceae pollen percentages
together with lower mean annual precipitation reveal a significant dry
event at the interval of 4210–3840 cal. yr BP that could be a regional
manifestation of the 4.2 ka BP event in the northern margin of the East
Asian summer monsoon (EASM). We suggest that the drought would be caused by
a decline in the intensity of the EASM on millennial-to-centennial scales
that could be physically related to persistent cooling of surface waters in
the western tropical Pacific and the North Atlantic. The cooling of western
tropical Pacific surface waters could reduce moisture production over the
source area of the EASM, while the cooling of North Atlantic surface waters
could suppress northward migrations of the EASM rain belt, both leading to a
weakened EASM and thus decreased rainfall in the northern margin of the
EASM.
Comparing the spatial patterns of climate change in the 9th and 5th millennia B.P. from TRACE-21 model simulations
Authors: Ning Liang , Liu Jian , Bradley Raymond S. , Yan Mi
Published: October 2018

Abstract. The spatial patterns of global temperature and precipitation changes, as well as corresponding large-scale circulation patterns during the latter part of the 9th and 5th millennia B.P. (4800–4500 versus 4500–4000 years B.P. and 9200–8800 versus 8800–8000 years B.P.) are compared through a group of transient simulations using Community Climate System Model version 3 (CCSM3). Both periods are characterized by significant sea surface temperature decreases over the North Atlantic south of Iceland. Temperatures were also colder across the northern hemisphere, but warmer in the southern hemisphere. Significant precipitation decreases are seen over most of the northern hemisphere, especially over Eurasia and the Asian monsoon regions, indicating a weaker summer monsoon. Large precipitation anomalies over northern South America and adjacent ocean regions are related to a southward displacement of the Inter Tropical Convergence Zone (ITCZ). Climate changes in the late 9th millennium B.P. (The 8.2 ka B.P. event) are widely considered to have been caused by a large fresh water discharge into the northern Atlantic, which is confirmed in a meltwater forcing sensitivity experiment, but this was not the cause of changes occurring between the early and latter half of the 5th millennium B.P. We speculate that long-term changes in insolation related to precessional forcing led to cooling, which passed a threshold around 4500 years B.P., leading to a reduction in the Atlantic meridional overturning circulation (AMOC) and associated teleconnections across the globe. The onset of the Neoglacial occurred around this time, and the subsequent changes in glacierization have persisted, modulated by internal centennial-scale ocean-atmosphere variability. We suggest that the 4.2 ka B.P. event was one of several late Holocene multi-century fluctuations that were embedded in a longer-term, lower frequency change in climate, linked to orbital forcing.
FVM 1.0: A nonhydrostatic finite-volume dynamical core
formulation for IFS

Published: October 2018

Abstract. We present a nonhydrostatic finite-volume global atmospheric model formulation for numerical weather prediction with the Integrated Forecasting System (IFS) at ECMWF, and compare it to the established operational spectral-transform formulation. The novel Finite-Volume Module of IFS (henceforth IFS-FVM) integrates the fully compressible equations using semi-implicit time stepping and non-oscillatory forward-in-time (NFT) Eulerian advection, whereas the spectral-transform IFS solves the hydrostatic primitive equations (optionally the fully compressible equations) using a semi-implicit semi-Lagrangian scheme. The IFS-FVM complements the spectral-transform counterpart by means of the finite-volume discretisation with a local communication footprint, fully conservative and monotone advective transport, all-scale deep-atmosphere fully compressible equations in a generalised height-based vertical coordinate, applicable on flexible meshes. Nevertheless, both the finite-volume and spectral-transform formulations can share the same quasi-uniform horizontal grid with co-located arrangement of variables, geospherical longitude-latitude coordinates, and physical parametrisations, thereby facilitating their comparison, coexistence and combination in IFS. We highlight the advanced semi-implicit NFT finite-volume integration of the fully compressible equations of the novel IFS-FVM considering comprehensive moist-precipitating dynamics with coupling to the IFS cloud parametrisation by means of a generic interface. These developments – including a new horizontal-vertical split NFT MPDATA advective transport scheme, variable time stepping, effective preconditioning of the elliptic Helmholtz solver in the semi-implicit scheme, and a computationally efficient coding implementation – provide a basis for the efficacy of IFS-FVM and its application in global numerical weather prediction. Here, numerical experiments focus on relevant dry and moist-precipitating baroclinic instability at various resolutions. We show that the presented semi-implicit NFT finite-volume integration scheme on co-located meshes of IFS-FVM can provide highly competitive solution quality and computational performance to the proven semi-implicit semi-Lagrangian integration scheme of the spectral-transform IFS.
Technical note: Analytical sensitivity analysis and uncertainty estimation of a two-component hydrograph separation method which uses conductivity as a tracer
Authors: Yang Weifei , Xiao Changlai , Liang Xiujuan
Published: October 2018

Abstract. The conductivity two-component hydrograph separation method is cheap and easy to operate and is favored by hydrologists. This paper analyzes the sensitivity of the baseflow index (BFI, the long-term ratio of baseflow to streamflow) calculated by this method to errors or uncertainties of the two parameters (BFC, the conductivity of baseflow; ROC, the conductivity of surface runoff) and of the two variables (yk, the specific streamflow; Qck, the specific conductivity of streamflow), and then estimates the uncertainty of BFI. The analysis shows that when the time series is longer than 365 days, the random measurement errors of yk or Qck will cancel each other, and the influence on BFI can be neglected. Dimensionless sensitivity indices (the ratio of the relative error of BFI to the relative error of BFC or ROC) can well express the propagation of errors or uncertainties of BFC or ROC into BFI. Based on the sensitivity analysis, the uncertainty estimation method of BFI is derived. Representative sensitivity indices and BFI' uncertainties are yielded by application of the resulting equations to 24 watersheds in the United States. The results indicate that BFI is more sensitive to BFC, and the conductivity two-component hydrograph separation method may be more suitable for the long time series in a small watershed. After considering the mutual offset of the measurement errors of conductivity and streamflow, the uncertainty of BFI is reduced by half.
A Bayesian Approach to Multivariate Adaptive Localization in Ensemble-Based Data Assimilation with Time-Dependent Extensions
Authors: Popov Andrey A. , Sandu Adrian
Published: October 2018

Abstract. Ever since its inception, the Ensemble Kalman Filter has elicited many heuristic methods that sought to correct it. One such method is localization – the thought that nearby variables should be highly correlated with far away variable not. Recognizing that correlation is a time-dependent property, adaptive localization is a natural extension to these heuristics. We propose a Bayesian approach to adaptive Schur-product localization for the DEnKF, and extend it to support multiple radii of influence. We test both the empirical validity of (multivariate) adaptive localization, and of our approach. We test a simple toy problem (Lorenz '96), extending it to a multivariate model, and a more realistic geophysical problem (1.5 Layer Quasi-Geostrophic). We show that the multivariate approach has great promise on the toy problem, and that the univariate approach leads to improved filter performance for the realistic geophysical problem.

El repertorio musical como elemento posibilitador de un enfoque sociocrítico en Educación Primaria. Estudio del currículum impartido en el municipio de Valencia
Authors: Marín Liébana Pablo , Botella Nicolás Ana María
Published: October 2018

Este estudio constituye una primera aproximación analítica a una investigación más amplia cuyo objetivo es investigar el desarrollo del pensamiento sociocrítico en estudiantes de 5º y 6º de Educación Primaria a través de la utilización de un repertorio musical vinculado a contextos social y educativamente relevantes. Para ello, se ha analizado el repertorio musical utilizado y el grado de acuerdo e implementación del enfoque sociocrítico en los centros públicos de la ciudad de Valencia, aplicando un cuestionario a una muestra de n=80 maestros (N=92). Los resultados muestran un predominio en las aulas de la música clásico-romántica, escolar y folklórico-tradicional. Además, se demuestra que esta selección está condicionada por las representaciones de los maestros sobre la música. Por otra parte, la mayoría de estos coinciden con los principios del enfoque sociocrítico, pero pocos lo aplican.

Controversias entre la teoría curricular y la práctica educativa en la educación musical
Authors: Angel-Alvarado Rolando
Published: October 2018

La calidad de un sistema educativo se puede observar mediante la consistencia entre la teoría curricular y la práctica educativa. Particularmente, el currículo chileno expresa que la creatividad asume un rol esencial en la educación musical, tanto en los niveles de educación primaria como de secundaria. En este estudio, la creatividad se posiciona como la variable predictora del modelo, confirmándose estadísticamente la teoría curricular. Sin embargo, los hallazgos demuestran que las actividades creativas son escasamente potenciadas en las prácticas educativas, al punto que, a mayor nivel educativo, menor actividad creativa. En conclusión, no existe consistencia entre la teoría curricular y la práctica educativa. Por lo tanto, futuros estudios no deben centrarse en la confrontación entre docentes generalistas y especialistas porque tal enfoque solo minimiza el debate sobre las competencias pedagógicas.

This paper aims to examine the relationship between Ownership Structure Mechanisms (Managerial Ownership, Institutional Ownership, Block holder Ownership and Outside Director Ownership) and Investment Efficiency by using panel data analysis. To investigate this relationship used the multiple regression models. Findings of investigation of 35 firms listed on the Egyptian Stock Exchange in the period 2006 to 2015 by balanced Panel model representative. Results indicated that Managerial Ownership isn’t related with investment efficiency. In contract, institutional ownership, block holder ownership and outside director ownership have a negative relationship with investment efficiency. In addition, the researcher found that control variables (Firm size, Debt ratio, Tobin’s Q) not related to investment efficiency. These findings imply that the Majority of Egyptians firms relies on institutional without individual ownership and then reduces much of possible from agency problems and decreasing information asymmetry and facilitating the monitoring of investment decisions.
Citizen Sociolinguistics: Making Connections in the Foreign Language Classroom
Authors: Jung Ji-Young , Lee Eunji
Published: October 2018

The current study explores implementing the Connections Standards in language curriculum. To foster learners' critical thinking abilities, we suggest engaging students in interpreting and analyzing information available in open-source media. In our experiment in a fourth-year Korean class at a university in the northeastern United States, as “citizen sociolinguists,” students carried out a sociolinguistic exploration on Korean language uses in a wide array of Internet-based media and share their interpretation of their social meanings. The data come from the students' final presentations, which covered a range of sociolinguistic issues such as Konglish, neologism (word coinage), and gendered speech. The results showed that students applied their critical thinking skills to analyzing various language uses in contemporary Korean and developed informed perspectives on diverse sociolinguistic issues.

This study aims to identify the disclosure level of corporate social responsibility CSR in the financial reports of Jordanian pharmaceutical Public shareholding companies listed at Amman Stock Exchange (ASE), and to achieve this goal, researchers studied number of CSR elements, which can be represented in employees, society, product, power, and the environment, where the sample consisted of all (11) Jordanian pharmaceutical companies listed at ASE, which have data available in this financial market during the period (2014-2016). In order to achieve the objectives of the study, a CSR was built which consists of (26) factors, depending on a number of previous studies, laws, and annual financial reports of these companies. The study results found that overall ratio of the CSR amounted to approximately 46%, where the highest percentage of disclosure reached 69% and the lowest was 12%. The results also showed that different company size through (total assets) had nothing to do with the quality and level of CSR disclosure. The study recommended that companies should focus on their role in CSR from the inside, through the employee’s element, the need to focus on elements, such as occupational safety and health insurance, and to increase employee’s efficiency through training, and rehabilitation.

Characterisation of Arbequina Extra Virgin Olive Oil from Uruguay
Authors: Ellis Ana Claudia , Gambaro Adriana
Published: October 2018

Since the year 2002, the Uruguayan oil-producing sector has been growing at a steady peace, utilizing over 10,000 seeded hectares across the country. The aim of this study was to characterise both the chemical and sensory properties of the extra virgin olive oil variety known as Arbequina through two consecutive harvests. The work was carried out using olives with three different ripening indices; the oil was extracted using an Abencor system. The moisture of the olive, yield extraction, and yield on both a dry and wet basis were determined. The obtained oils were characterized by determining the free acidity, main antioxidant compounds (polyphenols and tocopherols), composition of fatty acids, and sensory profiles. Olive moisture was over 57%, which led to production of pomaces characterized as “difficult pastes”, explaining the low yield obtained. The harvest year and ripening index affected different parameters such as Abencor yield and, on a dry basis, the free acidity, polyphenolic content, oleic acid, and linoleic acid contents and fruity, bitter, and pungent intensities. To determine the best time of harvest, it is important to consider the balance between yield (which is significantly greater in olives with a ripening index above 3) and oil quality, as a higher ripening index decreases positive sensory attributes such as pungency and bitterness intensities.
Strategic challenges for Serbia's integration with the European Union

Published: October 2018

Serbia began the process of integration with the European Union in 2003. After eleven years
on a difficult road to the transformation of political and constitutional contexts, Serbia
gained the chance to become a member of the Community. On the path to accession to the
European Union, Serbia had to resolve some strategic challenges, of which the main one is
the problem of regulating the political status of Kosovo.

The aim of this article is to indicate the position of Serbia and Kosovo’s Albanians
regarding the dispute over the political status of Kosovo, as well as examine the process of
normalisation of relations between Serbia and Kosovo as a key mechanism for resolving
the dispute. The challenges emerging for Serbia as a result of the negotiation process will be
covered. The new dimension of Serbia’s cooperation with Russia will also be analysed as one
of the factors which may have a significant impact on the further dynamics of the process of
Serbia’s integration with the European Union.

Background. The purpose of this study is to describe the role of Platelet Rich Plasma in preventing tunnel enlargement in anterior cruciate ligament reconstruction with a hamstring autograft
Material and methods. Forty-four patients who underwent transtibial reconstructive surgery with a hamstring tendon autograft between March 2014 and July 2015 were included in this study. This study involved two groups. Group A consisted of 18 patients who underwent PRPadministration into the femoral and tibial tunnel. Group B was a control group that included 26 patients who underwent ACL reconstruction surgery with a hamstring autograft without PRP. The patients were evaluated preoperatively and postoperatively with the IKDC score, Lysholm score, Tegner activity scale and a KT-1000 arthrometer device. The diameter of the tibial and femoral tunnels of the operated knees was measured on the first day and at three months postoperatively using CT. Measurements carried out for tomography standardization of the patients were evaluated on coronal, sagittal and axial images from 64-slice MSCT scans.
Results. On comparison of radiological data between both groups, there was less tunnel enlargement in PRP-administered group for the femoral tunnel, but the result was not statistically significant. No difference was seen between clinical examination results and the grading scales used.
Conclusions. 1. The radiological findings of our study indicated that while there was less tunnel enlargement in the PRP group, there was no statistically significant difference between the groups. 2. Similarly, clinical exa­mination results and scoring scales used did not de­monstrate any intergroup difference. 3. As a result, we donot recommend routine use of PRP for the prevention of tunnel enlargement after ACL reconstruction.

Sugarcane is cultivated in almost all Brazilian agricultural regions, Brazil being the world's largest
producer, which requires breeding programs to create more productive and efficient varieties
adapted to each region. In sugarcane breeding programs there is a need, under certain
circumstances, to multiply the selected material rapidly. In this scenario, micropropagation
appears as an alternative to the conventional process of vegetative propagation through stalks.
The objective of this review was to describe the scenario on micropropagation research in
sugarcane, such as meristem culture, sugarcane calli, somatic embryogenesis, in vitro germplasm
conservation and cryopreservation. It has been observed in the literature that there is a wide
spectrum of use for the numerous and well established protocols for the in vitro manipulation of
sugarcane morphogenesis. The prospect of producing new features via induction of somaclonal
variation and in vitro experimentation for pest and disease tolerance has not yet been extensively
explored. While benefits of minimal growth are recognized in in vitro germplasm conservation of
elite sugarcane cultivars, and all positive potential of this technique and cryopreservation may still

The objective of this review is to conduct a survey on the main concepts related to dog and cat
nutrition in the different life stages. The market for pet products and services has been expanding
worldwide and is a lucrative new segment of the economy. Advances in research with pet
nutrition have occurred to meet a growing demand both for product innovation that catches the
attention of owners and animals, as well as for ensuring that nutritional requirements are met at
each age and a better quality of life. Dogs and cats present themselves as carnivores, but with
habits and food forms often classified as an omnivorous species, with carnivorous cats being strict
and dogs being facultative. Just like the human diet, dogs' health depends on a correct and
balanced diet that contains a broad set of nutrients to meet all daily needs. Functional foods
encompass both foods and ingredients that have the basic nutritional functions and also produce
metabolic and / or physiological health benefits. The addition of functional ingredients to dog and
cat foods is already a reality in the nutrition of pets. In addition, there are a variety of food
products for dogs and cats, being classified as dry, moist and semi-moist.

(without addition of oregano essential oil), Q1 (Addition of 0,01%) and Q2 (addition of 0,02%)
were produced. The water content, ash, total soluble solids, lactic acidity and lipolysis were
evaluated according to the Adolf Lutz Institute (2008). Data were submitted to ANOVA and Tukey
test (p ≤0,05). The samples were analyzed microbiologically (mesophilic aerobes, psychrotrophic,
total coliforms and the presence of salmonella) at times 0, 7, 14 and 21 days. The counts for the
mesophilic, psychrotrophic, coliform aerobic microorganisms and the absence of salmonella were
within the limits established by the legislation. Low counts demonstrate satisfactory hygiene
conditions as well as correct storage. This leads us to conclude that the insertion of enriched
cheeses of oregano essential oil in the consumer market is viable, at the concentrations evaluated.

CLONAGEM POR TRANSFERÊNCIA NUCLEAR EM BUBALINOS
Authors: Sousa Camargos Aline , Dantas Ariane
Published: October 2018

The success of core transfer (CT) depends on the origin of the donor cell, on the stage of
development of the recipient cytoplast and on the synchronization between the cell cycle of the
donor and recipient cells. The somatic nucleus must be reprogrammed after CT, thus restoring the
totipotent state, and then resuming cellular development. However, it is noted that the efficiency
of CT is still low, especially with a deficiency of the overall gene expression of the cloned embryo.
However, the number of species of cloned mammals has been increasing in the last years, being
this technique an important tool that does not aid in the effectiveness of buffalo reproduction.
Thus, this review focuses on the description of the main processes pertinent to this process, as
well as to analyze as future implications, as well as some factors that affect the success of nuclear
transfer.
ESTUDO SOBRE O USO CONSORCIADO DE ENERGIA SOLAR FOTOVOLTAICA COM
BIOMASSA EM GRANJAS DE FRANGO DE CORTE
Authors: Barbosa Matos Fernando
Published: October 2018

This paper proposes an analysis of the financial viability of the consortium use of photovoltaic solar
energy with the biomass produced from a biodigester. These two means of alternative energy
generation are suitable for use in chicken farms, reusing the chicken bed and allowing the producer
to diversify his production through the sale of biofertilizer produced on the farm. This revenue
complement is what makes the enterprise viable, making the internal rate of return higher than
the minimum rate of attractiveness.

In animal breeding, new methodologies can be applied in statistical analysis to improve the
genetic evaluation and, for this reason, they have been the subject in several studies. In the last
years, several research works have intended the model development with more adjustable
functions to the distinct variables. A set of functions known as Spline functions has called the
attention of researches. Then, the purpose of this review is to discuss the use of Spline functions
that are applied to growth data in animal breeding. Splines are segmented regression functions
that are united by points known as joint points and have the ability to improve the curvature of
models and, therefore, the function adjustment. These functions have interesting properties such
as the interpolatory nature, less multicolinearity problems, parameter linearity and the ability of
increasing the approximation domain, all of which provide estimates in a wide range of possible
values. There are three types of Spline functions: natural spline functions, smoothing spline

functions or nonparametric regression and B-splines functions. These latter functions are more
applied to animal breeding, mainly as alternatives to random regression models (RRM) that use
the Legendre polynomials. The matrices formed by RRMs with the use of B-spline functions or
Legendre polynomials are more scarce and easier to be inverted. Then, the use of Spline functions
has been more intensified in the last years because studies have had the purpose of improving the
adjustment with less model parameters in functions. New studies will allow improving the
methodology and finding out new applications to the Spline functions.
Format Shift: Information Behavior and User Experience in the Academic E-book Environment
Authors: Tracy Daniel G.
Published: October 2018

This article seeks to understand information behavior in the context of the academic e-book user experience, shaped by a disparate set of vendor platforms licensed by libraries. These platforms vary in design and affordances, yet studies of e-book use in an academic context often treat e-books as a unified phenomenon in opposition to print books. Based on participant diaries tracking e-book information behavior and follow-up interviews and focus groups on troubleshooting and format shifting behaviors, this study seeks to provide a deep qualitative look at decisions that academic users make about formats when encountering e-books. It identifies reasons for noted disparities between stated user preferences for print books while often using e-books instead. It also demonstrates the importance of considering e-books as a set of formats, rather than a unified experience, when evaluating e-book platforms or providing information services around a set of platforms. While e-book studies often point to a distinction between “use” of e-books and “reading” of print books by users, this study shows much more willingness to both use and read e-books for some tasks if platforms allow for offloading reading of content to preferred reading devices and apps. This has implications for collection development, advocacy with vendors, and for marketing to or consulting with users about e-book access and use options.
From Committees of RUSA: RUSA Adopts Statement on Equity, Diversity, and Inclusion
Authors: Working Group RUSA
Published: October 2018

The American Library Association’s (ALA) fourth strategic direction—equity, diversity, and inclusion (EDI)—is timely for many reasons given the current political environment in the United States and our country’s difficult history around issues of bias, discrimination, racism, and privilege. These issues have deeply impacted library users and library workers. The pursuit of this strategic initiative provides RUSA members with an opportunity for conversation about how considerations of diversity, equity, and inclusion impact reference and user services in libraries and how we can try to effect positive change. To frame the conversation, RUSA formed a working group to draft an aspirational statement of RUSA values pertaining to EDI in service to library users and RUSA members. The RUSA Board approved this statement at the 2018 Annual Conference in New Orleans, LA. Working group members were Robin Bradford, Alesia McManus, Amber Prentiss, and Chella Vaidyanathan.
Book Review: 36 Workshops to Get Kids Writing: From Aliens to Zebras
Authors: Verbeten Sharon
Published: October 2018

Many children’s librarians know that the five practices of Every Child Ready to Read, one of which is writing, help foster reading and improve literacy skills. The practice of writing also aligns with Common Core Standards at most grade levels. But often, libraries don’t include writing—or at least structured writing—in their program offerings. The author of this book, a youth services librarian, introduces compelling ideas and research evidence for why writing is so important. This introduction leads into the “hows” of presenting writing to children at the library.

This updated edition of Mediavilla’s Creating the Full-Service Homework Center in Your Library shares ideas, policies, budgeting, and assessment suggestions for homework help services for young people. The text is divided into short chapters full of both well-documented research and sensible practical examples of homework centers in action. “Talking Points” scattered throughout offer workable tips on employing the provided suggestions and share examples of successful implementations. The book begins with a discussion of reasons to open a homework center. While some children need serious academic help, some simply need a safe place to spend their after-school time, and others just need some positive interaction with an elder.
Book Review: The Librarian’s Guide to Homelessness: An Empathy-Driven Approach to Solving Problems, Preventing Conflict, and Serving Everyone
Authors: Givens Jessica
Published: October 2018

Public libraries are an invaluable resource for people experiencing homelessness. However, librarians often struggle with how to address the unique needs of those patrons—what do we do when their needs clash with library policies or the comfort of other customers? Ryan Dowd, the executive director of a large homeless shelter in Chicago, draws on his years of experience to provide a set of tools that enable librarians to better serve people experiencing homelessness while improving compliance with library policies. His approach emphasizes empathy, treating all patrons with respect while recognizing the special challenges faced by homeless individuals. Dowd explains how demonstrating empathy enhances our ability to resolve or avoid conflict before resorting to punishment.
Book Review: Promoting Individual and Community Health at the Library
Authors: Rubenstein Ellen
Published: October 2018

Interest in consumer health information has been steadily growing since the mid-twentieth century. As author Mary Grace Flaherty notes in her second chapter, Dr. Benjamin Spock published his book on baby care in 1946, and in 1973, the Boston Women’s Health Collective introduced Our Bodies, Ourselves; both of these supremely popular books offered accessible medical information to the general public and were revised and reprinted many times. In 1996, the Medical Library Association’s Consumer and Patient Health Information Section generated a policy statement addressing how librarians could be involved in facilitating access to consumer health information, and the Institute of Medicine began studying health care delivery in the United States, subsequently affirming that understandable consumer health information is integral to successful medical treatment.
