THE SOCIETY OF MINANGKABAU IN TULIS St. SATI’S SENGSARA MEMBAWA NIKMAT: BETWEEN LOCAL TRADITIONS AND ISLAMIC TEACHINGS
Authors: Mauli Betty
Published: September 2016

The culture of Minangkabau is different from the ones generally existing in Indonesia, particularly compared to the Javanese culture. Therefore, the culture of Minangkabau is often considered as a contradictory or antithesis of the Javanese culture, frequently represented as the overall culture of Indonesia. The peculiarity of Minangkabau culture lays in its matrilineality which influences lineage and inheritance. The contradictory matter refers to the society of Minangkabau that is the largest Islamic followers in Indonesia, yet their ancestral traditions are not completely in line with the Islamic teachings, some even are contradictory. It is a common knowledge that a literary work is not born from an ‘empty culture’ meaning that a literary work must be influenced by its author. Even some of literary experts believe that a society described in a novel is the real society where the author lives. It is similar to the novel of Sengsara Membawa Nikmat of Sutan Sati, which is the object of this paper. The novel describes the society of Minangkabau in the early 20th century, at the end of 1920s to be exact.This research shows how the efforts of Minangkabau people in adopting the Islamic teachings completely and how Islam adapts to the Minangkabau hereditary traditions. Some of the traditions may exist in accordance with the Islamic teachings, but some do not. Even there is a need to gather all headman of the ethnic group to decide a case which is not in line with Islam, whether following pure traditions or Islam as it should be. 
THE CHRONICLE OF TERRORISM AND ISLAMIC MILITANCY IN INDONESIA
Authors: Zakiyah Zakiyah
Published: September 2016

This paper examines the chronicle of terrorism in Indonesia and the relationship between terrorism and Islamic militancy in this nation. This research focused on bombing cases from 2001 to 2012 Data was gathered through documentary research including primary and secondary resources. This research shows that after the fall of the Suharto regime in 1998, there were bomb attacks on various targets and militant extremists were able to return to Indonesia after long period of exile abroad. They started again their activities including disseminating their radical ideology, building networks and recruiting new members in Indonesia, as well as preparing for militant actions. The perpetrators of these terror attacks were mostly associated with the Islamic radical groups like Jemaah Islamiah and Majlis Mujahidin Indonesia. These two militant groups had a close relationship with Darul Islam, an organization founded during the colonial era that aimed to establish an Islamic state and to apply Syariah as a state law. In addition, both groups became a political window for al-Qaeda in Indonesia. 
MEDITAÇÕES EM TORNO DA RELAÇÃO ENTRE ENGENHARIA HIDRÁULICA E GEOMORFOLOGIA FLUVIAL: BREVE APANHADO HISTÓRICO E APONTAMENTOS PARA NOVAS PESQUISAS
Authors: Vervloet Roberto José Hezer Moreira
Published: September 2016

Este artigo trata de uma linha importante de reflexão epistemológica existente na história da geomorfologia fluvial: a da sua relação com a engenharia hidráulica e a hidrodinâmica. Ao estudarmos este ramo da geomorfologia percebemos como sua gênese histórica teve origem e foi dependente das discussões científicas e epistemológicas que houve no nascedouro da engenharia hidráulica e da hidrodinâmica fluvial. Desta forma, evidenciamos a tese de que o estágio de discussão estabelecido por engenheiros hidráulicos a partir da passagem do século XVII para o XVIII foi fundamental para o avanço dos conhecimentos e fundação das bases epistemológicas para a constituição das teorias fluviais sobre o relevo terrestre no início do século XIX (nascedouro da geomorfologia fluvial). Abre-se, desta forma, excelente campo para novas pesquisas e reflexões sobre a filosofia histórica desta disciplina.
CARACTERIZAÇÃO MORFOSSEDIMENTAR DOS EFEITOS DO EVENTO DE FLUXO DE SEDIMENTOS DE 2009 NA VILA DE SÃO VICENTE, CACHOEIRO DE ITAPEMIRIM - ES

Published: September 2016

Durante o verão de 2009 a região Sul do Espírito Santo foi assolada por fluxos de sedimentos ao longo de suas vertentes mais íngremes. A vila de São Vicente, distrito de Cachoeiro de Itapemirim, se destacou neste contexto, tendo sido palco de deslizamentos de encostas e sistemática remobilização de depósitos pré-existentes, cujo efeito foi o soterramento parcial do distrito por um corpo sedimentar de proporções quilométricas. O presente trabalho define tecnicamente os limites espaciais da corrida e também classifica a entidade morfossedimentar gerada. Para tanto, lança-se mão de técnicas cartográficas e estratigráficas, as quais são integradas e confrontadas ao contexto geológico regional bem como a modelos análogos presentes na literatura especializada. Com a realização do estudo pretende-se fornecer as bases para o estabelecimento de critérios adequados de uso e ocupação na região, bem como para estudos mais aprofundados do fenômeno, envolvendo técnicas de alcance tridimensional como as geofísicas.
GÊNESE E MORFODINÂMICA DAS BARREIRAS ARENOSAS NO FLANCO NORTE DO DELTA DO RIO PARAÍBA DO SUL (RJ)

Published: September 2016

A formação de barreiras arenosas é comum em deltas dominados por ondas, associada ao expressivo aporte sedimentar dos rios. Nesses ambientes é possível o desenvolvimento de barreiras do tipo spit, ilha-barreira e sistema barreira-laguna. Historicamente essas feições foram associadas ao desenvolvimento assimétrico dos deltas e ao papel da deriva litorânea. Nesse sentido, o objetivo do presente trabalho é investigar a gênese e a morfodinâmica das barreiras arenosas que ocorrem no flanco norte do delta do rio Paraíba do Sul, considerando aspectos relacionadas às porções submarina e emersa do delta. Foram calculados dados de ondas e sentido de transporte litorâneo; coletados perfis batimétricos junto à costa, perfis topográficos na barreira emersa e mapeamento em planta a partir de sensoriamento remoto sobre imagens de alta resolução espacial. Foi possível identificar, em escala de detalhe, estágios de desenvolvimento e evolução associados à formação de barras submarinas na frente deltaica; a emersão de barreira arenosa na forma de spit; a progradação lateral a partir das correntes de deriva litorânea; e a conexão do spit ao continente, passando a isolar um sistema lagunar. Este processo foi considerado como um dos mecanismos de gênese de cristas de praia que formam a planície deltaica ao norte do rio Paraíba do Sul. Recentemente, tais feições e processos têm sido interpretados como decorrente de um padrão de ondas assimétricas que chegam à linha de costa com ângulo de obliquidade elevado, produzindo as feições de instabilidade e a assimetria do delta.

A classificação supervisionada por assinaturas geomorfométricas é um procedimento que pode auxiliar no mapeamento de formas de terreno a partir da utilização de medidas de similaridade ou distância. Este trabalho tem como objetivo comparar os métodos supervisionados de classificação a partir de medidas de similaridade e distância para o mapeamento do relevo. A comparação foi realizada no Campo de Instrução Militar de Formosa (GO), seguindo os seguintes passos: aquisição de dados HydroSHEDS, geração de imagens de curvatura, seleção de assinaturas geomorfométricas; classificação formas de terreno usando o método de classificação por ângulo espectral (SAM) e a distância euclidiana (DE); comparação da classificação através da matriz de tabulação cruzada, análise de modelo de elevação em 3D, avaliação da média e do desvio padrão das curvaturas para cada classe mapeada e observação em campo. A seleção de assinaturas geomorfométrica considerou as seguintes etapas: (a) redução dos atributos geomorfométricos pela transformação de Fração Mínima de Ruído (MNF); (b) redução espacial pelo Índice de Pureza de Pixel (PPI); e (c) a seleção manual pelo n-Dimensional Visualizador. O processo de classificação adotou 14 AGs que descrevem dois comportamentos: Tipo 1 quando a curvatura longitudinal tem um valor maior que a curvatura transversal; e Tipo 2 quando ocorre o inverso. O processo foi simplificado para seis classes de formas de terreno (FT): Convexo/Convexo (Cx/Cx); Côncavo/Convexo (Cc/Cx); Côncavo/Côncavo (Cc/Cc); Côncavo/Retilíneo (Cc/Rt); Convexo/Retilíneo (Cx/Rt); Retilíneo/Retilíneo (Rt/Rt). No mapeamento SAM, as formas de relevo predominantes são Cc/Rt, Cx/Rt e Cc/Cx, indicando uma heterogeneidade com muitas áreas de transição e côncavas. A classificação a partir da DE mostrou prevalência de feições retilíneas (Rt/Rt). Apesar disso, essa FT apresentou os menores desvios e valores médios próximos de zero para todas as curvaturas, indicando que a DE foi o método mais eficiente para o mapeamento das áreas retilíneas.
DETERMINAÇÃO DA EROSÃO COSTEIRA NO ESTADO DE PERNAMBUCO ATRAVÉS DE GEOINDICADORES

Published: September 2016

Processos erosivos podem ser identificadas por meio de geoindicadores. O presente estudo classificou geoindicadores decorrentes da erosão no litoral de Pernambuco, no nordeste brasileiro. A metodologia foi baseada na detecção em campo da presença ou ausência de dez indicadores de erosão previamente descritos na literatura como recorrentes no litoral brasileiro. Estes indicadores foram agrupados em 4 classes de intensidade, sendo: nula (sem geoindicadores), baixa (geoindicadores ecológicos que não alteram significativamente a paisagem), moderada (geoindicadores morfológicos que alteram significativamente a paisagem) e alta (geoindicadores causados pela ação antrópica). Os principais geoindicadores observados foram: pós-praia estreito ou inexistente, escarpa erosiva nas dunas, obras estruturais de proteção costeira, e árvores na face de praia ou com raízes expostas. Ao longo dos 172 km de praias arenosas do estado de Pernambuco foi identificado que 48% não apresentaram nenhum geoindicador de erosão, 8% apresentaram geoindicadores de baixa intensidade, 16% de moderada intensidade e os demais 28% apresentaram geoindicadores de alta intensidade de erosão. Esses resultados foram comparados com a variação da linha de costa entre os anos de 2005 e 2014, obtida por meio de análise de imagens de satélite e em trabalho de campo, respectivamente. Uma análise estatística entre a presença de geoindicadores de erosão e as taxas de variação da linha de costa, mostra que não há boa correlação entre as duas variáveis. Por isso concluiu-se que os geoindicadores observados podem ser decorrentes de eventos erosivos anteriores ao período analisado, ou em virtude de alterações antrópicas no sistema, como o avanço da urbanização em direção ao mar e não necessariamente a um processo erosivo.
A PERENE E IRRENUNCIÁVEL TAREFA DE UMA TEOLOGIA LIBERTADORA
Authors: Rivas Eugenio , Tavares Sinivaldo Silva
Published: September 2016

“A teologia da libertação segue viva – e isto é muito importante –, e estou praticamente seguro disto, como um movimento irreversível e que não vai ser desterrado jamais da Igreja latino-americana. Assim se expressava Juan Luis Segundo há mais de quarenta anos, nos primórdios da Teologia da Libertação (TdL). O que chama a atenção neste pronunciamento quase visceral, uma espécie de grito no Gólgota, é o fato de, desde seus inícios, a TdL se defrontar com crônicas que anunciavam sua morte ou a davam, de fato, como morta. Para esses cronistas, se trataria de uma teologia non nata, no sentido literal do termo. Parece que, nesse caso, decretar sua morte equivaleria a não reconhecer sua existência de fato e de direito. Em outras palavras, para não se deixar confrontar pela interpelação posta pela TdL, prefere-se decretar sua morte. Tal expediente acaba, paradoxalmente falando, confirmando a pertinência e a relevância da TdL.
Robot Hands and Sensing
Authors: Kaneko Makoto ,   Computer Science and Engineering, Kyushu Institute of Technology
Published: September 2016

It is not an overstatement that the history of robot hands is equal to that of 40-year-old manipulators. Initial hands were based on the simple ON/OFF switching system, with pneumatic or hydraulic power used as a source. The hands could realize their primary purpose of firmly grasping an object, however, it was impossible to achieve the dexterous manipulating motion which was another important function. Since the latter half of 1970's, the dexterous functions have been in demand for robot hands such as the functions of an inspection robot for the power plant. This caused research institutes in many countries to start development projects on multi-fingered hands. The Okada-Hand, Salisbury-Hand, and Utah/MIT-Hand are particularly well-known among multi-fingered hands developed through such projects. In parallel with this research and development, theoretical research activities progressed for stable grasping, fingertip force analysis, and grasping force control. Theoretical studies of hands reached a peak in both quality and quantity in the latter of 1980's. However, the experimental studies using actual multifingered hands were far behind the theoretical studies. Based on the reconsideration of the importance of experimental validation, experimental works have been done to verify the theory of stable grasping or manipulation with actual hands. From another perspective, researches have recently been started in an attempt to use fingers not only as actuator for grasping, but also as an active sensor for recognizing the external world with tactile motion. This causes the research field of hand to spread. Based on the current status of hands researches, this special issue will compile conventional works and provide an outlook for future hands. The editor of this issue will be very pleased if this material can provide with any useful information to hand researchers. Finally, the editor wishes to express his sincere thanks to the contributors.

Published: September 2016

The reconstruction of ancient diets by means of stable isotopes analyses acquires a deeper meaning when their results are compared with other odonto-skeletal indicators which are strongly contextualized in the light of historical and archaeological evidence. Nevertheless, the outcomes can be contradictory or, more realistically, they may not completely satisfy our hypotheses on how complex and diverse conditions - such as health status, life style, diet and nutrition - can actually interrelate in the life course of an individual.

In this study we present and discuss evidences from Isola Sacra and Velia, two Roman Imperial Age coastal towns. The õ15N and õ13C values are compared with demographic and health status parameters, such as age, sex, stature, auricular exostoses, DISH, cribra orbitalia, enamel defects.

Bridging the Gap from Classroom-based Learning to Experiential Professional Learning: A Hong Kong Case
Authors: Du-Babcock Bertha
Published: September 2016

This paper describes and evaluates a funded longitudinal teaching development project that aims to bridge the gap from classroom-based theory learning to experiential professional learning, and thereby prepare ideal and competent world class graduates. To align with the University's shared mission to foster links with the business community, the design of the internship program has a threefold purpose and was implemented in stages. It intends to enhance students' professional awareness-knowledge-skills through a multi-leveled approach integrating classroom learning with professional practice. A debriefing mechanism was also built in enabling students to share their learning and professional challenges, and theory application to problem-solving scenarios. A 360 degree multiple evaluation procedure were used to measure the project effectiveness, including the use of industry consultants, student interns, hosts, and academic supervisors.   The project has proved to promote closer ties with the business community and enhance students' professional competencies to increase future success in the competitive job market. The impact of the internship program is significant in two aspects.  From the perspective of student learning, the internship allows students to understand how they can improve business efficiency by applying communications theories.  From the teaching perspective, the successful and unsuccessful intern experiences can be drawn upon in developing class-room teaching. These lessons can focus on preparing students to solve real-world business communication problems.

This research aims at investigating the effect of YouTube videos and pictures as the authentic materials on EFL Indonesian students’ writing performance. The experimental research is conducted by using quasi-experimental design. This research employs two groups experimental. This is comparing two groups to see which one is effective to be used in helping the students in writing. The first group is employed by using YouTube videos and the second group is treated by using pictures. Both of YouTube and pictures are the authentic materials which help the students to have better writing performance. The subjects are the second semester students of English Department, IKIP PGRI Madiun. Both of the groups, the students are asked to write paragraph by using YouTube videos and pictures as the authentic materials. The data are analyzed by using Independent t-test. The result of the study shows that there is significantly different between the students who write paragraph after being treated by using YouTube videos and by using pictures as the authentic materials. The students who are treated by using YouTube videos have lower writing performance than the students who are treated by using pictures. The mean of the students who write paragraph after being treated by using YouTube videos as authentic materials is lower than those who are treated by using pictures. This means that using pictures in writing are better than using YouTube videos to help the students in writing performance.

Published: September 2016

Rev.esc.adm.negEsta investigación pretende establecer la influencia del precio y las estrategias de comunicación visual, basadas en simbología cultural sobre la preferencia de marcas ecológicas en la categoría de productos de aseo en la ciudad de Bogotá, buscando fomentar el consumo sostenible en los hogares. Para ello, se realizaron dos fases: un estudio de tipo descriptivo para establecer la estrategia de precio más persuasiva para el consumidor en un producto ecológico en la categoría de aseo. Posteriormente en la fase dos, se realizó un estudio experimental mediante un diseño factorial 2x2x2, donde la primera variable independiente fue comunicación visual, la segunda, el enmarcamiento ecológico y la tercera, el precio; variable que actuó como elemento de influencia utilizada en cada grupo experimental. Los participantes fueron expuestos a estímulos visuales de tipo bidimensional y tridimensional, relacionados con las estrategias de precio; los resultados muestran, que de la manera como se comunica el precio, se present una alta incidencia en la preferencia de compra, debido a que los consumidores son más perceptibles a los descuentos y a las ofertas. Otro de los hallazgos relevantes fue la estrategia de posicionamiento en marcas verdes, las cuales deben generar en los consumidores una garantía que realmente es un producto que aporta al cuidado medioambiental y para ello, se requiere de información precisa y detallada en el diseño, los empaques, los envases, la marca y demás atributos del producto; pues en definitiva, en términos publicitarios que la comunicación visual en consumo sustentable cumple una función también informativa.

Published: September 2016

Rev.esc.adm.negEn la búsqueda de mejores resultados que apalanquen la sostenibilidad empresarial, se han desarrollado diversas metodologías enfocadas a la eficiencia y la productividad. Siguiendo esta línea, las corrientes de Gestión del Talento Humano buscan trabajadores altamente productivos y tener bajas tasas de rotación de personal (Bruce, 2006; Wu & Lee, 2001; Fisher, 2000; Lyons, 2006). Sin embargo, la mayoría de estas aproximaciones no trascienden la versión reduccionista del mercado que ve a las empresas sólo como productoras de bienes/ servicios (Schumacher, 1975), ni los paradigmas gerenciales que generan estructuras contrarias a la gestión del recurso humano (Maslow, 1968; Berger y Luckmann, 1967; Senge et.al., 1994). La Gerencia Humanista es la excepción, ofrece otra perspectiva gerencial desde la concepción de las personas en la empresa, no como recursos sino como lo que son, seres humanos. Sus principios se centran en la alteridad, las no-ideologías y las obligaciones sociales organizacionales (Largacha-Martínez, 2010b). En este artículo, se presentan los resultados de la investigación cualitativa de siete empresas, coordinada por la Red de Gerencia Humanista (Von Kimakowitz, et. al, 2011) y se analizan con relación a la excelencia y aprendizaje organizacional.

Novel Insights Into Mechanisms of Oil Recovery by Use of Low-Salinity-Water Injection
Authors: Sohrabi M.. , Mahzari P.. , Farzaneh S. A. , Mills J. R. , Tsolis P.. , Ireland S..
Published: September 2016

The underlying mechanism of oil recovery by low-salinity-water injection (LSWI) is still unknown. It would, therefore, be difficult to predict the performance of reservoirs under LSWI. A number of mechanisms have been proposed in the literature, but these are controversial and have largely ignored crucial fluid/fluid interactions. Our direct-flow-visualization investigations (Emadi and Sohrabi 2013) have revealed that a physical phenomenon takes place when certain crude oils are contacted by low-salinity water, leading to a spontaneous formation of micelles that can be seen in the form of microdispersions in the oil phase.

In this paper, we present the results of a comprehensive study that includes experiments at different scales designed to systematically investigate the role of the observed crude-oil/brine interaction and micelle formation in the process of oil recovery by LSWI. The experiments include direct-flow (micromodel) visualization, crude-oil characterization, coreflooding, and spontaneous-imbibition experiments. We establish a clear link between the formation of these micelles, the natural surface-active components of crude oil, and the improvement in oil recovery because of LSWI. We present the results of a series of spontaneous- and forced-imbibition experiments carefully designed with reservoir cores to investigate the role of the microdispersions in wettability alteration and oil recovery. To further assess the significance of this mechanism, in a separate exercise, we eliminate the effect of clay by performing an LSWI experiment in a clay-free core. Absence of clay minerals is expected to significantly reduce the influence of the previously proposed mechanisms for oil recovery by LSWI. Nevertheless, we observe significant additional oil recovery compared with high-salinity-water injection (HSWI) in the clay-free porous medium. The additional oil recovery is attributed to the formation of micelles stemming from the crude-oil/brine-interaction mechanism described in this work and our previous related publications. Compositional analyses of the oil produced during this coreflood experiment indicate that the natural surface-active compounds of the crude oil had been desorbed from the rock surfaces during the LSWI period of the experiment when the additional oil was produced.

The results of this study present new insights into the fundamental mechanisms involved in oil recovery by LSWI and new criteria for evaluating the potential of LSWI for application in oil reservoirs. The fluid/fluid interactions revealed in this research can be applied to oil recovery from both sandstone and carbonate oil reservoirs because they are mainly derived from fluid/fluid interactions that control wettability alteration in both sandstone and carbonate rocks.
Learning Is Change: Creating an Environment for Sustainable Organizational Change in Continuing and Higher Education
Authors: Schultz Christie
Published: September 2016

This article explores the ways in which learning itself is a form of organizational change and, as such, supports organizational readiness for change. The study considers a continuing education unit within a major Canadian university that managed to transform its decentralized and independent student records and administration system (student registration, student financials, student academic records) by merging into the university’s central student management system.The technological implementation and transformation took place over 18 months and was enabled by a series of formal committees and working groups, involving a wide range of members across the university’s communities and within the continuing education unit. The empirical data consist of responses given during in-depth interviews with a set of participants involved in the change initiative and technology implementation. Managers’ reactions to and reflections on organizational change figure prominently in the research findings and discussion.The article aims to show that creating an environment for sustainable organizational change in higher education, and perhaps more generally, is supported by recognizing that learning itself is change, and that workplace learning may therefore help to create organizational readiness for change.
What’s on the Minds of CAUCE Members? CAUCE Institutional Members’ Survey 2012
Authors: Carter Lorraine , Nowrouzi Behdin
Published: September 2016

This paper presents findings based on CAUCE’s 2012 institutional members’ survey. Findings are considered in relation to an earlier iteration of the same survey in 2009. Three important areas for the reader’s consideration emerged. The first is increasing interest by CAUCE members in distance education and technology-supported models and practices. A second key message ties to the value that CAUCE members place on networking with their colleagues. Finally, continuing education units across Canada continue to be valued for their revenue-generating capacity during fiscally challenging times although, at other times, there can be ambivalence towards continuing education.
Corn Hybrid Response to In‐Furrow Starter Fertilizer as Affected by Planting Date

Use of in‐furrow starter fertilizer (IFSF) is common in the Upper Midwest to enhance early‐season corn (Zea mays L.) growth because of cold soils in the early spring which limit P uptake by corn. The objective of this study was to evaluate the agronomic and economic responses of corn to IFSF and how this was affected by planting date (PD) for hybrids of contrasting relative maturity (RM). A 3‐yr experiment was conducted in 2010 to 2012 at two locations in southern Minnesota which evaluated IFSF at 0 and 65 kg ha−1 of 100–150–0 (g kg−1 N–P–K) with three corn hybrids (94‐, 99‐, and 104‐d RM) planted on three dates spaced on 10‐ to 16‐d intervals. Delaying PD resulted in greater corn plant density, grain moisture at harvest, and kernel m−2, and decreased early‐season plant height, days to silking, kernel mass, and corn grain yield. Planting a later‐RM hybrid resulted in greater early‐season plant height, days to silking, grain moisture at harvest, kernel mass, and biomass and grain yield. In‐furrow starter fertilizer increased early‐season plant height and kernel mass and decreased days to silking, grain moisture at harvest, and kernel m−2. Economic net return to grain production was not affected by IFSF. Results from this study confirm that planting mid‐ to late‐RM hybrids during late April to mid‐May produces greatest net return in the Upper Midwest, and that the response of grain yield to IFSF is not affected by PD for hybrids of differing RM.

Core Ideas

A P‐based starter fertilizer applied in‐furrow increased early corn growth and decreased grain moisture at harvest, but did not increase grain yield on soils testing medium to high in P.

Corn hybrids later in relative maturity and earlier planting increased economic net return.

Net return per hectare was not increased when in‐furrow starter fertilizer was utilized on medium to high P‐testing soils.

A small reduction in grain moisture at harvest can reduce grain drying expenses to offset the cost of in‐furrow starter fertilizer.

The likelihood of a profitable economic net return to in‐furrow starter fertilizer is not affected by corn planting date or hybrid relative maturity.
Robust Increases of Land Equivalent Ratio with Temporal Niche Differentiation: A Meta‐Quantile Regression

Intercropping has been shown to be land use efficient, but there is a large variation in the land equivalent ratio (LER) among studies. We used quantile regression to estimate the effect of temporal niche differentiation and its interaction with other key characteristics of intercropping, i.e., crop type combination, N fertilizer, relative density, and intercropping pattern, using data from the intercropping literature. Quantile regression characterizes the entire distribution of the response metric by estimating quantiles of this distribution. This method gives a comprehensive characterization of the diversity of the response in the population. In this study, the effect of temporal niche differentiation on the LER was positive and significant across all quantiles (10, 15, …, 85, 90%). The response of the LER to temporal niche differentiation was similar in C3–C3 and C3–C4 intercrops except at low quantiles (below 20%), where a stronger response was found in C3–C4 than in C3–C3 intercrops. There was a negative effect of N fertilizer on the LER in the absence of temporal niche differentiation at all tested quantiles. At low LER (quantiles <20%), this negative effect was alleviated by increasing temporal niche differentiation due to a positive interaction between N fertilizer and temporal niche differentiation. The results indicate that temporal niche differentiation has a robust positive effect on the LER across a wide range of LERs, but the strength of this effect is influenced by intercrop characteristics, especially at low to median LER values. Case‐specific experiments are therefore indispensable for identifying advantageous species mixtures and optimal management adapted to local conditions.

Core Ideas

Land equivalent ratio (LER) of intercrops increases with temporal niche differentiation (TND).

The positive effect of TND on LER is robust across a wide range of LER.

At lower LER, the effect of TND is stronger in C3–C4 than C3–C3 intercrops.

N fertilizer amount interacted negatively with TND but only at lower LER.

Quantile regression complemented insights obtained with ordinary regression.

Land application of biosolids to low‐fertility soil can improve soil quality by increasing concentrations of macronutrients and trace elements. Mixing biosolids with sawdust could reduce the risks of contaminant accumulation posed by rebuilding soils using biosolids alone. We aimed to determine the effects of biosolids and biosolids‐sawdust on the plant quality and chemical composition of sorghum, rapeseed, and ryegrass. Plants were grown in a greenhouse over a 5‐mo period in a low‐fertility soil amended with biosolids (1250 kg N ha−1), biosolids‐sawdust (0.5:1), or urea (200 kg N ha−1). Biosolids application increased the biomass of sorghum, rapeseed, and ryegrass up to 14.0, 11.9, and 4.1 t ha−1 eq, respectively. Mixing sawdust with biosolids resulted in a growth response similar to biosolids treatments in rapeseed but nullified the effect of biosolids in sorghum. Urea fertilization provided insufficient nutrients to promote rapeseed growth and seed production, whereas seed yields after biosolids application were 2.5 t ha−1. Biosolids and biosolids‐sawdust application enhanced plant quality by increasing element concentrations, especially Zn, and potentially toxic elements (Cd, Cr, Ni) did not exceed food safety standards. An application of 50 t ha−1 of biosolids, equivalent to 1250 kg N ha−1, did not exceed current soil limits of Cu, Zn, and Cd and hence was effective in rebuilding soil without accumulating contaminants. The effect of mixing sawdust with biosolids varies with plant species but can further enhance plant nutrient quality in biomass and seeds, especially P, Cu, Zn, Mn, Fe, S, and Na.

Core Ideas

Biosolids application showed potential for Zn enrichment in all plant species.

Biosolids and sawdust applied to soil enables growth of rapeseed in low‐fertility soil.

Toxic elements like Cd were not increased to levels dangerous for human health.

Biosolids and sawdust increased seed quality and hence potentially plant products.

Increasing production of biowastes, particularly biosolids (sewage sludge), requires sustainable management strategies for their disposal. Biosolids can contain high concentrations of nutrients; hence, land application can have positive effects on plant growth and soil fertility, especially when applied to degraded soils. However, high rates of biosolids application may result in excessive nitrogen (N) leaching, which can be mitigated by blending biosolids with other biowastes, such as sawdust. We aimed to determine the effects of biosolids and sawdust on growth and N uptake by sorghum, rapeseed, and ryegrass as well as N losses via leaching. Plants were grown in a greenhouse over a 5‐mo period in a low‐fertility soil amended with biosolids (1250 kg N ha−1), biosolids‐sawdust (0.5:1), or urea (200 kg N ha−1). Urea application increased biomass production of sorghum and ryegrass but proved insufficient for rapeseed on low‐fertility soil. Biosolids application increased plant N concentrations in ryegrass and rapeseed and increased N uptake into the seeds of sorghum, increasing seed quality. Biosolids application did result in lower N leaching compared with urea, irrespective of plant species, and N leaching was unaffected by mixing the biosolids with sawdust. There was an indication of biological nitrification inhibition in the rhizosphere of sorghum. Rapeseed had similar growth and N uptake into biomass in biosolids and biosolids‐sawdust treatments and hence was the most promising species with regard to recycling fresh sawdust in combination with high rates of biosolids on low‐fertility soil.

Core Ideas

Mixing sawdust with biosolids did not reduce NO3− leaching irrespective of plant species.

Compared with urea, biosolids application did not result in higher N loss via leaching.

Results indicated biological nitrification inhibition of sorghum.
