A new multicopter-based unmanned aerial system for pollen and spores collection in the atmospheric boundary layer
Authors: Crazzolara Claudio , Ebner Martin , Platis Andreas , Miranda Tatiana , Bange Jens , Junginger Annett
Published: March 2019

Abstract. The application of a new particle collection system (PCS) developed in-house
and operated on board a commercially available multicopter unmanned aerial vehicle
(UAV) is presented as a new unmanned aerial system (UAS) approach for in situ
measurement of the concentration of aerosol particles such as pollen grains
and spores in the atmospheric boundary layer (ABL). A newly developed
impactor is used for high-efficiency particle extraction on board the
multicopter UAV. An airflow volume of 0.2 m3 min−1 through the
impactor is provided by a battery-powered blower and measured with an on-board
mass flow sensor. A bell-mouth-shaped air inlet of the PCS is arranged and
oriented on the multicopter UAV to provide substantial isokinetic sampling
conditions by advantageously using the airflow pattern generated by the
propellers of the multicopter UAV. More than 30 aerosol particle collection flights were carried out near
Tübingen in March 2017 at altitudes of up to 300 m above ground
level (a.g.l.), each with a sampled air volume of 2 m3. Pollen
grains and spores of various genera, as well as large (>20 µm)
opaque particles and fine dust particles, were collected, and specific
concentrations of up to 100 particles per m3 were determined by
visual microscopic analysis. The pollen concentration values measured with
the new UAS match well with the pollen concentration data published by the
Stiftung Deutscher Polleninformationsdienst (PID) and by MeteoSwiss. A
major advantage of the new multicopter-based UAS is the possibility of the
identification of collected aerosol particles and the measurement of their
concentration with high temporal and spatial resolutions, which can be used
inter alia to improve the database for modelling the propagation of aerosol
particles in the ABL.

Abstract. The next generation of European polar orbiting weather satellites will carry
a novel instrument, the Ice Cloud Imager (ICI), which uses passive
observations between 183 and 664 GHz to make daily global
observations of cloud ice. Successful use of these observations requires
accurate modelling of cloud ice scattering, and this study uses airborne
observations from two flights of the Facility for Airborne Atmospheric
Measurements (FAAM) BAe 146 research aircraft to validate radiative transfer
simulations of cirrus clouds at frequencies between 325 and 664 GHz
using the Atmospheric Radiative Transfer Simulator (ARTS) and a
state-of-the-art database of cloud ice optical properties. Particular care is
taken to ensure that the inputs to the radiative transfer model are
representative of the true atmospheric state by combining both remote-sensing
and in situ observations of the same clouds to create realistic vertical
profiles of cloud properties that are consistent with both observed particle
size distributions and bulk ice mass. The simulations are compared to
measurements from the International Submillimetre Airborne Radiometer
(ISMAR), which is an airborne demonstrator for ICI. It is shown that whilst
they are generally able to reproduce the observed cloud signals, for a given
ice water path (IWP) there is considerable sensitivity to the cloud
microphysics, including the distribution of ice mass within the cloud and the
ice particle habit. Accurate retrievals from ICI will therefore require
realistic representations of cloud microphysical properties.

Abstract. Lofted mineral dust over data-sparse regions presents considerable challenges to satellite-based remote sensing methods and numerical weather prediction alike. The Southwest Asia domain is replete with such examples, with its diverse array of dust sources, dust mineralogy, and meteorologically-driven lofting mechanisms on multiple spatial and temporal scales. A microcosm of these challenges occurred over 3–4 August 2016 when two dust plumes, one lofted within an inland dry air mass and another embedded within a moist air mass, met over the Southern Arabian Peninsula. Whereas conventional infrared-based techniques readily detected the dry air mass dust plume, they experienced marked difficulties in detecting the moist air mass dust plume, which only became apparent when visible reflectance revealed it crossing over an adjacent dark water background. In combining information from numerical modelling, multi-satellite/multi-sensor observations of lofted dust and moisture profiles, and idealized radiative transfer simulations, we develop a better understanding of the environmental controls of this event, characterizing the sensitivity of infrared-based dust detection to column water vapor, dust vertical extent, and dust optical properties. Differences in assumptions of dust complex refractive index translate to variations in the sign and magnitude of the split-window brightness temperature difference commonly used for detecting mineral dust. A multi-sensor technique for mitigating the radiative masking effects of water vapor via modulation of the split-window dust-detection threshold, predicated on idealized simulations tied to these driving factors, is proposed and demonstrated. The new technique, indexed to independent-sensor description of the surface-to-500 mb atmospheric column moisture, reveals parts of the missing dust plume embedded in the moist air mass, with best performance over land surfaces.
Influence of initial ocean conditions on temperature and precipitation in a coupled climate model's solution
Authors: Tokmakian Robin , Challenor Peter
Published: March 2019

Abstract. This paper describes results of an experiment that perturbed the
initial conditions for the ocean's temperature field of the Community Earth
System Model (CESM) with a well defined design. The resulting 30-member
ensemble of CESM simulations, each of 10 years in length, is used to create
an emulator (a nonlinear regression relating the initial conditions to
various outcomes) from the simulators. Through the use of the emulator to
expand the output distribution space, we estimate the spatial uncertainties
at 10 years for surface air temperature, 25 m ocean temperature,
precipitation, and rain. Outside the tropics, basin averages for the
uncertainty in the ocean temperature field range between 0.48 ∘C
(Indian Ocean) and 0.87 ∘C (North Pacific) (2 standard
deviation). The tropical Pacific uncertainty is the largest due to different
phasings of the ENSO signal. Over land areas, the regional temperature
uncertainty varies from 1.03 ∘C (South America) to 10.82 ∘C
(Europe) (2 standard deviation). Similarly, the regional average
uncertainty in precipitation varies from
0.001 cm day−1 over Antarctica to
0.163 cm day−1 over Australia with a global average of
0.075 cm day−1. In general, both temperature and precipitation
uncertainties are larger over land than over the ocean. A maximum covariance
analysis is used to examine how ocean temperatures affect both surface air
temperatures and precipitation over land. The analysis shows that the
tropical Pacific influences the temperature over North America, but the North
America surface temperature is also moderated by the state of the North
Pacific outside the tropics. It also indicates which regions show a high
degree of variance between the simulations in the ensemble and are,
therefore, less predictable. The calculated uncertainties are also compared
to an estimate of internal variability within CESM. Finally, the importance
of feedback processes on the solution of the simulation over the 10 years of
the experiment is quantified. These estimates of uncertainty do not take into
consideration the anthropogenic effect on warming of the atmosphere and ocean.
Constraining the soil carbon source to cave-air CO2: evidence from the high-time resolution monitoring soil CO2, cave-air CO2 and its δ13C in Xueyudong, Southwest China
Authors: Cao Min , Jiang Yongjun , Lei Jiaqi , He Qiufang , Fan Jiaxin , Zeng Ze
Published: March 2019

Abstract. Cave CO2 plays an important role in carbon cycle in a karst system, which also largely influences the formation of speleothems in caves. The partial pressure of CO2 (pCO2) of the cave air and cave water (cave stream and drip water) in Xueyu Cave was monitored from 2015 to 2016. The pCO2 for cave air and stream over two years showed very similar variations in seasonal patterns, with fluctuated high CO2 concentrations in the wet season and steady low CO2 concentrations in the dry season. Soil CO2 which is largely controlled by soil temperature and soil water content as well as stream degassing are main origins for the Xueyu cave air pCO2. The average values of δ13Csoil, δ13CDIC in June were −23.9 ‰ and −13.4 ‰, respectively; δ13CCO2 of atmospheric air was −10.0 ‰ and δ13CCO2 of cave air was −23.3 ‰. The average values of δ13Csoil, δ13CDIC in November were −18.0 ‰ and −12.2 ‰, respectively; δ13CCO2 of atmospheric air was −9.6 ‰ and δ13CCO2 of cave air was −18.8 ‰. Moreover, the contribution from soil CO2 is higher in June (78.8 %) than in November (67.1 %) based on the model of carbon stable isotopes. The contribution of C from the soil was larger in summer than in winter. The very similar (negative) values of carbon isotopes between soil and cave air CO2 suggests that there were no potential geological/deeper sources with more positive δ13CCO2. Stream pCO2 degases from upper stream to downstream in the cave, resulting in slightly decreased pCO2 but increased carbon isotope values in the downstream. The influence of these regional controls on stalagmite records requires a better understanding of modern interaction between cave CO2 sources, transport paths and mechanisms.
CO2 and CH4 budgets and global warming potential modifications in Sphagnum-dominated peat mesocosms invaded by Molinia caerulea

Abstract. Plant communities play a key role in regulating greenhouse gas (GHG) emissions in peatland ecosystems and therefore in their ability to act as carbon (C) sinks. However, in response to global change, a shift from Sphagnum to vascular plant-dominated peatlands may occur, with a potential alteration in their C-sink function. To investigate how the main GHG fluxes (CO2 and CH4) are affected by a plant community change (shift from dominance of Sphagnum mosses to vascular plants, i.e. Molinia caerulea), a mesocosm experiment was set up. Gross primary production (GPP), ecosystem respiration (ER) and CH4 emission models were used to estimate the annual C balance and global warming potential under both vegetation covers. While the ER and CH4 emission models estimated an output of, respectively, 376 ± 108 and 7 ± 4 gC m−2 y−1 in Sphagnum mesocosms, this reached 1018 ± 362 and 33 ± 8 gC m−2 y−1 in mesocosms with Sphagnum rubellum and Molinia caerulea. Annual modelled GPP was estimated at −414 ± 122 and −1273 ± 482 gC m−2 y−1 in Sphagnum and Sphagnum + Molinia plots, respectively, leading to an annual CO2 and CH4 budget of −30 gC m−2 y−1 in Sphagnum plots and of −223 gC m−2 y−1 in Sphagnum + Molinia ones (i.e., a C-sink). Even if, CH4 emissions accounted for a small part of the gaseous C efflux (ca. 3 %), their global warming potential value makes both plant communities have a climate warming effect. The shift of vegetation from Sphagnum mosses to Molinia caerulea seems beneficial for C sequestration at a gaseous level. However, roots and litters of Molinia caerulea could provide substrates for C emissions that were not taken into account in the short measurement period studied here.

Abstract. Evaporation (E) and transpiration (T) respond differently to ongoing changes in climate, atmospheric composition, and land use. Our ability to partition evapotranspiration (ET) into E and T is limited at the ecosystem scale, which renders the validation of satellite data and land surface models incomplete. Here, we review current progress in partitioning E and T, and provide a prospectus for how to improve theory and observations going forward. Recent advancements in analytical techniques provide additional opportunities for partitioning E and T at the ecosystem scale, but their assumptions have yet to be fully tested. Many approaches to partition E and T rely on the notion that plant canopy conductance and ecosystem water use efficiency (EWUE) exhibit optimal responses to atmospheric vapor pressure deficit (D). We use observations from 240 eddy covariance flux towers to demonstrate that optimal ecosystem response to D is a reasonable assumption, in agreement with recent studies, but the conditions under which this assumption holds require further analysis. Another critical assumption for many ET partitioning approaches is that ET can be approximated as T during ideal transpiring conditions, which has been challenged by observational studies. We demonstrate that T frequently exceeds 95 % of ET from some ecosystems, but other ecosystems do not appear to reach this value, which suggests that this assumption is ecosystem-dependent with implications for partitioning. It is important to further improve approaches for partitioning E and T, yet few multi-method comparisons have been undertaken to date. Advances in our understanding of carbon-water coupling at the stomatal, leaf, and canopy level open new perspectives on how to quantify T via its strong coupling with photosynthesis. Photosynthesis can be constrained at the ecosystem and global scales with emerging data sources including solar-induced fluorescence, carbonyl sulfide flux measurements, thermography, and more. Such comparisons would improve our mechanistic understanding of ecosystem water flux and provide the observations necessary to validate remote sensing algorithms and land surface models to understand the changing global water cycle.
Observations and scaling of tidal mass transport across the lower Ganges–Brahmaputra delta plain: implications for delta management and sustainability
Authors: Hale Richard , Bain Rachel , Goodbred Jr. Steven , Best Jim
Published: March 2019

Abstract. The landscape of southwest Bangladesh, a region constructed primarily by
fluvial processes associated with the Ganges River and Brahmaputra River, is now
maintained almost exclusively by tidal processes as the fluvial system has
migrated east and eliminated the most direct fluvial input. In natural areas such
as the Sundarbans National Forest, year-round inundation during spring high
tides delivers sufficient sediment that enables vertical accretion to keep
pace with relative sea-level rise. However, recent human modification of the
landscape in the form of embankment construction has terminated this pathway
of sediment delivery for much of the region, resulting in a startling
elevation imbalance, with inhabited areas often sitting >1 m
below mean high water. Restoring this landscape, or preventing land loss in
the natural system, requires an understanding of how rates of water and
sediment flux vary across timescales ranging from hours to months. In this
study, we combine time series observations of water level, salinity, and
suspended sediment concentration with ship-based measurements of large
tidal-channel hydrodynamics and sediment transport. To capture the greatest
possible range of variability, cross-channel transects designed to encompass
a 12.4 h tidal cycle were performed in both dry and wet seasons during
spring and neap tides. Regional suspended sediment concentration begins to increase in August,
coincident with a decrease in local salinity, indicating the arrival of the
sediment-laden, freshwater plume of the combined Ganges–Brahmaputra–Meghna
rivers. We observe profound seasonality in sediment transport, despite
comparatively modest seasonal variability in the magnitude of water
discharge. These observations emphasize the importance of seasonal sediment
delivery from the main-stem rivers to this remote tidal region. On tidal
timescales, spring tides transport an order of magnitude more sediment than
neap tides in both the wet and dry seasons. In aggregate, sediment transport
is flood oriented, likely as a result of tidal pumping. Finally, we note that
rates of sediment and water discharge in the tidal channels are of the same
scale as the annually averaged values for the Ganges and Brahmaputra rivers.
These observations provide context for examining the relative importance of
fluvial and tidal processes in what has been defined as a quintessentially
tidally influenced delta in the classification scheme of Galloway (1975).
These data also inform critical questions regarding the timing and magnitude
of sediment delivery to the region, which are especially important in
predicting and preparing for responses of the natural system to ongoing
environmental change.
La memoria de las manos. La realización de un documental de historia de la educación

Este trabajo presenta en retrospectiva el proceso que un equipo interdisciplinar ha seguido a lo largo de cuatro años y cuyo resultado se ve plasmado en septiembre de 2015 con el largometraje documental titulada La Memoria de las Manos. Ecos pedagógicos del legado de C. Freinet en la Región de Murcia. El enfoque que pretendemos mostrar cuenta con dos perspectivas complementarias: la que proporciona la historia de la educación como campo de conocimiento y la que nos muestra el enfoque comunicativo como propuesta para la divulgación de resultados de investigación. La perspectiva que aporta la historia de la educación relata y justifica el proceso de recopilación de fuentes documentales, las dificultades que presenta y la toma de decisiones respecto a ello. Se valoran los condicionantes del tema y se contextualizan adecuadamente las fuentes utilizadas. El enfoque comunicativo, que no por ir en segundo lugar es menos importante, muestra el proceso visto desde la perspectiva de un director de cine, en este caso director del documental. Se ponen de manifiesto las decisiones tomadas y los recursos utilizados en función del público objetivo de la obra. Cabe resaltar que en esta parte del proceso el director tuvo en cuenta en todo momento los criterios de los protagonistas, los maestros, y de los investigadores de historia de la educación que participaron en el mismo. El proceso de producción del film supuso asimismo una forma de hacer innovadora en términos de realización documental ya que se construye como propuesta y resultado de una investigación doctoral: Ficciones constructoras de realidad. El cine de animación documental (Burgos, 2015).
Identidades metamórficas: sobre vestidos simbióticos y bacterias costureras
Authors: Fernández-Nóvoa Helena
Published: March 2019

Este artículo pretende revisar los modos en los que el vestido ha funcionado, en las narrativas tradicionales, como elemento articulador de nuestra identidad como seres humanos en tanto especie. Repasando las concepciones alumbradas desde el contexto de la ciencia sistémica, trataremos de lanzar nuevas miradas a las interacciones convencionales entre cuerpo y vestido, a partir de tres proyectos que establecen un discurso en torno a esta temática desde el ámbito de lo artístico. Estas propuestas modulan nuevos acercamientos al concepto de cuerpo desde una perspectiva particular que hace confluir lo textil con lo bacteriológico. A partir de este marco interdisciplinar, intentaremos articular una reflexión en torno a lo identitario que desarticule miradas antropocéntricas, en esas confluencias entre lo sartorial y lo biológico.

En este trabajo mostramos la influencia que la evolución del software ha supuesto en el desarrollo creativo de nuestra sociedad digital. Dentro del amplio espectro de posibilidades que este fenómeno ha generado, nos centramos en una tendencia creativa de producción audiovisual en directo que revive culturas clásicas, como es el caso de la cultura Rave, a partir de la investigación con la programación de código en vivo para la creación audiovisual mediante el uso software libre, la Algorave. Tomando como referencia a Alex McLean, fundador del mayor evento de Live Coding a escala mundial, la Algorave, realizaremos un recorrido por estas prácticas creativas audiovisuales de Live Coding dentro del ambiente de la Algorave. Mediante la investigación cualitativa a través de diferentes entrevistas, publicaciones y observación del contenido de estas performances, se recogen los contenidos creativos de esta tendencia artística. Desde los años 90, la computadora se ha convertido en una herramienta fundamental en el proceso creativo de los artistas audiovisuales, tanto del directo como de estudio. Se desprende de este estudio que el trabajo con la computadora permite una producción interdisciplinar que deshace las jerarquías entre artista y usuario, además de fomentar la participación transversal entre grupos de investigación.
The Readiness of Village Leaders for Development Challenge: Evidence from Mwanga District Council
Authors: Lawrence Mrutu Lukio
Published: March 2019

There have been several initiatives by the government of Tanzania to facilitating local development since the attainment of independence in 1961. To quicken the process, the idea of enabling local people to be the agents of their own development was advocated through decentralization by devolution, which aimed at empowering grass root communities through their local democratically elected leaders to plan and implement their own development activities. Village leaders who have a mandate of engineering the process of development have been identified as a key catalyst towards development success. With regard to their importance as far as community development is concerned, this paper wanted to find out as to what extent village leaders were prepared in terms of their education level and training programmes to be the source of local development. Using the two cases of Kigonigoini and Kwakoa in Mwanga district, it was found that village leaders were not well prepared and were of low capacity because of their low level of education and the absence of training programmes made them more blunt in engineering local development.

The principle of shared responsibility is the key to harmony and cooperation between recognized employees’ union and management of the university. This study was conducted to analyze the attitude of the members of Wesleyan University Philippines-Faculty and Staff Association (WUPFSA) towards their union. Through the use of descriptive correlational research method, survey questionnaires, interviews, and cross-examination of secondary data, the study was able to: a) describe variables such association-demographic profile of the members, employees’ attitude towards union’s role, as well as problems encountered through the years; and b) determine the significant relationship between the socio-demographic profile of the employees and their attitude towards the association. The study also found out that the positive attitude of the employees towards the union is attributable to the commitment of the officers in the discharge of their duties and responsibilities. The positive attitude of members towards the management not only strengthens the union but also promotes peace and harmony within the educational milieu significantly boosting the morale of employees and generating activities which fosters academic excellence.

Published: March 2019

Post-caesarean surgical site infection (PCSI) is one of the most common cesarean section-related complications. In low- and middle-income countries (LMIC), PCSI prevalence is often under-reported and inaccurate because LMIC surveillance systems are often unable to detect PCSIs developed after discharge; this can ultimately wrongly inform the decision-making related to reducing PCSIs.This paper describes the establishment of a post-discharge PCSI surveillance system for identification of PCSI rate in a district hospital in Rwanda.A total of 540 women underwent CS in the hospital from November 2017 to February 2018, and 536 (99.3%) consented to participate in the surveillance. Among those consented, 22 had no telephone and 174 could not be reached by telephone despite multiple attempts. At the end of this study, a total of 340 women completed the entire surveillance period. The total PCSI rate was 11.5%.Out of all PCSIs, 21% were detected during hospitalization period and 79% were detected during the post-discharge period.The PCSI surveillance system developed in this project covered the 30-day period after surgery and provided a more accurate estimate of PCSI rate.  The system was able to track PCSIs developed after a patient was discharged from the hospital. Long term sustainability of the project must be evaluated.
Risk Factors for Pregnancies Among Females Age 15 to 19 in Rwanda: A Secondary Data Analysis of the 2014/2015 Rwanda Demographic and Health Survey (RDHS)
Authors: Hakizimana Dieudonne , Logan Jenae , Wong Rex
Published: March 2019

Teenage pregnancy is a significant public health problem in developing countries. Due to biological and social factors, teenagers have more negative health outcomes when pregnant. Pregnancy also causes teenagers to drop-out from school, affecting their job opportunities and long-term financial security. As the risk factors for teenage pregnancies are complex and context-specific, effective strategies to reduce teenage pregnancies must be informed by evidence.This study analyzed the data collected by the 2014-2015 Rwanda Demographic and Health Survey in Rwanda. The risk factors associated with 2768 females aged between 15-19 years in the dataset were identified using logistic regression.The overall teenage pregnancy rate was 7.3%. Teens were more likely to have a teenage pregnancy if they were 17 years old (OR=7.04, 95%CI: 2.67 - 18.58, p<0.001), 18 years old (OR=3.78, 95%CI: 1.36 - 10.47, p=0.011), and 19 years old (OR= 3.85, 95%CI: 1.34 - 11.01, p=0.012) compared to teens under 16 years old. Those with secondary or higher education (OR=0.36, 95%CI 0.22 - 0.61, p=<0.001) were less likely to have a teenage pregnancy compared to those with primary school only. Teens had higher odds to have teenage pregnancy if they were married/in union (OR= 45.9, 95%CI: 21.34 - 98.73, P<0.001), and interestingly, if they were using contraceptive methods (OR= 68.9, 95%CI: 29.49 - 160.80, P<0.001).Policy makers should consider programs keeping girls in schools and ensuring that teenagers have access to reproductive health information and reliable contraceptive methods at an early age. Teenage marriage should be discouraged.

NEW TRENDS IN THE MANAGEMENT OF LOGISTICS
IN THE ARMED FORCES OF THE SLOVAK REPUBLIC
Authors: ŠKOLNÍK Miroslav
Published: March 2019

Logistics management is implemented in activities such as planning, organisation, implementation, control and assistance in all functional logistics areas. The Military Doctrine of the Slovak Republic establishes three levels of war - strategic, operational and tactical, which are applied in war and non-military operations. However, in today‘s international environment, it is not possible to determine with certainty at what level the organisational structure operates. All levels are interconnected. The Ministry of Defence and the General Staff of the Slovak Armed Forces focus on the
strategic logistics management. The logistics office resolves operational and some strategic logistics issues. Logistics departments of ground and air forces deal with operational logistics management, influencing the tasks imposed on the commander in the operational plan for the use of Slovak armed forces, including the creation of procedures, doctrines and training documents. At a tactical level, the logistics of departments and units are organically integrated into the structures of their headquarters with their subordinate logistics units. The structure of logistics management in the Armed Forces of the Slovak Republic (AF SR) and the role of its individual elements at the strategic, operational and tactical level is examined in this paper. It concludes by
showing possible ways of logistics management and goals for the future.
MULTI-DOMAIN BATTLE. NEW DOCTRINE
OF THE UNITED STATES ARMED FORCES
Authors: WÓJTOWICZ, PhD Tomasz , KRÓL Dariusz
Published: March 2019

This article describes the newest doctrine of the U.S. Armed Forces, i.e. the Multi- Domain Battle (MDB) concept. It constitutes a description of several operational principles related to a potential conflict with the People’s Republic of China or the Russian Federation, such as the time and space for conducting military operations, the operating environment, the forces (base of operations), the target, the concentration of forces and the operational leeway. The article looks at the origins of the doctrine, the circumstances under which it was formed and people who contributed to its
development. The authors also refer to historical U.S. doctrines, such as the AirLand Battle or AirSea Battle concepts. Along with the authors’ enthusiastic approach to MDB, the article also features some critical opinions which imply that the U.S. Army is not ready for MDB operations. The research methods that were used by the authors included analysis, synthesis, comparison and generalisation. Much space is devoted to analysing the U.S. Army’s official documents, including Multi-Domain Battle: Evolution of Combined Arms for the 21st Century 2025-2040, FM 3-0 Operations and TRADOC Multi-Domain Battle: Combined Arms for the 21st Century. The authors believe that Multi-Domain Battle is about to become the official military doctrine of the U.S. Armed Forces. In spite of the criticism, transformations of individual combat teams in the MDB spirit should be expected in the upcoming years. This doctrine also provides a military response to the geo-political changes occurring in the world, manifested as the United State’s limited role in certain regions, China’s growing power and Russia’s aggressive foreign policy. The conclusions formulated in
the article may serve as the starting point for further studies dealing, inter alia, with the Polish Army’s readiness for conducting military operations, based on the MDB doctrine, jointly with the U.S. Army, the Polish Anti-Access/Area Denial (A2AD) capabilities and the role of military technologies in the MDB doctrine. The article makes use of the exact translation of the term, i.e. “Multi-Domain Battle.” However, the reader should bear in mind that it describes capabilities not only at the tactical level but also in operational terms, enabling the accomplishment of the strategic objective.

Shelf-life Evaluation of Packaged Fermented Cassava Flour
Authors: Lestari Dianika , Liandro Yessica , Ang Elvina , Kresnowati M.T.A. Penia
Published: March 2019

Cassava is a carbohydrate source with high productivity per hectare of plantation. Cassava is made into flour to extend its shelf life. However, traditional flour still has low quality due to its yellowish color and distinct odor. Fermented cassava flour (FERCAF) is produced by fermentation of cassava chips in a circulated retting fermenter by using a combination of Lactobacillus plantarum, Bacillus subtilis, and Aspergillus oryzae, followed by drying and milling. This process has been used successfully to produce flour with a white color and a neutral aroma. To enable industrial scale production and market introduction, the quality deterioration and shelf life of packaged FERCAF should be determined. The objective of this research was to investigate the effect of storage time and packaging type on the physicochemical properties and to determine shelf life of packaged FERCAF. FERCAF was stored in a controlled-incubator over 94 days using two packaging types: LDPE plastic and kraft paper. Based on the result, the number of microorganisms over 94 days of storage was within safe limits. The average estimated shelf life of packaged FERCAF was in the range of 3-4 months at ambient temperature. The shelf life of FERCAF packaged in LDPE plastic was approximately 15 days longer than that packaged in kraft paper.

Pesquisas recentes revelam a necessidade de revisitar essas teses a partir das seguintes antíteses: 1) o aumento da produção nas fronteiras agrícolas ainda é mais influenciado pela tradicional expansão da área cultivada, 2) a expansão para novas fronteiras gera altos custos socioambientais, 3) a aposta na liberalização dos mercados ignora políticas protecionistas de outros países, 4) há grande diversidade de agricultores com pequena produção, mas com potencial de desenvolvimento. Como síntese, o futuro do mundo rural brasileiro passa pela integração vertical do capital nacional ao longo da cadeia produtiva, superando a visão atual restrita à expansão para novas fronteiras agrícolas, com o Estado apoiando estratégias de longo prazo dos segmentos empresarial e familiar.
Difusão horizontal e vertical da política ambiental na Amazônia
Authors: Jacaúna Tiago
Published: March 2019

A Amazônia possui um vasto número de Unidades de Conservação (UC) de diferentes modelos. Todavia, não existe nos estudos sobre política ambiental e criação de UC a incorporação da literatura sobre difusão de políticas públicas. Este artigo objetiva contribuir para suprir esta lacuna, tomando como objeto de análise três modelos distintos de UC. O artigo identifica que os modelos de UC são difundidos por meio de dois principais mecanismos, difusão vertical (top-down e bottom-up) e difusão horizontal. Cada modelo apresenta especificidades e mutações quanto ao processo de difusão da política, dependendo do grau de interdependência dos atores envolvidos no processo decisório, da capacidade de influência social por meio de redes sociais e das pressões políticas externas e internas aos governos nacionais e locais. Este artigo contribui não apenas com incipiente campo de estudos da difusão de política no Brasil, mas enriquece a literatura sobre a política ambiental na Amazônia e as áreas protegidas.
Assistência Técnica e Extensão Rural em comunidades rurais do sul do Amazonas

Published: March 2019

Os serviços de ATER no Brasil auxiliam os produtores rurais na melhoria de seus sistemas produtivos, orientados pela política nacional (PNATER). Este artigo tem por objetivo analisar a execução da PNATER em comunidades rurais localizadas no sul do estado do Amazonas. A metodologia proposta é de cunho qualitativo-quantitativo, tendo como base analítica a análise de conteúdo, e a utilização de dados socioeconômicos dos agricultores tabulados no programa de estatística SPSS. Foram utilizados também dados de campo recolhidos por meio de entrevistas semi-estruturadas e DRP. De posse de um quadro analítico, verificou-se que o serviço de ATER é escasso em grande parte dos estabelecimentos rurais da região analisada. Reconhece-se que a implantação de uma política de ATER voltada à agricultura familiar em modos ambientalmente sustentáveis de produção é limitada, em consequência do baixo investimento no estado do Amazonas em ações de ATER. Concorre ainda a herança difusionista do antigo modelo e do limitado conhecimento dos técnicos sobre a nova política, além da falta de alcance a novas tecnologias sociais por parte dos(as) agricultores(as).

This study aims to identify the aspects that optimize and/or hamper the process of performance appraisal in a public hospital and to discuss strategies that facilitate this process with health professionals. This is a qualitative, exploratory-descriptive study conducted in a public hospital in the southern region of Brazil. Data collection took place through focal group and information was submitted to thematic analysis. The following categories emerged as a result of this study: considerations about the purpose of the evaluation process in the dialogical process of the focal group; the culture of performance appraisal as an optimization / obstacle to the evaluation process; and strategies that facilitate the process of performance appraisal. The results reinforce the need for the institution to conduct performance appraisal based on a reflexive and dialogical process that seeks a critical analysis of the circumstances health professionals work in.

Melilla y la fiebre minera en el primer cuarto del siglo XX
Authors: Madariaga María Rosa de
Published: March 2019

Desde finales del siglo XIX y, sobre todo, principios del XX, Melilla y sus alrededores viven un "síndrome" que no dudamos en calificar de "fiebre minera". Prospecciones, denuncias se suceden sin interrupción en una carrera desenfrenada por obtener concesiones de investigación o de explotación de yacimientos mineros. Pero la situación legal de cada mina seguía estando mal definida hasta la promulgación de un reglamento minero cuya ausencia provocaba rivalidades entre grupos industriales y gobiernos.
La mujer rifeña: un ejercicio de la evolución social beréber
Authors: Douhou El-Hassan
Published: March 2019

La consideración social de la mujer rifeña, desde finales del siglo XIX hasta la actualidad, ha sufrido drásticas evoluciones siempre en relación a los lazos nucleares de la tierra y la jerarquización oligárquica basada en la indiscutible autoridad de los hombres. Pese a todo, históricamente se han manifestado diversas vías de escape para la mujer rifeña, valorada especialmente como nutridora de hombres guerreros para la tribu, y, en muchos casos, como ostentadora del honor/deshonor del propio clan. La irrupción colonial, junto a la presión demográfica y la pobreza de la tierra del Rif, motivaron procesos históricos tales como la emigración de los rífenos a las tierras argelinas y la participación masiva de soldados rífenos en el ejército franquista durante la guerra civil española. Procesos que afectaron profundamente a las bases de la familia y, consecuentemente, al papel detentado en ella por la mujer rifeña.

Published: March 2019

La Universidad de Verano de Agadir, en Marruecos, conlleva una tradición universitaria en torno a la discusión científica de problemas de fondo que afectan a su propia esencia cultural. Durante la Semana Cultural organizada por esta Universidad, en el verano de 1991, se suscitó un tema ciertamente candente: la actualidad y las perspectivas de futuro de la lengua tamazight, mayoritaria en Marruecos y lengua histórica en el marco de los pueblos mediterráneos. En estas páginas se acogen algunas opiniones de científicos especializados en la lengua y cultura tamazight, nucleadas en torno a un debate, en lengua francesa, coordinado por Rachid A. Raha, quien junto a El Hamouti Asmaa, lo ha recogido y traducido especialmente para Aldaba.
