An Offline Framework for High-dimensional Ensemble Kalman Filters to Reduce the Time-to-solution
Authors: Zheng Yongjun , Albergel Clément , Munier Simon , Bonan Bertrand , Calvet Jean-Christophe
Published: June 2019

Abstract. The high computational resources and the time-consuming IO (Input/Output) are major issues in offline ensemble- based high-dimentional data assimilation systems. Bearing these in mind, this study proposes a sophisticated dynamically running job scheme as well as an innovative parallel IO algorithm to reduce the time-to-solution of an offline framework for high-dimensional ensemble Kalman filters. The dynamically running job scheme runs as many tasks as possible within a single job to reduce the queuing time and minimize the overhead of starting/ending a job. The parallel IO algorithm reads or writes non-overlapping segments of multiple files with an identical structure to reduce the IO times by minimizing the IO competitions and maximizing the overlapping of the MPI (Message Passing Interface) communications with the IO operations. Results based on sensitive experiments shown that the proposed parallel IO algorithm can significantly reduce the IO times and has a very good scalability, too. Based on these two advanced techniques, the offline and online modes of ensemble Kalman filters are built based on PDAF (Parallel Data Assimilation Framework) to comprehensively assess their efficiencies. It can be seen from the comparisons between the offline and online modes that the IO time only accounts for a small fraction of the total time with the proposed parallel IO algorithm. The queuing time might be less than the running time in a low-loaded supercomputer such as in an operational context but the offline mode can be nearly as fast as, if not faster than, the online mode in terms of time-to-solution. However, the queuing time is dominant and several times larger than the running time in a high-loaded supercomputer. Thus, the offline mode is substantially faster than the online mode in terms of time-to-solution, especially for large-scale assimilation problems. From this point of view, it suggests that an offline ensemble Kalman filter with an efficient implementation and a high performance parallel file system should be preferred over its online counterpart for the intermittent data assimilation in many situations.

Published: June 2019

Abstract. Spatial 3-D information on soil hydraulic properties for
areas larger than plot scale is usually derived using indirect methods such
as pedotransfer functions (PTFs) due to the lack of measured information on
them. PTFs describe the relationship between the desired soil hydraulic
parameter and easily available soil properties based on a soil hydraulic
reference dataset. Soil hydraulic properties of a catchment or region can be
calculated by applying PTFs on available soil maps. Our aim was to analyse
the performance of (i) indirect (using PTFs) and (ii) direct
(geostatistical) mapping methods to derive 3-D soil hydraulic properties. The
study was performed on the Balaton catchment area in Hungary, where density
of measured soil hydraulic data fulfils the requirements of geostatistical
methods. Maps of saturated water content (0 cm matric potential), field
capacity (−330 cm matric potential) and wilting point (−15 000 cm matric
potential) for 0–30, 30–60 and 60–90 cm soil depth were prepared. PTFs were
derived using the random forest method on the whole Hungarian soil hydraulic
dataset, which includes soil chemical, physical, taxonomical and hydraulic
properties of some 12 000 samples complemented with information on
topography, climate, parent material, vegetation and land use. As a direct and thus geostatistical method, random forest combined with kriging (RFK) was
applied to 359 soil profiles located in the Balaton catchment area. There
were no significant differences between the direct and indirect methods in
six out of nine maps having root-mean-square-error values between 0.052 and
0.074 cm3 cm−3, which is in accordance with the internationally
accepted performance of hydraulic PTFs. The PTF-based mapping method
performed significantly better than the RFK for the saturated water content
at 30–60 and 60–90 cm soil depth; in the case of wilting point the RFK
outperformed the PTFs at 60–90 cm depth. Differences between the PTF-based
and RFK mapped values are less than 0.025 cm3 cm−3 for 65 %–86  %
of the catchment. In RFK, the uncertainty of input environmental covariate
layers is less influential on the mapped values, which is preferable. In the
PTF-based method the uncertainty of mapping soil hydraulic properties is
less computationally intensive. Detailed comparisons of maps derived from the
PTF-based method and the RFK are presented in this paper.
Mechanism design and parameter optimization of a new asymmetric translational parallel manipulator
Authors: Yang Yi , Tang Yaqi , Chen Haijun , Peng Yan , Pu Huayan
Published: June 2019

Abstract. With the requirement of heavy load for pick-and-place operation, a new 3-DoF asymmetric translational parallel manipulator is invented in this paper. This manipulator is assembled by a kinematic limb with the parallel linear motion elements(PLMEs), and a single loop 2-UPR. Owning to the linear actuators directly connecting the moving and the fixed platforms, this parallel manipulator has high force transmission efficiency, and adapts to pick-and-place operation under heavy load. In this paper, the mobility and singularity are firstly analyzed by screw theory. And the simplified kinematic and dynamic model is established and solved. Secondly, the reaction forces of the prismatic joints in the PLMEs limb are investigated for the mechanism design. Also, the overall performance of the whole manipulator, such as the workspace, condition numbers of Jacobian matrices and motion transmission, etc, are discussed. Thirdly, a compound evaluation function, which involves the factors of workspace volume, transmission efficiency and reaction force, is proposed. In order to obtain a set of better design parameters, the optimization of the 3-DoF translational manipulator is conducted, for the object of maximum of the evaluation function. At last, the prototype is manufactured and experimented to validate the mobility and motion feasibility of this mechanism design.
Machine Learning Analysis of Lifeguard Flag Decisions and Recorded Rescues
Authors: Houser Chris , Lehner Jacob , Wernette Phil
Published: June 2019

Abstract. Rips currents and other surf hazards are an emerging public health issue globally. Lifeguards, warning flags and signs are important and to varying degrees they are effective strategies to minimize risk. In the United States and other jurisdictions around the world, lifeguards use coloured flags (green, yellow and red) to indicate whether the danger posed by the surf and rip hazard is low, moderate, or high respectively. The choice of flag depends on the lifeguard monitoring the changing surf conditions along the beach and over the course of the day using both regional surf forecasts and careful observation. There is a potential that the chosen flag does not accurately reflect the potential risk, which may increase the potential for rescues or drownings. In this study, machine learning used to determine the potential for error in the flags used at Pensacola Beach, and the impact of that error on the number of rescues. A decision tree analysis suggests that the wrong flag was flown on ~ 35 % of days between 2004 and 2008 (n = 396/1125), and that those differences account for only 17 % of all rescue days and ~ 60 % of the total number of rescues. Further analysis reveals that the largest number of rescue days and total number of rescues is associated with days where the flag deployed over-estimated the surf and hazard risk, such as a red or yellow flag flying when the model would suggest a green flag would be more appropriate based on the wind and wave forcing. Regardless whether this is a result of the lifeguards being overly cautious or the rip and surf hazard is associated with weak rips forced by a transverse-bar and rip morphology, the results suggest that beach users are discounting the lifeguard warnings if it isn't consistent with how they perceive the surf hazard. Results suggest that machine learning techniques have the potential to support lifeguard and thereby reduce the number of rescues and drownings.
Rock glacier characteristics serve as an indirect record of multiple alpine glacier advances in Taylor Valley, Antarctica
Authors: Winsor Kelsey , Swanger Kate M. , Babcock Esther , Valletta Rachel D. , Dickson James L.
Published: June 2019

Abstract. The geomorphic record indicates that alpine glaciers in the McMurdo Dry Valleys of southern Victoria Land, Antarctica appear to advance during interglacial periods in response to ice-free conditions in the Ross Sea. Few records of these advances are preserved and/or subaerially exposed, complicating the interpretations of regional glacier response to climate changes. Here, we present geophysical and geochemical analyses of a rock glacier that originates from icefalls fed by alpine Doran Glacier in central Taylor Valley. The rock glacier exhibits a trend of increased weathering of granitic clasts via ventifaction and grussification down-flow. Meltwater ponds on the rock glacier exhibit variable salinity that ranges from freshwater to higher than seawater, with the highest salinity pond near the rock glacier toe. Ground-penetrating radar analyses reveal the feature to possess a primarily clean ice interior, with layers of englacial debris. Stable isotopic data from three ice cores support a glacial origin for the ice within the rock glacier. These data suggest that the current morphology of the rock glacier is the result of multiple events of increased ice contribution caused by advances of Doran Glacier, which is the main source of the ice that cores the rock glacier. We therefore demonstrate the potential of ice-cored rock glaciers to record multiple advances and retreats of Dry Valley glaciers, permitting the interpretation of glacial responses to Pleistocene and Holocene climate change even where direct records are not present.

Abstract. Freshwater discharge from glaciers is increasing across the Artic in response to anthropogenic climate change, which raises questions about the potential downstream effects in the marine environment. Whilst a combination of long-term monitoring programmes and intensive Arctic field campaigns have improved our knowledge of glacier-ocean interactions in recent years, especially with respect to fjord/ocean circulation in the marine environment, there are extensive knowledge gaps concerning how glaciers affect marine biogeochemistry and productivity. Following two cross-cutting disciplinary International Arctic Science Committee (IASC) workshops addressing ‘The importance of glaciers for the marine ecosystem’, here we review the state of the art concerning how freshwater discharge affects the marine environment with a specific focus on marine biogeochemistry and biological productivity. Using a series of Arctic case studies (Nuup Kangerlua/Godthåbsfjord, Kongsfjorden, Bowdoin Fjord, Young Sound, and Sermilik Fjord), the interconnected effects of freshwater discharge on fjord-shelf exchange, nutrient availability, the carbonate system, and the microbial foodweb are investigated. Key findings are that whether the effect of glacier discharge on marine primary production is positive, or negative is highly dependent on a combination of factors. These include glacier type (marine- or land-terminating) and the limiting resource for phytoplankton growth in a specific spatiotemporal region (light, macronutrients or micronutrients). Glacier fjords therefore often exhibit distinct discharge-productivity relationships and multiple case-studies must be considered in order to understand the net effects of glacier discharge on Arctic marine ecosystems.
Investigating spatiotemporal patterns of snowline altitude at the end of melting season in High Mountain Asia, using cloud-free MODIS snow cover product, 2001–2016
Authors: Tang Zhiguang , Wang Xiaoru , Wang Jian , Wang Xin , Wei Junfeng
Published: June 2019

Abstract. The snowline altitude at the end of melting season (SLA-EMS) can be used as an indicator of the equilibrium line altitude (ELA) and therefore for the annual mass balance of glaciers in certain conditions. High Mountain Asia (HMA) hosts the largest glacier and perennial snow cover concentration outside the polar regions, but the spatiotemporal pattern of SLA-EMS under climate change is poorly understood in there. Here, we develop a method for estimating SLA-EMS over large-scale area by using the cloud-removed MODIS fractional snow cover data, and investigate the spatiotemporal characteristics and trends of SLA-EMS during 2001–2016 over the HMA. The possible linkage between the SLA-EMS and temperature and precipitation changes over the HMA is also investigated. The results are as follows: (1) There are good linear regression relationships (R = −0.66) between the extracted grid (30 km) SLA-EMS and glaciers annual mass balance over the HMA. (2) Generally, the SLA-EMS in the HMA decreases with increase of latitude. And due to the mass elevation effect, it decreases from the high altitude region of Himalayas and inner Tibet to surrounding low mountainous area. (3) The SLA-EMS of HMA generally shows a rising trend in the recent years (2001–2016). In total, 75.3 % (24.2 % with a significant increase) and 16.1 % (less than 1 % with a significant decrease) of the study area show increasing and decreasing trends in SLA-EMS, respectively. The SLA-EMS significant increases in Tien Shan, Inner Tibet, south and east Tibet, east Himalaya and Hengduan Shan. (4) Temperature (especially the summer temperature) trends to be the dominant climatic factor affecting the variations of SLA-EMS over the HMA. Under the background of the generally losing glaciers mass in HMA, if the SLA-EMS continues to rise as a result of global warming, it will accelerate the negative mass balances of the glaciers. This study is an important step towards reconstruction the time series of glacier annual mass balance using SLA-EMS datasets at the scale of HMA to better document the relationships between climate and glaciers.

Authors: Oliveira Simone De , Santos Anderson Alves
Published: June 2019

Desde hace años, se buscan métodos y prácticas educativas adecuadas a la realidad cultural y al nivel de especificidades de los jóvenes y adultos. La Educación de Jóvenes y Adultos (EJA) en la Red Municipal de Educación de Belo Horizonte – Minas Gerais, Brasil, prioriza la construcción de una política pedagógica para esta modalidad de enseñanza. El objetivo de esa investigación fue investigar, por medio de observaciones, por la percepción de los profesores, de los alumnos y la coordinación pedagógica, cuales son las principales estrategias pedagógicas desarrolladas para trabajar la diversidad entre los alumnos, característica importante en la EJA. El objeto de estudio fue una escuela de esta red de enseñanza que solamente trabaja con la modalidad EJA. La investigación describió y analizó, a partir da aplicación de encuestas a alumnos y profesores y de la observación directa de clases, las especificidades de los alumnos y el trabajo desarrollado por los profesores. Las metodologías utilizadas fueron el análisis bibliográfico y documental, el método histórico-lógico, el análisis y la síntesis. Una das principales conclusiones fue que existe un deseo manifiesto por parte de los profesores de trabajar las demandas de los alumnos y tener en cuenta sus especificidades, aún es necesario que los profesores continúen su formación para trabajar con la EJA y que la escuela priorice las discusiones, abordando en ellas el trabajo con la diversidad de los alumnos.
Educação inclusiva: como contraponto do atual sistema de ensino homogeneizador e meritocrático
Authors: Farias Juliana Do Nascimento , Da Costa Vanderlei Balbino
Published: June 2019

Este artigo tem por objetivo expor pontos e contrapontos sobre a interpretação da precariedade da educação brasileira atribuída ao novo paradigma da educação inclusiva. Para tanto, apresenta-se discussões sobre a temática com base nos textos “O dualismo perverso da escola pública brasileira: escola do conhecimento para os ricos, escola do acolhimento social para os pobres”, de Libâneo (2012) e “O direito de ser, sendo diferente, na escola”, de Mantoan (2004). Diante dos textos supracitados, este trabalho expõe a seguinte questão norteadora: Será que a educação inclusiva é culpada por promover uma educação assistencialista em detrimento do ensino dos conteúdos sistematizados? A metodologia utilizada foi de pesquisa bibliográfica fundamentada nas postulações de Libâneo (2012), Mantoan (2004) e Zanardini (2014). Os resultados desse estudo demonstraram que a educação inclusiva representa quebra de paradigmas já consubstanciados pelo atual sistema de ensino homogeneizador e meritocrático, assim como, reestruturação da atuação dos profissionais da área. Verificou-se que os pressupostos da educação inclusiva têm sido usurpados pelos slogans neoliberais para camuflar a crise da educação no Brasil, dado que reflete uma ação paliativa de governo com objetivo de cumprir exigências de organismos multilaterais atendendo minimamente uma parcela da sociedade anteriormente excluída, uma vez que ao fragmentar a qualidade da educação a interesses de grupos, a questão deixa de ser uma luta de classe e passa a representar conquistas de alguns grupos outrora excluídos socialmente.

Bipartite network structures and individual differences in sound change
Authors: Dodsworth Robin
Published: June 2019

This paper assesses the influence of social network structure, and the role of the individual, in shaping the loss of the regional vowel system in the Southern U.S. city of Raleigh, North Carolina. The entire front vowel system, including monophthongal /aɪ/ as in ride, is shifting toward the national standard. Previous network studies in sociolinguistics have focused on individual-level network characteristics, such as integration in dense local networks or contact with speakers from different neighborhoods or ethnic groups. By contrast, the Raleigh study focuses on individuals’ positions in the community network structure as represented by a bipartite network of people and the schools they attended. Bipartite networks indicate social proximity between people via their shared participation in an event or organization.With a 189-speaker sample of Raleigh natives, the network measure of structural equivalence offers a view of Raleigh’s community network structure and of the individual’s role in advancing the shift away from the Southern vowel system. Structural equivalence is the extent to which nodes inhabit similar positions within a social network. In this case, it describes the extent to which pairs of speakers attended the same schools. A distance matrix containing each pair’s network proximity is used to predict speakers’ linguistic similarity. The role of the individual and of the social indexicality of Southern variants is considered in the context of aggregate patterns of variation.
Reconsidering asymmetries in voice-mismatched VP-ellipsis
Authors: Poppels Till , Kehler Andrew
Published: June 2019

Previous research on VP-ellipsis has revealed the existence of a Mismatch Asymmetry, whereby cases with passive voice ellipsis clauses and active antecedent clauses are less acceptable than cases with active ellipsis clauses and passive antecedents. According to the memory-based explanation offered by the Recycling Hypothesis (RH; Arregui et al. 2006), this effect arises because passive clauses are more prone to be misremembered as active than the other way around, and hence passive-active mismatches are more likely to create an “illusion of grammaticality”. This paper describes three experiments that explore the source of the asymmetry, with particular attention to the predictions of the RH account on previously unexamined cases. The findings are inconsistent with the predictions of memory-based explanations such as the RH, and instead point to the existence of a penalty against passive ellipsis clauses in subject focus environments, one that applies to both matched and mismatched cases of VP-ellipsis and in both anaphoric and cataphoric discourse configurations. A possible explanation for the penalty is offered as a subject for future work.
The pro-head analysis of the Japanese internally-headed relative clause
Authors: Kitagawa Chisato
Published: June 2019

The objective of this paper is two-fold. One is to advance the view (call it the pro-head analysis) that the so-called internally-headed relative clause (IHRC) in Japanese is a nonrestrictive relative clause whose external head position is occupied by pro functioning as an E-type pronoun. It demonstrates that this view provides a natural framework in terms of which sundry and significant phenomena associated with Japanese IHRCs can be accounted for, including their characteristic properties contrasting with the corresponding change relatives and the doubly-headed relatives. The pro-head analysis contradicts a currently popular claim propagated by a series of papers that rely on null operator movement leading to the thesis that: (i) Japanese IHRCs may exhibit a “change sub-variety” (i.e., “Change IHRC”) that is not reducible to gapless externally light-headed relatives; (ii) Japanese IHRCs are strictly island-sensitive; and (iii) they disallow definite referential semantic heads. The other objective of this paper, therefore, is to present this long overdue challenge by arguing that their claims (i) ~ (iii) are not empirically sustainable, although their claim (iii) presents some difficult issues that defy clear-cut treatment as yet.
Effect of educational guidelines based on health belief model regarding testicular cancer knowledge, practice and beliefs among male nursing students
Authors: El Mezayen Samira E. , Abd El-Hay Seham A.
Published: June 2019

Background: Testicular cancer is considered one of the most important health threats in a young men’s life. However, it is easily detected at an early stage by periodic testicular self-examination (TSE). Awareness of testicular cancer and TSE among university students is very important to aid in early detection and improve health belief. Aim: This study was conducted to evaluate the effect of educational guidelines based on health belief model regarding testicular cancer knowledge, practice and beliefs among male nursing students.Methods: Design: A quasi experimental study design was used and data were collected from Faculty of Nursing, Tanta University. Sample: Proportion stratified random sample of 160 from 500 undergraduate male nursing students were selected as following: about one third of male students from total number of them in different years in the faculty (first, second, third and fourth year). Tools: Three tools were used for data collection. Tool (I): Structure questionnaire sheet to assess students knowledge regarding testicular cancer; Tool (II): Self-reported practices regarding TSE; and Tool (III): Beliefs of students regarding testicular cancer and TSE by Using Health Belief Model (HBM).Results: The results of this study showed that there were significant improvements among students ’knowledge and selfreported practice about testicular cancer & TSE post 3-month and 6-month from educational guidelines, Furthermore, there was improvement in the positive health beliefs about behavioral changes regarding prevention of testicular cancer was observed post 6-month from implementing educational guidelines.Conclusion and Recommendation: These results indicated that educational guidelines about testicular cancer and TSE training are effective in improving knowledge, practice and health belief of young men, but TSE training should be repeated periodically for better efficacy. University faculties should create knowledge and organize workshops about TSE for students and encourage them to perform it regularly.

The objective of this study was to measure the treatment outcome provided by a Brazilian Psychosocial Care Center from the perspective of outpatients and their family members.Methods: A correlational study was performed with 84 outpatients and 40 family members, between 2015 and 2016, interviewing them using the Satisfaction (SATIS-BR), Perception of Change (PCS), Independent Living Skills (ILSS) and Family Burden (FBIS-BR) scales.Results: There was a high index of satisfaction with the mental health service, with a mean of 4.23 for the users interviewed and 4.36 for the family members. The perception of change presented a mean of 2.58 for the patients and 2.19 for the family members. The independent living ability presented a mean of 2.52.Conclusions: The high indices of satisfaction suggest successes, as well as points to be improved in the mental health policy implemented in the municipality. However, reintegration into the labor market was presented as an aspect with a need for investments through health and labor policies, since it was related to the subjective burden.

Introduction: The fund of knowledge on benign prostatic hypertrophy (BPH) has been growing since the 1970s. Citation analysis is a tool by which we can quantify influence of specific articles and assess the growth of a certain topic. This paper seeks to identify trends, as well as draw attention to the most influential papers, authors, and journals. Many analogous studies have been done, but none have been done in the field of BPH.

Methods: We used Thomson Reuters Web of Science to collect articles pertaining to BPH in a two-step fashion. We identified 117 keywords relevant to BPH and using these 117 words, we were able to identify 7302 total articles. These articles were organized by number of citations. Of the top 200 articles, 100 articles were excluded based on title and abstract analysis. One hundred articles were included for final analysis, as this is the standard of citation analysis.

Results: Overall, total citations were slightly correlated with journal impact factor. Author analysis revealed no significant difference between authorship and average citations. Topic analysis showed the most cited topic was surgical management with 657.35 citations per year. Study design analysis showed the predominant study design was the randomized control trial.

Conclusions: By using the two-step methodology, we were able to create a list of the top 100 most influential articles in the field of BPH. In doing so, we illustrated the growth of the field over time and paid tribute to the myriad of papers, authors, and journals that have shaped the field to this day.
The Most Frequent Errors in Academic Writing: A Case of EFL Undergraduate Arab Students in Israel
Authors: Chaleila Wisam , Garra-Alloush Iman
Published: June 2019

The current study examined the most common types of academic writing errors and the causes of such errors made by 44 tertiary EFL Arab-Israeli students. A methodological triangulation was employed in this research. Results and analyses of errors in the written samples revealed that students made a substantial number of errors in both rating scales. In the generic writing performance scale (the qualitative method), 75% of students’ written samples rated poor, and the error frequency rating scale (the quantitative method) showed that the students made 2965 errors, which is a notably large number in proportion to the essay length. The researchers have also inferred that the principal reason for such errors is the triglossic nature of Arabic in Israel. The novelty of this research is that such triglossic nature of Arab-Israelis’ language has not yet been investigated in the field. To this end, the results drawn will be utilised in future research as a platform for exploring effective teaching approaches that may enhance EFL students’ writing performance.

OBJECTIVE: This study focused on the role of extended family in mitigating the stress experienced by parents of children with autism and the possible challenges of involving them, especially in modern Nigerian society. The study identified the sources of stress for parents of children with autism, and considered location and family size factors in stress experienced by parents, the role of the extended family in mitigating the stress and the challenges that may inhibit the involvement of the extended family. 

METHOD: The study adopted a descriptive survey research design and was carried out in South East, Nigeria. All parents and guardians of children with autism in the three special needs schools that cater for children with autism in the two selected states were used for the study. Data was collected using a self-report questionnaire with 36 items to elicit information on the sources of stress for parents and the role of the extended family in mitigating the stress. A semi-structured 26 items interview schedule adapted from Smithfield’s (2011) parents of children with autism questions covering the child's behaviour, parent's feelings, and role of the extended family was also used to generate firsthand information on the issues raised and to complement data collected through the self-report questionnaire. There was a researcher observation guide for monitoring progress in the study. Mean and standard deviation was used to answer the research questions while regression analysis, t-test and Analysis of variance were used to test the null hypotheses at 0.05 level of significance.

RESULTS: The findings revealed that parents of children with autism experience stress that is hinged basically on the behaviour of the children. Family size does not influence parents’ stress experience but location does.  Some parents receive child care and/or financial help sometimes from extended family members.

CONCLUSION: Parents of children with autism face a lot of stress that is hinged basically on the behaviour of the children. Some of the rural parents, however, have the opportunity of getting help sometimes from extended family members since special need schools are not located in their area or even nearby. The extended family relations sometimes offer financial help but from all indications, the modern urbanization has really eroded their help. Family size does not influence parents’ stress experience and role of extended family but location does.

This study aims to ascertain the relationship between inventory management and operational performance of quoted manufacturing firms in the south-east; one of the geographic regions with high industrialization prospects in Nigeria. To achieve this, operational performance of manufacturing firms and their association with components of inventory management; inventory cost, just-in-time approach, materials requirement planning and strategic supplier partnership, was examined through a questionnaire. Three hundred and seventy-one copies of a questionnaire issued to five hundred and thirty-eight sampled respondents of four quoted manufacturing firms in the south-east region of Nigeria were properly filled and found relevant to the study. The study used SPSS and Excel-based descriptive statistics to analyze the data collected. Regression analysis was used to test the hypotheses of the study. Study results conclude that there is a positive significant relationship between; inventory cost, just in time approach, materials requirement planning and strategic supplier partnership and operational performance of quoted manufacturing firms in the south-east region, Nigeria. The study recommends among others that, manufacturing firms in south-east Nigeria should adopt inventory practices such as strategic supplier partnership, just-in-time approach, materials requirement planning and inventory cost control due to the significant effect these practices have on operational performance.

Memory Disorders: Koschaker Rediscovered and Bowdlerized
Authors: Giaro Tomasz
Published: June 2019

The biography of an Austrian specialist in Roman law, Paul Koschaker (1879–1951), who spent the Nazi-time as an elderly professor at important law faculties of Germany, such as Leipzig, Berlin and Tubingen, is reexamined. Recent attempts of image cultivation, which try to acclaim Koschaker the most courageous fighter against every form of totalitarianism in Europe and nearly the patron saint for European jurists, are proved unjustified.
