Published: September 2016

Linear quadratic regulator is a powerful technique for dealing with the control design of any linear and nonlinear system after linearization of the system around an operating point. For small systems, which have fewer state variables, the transformation of the performance index from scalar to matrix form can be straightforward. On the other hand, as the system becomes large with many state variables and controllers, appropriate design and notations should be defined to make it easy to automatically implement the technique for any large system without the need to redesign from scratch every time one requires a new system. The main aim of this article was to deal with this issue. This article shows how to automatically obtain the matrix form of the performance index matrices from the scalar version of the performance index. Control of a full-vehicle in cornering was taken as a case study in this article.
Surgical Preparation for Articular Cartilage Regeneration in the Osteoarthritic Knee Joint
Authors: Mika Joerg , Clanton Thomas O. , Ambrose Catherine G. , Kinne Raimund W.
Published: September 2016

Purpose:

Autologous chondrocyte implantation (ACI) is a treatment option even in early osteoarthritis (OA). Surgical preparation for ACI should avoid penetration of the subchondral bone plate to prevent hemorrhage, fibrin clot formation, and subsequent activation of the inflammatory response.

Hypothesis:

Current surgical procedures with ring curettes preserve the integrity of the subchondral bone plate, even in patients with OA.

Methods:

Subchondral femoral bone plates ( n = 40) of OA knees undergoing total knee arthroplasty were prepared in vivo using standard, non–brute-force debridement for ACI. To approach regular wear/early OA, only cartilage with maximally grade 3A International Cartilage Repair Society score was prepared. Effects were analyzed by light microscopy.

Results:

In 87.5% of the specimens (35/40), standard debridement did not violate the tide mark, except for occasional minor openings with a smooth edge (diameter approximately 20 µm). In contrast, 5/40 samples (12.5%) showed one large area with a missing bone plate and an open bone marrow space. Twenty-eight specimens (70%) showed at least remnants of uncalcified cartilage.

Conclusion:

On the basis of size/fine structure, the occasional minor openings are likely due to increased vascular penetration through the tide mark in the pathologically altered bone-cartilage interface in OA. The consequences of limited hemorrhage through minor openings or selected large defects following in vivo debridement are still unknown. Thus, standard debridement appears suitable for cartilage regeneration even in OA defects.

Background

The Japanese severity criteria for acute pancreatitis (AP), which consist of a prognostic factor score and contrast‐enhanced computed tomography grade, have been widely used in Japan.

Objective

This large multicenter retrospective study was conducted to validate the predictive value of the prognostic factor score for mortality and complications in severe AP patients in comparison to the Acute Physiology and Chronic Health Evaluation II (APACHE II) score.

Methods

Data of 1159 patients diagnosed with severe AP according to the Japanese severity criteria for AP were retrospectively collected in 44 institutions.

Results

The area under the curve (AUC) for the receiver‐operating characteristic curve of the prognostic factor score for predicting mortality was 0.78 (95% confidence interval (CI), 0.74–0.82), whereas the AUC for the APACHE II score was 0.80 (95% CI, 0.76–0.83), respectively. There were no significant differences in the AUC for predicting mortality between two scoring systems. The AUCs of the prognostic factor scores for predicting the need for mechanical ventilation, the development of pancreatic infection, and severe AP according to the revised Atlanta classification were 0.84 (95% CI, 0.81–0.86), 0.73 (95% CI, 0.69–0.77), and 0.83 (95% CI, 0.81–0.86), respectively, which were significantly greater than the AUCs for the APACHE II score; 0.81 (95% CI, 0.78–0.83) for the need for mechanical ventilation (p  = 0.03), 0.68 (95% CI, 0.63–0.72) for the development of pancreatic infection (p  = 0.02), and 0.80 (95% CI, 0.77–0.82) for severe AP according to the revised Atlanta classification (p  = 0.01).

Conclusion

The prognostic factor score has an equivalent ability for predicting mortality compared with the APACHE II score. Regarding the ability for predicting the development of severe complications during the clinical course of AP, the prognostic factor score may be superior to the APACHE II score.

Authors: Jelley Clare R , Kurukulaarachchi Kurukula ASH , Forster Luke , Bardgett Harry , Singh Rajindra , Addla Sanjai K
Published: September 2016

Objective:

To compare robotic partial nephrectomy (RAPN) with open partial nephrectomy (OPN) to assess efficacy and impact of learning curve.

Methods:

From 2010 to 2015 159 patients had a partial nephrectomy (82 OPN and 77 RAPN). All data were collected prospectively. We compared the demographics, peri and postoperative outcomes.

Results:

Mean age was 60 years in both groups; 59% of patients were men. Tumour size was larger in the open group (34 mm vs 30 mm; P<0.08), but RENAL nephrometry scores greater than 6 were comparable (over 60%). Mean ischaemic time was longer in the RAPN group (18 vs 13 minutes; P<0.04) but complication rates were similar. The RAPN cohort had a reduced estimated blood loss (100 ml vs 300 ml; P<0.01) and shorter median hospital stay (2 vs 5 days; P<0.01). Only two patients in each group were margin positive. The RAPN cohort demonstrated reduced estimated blood loss and a trend towards more complex tumours with increasing learning curve.

Conclusion:

RAPN is superior to OPN in terms of reduced hospital stay and estimated blood loss without compromising oncological outcomes. This service can be delivered safely and effectively in a low to medium volume cancer centre; these results are similar to published figures from high volume international centres.

Published: September 2016

The objective of this study was to assess the effectiveness of an 8-week mindfulness-based cognitive therapy (MBCT) group intervention to reduce psychological distress as well as to strengthen self-esteem, resilience, and general well-being for individuals living with a chronic illness and/or other health challenges. This pilot study employed a pre–posttest design to evaluate the outcome of the intervention for individuals receiving care in a Community and Family Medicine department and a Women’s Health Centre located in an urban downtown hospital. A total of 42 patients were enrolled in the study and 35 participants completed the intervention. Thirty-five of 42 enrolled participants completed the intervention. Twenty-eight participants completed the pretest and posttest assessments, which demonstrated statistically significant improvement on most outcome measures, including the Center for Epidemiological Studies–Depression Rating Scale (CES-D), Depression Anxiety Stress Scale (DASS), Affect Balance Scale (ABS), the Resilience Scale (RS), and the Five-Item World Health Organization Well-Being Index (WHO-5). Large effect sizes were observed for the CES-D, the ABS, and the DASS Stress subscale. Observed improvements were sustained at 4 weeks posttreatment. Results are consistent with studies indicating that MBCT offers promise in alleviating psychological distress for those who are seeking care in primary health care settings. Continued focus on how to best implement MBCT in primary health care, particularly for those with comorbid physical and mental health conditions, supports the World Health Organization’s recommendation to integrate evidence-based mental health care within primary health care to promote equitable access to care for those most in need.
Predicting Freshman Grade Point Average From College Admissions Test Scores and State High School Test Scores
Authors: Koretz Daniel , Yu Carol , Mbekeani Preeya P. , Langi Meredith , Dhaliwal Tasmin , Braslow David
Published: September 2016

The current focus on assessing “college and career readiness” raises an empirical question: How do high school tests compare with college admissions tests in predicting performance in college? We explored this using data from the City University of New York and public colleges in Kentucky. These two systems differ in the choice of college admissions test, the stakes for students on the high school test, and demographics. We predicted freshman grade point average (FGPA) from high school GPA and both college admissions and high school tests in mathematics and English. In both systems, the choice of tests had only trivial effects on the aggregate prediction of FGPA. Adding either test to an equation that included the other had only trivial effects on prediction. Although the findings suggest that the choice of test might advantage or disadvantage different students, it had no substantial effect on the over- and underprediction of FGPA for students classified by race-ethnicity or poverty.
A picture is worth a thousand data points: an imagery dataset of paired shrub-open microsites within the Carrizo Plain National Monument
Authors: Noble Taylor J , Lortie Christopher J , Westphal Michael , Butterfield H. Scott
Published: September 2016

Background

Carrizo Plain National Monument (San Joaquin Desert, California, USA) is home to many threatened and endangered species including the blunt-nosed leopard lizard (Gambelia sila). Vegetation is dominated by annual grasses, and shrubs such as Mormon tea (Ephedra californica), which is of relevance to our target species, the federally listed blunt-nosed leopard lizard, and likely also provides key ecosystem services. We used relatively nonintrusive camera traps, or trail cameras, to capture interactions between animals and these shrubs using a paired shrub-open deployment. Cameras were placed within the shrub understory and in open microhabitats at ground level to estimate animal activity and determine species presence.

Findings

Twenty cameras were deployed from April 1st, 2015 to July 5th, 2015 at paired shrub-open microsites at three locations. Over 425,000 pictures were taken during this time, of which 0.4 % detected mammals, birds, insects, and reptiles including the blunt-nosed leopard lizard. Trigger rate was very high on the medium sensitivity camera setting in this desert ecosystem, and rates did not differ between microsites.

Conclusions

Camera traps are an effective, less invasive survey method for collecting data on the presence or absence of desert animals in shrub and open microhabitats. A more extensive array of cameras within an arid region would thus be an effective tool to estimate the presence of desert animals and potentially detect habitat use patterns.

Authors: Yang Jongcheol , Choe Goeun , Yang Sumi , Jo Hyerim , Lee Jae Young
Published: September 2016

Background

Hydrogels that possess hydrophilic and soft characteristics have been widely used in various biomedical applications, such as tissue engineering scaffolds and drug delivery. Conventional hydrogels are not electrically conductive and thus their electrical communication with biological systems is limited.

Method

To create electrically conductive hydrogels, we fabricated composite hydrogels of hyaluronic acid and polypyrrole. In particular, we synthesized and used pyrrole-hyaluronic acid-conjugates and further chemically polymerized polypyrrole with the conjugates for the production of conductive hydrogels that can display suitable mechanical and structural properties.

Results

Various characterization methods, using a rheometer, a scanning electron microscope, and an electrochemical analyzer, revealed that the PPy/HA hydrogels were soft and conductive with ~ 3 kPa Young’s modulus and ~ 7.3 mS/cm conductivity. Our preliminary in vitro culture studies showed that fibroblasts were well attached and grew on the conductive hydrogels.

Conclusion

These new conductive hydrogels will be greatly beneficial in fields of biomaterials in which electrical properties are important such as tissue engineering scaffolds and prosthetic devices.
Abdominal obesity and cardiometabolic risk in children and adolescents, are we aware of their relevance?
Authors: Forkert Elsie C. O. , Rendo-Urteaga Tara , Nascimento-Ferreira Marcus Vinicius , de Moraes Augusto Cesar Ferreira , Moreno Luis A. , de Carvalho Heráclito Barbosa
Published: September 2016

Obesity prevalence has increased worldwide over the last decades and has reached alarming rates in low middle-income countries. Childhood has been affected by this epidemic, leading to premature dramatic health problems.

Adipose tissue is currently considered as an endocrine organ modulating an inflammatory state and important metabolic processes (insulin resistance, hypertension, glucose intolerance) leading to consequences of the cardiovascular system. This situation may be worst if the excess of body fat distribution such as abdominal obesity (AO) is involved because it is associated with a more atherogenic risk profile determining the cardiometabolic risks mainly in children and adolescents.

Hence, the knowledge regarding the association between AO and cardiometabolic factors aims to prevent and treat the obesity in this young population, avoiding early harmful consequences of adulthood health.

Published: September 2016

Background

The benefits of caloric restriction (CR) on the protection against age-related neurodegenerative diseases have been the subject of several studies. However, the effects of CR on the central nervous system are still poorly understood since most studies were carried out in mature animals. The present study aimed to investigate whether the age at onset of CR could differently affect the redox status of the rat hippocampus.

Methods

Thirty-two male Wistar rats at 35 days old (35d; n = 16) and 65 days old (65d; n = 16) were fed ad libitum or subjected to 30 % CR (n = 8 group/age) for 12 weeks. At the end of the experiment, the rats were euthanized, blood was collected, and the hippocampus was dissected for measuring the redox status.

Results

CR in 35d and 65d rats induced a 16 and 21 % reduction in body weight gain, respectively, compared to controls (p < 0.05). Urea, total cholesterol, triacylglycerol, HDL cholesterol, and LDL cholesterol concentrations were lower in CR 35d rats than in 35d controls (p < 0.05). No differences were detected between the CR groups and controls in the object recognition test (p > 0.05) and in superoxide dismutase activity, nitric oxide content, and lipid peroxidation levels (p > 0.05). However, glutathione peroxidase activity was higher (p < 0.0001) in 65d rats compared to that in 35d rats, and GSH content was higher (p < 0.05) in CR-fed rats compared to that in controls at both ages.

Conclusions

In conclusion, CR increased GSH content when started at both ages but did not affect the activity of antioxidant enzymes and the level of ROS in the hippocampus. In addition, CR did not induce any detrimental effects on memory and nutritional status when started in both 35d and 65d rats.
Elastic wavefield tomography with physical model constraints
Authors: Duan Yuting , Sava Paul
Published: September 2016

Data-domain elastic wavefield tomography is an effective method for updating multiparameter elastic models that exploits much of the information provided by observed multicomponent data. However, poor illumination of the subsurface by P- and S-waves often prevents reliable updates of the model parameters. Moreover, differences in illumination, amplitude, and wavelength between P- and S-waves can distort the intrinsic physical relationships between the reconstructed model parameters. We have developed a method for elastic isotropic wavefield tomography that explicitly constrains the relationship between P- and S-wave velocities. By incorporating a model constraint term in the objective function, we confine P- and S-velocity updates to a physical area defined by prior information, for example, by laboratory measurements or well logs. We have determined that this physical constraint yields models that are more physically plausible, compared with models obtained using only the data misfit objective function.
Single-well moment tensor inversion of tensile microseismic events
Authors: Grechka Vladimir , Li Zhao , Howell Bo , Vavryčuk Václav
Published: September 2016

Microseismic data acquired in a single observation well parallel to the axis of rotational symmetry of surrounding rocks — typically, in a vertical well drilled through a horizontally layered isotropic or vertically transversely isotropic formation — cannot be uniquely inverted for six independent components comprising the full seismic moment tensor. To constrain the inversion for such a survey geometry and medium symmetry, one might assume certain physical properties of seismic sources, the properties relating otherwise independent moment components to each other, regularizing moment tensor inversion, and helping reduce its ambiguity. Our paper examines one possibility of this kind: the assumption of a tensile fracture, rupturing the focal region along a plane of its greatest weakness. Mathematical formulation of inversion of single-well microseismic records for the parameters of tensile fractures reveals that the true solution, always recoverable from properly acquired data, might be accompanied by two spurious solutions. The analysis of those solutions leads to a criterion that, although not perfect, makes it possible to select the correct solution for the majority of elastic models. After being tested on synthetic, our methodology is applied to a field data set recorded with multiple vertical downhole arrays, demonstrating that the results of dual-well moment tensor inversion can be replicated with single-well data.

Option Pricing for a Jump-Diffusion Model with General Discrete Jump-Size Distributions
Authors: Fu Michael C. , Li Bingqing , Li Guozhen , Wu Rongwen
Published: September 2016

We obtain a closed-form solution for pricing European options under a general jump-diffusion model that can incorporate arbitrary discrete jump-size distributions, including nonparametric distributions such as an empirical distribution. The flexibility in the jump-size distribution allows the model to better capture leptokurtic features found in real-world data. The model uses a discrete-time framework and leads to a pricing formula that is provably convergent to the continuous-time price as the discretization is increased. The solution is easy to implement with fast convergence properties. Numerical results illustrate the efficiency and accuracy of the proposed model and highlight its robustness and flexibility.

Authors: Pinsornsak P. , Naratrikun K. , Kanitnate S. , Sangkomkamhang T.
Published: September 2016

Objectives

The purpose of this study was to compare the joint space width between one-leg and both-legs standing radiographs in order to diagnose a primary osteoarthritis of the knee.

Methods

Digital radiographs of 100 medial osteoarthritic knees in 50 patients were performed. The patients had undergone one-leg standing anteroposterior (AP) views by standing on the affected leg while a both-legs standing AP view was undertaken while standing on both legs. The severity of the osteoarthritis was evaluated using the joint space width and Kellgren-Lawrence (KL) radiographic classification. The t-test was used for statistical analysis.

Results

The mean medial joint space width found in the one-leg and in the both-legs standing view were measured at 1.8 mm and 2.4 mm, respectively (p < 0.001, 95% CI 0.5 to 0.7). 33%, 47.4% and 23.1% of the knees diagnosed with a KL grade of I, II and III in the both-legs standing views were changed to KL grade II, III and IV in the one-leg standing views, respectively. No changes for KL IV osteoarthritis diagnoses have been found between both- and one-leg standing views.

Conclusions

One-leg standing radiographs better represent joint space width than both-legs standing radiographs. 32% of both-legs standing radiographs have changed the KL grading to a more severe grade than that in the one-leg standing radiographs.

Is this the new age of consent?
Authors: Umar Gezala
Published: September 2016

Consent is a fundamental prerequisite before any examination and/or treatment can be undertaken. It is executed by clinicians every day of their working life and has become second nature to them, with very little changes in practice through the years. Recent cases in law have now formalised a practice to which many clinicians already adhere. This article will concentrate on the consent of adults with capacity and touch on those lacking temporary capacity but will not discuss the consent of children. It will also include a brief outline of historical cases to the present day.
Is impairment in cognitive inhibition in the acute phase of major depression irreversible? Results from a 10‐year follow‐up study
Authors: Årdal Guro , Hammar Åsa
Published: September 2016

Objectives. Even though many studies demonstrate cognitive impairment in the acute phase of depression and several studies indicate that this impairment might be long lasting despite symptom reduction and recovery, there is a lack of longitudinal studies on this field with considerable follow‐up length. The aim of this study was to investigate whether the impairment observed in cognitive inhibition in the acute phase of depression is reversible or irreversible in a 10‐year follow‐up assessment.

Design. A longitudinal study of 38 individuals, 19 with recurrent unipolar depression and 19 healthy controls matched for gender, age, and education were included in the study.

Method. Cognitive inhibition was investigated using the Stroop test at three different occasions: acute phase, short‐term (6 months), and long‐term (10 years) follow‐up.

Results. The results show that recurrent major depressive disorder patients have a long‐lasting impairment in inhibition as measured by the Stroop test in 10‐year follow‐up. Further there is high consistency in inner group performance suggesting that severe impairment in the acute phase of illness is associated with severe impairment 10 years later despite recovery in the patient group.

Conclusions. The results show that impairment in cognitive inhibition is long lasting when present in the acute phase of recurrent depression. Impaired cognitive inhibition might be an irreversible vulnerability marker for recurrent depression.
Nucleolar Reorganization Upon Site-Specific Double-Strand Break Induction
Authors: Franek Michal , Kovaříková Alena , Bártová Eva , Kozubek Stanislav
Published: September 2016

DNA damage response (DDR) in ribosomal genes and mechanisms of DNA repair in embryonic stem cells (ESCs) are less explored nuclear events. DDR in ESCs should be unique due to their high proliferation rate, expression of pluripotency factors, and specific chromatin signature. Given short population doubling time and fast progress through G1 phase, ESCs require a sustained production of rRNA, which leads to the formation of large and prominent nucleoli. Although transcription of rRNA in the nucleolus is relatively well understood, little is known about DDR in this nuclear compartment. Here, we directed formation of double-strand breaks in rRNA genes with I- PpoI endonuclease, and we studied nucleolar morphology, DDR, and chromatin modifications. We observed a pronounced formation of I- PpoI-induced nucleolar caps, positive on BRCA1, NBS1, MDC1, γH2AX, and UBF1 proteins. We showed interaction of nucleolar protein TCOF1 with HDAC1 and TCOF1 with CARM1 after DNA injury. Moreover, H3R17me2a modification mediated by CARM1 was found in I- PpoI-induced nucleolar caps. Finally, we report that heterochromatin protein 1 is not involved in DNA repair of nucleolar caps.

Authors: Setiawan Arief Ameir Rahman , Sulaswatty Anny , Haryono Agus
Published: September 2016

Innovation is one of the most critical issues in research institutions which can be performed through certain routes within the technology transfer mechanism. As the demands of research implementation are increasing, a better mechanism should be deployed to foster innovation. This study will investigate the possibilities for technology transfer mechanism improvements by (i) identifying a number of steps required for innovation; (ii) measuring the efficiency of each step; and (iii) exploring the most efficient routes to innovate through the Dijkstra algorithm. Cases of research on essential oils and derivatives in the Research Center for Chemistry (RCC) of the Indonesian Institute of Sciences (LIPI) will be examined as the working example for the study. As a result of this study, a model containing a recommended sequence for the most efficient steps to innovation can be proposed. Using the proposed model, the efficiency rate of the technology transfer mechanism was increased twice, suggesting the possibility of stimulating innovation performance.

Published: September 2016

Areca palm is an ornamental palm largely used in landscape which propagate occur by seeds germination. However, the biometry and the endogenous and exogenous factors than can limit propagation of this plant are poorly known, so this work was aimed characterize biometrics of fruits and seeds of areca palm and evaluate the germination of seeds in different substrates. For this, the biometric analyses of length, diameter and weight were recorded; the description of internal and external morphology of frit and seed were also studded. The treatments to improvement of seed germination were intact seeds (T1), intact seeds soaked in 500 mg L-1 GA3 solution (T2), physically scarified seeds with the aid of sandpaper (T3) and physically scarified seeds after immersion in 500 mg L-1 GA3 solution (T4). The Seeds were sown in containers containing sand, coir dust or vermiculite. The areca pal fruits and seeds are both, elliptical shape and the weight of fruits and seeds is 1.70g and 1.04g, respectively. There is positive correlation between fruit weight and length and diameter of the fruit and just like the diameter has a positive correlation with the diameter of the seed. The mechanical scarification improve the seed germination. The Coir dust is the most atrophied substrate to seed germination of areca palm. The seed germination of Areca palm is hypogeal and the protrusion of the haustorium was observed at 59 days after sowing and the plantlets is fully grown at 153 after sowing.

Wer macht eigentlich unsere Siedlungslandschaft? Diese Frage wird von Städtebauer_innen sowie Planer_innen meist beantwortet, indem sie sich selbst ins Zentrum stellen. Jedoch zeigen nicht nur umstrittene Großprojekte wie die Hamburger Elbphilharmonie oder der Berliner Flughafen, dass hierbei auch die Bauverwaltung eine in ihrer Wirkmacht oft unterschätzte Rolle spielt - sie ist es, die im Modus des Erteilens von Baugenehmigungen aktiv in das Leben und in die gebaute Umwelt eingreift.

Mathematical model has many benefits in life, especially the development of science and application to other fields. The mathematical model seeks to represent real-life problems formulated mathematically to get the right solution. This research is the application of mathematical models in the field of biology that examines the interaction of the two populations that host populations and parasitoid populations. This study differs from previous studies that examine the interaction of two more species that prey and predators where predators kill prey quickly. In this study the parasitoid population slowly killing the host population by living aboard and take food from the host population it occupies. In this study of differential equations are used to construct a mathematical model was particularly focused on the stability of the local mathematical model of interaction of two differential equations that host and parasitoid populations. Stability discussed in this study are stable equilibrium points are obtained from the characteristic equation systems of differential equations host and parasitoid interactions. Type the stability of the equilibrium point is determined on the eigenvalues of the Jacobian matrix. Analysis of stability is obtained by determining the eigenvalues of the Jacobian matrix around equilibrium points.

Purpose: Due to the competitiveness required in this port sector, analyzes the efficiency of the operations become relevant. Therefore, the main goal of this paper is to assess the technical efficiency of the operations in Brazilian public container terminals, considering the current and the projected demand (based on the nominal capacity) up to 2052.Design/methodology/approach: An efficiency ranking was established applying the Grey Relational Analysis method to all the Brazilian public containers. After that, the efficiency levels were forecasted for the year 2052, considering the historical data of terminals’ activity, the amount of used resources and their nominal capacities.Findings: The findings shows that the most efficiency terminals did not reach above 80% efficiency, even considering that they are the ones that best allocate their assets based on their demand. Furthermore, the improvement of technical efficiency of terminals does not depend only on the spare capacity; it must be a combination of resources, based on the increase in demand.Research limitations/implications: In this study, the limitations are related to the selection of a linear demand growth that implies in a high margin of error to be considered until 2052, compared to what will be accomplished. Besides, the container terminals were considered isolated from others on the same port but the equipment might be shared by different terminals.Practical implications: the paper might help port managers in the planning of container terminals’ for the next years, calling attention for the need of find balance between capacity and efficiency use of resources.Originality/value: the originality is related to the fact that we analyzed the composition of equipment (besides of the spare capacity) and the forecast of the technical efficiency helping in the planning of this sector. Besides, the application considered the Brazilian container terminals’.

Published: September 2016

This paper presents an action-research project aiming at improving the performance of “just-in-time, just-in-sequence” auto parts manufacturing and delivery in three tier-1 suppliers of the Nissan plant in Barcelona. This research was conducted at the Barcelona School of Engineering (ETSEIB) and promoted by the Nissan factory in Barcelona. In this paper, first, the concept of synchronous manufacturing is explored. After  several improvement ideas are spotted within the Nissan plant, the paper focuses on the suppliers. An intervention approach is proposed.  Suppliers are categorized and selected suppliers are analyzed (by means of three case studies, each one corresponding to a different type of  supplier).  This research contributes to understanding how synchronous manufacturing and delivery can be extended to suppliers and the existing drawbacks. The critical variables in synchronous manufacturing and delivery and the relations between them are identified in a conceptual model termed the M-S Model. Implications for suppliers are derived, allowing us to improve the performance of the whole synchronous manufacturing system. A piece of software is developed to help companies schedule  a smooth flow of components, making synchronous manufacturing easier.  Results may help decision makers develop a supply management system, including policies, procedures and the necessary resource deployment.

Published: September 2016

The market provides a means of survival for the local and urban communities. The local farmers, local artisans, and other informal sectors find the market as their source of income and food and a place of relaxation. They find the market as a place where they meet friends. The article seeks to understand and analyze how informal sectors cluster groups agglomerate in and around the Mendi Local Market (LM) area of Papua New Guinea. This research has made particular reference to Street Vendors (SV) who are operating their daily activities in and along the market corridor and exert their influences to the LM and the public. The study provides the scenario to understand the impact of the social relations of the informal street vendors and their daily associated influences on LM. This article seeks to trace and to understand how informal market clusters are operating and concentrating around the local market. The conclusion suggests that the relationships of the informal sector, street vendors, and local market should be promoted through an appropriate inclusive policy and regulatory environment.The market provides a means of survival for the local and urban communities.

SOCIAL CAPITAL MOBILIZATION STRATEGY TO SUSTAIN COMMUNITY ENTREPRENEURSHIP IN URBAN NEIGHBORHOOD
Authors: Nugroho Prihadi
Published: September 2016

Entrepreneurs in cities are prone to direct market change and urban growth in a country. Those who do not possess strong business network and strategic alliance are likely out of the game immediately. Building community entrepreneurship thus becomes critical to provide collective business network and learning, particularly for smaller entrepreneurs and new entrants, through the mobilization of social capital. This paper aims to examine how urban community institutionalizes the embedded stock of social capital in the neighborhood to cultivate sound entrepreneurial ambience parallel with the individual pursuit of profit maximization. The multiple strategies of incorporating traditional and informal inherited values into the contemporary dynamics of market and urban growth are quite successful to sustain the continuation of home-based industry in the neighborhood. The case study approach was undertaken to observe the re-emergence of local batik industry in Kampung Laweyan of Surakarta Municipality, Indonesia. The result demonstrates that social cohesion safeguarding is the key to encourage collective entrepreneurial skills development in the community albeit it does not affect much the building of stronger inter-firm cooperation.

Pidie is one of the districts in Aceh Province that has been suffering from flooding. Frequent disasters, especially flooding associated with various causative factors, need mitigation efforts. An appropriate land use planning by considering the risk aspects especially in flood is an important step. Objectives of this study are to determine the factors influencing the flood hazard, to map the areal distribution vulnerable to flood, to analyze the relations of land use in the flood hazard area, and to analyze the relations between the planned spatial pattern and the flood hazard area. ,Multicriteria analysis was used to determine the factors influencing the flood hazard. Spatial analysis was used in mapping the class of flood hazard, the relations of land use in the flood hazard area, and the relations between the planned spatial pattern and the flood hazard area. The results show that the main factors influencing flood vulnerability are land use/cover (0.408), rainfall (0.266), and slope (0.184). Based on the classification of flood vulnerability, the area can be divided into more vulnerable (37.75 %), less vulnerable (30 %), and mildly vulnerable (22.76 %). The vulnerability classes of the land use/cover are: less vulnerable (99.99 %) and more vulnerable (97.57 %) dominated by forest cover; mildly vulnerable (51.07%) and vulnerable (92.65%) dominated by mixed farming; and very vulnerable (97%) dominated by settlement. The flood vulnerability of the planned spatial pattern can be classified as follows: 95.44 % of the conservation area is dominated by less vulnerable and more vulnerable, while 71.20 % of the cultivation area can be categorized into mildly vulnerable, vulnerable and very vulnerable.
