Input Sharing

Agglomeration, the spatial concentration of industries in a specific location, has been argued to improve productivity since it could provide positive externalities such as knowledge spillover, input sharing, and labor pooling. This paper examines the effect of large and medium manufacturing industry (LMI) agglomeration on labor productivity. Measuring the output and labor density as agglomeration effect by using 2009-2014 panel data from 44 cities and regions across the metropolitan areas of Indonesia, this study shows that in terms of output share, agglomeration positively contributes to labor productivity. On the other hand, in terms of labor density, agglomeration results in a negative impact on productivity. These findings suggest the government should expand industrial clusters in less densely populated areas, especially outside the island of Java, by providing necessary infrastructures such as electricity, ports, and roads, so that this development creates favorable economic conditions for investment and industrial development in such areas.

Agglomeration Effects

Agglomeration economies can arise in areas with high concentrations of firms, which can be facilitated by improved transportation accessibility. Accessibility can be improved by public transit infrastructure, especially in combination with careful planning for transit-oriented development (TOD) that creates compact, high density, mixed-use, and pedestrian-friendly built environments in proximity to public transit infrastructure. Although the literature on TOD has increasingly shown positive effects on residential development and property values, its effects on commercial and industrial development, location of firms, and associated agglomeration economies are less clear and require more empirical study. This study analyzes firm location patterns by industry/sector in the metropolitan area of Washington, DC and examines whether significant spatial clusters have developed in relation to: 1) the presence of Metrorail stations; and 2) the presence of specific industry firms in the earlier year, using kernel density analysis and multinomial logit (MNL) regression. The analysis results indicated that firms in certain industries, such as finance and insurance/real estate and public administration, are more likely to benefit from proximity to Metrorail stations than other industries. Furthermore, firms in several industries show the effects of agglomeration within the same industry while several combinations of industries exhibit cross-industry agglomeration effects. The findings of this study contribute to the understanding of which industry sectors are more likely to be located in proximity to rail transit stations and TOD areas and to the understanding of agglomeration effects within the same industry and between different industries.

AbstractAbility to quantify the amounts of N 2 fixed in agri-cultural land is critical to manage the N cycle for optimalfood and plantation crop production. Isotope and relatednuclear technique such as 15 N isotope dilution technique hasplayed a significant role in nutrient management analysis forquantification of biological N 2 fixation. The largest pool of Nin the environment is atmospheric N 2 and it has a constantnatural abundance of 0.3663 % atom15 N. 15 N is a stableisotope of N and used as a unique tracer to evaluate thepotential of N 2 fixing bacteria, especially symbiotic and non-symbiotic Rhizobacterium. A field experiment has beeninitiated at IBRIEC to assess the N 2 fixing capacity ofrhizobacterium isolated from sandy textured soil at CentralKalimantan and evaluate the potential of bacteria N 2 fixingon corn (Zea mays). Field experiment has been conducted atCiomas Research Station, IBRIEC-Bogor for four months.The field experiment has been organized according to themethod of Randomized Complete Blocks Design with sixtreatments and three replicates. The results of this studysuggested that the method was reliable for estimation of %Ndfa as well as quantitative analysis of the amount of N fixedfrom the atmosphare. The proportion of N 2 uptake derivedfrom the atmophere was estimated as 32% of the whole plantbasis which was equivalent to approximately 4.8 kg N/ha.The inoculation of Rhizobacterium increased dry matter ofcorn leaves, roots, and grains significantly.AbstrakKemampuan penetapan jumlah N 2 yang dapat ditambatpada lahan pertanian merupakan suatu hal yang penting untukmengatur siklus N sebagai upaya mencapai tingkat produk-tivitas yang optimal di tanaman pangan dan perkebunan.Teknik isotop atau yang berhubungan dengan teknologinuklir seperti isotop 15 N memiliki peran signifikan di dalammanagemen kebun berbasis nutrisi untuk mengkuantifikasipenambatan N 2 secara biologi. Cadangan N terbesar di dalamlingkungan adalah N 2 atmosfer.

The aim of this study was to show changes in labor productivity and concentration of production in the Polish food industry against the background of European Union countries and the indication of the causes (factors) which caused these changes. Poland's accession to the European Union has proved beneficial for the development of the Polish food industry. The dynamic development of production in this sector after 2004 has been accompanied by improved labor productivity, which is one of the main determinants of a company's competitiveness in the market. The assessment of changes in labor productivity was made at current prices, as well as at comparable prices, taking into account the purchasing power of currencies of individual member states. The method of compound interest was used to determine the average annual changes. In the years 2004-2014, labor productivity measured by the value of sold production increased in the Polish food industry (in comparable prices) from 141.2 to 225.3 thousand Euro/employee and was only about 10 percentage points lower than the EU-28 average. Importantly, productivity growth has occurred, although to a varying extent, in all sectors of the food industry in Poland. In the analyzed period, the number of food processing enterprises decreased in most EU-28 countries and the concentration of food production increased. Such changes have occurred in the largest EU-28 food producers, to which Poland is also counted.

Purpose. After radiofrequency ablation (RFA) of hepatocellular carcinoma (HCC), pre- and postinterventional contrast-enhanced CT (CECT) images are usually qualitatively interpreted to determine technical success, by eyeballing. The objective of this study was to evaluate the feasibility of quantitative assessment, using a nonrigid CT-CT coregistration algorithm. Materials and Methods. 25 patients treated with RFA for HCC between 2009 and 2014 were retrospectively included. Semiautomated coregistration of pre- and posttreatment CECT was performed independently by two radiologists. In scans with a reliable registration, the tumor and ablation area were delineated to identify the side and size of narrowest RFA margin. In addition, qualitative assessment was performed independently by two other radiologists to determine technical success and the anatomical side and size of narrowest margin. Interobserver agreement rates were determined for both methods, and the outcomes were compared with occurrence of local tumor progression (LTP). Results. CT-CT coregistration was technically feasible in 18/25 patients with almost perfect interobserver agreement for quantitative analysis (κ = 0.88). The interobserver agreement for qualitative RFA margin analysis was κ = 0.64. Using quantitative assessment, negative ablative margins were found in 12/18 patients, with LTP occurring in 8 of these patients. In the remaining 6 patients, quantitative analysis demonstrated complete tumor ablation and no LTP occurred. Conclusion. Feasibility of quantitative RFA margin assessment using nonrigid coregistration of pre- and postablation CT is limited, but appears to be a valuable tool in predicting LTP in HCC patients (p=0.013).
