description: Using high-resolution imaging with the Hubble Space Telescope, we study the Large Magellanic Cloud HII region N160A and uncover several striking features of this complex massive star-forming site. The two compact high excitation HII blobs (HEBs) A1 and A2 are for the first time resolved and their stellar content and morphology is revealed. A1, being of higher excitation, is powered by a single massive star whose strong wind has created a surrounding bubble. A2 harbors several exciting stars enshrouded inside large quantities of dust. The whole N160A nebula is energized by three star clusters for which we obtain photometry and study their color-magnitude diagram. The HII region is particularly dusty, with extinction values reaching an A_v~2.5 mag in the visible, and it is separated from the molecular cloud by an outstanding ionization front. A previously detected infrared young stellar object is also accurately located with respect to the HII region.

description: This paper shows that for the domain intersection $\dom T\cap\dom T^*$ of a closed linear operator and its Hilbert space adjoint everything is possible for very common classes of operators with non-empty resolvent set. Apart from the most striking case of a maximal sectorial operator with $\dom T\cap\dom T^*=\{0\}$, we construct classes of operators for which $\dim(\dom T\cap\dom T^*)= n \in \dN_0$; $\dim(\dom T\cap\dom T^*)= \infty$ and at the same time $\codim(\dom T\cap\dom T^*)=\infty$; and $\codim(\dom T\cap\dom T^*)= n \in \dN_0$; the latter includes~the case that $\dom T\cap\dom T^*$ is dense but no core of $T$ and $T^*$ and the case $\dom T=\dom T^*$ for non-normal $T$. We also show that all these possibilities may occur for operators $T$ with non-empty resolvent set such that either $W(T)=\dC$, $T$ is maximal accretive but not sectorial, or $T$ is even maximal sectorial. Moreover, in all but one subcase $T$ can be chosen with compact resolvent.

description: Reforestation of clear-cut areas has been considered one of the most critical topics of forest management in Estonia during the last 15 years. Experts have given alarming assessments especially about the situation in private forests. In the paper the use of different tools, implemented by forest authorities for the sake of reforestation has been analyzed. The results of National Forest Inventory and inventories made by the Centre Forest Protection and Silviculture have been used to describe the preliminary results in the forest. The intervention of government into forest management confined to legislation during the 1990ies but since the end of the century, financial instruments have also been used. It has been planned by the Ministry of Environment to implement a guarantee fund related to forest regeneration. Costs and benefits of creating such a guarantee fund were analyzed. Preliminary calculations indicated that long-term revenues and short-term costs were almost equal when taking into account all private forests. Authors suggest to link guarantee payments with financial incentives.

description: From a theoretical point of view, result-based agri-environmental payments are clearly preferable to action-based payments. However, they suffer from two major practical disadvantages: costs of measuring the results and payment uncertainty for the participating farmers. In this paper, we propose an alternative design to overcome these two disadvantages by means of modelling (instead of measuring) the results. We describe the concept of model-informed result-based agri-environmental payments (MIRBAP), including a hypothetical example of payments for the protection and enhancement of soil functions. We offer a comprehensive discussion of the relative advantages and disadvantages of MIRBAP, showing that it not only unites most of the advantages of result-based and action-based schemes, but also adds two new advantages: the potential to address trade-offs among multiple policy objectives and management for long-term environmental effects. We argue that MIRBAP would be a valuable addition to the agri-environmental policy toolbox and a reflection of recent advancements in agri-environmental modelling.

description: The impact of undergrowth and its pre-clearance methods on the productivity, costs, and silvicultural result of the winter and summer harvesting of first-thinning Scots pine (Pinus sylvestris) stands, and as well as the profitability of pre-clearance were analysed. The density and average height of the Norway spruce (Picea abies) undergrowth were found to have a significant impact on cutting productivity. Spruce undergrowth density also affected forwarding productivity. Undergrowth density, height, or pre-clearance method had no effect on the silvicultural result. The density and average height of the spruce undergrowth, the size of the trees to be harvested, the roundwood removal, and the costs for harvesting machinery used affected the calculated pre-clearance limits. The pre-clearance limit refers to the spruce undergrowth level, above which pre-clearance became economically profitable. Based on the findings of this study, when the spruce undergrowth density in a marked pine stand exceeds the pre-clearance limit, the most effective pre-clearance result is achieved when a one-metre radius is cleared around each merchantable stem together with any other spruce undergrowth over 1.5–2.0 m high that may hinder cutting.

description: In a recent paper, Elmegreen (2000) has made a cogent case, from an observational point of view, that the lifetimes of molecular clouds are comparable to their dynamical timescales. If so, this has important implications for the mechanisms by which molecular clouds form. In particular we consider the hypothesis that molecular clouds may form not by {\it in situ} cooling of atomic gas, but rather by the agglomeration of the dense phase of the interstellar medium (ISM), much, if not most, of which is already in molecular form.

description: Sweden and Finland as two neighbouring forestry countries are compared. Despite the widely similar features of forestry sectors, some interesting differences are found. In Finland, the economic dependence on and the people's involvement in the forestry sector are wider than in Sweden. For instance, there are almost double as many family forest owners in Finland as in Sweden. Decision making is more centrally organised in Finland than in Sweden. On the other hand, more normative control and general enhancement of rural entrepreneurship is employed in Sweden, whereas Finland relies more on direct financial support for rural sectors. The structural change in forest industry has progressed further in Finland than in Sweden and the dependence on imported wood is greater in Finland. The financing of nature conservation increased during the 1990's strongly in both countries and was on average at a slightly higher level in Finland than in Sweden. Since 1999, however, the conservation financing level has increased remarkably in Sweden. Eight out of ten of the general public in both Finland and Sweden see that forests are very or rather well managed. The impression is that forestry is practised slightly more intensive in Finland than in Sweden. Also the forestry net revenues have been since the end of 1990's higher in Finland.

Abstract: 

As part of our semantic data framework activities across disciplines from solid-earth, lower, middle and upper terrestrial atmosphere, and solar atmosphere, to integrative subjects such as climate response and space weather, we have collected a set of experiences: technical, collaboration and social that relate to how easy, or hard the infusion process has been. We cover both the semantic web and knowledge infusion as well as underlying service infusion such as catalogs and OPeNDAP data servers.

description: Previous studies have shown that the large, diffuse galaxies NGC1052-DF2 and NGC1052-DF4 both have populations of unusually luminous globular clusters as well as a very low dark matter content. Here we present newly-obtained deep Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) imaging of one of these galaxies, NGC1052-DF4. We use these data to measure the distance of the galaxy from the location of the tip of the red giant branch (TRGB). We find a rapid increase in the number of detected stars fainter than $m_{F814W} \sim 27.3$, which we identify as the onset of the red giant branch. Using a forward modeling approach that takes the photometric uncertainties into account, we find a TRGB magnitude of $m_{F814W,\rm TRGB}=27.47 \pm 0.16$. The inferred distance, including the uncertainty in the absolute calibration, is $D_{\rm TRGB}=20.0 \pm 1.6$ Mpc. The TRGB distance of NGC1052-DF4 is consistent with the previously-determined surface brightness fluctuation distance of $D_{\rm SBF}=18.7\pm 1.7$ Mpc to NGC1052-DF2 and is consistent with the distance of the bright elliptical galaxy NGC1052. We conclude that the unusual properties of these galaxies cannot be explained by distance errors.

description: We propose to probe the topcolor-assisted technicolor (TC2) model from the top-charm associated productions at the LHC, which are highly suppressed in the Standard Model. Due to the flavor-changing couplings of the top quark with the scalars (top-pions and top-Higgs) in TC2 model, the top-charm associated productions can occur via both the s-channel and t-channel parton processes by exchanging a scalar field at the LHC. We examined these processes through Monte Carlo simulation and found that they can reach the observable level at the LHC in quite a large part of the parameter space of the TC2 model.

description: We give a global version of Le-Ramanujam mu-constant theorem for polynomials. Let f_t, (t in [0,1]), be a family of polynomials of n complex variables with isolated singularities, whose coefficients are polynomials in t. We consider the case where some numerical invariants are constant (the affine Milnor number, the Milnor number at infinity, the number of critical values, the number of affine critical values, the number of critical values at infinity). Let n=2, we also suppose the degree of the f_t is a constant, then the polynomials f_0 and f_1 are topologically equivalent. For n>3 we suppose that critical values at infinity depend continuously on t, then we prove that the geometric monodromy representations of the f_t, are all equivalent.

description: International agri-food trade has expanded rapidly during the past decades and changed considerably in structure with important implications especially for developing economies. One of the main environmental concerns regarding international trade is about the exploitation and redistribution of water resources. In this paper we use the virtual water approach for analyzing the relation between global agri-food trade, its structure and virtual water flows in the period of 1986 to 2011. Specifically, for five world regions we calculate growth rates of interregional trade values and virtual water volumes, the contribution of different product groups to trade and the economic water efficiency of imports and exports. Our findings show that over time trade values have generally increased more rapidly than virtual water volumes. In Africa and South America virtual water exports have roughly quadrupled since 1986. In all regions staples and industrial products account for the largest share in virtual water trade. The recent shift towards high-value exports is beneficial for developing countries from a regional water efficiency perspective due to high trade values and low associated virtual water volumes. Water efficiency of trade has increased in all regions since 2000 and export water efficiency is especially high in Europe.

description: We assess the literature on public and private quality standards and their impact in food markets, international trade, and global supply chains. We focus on their effects on welfare, trade, industrial organization, and labor markets and with special attention to the North-South context. We also attempt to better characterize when these measures constitute protectionism, a complicate task. We look at studies investigating public and private standards and across various quantitative approaches and countries. These standards have complex effects. The evidence is mixed regarding standards as catalyst for or impediment against trade and development, reflecting the complexity of these effects and their specificity to industries and countries. The analysis of standard-like nontariff measures and their impacts does not lead to sweeping prescriptions for policy reforms. We identify more modest prescriptions and make some recommendations for fruitful research directions.

description: Fimbriae play an important role in adhesion and are therefore essential for the interaction of bacteria with the environments they encounter. Most of them are expressed in vivo but not in vitro, thus making difficult the full characterization of these fimbriae. Here, we characterized the silencing of plasmid-encoded fimbriae (Pef) expression, encoded by the pef operon, in the worldwide pathogen Salmonella Typhimurium. We demonstrated that the nucleoid-associated proteins H-NS and Hha, and their respective paralogs StpA and YdgT, negatively regulate at pH 5.1 and pH 7.1 the transcription of the pef operon. Two promoters, PpefB and PpefA, direct the transcription of this operon. All the nucleoid-associated proteins silence the PpefB promoter and H-NS also targets the PpefA promoter. While Hha and YdgT are mainly considered as acting primarily through H-NS to modulate gene transcription, our results strongly suggest that Hha and YdgT silence pef transcription at acidic pH either by interacting with StpA or independently of H-NS and StpA. We also confirmed the previously described post-transcriptional repression of Pef fimbriae by CsrA titration via the fim mRNA and CsrB and CsrC sRNA. Finally, among all these regulators, H-NS clearly appeared as the major repressor of Pef expression. These results open new avenues of research to better characterize the regulation of these bacterial adhesive proteins and to clarify their role in the virulence of pathogens.

description: The study was conducted to examine the income and price elasticities of demand for different types of rice in Bangladesh. Both time series and cross-section data were used to estimate a complete demand system equation. The equation was estimated in three stages to obtain income and price elasticies of demand for rice. The stages were the allocation of household total income on food and non-food items, the allocation of household total food expenditure for cereal, and the allocation of household total cereal expenditure on different types of rice and wheat, respectively. The total budget for cereal food allocated to aromatic, fine, coarse rice, and wheat was 4.0%, 23.3'70, 65.2%, and 7.5%, respectively. The estimated expenditure elasticities of demand for those types of cereals Here 0.85. 0.79. 0?9, and 0.55. respectively. The expenditure elasticities of demand for aromatic and coarse rice were higher for rural households compared with urban households, while the expenditure elasticities of demand for fine rice and wheat were higher for urban households. Considering all other factors remaining unchanged, the uncompensated and compensated own-price elasticities of demand for coarse rice would fall by 7.7% with a 10% increase in its price. These falls were 7.4%, 11.170, and 4.6% for aromatic, line rice, and wheat, respectively. The estimates of uncompensated cross-price elasticities between coarse-to-fine rice showed that a 10% increase in absolute income associated with a 10% increase in real income due to fall in coarse rice price would increase the actual demand for fine rice by 4.6%. A 10% increase in absolute income accompanied by a l07 increase in real income due to fall in coarse rice price would increase the actual demand for aromatic rice and wheat by 7.4% and 4.6%, respectively.

description: Background: The prevalence of overweight (OWT) and obesity (OB), defined by the body mass index (BMI, kg/m2) among children and youth has increased worldwide in the last 30–40 years. Aim: To evaluate the weight status, defined by the BMI, of indigenous school children and youth resident in different regions of Mexico Subjects and methods: Students 6–18 years (31,448 boys, 27,306 girls) were enrolled in bilingual schools for indigenous children and youth in Mexico in 2012. Height and weight were measured; the BMI was calculated. The BMI of each student was classified relative to International Obesity Task Force (IOTF) age- and sex-specific criteria as thin (three grades), normal, overweight (OWT) or obese (OB). The sample was divided into five geographic regions for analysis: North, Central, South-Gulf, South-Pacific, and South-Southeast. Age- and sex-specific prevalence, 95% confidence intervals, and Chi-square tests were calculated. Results: Prevalence of OWT + OB was highest in the South-Gulf, South-Pacific and South-Southeast regions and lowest in the North and Central regions, while thinness was most prevalent in the North and Central regions. Conclusion: Prevalence of severe and moderate thinness was relatively low, while the combined prevalence of OWT + OB was generally more prevalent in indigenous boys than girls. However, the prevalence of thinness, OWT + OB among indigenous children and youth was lower than in the general population of children and youth in Mexico.

description: We present the first edition of a catalog of variable stars found in the Magellanic Clouds using OGLE-II data obtained during four years: 1997-2000. The catalog covers about 7 square degrees of the sky - 21 fields in the Large Magellanic Cloud and 11 fields in the Small Magellanic Cloud. All variables were found with the Difference Image Analysis (DIA) software. The catalog is divided into two sections. The DC section contains FITS reference images (obtained by co-adding 20 best frames for each field) and profile photometry (DoPHOT) of all variable stars on those images. The AC section contains flux variations and magnitudes of detected variable stars obtained with DIA as well as with DoPHOT. The results are available in electronic form via FTP and through WWW interface from the OGLE internet archive. Typically, there are about 400 I-band data points and about 30 V and B-band data points for over 68,000 variables. A detailed analysis and classification of variable stars will be presented elsewhere. The FTP catalog contains approximately 2Gbytes of data.

description: Myeloid cell leukemia-1 (Mcl-1) is an anti-apoptotic member of the Bcl-2 family proteins. Its amplification is one of the most frequent genetic aberrations found in human cancers. Pyridoclax, a promising BH3 mimetic inhibitor, interacts directly with Mcl-1 and induces massive apoptosis at a concentration of 15 µM in combination with anti-Bcl-xL strategies in chemo-resistant ovarian cancer cell lines. In this study, a combined experimental and theoretical approach was used to investigate the binding mode of Pyridoclax to Mcl-1. The representative poses generated from dynamics simulations compared with NMR data revealed: (i) Pyridoclax bound to P1 and P2 pockets of Mcl-1 BH3 binding groove through its styryl and methyl groups establishing mainly hydrophobic contacts, (ii) one of the ending pyridines interacts through electrostatic interaction with K234 side chain, a negatively charged residue present only in this position in Mcl-1.

description: We discuss the relation between matrix models and the Seiberg--Witten type (SW) theories, recently proposed by Dijkgraaf and Vafa. In particular, we prove that the partition function of the Hermitean one-matrix model in the planar (large $N$) limit coincides with the prepotential of the corresponding SW theory. This partition function is the logarithm of a Whitham $τ$-function. The corresponding Whitham hierarchy is explicitly constructed. The double-point problem is solved.

description: This paper examined the pattern of economic growth during 1991 to 2005 in order to assess the role of agriculture in promoting equitable growth in Bangladesh. In particular the paper examined the strength of the channel through which agricultural growth benefits the poor by increasing their income and identified the measures that could bring a more pro-poor agricultural growth in the country. This paper also examined the poverty trends in the 1990s and the income profile of the poor to identify their major income sources. The paper assessed the growth performance of the economy during 1991 to 2005 and examined the relative strength of the linkages of agricultural growth with the incomes of the poor through sectoral and labour market channels. Some policy implications to strengthen agricultural growth-poverty linkages are also presented in this study.

description: Based on national level data from secondary sources, changes in production variability and their sources of changes for Bangladesh as a whole were measured for major foodgrains- Aus, Aman and Boro rice as well as wheat during 1979/80 to 1998/99 which were again sub-divided between two time periods before full-implementation of privatization policies (1979/80-1988/89) and after fullimplementation of privatization policies (1989/90-1998/99). The results showed that during the period after full-implementation of privatization policies (AFIPP) both the absolute variability (Standard Deviation, SD) and relative variability (coefficient of variation, CV) ipcreased in the cases of Aus rice, Arran rice and wheat production. Absolute variability increased but relative variability decreased in the cases of Boro rice and total foodgrains production. The increase in CV of Aman rice and wheat production is due to increase in both SD and average production of Aman rice and wheat. The increase in relative variability of Aus rice is due to increase in absolute variability and decrease in average production of Aus rice. The decrease in CV of Boro rice and total foodgrains production is attributed to increase in both SD and average production of Boro rice and total goodgrains. The results also showed that in the cases of Aus and Boro rice change in mean area: in the cases of Aman rice and total foodgrains change in mean area variance, and in the case of wheat change in yield variance contributed largely to change in production variance. Inter-regional covariance is the largest contributor to change in production variance of Aus rice, Boro rice, wheat and total foodgrains between the period before and after full implementation of privatization policies. In the case of Aman rice, Rangpur region is the largest contributor to change in production variance.

description: We study AdS$_3\times \text{S}^2$ solutions in massive IIA that preserve small ${\cal N}=(4,0)$ supersymmetry in terms of an SU(2)-structure on the remaining internal space. We find two new classes of solutions that are warped products of the form AdS$_3\times \text{S}^2\times \text{M}_4\times \mathbb{R}$. For the first, M$_4$=CY$_2$ and we find a generalisation a D4-D8 system involving possible additional branes. For the second, M$_4$ need only be Kahler, and we find a generalisation of the T-dual of solutions based on D3-branes wrapping curves in the base of an elliptically fibered Calabi-Yau 3-fold. Within these classes we find many new locally compact solutions that are foliations of AdS$_3\times \text{S}^2\times\text{CY}_2$ over an interval, bounded by various D brane and O plane behaviours. We comment on how these local solutions may be used as the building blocks of infinite classes of global solutions glued together with defect branes. Utilising T-duality we find two new classes of AdS$_3\times \text{S}^3\times \text{M}_4$ solutions in IIB. The first backreacts D5s and KK monopoles on the D1-D5 near horizon. The second is a generalisation of the solutions based on D3-branes wrapping curves in the base of an elliptically fibered CY$_3$ that includes non trivial 3-form flux.

description: This is a study of functioning of selected commodity markets in terms of price relationship to each other. Spatial price integration has been assessed for crops viz. Aman (HYV), Boro (HYV), wheat, mustard and lentil in selected districts firstly, by one to one correlation matrix and secondly by the Augmented Dickey-Fuller co-integration test. District-wise market prices of the crops were collected from the Department of Agricultural Marketing (DAM) for the period of 1986-2005. Aman HYV markets were well integrated but the Boro HYV markets were not well integrated. Wheat markets were not all (48 percent) interdependent in price formations but peak prices season flour markets became largely integrated. Out of 21 paired markets, only 7 paired markets were integrated for unprocessed lentil and 10 paired markets were integrated after processing. Seventeen market pairs are significantly correlated during harvest season of mustard (whole). And all the correlation coefficients appeared significant for mustard oil. Markets were more inter-linked during the period of scarcity and more integrated for processed primary products. Level of market integration has improved than any time before the study period. Integrated markets in general imply policy formulation at macro level will be effective throughout all trading markets. But extent of market integration of the same commodity during harvest time and pre-harvest season and segmented any particular region has to be taken into consideration for fine tuning of agricultural policies attaining more success.

description: The role of digitalization in the banking sector has altered customers’ preferences. As a result of this, banks in Nepal are becoming more digitally oriented in order to satisfy their customers’ new demands. According to the contingency theory, the banks’ new digital focus has to be aligned with other factors in the banks in order for them to function effectively. In a country like Nepal, which already has a slew of issues, the path to establishing a vibrant digital payments ecosystem is certain to encounter some legitimate worries and hurdles. This study investigated how the banks’ relationship with customers is affected by this digital focus. This is a qualitative study that has been conducted through a case study at a large Fintech and Digital Banking industry in Nepal. The data gathered in the case study indicate that the relationship with customers has become less personalized and more automated. It also shows that an alignment in the bank has contributed to increased satisfaction among digitally oriented customers. Digitalization has impact on all segments of society, particularly on the economy and business. Digital transformation opens new unforeseen possibilities and new business activities for companies that lead to the new forms of firm relationships with its customers and employees, transformation of its business processes and the creation of new business model. Digital technology as the main driver of changes is at the epicenter of digital transformation. As digitalization is important topic for many businesses today, this master thesis explores the impact of digitalization on companies’ business model and how different digital technology shapes digital transformation process of companies in banking industry of Nepal. The study used a mixed methods approach, utilizing bank financial reports, Digital Banking and PSO/PSP related data interviews and questionnaires to achieve important results and contribute to knowledge in practice, and in related services, marketing and e-commerce theories. The research adopted regression and Chi-Square analyses in quantitative research, while using Content Analysis in qualitative research. The research takes a broad approach in the investigation of digital banking, customer experience and bank financial performance. It has used qualitative and quantitative analysis techniques to produce, test and triangulate results to increase robustness. The study is significant to the banks and financial institutions customers, stake holders and to the existing body of knowledge and literature related to Financial Technology and Digital Banking services. The result enabled the supervision body- the Central bank, to understand the current issue on Financial Technology and Digital Banking.

description: The study was conducted at the districts namely Rangpur, Comilla, Tangail, and Narshingdi during 2003 for estimating the profitability of exportable vegetables production and identifying the factors influencing their production. The vegetables were French bean (FB), yard long bean (YLB) and bitter gourd MG). In total, 224 purposively selected vegetable farmers were interviewed for collecting. The study revealed that the commercial production of above vegetables was profitable both on cash cost and full cost basis. Per acre net returns for FB, YLB and BG were Tk. 8,107, Tk. 13,117 and Tk. 22,344 on full cost respectively. The estimated BCR for FB, YLB and BG were 1.22, 1.36, and 1.63 on full cost respectively. The output elasticity of land preparation, seed, manure & fertilizer, irrigation, and farm size were positive and significant implying that vegetable production could be increased through balanced application of inputs.
Classical and quantum quintessence cosmology

description: This paper implements the idea of considering the instantonic creation of brane worlds whose five-dimensional bulk contains a negative cosmological constant and a scalar quintessence field with time-dependent equation of state, restricting to the case that the quintessence field couples minimally to Hilbert-Einstein gravity. We construct an Euclidean formalism, both for the four- and five-dimensional cases, singling out a Hamiltonian constraint that depends on the parameter defining the quintessence state equation. Specializing at several particular values of that parameter, we obtain solutions to the constraint equation and analyse them both classically and quantum mechanically. It is found that these solutions can represent either asymptotically anti-de Sitter wormholes or pure anti-de Sitter spaces whose quantum states are obtained by means of the Wheeler de Witt equation. Starting with the different five-dimensional solutions, an instantonic procedure is applied to describe the creation of geometrically equivalent inflating de Sitter branes whose quantum states are also evaluated in some cases. We thus consider the quantum state of the universe to be contributed by all the instantonic paths that correspond to these particular brane worlds.

description: We show how the problem of small neutrino masses and suppressed proton decay can be simultaneously resolved in 6-D universal extra dimension models (UED) with a low fundamental scale using extended gauge groups that contain the local $B-L$ symmetry. The extra space dimensions are compactified either on a $T^2/Z_2$ or $T^2/Z_2\times Z'_2$ orbifold depending on whether the full gauge group is $SU(2)_L\times U(1)_{I_{3R}}\times U(1)_{B-L}$ or $SU(2)_L\times SU(2)_{R}\times U(1)_{B-L}$. In both cases, neutrino masses are suppressed by an appropriate orbifold parity assignment for the standard model singlet neutrinos and the proton decay rate is suppressed due to a residual discrete symmetry left over from compactification. For lower values of the fundamental scale, a dominant decay mode of the neutron is $n\to 3 ν$. An interesting consequence of the model is a possible two component picture for dark matter of the universe.

description: This siudti- is concerned with the estimation of technical efficiency of the hatchery operators producing fish seed Using 56 samples comprising 15 from Jessore, 10 from Chandpur, 16 from Bogra, and 15 from Siymensingh districts, the study has used frontier 4.1 Package to estimate the technical efficiency of the hatchery operators. A Cobb-Douglas type production function with nine quantitative variables namely. pond area, human labour, feed, fertilizer, number of brood fish, number of times brood used in a year, fuel electricity and hormone dose given to female brood and a dummy for stochastic frontier and a linear technical inefficiency function with 4 variables: Age, Education, Experience and Training received by the hatchery operator were estimated. Several hypotheses tests were performed using Log-likelihood Ratio Test. The mean technical efficiency of the hatchery operators was 60 percent. Technical efficiency were not found to be skewed towards higher or lower scores. rather concentrated in the 30'h, 40`", 60"' and 90°i percentiles. Hypothesis of existence of inefficiency effect was rejected establishing that significant inefficiency exists. More than one third of the seed production potential remains unutilized. Utilizing the unexploited production potential of the fish seed producers rather than establishing new farms and hatcheries appears to be the pertinent policy. Training of the farm hatchery operators can help achieve the unexploited potential.
