Value Chain Analysis of Apple in Shimla District of Himachal Pradesh, India

The study sought to acquire extensive insights into the markets and associated marketing strategies within the Shimla district during the year 2021-22. Employing a random sampling technique, a representative sample comprising five traders, five wholesalers, five retailers, and thirty actively engaged consumers in the apple marketing sector was selected. The investigation identified the presence of five distinct marketing channels in the study area. Channel-V, which involves the processing of apples into value-added forms such as jam, wine, and juice, exhibited the most substantial degree of value addition, contributing 55.80 percent to the overall value addition. In the study area, the majority of farmers acquire their inputs from private institutes. A methodically prepared value chain map illustrates the continuous transfer of produce from farmers to consumers. Notably, the wholesale stage experienced the most significant loss, amounting to 4.11 kg per quintal. In the storage of apples, the storage unit gained a profit of 140 Rs per kg, while in the processing of apples, the processing unit it was 13333.59 Rs. per quintal.

Piggery Value Chain Mapping in Bengaluru: A Comprehensive Analysis of Rearing Systems

The study examines the piggery value chain in Bengaluru, focusing on 35 breeders and fattening farmers across Bengaluru rural and Bengaluru urban areas. It analyses distinct rearing systems, breeding practices, feeding strategies, and healthcare protocols among respondents. Breeders predominantly utilize intensive rearing systems (100%) for optimized breeding outcomes, while fattening farmers prefer semi-intensive methods (85.71%) to balance care with natural behaviours. Variations in housing preferences show that 46.67 per cent of fattening farmers use efficient drainage systems compared to none among breeders. Feeding practices differ significantly 100 per cent of breeders employ stall feeding, whereas 75 per cent of fattening farmers practice scavenging feeding with 25 per cent engaging in mixed feeding. Feeding frequency is consistently twice daily among all respondents (100%). The deworming practices at 45.71 per cent overall, with 100 per cent among breeders and 60 per cent among fattening farmers. Vaccination is practiced exclusively by breeders (100 %). Veterinary aid satisfaction rates are 31.43 per cent overall, with 40 per cent among fattening farmers. A detailed value chain map visually depicts stages from input supply to consumption, elucidating stakeholder roles crucial for productivity enhancement, animal welfare promotion, and sustainable practices within Bengaluru's piggery sector.

Identifying, Mapping, and Analyzing Stakeholders of Tomato Value Chain

The research aims to optimize the efficiency of tomato value chain by mapping and analyzing various stakeholders. The study was taken as a part of the Research work of MBA (Agribusiness) carried out at Madanapalli taluka of Chittoor district in Andhra Pradesh. The complete research design work is based on primary and secondary data collected through a structured questionnaire and from the Madanapalli Agriculture Produce Marketing Committee, annual reports of the National Horticultural Board, and articles from the World Processing Tomato Council. A multistage sampling technique was used for selection and Descriptive statistics, value chain analysis was carried out to identify the key activities within the industry. A value chain map illustrates the journey of tomatoes from production to the consumer, highlighting the various stages and processors involved along the way. The connections are displayed in a vertical manner from the left to the right side. At the top, the main functions of the chain are listed. These functions encompass input supply, production, trading, marketing/processing, and consumption. The vertical progression from the left to the right side illustrates the individuals engaged in performing the various functions. Displayed on the left side, the enablers help and support the actors in performing their roles. These enablers primarily include formal and informal institutions, as well as private organizations. The study concludes that lack of access to credit, Huge loss of raw produce in a glut situation, Inadequate infrastructure, seasonal fluctuations in business, and intense competition within a limited timeframe pose significant challenges in the tomato value chain. The lack of incentives for quality differentiation further exacerbates these issues. The chain's lack of transparency allows middlemen to wield control, leaving farmers with little ability to market their produce effectively.

THE ALGORITHM OF RISKS IDENTIFICATION IN THE OPERATING MODEL

The main purpose of creating an operational model is to ensure the synchronization of the organization's strategy and operational functions. The algorithm of the operating system can be represented as a hierarchical sequence of optimization processes aimed at achieving the final goal - value chain map. The operating system of an individual organization has its own process and parametric features that distinguish it from others. The risk factors will reflect these differences and the methods of their prediction and compensation should also be adapted to the specifics of the operating systems. It is impossible to optimize the operating model, to ensure the economic stability of the organization, ignoring objective and subjective sources of risks. Exclusion of risk parameters of operational processes directly affects the overall efficiency of the operational system, reduces uncertainty and unwanted fluctuations in the quality indicators of the operational model. The article examines the hierarchical algorithm of risk identification in the operational model of the organization.

Wood-products value-chain mapping

ABSTRACT With the increasing importance of wood as a sustainable material and addressing challenges facing the wood products industry, there is an emerging need for innovation and collaboration across all industry sectors. The mapping of the wood products industry has become crucial for gaining an overview and overall understanding of material flow. It also proved beneficial for educational and research purposes. The outcome of this study should help seek new economic opportunities and promote sustainable resource management. A Generic Map was developed to navigate the entire wood products industry as well as Dive-in Chain Maps will guide the four major production chains: sawmill (I), veneer mill (II), reconstituted wood manufacturing (III), and pulp and paper mills (IV). In addition, a By-products Management Wheel Diagram was introduced to clarify waste management practices within these chains. Our approach sheds light on efficient material flow and utilization, revealing opportunities for innovation and the development of high-value products. It also offers strategies for minimizing waste and making informed end-of-life decisions. Ultimately, this study enhances the understanding and potential for circularity and sustainability in the wood products industry.

Central limit theorem for euclidean minimal spanning acycles

In this paper, we investigate asymptotics for the minimal spanning acycles (MSAs) of the (Alpha)-Delaunay complex on a stationary Poisson process on [Formula: see text]. MSAs are topological (or higher-dimensional) generalizations of minimal spanning trees. We establish a central limit theorem (CLT) for total weight of the MSA on a Poisson Alpha-Delaunay complex. Our approach also allows us to establish CLTs for the sum of birth times and lifetimes in the persistent diagram of the Delaunay complex. The key to our proof is in showing the so-called weak stabilization of MSAs which proceeds by establishing suitable chain maps and uses matroidal properties of MSAs. In contrast to the proof of weak-stabilization for Euclidean minimal spanning trees via percolation-theoretic estimates, our weak-stabilization proof is algebraic in nature and provides an alternative proof even in the case of minimal spanning trees.

Domestic midscale chain hotel brands' effectiveness in research and development: An exploratory study

AbstractWhile many midscale chain hotel brands in China's domestic market have developed rapidly since 2010, it is still unclear how a new midscale chain hotel brand can be most effectively researched and developed. Drawing from resource‐advantage theory, this study aimed to understand the effectiveness of six key attributes of new domestic midscale chain hotel brands and map them onto a research and development (R&D) competitive position matrix. The results show that the actual R&D process lasts beyond the opening of the first hotel of the new brand and requires a further 2‐year maturation period. This study contributes to the literature by creating a maturation system that could play a key role in the effectiveness of the R&D underlying a chain hotel's brand development. It also provides a compelling tool for monitoring the effectiveness of domestic midscale chain hotel brands' R&D.

Derivation analysis of a discrete-time SIS epidemic model with extension of Markov Chain and logistic map

In recent years, the rampant spread of diseases has led to considerable impacts on human society. Limiting such spread requires the formulation of quantitative studies to understand the dynamics of infection and to study the effect of preventative and counteractive action. In 1911, scientists constructed differential equations to study the spread of malaria and found that at a critical mosquito population level the spread of the disease would be limited. This also became the basis for the later dynamics of infectious diseases. This research aims to dynamically analyze the spread of the virus by establishing a mathematical model and assigning specific values to the influencing factors to discuss the relationship between the person who infects others and the infected person. The ultimate goal is that the spread of the disease can be effectively suppressed in a specific proportion of people.
 Keywords: dynamics of infectious diseases, infected-uninfected relationship.

Value Chain Map of Coffee Commodities in Central Aceh Regency in the Implementation of Inclusive Business Model

This study aims to describe the Value Chain of coffee commodities in Central Aceh Regency and analyze the Value Chain Map of coffee commodities in Central Aceh Regency in the implementation of the Inclusive Business Model. This research was conducted in Central Aceh District, Aceh Province. This research was conducted in March–August 2023. The data used is in the form of primary data and secondary data. The sampling method with non-probability sampling uses the purposive sampling method. The data analysis method used is qualitative data analysis. Data analysis techniques use the Value Chain Map approach. The value chain of coffee in Central Aceh Regency the first distribution pattern is farmers selling directly to middlemen to exporters and consumers, the second pattern is farmers to middlemen to cooperatives and consumers, then the third pattern is farmers to middlemen to MSMEs Coffee Processors and consumers. The implementation of an inclusive business model for coffee commodities in Central Aceh Regency is through a partnership or collaboration between coffee farmers and the Baitul Qiradh Baburrayyan Cooperative. The highest value for farmers who are members of cooperatives is in principle 2 of effective market linkage (3.8). The lowest value is principle 3 fair and transparent governance (3.0). The highest value in non-cooperative farmers is principle 1 chain-wide collaboration (2.5). The lowest value is the 6 principles of Measurement of outcome (2.0). The inclusive business model is very profitable for farmers who join cooperatives because farmers get premiums, higher prices, infrastructure development, coaching and capital to improve farmer welfare.

The development of the digital economy in the modern era significantly embodies a country’s comprehensive strength. This paper uses the data from China’s 2012 and 2017 input-output tables to analyze the linkage structure between the digital economy industry and other industries using the average propagation length model and social network analysis. The Weaver–Thomas model was used to obtain the industrial linkage matrix and network characteristics. An industrial chain map of the digital economy was depicted as the core. This paper is of practical significance in depicting the industrial chain structure and network characteristics, understanding the position of digital economy industry in the economic system and promoting the integrated development of the digital economy and traditional manufacturing industries, which allows them to incorporate the new generation of technology and industrial transformation with the digital technology as the core to promote their transformation and upgrading.

An assessment of the structure of shea global value chain in Ghana and implication for policy development

The global value chain for shea has witnessed major transformations in the last two decades. This study was aimed at providing a detailed understanding of the structure of the shea value chain in Ghana. Data were collected primarily from primary source and secondary sources. A total of 820 upstream actors, 20 aggregators, 2 processing companies and other experts were interviewed using both closed-ended and open-ended questionnaires to gather qualitative and quantitative data. The study employed the value chain framework to analyse the structure of the shea value chain in Ghana. Data analysis was primarily descriptive in nature. A value chain map, schematic diagram, and flow charts were generated to show the linkages between actors and the flow of resources, materials, products, information, and funds. The results show that the shea value chain is highly gendered, with women at the base of the chain, working as shea kernel producers and processors of crude shea butter, using mainly traditional methods, hence output is sub-optimal. The mid-stream actors were all males, whose main function involves aggregating shea kernels across several communities for industrial processors and export companies. Processing companies, using mechanised methods, process and export several derivatives of shea (shea grits, shea butter, stearin, and olein) to mainly to high-end markets in the E.U and Asia. Though female participation in the shea global value chain is prominent, their output is way too low at the current level to make significant impact. Policy focus must be on supporting upstream actors through the provision of improved processing facilities, community infrastructure, and skills training to enhance the capacity of upstream actors to improve their performance.

Preprojective algebras of d-representation finite species with relations

In this article we study the properties of preprojective algebras of representation finite species. To understand the structure of a preprojective algebra, one often studies its Nakayama automorphism. A complete description of the Nakayama automorphism is given by Brenner, Butler and King when the algebra is given by a path algebra. We generalize this result to the species case.We show that the preprojective algebra of a representation finite species is an almost Koszul algebra. With this we know that almost Koszul complexes exist. It turns out that the almost Koszul complex for a representation finite species is given by the mapping cone of a chain map, which is homogeneous of degree 1 with respect to a certain grading. We also study a higher dimensional analogue of representation finite hereditary algebras called d-representation finite algebras. One source of d-representation finite algebras comes from taking tensor products. By introducing a functor called the Segre product, we manage to give a complete description of the almost Koszul complex of the preprojective algebra of a tensor product of two species with relations with certain properties, in terms of the knowledge of the given species with relations. This allows us to compute the almost Koszul complex explicitly for certain species with relations more easily.

Iterated integrals with values in Azumaya algebras

We define Chen’s iterated integrals of forms with values in an Azumaya algebra and show that in the flat case, these iterated integrals provide chain maps, and more generally, the curved structure is preserved. The appropriate trace maps are then defined and their corresponding geometric meanings are studied. We also define and study the wedge product of forms and the concatenation product of paths for these iterated integrals.

BRST cohomology is Lie algebroid cohomology

In this paper we demonstrate that the exterior algebra of an Atiyah Lie algebroid generalizes the familiar notions of the physicist's BRST complex. To reach this conclusion, we develop a general picture of Lie algebroid isomorphisms as commutative diagrams between algebroids preserving the geometric structure encoded in their brackets. We illustrate that a necessary and sufficient condition for such a diagram to define a morphism of Lie algebroid brackets is that the two algebroids possess gauge-equivalent connections. This observation indicates that the aforementioned set of Lie algebroid isomorphisms should be regarded as equivalent to the set of local diffeomorphisms and gauge transformations. Moreover, a Lie algebroid isomorphism being a chain map in the exterior algebra sense ensures that isomorphic algebroids are cohomologically equivalent. The Atiyah Lie algebroids derived from principal bundles with common base manifolds and structure groups may therefore be divided into equivalence classes of isomorphic algebroids. Each equivalence class possesses a local representative which we refer to as the trivialized Lie algebroid, and we show that the exterior algebra of the trivialized algebroid gives rise to the BRST complex. We conclude by illustrating the usefulness of Lie algebroid cohomology in computing quantum anomalies, including applications to the chiral and Lorentz-Weyl (LW) anomalies. In particular, we pay close attention to the fact that the geometric intuition afforded by the Lie algebroid (which was absent in the naive BRST complex) provides hints of a deeper picture that simultaneously geometrizes the consistent and covariant forms of the anomaly. In the algebroid construction, the difference between the consistent and covariant anomalies is simply a different choice of basis.

Value Chain analysis of underutilized economically potential plants in Sri Lanka: A special reference to <em>Moringa oleifera</em>

Although Moringa oleifera is identified as a nutrient-dense, superfood with increasing demand in the international market, it is recognized as an underutilized plant in Sri Lanka with vast potential to improve rural income. Thus, the objective of this study is to identify the existing potential of the plant, to act as an income generator. Value chain analysis was done qualitatively, in order to map the existing value and to identify main actors, channels and constraints along value chains. Dry and intermediate ecological zones were selected and a total of 47 participants were drawn purposively, and interviewed through face-to-face interviews and telephone conversations in order to gather primary data needed. Two value chain maps were identified related to leaf and pod – based products and exporters add a considerably higher amount of value to products. Leaf collector was identified as an actor who arbitrary gains higher profits with a little value addition. It is concluded that even though there is a high potential and return for M. oleifera based products, the communication gap among actors in the value chain and lack of awareness among local consumers hinder the possible income generation.

Value chain analysis of carp fish seed farms in some selected areas of Mymensingh district in Bangladesh

This study is an attempt to analyze the prevailing value chain of fish seed farms in some selected areas of Mymensingh district in Bangladesh. Data were collected from 280 fish seed farms owners (56) and traders (224) covering four Upazilas of Mymensingh district namely Mymensingh Sadar, Gauripur, Muktagacha, and Trishal from the period of July 2019 to October 2019 through purposive random sampling technique. Three important fish seed species of carp; namely Rui, Catla, Mrigel were selected to address the following objectives: typical value chain map and marketing system of fish seed farms, determination of the net value addition of fish seed production and marketing, and problems impacting different actors in the value chain. Total net marketing margin per 10 Kg. spawn and per 100000 pieces’ fingerlings are Tk. 20204 (190.43 USD) and Tk. 43148 (406.69 USD), respectively. Among all three intermediaries, the net marketing margin of the retailer is the highest. A large percentage of value addition is covered by paiker for both cases and that is 20.85% and 31.2%. The study finds that fish seed farms with hatcheries are more profitable than fish seed farms with nursery. The yearly net return from spawn production in the hatchery is Tk. 4324775 (40763.15 USD) and from fingerling production in the nursery is Tk. 2388126 (22509.27 USD). The owners and traders have currently been facing some difficulties. Lack of information about good quality seed, the higher price of inputs, and lack of extension service is some of the examples. If these problems could be solved, fish seed farms and market intermediaries could earn a higher profit than the existing level.

A geometric interpretation of Ranicki duality

Consider a commutative ring $R$ and a simplicial map, $X\mathop {\longrightarrow }\limits ^{\pi }K,$ of finite simplicial complexes. The simplicial cochain complex of $X$ with $R$ coefficients, $\Delta ^*X,$ then has the structure of an $(R,K)$ chain complex, in the sense of Ranicki . Therefore it has a Ranicki-dual $(R,K)$ chain complex, $T \Delta ^*X$ . This (contravariant) duality functor $T:\mathcal {B} R_K\to \mathcal {B} R_K$ was defined algebraically on the category of $(R,K)$ chain complexes and $(R,K)$ chain maps. Our main theorem, 8.1, provides a natural $(R,K)$ chain isomorphism: \[ T\Delta^*X\cong C(X_K) \] where $C(X_K)$ is the cellular chain complex of a CW complex $X_K$ . The complex $X_K$ is a (nonsimplicial) subdivision of the complex $X$ . The $(R,K)$ structure on $C(X_K)$ arises geometrically.

Profitability of Actors in the Value Chain of Commercial Rice

This qualitative study explored the value chain of commercial rice in Nueva Vizcaya, Philippines. It presented the value chain map of commercial rice highlighting the profitability of each actor involved in the value chain, namely paddy rice farmers, primary traders, millers, retailers, and final traders (wholesalers and retailers). The findings revealed that the miller contributes the highest value-added cost to commercial rice production, accounting for approximately 40.39% of the total, followed closely by the farmers at 39.22%. The primary trader represented 10.93%, while the wholesaler and retailer contributed 6.72% and 2.07% respectively. Analysis of the percentage of profit to cost showed that farmers earned the highest percentage at 32.36%, followed by the retailer at 8.48%, the primary trader at 5.11%, the miller at 2.32%, and the wholesaler at 1.68%. However, when considering the operating cycle of each actor, it became apparent that the primary trader emerged as the highest-earning actor due to their shorter operating cycle compared to other actors in the value chain. Hence, venturing into paddy rice production, trading, milling, and wholesaling of commercial rice in Nueva Vizcaya is profitable, given the wide market demand for rice as a staple food. There is a viable opportunity to enhance profitability among the various actors in the value chain, particularly for farmers, by leveraging appropriate government support programs, specifically by maximizing the utilization of initiatives provided under the Rice Tariffication Law.

A Study of Value Chain Map & Economics of Papaya in Karnataka State

The present study has attempted a detailed analysis of papaya fruit by studying its value chain map, establishment cost, cost and returns were important researchable issue for the said crop in kalaburagi district in Karnataka State. The findings reveal that, in value chain, farmers, pre-contactors, distributors, wholesalers and retailers will perform muti-task function in the system. Each of these stakeholders appends value during the movement of produce from one person to other in the consumption pattern system. The findings related to cost and returns, the year-wise analysis indicated that in the first year, the total cost for establishment was found to be Rs. 85225 in Papaya plantation followed by second year Rs.65432. The average of two years will be to the tune of Rs.65432 per acre. The per acre establishment cost accounted to Rs. 85225 of which the material cost constituted 78.37 percent to the total cost of establishment followed by human labour (19.64 per cent). The per acre cost of cultivation of Papaya was worked out to be Rs.65432, out of which the total variable cost share was Rs.45643 (69.75 percent) and total fixed cost was found to be Rs.19789 (30.25 per cent) to the total cost. total average cost for two years incurred in cultivation was found to be Rs.105328 and farmers obtain average net income of Rs.218247 per acre and the findings also revealed that the farmers the return on per rupee invested at total cost amounted to Rs.2.26 and 1.90 during first and second year respectively.
