Lurking Continents Beneath Antarctica

A new map reveals the remnants of ancient continents lurking beneath Antarctica’s ice.

The map shows that East Antarctica is made up of multiple cratons, which are the cores of continents that came before, according to study leader Jörg Ebbing, a geoscientist at Kiel University in Germany.

Losch Theory of Profit Maximisation

August Losch, a German economist, published his theory of ‘Profit Maximisation’ in the year 1954. The least cost location theory of Weber was wholly discarded by Losch. In fact, he suggested that, ‘profit maximization’ is the only objective of the entrepreneur, whether it is state or an individual. The major objective of the industry is, therefore, to find out the place where maximum profits occur.

Unlike Weber, who postulated his entire theory in an economic state of perfect competi­tion, Losch, on the other hand, explained his theory within the environment of monopolistic competition. According to Losch, industry will not necessarily be located within the least cost (transport cost and labour cost) location; rather it would locate in areas where maximum profit will occur. So, ignoring transport cost, labour cost and agglomeration cost, he emphasized more on the total production cost.

To get the maximum profit, as stated by Losch, total consumption is important. Higher the consumption rate, greater will be the profit. In this case, he emphasized most on the price reduction of the commodity. Any decrease in price would automatically stimulate the volume of consumption. This can be illustrated by the following diagram.

In this simple model, it is evident that when the price of the commodity drops from R to P, the consumption increases from M to N. The theory of August Losch considered demand as a most important variable. The funda­mental objective behind the theory was to find out the most profitable location for the industrial establishment.

To determine the location of maximum profit, Losch said, “The complexity stems from the fact that, there is more than one geographical point where the total demand of a surrounding district is at a maximum,………. We are thus reduced to determine separately for every one of a number of virtual factory location the total attainable demand, and for similar reasons the best volume of production as a function of factory price (Market and Cost analysis). The greatest profit attainable at each of these points can be determined from the cost and demand curves, and from this place of greatest money profits, the optimum location can be found”.

Losch argued that most of the existing theories are all simplified and generalizations of the complex problem of industrial location. Like Weber, he also considered certain assump­tions for the success of his theory.

Essay # Assumptions of the Profit Maximisation Theory:

Like Weber’s theory, ‘profit maximization’ theory of Losch is not universally applicable.

In the presence of certain optimum conditions the maximum profit location may occur:

1. The area under consideration should be an extensive homogenous plane where raw materials are distributed evenly.

2. The ‘transport cost’ is uniform and directly proportional in all the directions.

3. The people inhabiting the region have a general homogeneity either in taste, knowl­edge and technical skill.

4. There is no economic discriminations among the people. The economic and ca­reer building opportunities are open and uniform to all individuals.

5. The population distribution is very even and the area is self-sufficient in agricul­tural production.

In the case of excess production of agriculture, the status quo of the economy will be distorted. To achieve homogeneity of the economy within the region, the theory required some more condi­tions.

These are as follows:

1. The entire area should be equally served by the factories. No area should be ex­empted from the supply; therefore, no new firm would dare to venture in the area.

2. There must be conformity in the range and quantum of profit. In case of abnormal profit, new firms may try to establish their own plant.

3. The location must satisfy both producer and consumer. The profit of the firm and satisfaction of the consumer must be optimum through the location.

4. There must be provisions for consumers to get the products from other adjacent areas.

5. The number of consumers, producers and areas should be well defined and not very extensive. Only a limited number of producers within a small area will be able to overcome the complexities and satisfy completely the handful of consum­ers.

According to Losch, to get the desired result from the location and sustained growth of the industry, these conditions are pre-requisites.

Essay # Explanation to the Profit Maximisation Theory:

The major objective of the location theory is to attain equilibrium in the producing area and the product and the ability of the producer. If a single entrepreneur enters in the produc­tion process, within a vast area, the distribution cost will be very high.

But when several small producers are engaged in the production process in separate regions, the distribution cost will come down and due to increasing competition, efficiency of the product and cost of produc­tion will be lower.

The profit will increase substantially. Due to increasing competition, the area served by individual manufacturing units will be reduced. In the reduced area, several producing units will remain adjacent with each other, without leaving any area un-served. So, in this particular situation, a hexagonal area would serve the purpose. To establish his theoretical model of the theory, August Losch proposed three distinct phase of development.

The phases are as follows:

I. In this first phase Losch observed that if sufficient and symmetrical demand of a prod­uct prevails in the market, the market conditions may be explained by a demand cone. The following diagram illustrates that the effective demand of the particular product will be exactly same to the volume of the cone.

In Fig. 5, P is a producer, and demand curve is lying on QF. P or price line, controlled jointly by transport cost and distance. The price increased from P to F. Along the Y axis or PQ, demand of quantity is measured between PF and QF.

When PF is taken as a measure of distance and is rotated about P, the circular market area is formed, bounded by the locus of points F, where the price becomes too high. Total sales are given by the volume of the cone produced by the rotation of PQF.

In Fig. 5, it is clear that, away from centre, with increasing distance, demand of the quan­tity drops drastically.

II.In the second phase, within the vast rounded area, several factories will concentrate. The virgin, extensive market area will automatically give a lucrative operational area.. But despite the growing competition among the firms to capture larger share of consumer and larger market areas, there should be some void in the boundary zones.

Like intra-molecular space, a certain amount of region will remain un-served or poorly served. Though the mal­-distribution of firms may result in shrinkage of areas in some instances, some other regions will be devoid of any industry. The circular pattern of industrial hinterland in phase two will ultimately decide the future of the industry in that region.

In Fig. 6, the space situated outside the circular areas are still lying vacant. It is quite natural for the other industries to capture this potential market areas, hitherto unexploited. The influx of new industries in the region will result in shrinkage of the market areas (denoted in Fig. 6 by circle) of different production centres.

The intrusion of one market area to other will distort the circular market areas and the market areas of different production units will further reduce. This situation will lead to the initiation of the third phase.

Second Stage of Profit Maximization Theory

III.In the third phase of industrial location witness the narrowing of the intermediate space between two market areas. The areas fall vacant between the different market areas become the target of new enterprises.

As new firms set up within the vacuum, the hinterlands of earlier industries become reduced. The reduction of the market area results in rapid disrup­tion of the early circular pattern. Gradually the market area of the industries attain a hexago­nal shape.

According to Losch, when any area possesses several hexagons, lying upon each other and surrounding a particular centre, a metropolitan city will grow. In other words, it may be said that around the nucleus of a city, numerous hexagons or market areas of different com­modity will grow.

So, in this fashion, industries would concentrate within a region, each having different products. So, almost all types of materials including raw materials should be available on that point. Hence, any new industry would get its required raw material within near distance. Obviously, the total transport cost in that place will be minimum. In this way, ‘equilibrium conditions’ as stated by Losch may be attained (Fig. 6).

Losch, however, himself hinted about the deviation of his theory in some special condi­tions. According to his conception, when price of the commodity of a particular firm increases,demand of the product decreases considerably.

Naturally, due to higher price, the company loses some of its market area. Automatically, that area is encroached by the adjacent firm. In this fashion, market area of a unit changes continuously. This incident was explained by the figure given by Losch in Fig. 7.

Fig. 6 shows the development of hexagonal market area in the third stage. The dotted lines represent market boundaries of respective production centres. The crossed area is the production centre.

In Fig. 7, as stated by Losch, A and B are two producing centres, with total production cost of P and Q. Their respective market boundaries are CPD1 and EQD1. At the product cost of M, their production touches the optimum level and equilibrium is attained. But when production cost at A increase from P1 to P2, the equilibrium condition is dis­rupted. The product of A becomes less attractive than before, so market boundaries also re­duces from CP1D to C1P2D2.

Following the reduction of market of A, automatically market area of B advances in that void region. The previous area of EQD1 increases to EQD2. This D1D2 areal increase is well reflected in the circular diagram of Losch. The BD1 radius increases to BD2 and former AC radius reduces to AC1.

Essay # Merits of the Profit Maximisation Theory:

1. August Losch tried to restore a order in the former chaotic classifications of industrial location.

2. He was the first person to consider the influence of the magnitude of demand on indus­trial location.

3. August Losch rightly emphasizes upon the role of competition as an important determinant of location analysis.

4. The calculations adopted by Losch were simple and easily applicable to any place.

5. The theory has also a philosophical contribution on the motive of entrepreneurs’ role.

6. His equilibrium concept is perhaps the greatest contribution among the location theories developed later on.

7. The least cost concept of Weber was nullified by Losch and instead more precise ‘profit maximization’ concept was adopted.

Essay # Demerits of the Profit Maximisation Theory:

Of course, the theory of Losch was not entirely flawless. Numerous criticism from differ­ent quarters were put forward against the theory on various grounds.

The major points against the theory are as follows:

1. This theory is essentially a simplified model or theorizing of an ideal condition. In reality, only in a rare occasion, these events may occur.

2. The assumed conditions of homogeneous plain region, equal distribution of raw mate­rials and uniform transport rates never occur in the real world. Therefore, Losch’s theory, as said by some critics, is nothing but only intellectual exercise.

3. Losch even assumed the cultural homogeneity and uniform taste of the people within the region. This is nothing but absurdity.

4. He ignored the variation of technological development of different regions. The differ­ence of technical know-how may offset the theoretical model.

5. Political decisions play an important role in the industrial location. Losch ignored it.

6. The variation of the cost of raw materials and labour wage rates were not given proper weightage in the theory.

7. Losch categorically separated the role and effect of agriculture and industry. But this difference is somehow arbitrary in nature.

8. The abstract and optimum situation demanded by the theory may be available in agri­culture but not in the complex production process of modern manufacturing industries. Thus, Losch theory is more practical in agriculture, rather than in industry.

Future Cities: Fueling the Future by Mohd. Sadiq Khan

Future Cities: Fueling the Future

            Imagine a city of the future. Do you see clean streets, flying cars and robots doing all the work?

            “Or perhaps your vision is more dystopian”

Reality is no one really knows what the future holds, but we can predict and visualize, how our cities should be ….!!

Now almost 50% population lives in cities,

         By 2050  75% population live in cities (proj.)

The main challenge for today’s cities is to manage the heavy dependence on ecosystem services, which results in the depletion of natural resources and biodiversity and the efforts to mitigate and adapt to climate change, while prioritizing public health and quality of life.

How are Sustainable cities created :

         In the other words, to create a sustainable urban environment, it is crucial to measure and assess policies, infrastructure, socio-economic factors, resource use, emission and any other processes that contribute to and profit from the cities metabolism, prosperity, and quality of life.

Building the Smart City: Advancing Six fields

Future Economy :

         “Future Economy” describes all actions aimed at transforming and strengthening a municipality’s economy.

         Improving the overall business climate, a city’s attractiveness for start-ups, investors, businessman and new (highly qualified) talent as well as growing the economy in an innovative and sustainable way to increase competitiveness are the most important goals.

         There should be the utilization of technology and intelligent approaches lead to economy prosperity to generate favourable condition for all stakeholders.

         Government should invest to their young population, provide them better jobs, education etc. To provide opportunities and provide condition that supports the creation and growth of business as well as new jobs.

Future Government :

         Future government is about strengthening the connection and interaction between the government and citizens of the civil society – within a municipality.

         A municipal government following a smart city strategy is uniquely positioned to reconsider the quality, scale, and scope of service for citizens and businesses that it offers.

         By utilizing new methodologies, such as co-creation or crowdsourcing, or by implementing new technology and innovation a smart government can be developed.

         Following a ‘city as a service’ model can help to increase efficiency and effectiveness as well as transparency and trust.

Smart and Future Mobility :

         Future mobility focuses on increasing the efficiency and service quality of urban transportation to urban transportation to enhance the use and adoption of new mobility solution as well as to increase people mobility through efficient mobility management and targeted infrastructure investments.

         To achieve faster, cheaper and environmentally friendly mobility as well as integrated multimodal transportation is an important challenge for cities and communities.

         To support the combination of multiple modes of public and private transport and adopting new forms of transportation. Eg. The electric vehicle, hydrogen-powered vehicle, autonomous vehicle, bike sharing, car sharing is an important aspect for a future-oriented strategic approach to foster ‘Smart mobility’.

         Visitors needed to achieve a high-quality mobility service and to ultimately improve the flow of people and goods within a city or community, while at the same time reducing the environmental impact.

Future Environment :

         Future environment describes how a municipal people manages the built and natural environment to improve livability citizens and visitors.

         To utilize new technology and innovative methodology support the implementation of regulatory and cultural changes that facilitate sustainable standards and practice . The reduction of waste production, monitoring and managing pollution, emission reduction, water management, achieve energy efficiency and accelerating the local energy transition are some important goals.

         Vertical tree plantation in the new planned cities can curb the environmental threats.

Future Living :

         Future living aims at increasing quality of life for residents and visitors by following an inclusive strategic approach across all age groups and demographics.

         Smart living focuses on improving social and digital inclusion e.g. use of electronic services, connectivity, social platforms.

         Improving healthcare and care for the elderly e.g. health, ambient assisted living safety housing condition and smart buildings.

         New methodologies for civic and social engagement as well as new technologies e.g. lot based on wifi or LPWA network technology are leveraged to improve.

Future People

         Future people aims at transforming the way citizens interact via information or the provision of services with the public and private sector as individual or business.

         To create social and digital inclusion digital equality through educational offers is an important prerequisite for the more efficient provision of information and service based on new technologies.

         Second, the future people is about the smart form of education to facilitate career choices, labour market opportunities, vocational training as well as lifelong learning for all age groups and demographics.

         Talent development is also an important aspect from an economic development perspective as an increasingly important location factor.

         Future people solution supports the creation of an accessible and inclusive environment to increase prosperity and innovation with a city or community. Participation, open-mindness and creativity are some aspects that are enabled or nurtured by implementing intelligent solution.

Future City Projects :

Dolphin Watching: In Dublin, a scheme to monitor water quality in Gateway Bay by counting marine life has inspired an app for fisherman and restaurants to see what the catch of the day will be.

City Pulse: Silicon Valley firm scream point has developed a city dashboard which takes the pulse of the city from energy usage, to waste management.

Algorithmic Apartment: at MIT a team of engineers is working on homes with robo-walls that can be moved depending on need.

Re-Imaging the City by Maheen Naaz

            Thinking about the future is no easy task to accomplish, as we don’t know what is going to come up in the following years. However, there is a lot of interest in such question that what a future city will be like? We cannot even imagine our town in a decade from now ? can we?

            Re-imaging the city can be a provocation to reconsider and expand the range of possibilities for a city in the future. To make a city or a town better we have to keep in mind some important points for the future city.

Think about the possibilities

            We should think about the possible changes in the city which is likely to happen. By doing so we get useful ideas about our future city.

Imagine how to improve the life quality

            How we can make peoples lives more comfortable in the upcoming years. Several approaches to this progress such as the use of autonomous cars, the Internet of things or the development of the health care system.

Future Neighbourhood

            In a few years, every gadget will be connected to the internet, thus will interchange data automatically. How we can keep in touch with peoples in future in different other ways is yet to discover.

How will Our Future Cities Look?

            When we imagine a future city. Do we see clean streets, flying cars and robots doing all the work? Will we use flying cars to avoid the rush-hour in the cities of the future? Or perhaps our vision is more dystopian, with a Big Brother style authoritarian regime, dark alleys full of crime, peoples forced to line hermetically scaled pools because of war or some other disaster. No one really knows what the future holds, but the reality now is that our urban spaces are overcrowded and polluted. Almost half of the world population currently lines in cities and by 2050 that is projected to increase to 75%, but what kind of city will they be living in?

            In my opinion, if I would imagine the future of the city, it will be full of greenery, clean streets, smarter traffic systems, less crowded and more full of life.

Some important points related to the future city :

  • Greenification – sustainability experts predict carbon neutral cities full of electric vehicles and bike sharing schemes with air quality so much improved.
  • There should be an operation center which is described as ‘nerve center’ of the city to help deal with the floods, coordinates government agencies and provide mobile applications to keep citizens in touch with potential accidents, traffic black spots, and other city updates.
  • In a modern city, a digital system and digital infrastructure are essential to manage.
  • Shrinking Realm of Necessity – Imagine a city where there are limits on unnecessary things. Realm of necessity could be shrunk significantly without any significant negative impact on a desirable realm of freedom.
  • New cities needed to sustain an ever growing population, and retrofits on the ones that we have lived in for centuries.
  • Technology has more power to help people live in communities. For eg. Bejing, notorious for air pollution is testing an 23 fit tall air purifier that vacuum up smog, fitters the bad particles and releases a clean air which would help peoples of future city to survive in the harsh environment.
  • Infrastructure design and urban planning is another most important part of the future of the city.
  • Improving efficiency of the cities by eliminating redundancies, finding ways to save money and streamlining workers responsibilities which can provide higher quality services at lower cost.
  • To design an innovative citywide solid waste management system for the future city that is safe, environmentally sound and energy efficient.
  • Enhancing the quality of life which covers a broad range of issues including housing and transportation, happiness and optimism, educational services, environmental conditions, and community relationships.
  • There should be a community-dwelling center to accommodate poor, roofless, downtrodden to be run on a cooperative model.
  • Cities are different and their future are not the same. All in all, to some cities it may be finding ways to relieve polluter or congestion and for others it is more about findings ways to make cities greener. It is based on us that how we build our future city, “THE CHOICE IS OURS”.

“

“The Behaviour of a city is about the Behaviour of citizens.

Unless the system can become the fabric of their lives,

Nothing is going to change”.
