Hybrid MOOCS in Alliance University ..

Massive Open Online Courses (MOOCs) are the rage of the modern developed world to ensure lifelong learning and understanding of advanced concepts. Being taught by reputed Professors from reputed organisations across the world, MOOCs are being used both by students and employed professionals across the world to understand advanced and very modern concepts of knowledge to ensure lifelong learning. 

Being especially keen to ensure deployment of global standards of excellence and quality practices in Alliance University, around 2014-15, the Operations stream from AU first offered a hybrid course , integrating two MOOCs from with the core subject of Operations Strategy for MBA third semester students of Jan batch which I was engaging. One MOOC was offered before the midsem exams, MOOC on Competitive Strategy by Ludwig Maxmillens University, Germany and one after the midsem exams, Advanced Competitive Strategy, offered by the same University, (both were taught by Prof. Tobias Kretschmer). It was a success ! The exposure to the students was world class !! This was an augmentation for the students to classroom sessions and knowledge.

The hybrid learning experiment was continued in 2015-2016 for two more subjects.
We wish to share the learnings from this academic experiment with the faculty community of Alliance University. Prof. Sukanya Kundu from Operations stream of ASB has been going through many modern and latest MOOCs as a superior knowledge gathering and augmentation tool to help improve teaching and research effectiveness. As we know some more faculty from AU use MOOCs to augment their knowledge to ensure high quality academic delivery to students. This forum will help share our learnings and experience.

The Open Forum session this week looks at this knowledge sharing with the academic community of AU to help faculty across streams and Colleges to improve their teaching effectiveness and offer the best high quality learning experience to the students. Faculty members will be sharing from their personal experience. 
Date : 30 August 2018
Time : 3.30 - 4.30 PM
Venue : LHN 101
Topic of Discussion : Improving teaching effectiveness through MOOCs - live case study 
We shall be sharing a copies of a couple of draft papers from this experiment with the participants at the meeting. 
We request all teaching faculty looking to innovative ways to improve their learning effectiveness across the different schools of AU, across different streams of knowledge to participate in the discussion and help us to further the frontiers of knowledge.

Important documents on Disaster Management ..

The recent natural calamity of massive floods in Kerala of great magnitude caused by a mix of human induced and natural factors has caught the attention of people the world over. Understanding the causes of the floods to mitigate its negative impact and prevent recurrence of similar events in future is the only step forward. 

The exact timing of such stochastic events of great magnitude has always baffled scientists and researchers world over for centuries. One of the topmost ecologists of India and former Professor of environmental sciences at IISc Bangalore Prof. Madhav Gadgil (PhD, Harvard) had prepared a report on the man made degradation of the ecologically sensitive Western Ghats in Kerala and submitted to Government of Kerala in 2011. This sensitive report was outright rejected by the Kerala society due to their poor awareness of the possibility of destructive events of such enormous magnitude.

This massive degradation when combined with the destructive impact of overflowing massive water reservoirs used to generate electricity has a multiplier destructive impact on the environment and human settlements.

Here are a couple of docs of use for general reading and discussion to help get a good grasp of the event  and the regulations governing recovery and rehabilitation by the Government of India and NIMHANS Bangalore ..

Rainfall and floods in Kerala ..

This is the doc from IMD on Kerala rainfall . (click here - doc A)

My blog on Prof. Gadgil's writing ..(click here - doc B)

There are lot of comments coming out whether the Kerala govt could have done something earlier to prevent this disaster. A postmortem .. 

The learned Prof. Madhav Gadgil
Of all these analysis and learned reports, I feel Prof. Madhav Gadgil's report (doc B) and the watered down Kasturirangan report (under the pressure of the politicians and religious heads across Kerala) is the most important.

The Union Environment Minister Jairam Ramesh in February 2010 had a meeting in Kotagiri TN  with the representatives of the Save the Western Ghats which consisted of environmental experts from the Southern and Western states and wanted to asses the damages and recommend preventive measures which could prevent the degradation of the Western Ghats. Acordingly after the meeting Jairam Ramesh constituted the Western Ghats Ecology Expert Panel under Prof. Madhav Gadgil to assess the ecology and biodiversity of the Western Ghats which extends 1500 kms from Kerala right upto Gujarat and recommend measures to conserve, protect and rejuvenate the Western Ghats.

Findings of the Gadgil Committee report : 

The boundaries of the Western Ghats for the purposes of ecological management was defined. The total area in this boundary came to 1,29,037 square km, running about 1.490 km north to south, with a maximum width of 210 km in Tamil Nadu and minimum of 48 km in Maharashtra. It proposed that this entire area be designated as ecologically sensitive area (ESA). 

Within this area, smaller regions were to be identified as ecologically sensitive zones (ESZ) I, II or III based on their existing condition and nature of threat. It proposed to divide the area into about 2,200 grids, each approximately 9 km × 9 km, of which 75 per cent would fall under ESZ I or II or under already existing protected areas such as wildlife sanctuaries or natural parks.

It recommended:
  • Ban on cultivation of genetically modified plants in the entire area
  • Plastic bags to be phased out in three years
  • No new special economic zones or hill stations to be allowed
  • Ban on conversion of public lands to private lands, and on diversion of forest land for non-forest purposes in ESZ I and II
  • No new mining licences in ESZ I and II area
  • No new dams in ESZ I
  • No new thermal power plants or large scale wind power projects in ESZ I
  • No new polluting industries in ESZ I and ESZ II areas
  • No new railway lines or major roads in ESZ I and II areas
  • Strict regulation of tourism
  • Cumulative impact assessment for all new projects like dams, mines, tourism, housing
  • Phase-out of all chemical pesticides within five to eight years in ESZ I and ESZ II
The committee proposed a Western Ghats Ecology Authority to regulate these activities in the area.

Dr K Kasturirangan, courtesy Alchetron
When the recommendations of the Gadgil commitee was neglected by the government (to their own detriment ), it constituted another committee called the Western Ghats Expert Promotion Group under Dr K Kasturirangan (ISRO) in August 2012 which submitted its report in April 2013.

The Kasturirangan report broadened the definition of Western Ghats and included a total of 1,64,280 square km in it. 
  • Classified WG as comprising cultural landscape and natural landscape. 
  • Nearly 60% of the Western Ghats was cultural landscape, where human settlements, agriculture and plantations existed. 
  • The remaining was natural landscape, of which the “biologically rich” area was only 37% or about 60,000 sq km. 
  • It was only this part that the committee said needed to be classified as ecologically sensitive area (ESA)
Its main recommendations for ESA
  • Ban on mining, quarrying and sand mining
  • No new thermal power projects, but hydro power projects allowed with restrictions
  • Ban on new polluting industries
  • Building and construction projects up to 20,000 sq m was to be allowed but townships were to be banned
  • Forest diversion could be allowed with extra safeguards
In 2016, the Environment Ministry released the draft notification demarcating 56,285 sqkm of the Western Ghats as ESA from 59,940 sqkm as recommended by the KasturiRangan committee,,  ie, there has been further erosion from the KasturiRangan report too.

This is the latest status of the 3 environment committee report on the Western Ghats. While the first Gadgil committee report was very tough and insisted on strict measures for the preserrvation of the Western ghats ecological system in its pristine beauty and purity, the other two reports have been looking at widening the area under Western Ghats with a simultaneous dilution of the recommendations to preserve its purity and sanctity. 

All to the detriment not only of the people of Kerala but for the whole western coast of India.

Critical questions to assess the green building status ..

Some basic aspects of green buildings ..
As part of an assignment that I have given my students to assess the green building certification requirements and to record their observations on the same, I have prepared these set of questions.

A ‘green’ building is a building that, in its design, construction or operation, reduces or eliminates negative impacts, and can create positive impacts, on our climate and natural environment. Green buildings preserve precious natural resources and improve our quality of life.

There are a number of features which can make a building ‘green’. These include:
  • Efficient use of energy, water and other resources
  • Use of renewable energy, such as solar energy
  • Pollution and waste reduction measures, and the enabling of re-use and recycling
  • Good indoor environmental air quality
  • Use of materials that are non-toxic, ethical and sustainable
  • Consideration of the environment in design, construction and operation
  • Consideration of the quality of life of occupants in design, construction and operation
  • A design that enables adaptation to a changing environment - World Green Building Council 

How can we make our buildings green ? (click here ..)

A good set of questions to ask as part of the assignment ..

  1. Intent - Why have you gone for Green Building certification ?
  2. Initial preparations - What were the steps you took at the time of building the structure ?
  3. RM procurement - From where were raw materials procured ? Locally available ?
  4. Ventilation design for better air quality - How is the ventilation design of the building ?
  5. Optimal lighting system making use of natural lighting - What are the lighting systems used in the building ?
  6. Have you made use of natural lighting by giving enough windows, glass panels ?
  7. Green coverage - What percentage of your total area is built-up , ie. what is the greenery coverage ?
  8. Sewage water treatment plant - How is sewage water treated ?
  9. Collecting rain water - Is there rainwater harvesting in the building ?
  10. Electrc transportation  - Do you use any electric vehicles for transportation on the campus ?
  11. Advanced green technology augmentation  - Do you use any smart / AI system / IoT equipments to control usage of energy ?
  12. Air quality - What steps are taken to improve the interior air quality and environment in the rooms ?
  13. Solar energy / other renewable sources - have solar panels been deployed for electrical energy ?
  14. Energy use - are equipments having Energy Star ratings ?
  15. Painting - are walls painted with light colours enabling maximum reflection and less absorption ?

Thanksgiving as fishermen depart from water logged Kerala villages

Melancholy reigns - The local are really grateful ..
Near Chengannur, locals line the streets and salute the fishermen heroes as they pack their boats and leave. Salute to them! ❤

The locals have mixed feelings - of gratefulness, melancholy and sadness of separation of their loved ones from them, of deep grief and sadness .. The fishermen folk in all humility and feeling of sadness are in turn grateful to the public of Chengannur for giving them a chance to serve them and be of use to society.  

Really heart touching - no words to say how thankful they are  ..
The real heroes of the mission and the real patriots - the fishermen living in the coastal villages . Their selfless service helped save thousands of lives and rescue almost half of the million displaced people who are still in the camps .. The thanksgiving should not end here, this is just the beginning .. 

It is now the bounden duty of mainstream Kerala society to include these oft neglected sections of society in all our decisions on health, education, employment and infrastructure spending, they are more than our countrymen, they are our own dear beloved brethren and siblings !! 🙏🙏🙏🙏

The heavy price for Kerala on ignoring Prof. Gadgil’s advice ..

The Harvard educated Padma Bhushan former IISc Professor Madhav Gadgil, the environment scientist ..

If only the so-called Kerala intellectuals had heeded his advice .. 
He was called in by the social forestry department, by the then government of Kerala as part of the Western Ghats Ecology Expert Panel (WGEEP) to study the impact of deforestation in the Western Ghats: Illegal quarrying; illegal occupation of forest lands; sand mining from rivers and converting paddy fields to real estate.  

The WGEEP did submit its report in 2011. Prof. Gadgil cited all these and said Kerala, and districts from other states nearby, in the long run, will see devastation of unimaginable proportions.  Landslides will occur in every hilly region of the State and rivers will flood without any sand in their beds … and riversides will become a morass of illegal construction.

This gentleman professor gave a report over two thousand pages and urged the government to take action.  They did.  He had to leave in disgrace.  

The left parties and the right parties, in unison, called him names and conducted marches against him in all the hilly districts.  Nobody supported him.  No, not any one of us! So he left silently … and now, the most literate state in the Nation is gasping for survival.  It has been reduced to looking for help from every possible agency and even the Central Government.  

How many people have died and families rendered homeless! Politicians will survive; they always do, but shame on all us.  We have allowed ourselves to be betrayed by a nexus of arrogant politicians, advocates, builders and a corrupt administration.  Need anymore be said? (from the Internet ..)

We only have ourselves to blame ..

The watered down version of the WGEEP report (submitted in 2011) called the  "The Kasturi Rangan Report" was prepared in 2012 to placate the warring groups from the church and mainstream political parties, diluted the recommendations of the Gadgil committee report. The Gadgil Committee report was accepted by the UN and accordingly Western Ghats was declared part of the world heritage site.  The new diluted Kasturirangan committee (headed by former ISRO Chairman K Kasturirangan) to balance the concerns of ecological protection and development, instead of declaring 67% of the Western Ghats as Ecologically Sensitive area (ESA) zones as per Gadgil Report, brought it down to 37% ESA zones.

No amount of dilution to placate the public and the church will be tolerated by mother nature. What is happening in the state presently is very tragic .. Taking advantage of the piety of the average literate Keralite, both within and outside the state, religions and religious organisations are in top gear out to squeeze him even more to offer help to the suffering brethren, not taking a penny from their already overflowing resources. The churches inn Kerala are already overflowing with funds, still they want to squeeze the common man.  The government machinery in the flood affected areas has totally collapsed as the devastation is unimaginable ! 

Rains are pounding yet again across this small South Indian state of 33 million inhabitants and people  have to undergo great hardships .. The splurging culture of the average Malayali in extravagant spacious houses, cars and gold ornaments (one solid investment) has seen Kerala remain a place of unproductive investments. 

Even though the literacy rates are high in the state, there have been very low investments in job creating industries in the manufacturing and service sectors. The money order economy initiated by expatriates from the Gulf has started losing its charm of late, given the Arab urge to educate their citizens and promote their economic development. 

Trading, healthcare, education, real estate and cash crops like spices and of late the surge in IT companies opening up offer the only hope for the state in the present circumstances. Even though coupled with militant trade unionism, the socialistic experiment in Kerala has helped raise the standard of living and up the healthcare metrics, the average Malayali even to this day has to look outward of the state for gainful employment.

Makers of modern India - quiz

My small quiz - these great Indians are the makers of modern India .. can you identify them and their contribution ?

The real beauty of Idukki dam explained ..

The beauty of Idukki dam explained well .. 

Some musings on Idukki hydro electric project (IHEP) 
Chief Engineer( Retd),KSEB

Of late Idukki project especially 
Cheruthony dam with all the five radial crest gates partially opened and discharging up to 8 lakh litres per second has been stealing the thunder and the entire electronic and print media vying each other to beam the grand and rare spectacle across the world. Of course Cheruthony dam do deserve the publicity it is getting but as an engineer associated with all the three dams including its spillway gate operations , Idukki arch dam situated quite nearby should not feel alienated and let down by any means and I felt obliged to pen a few words .

It was early 1983 , a year or so after my my joining service at KSEB , I was posted at Idukki project in charge of the dam monitoring section. It was an obligatory posting after undergoing 5 months of intensive training at Montreal, Canada in Dam Monitoring & Instrumentation as part of the transfer of technology programme between Canada and India under CIDA (  Canadian International Development Agency) who aided the whole project.
The Idukki , Cheruthoni and Kulamavu dams forming part of the Idukki HEP were still in their infancy ( project was commissioned about 7 years back in late 1975) and constantly being monitored through the observation of the various parameters through the embedded instrumentation like electronic stress and strain gauges , base meters, suspended and inverted pendulums etc.

Idukki dam has several firsts to its credit. Simply speaking it is the first double curvature thin shell parabolic arch dam in India or in Asia. The Canadian consultancy firm M/s SNC who assisted in designing this unique structure had by that time completed the design and execution of a much bigger multiple arch dam  namely  Daniel Johnson across Manicougan river in Hudson bay , north of Quebec province in Canada and I am privileged to see that super dam ( 702 feet high with a volume 5 times of Idukki) considered to be the parent dam of our Idukki. 

Idukki dam's statistics are astounding and  features jaw dropping. It is almost 555 feet high from the deepest foundation ( It is hard to forget this figure as I had linked it to the famous cigarette brand State Express 555!) . 

Double curvature means it is built with curves in both vertical and horizontal axis. Thin shell denotes a portion of hen's egg shell known for its phenomenal strength.Eggs have a reputation for being quite strong under compressional loads. You won't believe your eyes when you see how strong they actually are — an egg can support a person!As compared to an egg shell having shell thickness of 0.6 mm , the Idukki dam bottom is more than 30,000 times thick at about 19 m and it tapers to about 6 m at the dam top. 

Shells structures derive their strength from curvature and so the geometry of the structure matters a lot.When the load applied is uniform/distributed, the forces experienced by the shell are transmitted as in-plane shear forces and the stress in the direction of thickness is negligible. Most importantly the principle of arch action (Instead of pushing straight down, the load of an arch  is carried outward along the curve of the arch to the supports at each end. The weight is transferred to the supports at either end. These supports, called the abutments, carry the load and keep the ends of the  spreading out) has been incorporated in the Idukki dam by the ingenious concept of an INVERTED ARCH. Here the huge thrust from the water is transmitted to the natural abutments viz. Kuravan and Kurathy Mala(hillocks) of igneous granite and charnockite formed millions of years back. 

The major advantage derived from Arch dam is minimal amount of concrete material required as the stresses of the thrust of water is taken care by both arch action and cantilever action requiring considerably small width at the bottom. Had Idukki been constructed  a conventional Gravity type dam , it would have consumed about 4 to 5  times as much concrete . With Idukki dam having 4.5lakh m^3 volume , one can calculate how much concrete has been saved by this clever design vis-a-vis Cheruthony gravity dam despite being  shorter  by 100 feet at 450 feet high having a volume of 17 lakh m^3.

As mentioned earlier my job was to monitor the performance of the dams due to the fluctuating water levels in the reservoir . Though these dams appear to be solid  monolithic impervious structures from outside , actually it is not so. In order to facilitate inspection a labyrinth of galleries have been provided in the core of the dam at different levels all connected through inclined galleries with steps . So also a maze of formed drains have also been provided through which whatever water seeping through the body of the dams are collected and safely let out . Lifts have been provided for gaining access to these galleries from dam top. While the lift machine room is visible for Cheruthony and travels through the dam body itself for Idukki due to the thin shell and parabolic arch section , the lift well has been provided inside the right abutment which is Kurathymala. It travels a vertical distance of almost 50 floors ( +500 feet) from gallery @ 1900 feet( all levels above Mean Sea Level in short MSL)  to dam top +2410 with two intermediate stoppage at +2100 & +2300 feet galleries) . That time it was one of the tallest lifts  (OTIS) in India which even now I am sure is true for our state . As the AE in charge It was part of my duty to maintain the trouble free operation of the lifts and a privilege to accompany VIP's and high ranking officials during their visit to the dams and for the travel in to galleries through the lift. 

I still recollect while descending with VIP's from top  suddenly  the lift got stuck about 250 feet( 25 floors )below, and I had to climb all the way up through the slippery rung ladder provided in the  vertical lift shaft with a free fall of about 50 stories so as to reach the machine room and meddle with some control relays to bring the lift up. That was one frightening experience and even now I get cold sweat recollecting it. 

Similarly my duties very often took me to the dam galleries which are dimly lit ,cold  eerily silent and lonely ( except the company of 2 or 3 staff to carry torch and small equipments for taking readings) environment and spent hours together. At times during such inspections power failure would happen and in such cases would have to climb the treacherous steps to the exit with the faint  glow of a torch  in pitch dark. Mind that hardly few meters away huge reservoir with 2 Thousand Million Cubic meter (2000TMC) of water is  
thrusting against the dam body. But we had absolute faith that the dam will not cheat . And for the next five years or so the galleries of  Idukki , Cheruthoni and Kulamavu dams were practically like a second home for me. Such intimate was my association , I believe even now the dams may perhaps remember me  if I go near it!

Last week  the spillways of Cheruthoni were opened with a maximum regulated discharge of 8 lakh litres per second. At least few people had a doubt what would happen if more inflow to the reservoir had occurred demanding higher spillage. To that query , Cheruthoni spillways can handle even 5 times that ( 42.5lakhs/ sec)spill , but pray that nature will not test us to such extreme level. 

To sum up I can confidently state that the  KSEB dams are built to last and they will withstand the vagaries of nature and act as our guardian Angeles for a long time to come from deluge.

Doing role play in the classroom ..

How to Use Role Play

Frequently we come across situations where students are unfamiliar with the case and cannot figure out what's happening. In such situations it helps to do a role play assigning different students to different characters in the case. This helps the students to understand in real time the mindset of the character, the difficult decision making he /she has to do, the many data he /she has to gather and process . It is as effective as a case study less the actual field data ..

It is easy to set up and run a role-playing session. It will help to follow the five steps below.
Step 1: Identify the Situation 
To start the process, gather people together, introduce the problem, and encourage an open discussion to uncover all of the relevant issues. This will help people to start thinking about the problem before the role-play begins. 
Step 2: Add Details 
Next, set up a scenario in enough detail for it to feel "real." Make sure that everyone is clear about the problem that you're trying to work through, and that they know what you want to achieve by the end of the session 
Step 3: Assign Roles 
Once you've set the scene, identify the various fictional characters involved in the scenario. Some of these may be people who have to deal with the situation when it actually happens (for example, salespeople). Others will represent people who are supportive or hostile, depending on the scenario (for example, an angry client).
Once you've identified these roles, allocate them to the people involved in your exercise; they should use their imagination to put themselves inside the minds of the people that they're representing. This involves trying to understand their perspectives, goals, motivations, and feelings when they enter the situation. 
Step 4: Act Out the Scenario 
Each person can then assume their role, and act out the situation, trying different approaches where necessary. It can be useful if the scenarios build up in intensity. For instance, if the aim of your role-play is to practice a sales meeting, the person playing the role of the potential client could start as an ideal client, and, through a series of scenarios, could become increasingly hostile and difficult. You could then test and practice different approaches for handling situations, so that you can give participants experience in handling them. 
Step 5: Discuss What You Have Learned 
When you finish the role-play, discuss what you've learned, so that you or the people involved can learn from the experience

Results of the game played in the BBA sem 5 Operations class ..

By playing this game it becomes easy to understand the role played by the important stakeholders in taking the decision and solving the management problem. For examples, we did a role play of the


The stakeholders who were taking part in the role play were

  • a very concerned citizen
  • the Chief Minister of the State
  • the BBMP Commissioner representing the Bangalore corporation body
  • the Director General of Police (DGP) representing the Police and law enforcement, 
  • the representatives of the two and three wheeler and light 4 wheeler owners and 
  • the representative of the heavy multi tyre and OTR vehicles. 

The rest of the students in the class were again part of the audience.

In about an hour, the students got a grip of how the role play is enacted and brought out various dimensions and perspectives of the problem like

  • metro construction
  • most of the IT employees not taking car pooling seriously
  • no proper segregation of lanes for buses and private vehicles
  • unrestricted movement of heavy trucks and cargo vehicles blocking other vehicles movement
  • not enough width for roads
  • proposing fines on single occupant vehicles
  • providing safety  for ladies in share cabs and so on.

Understanding the disposal habits of people ..

While trying to research into what influences people's behaviour to disposal, I found that understanding the disposal habits of people is important to find what they dispose and what they do not.  

There are three aspects which influence our disposal habits

1. Distortion bias - Through experiments it was found that people tend to less dispose of end products which have been crushed or distorted than end products which have not been distorted. Only good form end products make it to recycling than crushed or distorted end products.

2. Identity bias - end products with either name or photo of the user tends to get recycled more than items which do not have identification details of the user. 

3. Knowledge of recycling -  How much of resources we use and how much we waste depend to a great extent to the knowledge on how the resource can be recycled. If we know that the end product is going to be recycled, it is but human tendency that we use more of the raw material than if we were to know that the end product would not be recycled. We see here that positive emotions associated with recycling can overpower the negative emotions associated with wasting of resources.

What finally is the awareness of this knowledge what influences disposal behaviour ?

Companies can plan to have end products which are difficult to damage so that it will find its way to recycling than to waste heaps.
