Majority and minority group in kosovo |
|
Answer» Explanation:Main languages: Albanian, Serbian, also Turkish, Romani, Bosnian. Main religions: Islam, Orthodox Christianity, also Roman Catholicism Minority and indigenous communities: According to the 2011 census (excluding North Kosovo) the main minority groups are Bosniaks (1.6 per cent), Serbs (1.5 per cent), Turkish (1.1 per cent), Askhali (0.9 per cent), Egyptian (0.7 per cent), Gorani (0.6 per cent), and Roma (0.5 per cent). However, because North Kosovo was excluded from the census, the true proportion of some minorities – particularly Serbs, who in some areas of the north comprise the majority of the population – may be under-estimated in these figures. It should be noted that in Kosovo minority groups have often been referred to as ‘communities’, defined in the new Kosovo Constitution as ‘inhabitants belonging to the same national or ethnic, linguistic or religious group traditionally present on the territory of Kosovo’. This terminology is used as the term ‘minority’ is shunned, particularly by Serbs, many of whom see Kosovo as part of Serbia and accordingly do not believe they are a minority. Kosovo has a population of approximately two million. Ethnic Albanians form the overall majority with 92.9 per cent. Most Albanians are Muslim and speak Albanian. The last census in Kosovo took place in 2011, excluding North Kosovo. The Serbs, the largest minority group in Kosovo, speak Serbian and are predominantly Orthodox Christians. The 2011 census left out the Serbs in North Kosovo where many of them reside. According to estimates based on 2010 and 2013 OSCE data, there were 146,128 Serbs living in Kosovo, making up 7.8 per cent of the total population, a much larger proportion than the 1.5 per cent estimate in the 2011 census: of these, 70,430 were in northern Kosovo and 75,698 in southern Kosovo, with a total of 10 municipalities where Serbs are a majority. Smaller communities include Roma, Ashkalia, Egyptians, Bosniaks, Turks, and Gorani. Within Serb compact SETTLEMENTS, Albanians are effectively a minority. Important demographic changes took place during the 1998-1999 war and subsequent ethnic violence. Exercising the right to self-identification is DIFFICULT in Kosovo, mainly because people are afraid to openly state their ethnicity for FEAR of discrimination, but also because others do not necessarily respect people’s identity, for example international and local actors often grouping Roma, Ashkalia and Egyptians into one. The size of the Serbian population has DROPPED dramatically since the end of the war in 1999 and notably in the wake of the Kosovo’s declaration of independence in February 2008. Most Ashkalia (estimated at 15,436 in the 2011 census, excluding North Kosovo) speak Albanian as their first language and practice Islam. Until the 1990s most Ashkalia identified themselves as Roma, when they began to identify themselves as a distinct group. However, they have not been accepted by the Albanian community: they face widespread discrimination and exclusion from economic life. Although the Ashkalia have one reserved seat in the Kosovo Assembly, they have been excluded from MEANINGFUL participation in political life. A similar situation is experienced by Kosovo’s Egyptians (numbering 11,524 in the 2011 census, excluding North Kosovo). They also speak Albanian as their first language and practice Islam. Identifying as Roma until the 1990s, they now trace their origins back to Egypt and identify themselves as a distinct group. Like the Ashkalia, they suffer widespread social exclusion and economic marginalization. Although the Egyptians have one reserved seat in the Kosovo Assembly, they too have been excluded from any real participation in political life. |

Difference between history and economics?( atleast 4 points). |
|
Answer» social sciences, each field is filled with ill-defined concepts and terminology that is INCONSISTENTLY USED and leads toward DIFFERENT starting positions. In short, In many publications you will FIND different definitions, while 'new' is a very tricky word. Think of 'new media' 'or new technologies'.Economic history is, I think, easy to define, since it refers to a SYSTEMATIC, study of economic phenomena in the past. Since it is a scientific endeavor, it uses several methods to warrant objectivity, validity, and reliability.New economy, however, reflects different meanings,depending on the angle.New economy, from an more humanistic approach, refers to the predominance of human values and sustainability instead of mere economic growth. lf the approach is oriented toward production then shift from a manufactory-based toward a service-driven economy is used. And, if te term is used to make distinction in the scientific approach, new economic history refers to more formal or mathematical research methodologies. Explanation: |

Essay on problems faced by india and how youth can solve them |
|
Answer» mately 600 million population in India is younger than 25 years of age and close to 70% of the total population is less than 40 years of age. Near about 40% of the Indian population is aged between 13 to 35 years that is defined as youth according to the National Youth Policy. Such a huge population of young is not only exceptional in India but also in the World. In case, this demographic dividend is not used properly then it may result in demographic disaster in India. The youth then will not be on right track. Also if we LOOK at the median age of the country and the average age of our leaders then it is clear that country’s median age is 25 years whereas the average age of our cabinet ministers is 65 years. Hence there EXISTS a gap in age which leads to a gap between thoughts. This gap in India is much wider than the gap in any other country, such as in United States the gap is of 23 years whereas in Germany the gap is less than 10 years. History reveals that in such a scenario where there exists such a wide gap and most of the population is comprised of youth then it definitely leads to one or more political movements in the country. This had been seen in America at the time of the civil rights movement and the sexual revolution which happened during America’s baby boomers period when 79 million people born between 1946 and 1964. Even if you check the history of India then also it is clear that youth can bring a huge change. Almost all our freedom fighters were young when they started their struggle for freedom that resulted in the freedom of our country. But this enthusiasm among today’s youth is eloping somewhere leading to frustration and lack of zeal. The reason may be unnecessary burden in the FORM of competition, unemployment, lack of job skills and skill based job etc. Indian Youth at present is also facing acute pressure in every field from getting job to performance at the job. In the coming decade, it is expected that the Indian labour force will grow by more than 8 million per annum. More and more youth will enter into the labor market. So the real CHALLENGE in front of the policy makers is to create enough JOBS in the market for this educated workforce so as to direct the youth and nationsome key problems are education,job and corruption |

IS THE INDIAN MEDIA POLITICALLY MOTIVATED INSTEAD OF PLAYING AN INDEPENDENT ROLE.. 150-200 WORDS |
|
Answer» No, I don't THINK so as the media is an independent body in itself only which does not NEED any kind of motivation and will not stand any kind of pressure. In TODAY's time the media is so powerful that it can influence almost anybody. Instead, we are the ones who easily come in media's statements and believe them without question. At last, media is capable of being independent and is not at all motivated by political PEOPLE because if it did, the people will not get any REAL information.hope it helps.... |

B) Avenues and tools of communication |
|
Answer» 1. In-person interactionsThis one is generally the most APPLICABLE to customers going to a physical shop, but is also beneficial for entrepreneurs that work from home. (After all, you’ll still need to meet with potential partners or other outside individuals at some point!)In-person interactions require you to pay attention to the BODY language and social cues of the customer as well as yourself. Be friendly, smile, look people directly in the eye, and have an understanding of their personal space. Make yourself available and present to answer any questions that the customer may have, but also allow them some room to browse and look around. They may not make a purchase TODAY, but that doesn’t mean that they won’t return at a later date to shop with your business.2. Phone callsPhone calls are still one of the most reliable forms of customer service support. They allow you to address any issues that the customer may be having and walk customers through situations where they might need a bit of guidance, such as navigating a website. At the end of the call, you may even ask the customer to take a brief survey. This will let you know if they were satisfied with their call experience. If not, they can make suggestions for what you may be able to do better next time.3. EmailsOne of the best parts of emailing back and forth with a customer is that you are able to follow-up once the exchange is complete. Through your email correspondence, you have been able to ESTABLISH a rapport with the customer and get to know them on a first name basis. After the issue has been resolved or questions have been answered, you can follow-up later to see how they’re doing and offer assistance tailored specifically to that customer.4. Engaging through social media platformsDoes your business have a presence on sites like Facebook, Twitter, or Instagram? If so, this is the perfect place to connect with customers that have questions and help answer them in real time. You can follow some of your brand’s most loyal customers, create CONTENT that allows them to engage with your brand, and share news about new product or service launches. |

किरणोत्सारी पदार्थ म्हणजे काय |
| Answer» EXPLANATION:काही विशिष्ट मूलद्रव्यांच्या अणुगर्भांच्या (अणुकेंद्रांच्या) अस्थिरतेमुळे स्वयंप्रेरित विघटन (फुटण्याची क्रिया) होते आणि त्यामुळे काही किरणांचे वा कणांचे उत्सर्जन होते, या आविष्काराला किरणोत्सर्ग म्हणतात. रॉंटगेन यांच्या क्ष-किरणांच्या शोधानंतर (१८९५) थोड्याच महिन्यांत १८९६ मध्ये आंत्वान आंरी बेक्रेल यांना किरणोत्सर्गाचा शोध आकस्मिकपणे लागला. अनुस्फुरण (एखाद्या पदार्थाने एखाद्या विशिष्ट तरंगलांबीच्या प्रारणाचे म्हणजे तरंगरूपी ऊर्जेचे शोषण करून जास्त तरंगलांबीच्या प्रारणाचे उत्सर्जन करणे) या आविष्काराबद्दल संशोधन करीत असताना बंद पाकिटात ठेवलेल्या छायाचित्रण काचा व बोहीमियामधील पिचब्लेंड या युरेनियम ऑक्साइडयुक्त खनिजाचा संबंध आला होता; या काचा धुतल्या असता त्या काळ्या झालेल्या बेक्रेल यांना आढळून आल्या, साहजिकच या पिचब्लेंडमध्ये असलेल्या युरेनियमच्या पारगामी (आरपार जाणाऱ्या) किरणांमुळे असे झाले असले पाहिजे असा बेक्रेल यांनी तर्क केला व या प्रकारास त्यांनी किरणोत्सर्ग हे नाव दिले. सुरुवातीच्या संशोधनावरून या किरणोत्सर्गाचे मूळ अणुगर्भाशी निगडित असून या आविष्कारावर रासायनिक विक्रियांचा तसेच भौतिकीय परिस्थितीचा काहीही परिणाम होत नाही असे आढळले.सॉरबॉन येथील विद्यार्थी प्येअर क्यूरी व मारी क्यूरी यांनी किरणोत्सर्गाचे कारण शोधून काढण्याचे काम अंगावर घेतेले व त्याचे पर्यवसान म्हणून प्रथम पोलोनियम आणि नंतर रेडियम या किरणोत्सर्गी मूलद्रव्यांचा शोध लागला.किरणोत्सर्गाच्या क्रियेमध्ये अणुगर्भाचे विघटन होऊन त्याचे दुसऱ्या प्रकारच्या अणुगर्भात रूपांतर होत असते असे रदरफर्ड आणि सॉडी या शास्त्रज्ञांनी दाखवून दिले. अणूचे अस्थैर्य हे किरणोत्सर्गाचे कारण असते आणि असे अस्थिर अणू निसर्गात सर्वसाधारणपणे अणुक्रमांक (अणुगर्भातील प्रोटॉनांची संख्या) ८२ ते ९२ पर्यंत आढळतात. रदरफर्ड यांचा दुसरा शोध म्हणजे अणुगर्भाचा. अणूचा प्रकार आणि त्याचे रासायनिक गुण हे अणुगर्भावरच अवलंबून असतात. रदरफर्ड यांचा तिसरा एतद्विषयक शोध म्हणजे उत्सर्जित किरण तीन प्रकारचे असतात हो होय. हे तीन प्रकार म्हणजे (१) आल्फा (α) किरण : हे हीलियम या मूलद्रव्याचे अणुगर्भ होत, (२) बीटा (β) किरण : हे इलेक्ट्रॉनच होत आणि (३) गॅमा (γ) किरण : म्हणजे विद्युत् चुंबकीय प्रारणाचे पुंज (विभाजन करता येत नाही अशी किमान राशी, क्वांटम) होत. १९१९ मध्ये कमी अणुक्रमांकाच्या अणुगर्भावर α कणांनी आघात केल्यास त्याचे विघटन होऊन रूपांतरण (एका मूलद्रव्यापासून दुसरे मूलद्रव्य तयार होणे) होते आणि त्यातून प्रोटॉन (P) बाहेर पडतात असे रदरफर्ड यांनी सिद्ध केले. या पहिल्या कृत्रिमविघटन क्रिया होत. १९३४ मध्ये ईरेन झॉल्यो-क्यूरी आणि जे. एफ्. झॉल्यो या दांपत्याने ॲल्युमिनियमावर α कणांचा आघात करून त्यातून पॉझिट्रॉन(इलेक्ट्रॉनाइतकेच द्रव्यमान व विद्युत् भार असलेले पण विद्युत् भार धन असलेले मूलकण) बाहेर पडतात असा शोध लावला. विघटित केंद्रांचे रूपांतर किरणोत्सर्गी फॉस्फरसामध्ये होते व या फॉस्फरसाच्या अणुगर्भातून पॉझिट्रॉन उत्सर्जित होतात असे दिसून आले. या घटनेला त्यांनी प्रवर्तित किरणोत्सर्ग असे नाव दिले. | |
