The empirical study of the price mechanism in the Chinese housing market

In China, the history of the establishment of the private housing market is pretty short. Actually in less then two decades, the market has grown from almost the scratch to playing an important role in the economy. A great achievement! But many problems also exist. They need to be properly addressed and solved. Price problem---simply put, housing price is too high--- is one of them, and this paper is focused on it. Three basic questions are posed, i.e. (1) how to judge the housing affordability? (2) why the housing price is so high? (3) how to solve the housing price problem. The paper pays particular attention to answering the second question. Except the numerous news reports and surveys show that most of the ordinary city dwellers complained about the high housing price, the mathematical means, the four ratios, are applied to judge the housing affordability in Shanghai and Shenzhen. The results are very clear that the price problem is severe. So why? Something is wrong with the price mechanism. This research shows that mainly these five factors contribute to the price problem: the housing reform, the housing development model, the unbalanced housing market, the housing project financing and the poor governmental management. Finally the paper puts forward five suggestions to solve the housing price problem in first-hand private Chinese housing market. They include: the establishment of real estate information system, the creation of specific price management department, the government price regulation, the property tax and the legalization of "cushion money".

A clear atomic example for the surface sensitivity of penning ionization

Using a crossed-beam apparatus with a double hemispherical electron spectrometer, we have studied the spectrum of electrons released in thermal energy ionizing collisions of metastable He^*(2^3S) atoms with ground state Yb(4f^14 6s^2 ^1S_0) atoms, thereby providing the first Penning electron spectrum of an atomic target with-4f-electrons. In contrast to the HeI (58.4nm) and NeI (73.6/74.4nm) photoelectron spectra of Yb, which show mainly 4f- and 6s-electron emission in about a 5:1 ratio, the He^*(2^3S) Penning electron spectrum is dominated by 6s-ionization, acoompnnied by some correlation- induced 6p-emission (8% Yb+( 4f^14 6p^2P) formation) and very little 4f-ionization (<_~ 2.5%). This astounding result is attributed to the electron exchange mechanism for He^*(2^3S) ionization and reflects the poor overlap of the target 4f-electron wavefunction with the 1s-hole of He^*(2^3S), as discussed on thc basis of Dirac-Fock wave functions for the Yb orbitals and through calculations of the partial ionization cross sections involving semiempirical complex potentiale. The presented case may be regarded as the elearest atomic example for the surface sensitivity of He^*(2^3S) Penning ionization observed so far.

The Pursuit of Alternatives

Stories of peoples’ struggles across the globe are testaments to their determination to resist exploitation and injustice, and to imagine and construct their own narratives of economic and political difference. These stories of emancipatory moments demonstrate that something radically different in terms of dominant socio-economic relations and mental conceptions of the world may arise out of and beyond capitalism. The Pursuit of Alternatives: Stories of Peoples’ Economic and Political Struggles Around the World presents a fresh and new perspective on how the ‘process of becoming’ alternatives might take place based on peoples’ lived experiences. The chapters here, by labour activists and academics, explore how various forms of peoples’ economic and political initiatives and struggles in six countries – Brazil, Canada, Colombia, Nigeria, the Philippines, and South Korea – might become ‘actually existing’ spaces and moments for the development of critical consciousness and transformative capacities which are both central in challenging the dominant social, economic and political relations. The stories in this book bring to light today’s language of peoples’ struggles; what inspires people to create their own emancipatory moments and spaces for transformative self-change. While this book does not aim to propose an alternative to capitalism per se, it makes a stimulating contribution to the continuing debate on what alternatives to capitalist relations and arrangements might look like by grounding these alternatives in the everyday lives and struggles of workers, women, aboriginal peoples, the unemployed, and the poor.

The Food Crisis: Implications for Labor

Food prices have gone up to prohibitive levels for many of the world’s poor. The vast majority of those who are hungry in the world today are working in agriculture, either as small landholders or as waged agricultural workers. The majority of the food producers have not benefited from rising prices. Apparently, the bargaining power of many producers, just as that of the end consumers, has been weakened vis-à-vis the buyers and retailers of agricultural produce. This powerlessness is also in the face of governments that fail to provide an appropriate infrastructure for smallholders and social protection. The first part of the book provides an introduction to the immediate and structural causes of the food crisis. The second part contains contributions that not only highlight the plight of rural labour but also develop tools for measuring the decent work deficit. The last part emphasizes income security as a major precondition for food security. It looks at the experiences of Brazil and India with the extension of social protection for the poor.

Employment and Income of Workers on Indonesian Oil Palm Plantations: Food Crisis at the Micro Level

The importance of oil palm sector for Indonesia is inevitable as the country currently serves as the world’s largest producer of crude palm oil. This paper focuses on the situation of workers on Indonesian oil palm plantations. It attempts to investigate whether the remarkable development of the sector is followed by employment opportunities and income generation for workers. This question is posed within the theoretical framework on the link between trade liberalisation and labour rights, particularly in a labour-intensive and low-skilled sector. Based on extensive field research in Riau, this paper confirms that despite the rapid development of the oil palm plantation sector in Indonesia, the situations of workers in the sector remain deplorable, particularly their employment status and income. This also attests that trade liberalisation in the sector adversely affects labour rights. The poor working conditions also have ramifications for food security at the micro level.

Poverty targeting and income impact of subsidised credit on accessed households in the Northern Mountainous Region of Vietnam

This paper uses the data of 1338 rural households in the Northern Mountainous Region of Vietnam to examine the extent to which subsidised credit targets the poor and its impacts. Principal Component Analysis and Propensity Score Matching were used to evaluate the depth of outreach and the income impact of credit. To address the problem of model uncertainty, the approach of Bayesian Model Average applied to the probit model was used. Results showed that subsidised credit successfully targeted the poor households with 24.10% and 69.20% of clients falling into the poorest group and the three bottom groups respectively. Moreover, those who received subsidised credit make up 83% of ethnic minority households. These results indicate that governmental subsidies are necessary to reach the poor and low income households, who need capital but are normally bypassed by commercial banks. Analyses also showed that ethnicity and age of household heads, number of helpers, savings, as well as how affected households are by shocks were all factors that further explained the probability at which subsidised credit has been assessed. Furthermore, recipients obtained a 2.61% higher total income and a 5.93% higher farm income compared to non-recipients. However, these small magnitudes of effects are statistically insignificant at a 5% level. Although the subsidised credit is insufficient to significantly improve the income of the poor households, it possibly prevents these households of becoming even poorer.

Segregation unter Stagnationsbedingungen

Anlass der Untersuchung sind Verstärkungen von strukturwandel- und globalisierungsbedingten Wandlungen unter Schrumpfungs- und Stagnationsbedingungen. Denn Stagnations- und Schrumpfungstendenzen in einer Region sind selektiv, sie begünstigen über verschiedene Mechanismen Polarisierungen und Marginalisierungen: Die allgemeine Entspannung am Wohnungsmarkt hat erhöhte Mobilität und damit sozialräumliche Segregierungen und Polarisierungen der Wohnungsversorgung zur Folge. Leerstände und ausbleibende Investitionen begünstigen Polarisierungen von baulich-räumlichen Qualitäten. Diese beiden Entwicklungen überlagern sich im Stadtraum und verstärken sich gegenseitig. Dabei verbessert sich die Wohnungsversorgung in den benachteiligten Quartieren kaum, so die Ausgangshypothesen. Die Untersuchung fragt nach den Wirkungen des Nebeneinanders von Wachstums-, Stagnations- und Schrumpfungserscheinungen auf unterschiedlichen Maßstabsebenen, dem Zusammenspiel von sozialstrukturellen und qualitativen Veränderungen der baulich-räumlichen Gegebenheiten in den Quartieren sowie in innerstädtischer Differenzierung. Dabei interessieren besonders die Einflüsse eines regional entspannten Wohnungsmarktes und dessen Folgen für die Verwertungsstrategien im Wohnungsbestand auf Segregationsprozesse und die Wohnungsversorgung. Als Fallbeispiel der Untersuchung dient die Stadt Kassel. Der sozialräumliche Fokus liegt auf drei Typen benachteiligter Quartiere: Neben den in der aktuellen Diskussion zumeist betrachteten gründerzeitlichen Arbeiterquartieren und den Großsiedlungen der 1960/70er Jahre wurden auch die peripheren Geschosswohnungsbausiedlungen der 1950er/60er Jahre in die Untersuchung einbezogen, um den unterschiedlichen Rahmenbedingungen und Wirkungen in den Quartierstypen auf die Spur zu kommen und damit letztlich Grundlagen für stadtentwicklungspolitische Strategien zu erarbeiten. Die kleinräumigen Analysen von sozialräumlicher und baulich-räumlicher Struktur sowie zur Wohnungsversorgung deckten Parallelen und gegenläufige Entwicklungen zwischen den unterschiedlichen Quartierstypen auf; es ergaben sich verschiedene Anhaltspunkte zur Erhärtung der Ausgangsthesen. So wurde z.B. deutlich, dass sich unter den Marktbedingungen stagnierender Städte die Wohnflächenversorgung in den benachteiligten Quartieren kaum verbessert. Hierin zeigt sich ein entscheidender Unterschied zu stark schrumpfenden Städten, in denen sich die Versorgungslage (fast) durchgängig verbessert. Wohnungsmarktbarrieren wirken offensichtlich unter Stagnationsbedingungen für bestimmte Bevölkerungsgruppen weiter. Da sich ihre Wirkung aber für weitere Kreise der Bevölkerung abschwächt, verschärfen sich sozialräumliche Konzentrationen. Vor allem aber wurden Überlagerung und gegenseitige Verstärkung dieser sozialräumlichen mit baulich-räumlichen Polarisierungen deutlich, die vor allem aus stadträumlich konzentrierten Investitionen in den Gebäude- und Wohnungsbestand resultieren. Letztlich zeigt sich damit, dass regulierende Eingriffe nicht nur im Rahmen des Umbaus und der Erneuerung der Quartiere erforderlich sind, sondern insbesondere auch in den Wohnungsmarkt und dies auch bei entspannter regionaler Marktlage. Andernfalls ist weder eine angemessene Wohnungsversorgung aller Bevölkerungsgruppen noch der Zusammenhalt der Stadt(Gesellschaft) zu gewährleisten. Dabei ist die Stadtpolitik permanent mit der Gleichzeitigkeit von (wirtschaftlicher) Standortpolitik und sozialer Stadtentwicklung konfrontiert, die sie im Sinne einer nachhaltigen Entwicklung gegeneinander und miteinander abwägen muss.

Förderung des Leseverständnisses durch Lesestrategien: Eine Interventionsstudie in der Grundschule

Anliegen dieser Dissertation ist die Untersuchung des Einflusses eines Lesestrategietrainings auf die Entwicklung des Leseverständnisses in den Klassen 2 und 4. In einer experimentellen Studie mit Prä-Post-Test-Design wurde die Wirksamkeit eines 25 Sitzungen umfassenden Trainings der Strategien Vorhersagen, kleinschrittiges Wiederholen und Zusammenfassen den Effekten einer lesefernen Kontrollbedingung gegenübergestellt. Die Lesestrategien wurden peergestützt vermittelt, d. h. in Dyaden aus einem leseschwächeren und einem lesestärkeren Kind. In drei Teilstudien wurden Fragestellungen zur differenzierten Analyse der Trainingswirksamkeit untersucht: (1) Wird die Trainingswirksamkeit durch die Effizienz der Worterkennungsprozesse beeinflusst?, (2) Kann die Entwicklung der Leseflüssigkeit durch das Lesestrategietraining gefördert werden? und (3) Können leseschwache Kinder von der Zusammenarbeit mit lesestärkeren Tutor(inn)en hinsichtlich der Verbesserung ihres Leseverständnisses profitieren?. Die Ergebnisse dieser Dissertation sprechen dafür, dass das eingesetzte peergestützte Lesestrategietraining das Leseverständnis und die Leseflüssigkeit von Zweit- und Viertklässler(inne)n unter bestimmten Voraussetzungen positiv beeinflussen konnte. Die Leseleistungen vor dem Training, die Effizienz der Worterkennungsprozesse und die Rolle im dyadischen Lernen erwiesen sich als relevante Einflussfaktoren für die Wirksamkeit des Strategietrainings. Zweitklässler(innen), die aufgrund guter Prä-Test Leseleistungen die Tutor(inn)enrolle erhielten, konnten ihr Leseverständnis gegenüber Kindern mit gleichen Leseleistungen in der Kontrollbedingung signifikant steigern. Leseschwache Zweitklässler(innen) hingegen schienen nur bei (relativ) effizienten Worterkennungsprozessen die Lesestrategien zur Steigerung ihres globalen Leseverständnisses nutzen zu können, wobei sie keinen Zugewinn aus der dyadischen Zusammenarbeit ziehen konnten. Bei ineffizienten Worterkennungsprozessen hatte das Strategietraining negative Auswirkungen auf das allgemeine Leseverständnis. Anders in Klasse 4: Kinder, die aufgrund unterdurchschnittlicher Leseleistungen im Prä-Test als Tutand(inn)en am Training teilnahmen, verbesserten ihr Leseverständnis und konnten dabei von der Zusammenarbeit mit lesestarken Tutor(inn)en profitieren. Für die Tutor(inn)en in Klasse 4 zeigte sich kein Effekt des Strategietrainings gegenüber der Kontrollgruppe. In beiden Klassenstufen stellte sich im Verlauf des Strategietrainings eine schnellere Entwicklung der Leseflüssigkeit der schwachen Leser(innen) ein. Zusammengefasst erzielte das Training die größten Effekte für gute Leser(innen) in Klasse 2 und schwache Leser(innen) in Klasse 4 – beide Gruppen konnten ihr Leseverständnis praktisch bedeutsam gegenüber Kindern mit gleichen Leseleistungen in der Kontrollbedingung steigern.

Opportunities and constraints of peri-urban buffalo and dairy cattle systems in Faisalabad, Punjab, Pakistan

In the big cities of Pakistan, peri-urban dairy production plays an important role for household income generation and the supply of milk and meat to the urban population. On the other hand, milk production in general, and peri-urban dairy production in particular, faces numerous problems that have been well known for decades. Peri-urban dairy producers have been especially neglected by politicians as well as non-government-organizations (NGOs). Against this background, a study in Pakistan’s third largest city, Faisalabad (Punjab Province), was carried out with the aims of gathering basic information, determining major constraints and identifying options for improvements of the peri-urban milk production systems. For data collection, 145 peri-urban households (HH) engaged in dairy production were interviewed face to face using a structured and pretested questionnaire with an interpreter. For analyses, HH were classified into three wealth groups according to their own perception. Thus, 38 HH were poor, 95 HH well off and 12 HH rich (26.2%, 65.5% and 8.3%, respectively). The richer the respondents perceived their HH, the more frequently they were actually in possession of high value HH assets like phones, bank accounts, motorbikes, tractors and cars. Although there was no difference between the wealth groups with respect to the number of HH members (about 10, range: 1 to 23), the educational level of the HH heads differed significantly: on average, heads of poor HH had followed education for 3 years, compared to 6 years for well off HH and 8 years for rich HH. About 40% of the poor and well off HH also had off-farm incomes, while the percentage was much higher - two thirds (67%) - for the rich HH. The majority of the HH were landless (62%); the rest (55 HH) possessed agricultural land from 0.1 to 10.1 ha (average 2.8 ha), where they were growing green fodder: maize, sorghum and pearl millet in summer; berseem, sugar cane and wheat were grown in winter. Dairy animals accounted for about 60% of the herds; the number of dairy animals per HH ranged from 2 to 50 buffaloes (Nili-Ravi breed) and from 0 to 20 cows (mostly crossbred, also Sahiwal). About 37% (n=54) of the HH did not keep cattle. About three quarters of the dairy animals were lactating. The majority of the people taking care of the animals were family workers; 17.3% were hired labourers (exclusively male), employed by 11 rich and 32 well off HH; none of the poor HH employed workers, but the percentages were 33.7% for the well off and 91.7% for the rich HH. The total number of workers increased significantly with increasing wealth (poor: 2.0; well off:2.5; rich: 3.4). Overall, 69 female labourers were recorded, making up 16.8% of employed workers and one fourth of the HH’s own labourers. Apparently, their only duty was to clean the animals´ living areas; only one of them was also watering and showering the animals. Poor HH relied more on female workers than the other two groups: 27.1% of the workers of poor HH were women, but only 14.8% and 6.8% of the labour force of well off and rich HH were female. Two thirds (70%) of the HH sold milk to dhodis (middlemen) and one third (35%) to neighbours; three HH (2%) did doorstep delivery and one HH (1%) had its own shop. The 91 HH keeping both species usually sold mixed milk (97%). Clients for mixed and pure buffalo milk were dhodis (78%, respectively 59%) and neighbours (28%, respectively 47%). The highest milk prices per liter (Pakistani Rupees, 100 PKR @ 0.8 Euro) were paid by alternative clients (44 PKR; 4 HH), followed by neighbours (40 PKR, 50 HH); dhodis paid lower prices (36 PKR, 99 HH). Prices for pure buffalo and mixed milk did not differ significantly. However, HH obtaining the maximum price from the respective clients for the respective type of milk got between 20% (mixed milk, alternative clients) and 68% (mixed milk, dhodi) more than HH fetching the minimum price. Some HH (19%) reported 7% higher prices for the current summer than the preceding winter. Amount of milk sold and distance from the HH to the city center did not influence milk prices. Respondents usually named problems that directly affected their income and that were directly and constantly visible to them, such as high costs, little space and fodder shortages. Other constraints that are only influencing their income indirectly, e.g. the relatively low genetic potential of their animals due to neglected breeding as well as the short- and long-term health problems correlated with imbalanced feeding and insufficient health care, were rarely named. The same accounts for problems accompanying improper dung management (storage, disposal, burning instead of recycling) for the environment and human health. Most of the named problems are linked to each other and should be addressed within the context of the entire system. Therefore, further research should focus on systematic investigations and improvement options, taking a holistic and interdisciplinary approach instead of only working in single fields. Concerted efforts of dairy farmers, researchers, NGOs and political decision makers are necessary to create an economic, ecological and social framework that allows dairy production to serve the entire society. For this, different improvement options should be tested in terms of their impact on environment and income of the farmers, as well as feasibility and sustainability in the peri-urban zones of Faisalabad.
