The Onset of Health Problems and the Propensity of Workers to Change Employers and Occupations

Although many studies have investigated how poor health affects hours of work and labor force participation, few have examined the extent to which individuals adapt in order to remain in the labor market. Individuals experiencing health problems may move to different types of work in order to remain in the labor force or to reduce the negative labor market consequences of illness. This paper investigates the movement between employers, and among occupation categories when changing employers, using data from the Health and Retirement Study (HRS). One advantage of the HRS is that its questions on life‐cycle employment and health patterns permit a long‐term perspective on job mobility that is unavailable in most other datasets. Workers with health problems are more likely than healthy workers to remain with their current employer than to switch employers. But among those who switch employers, those with health problems are more likely to change broad occupational categories than are healthy workers. While many individuals remain with the same employer after the onset of health problems, many do switch employers and occupations, even in the presence of ADA legislation.     

Return migration,rural household investment decision,and poverty alleviation: Evidence from rural Guangdong,China

Return migration has been considered advantageous to the productivity of labor and the economic development of origin regions and countries. However, how and why return migrants make their investment decisions and how such processes contribute to poverty alleviation remains unclear. This study evaluated how migration experience influences rural families' choices for productive investments and the underlying mechanism of village poverty alleviation. The result indicates that, when all are given the same monetary budgets, return migrants are more inclined to invest in single agricultural-related subjects rather than multiple subjects. A concentrated investment implies the investor's intention of expanding the production scale, which can further lead to a more organized, professional agricultural production that can be considered beneficial for community poverty alleviation. Moreover, different approaches of human capital accumulation led to varied capacity growth, among which migration experience effectively enhances the non-cognitive ability of return migrants. Based on these findings, we suggest that more returnee-preferential policies, supporting production and organization services should be established to promote agricultural entrepreneurship among the returning groups in poor rural areas.     

Elephants in the Pacific? Pacific urbanisation and its discontents

Urbanisation has proved seemingly inexorable in the island Pacific in recent decades, yet has largely escaped critical attention. Urban growth has been associated with civil unrest, unemployment, crime, poverty, environmental degradation, traffic congestion (and heightened inequality), inadequate formal housing provision, the rise of the informal sector (and repressions of it), pressures on education, housing, health and other services such as water and garbage disposal, rather than with sustained economic growth. Such wide‐ranging issues have posed problems where economic growth is static, structures of urban governance are lacking or weak (or corrupt), land disputes are frequent and urban populations increasingly permanent. Urban development necessitates balanced regional development and sustainable urbanisation or the future will lie elsewhere.

ASEAN Forum on Migrant Labour: A space for civil society in migration governance at the regional level?

The aim of this article is to discuss and substantiate new spaces for the political participation of migrant civil society at the regional level in Southeast Asia through the lens of the Association of Southeast Asian Nations (ASEAN) Forum on Migrant Labour (AFML). The AFML process is shaped by the International Labour Organisation and mirrors its tripartite format, essentially bringing together governments, employers’ and workers’ organisations. Crucially, migrant support and self‐organisations also have access, even if somewhat restricted, to regularly held deliberations. In light of the ASEAN consensus on migration that was agreed upon at the end of 2017, the article situates the AFML within the ongoing process of migration governance in the region and focusses especially on the role of migrant civil society as an important stakeholder. Based on the specific experience of civil society organisations (CSOs) from Malaysia, the article discusses which spaces the forum provides for civil society actors and how the latter use them for their advocacy. The major argument of the article is that the development of migration policies at the regional level can benefit from the inclusion of migrant civil society in the process. The governance of migrants could thus be complemented by governance for and by migrants.

Grey Optimal Options of Design Plans for Deep Cutting Slope

The selection of the design plans for deep cutting slope of high-level highway in mountain area,in general speaking,only depends on the designer's experience and intuitive determination at the present time,which results in unreasonable,even error,decision or plan.It unavoidably causes enormous damage.This paper proposes to adopt correlation degree analysis method of grey system theory for choosing the optimal design plan.It will give a definite and real meaning about choosing design plan and avoiding or reducing errors in design work.     

Use of a Disk Meter to Evaluate Continuously Grazed Pastures

One of the greatest difficulties in pasture research is accurately measuring quality and quantity of the vegetation. The disk meter may be used to rapidly estimate herbage mass (DM) but its validity depends on a good relationship between disk meter height (DMH) and DM. The objective of this study was to determine the relationship between DMH and DM for continuously grazed pastures. Pastures of varied botanical composition were grazed by cows and calves from May through October. Paired data (DMH and DM clipped from under the disk) from seven cool season pastures were subjected to covariance analysis. Prediction equations were developed utilizing data from 2 years for different pastures and dates. Disk meter height accounted for a little over half the variability in DM (R² of 0.54 and 0.59 for years 1 and 2, respectively). Regression coefficients of DM on DMH differed between dates in both years and between pastures in one year. To accurately predict DM the disk meter must be calibrated for each pasture and date. However, the disk meter can be used where an estimate of herbage mass is required and resources are limiting.

Rule of law,anti‐corruption,anti‐terrorism and militant Islam: Coping with threats to democratic pluralism and national unity in Indonesia

Abstract: President Yudhoyono, Indonesia's first directly elected president, was swept into office on a wave of popular support, but was faced with a formidable array of challenges, each demanding a prompt and effective response. Among the most immediately pressing, calling for crisis management, were: first, the need to assert political control and to build an effective political coalition; second, the need to secure grass‐roots democracy by ensuring that regional elections were effectively carried out; third, the need to cope with the Aceh tsunami crisis and achieve a peaceful reconciliation with the Free Aceh Movement; and fourth, the need to resolve a series of socioeconomic policy ‘growth versus equity’ dilemmas, to attract foreign investors to stimulate export‐led growth, while securing basic needs and anti‐poverty social programmes. After briefly noting how Yudhoyono and his administration responded to these immediate problems during its first 20 months in office (to June 2006), the paper then discusses at greater length three more fundamental and intractable sets of problems, namely, the urgent need to implement judicial and administrative reform, and to launch a wide‐ranging anti‐corruption campaign; the need to confront the resurgence of militant Islamic terrorism, both inter‐communal and al‐Qaeda‐inspired, and to mount a robust anti‐terrorist campaign; and finally the intense and convoluted problem of inter‐sectarian animosities, and the clash of religious versus secular values, the reconciliation of which will be absolutely critical to securing social stability, democratic pluralism, national unity and Indonesia's futurity.     

The method of dynamic aperture control technology based on ultrasound imaging system

Dynamic aperture control technology is one of the most important parts in ultrasonic imaging system. Excellent control technology of dynamic aperture can effectively improve the quality of ultrasonic imaging. Based on deep analysis of ultrasonic beam distribution, a control method for dynamic aperture which can eliminate the scanning dead zone of focused beam is presented. The detection region is even divided according to the number of probe array elements. The desired focused beam width is calculated between the next two scan lines at different depths, and then according to the beam width, the required aperture size for different depths is determined. The method is not affected by the probe parameters or detection objects, and it can be widely employed in ultrasonic imaging system. The simulation experiments indicate that the proposed method can effectively improve the whole quality of ultrasonic imaging.     

Analysis on Correlated Problem with Control of Uncertainty System

The majority difficulty for uncertainty system control is that agreements haven't been arrived in concept of uncertainty information and its characteristics, uncertainty system and its properties. Therefore some control problems have discussed based on some confused concepts, and the result shows that the study on uncertainty system control hasn't made great progress yet. In addition, problems concerning uncertainty system control are very wide in the practical engineering. Aimed at above problems the concept of uncertainty information and its classification, basic properties of uncertainty system and desired control strategy based on own practical experience are studied. Finally, that intelligent control strategy is wise choice for uncertainty system control based on successful engineering application.     

THE INTERMEDIATE SKY IS COMPOSED OF THE PSEUDO-CLEAR SKY AND THE PSEUDO-OVERCAST SKY

This paper suggests that the actual sky,with the exception of a few par-ticular weather conditions,such as rain and snowstorm in which artificial lighting is needed.The sky can bc divided into four types according to their sunlight conditions and sky luminance distrbutions,they arc clear sky,pscudc-clear sky,pseudo-overcast sky and overcast sky.It is inadequate to classify sky merely from cloudage and to affirm that all sky conditions except clear and overcast belong to only one type.From the viewpoint of statis-tical average over many years,when sun disk is covered with cloud,luminance distribution of the sky resembles that of overcast sky,and when there is no cloud over sun disk,it is sim-ilar to that of clear sky.The luminance distributions of pscudo-clear sky and pseudo-over-cast sky are quite.In pseudo-overcatssky,the maximum skydifferent.In pseudo-clear sky,it gets maximum sky luminence can not appear in the region around the sun in considera-tion of the problem from the viewpoint of statistial average over many years.Furthermore,the differences of horizont.al diffuse illuminancc between pseudo-clear and pseudl-ouercast sky are obvious.Therefore it is more suitable to study all kinds of skies,that is pseudo-clear and pseudo-overcast sky.     

Return migration to Eastern Kentucky and the stem family concept

This research provides a conceptual framework--based on the stem family concept--with which to explore the cyclical nature of return migration to Eastern Kentucky. The work of Brown, Schwarzweller, and Mangalam shows how the stem family facilitates the outward movement of migrants during times of economic opportunity outside Appalachia, while providing a potential haven when sociocultural pulls within Appalachia exceed the economic tugs outside the region. Responses from 119 households in Laurel, Pike, and Powell counties are used to test hypotheses associated with the general model. The survey results support the continued existence of extreme stem family forces within Eastern Kentucky. Most immigrants are return migrants; return migration motives continue to be more related to sociocultural factors than they are job-related decisions. Most returnees are well below retirement age, and even the younger and more educated among these have a strong preference for remaining in Eastern Kentucky, although their historical tendency had been to move away when economic pulls are strong enough. The work of Brown, Schwarzweller, and Mangalam shows how the stem family facilitates the outward movement of migrants during times of economic opportunity outside Appalachia, while providing a potential haven when sociocultural pulls within Appalachia exceed the economic tugs outside the region. Overall, there is a need to better understand the role of awareness space in the destination selection of cyclical migrants.
