Fracture behaviour of alloys for a new laser ranged satellite

A new laser-ranged satellite called LARES 2 (Laser Relativity Satellite 2) has been recently designed for accurate tests of Einsten's theory of General Relativity and space geodesy. Some high density alloys (8.6-9.3 g/dm3) have been studied and characterised for producing the LARES 2 passive satellite. The considered materials were Copper and Nickel based alloys that have been produced and characterised. Aim of this work was to analyse their fracture behaviour that is a requirement for materials to be used for space applications. Fracture tests have been carried out on several specimens and fracture surfaces have been analysed

Health Seeking Behavior In Bulak Banteng, Surabaya

Infant and under-five mortality rate in the world is still a major health problem that must be resolved immediately. Mother's health seeking behavior very important to manage the health of his children. Purpose of this study was to investigate health seeking behavior among mothers when their children were sick. This study was descriptive quantitative involved 50 respondents. The results show majority mothers choose to take action when their children are sick with most choosing to take them to health care facilities and do their own treatment. Mothers are expected to always care for their children well and not too late for giving treatment when their children are sick

How Do Emotions Influence Saving Behavior

Employers have moved away from traditional defined benefit pension plans to defined contribution plans such as 401(k)s. As a result, many individuals are now required to make their own retirement saving and investment decisions, which has raised concerns about their ability and desire to handle these decisions. Since investment choices have major implications for future financial welfare, it is important to understand how individuals make these decisions and to identify potential ways to improve the decision-making process. Researchers have explored various factors affecting retirement saving, such as income, age, job tenure, self-control failure, financial literacy and trust. No prior research, however, has looked at the effects of emotions on retirement savings. This Issue in Brief examines how two different emotions – hope and hopefulness – affect 401(k) participation and asset allocation. The first section defines the terms. The second section describes the structure of a recent field experiment. The third section summarizes the results, which reveal that having high hope (i.e. yearning) – for a secure retirement leads to different investment behaviors than having high hopefulness (i.e. perceived likelihood). Furthermore, threats to hope and threats to hopefulness are found to have different effects on 401(k) participation and investment decisions. The final section concludes.

Prisoner Behavior, Staff Response: Using Prison Discipline Records

This study is based on official monthly summaries of violations reviewed by the prison discipline committee that were collected over a twenty-month period (September 1978 to May 1980) at the Indiana Reformatory, a maximum security prison for adult male felons.Official prison misconduct records are used to test some of the assumptions inherent in previous research based upon such records. Many of these studies used prison data to measure changes in prisoner behavior, while others used them to indicate changes in the actions and attitudes of prison staff. Analysis of one prison's official discipline records over a 30-month period reveals flaws in both approaches. The same data cannot serve to draw conclusions about both groups though they can provide information about both when supplemented with other research methods. Conclusions drawn from official prison misconduct records are more reliable when used to assess the end of the prison discipline process — assessing discretionary decisionmaking by staff — than at the beginning of the process — evaluating prisoner behavior.[Introduction] / Background of the Study / A Case Study of Prison Discipline Records / Conclusion / Notes / References / Figure
