Are diamonds a safe haven?

The diamond market has recently experienced important structural changes moving from a monopolistic market to a more liberalised and competitive one. As a result, diamonds are being discussed as a new investment asset class, with possible valuable portfolio contributions. The aim of this paper is to analyse their potential role within an investment framework, using previously unpublished data. We use the GemShares and NASDAQ OMX patented license and Polished Prices proprietary Price Reporting Agency (PRA) database to build our own standardized financial polished diamond basket indices (DBIs), using actual reported data of traded prices, adjusted for liquidity by traded volume. The impact of adjusting for traded volume of investment grade (only) diamonds is sufficient to develop a unique subset different to that captured and reported by the PRA. We first construct an index for High-Quality (HQ) and a second one for Medium-Quality (MQ) diamonds so we can study both of their dynamics and investment features. We further analyse the relationship the two indices have with major macroeconomic and financial variables, as well as other precious commodities to investigate their role as safe haven or hedge. We find that the DBI_HQ Index returns are, on average, positively correlated with major macroeconomic variables—in particular with the Euro and Chinese Interest rates. The DBI_MQ Index returns are largely uncorrelated with the same macroeconomic variables—with the exception of Euro Interest rates and the Israeli Exchange rate. When we compare our Diamond Indices returns with major financial variables and other precious commodities, we find a broad lack of correlation between their returns, and significant difference between the DBI_HQ and DBI_MQ Indices. We may conclude that diamonds are broadly a poor hedge for any of the portfolios we considered, with a few important exceptions—especially gold. Using Bauer and Lucey’s (Financ Rev 45(2):217–229. doi: 10.2139/ssrn.952289, 2010) approach we further tested the “safe haven value” and “hedging usefulness” of the two Indices. In contrast with previous studies we believe the unique data we accessed allowed us to demonstrate that diamonds represent a strong hedge for gold investors, and in addition exhibit features of a safe haven for stock markets during periods of financial stress.     

Initial Career and Work Meanings in Seven European Countries

This study explores the initial careers of two target groups of young adults in seven European countries. Career patterns have been constructed through cluster analysis on data gathered from the young adults through a retrospective self-report procedure covering a period of 2.5 years. Six career patterns have been identified across countries by the activities taking place (employment, various educational preparations, unemployment, military or civil service) and have been further described by personal and work-related variables as well as by meaning of work indices (work centrality, intrinsic versus extrinsic work orientations, and societal norms about working) and psychological well-being in the second year on the labor market. Suggestions for further research as well as the implications for career counseling, career education, organizational career guidance and development have been given.     

Money Management Patterns of Dual-Earner Families in Israel

The purpose of the present study is to assess money organizing patterns and banking arrangements in dual-earner families and how they are affected by both the economic and social context. A log linear analysis of data from the International Social Survey Program for working couples in Israel indicates that the combination of money organizing patterns and banking arrangements enables meaningful distinction between traditional, modern and individualistic spousal economic behavior modes. A further comparison of demographic, employment and attitudinal effects suggests that both the economic and social context approaches are necessary to identify the factors associated with different spousal economic behavior modes. Both the spouses' labor force positions and their attitudes regarding family roles contribute to their using a particular mode.     

Graduate education in sociology: What do we need to do differently?

Research methods should be the core of a sociology curriculum, but they need to be taught with more emphasis on application and with greater recognition of the importance of managerial and communicative skills. Participation in practicums or where feasible, internships in the private or public sector, should be part of that research training. Departments should select areas of specialization within sociology that reflect the faculty’s expertise, the university’s strengths or distinctiveness, and the social, economic and demographic characteristics of the area. But such basic sub-fields as history, stratification, theory, social psychology, demography and social organization must be included in every curriculum. How to go about selecting a worthwhile research problem and how to communicate results are skills that should be taught in a graduate program. She has been working on immigrants and U.S. immigration policy, and her most recent publication isInternational Migration: The Female Experience (co-edited with Caroline Brettell).     

An assessment of the accuracy of a regional economic-demographic projection model

A large number of regional economic-demographic projection models have been developed but their accuracy has seldom been evaluated. This article examines the accuracy of one such model in projecting total populations for 1980, using 1970 base data, for 106 counties and 553 places in two states. Comparisons of the model's projections to 1980 Census counts reveal mean percentage absolute differences of 10 percent for counties and 14 percent for places. In addition, the model's accuracy was comparable to that for alternative projection systems. When projections for places of less than 1,000 are excluded, differences are substantially reduced. Economic-demographic models appear to be quite useful and deserve further attention.     

Workplace support, role overload, and job satisfaction of direct care workers in assisted living

This study aims to enhance our understanding of job satisfaction of direct care workers in assisted living facilities. Low job satisfaction is related to high turnover rates and lower quality of care in assisted living. We integrate two theories of job satisfaction to investigate relationships among workplace support, role overload, and job satisfaction. Data are from a survey of 984 direct care workers in 108 assisted living facilities. Results from multilevel hierarchical linear models (HLM) indicate that job satisfaction varies both within and among facilities. Job satisfaction is negatively associated with role overload, and it is positively associated with institutional support, supervisor instrumental and emotional support, and coworker emotional support. These workplace support measures and role overload are separately and independently associated with job satisfaction. Enhancing job satisfaction of assisted living direct care workers will likely require a multipronged approach that includes improving institutional, supervisor, and coworker support while simultaneously directly addressing role overload.     

Gender nonconformity, homophobia, and mental distress in latino gay and bisexual men

This study explored whether gender nonconformity in gay and bisexual men is related to mental distress and if so, whether this relationship is mediated by negative experiences that are likely associated with gender nonconformity, including abuse and harassment. To study this question, data were analyzed from face-to face interviews with 912 self-identified gay and bisexual Latino men in three major U.S. cities collected by Diaz and colleagues (2001). Gay and bisexual Latino men who considered themselves to be effeminate had higher levels of mental distress and more frequently reported various negative experiences, compared with gay and bisexual Latino men who did not identify as effeminate. Higher levels of mental distress in effeminate men seemed to primarily result from more experiences of homophobia. Findings suggest the need for more attention to gender in research as well as counseling of sexual minority men.     

Estimating Listeria monocytogenes Growth in Ready-to-Eat Chicken Salad Using a Challenge Test for Quantitative Microbial Risk Assessment

Currently, there is a growing preference for convenience food products, such as ready-to-eat (RTE) foods, associated with long refrigerated shelf-lives, not requiring a heat treatment prior to consumption. Because Listeria monocytogenes is able to grow at refrigeration temperatures, inconsistent temperatures during production, distribution, and at consumer's household may allow for the pathogen to thrive, reaching unsafe limits. L. monocytogenes is the causative agent of listeriosis, a rare but severe human illness, with high fatality rates, transmitted almost exclusively by food consumption. With the aim of assessing the quantitative microbial risk of L. monocytogenes in RTE chicken salads, a challenge test was performed. Salads were inoculated with a three-strain mixture of cold-adapted L. monocytogenes and stored at 4, 12, and 16 °C for eight days. Results revealed that the salad was able to support L. monocytogenes’ growth, even at refrigeration temperatures. The Baranyi primary model was fitted to microbiological data to estimate the pathogen's growth kinetic parameters. Temperature effect on the maximum specific growth rate (μ_max) was modeled using a square-root-type model. Storage temperature significantly influenced μ_max of L. monocytogenes (p < 0.05). These predicted growth models for L. monocytogenes were subsequently used to develop a quantitative microbial risk assessment, estimating a median number of 0.00008726 listeriosis cases per year linked to the consumption of these RTE salads. Sensitivity analysis considering different time–temperature scenarios indicated a very low median risk per portion (<−7 log), even if the assessed RTE chicken salad was kept in abuse storage conditions.     

Women against the state: Political opportunities and collective action frames in chile's transition to democracy

While transitions to democracy have been hailed as the most important phenomena of this century, few scholars understand the role that women have played in these metamorphoses. This article uses an historical in-depth case study to examine how and why women mobilized against the state in Chile. Previous social movement theories have not attended adequately to cultural and ideational elements (e.g., gender ideology), much less these factors in the Third World and authoritarian context. In contrast, the present study modifies and extends the concepts of political opportunity structure and collective action frames, suggesting that the manner in which ideology and cultural themes are framed may provide opportunities for protest, especially in the authoritarian context. Specifically, the rise and fall of broader mobilizational frames or master frames shapes how movement-specific frames compete, decay, and transform, as some master frames create space for certain ideas (e.g., feminism) while others do not. New hypotheses regarding the use of collective action frames in a nondemocratic setting are offered.This article was presented at the American Sociological Association annual meeting, Miami, Florida, August 1993.
