In the last decade, several methods were developed to determine potential supply risks due to short term socio-economic aspects. One of them is the ESSENZ method (comprehensive method to measure and assess resource efficiency of products in the context of sustainable development) developed by the authors. Due to newly available data (e.g., production statistics) the characterization factors (CFs) of the ESSENZ method were updated (based on data from the years 2011 to 2015, with focus on 2014 and 2015) and compared with the original CFs (based on data from the years 2009 to 2013, with focus on 2012 and 2013) for six of the overall eleven categories. The goal of the paper is to analyze if changes in the underlying data are adequately reflected in the CFs of ESSENZ for the considered categories. Further, the updated CFs are provided. The six categories are analyzed by comparing original and updated CFs and clustering them into four groups: declining, emerging, persistent, and non-occurring potential supply risks. Significant differences in the CFs are evaluated by analyzing changes in the underlying data as well as the steps to determine the CFs. It could be shown, that for most of the considered categories and resources changes in the underlying data are reflected adequately in the CFs. However, some methodological challenges of ESSENZ, which limit the reflection of potential supply risks changes, could also be identified.

The paper examines the Sarbanes-Oxley (2002) Acts immediate impact on board composition and characteristics as well as possible reversals in its impact over time. Effects on directors age and tenure are analyzed over the 2001-06 sample period. Female participation in corporate boards is also studied in the pre-SOX and post-SOX periods. The dual roles of directors in being a member of the board as well as serving as either CEO, CFO, Chairman, Co-Chair, Founder, or Lead Director of their respective companies is also examined. We observe a short-term impact of SOX on board compositions due to changes seen in board characteristics between 2001 (pre-SOX), and 2003-05 short-term period (post-SOX). Also, we observe a reversal of board characteristics in 2006 to pre-SOX levels implying that the effects of SOX on board composition were short-lived, and needs to be monitored over time to ensure adherence to corporate accountability guidelines over the long-term.

The study aimed to investigate the status of within-person state variability in neuroticism and conscientiousness as individual differences constructs by exploring their (a) temporal stability, (b) cross-context consistency, (c) empirical links to selected antecedents, and (d) empirical links to longer term trait variability. Employing a sample of professionals ( N = 346) from Australian organisations, personality state data together with situation appraisals were collected using experience sampling methodology in field and repeatedly in lab-like settings. Data on personality traits, cognitive ability, and motivational mindsets were collected at baseline and after two years. Contingent (situation contingencies) and non-contingent (relative SD) state variability indices were relatively stable over time and across contexts. Only a small number of predictive effects of state variability were observed, and these differed across contexts. Cognitive ability appeared to be associated with state variability under lab-like conditions. There was limited evidence of links between short-term state and long-term trait variability, except for a small effect for neuroticism. Some evidence of positive manifold was found for non-contingent variability. Systematic efforts are required to further elucidate the complex pattern of results regarding the antecedents, correlates and outcomes of individual differences in state variability.

AbstractPolychlorinated biphenyls (PCBs) were added to certain marine vessel bottom paints as a plasticizer to improve the adhesion and durability of the paint. The most common PCB formulation used to amend such paints was Aroclor 1254. Fugitive Aroclor-containing paint chips generated from vessel maintenance and repair operations represent a potential source of PCB contamination to sediments. Limited published studies indicate that Aroclor-containing paint is largely inert and exhibits low PCB leaching into water; however, the rate and degree of leaching of PCBs from paint chips have not been directly studied. This laboratory-based study evaluated the rate and extent of leaching of PCBs from paint chips into freshwater. The results of this investigation demonstrate that the rate of PCB dissolution from paint chips decreased rapidly and exponentially over time. Based on this study, it is estimated that the rate of leaching of PCBs from paint chips would cease after approximately 3 years of exposure to water. When all leachable PCBs were exhausted, it is estimated that less than 1% of the mass of PCBs in the paint chips was amenable to dissolution. The results of this experiment suggest that Aroclor-containing paint chips found in sediments are likely short-term sources of dissolved-phase PCB to pore or surface waters and that the majority of the PCBs in paint chips remain in the paint matrix and unavailable for partitioning into water.

AbstractWe analyze the mortality of couples by fitting a multiple state model to a large insurance data set. We find evidence that mortality rates increase after the death of a partner and, in addition, that this phenomenon diminishes over time. This is popularly known as a “broken-heart” effect and we find that it affects widowers more than widows. Remaining lifetimes of joint lives therefore exhibit short-term dependence. We carry out numerical work involving the pricing and valuation of typical contingent assurance contracts and of a joint life and survivor annuity. If insurers ignore dependence, or mis-specify it as long-term dependence, then significant mis-pricing and inappropriate provisioning can result. Detailed numerical results are presented.

Three techniques for assessing extension of one's personal future (line-marking, open-ended report, life-events) were compared in a sample of 74 respondents. Two points of data collection were employed to examine short-term stability. At both administrations, correlations among indices suggested that techniques were only moderately comparable. Short-term stabilities were variable; correlations ranged from .42 to .79. Across subgroups of the sample, the direct, open-ended report of extension showed the greatest stability, while life-event extension showed the least. Apparently, extension of thinking about the future should be assessed by more than one technique to investigate potential relationships with other variables or changes over time in perspective about the future.

PurposeSustainability-oriented strategies involve considering all possible environmental, social and economic factors that impact stakeholders and sustainable development. They could be a crucial contribution of the private sector to Sustainable Development Goals (SDGs). The study’s objective is twofolded. First, the authors want to discover if enterprises doing business in Brazil are contemplating the SDGs in their strategies. Second, the authors want to identify the external and internal factors that motivate them.Design/methodology/approachThe authors collected data through an online survey with employees from Global Compact signatories in Brazil. From a list of 335 for-profit enterprises, the authors got back 132 answers. The sample comprises Brazilian enterprises that only operate in the Brazilian market, Brazilian multinational enterprises (MNEs) and foreign multinationals operating in Brazilian and international markets. For this study, the MNEs’ group comprises Brazilian multinationals and foreign multinationals (MNEs). To characterize the sample and identify the motivating factors, the authors conducted a descriptive analysis. To compare the domestic and MNEs’ mean differences regarding the factors that influenced their strategies and the SDGs, the authors performed Mann–Whitney's U-test.FindingsThe results of the study show that enterprises are addressing the SDGs in their strategies. All internal and external driving factors are similar for domestic and MNEs, except for the value chain's negative externalities. MNEs are more prone to consider their negative externalities, which is a positive trend. Finally, results suggest that both groups of enterprises consider the 17 goals in their strategies, contrary to the theoretical argument that multinationals suffer more pressure because of their broad geographic scope.Research limitations/implicationsThe database of the study involves data collected through a self-response survey. Thus, the authors cannot discuss the effectiveness of real SDGs' strategies once enterprises' discourse on sustainability does not always correspond with practices. Therefore, the authors suggest that researchers address the results of implemented strategies on the SDGs over time to check for improvements and new developments.Practical implicationsThe authors suggest frequent materiality assessment of domestic enterprises' supply chain and articulation of explicit purposes around the selected SDGs, including setting key performance indicators (KPIs) and monitoring progress.Social implicationsThe authors believe that enterprises and decision makers should recognize their essential role to bend the curve on SDGs and shift their behavior toward strategic choices that could contribute to their positive performance over time, without contributing to environmental degradation and socioeconomic chaos.Originality/valuePublication on how enterprises address the SDGs in Brazil is relatively scarce. This study provides some answers to that by focusing on the factors influencing sustainability-oriented strategies on the SDGs. Besides, most previous studies consider a small sample of enterprises and are industry specific or focus on the effects of the SDGs in public policy. The sample of this study is diverse and represents 42% of the for-profit signatories of the Global Compact in Brazil.

AbstractThis paper studies the existence of a world business cycle by examining quarterly and annual comovements in production, prices and interest rates in the three main world economies: Germany, Japan and the US. In accordance with earlier studies, contemporaneous relationships clearly dominate short-term dynamics. The evidence indicates the existence of strong comovements in prices and long-term interest rates, and, to a lesser degree, in GDP and short-term interest rates. They are, however, rather unstable over time.

(1) Background. Defeat and entrapment have been highlighted as major risk factors of suicidal ideation and behavior. Nevertheless, little is known about their short-term variability and their longitudinal association in real-time. Therefore, this study aims to investigate whether defeat and entrapment change over time and whether defeat predicts entrapment as stated by the integrated motivational–volitional model of suicidal behavior. (2) Methods. Healthy participants (n = 61) underwent a 7-day smartphone-based ecological momentary assessment (EMA) on suicidal ideation/behavior and relevant risk factors, including defeat and entrapment and a comprehensive baseline (T0) and post (T2) assessment. (3) Results. Mean squared successive differences (MSSD) and intraclass correlations (ICC) support the temporal instability as well as within-person variability of defeat and entrapment. Multilevel analyses revealed that during EMA, defeat was positively associated with entrapment at the same measurement. However, defeat could not predict entrapment to the next measurement (approximately two hours later). (4) Conclusion. This study provides evidence on the short-term variability of defeat and entrapment highlighting that repeated measurement of defeat and entrapment—preferably in real time—is necessary in order to adequately capture the actual empirical relations of these variables and not to overlook significant within-person variability. Further research—especially within clinical samples—seems warranted.
