Deciphering the epidemiology of hepatocellular carcinoma through the passage of time: A study of 1,401 patients across 3 decades

Hepatocellular carcinoma (HCC) is one of the most common and lethal cancers globally. With advances in therapy for chronic viral hepatitis, changing social circumstances, and increasing practice of HCC surveillance, the epidemiology of HCC is expected to change over time. We explored the temporal trends in HCC in Singapore, a multiethnic Asian country, over the last 3 decades. Patients with HCC were prospectively enrolled and stratified into two cohorts (C1, 1988‐2002; C2, 2003‐2016). Patient and tumor characteristics, management, and survival were compared between the two cohorts, and a survival census was performed on October 31, 2015. There were 1,401 patients, and the mean age at diagnosis of HCC for C1 and C2 was 60.1 and 63.5 years, respectively. Male patient preponderance decreased significantly, with the male to female ratio falling from 5.2:1 to 3.9:1 between C1 and C2. Hepatitis B, although still the predominant risk factor for HCC, showed a significant decline from C1 to C2 (76.5% to 68.2%), while the nonviral etiology increased significantly over the same period (14.4% versus 25.0%, respectively). Significantly more patients in C2 than C1 were diagnosed through surveillance (39.2% versus 11.3%, respectively) and had better physical performance (Eastern Cooperative Oncology Group 0, 62.1% versus 20.4%, respectively). While Child‐Pugh status was comparable, significantly more patients in C2 than C1 had early stage disease (Barcelona Clinic Liver Cancer 0‐A, 39.5% versus 7.4%, respectively), which translated into significantly higher median survival (18.6 months versus 3.8 months, respectively). Conclusion: Over the past 3 decades, hepatitis B‐related HCC has been decreasing while HCC due to nonviral etiology has been increasing significantly. Surveillance to diagnose early stage HCC is important in improving the outcome of HCC. (Hepatology Communications 2017;1:564–571)
Review of the genus Agria (Diptera, Sarcophagidae) from China

Abstract Agria mihalyii (Rohdendorf and Verves, 1978) is recorded from China for the first time, and both sexes are thoroughly documented using a combination of illustrations, photographs and scanning electron microscopy images. The generic affiliation is corroborated from an expanded definition of genus Agria Robineau-Desvoidy, 1830, and a key to males of the two known species from China is provided. The distribution of coeloconic sensilla on the male pre- and postgonite are shown to possess significant diagnostic and phylogenetic information in this genus.
Developmental timing and continuity of exposure to interparental violence and externalizing behavior as prospective predictors of dating violence

Abstract This study investigated the prospective pathways of children's exposure to interparental violence (EIPV) in early and middle childhood and externalizing behavior in middle childhood and adolescence as developmental predictors of dating violence perpetration and victimization at ages 23 and 26 years. Participants (N = 168) were drawn from a longitudinal study of low-income families. Path analyses examined whether timing or continuity of EIPV predicted dating violence and whether timing or continuity of externalizing behavior mediated these pathways. Results indicated that EIPV in early childhood directly predicted perpetration and victimization at age 23. There were significant indirect effects from EIPV to dating violence through externalizing behavior in adolescence and life stress at age 23. Independent of EIPV, externalizing behavior in middle childhood also predicted dating violence through externalizing behavior in adolescence and life stress at age 23, but this pathway stemmed from maltreatment. These results highlight that the timing of EIPV and both the timing and the continuity of externalizing behavior are critical risks for the intergenerational transmission of dating violence. The findings support a developmental perspective that negative early experiences and children's externalizing behavior are powerful influences for dating violence in early adulthood.
SOCIAL SECURITY BENEFITS AND EMPLOYER BEHAVIOR: EVALUATING SOCIAL SECURITY EARLY RETIREMENT BENEFITS AS A FORM OF UNEMPLOYMENT INSURANCE*

Employers often shed older workers by encouraging them to "take" early retirement. An implicit contract model suggests that this behavior will be influenced by the social security early retirement program. When demand is weak and layoffs are necessary, social security benefits can act like a form of unemployment insurance, effectively subsidizing workforce reductions by lowering the cost to the firm of shedding older workers. Since social security benefits are not subject to experience rating, the result is an inefficiently high level of early retirements. This paper concludes with a discussion of policies for restoring early retirements to efficient levels.

Office building conversion and sustainable adaptation: a comparative study

Purpose – The City of Melbourne seeks to retrofit 1,200 CBD properties by 2020 as part of the strategy to become carbon neutral, whilst Amsterdam aims to cut CO2 emissions 40 per cent by 2025. Oversupply in the Amsterdam office market makes conversion to residential use viable. In examining converted buildings in Amsterdam and the Melbourne CBD typical attributes of converted stock can be identified to target retrofit measures. This paper seeks to focus on these initiatives.Design/methodology/approach – In Amsterdam five case studies were undertaken to reveal and define building attributes that explain the viability of these conversions. On the other hand, the Melbourne study was based on a database assembled containing all Melbourne CBD office building adaptations carried out between 1998 and 2008. The research analysed the conversion of office buildings and the scope for sustainable retrofit evaluating a limited number of attributes known to be important in adaptation.Findings – The outcomes of this res.
Assessing the impact of skill shortages on the productivity performance of high-tech firms in Northern Ireland

This article utilizes data from three separate skill related surveys of firms in the Northern Ireland IT, Electronic Engineering and Mechanical Engineering industries in order to assess the extent to which the performance of high-tech firms are being constrained as a result of hard-to-fill and/or unfilled vacancies. Whist it was found that the determinants of skill shortage varied somewhat depending upon the definitional approach adopted, a high degree of correlation was found. With regards to the impacts of skill shortages on firm level performance, it was found that both hard-to-fill and unfilled vacancies had reduced output per worker levels by between 65 and 75% in affected firms, however, these impacts were only detecw after controlling for selection effects. The evidence suggests that standard OLS procedures can generate highly misleading results in studies of this nature.
Epizootiologic Role of Feeds in the Epidemiology of Salmonella Senftenberg Contamination in Commercial Layer Farms in Eastern Japan

SUMMARY. In total, 40 commercial layer farms and 32 replacement pullet farms with a combined population of 7.5 million adult layers and 6.6 million replacement pullets from six prefectures in eastern Japan were investigated for Salmonella Senftenberg contamination. We randomly collected 17,956 environmental samples, 5816 feed samples, and 218,470 egg samples from commercial layer farms; and 427 feed samples and 2896 environmental samples from replacement pullet farms. We monitored all samples for Salmonella. Samples were primarily enriched in Hajna tetrathinoate broth for 24 hr at 37 C followed by incubation in desoxycholate hydrogen sulfide lactose agar for 18 hr at 37 C. Salmonella colonies were confirmed and identified by biochemical tests and serotyped using Salmonella O and H antigens. We recorded 171 environmental samples (0.95%) and 10 feed samples (0.17%) that were positive for Salmonella spp. in which 36 environmental samples (0.20%) and six feed samples (0.10%) were identified as Salmonella Senftenberg. All Salmonella Senftenberg strains were isolated from nine replacement pullet farms. No Salmonella Senftenberg strains were isolated from adult layer farms and from eggs. Pulse field gel electrophoresis of BlnI-digested chromosomal DNA of 19 Salmonella Senftenberg isolates from feeds and environmental samples yielded a single identical DNA pattern. Traceback information showed that all positive feed samples were from a single feed source. Timeline studies showed that Salmonella Senftenberg contamination occurred first mostly in the feeds and then spread to the environment and other farms. This study demonstrated that the prevalence of Salmonella Senftenberg contamination in commercial layer facilities in eastern Japan is very low. Moreover, feed contamination played a major role in the epizootiology and spread of this pathogen in commercial poultry flocks. Given the resilient and persistent nature of this particular Salmonella serotype, routine monitoring and strict quality control measures at the feed level are recommended to prevent the colonization of poultry facilities with Salmonella Senftenberg that may lead to future outbreaks.
Assessing the Quality of a Local Authority Conference and Hospitality Venue Using the ServQual Model

Abstract The close attention paid to service quality by successful private companies has become part of the environment within which most public service organizations now operate. The ServQual model has been used with success to help companies quantify customers' expectations and perceptions of their service and to use this analysis as the basis for improvement. More recently, the ServQual approach has been applied in public service contexts with mixed reliability and validity. This paper reports on the application of the ServQual model to a conference and hospitality venue operated by a Scottish local authority. The study investigates five distinct customer segments: conferences, meetings, receptions, performances, and weddings. The expectations-perceptions gaps are assessed for each of these segments using the ServQual model and the size and antecedents of ServQual Gap 1 is also examined.
Trade Restrictiveness in the CEMAC Region - The Case of Congo

Congo's vital dependence on trade for development stands in contradiction with its trade policy. As a member of the CEMAC, Congo's tariff scheme at least formally is guided by CEMAC's 1994 trade regime agreement. This paper shows CEMAC's customs code is restrictive relative to that of comparable regional integration groups. The paper also discusses a number of quantitative and qualitative barriers to trade applied by Congo that render its current regime complex, nontransparent, and relatively unpredictable, compromising efforts to develop the non-oil sector and the country's export base. Moreover, Congo's high tariffs and other taxes have not led to higher fiscal revenues, as the number of exemptions granted in recent years has surged and customs administration remains weak.
Earnings Momentum and Earnings Management

This paper provides evidence on firms that report long “strings” of consecutive increases in earnings per share (EPS). First, we find 746 firms that report earnings strings of at least twenty quarters since 1962, and show that this frequency is much larger than would be expected by chance. We interpret this as prima facie evidence of earnings management. Next, we document that these firms enjoy abnormal returns that average more than 20 percent per year during the first five years of these strings, and these returns are larger than those of firms reporting at least five years of consecutive increases in annual (but not quarterly) EPS. We argue that these market premia, and the rapidity with which they disappear once the strings end, provide managers with incentives to maintain and extend the strings. Finally, we present several tests that document how managers of these firms use various earnings management tools to help their firms sustain and extend these strings.
Legal Origins: Reconciling Law & Finance and Comparative Law

In the last few years law and finance scholars have 'discovered' the usefulness of comparative law. Their studies look at the quantifiable effect that legal rules and their enforcement have on financial development in different countries. Moreover, they link their results with the long- standing distinction between Civil Law and Common Law countries. Whether this revival of 'legal families' is a useful way forward is, however, a matter of debate. The following article challenges these studies and looks for characteristic features which are more precise and meaningful than the use of legal families as such.
Consumer Attitudes and the Epidemiology of Inflation Expectations

This paper studies the formation of consumers’ infl‡ation expectations using micro-level data from the Michigan Survey. It shows that beyond the well-established socio-economic determinants of infl‡ation expectations like gender, income or education also other characteristics like the household’s fi…nancial situation and its purchasing attitudes matter. Respondents with current or expected …financial difficulties, with pessimistic attitudes about major purchases, or who expect income to go down in the future have considerably higher forecast errors, are further away from professional forecasts and have a stronger updward bias in their expectations than other households. However, their bias shrinks by more than the one of the average household in response to increasing media reporting about in‡flation.
Review of trade-offs and co-benefits from greenhouse gas mitigation measures in agricultural production

Anthropogenic release of greenhouse gasses (GHG) has increased in the last 50 years, contributing to global climate change. Because agriculture is one of the major contributors to the production of non-CO2 GHG, the opportunities for mitigating GHG emissions from agriculture are often considered by policy makers. However, the implementation of agricultural GHG mitigation policies can have unintended consequences or trade-offs (both negative and positive). A major problem, for policy makers, is that although most of these trade-offs have been described in the past, no overview of them exists; and in many cases, there is no consensus with regard to the impact of the mitigation measures on aspects such as cost effectiveness, social acceptance, environmental impact, etc. The current article gives an overview of the different kinds of trade-off that might occur and their relationships to GHG mitigation and agricultural production. The authors offer policy makers a framework which can be applied to any GHG mitigation measure to determine which trade-offs are the most important and which ones should be taken into consideration. This will help policy makers to create an optimal agricultural GHG mitigation measure.
Social Norms, Savings Behavior, and Growth

We argue that many goods and decisions are not allocated or made through markets. We interpret an agent's status as a ranking device that determines how well he or she fares in the nonmarket sector. The existence of a nonmarket sector can endogenously generate a concern for relative position in, for example, the income distribution so that higher income implies higher status. Moreover, it can naturally yield multiple equilibria. It is thus possible to explain differences in growth rates across countries without recourse to differences in underlying preferences, technologies, or endowments. Different social organizations lead to different reduced-form preferences, which lead to different growth rates.
Labor Statistics Measurement Issues

Rapidly changing technology, the globalization of markets, and the declining role of unions are just some of the factors that have led to dramatic changes in working conditions in the United States. Little attention has been paid to the difficult measurement problems underlying analysis of the labor market. Labor Statistics Measurement Issues helps to fill this gap by exploring key theoretical and practical issues in the measurement of employment, wages, and workplace practices. Some of the chapters in this volume explore the conceptual issues of what is needed, what is known, or what can be learned from existing data, and what needs have not been met by available data sources. Others make innovative uses of existing data to analyze these topics. Also included are papers examining how answers to important questions are affected by alternative measures used and how these can be reconciled. This important and useful book will find a large audience among labor economists and consumers of labor statistics.
Relative Validity of a Short Food Frequency Questionnaire for Assessing Nutrient Intake versus Three-day Weighed Diet Records in Middle-aged Japanese

BACKGROUND: Validation studies on brief food frequency questionnaires (FFQs) for measuring consumption of macro- and micro-nutrients for the general populace are not fully executed in Japan. METHODS: Two hundred and two middle-aged Japanese (73 males and 129 females) in Aich Prefecture, Japan completed an FFQ and 3day-weighed diet records (3d-WDRs) in February 2004. We compared intakes of energy and 26 nutrients computed with the FFQ against those with the 3d-WDRs as a reference. RESULTS: Mean daily intakes of selected nutrients determined with the FFQ were generally less than those with 3d-WDRs. The ratios assessed with the FFQ vs. 3d-WDRs (minimum - median - maximum) were distributed from 0.57 - 0.79 - 1.09 for males, and 0.61 - 0.86 - 1.04 for females. De-attenuated, log-transformed and energy-adjusted Pearson’s correlation coefficients between intakes of selected nutrients quantified with both devices were distributed from 0.12 - 0.45 - 0.86 and energy-adjusted Spearman’s rank correlation coefficients were from 0.13 - 0.35 - 0.76, for males. The respective values for females were 0.10 - 0.38 - 0.66, and 0.11 - 0.34 - 0.47. Median percentages for exact agreement, agreement within adjacent categories, and disagreement according to quartile classification of the energy-adjusted nutrient intakes measured with both methods were 33, 74, and 5 for males, and 35, 76, and 7 for females, respectively. CONCLUSION: Satisfactorily high relative validity indices of most nutrient intakes computed with the FFQ were attained against those with the 3d-WDRs. The questionnaire therefore appears applicable for categorizing individuals according to consumption of energy and selected nutrients in dietary studies of middle-aged Japanese.
Multi‐perspective strategic goal setting, performance reporting and organisational performance

Purpose – This paper's aim is to study multi‐perspective strategic goal setting and performance reporting systems and investigate: if the strength of the alignment of the goals and performance measures is associated with organisational performance and if performance reporting emphasis (PRE) is associated with performance.Design/methodology/approach – Structured interviews with CEOs of 50 Australian companies with sales greater than $100 million per annum were conducted.Findings – The research identified 11 dimensions of PRE and 13 dimensions of organisational performance. The strength of the alignment of the strategic goals and the performance reporting measures was positively associated with organisational performance. PRE was positively associated with organisational performance. The alignment finding was the stronger of the two.Originality/value – The research identified several dimensions of performance reporting that organisations might consider using in their performance reporting systems. The findi.
Institutional and structural barriers for implementing on-farm water saving irrigation systems

Abstract Population growth and increased global water demand has intensified the need to apply water more efficiently. As the main global water user the agricultural sector needs special attention. In this study, the water saving potential of new drip irrigation systems has been investigated in five different regions in Europe and China. From a technical point of view, these solutions have a high potential to increase the water application efficiency at the farm level. In practice, however, farmers often have low economic incentives to adopt these technical solutions. This study assesses the likely institutional and structural barriers for shifting to more water efficient technologies on farms. To deal with the lack of incentives, a holistic and multidisciplinary assessment approach has been taken to cover the various parameters that may influence farmers' choice of technology. A case study analysis has been designed to collect information on agricultural practices, irrigation systems, water availability, and water administrations in five regions in Greece, Italy, Serbia and China from the EU funded research project SAFIR. Findings from this case study analysis indicate that the incentives to shift to new water saving technologies are low in many of these regions due to low profitability of water savings and various institutional and structural barriers. On Crete, however, attempts have been made with regulation and volumetric water levies, resulting in the adoption of water saving technology. In the two case-regions in Beijing and Henan province in China, there is little incentive for farmers to save water. Instead, attempts in China have been made to deal with water scarcity by using treated waste water for agricultural production. Finally, a number of administrative and economic solutions are suggested to improve incentives to save water among farmers.
Improving Wikipedia's accuracy: Is edit age a solution?

Wikipedia is fast becoming a key information source for many despite criticism that it is unreliable and inaccurate. A number of recommendations have been made to sort the chaff from the wheat in Wikipedia, among which is the idea of color-coding article segment edits according to age (Cross, 2006). Using data collected as part of a wider study published in Nature , this article examines the distribution of errors throughout the life of a select group of Wikipedia articles. The survival time of each “error edit” in terms of the edit counts and days was calculated and the hypothesis that surviving material added by older edits is more trustworthy was tested. Surprisingly, we ﬁnd that roughly 20% of errors can be attributed to surviving text added by the ﬁrst edit, which conﬁrmed the existence of a “ﬁrst-mover” effect (Viegas, Wattenberg, & Kushal, 2004) whereby material added by early edits are less likely to be removed. We suggest that the sizable number of errors added by early edits is simply a result of more material being added near the beginning of the life of the article. Overall, the results do not provide support for the idea of trusting surviving segments attributed to older edits because such edits tend to add more material and hence contain more errors which do not seem to be offset by greater opportunities for error correction by later edits.
