Fertility control in historical China revisited: New methods for an old debate

We revisit the debate over the deliberate control of reproduction in historical China through a reanalysis of data from the Qing (1644–1911) Imperial Lineage that accounts for physiological or other differences between couples that affected their chances of having children. Even though studies of contemporary and historical European fertility suggest that failing to control for such differences may obscure evidence of parity-specific control, previous studies of historical Chinese fertility have not accounted for them. We show that in the Lineage, failure to account for such differences leads the association between the number of children already born and the chances of having another birth to appear to be positive, but that once they are accounted for properly, the relationship is inverted. Based on this, we conclude that lineage members adjusted their reproductive behavior based on the number of children. We also show that the sex composition and survival of previous births affected reproductive behavior. We conclude by suggesting that one way forward in the ongoing debate over fertility control in historical China is through application of such methods to other datasets and comparison of results. We also suggest that progress in the debate over fertility in historical China has been impeded by confusion over the definition of fertility control, so that some behaviors are recognized as fertility control by some parties in the debate but not others.     

主观证明责任逻辑的中国解释

主观证明责任逻辑在我国长期处于支配地位,其影响可能超出我们的想象,这可归结为六个因素:一是民事诉讼过程的行为特征;二是举证汉语表述的行为倾向;三是作为客观证明责任前提的事实真伪不明在主观证明责任逻辑中可以被省略;四是主观证明责任逻辑可与客观真实理念和平共处;五是主观证明责任逻辑是职权主义模式选择的产物;六是我们对客观证明责任逻辑的认识偏差导致其功能被低估。     

Assessment of the cause and mode of death of victims of a mass industrial accident in the Halemba coal mine

On 21 November 2006 in the Halemba coal mine, Ruda ?l?ska, a mass industrial accident occurred. The underground catastrophe was probably due to combustion of methane followed by explosion of pulverised coal and resulted in death of twenty-three miners. The occurrence has been acknowledged to be one of the most serious accidents in Polish mining industry. Post-mortem examinations of the deceased were carried out in Department of Forensic Medicine, Medical University of Silesia, and in some cases additional dissecting techniques were employed. Photographs were taken as well as numerous specimens for various laboratory tests were collected. Toxicological analyses of blood samples revealed high levels of carboxyhaemoglobin saturation in seventeen cases, and detected presence of methane in the lungs of seven individuals, whereas microscopic specimens mainly showed lesions characteristic of putrefaction. The post-mortem procedures eventually allowed to establish the cause of death of all victims. The authors attempt to determine a range of requisite medico-legal proceedings and examinations that should be carried out in case of a mass industrial accident, and emphasise the need for development of appropriate guidelines.     

Entrepreneurial orientation and generic competitive strategies for emerging SMEs: Financial and nonfinancial performance perspective

In the competitive markets, business ventures have not only emphasized financial performance but nonfinancial performance has also become the need of the day due to its significant role in increasing customers. However, minor attention is given to the relationship between entrepreneurial orientation, business strategy and nonfinancial performance of emerging small and medium enterprises (SMEs). This study scrutinizes the effect of each dimension of entrepreneurial orientation (i.e., innovativeness, risk‐taking, and proactiveness) and each of generic competitive strategies (i.e., differentiation and cost leadership) on the performance (financial and nonfinancial) of emerging SMEs. We surveyed 373 SMEs operating in Pakistan through a structured questionnaire. For the data analysis and hypotheses testing, we used AMOS.21. The findings display that innovativeness, proactiveness, and risk‐taking significantly improve financial performance while insignificantly impact nonfinancial performance. Differentiation and cost leadership strategies significantly spur financial as well as nonfinancial performance of SMEs. This study advises that top managers of SMEs in the emerging economies need to maintain a focus on entrepreneurial activities and formulate unique competitive strategies to attain higher performance. This research further recommends policymakers to initiate entrepreneurship programs for SMEs to configure entrepreneurial posture of the businessmen. Further recommendations have stated.     

The role of behavioral economics and behavioral decision making in Americans' retirement savings decisions

Traditional economic theory posits that people make decisions by maximizing a utility function in which all of the relevant constraints and preferences are included and weighed appropriately. Behavioral economists and decision-making researchers, however, are interested in how people make decisions in the face of incomplete information, limited cognitive resources, and decision biases. Empirical findings in the areas of behavioral economics and judgment and decision making (JDM) demonstrate departures from the notion that man is economically rational, illustrating instead that people often act in ways that are economically suboptimal. This article outlines findings from the JDM and behavioral-economics literatures that highlight the many behavioral impediments to saving that individuals may encounter on their way to financial security. I discuss how behavioral and psychological issues, such as self-control, emotions, and choice architecture can help policymakers understand what factors, aside from purely economic ones, may affect individuals' savings behavior.     

Seizures of Clandestinely Produced Tablets in Santa Catarina,Brazil: The Increase in NPS from 2011 to 2017

Ecstasy is the name given to a large group of substances known as “club drugs” traded in the form of tablets, powder and liquid that present a varied composition, including mainly 3,4-methylenedioxymethamphetamine (MDMA) and analogous substances, in addition to the growing presence of new psychoactive substances. Based on this, clandestinely produced tablets (“ecstasy tablets”) seized by police in Santa Catarina in the period from 2011 to 2017 were analyzed. During the study period, 3472 seizures occurred, which resulted in total 498,443 tablets seized. Seventy nine substances were identified. In the year 2011, about 90% of the tablets contained MDMA. This number decreased to 66.6% in 2017. On the other hand, there was an increase in the number of tablets that mainly contained synthetic cathinones, as well as tryptamine and piperazine derivatives. Police seizures in the metropolitan region of Florianópolis and on the coast prevailed over the rest of the state.     

The folly of “aid for stabilisation”

Over the last two decades, billions in aid money has been spent in highly insecure regions of conflict affected states in the hope that aid would lead to less violence and more stability. A recent wave of academic work on the impact of aid on violence has now amassed convincing empirical evidence that this hope is futile. Aid injected in highly insecure regions, where violence is a reality and insurgents retain some capacities, will increase, not dampen violence. This essay first provides a summary of the findings of the recent empirical literature. It then demonstrates that two causal mechanisms – predation and sabotage – explain why aid in highly insecure settings will likely lead to less, not more, stability. The essay then exemplifies these two causal mechanisms, using original qualitative and quantitative data from Afghanistan. It ends with a discussion of the implications for donors engaged in countries affected by conflict.     

Do Job Corps performance measures track program impacts?

Since the 1993 Government Performance and Results Act, performance measurement systems based on short‐term program outcomes have been increasingly used to assess the effectiveness of federal programs. This paper examines the association between program performance measures and long‐term program impacts, using nine‐year follow‐up data from a recent large‐scale, national experimental evaluation of Job Corps, the nation's largest federal job training program for disadvantaged youths. Job Corps is an important test case because it uses a comprehensive performance system that is widely emulated. We find that impacts on key outcomes are not associated with measured center performance levels. Participants in higherperforming centers had better outcomes; however, the same pattern holds for comparable controls. Thus, the performance measurement system is not achieving the goal of ranking and rewarding centers on the basis of their ability to improve participant outcomes relative to what these outcomes would have been otherwise. © 2008 by the Association for Public Policy Analysis and Management.
