Education and development; females’ education and fertility reduction in Africa: The case of Tigray,Ethiopia

The livelihood of the population in general, and females in particular, is affected by different socio-economic, demographic, environmental, cultural and other factors. the three main demographic variables: fertility, mortality and migration, which are also functions of some other variables, determine the quality of women’s lives. Some of the variables that are expected to determine the levels of fertility, mortality and migration may include literacy status, educational level, occupation, income, place of residence, marital status and other factors. Fertility is the most important variable in the population dynamics. A study was made in tigray, ethiopia, that included 2290 individuals. Of these, 1371 (60%) were females. the method of enumeration was used in order to collect the necessary information from the target population. the age structure, household composition, place of residence, educational level and other background variables were analysed. Results show that the literacy status and educational level were important variables that determined the age at first marriage, the use of family planning services, and antenatal and postnatal care. thus, it was concluded that female education is a key variable that enhances the participation of women in the development process by improving their status through the reduction of fertility.     

Police Manipulations of Crime Reporting: Insiders’ Revelations

Social scientists have theorized about the corruption of crime reports (Bayley, 1983; Campbell, 1976). Yet, scant empirical research has examined the impact of modern policing methods on the accuracy of crime reporting. Our research uses an anonymous survey of 1,770 retired New York City police officers examining retirees’ experiences with crime report manipulations across their years of retirement. This includes retirees from the community policing as well as police performance management eras. We subject the data to various statistical tests including tabular analysis, graphical trends to visualize the data, MANOVA, and logistic regression to explain report manipulations. Results indicate that the misuse of the performance management system and pressures on officers from management are key explanations for manipulating crime reports. Individual explanatory variables such as gender, educational status, rank, race, and marital status had no effect. Our research supports Bayley’s and Campbell’s theories. We recommend greater transparency to remedy this.     

Explaining interest group access to parliamentary committees

This article explains why parliamentary groups invite interest groups to the parliamentary arena. It argues that interest groups’ access to committees not only reflects policy-makers’ need for information and expertise but also party preferences and institutional factors such as the type of government, parliamentary committee structure and committee agenda capacity. Results show that interest groups’ access to the parliamentary arena increases under minority governments, in the case of highly conflictual issues, and when the number of permanent committees increases. Also, results demonstrate that parliamentary groups invite interest organisations following different logics – problem-solving or confrontation logic – depending on the type of functions they have to perform – legislative and oversight activities. The article uses a novel, comprehensive database with information on the appearances of all interest groups in the Spanish parliament from 1996 to 2015.     

Skunks in an English Woodland: Should England Embrace For‐Profit Higher Education?

The British government is encouraging the growth of for‐profit alternative providers of higher education (HE). While it is true that for‐profits have opened HE access to previously under‐served groups and have been more agile in reacting to market demand, they have done so at a considerable cost to students and the taxpayer because they do not share in the cost of the failure of HE to ensure a payoff for many of their students. The US experience with for‐profits should be a cautionary tale for those supporting their expansion in Britain. Policy is needed to craft a regulatory framework that produces the benefits that for‐profits can provide, but minimises the costs that often accompany them. At present, it is far from clear that expanding alternative providers—that is, for‐profits—would ‘work better’ for students.     

Effects of cocaine and heroin,and their combination,on the development rate of Calliphora vomitoria (Diptera: Calliphoridae)

Insects present on or near decomposing bodies are collected by forensic entomologists and used to estimate the post-mortem interval. Drugs metabolized by a person before death may affect the rate of development of insects feeding on the corpse. This study aimed to determine the effects of cocaine and heroin main metabolites on the development rate of the Calliphora vomitoria (Diptera: Calliphoridae) and their implications on minimum post-mortem interval determination. Groups of 250 eggs each were placed into four separate pots of 150 g of minced pork meat being either un-spiked, or spiked with benzoylecgonine, morphine, or a combination of both. Larval length (mm) and weight (mg) measurements were taken twice daily and the rate of development of the insects’ life cycle was monitored until eclosion. Results show that cocaine-fed larvae developed less in length and weight than the control group. Heroin-fed larvae showed a more fluctuating pattern, being smaller and lighter than the control group for most of their larval cycle, but overtaking them in both parameters towards pupation. Combination-fed larvae seemed to favour the effects of cocaine. The three conditions also had a significant impact on the length of the insects’ life cycle. Cocaine and drug combination treatments increased the length of the second and third instar stages, but led to the shortening of pupation and accelerated eclosion. Conversely, heroin treatment led to lengthier pupation. Interestingly, the effects of the drug combination seemed to mirror more precisely those of cocaine.These findings indicate that both cocaine and heroin, singularly and in combination, have sizable effects on blowflies’ development rates, potentially biasing post-mortem interval estimations.     

How frequently are Autosomal and X-STRs multistep mutations perceived as single-step?

Short tandem repeats (STRs) incur in length mutations that involve the loss or gain of repeats. STR mutation rates are usually estimated considering the rates of observed Mendelian incompatibilities in one generation familial configurations. When considering multistep mutations, for the autosomal and X-chromosomal modes of genetic transmission, underestimations are inevitable when using this approach (MIA), due to the occurrence of mutational events deceptively perceived as involving fewer steps. The rate of this occurrence depends on the mode of genetic transmission considered, the parental origin of the mutation, the type of familial configuration considered, and the genotypic background of the progenitor(s). MIA biases were weighted and compared for the diploid and haplodiploid modes of transmission, using familial genotypic configurations (parent(s)-child duos and trios) generated resorting to Python™ and real population databases from Norway, Somalia, and Spain for 10 Aut-STRs and Argentina, Eastern Asia, and Northern Europe for 12 X-STRs. One two- or one three-step mutation was simulated in each of the 1,000,000 familial configurations. The frequency with which mutations could be interpreted as involving fewer steps, when the most parsimonious reasoning is employed, was computed. Results showed that the magnitude and type of biases depend on the type of familial data and the genetic mode of transmission considered, being higher in duos than in trios, both in autosomes and the X chromosome. Indeed, whether X- or Aut-STRs are analyzed, trios generally provide better estimates and should be favored over duos. The pooling of the two types of data is not advised. The greater the number of steps involved in the mutation, the worst the estimates obtained. In X-chromosomal analyzes, trios with a paternal mutation presented the best estimates and mother-daughter duos the worst; mother-son duos showed similar estimates to trios when a maternal mutation was considered.     

犯罪着手的教义学重述:学说对决、命题重证与具体解答

形式客观说并未丢弃实质,故其本为形式与实质相结合说。是否立足于构成要件行为是法益侵害紧迫危险性的刑法定型,决定了形式客观说和实质客观说各自是否为犯罪着手认定提供了明确标准,且是否导致犯罪着手认定的过于提前或推迟,进而决定了是否背离罪刑法定原则。犯罪着手的认定标准,应抛弃脱离形式限制的实质客观说而仍坚持形式客观说,但其“开始命题”应通过“基于大数法则的类型化危险形成说”而将犯罪着手的认定标准予以实质性落实。通过“基于大数法则的类型化危险形成说”,形式客观说对结合犯、隔离犯、徐行犯和原因自由行为型犯罪的着手能够做出妥当解答。     

知识产权法"利益平衡说"之反思:自然法与功利主义之比较

“利益平衡说”被认为是知识产权法之基本原则或基本精神,旨在平衡权利人个人利益与社会公共利益之冲突,并以此解释知识产权法的制度构成。依自然法理论,知识产权之正当性因其自然获得性,相关权利与限制是确定权利的正当边界,维护以个人权利为基础之社会契约。功利主义理论则认为知识产权保护是实现社会效用之必要工具,经由排他性权利及其限制来达至社会效用最大化。无论限制或保护权利均有可能产生对权利或社会效用的正面或负面作用。由此,利益平衡的二元价值目标论值得商榷。知识产权法的根本问题是以个人权利为导向还是以社会效用为终极价值之选择问题。     

Investment sensitivity to interest rates in an uncertain context: is a positive relationship possible?

This paper shows a non-linear relationship between investment and interest rates under uncertainty. Since the interest rate’s variance is positively related to the investment’s value (through the discount factor) and, generally, is also positively related to the interest rate’s level, then, at the same time, a negative (classical) and a positive (through the interest rate’s variance) relationship links interest rates to investment. Hence, an ultimate and even positive relationship between investment and interest rates’ (expected) level may occur. A specific model is proposed and the conditions upon which the positive effect occurs are derived. Some estimates are also proposed.

Cumulative impact: Why prison sentences have increased*

Why has the probability of going to prison after a felony conviction increased since the early 1980s? Social scientists often try to answer this question through macro‐level research that is aimed at examining correlations between prison admissions and crime rates or sociopolitical characteristics of states. That type of macro‐level inquiry, however, does not allow for a close examination of how characteristics of offenders changed over time, and whether such changes are consequential for understanding trends in the use of imprisonment. In the current study, I take a different approach—one in which case‐level data are observed over a lengthy time span—to investigate why the likelihood of going to prison for a given crime persistently increased for several decades. The results of analyses of more than 350,000 felony cases sentenced in Minnesota during a 33‐year period show that the probability of a defendant receiving a prison sentence increased from 1981 to 2013, as would be expected. The primary reason for the rising probability of imprisonment was the significant increase in the average offender's criminal record, which more than doubled during the observation period.
