A list of 20 words was presented 4 times to 3 groups of Ss. After each presentation, Ss attempted to recall as many of the words as possible, in any order they wished. Two experimental groups then learned a second unrelated list for 6 such free-learning trials, while the third group (control) did not. One of the experimental groups had a changed environment for List-2 learning, while the other group was unchanged. Retention of both lists (MMFR) was tested either after List-2 learning or 24 hr. later. The control recalled List 1 better than the two experimental groups, which did not differ from each other. List-1 recall in the experimental groups did not change over time.

Many outcome variables in developmental psychopathology research are highly stable over time. In conventional longitudinal data analytic approaches such as multiple regression, controlling for prior levels of the outcome variable often yields little (if any) reliable variance in the dependent variable for putative predictors to explain. Three strategies for coping with this problem are described. One involves focusing on developmental periods of transition, in which the outcome of interest may be less stable. A second is to give careful consideration to the amount of time allowed to elapse between waves of data collection. The third is to consider trait-state-occasion models that partition the outcome variable into two dimensions: one entirely stable and trait-like, the other less stable and subject to occasion-specific fluctuations.

The difference between intent (dolus) and negligence (culpa) was rarely emphasized in codified medieval laws and regulations. When compared to the legal statements related to intent, negligence was mentioned even more rarely. However, there are some laws that distinguished between the two concepts in terms of some specific crimes, such as arson. This paper draws attention to three medieval Slavic legal documents – the Zakon Sudnyj LJudem (ZSLJ), the Vinodol Law and the Statute of Senj. They are compared with reference to regulations regarding arson, with the focus being on arson as a crime committed intentionally or out of negligence. The ZSLJ as the oldest known Slavic law in the world shows some similarities with other medieval Slavic legal codes, especially in the field of criminal law, since most of the ZSLJ’s articles are related to criminal law. On the other hand, the Vinodol Law is the oldest preserved Croatian law and it is among the oldest Slavic codes in the world. It was written in 1288 in the Croatian Glagolitic script and in the Croatian Chakavian dialect. The third document – the Statute of Senj – regulated legal matters in the Croatian littoral town of Senj. It was written in 1388 – exactly a century after the Vinodol Law was proclaimed. When comparing the Vinodol Law and the Statute of Senj with the Zakon Sudnyj LJudem, there are clear differences and similarities, particularly in the field of criminal law. Within the framework of criminal offenses, the act of arson is important for making a distinction between intent and negligence. While the ZSLJ regulates different levels of guilt, the Vinodol Law makes no difference between dolus and culpa. On the other hand, the Statute of Senj strictly refers to negligence as a punishable crime. Even though the ZSLJ is almost half a millennium older than the Statute of Senj and around 400 years older than the Vinodol Law, this paper proves that the ZSLJ defines the guilt and the punishment for arson much better than the other two laws.

In this research, the influence of amino- and hydroxyethyl imidazolines of petroleum acids on the antistatic property and lubricity of diesel fuel has been studied. The researches illustrated that when the boiling point of petroleum acid fractions increases, the influence of imidazolines on the antistatic property and lubricity of diesel fuel decreases. Besides, it has been known that, the influence of aminoethyl imidazolines of petroleum acids on the antistatic property and lubricity of diesel fuel is better than the influence of hydroxyethyl imidazolines, On the other hand, it has been revealed that, when imidazolines of petroleum acids are added to the diesel fuel, the antistatic effect increases over time.

Objective: To illustrate the differential effects of D2- and D4-blocking neuroleptics on the procedural learning of patients with schizophrenia. Method: Twenty-nine schizophrenic patients were divided into 3 groups according to their pharmacological treatment: 1) drug naive, 2) haloperidol, and 3) clozapine. They were all assessed on clinical and procedural measures, the latter being the mirror drawing task. Results: All groups showed progressive learning over the successive trials, and drug-naive patients performed better than the other groups. Patients in the haloperidol group showed many fluctuations over trials, suggesting difficulty in the progressive automation of the task. Such fluctuations did not occur in the clozapine group, but performances per se were worse than in the other groups during the learning trials. A utomation of the task occurred at the same point (second block of trials) for all groups. Conclusion: These results suggest that D2- and D4-blocking neuroleptics do not similarly affect striatal dependent procedural learning in schizophrenia.

“Far, far away from our areas, somewhere beyond the Mountains of Darkness, on the other side of the Sambatyon River…there lives a nation known as the Red Jews.” The Red Jews are best known from classic Yiddish writing, most notably from Mendele'sKitser masoes Binyomin hashlishi(The Brief Travels of Benjamin the Third). This novel, first published in 1878, represents the initial appearance of the Red Jews in modern Yiddish literature. This comical travelogue describes the adventures of Benjamin, who sets off in search of the legendary Red Jews. But who are these Red Jews or, in Yiddish,di royte yidelekh? The term denotes the Ten Lost Tribes of Israel, the ten tribes that in biblical times had composed the Northern Kingdom of Israel until they were exiled by the Assyrians in the eighth century BCE. Over time, the myth of their return emerged, and they were said to live in an uncharted location beyond the mysterious Sambatyon River, where they would remain until the Messiah's arrival at the end of time, when they would rejoin the rest of the Jewish people.

We consider an agent that must choose repeatedly among several actions. Each action has a certain probability of giving the agent an energy reward, and costs may be associated with switching between actions. The agent does not know which action has the highest reward probability, and the probabilities change randomly over time. We study two learning rules that have been widely used to model decision-making processes in animals—one deterministic and the other stochastic. In particular, we examine the influence of the rules' ‘learning rate’ on the agent's energy gain. We compare the performance of each rule with the best performance attainable when the agent has either full knowledge or no knowledge of the environment. Over relatively short periods of time, both rules are successful in enabling agents to exploit their environment. Moreover, under a range of effective learning rates, both rules are equivalent, and can be expressed by a third rule that requires the agent to select the action for which the current run of unsuccessful trials is shortest. However, the performance of both rules is relatively poor over longer periods of time, and under most circumstances no better than the performance an agent could achieve without knowledge of the environment. We propose a simple extension to the original rules that enables agents to learn about and effectively exploit a changing environment for an unlimited period of time.

In this article, the influence of the European Union’s (EU) Green Deal on its energy relations with Russia is analyzed. Two models of resilience are identified in the EU’s discourse. One aims at achieving resilience at the level of the EU’s energy sector (the “microsystem” for the purpose of this study) while destroying the system of EU-Russia relations (the “macrosystem”). The other aims at achieving resilience in the micro- and macrosystem at the same time. Empirically, the study relies on EU documents and speeches by its national and supranational representatives. Three cases are studied. The first covers competition of two models of resilience in the principles that the EU defined for its relations with Russia. The second case involves investments that slow down the development of renewable sources of energy in favour of natural gas. This case demonstrates how resilience can be achieved as a return to the previous pattern (bouncing back). Although it can be achieved both at the EU-only level and at the level of the EU and its relations with Russia, it clearly favours the latter. The third case involves the import of hydrogen, which creates possibilities for resilience both at the microsystem alone and at the micro- and macrosystems at the same time. This latter option is achieved through adaptation to new challenges (bouncing forward). The author concludes by comparing the two models of resilience. The model that prioritizes the microsystem’s resilience and challenges the macrosystem is based on the synthesis of environmental and geopolitical logics. The other model is based on economic and market logics, but the EU’s normative leadership is a prerequisite. The EU’s discourse demonstrates the viability of both models and related governance practices. Most likely, the two models will co-exist, but their relative importance will vary over time. This variation will be primarily determined by the EU’s internal constraints. However, Russia’s policy can facilitate the model of resilience, achieved in both the micro- and macrosystem.

An avid reader of history will be quite familiar with the rich, emotive narratives detailing the tragic decline and ultimate fall of once mighty civilizations; Rome succumbing to barbarian hordes, Alexander of Macedon’s and Chinggis Khan’s spear-won empires splitting into warring factions, and the demise of the great Inca or Maya civilizations are just a few such examples. On the other side of the stacks, similarly grandiose narratives document some group’s incredible growth and spread taking over vast territories and populations. These tell typically of societies coming to dominate a region, often in the face of overwhelming odds and tribulation or through some precocious development of a key technology or strategy that later becomes widespread. Here, I take stock of previous approaches to studying function – from growth and development to crisis and collapse to resilience – and ask what is the most fruitful lens with which to view fluctuations in how societies function and change over time, as this review essay attempts to accomplish.

Abstract The suitability of 3 methods for determining aflatoxins in melon seeds was examined. The first 2 are the Contaminants Branch (CB) method and the Best Foods (BF) method, both official methods for determining aflatoxins in peanuts and peanut products. The third method, the modified CB method–Rapid Modification of the Cottonseed (CB-RCSMod) method, devised in this work, was derived by combining steps from the CB method and the Rapid Modification of the Cottonseed method. The CB method was superior to the other 2 methods for quantitation of aflatoxins. It gave better recoveries and cleaner extracts that exhibit less fluorescent interference for thin-layer chromatography (TLC) than the BF method. Also, its solvent efficiency was better than that of the CB-RCS-Mod method. With the CB method, recoveries from spiked samples were 85.0% for aflatoxin B1 and 90.0% for anatoxin B2. Recoveries of G1 aflatoxins were more variable, averaging 90.0% for aflatoxin d and 72.5% for aflatoxin G2. Total aflatoxin recovery was 86.5% for the CB method. At a low aflatoxin contamination level (8 μg B1/kg sample), aflatoxin B1 was detectable by the CB method but not by the BF method. Detection of aflatoxins in BF method sample extracts by TLC was not improved by the use of chloroform–acetone–water (88 + 12 + 1), benzene–ethanol–water, or ether–methanol–water (96 + 3 +1) in place of the standard chloroform–acetone (88 + 12) developer. Use of ether–methanol–water (96 + 3 + 1) for detecting aflatoxins by TLC in the CB method extracts increased interference compared with the standard chloroform–acetone (88 + 12) developer.
