This is a book review of the volume edited by Roberta Piazza and Alessandra Fasulo, and entitled Marked Identities. Narrative Lives Between Social Labels and Individual Biographies, Palgrave Macmillan, London-New York, 2015. The book consists of various interviews with individuals whose lives, mainly because of the group to which they belong, could be viewed as ‘marked’. The difference between the idea of ‘stigma’ and the notion ‘marked identity’ is underlined, together with the idea of ‘diversity’, which today is not necessarily something that one should hide but, quite the opposite, something one can be proud of. One of the main ideas of this text is that identity is not a rigid reality but a process, by which individuals negotiate the version of who they are with others.

Due to its character of totalitarian regime and through the major changes imposed in the society, the communist regime in Romania between 1945 and 1989 represents a distinct period in the history of the country. A series of inflicted macrosocial processes, such as the strictly centralized economy, collectivization and nationalization, as well as some phenomena such as the control of citizens’ lives, the impossibility of free expression, censorship of the press and culture, the lack of consumer goods, restrictions on utilities, and so on, negatively marked the fate of many Romanians during this period. However, many people remember this period with nostalgia. The present paper deals with the popular culture in Romania during the communist period (1945–1989), as seen, considered, and remembered by people who lived in that era, or at least in a period of it. The research was based on the method of life histories and focussed on the viewings of the subjects regarding the practices, rituals, artefacts, and products of popular culture in the communist time. Both folk culture and mass culture are discussed and analysed, as well as the elements of lifestyle, as described by the subjects. Moreover, the influences on the popular culture in that period are outlined, such as those of some large-scale phenomena like industrialisation and urbanisation, Western trends, Soviet propaganda, or the different impositions of the Romanian authorities, according to the various stages the communist regime has been going through in this period. The gathered data show that, while many memories of people are sorrowful and bitter, other recalls and considerations regarding the cultural practices of that time, and especially the human relations built by the means of these practices, are full of nostalgia. These aspects concerning popular culture in a particular historical period and nostalgia related to it are discussed in detail in the paper.

Almost 'since ever' ecologists have made attempts at the generalization of various site-specific, species-specific and time-specific situations, including different classifications of species, based on different principles and prepared for different purposes. This paper, presenting a conceptual model for selecting species of similar life-history pattern to other species and providing an example using birds as a model system, represents that current in the ecology. Ali bird species regarded as nesting in a given area of the mosaic landscape in southern Poland were described with respect to nine variables (nest type, nest location, food habits, place and way of foraging, migration status, number of broods, clutch size, incubation and fledging periods), grouped into 43 categories. Cluster analysis was then used to distinguish objectively species displaying similar life history traits and environmental adaptations into unique life-history 'strategies'. The results of an exemplary analysis of variability in the density, domination, number of species and turnover rate in particular strategies, depending on the size of study plots, their structure, degree of isolation and the characteristic features of their surroundings, using regression and canonical correlation techniques, indicate the suitability of this approach to testing detailed hypotheses connected e.g. with studies on the response of species to different habitat conditions. The methods applied allow one to distinguish, in an objective way, the groups of species displaying similarities with respect to life history traits and environmental adaptations, in spite of the fact that the method of describing variables in cluster analysis may determine a different allocation of species to groups. A model, as described, could allow conservation principles to be developed for species of similar distribution, ecological feature or life history; especially for those species which face with population declines and for which no previous patterns have been established.

Despite the growing number of statistical analyses of life-history data and a long tradition of biographical research, there is often no communication between these two streams of life-course research. It is possible to examine the life course quantitatively through life histories, which may be used to model synthetic biographies in order to reveal patterns in the timing and sequencing of life events, the durations of states between them, and the causal links between them. It is also possible to examine the life course qualitatively through life stories, e.g. biographical narratives, which reflect how persons understand, experience and attach meaning to events and states in their life. Through a quantitative analysis of life-history data we can describe and explain the morphology of particular events in the observed population, while a qualitative analysis of biographical narratives provides insight into people’s decision-making, perceptions of their options, and how they attach meanings to and experience events. This article summarizes the strengths and weaknesses of both approaches, explains in which sense they are connected or differentiated from each other, what data and analyses each perspective may utilize, and briefly introduces one type of mixed methods life course research that utilizes the complementarity of both approaches.

A study of two 100-person groups of juvenile delinquents born in 1959 was conducted in the years 1981‒1985 at the Department of Criminology, Institute of Legal Studies, Polish Academy of Sciences. The first (experimental) group consisted of boys randomly selected from the total of 225 juveniles born in 1959 who had committed at least on offence while intoxicated. The other (control) group were 100 randomly juveniles selected from the entire population of 8196 juvenile delinquents born in 1959. None of the juveniles selected for the experimental group happened to find themselves in the control group as well. As shown by the findings, the juveniles who had committed at least one offence while intoxicated were much more demoralized as a group than the whole of juvenile delinquents. It seemed interesting, therefore, to follow the further fates of both groups as adults. The follow-up period was 7 years; until that time, all of the examined persons reached the age of 25 when the average Polish man be- comes stabilized to some extent, having graduated from university, worked for several or a dozen years (upon completion of secondary or elementary education respectively), and frequently having also established a family.  Data on the life situation of the young men from both examined groups on their 25th birthday were obtained from the following four sources: ‒ the Central Register of Convicted Persons kept  by the Ministry of Justice, and the Register of Convicted and Detained Persons where criminal records of the entire sample were checked; ‒ files of criminal cases of all men with criminal records (47.0% of the experimental and 35.0% of the control group); the files concerned criminal proceedings before common courts for offences committed after coming of age; ‒ questionnaire survey of 63.0% of the experimental and 66.0% of the control group; ‒ inquiry submitted to the sobering-up stations concerning the entire sample. As shown by the findings, 24.0% of the experimental and 13.0% of the control group established their own families before the age of 25. The proportions are high, as regards the experimental group in particular: erly in the 1980s, the newly married constituted about 10% of the total male population aged 20‒24 in Poland. The mean educational level was higher in the control compared to the experimental group; this concerns first  and foremost  cases of education higher than the elmementary technical (of which there were two in the experimental compared to ten in the control group). Moreover, no cases of illiteracy could be found in the control group, compared to one such case in the experimental group. Of all the men of the experimental group concerning whom data could be obtained, 80.4% had a regular job, and 19.6% stayed out of job or worked casually. Of the control group, 80.0% had a regular job (33% combining job with school), 18.3% stayed out of job or worked casually, and one person had entered university. The number of convicted persons in the experimental group (47) was larger compared to the control group (35) by 12.0%, the difference being significant. Also relapse into crime was higher in the expenmental group (l5 vs. 11 cases). The first offence committed by those convicted as young adults was mainly one against property: 35 cases in the experimental group (66.0% of all those convicted) and 28 cases in the control group (80.0%). The second most frequent offence of members of the experimental group was an aggressive act: against life and health, freedom, personal dignity and inviolability (10 persons, i.e. 18.8% of all those convicted). The offences of this type included: bodily injury (Art. 156 of the penal code – 3 persons, i.e. 6.4%); participation in a brawl or beating (Art. 158 and 159 – 1 person, i.e. 2.1%); infringement of bodily inviolability (Art. 182 – 3 persons, i.e. 6.4%); assault against a public functionary (Art. 233 and 234 – 1 person, i.e. 2.1%); insult against  a public functionary (Art. 236 – 1 person, i.e. 2.1%). In the control group, 6 cases of such offences could be found (9.1% of all those convicted);  yet the only offence under Art. 148 1 of the penal code, that is homicide, had been committed by a member of that goup.The other discussed figures and proportions were respectively: Art. l58, 159 – 3 persons, i.e. 8.6%; Art. 182 – 1 person (2.9%); Art. 233, 234 – 1 person (2.9%); and Art. 236 – 1   person (29%). Beside offences, the two groups manifested also other synptoms of social maladjustment. The symptoms found most often in both groups were: “contacts with persons known to the police as delinquent” and stays at the sobering-up station. As regards the experimental group, the third frequent symptom were brawls in the place of residence followed by bad opinion with neighbors, hooliganism, and avoidance of work. In the control group, avoidance of work ranked third, followed by bad opinion with neighbors, hooliganism, and brawls at the place of residence. This ranking of frequency of the symptoms of social maladjustment points to a greater aggressiveness of the young men from the experimental group. On the 63 young men from the experimental group concerning whom data  could be obtained, 62 (98.0%) drank alcohol. In the control group 59 (89.0%) of the 66 concerning whom data could be obtained were drinkers. The group of drinkers included all those who had drunk several times a week already  as juveniles, and 70% of those who had drunk once a week. In the control group, drinkers included 91.7% of those who had drunk as juvoniles (11 of 12 cases). Of those who had drunk as juveniles in the control group, 66.7% (8 cases) were convicted as adults. As shown by the discussed data, young men from the experimental group – those who committed as juveniles at least one offence while intoxicated prove much inferior in terms of the social situation  to other men who also committed offences as juveniles but did not drink alcohol. Therefore, early alcohol consumption among juvenile delinquents is an important factor of a negative prognosis as to the further fates of such persons. A number of postulates have been formulated, addressed at the prosecuting agencies, criminal justice, and institutions designed to assist persons in extraordinary situation. With respect to the present sample, all such postulates acquire special importance and must be met without fail.

In the past 30 years, Daphnia has become a model organism in aquatic ecology. I review the changing concepts and paradigms in plankton ecology as reflected in the work on Daphnia. The availability of radiotracers favoured a new physiological approach that resulted in better energetic models and more reliable estimates of filtering rates. This led to deeper insights into the role of herbivore grazing on phytoplankton and microbial communities, and nutrient recycling. It provided a conceptual basis for general hypotheses on predictable seasonal successions (e.g. the PEG model). On the other hand, increasing knowledge about selective predation on zooplankton triggered population dynamic models and gave explanations for changing community structures. The Size-Efficiency-Hypothesis generated a framework for studies on trade-offs between competitive ability and susceptibility to predation. Daphnia was now in the centre of interaction-based concepts, being predator and prey at the same time. It was the backbone of practical applications of the theory in food-web manipulations. When ultimate factors came into the focus, Daphnia played an important role in explaining striking phenomena like diel vertical migration and cyclomorphosis. Its central position in food-webs, the unique propagation mode, easy cultivation and accessibility by molecular genetic methods made it a favourite object for studies in evolutionary ecology, concerning local adaptation, evolution of defences and life histories, induced phenotypic change, and genetic diversity. The large advantage of Daphnia over other biological model organisms is that its importance in pelagic freshwater systems is undoubtedly known. Hence there is a direct way of applying the results to ecological systems.
