In this paper, we examine how SMEs successfully implement proactive social and environmental strategies (PSEs). Using inductive theory building on 8 case studies of small and medium enterprises (SMEs) operating in both developing and developed country contexts, we identify four dynamic capabilities that explain how SMEs overcome time, resources, knowledge, and power constraints when implementing proactive social and environmental strategies. We introduce three moderating variables to explain how level of country development, organizational lifecycle, and availability of supporting institutions could (...) impact the level of capability importance. Furthermore, we discuss the interconnectedness of these capabilities to fully explore their dynamism in explaining how SMEs engage in sustainable business practices. (shrink)

The impact of smaller firm size on corporate social responsibility (CSR) is ambiguous. Some contend that small businesses are socially responsible by nature, while others argue that a smaller firm size imposes barriers on small firms that constrain their ability to take responsible action. This paper critically analyses recent theoretical and empirical contributions on the size–social responsibility relationship among small businesses. More specifically, it reviews the impact of firm size on four antecedents of business behaviour: issue characteristics, (...) personal characteristics, organizational characteristics and context characteristics. It concludes that the small business context does impose barriers on social responsibility taking, but that the impact of the smaller firm size on social responsibility should be nuanced depending on a number of conditions. From a critical analysis of these conditions, opportunities for small businesses and their constituents to overcome the constraining barriers are suggested. (shrink)

This paper is devoted to theoretical and methodical considerations on our study and understanding of macroscopic transitions in the world of Sanskrit intellectuals from the sixteenth to the eighteenth century (cf. Pollock, Indian Economic and Social History Review 38(1):3–31, 2001). It is argued that compared to his immediate predecessors Bhaṭṭoji Dīkṣita’s contribution to Prakriyā grammars was modest. It was to a large extent on account of changed circumstances—over the centuries mainly a slow but steady decline—in the position of Sanskrit and (...) the general public’s need for a simple definition of authoritatively correct Sanskrit that Bhaṭṭoji’s grammar met with success so quickly, so widely, and so solidly. I once knew a little boy in England who asked his father, “Do fathers always know more than sons?” and the father said “Yes.” The next question was, “Daddy, who invented the steam engine?” and the father said “James Watt.” And then the son came back with “But why didn’t James Watt’s father invent it?” Gregory Bateson (1972, p. 21).

1. Cabinet made small effort to start consultations between the communities.It left the initiative to the political parties and to Flemish employers.2. The president of the VEV played an active role bebind the curtains. He mediated between certain Flemish and W alloon political circles. He tried to get the Volksunie info the cabinet. He found himself sadly out in his reckoning on the Walloon side, because he overlooked the strong socialist opposition.3. The opposition Socialist Party overcame the deadlock by (...) publishing a plan for the definitive state-reforms. Flemish, Walloon and Brussels socialists agreed to this plan. It became the beginning of negotiations between the communities, which started on November 30.4. The negotiations are difficult, mostly because the Walloons have no unified view on state-reforms.

Considerable experience as a teacher of ethics and an observer of human interaction on a small and a large scale has convinced me of an important truth. Our capacity to make good and just choices is limited by our chaotic moral and emotional lives. It is not as if our culture lacks the intellectual resources to address this problem. They have been available in outline at least since classical Greek antiquity. This article is an attempt to convey some of (...) those important ideas at a basic or introductory level. (shrink)

In the Vietnam war, Lieutenant Calley, claiming to be following orders, ordered the killing of several hundred women, children, and elderly people in the village of My Lai. In 1969, Lieutenant (later Senator) Kerrey led a small group of SEALs in the dead of night on a dangerous military venture. In course, a dozen or so innocent villagers were either shot in crossfire or killed intentionally because there seemed a real chance that they would inform the enemy, endangering themselves (...) and the mission. I argue that Calley was clearly not justified and that Kerrey, given the circumstances, may have been. More generally, I argue that all soldiers at all ranks must be expected to act decently, with as much regard to the distinction of civilian/combatant as circumstances permit. That one is following superiors’ orders is never sufficient, of itself, to justify what would otherwise be grossly evil acts. (shrink)

Political relations in today’s world are in a deep, perhaps even radically threatening disequilibrium; similarly, humanity’s home—the Earth—is treated with disdain and contempt despite its increasingly angry protests. Moreover, the rules and principles by which most of the world runs its economic affairs and strives to “modernize” its life are founded on a set of market laws devoid of all social context and only serve to deepen the dangerous contrasts between small islands of wealth and a sea of humanity (...) doomed to poverty and alienation.

Between Calculability and Non-Calculability. Issues of Calculability and Predictability in the Physics of Complex Systems. The ability to predict has been a very important qualifier of what constitutes scientific knowledge, ever since the successes of Babylonian and Greek astronomy. More recent is the general appreciation of the fact that in the presence of deterministic chaos, predictability is severely limited (the so-called ‘butterfly effect’): Nearby trajectories diverge during time evolution; small errors typically grow exponentially with time. The system obeys deterministic (...) laws and still is unpredictable, seemingly a paradox for the traditional viewpoint of Laplacian determinisms. With the concept of deterministic chaos the epistemological issue about an adequate understanding of predictability is no longer just a mere philosophical topic. Physicists on the one hand recognize the limits of (long term) predictability, computability and even of scientific knowledge, on the other hand they work on concepts for extending the horizon of predictability. It is shown in this paper that physics of complex systems is useful to clarify the jungle of different meanings of the terms ‘predictability’ and ‘computability’ — also with philosophical implications for understanding science and nature. Today, from the physical point of view, the relevance of the concepts of predictability seems to be underestimated by philosophers as a mere methodological topic. In the paper I analyse the importance of predictability and computability in physics of complex systems. I show a way how to cope with problems of unpredictability and noncomputability. Nine different concepts of predictability and computability (i.e. open solution, sensitivity/chaos, redundancy/chance) are presented, compared and evaluated. (shrink)

This article discusses some aspects of developments in the Czech Republic during the 15 years since the downfall of the Communist regime. At the level of social structures, the dominant trend has been a rapid growth of inequality, which has blocked the development of a middle-class society. At the political level, the most salient tendency is the growth of a 'silent majority', not least due to the murky methods of privatization and the manifest corruption among the new elite. The problems (...) of the ecological movement exemplify the difficulties faced by nascent civil societies in post-Communist conditions. Finally, the author tries to identify likely trends linked to the dynamic of globalization. Here the most serious problem is the stagnation or even decline of the employees and small entrepreneurs who were once expected to become the backbone of civil society. (shrink)

Gerold Tietz was born in 1941 in Horka (north Bohemia) in a family of Sudeten Germans. Germans lived in this village together with Czechs, Roma people and Jews. The family also involved Czech relatives and many of German relatives spoke good Czech and kept relations with Czech cultural groups. After the war Gerold Tietz and his family were expelled to Swabia. He studied history, French and political science. From 1969 the graduated historian lived in Esslingen where he taught in the (...) grammar school for thirty years. In the autobiographically oriented novels _Böhmische Fuge _(1997), _Böhmisches Richtfest _(2007) and in _Böhmische Grätschen _(2009) Tietz tried to depict official social-political events connected with famous political and cultural figures as well as the stories of ordinary days of “small people” who had to face the consequences of historic changes which influenced their lives. The paper analyses the conditions of Czech and German coexistence and confronts the authentic historic context. Nevertheless, negative features of these ethnic groups are not overlooked and the positive ones are presented as a positive contribution to the current European multiculturalism. (shrink)

This paper describes the common techniques used in the constitution of candidates-lists for parliamentary elections. A common feature of these techniques is the consultation of party members. But the way in which this is done differs among the parties. AGALEV, the ecologist party, offers every member the possibility to have his say about every candidate. The socialist party uses this system in two constituencies ; in the other constituencies a special congress decides. The christiandemocrats, the liberals and the Flemish nationalists (...) constitute their lists by indirect vote : the leadership performs a first selection and the members then either approve or disapprove of this choice.Our research indicates that there are no essential differences between these two techniques from the point of view of membership participation.In both the ecologist and the socialist party the majority of members does not participate in the candidates-elections. Therefore, as with the indirect vote, candidates-lists are constituted by an active, militant and elitist group of members. Whatever the technique used the infl,uence of the rank-and-file-member is small. (shrink)

This book maps the entire development of Comenius’s considerations on man, from his earliest writings to his philosophical masterwork. Although this book primarily offers an analysis and description of the conception of man in Comenius’s work, it may also serve the reader as a more general introduction to his philosophical conception. The author shows that, in spite of the fact that Comenius has received no small amount of academic attention, funded studies or monographs in English language remain in single (...) figures. Thus, a range of Comenius’s remarkable ideas are still unknown to the wider public. (shrink)

The feasible interpolation theorem for semantic derivations from [J. Krajíček, Interpolation theorems, lower bounds for proof systems, and independence results for bounded arithmetic, J. Symbolic Logic 62 457–486] allows to derive from some short semantic derivations of the disjointness of two [Formula: see text] sets [Formula: see text] and [Formula: see text] a small communication protocol computing the Karchmer–Wigderson multi-function [Formula: see text] associated with the sets, and such a protocol further yields a small circuit separating [Formula: see (...) text] from [Formula: see text]. When [Formula: see text] is closed upwards, the protocol computes the monotone Karchmer–Wigderson multi-function [Formula: see text] and the resulting circuit is monotone. Krajíček [Interpolation by a game, Math. Logic Quart. 44 450–458] extended the feasible interpolation theorem to a larger class of semantic derivations using the notion of a real communication complexity. In this paper, we generalize the method to a still larger class of semantic derivations by allowing randomized protocols. We also introduce an extension of the monotone circuit model, monotone circuits with a local oracle, that does correspond to communication protocols for [Formula: see text] making errors. The new randomized feasible interpolation thus shows that a short semantic derivation of the disjointness of [Formula: see text], [Formula: see text] closed upwards, yields a small randomized protocol for [Formula: see text] and hence a small monotone CLO separating the two sets. This research is motivated by the open problem to establish a lower bound for proof system [Formula: see text] operating with clauses formed by linear Boolean functions over [Formula: see text]. The new randomized feasible interpolation applies to this proof system and also to cutting planes CP, to small width resolution over CP of Krajíček [Discretely ordered modules as a first-order extension of the cutting planes proof system, J. Symbolic Logic 63 1582–1596] ) and to random resolution RR of Buss, Kolodziejczyk and Thapen [Fragments of approximate counting, J. Symbolic Logic 79 496–525]. The method does not yield yet lengths-of-proofs lower bounds; for this it is necessary to establish lower bounds for randomized protocols or for monotone CLOs. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:1. The present state of the questionEsser's turnaboutIn his collection of studies on the writings of Francis, published in 1973, Kajetan Esser, the acknowledged master of Franciscan textual criticism, wrote that in verse 13 of Francis's Letter to the Clergy there exists "a striking difference, that is difficult to explain," between the oldest manuscript which originally belonged to the Benedictine abbey of Subiaco and was written before 1238, and (...) the famous manuscript Assisi 338 which originated between 1250 and 1260. However, Esser considered this difference "a too weak basis to accept a double version of the Letter to the Clergy." It is therefore somewhat strange, to say the least, that in his textcritical edition of the writings of Francis, published only three years later in 1976, the same Esser concludes, without any further explanation, that the differences are "so serious that one has to accept two versions of one and the same letter."Esser's conclusion immediately raises the question about which one of the two versions would be the first. Esser opted for the Subiaco manuscript as the first version and the Assisi manuscript as the second. An important reason for Esser's option was the fact that the Assisi manuscript of the Letter to the Clergy added in verse 13 that the clerics have to observe all of these matters "according to the precepts of the Lord and the constitutions of holy mother Church ." With "the constitutions of holy mother Church" Francis referred, according to Esser, to the papal bull Sane cum olim, issued by pope Honorius III on November 22, 1219. And as this bull, in Esser's view, also "contained references to the will of God as laid down in Holy Scripture," Francis decided to insert both a reference to the papal bull and to "the precepts of the Lord" in a new, second version of the letter. This would imply that Francis, who in the summer of 1219 left for Egypt, wrote the second version only after his return from the Middle East in the spring of 1220. For it was only then that he came to know about the existence of the papal bull issued during his absence from Italy, and could refer to it in order to strengthen his appeal to the clergy to show greater reverence for the Eucharist. At the same time, however, the absence of these important additions in the first version implies that this version was written before the papal bull of Honorius was issued and thus also before Francis's departure for the Middle East in the summer of 1219.Present reception of Esser's theoryThe latest English translation, published in 1999, follows Esser and contains a separate translation of both versions, the first of which was written before 1219 and the second in 1220. In the most recent German translation Leonhard Lehmann acknowledges the existence of two versions but the differences between the two are so small that it suffices to print only the text of the oldest manuscript, that of Subiaco, written before 1238. He agrees, though, that the addition constitutiones sanctae matris Ecclesiae in the second version refers to the papal bull Sane cum olim and that the earlier version may have been written before 1219. The revised edition of the Fonti Francescane still follows Esser's theory as regards the existence of two versions, the early date of the first version and the reference of the second version to Sane cum olim. However, in a lengthy article on Francis's letters, C. Paolazzi, the author of the introduction to the Letters in FF, revised his previous opinion in 2008. He still accepts the existence of two versions but dates both after Sane cum olim and therewith also after Francis's return from the Middle East in 1220. His main argument is that theimplicit quotations.. (shrink)

The simple model of conflict-prone situations called Prisoner’s Dilemma is discussed. Whereas the best strategy for the model is to defect, in the case of its iterated version (Iterated Prisoner’s Dilemma—IPD) it is possible and more profitable to cooperate with the opponent.The simple strategy called Tit for Tat (TFT) which is easy to recognize, never defects first, punishes every defection but is also forgiving is presented. The TFT strategy is very successful being able to establish the cooperation with its opponents. (...) The possible outcome of the competition between the TFT strategy and non-cooperative strategies is considered. It turns out that even small number of TFT strategies can overcome the greater number of more “egoistic” strategies.The described model can give the better understanding of some psychological, sociological and biological processes as well as help to propagate the altruistic attitudes in the society.

This is illustrated with an analysis of four small stories taken from daily life in which people are in agony because they do not know what to do.

We introduce a notion of a real game (a generalisation of the Karchmer-Wigderson game (cf. [3]) and of real communication complexity, and relate this complexity to the size of monotone real formulas and circuits. We give an exponential lower bound for tree-like monotone protocols (defined in [4, Definition 2.2]) of small real communication complexity solving the monotone communication complexity problem associated with the bipartite perfect matching problem. This work is motivated by a research in interpolation theorems for prepositional logic (...) (by a problem posed in [5, Section 8], in particular). Our main objective is to extend the communication complexity approach of [4, 5] to a wider class of proof systems. In this direction we obtain an effective interpolation in a form of a protocol of small real communication complexity. Together with the above mentioned lower bound for tree-like protocols this yields as a corollary a lower bound on the number of steps for particular semantic derivations of Hall's theorem (these include tree-like cutting planes proofs for which an exponential lower bound was demonstrated in [2]).

The general thrust of Neil Levy's paper is that a certain amount of paternalism should be viewed as compatible with liberalism.1 I am not quite convinced that what he is defending is properly paternalism. In addition, I am not entirely sure what his proposal is. Here are a few comments about several points in the paper.1. A possibly small question is worth raising when Levy says, ‘That is, the state may not interfere with individuals’ actions, even to promote their (...) own conception of the good. This claim is typically justified on epistemic grounds: individuals are best placed to judge for themselves how to pursue their conception of the good.’But I don't think that this is quite the right picture, though admittedly, it has often been suggested by liberals. Still: if it's a matter of ‘epistemic’ grounds, then that implies that there is something out there to be known, so that the question is, how do we go about knowing it? But this way of putting it is misleading. For liberalism says that whenever anybody, B, other than the individual we are considering, say A, claims that what is good for A is something ‘out there’—something that can strongly contradict what A thinks for his own case—then that outsider has no authority to override A's preference. This isn't epistemic—it's a moral position.If we were to talk of ‘epistemic’ here, presumably what is known in this case is how the individual …. (shrink)

We prove that the property characterizes Σ‐algebraically compact modules if is not ω‐measurable. Moreover, under a large cardinal assumption, we show that over any ring R where is not ω‐measurable, any free module M of ω‐measurable rank satisfies, hence the assumption on cannot be dropped in general (e.g., over small non‐right perfect rings). In this way, we extend results from a recent paper by Simion Breaz.

Aim and MethodsThis perspective presents evidence of mature gratitude as a way of coping with the threats and boundaries of coronavirus disease 2019 (COVID-19). This narrative, non-systematic review will be based on studies from the COVID-19 period in association with more general literature on the characteristics of mature gratitude related to good mental health.ResultsThe results from the literature suggest that a confrontation with our existential vulnerability during a pandemic is not only a crisis but also an opportunity to view our (...) lives in a different way. Mature gratitude, as proposed in this perspective, can help us in coping with the threats and boundaries that are part of our lives due to the COVID-19 pandemic. This time of crisis gives us the opportunity to self-reflect on our current life and plans for the future and to reframe them through a positive lens which can encourage individuals to actively strengthen their psychological resilience and coping skills.ConclusionCultivating an attitude of mature gratitude through actions of kindness, expressing being thankful for life and God, and enjoying all the small things in life helps in coping with the current threats of COVID-19 and building lifelong resilience for the future. Knowledge about these associations can help psychologists, counselors, and coaches to support people who experience psychological issues due to the current pandemic and all crises to come. (shrink)

Time discounting is the phenomenon that a desired result in the future is perceived as less valuable than the same result now. Economic theories can take this psychological fact into account in several ways. In the economic literature the most widely used type of additive time discounting is exponential discounting. In exponential discounting, the fall of valuation depends by a constant factor on the length of the delay period. It is well known, however, that exponential time discounting often does not (...) describe well how people actually behave. Most people are averse to short delays in gratification now, while their future selves may not mind a bit of extra waiting. This behaviour can be described well by non-exponential discounting functions such as hyperbolic discounting. In hyperbolic discounting, valuations fall rapidly for small delay periods, but the fall gets slower for longer delay periods. Hyperbolic discounting captures phenomena such as procrastination, addiction and in general inconsistency over time. This chapter investigates whether forms of non-exponential discounting, in particular close to the so called Quasi-Hyperbolic model, could also be characterized in terms of dynamically consistent choices when individuals discount the welfare of future selves as well as their payoffs.

Evaluative learning refers to the change in the affective evaluation of a previously neutral stimulus that occurs after the stimulus has been associated with a second, positive or negative, affective stimulus . Four experiments are reported in which the AS was presented very briefly. Significant evaluative learning was observed in participants who did not notice the presentation of the affective stimuli or could not discriminate between the briefly presented positive and negative ASi when asked to do so . In two (...) other experiments , no significant learning effect was obtained. A meta-analysis performed on the present and previously reported results gave evidence for a small, though statistically reliable evaluative learning effect when ASi are presented “subliminally.” This finding supports the hypothesis that evaluative associations can be learned implicitly.

Machine learning (ML) is increasingly used to enhance production systems and meet the requirements of a rapidly evolving manufacturing environment. Compared to larger companies, however, small- and medium-sized enterprises (SMEs) lack in terms of resources, available data and skills, which impedes the potential adoption of analytics solutions. This paper proposes a preliminary yet general approach to identify low-cost analytics solutions for manufacturing SMEs, with particular emphasis on ML. The initial studies seem to suggest that, contrarily to what is usually (...) thought at first glance, SMEs seldom need digital solutions that use advanced ML algorithms which require extensive data preparation, laborious parameter tuning and a comprehensive understanding of the underlying problem. If an analytics solution does require learning capabilities, a ‘simple solution’, which we will characterise in this paper, should be sufficient. (shrink)

The history of twentieth-century American psychology is often depicted as a history of the rise and fall of behaviorism. Although historians disagree about the theoretical and social factors that have contributed to the development of experimental psychology, there is widespread consensus about the growing and declining influence of behaviorism between approximately 1920 and 1970. Since such wide-scope claims about the development of American psychology are typically based on small and unrepresentative samples of historical data, however, the question rises to (...) what extent the received view is justified. This paper aims to answer this question in two ways. First, we use advanced scientometric tools to quantitatively analyze the metadata of 119.278 papers published in American journals between 1920 and 1970. We reconstruct the development and structure of American psychology using co-citation and co-occurrence networks and argue that the standard story needs reappraising. Second, we argue that the question whether behaviorism was the ‘dominant’ school of American psychology is historically misleading to begin with. Using the results of our bibliometric analyses, we argue that questions about the development of American psychology deserve more fine-grained answers. (shrink)

Inequality of incomes is one of the significant factors forming the social capital. Two views dominate among economists dealing with the influence of inequality of income on economic growth. On the one hand, a too low inequality of income does not motivate people to increase the labour productivity. A low inequality of income might result from an extended social care system and overloading GDP with social transfers. A good example of it may be a situation when the unemployed refuses to (...) accept a job offer and prefers the unemployment benefit rather to a slightly higher salary. Moreover, a lack of incentives for the employee who fails to acknowledge the economic sense of increasing the productivity of his work might lead to the slower growth of economy. On the other hand, a contrary view suggests that an increase of the inequality of income has a negative impact on the economy. The accumulation of wealth by a small number of citizens raises doubts about good use of that wealth for investments necessary for the growth of the economy. An excessive inequality of income is confronted with disapproval of the significant part of society and regarded as unfair and unjustified. It may also increase the crime level and decrease the trust and, more generally, lead to the weakening of social capital. The arguments above lead to a hypothesis that the influence of the inequality of income on the growth of the economy has a non-linear character. We confirmed this hypothesis in growth models of the US and Swedish economies. We assess the historically optimal inequality of income measured by the Gini coefficient at 46% and 24% for the US and Sweden respectively. The optimal inequality of income in Poland was assessed previously at 29%. The dissimilarities may result from the cultural differences, educational level differences, ethnic differences and differences in diligence. (shrink)

In a macroevolutionary timescale, evolvability itself evolves. Lineages are sorted based on their ability to generate adaptive novelties, which leads to the optimization of their genotype-phenotype map. The system of translation of genetic or epigenetic changes to the phenotype may reach significant horizontal and vertical complexity, and may even exhibit certain aspects of learning behaviour. This continuously evolving semiotic system probably enables the origin of complex yet functional and internally compatible adaptations. However, it also has a second, “darker”, side. As (...) was pointed out by several authors, the same process gradually reduces the probability of the origination of significant evolutionary novelties. In a similar way to the evolution of societies, teachings, or languages, in which the growing number of internal linkages gradually solidifies their overall structure and the structure or interpretation of their constitutive elements, the evolutionary potential of lineages decreases during biological evolution. Possible adaptations become limited to small “peripheral” modifications. According to the Frozen Evolution theory, some of the proximate causes of this “macroevolutionary freezing” are more pronounced or present exclusively in sexual lineages. Sorting based on the highest evolvability probably leads to the establishment of certain structural features of complex organisms, e.g. the modular character of their development and morphology. However, modules also “macroevolutionary freeze” whereas the hypothetical “thawing” of modules or their novel adaptive combinations becomes rarer and rarer. Some possible ways out of this dead end include the rearrangement of individual development, e.g. neoteny, radical simplification, i.e. sacculinization, and transition to a higher level of organization, e.g. symbiosis or symbiogenesis. The evolution of evolvability is essentially a biosemiotic process situated at the intersection of the genocentric modern synthesis and the evo-devo-centric extended synthesis. Therefore, evolvability may eventually connect these three not necessarily contradictory approaches. (shrink)

Evolutionary changes and interspecific diversity in sexual coercion and autonomy are often linked to indirect selection on mate preferences. Yet, this approach overlooks the small fraction of indirect selection in total selection on mate choice and assumes unnecessarily specific conditions in the recent ‘autonomy-enhancing’ risk-reduction model. This paper proposes a more parsimonious approach based on direct selection and basic signalling theory, incorporating ecological variables to better explain sexual biodiversity. Particularly, the spatial dimensionality of mating environments is emphasized for its (...) role in enhancing sexual freedom through both diminishing monopolization and elevating escape potential from sexual coercion. Empirical evidence, ranging from waterfowl to humans, seems to better align with this ecologically constrained signalling perspective. Furthermore, it suggests that choosers keep coercion risk at ecological baseline by leveraging their escape potential. This repositions intriguing protective elements like bowerbirds' constructions as courtship features that have been bargained to respect sexual autonomy rather than enhancing it through indirect selection. It implies that courtship induced risks, such as reduced mobility, may in principle increase substantially precisely because they are offset by protective measures. Future research could reveal the prevalence of such risk-balancing strategies, advancing our understanding of mating dynamics. This work suggests new theoretical and empirical research avenues within the ecology of mating dynamics. (shrink)

This paper is about participation in efficient risk sharing among agents who have ambiguous beliefs about uncertain states of nature. The question we ask is whether and how can ambiguous beliefs give rise to some agents not participating in efficient risk sharing. Ambiguity of beliefs is described by the multiple-prior expected utility of Gilboa and Schmeidler, or the variational preferences of Maccheroni et al. :1447–1498, 2006). The main result says that if the aggregate risk is relatively small, then the (...) agents whose beliefs are the most ambiguous do not participate in risk sharing. The higher the ambiguity of those agents’ beliefs, the more likely is their non-participation. Another factor making non-participation more likely is low risk aversion of agents whose beliefs are less ambiguous. We discuss implications of our results on agents’ participation in trade in equilibrium in assets markets. (shrink)

Although critical differences exist between large companies and small‐ and medium‐sized enterprises (SMEs), limited empirical research has been done on human resource (HR)‐related corporate social responsibility (CSR). In this paper we study aging workforce management (AWM) as a component of CSR. Our study was conducted in the Netherlands through a randomly distributed online questionnaire. Managers and team leaders of 201 SMEs responded. The data were analyzed using multiple hierarchical regression analysis. Our results are twofold: first, findings suggest that CSR (...) policies in micro organizations with fewer than five employees seem to be strongly associated with AWM; and second, that companies with a focus on integration of older workers in daily activities do not perceive their actions as HR‐related. Using AWM as part of CSR helps to give insight into the role of the owner, company size and the nature of implicit CSR practices. Our study demonstrates that the use of AWM in CSR research can lead to valuable insights and therefore, our overarching research question is answered that AWM can be used when studying CSR. (shrink)

We investigate the possibility to characterize (multi) functions that are Σ b i -definable with small i (i = 1, 2, 3) in fragments of bounded arithmetic T 2 in terms of natural search problems defined over polynomial-time structures.

Aim: This article presents key ethical challenges that were encountered when conducting a participatory qualitative research project with a very specific, small group of nurses, in this case with practice development nurses in Malta. Background: With the small number of nurses employed in practice development roles in Malta, there are numerous difficulties of maintaining confidentiality. Poorly constructed interventions by the researcher could have resulted in detrimental effects to research participants and the overall trustworthiness of the research. Generally, ethical (...) guidelines for research exist to reinforce validity of research; however, there is not an established consensus on how these strategies can be utilised in some types of qualitative field work. Research design: The researcher used an exploratory case study methodology. The sample consisted of 10 participants who were interviewed twice using face-to-face interviews, over a period of 2 months. Ethical considerations: The study was ethically reviewed by the University Research Ethics Committee and the Faculty Research Ethics Committee, University of Malta. The participants referred to in this article have been given adequate information about the study and their consent has been obtained. Discussion: Numerous strategies for ensuring confidentiality during recruitment of the participants, during data collection, during transcription and data analysis and during dissemination of research results assisted the researcher in responding to potential and actual ethical issues. Conclusion: This article emphasises the main strategies that can be used to respond to ethical challenges when researching with a small easily identifiable group. The learning discussed here may be relevant to or even transferable to other similar research studies or research contexts. These methods fostered a greater credibility throughout the research process and predisposed the participants to greater trust, and thus, they disclosed their experiences and speak more freely, thus enhancing the quality of the study.

This paper urges that if we wish to give social intelligence to our agents, it pays to look at how we acquired our social intelligence ourselves. We are born with drives and motives that are innate and deeply social. Next, as children we are socialized to acquire norms and values and to understand rituals large and small. These social elements are the core of our being. We capture them in the acronym GRASP: Groups, Rituals, Affiliation, Status, Power. As a (...) consequence, economic rationality or logical reasoning do not suffice when it comes to social intelligence. Basic features of our social behaviour, of the kind that one sees early in the lives of children, need to be prominent. These include fear, love, and aggression. They extend to the combination of these drives with basic social clues from the environment such as big and small, good and bad, as well as culture-specific specializations of these. This will make agents respond differentially to inferred attributes such as gender, age, group membership. This level of universality in social intelligence should receive our full attention. The general insights gained can then be re-used in myriad implementations to specific modelling issues. (shrink)

Measurement error is omnipresent in psychological data. However, the vast majority of applications of autoregressive time series analyses in psychology do not take measurement error into account. Disregarding measurement error when it is present in the data results in a bias of the autoregressive parameters. We discuss two models that take measurement error into account: An autoregressive model with a white noise term (AR+WN), and an autoregressive moving average (ARMA) model. In a simulation study we compare the parameter recovery performance (...) of these models, and compare this performance for both a Bayesian and frequentist approach. We find that overall, the AR+WN model performs better. Furthermore, we find that for realistic (i.e., small) sample sizes, psychological research would benefit from a Bayesian approach in fitting these models. Finally, we illustrate the effect of disregarding measurement error in an AR(1) model by means of an empirical application on mood data in women. We find that, depending on the person, approximately 30–50% of the total variance was due to measurement error, and that disregarding this measurement error results in a substantial underestimation of the autoregressive parameters.

The aim of this study was to explore stakeholder perceptions of the contribution of an Automatic Milking System (AMS) to sustainable development of organic dairy production in Denmark and the Netherlands. In addition, reasons for the current difference in AMS use on organic dairy farms between both countries were explored. To answer above mentioned aims, farmers and advisors in both countries were interviewed using a focus group approach. Questions of the interviews were based on a literature review on sustainability issues (...) affected by introduction of AMS. Participants expressed no moral problems regarding AMS use. They, however, pointed out uncertainty about the economic gain, difficulties with grazing, adaptation problems to technology, and image problems towards consumers. The latter results from a reduction in grazing time affecting both animal welfare and product quality. The participants did not recognize eutrophication, as result of high stocking density on farmstead lots, as a problem caused by AMS. The milk quality problem related to AMS use, although acknowledged as crucial towards consumers, was not prioritized very highly, especially not by the farmers in both countries. All groups were, however, unanimous in their perception of how important image was as far as the consumers are concerned. The perception analysis revealed that Dutch participants were more concerned about the economic payoff of AMS use, and showed more reluctance towards enlargement than Danish ones. In addition, they acknowledged the small-scale naturalness of organic production. These differences in perception could possibly explain observed differences in AMS use in organic dairy production between Denmark and the Netherlands. (shrink)

This review article presents an important, newly published study of Popper's critical method by Zbigniew Liana. The review emphasizes the very high level of the study, points to its originality, and explains why the book is recommended mainly to specialists of Popper's thought. It is also explained how the book manages to contain so many original and valuable analyses in a small volume.

The Jeffreys–Lindley paradox exposes a rift between Bayesian and frequentist hypothesis testing that strikes at the heart of statistical inference. Contrary to what most current literature suggests, the paradox was central to the Bayesian testing methodology developed by Sir Harold Jeffreys in the late 1930s. Jeffreys showed that the evidence for a point-null hypothesis $${\mathcal {H}}_0$$ H 0 scales with $$\sqrt{n}$$ n and repeatedly argued that it would, therefore, be mistaken to set a threshold for rejecting $${\mathcal {H}}_0$$ H 0 (...) at a constant multiple of the standard error. Here, we summarize Jeffreys’s early work on the paradox and clarify his reasons for including the $$\sqrt{n}$$ n term. The prior distribution is seen to play a crucial role; by implicitly correcting for selection, small parameter values are identified as relatively surprising under $${\mathcal {H}}_1$$ H 1. We highlight the general nature of the paradox by presenting both a fully frequentist and a fully Bayesian version. We also demonstrate that the paradox does not depend on assigning prior mass to a point hypothesis, as is commonly believed. (shrink)

Exploratory analyses are an important first step in psychological research, particularly in problem-based research where various variables are often included from multiple theoretical perspectives not studied together in combination before. Notably, exploratory analyses aim to give first insights into how items and variables included in a study relate to each other. Typically, exploratory analyses involve computing bivariate correlations between items and variables and presenting them in a table. While this is suitable for relatively small data sets, such tables can (...) easily become overwhelming when datasets contain a broad set of variables from multiple theories. We propose the Gaussian graphical model as a novel exploratory analyses tool and present a systematic roadmap to apply this model to explore relationships between items and variables in environmental psychology research. We demonstrate the use and value of the Gaussian graphical model to study relationships between a broad set of items and variables that are expected to explain the effectiveness of community energy initiatives in promoting sustainable energy behaviors.

A layoff is a threatening yet common event which employees might face at some point in their working lives. In two scenario-based experiments, we investigated which actions of a layoff agent during a dismissal notification meeting may contribute to laid-off employees’ fairness judgments and negative attitudes toward the employer. In general, the extent to which layoff victims were treated with respect was consistently found to increase perceptions of interpersonal and procedural fairness and to mitigate negative attitudes toward the employer. Further (...) results showed that layoff victims preferred to be given an adequate explanation of the reasons for the layoff and to receive notice from the direct supervisor. Relationships between the layoff agent’s actions and layoff victims’ negative attitudes toward the employer were mediated by perceptions of procedural fairness. In addition, delegating the layoff agent’s task to an external consultant increased perceived psychological contract breach. Our findings have important implications for organizational justice research and for the managerial practice of implementing fair layoffs. In particular, small actions, such as treating employees with respect, might be of benefit both to humans and organizations. (shrink)

Ecologists are challenged by the need to bridge and synthesize different approaches and theories to obtain a coherent understanding of ecosystems in a changing world. Both food web theory and regime shift theory shine light on mechanisms that confer stability to ecosystems, but from different angles. Empirical food web models are developed to analyze how equilibria in real multi-trophic ecosystems are shaped by species interactions, and often include linear functional response terms for simple estimation of interaction strengths from observations. Models (...) of regime shifts focus on qualitative changes of equilibrium points in a slowly changing environment, and typically include non-linear functional response terms. Currently, it is unclear how the stability of an empirical food web model, expressed as the rate of system recovery after a small perturbation, relates to the vulnerability of the ecosystem to collapse. Here, we conduct structural sensitivity analyses of classical consumer-resource models in equilibrium along an environmental gradient. Specifically, we change non-proportional interaction terms into proportional ones, while maintaining the equilibrium biomass densities and material flux rates, to analyze how alternative model formulations shape the stability properties of the equilibria. The results reveal no consistent relationship between the stability of the original models and the proportionalized versions, even though they describe the same biomass values and material flows. We use these findings to critically discuss whether stability analysis of observed equilibria by empirical food web models can provide insight into regime shift dynamics, and highlight the challenge of bridging alternative modelling approaches in ecology and beyond.

Hunger striking is a form of nonviolent action of last resort. It is a tactic used by powerless individuals to challenge those in power and achieve change. Many authors have emphasized that hunger strikers are not suicidal, but when oppressed people run out of other ways to protest or demand sociopolitical change, some of them are willing to place their health and life at risk to achieve their goals. Hunger strikes have a long, widely diffused history, and studies reveal that (...) they are typically small, brief, and often successful. Some well-known examples are the fasts of the suffragettes in the UK, of IRA... (shrink)

The aim of this article is to present the voyages made in the second half of the 14th century by Queen Jadwiga of Poland, the wife of the first Jagiellonian ruler on the Polish throne. Ladislaus Jagiełło ruled over a vast area of the Polish and Lithuanian states, like other European monarchs, through an itinerary system around his realm. Jadwiga accompanied her husband in the performance of his monarchical duties, and sometimes replaced him, but her trips were not only political (...) or representative. The queen also traveled, perhaps even primarily, for family and private functions. During her travels, she most often visited the royal lands of Lesser Poland, and less often went to other regions of the country or beyond its borders. The sources used in this research are narrative and, it should be noted, do not come directly from the period of Jadwiga’s life. These are the Annals of Jan Długosz, written several decades later, which provide information about the time and place of the journeys made by the queen. However, they make it possible to learn – to a far greater extent than other sources – about the circumstances which induced the Queen consort Jagiełło to leave the walls of the Wawel Castle. The study of the subject is also possible thanks to the itinerary of Queen Jadwiga, compiled by Grażyna Rutkowska, which enables analysis beyond the findings concerning the timetable of these trips and corrects the coverage by the Polish chronicler. The literary division of royal travels into “small” and “great” allows us to see the difference not only in territorial range, but above all in the nature and purpose of travels made by the Queen. Jadwiga liked staying in the royal estates of Małopolska using the time for recreation, but when necessary, she also made the effort to travel to more distant towns to join in the implementation of state policy.

This article analyzes the lectures and texts from the last period of Czech philosopher Jan Patočka, one of the last disciples of Edmund Husserl, the founding father of phenomenology. The point of departure is Patočka’s critical reception of Husserl’s concept of the crisis of European mankind. There are, however, two other elements distinctive of Patočka’s thought essential for this interpretation. First, he was a classical philosopher aiming at Socratic ‘care for the soul’. Second, he approached the theme of universal human (...) history from his own unique historic position: as a Czech philosopher, involved in the Socratic manner primarily with his own Czech national community, for whom the big question of the future of European mankind and its legacy at the end of its golden modern age is inseparably connected with a ‘small’ one: the question of Czech national existence – the question of the future of his nation in a changing world and the issue of its freedom.

This paper completes a small but long desiderated act of restitution to the Euripidean scholarship of J. J. Scaliger.In 1694 Joshua Barnes published at Cambridge a complete edition of Euripides; he included either in his text or notes a number of conjectures transcribed from marginalia in a copy of W. Canter's Euripides owned successively by Scaliger, his pupil Daniel Heinsius, to whom Scaliger bequeathed the book, and Jan Rutgers. The book passed to the Bodleian Library at Oxford ; in (...) the early nineteenth century P. Elmsley re-examined it for his editions of Medea and Bacchae, and complained that Barnes had not only failed to report all Scaliger's conjectures but frequently disguised the source of those he had noted or even silently appropriated them to himself.
