AbstractVaesen argues that functional knowledge differentiates humans from non-human primates. However, the rationale he provides for this position is open to question – with respect to both the underlying theoretical assumptions and inferences drawn from certain empirical studies. Indeed, there is some recent empirical work that suggests that functional fixedness is not necessarily uniquely human. I also question the central role of stable function representations in Vaesen's account of tool production and use.

Natural disaster losses have been increasing worldwide. Insurance is thought to play a critical role in improving resilience to these events by both promoting recovery and providing incentives for investments in hazard mitigation. This review first examines the functioning of disaster insurance markets broadly and then turns to reviewing empirical studies on the role of natural disaster insurance in recovery and the impacts of disaster insurance on incentives for ex ante hazard mitigation and land use. Rigorous empirical work on these topics is limited. The work that has been done suggests that insurance coverage does improve recovery outcomes, but impacts on risk reduction may be modest. More studies comparing outcomes across insured and uninsured properties are needed, particularly for better understanding the role of insurance in climate adaptation.

While considerable literature has explored the complex nature of victimisation, few empirical studies have examined the role of alcohol and other drugs (AODs) in victims’ experiences, specifically victims’ self-medication using AODs and its impact on ongoing health and welfare needs. Addressing the dearth of empirical research on the nature and extent of victims’ self-medication, and drawing upon quantitative data from a survey ( n = 102) of victims from Adelaide, South Australia this article explores individuals’ experiences of victimisation and AOD use against type of victimisation, type of peer support network and type of consumption. The findings indicate support for the self-medication for trauma hypothesis, namely that victimisation is positively associated with considerable increase in AOD consumption. On the other hand, there is a lack of support for the supplementary hypothesis that network support is associated with victimisation/re-victimisation. The authors demonstrate that further empirical work is needed to deepen understanding of victims’ AOD use and expedite the development of evidence-based policy and support frameworks.

The Behavioral Theory of the Firm suggests that performance below an aspiration triggers problemistic search that can lead to organizational change and risk-taking. This compelling perspective has spawned considerable empirical examination of diverse strategic outcomes as firms’ responses to performance feedback. However, empirical studies have provided inconsistent evidence of problemistic search effects on various organizational search outcomes. This empirical controversy is likely attributed to the fact that most research has considered problemistic search as a firm-level and relatively routinized process with a high degree of automaticity in firms’ responses to performance feedback while overlooking the role of managerial agency. Rather than viewing problemistic search as an automatic firm-level process, we believe that behavioral responses are shaped, at least partially, by top executives, notably CEOs. To this end, we first examine whether problemistic search effects vary across a range of organizational change and risk outcomes. We then explore whether the relative size of firm and CEO effects varies across different search outcomes. Using a multilevel approach, we show not only the heterogeneity in problemistic search effects on different organizational outcomes but also heterogeneity in the relative size of firm and CEO effects on these outcomes. While firm effects are substantial in directing some strategic decisions, as proposed by the problemistic search model, CEO effects are large for certain organizational outcomes, such as changes in resource allocation. This study serves as a jumping-off point for future theorizing and empirical work on problemistic search that incorporate the role of managerial agency.

AbstractA mathematics textbook can be described as an officially authorized and pedagogically designed mathematics book written to provide mathematical knowledge to students. This description suggests the authority of the textbook - because it has been authorized by an administrative source and because it deals with authorized knowledge. This paper provides an overview of research on mathematics textbooks. The emphasis is on questions concerning the extent to which and how textbooks are used in mathematics education in Croatia and in the world.Research results show that mathematics textbooks are widely used in mathematics education worldwide. This finding points to the need for research on the content and structure of textbooks. Such studies are combined with the associated results on how textbooks are used in the classroom and which methods teachers apply in using textbooks in mathematics education. The results of the empirical studies show that teachers use textbooks for lesson preparation and pupils use mathematics textbooks for exercises to a great extent. These results imply that such an important role of textbooks in mathematics education deserves additional attention, with the goal of understanding and improving mathematics education.Key words: mathematics education; overview; research on textbook---SažetakMatematički udžbenik može se opisati kao službeno autorizirana i pedagoki osmiljena matematička knjiga napisana s ciljem da učenicima ponudi matematičke sadržaje.

We discuss the role of linguistic metaphors as a cognitive frame for the understanding of genetic information processing. The essential similarity between language and genetic information processing has been recognized since the very beginning, and many prominent scholars have noted the possibility of considering genes and genomes as texts or languages. Most of the core terms in molecular biology are based on linguistic metaphors. The processing of genetic information is understood as some operations on text – writing, reading and editing and their specification (encoding/decoding, proofreading, transcription, translation, reading frame). The concept of gene reading can be traced from the archaic idea of the equation of Life and Nature with the Book. Thus, the genetics itself can be metaphorically represented as some operations on text (deciphering, understanding, code-breaking, transcribing, editing, etc.), which are performed by scientists. At the same time linguistic metaphors portrayed gene entities also as having the ability of reading. In the case of such “bio-reading” some essential features similar to the processes of human reading can be revealed: this is an ability to identify the biochemical sequences based on their function in an abstract system and distinguish between type and its contextual tokens of the same type. Metaphors seem to be an effective instrument for representation, as they make possible a two-dimensional description: biochemical by its experimental empirical results and textual based on the cognitive models of comprehension. In addition to their heuristic value, linguistic metaphors are based on the essential characteristics of genetic information derived from its dual nature: biochemical by its substance, textual (or quasi-textual) by its formal organization. It can be concluded that linguistic metaphors denoting biochemical objects and processes seem to be a method of description and explanation of these heterogeneous properties.

The article analyzes the role of theories of embodied cognition for the development of emotion research. The role and position of emotions changed as philosophy developed. In classical and modern European philosophy, the idea of the “primacy of reason” prevailed over emotions and physicality, emotions and affective life were described as low-ranking phenomena regarding cognitive processes or were completely eliminated as an unknown quantity. In postmodern philosophy, attention focuses on physicality and sensuality, which are rated higher than rational principle, mind and intelligence. Within the framework of this approach, there is a recently emerged theory of embodied cognition, which allows to take a fresh look at the place of emotions in the architecture of mental processes – thinking, perception, memory, imagination, speech. The article describes and analyzes a number of empirical studies showing the impossibility of excluding emotional processes and the significance of their research for understanding the architecture of embodied cognition. However, the features of the architecture of embodied cognition remain unclear, and some of the discoveries of recent years (mirror neurons or neurons of simulation) rather raise new questions and require further research. The rigorously described and clear architecture of the embodied cognition can grow the theoretical basis that will allow to advance the studies of learning processes, language understanding, psychotherapy techniques, social attitudes and stereotypes, highlight the riddle of consciousness and create new theories of consciousness or even create an anthropomorphic artificial intelligence that is close to “strong artificial intelligence.”

Reversion to Islam while opening golden opportunities for a revert in terms of divine guidance and spiritual salvation is coming with somewhat insurmountable challenges in terms of Islamization of the self, family and contributions to the overall development of Malaysia as a multi-religious country. This is especially so when Islam as an official religion has made the issue of Islamization of the Malaysian society and its systems amongst the pivotal national agendas in the country.  As to what is the role of Chinese Muslims (reverts) in the process, studies, among others, have purported to present the statistics about their share in socio-economic development. Similarly, empirical studies point to the odds faced by this community at personal, family and community levels in their path for transition to the full Islamic way of life. To the presenters of this paper, however, the macro dimension of what it means to become a Muslim which is essential for adjustment to the Islamic requirements has not been sufficiently highlighted in discourses in the area. Accordingly, this paper presents the position statements on Islamic expectations from Chinese reverts with the purpose of motivating them to achieve greater things in the area of Islamization of their community and the nation to the effect. Keywords: Chinese converts, Islamization, expectations and challenges. Abstrak kembalinya seseorang kepada agama Islam selain dari membuka peluang keemasan dalam mendapat  petunjuk Ilahi dan pengisian rohani turut disertai dengan cabaran yang amat sukar untuk diatasi termasuklah cabaran Islamisasi diri, keluarga serta sumbangan kepada pembangunan keseluruhan Malaysia sebagai negara berbilang agama. Hal ini menjadi satu keutamaan terutamanya apabila Islam memegang status sebagai agama rasmi persekutuan yang menjadikan isu Islamisasi masyarakat Malaysia sebagai satu agenda nasional. Bagi menjayakan agenda ini, peranan umat Islam dari kalangan masyarakat Cina (cina muslim) juga perlu diambil kira. Statistik menunjukkan cina muslim turut mempunyai bahagian dalam menyumbang terhadap pembangunan sosio-ekonomi negara. Dalam pada masa yang sama, kajian empirikal membuktikan adanya bentuk bentuk cabaran yang dihadapi oleh komuniti ini di peringkat peribadi, keluarga dan komuniti dalam perjalanan mereka untuk kembali kepada cara hidup Islam yang sepenuhnya. Bagi kami pengkaji kertas ini, dimensi makro dalam menjadikan dan mengertikan  seseorang itu Muslim terutamanya dalam menyesuaikan diri dengan ajaran  Islam masih belum cukup diberi  penjelasan dan penerangan yang sewajarnya. Oleh itu, makalah ini cuba menerangkan idea dan cadangan yang berguna kepada cina muslim dengan tujuan memotivasikan  mereka bagi  mencapai kejayaan  yang lebih besar dari aspek Islamisasi di kalangan komuniti mereka seterusnya memberi sumbangan kepada negara. Kata kunci:  Cina Muslim, Islamisasi, harapan dan cabaran.

Inspired by recent epistemological and ontological debates aimed at unsettling and reshaping conceptions of language, this essay discusses how mainstream sociolinguistics offers notions meaningful for studying contexts of the South. Based on empirical studies of youth in two African cities, Yaoundé in Cameroon and Maputo in Mozambique, the essay engages with “fluid modernity” and “enregisterment” to unravel the role that fluid multilingual practices play in the social lives of urban youth. The empirically grounded theoretical discussion shows how recent epistemologies and ontologies offer inroads to more pluriversal knowledge production. The essay foregrounds: i) the role of language in the sociopolitical battles of control over resources, and ii) speakers’ reflexivity and metapragmatic awareness of register formations of fluid multilingual practices. Moreover, it shows how bundles of localized meanings construct belongings and counterhegemonic discourses, as well as demonstrating speakers’ differential valuations and perceptions of boundaries and transgressions across social space.

This study investigates how venture development programs such as private incubators, university incubators, and accelerators influence the success of participating nanotechnology startups. With the recent growth in such programs, empirical work is needed to compare their impact on participants across programs and with nonparticipants. Using data on firm bankruptcies, liquidation, government grants, and venture capital, we find benefits, but the influence of each venture development program varies greatly. We further investigate the influence of program services and resources to clarify program heterogeneity beyond existing typologies. The results clarify the role of these programs and ecosystem intermediaries.

The aim of this article was to identify the role of good mutual relationships with offerors for final purchasers, as well as define the meaning of the perception of offerors in the scope of listening to purchasers’ opinions and profiting from purchasers’ readiness to cooperate for the specificities of the prosumeric activity. A deep analysis of the world literature was used to prepare the theoretical part of this paper. The results of this analysis confirm the existing cognitive gap and research gap regarding mentioned aspects, including energy market. Empirical studies were conducted to reduce identified gaps. The survey method was used to collect primary data. The collected data were subjected to quantitative analysis, during which statistical analysis methods and tests were applied (Pearson chi-square independence test, V-Cramer factor analysis, Kruskal–Wallis test (KW), and exploratory factor analysis). The results of the statistical analysis and testing allowed the three research hypotheses formulated to be checked. Between the significance of good relationships with offerors and their perception, a statistically significant dependence was identified for all groups of offerors. The perception of offerors was a feature differentiating respondents’ opinions about the significance of good relationships with offerors for the two following groups: producers and traders. Additionally, the perception of offerors was a feature differentiating forms of prosumeric activity of respondents only for three interpurchase behaviors. The results obtained have a visible cognitive and applicability value. They contribute to the theory of marketing, as well as possibly facilitating the formation of good mutual relationships between offerors (including offerors of energy) and final purchasers as key partners cooperating with offerors in the marketing process. The approach presented in this paper has not been studied and analyzed so far, either in theoretical or in practical terms. This fact confirms its originality and value.
