Topological Phase Transitions

The role of topological excitations in frustrated Heisenberg antiferromagnets between two and three spatial dimensions is considered. In particular, the antiferromagnetic Heisenberg model on a stacked triangular geometry with a finite number of layers is studied using Monte Carlo methods. A phase transition that is purely topological in nature occurs at a finite temperature for all film thicknesses. The results indicate that topological excitations are important for a complete understanding of the critical properties of the model between two and three dimensions.

In the world city theory, most researchers focus on the service sector in the urban economy and less discuss the role of manufacturing. However, the path of only emphasizing financial and corporate service could not fit the sustainability concept. Compared to Anglo-American world city, Global South’s world cities have distinct pathway to be industrialization, tertiarization and globalization. This paper adopted dynamic historic perspective with first-hand materials including in-depth interviews with managers and government officers and second-hand data including yearbook statics and economic census to closely examine the emerging world city-- ‘World Factory’ in Global South, Guangzhou in China, from 1949 to 2015, to emphasize how manufacturing affects the urban globalization through three dimensions, economic, social and spatial dimensions. To make the confirmation of the role of manufacturing in Guangzhou as sustainable world city, we find manufacturing in Guangzhou builds up the basic foundation of export-oriented economy and makes positive effects on urban economic transformation. In addition, manufacturing remains important source of employment and foreign immigration. Along with urbanization and industrialization, urban spatial expansion and aggregation changes with different urban development concept. We provide new insights on multiple globalization on manufacturing for sustainable world city.

Abstract This article looks at the relationship between psychological contract breach and voluntary turnover among newcomers, using supervisor trustworthiness as a mediator and negative affectivity as a moderator. Relying on data from 243 newcomers, psychological contract breach was found to be negatively related to the three dimensions of supervisor trustworthiness, i.e., ability, benevolence, and integrity. Supervisor integrity further mediated a positive relationship between psychological contract breach and voluntary turnover measured 8 months later. Psychological contract breach interacted with negative affectivity such that it was less negatively related to dimensions of supervisor trustworthiness at high levels of negative affectivity. The indirect relationship of psychological contract breach to voluntary turnover as mediated by supervisor integrity was also weaker at high levels of negative affectivity. We discuss the implications of these findings for research and practice.

Intolerance of uncertainty (IU) refers to the tendency to fear the unknown and to worry excessively about potential future negative outcomes. In the career decision-making process, college students experience uncertainty regarding the future of occupational opportunities and the evolution of their interests and capabilities. Anxiety is a well-established predictor of career indecision. Therefore, this study examined the role of anxiety as a mediator in the relation of IU and rumination to three dimensions of career decision making difficulties among college students ( N = 678). Results of path analyses indicated that as hypothesized, after controlling for age, intolerance of uncertainty was directly and indirectly (though anxiety) related to the three dimensions of career decision making difficulties: lack of readiness, lack of information, and inconsistent information. Results suggested that career choice interventions may be enhanced with a targeted emphasis on coping with the uncertainty involved in career decision making among college students.

AbstractThis paper provides an overview of the features of caregiver input that facilitate language learning across early childhood. We discuss three dimensions of input quality: interactive, linguistic, and conceptual. All three types of input features have been shown to predict children's language learning, though perhaps through somewhat different mechanisms. We argue that input best designed to promote language learning is interactionally supportive, linguistically adapted, and conceptually challenging for the child's age/level. Furthermore, input features interact across dimensions to promote learning. Some but not all qualities of input vary based on parent socioeconomic status, language, or culture, and contexts such as book-reading or pretend play generate uniquely facilitative input features. The review confirms that we know a great deal about the role of input quality in promoting children's development, but that there is much more to learn. Future research should examine input features across the boundaries of the dimensions distinguished here.

The Impact

The notion of a polaron, originally introduced in the context of electrons in ionic lattices, helps us to understand how a quantum impurity behaves when being immersed in and interacting with a many-body background. We discuss the impact of the impurities on the medium particles by considering feedback effects from polarons that can be realized in ultracold quantum gas experiments. In particular, we exemplify the modifications of the medium in the presence of either Fermi or Bose polarons. Regarding Fermi polarons we present a corresponding many-body diagrammatic approach operating at finite temperatures and discuss how mediated two- and three-body interactions are implemented within this framework. Utilizing this approach, we analyze the behavior of the spectral function of Fermi polarons at finite temperature by varying impurity-medium interactions as well as spatial dimensions from three to one. Interestingly, we reveal that the spectral function of the medium atoms could be a useful quantity for analyzing the transition/crossover from attractive polarons to molecules in three-dimensions. As for the Bose polaron, we showcase the depletion of the background Bose-Einstein condensate in the vicinity of the impurity atom. Such spatial modulations would be important for future investigations regarding the quantification of interpolaron correlations in Bose polaron problems.

Purpose The purpose of this paper is to evaluate the role of farm-to-table (FTT) activities in agritourism towards sustainable development based on three agritourism farms in Brunei. Design/methodology/approach The study is based on qualitative data using semi-structured interviews with 23 participants involved in the management of the farms. In-depth interviews are considered the most appropriate approach to gain the unexplored perspectives of the agriculture community at the three agritourism farms. Findings The study found that FTT activities imparted in agritourism contribute towards sustainable development economically, socially and environmentally. FTT leads to the establishment of small medium and micro enterprises, which, in turn, creates employment for the local people. It also plays a part in preserving the ethno-culinary heritage of indigenous food, promoting food localism and sustainable agriculture. These findings suggest that FTT activities play an important role in revitalizing the local community. The outcome of this empirical research may enable planners to better formulate regional policy based on a balanced approach taking into account the three dimensions of sustainability towards agritourism development. From a theoretical standpoint, this study adds value to the literature by identifying the contributions of FTT activities towards sustainable development emphasising on the consumption of local ethnic food and food localism. Originality/value The contributions of agritourism for local farms has not been extensively discussed especially in Brunei’s local agriculture industry. This study will provide evidence that FTT activities contribute towards a moderate form of food activism; one that re-forges the disrupted linkages between people, nature and cultural heritage.

Alliance Portfolios

Purpose The purpose of this paper is to focus on the operation strategy of high-performance alliance portfolios by analyzing the effect of alliance portfolios on the performance of focal firms, using post-structuralism of social network theory and contingency theory. In detail, this paper refines alliance portfolios into three dimensions, and studies the moderating role of context on the relation between alliance portfolios and firm performance. Design/methodology/approach The empirical study was carried out with second-hand data gathered from Internal Revenue Service. In total, this paper gathered data from 506 focal firms in Zhejiang Province from 2001 to 2010 as the sample to test the hypotheses. Findings Based on the empirical results, the authors find the positive effect of relational dimension (weak alliance portfolios) and partner dimension (the diversity of partners) on performance. The effect of the former will become weaker with the increasing environmental dynamic, while the effect of the latter will become stronger. However, the structural dimension (alliance portfolios size) and relational dimension (new partners) have the negative effect on performance. And the negative effect will become stronger under high environmental dynamic. Moreover, the negative effect of non-local partners on performance becomes stronger when the environmental dynamic is high. Research limitations/implications The paper reveals that with the industry transformation caused by “internet +,” companies have been required go beyond traditional dyadic alliance management perspective. That is to say, individual alliance relationship should be seen as a part of a much broader picture of alliance portfolio. As such, the framework may help companies to manage their alliance portfolios by matching high-performance alliance portfolios to the external environment to produce a synergistic effect (Lea et al., 2006; Tritos et al., 2013; Keith et al., 2014) taking the characteristics of the configuration of alliance portfolios into consideration. Originality/value The paper presents a model that explains the effect of three dimensions of alliance portfolios on the performance of focal firms in different contexts through empirical study. This paper also integrates post-structuralism of social network theory and contingency theory to enable the understanding on the configuration of alliance portfolios.

Thriving At Work

PurposeThe purpose of this paper is to examine the contribution of agentic work behaviour and decision-making authority (DMA) to thriving at work and, more importantly, the moderating role of DMA in the relationship between agentic behaviour and thriving.Design/methodology/approachThe study has been carried out upon a random sample of 330 employees below supervisory level from manufacturing companies located at Odisha (a state located at the eastern part of India). After verifying the significance of correlation among the study variables through Pearson’s product moment correlation, moderated regression analyses were carried out to examine the independent contribution of agentic work behaviour and DMA to thriving as well as the moderating contribution of DMA towards thriving.FindingsResults reveal that the three dimensions of agentic work behaviour, namely, task focus, exploration and heedful relation, have a direct positive contribution towards thriving at workplace. As far as the moderation is concerned, it is observed that the thriving level is higher for the employees having high DMA irrespective of the level of agentic work behaviour at each dimension.Research limitations/implicationsThe findings imply for designing interventions to enhance task focus, super-ordinate relationship and interest for learning. In addition, the organisations should provide autonomy to employees for decision making.Originality/valueThe study is first of its kind in the Indian context upon employee thriving. In this study, the authors have not only investigated the separate independent contribution of agentic behaviour and DMA, but also their interacting contribution to employee thriving.
