    The crystal structures of 1,6-diazabicyclo[4.4.4]tetradecane (1) and of its inside-protonated ion (2), which were originally described in space group C2/c, should be described instead in trigonal space groups, (1) in R3c and (2) in P31c; both moieties have crystallographically imposed point symmetry D_3 rather than C_2

    Understanding the Drivers of Sustainable Entrepreneurial Practices in Pakistan’s Leather Industry: A Multi-Level Approach

    Purpose: The main objective is to analyse the drivers of sustainable entrepreneurial practices in SMEs operating in a developing economy. The secondary objectives are to explore the relationship between these drivers and to draw out the implications for policy and practice. Design/methodology/approach: The research is informed by the literature on sustainable entrepreneurship, and on the drivers of pro-environmental practices in SMEs. It reports on the results of an intensive multi-level empirical study, which investigates the environmental practices of SMEs in Pakistan’s leatherworking industry using a multiple case study design and grounded analysis, which draws on relevant institutional theory. Findings: The study identifies that coercive, normative and mimetic isomorphic pressures simultaneously drive sustainable entrepreneurial activity in the majority of sample SMEs. These pressures are exerted by specific micro, meso and macro level factors, ranging from international customers’ requirements to individual-level values of owners and managers. It also reveals the catalytic effect of the educational and awareness-raising activities of intermediary organisations, in tandem with the attraction of competitiveness gains, (international) environmental regulations, industrial dynamism and reputational factors. Practical implications: The evidence suggests that, in countries where formal institutional mechanisms have less of an impact, intermediary organisations can perform a proto-institutional role that helps to overcome pre-existing barriers to environmental improvement by sparking sustainable entrepreneurial activity in SME populations. Originality/value: The findings imply that the drivers of sustainable entrepreneurial activity do not operate in a ‘piecemeal’ fashion, but that particular factors mediate the emergence and development of other sustainability drivers. This paper provides new insights into sustainable entrepreneurship and motivations for environmental practices in an under-researched developing economy context

    The Castello Plan-Evidence of Horticulture in New Netherland or Cartographer\u27s Whimsy?

    Few descriptions or depictions of horticulture in New Netherland have come down to us, although 17th-century observers\u27 accounts of gardens and orchards present lengthy lists of fruits, vegetables, \u27and fiowers transplanted from Europe, as well as those discovered in North America. Perhaps the most evocative source is the mid-century Castello Plan, a view of the settlement af New Amsterdam, which shows elaborate · parterres on most of the unoccupied lots. Are the gardens of the Castello Plan fact, or simply cartographer\u27s whimsy? Based on data from both the Netherlands and New Netherland-including artists~ depiction~, travelers\u27 accounts, and gardening texts-that illustrate the cultural attitudes, cultural materials, and enviro\u27n~ ment the colonists would have known in Europe, the images of gardens depicted on this early view of Manhattan are evaluated
