Capability machines are a special form of CPUs that offer fine-grained privilege separation using a form of authority-carrying values known as capabilities. The CHERI capability machine offers local ...capabilities, which could be used as a cheap but restricted form of capability revocation. Unfortunately, local capability revocation is unrealistic in practice because large amounts of stack memory need to be cleared as a security precaution.
In this paper, we address this shortcoming by introducing
uninitialized capabilities
: a new form of capabilities that represent read/write authority to a block of memory without exposing the memory’s initial contents. We provide a mechanically verified program logic for reasoning about programs on a capability machine with the new feature and we formalize and prove capability safety in the form of a universal contract for untrusted code. We use uninitialized capabilities for making a previously-proposed secure calling convention efficient and prove its security using the program logic. Finally, we report on a proof-of-concept implementation of uninitialized capabilities on the CHERI capability machine.
Digital business transformation forces firms to develop foundational capabilities to remain competitive. However, despite considerable academic and managerial interest, the nature of a digital ...business capability (DBC) that creates value by effectively managing digital business transformation remains unclear. Drawing on a mixed-methods approach, we conceptualize and operationalize the DBC construct. In Study 1, we examine the effects of DBC on firm performance using a cross-industry, multisource dataset. In Study 2, we assess the effects of DBC on customer performance using a unique multisource, multilevel dataset collected at two points in time. The results reveal that DBC contributes to performance, even beyond the effects of established constructs. Importantly, DBC increasingly drives firm performance after reaching a critical level of internal dynamism (i.e., U-shaped moderation). By contrast, DBC particularly pays off at an optimal level of external dynamism (i.e., inverse U-shaped moderation). DBC is more valuable for business-to-consumer than for business-to-business firms.
Purpose
– Prior studies have argued that small firms with dynamic capabilities can revise and reconfigure their internal resources to meet the uncertainties of their business environment. However, ...there is a lack of understanding of how they can develop such critical capabilities. The purpose of this paper is to propose that small firms can employ information and communication technology (ICT) capabilities as a facilitator for developing dynamic capabilities. Thus, the study builds on resource-based view (RBV) literature and information systems (IS) literature by examining the influence of ICT capabilities on the dynamic capabilities of small firms.
Design/methodology/approach
– Several hypotheses were tested by analysing the survey data from 291 small high-technology firms in Sweden.
Findings
– The results reveal that ICT capabilities influence dynamic capabilities of small firms. More specifically, the ICT use for internal efficiency positively influences adoptive capabilities, collaborative use of ICT positively influences networking capabilities, and ICT use for communications positively influences both adaptive and innovation capabilities. Consequently, the results suggest that the different components of ICT capabilities facilitate the development of the different organizational capabilities that together represent dynamic capabilities and thus, can contribute to a small firm’s competitive advantage.
Practical implications
– This study has few implications for the managers and CEO’s of small high-technology firms. First, by prioritizing ICT capabilities, small firms can benefit from the development of dynamic capabilities that will support them to meet the challenges of turbulent business environment. Second, because small firms usually lack internal resources (i.e. financial resources and competence), the study provides more specific direction on how they can strategically invest and build different components of ICT that will positively influence their adaptive, absorptive, innovative, and network capabilities.
Originality/value
– The study provides an alternative view of how ICT capabilities influence the performance of small firms, and outlines how such capabilities influence the development of dynamic capabilities. Therefore, the study in hand contributes to the RBV and IS literature by specifically linking the components of ICT capabilities to dynamic capabilities and its related sub-capabilities.
In this study, we are interested in how export firms organize knowledge management and increase product innovation performance. Prior studies have concluded that knowledge transfer from external ...actors leads to operational performance outcomes; others have questioned the positive influence of buyer‐driven knowledge transfer activities on innovation performance. Drawing on absorptive capacity, we aim to offer a better understanding, how export firms as recipients of knowledge resources, organize their internal capabilities in order to realize firm‐level product innovation. This empirical study examines the interplay of buyer‐driven knowledge activities, resource acquisition and combining, and product innovation outcomes in the context of Pakistani export firms. Drawing on survey data from 239 export‐manufacturing firms, we test hypotheses using structural equation modeling. Our findings show that buyer‐driven knowledge transfer activities play a crucial role in enhancing export firms in absorbing and combining resources that lead to product innovation. The pragmatic suggestion of the research suggests that managers look closely at developing a culture of involvement with their buyers that promotes the development of knowledge resources. The results of this study have research, policy, and managerial implications.

ABSTRACT
Drawing upon organizational information processing theory, we investigate how explorative and exploitative information technology (IT) capabilities independently and interdependently ...moderate the relationship between supply chain information integration and firm performance. Data collected from 215 firms in China reveal that explorative IT capability positively moderates the relationship between information sharing and firm performance but exerts no moderating effect on the association between collaborative planning and firm performance. By contrast, exploitative IT capability positively moderates the impact of collaborative planning but negatively moderates the influence of information sharing on firm performance. Furthermore, building upon the ambidexterity perspective, we develop and test a three‐way interaction hypothesis that explorative and exploitative IT capabilities would interdependently moderate the relationship between supply chain information integration and firm performance. Our results indicate that explorative and exploitative IT capabilities are complementory in moderating the link between collaborative planning and firm performance but substitutive in moderating the relationship between information sharing and firm performance. By integrating insights from both information systems and operations management, our study thus provides an in‐depth understanding on how and when IT business value can be created in supply chain information integration context.

•Combined marketing-R&D capability enables early entry and product line breadth.•Early entry leads to narrower product lines – but more innovative products.•Early entrants and firms with broad ...product lines survive longer.•Order of entry plays a mediating role in capabilities-survival duration pathways.•Early entry and product line breadth are incompatible market entry strategies.
Using data on firm entries into the U.S. market for four product categories, we examine: (1) the complementary impact of marketing and R&D capabilities on firms’ market entry strategies, (i.e., entry timing, product innovativeness, and product line breadth); (2) the extent that entry timing mediates the relationship between marketing-R&D capability complementarity, product line breadth and product innovativeness; and, (3) the effects of the three market entry strategies on firms’ survival in the product categories. We provide three important contributions. First, we clarify the role of entry timing in influencing other market entry imperatives. Second, by providing evidence that both entry timing and product line breadth determine survival duration, we propose that the ‘optimal’ entry time varies along an entry-timing continuum. Third, we provide a more holistic examination of market entry considerations, which reveals the indirect relationship between marketing and R&D capability complementarity and survival through mediated paths.

The changes and uncertainty of the business environment in the VUCA era are serious challenges that must be faced, especially for SMEs. The unpreparedness of business actors to face these changes can ...impact the decline in SME performance and business sustainability. SMEs must continue to adapt to all changes that occur in their capabilities. Thus, SME players must have a business strategy using their resources by increasing dynamic entrepreneurial capabilities supported by financial resources to compete in the market. This research aims to analyze the relationship between digital technology capability, relational capability, innovation capability, financial resource development, and SMEs’ performance in Surakarta. The results of 120 SME respondents in Surakarta show that dynamic entrepreneurial capability, in this case, is measured using the variables digital technology capability (DTC), relational capability (RC), and innovation capability (IC) which are proven to have a significant influence on SMEs performance and also the development of financial resources can only partially mediate digital technology capability, however Financial resource development cannot mediate the influence of relational capability or innovation capability on SMEs performance. This research implies that it is important for SMEs to have dynamic entrepreneurial capabilities and develop their financial resources to maintain and improve their business performance.
This paper proposes a new methodology for multidimensional poverty measurement consisting of an identification method

that extends the traditional intersection and union approaches, and a class ...of poverty measures
M
α. Our identification step employs two forms of cutoff: one within each dimension to determine whether a person is deprived in that dimension, and a second across dimensions that identifies the poor by ‘counting’ the dimensions in which a person is deprived. The aggregation step employs the FGT measures, appropriately adjusted to account for multidimensionality. The axioms are presented as joint restrictions on identification and the measures, and the methodology satisfies a range of desirable properties including decomposability. The identification method is particularly well suited for use with ordinal data, as is the first of our measures, the adjusted headcount ratio
M
0. We present some dominance results and an interpretation of the adjusted headcount ratio as a measure of unfreedom. Examples from the US and Indonesia illustrate our methodology.

Some scholars hold that dynamic capability (hereinafter DC) is one of the keys to achieving competitive advantage (hereinafter CA) and consequently, performance in strategic management. However, the ...definition and effects of DCs and the role of environmental dynamism are still under discussion. In the context of a Portuguese-like economy and from a strategic process perspective, this study defines dynamic capability as the potential to systematically solve problems, enabled by its propensity to sense opportunities and threats, to make timely decisions, and to implement strategic decisions and changes efficiently, thereby ensuring the right direction. Moreover, the ambidexterity view, exploring the indirect impact of exploitative and explorative capabilities, mediated by creativity and innovation competences (hereinafter IC) gives evidence of the influence on CA and firm's performance. Using an empirical study of 387 enterprises in Portugal, it was found that DCs, creativity and IC do significantly, positively, affect performance, while entrepreneurial orientation (hereinafter EO) is a moderator.

International diversification has become a vital innovation strategy for firms in emerging economies. This study investigates an under-researched topic: the relationships between international ...diversification, capabilities and innovation performance among firms in an emerging economy. We offer a dynamic capabilities explanation for the relationship between international diversification and firms' innovation performance. By employing a large sample of Chinese manufacturing firms, our investigation demonstrates that while international diversification is important in the innovation effort, its effect on innovation performance is mediated through each firm's opportunity-recognizing capability and opportunity-capitalizing capability. The implications of these findings for theoretical development and future research are discussed.
