The birds and the bees: interactive graphics and problem solving in the teaching of statistics

Software which allows interactive exploration of graphical displays is widely available. In addition there now exist sophisticated authoring tools which allow more general textual and graphical material to be presented in computer-based form. The role of an authoring tool in providing a graphical interface to a strategy for solving simple statistical problems in the context of teaching is discussed. This interface allows a variety of resources to be integrated. Specific examples, including the use of dynamic graphical displays in exploring data and in communicating the meaning of a model, are proposed. These ideas are illustrated by a problem involving the identification of the sex of a herring gull.     

How the Resource-based and the Dynamic Capability Views of the Firm Inform Corporate-level Strategy

This paper explains that the resource‐based view essentially addresses issues of competitive strategy, but by integrating some arguments from its evolutionary version, the dynamic capability view, it can be extended to inform our understanding of corporate‐level strategy. We concentrate on the issue of value creation from corporate centres and ask how the centre can possess or provide resources. The primary dynamic capabilities identified by Teece, Pisano and Shuen (1997) are elaborated into six distinct modes of resource creation. Each mode is considered in relation to a set of organizational design parameters. We then propose resource‐creating configurations that are congruent with respect to the modes and the required states of the design parameters. We point out areas of tension that are likely to arise if corporations try to combine different modes of resource creation. We conclude that corporate centres may possess resources but must display dynamic capabilities otherwise they will destroy shareholder value.     

‘Surrounded with so much uncertainty’: asylum seekers and manufactured precarity in Australia

In Australia, nearly 30,000 asylum seekers have the legal right to work, but their temporary and conditional migration status exposes them to work-related precarity. This article draws on a small qualitative study that examined asylum seekers’ experiences of seeking work and achieving economic security. Over an 18-month period, 29 semi-structured interviews with asylum seekers who had work rights in Australia were conducted. It provides insights into how restrictive immigration policies manufacture precarity through short-term, conditional visas, resulting in employer risk aversion, segmentation into insecure work, and in-work instability and mistreatment. Asylum seekers manage their experiences and feelings of pervasive insecurity through individual coping and survival strategies.     

The reliance on recognition and majority vote heuristics over privacy concerns when selecting smartphone apps among German and US consumers

The smartphone app market is a prime example of a digital market where consumers are tasked with selecting one option among a plethora of alternatives, at times indistinguishable from one another. Building upon findings on information processing and decision-making, we postulate that consumers follow simple (rather than complex) heuristic rules to navigate the app market. In particular, we focus on two such strategies: the recognition heuristic and the majority vote heuristic. App privacy information was also considered as a potentially salient cue in the decision-making process, given the personal data stored on smartphones. Results of a mixed-method design (behavioral analysis and think-aloud protocols) study with German (N?=?18) and US (N?=?25) students find a dominance of the recognition heuristic. Decisions are further supported by majority vote heuristics. Privacy information is largely disregarded, particularly by US participants. Implications for app market design and engagement are discussed.     

Sums of powers of binomial coefficients

An asymptotic series for sums of powers of binomial coefficients is derived, the general term being defined and usable with a computer symbolic language. Sums of squares of coefficients in the symmetric case are shown to have a link with classical moment problems, but this property breaks down for cubes and higher powers. Problems of remainders for the asymptotic series are mentioned. Using the reflection formula for I'(.), a continuous form for a binomial function is set up, and this becomes oscillatory outstde the usual range. A new contmued fraction emerges for the logarithm of an adjusted sum of binomial squares. The note is a contribution to the problem of the interpretation of asymptotic series and processes for their convergence acceleration.     

Famine Mortality in Nineteenth-Century Japan: The Evidence from a Temple Death Register

Economic and demographic historians who have studied Japan's early modern period argue that preventive checks to fertility were the primary cause of Japan's stationary population in the eighteenth and early nineteenth centuries, and that the role of ‘positive’ checks was negligible. This paper presents evidence and a claim that mortality crises – famines in particular – also played an important role in checking population growth during this period. It analyses data from the death register of Ogen-ji, a Buddhist temple in the Hida region of central Japan. These data provide a remarkably detailed picture of the short-term demographic consequences of Japan's last great famine, the Tenpō famine of the 1830s. ‘Normal’ mortality patterns, by age and sex, are compared with patterns of mortality during the famine. Mortality of males rose considerably more than that of females, with the greatest rise occurring among young boys aged 5–14 and adult men aged 30–59. A surprising finding was that mortality at ages 0–4 rose relatively little, in part a consequence of a marked fall in the number of births during the famine. The Tenpō subsistence crisis was not the sole cause of population stagnation in the Ogen-ji population, but it was a prominent feature of the ‘high mortality regime’ that this population experienced during the eighteenth and nineteenth centuries.     

Evaluation of the parameters of su by rational fractions

A rational fraction approximation is given for a function of one of the parameters defining Johnson's S_UError assessment for a segment of the domain of validity shows remarkable accuracy.     

The Development of Vocational Realism in Black American College Students

A total of 172 Black students completed a survey of biographical, educational, and vocational information about themselves and their immediate relatives. The results indicated that educational realism tended to increase across the college years. There was no difference in satisfaction with school or intent to leave school as a function of educational realism or salary realism. Vocationally realistic male and female students did not differ in age.
