The struggle for hegemony: the emergence of a counter-public sphere in post-1997 Hong Kong

The present study examines the struggle for hegemony in the public sphere by two different systems, following Hong Kong’s handover to China in 1997. It has been postulated that the new media, particularly social media, has become an important public sphere for the citizens of Hong Kong to engage in an anti-hegemonic struggle against China’s discursive encroachment into Hong Kong since 1997. Given that the public platform provided by legacy media has been bought out or coopted by China, new media has begun to serve as a subaltern public sphere to enable resisting the hegemony imposed by China. This was analyzed through a survey conducted as part of this study, which showed that people who are young, read the Apple Daily, have high expectations of local autonomy, and a high regard for press freedom are prone to using social media to obtain their social and political information. This article analyzes the implications of the emergence of a counter-China hegemonic public sphere.     

Comparing the Explanatory and Predictive Power of Intention-Based Theories of Personal Monetary Donation to Charitable Organizations

The theory of reasoned action (TRA) and the theory of planned behavior (TPB) have been found to have predictive capability in a wide range of personal behaviors. The aim of the study is twofold: firstly, to assess the applicability of the TRA, the TPB, and a newly developed revised version of the TPB in the context of individuals’ monetary donations to charitable organizations; and secondly, to compare the explanatory and predictive power of these three theoretical models. Data relating to intention to give monetary donation, attitudes toward helping others and toward charitable giving, social norms, moral responsibility, and perceived behavioral control were collected in the first phase of the study by means of a self-completion mail questionnaire distributed to 432 residents of Riyadh, Saudi Arabia. In the second phase, 1 month later, telephone interviews were conducted with 221 of the first-phase respondents who had agreed to take part in a follow-up survey of their actual monetary-donating behavior. The findings show that the revised TPB is the best of the three models for predicting individuals’ intention to donate and their future monetary-donation behavior, mainly because moral responsibility is included in the theoretical framework. It thus offers superior explanatory and predictive power.     

The evaluation of socio-economic development of development agency regions in Turkey using classical and robust principal component analyses

In this study, classical and robust principal component analyses are used to evaluate socioeconomic development of regions of development agencies that give service on the purpose of decreasing development difference among regions in Turkey. Due to the high differences between development levels of regions outlier problem occurs, hence robust statistical methods are used. Also, classical and robust statistical methods are used to investigate if there are any outliers in data set. In classic principal component analyse, the number of observations must be larger than the number of variables. Otherwise determinant of covariance matrix is zero. In Robust method for Principal Component Analysis (ROBPCA), a robust approach to principal component analyse in high-dimensional data, even if the number of variables is larger than the number of observations, principal components are obtained. In this paper, firstly 26 development agencies are evaluated with 19 variables by using principal component analysis based on classical and robust scatter matrices and then these 26 development agencies are evaluated with 46 variables by using the ROBPCA method.     

Assessing Type I error and power of multistate Markov models for panel data—A simulation study

Ordinal outcomes collected at multiple follow-up visits are common in clinical trials. Sometimes, one visit is chosen for the primary analysis and the scale is dichotomized amounting to loss of information. Multistate Markov models describe how a process moves between states over time. Here, simulation studies are performed to investigate the Type I error and power characteristics of multistate Markov models for panel data with limited non-adjacent state transitions. The results suggest that the multistate Markov models preserve the Type I error and adequate power is achieved with modest sample sizes for panel data with limited non-adjacent state transitions.     

Equity Ownership in Cross‐border Mergers and Acquisitions by British Firms: An Analysis of Real Options and Transaction Cost Factors

The authors investigate the factors influencing the share of equity ownership sought in cross‐border mergers and acquisitions (CBM&As). Drawing on real options theory and transaction cost economics (TCE), they address and hypothesize key factors linked to commitment under exogenous uncertainty and the separation of desired and non‐desired assets’ influence on share of equity sought by acquiring firms in CBM&As. Empirical analysis based on 1872 CBM&As undertaken by British firms in both developed and emerging economies shows that British MNEs are more likely to pursue a partial acquisition in a target foreign firm when those foreign firms are from culturally distant countries. Further, findings support the view that the high cost of separating desired assets from non‐desired assets motivates firms to make a partial acquisition rather than acquire the target completely. This is one of the first studies to use real options theory to address the cost of commitment under exogenous uncertainty, as well as TCE logic to address the separation of desired and non‐desired assets in the target firm while analysing equity ownership sought in CBM&As. Empirically, this paper contributes by examining CBM&As by British firms in both developed and emerging markets.     

Two-agent scheduling of time-dependent jobs

We consider the problem of scheduling deteriorating jobs or shortening jobs with two agents A and B. We are interested in generating all Pareto-optimal schedules for the two criteria: (1) the total completion time of the jobs in A and the maximum cost of the jobs in B, and (2) the maximum cost of the jobs in A and the maximum cost of the jobs in B. We show that all Pareto-optimal schedules for both problems can be generated in polynomial time, whether the jobs are deteriorating or shortening.     

Managing Retail Shelf and Backroom Inventories When Demand Depends on the Shelf‐Stock Level

Inventory displayed on the retail sales floor not only performs the classical supply function but also plays a role in affecting consumers’ buying behavior and hence the total demand. Empirical evidence from the retail industry shows that for some types of products, higher levels of on‐shelf inventory have a demand‐increasing effect (“billboard effect”) while for some other types of products, higher levels of on‐shelf inventory have a demand‐decreasing effect (“scarcity effect”). This suggests that retailers may use the amount of shelf stock on display as a tool to influence demand and operate a store backroom to hold the inventory of items not displayed on the shelves, introducing the need for efficient management of the backroom and on‐shelf inventories. The purpose of this study is to address such an issue by considering a periodic‐review inventory system in which demand in each period is stochastic and depends on the amount of inventory displayed on the shelf. We first analyze the problem in a finite‐horizon setting and show under a general demand model that the system inventory is optimally replenished by a base‐stock policy and the shelf stock is controlled by two critical points representing the target levels to raise up/drop down the on‐shelf inventory level. In the infinite‐horizon setting, we find that the optimal policies simplify to stationary base‐stock type policies. Under the billboard effect, we further show that the optimal policy is monotone in the system states. Numerical experiments illustrate the value of smart backroom management strategy and show that significant profit gains can be obtained by jointly managing the backroom and on‐shelf inventories.     

Reviewing Leadership Styles: Overlaps and the Need for a New ‘Full‐Range’ Theory

A central topic in leadership research concerns the impact of leadership style – the pattern of attitudes that leaders hold and behaviors they exhibit. Since the year 2000, several new leadership styles have been proposed to capture important missing aspects beyond the dominant charismatic/transformational and transactional framework. The authors review the emerging literature on these new styles – ideological leadership, pragmatic leadership, authentic leadership, ethical leadership, spiritual leadership, distributed leadership, and integrative public leadership – as well as the recent work on servant leadership. They also comment on the Ohio State studies on leadership, and then discuss the ways in which these many styles overlap with transformational leadership and each other, and issue a call to leadership researchers to collectively develop a new ‘full‐range’ model of leadership that encompasses and distills what is unique about these various styles. The authors argue that such an integrated full‐range model is necessary for research on leadership style to progress.     

Breaking bad: an attachment perspective on youth mentoring relationship closures

Endings in youth mentoring relationships have received little attention to date despite the frequency with which they occur. In this paper, we bring an attachment theory perspective to bear on youth mentoring relationship closures and consider how the rich empirical and theoretical literature on attachment can inform mentoring programme practice and possibly help prevent premature and poorly handled mentoring relationship endings. We consider what is known about endings in youth mentoring relationships, articulate an attachment perspective on mentoring relationships and their endings and offer recommendations informed by these literatures for how mentoring programmes can promote positive closure when relationships come to an end.
