REMNANT AMERICAN CHESTNUT (CASTANEA DENTATA(MARSH.) BORKH.; FAGACEAE) IN UPLAND FORESTS OF NORTHWESTERN NEW YORK
Authors: Laport Robert G. 
Published: August 2016

AbstractThe American chestnut (Castanea dentata[Marsh.] Borkh.; Fagaceae) was an historically important hardwood species in eastern deciduous forests of the United States and Canada prior to being nearly eradicated by chestnut blight (Cryphonectria parasitica(Murr.) Barr). Several remnant populations have been identified persisting across fragmented parts of the historical range. The identification and characterization of remnantC. dentatapopulations is important for breeding and conservation efforts, as they may represent potential genetic sources of local adaptation or blight resistance, but much of the historical range remains unsurveyed. Here, I report the locations, blight infection status, and reproductive status of remnant American chestnut in upland forested areas of western New York, finding several reproductive/potentially reproductive trees.
HMeta-d: Hierarchical Bayesian estimation of metacognitive efficiency from confidence ratings
Authors: Fleming Stephen M. 
Published: August 2016

ABSTRACTMetacognition refers to the ability to reflect on and monitor one’s cognitive processes, such as perception, memory and decision-making. Metacognition is often assessed in the lab by whether an observer’s confidence ratings are predictive of objective success, but simple correlations between performance and confidence are susceptible to undesirable influences such as response biases. Recently an alternative approach to measuring metacognition has been developed (Maniscalco & Lau, 2012) that characterises metacognitive sensitivity (meta-d′) by assuming a generative model of confidence within the framework of signal detection theory. However, current estimation routines require an abundance of confidence rating data to recover robust parameters, and only provide point estimates of meta-d’. In contrast, hierarchical Bayesian estimation methods provide opportunities to enhance statistical power, incorporate uncertainty in group-level parameter estimates and avoid edge-correction confounds. Here I introduce such a method for estimating metacognitive efficiency (meta-d’/d’) from confidence ratings and demonstrate its application for assessing group differences. A tutorial is provided on both the meta-d’ model and the preparation of behavioural data for model fitting. Through numerical simulations I show that a hierarchical approach outperforms alternative fitting methods in situations where limited data are available, such as when quantifying metacognition in patient populations. In addition, the model may be flexibly expanded to estimate parameters encoding other influences on metacognitive efficiency. MATLAB software and documentation for implementing hierarchical meta-d’ estimation (HMeta-d) can be downloaded athttps://github.com/smfleming/HMeta-d.
Similar ratios of introns to intergenic sequence across animal genomes
Authors: Francis Warren R. , Wörheide Gert 
Published: August 2016

AbstractOne central goal of genome biology is to understand how the usage of the genome differs between organisms. Our knowledge of genome composition, needed for downstream inferences, is critically dependent on gene annotations, yet problems associated with gene annotation and assembly errors are usually ignored in comparative genomics. Here we analyze the genomes of 68 species across 12 animal phyla and some single-cell eukaryotes for general trends in genome composition and transcription, taking into account problems of gene annotation. We show that, regardless of genome size, the ratio of introns to intergenic sequence is comparable across essentially all animals, with nearly all deviations dominated by increased intergenic sequence. Genomes of model organisms have ratios much closer to 1:1, suggesting that the majority of published genomes of non-model organisms are underannotated and consequently omit substantial numbers of genes, with likely negative impact on evolutionary interpretations. Finally, our results also indicate that most animals transcribe half or more of their genomes arguing against differences in genome usage between animal groups, and also suggesting that the transcribed portion is more dependent on genome size than previously thought.
Excitability in the p53 network mediates robust signaling with tunable activation thresholds in single cells

Published: August 2016

AbstractCellular signaling systems precisely transmit information in the presence of molecular noise while retaining flexibility to accommodate the needs of individual cells. To understand design principles underlying such versatile signaling, we analyzed the response of the tumor suppressor p53 to varying levels of DNA damage in hundreds of individual cells and observed a switch between distinct signaling modes characterized by isolated pulses and sustained oscillations of p53 accumulation. Guided by dynamic systems theory we show that this requires an excitable network structure comprising positive feedback and provide experimental evidence for its molecular identity. The resulting data-driven model reproduced all features of measured signaling responses and is sufficient to explain their heterogeneity in individual cells. We present evidence that heterogeneity in the levels of the feedback regulator Wip1 sets cell-specific thresholds for p53 activation, providing means to modulate its response through interacting signaling pathways. Our results demonstrate how excitable signaling networks can provide high specificity, sensitivity and robustness while retaining unique possibilities to adjust their function to the physiology of individual cells.
Reflections on Blended Learning: A Case Study at the Open University of Hong Kong
Authors: Bo Tso Anna Wing 
Published: August 2016

Teaching presentation skills is by no means an easy task. To teach such skills effectively, a teacher must help the students to learn how to (1) design and organize the presentation contenteffectively; (2) strengthen their verbal and nonverbal communication skills;and (3) master the use of visual aids. Often, the traditional face-to-face classroom setting falls short when the lecturer has to teach more than 100 students how to observe small details of body language and vocal skills. In this case, a blended learning mode — a hybrid of face-to-face and online learning — may be a better option than a pure face-to-face learning mode (Fang, Chow & Soo, 2012).
The purpose of this paperis to demonstrate how blended learning can be implemented to teach university students' presentation skills. In the spring term of 2013, ENGL A122F: Presentation Skills, a five-credit course for full-time undergraduate students, was first delivered via a blended learning approach at the Open University of Hong Kong. Attempting to combine the best features of the online and face-to-face modes of teaching, the blended delivery course incorporated video and interactive web-based components into the course outline.
In this paper, I share my experience of how presentation skills can be taught through video lectures and assessed through the online learning environment (OLE), alongside traditional teacher-led lectures and tutorials. Also, I discuss how the blended learning approach, compared with the traditional face-to-face teaching mode, can not only facilitate propositional knowing, but also help learners to achieveexperiential knowing, and presentational knowing (Heron & Reason, 2006). Last but not least, the paper reflects on students'feedback, as well as the challengeswhen implementing the blended learning mode.
Movement characteristics of micro drill bit during entry period in PCB high speed drilling
Authors: Shi Hongyan , Yan Qiuxin , Chen Shengzhi 
Published: August 2016

Purpose
The purpose of this paper is to study the movement characteristics of micro drill bit during entry period in printed circuit board (PCB) high-speed drilling and to present an effective method to conduct quantitative analysis of the wandering of drill bit based on high-speed video capturing.

Design/methodology/approach
Based on the high-speed camera technology, experiments are conducted to get a series of time sequence images and the wandering of micro drill tip and the radial run-out of drill body, and the max-deformation of drill bit are calculated by using a quantitative analysis method. Finally, the movement characteristics of micro drill bit during entry drilling period PCB high-speed drilling are evaluated.

Findings
With the increasing spindle speed, the radial run-out of drill body decreases gradually, whereas the wandering amplitude of the drill point gradually increases; micro drill bit itself has an ability of positioning deviation correction after contacting the entry sheet; the feed rate within a certain range could slightly worsen the deformation of drill tip at the instant of impingement.

Research limitations/implications
With the improvement of spindle speed, the camera’s shooting speed needed will increase accordingly, thus, the resolution of the pictures will decline, which always affects the analysis precision.

Originality/value
A series of effective methods to conduct quantitative analysis of the wandering micro drill bit by using high-speed camera technology is presented; a reference for the optimization of micro-hole drilling is provided.
The relevance and promise of relational mentoring for school leadership: a conversation
Authors: Cowin Kathleen M. , Gates Gordon S. , Luckett Kathleen 
Published: August 2016

Purpose– Studies uniformly portray the assistant principal (AP) position as challenging given a number of systemic issues that negatively impact job satisfaction and performance. Mentoring has been proposed as a way to redress these problems. The purpose of this paper is to illuminate an alternative to traditional mentoring and make recommendations for how to utilize this approach in supporting APs and principal interns.Design/methodology/approach– The authors employ a retrospective and conversational approach, sharing incidents and interactions from their professional experience and making connections to existing research literature. The authors explain the relevance of three concepts developed in relational cultural theory (RCT) including: interdependent self-in-relation, growth-fostering interactions, and an exploration of systemic power.Findings– The narrative exposes the ambiguity of school leadership and its toll, as well as how relational mentoring facilitates integration and making sense of challenging experiences for improved coping. Barriers in communication are described and the ways relational mentoring addresses these weaknesses by building trust, recognizing the expertise of mentor and protégé, and encouraging protégé empowerment and judgment.Research limitations/implications– Potential research limitations such as inaccuracies in recall, reliance on a single method, and hindsight bias are recognized and addressed to reduce their threat.Practical implications– RCT may provide ways to develop and structure more effective mentoring programs and educate both aspiring leaders and their mentors in their work together to provide for leadership development.Social implications– Improved mentoring practices have the potential to help APs socialize into the role more quickly and become more effective school leaders.Originality/value– The authors describe the use of RCT in a new context. The paper provides insights and guidance for APs, principals, principal interns, and leadership preparation faculty to offer a pathway on which to prepare the next generation of school leaders equipped with the desired competences and experiences to transform schools.
Supporting the development and professional growth of middle space educational leaders through mentoring
Authors: Searby Linda  J. , Armstrong Denise 
Published: August 2016

Purpose
– The purpose of this paper is to introduce readers to the special issue on “middle space” education leaders (those individuals who are second-in-command in schools). The special issue contains papers pertaining to mentoring those preparing for and aspiring to the assistant school leader role, as well as papers on programs that support new assistant principals/vice-principals through mentoring and coaching. The authors provide background on middle space leadership and mentoring from existing research literature, introduce the international papers selected for the issue, and identify unifying themes across the papers.

Design/methodology/approach
– The authors provide highlights of relevant research literature on the importance of mentoring for school leaders in general, but also specifically address the need for mentoring for middle space leaders from the scant literature that exists on the topic. After reviewing the relevant literature, the authors provide an overview of the seven papers that were chosen for the issue through a rigorous peer-review process.

Findings
– The co-editors of this special issue identify common themes that emerged from the papers chosen for the issue. In general, authors note that middle space leaders have unique mentoring and coaching needs, and there are few formal programs that address their needs. However, there is a growing awareness of the need to support assistant principals through structured mentoring programs, as well as preparing and mentoring those who aspire to the position.

Research limitations/implications
– The seven papers chosen for the special issue represent a variety of research methodologies. A limitation is that the majority of the studies are qualitative, with small sample populations. However, even with small sample sizes, commonalities can be seen across the studies and across international contexts.

Practical implications
– This review summarizes the issues facing middle space leaders in education and how they can be effectively addressed. The global audience that can benefit from engaging with the papers in this special issue includes educational leadership faculty, educational governing bodies, policymakers, school district central office personnel, senior principals, and assistant principals themselves.

Originality/value
– This paper and the seven that follow extend the scant research literature in the realm of middle space leaders in education. They provide unique insights – from different international contexts including the USA, Canada, Hong Kong, and New Zealand – into the need for and potential benefits of mentoring and coaching aspiring and new middle space leaders.
Indirectly productive entrepreneurship
Authors: Padilla Alexandre , Cachanosky Nicolás 
Published: August 2016

Purpose
– Since Baumol (1990), the economic literature has distinguished between two broad categories of entrepreneurship: productive and unproductive. The purpose of this paper is to introduce another subcategory: indirectly productive entrepreneurship. Sometimes, profit-seeking entrepreneurs allocate their talents to indirectly productive activities to mitigate the new costs market participants endure as a result of a government regulation. The resources used to mitigate these costs must be diverted from other uses.

Design/methodology/approach
– This paper uses the example of cell phone storage outside New York City’s high schools to illustrate an indirectly productive entrepreneurial activity that mitigates the inefficiencies or costs created by a regulation. These costs and the resulting entrepreneurship would not have arisen absent the regulation.

Findings
– These profit opportunities do not result from market entrepreneurial errors or successes but emerge from inefficiencies or unintended consequences produced by government regulations. When evaluating such entrepreneurship, the question is whether such regulation is desirable from an efficiency viewpoint because such entrepreneurship, while making such regulation less inefficient or less costly, diverts resources from other lines of production.

Originality/value
– This paper identifies a new category of entrepreneurship: indirectly productive entrepreneurship. This paper also shows that government regulation often deters productive entrepreneurship. However, under some circumstances, regulation can indirectly encourage productive entrepreneurship by creating artificial profit opportunities that would not have existed otherwise.
Understanding foreign direct investment in Indonesia
Authors: Gopalan Sasidaran , Hattari Rabin , Rajan Ramkishen S. 
Published: August 2016

Purpose
This paper aims to examine the dynamics of foreign direct investment (FDI) inflows into Indonesia. It is interested specifically in analysing and deliberating on two important policy questions: First, are all kinds of FDI useful from a policy perspective and what does the existing data on FDI reveal about the type of FDI inflows into Indonesia? Second, does the existing data help understand the extent of de facto bilateral linkages between Indonesia and other countries?

Design/methodology/approach
The paper offers an in-depth case study of Indonesia using extensive exploratory data analysis on FDI inflows into Indonesia. As discussed in the paper, the data investigation uses and reconciles available FDI data both from national and international sources to understand the usefulness of such data for policy analysis.

Findings
A data investigation of the trends in different types of FDI flows reveals a discernible downward trend in the ratio of mergers and acquisitions (M&A)–FDI ratio over the years. The paper argues that from a sequencing perspective, while a medium-to-long-term framework encouraging both domestic and foreign Greenfield investments could help Indonesia regain its growth luster, in the near term much more attention needs to be paid to FDI inflows in the form of M&As. Further, reconciling FDI and M&A data might help identify the original sources of FDI flows because existing data are based on flow of funds rather than ultimate ownership.

Practical implications
Since the Asian financial crisis, Indonesia has successfully embarked on a phase of economic and political transition post-Suharto, with the cornerstones of such a strategy being a process of greater democratisation and decentralisation. However, there have been growing concerns of economic growth stagnation in recent years. One of the policies to revive the economy’s lustre adopted by the government has been to attract greater FDI inflows. In this light, this paper examines the dynamics of FDI into Indonesia and deliberates on what kinds of FDI policymakers should focus on attracting to restore the country’s growth lustre.

Originality/value
The question of whether a policy to attract FDI should be careful in distinguishing the kind of FDI it wants to attract has not been sufficiently addressed in the related literature. This paper provides a framework to understand the different macroeconomic policy implications of types of FDI and provides extensive data analysis to not only understand the types of FDI but also sources of bilateral FDI inflows to Indonesia by reconciling FDI and M&A data.
Fiscal policies in EMU countries: strategies and empirical evidence
Authors: Forte Francesco , Magazzino Cosimo 
Published: August 2016

Purpose
The aim of the paper is to evaluate fiscal adjustments that have occurred in the Economic and Monetary Union (EMU) countries in the last 35 years, and their consequences on the economic growth process by using the mean group (MG) estimators.

Design/methodology/approach
Our emphasis is on the effects of different composition of fiscal stimuli and consolidations. We compare the effects on the economic growth rate of different compositions of major fiscal changes. We use a cyclically adjusted value of the fiscal variables to leave aside variations of the fiscal variables induced by business cycle fluctuations.

Findings
Our empirical research of the effects of large changes in fiscal policy, both in case of a fiscal consolidation and of fiscal stimulus in the 18 EMU countries from 1980 to 2015, shows that adjustments by cutting current expenditures, rather than by tax increases are more likely to boost economic growth. It also shows that cuts of investment expenditures may reduce GDP growth. During fiscal stimulus episodes, tax cuts and public investments are more likely to increase growth than current public expenditure.

Originality/value
This is the first study devoted to the EMU countries. It should be underlined that the results obtained as for EMU countries are not necessarily applicable to other countries, as the different government size as well as different market institutions may influence the results.
Does Facebook usage lead to conspicuous consumption?
Authors: Taylor David G. , Strutton David 
Published: August 2016

Purpose
The purpose of this study is to demonstrate how Facebook usage is positively related to envy and narcissism, which in turn increase users’ desire for self-promotion and propensity to engage in conspicuous consumption.

Design/methodology/approach
Data were collected via an online survey, with 674 usable responses collected from Facebook users of all ages.

Findings
The results support the hypotheses that increased Facebook usage is positively related to envy and narcissism. These two psychological constructs lead to stronger desires for self-promotion, spurring the behavioral response of conspicuous online consumption.

Research limitations/implications
The findings are limited to the self-reported behaviors of a limited sample. Despite the limitations, the findings identify a process by which increased Facebook usage results in an increased desire to promote oneself through conspicuous consumption.

Practical implications
An understanding of the psychology linking social media use to conspicuous consumption can aid managers in developing marketing strategies to encourage the purchase and usage of positional goods. Specifically, more frequent users may be targeted by advertisers wishing to encourage the purchase and display of their products.

Social implications
Facebook usage appears to elicit emotions – such as narcissism and envy – that most researchers would consider socially undesirable.

Originality/value
An emerging stream of research suggests that social media usage elicits both positive self-comparisons with others (i.e. narcissism) and negative (i.e. envy). This study is among the first to empirically test this effect on the purchase and consumption of positional goods.
