A residual-based test of the null of cointegration in panel data

This paper proposes a residual-based Lagrange Multiplier (LM) test for the null of cointegration in panel data. The test is analogous to the locally best unbiased invariant (LBUI) for a moving average (MA) unit root. The asymptotic distribution of the test is derived under the null. Monte Carlo simulations are performed to study the size and power properties of the proposed test.

overall, the empirical sizes of the LM-FM and LM-DOLs are close to the true size even in small samples. The power is quite good for the panels where T ≥ 50, and decent with panels for fewer observation in T. In our fixed sample of N = 50 and T = 50, the presence of a moving average and correlation between the LM-DOLS test seems to be better at correcting these effects, although in some cases the LM-FM test is more powerful.

Although much of the non-stationary time series econometrics has been criticized for having more to do with the specific properties of the data set rather than underlying economic models, the recent development of the cointegration literature has allowed for a concrete bridge between economic long run theory and time series methods. Our test now allows for the testing of the null of cointegration in a panel setting and should be of considerable interest to economists in a wide variety of fields.     

Sense of belonging and depressive symptoms among GLB adolescents

Research has indicated that gay, lesbian, and bisexual (GLB) adolescents are at an increased risk of mental health problems. Research has also indicated that experiencing a sense of belonging is important for one's mental health. This study investigated sense of belonging to the general community and sense of belonging to a GLB specific youth group (Minus18) as predictors of depressive symptoms among self-identified GLB adolescents (N = 99). Participants completed the Sense of Belonging Instrument and Center for Epidemiologic Studies Depression Scale. Results showed that although sense of belonging to the general community and sense of belonging to the Minus18 community were both directly related to depression, only sense of belonging to the general community contributed significantly to the prediction of depression when they were entered simultaneously in a regression analysis. Results also showed that sense of belonging to the general community mediated the relation between sense of belonging to the Minus18 community and depression. These findings suggest that interventions aimed at increasing sense of belonging to a GLB-specific community are likely to be of indirect benefit to the mental health of GLB adolescents, whereas interventions aimed at increasing sense of belonging to the general community are likely to be of direct benefit to the mental health of GLB adolescents.     

The Ethnic Minority Question and Rohingya Crisis in Contemporary Myanmar

The recent humanitarian Rohingya crisis has once again put Myanmar onto the centre stage of global media attention. The aim of this paper is to look into the ethnic minority question in contemporary Myanmar. The paper has a special focus on the Muslim Rohingya community. The paper argues that problematic race relations in Myanmar today should not be viewed in isolation but should be seen as a part of a historical continuum. The British colonial policies of divide and rule, political leaders and their obsession with Buddhism in the post-independence period and xenophobic tendencies during the long years of the military junta have all collectively contributed to the very complex situation in which the country finds itself today when it comes to race relations. Meaningful democracy and economic development have been advocated as the way forward especially for the more peripheral parts of the country where there is a strong ethnic minority presence.     

Effects of a sleep hygiene text message intervention on sleep in college students

Objective: To test the effectiveness of a text-message intervention to promote sleep hygiene to improve sleep in young adult college students. Participants: A convenience sample of undergraduate students from one Southwestern university (n = 96), 18–26 years old, recruited in August 2015. Methods: A 2-group pretest-posttest experimental design assigned participants to receive biweekly text messages about sleep hygiene or healthy behaviors for 6 weeks. Survey questions addressed sleep knowledge, sleep hygiene, self-efficacy for sleep hygiene, and sleep quality at baseline and posttest. Results: Though not significant, sleep quality, sleep hygiene, and sleep knowledge improved in both groups. Conclusions: Self-efficacy for sleep hygiene is a modifiable factor that may serve to improve sleep quality. Sleep quality improved in both groups. Text messaging is a feasible approach to delivering an intervention to promote healthy behaviors among young adults.     

Experiences of Grandparenting Disabled Children in the UK: A Qualitative Study of Intergenerational Relationships

Contemporary patterns of family, work, and welfare make the experience of grandparenting complex and diverse. This UK-based qualitative study aimed to explore grandparenting in the context of childhood disability. Nine grandparents (aged 59–79 years) with disabled and non-disabled grandchildren took part in semi-structured interviews. Grandparents provided extensive instrumental and emotional care and support and sought a balance between involvement versus interfering. Grandparents actively drew on life experiences to engage with services to maximize support. Contemplating the future, grandparents had concerns for adult children as well as grandchildren. Developing policies to support grandparents of disabled grandchildren are urgently required.     

A Note on the Dimensionality of Quality of Life Scales: An Illustration with the Satisfaction with Life Scale (SWLS)

A case is made that measures used in quality of life and happiness research will be essentially unidimensional: inherently tapping minor dimensions. This is illustrated using Diener’s Satisfaction with Life Scale (SWLS). It is shown that the SWLS does not meet the standard of strict unidimensionality, but that the interpretation of the total scale score is not compromised because the additional dimensions are relatively minor. In the context of the example, a multi-step strategy is described that allows researchers to test for essential unidimensionality. Throughout the article, essential unidimensionality is contrasted with the received view of strict unidimensionality and confirmatory factor analysis methods.

Choice in ordered-tree-based decision problems

Decision makers often have to choose alternatives which appear in an exogenous structure. For example, consider choosing a dish in a restaurant after going through different menu cards (a menu card for buffet, another for combo offers etc.). The decision maker observes the items displayed (as a list) on a menu card and she switches to another menu card to see the items displayed on it (again in the form of another list). Thus the set of all items appears as an “ordered-tree” to the decision maker. There are other examples of decision making where alternatives appear in the form of an ordered-tree. In this paper we consider the cases of choice from ordered-trees (in particular, “lists of lists”) and characterize the choice functions. We impose the axioms of Backward Consistency and Replacement Indifference on choice functions and obtain characterization results for \(k\) -ary ordered-trees and more general ordered-trees. We show that the results for \(k=2\) are similar to those of (Rubinstein and Salant 2006), in which the cases of choice from lists are considered. However the results for \(k \ge 3\) and general ordered-trees are different and allow for instance, a richer class of tie-breaking rules in special cases.
